Definitions

  • the present invention relates to a device for punching a round hole with a saddle-shaped edge into the all-round curved surface of the front area of an artificial fingernail .
  • They are glued to the natural nails and are intended to contribute to a well-groomed appearance of the wearer's fingers.
  • Such artificial fingernails are usually very long and then protrude about 5 to 15 mm beyond the fingertip.
  • Artificial nails have become known which are made of transparent plastic and include a magnifying glass made in one piece from this plastic material in the tip of the fingernail. Such a magnifying glass acts as jewelry and can also serve as a reading aid. This idea stimulated the desire to wear even more expensive and actual pieces of jewelry made of separate material as an ornament on the tips of the artificial fingernails.
  • the wearer wants to paint the artificial fingernails in a color that matches the tone of your other make-up or your clothes, the fingernails must be painted at home. It is best to punch the nails after painting because of the problem outlined above. This creates a very clean hole edge, so that the piece of jewelry can be inserted effortlessly and the paint is no longer damaged.
  • a nail clipper which essentially consists of a piston-cylinder unit.
  • the piston is spring-loaded in the cylinder and axially displaceable by pushing it in from the outside.
  • the cylinder and the piston have an approximately crescent-shaped to crescent-shaped cross section, the inner, slight curvature forming the sectional shape.
  • the cylinder wall has a slot with a curved cross section through which the outside Fingernail is insertable.
  • the tip of the piston is designed on one side as a knife, the edge of which, like the knife of a guillotine (Quillotine), runs at an oblique angle to the curved slot.
  • This nail clipper allows you to cut the edges of your fingernails, but not punch holes in them.
  • a punch for fingernails or toenails has become known, which is designed as pliers with two arms and a lever arm additionally acting on one arm.
  • Punching tools are attached to the front of the pliers, which can be used to punch a small hole in a fingernail.
  • the holes to be punched are so small that the curvature of the nail is practically insignificant, so the edge of the hole is almost in one plane.
  • FIGS. 1a and 1b initially show an artificial fingernail 8 with a jewelry insert inserted therein in a side view for a better understanding of the invention seen here.
  • a jewelry insert is inserted into a prepared hole in the fingernail 8. It is pushed from below with its upper part through the hole in fingernail 8. Because it has an edge 3, 6 at the top and bottom, between which a groove 7 is formed, it is ensured that the piece of jewelry is held securely in the hole.
  • the jewelry insert is usually inserted into the nail 8 on the little finger, since it is least stressed there and the nail 8 of the little finger also has the most delicate effect.
  • jewelry inserts can also be made, the edge curvature of which is larger and which are then suitable for being inserted into the flatter-shaped fingernails for the other fingers, even for the thumbs. It can be seen here that the edges 3, 6 of the upper part 2 and base foot 5 of the jewelry insert are nicely aligned with the nail curvature and therefore the jewelry insert is held securely in the nail hole. Between the upper part 2 and the base foot 5 there is a cylindrical base 1, the diameter of which fits exactly into the hole in the fingernail 8.
  • the jewelry insert can also be designed as a magnifying glass. Its upper part, as well as the base and base base are then hollow cylindrical through a central bore, and a small magnifying glass is inserted into the interior of this cylinder.
  • this acts as jewelry, for example, the upper part forms a beautifully decorated edge for the magnifying glass.
  • the magnifying glass may be helpful in deciphering the small print. You then only have to run your finger over the text and recognize it the letters are magnified through the magnifying glass.
  • the difficulty which the invention has to overcome now consists in making such a hole of a precisely defined diameter positioned as precisely as possible in an artificial fingernail, taking into account the fact that the fingernail is convex in cross section.
  • the invention solves this problem basically with a punch, the hole being created by punching.
  • Figure 2 shows an example of such a punch seen from the front. It essentially consists of a piston-cylinder unit.
  • the piston is designated 9 here, the hollow cylinder 10.
  • the piston 9 is advantageously made of plastic and its diameter fits into the hollow cylinder 10 so that it is well guided in it.
  • the piston 9 is surmounted on all sides in the radial direction by a head 19, the upper side 20 of which is concave.
  • the piston tip 12 consists of a tube section made of metal, which is put over the slightly tapered end of the plastic piston. It has a sharp edge 13 ground as a knife. This edge 13 describes along the circumference of the piston tip a curve similar to two contiguous S-curves.
