Definitions
- This invention relates generally as indicated to an adjustable work station and accessories therefor and more particularly to a work station useful for utilizing electronic equipment such as computers, word processors, and the accoutrements thereof.
- IBM Corporation offers SYNERGETIX furniture for its electronic equipment.
- SYNERGETIX is a registered trademark of IBM.
- the principal component of such work station is an adjustable terminal base which includes manual height adjustments for various work surfaces.
- the platform supporting the video display terminal or CRT may be manually tilted or swivelled. All such manual height adjustments are provided in the base, and for an operator to make such adjustments may require a number of tedious "ups and downs" before the adjustments are comfortable.
- Other drawbacks of such work stations are their designed single utility. In other words they are not suitable as a work station except when utilizing the electronic equipment involved. Another drawback is their appearance and adaptability. In fact, such work stations have become known as "machine tables" whether the adjustments are manual or motorized.
- Such machine tables are generally quite discordant in an open office layout. They have the appearance of belonging in a workshop or supporting a special machine and cannot readily fit into the environment of a modern interior open office design. Although intended to be ergonomically effective, such work stations are quite visually and environmentally incompatible with the visual and accoustical problems prevalent in ergonomically effective office layouts. For example, such machine tables do not relate well to a more conventional office layout utilizing filing or storage cabinets, visual or accoustical screens, or modular systems providing work stations which may be utilized beyond the use of the equipment intended.
- a work station useful not only for conventional purposes but also particularly useful for utilizing electronic equipment such as computers, word processors and the accoutrements thereof.
- Such work station provides a wide variety of adjustments such as leveling, elevation, angle and position, not only of work surfaces, but also of attached cabinets, printers, disc readers, etc., as well as individual adjustment of accessories such as video screens or CRT terminals, copy holders, phone pads, task lights, trays, etc., all to provide an ergonomically effective adjustable work station that takes into account the human factors data available for 95% of the population.
- Major component adjustment may be power driven.
- the elevation of the major work surfaces and attached components may be controlled by switches readily available to the user.
- major components such as the video display terminal.
- Wiring access may be provided through selected dedicated outlets in a wiring tray beneath the major work surface which may be exposed by sliding or pivoting such work surface, such pivoting being at the point adjacent the user.
- the pivot housing also provides a housing for actuators which may control power height adjustment of the major work surface and certain attached accessories as well as the in-and-out sliding or pivoting of such major work surface.
- the support for the major work surface slide includes a slot or recess by which wiring may connect to lateral support surfaces. Such slot also precludes the user pinching his or her fingers in the event of angular adjustment or movement of the major work surface.
- the work station is essentially modular in component and form, the major structural elements of which are two spaced apart two-part telescoping square-in-section vertically adjustable legs which are interconnected by two spaced apart beams providing an open slot therebetween.
- the beams include on the interior thereof a track forming vertically spaced rails. Such rails support a wide variety of accessories either for adjustable clamping thereto or rolling therealong.
- One such accessory is a support for a video display screen (CRT) which is mounted on rollers for free rolling movement along one of the tracks and which-includes a manual or power driven adjustment for height, angle, and position with respect to the user.
- CTR video display screen
- Figs. 1-8 there is illustrated the more basic components of the work station of the present invention.
- Such components comprise two spaced legs 40 which may be in all respects identical.
- Each leg includes a lower square-in-section component 41 and an upper similar square-in-section component 42 which telescopes over the component 41.
- a rotating screw is journaled in the upper component 42 and is in mesh with a nut secured to the lower component 41. Rotation of the screw will vertically adjust the height of the leg.
- each component of the legs 41 and 42 at the top and bottom is provided with mounting holes seen at 44, by which a wide variety of arms and/or feet may be secured to the flat faces of the components at the top and bottom projecting therefrom.
- a fixed glide seen at 46 may be secured in the bottom component and a removable leg cap cover 47 is adapted to fit closely over recessed top 48.
- each leg 40 is provided with a foot 50 projecting toward the viewer and to the right, such foot being secured to the corresponding face of the bottom of the leg component 41 by suitable fasteners fitting through the screw holes 44.
- the end of the foot is provided with an adjustable glide 51.
- the foot may be covered by a foot cover 52.
- Screw ports 44 when not utilized, may be covered by screw covers 53.
- each beam is formed of a sheet metal structure and includes an outer plate 59 and an inner stiffening plate 60 which may be bent to form three horizontally extending rectangular ribs 61.
- the outer plate is inwardly folded to form a flange 62 and then folded again on itself or hemmed as indicated at 63.
- the inner plate is inwardly folded at its edges to form a short flange 64 which fits behind the folded edge 63 of the outer plate.
- the two plates of each beam may be spot welded together where contiguous.
- each beam is rounded as indicated at 66 in the same fashion as the corners of the leg components are also rounded as seen at 67.
- Secured to the upper components of the legs are vertically spaced facing U-shape brackets seen at 68.

- the face of each beam is slightly recessed as indicated at 72 to accommodate cap screws 73 which secure the beams to the brackets in the manner indicated more clearly in Figs. 1 and 8.
- each of the top two rectangular ribs 61 Secured to the interior of each of the top two rectangular ribs 61 is a horizontally extending plate in a vertical plane as seen at 76 and 77, the top and bottom horizontal and parallel edges 78 and 79 -of which form top and bottom rails, respectively.
- the plates are secured to the beams to form tracks, and the top and bottom edges thereof form rails to accommodate either for clamping or rolling movement therealong a wide variety of accessories hereinafter described.
