Glasses hinge

The invention relates to a spectacle hinge consisting of two Hinge parts, which by means of a joint around an axis (swivel axis) are pivotally connected to each other o

The most delicate part of a spectacle frame in terms of how it works or a pair of glasses are known to be the articulation of the temple on the Hinges used for the middle part of the glasses »The hinge used to date consist of two hinge parts, one of which is on the The middle part of the glasses and the other is attached to the temple and the have one or more hinge tabs with congruent holes, wherein the hinge tabs by means of one through the bores of these hinge tabs extending through and serving as a hinge pin screw are articulated together. The screw is in one Threaded hole of a hinge tab screwed in, with corresponding Tightening the screw a certain stiffness of the spectacle hinge can be achieved by friction between the hinge tabs should, so that the eyeglass temple hinged with the eyeglass hinge can still be opened comfortably, but the eyeglass temple cannot by itself falls from the unfolded position to the folded position and vice versa. However, the known hinges for glasses have the disadvantage that the screw serving as a pivot pin ή by pivoting over time of the temple so that there is no swinging of the temple at all more is possible, or loosens to the extent that the desired The friction between the hinge parts is lost and the temple in question increases "Fall" begins or the screw serving as a hinge pin finally falls out and thus the connection between the middle part of the glasses and is completely lost from the relevant roaring bracket.

030034/046?

2905516

Attempts have already been made to overcome these disadvantages of known spectacle hinges thereby avoiding / that to increase the friction between the hinge parts and to reduce the friction between the hinge parts and the screw serving as a hinge pin in the hinge tab Plastic bushings or plastic sleeves are injected and / or inserted · Even with these measures, undesired loosening can be achieved or tightening the screw not avoiding what's in the The rest also applies if the screws are secured with additional nuts or paint or other adhesive materials.

For this reason, the screw must be used in the known hinge for glasses relatively often tightened or the gear of the spectacle hinge adjusted again by turning the screw, with the result that the thread, which has only a few threads and is usually provided on a hinge tab on the temple, tears out, so that a further tightening or adjustment of the screw is no longer possible at all, whereby the entire temple is worthless and against a new bracket needs to be replaced.

The object of the invention is to overcome the disadvantages of known spectacle hinges to avoid and to show a spectacle hinge in which the articulated connection or the joint between the two hinge parts is realized without using a hinge pin and in particular also without using a screw serving as a hinge pin.

To solve this problem, a spectacle hinge of the type described is designed according to the invention so that the joint of a of the one hinge part comprised joint head is formed on the other hinge part, and that the joint head on at least one transverse to The pivot axis of the hinge running first bearing surface, a rotationally symmetrical to this pivot axis and the raised portion

030034/0 46 7

the hinge part encompassing the articulated head on one against this first loger surface adjacent first mating surface a receiving the increase and with this indentation of the same shape, or vice versa, have »

The articulated connection between the two hinge parts of the spectacle hinge according to the invention is therefore exclusively, dob. without use a special hinge pin produced in that the joint head on at least one transverse to the pivot axis of the spectacle hinge running bearing surface has an elevation which lies in a corresponding depression of a counter surface with which the joint head overlaps further hinge part rests firmly against the bearing surface of the joint head »This not only ensures that the required mobility of the glasses hinge generates the necessary frictional forces between the two hinge parts, but at the same time it is also ensured that the hinge parts are relative to the imaginary pivot axis are movable or pivotable relative to one another, but a separation of these hinge parts is not easily possible. The increase in the storage area of the joint head or the recess on the opposite surface of this The joint head overlapping hinge part are preferably thereby produces that the bearing surface on the joint head is convex and the mating surface on the hinge part overlapping the joint head is correspondingly concave are. It is of course also possible with the spectacle hinge according to the invention that the bearing surface on the joint head is reversed a recess and the mating surface on the hinge part overlapping the joint head have or form a corresponding elevation.

Unwanted tightening or loosening of a hinge pin Screw cannot occur in the spectacle hinge according to the invention, so that this spectacle hinge is fully functional even after prolonged use remain.

