  In the spectacle frame disclosed in Patent Document 1, the user adjusts the insertion amount of the temple into the insertion hole of the temple before wearing, so that the distance from the front frame to the destination cell is a distance corresponding to the distance between his nose and ear. To wear. However, even after making such adjustments and actually wearing the spectacle frame, the distance from the front frame to the destination cell does not correspond to the distance between your nose and ear, It may not fit your ears. In such a case, it is necessary for the user to remove the worn glasses and adjust the amount of insertion into the temple insertion hole again. Therefore, in the spectacle frame of Patent Document 1, adjustment of the insertion amount with respect to the insertion hole of the temple may be required a plurality of times, and it may take time for mounting.

  This invention makes it a subject to provide the spectacles frame which fits a nose and an ear | edge, without performing such adjustment by himself / herself.

  In order to solve the above problems, the present invention has, as a first means, a front frame, a temple body extending rearward from the front frame, and an insertion hole extending rearward from the front end, The temple body and the tip cell are arranged so that the temple body includes a tip cell inserted into the insertion hole so as to be movable in the front-rear direction, and the front frame and the tip cell are attracted to each other in the front-rear direction. An elastic member to be coupled, an ear pad portion that is swingably attached to the tip cell via a shaft member, and has an ear contact portion that can contact the back side of the ear, and the ear pad portion of the tip cell An ear pad member having a flexible entanglement preventing portion for connecting a predetermined portion ahead of a portion to which the ear contact portion is attached and a front end portion of the ear contact portion, and the tip cell includes the predetermined portion, The part to which the ear pad of the tip cell is attached A side hole that communicates the insertion hole with the outside, and the temple body has a magnetized portion formed of a magnetic material or a magnet, and is formed on the ear pad member. Is provided with a projection that is inserted into the side hole and is magnetically attached to the magnetized portion when the tip cell is pressed against the tip cell, and prevents movement of the temple body in the front-rear direction. .

  The eyeglass frame according to the first means is a front frame, a temple having a temple main body and a tip cell, and an ear contact that is swingably attached to the tip cell via a shaft member and can contact the back side of the ear. And an ear pad member having a flexible entanglement preventing part for connecting a predetermined part ahead of the part to which the ear pad part of the front cell is attached and the front end part of the ear contact part. With. In the spectacle frame according to the first means, the front frame is fixed to the face (if the front frame is provided with a nose pad, the nose pad is hung on the nose), the ear pad is hung on the ear, When the member is pressed against the tip cell with the ear, the front frame is fixed to the face, and the ear resting member can be attached by hanging on the back side of the ear.

  Moreover, the temple main body and the tip cell of the spectacle frame applied to the first means are connected by an elastic member, and the temple main body and the tip cell are relatively movable. As described above, the temple body and the front cell are relatively movable so that the eyeglass frame applied to the first means is attached to the front frame and the front cell in which the temple extends rearward. It is possible to adjust the distance from the ear pad member. Therefore, the spectacle frame according to the first means can be worn by adjusting the distance between the front frame and the ear rest member based on the distance between the user's face and the ear.

  The aforementioned front cell has a side hole that communicates the insertion hole with the outside between the predetermined portion and the portion to which the ear pad portion of the previous cell is attached. There is a magnetized part formed of a magnet, and the ear resting member is inserted into the side hole when the ear resting member is pressed against the tip cell, and is magnetized with the magnetized part in the longitudinal direction of the temple body. Protrusions that prevent movement are formed. Therefore, the spectacle frame according to the first means is prevented from moving in the front-rear direction of the temple body at the same time as being worn, and the positions of the front frame and the ear resting member are fixed. Therefore, since the spectacle frame according to the first means is mounted, the distance between the front frame and the ear resting member is adjusted so that the front frame is fixed to the face and the ear resting member is placed on the back side of the ear. The user does not need to adjust the distance between the front frame and the destination cell based on the distance between his / her face and ear.

  Further, when the positions of the front frame and the ear pad member are fixed, it is possible to prevent the tip cell from moving toward the front frame due to the elastic force of the elastic member. Thereby, in the spectacle frame according to the first means, the ear pad attached to the front cell presses the back side of the user's ear wearing the spectacle frame according to the first means, and the user feels pain. Is prevented.

