[Example]
<Whole glasses>
FIG. 1 is a perspective view schematically showing an example of glasses 100 in the embodiment. The glasses 100 include a lens 110 and a frame. Glasses 100 is an example of eyewear. The frame includes, for example, a temple 130, a modern 132, a hood portion 160, a lens holding portion 170, and a prevention portion 180.

  The lens holding unit 170 supports the pair of lenses 110. The lens holding unit 170 includes a rim 122, a portion between the eyebrows (for example, a bridge) 124, and an armor 126.

  Further, the hood portion 160 is integrally formed with the temple 130 by a hinge 128 at both ends in the X direction. Depending on the type of glasses 100, there may be no bridge portion of the frame by using a single lens. In this case, the portion between the eyebrows of the single lens is the portion between the eyebrows.

  The hood portion 160 supports the lens holding portion 170 and is provided so as to be flexible independently of the lens holding portion 170. The hood portion 160 is flexible as the temple 130 expands or narrows according to the size of the face. Since the hood portion 160 is separate from the lens holding portion 170, the hood portion 160 is easily flexible according to the size of the face, and the adhesion between the hood portion 160 and the face can be improved. . Thereby, the hood part 160 can prevent a foreign material from entering the face through a gap between the hood part 160 and the face.

  In addition, the shape of the edge in the face direction of the hood part 160 should just be formed so that it may closely_contact | adhere to a person's standard face shape. Further, the hood portion 160 may be formed so as to be more flexible than the lens holding portion 170. Thereby, the hood part 160 becomes more flexible according to the size of the face, and the adhesiveness with the face increases.

  The frame also includes a prevention unit 180 that prevents foreign matter from entering the face direction from the gap between the lens holding unit 170 and the hood unit 160. The foreign matter is, for example, pollen or dust. When the hood unit 160 and the lens holding unit 170 are separated from each other, a gap is generated between the lens holding unit 170 and the hood unit 160, but the prevention unit 180 allows the foreign matter to enter the face direction from the gap. Can be prevented. A specific example of the prevention unit 180 will be described later.

  FIG. 2 is a plan view illustrating an example of the glasses 100 according to the embodiment. The glasses 100 shown in FIG. 2 are glasses viewed from above. As shown in FIG. 2, the hood portion 160 projects from the front side in the Y direction so as to be in close contact with the face in order to protect the eyes from pollen and dust. The hood portion 160 is flexible so that, for example, the curvature of the edge portion in the facial direction is increased or decreased.

  The lens holding part 170 is formed independently of the hood part 160. For example, the lens holding portion 170 and the hood portion 160 are connected by the eyebrow portion 124. In the present embodiment, the lens holding portion 170 and the hood portion 160 are connected at one point, but may be connected at two or more points such as two points in the vicinity of the end pieces 126 at both ends. Further, an elastic member such as a spring may be provided between the lens holding portion 170 and the hood portion 160 at a portion other than the connection point. In addition, the connection point between the lens holding unit 170 and the hood unit 160 may be fastened with, for example, a screw.

  The prevention unit 180 exists in the gap between the lens holding unit 170 and the hood unit 160. The prevention unit 180 uses a mechanism or material that prevents pollen, dust, or the like from entering the face direction.

  FIG. 3 is a diagram illustrating an example of an A-A ′ end surface of the glasses 100 according to the embodiment. The end surface shown in FIG. 3 has an end surface shape at A-A ′ shown in FIG. 2. In the example illustrated in FIG. 3, the lens holding unit 170 holds the lens 110. For example, the prevention unit 180 includes an extension part 177 that extends from the rim of the lens holding part 170 in the face direction and overlaps the edge part on the lens holding part 170 side of the hood part 160 in close contact with each other.

  The extending portion 177 may be formed of a member different from the lens holding portion 170. The hood portion 160 overlaps the extended portion 177 in the Z direction, and this overlap makes it difficult for foreign matter to enter from the gap between the lens holding portion 170 and the hood portion 160. Furthermore, the extending portion 177 may be provided to be inclined toward the hood portion 160 in the Z direction instead of being formed substantially parallel to the Y direction. Thereby, it is possible to further prevent foreign matter from entering from the gap between the lens holding portion 170 and the hood portion 160.

  In the example shown in FIG. 3, the hood portion 160 is provided outside the extending portion 177 when viewed from the center of the lens 110 in the Z direction, but the hood portion 160 is provided inside the extending portion 177. May be.

  FIG. 4 is an exploded perspective view of the glasses 100 in the embodiment. In the example shown in FIG. 4, the lens holding part 170, the hood part 160, and the temple 130 are formed separately. By forming the lens holding portion 170 and the hood portion 160 separately, the flexibility of the hood portion 160 is improved as compared with the case where the lens holding portion 170 and the hood portion 160 are integrally formed. The hood part 160 becomes easy to adhere to heads of various sizes due to increased flexibility.

  In the example shown in FIG. 4, the pair of nose pads 140 are provided on the hood portion 160. In addition, the hood portion 160 has a concave portion 165 in the portion between the eyebrows. The concave portion 165 is fitted to the convex portion of the lens holding portion 170 shown in FIG.

Next, the lens holding part 170 will be described. FIG. 5 is a rear view of the lens holding portion 170 in the embodiment. In the example shown in FIG. 5, the lens holding part 170 has a convex part 175 and an extending part 177.

