Abstract

PURPOSE:To provide spectacles which can be worn as ordinary spectacles during normal time and can be worn in a stable state by drawing bands from the ear part of spectacle temples and fastening securely the bands to the circumferential part of the head in the stage of motion that accompanies vigorous body action. CONSTITUTION:Bands 3 are respectively internally provided to temples 2 freely drawably and retractably in ear parts 21. The bands 3 are so constituted that the top ends of the drawn out bands can be freely attachably and detachably connected to each other in the suitable position in the circumferential part H of the wearer's head. If vigorous body motion is anticipated, the weaer draws out the bands 3 from the parts 21 and fastens the same to the circumferential part of the head. The dislodging of the spectacles by shock is thus prevented. If the engagements 5, 6 between the bands 3, 3 are released, the bands 3 are retracted and housed into the temples 2 by the spring back effect and therefore there is no possibility of having trouble in meeting with customers in daily life.

Description

[Detailed Description of the Invention] The present invention relates to eyeglasses with temple-retractable head hands, and the purpose thereof is to be able to be worn as normal eyeglasses during normal times when only doing quiet routing work, and to be worn as normal eyeglasses during sports play. To provide a new type of eyeglasses that can be worn in a stable state like goggles by pulling out a band from the ear hook part of the eyeglass temple and firmly tightening it around the surrounding area during exercise that involves strenuous physical movements. .

As shown in Fig. 7, glasses with band B connected to the ear hooks of temples 2 and 2 of the glasses and tightened around the wearer's circumference like goggles can be used as sports glasses. It is conventionally well known (see Japanese Patent Publication No. 15910/1983). However, when using this product in daily life, if Band B is not removed, it will give other people a strange feeling, so it is not desirable for personal taste. It was said that if it was removed, it would be lost or misplaced, rendering it useless when needed, and being troublesome and inconvenient to store.

A common complaint about this type of sports glasses is that it takes time and effort to connect the hands and the temples of the glasses. This point.

Regarding the sports glasses shown in Figure 7 above.

Although these drawbacks have been alleviated.

Even so, I took off my glasses and put my hand B on the moon part of the temple.
It was necessary to connect the two, and the customer's satisfaction had not yet been achieved.

The present invention was made in view of the above-mentioned drawbacks of the conventional headband fastening type glasses.The present invention will be explained based on the illustrated embodiment. Each of the provided temples 2 is provided with a band 3 inside the ear hook part 21 of both temples 2 so as to be able to be pulled out and retracted with a spring hack, and the tips of both bands 3 are formed into 5 and 6 that can be hooked together. 2. This invention relates to eyeglasses having temple-retractable head hands, which are characterized in that they are configured so that they can be connected to each other at appropriate positions on the wearer's circumference H.

To add a further note to the illustrated example, the present invention can be applied to both synthetic resin eyeglasses and metal frame eyeglasses, and in either case, the through hole 22 is formed along the axis of the temple. The band 3 is inserted into the through hole 22. Therefore, as the band 3, an elastic cord material with high elasticity, such as an elastic cord (for example, a rubber cord), is used. However, the entire band 3 is not required to be stretchable, and a stretchable elastic cord may be used only in a portion thereof.

An example of a structure in which the band 3 is inserted into the through hole 22 of the temple 2 is shown in FIG.

That is, the base end 23 side of the temple 2 is configured such that by removing the cover 25, a spring mounting part 22a formed with a slightly larger diameter than the through hole 22 in the other axis portion is exposed. A compression coil spring 4 is interposed in this spring mounting portion 22a.

The spring 4 used in this embodiment preferably has a low spring coefficient, and is preferably compressed before the band 3 is expanded. The band 3 passes through the spring 4 and exits toward the temple base end 23, where it is hooked onto the spring 4. Therefore, when the band 3 is pulled from the ear hook 21 side of the temple 2, the coil spring 4 first contracts, and then the band 3 begins to expand. Furthermore, as shown in Fig. 6,
Of course, it is also possible to incorporate an automatic take-up reel 24 into the temple 2 and connect the band 3 to this automatic take-up reel 24.

As mentioned above, the other end of the band 3, which is housed inside the temple 2, is connected to the ear hook part 21 in the example shown in FIG.

Connected thereto are hook-type engaging members 5 and 6 that can be hooked onto each other. The engaging members 5 and 6 are removably fitted to the ends of the ear hooks 21 of the temples, and their appearance when fitted is a part of the temple ear hooks as they are continuously integrated into the shape of the temple ear hooks. It has become a fusion of.

Specific examples of the present invention are generally as described above.

The present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. In addition to the drawings and drawings shown in Figure 6,
It is possible to adopt a means to enable the retraction operation,
Furthermore, as a means for engaging the bands 3 around the wearer's head, it is also possible to employ a well-known engaging member such as a bell-bent fastener (trade name: 1 Velcro fastener).

As explained above, in the glasses to which the present invention is applied, the hands 3 are housed in each of the temples 2 in the ear hook portion 21 so as to be freely drawn out and retracted.

Moreover, the tip of the band 3 that has been pulled out is located around the wearer's head circumference H.
Since the glasses are configured so that they can be detachably connected to each other at appropriate positions, when intense physical exercise is expected, the band 3 can be pulled out from the ear hook 21 and tightened around the head to prevent the glasses from falling off due to shock. This can be prevented, and if the bands 3 and 3 are disengaged from each other, the band 3 will be retracted into the temple 2 by the spring hack action.

Even in daily life, there is no possibility of this becoming a hindrance to customer service.

As described above, according to the present invention, the conventional
Not only has the problem of storage and mounting problems that were considered difficult with mirrors been solved, but it also has functions for both sports and everyday routine work. It has great benefits for those who wear IR mirrors, such as being able to do both.
