Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses technology, and in particular to an adjustable eyeglass frame structure and eyeglasses. Background Technology
[0002] Traditional eyeglass frames generally use a fixed temple design, and their overall width cannot be adaptively adjusted according to the user's facial bone features, meaning that the distance between the left and right frames cannot be adjusted according to the user's face width.
[0003] Although existing technologies employ hinged temple expansion structures (such as increasing the angle between the temples and the frame) to adapt to different face shapes, the following problems still exist: hinge adjustment can only achieve a limited angle of expansion at the ends of the temples, and the main body of the frame still clamps too tightly on the user's cheekbones and temples. If worn for a long time, the continuous pressure of the main body of the frame on the soft tissue area will lead to facial indentations, obstructed blood circulation, and other discomfort, seriously affecting the user's wearing experience.
[0004] Therefore, there is an urgent need for an eyeglass frame or glasses that can adjust the distance between the left and right frames to improve the user's wearing experience. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable eyeglass frame structure that can adjust the spacing between the left and right frames, thereby improving the user's wearing experience.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] An adjustable eyeglass frame structure, comprising:
[0008] Left frame;

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0034] This disclosure provides an adjustable-pitch eyeglass frame structure, including a left frame, a right frame, and a nose bridge mount. The nose bridge mount is located between the left frame and the right frame. The end of the left frame adjacent to the nose bridge mount is slidably inserted into the nose bridge mount, and the end of the right frame adjacent to the nose bridge mount is also slidably inserted into the nose bridge mount.
[0035] Please see Figures 1 to 6 To better understand the adjustable-pitch frame structure 10 of this application, the following further explanation of the adjustable-pitch frame structure 10 is provided:
[0036] One embodiment of the adjustable-pitch eyeglass frame structure 10 includes a left frame 100, a right frame 200, and a nose bridge 300. The nose bridge 300 is located between the left frame 100 and the right frame 200. The end of the left frame 100 adjacent to the nose bridge 300 is slidably inserted into the nose bridge 300, and the end of the right frame 200 adjacent to the nose bridge 300 is slidably inserted into the nose bridge 300.
[0037] In this embodiment, by slidingly inserting the left frame 100 and the right frame 200 into the two ends of the nose bridge frame 300, the left frame 100 and the right frame 200 can be connected to the nose bridge frame 300 through insertion, while simultaneously achieving a sliding and telescopic function, thereby achieving the purpose of adjusting the distance between the left frame 100 and the right frame 200. The adjustable-distance frame structure 10 of this utility model can adjust the distance between the left and right frames 200 to accommodate different users' face widths, effectively reducing excessive pressure on the user's cheekbones and temples, and effectively avoiding discomfort such as facial pressure marks, thus improving the user's wearing experience.
[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the nose bridge support 300 has a sliding guide groove 301. The end of the left eyeglass frame 100 adjacent to the nose bridge support 300 is slidably inserted into the sliding guide groove 301, and the end of the right eyeglass frame 200 adjacent to the nose bridge support 300 is also slidably inserted into the sliding guide groove 301. This allows the left eyeglass frame 100 and the right eyeglass frame 200 to be connected to the nose bridge support 300 via insertion, while simultaneously achieving a sliding and telescopic function, thereby adjusting the distance between the left eyeglass frame 100 and the right eyeglass frame 200.
[0039] Specifically, in this embodiment, the sliding guide groove 301 is formed on the nose bridge frame 300, and the left frame 100 and the right frame 200 are slidably connected to the nose bridge frame 300 through the sliding guide groove 301. In other embodiments, the sliding guide groove 301 can also be formed separately at one end of the left frame 100 adjacent to the nose bridge frame 300 and at one end of the right frame 200 adjacent to the nose bridge frame 300. In this case, the two ends of the nose bridge frame 300 can respectively form corresponding sliding protrusions, which are slidably connected to the corresponding sliding guide groove 301 on the left frame 100 and the corresponding sliding guide groove 301 on the right frame 200, thereby achieving the same sliding connection effect as in this embodiment.
[0040] like Figure 3 As shown, in one embodiment, the sliding guide groove 301 extends through both ends of the nose bridge support 300. In one embodiment, the left frame 100 has a first sliding insertion portion 110 formed near the end of the nose bridge support 300, and the first sliding insertion portion 110 is slidably disposed in the sliding guide groove 301; the right frame 200 has a second sliding insertion portion 210 formed near the end of the nose bridge support 300, and the second sliding insertion portion 210 is slidably disposed in the sliding guide groove 301.
[0041] It is understandable that by setting different length values for the first sliding part 110, the sliding and telescopic distance of the left frame 100 relative to the bridge of the nose 300 is different; similarly, by setting different length values for the second sliding part 210, the sliding and telescopic distance of the right frame 200 relative to the bridge of the nose 300 is different, and finally the first sliding part 110 and the second sliding part 210 slide and telescopic from both ends of the bridge of the nose 300 respectively.
