3 Claims.

This invention relates to desks and in its more specific aspects is directed to a drawer guide for a desk which will compensate for the warping that takes place in drawers to enable them to freely slide in and out of the desk.

The object of this invention is to provide a desk drawer guide which is pivotally mounted in the well of the desk to enable the drawer to be freely moved in the guide and in which the guide parts can move at right angles to the longitudinal movement of the drawer to thereby overcome the binding efiect of a warped drawer in the guide.

In the drawings Figure 1 is a sectional elevational view of a desk incorporating the drawer guide;

Figure 2 is a sectional view taken along the line 2-2 of Figure 1; and

Figure 3 is a partial perspective view of the drawer guide.

Referring now to the drawings, numeral I designates the body of a desk having a drawer 2 therein which is movable in and out of the desk well. A guide 3 is mounted in the desk to facilitate drawer movement.

The guide is composed of two channel members constituting rails 4, 4, each of which is pivoted to the desk by means of a pin 5, only one of which is shown, pins 5 being suitably secured to one of the structural members of the desk. The other member of the drawer guide is an equalizer bar 6 which is disposed between the track members at their unpivoted ends. Equalizer bar 6 is supported on the rear wall of desk I in a suitable bracket I provided with a pin 8 extending through and about which the equalizer bar 6 pivots. Equalizer bar 6 is provided with tangs 9, 9 which extend through slots formed in the ends of rails 4, 4, the shoulders on the bar preventing inward motion of the rails toward each other and the side walls of the well in which the drawer is received limiting the outward movement of rails 4, 4, said equalizer also maintaining the proper spacing of said rails.

The drawer 2 is equipped with a bracket I0 provided with rollers II (one not shown) which are preferably anti-friction bearings that travel in rails 4, 4. The lower portion of the drawer is supported on rollers I2 (only one of which is shown) each of which is rotatably supported in a bracket I3 suitably secured to the side walls of the desk well. The bottom edge of the side walls of the drawer rests upon the rollers II and this lower edge may be suitably reenforced to prevent wear. When drawer 2 is being withdrawn from the desk well, it pivots about rollers I2, causing roller I to bear against the upper edge of rails 4, 4. A stop in the form of pins l4 (only one of which is shown) secured in each of the rails 4, 4 is engaged by rollers I I to prevent accidental withdrawal of the desk drawer although the drawer may be removed from the desk in a manner well known in the art.

When desk drawers are operated in guides that are rigidly secured to the walls of the desk, they will frequently stick when sliding them along the guide because of drawer distortion or warping. In view of the tendency of presently available woods to excessively warp, the binding and sticking of the drawer in rails 4, t becomes increasingly greater when the rails are rigidly mounted in the desk well. This sticking and binding in the rails 4, 4 is prevented by having them pivoted on pins 5 with equalizer bar 6 loosely associated with the unpivoted ends of the rails to permit vertical motion of the rails relative to the well of the desk and to each other. When the drawer is moved along rails 4, 4, they adjust themselves to the particular drawer shape, thereby equalizing the pressure on each rail and preventing said sticking and binding to enable a free and easy movement of the drawer along the rails.

Having fully described my invention, that which I claim as novel and desire to protect by Letters Patent of the United States is:

1. In a desk, a drawer guide comprising a pair of longitudinally extended rails and an equalizer bar disposed between said rails at one end of said pair of rails; means to pivot the other end of said pair of rails to the desk; and means to pivot said equalizer bar to the desk, said equalizer and rails adapted to pivot relative to each other when a desk drawer is moved along said guide.

2. A desk drawer guide comprising two side rails; means to pivot one end of each of said rails to the desk; an equalizer bar disposed between the unpivoted ends of said rails; means to pivot said equalizer to the desk; and a drawer longitudinally movable along said rails, said drawer pivoting said rails and equalizer about their respective pivoting means as it moves along said rails to equalize the drawer pressure on said rails to thereby facilitate movement of said drawer in the guide.

3. In a desk, a drawer guide comprising a pair of rails, means pivoting each rail at one end thereof to the desk, an equalizer bar connected between the other ends of said rails, means pivotally supporting said equalizer bar on said desk at a point between said rails, the connection between said rails and said equalizer bar permitting 3 4 relative motion between these parts; and a drawer longitudinally movable along said guide, said UNITED STATES PATENTS rails and said bar pivoting relative to each other Number Name Date as said drawer moves along said guide. 697,471 Gelcke 15, 1902 CLARENCE C 5 1,985,550 Raggio Dec. 25, 1934 2,179,138 Stickley NOV. 7, 1939 REFERENCES CITED 2,223,071 Koch NOV. 26, 1940 The following references are of record in the file of this patent;
