  • Patent number: 6769552
    Abstract: A product pusher device comprising an elongated guide track and a pusher sled slidably guided along the track for urging product packages forwardly on a display shelf. The pusher sled incorporates a housing for containing a coiled strip spring element. The end extremity of the spring is anchored at the forward end of the guide track, and t he coiled body spring is confined within the housing at the back of the sled. By constructing the sled housing with an open bottom, assembly is greatly facilitated by allowing the spring to be anchored on the guide track independently of the sled and thereafter allowing the sled to be lowered over the coiled body of the spring and pressed downward to be snapped into assembled position on the guide track.

  • Patent number: 5779065
    Abstract: A novel method and apparatus is disclosed for the production of single plane ladder-type rack strip material in which wire cross bar elements are Tee-welded to the inside surface portions of opposed, parallel side elements formed of similar wire material. The welding procedure involves contacting the cross bar element centrally with an electrode of a first polarity and contacting the wire side elements on opposite sides with electrodes of a second polarity. During the welding operation, current flows substantially equally from the first electrode in opposite directions through the opposite weld interfaces to the opposed second electrodes. By observing physical symmetry in the electrical supply at opposite sides, equalization of current flow is optimized so that the emerging rack strip product is flat and straight, suitable for commercial marketing.
