DE202015002851U1 - Screwless hinge for spectacle frames with (click effect) - Google Patents

Abstract

Screw-free hinge for spectacle frames with "click effect" This is characterized in that at the end of the jaw (joint area) are two tongues (1a) which are bent (1b)) to act as a plug holder for the bolt.

Description

The subject of the invention is a screwless spectacle frame with "click effect". A bolt with a groove is attached to the front of the eyeglass frame (cheek). The earloop is then clicked into the groove of the bolt. The circumferential groove then allows the insertion of the earhook inwards.

State of the art

In the main, the glasses hinges consist of 2 or 3 legs running into each other, which are connected by a screw and at the same time connect to the front glasses and earhook. The mounting options are versatile but also expensive just like the production of the hinges. Only a few innovative solutions are screwless and represent the connection between the front of the glasses and the earhook, which uses different bending techniques. In the DE 20 2011 108 421 U1 a spectacle hinge is described in which the temple is connected via a rotation axis with the spectacle frame and can be by means of a pivoting movement about the axis of rotation and fold out. The bracket is provided in the region of the joint with a clamping element which partially surrounds the axis of rotation and has a connecting web to the adjacent bracket. In the DE 20 2008 011 154 U1 is described an elastic spectacle frame in which an elastic, consisting of two flat elements hinge is provided with a slot for receiving a resilient member and a bolt. The element has a stopper and both elements are rotatably coupled by a connecting element. In the DE 20 2012 005 914 U1 is described a screwless spectacle hinge comprising a hinge block and a temple, wherein the temple is mounted in the hinge block. The hinge block has a recess and a guide channel. The spectacle hinge has a male element which is arranged in the recess. The eyeglass temple has a temple extension which is connected to the male element, wherein the temple extension is arranged in the guide channel with the hinge folded out.

The aforementioned solutions have the following disadvantages. The hinge solutions also require functional elements. These are predominantly one or more elements that need to be manufactured consuming and precisely fitted. The attachment of these elements is very different, always with additional additional components such. B. positioning devices or clamping elements must be worked.

The subject of the application relates mainly to the connection jaw / earloop and is mainly used in rimless eyeglass frames. The jaw itself, can be used in its continuation quite as a full rim, - Nylorfassung in the metal or plastic sector.

The object of the present invention is to guarantee a durable and in their movement a smooth ironing gear with little effort without additional soldering or welding. The assembly is easy and can be done on different materials.

The object of the invention is achieved as follows:
At the end of the cheek (joint area) there are two tongues ( 1a ) which are bent ( 1b ) to act as a plug-in bracket for the bolt.

The bolt ( 2 ) has a circumferential groove, this corresponds in diameter to the hook. The width of the groove corresponds to the material thickness of the earhook. The precise adjustment between the bolt and the earhook controls and guarantees the earloop.

The earhook ( 3 ) shows a pronounced hook with an expiring approach, this prevents the rollover of the earhook.

The assembly of the 3 components is very simple and uncomplicated. It is possible to connect different materials with each other via the bolt.

The solution according to the invention has the following advantages:
The assembly of the 3 components is very simple and uncomplicated. It is possible to connect different materials with each other via the bolt. There is no need to perform additional welding or soldering and no complex assembly work is necessary. A big advantage is the small amount of time needed to connect the earhook and jaw.

Hereinafter, an embodiment of the invention "Schraulosen hinge" is described in detail with reference to drawings. Based on 3 embodiments ( 1 - 3 ) is a schematic diagram of the inventive screwless hinge for spectacle frames with "click effect" shown.
