Description

Eyewear and temple

Technical Field

The present invention relates to eyewear (eyewear) and temples.

Background

Japanese patent application laid-open No. 2017-26784 discloses eyeglasses comprising a front frame (front frame) for holding lenses, a pair of temples respectively attached to both ends of the front frame so as to be foldable, and a nose pad formed in the center of the front frame. The front frame and the pair of temples are made of resin such as urethane resin or silicone resin. Resins such as polyurethane resins and silicone resins are used as materials that are less likely to slip against the skin of a wearer of eyeglasses. The resin is in contact with the skin, and thus the deviation of the spectacles from the skin is suppressed.

Japanese patent application laid-open No. 10-161067 discloses glasses having a frame with a nose pad. In the eyeglasses, a pair of nose pads are disposed between the left and right lens holding frames in the eyeglass frame. The nose pad comprises a base material for the nose pad and a pad attached to the base material and in contact with the nose of a wearer. The blade is made of a soft porous material having water absorption, flexibility and elasticity. When the spectacles are worn, the support blade comes into contact with the nose of the wearer, thereby suppressing the displacement of the frame and reducing the uncomfortable feeling.

Japanese patent application laid-open No. 2019-66782 describes a cushion member for an eyeglass frame. The cushioning members are secured to the nose pad blade portion, the temple arms, and the front frame of the eyeglasses, respectively. The buffer piece is sheet-shaped and is made of silicon viscoelastic material. The cushion member is provided to protect the wearer and is brought into close contact with the wearer when the eyeglasses are worn.

Japanese patent application publication No. 2013-533512 discloses a spectacle frame for spectacles. The frame includes a pair of temples, a front portion connecting the pair of temples to each other, and a pair of nose pads projecting downward near the center of the front portion. Functional inserts having a plurality of holes through which vapor passes are formed in the spectacle spleen and the nose pad, respectively. If the user wears the eyeglasses having the functional insert, the vapor permeates the functional insert when sweat of the user turns into vapor. Thereby, the stay of sweat on the skin of the user is suppressed.

In Japanese unexamined patent publication Hei 2-81518, a nose pad blade of a spectacle frame is described. The eyeglass frame includes a pair of rims connected to each other via a connecting plate and having lenses attached thereto, a pair of posts positioned on both end sides of the pair of rims, respectively, and a pair of spleens rotatably connected to the respective posts via hinges. The spectacle frame is provided with a pair of nose pad supporting blades at the periphery of the spectacle frame and at the lower side of the connecting plate. The nose pad blades have blades formed in a mesh shape by crossing a plurality of thin lines in a lattice shape. By the contact of the leaf with the nose of the user, the air permeability in the nose portion is ensured.

Disclosure of Invention

Problems to be solved by the invention

In the above-described eyeglass frame, a resin material, a soft porous material, or a sheet-like cushion material is used for a portion that comes into contact with the body of the wearer, thereby achieving suppression of misalignment and protection of the wearer. In addition, in the above-described functional insert and the nasal splint, a plurality of holes are formed in a portion that contacts the body of the wearer, thereby preventing the staying of sweat and ensuring breathability.

However, when the material of the portion that contacts the body of the wearer is a cushion material or the like, it is assumed that the cushion material is still hot due to its close contact with the body, and improvement of the fit and the air permeability is desired. In addition, in the functional insert and the nasal splint in which a plurality of holes are formed in a portion that contacts the body of the wearer, the holes are two-dimensionally formed in a manner along a plane. However, in the case where the hole is formed two-dimensionally along a plane, since the hole has a planar structure, not only the strength against an external force is weak, but also it is difficult to ensure cushioning required for three-dimensional deformation of a portion in contact with the body of the wearer. Therefore, there is still room for improvement in cushioning properties and conformability.

The invention aims to provide an eyeglass and a temple which can improve the cushioning property, the bonding property and the air permeability.

Means for solving the problems

The present invention relates to an eyewear to be worn so as to cover the eyes of a wearer, the eyewear including a cushion section that contacts the body of the wearer, the cushion section having a three-dimensional mesh structure formed by three-dimensionally intersecting a plurality of linear members made of a flexible material.

