mvENToR gr J. KAPLAN ELECTRICALLY HEATED COMFORTER Filed Nov. 10, 1954 April 19, 1955 United States Patent -O ELECTRICALLY HEATED COMFORTER Julius Kaplan, Bronx, N. Y. Application November 10, 1954, Serial No. 468,002 3 Claims. (Cl. 219-46) This invention relates to improvements in an electrically heated comforter.
The principal object of the invention is directed to the provision of a comforter having upper and lower unitary sections, each resembling a comforter with the inner portion thereof secured to what may be called a heating layer thereby to form an electrically heated comforter.
According to one novel feature of the invention, the securing of the sections and heating layer is accomplished in such a manner that the securing means is not visible as would be the case were the sections and layer secured together by stitching extending completely through the Components.
According to another novel feature of the invention, the sections may be made up separately and have the desired stitching for quilting which may be alike or different, as may be desired. Also, as the sections are separate components and are secured together internally, the comforter is more tlulfy than is the case where the stitching extends through all of the superposed layers.
As a further feature of the invention, each of the sections is filled with synthetic fibers which are lighter and warmer than wool, are as light if not 'lighter than down, are resilient, do not mat down, and are washable and non-flammable.
All of the above objects I accomplish by means of such structure and relative arrangements of parts, as will fully appear by a perusal of the description below and by various specic features which will be hereinafter set forth.
To the above cited and other ends and with the foregoing and various other novel features and advantages and other objects of my invention as will become more readily apparent as the description proceeds, my invention consists in certain novel features ofL construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:
Fig. 1 is a plan view of one of the sections of the comforter;
Fig. 2 is a forter;
Fig. 3 is an enlarged plan view of a portion of the heating layer shown in Fig. 2;
Fig. 4 is a partial sectional View` through the sections of the comforter to explain how they are secured together; and n Fig. 5 is a small scale plan view of the comforter.
Referring now to the drawings more in detail, the invention will be described.
A section of the comforter is shown in plan in Fig. l wherein an outer member 2 is provided which may be a fabric such as satin or the like. An inner member 4 may be a loosely woven fabric such as a cheese cloth or tobacco cloth.
A tie strip 6, which may be a tape, cord or the like, is laid on the inner member 4 so as to provide runs thereof, as shown.
Filling, preferably of synthetic fibrous material, is laid over the tie strip 6 and inner member 4 and the outer member is disposed thereon.
The outer and inner layers, with the llirig therebetween, are quilted, as by stitching as indicated at 8, to secure the components together. The quilting may be plan view of the heating layer of the comarranged to form a predetermined pattern or design, as desired.
Instead of a single plural shorter lengths.
The tie strip or strips are secured in the section at points where the quilting stitching crosses the strip or strips, as indicated by 10. The lines of quilting stitching are several inches apart, say six or eight, wherefore the tie strip is secured every six or eight inches. The strip, between its points of securement, may be cut so as to provide lengths or ends for tying purposes, as will appear.
The section 2 for convenience will be referred to as an upper section. There will be a similar'section called a lower section indicated by 12 in Fig. 4. This will have outer and inner members 14 and 16 between which is filling and a tie strip or strips with stitching for quilting as described. The components of the lower section will be similar to those of the upper section.
The upper and lower sections are secured together with the inner members thereof innermost. Heating means is disposed between the sections and is in the form of suitable wire associated with a heating layer or with the inner member of one of the sections.
In Fig. 2, a heating layer is represented by 20 and a heating wire or element 22 is secured thereto by passing it back and forth through the layer so as to provide stretches or runs 24 on opposite sides of the layer 20.
The layer 20 will be formed from loosely woven fabric which may be cheese cloth or the like and it may be provided with holes 26 for the passage of the wire therethrough if desired or necessary.
The heating element will be arranged in a predetermined pattern such as will correspond or come within the area of the quilted portion of the sections and will be arranged so -that stitching through the sections for quilting will not injure the wiring.
In assembling the sections, the layer 20 may be disposed between the inner members of the sections but it may be desired to associate the wiring directly with the inner layer of one of the sections as shown in Fig. 2.
In lthe latter case, the tie strip or strips of the sections are cut between the points of fastening by the quilting stitching. The inner members being loosely woven and the tie strip being on the inner side or on top of the inner members, this is possible. As the tie strip is cut, ends such as indicated by 30 in Fig. 4, are provided. These are brought through the inner members.
With the inner members disposed on one another, the ends of the tie strip are tied together thereby 4to secure the sections together. There may be as many ends of the tie strip as may be desired and the tying for securing the sections together is advantageous in that by untying the tie ends the sections may be separated if desired.
Where a separate heating layer such as 20 is used, it is disposed between the inner members of the sections. With the tie strip severed -to provide the ends for tying, those ends from the the inner member of one section are passed through the member 20 and are tied with the ends of the other section.
With the sections secured by the tie ends in superposed relation, marginal edges thereof are secured by a binding therearound or are stitched as at 34 in Fig. 5.
It may be desired to provide a flap 36 extending from one margin of the comforter. This will be made from fabric which will not readily slip for tucking beneath the mattress in dressing the bed.
It will be noted that the comforter is formed from a pair of sections, each comprising an outer decorative member and an inner member with filling therebetween, which members are quilted. Inner members of the sections are secured together by tie members so that they may be separated if desired.
The heating wiring between the sections is arranged so as to be disposed between the sections and within the area of the quilting. The filling will consist of synthetic fibers which are light in weight, are nonammable and possess great warmth.
-The invention may be embodied in other specific forms without departing from the essential characteristics thereof. .Hence, the present embodiments are therefore to be considered i'n all respects merely as being illustrative and length of tie strip 6, there may be not as being restrictive, the scope of the invention being indicatedbythe appended claims rather than by the fore going description, and all modications and variations as fall within .the meaning and purview and range of equivalencyof the1appended claims are therefore intended to be embraced therein.
What it is desired to claim and secure by Letters Patent of the United States is:
1. An electrically heated comforter comprising, an upper section having an inner and outer member and filling therebetween and provided with lines of stitching therethrough to form quilting within a certain area there of, a lower section having an inner and outer member and filling therebetween and provided with line of stitching therethrough to form quilting within a certain area thereof, the stitching connecting the inner and outer members of lsaid upper section being of a pattern nonconforming with the pattern of stitching connecting the inner and outer members of said lower section and an electrical heating element secured to the inner member of one of said sections, said sections being secured together by stitching passing through said upper and lower sections without the said certain arcas thereof.
2. The device of claim 1 having tie strips secured to the inner member of each of said sections to hold said sections in comforter forming relation.
3. The device of claim 1 having securing means secured to the inner member of each of said sections to hold said sections in comforter forming relation.
