Description

  The present invention relates to a spectacle frame, and in particular, the burden on the spectacle user associated with the replacement work is small, the user himself can easily and safely replace the temple, and the tip of the temple is appropriately placed on the back side of the ear. The present invention relates to a spectacle frame that can be attached in an engaged state and can maintain the state.

  The spectacle frame is configured by connecting members such as a front frame, a temple, and a hinge. Among the members that make up this spectacle frame, a pair of temples that can be freely opened and closed at both ends of the front frame and that frequently receives external force due to the user's opening and closing operations, etc. In the case of a type of temple, it is a member that needs to be relatively replaced because it tends to deteriorate with use. Further, in view of the trend of emphasizing decoration functions such as fashionability and design for the spectacle frames in recent years, TPO (Time, Place, Case (from the various decorated temples prepared in advance) Occasion)), it is possible to replace it with a favorite temple selected together.

  However, in order to replace the temple in a conventional general spectacle frame in which the temple is opened and closed by a screw constituting the hinge, the position where the temple can be removed using a tool such as a screwdriver for the eyeglass frame. After replacing the temple, it is necessary to re-tighten the screw, and it takes time and effort, and depending on the screw tightening condition when re-tightening the screw, the screw may loosen. Adjustment is required. For this reason, it is difficult for the eyeglass user himself to change the temple.

  Therefore, as a structure that allows the temple to be replaced without loosening the hinge screw, for example, a structure is proposed in which a connecting mechanism portion is provided to removably screw the temple around the extending direction at a required portion of the temple. (See Patent Document 1).

  More specifically, in Patent Document 1, as a first embodiment, a socket piece formed inside and fixed to a base end of a temple and fixed to a take-out end of a hinge (hinge) A replacement mechanism that includes a coupling mechanism portion formed of a screw piece formed with a male screw, and that allows the temple to be replaced by screwing the female screw of the socket piece and the male screw of the screw piece together Is disclosed (paragraphs 0009 to 0011 of Patent Document 1 and FIG. 3).

  Patent Document 1 discloses, as a second embodiment, a replacement structure in which a socket piece and a screw piece are fixed opposite to those in the first embodiment (Patent Document 1, specification paragraph 0015, figure). 4)

Furthermore, Patent Document 1 discloses a replacement structure that is different from the first embodiment in that the socket piece can be separated from the temple as the third embodiment (see paragraph 0016 of the specification of Patent Document 1, FIG. 5)
Utility Model No. 3047731

However, the replacement structure described in Patent Document 1 has the following problems.
That is, in the structure of the first embodiment (FIG. 3 of Patent Document 1), when the temple is attached by picking and rotating the socket piece fixed to the base end of the temple, the socket piece and the temple are integrated. Will rotate. Therefore, depending on the tightening degree of the female screw formed inside the socket piece and the male screw of the screw piece, the position of the tip portion of the temple bent downward is different in the rotational direction. There is a risk that the temple will be attached in a state where it cannot be properly engaged with the back side of the lens.

  In addition, even if the temple can be attached in a state where the tip portion can be properly engaged with the back side of the ear, the socket piece female screw and the screw piece male screw When the screw is loosened, the temple rotates and the tip may move to an inappropriate position.

  Furthermore, when attaching and detaching the temple, by picking and rotating the socket piece, the bent tip portion of the temple also rotates together with the socket piece, so that the bent tip portion is an obstacle (for example, There is also a problem that it is necessary to be careful not to get caught in clothes or the like of the eyeglass user who performs the attaching / detaching operation.

  The problem described above also exists in the structure of the second embodiment (FIG. 4 of Patent Document 1) and the third embodiment (FIG. 5 of Patent Document 1).

  The present invention has been made to solve such problems of the prior art, the burden on the eyeglass user accompanying the replacement work is small, the user himself can easily and safely replace the temple, It is an object of the present invention to provide a spectacle frame that can be attached in a state in which the distal end portion of the temple is appropriately engaged with the back side of the ear and that can maintain the state.

