Abstract
A strut construction having outer and inner telescoping strut members capable of relative extending and collapsing movements. The outer strut member has a socket for a locking ball which is captive but moveable therein. A release collar is captive and slidable on the outer strut member between locking and release positions. The release collar has spaced-apart shallow and deep internal pockets for respectively receiving, depending on its locking or releasing position, portions of the captive ball of the outer strut member The inner strut member has a shoulder means which provides shallow and deep pockets to respectively receive other portions of the captive ball. The captive ball, socket of the outer strut member, and the shoulder means restrict movement of the release collar and restrict full telescoping collapsing movement of the strut members when the release collar is in its locking position wherein portions of the ball occupy the shallow pockets of the collar and shoulder means, and alternatively enable full telescoping collapsing movement of the strut members to be effected when the release collar is in its releasing position and portions of the ball occupy the deep pocket of …
