In the present disclosure, "eyewear" refers to an instrument worn to cover the wearer's eyes. "Eyewear" includes eyeglasses for correcting refractive errors of the eye such as myopia, hyperopia or astigmatism, sunglasses for decorating the periphery of the eye, and goggles for protecting the eye. A "temple" refers to a pair of linear portions facing the wearer's temples and ears when the eyewear is worn, and is also referred to as a vine or arm.

FIG. 1 shows an exemplary eyewear 1 according to an embodiment. The eyewear 1 is a sports type eyewear, and may be, for example, golf eyewear, running eyewear, or road bike eyewear. The eyewear 1 includes a frame 10, a pair of lenses 20 fixed to the frame 10, and a cushion portion 50 that comes into contact with the wearer's body.

For example, the lens 20 is a plastic lens, but may be a glass lens. The lens 20 may have a spherical shape, or may have an aspherical shape such as a flat surface. The lens 20 may be a lens having a degree of correcting visual acuity, a contrast lens, or a polarized lens. Further, the lens 20 may be a lens having no dimming function and a polarizing function, or may be a non-power lens. As described above, various lenses can be used as the lens 20.

The frame 10 includes a front 11 extending along the direction D2, a pair of hinges 12 provided on both sides of the front 11, and a pair of temples 30 extending from each hinge 12 in the direction D1 intersecting the front 11. .. Between the hinge 12 and the temple 30, a joint 13 facing both ends of the direction D2 of the eyewear 1 is provided.

The front 11 is provided along the direction D2 in which the temples 30 are lined up, and has a pair of rims 11b surrounding the lens 20, a bridge 11c connecting the pair of rims 11b to each other, a pad 11d located below the bridge 11c, and a rim. It comprises a pair of twisted rods 11f that connect the 11b and the hinge 12 to each other. Yoroi 11f is also called Chi.

The rim 11b is, for example, a full rim that surrounds the entire circumference of the lens 20, but may be a half rim or an under rim, and the type of rim can be appropriately changed. As an example, a groove is formed on the inner peripheral surface of the rim 11b, and the lens 20 is fitted in the groove. The rim 11b may be omitted (or rimless eyeglasses such as two-point glasses may be used).

For example, the rim 11b has an upper edge portion 11g extending diagonally upward from the bridge 11c through the upper side of the lens 20 to the yarn 11f, and a first lower edge portion 11h extending diagonally downward from the bridge 11c along the lens 20. It has a second lower edge portion 11j extending diagonally downward along the lens 20 from 11f, and a lower end portion 11k connecting the first lower edge portion 11h and the second lower edge portion 11j to each other.

The bridge 11c is located in the center of direction D2 of the eyewear 1 and connects the pair of rims 11b to each other. The bridge 11c has, for example, a recess 11m recessed from the upper edge 11g of the rim 11b. The shape of the rim 11b and the shape of the bridge 11c are not limited to the above-mentioned examples and can be changed as appropriate.

The pad 11d is a nose pad that comes into contact with the wearer's nose and is made of, for example, silicon. The eyewear 1 includes a pair of pads 11d, and the pair of pads 11d is applied to the nose so as to sandwich the wearer's nose from both sides. As an example, the pad 11d includes an oval-shaped pad portion that comes into contact with the wearer's nose, and a fixing tool (also referred to as clings) that fixes the pad portion to the rim 11b. The shape, size and material of the pad 11d can be changed as appropriate.

FIG. 2 is a perspective view showing the temple 30 and the hinge 12. As shown in FIGS. 1 and 2, the temple 30 is rotatable along the direction D2 with the hinge 12 as a fulcrum. The hinge 12 is provided, for example, on the front 11 side of the temple 30 so that the temple 30 can be rotated toward the center side of the direction D2 of the eyewear 1.

The hinge 12 is, for example, a first portion 12c having a screw 12b connected to the twist 11f and extending in the vertical direction D3, a second portion 12d continuous with the temple 30, and a screw 12b fixed to the second portion 12d. And a plate-shaped portion 12f that is rotatable with respect to the first portion 12c.