  In order to solve the above-mentioned problem, the present invention provides a temple in which a male screw is formed on at least a part of the base end portion, and a top member constituting a hinge interposed between the temple and the front frame, A tubular mounting member that externally fits the base end portion of the temple and the tip end portion of the piece member, and has a female screw that is detachably screwed with the male screw on the inner surface of the temple side; In a state where the male screw and the female screw are screwed together, the distal end portion of the top member and the temple are prevented from relative rotation between the distal end portion of the top member and the proximal end portion of the temple. It is intended to provide a spectacle frame characterized in that the base end part of the eyeglass comes into contact.

  According to the eyeglass frame of the present invention, the male screw formed on the base end portion of the temple and the mounting member are gripped by gripping the temple and picking the cylindrical mounting member and rotating the mounting member around its axis. The female screw formed on the inner surface is screwed and the temple is attached to the attachment member. And the attachment member is attached to the front-end | tip part of the top member by externally fitting the front-end | tip part of the top member which comprises hinges. Therefore, the temple is attached to the tip of the top member, and can be rotated by a hinge and opened and closed at both ends of the front frame. In addition, when removing a temple, what is necessary is just to pick a cylindrical attachment member, grasping a temple, and to rotate an attachment member in the reverse direction to the time of attachment.

  Here, in the eyeglass frame according to the present invention, in a state where the male screw and the female screw are screwed together, relative rotation between the top end portion of the top member and the base end portion of the temple is prevented. It is comprised so that the front-end | tip part of a piece member and the base end part of a temple may contact | abut. With such a configuration, even if the male screw and the female screw are excessively tightened at the time of attachment, the top end portion of the top member and the base end portion of the temple are brought into contact with each other by contacting the top end portion of the top member and the base end portion of the temple. Relative rotation with the end portion (rotation around the axial direction of the male screw (or female screw)) is prevented. Therefore, in the state where the top end portion of the top member and the base end portion of the temple are in contact, a contact surface is formed so that the temple front end portion that is bent downward is in a position where it is properly engaged with the back side of the ear. It is possible to attach the temple at an appropriate position without changing the position of the distal end portion of the temple according to the tightening condition of the male screw and the female screw.

  In addition, even when the spectacle frame is repeatedly used, the relative rotation between the top end of the top member and the base end of the temple is prevented, so that the screw between the male screw and the female screw is not provided. The joint is difficult to loosen, and the temple tip can be held in an appropriate position.

  Furthermore, it is only necessary to attach and detach the temple by gripping the temple and gripping the tubular attachment member and rotating the attachment member around its axis, so that the bent tip is rotated when the temple is attached or detached. There is no danger of being caught on an obstacle.

  As described above, according to the spectacle frame according to the present invention, it is not necessary to use a tool or the like, and the temple can be attached and detached simply by picking the cylindrical attachment member while holding the temple and rotating the attachment member around its axis. Therefore, the burden on the eyeglass user associated with the replacement work is small, and the user can replace the temple easily and safely. In addition, since the top end of the top member and the base end of the temple are in contact with each other so as to prevent relative rotation, the top end of the temple is properly engaged with the back side of the ear. It is possible to attach in a state where it is in a state where it is possible to hold the state.

  In addition, the phrase “base end” in the present invention means a portion located on the front side (eye direction side) of each member when the spectacle frame is mounted, and the term “tip end” refers to the phrase of each member. It means the part located on the rear side (ear direction side).

  As a configuration in which relative rotation between the top end of the top member and the base end of the temple is prevented in a state where the top end of the top member and the base end of the temple are in contact with each other, for example, the top of the top member It is possible to adopt a configuration in which the contact surface between the portion and the base end portion of the temple is formed in an oblique direction with respect to a surface perpendicular to the axial direction of the male screw.

  Or you may employ | adopt the structure which the front-end | tip part of the said top member and the base end part of the said temple contact | abut.

