DETAILED DESCRIPTION OF THE INVENTION

(10) At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements of the invention. While the present invention is described with respect to what is presently considered to be the preferred aspects, it is to be understood that the invention as claimed is not limited to the disclosed aspects.

(11) Furthermore, it is understood that this invention is not limited to the particular methodology, materials and modifications described and as such may, of course, vary. It is also understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to limit the scope of the present invention, which is limited only by the appended claims.

(12) Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. It should be appreciated that the term trimming blade is synonymous with terms such as razor, cutting blade, straight edge, knife, and such terms may be used interchangeably as appearing in the specification and claims. Although any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods, devices, and materials are now described.

(13) FIGS. 1-9 show a preferred embodiment of a razor for shaving and trimming nose hair with an extendable trimming blade.

(14) The razor includes a handle 1 that is held while a user is shaving his facial hair. A head 2 is connected to the top end of the handle 1. The top end of the handle 1 is where the cutting operations occur when in use by the user. As shown in FIG. 1, head 2 includes several razor blades 3, which run laterally from one side of the head 2 (the left side) to the opposite side of the head 2 (the right side). The razor blades 3 are disposed on a face of the head 2 and are designed to cut facial hair, e.g. beard hair. A lubricating strip 4 is disposed on the face of the head 2.

(15) Each head side 11 of the head 2 has a respective trimming blade 5 for cutting nose hair and a recess. The recess of the head side 11 provides a pathway for the trimming blade 5 to extend from its respective side or retract into its respective head side 11. In a resting, or non-use state, the user depresses plunger 6, which extends the trimming blade 5 from the recess in the head side 11. The user can then use the trimming blade 5 to trim nose hairs. When the user has finished trimming his nose hairs, the user again depresses the plunger 6, which retracts the trimming blade 5 into the recess on the head side 11. When retracted, the trimming blade 5 is retracted completely within the recess of the head side 11.

(16) The trimming blade 5 has a cutting edge on its bottom edge. The trimming blade 5 is shorter than the head 2. In an exemplary embodiment, there are left and right trimming blades 5, each of which are connected to a respective plunger 6. The plungers 6 are seated in the bottom of the handle 1, opposite of the head 2.

(17) The trimming blade is extended (or deployed) when the plunger 6 engages a linkage system within the handle 1 and head 2. FIGS. 8 and 9 show the preferred embodiment of the linkage system between each trimming blade 5 and plunger 6, that is the left and right trimming blades 5.

(18) Each linkage system includes a standard retractable-pen linkage 10. A retractable-pen linkage 10 operation is known in the industry, whereby a system of springs, rods, guide pins, and other mechanical components allow the engagement of the plunger to actuate the trimming blade 5.

(19) The retractable-pen linkage 10 is actuated by pressing plunger 6. Each retractable-pen linkage 10 is connected to a respective plunger link 9. Each plunger link 9 interconnects the retractable-pen linkage 10 and a cam 7. Each cam 7 is further connected to a blade link 8. The blade link 8 interconnects the cam 7 and the trimming blade 5. The linkage forms a kinematic chain between each plunger 6 and a respective trimming blade 5.

(20) Blade link 8 and plunger link 9 are made of any material capable of withstanding the repeated actuating of the plunger 6. Materials may include metal wire or polymers. The connection of plunger link 9 to plunger 6 and cam 7, in addition to the connection of blade link 8 to cam 7 and trimming blade 5, allow for the movement of the trimming blade 5 in and out of the head 2.

(21) Actuating the plunger 6 a first time causes the trimming blade 5 to extend from the recess of head side 11 of the head 2. FIGS. 1, 2, 5, 6, 7, and 9 show the razor with at least one of the trimming blades 5 in an extended position. Actuating the plunger 6 a second time causes the trimming blade 5 to retract into the head 2. FIGS. 4 and 8 show the razor with both trimming blades 5 in a retracted position.

(22) To trim hair in a location that is narrower than the head 2 of the razor but wide enough to accommodate the trimming blade 5, a user extends the trimming blade 5 from the head 2 by pressing the plunger 6. The user places the trimming blade 5 against the hair and pulls the trimming blade 5 against the hair to be cut. When finished, the user presses the plunger 6 to retract the trimming blade 5 into the head. While facial and nose hair are described herein, the present invention can be used on other types of human hair besides nose hair, such as ear hair.

(23) As shown in FIGS. 1, 2, 6, 7, 8, and 9, the present invention optionally includes a left and right trimming blade 5. Users that are left handed and right handed can use either side of the head 2 to engage a trimming blade 5. In addition, the user's hand grip on handle 1 allows the user to use the left or right trimming blade 5 in either hand.

(24) In an exemplary embodiment, the present invention includes both a left and right trimming blade with a respective left and right linkage system. A left plunger is located on the bottom of the handle 1, on the opposite end of head 2. The left plunger is connected to trimming blade 5 through a linkage system, including a retractable pen linkage 10. When the left plunger is pressed, the linkage system deploys the left trimming blade from its retracted position. When the left plunger is actuated again, the linkage systems retracts the left trimming blade from its extended/deployed position. The same operation occurs for the right trimming blade, plunger, and linkage system.

(25) In yet another exemplary embodiment, the left and right plungers are actuated in unison to deploy the and retract the respective left and right trimming blades at the same time. Either the user pressers both left and right plungers at the same time, or a connector is engaged to link the left and right plungers so they can only operate in unison.

(26) In yet another exemplary embodiment, the present invention includes a method for deploying a trimming blade on the side of a razor head 5 for trimming nose hair. First, the user depresses plunger 6 on handle 1. Second, the linkage system connects plunger 6 to trimming blade 5 is engaged. Third, the trimming blade 5 is extended/deployed from the recess of head side 11. Next, when the plunger 6 is depressed again, the trimming blade 5 retracts into the recess of head side 11.
