In this embodiment, a description will be given of a mounting structure of a lens and, for example, Ji as an example of a frame constituent member.

The frameless glasses 10 according to the present embodiment include a lens 12. The lens 12 has a lens hole 14 having a circular cross section, for example, near the edge. The lens hole 14 penetrates from one main surface of the lens 12 to the other main surface. Further, the lens 12 has a locking recess 16 as a first rotation preventing means. The locking recess 16 is formed, for example, by a locking hole having a bottom and a circular cross section. The locking recess 16 is provided at a position separated from the lens hole 14 by a predetermined distance. The locking recess 16 is provided closer to the edge of the lens 12 than the lens hole 14. In this case, the lens hole 14 and the locking recess 16 are arranged at a predetermined interval in the length direction (long axis direction) of the lens 12. The line connecting the center of the lens hole 14 and the center of the locking recess 16 is formed in a straight line.

Further, the frameless glasses 10 according to the present embodiment include, for example, a wisdom 18 as a frame constituent member. The tongue 18 is connected to a connecting portion 20A that is rotatably connected to a temple (not shown) via a hinge portion or the like, and is connected to the connecting portion 20A by being bent substantially at a right angle. And a contactable portion 20B. The abutment portion 20B is connected to a distal end portion in the longitudinal direction thereof, for example, a disc-shaped lens stopper 22 is connected. The lens stopper 22 has, for example, a circular insertion hole 24 in a front view as a penetrating part penetrating from the one main surface to the other main surface of the contact part 20B at the center thereof. When the diameter of the insertion hole 24 is φ1 and the diameter of the lens hole 14 is φ2, the relationship between the two satisfies the relationship of φ1> φ2.

It has a counterbore 26. The counterbore 26 has substantially the same contour as the head 40 of the insertion member 34 constituting one of the connecting means described later. The counterbore surface 28 of the counterbore 26 is disposed so as to be perpendicular to the center line of the insertion hole 24. The diameter of the counterbore 26 is formed to be larger than the diameter of the head 40 of the insertion member 34 described later, for example. By disposing the counterbore 26, the seating surface 41 of the head 40 of the insertion member 34, which will be described later, is seated on the counterbore 28 and is brought into close contact with the contact portion 20B of the tab 18.

Further, a locking projection 30 as second rotation preventing means is provided at the contact portion 20 B of the tongue 18 at a predetermined distance from the center line of the insertion hole 24. In this case, the locking projection 30 is disposed on the opposite surface of the contact portion 20 </ b> B facing the one main surface of the lens 12. The locking projection 30 is formed of, for example, a substantially cylindrical tubular body. The distance between the center of the insertion hole 24 and the center of the locking projection 30 is formed to be substantially the same as the distance between the center of the lens hole 14 and the center of the locking recess 16.

Further, the frameless eyeglasses 10 according to the present embodiment have a connecting means 32 for connecting the lens 12 and a frame component such as the lens 18. The connecting means 32 is inserted into the insertion hole 24 of the contact portion 20 </ b> B from one main surface side of the lens 12, and is inserted into the lens hole 14 from the other main surface side of the lens 12 and cooperates with the insertion member 34. And a fixing member 36 for fixing the frame constituting member such as the wi 18 to the lens 12.

The insertion member 32 includes, for example, a shaft 38 having a bottomed cylindrical shape, and a screw surface 38 a made of, for example, a female screw is formed on an inner peripheral surface of the shaft 38. At one end of the shaft portion 38 in the axial direction, for example, a head 40 having a substantially circular cross section is formed integrally with the shaft portion 38. The diameter of the head 40 is formed smaller than the diameter of the counterbore 26, and the thickness of the head 40 is formed substantially equal to the depth of the counterbore 26. The total length of the insertion member 32 in the axial direction, that is, the total length of the shaft portion 38 in the axial direction and the thickness of the head portion 40 is equal to the depth of the insertion hole 24 and the depth of the counterbore 26. It is formed approximately the same as the combined depth.

