Description

The present invention relates to pollen-preventing eyeglasses for preventing pollen and dust from entering the eyes.

Among spectacles with a hood that prevent pollen and dust from entering the eyes, there are known spectacles in which the hood portion can be attached and detached depending on the season and the place so that the spectacles can also be used as normal spectacles.

Although these glasses are easy to put on and take off, it is required that the hood part does not come off or shift, and the applicant of the present invention has been able to put on and take off the inner frame having the hood part, and the attached inner frame may come off. We have applied for a patent for the technology of difficult glasses (see Patent Document 1).

However, with this technique, there are many locking portions between the front frame and the inner frame, and it takes time to attach and detach. In addition, in the vicinity of the bending edge, it is necessary to adopt a structure that affects the appearance, such as inserting a protrusion into the through hole or gripping the bending edge so that the inner frame does not come off easily. There was a problem.

Japanese Patent No. 5690907

The present invention has been made in view of the above problems, and its purpose is not only to prevent pollen and dust from getting into the eyes, but also to determine the presence or absence of pollen, the brightness, etc. Accordingly, it is an object of the present invention to provide pollen prevention spectacles in which the inner frame can be easily attached and detached and the sunglasses can be switched to sunglasses.

The means adopted by the present inventor to solve the above problems are as follows.

That is, according to the present invention, a rim portion that holds a lens, a bridge portion that connects a pair of rim portions, bending tips formed at both left and right ends of the rim portion, and a nose pad portion that is integrally formed with the rim portion. A front frame provided with an inner rim portion that is removable from the rear of the front frame and that corresponds to the shape of the rim portion, an inner bridge portion that corresponds to the shape of the bridge portion, and upper and lower edges of the inner rim portion. The inner frame made of a soft resin having a light-transmitting property and having a hood portion formed on the side portion on the bending edge side corresponds to the inner rim portion on the inner surface side of the base in the nose pad. The fitting groove of the above shape is provided up and down, the inner rim part can be inserted into the fitting groove, and the hood part of the side part on the bending edge side is attached to and detached from the press-fitting groove part formed on the inner surface side of the bending edge part. It is characterized by the provision of possible projections.

Further, it is preferable that the vertical width of the protrusion is larger than the vertical width of the press-fitting groove.

Further, in the sub-frame that is attachable to and detachable from the front frame with the light-shielding lens attached, the first magnets attached to the back surfaces of the left and right end portions of the sub-rim portion holding the light-shielding lens and the pair of sub-rim portions are provided. A hook portion having an L-shaped cross section that protrudes rearward from the connecting sub-bridge portion and is bent downward, the hook portion engages with the bridge portion, and the first magnet is provided at both left and right ends of the rim portion. The sub-frame can be attached to the front frame by magnetically attaching to the second magnets attached to the back side.

In the present invention, the inner frame formed with the hood portion can prevent dust such as pollen from entering the eyes when it is attached, and can be used as ordinary glasses by removing it when necessary.

Here, the inner rim portion can be inserted into the fitting groove provided on the inner surface side of the base portion of the nose pad, and the hood portion of the side surface portion on the bending side is formed on the inner surface side of the bending portion. Since the press-fitting groove portion is provided with the detachable projection portion, the inner frame can be attached to the front frame by a simple operation of engaging at two right and left portions.

Also, by making the vertical width of the protrusions larger than the vertical width of the press-fitting groove portions, appropriate friction is generated, and the hood is in close contact with the front frame, and at the same time, it is difficult to shift in the vertical and horizontal directions. There is also an effect.

Furthermore, by configuring the sub-frame with the light-shielding lens attached to the hook portion of the sub-bridge portion and the magnets on the left and right ends of the sub-rim portion, the sub-frame can be attached by a simple operation of lowering the sub-frame from above the front frame. You can As a result, not only can the inner frame be attached and detached depending on the presence or absence of pollen or the like, but also sunglasses can be used depending on the surrounding brightness conditions, and one eyeglass can be switched to a comfortable state.

"Example 1"
The first embodiment of the present invention will be described with reference to FIGS. The present invention is not limited to the embodiments shown in these accompanying drawings.

In this embodiment, as shown in FIG. 1, the front frame 2 and the temples 4 and 4 are hingedly connected, and the inner frame 3 is mounted behind the front frame 2.

The inner frame 3 is attachable to and detachable from the front frame 2, and can be used as normal eyeglasses when not worn, and when worn, it functions as pollen prevention eyeglasses.

The front frame 2 includes rim portions 2a and 2a to which the lenses 2f and 2f are attached, a bridge portion 2b that connects the rim portions 2a and 2a, and bending bending portions 2c and 2c formed at the left and right ends of the rim portions 2a and 2a. The nose pad portions 2d and 2d are integrally formed to project from the portions of the rim portions 2a and 2a near the bridge portion 2b.

