Description

Lens combining structure of rimless glasses

Technical Field

The present invention relates to a lens connecting structure in rimless glasses. More particularly, the present invention relates to a lens connecting structure in rimless glasses, wherein a lens is coupled to a bracket and a bridge in more convenient, robust and safe manner without punching additional openings in the lens itself when assembling the lens, more safe and robust coupling force is improved according to a thickness and curvature of the lens, and a fixed portion of the lens is prevented from being deformed due to stress caused by the load depending on compression when the lens is coupled.

Background Art Generally, glasses are used for a case where a visual field is difficult due to weak eyesight or the eyesight has to be protected. A user wears glasses having an adequate degree (degree) depending on his or her eyesight. Usually, a pair of glasses have the rim of the glasses, a leg element, the bridge and a lens. In the above, the leg element is coupled to the rim of the glasses by the bracket so that the leg element is collapsibly coupled to the rim of the glasses, whereby the user can wear the glasses on his or her body (face).

In the past, the glasses were used as a means for protecting a wearer' s eyesight. However, the glasses have been used as a means such as accessory for expressing beauty. To this end, various shapes of glasses have been developed. Further, in order to minimize a total weight of the glasses and express more elegant personality, semi- rimless glasses or rimless glasses have been developed and used. Semi-rimless glasses have a structure in which a portion of a lens is supported by the rim of the glasses. Rimless glasses have a structure in which the lens is put on the bridge or is coupled by a bracket at its both sides, without the rim of the glasses for fixing the lens. Currently, semi-rimless glasses have advantages that they have a light weight and can express a variety of shapes compared to glasses in which the entire lens is fixed by the rim of the glasses. Rimless glasses do not need the rim of the glasses. Accordingly, the rimless glasses have a lightweight and a lens of various shapes, and can express a variety of shapes, compared to the semi-rimless glasses. Furthermore, rimless glasses can prevent the eyesight from being hidden by the rim of the glasses and allow a wearer' s face to naturally come into view without being hidden.

Therefore, it is a trend that rimless glasses, which are light and can express a variety of shapes and personality and beauty, are preferred than glasses having the lens coupled thereto by the rim of the glasses.

Meanwhile, in the conventional rimless glasses, openings are formed in the lens, which is then fixed by a connection screw. As such, the process of forming the openings in the lens is necessary. In this case, there are problems that the process is complicated and inconvenient. Furthermore, defective lens may occur frequently since the lens of a weak material (glass or plastic) can be easily broken or crack in the process of forming the openings in the lens. In addition, in fixing the lens through the punched openings, the lens is fastened by the connection screw in a state where the lens is directly brought into contact with the openings. In this case, the contact portion becomes weak and shock applied from the outside is directly applied to the lens. Accordingly, there is a problem that the weak portion easily cracks or is broken.

Furthermore, in the conventional rimless glasses, it is impossible to control the location of the lens when assembling the lens, i.e., to adjust the location of the lens in the top, bottom, left and right directions in order to match a user' s eyesight and the center of the degree in the lens. It is also difficult to set a correct location of the lens. For this reason, when assembling the lens using the connection screw, there is a problem that the assembly can be defective since the center is not exactly matched.

Meanwhile, rimless glasses as shown in FIG. 1 is mainly used as the aforementioned conventional rimless glasses. Such conventional rimless glasses 1 include an insertion element 111 formed at the front end of a bracket 110, a lens 120 coupled to the insertion element 111 by a connection screw 112, a leg element 130 collapsibly coupled to the rear end of the bracket 110 by means of a connection screw 112', and the bridge 140 having insertion elements 111 at its both ends, wherein the lens 120 is coupled by the bridge 140.

At this time, the lens 120 has coupling openings 122 formed therein. The coupling openings 122 have a predetermined diameter and are formed by individual opening formation processes. Nose support elements 141 are inwardly coupled to the bridge 140.

