Description

[Detailed Description of the Invention] The present invention relates to a hearing aid glasses adapter used when a hearing aid is integrally attached to the temple of glasses.

BACKGROUND ART Hitherto, an ear-hook type hearing aid as shown in FIG. 1 has been provided in order to reduce discomfort when using the hearing aid and to allow the user to hear sounds that approximate actual sounds.

This hearing aid 1 has a curved shape that follows the outer diameter of the ear as a whole, and a conduit 2 to which an ear-fitting body is connected is attached to the horn portion at the tapered tip, and the curved inner surface 3 of the hearing aid 1 and the conduit 2 and is configured to be used by hanging it on the ear.

Hearing aids constructed in this way are small and can fit closely into the ear, so there is no discomfort when using them, and they can hear sounds that are extremely close to actual sounds, making them extremely convenient for people with hearing disabilities. be.

However, for those who require glasses, the ear hooks provided at the tips of the temples of the glasses get in the way, making it impossible to use the above-mentioned ear hook type hearing aids.

Therefore, in order to make ear-hook type hearing aids available to people who require glasses, an adapter has been proposed that allows a hearing aid to be attached to the ear-hook part of the glasses.

However, with conventional adapters, it is not possible to adjust the position of the hearing aid on the temple of the glasses, or the adjustment is difficult.

In particular, the temples of glasses require minute adjustments to adjust the position of the glasses, but this adjustment cannot be made with conventional glasses, which causes discomfort when wearing hearing aids. I can't avoid it.

Therefore, the present invention solves the above-mentioned problems of conventional devices, and makes it possible to finely adjust the positional relationship between glasses and hearing aids, thereby eliminating discomfort during use. The present invention aims to provide a glasses adapter for hearing aids.

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

FIG. 2 shows a glasses adapter 11 for assistive devices according to the present invention,
This is a side cross-sectional view showing the arrangement relationship between the ear hook 12 and the temples 13 of glasses, which are connected via the adapter 11.

The hearing aid glasses adapter 11 according to the present invention is provided with a connecting portion 16 to which the ear cover fitting body is connected via a flexible connecting tube, protruding from a midway portion of the adapter body 17. L communicating with the connecting portion 16
A conduit portion 18 bent into a letter shape is bored through the adapter body 17.

A hearing aid fitting part 20 is provided at the end of the conduit part 18, into which a horn part 19 provided at the tapered tip of the hearing aid 12 is screwed.

That is, the horn part 19 is formed with a male threaded part 19a, and the hearing aid fitting part 20 is formed with a female threaded part 20a, so that the hearing aid 12 can be attached by relatively screwing the two together. ing.

Further, from the side opposite to the side where the hearing aid fitting part 20 of the adapter main body 17 is provided, the end part 21 of the temple of the glasses 13 is
A temple fitting portion 22 into which the screws enter and are screwed together is provided.

That is, the end 21 of the temple 13 of the glasses has a male thread 2.
1 a is engraved, while the temple fitting part 22 has a female threaded part 2.
2a is engraved, and the end 21 of the temple 13 is configured to enter and screw together from the side opposite to the mounting direction of the hearing aid 12.

The conduit portion 18 and the temple fitting portion 22 are connected to the adapter body 1.
The hearing aid glasses adapter 11 is provided so as to be located substantially coaxially within the hearing aid glasses adapter 7, and is formed so as to avoid becoming wide and large as the hearing aid glasses adapter 11.

If the adapter 11 can be formed in this way, the hearing aid 1
2, it becomes easy to design the ear hook part provided on the temple of the glasses on the side to which it is not attached, and it becomes easy to provide a product that eliminates discomfort during use.

The proximal end of the hearing aid fitting part 20 has a large diameter part 23 so that the horn part 19 is loosely fitted therein.
Together with the small diameter shaft portion 24 on the base end side, the horn portion 1
After 9 is screwed into the hearing aid fitting part 20, the hearing aid 12 becomes rotatable relative to the hearing aid glasses adapter 11.

When the hearing aid glasses adapter 11 configured as described above is used, the hearing aid 12 is attached to the glasses 25 through the adapter 11 with the curved inner surface 3 facing toward the front of the glasses 25, as shown in FIG. It is attached to the end of the temple 13 as if forming an ear hook part of the temple 13.

The attachment position of the glasses 25 of the hearing aid 12 to the temple 13 can be freely selected by adjusting the relative fitting amount between the temple 13 and the temple fitting portion 22 of the adapter body 17.

That is, by adjusting the above-mentioned fitting amount, the length L of the temple 13 including the hearing aid 12 as shown in FIG. 4 can be freely selected, so that the length L is suitable for each user. This can eliminate discomfort during use.

Furthermore, once the hearing aid 12 attached to the hearing aid glasses adapter 11 is completely screwed together, it can rotate freely relative to the adapter 11, so the amount of fitting between the temple 13 and the adapter 11 can be adjusted by rotational operation. Even if the glasses 25 are attached, the direction of attachment to the glasses 25 does not change.

Further, since the temple 13 is fitted into the hearing aid glasses adapter 11 with a screw engagement, the amount of fitting can be reliably adjusted, and fine adjustments can also be made.

In particular, if the pitch of each threaded portion 21a, 22a of the end portion 21 of the temple 13 and the threaded portion 22a of the temple fitting portion 22 is made minute, the adjustment can be made more finely.

Furthermore, in order to securely attach the temple 13 to the hearing aid glasses adapter 11, an insertion hole 27 for a fixing screw 26 is provided perpendicular to the temple fitting portion 22 of the adapter body 17, and the fixing screw 26 is held to secure the temple 13. If the end portion 21 is fixed as shown in FIG. 5, the fitting position of the temple 13 to the hearing aid glasses adapter 11 can be maintained constant, and the mounting position of the hearing aid 1 can be maintained constant.

In order to increase the amount of fitting of the temple 13 into the hearing aid glasses adapter 11, the temple fitting portion 22 is made to communicate over the entire length of the adapter body 17 as shown in FIG. As mentioned above, according to the present invention, all the fitting parts are in a screw-fitting relationship, so that the temple of the glasses and the hearing aid can be attached with fine adjustment of the positional relationship. Hearing aids that match the user's personality can not only be installed in good condition, but also easy to put on and take off, and the position after adjustment can always be kept constant, making it extremely convenient to use.
