This invention relates to sway chairs or the like.

One object of the invention is to provide a chair, couch or the like, embodying among other characteristics, a supporting frame and a cushion frame flexibly mounted on the supporting frame for a floating movement in all directions, and within certain limits, with a tendency of the cushion frame to normally center itself with re lation to the supporting frame.

Another object of the invention resides in the provision of an underslung chair, couch or the like having its seat portion flexibly connected to its base in such a manner as to permit of floating movement of the seat portion in all directions and to prevent undue shocks to the seat portion as it floats into and out of normal position with relation to the supporting frame.

Another object of the invention is to provide a chair, couch or the like, embodying a supporting frame and a cushion frame overhanging the supporting frame with the ends of the supporting frame arranged inwardly of the ends of the cushion frame and flexibly connected to the supporting frame for floating movement thereof within certain limits and to such an extent as to overcome noises incident to jarring of metal parts of one frame against the other.

A still further object of the invention is to provide a substantial, durable and comparatively inexpensive structure of the nature stated and constructed in a manner which will permit ready assembling and disassembling of the parts so that when desired the structure may be readily taken apart or collapsed so as to economize space when it is desired to store the device, as for instance, during times of the year when the chair, couch or the like is not in service.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement or" parts hereinafter fully described, illustrated in the accompanying drawing, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawing:

Figure 1 is a perspective View of the invention illustrating cushioning means in part but which cushioning means forms no part of the present invention.

Figure 2 is a perspective view of the invention with all upholstering or seat or back cushioning means removed.

Figure 3 is a transverse sectional view on the line 33 of Figure 2, a part of the respective brackets and the respective arm rest being broken away.

Referring now more particularly to the accompanying drawing, the reference character 1 indicates wood or other suitable bars each of which may be provided with the spaced feet 2 upon which may be mounted a suitable metal or other type of supporting frame.

The supporting frame illustrated in the drawing consists of two longitudinally disposed spaced front and

rear angle irons

3 and 4, respectively, which may be bolted or otherwise secured to the aforesaid transverse bars 1 with their ends projecting slightly beyond said bars 1 and connected intermediate their ends by one or more connecting links 5.

End pieces are detachably secured to the opposite ends of the

longitudinal angle irons

3 and 4. These end pieces each consist of a pair of uprights 6 of angle iron, detachably bolted at 7 to the respective ends of the

longitudinal angle irons

3 and 4, the upper ends of each pair of uprights 6 of the end pieces being connected by a cross piece 8 of angle iron, which may be riveted or otherwise secured at 10 to the upper ends of said uprights 6 and braced by the braces 11, riveted or otherwise secured at their ends to the respective cross pieces 8 and uprights 6, as shown. The fastenings '7 are preferably in the nature of screw bolts, so that for knock-down purposes the fastenings 7 may be loosened to permit the end pieces to be swung down onto the front and

rear bars

3 and 4. To prevent any possibility of accidental folding of the end pieces onto the

bars

3 and 4, links 12 are provided at each end of th supporting frame, and these links may be connected at their ends by screw bolts 13 to the uprights 6 and the

respective bars

3 and 4, so that by removing the screw bolts 13 from operative connection with the links 12 at either end thereof, the end pieces may be folded down onto the

bars

3 and 4 when desired.

The cross piece 8 of each end piece of the supporting frame projects beyond the uprights 6, and as shown, these ends are preferably deflected upwardly, forming front and

rear arms

14 and 15, respectively, for each end piece, and each arm adjacent its outer end is preferably provided with an eye 16 for a purpose presently explained.