As an example, each of the first portion 12c and the second portion 12d is rectangular parallelepiped and has a recess 12g into which the plate-shaped portion 12f is inserted. The plate-shaped portion 12f is inserted into the recess 12g so as not to protrude toward the center side in the direction D2 from the first portion 12c and the second portion 12d. The configuration of the hinge 12 is not limited to the above example and can be changed as appropriate.

The rim 11b, the bridge 11c, the twist 11f, the first portion 12c, the second portion 12d, and the temple 30 are made of, for example, resin. As an example, the rim 11b, the bridge 11c, the twist 11f, the first portion 12c, the second portion 12d and the temple 30 are made of TR90 material. In this case, the eyewear 1 can be made to be lightweight, highly flexible, and reduce discomfort when worn. However, the material of each part of the frame 10 is not limited to the above example and can be appropriately changed.

In this embodiment, the temple 30 is fixed to the hinge 12 of the frame 10. However, the temple 30 may be detachable from the eyewear 1 (frame 10), or may be a hingeless type that does not have a hinge 12 and is integrated with the front 11. The temple 30 extends from the abutment 13 in a rod shape along the direction D1, for example, even if the temple 30 is curved toward the center side of the direction D2 of the eyewear 1, that is, along the wearer's head toward the tip 30b. good.

The temple 30 has a tip portion 31 including the tip portion 30b and located on the opposite side of the abutment 13, a root portion 32 adjacent to the abutment 13, and an intermediate portion 33 connecting the tip portion 31 and the root portion 32 to each other. The root portion 32 indicates, for example, a portion extending from the hinge 12 (second portion 12d) along the direction D1. The intermediate portion 33 indicates, for example, a portion of the root portion 32 that gradually bends from the opposite side to the hinge 12 toward the center side of the direction D2 of the eyewear 1.

For example, the cushion portion 50 is fixed to the center side of the direction D2 of the eyewear 1 in the temple 30. The cushion portion 50 functions as, for example, a cushioning member that cushions the wearer's impact and a breathing member that enhances the breathability of the wearer's body. The cushion portion 50 extends linearly along the direction D1 from, for example, the second portion 12d of the hinge 12. The cushion portion 50 comes into contact with, for example, the temples or ears of the wearer of the eyewear 1.

The cushion portion 50 is fixed to the temple 30 along the temple 30, and for example, the cushion portion 50 at the tip portion 31 is softer than the cushion portion 50 at the root portion 32. The cushion portion 50 may be gradually or gradually softened from the root portion 32 toward the tip portion 31. Further, the cushion portion 50 may be hardened from the root portion 32 toward the intermediate portion 33 and softened from the intermediate portion 33 toward the tip portion 31.

FIG. 3 is a perspective view showing the cushion portion 50. FIG. 4 is a side view showing the cushion portion 50. As shown in FIGS. 3 and 4, the cushion portion 50 has a long shape and extends, for example, in a rod shape along the longitudinal direction X1. The cushion portion 50 has a certain width in the lateral direction X2 of the cushion portion 50. The longitudinal direction X1 of the cushion portion 50 coincides with, for example, the direction D1 which is the extending direction of the temple 30.

The cushion portion 50 includes a plurality of linear members 51 made of a flexible material, and a fixing portion 52 that supports the plurality of linear members 51 and is fixed to the temple 30. In the present disclosure, "flexibility" refers to a property that can be flexed (flexibly deformed) by contact with the body. "Flexible material" refers to a material that is flexible upon contact with the body and may include a flexible material, an elastic material or a soft material.

For example, the shape of each linear member 51 is cylindrical. However, the shape of each linear member 51 may be elliptical, oblong, or prismatic. The fixing portion 52 is, for example, flat. As an example, the cushion portion 50 is fixed to the temple 30 by adhering the fixing portion 52 to the temple 30 with an adhesive. However, the cushion portion 50 may be fixed to the temple 30 by means other than adhesion, such as fitting or screwing.

