Description

TECHNICAL FIELD

[0001] The present application relates to eyeglasses, and particularly to the shape of the temples and the structure of the hinges. BACKGROUND

[0002] In general eyeglasses, there are various types such as full-frame type, half-frame type, two-point (rimless) type, and the like. In such general eyeglasses, a post head (frame rim) portion is provided on the outer side of the frame that mounts the left and right lenses, and further, a hinge (hinge) is provided in the post head portion. Generally, the temple (eyeglass temple) that abuts against the side portion of the head of the user (wearer) via the hinge is mounted in a manner that it can be turned inward from a prescribed spread state, and the temple can be folded.

[0003] Generally, eyeglasses are necessary for people with poor eyesight, and are used frequently in daily life. Therefore, the wearing comfort (wearing feeling) is high in priority for the user who uses the eyeglasses in terms of purchase or selection of the eyeglasses to be used. As one of the methods to improve the wearing comfort, there is adjustment of the temples. By adjusting the temples, eyeglasses that are suitable for the wearing feeling of the user can be provided. The adjustment of the temples is performed by gradually bending (warping) the temples using tools or jigs (adjustment tools) such as pliers, tweezers, and the like. At the time of adjustment, the portion of the temple that is close to the hinge or the post head portion is often bent to perform the adjustment, and by performing the adjustment as described above, eyeglasses that are suitable for the wearing comfort of the user are provided.

[0004] In Patent Document 1, the frame and the temples of the eyeglasses are composed of a super-elastic alloy, and are formed in a cylindrical shape in which the inside of the temple is hollow. Further, an aluminum alloy that is processed in a cylindrical shape is inserted into the inside of the temple. Thereby, compared with the weight of the conventional eyeglasses, the weight is light and it is difficult to bend, and thus the wearing comfort is improved.

[0006] PATENT DOCUMENTS

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 2003-43427 SUMMARY

[0008] (PROBLEMS TO BE SOLVED BY THE INVENTION)

[0009] However, in Patent Document 1, as described above, the temple that is difficult to break, i.e., has high rigidity and is difficult to plastically deform, compared with the conventional eyeglasses. Therefore, adjustment of the temple and fine adjustment of the temple for left and right wearing comfort become difficult. With regard to the adjustment of the temple, in order to perform adjustment suitable for the user by repeatedly performing fine adjustment using the adjustment tools such as pliers, it is important that the material that forms the temple, or the cross-sectional shape that easily grasps (easily holds) the tools for adjustment by the pliers, is formed.

[0010] In addition, the temple of the eyeglasses of Patent Literature 1 is made into a circular shape in cross section in addition to the configuration for not being easily bent. Therefore, when adjustment is performed using an instrument used in adjustment with pliers or the like, adjustment is difficult to perform because of easy slippage or difficulty in gripping. Also, in Patent Literature 1, the configuration is such that the stud head portion is integrated with the hinge, and as described above, in order to adjust the temple which is high in rigidity and difficult to plastically deform, if a strong force is applied, there is a problem that the hinge is damaged.

[0011] Therefore, an object of the present application is to provide eyeglasses which are easy to adjust the temple, for example, and are excellent in wearing comfort.

[0012] (Technical Solution for Solving the Problem)

[0013] In order to achieve the above object, eyeglasses according to one aspect of the present application are eyeglasses provided with a lens and a rim into which the lens is inserted, characterized by having: a hinge fixed to the back surface of a stud head portion formed at one end of the rim; and a temple installed to the hinge in a rotatable manner, the hinge being provided with a joint portion for joining one end of the temple, the joint portion being formed at a position inside the edge of the stud head portion, the temple being formed so as to extend from the one end of the temple which is joined to the joint portion toward the other end, and being bent in the vicinity of the edge of the stud head portion in such a manner that the angle between the temple and the stud head portion becomes a prescribed angle or more.

[0014] (EFFECT OF THE INVENTION)

[0015] According to the present application, it is possible to provide eyeglasses which are easy to adjust the temple and are excellent in wearing feeling, for example. BRIEF DESCRIPTION OF DRAWINGS

[0024] An eyeglass involved in one embodiment of the present application is described with reference to the drawings. Note that the following embodiments are preferred specific examples of the eyeglasses of the present application, and sometimes have various limitations that are preferred in terms of surgery, but the technical scope of the present application is not limited to these embodiments as long as the description of the present application is not particularly limited. In addition, the components in the following embodiments can be appropriately replaced with existing components or the like, and various modifications including combinations with other existing components can be made. Therefore, the content of the invention described in the claims is not limited to the description of the following embodiments.

