Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eyeglass frame in which left and right lenses are connected to each other without using a rim.

[0002]

[Prior art]

 The spectacle frame is a kind of tool for fixing the lens and putting it on the face, and its shape is diverse and diversified. In general, the left and right rims are connected via a bridge, and an outer end of both rims is brazed with an endowment, and a crane is connected to the endless end in a foldable state. The rim is in the form of a closed ring and has a structure capable of fitting to the outer periphery of the lens to fix the lens, but the rim of the rim is designed to reduce the weight and increase the field of view of the spectacle frame. There is also a structure where the lower half is removed and a lens can be held in this part by using water threads.

Further, there is also known a structure in which the left and right lenses are screwed with a connecting member (bridge) interposed therebetween without using a rim at all. Therefore, in this case, the end piece that connects the crane is also screwed to the outer end of the lens. Since the connecting member and the yoke are made of metal, they are not directly contacted with the lens surface to be screwed, but are screwed through a packing made of rubber or the like.

By the way, in a frame that does not use a rim, the bending moment that acts when opening and closing the temple directly affects the lens and causes damage to the lens. When the glasses are worn, the temples are opened, and even when the temples are worn, the temples contact the side of the face with a certain pressing force. Maximum bending moment is generated in the connecting member. The strength of the metallic connecting member is high, and therefore the connecting member will not be damaged, but instead the screwed part with the lens will be damaged.

Further, in addition to the action of the moment, even when an external force directly acts on the lens, there is no means for letting the external force escape, and therefore the lens is often damaged. The point where the lens breaks is not only the contact part with the connecting member, but also the contact part with the armature. Then, the connecting member and the lens and the end piece and the lens are fixed by screws through packing, but this screw fixing work is very troublesome. Further, in this screw fixing structure, the length of the screw to be used varies depending on the thickness of the lens, and one problem is that screws of various sizes must be prepared. Generally, it is tightened with long screws and cut later.

[0006]

[Problems to be solved by the present invention]

 As described above, the conventional spectacle frame that does not use the rim has the above problems. The problems to be solved by the present invention are these problems, and provide a spectacle frame that can be connected to a lens without damaging the lens and without using a screw.

[0007]

[Means for Solving the Problems]

 Since the spectacle frame of the present invention is constructed without using a rim and the lens is directly fixed, the connecting member is disposed between the left and right lenses, and the armature is positioned outside the lens to be fixed to the lens. It The connecting member is made of a highly elastic resin and is integrally molded. One end piece is composed of two pieces, a broach part for fixing the lens directly and an end part, and the broach part is made of a highly elastic part. However, the end part may be made of resin or metal parts. The broach part and the end part are screwed together to form a predetermined end part.

Here, the present invention employs a belt lock mechanism as a connecting means for connecting the lens to the connecting member and the end piece. Therefore, a belt is formed in the connecting member and the broach portion of the end piece, and the belt is inserted through the hole formed in the lens and inserted into the lock holes provided in the connecting member and the broach portion and fastened. Of course, the connecting member and the broach portion have a contact piece that comes into contact with the outer peripheral surface of the lens, and the belt is fastened in a state where the corresponding piece is in contact. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
