Abstract

See full text

A razor handle for a removable pivoting razor blade assembly. The razor blade assembly includes cam means for receiving a biasing force and journal bearing means. The razor handle includes movable members having attached journals, which are slidably movable toward and away from each other to permit engagement of the journal bearing means of the razor blade assembly with the journals of the razor handle. The razor handle also includes cam follower means to provide a yieldable biasing force on the cam means of the razor blade assembly and to maintain the movable members in a latched position until the razor blade assembly provides a predetermined force to the cam follower means to release the movable members to an unlatched position in engagement with the razor blade assembly.
