Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing control device for a high smoke exhaust window, and more particularly to a structure of an operating wire winding mechanism and an emergency manual opening device.

According to Article 126-3 of the Enforcement Order of the Building Standards Act, the structure of smoke exhaust vents, that is, the high smoke exhaust windows that are the subject of discussion here, is determined.

Among these, I would like to draw attention to the following two items.

(a) A manual release device should be installed at the smoke outlet.

(D) Among the manual release devices mentioned in the previous issue, when installed on a wall, the hand-operated part shall be installed at a height of 80 cm or more and 1.5 meters or less from the floor surface and be easily visible. To show its usage in the method.

Conventionally, it is well known that an opening/closing device for a high smoke exhaust window has a structure in which an opening mechanism and a rolling-up mechanism are integrated, and its mounting position also complies with the above-mentioned laws and regulations.

Generally, when operating this type of opening/closing device, it is necessary to operate it in an emergency, so it is a one-touch type using a push button, lever, or pull cord, and is operated by a person of average height in an upright position. As mentioned above, the height is 80 to 15 cm from the floor for easy operation.
It is specified that it should be provided at a height of 0CIrL.

It is also necessary that the opening mechanism section be provided in a location where the person operating it can easily handle it during normal activities.

In contrast, there is no urgency to operate the winding mechanism.

It is best to operate after the emergency situation has subsided, giving you plenty of time.

In addition, the opening mechanism requires only one touch to operate, but the winding mechanism requires the bundle to be rotated many times to close the window, and the operating force is only about the same as the touch of a finger when opening the window. I can't afford it.

Since the bundle is opened and closed using a single wire, the more windows there are, the more times the bundle will rotate.

Furthermore, as the size of the window increases, the rotational force also increases.

Furthermore, the installation height of the winding mechanism section is 80 to 150 cm, unlike the opening mechanism section, making it difficult to operate.

As a result of various experiments, it was found that it is desirable for the installation height of the hoisting mechanism to be 60 to 90 cIrL from the floor surface.

Further, the installation location of the winding mechanism does not necessarily have to be at a location where the person operating it can easily handle it during normal activities.

There will also be a need to install it in a location that does not impair the aesthetics of the room, or in a location that does not cause any hindrance, taking into account constraints such as the configuration of the room and the installation of furniture.

The present invention divides the opening/closing control device for the high smoke exhaust window into two parts: a bundle box for hoisting the operating wire and an emergency manual release device, which satisfies the above regulations, and has a simple structure and reliable operation. The purpose is to provide.

That is, the present invention provides an opening/closing control device for a high smoke exhaust window of a type in which the upper end of the window rotates and opens with the lower end of the window as the center of rotation.
■The window and the window frame that houses the window have a space at the upper end that is made up of the upper end surface of the window, the window protrusion, the lower surface of the upper end of the window frame, and the side surface of the window frame when the window is closed. A wire guide member is fixed to the window side (1) horizontally on the upper end surface of the window pulley and the window edge adjacent to the pulley; A window frame side pulley is attached adjacent to the pulley and is movable from the horizontal direction to at least a slightly downward angle. Both pulleys are operated from a remote position and guided by the guide member when opening and closing the window. The window pulley, the window frame pulley wire guide member, and the window opening/closing operation wire are hidden in the space when the window is closed, and are normally connected to the high smoke exhaust window. A bundle box for winding and maintaining the operating wire that pulls the wire in the closing direction on a winding drum is hidden and disposed at a lower position in the room, and a ratchet integrated with the winding drum inside the bundle box is installed. Another wire is provided for pulling out the pawl that engages with the teeth, and this pulling wire is connected to a manual opening device installed at a position higher than the bundle box and easy to operate, and the smoke exhaust high window is opened by operating the manual opening device. This invention provides an opening/closing control device for a high smoke exhaust window, which is characterized in that it can be opened in an emergency.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to preferred embodiments illustrated in the accompanying drawings.

1 and 2 illustrate an example of a building opening provided with a plurality of high windows 1 (four windows in the figure).

These high windows 1 are of a type in which the upper end tilts inward (to the right in Figure 2) to open with the lower end as the center of rotation, and the tilting bias is performed, for example, by a spring housed in the stay 9. shall be taken as a thing.

Its closing movement and holding in the closed position are carried out by pulling the operating wire 3 that is passed over a pulley (described later) and keeping the tension with a ratchet. It extends into the provided bundle box 4.

The winding drum with ratchet inside this bundle box 4 (
The four windows are closed by winding the wire 3 (not shown).

In addition, by pushing down the emergency lever provided at the hand position of the vertical stile 6, that is, the lever of the manual release device 5, the ratchet teeth Lm in the bundle box 4 are disengaged from the pawl that engages with the teeth of the ratchet, and the winding drum is removed. By freely rotating the wire 3, the high window 1 is tilted inward and opened in an emergency manner.

As shown in the plan view of FIG. 5, the operating wire 3 rising from the vertical stile 6 inside the pipe 15 connects to the window frame side pulley 7 attached to the lower surface of the upper end of the window frame 2 on the left side of the drawing. It extends over a window-side pulley 8 attached to the upper end surface of the window 1 at a position adjacent to the window 1, and further extends to the next window via a pair of similar pulleys arranged on the right side of the drawing.

