5 Claims. (Cl. 5-351) The present invention is directed to a mattress, and more particularly to a mattress which enables relatively rigid springs to be utilized and yet give the effect of a relatively soft mattress.

In recent years, the use of so-called hard mattresses has increased greatly. Frequently, such mattresses are prescribed by physicians for patients having ditficulties with their backs. Such hard mattresses have relatively rigid springs and do not accommodate to the weight of the user. a

Many persons have found such hard mattresses to be most uncomfortable, with the result that the normal sleeping habits of such persons have been interfered with.

This invention has as an object the provision of a novel mattress.

This invention has as another object'the provision of a mattress having relatively rigid springs, but presenting the feel of a relatively soft mattress. i i

Other objects will-appeanhereinafter, I i

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it beingunderstoocl, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Referring to the drawings, wherein like reference characters refer to like parts: I

Figure l is a perspective view of the mattress of the subject invention.

Figure 2 is a cross-sectional view of the mattress of the subject invention taken on line 22 of Figure 1.

The mattress of the present invention is designated generally as 10. The mattress comprises the spring unit 12, the top pillow portion 14, and the bottom pillow portion 16. Since the top and bottom pillow portions 14 and 16 are identical, my description will be confined to the top pillow portion 14. However, it is to be understood that the description of the top pillow portion 14 is equally applicable to the bottom pillow portion 16.

The spring unit 12 includes a plurality of coil springs 18 of conventional construction clipped to top and bottom wire frames 19 of conventional construction. A wide variety of coil springs 18 may be utilized in the mattress of the subject invention, and no particular claim as to any type of coil spring construction is made herein. Preferably the coil springs 18 should be relatively rigid so as to confer upon the mattress 10 the property of constituting a mattress of the hard type.

The spring unit 12 is encased within a top pair of sisal pads 20 and 21 and a bottom pair of sisal pads 22 and 23. A stabilizing anchorage member, such as a Permalator (a pair of parallel twine strands connected by wire crosspieces), is provided intermediate each of the top and bottom pairs of sisal pads.

Since the mattress 10 is symmetrical above and below the spring unit 12, the description herein will be confined to the portion of such mattress 10 above the spring unit 12.

The Permalator 24 intermediate the sisal pads 20 and 2,975,437 Patented Mar. 21, 1961 21 serves to distribute forces exerted on the sisal pads 20 and 21 and to prevent bunching up thereof. The sisal pad 21 is wider than the wire frame 1?, sisal pad 20, or the Permalator 24, the width of the sisal pad 20 and Permalator 24 being that of the wire frame 19, so that the ends of thesisal pad 21 embrace the Permalator 24, sisal pad 20 and wire frame 19. The overlapped end portions are joined together by the staples 25. Such staples 25 pass through the top part of sisal pad 21, the Permalator 24, the sisal pad 20, the wire. frame 19, and

. the bottom part of sisal pad 21.

Felt layers 26 and 28 are disposed on the outer surfaces of the sisal pads 21 and 23.

Since the felt layers 26 and 28 are identical, a description of felt layer 26 will be adequate for an understanding of the present invention.

The felt layer 26 is wider than the sisal pad 21, so that the ends of the felt layer 26 embrace the ends of the sisal pad 21. The felt layer 26 is supported by the sisal pad 21, the Permalator 24, the sisal pad 20, and the wire frame 19. The anchorage of the felt layer 26 to these elements will be described below.

The top pillow portion 14 comprises a quilted assembly of the outer ticking 30, felt 32, and muslin layer 34. The quilting stitching 36 extends through the ticking 3i. and the muslin layer 34 and serves to hold the top pillow portion together, preventing bunching up of the felt, the muslin layer 34 serving as an anchor for such quilting stitching.

The amount of felt within the felt portion 32 of the. top pillow portion 14 is adjusted so that such top pillow portion .14-confers a sufficient degree of softness upon the mattress 10 without interfering with the therapeutic quali-i 14 to the ticking 30. The flap 40 comprises the side of the top pillow portion 14.

The flap 40 is sewn to the two additional llaps 42 and 44 by the stitching 46. The stitching 46 is disposed at the innermost ends of the flaps 40, 42, and 44, such innermost ends being thereby concealed from view.

The flap 42 projects laterally and is joined to the binding tape 48. Binding tape 48 is connected to the side ticking 50 of the spring unit 12. The flap 42 and the side ticking 50 conceal the flap 44 and the interior of the spring unit 12.

The flap 44 is anchored by staples 52 to the sandwich of: the top end portion of the felt layer 26, the top end portion of the sisal pad 21, the Permalator 24, the sisal pad 20, the top wire frame 19, the bottom end portion of the sisal pad 21, and the bottom end portion of the felt layer 26. This anchorage holds the top pillow portion 14 in position, preventing the lateral shift of such top pillow portion 14. Thus, the top pillow portion 14 may be entirely anchored to the spring unit 12 by the flaps 44. Such anchorage is readily and rapidly accomplished by stapling. Thus, the need for relatively costly stitching is entirely eliminated.

As used hereinafter, the flap 40 may be referred to as a first flap and the fiap 44 may be referred to as a second flap. Hereinafter, the flap 42 and the side ticking 50 may be referred to as a side ticking flap.

It is to be understood that a wide variety of changes may be made in the mattress of the present invention. For example, a wide variety of springs may be used within the spring unit, and a wide variety of materials QWAQ? may be used to replace the Pei-malator, felt, muslin, and sisal above-referred to.

The present invention may be embodied in other specific forms without departing from the spirit or essen;

tial attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the fore going specification as indicating the scopeofthe invention. I claim: 1.
