14 claims. (ci. 15s-179) This invention relates to articles of seating furniture Vsuch as chairs, benches, settees, sofas, couches and vseated, outer or surrounding supporting frame with legs for supporting it above the floor, and a flat and resilient, cushion-supporting insert that fits removably snuglyV into the top opening encircled by the supporting frame, and a resilient seat cushion carried on the cushion-supporting insert. This insert itself constitutes an important vsubcombination of the invention and is ilushwith the top of the surrounding supporting frame when inserted in it.

The outer or surrounding supporting frame can have any horizontal shape that is used in any seating article of furniture that has a seating cushion carried on a spring base. Legs depend from suitable positions on the supporting frame to hold it with its seating plane in a generally horizontal relationship spaced above a floor surface. The expression generally horizontal relationship embraces both the true horizontal position parallel to the floor as well as that where the seat has a downward incline from the front to the rear.

Advantageously, theinnerportion of the top surface or face of the surrounding frame is depressed to provide a top inner annular shoulder to serve to receive in supporting yet removable engagement an annular flange eX- tending horizontally outwardly `along the top of the cushion-supporting insert. That shoulder is best depressed merely for such kdepth sutiicient to hold the insert with its cushion-supporting surface flush with the nondepressed portion of the top face of the surrounding frame.

The resilient, cushion-supporting insert of the invention thus is constructed with its frame, conveniently called the insert frame, of such peripheral contour that parallels or is the same as that of the top inner peripheral contour of the surrounding frame, and of a `size to tit removably in snug contact with the inner contour of it and present a top flush surface with it as just above described. A strengthening rib or web depends from the under-side of the insert frame and is spaced inwardly from the outer peripheral edge of the flat top of the insert `frame to provide the above mentioned horizontally outwardly extending annular flange.

A plurality of flexible flat bands, preferably ofa metal `that is not frangible on being flexed, are tautly stretched in parallel and horizontally spaced apart relationshipv between opposed positions in the top of the insert frame and each is anchored at each of its ends to the frame by 2 I, an interposed helical coil having one end inserted in an aperture in the llat band and the other in an -aperturein the insert frame. The carrying strength and `resilient atness of the insert frame is greatly increased by a second plurality of such flexible ilatbands similarly tautly stretched in parallel and spaced apart relationship but transverse to the first plurality ofu bands, and advantageously interwoven with them, and similarly anchored to the insert frame. A

It is beneficially effective for the depending strengthening rib to be spaced inwardly also from the inner peripheral edge of the ilat top of the insert frame to provide a horizontally inwardly extending annular flange and that there be located in it the apertures in the insert frame that serve as its anchoring points for the helical coils of the llexible flat bands. Accordingly, the insert frame advantageously is constructed withY a T cross section."y

As will be recognized more fully from the later'description, various novel constructional features of the invention, such as the use and structure of the cushionsupporting insert with its outwardly extending annular flange carried on the surrounding frame, and the resulting efficient weight load distribution, especially'enhanced by the depending strengthening web,y permit the surrounding frame to be of substantiallyless strength than was heretofore required before the use of this insert.` This then allows the use of relatively slender proportions in the outer surrounding frame to present not onlya pleasing lightness in appearance but also significant savings in materials. These structural features, by also permitting the elimination of the earlier used vertical coil springs as part of the support for the seat-cushion, additionally contribute to the relatively slender proportions and lightness in material weight and appearance of the surrounding supporting frame. f

Then too, the inclusion ofthe `,cushion-supporting insert allows a greater flexibility as to the locations at which the supporting legs need be affixed to the supporting frame. In general, the selection ofl such locations can be independent of structural support specifically fof the supporting frame, other than to avoid toppling ofthe seating furniture article, and thus is related merely to the `nature of the distribution of the seating load that will be placed on it. Thus, location of legs within strategic zones under the cushion-supporting insert takes advantage of the signicant strengthening and reinforcement it contributes to the supporting frame and enables use of a minimum number of legs. Thus, even merely four legs, that' is, a front pair and a rear pair, are sucient even for a settee of possibly greater than usual width. Moreover, the legs in each pair may be spaced relatively far apart with a substantial length of span of directly unsupported surrounding frame in spite ofy its light construction. ln addition, in either chair or settee or other type of seating furniture, the legs canfbe affixed `to the supporting frame a reasonable distance inwardly from its corners, leavingan outwardly extending cantilever portion, so long as the latter is not so long as to permit upsetting of the furniture article whenthe cantilever portion is loaded.

