Abstract

This application discloses a nose pad and frame that are easy to assemble and disassemble, for mounting on a glasses frame. The nose pad includes a main body, which has an upper mounting protrusion and pad leaves on both sides of the mounting protrusion. The mounting protrusion has an insertion opening on the side facing away from the pad leaves. When the nose pad is mounted on the glasses frame, the mounting protrusion on the upper part of the nose pad can cover the connection between the nose pad and the glasses frame, so that the wearer will not directly contact the connection between the nose pad and the glasses frame when putting on or taking off glasses, achieving a wrap-around coverage and improving wearing comfort.

Description

Technical Field

[0001] This application relates to the technical field of eyeglasses, and in particular to a nose pad and frame that are easy to detach and assemble. Background Technology

[0002] Eyeglasses are widely used in daily life and are an indispensable tool for many people with poor vision. As an important part of eyeglasses, nose pads provide support for the wearer. In the past, to solve the problem of supporting the wearer, most nose pads on the market were made of PVC hard plastic or solid silicone. These traditional nose pads were directly installed on the frame of the eyeglasses to support them.

[0003] To improve wearing comfort and stability, existing technologies also attempt to use airbag-type nose pads. The main body of these nose pads is usually made of soft material, with two contact ends that come into contact with the person and a mounting end that is installed on the frame. Both contact ends are fixedly connected to the mounting end, which is generally made of rigid material and is fixed to the frame of the glasses by bolts.

[0004] While air-cushioned nose pads offer some improvement, the connection between the mounting end and the eyeglass frame is usually secured with bolts. The head or fixing part of the bolt is directly exposed and can easily come into contact with the wearer's nose bridge, which can seriously affect wearing comfort with long-term use. Summary of the Invention

[0005] To facilitate the installation and removal of airbag-type nose pads, a nose pad and frame that are easy to install and remove are provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A nose pad that is easy to install and remove, for use on a glasses frame, includes a nose pad body, the nose pad body includes an upper mounting protrusion and pad leaves disposed on both sides of the mounting protrusion, and the mounting protrusion has an insertion port on the side facing away from the pad leaves.

[0008] By adopting the above technical solution, when the nose pads are installed on the eyeglass frame, the mounting protrusion on the upper part of the nose pad body can cover the connection between the nose pad body and the eyeglass frame, so that the wearer will not directly contact the connection between the nose pad body and the eyeglass frame when putting on or taking off the glasses, thus achieving a wrap-around coverage and improving wearing comfort.

[0009] Preferably, the leaf portion has a insertion cavity communicating with the insertion port, and the outer wall of the leaf portion is connected to an air bladder portion communicating with the insertion cavity.

[0010] By adopting the above technical solution, the insertion cavity is a closed cavity, forming an elastic support that adapts to different nose bridge shapes and absorbs vibrations. When the airbag contacts the nose bridge, the internal air is compressed to form a flexible support that fits different nose contours, further improving the comfort of wearing the nose pad.

[0011] A glasses frame includes a nose pad that is easy to assemble and disassemble as described above; it also includes a connector for fixing to the frame, the connector being made of rigid material, including a support portion that passes through an insertion port and is inserted into a insertion cavity, and the cross section of the mounting protrusion facing the connector covers the connection between the connector and the frame.

[0012] By adopting the above technical solution, the supporting part of the connector passes through the insertion port and is inserted into the insertion cavity. With the help of the soft material nose pad body and the hard material connector, the nose pad body and the frame are connected in a way that is easy to disassemble and replace, making it convenient to disassemble and replace the nose pad body.

[0013] Preferably, the connector includes a fixing part that is fixed to the frame, and there are two support parts, which are respectively disposed on both sides of the fixing part. The mounting protrusion is provided with at least two insertion ports for the support parts to be inserted.

[0014] By adopting the above technical solution, the distribution of the support and fixing parts on both sides forms a triangular stable structure, which disperses the force on the nose pad and reduces the deformation of the frame. The nose pad body is installed by inserting and cooperating with the two support parts on the connector through at least two insertion ports on the mounting protrusion. Since the two support parts are respectively set on both sides of the fixing part and cooperate with the corresponding insertion ports, the nose pad can be installed more stably on the frame, reducing the possibility of the nose pad body slipping off.

[0015] Preferably, the two support portions extend in opposite directions.

[0016] By adopting the above technical solution, when the nose pad body is pulled out along the extension direction of the support part, the two opposing support parts form symmetrical force points, which can provide additional support for the nose pad body. The support parts at both ends form a wedge-shaped engagement with the pad leaf part, reducing the possibility of the nose pad body being accidentally pulled out in this extension direction, allowing the nose pad body to be firmly installed on the frame, ensuring that the nose pad body is installed stably and reliably, and further improving the comfort and stability of wearing.

[0017] Preferably, the outer wall of the support portion abuts against the inner wall of the insertion cavity.