A cushion supporting frame is disposed over the supporting frame in such a manner as to provide for an underslung mounting of the cushion frame. This cushion frame may be composed of longitudinally disposed front and

rear angle irons

17 and 18, respectively, connected at their opposite ends by cross pieces 19 in the form of angle irons. These cross pieces 19 of the cushion frame may be riveted, bolted or otherwise secured to the angle irons 1'7 and 18. As shown, the

angle irons

17 and 18 have their vertical flanges directed upwardly and their other flanges directed inwardly horizontally toward each other for the purpose of receiving and supporting a spring structure (not shown) against lateral displacement, but as the matter of spring mattress or cushions mounted thereon or directly upon the

bars

17 and 18 is not the essential part of the present invention, it has been deemed unnecessary to illustrate the same. In any event, the front and

rear angle irons

17 and 18 are preferably connected by downwardly curved or bowed bars 20 for strengthening purposes and which may have their ends secured to the respective bars by means of rivets or other suitable means 21, the bowed formation of the connecting braces 20 permitting depression of a spring mattress or structure or other cushioning means without discomfort to a person seated upon the chair, couch or the like. Bracing elements 22 at the corners of the frame formed by the longitudinal angle irons 17-18 and the cross pieces 19 may be employed, if desired, and riveted or otherwise secured at their ends to the bars and cross pieces, as shown particularly in Figure 2.

A pair of suitable brackets are secured to the

angle irons

17 and 18 of the cushion frame, one pair at each end of the cushion frame and each preferably formed alike. As shown, these brackets are each V-shaped in formation, including leg portions 23, a bight portion 24 and feet portions 25, which latter are riveted or otherwise secured against the under face of the horizontal portions of the respective front and

rear angle irons

17 and 18. The brackets are so positioned on the cushion frame as to straddle the

aforesaid arms

14 and 15 of the end pieces of the supporting frame with the arms of the end pieces of the supporting frame preferably projecting between the legs 23 of said brackets, substantially centrally thereof and at the upper ends of the same. A chain or other flexible connection 26 has its upper link detachably hooked into the eye 16 of the

respective arms

14 and 15 with its lower end detachably hooked in an eye 27 located at the bight portion 24 of the respective bracket and between the legs 23 of the bracket. These flexible connections 26 are all preferably of the same length and they normally lie in a vertical position between the brackets and parallel with the legs 23 of the brackets, as shown particularly in Figure 3.

By virtue of these flexible connections 26 between the arms 14-15 and the said brackets of the cushion frame, the cushion frame has an underslung mounting and is permitted a universal or floating movement on the supporting frame, within certain limits, and in such a manner that the tendency always is for the cushion frame to assume its centering relation with the supporting frame, with or without weight on the supporting frame. The movement of the supporting frame in various directions is limited by the length of the flexible connections which have movement out of their vertical positions to an extent substantially within the distance between the diverging legs of the brackets, with the result that the floating movement of the supporting frame is such that when the cushion frame swings longitudinally of the supporting frame the braces 28 between the outer legs of each pair of brackets do not contact with the upright 6 of the end pieces of the supporting frame, thereby obviating unnecessary noises. The brackets referred to provide not only means for mounting the cushion frame but their particular shape serves as a bracing means for the cushion frame structure, as is manifest by the disclosure of the drawing. In other words, the V shaped brackets perform the dual function of strengthening the cushion frame and also providing hangers or brackets for the underslung mounting of the cushion frame on the supporting frame.

Arm rests, which may be composed of angle iron or of any other suitable material and which may be of any desired form or shape, are mounted on the ends of the cushion frame. As shown, the arm rests 29 may be riveted or otherwise secured to the upper ends of the arm rest uprights 30, as at 31, and these uprights 30 may be secured to the respective ends of the front and

rear angle irons

17 and 18 by means of suitable screw bolts 31, which may be loosened and removed when desired, so as to detach the arm rests from the structure for storage purposes. The rear uprights 30 are provided with seats 32 for the support of any suitable back 26 and this back 26 may be supported against backward movement by means of suitable lugs 33 provided with eyes 34 for the reception of suitable fastenings (not shown) whereby to secure the upholstered back 26 to the arm rests. As shown in Figure 1, cloth or other suitable material 35 may be stretched across the cushion frame to provide a support for an upholstered or other cushion 36, as shown in Figure 1, and if desired, the cushion 36 may be provided with a skirt or apron 37 of any suitable character to conceal the structure under the cushion frame. As hereinbefore stated, the cushioning means for the cushion support may be of any suitable character and it may be of such nature as to fit down within the front and

