Description

[Detailed Description of the Invention] This invention relates to the creation and improvement of eyeglasses, and more specifically, to the creation of eyeglasses in which the eyeglass frame can be folded with one touch and the lenses can be attached and taken off with one touch.

BACKGROUND ART Conventionally, there have been two types of eyeglasses in which a frame is divided into a plurality of members and each member is rotated by a hinge so that the frames can be folded together, and the other is a pair of eyeglasses in which the lens is detachable by the user.

However, in the former case, a separate locking mechanism is required to prevent each member from inadvertently rotating at the connecting part when wearing glasses, which complicates the structure.
In the latter case, for example, as in the invention of Utility Model Application Publication No. 55-60108, a set screw is required to attach and detach the lens, making it impossible to easily attach and detach the lens with one touch. In this way, a separate mechanism is required to lock the locking device for fixing the lens in the locked position, which complicates the structure, and there is a risk that the lock may loosen during use and the lens may fall off. Because of the structure in which a ring-shaped lens frame surrounds the lens, the shape of the lens is restricted by the shape of the lens frame, and there are disadvantages such as only one type of lens design can be used in one eyeglass frame. be.

The purpose of this invention is to provide glasses that eliminate these inconveniences.

The first feature of the glasses of this invention is that the left and right lens frames are connected by a hinge, and the lens frame is further divided into a front half and a rear half, which are connected by a hinge, and the opening and closing directions of each hinge are all in the plane direction. The pivots of each hinge are all provided inside the eyeglass frame, so that the eyeglass frame can be folded with one touch.

Next, the second feature is that the lower half of the lens frame is open so that the lens can be attached from below, and only the upper half of the lens is surrounded. The lens to be attached to the lens frame is provided with a pair of engagement protrusions corresponding to these engagement holes and grooves, and a lens connecting fitting is provided to connect the lens frame and the lens frame. A rotatable cover is provided on the lens frame, and a cover protrusion is provided on the back side of the cover to cover the opening of the engagement notch of the lens frame. After the lens is attached to the lens frame from below, the cover is removed. The lens is fixed to the lens frame by superimposing it on the lens connecting metal fitting to cover the engagement notch and the engaging protrusion, and furthermore, this cover is pivoted using the pivot between the lens connecting metal fitting and the lens. In addition, when the lens is opened when the eyeglasses are worn at the pivot point, the end face of the eyelet presses the eyelet side end face of the cover in the overlapping direction of the cover, thereby preventing the lens from falling off when the eyeglasses are worn. It was a good idea.

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

FIG. 1 is a front view of the glasses of this invention with one lens removed, and FIG. 2 is a plan view of the same.

In the glasses of this invention, a pair of left and right lens frames 1, 1 are connected by a hinge 3, and a frame 4, which is divided into a front part 4a and a rear part 4b and connected by a hinge 9, is attached to the lens frame 1, and one end is connected to the lens frame 1 by a hinge 9. By connecting with the lens connecting fittings 5 formed in the part 6, the left and right lens frames can be freely folded into each other, the lens frame and the lens, and the front and rear parts of the lens (see FIG. 3).

In the above-mentioned folding process, the opening and closing directions of the hinges 3 and 9 are made to be in the plane direction, so that all the members are folded in the plane direction, and the pivots 3a and 5a of each hinge are positioned inside the eyeglass frame. As a result, each member is configured to rotate only within a range of 180 degrees inside the eyeglass frame, and cannot rotate beyond that due to abutment between the end surfaces of each member.

Furthermore, in this embodiment, the bridge 2 that connects the left and right lens frames is divided into a left half 2a and a right half 2b, and a hinge 3 is placed between the two to serve as a means for connecting the left and right lens frames. , as shown in FIG. 9, hinges 3', 3' may be installed between the left and right ends of the bridge 2' and the left and right lens frames, respectively.

The lens frame 1 has a groove 1c formed inside thereof for fitting the lens L, and is configured with the lower half open so that the lens L can be attached from below.

