Description
Technical Field
[0001] This utility model belongs to the field of eyeglass accessories technology, specifically relating to eyeglasses with an elastic hinge. Background Technology
[0002] Eyeglasses are products used to improve vision, protect the eyes, or for decorative purposes. They consist of lenses and frames, and the frames typically include a bridge located between the inner sides of the lenses, a head located on the outer side of the lenses, and temples that are hinged to the head.
[0003] In existing technology, the temples and the frame are connected by screws, resulting in a lack of effective elastic cushioning and positioning mechanisms during rotation. On one hand, the temples easily rotate around the hinge point, preventing a smooth opening and closing motion and causing inconvenience. On the other hand, when worn, the temples lack a stable, ergonomically designed elastic support torque, relying primarily on the wearer's ears and cheeks to maintain the relative angle with the frame. This forces the frame to press against the wearer's nose or face, leading to fatigue, pressure marks, and other discomfort with prolonged wear, resulting in a lack of comfort and stability. Therefore, adjustments to existing traditional eyeglasses are necessary. Utility Model Content
[0004] The purpose of this invention is to overcome the technical problems in the prior art, such as the lack of an effective elastic cushioning and positioning mechanism in the temples during rotation, which affects the comfort and stability of wearing glasses. This invention provides glasses with an elastic hinge, which enables the temples to have an elastic cushioning and positioning mechanism, ensuring the comfort and stability of wearing glasses.
[0005] To solve the above-mentioned technical problems, this utility model provides a pair of eyeglasses, including a frame composed of a bridge, a post, and temples, and lenses connected to the bridge and post respectively. A hinge assembly is provided between the post and the temples. The hinge assembly includes a first hinge member and a hinge portion disposed opposite to each other. A hinge hole is formed in the hinge portion. A connector is provided on the temple. A hinge shaft is provided on both sides of the connector. The hinge shaft is inserted into the hinge hole and rotates with the hinge hole. A central part of the connector is provided with... The push-up protrusion has an elastic sheet integrally formed on the first hinge member, and the elastic sheet is located between the hinge parts. The elastic sheet has a first fixed end connected to the first hinge member and a first free end corresponding to the push-up protrusion. A gap is formed between the first free end of the elastic sheet and its two sides and the first hinge member. When the temple rotates around the hinge axis, the push-up protrusion pushes and slides over the inner side of the first free end of the elastic sheet, causing the elastic sheet to undergo elastic deformation, providing damping and positioning torque for the opening and closing of the temple.
[0006] As a further improvement of this utility model, the hinge and the connector are both located inside the first hinge. The outer side of the push-up protrusion is set as the first contact surface, the end face of the push-up protrusion is set as the second contact surface, and the inner side of the elastic sheet is set as the third contact surface. When the temple is in the unfolded state, the first contact surface and the third contact surface come into contact and abut against each other. When the temple is in the retracted state, the second contact surface and the third contact surface come into contact and abut against each other.
[0007] As a further improvement of this utility model, the inner edge of the lens is provided with a first mounting hole, the two ends of the bridge of the nose are respectively inserted into the first mounting hole, the outer edge of the lens is provided with a second mounting hole, the front end of the stake is inserted into the second mounting hole, and the rear end of the stake is connected to the connector.
[0008] As a further improvement of this utility model, the above-mentioned connector is configured as an "L" shape, the end of the connector perpendicular to the first hinge is configured as a first connecting part, the first connecting part is inserted into the third mounting hole opened at the rear end of the pile head, and the end of the connector parallel to the first hinge is configured as a second connecting part, the second connecting part is connected to the first hinge.
[0009] As a further improvement of this utility model, the above-mentioned hinge assembly also includes a limiting protrusion disposed opposite to each other. The limiting protrusion is located on both sides of the first fixed end of the elastic sheet, and the end of the limiting protrusion facing the post head is set as the limiting end. The end of the limiting protrusion facing the temple is provided with a "U"-shaped snap-fit groove. The hinge part is located on both sides of the first free end of the elastic sheet.
[0010] As a further improvement of this utility model, the second connecting part is provided with a first mounting hole for the limiting protrusion to pass through, and a first clearance groove for accommodating the hinge part.
[0011] As a further improvement of this utility model, the first hinge member is further provided with a limiting plate, and the connecting member is sandwiched between the limiting plate and the first hinge member. The limiting plate is provided with a second assembly hole for the limiting protrusion to pass through, and a second clearance groove for accommodating the hinge part. The end of the second assembly hole facing the temple is formed with a snap-fit edge. When the limiting plate is assembled in place, the snap-fit edge and the snap-fit groove engage with each other.
[0012] As a further improvement of this utility model, a limiting tongue is integrally formed in the second assembly hole. The limiting tongue has a second fixed end connected to the limiting plate and a second free end corresponding to the limiting protrusion. A snap-fit protrusion is formed on the second free end. When the limiting plate is assembled in place, the snap-fit protrusion abuts against the limiting end.
