Description

Field of the invention

[0001] The invention relates to a spectacle hinge for pivotably fastening a spectacle temple to a spectacle frame of a pair of spectacles, as well as to spectacles with two spectacle hinges according to the invention, with which two spectacle temples are pivotably arranged on a spectacle frame of the spectacles. Background of the invention

[0002] It is known to arrange temples on a pair of glasses in a pivoting manner so that the temples can be folded onto the frame when the glasses are not in use.

[0003] To provide glasses in two different colors or different materials, it is necessary to provide two different pairs of glasses, each with a different color or material. This allows, for example, the wearer to wear the matching color pair depending on their outfit. The disadvantage of this approach, however, is that two different pairs of glasses must actually be provided for two different colors or materials.

[0004] To at least partially circumvent this disadvantage, it is known to provide glasses with so-called interchangeable temples. With these glasses, the temples can be removed and replaced with other temples. This allows a single frame to be combined with temples of different colors. However, at least two pairs of temples must be provided.

[0005] A type of interchangeable eyeglasses is known from DE 10 2016 101 370 A1. Here, the temples are attached to the frame via a special hinge. This hinge allows the temple to be pivoted over a range of approximately 360°. However, the disadvantage of this design is that it is not possible to reliably lock the temple in a specific position relative to the frame.

[0006] Three-part spectacle hinges are known from DE 20 2007 019 108 U1 and KR 101917985 B1, with the two other hinge elements being hinged to a central hinge element. Spring-loaded locking devices are arranged in the two other hinge elements and are pressed against the central hinge element.

[0007] US Pat. No. 5,751,393 A discloses a three-part eyeglass hinge, with the two other hinge elements being hinged to a central hinge element. The central hinge element has a through hole open on both sides, in which two locking devices and a spring acting on the two locking devices are arranged.

[0008] From DE 600 29 401 T2 a two-part spectacle hinge is known, wherein a spring-mounted locking means is arranged in one of the two hinge elements. Object of the invention

[0009] The object of the present invention is therefore to provide solutions which at least partially avoid the disadvantages known from the prior art and with which a pair of glasses can be provided whose temples can be securely locked to the frame. Inventive solution

[0010] According to the invention, this object is achieved with a spectacle hinge and a pair of spectacles according to the independent claims. Advantageous developments and refinements of the invention are specified in the respective dependent claims.

[0011] Accordingly, a spectacle hinge is provided for pivotably fastening a spectacle temple to a spectacle frame of a pair of spectacles, wherein the spectacle hinge - a first hinge element, - a second hinge element, and - a third hinge element includes, where - the first hinge element is pivotally connected to the second hinge element, - the first hinge element has at least one first resilient or resiliently mounted locking means, wherein the first locking means is arranged in the first hinge element so as to be movable along a movement axis, - the first locking means is pressed against the second hinge element by a spring force in a direction of movement along the movement axis, - the third hinge element is pivotally connected to the first hinge element, - the first hinge element has at least one second resilient or resiliently mounted locking means, wherein the second locking means is arranged in the first hinge element so as to be movable along a movement axis, - the second locking means is pressed against the third hinge element by a spring force in a direction of movement along the axis of movement, and - the at least one first locking means and the at least one second locking means are each arranged in a blind bore on the first hinge element.

[0012] By arranging the locking means in the first hinge element in a movable manner, wherein the locking means is movable along a movement axis, i.e. in a straight line, and the spring force with which the locking means is pressed against the second hinge element along the movement axis, a secure locking of the temple piece relative to the frame is ensured.

[0013] The three hinge elements are thus hinged to each other in pairs, i.e. hinge element ↔ hinge element ↔ hinge elements, where "↔" means hinged. In a three-part eyeglass hinge, one hinge element forms a "middle" hinge element.

[0014] In one embodiment of the invention, it may be advantageous if each hinge element can be pivoted relative to the respective hinge element by a range of at least 160°, preferably at least 180°. For example, the second (or third) hinge element pivoted to the first hinge element can be pivoted by an angle of at least 160° relative to the first hinge element.

[0015] In a three-part spectacle hinge (with a first, a second and a third hinge element), a temple can be pivoted by at least 320°, preferably by 360° relative to the spectacle frame - a temple can be pivoted and folded to a first side of the spectacle frame and to a second side of the spectacle frame, so that either one side of the spectacle frame or the other side of the spectacle frame can be used as the front.

[0016] By arranging the locking devices in a separate blind hole, a secure positioning of each locking device can be ensured. In particular, this ensures a linear movement of the respective locking device within the hinge element. By adapting the geometry of the blind hole to the geometry of the locking device, contamination of the locking device, which could lead to functional impairment, can be largely avoided.