[0018] By adopting the above technical solution, the interference fit generates positive pressure between the outer wall of the support part and the inner wall of the insertion cavity. The friction force is proportional to the positive pressure, which further enhances the tightness and stability of the connection between the nose pad body and the support part, avoids the nose pad from loosening or shaking, and reduces the risk of the support part slipping out of the insertion cavity.

[0019] Preferably, the support portion includes a connecting section and a support section, one end of the connecting section is connected to the fixing portion, the other end of the connecting section is connected to the support section, and the cross section of the support section perpendicular to its own extension direction is larger than the cross section of the connecting section perpendicular to the extension direction of the support section.

[0020] By adopting the above technical solution, the cross-section of the support section is larger than that of the connecting section, making the support section easier to deform than the connecting section. During disassembly and assembly, the support section deforms first, reducing the pull-out resistance and improving the convenience of nose pad disassembly and assembly. At the same time, the large cross-section support section disperses the pressure of the nose pad, avoiding excessive local pressure that could lead to material fatigue.

[0021] Preferably, the connecting segment and the support segment are connected by a guide slope.

[0022] By adopting the above technical solution, the guide slope design reduces the peeling force when the support is pulled out. Especially when the soft material comes into contact with the hard support, the slope can destroy the vacuum adsorption effect, making it easier to pull out the support and reducing the possibility of the nose pad body and the support getting stuck together, further improving the convenience and smoothness of nose pad assembly and disassembly.

[0023] Preferably, the connector further includes a limiting part connected between the support part and the fixing part, the outer wall of the limiting part being in contact with the inner wall of the insertion port, and the extending directions of the limiting part and the support part being different.

[0024] By adopting the above technical solution, the limiting part of the connector is connected between the supporting part and the fixing part. The outer wall of the limiting part fits with the inner wall of the insertion port to form a lateral limiting. When removing the nose pad body, it is necessary to first move the installation protrusion to disengage from the limiting part, and then pull it out along the setting direction of the supporting part. This reduces the possibility of the nose pad body being accidentally pulled out along the setting direction of the supporting part, increases the difficulty of accidental pull-out, and improves wearing safety.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By passing the support part of the connector through the insertion port and inserting it into the insertion cavity of the nose pad body, the connector is made of rigid material and the nose pad body is made of soft material, eliminating the need for bolts and special tools, making the nose pad easier to install and remove.

[0027] 2. The protrusions can shield the fixing part of the connector and reduce the risk of direct contact between the connector and the wearer's nose bridge. Combined with the cushioning effect of the soft nose pad body, it significantly reduces the local cold conduction effect and improves wearing comfort.

[0028] 3. Two opposing support parts provide additional support for the nose pad body, reducing the possibility of the nose pad body being accidentally pulled out in this direction of extension, allowing the nose pad body to be firmly installed on the frame, ensuring that the nose pad body is installed stably and reliably.

[0029] 4. The outer wall of the limiting part fits against the inner wall of the insertion port to limit the movement. When removing the nose pad body, you need to first move the mounting protrusion to disengage from the limiting part, and then pull it out along the direction of the support part. This reduces the possibility of the nose pad body being accidentally pulled out along the direction of the support part. Attached image description:

[0036] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0037] Example 1

[0038] As attached Figure 1 and attached Figure 2As shown, a nose pad that is easy to assemble and disassemble includes a nose pad body 2 for mounting on a frame 1. The nose pad body 2 is made of a soft material, such as silicone or rubber, preferably silicone. The nose pad body 2 includes a mounting protrusion 21 and two nose pads 22. The two nose pads 22 extend in opposite directions and are fixedly connected to both ends of the mounting protrusion 21. The nose pads 22 contact the bridge of the wearer's nose. The shape of the nose pads 22 is an arc shape that conforms to the contour of the bridge of the nose, and the surface is smooth to improve wearing comfort. The nose pads 22 are connected to the mounting protrusion 21 by integral molding. The mounting protrusion 21 has two adjacent insertion ports 211. The opening cross-section of the insertion ports 211 is rectangular, and the nose pads 22 have a insertion cavity 221 that communicates with the insertion ports 211. The nose pads 22 have a certain degree of elasticity due to the closed insertion cavity 221 inside.

[0039] An arched airbag portion 23 is connected to the end of the nose pad portion 22. The arched airbag portion 23 increases the cavity of the insertion cavity 221 between the airbag portion 23 and the nose pad portion 22, which can provide a certain elastic support when the nose pad body 2 is worn, further improving the comfort of wearing the nose pad body 2.

[0040] Example 2

[0041] As attached Figure 3 and attached Figure 4 As shown, a glasses frame includes a frame 1 and a nose pad body 2 disposed on the frame 1. The frame 1 has a fixing groove 11 and also includes a rigid connector 3. The connector 3 includes a fixing part 31, a limiting part 32 and a supporting part 33. The fixing part 31 has a threaded hole 311 and is fixed in the fixing groove 11 by the engagement of the bolt threaded hole 311, realizing the detachable connection of the fixing part 31 to the frame 1. The fixing part 31 is parallel to the mounting protrusion 21, and the mounting protrusion 21 can cover the part of the connector 3 with screw holes, which is both aesthetically pleasing and effectively eliminates direct contact between the connector 3 and the bridge of the nose, improving wearing comfort.

