Abstract

The invention relates to spectacles (1) comprising a frame (2) extending along a longitudinal direction (FLR) and two temples (3) extending along a longitudinal direction (BLR). Each of the two temples (3) is pivotable relative to the frame (2) by means of two hinges (4a, 4b). The spectacles thus have a total of four hinges. According to the invention, at least one temple (3, 3l, 3r) can be locked in an over-tensioned position by means of its two associated hinges (4a, 4b), in which the temple (3, 3l, 3r) projects laterally outwards from the spectacles (1) or from the frame (2).

Description

[0001] The present invention relates to spectacles. Modern spectacles are typically equipped with a frame into which at least one lens can be inserted. Conventional spectacles have temples that can be adjusted relative to the frame between a wearing position and a stowed position. In the wearing position, the temples generally protrude substantially perpendicularly from the frame; in the stowed position, they are folded inward, toward the frame, relative to the wearing position.

[0002] A common problem with conventional glasses is that when folding the temples from the storage position to the wearing position, they can accidentally be moved beyond the wearing position and overstretched. This can result in damage, or in extreme cases, even irreparable destruction, to the glasses.

[0003] It is therefore an object of the present invention to provide improved spectacles that address the aforementioned problem. In particular, an improved embodiment of such spectacles is to be created in which the aforementioned problem no longer occurs.

[0004] This object is achieved by the subject matter of the independent patent claims. Preferred embodiments are the subject matter of the dependent patent claims.

[0005] The basic idea of ​​the invention is therefore to provide an over-tensioned position in spectacles in addition to the wearing position and stowed position, in which the temples can be locked laterally outwards from the frame. The temple in question is therefore adjusted to said over-tensioned position by moving it laterally outwards from the stowed position beyond the actual wearing position. Adjusting the temple beyond the wearing position therefore does not lead to damage to the temple or the frame due to over-tensioning of the temple relative to the frame. Uncontrolled adjustment of the temple from the over-tensioned position, in particular beyond the over-tensioned position away from the frame, is counteracted by the locking of the temple in the over-tensioned position, which is essential to the invention.The locking mechanism in the over-tension position also allows the wearer to initially maintain the set over-tension position or to selectively move the temple back to the wearing or stowed position. This significantly simplifies handling of the glasses. The result is a pair of glasses that avoids the risk of damage or even destruction to the temple or frame by adjusting or moving the temple too far outwards.

[0006] Following the inventive concept, a pair of spectacles according to the invention comprises a spectacle frame and two spectacle temples, each of which can be pivoted relative to the spectacle frame by means of at least one hinge, preferably each by means of two hinges. According to the invention, at least one spectacle temple can be locked in an over-tensioned position by means of the at least one hinge, in which the spectacle temple protrudes laterally outward from the spectacles or the spectacle frame, particularly in a plan view of the spectacles from above. Preferably, both spectacle temples of the spectacles can each be locked or locked in such an over-tensioned position.

[0007] In a preferred embodiment of the spectacles according to the invention, the spectacle frame extends along a frame longitudinal direction, and the at least one spectacle temple extends along a temple longitudinal direction. In this embodiment, the temple longitudinal direction and the frame longitudinal direction are arranged at an angle of more than 90°, preferably more than 180°, particularly preferably between 90° and 200°, to one another in the over-spanned position. In other words, the respective spectacle temple protrudes from the spectacle frame at the corresponding angle. The spectacle temple can thus be "over-spanned" relative to the spectacle frame in a permanent and mechanically stable manner without causing damage to or even destruction of the spectacles.

[0008] In a further preferred embodiment of the spectacles according to the invention, the spectacle frame has a temple attachment section extending at an angle, preferably substantially perpendicular to the longitudinal direction of the frame, for connection to the at least one temple. The temple attachment section can be bent relative to a main section of the spectacle frame, in which the spectacle lenses of the spectacles are also arranged. Typically, the temple attachment section is arranged at an angle of approximately 90° relative to the main section. However, slightly larger angle values ​​of up to 100°, up to 110°, or even up to 120° are also conceivable in variants.

[0009] In a further preferred embodiment, in the over-tensioned position, at least one of the temples is arranged outwardly, away from the other temple, at an angle, preferably at an acute or right angle, to the temple attachment section. In contrast, in the wearing position, the temple can be arranged in a straight extension of the temple attachment section. In the stowed position, the temple can be arranged at a substantially right angle to the temple attachment section.

[0010] Particularly preferably, in the over-clamping position, said angle between the temple fastening section and the temple can be an acute angle or a right angle or an obtuse angle.