The temple according to the present invention is a temple of eyewear to be worn so as to cover the eyes of a wearer, and includes a cushion section that comes into contact with the body of the wearer, the cushion section having a three-dimensional mesh structure formed by three-dimensionally intersecting a plurality of linear members made of a flexible material.

Effects of the invention

According to the present invention, cushioning properties, adhesion properties, and air permeability can be improved.

Detailed Description

Hereinafter, embodiments of eyewear and temples according to the present invention will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and overlapping description is appropriately omitted. In the drawings, parts may be drawn in a simplified or exaggerated manner, and the dimensions, angles, and the like are not limited to those shown in the drawings.

In the present invention, "eyewear" means an apparatus to be worn so as to cover the eyes of a wearer. The term "eyewear" includes glasses for correcting ametropia of eyes such as myopia, hyperopia, or astigmatism, sunglasses for decorating the periphery of eyes, goggles for protecting eyes, and the like. "temple" means a pair of linear portions that face the temple and ear of the wearer when the eyewear is worn, and is also referred to as the spleen or arm.

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

For example, the lens 20 is a plastic lens, but may be a glass lens. The lens 20 may have a spherical shape or an aspherical shape such as a planar shape. The lens 20 may be a lens with diopter for correcting vision, a contrast lens, or a polarized lens. The lens 20 may be a lens having no light control function and no polarization function, or may be a lens having no diopter. In this way, various lenses can be used as the lens 20.

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

The front frame 11 includes a pair of frame members 11b provided along the direction D2 in which the temples 30 are aligned and surrounding the lenses 20, a nose bridge 11c connecting the pair of frame members 11b to each other, a nose pad 11D positioned below the nose bridge 11c, and a pair of posts 11f connecting the frame members 11b and the hinges 12 to each other. The pile head 11f is also referred to as a locking block.

The frame 11b is, for example, a full-lens frame surrounding the entire circumference of the lens 20, but may be a half frame or an inverted frame (under rim), and the type of the frame may be changed as appropriate. As an example, a groove is formed in the inner peripheral surface of the frame 11b, and the lens 20 is fitted into the groove. The frame 11b (frameless glasses such as a two-point glasses) may be omitted).

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

The nose bridge 11c is located at the center of the eyeglasses 1 in the direction D2, and connects the pair of frame frames 11b to each other. The bridge 11c has a recess 11m recessed from the upper edge 11g of the frame 11b, for example. The shape of the frame 11b and the shape of the nose bridge 11c are not limited to the above examples and can be appropriately changed.

The nose pad 11d is a nose pad that contacts the nose of the wearer, and is made of, for example, silicone. The eyewear 1 includes a pair of nose pads 11d, and the pair of nose pads 11d contact the nose of the wearer so as to be sandwiched between the two sides of the nose. As an example, the nose pad 11d includes an oblong pad part that comes into contact with the nose of the wearer, and a fixing member (also referred to as a pad stem (pincs)) that fixes the pad part to the frame 11 b. The shape, size, and material of the nose pad 11d can be changed as appropriate.

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

The hinge 12 includes, for example, a first portion 12c connected to the pile head 11f and having a screw 12b extending in the vertical direction D3, a second portion 12D connected to the temple 30, and a plate-like portion 12f fixed to the second portion 12D and rotatable with respect to the screw 12b and the first portion 12 c.

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

The frame 11b, the bridge 11c, the stub 11f, the first portion 12c, the second portion 12d, and the temple 30 are made of resin, for example. As an example, the frame 11b, nose bridge 11c, post 11f, first portion 12c, second portion 12d, and temple 30 are constructed from TR90 stock. In this case, the eyewear 1 can be lightweight and highly flexible, and can reduce discomfort during wearing. 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 secured to the hinge 12 of the frame 10. However, the temple 30 may be detachable from the eyewear 1 (the frame 10), or may be a hingeless temple that is integrated with the front frame 11 without the hinge 12. The temples 30 extend from the seams 13 in the direction D1 to have a rod shape, and may be bent toward the center side of the direction D2 of the eyewear 1 toward the front end 30b, that is, along the head of the wearer, for example.

