Description

FIELD OF THE INVENTION

The present invention relates to a nail file and more particularly to a nail file assembly for use on an uncooperative fauna and method of utilizing the same.

BACKGROUND OF THE INVENTION

Nail files are used to round, shorten and define nails most commonly on the feet and hands of homosapiens. Known nail files typically have an abrasive layer or coating mounted on opposite sides of a rigid and elongated member. Often, the member is made of an inexpensive material such as plastic and the abrasive layer has a limited useful life generally making the nail file disposable. Slightly more expensive nail files utilize an abrasive pad, as oppose to a coating. This pad has a cushioning effect for improved filing in some applications. Other nail files have a member made of metal with an abrasive surface integrated into opposite side of the metallic member itself. The abrasive surface may even be impregnated with diamond particulate to enhance filing efficiency. The metallic nail files often have a handle at one end with the abrasive surfaces on the other end, and are typically more expensive than the disposable nail files but have a longer useful life.

Known nail files are typically used on oneself. For instance, when filing the fingernails of one's left hand, the thumb and at least one finger of the right hand must grasp the nail file. In other situations, most common in nail salons, a cooperative client of the salon will hold his/her hand and/or foot out for a nail technician to work on the nails. In these situations, for instance, the nail technician will grasp the nail file with the thumb and at least one finger of the right hand, brace the hand or foot of the client with the left hand of the technician and pursue filing of the client's nails.

Unfortunately, when the nail filer or technician is filing the nails of another, one hand of the nail filer is dedicated to grasping the nail file. The other hand is generally dedicated to bracing of the indexes of the hand or foot of the person having the nails to be filed. When a person or fauna, in general, is uncooperative, the nail filer is limited in ability to further control or brace the subject. Moreover, although disposable nail files are inexpensive with respect to more durable files, it would still be desirable to reduce manufacturing costs further while improving upon the cushioning effect of some known files.

SUMMARY OF THE INVENTION

A nail file assembly includes a file sub-assembly that secures preferably to an index of a human hand. The sub-assembly has a flexible sheet having an outer surface that carries an abrasive layer and an opposite inner surface that preferably carries at least in-part a fastener for securing the sheet to the index. With the sub-assembly secured to an index, the remaining indexes of the hand are free to manipulate and support the index of an uncooperative fauna that carries a nail to be filed. When filing, the index carrying the sub-assembly is free to pivot back and forth across the nail of the fauna.

Preferably, the fastener is an adhesive layer that covers an inner surface of the sheet. When in a stored state, the adhesive layer is protected by a removable release film. With the release film removed, the flexible sheet may be wrapped about any one of the indexes of the hand so that the adhesive layer is adhered directly to the selected index.

Objects, features and advantages of the present invention include the ability to file the nails of an uncooperative fauna with one hand that both supports and manipulates the nails to be filed and performs the actual filing. Other advantages include the ability to cradle an infant with one arm which performing the filing method with the hand of the other arm. Moreover, the design is relatively simple and inexpensive to manufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to FIGS. 1-3 of the drawings, a nail file assembly 20 of the present invention is illustrated having a nail file sub-assembly 22 and preferably a human hand 24 of a nail filer 26 having a plurality of indexes 28 that preferably has a thumb 30 and four fingers 32. The assembly 20 is utilized to file nails 34 of a generally uncooperative fauna 36 such as a human infant or baby. As illustrated, the filer 26 may be a mother holding her baby being the fauna 36. The thumb 30 of the right hand 24 of the mother 26 preferably carries the file sub-assembly 22 leaving the fingers 32 of the right hand 24 free to manipulate, grasp and/or brace the index(s) of the baby 36 that has the nail 34 to be filed. With the right hand 24 performing both filing and bracing functions, a left arm 38 of the mother 26 is free to cradle and support the baby 36.

Referring to FIGS. 2-5, the sub-assembly 22 is illustrated in a stored state 40. A sheet 42 of the sub-assembly 22 is generally located between a fastener 44 that is preferably an adhesive layer, and an abrasive layer 46. The sheet 42 is preferably elongated and resiliently flexible and stretchable for efficient gripping and forming to the selected contours of the human hand 24. With respect to the sub-assembly 22 being in an applied state 48, as best illustrated in FIG. 2, the abrasive layer 46 is secured to an outer surface 50 of the sheet 42, and the adhesive layer 44 is disposed on an opposite internal surface 52. When in the stored state, the adhesive layer 44 is located between the sheet 42 and a removable release film 54 for protecting and generally preserving the adhesive layer 44. Preferably, the sheet 42, the release film 54 and the adhesive layer 44 are made of materials known in the art of adhesive bandages commonly used to protect minor wounds.

