They are preferably designed to be complementary to each other in at least one interaction area. The at least one lower pre-centering pivoting means is preferably arranged in a lateral edge or end region of the lens assembly. It is advantageous if a pair of lower pre-centering pivoting means and a pair of lower pre-centering pivoting counter-measures are present.

[0015] The at least one upper pre-centering means and the at least one upper pre-centering counter-measure ensure a robust and easily achievable connection between the lens assembly and the spectacle frame. They are, for example, designed to be complementary to each other in at least one interaction area. The at least one upper pre-centering means is preferably arranged in a lateral edge or end region of the lens assembly. It is advantageous if one pair of upper pre-centering means and one pair of upper pre-centering counter-measures are present.

[0016] The spectacles are particularly stable and durable when assembled, comprising the lens assembly and the frame. It is advantageous for the lens assembly and the frame to be directly connected when assembled. The frame surrounds the lens assembly, particularly in certain areas, from above. A tongue-and-groove joint exists between the lens assembly and the frame, at least in some areas.

[0017] The lens assembly comprises, for example, exactly one single, continuous lens. Alternatively, it may have, for example, two lenses. The lens assembly is preferably interchangeable.

[0018] The spectacle frame is preferably able to hold or support the lens assembly when the lens assembly and the frame are assembled.

It is advantageous if the lens assembly receptacle is open at the bottom. The spectacle frame is preferably made of plastic. It is preferably an injection-molded part.

[0019] It is advantageous for the eyeglasses to have a head-holding device for securing the lenses to the wearer. The head-holding device is preferably located on the eyeglass frame. It is formed, for example, by at least one retaining strap that wraps around the back of the wearer's head when the eyeglasses are worn. Alternatively, it is formed, for example, by two temples, which are particularly pivotable.

[0020] Preferably, the lens assembly and the frame are separable. It is advantageous if the separation or disassembly of the lens assembly and the frame is carried out (essentially) analogously to the assembly of the lens assembly and the frame, preferably without tools.

[0021] It is advantageous if the glasses are symmetrical with respect to a principal plane.

[0022] A nose support device, designed to brace the spectacle frame against the wearer's nose, results in exceptionally high wearing comfort. It is advantageous if it is at least partially flexible. The nose support device is preferably an integral part of the spectacle frame.

[0023] The nasal support device receptacle and the nasal support device are preferably designed to be complementary to each other. The nasal support device is preferably (essentially) V- or Y-shaped.

[0024] Further advantageous embodiments of the invention are specified in the dependent claims.

[0025] The embodiment according to dependent claim 2 allows for a controlled or defined pivoting of the lens assembly and the frame for assembly. This assembly process is therefore particularly reliable, easily controllable, and user-friendly.

[0026] The at least one lower pre-centering swivel means is designed as a receptacle, in particular a keyhole-shaped receptacle, in particular a keyhole-shaped detent receptacle, according to dependent claim 3. The receptacle is preferably open downwards. It is advantageously limited upwards and laterally.

[0028] The at least one lower pre-centering pivot and the at least one lower pre-centering pivot counter-measure preferably form a first pre-centering pivot and pre-centering pivot counter-measure, respectively. It is advantageous if the lower pre-centering pivot counter-measure and the at least one lower pre-centering pivot are in a snap-fit ​​connection, particularly detachable, with each other during assembly of the lens assembly and the frame, and in their assembled state. This is particularly easy to assemble and results in a highly reliable pair of glasses. It is advantageous if the at least one lower pre-centering pivot is an integral part of the lens assembly. Even more advantageously, the at least one lower pre-centering pivot is an integral part of the frame.

[0029] According to subclaim 4, the at least one upper pre-centering means is designed, for example, as a web, in particular a contact web, plate, pin or the like.

[0030] The at least one upper pre-centering countermeasure is preferably designed as a receptacle, contact surface, contact flank or the like.

[0034] The embodiment according to dependent claim 6 also results in spectacles that are particularly stable and / or resilient in the assembled state of the lens assembly and the frame. Preferably, a positive-locking connection exists between the nose support device and the nose support device receptacle. For example, the nose support device rests against or is supported on the lens assembly or the nose support device receptacle at the bottom, top, and / or side.

[0035] The design according to dependent claim 7 also results in spectacles that are particularly stable and / or durable. It is advantageous if the nose support device, especially independently, pivots or springs back to its initial position after being pivoted from its starting position or wearing position into a mounting position.

[0036] The nose support device according to subclaim 8 is, for example, pivotable forwards and upwards.

[0037] The frame component according to dependent claim 9 is at least partially torsionally capable or rotatable within itself, preferably about its longitudinal central axis. It is preferably elastic at least partially in that area.

[0038] The terms "above", "below", "front", "back", "rear", "side" or the like used here refer in particular to the orientation of the glasses when worn properly by a wearer of glasses.

