Dry razor unit - has two outer parallel heads rocking with parallelogram linkage and middle head inclined by extra link

摘要

The dry razor appts includes a drive unit within a housing and at least two parallel shaving heads (upper and lower) which can rock inwards and outwards relative to each other. Between them, and parallel to them, is a further shaving head which can pivot about a fixed axis. The axis is formed at the intersection of two planes. One of the planes is the tangential plane to the outer contour to the two outside shaving heads and the second plane is parallel to the axis of movement of these heads, midway between the intersections of the heads with the common tangent. The outer heads rock with a parallelogram linkage, a further link controlling the inclination of the middle head. ADVANTAGE - Improved contact with skin contour for a closer shave, especially for long hairs.
