TECHNICAL FIELD

[0002] Embodiments of the present invention generally relate to a skin treatment device. More specifically, embodiments of the present invention relate to an abrasive skin treatment device for removing calluses and dead skin,

BACKGROUND

[0003] A callus is a thickened and/or hardened part of the skin, and can often be found on hands and feet. Often, the callus is dead skin. Calluses can appear on feet due to rubbing from poorly fitting shoes or excessive exercise, and can commonly be found on the heel, sides of the toes, or the bail of the foot. Calluses can appear on hands from rubbing and pinching of skin that occurs while lifting heavy objects or from regular weight- lifting, and can commonly be found on the palms right below the fingers.

[0004] There are a variety of known methods of removing calluses, most of these methods involve scraping, shaving, or rubbing the calluses until the dead skin has been removed. Other methods include softening the callus by soaking the callus in warm water or using lotions or creams. Known devices used to remove calluses or dead skin, include pumice stones, foot files, and a variety of abrasive devices. Some of these devices are electrically powered, and include a rotating or vibrating abrasive head.

[0005] The known abrasive devices have several drawbacks. Due to the shape of the abrasive or exfoliating surface, known devices are often unable to adjust to the contours or curvature of the surfaces where calluses generally occur. Accordingly, either the user often has to adjust their grip or move their wrist in order to optimize the angle at which the abrasive or exfoliating surface is contacting the callus or dead skin, or the user has to repeatedly cover the contoured areas several times with the abrasive device to effectively remove the callus or dead skin.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Embodiments of the present invention generally relate to a skin treatment device. More specifically, embodiments of the present invention relate to a pivoting abrasive skin treatment device for removing calluses and dead skin,

[0025] Figure 1 shows an exemplary skin treatment device 10 according to exemplary embodiments of the present invention. As shown in Figure 1 , skin treatment device 10 can include a handle portion 14, a head portion 1 1 , an exfoliating element 12, and a unitary pivoting mechanism 13, Exfoliating element 12 can include an abrasive surface that is suited for removing a callus/hardened skin and the unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot relative to the handle portion 14. Additionally, as shown in Figure 1 , skin treatment device 10 can optionally include switch 18 and a light 15. In operation, a user can hold skin treatment device 10 via handle portion 14 and position exfoliating element 12 against a callus/hardened skin or other target area the user desires to treat, !n use, the user may turn skin treatment device 10 ON via switch 18, thereby activating a motor which drives exfoliating element 12. For example, the motor may cause exfoliating element 12 to move in a reciprocating pattern (e.g., linear, rotational) or in a rotational pattern at a rate sufficient to remove the callus/hardened skin or otherwise treat the target area when the moving exfoliating element 12 is in contact with the target area. As the user treats the callus/hardened skin or other target area, pivoting mechanism 13 may enable relative movement between handle portion 14 and head portion 1 1 to conform and adjust to contours/irregularities of the surface of the target area and the movement of skin treatment device 10 introduced by the user.

[0026] As shown in Figures 1 and 2, skin treatment device 10 includes exfoliating element 12. Exfoliating element 12 includes an abrasive surface and is articulated by skin treatment device 10 so that the motion of exfoliating element 12 against a callus/hardened skin, or other target area, can remove/exfoliate the skin from the target area. Exfoliating element 12 may be articulated by a motor of skin treatment device 10, and may be articulated in any manner. For example, exfoliating element 12 may rotate, move back and forth linearly, move back and forth along an arc, or move in some other reciprocating motion. Further, exfoliating element 12 may to releasabiy coupled so that exfoliating element 12 can be replaced as the abrasive surface becomes worn through use. As shown in Figures 1 -3, exfoliating element 12 may be substantially cylindrical. Additionally, exfoliating element 12 can include different materials and different levels of abrasiveness/coarseness for different applications,

[0027] As shown in Figures 1 and 2, head portion 1 1 secures and positions exfoliating element 12. Head portion 1 1 can be configured to secure and position exfoliating element 12 in any position or configuration that may be convenient and/or ergonomic for the operation of skin treatment device 10, For example, as shown in Figures 1 and 2, head portion 1 1 may include two arms 22 and 23, which can include coupling elements for receiving and coupling exfoliating element 12 there-between. Alternatively, head portion 1 1 can include any configuration to secure and position exfoliating element 12 for any desired orientation and mode of operation. According to certain embodiments of the present invention, exfoliating element 12 can be coupled to head portion 1 1 via coupling elements. Exfoliating element 12 may be fixedly coupled to the head portion 1 1 . Alternatively, the exfoliating element 12 can be rotatably coupled to the head portion 1 1. Exfoliating element 12 may be coupled to head portion 1 1 via any suitable coupling element, such as, e.g., a saddle joint, a ball-and-socket joint, a tension spring, or the like.