  In order to reliably prevent the mounting member from falling off from the distal end portion of the top member, preferably, the mounting member has a locking portion extending radially inward from the base end portion of the mounting member. And the top member is configured to include an engaging portion that engages with the locking portion at the distal end portion.

  Alternatively, the mounting member includes an inner diameter reduced portion that is reduced in diameter from the temple side toward the top member side on the inner surface, and the top member is fitted to the inner diameter reduced portion at the tip portion. It is also possible to provide a reduced-diameter portion having a reduced diameter.

  With any of the above-described configurations, it is possible to reliably prevent the attachment member from falling off from the tip end portion of the top member to the temple side after the temple is removed.

  More preferably, the mounting member includes an annular groove or protrusion on the inner surface on the piece member side, and the frame member has an annular protrusion that fits into the groove or protrusion on the tip. Or it is comprised so that a ditch | groove may be comprised.

  According to such a configuration, since the groove (or ridge) of the attachment member and the protrusion (or groove) of the top member are fitted, the attachment member is removed from the tip of the top member after the temple is removed. It is possible to prevent the mounting member from moving from the tip of the top member toward the front frame side, and damage to the rubbed portion due to the friction between the members can be prevented. There is also the advantage that problems are less likely to occur.

  According to the spectacle frame according to the present invention, the burden on the spectacle user associated with the replacement work is small, the user himself can easily and safely replace the temple, and the tip of the temple is appropriately placed on the back side of the ear. It can be attached in an engaged state and can be maintained in that state.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a schematic configuration of a spectacle frame 10 according to an embodiment of the present invention. FIG. 2 is an enlarged plan view partially showing in cross section the vicinity of the right temple 2 of the pair of left and right temples 2 constituting the eyeglass frame 10 shown in FIG. 1 (showing the mounting member 4 in cross section). 2 (a) shows a state where the temple 2 is attached, and FIGS. 2 (b) and 2 (c) show a state where the temple 2 is removed. FIG. 3 is an AA arrow view of FIG.

  As shown in FIG. 1, the eyeglass frame 10 according to the present embodiment includes a front frame 1 that holds a lens, a pair of left and right temples 2 that extend rearward from the left and right ends of the front frame 1, a temple 2, and a front A top member 3 constituting a hinge interposed between the frame 1 and a cylindrical mounting member 4 is provided. In addition, the spectacle frame 10 includes an armor 5 attached to the front frame 1 and a nose pad 6 attached to the front frame 1.

  As shown in FIG. 2, the temple 2 has a male screw 2m formed on at least a part (the whole base end 2a in the example shown in FIG. 2) of the base end (portion located on the front side) 2a. Yes.

  As shown in FIG. 2, the base end portion 3 a of the top member 3 is rotatably attached to the alloy 5 by screws 7. That is, the hinge 5, the screw 7, and the frame member 3 constitute a hinge of the spectacle frame.

  As shown in FIG. 2, the attachment member 4 is a female fitting that externally fits the base end portion 2 a of the temple 2 and the tip end portion 3 b of the top member 3 and is detachably screwed to the inner surface on the temple 2 side with a male screw 2 m. A screw 4 is formed. More specifically, the mounting member 4 according to the present embodiment has an inner diameter substantially the same as the outer diameter of the tip portion 3b of the piece member 3, and thus is closely fitted to the tip portion 3b of the piece member 3. ing. However, it is in a fitting state that can rotate around the axis with respect to the tip 3b of the top member 3. Further, as shown in FIG. 3, the outer surface of the mounting member 4 is formed in a polygonal shape in a cross-sectional view so that it can be easily picked and rotated around its axis as will be described later. However, the present invention is not limited to this, and in addition to being able to be formed in a circular shape in cross-sectional view, it is also possible to form fine irregularities for preventing slippage on the outer surface.

