Description

Technical Field

[0001] This disclosure relates to eyepieces and connecting components. Background Technology

[0002] Patent Document 1 describes a frame having a front frame, a headstock, and temples. The temples are mounted to the headstock via hinges. The hinges are so-called spring hinges, including springs for holding the temples, allowing the temples to open to a right angle or higher. Patent Document 1 describes both a hinge that rotates around a single axis and a hinge that has two axes. In the hinge with two axes, the hinge rotates around two mutually orthogonal axes.

[0003] Patent Document 2 describes a hinge system for eyeglass frames. This hinge system has a pivot point between a first rigid element and a second rigid element. The ends of each rigid element have paired bearing surfaces. This hinge system is a so-called spring hinge with elastic units to maintain bearing contact. The hinge system has two rotating parts, each having a concave region that serves as a bending surface. The two rotating parts are interlocked via the connection of these concave regions, allowing them to rotate relative to each other like links in a chain.

[0007] [Patent Document 2] Japanese Patent Publication No. 2006-509173 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] In eyeglasses equipped with the aforementioned hinge, the temples can be bent in various directions relative to the front frame via the hinge. However, in Patent Document 1, when the temples are bent in various directions relative to the front frame, the front side element 8 and the base element 15 constituting the hinge are bent in a line or point contact state relative to their respective contact surfaces. Similarly, in Patent Document 2, the first rigid element and the second rigid element are also bent in a line contact state. Therefore, for example, when bending in the vertical direction, there may be wobbling in the left and right direction, and sometimes the bending action of the temples relative to the front frame is unstable.

[0010] The purpose of this invention is to provide an eyepiece and connecting component that, although a spring hinge, can stably perform the bending motion of the temple relative to the front frame.

[0011] Methods for solving problems

[0012] The eyepiece (1) disclosed herein includes a frame having a front frame including a post and temples, and the eyepiece includes a connecting member connecting the post and temples. The connecting member includes: a first connecting portion connecting to one of the temples and the post; and a second connecting portion connecting to the other of the temples and the post. The first connecting portion includes: a first mounting portion mounted to one of the temples and the post; and a first latching portion protruding from the first mounting portion. The second connecting portion includes: a second mounting portion mounted to the other of the temples and the post; and a second latching portion protruding from the second mounting portion and latching onto the first latching portion. At least one of the first mounting portion and the second mounting portion is configured to be movable relative to the portion of the first latching portion that latches onto the portion of the second latching portion by means of an elastic body. The first mounting portion has a first end portion contacting the second mounting portion. The second mounting portion has a second end portion contacting the first end portion. The first end portion has an arcuate portion protruding toward the second end portion. The second end portion has a recess into which the arcuate portion enters when the first connecting portion is bent toward the second connecting portion.

[0013] In this eyewear, the connecting component includes: a first connecting portion having a first mounting portion and a first hook portion mounted on one of the temple and the head of the eyepiece; and a second connecting portion having a second mounting portion and a second hook portion mounted on the other of the temple and the head of the eyepiece. At least one of the first mounting portion and the second mounting portion is configured to be movable relative to the portion of the first hook portion that is hooked onto the portion of the second hook portion by an elastic body. The first end of the first connecting portion has an arcuate portion. The second end of the second connecting portion has a recess into which the arcuate portion enters. The first connecting portion and the second connecting portion are connected to each other by the hooking of the first hook portion and the second hook portion. When the first connecting portion is bent toward the second connecting portion, the arcuate portion of the first end portion enters the recess of the second end portion. When the first connecting portion, which is connected to one of the temple and the head of the eyepiece, is bent toward the second connecting portion, which is connected to the other of the temple and the head of the eyepiece, the arcuate portion enters the recess, thereby enabling stable bending of the temple relative to the head of the front frame during bending.

[0014] (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 also have a hole into which the protrusion enters. The protrusion and the hole may also not be fixed to each other. In this case, the protrusion formed on one of the first end and the second end enters the hole formed on the other of the first end and the second end. By allowing the protrusion to enter the hole, the bending action of the temple relative to the head of the front frame can be stably performed when the connecting member is bent.

[0015] (3) In (1) above, the second end may have a protrusion. The first end may also have a hole. In this case, when the first connecting portion is bent toward the second connecting portion, the protrusion formed at the second end can enter the hole formed at the first end. Therefore, stability during bending can be ensured more reliably.

