Description
- This invention concerns a support for auxiliary lenses, suitable to be attached to a glasses frame equipped with main lenses, in order to temporally associate a pair of additional lenses, for example sun lenses, with said main lenses.
- The support according to the invention allows to assemble the auxiliary lenses securely and in such a manner as to allow a plurality of lenses, different in shape and size, to be coupled.
- Moreover, the support does not require complex equipment to make it, and allows a personalized production able to satisfy the clients' specific requirements in an extremely short time and at very limited cost.
- The state of the art includes various attachment and support devices used to temporally associate a pair of auxiliary lenses, for example sun lenses, to a glasses frame. These devices generally consist of a support, or trunk, which substantially defines an auxiliary frame, with a precise and defined shape, and comprising a plurality of metal hooks welded thereto and arranged to anchor the auxiliary frame to the main frame of the glasses.
- Producing a trunk of the type mentioned above entails preparing the equipment to shape and weld the metal wires, which requires a long time to prepare and work. Therefore, it is substantially impossible for producers of this accessory to satisfy clients' specific requirements in a short time and at reasonable cost. Moreover, with time, the metal hooks often do not have a sufficient grip, and repeated operations to assemble/dis-assemble them can progressively reduce the solidity of the hooks and cause them to bend or break.
- Even if the hooks are covered with a protective material they can in any case scratch or damage the glasses frame to which they are applied.
- Moreover, the welds with which the hooks are attached to the trunk, or with which the lenses are attached to the bridge, must be made with extreme care, so they are not visible and do not compromise the overall aesthetics of the glasses; this entails a further increase in the production costs.
- Other solutions provide auxiliary attachment elements, such as screws, rivets, or similar, or use glues to couple the hooks with the relative lenses. These solutions entail a considerable and often unsustainable increase in production costs and times for the supports.
- The present Applicant has devised and embodied this invention to overcome the shortcomings of the state of the art, and to obtain other advantages as will be shown hereafter.
- The invention is set forth and characterized in the main claim, while the dependent claims describe other innovative characteristics of the invention.
- The main purpose of the invention is to achieve a support for auxiliary lenses which does not require particular, complex and expensive production equipment, which will be easy and inexpensive to make and which can therefore be produced even in small, personalized quantities according to the clients' requests.
- A further purpose is to achieve a support for lenses which can be adapted to every type of frame, which will considerably reduce the risk of scratches or damage to the frame on which it is applied, and which will remain substantially unchanged with time, always ensuring high reliability and grip.
- The support for auxiliary lenses according to the invention comprises first attachment elements arranged on the periphery of each lens and suitable to anchor themselves to the glasses frame on which the lenses have to be applied.
- In a preferential embodiment, the support also comprises at least a connection bridge which, by means of second attachment elements attached to the respective lenses, unites the two auxiliary lenses.
- In one embodiment of the invention, the second attachment elements not only have the function of supporting the bridge and connecting it to the auxiliary lenses, but also of anchoring themselves to the glasses frame to couple said support for the auxiliary lenses to the glasses themselves.
- In a preferential embodiment, for every auxiliary lens there is one of said first attachment elements and one of said second attachment elements, distanced from each other along the edge of the lens; the second element, associated with the bridge, is arranged on the upper part of the lens and the first element is arranged on the lower part thereof. Advantageously, said two attachment elements are displaced towards the outer side of the relative lens.
- According to a variant, there are at least two of said first attachment elements for every lens, for example one in its lower part and one in its lateral or upper part.
- The first and second attachment elements are made of at least partly elastic plastic material.
- According to the invention, each of said first attachment elements consists of a segment with a section substantially shaped like an upside down U, able to attach itself to the respective auxiliary lens, and of a hook-type extension able to anchor itself elastically to the frame of the glasses on which the auxiliary lenses are applied.
- The upside down U segment, according to the invention, has elastic means able to be inserted and mechanically clamped inside a mating cavity made in the lens, ensuring that the auxiliary lenses are clamped securely, stably and enduringly, and preventing any risk of the segment accidentally coming out.
- The second attachment elements are suitable to be mounted and clamped to the respective ends of the connection bridge, which has its ends shaped in such a manner as to ensure an indissoluble connection, which also prevents any risk of the segment accidentally coming out.
- The connection bridge is advantageously made of plastic or metal material, preferably of wire, to ensure the desired elasticity and flexibility of the entire support and to allow the support to be easily coupled with the frame of the glasses, by exploiting this elasticity.
