Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an easy-assembly structure for rimless eyeglasses. Background Technology

[0002] Eyeglasses are a combination of lenses and frames, used to improve vision, protect the eyes, or as a fashion accessory. The frame consists of a frame and temples, with the lenses housed within the frame. The frame and temples are connected by a hinge structure, allowing the temples to unfold or fold relative to the frame, thus meeting the needs of wearing, use, and storage.

[0003] Based on traditional eyeglasses, rimless glasses have been introduced to the market, eliminating the need for a frame structure. Rimless glasses use screws and nuts to fix the bridge and post to the lenses, thus fulfilling their functional purpose.

[0004] However, the problem with rimless glasses is that after a period of wear, the screws and nuts at the joints often become loose, causing problems with the connection between the lens and the bridge and post, resulting in discomfort for the wearer. Therefore, it is necessary to frequently tighten the screws and nuts with tools, which is more troublesome in terms of assembly and use.

[0005] Moreover, as consumers pursue fashionable elements in eyewear, they often need to match different eyewear to suit their environment and clothing. However, purchasing multiple pairs of eyewear is costly and inconvenient to carry. Therefore, solutions have emerged that allow carrying accessories and rotating them with the lenses.

[0006] Traditional rimless glasses use a screw-mounted structure, requiring tools such as screwdrivers for disassembly. This process is cumbersome and requires the necessary tools, making it difficult for consumers to quickly disassemble and reassemble. Moreover, with repeated disassembly and reassembly, the lens mounting area is prone to wear and tear.

[0007] Therefore, the assembly structure of rimless glasses needs to be improved to allow users to easily assemble and disassemble the rimless glasses accessories, with a stable and reliable connection, and to prevent damage to the lens mounting parts during the assembly and disassembly process through structural design. Utility Model Content

[0008] To address the shortcomings of the aforementioned technologies, this invention provides an easy-to-assemble structure for frameless eyeglasses.

[0009] A further feature of this utility model is an easy-assembly structure for frameless glasses, comprising a pair of lenses, a nose bridge, and a post. The lenses are provided with a first mounting slot and a second mounting slot respectively corresponding to the mounting positions of the nose bridge and the post. The frameless glasses also include a connector that can be detachably installed in the first mounting slot and the second mounting slot, and the connector is provided with an assembly slot at its center.

[0010] The nose bridge is disposed between a pair of lenses. Each end of the nose bridge has a first snap-fit ​​portion extending to the first mounting slot on both sides. The outline of the first snap-fit ​​portion is adapted to the outline of the mounting slot and is detachably and elastically snapped into the mounting slot at the first mounting slot. The post head is provided with a second snap-fit ​​portion extending to the second mounting slot. The outline of the second snap-fit ​​portion is adapted to the outline of the mounting slot and is detachably and elastically snapped into the mounting slot at the second mounting slot.

[0011] A further feature of this invention is that both the first and second snap-fit ​​parts are provided with a relief groove along the insertion direction. The relief groove is located in the middle section of the first and second snap-fit ​​parts. On the two end faces of the first and second snap-fit ​​parts opposite to the relief groove, there are snap-fit ​​teeth grooves. The inner circumferential surface of the connecting member assembly groove is provided with protruding teeth that are adapted to and engage with the snap-fit ​​teeth grooves.

[0012] Further features of this invention: The lens includes a first end face facing the eye and a second end face away from the eye. The first mounting groove, the second mounting groove, and the assembly groove are all arranged along the direction of penetrating the first end face and the second end face. The connector is provided with a limiting flange that abuts against the first end face. The outer peripheral surface of the connector is in frictional connection with the inner walls of the first mounting groove and the second mounting groove. The nose bridge and the post are arranged on one side of the second end face.

[0013] A further feature of this invention is that the nose bridge frame and the pile head cover the first mounting slot, the second mounting slot, or the connector.

[0014] A further feature of this invention is that the connector is made of rubber.

[0015] A further feature of this invention is that the connector is made of plastic material.

[0016] A further feature of this invention is that the connector is made of metal.

[0017] A further feature of this invention is that the connector is made of composite material.

[0018] A further feature of this invention is that a support member made of metal, plastic, or composite material is provided at the assembly slot of the connector, and the protruding teeth are provided on the support member.

[0019] The beneficial effects of this utility model are as follows: First, by designing the connector, the nose bridge and the head piece are prevented from being directly installed and disassembled with the lens, and the connector is used to bear the wear and tear of the contact during installation and disassembly instead of the lens.

[0020] 2. The first and second locking parts of the nose bridge and headpiece design utilize the gap of the recessed through groove. When inserted into the mounting through groove and squeezed by the raised teeth, they can narrow and undergo elastic deformation to pass through. After entering the mounting through groove, the locking teeth and the raised teeth engage to obtain space for deformation recovery. The first and second locking parts recover their deformation, and the raised teeth act as a limit to the exit direction, thereby completing the stable connection between the nose bridge, headpiece and lens.

[0021] When the user needs to disassemble, they only need to pull out the nose bridge and the head piece by hand in the direction of withdrawal. With the correct direction and a certain amount of external force, the first and second locking parts will be forced to narrow again and undergo elastic deformation to be pulled out.

[0022] 3. The friction connection between the connector and the lens through groove facilitates installation and replacement. The limiting flange is set on the first end face of the lens near the eye. When the nose bridge and post are pulled out on the other side, the limiting flange abuts against the lens to prevent the connector from being pulled out. With the nose bridge and post covering the second end face of the lens, the connector is hidden, making the frameless glasses look more integrated and beautiful when viewed by outsiders.

