[Industrial use]

The present invention relates to eyeglasses having a single-eye lens (left and right lens) that can be used as sunglasses, protective glasses, and the like.

[Prior art]

Conventionally, sunglasses illustrated in FIGS. 16 and 17 are generally used as sunglasses having a single-eye lens (see, for example, US Patent No. 4,824,233).

This sunglasses 41 has a single transparent plate-like lens 42 having a curved surface, one frame 43 having a length over the full width of the upper edge of the lens 42, and fitted and fixed to the lens, It consists of a leg 44 which is freely foldable and detachably attached to the left and right outer ends of the frame 43, and a substantially reverse V-shaped nose ring fitting portion 47 is formed in the lower part of the center bridge of the lens 42. It is installed, the nose ring member 46 is fitted.

In addition, an inner frame having a power lens, a light shielding lens, or the like may be attached to the central bridge rear surface of the lens 42 through a suction hole such as a sucker.

[Problems that the invention tries to solve]

By the way, since the conventional sunglasses have a frame 43 of a length over the full width of the upper edge of the lens 42, it is difficult to fit to the head of the wearer whose shape and size vary widely, and cannot be fitted snugly, In addition, there is a problem that the frame 43 narrows the front view of the wearer, and is difficult to see the front when the vehicle is in an inclined forward position, particularly when riding a bicycle.

In addition, although the adsorption port is used for the attachment of the inner frame, if the adsorption state is bad, the adsorption port is not only dropped immediately but also has a problem of being easily peeled off due to the decrease in the adsorption force.

The present invention has been made in view of the above-described situation, and its purpose is to make the lens elasticity to fit the wearer's head with moderate softness, and to widen the front field of view, It is to provide one-eyes glasses which putting on and taking off is simple and does not come off naturally naturally.

[Means for solving the problem]

In the present invention, the following technical means have been devised in order to achieve the above object.

That is, the present invention provides a shock-resistant plastic monocular lens such as polycarbonate, a pair of left and right frames fixed to the upper edges of both ends of the lens, and a pair of left and right legs freely attached to the outer ends of both frames. It is characterized in that the width of the fixing portion between each of the frames and the lens is 8 to 30% of the width (circumference length) of the upper edge of the lens.

In addition, the present invention is the nose ring member fitting portion is formed in the lower portion of the center bridge of the lens, the nose ring member having an inner frame engaging portion is detachably fitted to the fitting portion, the inner frame fitting portion inner frame It is characterized in that the engaging portion of the freely mounted.

[Action]

According to the present invention, since the frame is fixed to both ends, the single-eye lens can secure moderate softness without losing its elasticity, and thus fits the head of the wearer.

In addition, the front field of view is not obscured by the frame, so that the front field of view can be sufficiently secured even in a posture tilted forward when the magnetron is taken.

In addition, the engaging portion of the inner frame can be easily detached from the inner frame engaging portion provided on the nose ring member, and both engaging portions are not peeled off unless the inner frame is actively removed, so that the inner portion can be safely worn.

In addition, in the case where the single-lens lens has a large amount of transmitted light as it is moved away from the center point concentrically with the upper portion of the center bridge as a center point, the portion having high water sensitivity at the center of the retina is faced with a relatively small amount of light. The front image is projected so that the relatively low-light portion away from the center of the retina is reflected by the left and right scenes with a relatively large amount of light, so that a uniform image can be obtained over the entire field of view.

EXAMPLE

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described based on drawing.

1 and 2, 1 is sunglasses, a flexible one-lens lens 2 having a flexible and elasticity having an appropriate curved surface, for example a six curve spherical surface, and an upper edge of both ends of the lens 2; It consists of a pair of left and right frames 3 and 3 fixed to the side, and a pair of left and right pairs of legs 4 and 4 freely attached to the outer ends of both frames 3 and 3. The one-eye lens 2 is made of impact-resistant plastic such as polycarbonate and ABS resin, and polycarbonate is best.

The spherical surface of the six curves is the radius of curvature Rl (mm) of the front surface of the spherical surface,

R1 = (N-1) × 100 / D [D = 6]

It is a sphere set by. Where N is the refractive index of the material, and in the case of polycarbonate it is approximately 1.586.

