INVEN'I'OR. MARTIN O. RILEY AT TORNE Y MOLDED DRAWER BACKGROUND OF THE INVENTION The invention relates to drawers for cabinets, and more particularly to one-piece drawers adapted for use in recreational vehicles such as boats, trailers and campers wherein travel motion often causes migration of the drawers within cabinets.

One of the problems of drawers is the tendency of the drawer to move along its guide rails from closed position to an open position from which articles within the drawer can be lost. Also, cleaning of drawers made in generally rectangular configuration is often difficult because of the sharp inner corners. Centrally guided drawers have achieved wide acceptance but are normally expensive to build. The present invention overcomes these objections in a molded or vacuumformed plastic drawer in which corners are rounded.

SUMMARY OF THE INVENTION The invention contemplates a drawer for a cabinet having central guide members which comprises a drawer bottom with spaced guide fins on the bottom and spaced lock lugs on the bottom. A drawer wall rises upwardly and slightly outwardly from each of the back and side edges of the bottom. A front wall rises upwardly from the front bottom edge. An outwardly extending stiffening rim surrounds each of the back and two sidewalls at the top of the drawer. Spaced guide members protrude from the back rim upwardly. A stacking lug on each wall adjacent a wall comer precludes surface-to-surface contact between adjacent drawers when stacked one within the other.

The objectives of the invention are to provide a drawer which is easily cleaned by having no scams or joints and which has rounded internal corners and which locks in place in closed or open positions. The invention has a further objective of providing a drawer which can be inexpensively molded or vacuum formed, which is rigid for its weight and which affords a flat panel to which decorative handles and facia boards may be attached.

These and other advantages of the invention are apparent from the following detailed description and drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a longitudinal sectional elevation of a drawer in accordance with the invention in place in a cabinet frame;

FIG. 2 is a rear elevation of the drawer of FIG. 1 in place;

FIG. 3 is a bottom plan view of the drawer of FIG. 1; and

FIG. 4 is a fragmentary top plan view of the back rim portion.

In FIG. 1 a drawer in accordance with the invention is supported within a fragmentarily shown cabinet 11 on a longitudirial central rail 14 and guided by the lower central rail 14 and an upper central rail 15. The cabinet may have a top 16 supported .upon

transverse framing members

17 and 18 between which guide rail extends. Lower support and guide rail 14 extends between lower framing members 19, 21. Guide rail 14 is the lower guard rail for drawer 10 but is the upper guide rail for a lower adjacent drawer (-not shown).

Drawer 10 is preferably molded or vacuum-formed in an integral shape. The drawer has a substantially rectangular bottom wall with rounded corners, spaced

sidewalls

26, 27 and backand

front walls

28, 29, respectively. Backwall 28 and the sidewalls diverge outwardly as they rise from the bottom wall. Front wall 29 is substantially perpendicular to the bottom wall. Each of the backand sidewalls terminates at its upward edge in an outwardly projecting flange or stiffening rim. The

sidewalls

26, 27 have curled

rims

31, 32, respectively, and backwall 28 has a curled rim 33. Rim 33 has two

central guide bosses

35, 36, best seen in FIG. 4. Each boss has a guide surface 37. The surfaces are spaced apart a distance substantially equal to the transverse width of upper guide 15. As can be seen in FIG. 2, each boss slopes downwardly and outwardly in a ramp 38.

Also visible in FIG. 2 are spaced

guide fins

41, 42 which center a drawer with respect to lower guide rail 14. In FIG. 3 the

fins

41, 42 are seen to flare outwardly at their rearward ends adjacent the rear of the bottom wall to a distance greater than the transverse width of the guide rail. The flared portions 43, 44 of the fins guide the drawer onto the bottom guide rail after the upper guide bosses have been engaged with the upper guide rail. The forward face 45 of each fin acts as a stop to retain the drawer when it is nearly fully opened, butting against lower framing member 19.

As previously mentioned, one problem with sliding drawers is their tendency in moving vehicles to jar from their closed position. In order to counteract this opening motion the drawer of the invention has

lock lugs

51, 52 depending from the drawer bottom wall near the juncture of the bottom wall with the front wall. Each lock lug is triangular with an engaging face 53 adapted to seat against the inner surface of framing member 19 or its like element within a cabinet. The bottom face 54 of each lock lug tapers to a juncture with the bottom wall such that the drawer may be pushed closed with little effort since the drawer would ride on the sloping lug bottom surface up over framing member 19 and drop into locked position, as shown in FIG. 1.

In order to introduce the drawer into. the cabinet, which is conventional in construction, the front of the drawer is lifted. slightly to depress the rear guide bosses sufficiently to enter the drawer opening and engage with guide rail 15. At the same time the rearward edges of

rims

31, 32 are placed into the drawer opening. The rear of the drawer is then lifted sufficiently for

guide flns

41, 42 to pass bottom framing member 19 and engage about bottom guide rail 14. The drawer is then continually pushed toward a rearward position until the lock lugs 51, 52 encounter frame member 19. An additional inward thrust surmounts member 19 and the drawer falls into locked position, lugs behind member 19.

It is presently contemplated that the drawers in accordance with the invention be injection molded from high-impact polystyrene. Other materials of the strength and finish characteristics of polystyrene may be used. The material depends in part on the drawer size, as well as'upon the method of fabrication. Molded polystyrene is well suited to drawers presently used in the industry, which are principally 5 inches deep, 17% inches long and from 10% inches to 20 inches wide.

While decorative panels may be affixed directly to front wall 29 of the drawer, it is preferable from the standpoint of appearance for a facia board 61 to be pinned or otherwise attached to the front face. Facia board 61 may match the rest of the material of the cabinet and have affixed thereto a handle 62. The treatment of the exterior of the front wall is capable of great variation and does not form a part of this invention aside from the ability of the front wall to accept the wide variety of trim members as desired.

The upward-downward divergence of the sidewalls and backwall of the drawer makes it possible to stack one drawer within another. However, the surface-to-surface engagement of all of the drawer surfaces would tend to lock the stacked drawers one to another. The drawer of the invention therefore has upper stacking lugs, such as the lugs 65, depending from the rim adjacent each corner of the drawer. After adjacent drawers have been placed one within the other to a certain depth the stacking lugs contact the drawer surfaces and prevent surface-to-surface contact which would inhibit withdrawal of the drawer from its neighbor.

By utilizing the unitary drawer economies can be anticipated in fabrication, storage and shipment. The drawer is substantially seamless and is therefore easily cleaned. Many of the plastics from which the drawer can be made are washable in warm or hot watersuch that the drawer lends itself to sanitation. The rim itself may vary depending on the strength of the material used. A flat rim or a tubular rim may be utilized if such strength is necessary.