  In addition, when the spectacle frame according to the first means is attached, if the front frame tries to slip off, the tip cell tends to slip up, and the ear contact portion of the ear pad attached to the tip cell moves upward. Try to move. When the ear contact part of the ear pad is about to move upward, the ear contact part of the ear pad tends to rotate in the forward direction around the shaft member. At this time, 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, and the upward movement of the tip cell is prevented. Is done. Therefore, the eyeglass frame applied to the first means is prevented from slipping off.

  Furthermore, when removing the eyeglass frame according to the first means, even if the temple or the tip cell is lifted upward, the tip cell and the ear contact portion are blocked by the entanglement prevention portion, so that the hair is It is difficult to enter the attachment site between the tip cell and the ear pad, and the entanglement is suppressed. Note that the entanglement preventing portion has flexibility and does not hinder the swinging of the ear pad portion, and therefore does not hinder the function of preventing slipping off.

  In addition, the spectacle frame according to the first means adjusts the distance between the front frame and the front cell based on the distance between the user's face and the ear, and when the eyeglass frame is worn, the front frame is fixed to the face. The position of the front frame and the tip cell is fixed in a state where the member is hooked on the back side of the ear. That is, since the positions of the front frame and the front cell can be adjusted steplessly according to the distance between the user's face and ears, a higher fit can be obtained.

  As a specific configuration of the connection between the temple body and the tip cell, the elastic member is connected to the temple body and the tip cell in a state of being contracted from a natural length at the time of mounting, and the elastic member of the temple body The structure by which the site | part connected is located behind the site | part connected with the said elastic member of the said front cell can be mentioned.

  In such a specific configuration, the elastic member connects the temple body and the tip cell in a state where an extension force is generated, and pulls the temple body backward and the tip cell forward. Therefore, in such a specific configuration, the front frame and the front cell are attracted to each other by pulling the temple body backward and the front cell forward by the extension force of the elastic member.

  In addition, as another specific configuration of the connection between the temple body and the tip cell, the elastic member is connected to the temple body and the tip cell in a state of being extended from a natural length at the time of mounting, The structure connected to the said elastic member can mention the structure located ahead from the site | part connected with the said elastic member of the said front cell.

  In such a specific configuration, the elastic member connects the temple body and the tip cell in a state where contraction force is generated, and pulls the temple body backward and the tip cell forward. Therefore, in this specific configuration, the front frame and the front cell are attracted to each other by pulling the temple body backward and the front cell forward by the contraction force of the elastic member.

  Further, the present invention has, as a second means, a front frame, a temple main body extending rearward from the front frame, and an insertion hole extending rearward from the front end portion, and the temple main body A temple having a tip cell inserted into the insertion hole so as to be movable in the front-rear direction, and an elastic member that connects the temple body and the tip cell so that the front frame and the tip cell are attracted to each other in the front-rear direction. An ear pad portion having an ear contact portion that is swingably attached to the tip cell via a shaft member and can contact the back side of the ear, and a portion to which the ear pad portion of the tip cell is attached An ear resting member having a flexible entanglement preventing portion for connecting a predetermined portion further forward and a front end portion of the ear abutting portion, and the tip cell includes the tip portion and the tip cell. The insertion is performed between the ear pad and the part to which the ear pad is attached. A side hole that communicates with the outside, and is formed in the ear pad member. When the ear pad member is pressed against the tip cell, it enters the insertion hole through the side hole and comes into contact with the temple body. The eyeglass frame is provided with a protrusion that prevents the temple body from moving in the front-rear direction.

  The eyeglass frame according to the second means is that the movement of the temple body in the front-rear direction is prevented not by magnetic attachment between the temple body and the protrusion, but by the protrusion contacting the temple body. Different from the eyeglass frame according to the above.

  As a specific configuration for preventing the temple body from moving in the front-rear direction by the protrusions coming into contact with the temple body, the temple body has an engagement part that engages with the protrusions that have entered the insertion hole in the front-rear direction. A plurality of the protrusions may be configured to come into contact with and engage with the engaging portion to prevent the temple body from moving in the front-rear direction.