A resilient seat cushion is supported on 'theA cushionsupporting insert. Then also, certain forms of the seating furniture article of the invention have `a back Vrest `extending upwardly from a rear portion of the seat, and against which can be supported a back cushion. One chair form of the invention has arm rests, on opposite sides of and spaced above the seat frame, having their forward ends xedly connected to the seat surrounding frame, for example, by being directly connected through upward extensions of the front legs. Thenthe rear ends of the arm rests are joined by a connectingor back-sup- 3 porting memberV extending transversely across, and abutting against, the back of the back frame.

This particular construction diverts a significant portion of the load placed against the back frame to the backsupporting member, and fromvl it to be divided and in' turn transmitted through theV arm' rests and the upward extensions of the front legs'. to that forward portion of the seat 'surrounding frame. Such diversion of back frame load to elsewhere in the chair' permits lighter construction 'in th'e'bae'k frame and corresponding materialVv savings and greater latitude in styling'.

They invention` is explained in? greater detail in relation to specific embodiments shown for illustration only, and notN to 'be limited thereto, inthe accompanying drawings wherein:

` In the drawings, the chair, generally designated 20, includes an outer surrounding supporting frame 21 which is preferably rectangular or may be of other polygonal or rounded configuration, and its pair of depending front legs 22v and pair of depending rear legs 23 to maintain the seat frame in a generally horizontal relationship to the floor. The outer frame 21 preferably has its upper surface depressed, as at 24 (Fig. 4) yalong its inner marginal portion to define a peripherally extending shoulder, for a purpose more fully described below. The' front legs may be secured to opposite sides of the outer surrounding frame at points spaced backwardly from the front of it (Figs. '1'. 2 and 3):

The back' frame 2S, extending upwardly from Vthe rear of the surrounding' frame 21, can also be substantially rectangular in configuration, and preferably includes vertic'al"s't`rut's 26'; Arm rests 27 are arranged on opposite sides of the 'surrounding frame 2.1 and. 'spaced above it 'at' a relatively yhorizontal level intermediate the upper and lower'ends of back `frarne 25. The forwardl end of each arm rest 27 is`fixe'dly connected with the forward portion oflthes'ur'rounding frame 21 by a connecting member 28 whichl advantageously-can be an upward Vextensionof its respective front leg 22. The rear ends of the `arm rests 27 beneficially are connected together by a connecting or back-supportingmember' 29 whi'ch'is positioned in back of and in transversely abutting engagement with back frame 25 and its vertical struts 26, at a horizontalI levellintermediate their height, for reasons which are developed below.

v The'surrou'ridin'g frame, back frame, armrests, and legs, being exposed in the finished article of furniture, generally are fabricated of wood or other desired ornamentalA niaferial.y The frame parts have relatively low strength re- 4. quirements and thereby can be made of light Weight materials and are prone to versatility of st-yling.

The cushion-supporting insert 30 includes its frame 31 which is preferably rectangular or may be of other polygonal or rounded `configuration so long as its outer peripheral contour is the same as the top inner peripheral contour of shoulder 24 of surrounding frame 21 and of a size to fit removably in snug cnt'act with that shoulder and present a relatively flush surface with the top of frame 21. Thus, in the assembled chair, cushion-supporting insert 30 is carried removably'disposedv in frame 21.

Frame 31 of insert 30 is constructed advantageously of bar stock, T-shaped in section, and preferably of a single length of such material, preferably steel, equal to the frame circumference. This is done by cutting from the flange of the T-shaped bar stock, at each of three locations spaced apart from the ends and from one another respective individual distances corresponding to the respective length of each of the frame sides, a pair of opposed and wedge-shaped notches each extending inwardly from an opposite side of the flange andv terminating adjacent to the depending wall or web; and then bending the stock inwardly at each pair of notches to form the rectangular configuration. It is beneficial to mitre the ends of the bar stock, and then weld the mitred ends and the meeting edges of the notches to provide a relatively rigid inner frame structure.

From Fig. 6, it is seen that the above mentioned cuts or notches serve to permit .bending of the depending portion or web 34 without deformation of the inner and outer flange portions 35 and 36; and the notches in the outer flange portion define beveled corners, as at 37, after the bending, to afford convenience in removing the insert from the supporting frame 21 and safety in handling.

