Description

AT 004100 Ul

The present invention relates generally to eyeglass frames and, in particular, to such a new, improved design for accommodating glasses which can be replaced without tools according to the preamble of claim 1. The improvement relates to the position, arrangement and functional actuation of the clamping device, by means of which the assembly state is determined in a quick and simple manner without tools or can be solved.

Spectacle frames of the type which allow the lenses to be exchanged in order to optimize their use in different lighting conditions are known in particular as sunglasses or protective glasses for skiing, cycling or motorsport, in order to enable the replacement of glasses under changed lighting conditions or in the event of damage . Various technical solutions have been proposed to detachably attach interchangeable glasses to the frame at any time. For the most part, however, previously resulting constructions have clearly visible clamping devices, which largely determine the design and allow only a few stylistic variations. The glasses are held by hooks, pawls, operating levers or similar measures on or within the frame. For example, EP-0046785 A describes an eyeglass frame with multiple lens hooks which are connected to the lens ring and a latch arm which is pivotably mounted in the temple bracket part, or a latch slide which can be displaced in the temple bracket against a spring and which is in a first position in which it holds the lens holds together with the lens hook on the lens ring, is movable into a second position in which it releases the lens for lateral displacement movement. Analogously to the otherwise known constructions with arranged lens hooks, such as US4,176,921 A, in which a pivotable fastening hook hinged to the nasal bridge serves to fix or release the glasses, the construction has the disadvantage of including a clamping device which is different from the The front of the glasses frame is clearly visible, whereby the stylistic freedom of movement is limited to the design-related shape. Corresponding functional engagement surfaces have so far been provided for actuating the clamping devices in order to carry out the desired procedure.

The present invention includes a further consideration for the definition of the problem area: since when glasses are purchased, the glasses represent a high cost share in accordance with their design, in particular the tint or the often complex optical grinding, it is usually costly for the user. to buy several glasses of different designs. From an economic point of view, however, there is a need to be able to have eyeglass frames that are more adaptable than the clothing or the purpose of use, in terms of effort and expense. Thus, it would be desirable if a fundamentally constant pair of glasses were each opposed by the largest possible number of stylistically different glasses frames that were compatible with them and which could be exchanged for the pair of glasses. For this purpose, clamping devices are necessary which do not restrict the stylistic freedom of movement in the shaping by arranging actuating levers or hooks provided in addition to the usual structural components such as frame, nose bridge, temple bracket approaches and temple bracket.

The glasses on the inner groove-bearing frame have so far been usually closed laterally on two-part locking blocks in the temple temple area by means of screws. Conventional frame frames and temples attached to them are soldered, glued or made in one piece, depending on the materials used, whereby the temple frames can be pivoted via a joint, depending on the design, with the temple frame approaches or directly connected to the frame. The difference between the present invention and the aforementioned conventional constructions is the change in design, as well as the arrangement and operation of the clamping devices in favor of further stylistic freedom of movement in the shape of the eyeglass frame.

One of the objects of the present invention is to provide new eyeglass frames of a type which enables the frame frames to be replaced easily in relation to a pair of glasses which in principle remains the same and avoids the disadvantages of the known eyeglass frames mentioned above.

A further object of the present invention is, despite the arrangement of a clamping device, not to restrict the stylistic freedom of movement in the shaping by arranging actuating levers or hooks provided in addition to the usual structural components, such as frame frames, nose bridges, temple temples and temple temples, and at the same time advantages in terms of production and application technology compared to conventional eyeglass frames with tool-free clamping devices.

The most important task of the invention in favor of production, design and application advantages is the idea of bringing about the fixing or solution of the mounting condition by directly manipulating the adjustable temple temple approaches that are present in a spectacle frame, which can be operated without tools, without additional stylistic evidence - 3 AT 004100 Ul freedom of movement in the design restricting, visible in the assembly position operating levers, hooks or the like.

To solve these tasks, the features mentioned in the characterizing part of claim 1 are provided in an eyeglass frame of the type mentioned. The change in the construction of the eyeglass frame, as it is thereby proposed, is based, compared to conventional designs, essentially in the arrangement and functional operation of the clamping device, by means of which the assembly state is determined or released. When grasping the glasses, the temple temple lugs, which are present per se in a spectacle frame, represent the attack surface to be manipulated in order to fix or solve the mounting position and thus take on direct actuating function of the clamping devices in the direction of movement of the intended relative adjustability of adjacent components. The actuation of the clamping device is also easy to handle in the case of stylistically small temple bracket approaches by moving the temple bracket which is disordered in its extension in the direction of adjustment.