The fixing member 36 includes, for example, a cylindrical shaft portion 42, and a screw surface 42 a made of, for example, a male screw is formed on an outer peripheral surface of the shaft portion 42. At one end of the shaft portion 42 in the axial direction, for example, a head portion 44 having a substantially circular cross section is formed integrally with the shaft portion 42. A slit 46 is formed in the head 44. In this case, as the fixing member 36, for example, a slotted small screw and a set screw can be used.

In the mounting structure of the frameless members 10 of the frameless glasses 10 according to the above-described embodiment, the lens 18 is opposed to the lens 12 on one main surface side. Then, a locking projection 30 protruding from the contact portion 20 is inserted into the locking recess 16 of the lens 12 and locked. Further, the insertion member 34 is inserted into the lens hole 14 from one main surface side of the lens 12 through the insertion hole 24 of the contact portion 20. Since the hole diameter φ1 of the insertion hole 24 is set to be at least twice as large as the hole diameter φ2 of the lens hole 14, the insertion member 24 can be displaced in the direction connecting the lens hole 14 and the locking concave portion 16, It can be inserted into the insertion hole 24. Further, the fixing member 36 is inserted into the lens hole 14 from the other main surface side of the lens 12. In this case, the fixing member 36 is inserted into the shaft portion 38 of the insertion member 34 inserted through the lens hole 14, and the screw surface 42a of the fixing member 36 and the screw surface 38a of the insertion member 34 are screwed. You.

In the embodiment described above, the screw 18 and the lens 12 are firmly connected by the screwing action of the screw surface 38 a of the insertion member 34 and the screw surface 42 a of the fixing member 36. At the same time, the rotation of the tongue 18 is prevented by the engagement / locking action between the locking concave portion 16 and the locking convex portion 30.

Further, as shown in FIGS. 1 and 2, the insertion hole 24 is displaceably inserted into the insertion member 34 in a direction connecting the lens hole 14 and the locking recess 16 within a range of the hole diameter φ1. It has a degree of freedom. Therefore, even when the lens hole 14 is opened at a position shifted from a predetermined position, for example, at the time of opening the lens hole 14 and / or the locking concave portion 16 in the lens 12, even if the lens hole 14 is opened, as shown in FIG. As shown in FIG. 4 (B), the degree of freedom for appropriately displacing the insertion member 34 within the range of the hole diameter of the insertion hole 24 makes it possible to absorb an error in the dimension between the lens hole 14 and the locking recess 16. Can be. Therefore, it is possible to prevent the lens 12 from being damaged due to an error as in the conventional example.

FIG. 5 is an enlarged front view of a main part of another embodiment of the present invention when viewed from the front side. FIG. 6 is an enlarged perspective view showing an example of an insertion member used in the embodiment of FIG. It is an illustrative view. The embodiment shown in FIG. 5 is different from the above-described embodiment in the structure of the contact portion 20B of the tongue 18, in particular. That is, in the above-described embodiment, the disc-shaped lens stopper 22 is formed at the tip of the contact portion 20B. However, in the embodiment shown in FIG. 5, the length of the contact portion 20B in the width direction is reduced. A lens stopper 48 made of a strip having the same width is formed. Further, the lens stopper 48 is formed with, for example, an elliptical counterbore 50 communicating with the insertion hole 24. The insertion member 34 inserted into the insertion hole 24 via the counterbore 50 has an elliptical head 52 smaller than the contour of the counterbore 50 as shown in FIGS. .

The insertion member 34 is not limited to the one shown in each of the above-described embodiments, but may have a substantially rectangular plate-shaped head 54 as shown in FIG. 7, for example. No. Then, the contour shape of the counterbore portion may be changed according to the shape of the head of the insertion member 34. In this case, if the shape of the head of the insertion member 34 is formed in an elliptical shape, a rectangular shape, a square shape, or another polygonal shape, the insertion member 34 is formed in the contact portion 20B by the cooperative action with the counterbore portion. It will have a detent function.

