Description

Sash for gemstone

The invention relates to a socket for a gemstone for attachment in a recess of a carrier body having an opening having a setting part, in which the gemstone can be arranged and a holding part, which can be arranged in the recess of the carrier body.

For ornamentation of everyday objects gemstones are often used, the gems are held by versions, which in turn are attached in or on the relevant everyday object.

A socket for fixing a gemstone is shown in EP 0 888 731 A2, wherein the socket consists of an annularly bent band which is arranged in a through hole of a thin-walled carrier. The disadvantage of this version is that thereby attachment of gemstones is possible only on everyday objects that have a thin-walled carrier. Use with other everyday objects is not possible. A further version for gemstones is shown in EP 0 346 698 A1, wherein this socket comprises a metallic ring which can be inserted into a carrier and fixed by means of holding tongues arranged on the outside of the ring. The attachment of the gem in the socket is realized by bending over arranged at the top of the ring holding elements. These holding elements are e.g. claw-shaped. The disadvantage of this version is that the attachment of the gems in the version is cumbersome. In addition, due to the retaining tongues, the outer wall of the ring is not flat against the opening of the carrier, whereby dirt can penetrate into the recess of the carrier and damage the socket made of metal, for example due to corrosion.

Another gemstone mount shows the French patent application FR 2 849 356. The versions have different types of devices with which an attachment in a carrier body is possible. The disadvantage is the additional effort for the production of the fastening devices, which are always associated with a certain error rate.

The US 2009/0229307 shows a version for the decoration of utility objects with gemstones, wherein in a completely cylindrical socket a gemstone is used, which is held with three metallic brackets.

JP 2003-88408 shows a socket for gemstones for arrangement in a carrier body. The gemstone is inserted from below into the socket until it is held by a circular projection. Subsequently, a holding plate is tracked from below, having notches, wherein arranged on the socket holding elements for fixing the holding plate are inserted into the notches and then bent. This method of fixing gemstones is cumbersome and associated with a lot of effort.

The object of the invention is to provide a socket for a gemstone available, which avoids the above disadvantages and allows a simple arrangement and attachment of the gemstone in the socket.

This is achieved by a socket with the features of claim 1.

The version according to the invention serves for fastening a gemstone in a recess of a carrier body. The carrier body can be any everyday object, such as a housing for a mobile phone, furniture or other furnishings, watches, spectacle frames or other fashion accessories, household electronic appliances, components of a car interior, decorative ornaments and the like. The material of the carrier body is arbitrary in itself. In particular, it may be carrier body made of plastic or metal.

The socket has an opening having a setting part in which the gemstone can be arranged and fastened. Furthermore, a holding part is provided, which can be arranged in the recess of the carrier body. In this case, an arrangement in thick-walled carrier bodies is possible. By now provided that the setting part is elastic and the opening of the setting part is partially provided with projections into which the gemstone is clipped, a particularly simple arrangement and fixation of the gemstone in the socket is possible. The setting part with the projections forms as a result of the elastic setting part a mechanical latching connection for the gemstone by the restoring force of the elastic setting part acts on the gemstone, since the gemstone pushes apart the opening of the setting part at least during insertion. The holding part of the socket can be arranged in any carrier bodies with a correspondingly formed recess. For example, the holding part can be pressed into a recess provided with a corresponding size, whereby the attachment takes place by means of a frictional connection. It may also be provided that the holding part is glued into the recess, wherein the adhesive to be used is selected depending on the material of the holding part and the carrier body under known per se in the prior art adhesives.

The projections, which are arranged in regions of the opening of the setting part, are preferably arranged at the upper edge of the opening of the setting part remote from the holding part and point towards the center of the opening. The projections are designed such that a secure attachment of the gemstone is guaranteed.

By the outer wall of the holding part is at least partially conical, insertion of the socket into the recess of the carrier body by the smaller on the underside of the holding part cross-sectional diameter is particularly easy. With suitable dimensions of the recess in the carrier body, the socket is clamped in the recess and frictionally held in the carrier body as a result of increasing in the direction of the setting part cross-sectional diameter of the socket. The conicity of the outer wall of the holding part means that the holding part is tapered in the direction away from the setting part direction. The opening angle of the conical region is kept low. Due to the shape of the holding part can be dispensed with further complicated devices for fixing the socket. It may be provided that the holding part is not only partially provided with a conical outer wall, but conical over its entire length is trained. The conicity of the outer wall can be achieved for example by a holding part in the form of a rotary truncated cone. The conical region is preferably that region of the holding part which rests in the recess of the carrier body in the inserted state of the holder.

In the version according to the invention attachable gemstones can consist of any materials in principle. The invention can be used both for glass stones and for natural or synthetic precious and semi-precious stones, wherein the gemstones can be ground facetted. In particular, the invention for gemstones having a Rondiste, so for example for Chatons usable. The opening of the setting part forms the edge of a recess in the setting part, in which the gemstone can be arranged. This recess may be formed depending on the gemstone to be fastened in the socket. Further advantageous embodiments of the invention are defined in the dependent claims.

In one embodiment of the invention, the projections of the setting part engage behind the gem in the state arranged in the socket. The projections are arranged as an undercut in the region of the opening of the setting part.

In a further embodiment of the invention, the opening along an entire circumferential line is provided with projections, whereby the holding action is improved for the gemstone arranged in the socket. This circumferential line is preferably the outer edge of the opening. The opening itself is circular in one embodiment of the invention.

In one embodiment of the invention, the setting part and the projections on such dimensions that the gemstone is held in a form-fitting manner in the set part in the version arranged in the socket.

