    Abstract: A haircutter handle has upper and lower housings. The upper housing and lower housing join to form a circumvoluted and/or spiraled exterior surface. The handle narrows and extends axially from a blade end to a handle or gripping end. The blade has an upper blade that oscillates over the lower blade to cut hair. The handle has a reduction taper that facilitates gripping and/or handling the handle. The taper also orients the motor and battery so that the center of gravity is positioned within the palm of the user's hand when gripping the handle. The blade end of the handle has a width and/or height that are greater than a width and/or height at the handle end. The reduction in height and/or width dimensions define a taper. In some embodiments, the width tapers more than the height tapers to facilitate gripping the handle about the center of gravity.

    Abstract: A haircutter handle is described that has upper and lower housings. The upper housing and lower housing join to form a pliable exterior surface. The handle narrows/tapers as it extends axially from a blade end to a gripping end opposite the blade. The blade has an upper oscillatory blade that oscillates over a stationary lower blade to cut hair. The handle's taper facilitates grasping by locating the motor and battery so that the center of gravity is located within the palm of the user's hand. The width and/or height at the blade end is greater than at the handle or grip end, and the reduction in height and/or width dimensions define the taper to locate the user's hand relative to the center of gravity. In some embodiments, the width tapers more than the height tapers to facilitate gripping handle about the center of gravity.

    IPC: B26B19/12

    Abstract: A cutter system for an electric shaver and/or trimmer, having a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and at least one field of cutting perforations between the rows of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure with an inner one of the cutting elements being sandwiched between an outer one the cutting element and the support structure. The support structure includes a pair of outer frame portions and a pair of inner frame portions supporting the inner cutting element. The inner frame portions form rigid support ribs extending from a base portion of the support structure at a steeper angle than the outer frame portions and forming rigid support edges supporting the inner cutting element along the outer edge of the field of cutting perforations.

    Abstract: A shaver head assembly includes at least one cutting head component having a housing, an inner cutting blade mounted to the housing and configured and adapted to rotate about an axis and an outer cutting disc coaxially mounted about the axis. The outer cutting disc is configured to oscillate about the axis through positive and negative predetermined angular sectors of rotation, and is configured to cooperate with the inner cutting blade to cut hair.

    Abstract: In a hair grooming appliance, a head is detachably mountable on a handle having a motor and a receptacle configured to receive at least a portion of the head therein when the head is mounted on the handle with the head in operative connection with the motor. The handle has a first attachment member positioned at least partially within the receptacle and arranged to detachably engage the head when the at least a portion of the head is inserted into the receptacle and a second attachment member positioned at least partially within the receptacle and arranged to engage the head when the at least a portion of the head is inserted into the receptacle. The second attachment member is a different type of attachment member than the first attachment member. In a particular embodiment, the hair grooming appliance is a shaver.

    Abstract: An electrically driven device provided with a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft mounted in the housing for performing a pivoting is disclosed. The driven shaft is indirectly coupled to the drive shaft by means of a gear mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The gear mechanism comprises one intermediate shaft having a second rotary axis extending in the longitudinal direction of the intermediate shaft and at least one crank arm coupled to the drive pin. The crank arm is pivotably mounted in the housing and is coupled to the intermediate shaft thereby converting a rotary motion of the drive shaft into a reciprocating pivoting of the intermediate shaft about the second rotary axis. The intermediate shaft is coupled to the at least one driven shaft by means of a pivotable bridge such that the intermediate shaft is offset with respect to the at least one driven shaft.

    Abstract: Provided is an oscillating motor and electric clippers. The oscillating motor includes a U-shaped magnetic yoke, four permanent magnets and a swing arm. The U-shaped magnetic yoke causes end faces of two support legs to produce alternating magnetic poles with the control circuit. The four permanent magnets are fixedly mounted to an inner arm via a second magnetic yoke. The four permanent magnets are sequentially distributed on a same circumferential surface having a fulcrum being a circle centre. The polarities of radial end faces of the first permanent magnet and the fourth permanent magnet are the same. The polarities of radial end faces of the second permanent magnet and the third permanent magnet are the same, and the opposite of the polarity of the radial end face of the first permanent magnet. When a coil is electrified, the four permanent magnets produce torque having the same direction of rotation.
