multi-material strap

Abstract

Embodiments of the present invention relate to a cinch belt constructed from an outer braided cover having a first thread type and a second thread type. The second wire type is formed of a different material and / or has a different cross-sectional area than the first wire type. In an exemplary embodiment, the cross-sectional area is at least twice the cross-sectional area of ​​the first wire type. Additionally, the second thread type may be a material having stronger elastic properties and / or a greater coefficient of friction than the first thread type. Additionally, in an exemplary embodiment, the cinch strap is constructed with an elastic core that extends the length of the cinch strap.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. non-provisional application No. 13 / 313,800, filed December 7, 2011, which claims priority to provisional application No. 61 / 421,990, filed December 10, 2010 Interest, the disclosures of both applications are hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a cinch belt constructed from an outer braided cover having a first thread type and a second thread type. Background of the invention [0004] Typically, a lacing structure is used to secure a shoe or other article of footwear about a wearer's foot. Typically, tyinglaces, such as laces or shoelaces, are used to bring together two portions of footwear that allow the foot to enter the interior of the footwear. For example, in a traditional athletic shoe, the forefoot opening extends between the medial and lateral sides of the upper portion of the shoe. In...

Problems solved by technology

However, the tie may loosen or completely unravel due to the tie slipping from the knot that was intended to hold the tie in tension

[0005] The wearer of the shoe (eg, a child) may have difficulty tightening the straps sufficiently to prevent this slippage from occurring

However, adding extra tightening force may not prevent the strap from becoming loose or unraveling

Conversely, conventional shoelaces may continue to untangle when the knot of the cinching strap is loosened, because the cross-sectional area of ​​conventional shoelaces may not accommodate the applied force, and conventional straps may not have strap protruding surfaces and External covering of datum surface, protruding surface and datum surface interact to resist slippage