[0039] A preferred embodiment of the invention is described below by way of example with reference to the accompanying drawing. The drawing shows: Fig. 1 a perspective view of spectacles according to the invention in their fully assembled state or wearing position, Fig. 2 a section through the in Fig. 1 illustrated glasses that pass through their nose area, Fig. 3 a section through the in Fig. 1 The glasses shown are offset laterally to the cut according to Fig. 2 Fig. 4 is an exploded view of the Fig. 1 The glasses shown, Fig. 5, are a rear view of the spectacle frame of the glasses shown in Fig. 5. Fig. 1 The glasses shown, and Figs. 6 to 8 are views illustrating the assembly of the spectacle frame and lens arrangement.

[0040] One in Fig. 1 The spectacles, illustrated in their entirety and fully assembled state, comprise a spectacle frame 1, a lens assembly 2 held by the spectacle frame 1, and two temples 3 hinged to the ends of the spectacle frame 1. The spectacles are symmetrical with respect to a plane of symmetry S that passes through the nose area.

[0041] The lens assembly 2 is a single piece and symmetrically designed. It comprises two lenses 4 arranged side by side and a connecting bridge 5 that runs between the lenses 4 and connects them to each other in an arc at the top. The lens assembly 2 is curved.

[0042] The lens assembly 2 also has two connecting arms 6 that are attached to the bottom of the connecting bridge 5. The connecting arms 6 are spaced apart from each other and extend downwards from the connecting bridge 5. They extend away from each other from the connecting bridge 5. Each connecting arm 6 extends adjacent to a lens 4.

[0043] Each connecting arm 6 has at its bottom a retaining projection or retaining extension or retaining shoulder 7 projecting towards the plane of symmetry S, which forms a retaining surface 8 facing upwards or towards the connecting web 5.

[0044] The connecting bridge 5, the connecting arms 6 and the retaining elements 7 form or limit a nose support device receptacle.

[0045] The connecting web 5 carries a locking element 9 at its upper front, which projects forward and is elongated. It extends perpendicular to the plane of symmetry S and is, for example, cuboid-shaped or web-shaped.

[0046] The lens assembly 2 further comprises two end elements 10 at the top. Each end element 10 is, for example, designed like a bridge and adjoins a lens 4 at the top. Each end element 10 extends laterally outwards from the connecting bridge 5.

[0047] Furthermore, the spectacle lens arrangement 2 has two side elements 11 which connect laterally to the respective end element 10 and the respective spectacle lens 4.

[0048] Each side element 11 has a keyhole-shaped recess 12 at its bottom, which is continuous and open at the bottom. Each recess 12 is bounded by two opposing insertion flanks 13 that converge from bottom to top. Each recess 12 also has an inner pivot bearing area 14, which adjoins the two insertion flanks 13 and has a semicircular or circular cross-section. Each pivot bearing area 14 has a maximum transverse extent that is (slightly) greater than the adjacent (minimum) distance between the insertion flanks 13. Each recess 12 forms a first or lower pre-centering pivot recess.

[0049] Each side element 11 also has a pre-centering means 15, which is arranged above the adjacent receptacle 12. Each pre-centering means 15 is arranged at the edge of the respective side element 11 and projects backwards. Each pre-centering means 15 forms a second or upper pre-centering means. Each pre-centering means 15 is designed as a projection and is, for example, rib-like, plate-like, pin-like, or the like.

[0050] The eyeglass frame 1 is a single piece and symmetrical. It extends in a curved shape.

[0051] The spectacle frame 1 comprises an upper elongated frame part 16 and a nose support device 17 projecting downwards from the center of the upper frame part 16. Furthermore, the spectacle frame 1 has two lateral end elements 18 that connect laterally to the respective frame part 16 on the outside.

[0052] The frame part 16 is designed to be elastic or flexible, at least in some areas. In particular, when an external force is applied about its longitudinal central axis, it can be torsionally twisted in a circumferential direction U, so that the nose support device 17 can move upwards from its supporting position relative to the end elements 18 ( Fig. 1 ) is pivotable. The frame part 16, for example, has a square and / or round cross-section.

[0053] The nose support device 17 comprises two adjacent nose support struts 19 and a connecting body 20 between them. The nose support struts 19 are elongated and extend downwards from the connecting body 20. They diverge from the connecting body 20 towards each other. Each nose support strut 19 has an internal nose support surface 21, which rests on the nose of a wearer of the glasses (not shown) when the glasses are worn.

[0054] Each end element 18 carries an upper pivot attachment 22 with an upper cylindrical bearing recess 23 and a lower pivot attachment 24 with a lower cylindrical bearing recess 25. The bearing recesses 23, 25 of each pivot attachment 22, 24 are arranged one above the other and define a pivot axis for the respective temple 3.

[0055] Each end element 18 also carries a pre-centering pin 27 ( Fig. 5 ), which is semicircular or circular in cross-section. Each pre-centering pin 27 is arranged above the adjacent lower pivot point 24. For example, each pre-centering pin 27 directly adjoins the adjacent lower pivot point 24 at the top. The pre-centering pins 27 are arranged on the inside of the end elements 18. They form lower or first pre-centering pins 27.

