Abstract

An expansion stay capable of locking, at a prescribed aligned position, the inner arm (12) and the outer arm (14) of a stay body (16) having the inner arm (12) and the outer arm (14) to the inner arm is slidably fitted, comprising a lock member (26) having a lockingly engaged part (24) pivotally supported on the inner arm and engaged with the lock hole (22) of the outer arm. The lock member is energized so that the lockingly engaged part is engaged with the lock hole when an extensible arm (10) is extended, the lock hole is set to such a dimension that the locking engagement part can be displaced in an arm extending direction, and the lockingly engaged part comprises a hook (24F) energized to be locked to the edge (22E1) of the lock hole. When the locking engagement part is unlocked, the hook is disengaged from the edge of the lock hole by displacing the inner arm. In the expansion stay (10), since the hook (24F) is engaged with the edge (22E1) of the lock hole (22), the locked state of the lock member (26) can be effectively prevented from being inadvertently released.

Description

technical field [0001] The present invention relates to a telescoping brace used for various swinging members such as a pivotable cover that supports a case in a predetermined open position, and more particularly to a telescoping brace that improves the locking state of a locking member that locks The components lock the inner and outer arms that are slidably fitted to each other at predetermined telescopic positions. Background technique [0002] This telescopic brace generally has: a brace main body, including an inner arm (first arm) and an outer arm (second arm) for the inner arm to slide and fit freely; a locking mechanism, which locks the brace at a predetermined overlapping position The inner and outer arms of the support body, the locking mechanism is composed of a locking part pivotally supported by the inner arm and having a locking snap-in part, the locking snap-in part snaps into the locking hole of the outer arm, and locks at a predetermined position when the in...