[0025] (First Embodiment)

[0026] First, with reference to Figure 1 and Figure 2 the eyeglasses 1 involved in the first embodiment are described. Figure 1 is a front view and a side view of the eyeglasses 1 in the first embodiment. Figure 2 is a plan view of the eyeglasses 1 in the first embodiment. In addition, in the first embodiment, the left-right direction when the eyeglasses 1 are viewed from the front direction is set as the X direction, the up-down direction is set as the Z direction, and the near-far direction and the longitudinal direction are set as the Y direction. Figure 1

[0027] On the eyeglasses (frame) 1, as shown in Figure 1 , a rim 3 in which the lenses 2 are inserted and fixed, a nose pad 4 that abuts against the nose when the eyeglasses 1 are worn, and a mounting portion (temple arm) 4a that can mount each nose pad 4 to the rim 3 are provided.

[0028] ​Furthermore, the lens rings 3 are connected via the nose bridge 5. That is, the lenses 2 are inserted into and fixed to the left and right lens rings 3 connected via the nose bridge 5. This connection is, for example, by brazing. Alternatively, the lens rings 3 may not be connected via the nose bridge 5, and the lens rings 3 and the nose bridge 5 may be formed as one piece. A post head 6 is provided at one end of each lens ring 3, and a hinge 7 is installed at each post head 6. A temple 8 is connected to each hinge 7. The temple 8 is installed to the hinge 7 in a foldable manner. That is, one end of the temple 8 is connected (attached) to the hinge 7 in a manner that allows rotation relative to the hinge 7. In addition, in the first embodiment, the post head 6 and the lens ring 3 are formed as one piece. However, it is not limited to this, and may be formed separately from the lens ring 3, for example, detachably. In addition, the entire front frame of the glasses 1, including the lens rings 3, nose pads 4, mounting part 4a, and nose bridge 5, is also referred to as the front.

[0029] Furthermore, a connecting part (not shown) with a through hole is formed at one end of the temple 8. This connecting part is for use with the part described later. Figure 3 The hinge 7 shown above is connected (for mounting) to the connecting portion 7a. Additionally, the other end of the temple 8 is formed as an ear loop that bends downward and engages with the wearer's ear. In the first embodiment, a temple tip (front unit) 9 is mounted on a portion of the temple 8. In the first embodiment, the temple tip 9 is configured to be detachable from the temple 8, but it is not limited to this and may also be integrally formed with the temple 8.

[0030] The lens ring 3 or temple 8 can be made of metals such as titanium alloy (e.g., β-titanium alloy), stainless steel, aluminum alloy, or resin (e.g., CP, acetate), or other materials. The nose pad 4 can be made of shell, resin, metal (e.g., titanium alloy, stainless steel), or other materials. The mounting part 4a, if made of metal, can be mounted to the lens ring 3 by welding (fusion, pressing, brazing) or bonding, or it can be fixed by threaded fastening and integrally formed with the lens ring 3. Alternatively, it can be mounted by other methods. Furthermore, the lens ring 3 is not limited to metal; it can also be made of resin or other materials.

[0031] For example, when both the lens ring 3 and the mounting part 4a are metal, they can be integrally formed by welding (brazing), threading, bonding, or embedding. Alternatively, when both the lens ring 3 and the mounting part 4a are metal, a base (metal or resin, etc.) for mounting the mounting part 4a can be provided on the resin of the lens ring 3 (e.g., assembly), and mounting can be performed by welding, bonding, etc. Furthermore, when both the lens ring 3 and the mounting part 4a are resin, mounting can also be performed by welding or integral forming. Other methods are also possible for mounting.

[0032] Next, refer to Figure 3 and Figure 4 The structure of the hinge 7 and the shape of the temple 8 of the eyeglasses 1 according to the first embodiment will be described. Figure 3 This is an enlarged view of the area surrounding the hinge 7 according to the first embodiment. Figure 4 This is a diagram showing the hinge 7 and the fixing plate 11 according to the first embodiment. Figure 4 Figure (A) shows the hinge 7 in the first embodiment. Figure 4 Figure (B) shows the fixing plate 11 in the first embodiment. The hinge 7 in the first embodiment includes a connecting portion 7a for connecting to a connector (not shown) formed at one end of the temple 8. Furthermore, it includes a flat portion 7b formed extending orthogonally from one end of the connecting portion 7a. Thus, the hinge 7 in the first embodiment is formed in an "L" shape. Moreover, as... Figure 4 As shown, the hinge 7 has two through holes 7c in the flat portion 7b. Furthermore, the hinge 7 can be made of metals such as titanium alloy (e.g., β-titanium alloy), stainless steel, or aluminum alloy, resin (e.g., CP, ester acetate), or other materials.

