DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGs. 1-2B, the present disclosure shows a combination powered grooming device (100) that includes a handle (200) and a grooming attachment (300) mounted to the handle (200). FIG. IA shows a cross-sectional view of the device of FIG. 1 taken along line I-I. The handle (200) has a longitudinal axis (202) that extends between an upper end (204) and a lower end (206). In an embodiment, the handle (200) may have a width of less than about 35 mm, or even less than about 27 mm. A trimmer assembly (208) is disposed adjacent the upper end (204) of the handle (200) and includes at least one moving blade (210). The handle (200) may be constructed to be held by a user during operation such that the internal components, i.e., an electrical arrangement (212), are impervious to liquids. The lower end (206) of the handle

(200) may include a removably attached cap for accessing these components.

The electrical arrangement (212) is disposed in the handle (200) and is configured to supply power for operating the trimmer assembly (208). The electrical arrangement (212) includes a motor (214) and a drive mechanism (218). The motor (214) has a drive shaft (216) for driving the moving blade (210) and may also vibrate at least the handle (200). In an embodiment, the motor (214) has a diameter less than about 18 mm, a peak efficiency less than or equal to 55%, and an output torque less than about 0.8 mNm at peak efficiency.

The drive mechanism (218) may be coupled to the drive shaft (216) and to the trimmer assembly (208). In a trimming mode, shown in FIG. 2A, the drive mechanism (218) is coupled to the trimmer assembly (208) and translates the rotational movement of the drive shaft (216) to lateral reciprocating movement of the moving blade (210). In the trimming mode, the trimmer assembly (208) functions as a powered trimmer that typically operates by reciprocally moving back and forth a moving blade (210). The moving blade typically (210) has a series of teeth that operate to cut hair in a scissoring fashion as the teeth of the moving blade (210) move past the teeth of the stationary teeth when the motor (214) is turned on. A trimmer comb (238) may be positioned over the trimmer assembly, as shown in FIG. 3, for trimming the hair to a desired length.

In a grooming mode, shown in FIG. 2B, the drive mechanism (218) is decoupled from the trimmer assembly (208) such that the drive shaft (216), with or without the drive mechanism (218) coupled, may rotate, but such movement is not translated to the moving blade (210). In this configuration, the motor (214) continues to operate, which vibrates at least the handle, but power is no longer supplied to the trimming assembly (208) thereby stopping the movement of the moving blade (210).

The electrical arrangement (212) may also include a power source, a controller, a printed circuit board ("PCB"), a switch, and a light operatively connected to the PCB. Various power sources, e.g., radiant, kinetic, potential, thermal, magnetic, gravitational, sound energy, light energy, electrical, electromagnetic, chemical source, and combinations thereof, may be used. The electrical arrangement (212) may also include an energy storage device, e.g., coin cell, double layer capacitor, solar cell, battery, or other suitable storage device. In an example, the energy storage can be configured to provide inductive charging via an external charging station. The handle (200) may include a switch disposed thereon such that the switch is in operative communication with the electrical arrangement (212). Additionally, the switch may be illuminated by a light source on the electrical arrangement (212).

As shown in FIGs. 1-lB, the grooming attachment (300) mounts onto the upper end (204) of the handle (200). This mounting can be accomplished by a snap-fit connection, an interference fit, or other suitable ways to secure the grooming attachment (300) to the handle (200). As shown, the grooming attachment (300) is a razor assembly (302) having a cartridge connecting structure (304) connected to a razor cartridge (306). The razor cartridge (306) includes at least one elongated blade (308) mounted therein. For example, U.S. Patent 7,168,173 generally describes a Fusion® razor with multiple blades and a stationary trimming blade that is commercially available from The Gillette Company. Additionally, U.S. Patent 6,185,823 describes a Venus® razor having an oval framed cartridge having multiple blades that is commercially available from the Gillette Company. The grooming attachment (300) may also include an ejection mechanism for removably attaching the razor cartridge (306) to the connecting structure (304). Referring to FIGs. 4A-4D, the drive shaft (216) may include an eccentric weight (220) mounted thereto. The eccentric weight (220) may vibrate at least the handle (200). Alternatively, the eccentric weight (220) may reduce the vibration about the trimmer assembly (208) by compensating for the movement of the moving blade (210). As shown, the eccentric weight (220) includes a crank lever (222) for driving the drive mechanism (218). In the trimming mode, the crank lever (222) translates the rotation of the drive shaft (216) to the drive mechanism (218) for operating the moving blade (210). In the grooming mode, the crank lever (222) is generally positioned above the drive shaft (216) and motor axis, so that the crank lever (222) rotates without cranking, i.e., the trimmer assembly (208) does not operate, but the handle (200) continues to vibrate.