  As shown in FIG. 2A, when the male screw 2m and the female screw 4m are screwed together, the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 are rotated relative to each other. It is set as the structure contact | abutted so that it may be blocked | prevented. More specifically, in the present embodiment, the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 are in contact, and the contact surfaces 2S and 3S are perpendicular to the axial direction of the male screw 2m. It is formed in an oblique direction with respect to the surface.

  In the eyeglass frame 10 having the above-described configuration, when the temple 2 is attached, the base end portion 2a of the temple 2 is brought close to the distal end portion of the attachment member 4 as shown in FIG. What is necessary is just to grip the attachment member 4 while gripping it and rotate the attachment member 4 around its axis. Alternatively, as shown in FIG. 2 (c), after the attachment member 4 is moved to the front frame side (left side in FIG. 2), the base end 2 a of the temple 2 is brought into contact with the front end 3 b of the top member 3. In this state, the attachment member 4 may be picked while holding the temple 2 and the attachment member 4 may be rotated around its axis. As a result, the male screw 2 m formed on the base end portion 2 a of the temple 2 and the female screw 4 m formed on the inner surface of the mounting member 4 are screwed together, and the temple 2 is attached to the mounting member 4. And the attaching member 4 is attached to the front-end | tip part 3b of the top member 3 by externally fitting the front-end | tip part 3b of the top member 3 which comprises a hinge as mentioned above. Accordingly, the temple 2 is attached to the front end portion 3b of the frame member 3, and can be rotated around the screw 7 by a hinge and opened and closed at both ends of the front frame 1. On the contrary, when removing the temple 2, the attachment member 4 may be picked while holding the temple 2, and the attachment member 4 may be rotated in the direction opposite to that at the time of attachment.

  Here, as described above, the eyeglass frame 10 according to the present embodiment has the distal end portion 3b of the top member 3 and the temple 2 in a state where the male screw 2m and the female screw 4m are screwed together (FIG. 2A). The base end portion 2a is in contact with each other, and the contact surfaces 2S and 3S are formed in an oblique direction with respect to a surface perpendicular to the axial direction of the male screw 2m. With such a configuration, even if the male screw 2m and the female screw 4m are excessively tightened during attachment, the front end portion 3b of the top member 3 is caused by the contact surfaces 2S and 3S being formed in an oblique direction. And the relative rotation between the temple 2 and the base end 2a of the temple 2 are prevented. Therefore, in a state where the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 are in contact with each other, the temple distal end portion 2b (see FIG. 1) that is bent downward is appropriate on the back side of the ear of the eyeglass frame 10 user. As long as the contact surfaces 2S and 3S are formed so as to be engaged with each other, the position of the temple tip 2b changes according to the tightening degree of the male screw 2m and the female screw 4m. It is possible to attach the temple 2 at an appropriate position.

  Further, even if the spectacle frame 10 is repeatedly used, the contact surfaces 2S and 3S are formed in an oblique direction, and relative rotation between the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 is prevented. Therefore, the screw engagement between the male screw 2m and the female screw 4m is difficult to loosen, and the temple tip 2a can be held at an appropriate position.

  Furthermore, since the temple 2 may be attached and detached by gripping the temple 2 and holding the temple 4 by rotating the attachment member 4 around its axis, the bent tip portion is attached when the temple 2 is attached or detached. There is no danger that 2a does not rotate and is caught by an obstacle.

  As described above, according to the spectacle frame 10 according to the present embodiment, the burden on the spectacle user associated with the replacement work is small, the user himself can easily and safely replace the temple 2, and the tip of the temple 2 can be replaced. The portion 2a can be attached in a state of being properly engaged with the back side of the ear, and the state can be maintained.

  In addition, the contact part vicinity of the base end part 2a of the temple 2 and the front-end | tip part 3b of the top member 3 is not restricted to the structure shown in FIG. 2, It can change into various suitable structures. FIGS. 4 to 6 partially show the vicinity of the right temple 2 in a cross section when another configuration is applied as a configuration in the vicinity of the contact portion between the proximal end portion 2a of the temple 2 and the distal end portion 3b of the top member 3. It is an enlarged plan view (showing the attachment member 4 in cross section). In addition, (a) of FIG. 5 shows an enlarged plan view, and (b) shows a BB arrow view of (a). Hereinafter, each configuration will be sequentially described with reference to FIGS. 4 to 6.