  In such a specific configuration, when the temple main body tries to move in the front-rear direction with the protrusion engaged with the engaging portion, the protrusion is received by the engaging portion, so that the temple main body moves in the front-rear direction. Is blocked. In such a specific configuration, since a plurality of engaging portions that engage the protrusions are provided in the front-rear direction, a plurality of distances between the front frame and the front cell are set according to the distance between the user's face and ear. Can be adjusted in stages.

  As another specific configuration for preventing the movement of the temple body in the front-rear direction by abutting the temple body with the temple body, when the projection part enters the insertion hole, the inner surface of the tip cell that forms the insertion hole The structure which clamps the said temple main body with the part and prevents the movement of the said temple main body in the front-back direction can be mentioned.

  In such a specific configuration, the temple body is prevented from moving in the front-rear direction by the frictional force generated between the protrusion and the temple body, and between the inner surface portion of the tip cell and the temple body. The spectacle frame having such a specific configuration adjusts the distance between the front frame and the front cell based on the distance between the user's face and ears, and the front frame is fixed to the face when worn. The temple body is clamped in a state where it is hooked on the back side of the ear, and the positions of the front frame and the tip cell are fixed. That is, the spectacle frame having such a specific configuration can obtain a higher fit because the position of the front frame and the front cell can be adjusted steplessly according to the distance between the user's face and ear.

  As another specific configuration for preventing the movement of the temple body in the front-rear direction by the protrusion portion coming into contact with the temple body, the temple body has an elastic portion formed of an elastic body, and the elastic portion is the protrusion. When the projection enters the insertion hole, the projection comes into contact with the elastic part of the temple body and pushes in the elastic part, so that the front end part and the rear end part of the elastic part are inserted. The structure which dents the part to exclude and prevents the movement of the said temple main body in the front-back direction can be mentioned.

  In such a specific configuration, the protruding portion formed on the ear pad member is in contact with the elastic portion provided on the temple body, and the portions excluding the front end portion and the rear end portion of the elastic portion are recessed. By engaging the protrusion and the elastic portion, the temple body is prevented from moving in the front-rear direction. Further, even in the spectacle frame having such a specific configuration, when the distance between the front frame and the front cell is adjusted based on the distance between the user's face and the ear, the front frame is fixed to the face and is worn. In a state where the member is hooked on the back side of the ear, the temple body is clamped, and the positions of the front frame and the tip cell are fixed. That is, the spectacle frame having such a specific configuration can obtain a higher fit because the position of the front frame and the front cell can be adjusted steplessly according to the distance between the user's face and ear.

  As another specific configuration for preventing the movement of the temple body in the front-rear direction by the projection part coming into contact with the temple body, the projection part has an elastic part formed of an elastic body, and the temple body is A convex portion having a shorter length in the front-rear direction than the elastic portion is formed, and when the protruding portion enters the insertion hole, the elastic portion is pressed into contact with the convex portion of the temple body, and the elastic portion The structure which prevents the movement of the said temple main body in the front-back direction can be mentioned because the part except a front-end part and a rear-end part is dented.

  In such a specific configuration, the convex portion formed on the temple body is in contact with the elastic portion of the protruding portion, and the portion excluding the front end portion and the rear end portion of the elastic portion is recessed, and the protruding portion and the protruding portion. When the elastic part of the part engages, the temple body is prevented from moving in the front-rear direction. Further, even in the spectacle frame having such a specific configuration, when the distance between the front frame and the front cell is adjusted based on the distance between the user's face and the ear, the front frame is fixed to the face and is worn. In a state where the member is hooked on the back side of the ear, the temple body is clamped, and the positions of the front frame and the tip cell are fixed. That is, the spectacle frame having such a specific configuration can obtain a higher fit because the position of the front frame and the front cell can be adjusted steplessly according to the distance between the user's face and ear.

  In the spectacle frame according to the second means, as a specific configuration of the connection between the temple body and the tip cell, the elastic member is connected to the temple body and the tip cell in a state of being contracted from a natural length when worn. And the structure connected to the said elastic member of the said temple main body can be mentioned behind the site | part connected with the said elastic member of the said front cell.

