Description

  The present invention relates to a seismic protection device suitable for protecting at least one of a house and a person in the house when an earthquake arrives.

Conventionally, in order to protect a human body from an earthquake, for example, a personal protective equipment system described in Patent Document 1 has been proposed. In this system, an airbag is employed as a personal protective equipment, and a configuration is adopted in which a storage box storing the airbag is installed one by one along the wall of the ceiling of the building. And when the building starts to collapse due to the earthquake, the deformation detection means detects that the building has started to collapse, and along with this, the gas generating means generates high-pressure gas and injects it into each airbag, Each airbag is inflated by injecting high-pressure gas to protect the human body while delaying the collapse of the building.
Japanese Patent Laid-Open No. 08-332243

  However, according to the personal protective equipment system described above, since the inflation of each airbag is started after the building starts to collapse due to an earthquake, the timing of inflation of each airbag is not appropriate and is slow. Therefore, depending on the inflation of each airbag, personal protection is insufficient. Further, as described above, since the inflation of each airbag starts after the building starts to collapse due to an earthquake, the building cannot be protected.

  In view of the above, the present invention appropriately protects at least one of the house and the person in the house with an air bag before the original large shake of a large earthquake arrives at the house. An object of the present invention is to provide a seismic protection device.

In solving the above-mentioned problems, the seismic protection device according to the present invention, according to claim 1,
A gas discharge device (30) supported on a part of the ceiling (11) of the room in the house (10) or the upper part of the peripheral walls (12, 13) of the room, and supported in a folded state outside the gas discharge device A belt-shaped airbag (20) to be provided,
The gas release device
An inflator (35) that releases gas when driven;
Receiving means (32b, 33) for receiving the earthquake prediction data when the earthquake prediction data is transmitted by radio waves from the Japan Meteorological Agency;
A determination means (40, 41) for determining that a large earthquake is predicted based on an output representing the earthquake prediction data from the receiving means when the receiving means receives the earthquake prediction data;
Drive means (50) for driving the inflator based on the judgment of the arrival of the earthquake by this judgment means is built-in,
The airbag is deployed so that the gas discharged from the inflator is flowed into the inside of the living room so as to be annular toward the inner surface.

  According to this, when the earthquake prediction data is transmitted by radio waves from the Japan Meteorological Agency, the receiving means receives the earthquake prediction data and generates an output representing the earthquake prediction data, and the determination means receives the earthquake prediction data from the receiving means. Based on the output, it is determined that the earthquake is predicted, and based on this determination, the inflator is driven by the driving means to release gas and flow into the airbag.

  Along with this, the airbag is deployed so as to be annular toward the inner surface in the living room. Therefore, the living room is held by the airbag from the inside so as to maintain the original shape. As a result, even if a large earthquake that collapses a house arrives, the house can be protected without collapse by maintaining the original shape of the room in a timely manner. It can be properly protected by the deployed airbag. Moreover, since the household goods in the living room can be held in the living room without falling by the airbag deployed in a ring shape, the human body is not damaged by the falling of the household goods.

According to a second aspect of the present invention, there is provided the seismic protection device according to the first aspect, wherein the airbag is supported outside the gas discharge device in a folded state on both sides in the lateral direction. Both side airbag portions (20a, 20b), and a connecting airbag portion (20c) connected between the folded front end portions of the side airbag portions to communicate the side airbag portions with each other.
The two-sided air bag portions are supplied with the gas released from the inflator and are deployed together with the connecting air bag portions so as to form an annular shape toward the inner surface in the living room.

  According to this, since the airbag is configured by connecting the connecting airbag portions between the airbag portions on both sides, the airbag is in accordance with the inflow of gas from the inflator to the airbag portions on both sides. The gas is caused to flow toward the inside of the connected airbag portion through the insides of the airbag portions on both sides.

  For this reason, the airbag is deployed from both side airbag portions to the connecting airbag portion so as to form a ring around the gas release device. Along with this, the both-side air bag portions expand along the inner surface of the living room together with the connecting air bag portions so as to push the inner surface portion corresponding to the airbag out of the inner surface of the living room. As a result, the function and effect of the first aspect of the invention can be achieved more reliably.