The advantages of integrating the clamping devices into the temple bracket approaches are the avoidance of clamping devices visible in the assembly position. In this way, a clamping device with considerable design advantages over known constructions is created. Since the clamping devices on the eyeglass frames are structurally concealed in the mounting position by the temple temple lugs, which are already present, and the design does not influence the design, the freedom of design is unrestricted in contrast to conventional designs.

As a desirable effect, it is possible for the user through this structural measure to acquire several glasses frames with different designs and / or materials, each with a standardized internal cutout, for optional use, with glasses ground in when purchasing the first glasses of the type according to the invention, without this implying Change system is structurally recognizable. This makes the replacement of glasses frames with a constant pair of glasses both stylistically and economically attractive. For example, a number of glasses frames with different designs and / or materials can be equipped with the same pair of glasses, depending on the intended use or the fashionable coordination with the clothing. As we also found, this construction increases the stability and resistance of the frame to torsion or impact loads.

With a preferred arrangement of a known locking resistor, for example a spring, the first closure part is pushed into the assembly position under its action and can be moved into a releasing position 4 AT 004100 Ul against its action.

In one embodiment of the same category, the features mentioned in the characterizing part of claim 2 are provided. The advantages of this construction lie in the small overall width as well as in the possibility of partially rimless mounting of the glasses by means of segmental mounting frames without arrangement of tension threads, visible screws, hooks, levers or the like. In this way, the same pair of glasses can be easily gripped in a fully bordered as well as in a partially rimless spectacle frame.

To increase the stability of the mounting state of the clamping device, the features are provided according to claim 3. The first closure parts, which correspond to the closure counterparts, each of which is divided into at least two molded parts, fix the molded parts of the closure counterparts arranged at the ends of the socket frames with mutual engagement or engagement.

It proves to be favorable for the stability of the assembly if the features according to claim 4 are additionally provided. With these features is achieved by interlocking the first closure parts and corresponding closure counterparts with advantage 1 small width of the clamping devices.

To simplify the manufacture, the features according to claims 5 and 6 are provided. On the basis of wear-resistant materials, both temple bracket approaches and frame frames with out or. molded first fastener parts or corresponding fastener counterparts are each produced in one piece in predetermined shapes without using separately produced fastener parts as fittings in additional work steps. These structural measures also serve to reduce the overall width of the clamping device.

Advantageously, according to claim 7, the devices for locking the mounting position are each formed from locking projection and locking recess, which are each molded or molded on the first locking part or on the locking counterpart.

The features of claims 8, 9 and 10 represent the constructive embodiments for the adjustable mounting of the temple bracket approaches according to the invention. The features according to claim 8 result in a construction of the clamping devices that is easy to handle from the course of movement of the adjustment. The rotary movement is performed when operating the temple bracket approaches either through the assembly state leading engagement in the mutually opposite at the parting line of the eyeglass frame molded parts of the locking counterparts or by articulation at a fixed point at each end of the frame. The features according to claim 9 result in a guidance of the adjustment movement by a pivot axis. The assembly state is achieved by engaging the first locking parts arranged on the temple bracket lugs in the locking counterparts respectively arranged on at least one end of the mounting frame or by externally reaching around the ends of the mounting frame each arranged at the opposite ends, each divided into two shape parts Locking counterparts made.

A clamping device that is particularly simple in terms of production technology and application results when, according to a further embodiment, the features according to claims 10 and / or 17 are provided.

If the structural features according to claim 11 are provided with regard to the rotatable mounting of the temple bracket approaches, the clamping devices according to the invention have a dual function as a means for determining the mounting state of the severed frame, as well as a composite device between the components adjacent to the continuous material joint Fas solution frame and temple bracket attachment. Depending on the design, the bayonet lock can be fixed or released by a rotary movement or by a sliding movement. As a result, the frame and the temple brackets with the temple brackets attached to them can be exchanged for any design with system-compatible clamping devices in a simple manner without the aid of tools, which means that spectacle frames are not only extremely economically produced from modular components, but also in accordance with the modular system can be individually varied by the user in accordance with the available number of mutually design-compatible, structurally compatible modular components. As we found out, this structural measure can significantly reduce the production costs through the independent production of individual modular interchangeable components with a larger raw material evaluation.

The embodiment according to claim 12 represents a structurally simple and easy-to-use closure of the severed frame frame, the assembly state being locked by a voltage resistor.