A counterweight (224) may also be mounted to the drive shaft (216). In the trimming mode, shown in FIGs. 4B and 4D, the eccentric weight (220) and the counterweight (222) are at least substantially balanced so that the trimmer assembly (208) is driven by the crank lever (222). In the grooming mode, shown in FIGs. 4A and 4C, the eccentric weight (220) and the counterweight (222) are less than substantially balanced. Changing between the trimming mode and grooming mode can be done by changing the orientation of rotation of the motor (214). For example, a rotation in a clockwise direction causes the inertia moment of the eccentric weight (220) to fall into its balanced position. Rotation in a counterclockwise direction causes the inertia moment of the eccentric weight to move into its unbalanced position. Referring to FIGs. 5A-6B, the handle (200) may include a decoupling mechanism (226) that is engageable by the grooming attachment (300). Engaging the decoupling mechanism (226) causes the drive mechanism (226) to decouple from either the trimmer assembly (208) and/or the entire drive shaft (216), thereby resulting in a grooming mode. For example, as depicted, the decoupling mechanism (226) is spring-loaded and movable in a direction generally parallel to the longitudinal axis (202). In the trimming mode, the decoupling mechanism (226) is in a rest position, shown in FIGs. 5A and 6A. Upon engagement with the grooming attachment (300), i.e., mounting the grooming attachment (300) over the trimmer assembly (208), the decoupling mechanism (226) is moved in a generally downward direction resulting in the grooming mode, shown in FIGs. 5B and 6B. Removing the grooming attachment (300) causes the spring to return the decoupling mechanism (226) back to the rest position. Other suitable ways, e.g., electrical or electromechanical, for decoupling the drive mechanism (226) from either the trimmer assembly (208) and/or the entire drive shaft (216) is also contemplated. Additionally, the drive shaft (216) may be separable into a top portion (216a) and bottom portion (216b).

Now referring to FIGs. 5A and 5B, the electrical arrangement (212) includes an eccentric weight (228) rotatably mounted to the top portion (216a) of the drive shaft (216), a first gear (230) mounted to the bottom portion (216b) of the drive shaft (216) and connected to the decoupling mechanism (226). The electrical arrangement (212) also includes a second gear (232), which has a top portion (232a) and a bottom portion (232b), positioned adjacent to the drive shaft (216). The eccentric weight (228) vibrates at least the handle (200) when the trimmer assembly (208) is in the grooming mode. In the trimming mode, as shown in FIG. 5A, rotation of the bottom portion (216b) is translated to the top portion (216a) and ultimately to the moving blade (208). However, in the trimming mode, the eccentric weight (228) does not rotate.

Engaging the decoupling mechanism (226) with the grooming attachment (300) causes a shift from the trimming mode, shown in FIG. 5 A, to the grooming mode, shown in FIG. 5B. In the grooming mode, the top portion (216a) of the drive shaft (216) is separated from the bottom portion (216b) of the drive shaft (216), the bottom portion (232b) of the second gear (232) is engaged with the first gear (230) and the top portion (232a) of the second gear (232) is engaged with the eccentric weight (228). In this configuration, rotation of the first gear (230) is translated to the eccentric weight (228) by rotation of the second gear (232), thereby resulting in increased vibratory motion on at least the handle (200).

Referring to FIGs. 6 A and 6B, the electrical arrangement (212) includes an eccentric weight (234) rotatably mounted to the bottom portion (216b) of the drive shaft (216). A movable device (236) is also mounted to the bottom portion (216b) of the drive shaft (216) adjacent to the eccentric weight (234). The eccentric weight (234) vibrates at least the handle (200) when the trimmer assembly (208) is in the grooming mode. In the trimming mode, as shown in FIG. 6A, the movable device (236) is slidably positioned along both the top (216a) and the bottom (216b) portions of the drive shaft (216) and is configured to translate the rotation of the bottom portion (216b) of the drive shaft (216) to the top portion (216a) of the drive shaft (216). In this configuration, the eccentric weight (234) does not rotate. Engaging the decoupling mechanism (226) with the grooming attachment (300), shown in FIG. 6B, causes a shift from the trimming mode to the grooming mode. In the grooming mode, the movable device (236) is slidably positioned along the bottom portion (216b) and engaged with the eccentric weight, thereby resulting in increased vibratory motion on at least the handle (200).

