Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY The present invention relates to spectacles for full-face masks, in which when a spectacle user wears a full-face mask, the function of the mask is not impaired and the spectacles can be easily adjusted.

2. Description of the Related Art If a spectacle user wears a full-face mask while wearing spectacles, leakage occurs from the vine portion of the spectacles, which is unacceptable for safety.
It has been found that not only does the work efficiency decrease, but there are many inconveniences in maintaining work safety. For this reason, various measures have been devised, such as dedicating special glasses to the inside of the entire mask, but there are many things that can not adjust the position of the lens of the glasses and the eyeball, and even if it is bent For these reasons, the conventional device is not suitable for practical use, for example, the optical axes of the glasses and the lens do not match or the focal lengths do not match.

Problem to be solved by the invention As described in the related art, it is good to attach dedicated glasses inside the entire mask, and the lens of the glasses,
There has been a problem that the relative position with respect to the eyeball cannot be adjusted, the optical axes of the glasses and the lens do not match, and the focal length does not match. Therefore, the present invention solves the problems of the prior art by providing a function of adjusting the vertical position, depth, and inclination of the spectacle lens so that the eye axis, the optical axis of the lens, and the focal length can be adjusted. It is an object of the present invention to provide spectacles for a full-face mask that can perform the above.

Means for Solving the Problems In order to achieve the above object, a support for supporting the vine of eyeglasses is attached to a predetermined position on the inner surface on both sides of the mask main body, and a device for adjusting the inclination angle of the lens of the eyeglasses is mounted on this support. The rear end of the support that supports the vine with the vine horizontally and adjusts the vine so that it can be moved forward and backward can be connected so that it can be inserted and removed and the height can be adjusted.

Function Since a plurality of holes are arranged in a row on the support base of the eyeglass vine which is glued to both sides of the face of the entire mask with an adhesive as shown in FIG. The vertical position of the lens can be adjusted by selecting and inserting the insertion leg provided on the support of the vine. The depth of the lens is adjusted by adjusting the depth at which the vine is then inserted into the hole in the support. When the lever 6 is loosened, the inclination of the lens can be adjusted. By adjusting the above three points, it is possible to adjust the eye axis, the optical axis of the lens, and the focal length.

Example As shown in FIG.
As shown in FIG. 2, the support 2 includes a support 4 for the vine 5 and a lever 6 for adjusting the inclination of the lens unit 7. The support 2 is bonded to both the right and left face parts of the mask body. The support 2 is made of the same material to improve the adhesiveness to the entire mask. Next, as shown in FIG. 3, the support 4 is provided with a deep hole 9 in the longitudinal direction, into which the rear end of the vine is inserted so that the position of the lens 7 can be adjusted by the insertion depth. Further, at the rear end of the support 4, there is provided an insertion leg 8 which is inserted and connected to the insertion holes arranged in the support base 2, and the support 4 is connected to the support 2 by inserting this. ing. The lever 6 can adjust the inclination of the lens 7 by the adjustment.

Effect of the Invention Since the present invention is configured as described above, before mounting the full-face mask on the face, the support 4 for the vine 5 of the spectacles is required.
If the appropriate insertion hole 8 is selected from a plurality of holes 10 provided on the support base 2 of the vine mounted on the face-facing portion of the mask body and the connection legs 8 are provided and connected to the eyeglasses, the eyeglasses can be used. Vines, of course,
Since the support base and the like are all stored inside the mask body, there is no danger of leakage when the mask is worn, and when the mask body is mounted, the focusing operation of the lens is adjusted by a few degrees. The lens position can be adjusted easily and comfortably, so if it is adjusted once, it will not be troublesome to adjust it each time the mask face is attached or detached, which impairs the safety of eyeglass wearers Therefore, it is possible to comfortably engage in the work and to improve the work efficiency.
