[Conventional technology]

As a conventional device of this type, a stopper device disclosed in Japanese Utility Model Publication No. 14700/1983 is known. Where,
The guide frame attached to the window frame and the rotating window are connected by a check arm to regulate the amount of opening of the rotating window to the extent that ventilation can be performed. The guide frame is provided with a vertically elongated guide groove, and the restraining arm and the guide frame are connected by a pin that moves along the guide groove. In order to hold and fix the pin in the above-mentioned restricted position, a stop lever is provided inside the guide frame, and the stop lever is biased to swing by a spring. The stop lever can be operated to release the stop by using a knob provided on the outer surface of the guide frame against the spring. In this released state, the pin is moved to the upper end of the guide groove, and then pulled out from the large diameter hole provided at the end of the groove to open the window. can be fully opened.

[The problem that the idea aims to solve]

In the above-mentioned stopper device, the knob for switching and operating the stop lever is provided on the outer surface of the guide frame so as to be exposed at all times, so it is susceptible to tampering.

To fully open the window, it is necessary to push the window open with the knob released, move the pin to the top of the guide groove, and then operate the check arm to pull the pin out of the guide frame. The operations and procedures are cumbersome. Particularly in chaotic situations during emergencies, it is not possible to fully open the windows quickly.

The purpose of this invention is to provide an opening amount regulator that is less susceptible to tampering and that can fully open the window by releasing the connection between the check member and the window with a single touch in the event of an emergency such as a fire.

[Means to solve the problem]

The opening amount adjuster of this invention includes a check member 7 whose one end is connected to the window frame 2 via a fixture 8, and a restriction release means 9 which is attached to the window 4 and whose other end is connected to the check member 7. One end of the check member 7 is connected to the restriction release means 9 via a connecting pin 11, and the restriction release means 9 includes an insertion hole 38 into which the connection pin 11 is inserted and engaged. a main case 33, and a slide frame 34 supported within the main case 33 so as to be slidable between a standby position and an engagement release position along a direction intersecting the central axis of the connecting pin 11.
and includes an operating member 25 whose one end is fixed to the slide frame 34 and whose other end protrudes to the outer surface of the window 4, and a return spring 37 which biases the slide frame 34 toward the standby position. A keyhole-shaped lock hole 39 is formed in the face wall of the slide frame 34, which engages with the engagement groove 20 formed at the tip of the connecting pin 11 in the standby position, and allows the connecting pin 11 to come out in the disengaged position. The outer surface of the operating member 25 is attached to the pressing surface 3 attached to the window 4.
1. When the slide frame 34 is slid to the disengagement position, the connecting pin 11 is inserted into the main case 33.
It is required that a kick-out spring 35 for kicking out the main case 33 is provided inside the main case 33.

[Effect]

In a normal state, the opening amount regulator regulates the opening amount of the window 4 to such an extent that the check member 7 is fully extended and ventilation can be performed. In this ventilated state or with the window 4 closed, the operating member 25 is covered with the cover 26, so that the operating member 25 can be prevented from being manipulated by mischief.

In an emergency, the push-split surface 31 of the cover 26 is broken and the operating member 25 is pushed or pulled against the biasing force of the return spring 37. Then, the slide frame 34 is displaced and the position of the lock hole 39 provided in its face wall is changed, allowing the connecting pin 11 to come out. At the same time, the connecting pin 11 is forcibly pushed out of the main case 33 by the kick-out spring 35 provided inside the main case 33, so that the engagement state between the check member 7 and the main case 33 is released. , window 4 can be fully opened. In other words, with one-touch operation, the restraining member 7 can be
can be unlinked.

[Effect of idea]

In this invention, the restriction release means 9 attached to the window 4
and the window frame 4 are connected by a restraining member 7 to regulate the opening amount of the window 4 to the extent that ventilation can be performed, and in an emergency, after destroying the press-split surface 31 of the cover 26,
By simply pushing and pulling the operating member 25, the restraining member 7
and the connection state of the restriction release means 9 can be released. Therefore, in an emergency, the opening restriction by the check member 7 can be canceled with a single touch, the window 4 can be fully opened quickly, and the window opening can be secured as an evacuation exit. Furthermore, since the outer surface of the operating member 25 is covered with the cover 26, it is possible to prevent as much as possible the operating member 25 from being manipulated and the window 4 being fully opened by a mischievous person in normal use.

When the slide frame 34 slides to the disengagement position, the disengagement hole 40 is located on the outer surface of the engagement groove 20, allowing the connecting pin 11 to come out and come off.

