Abstract

The invention relates to safety eyeglasses, in particular working safety eyeglasses or sports safety eyeglasses, having corrective eyeglass lenses for compensating defective vision, the safety eyeglasses comprising lateral protective parts (3) and eyeglass temples (5), wherein the safety eyeglasses (1) are designed as frameless eyeglasses and the corrective lenses (2) are designed as plastic lenses, which are rigidly connected to lateral protective parts (3) to be attached temporally, wherein the lateral protective parts (3) are integrally formed on the corrective lenses in an accurately fitting manner in the connection region to the corrective lenses (2) such that the curve course of the corrective lenses is reproduced by the lateral protective parts (3) in the connection region.

Claims

1. Safety glasses with corrective safety-eyeglass lenses for correcting ametropia, comprising side protection parts and arms,

wherein

the safety glasses are configured as frameless glasses,

wherein the corrective lenses are configured as plastics material lenses which are fixedly connected to side protection parts that attach in a temporal manner, and the corrective lenses in an overlap region bear in a planar manner on the side protection parts that are molded in an exact fit, and in this connection region are adhesively bonded and/or welded and/or screwed to the side protection parts,

wherein the side protection parts in the connection region to the corrective lenses are molded to the latter in an exact fit such that the curved profile of the corrective lenses is mirrored by the side protection parts in the connection region.

2. The safety glasses as claimed in claim 1,

wherein

the corrective lenses in the nasal region are connected by a nose bridge which is adhesively bonded and/or welded and/or screwed so as to be fixed to the plastics material lenses.

3. The safety glasses as claimed in claim 1,

wherein

the corrective lens and the side protection part in the temporal connection region are configured so as to squarely abut one another, and in this region are adhesively bonded and/or welded to one another.

4. The safety glasses as claimed in claim 1,

wherein

the side protection part and/or the corrective lens in the overlap region have/has a graduation which effects a connection by way of an exact fit of these components in this connection region.

5. The safety glasses as claimed in claim 1,

wherein

the side protection part and the corrective lenses in the lateral connection regions thereof are configured in such a manner that the side protection part in only one construction embodiment is laterally attachable to the two corrective lenses, and thus both side protection parts are identically configured.

6. Safety glasses with corrective safety-eyeglass lenses for correcting ametropia, comprising side protection parts and arms,

wherein

the safety glasses are configured as frameless glasses,

the corrective lenses are configured as plastics material lenses which are fixedly connected to side protection parts that attach in a temporal manner,

the side protection parts in the connection region to the corrective lenses are molded to the latter in an exact fit such that the curved profile of the corrective lenses is mirrored by the side protection parts in the connection region, and

a hinge element is disposed internally or externally on the side protection part, and is welded and/or adhesively bonded and/or screwed to the latter.

7. The safety glasses as claimed in claim 6,

wherein

at least one guide strip on which the hinge element bears is disposed at least in the side protection part.

8. The safety glasses as claimed in claim 7,

wherein

the hinge element is guided between two guide strips so as to be disposed internally on the side protection part, and is adhesively bonded and/or welded and/or screwed to the latter.

9. The safety glasses as claimed in claim 6,

wherein

at least one bore runs in the connection region of the corrective lens and the side protection part, by way of which bore the components of the corrective lens, of the side protection part, and of the hinge element are interconnected by one fastening screw.

10. The safety glasses as claimed in claim 6,

wherein

the corrective lenses in an overlap region bear in a planar manner on the side protection parts that are molded in an exact fit.

11. The safety glasses as claimed in claim 6,

wherein

the side protection part and the corrective lenses in the lateral connection regions thereof are configured in such a manner that the side protection part in only one construction embodiment is laterally attachable to the two corrective lenses, and thus both side protection parts are identically configured.

12. Safety glasses with corrective safety-eyeglass lenses for correcting ametropia, comprising side protection parts and arms,

wherein

the safety glasses are configured as frameless glasses,

the corrective lenses are configured as plastics material lenses which are fixedly connected to side protection parts that attach in a temporal manner,

the side protection parts in the connection region to the corrective lenses are molded to the latter in an exact fit such that the curved profile of the corrective lenses is mirrored by the side protection parts in the connection region, and

a hinge element or an articulated connection is a constructive component part of the side protection part.

13. The safety glasses as claimed in claim 12,

wherein

the corrective lenses in an overlap region bear in a planar manner on the side protection parts that are molded in an exact fit.

14. The safety glasses as claimed in claim 12,

wherein

the side protection part and the corrective lenses in the lateral connection regions thereof are configured in such a manner that the side protection part in only one construction embodiment is laterally attachable to the two corrective lenses, and thus both side protection parts are identically configured.
