Abstract

A razor handle with a counterbalance of a weight and/or magnet disposed therein are disclosed. The handle may include upper and lower enclosures extending between two opposing ends and may be divided into two parts: a base and an arm. The weight and/or magnet may be disposed within the base and between the upper and lower enclosures, and a horizontal length of the base may be less than the horizontal length of the arm. The counterbalance creates a center of mass of the base which is horizontally closer to a pivot surface than a center of mass of the arm. As a result, whenever a lower surface of the arm or a surface of an upper enclosure is placed in a resting position on a horizontal surface when the razor is not employed by a user, a cartridge coupled to the razor handle will not contact the horizontal surface.

Claims (52)

1. A razor handle for shaving a person's skin, comprising:

a first surface;

a second surface opposing the first surface and extending between a first end and an opposing second end, the second end for receiving a razor cartridge; and

a counterbalancing object, where

the first and second surfaces are configured to be placed into either of two horizontal resting positions at the selection of a user,

the first surface is configured with a first flat surface extending more than half of the length of the first surface, a second flat surface extending between the first end and the first flat surface, a third surface extending from the second end, and a first pivot surface formed at an intersection of the first flat surface and the third surface,

the second surface is configured with a third flat surface extending from the first end, a fourth surface extending from the second end for more than half of the length of the second surface, and a second pivot surface formed at an intersection of the third flat surface and the fourth surface,

the first surface extends angularly away from a reference coinciding with and extending through the third flat surface,

the first, second, and third flat surfaces are neither parallel nor perpendicular to each other, and

the counterbalancing object is disposed between at least the first and third flat surfaces, where

a first horizontal resting position is defined as a position in which the first flat surface rests flatly against a horizontal surface, such that

the fourth surface extends downwardly from the second end and then upwardly until reaching the second pivot surface, and

the fourth surface and at least one blade disposed in the razor cartridge are oriented away from a horizontal reference coinciding with and extending through the horizontal surface, and

a second horizontal resting position is defined as a position in which the third flat surface rests flatly against the horizontal surface, such that

the fourth surface extends upwardly from the second end and then downwardly until reaching the second pivot surface, and

the fourth surface and the at least one blade disposed in the razor cartridge are oriented towards the horizontal reference without intersecting the horizontal reference, whereby

 a downward force imparted by the counterbalancing object creates a moment offsetting an opposing moment imparted by at least the razor cartridge and the at least one razor blade when the first flat surface or the third flat surface rests flatly against the horizontal surface in the first horizontal resting position or the second horizontal resting position, respectively,

 the downward force imparted by the counterbalancing object maintains the orientation of the fourth surface and the at least one blade disposed in the razor cartridge when the third flat surface rests flatly against the horizontal surface in the second horizontal resting position, and

 the first end moves upwardly away from the horizontal reference and the second end moves downwardly towards the horizontal reference when the third flat surface rests flatly against the horizontal surface in the second horizontal resting position but for the counterbalancing object and the imparted downward force, thereby

 preventing the razor cartridge from intersecting the horizontal reference in both the first and second horizontal resting positions.

2. The razor handle of claim 1 , wherein

the counterbalancing object is further disposed between at least the second and third flat surfaces, and

one end of the counterbalancing object is wedge-shaped to conform to a wedge-shaped first end formed at an intersection of the second and third flat surfaces.

3. The razor handle of claim 1 , wherein the counterbalancing object is a magnet.

4. The razor handle of claim 1 , wherein the counterbalancing object includes a magnet.

5. The razor handle of claim 1 , wherein

the first and second surfaces extend across a base and an arm, where

a vertical reference of the razor handle, when in the second horizontal resting position, extends upwardly and perpendicularly away from the horizontal reference at the second pivot surface, where

the base, having a first center of mass located a first distance from the vertical reference of the razor handle, extends from the first end to the vertical reference of the razor handle, and

the arm, having a second center of mass located a second distance from the vertical reference of the razor handle, extends from the vertical reference of the razor handle to the second end, such that

the first and second distances are measured along the horizontal reference, and

the first distance is less than the second distance.

6. The razor handle of claim 5 , wherein

the base extends a third distance from the first end to the vertical reference of the razor handle, and

the arm extends a fourth distance from the vertical reference of the razor handle to the second end, such that

the third and fourth distances are measured along the horizontal reference, and

the third distance is less than the fourth distance.

7. The razor handle of claim 1 , wherein

the first and second surfaces extend across a base and an arm, where

a vertical reference of the razor handle, when in the second horizontal resting position, extends upwardly and perpendicularly away from the horizontal reference at the second pivot surface, where

the base extends a first distance from the first end to the vertical reference of the razor handle, and

the arm extends a second distance from the vertical reference of the razor handle to the second end, such that

the first and second distances are measured along the horizontal reference, and

the first distance is less than the second distance.

8. The razor handle of claim 1 , further comprising:

a magnet secured between at least the first and third flat surfaces, where

the first and second surfaces are further configured for user placement of the razor handle into a vertical resting position, where

the vertical resting position is defined as a position in which the third flat surface hangs flatly against a vertical surface of a magnetic holder, such that

the fourth surface extends outwardly from the second end and away from a vertical reference of the magnetic holder, and then inwardly towards the vertical reference of the magnetic holder until reaching the intersection, and

the fourth surface and the at least one blade disposed in the razor cartridge are oriented towards the vertical reference of the magnetic holder without intersecting the vertical reference, whereby

 a magnetic engagement between the magnet and the magnetic holder maintains the orientation of the fourth surface and the at least one blade disposed in the razor cartridge towards the vertical reference of the magnetic holder when the third flat surface hangs flatly against the vertical surface of the magnetic holder in the vertical resting position, thereby

 preventing the razor cartridge from intersecting the vertical reference of the magnetic holder in the vertical resting position.
