Description
- 1. Field of the Invention
- The present invention relates to a rope climbing device, and more particularly to a rope climbing device including a resilient or spring-biased engaging device for selectively engaging with the rope and for facilitating the movement of the rope climbing device along the rope and for preventing the rope climbing device from sliding or moving downwardly relative to or along the rope inadvertently
- 2. Description of the Prior Art
- Typical rope climbing devices are provided for use in climbing up or down a taut rope and comprise closely similar handle and pedal units each including two pivotally connected members between which the rope passes and by which the rope may be alternatively clamped and released through suitable manipulation of the user.
- For example, U.S. Pat. No. 3,938,620 to Nothiger discloses one of the typical rope climbers also comprising a handle unit and a pedal unit each including two pivotally connected members for engaging with the taut rope and for alternatively clamping and releasing the taut rope, and thus for allowing the handle and pedal units to climb up or down the taut rope.
- However, the two hands and/or the two feet of the user should be moved up or down along the taut rope simultaneously and may not be moved separately. In addition, once the two pivotally connected members of either the handle unit or the pedal unit are separated from each other or disengaged from the taut rope, no other retaining devices may attach or couple the handle and pedal units to the taut rope such that the handle and pedal units may slip downwardly along the taut rope inadvertently.
- U.S. Pat. No. 4,928,791 to Hong discloses another typical rope climber comprising two grooved wheels having the outer circumferences in close contact and capable of rotating in opposite directions for sliding up and down a cable or rope.
- However, similarly, the two hands and/or the two feet of the user also should be moved up or down along the taut rope simultaneously and may not be moved separately. In addition, once the two grooved wheels are separated from each other or disengaged from the cable or rope, no other retaining devices may attach or couple the rope climber to the cable or rope such that the rope climber also may slip downwardly along the cable or rope inadvertently.
- U.S. Pat. No. 5,029,669 to Lew et al. discloses a further typical rope climbing and sliding device comprising a handle assembly having a pair of handles, and a stirrup assembly having two foot-holds for sliding up and down a cable or rope, and a harness depending from the handle assembly for supporting the users.
- However, similarly, the two hands and/or the two feet of the user also should be moved up or down along the cable or rope simultaneously and may not be moved separately. In addition, once the handles or the foot-holds are separated from each other or disengaged from the cable or rope, no other retaining devices may attach or couple the rope climbing and sliding device to the cable or rope such that the rope climbing and sliding device also may slip downwardly along the cable or rope inadvertently.
- U.S. Pat. No. 6,286,625 to AstvasaDoorian discloses a still further typical rope climbing device that attaches to a person's feet for assisting with ascending or descending along a rope, comprising a frame including a housing and a base member coupled together, and a slide member partially enclosed in the housing and slidable along the frame and having hooks for engaging with a rope with two pivoting cams, and the downward force on the base member resulting from the user's weight moves the slide member upward relative to the frame.
- However, when the hooks and/or the pivoting cams are separated from each other or disengaged from the cable or rope, no other retaining devices may attach or couple the rope climbing device to the rope such that the rope climbing device also may slip downwardly along the rope inadvertently.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional rope climbing devices.
- The primary objective of the present invention is to provide a rope climbing device including a resilient or spring-biased engaging device for selectively engaging with the rope and for facilitating the movement of the rope climbing device along the rope and for preventing the rope climbing device from sliding downwardly relative to or along the rope inadvertently.

- The pressing member is pivotally coupled to the arm with a rod, and the housing includes a panel having a curved slot formed therein for slidably receiving the rod and for limiting the arm and the pressing member to rotate relative to the panel of the housing. The panel is pivotally coupled to the housing with a pivot axle for supporting the spindle.
- The lever includes a curved groove formed therein, and a shaft is attached to the housing and slidably engaged in the curved groove of the lever for limiting the shaft to slide along the curved groove of the lever and thus for limiting the lever to rotate relative to the housing.
- A frame may further be provided and attached to the housing for supporting the spindle. A fastener may further be provided and engaged with the housing and the frame for securing the frame to the housing.
- A latch may further be provided and pivotally coupled to the frame with a pivot pin, and a spring member is attached to the frame and engaged with the latch for biasing the latch to engage with the fastener in order to lock the fastener to the frame and for preventing the fastener from being disengaged from the frame.