[0011] According to an advantageous development of the spectacles according to the invention, a through-opening is formed in the temple attachment section. In this development, at least one temple has a fixing tongue on a temple end section facing the spectacle frame, which engages through the through-opening provided in the temple attachment section to fix the temple in the over-tightened position. In this way, the temple can be locked in the over-tightened position.

[0012] Particularly preferably, the fixing tongue can be designed to be resilient, particularly in the form of a leaf spring. This variant is particularly easy to implement technically and therefore also particularly cost-effective.

[0013] According to an advantageous development, the fixing tongue can be angled, in particular bent, inward toward the opposite temple in a tongue end section facing away from the at least one temple. Since the fixing tongue is rotated or pivoted relative to the temple end section when the temple is adjusted from the wearing position to the over-tensioned position, said angled design or geometry of the fixing tongue allows the through-opening to be designed comparatively small. Furthermore, the risk of injury is minimized when the temple is folded into the stowed position, in which the fixing tongue protrudes laterally outward from the spectacles. This makes it possible to dimension the above-described through-opening provided in the temple attachment section comparatively small.This in turn largely or even completely prevents the hair of a spectacle wearer from getting caught in the opening.

[0014] In a particularly preferred variant, in the over-clamping position, the locking tongue rests against an opening edge portion of the temple attachment section that delimits the through-opening away from the spectacle frame. This improves the locking of the temple in the over-clamping position in a technically simple manner.

[0015] Particularly preferably, the locking tongue can also be pre-tensioned toward the opening edge section in the over-tensioned position. In this way, the desired locking of the temple in the over-tensioned position is particularly effectively ensured.

[0016] According to a further advantageous development, the locking tongue has a recess in which the opening edge portion is received in the over-tensioned position of the temple. This measure also stabilizes the locking of the temple in question in the over-tensioned position.

[0017] In a further preferred embodiment of the spectacles according to the invention, the at least one temple and the spectacle frame are designed and coordinated in such a way that a predetermined minimum torque must be exerted on the temple to adjust the temple from the over-tightened position. This prevents the user or wearer from inadvertently adjusting the temple from the over-tightened position.

[0018] In another preferred embodiment, the at least one temple can be pivotable into a stowed position different from the over-tensioned position and into a wearing position provided between the stowed position and the over-tensioned position. In this embodiment, the fixing tongue extends through the through-opening provided in the temple fastening section in the over-tensioned position and also in the wearing position, but not in the stowed position.

[0019] In another preferred embodiment, two hinges are provided for each of the two temples. The two hinges are each pivotable about a common axis of rotation extending along a vertical direction perpendicular to both the frame's longitudinal direction and the temple's longitudinal direction. In this embodiment, the two hinges are spaced apart from one another along the vertical direction. Furthermore, in this embodiment, the fixing tongue is arranged, particularly in a sandwich-like manner, between the two hinges.

[0020] According to an advantageous further development, the passage opening can have the geometry of a rectangle with two narrow sides and two wide sides or the geometry of a square with four sides.

[0021] If the through-hole has a rectangular geometry, the length of at least one of the two broad sides of the rectangle shall be no more than 3.4 mm. If the through-hole has a square geometry, the length of at least one side of the square shall be no more than 3.5 mm.

[0022] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0023] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

[0024] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0025] They show, schematically: Fig. 1 an example of a pair of spectacles according to the invention, in which the temples are arranged in a wearing position, in a plan view from above, Fig. 2 the glasses of Fig. 1 in a side view from the left, Fig. 3 the in the Fig. 1 and Fig. 2 shown left temple of the glasses in a separate and enlarged view. Fig. 4 the glasses of Fig. 1 with the left temple in a stowed position, Fig. 5 the glasses of Fig. 1 with the left temple in an over-tightening position.

[0026] The Fig. 1 shows an example of a pair of glasses 1 according to the invention in a plan view from above. Fig. 2 shows the glasses of the Fig. 1 in a side view from the left.

[0027] According to the Fig. 1 and Fig. 2, the pair of spectacles 1 comprises a spectacle frame 2 with a main section 14 extending along a frame longitudinal direction FLR for accommodating two spectacle lenses 12, as well as two spectacle temples 3, each extending along a temple longitudinal direction BLR and located opposite one another in the frame longitudinal direction FLR. Thus, one of the two temples 3 is designed as the left temple 3l, and the other of the two temples 3 is designed as the right temple 3r, with respect to the top view of the spectacles 1.

