Abstract

PROBLEM TO BE SOLVED: To reduce injuries and death by pressure by supporting a base on a floor surface by a column and a beam and lowering the base to the inside of a frame by a base lowering mechanism. SOLUTION: When an earthquake sensing mechanism 4a senses a quake set beforehand, a lock mechanism 3b is moved to the outer part of an earthquake-proof frame, the lick of the lowering of a bed 1 is release and the bed 1 is lowered from the state of being supported on the floor surface to the inside of the frame of a refuge room 2. As a result, the bed 1 is promptly, surely and stably lowered to the inside of the frame of the refuge room 2 and falls down on a first air bag device 7 by the guidance of a guide roller 6 pivoted along the column 2a. Thus, even when furniture arranged near the bed 1 falls down to the bed 1 by the occurrence of an earthquake, the bed 1 is lowered to the inside of the earthquake-proof frame inside the refuge room 2 and falling directly on the bed 1 is prevented by the column 2a and the beam 2b for constituting the earthquake-proof frame. Then, the possibility of getting a person sleeping on bedding injured or crushed to death is reduced.

Description

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 that protects human life in the event of an earthquake during bedtime.

[0002]

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

[0003]

By the way, when a person is awake and awake, a normal person can immediately run and escape to a shelter or the like as the 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 it is often impossible to evacuate a bedridden elderly person or a sick person even if he or she is awake.

Depending on the extent of the earthquake, a part or the whole of the building may collapse, and in this case, since the person is lying on the bedding, especially during sleep, the existence rate of the human body in the horizontal direction increases. , The possibility of injury or crushing due to falling objects from above is extremely high.

The present invention has been made in view of the above problems, and it is a descending type that can reduce the possibility of injury or crush death even when an earthquake occurs, especially even when the person is asleep. The main purpose is to get an evacuation bed.

[0006]

SUMMARY OF THE INVENTION According to the present invention, the above-mentioned problems constitute a bed on which bedding is placed, an evacuation room provided under the floor of a building, and an earthquake-resistant framework for the evacuation room. With a plurality of pillars and beams to support the platform on the floor surface in the flat state,
This is solved by a descending evacuation bed equipped with a platform lowering mechanism for lowering the platform into the framework of the evacuation chamber when an earthquake occurs.

In the descending evacuation bed according to the present invention, when an earthquake occurs, the bed supporting table is lowered by the table lowering mechanism into the seismic resistant framework of the evacuation room provided under the floor of the building, so that the earthquake occurs. Falling objects due to the above are blocked by the pillars and beams on the frame, and the possibility of falling to the table is reduced.For example, a person sleeping on the bedding may be injured or crushed by death. It becomes possible to reduce.
The pillars and beams may project to some extent on the floor surface.

In the evacuation bed according to the present invention,
The table lowering mechanism includes an earthquake detection device and a lock device that unlocks the table and allows the table to descend when the earthquake detection device detects an earthquake sway exceeding a preset strength. In this case, the table is automatically lowered into the earthquake-resistant framework of the evacuation room when, for example, an earthquake that exceeds a preset intensity occurs while sleeping.

In the descending evacuation bed according to the present invention,
The table lowering mechanism may include a lock device for locking the lowering of the table and an operating mechanism for unlocking the lock device by a manual operation. In this case, for example, when the earthquake detection device does not operate. Even if the user feels an earthquake and wakes up at bedtime, he / she can operate the operation mechanism to lower the platform into the earthquake-resistant framework of the evacuation room.

In the descending evacuation bed according to the present invention,
The table lowering mechanism can also include a jack device for returning the lowered table to a position on the floor surface.
For example, when performing regular operation inspections, when an earthquake subsides, or when the operation mechanism is operated by mistake,
It is possible to return the platform lowered into the earthquake-resistant frame of the evacuation room to the original position on the floor again.

The descending evacuation bed according to the present invention may be provided with a guide roll device for guiding the lowering of the table by the columns constituting the seismic resistant frame, which allows the table to be quickly and reliably lowered into the frame. It will be 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 chamber for cushioning the impact when the table is lowered and landed, and the table is lowered into the frame of the evacuation chamber. In this case, 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. As such a shock absorber, an air bag device can be specifically used, but other mechanical springs or fluid shock absorbers can also be used.