03ÜÜ34 / 0 46 7

Furthermore, in the case of the spectacle hinge according to the invention, the design and shaping of the elevation or depression as well as the contact pressure between the bearing surface and the opposing surface are coordinated with one another / that with normal use of glasses, the connection between the parts of the glasses hinged to one another with the glasses hinge according to the invention is not lost, however, in the event of overloads, e.g. in the event of external impacts on the glasses frame, the joint head from the hinge part surrounding it pops out, as a result of which the parts of the glasses and, in particular, the temple of the glasses are prevented from breaking in the event of excessive loads (external impacts) is, in which case the goggle hinge in its function by pressing the joint head into the hinge part overlapping this joint head is fully restored.

By the described jumping out of the joint head when overloaded Not only material damage to the glasses or the glasses frame is avoided, but at the same time the risk of possible injuries is also increased sharp edges of broken glasses are greatly reduced.

In the case of the spectacle hinge according to the invention, the joint head has protrusions two opposing bearing surfaces running perpendicular to the pivot axis of the spectacle hinge / those against two opposing surfaces of the hinge part overlapping the joint head. Both bearing surfaces as well as counter surfaces are with the mentioned elevations or Provide indentations.

Furthermore, the bearing head in the spectacle hinge according to the invention has preferably a second bearing surface running concentrically to the pivot axis, against a second counter-surface of the hinge part that overlaps the bearing head and that also runs concentrically to the pivot axis is present.

290b516

The joint head is preferred in the hinge according to the invention disk-shaped with a circular circumferential surface, wherein then the two end faces or flat sides of this disk-shaped joint head Form the first storage areas with an elevation or a depression.

In a preferred embodiment of the spectacle hinge according to the invention the joint head or the hinge part having this joint head is made of metal, while the one that overlaps the joint head Hinge part made of plastic, preferably made of tough or elastic plastic, the inherent elasticity of the plastic material determines the contact pressure with which the first bearing surfaces and mating surfaces bear against one another. However, it is also possible here to provide special means by which these pressing forces are determined or the pressing of the first mating surfaces against the first bearing surfaces support or additionally secure the two hinge parts of the spectacle hinge according to the invention to one another. In the simplest case these means consist of a cap which, after the hinge parts have been connected to one another, is placed on the hinge part that engages the joint head is pushed on, this cap then overlapping the joint head The hinge part or the corresponding wall section of this hinge part presses firmly against the joint head.

In a further development of the invention it is provided that the joint head overlapping hinge part has a recess which is rotationally symmetrical to the pivot axis of the spectacle hinge, i.e. for example, has an inner wall surface which runs concentrically to this pivot axis and which serves as a second counter surface, and two perpendicular has inner end walls which extend to the pivot axis and which form the first opposing surfaces. This recess is through an opening for insertion of the joint head accessible, whereby to connect the joint head with

030034/0 467

a part of a pair of glasses passed through this opening approach of the Joint head is used.

In the case of the glasses hinge according to the invention, the fastening takes place preferably of the hinge part overlapping the joint head on a goggle part, preferably in that on this hinge part as well an approach is provided, which is in a hole on the relevant Anchoring body that can be attached to the lens part, e.g. a fastening sleeve can be introduced. Locking means are provided. With these latching or locking means, the approach is secured when it is inserted into the hole, that pulling out the approach is only possible when overcoming a certain force, while at the same time provided with a circular cross-section Approach is rotatable about its longitudinal axis in the bore. This had the advantage that the parts of the glasses connected to the hinge E.g. the middle part of the glasses and temple pieces when processing the glasses frame, e.g. during coating, painting, dyeing, etc. can be twisted against each other, which was previously only possible by bending or deforming the Hinge parts was possible. Only after the surface treatment of the eyeglass parts is the approach in the bore, for example, used a corresponding adhesive (two-component adhesive) finally determined.

Of course, the mentioned approach and the associated hole also be designed / that already after the insertion of the approach in the bore a torsion-proof and positionally accurate hold of the relevant hinge part can be obtained. In this case, the approach and de This approach receiving bore, for example, a cross-section deviating from the circular shape or are with interlocking longitudinal grooves and bars *

The hinge part 3 consists essentially of the joint head 12, the in the embodiment shown is designed as a circular disk-shaped plate which is rotationally symmetrical on its two flat sides 25 is formed convexly curved to the axis of the circular disk-shaped plate and thus rotationally symmetrical to the pivot axis of the spectacle hinge. The radius of the circular disk-shaped plate or of the joint head 12 corresponds to the radius of the inner surface 10 of the recess 9 of the hinge part 1, while the curvature of the flat sides 25 is equal to the curvature of the Side surfaces 11 of the recess 9 is. The distance between the flat sides 25 is slightly greater than the distance between the flat sides 25 both side surfaces 11 of the recess 9.

