'7 Claims. 1 The present invention relates to furniture constructions, and, more particularly, to supporting leg structures thereof and means for mounting the same to the bodies of such constructions, such as chairs, couches, tables, etc.

. The general object of the present invention is to provide such constructions featured by leg units, each consisting of an arched member forming two spaced leg element adapted readily to be securely fastened to a furniture body in a simple and ready manner for emcient support of the latter with practice of minimum factory procedure requiring little skill and expenditure of relatively few man hours.

A more specific object of the present invention is to provide in such constructions leg units, each of which includes a pair of spaced-apart leg elements provided with a laterally mounted or anchoring flange so associated with other fastening means as to permit. ready securement to furniture body structure in an unusual and simple manner.

Another object of the present invention is to provide such furniture constructions which permit effective practice of the cold molding process of making articles from plastic materials, although it will be understood that the utilization of the structural features of the present invention is not limited to constructions formed exclusively from such materials.

A further object of the present invention is the provision of structural embodiments of articles of furniture featuring the present invention which are readily constructed and permit ellicient use thereof.

Gther objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements embodiment of the present invention shown in .an inverted position as would be normal in the assembly of the parts thereof;

Fig. 2 is a side elevational View, to a smaller scale, of the structure shown in Fig. 1;

Fig. 3 is an enlarged detail, with parts broken away, of anchoring means employed in the embodiment of Figs. 1 and 2;

Fig. 4 is an enlarged transverse sectional View taken substantially on line 4-4 of Fig. 2, with parts broken away;-

Fig. 5 is a sectional view taken substantially on line 5-5 of Fig. 4., with parts broken away;

Fig. 6 is a View similar to Fig. 5 of a modified form of the chair embodiment shown in Figs. 1 to 5 inclusive;

Fig. 7 is a sectional View similar to Fig. 4 of the modified construction shown in Fig. 6;.and

Fig. 8 is an exploded perspective View of leg and anchoring element structure of the construction shown in Figs. 6 and 7 Referrin to the drawings, like numerals identify similar parts throughout, and, as will be seen from the chair construction shown by way of example in Figs. 1 to 5, inclusive, the body of that piece of furniture may comprise a one-piece seat and back it preferably compression molded from suitable plastic material. The body unit it) preferably comprises a seat portion H and a back portion i2, with the margins thereof provided with integral strengthening flanges, such as the downwardly extending front flange I3 and side flanges M, M, which merge with the rearwardly extending strengthening flanges l5, I5

and H5 of the back portion. Each of the side flanges M is preferably provided with a pair of holes l1, H to receive fastening means, such as bolts i8, is adapted to receive on the inner ends thereof taps i9, 59.

The four legs of the chair construction shown in Figs. 1 to 5 inclusive are, in accordance with the present invention, provided by a pair of leg units 20, 20, preferably also compression molded from plastic material in the form of molded sheet structure of substantially uniform thickness, as is the body unit l0, for reason familiar to those skilled in the art of such moldingtechnique.

Each of the arched leg units 20 includes two spaced-apart leg elements 2!, 2| extending down away from opposite ends of a transversely extending mid-section 22 when that leg unit is oriented to its normal supporting position as shown in Fig. 2, or may be seen with an inversion of Fig. 1. Leg unit 20 includes side strengthening flanges consisting of a bottom'strengthening flange 23 and a top strengthening flange 24 extending laterally from the edges of the leg elements 2!, 2| and the mid-section 22. As is most clearly indicated in Fig. 1, the top strengthening flange 24 is elongated opposite the top edge of the mid-section 22 to provide an anchoring flange 25 having a terminal portion 26, with that laterally extending flange preferably provided with a pair of strengthening ribs 22, 2'! formed during the molding of the leg unit.

