Technical Field
[0001] This utility model pertains to structural components of non-optical eyeglasses, specifically a connection structure between the eyeglass head and temple, and an eyeglass frame. Background Technology
[0002] In current technology, the thinness and lightness of eyeglasses is a goal pursued by eyeglass designers and manufacturers. Achieving this goal primarily involves making both the optical lenses and the lens-holding structure (eyeglass frames) thinner. The design of thinner eyeglass frames generally starts with improvements to the materials and structure of the frames and temples. For example, using polymer materials or titanium-containing metals for the frames and titanium-containing metals for the temples, and then further designing the structure to improve strength.
[0003] Due to their structural characteristics, the design of eyeglass frames remains limited to the traditional hinge structure. Although some eyeglass frames utilize the inherent toughness of metal / non-metal materials to fold the temples, employing a non-hinge structure, the materials used in these frames / temples to achieve the required structural strength are very expensive.
[0004] In the existing technology, the materials of eyeglass frames are mainly divided into metals and non-metals. Metal materials are mostly titanium-containing metals or alloys, while non-metals are mostly high-polymer materials TR90 (Grilamid TR90). Summary of the Invention
[0005] To address the aforementioned problems in the existing technology, this utility model proposes a connection structure between the temple and the head of an eyeglass, as well as a thin eyeglass frame using this structure, as detailed below:
[0006] A connection structure between the head and the temple of a pair of glasses, defining the side of the head facing the human eye as the back, the side away from the human eye as the front, the side of the head closer to the frame as the inner side, and the side farther from the frame as the outer side.
[0007] The back of the pile head has a boss, and inside the boss is a groove. The opening end of the groove faces the side of the human eye. The inner cavity of the groove is partially spherical, with the center of the sphere inside the groove. The distance from the center of the sphere to the bottom of the groove is greater than the distance from the center of the sphere to the top surface of the groove.
[0008] A spherical structure is connected to the end of the temple, and the radius of the spherical structure corresponds to the radius of the sphere inside the groove.
[0009] The spherical structure of the temple is embedded in a groove, and the main body of the temple is located on the plane of the back of the head of the temple, around the center of the spherical structure.
[0010] In this structure, the spherical structure rotates within the groove. When the temples are retracted, they are close to the back of the headstock; when the temples are extended, they are away from the back of the headstock.
[0011] The rotation axis of the spherical structure passes through the center of the sphere, and the direction of the rotation axis is to make the temple and the back of the frame reach a reasonable angle (usually the back of the frame and the back of the frame are on the same plane). Ultimately, after the frame is fitted with the lens, the optical axis of the lens can ensure that the light can be correctly focused on the retina.
[0012] Furthermore, if the protrusion is made of metal or polymer, then a crack is opened on the side wall of the groove, and one end of the crack extends to the opening end of the groove; then the radius of the opening end of the groove after it expands due to the crack in the side wall of the groove is not less than the radius of the spherical structure.
[0013] Alternatively, if the protrusion is made of an elastic polymer material, the radius of the groove opening after expansion due to the elasticity of the polymer material will not be less than the radius of the spherical structure.
[0014] Of the two types of bosses mentioned above:
[0015] Metal bosses are mostly used for metal pile heads and are welded to the back of the pile head.
[0016] Polymer material bosses are mostly used for polymer material pile heads. The boss and pile head (or even the frame) are made by integrated injection molding process, or the boss and pile head can be connected by adhesive process.
[0017] Furthermore, it also includes a rotation limiting structure for a spherical structure, which includes: a limiting groove in the groove and a limiting block for the spherical structure;
[0018] The limiting groove is located below the bottom of the groove, with its opening at the bottom. The depth of the limiting groove is perpendicular to the axis of rotation of the spherical structure. The bottom surface of the limiting groove is arc-shaped, with the center of the arc on the axis of rotation of the spherical structure. The distance between the two end faces of the limiting groove is not greater than the diameter of the sphere within the groove cavity. The width between the two side walls of the limiting groove is not less than the thickness of the limiting block.
[0019] The limiting block protrudes below the bottom of the spherical structure; when the spherical structure is embedded in the groove, the limiting block is in the limiting groove; when the spherical structure rotates around its axis of rotation, the limiting block moves between the two end faces of the limiting groove.
[0020] Furthermore, a notch for placing the temple is opened on the inner side of the groove near the head of the post, and the opening end of the notch is coplanar with the opening end of the groove.
[0021] When the temples are retracted, the portion behind the spherical structure of the temples is within the notch. In this structure, the crack and the notch serve the same function; that is, the crack is equivalent to the notch, and there is no need to create a separate crack.
[0022] Furthermore, the spherical structure is composed of a metal skeleton encased in a polymer material; the metal skeleton is an extension of the temple end.
[0023] The further improved structure is as follows: the spherical structure is composed of a metal skeleton wrapped with a polymer material; the metal skeleton is a cross shape formed by two metal rods, the horizontal metal rod is an extension of the temple end, and the axis of the vertical metal rod is collinear with the rotation axis of the spherical structure.
[0024] Here, the polymer material and the metal surface, or the polymer material surface, both have a certain resistance effect, giving the spherical structure and the groove a certain degree of damping. The metal frame and its structural connection with the temples give the spherical structure high structural strength.
[0025] An eyeglass frame includes a frame, temples, and nose supports; the left and right parts of the frame are connected by a bridge of the nose, two nose supports are respectively connected to the lower part of the bridge of the frame, and nose pads are respectively connected to the two nose supports; the two temples are respectively rotatably connected to posts on both sides of the frame, and the connection structure between the posts and the temples adopts the aforementioned connection structure.