On the joint head 12 or on the circular disk-shaped plate forming this joint head 12, a projection 26 is formed on the circumference, which in the embodiment shown has a square cross-section in the manner that two surface sides of this approach parallel to the axis of the joint head 12 and two surface sides perpendicular to the axis of the joint head 12 are * At the end facing away from the joint head 12 is the shoulder 26 a plate 27 is formed, which is used to attach the hinge part 3 to the bracket insert 5 serves · Just like this bracket insert 5 is the hinge part 3 including the joint head 12, the extension 26 and the Plate 27 made of metal * The attachment of the hinge part or the plate 7 on the bracket insert 5 is carried out by suitable means, such as welding, soldering or gluing *

As an optical cover for the head 6 and to ensure sufficient contact pressure for the side surfaces 11 on the preferably polished flat sides 25 of the joint head 12, the spectacle hinge shown also has a cap or fixing cap 28 that can be pushed onto the head 6 and accordingly two flat ones or has curved wall parts 29 corresponding to the sides 7, which have a

830G34 / G467

- ytr-

curved wall part 30 are connected to one another. These fixing caps 28 is preferably made of metal.

For the articulated connection of the hinge parts 1 and 3, the joint head introduced through the opening 13 into the recess 9, with this Introduce both the longitudinal sides 16 of the opening 13 and the wall parts of the head 6 forming the sides 7 from the flat sides 25 first are printed to the side / until after the final insertion of the joint head 12 dL e flat sides 25 come to rest in the concave depressions on the side surfaces 11 of the recess 9. The distance that the Have flat sides 25 from one another / it is ensured that the side surfaces H also after the insertion of the joint head 12 into the recess 9 rest against the flat sides 25 of the joint head 12 with a certain pressure / whereby the joint head 12 on the one hand is secured against undesired slipping out of the opening 9 and on the other hand the necessary Braking effect when pivoting the hinge parts 1 and 3 relative to each other is obtained. After inserting the joint head 12 into the recess is for the final securing of the hinge parts 1 and 3 to each other, the fixing cap 28 is pushed laterally onto the head 6, the wall parts 29 with a press fit Gegei the pages 7 rest. The opening 13 also remains after placing the fixing cap 28 free / so that the in this Opening 13 lying approach 26 can move freely when pivoting the hinge in the longitudinal direction of the opening 13. If necessary, the fixing cap 23 can additionally be attached to the head 6 by using a suitable adhesive secured.

For example, when attaching the hinge to the parts of the glasses, the procedure is as follows:

If the eyeglass middle part 2 is made of plastic, the sleeve 7 is also their closed end inserted into a bore 31 of the middle part 2 and there in a suitable manner, for example below

030034/0 4 67

Use of an adhesive, e.g. a two-component adhesive anchored in such a way that the opening 18 remains freely accessible for inserting the projection 9. It is also possible here to anchor the sleeve 17 through Swim in to carry out ultrasound. By the in the groove 19 at Anchoring penetrating material (glue or material of the middle part of the glasses 2) a non-rotatable mounting of the sleeve 19 is achieved.

Waterhin it is of course also possible to use the sleeve 17 directly to encapsulate with the material of the eyeglass middle part 2 or to integrate it into a metal frame, which is particularly the case in whole or in part made of metal eyeglass middle parts is advantageous. In this case, the shape of the sleeve 17 can of course match the design The metal frame can be adapted, i.e. it is ultimately also possible to use a non-sleeve-shaped body instead of the sleeve 17 an opening 18 to be used.

For glasses frames that do not require any further processing, such as dyeing or Make coating with lacquer necessary, an adhesive, for example a two-component adhesive, is introduced into the opening 18 of the sleeve 17 and Following this, the projection 8 is introduced into the opening 18 and possibly rotated in this opening so that the hinge part 1 is opposite the middle part of the glasses 2 has the necessary position, i.e. the opening 13 for Side of the eyeglass middle part 2 is directed towards. Through the slot 22, the adhesive is evenly in the opening when the projection 8 is pressed in 18 distributed. At the same time the glue gets into the grooves 23 and 24, so that after the adhesive has hardened, an intimate connection between the sleeve 17 and the projection 8 is established. For completing the glasses frame the eyeglass temples provided with the hinge parts 3 by inserting the joint heads 12 into the recesses of the hinge parts attached to the middle part 2 of the glasses, this attachment after the slide the fixing caps 28 on the heads 6 of the hinge parts 1 completed is.