[0032] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-6 As shown,

[0033] An easy-assembly structure for rimless glasses includes a pair of lenses 1, a nose bridge 2, and post pieces 3 (paired at both ends of the lenses, each with its own hinged temple). The lenses 1 are provided with a first mounting slot 11 and a second mounting slot 12 corresponding to the mounting positions of the nose bridge 2 and post pieces 3. The rimless glasses also include a connector 4 that is detachably installed in the first mounting slot 11 and the second mounting slot 12. The connector 4 has an assembly slot 41 at its center.

[0034] The nose bridge 2 is disposed between a pair of lenses 1. Each end of the nose bridge 2 is provided with a first snap-fit ​​portion 21 extending to the first mounting slot 11 on both sides. The outline of the first snap-fit ​​portion 21 is adapted to the outline of the mounting slot 41 and is detachably and elastically snapped into the mounting slot 41 at the first mounting slot. The post head 3 is provided with a second snap-fit ​​portion 31 extending to the second mounting slot 12. The outline of the second snap-fit ​​portion 31 is adapted to the outline of the mounting slot 41 and is detachably and elastically snapped into the mounting slot 41 at the second mounting slot.

[0035] The cross-sectional shape of the first mounting through groove 11, the second mounting through groove 12, and the assembly through groove 41 can adopt conventional geometric shapes, such as round holes and square holes. The elongated holes shown in Embodiments 1 and 2 of this application are designed to facilitate the mirror setting of the protruding teeth 42, the snap-fit ​​teeth 23, and the insertion and mating.

[0036] The first mounting slot 11, the second mounting slot 12, and the assembly slot 41 can be designed according to the contours of the nose bridge component and the pile head component 3. For example, in the embodiment of this application, if the nose bridge component and the pile head component 3 are relatively narrow, an elongated hole is designed to be horizontally parallel to it in order to correspond to the narrow side, or a matching rectangular hole or other form can be used for adaptation; and if Figure 5 In Embodiment 2, the wider nose bridge component and the pile head component 3 can be designed with an elongated oval hole in a vertical position to fit it, or a square hole of a suitable size, etc.

[0037] Both the first snap-fit ​​portion 21 and the second snap-fit ​​portion 31 are provided with a relief groove 22 along the insertion direction. The relief groove 22 is located in the middle section of the first snap-fit ​​portion 21 and the second snap-fit ​​portion 31. Both the first snap-fit ​​portion 21 and the second snap-fit ​​portion 31 are provided with snap-fit ​​tooth grooves 23 on their two end faces opposite to the relief groove 22. The inner circumferential surface of the mounting groove 41 of the connector 4 is provided with a protruding tooth portion 42 that is adapted to engage with the snap-fit ​​tooth groove 23.

[0038] The lens 1 includes a first end face facing the eye and a second end face away from the eye. The first mounting groove 11, the second mounting groove 12, and the assembly groove 41 are all arranged along the direction of penetrating the first end face and the second end face. The connector 4 is provided with a limiting flange 43 that abuts against the first end face. The outer peripheral surface of the connector 4 is in frictional connection with the inner wall of the first mounting groove 11 and the second mounting groove 12. The nose bridge 2 and the post head 3 are arranged on one side of the second end face.

[0039] The nose bridge frame 2 and the pile head 3 cover the first mounting slot 11, the second mounting slot 12, or the connector 4.

[0040] The connector 4 is made of rubber or other elastomers.

[0041] The connector 4 is made of plastic material. For example, it can be formed from molded plastics (such as acrylonitrile butadiene styrene (ABS), ABS / PC blends, high-density polyethylene (HDPA), thermoplastic polyester resin (PET), nylon, and other materials). Alternatively, it can be formed by 3D printing additive manufacturing.

[0042] The connector 4 is made of metal.

[0043] The connector 4 is made of a composite material (e.g., fiber-reinforced or laminated material).

[0044] The connector assembly slot is provided with a support member made of metal, plastic or composite material, and the protruding teeth are provided on the support member.

[0045] The design of connector 4 avoids the nose bridge 2 and the head piece 3 from being directly installed and disassembled with the lens 1, and the connector 4 replaces the lens 1 to bear the wear and tear of the disassembly and assembly contact.

[0046] 2. The first and second locking parts 31 of the nose bridge frame 2 and the headpiece 3 are designed to utilize the gap of the recessed through groove 22 so that when it is inserted into the installation through groove and squeezed by the protruding teeth 42, it can narrow and elastically deform to pass through. After entering the installation through groove, the locking teeth 23 and the protruding teeth 42 are joined together to obtain space for deformation recovery. The first and second locking parts 31 recover their deformation and use the protruding teeth 42 to limit the exit direction, thereby completing the stable connection between the nose bridge frame 2, the headpiece 3 and the lens 1.

[0047] When the user needs to disassemble, he / she only needs to pull out the nose bridge 2 and the head piece 3 by hand in the direction of withdrawal. With the correct direction and a certain amount of external force, the first and second locking parts 31 will be driven to narrow again and undergo elastic deformation so that they can be pulled out.

[0048] Fourth, the frictional connection between the connector 4 and the through groove of the lens 1 facilitates installation, removal and replacement. The limiting flange 43 is set on the first end face of the lens 1 near the eye. When the nose bridge 2 and the post 3 on the other side are pulled out, the limiting flange 43 abuts against the lens 1 to prevent the connector 4 from being pulled out. With the nose bridge 2 and the post 3 covering the second end face of the lens 1, the connector 4 is hidden, making the frameless glasses look more integrated and beautiful when viewed by outsiders.

[0049] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
