Abstract

A finger or toe nail lengthening process and device are disclosed. A lengthening mould is set on the nail, then an artificial extension of the nail is formed by simultaneously applying layer after layer of a hardenable resin coating on the nail and mould. The artificial extension is hardened and then detached from the mould. At least one layer of hardenable resin is applied by means of a profiled template (20, 21) and/or the profiled template is restrained at a distance above the mould (1).

description

The invention relates to a method for the extension of fingernails or toenails, in which a form of extension is applied to the nail and then an artificial extension is formed in layers by jointly coating the nail and form with a hardenable resin, which hardens and then from the Form is replaced.

In addition, the invention relates to a device for the extension of fingernails or toenails, with a form of extension.

The object of the invention is to facilitate the manual extension of the fingernails and to improve the quality of the extended nail.

In a generic method, this object is achieved in that at least one layer is applied by means of a profiled template. The profile of the template is adapted to the profile of the shape. This gives the extended part of the nail a uniform layer thickness. The number of layers to be applied can be reduced, which makes work considerably easier. The end result is essentially independent of manual skill.

In an embodiment of the invention it is provided that the profiled template is positively guided at a distance above the mold. As a result, a certain layer thickness is forcibly applied. One or two layers are usually sufficient to extend the nail.

In a further embodiment of the invention it is provided that a first opaque, preferably white layer is applied with a first profiled template. This layer corresponds to the nail white.

The extended part has a particularly natural effect when a second, preferably transparent, layer is applied to the first layer is applied with a second profiled template. The profile of this second template is set slightly higher by the intended layer thickness.

The layers can harden particularly quickly if the layers are hardened by irradiation with UV light.

Because a suitable separating layer, preferably a silicone oil, is applied to the mold, the release of the extension from the mold also presents no problems.

In addition, provision can be made for the removal to take place by compressed air and / or vacuum.

The device task is solved in a device for the extension of fingernails or toenails with a shape of the extension in that the shape is assigned a profiled template, with guides being provided on the shape and / or template, which have an approximately constant distance between the shape and the template pretend. This means that with a single application, a layer thickness is applied that corresponds to the distance and, after curing, results in the extended fingernail. The usual repeated layer-by-layer application with a brush can thus be avoided. In addition, the time-consuming reworking and filing of the fingernails into the final shape is reduced. Only the edges and the front end need to be reworked slightly.

In an embodiment of the invention it is provided that the guide is designed as a parallel profile on the mold. Such a device can be brought directly onto the surface of the mold, for example in the form of simple strips. The strips border the later extended fingernail and specify the layer thickness with their height. When applying the layer, the template is then supported on the profile, so that there is a constant distance from the surface of the mold. Of course, the template must have approximately the same curvature in the transverse direction as the shape itself. The execution of the guide as a parallel profile can also be so be realized that the guide is designed as a shoulder to the side of the shape.

For simpler applications, e.g. when using known extension forms, in which there are no strips on the surface of the form, it is sufficient if the guide is designed as form elements, in particular elevations, on the template. However, the lack of longitudinal guidance requires greater manual dexterity in order to achieve a straight fingernail extension.

This disadvantage can be avoided if the template has shaped elements that are adapted to the profile of the shape. This results in a forced guidance of the template on the mold.

The application of the layer is facilitated in that the template is connected to a container, preferably a tube, as a storage container for nail-forming plastic. The template with its outflow opening can be provided with an internal thread into which the protruding thread of a tube can be screwed. After the order has been completed, the tube can be closed again with a screw cap. It is particularly advantageous if the content of the tube is dimensioned such that the tube is sufficient for processing both hands. For hygienic reasons, a single use is recommended. In this way, a constant quality of the extended nail can be achieved. The mass to be applied is then advantageously fresh each time.

Since two different components of a synthetic resin composition are usually used for the layer formation, it is particularly advantageous if two stencils and containers are connected to form a handling unit. The two templates are also contoured differently so that the layer can be adapted to the shape of the moon of a fingernail when applied.

