Abstract

PROBLEM TO BE SOLVED: To prevent the misalignment of a sheet and to prevent the fraying at the end thereof by putting an elastic material sheet of a slender shape to an approximately U shape in section on the end of a supporter, forming a needle hole array at the supporter end near this sheet and enclosing the circumference of the sheet by threads. SOLUTION: The supporter 10 consists of a knitted fabric and its end 11 is formed to the state of easy fraying the knitting yarn without fixing the yarn. While the elastic material sheet 12 made of rubber, etc., of the slender shape is put to the approximately U shape in section on this end 11, the sheet is sewn by the threads with a sewing machine 13. A method to form the needle hole array 14a at the supporter end 11 near the sheet to allow the threads 13 to enclose the circumference of the sheet 12 and further, forming the needle hole array 14b in the sheet 12 and fixing the sheet 12 is used for the way of sewing. Such sewing work is executed simultaneously. The sheet 12 is fixed to the end 11 by the threads 13 in such a manner, by which the misalignment of the sheet 12 during the use is completely prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating an end portion of a medical or sports supporter to be worn on an elbow, a knee, etc., in order to prevent the end portion from fraying.

[0002]

Conventionally, as an end treatment method for preventing fraying of the end of the supporter, an elastic sheet 2 made of rubber or the like at the end of the supporter 1 shown in FIG. There is known a method in which the thread 3 is sewn so as to wrap around the sheet by covering in a letter shape, chain stitching, or overedging.

In this method, since the sheet 2 is covered with the thread 3 only on the outer periphery, while using it,
The sheet 2 may be displaced in the thread 3, the end of the supporter 1 may not be covered, and fray may occur. Further, the sewn portion becomes thicker as the sheet 2 elastically expands, so that the thread 3 may be caught during use and the thread 3 portion may be frayed.

As a means for eliminating such inconvenience,
The present inventor has proposed the processing method shown in FIG. 3 (see Japanese Utility Model Publication No. 63-48258). This processing method is similar to the above, in that the end portion of the supporter 1'is covered with an elastic material sheet 2'of rubber or the like in a substantially U-shaped cross section, and thread 3'is formed by chain stitching or overedging. This is a method of sewing so as to wrap the periphery, and further performing rough zigzag stitching with a thread 4 ′ to fix the seat 2 ′ to the supporter 1 ′.

According to this processing method, the sheet 1'is fixed to the supporter by the zigzag stitch, so that the above-mentioned displacement can be prevented. Further, since the sheet 1'is pressed by the zigzag stitch, the sewn portion is prevented from becoming thick, and the possibility of catching a thread is reduced. But,
To carry out this method, two steps of chain stitching, overlock stitching and zigzag stitching are required, resulting in low production efficiency.

Therefore, the present invention has an object to provide a new end treatment method which can prevent the sheet from being displaced and reduce the possibility of catching a thread, and can be manufactured in one step. It is a thing.

[0007]

According to the present invention, an end portion of a supporter is covered with an elongated elastic material sheet having a substantially U-shaped cross section, and a row of needle holes is formed at the end portion of the supporter near the sheet. The thread is wrapped around the sheet, and the sheet is fixed in one step by using a sewing method for fixing the sheet by forming one needle hole row in the sheet. This is a method for treating the end portion of the supporter.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the edge processing method of the present invention will be specifically described with reference to FIG.

The supporter 10 is made of a knitted material and has an end portion 11
Is in a state where the knitting yarn is not fixed and is easily frayed. While covering the end portion 11 with a sheet 12 made of an elastic material such as an elongated rubber in a substantially U-shaped cross section, the threads 13, ...
Sew with a sewing machine using. In this sewing method, a needle hole row 14a is formed on the supporter end 11 near the seat 12 so that the threads 13, ... Wrap the periphery of the sheet 12, and further, one needle hole row 14b is formed in the seat 12. The seat 12 is fixed with the use of a sewing machine, and these sewing operations are performed simultaneously. Specifically, a double-edge overlock stitch using two needles and four threads is used.

The sewing method is not limited to the above-mentioned method, and any method can be used as long as it can cover the periphery of the sheet and at the same time form one needle hole row in the sheet to pass the thread through the sheet. Can be

[0011]

According to the end treatment method of the present invention, the sheet is covered with the thread, and the row of needle holes is provided in the sheet to fix the sheet directly to the end of the supporter. It is completely prevented that the sheet is displaced. Also, the sheet is pressed by this fixing,
The thin finish also reduces the chance of catching the thread and causing it to fray. Further, since it is completed by only one sewing operation, the productivity is also excellent.

A concern with this processing method is that since the needle hole array is formed in the sheet, when the sheet expands and contracts as the supporter expands and contracts, a crack is generated in the needle hole array portion. For this reason, the processing method of FIG. 3 employs rough zigzag stitches. However, when examined in detail, the sheet is cracked in the needle hole row only due to the expansion and contraction of the needle hole row at a right angle method, and the expansion and contraction in the longitudinal direction of the needle hole row hardly causes the cracks. I understand. Therefore,
In the present invention, since the sheet extends along the end portion of the supporter, attention is paid to the fact that only a longitudinal expansion / contraction deformation occurs, and only one needle hole row of the sheet is provided. It is configured so that it does not line up in the width direction, and the possibility of cracking is minimized.