Each leg unit 20 is provided preferably in its mid-section, with a pair of holes 28, 28 adapted to be aligned with holes I1, I! in the side flange M of the body II! for reception therethrough of bolts I8, l8 to permit secure fastening together, as is indicated on the far side of the construction shown in Fig. 1. The mounting of each leg unit 29 to the underside of the seat portion II of the furniture body It is completed by securely anchoring the anchoring flange 25 thereto. In the form shown in Figs. 1 to inclusive, this may be accomplished by means of a stud bolt 22 riveted or staked in an anchor plate 30 molded Within boss 31, as best shown in Fig. 4. This anchoring means also includes a strap member in the form of a bowed clamping plate 32, centrally apertured at 33 to receive stud bolt 29, with its ends 34, 34 respectively adapted to lap over beneath the end portions 26, 26 of anchoring flanges 25, 25. The stud bolt receives a washer 35 and a tap 3B beyond or below clamping plate 32'to tighten and hold the parts together.

Itwill readily be seen in Figs. 1 to 5 inclusive that the chair embodiment shown therein consists of three major units, namely, two leg units as, 20 and body unit It. three units is readily accomplished by locating each ofthe leg units 20 beneath the seat unit II in a position similar to that indicated on the farside of Fig. 1, with the anchoring flange 25 thereof abutted against the under surface of the seat portion, and with the holes 23, 28 aligned with the holes 17, I1. Bolts I8, I8 are placed through those aligned holes and the taps I9, I9 threaded thereon and tightened to fasten each leg unit to the body unit. Each anchoring flange 25 is then securely anchored or clamped to the bottom of the seat portion II by placing the clamping plate 32 over the bolt 29 in the position indicated in Figs. 3 and 4, with the ends 34, 34 of the clamping plate lapping over the end portions 26, 26 of the anchoring flanges 25, 25. Washer 35 is placed. over the extending end of the anchoring bolt 29 and the tap 3B threaded thereon and tightened up so that the clamping plate 32 securely snugs the anchoring flanges 25, 25 to the underside of the seat portion II. It will thus be seen that very simple means are employed to assemble and secure the parts of the construction together, and that the anchoring fianges'of the leg units also provide loadbearing members on which the furniture body is efliciently supported.

In Figs. 6, 7 and 8 a modified form of the invention as employed in chair constructions is shown, and as there indicated, leg unit I20 may have anchoring flange I25 modified slightly both with respect to mergence with strengthening side flange I24 and strengthening rib structure I21. Further, such anchoring flanges I25, I25 may be extended so that the edges of their terminal portions I26, I26 will substantially abut at 31 when each leg unit I20 is positioned beneath the bottom portion II with its mid portion 22 fastened to the inner face of the downwardly extending seat flange I4 by the pair of bolts I8, I8 and taps I9, I9, as shown in Fig. 7. Anchoring'strap member I32 is shaped to have face engagement with the underside of the terminal portions I26, I26 of the anchoring flangesl25,

I25 and may havea rib 221 formed therein within which; portionsyof strengthening ribs I21, I21 I Assembly of those 9 of the anchoring flanges may nest. The anchoring strap member I32 is lapped over both anchoring flange terminal portions I26, I26 and is preferably anchored thereto in any suitable manner, such as by a layer 38 ofadhesive or cement.

It will be understood that since the leg units I22, I26 are fastened to the body I0 by bolts IS--I3 and taps I9I9 and their anchoring flanges I25, I25 are located beneath the seat portion II, any load imposed on the latter is efficiently supported by the leg units, with the anchoring flanges I25, I25 connected together by a strap member I32. However, it is preferred that the anchoring flanges I25, I25 be further fixedly connected to the seat portion II by any suitable supplemental anchoring means, preferably layers of adhesive or cement interposed between the top surfaces of the anchoring flanges and the bottom surface of the seat portion.

It will be ,readily understood that the assembly procedure for the embodiment of Figs. 6, 7 and 8 is comparable, as to simplicity and rapidity, with that involved for setting up the embodiment of Figs. 1 to 5 inclusive, and that the unique features of the present invention characterize both embodiments disclosed by way of example in the drawings. It will also be apparent that those constructions are well adapted to commercial mass production of pieces of furniture wherein the three major units are desirably formed by cold molding plastic materials. and that the resultant constructions are sturdy and efficient as to load-bearing characteristics, as well as contributing to the production of ornamental and pleasing designs.

It will thus be seen that the objects set forth above among those made apparent from the preceding description are efficiently attained and, since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