  In such a specific configuration, the elastic member connects the temple body and the tip cell in a state where an extension force is generated, and pulls the temple body backward and the tip cell forward. Therefore, in such a specific configuration, the front frame and the front cell are attracted to each other by pulling the temple body backward and the front cell forward by the extension force of the elastic member.

  Further, in the spectacle frame according to the second means, as another specific configuration of the connection between the temple body and the tip cell, the elastic member is stretched from a natural length at the time of wearing, and the temple body and the tip body are stretched. The structure which connects a cell and the site | part connected with the said elastic member of the said temple main body can mention the structure located ahead of the site | part connected with the said elastic member of the said front cell.

Therefore, in this specific configuration, the front frame and the front cell are attracted to each other by pulling the temple body backward and the front cell forward by the contraction force of the elastic member.

  In the eyeglass frame of the present invention, since the adjustment of the distance between the front frame and the front cell is performed simultaneously with the mounting, the adjustment of the distance between the front frame and the front cell is unnecessary.

(Embodiment 1)
1A and 1B are external views of a spectacle frame according to the present embodiment, where FIG. 1A is a side view and FIG. 1B is a plan view. As shown in FIG. 1, a spectacle frame 1 according to this embodiment includes a front frame 2, a temple 5, an elastic member, and a flexible member 10.

  The front frame 2 includes a pair of left and right lenses 21, a pair of left and right rim portions 22 that hold the pair of left and right lenses 21, a bridge portion 23 that connects the pair of left and right rim portions 22, and left and right rim portions 22. It has a pair of left and right nose pads 24 attached inside in the direction. On the left and right outer sides of the left and right rim portions 22 of the front frame 2 are continuously provided.

  The temple 5 has a temple body 3 and a tip cell 4 that extend rearward from the front frame 2. The temple body 3 is rotatably connected to the armor 25 via a hinge structure 26 at the front end. FIG. 2 is an enlarged longitudinal sectional view of a portion surrounded by a dotted line P in FIG. 1A. FIG. 2A shows a state in which the flexible member 10 is pressed against the lower surface portion of the tip cell 4 (first (Position) (b) shows an enlarged vertical cross-sectional view of the state in which the ear pad 10 is in a state separated from the tip cell 4 (second posture). As shown in FIG. 2, the temple body 3 has a magnetized portion 31 formed of a magnetic body or a magnet at the rear portion.

  The rear portion of the tip cell 4 is curved downward corresponding to the shape of the back side of the ear. The tip cell 4 has an insertion hole 41 extending rearward from the front end portion, and the temple body 3 is inserted into the insertion hole 41 so as to be movable in the front-rear direction. Further, the tip cell 4 has a side hole 44 below the insertion hole 41 that allows the insertion hole 41 to communicate with the outside on the lower side of the tip cell 4.

  The elastic member 6 connects the temple body 3 and the tip cell 4 so that the front frame 2 and the tip cell 4 are attracted to each other in the front-rear direction. The elastic member 6 is disposed in the insertion hole 41, one end portion is connected to the rear end portion 43 of the inner surface portion 42 of the tip cell 4, and the other end portion is positioned forward of the rear end portion 43. Is connected to the rear end portion 32. The natural length of the elastic member 6 is shorter than the length of the insertion hole 41 in the front-rear direction. Therefore, when a user or the like does not apply force to the temple body 3 or the tip cell 4, the elastic member 6 contracts. The rear end portion 32 of the temple body 3 is attracted to the vicinity of the rear end portion 43 of the inner surface portion 42 of the front cell 4. Therefore, when the user or the like does not apply force to the temple body 3 and the destination cell 4, the distance between the front frame 2 and the destination cell 4 is shortened. In addition, the part to which the one end part of the elastic member 6 is connected may be any part of the tip cell 4, and the part to which the other end part of the elastic member 6 is connected is the tip cell 4 to which one end part is connected. Any part of the temple body 3 may be used as long as it is in front of the part.

