Description

Technical Field

[0001] This invention relates to the technical field of eyeglasses, and more specifically, to a folding eyeglass frame and eyeglasses. Background Technology

[0002] Eyeglasses are a combination of lenses and frames used to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct various vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, strabismus, and amblyopia. They can be categorized into 15 types, including prescription glasses, farsighted glasses, reading glasses, astigmatism glasses, non-prescription glasses, computer glasses, protective goggles, swimming goggles, night vision goggles, gaming glasses, e-sports goggles, windproof goggles, sunglasses, toy glasses, and more, providing various forms of eye protection. Specialized glasses are also available for viewing 3D or virtual reality images.

[0003] Folding glasses are also a type of eyeglasses. They typically consist of a left and a right frame that can move relative to each other. They usually fold from the bridge of the frame, so that the temples of the left and right frames move closer to each other until the frames of the left and right frames fold together.

[0004] During their research, the inventors discovered that existing folding glasses, due to the need for frequent folding and unfolding, are prone to wear and loosening at the hinge between the left and right frames, as both parts are made of relatively hard materials and are rigidly connected, resulting in an unstable connection. Summary of the Invention

[0005] The purpose of this invention is to provide a folding eyeglass frame that addresses the problems existing in the prior art, offering corresponding solutions and possessing advantages such as structural stability, aesthetic appeal, durability, resistance to wobbling, and ease of use.

[0006] The present invention also aims to provide a pair of glasses that can provide corresponding solutions to the problems existing in the prior art, and has the advantages of good folding effect and convenient use.

[0007] The embodiments of the present invention are implemented as follows:

[0008] In a first aspect, embodiments of this application provide a folding eyeglass frame, including an eyeglass frame, a temple head section, and a temple tail section that are hinged sequentially, and also including a connecting hinge and a hinge insert. The connecting hinge is provided with a limiting groove, and a round shaft is provided in the limiting groove. Limiting blocks that connect to the groove wall are provided at both ends of the round shaft. One side of the hinge insert is fixedly connected to the eyeglass frame, and the other side of the hinge insert is provided with a limiting support bar that abuts against the limiting block and a connecting support bar located between the two limiting supports. The connecting support bar is provided with a round groove for accommodating the round shaft.

[0009] In some embodiments of the present invention, the bottom of the limiting groove is provided with an opening corresponding to the circular shaft.

[0010] In some embodiments of the present invention, a first strip groove for increasing deformation is provided between the limiting support and the connecting support.

[0011] In some embodiments of the present invention, the aforementioned limiting groove is provided at one end of the connecting hinge, the other end of the connecting hinge is provided with a socket, and the temple head is provided with a plug that extends into the socket.

[0012] In some embodiments of the present invention, the plug includes an elastic strip, a wedge-shaped block is provided on the outer side of the elastic strip, and a limiting hole adapted to the wedge-shaped block is provided on the inner wall of the socket.

[0013] In some embodiments of the present invention, the plug is provided with a second groove that increases the elastic strip deformation.

[0014] In some embodiments of the present invention, the temple head section and the temple tail section are connected by the connecting hinge. The temple head section is connected to the hinge insert near the temple tail section, and the temple tail section is also connected to the hinge insert near the temple head section. The two hinge inserts are respectively inserted into the limiting grooves at both ends of the connecting hinge.

[0015] In some embodiments of the present invention, the above-mentioned eyeglass frame includes a left frame and a right frame, both of which are provided with barbed springs, and the barbed springs are provided with nose pads.

[0016] In some embodiments of the present invention, the temple section of the above-mentioned mirror is provided with an arc-shaped elastic support.

[0017] Secondly, embodiments of this application provide an eyeglass, including the aforementioned folding eyeglass frame, wherein lenses are installed within the eyeglass frame.

