Patent number: 8732965Abstract: 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.Type: GrantFiled: October 1, 2008Date of Patent: May 27, 2014Assignee: BIC-Violex SAInventors: Dimitris Efthimiadis, Ioannis Bozikis, Spiros Gratsias

Patent number: 8015711Abstract: 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.Type: GrantFiled: March 15, 2005Date of Patent: September 13, 2011Assignee: BIC-Violex SAInventors: Yiannis Marios Psimadas, Ioannis Bozikis, Dimitris Efthimiadis
