Abstract

PURPOSE:To enable the person wearing titled spectacles to view objects with ease by providing successively temples, via connecting members, on both sides of a front frame, making the temples foldable in superposition on the front frame and making the front frame tiltable in a developing direction with respect to the temples. CONSTITUTION:A connection piece A26 is inserted between both connection pieces 17 and 17 in a connection part 13 of spectacles for the aged, and both are connected by using a screw 33. A connection piece 29 is inserted between connection pieces 30 and 30, and both are connected by using a screw 35. Then a connection part J2 is pivotally fitted so as to make a temple 5 foldable in superposition with a front frame 2 and a connection part J1 can incline the frame 2 in a range of about 20 deg. to the inside and about 90 deg. to the outside relatively with the virtual line intersecting orthogonally with the temple 5. A frictional force is generated between a pressing piece 22 and the piece A26 by means of a coil spring 20 in this stage and the frame 2 is held at an optional angle of inclination. Thus the person wearing the spectacles corrects the sight by erecting approximately perpendicularly the frame 2 in the stage of seeing near objects such as in reading or writing and can directly see remote objects by tilting the front frame to an approximately straightly developed state inthe stage of viewing remote objects.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on making the inclination angle of the front frame variable, and the inclination angle can be appropriately adjusted so that the front frame comes into close contact with the face when worn. If this is not necessary (for example, when a person with presbyopia sees far away), the purpose can be easily achieved by tilting the front frame in the unfolding direction with respect to the temple, thereby saving the trouble of hanging and unhooking each time. It is related to glasses that are not only easy to use but also have excellent operability and aesthetic appearance.

First, the front frame of eyeglasses is normally inclined inward by about 8 degrees with respect to an imaginary line perpendicular to the temples.

Therefore, when wearing glasses, the nose seat may not fit tightly to the nose depending on the person, resulting in the glasses becoming unstable, and the center part of the lens not aligning properly with the eye, making it impossible to accurately correct vision. was there.

Second, reading glasses, for example, are necessary for near-field tasks such as reading and writing, but they are not required for viewing far away. In order to achieve these purposes without having to take off the glasses, flip-up glasses have been provided.

As shown in Fig. 8, the flip-up type glasses include a pair of left and right lens holding frames (a) connected at the center, a support frame (b) that supports the lens holding frames (a), and a support frame (b) that supports the lens holding frames (a). A temple (C) foldably hinged to the outer edge of the support frame (b)
said lens holding frame (a) has an edge (d) thereof;
), the support piece (θ) protrudes forward from the upper end of the support frame (b), and is attached to the tip of the support piece (θ) so that it is in a substantially horizontal state from a substantially hanging state (indicated by a dashed line in the same figure). , is formed into a spring-up iiJ' function. Further, a nose seat (f) is attached to the inner edge of the support frame (b), so that the lens holding frame (a) has a nose seat (f) attached to the front of the support frame (b) in its substantially hanging shape. They will be located at a relatively wide distance from each other.

Therefore, in such glasses, ■The raised lens holding frame (a) covers the space directly above the eyes like an eave, which obstructs the field of view when looking into the distance, and there are inconveniences such as sometimes having to look up. Ta.

■Also, as mentioned above, the lens holding frame (a) is the supporting frame (b).
Because the lens is located in front of the eye with a relatively wide distance from the support frame (b), the lens is too far away from the eye, making it difficult to determine the power of the lens, and sometimes resulting in an unnatural image that is larger than it actually is. In addition to detracting from the appearance of the glasses, the thickness of the glasses when folded is thicker than that of conventional glasses, so the glasses case must also be thicker. However, it also had some drawbacks that made it inconvenient for mobile phones.

■Moreover, attach the upper edge (d) of the lens holding frame (a) to the support frame (
*111. Since the lens is pivotally attached to lens holding frame (a), due to its structure, it is not possible to cleanly remove the eyebrows from the upper edge (d) of lens holding frame (a). < , there were restrictions on the design of the glasses.

The present invention provides eyeglasses (
The aim is to provide eyeglasses that allow users to see objects directly without having to take them off when necessary, without having to take them off.
One embodiment will be described below based on the drawings.

In Figs. 1 to 4, eyeglasses (1) of the present invention are formed as reading glasses, and temples (5) are connected to both sides of a front frame (2) via connecting members (3). The front frame (2) can be overlapped with the front frame (2) and folded, and the front frame (2) can be tilted relative to the temple (5).

The front frame (2) has a pair of left and right lens holding frames ((i) (6)
are integrally connected by a nose ring frame (7), and the lens holding frame (6) has eyebrows θI) attached to the two edges of the groove line θ0 that holds the lens (L), and A nose seat 0 is provided on the inner edge, and a connecting portion 0:0 is provided on the outer edge.

