Description

Technical Field

[0001] The present invention belongs to the technical field of glasses manufacturing and relates to a nose pad bracket for glasses. Background Art

[0002] In the daily glasses wearing scenario, the nose pad bracket, as a core component of glasses, plays a decisive role in the wearing experience. However, traditional nose pad brackets have obvious deficiencies. Their height and angle are both fixedly set. For example, in a mounting structure of a glasses nose pad described in Chinese Patent No. "202421241169.1", in this patent, the clamping joint is aligned with the mounting hole, and a certain external force is applied to make the clamping joint pass through the mounting hole, so that the nose pad part is embedded in the mounting groove, and then the nose pad can be fixedly connected to the mounting seat. However, the nasal bridge heights and nasal profiles of different individuals vary greatly. The nose pad brackets with fixed specifications and fixed installations simply cannot adapt to such diverse nose shapes and are difficult to meet the wearing needs of different people. This results in many wearers having their glasses slide down frequently when using glasses for a long time, and they have to frequently manually straighten them, disrupting the normal activity rhythm. At the same time, the continuous discomfort is extremely likely to cause local compression pain on the nasal bridge, seriously reducing the wearing comfort. Summary of the Invention

[0003] The purpose of the present invention is to provide a nose pad bracket for glasses with adjustable height and angle in view of the above problems existing in the prior art.

[0004] The purpose of the present invention can be achieved by the following technical solutions: A nose pad bracket for glasses includes a bracket body and a nose pad. The bracket body includes a housing, a first folding slider and a second folding slider respectively hinged at both ends of the housing. The end of the first folding slider is connected to the nose pad through a universal joint. The end of the second folding slider is fixed to the spectacle frame. An elastic member is provided in the housing, and both ends of the elastic member are respectively connected to the first folding slider and the second folding slider. When the first folding slider or the second folding slider rotates relative to the housing, the elastic member deforms; when the bracket body is in a folded state or a fully stretched state, the elastic member returns to its original state.

[0005] In the above-mentioned nose pad bracket for glasses, two arc-shaped and opposite guiding grooves are formed on the side surface of the housing. Both ends of the elastic member are bent to form insertion rods. Corresponding insertion holes are formed on the first folding slider and the second folding slider. The insertion rods are inserted into the insertion holes. The part of the end of the insertion rod passing through the insertion hole is a guiding block. The two guiding blocks are respectively located in the two guiding grooves movably. When the bracket body is in a folded state or a fully stretched state, the two guiding blocks are respectively located at the ends on different sides of the two guiding grooves.

[0006] In the above-mentioned spectacle nose pad bracket, the housing includes a first side plate, a second side plate, a first limiting plate and a second limiting plate located at two ends of the first side plate. The guiding groove is located on the first side plate. When the first folding slider and the second folding slider rotate to contact the first limiting plate or the second limiting plate, the first folding slider and the second folding slider stop rotating.

[0007] In the above-mentioned spectacle nose pad bracket, when the bracket body is in a folded state, the first folding slider contacts the second limiting plate, and the second folding slider contacts the first limiting plate.

[0008] In the above-mentioned spectacle nose pad bracket, when the first folding slider is pulled outwards alone, the guiding block connected to the first folding slider moves synchronously, so that the guiding block moves to the other end of the guiding groove where it is located, that is, the two guiding blocks are respectively located at the same-side ends of the guiding groove where they are located. The elastic member deforms, and the end of the first folding slider contacts the first limiting plate. At this time, it is the first stretching state of the bracket body.

[0009] In the above-mentioned spectacle nose pad bracket, when the second folding slider is pulled outwards alone, the guiding block connected to the second folding slider moves synchronously, so that the guiding block moves to the other end of the guiding groove where it is located, that is, the two guiding blocks are respectively located at the same-side ends of the guiding groove where they are located. The elastic member deforms, and the end of the second folding slider contacts the second limiting plate. At this time, it is the second stretching state of the bracket body.

[0010] In the above-mentioned spectacle nose pad bracket, when both the first folding slider and the second folding slider are pulled outwards, the elastic member moves and deforms accordingly. The two guiding blocks respectively move to the other ends of the guiding grooves where they are located, that is, the two guiding blocks are respectively located at the ends on different sides of the two guiding grooves. The end of the first folding slider contacts the first limiting plate, and the end of the second folding slider contacts the second limiting plate. At this time, it is the fully stretched state of the bracket body.

