  • Patent number: 9216516
    Abstract: A razor handle that includes an elongated hollow housing having an opening provided on the front end, a razor head carrier which is slidably mounted in the recess between a first non-shaving position in which the razor head carrier is retracted and completely located inside the recess, a second shaving position, and a sliding mechanism for moving the razor head carrier.

  • Patent number: 8732965
    Abstract: A razor handle including an elongated handle body integral with a flexible yoke for receiving and releasably retaining a shaving cartridge. The razor handle also includes a slide element cooperating with the yoke and connected to the handle body, the slide element being movable relative to the handle body between a rest position, in which the yoke is open and can releasably retain a shaving cartridge received in the yoke, and a release position, in which the yoke is flexed and can receive a shaving cartridge or release a shaving cartridge received in the yoke. The razor handle further includes a spring member to return the slide element from the release position to the rest position, where a stop element prevents the yoke from inadvertently flexing when the slide element is in the rest position.

  • Publication number: 20110252646
    Abstract: A razor handle that includes a housing having a recess, and a razor head carrier which is pivotally mounted in the housing between a first position in which the razor head carrier is retracted inside the recess, and a second position in which the razor head carrier is extended out of the recess. A biasing mechanism biases the razor head carrier in the direction of the shaving position and a retaining mechanism is able to retain the razor head carrier in the non-shaving position. The razor handle includes a damping arrangement that is able to limit the speed of a movement of the razor head carrier from the non-shaving position to the shaving position.

  • Patent number: 8015711
    Abstract: A razor that includes an elongated hollow handle having a front end and a back end. The razor also includes a first razor head and a second razor head, which are both mounted on a support the support being mounted in the handle and slideable along the length of the handle between a first use position and a second use position. The first use position allows the first razor head to project outward from the front end of the handle to allow shaving, while the second razor head is retracted within the handle; the second use position allows the second razor head to project outward from the back end of the handle to allow shaving, while the first razor head is retracted within the handle. The use positions are preferably attained by a manually operable actuator for moving the razor head from one position to the other.

  • Patent number: 7685720
    Abstract: A razor handle having a handle body and a lock/release mechanism that includes two arms, each having a bearing for pivotally connecting a shaving head, the arms extending substantially symmetrically on both sides of a medial axis, the arms being elastically biased opposite to one another 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. The razor handle also includes a plunger which is movable between the two arms, substantially parallel to the medial axis, and a spring biasing the plunger away from the handle body, 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.
