Razor with moveable center of balance
View Patent ↗A handle for a safety razor has an elongated cavity within the handle and a body disposed within the elongated cavity and moveable along the cavity under the influence of gravity between two positions. In a first position the razor has a first center of balance. In the second position the razor has a second center of balance different from the first center of balance. The handle has a damping fluid within the cavity or a resilient member to damp the movement of the body.
1. A safety razor, comprising:
a razor cartridge, and
a handle, the handle having an elongated cavity therein, a solid body disposed within the cavity and moveable therealong under the influence of gravity between a first position and a second position spaced apart from the first position, and means to damp the movement of the body,
wherein the damping means comprises a liquid disposed within the elongated cavity,
wherein in the first position the safety razor defines a first center of balance and in the second position the safety razor defines a second center of balance,
wherein the first center of balance and the second center of balance are different;
wherein movement of the body from the first position to the second position defines a velocity; and
wherein the velocity of the body is attenuated to substantially zero when the body is close to the second position.
2. The safety razor of claim 1 , wherein the body comprises a unitary part.
3. The safety razor of claim 1 , wherein the body comprises a plurality of parts.
4. The safety razor of claim 1 , wherein said elongated cavity is barrel shaped.
5. A handle for a safety razor, comprising:
a hand gripping portion and a head portion adapted for selective mounting of a razor cartridge thereon,
the gripping portion having an elongated cavity therein, a solid body disposed within the cavity and moveable therealong under the influence of gravity between a first position and a second position spaced apart from the first position, and means to damp the movement of the body,
wherein the damping means comprises a liquid disposed within the elongated cavity,
wherein in the first position, the handle defines a first center of balance and in the second position the handle defines a second center of balance, and
wherein the first center of balance and the second center of balance are different;
wherein movement of the body from the first position to the second position defines a velocity; and
wherein the velocity of the body is attenuated to substantially zero when the body is close to the second position.
6. The razor handle of claim 5 , wherein said elongated cavity is barrel shaped.
