The method of using the elastic member to connect with the temple to provide elasticity for the temple is not only simple in structure, but also easy to process and low in cost.

Description

Technical Field

[0001] The present invention relates to the technical field of frame glasses, and particularly to a temple hinge. Background Art

[0002] Frame glasses usually consist of lenses, a lens frame, nose pads, temple mounts, hinge pieces, and temples. The lenses are installed in the lens frame, the nose pads and temple mounts are connected to the lens frame, the hinge pieces are connected to the temple mounts, and the temples are pivotally connected to the hinge pieces so that the temples can rotate relative to the lens frame around the hinge pieces to achieve the temple folding function. With the development of frame glasses technology, elastic glasses technology has emerged. The purpose of elastic glasses technology is to improve the extensibility of the temples, enable the frame glasses to adapt to different face shapes, and disperse the force on the facial support points of the frame glasses to avoid changing the original shape of the frame glasses due to external forces, resulting in a change in the distance between the lenses and the eyes and endangering eyesight. In traditional technology, an elastic hinge is added between the hinge piece and the temple, and the elastic hinge is elastically connected to the temple to improve the extensibility of the temple. However, current elastic hinges are all hinges with springs, which not only have many parts and a complex structure, but also have a large processing difficulty and high cost.

[0051] Embodiment 1:

[0052] Please refer to Figure 1 and Figure 2 , which is a temple hinge for Embodiment 1 of the invention, used to be connected to the temple 4 to improve the extendability of the temple 4. The temple hinge includes a hinge head 2 and an elastic member 3. The hinge head 2 is provided with a pivot hole 21 for inserting a pivot member 5 to pivotally connect with the hinge plate 1; the elastic member 3 includes a connecting portion 31, a spring plate portion 32 and a supporting portion 33. The connecting portion 31 and the spring plate portion 32 are both located at one end of the supporting portion 33. The connecting portion 31 is connected to the hinge head 2, and the spring plate portion 32 extends to one side of the pivot hole 21.

[0053] The elastic member 3 is a sheet-like structure. It can be understood that the elastic member 3 is an end straight thin sheet with elasticity. The sheet-like elastic member 3 is easy to process and install, which is conducive to realizing automation.

[0054] The elastic member 3 is made of either metal or plastic. The elastic member 3 made of metal has high strength and stable structure, while the elastic member 3 made of plastic is light in weight, has good ductility and long service life. It can be understood that the elastic member 3 is used to support the hinge joint 2 and connect the temple 4. The functions included in the selected material of the elastic member 3 can be one or several of good strength, stable structure, light weight, good ductility and long service life, which will not be elaborated here.

[0055] Please refer to again Figure 2 , the elastic member 3 includes a snap portion 34. The snap portion 34 is located on one side of the support portion 33. The snap portion 34 extends away from the support portion 33. The snap portion 34 and the support portion 33 are spaced apart to form a pressing space 37. The snap portion 34 elastically expands and contracts within the pressing space 37; the elastic expansion and contraction of the snap portion 34 within the pressing space 37 enables the elastic member 3 to be snapped onto the temple 4 through the snap portion 34, thereby realizing the quick disassembly and assembly of the elastic member 3 and the temple 4. When the elastic member 3 is damaged, it is easier to disassemble and assemble the elastic member 3, improving the maintenance economy and use convenience of the elastic member 3.

[0056] The elastic member 3 further includes a stop portion 35. The stop portion 35 is located on the side of the snap portion 34 close to the support portion 33. The stop portion 35 extends in the direction in which the snap portion 34 extends. The stop portion 35 is used to cooperate with the snap portion 34 to make the snap portion 34 more stably snapped onto the temple 4, thereby improving the stability of the snap connection of the snap portion 34.

[0057] The elastic member 3 further includes an insertion handle portion 36. The insertion handle portion 36 is located at the end of the support portion 33 away from the connection portion 31. The insertion handle portion 36 is used for the fixed connection between the support portion 33 and the temple 4, improving the connection stability between the elastic member 3 and the temple 4.

[0058] The insertion handle portion 36 is located in the middle region of the support portion 33. The insertion handle portion 36 located in the middle region of the support portion 33 can provide better support for the support portion 33, thereby preventing the elastic member 3 from shaking during use, and thus improving the use accuracy of the elastic member 3.

[0059] The side of the insertion handle portion 36 is adjacent to the side of the support portion 33. The insertion handle portion 36 adjacent to the side of the support portion 33 can increase the rigidity of the support portion 33, thereby improving the stability of the overall structure of the elastic member 3 during use, and thus improving the use accuracy of the elastic member 3.

[0060] Please refer to Figure 3, the hinge joint 2 includes a first side plate 22, a second side plate 23 and a connecting block 24. The first side plate 22 and the second side plate 23 are respectively connected to opposite ends of the connecting block 24. The connecting block 24 is connected to the connecting portion 31. The pivot hole 21 passes through the first side plate 22 and the second side plate 23. The elastic piece portion 32 is located between the first side plate 22 and the second side plate 23. The first side plate 22 and the second side plate 23 can control the extension direction of the temple 4 by restricting the telescopic direction of the elastic piece portion 32, thereby improving the extension accuracy of the temple 4. Moreover, the first side plate 22 and the second side plate 23 can protect the elastic piece portion 32, enhance the strength of the elastic piece portion 32, and extend the service life of the elastic piece portion 32.

