Description

Technical Field

[0001] The present invention relates to the field of glasses, and more particularly to glasses with replaceable lenses. Background Art

[0002] There are many types of glasses, such as myopia glasses that help people correct their vision, aging glasses, goggles and sunglasses that meet people's pursuit of travel and fashionable life, as well as diving goggles for sports and glasses with shock absorption function. In short, the use of glasses has become more and more extensive with people's needs. Among the above glasses, many glasses have fixed frames and lenses. This method is not only inconvenient to disassemble and assemble the lenses, but also requires users to bring a pair of glasses when going out, which is very space-consuming and inconvenient. Therefore, some designers should improve the fixing structure of glasses to solve the above problems.

[0003] In the prior art, there are many glasses structures with replaceable lenses, and there are countless related patent technologies. However, it is not difficult to find out from the structure that: when replacing the lenses of glasses with metal frames, it is generally necessary to use tools such as screwdrivers to complete the replacement operation, which makes the replacement operation troublesome; when replacing the lenses of glasses with plastic frames, although tools are generally not required, it is necessary to use a lot of force to squeeze the lenses to assemble them on the frame, and replacement is also inconvenient. For example, the most common glasses structure on the market is to set a screw fixing fastening structure on the frame, and the lenses can be quickly replaced by unscrewing the screws, and to set a slide groove to remove and replace the lenses through sliding insertion. For example, the Chinese patent application No. 200910112164.2 is named: A pair of glasses with conveniently replaceable lenses. The disclosed pair of glasses can also realize convenient detachable and fixed lenses through a convex card and a rocker rod, but it has a great impact on the appearance, and its improved overall structure is fragile and easy to damage, making it difficult to produce.

[0004] Secondly, the Chinese patent number is: ZL2019203600956, and the invention name is: A pair of glasses with replaceable lenses, which discloses a pair of glasses with removable lenses that are elastically plugged and fixed with springs and other components. However, the applicant found the following problems in actual use: 1. Material restrictions, the product uses a lot of materials. This structure is only suitable for plastic frames, and metal materials are difficult to use and manufacture; 2. The clamping structure is complex and inconvenient to produce, which is not in line with the interests; 3. The clamping structure occupies a large volume and is not beautiful in appearance. This patent is a patent previously designed and developed by the applicant. The previous patents mainly provide the design of movable assembly and disassembly of lenses and frames to facilitate the replacement of lenses; however, the applicant is not satisfied with this for research and innovation, so in line with the concept of continuous improvement, and with the assistance of many years of manufacturing and design experience and knowledge in related fields, and through various ingenuity, the technical solution of the present invention has been continuously developed. Summary of the invention

[0005] The object of the present invention is to provide a pair of glasses whose lenses can be easily replaced and whose structural design is simple and ingenious without affecting the appearance characteristics of the product.

[0006] The following technical solution is provided: a pair of glasses with replaceable lenses, comprising a frame, a nose pad, a lens assembly detachably matched with the frame, temples connected to both sides of the frame, and a connecting part fixed on the outside of the frame for hinged connection with the temples, characterized in that: the lens assembly comprises a lens, an inner frame fixedly arranged along the outer contour of the lens, the frame is arranged in a closed loop along the edge of the lens assembly and its cross-section is "L"-shaped, the frame is fixedly provided with an auxiliary piece on the rear side surface close to the nose pad so that the cross-section of the frame at this location is "U"-shaped, and also includes a plug-in assembly welded and fixedly arranged on the rear side surface of the connecting part of the outer side surface of the frame, the frame is provided with a through hole facing the plug-in assembly, the inner frame is provided with a plug-in groove facing the through hole, the plug-in assembly protrudes from the frame through the through hole and is plug-fitted with the plug-in groove, and is used for elastic plug-in fixing of the lens assembly.

[0007] As a further configuration of the above scheme, a hole groove is provided on the plug-in component, the diameter of the through hole is smaller than the diameter of the hole groove, and a plug-in component elastically abutting against the bottom of the hole groove is also provided in the hole groove, the front end portion of the plug-in component is hemispherical and protrudes from the through hole, the plug-in groove provided on the side wall of the inner frame facing the front end of the plug-in component is conical, and the lens assembly is fixed by elastic plug-in cooperation with the "U"-shaped partial frame and the plug-in groove and the plug-in component.

[0008] As a further configuration of the above solution, a top spring for elastic insertion of the connector is provided between the rear end of the connector located at the hole slot and the bottom of the hole slot.

[0009] As a further configuration of the above solution, the front profile of the "L"-shaped frame covers the inner frame profile.

[0010] As a further configuration of the above solution, the cross section of the inner frame is "U"-shaped, and the lens is fixed to the inner frame.