The cushion portion 50 has a three-dimensional network structure 55 formed by three-dimensionally intersecting a plurality of linear members 51. In the present disclosure, "intersection" refers to a state in which a plurality of linear members intersect. "Cross" refers to a state in which a plurality of linear members are joined to each other and extend in different directions (for example, radially) from the joining point of the joining, and a state in which the plurality of linear members are not joined to each other and from a specific direction. It includes both the states of being in contact with each other when viewed.

In the present disclosure, the "three-dimensional network structure" refers to a three-dimensional structure formed by a plurality of linear members extending in at least three different directions. The inside of the cushion portion 50 has a hollow structure in which a plurality of cavities defined by a plurality of linear members 51 are lined up. That is, the cushion portion 50 has a hollow structure in which a plurality of cavities are arranged side by side. Therefore, the cushion portion 50 makes it possible to secure high air permeability.

The material of the cushion portion 50 is, for example, polyurethane. In this case, since the cushion portion 50 can be made of a soft material, the impact absorption effect of the cushion portion 50 can be enhanced and the safety for the wearer can be enhanced. However, the material of the cushion portion 50 may be a resin material (for example, a rubber material) other than polyurethane, and can be appropriately changed.

In the three-dimensional network structure 55, for example, each of the plurality of linear members 51 extends in different directions from each other. The three-dimensional network structure 55 has a plurality of network portions 56 defined by a plurality of linear members 51. In the present disclosure, the "reticulated portion" refers to a reticulated portion exposed on the surface of the cushion portion (for example, the surface 57 described later) and a reticulated portion located inside the cushion portion (which forms a hollow structure of the cushion portion inside). Includes both. The plurality of mesh portions 56 are continuously formed along the longitudinal direction X1 of the cushion portion 50. The plurality of mesh portions 56 are arranged along the lateral direction X2 of the cushion portion 50. The plurality of mesh portions 56 may be arranged periodically along the longitudinal direction X1, for example.

The number of mesh portions 56 arranged along the longitudinal direction X1 may be, for example, 20 or more and 40 or less, 20 or more and 35 or less, or 20 or more and 30 or less, for example, 25 or 26. .. The number of mesh portions 56 arranged along the lateral direction X2 is, for example, 3 or more and 7 or less, and 4 or 5 as an example. However, the number of the mesh portions 56 can be appropriately changed depending on the shape of the temple 30 to which the cushion portion 50 is fixed (for example, the length or width of the temple 30) or the material characteristics (for example, hardness) of the linear member 51. Is.

For example, the mesh portion 56 has a polygonal shape. As an example, the net-like portion 56 may include a hexagonal-shaped net-like portion and a square-shaped net-like portion. As described above, the shape of the reticulated portion in a part of the cushion portion 50 and the shape of the reticulated portion in the remaining portion of the cushion portion 50 may be different from each other.

When the mesh portion 56 includes a hexagonal mesh portion, the cushion portion 50 has a three-dimensional network structure 55 having a honeycomb structure. The length L1 of each mesh portion 56 in the longitudinal direction X1 is longer than the length L2 of each mesh portion 56 in the lateral direction X2. The magnification of the length L1 with respect to the length L2 is, for example, 1.5 times or more and 7 times or less, may be 3 times or more and 6 times or less, and as an example, 4 times or more and 5 times or less. .. However, the relationship between the length L1 and the length L2 of the mesh portion 56 can be changed as appropriate.

The cushion portion 50 includes, for example, one end portion 53 fixed to the tip end portion 31 of the temple 30 and the other end portion 54 fixed to the root portion 32 of the temple 30. The one end 53 is softer than the other 54. As an example, the cushion portion 50 gradually becomes softer from the other end portion 54 toward the one end portion 53. For example, the thickness of the linear member 51 at the tip 31 of the temple 30 may be smaller than the thickness of the linear member 51 at the root 32 of the temple 30. That is, the thickness of the linear member 51 may be reduced from the other end portion 54 toward the one end portion 53. The height H of the upper end of the linear member 51 with respect to the fixed portion 52 (the length of the cushion portion 50 in the height direction X3) may be increased from the other end portion 54 toward the one end portion 53.

