ABSTRACT:
A standard and a boom extending from the standard are connected by a mechanism to permit the boom to be pivoted between an upright, locked position and a lowered, collapsed position. A connecting device is employed to attach the boom mechanism to the standard which permits heightwise adjustment of the boom on the standard. The connecting mechanism includes a member having an L-shaped slot which receives a pair of pins extending from the boom. The length of one of the legs of the L-shaped slot is at least equal to the spacing between the pins and the other leg of the slot is longer than the spacing between the pins to lock the device in position when the pins are disposed in the other leg of the slot. The invention is disclosed as being used with a space divider such as a curtain which can be hung from the boom.