Further, in each of the above-described embodiments, in the contact portion 20 B of the tongue 18, the penetrating portion is provided with the insertion hole and the counterbore portion, but the counterbore portion is not necessarily provided. Alternatively, only an insertion hole (through portion) penetrating through the contact portion 20B may be provided. In this case, when the insertion member 34 is inserted into the insertion hole (through portion) from the one main surface side of the lens 12, the head of the insertion member 34 comes into contact with the surface of the contact portion 20B around the insertion hole (through portion). The lens 12 is locked so that it does not come off even when pulled from the other main surface side of the lens 12.

FIG. 8 is an enlarged sectional view of a principal part of another embodiment of the present invention when viewed from the plane side, and FIG. 9 is a partially omitted perspective view showing a principal part of the embodiment of FIG. FIG. The embodiment shown in FIGS. 8 and 9 is different from the above-described embodiments in that the penetrating portion is constituted by a penetrating long hole.

In this case, the length of the through-hole 58 in the long axis direction is appropriately set so that the insertion member 34 is inserted so as to be sufficiently displaceable in the linear direction.

In the embodiment shown in FIGS. 8 and 9, the insertion member 34 inserted through the elongated through hole 58 can be freely moved in the longitudinal direction of the elongated through hole 58. Therefore, a dimensional error between the lens hole 14 and the locking recess 16 can be compensated for and absorbed by the through-hole 58 as shown in FIG. 10, for example. That is, when the insertion member 34 is positioned within the through-hole 58, the insertion member 34 has a degree of freedom within the range of the length in the major axis direction. It is possible to absorb a dimensional error between the locking recess 14 and the locking recess 16. Therefore, it is possible to prevent the lens 12 from being damaged due to an error as in the conventional example.

It is to be noted that the through-hole 58 may have a peripheral wall opened to the distal end side of the contact portion 20B. In this case, since a part of the peripheral wall of the through hole 58 is open, the processing of the through hole 58 in the insertion member 34 becomes easy.

In each of the above embodiments, the direction connecting the lens hole 14 and the locking recess 16 is configured to be the same as the long axis direction of the lens 12. The direction connecting and may be configured to be, for example, the short axis direction of the lens 12. In this case, for example, a band-shaped lens stopper (not shown) is disposed at the distal end or intermediate portion in the longitudinal direction of the contact portion 20B. The lens stopper (not shown) is connected in a direction substantially orthogonal to the contact part 20B. Further, for example, an insertion hole 24 or an elongated through hole 58 as a through portion is provided at an intermediate portion in the length direction of the lens stopper (not shown). Then, the insertion member 34 is inserted through the insertion hole 24 or the long through hole 58 so as to be displaceable in the short axis direction of the lens 12.

In each of the above-described embodiments, the shaft portion 38 of the insertion member 34 may be formed in, for example, a polygonal cylindrical shape such as a rectangular shape in section, a rectangular shape such as a rectangle, a pentagonal shape, or a hexagonal shape. Further, the locking recess 16 may be formed in, for example, a through hole or a recess other than the bottomed hole.

In each of the above-described embodiments, by using, for example, a set screw as the fixing member 36, the screw length between the screw surface 38 a of the insertion member 34 and the screw surface 42 a of the fixing member 36 is increased. Can be. Therefore, for example, even if the fixing member 36 is slightly loosened, the tongue 18 does not easily come off the lens.

In the above embodiment, in the embodiment in which the counterbore portion is provided in the penetrating portion, when the seating surface of the contact portion 20B of the tongue 18 is rough, or the material of the tongue 18 is aluminum, When formed of a soft material such as a rubber-based resin material, a washer or the like can be used because it needs to be supported on a wide surface. Accordingly, it is possible to prevent the insertion member 34 and the fixing member 36 from being loosened due to vibration or the like due to an external force. As the washer, for example, a flat washer may be used, and a spring washer, a toothed washer, a tongue washer, a rubber washer, or the like may be used as appropriate to prevent loosening.

Further, in each of the above-described embodiments, as an example of the frame constituent member, the mounting structure of the lens 18 and the lens 12 has been described. However, the present invention can be applied.
