Description

Technical Field

[0001] This invention relates to the field of eyeglasses, and more specifically to a hinge structure for eyeglasses and eyeglasses having the hinge structure. Background Technology

[0002] Currently, most eyeglasses use metal screws to hinge and secure the temples and frames. This screw-based hinge method has the following drawbacks: 1. During assembly, screws are prone to stripping, leading to a lengthy production process and difficulties in quality control; 2. Screws tend to loosen after prolonged use; 3. The product is relatively heavy, making weight reduction impossible; 4. The range of motion of the temples is fixed. If the user has a wide head, wearing them can cause a feeling of pressure, and the glasses themselves cannot effectively relieve this pressure, leading to discomfort over long periods. Therefore, this causes numerous problems for users. Summary of the Invention

[0003] Therefore, the present invention provides a hinge structure for eyeglasses and eyeglasses having the hinge structure, thereby changing the hinge structure of eyeglasses to achieve screwless hinge; thus effectively solving the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0005] A hinge structure for eyeglasses includes a first connector, a second connector, and a third connector. The first connector is used to connect to a frame. The second connector is fitted onto the first connector and has a hinge notch facing away from the frame. The third connector is used to connect to the temple and has a hinge protrusion, the hinge protrusion of the third connector being rotatably fitted into the hinge notch of the second connector. The first connector also abuts against the third connector to prevent the hinge protrusion of the third connector from disengaging from the hinge notch.

[0006] Furthermore, the second connector has two spaced-apart connecting pieces, and the hinge notch is formed on the two connecting pieces; the third connector has two coaxially arranged hinge protrusions, which are rotatably fitted into the hinge notches of the two connecting pieces respectively.

[0007] Furthermore, the third connector has a cross-shaped structure, including a horizontally arranged crossbar and a vertically arranged vertical bar. The first end of the crossbar is connected to the temple, and the two ends of the vertical bar form two coaxially arranged hinged protrusions. The crossbar is located in the gap between the two connecting pieces.

[0008] Furthermore, the end face of the second end of the crossbar is a plane.

[0009] Furthermore, the third connector is integrally connected to the temple.

[0010] Furthermore, the first connector is an integral extension of the frame.

[0011] Furthermore, the first connector has an "L" shaped structure, including a first part connecting the frame and a second part connecting the first part and being angled to it. The second connector includes two spaced-apart connecting pieces and a fixing piece connecting the two connecting pieces. The two connecting pieces and the fixing piece form a U-shaped groove. The first end of the connecting piece forms a limiting step with the fixing piece. The second end of the connecting piece extends outward at an angle to form an extension arm. The hinge notch is formed on the extension arm. The first part of the first connector passes through the U-shaped groove of the second connector. The limiting step is engaged with the frame. The second part of the first connector corresponds to the hinge notch and abuts against the third connector.

[0012] Furthermore, the first connector is detachably mounted on the frame.

[0013] Furthermore, the first connector has an "L" shaped structure, including a first part that connects to the frame and a second part that connects to the first part and is set at an angle to the first part. The first part is detachably and fixedly inserted into the frame, and the second part connects to the second connector and abuts against the third connector.

[0014] Furthermore, the second connector includes two spaced-apart connecting pieces and a fixing piece connecting the two connecting pieces. The fixing piece is located between the first end and the second end of the connecting piece. The first end of the connecting piece has a first limiting step. The hinge notch is formed on the outer side wall of the connecting piece near the second end. The outer side wall of the second part of the first connector has a second limiting step. The second part passes between the two connecting pieces. The first limiting step of the connecting piece is engaged with the inner side wall of the second part. The second limiting step of the second part is engaged with the fixing piece. The outer end of the second part abuts against the third connector.

[0015] A pair of eyeglasses, comprising at least the hinge structure described above.

