Description

The present invention relates to a nose pad and eyewear provided with the nose pad.

When eyewear and a mask are used together, moist breath may leak from between the mask and the base of the nose, causing the lenses to fog up. Therefore, inventions have been proposed to hold down the mask so that there is no gap between the mask and the base of the nose (see, for example, Patent Documents 1 to 3).

Patent Literature 1 discloses an invention in which a plastic plate is attached to the gap between the box part that constitutes the clings (box leg) and the nose pad to hold down the mask. Patent Literature 2 discloses an invention in which a nose pad attached to a clings is wrapped in a nose pad extender for spectacles made of a soft material and extended downward. In Patent Document 3, an anti-fogging device for spectacles, which is made by bending a wire such as piano wire, is attached to a bridge in the center of the spectacles or a nose pad holding part (clings arm) that constitutes the clings to restrict the lifting of the mask. An invention to do is disclosed.

However, in the inventions disclosed in Patent Documents 1 and 2, the part that holds down the mask is fixed to the nose pad, and this nose pad swings with respect to the clings. The force that presses the mask using the contact force also escapes. On the other hand, as in the invention disclosed in Patent Document 3, when a spectacle fogging prevention device made by bending a wire made of a spring material is attached to a conspicuous bridge or clings arm in the center of the eyewear, the appearance of the eyewear when worn is large. It will change. Also, when attaching a bridge or clings arm by pinching it with the elasticity of the clip part or locking part (holding part), there is still play in the joint part of the eyewear and the anti-fogging device, so the force holding down the mask escapes. put away. Furthermore, if the anti-fogging device is only connected by a holding force that utilizes the elasticity of the material, the anti-fogging device may fall off.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a nose pad that can hold a mask stably and prevent lenses from becoming cloudy.

A nose pad according to an aspect of the present invention is a nose pad for eyewear, and includes a fixing portion attachable to a front frame holding a lens, a nose pad portion contacting a wearer's nose, and a wearer's mask. The three points of the fixing part, the nose pad part and the mask holding part are fixed to each other.

According to this aspect, since the fixed part, the nose pad part, and the mask holding part are fixed to each other, the mask is held down using the force of the nose pad coming into contact with the wearer's nose due to the weight of the eyewear or the like. Power is hard to escape. Since the fixed part is fixed to the front frame, there is no fear of the wearer falling off and injuring the wearer. To provide a nose pad capable of holding a mask stably and preventing the lens from becoming cloudy.

In the above aspect, the nose pads in the nose pad portion and the mask holding portion may be composed of a plastically deformable core material and an outer skin covering the core material.

According to this aspect, by plastically deforming the core material, it is possible to independently adjust the shapes of the nose pad portion and the mask holding portion according to the shape of the wearer's nose and the shape and wearing position of the mask. . In this case, it is sufficient that at least the wearer's nose and the portion that contacts the mask are covered with the outer skin. may

In the above aspect, in the nose pad portion, the core material may be formed in a ring shape having a through hole, and the through hole may be filled with a material that forms the outer skin.

According to this aspect, since the core material and the outer skin are firmly fixed in the through hole, the outer skin easily follows the deformation of the core material. In addition, especially when the material of the outer skin is soft, the shape of the outer skin can be maintained by the ring shape. When the outer skin is made of a translucent material, the inner side of the ring can be seen through, so that a clearer and lighter impression can be given than when the core material is not ring-shaped. As a result, the appearance is excellent.

In the above aspect, the core material may be plate-shaped.

According to this aspect, the cross section of the core material becomes flat. The skin easily follows the deformation of the core material compared to the case where the cross section of the core material is circular.

The above aspect further includes a second curved portion provided between the nose pad portion and the mask holding portion, and the core material is formed with a bent portion having a smaller cross-sectional area than the adjacent portion at the second curved portion. may be

According to this aspect, since the core material has a bent portion formed with a notch or a constriction to facilitate bending, the nose pad can be bent as intended by the designer who designed the bent portion in the second bending portion. can. In addition, even women and children with weak strength can easily adjust the shape of the nose pads.

In the above aspect, the eyewear may be configured to be replaceable by removing the nose pad from the front frame.

According to this aspect, the nose pad of the present invention can be removed and replaced with a normal nose pad, or the normal nose pad can be removed and replaced with the nose pad of the present invention. Therefore, it is economical because there is no need to replace the entire eyewear even in seasons when masks are not needed.

ADVANTAGE OF THE INVENTION According to this invention, a mask can be stably suppressed and the nose pad which a lens does not become cloudy can be provided.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that, in each figure, the same reference numerals have the same or similar configurations. The present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing an example of eyewear 1 having a nose pad 10 according to one embodiment of the present invention.

