Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to a knitted fabric which is braided into a cylindrical shape, metal resistance wires are appropriately knitted between courses, and which is connected to a power source to generate heat, and furthermore, Specifically, the present invention relates to a cylindrical heat-generating knitted fabric that achieves therapeutic effects by being attached to a desired part of the body and heating it.

b. Prior Art Conventionally, heating pads have been known as heating pads, which heat the desired parts of the body or affected areas by applying them directly to the heating pads, but most of them are plain woven and have heating metal wires between the ground yarns of the wefts. Since the parallel ends of each metal wire are woven in a zigzag pattern as warp threads and connected with lead wires, each metal wire is connected in parallel to the power source, and this heating pad lacks elasticity, so it does not adhere well to the body or affected area. This was a cause of poor treatment efficacy. In addition, not only does the connection of the metal wires pose a problem during work, but the metal wires may break depending on the frequency of use, making it impossible to obtain the desired amount of heat.

c. Purpose of the Invention The present invention is intended to solve the drawbacks of this type of heating element according to the prior art, and to solve the problems of this type of heating element according to the prior art. A metal resistance wire is also woven into the metal resistance wire, and by connecting the metal resistance wire to form a series electric circuit from a power source, it has extremely high resistance to expansion and contraction, and has excellent adhesion to desired parts of the body and affected areas.
The purpose is to be able to perform desired heating without falling off from any part, to be easy to connect to the metal resistance wire, and to eliminate problems such as breakage due to frequent use.

d Structure and operation of the invention The structure and operation of the present invention will be explained below with reference to the drawings.

First, to explain the conventional example shown in FIGS. 1 to 3, a planar heating element 1 has a conductive wire 2 woven in a zigzag pattern between weft threads 3 with conductive wires 2 as warp threads.
The parallel ends of are connected with a lead wire 4. Therefore, each of the conductive wires 2 serving as warp threads are connected in parallel between the power cords 5.

In the above planar heating element 1, since the weft threads 3 have slight elasticity, there is slight elasticity in the weft direction, but since the warp threads are conductive wires 2, there is elasticity in the warp direction. It's impossible. Therefore, the sheet heating element 1 does not come into close contact with the main part of the body, reducing the thermal effect, and if the main part of the body is an affected part such as a bending joint, it may fall off from the affected part. This caused a loss in the therapeutic effect. Furthermore, since the two ends of the conductive wire are connected by the lead wire 4, the work becomes extremely difficult. Furthermore, if the planar heating element 1 is repeatedly bent, the conductive wire 2 will break due to tension, making it impossible to obtain the desired amount of heat.

The figure is an enlarged perspective view of the case where the metal resistance wire 7 is a stranded wire. It is preferable to use 60 micron diameter single wire as twisted wire. Alternatively, a metal resistance wire containing a composite of the metal resistance wire 7 and a fiber thread may be used.

It becomes 5W.

e Effect of the Invention The cylindrical main body 6 of the present invention has the same expansion and contraction as the weft knitted fabric because the metal resistance wire 7 is simultaneously braided into the weft knitted fabric knitted using a circular knitting machine and a flat knitting machine. The braided metal resistance wire 7 becomes a flexible metal resistance wire 7, and even when the weft knitted material is stretched to its maximum extent, the braided metal resistance wire 7 does not stretch completely and has a margin. Therefore, disconnection due to tension can be prevented. Moreover, when the cylindrical main body 6 is attached to an important part of the body, the contractile force causes it to adhere closely to the uneven surface of the body, thereby preventing it from falling off. Further, since the metal resistance wire 7 is a thin wire, it is buried in the fiber thread 12, and when the cylindrical main body 6 is attached to an important part of the body, there is no feeling of a foreign body. Even people with sensitive skin will not get a rash because sweat from their bodies is absorbed by the fiber threads 12.
Other benefits include the low voltage, so there is no risk of electric shock, and the braided metal resistance wire 7 prevents low-temperature burns, has excellent heat retention and breathability, and is easy to wash. It is something.