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

For example, the cushion portion 50 is fixed to the temple 30 on the center side in the direction D2 of the eyewear 1. The cushioning portion 50 functions as a cushioning member that cushions an impact on the wearer and a ventilation member that improves ventilation to the body of the wearer, for example. The cushioning portion 50 extends, for example, linearly from the second portion 12D of the hinge 12 along the direction D1. The cushioning portion 50 is, for example, in contact with temple or ear of the wearer of the eyewear 1.

The cushioning 50 is fixed to the temple 30 along the temple 30, for example, the cushioning 50 in the tip portion 31 is softer than the cushioning 50 in the base portion 32. The cushioning portion 50 may be gradually or stepwise softened as it goes from the root base portion 32 toward the tip end portion 31. Further, the cushioning portion 50 may be hardened from the base portion 32 toward the intermediate portion 33 and softened from the intermediate portion 33 toward the tip end portion 31.

Fig. 3 is a perspective view showing the buffer 50. Fig. 4 is a side view showing the buffer 50. As shown in fig. 3 and 4, the cushion portion 50 is elongated, and extends in a bar shape along the longitudinal direction X1, for example. The cushion portion 50 has a constant width in the short direction X2 of the cushion portion 50. The longitudinal direction X1 of the cushion 50 coincides with, for example, the direction D1 in which the temple 30 extends.

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

For example, each linear member 51 has a cylindrical shape. However, the shape of each linear member 51 may be an elliptic cylindrical shape, an elongated cylindrical shape, or a prismatic shape. The fixing portion 52 is flat, for example. For example, the cushion portion 50 is fixed to the temple 30 by bonding the fixing portion 52 to the temple 30 with an adhesive. However, the cushion 50 may be fixed to the temple 30 by means other than adhesion such as fitting or screw fixing.

The buffer 50 has a three-dimensional mesh structure 55 formed by three-dimensionally crossing a plurality of linear members 51. In the present invention, "cross" indicates a state where a plurality of linear members intersect. "crossing" includes both a state in which a plurality of linear members are joined to each other and extend in different directions (for example, radially) from the joined joint points, and a state in which a plurality of linear members intersect each other when viewed from a specific direction without being joined to each other.

In the present invention, the "three-dimensional network structure" means a three-dimensional structure formed by a plurality of linear members extending in at least three different directions from each other. The inside of the cushioning portion 50 has a hollow structure in which a plurality of hollow spaces defined by a plurality of linear members 51 are arranged. That is, the cushioning portion 50 has a hollow structure in which a plurality of cavities are arranged. Thus, the cushioning portion 50 can ensure high air permeability.

As an example, the material of the cushioning portion 50 is polyurethane. In this case, since the cushioning portion 50 can be made of a soft material, the impact absorption effect of the cushioning portion 50 can be improved, and safety for the wearer can be improved. However, the material of the cushioning portion 50 may be a resin material (e.g., a rubber material) other than urethane, and may be appropriately modified.

In the three-dimensional mesh structure 55, for example, the plurality of linear members 51 extend in different directions from each other. The three-dimensional mesh structure 55 has a plurality of mesh portions 56 defined by the plurality of linear members 51. In the present invention, the "net-like portion" includes both a net-like portion exposed on a surface (for example, a surface 57 described later) of the cushion portion and a net-like portion located inside the cushion portion (a hollow structure in which the cushion portion is formed). The plurality of mesh portions 56 are continuously formed along the longitudinal direction X1 of the cushion portion 50. The plurality of net portions 56 are arranged along the short side 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 the mesh portions 56 arranged along the longitudinal direction X1 is, for example, 20 or more and 40 or less, may be 20 or more and 35 or less, or 20 or more and 30 or less, and is 25 or 26 as an example. The number of the mesh portions 56 aligned in the short side direction X2 is, for example, 3 or more and 7 or less, and is 4 or 5 as an example. However, the number of the net portions 56 can be appropriately changed according to 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 characteristics (for example, the hardness) of the material of the linear member 51.