[0016] (4) In any of (1) to (3) above, the first end can also be set as a cylinder with an arc-shaped portion. In this case, by making the first end cylindrical, the shape of the first end can be simplified, and as an eyepiece that allows the temple to bend freely 360° relative to the front frame, the appearance can be improved.

[0017] (5) In any of (1) to (4) above, the second connecting part may be connected to the pile head, and the second connecting part may be covered by the pile head and the first end. In this case, the pile head can cover the recess of the second connecting part, and the first end can cover the recess of the second connecting part. Thus, when the eyepiece is observed from the outside, the recess can be made difficult to see.

[0018] The connecting member (6) of this disclosure connects the stud head of an eyeglass to the temple. The connecting member includes: a first connecting portion connected to one of the temple and the stud head; and a second connecting portion connected to the other of the temple and the stud head. The first connecting portion has: a first mounting portion mounted to one of the temple and the stud head; and a first latching portion protruding from the first mounting portion. The second connecting portion has: a second mounting portion mounted to the other of the temple and the stud head; and a second latching portion protruding from the second mounting portion and latching onto the first latching portion. At least one of the first mounting portion and the second mounting portion is configured to be movable relative to the portion of the first latching portion that latches onto the second latching portion via an elastic body. 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 arcuate portion protruding toward the second end portion. The second end portion has a recess into which the arcuate portion enters when the first connecting portion is bent toward the second connecting portion. Similar to the eyeglass described above, the second end portion of this connecting member also has a recess. When the first connecting portion is bent toward the second connecting portion, the arc-shaped portion at the first end enters the recess. Therefore, the same effect as the aforementioned eyepiece can be obtained from this connecting component.

[0028] Hereinafter, embodiments of the eyepiece and connecting components of this disclosure will be described with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are labeled with the same reference numerals, and repeated descriptions are omitted where appropriate. For ease of understanding, parts of the drawings are sometimes simplified or exaggerated, and the size ratios are not limited to those shown in the drawings.

[0029] In this disclosure, "eyewear" refers to an apparatus worn to cover a user's eyes. "Eyewear" includes eyeglasses that correct refractive errors such as myopia, hyperopia, or astigmatism, sunglasses that decorate the periphery of the eyes, and protective goggles. Additionally, in this disclosure, "temples" refers to a pair of rod-shaped parts in an eyewear apparatus that are positioned opposite the user's temples and ears when the eyewear is worn. Temples are also referred to as legs or arms.

[0030] Figure 1 This is a perspective view showing the eyepiece 1 and connecting member 10 according to the embodiment. The eyepiece 1 includes a frame 2, a lens L, and a connecting member 10. The frame 2 has temples 3 and a front frame 4. The frame 2 has a pair of temples 3. The temples 3 are, for example, rod-shaped. The material of the frame 2 is, for example, resin.

[0031] Hereinafter, the direction in which the temple 3 extends is defined as the first direction D1, the direction in which the pair of temples 3 are arranged is defined as the second direction D2, and the direction orthogonal to both the first direction D1 and the second direction D2 is defined as the third direction D3. However, these directions are for ease of explanation and do not limit the position or orientation of the object. In addition, from the perspective of the user wearing the eyeglasses 1, sometimes "front" is defined as "front," "forefront," or "front side," "back" is defined as "back," "rear," or "rear side," "above" is defined as "up," "above," or "upper side," and "below" is defined as "below," "below," or "lower side."

[0032] For example, the temple 3 has a rear end portion 3a. The rear end portion 3a is located on the side of the temple 3 opposite to the front frame 4. For example, the width of the third direction D3 of the rear end portion 3a is greater than the width of the third direction D3 of the portion of the temple 3 other than the rear end portion 3a. The pair of rear ends 3a may also be bent in opposite directions.

[0033] The front frame 4 extends along the second direction D2. The front frame 4 connects the front ends 3b of a pair of temples 3 to each other. The front frame 4 has a headstock 4b, a nose bridge 4c, a frame 4d, and a support pad 4e.