The lens frame 1 has an engagement hole 1b at its bridge side end (see FIGS. 5 and 6), and an open part at its front end is covered by a covering protrusion 7a of a cover 7, which will be described later. The lens L to be attached to the lens frame is provided with an engaging projection 8b corresponding to the engaging hole 1b and the engaging notch 1a (see FIGS. 4 and 7). and 8a
Provide a pair of

As a means for providing the above-mentioned engaging protrusions 8b and 8a on the lens L, in this embodiment, a means for preparing a peripheral metal fitting 8 to be fitted to the peripheral edge of the lens and fixing the above-mentioned engaging protrusions to this peripheral metal fitting is adopted. However, in this case, in addition to the peripheral metal fitting 8 that surrounds the entire circumference of the lens as shown in Figure 1, there is also a peripheral metal fitting that surrounds only the upper half of the lens and suspends the lower half with nylon thread or the like. It may be 8'.

FIG. 4 is a perspective view showing details of the hook connecting fitting and the cover portion.

The lens connecting fitting 5 has a function of rotatably connecting the lens frame 1 to the lens frame 1 by forming a hinge part 6 at one end and fixing the hinge piece 6b to the lens frame 4. It roughly corresponds to a metal fitting called ``chi'' or ``hinge,'' but it has a function that makes it impossible to rotate more than 180 degrees with respect to the hinge that conventional metal fittings had [in other words, the lens frame The difference is that the cover 7 does not have the function of keeping the bar at right angles to the air, and that function is performed by a cover 7, which will be described below.

The cover 7 has a shape that covers and overlaps the outer side surface of the hook connecting fitting 5, and has a hinge piece 7b provided at one end.
By pivotally connecting the hook connecting fitting 5 and the hook 4 using the pivot shaft 6a, the hook connecting fitting 5 and the hook 4 can be rotated in the overlapping and detaching directions with respect to the hook connecting fitting.

The main purpose of this cover 7 is to cover the engagement notch 1 after the engagement protrusion 1a of the lens 1 is fitted, as described above.
For this purpose, a cover protrusion 7a is provided on the back side of the cover at a position corresponding to the engagement notch (see FIG. 7).

When the cover 7 is pivoted, the cover is attached at an angle of 180 degrees with respect to the cover so that when the cover 4 is opened when wearing glasses, the end face of the cover presses the cover side end face in the overlapping direction of the cover. Adjust the end surfaces of both sides in advance so that they will come into contact when the side surface of the cover is positioned at 180 degrees to the side surface of the shank so as not to rotate more than an angle (see Figure 8). By adjusting in this way, when wearing glasses, the cover 7 is fixed in the overlapping state by the pressure from the lens 4, and therefore the covering state of the engagement notch 1a is locked, preventing the lens 1 from falling off. It also functions to keep the lens 4 perpendicular to the lens frame 1.

This invention is constructed as described above and has the following effects.

Since the eyeglass frame is divided into left and right lens frames and the front and rear halves of the frame, the frame can be folded freely.
It can be folded into an extremely compact size, and the lens is detachable, so if you remove the lens when folded and carry it around, you can safely store it in a bag, pocket, etc. without damaging it due to external loads on the frame. be able to.

By making all the folding directions planar, the eyeglass frame can be folded with a single touch by a unidirectional movement.Furthermore, in addition to making all the folding directions planar, the pivots of each hinge are all placed inside the frame. By adjusting the end faces so that each connected member does not rotate more than 180 degrees, it is possible to prevent each member from inadvertently rotating when wearing glasses without the need for a special locking mechanism. can.

The lower half of the lens frame is open and only the upper half of the lens is enclosed, and the lens is fixed using an engaging protrusion provided on the lens, so the shape of the lens is limited only to the upper half, while the lower half is closed. The design of the halves becomes free, and it is possible to combine not only the functional types of lenses (for example, different colors, for farsightedness, nearsightedness, etc.), but also lenses of multiple designs in one eyeglass frame (for example, as shown in Figures 10 and 11). lenses shown].

In addition to the lens fixing method described above, the engaging notch is covered by a covering protrusion provided on the rotatable cover, so the user can easily attach/remove/replace the lens without using any special tools. Furthermore, when wearing glasses, the cover is rotated and fixed in the overlapping state by pressure from the lens, so it is possible to prevent the lenses from falling off without using a special locking mechanism, and there is no chance of the lock loosening.
