23 Claims.

This invention relates to suspensions for drawers, and more particularly to the extensible type roller suspension wherein the drawer is supported when in a fully opened position.

This invention is particularly useful for but not limited to food preserving cabinets having a food retaining drawer movable into and out of the cabinet and having a cover or closure for the drawer disposed within the cabinet. The cover or closure in such a structure is disposed for sealing engagement with the drawer to prevent air from circulating therethrough.

An object of this invention is to provide an extensible drawer suspension whereby the drawer may be moved from a position in sealing engagement with a drawer cover out of and back into the cabinet without frictionally engaging the drawer cover during such movement.

Another object of the present invention is to provide a simple extensible drawer suspension having means thereon for upwardly moving the drawer into engagement with a cover or closure therefor when the drawerreaches its closed position, and for lowering the drawer out of engagement with the cover, whereby the drawer may be readily withdrawn from the cabinet.

A more specific object of the present invention is to construct an extensible drawer suspension in a manner to allow relative up and down or vertical movement between the parts thereof whereby the drawer may be raised into sealing engagement with a cover or closure therefor.

Other objects and advantages of the present invention will be apparent from the following description and the drawings, wherein:

Fig. 1 is a' perspective view showing a drawer in its fully opened position which is being supported by my.novel suspension;

Fig. 2 is an exploded perspective view showing the elements of my novel drawer suspension;

Fig. 3 is a vertical cross section taken' along line 3-3 in Fig. 5;

Fig. 4 is a partial cross section taken along line 4-4 in Fig. 5;

Fig. 5 is a. partial vertical cross section taken along line 5-5 in Fig. 3;

Fig. 6 is a cross section taken along line 6-6 in Fig. 1; and

Fig. 7 is a cross section taken along line I-l in Fig. 6.

Referring more specifically to the drawings, wherein like parts are designated by the same numeral throughout the figures, the novel suspension comprises a stationary cabinet track member I0, a movable drawer track member I2,

2 and an intermediate member I4 which is movable relative to both the stationary track I0 and the drawer track I2 (see Fig. 2).

The stationary cabinet track member ID comprises a U-shaped channel having an upstanding web portion I6, a flange I8 extending inwardly from its lower edge and providing an upwardly facing track surface, and a flange 2D extending inwardly from its upper edge and providing a downwardly facing track surface. The stationary track member I0 is adapted to be secured to theV side of the cabinet 22 by rivets or any other suitable means, not shown. Adjacent its rear end,y

the ange I8 of the track Ill is provided with an upstanding raised portion or bump 24 which is for the purpose more fully described hereinbelow (see Figs. 2, 5, and '7). An elongated slot 2E having an enlarged opening 28 at its rear end is provided in the upstanding portion I6 of the stationary track I.

The movable drawer track member I2 is preferably formed of a pair of

angle irons

30 and 32 which are adapted to be secured to the side of the drawer 34 by rivets 36 or any other suitable means. The angle irons are disposed with their

flanges

38 and 40 in back to back relationship to` form both upwardly and downwardly yfacing track surfaces. The mid portion of the flange 38 of the angle iron 30 is cut away as at 42 to interrupt the upwardly facing track surface to provide a clearance for the purpose more fully described below. Adjacent its front end, the flange 40 is provided with a depending bump 44 similar to the bump 24 on the flange I8 of the stationary track.

The intermediate member I4 comprises a U- shaped channel member having upstanding web portion 46 and upper and lower inwardly extending flanges 48 and 50 (see Figs. 2 and 3). A plurality of

rollers

52, 54, and 56 are mounted adjacent the lower edge of the upstanding portion 4B. As shown in Figs. 2 and 5, roller 52 is disposed adjacent the front end of the intermediate member I4; roller 54 is disposed substantially midway between the ends ofthe member I4; and roller 56 is spaced from the rear end ofthe member I4.

A pair of

upper rollers

58 and 60 are also mounted 48 and 50 are cut away to allow `the rollers to extend therethrough for engagement with up- .wardly and downwardly facing track surfaces of the track member I0.

