Abstract
A battery powered manicuring device is taught which uses an improved drive mechanism for reciprocating a manicuring implement. A battery energizes a motor. Extending from one end of the motor is a shaft. Interconnected with the shaft is an offset device comprising either a bearing or a sleeve positioned at a non-perpendicular angle with respect to the shaft. The lower end of an attachment arm is affixed to the outer portion of either the offset bearing or the offset sleeve. The upper end of the attachment arm is affixed to the lower end of a manicuring implement. As the shaft rotates, a reciprocating motion is imparted to the attachment arm and thus to the manicuring implement.
Claims15
A power manicuring device, comprising:
- an elongate hollow housing,
- an electrically powered motor means disposed in said housing,
- a source of electrical energy disposed in said housing and adapted to energize said motor means,
- a shaft extending from said motor means and rotatable about a shaft axis,
- an offset plate interconnected with said shaft and rotatable about said shaft axis,
- an attachment arm attached adjacent to the outer periphery of said offset plate and movably responsive to rotation by said offset plate,
- guide means for restricting movement of at least a portion of said attachment arm to a substantially linear direction, and
- a reciprocating manicuring implement interconnected with said attachment arm and driven linearly in both directions along its longitudinal axis by said electrically powered motor means.
A power manicuring device, comprising:
- an elongate hollow housing,
- an electrically powered motor means disposed in said housing,
- a source of electrical energy disposed in said housing and adapted to energize said motor means,
- a rotatable shaft extending from said motor means,
- a rotatable inner portion interconnected with said shaft,
- bearing balls encircling said inner portion,
- a non-rotatable outer portion encircling said bearing balls,
- said inner portion, said bearing balls, and said outer portion comprising an offset means,
- an attachment arm connected with said outer portion and movably responsive to rotation by said inner portion,
- guide means for restricting movement of at least a portion of said attachment arm to a substantially linear direction, and
- a manicuring implement interconnected with said attachment arm.
