Description

The invention relates to a screwless spectacle hinge comprising a hinge block and a temple, wherein the temple is attached to the hinge block and a spectacle frame comprising the screwless hinge according to the invention.

Eyeglass frames usually have a frame and two eyeglass temples hinged to the frame. The temples are attached to the frame so that they can be folded on the frame for better transport and storage of the glasses. For this purpose, the eyeglass temple on a hinge. In most eyeglasses, this hinge consists of a variety of filigree parts, often the bracket is fixed by a screw on the frame. Due to the large number of parts, the production of the hinges is relatively complex and therefore associated with higher costs. There are therefore efforts to make eyeglass hinges easier.

The DE 198 35 386 C1 describes a spectacle hinge, wherein the bracket and the spectacle frame are connected to each other via a hinge block. The temple is attached via an extension on the hinge block, which is ensured by bending the tail of the extension that the temple is permanently attached to the frame. However, this hinge has the disadvantage that it allows only slight variation possibilities with regard to the design of the spectacle frame and in particular of the spectacle arm.

The EP 0 945 751 A1 describes a spectacle hinge in which the eyeglass temple is firmly connected to the male element. The male member and the hinge block are rotatably connected to each other. When folding or folding a corresponding pair of spectacles, the temples and insert element rotate as a unit.

EP 1 126 308 A1 discloses a screwless eyeglass hinge in which a male member is first inserted into a bearing housing and in a second step, the eyeglass temple is pulled by male member and bearing housing. The temple is firmly connected to the male element.

Also DE 44 21 309 C1 describes a spectacle hinge, is mounted in the hinge element in a receiving element. Joint element and receiving element are coupled without other connecting parts, so that an easy assembly and disassembly is possible.

US 2005/0225717 A1 discloses a spectacle hinge in which a round male member is mounted on the temple piece in a hinge block on the spectacle frame. The round element rotates in the hinge block and thereby moves the eyeglass temple.

A similar eyeglass hinge revealed WO 2006/136932 A1 , The eyeglass hinge is also designed without screws, small parts or solder joints. To guide the eyeglass temple, a rotating cylinder is mounted in a block in the spectacle frame.

Object of the present invention is therefore to provide a spectacle hinge that does not have the disadvantages mentioned above, with little effort to assemble, is low in production and is less susceptible to interference due to its design. In addition, it should allow the use of different materials and different optical configurations of the spectacle frame.

The object is achieved by a screwless spectacle hinge according to claim 1.

The spectacle hinge according to the invention comprises a hinge block and a temple, wherein the temple is attached to the hinge block. The hinge block of the spectacle hinge according to the invention has a recess and a guide channel. The recess preferably extends over the entire width of the hinge block, so that a hole is formed in the hinge block. The guide channel is arranged on the side facing the eyeglass frame inwards. The eyeglass hinge includes a male member disposed in the recess. About a temple extension of the temple piece is connected to the male element, wherein the temple extension is arranged in the guide channel with hinged hinge. The male member has an insertion opening in which one end of the temple extension is arranged and the temple extension is rotatably mounted in the insertion opening.

Further embodiments are the subject matter of the subclaims or described below.

The spectacle hinge according to the invention preferably consists only of the three components hinge block, male and ironing process. Due to the small number of components, the assembly effort is very low, so that a cost-effective production is possible.

The temple extension is preferably a wire, for example a metal wire, which is bent over at one end, preferably at right angles. The bent end of the temple extension is attached to the male element. The male member has an insertion opening in which the ironing process is arranged. In a round wire as ironing process, the insertion of the male is correspondingly a cylindrical opening. The bent end of the temple extension is arranged in the male member, while the straight end of the temple extension is arranged in the guide channel of the hinge block with the hinge folded. By the guide channel, the mobility or slipping of the temple extension is prevented in the vertical direction, since the temple extension can be moved maximum extent that it touches the upper wall of the guide channel.

The male member is preferably positively connected to the hinge block. The male element may have different shapes, with male elements having a round, oval, rectangular, triangular, polygonal, star-shaped or heart-shaped base area being preferred. Particularly preferably, the male member is a round or oval disc or a rectangular, triangular or polygonal plate. The male member is preferably the same width as the hinge block and, if desired for optical reasons, may be narrower than the hinge block or wider than the hinge block so as to protrude therefrom.

The construction of the spectacle hinge according to the invention makes it possible to design the spectacle hinge of any materials. Thus, the male member is preferably constructed of wood, metal, plastic, horn or a combination of different materials, as well as the hinge block is constructed of wood, metal, horn, plastic or a combination of these materials. It is possible to use male element and hinge block made of the same material or different materials. This is another advantage of the eyeglass hinge according to the invention that allows adaptation to the material used for optical or technical reasons. In addition, the use of different materials also allows the possibility of different shapes for the male and a large variety of designs.

The hinge block also preferably has a second recess for receiving the spectacle frame. The frame, for example, in the form of a metal frame or in the form of a carbon plate is then placed in these two recesses. The second recess is placed in the hinge block at the end opposite the guide channel. The guide channel extends from the second recess, in which the male member is placed, to the edge of the hinge block.

The temple extension, to which the temple is attached, lies in the unfolded state in this guide channel and protrudes with its one end out of the hinge block. The temple extension is either formed integrally with the eyeglass temple or designed as a component to which the eyeglass temple is attached. This depends essentially on the design of the eyeglass temple. If a simple metal strap is used, the temple extension and the temple are preferably formed in one piece. In a temples made of plastic or wood, the temple is preferably connected to these as a component.

The eyeglass hinge according to the invention is thus screwless, there are no additional bolts or other fasteners necessary to attach the eyeglass temple to the hinge block. The spectacle frame can be inserted into the spectacle hinge, glued to it or otherwise connected. In one embodiment, the hinge block and the spectacle frame are integrally formed.

For mounting the eyeglass hinge according to the invention only two assembly steps are necessary. In a first step, the temple extension is inserted into the corresponding opening of the male member. The ironing process is then rotatably mounted in this opening. In the second assembly step, the male element is inserted with buckle extension in the hinge block. The male member may be additionally fixed in the hinge block by gluing or other conventional fasteners, but this is less preferred according to the invention.

The invention furthermore relates to a spectacle frame comprising two temples, a spectacle frame and two screwless hinges according to the invention. The screwless hinges have the embodiment described above. The invention will be explained in more detail with reference to the following figures. Show it
