Abstract
Description
Technical Field
[0001] This invention relates to eyeglasses, and more particularly to a structure in which the lens can be separated or attached to the temple without the need for tools, and the lens can be replaced. Background Technology
[0002] Currently, eyeglasses typically have a single function, including correcting myopia, hyperopia, astigmatism, presbyopia, or strabismus. Other functional eyeglasses include goggles, sunglasses, and sports glasses, providing various forms of eye protection. Consumers can choose to wear them according to different occasions. As a result, it is common for consumers to own multiple pairs of different functional eyeglasses for easy switching. However, this situation also creates an economic burden for consumers and raises the issue of eyeglass storage.
[0003] Therefore, replaceable lens eyeglasses have emerged. Their main structure features a corresponding interlocking mechanism between the periphery of the lens and the periphery of the frame, allowing consumers to remove and replace the lens themselves and reattach it to the frame. This structure is commonly found in semi-rimless or full-rimmed eyeglasses. However, most existing rimless eyeglasses have the temples directly pivoted to the sides of the lens, and few have a lens replacement mechanism designed specifically for rimless eyeglasses. As a result, traditional eyeglass structures are gradually failing to meet users' desire for novelty, change, and even diversification. Summary of the Invention
[0004] In view of the shortcomings and deficiencies of the prior art, the present invention provides an eyeglass structure that can quickly separate the lens from the wearer without the need for tools.
[0005] To achieve the above objectives, the technical means adopted in this invention is a pair of glasses with replaceable lenses, which defines the side facing the wearer's face as the inner surface and the side facing outwards as the outer surface, mainly including: A lens has a mounting base on each side. The front of the mounting base has a stop and the rear has a longitudinal through mounting hole.
[0006] Two pivot fasteners, each having a limiting portion at its front end and a downwardly extending mounting shaft spaced apart from the limiting portion, allow each pivot fastener to be detachably inserted into the mounting hole via the mounting shaft. Each pivot fastener pivots relative to the mounting base between an unfolded position and a retracted position, with the mounting shaft as its axis. A single fitting is attached to the back of each pivot fastener.
[0007] When each pivot member pivots from the closed position to the extended position, the limiting part is forced into the inner surface of the stop part to form a fixed position; when each pivot member pivots from the extended position to the closed position, the limiting part is forced out of the stop part, and each pivot member can operably disengage the mounting shaft from the mounting hole, so that each pivot member can be removed from the mounting base for lens replacement, improving the convenience of lens replacement.
[0008] Furthermore, each pivot member has a protrusion on its mounting shaft, and each mounting base has a groove on its inner surface that connects to the mounting hole. When each pivot member pivots to the unfolded position, the protrusion is inserted into the groove as it pivots. When each pivot member pivots to the retracted position, the protrusion is disengaged from the groove as it pivots.
[0009] Furthermore, each pivot member has a connected slot and a pivot groove on its inner surface. The pivot groove has a bottom opening, and the mounting shaft extends downward from the top of the pivot groove. When the pivot member is in the unfolded position, the mounting base is partially accommodated in the slot and the pivot groove.
[0010] Furthermore, it also includes a front frame with a slot on each side. Each slot has an insertion hole at the bottom coaxial with the mounting shaft. The front frame also has a lens slot and a positioning protrusion. The lens has a positioning groove and can be detachably placed in the lens slot. The positioning protrusion is embedded in the positioning groove to form a positioning. When each pivot fastener is assembled on each mounting base, the end of each mounting shaft is inserted into the insertion hole. When each pivot fastener is in the unfolded position, it is accommodated in each slot.
[0011] Furthermore, the positioning protrusion is located at the corresponding human nose bridge of the front frame.
[0012] Furthermore, the inner surface edge of the front frame is provided with multiple outward-facing grooves, and a rear frame is detachably disposed on the inner surface of the front frame, and the rear frame edge is provided with multiple hooks, each hook being hooked into each groove.
