Description

Current technical status:

• – randlose Brillengestelle; die Gläser werden mit Bohrungen versehen und die Gestellteile angeschraubt oder eingesteckt.
• – Nylorbrillen; die Gläser werden mit einer umlaufenden Rille versehen und mit einem Nylonfaden festgespannt.
• – Blechbrillen; ähnlich wie bei den Nylorbrillen werden die Gläser mit einer umlaufenden Rille versehen. Der Brillenrahmen wird dann meist an der Bügelseite der Brille geöffnet und mit unterschiedlichen Mechanismen nach einsetzen des Glases geschlossen.
• – Kunststoffbrillen; die Gläser werden mit der sog. Spitzfacette (ca. 120 Grad Winkel) geschliffen und eingesetzt. Der Brillenrahmen wird dazu entweder erwärmt oder die Gläser werden „kalt" eingedrückt.
• – Metallbrillen; die Gläser werden mit Spitzfacette geschliffen. Der Brillenrahmen lässt sich an einer Stelle öffnen und mittels Schraubverbindung wieder schliessen. Die Gläser sitzen mit rel. starker Spannung fest.

For most eyewear frames built to date, the glasses are ground or worked in the following way:

• - rimless eyeglass frames; The glasses are provided with holes and screwed or plugged in the frame parts.
• - nylon eyeglasses; The glasses are provided with a circumferential groove and tightened with a nylon thread.
• - metal eyeglasses; Similar to the nylon goggles, the glasses are provided with a circumferential groove. The eyeglass frame is then usually opened on the strap side of the glasses and closed with different mechanisms after inserting the glass.
• - plastic eyeglasses; the glasses are ground and inserted with the so-called pointed facet (about 120 degrees angle). The eyeglass frame is either heated or the glasses are pressed "cold".
• - metal eyeglasses; The glasses are ground with a pointed facet. The eyeglass frame can be opened in one place and closed again by means of a screw connection. The glasses sit with rel. strong tension.

Technical advantages of the registered utility model

• - the lenses sit with possible. little tension in the glass. This increased security. By the lower Tension minimizes the risk of breakage of the frame.
• - of the Frame leaves open quickly and without tools;
• - by Assembly of different nose plate holders can be an individual better fit of the glasses on the nose can be achieved.

1 shows the glasses diagonally from the front. One recognizes the opening (a) in the spectacle frame.

Of the Eyeglass frame leaves at the opening (a) spread apart. This can be done with a so-called. Spitz facet ground lenses are used in the glasses frame.

Of the Eyeglass frame can be made of plastic, metal or natural horn become.

The glasses are used on the principle of tongue and groove. The frame locking solution can also for circumferentially grooved glasses are applied. Then the groove is a so-called Nylorprofil, which as a counterpart to the glass groove serves, provided.

Of the Plug closure (b) is inserted into corresponding openings (c) of the frame. The precisely cut to the right size Glass is stuck.

The Connection can be done manually without tools at any time, eg. For glass changing, solved become.

2 shows the eyeglass frame in the front view or slightly inclined. You can clearly see the two openings (c) for inserting the tension lock.

Of the Buckle is marked with (b). The two pins (d) fit exactly in the two openings (C).

This leads to a durable, stable and always detachable glass attachment.

The U-shaped opening (s) on the plug closure takes the nose pads on.

Claims (3)

Eyeglass lens attachment with a plug-in closure which holds the eyeglass frame together for firm hold of the lenses, characterized in that two parallel pins (d) of the male fastener are inserted into the two matching recesses (c). Steckverschluss, which simultaneously fixes the nose bridge plates characterized in that the specially for the market Nose bridge plates in the opening (e) be put. Spectacle frame for glass reception characterized, that the frame between the two recesses (c) is severed. Thereby the opening results (A). Of the recesses (c) is one each above and one below the transection of the frame. The resulting Gap (a) in the assembled state allows the glasses with a little more size tolerance incorporate.
