Safety razor having pivotable blade unit
First Claim
1. A safety razor comprising a handle having a handle axis and a blade unit having at least one blade, the blade unit being connected to the handle for a pivotal movement relative thereto about a perpendicular pivot axis substantially perpendicular to the handle axis and the at least one blade for following the skin contours of a user during shaving, the blade unit having a rest position towards which the blade unit is biased by a return force when pivoted about the perpendicular pivot axis away from the rest position, one of the handle and the blade unit having a concave portion formed on its surface, the safety razor further comprising:
- (a) a relative movement transfer member formed between the handle and the blade unit for transferring a relative movement between the handle and the blade unit caused by the pivotal movement, and(b) a return force generating member formed in the concave portion for generating a return force for the blade unit in response to the relative movement transfer member,wherein the return force generating member includes (i) a holding structure for holding a part of the relative movement transfer member, and (ii) an elastic member connected to the holding structure for generating the return force in response to the relative movement transfer member, wherein the relative movement transfer member has a movable axis which moves in response to the relative movement between the handle and the blade unit while being kept parallel to the perpendicular pivot axis.

Abstract
A safety razor includes a handle and a blade unit having at least one blade. The blade unit is connected to the handle for a pivotal movement relative thereto. One of the handle and the blade unit has a concave portion formed on its surface. A relative movement transfer member is formed between the handle and the blade unit for transferring a relative movement between the handle and the blade unit caused by the pivotal movement. A return force generating member is formed in the concave portion for generating a return force for the blade unit in response to the relative movement transfer member. The return force generating member includes a holding structure for holding a part of the relative movement transfer member, and an elastic member connected to the holding structure for generating the return force in response to the relative movement transfer member.
