Description

BACKGROUND OF THE INVENTION

This invention relates to filing and/or trimming fingernails and toenails, and, more particularly, to an electrical apparatus for filing and/or trimming fingers or toenails by selectively applying a moving surface.
A conventional way of trimming one's fingernails or toenails is with the use of a nail clipper or a scissor. These devices leave the nail course or jagged edged, and it is common to file the edge of the nail with either an “emery” board or sometimes with a metallic file in order to smooth out the nail edge. Emery boards are pieces of hard wood or wood-like board which have emery affixed or have emery paper glued to them, thereby rendering them both coarse and flexible. They are widely used by individuals and beauty shop manicurists to shape and smoothen the nail. Because emery boards are made inexpensively so as to be disposable, they are a sanitary alternative to metal nail files. The flexibility of an emery board also makes this method preferred over the use of a metallic file. In addition to filing, the emery board also can be used as a trimming device in place of a clipper or scissor.
The problem of manually using an emery board is that it is both a tiring and time consuming process. Accordingly, it would be desirable to provide an apparatus or device which enables one to file and smooth out a fingernail using an emery board and which operates rapidly in cutting and filing the nail.

SUMMARY OF THE INVENTION

Generally speaking, in accordance with the invention, an apparatus for trimming a person's nails is provided. The apparatus comprises a body having a longitudinally extending handle that is connected to a longitudinally extending base with the base being co-extensive with and spaced from the handle. Housed within the body is a power supply for supplying power to the device as well as an electrical drive device that is powered by a power supply. The base of the apparatus has a bottom portion having a longitudinally extending support or mounting plate. The support or mounting plate removably captures an emery board or similar nail file element. The support or mounting plate is mechanically coupled to the drive device and is reciprocally moveable in a longitudinal direction in response to the drive device being electrically activated.
In one embodiment, the support or mounting plate is formed with a pair of spaced-apart longitudinally extending fins between which the emery board is captured. In its preferred design, the spaced-apart fins are outwardly moveable in a transverse direction by means of a spring mechanism so that the emery board or nail file can be disposed therebetween for capture by the fins.
Accordingly, it is an object of the invention to provide an improved apparatus for trimming a person's nails.
Another object of the invention is to provide an improved apparatus for trimming a person's nails that is easy and safe to use. A further object of the invention is to provide an improved apparatus for trimming a person's nails which utilizes replaceable emery boards sold in the market place.
A further object of the invention is to provide an improved apparatus for trimming a person's nails which controllably applies a reciprocal moving abrasive surface.
Still other objects and advantages of the invention will, in part, be obvious and will, in part, be apparent from the following description.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring first to FIGS. 1 and 2, an electronic nail file or nail trimming apparatus, generally indicated at 11, is shown. Nail file apparatus 11 is defined by a substantially U-shaped moulded body 13 made of plastic or metal. Body 13 includes a longitudinally extending handle portion 15 and an integrally formed longitudinally extending base portion 17. Handle portion 15 and base 17 are co-extensive with and spaced from one another. Body 13 is further defined by top wall 19, side walls 21 and bottom wall 23. Handle portion 15 of apparatus 11 is formed with a selectively removable front panel 20 (see FIG. 3) for enabling access inside apparatus 11.
