  • Patent number: 4991725
    Abstract: A compact storage system, mountable for operation on a flat base platform, includes at least one guide rail having a roof and two legs depending from the roof thereby defining an inverted, generally U-shaped continuous channel. The guide rail is mounted in spaced generally mutually parallel relation to the base platform with its legs projecting toward the base platform so that the channel opens downwardly. The compact storage system further includes at least one movable storage unit that is supported for translational movement on the base platform. One or more guide rollers are mounted on the storage unit to be received in the channel of the guide rail with the guide roller being formed to engage either one of the legs of the rail for movement relative thereto. Accordingly, translational movement of the storage unit is confined to a path defined by the guide rail.

  • Patent number: 4509805
    Abstract: An enclosed shelving having a top shelf supported above a bottom shelf with each of the shelves including a peripheral lip, the enclosure having an open wire construction including side and rear panels provided with retaining fingers extending at the upper and lower ends thereof to engage the peripheral lip of the shelves, thereby retaining the panels in place. The fingers are offset with respect to the panels, with the extent of offset of the fingers alternating between a greater and lesser degree of offset to thereby straddle the peripheral shelf lip and retain the panels in place. A pair of front door panels are hinged to the side panels and are provided with a latching mechanism whereby the enclosed shelving can be used for security purposes.
