[Embodiment of the invention] 【Example】

 FIG. 1A is an enlarged partial cross-sectional view of an example of a lens mounting structure for eyeglasses according to the present invention when viewed from the flat surface side of the lens, and FIG. 1B is applied to FIG. FIG. 5 is an enlarged perspective view of the adjustment member to be used. FIG. 2 is an exploded enlarged sectional view of the lens mounting structure of the glasses shown in FIG. In the embodiment shown in FIGS. 1 and 2, a case where the lens mounting structure for eyeglasses according to the present invention is applied to the mounting of the lens of the frameless eyeglasses and the connecting member (Ji) on the temple side will be described. The eyeglass lens mounting structure 10 of the present embodiment includes a lens 12. The lens 12 has a through hole 14a near the end edge thereof, penetrating from one main surface of the lens 12 to the other main surface. In the present embodiment, the through hole 14a is formed, for example, in an elliptical shape when viewed from the front side of the lens 12. The through-hole 14 a is arranged in the lens 12 such that its major axis is substantially parallel to the length direction of the lens 12.

[0010] The lens 12 has a locking recess 14b formed at a position spaced apart from the through hole 14a by a predetermined distance. In the present embodiment, the locking recess 14b is formed by, for example, a cylindrical small hole provided near the through hole 14a. In this case, the distance from the center of the locking recess 14b to the peripheral edge of the through hole 14a of the lens 12 is formed to be, for example, about 1.5 mm. The locking recess 14b is provided to extend substantially vertically from the one main surface of the lens 12 to the other main surface by a predetermined depth. The depth of the locking concave portion 14b is substantially the same as the length of a locking convex portion 44 of the adjusting member 40 described later that is locked by the locking concave portion 14b.

The lens 12 is disposed on one principal surface side of the lens 12 and functions as a connecting member with the temple T. The lens 12 is disposed on the other principal surface side of the lens 12, and has a through hole of the lens 12. It is pinched and held by the fastener 18 inserted through 14a. Further, an adjusting member 40 is formed at the tip of the tongue 16 on the side opposite to the temple T side so that a locking projection 44 described later is appropriately locked to the locking recess 14 b of the lens 12. Is done.

[0010] The wisdom 16 is, for example, formed in a substantially L-shaped rod shape in plan view, and one end thereof is rotatably supported by a connecting end of the temple T by a hinge portion 20 (not shown) or the like. The tomography 16 includes, for example, an oval-shaped plate-shaped lens holding portion 22 connected to the other end. On one main surface side of the lens holding portion 22, an insertion columnar body 24 is formed substantially at the center thereof. The insertion columnar body 24 is formed on the side facing the lens 12 and the lens holding portion 22, and is formed at a predetermined interval from the other end of the chimney 16 to one end side. The insertion columnar body 24 is formed, for example, in an elliptical columnar shape at the bottom surface, and is formed perpendicular to the surface of the lens holding portion 22 facing the lens 12. The insertion columnar body 24 is provided to extend perpendicularly to the lens 12 surface side. The insertion columnar body 24 has a bottomed hole 26 extending in the axial direction, for example, having a circular cross section. On the inner peripheral surface of the bottomed hole 26 of the insertion columnar body 24, a screw portion 24a formed of, for example, a female screw, which functions as a fixing portion, is formed. The screw portion 24a is screwed with a screw portion 28a of a fixing portion 28 of the fastener 18, which will be described later, and is connected and fixed.

On the surface of the lens holding portion 22 facing the lens 12, the lens holding portion is in close contact with one main surface of the lens 12 around the insertion columnar body 24, and holds the lens 12 together with a fastener 18 described later. A surface 23 is formed. The lens holding surface 23 has lens contact surfaces 23a and 23b on one side and the other side of the insertion columnar body 24, respectively, when viewed in the long axis direction of the lens holding portion 22.

In the present embodiment, for example, the center of the through hole 14 a of the lens 12 is arranged at a position 3.0 mm from one end in the length direction of the lens 12. The length of the long axis of the lens holding portion 22 is formed to be about 5.0 mm, and in this case, the lengths of the lens contact surfaces 23a and 23b in the longitudinal direction are each formed to be about 1.0 mm. The length of the major axis of the insertion pillar 24 is 3.0 to 3.5 mm, the length of the minor axis is 1.8 to 2.3 mm, and the axial length is about 1.5 mm. I have. Since the size of the diameter of the through hole 14 a of the lens 12, that is, the length of the major axis and the minor axis is slightly longer than that of the insertion column 24, the insertion column 24 is connected to one side of the lens 12. When inserted into the through hole 14a from the main surface side, it is fitted almost exactly into the through hole 14a. Then, from the other main surface side of the lens 12, a fastener 18 is inserted into the through hole 14a, and is connected and fixed to the screw portion 24a of the insertion columnar body 24.

That is, the fastener 18 includes, for example, a columnar fixing portion 28. The fixing portion 28 has a screw portion 28a formed of a male screw portion on a peripheral surface thereof. At one end of the fixing portion 28 in the axial direction, for example, a hemispherical head 30 having a function as a fastening portion is integrally formed. The head 30 has, for example, a linear or cross-shaped groove 30a on its surface. In this embodiment, the outer diameter of the fixing portion 28 of the fastener 18 is formed to be, for example, about 1.2 to 1.4 mm. In this embodiment, a round screw with a cross hole is used as the fastener 18, but other small screws such as a round flat, a flat, a pan, a round head, and a flat head may be used as appropriate. You may.

Further, an adjusting member 40 is detachably formed at a tip end of the lens holding portion 22 of the wisdom 16. The adjusting member 40 particularly includes, for example, a bottomed cylindrical cap portion 42 as shown in FIG. The cap portion 42 has a locking projection 44 made of, for example, a cylindrical pin at an intermediate portion in the axial direction. The locking projection 44 is located near the bottom surface 43 in the axial direction of the cap 42 and extends outward from the peripheral wall surface of the cap 42. The locking projection 44 extends in a direction perpendicular to the axial direction of the cap 42. The diameter of the bottomed hole 42 a of the adjusting member 40 is formed to be substantially the same as or slightly larger than the diameter of the lens holding portion 22 of the chimney 16. Therefore, the adjusting member 40 can be removably fitted to the distal end portion of the lens holding portion 22 of the chi 16. The locking projection 44 is inserted into the locking concave portion 14b of the lens 12 and locked when the adjusting member 40 is fitted and attached to the distal end portion of the lens holding portion 22 of the lens 16. In the present embodiment, the axial length of the locking projection 44 of the adjustment member 40 and the depth of the locking recess 14b of the lens 12 are formed to be substantially the same. Since the diameter of the locking concave portion 14b is substantially the same as the diameter of the locking concave portion 14b, the locking convex portion 44 of the adjusting member 40 is fitted and locked in the locking concave portion 14b of the lens 12.

The fixing portion 28 of the fastener 18 is inserted into the bottomed hole 26 of the insertion column 24 from the other main surface of the lens 12 through the through hole 14 a of the lens 12. In the present embodiment, the fastener 18 is inserted through the insertion columnar member 24 in a state in which the close contact member 32 formed of, for example, a circular or elliptical seat is fitted around the fixing portion 28 of the fastener 18. . The contact member 32 is formed of a relatively flexible material. Then, the screw portion 28a of the fixing portion 28 of the fastener 18 and the screw portion 24a of the insertion columnar body 24 are screwed. Therefore, the insertion columnar body 24 and the fastener 18 are firmly connected and fixed. When a circular seat is used as the contact member 32, its diameter may be longer than the length of the long axis or the short axis of the through hole 14a of the lens 12. That is, since the contact member 32 is formed so that at least a part thereof is locked and adheres to the surface of the lens 12 at the periphery of the through hole 14a of the lens 12, the contact member 32 also has a function as a fastening portion of the fastener. Things.

In this case, since the through hole 14 a of the lens 12 and the insertion post 24 fitted into the through hole 14 a are formed in an elliptical shape, the rotation of the lens holding portion 22 is prevented, and the lens holding portion 22 Co-rotation with the fastener 18 can also be prevented. Further, by disposing the contact member 32 between the head 32 of the fastener 18 and the surface of the lens 12, the head 30 of the fastener 18 can be brought into close contact with the surface of the lens 12. In this case, since the contact member 32 is formed of a relatively flexible material, it is easy to adhere to the shape of the lens 12 surface. In addition, since the friction surface between the contact member 32 and the surface of the lens 12 becomes large, loosening of the fixing portion 28 of the fastener 18 is also prevented. Therefore, the lens 12 is sandwiched and held firmly by the lens holding portion 22 and the contact member 32 of the lens 16. At this time, the lens contact surfaces 23a and 23b of the lens holding portion 22 and the contact surface of the contact member 32 are in close contact with one main surface and the other main surface of the lens 12, respectively. Is firmly held in between.

In the eyeglass lens mounting structure of the embodiment shown in FIGS. 1 and 2, the adjusting member 40 having the locking convex portion 44 can be detachably attached to the tip of the lens holding portion 22 of the optical fiber 16. Therefore, for example, even if the formation position of the locking concave portion 14b of the lens 12 is shifted for some reason, it is possible to cope with it by appropriately adjusting the fitting length of the adjusting member 40 fitted into the lens holding portion 22 of the forehead 16. it can. In other words, in this embodiment, as in the conventional example of FIG. 10, for example, the distance between the insertion portion 3a of the chimney 3 and the pin 3b is changed according to the distance between the through hole 2a and the small hole 2b formed in the lens 2. Since the position is not determined, the insertion position of the adjusting member 40 into the tongue 16 is adjusted, so that the fitting columnar member 24 provided on the lens holding portion 22 of the tongue 16 and the locking projection of the adjusting member 40 are formed. The distance from the gap 44 can be changed as appropriate. Therefore, in the present embodiment, the mounting position of the lens 16 and the lens can be easily adjusted despite the simple structure.

In the embodiment shown in FIGS. 1 and 2, the lens 12 is not only held by the cooperative action of the insertion column 24 and the fastener 18, but also fitted into the locking recess 14 b of the lens 12. Since the lens 12 is also held by the locking convex portion 44 of the adjusting member 40 to be combined and locked, the contact surface between the lens 16 and the lens 12 is increased, and the lens 12 is firmly secured without rattling the lens 12. Can be held. In this embodiment, even if the lens contact surface 23b on the distal end side of the lens holding portion 22 is omitted, the lens 12 is held by the cooperation of the other lens contact surface 23a, the fastener 18, and the contact member 32. Although it is possible, it is more preferable to include two lens contact surfaces 23a and 23b as in this embodiment. Although not shown in FIGS. 1 and 2, the other lens (not shown) is also attached to the other lens (not shown) by the same eyeglass attachment structure 10.

FIG. 3 is an enlarged partial sectional view showing another example of the lens mounting structure for eyeglasses according to the present invention when viewed from the plane side of the lens. FIG. 4 is a lens mounting view of the eyeglasses shown in FIG. FIG. 3 is an exploded enlarged sectional view showing a main part of the structure. FIG. 5 is an illustrative view showing a principal part of the lens mounting structure of the glasses shown in FIGS. 3 and 4 and the like as viewed from the front side of the lens. FIG. 6 is a view showing the glasses shown in FIGS. FIG. 2 is a front view of a lens applied to the lens mounting structure of FIG. In this embodiment, the lens mounting structure of the glasses according to the present invention is applied to the mounting structure of the bridge B and the lens 12 as compared with the embodiment shown in FIGS. That is, the lens mounting structure of the glasses of the present embodiment includes the connecting portions 46 located at both ends of the bridge B. The connecting portion 46 is provided with a pad foot 48 having a pad (not shown). The lens holding portion 22 is connected to an end of the connecting portion 46 of the bridge B. As in the embodiment shown in FIGS. 1 and 2, an adjusting member 40 is detachably provided at the distal end of the lens holding section 22.

In the eyeglass lens mounting structure 10 shown in FIGS. 3 and 4, a step portion 50 is formed at a distance from the insertion columnar body 24, particularly near the tip of the lens holding portion 22. The step 50 is engaged with a part of the peripheral side wall of the cap 42 of the adjusting member 40 when the adjusting member 40 is attached to the tip of the lens holding portion 22 of the lens 16. In the present embodiment, the height of the step portion 50 is formed to be substantially the same as the thickness of the peripheral side wall of the cap portion 42. Therefore, when the adjustment member 40 is fitted into the tip of the lens holding portion 22 of the optical fiber 16, the lens holding surface 23 of the lens holding portion 22 and the peripheral side wall surface of the cap portion 42 are arranged on substantially the same plane. You. That is, the adjusting member 40 is fitted into the step 50 exactly, and the peripheral side wall surface of the cap portion 42 of the adjusting member 40 stably adheres to the lens 12 surface.

Therefore, in the eyeglass lens mounting structure 10 of the embodiment shown in FIGS. 3 and 4, the adjusting member 40 cooperates with the lens holding portion 22 to be in close contact with a part of the lens 12 surface. In addition, since the contact area between the lens holding portion 22 and the adjustment member 40, that is, the contact area, also increases, the fixation between the lens 16 and the adjustment member 40 is stabilized, and breakage such as hooking of the surface of the lens 12 is prevented. . In the embodiment shown in FIGS. 1 and 2, the through hole 14a of the lens 12 is formed in an elliptical shape, and the insertion columnar body 24 is formed in an elliptical cylindrical body. In the embodiment, as shown in FIG. 6, the through hole 14a of the lens 12 is formed in a circular shape having a diameter of, for example, about 2.0 mm, and the insertion column 24 is formed in a cylindrical shape. The locking recess of the lens 12 is formed by a small hole having a diameter of about 0.8 mm, for example.

FIG. 7 is an enlarged partial cross-sectional view of another example of the eyeglass lens mounting structure according to the present invention when viewed from the plane side of the lens. This embodiment differs from the embodiment shown in FIGS. 1 and 2 particularly when the adjusting member 40 is attached to the tip of the lens holding portion 22 of the lens 16. The close contact member 52 is disposed between the first and second surfaces. The close contact member 52 is disposed between the lens holding surface 23 and the lens 12 surface while being interposed at the base of the insertion columnar body 24. The contact member 52 has the same structure, operation and effect as the contact member 32 shown in each of the above-described embodiments, but in this embodiment, in particular, in this embodiment, the contact portion between the lens holding portion 22 and the lens 12 surface is provided. And the lens holding surface 23 is firmly adhered to a part of the lens 12 surface. In this case, the frictional surface between the contact member 52 and the surface of the lens 12 increases, so that the contact member 52 also functions to prevent the torsion 16 from loosening.

In each of the above-described embodiments, the cap portion 42 of the adjustment member 40 is formed in a cylindrical shape with a bottom. However, the shape of the cap portion is not limited thereto. For example, as shown in FIG. It may be formed by a cap portion 54 having a semicircular cylindrical cross section, or may be formed by a bottomed cylindrical body 56 having a U-shaped cross section as shown in FIG. Further, in the adjusting member 40 shown in FIGS. 8 and 9, the open portions 54a and 56a are respectively arranged upward, but the cap portions 54 and 56 are so arranged that the open portions 54a and 56a are respectively directed downward.
