Description

Fixing structure of spectacle lens assembly and spectacles

The present invention relates to a fastening structure for fastening a spectacle lens assembly in which right and left independent spectacle lenses are integrated to a spectacle frame, and spectacles provided with the fastening structure.

In recent years, eyeglasses have been diversified against the background of changing consumer needs, and it has become common for consumers to use multiple glasses depending on the purpose and situation of use. Lenses have improved performance and become multifunctional. However, the design and structure of frames are diversifying.

Since eyeglasses require an appropriate combination of lens and frame based on individual information such as the user's eyesight, facial shape, application, and actual usage, and delicate processing, assembly and adjustment, It is common for eyeglasses stores to complete by processing, assembling, and adjusting one point at a time according to individual consumers' demands, and consumers change lenses and frames freely and change the combination. There was a problem that it was difficult.

For this, the right and left lenses, which often require different powers, are measured for each user, such as the center of the lens, the shape of the lens, the height of the lens, the distance between the center of the lens, and the distance between the lenses.・ If a spectacle lens assembly is processed and integrated based on the set specifications (hereinafter referred to as “lens specifications”), and is fixed to the frame, a plurality of spectacle lens assemblies are provided. Can be applied. Regarding the spectacles having such a configuration, in addition to the inventions described in Patent Documents 1 to 3, many spectacle lens assembly interchangeable spectacles have been proposed.
JP 2008-257148 A Utility Model Registration No. 3124380 JP-A-10-288760

However, although these prior arts can replace the spectacle lens or spectacle lens assembly corresponding to the frame of a specific shape and structure as detachable, both require a dedicated structure for both the lens and the frame. It is not applicable to frames of design and structure, and the combination of lenses and frames must be limited. Also, if the design and structure of the frame to which the lens is attached is different due to the structure of attaching the lens to the frame, the lens specifications are likely to fluctuate, and the visual acuity and appearance may be different when in use. Have Therefore, such spectacle lens assembly exchangeable spectacles are exclusively used as so-called “front spectacles” in which a second lens is attached to existing spectacles as an auxiliary, or “bounce-up spectacles” in which the lens is temporarily flipped up. Has been applied, but has not been able to solve the above problems.

The present invention has been made in view of such circumstances, and a spectacle lens assembly that is processed and integrated on the basis of lens specifications measured and set for each individual user into a frame of various designs. It is an object of the present invention to provide an eyeglass lens assembly fastening structure and eyeglasses that can be detachably fastened and allow a user to freely change a favorite frame.

In order to solve the above-mentioned problem, the fastening structure of the spectacle lens assembly according to claim 1 is a bridge in which the left and right lenses and the ends of the left and right lenses on the bridge side are locked to integrate both lenses. It is characterized by comprising a member and a joint member having one end detachably fitted to the bridge member and the other end fixed to the frame.

As described above, the spectacle lenses often have different powers on the left and right, and the left and right lenses must be held in an optimal positional relationship based on the lens specifications measured and set for each individual user. In normal rim type eyeglasses, the left and right lenses are cut so that the above lens specifications are realized when fitted to the rim according to the design and structure of the frame. That is basically difficult. In the case of rimless glasses, the tolerance is somewhat large, but basically the same. Therefore, in many cases, consumers are forced to purchase a lens and a frame for each pair of glasses.

In the present invention, the spectacle lens assembly in which the bridge-side ends of the left and right lenses are locked and integrated with each other is fixed to the frame via the joint member. By standardizing the size and structure of the bridge member, the processing range and arrangement of the left and right lenses are uniquely determined based on the frequency and lens specifications measured for each user, and integrated into an optimal state. A spectacle lens assembly can be produced.

Further, by standardizing the shape of the joint member and the nose part and the fixing structure of the other end to the frame, the spectacle lens assembly can be applied to a frame having a different design and structure. Thereby, various frames can be exchanged and used for one spectacle lens assembly.

Next, the invention described in claim 2 is the fastening structure of the spectacle lens assembly according to claim 1, wherein the bridge member is detachable on at least one of the upper surface, the lower surface, the front surface, and the rear surface. It has the locking hole which can be fitted to.

The configuration of the locking hole may be literally a “hole” shape, and is not particularly limited as long as it is another shape that can be attached to and detached from the joint member.

There are various types of spectacle frames, large, full rim type (where the rim holds the entire outer periphery of the lens), rimless type (where the rim is not partly or entirely), two-point type (where the rim is There is nothing, and one point on each of the left and right lenses is connected by a bridge, and the temple is also directly attached to the lens.

The spectacle lens assembly according to the present invention is assumed to be applied to the full rim type and the rimless type among the above. In the case of the full rim type, the spectacle lens assembly is fixed to the frame from the front or rear of the rim. In the case of the rimless type, the frame with the temple attached via a hinge is divided into an upper rim type that is located only above the lens and a lower rim type that is located only below the lens. The assembly is fastened to the frame from below, and is fastened to the lower rim type from above.

The other end side of the joint member according to the present invention is a full rim type in which the spectacle lens assembly is fastened to the front part of the bridge portion of the frame when the spectacle lens assembly is fixed from the front according to the form of the frame. When the spectacle lens is fixed from the rear surface, the spectacle lens is fixed rearward to the rear surface portion of the bridge portion of the frame. In the case of the upper rim type, it is fixed downward toward the lower surface portion of the bridge portion of the frame, and in the case of the lower rim type, it is fixed upward toward the upper surface portion of the bridge portion of the frame.

In addition, the fixing method to the frame on the other end side of the joint member is arbitrary including adhesion, screwing, fitting to a hole provided on the frame side, and integral molding with the frame. The position and angle at which the joint member should be fixed with respect to the frame is standardized by setting so that the bridge member of the spectacle lens assembly is held at a predetermined position and angle with respect to the frame regardless of the form of the frame. It is desirable.

Here, when the frame is a full rim frame and the spectacle lens assembly is fastened from the front, the bridge member's locking hole is on the rear surface. The upper rim type may be provided on the upper surface, and the lower rim type may be provided on the lower surface. When the locking holes are provided in all of the upper surface, the lower surface, the front surface, and the rear surface of the bridge member, the spectacle lens assembly can be applied to the frames of all the forms.

Also, since the joint member can be detachably fitted to the locking hole, the user can easily replace the frame and fasten the spectacle lens assembly. If the shape and size of the bridge member and the position and angle at which the joint member is fixed to the frame are standardized as described above, the fixed spectacle lens assembly regardless of the form of the frame is fixed to the frame. Since it is held at the position and angle, it is possible to prevent inconvenience and uncomfortable feeling due to changes in the appearance and the comfort when the frame is replaced. Note that the bridge member itself may be integrally molded as long as the joint member can be detachably locked, or may be configured by assembling a plurality of parts, and is particularly limited. Not.

Next, the invention described in claim 3 is the fastening structure of the eyeglass lens assembly according to claim 1 or 2, wherein the bridge member includes a front part having locking claws on both sides, respectively. It consists of rear parts, and the left and right lenses are locked and integrated by joining the front and rear parts by sandwiching the bridge side ends of the left and right lenses by the locking claws of both the front and rear parts .

The eyeglass lens assembly according to the present invention is basically formed by connecting left and right lenses with a bridge member in the same manner as two-point eyeglasses. However, since the two-point type eyeglasses have a structure in which the temple is directly attached to the lens, there is a problem that distortion of the whole eyeglasses including the temple directly affects the lens and changes the appearance and the wearing comfort. . On the other hand, in the present invention, since the spectacle lens assembly has a structure independent of the temple, the distortion does not directly affect the lens.

In the case of a structure in which screw holes are drilled in the left and right lenses, respectively, and connected to the bridge by screwing at only one point like two-point type glasses, the deformation of the bridge and the tension of the screwing will affect the position of the lens. There is a problem in that it affects the angle and changes the appearance and comfort. Also, when exchanging the lens, it is necessary to remove the screw once and then re-fasten it. Unless it is a specialist at a spectacle store or the like, it is difficult to dig a screw hole into the lens or to screw it properly. .

On the other hand, in the present invention, the bridge member is composed of a front part and a rear part each having a locking claw on both sides, and both the front and rear parts sandwiching the bridge side end portions of the left and right lenses by the locking claw of both the front and rear parts. By joining the parts, the left and right lenses are locked and integrated, so there is no need to make a screw hole in the lens itself, and there is no tension on the lens due to screwing. In addition, since the lens is sandwiched between the locking claws of both the front and rear parts and locked to the bridge member, not only can the deformation of the lens due to locking be minimized, but also the position and angle of the lens with respect to the frame are uniquely determined, Easily changes during use of the glasses. Furthermore, since a separate fastening member such as a screw or a screwing operation that requires specialized technology is not required, the user can change the lens by himself / herself as needed.

In addition, the structure of the latching claw that the bridge member has is not literally limited to the “claw-like” shape, and a part of both the front and rear parts joins the front and rear parts across the bridge side end of the lens. Accordingly, it is sufficient that the left and right lenses can be locked, and the locking claws of the front and rear parts do not necessarily have the same or contrasting shape.

Next, the invention described in claim 4 is the fastening structure of the spectacle lens assembly according to claim 3, wherein the front part and the rear part respectively have a front locking hole and a rear locking hole. The upper and lower locking holes are respectively formed on the upper and lower surfaces of the bridge member after the coupling by providing a gap between the opposite bridge side ends of the left and right lenses during the coupling to lock the left and right lenses. An opening is formed.

According to such a configuration, the coupled bridge member can be provided with the locking holes in all of the front surface, the rear surface, the upper surface, and the lower surface at the same time, so that the spectacle lens assembly can be applied to the frames of all the forms. . In addition, it is appropriate that all the locking holes formed in this case have the same size and shape including the internal structure.

Next, the invention described in claim 5 is a fastening structure of the spectacle lens assembly according to claim 4, wherein at least one of the front part and the rear part is a set of projections for joining the front and rear parts together. And a notch part into which the protrusion part fits at the bridge side end part of the left and right lenses.

As described above, since the lens is integrally locked with the bridge member in such a manner that the bridge side end portion is sandwiched between the locking claws of the front and rear parts, the movement of the lens in the front and rear direction is restricted. According to the configuration, since the notch portion of the lens is fitted into the protrusion portion of the bridge member, the movement of the lens in the vertical and horizontal directions is also restricted, and the lens is positioned at a predetermined position.

If the shape of the notch on the lens side and the cross-sectional shape and size of the protrusion on the bridge member side are standardized, the length of the notch, that is, the fitting position to the protrusion, can be determined for each lens. By setting according to the original, regardless of the size and shape of each lens, the position of the center of the lens provided with the notch portion of the same setting relative to the bridge member is uniquely determined. As a result, the user can freely use a plurality of lenses having cutout portions in which fitting positions to the protrusions are appropriately set in advance for one bridge member.

In addition, if the left and right lenses are each formed with a protrusion that protrudes toward the bridge member, and a notch is provided at the tip of the protrusion, the protrusion of the lens is sandwiched between the bridge members. Thus, the spectacle lens assembly can be configured. In such a configuration,
Since it can comprise so that the latching claw of a bridge member may not penetrate | invade in a lens main body, ie, a lens-shaped range, a user's visual field can be ensured more widely. Further, since the portion where the notch is fitted to the protrusion can be limited to the protruding portion between the engaging claws, the influence of the distortion on the lens body due to the engagement with the bridge member can be reduced.

A lens having such a protrusion is inexpensive and efficient by the eyeglass lens cutting method of the patented invention (Patent No. 5046333: eyeglass lens distortion prevention structure, eyeglass lens cutting method) possessed by the present inventor. Can be manufactured. According to the cutting method, a lens having an arc portion that forms an inverted arc-shaped curve portion having an arc center position on the outside of the spectacle lens is obtained. Therefore, the left and right lenses having protrusions are coupled to the bridge member. The integrated spectacle lens assembly can make the outer edge portions of the left and right lenses into continuous and integral curves, and can be excellent in design.

Next, the invention described in claim 6 is the fastening structure of the spectacle lens assembly according to claim 5, wherein at least one of the front and rear parts is connected to at least one side of the bridge side end of the left and right lenses. It is characterized by having a locking groove into which a stepped surface to be fitted and a locking claw of either of the front and rear parts are fitted.

According to the configuration of the present invention, for example, if a step surface is provided on the front surface of the bridge side end portion of the lens, a part or all of the thickness of the front part can be embedded in the bridge side end surface of the lens. It is possible to improve the integrity of the lens and the front part, and to improve the front appearance design of the spectacle lens assembly.

In addition, by fitting the locking claw into the locking groove, a part or all of the thickness of the locking claw itself can be embedded in the lens surface. In order to prevent the latching claw from shifting on the lens surface, the lens is more reliably coupled to the bridge member.

Next, the invention described in claim 7 is the fastening structure of the spectacle lens assembly according to claim 5 or 6, wherein the joint member has a set of elasticity in which a lock portion is provided at the tip. It has a substantially U shape with a pawl, and when fitted to the bridge member, the locking member of the engaging claw that penetrates into the locking hole engages with the side surface of the protruding portion, so that the bridge member stops on the joint member. It is characterized by being worn.

According to the configuration of the present invention, the engagement claw side becomes one end of the joint member, and the substantially U-shaped bottom is fixed to the frame with the other end. When fixing the spectacle lens assembly to the frame, the locking part provided at the tip of the engaging claw is inserted into the protruding part inside the bridge member by inserting the engaging claw side into the engaging hole of the bridge member. Engage. At the time of fastening, the lock portion is pressed against the side surface of the protruding portion by the elastic repulsion of the engaging claw itself, so that the bridge member and the joint member are securely engaged, and the fastening between the spectacle lens assembly and the frame is completed.

The strength of such engagement is that the spectacle lens assembly does not easily fall off the frame when the user moves or vibrates when using spectacles, and the user tries to separate the frame and spectacle lens assembly with both hands. In this case, the engagement is released so that the joint member can be removed from the locking hole. Further, as will be described later, when the nose part is mounted, the mounting portion enters between the engaging claws and fits therein, so that a double-locked state is established, so that the engagement becomes more reliable. Thus, the user can easily attach and detach the spectacle lens assembly to the frame without using any tools or the like.

Next, the invention described in claim 8 is a fastening structure of the spectacle lens assembly according to claim 4, wherein at least one set of locking claws of both the front and rear parts has a screw hole, The bridge side end of the left and right lenses are each provided with a through hole, and the lens is locked to the bridge member by engaging the screw through the through hole with at least one screw hole of both the front and rear parts. To do.

In the configuration of the present invention, through-holes are provided at the bridge side end portions of the left and right lenses in the same manner as the lenses used in the two-point glasses. Further, a screw hole is provided in each of the pair of locking claws of the front and rear parts, and the lens is directly fixed to the bridge member with the screw.

In such a configuration, screw holes may be provided in the locking claws of both the front and rear parts, and the lens may be screwed together with the lens sandwiched between the front and rear locking claws, or only the locking claws of either the front or rear parts A screw hole may be provided in the lens, and only the lens and the locking claw of the part may be screwed. *

As described above, when the lens is directly screwed to the bridge member, there is a possibility that the tension of the screwing may affect the position and angle of the lens, and the work of screwing work may occur. However, if the lens specifications are not as strict as the lenses for sunglasses, such as lenses for sunglasses with no power, and display / screen lenses for wearable computers, etc., or if the left and right lenses themselves do not need to be replaced separately For this purpose, it is appropriate to fix the lens more securely by screwing. Even in this case, the spectacle lens assembly itself can be easily attached to and detached from the frame by the joint member, and a plurality of frames can be exchanged for use.

Next, the invention described in claim 9 is the fastening structure of the spectacle lens assembly according to claim 8, wherein the bridge member is sandwiched between the front and rear parts and further between the front and rear parts. The middle part has a concave notch on the opposite inner side, and when the bridge member is joined, a vertical gap is provided between the middle parts so that the upper surface of the joined bridge member The lower surface is formed with openings serving as an upper locking hole and a lower locking hole, respectively.

In the configuration of the present invention, in order to form the upper locking hole and the lower locking hole, a pair of middle parts are provided between the front and rear parts with a vertical gap therebetween, On the lower surface, an opening surrounded by both front and rear parts and a set of middle parts is formed as a locking hole.

Moreover, since each middle part has a concave notch on the inner side, it corresponds to a locking hole provided in either or both of the front and rear parts inside the bridge member in a state of being sandwiched and joined between the front and rear parts. A horizontal gap is formed.

According to such a configuration of the bridge member, the substantially U-shaped joint member according to the invention of claim 7 is fitted from any of the upper side, the lower side, the front side, and the rear side so that the spectacle lens assembly is attached to the eyeglass lens assembly. Can be fixed to a fixed frame. Specifically, the locking part at the tip of the engaging claw of the joint member inserted into the locking hole engages with the cross section of the concave notch of both middle parts inside the bridge member, and the eyeglass lens assembly and the frame are stopped. The wear is complete.

Finally, the invention described in claim 10 is an eyeglass provided with any one of the fastening structures of the eyeglass lens assembly according to claims 1 to 10. The frame can be applied to both the rimless type of the upper rim type where the frame is located at the upper part of the lens and the lower rim type where the frame is located at the lower part, as well as the full rim type. The present invention can be applied to eyeglasses that can be fixed from either the front or rear direction.

The fastening structure of the spectacle lens assembly according to the present invention described above provides a spectacle lens assembly and a nose pad as an independent set for each user, in contrast to the conventional spectacle configuration in which a lens is incorporated into a frame. Since this is characterized in that it can be fixed to a plurality of frames having joint members, the following technical effects can be obtained.

(1) A spectacle lens assembly manufactured based on lens specifications determined by measurement data of individual users is fixed to a frame of any form in which the joint member according to the present invention is fixed at a predetermined position and angle. Can be used. Therefore, as long as the user possesses at least one eyeglass lens assembly, the user can freely exchange and combine a wide variety of frames. Therefore, the user has the effect of greatly expanding the degree of freedom in selecting eyeglass designs. In addition, since only the frame needs to be replaced, the cost burden on the user can be greatly reduced compared to purchasing a plurality of glasses. Conversely, if a plurality of spectacle lens assemblies with lenses according to the application and actual use are possessed, they can be used after being exchanged for the same frame.

(2) Conventionally, every time a lens breaks or the frequency progresses, the user goes to a spectacle store or the like to place an order for an eye replacement lens or leave the spectacles themselves, and then go to the lens cutting and frame After wearing, it was necessary to go to an eyeglass store again for adjustment. However, if the fastening structure of the spectacle lens assembly according to claims 1 to 7 is applied, the user obtains the same lens obtained by cutting a predetermined notch or a locking groove based on his / her lens specifications. By doing so, you can easily attach and detach the lens yourself without the need for specialized techniques and tools, and precise adjustment is not necessary. In addition, if a pre-cut spare lens is prepared in advance, the lens can be replaced immediately and the use of the spectacles can be continued. Therefore, it is possible to greatly reduce the user's labor and time in exchanging eyeglass lenses, and to shorten the period when glasses cannot be used.

