Background Art

[0002] Patent Document 1 describes a frame having a front, a yoke portion, and temples. The temples are attached to the yoke portion by hinges. The hinges are so-called spring hinges that include springs for holding the temples, and allow the temples to open at a right angle or more. Patent Document 1 describes a structure in which the hinge rotates about a single axis, and a structure in which the hinge has two axes. In the structure in which the hinge has two axes, the hinge rotates about two mutually perpendicular axes.

[0003] Patent Document 2 describes a hinge system for an eyeglass frame. This hinge system has a pivot point between a first rigid element and a second rigid element. The ends of each rigid element have bearing surfaces that face each other. This hinge system is a so-called spring hinge provided with elastic means for maintaining the contact of the bearings. The hinge system includes two pivoting portions having a concave area that is a curved surface. The two pivoting portions are fitted to each other through the connection of the concave areas and can pivot relative to each other like the links of a chain.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In eyewear equipped with the hinge described above, the temples can be bent in various directions relative to the front via the hinge. However, in Patent Document 1, when the temples are bent in various directions relative to the front, the front member (front side element 8) and base member (base 15) constituting the hinge are bent while in line or point contact with their respective contact surfaces. Similarly, in Patent Document 2, the first rigid element and the second rigid element are bent while in line contact. As a result, the bending motion of the temples relative to the front may be unstable, for example, by wobbling from side to side when bending in the vertical direction.

[0006] The present disclosure aims to provide eyewear and connecting members that allow for stable bending of the temples relative to the front, even while using spring hinges. [Means for solving the problem]

[0007] The eyewear according to this disclosure comprises (1) a frame having a front part including an endpiece and temples, and includes a connecting member for connecting the endpiece and the temples to each other. The connecting member comprises a first connecting portion connected to one of the temples and the endpiece, and a second connecting portion connected to the other of the temples and the endpiece. The first connecting portion has a first mounting portion attached to one of the temples and the endpiece, and a first hooking portion exposed from the first mounting portion. The second connecting portion has a second mounting portion attached to the other of the temples and the endpiece, and a second hooking portion exposed from the second mounting portion and hooking onto the first hooking portion. At least one of the first mounting portion and the second mounting portion is movable by an elastic body with respect to the portion in which the first hooking portion is hooked onto the second hooking portion. The first mounting portion has a first end that contacts the second mounting portion. The second mounting portion has a second end that contacts the first end. The first end has an arc-shaped portion that protrudes toward the second end. The second end has a recess into which the arc-shaped portion fits when the first connecting portion is bent toward the second connecting portion.

[0008] In this eyewear, the connecting member comprises a first connecting part having a first mounting part and a first hook part attached to one of the temple and the endpiece, and a second connecting part having a second mounting part and a second hook part attached to the other of the temple and the endpiece. At least one of the first mounting part and the second mounting part is movable by an elastic body relative to the portion in which the first hook part is hooked onto the second hook part. The first end of the first connecting part has an arc-shaped portion. The second end of the second connecting part has a recess into which the arc-shaped portion fits. The first connecting part and the second connecting part are connected to each other by the hooking of the first hook part and the second hook part. When the first connecting part is bent toward the second connecting part, the arc-shaped portion of the first end fits into the recess of the second end. When the first connecting portion, which is connected to one of the temple and endpiece sections, is bent toward the second connecting portion, which is connected to the other of the temple and endpiece section, the arc-shaped portion fits into the recess, thereby enabling stable bending of the temple relative to the endpiece section of the front when bending.

[0009] (2) In (1) above, one of the first end and the second end may have a protrusion. The other of the first end and the second end may have a hole into which the protrusion fits. The protrusion and the hole may not be fixed to each other. In this case, the protrusion formed on one of the first end and the second end fits into the hole formed on the other of the first end and the second end. The protrusion fitting into the hole allows the bending motion of the temple relative to the front end to be stable when the connecting member is bent.

[0010] (3) In (1) above, the second end may have a protrusion. The first end may have a hole. In this case, when the first connecting portion is bent toward the second connecting portion, the protrusion formed on the second end can be inserted into the hole formed on the first end. Thus, stability during bending can be more reliably ensured.

[0011] (4) In any of (1) to (3) above, the first end may be cylindrical with an arc-shaped portion. In this case, the cylindrical shape of the first end simplifies the shape of the first end while improving the design of the eyewear, as it allows the wearer to intuitively understand that the temple can be bent 360° freely relative to the front hinge.

[0012] (5) In any of (1) to (4) above, the second connecting part is connected to the temple portion, and the second connecting part may be covered by the temple portion and the first end portion. In this case, the recess of the second connecting part can be covered by the temple portion and also by the first end portion. This makes it difficult to see the recess when the eyewear is viewed from the outside.

