Peters, Seattle, Wash. Application July 27, 1935, Serial No. 33,571 Renewed June 7, 1938 2 Claims. This invention relates to a novel and improved foldable card table of the portable domestic type now generally used in the home and appropriate places of public amusement, and it has more par 5 ticular reference to a structure characterized by a distinctive top and a proper coinciding collapsi ble leg support. The improved table construction is character ized by a new and improved duplex leg frame sup port having expeditiously usable and satisfac torily performing adjusting and retention means for the leg frames. Speci?cally, novelty is predicated upon the adoption and use of U-shaped pivotally mounted 15 leg frames positioned on opposite sides of the under surface at the top wherein said frames are provided with self-adapting stay units slidably cooperable with latch equipped means carried by the under side of the top, said features being particularly designed and coordinated to insure efficient and dependable results. .Though of a collateral nature, the improved construction is further individualized by the em bodiment therein of a unique charted top of a 25 predetermined diagrammatic nature whose fea tures contribute in providing as an added fea ture, a gameboard susceptible of practical usage for playing checkers, cribbage and similar games 30 of chance and skill. Then too, the embodiment adopted possesses in addition to ornamentation and features of design, conveniently located corner openings to accommodate temporarily usable service acces sories such as ash trays, drinking glasses and simi 35 lar utensils so frequently needed by the particip ants and guests. Other features and advantages will become more readily apparent from the following de 40 scription and drawings. In the drawings: Figure 1 is a bottom plan view of a folding card table with the legs folded showing to advantage the particular novelty hereinafter claimed. Figure 2 is a substantially central sectional view through the table with the leg frames down in supporting positions. Figure 3 is a central longitudinal section of a fragmentary type taken on the plane of the line 3-3 of Figure 1. Figure 4 is a perspective view of one of the leg 50 frame stay members. Figure 5 is a detail sectional and elevational View of one of the spring pressed detents or latches. The table top, which is preferably of wood or 55 (Cl. 311-87) some composition light-weight material is in dicated by the numeral 8. It is of conventional proportions and preferably rectangular in top plan View. Surrounding themarginal edge or perimeter is a correspondingly shaped rim made up of the edging strips 9. These are of duplicate wood construction and are suitably secured in place to be flush with the playing surface and to project below the underside to provide the de sired apron-like effect shown in Figure 2. By 10 preference the upper edge portions of these strips 9 are rabbeted or grooved to form ledges to ac commodate the edge portions of the top or board 8. Moreover, as shown in Figure 1 the abutting ends as indicated at it are of desired curvature 15 so as to form a portion II of the circular corner opening of hole l2. The remainder of this hole is formed by a correspondingly curved edge por tion l3 of the complemental corner blocks l4 suit ably fastened to the underside of the table. These corner blocks are provided with bearing holes I5 to accommodate the trunnions or journals on the ends of the cylindrical bar member I6 of the leg frames. The legs are differentiated by the numer als I‘! and are arranged in pairs and are foldable in superimposed relationship when not in use as shown in Figure 2 and obviously the legs are pro portioned so as to permit them to swing within the area of the rim surrounding the marginal portion of the top. The con?guration of the legs 3O may be of any appropriate design to provide for symmetry and balance in appearance, as well as in utility. In the arrangement shown in Figure 2 the leg frames are arranged in opposed parallel ism and are swingably mounted between the re spective or complemental sets of corner blocks l4. Thus, when the table is held up with its underside facing the floor the legs have a tend— ency to swing out and down by gravity to open or unfolded positions. I call attention at this time to the rail l8 fast ened centrally to the underside of the top. This is located centrally between and parallel to the legs ll’ of the respective frame. Then as shownv in Figures 2 and 3 it is provided with longitudinal superposed parallel grooves or guideways I9 and 20. The inner ends of the grooves overlap and are formed with depending lateral end notches 2| which function as keeper seats. These keeper seats are adapted to accommodate the straight across bight portions 22 of the substantially V shaped stay units 23. The diverging arm por 35 40 45 50 tions 24 terminate in outbent pintles 25 pivotally connected with the complemental legs. It is evi dent therefore, that the portions 22 of the units 55 2 2,124,007 23 ride in and out in the guideways or grooves l9 and 20 and when the legs are spread apart, the portions 22 drop down into the keeper seats 2|. To guard against accidental displacement when the table is set up for use I have found it ex pedient and practicable to associate with each keeper seat a latch or catch. This comprises a cylinder 26 set into a socket having a ?ange 21 at the open end, which ?ange abuts the outer end 10 of the socket and serves as a sort of a wear plate for the