[0033] Connecting portions 7a are respectively formed with connecting parts 7d and 7e, each having a through hole. Furthermore, a groove is formed between connecting parts 7d and 7e, and the connecting portion 7a is configured in a "コ" shape. A connector (not shown) formed at one end of the temple 8 is inserted into this groove (the space between connecting parts 7d and 7e), and connected using screws (not shown) for connection. By using connecting screws for connection, the temple 8 can be rotatably mounted to the hinge 7. In the first embodiment, as described above, the connecting portion 7a has two connecting parts (connecting parts 7d and 7e) configured in a "コ" shape, but this is not limited to this; one or three connecting parts may also be formed. Furthermore, three or more connecting parts may be formed.

[0034] by Figure 3 For example, the temple 8 can be folded in the -X direction, i.e., the inward direction, using the connecting screw as a fulcrum. Furthermore, based on the structure of the hinge 7 and the shape of the temple 8 in the first embodiment, the temple 8 can be rotated (twisted) around the connecting screw at a predetermined angle, not limited to the inward direction, but also in the outward direction (+X direction). Thus, the temple 8 in the first embodiment can rotate more than 90 degrees around the connecting screw. Additionally, an adjustment mechanism can be provided in the connecting portion 7a, etc., to define a predetermined rotation range, allowing adjustment of the temple 8's rotation range. Furthermore, the rotation range of the temple 8 can be adjusted by providing an adjustment protrusion or stop mechanism in the hinge 7, etc. Additionally, in relation to...Figure 3 The hinge 7 shown in the pair of hinges 7 Figure 3 The hinge 7 shown in the pair of hinges 7

[0035] In the first embodiment, the connecting screw that connects the temple 8 and the hinge 7 is inserted from the lower side (-Z direction side) of the connecting portion 7a of the hinge 7, and the connecting members of the hinge 7 and the temple 8 are screwed to be connected. A groove having a prescribed depth is formed on the connecting member portion 7d of the connecting member on the upper surface side. The shape of the groove formed can be any shape. Further, by embedding and fixing a plate formed in a manner that conforms to the shape of the groove formed on the connecting member portion 7d, it is difficult to visually recognize the connecting screw. Thereby, when visually recognizing the glasses 1, the aesthetics of the glasses 1, particularly the hinge 7 periphery, is improved.

[0036] In addition, for example Figure 3 The connecting portion 7a shown can also be formed by further extending the connecting portion 7a with respect to the -Y direction (depth direction). Thereby, the rotation range of the temple 8 can be further expanded.

[0037] The flat portion 7b is formed to have a prescribed thickness. Further, the two hole portions 7c formed on the flat portion 7b are formed as through holes as described above. The fixing plate 11 is composed of a plate portion 11a and two protrusion portions 11b formed in a cylindrical shape. The two protrusion portions 11b are respectively fixed to the plate portion 11a by joining. In addition, regarding the shape of the fixing plate 11, Figure 4 The shape shown in (B) is one example, and the shape of the fixing plate 11 is not particularly limited. In addition, as the shape of the fixing plate 11, for example, it can be Figure 4 The substantially rectangular shape shown in (B) can also be chamfered (R-processed) at each corner portion. In addition, the shape of each fixing plate disposed at each stud head portion 6 can also be made the same shape. For example, one end or the other end of one fixing plate 11 can be processed into a circular or polygonal shape, and the other end or one end of the other fixing plate 11 can be processed into a circular or polygonal shape. Or, it can be made into a shape other than this.

[0038] Next, the fixing method of the hinge 7 to the stud head portion 6 will be described. As the fixing of the hinge 7 to the stud head portion 6, first, the flat portion 7b of the hinge 7 is disposed on the back surface of the stud head portion 6. At the time of disposition, the connecting portion 7a of the hinge 7 is disposed more inward than the flat portion 7b (with the connecting portion 7a of the hinge 7 being disposed on the -X direction side and the flat portion 7b being disposed on the +X direction side in the drawing). Further, the two protrusion portions 11b of the fixing plate 11 are disposed on the two hole portions 7c of the flat portion 7b. Figure 3For example, the hinge 7, the joint portion of the hinge 7 and the temple leg 8, and a portion of the temple leg 8 are configured inward of the edge of the peg head 6 in a manner that is configured in a direction (for example, the -X direction) that is inward of the edge of the peg head 6. Thus, the hinge 7, the joint portion of the hinge 7 and the temple leg 8, and a portion of the temple leg 8 are configured inward of the edge of the peg head 6 in a manner that is configured in a direction (for example, the -X direction) that is inward of the edge of the peg head 6. In addition, in the first embodiment, the through holes of the peg head 6 are formed in two portions on the left and right. Also, when the flat portion 7b of the hinge 7 is disposed on the back surface of the peg head 6, the flat portion 7b is disposed at a position that is in register with each of the hole portions. In addition, the plurality of through holes formed in the peg head 6 can be formed as loose holes that are longer in the X direction or the Z direction, and in the case of being formed as loose holes, the through holes can be formed in one portion on the left and right.