If the features according to claim 13 are additionally provided, depending on the structural arrangement in the side area or on the back of the frame, there is the advantageous possibility of lateral width variation of the spectacle frame or of varying the overall length between the frame and the ends of the temple arms. This arrangement has the advantage of being easy to adapt to individual wearers or functional purposes, for example as sports glasses that are only temporarily tight on the temples.

According to a further embodiment, the features of claim 14 are provided. The glasses are gripped by compressing the locking block parts with the hollow cylinder recess in the expansion plane and then rotating the same until the recess comes to lie in a plane different from the expansion plane 6 AT 004 100 Ul. This effect can be achieved both by a circular cylinder with a circular cross section and by a segmental, approximately semicircular hollow cylinder. The hollow cylinder can be mounted in such a way that it rotates around the locking block halves when it is rotated, or an axial bearing is provided at a fixed location on one of the ends of the severed frame.

A simple device for locking the mounting state of the temple bracket approaches is also given if, according to a further embodiment, the features according to claim 15 are provided.

With the aid of the features according to claim 16, the locking block parts formed on the mounting frame are fixed as a result of being clamped by the legs of a locking counterpart with a U-shaped cross section, which are arranged at a distance from one another parallel to the parting plane of the mounting frame.

In the following, reference is made to the drawings:

The spectacle frames shown each consist of two frame frames -1- which can be expanded along a dividing joint -7- for mounting the glasses -4-, which support the glasses -4- at their edges -44- in the inner groove -5- and via a nose bridge - 24-are positioned in a predetermined position with respect to one another, and optionally made from nose pads -22-, and from at least one end -8.8A- of the frame 1- adjoining the parting line -7- of the frame bracket -1- arranged temple temples -2- and off via a joint -6- to the temple temple on these temple temples -3-. There is an essentially continuous material joint -9- between the frame frame -1- and the temple bracket attachments -2-. The clamping devices are designed such that the first locking parts -20- are each provided on the position-adjustable temple bracket lugs -2- and the corresponding locking counterparts -15- are each provided on at least one of the ends -8- of the frame 1 -1. In the contact area of the first locking part -20- and locking counterpart -15-resp. the two molded parts -15A.15B- each have a device -12- for locking the mounting position -I-. In each of the exemplary embodiments, the temple bracket lugs -2- are completely adjustable from the mounting position -I- to a second position -II-, in which the glasses -4- can be removed from the frame frame -l-. When the mounting position -I- is loosened, the glasses - -4- are used for most of the materials used in the manufacture of glasses to create a natural expansion of the frames -1- due to their inherent tension.

The representations in FIGS. 1 to 4 illustrate the four schematic arrangement forms of temple temple inserts -2- designed according to the invention and frame 1 -1. In FIG. 1 there is the continuous material joint -9- between the ends -8.8A- of the frame frame -1- completely surrounding the glass -4- and the temple bracket attachment -2- which laterally widens the spectacle frame. In contrast to FIG. 1, in the arrangement according to FIG. 3 there is the continuous material joint -9- between frame frame -1- and the temple bracket attachment -2- positioned on its rear and in the arrangement according to FIG. 4 between frame frame -1- and on the front of the temple bracket attachment -2-. As shown in FIG. 3, the ends -8.8A- of the mounting frame at the parting line -7- can be designed in the form of groove -53- and tongue -54- in favor of exact alignment. In the arrangement form gladly. FIG. 2 are following the same inventive idea in the case of segmentally designed frame frames -1- on the 9 AT 004 100 Ul

Inner groove -5- provided with this in each case aligned and adjustable relative to this temple bracket lugs -2-, which form an integrated part of the frame frame -1-. The segmental design can also be chosen such that the frame frames -1- are each designed without the lower segment -43- for partial rimless installation. Corresponding to the segmental design, the first closure part -20- is provided on at least one end of the temple bracket attachment -2- and the corresponding closure counterpart -15- is provided on the at least one adjacent end -8- of the frame frame -1.

