Abstract

A knee joint supporter which can improve the stability of the knee joint, reduce the wearer's fatigue and reduce the load on the patellar tendon includes a first anchor section formed by wrapping one end of a tubular knitted fabric around the wearer's thigh to tighten it with the fabric, a second anchor section formed by wrapping the other end of the fabric around the wearer's lower thigh to tighten it with the fabric, and a substantially U-shaped knitted supporting section joined to the first anchor section, covering the wearer's patella region and thus supporting the wearer's patella. In the circumferential direction of the fabric, the stretch resistance of the two anchor parts are larger than the stretch resistance of a base fabric section. In the length width direction of the fabric, the stretch resistance of the supporting section is larger than the stretch resistance of the base fabric section.

First claim

The invention claimed is:

1. A knee joint supporter constructed from a tubular knitted fabric that is knitted by circular knitting, and adapted to come into close contact with a body surface of a wearer, thereby assisting a knee joint by improving the stability thereof, the knee joint supporter comprising:
a first anchor section which is arranged around an upper end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a thigh of the wearer;
a second anchor section which is arranged around a lower end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a lower leg of the wearer;
a base fabric section having stretching properties and that is arranged in an area between the first anchor section and the second anchor section of the tubular knitted fabric; and
a supporting section which is arranged in an approximate U-shape such that a first end of the U-shaped supporting section is connected to a lower end of the first anchor section and a second end of the U-shaped supporting section is connected to a different part of the first anchor section and supports the patella of the wearer,
wherein stretch resistances of the first anchor section and the second anchor section in a circumferential direction of the tubular knitted fabric are larger than a stretch resistance of the base fabric section in the circumferential direction of the tubular knitted fabric, and
a stretch resistance of the supporting section in a length direction of the tubular knitted fabric is larger than the stretch resistance of the base fabric section in the length direction of the tubular knitted fabric.

2. The knee joint supporter according to claim 1 , wherein the supporting section which is arranged in the approximate U-shape is configured to surround the patella of the wearer such that a lower portion of the U-shaped supporting section is configured to be disposed below a bottom section of the patella, a first side of the U-shaped supporting section is configured to be disposed on a first side of the patella, and a second side of the U-shaped supporting section is configured to be disposed on a second side of the patella.
