As shown in FIGS. 3a and 3, the side plate 6, which is the main member of the window frame side metal fitting A, is fixed to the vertical frame 4 of the window frame 1 with screws, etc., while the side plate 15, which is the main member of the shoji side metal fitting C, is Shoji 2
It is fixed to the vertical frame 5 with screws or the like.

As shown in FIG. 3, the window frame side metal fitting A has a main shaft 11 at the lower part of the side plate 6 that protrudes toward the vertical frame 5 of the shoji 2 that faces it, and above the side plate 15 of the shoji side metal fitting C that faces this. A secondary shaft 16 with a reduced head 17 having a rectangular cross section projects.

The bearing fitting B, which is equipped with a brake device between the two, has a bearing hole 18 below which rotates in loose engagement with the main shaft 11, and a bearing part 20 above which the countershaft 16 is inserted.
It has a child-shaped bearing structure 19, and its opening 21 is open diagonally upward.

The bearing fitting B is pivotally supported by the main shaft 11 of the window frame side fitting A, and supports the subshaft 16 of the shoji side fitting C with a U-shaped bearing part 20, and serves as a connecting member between the window frame side fitting A and the shoji side fitting C. It has become.

Further, the bearing fitting B is provided with a stop edge 22 below the bearing hole 18 so as not to rotate beyond a predetermined angle, for example α0.

Lower side plate 6 of window frame side metal fitting A and side plate 1 of shoji side metal fitting C
A hanging wall 8° 14 having a cross-sectional shape with the side plates 6 and 15 is erected above 5, and when the shoji 2 is in the closed position as shown in FIG. 4, the hanging walls 8 and 14 are on the same plane. form.

On the other hand, as shown in FIG. 3, a crank member 24 having an opening 23 that engages with the head 17 of the subshaft 16 of the shoji side metal fitting C is located between the bearing metal fitting B and the side plate 6 of the window frame side metal fitting A. It is configured to freely rotate together with the subshaft 16.

A pin 25 protrudes below the crank member 24 toward the side plate 6 of the window frame side metal fitting A.

FIG. 2 is a diagram showing the trajectory of each movement, with the position of the main shaft 11 as P and the positions of the sub shaft 16 and pin 25 as Qta1 when the shoji 2 is in the closed position. Supported by the bearing part 20, the shoji 2 moves from the shoji closed position shown in FIG. 4 to the position shown in FIG. 5, and then moves to the position shown in FIG. Lower part 26v of hanging wall 8? - When the shoji 2 rotates until it contacts and stops, that is, until the shoji 2 stops at this position with natural ventilation, the subshaft 16 moves in the direction of the arrow r from Q in an arc and reaches the position R; At this time, the pin 25 of the crank member 24 fitted to the head 17 of the subshaft 16 rotates from the position a□ in the direction of arrow C by the same arc angle as above, for example α0, and stops when it reaches the 8th point. do.

An arcuate guide groove a through which the pin 25 moves from al to S is bored in the side plate 6 of the window frame side metal fitting A.

Next, the shoji 2 is rotated 180°-α0 from the natural ventilation position shown in Fig. 6, through the horizontal position shown in Fig. 7, to the position shown in Fig. 8, that is, a position where the outer glass surface of the shoji 2 can be safely cleaned indoors. When the shoji 2 is stopped, the shoji 2 is rotated by the sub-shaft 16, so the pin 25 of the crank member 24, which rotates together with the shoji 2, rotates in a circular arc from the position S in the direction of the arrow f, centering on the position R of the sub-shaft 16. It rotates 180°-α0, reaches b□, and stops.

Similarly to the above, an arc guide groove in which the pin 25 moves from S to bIK is bored in the side plate 6 of the window frame fitting A so as to be continuous with the guide groove a.

Next, the brake device that controls the rotation of the bearing fitting B is as shown in FIG. A metal friction plate 31a is interposed in the middle, and this is sequentially inserted into the main shaft 11.

- of the metal friction plate 31a is formed with a right-angled portion 31c,
When inserted into the main shaft, its rotation is prevented by the hanging wall 8 of the side plate 6 and a protrusion 10 parallel to the main shaft 11 extending from the hanging wall 8 of the side plate 6.