The nose pad member fitting portion 5 is formed in a cut-out shape in a substantially inverted V shape at the lower portion of the center bridge of the lens 2, and the nose pad member 6 can be detachably inserted and attached to the central bridge. In the upper end edge 2A, the sweat stop portion 7 or the visor portion 8 (see Figs. 8 and 9) can be detachably fitted.

Screw holes (not shown) are provided in the left and right upper end portions of the lens 2, and the frames 3 and 3 are detachably fixed by the screws 9.

In the lower part of the fixed part of this frame 3 and 3, the notch part 32 is formed in the left and right ends of the lens 2, and the lens is attached by the frame 3 and 3 fixed to the lens 2; The deformation of (2) is prevented from being suppressed as much as possible.

The heights of the fixing portions of the frames 3 and 3 and the lens 2 are gradually increased from the left and right center side toward the left and right sides, thereby widening the field of view on the left and right center side, thereby increasing the support strength of the lens 2. It is trying to improve.

In addition, both frames 3 and 3 have a width (length) of the upper edge portion of the lens 2 as shown in FIG. 2 of the width (length) W2 of the fixing portion between the lens 2 and the lens 2. It is designed to be 8 to 30% of (Wl). When the width W2 of the fixing portion is less than 8% of the width Wl of the upper edge of the lens, the support strength of the lens 2 cannot be secured, and 30% of the width Wl of the upper edge of the lens is secured. If it exceeds, the front field of view of the wearer is not only narrowed, the flexibility of the lens 2 is limited, and proper softness cannot be secured, so the range of 8 to 30% is most suitable.

Moreover, it is good to design so that the maximum height h of the fixed part of the frame 3 and the lens 2 may be 3 mm or more and 15 mm or less. This is because if the maximum height h is less than 3 mm, the supporting strength of the lens 2 cannot be secured, and if it exceeds 15 mm, the front view of the wearer is obstructed.

Moreover, the leg attachment parts 10 and 10 protrude from the outer edge back surface of the frames 3 and 3, respectively, and the engaging shaft hole 11 which penetrates up and down in the attachment part 10 is provided, The front end attachment portion 12 of the legs 4 and 4 in the shape of the two legs is fitted out so as to fit the leg attachment portion 10 from the top and bottom, and protrudes on the upper and lower facing surfaces of the front attachment portion 12. The installed shaft portion 13 is rotatably fitted into the engagement shaft hole 11, and the legs 4 and 4 are in contact with the outer end 3A of the frame 3 so as not to rotate outward any more. Although the angle of expansion is regulated, it is free to fold on the opposite side. The legs 4 and 4 are preferably flexible and elastic.

As shown in FIGS. 2 to 4, the legs 4 and 4 penetrate left and right from the substantially central portion in the longitudinal direction to the rear (the earring portion side), and are provided with a non-slip mounting length having a locking protrusion 14. The hole 15 is provided, and the non-slip tool 16 made of an elastic material such as rubber is fitted, and the anti-slip tool 16 is formed in a generally hemispherical shape on the opposite inner surface of the non-slip tool 16, i.e., the face of the wearer. The protrusion 17 is provided, and the protrusion 17 protrudes from the opposing inner surface 4A of the legs 4 and 4.

In addition, when the lens 2 is spherical and the distance between the left and right legs 4 and 4 increases when the glasses are worn together with the flexible legs 4 and 4, the front surface of the spherical lens 2 is thus horizontal. The radius of curvature rl in the direction is increased, and the head part is smoothly wrapped by the elasticity of the lens 2 and the legs 4 and 4.

That is, in the present embodiment, the distance between the rear ends of the left and right legs 4 and 4 in the state where the legs 4 and 4 are maximized and laid naturally quietly to the maximum is 1 cm. (2) The horizontal curvature radius of the front surface is rl, and the distance between the rear ends of the left and right legs 4 and 4 is opposed to the elasticity of the lens 2 and the legs 4 and 4 so that the distance is When the radius of curvature in the horizontal direction of the front surface of the lens 2 when r1 is 3 + 3 is r3, r1 x 1.03 r3 It is configured to satisfy the relationship of r1 × l.35.