In addition, the device (100) may be arranged in a kit or package. The kit comprises the device of the present invention and an accessory selected from the group consisting of a cleaning brush, a trimmer comb, a cleaning solution, a cloth, a power cord, a battery, a cover, a razor cartridge, a lubricant, toothpaste, a fluid for applying to a user, and combinations thereof. Other suitable accessories are contemplated. Alternatively, the kit may comprise the device (100) and a grooming attachment selected from the group consisting of a razor assembly, a dry shaver assembly, a toothbrush assembly, a brush assembly, a nose hair trimmer assembly, an ear hair trimmer assembly, an exfoliator assembly, and combinations thereof.

FIGs. 7-11 show other grooming attachments, e.g., a razor assembly (502), a dry shaver assembly (504), a toothbrush assembly (506), a nose hair trimmer assembly (508), an exfoliator assembly (510), and combinations thereof, that may be mounted onto the upper end (204). Other suitable grooming attachments may also be used. In some embodiments, the grooming attachment may be configured to couple with the drive mechanism (218) when the trimmer assembly (208) is in the grooming mode.

The present disclosure also features a method of using the combination powered grooming device. The method comprises providing a handle and attaching a grooming attachment onto the upper end. The handle has a longitudinal axis extending between an upper end and a lower end. The handle comprises a trimmer assembly disposed adjacent the upper end and the trimmer assembly having at least one moving blade. The handle has an electrical arrangement disposed therein. The electrical arrangement includes a motor having a drive shaft and a drive mechanism coupled to the drive shaft and to the trimmer assembly. In a trimming mode, the drive mechanism translates movement of the drive shaft to the moving blade. The method may also include a subsequent step of decoupling the drive mechanism from the trimmer assembly or drive shaft which defines a grooming mode. The decoupling step may be performed in various ways, as shown in FIGs. 2A, 2B and 12A-16B. For example, the decoupling step (706) may be achieved by changing the rotation of the drive shaft from a forward direction to a reverse direction. Alternatively, the decoupling step (706) may be accomplished by moving the trimmer assembly in a direction generally transverse to the longitudinal axis, as shown in FIGs. 2A and 2B. FIG. 2A shows the trimmer assembly (208) in the trimming mode. Tilting the trimmer assembly (208) in a direction generally transverse to the longitudinal axis (202), shown in FIG. 2B, will decouple the drive mechanism (218) resulting in the grooming mode.

Referring to FIGs. 12A and 12B, the trimmer assembly (208) may be pivotable to provide for trimming at various angles. As shown, the trimmer assembly (208) is pivotable between a minimum and a maximum pivot angle. In the trimming mode, the trimmer assembly (208) is pivoted from the longitudinal axis (202) at an angle greater than about 15 degrees. In the grooming mode, the trimmer assembly (208) is positioned at an angle less than or equal to 15 degrees. Other angles are contemplated so long as the trimmer assembly (208) is decoupled in the grooming mode and operational in the trimming mode. Alternatively, FIG. 13A shows the trimmer assembly (208) in the trimming mode. The trimmer assembly (208) can be decoupled by sliding in a direction generally transverse to the longitudinal axis (202), shown in FIG. 13B.

Referring to FIGs. 14A and 14B, the drive mechanism (218) may also be decoupled by rotating the trimmer assembly (208) about the longitudinal axis (202). Alternatively, as shown in FIGs. 15A and 15B, the trimmer assembly (208) may be moved in a direction generally parallel to the longitudinal axis (202) such that the distance (di) between the trimmer assembly (208) and the drive mechanism (216) in the trimming mode is less than the distance (d₂) of the trimmer assembly and the drive mechanism after decoupling. Now referring to FIGs. 16A and 16B, the motor (204) or any portion thereof may be moved in a direction generally parallel to the longitudinal axis (202) such that the distance (d₃) between the motor (214) and trimmer assembly (208) in the trimming mode is less than the distance (d₄) between the motor (214) and the trimmer assembly (208) after being decoupled.
