Abstract
Abstract A wet razor having a handle, on the front end of which is disposed a razor head that carries a razor blade, is provided. In the region between the razor head and a grasping portion of the handle, there is provided a turning mechanism via which the razor head, with its razor blade, is freely rotatable relative to the grasping portion of the handle about an axis of rotation that is perpendicular to the cutting edge of the razor blade. Associated with the turning mechanism 5 is a spring-type resetting mechanism via which the razor head, starting from a prescribed starting position and after a limited deflection or travel, can automatically return to the starting position due to spring force.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
221 words
A wet razor having a handle, on a front portion of which is disposed a razor head that carries a razor blade with a cutting edge, said razor further comprising: a rear handle portion; a connecting rod that rigidly interconnects said front and rear portions of said handle; a grasping portion of said handle that is in the form of a sleeve that is disposed about said connecting rod and between said front and rear portions of said handle in such a way as to be freely movable relative thereto and in particular rotatable only relative to said front and rear portions of said handle about an axis of rotation that is perpendicular to said cutting edge of said razor blade; a resetting mechanism disposed within said sleeve for automatically returning said front and rear portions of said handle, and hence said razor head, to a starting position after limited rotation thereof relative to said sleeve, with said resetting mechanism including a helical spring that surrounds said connecting rod, with said spring having two ends, one of which is connected to said sleeve, and the other of which is connected to said front portion of said handle; and a stop arrangement disposed between said sleeve and said front portion of said handle for effecting said limited travel of said razor head.

A wet razor having a handle, on a front portion of which is disposed a razor head that carries a razor blade with a cutting edge, said razor further comprising: a rear handle portion; a connecting rod that rigidly interconnects said front and rear portions of said handle; a grasping portion of said handle that is in the form of a sleeve that is disposed about said connecting rod and between said front and rear portions of said handle in such a way as to be freely movable relative thereto and in particular rotatable only relative to said front and rear portions of said handle about an axis of rotation that is perpendicular to said cutting edge of said razor blade; a resetting mechanism disposed within said sleeve for automatically returning said front and rear portions of said handle, and hence said razor head, to a starting position after limited rotation thereof relative to said sleeve, with said resetting mechanism including a helical spring that surrounds said connecting rod, with said spring having two ends, one of which is connected to said sleeve, and the other of which is connected to said front portion of said handle; and a stop arrangement disposed between said sleeve and said front portion of said handle for effecting said limited travel of said razor head.
Claim 3
Dependent Claim
35 words
A wet razor according to claim 1, in which said stop arrangement limits said travel of said razor head, starting from said starting position, to a maximum of about 30° in either direction of rotation.
Claim 4
Dependent Claim
45 words
A wet razor according to claim 2, in which said stop arrangement includes a recessed portion, in the shape of part of a ring, in said front portion of said handle, and a tab on said sleeve that projects radially inwardly into said recessed portion.
Claim 5