Therefore, some of both ends of the lens 120 are inserted into the respective insertion elements 111 formed in the connection member 110 and the bridge 140. The connection screw 112 passes through the coupling openings 122 formed in the lens 120 and is then mated with the bracket 110 and the bridge 140. The lens 120 is thus fixed/coupled by fastening the connection screw 112. In the conventional rimless glasses, however, the lens is fixed by the connection screw, which goes through the coupling openings formed by the opening formation process. It is necessarily required that the process for forming the coupling openings in the lens be performed. Therefore, the conventional rimless glasses have disadvantages that the process is complicated and inconvenient and the lens made from a relatively weak material (glass or plastic) is easily broken or cracks by small shock in the process of forming the openings in the lens. In addition, since the lens is fastened to the openings by the connection screw in a state where the lens is directly brought into contact with the openings, the contact portion becomes weak. If shock is applied to the glasses from the outside, it is directly applied to the lens without any buffering. Therefore, the conventional rimless glasses have a disadvantage that the punched coupling opening portion is easily broken or cracks.

Furthermore, the lens is fixed to the connection screw by means of the punched coupling openings. It is thus impossible to adjust the location of the lens, i.e., to adjust the location of the lens in the top, bottom, left and right directions in order to match a user' s eyesight and the center of the degree in the lens. It is also difficult to set a correct location of the lens. For this reason, there is a problem that the assembly may become defective since the center is not exactly matched when assembling the lens using the connection screw.

Best Mode for Carrying Out the Invention

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First Embodiment

As shown in FIG. 2 to FIG. 4, a connection structure of rimless glasses according to the present invention includes a bracket 10, an end part 11, a lens support piece 12, a screw shaft 13, a plurality of protrusions 14, a base plate 15 and a through-hole 16. In the above, the lens support piece 12 is formed on the inner surface of the end part 11. The screw shaft 13 having a predetermined depth is protruded inwardly to the end part 11. The plurality of the protrusions 14 are formed at the front end of the end part 11. The through-hole 16 passes through the center of the base plate 15 and a plurality of protrusions 14' are formed around the front end of one side of the base plate 15. In the above, a screw shaft 13 goes through the through-hole 16 and the base plate 15 is fastened by a nut 17. Thus, a lens 20 is compressed between the protrusions 14, 14' , which are formed corresponding to the end part 11 of the bracket 10 and the base plate 15. Furthermore, a guide hole 18 is formed at a predetermined location of the inner side of the end part 11 and an insertion pin 19 is formed at the other of both ends of the base plate 15. The insertion pin 19 is inserted into the guide hole 18.

FIG. 2 is a dismantled perspective view of a lens connecting structure in rimless glasses according to the first embodiment of the present invention and FIG. 3 is a cross-sectional view of rimless glasses according to the first embodiment of the present invention. One end of the lens 20 is coupled by the end part 11 of the bracket 10 and the base plate 15 in a compressed manner. Both lens 20 are connected by a bridge 40 having an end part 11' and a base plate 15' at its each end, which corresponds to the bracket 10.

In the above, the lens 20 connected by the bridge 40 are compressed by the protrusions 14' formed at the end part 11' and the base plate 15' as in the bracket 10. FIG. 5 is a partially expanded view of another lens connecting structure according to the first embodiment of the present invention. As shown in FIG. 5, the lens 20 are coupled by the bracket 10 in a compressed manner. At this time, the base plate 15 of the bracket 10 is not connected to the end part 11, but is independently inserted into the screw shaft 13 and is then fastened by the nut 17.

FIG. 6 is a partially expanded view of still another lens connecting according to the first embodiment of the present invention. A fixing shaft 22 where a female screw element 21 of a predetermined depth is formed at the end part 11 of the bracket 10 is protruded at a predetermined location of the inner side. The base plate 15 is fixed/coupled to the end part 11 by means of the connection screw 31, wherein a cylindrical element 24 through which the insertion opening 23 inserted into the fixing shaft 22 goes is formed in the base plate 15.

In the drawings, unexplained reference numeral 31' indicates a connection screw and 41 indicates a nose support element.

Hereinafter, how to assemble the connection structure of rimless glasses according to this embodiment will be described.

