Description

[Detailed description of the invention] The present invention relates to a continuous ventilator having a vertical damper installed along the ridge of the roof of a building, and particularly relates to a continuous ventilator in which the vertical damper is opened and closed by an electric opening/closing device. .

A continuous ventilator with a conventional vertical damper has a first
As shown in the figure, a vertical damper 4 was opened and closed via a rope 2 and a pulley 3 by operating a manual winding device 1 installed on an indoor wall.

However, in this case, manual operation requires effort, and
This system had the disadvantage that it could not be used in time for immediate ventilation and smoke removal in case of an emergency.

Furthermore, since the vertical damper 4 also serves as the outer panel of the continuous ventilator, there are drawbacks such as wind and rain blowing into the building when the damper 4 is opened.

The present invention has been made to eliminate the above-mentioned drawbacks, and aims to provide a continuous ventilator that can quickly and reliably open and close the damper without requiring any effort and that can prevent wind and rain from blowing in. purpose.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a continuous ventilator equipped with an electric damper opening/closing device according to the present invention will be described in detail with reference to the drawings.

In FIG. 2, two draining plates 7 are installed facing each other on both longitudinal edges of a ventilation opening 6 (see FIG. 3) that opens with a certain width along the ridge of the roof of a building 5. has been done.

As shown in FIG. 3, aggregates 8 are erected on the inner surface of the draining plate 7 by bolts, nuts, welding, etc., with the lower part of the aggregate 8 in contact with the inner surface.

As shown in FIG. 4, the aggregates 8 are formed of, for example, an angle material, and are arranged at regular intervals along the longitudinal direction of the draining plate 7, and are provided in pairs facing each other on the inner surface thereof. There is.

A brace 9 made of angle material or the like is stretched substantially horizontally between the opposing aggregates 8, 8.

The braces 9 serve to maintain a constant spacing between the aggregates 8.8 and to reinforce them.

As shown in FIG. 3, a roof-shaped aggregate 10 is attached to the top of the aggregate 8, and a canopy board 11 is placed on its upper surface to cover the upper part of the ventilation opening 6.

The cap board 11 may be made of any material such as a metal plate or wood, but if a transparent or translucent glass plate or acrylic plate is used, sufficient light can be let into the building.

A vertical damper 12 is provided in the space between the kasa board 11 and the upper end edge of the drain board 7, which are separated by one interval between the aggregates 8, 8.

As shown in FIG. 3, this damper 12 is rotatably connected at its center to a damper shaft 13 stretched approximately horizontally between the aggregates 8, 8, and as shown in FIG. A plurality of ventilation openings 6 are successively provided along the longitudinal direction.

Therefore, the space above the ventilation opening 6 can be opened and closed by the damper 12.

One or more braces 9 of the plurality of braces 9 above
As shown in FIG. 3, an electric motor 14 is attached to the lower surface of the motor.

This electric motor 14 is a power source for opening and closing the damper 12, but its mounting position is not limited to the above-mentioned position, and the electric motor 14 is capable of transmitting rotation to a driving shaft 16 of a reduction gear 15, which will be described later. It may be installed in any position as long as it is.

As shown in FIG.
is installed.

This speed reduction device 15 reduces the rotational speed of the electric motor 14 using a reduction gear or the like and supplies the rotational force to a damper operating shaft 20, which will be described later. As shown in FIG. A chain gear 17 is fixed to the driving shaft 16, and is connected to a chain gear fixed to the rotating shaft of the electric motor 14 by a roller chain.

The speed reduction device 15 is provided with two driven shafts 18, each having a chain gear 19 fixed thereto.

This chain gear 19 is for rotating a damper operating shaft 20, which will be described later.

The speed reduction device 15 and the continuously provided damper 12
As shown in FIG. 4, a damper operating shaft 20 is stretched parallel to the damper 12 between the damper 12 and the damper 12. As shown in FIG.

As shown in FIG. 3, this damper operating shaft 20
A bearing member 21 protruding from the center toward the reduction gear 15
As shown in FIG. 4, a chain gear 22 is fixed approximately at the center thereof.

This chain gear 22 and the chain gear 19 of the reduction gear 15 are connected by a roller chain 23, and the electric motor 1
4 and the reduction gear 15, the damper operating shaft 20
rotates.

Rotating rods 24 are attached to the damper operating shaft 20 at intervals of one for each damper 12 provided continuously.

The tip of the rotating rod 24 and the outer end of the damper 12 are connected to the third
As shown in the figure, they are connected by an actuating arm 25.

Therefore, as the damper operating shaft 20 rotates, the successive dampers 12 are simultaneously rotated in the same direction, as shown by the chain line in FIG.

Note that the driven shafts 18° 18 of the speed reduction device 15 are each rotated in opposite directions with the same speed reduction, so the opposing dampers 12 are synchronously rotated to open and close in line symmetry. .

Further, the opening angle of the damper 12 (for example, about 60° C.) is determined by the damper operating shaft 20, the bearing member 21, the chain gear 22, or the rotating rod 24.
This is done by operating an angle control limit switch (not shown) provided on one of the above.

As shown in FIG. 2, an end plate 26 and an outer plate 27 are provided on the outer periphery of each of the structural members.

Therefore, unlike the conventional example shown in FIG. 1, the damper does not also serve as an outer plate, and wind and rain can be prevented from blowing into the damper.

Note that the reference numeral 28 indicates a partition plate provided at each interval of the aggregates 8 inside the outer panel 27.

In the above description, an example was shown in which the connection between the electric motor 14 and the speed reduction device 15 and the connection between the speed reduction device 15 and the damper operating shaft 20 are performed by a chain gear and a roller chain. The present invention is not limited to this, and may be a combination of a pulley and a belt.

To use the continuous ventilator according to the present invention, the operating switch 29 (such as a three-point switch) installed on the indoor wall (
By operating the electric motor 14 (see FIG. 3) to rotate the electric motor 14 in the forward or reverse direction, the dampers 12 that are successively provided opposite to each other can be opened or closed at the same time.

In addition, the length of the damper operating shaft 20 is desirably within 259 mm (total length within 5077 L) from the chain gear 22 fixed to the shaft toward both ends, taking into consideration torsion due to rotation.

As explained above, the present invention is used as a power source for opening and closing the vertical damper 12 that is continuously provided in the longitudinal direction of the ventilation opening 6 that opens with a constant width along the ridge of the roof of the building 5. Since the electric motor 14 is used to operate the damper 12 via the reduction gear 15 and the long damper operating shaft 20, the damper 12 can be operated extremely quickly and reliably by simply operating the operation switch 29 without requiring any effort. 12 can be opened and closed simultaneously.

Therefore, it is possible to deal with emergencies such as fires and small explosions.

In addition, since the outer side of the damper 12 is wrapped with the outer plate 27,
Even when the damper 12 is opened, it is possible to prevent rain and wind from blowing into the building from the space, and this has the effect of improving the livability inside the building.
