Eyewear is made of transparent materials, and there are general glasses with an adjusted refractive index, but there are also products such as sunglasses and goggles that protect the user's eyes from glare or ultraviolet rays by lowering the transmittance. Commonly used sunglasses are manufactured by adding colorants to transparent eyeglass materials or coating or depositing light-reflecting materials to reduce glare to users or protect their eyes from ultraviolet rays. In the case of eyewear, there is a frame to support the lens, temples connected to the frame to seat the eyewear on the user's ears, and a nose to support the eyewear on the bridge of the user's nose at the center of the eyewear that touches the user's nose. It is generally composed of a support (nose pad).

In the case of eyewear nose pads, the frame itself, which is made of a hard material such as plastic resin, may be configured to have a shape that protrudes in the direction of the user's nose. In this case, if the eyewear is worn for a long time, the bridge of the user's nose may be damaged. There were many cases where marks were left in the shape of the nose pad or users felt uncomfortable due to the hard material. To prevent this, a separate method of attaching a nose pad made of rubber or silicone to the frame of the eyewear was used, but there was a problem of the nose pad being undesirably easily separated from the frame or losing the nose pad.

Accordingly, there is a need for research on nose pads attached to eyewear that allow users to use the eyewear conveniently but also prevent the nose pad from being easily separated.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure 1 is a perspective view schematically showing eyewear according to an embodiment of the present invention, and Figure 2 is a perspective view schematically showing the frame portion where the nose pad is combined with the eyewear according to an embodiment of the present invention. It is done. In addition, Figure 3 shows a view showing the surface of the nose pad coupled to the eyewear according to an embodiment of the present invention, and Figure 4 shows the nose pad according to an embodiment of the present invention coupled to the frame of the eyewear. A drawing schematically showing the appearance is shown, and FIG. 5 shows a cross-sectional view taken along line A-A' in FIG. 4.

Referring to Figures 1 to 5, the nose pad for eyewear according to an embodiment of the present invention is a nose pad for eyewear that is coupled to the coupling rod 100 protruding from the nose pad frame 40 of the eyewear toward the user. Regarding (200), a coupling groove 230 formed to insert the coupling rod 100 inside, a first pad portion 210 disposed on the inner surface of the coupling groove 230, and the first pad It includes a second pad portion 220 surrounding the outside of the portion 210, and the hardness of the first pad portion 210 is higher than that of the second pad portion 220.

The nose pad frame 40 may be coupled to the lens 30 of the eyewear and placed at the bottom of the center, where it faces the user's nose. The nose pad frame 40 may be formed integrally with the frame coupled along the edge of the lens, but is not limited to this, and as shown in Figures 1 and 2, the nose pad may be provided separately only at the position where it touches the user's nose to minimize the frame. A support frame 40 may be formed. The nose pad 200 for eyewear is coupled to the nose pad frame 40 by inserting the coupling rod 100 protruding from the nose pad frame 40 toward the user into the inside. Meanwhile, the nose pad frame 40 may be made of a hard material such as plastic resin to firmly support the lens 30.

The coupling bar 100 protrudes from the nose pad frame 40 toward the user, and the protruding coupling bar 100 is coupled to and fixed to the nose pad 200. The coupling rods 100 may be formed in plural numbers and spaced apart from each other in the nose pad frame 40. That is, as shown in FIG. 2, the lower part of the center of the lens 30 includes a shape that is depressed upward at the area in contact with the bridge of the user's nose, and the nose pad frame 40 is coupled to the lens 30 at that area. It can be. At this time, the coupling rods 100 may be formed to be spaced apart from each other at positions corresponding to the left and right eyes of the lens 30, and may be coupled to ensure the stability of the coupling of the nose pad 200 at each of the left and right eye positions. A plurality of rods 100 may be formed. For example, the coupling rods 100 may be formed with two in the left direction and two in the right direction spaced apart from each other, so that the nose pad 200 can be more stably coupled to the coupling rod 100. .

The coupling groove 230 is formed as an empty space to insert the coupling rod 100 inside the nose pad 200. Therefore, the coupling rod 100 is inserted into the coupling groove 230 so that the nose pad 200 can be eventually coupled to the nose pad frame 40. Unlike the nose pad frame 40, which is made of a relatively hard material, the rubber A nose pad 200 made of a soft silicone material is present on the outside, and the soft nose pad 200 is in contact with the skin of the bridge of the user's nose, allowing the user to conveniently wear and use the eyewear. Meanwhile, the coupling groove 230 is defined by the second pad portion 220 and the first pad portion 210 coupled to the inside of the second pad portion 220, and the coupling groove 230 is formed by the first pad portion 230. It is formed to penetrate the center of the portion 210 and also penetrate the center of the second pad portion 220 surrounding it.

The first pad portion 210 is disposed on the inner surface of the coupling groove 230 and is surrounded by the second pad portion 220. That is, there is a region in the second pad portion 220 that is recessed inward to form the coupling groove 230, and the first pad portion 210 is coupled to some of these regions and eventually coupled to the coupling groove 230. When the rod 100 is coupled, the first pad portion 210 and the coupling rod 100 are in contact with each other, and the second pad portion 220 and the coupling rod 100 are in contact with each other at the innermost part. In other words, it can be understood that the first pad portion 210 is coupled to a portion of the surface of the coupling groove 230 formed by the second pad portion 220.

