Abstract
A safety razor blade unit mounted for pivotal movement relative to a razor handle about a pivot axis substantially perpendicular to a blade mounted in the blade unit. The blade unit is biased to a rest position by a magnetic return force generated by a set of magnetic elements. The set of magnetic elements are so disposed that the return force increases as the pivotal displacement of the blade unit from the rest position increases.
Claims14
A safety razor comprising a handle and a blade unit with a guard, a cap and at least one blade, the blade unit being mounted to the handle for movement relative thereto about a first pivot axis substantially parallel to the at least one blade and a second pivot axis substantially perpendicular to the at least one blade for following the skin contours during shaving, the blade unit having a first rest position relative to the first pivot axis and a second rest position relative to the second pivot axis towards which the blade unit is biased by
- a first return force when pivoted about said first pivot axis away from the first rest position, the first return force comprises a magnetic force generated by a first set of magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit about the first pivot axis substantially parallel to the at least one blade, and the return force increases in magnitude as the blade unit pivots away from the first rest position;
- and
- a second return force when pivoted about said second pivot axis away from the second rest position, the second return force comprises a magnetic force generated by a second set of magnetic elements that are moved relative to each other in response to pivotal movement of the blade unit about the second pivot axis which is distinct from said first pivot axis, and the return force increases in magnitude as the blade unit pivots away from the second rest position.