[0013] The connecting member according to this disclosure is (6) a connecting member for connecting the endpiece and the temple of eyewear to each other, comprising a first connecting portion connected to one of the temple and the endpiece, and a second connecting portion connected to the other of the temple and the endpiece. The first connecting portion has a first mounting portion attached to one of the temple and the endpiece, and a first hook portion exposed from the first mounting portion. The second connecting portion has a second mounting portion attached to the other of the temple and the endpiece, and a second hook portion exposed from the second mounting portion and hooking onto the first hook portion. At least one of the first mounting portion and the second mounting portion is movable by an elastic body with respect to the portion in which the first hook portion is hooked onto the second hook portion. The first mounting portion has a first end portion that contacts the second mounting portion. The second mounting portion has a second end portion that contacts the first end portion. The first end portion has an arc-shaped portion that protrudes toward the second end portion. The second end has a recess into which the arc-shaped portion of the first connecting portion fits when the first connecting portion is bent toward the second connecting portion. This connecting member, like the eyewear described above, has a recess at its second end. The arc-shaped portion of the first end fits into the recess when the first connecting portion is bent toward the second connecting portion. Therefore, the same effect as the eyewear described above can be obtained from this connecting member. [Effects of the Invention]

[0014] According to this disclosure, the bending motion of the temple relative to the front can be performed stably. [Brief explanation of the drawing]

[0016] The embodiments of the eyewear and connecting members relating to this disclosure will be described below with reference to the drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. For the sake of ease of understanding, some parts of the drawings may be simplified or exaggerated, and the dimensional ratios, etc., are not limited to those shown in the drawings.

[0017] In the present disclosure, "eyewear" means an instrument worn so as to cover the eyes of a user. "Eyewear" includes glasses for correcting refractive errors of the eyes such as myopia, hyperopia or astigmatism, sunglasses for decorating the periphery of the eyes, and goggles for protecting the eyes. Further, in the present disclosure, "temple" means, in eyewear, a pair of rod-shaped portions facing the temples and ears of the user when the eyewear is worn. The temple is also referred to as a vine or an arm.

[0018] FIG. 1 is a perspective view showing eyewear 1 and a connecting member 10 according to an embodiment. The eyewear 1 includes a frame 2, a lens L, and a connecting member 10. The frame 2 has temples 3 and a front 4. The frame 2 has a pair of temples 3. The temple 3 is, for example, rod-shaped. The material of the frame 2 is, for example, resin.

[0019] Hereinafter, the extending direction of the temple 3 will be described as the first direction D1, the direction in which the pair of temples 3 are arranged as the second direction D2, and the direction orthogonal to both the first direction D1 and the second direction D2 as the third direction D3. However, these directions are for convenience of explanation and do not limit the arrangement position or direction of an object. Further, when viewed from a user wearing the eyewear 1, the front may be referred to as "front", "forward" or "front side", the rear as "rear", "rearward" or "rear side", the upper as "upper", "upward" or "upper side", and the lower as "lower", "downward" or "lower side".

[0020] For example, the temple 3 has a rear end portion 3a. The rear end portion 3a is located on the side opposite to the front 4 in the temple 3. For example, the width of the rear end portion 3a in the third direction D3 is larger than the width of the portion of the temple 3 excluding the rear end portion 3a in the third direction D3. The pair of rear end portions 3a may be curved in a direction facing each other.

[0021] The front 4 extends in the second direction D2. The front 4 connects the front ends 3b of a pair of temples 3 to each other. The front 4 has a hinge portion 4b, a bridge 4c, a rim 4d, and a pad 4e.

[0022] The front 4 has a pair of rims 4d. The rims 4d are located on each side of the front 4 in a second direction D2. The pair of rims 4d are aligned in the second direction D2. The rims 4d are annular. For example, the length of the rim 4d in the second direction D2 is longer than the length of the rim 4d in the third direction D3. The rim 4d has a first edge 4a, a second edge 4f, and a third edge 4g.

[0023] The bridge 4c is interposed between a pair of rims 4d. The bridge 4c is located in the center of the second direction D2 on the front 4. The bridge 4c is located on one side (upper side) of the third direction D3. The bridge 4c is connected to the first edge 4a of the rim 4d. The first edge 4a extends downward from the bridge 4c and extends to the center of the rim 4d in the second direction D2. The first edge 4a is located on the rim 4d closer to the bridge 4c in the second direction D2. The pair of first edges 4a are aligned in the second direction D2.

[0024] The second edge portion 4f extends from the hinge portion 4b to the bridge 4c. The second edge portion 4f is located on one side (upper side) of the third direction D3 in the rim 4d. The second edge portion 4f extends in the second direction D2. A pair of second edge portions 4f are aligned in the second direction D2. One end of the second edge portion 4f is connected to the bridge 4c. The other end of the second edge portion 4f is connected to the hinge portion 4b.

