[Problems to be solved by the device]

 However, in such a conventional technique, if the spectacle frame is assembled without using a special jig, the urging force of the spring is counteracted and the screw holes of the temple side hinges and the thread holes of the royal side hinges are opposed. The screw must be forcibly screwed into the screw hole so that and coincide with each other. At that time, the screw may fly and be lost, or the screw thread may be broken. Therefore, it is very difficult to assemble such a spectacle frame without using a special jig, and once it is disassembled, it cannot be easily dealt with by retailers and end users. There is a point. The present invention has been made in view of such conventional problems, and an object thereof is to provide an eyeglass frame that can be easily assembled without a special jig.

[0005]

[Means for Solving the Problems]

 A spectacle frame for achieving the above-mentioned object is such that a hinge member on a temple side is formed with a through hole, an elastic member is arranged in the through hole, and at least a part of the through hole is provided from one opening of the through hole. When the temple member that can be inserted into the through hole and is in an open state is further opened, the temple member is pushed by the main part of the hinge member on the side of the yoke, and the portion inserted into the through hole compresses the elastic member. An insertion state that has a pressing member and an insertion portion that can be inserted into the through hole from the other opening of the through hole, and that maintains the compressed state of the elastic member when the insertion portion is inserted into the through hole. And a second pressing member having a maintenance portion.

Further, in another spectacle frame for achieving the above object, a temple member and an armor member are openably and closably connected via a hinge member, and the temple member is detachably attached to the hinge member on the temple side. In the temple-replaceable ophthalmic frame provided, the hinge member on the temple side is provided with a through hole parallel to the longitudinal direction of the temple member when mounted, and the temple member is parallel to the through hole. A hook portion having an opening facing the mounting direction of the member approaching is formed, an elastic member is arranged in the through hole, and the temple member has an opening of the through hole that is different from the mounting direction. An insertion shaft that can be inserted into the through hole from the opening facing the removal direction in the opposite direction and that is parallel to the temple member body is formed, and swings with respect to the temple member body. A swingable portion, and an engaging portion that is engageable with the hook portion when a predetermined amount of the insertion shaft is inserted into the through hole is formed in a part of the swingable portion. At least a part of the opening of the through hole facing the mounting direction can be inserted into the through hole, and when the temple member in the open state is further opened, it is pushed by the main part of the hinge-side hinge member. The portion to be inserted into the through hole is provided with a pressing member for pressing and contracting the elastic member.

[0007]

[Action]

 When connecting the hinge member on the temple side and the hinge member on the end side with screws, leave the insertion part of the second pressing member in a state not inserted into the through hole, and insert the first pressing member. The part is left inserted in the through hole. At this time, the elastic member in the through hole is in a free state because one end thereof is not regulated.

In this state, move both hinge members so that the screw holes of the hinge member on the temple side and the screw holes of the hinge members on the armor side are aligned, and when the screw holes are aligned with each other, insert a screw here. Screw in. During this series of operations, since the elastic member is in the free state as described above, the first pressing member in contact with the hinge-side hinge member is not pressed by the elastic member, and the screw hole of the temple-side hinge member is not pressed. No special force is required to align with the threaded holes in the hinges on the side of the end. Therefore, the temple-side hinge member and the endurance-side hinge member can be easily connected without using a special jig. When the connection between the temple-side hinge member and the endurance-side hinge member is completed, the insertion part of the second pressing member is inserted into the through hole, the elastic member is compressed, and this state is maintained by the insertion state maintaining unit. .

In this way, the assembled spectacle frame is opened. When a force for further opening is applied to the temple member in the open state, the first pressing member is pressed by the main part of the yoke hinge member, and the elastic member that is compressed is further pressed. Since it is contracted, a restoring force acts to restore the temple member to its original open state.

【Example】

 An embodiment of the spectacle frame according to the present invention will be described below with reference to FIGS. In the spectacle frame of this embodiment, as shown in FIG. 2, a temple member 30 is detachably attached to the temple-side hinge member 20.

