2 Claims. (Cl. 5--351) This invention relates generally to bed mattresses and box springs and more particularly to an improved mattress or springs having a exible attractive cover wh-ich will not wrinkle. v

It is an object of this invention to provide an improved mattress or springs in which the yieldable mattress or spring interior is conlined in an improved cover means which is dustproof, will not wrinkle, and which may have a pattern molded therein.

It is a further object of this invention to provide a mattress or springs of the aforementioned type in which no buttons are necessary to retain the cover against shifting movement, wrinkling or distortion.

It is a still further object of this invention to provide a mattress or springs in which the cover can be easily and quickly secured around =a yieldable filling material While at the same time the dimensions thereof can be accurately controlled so that the mattress or springs will be of the proper size and shape, will be properly filled, and will not Wrinkle or bulge.

These and other objects of this invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawing, in which:

Figure 1 is a perspective view of a mattress of this invention;

Fig. 2 is an enlarged sectional view of the structure illustrated in Figure l, taken along the line 2 2 thereof;

Fig. 3 is an enlarged sectional View of the structure illustrated in Fig. 2, taken within the area of the circle 3 thereof; and

Fig. 4 is an enlarged sectional view of the structure illustrated in Figure l, taken along the line 4-4 thereof.

Referring now to the drawing it will be seen that only a mattress is illustrated, but the invention Iis equally applicable to box springs or the like. The mattress includes any `conventional yieldable interior or filling means shown in the form of coil springs 6, and cotton padding 7 above and below the springs. It will, of course, be appreciated that the mattress could be lled with other suitable material such as foam rubber, or the like. A mattress cover 9 contines the yieldable springs and padding, and as shown includes a top portion 11, bottom portion 13 and a side portion 15. The side portion 15 is joined at 17 along a vertical line to provide a closed periphery for the mattress and the top and side portions 11 and 13 respectively are suitably stitched or otherwise connected to the side portion at 19 to provide a complete mattress cover confining the inner springs and padding. Each of the cover portions 11, 13 and 15 includes an inner sheet 21 made of cotton or the like, which is bonded to the inner surface of a sheet of foam rubber 23. An outer cloth sheet 25 -is disposed against the outer face of the sponge rubber sheet 23 and bonded thereto along predetermined paths 27 to provide `any desired pattern in the outer sheet of the mattress, such as illustrated in Fig. l. The outer sheet 25 may be of any suitable cloth but preferably is of a knitted material such as rayon or nylon, or a suitable acetate material which will be attractive in ice appearance, smooth inxnish, andi whichwill' not, when sealedorbonded!tottherubber, harden, scar or crack'. 'Ilh'e outer sheet-25i may-bey bond'edj tothe sponge rubber by anyf suitablec method; one"` such:` methodi being., to spray the underf side otthe sheet25 with a suitableplastic-and then passing the sheet` 252 and` the sponge rubber sheet 23, with the backing sheet 21 already secured thereto, into heated dies having embossed or raised portions which mold the desired pattern in the outer sheet, while at the same time securing the outer sheet to the sponge rubber sheet along the mold or pattern lines. Also, with this process the sizes of the upper, lower and side portions can be `accurately controlled and the various mattress cover portions can be molded to size during the molding operation, so that no cutting or sizing -is necessary when the mattress is being assembled. Assembly costs and problems are thus reduced and a more attractive mattress, having the pattern molded therein, can be produced.

The yieldable interior of the mattress may be either slipped into the .cover or the cover secured around the springs and padding. In any event, the cover should be adequately lled so that there will be no voids therein and so that the-outer sheet 25 will be slightly stretched and thus maintain a smooth surface condition. Due to the use of the sponge rubber sheet and the knitted fabric the entire cover is elastic and can stretch and then recover after stretching so that there will be no wrinkles therein. That is, even after a person lies or sits on the mattress, as soon as the weight is removed therefrom the elastic cover will return to its initial form with no wrinkles or depressions therein.

Furthermore, because of the elastic quality of the cover, no buttons are necessary to retain the cover in its proper position and against distortion, such as is the case with ordinary cotton covers which will not stretch or recover. Thus, by using an attractive cover having a molded pattern therein which will not wrinkle, the mattress cover can be as attractive as an upholstered piece of furniture and need not always be lcovered by bed spreads or the like. Furthermore, with the provision of the sponge rubber in the cover, the cover is dustproof and allergyproof.

Still further, it will be appreciated that companion box springs to a mattress of this type may be covered with the cover material previously illustrated and described. Thus the mattress of this invention is far more attractive, more comfortable, and has greater durability and life than any heretofore known.

What is claimed is:

1. A mattress or box spring construction, including cover means and yieldable means confined within said cover means, said cover means yincluding a top portion, a bottom portion, and Ia side wall-like portion, each of said portions being interconnected to provide a complete cover means conning sai-d yieldable means, each of said portions including an outer sheet member, an inner sheet member, and a sheet of ilexible material disposed between said inner and outer sheets, said inner sheet member being bonded to one side of said yieldable sheet to provide a backing therefor, said outer sheet member being bonded to the opposite side of said yieldable sheet along predetermined pressure paths so as to adhere said outer sheet to said yieldable sheet and provide a pattern of indented paths on said outer sheet.

2. A mattress or box spring construction including a stretchable and llexible cover means, and yieldable means confined within said cover means, said cover means including interconnected top, side and bottom portions which define a complete cover means to coniine said yieldable means, each of said cover means portions including an outer sheet member formed of knitted cloth, an inner cloth sheet member and a sheet of sponge rubber disposed between said inner and outer sheets, said inner sheet being bondedto' one side of said spongerubber sheet to provide a backing therefor, said outerl sheet member being bonded to said sponge rubber sheet along predetermined paths, which paths are disposed below the outer surface of the adjacent unbonded portions of saidl outer sheet member to provide a pattern on said outer sheet member, said cover meanstghtly confining said yieldable means and providing a exible mattress cover which will return to its initial position after being depressed, such as when supporting a human body or the like.
