Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a stretchable temple and eyeglasses. Background Technology

[0002] With the development of technology in the eyewear manufacturing industry, eyeglasses, as an important tool for correcting vision and protecting the eyes, have had their structural designs continuously optimized to meet people's needs for wearing comfort and practicality. The temples, as the key components that come into contact with the wearer's head, directly determine the stability and comfort of wearing eyeglasses, and are one of the core elements affecting user experience.

[0003] In traditional technology, eyeglass temples are generally designed with a fixed length, meaning the overall size of the temples is determined during manufacturing. This makes it impossible to adapt them to different wearers' head shapes, facial contours, and other differences. However, with current fixed-length temples, it is difficult to meet the needs of different people simultaneously due to variations in head size. This can easily lead to problems such as temples that are too tight, causing a strong feeling of pressure on the head, or temples that are too loose, causing the glasses to slip off easily. There is a technical problem where the length of the temples limits the comfort of wearing eyeglasses. Utility Model Content

[0024] like Figures 1 to 2 As shown, it is the stretchable temple 100 of this utility model.

[0025] like Figure 1 As shown, the extendable temple 100 includes: a hinge assembly 10, a temple 20, and an adjustment assembly 30, wherein, as Figures 3 to 4 As shown, the hinge assembly 10 has a hinge leg 11, and the temple 20 has a groove 211 extending along its own length. The adjustment assembly 30 includes an adjusting member 31 and a positioning member 32. The adjusting member 31 has a first end and a second end. The first end is connected to the hinge leg 11, and the second end is slidably disposed in the groove 211. The adjusting member 31 has a plurality of positioning holes 381 spaced apart along its own sliding direction. Adjacent positioning holes 381 are connected by a transition channel 382. The positioning member 32 is installed on the temple 20 and can selectively engage with any one of the positioning holes 381 to fix the position of the hinge assembly 10 relative to the temple 20. When it is necessary to adjust the length of the temple 20, the adjusting member 31 can slide relative to the temple 20 to adjust the position of the hinge assembly 10 relative to the temple 20. The component 31 switches between adjacent positioning holes 381 via the transition channel 382. By using the adjustment component 31 to slide within the groove 211 of the temple 20, and cooperating with the positioning component 32 to selectively engage with different positioning holes 381, the length of the temple 20 can be adjusted in multiple positions to meet the needs of different wearers. The adjacent positioning holes 381 are connected by the transition channel 382, ​​making the adjustment component 31 smoother when switching positioning holes 381 and simplifying the adjustment operation. At the same time, the cooperation between the positioning component 32 and the positioning hole 381 ensures the structural stability after adjustment, preventing the temple 20 from loosening during use, thereby increasing the convenience of adjusting the length of the temple 20 and improving the wearing comfort of the glasses.

[0026] The following text, combined with Figures 1 to 4 Further explanation is provided regarding the aforementioned stretchable temple 100.

[0027] To improve the connection stability and installation accuracy of the hinge assembly 10 and the adjusting member 31, such as Figures 3 to 4As shown, the hinge assembly 10 also includes a connector 12. The hinge leg 11 is provided with a slot 111. The first end of the adjusting member 31 is inserted into the slot 111 and is provided with a fixing hole 351 communicating with the slot 111. The connector 12 is threadedly connected to the hinge leg 11 and passes through the fixing hole 351. The connector 12 is a screw. By providing a slot 111 on the hinge leg 11, inserting the first end of the adjusting member 31 into the slot 111, and threading the connector 12 through the fixing hole 351 to the hinge leg 11, the connection stability between the adjusting member 31 and the hinge leg 11 is increased through the slot 111. At the same time, it is also convenient to improve the installation accuracy and replacement convenience of the adjusting member 31, thereby achieving the purpose of improving the connection stability and installation accuracy of the hinge assembly 10 and the adjusting member 31.

[0028] To improve the stability of the positioning component 32, such as Figures 3 to 4 As shown, the temple 20 includes a temple body 21 and a fixing member 22. The temple body 21 is provided with a sliding groove 211. The fixing member 22 is located on the side of the temple body 21 away from the positioning member 32 and is connected to the positioning member 32. The fixing member 22 is a metal nut that cooperates with the positioning member 32. The fixing member 22 is located on the side of the temple body 21 away from the positioning member 32 and is threadedly connected to the positioning member 32, thereby enhancing the firmness of the positioning member 32 installation and preventing the positioning member 32 from loosening or falling off during long-term adjustment, thus achieving the purpose of improving the stability of the positioning member 32 in use.

