Abstract
Abstract A connection between a metal wire hook and a cord of synthetic fiber material particularly suitable for connecting nets of crossing cords into frames for chairs, sofas, beds and similar furniture. The metal wire has a bent portion with a free end. The bent portion of the metal wire spans an angle in excess of 180° and has a pair of shanks which define a clearance space therebetween. The cord extends through this clearance space and the portion of the cord in the clearance space is squeezed and has therefore a reduced cross-section. The hooked portion of the metal wire and the squeezed portion of the cord are preferably cast into a sheathing of thermoplastic material.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
154 words
A connection between a metal wire hook and a cord of synthetic fiber material, comprising a metal wire having a plastically deformed bent U-shaped portion with a free end, said bent portion spanning an angle exceeding 180° and having a pair of converging shanks which define a clearance space therebetween; a cord having an unsqueezed cross-sectional area, said cord extending through said clearance space with its free end folded over, the portion of said cord being squeezed so that its cross-sectional area is reduced; said bent portion of said metal wire is U-shaped and said pair of shanks converge, the maximum width of said clearance space in the bent portion being substantially less than the diameter of said unsqueezed cross-sectional area of said cord; at least said bent portion of said metal wire and said squeezed portion and free end of said cord are cast into a sheathing of thermoplastic material and impregnated thereby.
Claim 2
Dependent Claim
