2 Claims.

pact and out of the way positionand that can not. fold accidentally as long as it is supporting a table or piece of furniture.

Other objects are to provide a leg mounting means of this nature which is very simple in construction and very inexpensive to manufacture and which is especially well adapted for use on small tables, such as folding card tables.

While this invention is herein disclosed as being incorporated in a table, it will be understood that the same may be used in connection with other .pieces of furniture and with articles other than furniture on which the legs are to be folded.

Other and more specific objects of the invention will be apparent from the following description taken in connection with the accompanying drawing.

In the drawing:

Fig. 1 is a view in side elevation on a reduced scale of a table having legs provided with mounting means constructed in accordance with this invention, the legs being in extended position.

Fig. 2 is a side elevation of the table with the legs folded.

Fig. 3 is a fragmentary plan view taken substantially on broken line 3-3 of Fig. 1, and showing, on a larger scale than Fig. 1, one corner portion of the table and the folding leg therefor, as the same would appear with the table top removed. 7

Fig. 4 is a fragmentary side elevation on broken line 44 of Fig. 3.

Fig. 5 is a fragmentary sectional view, with parts in elevation, on broken line 55 of Fig. 3.

Fig. 6 is a detached exploded perspective view of the metal plates embodied in the invention.

Fig. '7 is a fragmentary perspective view of the upper end portion of one of the legs.

Referring to the drawing, l0 designates a table top having four reinforcing and supporting members ll secured to the bottom side thereof in rectangular formation and positioned a short distance inwardly from the respective sides of the table top. These supports ll do not intersect at the corners but terminate just short of the position where they would intersect, as best shown in Fig. 3, to leave open corner spaces for the reception of table legs l2. As the table leg mountings at all four corners of the table are identical only one of the same is described in detail. 7

Each two adjacent ends of the supports H are connected with each other by a right angle .cor-

ner bracket l3 which is applied to the outer sides of these supports H and secured thereto by bolts M, preferably having flat heads positioned outermost and nuts positioned at the inner sides of the supports H. In some instances rivets will be used instead of the bolts M. The corner forming portion of the bracket l3 has portions it of substantially the transverse width of the table leg which extend vertically below the plane of the bottom edge of the remainder of said bracket and serve as leg brace means. A j vertical slot is is provided in one part of the corner bracket I3 near the corner thereof, said slot l5 extending from near the top edge of the corner bracket l3 down into the legbrace portion l5 and connecting at its lower end with'an angle slot 19 which extends inwardly and is inclined downwardly at greater than a right angle relative to the slot 16.

A leg holding plate comprising a portion "3 adapted to engage with and rest against a support l l andan offset portion l9 and a longer leg engaging portion 20 is positioned against the inner side of one of the table top supports II and is secured thereto by the same bolts Mwhich secure the corner forming bracket I3 to said support. This leg holding plate I8 is positioned opposite the portion of the corner forming bracket l3 which has the slot [6-H therein and said leg holding plate is provided with a slot 2l-Z2 .of the same shape as the slot Iii-ll and positioned directly opposite said slot l6l'l. A notch 23 is providedin the bottom edge of the table leg engaging portion 20, as shown in Figs. 5 and 6. Preferably a flat plate 24 is provided in engagement with the inner side of the support I! opposite the non-slotted side of the corner forming bracket l3 and some of the bolts I4 pass through bracket l3, support ll and this plate M.

The upper end of the table leg I2 has one corner thereof removed to provide the rounded por- I tion 24 which gives clearance to allow the leg to be angularly moved between a position at right angles to the table top and a position parallel to the table top. Each leg member I2 is provided near the upper end with two

screws

25 and 26 positioned in alignment with each other and ex- F tending through the slots lB-I'l and 202| respectively and entering the'leg from opposite sides. Obviously a single pin extending through the leg and through the slots l$ll and 2ll2l all) may be provided instead of the

screws

25 and 26. The end portion of the support ll adjacent the inner screw 26 may have a relieved portion 29 to provide clearance for the head of the screw. A pin 2'! is also rigidly connected with the leg 12 and is positioned so that it is adapted to rest within the notch 23 when the leg is in extended position to provide additional brace means for the leg.

The upper end of the table leg l2 fits snugly into the receptacle provided between the right angle corner bracket 13 and the inside plate member I8l920 and the portions l and 20 extend downwardly far enough so that said leg is very firmly braced and provides a very strong and substantial leg means without using any diagonal brace means of the type sometimes employed. The only side on which the table leg, when extended, is not braced and supported below the plane of the table top supports H, by the metal corner members and 2D is the in ner side in the direction in which the leg folds and this side must be kept open to allow the leg to fold. The table leg, when extended, is securely braced against angular movement toward this open side by" the pin 21 which is always positioned in the notch 23 in plate portion when the table leg is in extended or set up position. A fiat spring 28 is secured to each table leg l2 to frictionally engage with a portion of one of the metal plates. The

screws

25 and 25, being positioned in the slots l6 and 2| help to brace and support the table leg 52 but their main function is to provide pivot means slidable in the slots l6-l'| and 2l22 on which the table legs may be pivotally moved and by which detachment of the table legs from thetable will be prevented. It will be noted that *the angular portions l1 and 22 or" these slots are not at right angles to the upright slot portions I6 and 2| but that their incline is in excess of a right angle. This incline has been found to be important in helping to provide smooth and easy action of the legs when folding. The incline of these slot portions l1 and 22 prevents the screws 25 and. 26 from binding in these slots and the rounded portion 24 from binding against the corner forming bracket l3 as I have found they will do if slot portions I! and 22 are at right angles to slots l6 and 2!.

The spring 28 provides enough friction to prevent the legs from dropping down out of their proper sockets in the event the table is lifted up while the legs are extended but the legs may be easily pulled out or pushed into their sockets.

When the legs are folded they lie parallel with and against the supports H, as shown in Fig. 2, and said legs are preferably retained in their folded position by frictional engagement of the ends of the legs with the outer side of the plate portions 2% of the legs at the opposite corners of the table. I have shown a glider member 30 on the bottom end of each table leg and have shown a pad 3! of friction material, as rubber,

- on each plate part 20 for the glider member 30 to engage with. If desired the glider members may be made of rubber and the pads 3! dispensed with.

The foregoing description and accompanying drawing clearly show a preferred embodiment of my invention but it will be understood that this disclosure is merely illustrative and that such changes may be made which are within the scope and spirit of the following claims.

I claim:

1. In leg mounting means of the class described, a member to be supported; supports secured to said member in rectangular formation with their adjacent ends spaced apart to leave a receptacle between said ends; a table leg having an upper end portion thereof positioned in said receptacle between adjacent ends of said supports when said table leg is extended, the upper end of said table leg having one outer corner thereof rounded off; to provide clearance for said leg when the same is angularly moved; a corner forming bracket of right angle shape positioned against the outer sides of two adjacent supports and having a portion positioned alongside of the table leg and extending below the plane of the bottom edges of the supports; a leg supporting plate positioned against the inner side of one of the supports opposite one portion of said corner forming bracket; means securing said corner forming bracket and said leg supporting plate to the support against which they are positioned; correspondingly positioned substantially upright L shaped slots in said leg supporting plate and in a parallel portion of said corner forming bracket; and aligned pins in said leg operatively disposed in said slots permitting said leg to be moved longitudinally between said plate and said bracket and to be folded parallel to the adjacent support.

2-. In leg mounting means of the class described,
