Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attachment/detachment device for detachably attaching the temples of eyeglasses.

[Conventional technology]

The glasses have foldable temples on the lens frame.
The ear hook piece provided at the tip of the temple is hooked onto the auricle to be worn. During normal walking, work, and other daily activities, the glasses will not fall off simply by hanging them over the auricles as in the past. However, when doing strenuous sports, the glasses tend to come off easily, so when wearing sports glasses, the temple ear hook is made of elastic metal and is held in such a way as to surround the base of the auricle. shape has been proposed. Therefore, when a person wearing glasses participates in sports, it is necessary to carry two glasses: one for normal use and one for sports. In order to eliminate the inconvenience of carrying these two glasses, a single pair of glasses has been proposed that can be used for both normal use and sports use. It has been proposed that an elastic metal temple for sports is inserted into the temple part and stored, and when playing sports, the metal temple for sports is pulled out and placed on the auricle.

[Problem that the invention attempts to solve]

However, with this structure, since sports items are also accommodated in one temple, the temple is thick, the design is limited, the weight increases, and there is also a problem in the gripping force of the auricle.

In view of this, the present invention aims to make it easy to attach and detach the vines so that you can select and use vines with different designs as necessary, even if they are vines for general use, vines for sports, or vines for general use. purpose.

[Means for solving problems]

The present invention for achieving the above object will be explained using FIGS. 1 to 4 corresponding to embodiments.

The temple attachment/detachment device 7 includes a temple insertion tool 8 which is foldably attached to an end piece 5 which is fixed to the outer side of the spectacle frame body 3 that holds the lens 2 via a hinge 6, and a temple attachment device 8 which is attached to the base end of the temple 4. It consists of a fitting protrusion 9 provided. The temple fitting 8 houses a leaf spring 12 with a locking hook 13 at its tip in an inner hole 11 of a cylinder 10, and the leaf spring 12 has a push button that penetrates through the cylinder 10 and projects outward. 14. The fitting protrusion 9 is a fitting portion 1 that fits into the cylindrical body 10 of the temple fitting 8.
6, and an engaging hook portion 17 formed at the tip of this fitting portion.
It consists of

[Effect]

When connecting the temple 4 to the eyeglass frame body 3, the engagement hook 17 is inserted by inserting the fitting protrusion 9 attached to the base end of the temple 4 into the cylindrical body 10.
meshes with the locking hook piece 13, and the fitting portion 16 fits into the cylindrical body 10 and is connected without play. Further, by pressing the push button 14, the locking hook piece 13 is pushed down against the elasticity of the leaf spring 12, and the engagement with the engagement hook part 17 is released, so that the temple 4 can be easily removed.

〔Example〕

In the figure, eyeglasses 1 include left and right lenses 2, 2, a spectacle frame body 3 that holds the lenses, and left and right temples 4, 4. End pieces 5, 5 are protruded from both outer sides of the eyeglass frame main body 3, or a part of the main body 3 is formed to protrude. An example of the shape of the eyeglass frame main body 3 is shown in the drawing, but it can be configured with a desired design or material other than those shown in the drawing.
The end piece 5 is foldably provided with a temple fitting 8 via a hinge 6, and the temple 4 is provided with a fitting 8.
The inserting tool 8 and the inserting protrusion 9 constitute a temple attachment/detachment device 7. The insertion tool 8 is inserted into the inner hole 11 of the flat rectangular or flat cylindrical cylinder 10, and has a locking hook piece 1 at the tip.
3 is attached to the leaf spring 12, and the leaf spring 12 is flexibly mounted in the vertical direction by the mounting block 15.
is provided with a push button 14 that protrudes through the cylindrical body 10. The fitting protrusion 9 has a fitting portion 16 having an external dimension that fits into the cylindrical bore 11 without any play.
An engaging hook portion 17 that engages with the locking hook piece 13 is formed at the tip of the fitting portion 16, and both the locking hook piece 13 and the engaging hook portion 17 have a right triangular cross section. Then, when inserting the engaging hook portion 17, push down the locking hook piece 13 against the leaf spring 12, and press down the locking hook piece 13 against the leaf spring 12.
The locking hook piece 13 rises due to the elasticity of the leaf spring 12 at the position where it abuts against the insertion tool 8, and engages with the engaging hook portion 17.

The temple 4 has an appropriate shape depending on the purpose, and FIG. 5 shows one example thereof. That is, figure a shows a non-flexible general-use temple 4a bent to the extent that the ear hook piece 21 is hung on the auricle, and figure b shows the ear hook piece 22 bent so as to hold the base of the auricle. Sports vines made flexible by elastic coiled springs, etc. 4
b. Each of these temples 4a, 4b is provided with the above-mentioned fitting protrusion 9 at its base end, and is selected and used depending on the purpose.

The embodiment of the present invention has the above configuration, and has four vines.
(or 4a, 4b hereafter collectively referred to as 4) to the eyeglass frame body 3, simply by fitting the fitting protrusion 9 of the temple 4 into the insertion tool 8, the engaging hook 17 will automatically lock. It meshes with the hook piece 13 and the fitting part 1
6 fits into the cylindrical inner hole 11, so that it is fitted and locked without any play. Next, when removing, by pressing the push button 14, the locking hook piece 13 descends against the elasticity of the leaf spring 12, the above-mentioned engagement is released, and the temple 4 can be removed. Note that the number of the above-mentioned temples 4 is not limited to one for both general use and sports use, and various types with a desired design or color may be prepared and replaced.

[Effect of idea]

According to the present invention, a temple fitting is attached to the eyeglass frame body 3 via the end piece, and the fitting protrusion attached to the temple is fitted into this fitting to automatically connect, and when removed, there is no need to press the fitting. It can be easily removed by pressing a button, and therefore has the effect of allowing the temple to be easily replaced without the use of tools, depending on the application or preference. Moreover, the temple itself only requires a fitting protrusion to be attached to the tip, and the rest has a conventional temple shape, so the external design can be customized to your liking. Furthermore, even if the temples are damaged, the glasses can be reused by simply replacing them with new ones.