- the top and bottom edges of the plates may be rounded, beveled, or hemmed to remove rough edges and better to accommodate the accessories. In the illustrated embodiment there is approximately a 4 cm. clearance between the two rails which permits accessories to be clamped to or mounted on both rails concurrently.
- each beam is provided with a row of horizontally elongated holes extending through both the inner and outer plates thereof, such rows being seen at 80 and 81.
- a wide variety of accessories may be mounted directly on the face of the beams to project in cantilever fashion therefrom.
- such accessories may include drawer units, filing units, back files, or hanging files, as well as specially designed cabinets for printers or disc readers, and surface supports.
- supports 83 and 84 may be secured to the upper components 42 of the legs 40 and 41 through the screw mounting holes 44 to project in cantilever fashion in the same direction as the feet 50.
- the top supports are designed to support a work top or surface 85.
- Each top support includes an underlying arm 86 and an overlying slide 87 which are hingedly interconnected at their distal or outer ends at 88. The outer end is of course the end of the support or edge of the work surface toward the user.
- the work surface 85 is relatively thin and is primarily a sheet metal structure rigidified by a honeycomb core. Its underside at each lateral edge may be provided with a T-shape channel which fits on the slides 87.
- the work surface is mounted on the slides for in and out sliding movement or towards and away from either the user or the slot 75 provided by the spaced apart beams 55 and 56.
- the surface 85 may be released for such sliding movement by a spring loaded latch seen more clearly in Fig. 2 at 90 which projects through a rectangular hole 91 in slides 87.
- the slide as seen also in Fig. 2 is provided with a slide surface 92 which is mounted on an underlying relatively shallow channel-shape frame 93 which includes, at its distal end, downwardly projecting ears 94 and 95 each of which includes holes 96.
- Such holes are adapted to be aligned with similar holes in upstanding ears 97 and 98 on the end of support arm 86. It is through such aligned holes that such arm and slide are hingedly interconnected by hinge pin 99.
- the hinge pin not only extends through the holes in the aligned ears of the arm and slide, but also through a plastic actuator housing 101.
- the actuator housing primarily provides a mounting for pivoting paddle 102 for releasing catch 90 as well as sawtooth motor switch 103 controlling, for example, the motorized adjustment of the height of the leg or legs.
- the actuator or plastic switch housing 101 is a one-piece molded plastic part which includes a central web 105 which at its inner end has a laterally projecting ear 106 and an inverted L-shape wire shield 107.
- the ear includes a hole 108 adapted to align with hole 109 in spring 110 of spring catch 90. Both such holes are adapted to fit over a projecting stud on the under surface of the slide 87 and may be held thereto by a suitable fastener with the spring catch 90 then projecting through the hole 91.
- Each block includes near its inner end slots as seen at 114 and 115 which are separated by upstanding outer and inner ears 116 and 117, each outer ear having hole 118 while each inner ear has upwardly opening slot 119.
- Such holes and slots are aligned and also aligned with a corresponding slot 120 in the web 105.

Abstract
A work station useful for conventional purposes and also particularly useful for utilizing electronic equipment such as computers, word processors and the accoutrements thereof is provided which includes a wide variety of adjustments such as leveling, elevation, angle and position, not only of work surfaces, but also of attached cabinets, printers, disc readers, etc., as well as individual adjustment of accessories such as video screens, line readers, phone pads, task lights, trays and the like, all to provide an ergonomically effective adjustable work station. Major component adjustment may be power driven. Wiring access is provided through outlets in a wiring tray (195) beneath the major work surface (85) which may be exposed by sliding or pivoting such work surface, such pivoting being at a point adjacent the user. The support for the work surface slide includes a slot or recess (200) by which wiring may connect to lateral support surfaces. The work station is modular in component and form, the major structural elements of which are two two-part telescoping adjustable legs (40) which are interconnected by two spaced apart beams (55, 56) providing an open slot therebetween. Each beam includes on the interior thereof a track (76, 77) forming vertically spaced rails (78, 79). Such rails support a wide variety of accessories either for adjustable clamping thereto or rolling therealong. One such accessory is a support for a video display screen which is mounted on rollers for free rolling along one of the tracks and which includes an adjustment for height, angle, and position with respect to the user, such adjustments being manual or power driven.
Description
- This invention relates generally as indicated to an adjustable work station and accessories therefor and more particularly to a work station useful for utilizing electronic equipment such as computers, word processors, and the accoutrements thereof.
- Most work stations in the form of desks or tables are rather lacking in adjustability. For most office desks, whether they be secretarial or executive, there is generally no adjustability and the user generally conforms to the work surface by adjusting the chair. Such adjustments are like a procrustean bed if the user doesn't fit certain norms in height, weight and build. Also, such seemingly minor human characteristics as arm reach, or optically adjusted eyesight, can create further aggravating problems at any work station. Anyone with bifocal or trifocal glasses can appreciate the problem.
- The problem becomes more acute with the advent of computer or word processing work stations. The user must have proper physical and visual access to a wide variety of items at any given work station such as video display terminals, keyboards, copy readers, printers, filing systems, disc readers, and the similar accoutrements of the electronic age.
- The problem becomes even more acute when more than one person is expected to have access to such equipment at a given work station. Unless each user fits a certain fairly narrow range of norms, it is apparent that considerably adjustment will be required to make the work station ergonomically effective for a particular user. Moreover, if the task is short at such work station, more time may be spent making the adjustments than performing the task.
- Some electronic equipment makers have developed specialized work stations. For example, IBM Corporation offers SYNERGETIX furniture for its electronic equipment. SYNERGETIX is a registered trademark of IBM.
