A display stand for merchandise such as clothing or the like includes a base supporting a telescopic stand structure formed from a pair of telescopic tubular members. The upper tubular member has an inner end portion including an angled cam surface thereon which receives a cam member between the cam surface and an adjacent inner wall of the lower or outer tubular member. A threaded rod is secured to the cam and extends through the upper tubular member to an upper threaded free end on which a nut is threadably received. Rotation of the nut causes the cam to wedge between the inclined surface of the inner tubular member and the inner adjacent surface of the outer tubular member, to lock the telescopic members in position. |