The fact that several shapes are arranged on a common plate, all fingernails can simultaneously processed and then cured together under UV radiation, which saves a considerable amount of time.

Adaptation to different hand shapes is particularly easy if the shapes are attached to the plate using magnets or Velcro elements.

During the application and curing phase, the hand is comfortably bedded in that the plate has a pad. Since displacements of the fingers easily result in a parting line between the natural fingernail and the extension, which can lead to later tearing off of the extended fingernail, it is provided that clamping elements are assigned to each shape. The shape is thus immovably connected to the finger, so that the work result always achieves a consistently high level of quality.

The fixing of the hand can also be achieved particularly simply in that the support pad is made inflatable. Under a fixed belt, the hand can be pressed against the belt by inflating the cushion and a firm fit can be achieved in this way.

Alternatively or in connection with individual tensioning elements, it can also be provided that at least one tensioning element for fixing the hand or fingers is assigned to a plate. As tensioning elements, for example, bands or loops can be considered, which can be adapted to the fingers of the hand with known tensioning elements.

Alternatively or in addition, it can also be provided that the tensioning element is designed to be inflatable.

The shape becomes particularly light if it is designed as surfaces curved in two directions in the form of a thin layer, the shape of which is predetermined by frames.

Detaching the nail from the mold is facilitated if the mold is flexible, preferably by weakening of frames. The ribs can be weakened, for example, in the form of arbitrarily provided slots.

A smooth transition between natural and artificial nail can be achieved in that the mold has shaped elements for fixing the nail and in a further embodiment the holder is assigned to the mold, preferably with a bed for the nail-bearing member. In this way, the finger with nail is fixed immovably for the processing time.

If the shape in the holder is interchangeable, one holder is sufficient for a whole set of different shapes.

Any deposits of resin on the template can be easily removed if the template is made of flexible material, preferably a silicone rubber.

The extension can be easily detached from the mold by the mold being made of Teflon or a polyethylene.

It is further provided for curing that a switchable UV light source is provided in the holder.

The extension detaches itself more easily from the mold if the mold has a mold release, which is preferably designed as an inflatable membrane.

The extension can be better adapted to the desired shape in its end regions if the template has an additional contour transverse to its profile. The additional contour can then be adapted to the natural shape of the nail moon, for example.

The layer thicknesses can be individually adjusted as desired if the guide part and / or the guide is adjustable.

The invention is described in a preferred embodiment with reference to a drawing, with further advantageous details relating to the figures of the drawing

In Fig. 1, 1 denotes the shape, the surface 2 of which is curved both in the direction of the finger and transversely thereto. An opening 3 nestles in an elliptically shaped area 4 against the front contour of the natural fingernail, the natural fingernail extending somewhat beyond the contour 4 is supported on the surface 2 of the mold 1. To the side of the opening 3 run two ledges 5. The height of the ledges 5, with which they protrude above the surface 2 of the mold 1, determines the subsequent layer thickness of the artificial fingernail, provided that a stencil guided over it has the same curvature as the surface 2 of the Form 1 has.

The curvature of the surface 2 can be predetermined, for example, by a frame 6 indicated in broken lines. A band 7 wraps around the front of the fingertip on one side and is guided through channels 8 formed in the side of the mold 1. By tightening one end 9, the shape can be clamped on the tip of the finger 10. In this way, the natural fingernail 11 can no longer move relative to the surface 2 of the mold 1. Starting from the moon 12 of the natural fingernail 10, a layer covering the shape and the fingernail 11 can thus be applied.

Fig. 2 shows a section according to arrow II-II in Fig. 1. The curvature of the surface 2 is shown as it is given by the frame 6. Frame 6 is weakened by slot 13. As a result, the surface of the mold 1 can be compressed laterally somewhat after the fingernail extension has hardened, which facilitates the detachment of the artificial fingernail that extends between the bordering strips 5.

Fig. 3 shows a plate 14 on which five molds 1, namely for each finger of the right hand are arranged. The shape 15 is adapted accordingly to the position of the thumb. The plate 14 shown in Fig. 3 is intended for the right hand. The corresponding plate for the left hand is formed in mirror image.