- The principal component of such work station is an adjustable terminal base which includes manual height adjustments for various work surfaces. In addition, the platform supporting the video display terminal or CRT may be manually tilted or swivelled. All such manual height adjustments are provided in the base, and for an operator to make such adjustments may require a number of tedious "ups and downs" before the adjustments are comfortable. Other drawbacks of such work stations are their designed single utility. In other words they are not suitable as a work station except when utilizing the electronic equipment involved. Another drawback is their appearance and adaptability. In fact, such work stations have become known as "machine tables" whether the adjustments are manual or motorized.
- Such machine tables are generally quite discordant in an open office layout. They have the appearance of belonging in a workshop or supporting a special machine and cannot readily fit into the environment of a modern interior open office design. Although intended to be ergonomically effective, such work stations are quite visually and environmentally incompatible with the visual and accoustical problems prevalent in ergonomically effective office layouts. For example, such machine tables do not relate well to a more conventional office layout utilizing filing or storage cabinets, visual or accoustical screens, or modular systems providing work stations which may be utilized beyond the use of the equipment intended.
- It is accordingly desirable to provide an ergonomically efficient modular work station overcoming the problems presented by presently available machine tables and other less adjustable work stations. It is also desirable to provide such modular work station as well as a wide variety of accessories therefor.
- By the present invention there is provided a work station useful not only for conventional purposes but also particularly useful for utilizing electronic equipment such as computers, word processors and the accoutrements thereof. Such work station provides a wide variety of adjustments such as leveling, elevation, angle and position, not only of work surfaces, but also of attached cabinets, printers, disc readers, etc., as well as individual adjustment of accessories such as video screens or CRT terminals, copy holders, phone pads, task lights, trays, etc., all to provide an ergonomically effective adjustable work station that takes into account the human factors data available for 95% of the population.
- Major component adjustment may be power driven. For example, the elevation of the major work surfaces and attached components may be controlled by switches readily available to the user. The same is true of major components such as the video display terminal.
- Wiring access may be provided through selected dedicated outlets in a wiring tray beneath the major work surface which may be exposed by sliding or pivoting such work surface, such pivoting being at the point adjacent the user. The pivot housing also provides a housing for actuators which may control power height adjustment of the major work surface and certain attached accessories as well as the in-and-out sliding or pivoting of such major work surface.
- The support for the major work surface slide includes a slot or recess by which wiring may connect to lateral support surfaces. Such slot also precludes the user pinching his or her fingers in the event of angular adjustment or movement of the major work surface.
- The work station is essentially modular in component and form, the major structural elements of which are two spaced apart two-part telescoping square-in-section vertically adjustable legs which are interconnected by two spaced apart beams providing an open slot therebetween. The beams include on the interior thereof a track forming vertically spaced rails. Such rails support a wide variety of accessories either for adjustable clamping thereto or rolling therealong.
- One such accessory is a support for a video display screen (CRT) which is mounted on rollers for free rolling movement along one of the tracks and which-includes a manual or power driven adjustment for height, angle, and position with respect to the user.

- Referring now first to Figs. 1-8, and initially to Fig. 1, there is illustrated the more basic components of the work station of the present invention. Such components comprise two spaced
legs 40 which may be in all respects identical. Each leg includes a lower square-in-section component 41 and an upper similar square-in-section component 42 which telescopes over thecomponent 41. As will hereinafter be described, a rotating screw is journaled in theupper component 42 and is in mesh with a nut secured to thelower component 41. Rotation of the screw will vertically adjust the height of the leg. - The face of each component of the
legs leg cap cover 47 is adapted to fit closely over recessedtop 48. - As seen in Fig. 1, each
leg 40 is provided with afoot 50 projecting toward the viewer and to the right, such foot being secured to the corresponding face of the bottom of theleg component 41 by suitable fasteners fitting through the screw holes 44. The end of the foot is provided with anadjustable glide 51. The foot may be covered by afoot cover 52.Screw ports 44, when not utilized, may be covered by screw covers 53. - Interconnecting the
legs outer plate 59 and aninner stiffening plate 60 which may be bent to form three horizontally extendingrectangular ribs 61. At the top and bottom the outer plate is inwardly folded to form aflange 62 and then folded again on itself or hemmed as indicated at 63. The inner plate is inwardly folded at its edges to form ashort flange 64 which fits behind the foldededge 63 of the outer plate. The two plates of each beam may be spot welded together where contiguous. - As seen more clearly in Fig. 7, the ends of each beam are rounded as indicated at 66 in the same fashion as the corners of the leg components are also rounded as seen at 67. Secured to the upper components of the legs are vertically spaced facing U-shape brackets seen at 68. The bight portion of the brackets is welded to the face of the upper component of the leg as indicated at 69 and each bracket includes spaced parallel projecting
legs cap screws 73 which secure the beams to the brackets in the manner indicated more clearly in Figs. 1 and 8. With the beams connected to the brackets in the manner indicated, thetop components 42 of each leg assembly are firmly and rigidly interconnected. When connected to the legs, the beams are slightly spaced providing anopen slot 75 which extends completely vertically therethrough. - Secured to the interior of each of the top two
rectangular ribs 61 is a horizontally extending plate in a vertical plane as seen at 76 and 77, the top and bottom horizontal andparallel edges 78 and 79 -of which form top and bottom rails, respectively. Thus the plates are secured to the beams to form tracks, and the top and bottom edges thereof form rails to accommodate either for clamping or rolling movement therealong a wide variety of accessories hereinafter described. The top and bottom edges of the plates may be rounded, beveled, or hemmed to remove rough edges and better to accommodate the accessories. In the illustrated embodiment there is approximately a 4 cm. clearance between the two rails which permits accessories to be clamped to or mounted on both rails concurrently. - Reverting now to Fig. 1 it will be seen that the top and bottom of each beam is provided with a row of horizontally elongated holes extending through both the inner and outer plates thereof, such rows being seen at 80 and 81. With such through holes in the top and bottom edges of the stiff and rigid beams, a wide variety of accessories may be mounted directly on the face of the beams to project in cantilever fashion therefrom. As hereinafter described, such accessories may include drawer units, filing units, back files, or hanging files, as well as specially designed cabinets for printers or disc readers, and surface supports.
