RAZOR HANDLE
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.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 63/081,114, filed Sep. 21, 2020, which is
incorporated by reference herein in its entirety. In addition, this
application incorporates by reference U.S. patent application Ser.
No. 29/776,300 herein in its entirety.
BACKGROUND
[0002] Handheld razors include a cartridge of blades coupled to a
razor handle. In many instances, one or more strips employ
lubricant(s) may to help achieve a closer shave and/or provide a
moisturizer to the shaver's or user's skin. When the user is
finished with his or her shave, the razor is often placed on a
surface in a position where the lubricating strips contact the
surface which can result with a messy surface and/or an unhygienic
exposure to surface germs.
SUMMARY
[0003] Embodiments of the inventive concepts disclosed herein are
directed to a razor comprising a razor handle and a cartridge. The
use of this razor may improve the cleanliness of the shaving area
and/or hygiene of a user by preventing the cartridge from
contacting a surface upon which the razor rests when not employed
by the user.
[0004] In one aspect, embodiments of the inventive concepts
disclosed herein are directed to a razor handle comprising a weight
and/or a magnet therein and disposed between upper and lower
surfaces which extend between two opposing ends. In some
embodiments, razor handle may be defined with a base and an arm.
With the weight disposed within the base and the razor handle being
placed in a resting position, the weight within a base sections
acts as a counterbalance to a moment created by the arm to prevent
the arm and cartridge of blades coupled to the arm from contacting
the surface when the razor is not employed by a user.
[0005] In another aspect, embodiments of the inventive concepts
disclosed herein are directed to a razor handle defined with a base
and an arm, wherein a weight and/or a magnet are disposed within
the base. The base has a center of mass located a first distance
from a pivot surface, and the arm has a center of mass located a
second distance from the pivot surface. In some embodiments, the
first distance is less than the second distance to prevent the arm
and cartridge of blades coupled to the arm from contacting the
surface when the razor is not employed by a user.
[0006] In a further aspect, a first moment of the base about a
horizontal axis is greater than a second moment of the arm about
the horizontal axis when a lower surface of the base rests on a
horizontal surface when the razor handle is not employed by a
user.
[0007] In a further aspect, a horizontal length of the base is less
than a horizontal length of the arm.

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] FIGS. 1A through 1D, side, top, bottom, and perspective
views are shown, respectively, to illustrate an embodiment of razor
100 suitable for implementation of the inventive concepts described
herein. Razor 100 includes razor handle 110, cartridge 190 within
which one or more blades are disposed, and cartridge receiving
module 192 for coupling cartridge 190 to razor handle 110.
[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 FIGS. 2A through 2D, side, top, bottom, and
side views of razor handle 110 are illustrated, respectively. Razor
handle 110 may be formed from upper enclosure 126 and lower
enclosure 128, and weight 130 and/or magnet 132 disposed
substantially vertically between upper and lower enclosures 126 and
128, respectively, where the internal structures of upper and lower
enclosures 126 and 128, respectively, have been adapted to secure a
counterbalance comprising a weight 130 and/or magnet 132 in between
these enclosures. Similarly, weight 130 and/or magnet 132 are
disposed substantially horizontally between first end 116 and pivot
surface 124. As embodied herein, the counterbalance counters the
weight (or mass) of razor handle 110 between it and second end 118
so that neither second end 118 nor cartridge 190 coupled to second
of razor handle 110 contacts neither surface 162 (shown below) when
razor handle 110 rests in a horizontal resting position when not
employed by a user nor vertical surface 208 (shown below) when
razor handle 110 magnetically rests in a vertical resting position
when not employed by a user.
[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 FIGS. 3A through 3C, side, top, and bottom
views of 110 razor handle are illustrated, respectively. As shown,
razor handle 110 may be defined by or divided into base 134 and arm
136. Base 134 includes weight 130 and/or magnet 132 (neither shown)
and may be the portion of razor handle 110 in between first end 116
and vertical reference 138 extending through pivot surface 124 and
substantially perpendicularly from horizontal reference 120. Arm
136 may be the portion of razor handle 110 in between vertical
reference 138 and second end 118 (i.e., portion of razor handle 110
that excludes base 134).
[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.
[0032] Referring to FIG. 3D, a side view of razor 100 is
illustrated. Cartridge 190 is coupled to razor handle 110. Moment
arm 156 may be the horizontal distance between pivot axis 142
(about which pivot surface 124 pivots) and center of mass 196 of
cartridge 190. As shown, moment arm 150 as shown in FIG. 3A is less
than moment arm 156. Height 160 of cartridge 190 above horizontal
reference 120 may be the vertical distance between horizontal
reference 120 and point 198 of cartridge 190, the closest point of
cartridge 190 to horizontal reference 120 as measured along a
vertical axis (not shown) extending perpendicularly away from
horizontal reference 120 and through point 198 and parallel to
vertical reference 138.