For example, the density of the three-dimensional network structure 55 at the tip portion 31 (one end portion 53) of the temple 30 is smaller than the density of the three-dimensional network structure 55 at the root portion 32 (the other end portion 54) of the temple 30. In this case, since the density of the three-dimensional network structure 55 decreases from the other end 54 toward the one end 53, the cushion portion 50 becomes softer from the other end 54 toward the one end 53. ..

The area of each mesh portion 56 (the area of the inner space of the network portion 56 defined by the plurality of linear members 51) may be widened from the other end portion 54 toward the one end portion 53. Further, the length L2 of the mesh portion 56 in the lateral direction X2 may become longer from the other end portion 54 toward the one end portion 53. By providing the linear member 51, the fixing portion 52, or the mesh portion 56 with the above-described configuration, a configuration in which the linear member 51, the fixing portion 52, or the net-like portion 56 gradually softens from the other end portion 54 toward the one end portion 53 is realized.

The cushion portion 50 may be gradually softened from the other end portion 54 toward the one end portion 53. The material of the linear member 51 at the other end 54 and the material of the linear member 51 at the one end 53 may be different from each other, and the hardness at the other end 54 and the hardness at the one end 53 may be different from each other. ..

The shape or area of the mesh portion 56 may differ depending on the portion of the cushion portion 50. On the other hand, at least one of the thickness of the linear member 51 and the height H of the upper end of the linear member 51 with respect to the fixing portion 52 may be constant. The length L1 of the reticulated portion 56 in the longitudinal direction X1 is constant, that is, the lengths L1 of the plurality of reticulated portions 56 may be the same as each other. Further, the density of the three-dimensional network structure 55 or the hardness of the cushion portion 50 may be constant along the longitudinal direction X1 and can be appropriately changed.

FIG. 5 is an enlarged perspective view of one end 53 of the cushion 50. FIG. 6 is a cross-sectional perspective view when the cushion portion 50 is cut along a plane extending in both the lateral direction X2 and the height direction X3. As shown in FIGS. 5 and 6, the cushion portion 50 has a surface 57 that comes into contact with the wearer's body (eg, temples or ears).

In the present disclosure, the "surface (of the cushion portion)" refers to a virtual surface constituting the outermost surface of the cushion portion. In the present embodiment, the shape of the surface 57 when the cushion portion 50 is cut along a plane extending in both the lateral direction X2 and the height direction X3 is the width of the fixed portion 52 from one end in the width direction of the fixed portion 52. It has an inverted U shape that extends to the other end in the direction.

The plurality of linear members 51 include a plurality of first linear members 58 extending along the surface 57 and a plurality of second linear members 59 extending in a direction intersecting the surface 57. The net-like portion 56 formed at the one end portion 53 may include, for example, at least one of a rectangular first-tip net-like portion 60 and a triangular second-tip net-like portion 61.

The mesh portion 56 formed on the surface 57 has, for example, a hexagonal shape. The plurality of first linear members 58 include, for example, a plurality of linear members 58b extending along the longitudinal direction X1 of the cushion portion 50, and a plurality of linear members 58c extending diagonally with respect to the longitudinal direction X1. Includes. The plurality of first linear members 58 may include linear members 58c extending perpendicularly to the longitudinal direction X1. The angle formed by the linear member 58b (longitudinal direction X1) and the linear member 58c is, for example, 20 ° or more and 90 ° or less, 25 ° or more and 60 ° or less, or 30 ° or more and 45 ° or less. It may be changed as appropriate.

A plurality of first intersections 62 where the linear member 58b and the linear member 58c intersect are formed on the surface 57. At the first intersection 62, for example, at least three linear members 51 (for example, one linear member 58b and two linear members 58c) intersect. The hexagonal mesh portion 56 is defined by, for example, two linear members 58b and four linear members 58c.

The second linear member 59 shows a linear member 51 that does not form the surface 57, and is located inside the cushion portion 50, for example, with respect to the surface 57. As an example, a part of the plurality of second linear members 59 extends inward from the first intersection 62 described above to the inside of the cushion portion 50, and the rest extends along the longitudinal direction X1. Inside the cushion portion 50, a plurality of second intersections 63 where a plurality of second linear members 59 intersect are formed. At the second intersection 63, for example, at least three second linear members 59 intersect.

