Description

[Detailed Description of the Invention] This invention relates to a lens fixing piece for an eyeglass frame, which is used when attaching a lens to an eyeglass frame.

In recent years, the number of people who prefer large eyeglass frames has been increasing, but not everyone can wear large frames, and the size of the eyeglass frames that should be worn is related to the wearer's interpupillary distance. This is something that is naturally determined, and large frames are only suitable for people with wide eyes.

First, with reference to FIG. 1, we will explain why large frames are undesirable for people with narrow interpupillary distance. In FIG. 1, 1, 1 are left and right frames. a, a indicate the frame geometric center, and the frame geometric center is the intersection of the horizontal line connecting the center of the widest part in the vertical direction of frame 1 and the vertical line connecting the center of the widest part in the horizontal direction means. Further, b and b indicate the positions of the left and right pupils of the wearer, and the interpupillary distance l is between b and b. A shows a fabric lens, and the fabric lens A should be cut to fit frame 1 with its optical center aligned with the center of the pupil. By the way, fabric lenses do not come in various sizes; there is only one type of lens on the market, and the diameter of the most common fabric lens at present is 65 mm.
Therefore, the wearer cannot choose any frame size, and the frame size is automatically determined according to the wearer's interpupillary distance. If a person with narrow eyes tries to choose a large frame size, the fabric lens A will be too small for the frame 1, as shown in FIG. 1, and a gap will be created on the outside. The object of this invention is to provide a lens fixing piece for eyeglass frames that allows even people with narrow pupil distance to use a large frame by fitting the fixing piece B into the gap.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 2 shows a first embodiment of this invention, in which 1, 1 are left and right frames. Lenses 2, 2 cut out to fit into the frames 1, 1 are fitted inside the frames 1, 1, respectively.
Since large frames are used as the frames 1, 1, there are gaps between the inner peripheries of the outer parts of the frames 1, 1 and the outer peripheries of the outer parts of the lenses 2, 2, respectively. Mounting pieces 3, 3 are attached to the outer parts of the frames 1, 1 by brazing, respectively, and frame legs 4, 4 are attached to the rear end sides of the attachment pieces 3, 3 so that they can be folded inward. There is. Fixing pieces B are fitted into the gaps between the frames 1, 1 and the lenses 2, 2, respectively, and the fixing pieces B have a shape as shown in FIG. That is, the fixed piece B has a slightly elongated shape, and a V-shaped groove 5 is provided on the side edge, and a U-shaped groove 6 is also provided on the side edge opposite to the groove 5. Further, notches 7, 7 are provided on the side where the groove 6 is provided in a direction perpendicular to the groove 6.

To install this fixing piece B, first loosen the screws that fasten the frame 1 at the mounting piece 3 position, loosen the frame 1, fit the groove 5 of the fixing piece B onto the outer periphery of the outer part of the lens 2, and attach the other The groove 6 is fitted into the inner periphery of the outer part of the frame 1. At this time,
Make sure that the mounting part of the mounting piece 3 fits into the notches 7, 7 of the fixed piece B, but if you tighten the loosened screws again in this state, the fixed piece B will fit into the frame 1.
There is a gap between lens 2 and lens 2.
is definitely fixed. This state is clearly shown in FIG. 4, which is a sectional view taken along the line "-" in FIG. One groove 5 of the fixing piece B fits into the outer periphery of the lens 2, and the other groove 6 fits into the inner periphery of the frame 1, ensuring secure fixation. When the fixing piece B is attached on the other side in the same manner, the state shown in FIG. 2 will be obtained.

Next, a second embodiment of this invention will be explained with reference to FIG. The fixed piece B of the second embodiment has a substantially U-shape as a whole, and has legs 8, 8 formed at the upper and lower ends, respectively, and the legs 8, 8 are connected by a connecting rod 9. . Grooves 6, 6 are provided on the front end sides of the legs 8, 8, respectively, and a groove 5 is provided on the side edge on the opposite side to the side on which the legs 8, 8 are formed. In the second embodiment, since the area in contact with the frame 1 is reduced, the frame 1 can be firmly attached even to a considerably curved part.

Next, a third embodiment of this invention will be explained with reference to FIG. The fixing piece B of the third embodiment connects the upper leg 8 and the lower leg 8 at their centers by a connecting rod 9, and has a substantially I-shape as a whole. Grooves 5, 5 are provided on one end side of the legs 8, 8, and grooves 6, 6 are provided on the other end side, and the connecting rod 9 is made thin.
In this way, it can be attached to a position where the frame 1 or lens 2 has a large degree of curvature.

