Abstract

PURPOSE:To provide an electric blanket which is soft and has good productivity by installing an electric heater wire in the blanket without using an adhesive. CONSTITUTION:A holding cloth portion 6 of plain wave or the like is formed by a pair of holding threads 7 in that portion of the ground weave 2 of a warp knitted blanket in which an electric heater wire 8 is disposed. The electric heater wire 8 is passed through space portions 9, 10 and held by the holding cloth portion 6, the space portions 9, 10 each being formed by the holding cloth portion 6 between the holding cloth portion 6 and the ground weave 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric blanket in which electric heater wires are arranged on a warp-knitted blanket.

0002

2. Description of the Related Art In recent years, electric blankets in which electric heating wires are arranged in warp knitted blankets, particularly Meyer knitted blankets, have become extremely popular. In such an electric blanket, the electric heater wire is sandwiched between two blankets and attached to the blankets by adhesive.

0003

[Problems to be Solved by the Invention] However, the conventional electric blankets as described above have poor texture due to the use of adhesive, and are also poor in productivity.

[0004] In view of these conventional problems, the present invention has been developed to provide an electric blanket that allows electric heater wires to be attached to the blanket fabric without using adhesives, has a good texture, and is highly productive. I will provide a.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the means of the present invention has a warp-knitted blanket whose base structure is knitted with pile yarns, insertion yarns, and chain yarns. A hand-woven, twill-woven, or satin-woven holding fabric portion is formed in all or part of the wiring route of the electric heater wire of the blanket by a pair of holding threads with a gap between it and the ground structure, and this An electric heater wire is inserted into the gap formed by the holding cloth part.

A second technical means of the present invention is that the retaining threads of the retaining cloth portion are made of a material that has less heat shrinkage than the inserting threads and tying threads of the ground weave.

[0007]

[Function] In the electric blanket of the present invention, an electric heater wire is inserted and wired into a gap formed by a holding fabric portion and a base fabric made of a plain weave, twill weave, or satin weave using a pair of holding threads. The wire is held without adhering to the ground tissue, and since the holding thread has the same structure as the insertion thread except for the heater wiring, the structure of the blanket remains unchanged.

[0008]

[Example] An example of the present invention will be described below with reference to FIGS. 1 to 3.
The explanation will be based on. Reference numeral 1 denotes the main body of a warp knitted blanket consisting of a ground structure 2. The ground structure 2 is a known warp-knitted blanket knitted with pile yarns 3, insertion yarns 4, and chain yarns 5. This ground structure 2 has a holding cloth portion 6 formed separately from the ground structure 2 in all or part of a portion that becomes a wiring route for the electric heater wire 8. Therefore, tunnel-shaped gaps 9 and 10 are formed between the holding cloth part 6 and the ground structure 2, through which the electric heater wire 8 is passed. The holding cloth portion 6 is formed of a pair of holding threads 7 in a plain weave. Furthermore, the voids 9 and 10 are divided between the base weave 2 and the base weave 2 for heater wire wiring in a direction parallel to the knitting direction, and for heater wire wiring in a direction perpendicular to the knitting direction. , to match the meandering arrangement of the electric heater wires 8.

In the above embodiment, the electric heater wires 8 are passed through the gaps 10 and 9 formed between the holding cloth section 6 and the ground structure 2 and arranged in a meandering pattern as shown in FIG. The electric heater wire 8 is then held down by the holding cloth section 6.

Furthermore, when wiring the electric heater wire 8, if the ground structure is compressed in a direction perpendicular to the insertion direction of the heater wire as shown in FIG. As a result, the gaps 9 and 10 become tunnel-shaped, and the electric heater wire 8 can be smoothly inserted into the holding cloth portion 6 without getting caught.

FIG. 4 shows a second embodiment of the present invention, which differs from the above embodiment in that the holding cloth portion 6a is formed of twill weave, and is otherwise completely the same as the above embodiment. You can expect the following effects.

FIG. 5 shows a third embodiment of the present invention, which is different from the above embodiment in that the holding cloth portion 6b is made of satin weave, and other than this, it is completely the same as the above embodiment. You can expect good effects.

FIG. 6 shows a fourth embodiment of the present invention, which differs from the above embodiments in that the retaining threads forming the retaining cloth portions 6, 6a, 6b have less heat shrinkage than the insertion threads 4 and the binding threads 5. This is because the holding thread 11 was used. Generally, this type of blanket is manufactured through various heat treatments. Therefore, the holding thread 11
The difference in heat shrinkage of the holding cloth part 6c woven in a plain weave, twill weave, or satin weave causes the holding cloth part 6c to sag, which easily causes the tunnel-shaped gap 9a and the gap 1 to sag.
0a can be formed. Note that specific combinations of materials for the base structure and the holding yarn include a combination of synthetic fibers such as polyamide and polyester, and a combination of natural fibers such as cotton and polyester.

[0014]

[Effects of the Invention] As described above, the present invention makes it possible to arrange and hold heater wires on a warp-knitted blanket without gluing or sewing it, which makes it possible to improve the texture and appearance, and to facilitate production. . Furthermore, it is also possible to prevent damage to the electric heater wire due to expansion and contraction of the ground tissue.
