[ ABSTRACT An automatic manicuring device is disclosed which includes a housing, with said housing having at least one fingernail receiving slot therethrough;

flexible nail filing means mounted within said housing for movement in a plane located beneath said fingernail receiving slot;

and means for moving said filing means in said plane.

9 Claims, 5 Drawing Figures 7 AUTOMATIC NAIL FILE FIEIJD OF- THE INVENTION This invention relates to automatic manicuring de-' vices, for example, for manicuring fingernails and toenails, and more particularly to such 'a device which includesflexible nail filing'means, such as a'textured moving" belt,- as the'means'for'filing 'the nails.

BACKGROUND OF THE INVENTION In'U.S. Pat. No. 1,915,305 issued :Jline 27, l933'to M; H: Gallagher, there is disclosed an automatic mani curingdevice, in' which-a' solid grinding disc is positioned beneath "fingernail receiving: slots provided in-a protectiveenclosure. It 1 might be noted that although theprinciples of the Gallagher-patent are functionally sound, there are a number of disadvantages'associated therewith.

Specifically, and as noted above, the grinding disc of the Gallagherpatent'is a solid member; unyielding to the insertion of the fingernail. Accordingly, there would be a tendency. of a manicuring device,con'- structed in accordance with-the Gallagher patent, to cause a blunting'ofthe manicured'fingemails, rather thanproducing a smooth arcuate manicured nail, as is preferably'desiredl' Additionally, the provision of a single, grindingjdisc in "the Gallagherdevice is, inof itself,

a'disadvantage, sincer'all users of the devicehave no choice but to. employthe single degree of coarseness which has been'jpreestablished "for the single grinding disc thereof.

SUMMARY OF THE INVENTION In'contradistinction' to the prior art, as exemplified by the aforementioned'Gallagher patent, theautomatic manicuring-device of the 1 instant'invention includes flexible nail filing means which naturally yield-to the arcuate shape-ofthe nail impressed 'thereon during the manicuring sequence. Additionally, and as a further primary feature'of the instantfinvention', the manicuring device hereof includesa plurality of distinct flexible nailfiling surfaces, which are provided with differing degrees of coarseness withrespect'to one another.

Thus, the-automatic manicuring device of the instant invention broadly comprises a housing, havingat least onefin'gern'ail receiving slot therethrough; flexible nail filing-'means-mounted within said housing' for movement in aplane'locatedbeneath said fingernail recei'vin'gislot; and 'meansfor rnoving said nail filing means in I said plane. Preferably, the flexible nail "filing means comprises atleast-one textured moving belt, supported within the aforementioned housing by first and second rollers, such that a portion of the textured belt 'is'positioned in the 'planeimmediately beneaththe fingem'ail receiving-slot. Thus,.when the fingernail is'inserted in the slot, the flexible textured filingbelt can conform to the arcuate shapeofthe nail during-the filing process.

In accordance with the aforementioned second, primary aspectof theinstant invention, the housing of the device includes a second fingernail receiving slot therethrough, and the'nail filing'means includes afsecond flexible textured belt supported "within the housing by the aforementioned first and second rollers in such a manner that a portion of the second belt is always positioned-beneath the secondslot in the housing.--ln this manner, two nails can be manicured-simultaneously (be they of the same person oradifierent person), or,

and inaccordance with this aspect of the invention, the

two belts maybe provided' with differing textures to provide the user'of the device with a choice of surfaces.

In accordance with further features'of the instant invention, the device hereof is a portable, battery operated, self-contained unitnot'dependent upon the use of an =available outlet-and cord, necessarily associated therewith; Furthennore, on-off switching means is provided 'to selectively energize the motor hereof and, in

one particularly'advantageous arrangement of the invention, such a switch is provided beneath and in association" with" the aforementioned flexible nail filing means, such that themotor of the device will be automaticallyenergized when the fingernail is inserted through the aforementioned 'slot into engagementwith the flexible nailfiling means. Additionally, the housing hereof; includes a removable cover section which carries theaforementioned fingernail receiving slots,- whereby interchangeable covers with differentslot configurations may be employed.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS FIG. l is a perspective view of an automatic manicuring device constructed in accordance with the teachings of the instant invention.

