  • Patent number: 4778229
    Abstract: A latch for latching a folding shelf having compartments to a cabinet having a pivotal cover is disclosed. A rectangular shelf stop downwardly projects from the transverse inner edge of the shelf and has a latch stop projecting forwardly of the shelf stop. The latch is affixed to a shaft which is pivotally supported in a holder mounted within the cabinet. To the shaft is affixed a handle for rotating the latch into engagement with and out of engagement with the shelf stop. When the handle is swung upwardly, it contacts a vertical handle position stop on the outer surface of the rear wall of the cabinet and the latch is pivotally moved by the shaft to the horizontal unlatched position. When the handle is swung downwardly, the latch contacts the shelf stop to secure the shelf in horizontal, latched position relative to the cabinet. The cabinet rear wall is configured to provide a handle access clearance space to facilitate pivotal movement of the handle for engaging and disengaging the latch.

  • Patent number: 4359251
    Abstract: A cabinet defining an interior space which may be optionally enclosed by a pivotally attached cover is disclosed. To the ends of the pivotally attached cover are connected brackets which include L-shaped slots. A shelf is provided which includes finger-tipped rods attached to its underside. The finger tipped rods are inserted within the L-shaped slots to allow the shelf to slide and pivot among three positions about the cabinet, namely, a first position vertically oriented above the cabinet, a second position horizontally oriented above the cabinet and a third position vertically oriented alongside the cabinet. The cover is supported when in an open position by a spring latch carried within the cabinet. The shelf is supported in its second horizontal position above the cabinet by hinged braces provided on the shelf underside, the brace being adapted to fit through slots in the cover and within holders arranged within the cabinet.