As shown in FIG. 1, the eyewear 1 is generally bilaterally symmetrical and includes a pair of left and right lenses 2 facing the wearer's eyes, a front frame 3 holding the lenses 2, and abutting on the wearer's ears. It includes a pair of left and right temples 4, a hinge 5 that rotatably connects the front frame 3 and the temples 4, a nose pad 10 that contacts the wearer's nose, and the like.

The nose pad 10 is fixed to the bridge 6 located in the central portion of the front frame 3 with fastening screws or the like. The nose pad 10 of this embodiment can be replaced with a new nose pad 10 by loosening the fastening screw. Other configurations 2 to 6 except for the nose pad 10 may be used from the existing eyewear 1. In that case, the fastening screw may be loosened to remove the normal nose pad and replace it with the nose pad 10 of the present embodiment.

2 is an enlarged perspective view of the nose pad 10 shown in FIG. 1, and FIG. 3 is a perspective view of the nose pad 10 shown in FIG. 2 viewed from the opposite side. As shown in FIGS. 2 and 3, the left portion 10L and the right portion 10R of the nose pad 10 are generally symmetrical.

Each of the left portion 10L and the right portion 10R includes a fixing portion 11 that can be fixed to the bridge 6 of the front frame 3, and a nose pad portion 13 and a mask holding portion 15 extending from the fixing portion. The nose pads 10 are arranged so that, when the eyewear 1 to which the nose pads 10 are attached is worn, the nose pads 13 are in contact with the wearer's nose and the mask holders 15 are in contact with the wearer's mask. It is configured. In the illustrated example, the left portion 10L and the right portion 10R are integrally formed and share a single fixing portion 11. As shown in FIG. Alternatively, the left portion 10L and the right portion 10R may be separated from each other, each provided with a fixing portion 11, and attached to the front frame 3 separately.

As shown in FIGS. 2 and 3 , the fixed portion 11 and the nose pad portion 13 are fixed to each other by the first curved portion 12 . The nose pad portion 13 and the mask pressing portion 15 are fixed to each other by the second curved portion 14 . Therefore, the fixing part 11, the nose pad part 13 and the mask holding part 15 are fixed to each other.

Each of the left portion 10L and the right portion 10R of the nose pad 10 extends from the fixing portion 11 to the mask holding portion 15 while gently curving in an S shape. A bending portion may be formed in the core material 20 to be described later so that the nose pad 10 can be easily bent at the first and second bending portions 12 and 14 . The bends are described in more detail below with reference to FIG.

In the following description, the fixed portion 11 side viewed from the mask holding portion 15 may be referred to as the base end side of the nose pad 10 , and the left and right mask holding portion 15 sides viewed from the fixed portion 11 may be referred to as the distal end side of the nose pad 10 . be. The mask holding portion 15 is a portion (tip portion) including the tip of the nose pad 10 and its vicinity.

The structure of the nose pad 10 is composed of a core material 20, an outer skin 30 covering the core material 20, and the like. At the fixing portion 11 , the core material 20 is exposed from the outer skin 30 . The core material 20 is covered with the outer skin 30 at other parts, that is, the first bending portion 12 , the nose pad portion 13 , the second bending portion 14 and the mask pressing portion 15 .

In this embodiment, the core material 20 is made of a plastically deformable metal material. The outer skin 30 is made of a flexible resin material. The resin material forming the outer cover 30 may be soft silicone resin, rubber resin, or the like, or slightly hard ethylene acid copolymer resin, or the like. It can be appropriately selected from known resin materials used for nose pads. The core material 20 and the outer skin 30 may be made of resin materials having different physical properties by using two-color molding, insert molding, or the like.

The core member 20 includes a connection portion 21, a branch portion 22, a top portion 23, a junction portion 24, parallel portions 25A and 25B, an extension portion 26, and the like. The core material 20 forming the left portion 10L and the core material 20 forming the right portion 10R of the nose pad 10 are connected to each other at a connecting portion 21 in the center of the core material 20. As shown in FIG. Specifically, the left end of the connecting portion 21 is connected to the branch portion 22 in the left portion 10L, and the right end of the connecting portion 21 is connected to the branch portion 22 in the right portion 10R. At least a portion of the connecting portion 21 protrudes outside the outer skin 30 to constitute the fixing portion 11 described above. Note that the fixed portion 11 may be covered with the outer skin 30 without protruding from the outer skin 30 .