The exact structural measures are identified in detail in the following exemplary embodiments for the four named arrangement forms. Exemplary embodiments of the schematic arrangement form according to FIG. 1 are the FIGS. 5 to 11, 13 to 21B and 26 to 31A, of the schematic arrangement form according to FIG. 2 the FIGS. 22 to 22C and of the schematic arrangement form according to FIG. 12A and 23 to 25. Herein the exemplary embodiments according to FIGS. 5 to 17B illustrate the adjustability of the temple bracket attachments by a rotary movement, the exemplary embodiments according to FIGS. 18 to 22A their adjustability by pivoting and FIGS. 23 to 31A their adjustability by means of a displacing movement. 5 to 9A, 13, 13A, 15, 15A, 18, 20 to 21B, 28 and 28A, the temple bracket extensions -2- are each in one piece with the first closure part -20-, and in FIGS. 8 to 9A, 13 to 19, 21 to 22C, 26 to 26B, 28 and 28A, the ends -8.8A- of the frame frame -1- are each formed in one piece with the locking counterparts -15-. The exemplary embodiments according to FIGS. 5 to 7, 10 to 12A, 23 to 28A and 30 to 31A each allow a completely detachable connection between the frame frame -1- and temple bracket attachments -2-. It goes without saying that the adjustment movements of the temple bracket approaches -2- can also be carried out easily by dog-style guidance of the temple bracket -3-. The eyeglass frames -90- are interchangeable according to the task according to the invention in relation to the glasses -4- against those with frame frames -1- having the same interior cutouts of predetermined constant relative position to one another with any other stylistic shape, without the frame frame components -1-, nose bridge -24- , Sleeper temple attachments -2-and sleeper brackets -3- must also arrange actuators which determine the design. Any materials, for example acetate, aluminum or other metals can be used to manufacture the spectacle frame. At the same time, the arrangement according to the invention is selected such that no shear stress is exerted on the frame frame -1- or glasses -4- during the manufacture or solution of the mounting position -I-. The manipulation of the clamping device is carried out with one hand, while the other holds the frame frame -1- pressed against the expansion plane with the glass -4- inserted into the inner groove -5-. When the clamping device is released, it can be released, the frame 10 AT 004100 Ul frame -1- released by loosening the finger pressure in the expansion plane, and the glass -4- can be removed from the inner groove -5-.

For the rotatable mounting of the temple bracket attachment -2-, in the exemplary embodiment according to FIG. 5, the first closure part -20- is formed in one piece with the temple bracket attachment -2- in the form of a hollow cylinder, on the inside of which in the region of the opening -62- facing the frame frame -1- two mutually opposite, medially projecting engagement blocks -42- are provided with essentially triangular ledge sides. The corresponding locking counterpart -15-, which is divided into two molded parts -15A, 15B- at the ends -8.8A- of the frame frame -1-, is cylindrical in shape with respect to the first locking part -20- in a positive-negative profile and has two on the outside opposite channel-shaped guides -49- with an angled course. The engagement blocks -42- engage in the channel-shaped guides -49- with a rotary movement of about 90 degrees clockwise, whereby the temple bracket attachment -2- is first pulled to the fitting frame -1- and when the engagement blocks -42-are in a constricted position within the channel-shaped guides -49- is locked.

In contrast to FIG. 5, in the exemplary embodiment according to FIG. 6, in the region of the opening -62- of the first closure part -20- directed towards the mounting frame -1-, engagement tabs -55- are provided in the medial direction, which engage in rotation on the outside of the corresponding one Grasp the molded parts -15A.15B- of the first locking part -15- shaped raised thread rails -50-. To determine the assembly state, the temple bracket attachment -2- until the stop of the first closure part -20- on the mounting frame -1- or for the stop of the molded parts -15A.15B- on an intended lateral cover plate -46- of the first closure part -20 - turned.

In a variant, two engagement blocks -42- are each formed on the inside of the first closure part -20-, which is designed as a hollow cylinder, with rectangular end faces, which are formed after insertion into the two molded parts -15A.15B- of the closure counterpart -15- "L-shaped guides -49- with clockwise rotation engage in corresponding" U "-shaped guides -49A- up to stops -48-. The assembly state is locked by engagement of a latching projection -35- formed on the first closure part -20- medially in a latching recess -38- formed on the upper molded part -15A-.

In the exemplary embodiment according to FIGS. 8 to 8C, the locking counterpart -15- formed at the ends -8.8A- of the frame frame -1- is divided into two molded parts -15A, 15B-, the upper molded part -15A- being cylindrical and on its underside has a channel-shaped indentation which is semicircular in cross section and open towards the bottom, into which the lower molded part -15B-, which is round in cross section, engages to form the dividing joint -7-. The saddle 11- 004 100 Ul fenbügelansatz -2- is designed as the first locking part -20- in the form of a hollow cylinder -39- which is rotatably mounted on the fixed axis -45- around the molded parts -15A, which in the mounting position - I-, as shown in FIG. 8, has a lateral recess -29- in the cross section of the lower forrate part -15B-. To release the lower molded part -15B- in the expansion plane of the severed frame frame -1-, as shown in FIGS. 8B and 8C, the hollow cylinder -39- formed in this way is turned 90 degrees clockwise around the stationary axis -45- into the second Position -U- turned until the recess -29- coincides with the lower molding -15B-. The assembly position -I- is brought about in the opposite manner, whereby a locking is achieved by engagement of a locking projection -35- formed on the upper molded part -15A- in a locking recess -38- molded on the inside of the hollow cylinder -39-.