[0028] Figures 3a and 3b show exfoliating element 12 and Figures 4a and 4b show exemplary head portion 1 1 coupling elements 40 and 41 according to embodiments of the present invention. As shown in Figures 3a and 3b, exfoliating element 12 may be substantially cylindrical and may include coupling elements 30 and 31 for coupling exfoliating element 12 to head portion 1 1 via coupling elements 40 and 41 . For example, coupling elements 30 and 31 may engage coupling elements 40 and 41 , thereby enabling exfoliating element 12 to be releasably coupled to head portion 1 1 . Alternatively, coupling elements 30 and 31 may engage coupling elements 40 and 41 to be permanently coupled to head portion 1 1 , According to one embodiment, coupling elements 30 and 31 may include features configured to engage complimentary features of coupling elements 40 and 41 on head portion 1 1 . For example, coupling elements 30 and 31 may include spring loaded projections configured to compress and engage recesses of coupling elements 40 and 41 formed in head portion 1 1 , Alternatively, coupling elements 30 and 31 may include recesses configured to receive projections of coupling elements 40 and 41 included on head portion 1 1. Although Figures 3a, 3b, 4a, and 4b show exfoliating element 12 to be substantially cylindrical, coupling elements 30 and 31 to include projections, and coupling elements 40 and 41 to include recesses, exfoliating element 12 and coupling elements 30, 31 , 40, and 41 can take any shape, form, or mechanism that facilitates the desired functionality.

[0029] As noted above, exfoliating element 12 can be removably coupled to head portion 1 1 to enable replacement of exfoliating element 12 and to provide adaptability for different applications. Accordingly, as illustrated in Figure 2, the head portion 1 1 can optionally house including a release mechanism 17 by which to disengage the coupling exfoliating element 12 to head portion 1 1 , thereby releasing exfoliating element 12 from head portion 1 1 . For example, release mechanism 17 may include a release button, which when activated, is configured to disengage coupling elements 30 and 31 from coupling elements 40 and 41 , thereby disengaging exfoliating element 12 from the head portion 1 1 . The release mechanism may be any of the mechanisms known in the art that can be used to disengage exfoliating element 12 from the head portion 1 1 , such as, e.g., a spring- loaded button, snap button, or the like. Additionally, according to embodiments of the present invention, the head portion 1 1 can optionally house a light 15 to illuminate the callus/hardened skin or target area. The light may be beneficial to a user because it can allow them to better view the target area. In a preferred embodiment the light 15 can include a light emitting diode. Additionally, the light 15 can be turned on/off using a switch 18. According to embodiments of the present invention, the switch 16 can be disposed on the handle portion 14. Alternatively, the switch 16 can be disposed on head portion 16 or unitary pivoting mechanism 13.

[0030] According to embodiments of the present invention, the handle portion 14 can be shaped in any shape or size to comfortably fit in a users hand. For example, the handle portion 14 may be cylindrical, cuboidal, ball-shaped, spherical, or the like. Additionally, the handle portion 14 can be shaped in a variety of different sizes for different sized users. Alternatively, in a preferred embodiment, as shown in Figures 1 and 2, the handle portion 14 may be contoured and designed to ergonomicaiiy fit in a users hand to minimize discomfort and fatigue, and to maximize control over the device. For example, as illustrated in Figures 1 and 2, the handle portion 14 can have indentations 20 to accommodate the thumbs of a user, and a wider, oval base 21 to allow the device 10 to securely sit in the palm of a user.

[0031 ] Additionally, the handle portion 14 and/or the head portion 1 1 can house a motor assembly to electrically power the rotational or reciprocating motion of the exfoliating element 12. The motor assembly may include various components such as, e.g., gears, linkages, etc. that enable the motor to drive exfoliating element 12. The motor assembly may be powered by any electrical power, for example, by battery power, by AC power via a plug adapter, etc. The supplied electrical power may be housed anywhere within skin treatment device 10. According to embodiments of the present invention and as illustrated in the Figures, the handle portion 14 can house a switch 16 to turn the motor assembly on/off. Alternatively, switch 16 can be disposed on head portion 1 1 or unitary pivoting mechanism 13.