[0013] Furthermore, the front frame has multiple vent holes around the periphery of the lens slot.
[0014] Furthermore, each mounting bracket is fixed to both sides of the lens by means of adhesive, welding, locking, or embedding.
[0015] Furthermore, the fitting is either a band or one of two temples.
[0016] The beneficial effects of the present invention are as follows: by setting the front frame 4 and the rear frame 5 and replacing the wearing part 3, the present invention is made into the form of sports glasses. In addition to being able to quickly replace the lens 1 without the aid of tools, the present invention can also be used with different types of wearing parts 3 to enhance product diversification and market competitiveness.

[0031] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.
[0032] Please see Figures 1 to 6 As shown, a preferred embodiment of the present invention provides a replaceable lens eyeglass, defining the side facing the wearer's face as the inner surface and the side facing outwards as the outer surface. The eyeglass mainly includes: a lens 1, two hinges 2, and a wearing member 3. A nose bridge cover 11 is provided at the lower central edge of the lens 1, and a mounting seat 12 is provided on each side. The front section of each mounting seat 12 is attached to the lens 1. The present invention does not limit the manner in which the mounting seats 12 are attached to the lens 1; they can be fixed to both sides of the lens 1 by adhesive, welding, locking, embedding, or encapsulation injection. A stop portion 121 extends from the top and bottom of the front section of each mounting seat 12, and a longitudinally penetrating mounting hole 122 is provided at the rear section of each mounting seat 12. In this embodiment, the mounting hole 122 is elongated, but not limited thereto. Furthermore, in this embodiment, the lens 1 is a single piece, but it is not limited to this and can also be a two-piece lens. The lens can be one of the following: a prescription lens, a sunshade lens, a protective lens, or a photochromic lens.
[0033] Each pivot fastener 2 has a connected slot 21 and a pivot groove 22 on its inner surface. Each slot 21 has a limiting part 211 extending from its top and bottom. The pivot groove 22 has a bottom opening 221. The shapes of the slot 21 and the pivot groove 22 match the mounting base 12. The top of the pivot groove 22 extends downward to a mounting shaft 222. Each pivot fastener 2 can be detachably inserted into the mounting hole 122 with the mounting shaft 222 as the axis. Each pivot fastener 2 pivots relative to the mounting base 12 between an unfolded position L1 and a retracted position L2 with the mounting shaft 222 as the axis.
[0034] The wearing accessory 3 can be a strap or two temples 31. This embodiment uses two temples 31 as an example for illustration. Figure 4 As shown, each temple 31 is pivotally connected to the rear section of each pivot fastener 2 and can pivot relative to the pivot fastener 2. The present invention does not limit the assembly order of the temples 31; each temple 31 can be arranged as follows: Figure 3 As shown, after each pivot fastener 2 is pivotally connected to the other pivot fastener 2, the other pivot fastener 2 is then mounted on the other mounting base 12. Alternatively, after each pivot fastener 2 is mounted on the other mounting base 12, the other temple 31 is pivotally connected to the rear section of each pivot fastener 2.
[0035] Please refer to the following for further information. Figures 3 to 6As shown, during the actual assembly of each pivot fastener 2, first, each pivot fastener 2 is placed in the closed position L2, then the mounting shaft 222 is inserted from top to bottom into the mounting hole 122, and then each pivot fastener 2 is pivoted from the closed position L2 to the unfolded position L1, as shown. Figure 5 As shown, when the limiting part 211 pivots to the stop part 121, interference will occur. The part of the pivot interference is indicated by the diagonal lines in the enlarged view. The user only needs to apply a little force when pivoting to force the limiting part 211 into the inner surface of the stop part 121 to form a fixation. When each pivot fastener 2 is in the unfolded position L1, the mounting base 12 is partially accommodated in the slot 21 and the pivot groove 22, thereby restricting the longitudinal displacement of each pivot fastener 2 relative to each mounting base 12.