The number of the first intersection 62 and the second intersection 63 (the number of branches of the linear member 51) described above may differ depending on the portion of the cushion portion 50. The cushion portion 50 becomes harder as the number of the first intersection 62 and the second intersection 63 (hereinafter, may be simply referred to as “intersection”) increases, and becomes softer as the number of intersections decreases. Therefore, in the cushion portion 50, the hardness of the cushion portion 50 can be adjusted by adjusting the number of intersecting portions where the plurality of linear members 51 intersect.

For example, the number of intersections of the cushion portion 50 (one end 53) at the tip 31 of the temple 30 may be less than the number of intersections of the cushion 50 (the other end 54) at the root 32 of the temple 30. .. In this case, a configuration is realized in which the cushion portion 50 becomes softer from the other end portion 54 toward the one end portion 53.

In a cross section in which the cushion portion 50 is cut along a surface extending in both the lateral direction X2 and the height direction X3, the plurality of first linear members 58 are arranged so as to surround the plurality of second linear members 59. There is. In the present embodiment, in the cross section, five first linear members 58 (linear members 58b) are arranged so as to surround the two second linear members 59.

The fixing portion 52 has, for example, a flat surface 52b on which a plurality of second linear members 59 extend, and protruding portions 52c formed at both ends of the fixing portion 52 in the width direction when viewed from the flat surface 52b. Each protruding portion 52c protrudes from the flat surface 52b in a curved surface shape (as an example, an arc shape).

The plurality of protrusions 52c are arranged, for example, along the longitudinal direction X1 of the cushion portion 50. Each protrusion 52c has a linear shape extending in the longitudinal direction X1. As an example, the first linear member 58 may extend from the end of each protrusion 52c in the longitudinal direction X1. Further, the fixing portion 52 may have a flat fixing surface 52d fixed to the temple 30 on the opposite side of the flat surface 52b.

The cross-sectional shape of the linear member 51 (each of the first linear member 58 and the second linear member 59) when the linear member 51 is cut along a plane orthogonal to the longitudinal direction is, for example, a circular shape. ing. However, the cross-sectional shape may be a square shape with rounded corners, an oval shape, an elliptical shape, or a polygonal shape. For example, the thickness T of the linear member 51 is 0.5 mm or more and 1.0 mm or less.

In the present disclosure, the "thickness of the linear member" indicates the width of the linear member, and is, for example, the average value of the widths of a plurality of linear members. When the cross-sectional shape when the linear member 51 is cut along a plane orthogonal to the longitudinal direction of the linear member 51 is circular, the thickness T of the linear member 51 is the diameter of the cross section of the linear member 51. Equivalent to. When the cross-sectional shape of the linear member when the linear member is cut along a plane orthogonal to the longitudinal direction of the linear member is square, the thickness of the linear member corresponds to one side of the cross section of the linear member. The lower limit of the thickness T of the linear member 51 may be 0.6 mm or 0.7 mm. The upper limit of the thickness T of the linear member 51 may be 0.9 mm, 0.8 mm or 0.7 mm.

Since the cushion portion 50 configured as described above has a three-dimensional network structure 55 in which a plurality of linear members 51 (first linear member 58 and second linear member 59) intersect three-dimensionally, for example. , Not manufactured by injection molding, but by a 3D printer. In this case, the three-dimensional net-like structure 55 of the cushion portion 50 can be easily modeled, and the cushion portion 50 according to the wearer can be easily manufactured in a short time. That is, it is also possible to easily perform custom-made.

Subsequently, the action and effect of the eyewear 1 and the temple 30 according to the present embodiment will be described in detail. As shown in FIG. 1, the eyewear 1 and the temple 30 include a cushion portion 50 that comes into contact with the wearer's body when worn. The cushion portion 50 has a three-dimensional network structure 55, and the three-dimensional network structure 55 is formed by three-dimensionally intersecting a plurality of linear members 51 made of a flexible material.