rear angle irons

17 and 18 of the cushion frame and rest on the horizontal flanges of the

angle irons

17 and 18 and held against forward or rearward lateral movement off of the cushion frame by the vertical flanges of the

angle irons

17 and 18, longitudinal movement of such cushioning structure being prevented by the inwardly directed flanges of the angle iron uprights 30 of the arm rests, as will be well understood.

From the foregoing it will be seen that I provide an underslung seat having a four point flexible mounting and thereby providing for a floating movement of the cushion frame in all directions, substantially horizontally with relation to the supporting frame. It will also be seen that by virtue of the two metallic frames, illustrated, one flexibly mounted upon the other in the manner specified, that I provide for substantially an even floating movement of the cushion frame and in such a manner is the mounting arranged that there is always a normal tendency for the cushion frame to center itself with relation to the supporting frame, with or without weight on the cushion frame. It will also be seen that the end pieces of the supporting frame are confined within the ends of the cushion frame, as distinguished from a structure wherein the end pieces of a supporting frame might be located beyond the ends of the cushion frame and its arm rests.

It will also be understood that by virtue of the V shaped hangers or brackets that there is sufficient space or clearance within the upper portion of the hangers or brackets for the swinging movement of the chains or other like connections when the cushion frame sways longitudinally and that by reason of the downward converging of the legs of the V shaped hangers or brackets there is sufficient clearance between the latter and the supporting cross pieces 1 as will prevent contacting engagement between the cross pieces 1 and the hangers or brackets during a longitudinal swaying movement of the cushion frame While there may be a slight dipping movement of the cushion frame as it sways, it will be understood that the movement is substantially horizontal or substantially in the same horizontal plane at all times.

What is claimed is:

1. In combination in a sway chair or similar furniture construction, a supporting frame having at the upper end portions thereof forwardly and rearwardly transversely extending arms, and spaced from the ends at the lower portions thereof transversely extending supporting bars providing foot portions that extend forwardly and rearwardly from the main structure of the supporting frame, a cushion frame comprising transversely spaced longitudinally directed front and rear members, and transversely extending cross pieces located at the ends of and connecting the longitudinally directed front and rear members and having secured at each end portion of said longitudinally directed members a V-shaped bracket with the legs of each V arranged so that they lie in the same vertically and longitudinally extending plane, and from the outer ends of each of said arms that extends from the supporting frame a depending flexible connector the lower end of which is connected to the bight portion of the V-shaped member to which the arm and depending fiexible connector correspond, the outer end of each arm whereat the flexible connector is connected being located midway between the up per ends of the legs of the V-shaped bracket and substantially directly over the bight portion of the V-shaped bracket corresponding to the arm, the several flexible connectors being of substantially equal lengths, the lower ends of the V- shaped brackets being located so that they extend below the general elevation of the upper surface of the end foot portion of the supporting cross bar, the longitudinal movement of the cushion frame being controlled because of the length of the flexible connectors and the clearance allowed within the open portion of the V- shaped members so that the lower ends of the V-shaped members will not strike the transverse- 1y extending supporting bars that provide the outwardly projecting end foot portions.

2. A supporting base for a sway chair or similar furniture comprising relatively closely spaced longitudinal members, transversely extending bars connected to said members within the ends of the latter and extending beyond the sides thereof, pairs of relatively short uprights connected to said longitudinal members at the ends thereof, a transverse member connected to the upper end of each pair of uprights and each of the latter members having upwardly inclined arms at the ends thereof, brace connections between the longitudinal members and said uprights, and brace connections between said uprights and the members which connect the upper ends of the uprights, the outer ends of the arms having perforations therein:
