Description:
ACTUATING NAIL FILE ASSEMBLY AND METHOD

Technical Field

The present application relates generally to an assembly for the treatment of fingernails and toenails, and in particular to an assembly that actuates a file across a surface of the nail to speedily file and polish the nail with minimal effort.

Description of the Prior Art

Nail care for fingers and toes is an ever increasing interest of society. Currently, standard tools for nail maintenance have included clippers, manual files, and electric files. Each of these have disadvantages. For example, clippers require filing after use and are very dangerous with the young and elderly. Misuse of clippers often result in cutting too short and/or the production of painful“hangnails”. Manual files are used to smooth cut edges of the clippers but are often slow and require a level of expertise to do correctly. Electric files come in various forms from“dremel” style, linear, and rotary. These all require a level of skill to use adequately. Although great strides have been made with respect to the maintenance of fingernails and toenails, considerable shortcomings remain. A new device is needed to provide a safe, consistent method of filing, polishing and shaping fingernails and toenails for all ages.

Summary of the Invention It is an object of the present application to provide an actuating nail file assembly for the polishing and filing of nails. The assembly is configured to induce an actuating head that repeatedly moves back and forth in designated directions. The head is applied to the nail when activated. Pressure of the nail is applied to the head. The surface of the head is textured to accomplish one or more purposes, such as polishing or filing. The assembly can be turned on and off as desired. A power supply is used to provide electrical energy to induce movement of the head.

One object of the present application is to provide a detachable head. The head may be detached and substituted or interchanged with another head. This may occur at any time or when the textured surface loses its effect. The use of a detachable head also allows for the head to be manufactured with different contours or shapes. The radius curvature of the head may be enlarged or shrunk to fit different nail profiles. Additionally, the width may be modified. Any surface characteristic may be modified to customize the fit and shape of the head to correspond to a desired nail profile.

In one embodiment, the head is releasably coupled via a mechanical press-fit coupling. In another embodiment, the head is coupled via a magnetic coupling.

A further object of the present assembly is to permit movement of the head in multiple directions. The head may be moved in a linear movement. Likewise, the head may alternatively be moved in a radial movement. Additionally, the head may be moved in alternating linear and radial movements. The user is able to select the mode of the assembly which corresponds to the type of movement of the head.

Furthermore, an object of the assembly is to provide functional control to the user to adjust and/or regulate the speed of the head and its movement. The more important features of the assembly have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated. Additional features of the system will be described hereinafter and will form the subject matter of the claims that follow.

Many objects of the present assembly will appear from the following description and appended claims, reference being made to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

The assembly and method in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with standard tools for the care of nails. Specifically, the actuating nail filing assembly of the present application is configured to provide a safe, consistent method of filing, polishing and shaping fingernails and toenails for all ages, from infants to the elderly. A smooth and consistent filing and polishing is achieved through the generation of at least one of a radial motion and a linear motion relative to the nail. No skill is required for any of these operations beyond the initiating of the actuating nail filing assembly and the application of pressure by the nail on the file in motion. These and other unique features of the assembly are discussed below and illustrated in the accompanying drawings.

The assembly will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the assembly may be presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless otherwise described.

The embodiments and method of the present application is illustrated in the associated drawings. The assembly and method of the present application includes a main body housing used to house an assortment of hardware. Housed within the housing is a controller, a circuit board, a power supply, a powertrain, and a slider. A releasable head is coupled to the slider and is external to the housing. It is understood that the head may be wholly or partially internal within the housing in selected embodiments. The controller regulates operation of the slider and powertrain. The head is interchangeable and releasably couples to the slider. The power supply provides power which is regulated by the user through the controller. The file assembly is in communication with the power supply through a transmission/motor, or powertrain, which induces movement of the head in linear and/or radial movements. Additional features and functions are illustrated and discussed below.

Referring now to the Figures wherein like reference characters identify corresponding or similar elements in form and function throughout the several views. The following Figures describe the assembly of the present application and its associated features. With reference now to the Figures, an embodiment of the valve assembly and method of use are herein described. It should be noted that the articles“a”,“an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.

Referring now to Figure 1 in the drawings, an exemplary schematic of an actuating nail file assembly according to the present application is illustrated. Actuating nail file assembly 101 includes a housing 103, a controller 105, a circuit board 107, a powertrain 109, a slider 11 1 , a head 113, and a power supply 1 15. Assembly 101 is configured to selectively induce actuation of head 1 13 in one or more directions. Head 1 13 is configured to engage a nail of a user, such as fingernail or toenail, and work a surface or edge of the nail to a desired condition. The head may be configured to file the nail by containing an abrasive surface configured to removed portions of the nail. Alternatively, the head 1 13 may be configured to polish the nail by containing a polishing surface texture. Figures 2-9 are provided to illustrate an exemplary embodiment of assembly 101. It is understood that the particular functional size, shape, and configuration may be modified according to design constraints.