[0061] Please refer again to Figure 2 , the connecting portion 31 is provided with a connecting groove 311 corresponding to the connecting block 24. By mating the connecting groove 311 with the connecting block 24, the position accuracy of the connecting portion 31 and the connecting block 24 during assembly can be improved, thereby improving the position accuracy of the elastic piece portion 32 during assembly, and further improving the extension accuracy of the temple 4.

[0062] The connecting portion 31 is fixedly connected to the first side plate 22, the second side plate 23 and the connecting block 24. The way of fixedly connecting the connecting portion 31 to the first side plate 22, the second side plate 23 and the connecting block 24 can adopt one or more of gluing or welding methods. Fixing the first side plate 22, the second side plate 23 and the connecting block 24 of the hinge joint 2 to the connecting portion 31 can improve the connection strength between the connecting portion 31 and the hinge joint 2, as well as the relative position accuracy between the connecting portion 31 and the hinge joint 2, and further improve the extension accuracy of the temple 4 during extension.

[0063] It can be understood that the hinge joint 2 and the elastic member 3 are an integrally formed whole. The integrally formed hinge joint 2 and elastic member 3 are simple to assemble, convenient to disassemble and assemble, and are beneficial to improving the assembly efficiency or the automatic assembly of the temple hinge.

[0064] Furthermore, the hinge joint 2 and the elastic member 3 are one of integrally formed metal or plastic. Specifically, the hinge joint 2 and the elastic member 3 can be integrally formed by one or several of 3D printing, precision casting or injection molding.

[0065] Please refer to Figures 4 to 6 , a pair of glasses, including the temple hinge described in Embodiment 1 of the present invention. The glasses further include temples 4. The temples 4 include a body 41, a first insertion portion 42, a second insertion portion 43 and an abutting portion 45. The body 41 is connected to the elastic member 3. The first insertion portion 42 and the second insertion portion 43 are spaced apart on one side of the body 41 close to the elastic member 3. The abutting portion 45 is located between the first insertion portion 42 and the second insertion portion 43. The abutting portion 45 is spaced apart from the body 41. The abutting portion 45 is used for the snap portion 34 to snap onto.

[0066] Please refer to Figure 6, the temple 4 includes a body 41, and the body 41 is provided with a slot 411 corresponding to the insertion handle portion 36. The insertion handle portion 36 of the temple hinge is inserted into the slot 411 to be connected to the body 41. The slot 411 of the temple 4 facilitates the connection between the temple hinge and the temple 4, improving the convenience of the connection between the temple 4 and the temple hinge.

[0067] The first insertion portion 42 and the second insertion portion 43 are relatively spaced apart. One ends of the first insertion portion 42 and the second insertion portion 43 are both connected to the side of the body 41 having the slot 411. The first insertion portion 42, the second insertion portion 43 and the body 41 enclose an open through groove 44, and the open through groove 44 is used to accommodate the support portion 33 and part of the connecting portion 31 and the elastic piece portion 32. Protecting the support portion 33 by accommodating the support portion 33 and part of the connecting portion 31 through the open through groove 44, avoiding damage to the support portion 33 caused by direct contact with the outside world. Moreover, the first insertion portion 42 and the second insertion portion 43 can limit the telescopic direction of the elastic piece portion 32, thereby increasing the telescopic accuracy of the temple 4.

[0068] The first insertion portion 42 is provided with a first positioning groove 421, the first side plate 22 is provided with a first positioning portion 221 corresponding to the first positioning groove 421, the second insertion portion 43 is provided with a second positioning groove 431, and the second side plate 23 is provided with a second positioning portion 231 corresponding to the second positioning groove 431. The first positioning groove 421 is used for the first positioning portion 221 to be inserted, and the second positioning groove 431 is used for the second positioning portion 231 to be inserted. The hinge head 2 is inserted into the first positioning groove 421 and the second positioning of the temple 4 through the first positioning portion 221 and the second positioning portion 231, which can improve the assembly accuracy of the hinge head 2 and the temple 4, thereby improving the extension accuracy of the temple 4 during use.

[0069] It can be understood that the first side plate 22 is provided with a first positioning groove 421, the first insertion portion 42 is provided with a first positioning portion 221 corresponding to the first positioning groove 421, the second side plate 23 is provided with a second positioning groove 431, and the second insertion portion 43 is provided with a second positioning portion 231 corresponding to the second positioning groove 431.

[0070] Or, the first side plate 22 is provided with a first positioning groove 421, the first insertion portion 42 is provided with a first positioning portion 221 corresponding to the first positioning groove 421, the second side plate 23 is provided with a second positioning portion 231, and the second insertion portion 43 is provided with a second positioning groove 431 corresponding to the second positioning portion 231.

