FRAMELESS SAFETY EYEGLASSES HAVING CORRECTIVE EYEGLASS LENSES AND LATERAL PROTECTIVE PARTS

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, 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 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.

4. 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.

5. The safety glasses as claimed in claim 1, wherein 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.

6. The safety glasses as claimed in claim 1, wherein at least one guide strip on which the hinge element bears is disposed at least in the side protection part.

7. The safety glasses as claimed in claim 6, 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.

8. The safety glasses as claimed in claim 1, 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.

9. 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.

10. The safety glasses as claimed in claim 1, wherein a hinge element or an articulated connection is a constructive component part of the side protection part.

11. 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.

Description

[0020] An advantageous construction embodiment of the safety glasses according to the invention is explained in more detail hereunder by means of two drawings in which

[0021] FIG. 1 shows the safety glasses 1 according to the invention in a front view, having folded-in arms 5; and

[0022] FIG. 2 shows the safety glasses 1 according to the invention in a perspective lateral view onto the side protection part 3 having folded-out arms 5.

[0023] A design embodiment of the invention that is composed of two corrective lenses 2 as eyeglass lenses, which are interconnected by a centrically disposed nose bridge 7, is illustrated in a front view in FIG. 1. Fastening of the nose bridge 7 herein is performed directly into the plastics material lenses of the corrective lenses 2.

[0024] The connection between the corrective lenses 2 and the side protection part 3 herein is illustrated as a dashed line. The connection region between the corrective lens 2 and the side protection part 3 herein follows the external contour of the corrective lens 2. In this way, the side protection part 3 and the eyeglass 2 may bear in a planar manner on one another in an overlap region 4, this substantially improving the stability of the connection between the corrective lens 2 and the side protection part 3.

[0025] However, alternative construction embodiments in which the corrective lens 2 and the side protection part 3 are interconnected, for example adhesively bonded, in a squarely abutting manner, are also provided. A groove-type connection may be performed herein in the connection region. Moreover, the connecting function of the hinge part 6 herein may act in a stabilizing manner, to the extent that said hinge part 6 is connected to the eyeglass 2 and to the side protection part 3, for example.

[0026] In the present construction embodiment, a screw connection of these two components is established by a fastening screw 8 which in the overlap region 4 runs between the corrective lens 2 and the protection part 3. In the present construction embodiment, this screw connection is additionally performed into the hinge part 6 that supports the arm 5.

[0027] This is highlighted in particular again in FIG. 2. A hinge body 6, having an approximate l-shape, runs from the overlap region 4 of the corrective lens 2 and the protection part 3, so as to follow the contour of the protection part 3, up to approximately the central region of the side protection part 3. In the present construction embodiment, the hinge body 6 is connected in a frontal manner by way of the fastening screw 8 to the components being the corrective lens 2 and the protection part 3, on the one hand. Moreover, an additional adhesive connection or welded connection to these components is expedient.

[0028] Moreover, in the present construction embodiment, guide strips 9 are disposed internally on the side protection part 3 so as to be above and below the side protection part 3 in such a manner that these guide strips 9 serve for aligning and disposing the hinge body 6. On account thereof, positioning of the hinge body 6 on the side protection part 3, on the one hand, as well as the stability of the fastening of the hinge body 6 is facilitated. At the end thereof, the hinge body 6 has the articulated connection 10 to the arm 5.

[0029] On account thereof, advantageous safety glasses 1 are produced which are configured as an integral body without a spectacle frame, wherein the elementary construction elements of the eyeglass lenses 2, of the side protection parts 3, as well as of the arms 5 are fixedly interconnected.
