Abstract
A cutter device particularly useful for cutting fingernails and toenails includes a housing grippable by a user for holding and manipulating the device. A slot is formed in a conical end portion of the housing and is elongated in the circumferential direction for receiving a nail to be cut. A rotatable head having an outer conical surface is rotatably mounted within the conical end portion of the housing. A blade is fixed to the rotatable head and has a cutting edge extending substantially radially of the conical surface of the head and perpendicularly to the slot. A motor within the housing and coupled to the head rotates the head, and the blade fixed thereto, such that the cutting edge of the blade is rotated substantially perpendicularly to the direction of elongation of the slot and the nail received therein.
Claims16
A cutter device particularly useful for cutting fingernails and toenails, comprising:
- a housing grippable by a user for holding and manipulating the device;
- a slot formed in a wall of the housing for receiving a nail to be cut;
- a rotatable head rotatably mounted within the housing;
- a blade fixed to the rotatable head and rotatable therewith;
- said blade being formed with a plurality of radial slots extending completely through the thickness of the blade, starting from its outer periphery to an unslotted region centrally thereof, to form a plurality of spaced cutting edges extending radially from said central unslotted region to the outer periphery of the blade;
- said slot formed in a wall of the housing being elongated in the direction of rotation of the head and blade;
- and a motor within the housing and coupled to the head to rotate the head, and the blade fixed thereto, such that the cutting edges of the blade are rotated substantially perpendicularly to the direction of elongation of the slot and the nail received therein.
A cutter device particularly useful for cutting fingernails or toenails, comprising:
- a housing grippable by a user for manipulating the device and having a conical portion;
- a slot formed in the housing and elongated circumferentially thereof for receiving the nail to be cut;
- a blade mounted within the housing and having a cutting edge located to extend substantially perpendicularly to the direction of elongation of said slot;
- a rotatable head rotatable about a rotary axis and having an outer conical surface substantially conforming to the conical portion of the housing occupied by said slot;
- said blade being fixed to the rotatable head with the cutting edge of the blade projecting slightly outwardly of the outer conical surface of the head;
- said outer conical surface of the head being formed with a radially-extending recess bordered on one side with a seat for mounting the blade thereto to overlie said one side of said recess with the cutting edge of the blade being spaced from, and substantially parallel to, the other side of said recess;
- and a motor within the housing for driving said blade across an undersurface of the housing just under the slot and substantially parallel to the direction of elongation of the slot, such that the cutting edge moves substantially perpendicularly to the slot and to a nail received within the slot.
A cutter device particularly useful for cutting fingernails or toenails, comprising:
- a housing grippable by a user for holding and manipulating the device, and having a conical end portion;
- a slot formed in said conical end portion of the housing and elongated in the circumferential direction thereof for receiving a nail to be cut;
- a rotatable head having an outer conical surface rotatably mounted within the conical end portion of the housing;
- a blade fixed to said rotatable head;
- said blade being also of conical configuration, conforming to the outer conical surface of the head;
- said blade being formed with a plurality of radial slots extending completely through the thickness of the blade, starting from its outer periphery to an unslotted region centrally thereof, defining a plurality of cutting edges extending substantially radially of the conical surface of the blade and perpendicularly to said slot;
- and a motor within the housing and coupled to said head to rotate the head, and the blade fixed thereto, such that the cutting edge of the blade is rotated substantially perpendicularly to the direction of elongation of the slot and the nail received therein.