03003 4/046 7

730651S

Is further processing of the glasses or the glasses frame, e.g. Dyeing or layering of the middle part 2 and / or the temples 4 required, the approaches 8 of the hinge parts 1 are not used an adhesive is introduced into the openings 18 of the sleeves 17 in such a way that the projections 21 of these lugs snap into place behind the edges 20 of the sleeve 17 in question. Subsequently, in the manner described above, the temples 4 are inserted by inserting the joint heads fastened in the recesses 8 on the middle part 2 of the glasses. Now the further processing of the glasses or the glasses frame, such as dyeing or Coating with lacquer, take place, with this further processing the hinge parts 1 and thus also the temples 4 without the use of weight can be rotated relative to the middle part 2 of the glasses.

As soon as the further processing of the glasses or the glasses frame has been completed, the attachments 8 are pulled out of the sleeve 17 again, whereupon an adhesive is introduced into the openings 18 the final anchoring of the hinge parts 1 in the associated Sleeves 17 and then pushing on the fixing caps 28 takes place.

If it turns out after the processing of the glasses that the hinge parts 1 are soiled during this processing, these soiled hinge parts can be used before they are glued to the sleeves 17 without Difficulties exchanged for hinge parts that are not dirty will.

The contact pressure with which the side surfaces 11 against the flat sides 25 of the joint head 12 rest is preferably set in the inventive hinge so that when a force is used on Eyeglass temple 4 the connection or snap connection between the coulter * kidney parts 1 and 3 detach or the joint head 12 from the recess 9

030034/0 / «67

emerges, so that breaking of the temple 4 and thus also sharp break points are avoided, which could lead to injuries. By pressing the joint head 12 into the associated recess 9 , the respective temple piece 4 can again be attached to the central part 2 without difficulty when high external forces occur, there is no risk of injury from the hinge part 3.

Ourch the production of the hinge part 1 from plastic and by the Using the joint head 12 with preferably polished flat sides 25 is a permanent and smooth movement of the spectacle hinge over guaranteed for a long time. If it turns out that the spectacle hinge becomes too easy to move in the course of time due to wear and tear, With the aid of a suitable tool, for example with the aid of pliers, the fixing cap 28 can be deformed by pressure on the wall parts 29 in such a way that the side surfaces 11 in turn sufficiently firmly against the flat sides 25 of the joint head 12 and thus the desired mobility of the spectacle hinge is restored.

Should, in spite of the safeguarding against overloading the Hinge part 1 break anyway, so this hinge part can at any time can be replaced by a new hinge part 1 without difficulty.

The pivoting range of the spectacle hinge shown is limited by that the approach 26 finds a stop on the transverse side 14 when the bracket is fully opened and on the transverse side 15 when the bracket is fully closed. However, this is not absolutely necessary, i.e. the length

03 0034/04 67

ir-

the slot-shaped opening 13 can also be selected so that the opened and / or closed spectacle temple 4 on the middle part 2 of the glasses strikes.

Furthermore, the width of the slot-shaped opening 13 is preferable so matched to the cross section of the projection 26 that this approach finds a guide on the longitudinal sides 16 of the opening 13, whereby the Strength of the glasses hinge is reinforced,

Oa the cross-sectional dimensions of the joint head 12 in the direction of The pivot axis of the spectacle hinge is significantly smaller than the cross-sectional dimensions perpendicular to this pivot axis / has that Spectacle hinge also provides adequate security against undesirable Pivoting the roaring bracket 4 about an axis running transversely to the pivot axis, i.e. the glasses hinge also offers a sufficient one Resistance to torques that act around such an axis running transversely to the pivot axis.

The invention was described above using an exemplary embodiment. It goes without saying that changes and modifications are possible without departing from the idea on which the invention is based. In particular, it is also possible to also manufacture the hinge part 1 from metal, in which case the side surfaces 11 of the recess 9 and / or the flat sides 25 of the joint head 12 have a coating made of plastic. If the hinge part 1 is made of metal is, this has in the area of the concentric to the pivot axis and serving as a contact or guide surface for the circumference of the joint head 12 inner surface 10 a continuous slot that a

resilient evasion of the two, the sides 7 determining wall parts of the Head 6 permitted when the joint head 12 is imported.