Referring to FIG. 2 to FIG. 4, it is assumed that the bracket 10 having the end part 11 and the base plate 15 which are each formed at locations corresponding to the plurality of the protrusions 14, 14' , the bridge 40 and a pair of the lens 20 are prepared. In this state, if it is desired to assembly rimless glasses 1, the bracket 10 is coupled to the outer end of each lens 20.

In the end part 11 of the bracket 10 and the base plate 15 coupled to the lens 20, the insertion pin 19 formed at the base plate 15 is inserted into the guide hole 18 formed in the end part 11. In a state where the screw shaft 13 penetrates the through-hole 16 and is then fastened by the nut 17, the leg element 30 is collapsibly coupled to the bracket 10 by means of an additional connection screw 31' .

As such, if the bracket 10 is coupled to one end of the lens 20, the lens 20 located between the end part 11 and the base plate 15 is compressed and firmly fixed by fastening the nut 17 to move the base plate 17 along the screw shaft 13. At this time, the lens 20 are solidly fixed/coupled in a state where the lens 20 are compressed by the end part 11 and the base plate 15. In particular, certain portions of the lens 20 are strongly compressed/fixed by the protrusions 14, 14' each formed in the end part 11 and the base plate 15.

Therefore, after the lens 20 is coupled by the bracket 10, the couple of rimless glasses 1 is completed by coupling the bridge 40 to the opposite side of the lens 20. The coupling of the lens 20 by the bridge 40 is same as the coupling of the lens 20 by the bracket 10 as described above. Thus, detailed description on it will be omitted for simplicity. At this time, the lens support piece 12 having a predetermined height is formed at the end of the screw shaft 13 in the bracket 10 in the longitudinal direction. This prevents the lens 20 fixed/coupled in a compressed state from being distorted or shaken.

As such, rimless glasses 1 are completed in which the lens 20 is coupled by the brackets 10 and the bridge 40 in a strong and convenient manner. Further, since the hole punching work for coupling the lens 20 is not required, it is possible to improve the strength and durability of the lens 20. Even if shock is applied to the bracket 10 or the bridge 40 from the outside, it is not directly applied to the lens 20, but is firstly buffered in the end part 11 and the base plate 15, thus protecting the lens 20 from the shock. In addition, in using rimless glasses 1, if it is desired to change the lens 20 depending on change in a user' s eyesight, anyone can easily change the lens because replacement of the lens 20 is convenient and easy.

Meanwhile, as another embodiment of rimless glasses 1 according to the first embodiment of the present invention, the base plate 15 of the bracket 10 for compressing and fixing the lens 20 is simplified, as shown in FIG. 5. It is thus possible to reduce materials and facilitate convenience and assembly. Further, as still another embodiment of the present invention, in coupling the lens 20 using the bracket 10, the fixing shaft 22 in which the female screw element 21 is formed is protruded toward the end part 11, and the cylindrical element 24 through which the insertion opening 23 into which the fixing shaft 22 is inserted is protruded from the base plate 15, whereby the base plate 15 is inserted into the end part 11, as shown in FIG. 6. At this time, the fixing shaft 22 is inserted into the insertion opening 23 formed in the cylindrical element 24 and is fixed by an additional connection screw 31. Therefore, the portion where the end part 11 and the base plate 15 are connected does not shows outwardly.

Accordingly, in an embodiment according to the lens connecting structure in rimless glasses as shown in FIG. 6, in a state where the fixing shaft 22 protruded toward the end part 11 is firstly inserted into the insertion opening 23 formed in the cylindrical element 24 of the base plate 15, the end part 11 and the base plate 15 are secondly coupled by the female screw element 21 and the connection screw 31. It is thus possible to make the couple of the lens 20 by the end part 11 and the base plate 15 more safely and firmly and to express elegant beauty of rimless glasses. Second Embodiment

FIG. 7 is a dismantled perspective view of a lens connecting structure in rimless glasses according to a second embodiment of the present invention, FIG. 8 is a partial cross-sectional view of a lens connecting structure in rimless glasses according to the second embodiment of the present invention and FIG. 9 is a cross-sectional view of rimless glasses according to the second embodiment of the present invention.