A coil spring (a) is interposed in the suppressing member at+
The storage device 1J' function is assumed to be 1J'. The pressing member 121) has a hole fl of the coil spring (e) that is slightly longer than the length of the coil spring handle at one end of the flat cylindrical pressing piece (c).
ls (20a) is provided with a protrusion (c) that can be moved by 11x, and when the coil spring wing is in a free state, the pressing piece protrudes from the spring insertion hole 05) and resists the force of the spring to close the spring insertion hole. (ff'i people will be included in 149.

The connecting portion 14 (3) has connecting pieces a, a(!7) (17) of the connecting portion 03 at the tip of the rectangular parallelepiped base (c).
A connecting piece A (c) that can be inserted between the connecting pieces and has a distal end surface (26S) formed as an arcuate surface protrudes. In addition, the connecting piece AK
9 has four through-holes θ that can be aligned with the screw holes (I (90Q) 1a. Also, below the rear end 1 of the inner bowl 9 of the base 9, there is a A connecting piece 13. [3 (Joo) that can sandwich the connecting piece 1] that protrudes from the connecting piece 1iij part is installed oppositely.In addition, the connecting piece 13, J (■ is), has a screw hole with the flower core aligned. 0υ (3υ is provided, and connecting piece b (2)
There are through holes (seconds) that can be aligned with both screw holes (31) (31).

Therefore, insert the connecting piece A of the connecting member (3) between the connecting pieces a and aθ of the connecting part θ→, and insert the connecting piece A of the connecting member (3) into the screw holes t and th.
Use the screw @ that screws into

, 4(1) can be worn with its front frame (2) erected approximately vertically to achieve its purpose without any problems.

On the other hand, when looking far away, etc., when there is no need to look through the lens, use the front frame (2) while holding the insula 0→ to your breath.
When the front frame (2) is tilted with respect to the temple (5) until it is in a substantially vertically unfolded state, the front frame (2) is lowered as shown by the dashed line, and the front frame (2) This allows you to see directly into the distance without any obstruction to your vision. In addition, when returning to work at home, the user only needs to raise the front frame (2) and return the glasses (1) to their original state.

Figures 6 and 7 show a rectangular parallelepiped-shaped connecting part (
The front frame (2) is pivoted about the pivot point, and the tip of the connecting member () η formed in substantially the same manner as described above is pivotally connected to the connecting portion 13 M:5. Another embodiment of the present invention that is rotatable is shown.

In this embodiment, the connecting portion (bone end surface (36S)

Hole (1 (many locking protrusions (4) toward the center of the chi)
are provided at a predetermined angular pitch. Also, on the inner surface of the connecting piece (6) of the connecting member 07), the locking protrusion QU is provided around the periphery of the through hole.
An engagement +lz concave groove 00 that engages with is provided. Note that the pressing ring (C) is prevented from rotating by fitting the protrusion 0 [K] provided on the back surface with the four portions (17) provided on the end surface (868) of the connecting portion (G).

Therefore, when the front frame (2) is rotatably pivoted to the connecting part (b) using the screw 0→ which is screwed into the screw hole Oe at the bottom of the spring insertion hole (41), the coil spring (l) Due to the biasing action of 02, the locking protrusion 0◇ and the locking groove (c) can be engaged with each other, and the front frame (2) is maintained in that state at an arbitrary inclination angle.

” - As described above, the glasses of the present invention have temples connected to both sides of the front frame via connecting members, and the temples are overlapped with the front frame so that they can be folded, and the front frame can be tilted in the unfolding direction with respect to the temples. As a result, when you need to see through the lenses, you can wear them like regular glasses, and when you wear them, the nose seat fits tightly against your nose and the center of the lenses aligns with your eyes. Since the inclination angle of the front frame is adjusted to fit the glasses, the glasses can be held stably on the face, and the correct vision can be corrected. On the other hand, if there is no need to look through the lens,
By tilting the front frame in the deployment direction with respect to the temple and sliding it down, it becomes possible to see things easily without any obstruction in the field of view. Moreover, the operation is so-called one-touch, and the operability is excellent.

- Also, unlike the above-mentioned conventional eyeglasses, the lenses come close to the eyes during use, which is natural for the eyes.

■In addition, the appearance when in use is exactly the same as normal glasses, and the lens holding frame can be made with eyebrows if necessary, so the glasses of the present invention have the same design as normal glasses. Changes can be made.

-Furthermore, compared to conventional wing-shaped glasses, the temples are thinner when folded, making the case more compact and convenient to carry.

-Furthermore, the position where the booster hits the nose can be changed if necessary, which alleviates nasal pain, especially in glasses with fixed boosters.

In addition, I! of the present invention! [,! In AT, contrary to what was described in the embodiment, the connecting portion between the connecting member and the lens holding frame is pivoted to each other so that the temple can be folded over the front frame, and the connecting member and the temple are connected together. The parts can also be pivoted to each other in such a way that the front frame can be tilted in said angular range.

In addition to the above-mentioned reading glasses, the glasses of the present invention can also be used as glasses for nearsightedness, glasses for farsightedness, and even sunglasses.
When used as sunglasses, when you go from a bright place to a dark place (for example, when you enter a tunnel while driving a car), you can secure your visibility by sliding the front frame down as described above. .