[0039] Next, the two protruding portions 1 lb of the fixing plate 11 are inserted into the two hole portions 7c formed in the hinge 7 via the two through holes formed in the peg head 6, respectively, to dispose the fixing plate 11 on the surface of the peg head 6. Thereafter, the portions protruding from the surface of the two hole portions 7c (the protruding portions of the two protruding portions 1 lb) are flattened using a tool or a machine tool, or the like. Thus, as shown in FIG. 8, for example, the flattened portions of the two protruding portions 1 lb form fixing portions 10 having a diameter that is larger than the hole diameter of the two hole portions 7c. By forming the fixing portions 10, the fixing plate 11 does not fall off from the peg head 6, and the hinge 7 can be fixed (rivet-fixed) to the peg head 6. Figure 3

[0040] Thus, in the fixing of the hinge 7 in the first embodiment, since a screw, a nut, or the like is not used, the aesthetics of the glasses 1, particularly the peg head 6 and the periphery of the hinge 7, are improved when the glasses 1 are viewed from the front direction (from the +Y direction to the -Y direction side) or the side direction. In addition, after the fixing plate 11 is fixed to the peg head 6, the fixing plate 11 functions as a decorative portion (decorative member). In addition, the fixing plate 11 is preferably metal, but is not limited thereto, and can be formed of a material other than metal, such as resin, wood, or the like.

[0041] In addition, instead of flattening the portions of the two protruding portions 1 lb that protrude from the surface of the two hole portions 7c, a fixing cap (fixing member) can be fitted over and fixed to the portions of the two protruding portions 1 lb that protrude from the surface of the two hole portions 7c. In this case, the fixing cap functions in the same manner as the fixing portions 10 described above. Thus, the hinge 7 can be fixed to the peg head 6 without flattening the two protruding portions 1 lb. In addition, the two protruding portions 1 lb, which are cylindrical, can be thread-cut machined, respectively. In this case, the fixing cap described above can be used as a nut. In this case, the nut functions in the same manner as the fixing portions 10 described above. In the fixing, the protruding portions 1 lb are screwed into the nut, respectively, to be fixed.

[0042] ​Further, in the fixed plate 11, instead of the two protruding portions 1 lb, a hole portion of a screw thread cut to a prescribed depth can be formed at the positions of the two protruding portions 1 lb. The fixing method of the hinge 7 in this case will be described below. First, with respect to the two hole portions 7c of the flat portion 7b, a screw for fixing is inserted from the -Y direction toward the +Y direction, and by screwing into the screw hole of the fixed plate 11 disposed on the opposite side from the stud head portion 6 with which the flat portion 7b is in contact, the hinge 7 can be fixed to the stud head portion 6. Also, as with the above, the stud head portion 6 is provided with a through hole for allowing the screw to be inserted therethrough. The diameter of this through hole is preferably formed to be larger than the diameter of the screw for fixing. Also, the through hole formed in the stud head portion 6 can be formed as a screw hole of the same diameter as the screw hole formed in the fixed plate 11.

[0043] Also, in the case where a screw is used in the fixing of the hinge 7 as described above, the shape of the screw for fixing is not particularly limited, and for example, a case where a countersunk head screw having a flat upper surface and a conical seat surface is used is assumed. In this case, it is preferable to perform counterbore machining on the two hole portions 7c of the flat portion 7b on the side into which the countersunk head screw is inserted. Thereby, it is possible to suppress the upper surface of the countersunk head screw from protruding from the upper surface of the flat portion 7b or to suppress the amount of protrusion of the upper surface of the countersunk head screw. Also, since the flat portion 7b is inserted into the upper surface of the countersunk head screw, there is an effect that the upper surface of the countersunk head screw does not come into contact with the temple leg 8 when the temple leg 8 is turned, and it is possible to expand the turning range with respect to the outside direction.

[0044] In the first embodiment, the protruding portion 1 lb of the fixed plate 11 is provided as two, but is not limited thereto, and can be provided as one, or can be provided as three or more. The same applies to the through hole formed in the stud head portion 6. Also, the stud head portion 6 and the flat portion 7b can be fixed by brazing. In this case, the fixed plate 11 is also fixed to the stud head portion 6 by brazing.