[0033] Referring now to FIGS. 4A through 4C, side views of razor
handle 110 are illustrated. In FIG. 4A, razor handle 110 has been
placed in a horizontal resting position on surface 162 such as, but
not limited to, a horizontal bathroom counter next to sink when not
in use. The distributed mass or weight of base 134, as represented
by concentrated force 164 being applied to center of mass 146,
creates a clockwise moment 166 about pivot surface 124; similarly,
the distributed mass or weight of arm 136, as represented by
concentrated force 168 being applied to center of mass 152, creates
a counterclockwise moment 170 about pivot surface 124. As embodied
herein, clockwise moment 166 exceeds counterclockwise moment 170
when razor handle 110 rests in its horizontal resting position on
surface 162.
[0034] In FIG. 4B, a finger has applied a downward force on arm 136
to create counterclockwise moment 172 that, when added to
counterclockwise moment 170, creates a total counterclockwise
moment 174 that exceeds clockwise moment 166. This causes razor
handle 110 to pivot counterclockwise 176 about pivot surface 124
until second end 118 contacts surface 162 and first end 116 rises
above surface 162 as shown.
[0035] In FIG. 4C, the finger has released the downward force on
arm 136 to release counterclockwise moment 172. This causes razor
handle 110 to pivot clockwise 178 about pivot surface 124 in a
clockwise direction until lower external surface 114 (or first
lower section 128a) of razor handle 110 returns to its horizontal
resting position on surface 162 and second end 118 returns to its
horizontal resting position at height 154 above surface 162.
[0036] Referring now to FIGS. 4D and 4E, side views of razor 100
are illustrated. In FIG. 4D, razor handle 110 with cartridge 190
coupled has been placed in the horizontal resting position. In
addition to the presence of clockwise moment 166 and
counterclockwise moment 170, the distributed weight of cartridge
190 creates a counterclockwise moment 180 about pivot surface 124,
where the distributed weight of cartridge 190 is represented by
concentrated force 172 being applied to center of mass 196. Even
with the addition of counterclockwise moment 180, the sum of
counterclockwise moments 170 and 180 do not exceed clockwise moment
166 when razor handle 110 rests in its horizontal resting position
on surface 162.
[0037] In FIG. 4E, a finger has applied a downward force on arm 136
to create counterclockwise moment 184 that, when added to
counterclockwise moments 170 and 180, creates a total
counterclockwise moment 174 that exceeds clockwise moment 166. This
causes razor handle 110 to pivot counterclockwise 176 about pivot
surface 124 until point 198 of cartridge 190 contacts surface 162
and first end 116 rises above surface 162 as shown.
[0038] Referring now to FIGS. 5A and 5B, two exemplars of prior art
razor holder systems are illustrated. In FIG. 5A, razor holder
system 200 includes razor handle 202 and cartridge 204 being held
in place by razor holder 206 securely mounted to vertical surface
208 when razor 200 is not employed by a user. In FIG. 5B, razor
holder system 210 includes razor handle 212 and cartridge 214 being
held in place by razor holder 216 resting on horizontal surface 162
when razor 210 is not employed by a user.
[0039] Referring now to FIGS. 5C through 5E, side, lower
perspective, and upper perspective views of razor holder system 220
are illustrated. Razor holder 222 include upper and lower
enclosures 224 and 226, respectively, and magnet 228 disposed in
between them. In some embodiments, upper enclosure 224 may include
an aperture through which magnet 228 may be extend upwardly from
lower enclosure 226.
[0040] Referring now to FIGS. 5F and 5G, side, lower perspective,
and upper perspective views of razor holder system 220 are
illustrated. Razor holder 222 include upper and lower enclosures
224 and 226, respectively, and magnet 228 disposed in between them.
In some embodiments, upper enclosure 224 may include an aperture
through which magnet 228 may be extend upwardly from lower
enclosure 226. In some embodiments, razor holder 222 could include
an adhesive strip 230 applied to a surface of lower enclosure 226
and adapted to affix razor holder 222 to a surface such as, but not
limited to, vertical surface 208. When razor 100 is not employed by
a user, magnet 130 disposed or embedded in razor 100 may
magnetically engage magnet 228 of razor holder 222 affixed to
vertical surface 208, such that razor 100 may be magnetically held
in a resting and/or handing position that is substantially parallel
to vertical surface 208.
[0041] It should be understood that the aspects, features and
advantages made apparent from the foregoing are efficiently
attained and, since certain changes may be made in the disclosed
inventive embodiments without departing from the spirit and scope
of the invention, it is intended that all matter contained herein
shall be interpreted as illustrative and not in a limiting
sense.