The elongated sheet 42 has a mid portion 56 that extends longitudinally between a first end portion 58 and an opposite second end portion 60 of the sheet 42. The abrasive layer 46 generally covers all of the outer surface 50 at the mid portion 56. The outer surface 50 at the end portions 58, 60 are preferably not covered by the abrasive layer 46 for improved attachment of the sub-assembly 22 to any one of the indexes 28 of the hand 24 of the filer 26. That is, for instances where the indexes 28 of the hand 24 of the filer 26 may be damp or generally dirty, adhesion of the sheet 42 generally to the skin of any one of the indexes 28 may be limited. However, because the sheet 42 is wrapped longitudinally about the selected index 28, the adhesive layer 44 at one of the end portions 58, 60 will adhere to the outer surface 50 at the other of the end portions 60, 58 when the elongated sheet 42 is wrapped completely around the index 28 and overlaps itself. Moreover, the end portions 58, 60 are preferably resiliently elastic contributing toward gripping the selected index.

During application of the sub-assembly 22, the release film 54 is first removed from the sheet 42, thus exposing the adhesive layer 44. The sheet 42 is then wrapped preferably about the thumb 30 of the hand 24 of the filer 26 with the adhesive layer 44 facing toward and adhering to the skin and potentially the nail of the thumb. Preferably, the sheet is orientated so that the mid portion 56 of the sheet 42 is generally against the cushioning pad 62 of the thumb 30. This provides a cushioning effect when filing. One skilled in the art however would now know that the flexible sheet 42 with the adhesive layer 44 can be adhered in any variety of locations including the palm 64 of the hand 24.

With the sub-assembly 22 secured preferably to the thumb 30 of the hand 24, the infant 36 can be cradled in the arm 38 having the other hand. The fingers 32 of the hand 24 are then free to control and support the indexes carrying the nails 34 of the infant 36. With the nails 34 held steady by the fingers 32, the thumb 30 carrying the sub-assembly 22 may then be moved back and forth against the nail 34 to be filed. One skilled in the art, however, would now know that the fauna 36 can be any variety of subjects other than an infant. For instance, the fauna 36 could be a challenged adult or a pet animal that is not likely to cooperate with the filing procedure.

Referring to FIG. 7, a second embodiment of a sub-assembly 22′ is illustrated wherein like elements to the first embodiment have like identifying numerals except with the addition of a prime symbol. Sub-assembly 22′ has an abrasive layer 46′ that covers the top surface 50 of an elongated sheet 42′ at both the mid portion 56′ and the end portion 60′. End portion 58′, however, is not covered by the abrasive layer 46′, hence, an adhesive layer retains the ability to adhere to the outer surface 50′ at the end portion 58′.

Referring to FIGS. 8 and 9, a third embodiment of a sub-assembly 22″ is illustrated wherein like elements to the first and second embodiment have like identifying numerals except with the addition of a double prime symbol. Sub-assembly 22″ does not have an adhesive layer as a fastener, and instead utilizes a hook-and-loop fastener 44″ having a hook component 66 secured to an outer surface 50″ of an elongated sheet 42″ at an end portion 58″, and a loop component 68 secured to an opposite inner surface 52″ at an opposite second end portion 60″. Although the engagement ability of the hook-and-loop fastener 44″ may not be as efficient as the previously described adhesive layer 44, the fastener 44″ enables the sub-assembly 22″ to be reused.

Referring to FIG. 10, a fourth embodiment of a sub-assembly 22′″ is illustrated wherein like elements have like identifying numerals except with the addition of a triple prime symbol. Generally, the sub-assembly 22′″ has no fastener because the sheet 42′″ is a discontinuous ring preferably made of resiliently flexible plastic. The ring 42′″ is sized to fit snugly about an index having a wide range of diameters. In order to achieve a snug fit, the ring is resiliently flexible. An abrasive layer 46′″ that may include an integral cushioning pad (not shown) is secured to an outer surface 50′″ of the ring 42′″.