[0045] The temple leg 8 in the first embodiment is formed so as to extend from one end side of the temple leg 8 connected to the connecting portion 7a toward the other end side, and to bend by a prescribed angle or more (to bend in a prescribed direction) toward the inside direction (the -X direction, for example) in the vicinity of the edge of the stud head portion. That is, processing is performed so as to bend a portion of the temple leg 8 by a prescribed angle or more. The position (point) at which the prescribed angle or more is bent is one on each of the left and right temple legs 8. Also, as shown in the drawing, the temple leg 8 of the first embodiment is formed so as to gradually bend from the above-described bent position toward the other end toward the inside direction (the -X direction, for example). Figure 3 Figure 2 However, it is not limited thereto, and can be formed so as not to bend from the above-described bent position toward the other end. Figure 3

[0046] ​​Further, as the above-described prescribed angle, in Embodiment 1, the angle between the stud head 6 and the temple 8 is made to be 90 degrees or more. That is, as shown in Figure 3 the temple 8 is bent so that the angle θ between the imaginary vector line VI in the stud head 6 and the imaginary vector line V2 in the temple 8 is 90 degrees or more. By making the angle θ 90 degrees or more, the size of a general (average) face of various users can be dealt with. The angle θ is preferably an angle in which there is no sense of incongruity in terms of wearing comfort when a general user wears the eyeglasses 1. As 90 degrees or more, for example, 90 degrees or more and less than 130 degrees or the like can be considered. Further, the angle θ is not limited to 90 degrees or more, and can be less than 90 degrees. This is because, in the case of less than 90 degrees, a user of a size smaller than the size of a general face or a case in which the eyeglasses 1 are large relative to the size of a face can be dealt with. As less than 90 degrees, for example, less than 90 degrees and 70 degrees or more or the like can be considered.

[0047] In the first embodiment, the bending point (kink point) is substantially aligned with the edge of the stud head 6. Further, it is preferable that the bending point be formed in a direction orthogonal to the edge of the stud head 6, and it is more preferable that the bending point be formed in a direction outside a prescribed distance in the direction orthogonal to the edge of the stud head 6. Further, it is not limited to the outside direction, and the bending point can be formed in a direction inside the prescribed distance from the edge of the stud head 6. By substantially aligning the bending point with the edge of the stud head 6, in the case of being observed from the front direction, it is visually recognized as the eyeglasses in which the stud head 6 is connected to the temple 8 as a hinge, and there is no loss of beauty. Further, the bend R (radius of curvature) when the temple 8 is bent is not particularly limited, but in the first embodiment, the bend R, that is, the radius of curvature is increased. By increasing the radius of curvature, it is difficult to recognize the bending point when the stud head 6 and the temple 8 are visually recognized, and there is no loss of beauty.

[0048] Figure 5 is a view illustrating a case in which the temple is adjusted. Figure 5 (A) in FIG. is a view illustrating a case in which the temple 8 is adjusted in the first embodiment. Figure 5 (B) in FIG. is a view illustrating a case in which the temple in the eyeglasses of the related art is adjusted.

[0049] In the eyeglasses of the related art, as shown in Figure 5 (B) in FIG., the adjuster adjusts the angle at which the temple is bent using the adjustment tool 100. Also, as Figure 5In typical eyeglasses as shown in (B), the temples are mostly adjusted near the hinge or the head of the frame (more preferably near the front). This is because by adjusting the position near the hinge or the head of the frame (or the front), the overall angle of the temples can be adjusted more easily, and even minor adjustments can be made more easily thereafter. Furthermore, the adjustment tool 100 is a tool or clamp capable of holding an object, such as pliers or tweezers.

[0050] According to the shape of the temple 8 and the structure of the hinge 7 in the first embodiment, the hinge 7 is disposed on the back side of the head 6, and the connecting portion 7a connecting one end of the temple 8 is also disposed on the back side of the head 6 and in the direction inward from the edge of the head 6. Therefore, the end of the temple 8 connected to the hinge 7 is positioned in the direction inward from the edge of the head 6 and closer to the front. Thus, in the first embodiment, as Figure 5 As shown in (A), the temple 8, which is located near the front, can be adjusted, thus making it easier to adjust and fine-tune the temple 8 compared to existing eyeglasses.

[0051] Furthermore, in cases such as Figure 5 In the case of typical eyeglasses shown in (B), the position for adjustment by the adjusting device 100 is limited. However, according to the shape of the temple 8 and the construction of the hinge 7 in the first embodiment, one end of the temple 8 connected to the hinge 7 is, for example, as shown in (B). Figure 3 The temple is configured as shown to have a predetermined gap (area) with the flat portion 7b of the hinge 7 and the post 6. Therefore, the temple can be adjusted to more positions using the adjusting device 100 than in the prior art, and can also be clamped near the connection between the hinge 7 and the temple 8. Furthermore, the temple 8 can be clamped regardless of the orientation of the adjusting device 100, such as its clamping position, and adjustments can be made in this state. Thus, even if the connection portion 7a of the hinge 7 and one end periphery of the temple 8 are located in a direction closer to the edge of the post head 6, adjustments and fine-tuning of the temple 8 based on the adjusting device 100 can be easily performed. Therefore, eyeglasses 1 with excellent wearing comfort can be provided to the user.

