Razor handle

Abstract

A razor handle is disclosed in which a counterweight of a weight and / or a magnet is arranged. The handle may include an upper shell and a lower shell extending between two opposite ends and may be divided into two parts: a base and an arm. The weight and / or the magnet may be arranged within the base and between the upper shell and the lower shell. Therefore, whenever a user places the lower surface of the arm or a surface of the upper shell in a resting position on a horizontal surface when not using the razor, a chuck coupled to the razor handle will not contact the horizontal surface.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Patent Application No. 17 / 228,356, filed on April 12, 2021, which claims the benefit of U.S. Provisional Patent Application No. 63 / 081,114, filed on September 21, 2020, both of which are incorporated herein by reference in their entireties. Background Art

[0003] A handheld razor includes a blade cartridge coupled to a razor handle. In many cases, one or more strips use a lubricant to help achieve a closer shave and / or provide moisturizer to the razor surface or the user's skin. When the user completes his or her shave, the razor is typically placed on a surface where the lubricating strip contacts the surface, which can result in the surface becoming dirty and / or unsanitary exposure to surface bacteria. Summary of the invention

[0004] Embodiments of the inventive concepts disclosed herein relate to a razor including a razor handle and a cartridge. Use of the razor can improve cleanliness of a shaving area and / or user hygiene by preventing the cartridge from contacting a surface on which the razor rests when the user is not using the razor.

[0005] In one aspect, embodiments of the inventive concepts disclosed herein relate to a razor handle including a weight and / or magnet located therein and arranged between an upper surface and a lower surface extending between two opposing ends. In some embodiments, the razor handle may be defined by a base and an arm. With the weight arranged within the base and the razor handle placed in a resting position, the weight within the base section acts as a counterweight to the moment generated by the arm to prevent the arm and a blade cartridge coupled to the arm from contacting a surface when the razor is not in use by a user.

[0006] In another aspect, embodiments of the inventive concepts disclosed herein relate to a razor handle defined by a base and an arm, wherein a weight and / or a magnet is disposed within the base. The center of mass of the base is located at a first distance from a pivot surface, and the center of mass of the arm is located at a second distance from the pivot surface. In some embodiments, the first distance is less than the second distance to prevent the arm and a blade cartridge coupled to the arm from contacting a surface when the razor is not in use by a user.

[0007] In yet another aspect, when a user places the lower surface of the base on a horizontal surface without using the razor handle, a first moment of the base about the horizontal axis is greater than a second moment of the arm about the horizontal axis.

[0008] In yet another aspect, the horizontal length of the base is less than the horizontal length of the arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the following description, several specific details are presented to provide a thorough understanding of the embodiments of the inventive concepts disclosed herein. However, those skilled in the relevant art will recognize 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 cases, well-known implementations or operations are not shown or described in detail to avoid obscuring aspects of the various embodiments of the inventive concepts disclosed herein.

[0020] Figures 1A to 1DA side view, a top view, a bottom view, and a perspective view are shown to illustrate an embodiment of a razor 100 suitable for implementing the inventive concepts described herein. The razor 100 includes a razor handle 110, a cartridge 190 having one or more blades disposed therein, and a cartridge receiving module 192 for coupling the cartridge 190 to the razor handle 110.

[0021] The outer surface of the razor handle 110 includes an upper outer surface 112 and a lower outer surface 114 extending between a first end 116 and a second end 118 to which the cartridge 190 is coupled. The upper outer surface 112 extends upwardly away from the horizontal reference 120 between the first end 116 and the neck 122, and extends downwardly toward the horizontal reference 120 between the neck 122 and the second end 118.

[0022] Lower outer surface 114 extends substantially parallel to and / or along horizontal datum 120 between first end 116 and pivot surface 124 , extends upward away from horizontal datum 120 between pivot surface 124 and neck 122 , and extends downward toward horizontal datum 120 between neck 122 and second end 118 .

[0023] In some embodiments, the second end 118 may include an opening into which the cartridge receiving module 192 may be permanently inserted to facilitate coupling the cartridge 190 to the razor handle 110. In addition, the cartridge receiving module 192 may include a button 194 that, when pushed toward the cartridge 190, ejects or disconnects the cartridge 190 from the razor handle 110.

[0024] Reference now FIG. 2A to FIG. 2D, respectively showing a side view, a top view, a bottom view and a side view of the razor handle 110. The razor handle 110 can be formed by an upper shell 126 and a lower shell 128 and a weight 130 and / or a magnet 132 respectively arranged substantially vertically between the upper shell 126 and the lower shell 128, wherein the internal structure of the upper shell 126 and the internal structure of the lower shell 128 have been adjusted to fix a counterweight including the weight 130 and / or the magnet 132 between these shells. Similarly, the weight 130 and / or the magnet 132 are substantially horizontally arranged between the first end 116 and the pivot surface 124. As embodied herein, the counterweight offsets the weight (or mass) of the razor handle 110 between the counterweight and the second end 118, such that when the user places the razor handle 110 in a horizontal rest position when not in use, neither the second end 118 of the razor handle 110 nor the clamp 190 coupled thereto contacts the surface 162 (as shown below), and when the user magnetically places the razor handle 110 in a vertical rest position when not in use, neither the second end 118 of the razor handle 110 nor the clamp 190 coupled thereto contacts the vertical surface 208 (as shown below).

