Abstract

<P>PROBLEM TO BE SOLVED: To provide a bed capable of reducing the risk of being injured or crushed to death by automatically providing a person asleep or even awake thereon with an emergency shelter space when an earthquake has occurred. <P>SOLUTION: A bed bottom 1, which can be slanted downward being hinged on one side, is supported by the fulcrum of the hinge side and a support rod 4 which is attached via a hinge 7 at right angles to a side board 2 covering the other side. The side board 2 and the bed leg on that side are fixed by a pin 3 so that the support rod 4 can firmly prop up the bed bottom 1. In case of earthquake, a vibration sensor 5 installed on the bed detects its shake, when the pin 3 fixing the support rod 4 is pulled out to get the bed bottom 1 slanted, and then the person on the bed bottom 1 is forced to slide thereon. When the bed bottom 1 is slanted, it pushed down the support rod 4 as well, which pushes up the side bottom that used to be attached at right angles to the bed leg to become a top shelter board. As a temporary shelter space is created under the shelter board, the person getting into the space instantly is likely to be protected from the earthquake. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a technology for automatically securing an emergency evacuation space when an earthquake occurs, particularly when an earthquake occurs during sleep.

  In the past, various ideas have been devised to protect the house from injuries and crushing due to the collapse of furniture and buildings in the event of a major earthquake.

  There are various ways to prevent furniture from collapsing, such as tying a wall with furniture, or putting objects between the lower surface of the furniture and the floor, but these methods are effective when the earthquake shake is small. However, in the event of a tremor that exceeds the allowable limit, such as a huge earthquake, furniture injury and crushing are still inevitable.

  As countermeasures against the collapse of houses, there are many thoughts such as strengthening the earthquake-resistant structure by reinforcement and the aggravation effect by shaking the house, but in the event of a huge earthquake such as the Great Hanshin Earthquake or Chuetsu Earthquake, the limit that can be tolerated It seems that the collapse of the house is inevitable.

  Therefore, if it is unavoidable to collapse houses and furniture, there will be a problem of what to do with the evacuation space at the time of collapse. For example, there is a strong evacuation area, and there is a way to escape.

  These thoughts are based on the idea that people can move away, and in the case of a huge earthquake, they are not able to stand or move, especially when they go to bed. There is a strong feeling inside.

  The idea of turning the bed into an evacuation space comes here, for example, the idea that it surrounds the bed itself and becomes a protective shelter, the idea that the roof protrudes above the bed when an earthquake occurs and forms a protective space, etc. However, this idea becomes large-scale, and it is not easy to install in a small house, and the cost is high, so it is difficult to provide general expenses.

  Next, we arrive at the idea of using the bottom of the bed. For example, a lock pin is attached to the bottom plate, and the idea that the bottom plate falls to the lower part of the bed when the pin is released (see, for example, Patent Document 1 and Patent Document 2).

  This method is very large and is not cheap because it is connected to a brake motor via a crank lever or a support lot to hold or set the bed bottom plate, or a jack is used. And since the bed bottom plate falls over and falls down, another mechanism is required to protect the upper surface.

  As described above, even with the idea of using the lower part of the bed in the conventional method, it is large-scale, complicated, and inexpensive.

  The present invention is intended to solve such problems of the conventional configuration, and can be moved immediately under the bed at the same time as the occurrence of the earthquake, and at the same time can protect the upper surface. It aims at providing the device which has.

  When a sudden shaking such as an earthquake occurs, the bed bottom plate 1 supported by the hinge 6 on one side and the support rod 4 pulls out the pin 3 that fixes the support rod, so that the support rod 4 supports the bed bottom plate 1. It becomes impossible, and it opens to the lower side instantly by using the hinge 6 as a fulcrum, and the person on the bed is moved under the bed by using the inclined bottom plate 1 as a slope.

  This support bar 4 is attached at right angles via a side plate 2 and a hinge 7 covering one side of the lower part of the bed.

  When the side plate 2 and the bed foot are connected by the pin 3, the support bar 4 is fixed as a result, and the bed bottom plate 1 can be supported.