[0011] As a further configuration of the above scheme, the end face of the plug-in component facing the temple side is provided with a threaded hole, and a screw for adjusting the plug-in strength is threadedly connected, a pad is clamped between the screw and the top spring, and a corresponding threaded hole is provided on the temple for a tool to pass through an opening for rotating the screw, and the frame, temple, and inner frame plug-in component are made of metal material.

[0012] The present invention provides a pair of glasses with interchangeable lenses, which have the following technical effects and features compared with the prior art:

[0013] 1. The outer edge of the detachable lens of the present invention is wrapped with an inner frame. The inner frame with a U-shaped cross section wraps the edge of the lens as a whole, which greatly improves the overall strength of the replaceable lens. The strength of the metal inner frame is used to support the lens, so that the lens can be made thinner to meet the lightweight requirements of the glasses, and can avoid damage during the disassembly process;

[0014] Second, one of the features of the glasses of the present invention is that the lenses can be replaced easily, simply and quickly.

The frame structure design of the glasses of the present invention forms a U-shaped part by the L-shaped frame and the auxiliary piece on one side, and cooperates with the design of the plug-in assembly on the other side for elastic plugging, so that the lenses can be easily and quickly disassembled and assembled without tools or effort. At the same time, when the lenses are pressed correctly and vigorously during non-active disassembly and assembly, the lenses and the frame are not easily separated accidentally, which affects the use;

[0016] Fourth, the front side of the frame of the present invention is shielded against the installed inner frame, so that the lens assembly is not easy to identify the structure of the double frame of the present invention from the front after installation, making the glasses of the present invention more integrated. The fixed design of the plug-in assembly hides the external features and hides the plugged parts inside the invisible area. When disassembling the lens assembly, the structure composed of the connecting part and the plug-in assembly can be used as a support. Secondly, a side opening and a top screw and a pad clamped by a top screw top spring are also provided, which are used to control the activity space of the top spring and the minimum elastic force applied to the plug-in component. The present invention uses the rotation of the top screw to adjust its relative position, so as to achieve the design and technical effect of adjusting its elastic disassembly and assembly to be more in line with the easy and simple replacement of lenses;

[0017] 5. The overall appearance of the present invention makes full use of the existing elements of glasses. Under the premise of having an elastic plug-in structure to achieve the technical effect of easy removal and replacement of lenses and not easy to fall off, the ingenious design does not affect its aesthetics at all, so that there is basically no difference in appearance between this solution and existing glasses. The structure is simpler and more ingenious, while mainly maintaining the consistent characteristics of the beautiful appearance of metal frame glasses. The glasses of the present invention have broad market competitiveness in terms of appearance combined with its technical effect and function improvements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-3 The present invention discloses a pair of glasses with replaceable lenses, comprising a frame 1, a nose pad 3, a lens assembly 2 detachably matched with the frame 1, temples 4 connected to both sides of the frame 1, and a connecting portion 9 fixed on the outside of the frame 1 for hinged connection with the temples 4, characterized in that: the lens assembly 2 comprises a lens 21, an inner frame 22 fixedly arranged along the outer contour of the lens 21, the frame 1 is arranged in a closed loop along the edge of the lens assembly 2 and its cross section is "L"-shaped, the frame 1 is fixedly provided with an auxiliary piece 31 on the rear side surface close to the nose pad 3, so that the cross section of the frame 1 at this location is "U"-shaped, and also includes a plug-in assembly 5 welded and fixedly arranged on the rear side surface of the connecting portion 9 on the outer side surface of the frame 1, the frame 1 is provided with a through hole 512 facing the plug-in assembly 5, the inner frame 22 is provided with a plug-in groove 515 facing the through hole 512, the plug-in assembly 5 protrudes from the frame 1 through the through hole 512 and is plug-matched with the plug-in groove 515, and is used for elastic plug-in fixing of the lens assembly 2.

[0024] As a further arrangement of the above scheme, a hole groove 511 is arranged on the plug-in assembly 5, the diameter of the through hole 512 is smaller than the diameter of the hole groove 511, and a plug-in component 514 elastically abutting against the bottom of the hole groove 511 is also arranged in the hole groove 511, and the front end portion of the plug-in component 514 is hemispherical and protrudes from the through hole 512, and the plug-in groove 515 arranged on the side wall of the inner frame 22 facing the front end portion of the plug-in component 514 is conical, and the lens assembly 2 is fixed by elastic plug-in cooperation with the "U"-shaped partial frame 1 and the plug-in groove 515 and the plug-in component 514.