In rimless glasses according to the second embodiment of the present invention, a leg element 204 is collapsibly coupled by the bracket 202 and a lens L is compressed/fixed. Compression pieces 212 are formed on the front end of one side of an end part 210 for fixing the lens L, a screw shaft 214 having a predetermined length is formed upwardly at the center of the end point 210, and a fixing opening 216 is formed at the other end of the end part 210. A slot 222 into which the screw shaft 214 is inserted is formed at the center of the base plate 220, a protrusion 224 is downwardly protruded to form a bent 226 at the inner one side of the base plate 220, and a fixing protrusion 228 is downwardly protruded at the other end of the base plate 220. In the above, the compression pieces 212 formed on the end part 210 and the protrusion 224 protruded from the bent 226, in the base plate 220, are compressed/fixed in a state where the compression pieces 212 and the protrusion 224 are closely adhered to the lens L to be fixed. A nut 218 is connected to the screw shaft 214. Furthermore, the lens L has a different thickness depending on a difference in the degree. A thickness d at the central portion is thinner than a thickness D at the edge portion, i.e., a portion where the compression is made by the end part 210 and the base plate 220. FIG. 9 is a cross-sectional view of rimless glasses according to a second embodiment of the present invention.

As shown in FIG. 9, an end part 210 is integrally coupled to a bracket 202 to which a leg element 204 is collapsibly connected and a base plate 220 is inserted into a screw shaft 214, which is upwardly protruded at the end part 210, by means of a slot 222. In this process, a fixing protrusion 228 protruded from the base plate 220 is located at a fixing opening 216 of the end part 210.

FIG. 10 is a perspective view of another lens connecting structure in rimless glasses according to a second embodiment of the present invention.

As shown in FIG. 10, a lens L is compressed/fixed by an end part 210 and a base plate 220. At this time, a plurality of circular protrusions 211 are protruded from the end part 210. As a cushion member 213 of a thin film shape is adhered, a face contact is formed in a state where a portion brought into contact with the lens L is closely adhered by the cushion member 213. At the same time, the circular protrusions 211 are not directly brought into contact with the surface of the lens L but are compressed by indirect contact by the cushion member 213.

Referring to FIG. 7 to FIG. 9, the compression pieces 212 of a curved shape so that it has a predetermined curvature is formed at the front end of one side of the end part 210, the fixing opening 216 is formed at the other side of the end part 210, and the screw shaft 214 is upwardly protruded at the center of the end part 210. In this state, the end part is integrated with the bracket 202. If it is desired to fix the lens L using the base plate 220 through which the slot 222 inserted into the screw shaft 214 passes, the base plate 220 is inserted into the screw shaft 214 and is then roughly fastened by the nut 218. In this process, simultaneously when the base plate 220 is inserted into the screw shaft 214, the fixing protrusion 228 protruded from the base plate 220 is inserted into the fixing opening 216 coupled to the end part 210.

In this state, if the lens L having different thickness D and d are located between the end part 210 and the base plate 220 and are then fastened by the nut 218, the lens L are compressed and fixed by the compression pieces 212 formed on the end part 210 and the protrusion 224 protruded from the bent 226 of the base plate 220. At this time, as the portion of the compression pieces 212 formed on the end part 210, which is brought into contact with the lens L, is bent to have a predetermined curvature, it is closely adhered to the lens to form a face contact.

In addition, a portion of the base plate 220 in which the bent 226 is formed is generally downwardly curved so that it has the curvature. This is for preventing the portion from cracking and being broken due to the interference and contact with the edge portion, in the process of compressing/fixing the lens L since the lens L has a predetermined curvature and the thickness D at the edge portion is thicker than the thickness d at the central portion. In addition, after the base plate 220 is inserted into the screw shaft 214, the protrusion 224 formed at the bent 225 compresses/fixes the lens L by fastening of the nut 218. Thus, in the process of compressing/fixing the lens L, a compression force (load) a compression force (load) is concentratedly generated at that portion.