In this case, when the radius of curvature (r3) after opening is less than r1 × 1.03, the elasticity (spring force) surrounding the head part is almost dependent on the elasticity of the legs 4 and 4, and the head part is the head part when the wearer has a large head part. The legs 4 and 4 may be tightened, resulting in frustration, and the leg attachment portion 10 of the frame 3 may be damaged. On the other hand, when the radius of curvature r3 after opening exceeds r1 x 1.35, the elasticity (spring force) for fitting the head is insufficient.

The nose ring member 6 is composed of a hard plastic support 6A that is substantially V-shaped from the front, and a nose pad 6B made of soft rubber, as shown in FIGS. An engaging portion 19 having an inner frame engaging projection 18 is integrally projected on the front surface of the center 6A of the support 6A, and the upper portion of the support 6A except for the engaging portion 19 is installed. In the circumferential surface, the fitting groove 20 is recessed closer to the front side than the fitting portion 19, and the fitting groove 20 is inserted into the fitting portion 5 of the lens 2 to be fitted out. have.

Then, a plurality of fitting holes (not shown) are provided on the back surface of the support 6A, and the engaging projection 21 protruding in front of the nose pad 6B is inserted into the fitting hole, and the support 6A is inserted into the support 6A. The nose pad 6B is engaged and integrated. And the nose pad 6B can be fixed to 6 A of support bodies with an adhesive agent.

As shown in FIG. 8, the sweat stop portion 7 is made of a plastic attachment portion 7A and a sponge material (foamed synthetic resin or foamed rubber) adhered to the back surface of the attachment portion 7A. It consists of a sweat stop 7B, and the fitting groove 22 is recessed in the lower part of the attachment part over the entire length, and the fitting groove 22 is attached to the upper end edge 2A of the lens 2. Desorption is freely possible. And it is good to employ | adopt this sweat stop part 7 so that it can be bent so that the flexibility of the monocular lens 2 may not be lost.

And, as shown in FIGS. 9 and 10, the sweat stop portion 7 is connected to the upper end of the inner frame engaging portion 19 of the nose pad member 6, and can be integrated with the nose pad member 6. have.

As the sweat stopper 7B, as shown in FIG. 10, a continuous bubble-type absorbent sponge body 23 and an independent bubble-type sponge body 24 can be used as an integral one.

As shown in FIG. 8, the visor portion 8 is formed at both cutout portions 8A of the rear corner corners with the engaging portions 25 at the upper end edges 2A of the lens 2 facing downward. Hanging on the end edge 2A, it is possible to freely bond.

11 to 15 show the inner frame 26, and FIGS. 11 and 12 show the entire rim 27 made of plastic, and a power lens or light blocking lens attached to the rim 27, and the like. It is made of a lens 28, the bridge portion 29 in the center of the rim is projected to the front, as shown in Figure 12, the engaging portion 30 of the upper and lower two holes are provided in the center thereof In addition, the left and right outer edge portions 27A of the rim 27 have a curve of curvature stronger than that of the spherical surface that is lightly in contact with the back curved surface of the single-eye lens 2 and approximately equal to the curvature of the curved surface ( Hereinafter referred to as 6 curve design).

In addition, the inner frame 26 can freely engage the engaging portion 30 with the engaging protrusion 18 of the engaging portion 19 of the nose hanger member 6, and the sunglasses (if necessary) It is attached to 1) and can be easily peeled off when it is unnecessary.

The inner frame 26 shown in FIG. 14 is provided with nylon yarns to support the lens 28 in place of the outer and outer halves of the rim 27, and the inner frame shown in FIG. 26 is a perforated frame type, and the rim 27 is fixed to the lens 28 by the bis 31.

The engaging portion 30 is provided on the bridge portion 29 of the rim 27, and the left and right outer edge portions 28A of the lens 23 have six curve designs.

In addition, the inner frame engaging portion 19 provided in the nose pad member 6 may be formed into each hole in place of the engaging protrusion 18, and the engaging portion 30 of the inner frame 26 may be formed into each hole. It can be used as a catch instead.

In addition, since the inner frame 26 adopts a six-curve design, it is possible to secure the maximum lens surface required while satisfying the spectacle optical conditions for maintaining the inner frame lens surface at a right angle to the line of sight. The engaging portion 19, which is an attachment part to the nose, is easily detachable from the nose ring member 6, the attachment processing of the lens 28 is easy, and it is easy to wipe off dirts and the like. Can be used.