A temple-side hinge member 20 is connected via a screw 19 to the yoke-side hinge member 15 that is fixedly mounted on the armor member 10. The temple-side hinge member 20 is formed with a through hole 21 parallel to the longitudinal direction of the temple member 30 when the temple member 30 is mounted. A spring 24, which is an elastic member, is inserted into the through hole 21, and a ball 23, which has almost the same inner diameter as the through hole, is inserted into the through hole 21 on the side of the opening 22 facing the removing direction B. There is. Further, a hook portion 25 is formed on the outer side surface 26 of the temple-side hinge member 20 (the side opposite to the side in contact with the user's head) near the opening 27 facing the attachment direction A of the through hole 21. . The hook portion 25 has an opening in the mounting direction A of the temple member 30.

The opening 27 of the through hole 21 facing the mounting direction A is closed by inserting the insertion portion 41 of the pressing member 40 from there. The pressing member 40 has a flange portion 42 so that the pressing member 40 does not completely enter the through hole 21. A bottom surface 43 of the pressing member 40 is formed flat and is in contact with the hinge-side hinge member 15. On the armature side hinge member 15, a flat open state contact surface 16 that contacts the bottom surface 43 of the pressing member 40 when the temple member 30 is in the opened state (the temple member 30 and the armor member 10 are substantially at right angles), A flat closed-state contact surface 17 that contacts the bottom surface 43 of the pressing member 40 when the temple member 30 is in the closed state (the temple member 30 and the armor member 10 are substantially parallel to each other) is formed. The contact surface 17 in the closed state is formed to face the head side (inner side) of the user when using glasses, and the contact surface 16 in the open state is substantially perpendicular to the contact surface in the closed state. Is formed.

The temple member 30 can be inserted into the temple member main body 31 having an ear hooking portion (not shown) formed at one end and the opening 22 of the through hole 21. The insertion shaft 33 and a swinging portion 35 that is swingably provided at the other end of the temple member body 31 are configured. The insertion shaft 33 is parallel to the temple member body 31, and when the insertion shaft 33 is inserted into the through hole 21, the inner side surface 32 of the temple member body 31 and the outer side surface 26 of the temple side hinge member 20 are in contact with each other. The temple member body 31 is formed. The swinging portion 35 has an engaging pin 36 that engages with the hook portion 25 of the temple-side hinge member 20 when the insertion shaft 33 is inserted into the through hole 21 of the temple member 30 by a predetermined amount, and the hook portion 25. A cover 37 is formed to cover the engagement pin 36 and the engagement pin 36 when they are engaged with each other. The hook portion 25 of the temple-side hinge member 20 is connected to the inner side surface 32 of the temple member main body 31 and the temple side when the insertion shaft 33 is inserted into the through hole 21 in a fixed amount and engages with the engagement pin 36 of the temple member 30. The side hinge member 20 is provided on the temple side hinge member 20 near the end piece 15 so that the contact area with the outer side surface 26 of the side hinge member 20 becomes large.

The spring 24 inserted into the through hole 21 has one end in contact with the ball 23 and the other end in contact with the insertion portion 41 of the pressing member 40. As shown in FIG. 2, the spring 24 has a structure in which the temple-side hinge member 20 is open and the insertion shaft 33 of the temple-side hinge member 30 is not inserted into the through hole 21 of the temple-side hinge member 20. It is mostly free.

Next, the operation of this embodiment will be described. First, the operation of connecting the temple-side hinge member 20 and the endurance-side hinge member 15 will be described. This connecting operation is performed in a state where the temple member 30 is not attached to the temple-side hinge member 20.

As shown in FIG. 6, after inserting the ball 23 and the spring 24 into the through hole 21 from the opening 27 of the through hole 21, the insertion portion 41 of the pressing member 40 is also inserted into the through hole 21. After that, the temple-side hinge member 20 is arranged substantially at right angles to the armor member 10, and the temple-side hinge member is aligned so that the screw holes of the temple-side hinge member 20 and the armor-side hinge member 15 are aligned. 20 is moved relative to the hinge member 15 on the end side. When the screw holes of the temple-side hinge member 20 and the screw holes of the armor-side hinge member 15 match, this state is maintained, and the screw 19 is screwed into the screw hole to connect the two.

