[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for connecting an armor to a lens rim and a structure for connecting a bridge to a lens rim.

[0002]

[Prior art]

 The general structure of the conventional connecting structure of the armature or bridge to the lens rim has been to braze the ends of the armature or bridge to the inside or outside of the lens rim.

[0003]

[Problems to be solved by the device]

 Therefore, when the conventional connecting structure is used, not only skill is required for brazing, but also labor and time are required for the work, resulting in poor manufacturing efficiency and increase in manufacturing cost. In addition, since the armor and bridge are inseparably connected to the lens rim by brazing, even if there is a request to change the eyeglass design and enjoy fashion by exchanging the armor and bridge, we can not respond to it at all. It was In addition, because of the inability to separate, there is also a problem in terms of safety, such as when the face is impacted during skiing, the face may be scratched by eyeglasses.

Therefore, the present invention facilitates the assembly of the eyeglasses and enables the change of the eyeglasses design by exchanging the royers and bridges, and also contributes to the improvement of the safety of the spectacles. The purpose is to provide a connection structure.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention adopts the following means. That is, one aspect of the connecting structure according to the present invention is that an engaging protrusion is provided at a vertically opposed portion or a front-rear opposed portion of a joint protrusion that is provided at an outer portion of a lens rim, and a tip side portion of an end piece Is provided with a holding portion having a pair of holding pieces that sandwich the joint protruding portion from above and below or from the front and rear, and both holding pieces are formed with engaging cavities capable of fitting with the engaging protruding portions. The holding part is made of a resin having elasticity, and can be elastically expanded so that the engaging protrusion and the engaging space can be fitted together, and both holding parts can be returned to the initial state. The engagement projection and the engagement space are thereby retained in a fitted state by being engaged with each other.

In another aspect of the connection structure according to the present invention, an engaging protrusion is provided at a vertically opposing portion or a front-rear opposing portion of a joint protrusion provided at an inner portion of a lens rim, and a bridge is provided. At the tip end side portion thereof, there is provided a gripping portion formed of a pair of gripping pieces that sandwich the joint projection from above and below or in the front and back, and both of the gripping pieces are engaged with the engaging projections. The holding part is formed of a resin having elasticity, and the holding part can be elastically expanded so that the engaging protrusion and the engaging space can be fitted together. It is characterized in that the engagement projection and the engagement space are held in a fitted state by being returned to the state.

In each of the above-mentioned connection structures, it is preferable that the engaging protrusion is formed in a rectangular parallelepiped shape or a cubic shape, and the engaging space is formed as a hole that can be fitted into the engaging protrusion. Further, it is preferable to provide a fitting groove into which the lens rim can be fitted, at the tip portion of the holding piece.

[0008]

[Action]

 However, after elastically expanding the two holding pieces, aligning the engaging projections that are provided to face the joint projections with the respective engaging cavities of the holding pieces, return both holding pieces to the initial state. When the engaging protrusion and the engagement space are fitted to each other, the armature and the bridge are connected to the lens rim in a state in which both the holding pieces hold the joint protrusion. In order to remove the bridge or armature in such a connected state, both holding pieces are opened to release the fitting state between the engaging projection and the engaging space.

In particular, the engagement protrusion is formed into a rectangular parallelepiped shape or a cube shape, and the engagement cavity is configured as a hole with which the engagement protrusion fits, so that the engagement protrusion is fitted into the engagement cavity. Depending on the combination, the armor and bridge will be locked against the lens rim and connected.

Further, since the fitting groove into which the lens rim can be fitted is provided in the tip portion of the sandwiching piece, the lens rim is fitted into the fitting groove, whereby the armature and the bridge are prevented from rotating with respect to the lens rim. Will be connected.

[Effect of device]

 The present invention has the following excellent effects. Since the present invention is configured as described above, when connecting the armature or the bridge to the lens rim, both holding pieces are elastically expanded and the engaging projections provided opposite the joint projections are held. After aligning each of the engaging cavities of the one piece with each other, the both holding pieces are returned to the initial state and the engaging projection and the engaging vacancy are brought into a fitted state, and the both holding pieces hold the joint projection. In this state, the armor and bridge will be connected to the lens rim. Then, in order to remove the bridge and the end pieces that are in such a connected state, both holding pieces can be opened to release the fitting state between the engaging projection and the engaging space.

As described above, according to the present invention, the connection of the armature and the bridge to the lens rim can be simply and quickly performed by the one-touch operation without requiring the skill required in the conventional brazing connection means. Also, since the armor and bridge can be easily removed, the design of the ophthalmoscope can be changed by exchanging the armor and bridge with a desired design, and you can enjoy fashion.

Since the present invention has the connection structure by the fitting method of the concavo-convex structure, the connection is normally maintained accurately, but the connection is released when a shock is applied to the face during skiing, for example. It has safety that does not hurt the face.

Particularly, when the engaging protrusion is formed in a rectangular parallelepiped shape or a cubic shape and the engaging space is formed as a hole which can be fitted with the engaging protrusion, the engaging protrusion is engaged. By mating with the joint space, the armor and bridge can be connected to the lens rim in a non-rotating state. Further, when a fitting groove into which the lens rim can be fitted is provided in the tip end portion of the sandwiching piece, by inserting the lens rim into the fitting groove, the armature or the bridge can be connected to the lens rim in a non-rotating state.