- Referring further to Fig. 1 it will be seen that supports 83 and 84 may be secured to the
upper components 42 of thelegs screw mounting holes 44 to project in cantilever fashion in the same direction as thefeet 50. The top supports are designed to support a work top orsurface 85. Each top support includes anunderlying arm 86 and anoverlying slide 87 which are hingedly interconnected at their distal or outer ends at 88. The outer end is of course the end of the support or edge of the work surface toward the user. - The
work surface 85 is relatively thin and is primarily a sheet metal structure rigidified by a honeycomb core. Its underside at each lateral edge may be provided with a T-shape channel which fits on theslides 87. - It will be noted that the work surface is mounted on the slides for in and out sliding movement or towards and away from either the user or the
slot 75 provided by the spaced apart beams 55 and 56. Thesurface 85 may be released for such sliding movement by a spring loaded latch seen more clearly in Fig. 2 at 90 which projects through arectangular hole 91 inslides 87. - The slide as seen also in Fig. 2 is provided with a
slide surface 92 which is mounted on an underlying relatively shallow channel-shape frame 93 which includes, at its distal end, downwardly projectingears upstanding ears 97 and 98 on the end ofsupport arm 86. It is through such aligned holes that such arm and slide are hingedly interconnected byhinge pin 99. The hinge pin not only extends through the holes in the aligned ears of the arm and slide, but also through aplastic actuator housing 101. The actuator housing primarily provides a mounting for pivotingpaddle 102 for releasingcatch 90 as well assawtooth motor switch 103 controlling, for example, the motorized adjustment of the height of the leg or legs. - The actuator or
plastic switch housing 101 is a one-piece molded plastic part which includes acentral web 105 which at its inner end has a laterally projectingear 106 and an inverted L-shape wire shield 107. The ear includes ahole 108 adapted to align withhole 109 inspring 110 ofspring catch 90. Both such holes are adapted to fit over a projecting stud on the under surface of theslide 87 and may be held thereto by a suitable fastener with thespring catch 90 then projecting through thehole 91. - On the outer end of the web are laterally projecting,
semicircular blocks 112 and ll3. Each block includes near its inner end slots as seen at 114 and 115 which are separated by upstanding outer andinner ears 116 and 117, each outerear having hole 118 while each inner ear has upwardly openingslot 119. Such holes and slots are aligned and also aligned with acorresponding slot 120 in theweb 105. - The ears ll7 with the
slots 119 therein are spaced from the web and connected thereto by a bridge along the bottom providing slots orrecesses lever 102 and the sawtooth motor switch 103, respectively. Extending circularly upwardly from the bridge aretabs slots tab portion 128 oflever 102 and the saw tooth projecting portion of theswitch actuator 103, respectively. - The
slots 114 and ll5 of theactuator housing 101 accommodate thecontiguous ears position switch 129 is secured to one wall of the web as indicated and itstoggle arm 130 meshes withslot 131 on the inner end of theswitch actuator 103 when in assembled condition. - As indicated, the actuator housing is secured to the underside of the
slide 87 and of course pivots therewith. The projecting end of thesemicircular blocks work surface 85 to slide thereover when released by thespring catch 90. - In assembled condition, the
hinge pin 99, held bycap screws ear 94;ear 97; theslot 119 ofear 117;hole 137 inmotor switch actuator 103;slot 120;hole 138 inlever 102;slot 119 inear 117; ear 98;ear 95; and thehole 118 in righthand ear 116. - In this manner the arm and slide are interconnected and also the
switch actuator assembly 101 secured to the underside of the slide. The switch actuator assembly may provide at the distal end of the arm or the edge of the work surface closest to the user controls both for the height adjustment of the legs and thus all of the components supported thereby as well as for release of thework surface 85 for in and out sliding movement along theslides 87. In any event the actuator assembly presents at a position convenient to the user at least two switches or actuators at each edge of thework surface 85. It will of course occur to one skilled in the art that such convenience switches or levers provided through the actuator housing may be for a variety of purposes including concurrent vertical adjustment of both legs, individual adjustment of each leg, or adjustment of angle of the work surface or even selected accessories. - Referring now to Fig. 3 there is illustrated in section the upper end of a leg illustrating the manner in which the leg may be driven for motorized vertical adjustment or by use of a hand tool. It should be appreciated that Fig. 3 illustrates components of the present invention which may not normally be used together. As seen in Fig. 3 the
upper component 42 of theleg 40 is closed by top 48 and thecap cover 47 seen in Fig. 1 has been removed. The top 48 includes ahorizontal wall 140 and a downwardly projecting recessed interior flange 141 which fits inside thetubular component 42 of the leg.Top 140 has a projectingshoulder 142 which seats on top of thetubular component 42 of theleg 40. Centered in thehorizontal wall 140 is ahole 143 through which extends a plastic sleeve bearing 144. The plastic sleeve bearing 144 accommodates reduced diametercylindrical portion 145 of height adjusting screw 146. A roller thrust bearing 147 extends between the shoulder at the top of the screw portion and the underside of the plastic bearing. Abottom wall 149 of a chair-bracket 150 is provided with a hole through which the bearing 144 extends, such bearing being secured bywasher 152 to be held in place by the illustrated snap ring. - The screw 146 projects through a
