Description

  The present invention relates to a spectacle mounting device that prevents the eyeglass frame from slipping off, and prevents hair from being entangled when the spectacle frame is detached from a wearer while the spectacle frame is attached to the spectacle frame, and the spectacle mounting The present invention relates to a spectacle frame set including a tool and a spectacle frame.

  A spectacle mounting tool as described above is disclosed in Patent Document 1. As shown in FIG. 8, the eyeglass fixture 100 described in Patent Document 1 includes a clip portion 101, an ear contact portion 103, and an entanglement preventing member 106. The clip part 101 is detachably attached to the rear part of the temple 201 of the spectacle frame 200. The ear contact portion 103 is swingably attached to the clip portion 101 via the shaft member 102, and can contact the back side of the wearer's ear. The entanglement preventing member 106 has flexibility, one end is connected to the front end portion 104 of the ear contact portion 103, and the other end is connected to the predetermined portion 203 ahead of the portion 202 where the clip portion 101 of the temple 201 is attached. It is detachably attached by the clip part 105 or the like. As shown by the arrow A in FIG. 9, the clip portions 101 and 105 of the spectacle attachment device 100 are such that when the front end portion 104 of the ear contact portion 103 is pressed against the temple 201 side, the entanglement preventing member 106 is along the temple 201. The ear contact portion 103 is attached to a portion of the temple 201 such that the ear contact portion 103 comes into contact with the back side of the ear.

  The spectacle frame 200 to which the spectacle fixture 100 is attached is mounted by putting the ear contact portion 103 of the spectacle mount 100 on the ear and pressing the front end portion 104 of the ear contact portion 103 toward the temple 201 with the ear. Can do. When the front end portion 104 of the ear contact portion 103 is pressed against the temple 201 side, the entanglement preventing member 106 follows the temple 201 and the ear contact portion 103 comes into contact with the back side of the ear. Since the entanglement preventing member 106 is along the temple 201, the spectacle frame 200 can be mounted without a sense of incongruity even when the spectacle mount 100 is mounted. Further, the ear contact portion 103 is firmly held by the ear by being in a posture in which the ear contact portion 103 is in contact with the back side of the ear.

  The spectacle mounting tool 100 can prevent the spectacle frame 200 from falling off as follows. The spectacle frame 200 to which the spectacle mounting tool 100 is attached is extended from the front frame 204 when the front frame 204 of the spectacle frame 200 is about to slip off in a state of being mounted as indicated by an arrow A in FIG. The temple 201 tries to move up and the ear contact portion 103 of the eyeglass fixture 100 tries to move upward. When the ear contact portion 103 tries to move upward, the ear contact portion 103 tries to rotate in the forward direction (the counterclockwise direction in FIG. 9) about the shaft member 102. At this time, the force with which the front end portion 104 of the ear contact portion 103 presses the back side of the ear increases, and as a result, relative movement between the ear contact portion 103 and the back side of the ear is prevented, and the temple 201 is displaced. The rise is blocked. Thus, the spectacle attachment 100 can prevent the spectacle frame 200 from slipping off.

In addition, when the spectacle frame 200 mounted as indicated by the arrow A in FIG. 9 is removed from the wearer, the entanglement of the hair on the spectacle mounting tool 100 is suppressed as follows. The eyeglass frame 200 attached as indicated by the arrow A in FIG. 9 can be removed from the wearer by lifting the temple 201 upward as indicated by the arrow B in FIG. In the spectacle frame 200 to which the spectacle attachment tool 100 is attached, the predetermined portion 203 of the temple 201 and the front end portion 104 of the ear contact portion 103 of the spectacle attachment device 100 are connected by an entanglement preventing member 106. For this reason, even if the temple 201 is lifted upward in order to remove the spectacle frame 200 from the wearer, the arrow passes between the predetermined portion 203 of the temple 201 and the front end portion 104 of the ear contact portion 103 of the spectacle attachment 100. It is difficult for hair to enter the site of the temple 201 of the ear contact portion 103 from the X direction. As described above, since it is difficult for hair to enter, it is possible to prevent the hair from being entangled with the spectacle attachment 100 when the spectacle frame 200 is removed from the wearer.
Japanese Patent No. 3526571