[0036] When the user replaces lens 1, they only need to apply force to press the outer surface of the rear section of each pivot 2, causing the pivot 2 to pivot from the unfolded position L1 to the retracted position L2 around the mounting shaft 222. The limiting part 211 is forced out of the stop part 121 as it pivots, and each pivot 2 can operably disengage the mounting shaft 222 from the mounting hole 122, so that each pivot 2, together with each temple 31, is detached from the mounting base 12 for lens 1 replacement, or as... Figure 3 As shown, the pivot fastener 2 and the temple 31 are replaced.
[0037] To make the assembly structure of each pivot fastener 2 more robust, a protrusion 223 is provided on the outer edge of the mounting shaft 222 of each pivot fastener 2, and a groove 123 is provided on the inner surface of each mounting base 12 connecting to the mounting hole 122. When each pivot fastener 2 pivots to the unfolded position L1, the protrusion 223 is inserted into the groove 123 as it pivots, thereby further restricting the longitudinal displacement of each pivot fastener 2 relative to each mounting base 12. When each pivot fastener 2 pivots to the retracted position L2, as... Figure 4 As shown, the protrusion 223 will pivot and disengage from the groove 123, so as to facilitate the removal of the pivot fastener 2 for the replacement of the lens 1.
[0038] Please refer to the following: Figures 7 to 12 This is an embodiment of the present invention based on the above-described structural changes, so the same structure will not be described again. In this embodiment, each pivot fastener 2 has a strap hole 23 at its rear end. The wearing member 3 is a strap body, and both ends of the wearing member 3 are respectively connected to the strap hole 23. The strap body can be an elastic band or a hook and loop fastener, but is not limited to these. Anything that can be connected to the rear end of each pivot fastener 2 and can be worn and fixed to the user's head is within the scope of the present invention.
[0039] It also includes a front frame 4, with a slot 41 on each side of the front frame 4, and an insertion hole 411 at the bottom of each slot 41. The insertion hole 411 is coaxial with the mounting shaft 222, and as shown... Figure 8 and Figure 12As shown, the front frame 4 also has a lens groove 42 and a positioning protrusion 43. The front frame 4 has multiple ventilation holes (not shown in the figure) near the periphery of the lens groove 42. In this embodiment, the lens groove 42 is located on the outer surface of the front frame 4, and the positioning protrusion 43 is located at the inner edge of the front frame 4 corresponding to the bridge of the nose. The nose bridge sleeve 11 of the lens 1 has a recessed positioning groove 111. The lens 1 is detachably disposed within the lens groove 42, and the positioning protrusion 43 is embedded in the positioning groove 111 to form a positioning.
[0040] See also Figures 7 to 11 As shown, when each pivot fastener 2 is assembled in each mounting base 12, the end of each mounting shaft 222 is inserted into each insertion hole 411, and when each pivot fastener 2 is in the unfolded position L1, its part is accommodated in each slot 41, thereby restricting the longitudinal displacement of each pivot fastener 2 relative to each mounting base 12.
[0041] Meanwhile, this embodiment also includes a rear frame 5 detachably disposed on the inner surface of the front frame 4, and the rear frame 5 has a plurality of hook portions 51 on its frame edge, and the inner surface of the front frame 4 has a plurality of outwardly opening grooves 44, such as... Figure 13 As shown, the rear frame 5 is fixed by hooking each hook portion 51 into each groove 44. The present invention does not limit the material of the rear frame 5, which can be made of plastic or soft and flexible material, cushioning material, such as rubber, silicone, foam, etc.
[0042] Therefore, this embodiment forms a sports glasses by setting the front frame 4 and the rear frame 5 and replacing the wearing part 3. In addition to being able to quickly replace the lens 1 without the aid of tools, the present invention can also be used with different types of wearing parts 3 to enhance product diversification and market competitiveness.