nut 154 captured between theparallel side walls 155 ofnut retainer 156. The nut is vertically captured by top strap 157 and both the strap and nut retainer are held tohorizontal plate 159 secured to the interior of theleg component 41 by the fasteners indicated at 160. In this manner rotation of the screw in opposite directions will cause theupper component 42 of the leg to move up and down. - The upper end of the screw 146 is provided with a yet further reduced
diameter extension 162 to which is secured a bushing bytransverse pin 164. The lower end of the bushing has a cylindrical hole accommodating theextension 162 while the upper end of the bushing is provided with ahexagonal hole 165. The hexagonal hole accommodateshexagonal pin 166 which may be roll pin connected at 167 to extension shaft 168. The extension shaft extends through a flanged bushing 170 mounted inhorizontal plate 171 of the chair bracket and amiter gear 172 is mounted on top of the extension shaft. Such miter gear is in mesh with afurther miter gear 173 mounted onhorizontal cross shaft 174 which extends between the projectinghorizontal components 175 mounted on theside walls 176 of the chair bracket. The cross shaft is provided with a bushing on its end havinghexagonal opening 178. The hexagonal opening will be positioned adjacent a hole in the wall facing the viewer ofleg extension 180 in which thechair bracket 150 snugly fits. The leg extension has the same or similar configuration to thelower component 41 of the telescoping legs and provides a vertical leg extension when thecap 47 is removed and replaced by such leg extension. The leg extension, like the cap, fits on upwardly facingshoulder 181 on the top 48 with upwardly extendingflange 182 telescoping therewithin. - The
pin 164, in addition to securing thebushing 163 to the top of the screw, may also serve to securetiming belt pulley 184 to the bushing and also to the screw. Atiming belt 185 connects thepulley 184 to thepulley 186 mounted onshaft 187 extending parallel to the screw and journaled onbracket 189 which may be secured to the beam or leg. Suitable slots are provided in the leg top and/or chair bracket to accommodate thetiming belt 185. In this manner the screw may be motor driven through suitable transmissions and one or more motors as hereinafter described, all below the level of the work surface. - It should be appreciated that not all of the components seen in Fig. 3 may necessarily be used together. For example, the chair bracket,
leg extension 180 as well as the extension shaft and thegears bushing 163 with thehexagonal hole 165 being exposed upon removal of thecap 47. In such situation manual adjustment of the screw is obtained by simply inserting a hexagonal tool in thehexagonal hole 165, such tool being, for example, an Allen wrench. Of course with the leg extension the hexagonal tool would be inserted through the hole in the facing wall thereof. - Also, it will be appreciated that the motor drive is optional and the pulleys and timing belt may be employed only in the event such motor drive is utilized, or in the event of single source manual adjustment. Even with the motor drive, manual adjustment may still be made with a suitable hexagonal tool placed in the
top bushing 163. It will also be appreciated that the projecting end of theshaft 187 may be provided with a hexagonal recess also to receive an adjustment tool. - Referring now to Figs. 4 and 5, there is illustrated a work station assembled. As illustrated in Fig. 4 as well as in Fig. 1, directly beneath the
work surface 85 extending between thearms 86 is awiring tray 195. The wiring tray comprises a series of transverse fairly large channels seen at 196, 197 and 198. Such channels are open at their ends and communicate with horizontal slot or opening 200 which is perhaps seen more clearly in Fig. 2. Theslot 200 extends between the arm and the overlying slide and permits lateral access through the arm from the wiring tray to lateral extensions or components. The rearmost channel 196 may be provided with a convenience outlet seen at 201. The convenience outlet may be prewired for light, power, communications or interfaces for the various components of computers such as the keyboard, screen, disc reader or printer. - Also as seen in Fig. 4 there is illustrated a two motor drive seen schematically at 203 and 204. Each motor includes a transmission seen at 205 and 206, respectively, driving the
shaft 187 on which is situated thepulley 186. Such shafts at each side of the table or work station may be interconnected through miter gearing shown at 207 and 208 and line shaft 209. With the line shaft the screws in each leg would rotate in synchronism. Also with the line shaft asingle switch 103 may control both motors. It will be appreciated that leveling can be accomplished by utilizing theadjustable glide 51. It will also be appreciated that with the line shaft a single somewhat more powerful motor may be employed for vertical adjustment of both legs. - Also, as indicated in Fig. 4, suitable limit switches seen at 211 in each leg or on the outside of each leg will not permit rotation of the motor in a given direction beyond set limits. The motor and transmission may be provided in a housing indicated at 212 which extends to the rear of the beam and may be fastened to the legs. Such housing has the appearance of a short work surface and may be constructed with a pivoting slide so that the top surface may be pivoted upwardly or slid rearwardly to expose the motor, transmission and shafts. Such housing with or without the motors and transmissions is seen in end elevation in Figs. 27, 28 and 37, for example.
- The back edge of the tray as indicated at 214 and 215 may be provided with one or more wire managers which are simply plastic clips holding wires separated. The wires may extend downwardly over the rear edge of the tray indicated at 216 or they may extend over the top of the beams beneath a wire and pulley cover seen at 217.