  The downward curvature of the rear portion of the temple 201 in the spectacle frame 200 varies. The temple 201 provided in the spectacle frame 200 has a relatively large downward curvature as shown in FIG. 10 (a), and the rear downward curvature as shown in FIG. 10 (b). And a straight temple (not shown) having a downward curvature of 0 or substantially zero. As shown in FIGS. 10A and 10B, when a spectacle frame 200 having a different curvature at the rear portion of the temple 201 to which the same spectacle mounting tool 100 is attached is attached, the entanglement preventing member 106 follows the temple 201, so that the spectacle frame The position of the front end portion 104 of the ear contact portion 103 when the 200 is worn is affected by the downward curvature of the rear portion of the temple 201. Further, the clip portion 101 to which the ear contact portion 103 is swingably attached via the shaft member 102, that is, the portion serving as the center of swinging of the ear contact portion 103 is attached to the rear portion of the temple 201. Therefore, the position of the portion that becomes the center of swinging of the ear contact portion 103 is also affected by the downward curvature of the rear portion of the temple 201. Therefore, when the spectacle frame 200 is worn, the positional relationship (the posture of the ear contact portion 103) between the front end portion 104 of the ear contact portion 103 and the portion that becomes the center of swinging of the ear contact portion 103 is the temple. 201 may change depending on the downward curvature of the rear part.

  Depending on the posture of the ear contact portion 103, the entire ear contact portion 103 may not contact the ear, and the ear contact portion 103 may not be firmly held by the ear. For this reason, depending on the downward curvature of the rear portion of the temple 201, the spectacle frame 200 may not be firmly held. Therefore, the same eyeglass fixture 100 cannot be suitably used for various eyeglass frames 200 having different curvatures at the rear portion of the temple 201.

  The present invention prevents the omission of the spectacle frame, prevents the hair from being entangled when the spectacle frame is detached from the wearer while being attached to the spectacle frame, and is suitable for various spectacle frames. It is an object of the present invention to provide a spectacle mount that can be used and a spectacle frame set including the spectacle mount and a spectacle frame.

  The present invention provides, as a first means, a spectacle attachment detachable to a spectacle frame comprising a front frame for holding a lens and a pair of temples extending rearward from both ends of the front frame, A bending member that bends along the back side, an ear pad member that is swingably attached to the bending member via a shaft member, and has an ear contact portion that can contact the back side of the ear; and A flexible entanglement preventing member for connecting a predetermined portion ahead of a portion to which the ear pad member is attached and a front end portion of the ear contact portion; and an upper surface or a side surface of the bending member. There is provided a spectacle mounting tool comprising a mounting member that is detachably fitted.

  The eyeglass attachment device according to the first means can be attached to the eyeglass frame by fitting the temple of the eyeglass frame to the attachment member. The spectacle frame to which the spectacle attachment device according to the first means is attached has the ear contact portion of the spectacle attachment device according to the first means hung on the back side of the ear, and the front end portion of the ear contact portion is curved by the ear. It can be mounted by pressing against the member side.

  The eyeglass fixture according to the first means and the temple of the eyeglass frame are separate members. For this reason, regardless of the downward curvature of the temple rear portion of the spectacle frame, the portion of the bending member to which the anti-entanglement member of the spectacle attachment tool is connected and the portion of the bending member to which the ear rest member is attached can be designed freely. The portion of the bending member to which the entanglement preventing member is connected and the portion of the bending member to which the ear contact member is attached are such that when the front end portion of the ear contact portion is pressed against the bending member side, the entanglement prevention member follows the bending member. It can be set as the part of a bending member which becomes a posture where a contact part contacts the back side of an ear. When the eyeglass attachment with the ear contact member attached to such a part is attached to the spectacle frame, the front end of the ear contact part is pressed against the curved member side, and the eyeglass frame is attached. The prevention member is along the curved member, and the ear contact portion comes into contact with the back side of the ear. Since the bending member is curved so as to be along the back side of the ear, the entanglement preventing member is along the bending member, so that the spectacle frame can be mounted without a sense of incongruity even when the spectacle mounting tool according to the first means is attached. In addition, the ear contact portion is firmly held by the ear by the posture in which the ear contact portion contacts the back side of the ear.