[0026] The frame and the pile head are an integral structure.
[0027] The frame and the pile head are made of the same material:
[0028] The frame and the head of the frame are made of metal, the boss is made of metal, and the boss is welded to the back of the head of the frame;
[0029] Alternatively, the frame and the head of the mirror are made of polymer materials, and the boss is also made of polymer materials; the frame, the head of the mirror, and the boss are an integrated injection-molded structure.
[0030] One possible structure is as follows: the nose support and nose pads are both made of polymer materials, and the frame, post, and protrusion are an integrated injection-molded structure (the nose support and nose pads can be the same integrated structure, or they can be independent structures connected to the frame).
[0031] In other implementations, the nose support and nose pads are implemented in other structural forms, and the resulting functions are consistent with those of the nose support / nose pads in eyeglass frames.
[0032] This technical solution utilizes a near-spherical groove at the head of the frame, which fits snugly against the spherical structure at the front of the temple, forming a stable and durable connection between the frame and temple. This structure eliminates the need for screws, relying solely on the compression between the two parts to achieve smooth opening and closing of the temple. It also achieves a lighter weight, easier maintenance, and longer service life compared to traditional hinge and screw structures. Attached Figure Description

[0043] The present invention will now be described in conjunction with the accompanying drawings and specific embodiments.
[0044] Referring to Figures 1 to 4, a connection structure between the head and the temple is described, where the side of the head 4 facing the human eye is defined as the back, the side facing away from the human eye is defined as the front, the side of the head 4 closest to the frame 1 is defined as the inner side, and the side furthest from the frame is defined as the outer side.
[0045] Further reference Figure 2 The back of the pile head 4 has a protrusion 5, and inside the protrusion is a groove 6. The opening end of the groove faces the side of the human eye. The inner cavity of the groove is partially spherical, and the center of the sphere is inside the groove. The distance from the center of the sphere to the bottom of the groove is greater than the distance from the center of the sphere to the top surface of the groove.
[0046] A spherical structure 7 is connected to the first end of the temple 2, and the radius of the spherical structure corresponds to the radius of the sphere inside the groove.
[0047] The spherical structure 7 of the temple is embedded in the groove 6, and the main body of the temple is close to or far from the back plane of the post head around the center of its spherical structure.
[0048] If the protrusion 5 is made of metal or polymer, then a crack is opened on the side wall of the groove, and one end of the crack extends to the opening end of the groove; then the radius of the opening end of the groove after it expands due to the crack in the side wall of the groove is not less than the radius of the spherical structure.
[0049] In this example, the protrusion 5 is made of an elastic polymer material, so the radius of the opening end of the groove after expansion due to the elasticity of the polymer material is not less than the radius of the spherical structure.
[0050] Referring further to Figures 3(a) to 3(c), it also includes a rotation limiting structure for the sphere structure, which includes: a limiting groove 8 in the groove 6 and a limiting block 9 in the sphere structure 7;
[0051] The limiting groove is located below the bottom of the groove, with its opening at the bottom. The depth of the limiting groove is perpendicular to the axis of rotation of the spherical structure. The bottom surface of the limiting groove is arc-shaped, with the center of the arc on the axis of rotation of the spherical structure. The distance between the two end faces of the limiting groove is not greater than the diameter of the sphere within the groove cavity. The width between the two side walls of the limiting groove is not less than the thickness of the limiting block.
[0052] The limiting block protrudes below the bottom of the spherical structure; when the spherical structure is embedded in the groove, the limiting block is in the limiting groove; when the spherical structure rotates around its axis of rotation, the limiting block moves between the two end faces of the limiting groove.
[0053] A notch 10 for placing the temple is opened on the inner side of the groove 6 near the head of the post. The opening end of the notch is coplanar with the opening end of the groove.
[0054] Referring further to Figures 4(a) and 4(b), in this example, both the upper and lower ends of the sphere structure are ground flat into planes (the axis of rotation passes perpendicularly through these two planes), and the corresponding parts of the groove are also ground flat. This structure makes the fit between the sphere structure and the groove more stable, that is, the axis of rotation is less likely to deviate at an angle, and it is easier to assemble the two.
[0055] The spherical structure 7 is composed of a metal frame encased in a polymer material; the metal frame is an extension of the temple 2.
[0056] As an optimized solution, in this example, the spherical structure 7 is composed of a metal skeleton encased in polymer material; the metal skeleton, formed by the intersection of two metal rods 11, has the horizontal metal rod extending from the head of the temple 2, and the axis of the vertical metal rod collinear with the rotation axis of the spherical structure. The main body of the temple in this example is made of metal.
[0057] Referring again to Figures 1(a) and 1(c), an eyeglass frame includes a frame 1, temples 2, and nose supports; the left and right parts of the frame are connected by a bridge 3, and two nose supports are respectively connected to the lower part of the bridge of the frame, with nose pads attached to each of the two nose supports; the two temples 2 are rotatably connected to posts 4 on both sides of the frame. The connection structure between the posts and the temples adopts the connection structure described above.
[0058] The frame 1 and the pile head 4 are an integral structure.
[0059] In this example, the frame and the post head are made of the same material:
[0060] One configuration involves the frame 1 and the post 4 being made of metal, and the boss 5 being made of metal, welded to the back of the post. Here, the metal can be titanium or a titanium alloy.
[0061] Another configuration involves the frame 1 and the nose bridge 4 being made of polymer materials, as are the nose support and nose pads, and the boss 5. The frame, nose bridge, and boss are a single injection-molded structure. Here, the polymer material can be TR90.