- As seen more clearly in Fig. 5, wiring to the convenience outlet may be provided through tubular wire manager 220 which may extend upwardly on the interior of each leg. Below the wire manager coil cord indicated at 221 may be provided with the cord extending through
wire clip 222. Coil cord indicated at 223 may be provided from the convenience outlet to the video support as well as to other accessories such as task lights or telephone pads. It will also be appreciated that the coil cord 221 may be encased in a similar wire manager secured to the lowertelescoping leg component 41 and telescoping with the wire manager 220. - Referring now to Fig. 6 there is illustrated a more fully assembled work station showing the
work surface 85 in front and the somewhatshorter housing 212 at the back of the work station with theopen slot 75 therebetween. It is noted that thecaps 47 at the tops of thelegs 40 are flush with both surfaces. Projecting upwardly through the slot are certain accessories such asvideo screen support 225, aphone pad 226 and one form of task light 227. The video screen support supportsvideo screen 228. In the illustrated form, the video screen support may be power operated up and down by thelever 229 and the angle of the video screen support may be adjusted byknob 230. Thework surface 85 supports a keyboard indicated at 231. - Supported at each side of the
work surface 85 andhousing 212 arecabinets leg 40 and also to the projecting arms supporting both thework surface 85 as well as thehousing 212. As an example, thecabinet 233 may contain a built-indisc reader 236 at its front while thecabinet 234 includes anopening 237 in which is mounted aprinter 238. The front of thecabinet 234 may also include one or more drawers indicated at 240. - The
cabinet 233 includes atop surface 241 which constitutes an extension of the.work surface 85. Thecabinet 234 also includes asurface 242 which is at the same plane as thesurfaces - Height adjustment, if the work station is motor driven, may be obtained through the
actuator housing 101 and the appropriate saw tooth motor switch or switches. The entire work surface as well as the attachedcabinets upper support leg 180, also performed by inserting a hex tool insocket 178. It will be appreciated that the accessories illustrated may be positioned at any desired location along theslot 75 in the manner hereinafter described. - Referring first to Figs. 9, 10, 11 and 12, there is illustrated a video screen support which includes a carriage shown generally at 250 which includes primarily a flanged
vertical plate 251 with stud mounted V-shape rollers 252 mounted at each corner thereof. The studs of the lower two rollers are threaded and extend through vertically elongated holes 253 so that the lower rollers may be moved slightly up and down when nut 254 on the side of theplate 251 opposite the rollers is loosened. In this manner thecarriage 250 may be mounted on the vertical rail edges 78 and 79 of the plate or track 77 of thebeam 56. - The top and
bottom flanges 256 of the carriage plate assist in securing to the plate a verticaltubular column 257. The tubular column projects somewhat above and below the plate and includes at its lower end a fitting 258, to the interior of which is secured a somewhat smaller upwardly projectinginterior column 259, on top of which secured against rotation is a shoulderednut 260. The inner and outer columns as well as thenut 260 are vertically fixed. - Extending downwardly through the nut is a
screw 261. The upper end of the screw is provided with a fitting 262 securing the screw for rotation withshaft 263 which is mounted insleeve bearing 264 andball bearing 265 inside vertically movabletubular column 266. The lower end of thetubular column 266 is provided with a slidingbearing 267 fitting within thecolumn 257.Such column 257 at its upper end also is provided with a fixedbearing 268 in which the verticallymovable column 266 slides. - The
column 266 is thus designed to move not only up and down but also to pivot about its vertical axis. Mounted on top of thecolumn 266 is a hollow gooseneck or offset 270 which includes on its distal end atubular post 271, the axis of which is parallel to the axis of thecolumn 266. - Mounted on top of the
post 271 is atubular column 272 which is part of the video terminal support tray shown generally at 273. - Referring now additionally to Fig. 11 it will be seen that the
column 272 is in the center of atransverse bridge member 275 interconnecting thesides pivots upstanding face plate 282 on which manual adjustment knobs 283 and 284 are mounted. Such adjustment knobs may be provided with diametral slots at one end of which is pivotally mounted a crank handle. In a recessed position the crank handle is flush with the knob. In an operative position it is pivoted 180° and may be employed to rotate the knob. - The
side frame members top flanges screen support members arrows 292 in Fig. ll by loosening and then tighteningfasteners 294 which are threaded insleeve nuts 295 secured to the transverse support members. Each fastener includes aclamp washer 296 underlying theflanges - The
knob 283 seen in Fig. 11 is secured to ashaft 300 mounted in theface plate 282 against axial movement but for rotation as indicated at 301. The shaft on its end interior of the face plate is threaded as indicated at 302, such threaded shaft being received in blind threadedhole 303 ofrod 304. The opposite end of the rod is pivoted at 305 to thebridge 275 significantly above its pivot point to the frame as seen more clearly in Fig. 10. Thus rotation of theknob 283 will cause the video terminal tray to pivot about the horizontal axis of thepivots - The
other knob 284 is connected to shaft 307 which is journaled not only in the face plate as indicated at 308, but also in hub 309 secured to the interior of theside frame 278. The inner projecting end of the shaft 307 has secured thereto an end fitting 310 of flexible shaft 311 which extends downwardly through thecolumn 271 of thegooseneck 270. The opposite end of the flexible shaft 311 is secured by similar fitting 312 to the top ofshaft 263 seen in Fig. 10. In this manner, rotation of theknob 284 will cause thescrew 261 to turn raising or lowering thetray 273 with respect to the mountingcarriage 250. - It will now be seen that the mounting tray for the video terminal may be moved horizontally along the
