DETAILED DESCRIPTION

The invention will be understood from the following detailed description of preferred embodiments of the invention, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.

The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting.

FIG. 1 depicts a fingernail coating apparatus while coating a first elongated area.

A fingernail coating apparatus 10 includes a brush 20 and a robot 60 for controllably moving brush 20.

According to a preferred embodiment, the sectional end area 52 of brush 20 is elongated as shown by the horizontal slice enumerated 52 of brush 20, for coating a fingernail 56 of finger 58 along parallel elongated areas 54A, 54B, 54C, etc.

The maximal width of any of elongated areas 54A, 54B or 54B is the width 48 of brush 20.

Referring to FIG. 4, according to another embodiment, the hair of brush 20 may form a round shape as shown by the horizontal slice enumerated 50 of brush 20, or another shape. However, the sectional end area 52 of brush 20 becomes elongated upon pressing brush 52 onto the user's fingernail 56.

The width 78A of coated elongated area 54A, determined by a camera 68 and a controller 62, is applied by rotating brush 20, such as by a step motor 64, as depicted by rotational arrow 70.

Each of parallel elongated areas 54A, 54B, etc. is made by a motor 74, moving a carriage 34 holding brush 20 linearly, as depicted by linear arrow 72.

FIG. 2 depicts a fingernail coating apparatus while coating a second elongated area.

FIG. 3 depicts a fingernail coating apparatus while coating a third elongated area.

The rotational state 66A for coating elongated area 54A may be different from the rotational state 66B for coating elongated area 54B, and may be different from the rotational state 66C for coating elongated area 54C.

The rotational state 66C may be changed along elongated area 54C, for conforming to the width of elongated area 54C at the current location thereon.

For example, if the width 78B of elongated area 54B is determined to be the width 48 (enumerated in FIG. 1) of brush 20, then the rotational state 66B for coating elongated area 54B is determined to dispose brush 20 perpendicularly to elongated area 54B.

FIG. 4 depicts the fingernail coating apparatus of FIG. 1 while supplying the liquid to the brush.

Robot 60 normally locates brush 20 within a liquid bottle 18. Brush 20 extends from a bottle cover 22, which covers liquid bottle 18, while brush 20 is disposed within liquid bottle 18.

Robot 60 includes a horizontal rail 36, a vertical rail 34. The user may place the finger thereof within a niche 12.

FIG. 5 depicts rear portion of the fingernail coating apparatus of FIG. 1.

The rear portion 46 is intended for drying the coating, such as by a heating lamp 44.

The fingernail coating apparatus (10) may further include:

    • a liquid bottle (18), for containing the liquid (76), the liquid bottle (18) for inserting the brush (20) thereinto for receiving the liquid (76) therefrom.

The fingernail coating apparatus (10) may further include:

    • a bottle cover (18), from which the brush extends, the bottle cover (18) for covering the liquid bottle (18).

    • (c) moving the brush (20) along the elongated area (54A), for administering the liquid (76) thereto,
    • thereby substantially all points of the user's fingernail (56) are coated with one layer only.

The step of receiving the liquid (76) to the brush (20) may include the step of inserting the brush (20) into a liquid bottle (18) and removing the brush (20) therefrom.

The method may further include the step of:

    • during the step of moving the brush (20) along the elongated area (54A), rotating the brush (20),