Next, on the opposite side of the bearing fitting B, that is, the side where the main shaft 11 protrudes from the bearing hole 18 of the bearing fitting B, Bakelite and metal friction plates 30 c and 3 l b of the same shape as above are inserted, and the holding fitting 32 is inserted. Screw the screw 33 into the threaded portion 12 at the tip of the main shaft 11 through
It is configured to apply a brake to the rotation of the

Due to the diagonal configuration, when the shoji 2 is in the closed position shown in FIG. Its rotation is controlled.

In addition, the subshaft 16 of the shoji side metal fitting C fixed to the shoji 2 is inserted into the bearing part 20 of the U-shaped bearing structure 19 at the upper part of the bearing metal fitting B. 11
．． It is supported by the window frame 1 via a window frame side metal fitting A.

When the locking device (not shown) is unlocked when the shoji 2 is in the closed position as shown in FIG. As shown in FIG. 2, the pin 25 of the inserted crank member 24 slides only in the guide grooves a of circular arcs a and S around the main shaft 11, that is, P, so that the crank member 24 The auxiliary shaft 16 that is integrated with the auxiliary shaft 16 does not rotate around Q, but rotates from Q to RE around P.

That is, it rotates together with the bearing fitting B, rotates through the intermediate position shown in FIG.
comes into contact with the lower part 26 of the hanging wall 8 of the window frame side metal fitting A and stops at the position shown in FIG.

Next, when this shoji 2 is further rotated from this natural ventilation position, since the bearing fitting B cannot be rotated, the center of rotation is shifted to the sub-shaft 16, and the shoji 2 is moved to the R position, that is, the seventh position around the sub-shaft 16. After passing through the horizontal position shown in the figure, it rotates 180 degrees as a whole and stops at the position shown in Figure 8, that is, the position where the outer glass surface of the shoji can be cleaned indoors.

During this time, the pin 25 of the crank member 24 is configured to move within the guide groove from S to bo centering on R, which is the natural ventilation position of the subshaft 16, so that the shoji 2 smoothly moves 180 degrees centering on R. It can rotate by 0°-α0.

Next, when returning the shoji to its original position, pull the lower part of the shoji 2 toward you in the opposite direction to the above and push it up at the position of the shoji 2 shown in Figure 8. Pin 25 of 24 moves from bl to S.

That is, the shoji 2 returns to the natural ventilation position shown in FIG. 6 after passing through the positions shown in FIG. 8 and FIG. 7.

From this natural ventilation position, the pin 25 of the crank member 24 is limited to moving within the guide groove a centered at P, so the subshaft 16 integrated with the crank member 24 is centered at R. It does not rotate as such, but always rotates around P.

In other words, it rotates together with the bearing fitting B, passes through the position shown in Figure 5, rotates in the exact opposite direction to the open position, and then moves to the fourth position.
The shoji can be returned to the closed position shown in the figure.

The subshaft 16 returns from the R position to the Q position.

As described above, the axis device of the horizontal rotating window of the present invention can stop the shoji from the closed position at the natural ventilation position, for example at an angle of α.

Also, during this time, the shoji 2 can be stopped at any desired release angle using the brake device.

Furthermore, it is further removed to the cleaning position of the outer glass surface of the shoji 2 [180
'-α0, that is, the whole can be rotated by 180 degrees.

During this time, the guide groove a [Therefore, the shoji 2 is rotated α together with the bearing fitting B, temporarily stopped at the natural ventilation position, and the guide groove 1) [therefore, the shoji 2 is reliably rotated 180° - α0, that is, 1800 times in total. The outer glass of the shoji 2 can be moved to a position where it can be safely cleaned indoors.

In this device, a pin 25 of a crank member 24, which has a simple structure and is attached to a subshaft, is inserted into a groove a.

To guide the inside of b, that is, to move the pin 25, al-
By limiting to s-b, the shoji 2 is closed → opened →
It is a shaft device that can freely and reliably perform the rotation of the shoji leading to inversion, etc., and the reverse rotation → opening → closing. If the shoji 2 is lifted in the direction of the arrow in the natural ventilation position, the secondary shaft 16 will come off from the opening 21 of the U-shaped bearing tank 19 of the bearing fitting B, and the shoji 2 can be removed from the window frame 1. It is also equipped with