Therefore, a plurality of linear members 51 formed of the three-dimensional network structure 55 and made of a flexible material come into contact with the wearer's body. That is, in the eyewear 1 and the temple 30, since the plurality of flexible linear members 51 come into contact with the body, it is possible to prevent the wearer from getting stuffy and to make the wearer less likely to feel annoyed. Therefore, when a plurality of linear members 51 made of a flexible material come into contact with the body at the time of wearing, the fit and breathability can be improved.

As shown in FIG. 6, the cushion portion 50 has a surface 57 in contact with the body, and the plurality of linear members 51 include a plurality of first linear members 58 extending along the surface 57 and a surface thereof. A plurality of second linear members 59 extending in a direction intersecting 57 may be included. In this case, the plurality of flexible first linear members 58 extend along the surface 57 of the cushion portion 50, so that the plurality of flexible first linear members 58 come into contact with the body. Therefore, the cushioning property for the body can be enhanced.

Further, since the plurality of flexible second linear members 59 extend in the direction intersecting the surface 57 of the cushion portion 50, the strength of the cushion portion 50 when an external force acts on the surface 57, that is, the mounting. The contact strength with the person's body can be easily adjusted. Therefore, not only the surface shape of the cushion portion 50 when not mounted can be maintained by elasticity, but also the cushioning property of the cushion portion 50 when mounted can be ensured. As a result, the comfort of wearing the eyewear 1 can be improved and the fit can be improved.

As shown in FIGS. 3 and 4, the three-dimensional network structure 55 has a plurality of network portions 56 defined by a plurality of linear members 51, and each network portion 56 may have a polygonal shape. good. In this case, the three-dimensional network structure 55 can be easily manufactured. That is, when the three-dimensional network structure 55 is formed by the polygonal network portion 56, the number and arrangement of the network portions 56 can be easily designed.

Each net-like portion 56 may have a hexagonal shape. In this case, the number and arrangement of the mesh portions 56 can be designed more easily. That is, when each mesh portion 56 has a hexagonal shape, it is possible to design the arrangement of the mesh portions 56 having regularity. Therefore, the density and the like of the three-dimensional network structure 55 at the design stage and the contact strength of the cushion portion 50 can be calculated. Can be easily calculated.

The cushion portion 50 has a long shape, and the length L1 of each mesh portion 56 in the longitudinal direction X1 of the cushion portion 50 is longer than the length L2 of each mesh portion 56 in the lateral direction X2 of the cushion portion 50. May be good. In this case, since a plurality of reticulated portions 56 extending long along the longitudinal direction X1 of the cushion portion 50 are formed, the number of reticulated portions 56 can be increased. Therefore, it contributes to the improvement of the cushioning property and the design property of the cushion portion 50.

As shown in FIGS. 1 and 2, the cushion portion 50 is fixed to the temple 30 along the temple 30 of the eyewear 1, and the tip portion 31 of the temple 30 having a relatively wide contact area with the wearer. The cushion portion 50 (one end portion 53) in the above may be softer than the cushion portion 50 (the other end portion 54) in the root portion 32 of the temple 30, which has a relatively narrow contact area with the wearer. In this case, since the cushion portion 50 (one end portion 53) located at the tip portion 31 of the temple 30 is relatively soft, the cushioning property when the eyewear 1 is attached and the tip portion 31 of the temple 30 comes into contact with the body. And the fit can be further improved.

Further, since the cushion portion 50 (the other end portion 54) located at the root portion 32 of the temple 30 is relatively hard, the hinge 12 (second portion 12d) of the root portion 32 of the temple 30 and the cushion when an external force is applied are used. Since the generation of a step with the portion 50 can be suppressed, the pressure from the hinge 12 or the like on the body can be relieved. Therefore, the safety for the wearer can be enhanced.

As shown in FIG. 6, the thickness T of the linear member 51 may be 0.5 mm or more and 1.0 mm or less. By the way, when the thickness of the linear member is less than 0.5 mm, there is a concern that the three-dimensional net-like structure becomes too soft and the elasticity of the cushion portion decreases. Further, when the thickness of the linear member is thicker than 1.0 mm, there is a concern that the three-dimensional net-like structure becomes hard and the flexibility of the cushion portion decreases. On the other hand, when the thickness T of the linear member 51 is 0.5 mm or more and 1.0 mm or less, the elasticity and flexibility of the cushion portion 50 can be made appropriate, so that the fit to the wearer is improved. Contribute to.

