Patented Sept. 1, 1931 Nrro STATES PATENT OFFICE GUY C. DAVIS, OF RQOKFORD, ILLINOIS, MID; DONALD G. GRISWOLI), OF LOS ANGELES, CALIFORNIA, ASSIGNORS OF FORTY PER CENT TO SAID GUY C. DAVIS, OF ROCK FORD, ILLINOIS, AND" CITY, ILLINOIS FOLDING TABLE AND BENCH This invention relates to folding furniture generally, but is more particularly concerned with an improved folding table and bench to form a luncheon set suitable for camping or outing use, although adapted likewise for use in the home or in lunch rooms or other places wherever a compact, strong portable folding outfit of this kind may be desired. The principal object of our invention is to provide a table and bench which can be quickly and easily set up ready for use and just as easily folded to be set aside or stored away and which, when unfolded for use, is extremely strong and rigid to give good service, and is arranged to fold to an extremely compact size such that the table and bench, or two benches as the case may be, will take up very little room. For example, the set when packed, may be clamped flat on the running board of an automobile or maybe clampeclon the running boardinsuch a position that it will serve the purpose of a luggage carrier.

,Among the features of our invention may be enumerated the following: (1) The provision of a folding table and bench or bencheswherein the table top is.

formed by two leaves hinged together to fold onto one another or to be disposed side by side, each of the two leaves of the table top being. preferably 'ofthe same size as the top for the bench or benches so that when the outfit is folded and packed, it makesa compact and symmetrical bundle easy to handle.

(2) The provision of the table and bench or benches having the tops thereof grooved longitudinally on the underside thereof for reception of the folding legs and struts therefor whereby to enable the folding of the table to the smallest possible size, namely, that of a half of the table top'itself and likewise, the folding of the bench to the smallest possible size, namely, that of-the top thereof.

(3) Theprovision of a'table, the top of which is formed, as stated above, by the unfolding of two leaves hingedly joined together, and having criss-crossed legs'at opposite ends thereof with struts extending from the imderside of the table top to the intersections of the cries-crossed legs to make for rigidit the strut for one end extending from the one leaf'adjacent the hinges connecting the two leaves to the intersection of the one pair of legs and the other strut extendingi-from' the other leaf adjacent the SIXTY'PE- R CENT mo HAROLD L. OFFENHISER, OF PEARL 1 hinge connections between the leaves to the intersection of the other pair of legs whereby to avoid having too much of the load borne by the hinges themselves and also prevent the top from sagging or buckling at the middle thereof.

(4) The provision of a table and bench or benches, the folding legs and reinforcing struts "of whichare joined to the top pieces by universal joint connections affording the desired range of movement for the legs and struts with reference to the top pieces to enable the criss-crossing of the legs and the coupling and uncoupling of the legs and struts, the said universal joints being of extremely small'size, yet made in such away as to afford the requisite strength.

'(5) -The provision in connection with the coupling of each pair of crisscrossed legs with its strut of a latch arranged to be slid into and out of locking position engaging beneath the head ofa stud pivotally mounted on the end of the strut and entered through registering holes in the criss-crossed legs, the said latclrbeing formed on the outside facethereof to make wedging engagement with thehead of the stud and thus minimize any danger of the connection workingloose and permitting collapse of the 'tableor bench.

The invention is illustrated in companying drawings, whereine- Figure 1 is a perspective view showing theitable almost completely folded, the completely folded condition being represented in dotted lines;

The table top 10 is made up of two boards A and B hinged together on their underside, as indicated at 11, so as to fold onto one another, as indicated in dotted lines in Fig. 1, and unfold into position alongside one another, as shown in full lines in Figs.

