FOLDING LEG FOB. 'TABLES AND THE LIKEi Application led March 19, 1928. Serial No. 262,734.

This invention relates to folding tables and more particularly to tables such as card tables having supporting legs which are adapted to be folded from operativef extended position 5 to inoperative folded position adjacent the under side of the to The principal obJectof the invention is to provide a'folding leg structure in which the leg,- when in extended position, will be op- -m erativeto rigidly support the table in position for use, and. which structure will permit the leg to be readily swung to' folded position lclosely adjacent the underside of the table top to facilitate storing of the table I5 when not in use. Another object of the invention is to provide a folding leg construction which is, simple in construction, and which does 'not detract from the general app' pearance of the table.' It is also an object of 2o thepresent invention to provide a folding leg structure which is opera-tive to retain the `leg in folded position as well as in extended position.

l Other objects and advantages of the invention will be understood by reference -to the following specification and accompany'- ingdrawings in which I have illustrated a part of a card table having a folding leg construction embodying one form of my invention.

In the drawings:

Fig. 1 is a bottom plan, the leg being Yshown i in section.` Fig. 2 is a section` on the line 2-2 of Fig. as 1, and

:Referring now to the drawings, myl improved Jcard table construction includes a side rail or supporting frame member 10 4o ery of the table-top 11. Brackets such as shown at 12 are secured to the frame 10 by any suitable means, for example, by welding, and the horizontal ange. or shelf portion 13 of the brackets are slotted as shown at 14, to receive a screw 15, which extends through the slot and vinto the card table top, thereby to fasten the top to the frame. .flThe frame 10 is preferabl' formed of a tubular metal member; whic may be co1- Fig. 3 is a section on the line 3 3 of Fig. 2.

which preferably extends varound the periph-v lapsed to form a double thickness substan. tially flat member as clearly shown in Fig. 2, suitable ornamental beads being provided as shown at 16 and 17. The frame may alsobe formed of sheet metal bent to form the desired shape. n Thetop 1l is preferably made of a three ply wood panel board 18 in which the layers of Wood are arranged with the grain extending in crosswise direction relative to each other so that the panel board will not readily warp and will 'be of ample strength to serve its purpose. A'layer of padding material indicated at 19 is spread over the topgsurfacel of the panel board and provided with a suitable covering 2O of iiexible material such as fabricoid. y r

For supporting the table top, I' 'rovide tubular metal legs, one of which is s own at 21, and which may be provided with beading or other ornamentation, as shown at 22.v The leg 21 is pivotally connected to the'top by means of a bracket 23 which includes a pair. of spaced

ar'ms

24 and 25 which embrace the upper end portion of the le The bracket 23 75 is secured to the frame preferably by welding as shown at 26, and a pivot pin 27 extending through the

arms

24 and 25 and substantially "diametrically through the upper end of the leg,is provided for ivotally mounting the leg in the bracket. t will be apparent -that the leg maybe swung from operative or ex- -tended posltion as shown in full lines in Fig.'`

2, to folded or inoperative position closely adjacent the under side of the table top as shown y 1n broken lines in Fi 2. i

For maintaining the leg in extended Osition, I provide a spring actuated lock w ich includes a bolt or cross pin 28, which extends substantially diametrically'through the post' and is movable lengthwise of the leg in slots 29 and 30, which: are provided in the leg. The bolt 28 is yieldingly urged in an upward dimaciliion by means of a compression spring 31 which is compressed between lthe under 95 side of the bolt as shown at 32 and the bottom 33 of a tubular member 34. The tubular mem'-A 1 ber is slotted as shown at 35and 36 to permit the bolt 28 to extend therethrough and to move lengthwise of the tubular'member and the upper end of the latter is pivoted on the pivot pin 27, about which the leg swings.

It will be apparent that the leg and spring enclosing tubular member 34 may be swung as a unit about the pivot pin 27, the bolt 28 also swinging about the pivot pin in accord- A ance with the movement of the leg. The

arms

24 and 25 of the bracket member are notched as shown at 37 in Fig. 2, to receive the ends of the bolt 28 which project outwardly from opposite portions of the leg 21. The spring 31 is obviously effective to cause the bolt 28 to enter the notches 37 so as to establish interlocking engagement with the bracket, thereby to prevent theleg from swinging about its ivot.

A sleeve 38 is slidably mounted on the leg 21, and is secured to the locking bolt 28 by any suitable means such as welding, as indicated at 39, thereby to afford' convenient means for moving the bolt 28 against the pressure of the s ring 31', thereby to disengage the bolt from t e notch 37 in the bracket. The leg may then be swung about its pivot to folded position where it may be maintained by providing a relatively shallow notch 40 in each of the arms of the bracket member,

which notch will be effective to receive the ends of the bolt 28 in substantially the same manner in which/the notch 37 receives the said ends. The sleeve `38 may be provided with ornamental beading as clearly shown in Figs. 2 and 3, so as to improve the general appearance of the table structure, and also so as to afford a more secure grip on the sleeve for facilitating disengagement of the interlocking parts.

By providing the above described form of sprin mounting, Iam enabled to use a spring of suc a length and strength that it will provide the desired force for effectively and rigidly holding the leg in extended position.

'I prefer to provide relatively deep notches 37 so that there is no danger of accidental releasing and folding of the leg while the notch 40 may be relatively shallow, so that it is not necessary to disengage the pin 28 from strengthening the same, the reinforcing being apertured and slotted to receive the pins and 28 substantiall as shown in Fig. 3.

I am aware that c anges may be made in the form, construction and arrangement of parts without departing -from the spirit of the invention, the scope of Which'should therefore be determined byreference to the following claims, which should be construed as broadly as possible, consistent with the state of the art.

I claim as my invention:

1. In a folding table of the class described, the combination of a table top, a bracket connected to said top, and having a pair of substantially parallel spaced arms, a hollow leg member having its upper end portion dis'- posed between said arms, a pivot pin extending through said arms and through the leg portion disposed therebetween, said leg being thereby pivotally mounted in said bracket member, a locking member extending through said leg and slidable lengthwise thereof and having its outer end portions adapted to interlock with portions of said bracket arms so as to maintain the leg in extended position, a compression spring for yieldingly urging said locking member into said interlocking engagement, and means vf or mounting said compression spring within said leg compris- -ing a tubular member pivotally mounted on said pivot pin and extending downwardly within the leg, said tubular member having its lower end closed for receiving and positioning the lower end of the spring,the upper end of said spring being disposed against a portion of said locking( member within the le the combination of a table top, a bracket connected to said top and having a pair of sub- 2. In a folding table of the class described,