[0018] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0019] In a first aspect, this application provides a folding eyeglass frame, mainly comprising five parts: an eyeglass frame, temple head sections, temple tail sections, connecting hinges, and hinge inserts. The eyeglass frame is divided into a left frame and a right frame, providing mounting positions for the lenses and fixing them in front of the eyes. The temple head sections connect to the eyeglass frame; the temple tail sections rest on the ears; and the connecting hinges and hinge inserts achieve a stable hinge connection between the two parts. In this embodiment, the eyeglass frame, temple head sections, and temple tail sections can be hinged together using existing technology. The left and right frames are hinged together using connecting hinges and hinge inserts, or all three sections can be hinged together using connecting hinges and hinge inserts. The connecting hinge is roughly a cuboid block with limiting grooves on both its left and right sides. Each limiting groove has upper and lower walls and a rear bottom. A limiting block is installed at each end of the cylinder. The upper limiting block is fixedly connected to the upper wall of the limiting groove, and the lower limiting block is fixedly connected to the lower wall of the limiting groove. Gaps are left between the limiting blocks, the cylinder, and the bottom of the limiting grooves to facilitate the insertion of the hinge insert. A hinge insert is fixed to the right side of the left frame and the left side of the right frame, inserted from both sides of the connecting hinge. Each hinge insert includes two horizontally parallel limiting supports and a connecting support. The connecting support is located between the two limiting supports, aligned with the two limiting blocks, and aligned with the circular shaft between the connecting support and the limiting blocks. The end of the connecting support is bent to form a circular groove to accommodate the circular shaft, allowing the connecting support to rotate around the cylinder. The hinged insert can be made of a metal material with a certain degree of elasticity.

[0020] During installation, the hinge insert is inserted into the gap between the cylinder and the bottom of the limiting groove. The connecting strip is secured to the cylinder, and the limiting strip is secured between the limiting block and the bottom of the limiting groove. In actual use, because the connecting strip and the cylinder are secured, pulling the limiting strip against the rear end face of the limiting block prevents wobbling. Due to the edges of the limiting block, the limiting strip against its rear end face prevents the connecting hinge and hinge insert from automatically folding after extension. The left and right frames remain open, making it easy to remove the glasses and put them back on without needing to adjust them. When folding for storage, the left and right frames are bent, forcing the connecting strip to rotate around the cylinder. Because the hinge insert has a certain degree of elasticity, it will not break. After the limiting strip rotates 90°, it is pressed against the other side wall of the limiting block, preventing the connecting hinge and hinge insert from automatically extending after folding, making it convenient for storage and use. In this embodiment, the folding eyeglass frame has a certain damping feel when unfolded or folded due to the cooperation of the limiting support and the limiting block, making the experience more comfortable.

[0021] Secondly, this application provides a pair of eyeglasses, which consist of the aforementioned folding eyeglass frame, with lenses installed within the frame. This embodiment offers the advantages of good folding performance and ease of use.

[0022] Furthermore, currently, neither domestically nor internationally, anyone in the eyewear industry has used ceramics to make eyeglass hinges, bridges, or joints. In contrast, the connecting hinges of the eyeglasses in this embodiment are all made of ceramic or special metal materials, such as powder metallurgy stainless steel or liquid metal, ensuring the hardness and wear resistance of the folding joints of the product of this invention, thereby greatly extending the service life of the product and further highlighting the uniqueness and value of the embodiment of this invention.

[0040] Example 1

[0041] Please refer to Figures 1 to 7 The image shows an embodiment of the present invention that provides a folding eyeglass frame, the specific structure of which is as follows.

[0042] This application provides a folding eyeglass frame, including an eyeglass frame 1, a temple head section 2, and a temple tail section 3, which are hinged sequentially. It also includes a connecting hinge 4 and a hinge insert 5. The connecting hinge 4 has a limiting groove 401, within which a round shaft 402 is disposed. Limiting blocks 403, which connect to the groove wall of the limiting groove 401, are provided at both ends of the round shaft 402. One side of the hinge insert 5 is fixedly connected to the eyeglass frame 1, and the other side of the hinge insert 5 has a limiting support bar 501 that abuts against the limiting block 403 and a connecting support bar 502 located between the two limiting supports 501. The connecting support bar 502 has a circular groove 5021 for accommodating the round shaft 402. Figure 1 As shown, the folding eyeglass frame of this invention mainly comprises five parts: an eyeglass frame 1, a temple head section 2, a temple tail section 3, a connecting hinge 4, and a hinge insert 5. The eyeglass frame 1 is divided into a left frame 101 and a right frame 102, providing mounting positions for the lenses and fixing them in front of the eyes. The temple head section 2 is used to connect to the eyeglass frame 1. The temple tail section 3 is used to rest on the ears. The connecting hinge 4 and the hinge insert 5 are used to achieve a stable hinge connection between the two parts.