[0025] The third edge portion 4g extends downward from the hinge portion 4b and extends to the center of the rim 4d in the second direction D2. The third edge portion 4g is located on the opposite side (lower side) of the bridge 4c in the rim 4d. The third edge portion 4g extends in the third direction D3. A pair of third edge portions 4g are aligned in the second direction D2. One end of the third edge portion 4g in the third direction D3 is connected to the hinge portion 4b.

[0026] The endpiece portion 4b extends in a roughly L-shape in plan view from the second edge portion 4f and the third edge portion 4g toward the temple 3. The portion of the endpiece portion 4b that connects to the temple 3 is, for example, shaped like a rectangular parallelepiped. For example, the length of the endpiece portion 4b in the first direction D1 is longer than the length of the endpiece portion 4b in the second direction D2 and the length of the endpiece portion 4b in the third direction D3. The front 4 has a pair of endpiece portions 4b. The pair of endpiece portions 4b are aligned in the second direction D2.

[0027] Pad 4e is a nose pad that contacts the user's nose. The material of pad 4e is, for example, silicone resin. Pad 4e is formed on the first edge 4a of the rim 4d. Pad 4e protrudes rearward from the rim 4d. The front 4 is equipped with a pair of pads 4e. The pair of pads 4e are placed against the user's nose so as to sandwich it from both sides in the second direction D2. The shape, size, and material of pad 4e can be changed as appropriate.

[0028] The lens L is fitted into the rim 4d. Eyewear 1 has a pair of lenses L. The pair of lenses L are aligned in the second direction D2. The lenses L are, for example, plastic lenses, but may also be glass lenses. The lenses L may be spherical or aspherical, such as planar.

[0029] Lens L may be a lens for correcting vision, a contrast lens, or a polarizing lens. Lens L may also be a lens without photochromic or polarizing functions, or a lens that does not correct vision. Thus, various types of lenses can be used as lens L.

[0030] The connecting member 10 is a component that connects the hinge portion 4b and the temple 3 to each other. The connecting member 10 is interposed between the front 4 (hinge portion 4b) and the temple 3 (front end portion 3b). The eyewear 1 has a pair of connecting members 10. The pair of connecting members 10 are aligned in the second direction D2. The material of the connecting member 10 is, for example, metal.

[0031] The connecting member 10 rotatably connects the temples 3 to the front 4. The connecting member 10 allows the temples 3 to move up, down, left, and right relative to the front 4. The connecting member 10 allows the frame 2 to be opened and closed. "Closing the frame" means bending the pair of temples 3 toward each other relative to the front 4, and "opening the frame" means bending the pair of temples 3 toward each other. "Opening and closing the frame" refers to the actions of "closing the frame" and "opening the frame".

[0032] Figure 2 is an enlarged perspective view showing the connecting member 10 of the eyewear 1. Figure 3 is a perspective view showing the first connecting portion 20 and the second connecting portion 30 of the connecting member 10 in Figure 2. As shown in Figures 1, 2, and 3, the connecting member 10 has a first connecting portion 20 and a second connecting portion 30. When the eyewear 1 is assembled, the first connecting portion 20 and the second connecting portion 30 are aligned along the first direction D1.

[0033] When the eyewear 1 is assembled, the first connecting portion 20 (the first end portion 22, described later) of the connecting member 10 is easily visible when the eyewear 1 is worn, while most of the parts of the connecting member 10 other than the first end portion 22 are hidden by the resin that makes up the temple 3 and the endpiece portion 4b. As a result, the exposure of the mechanical parts of the connecting member 10 is reduced, and the design of the eyewear 1 can be enhanced by creating a simple appearance in which metal parts connect the temple 3 and the endpiece portion 4b.

[0034] The first connecting portion 20 is connected to the temple 3. The temple 3 has a hollow interior. A part of the first connecting portion 20 (the first mounting portion 21, described later) is inserted into the hollow of the temple 3. The first connecting portion 20 is connected to the temple 3 with a part of it inserted into the hollow of the temple 3.

[0035] The first connecting portion 20 has a first mounting portion 21 and a first hook portion 23. The first mounting portion 21 has a first end portion 22. The first mounting portion 21 is the part for attaching the first connecting portion 20 to the temple 3. The first connecting portion 20 is attached to the temple 3 by inserting the first mounting portion 21 into the cavity of the temple 3. The first mounting portion 21 is, for example, cylindrical (in one example, cylindrical). The first mounting portion 21 extends, for example, in a first direction D1.

[0036] The first mounting portion 21 has, for example, a cylindrical portion 21b. The first end portion 22 is connected to one end of the cylindrical portion 21b in a first direction D1. The first end portion 22 is, for example, cylindrical. As described above, when the eyewear 1 is assembled, the cylindrical first end portion 22 of the connecting member 10 is easily visible from the outside. This enhances the aesthetic design of the eyewear 1.

