Abstract
A razor handle head is provided having a one-piece spring extending between and molded integrally with a pair of opposed arms that carry connectors to which a razor cartridge movably (e.g., pivotally) mounts. The single-piece spring has a pair of outer spring sections extending from the arms and a center portion with a cam follower which bears against a cam surface on the cartridge to bias the cartridge as it moves relative to the handle head. The one-piece spring also flexes with the arms during assembly of the cartridge to the handle head.
Claims15
A razor cartridge biasing device for a razor handle, comprising:
- a razor handle head having a pair of opposing arms extending from the handle head, distal portions of the arms comprising connectors to which a razor cartridge can be movably connected;
- a first outer spring section extending from one of the arms towards the other, arm and having an inner end;
- a second outer spring section extending from the other arm toward the first outer spring section and having an inner end;
- and
- a spring center portion having a cam follower and a pair of legs, a proximal end of each of the legs being attached to the cam follower at an angle to the cam follower, and a distal end of each of the legs being attached to the inner end of a respective one of the outer spring sections;
- wherein the spring center portion is substantially U-shaped;
- and
- wherein the cam follower is for contacting a cam surface of the razor cartridge when the razor cartridge is connected to the handle head to bias the razor cartridge with respect to the handle head.

- a spring center portion having a cam follower and a pair of legs, a proximal end of each of the legs being attached to the cam follower at an angle to the cam follower, and a distal end of each of the legs being attached to the inner end of a respective one of the outer spring sections;
- wherein the cam follower is for contacting a cam surface of the razor cartridge when the razor cartridge is connected to the handle head to bias the razor cartridge with respect to the handle head;
- and
- wherein the handle head has a curved opening between the arms to allow the distal portions of the arms to be displaced towards each other.