[0043] It should be noted that, in this embodiment, the eyeglass frame 1, the temple head section 2, and the temple tail section 3 can be hinged together using existing technology. The left frame 101 and the right frame 102 are hinged together by connecting hinge 4 and hinge insert 5 (i.e., the connecting hinge 4 is equivalent to the center beam hinge). Alternatively, the eyeglass frame 1, the temple head section 2, and the temple tail section 3 can all be hinged together by connecting hinge 4 and hinge insert 5.

[0044] Combination Figure 1 and Figure 2 As shown, the connecting hinge 4 is roughly a cuboid block with limiting grooves 401 on both its left and right sides. Each limiting groove 401 has upper and lower groove walls and a rear groove bottom. A limiting block 403 is installed at each end of the cylinder. The upper limiting block 403 is fixedly connected to the upper groove wall of the limiting groove 401, and the lower limiting block 403 is fixedly connected to the lower groove wall of the limiting groove 401. Gaps are left between the limiting blocks 403, the cylinder, and the groove bottom of the limiting groove 401 to facilitate the insertion of the hinge insert 5. A hinge insert 5 is fixed to the right side of the left mirror frame 101 and the left side of the right mirror frame 102. The two hinge inserts 5 are inserted from both sides of the connecting hinge 4. The hinge insert 5 includes two horizontally parallel limiting supports 501 and a connecting support 502. The connecting support 502 is located between the two limiting supports 501. The two limiting supports 501 are aligned with two limiting blocks 403, and the connecting support 502 is aligned with the circular shaft 402 between the limiting blocks 403. The end of the connecting support 502 is bent to form a circular groove 5021, which is used to accommodate the circular shaft 402, allowing the connecting support 502 to rotate around the cylinder. The hinge insert 5 can be made of a metal material with a certain degree of elasticity, such as powder metallurgy stainless steel or liquid metal.

[0045] During installation, the hinge insert 5 is inserted into the gap between the cylinder and the bottom of the limiting groove 401 along the limiting groove 401. The connecting support 502 is secured to the cylinder, and the limiting support 501 is secured between the limiting block 403 and the bottom of the limiting groove 401. In actual use, because the connecting support 502 and the cylinder are secured, pulling the limiting support 501 against the rear end face of the limiting block 403 prevents wobbling. Due to the edges of the limiting block 403, the limiting support 501 against the rear end face of the limiting block 403 prevents the connecting hinge 4 and the hinge insert 5 from automatically folding after extension. The left frame 101 and the right frame 102 remain in an open shape, making it convenient for people to rub their eyes after taking off their glasses and put them back on without needing to adjust them. When folding for storage, the connecting rod 502 is used to fold the left frame 101 and right frame 102, forcing the connecting rod 502 to rotate around the cylinder. Because the hinge insert 5 has a certain degree of elasticity, it will not break. After the limiting rod 501 rotates 90°, it adheres tightly to the other side wall of the limiting block 403, preventing the connecting hinge 4 and hinge insert 5 from automatically extending after folding, making it convenient for storage and use. In this embodiment, the folding eyeglass frame provides a certain degree of damping during unfolding or folding due to the cooperation of the limiting rod 501 and the limiting block 403, resulting in a more comfortable experience.