[0016] The technical solution provided by this invention has the following beneficial effects:

[0017] 1. The third connector is rotatably fitted into the hinge notch of the second connector via a hinge protrusion and is restrained by the first connector, thereby enabling the temple connected to the third connector to fold and unfold normally, achieving screwless hinge. This effectively avoids the problems of stripping and loosening during assembly caused by screw hinges, and effectively improves assembly efficiency and stability of use.

[0018] 2. The screwless hinge structure allows the first, second, and third connectors to be made of lightweight materials (such as plastics), effectively reducing weight and achieving lightweight design.

[0019] 3. The first connector restricts the hinge protrusion within the hinge notch by abutting. When the temple is extended, the continued extension of the temple can force the first connector to deform and have a certain outward expansion space, which can effectively release the pressure and make it more comfortable to wear.

[0032] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] Reference Figures 1 to 6 As shown, this embodiment provides a hinge structure for eyeglasses, including a first connector 10, a second connector 20, and a third connector 30. The first connector 10 is used to connect to a frame 100. The second connector 20 is assembled on the first connector 10 and has a hinge notch 201 facing away from the frame 100. Specifically, the side facing the frame 100 is defined as the inner side, and the side facing away from the frame 100 is defined as the outer side. The hinge notch 201 is formed on the outer side of the second connector 20.

[0036] The third connector 30 is used to connect the temple 200 and has a hinge protrusion 31. The hinge protrusion 31 of the third connector 30 is rotatably fitted into the hinge notch 201 of the second connector 20. The first connector 10 also abuts against the third connector 30 to prevent the hinge protrusion 31 of the third connector 30 from disengaging from the hinge notch 201. In this way, the hinge protrusion 31 can be well restrained, realizing the hinge movement.

[0037] This embodiment also provides a pair of glasses, such as Figure 1 As shown, the glasses include a frame 100, temples 200, and the hinge structure of the glasses described above; the first connector 10 connects to the frame 100; the third connector 30 connects to the temples 200. When the temples 200 are unfolded from the folded state, they swing outwards. When they reach the unfolded state, the third connector 30 is blocked by the first connector 10, thereby maintaining their position.

[0038] The hinge structure of the eyeglasses provided in this application has the following beneficial effects:

[0039] 1. The third connector 30 is rotatably fitted into the hinge notch 201 of the second connector 20 via the hinge protrusion 31 and is abutted and restricted by the first connector 10, so that the temple 200 connected to the third connector 30 can be folded and unfolded normally, realizing screwless hinge, which can effectively avoid the problems of easy stripping and loosening during assembly caused by screw hinge, and effectively improve assembly efficiency and usage stability.

[0040] 2. The screwless hinge structure allows the first connector 10, the second connector 20, and the third connector 30 to be made of lightweight materials (such as plastics), which can effectively reduce weight and achieve lightweighting.

[0041] 3. The first connector 10 restricts the hinge protrusion 31 within the hinge notch 201 by abutting. When the temple 200 is in the unfolded state (at which time the third connector 30 is blocked by the first connector 10), the temple 200 will continue to unfold under external force or when worn on a wider head, thereby forcing the first connector 10 to change shape and have a certain outward expansion space. In this way, the pressure can be effectively released and the wearing is more comfortable.

[0042] Furthermore, in this embodiment, as Figure 4 , Figure 5 As shown, the second connector 20 has two spaced-apart connecting pieces 22. The hinge notch 201 is formed on both connecting pieces 22, meaning both connecting pieces 22 have a hinge notch 201. The third connector 30 has two coaxially arranged hinge protrusions 31, which are rotatably fitted into the hinge notches 201 of the two connecting pieces 22. This arrangement makes the movement of the temple 200 more stable.

