Application March 28, 1955, Serial No. 497,212

4 Claims. (Cl. 312-345) This invention relates to drawers for articles of furniture and/or built-in closets, and more particularly to improvements in the cooperating guiding structure on the drawers and their guides.

An object of the invention is to provide a metal channel guide device for sliding drawers peculiarly adaptable for drawers molded from plastic material, although it will be obvious the same may function with metal drawers.

In this regard, novel features of the invention reside in the manner in which the drawer is'accurately guided into cooperation with the channel guide, the unique manner by which it is limited in its sliding movement relative to the channel guide, and the cooperative arrangement of structure on both the drawer and guide whereby the drawer is supported in suspension from the guide.

Other and further objects of my invention reside in the structures and arrangements hereinafter more fully described with reference to the accompanying drawings in which:

Fig. l is a partial perspective view of the front of an article of furniture showing a part of the novel guide channel construction in accordance with the principles of the invention.

Fig. 2 is a side elevational view of the novel guide shown in Fig. l and including the manner of sliding the drawer into the guide.

Fig. 3 is a side elevational view similar to Fig. 2 showing only the front portion of the guide, and with the drawer being guided thereinto by the guide member, while Fig. 4 shows the drawer supported in suspension from the guide.

Fig. 5 is a sectional view of the guide channel and a portion of the drawer taken along lines 5-5 of Fig. 4.

Fig. 6 is a partial side elevation of the guide channel and drawer with the drawer in its extended open position.

Fig. 7 is a sectional view of the guide channel as taken along lines 7-7 of Fig. 5.

Fig. 8 is a partial side view of a modified embodiment 7 of a guide channel with the drawer therein and with parts thereof broken away to provide a clearer understanding of the same.

Referring now to the drawings and in particular to Fig. 1, the novel drawer channel 16, constructed of metal, is shown secured in position on one side of a drawer opening 12 in an article of furniture 14. The channel It) is elongated to extend for the distance of movement of a drawer in the opening 12. Provided in the channel It) is a guideway (not numbered) defined by spaced upper and lower runners or flanges 16 and 18 respectively.

The upper runner 16 has a surface 20 (best seen in Fig. 5) which faces a surface 22 (best seen in Fig. 7) on the lower runner 18 to define the guideway therebetween. Interconnecting the upper and lower runners 16 and 18 is an edge wall or web 24having a plurality I 36 (see Fig. 3).

Fatented Feb. 3, 1959 ice of spaced detents or inwardly directed projections 26 which serve as guide bearing surfaces. The bearing surfaces 26 extend into the guideway and between the upper and lower runners, and although a plurality of bearing surfaces have been disclosed, at least one would suflice for reasons to be made clear.

At the forward end of the drawer channel 10 is a support 28. The support 28 is spaced from the runner 18 but has a support surface 30 which is horizontally aligned with the lower runner surface 22, and also an inwardly directed projection or bearing surface 32 which is aligned with the bearing surfaces 26. A reinforcing bend 34 resists bending forces applied on the support surface 30 when the same is in use. Provided on the channel 10 is a guide means 36 extending at a predetermined angle downwardly from the forward end of the lower runner 18 and below the guideway of the channel. Extending at a predetermined angle downwardly into the path of the guideway and from the forward end of the upper runner 16 is a limit means 38.

A drawer 40, shown in dot-dash lines in Figs. 2 and 3 and in full lines in Figs. 4, 5 and 6, is adapted to slide in the guideway of the drawer channel 10 and be supported in suspension therefrom. The drawer 40 includes side walls 42 having laterally projecting flanges 42a of substantial height. In the drawings it will be noted that only one sidewall flange 42a and its forward portion, and only a corresponding drawer channel 10 are shown for purposes of illustration although it will be obvious that there will be two such channels, one at each side of the opening 12. The side flanges 42a are adapted to slide in the guideway between the upper and lower runners 1S and 20 and to support the drawer 40 in suspension from the lower runner surface 22. In order to introduce the side flanges 42a of the drawer into the guideway of the drawer channel it the drawer is tilted upwardly at its front end at an angle as best seen in Fig. 2, whereby the side flanges 42a will pass between the horizontally staggered support 28 and the limit member 3%.

Continued movement of the side wall flanges into the guideway channels 16 and toward the rear thereof (see arrow 43 in Fig. 2), will bring the rearward portions of the side flanges 42a into abutment with the guide member The angle of the guide member 36 is so predetermined as to direct the side flanges 42a of the drawer 40 upwardly into the guideway (see arrow 44 Fig. 3), in response to continued movement of the drawer. Once the side flanges 42a are positioned between the upper and lower runners 16 and 18 their substantial heights provide bearing surfaces which ride against the inwardly projecting bearing surfaces 26 and 32 as the drawer 40 is slid back and forth in the drawer opening 12.

Referring now to Figs. 2 to 6 it will be noted that the side flanges 42a are provided with a depressed runner perticn 46 and a rearw rd raised portion 48 each of which, as a result of their substantial height, enables the side wall 42 to ride against .the bearing surfaces 26 and 312. The connecting portion 50 between the raised and depressed portions 48 and 46 provides a limit means on the side wall flange 42a, and is directed at the same angle as the limit means 38 on the channel It).

When the drawer 5-9 is moved back and forth in the channels M9 its movement is limited in the closing rection by a front piece 52 (Fig. 4), on the drawer abutting against the sides of the drawer opening 12;, while its opening movement is limited by the drawer limit means 543 abutting the channel limit means If it is desired to remove the drawer 449 from the opening 12 and from the side drawer channels it the drawer is moved in an opening direction until the limit means 50 abuts and cooperates with the member 3%. The drawer is then tilted to an angle greater than the angle of the limit means 38 so that the rearward portion 43 of the side wall flange 42a moves between the staggered guide member 36 and the limit member 33-with' the depressed runner 46 and subsequently'theraised runner 43 sliding on the support surface 36 until the drawer is removed.

Because of the impacts applied to the limit means 38 and the guide means 36 by'the drawer 4t} during its manipulations, rib means 54 are formed on each of them and between their respective runners to reinforce the same. Securing openings 56 and 57 are defined in the edge wall 24 of each of the drawer channels 19 to provide access for screws 53 (Figs. 2 and'7) or other securing means. openings 56 are elongated to permit adjustment of the channel 19 relative to the walls of the opening 12 to which they are to be secured; After the channel it) has been adjusted to its desired location a screw 58 may then be applied to the opening 57 to anchor the same from further adjustment.

In the embodiment shown in Fig. 8, the support surface 39 is provided at its entrance end with a stop lip 131. The lip 131 is bent upwardly int-o the guideway from the end of the surface 30 to provide a rest against which will seat the lower surface of the rear raised portion of the side wall 42, as best seen in Fig. 8. Hence, the stop lip 331 serves to restrain and hold the drawer to oppose accidental displacement or removal of the same from its closed position.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation maybe made by those skilled in the art, without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.

We claim:
