DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0021] The following is a specific embodiment to illustrate the implementation of the present disclosure. Persons skilled in the art can easily understand the other advantages and effects of the present disclosure from the disclosure in the specification.

[0022] Referring to FIG. 1 to FIG. 6, according to a preferred embodiment of the present disclosure, a lens-changeable glasses is provided. The side facing a wearer's face is defined as the inner surface, and the side not facing the wearer's face is defined as the outer surface, and the glasses mainly includes a lens 1, a pivot fastener 2, and a wearing piece 3.

[0023] A nose bridge cover 11 is provided at the lower edge of the center of lens 1, and a mounting base 12 is provided on both sides thereof. The front section of the mounting base 12 is combined with the lens 1. The present disclosure does not limit the manner in which the mounting base 12 is combined with the lens 1, and it is secured to the lens 1 on both sides of the lens 1 by one of gluing, welding, locking, embedding, or secondary injection. A stopper 121 extends from the top and bottom of the front section of the mounting base 12, and a longitudinally penetrating mounting hole 122 is provided at the rear section of the mounting base 12. In the embodiment of the present disclosure, the mounting hole 122 is in the shape of an elongated hole, but is not limited thereto. In addition, in the embodiment of the present disclosure, the lens 1 is a one-piece type, but is not limited thereto. It can also be a two-piece type, and the lens can be one of a prescription lens, a sunshade lens, a goggle lens, or a photochromic lens.

[0024] The inner surface of each pivot fastener 2 is provided with a clamping slot 21 and a pivot slot 22, and a limiting portion 211 is extended from the top to bottom of the front section of each clamping slot 21. The pivot slot 22 has a lower opening 221. The shapes of the clamping slot 21 and the pivot slot 22 match the shape of the mounting base 12. A mounting shaft 222 extends downward from the top of the pivot slot 22, and each pivot fastener 2 can be detachably inserted in the mounting hole 122 by the mounting shaft 222. Each pivot fastener 2 is pivoted relative to the mounting base 12 between an unfolded position L1 and a folded position L2 with the mounting shaft 222 as the axis.

[0025] The wearing piece 3 may be a belt or two temples 31. The present disclosure takes two temples 31 as an example for illustration. As shown in FIG. 4, each of the temples 31 is respectively pivotally connected to the rear section of each of the pivot fasteners 2 and can be pivoted relative to the pivot fasteners 2. The present disclosure does not limit the sequence of assembling each of the temples 31. As shown in FIG. 3, each of the temples 31 may be first1 pivotally connected to each of the pivot fasteners 2 first, and then each of the pivot fasteners 2 is assembled on the mounting base 12. Alternatively, each of the pivot fasteners 2 is assembled on the mounting base 12, and then each of the temples 31 is pivotally connected to the rear section of each of the pivot fasteners 2.

[0026] Referring to FIG. 3 to FIG. 6, when each of the pivot fasteners 2 is actually assembled, each of the pivot fasteners 2 is first placed in the folded position L2, the mounting shaft 222 is inserted into the mounting hole 122 from the top to the bottom, and subsequently each of the pivot fasteners 2 is pivoted from the folded position L2 to the unfolded position L1. As shown in FIG. 5, the limit portion 211 pivots to the stopper 121 to form an interference. The partially enlarged view is to indicate the part of the pivot interference by the slash area. The user only needs to apply a slight force during the pivoting to force the limit part 211 into the inner surface of the stopper 121 to form a fixation. In addition, when each of the pivot fasteners 2 is in the unfolded position L1, and the mounting base 12 is partially accommodated in the clamping slot 21 and the pivot slot 22, thereby limiting the longitudinal displacement of each of the pivot fasteners 2 relative to the mounting base 12.