Spaced apart from one another along the inner flange portion 35 of insert frame 31 are a plurality of through apertures 38, each of which is adapted to receive one end of a coil spring 33. A plurality of flexible strips or bands 32, preferably of spring steel, are tautly stretched in parallel and spaced apart relationship between opposite sides of insert frame 31, and each such band is anchored at each of its ends to its respective side of frame 31 by an interposed helical or tension spring 33 having one of its ends inserted in an aperture 38 in flange portion 35 of frame 31 and the other in an aperture 39 in the end of the respective band 32. A second plurality of such flexible bands 32 is similarly tautly stretched between the other two opposite sides of insert frame 31 transversely to the first plurality of bands and interwoven with them and similarly anchored to insert frame 31.

As best seen in Fig. 2, and considering Figs. 5 and 4 as if in exploded view relationship to one another, the cushion-supporting insert 30 rests within the outer surrounding frame 21, with' the outer flange portion 36 of insert frame 31 seated over the shoulder, or within the depressed portion, 24 of outer frame 2l. Thus, as seen inV Fig. 1, all sides of insert 30 are similarly supported in outer support frame' 21. Iny addition, the depenling web or rib 34 of insert 30 extends into and advantageously engages with the inner periphery of outer frame 21, thereby serving positively to locate and maintain insert 30 in proper position with respect to outerv support frame 21.

While it is preferred to provide' outer support frame '21 with the' shoulder or recessed marginal portion 24, so that the insert 3'0 can be substantially flush or level with the outer supporting frame smoothly to support the seat cushion 41, it is appreciated that the depressed portion may be omitted, and thatthen web 34 will function to maintain insert 30 and outer'support frame 21 in their proper relation.

As the insert frame 31 extends along, and in engagement with, the outer support frame about the total circumference of the latter, and as the former preferably is fabricated of iron or Vother suitable metal, it is apparent l,web 34 also prevents twisting of that frame.

. g) that insert frame 31 serves substantially to reinforce outer support frame 21 and permit reduction in thickness and strength of the sides of the latter. In particular, web 34 serves to reinforce and strengthen both iianges 35 and 36 of the T-shaped section insert frame 31 and also the outer surrounding support frame 21, and will itself support normal seat loads. In addition to resisting bending of insert frame 31 under seating loads, depending That is, although downward deflection of the flexible band members 32 under seating loads might tend to twist the inner flange portion 35 downwardly, web 34, by its continuity from side to side and also engagement with outer frame 21 serves effectively to resist any such twisting force.

With the cushion-supporting insert 30 resting in the outer surrounding support frame 21, and the seat cushion 41 positioned on the cushion-support insert and the surrounding frame, it is only necessary to place the back cushion 4) on the seat cushion and against back frame 25 to complete the chair, as shown in Fig. 3.

Seat cushion 41 can be of any suitable resilient material and should be thick enough to mask the sitters being able to feel any part of the cushion-supporting structure through the cushion, while being seated on it. Advantageously, cushion 41 can be of rectangular prismatic forni for it thus presents a suitably level base stably to support the back cushion 40. Thus, a substantially rectangular prismatic block of foam rubber is particularly advantageous as the seat cushion 41. Such a block of that material is also especially beneficial as the back cushion 40.

Obviously, the various above-described separable chair parts may be independently constructed, transported and stored, to provide considerable savings in manufacture and distribution. Then too, interchangeability of parts is economically available to facilitate any necessary replacement. l

Figs. 741() show a settee, generally designated 50, which isconstructed in accordance with, and contains the advantageous structural features of, the invention. The settee includes a laterally elongate, preferably rectangular outer surrounding support frame 51 having front and rear lengths 52 and 53 respectively, and relatively wide side members 54. The front and rear lengths 52 and 53 of support frame 51 are provided along their inner edges with longitudinally extending recesses or recess portions 55 and 56 and a shoulder-providing strip or member 57 is secured in underlying relation with respect to each side member 54 to define with it a recessed shoulder 58. A

pair of front legs 59 depend from the front length 52 y Vto that of the outer frame, and a plurality of flexible strips or bands 63 tautly stretched between each pair of opposed sides across the insert frame and respectively interwoven and resiliently connected by their ends to their respective sides by helical tension springs 64, in the same manner as in the insert 30 of chair 20.

