Description

  The present invention relates to sunglasses with a presbyopia lens in which a presbyopia lens is provided on a part of a light-shielding lens (including a polarizing lens).

  Conventionally, as this type of sunglasses with a lens for presbyopia, glasses having a compound lens for glasses described in Utility Model Registration No. 3445534 (Patent Document 1) are known (see FIG. 3 of the publication). .

  The eyeglasses shown in FIG. 3 of Patent Document 1 include a temple and a lens frame fitted with a lens, and the lens has an opening in a lens body as a sunglasses lens or a polarizing lens. It is the structure which fitted the lens with a degree to. In the fitted state, as shown in FIG. 2 of the publication, an opening is formed in the lower portion of the lens body, and a prescription lens is fitted into the opening. In this case, a fitting groove is provided along the outer peripheral surface of the prescription lens, and the inner peripheral surface of the opening is fitted into the opening in a state of being in close contact with the groove bottom of the fitting groove. Therefore, the prescription lens protrudes outward from the surface of the lens body.

  According to the spectacles of Patent Document 1, a single spectacle can freely select a function as a polarizing lens or sunglasses by a lens body and a function as a near spectacle, reading glasses, or farsighted spectacle by a prescription lens. There is an advantage that can be used.

Utility Model Registration No. 3445534

  However, in the spectacles of Patent Document 1, since the prescription lens protrudes outward from the surface of the lens body, a step is generated between the outer peripheral surface of the prescription lens and the inner peripheral surface of the lens body. There are drawbacks such as dust adhering to the stepped portion and being easily soiled, and unsightly in appearance.

  The present invention has been devised to solve the above-mentioned conventional problems, and prevents the adhesion of dust by eliminating the step portion between the light-shielding lens (including the polarizing lens) and the lens for reading glasses. Another object is to provide sunglasses with a lens for presbyopia that is not unsightly.

  In order to achieve the above object, sunglasses with a lens for presbyopia according to claim 1 of the present invention are sunglasses with a lens for presbyopia comprising a temple, a lens frame fitted with the lens, and a nose pad, The lens is composed of a light-shielding lens (including a polarizing lens) mirror-coated with polycarbonate and a presbyopia lens formed on a part of the lower part of the back surface of the light-shielding lens, and the light-shielding lens and the presbyopia lens are integrally formed. It is characterized by.

  The sunglasses with a presbyopia lens according to claim 2 is the lens frame fitted with the lens according to claim 1, which is substantially T-shaped when viewed from the front, and the back surface of the T-shaped portion is bifurcated. And a leaf spring is provided in a space formed between the inward protruding portions, and a rear end portion of the bifurcated inward protruding portion is connected to the temple. The lens is pivotably attached to a recess at the center of the front frame connected through a hinge so that the lens can be flipped up.

  According to the sunglasses with a presbyopia lens according to claim 1 of the present invention, since the light-shielding lens (polarizing lens) is made of polycarbonate, it has excellent transparency and impact resistance and is mirror-coated. Therefore, by appropriately using a reflective color, not only can it function as sunshade sunglasses, but there is an advantage that fashionability is improved and it cannot be seen by others. In outdoor sports, fishing, horticultural work, etc., it not only functions as sunshade sunglasses but also has excellent fashionability and functions as protective glasses.

  Furthermore, since a prescription lens which is a presbyopia lens is formed in a part of the lower part of the back surface of the light shielding lens, for example, when the sunglasses function using the light shielding lens, the presbyopia is necessary. The function as reading glasses can be used by using a working lens. The reverse usage is also possible.

  Furthermore, the presbyopia lens is formed on the back surface of the light-shielding lens, and the light-shielding lens and the presbyopia lens are integrally formed to eliminate the stepped portion between the two lenses. Adhesion can be prevented and the appearance is not unsightly.

  According to the sunglasses with a lens for presbyopia of claim 2, in addition to the effect of claim 1, there are the following effects. That is, since the substantially T-shaped lens frame fitted with the lens is configured to be rotatable (raised) to the front frame, the lens frame (that is, the lens) is attached to the front frame and suspended. Therefore, it can be used as sunglasses or as reading glasses as necessary.

  In addition, in the case of claim 2, the lens frame (that is, the lens) is lifted up with the front frame as a pivot, and the object is moved with the naked eye without using the lens. I can see it. As a result, the glasses are particularly suitable for work such as horticulture or do-it-yourself.

  Furthermore, the lens of claim 2 is fitted to the lens frame, and the rear end portion of the bifurcated inward projection formed on the back surface of the substantially T-shaped lens frame is a central portion of the front frame. Since the lens (lens frame) can be pivoted up and down freely, there is an advantage that the structure is simple and the assembly can be simplified. .

  The lens frame 60 of the second embodiment has a separate and independent configuration from the front frame 70 connected to the front of the temples 20 and 21 via hinges 22 and 23. That is, the lens frame 60 is substantially T-shaped when viewed from the front, and has bifurcated inward projections 62, 62 extending on the back surface of the T-shaped portion 61. A leaf spring 64 is provided in the space 63 formed between the protrusions 62 and 62. The rear end portions of the bifurcated inward projections 62 and 62 are pivotally attached to a recess 71 formed in the central portion of the front frame 70 so as to be able to turn.

The pivoting structure of the inward projections 62, 62 will be described in detail. As shown in FIG. 9, a partition wall 72 is erected at the center of the recess 71 of the front frame 70. Horizontal axes 73 are provided on the left and right.
On the other hand, fitting holes 62a and 62a for fitting the horizontal shafts 73 provided on the left and right of the partition wall 72 are formed in the rear portions of the inwardly protruding portions 62 and 62 of the lens frame 60 (see FIG. 9). ).

  The lens frame 60 (with the lenses 11 and 12) is assembled by fitting the horizontal shafts 73 and 73 of the front frame 70 into the fitting holes 62a and 62a of the inward projections 62 and 62, respectively. By removing the fitting holes 62a and 62a from the horizontal shafts 73 and 73, the lens frame 60 with the lenses 11 and 12 can be removed.

Since it is configured as described above, as described in [0013], the lens frame 60 (that is, the lenses 11 and 12) is suspended from the front frame 70 to be used as sunglasses or as reading glasses. (See FIGS. 7 to 11).
Also, as shown in FIGS. 12 to 14, the lens frame 60 (that is, the lenses 11 and 12) is lifted upward with the horizontal shaft 73 of the front frame 70 as a pivotal fulcrum, and is then flipped up. , 12 can be used to see the object with the naked eye (see [0014], [0015]). The leaf spring 64 holds the spring-up state. When the lens frame 60 is pushed down against the elastic force of the leaf spring 64 in the flip-up state, the lens frame 60 (that is, the lenses 11 and 12) is moved to the front frame 70 as shown in FIGS. Drooping forward. Thus, the undulating state of the lens frame 60 (lenses 11 and 12) is reliably held by the click motion action of the leaf spring 64.
