June 7, 1966 A. c. BURR FOLDING DISPLAY TABLE 2 Sheets-Sheet 2 Filed March 26, 1964 INVENTOR. fllan C. Barr fiTTaRNi'K United States Patent 3,254,614 FOLDING DISPLAY TABLE Alan Carleton Burr, East Norwalk, Conn., assignor to Howe Folding Furniture Inc, New York, N.Y., a corporation of Connecticut Filed Mar. 26, 1964. Ser- No. 354,866 12 Claims. (Cl. 108122) This invention relates to a multiple position display table. It is often desirable for advertising or for instruction, for example, to display a number of articles or a number of parts of an article so that they can be conveniently seen by a number of people simultaneously.

An object of this invention is to provide a display device on which one or many articles or parts of an article may be readily mounted and demounted, and which canbe adjusted to make the articles or parts of' an article visible to a number of people who may be seated at different distances away, or at different elevations, as in an amphitheater, lecture hall and the like. Another object of the invention is to supply such a device which can be readily converted from operative position into folded inoperative position in which it occupies a minimum of space and can be moved or stored standing up.

The invention will be best understood when the following description is read in connection with the drawings, in which,

FIGURE 1 is a top plan view partly cut away.

FIGURE 2 is a side elevation.

FIGURE 3 is an end view'taken on the line 33 of FIGURE 1.

FIGURE 4 is a detail view taken on the line 4'4 of FIGURE 2.

FIGURE 5 is a side elevation showing the table top in inclined position.

FIGURE 6 is a view similar to FIGURE 5 but showing the structure with the top inclined at a greater angle, and

FIGURE 7 is a side elevation showing the structure in fully folded position.

The embodiment of the invention shown in the drawings comprises, a top 10 which preferably is a pegboard perforate i.e., to facilitate attachment thereon of articles to be displayed. Angle brackets 10a and 10b project downwardly from the under surface of the top 10 in parallel relation adjacent the lateral edges of the top.

Legs 12a and 12b are interconnected at the top by cross member 13 which is rotatably mounted between angle brackets 10a and 10b on hearing pins 13a and 13b. Legs 14a and 14b are interconnected at the top by cross member 16 which is pivotally connected at its ends between the link-leg members 20a and 20b respectively, on hearing pins 16a, 16b, FIGS. 5 and 6.

At the end of members 20a and 2011, which are their upper ends when the structure is folded, are hinge leaves 24a and 24b which project upwardly and inwardly to- Ward the under surface of the top, and are pivotally engaged by pivots 26a and 26b respectively, with the hinge leaves 28a and 28b which project down from the under surface of the table, preferably from the angle members 10a and 10b respectively, toward the hinge leaves 24a and 24b respectively. I When the structure is fully folded, members 14a, 20a and members 14b and 20b will be substantially aligned and disposed in a plane which is only slightly angularly related to the plane of top 10, and legs 12a and 12b will be in a plane parallel to, and directly adjacent to, the plane of top 10. In this folded position, as seen in FIG. 7, a mobile, self supporting display board is provided.

The link members 20a and 20b are 'shown as angle members and the pivot points 16a and 16b are disposed intermediate the ends of link members 20a and 20b respectively, and when the table isfolded as shown in FIGURE'7 the legs 14a and 14b will be substantially aligned with, and received in, the portions of members 20a and 26b which extend below the pivots 16a and 16b.

The feet of legs 12a, 12b and 14a, 14b are turned outwardly at their lower extremities and preferably are sup ported on casters 0. As best seenin FIGURE 7 the legs 14 will be spaced from the legs 12a, 12b respectively at their lower ends only sufficiently to allow the structure to stand on its own feet in folded position. To prevent the pairs of legs from moving too close together a cross member 40 is provided between the leg-links 20a, 20b adjacent their lower ends in position to act as a stop limiting the folding movement of brace-links 34a and 34b which will be described.

When the structure is fully unfolded as seen in FIG. 2 the leg-link members 20 will be disposed directly under the top 10 and in a plane which is parallel, and directly adjacent to the top 10, with the legs 14a, 14b extending downwardly in open position, and disposed slightly outwardly at an angle, relative to the link members 20a and 20b respectively.

When the table is partly unfolded, as it usually will .be in use, in order to dispose the top 10 at an angle where objects displayed upon it may be seen by a number of people, even if they are seated in rows arranged one behind the other, the leg-links 20a and 20b will be angularly disposed both relative to the top 10 and to the legs 14a and 14b respectively as seen in'FIGS. 5 and 6. In order to hold the top in an inclined position the lower edge of the angle members 10a and 10b are notched with a series of notches n adapted to receive the free ends of

arms

30a and 30b respectively, which at their lower ends are pivoted to the links 20a and 20b respectively by pivot means 32a and 32b. By moving

arms

30a and 30b and inserting their free ends selectively in similarly disposed notches n in angle members 10a and 10b respectively, the inclination of the top can be varied through the whole range from horizontal to vertical positions. Stops 33a and 33b are provided on members 20a and 20b to limit movement of

arms

30a, 30b downwardly.

A cross bar 15 is mounted for rotation between legs 12a and 12b intermediate their end-s on pivot bearings 15a and 15b, and brace-link means 34a and 34b extend from the cross bar 15 to a cross bar 35 which is mounted for rotation between the leg-links 20a and 20b, adjacent their upper ends, on pivot bearings 35a and 35b. Similar brace-link means 36a, :36b extend from cross bar 23 which is mounted for rotation between leg means 14a and 14b on pivot pins 23a and 23b, to cross bar 37 which is mounted for rotation between members 19a, 10b on pivot pins 370 and 37 b, which are disposed between hinge leaves 28a, 28b respectively and the cross bar 13, longi- .tudinally of the top.

As a supplement to a perforate top 10 a non-perforate cover member 38 is provided which is adapted to fit snugly over top 10 so that if desired the structure may be used as an ordinary table. Also there may be objects which can be attached for display to a nonperforate top.

There has thus been provided a structure in which the objects stated above are attained in a simple and thoroughly practical manner.
