Kearns ABSTRACT: A manicuring attachment for an electric dry shaver wherein abrasive means for manicuring fingernails is adapted to be moved by the shaver operating means in a predetermined path of travel on a driven member with the abrasive means disposed in a plane inclined to the driven member.

MANICURING ATTACHMENT FOR ELECTRIC DRY SHAVER BACKGROUND OF INVENTION This invention relates to new and useful improvements in manicuring attachments for electric dry shavers. I

Manicuring attachments for electric dry shavers are well known. In some instances the attachments comprise manicuring units adapted to be substituted as needed on the shaver in place attachments the cutter head. These units usually include a driven member having an abrasive substance secured thereto and which abrasive is exposed for contact by a fingernail as the driven member is moved in a rotary, reciprocatory, or like path of travel. In use the means for imparting motion to the driven member is the same means used to drive the movable cutter of the cutter head when the latter is mounted on the shaver. In other similar devices the abrasive element has either been an integral part of the shaver or of a like power operated appliance.

These known manicuring devices and attachments present various problems in use in that in addition to requiring relatively complex mechanisms various restrictions are present in that known devices do not provide for freedom of movement of the finger in positioning the fingernail or in filing the rear and side edges of a fingernail. As a result difficulties are encountered by the user in completing a filing operation in a fast and efficient manner.

It is an object of the present invention to provide novel manicuring attachment for an electric dry shaver.

Another object is to provide novel means for mounting and positioning an abrasive element for use on an electric dry shaver. Another object is to provide novel guide means for locating a fingernail to be manicured in a preselected position relative to the abrasive substance whereby the rear surface and side edges of the extended portion of the fingernail is efficiently filed.

SUMMARY OF THE INVENTION The present invention contemplates a novel manicuring attachment for an electric dry shaver. In one embodiment thereof the attachment comprises a unit adapted for connection to the shaver operating means and which unit includes a driven member adapted'to be driven thereby in a reciprocatory path of travel. Abrasive means is mounted on the driven member in an inclined position relative thereto. A guide bar is provided in a plane parallel to the abrasive means adapted to position a finger at a predetermined distance from the abrasive means.

The above and other objects and advantages of the present invention will appear more fully hereinafter from a consideration of the detailed description which follows taken together with the accompanying drawing wherein one embodiment of the invention is illustrated.

DESCRIPTION OF THE DRAWING In the Drawing:

FIG. I is a plan view of an electric dry shaver having mounted thereon a manicuring attachment incorporating the present invention;

FIG. 2 is a sectional view taken on the line 2-2 of FIG. 1;

FIG. 3 is a sectional view taken on the line 3-3 of FIG. I;

and

FIG. 4 is a sectional view taken on the line 4-4 of FIG. 1.

DETAILED DESCRIPTION Referring now to the drawing for a more detailed description of the present invention an upper portion of an electric dry shaver casing is generally indicated by the reference numeral in FIGS. 2 and 4. Shaver 10 is ofa conventional type having a receptacle 11 in the upper portion thereof for receiving therein a cutter head (not shown). Means for driving the cutters of the cutter head comprise a pair of oscillator arms 13 and 14 (FIG. 4) which extend upwardly from a motor (partially shown and diagrammatically indicated at 15 in FIG. 2) in compartment 16 in shaver 10 for oscillation in a well-known manner in direction indicated by the arrows A and B.

The manicuring attachment made according to the present invention is generally indicated by the reference numeral 18 and is shown as disposed in the cutter head receptacle ll of 7 edge of top wall 20. A pair of cavities 26-27 are provided in the body member of manicuring attachment 18 at each side of a central interior wall portion 28 and to which wall portion 28 is secured a rectangular base plate 29 by means of screws 30. Rectangular

shaped openings

32 and 33 are provided in top wall 20 to

cavities

26 and 27 and which openings 32-33 are in alignment with a pair of openings 35-36 in base plate 29 through which project oscillator arms 13-14 (FIG. 4).

Manicuring means adapted to be driven by oscillator arm 14 is provided in cavity 27 and which driven means comprise an elongated C-shaped frame member 37. A leaf spring 38 is provided to interconnect frame 37 to oscillator arm 14 and which spring has its opposite arms secured to the bottom wall of frame 37 in any suitable manner such as by projection 39 fitted in appropriate slots in frame 37. An intermediate bow portion 40 on spring 38 (FIGS. seated on arm l4.-Abrasive means indicated by the reference numeral 41 is mounted to the top of a metal frame 42 and comprises a strip of any suitable filing substance, as for example steel file, emery board, sandpaper or similar type material for shaping fingernails through frictional abrasion. As seen'in FIG. 4 the top surface 43 of frame 42 is arranged in an imaginary plane which is inclined to the top of C-shaoed frame 37 and spaced and parallel to an imaginary plane in which is arranged inclined wall 24 of main body member 19. Frame 42 (FIGS. 3 and 4) is provided with depending appropriate tab projections inserted in corresponding slots in the top wall of frame 37 to secure abrasive means 41 thereto.

Buffing means are provided in cavity 26 of manicuring unit 18 and include a C-shaped carrying frame 45 and to the top of which is secured an arcuate frame 46 (FIG.- 2). A buffing pad 47 of suitable soft material is attached to the upper surface of frame 46. A leaf spring 48 is secured to the base of frame 46 and has a bow portion 49 seated on oscillator arm 13.

Manicuring attachment 18 is maintained within shaver 10 in a known manner as by manually manipuable latch members 52 on casing 10 and which latches 52 are provided with hooks 53 engaging resilient detent fingers 51 on base plate 29 of unit 18. Latches 52 are maintained in engaged position by spring plate 54 positioned at the base of receptacle 11 in a known manner and are operable to release unit '18 from shaver 10 by manual depression from without shaver 10 as desired.

In accordance with the above description, if it is desired to use manicuring attachment 18 as mounted on shaver 10in the above described manner, operation of motor 15 will cause

oscillator arms

13 and 14 to oscillate in the directions indicated by the arrows A and B in FIG. 4.

Frame members

37 and 45 are thereby driven in a reciprocatory path by their associated

leaf springs

38 and 48 respectively.

If it is desired to file one s fingernail, the finger is placed on guide bar 24 with the undersurface of the extended fingernail positioned thereby on the reciprocatory abrasive means 41 as indicated in FIG. 4. Slight rotative rocking of the fingernail as diagrammatically illustrated by the broken lines in FIG. 3 effects efficient filing of the undersurface and side edges of the fingernail. When the nail has been filed the same may then be cleaned and buffed by placing the nail on the buffing pad 47 as the same is reciprocated.

It will be apparent from the foregoing description that the novel manicuring attachment as described has many advantages in use. One advantage among others is that the preselected position of guide bar 24 in a parallel plane to the inclined plane of abrasive means permits predetermined positioning of the finger on attachment 18. A further advantage is that the inclination of abrasive means 41 allows for the filing of the side edges and undersurface of the fingernail in an effective and more efficient manner then previously known.

Although one embodiment of the present invention has been illustrated and described in detail it is to be expressly understood that the invention is not limited thereto. Various changes can be made in the design and arrangement of parts without departing from the spirit and scope of the invention as the same will now be understood by those skilled in the art.
