Abstract
Abstract A drawer which is to be readily mounted to the undersurface of a shelf, cabinet or table, which is to be movable between a closed position and an open position. With the drawer in the open position, it assumes an inclined position to facilitate access into the internal compartment of a drawer. Secured to the exterior surface of each side wall of the drawer is a protruding member. Each protruding member is to fall within a recess, when in the open position, which is formed within a side rail assembly which mounts the drawer to the undersurface of the shelf, cabinet or table. With the drawer in the closed position, a separate locking means is engaged which prevents unauthorized movement of the drawer from the closed position to the open position.

Claim 1
Independent Claim
286 words
A drawer apparatus comprising: a side rail assembly comprised of a pair of substantially parallel spaced-apart side rails, each said side rail having an inner surface, said inner surfaces facing each other, each said side rail having a cam surface, each said cam surface including a recess, each said side rail terminating at a front edge; a drawer having an internal compartment enclosed by a front wall and a back wall interconnected by a pair of spaced-apart side walls, each said side wall having an exterior surface, each said exterior surface having a guide rail, each said guide rail extending from said front wall to a surface located directly adjacent said back wall but spaced therefrom, a said guide rail to slidably connect with a said cam surface to permit movement of said drawer relative to said side rail assembly, said movement of said drawer being between a closed position and an open position, said closed position not permitting access into said internal compartment, said open position permitting access into said internal compartment; and a protruding member mounted on each said exterior surface with there being two in number of said protruding members, each said protruding member being located between its respective said surface and said back wall, each said protruding member to engage with a said recess when said drawer is in said open position, said protruding members and said recesses preventing disengagement of said drawer from said side rail assembly when in said open position, upon said drawer reaching said open position the entire said drawer pivots to an inclined position (relative to said closed position) with each said surface of each said guide rail abutting said front edge of a said side rail.
