Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to a hinge structure for eyeglasses. Background Technology

[0002] Eyeglasses are common optical devices in existing technology. They are mainly composed of two parts: lenses and frames. As the main part of the eyeglasses, the frames serve both to hold the lenses and to provide a place for the user to wear them, making them an indispensable part of eyeglasses.

[0003] Structurally, a complete eyeglass frame consists of a frame and two temples, as disclosed in Chinese Patent (Application Publication No.: CN103238100A), which is used to connect the temples and the frame. The frame can be composed of one or more frame components. The components of the eyeglasses (including the temples and frame) are replaceable, allowing for quick and easy changes to the color, shape, and style of the glasses. The temples are securely connected to the frame, but the connection method allows for easy removal and replacement. The temples need to deform, bend, or move beyond their normal orientation to allow for easy disconnection. In a preferred embodiment, the temple hinge assembly includes a hook element and a pivot, wherein the pivot includes a groove or cut-off portion positioned such that the hook element engages / disengages only when the temple is deformed or moves beyond its normal position.

[0004] According to paragraphs 0069 and 0076 of its specification, the hinge structure assembly of the eyeglasses disclosed therein consists of a first hinge element 21 and a second hinge element 22. The two hinges are engaged by a pivot 23 in the first hinge element 21 and a hook-shaped element 41 in the second hinge element 22, thereby allowing the second hinge element to rotate around the pivot of the first hinge element [excerpted from paragraph 0077 of the specification of CN103238100A].

[0005] However, in actual use, the sides of a user's head are not completely flat; instead, they are irregular surfaces with a certain degree of concavity and convexity. In contrast, the distance between the two temples remains constant. Therefore, during wear, the two temples are often squeezed by the user's face and excessively rotated outward relative to the hinge. Under this condition, the hinge is subjected to excessive force for a long time, which can easily lead to damage to the hinge assembly and render the frame unusable. Furthermore, the reaction force generated by the temples rotating outward will also act entirely on the user's face. Over time, this can cause pressure marks on the user's face, resulting in poor fit. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a hinge structure for eyeglasses. The technical problem this invention aims to solve is: how to improve the lifespan and adaptability of eyeglass frames.

[0007] The objective of this utility model can be achieved through the following technical solution: a hinge structure for eyeglasses, the eyeglasses including an eyeglass frame and temples, characterized in that the hinge structure includes a body in the shape of a long strip and made of an elastic alloy material, one end of the body being a fixed end connected and fixed to the eyeglass frame, and the other end being a hinge end hinged to the temples, the body having a front deformation portion and a rear deformation portion formed adjacent to each other by bending between the two ends, a deformation groove being formed on the body between the front deformation portion and the rear deformation portion, and the curvatures of the front deformation portion and the rear deformation portion being different.

[0008] In the hinge structure of this pair of glasses, the elongated body is connected and fixed to the eyeglass frame via a fixed end at one end, and hinged to the temple at the other end, thus connecting the eyeglass frame and the temple. The body is made of metal. There are generally two methods for connecting to the eyeglass frame: if the eyeglass frame is made of plastic and has a slot on its surface, the fixed end can be fixed by snapping into the slot; if the eyeglass frame is made of metal, the fixed end can be welded to the eyeglass frame. Furthermore, in this application, the body itself is made of an elastic alloy material. With the presence of a front deformation section and a rear deformation section, it can maintain high structural strength while possessing considerable elasticity. That is, when the temple is subjected to an outward-flipping compressive force, the front and rear deformation sections can elastically deform accordingly. This design unloads the pressure acting on the temples of the glasses, preventing damage to the hinge between the temples and the frame due to prolonged excessive pressure. The elastic cushioning also reduces the pressure exerted on the user's face by the temples, preventing pressure marks and improving fit. Furthermore, the front and rear deformation sections have different curvatures. Under stress, they can bend and deform appropriately according to their own curvature, dispersing the pressure. The deformation grooves between them work together to ensure more uniform elastic deformation in the middle section of the frame, preventing concentrated deformation in one area and avoiding bending or breakage due to prolonged stress.

[0009] In the aforementioned hinge structure of the eyeglasses, the curvature of the front deformation portion is less than that of the rear deformation portion. This design allows the rear deformation portion, which is closer to the temple, to deform preferentially than the front deformation portion, which is closer to the frame, when subjected to force. Furthermore, the rear deformation portion deforms more significantly than the front deformation portion, thus reducing the pressure exerted on the user's face and preventing pressure marks during prolonged wear. This also improves the fit for people with different head sizes.

[0010] In the hinge structure of the aforementioned eyeglasses, the body is made of titanium alloy. Alternatively, the body can also be made of nickel-titanium alloy.

