4. The apparatus of claim 2 said blade cartridge further comprises the at least one spring, the at least one plate and at least one spring fixer which are received by said post, said plate evenly distributes pressure from said spring on said first and second blades.

5. The apparatus of claim 1 wherein there is an axis of rotation formed by said blade cartridge and said second top end of said housing.

6. The apparatus of claim 5 wherein said axis of rotation is located about a center of a rear surface of said blade cartridge.

7. The apparatus of claim 1 wherein said first surface of the first blade is etched.

8. The apparatus of claim 1 further comprises at least one button for activating trimming action and wherein said housing has an exterior surface, said button is situated on said exterior surface of said housing.

9. The apparatus of claim 1 wherein said light is situated on an exterior surface of said housing.

10. The apparatus of claim 1 wherein said button also activates said light.

11. The apparatus of claim 1 wherein said agitator receiver is centrally located toward a rear side of said second blade, an opposing front side of the second blade being adjacent to the opposing second surface of the first blade.

12. The apparatus of claim 1, wherein the at least one light is arranged to illuminate an area of the user's hair during trimming.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The accompanying drawings are included to provide a further understanding of the present invention. These drawings are incorporated in and constitute a part of this specification, illustrate one or more embodiments of the present invention and together with the description, serve to explain the principles of the present invention.

(2) FIG. 1 is an explode view of the blade cartridge;

(3) FIG. 2 is a perspective view of hair trimming apparatus with a head attached;

(4) FIG. 3 is a perspective view of the hair trimming apparatus without a head attached; and

(5) FIG. 4 is a perspective view of the hair trimming apparatus without a head.

(6) Among those benefits and improvements that have been disclosed, other objects and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings. The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.

DETAILED DESCRIPTION OF THE INVENTION

(7) As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessarily to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.

(8) FIG. 1 illustrates an exploded view of the blade cartridge 3. The figure illustrates springs 34, spring fixers 35, and plates 36 which are received on posts 61 of jacket 6 of first blade 4. The Figure further illustrates second blade 5 with holes 51 which posts 61 run through. The figure further illustrates agitator receiver 32 of second blade 5. The blade cartridge 3 is made for a movable stacked arrangement. The second blade 5 is designed to be placed on top of the first blade 4. The holes 51 on the second blade 5 are designed to be received by the posts 61 of first blade 4. The holes 51 have a length that is greater than the diameter of the posts 61, this allows the second blade 5 to reciprocate to create a cutting action. The second blade 5 is secured in position adjacent the first blade 4 by blade fixers 35 that use springs 34 and plates 36 to create the optimal tension between the blades for the most effective cutting action. The agitator receiver 32 receives the agitator 14 to create the actual motion for the cutting action.

(9) FIG. 2 illustrates the hair trimming apparatus having a housing 1 having opposing ends, a first bottom end forming a handle 12 and a second top end comprising an agitator 14. A head 9 is attached to the second top end of the housing 1. The head 9 covers at least a portion of the agitator 14 when attached to the second top end of the housing 1. A blade cartridge 3 is pivotally attached to the head 9 at the second top end of the housing 1. The figure further depicts the blade cartridge 3, showing the first blade 4 with a rear surface 41 having an etching (or etched surface) 42 and the jacket 6. The figure further illustrates the housing 1 having an exterior surface 11 and a light 8. The light 8 provides illumination for the area that the hair trimming apparatus is being used. The etching 42 on the rear surface 41 provides for smooth movement over a user's skin.

(10) FIG. 3 illustrates the hair trimming apparatus with housing 1 without a head or blade cartridge 3 attached. The figure shows the agitator 14, light 8, and exterior surface 11 of the housing at the first end 12. The housing 1 has a mostly hollow internal cavity (not shown). The internal cavity of the housing contains a power source (not shown) that is connected to a motor 15 and a transmission 16 that is connected to and drives the agitator 14. The motor 15 is also connected to circuitry and wire that link it to the button 7, the button 7 allows a user to tum the device on and off. The internal housing further contains a power source (not shown) that can be a disposable or rechargeable battery. The power source provides the energy to operate the motor 15, the motor 15 and power source are connected to one another.

(11) FIG. 4 illustrates the hair trimming apparatus with housing 1 without a head attached. The figure shows a button 7 that is at the first end (handle) 12 of the housing 1. The button 7 is linked to internal circuitry and wire that allow the user to power the hair trimming apparatus on and off.

(12) Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the attendant claims attached hereto, this invention may be practiced otherwise than as specifically disclosed herein.
