  • Patent number: 10206439
    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.

  • Patent number: 9579229
    Abstract: A hand joint supporter which can reduce the load on hand joints includes a first anchor section for tightening the wearer's forearm with a tubular knitted fabric, a second anchor section for tightening the palm and back of the wearer's hand with the fabric and a hole anchor section formed as a roughly circular through-hole in the vicinity of the second anchor section. A supporting section extends lengthwise in the fabric across the part covering the caprometacarpal joint and is joined to the first anchor section and the hole anchor section so as to support the wearer's hand joints. Stretch resistance, in the circumferential direction of the fabric of the first anchor part is larger than that of a base fabric section, and stretch resistance, in the length width direction of the fabric, of the supporting section is larger than that of the base fabric section.

  • Patent number: 9526651
    Abstract: A lower leg supporter supports a gastrocnemius muscle from upper, lower, left, and right sides without interfering with movement of an Achilles tendon and which can suppress excessive vibration or deformation of such muscle to reduce a wearer's fatigue. The lower leg supporter includes a first anchor section that secures a tubular knitted fabric to a below-knee part, a second anchor section that secures the tubular knitted fabric to an above-ankle part, and an X-shaped gastrocnemius muscle support section located at a joining part of such muscle and an Achilles tendon on the back surface side of the tubular knitted fabric. Two ends of the X-shaped knitted fabric are joined to the first anchor section to support the gastrocnemius muscle. The other two ends of the X-shaped knitted fabric are joined to the second anchor section, and extend to both edges of the Achilles tendon.

  • Patent number: 9526279
    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.

  • Patent number: 9192200
    Abstract: A foot joint supporter includes a first anchor section for tightening the wearer's lower leg with a tubular knitted fabric, a second anchor section for tightening the wearer's instep and sole with the fabric, and a knitted figure eight section between the first anchor section and the second anchor section, being composed of a foot section and a body section and supporting the wearer's talocrural joint. The foot section includes an instep section covering the wearer's instep and a sole section covering the wearer's sole. A stretch resistance, in the length width direction of the tubular knitted fabric, of the sole section is larger than is the stretch resistance, in the length width direction of the tubular knitted fabric, of the instep section.

  • Publication number: 20120284902
    Abstract: Socks include a tiptoe section, a heel section, a body section excluding a flexible section, and a foot section excluding the tiptoe section and the heel section, provided with a figure eight section supporting the wearer's talocrural joint. A holding section in the figure eight section is joined at one end to the tiptoe section and at the other end to the flexible section and extends toward the front side of the fabric. A supporting section that is a part of the knitted fabric in the figure eight section, excluding the holding section is continuous between the holding section and the heel section from the body section to the feet section. The stretch resistance, in the lengthwise direction of the fabric, of the supporting section is larger than the stretch resistance, in the length width direction of the fabric, of the holding section.
