BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a device for perforating artificial fingernails.
2. Description of the Prior Art
Artificial fingernails are offered in an enormous variety of different shapes, colors and sizes by the cosmetic industry. They are glued onto natural nails and are intended to add to the well-groomed appearance of the fingers of the wearer. As a rule, artificial fingernails are intentionally long and extend by about 5 to 15 mm beyond the fingertips. Artificial fingernails are known, which are made of transparent plastic and enclose a magnifying glass, made of one piece from this plastic material, in the tip of the fingernail. Such a magnifying glass acts as ornamentation and can also be used as a reading aid. It is also known to wear expensive and real jewelry as ornamentation on the tips of the artificial fingernails. Up to now, pieces of jewelry were glued to the nails. However, gluing requires much effort and there is the danger that the connection might not hold and the piece of jewelry become lost. For this reason, the inventor recently has developed jewelry which can be inserted into a prepared hole in the fingernail. However, fingernails with factory-made prepared holes have a problem created by painting them, due to the capillary action of the nail polish, crust appear at the edges of the hole which, make the later insertion of the piece of jewelry more difficult and, tear the nail polish when the piece of jewelry is inserted. And, because the wearer would prefer to paint the artificial fingernails in a color which is coordinated with the rest of her makeup or her clothing, painting the nails will be done at home. In view of this problem, it is best to provide holes in the nails after they have been painted. This creates a clean edge around the hole, so that insertion of the piece of jewelry can take place without trouble and without damaging the polish.
SUMMARY OF THE INVENTION
It is therefore the object of this invention to provide a device which perforates an artificial fingernail, so that a suitably shaped piece of jewelry can be inserted in the resulting hole.
This object is attained in accordance with this invention by a device for perforating artificial fingernails comprising a piston-cylinder unit, where the wall of the hollow cylinder has a transverse aperture which is banana-shaped in cross section, convexly curved in relation to the piston, extends through the entire hollow cylinder, is wider than the interior diameter of the hollow cylinder and, the tip of the piston has a sharp edge honed into a knife.
BRIEF DESCRIPTION OF THE DRAWINGS
This invention will be understood in the drawings, and detailed description below, wherein
FIG. 1a is a side view of an artificial fingernail with an inserted piece of ornamentation;
FIG. 1b is a front view of an artificial fingernail with an inserted piece of ornamentation;
FIG. 2 is a diagram of a front view of a perforating device in accordance with one embodiment of this invention;
FIG. 3 is an exploded, perspective view; of a perforating device in accordance with the embodiment of this invention shown in FIG. 2; and
FIG. 4 is a lateral view of the perforating device in accordance with one embodiment of this invention with an artificial fingernail to be perforated in the position of operation.
DESCRIPTION OF PREFERRED EMBODIMENTS
An artificial fingernail 8 with an inserted piece of ornamentation is shown in FIGS. 1a and 1b. An ornamental insert is inserted into a prepared hole in the fingernail 8. It is pushed with its top from below through the hole in the fingernail 8. Because it has upper and lower edges 3, 6, between which a groove 7 is formed, the ornamental insert is securely maintained in the hole. Most often the ornamental insert is placed in the fingernail 8 of the little finger, because it is least stressed there and the fingernail 8 of the little finger is the most dainty. It is of course also possible to manufacture ornamental inserts in which the curvature of the edge i