[0052] Furthermore, according to the temple 8 of the first embodiment, a portion (around the bending point) of the (bent) temple 8, which has undergone bending processing as described above, can be adjusted using the adjusting device 100, thus further suppressing the number of adjustments (bending). Therefore, even if it is made of a metal system, for example, that has the characteristics of breaking or damaging the temple 8 due to repeated fatigue (metal fatigue), the number of adjustments can be suppressed as described above, thus also suppressing problems caused by metal fatigue.

[0053] Further, for example, in a case where the cross-sectional shape of the temple of the eyeglasses in the related art is a substantially quadrangular shape or a circular shape, adjustment of the temple using the adjustment tool 100 is described below. In this case, the temple cannot be well gripped or held by the adjustment tool 100, and thus a phenomenon can occur in which the temple is bent in a direction different from an intended direction or is not bent in a desired direction even if the temple is well gripped or held. Therefore, there is a problem in that adjustment or fine adjustment is difficult. However, according to the temple 8 of the first embodiment, since the cross-sectional shape of a portion of the temple 8 is an octagonal shape, gripping based on the adjustment tool 100 can be easily performed, and the number of portions in which gripping is easily performed can be increased. Hereinafter, the cross-sectional shape of the temple 8 of the first embodiment is described with reference to FIGS. 13A to 13C. Figure 4 、 Figure 6 The cross-sectional shape of the temple 8 of the first embodiment is described.

[0054] Figure 6 is a view illustrating the cross-sectional shape of the temple 8 in the first embodiment. Figure 6 (A) in FIG. 13A is a view of the A-A' cross section in Figure 2 FIG. 13B. (B) in FIG. 13A is a view of the B-B' cross section in Figure 6 FIG. 13B. (C) in FIG. 13A is a view of the C-C' cross section in Figure 2 FIG. 13B. In addition, the A-A' cross section is illustrated with respect to one temple 8 for the sake of simplicity of description, but the cross-sectional shape is the same as the cross-sectional shape described below with respect to the other temple 8.

[0055] Figure 6 In the temple 8 of the first embodiment, as illustrated in Figure 2 FIG. 13A, the cross-sectional shape is constituted by three cross-sectional shapes. As a first cross-sectional shape, there is an octagonal cross-sectional shape illustrated in (A) in FIG. 13A. This cross-sectional shape is formed to a position that exceeds the above-described bending point by a predetermined distance from one end of the temple 8 toward the other end. Further, the range (adjustment range) in which the portion of the temple 8 that becomes this octagonal cross-sectional shape is preferable in a case where adjustment of the temple 8 is performed using the adjustment tool 100. In addition, it is preferable to perform processing (R processing) in which each corner of the octagonal shape is rounded, but it is also possible not to perform the processing in which each corner is rounded. In this way, by setting the first cross-sectional shape that is a range in which adjustment of the temple 8 is performed to an octagonal shape, as described above, the number of gripping positions in a straight line direction by the adjustment tool 100 is increased, and gripping can be easily performed. Furthermore, by the number of portions in which gripping is easily performed being increased, gripping can be performed from a plurality of directions, and thus adjustment or fine adjustment can also be easily performed. Thus, it is possible to provide the user with eyeglasses 1 that are excellent in wearing comfort.

[0056] Figure 6 As a second cross-sectional shape, an octagonal cross-sectional shape is formed Figure 6 in which the corners are rounded. This cross-sectional shape is formed to a position that exceeds the above-described bending point by a predetermined distance from one end of the temple 8 toward the other end. Further, the range (adjustment range) in which the portion of the temple 8 that becomes this cross-sectional shape is preferable in a case where adjustment of the temple 8 is performed using the adjustment tool 100. In addition, it is preferable to perform processing (R processing) in which each corner of the octagonal shape is rounded, but it is also possible not to perform the processing in which each corner is rounded. In this way, by setting the second cross-sectional shape that is a range in which adjustment of the temple 8 is performed to an octagonal shape in which the corners are rounded, as described above, the number of gripping positions in a straight line direction by the adjustment tool 100 is increased, and gripping can be easily performed. Furthermore, by the number of portions in which gripping is easily performed being increased, gripping can be performed from a plurality of directions, and thus adjustment or fine adjustment can also be easily performed. Thus, it is possible to provide the user with eyeglasses 1 that are excellent in wearing comfort.

[0057] As a third cross-sectional shape, a circular cross-sectional shape is formedFigure 6 The second cross-sectional shape is gradually changed from the end of the above-described octagonal shape cross-sectional shape toward the other end of the temple 8 to an elliptical shape. The second cross-sectional shape is formed at a position that has advanced a prescribed distance from the end of the first cross-sectional shape toward the other end of the temple 8. Specifically, it is at a position that is Figure 1 In the side view illustrated in (B), a portion of the temple 8 is widened in the Z direction. In this way, by making the second cross-sectional shape of the temple 8 an elliptical shape, the bending stress is increased, particularly the bending stress in the longitudinal direction (Z direction). Note that as this elliptical shape, it can be a general elliptical shape, or it can be a shape that has been processed so that the corners of the generally rectangular shape are rounded.