The side wall of the spring frame 36 facing the lock hole 39 has a rectangular notch, and the kick-out spring 35 is fixed to the spring frame 36 with its free end facing the notch. The kick-out spring 35 is made of a leaf spring, and is bent into a F-shape when viewed from above, and when connected, the kick-out spring 35
The free end side of the connecting pin 11 is pressed against the inner end of the shaft portion 19 of the connecting pin 11 .

Next, the operation of the opening amount regulator 1 will be explained separately in a normal state and an emergency state.

Under normal conditions, the window 4 can be opened only between the closed state shown by the imaginary line in FIG. 1 and the ventilation open position shown by the solid line in FIG. In the closed position, the check member 7 is housed between the vertical frame 4a of the window 4 and the guide frame 8, as shown in FIG. The check member 7 moves downward along the window 4 and is pulled out to the indoor side along with the window 4. When the connecting pin 10 descends to the lower end of the guide groove 16, the restraining member 7 cannot be pulled out any further, so that the window 4 is prevented from swinging open and the window 4 is opened to the extent that ventilation is possible (specifically, the opening interval is about 8 cm). Opening amount is regulated.

In this state, the restraining member 7 also functions as a fan stopper for the window 4. For example, even if a force in the closing direction is applied to the window 4, the connecting pin 10 is held in the notch 18 at the lower end of the guide groove 16. Therefore, connecting pin 1
0 will not return upward along the guide groove 16, and the window 4 will not close due to the wind or the contact force of the human body against the window 4. When the restraining member 7 is lifted and the connecting pin 10 is moved into the guide groove 16, the window 4 can be closed.

In an emergency, the operating member 25 is operated by pushing the split surface 31 of the cover 26 as shown in FIG. Simultaneously with the pushing of the operating member 25, the slide frame 34 and the spring frame 36 move in the same direction as the operating member 25 against the return spring 37. Due to this movement, the lock hole 39 also moves, and until then the connecting pin 1
The engagement hole 41 that was fitted into the engagement groove 20 of No. 1
comes out of the engagement groove 20, and the release hole 40 is located outside the circumference of the engagement groove 20. At the same time, the kick-out spring 35 also moves together and rides on the inner end surface of the connecting pin 11.
The connection pin 11 is ejected at the same time that the release hole 40 is located outside the circumference of the engagement groove 20.

As a result, the connecting piece 14 is separated from the window 4, and the window 4 is released from restraint by the restraining member 7, so that it can be opened to the fully open position. This separation operation is performed on Windows 4
This can be done even when the is in the closed position. This is why the connecting pin 11 is located below the guide frame 8 in the closed position shown in FIG.

If you want to restrict the opening amount of window 4 again, connect pin 1.
1 into the lock hole 39 of the slide frame 34 to connect the connecting piece 14 and the restriction releasing means 9, and then the cover 26 is replaced.

[Second Embodiment] FIGS. 7 and 8 show a second embodiment of the present invention.

In FIG. 7, the check member 7 is formed of two bendable arms 13a and 13b in the shape of a folded scale,
One arm 13a is connected to the window frame 2 via a connecting pin 10 and a bracket 45 (attachment). The connecting pin 10 supports the arm 13a swingably and tiltably in the thickness direction of the arm 13a. Both arms 13 are connected to the connecting portion of both arms 13a and 13b.
A claw piece 46 is folded up to prevent downward bending of a and 13b.

The connecting pin 11 on the window 4 side consists of a connecting plate 47 that is rotatably caulked and fixed to the arm 13b, and two connecting pins 48, 48 that are fixed above and below the plate surface of this connecting plate 47. Engagement grooves 20, 20 are provided in the connecting pins 48, 48. Slide frame 34
is formed into an L-shaped cross section, and a push-button-shaped operating member 25 is fixed to one wall surface thereof. Lock holes 39, 39 are provided in the other wall surface in correspondence with the pair of connecting pins 48, 48 mentioned above.

Kick-out pins 49, 49 that abut the connecting pins 48, 48 are supported in the main case 33 of the kick-out mechanism 22 so as to be movable in the axial direction.
are pushed into the kick-out position by kick-out springs 35, 35 made of compression coil springs. The rest of the configuration is basically the same as the first embodiment.

[Third Embodiment] FIG. 9 shows a third embodiment of the present invention in which the check member 7 is changed. In this case, the restraining member 7 is provided with restricting protrusions 50, 50, which come into contact with each other and restrict the bending direction, at the intermediate connecting portion, respectively.

By providing the limiting protrusions 50, 50 in this way, even if an external force in the direction of closing the window acts on the restraining member 7 when the ventilation is opened, the protrusions 50, 50 butt against each other and the window 4
This is effective in preventing wobbling because the rod does not repeatedly swing with small strokes.

The opening amount regulator 1 is applicable regardless of the opening direction of the window 4, such as opening inward or outward, or tilting inward or outward. This applies to all other types of swing windows.