  This pin 3 is interlocked with the vibration sensor 5 and forcibly pulls out the connection between the side plate 2 and the bed foot when the sensor 5 is activated.

  When the pin 3 is disconnected, the bed bottom plate 1 is opened by the weight of the person and the bottom plate 1 with the hinge 6 supporting the bottom plate 1 as a fulcrum, and the support bar 4 is lowered by this pushing force. Pushed down to the side.

  When the support bar 4 is pushed down, the side plate 2 attached at a right angle is pushed up with the hinge 7 as a fulcrum, and the side plate 2 serves as an upper surface protection plate for the person who has slid down from the bed. Form.

  As described above, according to the present invention, when an earthquake occurs, a person on the bed can open the bed bottom plate 1 downward as a fulcrum to create a slide state and evacuate while sliding alone to the bottom of the bed.

  At the same time, the bed side plate 2 is pushed up, and the above-described person enters the bed side plate 2 to complete the temporary evacuation space protected by the side plate 2.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is a skeleton diagram showing the basic configuration of the present invention. FIGS. 2A and 2B are action diagrams when an earthquake occurs when a person is actually sleeping on a bed.

  FIG. 2 (b) shows that a person sleeping on the bed as shown in FIG. 2 (a) caused an earthquake and the apparatus was activated to move to the evacuation space below the bed.

  FIG. 3 is a perspective view of the seismic evacuation bed according to the present invention before the bed bottom plate is opened.

  The vibration sensor 5 attached to the lower part of the bed detects the shake.

  The motor 8 is driven by the detection of the vibration sensor 5 and the coupled pulley 9 is rotated.

  The rope connected to the pulley 9 is wound up, and the pin 3 connected to the opposite side of the rope is pulled out.

  When the pin 3 is pulled out, the connection with the side plate 2 is lost, and the support bar 4 attached at a right angle cannot support the bed bottom plate 1.

  The bed bottom plate 1 opens downward with the hinge 6 as a fulcrum under its own weight and the weight of a person.

  At this time, the proximity switch 10 attached to the bed bottom plate 1 and the bed main body frame and the iron piece 11 are separated from each other, and the contact point interlocked with the motor 8 is separated to stop the rotation of the motor 8.

  When the support bar 4 is pushed downward by the bed bottom plate 1, the side plate 2 attached at a right angle is pushed upward with the hinge 7 as a fulcrum.

  At this time, the support bar 4 that has been pushed down is set to a length that falls into the front end face of the bed bottom plate 1 and does not return to its original position.

  A person sleeping on the bed bottom plate 1 uses the inclined bed bottom plate 1 as a slope and slides or rolls into the space between the floor and the raised side plate 2.

  Here, the material of the bed bottom plate is described. To make it easier to slide, the bottom surface is better (for example, tatami mats), and if it is light, the bottom surface should be soft (for example, mattress). It will be.

  The material of the bed body may be wood, iron or plastic resin.

  Although it is conceivable that the motor cannot be operated due to a power failure due to a strong earthquake, since the present invention can be operated only for a few seconds after the pin comes off, the device operates faster than the wire disconnection time due to shaking.

  FIG. 4 shows another method of removing the pin 3.

  FIG. 4A is a side view and a front view in which the bed foot and the side plate 2 are connected by a compression spring 13 and connected by a pin 3, and a lock pin 12 is inserted to prevent the spring from being pulled out. It is.

  FIG. 4B is a side view and a front view of the state where the pin 3 is pulled out by the spring force when the lock pin 12 is pulled out, the bed leg portion and the side plate 2 are disconnected, and the side plate 2 is lifted. is there.

  FIG. 5 shows a method in which the connection between the bed foot and the side plate 2 by the pin 3 is stopped, and the side plate 2 is prevented from being lifted by the stop plate 14 supported by the hinge 15.

  FIG. 5 (a) is a state diagram in which the side plate 2 is fastened by the stop plate 14 to prevent the slid-up, and FIG. FIG.

  The present invention is a device for an earthquake caused by a person's earthquake, but it is not limited to a person, and if something that is crushed or damaged by an earthquake is placed on this device, it will not be damaged by collapse or the like. As a protection device, it can be sufficiently diverted.
