Abstract

Abstract A drawer of molded plastic construction in combination with alternative support systems, as well as alternative design of the front panel of the drawer, provides storage versatility meeting a myriad of end uses. The drawer has one of two front panelled configurations; in the first case being adapted to receive a wood or other material facade carrying a drawer pull and in the other instance having an integrally molded handle or pull facility to lend itself for other end uses. The drawer may be manufactured in several sizes, but the unique design of the drawer makes each of the drawers compatible with other drawers of the same size to make them nestable or stackable. The unique configuration of the drawer permits use of the drawer in structures defining oversize drawer receiving openings or, in more economical structures, permits the use of the drawers in spaced relationship utilizing only side supports therefor. The single drawer configuration with exception of the front panel, permits the drawer to be mounted wholly on conventionally found side channelled or guides and at the same time permits alternative mounting of the drawer on a single track or rail super-positioned over the drawer by the means of a simple bracket member carrying a wheel to engage the track and which is receivable by the rear wall of the drawer. In the latter installation, the drawer is self-closing and selfaligning.