[0032] According to embodiments of the present invention, skin treatment device 10 preferably includes unitary pivoting mechanism 13, which allows relative movement between handle portion 14 and head portion 1 1 . According to certain exemplary embodiments, unitary pivoting mechanism 13 can provide head portion 1 1 to be independently adjusted relative to the handle portion 14 and head portion 1 1 can be adjustably fixed in that position. The unitary pivoting mechanism 13 can provide the head portion 1 1 to pivot relative to the handle portion 14 when a force is applied to either the handle portion 14 and/or the head portion 1 1. The unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot in one or more planes. For example, the unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot relative to the handle portion 14 in one plane. Alternatively, the unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot relative to the handle portion 14 in two planes. Similarly, the unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot relative to the handle portion 14 in three, four, or five planes. Alternatively, the unitary pivoting mechanism 13 can enable the head portion 1 1 to pivot relative to the handle portion 14 in 360 degrees.

[0033] Unitary pivoting mechanism 13 can be any mechanism by which the relative motion between the handle portion 14 and head portion 1 1 can be provided. For example, the unitary pivoting mechanism 13 can be ball-shaped or substantially spherical. According to embodiments of the present invention, the unitary pivoting mechanism 13 can be substantially enclosed within the handle portion 14 and/or head portion 1 1 so that at least a portion of unitary pivoting mechanism 13 is substantially hidden from users view. Alternatively, unitary pivoting mechanism 13 can include any mechanism that may enables head portion 1 1 to pivot relative to handle portion 14, including, e.g., a saddle joint, a ball-and-socket joint, a tension spring, or the like. The multiple planes of movement can also be provided via any mechanism. For example, unitary pivoting mechanism 13 can include a first end 18 and a second end 19. The first end may be coupled to head portion 1 1 and may provide relative motion between unitary pivoting mechanism 13 and head portion 1 1 along a first plane while being fixed relative along other planes. Similarly, the second end may be coupled to handle portion 14 and may provide relative motion between unitary pivoting mechanism 13 and handle portion 14 along a second plane while being fixed relative along other planes. Further, the first plane and the second plane may be different, thus enabling relative movement in at least the first and second planes. This pivoting mechanism can be beneficial where the callus/hardened skin or the target area to be treated is contoured or has an irregular surface. The pivoting mechanism can also be beneficial where it can enable consistent contact with the callus/hardened in view of the user moving skin treatment device 10.

[0034] Figures 5-7 show unitary pivoting mechanism 13 according to an embodiment of the present invention. As shown in Figures 5-7, unitary pivoting mechanism 13 may include first end 18 having a coupling mechanism 50 and second end having coupling mechanism 51. Coupling mechanisms 50 and 51 may enable head portion 1 1 and handle portion 14 to be coupled to unitary pivoting mechanism 13 and may also define a range of motion or pivoting between unitary pivoting mechanism 13 and head portion 1 1 and handle portion 14. For example, coupling mechanisms 50 and 51 may include elongated openings or recesses which engage with complimentary features of head portion 1 1 and handle portion 14, respectively, and facilitate pivoting between unitary pivoting mechanism 13 and head portion 1 1 and handle portion 14. For example, as shown in Figures 5 and 6, coupling mechanism 50 may include a substantially horizontal opening or recess, which can enable head portion 1 1 , which is coupled to unitary pivoting mechanism 13 via coupling mechanism 50, to pivot relative to unitary pivoting mechanism 13 horizontally. Similarly, coupling mechanism 51 may include a substantially vertical opening or recess, which can enable handle portion 14, which is coupled to unitary pivoting mechanism 13 via coupling mechanism 51 , to pivot relative to unitary pivoting mechanism 13 vertically. Accordingly, the size, shape, and orientation of coupling mechanisms 50 and 51 may dictate the type, size, and range of motion between unitary pivoting mechanism 13 and head portion 1 1 and handle portion 14. As shown in Figure 6, coupling mechanisms 50 and 51 can be substantially orthogonal to one another. Alternatively, coupling mechanisms 50 and 51 can be oriented in various angles depending on the pivoting motion that is desired. Accordingly, coupling mechanisms 50 and 51 can include any shape, size, orientation, or mechanism that enables the desired relative motion between unitary pivoting mechanism 13 and head portion 1 1 and handle portion 14.
