The present patent application claims the priority of German Patent Application DE 10 2016 218 941.7, the content of which is incorporated herein by reference.

The invention relates to a spectacle arrangement.

It often happens that light conditions, sometimes very fast, change. This can be dangerous for people who have to cope with such lighting conditions. The prior art discloses glasses whose tint is changeable.

In US 2014/0259252 Al an arrangement of an automatically darkened glasses and a mask part is disclosed. The mask part is attachable to the outside of the glasses. There are hooks available. The glasses have an LCD screen to block harmful light. Further, the goggle has a light detection sensor and a power supply to power the LCD panel, if necessary. The spectacles can be fixed to the head of a wearer by means of a fixing band. The fixation of the mask part is not satisfactory.

The invention has for its object to provide a goggle assembly that is very user-friendly.

This object is achieved by the features specified in the claim 1. The essence of the invention lies in the fact that, in the coupled or assembled state of the spectacle arrangement, the insert causing the tinting and the wearer of the spectacles through the protective spectacles, is protected in particular from external mechanical influences, such as shock, impact or the like. In general, the use is much more expensive than the safety goggles, which is preferably designed as working safety goggles. The insert is conveniently kept on the goggles.

The goggles, for example, interchangeable, if this is about damaged. The possibly much more expensive use, however, can continue to be used. Alternatively, however, the use is interchangeable, for example, if he has a defect. It is thus avoidable that the entire spectacle assembly must be replaced if one of their main components, ie use or safety glasses, is defective.

The at least one coupling part is conveniently arranged for reasons of strength on the insert frame. It is expedient if the at least one coupling part is arranged at the top of the insert. Conveniently, there are two such coupling parts which are preferably adjacent but spaced from one another.

The design of the at least one coupling part as Umgreifklam- mer allowed on the one hand a very stable connection of the insert to the goggles. On the other hand, a solution of the use of the safety goggles which can be brought about simply is also possible.

The at least one additional coupling part is conveniently arranged on the insert frame for reasons of strength. It is expedient if the at least one additional coupling part is arranged on top of the insert. It is preferably designed as a projection. In the assembled state of the spectacle assembly, the use is due to the Record set especially well in and against the line of sight fixed to the goggles.

For reasons of strength, the at least one further coupling part is conveniently arranged on a, for example closed, goggle frame or protective goggle frame element of the protective goggles. The at least one further coupling part is preferably arranged on top of the protective goggles. The tint of the at least one tintable tinting pane adapts itself automatically or automatically to the prevailing lighting conditions of the environment, which is particularly user-friendly. There is then preferably an automatic darkening or lightening of the at least one tinting disc. Conveniently, the at least one tinting disc, which is self-tinting, is embodied as an LC (liquid crystal) tinting disc or PDLC (polymer dispersed liquid crystal) tinting disc or electrochromic or electrochromatic tinting disc. Alternatively or additionally, the tinting of the at least one tinting disc by the wearer himself by a Tö- nungs adjustment element, for example by pressing a button, switch or the like, changeable.

In the tinted state of the at least one tinting disc, the eyes of the spectacle wearer are particularly well protected against harmful or unpleasant radiation, which arises, for example, when using appropriate working methods, such as welding. In addition, the wearer is then safely protected from glare, for example, by the sun. In untinted condition of at least one tinting disc is a substantially ensures an unadulterated view of the spectacle wearer. It is advantageous if the tint of the at least one tinting disc is reversible.

The at least one protective screen is favorably designed as a single, continuous disc. Alternatively, there are two separate shields. The at least one protective screen is conveniently untuned. Alternatively, the at least one protective pane at least in areas, for example, a contrast-enhancing tint, such as in the color amber, and / or a tint to protect against, in particular artificial, radiation, such as laser radiation with a certain wavelength. The at least one protective pane is preferably impact-resistant and / or bullet-proof.

The coupling device preferably allows a positive and / or non-positive connection between the insert and the

Safety goggles. In particular, the coupling device between the insert and the safety glasses allows a magnetic connection, a latching connection, a plug connection, a latch connection and / or a clamping connection.

The insert is conveniently designed as a separate part. It is useful if the use can be retrofitted with conventional goggles. The insert is preferably without its own head holding means, in particular ironless executed. It is expedient if the insert has a nose recess.

The at least one head-holding means of the protective goggles is, for example, as eyeglass temple, headband for circulating an occiput of the spectacle wearer. gers or the like. It is directly or indirectly connected to the at least one protective screen.

Conveniently, the goggles have a nose cup.

The eyeglass assembly is conveniently designed to be substantially symmetrical with respect to a plane of symmetry.

Further advantageous embodiments of the invention are specified in the subclaims.