  In the configuration shown in FIG. 4, a male screw 2 m is formed on at least a part of the base end portion 2 a of the temple 2, similarly to the configuration shown in FIG. 2. However, the configuration shown in FIG. 4 is different from the configuration shown in FIG. 2 in that the male screw 2m is not formed near the contact surfaces 2S and 3S.

  With such a configuration as well as the configuration shown in FIG. 2, the burden on the eyeglass user accompanying the replacement work is small, the user himself can easily and safely replace the temple 2, and the distal end portion of the temple 2. 2a can be attached in a state where it is properly engaged with the back side of the ear, and this state can be maintained. Furthermore, unlike the configuration shown in FIG. 2, it is not necessary to form the male screw 2m in the vicinity of the contact surfaces 2S and 3S, so that there is an advantage that the processing is easy.

  In the configuration shown in FIG. 5A, the distal end portion 3b of the piece member 3 and the proximal end portion 2a of the temple 2 are brought into contact with each other. More specifically, as shown in FIG. 5 (b), the base end 2a of the temple 2 and the tip end 3b of the top member 3 are cross-sectional views in which either one of the left and right sides is missing in the contact portion. It is formed in a semicircular shape, and is configured to abut and fit with this. With such a configuration, the distal end portion 3b of the piece member 3 and the proximal end portion 2a of the temple 2 are in contact with each other so that relative rotation is prevented. In FIG. 5A, the base end portion 2a of the temple 2 and the tip end portion 3b of the top member 3 are formed in a semicircular shape in cross-sectional view in which one of the left and right sides is missing at the contact portion. However, the present invention is not limited to this, and can be formed in a semicircular cross-sectional view in which either one of the upper and lower sides is missing, and the base end 2a of the temple 2 and the front end 3b of the top member 3 are fitted. It is possible to adopt various forms as long as they are circular in cross-section in the combined state.

  With such a configuration as well as the configuration shown in FIG. 2, the burden on the eyeglass user accompanying the replacement work is small, the user himself can easily and safely replace the temple 2, and the distal end portion of the temple 2. 2a can be attached in a state where it is properly engaged with the back side of the ear, and this state can be maintained. Furthermore, unlike the configuration shown in FIG. 2, it is not necessary to form the male screw 2m in the vicinity of the contact portion, so that there is an advantage that processing is easy.

  The configuration shown in FIG. 6 is such that the distal end portion 3b of the piece member 3 and the proximal end portion 2a of the temple 2 are brought into contact with each other as in the configuration shown in FIG. However, unlike the configuration shown in FIG. 5, a male screw 2m is formed on the entire base end 2a including the vicinity of the contact portion.

  Further, the attachment member 4 and the top member 3 are not limited to the configuration shown in FIG. 2 but can be changed to various suitable configurations. FIGS. 7 to 9 are enlarged plan views partially showing the vicinity of the right temple 2 in a cross-section when the other structures are applied as the attachment member 4 and the piece member 3 (the attachment member 4 is shown in cross section). . Hereinafter, each configuration will be sequentially described with reference to FIGS. 7 to 9. In the following description, as the configuration in the vicinity of the contact portion between the proximal end portion 2a of the temple 2 and the distal end portion 3b of the piece member 3, the contact between the distal end portion 3b of the piece member 3 and the proximal end portion 2a of the temple 2 is described. The case where the surfaces 2S and 3S are formed obliquely with respect to the surface perpendicular to the axial direction of the male screw 2m (see FIG. 2) will be described as an example, but the present invention is not limited to this. The configuration described with reference to FIGS. 7 to 9 can be applied to the configuration described with reference to FIGS.

