RETRACTABLE TABLE TOP SHELF Filed June 18, 1965 1 George Consln INVENTOR.

United States Patent 3,185,114 RETRACTAIBLE TABLE Ti}? SHELF George .I. Cousin, 297 E. Lake Forest St.,

Knoxville, Tenn. Filed June 18, 1963, Ser. No. 288,834 3 Claims. (Ell. l0865) The present invention relates to an extensible and retractable shelf which, while capable of being used on any table Where a slide-away shelf would be practical and useful, is primarily designed and adapted for use on and in conjunction with customer serving and eating tables such as are provided in restaurants, hotels, cafes and similar food serving establishments.

One adaptation of the invention is directed to a slidingly mounted shelf which is slidingly bracketed to an underneath side of a restaurant or an equivalent table and which, when it is not in use, is retracted to assume a bidden or concealed position beneath and within the perimeter limits of the table top but is available and is so mounted at at least one accessible end of the table that it may be withdrawn and caused to assume an outstanding position where it then provides an extra facility which is capable of being used in a number of ways. For instance, where the service involved is that which is afiorded in a cafeteria it will be evident that the extending shelf may be employed to support one or more empty trays which are to be returned to the kitchen for washing.

In addition the shelf could be used, probably with a supporting leg, as a tray stand, that is, the tray with the meal thereon could be temporarily set on the shelf or stand until the articles of food have been transferred to the table in a now customary manner. Further, the traystand or shelf lends itself to acceptable use under crowded conditions as a place for an extra occupant where, for example, the ordinary table-end would not afiord a space sufiicient for such purposes.

Stated somewhat more explicitly the invention pertains to a leg-supported or equivalent restaurant or similar table which is, in accordance with the present invention, provided at one marginal edge or end portion with an extensible and retractible rack-type shelf, means being provided on the underneath side of the table top to slidingly mount the shelf and so that it lends itself to various trayserving uses. To the ends desired adapter brackets are fastened to the underneath side of the table top in spaced parallel shelf mounting relationship. The brackets are provided with tracks and the shelf has aluminum side members or rails which are slidingly mounted in the tracks.

In carrying out a preferred embodiment of the invention the shelf is of openwork rack-like rectangular form and is preferably provided at the outer projectible end thereof with a prop-like leg, said leg being capable of being folded and swung to an out-of-the-way position when it is not being used.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a top plan view showing a restaurant table in a conventional serving booth with the invention attached and appearing partly in elevation and partly in phantom lines;

3,185,114 Patented May 25, 1965 FIGURE 2 is a view taken on an enlarged scale and with parts in elevation, section and phantom lines, the section being taken on the plane of the section line 2-2 of FIGURE 1; I

FIGURE 3 is an end elevational view on a slightly enlarged scale, that is compared to FIG. 1, and observing the structure illustrated therein in a direction from right to left;

FIGURE 4 is an exaggerated detail view in section and elevation taken on the section line 4-4 of FIG. 1; and 7 FIGURE 5 is a View in perspective of an optionally usable table top, that is, a table top which is applicable to the aforementioned stand and thus employable as an auxiliary extra-person seating table structure in a manner to be hereinafter and again referred to.

Referring now to the illustrative, but not restrictive, views of the drawing it will be noted (FIG. 1) that the table is denoted, as an entity, by the numeral 6 and comprises a suitably supported and fixed table top whose top surface is denoted at 8 and the underneath or bottom surface of which is denoted at 10. To enable the reader to more fully appreciate the nature of the concept and principal improved result which is achieved the table is shown mounted between upholstered or equivalent seats or benches 12 facing each other with a table therebetween in a manner customarily employed in a customers booth such as is commonly employed in present day restaurants, lunch rooms and the like. The facility which is provided here is such in construction and purpose that it may be appropriately construed as either a shelf or a rack and, more explicitly construed, as a tray (self-service type) as indicated in phantom lines in FIG. 2.

In carrying out the preferred embodiment of the invention the shelf is extensible and retractable and is extended to the phantom line position illustrated in FIGS. 1 and 2 when in use and is retracted to assume the out-of-the-way full line position also there illustrated. While the shelf could be in the form of a panel it is preferably of openwork construction and is consequently more in the nature of a rack, the same being denoted generally by the numeral 14. It is of U-shaped construction and formed from a length of aluminum tubing bent upon itself between its ends to provide a bight portion 16 and a pair of coplanar spaced parallel legs or limbs 18. These limbs are provided on free ends thereof with caps 20 which constitute limit stops. The legs are slidingly mounted in the hollow or channel portions of the channel-like tracks 22, the latter being integral portions of an adapter bracket 24. The adapter bracket comprises an attaching flange 26 which is milled as at 28 and is firmly clamped againstthe underneath surface 10 of the table top and held removably in position by several (more or less) attaching screws 30. The track 22 preferably comprises an open-ended aluminum tube 32 which is split on one side as at 34.

With this construction the coacting legs of the U-frame 14 and are anchored and slidable back and forth in an obvious manner. The tubular cross members 34 are in spaced parallelism and located between the legs and thus make up a suitable rack. When this rack or shelf is pushed underneath the table, it is, of course, hidden or out of the way but is such that the bight portion 16 is available to permit withdrawal and extension to the. usable position.

illustrated. The end caps 20 on the legs 18 serve as stops and abut the inward ends of the tracks in the manner illustrated in FIG. 2. For stability a leg or prop is provided the same being denoted generally by the numeral 38. This a leg is generally T-shaped and the leg proper is denoted at 40 and is provided at arr-upper end with a sleeve-like collar 42 which is rotatable but frictionally mounted on the median portion of the bight portion whereby to permit the leg to be folded and retained in the out-of-the-way position shown in FIG. 2 when not in use orto be swung down and to assume a perpendicular position when in use. For balance the lower end of the legisprovided with a U- shaped crosshead which is denoted at 44 and which has downturned end portions 46 defining short legs which terminate in cap-like feet 48.

Manifestly, it would be Within the purview of the instant inventive concept to provide tables other than lunchroom and restaurant tables with the slidably mount ed hide-away tray stand. On the other hand,.it is be- .lieved that it is best suited to serve the main purposes herein shown and described. It is submitted that a careful consideration of the specification in conjunction with the views of the drawing will enable the reader to obtain a clear and comprehensive understandingof the invention. Therefore, a more extended description is regarded as unnecessary.

With reference now to FIG. 5 it will be seen that the numeral 50 designates an optionally usable table top. This top may be of the general rectangular construction shown, the same being provided on its underneath side 52 with a plurality of spaced appropriately arranged spring clips 54. These are simple double jaw clips which are so constructed that they may be releasably engaged with the rod members 35 or, if preferred, with the side frame members 34 whereby to provide a temporary extra serving table. In other words, instead of using the rack to support a self-serving tray (not de-;

tailed) the surface canbe employed to support the readily applicable and removable table top or leaf 50 and when the latter is not being used it can be kept in storage and in readiness for use.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