As shown in FIGS. 3 and 4, the window frame side pulley is attached to the lower surface 1'2 of the upper end of the window frame by a mounting base 10 via a horizontal pivot 11 so as to be tiltable at least up to a slight angle as shown in FIG. It is.

On the other hand, the window pulley 8 has its axis fixed perpendicularly to the upper end surface 13 of the window.

Further, a guide member 14 having a gently protruding surface is fixed to the outer edge 13' of the upper end surface of the window 1.

This guide member 14 has the effect of slidingly contacting the wire stretched between the pulley 7 and the pulley 8 and smoothing the movement of the wire.
It is preferable to use a material with excellent smoothness, abrasion resistance, and corrosion resistance, such as a thermoplastic synthetic resin such as polyethylene resin or a thermosetting synthetic resin such as phenol resin.

When the high window is closed, as shown in FIG. 2
The window 1 is completely hidden from the interior and exterior by the exterior side surface 16 of the window 1 and the interior side protrusion 17 of the window 1.

In the open position shown in FIG. 4, the pulley 7 is pulled by the wire 3 and rotates by a slight angle about the pivot @1111.

Although the window pulley 8 is of a fixed type, the wire 3 is guided by the guide member 14, so there is no problem with the operation of the pulley 8.

The initial force for tilting the high window when the wire 3 is loosened is due to the elastic force of the coil spring provided in the stay 9 (FIG. 3).

Details of the bundle box 4 are shown in FIGS. 6 to 8.

As shown in these figures, the operating wire 3 from the high window is attached to the Boo! hinge inside the bundle box 4. J
The winding drum 20I is wound up via winding drums 18 and 19.

The teeth of a ratchet 21, which is integral with the winding drum 20, are rotatable only in the wire winding direction by engagement with pawls 23 which are biased against the teeth of the ratchet by a spring 22.

The shaft 24 of the winding drum 20 has a spline so that it can engage with a spline on a bundle shaft coaxially spaced apart from the shaft 24.

The bundle 26 is disposed so as to protrude above the upper surface of the base bag 2γ of the building, and is normally biased upwardly by a spring 28 so as to be at a separate position.

The knob 29 on the top of the bundle shaft 25 is pushed in against the force l of the spring 28, and the splines of the bundle shaft 25 and the drum shaft 24 are engaged with each other, and in this state, the bundle 26
When the drum 20 is rotated, the drum 20 rotates and the wire 3 can be wound around the drum 20.

When the knob 29 is released, the spline is released and the drum 20 is held in that position by the action of the ratchet.

As best shown in FIG.
The pawl 23 that meshes with the ratchet 2 is attached so that it can rotate around the pivot 30, and the spring 22 engages the ratchet 2.
A pin 32 is attached to the other end of this claw 23, and a wire 31 is attached to this pin 32.
is connected.

This wire extends to a manual release device 5.

As the structure of the manual release device 5 is shown in detail in FIGS. 9a and 9b, an arrow-shaped lever 33 is fitted into a projection 35 of a sliding member 34.

This sliding member 34 is guided by a guide member 36 and can slide vertically.

The aforementioned wire 31 is connected to the pin 37 at the upper end of the sliding member 34.

This manual release device can be attached to a stile, column or wall of a building at 8
It can be installed at an easy-to-operate position from 0 cm to 1.5 meters.

If the arrow-shaped lever 33 of this manual release device is pushed down, that is, in the direction indicated by the arrow, the internal sliding member 3
4 moves downward and pulls the wire 31.

This movement of the wire inside the stile is such that it pulls the end of the wire 31 in the bundle box, so that the pawl 23 disengages from the teeth of the ratchet 21, the drum 20 is in a free rotation state, and the wire is pulled by the force pulled from the high window side. 3 can be freely extended to open the high window.

When the upper end of the pawl 23 is pulled to the left in FIG.
Even if the action of pulling 1 is stopped, it remains in this transition position, that is, the claw non-engagement position.

To return from this non-engaged position to the engaged position shown in FIG. 8, it is sufficient to pull up the lever 33 of the manual release device, extend the cable 31, and push back the claw 23.

Since the distance required to remove the pawl 23 from the ratchet 21, that is, the length of movement of the wire 31, is relatively short, the distance that the operating member 33 of the manual release device must be moved is also short, and the emergency release can be performed in a single action. This can be done with extremely easy operation.

As described above, according to the present invention, the bundle box for operating the high window for smoke exhaust is provided at the lower position, and the manual opening device for this is separately provided at a position 80 to 150 cm above the floor that can be easily operated in an emergency. Therefore, it is possible to satisfy the requirements of laws and regulations, and to have a simple structure and reliable operation.

Although the present invention has been described in detail above with reference to the preferred embodiment illustrated in the accompanying drawings, the present invention is not limited to this specific embodiment, and many changes and modifications may be made without departing from the spirit of the invention. Of course it can be done.
