ABSTRACT:
A stand with collapsible legs. The legs are held to the stand by a disk member held within a pair of ears. One of the ears has a toothed opening, and the disk member includes a toothed opening. A gear member may be moved to a locked position where the gear contacts both the toothed portion of the disk member and the toothed portion of one of the ears which locks the disk in a fixed position. When the gear member is moved out of contact with the disk member, the disk member can then move freely with respect to the pair of ears. This permits the legs to be placed in numerous locked positions. Preferably, an outwardly extending tab allows the legs to be moved into a preferred position for locking.
