Description

[Detailed description of the invention] (Industrial application field) This invention is to automatically stop the shoji at a predetermined opening angle such as 30 degrees, or to fully open the shoji regardless of the above predetermined angle. The present invention relates to a vertical axis window provided with a halfway opening stop / release device.

(Conventional technology) Conventionally, in a window in which a sliding door is opened and closed by a vertical axis on a window frame, in order to keep the sliding door halfway open, an arm is swingably connected to the window frame near the vertical axis. Has a configuration in which a pin that engages with the arm is protruded, the engagement hole is formed in a long hole, and a cutout portion is provided for the pin to engage with the long hole when the sash is opened halfway.

(Problem to be Solved by the Invention) In the window having the above configuration, the arm is fixed by the notch of the arm and the pin of the sash, and the sash is held halfway. Therefore, when the shoji is opened, the shoji will always stop at the halfway opening, or will be opened at once without any special operation of stopping,
In the case of having a mechanism that stops halfway, there is a disadvantage that it cannot be fully opened when it is necessary to open all at once, and conversely, in the case of having a mechanism that passes by, there is a disadvantage that it cannot be stopped halfway. Further, in order to release the halfway opening, it is necessary to perform a troublesome operation in which the notch must be removed from the pin by operating the arm.

In particular, according to the mechanism that stops halfway, in the case of a window that is also used as an emergency exit, when you want to open the window from the outside at once to rescue from outside, even if there is an external handle, as described above, smoothly There was a problem that the rescue operation was hindered because it could not be fully opened.

In view of the above situation, the present invention
The handle can be opened and released halfway by the handle operation, as well as fully open and closed, and from the outside,
An object of the present invention is to provide a longitudinal aperture window provided with a halfway opening stop / release device that can be fully opened and halfway opened by operating a handle.

(Means for Solving the Problems) That is, according to the present invention, the reference numerals used in the embodiments are attached and described. A sliding body 24 movably mounted; an arm 18 having one end pivotally attached to the window frame F and the other end pivotally attached to the sliding body 24; and a sliding guide surface when the sliding body 24 moves. In addition, a base 23 having a hole 26 at an appropriate position, a pin rear end 30b is provided so as to be able to protrude and retract from the hole 26, and the pin rear end 30b does not always enter the hole 26 by a spring 34. A pin 30 that is elastically biased in the direction, and is movably mounted in the horizontal frame, and a slope 41 is provided at a suitable position, and the slope 41 is a tip end of the pin 30.
A sliding bracket 33 for moving the pin 30 in the direction of the hole 26 by sliding contact with 30a; a handle rotatably provided on the window frame F; A cam 53 and a pin 54 for converting to reciprocal movement; andthe sliding body 24 further includes a pin 27, and a spring 28 for elastically biasing the pin 27 in the direction of the hole 26. Reference numeral 27 denotes a longitudinally extending window provided at a position where the tip of the sliding member 24 can move in and out of the hole 26 with the movement of the sliding member 24.

(Operation) When the sliding door S is opened and closed, the sliding body 24 pivotally attached to the other end of the arm 18 slides in the horizontal frame of the sliding door S.

Since the pin 27 is always elastically urged by the spring 28, the tip of the pin
Into the hole 26 at the position of the hole 26. By the fitting of the pin 27 and the hole 26, the sliding body 24 is restrained, so that the rotation of the sash S is stopped halfway and locked at that position.

On the other hand, when the handle is turned to move the slide fitting 33 and the pin tip 30a is slid on the slope 41 to press the pin 30, the pin rear end 30b is fitted into the hole 26, and the pin of the slide 24 is inserted. Two
7 is pushed out of the hole 26. If the pin 27 and the hole 26 are disengaged from each other, the lock of the sliding body 24 is released, and the sash S can be turned again.

Also, from the beginning, the handle is turned as described above to move the slide fitting 33, and the pin rear end portion 30b is fitted in the hole 26 in advance, so that the pin 27 of the sliding body 24 matches the hole 26. ,pin
Since 27 does not fit into hole 26, the movement of sliding body 24 is not restricted. Therefore, since the rotation of the shoji S is not restricted, the rotation of the shoji S is not stopped halfway and locked at that position, and the shoji S can be fully opened smoothly.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

The base 23 has a hole 26 near the tip, and the slide 24 has a hole 26
In the normal state in which the sliding door S is closed, the tip of the pin 27 is pressed against the base 23 in a normal state where the shoji S is closed. .

For example, FIG. 5 shows a state in which the sliding door S is closed, and the pin 27 is pressed against the base 23 by a spring 28 at a distance from the hole 26 to the left.

The release mechanism B, as shown in FIG.
And a sliding fitting 33 for pushing the holding fitting 32 and the pin 30 into the hole 26. Also, the holding bracket 32 and the case
16a is integrally connected by a base 37, the base 37 is incorporated into a hole provided in the indoor wall of the lower frame 5, and the base 37 is provided with a hole 39 through which the pin 30 passes. In addition, holding bracket 32
Are combined so that the sliding bracket 33 can be moved only to the left and right.

The holding bracket 32 has a pin 30 in the center, and the pin 30
Is biased by a spring so that the rear end portion 30b projects from the outdoor surface. That is, when the rear end portion 30b protrudes, the front end portion 30a is retracted. The holding bracket 32 is provided with a pair of left and right long holes 35,35.