[0043] For more specific details, refer to Figure 6 As shown, the third connecting member 30 has a cross-shaped structure, including a horizontally arranged horizontal bar and a vertically arranged vertical bar. The first end 321 of the horizontal bar is connected to the temple 200, and the two ends of the vertical bar form two coaxially arranged hinged protrusions 31. The horizontal bar is located in the gap between the two connecting pieces 22. When the temple 200 is folded inward from the unfolded state, an external force needs to be applied to the temple 200. During the folding process, the second end 322 of the horizontal bar abuts against the first connecting piece 10 and forces the first connecting piece 10 to deform outward, while the first end 321 of the horizontal bar of the third connecting member 30 is located between the two connecting pieces 22 to achieve unobstructed swinging.

[0044] More specifically, the end face of the second end 322 of the crossbar is flat. Thus, when the temple 200 is folded, the end face of the second end 322 of the crossbar smoothly abuts against the first connecting member 10, which can well maintain the folded state.

[0045] Specifically, in this embodiment, the third connector 30 and the temple 200 are integrally connected, and can be integrally formed by means of mold injection molding, etc., which makes the structure simple to prepare.

[0046] Furthermore, the first connector 10 is integrally extended from the frame 100. In this embodiment, the frame 100 is formed by two frame lines, and the first connector 10 is formed by the ends of the two frame lines side by side.

[0047] Specifically, the first connector 10 has an "L"-shaped structure, including a first part 11 connecting to the frame 100 and a second part 12 connecting to the first part 11 and arranged at an angle to it. The second connector 20 includes two spaced-apart connecting pieces 22 and a fixing piece 21 connecting the two connecting pieces 22. The two connecting pieces 22 and the fixing piece 21 form a U-shaped groove. The first end of the connecting piece 22 forms a limiting step 202 with the fixing piece 21. The second end of the connecting piece 22 extends outward at an angle to form an extension arm 23. The hinge notch 201 is formed on the extension arm 23. The first part 11 of the first connector 10 passes through the U-shaped groove of the second connector 20. The limiting step 202 is engaged with the frame 100. The second part 12 of the first connector 10 corresponds to the hinge notch 201 and abuts against the third connector 30. In this way, the third connector 30 can be prevented from disengaging from the hinge notch 201, and the first connector 10 and the second connector 20 can be fixed. No other fasteners are needed to assist in the assembly. The structure is simple and the design is ingenious.

[0048] Example 2

[0049] Reference Figures 7 to 12 As shown, this embodiment provides a hinge structure for eyeglasses, including a first connector 10, a second connector 20, and a third connector 30. The first connector 10 is used to connect to a frame 100. The second connector 20 is assembled on the first connector 10 and has a hinge notch 201 facing away from the frame 100. Specifically, the side facing the frame 100 is defined as the inner side, and the side facing away from the frame 100 is defined as the outer side. The hinge notch 201 is formed on the outer side of the second connector 20.

[0050] The third connector 30 is used to connect the temple 200 and has a hinge protrusion 31. The hinge protrusion 31 of the third connector 30 is rotatably fitted into the hinge notch 201 of the second connector 20. The first connector 10 also abuts against the third connector 30 to prevent the hinge protrusion 31 of the third connector 30 from disengaging from the hinge notch 201. In this way, the hinge protrusion 31 can be well restrained, realizing the hinge movement.

[0051] This embodiment also provides a pair of glasses, such as Figure 7As shown, the glasses include a frame 100, temples 200, and the hinge structure of the glasses described above; the first connector 10 connects to the frame 100; the third connector 30 connects to the temples 200. When the temples 200 are unfolded from the folded state, they swing outwards. When they reach the unfolded state, the third connector 30 is blocked by the first connector 10, thereby maintaining their position.

[0052] The hinge structure of the eyeglasses provided in this application has the following beneficial effects:

[0053] 1. The third connector 30 is rotatably fitted into the hinge notch 201 of the second connector 20 via the hinge protrusion 31 and is abutted and restricted by the first connector 10, so that the temple 200 connected to the third connector 30 can be folded and unfolded normally, realizing screwless hinge, which can effectively avoid the problems of easy stripping and loosening during assembly caused by screw hinge, and effectively improve assembly efficiency and usage stability.

