Description

The invention relates to a fingernail clamp, as used in the so-called pinching.

In the field of cosmetics, the care of fingernails plays a major role for many women. In addition to the care and painting of natural fingernails belongs in many cases, the use of artificial fingernails. The application and design of artificial fingernails has now grown into a significant industry. In addition, competitions are held in this area, which also produce particularly sophisticated fingernail designs from an artistic point of view.

In the design of artificial fingernails, an artificial fingernail (tip) can be glued to the end of the fingernail before the surface is evened out by applying a gel. Subsequently, a further treatment, for example, a painting etc. take place.

In another frequently used way of producing artificial fingernails, skin residues are first removed from the nail plate and a dehydrator is applied to the nail plate to remove moisture therefrom. Subsequently, a modeling material is applied to a template fixed to the fingernail to model the free nail tip. The entire modellage can then be coated with a clear coat. The modeling is usually done on the basis of acrylic with a powder-liquid mixture or by applying a gel. Acrylic-based fingernails are harder and more durable, gel nails have the advantage that they are very flexible and scratch-resistant. In addition, the production of gel nails does not produce the unpleasant odors typical for the processing of acrylic nails. As a rule, in the production of gel nails hardening under UV light must take place, which is not necessary in the production of acrylic nails.

In particular, in the production of acrylic nails but also in the production of gel nails can be performed after the modeling of the fingernail an additional step that so-called pin. When pinching the side lines of the nail are compressed, d. H. the curvature is enhanced so that when viewed from the front, there is a visually appealing C-curve. In addition to the visual appearance of the pin has the additional advantage of a longer shelf life of the product, since the curvature of the tunnel is also associated with a reinforcement of the nail and lower risk of breakage. If the material used for modeling is already slightly hardened, but still elastic. When making acrylic nails, wait for a short time to reach a sufficient level of hardening; when making gel nails, the modeling is usually done in a light curing device (about 10 to 15 seconds) before the nail is pinched is brought into shape.

When pinching a small metal tube is usually placed under the fingernail, the top of the free nail tips is z. B. compressed with tweezers and attached a clamp on the fingernail to ensure curing in the pimped form.

As terminals so far usually very simple terminals are used, which roughly have the shape of a caliper. The fingernail is formed by applying the clamp in shape, with the legs of the clamp are held together by means of a rubber band.

In this prior art, the disadvantage is that the pinch terminals require a lot of space and due to the uncertain attachment threaten to slip on the fingernail with careless handling. The fixation of the fingernail is often not optimal. So that the clamp does not slip or even fall, the customer must not move for a certain period of time. In addition, most of the remaining fingers can not be worked on, since the clamp placed on a finger is very capacious and prevents further treatment of the other fingers.

Based on this prior art, therefore, the task is to provide a Pinch- or fingernail clamp available that sits on the one hand safely on the finger, even if the customer moves his fingers, and on the other hand allows the nail designer to work on the other fingers without this work being disturbed by the fingernail clamps on one or more fingers.

This object is achieved by a fingernail clamp with a tubular clamping body, a spacer tube and a ring, wherein the tubular clamping body has two longitudinally extending, convex-concave in cross-section leg and extend between the legs longitudinal slots, wherein the legs at the first end the fingernail clamp are held together while the legs are exposed at the second end of the fingernail clamp, the legs becoming narrower towards the second end of the fingernail clamp on at least one longitudinal side so that the longitudinal slot on at least one longitudinal side of the clamp body toward the second end of the fingernail clamp widened a recess, and in the interior of the clamp body, a spacer tube extends in the longitudinal direction, which is set in the interior of the clamp body and terminates at the second end of the fingernail clamp in front of the clamp body, wherein on the clamp body a längsve rschieblicher ring is that compresses the legs of the clamp body when moving in the direction of the second end of the fingernail clamp.

With the aid of the fingernail clamp according to the invention, a substantially tubular pinch clamp is provided which sits very reliably on the finger and practically does not slide off the finger without releasing the ring can. In addition, it is ensured by the tubular design that a finger with attached fingernail clamp ultimately behaves like an oversized finger extended, the work on the other fingers is practically not hindered. When placing the fingernail clamp, the side with the recess is placed on the fingernail, ie the narrowing sides of the legs, which form the recess, adjoin the fingernail. The legs of the clamp body thus lie in the edge region of the fingernail and press the side lines of the nail together and the fingernail in a more curved shape. The recess in the clamping body ensures that the legs can extend over a certain length of the fingernail, without the finger itself, ie the finger bale is crushed. The spacer tube serves as a stop and determines how far the finger nail clamp can be pushed onto the finger. In addition, the spacer tube is also important for the shaping of the fingernail, as this determines the curvature of the fingernail. The spacer tube thus has a double function. When pushing the fingernail clamp, the ring is initially at the first end of the fingernail clamp, ie the end at which the ends of the clamp body are held together, so that the legs of the clamp body can be pushed onto the fingernail without much resistance. Subsequently, the ring is moved in the direction of the second end of the fingernail clamp, in order in this way to compress the free ends of the legs of the clamp body and to achieve a fixation of the fingernail clamp. The ring is pushed so far that on the one hand sufficient fixation of the fingernail clamp is brought about, on the other hand, however, the customer no pain.