[0034] The front frame 4 has a pair of lens frames 4d. The lens frames 4d are located on both sides of the front frame 4 in the second direction D2. The pair of lens frames 4d are arranged in the second direction D2. The lens frames 4d are annular. For example, the length of the lens frames 4d in the second direction D2 is longer than the length of the lens frames 4d in the third direction D3. The lens frames 4d have a first edge 4a, a second edge 4f, and a third edge 4g.

[0035] A nose bridge 4c is positioned between a pair of frames 4d. The nose bridge 4c is located at the center of the front frame 4 in the second direction D2. The nose bridge 4c is located on one side (upper side) in the third direction D3. The nose bridge 4c is connected to the first edge 4a of the frame 4d. The first edge 4a extends downward from the nose bridge 4c and reaches the center of the frame 4d in the second direction D2. The first edge 4a is located on the frame 4d in the second direction D2 near the nose bridge 4c. A pair of first edge 4a are arranged in the second direction D2.

[0036] The second edge 4f extends from the head of the frame 4b to the nose bridge 4c. The second edge 4f is located on the upper side of the third direction D3 on the frame 4d. The second edge 4f extends along the second direction D2. A pair of second edges 4f are arranged in the second direction D2. One end of the second edge 4f is connected to the nose bridge 4c. The other end of the second edge 4f is connected to the head of the frame 4b.

[0037] The third edge 4g extends downward from the head 4b and reaches the center of the frame 4d in the second direction D2. The third edge 4g is located on the lower side of the frame 4d opposite to the nose bridge 4c. The third edge 4g extends along the third direction D3. A pair of third edges 4g are arranged in the second direction D2. The end of the third edge 4g in the third direction D3 is connected to the head 4b.

[0038] The head of the eyepiece 4b extends in a roughly L-shape from the second edge 4f and the third edge 4g toward the temple 3 when viewed from above. The portion of the head of the eyepiece 4b that connects to the temple 3 is, for example, cuboid in shape. For example, the length of the head of the eyepiece 4b in the first direction D1 is longer than the length of the head of the eyepiece 4b in the second direction D2 and the length of the head of the eyepiece 4b in the third direction D3. The front frame 4 has a pair of head of the eyepiece 4b. The pair of head of the eyepiece 4b is arranged in the second direction D2.

[0039] The nose pad 4e is a nose pad that contacts the user's nose. The material of the nose pad 4e is, for example, silicone. The nose pad 4e is formed on the first edge 4a of the frame 4d. The nose pad 4e protrudes rearward from the frame 4d. The front frame 4 has a pair of nose pads 4e. The pair of nose pads 4e abut against the user's nose by clamping it from both sides of the second direction D2. The shape, size, and material of the nose pads 4e can be appropriately changed.

[0040] Lens L is fitted into frame 4d. Eyepiece 1 has a pair of lenses L. The pair of lenses L are arranged in the second direction D2. Lens L is, for example, a plastic lens, but it can also be a glass lens. Lens L can be spherical, planar, or other aspherical shapes.

[0041] Lens L can be a lens used to correct vision, or it can be a contrast lens or a polarized lens. Lens L can be a lens without light-adjusting or polarizing functions, or it can be a lens that does not correct vision. Thus, various types of lenses can be used as lens L.

[0042] The connecting component 10 is a part that connects the head 4b and the temple 3 to each other. The connecting component 10 is located between the front frame 4 (head 4b) and the temple 3 (front end 3b). The eyepiece 1 has a pair of connecting components 10. The pair of connecting components 10 are arranged in a second direction D2. The material of the connecting component 10 is, for example, metal.

[0043] The connecting component 10 rotatably connects the temples 3 to the front frame 4. Through the connecting component 10, the temples 3 can move up, down, left, and right relative to the front frame 4. The connecting component 10 allows the frame 2 to be opened and closed. "Closing the frame" refers to bending a pair of temples 3 towards each other relative to the front frame 4; "opening the frame" refers to bending a pair of temples 3 away from each other. "Opening and closing the frame" refers to the actions of "closing the frame" and "opening the frame."

[0044] Figure 2 This is an enlarged perspective view of the connecting component 10 of the eyepiece 1. Figure 3 It means Figure 2 A perspective view of the first connecting portion 20 and the second connecting portion 30 of the connecting member 10. (See figure) Figure 1 , Figure 2 and Figure 3 As shown, the connecting member 10 has a first connecting portion 20 and a second connecting portion 30. When the eyepiece 1 is assembled, the first connecting portion 20 and the second connecting portion 30 are arranged along the first direction D1.

