Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to interchangeable lens type spectacles that can be replaced with any lens according to the intended use.

[Conventional technology]

In spectacles, especially sunglasses used for leisure purposes, it is desirable to change the color density according to the weather conditions. Therefore, sunglasses using a polarizing lens whose color density changes depending on the strength of the sunlight are also provided. However, since such sunglasses are of a type in which the temples are worn on the ears, it is possible for people who are familiar with eyeglasses to correct their eyesight, etc. , Temple is squeezing both sides of the face, making it cramped and uncomfortable. In addition, when wearing glasses, it is inconvenient to wear sunglasses.

[Problems to be solved by the device]

Therefore, as disclosed in Japanese Utility Model Application Laid-Open No. 63-144616, there is provided sunglasses in which an adapter that can be mounted on the tip of the eaves of a hat or sun visor is provided and a lens body is attached to this adapter. Since this sunglasses does not require the temples to be worn on the user's ears, there is no pressure when wearing the sunglasses, and there is an advantage that even people who do not normally wear glasses can use the sunglasses without feeling any pressure or discomfort. .

However, since the spectacle lens is fixed to the adapter, when changing the color depending on the surrounding brightness,
The whole must be replaced, and carrying multiple eyeglasses with adapters is not only costly and bulky, but can also damage the spectacle lens with the adapter.

This invention has been made in consideration of the above-mentioned conventional circumstances, and the purpose thereof is to make it possible to replace the lens by allowing the lens to be freely inserted into the lens frame and to be detachable from the eaves such as a hat. An object of the present invention is to provide interchangeable lens type eyeglasses having an attachment which is attached and can be compactly stored when not in use.

It is characterized in that 15 receiving portions 13 are formed.

[Operation] According to the above configuration, by inserting the lens 2 into the lens frame 1 from the through groove 7 of the upper frame 6, the lens 2 is fitted into the groove 5 formed in the side portion and the lower frames 3 and 4. Are held together. To replace it, hold the lens 2 with your fingers and hold it through the through groove 7
Just pull it out.

Further, in order to attach the eyeglasses to the eaves of the hat, the attachment 14 is moved from the stored state in FIG.
After rotating 90 degrees clockwise in the figure around the center, the entire body is rotated forward around the pivot point of the second sliding member 24 by the inserting member 15 to move the lens frame 1 as shown in FIG.
Set horizontally at the position above. Then, the eaves of the hat are inserted between the upper holding portion 18 and the lower holding portion 19. The position of the lens frame 1 with respect to the eye can be appropriately adjusted through the first and second sliding members 22 and 24.

〔Example〕

The present invention will be described below with reference to an embodiment shown in the drawings. A lens frame 1 made of a synthetic resin having a little flexibility is configured to accommodate a lens film 2 in which both eyes are integrally formed. Grooves 5 are formed on the inner peripheral surfaces of the partial frame 3 and the lower frame 4 so that the side portions and the lower end edges of the lens frame 1 are fitted. The upper frame 6 is formed with a through groove 7 that penetrates to the inner peripheral surface thereof.
A protrusion 8 for preventing the inserted lens film 2 from coming off is integrally formed at a substantially middle portion of the through groove 7. Since the lens frame 1 is somewhat flexible, when the lens film 2 is replaced, the protrusion 8 may be pushed and expanded.

At the center of the back surface of the upper frame 6, a supporting member 11 is provided.
It is rotatably attached by 12. This support member
11 has a receiving portion 13 having a substantially C-shaped cross section. An insertion member 15 of an attachment 14 to be attached to a hat, a visor of a sun visor or the like is inserted into the receiving portion 13.
The attachment 14 has a holding member 16 formed of a metal wire or the like that holds an eaves or the like, and an extension member 17 located below the holding member 16. The holding member 16 has an upper holding portion 18 bent in a substantially inverted V shape, and a lower holding portion 19 having straight portions which are attached to both ends of the upper holding portion 18 and which are located in parallel with each other. ing. A stopper 21 made of synthetic resin is attached to the end of the lower holding portion 19 located on the corner side of the upper holding portion 18. A first sliding member 22 made of synthetic resin or the like is slidably inserted in the straight portion of the lower holding portion 19. To the first sliding member 22, one end of an extension member 23 composed of two metal wires arranged in parallel is fixed. The extension member 23 is located below and parallel to the lower holding portion 19. A second sliding member 24 similar to the first sliding member 22 is slidably inserted into the extension member 23. The insertion member 15 described above is provided below the second sliding member 24. The insertion member 15 is bent in a substantially W shape, and the lower portion thereof is composed of a linear member configured to have elasticity in the outward direction. Both ends thereof are inserted into both side parts of the adapter 13 so as to be freely rotatable and held. A hook-shaped groove 25 for holding the insertion member 17 substantially vertically and horizontally is formed on both sides of the adapter. Extension member
A stopper 26 similar to the stopper 21 is attached to the other end of 23.

When the above-mentioned spectacles are attached to a hat or sunshade eaves (not shown), the support member 11 is rotated 90 degrees clockwise from the state shown in FIG. 1 with the support shaft 12 as a fulcrum, and then the insertion member 15 is moved to the first position. 2 Rotate from the sliding member 24 so that the attachment 14 is positioned horizontally above the upper frame 6. At this time, since the insertion member 15 engages with the vertical groove of the groove 25, the lens frame 1 does not rattle.

After setting the attachment 14 at the predetermined position in this way, the eaves are inserted between the upper and lower holding parts 18 and 19 of the holding member 16 so as to sandwich the eaves. If the eaves are short, the stopper 21 may be positioned above the stopper 26, and the position of the lens frame 1 may be adjusted by moving the second sliding member 24 on the extension member 23. Even when the second sliding member 24 is brought into contact with the first sliding member 22, when the lens frame does not reach the desired position, that is, when the eaves are long, the holding member 16 is further pulled out. Thereby, the lower holding part 19 of the holding member 16 is pulled out through the first sliding member 22 and can be extended until the stopper 21 comes into contact with the first sliding member 22. When the spectacles are attached to the eaves and the spectacles are to be removed, if the lens frame 1 is rotated upward, the insertion member 15 is fitted in the horizontal groove portion of the groove 25.
The lens frame 1 can be held horizontally on the lower surface of the eaves.

When the eyeglasses are removed from the eaves and carried, the holding member 16 is rotated at the insertion member 15 so that it is perpendicular to the lens frame 1, and then the holding member 16 is positioned horizontally on the back surface of the lens frame 1. By rotating the support shaft 12 from the support shaft 12 as described above, it is possible to make it compact as shown in FIG.

[Effect of device]

As described above, according to the present invention, the lens can be freely inserted into the lens frame, so that the lens can be converted into a desired lens according to the surrounding environment and brightness. If you prepare only one lens, you can purchase another lens when you want to use another lens, so you can enjoy various variations at low cost.

Further, since the eyeglasses are detachably attached to an eaves such as a hat or a sun visor via an attachment, even a person who does not normally use the eyeglasses can use the eyeglasses without feeling discomfort. Moreover, since the length of this attachment is adjustable, it can be used regardless of the length of the eaves, and when not in use, it can be compactly stored within the size of the lens frame, making it portable. It is convenient.
