Patented May 6, 1930 UNITED STATES JOSEPH SILVEBMAN; OF CHICAGO; ILLINOIS FOLDING TABLE Application filed August 12, 1926. Serial No. 128,738.

This invention relates to improvements in furniture, more particularly to an improvedv table having legs connected thereto and adapted to be folded up under or against the l top'of the table and its objects are the provision of a generally improved and simplified construction that may be economically produced and a simple and inexpensive connection which will permit easy and convenient opening and folding of thelegs and which Will lock the legs in extended and folded positions and hold same firmly and rigidly in either of said positions.

The invention is illustrated in the accom 5 panying drawing in'which:

Figure 1 is a vertical longitudinal section through a table embodying the presentinvention on the line 11 of Fig. 2;

' Fig. 2 is a bottom plan view of. the table showing the folded positions of the legs in dotted lines; a V

Fig. 3 is a detail section-taken on the line 3-3 of Fig. 2; r

Fig. 4 is a detailed cross section taken on the line 44 of Fig. 3; and r Fig. 5 is a fragmentary section showing a modified form of connection between the legs and the top of the table.

. Referring now to the drawing, the particular embodiment of the invention selected for illustration comprises atop 5 shown of generally rectangular configuration although its shape is immaterial and may vary as desi ed. J i

The top .5 is supported, in'use, by two pairs of legs 6 and 7, with one pair of legsat or near each of the opposite ends of the top 5 and with one leg at or near each of the four corners of the top 5.

The legs 6 are connected together by an end piece 8 which extends between and is suitably secured at its opposite ends to the upper ends of the legs, to lie adjacent the top 5 when the legs are extended or opened for use.

' 4.5 The legs 7 are similarly connected by an end piece 9 which is similarly disposed at the opposite end of the table when the legs 7 are extended for use. i

The upper ends of each pair of legs are hinged to the top 5. The particular hinge connection, may of course, vary as desired. In the embodiment of the invention shown, a pair of fastening pieceslO are secured transversely across the under surface of the top 5, one along the inner sides of each pair of legs I 6, and 7 These fastening pieces 10 may be secured to the top 5 in any suitable or preferred manner and the hinge connection be-: tween the top 5 and each pair of legscomprises a pair of hinges 12 each having a leaf secured as by screws13 to the adjacent fastening piece 10 and its other leaf similarly secured to the adjacent side of the leg.

The connections between the top 5 and the legs 6 and 7 of the table are designated generally at 15. Each comprises a metal rod 16 extending between and secured at its opposite ends at 17 in the pair of legs with which it is associated. A second rod 18 also preferably of metal, although these details may of course vary extends from substantially the center of each rod 16 and normal thereto towardthe opposite end of the table.' The rods 16 andl8, which may be tubular as shown or solid, for each pair'of legs are joined byfsuitahle T unions 20 and the free end of each rod 18 has.

telescopic engagement in a tube or sleeve 21, also preferablyof metal although this too may vary.

In the embodiment shown, in Figures 1 and 2 the adjacent or inner ends of the tube or sleeve members 21 are flattened together at 22 and pivoted at 23, between a pairfof angle members 24, secured at 25 substantially centrally to the under surface of the top 5. The angle members 24 form in effect-a common bracket pivotally joining the. connections for both pairs of: legs to the top 5.

Secured at one end to each of -the tube or' sleeve members 21 as shown at 28, isa leaf spring 30 or a clip or strip biased toward the sleeve 21 to which-it is secured and normally lying along and snugly against the same. Near its opposite or free end each spring or strip 30 has a pin, stud or projection 32 normally urged by the inherent springiness of the strip through an opening 34 in the tube or sleeve member 21 and whenthe legs are extended for use into an opening 35 in the r d 18- Th v mgage nen1:of t epi 2 n the opening 35 looks the legs firmly and rigidly in open or extended position for use, and the tube or sleeve members 21 completely encircling or embracing the rods 18 hold the legs firmly against all directions of relative movement. At the same time, the telescopic engagement provides a' simple and inexpensive connection which is operated with ease and convenience.

Each rod 18 is provided With a second opening 40 into which the pins 32 are automatically projected upon closing or folding up of the legs into the dotted line positions shown, the pins whenengaging in the openings 40 looking the legs firmly andrigidly in folded or collapsed position.

the pins 32 from the openings 35 or 40, the

, free ends of the strips or spring arms 30 are preferably extended beyond the pins 32 and are offset out at 42 to be conveniently grasped by the fingers for the purpose of pulling the pins from the openings 35 or 40 as the case may be. To fold up the legs all that is necessary isto spring the pins 32 out of the openings 35 and to then swing the legs up into folded position about the hinge connections 12, the pins 35 being automatically projected into the openings 40 as the legs reach their folded position. Infolding and extending the legs, the rods 18 have telescopic sliding movement within the tube or sleeve members 21 and are held firmly in position in all directions.

In the embodiment of Fig. 5, the tube or sleeve members 21' of the connections 15' are pivoted at 23 in separate brackets 24 which may be' spaced as desired to meet any particular table construction.

As shown in Figs. 2 and 3, the rods18 may be secured in the T-unions 20 by pins passing diametrically through the rods 18 and through the surrounding portions of the unions 20. p p

In swinging thelegs into open and closed or folded positions, the ends of rods or rail members v16 may befree to turn in the legs or theT 'unions 20 may be free toturn on the-rods"16 to permitthe relative angular movement which takes place. In addition the rods 16 provide a reinforcement between the legs and increase the "strength of the one pair of legs table'comprising a top with table and having parallel depending flanges with an intervening space directed longitudinally of the table, a pair of rods one pivotally connected with each pair of legs, a pair of hollow rods both disposed wholly in a plane longitudinally of the table, one of said hollow rods telescoping over each of said first rods and said hollow rods having adjacent ends 1 flattened and having fixed pivotal attachment between the depending flanges of said bracket means, an externally exposed leaf spring anchored at its upper end to the outer side of each of said hollow rods with its free endolfset'outwardly and terminating adjacent the end of the hollow rod to be engaged and sprung out .by the finger, said spring having an inwardly projecting detent pin between its anchored and offset ends, and said first rods each having a pair of openings engageable with said pin in the open'and said cross rods, a second pair of hollow rods each disposed wholly in a plane longitudinah ly of the table, one of said last rods telescoping over each of said first hollow rods and said last rods having adjacent ends flattened and having fixed pivotal attachment between the depending'fianges of said bracket means,

hollow rods each having a pair'of openings engageable with said pin in the open and folded positionsof said legs. o

In witness whereof, I hereunto subscribe my name this 9th day of August, 1926.