  In the configuration shown in FIG. 7, the attachment member 4 includes a locking portion 4 c that extends radially inward from the base end portion 4 a, and the top member 3 engages with the locking portion 4 c at the distal end portion 3 b. The engaging portion 3c is provided.

  According to such a configuration, after the temple 2 is removed, even if the attachment member 4 tries to move from the tip 3b of the top member 3 to the temple 2 side (the right side in FIG. 7), the locking portion 4c and the engagement portion By engaging with 3c, it cannot be moved to the temple 2 side any more, so that it is possible to prevent the attachment member 4 from falling off from the tip 3b of the top member 3. Further, even if the fitting state of the mounting member 4 and the piece member 3 is relaxed compared to the configuration shown in FIG. 2, a certain amount of gap is formed between the outer surface of the piece member tip 3b and the inner surface of the mounting member 4. Even if the engaging portion 4c and the engaging portion 3c are engaged, it is possible to prevent the attachment member 4 from falling off. Therefore, by relaxing the fitting state between the mounting member 4 and the top member 3, there is also an advantage that the mounting member 4 can easily rotate around the axis with respect to the top end portion 3b of the top member. Note that the locking portion 4 c is not necessarily provided over the entire inner surface of the mounting member 4, and a configuration in which the locking portion 4 c is provided in a part in the circumferential direction of the mounting member 4 can be employed.

  In the configuration shown in FIG. 8, the mounting member 4 includes an inner diameter reduced portion 4d whose diameter is reduced from the temple 2 side toward the top member 3 side on the inner surface, and the top member 3 has an inner diameter reduced portion 4d at the tip portion 3b. The diameter-reducing part 3d reduced in diameter so as to be fitted to is provided.

  Even in such a configuration, the attachment member 4 cannot move further to the temple 2 side by fitting the inner diameter reduced portion 4d and the reduced diameter portion 3d, as in the configuration shown in FIG. It is possible to prevent the attachment member 4 from falling off from the front end portion 3 b of the top member 3. Moreover, it is possible to relieve the fitting state of the attachment member 4 and the piece member 3, and this also has the advantage that the attachment member 4 can easily rotate around the axis with respect to the piece member tip 3b.

  In the configuration shown in FIG. 9, the mounting member 4 includes an annular ridge 4e on the inner surface of the piece member 3 side, and the piece member 3 includes an annular groove 3e that fits the protrusion 4e at the tip 3b. Is.

  Even in such a configuration, as in the configuration shown in FIGS. 7 and 8, the fitting member 4 cannot be moved further to the temple 2 side by fitting the convex strip 4 e and the concave groove 3 e. The attachment member 4 can be prevented from falling off from the tip 3b of the piece member 3, and the fitting state between the attachment member 4 and the piece member 3 can be relaxed. There is also an advantage that it is easy to rotate around the axis with respect to the member tip 3b. Furthermore, according to the configuration shown in FIG. 9, it is possible to prevent the attachment member 4 from moving from the front end portion 3 b of the top member 3 toward the front frame side (left side in FIG. 9). The member 4 and the base end 3a, the screw 7 and the armor 5 of the top member 3 rub against each other). However, when the configuration shown in FIG. 9 is adopted, the attachment member 4 cannot be moved to the front frame side (the left side of the drawing in FIG. 9) when attaching the temple 2, so that the base end portion 2a of the temple 2 is The attachment member 4 needs to be attached by a method in which the attachment member 4 is gripped while holding the temple 2 and the attachment member 4 is rotated around its axis while approaching the distal end portion of the attachment member 4.

  In the configuration shown in FIG. 9, the mounting member 4 has an annular ridge 4e on the inner surface of the piece member 3 side, and the piece member 3 has an annular groove 3e fitted to the ridge 4e at the tip 3b. Although it is the structure which comprises, it is also possible to set it as the structure which reverses a protruding item | line and a ditch | groove. That is, the same effect can be obtained when the mounting member 4 is provided with an annular groove on the inner surface on the top member 3 side, and the top member 3 is provided with an annular ridge that fits into the groove at the tip 3b. Can be played.