track 77 by means of the roller carriage. It may also be moved up and down by manual rotation of theknob 284. It may also be moved about the vertical axis of thecolumn 266 by the amount of the throw of thegooseneck 270 whether this be to the side or fore and aft. It may also be pivoted about the vertical axis of thecolumn 271. Its horizontal tilt or inclination may also be adjusted byknob 283 about the horizontal axis ofpivots legs 40. - Referring now to Fig. 12 it will be seen that in modified form the height adjustment may be powered or motor controlled. In such figure there is provided a
motor 315 operative to rotate thescrew 316 which is vertically fixed. The screw extends through anut 317 mounted on the lower end of verticallymovable column 318. As can be seen, theupstanding screw 316 is journaled at 320 at the lower end of the fixed column driven bymotor 315 throughtiming belt 321 transmission extending betweenmotor pulley 322 and screw pulley 323. The motor as well as the pulleys are mounted onplate 324 extending from the somewhat elongated plate of the carriage. A limit switch mechanism indicated at 325 may be provided to indicate the limits of vertical motor driven adjustment. Acapacitor unit 326 for themotor 315 may be provided mounted on the plate of the carriage. In any event it will be appreciated that the height adjustment of the video terminal tray may be motor driven rather than manually driven as indicated by the embodiment of Fig. 12. Again, the carriage of the motor driven height adjustment for the video terminal may be mounted on the tracks of the beam in the same manner. Control of the motor driven height adjustment may be as indicated in Fig. 6. - Referring now to Figs. 13-16 there is illustrated a universal mounting post shown generally at 330 which may be clamped at any position horizontally along either rail of either beam and which supports individually or concurrently a wide variety of accessories. Mounting
post 330 comprises a vertically extending base plate 331 which includes at its bottom a rearwardly extendingflange 332 and at its top a forwardly extending inverted V-shape flange 333. The lower rear surface of theflange 332 is provided with apiano hinge 334 which pivotally secureshinge plate 335 to the bottom of the mounting post. The forward edge of thehinge plate 335 is provided with an upwardly opening V-shape configuration seen at 336. As can be seen more clearly in Fig. 13 the V-shape configurations - Secured to the back of the plate 331 is a channel from the upper end of which projects
tubular post 339. The post, channel and plate may be welded together. The top of thepost 339 is provided with atab 340 designed to mate with a forked extension on an interfitting part or a washer tab. - Also mounted on the
channel 338 is apivot bracket 342 to which is pivoted alever 343. The lever may move from the full line position seen in Fig. 14 to the phantom line position indicated at 344 and includes astop projection 345 which limits the clockwise movement of the lever to such phantom line position. The phantom line position is the unlocked position while the full line position is the locked position. Pivoted to the lever at 347 is apivot link plate 348 to which is securedrod 349. Therod 349 extends through a hole inflange 332 and is provided with atransverse roll pin 350 between theflange 332 and theplate 335. The rod extends through a hole in thehinge plate 335 and below the hinge plate there is atapered spacer 351 held in position by lock nuts 352. - As can be seen more clearly in Fig. 14, the
pivot 347 is slightly over center of thepivot 353 for thelever 343 in the toggle locked position of the lever. In such position the mounting post will be firmly clamped to therail 77. When the lever is swung to its open orphantom line position 344, the mounting post may be released. - Referring now to Fig. 16 there are illustrated some variations in accessories which may be supported through the mounting post. Reading upwardly from the top of the post it will be seen that there is provided a
stop washer 355. The stop washer has a downwardly projectingtab 356 and an upwardly projectingtab 357, such tabs being spaced 90° apart. The downwardly projecting tab is designed to engage thetab 340 on top of the mounting post while the upwardly projecting tab may engageswing arm 359. The swing arm at its proximal end is provided with a two-part tubular pintle 360 which includes a downwardly projectingsmaller diameter tube 361 designed to fit closely within the top of thepost 339. The upper end of the pintle is the same diameter as the post and includes asocket 362 which is the same internal diameter as the post. When not in use, the socket may be closed by atrim cap 363. The outer end of the swing arm is provided with atubular socket 364 which has the same internal diameter as thesocket 362 and of course thepost 339. On the end of theswing arm 359 there is positioned anotherstop washer 355 and anidentical swing arm 359. Again atrim cap 363 may be employed in thesocket 362 of the second swing arm. On the outer end afurther stop washer 355 is positioned and reading from left to right, one of the noted accessories may be positioned in the socket of the second swing arm, such illustrated accessories being acopy reader 368, or either ofphone holder pads copy reader 368 may be provided with an optional plug-in light at its top indicated at 371. It may also have a spring ratchet height adjustment as seen at 372. As indicated, each of the accessories is provided with a two-part post seen generally at 373 with the lower portion being of reduced diameter indicated at 374 and again designed closely to fit within thesockets - In the upper righthand corner of Fig. 16 there is illustrated another type of
phone holder 375 and perforatedmetal letter trays spacer 379. The spacer is simply the same configuration as the post but is not secured to an accessory. The height of the upper or larger diameter portion of the spacer may vary. In any event, the lower or smaller diameter portion is designed to fit in the open socket at the top of the post of theletter tray 376. It will be appreciated that more than one letter tray may be stacked in the manner indicated. - To keep the letter trays or other accessories from rotating where such rotation is not desirable, the lower end of the larger diameter of the
