This invention relates to improvements in cushions for furniture, such as sofas, loveseats, and lounge chairs.
Sofas, large lounge chairs, and other upholstered furniture have traditionally been cumbersome, heavy, and disposed to get dirty though they are not easy to clean. Typically, they have been availablein a limited number of upholstery fabrics, have been expensive, and reupholstery has also'been veryexpensive. The front edges of the arms of the sofa or chair have generally been exposed to the greatest traffic and so generally have become the first parts to wear. When they were" worn through, it has usually been necessary to reupholster the whole sofa or chair or to discard it. The present invention is directed to a solution of these problems.
Customarily, sofas, for example, have been designed in two ways. In one, the backs are higher than the arms and in the other the arms have been equal to the height of the backs. The latter approach, although employed advantages and is also applicable to high-back sofas.
A typical housewife desiring to purchase a sofa or lounge chair has heretofore gone to a furniture or department store and chosen the product from a small choice of upholstery fabrics, placed an order, and
waited for much later delivery to her home by a large.
truck. Occasionally, the store has had one on hand that pleased her, but even then she has had to wait for the delivery, which wasoften delayed and usually required the labor of two men. Once the. sofaor chair has been delivered, it was difficult for her and her-husband to move. it around. Also, after she had used it a while, it being to get dirty. The cushions-sometimes had removable covers so that cleaning of them was possible, but the actual upholstery on the body was generally tacked on and could only be properly cleaned by complete removal, for, while shampoo cleaning was possible on an installed sofa, it was usually difficult and unpleasant to do, and the product itself was, of course, not usable until the shampoo dried, which usually took several hours. Once wear occurred, reupholstery required the tedious job of removing the old fabric, then sewing and tacking on of new fabric.
The present invention is addressed to these problems and presents useful solutions. When furniture made by this invention is to be purchased and the housewife visits the furniture or department store, she can pick out the products, choose one or more of any of a very large number of available packaged upholstery fabrics and can carry the upholstery fabric and a compact package containing a partly disassembled sofa or chair out to her car by herself and take it home with her in an ordinary sized car. She may not even need help in carrying the package or liftingit into the car, although this help can be easily supplied by service personnel at the store. When she has the package at home, she is able to carry it into the house,- unwrap it, slip the removable upholstery on it, and assemble the chair or sofa together 2. withoutemploying tools; it is then ready for use. When it needs to be cleaned, the upholstery is readily removed and readily replaced.
One feature of the invention isits utilization of stretch fabrics in connection with zippers. Up to-now it has generally not been practical to incorporate zippers on stretch fabrics such as slip upholstery covers, since the use, ofthe zippers, which certainly do not stretch, defeats the purpose of'utilizingstretch fabrics, which are used only sothatthey can be'stretched wider than the object whilexputtingthem-on; When a zipper.
is placedin' its customary position along the opening, itopens and closes, but the'non-stretch tape on each side of the zipper prevents-the openingfrom stretching, and-this-isthe very point where an opening should be able to be widened-inorder touse the stretchable fabric. The present invention also overcomes this difficulty and' provides useful arrangements.
Manyother objects, features, and advantages of the invention williappear from, and many are explained in detail in', the followingdescriptionuof some preferred forms thereof.

The sofa shown in FIG. 1 is a typical example of a fully upholstered sofaembodying the present invention. It comprises a basic frame structure 101 supporting the upholstery and a series of seat'cushions members 102. The basic frame structure 101 comprises a pair ofside panel members 103 and 104 (FIGS. 3 and 4), which may be identical and serve as the legs" for the sofa 100; they comprise verticalsheet-like members of strong plywood or plastic or metal, all of sufficient thickness and strength to support the sofa and its load. Each side panel member 103, 104 has a vertical may be omitted. There is a front edge 108 and a rear edge 109.
comprise a single foldable sub-assembly. The back frame 110 may be folded over on top of the seat frame (FIG. 11) or; in a modified structure, may be folded beneath the seat frame by means of somewhat different hinges. When erected, the seat frame 110 is horizontal,
and the back frame 111 vertical, at substantially a right angle.
The seat frame 110 may have a rear bar 113, two side bars 114 and 115, and an up-raised front member 116; it may be constructed from wood with some metal reinforcements or attachments. The higher front member 116 adds to the comfort by inherently providing a down slop from the front to the rear and also helps hold the cushions 102 from sliding forward. One (or more) wood or metal stretcher member, preferably bowed, joins the front member 116 to the rear bar 113 in between the side bars 114 and 115 for sofas; for chairs no stretcher is needed.
Suitable cushion-supporting springs 118 may be provided. Other types of springs may be used instead of what is shown. While the springs may be of nearly any type, flat springs are preferably, because they make a compact package and their whole top surface is a supporting platform, whereas coil springs extend far below the top ring, so that the top ring is not a supporting surface, and webbing and wire insulators would be required to hide the feel of those springs. While arcuate springs also work well, the flat bar-like rubber springs 118 can be installed by staples and hence are often preferred. The stretcher helps to enable the frame 110 to withstand the tension which the installation of the springs 118 brings about.