[0046] In some embodiments of this example, the bottom of the limiting groove 401 is provided with an opening 405 corresponding to the circular shaft 402. Combined with... Figure 1 or Figure 4 or Figure 6 As shown, a square opening 405 penetrates the bottom of the groove behind the limiting groove 401, and the opening 405 is positioned directly opposite the circular shaft 402. Through the technical solution of this embodiment, since the limiting groove 401 has an opening 405, the limiting support bar 501 will not be blocked or restricted by the bottom of the limiting groove 401 during rotation, making the rotation of the connecting hinge 4 and the hinge insert 5 smoother.

[0047] In some embodiments of this example, a first strip groove 503 for increasing deformation is provided between the limiting support 501 and the connecting support 502. Figure 1 and Figure 2As shown, a hinge insert 5 has two first strip grooves 503, which are formed between the limiting support 501 and the connecting support 502. In this embodiment, the limiting support 501, the first strip grooves 503, and the connecting support 502 are parallel in sequence. When the hinge insert 5 is inserted into the connecting hinge 4, the limiting support 501 is inserted between the limiting block 403 and the bottom of the limiting groove 401. At this time, due to the restriction of the upper and lower groove walls of the limiting groove 401, the upper limiting support 501 is pressed downwards, and the lower limiting support 501 is pressed upwards. Due to the presence of the first strip groove 503, the limiting supports 501 on both sides deflect relative to each other. After deflection, the limiting supports 501, under their own elasticity, press firmly against the upper and lower groove walls, preventing the hinge insert 5 from wobbling up and down, making it more comfortable to use.

[0048] In some embodiments of this example, the limiting groove 401 is provided at one end of the connecting hinge 4, and the other end of the connecting hinge 4 is provided with a socket 404. The temple head section 2 is provided with a plug 201 that extends into the socket 404. Figure 1 and Figure 3 As shown, in this embodiment, the eyeglass frame 1 and the temple head section 2 are connected by a connecting hinge 4 (i.e., the connecting hinge 4 is equivalent to a plinth hinge). A hinge insert 5 is installed on the right side of the left frame 101 and the left side of the right frame 102. Each of the two hinge inserts 5 is connected to a connecting hinge 4. One end of the connecting hinge 4 has a limiting groove 401 that is hinged to it. The other end of the connecting hinge 4 has a square inlet 404 at its center. A plug 201 is installed on the end of the temple head section 2 near the eyeglass frame 1. The plug 201 is inserted into the inlet 404 for fixed installation. Through the technical solution of this embodiment, the plug 201 is inserted into the inlet 404, connecting the temple head section 2 and the connecting hinge 4. Because the cross-section of the inlet 404 is square, rotation does not occur after connection, resulting in a good connection effect.

[0049] In some embodiments of this example, the plug 201 includes an elastic strip 2011, a wedge-shaped block 2012 is provided on the outer side of the elastic strip 2011, and a limiting hole 4041 adapted to the wedge-shaped block 2012 is provided on the inner wall of the socket 404. Figure 1 and Figure 3As shown, an elastic strip 2011 is installed on each of the upper and lower sides of the plug 201, and the elastic strip 2011 can deflect vertically. A wedge block 2012 is fixed to the outer side of the front end of the elastic strip 2011, and a limiting hole 4041 is opened on the upper and lower inner walls of the socket 404. Through the technical solution of this embodiment, during the process of inserting the plug 201 into the socket 404, the wedge block 2012 slides along the inner wall of the socket 404, allowing the wedge block 2012 to slide to the position of the limiting hole 4041, where it will be engaged. The vertical surface of the rear side of the wedge block 2012 abuts against the side wall of the limiting hole 4041, preventing the plug 201 from being pulled out of the socket 404, thus providing a better fixing effect.