[0025] As a further configuration of the above solution, a top spring 516 for elastically plugging the plug-in component 514 is provided between the rear end of the plug-in component 514 located at the hole slot 511 and the bottom of the hole slot 511 .

[0026] By setting up the above scheme, the elastic force of the top spring 516 is utilized to drive the connector 514 to maintain the state of protruding inside the frame 1 when there is no external pressure, and elastically retract into the hole groove 511 when subjected to external pressure, and quickly reset after the pressure is lost. When the lens assembly 2 is installed and reset, the connector 514 and the insertion groove 515 can be plugged in and matched.

[0027] As a further configuration of the above solution, the front profile of the “L”-shaped frame 1 covers the profile of the inner frame 22 .

[0028] Through the above arrangement, the frame 1 covers the contour of the inner frame 22, so that after the lens assembly 2 is installed and fixed, it is difficult for the user to distinguish the double frame from the front when wearing the glasses, thereby avoiding damaging the aesthetics of the glasses.

[0029] As a further configuration of the above solution, the cross section of the inner frame 22 is “U”-shaped, and the lens 21 is fixed to the inner frame 22 .

[0030] By means of the above arrangement, when the lens assembly 2 is carried independently, the lens 21 is firmly fixed to the inner frame 22, so that the lens 21 is protected by the inner frame 22 when carried independently to avoid scratches, abrasion and breakage.

[0031] As a further arrangement of the above scheme, a threaded hole is provided on the end face of the plug-in component 5 facing the temple 4, and a screw for adjusting the plug-in strength is threadedly connected thereto. A pad is clamped between the screw and the top spring 516. A corresponding threaded hole is provided on the temple 4 for a tool to pass through an opening for rotating the screw. The screw is driven by the tool to rotate deep into the threaded hole, and the pad is pushed toward the plug-in block 514, compressing the top spring 516, so that the elastic force of the top spring 516 changes, so as to enhance the pressure exerted on the plug-in block 514, and vice versa, it can be reduced, thereby adjusting the plug-in strength. The frame 1, temple 4, inner frame 22 plug-in component 5 are made of metal material.

[0032] Through the arrangement of the above scheme, when the top spring 516 of the elastic plug-in structure is worn and aged after long-term use, or the lens assembly 2 is easy to fall off and difficult to disassemble, the screw can be adjusted to maintain a plug-in strength that is easy to disassemble and firmly installed. The screw can be screwed into the interior of the plug-in assembly through a top screw body, and the diameter of the opening on the outside is smaller, which has less impact on the appearance.

[0033] Embodiment 1: When manufacturing the glasses of the present invention, various parts are directly manufactured by metal processing technology, and then the auxiliary piece 31 is welded to the part of the L-shaped frame 1 near the nose pad 3, so that the L-shaped frame 1 is U-shaped at this point, and the connecting part 9 for hingedly connecting the temples 4 on the glasses is fixed to the outer edge of the frame 1 farthest from the U-shaped part, and then a plug-in assembly 5 with a hole groove 511 and smaller than the size of the connecting part 9 is arranged, and a top spring 516 is placed at the bottom of the hole groove 511, and then a plug-in component 514 with a larger rear end and a smaller front end is placed, and then a through hole 512 with a larger rear end and a smaller front end is drilled in advance on the outer wall of the frame 1 opposite to the hole groove 511, and the diameter of the through hole 512 is smaller than the diameter of the hole groove 511, and finally the plug-in assembly 5 is welded to the connecting part 9 and the outer wall of the frame 1, and the front end of the plug-in component 514 protrudes through the through hole 512 and is arranged in the frame 1;

[0034] The lens assembly 2 is provided with a U-shaped inner frame 22 on the outer edge of the lens 21 to fix the lens 21; when in use, first align the lens assembly 2 with the U-shaped part of the frame 1 to engage it, and then press the lens assembly 2 on one side from the back to the front to achieve the overall fixation of the glasses. When replacing, the reverse operation is performed through the cooperation of the hemispherical connector 514 and the connector groove 515 at the front end to achieve disassembly and assembly under a certain pressure.

[0035] The glasses of the present invention, whose lens assembly 2 can be independently produced and sold, can be configured with multiple pairs of lens assemblies 2 for different purposes according to user needs, such as sunglasses, 3D glasses, photochromic glasses, etc. The advantages of the lens assembly 2 of the present invention having an inner frame 22 disposed on the outer edge of the lens 21 are, first, avoiding the outer edge of the lens 21 from hurting the hand when replacing; second, when the user carries the lens assembly 2, the inner frame 22 enhances the strength of the thin lens 21 and the pressure transmission during disassembly and assembly, thereby avoiding wear and cracking of the outer edge of the lens 21.

