Abstract

An elbow joint supporter includes a first anchor section formed by wrapping one end of a tubular knitted fabric around the wearer's upper arm, a second anchor section formed by wrapping the other end of the fabric around the wearer's forearm, and a substantially X-shaped knitted supporting section intersecting at the wearer's cubital fossa. Two ends of the X-shaped knitted fabric are joined to the first anchor section and the other two ends of the X-shaped knitted fabric are joined to the second anchor section so as to support the wearer's elbow joint. In the circumferential direction of the fabric, the stretch resistances of the first anchor part and the second anchor part are larger than that of a base fabric section. In the length direction of the fabric, the stretch resistance of the supporting section is larger than that of the base fabric section.

First claim

The invention claimed is:

1. An elbow joint supporter constructed from a tubular knitted fabric that is knitted by circular knitting, and adapted to come into contact with a body surface of a wearer, thereby assisting an elbow joint by improving the stability thereof, the elbow joint supporter comprising:
a first anchor section configured as a knitted fabric which is knitted around a first end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a brachium of the wearer;
a second anchor section configured as a knitted fabric which is knitted around a second end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a forearm of the wearer;
a supporting section includes a front face side which is knitted in an X-shape configuration that is formed of two intersecting portions which covers and is adapted to cross over a cubital fossa of the wearer, and is adapted to support the elbow joint of the wearer by connecting a first two end portions of said supporting section to the first anchor section and connecting a second two end portions of said supporting section to the second anchor section;
a base fabric section which is a knitted fabric surrounded by the first anchor section, the second anchor section, and the supporting section of the tubular knitted fabric; and
an olecranon contact section which is knitted on a rear face side of the tubular knitted fabric and is adapted to contact an olecranon of the wearer;
wherein the base fabric section is a tuck stitch knitted fabric,
the olecranon contact section is a mesh stitch knitted fabric or a bellows knitted fabric,
a stretch resistance of the first anchor section and the second anchor section in a circumferential direction of the tubular knitted fabric is greater than a stretch resistance of the base fabric section in the circumferential direction of the tubular knitted fabric,
a stretch resistance of the supporting section in a length direction of the tubular knitted fabric is greater than a stretch resistance of the base fabric section in the length direction of the tubular knitted fabric,
a first end of the first two end portions of the supporting section connected to the first anchor section at a first position and a second end of the first two end portions of the supporting section connected to the first anchor section at a second position, the first position disposed at a distance from the second position along both a front circumferential direction of the tubular knitted fabric and a rear circumferential direction of the tubular knitted fabric, the first end of the first two end portions and the second end of the first two end portions disposed at a distance from each other along both the front circumferential direction of the tubular knitted fabric and the rear circumferential direction of the tubular knitted fabric;
a first end of the second two end portions of the supporting section connected to the second anchor section at a first position and a second end of the second two end portions of the supporting section connected to the second anchor section at a second position, the first position disposed at a distance from the second position along both the front circumferential direction of the tubular knitted fabric and the rear circumferential direction of the tubular knitted fabric, the first end of the second two end portions and the second end of the second two end portions disposed at a distance from each other along both the front circumferential direction and the rear circumferential direction of the tubular knitted fabric;
the base fabric section is connected to the first anchor section and the second anchor section on the rear face side of the tubular knitted fabric;
the olecranon contact section is surrounded by the base fabric section;
a stretch resistance of the olecranon contact section in the length direction of the tubular knitted fabric is less than the stretch resistance of the base fabric section in the length direction of the tubular knitted fabric; and
the olecranon contact section is configured to absorb forces associated with an expansion and contraction of the skin of the wearer during movement of the elbow joint and prevent a position shift in any direction of the elbow joint supporter.

2. The elbow joint supporter according to claim 1 , wherein the supporting section is a knitted fabric in which a tuck stitch knitted fabric and a plating stitch knitted fabric are used in combination.

3. The elbow joint supporter according to claim 1 , wherein the olecranon contact section is a knitted fabric in which a mesh stitch knitted fabric and a plain stitch knitted fabric which extend in the circumferential direction of the tubular knitted fabric are alternately arranged in parallel.

4. The elbow joint supporter according to claim 1 , wherein a knitted fabric of a boundary of the olecranon contact section is knitted by overlapping an upper thread which is used in the base fabric section and an upper thread which is used in the olecranon contact section and using the upper thread of the base fabric section and the upper thread of the olecranon contact section along with an under thread which is used in both the base fabric section and the olecranon contact section.

5. The elbow joint supporter according to claim 1 , further comprising:
reinforcing sections which are knitted to extend in the length direction of the tubular knitted fabric at first and second side portions on the front face side of the tubular knitted fabric and connected to the first anchor section and the second anchor section, thereby reinforcing the supporting section.

6. An elbow joint supporter constructed from a tubular knitted fabric that is knitted by circular knitting, and adapted to come into contact with a body surface of a wearer, thereby assisting an elbow joint by improving the stability thereof, the elbow joint supporter comprising:
a first anchor section configured as a knitted fabric which is knitted around a first end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a brachium of the wearer;
a second anchor section configured as a knitted fabric which is knitted around a second end of the tubular knitted fabric and adapted to allow the tubular knitted fabric to be tightened on a forearm of the wearer;
a supporting section includes a front face side which is knitted in an X-shape configuration that is formed of two intersecting portions which covers and is adapted to cross over a cubital fossa of the wearer, and is adapted to support the elbow joint of the wearer by connecting a first two end portions of said supporting section to the first anchor section and connecting a second two end portions of said supporting section to the second anchor section;
a base fabric section which is a knitted fabric surrounded by the first anchor section, the second anchor section, and the supporting section of the tubular knitted fabric; and
an olecranon contact section which is knitted on a rear face side of the tubular knitted fabric and is adapted to contact an olecranon of the wearer;
wherein the base fabric section is a tuck stitch knitted fabric,
the olecranon contact section is a mesh stitch knitted fabric or a bellows knitted fabric,
a stretch resistance of the first anchor section and the second anchor section in a circumferential direction of the tubular knitted fabric is greater than a stretch resistance of the base fabric section in the circumferential direction of the tubular knitted fabric;
a stretch resistance of the supporting section in a length direction of the tubular knitted fabric is greater than a stretch resistance of the base fabric section in the length direction of the tubular knitted fabric;