Therefore, since a compression force is concentratedly generated at the portion where the lens L is fixed starting from the screw shaft 214, a portion opposite to that portion has load to lifts upwardly the portion. In the present invention, as the fixing protrusion 228 downwardly protruded from the other end of the base plate 220 is inserted into the fixing opening 216 formed in the end part 210, the opposite portion is not upwardly lifted due to load depending on the compression of the base plate 220 to the lens L and the fixing protrusion 228 is inserted into the fixing opening 216.

As such, even if both portions starting from the screw shaft 214 are contrarily applied with load in the process of compressing/fixing the lens L using the base plate 220, the base plate 220 firmly compresses/fixes the lens L at a stable regular position. The fixing protrusion 228 serves as a prop with it inserted into the fixing opening 216. It is thus possible to prevent deformation, fluctuation and bending of the base plate 220 that may happen since some of the base plate 220 is lifted upwardly due to a compression force (load) depending on the compression of the lens L. Meanwhile, as shown in FIG. 10, if the plurality of the circular protrusions 211 are protruded on the end part 210 and the soft cushion member 213 is attached to the protrusions 211 in fixing the lens, a more wide surface is brought into contact with the lens L by means of the cushion member 213 in the process of fixing the lens L by the end part 210 and the base plate 220. Therefore, not only fixity is improved due to an increased frictional force, but also scar, etc. occurring on the surface of the lens L can be prevented by means of the cushion member 213 in compressing/fixing the lens L. Third Embodiment

According to a third embodiment of the present invention FIG. 11 shows the lens connecting structure of rimless glasses. As shown in FIG. 11, a leg element 304 is collapsibly coupled to an end part 310 by a bracket 302, protrusions 324' are formed at the front end of the inner side of the end part 310, a screw shaft 314 having a predetermined length is upwardly protruded at the center of the end part 310, and the end part 310 has a connection screw 332 to which the fixing body 320 is hinged. Further, a opening 322 into which the screw shaft 314 passes through a hinge mating opening 333, a protrusion 324 is downwardly protruded at the inner one end of the fixing body 320, a hinge mating opening 333 mated with the end part 310 is formed at the other end of the fixing body 320.

The end part 310 includes the screw shaft 314, which penetrates the slot 322 formed at the center of the fixing body 320 and the connection screw 332 is hingedly coupled to the hinge mating opening 333. Thus, the end part 310 drives the fixing body 320 hingedly. The fixing body 320 is lifted up, the lens L is inserted between the fixing body 320 and the end part 310, the fixing body 320 is then lowered again and the nut 318 fastens the fixing body 320. Furthermore, the protrusions 324, 324' for compressing/fixing the lens L are formed at the inner one ends of the end part 310 and the fixing body 320, thus preventing fluctuation of the lens.

Also, the bridge 340 that compresses/fixes a pair of the lens L having a predetermined degree and has a pair of a nose support elements 341 at the inner one end of the end part 310.

Therefore, after a portion of both ends of the lens L are inserted into the bracket 302 and the bridge 340 and are then compressed by the protrusions 324, 324' of the fixing body 320 and the end part 310, the bracket 302 and the bridge 340 are fastened by the nut 318 to fix the lens L.

Industrial Applicability

As described above, the present invention has effects that it can connect a lens in a convenient, safe and robust manner by using a bracket without punching a hole in the lens.

Consequently, there are effects in that a lens is prevented from cracking and being broken due to external shock and the life of the lens is extended in the long time.

Furthermore, a base plate fastened in a screw manner is curved to have an appropriate curvature according to a thickness and curvature depending on the degree of a lens. Therefore, the present invention has effects that it can improve durability against load due to fixed lens, completely prevent deformation such as bending, distortion or the like of the base plate, and minimize the failure rate. Further, protrusions and compression pieces are formed at a base plate and an end part, which directly contact a lens, wherein in the compression pieces, portions that are brought into contact with the lens have the same curvature. Therefore, the present invention has effects that it can improve robustness and stability depending on the compression/fixing of a lens and improve the use life of the lens.
