Stitchless reinforced corner structure for cloth
First Claim
1. A reinforced corner structure for cloth comprising:
- a foldable interlining member made of tough plastic material and integrally formed by injection, comprising a pair of folding lines separately provided on a surface of said interlining member dividing said interlining member into three regions, a middle region, a left region and a right region, wherein each of said left and middle regions has an annular opening provided in an upper portion, corresponding to each other, and said left and right regions can be folded over said middle region so as to form a consolidated truncated triangle-shaped interlining member with a clearance defined between said regions for allowing a cloth corner to be adjusted therein before being pressed together therewith;
whereby, a strong and durable stitchless reinforced corner structure can be achieved for evenly supporting the tensile strength of the cloth corner.

Abstract
A stitchless reinforced corner structure for cloth includes a foldable interlining member made of tough plastic material and integrally formed by injection, a pair of folding lines formed on a surface of the interlining member defining a middle region, a left region and a right region, a pair of annular openings respectively provided in an upper portion of the middle region and in an upper portion of the left region, a pair of stubs provided at a lower portion of the middle region, and orifices corresponding to the stubs formed respectively on the left and right region, so that, when the left and right region are folded over the middle region, the orifices and the stubs are closely engaged with each other so as to have a cloth corner tightly secured therein without the need for stitching.