[0013] As a further improvement of this utility model, the aforementioned hinge portion, the limiting protrusion, and the first hinge member are integrally formed.
[0014] As a further improvement of this utility model, the above-mentioned hinge assembly further includes two second hinge members arranged side by side. The hinge part is integrally formed on the end of the second hinge member facing the temple. The limiting protrusion is integrally formed on the end of the second hinge member facing the post. The first hinge member is respectively provided with a third mounting hole for the hinge part to pass through and a fourth mounting hole for the limiting protrusion to pass through. The third mounting hole is located on both sides of the first free end of the elastic sheet, and the fourth mounting hole is located on both sides of the first fixed end of the elastic sheet.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting a hinge assembly with an elastic sheet between the temple and the post, the elastic sheet can generate elastic deformation under the pushing of the pusher during the rotation of the temple, providing damping and positioning torque for the opening and closing of the temple. This enables the temple to have an elastic buffer and positioning mechanism during the opening and closing process, achieving one-step opening and closing of the temple, effectively improving the convenience of using the glasses; 2. When the glasses are worn, the elastic sheet applies a continuous and moderate elastic holding force to the temple through the pusher, keeping the temple at a stable and ergonomic angle, reducing the pressure of the frame and temple on the wearer's nose and face, and significantly improving the comfort and stability of wearing the glasses for a long time; 3. The structure of this utility model is simple. The temple and post do not need to be hinged using traditional screws, so there is no need to drill or tap the temple and post, making it easy to manufacture. Attached Figure Description

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Rather, the present utility model covers any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the present utility model as defined in the claims.
[0028] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.
[0029] Example 1: As Figures 1 to 7 As shown, a pair of glasses includes a frame 4 consisting of a nose bridge 1, a post 2, and temples 3, and lenses 5 connected to the nose bridge 1 and the post 2 respectively. In this embodiment, the lenses 5 may be frameless. A first mounting hole 20 is provided on the inner edge of the lenses 5, and the two ends of the nose bridge 1 are respectively inserted into and fixed in the first mounting hole 20 to realize the connection between the nose bridge 1 and the lenses 5; a second mounting hole 21 is provided on the outer edge of the lenses 5, and the front end of the post 2 is inserted into and fixed in the second mounting hole 21 to realize the connection between the post 2 and the lenses 5.
[0030] To ensure the secure connection between the nose bridge 1, the post 2, and the lens 5, and to prevent loosening or rotation during use, this embodiment designs both ends of the nose bridge 1 and the front end of the post as "U"-shaped hook structures. During assembly, slight pressure causes the arms of the "U"-shaped hook to close, allowing the bottom of the "U"-shaped hook to easily insert into the first mounting hole 20 or the second mounting hole 21 of the lens 5. Once inserted, the external force is removed, and the elasticity of the opening of the "U"-shaped hook causes its arms to open outward and press tightly against the inner surface of the corresponding first mounting hole 20 or second mounting hole 21 for tightening. This design not only enables rapid assembly between the nose bridge 1, the post 2, and the lens 5, but also effectively prevents loosening of the connection through the continuous elastic pressure of the "U"-shaped hook.
[0031] To further increase the connection strength, one option is to process anti-slip grooves on the contact surfaces of the two arms of the "U"-shaped hook to enhance the friction between them and the inner surfaces of the corresponding first mounting holes 20 or second mounting holes 21. Another option is to apply an appropriate amount of structural adhesive to the contact surfaces of the two arms of the "U"-shaped hook and the inner surfaces of the first mounting holes 20 or second mounting holes 21 for bonding and fixing.
[0032] A hinge assembly 6 is provided between the head 2 and the temple 3. In this embodiment, the hinge assembly 6 includes a first hinge member 7 and two hinge portions 8 arranged opposite each other. Both hinge portions 8 are located inside the first hinge member 7, and coaxial hinge holes 9 are provided in both hinge portions 8. A connector 10 is provided on the temple 3. The connector 10 is also located inside the first hinge member 7. Coaxial hinge shafts 11 are provided on both sides of the connector 10. The hinge shafts 11 are respectively inserted into the corresponding hinge holes 9 and rotate with the hinge holes 9. The rotation angle of the hinge shafts 11 is 0~180°, corresponding to the opening and closing movement of the temple 3.
[0033] A push-up protrusion 12 is provided in the middle of the connector 10. An elastic sheet 13 is integrally formed on the first hinge member 7 and is located between the hinge portions 8. The elastic sheet 13 has a first fixed end 14 connected to the first hinge member 7 and a first free end 15 corresponding to the push-up protrusion 12. The hinge portions 8 are located on both sides of the first free end 15 of the elastic sheet 13. A gap 16 is formed between the first free end 15 of the elastic sheet 13 and its two sides and the first hinge member 7, making the elastic sheet 13 a cantilever beam structure that can be elastically deflected.
