  • Publication number: 20110239475
    Abstract: A razor handle including an elongated handle body that terminates in a flexible yoke for receiving and releasably retaining a shaving cartridge. The razor handle further includes a slide element that cooperates with the yoke and is connected to the handle body, where the slide element is 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). Further, the razor handle includes a spring member to return the slide element from the release position to the rest position. Additionally, the razor handle includes a stop element to prevent the yoke from inadvertently flexing when the slide element is in the rest position.

  • Patent number: 7934320
    Abstract: A razor handle having a front end, a back end opposite the front end, an upper surface, a lower surface opposite the upper surface, and a length in a longitudinal direction defined between the front and back ends. The razor handle includes a head portion and a body portion for hand grasping of the razor handle. A first cross-sectional shape of the upper surface is arcuate and has a radius of curvature that increases along the length of the razor handle, from the back end towards a median location located at approximately half the length of the razor handle, and that decreases along the length of the razor handle, from the median location towards the front end. The first cross-section defined by a plane extends from the back end to the front end and is substantially perpendicular to the upper and lower surfaces.