The width of the legs decreases towards the second end of the fingernail clamp on the axis, which corresponds to the connecting line between the longitudinal slots, ie orthogonal to the longitudinal direction of the clamp body. The legs are curved convex-concave, with the concave sides facing each other, so that extends between the legs on both sides of a longitudinal slot.

Since the spacer tube runs in the interior of the clamp body, the diameter of the spacer tube must be slightly smaller than that of the clamp body. At the same time, the outer diameter of the spacer tube can correspond to the inner diameter of the clamping body. On the clamp body in turn is the longitudinally displaceable ring whose inner diameter should be slightly smaller than the outer diameter of the clamp body at least in the region of the second end of the finger nail clamp in order to bring about a clamping effect by moving the ring can.

Typically, in the area of narrowing, the legs are rounded towards the second end of the fingernail clamp, i. H. the legs become largely uniformly narrower toward the second end of the fingernail clamp and eventually terminate in very narrow ends of the legs. Over a majority of the length of the clamp body, the legs are usually uniformly wide, d. H. constant in cross-section, only at the second end, the legs are narrower. While the legs are convex-concave in the region of the first end of the fingernail clamp as well as in the middle region, so that the overall result is a tubular shape of the clamping body with longitudinal slots, the legs are usually only slightly curved in the region of the second end of the fingernail clamp.

In addition, the legs at the second end of the fingernail clamp on the side facing the recess may have a step through which the legs at the outermost end of the second end are still a little narrower. This ensures that the skin is not squeezed or injured in the area of the nail wall at the root of the fingernail.

For the production of the fingernail clamp, in particular of the clamping body and the spacer tube, different materials are conceivable. The preparation is preferably made of aluminum, in particular anodized aluminum. The slidable ring can also be made of aluminum, but is often made of a plastic, such as polyoxymethylene (POM). Of course, it is also possible to make the fingernail clamp from other materials, such as stainless steel or in a cheaper version completely made of plastic.

In order to achieve a good clamping effect, it is advantageous if the diameter of the clamping body increases slightly from the first end to the second end, in which case the clamping body is considered to be at rest, ie. H. without displacement of the ring in the direction of the second end. The longitudinally displaceable ring, therefore, when clamping from a region in which the ring can be easily moved, pushed toward a region in which a clamping is generated. The diameter of the clamp body can therefore be slightly smaller in the region of the first end, in the region of the second end, however, be slightly larger than the inner diameter of the ring, so that the legs are pressed together upon displacement of the ring in the direction of the second end, when displaced in the direction of the first end, however, spring apart again. The latter allows for easy removal of the fingernail clamp from the finger after the pinch process is completed. In addition, prevents an outer diameter of the clamping body in the region of the second end, which is slightly larger than the inner diameter of the ring, that the ring when not in use from the terminal body drops or can be deducted at all.

Advantageously, moreover, the first end of the fingernail clamp, i. H. the region where the legs are held together has an enlarged diameter portion which prevents the ring from peeling over the first end of the fingernail clamp. In this area may thus be a slight thickening.

In the area of the first end of the fingernail clamp, the spacer tube is usually fixed to the fingernail clamp, using conventional joining techniques, such as welding, soldering, gluing or screwing. In the legs of the clamp body may be components of a tube, in which longitudinal slots are milled on both sides, but it can also be completely free leg, which are held together only in the region of the first end of the fingernail clamp so that the two Overall convex-concave legs generally result in the shape of a tube with longitudinal slots.

As already mentioned, the legs must be narrower, at least on one side, so that a recess is formed on at least one longitudinal side of the clamping body. However, it is also possible for the legs to become narrower on both longitudinal sides to the second end of the fingernail clamp, so that the longitudinal slots on both longitudinal sides of the clamp body widen in the direction of the second end to form recesses. In this way, the flexibility of the fingernail clamp is further increased and the handling improved.