[0028] For connection to the two temples 3l, 3r, the spectacle frame 2 has, in addition to the main section 14, a temple fastening section 5 each extending at an angle, preferably as shown in the example, essentially at a right angle, to the frame's longitudinal direction FLR. The main section 14 is thus arranged between the two temple fastening sections 5. The two temple fastening sections 5 and the main section 14 can be formed integrally with one another, i.e., formed in one piece and from the same material. In each of the two temple fastening sections 5, a through-opening 6 (cf. Fig. 2 for the temple fastening section 5) assigned to the left temple 3l. The through opening 6 can be Fig. 2 have the geometry of a rectangle 14 with two narrow sides and two wide sides, or the geometry of a square with four sides. If the through-opening 6 has a rectangular geometry, the length of at least one of the two wide sides of the rectangle 14 is at most 3.50 mm. If the through-opening 6 has the geometry of a square, the length of at least one side of the square is at most 2.55 mm.

[0029] Each of the two temples 3 is designed to be pivotable relative to the frame 2 by means of two hinges 4a, 4b. In the example, the glasses 1 therefore has a total of four hinges 4a, 4b. Both temples 3, i.e. both the left temple 3l and the right temple 3r, are designed to be pivotable about a common axis of rotation D by means of the two associated hinges 4a, 4b, which axis extends along a vertical direction HR. The vertical direction HR, in turn, extends perpendicular to both the frame longitudinal direction FLR and the temple longitudinal direction FLR. The two hinges 4a, 4b can be Fig. 2 shown along the vertical direction HR at a distance from each other.

[0030] Each of the two temples 3 is between a Fig. 1 and Fig. 2 shown carrying position, one in the Fig. 4 for the left bracket 3l and one in the Fig. 5 also shown for the left bracket 3l, pivotable and thus adjustable.

[0031] In the Fig. 1 and Fig. 2, the temple longitudinal direction BLR of the temple 3 and the frame longitudinal direction FLR of the frame 2 extend essentially orthogonally to each other. In the wearing position, the temple 3l can be arranged in a straight line extension of the temple fastening section 5. In the position shown in Fig. In the stowed position shown in Figure 4, the temple longitudinal direction BLR of the temple 2 and the frame longitudinal direction FLR extend essentially parallel to each other, thus forming no intermediate angle. In the stowed position, the temple 3l can be arranged at a substantially right angle β relative to the temple fastening section 5.

[0032] In the Fig. 5, the temple longitudinal direction BLR of the temple 3 and the frame longitudinal direction FLR of the frame 2 are at an angle α of more than 90°, thus also as in the example of Fig. 5, are arranged at an angle of approximately 180° to one another. Furthermore, in the over-clamping position, the left temple 3l is arranged outwards, away from the right temple 3r, at an angle to the temple fastening section 5. In the over-clamping position, the angle β formed between the temple fastening section 5 and the temple can be an acute angle (not shown) or a right angle (cf. Fig. 5) or an obtuse angle (not shown).

[0033] The two temples 3 and the frame 2 are designed and coordinated such that the temple 3 is locked relative to the frame 2 in the over-tensioned position. Such a locking of the temple 3 can also be provided in the wearing position and—alternatively or in addition to the wearing position—in the stowed position. To adjust the temple 3 away from the over-tensioned position, a predetermined minimum torque must be applied to the temple 3 in order to release the locking of the temple 3l in the over-tensioned position.

[0034] According to the figures, the two temples 3l, 3r have a fixing tongue 8 for pivotally connecting to the spectacle frame 2 on a respective temple end section 7 facing the spectacle frame 2. The fixing tongue 8 can be Fig. 2 sandwiched between the two hinges 4a, 4b The fixing tongue 8 is particularly in Fig. 6 clearly visible, which is a detailed representation of the Fig. 5 shows the glasses 1 at the transition from the frame 2 to the left temple 3l. According to the Fig. 5 and Fig. 6, the fixing tongue 8 passes through the through opening 6 provided in the temple fastening section 5 to fix or lock the temple 3 in the over-tensioned position.

[0035] The fixing tongue 8 can be designed to be resilient - for example, as a leaf spring 9. The fixing tongue 8 or the leaf spring 9 can be angled, in particular bent, in a tongue end section 13 facing away from the temple 3 inwards, towards the opposite temple 3 (cf. in particular Fig. 3).

[0036] As in particular the presentation of the Fig. 6, in the over-tensioned position shown, the fixing tongue 8 or the leaf spring 9 rests against an opening edge portion 10 of the temple fastening portion 5 that delimits the through-opening 6 away from the spectacle frame 2. The fixing tongue 8 or the leaf spring 9 can also be pre-tensioned toward the opening edge portion 10 in the over-tensioned position. Furthermore, the fixing tongue 8 or the leaf spring 9 can have a recess 11 in which the opening edge portion 10 is received when the temple 3 is in the over-tensioned position.

[0037] As the Fig. 1 and Fig. 5, the fixing tongue 8 extends through the through opening 6 provided in the bracket fastening section 5 not only in the over-tensioning position, but also in the carrying position.