[0029] To reduce the production cost of the adjusting component 31 and improve its user experience, such as... Figure 4 As shown, the adjusting component 31 includes a connecting part 35, a sliding part 36, and two elastic arms 37. The connecting part 35 is connected to the hinge leg 11. The sliding part 36 is slidably disposed in the slide groove 211. The two elastic arms 37 are spaced apart, with one end of each elastic arm 37 connected to the connecting part 35 and the other end connected to the sliding part 36. A hollow area 38 is formed between the two elastic arms 37. The hollow area 38 constitutes a positioning hole 381 and a transition channel 382 connecting adjacent positioning holes 381. The hollow area 38 between the two elastic arms 37 simplifies the structure of the adjusting component 31 and facilitates its processing and manufacturing. The setting of the elastic arms 37 enables the adjusting component 31 to have a certain elastic deformation capability during the sliding adjustment process, which helps the positioning component 32 to switch between different positioning holes 381. At the same time, it can also improve the tightness of the fit between the positioning component 32 and the positioning hole 381, thereby reducing the production cost of the adjusting component 31 and improving the user experience of the adjusting component 31.

[0030] To make the adjusting member 31 more flexible during sliding adjustment, such as Figure 4As shown, the hollow area 38 is also provided with a first movable hole 383 and a first dividing hole 384. The first movable hole 383 is located between the connecting part 35 and the positioning hole 381 adjacent to the connecting part 35. The first dividing hole 384 connects the positioning hole 381 and the first movable hole 383. By setting the first movable hole 383 and the first dividing hole 384 between the connecting part 35 and the adjacent positioning hole 381, the first movable hole 383 can provide a larger deformation space for the elastic arm 37, so as to make the adjusting member 31 more flexible when sliding.

[0031] Furthermore, to make the sliding adjustment of the adjusting component 31 smoother, such as... Figure 4 As shown, the hollow area 38 is also provided with a second movable hole 385 and a second dividing hole 386. The second movable hole 385 is located between the sliding part 36 and the positioning hole 381 adjacent to the sliding part 36. The second dividing hole 386 connects the positioning hole 381 and the second movable hole 385. The second movable hole 385 and the second dividing hole 386 are provided between the sliding part 36 and the adjacent positioning hole 381. The second movable hole 385 further increases the deformation space of the elastic arm 37, so as to make the sliding adjustment of the adjusting member 31 smoother.

[0032] To improve the switching stability of positioning component 32, such as Figure 4 As shown, the elastic arm 37 and the side wall of the slide 211 are spaced apart to form an extension space 387. The elastic arm 37 and the side wall of the slide 211 are spaced apart to form an extension space 387, which provides sufficient space for the deformation of the elastic arm 37, avoids interference between the elastic arm 37 and the side wall of the slide 211 during the deformation process, and achieves the purpose of improving the switching stability of the positioning component 32.

[0033] To improve the smoothness of switching of positioning component 32, such as Figure 3 As shown, the positioning component 32 includes a connecting end 321 and an adjusting end 322. The connecting end 321 is threadedly connected to the temple 20. The adjusting end 322 has a circular cross-section, and the positioning hole 381 is a circular hole that mates with the adjusting end 322. The connecting end 321 of the positioning component 32 is threadedly connected to the temple 20, which facilitates the installation and removal of the positioning component 32. The adjusting end 322 has a circular cross-section, and the positioning hole 381 is a circular hole that mates with it, making the fit between the positioning component 32 and the positioning hole 381 tighter and the positioning effect better. It also facilitates the sliding of the positioning component 32 within the transition channel 382, ​​thereby improving the smoothness of the switching of the positioning component 32.

[0034] To enhance the positioning stability of positioning hole 381, such as Figure 4As shown, the transition channel 382 gradually narrows away from the positioning hole 381, so that the guide positioning member 32 can slide smoothly along the transition channel 382 when switching the positioning hole 381, reducing the resistance during the adjustment process. At the same time, it can also provide a certain limiting effect after the positioning member 32 enters the positioning hole 381, thereby enhancing the positioning stability of the positioning hole 381.

[0035] A pair of glasses includes a frame and any of the above-mentioned extendable temples 20. The frame is hinged to a hinge assembly 10. Because it includes the aforementioned extendable temples 20, the length of the temples 20 can be flexibly adjusted according to the wearer's head shape and facial contours, thereby improving the wearing comfort and stability of the glasses and enhancing their applicability and practicality.

[0036] When the length of the temple 20 needs to be extended, the wearer can hold the end of the temple 20 and the hinge leg 11 of the hinge assembly 10 and apply a pulling force in the opposite direction. At this time, the sliding part 36 of the adjusting member 31 slides along the slide groove 211 of the temple 20, and the adjusting end 322 of the positioning member 32 disengages from the current positioning hole 381 and slides into the next adjacent positioning hole 381 through the transition channel 382. Since the transition channel 382 gradually contracts away from the positioning hole 381, and the elastic arm 37 forms an extension space 387 with the side wall of the slide groove 211, the elastic arm 37 will produce a slight elastic deformation during the adjustment process, ensuring that the positioning member 32 switches smoothly and realizes the length adjustment of the temple 20. When the length of the temple 20 needs to be shortened, the operation method is the reverse of the extension process.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