In addition, press-fitting groove portions 2e, 2e having a U-shaped cross section are formed on the inner surface side of the bending portions 2c, 2c. The press-fitting groove portions 2e, 2e are open only on the surface of the bending ridges 2c, 2c on the side of the temples 4 and 4, and the hinges attached to the temples 4 and 4 are included therein so that they can be connected by hinges.

Here, in the present embodiment, the rim portions 2a and 2a, the bridge portion 2b, and the bending ridge portions 2c and 2c are formed as an integral plastic frame, but they may be formed separately and connected to each other.

On the other hand, as shown in FIG. 2, fitting grooves 2g and 2g are formed at the bases of the nose pads 2d and 2d, and the engaging portions 3d and 3d of the inner frame 3 are fitted into the fitting grooves 2g and 2g. I am able to insert it. As a result, even if the inner frame 3 is pulled rearward, the inner rim portions 3a and 3a inserted into the fitting grooves 2g and 2g of the nose pads 2d and 2d of the front frame 2 serve to prevent the displacement. The inner frame 3 can be prevented from coming off (described later).

As shown in FIG. 3, the inner frame 3 mounted on the front frame 2 includes inner rim portions 3a and 3a corresponding to the shapes of the rim portions 2a and 2a, an inner bridge portion 3b corresponding to the shape of the bridge portion 2b, and an inner rim. The shape is provided with the hood portions 3c and 3c formed on the upper and lower edges of the portions 3a and 3a and the side surface portions on the bending bending portions 2c and 2c side.

Here, a part of the inner rim portion 3a, 3a on the side of the nose pad 2d, 2d is an engaging portion 3d, 3d in which the hood portion 3c, 3c is not formed, and can be inserted into the fitting groove 2g, 2g. In order to do so, it has a width that matches the fitting grooves 2g, 2g.

Further, the hood portions 3c, 3c on the side surface portion on the bending edge 2c, 2c side are provided with protrusions 3e, 3e. The protrusions 3e and 3e are protrusions having rounded corners and a rectangular cross section, and protrude in the left-right direction of the face when wearing glasses.

The inner frame 2 in the present embodiment is made of a light-transmitting polyamide so as not to obstruct the field of view, but a material other than polyamide may be used as long as it is light-transmitting and has excellent elasticity. You may use.

The temples 4 and 4 extend from the bending portions 2c and 2c, as shown in FIG. In the present embodiment, the temple 4 is made of polyamide with a metal core, but the material is not limited to polyamide as long as it is a material having elasticity.

Next, a method of mounting the inner frame 3 on the front frame 2 will be described. First, the fitting grooves 2g, 2g of the inner frame 3 and the engaging portions 3d, 3d are engaged.

Specifically, as shown in FIG. 4(a), the inner frame 3 is lowered from above the front frame 2, and the engaging portions 3d and 3d are inserted into the fitting grooves 2g and 2g. At this time, the protrusions 3e, 3e of the inner frame 3 interfere with the bending portions 2c, 2c. Therefore, while bending the inner frame 3 so as to be folded inward with the inner bridge portion 3b as a fulcrum, the fitting groove 2g Inserting the engaging parts 3d and 3d into 2g makes the work easier.

When the deformation is undone, as shown in FIG. 4(b), the engaging portions 3d and 3d are engaged with the fitting grooves 2g and 2g, so that the inner bridge portion is hard to be displaced in the front-rear direction and the left-right direction. Become.

Next, as shown in FIG. 5(a), the protrusions 3e and 3e provided on the hood portions 3c and 3c are press-fitted into the press-fitting groove portions 2e and 2e provided on the bending tips 2c and 2c. The vertical width of the protrusions 3e, 3e is formed to be slightly larger than the vertical width of the press-fitting groove portions 2e, 2e.

By forming in this way, since the protrusions 3e and 3e are elastically deformed and press-fitted into the press-fitting groove portions 2e and 2e to generate an appropriate frictional force, the hood portions 3c and 3c are less likely to shift in the vertical and horizontal directions. Since the inner frame 3 is made of elastic polyamide, it can be easily press-fitted when mounted.

Note that the inner frame 3 can be removed in the reverse order of the above-described mounting method. First, the protrusions 3e and 3e are removed from the press-fitting groove portions 2e and 2e. The protrusions 3e, 3e can be easily removed by pulling the hoods 3c, 3c inward.

Next, the inner frame 3 is removed by lifting it from the front frame 2. At this time, if the inner frame 3 is lifted while being bent so as to be folded inward with the inner bridge portion 3b as a fulcrum, it is easy to work.
