Abstract
The present invention describes a novel spring mechanism for a razor. In the razor, the spring member may be disposed in a movable member assembly, portions of which may be used for ejection or pivoting. The spring may be fully encompassed within the assembly and be placed within supporting structures therein. The spring is a loop-shaped element having overlapping end portions with free distal ends. Alternately, the spring member is tear drop shaped loop shape with distal ends that are spaced apart. The spring may be disposed within a first and/or second movable member such as an eject button or a pivot member. A retarding structure on the spring provides a retarding force which is based on the interaction of the retarding structure with a protrusion on an assembly portion to keep the spring orientation intact. The spring is desirably comprised of stainless steel and is a flat wire.
