ing leg structures are Patented Sept. l6,` 1930 Y UNITED STATES vPATENT OFFICE JOSEPH E. WOOD, OF CHICAGO, ILLINOIS, ASSIGNOR TOiTHE DEARBORN COMI'ANY, OF- CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS TABLE My invention relates. to improvements in tables and particularly to'eard tables havingv legs which fold within the confines of the top The object of my invention is to provide a novel structure for supporting the folding le s entirely from the frame independently o the top board of the table.

Another object 1s to provlde a folding leg structure having all of the parts mounted on a supportin member which can be fastened to the table rame as a unit.

A further object is to brace the legs in rigid and substantial relation to the table when in open position and to provide a novel means whereby the braces will automatically interlock with the supporting member as the legs are brought into open position and will automatically release and fold within the table frame as the legs are folded.

Other objects of my invention will appear hereinafter.

In the drawings-- Fig. 1 is a section of a corner portion of a card table showing in perspective the folding leg structure,

Fig. 2 is a. sectional view on the line 2--2 of Fig. 4, j

Fig. 3 is an enlarged detail section on the line 3-3 of Fig. 4, and

Fig. 4 is a bottom plan view of the corner portion of the frame and the folding leg structure, with the leg itself shown in section.

My inventionis more especially adaptedto card tables and therefore is illustrated in connection with a table of this type. The drawings show a portion of one corner of the table together with the folding leg associated with that corner, but is understood that the foldduplicated at theother corners o f the table. The table has a frame A and a to board B. The frame A is preferably m e of wood strips disposed at right angles with relation to each other and joined together at their ends by mitering and gluing to form the corners of the frame. The upper edges of these frame strips have a continuous depressed shoulder 1 to receive the top board B which is fitted in the shoulder to finish .off the edges.' In addition to this the undersurface of the top board has a plurality of small Wooden cleats 2 preferably glued thereto and distributed around the frame. These cleats are fastened to the frame on the inside thereof by nails 3. One of these cleats-2', Fig. 2,

is positioned in each corner of the frame to prevent the'corners of the top board from becoming displaced with respect to the frame. In each corner within the frame I provide a leg supporting member 5 which is in the form of a Hat plate substantially triangular in shape with two of its sides at right angles to each other and parallel to the adjacent frame member B. This supporting member C may be inexpensively made as a metal stamping and its edges are turned at right angles to form flanges 6 and 6 for strengthening the plate and making it more rigid against bending when subjected to the strain of the legs in open position. The supporting member is firmly secured in position in the ycorner ot the frame by the screws 7 which extend through the flanges 6 andinto the frame members B. The supporting member is. preferably positioned in the frame with its top sur- 1 of the frame thus forming an under support for the corner portions of the top board although not fastened directly to the top board in any way. The supporting plate 5 *has a rectangular cutout portion, Fig. 4, so as to fit around the corner cleat 2', and the edges of face substantially in the plane of the shoulder has an inside ear `12v struck up at right angles theretoand an outside earflformedon the side flange Gat thepoint Vopposite the lug'1f2. The earl?,` is ofset'from the flange, Figs.,l2 and'l 4, asfrto yspaceV the leg inwardly al suitable distance from'v the' inner;sidefoffthe frame l..

member B.' Theleg is positioned between the ears 12 and 13 and a bolt 14 is passed through the ears and the leg to form a suitable pivot for the leg. The same flange 6 has another ear 15 formed thereon and spaced from the pivotal point of the leg.

A diagonal brace 16, formed preferably of strap metal, extends between this ear 15 and the leg. It is pivoted at 17 on the ear and has a sliding engagement with a U-shaped keeper or staple 18 on the leg permitting the leg to be swung to open or folded position.4 lVlien the leg is folded within the frame, as shown in dotted lines in Fig. 4, the brace 16 also Swings onits pivot and folds into the frame in the space between the leg and the frame member. The lower end of the brace has a notch V19 which, when the leg is swung to open position, engages one of the legs of the keeper and locks the leg in open position. l'n order to insure the engagement of the notch 19 with the keeper the ear 15 has a stud 2O positioned close to the pivotal point 17 of the brace. As the leg approaches open position this stud is engaged by the brace and applies sufficient pressure to the brace so that when the leg finally reaches its open position the end of the brace will be forced into engagement with the keeper, there being sufficient spring in the parts to cause the brace to snap into engagement with the keeper. Thus the brace 16, in the open position of the leg, rigidly holds the leg against movement in either direction transverse to its pivotal axis.

The supporting member 5 has a portion which lies substantiallyparallel with the frame and is positionedopposite the pivotal axis of the leg and at the point some distance inwardly from the pivot lug, 12 of the leg. This parallel portion has an upstanding flat lug 22 on which is formed an inturned stop lug 23. The leg carries a diagonal brace 24 on the side thereof opposite, the sliding brace 16 previously described. The lower end of the'brace 24 is rigidly secured, Fig. 1, to the leg by means of the screws 25. The brace ex-y tends diagonally `upward away from the leg and its free end portion 26 is bent top a Vertical position so that it lies adjacent to the lug 22 of the supporting member. The free end of the upturned portion 26 of the brace is re` V duced in size, Figs. 2 and 3, and turned laterally parallel to the supporting member 5 to V form anl interlocking member 27. This interlocking memberis oii'set to one side of the longitudinal center of the brace 24 and is adapted, as the leg and brace approach the open position, to be carried into engagement with a keeper lug 28, Fig. 3, which is struck up from the supporting-plate 5. This keeper lug is spaced from the plate member 5 to provide room for the interlocking` member 27 and it is inclined suiiiciently so as to provide'a'wedging engagement for said member 27. The member 27 is long enough to Awardly from the frame member B to straddle thev opening in the plate member 5 formed by cutting the keeper lug from said plate member. Hence it will engage the plate member 5 and will not enter the opening.

It will be seen by reference more particularly to Fig. 3 that when the leg is in folded position the interlocking member 27 is out of engagement with the keeper lug, but when the leg is unfolded the interlocking member 27 will be carried by the movement of the brace into engagement with the keeper lug 28, this engagement being completed when the leg reaches its complete open position. The interlocking engagement of the members 27 and 28 coincides with the locking action of the brace 16 with the leg. The stop lug 23, Fig. 3, lies in the path of the free end of the brace 24 and is engaged by said brace just as the leg reaches its fully open position and serves to prevent the brace 24 from being sprung or accidentally moved out of interlocking' engagement with the member 28. The brace member 24 does not operate as the brace until the leg is swung to its open position and the brace is interlocked with the plate member 5. In this position it does act as a brace to prevent movement of the leg in either direction parallel with the pivotal axisof the leg.

By reference to Fig. 4 lit will be seen that the leg is positioned a suflicient distance inprovide room for the lower end of the folded leg from the opposite corner so that the end of this leg reaches. practically to the frame member and thus makes it possible to obtain the maximum length of leg within the frame.

While I have shown anddescribed my invention in conjunction with folding card tables, it will be obvious that it may be embodied in other types of tables or other furniture, and I reserve the right to make all such changes as fairly fall within .the scope and spirit of the invention.