(3) There is an effect of greatly expanding the structural design of the frame and the design freedom. Conventionally, as long as the prescription lens is used, independent left and right lenses are used, so in the structure and design of the mass production frame, it is necessary to keep the lens specifications within the greatest common divisor range. The mounting position and mounting method, as well as the frame structure and design were constrained. However, if the fastening structure of the spectacle lens according to the present invention is applied, restrictions other than the predetermined standard regarding the position and angle at which the joint member is fixed are greatly reduced. Expand dramatically.

Hereinafter, modes for carrying out the present invention will be described with reference to the drawings.

(First embodiment)
1 and 2 are exploded views of each member showing the configuration of the spectacle lens assembly 1 according to the first embodiment of the present invention. FIG. 1 shows a state viewed from the front and FIG. 2 shows a state viewed from the rear. The spectacle lens assembly 1 is composed of left and right lenses 10R and 10L, a front part 20 and a rear part 30 constituting a bridge member 2, and a joint member 50. Wear and use.

FIG. 3 is an enlarged view showing the details of the bridge member 2, with the upper diagram viewed from the front and the lower diagram viewed from the rear. The bridge member 2 is composed of a front part 20 and a rear part 30, each of which has a pair of locking claws 22, 32 projecting on both sides of the part main bodies 21, 31, A substantially rectangular locking hole 23, 33 is provided at the center. Further, in the first embodiment, the part main body 21 of the front part 20 has a set of substantially cylindrical projections 25 protruding outside the locking hole 23 on the back surface thereof, and the part main body 31 of the rear part 30. Has a set of through-holes 34 on the outside of the locking holes 33 on the back surface thereof. Each projection 25 is provided with a blind tube screw hole 26. The front and rear parts 20 and 30 are joined by fitting a set of protrusions 25 into a set of through holes 34 and screwing a screw (not shown) through the through hole 34 from the rear part 30 side into a blind tube screw hole. However, in the coupled state, a predetermined interval is maintained between the front and rear parts 20 and 30 by the protrusion 25. The pair of protrusions 25 and the pair of through holes 34 may be provided in any of the front and rear parts 20 and 30 respectively. However, if the screw head is exposed on the front surface of the bridge member 2, the appearance from the outside is impaired. Therefore, the arrangement as shown in the figure is more desirable. A recess 24 for fixing the tip of a nose pad, which will be described later, is provided above the locking hole 23 on the back surface of the front part 20.

FIG. 4 is an enlarged view of the nose part 40. The nose part 40 is provided with a pair of pads 43 in a portion where the mounting part 42 protrudes from the upper part of the bowl-shaped nose part body 41 and hits the user's nose. In addition, a convex portion 44 that fits into the concave portion 24 when mounted on the bridge member 2 is provided in front of the distal end portion of the mounting portion 42, thereby preventing the nose part 40 from falling off.

FIG. 5 is an enlarged view of the joint member 50. The joint member 50 is substantially U-shaped with a pair of elastic engaging claws 51 provided with a lock portion 52 at the tip, and penetrates into any of the locking holes when fitted to the bridge member 2. When the locking portion 52 of the engaging claw 51 is engaged with the side surface of the protruding portion 25, it is fixed to the bridge member 2.

The joint member 50 is fixed to the frame 60 with the engagement claw side as one end and the substantially U-shaped bottom as the other end. When the spectacle lens assembly 1 is fixed to the frame 60, the engagement claw side is inserted into one of the locking holes of the bridge member 2, so that the end of the engagement claw 51 is formed inside the bridge member 2. The provided lock portion 52 engages with the protruding portion 25. In this state, the lock 52 is pressed against the side surface of the projection 25 by the elastic repulsion of the engagement claw 51 itself, so that the bridge member 2 and the joint member 50 are securely engaged, and the spectacle lens assembly 1 and the frame 60 are engaged. Fastening is complete. The interval between the pair of engaging claws 51 is matched with the width of the mounting portion 42 of the nose part 40, and when both the nose part 40 and the joint member 50 are mounted on the bridge member 2, the mounting portion 42 becomes a shape which fits into the substantially U-shaped inner surface of the joint member 50 exactly. As a result, the joint member 50 is in a double-locked state by the lock portion 52 of the engaging claw 51 and the mounting portion 42 of the nose part 40 and is securely fixed to the bridge member 2.