[0045] With the eyeglass 1 assembled, the first connecting portion 20 (first end 22, described later) of the connecting member 10 is easily visually identifiable when the eyeglass 1 is worn. Most of the portion of the connecting member 10 other than the first end 22 is covered by the resin that forms the temple 3 and the headstock 4b. This reduces the exposure of the mechanical parts of the connecting member 10, and thus the simple appearance of the metal parts connecting the temple 3 and the headstock 4b improves the aesthetic design of the eyeglass 1.

[0046] The first connecting part 20 is connected to the temple 3. The temple 3 has a cavity inside. A portion of the first connecting part 20 (the first mounting part 21 described later) enters the cavity of the temple 3. The first connecting part 20 is connected to the temple 3 with a portion of it entering the cavity of the temple 3.

[0047] 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 portion for mounting the first connecting portion 20 to the temple 3. The first connecting portion 20 is mounted to the temple 3 by inserting the first mounting portion 21 into the hole 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, along a first direction D1.

[0048] The first mounting portion 21 has, for example, a cylindrical portion 21b. A 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 eyepiece 1 is assembled, the cylindrical first end portion 22 in the connecting member 10 is easily visible. This improves the aesthetic design of the eyepiece 1.

[0049] For example, the width of the cross section of the first end portion 22 orthogonal to the first direction D1 in the second direction D2 is larger than the width of the cross section of the first mounting portion 21 orthogonal to the first direction D1 in the second direction D2. 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.

[0050] The first surface 22a is, for example, a surface facing a 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; it can also be, for example, an oblong shape. The first end portion 22 has a pair of first surfaces 22a arranged along the third direction D3, and a second surface 22b extends along the third direction D3 between the pair of first surfaces 22a. The second surface 22b is, for example, a surface facing a direction orthogonal to the third direction D3. At least a portion of the second surface 22b is an arc-shaped surface. One end of the cylindrical portion 21b is connected to the second surface 22b.

[0051] The first end portion 22 has an arc-shaped portion 22c. The arc-shaped portion 22c is a part of the first end portion 22. For example, the arc-shaped portion 22c is a 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 and the second surface 22b intersect. The arc-shaped portion 22c includes the portion where the first surface 22a and the second surface 22b are connected to each other.

[0052] The first end portion 22 has an opening 22f. A first latching portion 23 protrudes from the opening 22f. The opening 22f faces in the opposite direction to 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 located above and below the opening 22f, and a second portion 22e located between the pair of first portions 22d. The first portion 22d includes 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.

[0053] 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 peripheral direction of the hole 22g is shorter than the length of the third direction D3 of the hole 22g. "The outer peripheral direction of the first end portion 22" refers to the direction along a ring centered on an imaginary axis that passes through the center of the cylindrical first end portion 22 and extends along the third direction D3.

[0054] The hole 22g is located, for example, at one end of the first end portion 22 in the opening 22f in the outer peripheral direction. For example, the hole 22g is continuous from the opening 22f. In this case, the hole 22g is located at one end of the opening 22f in the outer peripheral direction. However, the hole 22g may also be formed separately from the opening 22f.

[0055] The first latching portion 23 protrudes from the first mounting portion 21. The first latching portion 23 protrudes from the first end portion 22. The first latching portion 23 protrudes from the opening 22f in a first direction D1. For example, the first latching portion 23 is fixed inside the first mounting portion 21 and extends along the first direction D1 inside the first mounting portion 21. The first latching portion 23 is, for example, hook-shaped. For example, when viewed from a third direction D3, the first latching portion 23 is J-shaped. The first latching portion 23 may also be J-shaped when viewed from the first direction D1, and the orientation of the first latching portion 23 is not particularly limited. The first latching portion 23 will be described in detail later.

[0056] The second connecting portion 30 is connected to the pile head 4b. The pile head 4b has a cavity inside. The second connecting portion 30, for example, enters the cavity of the pile head 4b. In this way, the second connecting portion 30 is connected to the pile head 4b, and a portion of the second connecting portion 30 is covered by the pile head 4b.