The insert frame according to the dependent claim 2 protects the at least one tinting disc. Furthermore, such an insert conveniently has a particularly high rigidity. The insert frame is preferably closed on the circumferential side. The at least one tinting disc is then preferably inserted into the insert frame. The insert frame can also be made open. Alternatively, the use is frameless.

The at least one electrical energy source according to the dependent claim 3 is designed, for example, as a current source and / or voltage source, in particular a DC voltage source. Conveniently, the at least one electrical energy source is rechargeable and / or replaceable. In particular, it supplies the at least one tinting disc with electrical energy, if necessary.

It is advantageous if the prevailing tint of the at least one tinting disc is maintained if there is no supply of electrical energy to the at least one tinting disc. The tint of the at least one tint disc is preferably maintained until it is again supplied with electrical energy.

The tinting control unit according to the dependent claim 4 is preferably designed as a control unit and / or control unit. Advantageously, an adjustment of the tinting of the at least one tinting disc by the tinting control unit to changing light conditions within 2 seconds, more preferably within 1 second, more preferably within 0.1 seconds.

Conveniently, the at least one brightness sensor or

Light sensor according to the dependent claim 5 a transmitter. It is advantageous if the at least one brightness sensor has at least one photodiode. It is expedient if the at least one brightness sensor is arranged on the front side on the insert or on a side of the insert facing away from the wearer of the spectacles. Alternatively or additionally, as already mentioned, a manual adjustment of the tint of the at least one tinting disc is possible. It is advantageous if the insert, conveniently on the back, comprises a charging connection for electrically charging the at least one energy source and / or an on / off switch for switching on or off the at least one energy source. The embodiment according to the dependent claim 6 leads to a particularly effective protection of the insert from external mechanical influences. In particular, the protective cover completely covers the insert, which is in the mounted and worn state, in particular between the face of the wearer and the protective glass. According to the dependent claim 7, the at least one protective pane in the assembled state of the spectacle arrangement extends at least largely over the insert. It is advantageous if the at least one protective pane then extends at least completely over the at least one tinting pane, in particular at least over its entire width and / or height. The at least one protective pane preferably completely covers the at least one tinting pane. The at least one tinting disc is thus arranged between the spectacle wearer and the at least one protective pane when the spectacle arrangement is intended to be carried by the spectacle wearer.

The embodiment according to the dependent claim 8 allows a simple to bring about solution of the use of goggles and vice versa, a very stable connection of the insert to the goggles.

In the assembled state of the spectacle arrangement, the at least one further coupling part between the two coupling parts expediently engages in the manner of a tie, provided that two of these coupling parts are present.

Conveniently, the at least one coupling part and the at least one further coupling part as well as the at least one additional coupling part together ensure a functionally reliable mechanical coupling between the insert and the protective goggles.

Hereinafter, a preferred embodiment of the invention will be described by way of example with reference to the accompanying drawings. Showing: 1 is a rear view of an assembled spectacle assembly according to the invention in its entirety,

Fig. 2 is an exploded view of the insert of the spectacle assembly shown in Fig. 1 from the front, and

FIG. 3 is a front view illustrating part of the eyeglass assembly illustrated in FIG. 1. FIG.

An eyeglass assembly shown in the figures has an insert 1 and a pair of protective goggles 2 as well as a coupling device 3 which is capable of releasably coupling the insert 1 and the protective goggles 2 together. In the assembled state of the spectacle arrangement, the protective spectacles 2 are arranged downstream of the insert 1 in a viewing direction 4 of the spectacle arrangement.

The insert 1 has a closed insert frame 5 and two tintable tinting discs 6, which are inserted in corresponding, juxtaposed openings 7 of the insert frame 5 in a form-fitting manner.

Between the openings 7 and the tinting disks 6, the insert 1 has a nose recess 8. The insert frame 5 has adjacent to the nose recess 8 two opposing Nasenabstützteile 9 for support against a nose of a spectacle wearer (not shown). It is advantageous if the Nasenabstützteile 9 are resilient or elastic. Above the nose recess 8 are located in the insert frame 5, an electric power source 10 and a tinting control unit 1 1 and a brightness sensor 12 for detecting a brightness of an environment.

The energy source 10 is connected via a first supply line 13 with the tinting control unit 1 1 in electrical connection. It is also connected via a second supply line 14 with the brightness sensor 12 in electrical connection. The tinting control unit 1 1 in turn is connected via a signal line 15 with the brightness sensor 12 in signal connection.

The power source 10 supplies via the first supply line 13, the tinting control unit 1 1 with electrical energy. Via the second supply line 14, the electrical energy source 10 supplies the brightness sensor 12 with electrical energy. The tinting control unit 11 receives via the signal line 15 from the brightness sensor 12 corresponding brightness values or signals of the environment. This is done in particular only when the power source 10 is turned on and has sufficient energy.