FIG. 6 is an enlarged view of the left lens 10L of the lens 10 according to the first embodiment as viewed from the front. A cutout 12 having a width slightly smaller than the cross-sectional diameter of the protrusion 25 is provided at the tip of the bridge-side end 11 of the lens 10L in the horizontal right direction, and corresponds to the cross-sectional shape of the protrusion 25 inside. A substantially circular fitting hole 13 is formed. When the lens 10 </ b> L is attached to the bridge member 2, the protrusion 25 enters the notch 12, and the circular cross section of the protrusion 25 is fitted into the fitting hole 13, so that the bridge-side end 11 is the bridge member 2. It is fixed at a predetermined position. When the material of the lens 10L is made of resin or the like having a certain elasticity, the protrusion 25 enters while slightly expanding the entrance of the notch 12, and when the notch is fitted into the fitting hole 13, the notch is caused by its elasticity. Return to its original state. Therefore, distortion due to fitting does not occur in the lens 10L, and the user can sense that the lens 10L is properly attached to the bridge member 2 with a moderate click feeling.

Further, the bridge-side end portion 11 is shaped to be slightly thinner than the surface of the lens 10L to form a stepped surface 14, and the surface of the lens 10L corresponds to the locking claw 22 toward the right in the extension line of the notch portion 12. A shaped locking groove 15 is provided. When the lens 10L is mounted, the projection 25 is fitted into the fitting hole 13, and at the same time, the side of the front part 20 abuts the step while covering the step surface 14, and the locking claw 22 is fitted into the locking groove 15. . In the first embodiment, the rear surface of the lens 10L is subjected to the same cutting process so that the rear part 30 and the locking claw 32 are fitted into the stepped surface 14 and the locking groove 15 on the back surface, respectively. 20 and 30 and the locking claws 22 and 32 are fixed to the bridge member 2 so as to be sandwiched from both the front and back surfaces.

At this time, the lens 10 </ b> L has the locking claws 22, 32 and the front and back in the left-right direction by fitting the protrusion 25 and the fitting hole 13, and the vertical direction by fitting the sides and the steps of the front and rear parts 20, 30. Since the positioning in the front-rear direction is achieved by the engagement of the locking groove 15, the lens 10 </ b> L mounted on the bridge member 2 is fixed without causing any deviation in the left-right direction, the up-down direction, and the front-rear direction. .

The lens 10R is omitted from the drawing because it forms a contrast with the lens 10L. In the first embodiment, the stepped surface 14 and the locking groove 15 on the lens 10 are cut on both surfaces of the lens. However, depending on the design conditions of the spectacle lens assembly, cutting is performed only on one side. Even in such a case, fixing that does not cause the above-described deviation is possible.

Here, the shape and arrangement of the bridge member 2 and the internal protrusions 25 and the locking claws 22 and 32 are standardized, and the notch 12 and the fitting hole 13, the step surface 14, and the locking groove 15 to the lens 10L. If the shape, size, and arrangement of the eyeglasses are digitized as specification data based on the user's lens specifications, the spectacle lens assembly 1 specification is uniquely determined, so even lens specification data measured and set in advance for each user If obtained, a spectacle lens assembly suitable for the user can be produced at any time without any measurement, regardless of whether it is a lens maker, a frame maker or a spectacle store. Even if one side of the lens is damaged, the user simply sends the specification data to the lens manufacturer and orders a new lens. It becomes possible to do.

7 to 11 are views showing an assembled state of the spectacle lens assembly 1 according to the first embodiment. FIGS. 7 and 8 are views of the spectacle lens assembly 1 as viewed from the rear. FIG. 7 and FIG. 8 show the state in which the rear part 30 is omitted, the nose part 40 is mounted from below, and the joint member 50 is mounted from above. 9 shows a state in which the rear part is mounted and the screw 34 is fastened to complete the spectacle lens assembly.

(Second embodiment)
24 to 28 are exploded views of each member showing the configuration of the spectacle lens assembly 3 according to the second embodiment of the present invention, and FIG. 24 is a perspective view showing a state seen from the front. , 26 is an enlarged view of the assembled state of the bridge member 4 as viewed from the rear, FIG. 27 is a plan view of the bridge member 4 as viewed from above, and FIG. 28 is a state where the spectacle lens assembly 3 according to the second embodiment is completed. It is the figure which looked at from the front. The spectacle lens assembly 3 includes left and right lenses 70 </ b> R and 70 </ b> L, a front part 80, a rear part 90, a set of middle parts 85, a nose part 40, and a joint member 50 that constitute the bridge member 4. The nose part 40 and the joint member 50 are the same as those used in the first embodiment.

The front part 80 has a pair of locking claws 83 projecting from both sides of the part main body 81, and each locking claw 83 has a blind tube screw hole 84 on the back surface of the front end portion. The rear part 90 has a pair of locking claws 93 on both sides of the part main body 91. Moreover, the part main bodies 81 and 91 are each provided with the substantially rectangular latching holes 82 and 92 in the center part. A set of middle parts 85 is sandwiched between both front and rear parts, and has a concave notch 86 on the opposite inner side, and its outer side surface has a shape corresponding to the outer edge shape of the bridge side end of each of the lenses 70R and 70L. And When the bridge member 4 is coupled, a vertical gap is provided between the middle parts 85 to form openings that serve as upper and lower locking holes on the upper and lower surfaces of the bridge member 4 after coupling. To do.

