Description

The present invention relates to eyeglasses, and particularly to a structure for eyeglasses without screws or solder contacts.

There are two types of conventional methods for connecting temples and frames: (1) and (2) below.
(1) A female threaded hole is formed in the temple and the frame at a connection point between the temple and the frame, and the threaded structure of the female threaded hole of the temple and frame is connected by a screw. The disadvantage of this type of connection method is that the frame and temple could be connected by incorporating threaded parts, but if the two are combined and the screws are tightened too tightly, it becomes difficult to open and close. If it was tightened too loosely, there was a risk that the temple would swing vertically and horizontally. Therefore, maintaining the assembly in just the right condition required high precision in the manufacturing process, increasing material processing and production costs. In addition, if glasses with this connection method are used for a long time, the temples may wear out due to repeated opening and closing, causing the connection to become loose, shortening the service life. Limited.
(2) Hook and connect the frame and temple at the connection point. The temple hanging structure is integrally molded using a soldering method. Although this second connection method has been practical in the conventional market, it has many drawbacks like the first connection method described above. First, because the temples of the glasses were on the small side, advanced brazing techniques were required, and the selection of materials had to be fixed, and the materials used for brazing between the hook and the temples had to be uniform. Due to the high requirements for latching and elasticity, the same material had to be used for the temples, increasing production costs. Furthermore, since the connection stability between the temple and the frame was insufficient, there was a risk that the temple would swing up and down. Therefore, there has been a need for a new glasses mounting structure that prevents the frames and temples from swinging up and down. In view of the current situation, the inventor of the present invention has conducted intensive research and has completed the structure of the glasses without screws or soldered contacts of the present invention.

To summarize the above, the screwless and soldered contactless glasses structure according to one embodiment of the present invention has two large and small rectangular holes formed on the temple 2 (temple body). These two holes are the end piece hole 401 (larger hole) and the bullet hole 402 (smaller hole). The hook body 501 (hook) has two reverse hooks with different dimensions. These two reverse hooks are a first hook body 502 (larger hook) and a second hook body 503 (smaller hook), and are inserted into a hole formed in the temple body (temple 2). Two large and small rectangular holes are formed on the bent bullet piece 601. These two holes are the second hook groove 606 (large hole in the bullet) and the first hook groove 605 (small hole in the bullet). The bending elastic piece 601 includes a stress portion 603 having a certain bending width. One rectangular hole is formed on the end piece 701 (the end piece 701 is integrally molded with the frame, and the connection portion between the bending angle of the frame and the temple) (that is, an engagement groove 703). At the same time, one combination tank 702 is formed (the width of the combination tank 702 and the width of the first hook body 502 are approximately the same, so it is formed with just the right dimensions to allow installation; The purpose of this is to allow the end piece 701 to be perpendicular to the bullet when the temple is closed, to hold the bullet on both sides of the end of the end piece 701, and to make the temple swing up and down when the temple is closed. (The purpose is to prevent it from moving), a bullet piece is engaged with the combination tank 702. The entire connection structure is composed of four parts: a temple body structure 4, a hook structure 5, a bullet structure 6, and an end piece structure 7.

(Operating principle)
Insert the hook into the two holes in the temple body. That is, a large hook is inserted into a large hole, and a small hook is inserted into a small hole. After inserting it into the temple body, it is hooked onto the bullet piece. That is, the large hook is inserted into a large hole in the bullet, and the small hook is inserted into a small hole in the bullet. The bullet piece is fixed on the temple body. The bullet piece has a bent shape, and a small hole in the bullet piece is attached to the temple body. The large hole in the bullet piece forms a gap space between it and the temple body. The large hook of the hook is inserted into the large hole of the bullet piece, and the large hook inserted through the large hole of the bullet piece is the outermost layer, and the large hook is inserted into the end piece and connected and fixed. A large hole for the bullet piece is formed in the curved head 604 so that it can be incorporated into the engagement groove 703.

(Effects of each member)
Temple 2 (temple body): Hang on your ears when wearing glasses.
Hook body 501 (hook): Connects the temple (temple body) and end piece.
Bending bullet piece 601: When opening and closing the temple 2, it provides opening and closing force and can stably hold both the open and closed states. When the glasses are open, the curved head 604 is incorporated into the engagement groove 703, thereby preventing the frame 1 and the temple 2 from swinging up and down (elastically connected to reduce vibration). Since the hook is hooked to the bullet piece when the glasses are closed, it is possible to prevent the frame 1 and the temple 2 from swinging up and down.

End piece 701: Contacts the bullet during the opening/closing process of the glasses, providing power and support during the opening/closing process.

(operation effect)
This invention uses the hook, the bullet piece, and the head of the end piece as a fulcrum, mainly due to the physical elasticity of the bullet piece, and uses the physical elasticity of the hook itself to fill the gap between the hook and the glasses after the hook is hung. By combining them, you get the effect of an inner spring and an outer spring. The structure without solder contacts can be replaced with a different material of the bullet and temple at any time as required. Therefore, temples, bullets, hooks, and frames of various materials and colors can be freely exchanged, and the design, manufacture, and use of eyeglasses can be diversified. The bullet is preferably made of high modulus stainless steel, but titanium or shape memory metal may be used as an alternative material. The temple is preferably made of titanium (high elasticity, non-oxidation, does not cause damage to the skin), but alternative materials such as stainless steel, pure titanium, wood, carbon fiber, plastic plate, cow horn, cupronickel, etc. may be used. .
