Rope-activated device for remotely tying up and untying

摘要

The mechanism has a spring mechanism connecting a movable frame (d) and an assembly on which the mechanism is placed. The spring mechanism transmits a force on the frame to maintain the frame in an unhooked position. A device varies a position of the frame based on the assembly, where the device is controlled either by the action of tension or release of a rope (h) at a preset load, or by the control and handling without using the rope.