  The ear pad member 10 is swingably attached to the rear end part 45 of the tip cell 4 via the shaft member 11 and has an ear pad part 7 having an ear contact part 71 capable of contacting the back side of the user's ear. And the flexibility which connects the predetermined part 46 ahead of the site | part (rear end part 45) to which the ear pad part 7 of the tip cell 4 was attached via the shaft member 11, and the front end part 72 of the ear contact part 71. A tangling prevention unit 8 is provided. The ear pad 71 is curved corresponding to the shape of the back side of the user's ear. Further, the predetermined portion 46 to which the entanglement preventing portion 8 is connected is a tip portion of the tip cell 4, and a side surface is provided between the rear end portion 45 to which the ear pad portion 7 of the tip cell 4 is attached and the predetermined portion 46. A hole 44 is located. The entanglement preventing portion 8 is formed of an elastic member such as an elastomer. Thus, since the ear pad 7 is swingably attached via the shaft member 11 and the entanglement preventing part 8 is formed of an elastic member, the ear pad 10 is as shown in FIG. In addition, it is possible to switch between a state pressed against the lower surface portion of the front cell 4 (first posture) and a state separated from the front cell 4 (second posture) as shown in FIG. .

  The ear contact member 10 is inserted into the side hole 44 when pressed against the lower surface portion of the tip cell 4, that is, in the first posture, and is magnetically attached to the magnetized portion 31 of the temple body 3. A protrusion 9 is formed to prevent movement in the front-rear direction. The protruding portion 9 is formed of a magnetic material or a magnet so as to be magnetically attached to the magnetically attached portion 31 of the temple body 3. Specifically, when the magnetized portion 31 is formed of a magnetic material, the protruding portion 9 is formed of a magnet. When the magnetized part 31 is formed of a magnet, the projection 9 is formed of a magnet having a magnetic pole opposite to that of the magnetic body or the magnetized part 31. In addition, as long as the protrusion part 9 can be magnetically attached to the temple main body 3, only a part may be formed with the magnetic body or the magnet. Moreover, the magnetic attachment part 31 of the temple main body 31 should just be formed so that it can be magnetically attached to the projection part 9, for example, only in the lower surface part of the temple main body 3 in the predetermined distance from the rear-end part of the temple main body 3. It may be formed.

  The magnetic attachment between the magnetized portion 31 and the protruding portion 9 is such that the protruding portion 9 inserted into the side hole 44 is positioned in the side hole 44 as long as a magnetic force acts between the magnetically attached portion 31 and the protruding portion 9. This is possible even if the insertion hole 42 is not entered. However, in order to perform magnetic adhesion more reliably, it is desirable that the protruding portion 9 enters the insertion hole 42 through the side hole 44 and the protruding portion 9 is positioned or abutted in the vicinity of the magnetized portion 31. Therefore, when the ear resting member 10 is in the first posture, the protruding portion 9 enters the insertion hole 42 through the side hole 44 so that the protruding portion 9 can be positioned or contacted in the vicinity of the magnetized portion 31. The height (the length in the protruding direction) is preferably larger than the length of the side hole 44 (the length between the lower surface portion and the inner surface portion 42 of the tip cell 4). Further, the cross-sectional shape perpendicular to the projecting direction of the projecting portion 9 is such that the projecting portion 9 can be inserted into the side hole 44.

  As described above, when the tip cell 4 is in the first posture, the magnetized portion 31 and the protrusion 9 are magnetized to prevent the temple body 3 from moving in the front-rear direction. On the other hand, when the tip cell 4 is in the second posture, the magnetic body 31 and the protrusion 9 of the temple body 3 are not magnetically attached, so that the temple body 3 can be moved in the front-rear direction.

  The wearing of the spectacle frame 1 having the above configuration will be described. When wearing the spectacle frame 1, as shown in FIG. 2 (b), the ear resting member 10 is in the second posture, and the temple body 3 can be moved in the front-rear direction. FIG. 3 is an explanatory diagram for explaining the wearing procedure of the spectacle frame 1. FIG. 3A shows a state in which the ear pad member 10 is moved above the ear E while the nose pad 24 is hung on the nose. (B) shows the state in which the ear pad member 10 is pressed against the ear E and the ear pad member 10 is in the first posture. As shown in FIG. 3A, when the user puts the ear pad member 10 in the second posture, the user puts the tip cell 4 on the nose pad 24 so that the ear pad member 10 is positioned above the ear. Pull backwards. When the tip cell 4 is pulled rearward, the tip cell 4 moves rearward with respect to the temple body 3, and the elastic member 6 extends from the natural length. When the ear resting member 10 moves above the ear E, the ear resting member 10 is moved in the direction of arrow Y in FIG. 3A, and the ear resting member 10 is pressed against the ear E, as shown in FIG. Then, the ear resting member 10 is set to the first posture pressed against the tip cell 4. Thereby, while the nose pad 24 is hung on the nose, the ear pad member 10 has a shape corresponding to the tip cell 4 and the ear pad member 10 is hung on the back side of the ear E. Thereby, the spectacle frame 1 is attached.