In the descending evacuation bed according to the present invention,
The upper part of the evacuation room may be provided with a cover device that shields the upper opening of the evacuation room when the platform is lowered. In this case, from the upper opening of the evacuation room after the platform is descended, the pillar of the earthquake-resistant frame is installed. It is possible to prevent falling objects that have not been blocked by the beams or beams, such as block-like relatively small-sized falling objects, from entering the framework of the evacuation chamber and falling on the table. The risk of injury or death from death can be further reduced.

As such a cover device, specifically, a protective shutter or an airbag device is used.
Of these, the protective shutter can be, for example, a steel (steel) slide shutter, and when the table is supported on the floor, it is rolled or folded and stored. When the platform is lowered, it is automatically or manually pulled out to block the upper opening of the evacuation room. Particularly in the case of automatic shielding, the sliding movement of the shutter can be interlocked by utilizing a part of the descending movement of the table.

On the other hand, the air bag device may be any device as long as it rapidly expands when the platform descends and covers the upper opening of the evacuation chamber. As an air source for expansion, a combination of a compressed air cylinder and an automatic or manual on-off valve is used. Of course, if a cushioning airbag is installed at the bottom of the evacuation chamber, the exhaust can be used. That is, the airbag device on the upper part of the evacuation room is inflated by the air exhausted when the cushioning airbag on the bottom part of the evacuation room is contracted to shield the upper opening of the evacuation room. Eliminates the need to deploy compressed air cylinders that require general maintenance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view showing a schematic structure of a descending evacuation bed according to an example of an embodiment of the present invention, in which (a) shows a steady state and (b) shows a state after operation. It shows the state. As shown in FIGS. 1 (a) and 1 (b), this evacuation-type evacuation bed has a bed (bed) 1 including a mattress 1a and a pedestal 1b, an evacuation room 2, and an earthquake that constitutes a table lowering device. Detection mechanism (earthquake detection device) 3a, lock mechanism (lock device) 3b, manual operation mechanism (operation mechanism) 3c
, A jack roll device 5, a guide roll device 6, a first airbag device 7, a protective shutter 8 and a second airbag device 9.

The bed 1 is a place on which bedding is placed and where the human 1c mainly rests and sleeps. Evacuation room 2
Four pillars 2 which are provided under the floor of the building and consist of earthquake-resistant members
It is formed by framing a and eight beams 2b.

The earthquake detection mechanism 3a is adapted to move the lock mechanism 3b outward of the seismic frame when an earthquake exceeding a preset strength is detected. The manual operation mechanism 3c has a push button switch structure which is attached to the rear portion of the bed 1. When the manual operation mechanism 3c is pressed, the lock mechanism 3b is moved to the outside of the seismic resistant frame like the earthquake detection mechanism 3a. It is designed to move toward. In a steady state, the lock mechanism 3b projects to the inside of the seismic frame to support the bottom of the bed 1 to lock the bed 1 from falling, and when the earthquake detection mechanism 3a operates or the manual operation mechanism 3c is operated. In this case, it moves toward the outside of the seismic frame to unlock the bed 1 and allow the bed 1 to descend.

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

The guide roll device 6 is attached to the side surface of the pedestal 1b and is interposed between the bed 1 and the column 2a constituting the seismic resistant frame. Then, when the earthquake construction machine mechanism 3a operates or when the manual operation mechanism is operated, the pillar 2a
Even if the bed 1 is quickly and reliably and stably lowered into the framework of the evacuation chamber 2 or the bed 1 is returned by the operation of the jack device 5, the bed 1 can be quickly and reliably and stably fixed to the original floor surface. It is designed to guide you to the upper position.

The first airbag device 7 is installed in the bottom of the frame of the evacuation chamber 2, and is inflated by previously holding the air infused from the cylinder (not shown) via the hose 7a inside. Therefore, the impact when the bed 1 is lowered into the framework of the evacuation chamber 2 can be softened. Although FIG. 2 is a schematic configuration diagram showing the interior of the evacuation chamber 2 of the descending evacuation bed, the bed 1 is removed in FIG.

