Abstract
Abstract A cabinet assembly which is particularly useful in storing small hardware items such as nuts, bolts, screws, and washers, includes a plurality of drawers and a unitary molded plastic cabinet. The unitary molded plastic cabinet has an open back, a front formed of a grid of horizontal and vertical cross bar defining openings for the drawers, slides extending rearwardly from the grid for receiving and supporting the drawers, and a flange in each of the openings which extends downward from a horizontal cross bar and acts as a stop for both inward and outward travel of the drawer.

Claim 1
Independent Claim
296 words
A cabinet assembly comprising: a plurality of drawers each having a front, a back, first and second sides, a bottom, and an at least partially open top; and a unitary molded plastic cabinet for receiving the plurality of drawers, said cabinet being molded from a minimum of plastic material and easily removable from the mold, said cabinet comprising: a top surface; a bottom surface; first and second side surfaces; an open back with no projections normal to the top, bottom, or first and second side surfaces; a front comprising a grid of vertical and horizontal cross bars defining openings for rows and columns of the drawers; slides on each side of each defined opening extending rearwardly from the grid for receiving and supporting the drawers rearwardly from the grid by a distance of between about one half and about two thirds of the distance from the front to the open back; and a flange in each of the defined openings extending downward from a horizontal cross bar, the flange being positioned with its front surface slightly behind the plane of the front grid to act against an inner top surface of the front of the drawer to limit inward travel of the drawer to a position in which the front of the drawer is substantially flush with the front grid, and the back surface of the flange acting against an inner top surface of the back of the drawer to limit outward travel of the drawer, the back surface of the flange being substantially coplanar with the back surface of the front grid, and wherein the cabinet has no substantial projection from the top, bottom and first and second side surfaces parallel to the front grid and rearward of the back surface of the front grid.
