Patent ID: 8181317

Claim:
A clamping device, comprising: a W-shaped metallic member to impart resilience for clamping an item; and a casing member having the metallic member embedded therein so that the metallic member is not exposed to exterior, and formed of a polymeric material through injection-molding to prevent corrosion of the metallic member while enhancing an appearance of the clamping device, wherein the metallic member is inserted into the casing member in an unclamped state and a compressed state when injection-molding the casing member, wherein the metallic member comprises a supporting portion having a reinforcing portion bent at both sides thereof, first and second resilient portions integrally formed to the supporting portion, each resilient portion being bifurcated and bent in a U shape from either side of the supporting portion to generate resilience, and first and second extensions integrally extending from the first and second resilient portions, respectively, and wherein the casing member comprises a hinge portion having the supporting portion of the metallic member embedded therein, first and second injection-molded resilient portions integrally injection-molded with the hinge portion and having the first and second resilient portions of the metallic member embedded therein, first and second press portions integrally injection-molded with the first and second resilient portions to act as handles for applying force to unclamp the item around the hinge portion, and first and second clamping portions integrally injection-molded with the first and second press portions to act as a pinching member to clamp the item around the hinge portion.