[0037] For example, the width in the second direction D2 of the cross-section of the first end portion 22 perpendicular to the first direction D1 is greater than the width in the second direction D2 of the cross-section of the first mounting portion 21 perpendicular to the first direction D1. For example, the first end portion 22 has a first surface 22a and a second surface 22b. The first surface 22a is the top and bottom surfaces of the cylindrical first end portion 22, and the second surface 22b is the side surface of the cylindrical first end portion 22.

[0038] The first surface 22a is, for example, a surface facing the third direction D3. The first surface 22a is, for example, circular when viewed from the third direction D3. However, the shape of the first surface 22a is not limited to a perfect circle, and may be, for example, an oval shape. The first end portion 22 has a pair of first surfaces 22a aligned along the third direction D3, and the second surface 22b extends in the third direction D3 between the pair of first surfaces 22a. The second surface 22b is, for example, a surface facing a direction perpendicular to the third direction D3. At least a part of the second surface 22b is an arc-shaped surface. One end of the cylindrical portion 21b is connected to the second surface 22b.

[0039] The first end portion 22 has an arc-shaped portion 22c. The arc-shaped portion 22c is part of the first end portion 22. The arc-shaped portion 22c is, for example, the portion of the first end portion 22 opposite to the cylindrical portion 21b. The arc-shaped portion 22c includes, for example, the portion where the first surface 22a intersects with the second surface 22b. The arc-shaped portion 22c includes the portion where the first surface 22a and the second surface 22b connect to each other.

[0040] The first end portion 22 has an opening 22f. A first hook portion 23 protrudes from the opening 22f. The opening 22f faces away from the cylindrical portion 21b. The opening 22f is formed on the second surface 22b. The first end portion 22 has, for example, a pair of first portions 22d, which are disc-shaped portions located above and below the opening 22f, and a second portion 22e, which is located between the pair of first portions 22d. The first portions 22d include a first surface 22a and a second surface 22b. The second portion 22e protrudes from the inner surface of the first portion 22d opposite to the first surface 22a. The second portion 22e is, for example, rod-shaped.

[0041] The first end portion 22 has a hole 22g. The hole 22g is formed on the second surface 22b of the first end portion 22. For example, the length of the first end portion 22 in the outer circumference direction at the hole 22g is shorter than the length of the hole 22g in the third direction D3. "Outer circumference direction of the first end portion 22" means the direction along a ring centered on a virtual axis that passes through the center of the cylindrical first end portion 22 and extends in the third direction D3.

[0042] The hole 22g is located, for example, at one end of the first end 22 in the outer circumferential direction of the opening 22f. For example, the hole 22g is continuous with the opening 22f. In this case, the hole 22g is located at one end of the opening 22f in the outer circumferential direction. However, the hole 22g may be formed separately from the opening 22f.

[0043] The first hook portion 23 is exposed from the first mounting portion 21. The first hook portion 23 is exposed from the first end portion 22. The first hook portion 23 is exposed from the opening 22f in the first direction D1. For example, the first hook portion 23 is fixed inside the first mounting portion 21 and extends in the first direction D1 inside the first mounting portion 21. The first hook portion 23 is, for example, hook-shaped. For example, when viewed from the third direction D3, the first hook portion 23 is J-shaped. The first hook portion 23 may also be J-shaped when viewed from the first direction D1, and the orientation of the first hook portion 23 is not particularly limited. The first hook portion 23 will be described in detail later.

[0044] The second connecting portion 30 is connected to the armor portion 4b. The armor portion 4b has a cavity inside. The second connecting portion 30 is, for example, inserted into the cavity of the armor portion 4b. In this way, the second connecting portion 30 is connected to the armor portion 4b, and a part of the second connecting portion 30 is covered by the armor portion 4b.

[0045] The second connecting portion 30 has a second mounting portion 31 and a second hook portion 33. The second mounting portion 31 has a second end portion 32. The second mounting portion 31 is attached to the armor portion 4b. The second mounting portion 31 is, for example, rectangular parallelepiped. However, the second mounting portion 31 may be cylindrical (in one example, rectangular cylindrical), and the shape of the second mounting portion 31 is not particularly limited.

[0046] The second mounting portion 31 has, for example, a first through hole 31a. The first through hole 31a penetrates the second mounting portion 31 in a third direction D3. A screw (not shown) is inserted into the first through hole 31a to fix the second connecting portion 30, which is inserted into the cavity of the armor portion 4b, to the armor portion 4b. By inserting this screw into the armor portion 4b and the first through hole 31a, the second connecting portion 30 is fixed to the armor portion 4b.

