In order to reinsert the regulation pin 43 into the opening / closing cam groove 45, it is preferable to return the shoji 9 to the small opening position at a predetermined angle or to return the shoji 9 to the closed position.
Such a key member 65, an advance / retreat receiving portion 67, a fitting groove 64a, a holding frame 63, a regulation pin 43, a small opening regulation arm 42, and the like constitute an engagement / disengagement device.

The vertical sloping window 1 according to the present embodiment has the above-described configuration, and the operation thereof will be described next.
As shown in FIG. 4A, the handle 30 is located below and the slide bar 31 is located above (reference position) with the shoji 9 closed. Therefore, as shown in FIG. 8A, the narrowed convex portion 56a of the trigger member 56 is fitted into the narrowed hole portion 55b on the lower side of the hole portion 55 by the urging force of the coil spring 58, and the widened convex portion 56b It is stopped. In this state, the small opening regulation arm 42 hangs down at the closed position shown by the solid line in FIG.

From this state, the handle 30 is rotated upward in order to open the shoji 9 as shown in FIG. 4 (b). Then, the interlocking rod of the handle 30 retracts from the upper frame 3 and the lower frame 4, is pushed by the tip portion 30c, the slider 34 is interlocked downward, and moves to the lower position integrally with the slide bar 31. As a result, as shown in FIG. 8B, the hole portion 55 descends along the narrowing convex portion 56a of the trigger member 56, and the narrowing convex portion 56a reaches the position of the widening hole portion 55a. Therefore, the trigger member 56 advances by the urging force of the coil spring 58, and the widening convex portion 56b fits into the widening hole portion 55a.
As a result, the slide bar 31 is fixedly held in the lower position, and the handle 30 is also fixedly held in the upper position shown in FIG. 4 (b).

Then, when the shoji 9 is opened, as shown in FIG. 5, the small opening regulation arm 42 is pushed while sliding along the opening / closing cam groove 45 by the regulation pin 43 provided on the shoji 9, and is rotated around the rotation shaft 44. It is moved to open the shoji 9 to a small opening position. At the small opening position, the regulation pin 43 is locked at the innermost part of the terminal groove portion 45b below the opening / closing cam groove 45. The shoji 9 is held at this small opening position and cannot return to the closing direction.

Next, in order to close the shoji 9, the handle 30 is gripped with one hand, and the operating lever 50b of the release plate 50 is lowered in the opening groove 51 with the fingers of that hand. As the release plate 50 descends, the actuating pin 49 moves along the sliding guide groove 50a to project the actuating member 48. Then, as shown in FIG. 5, the operating member 48 pushes the lower end portion of the small opening regulation arm 42 to move the small opening regulation arm 42 from the locked one-dot chain line position to the unlocked two-dot chain line position. The regulation pin 43 is displaced from the innermost portion of the terminal groove portion 45b of the opening / closing cam groove 45.
As a result, the regulation pin 43 is released from the locked position of the opening / closing cam groove 45, and the shoji 9 can be closed. Since the handle 30 of the interlocking rod is locked by the trigger member 56 and the hole portion 55, the interlocking rod is held in the retracted state during the opening / closing operation of the shoji 9.

When the shoji 9 reaches the vicinity of the vertical frame 5 of the frame body 7 by the closing operation, the trigger member 56 protruding from the hole 55 of the slide bar 31 has a widening convex portion 56b at the tip of the trigger receiver provided on the metal vertical frame 5a. It comes into contact with the tapered surface 60a of the portion 60. Further, when the shoji 9 is closed, the trigger member 56 pushed by the tapered surface 60a retracts against the urging force of the coil spring 58, and the widening convex portion 56b is locked by being disengaged from the widening hole portion 55a of the hole portion 55. Is removed, and the shoji 9 reaches the closed position.
As a result, the slide bar 31 is raised by rotating the handle 30 downward from the raised position, and the interlocking rod also protrudes in the vertical direction and is locked to the upper frame 3 and the lower frame 4. In this way, the shoji 9 can be opened and closed.

Next, in order to clean the shoji 9, the shoji 9 is opened further from the small opening position, for example, at an angle of 90 degrees. Therefore, as shown in FIG. 10A, the key member 65 is inserted into the fitting groove 64a of the regulation pin adjusting portion 64 provided on the prospective surface 19ba of the handle receiving portion 19b with respect to the shoji 9 at the small opening position. To do.
After the enlarged diameter key portion 65a of the key member 65 comes into contact with the inner wall of the through hole 70 of the main body portion 43b, the key member 65 is moved 90 degrees together with the advancing / retreating receiving portion 67 in the fitting groove 64a as shown in FIG. Rotate. In this case, since the main body portion 43b does not rotate, the angle of the fitting groove 64a differs by approximately 90 degrees between the receiving surface 70a and the advancing / retreating receiving portion 67.

Then, when the key member 65 is pulled in the pulling direction, the enlarged diameter key portion 65a abuts on the receiving surface 70a of the through hole 70 and pulls the main body portion 43b against the urging force of the coil spring 68. As a result, as shown in FIG. 10 (c), the regulation pin 43 having the main body portion 43b is also pulled in and is disengaged from the opening / closing cam groove 45 of the small opening regulation arm 42. In this state, the shoji 9 can be further opened from the small opening position. Then, the shoji 9 is opened by, for example, 90 degrees to clean the frame 7 and the shoji 9.

Then, after the cleaning or the like is completed, if the shoji 9 is returned to the small opening position and the key member 65 is released, the regulation pin 43 returns to the original position by the urging force of the coil spring 68, and the regulation pin 43 is placed in the opening / closing cam groove 45. Will be inserted. After that, if the key member 65 is rotated 90 degrees, returned to the original position, and pulled out, it can be pulled out from the fitting groove 64a (see FIG. 4A).

As described above, according to the vertical sloping window 1 according to the present embodiment, the handle 30 and the operating lever 50b are in close proximity to each other when the shoji 9 has a small opening opened by a predetermined opening, so that the operator has only one hand. The operation lever 50b can be operated while gripping the handle 30. Therefore, the operation lever 50b can be operated with one hand to release the small opening regulation arm 42 from the locked position with the regulation pin 43, and the handle 30 can be used to close and operate the shoji 9.
Further, the operating member 48 regulates by pushing the lower part of the small opening regulation arm 42 separated from the rotation shaft 44 in the vicinity of the regulation pin 43 held in the innermost part of the opening / closing cam groove 45 of the small opening regulation arm 42. The pin 43 can be released from the locked position. Therefore, the force required to operate the small opening regulation arm 42 is small, and the lock can be easily released.

Further, by attaching the key member 65 to the holding frame 63 and rotating and pulling it out, the regulation pin 43 can be separated from the opening / closing cam groove 45, and the shoji 9 can be opened more greatly. Moreover, by releasing the key member 65, the regulation pin 43 can be returned to the position where it engages in the opening / closing cam groove 45 by the urging force of the coil spring 68, and the engagement / disengagement operation between the opening / closing cam groove 45 and the regulation pin 43 can be performed. Is easy. Moreover, by using the key member 65, it is possible to regulate the person who performs the engagement / disengagement operation of the regulation pin 43 from the opening / closing cam groove 45.
Moreover, since the engagement / disengagement of the regulation pin 43 and the opening / closing cam groove 45 can be switched by the key member 65, the person who operates the key member 65 is restricted and the key member 65 can be easily managed.
