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.

DETAILED DESCRIPTION
[0018] In the following description, several specific details are presented to provide a thorough understanding of embodiments of the inventive concepts disclosed herein. One skilled in the relevant art will recognize, however, that the inventive concepts disclosed herein can be practiced without one or more of the specific details or in combination with other components. In other instances, well-known implementations or operations are not shown or described in detail to avoid obscuring aspects of various embodiments of the inventive concepts disclosed herein.
[0019]
[0020] The external surface of razor handle 110 includes upper external surface 112 and lower external surface 114 extending between first end 116 and second end 118 to which cartridge 190 is coupled. Upper external surface 112 extends upwardly away from horizontal reference 120 between first end 116 and neck 122 and downwardly towards horizontal reference 120 between neck 122 and second end 118.
[0021] Lower external surface 114 extends substantially parallel to and/or along horizontal reference 120 between first end 116 and pivot surface 124, upwardly away from horizontal reference 120 between pivot surface 124 and neck 122, and downwardly towards horizontal reference 120 between neck 122 and second end 118.
[0022] In some embodiments, second end 118 may include opening into which cartridge receiving module 192 may be permanently inserted to facilitate the coupling of cartridge 190 to razor handle 110. In addition, cartridge receiving module 192 may include button 194 that, when pushed towards cartridge 190, ejects or decouples cartridge 190 from razor handle 110.
[0023] Referring now to
[0024] Using an alternative frame of reference, weight 130 and/or magnet 132 are disposed substantially vertically between upper and lower external surfaces 112 and 114, respectively, wherein the internal structure in between upper and lower external surfaces 112 and 114 has been adapted to secure weight 130 and/or magnet 132 in between these surfaces.
[0025] In some embodiments, weight 130 and magnet 132 may be separate components. In some embodiments, weight 130 and magnet 132 may be integrated into and/or manufactured as one component. As discussed in detail below, weight 130 and/or magnet 132 may be employed to hold down base 134 and/or as a counterbalance to arm 136 so that a moment of base 134 (which includes weight 130 and/or magnet 132) exceeds an opposing moment of arm 136. If cartridge 190 is coupled to razor handle 110, weight 130 and/or magnet 132 may be employed to hold down base 134 and/or as a counterbalance to arm 136 and cartridge 190 so the moment base 134 exceeds opposing moments of arm 136 and cartridge 190.
[0026] Upper and lower enclosures 126 and 128, respectively, extend between first end 116 and second end 118. The external surface of upper enclosure 126 may include contiguous sections including, but not limited to, first upper section 126a, second upper section 126b, and third upper section 126c; likewise, the external surface of lower enclosure 128 may include continuous sections including, but not limited to, first lower section 128a, second lower section 128b, and third lower section 128c.
[0027] First upper section 126a extends upwardly away from first end 116 at angle measured from horizontal reference 120. Second upper section 126b extends upwardly away from first upper section 126a at a lesser angle measured from horizontal reference 120 until reaching neck 122. Third upper section 126c extends downwardly away from second upper section 126b and towards horizontal reference 120 until reaching second end 118.
[0028] First lower section 128a extends away from first end 116 and substantially parallel to horizontal reference 120 until reaching pivot surface 124. Second lower section 128b extends upwardly from pivot surface 124 and generally towards second upper section 126b. Third lower section 128c extends downwardly away from second lower section 128b and towards horizontal reference 120.
[0029] Referring now to
[0030] Length 140 of base 134 may be the horizontal distance between pivot axis 142 (about which pivot surface 124 pivots) and first end 116, and moment arm 144 of base 134 may be the horizontal distance between pivot axis 142 and center of mass 146 of base 134. Likewise, length 148 of arm 136 may be the horizontal distance between pivot axis 142 and second end 118, and moment arm 150 of arm 136 may be the horizontal distance between pivot axis 142 and center of mass 152 of arm 136. As shown, length 140 is less than length 148 and moment arm 144 is less than moment arm 150.
[0031] Height 154 of second end 118 above horizontal reference 120 may be the vertical distance between horizontal reference 120 and the bottom of second end 118 as measured along a vertical axis (not shown) extending perpendicularly away from horizontal reference 120 and through the bottom of the second end 118.