[0027] When the user replaces the lens 1, the user only needs to apply force to press the outer surface of the rear section of each pivot fastener 2, such that the pivot fastener 2 pivots from the unfolded position L1 to the folded position L2 with the mounting shaft 222 as the axis. The limit part 211 is pivoted to force out the stopper 121, and each of the pivot fasteners 2 can be operated to disengage the mounting shaft 222 from the mounting hole 122, such that each of the pivot fasteners 2 together with the temples 31 are detached from the mounting base 122 for replacement of the lens 1. Alternatively, as shown in FIG. 3, the pivot fasteners 2 together with the temples 31 are replaced.

[0028] In order to make the assembly structure of each pivot fastener 2 more reliable, a protrusion 223 is provided on the outer edge of the mounting shaft 222 of each pivot fastener 2. The inner surface of the mounting base 12 is provided with an embedding groove 123 connected to the mounting hole 122. When each of the pivot fasteners 2 is pivoted to the unfolded position L1, the protrusion 223 is embedded in the embedding groove 123 along with the pivoting, thereby further limiting the longitudinal displacement of each of the pivot fasteners 2 relative to the mounting base 12. When each of the pivot fasteners 2 is pivoted to the folded position L2, as shown in FIG. 4, the protrusion 223 will be disengaged from the embedding groove 123 as the pivot fasteners 2 are pivoted, so as to facilitate detachment of the pivot fasteners 2 for replacement of the lens 1.

[0029] Referring to FIG. 7 to FIG. 12, which show embodiments of the present disclosure in accordance with the structural variations described above, and the same structures will not be repeated. In the embodiment of the present disclosure, the rear end of each of the pivot fasteners 2 is provided with a strap hole 23, and the wearing piece 3 is a belt body. The two ends of the wearing piece 3 are respectively coupled to the strap holes 23. The belt body may be an elastic band or a hook and loop fastener, but is not limited thereto. Any belt body that can be combined in the rear end of each of the pivot fasteners 2 and can be worn and fixed to the user's head is within the scope of the present disclosure.

[0030] The present disclosure further includes a front frame 4. The front frame 4 is provided with a groove 41 on both sides thereof, and a socket 411 is provided at the bottom of each groove 41. The insertion hole 411 is coaxial with the mounting shaft 222. As shown in FIG. 8 and FIG. 12, the front frame 4 is further provided with a lens groove 42 and a positioning protrusion 43. The front frame 4 is provided with a plurality of ventilation holes 45 around the periphery of the lens groove 42. In the embodiment of the present disclosure, the lens groove 42 is arranged on the outer surface of the front frame 4, and the positioning protrusion 43 is located at the inner frame edge of the front frame 4 corresponding to the bridge of the human nose of the human body. The nose bridge cover 11 of the lens 1 is recessed with a positioning groove 111, the lens 1 is detachably arranged in the lens groove 42, and the positioning protrusion 43 is embedded in the positioning groove 111 to form a positioning.

[0031] As shown in FIG. 7 to FIG. 11, after each of the pivot fasteners 2 is assembled on each of the mounting bases 12, the end of each of the mounting shafts 222 is inserted into each of the insertion holes 411. In addition, when each of the pivot fasteners 2 is in the unfolded position L1, a portion thereof is accommodated in each of the grooves 41, thereby limiting the longitudinal displacement of each of the pivot fasteners 2 relative to each of the mount bases 12.

[0032] Furthermore, the embodiment of the present disclosure further includes a rear frame 5 detachably arranged on the inner surface of the front frame 4, and the frame edge of the rear frame 5 is provided with a plurality of hook portions 51. The frame edge of the inner surface of the front frame 4 is provided with a plurality of outwardly facing trenches 44, as shown in FIG. 13, and the rear frame 5 is secured by hooking each of the hook portions 51 correspondingly in the trenches. The present disclosure does not limit the material of the rear frame 5, which may be made of plastic or flexible and cushioning material, such as rubber, silicone, foam, and the like.

[0033] Herein, the embodiment of the present disclosure forms the form of sports glasses by configuring the front frame 4 and the rear frame 5 and replacing the wearing piece 3. In addition to being able to quickly replace the lens 1 without the aid of tools, the present disclosure can also be used with different types of wearing piece 3 to enhance product diversity and market competitiveness.