[0017] It may be advantageous if the at least one first locking means and the at least one second locking means each comprise a piston and a spring element that interacts with the respective piston. The spring element may comprise a compression spring, preferably a helical compression spring. The spring element may be adapted to push the respective piston out of the respective blind bore in the direction of movement along the movement axis.

[0018] In one embodiment of the invention, the spring element of the at least one first locking means can have a different spring force than the spring element of the at least one second locking means. It is advantageous in this case if the spring element of the locking means that presses against the hinge element assigned to the temple has a greater spring force than the spring element of the locking means that presses against the hinge element assigned to the frame. This ensures optimal functionality of the three-part hinge, i.e. it ensures that the temple can be folded or pivoted from one side of the frame to the other side of the frame without the temple being pivoted relative to the central hinge element during this pivoting process.

[0019] Alternatively, the spring force of the spring elements can be identical or essentially the same.

[0020] In one embodiment of the invention, two hinge elements can be pivotally connected to one another via a hinge fork-hinge web connection, wherein one of the two hinge elements has the hinge fork and the other of the two hinge elements has the hinge web.

[0021] The second hinge element can be coupled, in particular detachably coupled, to the temple and / or the third hinge element can be coupled to a spectacle frame.

[0022] In one embodiment of the invention, it can be advantageous if the second hinge element is designed as a single piece with the temple and / or the third hinge element is designed as a single piece with the frame. “Single piece” means that the hinge element and the temple (or frame) are designed as a single piece, i.e. the hinge element is an integral part of the temple (or frame). This can be particularly advantageous if the frame and / or temple are manufactured using a 3D printing process. Of course, even with the aforementioned single-piece design, the locking means are arranged so as to be movable in the respective hinge element.

[0023] The invention further provides a pair of spectacles comprising a spectacle frame, two spectacle temples and two spectacle hinges according to the invention, wherein each spectacle temple is pivotally arranged, i.e. hinged, on the spectacle frame via a spectacle hinge according to the invention.

[0024] It is advantageous if each temple piece can be pivoted relative to the frame via the respective hinge over a range of at least 320°, preferably at least 360°.

[0025] The frame, temples, and / or hinges can be manufactured using a 3D printing process. Alternatively, the frame, temples, and / or hinges can be manufactured using a machining process or an injection molding process.

[0026] The three-part spectacle hinge according to the invention or the spectacles according to the invention provide so-called "interchangeable spectacles" that combine two pairs of spectacles in one pair. By pivoting the temples relative to the spectacle frame, the inside of the spectacles can be converted into the outside of the spectacles. Due to the inventive design of the spectacle hinge, which is arranged between the spectacle frame and the temple, the temple can be pivoted by up to 360° relative to the spectacle frame, with 180° of the pivoting movement being accomplished via the hinge element assigned to the spectacle frame and 180° of the pivoting movement via the hinge element assigned to the temple. As a result, the temple is pivoted from one side of the spectacles to the other side of the spectacles or the spectacle frame. Short description of the characters

It shows: Fig. 1 in figure (a) a section of a pair of spectacles according to the invention (part of a spectacle frame with a temple piece arranged thereon), and in figure (b) an enlarged view of the spectacle hinge shown in figure (a); Fig. 2 shows an embodiment of a first hinge element (hinge housing) of a spectacle hinge according to the invention, wherein figure (a) shows a perspective view of the hinge housing, figure (b) shows a side view of the hinge housing with several cutouts, and figure (c) shows a top view of the hinge housing; Fig. 3 an alternative embodiment of a first hinge element (hinge housing) of a spectacle hinge according to the invention in a side view with several cutouts (Figure (c)) and a locking means (Figure (a)) with a spring element associated with the locking means (Figure (b)); Fig. 4 a joint part (second or third hinge element) of a spectacle hinge according to the invention in a view from above (figure (a)) and a side view with a cutout (figure (b)); Fig. 5 in Figure (a) the Fig. 2 shows a longitudinal section of the hinge housing (first hinge element) with hinge parts (second and third hinge elements) hinged thereto, and figures (b) and (c) each show a cross section of a part of the hinge housing with a hinge part hinged thereto; Fig. 6 in figures (a), (b), (c) and (d) four alternative designs of a spectacle hinge; and Fig. 7 shows a further embodiment of spectacles according to the invention. Detailed description of the invention

[0028] Fig. 1 shows in figure (a) a section of a pair of spectacles 1 according to the invention and in figure (b) an enlarged view of the spectacle hinge 20 shown in figure (a). The spectacles 1 comprise a spectacle frame 2 and two spectacle temples 10, wherein the two spectacle temples 10 are each pivotally connected to the spectacle frame 2 via a spectacle hinge 20 according to the invention.

