DE7816310U1 - OPTICAL COMPONENT MADE OF TRANSLUCENT GLASS - Google Patents

Description

Evers, Fritz, Mauritz-Lindenweg 33, 4400 Münster "Optical component made of transparent glass"

The innovation relates to an optical component made of transparent, optical glass as a visual aid with two half cubes.

Such optical components are known and are used, for example in order to keep the head of the occupant away from the viewing slit in armored vehicles, so that in the event of a fire and When the eye slit hits the tank occupant's head is protected. Similar optical aids are also used in chemical Industry, especially common in reactor technology and in other technical areas.

For equipment used in the armored vehicle sector

there is a risk that if the optical construction

partly due to the splintering effect of the same, the driver in spite of |

who is hurt. if

The innovation is based on the task of creating an aid with which such a hazard to the occupant of the armored Vehicle is switched off.

This object is achieved in that the component is divided into two parts, the division by an elastic Methacrylate resin layer takes place parallel to the insight beam path and the outlook beam path is aligned and thus when the component that can be hit from the outside is hit prevents the other component from splintering.

According to the innovation, the two can attach to the elastic methacrylate resin layer Adjacent parts consist of colorless silicate glass, according to another feature of the innovation both parts can also be made of acrylic glass.

An exemplary embodiment of the innovation is explained below with reference to the drawing.

In the drawing, 1 generally denotes an optical component, which is used, for example, in an armored vehicle, where E is the viewing beam path and A the outlook beam path is designated. At 2 the eye of the vehicle occupant is shown.

The actual optical component consists of the two parts | 3 and 4, which are \ separated from each other by an elastic separating layer 5, wherein said elastic release layer 5: elastic methacrylate resin is, while the two parts |

3 and 4 made of colorless silicate glass or colorless acrylic glass. J

can be posed. |

It can be seen that, for example, if the component 3 is destroyed, a transmission of the shock waves to the component 4 is not possible, since this transfer is prevented by the elastic layer 5.

This considerably increases the safety of the vehicle occupant.