[0047] The second mounting portion 31 has, for example, a box-shaped portion 31b. The second end portion 32 is adjacent to the box-shaped portion 31b in, for example, the first direction D1. That is, the second end portion 32 is aligned with the box-shaped portion 31b along the first direction D1. The second end portion 32 is, for example, a rectangular parallelepiped. However, the second end portion 32 may be cylindrical (in one example, a rectangular cylinder), and the shape of the second end portion 32 is not particularly limited. For example, the length of the second end portion 32 in the second direction D2 is longer than the length of the box-shaped portion 31b in the second direction D2. For example, the length of the second end portion 32 in the third direction D3 is longer than the length of the box-shaped portion 31b in the third direction D3.

[0048] The second end portion 32 has, for example, a first side surface 32b, a second side surface 32f intersecting the first side surface 32b, and a third side surface 32g intersecting both the first side surface 32b and the second side surface 32f. The second end portion 32 has a recess 32a. The recess 32a is recessed in the first side surface 32b. When the temple 3 is bent, the arc-shaped portion 22c of the first end portion 22 of the first connecting portion 20 fits into the recess 32a.

[0049] The first side surface 32b is, for example, the surface of the second end portion 32 facing the third direction D3 (upward). The recess 32a is, for example, located on the opposite side from the box-shaped portion 31b from the center of the second end portion 32. The second end portion 32 may have, for example, multiple (two in one example) recesses 32a. In this case, the recesses 32a are formed on each of the first side surfaces 32b facing both sides of the third direction D3. That is, recesses 32a are formed on both the upper and lower sides of the second end portion 32.

[0050] For example, when viewed from the third direction D3, the recess 32a is rectangular in shape. The length of the recess 32a in the second direction D2 is longer than the length of the recess 32a in the first direction D1. The depth of the recess 32a may or may not be constant. For example, the depth of the recess 32a increases towards the center of the recess 32a in the second direction D2. For example, when the recess 32a is cut along a plane extending in the second direction D2 and the third direction D3, the cross-section is arc-shaped.

[0051] In this case, the radius of curvature of the arc-shaped portion of the cross-section of the recess 32a may be greater than the radius of curvature of the aforementioned arc-shaped portion 22c. For example, the thickness of the arc-shaped portion 22c is smaller than the width of the recess 32a in the first direction D1.

[0052] Figure 4(a) is an enlarged perspective view from the wearer's side (inside) when wearing the eyewear 1, showing the first connecting part 20 connected to the temple 3 and the second connecting part 30 connected to the endpiece part 4b. As shown in Figure 4(a), when the temple 3 and the endpiece part 4b are aligned in a straight line, the recess 32a and the first side surface 32b (see Figure 2) are covered in the third direction D3 (up and down direction) by the arc-shaped portion 22c of the first end 22 of the first connecting part 20 and the endpiece part 4b, making them difficult to see from the outside. The portion of the endpiece part 4b facing the arc-shaped portion 22c may be arc-shaped along the arc-shaped portion 22c.

[0053] Figure 4(b) is a perspective view showing the connecting member 10 in a state where the temple 3 is further bent in the opening direction D2 from the state shown in Figure 4(a). As shown in Figure 4(b), when the temple 3 is further bent in the opening direction, a portion of the recess 32a and the first side surface 32b is exposed from the first end portion 22, and the remainder of the first side surface 32b is covered by the hinge portion 4b. The manner in which the temple 3 is bent will be described in detail later.

[0054] The second connecting portion 30 is covered by the hinge portion 4b and the first end portion 22. More specifically, the box-shaped portion 31b (see Figure 3) and the third side surface 32g of the second connecting portion 30 are covered by the hinge portion 4b. The first side surface 32b and the recess 32a are covered by the hinge portion 4b and the arc-shaped portion 22c of the first end portion 22. When the temple 3 is bent in the second direction D2 or the third direction D3 relative to the hinge portion 4b, the second side surface 32f and the second hook portion 33 are exposed when viewed from a direction other than the inside.

[0055] As described above, when the eyewear 1 is assembled, the recess 32a is difficult to see. The cylindrical first end portion 22 of the first connecting portion 20 is easily visible externally, which improves the aesthetic appeal of the eyewear 1 and prevents foreign objects from entering the recess 32a, which is covered vertically by the arc-shaped portion 22c of the first end portion 22.

[0056] The explanation will be given again with reference to Figures 2 and 3. The second end portion 32 has a protrusion 32c. The protrusion 32c is located, for example, at the tip of the second end portion 32 in the first direction D1. The protrusion 32c is formed at the corner 32h of the second end portion 32. The corner 32h is located at the corner of the first side surface 32b and extends along the third direction D3. The protrusion 32c projects obliquely at the corner 32h with respect to both the first direction D1 and the second direction D2.

[0057] The second end portion 32 has, for example, a projection 32d. The projection 32d is located, for example, at the tip of the second end portion 32 in a first direction D1. The projection 32d is formed at a corner 32k that is different from the corner 32h where the convex portion 32c is provided. The projection 32d is aligned with the convex portion 32c along a second direction D2, for example.

