ABSTRACT:
An adjustable device that provides a secure anchor in a crevice or other irregularity. The anchor may be used to assist rock climbers, rescue groups, military personnel, construction workers, etc. The device is comprised of a spring loaded sleeve mounted on a first end of a threaded shaft and limited in its movement on the shaft by a pin and slot arrangement. The sleeve provides a means for adjusting the length of the device. A first locking means releasably secures the sleeve in a retracted position, and a second locking means secures the sleeve at the desired extended position. A lever assembly is provided at the second end of the device in such a manner that a force applied to an attachment point of the assembly will be translated along the longitudinal axis of the device.
