Abstract
A releasable gripping or locking device having a body part for sliding cooperation with a rope to be releasably gripped or locked with respect to the body part. A gripping or locking member is movably mounted on the body part for movement between a free condition and a gripping or locking condition in which loading applied to the device is borne by the gripping or looking member. A control member is provided for controlling movement of the gripping or locking position. The control member includes telescoping components having interengageable latching elements which are actuated by relative movement between the device and the rope. The latching elements are adapted to be automatically engaged in a latched condition when these parts are moved relative to one another in a first direction by a predetermined amount and are brought automatically into an unlatched condition on a predetermined amount of relative movement therebetween from the latched condition in the first direction, allowing subsequent free relative movement of the telescoping components. The free, and gripping or locking, conditions of the gripping or locking member correspond respectively with the latched and unlatched conditions of the control member.