[0058] The second hook portion 33 is exposed from the second mounting portion 31. The second hook portion 33 is exposed from the second end portion 32. For example, the second end portion 32 has an internal space that accommodates the second hook portion 33 and an opening that communicates with the internal space and is formed on the second side surface 32f, and the second hook portion 33 is exposed from the opening in the first direction D1. For example, the second hook portion 33 is fixed inside the second end portion 32, and a part of the second hook portion 33 protrudes from the second end portion 32. The second hook portion 33 is annular when viewed from the second direction D2, for example. The second hook portion 33 may also be annular when viewed from the third direction D3, and the orientation of the second hook portion 33 is not particularly limited.

[0059] As described above, the first hook portion 23 is hook-shaped, and the second hook portion 33 is annular. The first hook portion 23 hooks onto the second hook portion 33. Alternatively, the first hook portion 23 may be annular and the second hook portion 33 may be hook-shaped. The second end portion 32 has, for example, a second through hole 32e. The second through hole 32e penetrates the second end portion 32 in the second direction D2. A screw (not shown) is inserted into the second through hole 32e to fix the second hook portion 33, which is inserted into the internal space of the second end portion 32, to the second end portion 32. By inserting this screw into the second through hole 32e and the second hook portion 33, the second hook portion 33 is fixed to the second end portion 32.

[0060] Figure 5 is an exploded perspective view showing the connecting member 10. As shown in Figures 3 and 5, a portion of the first hook portion 23 is located inside the first mounting portion 21 (cylindrical portion 21b). The first hook portion 23 extends, for example, in a first direction D1. The first hook portion 23 has, for example, a portion 23a that is housed inside the first mounting portion 21, and this portion 23a is, for example, rod-shaped.

[0061] A portion of the second hook portion 33 is located in the internal space of the second end portion 32. The second hook portion 33 extends, for example, in the first direction D1. The second hook portion 33 has, for example, a portion 33a that is housed inside the second end portion 32, and this portion 33a is, for example, plate-shaped.

[0062] The second hook portion 33 has, for example, a hole 33b. The hole 33b penetrates portion 33a of the second hook portion 33 in the second direction D2. The aforementioned screw (a screw for fixing the second hook portion 33 to the second end portion 32) is inserted into the hole 33b. By inserting this screw into the second through hole 32e and the hole 33b of the second end portion 32, the second hook portion 33 is fixed to the second end portion 32.

[0063] The connecting member 10 has a first elastic body 41 and a second elastic body 42 (elastic bodies). The first elastic body 41 and the second elastic body 42 are, for example, expandable and contractible in a first direction D1. In one example, the first elastic body 41 and the second elastic body 42 are coil springs (helical springs). The first elastic body 41 and the second elastic body 42 are springs that have elasticity against compressive force. When subjected to an external force, the first elastic body 41 and the second elastic body 42 generate a repulsive force that rebounds against the external force.

[0064] The first elastic body 41 is located inside the first connecting portion 20. For example, the first elastic body 41 is located on the outer circumference of the portion 23a of the first hooking portion 23 that is not exposed from the first end portion 22. The second elastic body 42 is located inside the second connecting portion 30. The second elastic body 42 is located alongside the second hooking portion 33 in the first direction D1. The length of the first elastic body 41 is longer than the length of the second elastic body 42.

[0065] The first elastic body 41 biases the first hook portion 23 inside the first mounting portion 21. One end of the first elastic body 41 is fixed to the first mounting portion 21, and the other end of the first elastic body 41 is connected to the first hook portion 23. Therefore, the first hook portion 23 is expandable and contractible relative to the first mounting portion 21. The second elastic body 42 biases the second hook portion 33 inside the second end portion 32. One end of the second elastic body 42 is fixed to the second end portion 32, and the other end of the second elastic body 42 is connected to the second hook portion 33. Therefore, the third hook portion 33 is expandable and contractible relative to the second mounting portion 31.

[0066] The first hook portion 23 hooks onto the second hook portion 33, thereby connecting the first mounting portion 21 of the first connecting portion 20 to the second mounting portion 31 of the second connecting portion 30. The second end portion 32 of the second connecting portion 30 connects to the first end portion 22 of the first connecting portion 20. In this way, the first connecting portion 20 and the second connecting portion 30 are connected to each other.

[0067] As shown in Figures 1 and 5, in this embodiment, the first mounting portion 21 of the first connecting portion 20 is inserted into the temple 3, and the second mounting portion 31 of the second connecting portion 30 is inserted into the endpiece portion 4b. The first hook portion 23 is extendable and retractable relative to the first mounting portion 21 by the first elastic body 41, and the second hook portion 33 is extendable and retractable relative to the second mounting portion 31 by the second elastic body 42. The second connecting portion 30 is connected to the first connecting portion 20 by the first hook portion 23 hooking onto the second hook portion 33.