[0057] The second connecting portion 30 has a second mounting portion 31 and a second latching portion 33. The second mounting portion 31 has a second end portion 32. The second mounting portion 31 is mounted on the pile head 4b. The second mounting portion 31 is, for example, cuboid in shape. However, the second mounting portion 31 may also be formed in a cylindrical shape (in one example, a square cylindrical shape), and the shape of the second mounting portion 31 is not particularly limited.

[0058] The second mounting portion 31, for example, has 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, which is used to fix the second connecting portion 30, which is inserted into the hole in the pile head 4b, to the pile head 4b. The second connecting portion 30 is fixed to the pile head 4b by inserting the screw into the pile head 4b and the first through hole 31a.

[0059] The second mounting portion 31, for example, has a box-shaped portion 31b. The second end portion 32, for example, is adjacent to the box-shaped portion 31b in the first direction D1. That is, the second end portion 32 is arranged along the first direction D1 with the box-shaped portion 31b. The second end portion 32 is, for example, cuboid in shape. However, the second end portion 32 may also be cylindrical (in one example, a square tube), 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.

[0060] 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 enters the recess 32a.

[0061] The first side surface 32b is, for example, the surface of the second end 32 facing the third direction D3 (above). The recess 32a is, for example, located on the opposite side of the box-shaped portion 31b from the center of the second end 32. The second end 32 may also have multiple (two in one example) recesses 32a. In this case, the recesses 32a are formed on the first side surface 32b on both sides facing the third direction D3. That is, recesses 32a are formed at the top and bottom of the second end 32, respectively.

[0062] For example, viewed from a third direction D3, the recess 32a is rectangular. 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 be fixed or variable. For example, the depth of the recess 32a increases towards the center of the recess 32a in the second direction D2. For example, the cross-section of the recess 32a when cut along a plane extending in both the second direction D2 and the third direction D3 is arc-shaped.

[0063] In this case, the radius of curvature of the arc-shaped portion of the cross-section of the recess 32a can also be larger 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.

[0064] Figure 4 (a) is an enlarged perspective view, taken from the wearer's side (inner side), showing the first connecting part 20 connected to the temple 3 and the second connecting part 30 connected to the post head 4b, when the eyepiece 1 is worn. Figure 4 As shown in (a), with the temple 3 and the post head 4b aligned in a straight line, the recess 32a and the first side 32b (refer to) Figure 2 The pile head 4b is covered by the arc-shaped portion 22c of the first end 22 of the first connecting portion 20 and the pile head 4b in the third direction D3 (vertical direction), making it difficult to visually identify. The portion of the pile head 4b opposite to the arc-shaped portion 22c may be arc-shaped along the arc-shaped portion 22c.

[0065] Figure 4 (b) indicates that the temple 3 is from Figure 4 A perspective view of the connecting member 10 in the state of (a) where it is bent further in the opening direction of the second direction D2. (See diagram below.) Figure 4 As shown in (b), when the temple 3 is further bent in the opening direction, a portion of the recess 32a and the first side 32b protrudes from the first end 22, while the remaining portion of the first side 32b is covered by the head 4b. The bending method of the temple 3 will be described in detail later.

[0066] The second connecting portion 30 is covered by the pile head 4b and the first end portion 22. More specifically, the box-shaped portion 31b in the second connecting portion 30 (see...) Figure 3 The first side 32b and the third side 32g are covered by the head 4b. The first side 32b and the recess 32a are covered by the arc-shaped portion 22c of the head 4b and the first end 22. When the temple 3 is bent relative to the head 4b in the second direction D2 or the third direction D3, the second side 32f and the second hook portion 33 are exposed when viewed from a direction other than the inside.

[0067] As described above, when the eyepiece 1 is assembled, the recess 32a becomes difficult to visually identify. The cylindrical first end portion 22 of the first connecting portion 20 is easily visible to the naked eye, thus improving the appearance design of the eyepiece 1 and preventing foreign objects from entering the recess 32a, which is covered in the vertical direction by the arcuate portion 22c of the first end portion 22.

[0068] Refer again Figure 2 and Figure 3 The second end portion 32 has a protrusion 32c. The protrusion 32c is located, for example, at the front end portion of the second end portion 32 in the first direction D1. The protrusion 32c is formed at the corner portion 32h of the second end portion 32. The corner portion 32h is located at the corner of the first side surface 32b and extends along the third direction D3. The protrusion 32c protrudes obliquely at the corner portion 32h relative to both the first direction D1 and the second direction D2.

