Patent number: 10206439Abstract: 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.Type: GrantFiled: January 24, 2011Date of Patent: February 19, 2019Assignee: KOWA COMPANY, LTD.Inventors: Kazuhiko Matsuo, Hidefumi Koga

Patent number: 9402758Abstract: A supporter includes a small number of members and has a simple fitting method. It can give an intraperitoneal pressure rise effect to a supporter wearer, attain retroflexion suppression, and stabilize the sacroiliac joint. The supporter includes a base material which is formed of a knitted fabric by warp knitting and in which a knitting direction of the knitted fabric is set to be a longitudinal direction. Stretchability in the longitudinal direction is given, while stretchability in a short direction is suppressed. It has a back-supporting section that is a central portion of the base material, projection sections provided by projecting upward both end portions disposed on both sides of the back-supporting section, and curved sections each making the vicinity of the boundary between the back-supporting section and each of the projection sections. Each curved section is curved into a shape of approximate “”.Type: GrantFiled: July 22, 2011Date of Patent: August 2, 2016Assignee: Kowa Company, LTD.Inventors: Kazuhiko Matsuo, Hitoshi Ojima