In addition, a dye film or a vapor deposition film may be coated on the surface of the lens 2 to adjust the amount of transmitted light over the entire front surface of the one-eye lens 2 of the above embodiment. In this case, the thickness of the dye or vapor-deposited film is thickest at and near the center point of the center bridge portion of the lens 2, and becomes thinner concentrically as it moves away from the center point, and concentric circles around the center bridge upper part. It is advantageous to increase the amount of transmitted light as it moves away from the center point. In this way, when the spectacle wearer needs to put the left and right forward view in the field of vision while looking directly at the front front image such as sports games, the front front image is reflected at a relatively small amount of light in the portion where the water surface has high sensitivity. The left and right scenes are reflected by a relatively large amount of light on the relatively low retinal portion deviated from the lens, so that a uniform image can be obtained without oversight over the entire field of view.

According to this embodiment, the one-eye lens 2 is flexible and secures a pair of left and right frames 3 and 3 to the upper edges of the left and right ends of the lens 2, and the left and right frames 3 and 3 are fixed. Since the left and right pairs of legs 4 and 4 are freely foldable at the outer ends of the frames, appropriate softness can be secured without losing the flexibility of the single-eye lens 2 by the frames 3 and 3, It can be fitted to the user's head and can also widen the front view of the wearer.

In addition, since the non-slip tool 16 is attached to the leg 4, the glasses can be prevented from slipping off and replaced with non-slip devices 16 having different thicknesses to fit the head of each wearer. It can be set to make it fit, and a number of color changes can be made by replacing the slipper 10. As shown in FIG. In addition, since the nose pad 6B is also free to be detached and set, the wearer 6B can be set according to each wearer by replacing it with a different thickness.

The present invention is not limited to the above embodiment, and the design can be changed as appropriate.

For example, it can employ | adopt as various protective glasses other than sunglasses.

In addition to the spherical surface, the lens 2 may be bent at a predetermined curvature radius in the horizontal direction, and may be curved at a predetermined curvature radius different from the curvature radius in the horizontal direction in the vertical direction. As described above, if the lens 2 is curved in the horizontal and vertical directions, the elasticity of the lens 2 can be improved and the strength can be made good.

[Effects of the Invention]

As described above, the present invention provides a shock-resistant plastic first-eye lens, such as polycarbonate, a pair of left and right frames fixed to upper edges of both ends of the lens, and a left and right pair freely attached to the outer ends of both frames. And the width of the fixing portion between each of the frames and the lens is 8 to 30% of the width (circumference length) of the upper edge of the lens, so that it is suitable without losing the elasticity of the lens itself. The softness makes it possible to fit the wearer's head by the spring and to widen the front view of the wearer. Therefore, it is possible to widen the front field of view in the forward tilted position when riding a motorcycle or sports.

In addition, the present invention is the nose ring member fitting portion is formed in the lower portion of the center bridge of the lens, the nose ring member having an inner frame engaging portion is detachably fitted to the fitting portion, the inner frame fitting portion inner frame It is characterized in that the engaging portion of the fitting is detachably mounted, so that the inner frame can be easily and reliably mounted when necessary, and can be easily removed when it is not needed, so that the inner frame may fall unintentionally and be damaged. Furthermore, it can be mounted stably.

However, since the present invention is characterized in that the sweat stop portion or the visor portion is detachably mounted on the upper edge of the center bridge of the lens, the sweat stop portion is attached as necessary to prevent sweat from entering or flowing into the eye. In addition, by attaching the visor portion, it is possible to prevent sunlight from covering the lens as well as to block sunlight, thereby ensuring a good timepiece.

In addition, the present invention is characterized in that the sweat stop portion is integrally installed in the upper portion of the nose pad member, the nose pad member can be inserted from the top and bottom of the bridge portion of the lens, so that the mounting can be secured and At the same time, the mounting state of the inner frame can be further stabilized.

In addition, according to the present invention, since the single-eye lens has a large amount of transmitted light as it is moved away from the center point concentrically with the upper portion of the center bridge as the center point, the wearer can obtain a uniform image over the field of view.