[0029] At the Fig. In the spectacles 1 according to the invention shown in Figure 1, the temples 10 can be pivoted from one side of the spectacle frame 2 to the other side of the spectacle frame 2, so that the inner side 2b of the spectacle frame 2 can be converted into the outer side. The outer side 2a of the spectacle frame 2 then becomes the inner side of the spectacle frame.

[0030] If both surfaces 2a, 2b of the spectacle frame 2 each have a different color and / or a different material, then the spectacles 1 according to the invention provide so-called interchangeable spectacles, the color and / or material of which can be changed by pivoting the temples 10 to the other side of the spectacle frame 2.

[0031] The eyeglass hinge 20 is designed in three parts and comprises a first hinge element 30, which is also referred to below as the hinge housing 30, a second hinge element 40a, and a third hinge element 40b. The second hinge element 40a and the third hinge element 40b are also referred to below as the joint part 40a and the joint part 40b, respectively.

[0032] At the Fig. In the embodiment of the spectacle hinge 20 according to the invention shown in Figure 1, the first joint part 40a is pivotally mounted on one end face of the hinge housing 30. The second joint part 40b is pivotally mounted on the opposite end face of the hinge housing 30. The hinge housing 30 is configured here on both end faces as a hinge fork, into which a hinge pin of the corresponding joint part engages. The joint parts 40a, 40b are pivotally attached to the respective end face of the hinge housing 30 or to the respective hinge fork via fastening means 41a, 41b, which can be configured as screws or bolts.

[0033] The fastening means 41a, 41b each form a pivot axis DA1 and DA2.

[0034] The second joint part 40b is arranged on the spectacle frame 2, so that the hinge housing 30 can be pivoted relative to the spectacle frame 2 through a range of at least 160°, preferably through a range of approximately 180°, about the pivot axis DA1. The hinge housing 30 can thus be oriented either toward one side of the spectacle frame or toward the other side of the spectacle frame.

[0035] The first joint part 40a is arranged on the temple piece 10, so that the first joint part 40a can be pivoted about the pivot axis DA2 relative to the hinge housing 30 through a range of at least 160°, preferably through a range of approximately 180°. The temple piece 10 can thus be pivoted inward on both sides of the frame 2 (depending on which side of the frame the hinge housing is oriented toward), i.e., toward the frame (for example, when the glasses are not in use).

[0036] The two pivot axes DA1 and DA2 thus make it possible to pivot the temple 10 through a range of at least 320°, preferably of approximately 360°, relative to the frame.

[0037] The hinge housing 30 and the two joint parts 40a, 40b can be made of a plastic or a metal.

[0038] The joint part 40a can be made in one piece with the temple 10. In Fig. 1, however, shows a two-part variant of the temple 10 and the joint part 40a, in which the joint part 40a is fastened to the temple by means of fastening means.

[0039] The joint part 40b can be manufactured in one piece with the spectacle frame 2. In Fig. 1, however, shows a two-part variant of the spectacle frame 2 and the joint part 40b, in which the joint part 40b is fastened to the spectacle frame by means of fastening means.

[0040] In one embodiment of the invention, the two joint parts 40a, 40b can be designed identically, ie a joint part can be used both on the spectacle frame side and on the temple side.

[0041] The hinge 20 according to the invention provides locking means that securely lock the temple 10 in the use position (as shown in Figure (a)) on the one hand and in the folded position (when the glasses are not in use) on the other. This locking mechanism is described in more detail below.

[0042] Fig. 2 shows an embodiment of a hinge housing 30 of a spectacle hinge according to the invention, wherein figure (a) shows a perspective view of the hinge housing 30, figure (b) shows a side view of the hinge housing with several cutouts, and figure (c) shows a top view of the hinge housing 30.

[0043] The hinge housing 30 has a hinge fork 31a and 31b on each end face, into which a hinge web of the joint parts 40a, 40b can be engaged. The hinge forks each have a through-hole 32 through which fastening means 41a, 41b can be pushed to fasten the respective joint part to the hinge housing. Fastening means 41a, 41b received in the holes 32 are Fig. 1 shown.

[0044] The fastening means 41a, 41b each form a pivot axis DA1 or DA2, about which the respective joint part 40a, 40b can be pivoted relative to the hinge housing 30.

