Regarding a light-shielding lens.

[0002]

2. Description of the Related Art In recent years, eyeglasses having various functionalities have been demanded. For example, eyeglasses with light-shielding properties have been put on the market to protect the eyes. Specifically, a deflection lens for blocking ultraviolet rays and the like is used for the lens of the spectacle body.

However, if a light-blocking lens such as a deflecting lens is used as the spectacle body lens, it becomes a colored lens, which gives an unnatural appearance. Therefore, spectacles capable of providing a light-shielding function only when needed are preferred. It uses a so-called shading device and can be attached to the main body of the glasses when necessary.
Can be removed when not needed.

By the way, as a means for attaching the light shield to the spectacle body, there are an improved rim of the eyeglass, and a light shield provided with a fixing tool that can be attached to the eyeglass. The former is such that holes are added to the rim of the spectacles body, and it does not look good in appearance and is not necessarily preferable. In the latter, since it is attached via a fixing tool, there is an advantage that the main body of the glasses is not damaged, and this method has become the mainstream at present.

FIG. 10 shows a conventional shading device provided with a fixture for attaching to spectacles. This shading device is provided with two L-shaped fixing devices around the shading lens,
A total of four fixtures are fixed to the two light-shielding lenses.
The transition body for connecting the two lenses is formed integrally with a fixture fixed to the upper side of the light blocking lens. A screw hole is provided in the base of the fixture that contacts the light-shielding lens, and the fixture is attached to the light-shielding lens through the screw hole using a screw or the like (see FIG. 10B). The support part bent substantially at a right angle from the base part is a part for supporting the rim of the spectacle body or the lens directly.

By the way, since this shading device is fixed by using a screw or the like when the fixing device is attached to the shading lens, if a force is applied to the shading device with the shading device attached to the eyeglass body, the shading lens will be There is a risk of cracks and other cracks.
Similarly, if a relatively strong force is applied to the shading device, and the component force in the direction of the shading lens surface is generated in the fixing device, the fixing device may slide along the lens peripheral surface with the screw fastening portion as a fulcrum. is there. That is, the fixture is displaced from the lens peripheral surface.

When such a shift occurs, when the light-shielding device is attached to the eyeglass, it is loose and unstable. From the above, there has been a demand for a light-shielding tool that does not cause cracking of the light-shielding lens or displacement of the fixing tool even when force is applied to the light-shielding tool attached to the eyeglass body.

[0008]

The present invention has been developed based on such a technical background. That is, an object of the present invention is to provide a light-shielding tool that does not cause cracks in the light-shielding lens and displacement of the fixing tool, and further to provide a fixing tool, a light-shielding lens, and a transition which are the components thereof.

[0009]

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings by giving specific examples. FIG. 1 is a diagram showing a light shield S of the present invention. The light shield S is used by being attached to the spectacle body G in a front-hanging manner, and includes a light shield lens C,
The transition body B, the fixture A, etc. are components. Shading lens C
, A total of two fixtures A are fixed, one on the upper side L1 and one on the outer side L2 or the lower side L3. The two light-shielding lenses C on the left and right are joined by a transition body B attached to a fixture A on the upper side L1.

First, the light-shielding lens C is shown in FIG. The light blocking lens C is provided with a cutout portion 31 on the lens peripheral surface. Further, an independent hole portion 32 is provided at a position on the inner side at a constant distance from the cutout portion 31. The shape of the hole 32 may be circular or rectangular.
The protrusion 3A of the fixture A, which will be described later, has a corresponding shape into which the protrusion 3A can be fitted. The notch 31 is provided at one place on the upper side L1 of the light shielding lens C, and on the outer side L2 or the lower side L3.
It will be installed at two locations, one at each location. Therefore, the holes 32 are also provided at two places corresponding to the cutouts 31.

Next, the fixture A will be described with reference to FIGS. 4 and 5. The fixture A is for attaching the light shield S to the spectacle body G, and is made by injection molding of ABS resin (trade name: DURACON), for example. The fixture A is attached and fixed to the notch 31 and the hole 32 provided on the upper side L1 and the outer side L2 or the lower side L3 of the light blocking lens C described above. The fixture A is the upper side L of the light-shielding lens C.
The first fixture A1 fixed to the cutout portion 31 and the hole portion 32 provided in No. 1 and the second fixture fixed to the cutout portion 31 and the hole portion 32 provided in the outer side L2 or the lower side L3. There is a fixture A2.

FIGS. 4A and 4B show the first fixture A1. FIG. 4A is its front view, FIG. 4B is its side view, FIG. 4C is its bottom view, and FIG. 4D is its perspective view. Show. The first fixture A1 includes a base portion 1 and a support portion 2 bent from the base portion 1, and forms an L shape as a whole. The base 1 is provided with a protrusion 3 at an intermediate position, and the protrusion 3 is divided into two to form a divided portion.

The tip of this divided portion is provided with a locking portion 3A so as to be engaged with the hole 32. Therefore, since the protrusion 3 is expandable and has an elastic force, it can be inserted into the hole 32 of the light-shielding lens C and can be elastically locked accurately.
In this case, if the hole 32 is rectangular as described above, the protrusion 3 is also rectangular so as to correspond thereto. If the hole 32 is round, the protrusion 3 is also round (see FIGS. 6A and 6B).

A claw 4 is provided at the end of the base 1 in the same direction as the protrusion 3, and the claw 4 can be fitted into the cutout 31 of the light-shielding lens C. This claw part 4
By fitting into the notch 31, the fixture A is prevented from shifting along the peripheral surface of the light-shielding lens C. When the hole 32 and the protrusion 3 are rectangular, the protrusion 3 is fitted in the hole 32, and the function of preventing the shift by the claw 4 prevents the fixing tool A from rotating and prevents the shift. The effect can be exerted more.

