なることがある。(Prior Art) Conventionally, in order to open and close a shoji screen and to restrict its rotation range, two or more rods R1 and R2 are conventionally installed in casement windows of this type, as shown in the drawings.
A link L, which is connected in a shape of a square or a pantograph and configured to be bendable and extensible, is mounted across the outer frame 1 of the casement window W and the swinging end of the shoji 2. However,
There is no problem with the link L as long as both ends of the link L are connected to the outer frame 1 and the shoji 2 by hinges with the same mechanism, and the rotation directions of the two hinges are symmetrical, but the power Depending on the transmission form (rotation mechanism of the input device), hinge installation conditions, etc., the penetration direction of the axis that supports both ends of the link may differ.
During the opening/closing operation of the shoji screen, a large twisting force may be generated in a part of the link L, making it difficult to smoothly open/close the window.

行ない難くなると云う問題があつた。 The drawings in FIGS. 1A to 1C show an example of the link L in which the above-mentioned torsional force is generated. In this case, the link L attached to the casement window W is connected to two rods R.
1 and R2 are connected in a dogleg shape with a pivot P, one rod R1 is connected to the outer frame 1 of the window W, and the other rod R is connected to the outer frame 1 of the window W.
2 is attached to the swinging end of the shoji 2, and the hinges 4, 5 are rotatable by changing the penetrating directions of the pivots P1, P2 by 90 degrees, respectively.
It is connected to. In such a link L,
Apply a rotational force in the horizontal direction to the hinge 4 on the outer frame 1 side as shown by the arrow, bend and stretch the link L in the order of C, B, and A to open the shoji 2, or rotate the hinge 4 in the opposite direction and open the link L. When closing the shoji 2 by bending and stretching L in the order of A, B, and C, the longitudinal axis P of the rods R1 and R2 is
Axis P1, P, P2 for 1-P and P-P2
are at right angles, so if you bend and stretch link L while always maintaining this relationship, rod R
No twist occurs in either R1 or R2. However, during the opening/closing operation of the shoji 2, the swinging end of the shoji 2 moves not in a straight line but in an arcuate trajectory. →In the process of transitioning to state C, when the hinge 4 on the outer frame 1 side is rotated to the left or right, an upward force acts on the tip of the rod R2 when opening the shoji 2, causing the shoji 2 to open. Conversely, when closing, a downward force acts on the tip of the rod R2. At that time, the two pivots P2 and P that support the rod R2 on the shoji 2 side always have the same penetrating direction, so while always maintaining a parallel state, they immediately respond to the inclination of the shoji 2 and are perpendicular to the axis P-P2 of the rod R2. Since the rod R2 on the shoji 2 side does not twist, the rod R1 on the outer frame 1 side that is connected to this rotates in the horizontal direction with the pivot P1 of the hinge 4 on the same plane. However, the direction of the pivots P and P1 that support the rod R1 on the outer frame 1 side is not the same as that originally stated. As a result, a torsional force is generated between the pivot shafts P and P1 of the rod R1, as shown in FIG. The amount of twist becomes maximum when the hinge 4 rotates 45 degrees and the rods R1 and R2 are bent by about 90 degrees, which prevents the link L from smoothly bending and extending. As a means to prevent such a phenomenon from occurring, the through hole H of the pivot P that connects the rod R1 on the outer frame 1 side and the rod R2 on the shoji 2 side is formed to be much larger than the diameter of the pivot P. However, a method can be considered in which the torsion is absorbed by the play that occurs between the pivot P and the through hole H, but in reality, if a large play is provided in the penetrating portion of the pivot P as described above, the link L There is a problem in that the overall bending/extension movement becomes unstable, which not only causes malfunctions but also makes it difficult to open and close the window smoothly and reliably.

When opening and closing the entire hinge 4 on the outer frame 1 side in the direction shown by the arrow, the link L bends and stretches as shown by the chain line in FIG. When the hinge 4 is rotated in the opposite direction, the shoji 2 is closed to its original state. The twist that occurs in the rod R1 is different from the conventional case.
Since there is a rotatable connecting part in the middle part of the
The rods r1 and r1' are divided into two bodies at this part.
Of these, the rod r1' on the tip side rotates in the direction shown by the arrow and absorbs the twisting that occurs in the rod R1 on the outer frame 1 side, so that the rod R1 on the outer frame 1 side does not twist when the link L bends and stretches. There is no deformation, and the shoji can be opened and closed smoothly and without strain at all times.