  When the spectacle frame is in the first posture, the protrusion 9 is inserted into the side hole 44 as described above, and the protrusion 9 is magnetically attached to the magnetic attachment 31 of the temple body 3. When the projection 9 and the magnetized portion 31 are magnetized, the temple body 3 is prevented from moving in the front-rear direction, and the positions of the front frame 2 and the ear pad member 10 are fixed. Therefore, the spectacle frame 1 according to the present embodiment is positioned with the front frame 2 and the ear resting member 10 in the wearing state in which the nose pad 24 is placed on the nose and the ear resting member 10 is placed on the back side of the ear E simultaneously with the wearing. Therefore, it is not necessary to adjust the distance between the front frame 2 and the front cell 4 based on the distance between the user's own nose and the ear E.

  Further, when the positions of the front frame 2 and the front cell 4 are fixed at the time of mounting, it is possible to prevent the front cell 4 from moving toward the front frame 2 by the elastic force of the elastic member 6. Thereby, in the spectacle frame 1 according to the present embodiment, the ear pad 7 attached to the tip cell 4 presses the back side of the user's ear E wearing the spectacle frame 1 according to the present embodiment to the user. Pain is prevented from being felt.

  In addition, when the front frame 2 is about to slip off with the spectacle frame 1 according to the present embodiment mounted, the tip cell 4 tends to slip up, and the ear contact portion 7 attached to the tip cell 4 is in contact with the ear. The part 71 tries to move upward. When the ear contact part 71 of the ear pad 7 tries to move upward, the ear contact part 71 of the ear pad 7 tries to rotate in the forward direction about the shaft member 11. At this time, the force with which the front end portion of the ear contact portion 71 presses the back side of the ear is increased, and as a result, the relative movement between the ear contact portion 71 and the back side of the ear is prevented, and the displacement of the front cell 4 is prevented. The rise is blocked. In this way, the eyeglass frame 1 according to the present embodiment is prevented from slipping off.

  Further, when removing the eyeglass frame 1 according to the present embodiment, even if the temple body 3 and the tip cell 4 are lifted upward, the tip cell 4 and the ear contact portion 71 are blocked by the entanglement preventing portion 8. Therefore, it is difficult for the hair to enter the attachment site between the tip cell 4 and the ear pad 7 and the entanglement thereof is suppressed. The entanglement preventing portion 8 has flexibility and does not hinder the swinging of the ear pad portion 7, and therefore does not hinder the function of suppressing the slip-off.

  In the eyeglass frame 1 according to the present embodiment, the nose pad 24 is hung on the nose, the tip cell 4 is pulled backward, the ear pad member 10 is positioned above the ear, and the ear pad member 10 is in the first posture. In this state, the temple body 3 is prevented from moving in the front-rear direction and the position of the nose pad 24 and the tip cell 4 is fixed with the nose pad placed on the nose and the ear pad 10 on the back side of the ear. Is done. Therefore, since the position of the nose pad 24 and the tip cell 4 can be adjusted steplessly according to the distance between the nose and the ear, the eyeglass frame 1 according to the present embodiment can obtain a higher fit.

(Embodiment 2)
In the eyeglass frames according to the following second to fifth embodiments, the movement of the temple body in the front-rear direction is prevented from being formed by the ear rest member, not by the magnetic attachment between the temple body and the protrusion formed on the ear rest member. It differs from the spectacle frame 1 which concerns on a 1st means by the point implement | achieved when a protrusion part contact | abuts to a temple main body. The spectacle frames according to the second to fifth embodiments have the same configuration as that of the spectacle frame 1 according to the first embodiment except that the configuration for preventing the temple body from moving in the front-rear direction is different.