When the threaded holes of the temple side hinge member 20 and the threaded holes of the end piece hinge members 15 are aligned with each other, the contact surface 16 of the end piece hinge members 15 in the open state and the bottom surface 43 of the pressing member 40 are in contact with each other. The insertion portion 41 of the pressing member 40 and the spring 24 are in contact with each other. However, in this state, as described above, the spring 24 is almost free, so that the screw holes of the temple-side hinge member 20 and the screw holes of the armor-side hinge member 15 are aligned with each other. Even when the hinge member 20 is moved, even when the screw hole of the temple-side hinge member 20 and the thread hole of the armor-side hinge member 15 are maintained in the same state, the force against the spring 24 is , Almost unnecessary. Further, it is not necessary to hold the insertion portion 41 of the pressing member 40 with a jig or the like so that the insertion portion 41 is inserted into the through hole 21. Therefore, the temple-side hinge member 20 can be easily connected to the armor-side hinge 15.

Next, a mounting operation of the temple member 30 will be described. As shown in FIG. 2, the temple member 30 is moved in the mounting direction A so that the insertion shaft 33 of the temple member 30 is inserted into the through hole 21 of the temple-side hinge member 20. As shown in FIG. 3, the temple member 30 is further moved in the mounting direction A, the insertion shaft 33 is inserted into the through hole 21, and the engaging pin 36 of the swinging portion 35 can be engaged with the hook portion 25. 1, the swinging portion 35 is swung to engage the engaging pin 36 with the hook portion 25, as shown in FIG. At this time, the spring 24 is compressed by the insertion shaft 33, and a force acts on the engagement pin 36 in a direction to engage with the hook portion 25. Therefore, unless a detaching operation described later is performed, the temple member is removed. 30 does not come off from the temple side hinge member 20.

Further, as shown in FIG. 1, when the temple member 30 is attached to the temple side hinge member 20, the movement of the insertion shaft 33 is restricted by the through hole 21, and the engagement pin 36 is locked by the hook portion 25. The temple member main body 31 is restricted in movement by the outer side surface 26 of the temple-side hinge member 20, and in the end, the temple member 30 is restricted in movement in three places by the temple-side hinge member 20. Moreover, the contact area between the inner side surface 32 of the temple member main body 31 and the outer side surface 26 of the temple side hinge member 20 is relatively large. Therefore, the temple member 30 is securely fixed to the temple-side hinge member 20 without backlash.

Further, the hook portion 25 provided on the outside of the temple-side hinge member 20 and the engagement pin 36 of the temple member 30 are covered with the cover 37 of the swinging portion 35, and from the end portion of the armor member 10. The outer side of the spectacle frame extending up to the temple member 30 is relatively flat and gentle, which is excellent in terms of design.

Next, an operation of removing the temple member 30 will be described. When removing the temple member 30 from the temple-side hinge member 20, the temple member 30 is once moved in the mounting direction A to release the engagement between the engagement pin 36 and the hook portion 25, and the engagement pin 36 is released. Swings the swinging portion 35 in a direction away from the hook portion 25. Then, in the temple member 30, the contracted spring 24 extends, moves in the removing direction B, and is disengaged from the temple-side hinge member 20.

By the way, it is conceivable that a force is applied to the temple member 30 in the mounting direction A during the mounting state, and the engagement between the engagement pin 36 and the hook portion 25 material is released. However, in this case, since the engagement pin 36 receives a force in the engagement direction with the hook portion 25 by the spring 24, the temple member 30 is the temple-side hinge member 20 unless the swing portion 35 material swings. There is no more deviation. In addition, even if a force is applied to the temple member 30 in the mounting direction A during the mounting state, the temple member 30 is not easily disengaged. Therefore, the swinging portion 35 swings with a small force. So that the swinging portion 35 is firmly attached to the temple member main body 31, or a spring or the like is provided on the pin 38 for attaching the swinging portion 35 to the temple member main body 31, and the engaging pin 36 is attached to the hook portion 25. The swinging portion 35 may be biased in the direction of engaging with.

