The long hole 21 having the opened opening 22 is formed. A ball 23, which has substantially the same diameter as the inner diameter of the long hole, is inserted into the long hole 21, and a spring 24, which is an elastic member, is further inserted inside the ball 23. Further, a hook portion 25 is formed on the outer side surface (the side opposite to the side in contact with the head of the user) 26 of the temple side hinge member 20. The hook portion 25 has an opening in the mounting direction A of the temple member 30.

The temple member 30 has a temple member main body 31 having an ear hooking portion (not shown) formed at one end thereof, and an insertable insertable portion into the elongated hole 21 of the temple side hinge member 20. The shaft 33 and a swinging portion 35 swingably provided at the other end of the temple member body 31 are configured.

The insertion shaft 33 is parallel to the temple member main body 31, and when the insertion shaft 33 is inserted into the elongated hole 21, 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 are separated from each other. The temple member main body 31 is formed so as to be in contact with each other. 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 elongated hole 21 of the temple member 30 by a predetermined amount in the swing portion 35. 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 has an inner side surface 32 of the temple member body 31 when the insertion shaft 33 is inserted into the elongated hole 21 by a predetermined amount and engages with the engagement pin 36 of the temple member 30. It is provided on the temple-side hinge member 20 near the end of the hinge member 15 so that the contact area between the temple-side hinge member 20 and the outer side surface 26 of the temple-side hinge member 20 becomes large.

Next, the operation of this embodiment will be described.

First, the 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 elongated 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 elongated 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 and contracted by the insertion shaft 33, and a force acts on the engagement pin 36 in a direction to engage the hook portion 25. Therefore, unless the removal operation described later is performed, the temple The member 30 does not come off from the temple-side hinge member 20.

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 elongated hole 21, and the engagement pin 36 is hooked. The movement of the temple member body 31 is regulated by the outer side surface 26 of the temple-side hinge member 20, and eventually the temple member 30 is regulated by the temple-side hinge member 20 at three locations. 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.

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.

As described above, in the present embodiment, no separate component other than the temple member 30 is used, and the movement of the temple member 30 in the mounting direction A or the removing direction B and the swinging portion 35 are performed. Since the temple member 30 can be attached and detached only by swinging, the attaching and detaching operation can be easily performed.

Further, since the temple member 30 in the attached state is restricted in movement by the temple side hinge member 20 at three places, the temple member 30 can be firmly fixed in the attached state.

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 formed integrally therewith. May be included.