1 and 5. The bench top 12, or rather, each bench top, inasmuch as two benches may be provided in connection with one table, is made from a single board C. The boards A and B are of equal size and of the same size as the board C so that they are all arranged to fit neatly in a carrying case 13, shown in Fig. 3, made of canvas or other suitable waterproof material and having a flap 14' for closing one end thereof provided with snap fasteners 15, and having the handle 16 at a mid point thereon for the carrying thereof. The fact that the boards are of the same size makes the bundle of a symmetrical form, easier to handle, and easier to clamp onto the running board of the automobile, if that is desired. The legs and struts for the table. and bench are all pactness is arrived at; the table reduces to the size of the two superposed boards A and B forming the top 10, and the bench reduces to the size of the board C forming the top 12 thereof. 'This and other features of construction embodied in the improved table and bench of our invention is fully described hereinafter. a

The bench and table are of substantially the same construction, the only difference being that the table has the top 10 made of two leaves hinged together as described above. A description of the table will,

-therefore, serve'largely as a description of the bench, too. At the outset it will be noted that the table has a pair of legs 17 and 18 at one end thereof fastened by means of universal joints 19 to the underside of the boards A and B permitting the legs to be criss-crossed, as shown in Fig. 5. A strut 20, also fastened by means of a universal joint 19, has a stud 21 pivotally mounted on the free end thereof by means of which the same is arranged to be coupled with the cries-crossed legs 17 and 18 at the point of intersection, as will presently appear. Similarly, the other end of the table has a pair of legs 22 and 23 fastened to the boards A and B respectively by joints 19 and, cooperating with these legs, a strut 24 fastened by means of a joint 19 and equipped with a stud 21 on the free end thereof to couple the strut with the criss-crossed legs 22 and 23 at the point of their intersection. The legs 17, 18, 22 and 28, together with their joints 19, are all arranged to fit snugly in longitudinal grooves 25 cut in the underside of the boards A and B, these grooves extending for a good part of the length of the table, as shown, to accommodate the full length of each legso as not to leave any part projecting. Similarly, the struts 20 and 24, to gether with their joint 19, are arranged to fit snugly in shorter grooves 26 provided therefor in the boards A and B. So much for a general description of the type of construction employed. Before proceeding to a detailed description of the various structural features, it will be observed that the bench has a similar complement of legs 17, 18, .22 and 28' and struts 20 ad 24', the legs and struts being all fastened by means of universal joints 19 and the struts being equipped with studs 21 on the free ends thereof, and the legs being arranged to fit in grooves 25 and the struts in a groove 26 provided in the underside of the board C. Obviously, the crisscrossed legs, coupled with the struts, afford a very rigid support for the top 10 of the table or the top 12 of the bench. In the case of the bench where the top is in one piece, there is, of course, no difiiculty in obtaining the desired rigidity, but in'the case of the tab-1e, the fact that the top is formed by two leaves hingedly joined together necessitates proper disposition of the struts to avoid having too much Of lJlIG load being borne by the hinges 11, as well as to prevent sagging or buckling of the table top at the middle and, in that case, it will be observed that we have fastened one strut 20 onto the board A on one side of the hinge connection between the boards A and B, and have fastened the other strut 24 onto the board B on the otherside of the hinge conection. Thus the strut 2O assumes the load imposed on the board A at the middle of the table top which'would otherwise be transmitted to the hinges l1, and the strut 24 assumes'the load imposed on theboard B at the middle of the table top'which would otherwise be borne by the hinges. It is found that with this arrangement of the struts, the table top is kept quite rigid and will not tend to sag orbuckle at the middle thereof. I 1

The -legs and struts for the table and bench, or benches, are all preferably made from channel iron strips cut to the proper lengths, this material affording the desired rigidity and strength even though strips of relatively small cross-section and proper tionate light weight are used, and, of course, that is. of great importance in a portable outfit of this kind where compactness and light weight are especially desired. The free ends of the legs are cut off diagonally, as shownat 27, to afford good footing. This kind of material also lends itself particularly well to the connection of the legs and struts with the boards A, B and C by means of the universal joints 19, and also makes it a simple proposition to pivotally mount the studs 21 on the free ends of the struts 20, the parallel flanges of the channels being taken advantage of in both cases, as will now be described. 7 Considering first the connections between the legs or struts and the universal joints '19, it will be apparent that a description of one of these connections will sufiice for all. Refer to Fig. 6. In this figure it will be observed that the universal joint 19 comprises a strap 28 fastened as by means of screws 29 in a recess 30 adjacent the endof the groove 26 wherein the strut 20 is received,

