BACKGROUND OF THE INVENTION
The present invention relates to a knee supporter used for treatment and prevention of knee joint diseases and a method for producing the same.
[0002]
[Prior art]
There are various knee supporters for the treatment and prevention of knee diseases. One of them is a body made of elastic and stretchable material that is wrapped around the thigh, knee and lower leg. There is a type in which a fastening belt is attached and the fastening belt is fastened to a predetermined position on the main body to obtain an appropriate supporting force. In order to make it easier to bend the leg with this knee supporter attached, an opening is made in the part corresponding to the popliteal part on the rear side of the main body, but depending on the tightening position of the tightening belt, It may hit or rub against the skin exposed from the opening, resulting in extreme discomfort.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a knee supporter and a method for manufacturing the knee supporter in which the tightening belt does not feel uncomfortable due to contact with the skin exposed from an opening provided in the knee support body.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problems, according to the present invention, in the knee supporter constituted by the knee supporter body and the fastening belt, the knee supporter body has an opening in a portion corresponding to the rear popliteal part , A patch that is thinner than the material constituting the knee supporter body is attached to the opening so that the surface of the popliteal part exposed through the opening can be protected by the patch .
[0005]
According to the manufacturing method of the present invention, a patch that is thinner than the material constituting the knee supporter body and slightly larger than the size of the opening is temporarily fixed to the back side of the opening at the position facing the popliteal portion of the knee supporter body, A spacer made of a material that has the same shape and dimensions and is difficult to be deformed is fitted on the front side of the opening, and the periphery of the opening is joined to the covering cloth.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to embodiments shown in the drawings.
[0007]
FIG. 1 shows a main part of an embodiment of the present invention, in which a is a front view and b is a cross-sectional view. Reference numeral 1 denotes a knee support body, and a substantially circular opening 2 is opened in a portion corresponding to the popliteal portion when the knee supporter is mounted. On the back side of the opening 2, that is, the side in contact with the skin of the main body 1, a batter 3 is fixed around the opening 2 by, for example, sewing. Since the patch 3 is a part that comes into contact with the skin and the fastening belt comes into contact with the surface thereof, it is suitable to use a thin article having good breathability, hygroscopicity, smoothness, little skin irritation, and a small thickness. For example, 100% nylon jersey, tricot and smooth fabric are particularly suitable. A polyester fabric may be used as the outer material. The thickness is preferably 1 mm or less, for example, 0.6 mm.
[0008]
FIG. 2 shows the manufacturing process of the method for attaching the patch of the present invention to the opening. First, as shown in a, a patch 3 slightly larger than the size of the opening 2 is temporarily fixed 4 at, for example, four corners on the back side of the opening 2 of the main body 1. Next, as shown in b, a spacer 5 having the same shape and size as the opening 2 is prepared, and the spacer 5 is fitted on the front side of the opening 2. c shows this state. Next, as shown in d, the spacer 5 is removed after the application cloth 3 and the main body 1 are joined together by sewing 6, for example, at the periphery of the opening 2. The excess portion that protrudes from the periphery of the opening 2 of the patch 3 can be removed. The spacer has a function to prevent the elastic main body and the thin easily deformable patch from being deformed during sewing, and it is a material that does not deform even when heat or mechanical stress is applied and can maintain its shape. Any type is acceptable. For example, plastic can be used. Although the thickness depends on the thickness of the main body, the same thickness as the main body is preferable. For sewing, it is advantageous to use a computer sewing machine in which the periphery of the opening is stored as a pattern. By using the spacer in this way, a soft patch can be fixed to the periphery of the opening without causing any wrinkles.
[0009]
