Abstract
A climbing device is configured to have a locking mechanism operative to allow the handle and the footplate of the climbing device to pivot to and engage a portion of building structure in a position, in which further displacement of the footplate and handle relative to one another is arrested to lock the portion between the jaws of the device.
Claims18
A climbing device for attachment to a portion of a structure comprising:
- a frame;
- opposing jaws slideable relative to one another along the frame to engage a portion of the structure therebetween;
- a footplate mounted to the frame and configured to support a load;
- a handle mounted to the frame and coupled to the footplate, the footplate and the handle being displaceable relative to one another in response to an external force applied to the handle between a position in which the climbing device is capable of sliding relative to the structure upon engagement of the portion thereof by the jaws, and a position in which the structure is locked between the jaws upon ceasing the external force;
- and
- a locking mechanism located between the footplate and the handle and configured to prevent displacement thereof relative to one another upon ceasing the external force the locking mechanism includes a toothed rack and a pawl selectively meshing with the toothed rack upon removing the external force from the handle to ensure locking of the portion of the structure between the jaws, and a flexible arm pivotally coupled to the handle and operative to lift the pawl off the toothed rack to release the handle relative to the footplate in response to the external force applied to the handle.

A climbing device for attachment to a portion of a structure comprising:
- opposing jaws slideable relative to one another;
- a footplate mounted pivotally to one of the jaws and configured to support a load;
- a handle mounted pivotally to the one jaw and coupled to the footplate;
- a reciprocating piston attached to the footplate and the handle and movable linearly in response to pivoting one of the handle and the footplate from a first position, in which a portion of the structure is placed between the opposing jaws, and a second position, in which the portion of the structure is secured between the other jaw and the reciprocating piston;
- and
- a locking mechanism located between the footplate and the handle and configured to prevent displacement thereof relative to one another in the second position thereof, to which the piston moves upon ceasing an external force applied to the handle, the locking mechanism including a toothed rack and a pawl selectively meshing with the toothed rack in the second position, and a flexible arm pivotally coupled to the handle and operative to lift the pawl off the toothed rack to release the handle relative to the footplate upon applying the external force to the handle.
