Abstract

Spectacle front with frame open to the nose side with separate clamping clasp which closes the spectacle frame.
characterized,
that above and below the frame opening rasters are present in which engage the openings of the clamping clip.
In the opposite case, the openings can also be in the spectacle front and the grids in the clamping clasp.
The clip is also a holder for the nose pads. Since various commercially available platelet shapes are available on the market, the protection claim is claimed for these variants.
The shape of the clamping clip changes accordingly.

Description

Current technical status:

Eyeglass frames:

gland:

at most of the frames built to date with frames, d. H. a spectacle front which serves the glass receptacle, the lenses are in the open Used frame and this is then using a so-called. Locking block closed. The locking block consists of two parts, through which runs a thread. A Screw connects the two parts.

Thermal insertion of the glasses:

A Another common way of fixing glass is through the thermoplastic Properties of the spectacle frame achieved. The front of the glasses is heated, the Material expands easily. The ground to appropriate size glasses are pressed in and the frame shrinks when cooled together again. The glasses are fixed.

Nylorverglasung:

at this variant, the glasses frame is usually open at the bottom and the glasses are clamped using an elastic nylon thread. The glasses will be here with a circumferential groove provided in which the thread slips and thus ensures the seat of the glass.

Open sheet metal frame:

The The most modern version of the frames are made of sheet metal. These frames are usually at the temporal location (towards the temple) severed. By opening the frame becomes the glasses used. The glasses have as in the Nylorverglasung a circumferential groove. Of the stable shuttering of the frame is usually done via appropriately designed Temples, which is connected to the front of the glasses by means of plug connections become.

Most of time will be additional small brackets are needed to lock the frame.

Description:

at the variant described here is the sheet metal frame at the Open nose side.

Of the Frame is closed with an elastic clip.

These Clamp is made using two openings attached to corresponding grids of the frame.

Technical advantages of the registered utility model

• - Of the Eyeglass frame leaves open very easily and shut down.
• - The Glazing with the lenses takes very little tension - thereby reduced risk of breakage
• - By the screw and weld-free connections is the glasses very low in wear
• - The Clamp clip serves at the same time the inclusion of the so-called nose pad. This inserted element serves the comfortable support on the nose of the spectacle wearer

Claims (1)

Spectacle front with frame open to the nose side with separate clamping clasp which closes the spectacle frame. characterized in that above and below the frame opening rasters are present in which engage the openings of the clamping clasp. In the opposite case, the openings can also be in the spectacle front and the grids in the clamping clasp. The clip is also a holder for the nose pads. Since various freely available platelet shapes are available on the market, the protection claim is claimed for these variants. The shape of the clamping clip changes accordingly.