  • the two tips 14 thus formed are diametrically opposite one another.
  • This transverse hole 11 is intended for receiving the fingernail to be punched.
  • Its curvature 15 corresponds approximately to the transverse curvature of the fingernail in the area of the point to be punched.
  • the side wall of the hollow cylinder is concavely shaped in the area 16 below the transverse hole 11.
  • the fingernail to be punched is namely glued to the natural fingernail beforehand and afterwards the artificial fingernail is already attached to the finger and pushed into the transverse hole 11, the fingertip resting comfortably in the concave region 16.
  • the hollow cylinder 10 has on its lower side a base 17 which projects beyond the hollow cylinder 10 in the radial direction.
  • the underside of the base 17 has two concave indentations 18, which give the fingers 22, 23 hold for holding the punch.
  • the punch is actuated so that the thumb 21 of the actuating hand presses on the head 19 of the piston 10, while the index 22 and middle finger 23 of the same hand hold the base 17 on the hollow cylinder 10. In the view shown here, the thumb 21 and the index 22 and middle finger 23 of a right hand are indicated.
  • the fingernails of the left hand can then be punched. Conversely, if the left hand grips the punch in the same way, the nails on the right hand can be punched.
  • In the wall of the hollow cylinder 10 there are diametrically opposed blind holes 24 which run from above along the cylinder axis. Compression springs 25 are inserted into those blind bores 24, which on the underside of the head 19 of the piston 9 act. The piston 9 can therefore be pushed against the spring force of these compression springs 25 into the hollow cylinder 10, the sharp edge 13 of the piston tip 12 completely passing through the transverse hole 11. The curvature of the edge 13 extends to that 15 of the transverse hole 11 just rotated by 90 °.
  • the piston So that the piston remains in this position with its sharp edge 13 with respect to the transverse hole 11, it has a groove 26 in its wall, which runs along the piston axis.
  • the wall of the hollow cylinder 10 is penetrated by a grub screw 27, the tip of which protrudes into the groove 26 and on the one hand prevents rotation of the piston 9 in the hollow cylinder 10 and on the other hand limits the piston movement in the direction of the piston axis on both sides. Because, as described, the transverse hole 11 is curved on the one hand and the edge 13 of the piston tip 12 is equally curved, but these curvatures are rotated by 90 ° relative to each other, the tips 14 of the edge 13 first strike a fingernail held in the transverse hole 11.
  • Figure 3 shows the punch in an exploded perspective view. This illustration allows a better insight into the shape of the individual parts, in particular the piston 9 and the hollow cylinder 10. It can be clearly seen how the edge 13 of the piston tip 12, which acts as a cutting edge, is shaped. This edge describes a curve that resembles two connected S-curves. As a result, two rounded tips 14 are formed.
  • the piston 9 is secured in the hollow cylinder 10 by means of the groove 26 and the grub screw 27 such that the tips 14 of the edge 13 always face the zenith of the curvature 15 of the transverse hole 11 in the hollow cylinder.
  • the edge 13 then acts like a pair of scissors when the piston 9 is pushed down, when it passes through the transverse hole 11, with the edge of the cylinder bore on the surface 15.
  • the generated shear effect considerably reduces the force required for punching, so that the punch can be operated with one hand with ease.
  • the concave indentation 16 for receiving the fingertip of the finger provided with the fingernail to be punched can also be seen.
  • the artificial fingernail to be punched which has already been glued to the natural one, is pushed into the transverse hole for punching until the fingertip lies against the indentation 16.
  • the purpose of the curvature 15 is to ensure that the artificial Fignernail lies snugly on the surface for the purpose of punching, so that a clean cutting edge or punching edge can be produced.
  • Figure 4 finally shows the punch in a view from the side.
  • a finger with a nail 8 to be punched as it is placed on the punch.
  • the invention thus makes it possible in the simplest way to punch already glued-on artificial fingernails after painting in order to prepare them for receiving a jewelry insert.
  • the punch is very compact and can easily be carried in a handbag so that it is always at hand. Despite its compactness, due to its special structure, no large forces are required for punching.
  • the punch according to the invention therefore also enables delicate female hands to easily produce the desired punch holes.
