As shown expanded in FIG. 4, both the cam surfaces 8 and 9 have inclined portions 81 and 91 that are inclined at the same angle to each other, and
It has engaging portions 82 and 92 that can engage with each other.

Each of the inclined parts 81 and 91 has a horizontal step part 81a in the middle.
, 91a are interposed, and the inclined portion 81 of the handle-side cam surface 8
is 60° and 120° in the circumferential direction due to this stepped portion 81a.
The other inclined part 91 is a stepped part 91a.
It is divided into three parts of 120° and 60° in the circumferential direction.

On the other hand, stoppers 71a and 6a that can be engaged with each other are provided on surfaces facing each other in the axial direction of the base end 71 of the tightening member 7 and the handle seat 6.
is formed, and by engaging these stoppers 71a and 6a, the rotation angle of the tightening member 7 is regulated to a constant (90°).

The rotation angle of the handle 4 is regulated to a constant level by engaging the stepped portion 81 a of the inclined portion 81 on the cam surface 8 of the tightening member 7 with the stepped portion 91 a of the handle-side cam surface 9. Ru.

That is, the handle 4 and the tightening member 7 are in a vertical position in the unlocked state, and in the locked state, the tightening member 7 is rotated forward by 90 degrees, and the handle 4 is moved to the stepped portion 81a as shown in the exploded view in FIG.
, 91a is set to rotate by an angle (150°) larger than that of the tightening member 7 by the circumferential displacement angle (60°).

Further, as shown in FIG. 3, the base end portion 71 of the tightening member 7 is
The member 7 is fitted onto the handle shaft 5 so that a gap m is formed between the member 7 and the handle seat 6 in the above-mentioned vertical position, so that the member 7 can move in the axial direction along the handle shaft 5 with a stroke of the above-mentioned gap m. It is configured to be able to slide.

Reference numeral 10 denotes a member for the fastening member 7, which is fixed to the matching frame 21 of the inner shoji 2.

This receiver has a distal end surface 7 of an engaging protrusion 72 on the upper part of the member 10.
Tapered surface 101 for guiding 2a. Engagement pieces 102 that engage with collars 73 that are loosely fitted onto the protruding rods 72 are provided at the edges of the central part on the outer shoji side.

Next, the effect will be explained.

When unlocked, both the tightening handle 4 and the tightening member 7 are in a vertical position, as shown in FIGS. 1 to 3 and by phantom lines in FIG. 6.

Further, the relative positional relationship between the cam surfaces 8, 9 of both 4, 7 is as shown in FIG.

When the handle 4 is rotated as shown in Fig. 5-6 in order to lock the inner and outer shoji 2, 3, the tightening member 7 is rotated 90 degrees forward in conjunction with this, and its engagement is rotated 90 degrees. Joint rod 72
The distal end surface 72a of the receiver is guided by the tapered surface 101, and the receiver is brought into pressure contact with the member 10 and engaged with the engagement piece 102 thereof.

As a result, the inner and outer shoji 2 and 3 are locked, and at the same time, both the left and right vertical frames 11 and 1 of the window frame 1 are locked.
Forced into 2.

In this case, the tightening member 7 begins to rotate at the same time as the handle 4 begins to rotate due to the contact resistance of the cam surfaces 8' and 9, the frictional resistance between the proximal end portion 71 of the member, and the handle shaft 5, and the like.

Then, the distal end surface 72a of the engaging protrusion 72 is connected to the tapered surface 10.
1 and rotational resistance is applied, the tightening member 7 stops and the cam surface 8 of the handle 4 comes into sliding contact with the cam surface 9 of the tightening member 7.

Due to the sliding action of the inclined portions 81.91 on the cam surfaces 8, 9, the clamping member 7 slides toward the member 10 side.

When the handle 4 is rotated by a certain angle in this way, the step 81a of the handle-side cam surface 8 is rotated by the step 9 of the tightening member-side cam surface 9.
1a, the tightening member 7 then
It rotates together with the handle 4 until it reaches the locked position.

Regarding the operation of the tightening member 7, in some cases the tightening member 7 slides in the axial direction while rotating at the same time as the handle 4 starts rotating, or the handle 4 rotates at a certain angle (60°). There may be a case in which the tightening member 7 begins to rotate due to the action of the step portions 81a and 91a, but in any case, the tightening member 7 does not change from the unlocked position to the locked position by operating the handle. There is no change in the effect that the receiver slides toward the member 10 during this time.

In this way, the handle operation causes the tightening member 7 to move from its original pressure contact position to the member 10.
In order to slide to the side, the tightening member 7 and the receiver are connected to the member 10.
The contact force between the two ends becomes extremely large.

Therefore, since the inner and outer shoji 2 and 3 are pressed in the closing direction with great force, the shoji 2 and 3 and the window frame vertical frames 11 and 12
The airtightness, watertightness, and soundproofing between the two will be significantly improved.

Note that when the handle 4 is rotated in the unlocking direction from the above-mentioned locked state, the cam surface 8,
Due to the engagement of the engagement surfaces 82, 92 of 9, the tightening member 7 rotates together with the handle 4, and both 4 and 7 return to their original vertical positions.

By the way, in the above embodiment, the rotation angle of the tightening member 7 is determined by the stopper 71 a of the member 7 and the stopper 6 of the handle seat 6.
Although the angle of rotation of the member 7 is regulated to be constant by a, the rotation angle of the member 7 may be regulated on the member 10 side.

As described above, according to the present invention, the clamping member can not only be rotated by a simple handle operation, but also the receiver can be slid toward the member. The inner and outer shoji can be strongly pressed in the closing direction by pressure contact, thereby significantly improving the airtightness, watertightness, and soundproofing between the two shojis and the vertical frames on both sides of the window frame (door frame). It is something that can be done.
