6 Claims.

Thisinvention relates totfurniture construction and more particularly to new and useful improvements which have been incorporated in the folding table which is hereinafter described andillustrated.

An-object of the invention is to produce for the general public, afolding article of furniture such, for example, as 'asturdy and compact foldingtable, whose minimum numberof parts and simplicityof production and assembly makeposjsible the .use of mass-production methods in its maufacture.

Another-object-of theinventionisito produce a utility folding table whose light weight, ,eaSe' of operation, and fold-away -features, make it an ideal piece of furniture for any :home and "for countless uses, the foremost :of which are: card table, coffee table, serving table, garden table,"

et cetera.

A third object :of the invention is. to-producea folding article of furniture which, by virtue of its unique mechanical principles and operation, automatically locksthe two halves of the'top 'or superstructure together and tends to bring "their underneath surfaces into close contact with the 13 With the ioregoing .and other objects in view,

the invention relates to anew construction and combination of parts. in folding tables, arranged according to the novel principles and mode-of operation and assembly as herein explainedgas well as shown in the accompanying drawings which illustrate a ,preferred form or example of the invention with its several uses and advantages, wherein: Figure 1 represents a table embodying theprinciples of my invention .as seen from one side, in its unfolded position.

Figure 2 is an end view of the table.

Figure 3 illustrates the first step'infoldingthe table-that of lifting the outer edges of the two halves of the top piece. The table is seen from the same view as'that in "Figure l;but in reduced scale.

Figure 4 represents'the table when completely folded as seen from the same end as f-in'Eigure-2;-

perspective as viewed from the upper side of the table. "The two top pieces are indicated by phantom lines'to better show the arrangement of the cleats and legs.

To. explain the construction and operation of the table in greater detail: the superstructure, or supporting surface of the table, is in any suitable shape "andis divided laterally in a line parallel with the axis formed by passing a line through I the points of intersection of the two pairs of X- type .legs, thereby "formingthe top pieces I and"2, whoseinboard edges abut one another when'th'e table'fisrin itsunfolded position. By means of a smalldowel 1B "which projects perpendicularly outfrom the midpoint of the inboard edge of top piece .2, and .whi'clrfits snugly into a hole l9 made to receive fitin the inboard edge of top piece I, perfectialignmentof the'two top pieces is attained and absolutely all lateral movement between the two-top pieces is eliminated. Each half of the top piece is firmly secured to the fixed or inner end portions of the upper edges of a pair of cleats-or runners, whose opposite free or outer end portions are, in turn, pivota'lly secured by means of countersunk flat-head machine screws tor other suitable pivotmean which will leave the inside surfaces of the legs in either pair absolutely'flat) to the "upper-ends of the two legs whose-upper portions lie beneath and help support the opposite top piece. Thus, as seen especially'well in Figures 7 and 8, top "piece I is seouredto cleats and'9, the opposite ends of these cleats being pivotallyattached to legs -3 and 5,at point-s H and 13, respectively. Similarly, top piece ;2 is secured to cleats 8 and it, and the opposite ends of these cleats are pivotally attached to l'egsidtandfi atpoints I 2 and M, respectively,

The arrangement of cleats and legs in this manner, therefore, provides a substructure or support for the top pieces not only at the four points where the tops of said legs make contact with said :top pieces, but 'at all points on lines extending betweenithe tops of legs'3iand 4, and between the "tops of legs 5 and 6.

Cleats and "9 are secured to the undersideof top piece I, and cleats 8 and it! aresecured to'the underside of itoppiece '2, in such manner that all cleats-are parallel to one another and :at right angles to the longitudinal axis of the particular top piece to which they 'aresecured. The other The four legs are arranged in pairs of X-type,

each leg being outwardly flared at the lower portion thereof, and each pair of legs being foldable about an axle, or cross stretcher-bar [5, which extends from point it where legs 3 and 4 cross, to point 11 where legs 5 and 6 cross. In addition to providing an axle about which all four legs may rotate, the cross stretcher-bar maintains the correct distance between the two pairs of legs, and by means of an insert bushing and an adjustable nut and washer on each pair of legs, the legs are held in close contact with one another at their point of intersection.

The operation of folding the table from its position of use to its position for storage is done in the following manner: top pieces I and 2 are grasped by their longest outside edge and lifted up a few inches (Figure 3) Simultaneously, both top pieces are pulled apart until their inside edges have cleared the free ends of the cleats and the tops of the two legs upon which they normally rest (Figure 5). Both top pieces may then be rotated downwardly until they come in contact with the bottom portions of the four legs. By further applying slight pressure, the legs fold into alignment with one another and lie in close parallel position to the two pairs of cleats the outwardly flaring portions of the legs supporting the device in upright or standing position, while the top pieces assume a position substantially parallel to the folded legs; all of which is shown in Figure 6. The operation of unfolding the table is a mere reversal in sequence of the folding operation. A handle is secured to the underneath surface of the inboard edge of one of the top pieces for ease in carrying.

It should also be pointed out that the design of this table eliminates the wobble inherent in practically all other folding tables, by providing exceedingly large bearing surfaces between the various legs and cleats at the points where wobble is most liable to occur (namely, points H, l2, i3, l4, l6, and I'D, and, further, by using lowtolerance metal fittings in the pivotal joints. In no instance is there a threaded metal surface bearing against wood, therebyinsuring a permanent tight fit in all six points of bearing and friction in the table.

In view of the aforementioned unique features of construction and operation incorporated in this table which is illustrative of my invention, the following claims are made:

1. A foldable article of furniture comprising; a top piece of any suitable shape, which is composed of two halves and which forms a supporting surface, or table; four cleats, arranged in parallel spaced pairs, with one pair of cleats being secured to the underneath surface of one of the top pieces and projecting beyond one edge thereof, and the other pair of cleats being secured to the underneath surface of the other top piece and projecting beyond one edge. thereof; and four legs arranged in pairs of 'X-type, with each pair pivotable at the legs mid-point about a common axle which also acts as a stretcher-bar between the two pairs of legs, a leg of each X-type pair of legs being pivotally connected to the projecting portion of a respective cleat of one pair of cleats, the other leg of each X-type pair of legs being similarly connected respectively to a respective cleat of the other pair of cleats, in such manner that all legs and cleats are adapted to fold into close-fitting parallel position, with each pair of legs lying flush between the edges of the cleats to which said legs are attached, and with both top pieces lying in a substantially parallel position relative to the folded legs.
