Abstract

There is provided a hair trimmer that has a body that houses a motor with the motor having a drive shaft that is rotatable and extends from the body, and at least three interchangeable attachments all driven by the drive shaft when each attachment is connected to the body. The at least three attachments include a linearly reciprocating hair trimmer blade assembly, a foil shaver head and a rotary nose trimmer blade assembly.

First claim

What is claimed is:

1 . A hair trimmer comprising:
a body housing a motor, the motor having a drive shaft that is rotatable and extends from the body; and at least three interchangeable attachments that include a linearly reciprocating hair trimmer blade assembly, a foil shaver head and a rotary nose trimmer blade assembly, the linearly reciprocating hair trimmer blade assembly, the foil shaver head and the rotary nose trimmer blade assembly all being driven by the drive shaft when each of the linearly reciprocating hair trimmer blade assembly, the foil shaver head and the rotary nose trimmer blade assembly is connected to the body.

2 . The hair trimmer of claim 1 , wherein the body and each of the linearly reciprocating hair trimmer blade assembly, the foil shaver head and the rotary nose trimmer blade assembly are connectable by magnets.

3 . The hair trimmer of claim 1 , wherein the body has a spring latch that is actuated by a button.

4 . The hair trimmer of claim 1 , wherein the body forms a handle portion and a trimmer head connection portion that extends from the handle portion.

5 . The hair trimmer of claim 4 , wherein the trimmer head has a housing forming a body connection portion connectable to the body and a blade support portion that is connected to a first blade.

6 . The hair trimmer of claim 5 , wherein the first blade is in a fixed position on blade support portion and a second blade is movable.

7 . The hair trimmer of claim 6 , further comprising a protrusion of a slider that is connected to the second blade.

8 . The hair trimmer of claim 7 , wherein the protrusion extends from a first side of the slider and two parallel walls extend from a second side of the slider.

9 . The hair trimmer of claim 8 , wherein the second blade is connected to the protrusion on the first side of the slider.

10 . The hair trimmer of claim 5 , wherein the body has a first slot and a second slot on opposite sides of the trimmer head connection portion and a first magnet is connected to the trimmer head connection portion in the first slot and a second magnet is connected to the trimmer head connection portion in the second slot.

11 . The hair trimmer of claim 3 , wherein the spring latch has a protuberance that is connected to the button so that when the button is pressed, a portion of the protuberance is retracted inward inside of the body and when the button is released the protuberance returns to an extended position.

12 . The hair trimmer of claim 1 , wherein the drive shaft has an extension that is off center from an axis of rotation so that the extension moves in a circular path around the axis of rotation.

13 . The hair trimmer of claim 5 , wherein the blade support portion has an exterior surface that is opposite an interior surface so that the exterior surface connects to a first blade and an opening is formed through the exterior surface and the interior surface to receive the drive shaft to move a second blade.

14 . The hair trimmer of claim 13 , wherein the body connection portion has an outer wall that extends from the blade support portion and surrounds the interior surface and a third magnet is connected to an inner surface to protrude from the outer wall and a fourth magnet is connected to the inner surface to protrude from the outer wall.

15 . The hair trimmer of claim 14 , wherein the third magnet is positioned on the outer wall to be aligned with a first magnet of the body and the fourth magnet is positioned on the outer wall to be aligned with the second magnet of the body.

16 . The hair trimmer of claim 1 , wherein the linearly reciprocating hair trimmer blade assembly is a trimmer head.

17 . The hair trimmer of claim 1 , wherein the linearly reciprocating hair trimmer blade assembly is a T-blade head.

18 . The hair trimmer of claim 1 , wherein the linearly reciprocating hair trimmer blade assembly connects to the drive shaft to convert rotary motion of the drive shaft to linear motion.

19 . The hair trimmer of claim 1 , wherein the foil shaver head connects to the drive shaft to convert rotary motion of the drive to linear motion.

20 . The hair trimmer of claim 1 , wherein the rotary nose trimmer blade assembly connects to the drive shaft so that the drive shaft moves a blade of the rotary nose trimmer blade assembly by rotary motion of the drive shaft.