[0068] Therefore, the first mounting portion 21 attached to the temple 3 and the second mounting portion 31 attached to the endpiece portion 4b are movable relative to the portion where the first hooking portion 23 is hooked onto the second hooking portion 33. Consequently, the temple 3 is movable up, down, left, and right relative to the endpiece portion 4b, and is also rotatable about a virtual axis extending in the first direction D1. In other words, the direction of extension of the temple 3 can be freely changed with the endpiece portion 4b as a pivot point, and the temple 3 can be freely bent relative to the endpiece portion 4b.

[0069] Figure 6 is an enlarged perspective view showing the connecting member 10 in a folded state. Figure 6 shows the first connecting portion 20 folded toward the second connecting portion 30. In the examples shown in Figures 1 and 6, the temple 3 is folded so that it moves upward relative to the endpiece portion 4b.

[0070] For example, the first connecting portion 20 is bent 90° relative to the second connecting portion 30. The first mounting portion 21 and the second mounting portion 31 are movable by the first elastic body 41 and the second elastic body 42 with respect to the portion P where the first hooking portion 23 is hooked onto the second hooking portion 33. The first connecting portion 20 is rotatable with respect to the second connecting portion 30 about a virtual straight line that passes through the hooked portion P and extends in the second direction D2 as its central axis. For example, the first connecting portion 20 is rotatable approximately 90° in both directions (up and down) from the first direction D1 to the third direction D3.

[0071] The arc-shaped portion 22c of the first end 22 of the first connecting portion 20 protrudes toward the second end 32 of the second connecting portion 30. The arc-shaped portion 22c fits into the recess 32a of the second end 32 of the second connecting portion 30 when the first connecting portion 20 is bent toward the second connecting portion 30. When the arc-shaped portion 22c fits into the recess 32a, it fits further inward of the second end 32 than the first side surface 32b of the second end 32. At this time, the arc-shaped portion 22c may catch on the inner wall of the recess 32a, in which case the movement of the arc-shaped portion 22c in the first direction D1 is restricted.

[0072] Figure 7 is an enlarged perspective view showing the connecting member 10 in a state where it is bent in a different direction than in Figure 6. In the examples shown in Figures 1 and 7, the temple 3 is bent so that it moves from a first direction D1 to a second direction D2 (opening direction) relative to the endpiece portion 4b. The first connecting portion 20 is rotatable relative to the second connecting portion 30 about a virtual axis that passes through the hooked portion P and extends in a third direction D3.

[0073] For example, the first connecting part 20 is rotatable by approximately 90° on both sides (left and right) of the second direction D2. The first connecting part 20 is rotatable by approximately 90° in both the opening direction and the closing direction, which is the opposite direction to the opening direction. The state in which it is rotated by approximately 90° in the closing direction is the state in which the temple 3 is folded during normal use (the state in which the eyewear 1 is folded when stored). When the temple 3 is bent so as to move in the second direction D2 relative to the hinge part 4b, the protrusion 32c of the second end 32 of the second connecting part 30 fits into the hole 22g of the first end 22 of the first connecting part 20.

[0074] The first connecting portion 20 is movable relative to the second connecting portion 30 in a direction that is inclined with respect to both the second direction D2 and the third direction D3. The first connecting portion 20 is rotatable 360° relative to the second connecting portion 30 with respect to a virtual straight line that passes through the hooked portion P and extends in the first direction D1 as its central axis. In other words, the connecting member 10 allows the temple 3 to rotate 360° relative to the front 4 with respect to a virtual straight line that aligns the temple 3 and the front 4 as its central axis. The connecting member 10 allows the rear end portion 3a of the temple 3 to rotate 360° in a circular motion on a virtual plane parallel to the planes extending in the second direction D2 and the third direction D3.

[0075] Next, the effects and advantages obtained from the eyewear 1 and connecting member 10 according to this embodiment will be described in more detail. In this eyewear 1, the connecting member 10 comprises a first connecting member 20 having a first mounting portion 21 and a first hook portion 23 that are attached to the temple 3, and a second connecting member 30 having a second mounting portion 31 and a second hook portion 33 that are attached to the endpiece portion 4b. The first mounting portion 21 and the second mounting portion 31 are movable by a first elastic body 41 and a second elastic body 42 with respect to the portion P in which the first hook portion 23 is hooked onto the second hook portion 33. The first end portion 22 of the first connecting member 20 has an arc-shaped portion 22c. The second end portion 32 of the second connecting member 30 has a recess 32a into which the arc-shaped portion 22c fits. The first connecting member 20 and the second connecting member 30 are connected to each other by the hooking of the first hook portion 23 and the second hook portion 33.