Referring to FIG. 3, the inside of apparatus 11 is now shown. Apparatus 11 is formed with a pair of tubular compartments 33 for removably housing a pair of replaceable batteries 31 within handle portion 15. Rearwardly of battery compartments 33 is a motor 35 fixedly mounted within apparatus 11. Motor 35 is an electrical communication by means of wires 35 with a switch 37. Switch 37 is selectively activated by means of an operating button 38 protruding along the rear portion of top wall 19. When button 38 is pressed, it closes the circuit within switch 37, thereby activating motor 35. Motor 35 has a rotatable shaft 41 that is connected to a clutch unit 43. Clutch unit 43 consists of a first clutch member 47, rotatable in response to the rotation of shaft 41, and a second clutch member 49, reciprocally moveable in response to the rotation of first clutch member 47. Second clutch member 49 has a first pair of supporting feet 51A downwardly depending from the forward portion thereof and a second pair of feet 51B downwardly depending from the rear portion thereof. Feet pairs 51A and 51B are fixed to a longitudinally extending mounting plate 25 slidably moveable in a longitudinal direction with respect to bottom wall 23 of apparatus 11 (see also FIG. 4).
Referring to FIGS. 3-5, mounting plate 25 is integrally formed with a pair of longitudinally extending and downwardly depending ribs 27. Ribs 27 are spaced apart from one another such that a conventional emery board 29 can be captured therebetween and overly plate 25. In order to capture emery board 29 along mounted plate 25 and between ribs 27 (see FIG. 4), emery board 29 may be slid therewithin from one end of bottom wall 23. Alternatively, ribs 27 may be moulded to be slightly outwardly flexible in order for an emery board to be inserted between ribs 27 for capture thereby.
In operation, the user presses a button 38, which activates switch 37, thereby causing motor 35 to operate. When motor 35 operates, it causes second clutch member 49 of clutch unit 43 to reciprocally move in a longitudinal direction. Because second clutch member 49 is coupled to mounting plate 25, by means of feet pairs 51A and 51B, mounting plate 25, with captured emery board 29, reciprocally moves back and forth at a high rate of speed. Such movement of mounting plate 25 with captured emery board 29 effectively mimics the movement of an emery board during a manual application to a nail. The advantage, of course, is that the rate of the speed of reciprocal movement is far greater than could be manually generated.
As can be appreciated, once emery board 29 has worn out as a result of extensive use of apparatus 11, it may be removed from capture along mounting plate 25 and replaced with a new emery board. In addition, the captured emery board, whether or not it is worn out, may be replaced in position over moving plate 25 by an emery board having a different coarseness level.
Referring now to FIGS. 6-8, a second embodiment of the inventive nail trimming apparatus is shown. In this embodiment, bottom wall 23 has a pair of space slots 26 through which pairs of feet 51A and 51B extend with the ends of pairs of feet 51A and 51B being fixed to a mounting plate 25 ^l. Mounting plate 25 ^lhas a pair of spring elements 53 fixed thereto along the underside thereof. Each of spring elements 53 (see FIG. 6) has a hub 57 and rivet 59 which fixedly attaches hub 57 to the underside of mounting plate 25 ^l. Each of spring elements 53 further includes a pair of spring arms 55. One of spring arms 55 of each spring elements 53 is fixedly attached along the inside surface of a first longitudinally extending moveable fin 27 ^l; similarly, the other spring arm 55 of each spring element 53 is attached along the inside surface of a second longitudinally extending moveable fin 27 ^l.
Accordingly, and as shown in FIGS. 6 and 8, each of moveable fins 27 ^l, which are substantially parallel to and spaced from one another, may be selectively urged in an outward transverse direction in order to enlarge the space therebetween so as to enable emery board 29 to fit along the underside of mounting plate 25 ^l. Once emery board 29 is in appropriate position along the underside of mounting plate 25 ^l, fins 27 are released and spring arms 55 of spring elements 53 urge fins 25 ^ltowards each other in the position shown in FIG. 6. As a result, fins 27 ^lnow capture emery board 29 therebetween.
In FIG. 9, a packaging unit, suitable for sale and purchase is shown at 61. Packaging unit 61 houses a single inventive nail file apparatus 11 and a plurality of different emery boards 29A, 29B and 29C. Each of emery boards 29A-29C can be manufactured to have a different coarseness level as compared to the coarseness of the remaining emery boards housed in packaging 61. Alternatively, each emery board 29A-29C may have different width size; in accordance with the inventive embodiment of FIGS. 6-8, different width size emery boards may be accommodated for capture along the bottom of apparatus 11.
The invention accordingly comprises the features of construction and arrangement of parts as exemplified in the claims.
