Description

Technical Field

[0001] This utility model relates to a pair of eyeglasses, and more particularly to a pair of interchangeable-socket casual optical eyeglasses. Background Technology

[0002] Optical glasses are optical devices that correct vision by altering the path of light refraction through transparent lenses. Typical optical glasses consist of lenses, frames, and temples. The lenses are mounted in the frames, and the temples are attached to the ends of the frames using screws and hinges. Because the temples are screw-mounted, replacing them requires special tools, making the process somewhat inconvenient. Furthermore, the temples are typically made of plastic, which doesn't fit the wearer's head well and is unsuitable for casual or athletic wear.

[0003] In view of this, the inventor has studied and improved the structure of optical glasses and designed a new type of optical glasses with interchangeable temples that is suitable for leisure and sports, in order to solve the shortcomings of current optical glasses. Utility Model Content

[0004] The purpose of this invention is to provide a pair of interchangeable temple leisure optical glasses, which have easily replaceable temples, fit well to the wearer's head, and are suitable for leisure sports.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: These interchangeable temple casual optical glasses consist of lenses, a frame, and temples. The lenses are mounted in the frame. The frame has pivot joints at both ends, each with a longitudinal pivot groove and a transverse rotation groove. The pivot groove has a lower opening and an inner opening, the inner opening being flared. The rotation groove is connected to the middle section of the pivot groove. The temples are made entirely of nylon, with a pivot joint at the front end. This joint has a longitudinal pivot shaft and a transverse connecting rod. The pivot shaft passes through the lower opening and is inserted into the pivot groove. The connecting rod is fitted into the rotation groove through the inner opening, and its rotation within the groove causes the temples to open or close. Behind the pivot joint, the temples form a necked section covered by a rubber sleeve. A rubber pad is installed on the inner side of the rear section of the temples, and an adjustable metal core is located within the rear section.

[0006] The direction of the inner opening is parallel to the plane of the frame.

[0007] The lower opening has a step, and the lower end of the pivot shaft has a boss. The boss and the step cooperate to limit the axial movement of the pivot shaft when it is inserted into the pivot groove.

[0008] A retaining ring is formed between the connecting rod and the constricted section. The outer front end of the constricted section gradually thickens and connects to the retaining ring. A recess is formed on the outer front end of the constricted section. Correspondingly, the rubber sleeve gradually enlarges on the outer front end to form an flared opening.

[0009] The outer contour of the rubber sleeve smoothly transitions with the outer contour of the retaining ring and the outer contour of the rear section of the temple.

[0010] The longitudinal section of the constricted section is rectangular, with a short transverse side and a long longitudinal side.

[0011] The constricted section curves outward in an arc shape from front to back.

[0012] Anti-slip bumps are formed on the inner side of the rubber pad.

[0013] The rear section of the lens temple forms a groove on the inner side, and a locking hole is formed in the groove. A rubber pad is embedded in the groove, and a locking head is formed on the rubber pad. The locking head is tightly locked in the locking hole, so that the rubber pad is fixed in the groove.

[0014] The glasses are equipped with a secondary lens, which consists of a secondary lens and a secondary frame. The secondary lens is installed in the secondary frame, and a first magnet is installed at both ends of the secondary frame. A second magnet is installed at both ends of the frame. The secondary lens is assembled on the front of the glasses by means of the mutual attraction between the first magnet and the second magnet. The secondary lens forms a hook at the center bridge, and when the secondary lens is assembled on the front side of the glasses, the hook is hooked onto the center bridge of the glasses.

[0015] With the above structure, the temples of this invention are made entirely of nylon. The temples are hinged to the frame via a pivot joint at the front end that engages with pivot seats at both ends of the frame. There is no metal connection between the temples and the frame, enhancing safety. The entire temple is made of nylon, ensuring comfortable wear and a snug fit without pressure, making it suitable for sports and children. The temple's constricted neck section, combined with a rubber sleeve, provides a greater bending angle. The temple itself is highly flexible, suitable for various head shapes and widths. The temples unfold and fold using pivot seats and pivot joints, resulting in a simple structure, easy assembly, and good overall integrity. The temples can be positioned in either unfolded or folded state naturally without over-folding, facilitating repeated wear.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0019] The embodiments of this utility model will be fully described below with reference to the accompanying drawings. It should be noted that this utility model can be implemented in different forms, and the specific embodiments described herein are merely illustrative of the relevant structures and are not intended to limit the scope of the invention. These embodiments are provided to provide a thorough and complete disclosure of the utility model and to fully convey its scope to those skilled in the art. Furthermore, the embodiments and features described herein can be combined with each other without conflict. For ease of description, only the parts relevant to the inventive innovation are shown in the accompanying drawings.