  The eyeglass attachment according to the first means, like the eyeglass attachment described in Patent Document 1, can prevent the eyeglass frame from slipping off. When the front frame of the spectacle frame to which the spectacle attachment device according to the first means is attached is about to slip off, the temple of the spectacle frame is about to slip up, and when the temple is about to slip up, the first means The ear contact portion of the spectacle mounting tool tends to move upward. When the ear contact portion moves upward, the force with which the front end portion of the ear contact portion presses the back side of the ear increases, and as a result, the relative movement between the ear contact portion and the back side of the ear is prevented. Thus, the temple is prevented from rising.

  Further, the eyeglass attachment device according to the first means, like the eyeglass attachment device described in Patent Document 1, may be entangled when the eyeglass frame is removed from the wearer while being attached to the eyeglass frame. It is suppressed. The spectacle frame to which the spectacle attachment according to the first means is attached can be removed from the wearer by lifting the temple upward. The bending member of the eyeglass fixture according to the first means and the front end portion of the ear contact portion are connected by an entanglement preventing member. For this reason, even if the temple of the spectacle frame is lifted upward in order to remove the spectacle frame to which the spectacle mount according to the first means is attached, the curved member of the spectacle mount and the ear contact portion It is difficult for the hair to enter the attachment site between the bending member and the ear pad member from between the front end portions, and it is possible to prevent the hair from being entangled with these.

  The spectacle attachment according to the first means can be suitably used for various spectacle frames. As described above, the spectacle frame to which the spectacle mount according to the first means is attached can be mounted by pressing the front end portion of the ear contact portion against the bending member side. When the front end portion of the ear contact portion is pressed against the bending member, the entanglement preventing member follows the bending member. Since the entanglement preventing member follows the curved member, the positional relationship between the front end portion of the ear contact portion and the portion connected to the curved member of the entanglement preventing member when the spectacle frame is worn is below the rear portion of the temple of the spectacle frame. Unaffected by the curvature of.

  In addition, as described above, when the front end portion of the ear contact portion is pressed against the bending member side, the bending member such that the entanglement preventing member is along the bending member and the ear contact portion is in contact with the back side of the ear. When the entanglement preventing member is connected to this part and the ear pad is attached, the positional relationship between the part connected to the curved member of the entanglement preventing member and the part attached to the curved member of the ear pad is constant.

  For this reason, when an entanglement prevention member is connected to such a part and an ear support member is attached, the part (ear part) attached to the front end part of the ear contact part and the bending member of the ear contact member when the spectacle frame is attached. The positional relationship (the position of the ear contact portion) with the swinging portion of the contact portion does not change depending on the downward curvature of the temple rear portion of the spectacle frame. If the posture of the ear contact portion does not change, the entire ear contact portion is in contact with the ear, and the eyeglass frame is easily held. Therefore, the spectacle attachment according to the first means can be suitably used for various spectacle frames.

  As described above, the eyeglass attachment device according to the first means prevents the eyeglass frame from falling off, and the hair is entangled when the eyeglass frame is removed from the wearer while attached to the eyeglass frame. It is suppressed and can be suitably used for various spectacle frames. In addition, if the spectacle attachment according to the first means is removed from the spectacle frame, the spectacle frame can be used as a normal spectacle frame.