The cushion-supporting insert frame 62 can be constructed similarly to insert frame 31 of chair 20, but alternatively is advantageously of angle iron with its horizontal flange 66 extending into the interior of the rectangle and its vertical wall 65 depending from the outside edge of the horizontal flange. A single length of angle iron preferably is cut or notched at three locations on its horizontal flange and spaced apart from its ends and from one another by distances corresponding to the respective lengths of the frame sides. The angle iron CII 5 then is bent at each of the cuts, and its, meeting ends welded together, to form a rectangle.

Along the exterior of each side of the rectangle of angle iron is secured, by welding or other suitable securing means, an additional length of angle iron, which can be somewhat shorter than its respectively associated rectangle side, and arranged with the exterior of its vertical wall in face to face abutting engagement with the adjacent vertical wall of the respective rectangle side, and its outwardly extending horizontal liange substantially flush with the inwardly extending horizontal flange of the associated rectangle side.

Thus, as illustrated in Figs. 8-10, the angle iron 84, bent as above described to form a rectangle, includes its depending vertical wall 65 and inwardly extending horizontal flange 66. Extending exteriorly along each side of the rectangularly bent angle iron 84 is secured, intermediate and spaced from the ends of said sides, an angle iron 67 having its depending vertical wall 68 in facing engaging relation with the depending wall 65, and having its outwardly extending horizontal flange`69 substantially iiush with ange 66. Hence, as best seen in Fig. 9, angle iron 84 (with its horizontal flange 66 and depending wall 65) and angle iron 67 combine jointly to provide a frame of T-shaped cross section, wherein the depending web of the T-shaped section is of greatly increased strength by being composed of both depending vertical walls 65 and 68.

The inner horizontal flange 66 of the cushion-supporting insert frame 62 is provided with a plurality of spaced apart through apertures 70, each of which is adapted to receive respectively one end of a coil spring 64. Each of the opposite ends of the strips or bands 63 is provided with an aperture 71 for each such end to receive the other end of a coil spring 64. Thus, the interwoven flexible bands or strips 63 serve to provide a rm but resiliently yieldable support for a seat cushion 72 of the same type as cushion 41 of chair 20, and in the same manner as described in relation to that chair as shown in ,Figs 1-6.

When the cushion-supporting insert 61 is resting within the outer surrounding support frame 51, the outer flanges 69 are seated in the recesses 55 and 56, and on the shoulders 58; and the depending web (68 and 65 combined) of the insert frame 62 extends downwardly and engages with the inner faces of the front and rear lengths 52 and 53, respectively, of surrounding frame 51 and the inner face of each of the side strips 57. Hence, the rigidifying and strengthening coaction of cushion-supporting insert 61 and surrounding frame 51 relatively parallels that of the cushion-supporting insert 30 and supporting frame 21 in the chair 20. Then, since the reinforcing web of the cushion-supporting insert frame 62 is of increased strength, the span permissible between legs of each pair of legs is accordingly increased, a highly desirable feature in settee construction, especially with the legs positioned under the insert frame and inwards of its corners, as described above. Y

In addition to strengthening the web of the T-shaped section, the spring unit frame construction of Figs. 7-10 makes possible a significant savings in materials. That is, the lengths of the angle irons 67 may be less than that of their associated rectangle sides while still retaining the functional advantages of the T-shaped cross-sectional frame section.

As the spring unit frame 62 generally is of suflicient strength to carry the entire seating load,` the side to side span length between legs (from left to right) is not critical, and even an overly wide settee may be adequately firmly supported by merely four legs, especially when located as above described. Moreover, as seen in Figs. 8 and 9, the settee can be constructed with its sides overhanging the legs, and the spring unit frame will support effectively a seating load on the overhanging portion in the manner ofa cantilever beam.

M'lhe settee Sil-may bevcompleted by including arm rests 73 secured, for example, alongV the outer edges of the outer surrounding support frame side members 54', and a back' rest74 secured to the rear frame member 53 and connected between Athe arm rests. Arm or side cushions '7 5 can be disposed on the relatively wide side, support frame members` 54, and one or more backcushions "lo can be supported on the seat cushion 72 and against the back rest or frame 74. These sidey cushions and back cushions can be ofthe same type as the cushions of chair 20. Each such cushion can be inclosed in a suitable fabric envelope, of conforming shape andv sealed at each edge except one that would not be readily seen, which would serve as the mouth and be closable by suitable means such as a Zipper closure Wide versatility in dimensions and' design thereby is afforded' by the construction of the present invention, it being necessary only to locate the loaded center of gravity to prevent toppling or upsettingVV of the article of seating furniture. v