[0011] In the above-mentioned spectacle nose pad bracket, the universal shaft includes two relatively arranged first connecting plates and two relatively arranged second connecting plates. The included angle between the first connecting plate and the second connecting plate is >90°. The first connecting plate is vertically arranged, and the second connecting plate is horizontally arranged. A first hinge shaft for hinging the first folding slider penetrates horizontally through the two first connecting plates, and a second hinge shaft for hinging the nose pad penetrates longitudinally through the two second connecting plates.

[0012] In the above-mentioned spectacle nose pad bracket, the elastic member is a spring steel wire.

[0013] In the above-mentioned spectacle nose pad bracket, the nose pad is circular, and the side surface of the nose pad is an arc surface.

[0014] In the above-mentioned spectacle nose pad bracket, the radius of curvature of the arc surface is 10 - 15 mm, the thickness of the nose pad is 1 - 2 mm, and the material of the nose pad is titanium alloy.

[0015] In the above-mentioned spectacle nose pad bracket, the second folding slider is fixed to the spectacle frame by welding.

[0016] Compared with the prior art, the spectacle nose pad bracket of the present invention has the advantages of high adjustability and free angle transformation, improving the comfort of wearing spectacles and greatly reducing the pressure on the bridge of the nose; users can rotate the first folding slider and / or the second folding slider according to their actual needs, and easily pull up and adjust the height of the nose pad bracket, so that the bracket body is stretched, fully covering the slight differences in the bridge of the nose height of different people; the nose pad is installed on the first folding slider through a universal joint, so that the nose pad can rotate relative to the first folding slider, and the nose pad can automatically and flexibly adjust to the best fitting angle, automatically fitting different nose shapes, improving the wearing fitting degree, ensuring that the spectacles are always firmly attached to the bridge of the nose, and fundamentally eliminating the problem of spectacle slipping.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The following are specific embodiments of the present invention in combination with the accompanying drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0023] As Figures 1-4As shown in the figure, the nose pad bracket of this pair of glasses includes a bracket body and a nose pad 5. The bracket body includes a housing 1, a first folding slider 2 and a second folding slider 3 respectively hinged at both ends of the housing 1. The end of the first folding slider 2 is connected to the nose pad 5 through a universal joint 4, and the end of the second folding slider 3 is fixed to the spectacle frame. An elastic member 6 is provided inside the housing 1. Both ends of the elastic member 6 are respectively connected to the first folding slider 2 and the second folding slider 3. When the first folding slider 2 or the second folding slider 3 rotates relative to the housing 1, the elastic member 6 deforms; until the bracket body is in the folded state or the fully stretched state, the elastic member 6 returns to its original state. The folded state described in the present invention specifically refers to the initial state before stretching, such as Figure 1 shown in the figure.

[0024] In the above technical solution: Two arc-shaped and opposite-facing guide grooves 11 are formed on the side surface of the housing 1. Both ends of the elastic member 6 are bent to form insertion rods. Corresponding insertion holes are formed on the first folding slider 2 and the second folding slider 3. The insertion rods are inserted into the insertion holes, so that the elastic member 6 is connected to the first folding slider 2 and the second folding slider 3. The part of the end of the insertion rod passing through the insertion hole is a guide block 61. The two guide blocks 61 are respectively located in the two guide grooves 11 movably. When the bracket body is in the folded state or the fully stretched state, the two guide blocks 61 are respectively located at the ends on different sides of the two guide grooves 11. In the specific folded state, one of the guide blocks 61 is located at the rightmost end of the guide groove 11, and the other guide block 61 is located at the leftmost end of the guide groove 11, such as Figure 1 shown in the figure; in the fully stretched state, one of the guide blocks 61 is located at the leftmost end of the guide groove 11, and the other guide block 61 is located at the rightmost end of the guide groove 11, such as Figure 3 shown in the figure.

[0025] In the above technical solution: The housing 1 includes a first side plate 12, a second side plate 13, and a first limiting plate 14 and a second limiting plate 15 located at both ends of the first side plate 12. The guide groove 11 is located on the first side plate 12. When the first folding slider 2 and the second folding slider 3 rotate to contact the first limiting plate 14 or the second limiting plate 15, the first folding slider 2 and the second folding slider 3 stop rotating.

