JPH05329180A - Production of supporter for articular part - Google Patents

Abstract

PURPOSE:To obtain a supporter for an articular part of which the feel is excellent and which is difficult to fray, by a method wherein a piece of string or a bundle thereof is used and is knitted in a cylindrical shape while being run around the same direction and one area opposed to the inside of the bend of the articular part is closely knitted by densifying knitting compared with the other areas. CONSTITUTION:When the production is adopted to a supporter 10 for knee joint part, for example, the supporter 10 is formed by knitting while a string is being run around in the same direction without changing the number of stitch to one round, ranging from an upper end 11 to a lower end 12. At this time, as knitting is allowed to proceed from the upper end 11 to the lower end 12, the tension of an elastic string mingled is gradually increased and thus the supporter 10 is formed in such a taper shape that the lower end 12 is more slender. In addition, the tension of the string is allowed to change during one round ranging from the upper end 11 to the lower end 12, and one area 13 opposed to the inside of the bend of the joint part is closely knitted by more densifying the knitting compared with the other areas 14. In this way, the area 13 inside is made smaller, thinner and more difficult to stretch, and the whole of the supporter 10 is made slightly in a bent shape.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a joint supporter used for medical or sports purposes.

[0002]

2. Description of the Related Art Supporters used for joints such as knees and elbows are
If it is simply formed into a tubular shape, wrinkles may occur during bending, resulting in poor usability. For this reason, as a joint supporter, a bulge is formed on the outside of the fold in the same way as the heel of the sock, or a plurality of threads are aligned and knitted, and the number of threads is reduced only when the inside of the fold is knitted. A device in which this portion is thin and formed so as to easily shrink (Japanese Utility Model Publication No. 56-46778) has been devised.

[0003]

In the former supporter having the bulged portion, the feel when the joint is straightened is unpleasant, and in manufacturing, the bulged portion is knitted while continuously rotating in the circumferential direction. However, it has to be knitted while reciprocating, resulting in low productivity.

In the latter case, the supporter having the thin portion is easily broken because the yarn is broken around the thin portion, and can be continuously knitted in the circumferential direction in the production, but the thin portion is frequently used. Since the yarn has to be taken in and out, the working speed is reduced and the productivity is low.

An object of the present invention is to improve the above-mentioned inconvenience, and to make it possible to manufacture a joint supporter having a good feeling and free from fraying with high productivity.

[0006]

[Means for Solving the Problems] The present invention uses one or a bundle of yarns and knits them on a cylinder while circling in the same direction, and at this time, a portion that hits the inside of the bending of the joint portion during one revolution. This is a method for manufacturing a joint supporter, which is characterized in that the place is tightly knitted more closely than other parts.

[0007]

In other words, since this supporter is knitted with the stitches on the inside of the fold being narrowed, that is, the amplitude in the length direction of the yarn is reduced, the number of stitches in this portion is small even though it is not reduced. , Thin and hard to stretch. As a result, the entire supporter has a slightly bent shape in a natural state, and the portion on the outside of the bending has a property of being relatively easily stretched, and has a good feel.
In addition, since the thread is not cut in the middle, it does not easily fray. Further, at the time of manufacturing, except that the stitch is changed, the knitting is performed while rotating in one direction as in the case of knitting in a simple tubular shape, so that the manufacturing can be performed at an extremely high speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 shows a joint supporter 10 according to the first embodiment. This supporter 10 is for the knee,
The whole is tubular and knitted from the upper end 11 to the lower end 12 while rotating in the same direction without changing the number of stitches per round. At the time of this knitting, the tension of the elastic yarn to be mixed is gradually increased as the upper end 11 is closer to the lower end 12, and the lower end 12 is tapered. In addition, from the upper end to the lower end, the tension of the thread is changed during one turn, and the portion 13 that hits the inside of the bent portion of the joint is tightly knitted tightly from the other portions 14. The place 13 is small, thin, and difficult to stretch, and the entire supporter 10 has a slightly bent shape.

FIG. 2 shows a joint supporter 20 according to the second embodiment. This supporter 20 is also for knees and, like the supporter 10, is knitted in a tubular shape, and the tension of the elastic yarn is increased toward the lower end 22 from the upper end 21 to form a taper shape. Also, at the central portion in the length direction other than the portions near the upper end and the lower end, the stitches are changed during one lap, and the portion 23 that hits the inner side of bending the joint is tighter knitted than the other portions 24. .. This supporter 20 is also the supporter 1 described above.
Similar to 0, the entire shape is slightly curved.

[0011]

As described above, in the joint part supporter according to the manufacturing method of the present invention, the bending inner part of the joint is densely knitted,
Since it is smaller, the entire supporter has a slightly curved shape,
When worn, the feel is good and fatigue is less likely to occur. Further, in particular, in a medical supporter that is used with a metallic bone member attached for joint protection immediately after removing the cast, the fatigue is greatly reduced because of the slightly bent shape.

Further, since the bent outer side portion of the joint is relatively easily stretched, the bending of the joint is lightened, and it is particularly suitable for sports. In addition, since the stretchable part is only on the outside of the joint, the supporter does not twist and misalign even if the joint is bent and stretched repeatedly. For this reason, a pad that is attached to the outside of the joint of the supporter is used for knee supporters such as volleyball. Would be suitable for.

Since this manufacturing method does not cut or add the yarn in the middle of the process, there is no fear of fraying even if the completed supporter is used for a long period of time, and the manufacturing is performed simply by knitting while winding in one direction. Therefore, the work can be carried out at an extremely high speed and high productivity can be obtained.