coacting portion 22 of the coordinated unit 23. Located in the cylinder is a coil spring 28 which forces a plunger 29 out, said plunger being provided with a ball-head 30 performing the dou~ 15 ble function of a retention element and cam. In cidentally, the open end of the cylinder 26 at the point where the ?ange 21 joins is struck in to provided an annular shoulder to limit the out ward sliding movement of the plunger 29 as 20 shown in Figure 5. By placing the cylinder as shown in Figure 3, the cam head 3G partially bridges the entrance to the keeper seat 2| and is thereby properly located to provide the requisite snap action. It is evident, however, that any 25 other suitable type of a catch may well be em ployed. The one shown is desirable in that it recedes to allow the trip or bight portion 22 of the unit 23 to conveniently snap into the keeper seat 2!. Also, the cam coaction between these 30 features permits this trip 22 to jump out from the seat 2| by putting a slight manual pressure against it through the medium of the legs. Or stated otherwise by turning the table frame up on one edge and then catching hold of the two leg 35 frames they can be moved readily toward each other and this slight inward movement auto matically releases the stay devices 23 so that they can slide to proper collapsed or folded position. As thus far described’ it will be seen that the 40 principal structural novelty resides in the spe cially designed corner blocks I4 serving as sup ports for the journal equipped ends of the rocker shaft portions I 6 of the complemental leg frames. This is one feature of construction. secondarily, the use of the opposed leg frames mounted in this way together with the slotted bar or rail I8 and the swingably mounted wire stay devices 23 is an additional improvement. More speci?cally however, the idea of the spaced parallel super posed slots [9 and 2|] with the keeper seats 25 at the inner overlapped ends and the associated spring catches and stay devices 23 is of utmost importance. Referring again, and brie?y, to the aforesaid corner holes l2, these function as pockets for the reception of water glasses, ashtrays and simi lar accessories especially constructed to ?t into said holes. Though it has no particular connec tion with this invention it might be stated that 60 these various service accessories (not shown) are to be made of disposable material such as paper or the like for economy and convenience and by constructing the table to accommodate such ac cessories this adds further to its special adapta~ catches and the self adapting wire yokes or stay devices 23 it is to be observed that a table of this construction may be substantially made of wood or some equivalent light weight sturdy stock. This permits the manufacture and sale of a more or less rigid Warp-proof structure always insur ing e?iciency of use and obviating the presence on the corners of metal cleats and the like such as are so frequently objectionable in tearing one’s clothing. 10 Minor changes in shape, size and rearrange ment of details coming within the ?eld of inven tion claimed may be resorted to in actual prac tice, if desired. Having thus described the invention, what is 15 claimed as new is: 1. A portable foldable leg structure card table of the class described comprising a table top hav ing a marginal depending rim, duplicate blocks attached to the underside of the table top and associated with the corner portions thereof and connected with the adjacent surfaces of said rim, said blocks being of a thickness corresponding to the depth of the rim to provide the desired flush formation between the lower edges of the rim 25 and bottom surfaces of said blocks, a pair of dup~ licate U-shaped leg frames, said blocks being pro vided with socket forming bearings, the adjacent ends of the bight portions of said U-shaped leg frames being provided with trunnions, said trun 30 nions being journaled for oscillation in said bear ing sockets, the leg members of said frames being swingable into overlapping relationship in a man ner to permit the frame, when folded, to be con ?ned with the depth of the surrounding marginal 35 rim, the combined thickness of the overlapped legs being substantially equal to the thickness of said blocks, and slidable stay units pivotally at tached to the respective legs of said leg frames and cooperable with said table top. 40 2. In a structural assemblage of the class de scribed, a table top provided on its under side with a longitudinal rail, the ends of said rail ter minating in spaced relation from adjacent mem bers on the marginal portions of said table top, 45 said rail having a central longitudinally elongated notch formed in that face abutting the under side of said top and said notch constituting a guideway, said rail being further provided with a longitudinally elongated slot forming a second 50 guideway, one end portion of the slot underlying the major portion of said notch, one end of said notch being formed with a counter-notch, and one end of said slot being provided with a corre sponding counter-notch and said counter-notch 55 es constituting keeper seats, a spring-pressed, cam-equipped latch associated with each keeper seat and cooperable with the entrance portions of the keeper seats, U-shaped leg frames hing edly attached to the top and provided with sub 60 stantially V~shaped stay units, the inner ends of said stay units being con?ned in the afore mentioned guideways for cooperation with the keeper seats and latches. tion for home use.
