United States Patent 3,259,925 SELF-WARMING CUSHION Michael Tilles, 1514 Oak St., Alameda, Calif. Filed Mar. 1, 1965, Ser. No. 436,119 2 Claims. (Cl. -355) The present invention relates to improvements in a self-warming cushion and it consists in the combination, construction and arrangement of parts as hereinafter described and claimed. I

An object of my invention is to provide a self-warming cushion that makes use of an insulating material known as Styropor which has the ability to reflect the temperature of the body that contacts it. This material is placed at the top of the cushion and when a person sits on the cushion, his 'body heat will be reflected by the material and he will feel the heat within a few seconds. A layer of resilient material underlies the layer of Styropor and this is to make the cushion more comfortable to sit upon. The layer of resilient material may be Polyester. Under the layer of Polyester I place a layer of waterproof material such as rubber or an impervious synthetic such as a flexible plastic.

The two layers of material, Styropor and Polyester, and the layer of waterproof material are held together by adhesive strips and are enclosed in a casing preferably made of fabric. The cushion may be of any size desired. One handy size is a cushion fifteen inches square. The layer of Styropor is about five-sixteenths of an inch thick and the thickness of the layer of Polyester is about fifteensixteenths of an inch. The waterproof layer may be one-eighth inch thick. I do not want to be confined to these exact measurements. The cushion is designed to be folded in half when not in use and carrying handles are permanently secured to opposite sides of the cushion and are useable for transporting it while in folded position.

The cushion is simple in construction and is durable and efiicient for the purpose intended. It can be laid on a wet seat and the waterproof layer will prevent water from passing into the layers of Polyester or Styropor and soaking them.

Other objects and advantages will appear as the specification continues. The novel features of the invention will be set forth in the appended claims.

For a better understanding of my invention, reference should be made to the accompanying drawing, forming part of this specification, in which:

FIGURE 1 is a plan view of the cushion shown in open position.

FIGURE 2 is an end elevation of the cushion shown in folded position.

FIGURE 3 is an enlarged transverse section through the cushion and is taken along the line 3-3 of FIG- URE 1.

FIGURE 4 is an enlarged section of a portion of the cushion showing it in folded position.

While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claims without departing from the spirit thereof.

Detailed description In carrying out my invention I provide a cushion that is preferably formed into two similar halves indicated generally at A and B in FIGURE 1. Each half has a top layer of Styropor C and a lower layer of Polyester D. The top layer of Styropor C has the ability to reflect the heat from the persons body who is sitting on the cushion. It only requires a few seconds of time for the person sitting on the cushion to notice the heat and ice the cushion will feel warm to him. The under layer D is for the purpose of providing a semi-resilient support for the Styropor upper layer C. I also provide a bottom waterproof and flexible l-ayer H, that underlies the layer of Polyester D.

The two halves A and B of the cushion each contain the upper layer of Styropor, the under layer of Polyester, and the bottom Waterproof and flexible layer H. I have shown the two halves A and B of the cushion in FIGURE 1 as being of the same size although this does not have to be the case. In the form of the device shown in the drawing, the two halves A and B of the cushion when in open position form a cushion that issquare and whose sides are fifteen inches each.

A fabric casing E encloses the layers C and D and H of each half. Pieces of adhesive tape J are used to secure the three layers C, D and H of each half cushion A and B, together. This flexible fabric casing has a cover portion 1 that extends over both halves A and B and connects these two into a single unit with the two halves being swingable from open position into a folded position. The half A of the cushion has a side wall 2, end walls 3 and 4 and an inner wall 5, see FIGURE 3. In like manner the other half B has a side wall 6, end walls 7 and '8 and an inner wall 9. FIGURE 3 shows the inner walls 5 and 9 of the halves A and B as being connected to the undersurface of the cover 1 by a row of stitching 10 which is clearly shown in FIGURE 1.

This construction permits the two halves A and B of the cushion to be swung from open position shown in FIGURES 1 and 3 into closed position shown in FIG- URES 2 and 4. When the cushion is in closed position, the two inner walls 5 and 9 for the halves A and B, respectively, lie in the same place and the two halves of the cover 1 will be folded along the line of stitching 10. The bottom wall 11 of the half A and the bottom wall 12 of the half B will contact with the waterproof layers H. Also these bottom walls 11 and 12 will form the outer walls of the cushion when the latter is in folded position.

To facilitate the swinging of the halves A and B from full open position to closed position, I provide the half A with a handle F and the half B with a handle G, see FIGURES 1 and 2. The handles F and G. may be made of any material desired and are preferably formed from cloth. The handle F is secured to the side wall 2 of the half A and the handle G is secured to the side wall 6 of the half B. The handles can be used for carrying the cushion when in folded position.

The fabric casing E for the two halves A and B encloses the top layers C of Styropor, the under layers D of Polyester and the bottom waterproof layers H of rubber or flexible plastic, as clearly shown in FIGURE 3. The cushion may be used for all manner of purposes and it could be made large enough so that the half A would constitute the portion for a person to sit upon and the half B would constitute a back portion against which a person could lean The cushion is light in weight and and is readibly transportable, especially when it is folded in half for carrying purposes as shown in FIGURES 2 and 4. The cushion can be placed on a wet bleacher seat or on a wet bench and the waterproof bottom layer will prevent water on the seat or bench from reaching the layers D and C, and soaking them.

The product Styropor which makes up the layer C, is a trademark for a polystyrene containing a blowing agent. The product is made by a Swedish company whose name is Badische Anilin & Soda-Fabrik AGs, and whose address in Sweden is Ludwigshafen am Rhein. The Polyester which makes up the layer D, is a polyetherbased urethane foam.

I claim:

1. A foldable cushion comprising two laminated sections, each section embodying a top layer of flexible heatreflecting material an intermediate layer of resilient flexible materialand a bottom layer of flexible waterproof material, a unitary casing enclosing both laminated sections to provide at least one relative smooth continuous and uninterrupted surface extending over 'both sections with the diametrically opposite surface of said casing encompassing each section of said cushion independently of the other.

2. A fold-able cushion as set forth in claim 1 wherein said diametrically opposite surface of said casing is secured to the first-mentioned surface between said sec- References Cited by the Examiner UNITED STATES PATENTS 1,593,066 7/1926 Gaston 297180 1,802,853 4/1931 Welxtner 297378 1,927,331 9/1933 Wibtoofi 297229 2,630,620 3/1953 Rand 5-347 X 2,734,556 2/1956 Hebrank 51--141 2,792,875 5/1957 Pirrone 297-252 3,032,916 5/1962 Oakes 297219 X CASMIR A.