[0058] As the third cross-sectional shape, a circular shape is formed Figure 6 In (C), a circular shape is illustrated. The third cross-sectional shape is a shape that is gradually changed from the end of the above-described elliptical shape second cross-sectional shape toward the other end of the temple 8 to a circular shape. The third cross-sectional shape is formed from the end of the second cross-sectional shape to the other end of the temple 8. In this way, by making the third cross-sectional shape of the temple 8 a circular shape, for example, in order to shorten the overall length of the temple 8, when the foot cover 9 is removed and a portion of the third cross-sectional shape is cut, the foot cover 9 or a foot cover that is different from the foot cover 9 can be inserted into the temple 8 again. This is because, considering the workability, efficiency, and the like at the time of manufacturing or processing, for example, the hole portion for insertion into a general temple 8 is often a circular shape. Note that as the third cross-sectional shape, it can not be a perfect circle or a shape close to a perfect circle, or it can be a generally circular shape that takes into account processing errors (tolerances) and the like.

[0059] As described above, in the first embodiment, the temple 8 is formed so that the cross-sectional shape is sequentially an octagonal shape, an elliptical shape, and a circular shape from one end toward the other end. That is, it is formed so that the cross-sectional shape changes from an octagonal shape to a different shape as it progresses from one end of the temple 8 toward the other end. However, it is not limited to this, and for example, it can be sequentially formed from an octagonal shape from one end of the temple 8, and then formed only by an elliptical shape or a circular shape. In addition, it can be formed so that the cross-sectional shape of the temple 8 is only an octagonal shape. In addition, it can be formed so that the cross-sectional shape is sequentially an octagonal shape, an elliptical shape, and an octagonal shape from one end toward the other end, or it can be formed so that the cross-sectional shape is sequentially an octagonal shape, a circular shape, and an octagonal shape.

[0060] As described above, according to the shape of the temple 8 of the eyeglasses 1 of the first embodiment and the configuration of the hinge 7, the adjustment of the temple 8 can be easily performed, and the eyeglasses 1 that are excellent in terms of the feeling of wearing can be provided to the user.

[0061] (Second Embodiment)

[0062] Next, the following describes the eyeglasses 1 according to the second embodiment with reference to Figure 7 The eyeglasses 1 according to the second embodiment will be described below. Figure 7 is an enlarged view of the vicinity of the hinge 7 of the eyeglasses 1 according to the second embodiment. In addition, the eyeglasses 1 according to the second embodiment are the same structure as the eyeglasses 1 according to the first embodiment except that the standing portion 7f is formed at a part of the hinge 7, and thus the description of the overlapping explanation is omitted.

[0063] The hinge 7 of the eyeglasses 1 according to the second embodiment has the linking portion 7a at one end of the flat portion 7b, and further has the standing portion 7f at the other end of the flat portion 7b. The standing portion 7f is also a "コ" shape like the linking portion 7a, and is formed in a manner to constitute a groove like the linking portion 7a. The groove of the standing portion 7f is configured so that a part of the temple 8 is inserted into the groove when the one end of the temple 8 is linked with the linking portion 7a.

[0064] In addition, the diameter of the groove can be made slightly larger than the diameter of the temple 8 so that the temple 8 is not fitted without a gap, that is, is formed with a certain amount of play. By forming the standing portion 7f, the fixing portion of the temple 8 is constituted. Thereby, the force or impact generated at the temple 8 or the hinge 7 in the case where an unexpected force is applied to the temple 8 or in the case where the eyeglasses 1 fall down can be reduced by the standing portion 7f. Also, since a part of the temple 8 can be inserted into the groove of the standing portion 7f, the sway of the temple 8 or the like can also be reduced. In addition, by providing the standing portion 7f, the rotation range of the temple 8 can also be limited.

[0065] In addition, the groove in the standing portion 7f can also be formed up to the upper surface of the flat portion 7b. Thereby, like the first embodiment, the rotation range of the temple 8 can be expanded.

[0066] With the eyeglasses 1 according to the second embodiment, by forming the standing portion 7f at the hinge 7, the force or impact generated at the temple 8 or the hinge 7 can be reduced. Further, like the first embodiment, the adjustment of the temple 8 can be easily performed, and the eyeglasses 1 that provide an excellent wearing feeling to the user can be provided.

