10 Claims, 5 Drawing Figures DRAWER SLIDE AND GUIDE ASSEMBLY This invention is an improvement on my prior U.S. Pat. No. 3 .3 65,26 1

BACKGROUND AND SUMMARY OF INVENTION Although quite sophisticated and complicated guide and slide means are provided for dresser drawers, it is desirable to have inexpensive and rugged assemblies available for low cost,

. for the slide-guide assembly, yet at the same time provide a positive stop against inadvertent pulling out of a dresser drawer.

DETAILED DESCRIPTION The invention is described in conjunction with the accompanying drawing, in which:

FIG. 1 is a fragmentary perspective view, partially in phantom, of a section of a dresser employing the inventive sliding assembly; I i

FIG. 2 is a perspective view of a dresser drawer'of the type seen in FIG. I, but from the rear so as to further illustrate the character of the slide assembly;

FIG. 3 is a fragmentary perspective view, partially in exploded form, showing the cooperating portions of the drawer S p a FIG. 4 is an enlarged transverse sectional view of the slide and guide assembly of the invention; and I FIG. 5 is a longitudinal sectional view on an enlarged scale of the parts seen in FIGS. and 4.

In the illustration given, and with particular reference to FIG. I the numeral designates a dresser drawer which is equipped with a front handle, as at II, and a slide element 12 adapted to move on a stationary guide 13 (compare FIG. 4). In FIG. 2, the same drawer is seen, but from the rear, wherein the slide I2 is seen to be equipped with an upturned portion 14 which can be seen in greater detail in my previously mentioned earlier'U.S. Pat. No. 3,365,261, and another related U.S. Pat. No. 3,328,107.

The guide member 13 is of generally T shape, while the slide member is generally channel shaped. In the metal channel 12, I provide a detent 15 which projects downwardly from the top wall of the channel. Thus, the detent 15 can be moved into selective engagement with a spring clip member 16 provided on the interior upstanding face of the guide 13. Most advantageously, aslot 17 is provided in the top surface of the guide 13 to accommodate the mounting of the spring clip 16.

The spring clip 16 is seen to have an intermediate raised portion 18 which coacts with the detent 15 in limiting withdrawal of the drawer 10 from its associated cabinet. However, it is possible to overcome the resilient resistance of the spring clip 16 so that the drawer can be completely withdrawn, as by having the detent 15 force the upwardly projecting portion 18 downwardly and pass thereover as seen in FIG. 5 when the guide 12 is moving to the left as indicated by the arrow.

It will be seen, particularly from a consideration of FIG. 5, that the spring clip member 1 6 is provided adjacent the forward end of the guide member 13, while the detent 15 is provided adjacent the rear end of the slide member 12. It will also be noted that the detent 15 is provided in the portion of the slide 12 which is bolstered by transverse ribs 19. Thus, the sides of the slide 12 are rigidified against spreading or other distortion which might limit the effectiveness of the detent 15 in engaging the spring clip 16. By this means, I am able to achieve a satisfactory stopthrough using a relatively minor upset portion on the bight 20.0f the slide member 12. It will be appreciated that the creation of a substantial sized detent in place of that pictured at 15 could materially weaken the slide 12 and interfere with its desired sliding action on the guide 13. In contrast to the foregoing, the spring clip 16 is of substan- 'tial length and size so as to provide an effective temporary stop when initially engaged by the detent 15. The size and shape of the spring clip 16 insures that the interfering action attendant on complete removal of the drawer does not unduly stress the spring clip 16. In particular, the spring clip 16 has a straight V portion, as at-l8a and l8b (see FIG. 5) which projects above the slot bottom wall about 0.1 inch. Thereafter the length of the clip 16 is made up of an S shaped portion as at 18c and 18d. This provides an advantageous combination of a straight stop and a curved bias spring, permitting the detent '15 to normally engage the clip defined by 18b and 18c, but, upon the application of greater force, to overcome the clip bias and permit the drawer to be removed. The upturned portion 18d prevents the clip from biting into the wood when stressed. Merely by locating (or relocating) the detent 15 at different positions, along the slide 12, the extent to which the drawer can be initially withdrawn can be changed.

From the foregoing, it will be seen that the drawer can be inserted. easily, yet is restricted against withdrawal. This is accomplished by the shape of the clip and the angle of contact, as well as the angle of the detent itself. Both the angle of contact on the clip 16 and the angle provided within the detent 15 are steeper in the direction of drawer extraction than the angle encountered when the drawer is being inserted. The clip is advantageously constructed of spring steel, but, in certain instances, may also equally advantageously be constructed of resilient plastic material. The provision of the steeper angle, as at 18b, than that encountered as at facilitates insertion while distinctly hindering to a greater extent drawer withdrawal, yet in a fashion that can be readily overcome if consciously desired on the part of a user.

It will be noted that there is a pronounced arch at 18c, and, in the operation, the detent 15 (at its lowest point) engages the arched portion 180, tending to deflect the spring clip 16. Optimally, the gauges of metalused in the spring clip 16 and the slide 12 are of the same order (about 0.025 inch). This results in a slight deformation or deflection of the detent 15 (as well as the spring clip 18), should the tolerances in the engaging parts be such as to otherwise make the withdrawal difficult.

In the preferred version of theinvention (see FIG. 5), the spring clip 16 is equipped with a countersunk portion 21 which serves a dual purpose. First, it permits a substantial portion of the clip to lie flush with the bottom 17a of the slot 17, thereby insuring good resilient action during attempted withdrawal. Secondly, the countersunk portion 21 insures that the head 22 of the wood screw 23 is suitably recessed so as to avoid any possible inadvertent engagement therewith by the detent 15. It will be seen that a realtively elongated woodscrew 23 is employed, and advantageously this length is such as to extend through the entire depth of the guide 13 into the parting rail (not shown) of the dresser. Thus, by a single screw installation, both the spring clip 16 is fixed to the guide 13, and the guide 13 is secured to the basic structure, i.e., the parting rail, of the dresser.