[0050] In some embodiments of this example, the plug 201 is provided with a second strip groove 2013 to increase the deformation of the elastic strip 2011. Combined with Figure 1 and Figure 3 As shown, a plug 201 has two second strip-shaped grooves 2013, which facilitate the deformation and movement of the two elastic strips 2011. Through the technical solution of this embodiment, when the plug 201 is inserted into the socket 404, the elastic strips 2011 are also inserted into the socket 404. At this time, due to the restriction of the wedge block 2012 by the upper and lower side walls of the socket 404, the upper elastic strip 2011 is pressed downwards and the lower elastic strip 2011 is pressed upwards. Due to the presence of the second strip-shaped grooves 2013, the elastic strips 2011 on both sides deflect towards the center. When the wedge block 2012 moves to align with the limiting hole 4041, the elastic strips 2011, under their own elasticity, push the wedge block 2012 into the limiting hole 4041, automatically engaging, resulting in good performance.

[0051] In some embodiments of this example, the temple head section 2 and temple tail section 3 are connected by a connecting hinge 4. A hinge insert 5 is connected to the end of the temple head section 2 near the temple tail section 3, and a hinge insert 5 is also connected to the end of the temple tail section 3 near the temple head section 2. The two hinge inserts 5 are respectively inserted into the limiting grooves 401 at both ends of the connecting hinge 4. Figure 1 and Figure 4 As shown, in some embodiments of this example, the temple head section 2 and temple tail section 3 are also hinged via a connecting hinge 4 (i.e., the connecting hinge 4 is equivalent to a temple hinge). A hinge insert 5 is fixedly installed at one end of the temple head section 2 near the temple tail section 3, and a hinge insert 5 is also fixedly installed at one end of the temple tail section 3 near the temple head section 2. The connecting hinge 4 is installed between the two hinge inserts 5, and the two hinge inserts 5 extend into the limiting grooves 401 on both sides of the connecting hinge 4, thus achieving the hinge connection. Through the technical solution of this embodiment, combined with... Figure 1 and Figure 7As shown, the temple head section 2 and temple tail section 3 can be folded. Combined with the folding of the left frame 101 and the right frame 102, the folding effect of the folding eyeglass frame is further improved, and the folded size is smaller and more convenient to carry.

[0052] In some embodiments of this example, the eyeglass frame 1 includes a left frame 101 and a right frame 102, both of which are provided with barbed springs 103, and each barbed spring 103 is provided with a nose pad 104. Combined with... Figure 1 As shown, the eyeglass frame 1 consists of a left frame 101 and a right frame 102 connected by a connecting hinge 4. A barbed spring 103 is installed on the right side of the left frame 101 and the left side of the right frame 102. A nose pad 104 is embedded in the barbed spring 103. Through the technical solution of this embodiment, the contact area between the nose pad 104 and the bridge of the nose is large, resulting in less pressure and facilitating the placement of the folding eyeglass frame on the bridge of the nose, thus improving the user experience.

[0053] In some embodiments of this example, the temple tail section 3 is provided with a curved elastic support. Combined with... Figure 1 As shown, the temple section 3 uses an arc-shaped elastic support, which makes it easier to rest on the ear and provides a better viewing experience.

[0054] Example 2

[0055] Please refer to Figure 1 This application also provides a pair of eyeglasses, which consist of the aforementioned folding eyeglass frame, with lenses installed within the frame 1 of the folding eyeglass frame. The technical solution of this embodiment has the advantages of good folding effect and ease of use.

[0056] In summary, embodiments of the present invention provide a folding eyeglass frame, comprising an eyeglass frame 1, a temple head section 2, and a temple tail section 3, which are hinged sequentially. It also includes a connecting hinge 4 and a hinge insert 5. The connecting hinge 4 has a limiting groove 401, within which a round shaft 402 is disposed. Limiting blocks 403, which connect to the groove walls of the limiting groove 401, are provided at both ends of the round shaft 402. One side of the hinge insert 5 is fixedly connected to the eyeglass frame 1. The other side of the hinge insert 5 has a limiting support bar 501 that abuts against the limiting block 403 and a connecting support bar 502 located between the two limiting support bars 501. The connecting support bar 502 has a circular groove 5021 for accommodating the round shaft 402. This design offers advantages such as structural stability, reduced wobbling, and greater ease of use. Embodiments of the present invention provide eyeglasses with advantages of good folding effect and convenient use.