As shown in FIGS. 2 and 3, in each of the left portion 10L and the right portion 10R of the nose pad 10, the core material 20 branches at a branch portion 22 to form two pieces, and then merges at a junction portion 24. It becomes one piece again and extends toward the mask holding portion 15 . In the illustrated example, the extending portion 26 of the core member 20 extends to the front of the mask pressing portion 15 at the tip of the nose pad 10 . If the tip of the extension part 26 is covered with the outer skin 30 , the extension part 26 may enter the mask holding part 15 and reach very close to the tip of the nose pad 10 .

Parallel portions (25A, 25B) in which the core material 20 is divided into two are formed between the branch portion 22 and the merging portion 24. As shown in FIG. In the nose pad portion 13, the parallel portions (25A, 25B) are formed in a ring shape having through holes. In the illustrated example, the core material 20 is formed in a substantially triangular ring shape having three corners (a branch portion 22, a top portion 23 and a confluence portion 24). The through hole inside the ring is filled with a resin material that forms the outer skin 30 .

FIG. 4 is a plan view showing the developed nose pad 10 shown in FIG. In the illustrated example, the core material 20 is formed by cutting out a sheet metal sheet by laser processing. The core material may be formed by punching out a sheet metal sheet by press working, may be formed by thinly extending a wire rod by press working, or may be formed into a plate shape using a 3D printer. . The cross section of the core material 20 is formed flat. As shown in FIG. 4, in each of the left portion 10L and the right portion 10R of the nose pad 10, the branch portion 22, the confluence portion 24, the parallel portion 25A, and the extension portion 26 of the core material 20 are arranged linearly. I'm in.

Specifically, the extension portion 26 is formed substantially parallel to the line segment connecting the branch portion 22 and the confluence portion 24 . One of the parallel portions 25A extends along a line segment connecting the branch portion 22 and the confluence portion 24. As shown in FIG. The other 25B is via the top 23 . The other parallel portion 25B is formed so as to move away from the parallel portion 25A as it goes from the branch portion 22 to the top portion 23 and to approach the parallel portion 25A as it goes from the top portion 23 to the confluence portion 24 .

The core member 20 is formed with a bent portion having a smaller cross-sectional area than the adjacent portion at the second curved portion. The bent portion may be a notch or constriction that makes the width of the sheet metal smaller than the adjacent portions, as indicated by reference numeral 27A in FIG. As indicated by reference numeral 27B in FIG. 4, piercing may be used to form a hole in the bent portion. As indicated by reference numeral 27C in FIG. 4, the recess may be processed so that the plate thickness is reduced instead of the width of the plate. The bent portion may be softened by annealing or the like.

According to the nose pad 10 according to the embodiment of the present invention configured as described above, there is no moving part such as clings between the front frame 3 of the eyewear 1 and the mask holding part 15 for holding the mask. , the force that presses the mask using the weight of the eyewear 1 is difficult to escape. It is possible to stably hold the mask and to provide a nose pad that prevents the lens 2 from becoming cloudy.

The core member 20 is a flat sheet metal, and two branched parallel portions (25A, 25B) are formed between the branch portion 22 and the confluence portion 24. As shown in FIG. The through hole between one side 25A and the other side 25B of the parallel portions is filled with a resin material forming the outer skin 30, and the core material 20 and the outer skin 30 are firmly fixed. Since the outer skin 30 easily follows the deformation of the core material 20, the nose pad 10 can be bent into a shape desired by the wearer. Also, since it is a flat sheet metal, the nose pad can be twisted, for example, on an axis passing through the proximal end and the distal end.

The embodiments described above are for facilitating understanding of the present invention, and are not intended to limit and interpret the present invention. Each element included in the embodiment and its arrangement, materials, conditions, shape, size, etc. are not limited to those illustrated and can be changed as appropriate. Also, it is possible to partially replace or combine the configurations shown in different embodiments.

For example, each of the left portion 10L and the right portion 10R of the nose pad 10 may have a C shape in which a portion of the ring-shaped portion is not connected. When the outer cover 30 is made of a soft material, forming the ring in a C shape can be expected to have effects such as gentle contact with the skin. Alternatively, in each of the left portion 10L and the right portion 10R of the nose pad 10, the ring-shaped portions (parallel portions 25A and 25B) formed from the core 20 may be omitted, or the core 20 may be provided with a plurality of rings. A shaped portion may be formed. For example, the core member 20 may be made of a substantially triangular flat sheet metal without through holes between the parallel portions 25A and 25B. Further, for example, the core material 20 is formed so that the extending portion 26 becomes wider toward the distal end side of the nose pad 10, and the proximal end side of the extending portion 26 is configured to be easier to bend than the distal end side. good too. In this case, the starting point of the extending portion 26 and its vicinity are the bending portions. In this case, since the surface area on the tip side of the mask pressing portion is widened, the surface for pressing the mask is widened, and the mask can be pressed more reliably.