Via a running between the tinting control unit 1 1 and the power source 10 control line 30, the electric power source 10, depending on the respectively detected brightness value of the Tönungs-control unit 30, if necessary, operated to the tinting discs 6 with a for a setting of for to supply the tint needed electrical energy. For this, the electrical energy source 10 is connected via a third supply line 16 with the tinting disks 6 in electrical connection. Alternatively, there is another electrical circuit. The power source 10, the tinting control unit 1 1, the brightness sensor 12 and the charging terminal, if any, and the on / off switch, if any, are integrated into one unit. They are housed in a common block-shaped housing 17 which is inserted above the nose recess 8 in a corresponding recess 18 in the insert frame 5.

Above the nose recess 8 and the recess 18, two first coupling parts 19, which are part of the coupling device 3, are arranged on the front of the insert frame 5 in the viewing direction 4. The first coupling parts 19 are spaced next to each other, that is perpendicular to the viewing direction 4, arranged. Each first coupling part 19 is designed as an encompassing clip, which is open opposite to the viewing direction 4 and has a corresponding assembly / disassembly opening 20 there.

Further, the coupling device 3 has a second coupling part 21, which is arranged between the first coupling parts 19 and projects there from the insert frame 5 upwards. The second coupling part 21 is arranged at the rear on the insert frame 5. The first coupling parts 19 and the second coupling part 21 are arranged so as to be spaced apart in the viewing direction 4.

The insert 1 has perpendicular to the viewing direction 4, a maximum outer width BE. Furthermore, the insert frame 5 has a maximum height HE perpendicular to the width BE and the viewing direction 4.

The protective goggles 2 has a single, continuous protective disk 22. The protective disk 22 has a nose receptacle 23. Conveniently, the Protective disk 22 adjacent to the nose receptacle 23 made soft or yielding.

The protective pane 22 has a maximum outer width BS perpendicular to the viewing direction 4. Perpendicular to the viewing direction 4 and the width BS, the protective plate 22 has a maximum height HS. The height HS is greater than the height HE. The width BS is greater than the width BE.

According to the present exemplary embodiment, the protective pane 22 favorably has in each side end region 24 a side protection field projecting counter to the viewing direction 4. Alternatively, such offset side protection fields are not present. It is advantageous if the protective pane is then shaped such that it has a seamless or integrated side protection. For this purpose, the protective pane preferably extends (arcuately) around the face of the spectacles wearer and ends laterally with respect to the eyes of the spectacle wearer, so that the

Protective screen offers a side protection.

Above the protective pane 22, the protective goggles 2 have a web-like frame element 26.

From the frame member 26 projects centrally an engagement projection 27 forward and downward. The engagement projection 27 is disposed on the front of the frame member 26. He has perpendicular to the viewing direction 4 has a width BV, which corresponds approximately to the distance of the first coupling parts 19 to each other.

The protective goggles 2 also comprise two temple pieces 28, which are articulated in side regions 29 to the frame element 26. When the spectacle assembly is intended to be worn in its assembled state, a nose of the spectacle wearer engages in the nose recess 8 of the insert 1 and in the nose recess 23 of the protective spectacles 2. The eyeglass arrangement is supported by the nose support parts 9 and possibly also by a region of the protective eyewear 2 adjacent to the nose receptacle 23 with respect to the nose of the wearer of the eyeglass.

About the eyeglass temple 28, the eyeglass assembly is securely held on the head of the wearer.

The tinting discs 6 and the protective plate 22 are then in front of the eyes of the wearer. The tinting discs 6 have a smaller distance to the eyes of the wearer than the protective shield 22nd

When the brightness sensor 12 detects a change in the brightness of the surroundings, the tinting control unit 11 receives a corresponding luminance signal representative of the currently prevailing brightness of the environment. The tinting control unit 1 1 then causes, if necessary, the electric power source 10 to supply the tinting disks 6 with electric power (voltage / current) in order to adjust the tint of the tinting disks 6, that is, dimming or brightening.

The engagement projection 27 engages in the assembled state of the spectacle assembly from above positively between the first coupling parts 19, which prevents displacement of the insert 1 along the frame member 26. The first coupling parts 19 surround the front of the Frame member 26, while the second coupling member 21 engages behind the frame member 26. The insert 1 is held securely on the goggles 2.

To couple the insert 1 and the protective goggles 2 via the coupling device 3, a relative pivoting movement or tilting movement between them is favorably carried out.

As already mentioned, the insert 1 and the protective goggles 2 are separable from each other. This is done by a relative pivoting or tilting movement of the insert 1 and the goggles 2 against each other.
