The claws retract when they come in contact with a cross beam and re-extend in the intervals between. They are arranged to ensure that enough craws are extended at any given time to support the object being removed.

  • Patent number: 8230631
    Abstract: An adjustable display frame has first and second U-shaped frame elements having aligned free end surfaces that abut to form a small display frame and are separated by first and second inert elements urged by a spring to provide a large display frame. Each U-shaped frame element has a pair of longitudinal slots which receive heads of headed studs projecting from a base disposed behind the frame elements, wherein the frame elements are secured to the base and are capable of sliding on the base from a first position, to provide the small frame, to a second position so as to provide the large frame. The inserts are slidable on the base inboard of the U-shaped frame elements and are spring biased so as to move between the free ends of the U-shaped frame elements when the U-shaped frame elements are separated by being pulled apart. Stops are provided for arresting motion of the inserts to align the inserts with the free ends of the U-shaped frame elements after the inserts have been pushed outwardly by the spring.
