[0001]

[Industrial applications]

 The present invention relates to front spectacles for use in sunglasses, etc., which are attached to the front front of corrective spectacles and the like.

[0002]

[Prior art]

 If the sun is too dazzling while driving a car, it is safer to use sunglasses to reduce the amount of light that enters your eyes so that you can see ahead easily. However, for those who originally use corrective glasses, the corrective glasses interfere and the sunglasses cannot be worn. On the other hand, it is not possible to remove corrective glasses and wear only sunglasses. On the other hand, there has been an attempt to reduce the amount of transmitted light of a spectacle lens for correcting vision to make the function of the correcting spectacle and the function of the sunglasses both combined. However, there is a problem that such dual-use spectacles alone hinder daily life, eventually requiring two types of dual-use spectacles and ordinary corrective spectacles, which is expensive.

[0003] Therefore, conventionally, sunglasses have been designed so that they can be detachably used over ordinary straight spectacles so that both the use as ordinary straight spectacles and the combined use as sunglasses can be achieved. was there. This detachable sunglasses is commonly referred to as front spectacles, and is equipped with a fitting on the front part including the sunglasses lens, and is removably held on the corrective glasses by this fitting. However, these apron glasses cannot be used unless the type of attachment is originally compatible with the corrective eyeglasses.In addition, if the shape of the sunglasses lens is not compatible with the shape of the corrective eyeglasses, both lenses will be It had the drawback that it didn't overlap well and was awkward or that the lenses scratched each other. However, if one could prepare various types of apron glasses to suit various types of corrective glasses, this drawback should not be a problem. However, not everyone who purchases correct eyeglasses buys the appropriate front eyeglasses, so if the front eyeglasses are prepared for all types of eyeglasses, they will be left as an unnecessary inventory. In reality, however, it was only possible to prepare apron glasses for a small number of corrective glasses, which narrowed the range of choices for purchasers.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned problems in conventional aerial spectacles. Therefore, it is a technical problem to realize general-purpose aerial spectacles that can be used for any spectacles. Is.

[0005]

[Means for Solving the Problems]

 The means adopted in the present invention for solving the above problems will be described below. That is, it forms a groove in a pair of left and right lens peripheral portions, connects a lens stopper with a bridge, and abuts the lens stopper on each peripheral required portion of each lens and fits in the groove. While winding the band around the lens periphery, connect both ends of this band to the lens stopper, sew a hook to the band and hold it on the lens periphery, the hook is caught on the front edge of the ordinary glasses, This means that the whole body can be attached to the front of ordinary glasses.

Here, ordinary glasses refer to corrective glasses or the like that are worn on the face and are regularly used. In order to adapt the apron glasses to a wide variety of ordinary glasses, it is effective that the lens shape of the apron glasses can be changed according to the ordinary glasses, and that the mounting tool has versatility. I thought there was. Therefore, first of all, the lens of the front spectacles was fixed by winding it with a band. By adopting this configuration, it becomes possible to change the shape of the lens. In practice, it is sufficient to cut and mount an arbitrary lens in the shape of a lens from a circular lens material in accordance with the intended ordinary eyeglass lens. As a result, lens incompatibility can be prevented. Further, the attachment device for the front spectacles adopted in this means is a method of hooking the hooks on the ordinary spectacles. For this reason, the ordinary glasses that can be attached do not require a special configuration, and can be attached to and removed from ordinary glasses that have a normal structure.

Further, if, for example, two holes are provided side by side in this hook and the hook is fixed by passing a band through the hole, the installation position of the hook can be set on the lens periphery of the front spectacles. You will be able to move freely. As a result, it becomes possible to move the hook to an appropriate position where various parts of ordinary glasses are not hindered, and the versatility is further enhanced.

If the hooks are arranged at two positions above and below the outer peripheral edge of the lens and the bridge is elastically bendable, the front spectacles can be easily attached and detached. In other words, you can bend the bridge with your hand, bring it to the front front of ordinary glasses, and simply release it to hook the hook on the front edge of ordinary glasses. At this time, in order for the hook to perform its function, the left and right lenses must be installed opposite to each other. In addition, the distance between the left and right lens stops must be kept constant in order to keep the hook facing distance constant.

Further, if the flexible bridge is configured to be expandable and contractable, the lens stop interval can be adjusted, and even if the lateral width of the ordinary glasses changes significantly, a single front-mounted You will be able to fit with your glasses. Note that such a bridge can be realized by a method of screwing the long holes of the two bridge pieces with long holes. In addition, an inverted U-shaped reinforcing material may be arranged in the vicinity of the connecting root portion of the lens stopper and the bridge so that the connecting portion with the lens stopper is not broken when the bridge is bent.

Further, when the hooks are arranged at the upper and lower portions of the peripheral portion of the lens outside, the attachment and detachment of the front loupe can be performed only by expanding and contracting the bridge.

[0011]

【Example】

 Hereinafter, the present invention will be described based on embodiments.