[0056] Each end element 18 also has a pre-centering contact element 30, which is formed above the adjacent pre-centering pin 27. Each pre-centering contact element 30 is located on the inside of the respective end element 18 and is arranged, for example, at the end or spaced apart from an outer end of the respective end element 18. The pre-centering contact elements 30 are formed by an inner surface or inner flank of the respective end element 18. They are, for example, open or limited downwards, upwards, inwards, and / or outwards. They form upper or second pre-centering contact elements 30.

[0057] The eyeglass frame 1 also has an elongated ratchet recess 26 on the back center ( Fig. 5 ), which is designed to be complementary to the grid body 9.

[0058] Each temple 3 has an upper bearing body 28 and a lower bearing body 29. The bearing bodies 28 and 29 are each pin-shaped or cone-shaped, respectively. They are arranged one above the other on each temple 3 and, for example, spring away from each other. The upper bearing bodies 28 are complementary to the upper bearing recesses 23, while the lower bearing bodies 29 are complementary to the lower bearing recesses 25. Alternatively, a different arrangement of the bearing bodies 28 and 29 and the bearing recesses 23 and 25 is possible. For example, each temple 3 has exactly one bearing body 28 or 29.

[0059] The following also refers to Fig. 6 bis 8 The assembly of the spectacle frame 1 and the spectacle lens arrangement 2 as well as the spectacle temples 3, that is, their mounting, is described.

[0060] The spectacle frame 1, the spectacle lens arrangement 2 and the spectacle temples 3 are originally separate.

[0061] First, the pre-centering pins 27 are guided, preferably simultaneously or uniformly, from below through corresponding insertion openings in the receptacles 12 and the insertion flanks 13 into the pivot bearing areas 14. Alternatively or additionally, the receptacles 12 are moved relative to the pre-centering pins 27 accordingly.

[0062] The pre-centering pins 27 temporarily push the insertion flanks 13 apart and engage or snap into the respective pivot bearing area 14. Alternatively or additionally, the pre-centering pins 27 can be compressed to enter the respective pivot bearing area 14. Each pivot bearing area 14 provides a partial pivot axis and forms a pivot bearing for the respective pre-centering pin 27. The partial pivot axes essentially coincide and provide a common pivot axis.

[0063] Subsequently, the spectacle frame 1 and the lens assembly 2 are pivoted relative to each other in a controlled manner about the common horizontal lower pivot axis defined by the pivot bearing areas 14, over a correspondingly defined pivot path, so that the connecting bridge 5 and the nose support device 17 approach each other. During this approach, the lens assembly 2 is located in front of the nose support device 17. Alternatively, a different design or configuration of the lens assembly 2 and / or nose support device 17 is possible.

[0064] The nose support device 17 is then manually pivoted forward and upward, which is possible due to the torsionally flexible frame part 16. The lens assembly 2 is thus able to pivot past the nose support device 17.

[0065] After passing the nose support device 17, the nose support device 17 pivots back down into its carrying position. This can be done manually. However, the nose support device 17 can also pivot back into its carrying position automatically due to its spring-back capability.

[0066] The pre-centering means 15 are guided along the inside of the end elements 18 and reach the pre-centering support means 30, where they lie, in particular over a surface.

[0067] The locking element 9 engages in the locking recess 26.

[0068] The nasal support device 17 engages in the nasal support device receptacle ( Fig. 1 , 5 ).

[0069] The end elements 10 engage with the frame part 16 from below ( Fig. 3 ).

[0070] Subsequently, the upper bearing body 28 of each temple 3 is inserted from below into the upper bearing recess 23 and the lower bearing body 29 is inserted from above into the lower bearing recess 25, so that the temple 3 is hinged to the frame 1 accordingly.

[0071] In the fully assembled state, the nose support struts 19 connect to the inner sides of the connecting arms 6 and preferably also to the lower connecting strut 5. Each nose support strut 19 is supported at its base against the retention surface 8 of the respective retention attachment 7.

[0072] The lens assembly 2 is fixed upwards, downwards, and laterally, and preferably forwards, relative to the spectacle frame 1 by the engagement of the locking element 9 in the locking recess 26. The lens assembly 2 is fixed forwards, backwards, upwards, and, for example, also laterally relative to the spectacle frame 1 by the engagement of the support elements 10 from below into the frame part 16. The lens assembly 2 is fixed laterally, downwards, and preferably upwards relative to the spectacle frame 1 by the engagement of the nose support device 17 in the nose support device receptacle. The lens assembly 2 is fixed laterally relative to the spectacle frame 1 by the contact of the pre-centering means 15 on the inside of the end elements 18. The spectacle frame 1 and the lens assembly 2 are clamped together in the assembled state. They are detachably connected to each other.

[0073] When wearing the glasses, the nose pads 21 lie flat against the wearer's nose. The nose bridges 19 ensure comfortable wear and a secure fit. The lenses 4 are positioned in front of the wearer's eyes. The temples 3 rest against the sides of the wearer's head.

[0074] Disassembly is essentially carried out in the same way. This also involves a controlled pivoting of the spectacle frame 1 and the spectacle lens assembly 2 relative to each other.