  As described above, according to the eyeglass frame 10 according to the present embodiment, it is not necessary to use a tool or the like, and only the gripping member 4 is picked while gripping the temple 2, and the mounting member 4 is rotated around its axis. Since the temple 2 can be attached and detached, the burden on the eyeglass user associated with the replacement work is small, and the user can replace the temple 2 easily and safely. Further, the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 are brought into contact so that relative rotation between the distal end portion 3b of the top member 3 and the proximal end portion 2a of the temple 2 is prevented. Therefore, the distal end portion 2a of the temple 2 can be attached in a state where it is properly engaged with the back side of the ear, and the state can be maintained.

  According to the spectacle frame 10 according to the present embodiment, the user can easily replace the temple. For example, as shown in FIG. The temple 2x can be replaced with a temple 2x having improved durability against an external force, or as shown in FIG. 10 (b), a favorite temple 2y selected in accordance with the TPO from various decorated temples prepared in advance. It is also possible to replace it.

  Further, it can be easily replaced with temples that can be applied when performing intense exercise such as sports, for example, temples 2z and 2z 'as shown in FIGS.

  The temple 2z shown in FIG. 11 has an ear contact portion 23a that can be in contact with the back side of the ear, and a shaft member 8 such as a pin or a screw for swingably mounting the tip end portion of the temple body and the ear contact portion 23a. The ear support member 23 having the swinging portion 23b to which the ear contact member 23 is attached, the predetermined portion 22b in front of the portion 22a to which the ear contact member 23 of the temple body is attached, and the front end portion 23c of the ear contact portion 23a are connected. And a flexible entanglement preventing member 9.

  In the spectacle frame to which the temple 2z is attached, the nose pad 6 (see FIG. 1) attached to the front frame 1 is hung on the nose and the ear contact portion 23a of the curved ear pad member 23 is placed on the ear. It is worn by hanging on the curved part of the back side (between ear and head).

  In such a spectacle frame, when the front frame 1 is about to slip off while wearing spectacles, the tip of the temple 2z extending from the front frame 1 tends to slip and is attached to the tip of the temple body. The ear contact part 23a of the ear contact member 23 is moved upward. Then, when the ear contact part 23a of the ear pad member 23 tries to move upward, the swinging part 23b (the part 22a to which the ear pad member 23 of the temple body is attached) which is a part attached to the temple body of the ear pad member 23. ), The ear contact portion 23a tends to rotate in the forward direction (counterclockwise in FIG. 11). At this time, the force with which the front end portion 23c of the ear contact portion 23a presses the back side of the ear increases, and as a result, relative movement between the ear contact portion 23a and the back side of the ear is prevented, and the tip of the temple 2z The shift of the part is prevented. In this way, it is possible to prevent the glasses from slipping off.

  Further, the swinging portion 23b is provided at a substantially intermediate portion in the longitudinal direction of the ear abutting portion 23a, and the swinging portion 23b and the temple body, which are parts attached to the temple body of the ear pad member 23, are configured. The part 22a to which the ear pad member 23 is attached is configured to be provided with a restriction mechanism C (see FIG. 11B) for restricting the swing range of the swing part 23b, and the temple body and the ear pad member. The shaft member 8 such as a pin or a screw is used for attachment to the swing portion 23b of the shaft 23. As shown in FIG. 11 (b), the regulating mechanism C is configured such that the support piece 38 of the swinging portion 23b of the ear pad 23 contacts the abutment surface 28 provided on the part 22a to which the ear pad member of the temple body is attached. It is the structure which controls rocking | fluctuation by contacting.