For example, the mesh portion 56 has a polygonal shape. As one example, the mesh portion 56 may include a hexagonal mesh portion, and a quadrangular mesh portion. In this way, the shape of the mesh portion in a part of the cushioning portion 50 and the shape of the mesh portion in the remaining part of the cushioning 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 mesh structure 55 having a honeycomb structure. The length L1 in the longitudinal direction X1 of each mesh portion 56 is longer than the length L2 in the transverse direction X2 of each mesh portion 56. 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, and may also 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 section 50 includes, for example, one end 53 fixed to the distal end 31 of the temple 30 and the other end 54 fixed to the base 32 of the temple 30. One end 53 is softer than the other end 54. For example, the cushioning portion 50 is gradually softened from the other end 54 toward the one end 53. For example, the thickness of the linear member 51 in the distal end portion 31 of the temple 30 may be thinner than the thickness of the linear member 51 in the base portion 32 of the temple 30. That is, the thickness of the linear member 51 may be tapered from the other end 54 toward the one end 53. The height H of the upper end of the linear member 51 with respect to the fixing portion 52 (the length of the cushioning portion 50 in the height direction X3) may be increased from the other end 54 toward the one end 53.

For example, the density of the three-dimensional mesh structure 55 at the distal end 31 (one end 53) of the temple 30 is lower than the density of the three-dimensional mesh structure 55 at the base 32 (the other end 54) of the temple 30. In this case, since the density of the three-dimensional mesh structure 55 decreases from the other end 54 toward the one end 53, the cushion portion 50 is configured to be softened from the other end 54 toward the one end 53.

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

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

The shape and area of the mesh portion 56 may be different depending on the position of the cushioning 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 mesh portion 56 in the longitudinal direction X1 may be constant, that is, the lengths L1 of the plurality of mesh portions 56 may be the same. Further, the density of the three-dimensional mesh structure 55 and the hardness of the cushion portion 50 may be constant along the longitudinal direction X1, and may be appropriately changed.

Fig. 5 is an enlarged perspective view of one end portion 53 of the cushioning portion 50. Fig. 6 is a cross-sectional perspective view of the cushion portion 50 cut along a plane extending in both the short-side direction X2 and the height direction X3. As shown in fig. 5 and 6, the cushioning portion 50 has a surface 57 that contacts the body (e.g., temple or ear) of the wearer.

In the present invention, "the surface (of the buffer portion)" means a virtual surface constituting the outermost surface of the buffer portion. In the present embodiment, the shape of the surface 57 after cutting the cushioning portion 50 along the plane extending in both the short direction X2 and the height direction X3 is an inverted U shape extending from one end in the width direction of the fixing portion 52 to the other end in the width direction of the fixing portion 52.

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 mesh portion 56 formed at the one end portion 53 may include at least one of a quadrangular first leading end mesh portion 60 and a triangular second leading end mesh portion 61, for example.

The mesh portion 56 formed on the surface 57 is, for example, hexagonal. The plurality of first linear members 58 include, for example, a plurality of linear members 58b extending along the longitudinal direction X1 of the cushioning portion 50, and a plurality of linear members 58c extending obliquely to the longitudinal direction X1. The plurality of first linear members 58 may include linear members 58c extending perpendicularly to the longitudinal direction X1. The angle between the linear member 58b (the longitudinal direction X1) and the linear member 58c may be, for example, 20 ° or more and 90 ° or less, or 25 ° or more and 60 ° or less, or 30 ° or more and 45 ° or less, and may be appropriately changed.

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

The second linear member 59 indicates the linear member 51 that does not form the surface 57, and is located, for example, inside the cushioning portion 50 from the surface 57. As an example, some of the plurality of second linear members 59 extend from the first intersection 62 toward the inside of the cushioning portion 50, and the remaining portions extend in the longitudinal direction X1. A plurality of second intersecting portions 63 where the plurality of second linear members 59 intersect are formed inside the cushioning portion 50. At least three second linear members 59 cross the second cross portion 63, for example.

The number of the first and second intersecting portions 62 and 63 (the number of branches of the linear member 51) may vary depending on the position of the cushioning portion 50. The buffer 50 is harder as the number of first intersections 62 and second intersections 63 (hereinafter, may be simply referred to as "intersections") is larger, and softer as the number of intersections is smaller. Therefore, in the cushioning portion 50, the hardness of the cushioning 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 cushioning 50 (one end 53) in the tip portion 31 of the temple 30 may be smaller than the number of intersections of the cushioning 50 (the other end 54) in the base portion 32 of the temple 30. In this case, the buffer portion 50 is configured to be softened from the other end 54 toward the one end 53.