[0045] The two boreholes 32 run at the Fig. 2, the hinge parts 40b are not parallel to each other, but rather at a specific angle to each other. This allows, for example, the hinge part 40b on the frame side to be arranged on the pivot axis DA1, so that the temple 10 is inclined at this specific angle relative to the frame.

[0046] An alternative design in which the two boreholes 32 run parallel to each other is shown in Fig. 3, Figure (c).

[0047] Four blind holes 35 are provided in the hinge housing 30, each of which serves to accommodate a locking device. The blind holes or blind bores 35 each open in the front area of ​​the hinge housing between the two hinge forks 31a, 31b, with two blind holes being assigned to the hinge fork 31a and two blind holes to the hinge fork 31b.

[0048] In one embodiment of the invention, only two blind holes can be provided (each hinge fork 32 of the hinge housing 30 is then assigned a blind hole 35). This means that two locking means are arranged in the hinge housing 30, with one locking means pressing against one joint part and the other locking means pressing against the other joint part.

[0049] The longitudinal axes of the blind holes 35 each run essentially perpendicular to the respective pivot axis DA1, DA2. This ensures that the locking means arranged in the blind holes 35 are moved perpendicular to the respective pivot axis DA1, DA2 and thus perpendicular to the respective joint part 40a, 40b. The direction of movement BR of the locking means is in Fig. 2 are indicated by an arrow BR.

[0050] As shown in Figure (c) of the Fig. As can be seen in Figure 2, the blind holes assigned to the hinge forks 31a can be offset from the blind holes assigned to the hinge forks 31b. However, this is only optional. Whether such an offset is necessary may depend on the specific design of the joint parts accommodated by the hinge forks.

[0051] Fig. 3 shows an alternative embodiment of a hinge housing 30 of a spectacle hinge according to the invention in a side view with several cutouts (Figure (c)) and a locking means 36a, 36b (Figure (a)) with a spring element 37 associated with the locking means (Figure (b)).

[0052] Figure (c) of the Fig. Figure 3 shows a hinge housing 30 with a locking means 36a, 36b arranged relative to the hinge housing 30. The locking means 36a, 36b and the hinge housing 30 are shown here in the unassembled state. For assembly, the locking means is guided along the Fig. 3 (c) into the blind hole 35. The joint part is then inserted into the hinge fork 31a and secured with a fastening screw 41a. The locking device can then no longer be removed from the blind hole 35.

[0053] The locking means 36a, 36b is designed here as a rotationally symmetrical body (e.g. bolt or piston) which can be arranged in the blind hole 35 so as to be movable along its longitudinal axis.

[0054] The locking means is associated with a spring element 37, which is configured and arranged relative to the locking means in the blind hole 35 in such a way that the locking means is subjected to a spring force by the spring element. The spring force and the direction in which the spring force acts are selected such that the locking means (such as a bolt) is pressed out of the blind hole 35 and against the joint part, which is received in the hinge fork. The force with which the locking means is pressed against the joint part locks the joint part to the hinge housing.

[0055] In the Fig. In the configuration shown in Figure 3, the spring element 37 is designed as a compression spring, specifically a helical compression spring. However, other spring types, such as disc springs, can also be used.

[0056] Fig. 4 shows a joint part 40a, 40b (second and third hinge element, respectively) of a spectacle hinge according to the invention in a view from above (Figure (a)) and a side view with a cutout (Figure (b)).

[0057] The joint part has a fastening section 42, which is designed here such that it can be received in a recess in the spectacle frame or the temple. Drill holes 44 are provided on an edge-side projection of the fastening section 42 for receiving fastening screws with which the joint part is fastened to the spectacle frame or the temple. Alternatively, the joint part or the fastening section 42 can also be glued in the recess in the spectacle frame or the temple - in this case, the drill holes 44 can also be omitted. In a further alternative, it can also be provided to fasten the joint part to the spectacle frame or the temple by means of a press fit or by welding.

[0058] In a further alternative embodiment of the invention, the fastening section 42 can have an external thread, so that the joint part can be attached to the spectacle frame or the temple by screwing it to the spectacle frame or temple. The spectacle frame or temple has a borehole with an internal thread corresponding to the external thread.

[0059] The hinge part further comprises a hinge web 45a, 45b adapted to be received in the hinge fork of the hinge housing. The hinge web has a borehole or through-hole 43 which, when the hinge web is received in the hinge fork of the hinge housing, runs coaxially with the borehole 32 of the hinge fork. The fastening means 41a, 41b received in the borehole 32 is pushed through the through-hole 43, so that the hinge part is pivotally connected to the hinge housing. The fastening means 41a, 41b then forms the pivot axis.

