DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing device between compartments, and more particularly to a door opening / closing device for a compartment which can ensure the flow of air from one compartment to another compartment.

[0002]

2. Description of the Related Art In recent years, in a building, a safety compartment space such as an annex or a corridor is supplied with air by a fan to keep the safety compartment space in a pressurized state and to flow in the safety compartment space in one direction. There is known a pressurized smoke exhaust system which secures an air flow route to prevent smoke from entering in the event of a fire and at the same time enables smoke exhaust.

Conventionally, in such a pressurized smoke exhaust system, an air flow route from one room to the other is secured between adjacent rooms forming a safety compartment space and an adjacent room such as a corridor. For this purpose, as shown in FIG. 4, an air passage 4 such as a rag is provided on a wall 3 that separates the adjacent annex 1 from the corridor 2.

In FIG. 4, reference numeral 5 denotes an annex room 1 and a corridor 2
It is a door that opens and closes the entrance 6 between the doors, and the door 5 may be provided with a rattle for securing an air flow route.

[0005]

However, in the conventional method as described above, since an air passage such as a rag is required to be provided in a wall portion or a door of the space, the degree of freedom in designing the wall or the door is limited. In addition to being damaged, when the air passage is formed in the wall, there is a problem that the arrangement of the furniture arranged in the room is restricted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and an object of the present invention is to use an opening / closing of a door provided at an entrance of a partitioned space such as an annex and a corridor to open air. An object of the present invention is to provide an entrance opening / closing device capable of securing a flow path.

[0007]

A compartment room opening / closing device according to the present invention is a fan for supplying air to one compartment.
To ensure airflow to the other adjacent compartment
In the door opening / closing device for compartments, upper and lower divided doors are provided at the entrance between adjacent compartments so that they can be opened and closed, and all doors are opened in the same direction in normal times.
When smoke reaches, the upper door closes, creating a hot air current or flame.
When the vehicle reaches the vicinity of the door, the lower door is closed .

[0008]

According to the present invention, in normal times, all doors are kept the same.
Open in one direction to form an air passage from one compartment to the other. As a result, there is no need to provide a separate air passage in the door or in the compartment wall. When smoke reaches near the door due to a fire, the upper door is closed.
To prevent smoke from entering the adjacent compartment. Further
When the hot air or flame reaches near the door,
Door to prevent flames from entering adjacent compartments
You.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a configuration of an entrance opening / closing device according to an embodiment of the present invention.

In FIG. 2, a partition 12 is defined between an annex room 10 and a corridor 11 constituting a safety compartment.
An entrance / exit 13 is formed in the partition wall 12 so that it can pass between the annex room 10 and the corridor 11.
An upper door 14 and a lower door 15 that are double-folded are provided so as to be openable and closable. As shown in FIG. 2, a projection 16 is formed on the upper edge of the lower door 15 so as to engage with the lower edge of the upper door 14. The door 14 is engaged with the protrusion 16 so that the lower door 15 is integrally opened toward the vestibule 10.

The upper door 14 and the lower door 15 are exhausted by a pressurized smoke exhaust system. The upper door 14 is provided when a smoke detector 17 provided on the ceiling of a fire occurrence location detects smoke. A known release mechanism (not shown) that operates is provided, and the lower door 15 is provided with a known release mechanism that operates when a heat detector 18 provided on a wall or the like of the corridor 11 detects a high temperature airflow or fire. (Not shown).

In FIG. 1, reference numeral 19 denotes an air supply port provided on the ceiling or the like of the annex room 10 for supplying pressurized air. The air supply port 19 is supplied through a duct (not shown). It is connected to a fan (not shown).

Next, the operation of the embodiment configured as described above will be described. As shown in FIG. 3A, the upper door 14 and the lower door 15 in a normal state are open to the lounge room 10 side.

In such a state, if a fire occurs,
Known pressurized flue gas systems are activated automatically or by means. When the pressurized smoke exhaust system is activated, an air supply fan (not shown) is activated to supply air from the air supply port 19 to the auxiliary room 10.
And the inside of the auxiliary room 10 is pressurized. At the air supplied to the Fushitsu 10 simultaneously opened doorway 13
Through to the corridor 11.

On the other hand, when the smoke generated by the fire reaches the vicinity of the door and this smoke is detected by the smoke detector 17, the release mechanism of the upper door 14 operates to release the open state of the upper door 14. Therefore, the upper door 14 closes as shown in FIG. This prevents smoke from entering the lounge 10.

Thereafter, when a high-temperature air current or a fire reaches the vicinity of the door due to the spread of the fire, the heat detector 18 senses this, and the release mechanism of the lower door 15 is operated to open the lower door 15. Cancel. For this reason, the lower door 1
5 closes as shown in FIG. Thereby, the annex room 10 is partitioned to form a safety compartment space, and the intrusion of hot air or fire into the space is prevented.

In this embodiment as described above, the lounge 1
The upper and lower doors 15 and 15 divide the entrance and exit from the corridor 11 into upper and lower doors. The upper door 14 is closed and the lower door 15 is opened when smoke is detected when a fire occurs. To prevent smoke intrusion into the auxiliary room 10 by pressurized air supply to the auxiliary room 10 and to enable smoke exhaust accompanying the flow of air. It is not necessary to provide a door, and it is possible to perform pressurized smoke exhaust using the door of the doorway.

Further, since it is not necessary to provide an air passage such as a rag in the door or the partition, the degree of freedom in designing the door and the wall is improved, security inspection is facilitated, and the arrangement of furniture is limited. Never.

In the above-described embodiment, the upper door 14 and the lower door 15 are opened by operating the release mechanism of the upper door 14 and the lower door 15 by detecting the smoke by the smoke detector 17. A fire may be detected by a thermal fuse, and the lower door 15 may be closed by operating the thermal fuse.

Further, in the above embodiment, the case where the present invention is applied to the pressurized smoke exhaust system has been described, but the present invention is not limited to this. For example, the present invention can be used for any section between sections that generate an air flow. The opening and closing of the upper door and the lower door may be manually performed.

[0021]

As described above, according to the present invention, an upper door and a lower door which are vertically divided are provided at the entrance between adjacent compartments so as to be openable and closable.
Open when the smoke reaches the door, close the upper door,
When warm air or flame reaches near the door, lower door
Since it is configured to be closed, the air flow route can be easily secured by opening and closing the door without providing an air passage of another structure. Accordingly, the degree of freedom in designing the doors and walls is improved, and there is an effect that the air passage does not limit the arrangement of furniture in the compartment.
