  • Patent number: 4329800
    Abstract: A lightweight display device capable of vertical adjustment to desired height having a display frame attached to one end of a rod whose other end is formed with a pair of resilient arms having a plurality of teeth for the outer surface. The rod is positioned for ratchet-like vertical movement within a hollow tube having a threaded inner surface which engages with the teeth. The frame can be raised or lowered, along the length of the rod, by extending a vertical force thereto sufficient to deflect the arms of the rod away from the threads of the tube. When the vertical force is removed, the teeth re-engage with the threads to support the display frame at the desired height.
