ABSTRACT:
A gas spring comprising a cylinder, a rod slidably extending from the cylinder, and a novel locking mechanism. The mechanism comprises first and second axially contiguous recesses in the circumference of the rod, a locking member normally located in the first recess and snappingly and rockingly movable between two recesses, and axially spaced first and second actuating members cooperating with the locking member. The first actuating member comprises an engaging portion and a releasing portion being circumferentially spaced therefrom. The releasing portion acts to displace the locking member to the second recess. The second actuating member comprises an engaging portion for locking the rod and also for displacing the locking member to the first recess, and axially and circumferentially inclined guide walls for circumferentially displacing the locking member thereby guiding the same between the releasing portion and engaging portions in response to the movement of the rod.