In a cross section taken along the surface of the cushion portion 50 extending in both the short 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. In the present embodiment, five first linear members 58 (linear members 58b) are arranged so as to surround two second linear members 59 in the cross section.

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

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

The cross-sectional shape of the linear member 51 after cutting along a plane orthogonal to the longitudinal direction of the linear member 51 (each of the first linear member 58 and the second linear member 59) is, for example, a circular shape. However, the cross-sectional shape may also be a rounded quadrangle, an oval, an ellipse, or a polygon. For example, the thickness T of the linear member 51 is 0.5mm or more and 1.0mm or less.

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

The buffer 50 configured as described above has the three-dimensional mesh structure 55 in which the plurality of linear members 51 (the first linear member 58 and the second linear member 59) are three-dimensionally crossed, and therefore is manufactured by a 3D printer without injection molding, for example. In this case, the three-dimensional mesh structure 55 of the cushion unit 50 can be easily molded, and the cushion unit 50 corresponding to the wearer can be easily manufactured in a short time. That is, customization can be easily performed.

Next, the operation and effects of the eyewear 1 and the temples 30 according to the present embodiment will be described in detail. As shown in fig. 1, the eyewear 1 and the temples 30 include a cushion portion 50 that comes into contact with the body of the wearer when worn. The cushioning unit 50 has a three-dimensional mesh structure 55, and the three-dimensional mesh structure 55 is formed by three-dimensionally crossing a plurality of linear members 51 made of a flexible material.

Therefore, the body of the wearer comes into contact with the plurality of linear members 51 that form the three-dimensional mesh structure 55 and are made of a flexible material. That is, in the eyewear 1 and the temples 30, since the plurality of flexible linear members 51 are in contact with the body, stuffiness is less likely to occur, and the wearer is less likely to feel annoyed. Therefore, when the plurality of linear members 51 made of a flexible material is in contact with the body during wearing, the fit and air permeability can be improved.

As shown in fig. 6, the cushioning portion 50 has a body-contacting surface 57, and the plurality of linear members 51 may 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. In this case, since the plurality of flexible first linear members 58 extend along the surface 57 of the cushioning portion 50, the plurality of flexible first linear members 58 come into contact with the body, and thus the cushioning properties against the body can be improved.

Further, since the plurality of flexible second linear members 59 extend in the direction intersecting the surface 57 of the cushioning portion 50, the strength of the cushioning portion 50 when an external force acts on the surface 57, that is, the contact strength with the body of the wearer can be easily adjusted. Therefore, the surface shape of the cushion section 50 can be maintained by elasticity when not worn, and the cushioning properties of the cushion section 50 can be ensured when worn. As a result, the fitting property can be improved while the wearing comfort of the eyewear 1 is improved.

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

Each web 56 may be hexagonal in 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, since the arrangement design of the mesh portions 56 having regularity can be realized, the calculation of the density and the like of the three-dimensional mesh structure 55 and the calculation of the contact strength of the cushion portion 50 at the design stage can be easily performed.

The cushion portion 50 has an elongated shape, and the length L1 of each mesh portion 56 in the longitudinal direction X1 of the cushion portion 50 may be longer than the length L2 of each mesh portion 56 in the lateral direction X2 of the cushion portion 50. In this case, since the plurality of mesh portions 56 extending long in the longitudinal direction X1 of the cushioning portion 50 are formed, the number of mesh portions 56 can be increased. Therefore, the cushioning property and the design property of the cushioning portion 50 can be improved.

As shown in fig. 1 and 2, the cushion 50 is fixed to the temple 30 along the temple 30 of the eyeglass 1, and the cushion 50 (one end 53) in the distal end 31 of the temple 30 having a relatively large contact area with the wearer can be made softer than the cushion 50 (the other end 54) in the base 32 of the temple 30 having a relatively small contact area with the wearer. In this case, by making the cushion section 50 (one end 53) located at the distal end 31 of the temple 30 relatively soft, the cushion property and the fit property when the distal end 31 of the temple 30 is brought into contact with the body while wearing the eyewear 1 can be further improved.

Further, by making the buffer 50 (the other end 54) located at the base 32 of the temple 30 relatively hard, it is possible to suppress the occurrence of a step difference between the hinge 12 (the second portion 12d) or the like of the base 32 of the temple 30 and the buffer 50 when an external force is applied, and thus it is possible to alleviate stress from the hinge 12 or the like against the body. Thus, safety for the wearer can be improved.