Each of the lenses 70R and 70L according to the second embodiment has a so-called lens shape, and is provided with a through hole 71 at the bridge side end portion and a notch portion 72 corresponding to the locking claw 93 on the back surface. . When attaching the lenses 70R and 70L to the bridge member 4, the blind tube screw hole 84 on the back surface of the locking claw 83 of the front part 80 and the through hole 71 of the lens are aligned with each other, and then the screw 94 is inserted into the through hole 71. And is fixed to the blind tube screw hole 84 by fixing it.

The rear part 90 is attached to the back surface of the front part 80 via a set of middle parts 85. At this time, the middle part 85 is sandwiched between the front and rear parts 80 and 90 so as to provide a vertical gap. Here, the thickness of each middle part 85 is matched with the thickness of the lens in the cutout portion 72 of each of the lenses 70R and 70L so that the back surface of each middle part 85 and the bottom portion of the cutout portion 72 are flush with each other. By making the thickness of the part 90 coincide with the depth of the notch portion 72, the back surfaces of the lens 70R, the rear part 90, and the lens 70L become an integrated continuous surface without unevenness, and can be excellent in design. In the second embodiment, the front part 80, the middle part 85, and the rear part 90 are bonded to each other.

Although not shown in the drawings, in the second embodiment, the locking claw 93 of the rear part has the same length as that of the locking claw 83 of the front part 80, and the front end of the locking claw 93 corresponds to the through hole 71 of the lens. If a screw hole (not shown) is provided and the notch 72 is shaped to fit the locking claw 93 including the through hole 71, the rear part 90, the lens 70 and the front part 80 are integrated with the screw 94. It can also be locked. Further, the arrangement of the front and rear parts 80 and 90 may be reversed in the front and rear together with the installation position of the notch 72 in the lens. However, if the screw head is exposed on the front surface of the bridge member 4, the external appearance is impaired. The arrangement as shown in the figure is more desirable.

FIG. 29 to FIG. 36 are diagrams illustrating a case where the spectacle lens assembly 3 according to the second embodiment is applied to upper rim type spectacles. 29 and 30, a pair of engaging claws 67 are installed with a stay 66 facing downward on a lower surface at a position corresponding to a bridge of a substantially U-shaped frame 64 in which a rim and a temple are integrated. The eyeglass lens assembly 3 is fixed to the frame 64 from below by the upper locking hole of the bridge member 4. FIG. 31 and FIG. 32 show an example using a frame 64 in which a pair of engaging claws 69 are installed rearward via a stay 68a by the same integral molding, and the spectacle lens assembly 3 is a bridge. It is fixed to the frame 64 from behind by a locking hole 82 provided in the front part 80 of the member 4. These examples are suitable not only for sunglasses but also for eyeglasses with a light and relatively simple structure, such as dedicated glasses for watching 3D movies and display / screen lenses for wearable computers.

By the way, depending on the type of the face of the user, particularly the positional relationship between the nose on which the nose pad is placed and the ear on which the temple is placed, the holding angle of the frame when wearing glasses is different. As a result, as shown in FIG. 33, the tilt angle of the lens with respect to the frame also changes, and the angle between the user's eye and the lens axis also changes, which may result in insufficient performance of the lens. With conventional glasses, except for the so-called “lens-up” glasses, the lens is fixed to the frame, and the tilt angle of the lens axis with respect to the eyes cannot be adjusted. In some cases, the user's face type is not suitable, and the frame options may be limited.

However, in the case of spectacles to which the present invention is applied, the spectacle lens assembly to which the lens is fixed is independent of the frame. Therefore, if an angle adjustment mechanism is provided in the attachment portion of the joint member to the frame, the spectacle lens assembly Since the tilt angle with respect to the entire frame can be changed, the angle of the lens axis with respect to the user's eyes can be optimally adjusted.

For example, if the joint member 53 having the attachment angle adjusting mechanism as shown in FIG. 34 is used for the upper rim type frames 64 and 65 shown in FIGS. 29 to 32, the inclination angle of the entire spectacle lens assembly with respect to the frame can be set. Can be changed. The joint member 53 is configured such that the attachment portion 54 to the frame is made of a material having plasticity and can be bent at an arbitrary angle. However, the tilt mechanism is configured such that the joint member 53 formed of two members is screwed or the like. The fixing may be performed at an arbitrary inclination angle, and the configuration is not particularly limited.