[0060] At the free end of the hinge web 45a, 45b, an edge-side projection 46 can be provided, which is approximately bead-like and runs parallel to the through hole 43. This edge-side projection 46 can be provided on both sides of the hinge web. The edge-side projection 46 ensures secure locking of the joint part to the hinge housing in a predetermined position of the joint part relative to the hinge housing.

[0061] Such a position of the joint part relative to the hinge housing is, for example, in Fig. 5, Figure (b). There, the edge-side projection 46 requires a certain force to be applied in order to pivot the joint part 40b about the pivot axis DA1 from the position shown there.

[0062] Fig. 5 shows in Figure (a) the Fig. 2 shows a longitudinal section of the hinge housing (first hinge element) with hinge parts (second and third hinge element) hinged thereto, and in figures (b) and (c) each show a cross section of a part of the hinge housing with a hinge part hinged thereto.

[0063] Figure (a) shows the Fig. 2, wherein the joint parts 40a and 40b hinged to the hinge housing 30 as well as the locking means received in the blind holes 35 are also shown. The joint parts are each fastened to the hinge housing 30 by means of fastening screws 41a, 41b.

[0064] Figure (b) shows a cross-section of the right-hand part of the hinge housing 30 shown in Figure (a). The joint part 40b is positioned essentially at a right angle to the hinge housing 30. The locking element 36b is pressed by the spring element 37 out of the blind hole 35 (along the movement axis BA and in the movement direction BR) and laterally against the hinge web 45b of the joint part 40b. Since the lateral section of the hinge web 45b and the end face of the locking element 36b are essentially flat, reliable locking is ensured.

[0065] The projection 46 on the edge of the hinge web 45b has the purpose that a certain force must be applied in order to be able to pivot the locking means 36b out of the position shown in Figure (b).

[0066] Figure (c) shows a cross-section of the left part of the hinge housing 30 shown in Figure (a). The joint part 40a is here essentially perpendicular to the front side of the hinge housing 30. The function of the joint part 40a and the locking means 36a essentially corresponds to the function as explained with reference to Figure (b).

[0067] Fig. 6 shows in figures (a), (b), (c) and (d) four alternative embodiments of a spectacle hinge, the embodiments according to figures (b) and (c) not being embodiments according to the invention.

[0068] In contrast to the spectacle hinge described above, the hinge housing 30 according to figures (a) and (b) has a hinge web 45a, while the joint part 40a has a corresponding hinge fork 31a.

[0069] According to Figure (a), the locking means (not shown here) are arranged according to the invention in blind holes 35 of the hinge housing 30, wherein the blind holes are provided in the hinge housing such that the locking means act on the hinge fork 31a. It is also possible to provide only one of the two blind holes 35 shown here.

[0070] In an embodiment not according to the invention and as shown in Figure (b), the locking means (not shown here) can also be arranged in blind holes 35 of the joint part 40a, whereby only one blind hole is shown here. Two or more blind holes can also be provided. The blind hole shown here is provided in the joint part 40a such that the locking means acts on the hinge web 45a of the hinge housing 30.

[0071] In a non-inventive embodiment and according to Figure (c), the hinge housing 30 has a hinge fork 31a, while the joint part 40a has a corresponding hinge web 45a. The hinge housing and joint part thus have essentially the same shape, as in Fig. 1 to Fig. 5. In contrast to the Fig. 1 to Fig. In the spectacle hinge shown in Figure 5, the locking means are arranged in blind holes 35 of the hinge part 40a, with the blind holes each arranged such that one locking means acts against one part of the hinge fork and the other locking means against the other part of the hinge fork. Alternatively, it is also possible to provide only one blind hole with a corresponding locking means.

[0072] Figure (d) shows a hinge housing 30 and a hinge part 40a of a hinge according to the invention, which is connected thereto. A blind hole 35 is provided in each of the hinge housing 30 and the hinge part 40a for receiving a locking device. Only one of the two blind holes shown here may also be provided.

[0073] Fig. 7 shows the Fig.1 shows a pair of glasses with an alternative design of the hinge 20. The hinge 20 here has a hinge housing 30 and a joint part 40a hinged to the hinge housing 30. The joint part 40a is attached to the temple 10, while the hinge housing 30 is attached to the frame 2. Thus, a two-part hinge is shown here, not according to the invention. The functionality corresponds to the three-part hinge described above. The only difference from the three-part hinge is that the temple cannot be pivoted by up to 360° relative to the frame.
