Abstract
A hair cutting unit device for the human head includes a movable open-ended casing in which an electrically operated clipper is mounted on guide means for movement. The blades of the clipper are in the open end of the casing. The position of the clipper with respect to the casing will fluctuate so that the cutting blades are moved away from the open end as the unit is moved upwardly on a head from the lower hairline so as to gradually increase the length of hair being left on the head. Rotary drums and threads in the casing are connected to a fixed member in which the head is positioned to effect translation of the clipper relative to the casing in response to movement of the unit upwardly from the lower hairline.
Claims15
A hair cutting device comprising a unit consisting of a casing having an open end surface and an electrically operated clipper having fixed cutting blade end surface arranged adjacent the open end surface of the casing when in a home position so that both end surfaces may be in the same plane, guide means supporting the clipper for guided controlled movement in the casing, a first rotary drum mounted in the casing, a first thread mounted on the first drum and having one end connected to a connector fixable to a fixedly positioned external object, power transmitting means connecting the rotary drum with the clipper to operatively effect displacement of the clipper from the home position relative to the casing in response to rotation of the rotary drum so that rotation of the rotary drum causes the relative position of the clipper with respect to the casing to vary in response to the spacing of the unit from the fixedly positioned external object, and resilient means connecting the casing with the clipper for urging the clipper toward said home position.