In contrast to FIGS. 8 to 8C, FIGS. 9 and 9A illustrate, in one embodiment variant, the formation of the first closure part -20- in the form of a segmental hollow cylinder -39- seen in cross section, the division joint -7- between the upper and lower molded part -15A .15B- runs essentially in the middle, but connects the centrally mounted stationary axis -45-to the upper molded part -15A-. In the assembly position -I-, as shown in FIG.9A, the molded parts -15A.15B- are fixed together, while after turning the temple bracket attachment -2- clockwise in the second position -II- the lower molded part -15B- in the expansion plane of the frame frame is released, as shown in FIG.

In the exemplary embodiment according to FIGS. 10 to 10C, the first locking part -20- and the corresponding locking counterpart -15- are designed as a bayonet lock, which is fixed or released by a rotary movement. Here, the locking counterpart -15-, which is arranged in mirror-like molded parts -15A.15B- along the dividing joint -7-at the ends -8.8A- of the mounting frame -1-, as illustrated most clearly in FIG. 10B, essentially has two opposite, each from a semicircular plate body -56- with up or down tongues -18- with locking device before jumps -35-. A divided rubber ring -19- arranged on the front of the plate bodies -56- is used to produce a flexible pressure component between the locking counterpart -15- and the first locking part -20-, which is designed in a positive-negative profile relative to the locking counterpart -15-, and on has its opening -62- to a cavity on the back, delimited by a cover plate -46- in the material height and in the diameter of the locking counterpart -15-, frame parts -27- projecting medially with locking recesses -38- corresponding to the locking projections -35-. In the mounting position -I-, as most clearly shown in FIG. 10A illustrates, the first closure part -20- fixes the tongues -18- of the molded parts -15A.15B-by means of the 12 AT 004 100 ul medially projecting frame parts -27- in such a way that the locking projections formed on them -35- with the locking recesses -38- of the first closure part -20- to cover. After a slight pressure on the temple temple attachment -2- normal to the forrate parts -15A.15B- and simultaneous rotation by 90 degrees counterclockwise, the tongues -18- come into a second position -II-, as most clearly illustrated in FIG. 10C. to lie in the region of the opening -62- which is designed to be negative to its shape, the first closure part -20- being able to be pulled off the molded parts -15A, 15B-. This construction results in a completely detachable connection between frame frame -1- and temple bracket ansen zen -2- and requires great freedom in design, since the shape of the glasses frame can be freely defined according to the available modular interchangeable, mutually compatible components of different designs. With the arrangement of second locking recesses -38- spaced apart from the locking recesses -38- on the projecting frame parts -27- of the first locking part -20-, the position of the temple clips -3- can be locked relative to the mounting frame -1- in two different angular positions .

In a variant of FIGS. 10 to IOC, the frame frame -1- is shown in FIG. III in a vertical plane along its narrow side, separated into two frame parts -1A, 1B. Analogously to the representations according to FIGS. 10 to 10C, the molded parts -15A, 15B- of the locking counterpart -15- are arranged rotated by 90 degrees. In an analogous construction to the exemplary embodiment described in FIGS. 10 to 10C, the arrangement of the temple bracket attachment -2- is provided on the rear of the frame frame -1- in FIGS. 12 and 12A.

In the exemplary embodiment according to FIGS. 13 and 13A, the temple bracket attachment -2- seen in cross section is profiled "L" -shaped and vertically about a fixed axis of rotation -45-, which is fixed at the upper end -8- of the frame frame -1- Level from the mounting position -I- to the second position -II- releasing the mounting position, rotatably mounted. The horizontal part of the temple bracket attachment -2- directed towards the mounting frame -1- forms one piece with the first locking part -20-, which in the mounting position -I- with the molded-in locking recess -38- into one at the lower end -8A - of the frame frame -1- molded channel-shaped groove -65- as a locking counterpart -15- engages with a molded locking projection -35-.
