DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a descent type evacuation head for protecting human lives when an earthquake occurs at bedtime.

[0002]

2. Description of the Related Art As a prior art related to the present invention, there is a shelter as a shelter in case of an earthquake.

[0003]

By the way, when a person is awake and awake, a healthy person can immediately run and escape to the shelter as an evacuation center even if an earthquake occurs. Although it is possible, it is difficult for a healthy person to immediately run and escape during bedtime, and in many cases, bedridden elderly and sick people cannot evacuate even if they are awake.

Depending on the degree of the earthquake, a part or the whole of a building may collapse. In this case, especially when sleeping, the human body in the horizontal direction increases because of lying on the bedding. Therefore, the possibility of injury or pressure death due to falling objects from above is extremely high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a descending type capable of reducing the possibility of injuries and injuries when an earthquake occurs, particularly when an earthquake occurs while sleeping. The main purpose is to obtain an evacuation bed.

[0006]

According to the present invention, there is provided a platform for placing bedding, an evacuation room provided under a floor of a building, and a seismic framework for the evacuation room. With a plurality of pillars and beams to support the table on the floor at normal times,
This problem is solved by a descending evacuation bed including a platform lowering mechanism that lowers the platform into the framework of the evacuation room when an earthquake occurs.

In the descending evacuation bed according to the present invention, when an earthquake occurs, the table supporting the bedding is lowered into the seismic framework of the evacuation room provided under the floor of the building by the table lowering mechanism. The fallen object due to is blocked by the pillars and upper beams constituting the framework, the possibility of falling to the table is reduced, for example, the possibility that a sleeping person on bedding may be injured or killed It becomes possible to reduce.
Incidentally, the columns and beams may protrude to some extent on the floor surface.

In the descending evacuation bed according to the present invention,
The platform lowering mechanism includes an earthquake sensing device, and a lock device that unlocks the platform and allows the platform to descend when the earthquake sensing device senses an earthquake shaking exceeding a preset intensity. In this case, for example, when an earthquake exceeding a preset intensity occurs while sleeping, the table is automatically lowered into the seismic framework of the evacuation room.

In the descending evacuation bed according to the present invention,
The platform lowering mechanism may include a locking device that locks the lowering of the platform and an operation mechanism that unlocks the locking device by manual operation.In this case, for example, when the earthquake sensing device does not operate. Even so, if the user wakes up while sleeping at the time of feeling an earthquake, he can operate the operating mechanism himself to lower the platform into the seismic framework of the evacuation room.

In the descending evacuation bed according to the present invention,
The platform lowering mechanism can also include a jack device for returning the platform in the lowered state to a position on the floor surface,
For example, when performing periodic operation inspections, when the earthquake subsides, or when you operate the operation mechanism by mistake,
The platform lowered into the seismic framework of the evacuation room can be returned to its original position on the floor.

[0011] The descending evacuation bed according to the present invention may include a guide roll device for guiding the lowering of the platform by the pillars constituting the seismic frame, whereby the platform is quickly and reliably lowered into the framework. It becomes possible.

The descending evacuation bed according to the present invention may be provided with a shock absorbing device on the bottom surface of the evacuation room to reduce the impact when the table descends and arrives on the floor, and the table is lowered into the framework of the evacuation room. When this occurs, the shock absorber serves as a cushion for the table, and it is possible to reduce the impact when the table is lowered and landed. Specifically, an airbag device can be used as such a shock absorber, but other mechanical springs or fluid shock absorbers can also be used.

In the descending evacuation bed according to the present invention,
A cover device may be provided above the evacuation room to cover the upper opening of the evacuation room when the table is lowered. It is possible to prevent falling objects not blocked by beams or beams, for example, massive small falling objects, from entering the framework of the evacuation room and falling onto the table, and the falling objects can prevent humans on the bedding. The possibility of injury or injuries can be further reduced.

As such a cover device, specifically, a protective shutter or an airbag device is used.
Among them, the protective shutter can be, for example, a slide shutter made of steel (steel), and when the base is supported on the floor surface, it is wound in a roll shape or folded and stored. When the platform is lowered, it is automatically or manually pulled out to cover the upper opening of the evacuation room. In particular, in the case of automatic shielding, the sliding movement of the shutter can be linked using a part of the descending movement of the table.

On the other hand, the airbag device only needs to be one that rapidly expands when the table descends and covers the upper opening of the evacuation chamber. As the air source for inflation, a combination of a compressed air cylinder and an automatic or manual opening / closing valve is used. Of course, when a buffer airbag is installed at the bottom of the evacuation room, the exhaust air can be used. That is, the airbag device at the top of the evacuation room is inflated with air exhausted when the cushioning airbag at the bottom of the evacuation room contracts, so that the upper opening of the evacuation room is shielded. There is no need to provide a compressed air cylinder or the like that requires regular maintenance.

Four pillars 2 installed below the floor of the building and made of seismic members
a and eight beams 2b.

The earthquake sensing mechanism 3a moves the lock mechanism 3b outward of the earthquake-resistant framework when an earthquake exceeding a preset intensity is sensed. The manual operation mechanism 3c is attached to the mirror portion of the bed 1 and has a push button switch structure. When the manual operation mechanism 3c is pressed, the lock mechanism 3b is moved to the outside of the seismic framework in the same manner as the earthquake detection mechanism 3a. It is designed to move toward. In a steady state, the lock mechanism 3b protrudes inside the seismic framework to support the bottom of the bed 1 and lock the lowering of the bed 1, and when the earthquake sensing mechanism 3a is activated or the manual operation mechanism 3c is operated. In this case, the bed 1 is moved outward and the bed 1 is unlocked to allow the bed 1 to descend.