[0034] When the temple 3 rotates around the hinge axis 11, the pushing protrusion 12 moves synchronously, pushing and sliding over the inner side of the first free end 15 of the elastic sheet 13, forcing the elastic sheet 13 to undergo elastic deformation. This provides damping and positioning torque for the opening and closing of the temple 3, enabling the temple 3 to open and close in one step. Specifically, the outer side of the pushing protrusion 12 is set as the first contact surface, the end face of the pushing protrusion 12 is set as the second contact surface, and the inner side of the elastic sheet 13 is set as the third contact surface. When the temple 3 is in the extended state, the first contact surface and the third contact surface come into contact and abut against each other. When the temple 3 is in the retracted state, the second contact surface and the third contact surface come into contact and abut against each other.
[0035] To achieve the connection between the pile head 2 and the first hinge member 7, an "L"-shaped connector 22 is used as an adapter in this embodiment to connect the rear end of the pile head 2 to the connector 22. Specifically, the end of the connector 22 that is perpendicular to the first hinge member 7 is set as the first connecting part 23, which is inserted into and fixed in the third mounting hole 24 opened at the rear end of the pile head 2; the end of the connector 22 that is parallel to the first hinge member 7 is set as the second connecting part 25, which is connected to the first hinge member 7.
[0036] To achieve a detachable connection between the second connecting portion 25 on the connector 22 and the first hinge member 7, and to ensure precise fixation between the two, the hinge assembly 6 further includes a limiting protrusion 26 disposed opposite to each other. The limiting protrusion 26 is located inside the first hinge member 7 and on both sides of the first fixed end 14 of the elastic sheet 13. The end of the limiting protrusion 26 facing the post head 2 is set as a limiting end 27, and the end of the limiting protrusion 26 facing the temple 3 is provided with a "U"-shaped locking groove 28. In this embodiment, the hinge portion 8, the limiting protrusion 26, and the first hinge member 7 are integrally molded parts to facilitate manufacturing and increase the structural strength of the first hinge member 7.
[0037] The second connecting portion 25 is provided with a first mounting hole 29 for the limiting protrusion 26 to pass through, and a first clearance groove 30 for accommodating the hinge portion 8, so as to realize the initial connection and positioning between the second connecting portion 25 on the connecting member 22 and the first hinge member 7. In order to achieve further locking, the first hinge member 7 is also provided with a limiting plate 31. The limiting plate 31 is provided with a second mounting hole 32 for the limiting protrusion 26 to pass through, and a second clearance groove 33 for accommodating the hinge portion 8. The end of the second mounting hole 32 facing the temple 3 has a snap-fit edge. A limiting tongue 34 is integrally formed in the second mounting hole 32. The limiting tongue 34 has a second fixed end 35 connected to the limiting plate 31 and a second free end 36 corresponding to the limiting protrusion 26. A snap-fit protrusion 37 is formed on the second free end 36.
[0038] During assembly, the connector 22 is first installed on the first hinge 7, and then the limiting plate 31 is installed on the first hinge 7. When the limiting plate 31 is in place, its snap-fit edge and snap-fit groove 28 engage with each other to form the first locking, and its snap-fit protrusion 37 abuts against the limiting end 27 to form the second locking, so that the connector 22 is clamped between the limiting plate 31 and the first hinge 7 for fastening and installation, ensuring the connection between the pile head 2 and the temple 3.
[0039] Example 2: Figures 8 to 10 As shown, this embodiment is largely the same as Embodiment 1, except that the hinge assembly 6 further includes two parallel second hinge members 38. The hinge portion 8 is integrally formed on the end of the second hinge member 38 facing the temple 3, and the limiting protrusion 26 is integrally formed on the end of the second hinge member 38 facing the post head 2. The first hinge member 7 is provided with a third mounting hole 39 for the hinge portion 8 to pass through and a fourth mounting hole 40 for the limiting protrusion 26 to pass through. The third mounting hole 39 is located on both sides of the first free end 15 of the elastic sheet 13, and the fourth mounting hole 40 is located on both sides of the first fixed end 14 of the elastic sheet 13.
[0040] During assembly, two second hinge members 38 are arranged side by side, with the hinge portion 8 and the limiting protrusion 26 on them passing precisely through the corresponding third assembly hole 39 and fourth assembly hole 40, respectively, thereby achieving stable positioning and tight connection between the second hinge member 38 and the first hinge member 7. The assembly method of subsequent connecting members 22, limiting plates 31, etc. is the same as in Embodiment 1.
[0041] Compared to Embodiment 1, where the first hinge 7, hinge portion 8, and limiting protrusion 26 are integrated into a single unit, this embodiment features a separate design between the first hinge 7 and the second hinge 38. This allows the second hinge 38 to be manufactured separately using a high-strength, high-wear-resistant metal material, thereby improving its durability and reliability during long-term use. Furthermore, when long-term use causes wear and damage to the second hinge 38, which is a major moving part, only the individual second hinge 38 can be replaced, without discarding the first hinge 7 or even the entire hinge assembly. This effectively extends the service life of the product body and reduces operating costs.
[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