[0069] The second end portion 32 has, for example, a protrusion 32d. The protrusion 32d is located, for example, at the front end portion of the second end portion 32 in the first direction D1. The protrusion 32d is formed at a corner portion 32k that is different from the corner portion 32h where the protrusion 32c is provided. The protrusion 32d is arranged with the protrusion 32c, for example, along the second direction D2.

[0070] The second latching portion 33 protrudes from the second mounting portion 31. The second latching portion 33 also protrudes from the second end portion 32. For example, the second end portion 32 has an internal space for accommodating the second latching portion 33 and an opening communicating with the internal space and formed on the second side surface 32f, from which the second latching portion 33 protrudes in a first direction D1. For example, the second latching portion 33 is fixed inside the second end portion 32, and a portion of the second latching portion 33 protrudes from the second end portion 32. The second latching portion 33 is, for example, annular when viewed from the second direction D2. The second latching portion 33 may also be annular when viewed from a third direction D3, and the orientation of the second latching portion 33 is not particularly limited.

[0071] As described above, the first latching part 23 is hook-shaped, and the second latching part 33 is ring-shaped. The first latching part 23 is latched onto the second latching part 33. Alternatively, the first latching part 23 can be ring-shaped, and the second latching part 33 can be hook-shaped. The second end portion 32, for example, has a second through hole 32e. The second through hole 32e extends through 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 latching part 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 latching part 33, the second latching part 33 is fixed to the second end portion 32.

[0072] Figure 5 This is an exploded perspective view showing the connecting component 10. For example... Figure 3 and Figure 5 As shown, a portion of the first latching portion 23 is disposed inside the first mounting portion 21 (cylindrical portion 21b). The first latching portion 23 extends, for example, along a first direction D1. The first latching portion 23 has, for example, a portion 23a housed inside the first mounting portion 21, which is, for example, rod-shaped.

[0073] A portion of the second latching part 33 is disposed within the interior space of the second end 32. The second latching part 33 extends, for example, along a first direction D1. The second latching part 33 has, for example, a portion 33a received within the interior of the second end 32, which is, for example, plate-shaped.

[0074] The second latching portion 33 has, for example, a hole 33b. The hole 33b passes through a portion 33a of the second latching portion 33 in the second direction D2. The aforementioned screw (for fixing the second latching portion 33 to the second end 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 32, the second latching portion 33 is fixed to the second end 32.

[0075] 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, capable of stretching and contracting in a first direction D1. In one example, the first elastic body 41 and the second elastic body 42 are coil springs. The first elastic body 41 and the second elastic body 42 are springs with 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 repels the external force.

[0076] The first elastic body 41 is disposed inside the first connecting portion 20. For example, the first elastic body 41 is disposed on the outer periphery of the portion 23a of the first latching portion 23 that does not protrude from the first end 22. The second elastic body 42 is disposed inside the second connecting portion 30. The second elastic body 42 is arranged with the second latching 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.

[0077] The first elastic body 41 applies force to the first latching 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 latching portion 23. Therefore, the first latching portion 23 can extend and retract freely relative to the first mounting portion 21. The second elastic body 42 applies force to the second latching 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 latching portion 33. Therefore, the third latching portion 33 can extend and retract freely relative to the second mounting portion 31.

[0078] The first mounting portion 21 of the first connecting portion 20 is attached to the second mounting portion 33 via the first mounting portion 23, and the second mounting portion 31 of the second connecting portion 30 is connected to the second mounting portion 31 of the second connecting portion 30. The second end portion 32 of the second connecting portion 30 is connected to the first end portion 22 of the first connecting portion 20. Thus, the first connecting portion 20 and the second connecting portion 30 are connected to each other.

[0079] like Figure 1 and Figure 5 As shown, 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 head 4b of the post. The first latching portion 23 is retractable relative to the first mounting portion 21 via the first elastic body 41, and the second latching portion 33 is retractable relative to the second mounting portion 31 via the second elastic body 42. Furthermore, the second connecting portion 30 is connected to the first connecting portion 20 by the first latching portion 23 latching onto the second latching portion 33.