[0042] The fixing part 31 is parallel to the mounting protrusion 21, and the cross section of the fixing part 31 perpendicular to the mounting protrusion 21 is smaller than the cross section of the mounting protrusion 21 perpendicular to the fixing part 31. Thus, the mounting protrusion 21 on the nose pad body 2 can shield the fixing part 31 with screw holes on the connector 3, and reduce the risk of direct contact between the connector 3 and the wearer's nose bridge. Combined with the cushioning effect of the soft nose pad body 2, the local cold conduction effect is significantly reduced, and the wearing comfort is improved.

[0043] As attached Figure 4 and attached Figure 5As shown, there are two support parts 33, which extend in opposite directions. The two support parts 33 are respectively connected to the limiting part 32. The limiting part 32 is strip-shaped, and the other end of the limiting part 32 is connected to the fixing part 31. The fixing part 31, the limiting part 32 and the support part 33 are integrally formed. The ends of the two support parts 33 pass through the two insertion ports 211 and are inserted into the insertion cavity 221. The support part 33 can provide stable support for the nose pad body 2 and ensure that the nose pad body 2 is installed firmly.

[0044] The outer wall of the support part 33 fits and abuts against the inner wall of the insertion cavity 221. When the support part 33 is inserted into the insertion cavity 221, the friction between the support part 33 and the inner wall of the insertion cavity 221 is increased. The two fit together tightly, which can enhance the stability of the connection on the one hand, and prevent the support part 33 from shaking on the other hand, thus improving the stability of the wearer when wearing it.

[0045] The support part 33 includes a connecting section 331 and a support section 332. One end of the connecting section 331 is connected to the fixing part 31, and the other end of the connecting section 331 is connected to the support section 332. The cross section of the support section 332 perpendicular to its own extension direction is larger than the cross section of the connecting section 331 perpendicular to the extension direction of the support section 332. The cross section of the support section 332 perpendicular to its own extension direction is larger than the cross section of the connecting section 331 perpendicular to the extension direction of the support section 332, making the support section 332 more easily deformable than the connecting section 331. During disassembly and assembly, the support section 332 deforms first, reducing the pull-out resistance and improving the convenience of disassembly and assembly of the nose pad body 2. At the same time, the large cross section of the support section 332 disperses the pressure of the nose pad body 2, avoiding excessive local pressure that could lead to material fatigue, and improving the convenience and stability of disassembly and assembly of the nose pad body 2.

[0046] The guide slope 34 connecting the connecting section 331 and the support section 332 serves as a guide. Since the nose pad body 2 is made of soft material, after the support part 33 is inserted into the support leaf part 22, the nose pad body 2 will cover the outer wall of the support part 33. At this time, the guide slope 34 makes it easier to pull out the support part 33, reducing the possibility of the nose pad body 2 and the support part 33 getting stuck and blocking each other, and further improving the convenience and smoothness of nose pad assembly and disassembly.

[0047] The outer wall of the limiting part 32 fits against the inner wall of the insertion port 211, and the limiting part 32 and the support part 33 extend in different directions. When the end of the support part 33 passes through the insertion port 211 and is inserted into the insertion cavity 221, the insertion port 211 and the limiting part 32 cooperate to limit the insertion. When removing the nose pad body 2, it is necessary to first move the mounting protrusion 21 to disengage from the limiting part 32, and then pull it out along the direction of the support section 332. This reduces the possibility of the nose pad body 2 being accidentally pulled out along the direction of the support section 332.

[0048] The implementation principle of this second embodiment is as follows:

[0049] The fixing part 31 is pre-fixed to the frame 1 by a bolt passing through the threaded hole 311. When the wearer replaces the nose pad body 2 in the future, the wearer first moves the mounting protrusion 21 horizontally to disengage the mounting protrusion 21 from the limiting part 32, and then pulls out the nose pad body 2 along the direction extending from the end of the support part 33. The nose pad body 2 is made of soft material, and the nose pad body 2 will deform to a certain extent when pulled out.

[0050] The wearer then aligns the two insertion ports 211 on the nose pad body 2 that needs to be replaced with the two support parts 33 respectively. First, one support part 33 is passed through the insertion port 211 and inserted into the insertion cavity 221. Then, the other support part 33 is passed through the insertion port 211 and inserted into the insertion cavity 221. The soft material nose pad body 2 springs back and wraps around the support part 33. The entire replacement of the nose pad body 2 does not require the use of special tools to disassemble and assemble the nose pad body 2, making the disassembly and assembly of the nose pad body 2 more convenient.

[0051] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