A support pad 16 is provided approximately in the center for more convenient storage and additional fixation of the hand. So that the fingers can not be moved during curing, a band 17 is used to hold the hand between the pad 16 and Clamp volume 17. For this purpose, the pad 16 is inflatable.

A section through the plate according to arrows IV-IV in FIG. 3 is shown in FIG. 4. The hand, not shown for a better overview, is thus taken up between the support pad 16 and the band 17. The fingers extend in the cavity formed by Form 1. In addition, this illustration shows a further frame 18 which extends in the direction of the finger and which determines the curvature in the direction of the finger for the surface 2 of the mold 1. Form 1 is firmly connected to a magnet 19 which holds the form 1 on the ferromagnetic plate 14. After overcoming the magnetic force between the plate 14 and the magnet 19, the position of the mold 1 can be adapted to the individual hand.

However, it is more pleasant if the plate 14 has a velor-like surface and, for example, a Velcro element is provided instead of a magnet.

Templates as shown in Fig. 5 are used to apply the resin components. FIG. 5 shows a first template 20 and a second template 21 which, as shown in FIG. 6, are screwed onto a first 22 and a second 23 tube, respectively. The curvature 24 or 25 of the stencils 20, 21 corresponds approximately to the curvature of the surface of the mold 1. At the edge of the stencils, shaped elements 26 are arranged, the height of which determines the layer thickness. From the interior of the tubes 22, 23, the contents reach the curved surface via channels 27, 28, the distance of which from the surface 2 of the mold 1 then gives the resulting layer thickness.

For the first order, a template contoured according to FIG. 7 is used, so that the moon of the natural fingernail is released. The contour of the first template 20 results from FIG. 7. A second template is then used for the subsequent second layer application, the contour of which results from FIG. 8 and also covers the moon 12 of the fingernail 11.

FIG. 9 shows the situation when applying the first layer. The strips 5 determine the distance of the template 20 from the surface 2 of the mold 1. In addition, the strips 5 guide the template 20 because the distance between the molded elements 26 depends on the distance the strips 5 are matched. This results in a movement which is positively guided in the longitudinal direction and in which there is a constant distance between the template 20 and the surface of the mold 1.

The second template 21 is designed so that there is a greater distance from the natural fingernail. This creates a sufficient distance from the first applied layer, which then determines the thickness of the second applied layer in an analogous manner.

A further embodiment of the invention is shown in FIG. 10. The shape 101 is designated, the surface 102 of which determines the shape of the nail extension. A guide 103 is firmly connected to the mold 101, the track 104 of which is adapted to the longitudinal profile of the mold. Mold 101 and guide 103 thus form a coherent part with a front rear grip 105, which can be inserted into a corresponding recess 106 in a holder 107.

Bracket 107 has a groove 108 which serves as a bed for a finger to be inserted. Together with a recess 110 in the form 101, a cavity is formed with an upper edge 109, which determines the end position of the fingertip, the edge 109 supporting and fixing the nail end.

The template 111 is guided with its profile 112 at a distance 113 along the surface 102 of the mold 101. The shoulder part 11-4 of the template 111, which is designed as a shoulder, is supported on the guide 101, more precisely the guide track 104.

REPLACEMENT SHEET (REGEL26i) 1 0

At the same time, resin can flow out of a container 115 through opening 116 onto the surface 102 of the mold 101. The distance 113 resulting from the positive guidance of the guide part 114 and guide track 104 determines the thickness of the layer that is formed.

In FIG. 13 it can be seen that the template has an additional contour 117 transversely to the plane of its profile 112. Their shape is designed so that there is a natural appearance of the extension in the end areas. For example, the contour can be adapted to the moon of a fingernail.

Different shapes can be used in a holder 107, which are adapted, for example, to the individual fingers of the human hand.

The layer thickness is adjusted by changing the position of the shoulder 114, which can be done, for example, by means of a set screw provided.