  Preferably, in the eyeglass fixture according to the first means, the mounting member is provided on a side surface of the bending member, and has a concave groove opened downward so that the temple is detachably fitted. Is done.

  Such a spectacle mounting tool having a preferable configuration can be attached to the spectacle frame by fitting a temple into a concave groove opened downward. When the eyeglass attachment is about to fall downward from the temple in a state where the temple is fitted in the groove, the bottom of the groove is received by the temple. For this reason, according to this preferable structure, it is prevented reliably that a spectacles fixture falls out from a temple downward.

  Further, according to the present invention, as a second means, a spectacle frame having a front frame for holding a lens and a pair of straight temples extending backward from both ends of the front frame, and the straight temple are detachably fitted. A spectacle frame set comprising the spectacle mounting tool according to claim 1 or 2 is provided.

  As described above, the straight temple has a curvature of 0 or substantially below the rear part, and presses the side face of the face so that the wearer wears the spectacle frame. The temple of the eyeglass frame provided in the eyeglass frame set according to the second means is a straight temple. For this reason, in the spectacle frame set according to the second means with the spectacle attachment attached to the spectacle frame, the ear contact portion of the spectacle attachment is hung on the back side of the ear, and the front end portion of the ear contact portion is While pressing against the curved member side, it can be mounted by pressing the side of the face with a straight temple. For this reason, at the time of wearing, not only the ear contact portion is held by the ear, but also the straight temple presses the side surface of the face, so that the eyeglass frame set according to the second means is more slipped off. Difficult and more stable when worn. Moreover, if the spectacle attachment is removed from the spectacle frame of the spectacle frame set according to the second means, the spectacle frame can be used as a normal spectacle frame.

  Further, the present invention is provided as a third means, a front frame holding a lens, a spectacle frame having a pair of temples extending backward from both ends of the front frame, and an inner surface of the temple, A member to be inserted having an insertion hole, and a spectacle attachment having an insertion member that is removably inserted into the insertion hole, the spectacle attachment being attached to the insertion member and extending along the back side of the ear A bending member that bends to the back, an ear pad member that is swingably attached to the bending member via a shaft member, and has an ear contact part that can contact the back side of the ear, and the ear pad member of the bending member There is provided a spectacle frame set comprising a flexible entanglement preventing member for connecting a predetermined portion in front of a portion to which the lens is attached and a front end portion of the ear contact portion.

  The eyeglass attachment provided in the eyeglass frame set according to the third means can be attached to the eyeglass frame by inserting the insertion member into the insertion hole of the inserted member provided in the temple of the eyeglass frame. The eyeglass attachment provided in the eyeglass frame set according to the third means is the same as the eyeglass attachment according to the first means except that the eyeglass frame attachment structure includes an insertion member instead of the attachment member. It is the composition. For this reason, the spectacle attachment provided in the spectacle frame set according to the third means can obtain the same effect as the spectacle attachment according to the first means.

  The member to be inserted is provided on the inner surface of the temple of the spectacle frame. For this reason, it is difficult for the inserted member to appear on the appearance of the spectacle frame. Therefore, by removing the eyeglass attachment from the eyeglass frame, the eyeglass frame included in the eyeglass frame set according to the third means can be used as a normal eyeglass frame as if no inserted member is provided.

FIG. 1 is a diagram showing a configuration of a spectacle mounting tool 1 according to this embodiment, FIG. 1 (a) shows a side view of the spectacle mounting tool 1, and FIG. 1 (b) shows an arrow Y in FIG. 1 (a). The front view of the spectacle attachment 1 seen from the direction is shown, and FIG. 1C shows an enlarged side view of the attachment member 5 constituting the spectacle attachment 1.

  As shown in FIG. 1A, the eyeglass fixture 1 includes a bending member 2, an ear pad member 3, an entanglement preventing member 4, and an attachment member 5.