The jack devices 5 are installed at the four corners of the bottom of the framework of the evacuation room 2, and when the bed 1 is lowered into the framework of the evacuation room 2, lift the bottom of the lowered bed 1;
The bed 1 can be returned to the original position on the floor surface again. The jack device 5 moves up and down by operating the manual operation mechanism 3c.

The guide roll device 6 is attached to the side surface of the gantry 1b, and is interposed between the bed 1 and the pillar 2a constituting the aseismic framework. Then, when the earthquake construction machine mechanism 3a operates or the manual operation mechanism is operated, the pillar 2a
The bed 1 is quickly and reliably lowered down into the framework of the evacuation room 2 along the path, or even when the bed 1 is returned by the operation of the jack device 5, the bed 1 is quickly and surely and stably placed on the original floor surface. It is designed to guide you to the upper position.

The first airbag device 7 is installed at the bottom of the framework of the evacuation room 2 and is inflated by previously holding air injected from a cylinder (not shown) via a hose 7a. In addition, the impact when the bed 1 is lowered into the framework of the evacuation room 2 can be reduced. FIG. 2 is a schematic configuration diagram showing the inside of the evacuation room 2 of the descending evacuation bed, but in FIG. 2, the bed 1 is removed.

The protective shutter 8 is installed in the upper part of the framework of the evacuation room 2 in the longitudinal direction, and is wound and stored in a spiral shape in the state shown in FIG.
As shown in FIG. 1 (b), when is moved down into the framework of the evacuation room 2, it slides automatically or manually in the width direction within the framework of the evacuation room 2.

The second airbag device 9 is installed in the upper part of the framework of the evacuation room 2 in the longitudinal direction, like the protective shutter 8, and is stored in a folded state in the state shown in FIG. When the bed 1 descends into the framework of the evacuation room 2, air is automatically injected from a cylinder (not shown) via a hose 9a as shown in FIG. It expands toward it.

In the descending evacuation bed configured as described above, when the earthquake detecting mechanism 3a detects an earthquake (shake) exceeding a preset strength, the locking mechanism 3b is used.
Moves outward from the aseismic framework, the lowering lock of the bed 1 is released, and the bed 1 is moved from the state of being supported on the floor shown in FIG. It is lowered into the framework of the evacuation room 2 shown.

As a result, the bed 1 is quickly, reliably and stably lowered into the framework of the evacuation room 2 by the guide roll device 6 rotating along the column 2a, and is placed on the first airbag device 7. Fall.

Accordingly, due to the occurrence of the earthquake, furniture such as a closet and a bookshelf arranged near the bed 1 may be moved to the bed 1.
Even if the bed 1 falls down, the bed 1 is lowered in the earthquake-resistant framework in the evacuation room 2 and the pillar 2a constituting the earthquake-resistant framework
The beam 2b prevents the bed 1 from directly falling on the bed 1 on which the bedding is placed. Even if an earthquake occurs at midnight or dawn, for example, a person sleeping on the bedding may be injured or killed. Or the likelihood of being reduced.

The bed 1 is provided with a first airbag device 7.
Since the bed 1 falls upward, the impact generated when the bed 1 descends and reaches the floor is absorbed by the first airbag device 7, and the impact given to the person 1c on the bed 1 can be reduced.

Further, when the bed 1 is lowered into the framework of the evacuation room 2, the protective shutter 8 and the second airbag device 9
However, the object automatically slides or expands in the width direction of the evacuation room 2 to block the upper opening of the evacuation room 2, so that a falling object not blocked by the pillar 2 a or the beam 2 b, for example, a light bulb or a ceiling collapses. In such a case, it is possible to prevent a falling object such as a small piece from entering the framework of the evacuation room 2, and further reduce the possibility of injuries or injuries.

Of course, when the occurrence of an earthquake is detected by itself, the user can operate the manual operation mechanism 3c to lower the bed 1 into the framework of the evacuation room 2 to prevent injuries and pressure death. .

When the bed 1 is lowered, the first airbag device 7 contracts due to the load of the bed 1, so that air is injected into the first airbag device 7 in advance, and Hose 7a connected to 1 airbag device 7
And the hose 9a connected to the second airbag device 9 are connected to each other, so that when the bed 1 is lowered into the framework of the evacuation chamber 2, the first airbag device 7 contracts to exhaust air. The supplied air may be sent into the second airbag device 9, and the second airbag device 9 may be inflated by the sent air.

The reason is that if an earthquake exceeding the intensity set in advance in the earthquake sensing mechanism provided in the bed lowering device 3 occurs, each electric system may be cut off. By connecting the hose 7a connected to the first airbag device 7 and the hose 9a connected to the second airbag device 9 to each other, the upper opening of the evacuation room 2 can be shielded, It is possible to reduce the possibility that the first person is injured or injured.

When the generated earthquake subsides or when a periodic operation check is performed, the manual operation mechanism 3
By operating c, the jack device 5 can be operated to return the bed 1 lowered to the bottom of the framework of the evacuation room 2 to the original floor again. When the bed 1 is returned to the original floor again, the support portion 5b of the jack device 5
For example, the limit switch automatically descends to the bottom of the evacuation room 2.

The protective shutter 8 is also returned to its original position on the floor by the jack device 5 when the generated earthquake has subsided or when a periodic operation test is performed. Alternatively, it may be automatically wound into a spiral shape and stored. Of course, it may be stored by manual operation.

Further, the second airbag device 9 also
Is returned to the original position on the floor by the jack device 5, the air injected into the second airbag device 9 may be automatically exhausted, or may be manually exhausted. It may be.
