Patent 6854188 was granted and assigned to American Safety Razor Company on February, 2005 by the United States Patent and Trademark Office.
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.