post 378 may be provided with a downwardly projecting two-prong fork 380 with the tines being designed to fit one on each side of thetab 340 at the top of the post. Tabs similar to thetab 340 may be provided at the top of thepost 378 as indicated at 381 as well as at the top of thespacer 379. The spacer may also be provided with a fork indicated at 382 and also a tab indicated at 383, the tab cooperating with the fork on the post ofletter tray 377. Thefork 382 on the spacer of course cooperates with thetab 381 on thepost 378. In this manner the letter trays may be mounted on the top of thepost 339 and held against rotation. - It will be appreciated that the configuration of the telephone holders depends entirely upon the configuration of the telephone involved. It will also be appreciated that any of the accessories illustrated may be mounted on any desirable open socket, whether it be the top of the
post 339, thesocket 362 at the inner end of the swing arm, or thesocket 364 at the outer end. With the employment of two swing arms, the position of the accessory can manually be adjusted over a wide area for the convenience of the vision and reach of the user. It will also be appreciated that spacer columns like those illustrated, with or without anti-rotation devices, may be inserted where desired to obtain the desired height adjustment. - Referring now to Fig. 17 there is illustrated in greater
detail letter tray 377. The letter tray includes a perforated one piece side wall andfloor 385 secured to foldededge bulkhead 386. The edges of the walls and floor may be covered by a plastic bead seen at 387. Secured to the bulkhead is a two-part post 388 which may be the same as the posts illustrated mounted on the letter trays in Fig. 16. The post includes a lowersmaller diameter portion 389 which is adapted to plug into the top ofspacer 379. As indicated, the tubular post is provided with atop tab 390 and a lower projectingfork 391, the latter cooperating with thetab 383 on thespacer 379. The top of thepost 388 may be closed by a trim cap, if not further used. - The mounting post assembly may also support task lamps with the wiring for the lamps extending through the posts, the spacer and through the
tubular post 339 to a transformer which may be conveniently mounted on the bottom of the mountingpost assembly 330. Wiring for the task light 371 on top of the copy reader may also extend through the posts, swing arms, etc. to its convenient transformer mounted on the plate of the mountingpost assembly 330. - Referring now to Figs. 18 and 19 there is illustrated a form of task light provided with its own roller carriage which may be mounted directly on the tracks of the beams. Such task light shown generally at 400 includes a
carriage plate 401 having atop flange 402. Top V-shape rollers Rollers levers slots 414 and 415 in the lower end oflever arm 416. The lever arm is mounted for vertical movement on the front of theplate 401 and is held in position byalignment tabs 417. Above thealignment tabs 417 the lever arm is adapted to spring from the plane of the plate as indicated at 418. As the lever arm projects through an appropriate notch in thetop flange 402, it becomes more narrow as indicated at 419 and on each side of the more narrow portion there are provided projectinglocking tabs 420 and 421 designed to cooperate with the underside of the flange in a locking position but to be released therefrom if the lever arm is sprung from its locking position or to the right above the alignment tabs as seen in Fig. 19. This then releases the lever arm for vertical upward movement. Such vertical upward movement will then cause thelevers bottom rollers rail plate 77. The carriage is initially positioned by placing the top rollers on the upper rail and with the bottom rollers open, they are then aligned with the bottom rail, the lever arm is then pushed downwardly until it springs into its locking position with the tabs beneath the flange. In this manner the carriage is then mounted on the rail or track for rolling movement therealong. The carriage may be removed from the track simply by releasing the lever arm and pulling it upwardly. - It is noted that the bottom corners of the
plate 401 are cut away as indicated at 425 and 426 and a bottom flange to the plate is provided at 427. To this plate there is secured atransformer 428. - Secured to the back of the
plate 401 are two parallelupstanding tubes disconnect lever 416 above theflange 402 may be offset as indicated at 432 to fit between the tubes. The tubes may be secured to the back plate as by welding. The top of the tubes are interconnected by aconnector 434 which also provides a mounting for a fixed horizontally projectinginner tube 435. The opposite end of the connector is closed with a removableplastic cap 436. Mounted for telescoping movement over theinner tube 435 is anouter tube 437. The two tubes may have suitable plastic bearings interposed therebetween permitting the light fixture shown generally at 438 secured to the outer tube to move to the right and left as seen in Fig. 19 by such telescoping movement and also to pivot toward or away from the viewer as seen in Fig. 19 or to the right or left as seen in Fig. 18, all about the axis of the concentric telescoping tubes. Suitable rotational and longitudinal stops may be provided. Theinner tube 437 is provided with aknob 440 for operating rotary on-off switch 441. - The fixture includes a generally

- Fig. 28 illustrates a situation for a standing user with the
work surface 85 significantly elevated. Again the video terminal, copy holder and keyboard are positioned within convenient eye range of the user. - Fig. 29 illustrates a wheelchair adjustment. If the user is in a wheelchair indicated generally at 506 the work surface may be significantly raised while the
video terminal 492 is lowered. - Fig. 30 illustrates a multiple use work station having
work surfaces 85 projecting essentially the same distance on each side of thelegs 40 with feet corresponding. The video terminal may be an integrated monitor incorporating both the screen and keyboard as seen at 508. The terminal may be mounted on a lazy susantype rotating unit 509 so that it may be used from either side of the work station. Again, height adjustment for the user is readily available. - In Fig. 31 there is illustrated a rather basic variation or standard work station with the only accessory provided being the adjustable track mounted task light such as seen at 227 in Fig. 6.
- In Fig. 32 there may be added a
high storage unit 460 mounted onleg extensions 180. Also, there may be provided a sub-worksurface drawer unit 512 which may be supported in cantilever fashion from the beam in addition to the arm orarms 86. - In Fig. 33 there is illustrated a standard filing station which may include track mounted in and out files or letter trays seen at 514 which may be mounted directly on a mounting