[0026] Such as Figure 1The figure shows the folded state of the bracket body. The first folding slider 2 is in contact with the second limiting plate 15, and the second folding slider 3 is in contact with the first limiting plate 14. When the first folding slider 2 is pulled outwards alone, the guiding block 61 connected to the first folding slider 2 moves synchronously, so that the guiding block 61 moves to the other end of the guiding groove 11 where it is located, that is, the two guiding blocks 61 are respectively located at the same-side ends of the guiding grooves 11 where they are located (both are located at the left ends of the guiding grooves 11 where they are located), the elastic member 6 deforms, and the end of the first folding slider 2 is in contact with the first limiting plate 14. At this time, it is the first stretching state of the bracket body. When the second folding slider 3 is pulled outwards alone, the guiding block 61 connected to the second folding slider 3 moves synchronously, so that the guiding block 61 moves to the other end of the guiding groove 11 where it is located, that is, the two guiding blocks 61 are respectively located at the same-side ends of the guiding grooves 11 where they are located (both are located at the right ends of the guiding grooves 11 where they are located), the elastic member 6 deforms, and the end of the second folding slider 3 is in contact with the second limiting plate 15. At this time, it is the second stretching state of the bracket body. When both the first folding slider 2 and the second folding slider 3 are pulled outwards, the elastic member 6 moves and deforms accordingly. The two guiding blocks 61 respectively move to the other ends of the guiding grooves 11 where they are located, that is, the two guiding blocks 61 are respectively located at the ends on different sides of the two guiding grooves 11. The end of the first folding slider 2 is in contact with the first limiting plate 14, and the end of the second folding slider 3 is in contact with the second limiting plate 15. At this time, it is the fully stretched state of the bracket body, as Figure 3 shown. Through the traction force of the elastic member 6, the first folding slider 2 and the second folding slider 2 can be positioned in the folded state, the first stretching state, the second stretching state, and the fully stretched state, realizing four-stage height adjustment of the nose pad, with a wide application range and meeting the adjustment requirements of different users for the height of the nose pad.

[0027] In the above technical solution: The universal joint 4 includes two oppositely arranged first connecting plates 41 and two oppositely arranged second connecting plates 42. The included angle between the first connecting plate 41 and the second connecting plate 42 is > 90°. The first connecting plate 41 is vertically arranged, and the second connecting plate 42 is horizontally arranged. A first hinge shaft 43 for hinging the first folding slider 2 penetrates horizontally through the two first connecting plates 41, and a second hinge shaft 44 for hinging the nose pad 5 penetrates longitudinally through the two second connecting plates 42.

[0028] In the above technical solution: The elastic member 6 is a spring steel wire, specifically a high-elastic spring steel wire with a diameter of 0.4 mm, ensuring that when bearing the acting forces of the first folding slider 2 and the second folding slider 3, it can bend and deform smoothly and can also restore its original state stably, meeting the use requirements of long-term and frequent adjustment.

[0029] In the above technical solution: The second folding slider 3 is fixed to the spectacle frame by welding, making the bracket body a part of the glasses.

[0030] In the above technical solution: The nose pad 5 is circular, and the side surface of the nose pad 5 is an arc surface 51. The radius of curvature of the arc surface 51 is 10 - 15 mm, and the thickness of the nose pad 5 is 1 - 2 mm, which improves the fitting degree and comfort between the nose pad 5 and the nose bridge during wearing. The material of the nose pad 5 is titanium alloy, which is light in texture and has good biocompatibility, can reduce the burden on the nose bridge and lower the risk of allergy.

[0031] This glasses nose pad bracket has the advantages of highly adjustable height and freely changeable angle, which improves the comfort of wearing glasses and greatly reduces the pressure on the nose bridge; users can rotate the first folding slider 2 and / or the second folding slider 3 according to their actual needs, and easily pull up and adjust the height of the nose pad bracket, so that the bracket body is stretched, fully covering the slight differences in the nose bridge heights of different people; the nose pad 5 is installed on the first folding slider 2 through a universal joint 4, so that the nose pad 5 can rotate relative to the first folding slider 2, and the nose pad 5 can automatically and flexibly adjust to the best fitting angle, automatically fit different nose shapes, improve the wearing fitting degree, and ensure that the glasses are always firmly attached to the nose bridge, fundamentally eliminating the problem of the glasses slipping down.
