This invention relates to tables, and particularly to a table of the foldable type adapted to be collapsed into a relatively flat form for storage purposes. Specifically, the invention pertains to a table structure which is adapted to be folded 0 into a wall recess.

Relatively long narrow tables are used extensively 1n the cafeterias of schools and in rooms groups of people. In some instances, it is deone member forming a flush continuation of the wall surface. Such a table construction and arrangement serves the purpose for which it is designed, that is, to provide a convenient means by which tables can be removed from a floor to the floor. That is to say, since the table is con- Walls. In addition, such tables are devoid of legs at their ends which are connected to the walls so that even if the tables were demountable from the walls their disconnected ends would be unsupported by legs and would fall against the floor.

Stated another way, such prior foldable tables are complete only when attached to a wall, and

it is impossible to utilize them apart from the wall.

It isan object of the present invention to obviate the deficiencies of prior foldable tables dis- Another object is to provide a foldable table having a pair of top sections hinged together the ends and adjacent the hinge connection between the two table sections. A related object is to provide means for maintaining all three longitudinally-spaced pairs of legs vertical in all positions of the foldable sections, that is, when dicular to the floor.

Another object is to provide a foldable table structure in which the end legs are hinged at of the recess for guiding both sections vertically into place in the wall recess. As a particular feature of improvement, the attaching means are releasable to adapt them to be withdrawn from permit use of the table at locations remote from pivotally connected by attaching means are in the form of laterally slidable bolts adapted, when slid outwardly, to slidably engage in the guides and adapted, when slid inwardly, to be withdrawn from the guides to unlock the table and permit separation thereof from the wall.

Another object is to provide locking means on the outer table section engageable-with the sides of the wall recess for retaining the folded table structure within the recess, this means comprising a key-operated locking bolt.

Further objects of the invention will appear from the following description and from the drawings, which are intended for the purpose-of illustration only, and in which:

I Referring to the drawings in detail, the present improved folding table I is adapted for use either in connection with a wall I l of a cafeteria, auditorium, or other building, as shown in Figs. 1,2, and 3, or by itself, that is, apart from the wall as illustrated in Fig. 3. The foldable table will first be described per se, and. the means adapting it for installation in a wall recess will thereafter bediscussed.

The table H), which forms the subject matter of my application, Serial No. 306,527, filed August 271, 1952,. for Folding Table and Cabinet Construction, said application being a continuationin-part of the present application. Said table includes a pair of top sections 15 and I6 which are preferably, although not necessarily, made from plywood and have a plastic or other hard, heat-resistant and mar-proof surface. Each of the table top sections is shown to be longer than the height of the table. The table sections are reinforced and made more rigid. by means of longitudinally and transversely extending strips and cleats l1 and [8. Referring to Figs. 4 and 5, the inner ends of the top sections 15 and [6 have angular hinge brackets Ziland 2| secured thereto by suitable means, the hinge brackets having downwardly projecting portions 2| which are a hinge pin or rod 22 extending transversely of the table, it being noted that the hinge pin is disposed below the plane of the table top. By this hinge connection, the top sections l and I6 areadapted to be folded taken on line 5-6 a are spaced from into a substantially parallel, side-by-side relation and to be unfolded to the fully open or coplanar relation shown in Fig. 2 margins in alignment.

Secured against the under side of the top section at a distance from the free end thereof slightly shorter than the desired height of the table is a'pair of hinge brackets to' which is pivoted a first leg means 26. The leg means includes vertical legs 21 connected by a cross-bar 28, the upper ends of the legs being pivoted to the brackets. A second leg means 30, comprising legs 21 and a cross-bar 28, is similarly pivoted to hinge brackets 3! carried by the other top section US. As shown in the drawings, hinge 25 and3l are desirably so disposed that the pivotal axes of the respective leg means 28 and 30 the free ends of the respective distance slightly less than the length of the leg means. Accordingly, the leg means always rest upon the floor in all positions of the table. A third leg means 33 is disposed at the center of the table and includes a pair of legs 34 which are connected by a cross-bar 35, the upper ends of the legs being pivotally connected to the hinge pin or rod 22.

Positioning means are provided for maintaining the leg means 25, 30, and 33 in vertical position, regardless of the relative positions of the table top sections 15 and 16. This means includes a pair of slide elements 31 which. are slidably mounted on the central legs 34. Pivotally connected between pins 38 on the slideelements 31 and transverse pins 39 on' the hinge brackets 20 and 2! are link elements 40. It will be noted that the link elements 40 are pivotally attached to the respective hinge brackets at joints spaced from. the axis 22 of pivotal connection, between the top sections. By this means, the leg means 33 is maintained vertical, that is, it is caused to assume a position in which it bisects the included angle between the sections and to lie parallel 'to the sections when the latter are completely folded together. Connecting links 42 and 43 are pivotally connected between the cross-bar 35 and the respective cross-bars 28 of the leg means 26 and 30, the cross-bars 28 carrying arms 44 and pivot studs 45 for this purpose (Fig. '1). The links 42 and 43 define, with the sections l5, l6, and legs 21, 34, parallelograms which maintain the legs 21 parallel to the legs 34, that is, in a vertical position. The legs 21., 34 and connecting links 42, 43 are preferably made tubular, and these components, in addition to. the hardware therefor, are preferably chromium plated to enhance the appearance of the table and resist corrosion. It is intended' that the present folding table .be movable along a floor, and for the purpose of facilitating such movement the legs are provided with roller means in the form of casters 46.

Assuming that the table is in unfolded condition, that is, with its top sections l5 and I6 coplanar as shown in Fig. 2, although detached from the wall II, the table is supported by the leg'means 26, 35, and 33, and the casters 46.

top sections by a When. in this unfolded relation, the inner pivoted edges of the, sections substantially abut, and since the leg means are connected by the links 42, and 43, which serve as braces, the entire table is exceptionally strong and rigid and will support considerable weight. The table may be readily moved to selected locations by simply rolling it along the floor.

When use of the table is no longer required, it may be stored for future use. In order to conwith their longitudinal ve t a spa ethe table ma be educed to of its axis of rotation are looking bolts 62 which relatively small compass by S mp y fplding its are slidable transversely of the table in bearings roll towardeach other. .Eventually, the sections withdrawn and the table unfolded by reversing to one-half ts ori inal length nd m y be bolts 56 from the guides 53 and roll the unfolded a numbel 0f he ab es m y be stacked one upon Referring now to Fig. 10, it is within the conanothel When a a le 8 to e again Set D for pt of this lnventlon to provide means by which use, It S d d y p y reversing the the folded table may b stored m a Wall closet cedure outlinedabove. 10.