[0071] Or, the first side plate 22 is provided with a first positioning portion 221, the first insertion portion 42 is provided with a first positioning groove 421 corresponding to the first positioning portion 221, the second side plate 23 is provided with a second positioning groove 431, and the second insertion portion 43 is provided with a second positioning portion 231 corresponding to the second positioning groove 431.

[0072] It can be understood that various assembly methods can be combined through the insertion of the first positioning portion 221 and the second positioning portion 231 into the first positioning groove 421 and the second positioning groove 431. The purpose of the first positioning portion 221, the second positioning portion 231, the first positioning groove 421, and the second positioning groove 431 is to improve the assembly accuracy of the hinge head 2 and the temple 4. There can be various different combinations by arranging the first positioning portion 221, the second positioning portion 231, the first positioning groove 421, and the second positioning groove 431, which will not be elaborated here.

[0073] Please refer to again Figure 5 , the abutting portion 45 is located between the first insertion portion 42 and the second insertion portion 43. The abutting portion 45 is spaced apart from the body 41. The abutting portion 45 is used for the snap portion 34 to be snapped.

[0074] Specifically, the abutting portion 45 has a vertical surface 451 and a bottom surface 452. The vertical surface 451 is located on the side of the abutting portion 45 opposite to the body 41, and the bottom surface 452 is located on the side adjacent to the bottom surface 452.

[0075] Please refer to again Figure 2 , the snap portion 34 has a contact surface 341 corresponding to the vertical surface 451. The contact surface 341 is located on the side of the snap portion 34 away from the support portion 33. When the snap portion 34 needs to be snapped with the abutting portion 45, when the end of the elastic member 3 with the snap portion 34 is inserted into the opening through groove 44 towards the abutting portion 45, the snap portion 34 contacts the abutting portion 45 and is compressed into the pressing space 37. When the elastic member 3 is inserted into the opening through groove 44 in place, the snap portion 34 pops out from the pressing space 37, and the contact surface 341 of the snap portion 34 abuts against the vertical surface 451 of the abutting portion 45, thereby realizing the snapping of the snap portion 34 and the abutting portion 45.

[0076] The stop portion 35 has a stop surface 351 corresponding to the bottom surface 452. The stop surface 351 is located on the side of the stop portion 35 adjacent to the contact surface 341. The stop surface 351 and the contact surface 341 are arranged in an L shape. The abutting portion 45 abuts against the stop surface 351 through the bottom surface 452, thereby preventing the contact surface 341 from disengaging from the vertical surface 451.

[0077] Please refer to again Figure 5 and Figure 6 , both the first insertion portion 42 and the second insertion portion 43 have an arc-shaped concave surface 46. The arc-shaped concave surface 46 can be arc-shaped or L-shaped. Each arc-shaped concave surface 46 is located between the body 41 and the abutting portion 45. Each arc-shaped concave surface 46 is used to provide a space for pressing the snap portion 34. The arc-shaped concave surface 46 can facilitate pressing the snap portion 34 and improve the usability of the snap portion 34.

[0078] The arc-shaped concave surface 46 is in a hook shape. The arc-shaped surface of the hook shape facilitates observing whether the contact surface 341 of the snap portion 34 is in contact with the vertical surface 451 of the abutting portion 45, so as to judge whether the snap portion 34 is buckled with the abutting portion 45.

[0079] The arc-shaped concave surface 46 is circular arc-shaped. The arc-shaped surface of the circular arc shape facilitates pressing the snap portion 34, thereby improving the pressing effect of the snap portion 34.

[0080] For the above-mentioned spring hinge, when in use, the connecting portion 31 of the elastic member 3 can be first inserted into the connecting block 24 of the hinge head 2 for fixed connection. The fixed connection method here can adopt bonding or welding or a combination of bonding and welding. Then, the hinge head 2 is pivotally connected to the hinge piece 1 through the pivot hole 21. Finally, the supporting portion 33 and the inserting handle portion 36 of the elastic member 3 are inserted into the temple 4, and the snap portion 34 of the elastic member 3 is buckled with the temple 4 to realize the buckling connection between the elastic member 3 and the temple 4. When in use, since the spring piece portion 32 extends to one side of the pivot hole 21, when the temple 4 extends, the temple 4 drives the elastic member 3 to rotate around the pivot member 5, and the spring piece portion 32 contacts the hinge piece 1. When the temple 4 continues to rotate, the spring piece portion 32 is extruded by the hinge piece 1 to generate deformation. The deformed spring piece portion 32 provides a thrust force in the opposite direction to the temple 4. While increasing the extension degree of the temple 4, the temple 4 has a certain clamping force. And, by the spring piece portion 32 abutting against the hinge piece 1, a sense of jerk will be generated when the hinge piece 1 rotates through the dead point position. By the elastic force provided by the spring piece portion 32, it is beneficial to quickly close or open the temple 4 with the glasses. The elastic member 3 is connected to the temple 4 to provide an elastic structure for the temple 4, which not only has a simple structure, is convenient for processing, but also is easy to assemble and has a low cost.
