DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0039] The present disclosure will now be described more fully hereinafter with reference to exemplary embodiments thereof. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in the specification, and in the appended claims, the singular forms a, an, the, include plural variations unless the context clearly dictates otherwise.
[0040] A guard for a hair removal device as disclosed herein may be utilized with any type of hair removal device having a blade. For example, the guard may be utilized with a hair trimming apparatus such as that disclosed in U.S. patent application Ser. No. 15/932,888, which is incorporated by reference in its entirety. For example,
[0041] In further embodiments, the guard 202 as disclosed herein may generally include, for example, opposing first and second lateral end members each defining a lateral surface extending between first and second lateral ends; at least one longitudinally-extending member arranged between the opposing first and second lateral end members so that the opposing first and second lateral end members are substantially parallel to one another; and a retaining element arranged on the opposing first and second lateral end members or the at least one longitudinally-extending member to removably retain the guard about a portion of a blade of the hair removal device.
[0042] A width of the longitudinally-extending central member 206 may be determined by an overall width of the corresponding blade assembly 204. For example, where the hair removal device is a double-edge electric shaver comprising a front fixed blade 208 with two outer edges and a moving rear blade 210 with two cutting edges 212, the guard 202 is centered between and extending outwardly toward the cutting edges 212, to outer walls 214 of the longitudinally-extending central member 206.
[0043] As illustrated in
[0044] The guard 200 may generally be composed of a generally rigid, but durable, material that is configured to be removable from about the portion of the blade of the hair removal device. For example, the guard 200 may be composed of a polymer, a metal, a wood, a ceramic, a composite of more than one material, a combination thereof, and the like. In this manner, when the hair removal device 200 including the guard 202 is moved along or across a contact surface (e.g., a user's skin 201) such that the hair removal device 200 including the guard 202 is in direct contact with the contact surface, the guard 202 pushes the contact surface (e.g., the outer surface of the skin 201) away from the blades 208, 210 of the hair removal device 200, so that the hair is positioned to be cut by the hair removal device 200, but the skin is not snagged or otherwise trapped, pinched, and/or cut by the blades 208, 210. As shown in
[0045]
[0046]
[0047] Further, the at least one longitudinally-extending member may comprise first and second longitudinally-extending side members 414, 416 arranged between the opposing first and second lateral end members 402, 404 and on either side of the longitudinally-extending central member 412 such that the first longitudinally-extending side member 414 is arranged between the first lateral ends 408 of the first lateral end member 402 and the second lateral end member 404 and the second longitudinally-extending side member 416 is arranged between the second lateral ends 410 of the first lateral end member 402 and the second lateral end member 404. In some embodiments, the longitudinally-extending central member 412 may define a longitudinal surface 418 that is substantially coplanar with the lateral surfaces 406 of the first and second lateral end members 402, 404. In other embodiments, the longitudinally-extending central member 412 may define a longitudinal surface 418 that is offset from the lateral surfaces 406 of the first and second lateral end members 402, 404, such that the longitudinal surface 418 and the lateral surfaces 406 are substantially non-coplanar. To this end, substantially non-coplanar can indicate that the longitudinal surface 418 is above or below a plane defined by the lateral surfaces 406 by at least 0.2 mm, at least 0.5 mm, or at least 1 mm. In such embodiments, the longitudinal surface 418 and the lateral surfaces 406 may be non-coplanar in that the longitudinal surface 418 is above or below a plane defined by the lateral surfaces 406 by about 0.5 mm to about 4 mm or about 1 mm to about 3 mm. Such non-coplanar configuration may be desirable, for example to more specifically raise the skin away from the blade system at the lateral end members 402, 404 relative to the longitudinally-extending central member 412 in order to more particularly minimizing snagging or pinching of the skin at the lateral ends or corners of the blade system, which is a common area in movable blade systems for such snagging or pinching to occur.
[0048] As illustrated in
[0049] The guard 400 may further comprise a retaining element arranged on the opposing first and second lateral end members 402, 404 to removably retain the guard 400 about a portion of a blade of the hair removal device. The retaining element may be any type of member capable of retaining the guard 400. For example, the retaining element may comprise a flexible tab 422 defined on the rear portion 420, which is arranged to removably engage a corresponding depression in a blade assembly including the blade so as to retain the guard 400 about the portion of the blade. Application of force to the guard 400 may result in removal of the flexible tab 422 from the corresponding depression. In addition to or instead of, the retaining element may include an opening 424 defined on the lateral surface 406 of the opposing first and second lateral end members 402, 404. The opening 424 may be aligned with a corresponding protrusion on the blade assembly. The flexible tab 422 and the opening 424 are thus arranged to retain the guard 400 about the portion of the blade of the hair removal device.

For example, the retaining element may comprise a flexible tab 518 defined on the rear portion 516, which is arranged to removably engage a corresponding depression in a blade assembly including the blade so as to retain the guard 500 about the portion of the blade. Application of force to the guard 500 may result in removal of the flexible tab 518 from the corresponding depression. In addition to, or instead of, the retaining element may comprise an opening 520 defined on the lateral surface 506 of the opposing first and second lateral end members 502, 504. The opening 520 may be aligned with a corresponding protrusion on the blade assembly. The flexible tab 518 and the opening 520 are thus arranged to retain the guard 500 about the portion of the blade of the hair removal device.
[0053]
[0054] Further, the at least one longitudinally-extending member may comprise first and second longitudinally-extending side members 614, 616 arranged between the opposing first and second lateral end members 602, 604 and on either side of the longitudinally-extending central member 612 such that the first longitudinally-extending side member 614 is arranged between the first lateral ends 608 of the first lateral end member 602 and the second lateral end member 604 and the second longitudinally-extending side member 616 is arranged between the second lateral ends 610 of the first lateral end member 602 and the second lateral end member 604. The longitudinally-extending central member 612 may define a longitudinal surface 618 that is substantially co-planar with the lateral surfaces 606 of the first and second lateral end members 602, 604. Substantially co-planar can indicate that the longitudinal surface 618 and the lateral surfaces 606 of the first and second lateral end members 602, 604 are exactly within the same plane, or the longitudinal surface 618 is above or below the lateral surfaces 606 of the first and second lateral end members 602, 604 by no more than 0.5 mm, 0.2 mm, or 0.1 mm.