  The bending member 2 is a member that is bent downward along the back side of the ear. The ear pad member 3 is a member having an ear contact portion 31 that can contact the back side of the ear and a swinging portion 33 that is swingably attached to the bending member 2 via a shaft member 32. The entanglement preventing member 4 is a flexible member that connects the predetermined portion 22 ahead of the portion 21 to which the ear pad member 3 of the bending member 2 is attached and the front end portion 31 a of the ear contact portion 31.

  In the present embodiment, the ear pad member 3 and the entanglement preventing member 4 are integrally formed of an elastic member such as an elastomer. As shown in FIG. 1A, the entanglement preventing member 4 is thinner than the ear pad member 3 and is more easily bent than the ear pad member 3.

The predetermined portion 22 of the bending member 2 to which the entanglement preventing member 4 is connected and the portion 21 of the bending member 2 to which the ear pad member 3 is attached press the front end portion 31a of the ear contact portion 31 to the bending member 2 side. As shown in FIG. 1A, the entanglement preventing member 4 is a portion of the bending member 2 along the bending member 2 so that the ear contact portion 31 contacts the back side of the ear. The entanglement preventing member 4 has a posture in which an elastic force f _A that presses the front end portion 31a of the ear contact portion 31 against the bending member 2 side and an elastic force that separates the front end portion 31a of the ear contact portion 31 from the bending member 2. It is configured to be switched to a posture in which f _B acts (a posture indicated by a broken line in FIG. 1A). Since the entanglement preventing member 4 is configured in this way, the elastic force f _A on the side where the front end portion 31a of the ear contact portion 31 is closer to the bending member 2 than the force switching point with the predetermined position as the force switching point. The front end portion 31a of the ear contact portion 31 is held in a state of being pressed against the bending member 2 side. On the other hand, when the front end portion 31a of the ear contact portion 31 is located away from the bending member 2 from the force switching point, the direction in which the elastic force acts is reversed by the bending of the entanglement preventing member 4, and the elastic force f _B acts and the front end portion 31 a of the ear contact portion 31 is held in a state of being separated from the bending member 2.

  As shown in FIGS. 1A and 1B, the attachment member 5 is a member that is provided on the inner surface of the bending member 2 and that the temple of the spectacle frame is detachably fitted to. The attachment member 5 has a concave groove 51 opened downward so that the temple is detachably fitted. On the inner side surface 52 of the mounting member 5 that partitions the concave groove 51, a protrusion 53 that protrudes inside the concave groove 51 is formed. As shown in FIG. 1C, the protrusion 53 extends in the front-rear direction.

  FIG. 2 is a view showing the spectacle frame 6 to which the spectacle attachment 1 is attached, FIG. 2 (a) shows a side view of the spectacle frame 6, and FIG. 2 (b) shows a CC of FIG. 2 (a). A cross-sectional view is shown. As shown in FIG. 2, the spectacle frame 6 includes a front frame 62 that holds the lens 63 and a pair of temples 61 that extend rearward from both ends (both ends in the left-right direction) of the front frame 62. The spectacle mount 1 can be attached to the spectacle frame 6 by fitting the temple 61 of the spectacle frame 6 into the concave groove 51 of the mounting member 5 of the spectacle mount 1.

FIG. 3 is a schematic side view of the eyeglass frame 6 when the eyeglass frame 6 to which the eyeglass fixture 1 is attached is attached. The spectacle frame 6 to which the spectacle fixture 1 is attached can be mounted as follows. First, as shown by a broken line in FIG. 1 (a), the front end portion 31a of the ear contact portion 3 is separated from the bending member 2, and subsequently, as shown by an arrow E in FIG. 31 is hung on the back side of the ear from above, the temple 61 is lowered, and the front end portion 31a of the ear contact portion 31 is pressed against the bending member 2 side with the ear. When pressed ear bending member 2 side front end portion 31a in the ear of the contact portion 31, the front end portion 31a of the ear contacting portion 31 is moved to the switching point of the above-mentioned force by the elastic force f _A, the ear contacting The front end portion 31a of the portion 31 is pressed against the bending member 2 side. Thus, in the state where the front end portion 31a of the ear contact portion 31 is pressed against the bending member 2 side, as shown by the arrow D in FIG. Will be in contact with the back side of the ear. The bending member 2 is bent along the back side of the ear. Accordingly, since the entanglement preventing member 4 extends along the bending member 2, the spectacle frame 6 can be mounted without a sense of incongruity even when the spectacle attachment 1 is attached to the spectacle frame 6. Moreover, the ear | edge contact part 31 is firmly hold | maintained at an ear | edge by becoming the attitude | position which the ear | edge contact part 31 contact | abuts to the back side of an ear.