Next, a case where a force for further opening acts on the temple member 30 in the open state will be described with reference to FIGS. 1 and 4. As shown in FIG. 1, the temple member 30 in the open state is in a state substantially perpendicular to the armor member 10. In addition, in FIG. 1, since only the end of the endless member 10 is drawn, the endless member 10 and the temple member 30 appear to be parallel to each other, but the main part of the endless member 10 and the temple member 30 which are not shown are connected to each other. Is almost a right angle.

At this time, the flat bottom surface 43 of the pressing member 40 is in contact with the contact surface 16 of the similarly flat hinge-side hinge member 15 in the open state. The spring 24 inserted into the through hole 21 has one end in contact with the ball 23 and the other end in contact with the insertion portion 41 of the pressing member 40. It is compressed by the shaft 33. Therefore, due to the contracted spring 24, the pressing member 40 receives a force in the direction in which the pressing member 40 comes into contact with the hinge-side hinge member 15.

In such an open state, when the force F for further opening acts on the temple member 30, the bottom surface 43 of the pressing member 40 causes the corner portion (main part) 18 of the hinge-side hinge member 15 to move. In contact with the pressing member 40, the pressing member 40 is pressed by the corner portion 18 of the hinge-side hinge member 15, and the insertion portion 41 of the pressing member 40 is further inserted into the through hole 21. The panel 24 in the through hole 21 is pressed by the pressing member 40 and further compressed. Therefore, when the temple member 30 is further opened in the open state, the temple member 30 is further opened slightly, and a restoring force for returning to the original state (open state) is exerted.

The operation in the closed state will be described. As shown in FIG. 5, the temple member 30 in the closed state is substantially parallel to the armor member 10.

At this time, the flat bottom surface 43 of the pressing member 40 is in contact with the contact surface 17 of the similarly flat hinge-side hinge member 15 in the closed state. The spring 24 inserted into the through hole 21 is compressed by the insertion shaft 33 inserted into the through hole 21 as in the open state, and the pressing member 40 is separated from the spring 24. It receives a force in the direction of contact with the side hinge member 15.

When an attempt is made to open from this closed state, the bottom surface 43 of the pressing member 40 comes into contact with the corner portion 19 a of the contact surface 16 in the open state and the contact surface 17 in the closed state of the yoke side hinge member 15. After that, the contact member 16 must come into contact with the contact surface 16 of the hinge member 15 on the side of the open side. In other words, when the closed state is changed to the open state, the pressing member 40 is pushed by the corner portion 19a of the hinge-side hinge member 15 in the same manner as when the force for further opening from the opened state is exerted, and the pressing member 40 is pressed. The insertion portion 41 of 40 further enters into the through hole 21, and the spring 24 in the through hole 21 is pressed by the pressing member 40 and further compressed, so that a force that overcomes the force of the spring 24 is required. . Therefore, the spectacle frame in the closed state will not be in the open state unless the force to overcome the force of the spring 24 is exerted, and the temple member 30 is unnecessary when carrying the spectacle frame. There is no daze.

As described above, in this embodiment, the eyeglass frame can be easily assembled without using a special jig. Further, since the temple member 30 can be attached / detached only by moving the temple member 30 in the mounting direction A or the removing direction B and swinging the swinging portion 35, the temple member 30 can be easily replaced. .

It should be noted that in the above description, the hinge-side hinge member 15 and the temple-side hinge member 20 may be the hinges themselves, but not only the hinges but also those integrally formed therewith. May be included. In addition, although the present invention is applied to the temple-interchangeable eyeglass frame in the present embodiment, the present invention is not limited to this, and even if the present invention is applied to a temple in which temple members cannot be replaced. Good. Specifically, the insertion shaft 33 and the engagement pin 36 are provided separately from the temple member, and the temple member itself is fixed to the temple-side hinge member.

[0031]

[Effect of device]

 According to the present invention, since almost no force is applied from the elastic member when connecting the hinge member on the armature side and the hinge member on the temple side, it is possible to easily assemble the eyeglass frame without using a special jig. it can.