Referring now also to Figures 2 and 3 in the drawings, front views of an exemplary embodiment of assembly 101 are illustrated. Assembly 101 includes housing 103, power supply 1 15, and powertrain 109. Also included is controller 105 for regulating the operation of powertrain 109. The file assembly 1 17 includes slider 1 1 1 and head 1 13. These are moved through operation of powertrain 109, which selectively induces movement of the file assembly in a plurality of directions such that the file assembly is configured to repetitively alternate between at least two opposing directions.

In particular with Figure 3, assembly 101 is shown externally wherein housing 103 is encasing a majority of the prior discussed components. Flousing 103 is a hardened case designed to provide protection to the components and to provide a place to nest the components together in an orderly and safe manner. It is understood that housing 103 may be made from various types of materials and may have any shape. Design constraints may influence the ergonomics, functions, and characteristics of housing 103 in different applications of use.

Controller 105 is provided for interaction with a user. Controller 105 includes inputs 105a-c. Inputs 105a-c may be buttons, switches, gears, dials, and the like. Input 105a is used to turn on and off assembly 101. This acts to regulate power via power supply 1 15 to powertrain 109 and/or circuit board 107. Power supply 1 15 may be a battery or other stored power source (direct current) or may be configured to receive alternating current through a plug-in interface to the electrical grid or generator. In such an embodiment as the latter, power supply 1 15 may be located externally to housing 103. Input 105b is configured to regulate the mode of assembly 101. The mode of assembly 101 has reference to the type of movement induced upon file assembly 1 17. Assembly 101 is configured to actuate file assembly 1 17 between at least one of a linear movement and/or a radial movement. A first mode may allow a linear movement of file assembly 1 17. A second mode may induce a radial movement of file assembly 1 17. A third mode may induce both a linear movement and a radial movement in a defined sequence. Selection between the various modes may be made through a switch input or through sequential depressions of input 105b for example. Board 107 is configured to monitor and regulate the interactions of controller 105 and powertrain 109. Circuit board 107 is in communication with the power supply 1 15 and the powertrain 109. The circuit board 107 is configured to automatically regulate operation of the powertrain 109, so as to control at least one of speed of movement of the file assembly 1 17 and mode selection.

Additionally, controller 105 may include input 105c configured to regulate the speed of movement of file assembly 1 17. In this example in Figures 2 and 3, input 105c is a rotating dial with teeth configured to engage a gear 1 19. Gear 1 19 engages powertrain 109 to speed regulate the operation of motor 121. Gear 1 19 may engage either one of motor 121 and/or transmission 123 of powertrain 109. It is understood that any number of methods may be employed to regulate speed and/or change modes. The methods described herein are not intended to be limiting and serve as one manner of accomplishing such task.

It should be understood that board 107 may be configured to store one or more filing or movement profiles. This could allow for a greater selection of motions for the user to choose from. Board 107 may also permit functions such as time delay, auto speed variation, sleep mode when left on and so forth. From Figure 3 it is clear to see how slider 1 1 1 is located within a slot 120 within housing 103. The slot is shaped in the form of an arc. Movement of slider 1 1 1 laterally as viewed in Figure 3 would induce a radial motion as slider 1 1 1 traverses slot 120. More detail about the motion of file assembly 1 17 will be provided in discussion with subsequent Figures.

Referring now also to Figure 4 in the drawings, a front view of the components within assembly 101 are illustrated. In this view, housing 103 is removed to add in clarity of the components described above. Although not shown is the wiring for passing electrical current from power supply 1 15 to controller 105, powertrain 109, and/or board 107, such is to be interpreted as being present. More clearly seen in Figure 4 is the presence of stem 125 and coupler 127. Stem 125 extends from powertrain 109 and engages a rear portion of coupler 127. Referring now also to Figure 5 in the drawings, an enlarged front view of powertrain

109 is illustrated in communication with file assembly 1 17. Powertrain 109 induces movement on head 1 13 by actuating head 113 in one or more sets of direction (i.e. radial and/or linear). One manner of accomplishing this is the use of stem 125. Stem 125 extends away from powertrain 109 and couples to slider 1 1 1. As noted above, slider 1 11 translates within slot 120. Powertrain 109 is configured to move stem to induce movement of file assembly 1 17. Movement of stem 125 may occur through pivoting it about an axis point, such that the distal tip of stem 125 makes a radial arc of motion. Additionally, powertrain 109 may induce an linear movement upon stem 125. The linear motion may be inward/outward to powertrain 109, side to side, or up and down. The distal tip of stem 125 remaining linear during motion. Any combination of linear and radial may also be done.