[0042] like Figure 3As shown, in one embodiment, the adjustable-pitch frame structure 10 further includes a back plate 400. A portion of the back plate 400 covers the opening of the sliding guide groove 301 facing the bridge of the nose, and another portion of the back plate 400 is detachably connected to the nose bridge support 300. The back plate 400 is used to limit and press the first sliding insert 110 and the second sliding insert 210. Thus, after the first sliding insert 110 and the second sliding insert 210 are slidably disposed in the sliding guide groove 301, the back plate 400 covering the opening of the sliding guide groove 301 facing the bridge of the nose forms a limiting installation of the first sliding insert 110 and the second sliding insert 210, preventing the first sliding insert 110 and the second sliding insert 210 from falling off, and simultaneously improving the sliding stability of the first sliding insert 110 and the second sliding insert 210.
[0043] For example, 3 to Figure 5 As shown, in one embodiment, the back panel 400 has a first step 410 protruding at one end adjacent to the left frame 100, and a second step 420 protruding at one end adjacent to the right frame 200; the end of the first sliding part 110 has a first anti-slip buckle 1110 protruding, and the end of the second sliding part 210 has a second anti-slip buckle 2110 protruding, the first anti-slip buckle 1110 and the first step 410 are offset from each other, and the second anti-slip buckle 2110 and the second step 420 are offset from each other.
[0044] It is understood that in this embodiment, when the first sliding part 110 slides away from the nose bridge support 300, because the first anti-slip buckle 1110 and the first step 410 are misaligned, and after the first sliding part 110 has slid away to its maximum distance, the first anti-slip buckle 1110 will abut against the first step 410, thereby preventing the first sliding part 110 from sliding further. That is, the setting of the first step 410 forms a sliding limit on the first sliding part 110, so as to effectively prevent the first sliding part 110 from sliding away. Sliding and falling off; Similarly, when the second sliding part 210 slides away from the bridge of the nose 300, because the second anti-slip buckle 2110 and the second step 420 are misaligned, and after the second sliding part 210 slides away to the maximum distance, the second anti-slip buckle 2110 will abut against the second step 420, thereby preventing the second sliding part 210 from sliding further. That is, the setting of the second step 420 forms a sliding limit on the second sliding part 210, so as to effectively prevent the second sliding part 210 from sliding and falling off.
[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the back plate 400 is screwed or snapped to the nose bridge bracket 300.
[0046] It is understood that, specifically, in this embodiment, a portion of the back plate 400 mainly covers the opening of the sliding guide groove 301 facing the bridge of the human nose, while the other portion of the back plate 400 is locked to the bridge of the nose bracket 300 by screws, facilitating the disassembly and assembly of the back plate 400 and ensuring reliable connection. Of course, in one embodiment, the back plate 400 can also be fixedly installed by snap-fit.
[0047] like Figure 2 and Figure 3 As shown, in one embodiment, the nose bridge support 300 forms a limiting part 310 on one side of the sliding guide groove 301, and the limiting part 310 abuts against the back of the back plate 400 in a misaligned manner.
[0048] It is understood that another part of the back panel 400 has been locked to the nose bridge bracket 300 by screws. In this way, the limiting part 310 is misaligned and abuts against the back of the back panel 400, thereby firmly limiting the other part of the back panel 400 to ensure the installation stability of the back panel 400.
[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the nose bridge frame 300 has a nose pad 320 facing the bridge of the nose. Thus, the nose pad 320 provides support for the glasses frame.
[0050] Please refer to the following: Figures 1 to 6 This application also provides a pair of eyeglasses, including a left lens 500, a right lens 600, a left temple 700, a right temple 800, and the adjustable-pitch frame structure 10 described in any of the above embodiments. The left lens 500 is fixedly installed on the left frame 100, the right lens 600 is fixedly installed on the right frame 200, the left temple 700 is hinged to the left frame 100, and the right temple 800 is hinged to the right frame 200.
[0051] In this embodiment, by sliding and inserting the left and right frames into the two ends of the nose bridge frame respectively, the left and right frames can be connected to the nose bridge frame through insertion, and at the same time, the sliding and telescopic function is realized. This achieves the purpose of adjusting the distance between the left and right frames to adapt to the face width of different users, effectively reducing the excessive clamping of the overall frame on the user's cheekbones and temples, and effectively avoiding discomfort such as facial pressure marks, thus improving the user's wearing experience.
[0052] Furthermore, the eyeglasses adopt the aforementioned adjustable-gap frame structure, which allows eyeglass manufacturers to reduce the mold manufacturing costs for left and right frames of different sizes and specifications, effectively reducing mold production costs.
[0053] Compared with the prior art, the present invention has at least the following advantages:
[0054] By sliding and inserting the left and right frames respectively into the two ends of the nose bridge frame, the left and right frames can be connected to the nose bridge frame through insertion, while also achieving a sliding and telescopic function, thereby adjusting the distance between the left and right frames. This adjustable frame structure allows for adjustment of the distance between the left and right frames to accommodate different face widths, effectively reducing excessive pressure on the cheekbones and temples, and avoiding discomfort such as facial pressure marks, thus improving the user's wearing experience.
[0055] 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.
