Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a sash in which a shoji is opened by being rotated about a vertical axis. 2. Description of the Related Art In this type of sash, an opening angle adjusting arm is provided between a lower frame and a lower frame of a vertical sliding sash.
It is known that a shoji is fixed at a predetermined opening angle. The opening angle adjusting arm supports the lower frame of the shoji in a horizontal direction with respect to the lower frame when the shoji is opened. [0003] However, there is no support between the upper frame and the upper frame, which supports the shoji in the horizontal direction, and it is in a free state. For this reason, if the sash is subjected to wind pressure while the sash is open, there is a possibility that the top and bottom of the sash will be twisted. Accordingly, an object of the present invention is to provide a sash in which a shoji can be opened and closed by rotation with respect to a vertical axis, and an object of the present invention is to prevent the shoji from being twisted in an open state. According to a first aspect of the present invention, there is provided an opening angle adjusting arm for adjusting an opening angle of a shoji, wherein the shoji is rotatably mounted on a sash frame by a vertical axis, and a shoji is provided. With a buffer arm to soften the opening and closing operation of
The opening angle adjusting arm is attached between the lower frame and the lower frame, and has an operation unit for fixing the sliding door at an arbitrary opening angle, and the buffer arm is a cylindrical member fixed to one of the upper frame or the upper frame. And a rod-shaped member fixed to the other of the upper frame or the upper frame, wherein the rod-shaped member is capable of moving forward and backward in the cylindrical member while receiving frictional resistance with the cylindrical member. According to the first aspect of the invention, when the shoji is opened, the shoji is rotated by a predetermined angle about the vertical axis, and the operating section is operated at an arbitrary rotation angle to fix the shoji. If the shoji receives wind pressure during the opening / closing operation of the shoji, the shock-absorbing arm prevents the shoji from rotating rapidly. In the open state of the sash, when the sash is subjected to wind pressure, the lower end of the sash is supported horizontally by the opening angle adjustment arm, and the upper end of the sash is supported by the buffer arm in the horizontal direction. Since there is a horizontal support, it is possible to prevent twisting up and down of the shoji. In addition, since the opening angle adjusting arm that requires operation is located between the lower frame and the lower frame, and the buffer arm does not require operation, the usability is not impaired. Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view of a sash according to an embodiment of the present invention, FIG. 2 is a plan view showing a mounting portion of an opening degree adjusting arm in an open state of a shoji, and FIG. FIG. 4 is a plan view showing a mounting portion, FIG. 4 is a longitudinal sectional view of a buffer arm, and FIG. 5 is a front view of the sash shown in FIG. Sash 1 according to the present embodiment
Is a vertical sliding window, which is attached to a sash frame 7 by hinges 5 and 6 provided on the upper and lower sides of a shoji,
Are rotated outward about a vertical axis (vertical axis) that moves outward and open. An opening angle adjusting arm 13 is provided between the lower frame 9 and the lower frame 11. The opening angle adjusting arm 13 includes a rail member 15 attached to the lower frame 11 of the shoji 3 and an arm member 17 rotatably attached to the lower frame 9. , 19 to the lower frame 11. The rail member 15 is a prism having a square cross section, and an engagement hole 21 is provided at a position corresponding to a predetermined opening angle of the shoji. A slider 23 is provided on the rail member 15 so as to be slidable in the longitudinal direction of the rail member 15, and by lowering or raising the operation portion 25 of the slider 23, the operation portion 25 is engaged with the engagement hole 21 of the rail member 15. It is for engaging and releasing the engagement. Arm member 17
Has one end attached to the lower frame 9 by a frame bracket 27, and the arm member 17 is rotatable with respect to the frame bracket 27. The other end of the arm member 17 is the slider 2
3 is connected rotatably. Here, hinges 5, 6
Will be described. The lower hinge 6 is attached to the lower frame 11 and the lower frame 9, and the upper hinge 6 is connected to the upper frame 27 and the upper frame 29.
It is attached to. The hinges 5 each have six bars A
To F to form a link, and the bar F is a lower frame 9
Are movable along the longitudinal direction. The hinge 6 has the same configuration, and the bar F of the hinge 6 is movable along the longitudinal direction of the upper frame 29. A buffer arm 31 is provided between the upper frame 27 and the upper frame 29. The shock-absorbing arm 31 includes a cylindrical member 33 and a rod-shaped member 35 provided in the cylindrical member 33 so as to be able to advance and retreat. One end 33a of the cylindrical member 33 is rotatably attached to the upper frame 29. One end 35a of the member is rotatably attached to the upper frame 27. The shock absorbing arm 31 uses frictional resistance to moderate the movement of the rod-shaped member 35. In the present embodiment, the cross section is substantially elliptical, and a commercially available product manufactured by Suko Japan is used. The buffer arm 31 includes a cylindrical member 33 and a rod-shaped member 35. The cylindrical member 33 includes a cushion member 37, a stop fitting 39, a friction resin 41,
The fastener 43 is stored. The rod-shaped member 35 can move forward and backward in the cylindrical portion 33 together with the stopper 45, and receives frictional resistance when moving forward and backward by a friction member 41 provided between the rod-shaped member 35 and the cylindrical member 33. Next, the opening and closing of the sash 1 according to this embodiment will be described. When the shoji 3 is opened, the upper and lower hinges 5 and 6 rotate the shoji 3 outward about a vertical axis. Then, for each predetermined opening angle (for example, 15
, 30 degrees, 90 degrees), the operation part 25 is lowered to be locked in the engagement hole 21 of the rail member 15,
By fixing the slider 23 to the rail member 15,
The opening angle of the shoji 3 is fixed. When changing the opening angle of the shoji 3 or closing the shoji 3, the operation unit 25 is operated so as to be lifted, and the slider 23 and the rail member 1 are operated.
5 is disengaged so that the shoji 3 can rotate freely. On the other hand, when the shoji 3 is subjected to wind pressure when opening or closing the shoji 3 or during the opening / closing operation, the buffer arm 31 prevents the abrupt rotation of the shoji 3, so that the shoji 3 opens and closes rapidly. Can be prevented. When the shoji is subjected to wind pressure with the shoji 3 opened at a predetermined angle,
Opening angle adjusting arm 13 provided on lower frame 11 of shoji 3
And the buffer arm 31 provided on the upper frame 27 supports the horizontal direction (opening direction) above and below the shoji screen 3,
This prevents the shoji 3 from being twisted by wind pressure. The present invention is not limited to the above embodiment,
Various modifications can be made without departing from the spirit of the present invention.
For example, the buffer arm 31 may be configured such that the tubular member 33 is attached to the upper frame 27 and the rod-shaped member 35 is attached to the upper frame 27. The sash 1 of the present invention is not limited to the outer vertical sliding window, but may be an external window or a vertical axis rotating window. According to the first aspect of the present invention, the abrupt rotation of the shoji can be prevented by the buffer arm 31 when the shoji receives wind pressure during the opening and closing operation of the shoji. In the open state of the sash, when the sash is subjected to wind pressure, the opening angle adjusting arm at the lower end of the sash and the buffer arm at the upper end of the sash support the horizontal direction, so that the torsion occurs at the top and the bottom of the sash. Can be prevented. The opening angle adjusting arm that requires operation is located between the lower frame and the lower frame, and the buffer arm does not require operation, so that the usability is not impaired.
