Description

Technical Field

[0001] The invention relates to the technical field of glasses, in particular to a pair of glasses with a high degree of face-fitting adaptability. Background Art

[0002] The same style of glasses from a sports eyewear manufacturer needs to be suitable for both round-headed and long-headed users.

[0003] There is a big difference in head circumference between the north and south of Chinese men, and between men and women. Therefore, eyewear manufacturers currently need to develop eyewear with different head circumferences to meet user wearing requirements, and the development cost and cycle are relatively large.

[0004] In order to prevent sports glasses from loosening from the wearing position and causing sports injuries during use, current solutions generally tend to achieve the purpose of wearing firmly by increasing the clamping force of the temples. In contrast, the wearing comfort of the solution is reduced and the wearing position may be damaged.

[0005] Currently, products on the market that increase the clamping force of the temples to make them fit more securely will cause the lenses of the products to deform to varying degrees, causing users to experience dizziness, blurriness and other adverse symptoms, affecting the user experience.

[0006] In the prior art, a pair of glasses with elastic temples is disclosed, and its authorization announcement number is CN202443198U. The temples are provided with elastic bending sections, and the elastic bending sections are configured as a tension spring structure. The materials of the elastic bending sections are different from those of other areas of the temples, so the temples and the tension spring assembly need to be connected by screws or other structures. The injection molding cost and the assembly cost are both high. The hair may get stuck during use, and the movable part may get stuck after wearing for a long time. Summary of the invention

[0007] The purpose of the present invention is to provide a pair of glasses with a high degree of face-fitting adaptability, so as to solve the problems in the prior art.

[0008] The object of the present invention is achieved in this way: a temple with high face adaptability, which includes a temple rod, on which one or more elastic deformation parts that can be elastically deformed in the left and right directions are provided, and the temple rod and its elastic deformation parts are integrally formed using the same material.

[0009] Furthermore, any cross-section of the temple rod is a structure that is wide at the top and narrow at the bottom.

[0010] Furthermore, the temple rod is installed with an elastic pad.

[0011] Furthermore, the elastic pad is installed in the main stress-bearing area of ​​the temple rod.

[0012] Furthermore, during wearing, the temple rod achieves a better fixed position within the range of the elastic pad after the elastic deformation part and the skull are balanced.

[0013] Furthermore, a hollow hole is provided at the rear of the temple rod, and the elastic pad is inserted into the hollow hole.

[0014] Furthermore, the elastic deformation portion is configured as a bent portion formed by bending in a curve from outside the skull to inside the skull.

[0015] Furthermore, the elastic deformation portion is thinner than other portions of the temple rod.

[0016] Furthermore, the temple rod is composed of a lens connecting part, a functional part, a transition connecting part, an elastic deformation part, and a rear fixing part, and the lens connecting part, the functional part, the transition connecting part, the elastic deformation part, and the rear fixing part are smoothly connected in sequence from front to back; the lens connecting part and the functional part can be relatively movably connected or fixedly connected; the functional part is opposite to the temple and the trigeminal nerve area, and maintains a certain distance between the temple and the trigeminal nerve area when worn; the transition connecting part protrudes toward the outside of the skull and protrudes downward to form a structural reinforcement part, and the elastic deformation part is elastically deformed left and right relative to the transition connecting part when worn; the rear fixing part is gradually thicker from front to back as a whole, and, along the direction from front to back, the lower side of the rear fixing part is gradually twisted inward relative to the upper side, and is in pressure contact with the surface of the skull to lock the position of the temple rod on the skull; the tail end of the rear fixing part is warped toward the outside of the skull.

[0017] As another aspect of the present invention, a pair of glasses is proposed, which includes a lens and two temples. The lens is arched forward as a whole, and the left and right ends of the lens are respectively fixedly connected to two temple rods, and together with the two temple rods, they form an elastic component for clamping the head.

[0018] The beneficial effects of the present invention are:

[0019] 1. The temples with elastic function can keep the deformation of the lens small while being compatible with users with round and long skulls, thereby expanding the use range of glasses;

[0020] 2. Through the redesigned wearing force points and elastic pads, the probability of the product being out of the use position due to strenuous exercise is reduced under the premise of lighter clamping force;

[0021] 3. Through the temples and their elastic deformation areas, the deformation caused by wearing is controlled within the elastic deformation part, effectively reducing the deformation of the lens;

[0022] 4. The entire temple rod is made of one material, which effectively improves production efficiency, yield rate and reduces production waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the attached embodiment of the present invention Figure 1-8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-2 As shown, a temple with high face adaptability is proposed, wherein an elastic deformation part 4 capable of elastic deformation in the left and right directions is provided on the temple rod, and the elastic deformation part 4 will produce adaptive deformation after contacting the surface of the skull, and the temple rod and its elastic deformation part 4 are integrally injection molded with the same material. During the production process, the temple rods are all integrally molded with the same material, without structural mutation, which can well guarantee the elastic function of the temple, the structural strength can be fully guaranteed, and the service life is longer.

[0034] Compared with conventional temples, the elastic temple rods are more deformed during use, and the temple rods can return to their original position when the temples are taken off.

[0035] It is worth mentioning that the above-mentioned structural type is not limited to only one, and the elastic deformation part 4 can be provided with one or more.

