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