[0025] Using an alternative reference frame, the weight 130 and / or magnet 132 are respectively disposed substantially vertically between the upper outer surface 112 and the lower outer surface 114, wherein the internal structure between the upper outer surface 112 and the lower outer surface 114 has been adjusted to secure the weight 130 and / or magnet 132 between these surfaces.

[0026] In some embodiments, the weight 130 and the magnet 132 can be separate components. In some embodiments, the weight 130 and the magnet 132 can be integrated into one component and / or manufactured as one component. As discussed in detail below, the weight 130 and / or the magnet 132 can be used to press the base 134 and / or serve as a counterweight for the arm 136, so that the moment of the base 134 (which includes the weight 130 and / or the magnet 132) exceeds the opposite moment of the arm 136. If the chuck 190 is connected to the razor handle 110, the weight 130 and / or the magnet 132 can be used to press the base 134 and / or serve as a counterweight for the arm 136 and the chuck 190, so that the moment of the base 134 exceeds the opposite moment of the arm 136 and the chuck 190.

[0027] The upper shell 126 and the lower shell 128 extend respectively between the first end 116 and the second end 118. The outer surface of the upper shell 126 may include continuous sections, including but not limited to the first upper section 126a, the second upper section 126b and the third upper section 126c; similarly, the outer surface of the lower shell 128 may include continuous sections, including but not limited to the first lower section 128a, the second lower section 128b and the third lower section 128c.

[0028] The first upper section 126a extends upwardly away from the first end 116 at an angle measured relative to the horizontal reference 120. The second upper section 126b extends upwardly away from the first upper section 126a at a smaller angle measured relative to the horizontal reference 120 until reaching the neck 122. The third upper section 126c extends downwardly away from the second upper section 126b and toward the horizontal reference 120 until reaching the second end 118.

[0029] The first lower segment 128a extends away from the first end 116 substantially parallel to the horizontal reference 120 until reaching the pivot surface 124. The second lower segment 128b extends upward from the pivot surface 124 and generally toward the second upper segment 126b. The third lower segment 128c extends downward away from the second lower segment 128b and toward the horizontal reference 120.

[0030] Reference now FIG. 3A to FIG. 3C , showing a side view, a top view, and a bottom view of a razor handle 110, respectively. As shown, the razor handle 110 can be defined by a base 134 and an arm 136, or divided into a base 134 or an arm 136. The base 134 includes a weight 130 and / or a magnet 132 (neither shown), and can be a portion of the razor handle 110 between a first end 116 and a vertical reference 138, wherein the vertical reference 138 extends through the pivot surface 124 and is substantially perpendicular to the horizontal reference 120. The arm 136 can be a portion of the razor handle 110 between the vertical reference 138 and the second end 118 (i.e., a portion of the razor handle 110 that does not include the base 134).

[0031] The length 140 of the base 134 may be the horizontal distance between the pivot axis 142 (about which the pivot surface 124 pivots) and the first end 116, and the moment arm 144 of the base 134 may be the horizontal distance between the pivot axis 142 and the center of mass 146 of the base 134. Likewise, the length 148 of the arm 136 may be the horizontal distance between the pivot axis 142 and the second end 118, and the moment arm 150 of the arm 136 may be the horizontal distance between the pivot axis 142 and the second end 118, and the moment arm 150 of the arm 136 may be the horizontal distance between the pivot axis 142 and the center of mass 152 of the arm 136. As shown, the length 140 is less than the length 148, and the moment arm 144 is less than the moment arm 150.

[0032] Height 154 of second end 118 above horizontal reference 120 may be a vertical distance between horizontal reference 120 and a bottom of second end 118 measured along a vertical axis (not shown) extending perpendicularly away from horizontal reference 120 and through the bottom of second end 118 .

[0033] refer to Figure 3D, showing a side view of the razor 100. The cartridge 190 is coupled to the razor handle 110. The moment arm 156 may be the horizontal distance between the pivot axis 142 (about which the pivot surface 124 pivots) and the center of mass 196 of the cartridge 190. As shown, Figure 3A Moment arm 150 is shown to be less than moment arm 156. Height 160 of clamp 190 above horizontal datum 120 may be the vertical distance between horizontal datum 120 and point 198 of clamp 190, which is the closest point of clamp 190 to horizontal datum 120 as measured along a vertical axis (not shown) extending perpendicularly away from horizontal datum 120 and extending through point 198 and parallel to vertical datum 138.