  The convex portion 175 is fitted into the concave portion 165 shown in FIG. The convex portion 175 may have a screw hole 176. The screw hole 176 is not limited to one and may be plural. The lens holding part 170 and the hood part 160 may be fastened using a screw hole 176. In addition, when the lens holding | maintenance part 170 and the food | hood part 160 are fastened using a screw, the convex part 175 and the recessed part 165 are not necessarily a required structure.

  The extending portion 177 shown in FIG. 5 is formed so as to surround a portion other than the nose portion of the rim, for example. The extending portion 177 is a member that extends in the face direction from the rim side.

  FIG. 6 is a perspective view of the lens holding portion 170 in the embodiment. In the example shown in FIG. 6, a convex portion 175 is provided in the face direction of the inter-brow portion 124 of the lens holding portion 170. As described above, the convex portion 175 is fitted into the concave portion 165 of the hood portion 170.

  In the example shown in FIG. 6, as described above, the extending portion 177 is provided in the face direction from the rim of the lens holding portion 170. As shown in FIG. 6, the extending length of the extending portion 177 increases from the center to the outer side of the rim of the lens holding portion 170 in accordance with the standard face shape.

  6 is an example in which the lens holding unit 170 and the hood unit 160 are connected to each other at the eyebrow portion 124. On the other hand, when the lens holding portion 170 is connected to the hood portion 160 at both ends, the extending length of the extending portion 177 may be shortened from the center of the rim of the lens holding portion 170 to the outside.

<Food part>
Next, the hood part 160 will be described. FIG. 7 is a perspective view of the hood portion 160 in the embodiment. As shown in FIG. 7, the hood portion 160 has a pair of nose pads 140 in the nose portion, and a recess 165 in the interbrow portion.

  By fitting the concave portion 165 into the convex portion 175 of the lens holding portion 170, the lens holding portion 170 and the hood portion 160 are positioned and connected.

  The hood portion 160 is formed so that pollen, dust and the like do not enter the eye portion. For example, the hood portion 160 has a portion extending in the face direction. The length of the hood portion 160 extending from the center to the outside of the hood portion 160 is formed to be longer in the face direction.

  The thickness of the hood portion 160 may be formed so that the central portion is thinner than the outer portion. Thereby, the flexibility of the hood part 160 can be improved, and the edge part of the hood part 160 is easily adhered to the face. This is an effective means for increasing flexibility when the entire hood portion 160 is formed of the same material, for example.

<Flexibility of the hood portion 160>
Next, the flexibility of the hood part 160 will be described. FIG. 8 is a plan view showing a state in which the glasses 100 according to the embodiment are worn by a user having an ideal head size assumed in design.

  As shown in FIG. 8, there is a play portion (gap) between the hood portion 160 and the lens holding portion 170 in consideration of the bending of the hood portion 160. A prevention portion 180 (for example, an extending portion 177) for preventing foreign matter from entering the face direction from the gap is provided in the gap portion.

  Hereinafter, the prevention unit 180 will be described as the extended portion 177. The extending portion 177 is extended on the rim of the lens holding portion 170. The extended portion 177 may be formed of the same material as the rim, or may be formed of a different material. For example, the extended portion 177 may be formed of a photocatalyst or the like that adsorbs pollen or dust.

  FIG. 9 is a plan view showing a state in which the glasses 100 in the embodiment are worn by a user who is larger than the ideal head size assumed in design. As shown in FIG. 9, the hood part 160 is bent so that the curvature of the edge part in the face direction is larger than that of the hood part 160 shown in FIG. The hood unit 160 can easily adhere to the user's face using this flexibility. Further, since the lens holding portion 170 is formed independently of the hood portion 160, it is not affected by the bending of the hood portion 160.

  When the hood portion 160 is bent, the size of the gap with the lens holding portion 170 changes. However, the extending portion 177 is formed in a size that takes into account the variation in the size of the gap.

  As described above, according to the embodiment, by forming the lens holding portion 170 and the hood portion 160 independently, the hood portion 160 can be easily bent, and the edge of the hood portion 160 in the face direction can be easily adhered to the face. Furthermore, by providing the prevention unit 180 as described above between the hood unit 160 and the lens holding unit 170, even if the gap fluctuates due to the deflection of the hood unit 160, it is possible to appropriately prevent the entry of foreign matter. .

Even if the hood portion 160 </ b> A is bent, a part of the convex portion continues to be inserted into the concave portion.

  Thereby, even if the hood portion 160A is bent, the prevention portion 180A prevents foreign matter from entering from the gap between the lens holding portion 170A and the hood portion 180A. The prevention unit 180A is not limited to the shape shown in FIG. 12 as long as the concave portion of the lens holding portion 170A and the convex portion of the hood holding portion 160A can prevent entry of foreign matter.

  FIG. 13 is an end view showing an example of the prevention unit 180B in the modification. The prevention unit 180B shown in FIG. 13 shows the end surface of A-A ′ shown in FIG. 2 and has the same shape in the X direction. The prevention unit 180B is an extendable member that fills the gap between the lens holding unit 170A and the hood unit 160B. For example, the prevention unit 180A may be an elastic member such as rubber or a member that can expand and contract such as a bellows.

  As a result, even if the hood portion 160A is bent, the prevention portion 180B prevents foreign matter from entering from the gap between the lens holding portion 170A and the hood portion 180A.

  Moreover, the hood part 160 may be provided with an elastic part at the edge in the face direction. The elastic portion is an elastic member such as rubber. Thereby, an intrusion of a foreign object can be further prevented by the elastic part fitting to the face shape.