[0067] (Third Embodiment)

[0068] Next, the following describes the eyeglasses 1 according to the third embodiment with reference to Figure 8 The eyeglasses 1 according to the third embodiment will be described below. Figure 8 is a plan view of the eyeglasses 1 according to the third embodiment. In addition, the eyeglasses 1 according to the third embodiment are the same as the eyeglasses 1 according to the first embodiment except that the counterweight portion is constituted, and thus the description of the overlapping explanation is omitted.

[0069] In the third embodiment, a counterweight (weighting part) 12 is formed on the temple cover 9, and the temple cover is attached to a part of the temple 8 of the eyeglasses 1. The counterweight 12 is formed of a material with a higher specific gravity than the material used for the eyeglasses 1 or the temple 8. Tungsten is used in the third embodiment, but it is not limited to this; for example, raw materials such as iron, copper, lead, and gold can also be used. Furthermore, any of the general structural materials such as other metals, alloys, ceramics, composite materials, and stone can also be used.

[0070] One end of the temple cover 9 is on the side of the temple 8 (with) Figure 8 For example, in the case of the -Y direction side, the counterweight 12 is formed at the other end. The counterweight 12 is inserted into a hole (not shown) formed at the other end of the foot sleeve 9 and then fixed. In the third embodiment, the counterweight 12 is formed in a cylindrical shape, but it is not limited to this and can be other shapes. In addition, the method of fixing the counterweight 12 to the hole is not particularly limited. For example, the diameter of the counterweight 12 can be formed to gradually increase from one end to the other end and inserted into the hole for a predetermined distance. In addition, an external thread can be formed on the counterweight 12 and an internal thread can be formed on the hole so that the counterweight 12 and the hole can be screwed together. Moreover, it can also be fixed by screwing them together separately.

[0071] By incorporating the weight 12 into the temple tips 9 of the glasses 1, the center of gravity can be positioned at the other end of the temple tips 9. This prevents the glasses 1 from slipping towards the ground due to certain movements. Consequently, glasses 1 can be provided with excellent wearing comfort. Furthermore, the length or size of the weight 12 can be determined by the material of the glasses 1. Moreover, the length of the weight 12 can be adjusted to provide glasses 1 that suit the wearing comfort of each user.

[0072] As a weight adjustment mechanism for the counterweight 12, the weight of the counterweight 12 can also be adjusted by allowing it to be removed (installed / removed). For example, multiple components with a predetermined diameter and hollow shape for the counterweight 12 can be prepared separately, and the weight can be adjusted by replacing them. Alternatively, the cylindrical counterweight 12 can be divided into multiple parts at predetermined intervals, and the weight can be adjusted by adjusting the number of parts inserted into the holes formed in the temple sleeve 9. In this case, the raw materials of the divided counterweight 12 can also be different; the counterweight 12 can be formed from various materials as described above, and the counterweight 12 of each material can be divided as described above and combined to adjust the weight. Furthermore, by disassembling (installing / removing) the counterweight 12 as described above, for example, the material currently used (e.g., tungsten) can be changed to a different material (e.g., lead). Thus, the user can choose the weight, providing glasses 1 with excellent wearing comfort suitable for the user.

[0073] In the third embodiment, the center of gravity of the eyeglasses 1 is positioned at the other end of the leg 9 by providing the counterweight 12 at the other end of the leg 9 of the eyeglasses 1. Thus, the eyeglasses 1 can be prevented from sliding down toward the ground. Further, as in the first embodiment, the adjustment of the temple 8 can be easily performed, and the eyeglasses 1 having an excellent wearing feeling can be provided to the user.

[0074] In addition, the eyeglasses 1 of the third embodiment and the second embodiment can be combined. In the above-described embodiments, the shape, the structure, the configuration, and the like of each component or part (for example, the stud head 6, the hinge 7, the temple 8, and the like) on one side (for example, the right side in the drawing) of the eyeglasses 1 are described for the sake of simplicity of the description. In this case, each component or part on the other side (the side opposite to the above-described one side, for example, the left side in the drawing) is omitted from the description, and is configured to be the same as (identical to) the one side in terms of the content including the shape and the structure. In addition, as illustrated in the drawing, the arrangement position and the like of each component or part on the other side are configured to be opposite to those on the one side. Figure 2 Figure 2 Figure 2

[0075] In addition, the other end of the temple 8 in each of the above-described embodiments can be formed in a straight line direction without being bent downward. In addition, in each of the above-described embodiments, a part of the cross-sectional shape of the temple 8 is described as an octagonal shape, but is not limited thereto, and can be a hexagonal shape, a decagonal shape, or a dodecagonal shape, or the like. In addition, in each of the above-described embodiments, the number of positions (bending points) at which the temple 8 is bent is one for each of the left and right temples 8, but is not limited thereto, and can be two or more for each of the left and right temples 8.

[0076] The above-described preferred embodiments of the present application have been described, but the present application is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist thereof.
