Patent ID: 7685720

Claim:
A razor handle having a lock/release mechanism including: two arms, each having a bearing for pivotally connecting to a shaving head, the arms being connected together by a hinge, the arms extending substantially symmetrically on both sides of a medial axis of the lock/release mechanism, the arms being elastically biased away from each other by the hinge and toward a head locking position wherein the bearings are adapted to pivotally bear the shaving head, and the arms being movable toward one another into a head release position wherein the bearings are adapted to release the shaving head; a plunger which is movable between the two arms, substantially parallel to the medial axis; and a spring biasing the plunger away from a handle body of the razor handle, such that the plunger is adapted to cooperate with a cam surface belonging to the shaving head for biasing the shaving head toward a rest position, wherein the lock/release mechanism further includes an arm pusher which is movable substantially parallel to the medial axis and which is biased toward the handle body by the spring, the arm pusher cooperating with the two arms by camming action for biasing the arms toward the head locking position.