Next, a fourth embodiment of this invention will be explained with reference to FIG. The fixing piece B of the fourth embodiment has legs 8 only on the upper side, and has a generally inverted L-shape as a whole. A notch 10 is provided on the side of the leg 8. A groove 6 is formed on the side edge of the side where the leg 8 is formed.
A groove 5 is provided on the side edge of the other side. By fitting it into the notch 10 from the front side of the frame 1, the fixing piece B is made difficult to come off.

Next, a fifth embodiment of this invention will be explained with reference to FIG. The fixing piece B of the fifth embodiment has a groove 6
A triangular protrusion 11 is formed at the back of the frame 1 to fit into a triangular groove formed on the inner periphery of the frame 1.

In the sixth embodiment shown in FIG. 9, only triangular protrusions 11 are formed without providing grooves 6.

The seventh embodiment shown in FIG. 10 is almost the same as the fourth embodiment shown in FIG. 1 more firmly.

In the eighth embodiment shown in FIG. 11, although the groove 6 is U-shaped, the other groove 5 is not formed but has a triangular protrusion 13, and the lens 2
A triangular groove is formed on the outer periphery of the protrusion 1.
3 into the groove.

In the ninth embodiment shown in FIG. 12, the groove 6 is made into a U-shape, and a protrusion 11
, and a triangular protrusion 13 is formed on the other side edge.

In the tenth embodiment shown in FIG. 13, a protrusion 11 is formed on one side, and a protrusion 13 is formed on the other side.

In the eleventh embodiment shown in FIG. 14, a device is devised to make the fixing of the fixing piece B even more secure. That is, a wire-shaped holding piece 14 is attached to the back side of the fixed piece B, and the tip of the holding piece 14 is rounded to form a ring 15. And that ring 1
5 to the upper surface of the hinge 16 as a folding mechanism of the frame leg 4, and insert the hinge screw 17 from the ring 15 to the hinge 1.
6, the fixing piece B is held by the hinge 16. When held in this manner, the holding piece 14 prevents the fixed piece B from moving in the vertical direction, so that the fixed piece B is firmly fixed.

Although various embodiments of this invention have been shown above, the embodiments of this invention are not limited to those shown above. For example, fixed piece B
A V-shaped groove 5, a U-shaped groove 6, and a U-shaped notch 1 are provided on opposite side edges of the
0. Triangular protrusions 11, 13, etc. are provided so that the lens 2 can be fitted onto the outer periphery of the outer part of the lens 2 cut to be fitted into the frame 1, and the inner periphery of the outer part of the frame 1. ,
Various other shapes can be considered for the opposing edges of the fixed piece B, and in any case, the shape of the lens 2
It is sufficient if the unevenness has a shape that fits into the outer periphery of the outer part of the frame 1 or the inner periphery of the outer part of the frame 1. In this specification, the term "unevenness" is used not only to include both concave portions and convex portions, but also to include only one of concave portions and convex portions.

The fixing piece B can also be made into a fashion-like design, or can be colored in whole or in part to create a fashion-like decoration.

As is clear from the above, according to the lens fixing piece for eyeglass frames according to the invention, one side edge is joined to the outer periphery of the outer part of the cut lens 2 while the other side edge is attached to the inner circumference of the outer part of the frame 1. The installation work is easy, as it can be installed by simply fitting it around the circumference. After attachment, one side edge is pressed against the outer periphery of the lens 2, and the other side edge is pressed against and fitted into the inner periphery of the frame 1, so that the lens 2 is firmly fixed within the frame 1. By using this fixing piece, even people with narrow interpupillary distance can wear large eyeglass frames.

In addition, the thickness of the fabric lens gradually increases from the center to the outer circumference, but when this fabric lens was cut to fit the frame size, the outer circumference was too thick, making it difficult to fit into the frame. It may become difficult to use, or it may become unbalanced with the frame, resulting in an unsightly appearance.
In such a case, cut an extra part of the fabric lens to reduce the thickness of the outer periphery, and then use the fixing piece B according to this invention on the extra cut part to firmly fix the lens. It can also be done.

When this fixing piece B has a fashion-like design shape or is colored in whole or in part to create a fashion-like decoration, the space between the outer part of the frame 1 and the outer part of the lens 2 This gap can be used for fashion purposes. It is sure to attract the attention of consumers as it creates a new type of fashion that has never existed before.

If a notch 7 is provided on the outside of the frame 1 to avoid the mounting piece 3 fixed, and the fixed piece B is fixed so that the mounting piece 3 is located within the notch 7, even if the fixed piece B is Even if it tries to move downward, the upper edge of the notch 7 hits the mounting piece 3 and prevents it from moving downward, so that the fixed piece B is firmly fixed. In particular, when the width of the notch 7 is made almost the same as the width of the mounting piece 3, vertical displacement is prevented, which further strengthens the fixation.