[0011] In the hinge structure of the aforementioned eyeglasses, the fixed end is prism-shaped, and its two outer walls have several outwardly protruding latching portions, which are spaced apart along the axial direction of the fixed end. After the fixed end engages with the slot on the eyeglass frame, the latching portions on its outer wall ensure a tighter connection between the fixed end and the slot wall, thus guaranteeing connection strength.

[0012] In the hinge structure of the aforementioned eyeglasses, a hinge groove is provided at the end of the hinge, and hinge holes are provided on the outer walls on both sides of the hinge end, with both hinge holes communicating with the hinge groove. The hinge joint at the front end of the temple can be inserted into the hinge groove, and then a screw is passed through one of the hinge holes, the hinge joint, and the other hinge hole in sequence, and tightened with a nut, thereby completing the hinge connection between the body and the temple.

[0013] Compared with existing technologies, the hinge structure of these glasses has the following advantages:

[0014] By bending the main body between its two ends to form a front deformation section and a rear deformation section with different curvatures, and forming a deformation groove between the front and rear deformation sections, the front deformation section, the rear deformation section, and the deformation groove work together during use to unload the compressive force acting on the temples of the glasses through elastic deformation. This prevents the temples and the hinge of the glasses frame from being subjected to excessive pressure for a long time, effectively improving the service life of the glasses frame. At the same time, it reduces the pressure of the temples on the user's face and improves the adaptability of the glasses frame to different people. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 and Figure 2 As shown, in the hinge structure of this pair of glasses, the glasses include a frame 1 and two temples 2. The hinge structure includes a long, strip-shaped body 3 made of an elastic alloy material, specifically titanium alloy. Alternatively, it can be a nickel alloy. Figure 3 One end of the body 3 is a fixed end 31, and the other end is a hinge end 32. The fixed end 31 is used to connect and fix with the eyeglass frame 1, and the hinge end 32 is used to cooperate with the hinge and hinge with the temple 2.

[0021] Specifically, the fixing end 31 is in the shape of a quadrangular prism. Several outwardly protruding, beveled snap-fit ​​portions 311 are formed on the opposite outer walls of the fixing end 31. When the eyeglass frame 1 is made of plastic, a slot can be formed on the eyeglass frame 1. After the fixing end 31 is appropriately heated, it is snapped into the slot, so that the snap-fit ​​portion 311 and the slot wall are interference-fitted and fixed. When the eyeglass frame 1 is made of metal, the fixing end 31 and the eyeglass frame 1 can be directly welded together, thereby completing the connection and fixation between the body 3 and the eyeglass frame 1.

[0022] The hinge end 32 has a hinge groove 321 with an inner wall in the shape of an arc. The two outer walls of the hinge end 32 are both hinge holes 322. The two hinge holes 322 are externally opposite and connected to the hinge groove 321. When assembling the temple 2, the hinge joint at the front end of the temple 2 is inserted into the hinge groove 321, so that the pre-drilled hole on the hinge joint and the two hinge holes 322 are opposite to each other. Then, the screw is passed through one of the hinge holes 322, the pre-drilled hole on the hinge joint, and the other hinge hole 322 and tightened with a nut, thereby completing the hinge connection between the body 3 and the temple 2.

[0023] Combination Figure 3The front deformable portion 33 and the rear deformable portion 34 are bent between the two ends of the main body 3 and are distributed front and back. Both are located on one side of the main body 3 and have different curvatures. Specifically, the front deformable portion 33 is closer to the eyeglass frame 1 and the rear deformable portion 34 is closer to the temple 2. To meet the needs of use, the curvature of the rear deformable portion 34 is greater than that of the front deformable portion 33. Due to the presence of the front deformable portion 33 and the rear deformable portion 34, a V-shaped deformation groove 35 is formed on the main body 3 between the front deformable portion 33 and the rear deformable portion 34. The deformation groove 35 is located on the other side of the main body 3 relative to the front deformable portion 33 and the rear deformable portion 34.

[0024] When in use, the temple 2 is subjected to an outward pushing force. At this time, the rear deformation part 34 can undergo appropriate elastic deformation before the front deformation part 33. Then, due to the presence of the deformation groove 35, the structural strength of the body 3 located between the front deformation part 33 and the rear deformation part 34 is appropriately weakened, so that the deformation groove 35 and the front deformation part 33 can assist the rear deformation part 34 in undergoing appropriate deformation. The deformation of the three parts is used to appropriately offset the pushing force acting on the temple 2, thereby preventing the hinge from being over-pressed for a long time and breaking. Furthermore, as the pushing force acting on the temple 2 decreases, the pressure of the temple 2 acting on the user's face in the opposite direction can also be reduced. Therefore, when people with wider heads wear the glasses, the pressure marks caused by the temple 2 acting on the user's face can be reduced, thus improving the fit while ensuring the service life of the glasses frame.