Also, as described above, the front end portion 31a of the ear contacting portion 31 when mounting the eyeglass frame 6 is moved to the switching point of the force by the elastic force f _A, tangle preventing member 4 along the curved member 2, The ear contact portion 31 comes into contact with the back side of the ear. For this reason, when the spectacle frame 6 is mounted, the entanglement preventing member can be used without pressing the front end portion 31a of the ear contact portion 31 to the bending member 2 side until the entanglement preventing member 4 extends along the bending member 2. 4 is along the bending member 2 and the ear contact portion 31 is in contact with the back side of the ear. Therefore, when the spectacle frame 6 is worn, the entanglement preventing member 4 easily follows the bending member 2 and is easily in a posture in which the ear contact portion 31 is in contact with the back side of the ear. Therefore, the spectacle frame 6 to which the spectacle mounting tool 1 is attached can be easily and securely attached without feeling uncomfortable.

  In this way, the mounted spectacle frame 6 is prevented from slipping off by the spectacle mounting tool 1. As shown in FIG. 3, when the front frame 62 of the spectacle frame 6 is about to slip off, the temple 61 extended to the front frame 62 tries to slip up, and the ear contact member 3 of the spectacle attachment 1 is in contact with the ear. The part 31 is going to be moved upward. When the ear contact part 31 of the ear pad member 3 tries to move upward, the ear contact part 31 tries to rotate in the forward direction (left-handed direction in FIG. 3) about the shaft member 32 (see FIG. 3). 3 is going to be in the state indicated by the arrow E).

  At this time, the force with which the front end portion 31a of the ear contact portion 31 presses the back side of the ear increases, and as a result, the relative movement between the ear contact portion 31 and the back side of the ear is prevented (in FIG. Attempting to return to the state indicated by D) prevents the temple 61 from slipping up. In this way, the spectacle frame 6 is prevented from slipping off by the spectacle attachment 1.

  3 can be removed from the wearer by lifting the temple 61 upward as indicated by the arrow E in FIG. The curved member 2 of the eyeglass fixture 1 and the front end portion 31 a of the ear contact portion 31 are connected by the entanglement preventing member 4. Therefore, even if the temple 61 of the spectacle frame 6 is lifted upward in order to remove the spectacle frame 6 to which the spectacle attachment 1 is attached, the bending member 2 of the spectacle attachment 1 and the front end portion of the ear contact portion 31 are removed. It is difficult for hair to enter from the direction of the arrow W in FIG. 3 into the attachment portion (swinging portion 33) between the bending member 2 and the ear pad member 3 from between 31a, and the swaying portion 33 is prevented from getting tangled with hair. .

  In addition, as described above, the entanglement preventing member 4 follows the bending member 2 in the state in which the spectacle frame 6 to which the spectacle attachment 1 according to the present embodiment is attached is attached. Since the entanglement preventing member 4 is along the bending member 2, the positional relationship between the front end portion 31 a of the ear contact portion 31 when the spectacle frame 6 is worn and the predetermined portion 22 connected to the bending member 2 of the entanglement preventing member 4. Is not affected by the downward curvature of the rear portion of the temple 61 of the spectacle frame 6. Further, the positional relationship between the predetermined portion 22 connected to the bending member 2 of the entanglement preventing member 4 and the portion 21 attached to the bending member 2 of the ear pad member 3 is constant. For this reason, the front end portion 31a of the ear contact portion 31 when the spectacle frame 6 is worn and the portion 21 (the portion serving as the center of swinging of the ear contact portion 31) attached to the bending member 2 of the ear rest member 3. The positional relationship (the posture of the ear contact portion 31) does not change depending on the downward curvature of the rear portion of the temple 61 of the spectacle frame 6.