- When the second attachment elements also have the function of anchoring themselves to the glasses frame, the elasticity and flexibility of the connection bridge reinforces the coupling between the support for auxiliary lenses and the frame; in fact, said attachment elements are kept constantly under tension in their position, thus preventing the connection from loosening, or any possible accidental detachment.
- According to a variant, the connection bridge is made of semi-rigid metal material.
- The second attachment elements, when their only function is to attach the bridge, are substantially shaped like an upside down U, and in turn have elastic means suitable to be inserted and mechanically clamped into cavities made in the lenses for this purpose, in order to ensure an enduring attachment, substantially preventing any risk of the attachment means accidentally coming out.
- On the contrary, when the second attachment elements also function as a coupling between the support for auxiliary lenses and the glasses, they are substantially identical to the first attachment means.
- Thanks to the elastic clamping means, it is extremely quick and easy to assemble the first and second attachment means to the relative lenses, and no auxiliary equipment or working is required.
- In a variant, the attachment elements and the lenses, and the second attachment elements and the bridge, are coupled together definitively, by using adhesives.
- The support for auxiliary lenses according to the invention therefore does not provide auxiliary structures of the type with a metal trunk, such as those known in the state of the art, but provides to use universal elements, which can be prepared and assembled in a very short time and at a very limited cost, and then associated with lenses cut according to the required shape. Moreover, the support does not provide either complex assembly procedures, or auxiliary elements such as screws, rivets or similar; nor does it require holes or threads to couple and attach the attachment elements to the relative lenses.
- These characteristics and advantages of the invention will become obvious from the following description of some preferential forms of embodiment, given as a non-restrictive example, with reference to the attached drawings wherein:
- FIG. 1 is a front view of a support for auxiliary lenses according to the invention;
- FIG. 2 is a part view of the support shown in FIG. 1 associated with a pair of glasses;
- FIGS. 3a and 3 b show respectively, with a prospective view, the detail A and the detail B of FIG. 1, in the disassembled condition;
- FIGS. 4a-4 c show in section, from above, three embodiments of the detail of the coupling of the bridge and the second attachment elements;
- FIGS. 5a-5 c show in section, from the side, three embodiments of the detail of the coupling of the bridge and the second attachment elements;
- FIGS. 6a-6 g show six embodiments of the cavities made in the auxiliary lenses to couple with the respective attachment elements;
- FIG. 7 is a prospective view of the attachment elements according to the invention;
- FIGS. 8 and 9 show another embodiment of the invention, respectively from the front and with a prospective view.
- FIGS. 1 and 2 show a
support 10 forauxiliary lenses 11 of the type able to be temporally attached to a pair ofglasses 13 equipped withmain lenses 14 associated with aframe 20. Theauxiliary lenses 11 may be, for example, of the type for sun glasses, or special lenses, chromatic lenses, etc. - The
support 10 and theglasses 13 are coupled, in the embodiment shown in FIGS. 1 and 2, by means offirst attachment elements 16, arranged along the edge of therelative lens 11 and able to anchor themselves to saidframe 20. - In this case, the
support 10 has two of saidfirst attachment elements 16 for everylens 11, respectively one on the upper edge and one on the lateral edge of therelative lens 11. - The
first attachment elements 16 are made of at least partly elastic plastic material. - It is within the field and scope of the invention to provide three or more
first attachment elements 16 for everylens 11. - The
first attachment elements 16 comprise asegment 16 a shaped substantially like an upside down U defining acavity 18 able to be inserted and mechanically clamped, as will be seen hereafter, in amating cavity 17 made in therelative lens 11, and a substantiallyhorizontal extension 16 b terminally shaped like a hook. - The
extension 16 b is able to hook onto a relative segment of theframe 20 to clamp thesupport 10 to theglasses 13. - The
support 10 also comprises aconnection bridge 12 able to unite the twoauxiliary lenses 11; thebridge 12 is made preferentially of metal or plastic material at least partly elastic and flexible to facilitate the operations to attach/detach thesupport 10 to/from theglasses 13. - At the ends of the