The cross-sectional shape of the linear member 51 may be circular, elliptical or oval. In this case, since the rounded portion of the linear member 51 comes into contact with the wearer's body, the fit can be further improved.

The embodiments of the eyewear and temples according to the present disclosure have been described above. However, the present disclosure is not limited to the above-described embodiment, and may be modified or applied to other things without changing the gist described in each claim. That is, the shape, size, material, number, and arrangement of each part of the eyewear and the temple can be appropriately changed without departing from the above gist.

In the above-described embodiment, the eyewear 1 which is a sports type eyewear has been described. However, the eyewear may be eyewear other than sports type, sunglasses or goggles, and the type of eyewear can be changed as appropriate.

In the above-described embodiment, the cushion portion 50 provided with the hexagonal mesh portion has been described. However, the mode of the cushion portion is not limited to the example of the above-described embodiment and can be appropriately changed. For example, in the above-described embodiment, the cushion portion 50 in which the linear member 51 forms a plurality of net-like portions 56 has been described. The cushion portion may be one in which all or part of the plurality of reticulated portions 56 is covered with a film-like member. Examples of the film-like member include a breathable member having a mesh-like hole (for example, gauze) or a thin-film member made of an elastic material (for example, rubber). As described above, even if at least one of the plurality of mesh portions 56 is a cushion portion covered with a film-like member, the same effect as that of the cushion portion 50 can be obtained.

As shown in FIG. 7, for example, the cushion portion may be a cushion portion 70 in which a rectangular mesh portion 76 extending in the longitudinal direction X4 is formed. The material of the cushion portion 70 may be the same as the material of the cushion portion 50, for example.

The cushion portion 70 includes a plurality of linear members 71 extending in the longitudinal direction X4 of the cushion portion 70, a plurality of linear members 72 extending in the lateral direction X5 of the cushion portion 70, and the linear members 71 and the linear members 72. A linear member 73 extending from the intersection 74 to the surface 77 of the cushion 70 in a direction intersecting the surface 77 is provided.

The net-like portion 76 exhibits a rectangular shape defined by, for example, two linear members 71 and two linear members 72. Like the mesh portion 76, the shape of the mesh portion of the cushion portion can be changed as appropriate. The shape of the net-like portion may be a square shape with rounded corners, an oval shape, or an elliptical shape. Further, the size (area), the number, and the arrangement mode of the reticulated portion are not limited to the above-described embodiment and can be appropriately changed.

In the above-described embodiment, the cushion portion 50 fixed to the temple 30 has been described. However, the cushion portion may be detachable from the temple. For example, the cushion portion has a bag shape, and may have a structure in which a temple is inserted inside the bag-shaped cushion portion. In this case, the cushion material can be attached to the existing eyewear. Further, in eyewear in which the modern is formed at the tip of the temple, the cushion portion into which the modern is inserted may be used.

The cushion portion may be attached to a portion other than the temple 30. For example, the eyewear may include a cushion portion attached to a pad (nose pad). The pad to which the cushion portion is attached may be removable from the eyewear. For example, the cushion portion may be attached to a portion that comes into contact with the periphery of the eye of the wearer of the goggles, or a windshield portion around the eye in the eyewear for pollen cutting. In these cases as well, since the cushion portion comes into contact with the wearer's body (the nose, the portion around the eyes, etc.), the same effect as that of the above-described embodiment can be obtained.

In the above-described embodiment, the cushion portion 50 extending in a long shape from the root portion 32 to the tip portion 31 of the temple 30 has been described. However, the cushion portion may be provided only on the tip portion of the temple, for example. That is, the cushion portion may cover a part of the eyewear parts. Further, the shape of the cushion portion is not limited to the long shape, and can be appropriately changed according to the shape of the part to be attached and the like.