FIG. 2 is a sectional view of the device shown in FlG 1 taken alongithe lines 2 -2 thereof.

FIG. 3 is a top' view of the device of FIG. 1, with th' cover thereof removed and certain other parts removed DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning to the figures, there is illustrated an automaticmanicuring device 10 constructed in accordance with the instant invention. Broadly speaking, the device 10 includes a housing 12 having one or more fingernail receiving slots 13 therethrough; flexible nail filing means broadly designated 14, mounted within the housing 12 for movement in a plane located beneath the fingernail receiving slots 13; and means 16 for mov-' ing the nail filing means 14.

In the illustrated embodiment, the flexible nail filing means 14, comprises at least one textured belt 18 supported about first and second rollers 20 and 22, such that a portion 24 of the belt 18 is positioned in the plane immediately beneath the fingernail receiving slots 13. It will be appreciated that since the belt 18 comprises what is known as a endless" belt, that a portion thereof will always lie in the plane beneath the' fingemail receiving slots 13, as the belt is driven byfthe -moving means 16 to be further described. The belt 18 may consist of any suitable flexible material, such paper, rubber, etc., provided" with a desired textured abrasive surface. For example, a strip of sandpaper,

with pre-selected coarseness maybe connected end to end to form the belt'l8. I In the illustrated embodiment, the moving means 16 comprises a motor 26, the output shaft 28 of which is linked to the roller 22 by means of a pulley 30; and -abattery 32, which may be of the rechargeable type, if desired, for selectively energizing the motor 26. In the embodiment of FIG. 2, a thumb switch 34 is provided for selectively establishing an electrical connection between the battery 32 and the motor 26. In the alternative embodiment of FIG. 5, the operating switch takes the form of a normally open switch 36 positioned beneath the upper portion 24 of the belt 18. In operation, the switch 36 is urged to its closed position to establish the electrical path between the battery 32 and the motor 26 in response to the insertion of a fingernail through the slots 13, and into engagement with the upper portion 24 of the belt. Thus, it may be said that the embodiment of FIG. 5, the manicuring device 10, is automatically self-starting. I I

In a particularly advantageous embodiment of the instant invention, the housing 12 includes more than one nail receiving slot 13, in this embodiment two such slots 13, and 13". Similarly, and as best seen in FIG. 3, the flexible nail filing means 14 comprises a second textured belt 36, supported by the aforementioned rollers 20 and 22, such that a portion 38 thereof is positioned immediately beneath the aforementioned second fingernail receiving slot. It will be appreicated, therefore, that in this embodiment, two nails can be simultaneously manicured. Moreover, and as a particularly advantageous feature of the instant invention, the two belts l8 and 36 are provided with differing textures (i.e. one coarse and one fine), whereby a choice of manicuring surfaces is available to the user.

With reference to FIG. 2, it will .be seen that the housing 12 comprises a base portion 40, and a cover portion 42, removably secured thereto by threaded members 44. The base portion 40 carries the motor 26, the battery 32, the switch 34, and the support struts 46, which rotatably support the aforementioned rollers 20 and 22. In accordance with a further feature of the instant invention, an interchangeable cover member, such as illustrated at 42' in FIG. 4,,with slots 13" of different configuration then the slots 13 of FIG. 1 may be substituted for the cover 42 of FIG. 2. For example, if the device will be used for small children or infants, it may be desirable to use the smaller dimensioned slots 13" provided in the interchangeable cover 42.

In operation the nail to be manicured is inserted through the slots 13 of FIG. 1 (or different configured slots provided in an interchangeable cover member such as 42'), and engaged with the moving, abrasive belt (or belts) positioned therebeneath. As noted, the manual switch 34'may' be depressed or the self-starting switch 36 of FIG. 5 may beemployed for energization of the motor and consequent movement of the belt. It is important to appreciate, and it is to be considereda primary aspect of the instant invention, that because the nail filing means are flexible, they will conform to the arcuate shape of the nails to be manicured, such that blunting of the nail will be prevented. I