The hinge connections between the seat frame 110 and the back frame or panel 111 also imparts an important strength feature. The thin rear seat frame beam or bar 113 could not alone carry the weight of a heavy person; it would only take the horizontal tension of the springs 118. However, in erected position, the hinges make the back structure into a right angle between the bar 113 and the back frame or panel 111. This imparts adequate strength to the bar 113 to carry the load of people. This novel combination provides the needed strength with a desirable lightness of weight and aids also in providing both of these with a folding structure, all cooperating in providing the take-home feature. If the bar 113 were to be hefty enough to be able to take by itself both the horizontal rear-to-front pull of the springs 118 and the vertically downward force of the people sitting, it would have to be very heavy, as are prior-art sofas. With the hinging, strength, light weight, and portability are all achieved.
The back frame 111 basically comprises a member shaped generally like the side panel members 103 and 104, though none ofit rests on the floor; there is an upright back portion 120 and there may be a horizontal top portion 121, which is normally level with the arms 107. There is a bottom edge 122, a rear edge 123, and two side edges 124 and 125.
The sofa 110 may, if desired, be used in a noncovered version in which the back 111, seat 110, and sides 103 and 104 are all made principally out of materials with a satisfactory surface for this purpose, such as a high quality wood or a suitable plastic or suitably decorated metal members, or a combination thereof. If
they are to be used in that form, they do not need to be provided with any fabric covering, but otherwise they are provided with fabric covering in accordance with this invention in a manner whichis described below.
FIG. 2 shows an upholstered lounge chair 132 and FIG. 3 shows a lounge chair 133 whose panels 103 and 104 and back frame 134 are not upholstered. Both of them are very much like the sofa except for the length of the seat frame and back frame, and both of them include the cushions 102. No stretcher 117 is required for the chair 132 or 133.
FIG. 12 illustrates a similar line of sofas and chairs having a high back instead of the low back of the sofa 100.
FIG. 12 shows a chair 139 with a high back structure, curved at its upper end, but with its frame unupholstered, though employing a cushion assembly 102. Obviously, love seats, four-seaters and many other variants are possible.
In all instances the side panels 103 and 104 are attached to the seat frame 110 and back frame 111 by readily releasable and readily securable fasteners.
Important as is the structure so far discussed it is certainly of no greater importance than the removable upholstery feature now to be discussed or than the cushion structure to be discussed later. While the panels 103 and 104 and the frame members 110 and 111 can be made without upholstery to look very good, the panels 103, 104 and 111 are usually upholstered, and the present invention makes it possible to remove the upholstery and quickly to put it back or to put on new upholstery, as explained in the introduction.
A close fitting upholstery cover 200 for either side panel 103 or 104 both sides of both the vertical portion 105 with aportion 20], covers the arm 107 with an arm portion 202 and covers all the edges, 108 and 109, and nearly all of the edge 106.
The seat-and-back cushions 102 are fully reversible, and each comprises a seat portion 270 and a back portion 271 joined together, as by cloth hinges 272. Each portion 270, 271 has an outer case 273 or 274, usually of upholstery fabric, containing a muslin inner case 275 or 276 (FIGS. 7 and 9). The inner case 275 or 276 may contain filler such as feathers, down, polyester, other synthetic fibre, or cotton batting 277 and foam rubber or foam plastic 278. The inner cases 275 and 276 are sewed together along lines 280 and 281 connecting them to the cloth hinges 272. A stiffening insert 282 (see FIGS, 9 and 10) for the back cushion 271, made of plywood, fiberglass, paper fiber, steel, aluminum or something of that nature, is inside the foam member 278 for the back and is secured to the seat portion 270 by the fabric hinges 272, to which it is riveted. This stiffener 282 supports the thorax region of a persons back (see FIGS. 7 and 8) and extends higher than the sofa back portion 121, so that the sofa 100 is still comfortable even though the back 121 and the arms 107 are at the same level. The stiffener 282 is preferably made to be flexible enough to provide a curvature that gives contouring support to the lumbar region of the back. The fabric hinges on tabs 272 on the stiffener panel 282 are sewn through as the cushion is sewn through, that is, from the top surface to the bottom surface. The stiffener panel 282 is used to prevent the back of the panel from moving forward at its bottom and thus decreasing the effectiveness of the thorax support. Zippers 283 and 284 may be used for closing the cases 273 and 274, and are separable, as in a coat-type zipper, so that both pieces of upholstery separate and come off. As in the'arm panels, this separation gives a little loose length of fabric near each end which is not bound by the non-stretchable zipper tape.
are still made substantially as shown, except that the high back model needs no stiffener panel 282. On all models, the seat cushions 271 are preferably cantilevered beyond the fronts of the seat frame 110. This, of
course, is not essential, but when done adds to the comfort of the sitter by imparting a variability in the distance from the front edge 285 to the back cushion 271,
so that both short and tall people find that it adjust properly to thigh length.
Somewhat of the functions of the seat cushions 102 are shown in FIGS. 7 and 8. Note that the cushions 270 and 271 of the heavier man may depress more than those of the lighter woman, because of the size and weight differences. This action makes the cushions automatically comfort-adjustable to each person. Also note that the seat cushion 270 compresses back from its front edge 285. The back insert 282 is necessary only for the low-back models, though it can'be used in all types.
FIG. 11 shows the sofa 100 folded for shipment, ready for its carton. The back frame 111 folds over or under the seat frame 110, which is then placed over the panels 103 and 104. The cushions 102 are placed around as padding. It can be appreciated that the package is much smaller than the sofa. The upholstery covers 200 etc., can be-included in the same package or can make up a different package. The covers 200, 220, 273 and 274 are usually identical in fabric but they can be different if desired.
To those skilled in the art to which this invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. The disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