FIG. 35 is an exploded view of a member of an example of eyeglasses in which the joint member 53 having the above attachment angle adjusting mechanism is applied to the frame 65, and FIG. 36 is a completed view thereof. The frame 65 includes a stay 68b for fixing the joint member 53 to the bridge portion.

The specific structure of the fastening structure of the spectacle lens assembly according to the present invention and the embodiment of the spectacles to which the fastening structure is applied has been described in detail above, but the present invention is limited to the above embodiment. However, improvements or modifications can be made within the scope of the technical idea of the present invention, and they belong to the technical scope of the present invention.

According to the fastening structure of the spectacle lens assembly and the spectacles to which the fastening structure is applied according to the present invention, a wide variety of frames can be freely exchanged, and it is easy by itself without requiring specialized techniques and tools. In addition, it is possible to provide eyeglasses that can be attached and detached at a low cost without requiring precise adjustments, so that convenience for consumers and freedom of product selection can be expanded. In addition, since the structural design and design constraints of the frame can be reduced, the development of a more diverse and unique spectacle frame can be promoted. Furthermore, if the present invention becomes widespread, as will be described below, it is also possible to expect an effect that the distribution structure itself of the glasses and its components can be changed.

First, by strengthening collaboration among lens manufacturers, frame manufacturers, and eyeglass stores, it will be possible to expand user options and make product proposals that better reflect user needs. Glasses and their parts have characteristics as mass-produced products as well as characteristics as order-made products that are completed for each product according to the needs of users such as eyesight and facial characteristics, usage and actual usage conditions, etc. The collection of user information such as data and needs and the customization of products are mainly performed at a spectacle store. Medically correct corrected vision is often prescribed by an ophthalmologist, but in the end, the eyeglasses store decides the practical corrected vision that suits the actual condition and needs of each eyeglass.

Conventionally, with a few exceptions, lens manufacturers provide product variations within a certain standard that can be mass-produced exclusively for lens and frame manufacturers specially for frame development and manufacturing. Not only was it difficult to obtain information, but information sharing and development cooperation between lens manufacturers and frame manufacturers were not always sufficient. On the other hand, the spectacles store has user information, but the fact is that it must provide a combination according to the needs of the user among the mass-produced products of the manufacturers with the structural and design constraints described above. It was.

However, if the present invention is applied, the bridge member, the joint member, and the nose pad can be standardized, and the spectacle lens assembly is determined only by selecting the lens based on information for each individual user and determining the specifications of the cutting process. The specifications are also uniquely determined. If this makes it possible to standardize part specifications and share information such as spectacle specification data among lens manufacturers, frame makers, and spectacle stores, it will be possible to strengthen cooperation in the development and design of parts. By expanding the efficiency of high-mix low-volume production of parts, it can be expected to expand product options that reflect user needs and preferences.

Further, even a business operator who does not have the conventional know-how of eyeglass manufacturing can manufacture frames and eyeglasses if there is data such as the attachment positions of joint members based on standardized members and lens specifications. Eventually, not only lens makers, frame makers, and eyeglass stores, but also businesses in various industries can now provide finished eyeglasses regardless of the parts manufacturer. It is also possible to distribute mail order sales of finished products and parts and handmade eyeglass production kits that users can assemble themselves. As a result, it can be expected that the form of manufacturing and distribution of glasses can be changed to a form that can better reflect the needs of consumers.

Furthermore, if the present invention is applied, it becomes easy to standardize the main members of the spectacle lens assembly and the specifications of the lens cutting. As a result, consumers can purchase eyeglasses anywhere with minimal equipment and technicians that can measure vision and lens specifications.

For example, taking eyeglasses for fashion and sports as an example, we introduced eyesight measurement equipment to sports facilities such as apparel shops, beauty salons, and fitness clubs, and received lens specification measurement training from store staff and instructors. Let it be a technician. Then, in the store or facility, the eyesight measurement and lens specifications of the facility user are measured to create spectacle lens assembly specification data, and the user selects the desired frame from the frame sample. The specification data and the frame model number can be sent to the lens manufacturer or frame manufacturer to order eyeglasses, and the completed product can be handed over to the user at the store or facility. This makes it possible to propose glasses selection based on more practical and specific needs for consumer glasses, such as coordination with fashion and hair makeup, and the structure and design of glasses according to sports applications.

In addition, if a simple eyesight measurement space equipped with equipment and technicians is installed in a corner of a railway station, etc., spectacles delivered by a courier will be ordered by consumers who have stopped by the commuter. Even a method of purchasing eyeglasses, which has been impossible in the past, can be realized, such as using a lens assembly that is separately combined with a lens assembly that has been purchased separately through Internet shopping.

As described above, the present invention is not limited to merely solving the technical problems of the current glasses, but the industrial structure over the entire production and distribution of products that have high importance of customization while being mass-produced products called glasses. It has the potential to change significantly.