[0054] 2. The screwless hinge structure allows the first connector 10, the second connector 20, and the third connector 30 to be made of lightweight materials (such as plastics), which can effectively reduce weight and achieve lightweighting.

[0055] 3. The first connector 10 restricts the hinge protrusion 31 within the hinge notch 201 by abutting. When the temple 200 is in the unfolded state (at which time the third connector 30 is blocked by the first connector 10), the temple 200 will continue to unfold under external force or when worn on a wider head, thereby forcing the first connector 10 to change shape and have a certain outward expansion space. In this way, the pressure can be effectively released and the wearing is more comfortable.

[0056] Furthermore, in this embodiment, as Figure 10 , Figure 11 As shown, the second connector 20 has two spaced-apart connecting pieces 22. The hinge notch 201 is formed on both connecting pieces 22, meaning both connecting pieces 22 have a hinge notch 201. The third connector 30 has two coaxially arranged hinge protrusions 31, which are rotatably fitted into the hinge notches 201 of the two connecting pieces 22. This arrangement makes the movement of the temple 200 more stable.

[0057] For more specific details, refer to Figure 12As shown, the third connecting member 30 has a cross-shaped structure, including a horizontally arranged horizontal bar and a vertically arranged vertical bar. The first end 321 of the horizontal bar is connected to the temple 200, and the two ends of the vertical bar form two coaxially arranged hinged protrusions 31. The horizontal bar is located in the gap between the two connecting pieces 22. When the temple 200 is folded inward from the unfolded state, an external force needs to be applied to the temple 200. During the folding process, the second end 322 of the horizontal bar abuts against the first connecting piece 10 and forces the first connecting piece 10 to deform outward, while the first end 321 of the horizontal bar of the third connecting member 30 is located between the two connecting pieces 22 to achieve unobstructed swinging.

[0058] More specifically, the end face of the second end 322 of the crossbar is flat. Thus, when the temple 200 is folded, the end face of the second end 322 of the crossbar smoothly abuts against the first connecting member 10, which can well maintain the folded state.

[0059] Specifically, in this embodiment, the third connector 30 and the temple 200 are integrally connected, and can be integrally formed by means of mold injection molding, etc., which makes the structure simple to prepare.

[0060] Furthermore, the first connector 10 is detachably mounted on the frame, achieving a detachable connection.

[0061] Specifically, the first connector 10 has an "L"-shaped structure, including a first part 11 connecting to the frame 100 and a second part 12 connecting to the first part 11 and arranged at an angle to it. The first part 11 is detachably and fixedly inserted into the frame 100, that is, the frame 100 is provided with a slot 110, and the first part 11 is detachably and fixedly inserted into the slot 110 of the frame 100. In this way, the first connector 10 can be installed and removed from the frame 100 by plugging and unplugging. The structure is simple and easy to implement. Of course, the detachable fixing method is not limited to this. The second part 12 connects to the second connector 20 and abuts against the third connector 30.

[0062] More specifically, the second connector 20 includes two spaced-apart connecting pieces 22 and a fixing piece 21 connecting the two connecting pieces 22. The fixing piece 22 is located between the first end and the second end of the connecting pieces 22. The first end of the connecting piece 22 has a first limiting step 203. The hinge notch 201 is formed on the outer side wall of the connecting piece 22 near the second end. The outer side wall of the second part 12 of the first connector 10 has a second limiting step 121. The second part 12 passes between the two connecting pieces 22. The first limiting step 203 of the connecting piece 22 is engaged with the inner side wall of the second part 12. The second limiting step 121 of the second part 12 is engaged with the fixing piece 21. The outer end of the second part 12 abuts against the third connector 30. In this way, the third connector 30 can be prevented from disengaging from the hinge notch 201, and the first connector 10 and the second connecting piece 20 can be fixed. No other fasteners are needed for assembly. The structure is simple and the design is ingenious.

[0063] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