In a further embodiment of the invention, the setting part and the projections on such dimensions that the gemstone is held frictionally in the setting part in the mounted state in the setting part. In particular, a positive connection supported by a traction is also conceivable. The frictional connection can arise by friction, since the elastically formed setting part spring-loaded by the restoring force of the setting part of the gem, if the dimensions of the setting part and the Projections and the inserted gemstone are selected accordingly. The restoring force of the setting part acts in this case on the gem used in the setting part. The advantage of such a holder of the gem is that the gemstone is held as free of play in the socket, whereby an unintentional removal of the gemstone is avoided from the socket. It can be provided to additionally support the connection between gemstone and socket with an adhesive.

In a preferred embodiment of the invention, the setting part and additionally or alternatively the holding part consists essentially of a preferably thermoplastic material. Compared to the known in the prior art versions of metal sockets that are partially or completely made of plastic, have many advantages. In particular, such sockets have a lower weight and are less affected by external environmental influences, whereas metallic sockets tend to corrosion. In addition, plastic sockets are particularly easy to produce in large quantities by injection molding and offer in terms of shape and color of the socket extremely flexible and versatile options. In addition, such versions are cheaper to produce than metal frames, if high demands are placed on the metal in terms of aesthetic impression. In addition, such versions can ensure the necessary elasticity of the set by a suitable plastic.

In order to arrange the holding part, for example by gluing in a recess of a carrier body, adhesives are used in this case, with which a plastic-containing or made of plastic holding part with the respective carrier body is glued. For the plastic come diverse materials, such as so-called ABS plastics (acrylonitrile-butadiene-styrenes) or PC plastics (polycarbonates) in question, which have the appropriate elasticity. Also polyamides are usable. These plastics can be colored differently, but also be transparent and are particularly suitable as thermoplastic materials for use in injection molding. In addition, ABS plastics are heat-resistant, UV-stable and fire-resistant. Depending on the polycarbonate used, the most varied melting properties can be achieved, depending on the desired field of application. Transparent frames are extremely inconspicuous with respect to the gemstone and thus emphasize the aesthetic impression of the gem, which is arranged in a carrier body. With a colored version additional optical effects can be generated, wherein the color can be selected depending on the color of the carrier body.

In a further embodiment of the invention, the setting part of the socket has an at least partially conical recess for receiving the gemstone. This is particularly advantageous for gems, which have a tip having a set side, which is arranged in the setting part. Such gems are for example Chatons.

The recess in the setting part may be formed as a blind hole. However, it can also be provided that the recess, which has the opening with the projections according to the invention in the set part, is designed as a continuous through hole through the setting part and the holding part, whereby a further weight saving of the socket can be realized. The through hole may also serve to allow the detachment of the gemstone fixed in the setting part by being pushed out of the setting part via the through hole.

In a particularly preferred embodiment of the invention, the setting part and the holding part are formed as a one-piece component. The socket can thus be formed as a one-piece element. In a further preferred embodiment of the invention, the setting part and / or the holding part are rotationally symmetrical. In the case of a rotationally symmetrical holding part while the recess of the support body is also rotationally symmetric and thus easy and inexpensive, for example, produced by a borehole.

The at least partially conical outer surface of the holding member causes this can be used as a wedge in the recess of a support body and thus can be particularly stable held by this. In this case, slight deviations of the conical outer surface may be provided, such as notches or cuts preferably in the longitudinal direction of the Lampholder, whereby the socket can be inserted more easily in a slightly smaller dimensions having recess of a carrier body. In addition, it can be provided, at the end remote from the setting part of the socket, the outer surface of the holding part beveled in the form of a phase in order to enable a simpler insertion into the recess of a carrier body.

In one embodiment of the invention, the outer wall of the holding part is substantially smooth. However, it can also be provided to roughen the holding part on its outer wall, in order to achieve an improved frictional connection, if the holding part is pressed into a recess of a carrier body.

In a preferred embodiment of the invention, the retaining part is formed elastically in addition to the setting part. This is the case, for example, when the holding part and the setting part are formed as a one-piece component. By the elastic holding part compression during insertion into the recess of the carrier body is possible. The elastic effect results in a stable frictional connection.

To facilitate the insertion of the socket in the recess of the carrier body notches and / or longitudinal recesses may be arranged in the holding part. The notches can also be arranged in the longitudinal direction of the socket, whereby a compression of the holding part during the insertion is easier possible. Between the setting part and the holding part of the socket, a notch can be provided on the outer wall. At this recess, the setting part can be supported on the carrier body to prevent further insertion into the carrier body. The invention further relates to a method for producing a gem compound, comprising a carrier body having a recess and a recess arranged in the above-described version, wherein a gem is held in the socket. The gemstone is inserted in the axial direction in the setting part of the socket. The axial direction is formed by the longitudinal direction of the socket. In the case of a rotationally symmetrical version, the axial direction is defined by the axis of rotation. When inserting the gemstone in the axial direction in the set part, the opening of the setting member is first pressed apart. Then grab projections of the opening due to the elastic design of the setting part and the associated restoring force when inserted gem. The holding part of the socket is inserted into the recess of the carrier body, wherein this can be done before or after the insertion of the gem in the setting part.

This method is particularly suitable for gemstones with a Rondiste, such as Chatons. The tip having or at least partially conical trained setting of the gem is first inserted into the set part of the socket. The larger the diameter of the conical region of the setting part of the gemstone, the more the opening of the setting part is pressed apart until the Rondiste is disposed within the recess of the setting part and the diameter of the gem is smaller again. At this point, the projections snap to the opening and hold the gemstone.

In a further embodiment of the method according to the invention, the holding part is glued into the recess of the carrier body.