  By providing such a restriction mechanism C, the swing range of the ear pad member 23 is restricted, so that when the user wears glasses, the ear contact part 23a of the ear pad member 23 is placed at an appropriate position on the back side of the ear. It can make it contact | abut easily and can wear a user's spectacles more easily. Further, since the ear resting member 23 is attached to the temple body attachment portion 22a via the shaft member 8, there is little loss of force, and smooth rocking can be achieved easily and inexpensively. Further, by providing the restriction mechanism C around the axis of the shaft member 8, the restriction mechanism C can be easily configured. In addition, although the rocking | swiveling part 23b attached to the ear pad member 23 is attached to the shaft member 8 so that rocking is possible, a hole is made in the ear pad member 23 itself (ear contact part 23a), and the shaft member 8 is attached. The ear pad 23 may be attached to the temple body so as to be swingable. Moreover, the part 22a to which the ear pad member 23 of the temple body is attached is configured to be the tip of the temple 2z. In this case, even if the user has used a spectacle frame having a general shape even though the temple 2z of the spectacle frame and the ear resting member 23 have a structure that is not integral, they are worn without a sense of incongruity. be able to.

  Further, as shown in FIG. 11, the flexible entanglement preventing member 9 includes a predetermined portion 22b in front of a portion 22a to which the ear rest member 23 of the temple body is attached and an ear contact portion 23a of the ear rest member 23. It is attached so as to connect the front end 23c. By doing so, even when the temple 2z is lifted upward when removing the glasses, the entanglement preventing member 9 blocks the space between the temple body and the front end 23c of the ear contact portion 23a. Therefore, it is difficult for the hair to enter the attachment portion (swinging portion 23b) between the temple body and the ear contact portion 23a from the x direction (FIG. 11 (a)), and entanglement thereof is suppressed. Further, since the entanglement preventing member 9 has flexibility, it does not hinder the function of suppressing the omission of the spectacle frame. In this way, by connecting the predetermined portion 22b ahead of the portion 22a where the ear pad member 23 of the temple body is attached by the flexible entanglement preventing member 9 and the front end portion 23c of the ear contact portion 23a, It is possible to prevent the glasses from falling off without increasing the burden on the nose, and to prevent the hair from getting entangled with the glasses when the glasses are removed.

  A temple 2 z ′ shown in FIG. 12 includes a spectacle mounting tool 30. The eyeglass attachment 30 is an eyeglass attachment that can be attached to and detached from the eyeglass frame, and can be brought into contact with a clip portion 30d that can be attached to and detached from the distal end 2b of the temple body 2 as shown in FIG. The ear contact portion 30a includes a swing portion 30b to which a shaft member 7 such as a pin or a screw for swingably mounting the clip portion 30d and the ear contact portion 30a is attached. Further, the clip portion 30d and the ear contact portion 30a are attached to be swingable by a swinging portion 30b using a shaft member 8 such as a pin or a screw. Thereby, the temple main body 2 and the ear | edge contact part 30a of the spectacles attachment tool 30 are attached so that rocking | fluctuation is possible. Further, in the case where the temple body 2 has a shape that becomes thicker toward the rear part, the clip part 30d is prevented from falling off from the tip of the temple body 2 even if a predetermined margin is provided for the inner diameter of the clip part 30d. Is possible.

  Also, as shown in FIG. 12, one end is connected to the front end portion 30c of the ear contact portion 30a, and the other end is detachable from the predetermined portion 20 in front of the portion 2b to which the clip portion 30d of the temple body 2 is attached. A flexible entanglement preventing member 9 is further provided. The flexible entanglement preventing member 9 connects the predetermined portion 20 in front of the portion 2b where the clip portion 30d of the temple body 2 is attached to the front end portion 30c of the ear contact portion 30a of the eyeglass attachment 30. As a result, it is possible to prevent the glasses from slipping off without increasing the burden on the nose, and to prevent entanglement of the hair with the glasses when the glasses are removed. Furthermore, as a configuration for detachably attaching the other end of the entanglement preventing member 9 to the temple body 2, a clip portion 9a formed of a flexible member as shown in FIG. 12A is used.
