Description

[Detailed Description of the Invention] The present invention relates to an emergency evacuation door that is installed in each room for the emergency evacuation of residents or guests in the event of a fire in a building or hotel.

In recent years, so-called building fires have been occurring frequently in high-rise buildings, multi-tenant buildings, and mid-rise buildings with inadequate disaster prevention measures.
One of the biggest causes of death for people fleeing in search of safe evacuation sites or emergency exits is smoke containing carbon monoxide, as well as toxic gases from new building materials used for interior decoration. It is believed that people are instantly exposed to these volcanic smoke and gas and die.

Therefore, it is no longer possible to simply analyze that people died in the flames as seen in fires in traditional wooden buildings. The fact has been brought up that the safety of life cannot necessarily be guaranteed as long as one is present.

Therefore, the best method is to escape from the room to the outside in an instant, but the only evacuation equipment that has traditionally been provided on each floor or room of a building is life ropes and evacuation ladders. This raises the question of whether an untrained person can use these equipment to escape safely in a timely matter, and the storage of these evacuation equipment is also inadequate. If so, an inconvenient situation may occur in which the user cannot find the location and cannot use it when needed.

Taking the above points into consideration, escape devices that open and close by the operation of cylinders and escape devices that form bag-like escape routes have been seen, but they are not designed to prevent objects falling from overhead, such as building debris. Nothing was found.

Additionally, as is the case with evacuation devices in general, many of them suffer from electrostatic distortion when stored inside a building.

Therefore, as a result of various studies in view of the above circumstances, this invention opens an escape exit from the room to the outside space of the building using only remote control.
In an evacuation device that can set the lifeline provided at the escape exit to a usable state at the same time as opening the evacuation exit,
To provide an escape door device for emergency evacuation that protects overhead by an escape door during escape and does not become bulky indoors when stored.

An embodiment of the present invention will be described below based on the drawings.

First, as shown in Figures 1 and 2, reference numeral 1 designates an escape exit opened from the room A to the outside space B of the building, and is installed at a necessary place or in each room on each floor of a building, hotel, etc. (not shown). Each one is set up in such a way that a normal adult can pass through it without difficulty (for example, 80 cm).
square size).

A door 3 is attached to this escape port 1 so as to be able to swing up and down from the room A to the outside space B via hinges 2, 2, and a door 3 is installed at an appropriate position in the center of the door 3. A pneumatic cylinder 4 is approached from diagonally above the external space B, and a piston rod 5 provided on the pneumatic cylinder 4 is pivotally mounted.

The pneumatic cylinder 4 is a conventionally known device as disclosed in Japanese Utility Model Publication No. 48-7496, and the operation within the cylinder is a differential type. The entry and exit operations are performed from 4 onwards.

Therefore, 6 is a flexible tube that constantly supplies compressed air necessary for the differential operation of the pneumatic cylinder 4 to the cylinder 4, and is connected to a source air reservoir (not shown) provided at a suitable location.

Further, 7 fixes the pneumatic cylinder 4 and attaches it to the external wall surface of the building above the escape exit 1 in order to make the door 3 have an appropriate angle.
The mounting is a metal fitting, and the angle can be adjusted freely.

On the other hand, the piston rod 5 is pivoted at an appropriate position in the center of the door 3 on the side of the external space B, and this pivot portion 8 is shaped to sandwich the thickness of the door 3 as shown in FIG. A pair of locking plates 9, 9' are held together by bolts 10...10 that pass through the thickness of the door 3 and are screwed together. A life line 1 with an iron core is attached to the side locking plate 9'.
1 is attached via a speed governor 12 provided to eliminate (make it zero) the descending acceleration.

Therefore, the lifeline 11 is connected to the piston rod 5, the pneumatic cylinder 4, the mounting bracket 7, and the building's external wall surface C via the pivot portion 8 in the strongest and most robust route.

Here, the speed governor 12 is a conventionally known one consisting of a pulley, a gear, and a centrifugal brake as disclosed in Japanese Utility Model Publication No. 56-2981, and when the lifeline 11 moves, it is linked to the pulley shaft. When the gear rotates and its rotation speeds up, centrifugal play occurs; the knee works to reduce the acceleration to zero, allowing the robot to descend from a height at a constant speed regardless of the weight hanging from the lifeline 11. There is no shock.

In addition, the proximal end 11a of the lifeline 11 is provided with a belt 11c which is attached in an annular shape suitable for wrapping around the human body via a fastening fitting 11b, and can be adjusted as appropriate with a tightening ring 11d. There is.

On the other hand, the remaining portion 11e of the lifeline 11 is wound onto a reel 13 and placed near the escape port 1 in the room A.

Next, the control of the compressed air supplied to the pneumatic cylinder 4 in order to differentially operate the cylinder 4 is performed by switching a solenoid valve, which is conventionally known, for example, as disclosed in Japanese Utility Model Publication No. 53-22468. The solenoid valve is remotely operated by switching a switch (not shown) installed at a predetermined location, and even if a large number of the pneumatic cylinders 4 are installed, the differential can be controlled at once. It is set up as follows.

Note that this control method is a generally known method, and the switching of the above-mentioned switch not only controls the supply of compressed air to the pneumatic cylinder 4, but also controls the lighting of the emergency lights installed in the room A and the sounding of the emergency bell. It may be incorporated into the above control system as a device that causes the bell to operate, and may also have a circuit configuration so as to be interlocked with various fire detectors and the like.

In this embodiment constructed in this way, the pneumatic cylinder 4 is in a state showing the closing operation of the door 3 in FIG. The door 3 is pressed so that it does not open, and the door 3 is fixed by the stopper 14 so that it cannot enter the room A side any further.

In the event of an emergency, the switch can be changed and the fourth
As shown in the figure, the pneumatic cylinder 4 is differentially moved to insert the piston rod 5 into the cylinder, and the door 3 is opened toward the external space B as shown by the arrow.

Therefore, the door 3 protrudes to the side of the room B, and the lifeline 11 is also suspended in a ready-to-use state.

Moreover, the door 3 acts as a protective eaves and has the effect of preventing objects falling from above, and the person using the lifeline 11
A reel 13 that winds up the remaining portion 11e of the lifeline 11
If you drop it from exit 1 and unwind it before descending, you can safely descend while using this unwound lifeline as a guide.

Furthermore, since door 3 must be opened and closed by remote control, it cannot be opened from room A, and even if it is installed in a hotel or inn, it may be used maliciously by guests. There is no fear that an escape door will be opened and people will be forced to stay overnight for free.

In this invention, the piston rod of the pneumatic cylinder not only acts to open and close the door, but also connects a lifeline for escape via the pivot joint of the piston rod to the door. Therefore, the installation of the lifelines can be carried out safely and reliably against the load.