[0036] The glasses of the present invention have a frame 1 that is arranged in an L-shaped closed loop along the cross-section of the lens assembly 2, an auxiliary piece 31 is arranged on the part on the side of the nose pad 3 to form a frame 1 structure with a U-shaped cross-section, a plug-in assembly 5 is arranged on the outer side of the frame 1 farthest from the auxiliary piece 31, a hole groove 511 is arranged on the plug-in assembly 5 facing the outer wall of the frame 1, a through hole 512 is arranged on the outer wall of the frame 1, the hole groove 511 is provided with a connector 514 that is arranged on the inner side of the frame 1 with a rear end clamped on the outer side of the frame 1 and a front end protruding through the through hole 512; the lens assembly 2 is provided with a conical plug-in groove 515 on the outer wall of the inner frame 22 facing the plug-in groove 514, a top spring 516 is arranged between the rear end of the plug-in assembly 514 and the bottom of the hole groove 511, one side of the lens assembly 2 is clamped into the U-shaped part of the frame 1, and the other side is detachably fixed by elastically plugging the connector 514 and the plug-in groove 515. The advantages are: first, the U-shaped frame is firmly fixed by the elastic plug-in on the other side of the snap-fit, and if it is not tight enough, the strength can be simply adjusted by screws; second, the frame 1 has an L-shaped cross-section, and the frame 1 partially covers the inner frame 22 of the lens assembly 2 from the front perspective, so that it is not easy to distinguish the product from the front as having a double frame; third, the plug-in assembly 5 is welded and fixed to the connecting portion 9, and there is no difference in appearance compared to the connecting portion 9 of the existing product, so that the overall appearance of this product is no different from that of ordinary glasses while meeting the technical purpose.

[0037] like Figure 3As shown, using a top screw as the elastic adjustment screw of the top spring 516 can better protect the appearance. The top screw is rotated by a tool inserted through the opening to make it penetrate into the screw hole, and the cushion block is pushed toward the top spring 516, thereby compressing the activity space of the top spring 516 and changing its minimum elastic force, which in turn causes the strength of the pressure of its elastic recovery against the connector 514 to change, so as to change the elastic plug-in strength of the connector assembly 5 and adjust whether the lens assembly 2 is convenient and easy to disassemble and assemble.

[0038] The present invention provides a pair of glasses with interchangeable lenses, which have the following technical effects and features compared with the prior art:

[0039] 1. The outer edge of the detachable lens of the present invention is wrapped with an inner frame. The inner frame with a U-shaped cross section wraps the edge of the lens as a whole, which greatly improves the overall strength of the replaceable lens. The strength of the metal inner frame is used to support the lens, so that the lens can be made thinner to meet the lightweight requirements of the glasses, and can avoid damage during the disassembly process;

[0040] Second, one of the features of the glasses of the present invention is that the lenses can be replaced easily, simply and quickly. Therefore, when using this product, customers can carry a variety of replacement spare lenses. The design of the inner frame makes it difficult for the lenses of this product to scratch the hands when disassembling and assembling, and it is not easy to be damaged or broken when carrying;

[0041] 3. The frame structure design of the glasses of the present invention forms a U-shaped part by the L-shaped frame and the auxiliary piece on one side, and cooperates with the design of the plug-in assembly on the other side for elastic plugging, so that the lenses can be easily and quickly disassembled and assembled without tools or effort. At the same time, when the lenses are pressed correctly and vigorously during non-active disassembly and assembly, the lenses and the frame are not easily separated accidentally, which affects the use;

[0042] Fourth, the front side of the frame of the present invention is shielded against the installed inner frame, so that the lens assembly is not easy to identify the structure of the double frame of the present invention from the front after installation, making the glasses of the present invention more integrated. The fixed design of the plug-in assembly hides the external features and hides the plugged parts inside the invisible area. When disassembling the lens assembly, the structure composed of the connecting part and the plug-in assembly can be used as a support. Secondly, a structure for controlling the plug-in strength adjustment is also provided on the side, so that its elastic disassembly and assembly is more in line with the design and technical effect of easy and simple replacement of lenses.

[0043] 5. The overall appearance of the present invention makes full use of the existing elements of glasses. Under the premise of having an elastic plug-in structure to achieve the technical effect of easy removal and replacement of lenses and not easy to fall off, the ingenious design does not affect its aesthetics at all, so that there is basically no difference in appearance between this solution and existing glasses. The structure is simpler and more ingenious, while mainly maintaining the consistent characteristics of the beautiful appearance of metal frame glasses. The glasses of the present invention have broad market competitiveness in terms of appearance combined with its technical effect and function improvements.

[0044] The above description is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