A long hole 11 a is formed in a flat metal wire having a predetermined length along the longitudinal direction to form a bridge piece 11. Prepare two such bridge pieces 11, 11, overlap the long holes 11a, 11a, insert screws 12, 12 into the long holes 11a, 11a, and fasten them with nuts 13, 13 to make the bridge pieces 11, 11 together. Connect to get Bridge 1. The entire length of the bridge 1 can be changed by loosening the nuts 13 and 13 and sliding the bridge pieces 11 and 11 to each other and tightening the nuts 13 and 13 again. The flat metal wire used for this bridge piece has a certain degree of spring property, so that the bridge 1 can be elastically bent.

Lens stoppers 2 are attached to both ends of the bridge 1. This attachment is achieved by bending the required area of the bridge tip in parallel with the lens stoppers 2 and 2 to make contact, and then brazing the contact portion. Further, in order to prevent the brazed portion from coming off when the bridge is bent, which will be described later, each lens stopper 2 is provided with an inverted U-shaped reinforcing member 22 for reinforcement. The reinforcing member 22 is brazed to the lens stopper 2 at both ends of the inverted U-shape with the portion closer to the center of the brazed portion of the bridge 1 being held inside the inverted U-shape to perform reinforcement. . The lens stopper 2.2 has two holes 21.21 ... at each end, and a band 5.5 is connected to the holes 21.21 ... to hold the sunglasses lenses 4.4. can do. At this time, the band 5 has both ends inserted into the holes 21, 21, ... Of the lens stopper 2 to be connected in a loop, and has two hooks 3, 3 sewn in the middle of the loop. The hook 3 is formed by projecting a hook-shaped hook member 31 on a chip-shaped base 32 having two holes. By inserting the band 5 into the hole of the base 32, the hook 5 is attached to the band 5. Sewn on. Then, when a groove is formed in the peripheral edge of the lens 4 and the lens 4 is held in the band 5 while the loop-shaped band 5 is fitted into the groove, the hook 3 is attached to the peripheral edge of the lens 4. The hooks 3 and 3 are installed so as to be arranged above and below the outer side of the lens 4, and in a state where the hook member 31 is brought out rearward and bent toward the lens center.

The front spectacles thus configured can be attached to the front of ordinary spectacles for correction which are supported by temples and pads. That is, after expanding and contracting the bridge of the front eyeglasses and fixing the front eyeglass with a predetermined width, the entire front eyeglass is bent so that the lower side of the lens opens while bending the bridge. When they are released in front of the eyeglasses, the bent front eyeglasses return to their original positions and their hooks are caught on the front edge of the ordinary eyeglasses. For this reason, the lens of the front glasses can be used by stacking it on the lens of ordinary glasses. It should be noted that the lenses of the front spectacles may be machined to match the lenses of the ordinary spectacles. In this way, even if the lens shape of ordinary glasses changes, it can be dealt with simply by exchanging the lens and band of the front glasses.

In addition, in the above-mentioned front spectacles, in order to improve the stability of the lens stopper and the lens, a ridge is provided on the lens contact surface of the lens stopper, and the ridge is formed in the groove of the lens peripheral portion. It is advisable to provide a groove for allowing the band to be depressed by a predetermined amount at the band connection portion of the lens stopper while fitting. At this time, use a thread that has a shape that protrudes by a predetermined amount when it is fitted into the groove on the peripheral edge of the lens, and only the protruding part is sunk into the groove for stopping the lens.

In addition, when the front spectacles are attached to the normal spectacles, the hooks may be hooked on the normal spectacles by expanding and contracting the bridge of the front spectacles to change the hook interval of the front spectacles. In this case, for example, a screw-type telescopic bridge with the same configuration as the above example can hold the length of the bridge by frictional force, but if a slightly strong force is applied, the screws and nuts will slide with the bridge pieces. Can be applied by tightening. Further, the force of the spring may urge the bridge in the direction of contraction, and the bridge may be expanded and contracted under the urging force.

[0017]

[Effect of device]

 As described above, since the front eyeglasses of the present invention use the band to stop the lens, it is possible to cope with changes in the shape of the lens, and it is possible to hook it on ordinary eyeglasses using hooks. , Ordinary glasses do not have to have a special structure for wearing front glasses. For this reason, one front spectacle can be adapted to a large number of ordinary spectacles, which is convenient.

Further, the hook is sewn to the band by simply adopting a simple structure in which two holes are arranged side by side in the hook, and the position where the hook is sewn to the band can be adjusted. By moving the hook to a position where it can be easily hooked on ordinary glasses, the effect of increasing the types of applicable ordinary glasses can be expected. Further, by disposing hooks at two positions above and below the outer peripheral edge of the lens, and by allowing the bridge to elastically bend or expand, it is possible to easily attach and detach the front spectacles. In addition, if the bridge is made extendable, the distance between lens stops can be adjusted, and the ability to respond to changes in the lateral width of ordinary glasses is increased.