The spacer tube terminates before the second end of the fingernail clamp, i. H. extends less far toward the second end than the legs. The length adjustment must be made so that the spacer tube ends at the finger ball, while the ends of the legs extend over the fingernail itself. For the fingers and fingernails of different customers and the different types of fingers (index finger, middle finger, ring finger, little finger and thumb) therefore different fingernail clamps can be kept in which the diameter, the curvature of the legs and the configuration of the recess in the clamp body can differ. About the curvature of the spacer tube and the curvature of the fingernail is also determined, d. H. Depending on the desired curvature, fingernail clamps with different spacer tubes can be used.

The individual dimensions are adapted to the different fingers of the generally female customers and therefore may vary slightly in their dimensions. In addition, the curvature of the clamp body and the spacer tube also vary depending on the desired Pinch result, so if a very strong curvature of the fingernail is desired, the curvature must be stronger at the fingernail clamp and vice versa. Typically, the entire finger nail clamp has a length in the range between 50 and 70 mm, wherein the actual leg length can be between 40 and 60 mm. The recess is about as long as a typical fingernail, for example, about 12 to 18 mm.

The outer diameter of the clamping body may increase from the first end to the second end, so that the displacement of the ring in the direction of the second end is always heavier, in order to achieve the desired clamping effect. Typical outer diameter of the clamping body in the range of smaller diameter are therefore 11 to 13 mm, in the range of the larger diameter 12.5 to 14.5 mm. Also, the inner diameter of the longitudinally displaceable ring should be tuned to this and be for example about 12 to 13 mm. In this way, a displacement of the ring in the region of the first end of the fingernail clamp is easy, in the region of the second end, however, difficult. The outer diameter of the longitudinally different ring is less critical, but should be taken to a good gripping and handling. A typical outer diameter is therefore in the range of 16 to 20 mm.

The spacer tube has a length that extends with attached fingernail clamp to the finger. Typically, the length is 30 to 50 mm. The spacer tube ends at the second end a few millimeters in front of the legs of the clamp body, typically 2 to 8 mm. The outer diameter may for example be 6 to 8 mm, so that the spacer tube is easily accommodate in the clamp body. The inner diameter of the spacer tube is for example 4 to 6 mm, taking care that no too sharp edge is formed, which could feel the customer as unpleasant.

In order to increase the wearing comfort further, individual or all edges of the fingernail clamp can be chamfered, so that as far as possible no sharp transitions result.

The invention will be explained in more detail with reference to the accompanying figures.

In FIG. 1 the fingernail or pinch clamp according to the invention is shown in a side view. It comprises the clamping body 1, which is composed essentially of two legs 4, which are held together at the first end 6 of the fingernail clamp and are free at the second end 7. Towards the second end 7, the legs 4 become narrower and form a recess 8 into which the fingertip is introduced when pinching. Within the clamp body 1 extends a spacer tube 2, which acts as a kind of stop for the fingertip and is shown in dashed lines. In addition, the spacer tube 2 is partly responsible for the curvature of the fingernail. The located on the clamp body 1 ring 3 is longitudinally displaceable according to the arrow 9. At the first end 6 of the fingernail clamp, slipping or pulling off of the ring 3 is prevented by an enlarged diameter portion 11. At the second end 7, the clamping body 1 has a step 10, which prevents the skin from being squeezed in the area of the nail wall at the root of the fingernail.

In FIG. 2 the fingernail clamp is shown in plan view, wherein the spacer tube 2 has been omitted for clarity. It can be seen that the clamping body 1 consists of two legs 4, between which a longitudinal slot 5 extends. In the direction of the second end 7, the longitudinal slot 5 widens to a recess 8, by the legs 4 significantly narrower become. The ring 3 is in the rest position, ie the clamping action of the fingernail clamp is the smallest here, so that the fingernail clamp can be attached to a finger.

In FIG. 3 is the fingernail clamp in the front view according to the section AA Fig. 2 shown. The legs 4 are curved convex-concave, with the concave sides facing each other and extends between the legs 4 on both sides of a longitudinal slot 5.

The FIG. 4 equals to FIG. 2 However, here is the located in the interior of the clamp body 1, extending in the longitudinal direction spacer tube 2 shown. The spacer tube 2 serves as a stop for the fingertip and limits the advancement of the fingernail clamp and specifies the curvature of the fingernail.

The FIG. 5 shows the fingernail clamp FIG. 4 , However, with shifted in the direction of the second end 7 ring 3. In this way, the legs 4 of the clamp body 1 are pressed together and achieved a clamping effect. The ring 3 is moved so far in the direction of the second end 7, that on the one hand, the fingernail clamp is held securely on the finger, on the other hand, however, the customer no pain.
