Hereinafter, embodiments of the present invention will be described.
A flexible sheet is used, and the main body is called a flexible sheet. The wavy line (6) around the flexible sheet also means that it is loose or separated, and that the width is within the selection range. The two straight lines (7) inside the wavy line indicate a reference range of the width on the knee, and the area between the straight lines is referred to as a cover portion (8). After that, the wavy line part may not be drawn.
Although it may be composed of several layers, it will be mainly described with two sheets, the upper first sheet (1) and the lower second sheet (12). One sheet may be folded or two sheets may be stacked. In either case, there is a front and back on the first sheet side and a front and back on the second sheet side, and it has at least four surfaces.
Since the cut end (5) penetrates the flexible sheet, the cut end inevitably occurs at two places, the front side (2) of the first sheet and the back side (3) of the first sheet.
The shape of the center line (15) includes a single line to a strip shape of an arbitrary width, and two flexible sheets, upper and lower, are joined at this position as needed.

A flexible sheet with a rectangular shape is mainly used.
The structure will be described with reference to FIGS. 1 to 5.
The case of only the first sheet (1) will be described with reference to FIG. There is a front side (2) of the first sheet and a back side (3) of the first sheet, and the left end is shown as the upper end (4). The same applies to FIGS. 3, 4, and 6 below in this direction. a is a case where the cut end (5) having a horizontal single character shape is provided and the upper end shape is straight. There is a wavy line (6) around it, and inside the wavy line there is a cover (8) between two straight lines (7). b is a case where the deformation of a has two cuts and the middle side of the upper end is curved.
FIG. 2 will explain a development view in the case where the first sheet and the second sheet (12) are doubled.
When it is bent at the upper end position in the shape of a ring (11) and completely overlapped, it is similar to FIG. 1b in the previous figure. A tape (9) or a fastener (10) is used in the middle of the one-letter cut, and the cut is separated into two places with the vertical center line (15) as the target axis. When the visible side is the back side, the visible side is the back side (14) of the first and second sheets, and the invisible side is the front side (13) of the first and second sheets. The center line is shown by a broken line, but the center line is sutured as needed.
In some cases, the first sheet is cut into upper and lower sides, and then the parts other than the cut end are joined. In this case, there is also a method of joining the upper and lower parts, such as adding tape to the left and right sides.

FIG. 3a is a perspective view in which the state of FIG. 2 is about to be bent, and the back side (14) of the second sheet (12) can be seen. b is a case where the shape of the cut end (5) is a concave curve shape and the mouth is a convex curve shape. c is an enlarged view in the case where the semicircular hand cover (16) is attached to the cut end of the diagonal straight line in the shape of C. The straight line is the cut end, which is the joining line with the hand cover. Since the flexible sheet is soft in nature, it requires a hand cover and edging at the cut end. The illustration of the edging is omitted.
In FIG. 4, the bent position is set as the upper end (4), and the center line (15) of the double-layered flexible sheet, the two straight lines (7) or the left and right lines, and the drop stop (27) or the upper end. This is a case where a large bag (40) is provided by joining the upper and lower sheets in parallel lines.
In FIG. 5, the second sheet has a receiving portion (20) consisting of a front portion (19), two side portions (18), and a bottom portion (21), and the surface side having no cut end is the rear surface portion. It is the figure provided in the cover part of the rear surface part. The side closer to the upper end is on the insertion port (17) side of the receiving portion. The number of insertion ports of the receiving portion may be increased by providing a center line in one receiving portion or providing a second stage. Use mesh or light fabric. A receiving portion may be provided in the large bag.

FIG. 6 is a usage diagram during bending, and for convenience, the abdomen (22), arms (23), and knees (24) are divided from above the main body to explain how to use them. The main body should be long enough to reach your feet. The heating material and the exothermic material are collectively referred to as a body warmer, and the cases of both non-adhesive body warmers (25) and adhesive body warmers (26) will be described.
In a, two receiving parts (20) are provided on the back side (3) of the first sheet, and a non-adhesive body warmer is inserted. In b, the left part is narrower than the two straight lines (7) and the two straight lines. The upper and lower two sheets are joined with a line (28) or right part line (29) and a drop stopper (27) to prepare for protrusion or drop, and several adhesive body warmers can be attached to the back side of the second sheet (12). Is attached.
FIG. 7 is an overall view in use.
When a is in the attached state and the work is not performed by hand, put the arm from the hand into the large bag (40) from the cut end. At this time, even if the force is released, the left and right ends of the cut end serve as stoppers and the hand can be fixed. For that reason, it is necessary to soften and strengthen the overhang of the cut end. The length is adjusted by contracting the abdomen.
Reference numeral b is a state in which the upper end (4) position is aligned with the abdomen and the left and right ends of the main body are inserted into the back side of the leg to wrap the knee before setting when the flat portion (30) is provided.
c is a state in which the left and right flat parts are inserted below the knees or under the buttocks. The flat part can be detachably joined with a face tape or the like, or the flat part can be sewn by sticking out to the main body from the beginning. However, since the weight of the inserted hand prevents the main body from falling, the presence or absence of a flat portion is a selection range.

From the usage diagrams of FIGS. 8 and 9, other methods of making and using are described.
In FIG. 8a, a removable surface tape (31) is provided in an apron shape and wrapped around the waist to fix it, and then the user moves to standing work or sits down to work on the desk. Extend the upper left and right sides to provide a new place where the body warmer can be inserted at the place where it hits the waist. The left and right ends of the hem of the main body may be provided as hemming points (32) excluding the corners.
b is a state in which it is being worn from the rear side when it is intended to be worn as a shoulder strap. A sash or sleeve (33) for passing the arm may be provided on the upper end side.

In FIG. 9, another type of arm holding portion and an overall supplementary explanation will be given.
A is a state of use when a pseudo large bag (40) similar to FIG. 4 is formed, and another sheet is added to provide a semi-elliptical shape or an upward insertion port (34) which becomes a semi-elliptical shape at the time of use.
b is a semi-transparent usage diagram. An upward insertion port, a side surface portion (35), a bottom surface portion upper stage (36), a bottom surface portion lower stage (37), and an accessory portion (38) such as a hole, a valve, or a partition held between them are shown. The presence or absence of the upper part of the bottom part is optional.
c is a case where the arm holding portion (39) is provided by folding in a fold shape, and the position of the lower part of the bottom surface portion is indicated by a broken line. Join to the surface of the first or second sheet at a necessary and sufficient place for the left and right side sides.
To use, insert the arm from the insertion port of the arm holding part. Insert your body warmer or belongings through the hole in the upper part of the bottom or the gap in the valve.
Others are supplemented.
Border the cut end (5). Also, prepare the hand cover (16) shown in FIG. 3c as a separate tool, and fasten it to the lower side of the cut end with face tape. This strengthens the cut. In addition, it is better to reinforce the cut end and the cut end so as to hold the arm.
Here's another way to use it.
You can insert a body warmer and use it as a cushion, and if you want to use it as a cushion, fold it to an appropriate size and lay it under your buttocks. Wrap it with the back side facing up and use it as a hot water bottle. Prepare a wrapping cloth and shape it. The wrapping cloth may be in the shape of a stuffed animal.