[0080] Therefore, the first mounting portion 21 installed on the temple 3 and the second mounting portion 31 installed on the head 4b can move freely relative to the first hook portion 23 and the portion hooked onto the second hook portion 33. Thus, the temple 3 can move freely up, down, left, and right relative to the head 4b, and can rotate about an imaginary axis extending along the first direction D1. That is, the extension direction of the temple 3 can be freely changed with the head 4b as a fulcrum, and the temple 3 can be freely bent relative to the head 4b.

[0081] Figure 6 This is an enlarged perspective view of the connecting component 10 in a bent state. Figure 6 This indicates that the first connecting part 20 is bent toward the second connecting part 30. Figure 1 and Figure 6 In the example shown, the temple 3 is bent in a manner that moves upward relative to the head 4b of the post.

[0082] 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 can move relative to the portion P of the first latching portion 23 that is latched to the second latching portion 33 via the first elastic body 41 and the second elastic body 42. The first connecting portion 20 can rotate relative to the second connecting portion 30 about an imaginary straight line extending along the second direction D2 and passing through the latching portion P. For example, the first connecting portion 20 can rotate approximately 90° from the first direction D1 to both sides (vertical direction) of the third direction D3.

[0083] The arc-shaped portion 22c of the first end portion 22 of the first connecting portion 20 protrudes toward the second end portion 32 of the second connecting portion 30. When the first connecting portion 20 is bent toward the second connecting portion 30, the arc-shaped portion 22c enters the recess 32a of the second end portion 32 of the second connecting portion 30. When the arc-shaped portion 22c enters the recess 32a, it enters a position closer to the inside of the second end portion 32 than the first side surface 32b of the second end portion 32. At this time, the arc-shaped portion 22c can also be engaged with 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.

[0084] Figure 7 It indicates to and Figure 6 Enlarged perspective view of the connecting component 10 under different bending directions. Figure 1 and Figure 7 In the example shown, the temple 3 is bent so that it moves relative to the head 4b from the first direction D1 to the second direction D2 (opening direction). The first connecting part 20 is rotatable relative to the second connecting part 30 about an imaginary axis that extends through the hooked part P and along the third direction D3.

[0085] For example, the first connecting portion 20 can rotate approximately 90° to each of the two sides (left and right directions) in the second direction D2. The first connecting portion 20 can rotate approximately 90° in the opening direction and the opposite direction, i.e., the closing direction. The state of rotating approximately 90° in the closing direction is the state of folding the temple 3 during normal use (the state of folding when the eyepiece 1 is folded up). When the temple 3 is bent in a manner that moves relative to the post head 4b in the second direction D2, the protrusion 32c of the second end portion 32 of the second connecting portion 30 enters the hole 22g of the first end portion 22 of the first connecting portion 20.

[0086] The first connecting portion 20 is movable relative to the second connecting portion 30 in directions inclined relative to both the second direction D2 and the third direction D3. The first connecting portion 20 is capable of rotating 360° relative to the second connecting portion 30 about an imaginary straight line extending along the first direction D1 via the hook portion P. That is, via the connecting member 10, the temple 3 is capable of rotating 360° relative to the front frame 4 about an imaginary straight line aligning the temple 3 and the front frame 4. via the connecting member 10, the rear end portion 3a of the temple 3 is capable of rotating 360° in a circular motion on an imaginary plane parallel to the plane extending along the second direction D2 and the third direction D3.

[0087] Next, the effects obtained from the eyepiece 1 and connecting member 10 of this embodiment will be described in more detail. In this eyepiece 1, the connecting member 10 includes: a first connecting portion 20 having a first mounting portion 21 and a first hook portion 23 mounted on the temple 3; and a second connecting portion 30 having a second mounting portion 31 and a second hook portion 33 mounted on the head 4b. The first mounting portion 21 and the second mounting portion 31 can move relative to the portion P of the first hook portion 23 that is hooked onto the second hook portion 33 via a first elastic body 41 and a second elastic body 42. The first end portion 22 of the first connecting portion 20 has an arcuate portion 22c. The second end portion 32 of the second connecting portion 30 has a recess 32a into which the arcuate portion 22c enters. The first connecting portion 20 and the second connecting portion 30 are connected to each other by the hooking of the first hook portion 23 and the second hook portion 33.