[0034] Reference now FIG. 4A to FIG. 4C , shows a side view of a razor handle 110. Figure 4A , when not in use, the razor handle 110 has been placed in a horizontal resting position on a surface 162, such as, but not limited to, a horizontal bathroom counter located next to a sink. The distributed mass or weight of the base 134 is represented by a concentrated force 164 applied to the center of mass 146, creating a clockwise moment 166 about the pivot surface 124; similarly, the distributed mass or weight of the arm 136 is represented by a concentrated force 168 applied to the center of mass 152, creating a counterclockwise moment 170 about the pivot surface 124. As embodied herein, when the razor handle 110 is rested in its horizontal resting position on the surface 162, the clockwise moment 166 exceeds the counterclockwise moment 170.

[0035] exist Figure 4B , the finger has applied a downward force on the arm 136 to generate a counterclockwise moment 172, which, when added to the counterclockwise moment 170, generates a total counterclockwise moment 174 that exceeds the clockwise moment 166. This causes the razor handle 110 to pivot 176 counterclockwise about the pivot surface 124 until the second end 118 contacts the surface 162 and the first end 116 rises above the surface 162, as shown.

[0036] exist Figure 4C , the fingers have released the downward force on the arm 136 to release the counterclockwise moment 172. This causes the razor handle 110 to pivot 178 clockwise in a clockwise direction about the pivot surface 124 until the lower outer surface 114 (or first lower section 128a) of the razor handle 110 returns to its horizontal resting position on the surface 162 and the second end 118 returns to its horizontal resting position at a height 154 above the surface 162.

[0037] Reference now Figure 4D and Figure 4E , showing a side view of the razor 100. Figure 4DIn FIG. 1 , the razor handle 110 with the cartridge 190 coupled thereto has been placed in a horizontal resting position. In addition to the clockwise moment 166 and the counterclockwise moment 170, the distributed weight of the cartridge 190, represented by the concentrated force 172 applied to the center of mass 196, generates a counterclockwise moment 180 about the pivot surface 124. When the razor handle 110 is resting in its horizontal resting position on the surface 162, even with the addition of the counterclockwise moment 180, the sum of the counterclockwise moments 170 and 180 does not exceed the clockwise moment 166.

[0038] exist Figure 4E , the finger has applied a downward force on the arm 136 to generate a counterclockwise moment 184, and when the counterclockwise moment 184 is added to the counterclockwise moments 170 and 180, the total counterclockwise moment 174 generated exceeds the clockwise moment 166. This causes the razor handle 110 to pivot 176 counterclockwise about the pivot surface 124 until the point 198 of the collet 190 contacts the surface 162 and the first end 116 rises above the surface 162, as shown.

[0039] Reference now Figure 5A and Figure 5B , two examples of prior art razor retainer systems are shown. Figure 5A In the embodiment, the razor holder system 200 includes a razor handle 202 and a cartridge 204, and when the user is not using the razor 200, a razor holder 206 securely mounted to a vertical surface 208 holds the razor handle 202 and the cartridge 204 in place. Figure 5B In the embodiment of the present invention, the razor holder system 210 includes a razor handle 212 and a cartridge 214. When the razor 210 is not in use by a user, the razor handle 212 and the cartridge 214 are held in place by a razor holder 216 that rests on the horizontal surface 162.

[0040] Reference now FIG. 5C to FIG. 5E , showing a side view, a lower perspective view, and an upper perspective view of a razor holder system 220. The razor holder 222 includes an upper housing 224 and a lower housing 226, respectively, and a magnet 228 disposed therebetween. In some embodiments, the upper housing 224 may include an aperture through which the magnet 228 may extend upward from the lower housing 226.

[0041] Reference now Fig. 5F and Figure 5G, showing a side view, a lower perspective view, and an upper perspective view of a razor holder system 220. The razor holder 222 includes an upper housing 224 and a lower housing 226, respectively, and a magnet 228 disposed therebetween. In some embodiments, the upper housing 224 may include an aperture through which the magnet 228 may extend upward from the lower housing 226. In some embodiments, the razor holder 222 may include an adhesive tape 230 applied to a surface of the lower housing 226 and adapted to secure the razor holder 222 to a surface, such as, but not limited to, a vertical surface 208. When the user is not using the razor 100, the magnet 130 disposed or embedded in the razor 100 may be magnetically engaged with the magnet 228 of the razor holder 222 secured to the vertical surface 208, so that the razor 100 may be magnetically maintained in a resting and / or placement position substantially parallel to the vertical surface 208.

[0042] It is to be understood that the aspects, features and advantages apparent from the foregoing have been effectively implemented, and since certain changes may be made in the disclosed embodiments of the invention without departing from the spirit and scope of the invention, all matter contained herein is to be interpreted as illustrative and not restrictive.
