Abstract

A razor and trimmer combination assembly includes an elongated handle, a razor blade, a trimmer and a motor. The razor blade is disposed at or adjacent a first end of the handle. The trimmer mounts on the handle and includes a moving blade. The motor drives the moving blade.

Claims (14)

1. A grooming tool comprising:

an elongated handle having a length, the handle curving toward a forward direction;

a razor blade cartridge generally facing toward the forward direction and comprising one or more elongated razor blades mounted in the cartridge and positioned for direct contact with skin, wherein the cartridge is mounted in a razor mount at or adjacent a first end of the handle, and wherein the razor blade cartridge and the handle are adapted for use as a wet razor;

a trimmer mounted on the handle, the trimmer comprising at least one elongated moving blade facing toward the forward direction having a length generally parallel with a length of said razor blades;

a motor having an output shaft operatively connected to the at least one moving blade for driving the at least one moving blade and imparting vibratory motion on the handle and the blade cartridge; and

an off center weight rotated by the motor and rotating about an axis that is parallel to said output shaft to impart increased vibratory motion on the handle and increased vibratory motion on the elongated razor blades; and

a transmission assembly continuously coupling the motor output shaft to the trimmer, wherein the transmission assembly translates rotational movement of the motor output shaft and the off center weight to reciprocating lateral movement of the at least one moving blade in a direction generally parallel to the length of the one or more elongated razor blades.

2. The grooming tool of claim 1 wherein said off center weight is provided on the motor output shaft for imparting increased vibratory motion on the handle and increased vibratory motion on the elongated razor blades.

3. A grooming tool comprising:

an elongated handle;

a razor blade cartridge comprising one or more elongated razor blades mounted in the cartridge and positioned for direct contact with skin, wherein the cartridge is mounted at or adjacent a first end of the handle, and wherein the razor blade cartridge and the handle are adapted for use as a wet razor;

a trimmer mounted on the handle, the trimmer comprising at least one moving blade;

a motor operatively connected to the at least one moving blade; and

a transmission connected to the motor and the moving blade, wherein the transmission translates rotational movement from the motor into reciprocal movement of the moving blade, wherein the transmission includes a rod and the moving blade attaches to the transmission such that the moving blade is moveable along the rod.