When in assembled relationship as shown best in Figs. 1, 3, 5, and 6, the intermediate member I4 is disposed within the stationary cabinet track member I with the

lower rollers

52, 54, and 56 positioned to ride on the upwardly facing track surface of flange I8. The upper roller 88 is positioned for engagement with the downwardly facing track surface of ange 20 of the stationary track I to prevent the intermediate meinber from tilting downwardly when the parts are in the extended position shown in Figs. 1, 6 and '7.

The intermediate member is retained in this assembled relationship by a headed or shouldered rivet I4 which extends through the slot 26 in the stationary track and retains the intermediate member against both lateral and longitudinal displacement from the track Ill. The drawer track is disposed between the upper and lower rollers as shown in Figs. 3, 5, and '7. Preferably, the roller 54 is loosely mounted in the intermediate member for vertical relative movement thereto. Roller 54 may be conveniently mounted in this manner by providing it with a bore 6I having a larger diameter than stub shaft 63 by which the roller is supported. By this structure, the weight of the system presses the roller 54 against the flange I8 of the stationary cabinet track member IB and the upper roller 58 which rides on the upwardly facing track surface of the flange 38, presses the downwardly facing track surface of the drawer track I2 against the top of the roller 54 so that when the drawer 34 is pulled out of the cabinet 22, the drawer track .I2 frictionally engages the roller 54 and drives it along the stationary track I5, thereby causing the intermediate member to be positively driven at about half the speed the drawer is being moved.

The drawer is limited in its forward movement relative lto the intermediate member I4 by means of a stop pin 62 which extends from the drawer track member I2 and engages the gravity biased lever or catch 64 which is mounted adjacent the front end of the intermediate member I4. As shown in Fig. '7, the pin 62 and the lever 54 are located so that when the drawer is in its fully extended position, the outer end 66 of the lever is at about the mid portion of the drawer 34 so that the drawer may be held at about its center of gravity and the end of the lever 54 depressed by the thumb of the operator to release the catch and allow the drawer to be easily withdrawn or removed from the suspension mechanism.

Upon moving the drawer towards its closed position, the roller 54 acts to positively drive the intermediate member inwardly as was described above in the same manner as it acted to drive the intermediate member outwardly. When the drawer reaches its innermost closed position, the

roller 56 rides up on the raised portion or bump 24 and the bump 44 on the drawer track I2 rides up on the roller 52. The roller 56 is raised above its normal operating level by the bump 24, and it in turn raises the drawer track member I2 and the drawer secured thereto. The roller 56 through its connection with the intermediate member also raises the rear end of intermediate member I4 above its normal operating level and relative to the stationary cabinet track member Ill. In order to allow this vertical relaset portion 68 to interrupt the downwardly facing track surface to provide clearance for the roller 60. The roller 58 is lifted about half as much as rollers 56 and 6U. It is of smaller diameter than the roller 6D to provide a clearance above it and under the downwardly facing track surfaceA of the flange rvequal to the differences in the diameter of the rollers 58 and 5D. The engagement of the bump 44 on flange 40 of the `drawer track I2 with the roller 52 raises the 'front end of the drawer track and the drawer 34 so that the drawer is supported in a substantially tive movement to take place, clearances must be v level position. In this raised position, the drawer is in sealing engagement with a cover or closure li) which is supported in the cabinet 22 by any suitable means not shown. The upward movement of the drawer track member I2 relative to the intermediate member I4 which is caused by the engagement of the bump 44 with the roller 52 makes it necessary to provide a clearance between the upper roller 58 and the upwardly facing track surface of the flange 3S of the drawer track to allow this vertical movement. In the preferred embodiment described herein, the above described cutout or recessed portion 42 in the flange 33 of the drawer track I2 interrupts the upwardly facing track surface for this purpose. As shown in Fig. 5, the cutout portion is located so that when the drawer track is raised cr moved vertically relative to the intermediate member and the roller 58 carried thereby the roller 58 will extend into the cutout portion 42.

From the above described structure, it is readily seen that when the drawer is moved outwardly from its closed position shown in Fig. 5, the roller 56 will ride olf of the bump 24 and the bump 44 will ride off of the roller 52, thus lowering the drawer out of frietional engagement with the cover 'I5 and allowing it to be easily moved both outwardly and inwardly.

While the preferred embodiment of this invention has been shown and described herein, it is obvious that many modifications may be made in the disclosed structure without departing from the spirit and scope of the appended claims.