[0036] As an embodiment of structural optimization, there is also the following structural optimization scheme:

[0037] like Figure 3-5 As shown, any cross-section of the temple rod is a structure that is wide at the top and narrow at the bottom, similar to a melon seed shape, with a solid structure and both toughness and elasticity.

[0038] The above-mentioned temple rod is installed with an elastic pad, the material of the elastic pad is not limited here, such as TPU / TPE, or other elastic materials. The elastic pad is installed in the main force-bearing area of ​​the temple rod. During the wearing process, the temple rod makes the elastic deformation part 4 and the skull balance the two forces to obtain a better fixed position within the range of the elastic pad.

[0039] In order to facilitate the installation of the elastic pad, a preferred implementation scheme is: a hollow hole 5b is provided at the rear of the above-mentioned temple rod, and the elastic pad is inserted into the hollow hole 5b; the hollow hole 5b extends along the length direction of the temple rod to form a strip hole, and the structural form is not limited to the form listed in this embodiment.

[0040] The elastic deformation portion 4 is configured as a bent portion formed by bending from the outside of the skull to the inside of the skull. Figure 1 The elastic deformation portion 4 is a concave arc shape, and is thinner than other parts of the temple rod, that is, the elastic deformation portion 4 is the thinnest part, so that the elastic deformation portion 4 constitutes the elastic deformation zone of the temple rod.

[0041] As a preferred embodiment, the temple rod is composed of a lens connection part 1, a functional part 2, a transition connection part 3, an elastic deformation part 4, and a rear fixing part 5. The lens connection part 1, the functional part 2, the transition connection part 3, the elastic deformation part 4, and the rear fixing part 5 are smoothly connected in sequence from front to back. The elastic deformation part 4 and the rear fixing part 5 are in pressure contact with the skull, and the contact position will change adaptively with the specific skull shape of the user. This is a preferred embodiment, and other temple structure configurations can be extended based on the core design idea.

[0042] The lens connecting portion 1 and the functional portion 2 can be relatively movably connected or fixedly connected, that is, one of the connection modes can be selected; specifically, there are two connection schemes between the lens connecting portion 1 and the functional portion 2:

[0043] A. The lens connecting part 1 and the functional part 2 can be relatively movably connected. The lens connecting part 1 can be connected to the functional part 2 by a hinge (or other movable connecting parts / structures) for left and right rotation;

[0044] B. The lens connecting portion 1 and the functional portion 2 can be fixedly connected and can be integrally formed. The lens connecting portion 1 is bent inwardly relative to the functional portion 2 and can be detachably fixedly connected to the lens 6 (or the lens frame).

[0045] The functional part 2 is directly facing the temple and trigeminal nerve area, and maintains a certain distance from the temple and trigeminal nerve area when worn, leaving enough space to prevent compression of the temple and trigeminal nerve area, so as to protect the user's temple and trigeminal nerve area.

[0046] The transition connecting portion 3 protrudes toward the outside of the skull and protrudes downward to form a lower protrusion 3a (such as Figure 6 As shown), the structural strength of the connection between the functional part 2 and the elastic deformation part 4 is strengthened, so that the transition connection part 3 forms a structural reinforcement part; when worn, the elastic deformation part 4 elastically deforms left and right relative to the transition connection part 3. Since the structural strength of the transition connection part 3 is strengthened and the functional part 2 is obviously thicker than the elastic deformation part 4, the elastic deformation part 4 will not affect the functional part 2 when it is elastically deformed, that is, no matter how the elastic deformation part 4 is elastically deformed, the functional part 2 will not be affected.

[0047] The above-mentioned rear fixing part 5 as a whole gradually becomes thicker from front to back, and, along the direction from front to back, the lower side of the rear fixing part 5 is gradually twisted inward relative to the upper side, and the rear fixing part 5 contacts the surface of the skull with pressure (the contact point is located in the area of ​​the parietal bone near the junction of the parietal bone, temporal bone and occipital bone, and this patent may include the possibility of other contact points), locking the position of the temple rod on the skull.

[0048] In addition, the tail end of the rear fixing portion 5 is warped toward the outside of the skull, forming a tail end curved surface 5a on the inner side of the tail end of the rear fixing portion 5 that is in pressure contact with the skull. Such a design can facilitate the wearing process of the glasses. The tail end curved surface 5a at the tail ends of the two temple rods can play a guiding role in the process of wearing the glasses and is in smooth contact with the surface of the skull, so that the resistance during the wearing process is significantly reduced.

[0049] Furthermore, the rear fixing portion 5 is arched outward from the skull as a whole, so as to prevent the rear fixing portion 5 from pressing the ear area when worn, thereby ensuring wearing comfort.

[0050] The specific position of the above locking point can be flexibly changed according to the user's head shape.

[0051] like Figure 7 , 8As shown, the above-mentioned temple rod is installed on the glasses to form a preferred pair of glasses (this expression means that this is one of the structural configuration forms, and there will be other possible structural forms), which includes a lens 6 and two temples. The lens 6 is arched forward as a whole, and the left and right ends of the lens 6 are respectively fixedly connected to the two temple rods, and together with the two temple rods, it forms an elastically deformable component that elastically clamps the head; during the wearing process, the elastic deformation parts 4 of the two temple rods are adaptively deformed. Through the temples with elastic functions, the deformation caused by wearing is controlled within the elastic deformation part, effectively reducing the deformation of the lens. While keeping the deformation of the product lens small, it is compatible with users with round skulls and long skulls, thereby increasing the use range of the glasses.
