Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to an anti-pressure mark nose pad. Background Technology

[0002] Nose pads are an indispensable part of eyeglasses, primarily serving to reduce pressure on the bridge of the nose from the frames. Various types of nose pads are available, with silicone nose pads being the most effective at preventing pressure marks compared to other types. Specifically, their structure generally includes a frame and a silicone pad placed outside the frame through vulcanization, coating, or other methods. The silicone pad increases the contact area with the wearer's face while utilizing its own elasticity to reduce localized pressure.

[0003] However, according to existing technology, nose pads are generally arranged at an angle to fit the wearer's nose bridge skin. Therefore, when actually wearing glasses, the area with the greatest force is often the lower end of the nose pad. Even with silicone pads, it is still inevitable that pressure marks will be caused on the user's nose bridge after wearing glasses for a long time. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an anti-indentation nose pad. The technical problem this invention aims to solve is: how to alleviate the indentations that form on the bridge of the user's nose when wearing glasses.

[0005] The purpose of this utility model can be achieved through the following technical solution: an anti-indentation nose pad, comprising a body made of elastic material, characterized in that the width of the body gradually increases from the upper end to the lower end, a weakening groove is provided on the outer side of the body, the weakening groove is located near the lower end of the body, and the weakening groove penetrates through the two edges of the outer side of the body.

[0006] This anti-indentation nose pad includes a main body, specifically made of elastic material, such as silicone as in existing technology. Notably, to ensure structural stability, a metal or plastic frame can be incorporated within the main body. The main body is fixed to this frame via vulcanization molding. During assembly, the outer surface of the main body is bonded to the eyeglass frame, while the inner surface contacts the user's nose bridge skin. The difference between this application and existing technology lies in the following: This application first adjusts the shape of the main body, using a structure that is wider at the bottom than the top, instead of the elliptical structure of existing technology. This effectively increases the contact area between the lower end of the main body and the user's nose bridge during wear, thereby minimizing pressure on the user's nose. To address the pressure at the bridge of the nose, this application addresses this issue by creating a weakening groove on the outer surface of the main body. This groove is specifically located near the lower end of the main body and extends through both edges of the outer side of the main body. The presence of this weakening groove enhances the deformability of the lower end of the main body. In other words, when a user wears glasses, the force applied to the user's nose bridge by the main body forces the lower end of the main body to deform more fully. Under the premise that the pressure on the skin at the bridge of the nose remains unchanged, the lower end of the main body and the inner surface of the main body near the lower end work together to apply force to the skin at the user's nose bridge. In addition, the deformation length of the main body is stretched to a certain extent when it bends and deforms. By increasing the contact area, the pressure is reduced, thereby alleviating the pressure marks formed on the user's nose bridge when wearing glasses.

[0007] In the aforementioned anti-indentation nose pad, the bottom wall of the weakening groove is arc-shaped. This design increases the deformation coefficient of the lower end of the body, allowing the lower end of the body to undergo elastic deformation more easily.

[0008] In the aforementioned anti-indentation nose pad, the lower end of the main body is curved outwards and has an arc shape. This structural design, combined with the weakening groove on the outer surface of the main body, further ensures that the lower end of the main body can deform more easily during wear. Furthermore, because the lower end of the main body is arc-shaped, it can fully conform to the skin of the user's nose bridge, providing more thorough contact.

[0009] In the aforementioned anti-indentation nose pad, the inner surface of the main body is arc-shaped, and the inner surface of the main body and the circumferential edge of the main body form an arc transition. This ensures sufficient contact area with the user's nose bridge skin while preventing indentations caused by excessive pressure in certain areas through a smooth arc transition.

[0010] In the aforementioned anti-indentation nose pad, the main body has a positioning protrusion on one side of the weakening groove, and the positioning protrusion protrudes downward from the upper edge of the weakening groove. This positioning protrusion is mainly used to connect with the frame, serving as a connection positioning point, which ensures installation accuracy while enabling quick installation of the main body.

[0011] Compared with existing technologies, this anti-indentation nose pad has the following advantages:

[0012] The main body is a long, strip-shaped piece that gradually increases in width from top to bottom. A weakening groove is cut on the outer side of the lower end, running through both edges. While ensuring the contact area between the lower end of the main body and the user's nose bridge skin, the presence of the weakening groove allows the lower end of the main body to more easily deform elastically. This allows the lower end of the main body to fit snugly against the user's nose bridge with its inner side, thereby increasing the contact area and reducing pressure. This minimizes the pressure marks that may form on the user's nose bridge during wear. Attached Figure Description

[0016] In the figure, 1 is the main body; 11 is the weakening groove; and 12 is the positioning protrusion. Detailed Implementation

[0017] 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.

[0018] like Figs. 1-3 As shown, this anti-indentation nose pad includes a body 1, which is made of silicone material. In addition, this anti-indentation nose pad also includes a skeleton made of metal or plastic material. The body 1 is vulcanized and molded outside the skeleton. The body 1 is specifically in the shape of a long strip and is set vertically. The width of the body 1 gradually increases from the top to the bottom.

[0019] like Figs. 1-3 As shown, a weakening groove 11 is provided on the outer side of the main body 1. The weakening groove 11 is located near the lower end of the main body 1 and extends through both sides of the outer side of the main body 1. The bottom wall of the weakening groove 11 is arc-shaped. The lower end of the main body 1 is bent outward and the outer wall of the lower end of the main body 1 is arc-shaped. The inner side of the main body 1 is an outwardly protruding arc-shaped surface. The inner side of the main body 1 and the circumferential edge of the main body 1 form an arc transition.

[0020] like Figs. 1-3As shown, the outer wall of the body 1 has a positioning protrusion 12. The outer wall of the positioning protrusion 12 is arc-shaped and protrudes downward from the upper edge of the weakening groove 11. It is worth mentioning that the skeleton is prior art, and its shape is not limited in this embodiment. However, it should be emphasized that in order to ensure that the body 1 in this application has sufficient elastic deformation capability, the skeleton is set near the upper end of the body 1, and the lowermost end of the skeleton must not protrude from the lower edge of the positioning protrusion 12.

[0021] During installation, the manufacturer only needs to align the positioning protrusion 12 with the frame mounting part and assemble it by means of heat fusion or bonding. When wearing the glasses, due to the weight of the glasses themselves, especially the weight of the frame and lenses, when the main body 1 comes into contact with the user's nose bridge, the lower end of the main body 1 can be appropriately deformed outward due to the presence of the weakening groove 11 and the mounting posture of the main body 1. While the lower end face of the main body 1 contacts the user's nose bridge skin, the inner side of the lower end of the main body 1, together with the lower end face of the main body 1, presses against the user's nose bridge skin, thereby reducing the pressure in the local area and maximizing the relief of pressure marks formed on the user's nose bridge when wearing glasses.
