Description

[Detailed Description of the Invention] This invention relates to a device for regulating the opening angle of a shoji screen incorporated in a casement window or a vertical rotating window.

Traditionally, this type of window has been frequently used in high-rise buildings, but if it is used by an unspecified number of people, allowing it to open without permission may cause an unexpected accident, so it should not be opened at more than a certain angle. are restricted from opening. On the other hand, when cleaning the outer surface of the glass of a shoji while indoors, the user must rotate the shoji and swap the outer and inner surfaces. Therefore, for safety reasons, to prevent the shoji from opening more than a certain angle, separate stop parts are provided and fixed with screws or locked, and these can be removed when necessary to prevent the shoji from opening beyond a certain angle. The solution was to increase the rotation angle, but the operation method was cumbersome and caused various problems in use.

This invention attempts to improve the drawbacks of the conventional ones, and utilizes the conventional opening angle adjustment device used in the window. An operating section is attached to a position where the user cannot notice, and by pushing up the operating section, a large rotation angle can be obtained until the outer surface of the shoji is turned toward the inner surface.

To explain this in an embodiment shown in the drawings,
In FIG. 1, A is a vertical rotating window, B is a sash frame, and C is a shoji screen. This satsushi frame B
The support 1 attached to the lower frame 18 constituting the lower frame 18 is formed in a cylindrical shape, and the bracket 2 is fixed to the indoor vertical wall 19 of the lower frame 18 together with a reinforcing plate 28.
This support 1 is rotatably attached through a horizontal through hole 17, into which the arm 3 is slidably inserted. Further, the support 1 is provided with a vertical through hole 20 that communicates with the through hole 17, and the locking rod 15 is inserted into the through hole 20 so that its lower end 14 projects into the through hole 17. By winding the coil spring 16 housed in the central enlarged portion 21 of the through hole 20 around the locking rod 15 and engaging the coil spring 16 with the collar 23 of the locking rod 15, the locking rod 15 is pressed down and its lower end 14 is held so as to protrude at all times.

A knob 22 is provided at the upper end of this locking rod 15, and by picking it up, the locking rod 15
The lower end 14 of is drawn into the through hole 20.

The arm 3 shown in FIG. 3 is formed of a hollow elongated member, and has a bracket 4 rotatably connected to one end thereof, and this bracket 4 is attached to the lower sill 24 of the shoji.
The arm 3 is attached to the shoji C by attaching it to the indoor surface of the shoji C. On the upper surface of this arm 3, when the shoji C is opened, the locking rod of the support 1 is attached when the opening can be opened at an angle that does not cause danger (for example, 30 degrees, position C ₂ in Figure 6). The first locking hole 12 is located at the position where the first locking hole 15 is inserted, and the first locking hole 12 is at a sufficient angle (approximately 135 degrees, the sixth
When the shoji C is rotated to the position ₍₃ position in Figure C), the second locking hole 13 is drilled at a position into which the locking rod 15 of the support 1 can be inserted.

The first and second locking holes 1 in FIG.
A first locking hole 1 is provided on the lower surface of the arm 3 between 2 and 13.
A rectangular hole 10 is provided on the second side, and the locking body D projects from this hole 10.
This locking body D has a plate spring 11 having a pair of engagement wings 25, 25 fixed to the upper surface of the base portion 7, which is slightly larger than the hole 10, and a plate spring 11 having a shape that can be fitted into the hole 10 on the lower surface. It is made up of a series of locking portions 8, and the side edge of the locking portion 8 facing the second locking hole 13 is formed as an inclined surface 9.

The locking body D is inserted in a compressed state into the hollow part of the arm 3 from the end on the second locking hole 13 side, and
At the position where the locking part 8 is fitted into the hole 10, the elastic force of the leaf spring 11 holds the locking part 8 so that it always protrudes downward from the hole 10.

Note that the open end of the arm 3 on the second locking hole 13 side is closed with a blind plate. Further, a pin-shaped stopper 6 is fixed to this end portion to prevent the arm 3 from accidentally coming off the support 1. Therefore, as shown in FIG. 4, when the locking rod 15 of the support 1 is fitted into the first locking hole 12, the hole 1
The locking portion 8 that protrudes from the 0 is located near the mouth edge of the through hole 17 of the support 1, and in the unlikely event that the locking rod 15
Pull up and remove it from the first locking hole 12, and then remove the arm 3.
Even if an attempt is made to open the shoji B further by sliding the shoji B, the protruding locking member locking portion 8 comes into contact with the mouth edge of the through hole 17, that is, the side wall of the support 1, preventing further sliding of the arm 3. prevent.

Since this locking portion 8 protrudes below the arm 3 to a position out of sight, a person who is unaware of the existence of the locking body D cannot open the shoji C any further.

On the other hand, when cleaning the outer surface of the glass is required, when the locking part 8 of the locking body D is pushed up against the elastic force of the leaf spring 11, the locking part 8 is recessed into the hollow part of the arm 3. Therefore, the arm 3 can further slide through the through hole 17 of the support 1, and can rotate until the outer surface of the glass faces toward the indoor side. When the shoji C is rotated to the maximum angle (approximately 135 degrees), the locking rod 5 of the support 1 fits into the second locking hole 13 of the arm 3, so that the shoji C can be stopped at that position. In addition, the locking body D is, for example, a leaf spring 1.
Even if the elasticity of the hole 10 becomes weaker, its own weight
Since it can protrude further, the locking operation of the arm 3 by the locking portion 8 of the locking body D remains unchanged.

Further, when the locking body D is provided on the solid arm 3 as shown in FIG. The locking portion 8 of the locking body D housed in the locking member 27 may be made to protrude. In this case, in order to prevent the locking body D from falling off, it is necessary to fix the plate 26, which has a hole 10a through which the locking part 8 can protrude, at the position where the locking part protrudes from the lower surface of the arm 3.

To return to the window closed state from the above state,
Pull up the knob 22 and insert the locking rod 15 into the second locking hole 13.
After removing the arm 3 from the
slide. The locking part 8 protruding at this time is
Although it comes into contact with the side opening edge of the through hole 17 of the support 1, since the side opposite to this opening edge is formed in the inclined surface 9, there is no need to push the locking body D into the hollow part. The locking body D is automatically retracted and passes through the through hole 17 of the support 1 in this retracted state,
Since the arm 3 can be slid, the shoji C can be returned to the closed state of the window.

In this way, by providing a locking body like a hidden button inside the arm, this device can ensure opening of vertically rotating windows, casement windows, etc., which is normally not dangerous, and also allows for a wider opening state. In this case, the locking body can be inserted into the arm to release the locking of the sliding block, and the shoji can be further rotated.The simple structure allows easy control of the opening angle. This has the effect that the device can be obtained.