Further, a lateral hole 5 is provided in the thickness portion of the base portion 1, and a tip of a transfer body B, which will be described later, can be inserted into the lateral hole 5 to be elastically fixed. Since the tip of the supporting portion 2 bulges inward, the bulging portion (bulging portion 6) and the base portion 1
The eyeglasses can be accurately supported between and. On the other hand, the second fixture A2 is fixed to the outer side L2 or the lower side L3 of the light shield S, and has no lateral hole for attaching the transition body B.

FIG. 5 shows the second fixture A2. (A) is its front view, (b) is its side view, (c) is its bottom view, and (d) is its perspective view. Show. The second fixture A2 does not have a large area at the base portion 1 like the first fixture A1 and is as inconspicuous as possible when viewed from the front (see FIG. 1). FIG. 3 shows the transfer body B. The transition body B is made of a highly elastic metal wire made of stainless steel or the like, and can connect the left and right two light-shielding lenses C together.

Both ends of the transition body B are bent into a step shape 21, and the U-shaped hook portion 22 is formed by bending back the bent portion of the step shape 21. The reason for bending this step-like shape 21 is that when the transition body B is attached to the light-shielding lens C via the fixture A, the transition body B is placed at an upper position so as not to be in the visual field as viewed from the front. This is because I want to put it. Therefore, it is not always necessary to form the step 21.

Since the U-shaped hook portion 22 of the transition body B has an elastic force, the hook portion 22 has been described above.
When it is inserted into the lateral hole 5 provided in the base portion 1 of the fixture A, it is elastically fixed. Therefore, the bridging body B, which has been elastically fixed to the fixing tool A, does not come off in a degree that is normally used, but the hook portion 22 can be pulled out from the lateral hole 5 by strongly pulling it out.

Next, the procedure for assembling the light shield S will be described with reference to FIG. Two light-shielding lenses C which are components of the light-shielding tool S, two first fixing tools A1, two second fixing tools A2, and one transition body B are prepared. First, first, the protrusion 3 of the fixture A is inserted into each hole 32 of the light-shielding lens C and locked. Then, the claw portion 4 of the fixture A is accurately fitted into the cutout portion 31 of the light shielding lens C to prevent the displacement. In this case, as shown in the figure, the first fixture A1
Is locked at the intermediate position of the upper side L1 of the light blocking lens C,
The second fixture A2 is locked at a position below the outer side L2 of the light blocking lens C, that is, near the lower side L3.

As will be described later, it is important that the second fixture A2 acts so as to press the eyeglass body G by the elasticity of the transition body B when the light shield S is attached to the eyeglass body G. Therefore, the mounting position of the second fixing tool A2 is provided at a position where such acting force appropriately acts.
Since the first fixing tool A is provided with the lateral hole 5, the hook portion 22 at the tip of the bridging body B can be strongly pushed into the lateral hole 5 to elastically fix it. By thus elastically fixing both ends of the transition body B to the left and right light-shielding lenses C, the light-shielding tool S having a shape corresponding to the spectacle body G is completed.

Next, a procedure for attaching the above-mentioned light shield S to the spectacle body G will be described. FIG. 8 shows a case where the eyeglasses to be attached are half-rim type eyeglasses. To attach the light shield S to the eyeglass body G, the light shield S is gripped and the supporting portions 2 of the left and right first fixtures A1 are brought into contact with the upper side L1 of the rim of the eyeglass body G so as to be hooked (arrow 1). reference). By hooking in this way, the spectacles main body G is supported by the support portion 2
The bulging portion 6 and the base portion 1 are sandwiched.

Then, with the first fixture A1 as the starting point,
The light blocking lens C is pushed upward by utilizing the elasticity of the crossing body (see arrow 2). Then, the second fixture A2 is brought into contact with a predetermined position on the outer side L2 of the lens. afterwards,
When the hand is released, since the transition body B has elasticity, the light shield S tries to return to the original state. Due to the force of returning to the original state, the support portion 2 of the second fixture A2 acts so as to press the peripheral surface of the outer side L2 of the eyeglass body G. In this state, the shading device S is fixed by sandwiching the spectacle body G between the first fixing device A1 and the second fixing device A2.

FIG. 9 shows a state in which the light shield S is completely attached to the spectacle body G. It should be noted that also in the case of all-round rim type glasses other than the half rim type and two-point type spectacles that do not use a rim, the light-shielding device S can be easily performed by the procedure just described.
Can be attached to the eyeglasses main body G. As described above, since the light shield S of the present invention is attached to the spectacle body G, the fixture A is elastically fixed to the light shield S even if some force is applied to the light shield S. The force applied is relaxed so that no unreasonable force is generated in the light-shielding lens C, and the hole 32
Cracks are prevented.

Further, the claw portion 4 of the fixture A has a light-shielding lens C.
It is possible to reliably prevent the fixture A from being displaced along the peripheral surface of the light-shielding lens C by fitting in the notch 31 provided in the. Further, since the transition body B is elastically fixed to the fixture A, it can be easily removed, so that the light-shielding lens C can be easily replaced.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. . The protrusion 3A of the fixture A was divided into two, but it can be naturally adopted as long as it retains the elastic force even if it is divided into two or more. The base 1 of the fixture A includes a protrusion 3A and a claw 4 and is provided with a light-shielding lens C.
The shape can be modified as long as it can be appropriately elastically fixed. Further, the support portion 2 of the fixture A is a rim of eyeglasses,
Alternatively, any shape may be used as long as it can directly support the lens.
