  • Patent number: 7347335
    Abstract: A spring-driven pusher assembly of a merchandise dispenser in which the spring is carried entirely on the pusher assembly behind the articles being dispensed to thereby eliminate any interference problems with RF signals or the like used for purposes of determining inventories and the like. Preferably, the spring is a spiral spring that rotates a drive wheel when the spring uncoils. The drive wheel cooperatively engages a guide track on the base of the dispenser, and the rotation of the drive wheel causes the pusher assembly to advance along the guide track toward the dispensing end of the dispenser.

  • Patent number: 6464089
    Abstract: A spring-driven pusher device for a forward, side, top, or up feeding merchandise dispenser having an adjustment mechanism for setting a desired pushing force. The adjustment mechanism is utilized to increase and/or reduce the tension of the windings of the coiled end of a spring or strip of coiled metal carried on the pusher device. The tension in the windings is increased if greater pushing force is desired, or decreased, if less pushing force is desired. Since the desired pushing force can be set, the same spring-driven pusher device can be utilized to feed various different products, regardless of size, shape, weight or surface texture.