bridge 12 respectivesecond attachment elements 15 are associated; these are shaped substantially like an upside down U and define acavity 21 able to cooperate with amating cavity 17 made in thelens 11. Thesecond attachment elements 15 are also made of at least partly elastic plastic material. - In the embodiment shown in FIGS. 8 and 9, the
second attachment elements 15 not only have the function of supporting the bridge and coupling it with theauxiliary lenses 11, but also as an attachment to theframe 20 of theglasses 13. In this case, thesecond attachment elements 15 are substantially identical in configuration to thefirst attachment elements 16. - The preferential embodiment of the invention provides in this case that, for every
auxiliary lens 11, thesupport 10 has asecond attachment element 15 with the double function of supporting thebridge 12 and as an anchorage to theframe 20, and afirst attachment element 16, distanced from thesecond attachment element 15 and arranged, for example, along the lower edge of thelens 11, towards the outside thereof. - Using the
second attachment elements 15 also as an anchorage to theframe 20 not only further reduces the number of pieces needed to produce thesupport 10, but also increases the stability of the coupling of thesupport 10 to theframe 20. In fact, the flexibility and elasticity of thebridge 12, exerting an action of elastic thrust against therespective attachment elements 15, keeps them under tension in their position, and hence prevents them from loosening and relaxing. - Inside the
respective cavities cavities 17 of thelenses 11; thecavities 17 in turn have a shaped conformation such as to ensure a stable anchorage which does not require further auxiliary elements, such as screws or suchlike. - In the solution shown in FIG. 7, the elastic attachment means22 consist of
fins 122 able to cooperate with the substantially T-shaped conformation of thecavity 17. By exploiting the elasticity of the material, thefins 22 are forced inside the T-shapedcavities 17, partly deforming and clamping themselves inside, in a stable manner so that they cannot accidentally come out. - On this point please see FIGS. 5a-5 c too.
- It is obvious that instead of the T shape, the
cavities 17 can be of other shapes, and some examples are shown in FIGS. 6a-6 g. - The
cavities 17 shown in FIG. 6a and FIG. 6g have ahole 17 b which allows a pin element or similar, which is included on theattachment element 15, to be inserted; in FIG. 6a thehole 17 b is round and is associated with a lead-in hollow, whereas in FIG. 6g the hole is square; thecavity 17 shown in FIG. 6b has a step-like enlargement at the bottom, whereas thecavity 17 shown in FIG. 6c has a gradual enlargement; thecavity 17 shown in FIG. 6d has lateral knurls, thecavity 17 shown in FIG. 6e has a circular enlargement at the bottom while thecavity 17 shown in FIG. 6f has an intermediate narrowing of section. - It is also obvious that for every different shape of the
cavities 17 the elastic means 22 will have a mating shape so that they can be inserted and mechanically clamped inside thereof. - To ensure a substantially indissoluble mechanical anchorage, suitable to prevent accidental detachment, the
bridge element 12 has its respective ends equipped with an anti-detachment shape cooperating with the respectivesecond attachment element 15. - Examples of these shapes are shown in FIGS. 4a-4 c.
- In FIG. 4a, the end of the
bridge 12 is substantially shaped like aT 19. - By exploiting the elastic deformability of the material which constitutes the
second attachment element 15, the T-shaped end of thebridge 12 can be inserted into a mating seating made for this purpose in the base thickness of saidelement 15; once it has been inserted, it is substantially impossible for the end to emerge, thanks to the T-shaped coupling. - In the embodiment shown in FIG. 4b, at its end the
bridge 12 hasknurls 23 made laterally, while in the embodiment shown in FIG. 4c it hasknurls 24 made on the upper part; the knurls are suitably oriented forwards so as to allow insertion but to mechanically prevent extraction once the coupling is achieved. - The shaping of the terminal segment of the
bridge 12 may be straight, as in FIG. 5b, or slightly curving downwards (FIG. 5a) or upwards (FIG. 5c), both for aesthetic reasons, for example to distance thebridge 12 from or bring it nearer to thelenses 11, and also to further reinforce the coupling between thebridge 12 and thesecond attachment elements 15. - To achieve the
support 10 it is therefore sufficient to cut theauxiliary lenses 11 to size, according to the desired shape, and then to mechanically apply thereto thefirst attachment elements 16 and thebridge 12 by means of the relativesecond attachment elements 15. - The
elements support 10 can be produced in a very short time, with limited costs and therefore also for extremely limited and personalized quantities. - Obviously, modifications and variants may be made to the invention, but these shall remain within the field and scope of the invention as defined by the attached claims.
