Abstract: A shelf or hanger mounting bracket which comprises an inner bracket body having one end provided with projections configured for locking engagement with vertically extending slits in a wall-mounted upright mounting rail and an ornamental outer sleeve comprising a locking system enabling the sleeve to be continuously adjustable over a range of positions so that it can be adjusted to lie flush with the mounting wall. The locking system employs a latching member pivotally mounted on the forward end of the inner bracket body having a locking end slantingly engaging the confronting interior wall surface of the sleeve so that forward retracting movement of the sleeve cannot occur as long as the locking end is held in contact with this sleeve surface. Slipping rearward movement towards the wall readily occurs.

Abstract: A pair of vertical telescoping members are progressively lockable into any relative position to vary the overall length thereof by special locking hardware mounted on the inner member where it is not visible. The hardware includes a locking member movable in part by inertial forces between a released or unlocking position and a locking position where it forms a one way slip clutch with the inner surface of the outer member which permits the inner member to be raised which then preferably shifts the locking member into a release position. The inner member is moved further up or down to its desired position. Whenever the inner member is released, it is preferred that gravity will cause the inner member to move suddenly downwardly a small distance quickly to cause the locking portion of this member to move to its locking position.