[0076] When the first connecting portion 20 is bent toward the second connecting portion 30, the arc-shaped portion 22c of the first end portion 22 fits into the recess 32a of the second end portion 32. When the first connecting portion 20 connected to the temple 3 is bent toward the second connecting portion 30 connected to the endpiece portion 4b, the arc-shaped portion 22c fits into the recess 32a. As a result, the first connecting portion 20 is bent toward the second connecting portion 30 with the portion where the arc-shaped portion 22c fits into the recess 32a as the pivot point, thus suppressing deviation in directions other than the bending direction and enabling stable bending. In this embodiment, stability can be ensured when the temple 3 is bent toward the endpiece portion 4b with respect to a virtual axis extending in the second direction D2. Therefore, the bending operation of the temple 3 toward the endpiece portion 4b of the front 4 can be performed stably.

[0077] In this disclosure, "arc-shaped" includes not only arcs but also shapes other than arcs. The "arc-shaped portion" can be any portion that produces the same effects as described above, and may be a portion with a shape other than an arc. Furthermore, even if the material of the first connecting portion 20 and the second connecting portion 30 is metal, the arc-shaped portion 22c fits into the recess 32a and is bent, so the first connecting portion 20 does not come into contact with the resin armor portion 4b, thereby reducing wear on the armor portion 4b.

[0078] In this embodiment, the arc-shaped portion 22c may be in contact with the recess 32a. As described above, the cross-section of the recess 32a when cut along a plane extending in the second direction D2 and the third direction D3 is arc-shaped. Therefore, the contact area of ​​the arc-shaped portion 22c in the recess 32a can be increased compared to the case where the bottom surface of the recess 32a is flat. Consequently, when the temple 3 is bent relative to the endpiece portion 4b, the arc-shaped portion 22c can be brought into surface contact with the recess 32a, thereby stabilizing the bending.

[0079] In this embodiment, the second end portion 32 has a protrusion 32c, and the first end portion 22 has a hole 22g into which the protrusion 32c fits. The protrusion 32c and the hole 22g are not fixed to each other. As the protrusion 32c fits into the hole 22g, the first connecting portion 20 is bent relative to the second connecting portion 30 with that portion as a fulcrum, thereby suppressing displacement in directions other than the bending direction and enabling stable bending. In this embodiment, stability can be ensured when the temple 3 is bent relative to the endpiece portion 4b with respect to a virtual axis extending in the third direction D3. This makes the bending operation of the temple 3 relative to the endpiece portion 4b of the front 4 even more stable.

[0080] In this embodiment, the first end portion 22 is cylindrical with an arc-shaped portion 22c. In this case, the cylindrical shape of the first end portion 22 simplifies the shape of the first end portion 22 while improving the design of the eyewear 1, which allows the wearer to intuitively understand that the temple 3 can be bent 360° freely relative to the hinge portion 4b of the front 4.

[0081] In this embodiment, the second connecting portion 30 is connected to the temple portion 4b. The second connecting portion 30 is covered by the temple portion 4b and the first end portion 22. This makes the recess 32a difficult to see from the outside when the eyewear 1 is viewed from the outside, and also prevents foreign objects from entering the recess 32a.

[0082] Embodiments of the eyewear and connecting members relating to this disclosure have been described above. However, the eyewear and connecting members relating to this disclosure are not limited to the embodiments described above, and may be further modified within the scope of the gist described in the claims. That is, the shape, size, material, number, and arrangement of each part of the eyewear and connecting members relating to this disclosure can be appropriately changed within the scope of the gist described above.

[0083] For example, in the embodiment described above, an example was described in which the first connecting part 20 is connected to the temple 3 and the second connecting part 30 is connected to the endpiece part 4b. However, the first connecting part may be connected to the endpiece part 4b and the second connecting part may be connected to the temple 3.

[0084] In the embodiments described above, an example was described in which the eyewear 1 comprises a first elastic body 41 housed in the first mounting portion 21 and a second elastic body 42 housed in the second mounting portion 31. However, the eyewear may comprise only either the first elastic body 41 housed in the first mounting portion 21 or the second elastic body 42 housed in the second mounting portion 31.

[0085] In the embodiments described above, an example was described in which the second end portion 32 has a protrusion 32c and the first end portion 22 has a hole 22g. However, the first end portion 22 may have a protrusion and the second end portion 32 may have a hole. In the embodiments described above, a first end portion 22 that is cylindrical including an arc-shaped portion 22c was described. However, the first end portion only needs to include an arc-shaped portion, and the overall shape of the first end portion may be a shape other than cylindrical.

[0086] In the embodiment described above, an example was given in which the recess 32a faces both sides of the third direction D3. However, the recess 32a may face directions other than the third direction D3. For example, the recess 32a may face both sides of the second direction D2. [Explanation of symbols]