Regarding the shape of the sliding bracket 33, a portion other than the left end portion 33a is formed in a U-shaped cross section to be combined with the holding bracket 32, and includes a sliding wall 38 joined to the outdoor surface of the holding bracket 32. The sliding wall 38 is provided with a release hole 40 into which the tip portion 30a of the pin 30 falls, and the release hole 40 has a slope 41 with a clearance angle to the right with respect to the pin 30 on the left inner surface. The sliding bracket 33 has a base portion 33a with a driving pin 42 and a driving body 44.

The driving body 44 has a base rod 51 connected to the left of the central rod 50 and a front rod 52 connected to the right (FIG. 7). The mechanism for moving the driving body 44 left and right includes an external handle 12. The cam 53 is attached to the shaft 15 of the
By forming a long hole 55 in 53 and projecting a pin 54 that engages with the long hole 55 at the protrusion of the central rod 50, the outer handle 12 or the inner handle 13 is lifted, thereby 44 is moved to the right and vice versa. The driving body 44 is provided with a slot 57.
Is connected to the interlocking base rod 9 by engagement of the
When the sliding door S is closed and locked, the pin 56 is positioned at the left end of the slot 57.

Further, in the embodiment, an opening and fixing mechanism D for holding the sash S in a 90-degree opened state by associating the adjuster 16 with the arm 18 is provided. Specifically, a vertical pin 47 with a release button 46 is attached to the base end of the adjuster 16 by urging downward with a spring, and the vertical pin 47 falls into the sliding body 24 pivotally attached to the arm 18. A drop hole 48 is provided.

To open the above-described sliding door S of the vertical axis opening window from the closed state, one of the locking handle 10, the outer handle 12, and the inner handle 13 is operated.

First, a case where the locking handle 10 is operated will be described.

When the locking handle 10 is lifted, the ratchet 20 is disengaged from the window frame F and the locking is released. At the same time, interlocking mechanism C
Although the interlocking base rod 9 at the end of the right side moves rightward, the driving body 44 is not affected by the slot 57. Therefore, when the sliding door S is opened 30 degrees, the sliding body 24 moves rightward, so that the pin 27 falls into the hole 26, and the shoji S is stopped and held halfway open at a predetermined angle. That is, the locking handle 10 is operated to open the shoji S halfway.

Next, to unlock this 30 degree opening, use the internal handle 13
(Or external handle 12). Then, the sliding bracket 33 is moved rightward by the driving body 44 (two-dot chain line in FIG. 5). At this time, the slope 41 of the release hole 40 pushes the tip 30a of the pin 30 to reduce the elasticity of the spring 34. Against the rear end 3
0b protrudes into the hole 26, protrudes the pin 27 from the hole 26, and the stopped state is released. In other words, the shoji screen S can be closed and can be opened at 90 degrees.

Next, the outer handle 12 or the inner handle 13 is lifted in order to open the sliding door S at once by 90 degrees from the closed state through the halfway open state. With this operation, the pin 56 of the interlocking base rod 9 is pulled to the right in the slot 57, and the ratchet 20 is pulled.
Is released from the window frame F, and the lock is released. Simultaneously with the release of the lock, the slide fitting 33 moves to the right, and the hole 26 is closed by the rear end 30b of the pin 30. In this state, the sliding door S is pushed open, and the sliding body 24 is moved rightward.
Even if reaches the position where the hole 26 exists, it does not fall into the hole 26 but passes through. That is, the sliding door S can be smoothly opened all at once to 90 degrees.

When the sliding door S is opened up to 90 degrees, the sliding body 24 reaches the right end of the adjuster 16, so that the vertical pin with the button 46 at that position is provided.
47 falls into the drop hole 48, and the pivot pin 25 of the arm 18 is fixed. That is, the sliding door S is fixed at an opening angle of 90 degrees.

In this state, since the rear end portion 30b of the pin 30 is pressed against the sliding wall 38 of the sliding bracket 33 by the spring 34, the friction generated mainly between the pin 30 and the sliding wall 38 causes 33
Is prevented from moving to the left, and the raised state of the outer handle 12 and the inner handle 13 is maintained. Therefore, the outer handle 12 and the inner handle 13 may be left as they are. That is, in this state, the rear end 30b of the pin 30 closes the hole 26, and when the sliding body 24 moves to the left,
Since 27 passes through the hole 26, the shoji S is closed at once without stopping the shoji S halfway.

In this state, the slot 57 of the driving body 44 shifts to the right,
Since the pin 56 is located at the left end of 57 (two-dot chain line in FIG. 8), when the shoji S is closed and the inner handle 10 is pushed down, the driving body 44 is pulled to the left by the pin 56, so that the outer handle 12 And the internal handle 13 are lowered at the same time,
At the same time, the sliding bracket 33 moves to the left, the tip 30a of the pin 30 falls into the release hole 40, and the tip 30b comes off the hole 26, thereby returning to the initial locked state.

(Effects of the Invention) As described above, according to the present invention, the shoji can be stopped halfway open suitable for ventilation, and can be easily released by operating the handle. Sometimes, it can be operated without resistance because it does not stop on the way, and even when opening the shoji fully open, it can be opened all at once by operating the steering wheel, so the midway stop and release of the shoji, The door can be fully opened and closed only by operating the steering wheel in the room, and from outside the door, the shoji can be opened at once by the handle, which is advantageous in that it is convenient for rescue from the outside in an emergency.