[0020] See Figures 1 to 8As shown, the interchangeable temple casual optical glasses of this utility model consist of a lens 1, a frame 2, and temples 3. The lens 1 is installed in the frame 2. Pivot seats 21 are formed at both ends of the frame 2. Each pivot seat 21 has a longitudinal pivot groove 211 and a transverse rotation groove 212. The pivot groove 211 has a lower opening 213 and an inner opening 214. The inner opening 214 is flared. The rotation groove 212 communicates with the middle section of the pivot groove 211. The temples 3 are made entirely of nylon. A pivot joint 31 is formed at the front end of the temples 3. The pivot joint 31 has a longitudinal pivot shaft 311 and a transverse connecting rod 312. The pivot shaft 311 passes through the lower opening 213 from bottom to top and is inserted into the pivot groove 211. The connecting rod 312 is fitted into the rotation groove 212 through the inner opening 214. The rotation of the connecting rod 312 in the rotation groove 212 causes the temples 3 to unfold or retract. The temple 3 forms a constricted section 32 behind the pivot joint 31. A rubber sleeve 33 is wrapped around the constricted section 32. A rubber pad 34 is installed on the inner side of the rear section of the temple 3. The rubber pad 34 can increase the friction between the temple 3 and the head, making the temple 3 more stable to wear. An adjustable metal core 35 is provided in the rear section of the temple 3 to provide support and adjustability for the temple 3.

[0021] This invention utilizes a hinge joint 31 at the front end of the temple 3 to engage with the hinge seats 21 at both ends of the frame 2, creating a hinged connection between the temple 3 and the frame 2. Since there is no metal connection between the temple 3 and the frame 2, safety is enhanced. The entire temple 3 is made of nylon, ensuring comfortable wear and a more secure fit without pressure, making it suitable for sports and children. Furthermore, the temple 3's constriction section 32, in conjunction with the rubber sleeve 33, provides a greater bending angle. The temple 3 itself is highly elastic, suitable for wearers with various head shapes and widths. The temple 3's opening and closing are achieved through the hinge seats 21 and the hinge joint 31. The temple 3 has a simple structure, is easy to assemble, and has good overall integrity. In its natural state, the temple 3 can be positioned in either an open or closed state without over-closing, facilitating repeated wear.

[0022] Furthermore, in this invention, the opening direction of the inner opening 214 is approximately parallel to the plane of the frame 2. This requires the temple 3 to also be approximately parallel to the plane of the frame 2 during assembly, so that the pivot shaft 311 can be inserted into the pivot groove 211 from bottom to top through the lower opening 213. This limits both the angle of assembly and disassembly of the temple 3, as it is usually difficult for the temple 3 to be parallel to the plane of the frame 2. This design prevents the temple 3 from separating from the frame 2, thus ensuring the normal wearing and use of the glasses. Furthermore, the lower opening 213 of this invention has a step, and the lower end of the pivot shaft 311 has a boss 313. The boss 313 cooperates with the step of the lower opening 213, allowing the pivot shaft 311 to be axially limited when inserted into the pivot groove 211. This also allows the connecting rod 312 to quickly align with the rotating groove 212, and a slight rotation allows the temple 3 to be assembled onto the frame 2.

[0023] The optimized structure of this utility model is that a retaining ring 321 is formed between the connecting rod 312 and the constricted section 32. The retaining ring 321 allows the rubber sleeve 33 to fit better onto the constricted section 32, preventing misalignment. The outer front end of the constricted section 32 gradually thickens and connects to the retaining ring 321, and a recess 322 is formed on the outer front end of the constricted section 32, increasing the elasticity of the constricted section 32 and making it more comfortable to wear. Correspondingly, the rubber sleeve 33 gradually widens on the outer front end, forming an flared opening. Furthermore, the longitudinal section of the constricted section 32 of this utility model is rectangular, with a short horizontal side and a long vertical side. Further still, the constricted section 32 curves outward in an arc shape from front to back. This special shape design of the constricted section 32 gives it a certain vertical support force and a flexible force that allows it to bend left and right. Furthermore, the outer contour of the rubber sleeve 33, the outer contour of the retaining ring 321, and the outer contour of the rear section of the temple 3 of this utility model have a smooth transition, ensuring the integrity of the temple 3 and a more aesthetically pleasing appearance.

[0024] To facilitate the assembly of the rubber pad 34 onto the temple 3, the rear section of the temple 3 of this invention forms a groove 36 on its inner side, with a locking hole 361 formed in the groove 36. The rubber pad 34 is embedded in the groove 36, and a locking head 341 is formed on the rubber pad 34, which is tightly locked into the locking hole 361, thus fixing the rubber pad 34 in the groove 26. Furthermore, an optimized design of this invention is that anti-slip protrusions are formed on the inner side of the rubber pad 33 to increase friction and prevent the temple from sliding.

[0025] To enhance the functionality of the eyeglasses, the present invention further includes a secondary lens 4, which consists of a secondary lens 41 and a secondary frame 42. The secondary lens 41 is installed within the secondary frame 42, and first magnets 43 are mounted at both ends of the secondary frame 42. Second magnets 22 are mounted at both ends of the frame 42. The secondary lens 4 is assembled to the front of the eyeglasses by the mutual attraction between the first magnets 43 and the second magnets 22. Furthermore, to prevent the secondary lens 4 from slipping off the eyeglasses during movement due to gravity, the secondary lens 4 of the present invention features a hook 44 extending backward at the bridge. When the secondary lens 4 is assembled to the front of the eyeglasses, the hook 44 engages with the bridge, ensuring a secure attachment.

[0026] The embodiments described above are only for illustrating the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly, but they do not limit the patent scope of this utility model. All equivalent changes or modifications made in accordance with the spirit disclosed in this utility model should still be covered within the patent scope of this utility model.