The second pad portion 220 surrounds the outside of the first pad portion 210 and is exposed to the outside. The second pad portion 220 is made of a soft material and is in direct contact with the bridge of the user's nose. The second pad portion 220 allows the eyewear to be supported on the bridge of the user's nose. In the case of the present invention, compared to the frame 20 or the nose pad frame 40 made of a hard material, the second pad portion 220 is made of a soft material and is coupled to the nose pad frame 40 to support the part that touches the bridge of the user's nose. By making it soft, users can feel comfortable using it and do not feel uncomfortable even if they wear the eyewear for a long time.

Meanwhile, the hardness of the first pad portion 210 is higher than that of the second pad portion 220. That is, in other words, the hardness of the first pad portion 210 may be greater than that of the second pad portion 220 (that is, it may have a higher hardness value). The second pad portion 220 By lowering the hardness, the part that directly touches the user can be made softer so that the user can feel comfortable using it, and by making the hardness of the first pad portion 210 relatively high, the nose pad is attached to the coupling rod 100. It can be firmly coupled and maintained. That is, the present invention adopts a structure in which a first pad part 210 and a second pad part 220 of different hardness are combined on the nose pad, and the first pad part 210 has a relatively high hardness, which ultimately improves the nose. While ensuring that the nose pad is firmly coupled to the support frame (40), the part that comes into direct contact with the user's skin (bridge of the nose) is made of a softer material, thereby maximizing the feeling of convenient use.

In the past, when a separate nose pad made of soft material was used by combining it with the nose pad frame for user convenience, there were cases where the nose pad could easily come off due to the excessively soft material, and to prevent this, high hardness was used. When combining the nose pads, the user felt uncomfortable due to the hard material. However, in the case of the present invention, the first pad part 210 with high hardness is applied to the part coupled to the nose pad frame 40, and the second pad part 220 with low hardness is applied to the part that comes into contact with the user's skin. Thus, it is possible to provide a nose pad that is convenient to use and can be firmly coupled to the nose pad frame 40.

Meanwhile, the first pad portion 210 and the second pad portion 220 may be made of a soft material such as rubber, and, for example, may be made of a component containing a silicone material. At this time, the thinner wrap hardness (shore A) of the first pad portion 210 is in the range of 60 to 80, and the thinner wrap hardness (shore A) of the second pad portion 220 is in the range of 20 to 40. It can be characterized, for example, the thinner wrap hardness (shore A) of the first pad portion 210 is in the range of 65 to 75, and the thinner wrap hardness (shore A) of the second pad portion 220 is in the range of 65 to 75. may be characterized as being in the range of 25 to 35. The user can feel convenience when wearing eyewear within the range of the thinner wrap hardness (shore A) of the second pad part 220, and the thinner wrap hardness (shore A) of the first pad part 210 After the nose pad 200 is coupled to the coupling rod 100 within the range, it can be prevented from being easily separated.

Meanwhile, to describe the coupling bar 100 in more detail, the coupling bar 100 includes a plurality of spaced apart support bars 110 protruding and extending from the nose pad frame 40 in the direction of the user's face, and the support bar. It may include a stopper 120 that is connected to 110 and has a thicker thickness than the support bar 110 at a position spaced apart from the nose pad frame 40. That is, the coupling rod 100 can form a stopper 120 whose end becomes thicker as it moves toward the user's face (nose bridge), and the thickness between the nose pad frame 40 and the stopper 120 is greater than that of the stopper 120. A thin support bar 110 can be formed. Accordingly, the nose pad 200 can be prevented from being easily separated after being coupled to the nose pad frame 40.

In addition, the first pad portion 210 may be characterized as being in contact with the support rod 110, and the stopper 120 is connected to the first pad portion 210 and the inside of the coupling groove 230. It may be characterized as being located between the second pad portions 220. Accordingly, when the nose pad 200 is coupled to the coupling bar 100, the first pad portion 210, which has relatively high hardness, passes through the stopper 120 and is coupled in contact with the support bar 110, and the stopper 120 By being located between the first pad portion 210 and the second pad portion 220, the nose pad 200 can be prevented from being easily separated from the coupling rod 100.

In addition, the stopper 120 may be characterized as being in contact with the boundary between the first pad portion 210 and the second pad portion 220, and more specifically, one end of the first pad portion 210 is The stopper 120 may be located at a point where the support rod 110 begins to become thicker. That is, the first pad portion 210 is located at the boundary between the support rod 110 and the stopper 120. In other words, the first pad portion 210 and the first pad portion 210 are located at the boundary between the support rod 110 and the stopper 120. The boundary of the second pad portion 220 may be divided. In this way, the first pad portion 210, which has relatively high hardness, is coupled to the thin support rod 110, and in the other area (the area of the thick stopper 120), the second pad portion (low hardness) has soft hardness (low hardness). As 220) is positioned, the nose pad 200 can be more firmly coupled to the coupling rod 100.

Meanwhile, in another embodiment, it is formed between the nose pad frame 40 and the support bar 110 and further includes a coupling bar step 130 thicker than the support bar 110, and the first pad portion ( The other end of 210) is located at the point where the coupling rod step 130 begins to thicken on the support rod 110, and the second pad portion 220 surrounds the coupling rod step 130 from the outside. It can be characterized as covering. Accordingly, the separated state of the first pad part 210 and the second pad part 220 is not exposed to the outside, and only a single surface of the second pad part 220 is exposed, resulting in an excellent design. By being positioned and coupled between the first pad portion 210, the coupling rod step portion 130, and the stopper 120, it is possible to prevent the nose pad from moving unintentionally by the user.