[0088] 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 enters the recess 32a of the second end portion 32. When the first connecting portion 20, which connects to the temple 3, is bent toward the second connecting portion 30, which connects to the head of the frame 4b, the arc-shaped portion 22c enters the recess 32a. Thus, the first connecting portion 20 is bent relative to the second connecting portion 30 with the portion of the arc-shaped portion 22c entering the recess 32a as a fulcrum. Therefore, deviation in directions other than the bending direction can be suppressed, and the bending action can be performed stably. In this embodiment, stability can be ensured when the temple 3 is bent relative to the head of the frame 4b with an imaginary axis extending along the second direction D2 as the center. Therefore, the bending action of the temple 3 relative to the head of the frame 4b can be performed stably.

[0089] In this disclosure, "arc-shaped" includes not only arcs but also shapes different from arcs. The "arc-shaped portion" can be any portion that achieves the same effect as described above, or it can be a portion with a different shape than an arc. Furthermore, even if the first connecting portion 20 and the second connecting portion 30 are made of metal, the first connecting portion 20 will not come into contact with the resin-made pile head 4b when it enters the recess 32a and bends through the arc-shaped portion 22c, thus reducing wear on the pile head 4b.

[0090] In this embodiment, the arc-shaped portion 22c can also contact the recess 32a. As described above, the cross-section of the recess 32a is arc-shaped when cut along a plane extending in the second direction D2 and the third direction D3. Therefore, compared to the case where the bottom surface of the recess 32a is flat, the contact area of ​​the arc-shaped portion 22c in the recess 32a can be increased. Therefore, when the temple 3 is bent relative to the post head 4b, the arc-shaped portion 22c can contact the surface of the recess 32a, thus stabilizing the bending.

[0091] 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 enters. The protrusion 32c and the hole 22g are not fixed to each other. By entering the hole 22g through the protrusion 32c, the first connecting portion 20 is bent relative to the second connecting portion 30 with this portion as a fulcrum, thus suppressing deviation in directions other than the bending direction and enabling stable bending operations. In this embodiment, stability can be ensured when the temple 3 is bent relative to the head 4b of the frame with an imaginary axis extending along a third direction D3 as the center. As a result, the bending operation of the temple 3 relative to the head 4b of the front frame 4 can be performed more stably.

[0092] In this embodiment, the first end 22 is formed as a cylinder with an arc-shaped portion 22c. In this case, by making the first end 22 cylindrical, the shape of the first end 22 can be simplified, and as an eyeglass 1 in which the temple 3 can be intuitively felt to rotate freely 360° relative to the head 4b of the front frame 4, the appearance design can be improved.

[0093] In this embodiment, the second connecting portion 30 is connected to the pile head 4b. The second connecting portion 30 is covered by the pile head 4b and the first end portion 22. As a result, when the eyepiece 1 is viewed from the outside, the recess 32a is difficult to visually identify and foreign objects can be prevented from entering the recess 32a.

[0094] The embodiments of the eyepiece and connecting component of this disclosure have been described above. However, the eyepiece and connecting component of this disclosure are not limited to the above-described embodiments and can be further modified within the scope of the spirit of the claims. That is, the shape, size, material, quantity, and arrangement of each part of the eyepiece and connecting component of this disclosure can be appropriately changed within the scope of the above spirit.

[0095] For example, in the above embodiment, an example was described where the first connecting part 20 is connected to the temple 3 and the second connecting part 30 is connected to the head of the post 4b. However, it is also possible to connect the first connecting part to the head of the post 4b and the second connecting part to the temple 3.

[0096] In the above embodiments, an example has been described in which the eyepiece 1 includes 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 eyepiece may also include only one of the first elastic body 41 housed in the first mounting portion 21 and the second elastic body 42 housed in the second mounting portion 31.

[0097] In the above embodiment, an example was described where the second end 32 has a protrusion 32c and the first end 22 has a hole 22g. However, it is also possible for the first end 22 to have a protrusion and the second end 32 to have a hole. In the above embodiment, a cylindrical first end 22 including an arcuate portion 22c was described. However, as long as the first end includes an arcuate portion, the shape of the first end as a whole can be other than cylindrical.

[0098] In the above embodiment, an example of the recess 32a facing both sides in the third direction D3 was described. However, the recess 32a may also face in a direction other than the third direction D3. For example, the recess 32a may also face both sides in the second direction D2.