The protective shutter 8 is installed in the upper part of the frame of the evacuation chamber 2 in the longitudinal direction, and is wound and stored in a spiral shape in the state shown in FIG.
When the vehicle is lowered into the framework of the evacuation room 2, as shown in FIG. 1B, it slides automatically or manually in the width direction within the framework of the evacuation room 2.

Like the protective shutter 8, the second airbag device 9 is installed in the upper part of the frame of the evacuation chamber 2 in the longitudinal direction, and is stored in a folded state in the state shown in FIG. 1 (a). When the bed 1 descends into the framework of the evacuation chamber 2, as shown in FIG. 1 (b), air is automatically injected from a cylinder (not shown) via the hose 9a, so that the evacuation chamber 2 can have a widthwise direction. It is designed to expand toward you.

In the evacuation bed of the descending type constructed as described above, when the earthquake detection mechanism 3a detects an earthquake (sway) exceeding a preset strength, the lock mechanism 3b is used.
Moves toward the outside of the earthquake-resistant frame, the downward lock of the bed 1 is unlocked, and the bed 1 is supported on the floor surface shown in FIG. 1 (a) to the state shown in FIG. 1 (b). It is lowered into the framework of the evacuation chamber 2 shown.

As a result, the bed 1 is promptly and reliably and stably lowered into the framework of the evacuation chamber 2 by the guide of the guide roll device 6 which rotates along the pillar 2a, and is placed on the first airbag device 7. To fall.

Therefore, due to the occurrence of the earthquake, furniture such as a closet and a bookshelf which were arranged in the vicinity of the bed 1 are replaced by the bed 1.
Even when the bed 1 falls toward the bottom, the bed 1 is lowered in the seismic resistant frame in the evacuation chamber 2, and the pillar 2a that constitutes the seismic resistant frame is formed.
And the beams 2b prevent the bed from directly falling on the bed 1 on which the bedding is placed, and even when an earthquake occurs at midnight or at dawn, for example, a person sleeping on the bedding is injured or crushed to death. It is possible to reduce the possibility that

The bed 1 also includes a first airbag device 7
Since the bed 1 is dropped upward, the shock generated when the bed 1 is lowered and landed is absorbed by the first airbag device 7, and the shock given to the person 1c on the bed 1 can be mitigated.

Further, when the bed 1 is lowered into the framework of the evacuation chamber 2, the protective shutter 8 and the second airbag device 9 are provided.
However, since it automatically slides or expands in the width direction of the evacuation chamber 2 and shields the upper opening of the evacuation chamber 2, falling objects that are not blocked by the pillars 2a and the beams 2b, such as light bulbs and ceilings, collapse. It is possible to prevent a fallen object such as a small piece from entering the framework of the evacuation chamber 2 in the case of an accident, and further reduce the possibility of injury or crush death.

Of course, when the occurrence of an earthquake is detected by itself, the manual operation mechanism 3c can be operated by itself to lower the bed 1 into the framework of the evacuation chamber 2 to prevent injury or crush death. .

When the bed 1 is lowered, the first airbag device 7 contracts due to the load of the bed 1. Therefore, air is injected into the first airbag device 7 in advance, and 1 Hose 7a connected to the 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. It is also possible to send the generated air into the second airbag device 9 and inflate the second airbag device 9 with the sent air.

This is because even if the seismic sensing mechanism provided in the bed lowering device 3 has an earthquake that exceeds a preset intensity, 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 chamber 2 can be shielded, and the bed It is possible to reduce the possibility that the person above 1 will be injured or deadly killed.

When the generated earthquake has subsided or when periodical operation inspections have been carried out, the manual operation mechanism 3
It is also possible to operate the jack device 5 by operating c to return the bed 1 lowered to the bottom of the evacuation chamber 2 in the framework to the original floor surface again. When the bed 1 is returned to the original floor surface again, the support portion 5b of the jack device 5 is
For example, a limit switch automatically lowers to the bottom of the evacuation chamber 2.

The protective shutter 8 is also returned to its original position on the floor by the jack device 5 when an earthquake that has occurred has subsided, or when periodical operation inspections have been carried out. Alternatively, it may be automatically wound into a spiral and stored. Of course, it may be stored manually.

Further, the second airbag device 9 is also attached to the bed 1
When the jack device 5 returns to the original position on the floor surface, the air injected into the second airbag device 9 may be automatically exhausted, or manually exhausted. You may