Where slider 1 1 1 is located in a track of housing 103, such as with slot 120, some degrees of freedom may be limited. Flowever, other embodiments may limit the size or use of slot 120. In Figure 5, arrows are used to show motion of stem 125 and slider 11 1. The radial movement of slider 1 11 coincides with the shape of slot 120.

Also of note, coupler 127 and stem 125 may be pivotally coupled together or may be firmly fixed in relation to one another. The method or type of coupling may be determined partially upon the type of motion desired of file assembly 1 17 and the type of motion of stem 125.

Slider 1 11 engages with coupler 127. The manner of coupling is one which permits the desired types of movement. It is ideally desired that slider 1 11 is releasably coupled to coupler 127. In Figure 5, coupler 127 and slider 1 1 1 are shown to have interlocking teeth that nestle together. In such an embodiment it would be difficult to induce an in and out movement of stem 125 and file assembly 1 17, however other types of engagement are possible and such depiction is not limiting.

Referring now also to Figure 6 in the drawings, an enlarged side view of file assembly 1 17 is illustrated. Flead 1 13 and slider 1 1 1 are shown from the side and arrows are provided to show possible motion or movement of assembly 1 17 in an up and down direction.

Referring now also to Figure 7 in the drawings, a top and bottom view of head 1 13 is provided. Top view 131 illustrates the back surface 133 of head 1 13. Back surface 133 is adjacent to and facing slider 1 1 1. Bottom view 137 illustrates the front surface or textured surface 139 of head 1 13. Surface 139 is opposite from surface 133 and faces away from slider 1 1 1. Textured surface 139 has a texture or surface treatment different from that of other surfaces on head 1 13. Textured surface 139 may be configured to polish or be abrasive to remove material. Textured surface 139 may be formed from the application of a material that is releasably adhered to head 1 13. In other embodiments, such material may not be removable.

Referring now also to Figure 8 in the drawings, a front view of file assembly 1 17 is illustrated. In this Figure, file assembly 1 17 is depicted as being detachable. Head 1 13 is removable from slider 1 1 1. The removable nature allows head 113 to be disposable. This is useful in instances where textured surface 139 is not removable, as a worn surface would make head 1 13 less effective and inefficient and therefore require the replacement of the entire head 1 13. Of note is that head 1 13 and slider 1 1 1 are detachable from one another which lends itself to immense interchangeable possibilities. The ability to provide interchangeablility can occur through various mechanical and/or electrical attachment methods. For example, an interference fit (i.e. press-fit) may be used between slider 11 1 and head 1 13. Likewise, a non-pressing application of attachment may also be used. As seen in Figures 7 and 8, a magnet 135 and 136 may be used to provide a magnetic attraction between slider 1 1 1 and head 1 13. One or more magnets may be used. This includes the need for only one magnet to be used between slider 1 1 1 and head 1 13.

Referring now also to Figure 9 in the drawings, an enlarged front view of head 1 13 is provided. The contour of head 1 13 is designed to provide a particular nail profile to a user. The textured surface 139 is what engages the nail of the user. As nails are typically rounded at the tip of a finger or toe, the textured surface 139 would generally be concave defined through a curved axis 141 having a particular radius. The interchangeability of heads 1 13 allows for a user to select from various different textured surface 139 profiles. The arrows in Figure 9 indicate various types of modifications which may be made to affect the profile of surface 139. The arc of axis 141 may flatten or tighten up to amplify the curve with a smaller radius. It should be noted that the curve of surface 139 may be seen in both horizontal and vertical directions. Additionally, the width and/or length of surface 139 may be adjusted to be shorter or longer between heads. This function allows the user to change not only the textured surface type, but also the profile of the surface 139.

It is noted that the exact shape of slider 1 1 1 and head 1 13 are not limited to that depicted or described. The location of magnets 135 and 136 may be at any location on each item. Additionally, some embodiments may permit some rotation or relative movement between slider 1 1 1 and head 113, such as the ability of head 1 13 to pivot relative to slider 1 1 1.

The particular embodiments disclosed above are illustrative only, as the application may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. It is apparent that an application with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