As shown in fig. 6, the thickness T of the linear member 51 may be 0.5mm or more and 1.0mm or less. However, when the thickness of the linear member is less than 0.5mm, the three-dimensional net structure may be too flexible to reduce the elasticity of the cushion part. Further, when the thickness of the wire member is larger than 1.0mm, the three-dimensional mesh structure may be hardened to lower the flexibility of the cushioning portion. On the other hand, when the thickness T of the linear member 51 is 0.5mm or more and 1.0mm or less, the elasticity and flexibility of the cushioning portion 50 can be made appropriate, which contributes to improvement of the fit to the wearer.

The cross-sectional shape of the linear member 51 may be circular, elliptical, or oblong. In this case, the curved portion of the linear member 51 comes into contact with the body of the wearer, and thus the fit can be further improved.

The embodiments of the eyewear and temple according to the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and may be modified or applied to other embodiments without departing from the scope of the invention described in the claims. That is, the shapes, sizes, materials, numbers, and arrangement of the respective portions of the eyewear and the temple may be appropriately modified within the scope not departing from the gist of the invention.

In the above embodiment, the eyewear 1 as the sport type eyewear has been described. However, the eyewear may be other than the sport type eyewear, sunglasses, or goggles, and the type of eyewear may be changed as appropriate.

In the above embodiment, the cushioning portion 50 having the hexagonal mesh portion has been described. However, the form of the buffer portion is not limited to the example of the above embodiment and can be appropriately modified. For example, in the above embodiment, the cushioning portion 50 in which the plurality of mesh portions 56 are formed by the linear member 51 has been described. In the buffer portion, all or a part of the plurality of net portions 56 may be covered with a membrane member. Examples of the membrane-like member include a film-like member made of an air-permeable member (gauze, as an example) having mesh-like holes or an elastic material (rubber, as an example). In this way, even in the case of a cushioning portion in which at least one of the plurality of net portions 56 is covered with the film-like member, the same effect as that of the cushioning portion 50 can be obtained.

For example, as shown in fig. 7, the cushion portion may be a cushion portion 70 formed with a rectangular net portion 76 extending in the longitudinal direction X4. The material of the cushioning portion 70 may be the same as the material of the cushioning 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 a linear member 73 extending from an intersection 74 of the linear members 71 and the linear members 72 in a direction intersecting the surface 77 of the cushion portion 70.

The mesh portion 76 is, for example, a rectangular shape defined by two linear members 71 and two linear members 72. As with the mesh portion 76, the shape of the mesh portion of the cushion portion can be appropriately changed. The shape of the mesh portion may be a rounded quadrangle, an oval or an ellipse. The size (area), number, and arrangement of the mesh portions are not limited to those in the above-described embodiments, and can be modified as appropriate.

In the above embodiment, the cushion 50 fixed to the temple 30 is explained. However, the cushion portion may be detachable from the temple. For example, the cushion part may be formed in a bag shape, and have a structure in which temples are inserted into the bag-shaped cushion part. In this case, a cushion material can be attached to an existing eyewear. In addition, in the eyewear having the leg cover formed at the tip of the temple, the cushion portion into which the leg cover is inserted may be provided.

The cushion portion may be attached to a portion other than the temple 30. For example, the eyewear may have a cushion portion attached to a nose pad (nose pad). The nose pad to which the cushion portion is attached may be detachable from the eyewear. For example, the buffer portion may be attached to a portion of the goggle that comes into contact with the periphery of the eyes of the wearer, or a wind-proof portion around the eyes of an eyewear for blocking pollen. In these cases, the cushioning portion is also in contact with the body of the wearer (such as the nose and the portion around the eyes), and therefore the same effects as those of the above-described embodiment can be obtained.

In the above embodiment, the elongated cushion portion 50 extending from the base portion 32 to the distal end portion 31 of the temple 30 is explained. However, the buffer portion may be provided only at the tip end of the temple, for example. That is, the cushioning portion may cover a portion of the component of the eyewear. The shape of the buffer portion is not limited to a long shape, and can be appropriately changed according to the shape of the member to be mounted.