  4A shows a spectacle frame 6 provided with a temple 61 having a relatively large curvature downward in the rear, and FIG. 4B shows a spectacle frame 6 provided with a temple 61 having a relatively small curvature in the lower rear. The case where the spectacles fixture 1 is attached to is shown. As shown in FIGS. 4A and 4B, the posture of the ear contact portion 31 of each spectacle mounting tool 1 when the front end portion 31 a of the ear contact portion 31 is pressed against the bending member 2 is a straight temple. This is the same as the case where the spectacle mounting tool 1 is attached to the spectacle frame 6 having (see FIG. 3).

  Thus, since the posture of the ear contact portion 31 does not change due to the downward curvature of the rear portion of the temple 61, the entire ear contact portion 31 does not contact the ear due to the downward curvature of the rear portion of the temple 61. The glasses frame 6 does not become difficult to be held. Therefore, the spectacle attachment 1 according to the present embodiment can be suitably used for various spectacle frames.

Further, when the spectacle frame 6 is worn, the elastic force f _A acts as described above, so that when the spectacle frame 6 is worn, the posture of the ear contact portion 31 can be easily applied to the back side of the ear. It becomes posture to touch. The posture of the ear contact portion 31 when the spectacle frame 6 is mounted does not change depending on the downward curvature of the rear portion of the temple 61 of the spectacle frame 6. For this reason, the spectacle frame 6 depends on the downward curvature of the rear portion of the temple 61. Does not become difficult to hold. Therefore, according to the spectacle attachment 1, even if it is the spectacle frame 6 which has the rear part of the temple 61 of any downward curvature, it can mount | wear easily and firmly.

  As described above, the spectacle attachment tool 1 prevents the spectacle frame 6 from slipping off, and prevents the hair from being entangled when the spectacle frame 6 is detached from the wearer while being attached to the spectacle frame 6. And, it can be suitably used for various spectacle frames 6.

  Further, as shown in FIG. 2B, the spectacle attachment 1 can be attached to the spectacle frame 6 by fitting a temple 61 into a concave groove 51 opened downward. When the eyeglass attachment 1 attempts to drop downward from the temple 61 while the temple 61 is fitted in the groove 51, the bottom 54 of the groove 51 is received by the temple 61. For this reason, the spectacle fixture 1 is reliably prevented from dropping downward from the temple 61. A projection 53 extending in the front-rear direction is formed on the inner side surface 52 of the attachment member 5 that partitions the concave groove 51. By forming the protrusions 53, the minimum distance (hereinafter referred to as “ditch groove”) of the length in the left-right direction of the groove 51 without increasing the thickness of the entire side surface portion of the mounting member 5 located on both sides of the groove 51 in the left-right direction. 51 ") can be shortened. By reducing the width of the concave groove 51, even a temple 61 having a small width can be fitted into the concave groove 51 by being sandwiched between the protrusions 53. If the entire side surface portion of the mounting member 5 is not thickened, the side surface portion can be easily bent and the width of the groove 51 can be easily increased. For this reason, even if the temple 61 is very long in the left-right direction as compared with the width of the groove 51, the width of the groove 51 can be increased and moved between the protrusions 53. If the temple 61 is moved between the protrusions 53 by expanding the width of the recess 51, the temple 61 is fitted into the recess 51 by being sandwiched between the protrusions 53. Therefore, by forming the protrusion 53, even the narrow temple 61 or the wide temple 61 can be fitted into the concave groove 51.