.the strap 28 having the one end thereof bent at right angles, as shown at 31, to project into the end of the'groove 26. A U- shaped connector or intermediatev member 32, which is preferably formed between dies from a piece of sheet metal, has the parallel arms thereof fitting between-extensions 33 of the flanges of the channel strip from which the strut 20 is formed,'and is pivotally connected thereto by means of a pin .34 passed through registering holes in the two parts referred to. pin 34 areupset, as indicated at 35,,to make apermanent connection. The extensions 33 are formed by simply cutting away a part of the web of the channel at the end of the strip, as indicatedat 36. The connector 32 is pivotally mounted on the inturned end 31 of the strap 28 bymeans of a rivet pin 37, the latter affording pivotatmovement for the connector 32 about an axis at right angles to the pin 34. Thus the struts, or the legs, for that matter, are free to swing about a horizontal axis, due to the pin 34, to a position at right angles to the table top or bench top as the case maybe, as indicated in dottedlines in Fig. 7, or. to a position making an acute angle with-the top.- Fur- The. projecting en'd's of the thermore, each strut. or .leg has freedom forswinging movement laterally, due to the pin, 37, so that the legs for the table, or bench, as the case'may be, can be disposed criss-crossed, and the struts 20 and 24 for the table can be swung sidewise suflicient to make connection at their free ends with the criss-crossed legs at the point of intersection of the latter. Needless to say, the universal joint just described is of extremely small size but is still neverthelessof ample strength. The fact that the parts 28 and 32 can be formedfrom sheet metal between dies and these parts can be fastened together by rivet pins, cuts thecost down to'a minimum.

The studs 21 have, connector yokes 38, similar in form-to theconnectors 32, by means of which the; same are pivotally. mounted on the .free ends of the .struts 20, 24, 20 and 24 (see Figs. 9 and 10). The connector 38 is substantially U-shaped and formed from sheet metal between dies like the connector 32. The parallel arms thereof fit between extensions 39 of the flanges of the channel strip from which the strut is formed, the extensions being provided by simply cuttingaway a portion of the web at the end of thestrip, as shown at 40. A rivet pin 41, passed through registering holes in the two parts, serves topermanently join the same. The stud 2l,.which-is,annularly grooved at the outer end;thereof,-as shown at 42, to provide a fiat head 43, has the inner end thereof reduced, as shown-at 44, for extension through a hole in the connector 38 to permit the fastening of the stud 21 to the connector by upsetting ofthe reduced end of the stud, as shown at 45. 0b. viously, this construction makes for strength and economy as: well. The stud 21, by reason of its pivotal mounting on the endof the strut, can be;passed through registering may he slid into and outof locking position.

A rivetv pin 49, entered through a slot 150 in thelatchi47, provides a permanent mounting for the latch 47 on one of thecrisscrossed legs, and at'the same timeserves as a guide for the latch in the-sliding thereof to and fro. A slot 51 is punched in the end of the latch 47, permitting the latch- ,to straddle the projecting end of the stud 21 in. the groove 42 thereof. .The' end ofthe latch is iii preferably slightly tapered, as indicated at 52, so that the outside face of the latch will make Wedging engagement under the head 43 as the latch is forced home. Thus there is no likelihood of the coupled parts Working loose and possibly permit collapse of the table or bench. There is enough leeway afforded by the taper on the end of the latch to insure a tight connection even though the cooperating parts may become slightly worn. It should be evident from the foregoing that the table and bench can be removed from the carrying case and set up ready for use in a couple of minutes, and that it is an extremely simple matter for any mechanically unskilled person to handle the same. Furthermore, there are no loose parts that are apt to be lost or mislaid, which, of course, is a decided advantage. The economical construction of the outfit makes it a sound investment despite the fact that most people will only get occasional use out of it. The lightness and compactness of the outfit is of advantage not only from the standpoint of the user but likewise from the standpoint of the manufacturer, for it permits shipment of the outfit by parcel post. It is believed the foregoing description conveys a clear understanding of the various objects and advantages of our invention. \Vhile the specification has been confined "to a folding table and bench, it should be understood that those are only two embodiments of our invent-ion and that various other articles of furniture may be made employing substantially the same construction, as for example miniature tables and benches for childrens use, foot stools, radio benches, sewing tables, card tables, banquet tables, and other articles of a generally similar description.
