  • Patent number: 5702403
    Abstract: The invention is directed to an epilating appliance for the removal of human body hairs which is adapted to be held in a user's hand and guided over the sections of the skin to be treated. The epilating appliance includes a cylinder rotary about a center axis, the cylinder periphery being formed by at least one group of relatively fixed blades and at least one group Of relatively movable gripping elements. The blades and the gripping elements of a group are arranged adjacent to each other at least in pairs, and the groups are in successive arrangement on the cylinder when viewed in a direction of rotation of the cylinder. The gripping elements are adapted to approach each other and recede from each other at least in pairs, closing and, respectively, opening a gripping aperture in the process. Adjacent blades combine to form a groove of a width tapering in wedge or funnel shape, with at least one groove end section of reduced groove width being associated with one gripping aperture each.

  • Patent number: 5254124
    Abstract: The invention concerns a hair-plucking head for a motor-driven depilation appliance. The head has a gripping device with at least two diametrically opposed spring-biased gripper jaws which can be pressed against the inside of a hollow cylinder mounted in the casing of the appliance. The jaws operate in conjunction with a control element disposed equiaxially with the cylinder axis. The appliance also has a transmission link between the motor and the cylinder and/or the control element. The jaws are mounted to pivot on pins located inside the cylinder and driven by the control element and a lever assembly.