  According to a third aspect of the present invention, there is provided the seismic protection device according to the first aspect, wherein the airbag is provided outside the gas discharge device as a free end portion with one of its both ends closed. While being supported in a folded state, the gas discharged from the inflator is introduced into the other end of the both ends, and is developed so as to form an annular shape toward the inner surface in the living room.

  Thus, even if one of the both end portions of the airbag is a free end portion, the airbag causes the gas to flow toward the free end portion as the gas flows in from the inflator. For this reason, the airbag is deployed so as to be annular toward the inner surface in the living room with reference to the gas release device. As a result, the function and effect of the first aspect of the invention can be achieved more reliably.

  In addition, the code | symbol in the bracket | parenthesis of each said means shows the correspondence with the specific means as described in embodiment mentioned later.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of a seismic protection device to which the present invention is applied. As shown in FIG. 1, the protection device is supported from below on the left side of the ceiling 11 in the living room of the house 10. The house 10 is built on the ground G.

  The protection device includes an airbag 20 and a gas release device 30. The airbag 20 is configured integrally with the gas release device 30 in the folded state as shown in FIG. 2, and the airbag 20 passes through the gas release device 30 as shown in FIG. 10 is supported on the left side of the ceiling 11 from below.

  As shown in FIG. 2, the airbag 20 integrally includes a left airbag portion 20a, a right airbag portion 20b, and a connecting airbag portion 20c that couples the left and right airbag portions 20a and 20b. Thus, it is formed with a predetermined airbag material. In the present embodiment, as the predetermined airbag material, a light and soft material such as a silicone-based coated cloth or a non-coated cloth is employed.

  The left and right airbag portions 20a and 20b are integrally formed with the connecting airbag portion 20c so as to communicate with each other through the inside of the connecting airbag portion 20c. The left airbag portion 20a is hermetically sealed at the base end portion 21 so as to communicate with the one side opening portion (not shown) formed in the bottom wall 31a of the casing 31 of the gas discharge device 30. The left airbag portion 20a extends from the base end portion 21 and is bent upward in an L shape along the bottom wall 31a and the left wall 31b of the casing 31, and then the left wall portion 20a It is folded so as to meander up and down on the left side of 31b.

  On the other hand, the right side airbag part 20b is connected to the other side opening part (not shown) formed in the bottom wall 31a of the casing 31 of the gas release device 30 at the base end part 22 thereof. After the right airbag portion 20b is extended from its base end portion 22 and bent upward in an L shape along the bottom wall 31a and the right wall 31c of the casing 31, the right airbag portion 20b is connected and supported in an airtight manner. It is folded so as to meander up and down on the right side of the right wall 31c.

  The connecting airbag portion 20c is integrally connected to the extended end portions of the left and right airbag portions 20a and 20b at both left and right end portions thereof, so that the left airbag portion 20a, the casing 31, and the right airbag are connected. It extends along each lower surface of the bag portion 20b. In the present embodiment, the airbag 20 is wound and held by the annular support band 20d together with the gas release device 30 so as to maintain its folded shape. Thereby, the airbag 20 and the gas discharge device 30 in the folded state are configured in a substantially rectangular parallelepiped shape. The annular support band 20d is formed of an appropriate material so as to break based on the initial inflating force when the airbag 20 starts to inflate.

  As shown in FIG. 2, the gas discharge device 30 includes a rectangular parallelepiped casing 31. The casing 31 includes a bottom wall 31a, a left wall 31b, a right wall 31c, an upper wall 31d, a front wall 31e, and a rear wall. 31 f has a rectangular parallelepiped shape, and is supported from below by the upper wall 31 d on the left side of the ceiling 11 in the house 10. Thereby, the gas discharge device 30 supports the airbag 20 on the left side of the ceiling 11 from below.

  Here, as described above, the one side opening and the other side opening are formed in the bottom wall 31a. The upper wall 31d protrudes somewhat upward from the upper portions of the left and right airbag portions 20a and 20b so as to facilitate support to the left side portion of the ceiling 11. The distance between the front wall 31e and the rear wall 31f (the width in the front-rear direction of the casing 31) is substantially the same as the width in the front-rear direction of the left and right airbag portions 20a, 20b.

  The gas release device 30 includes a receiving device 32, a signal processing circuit 33, a microcomputer 34, and an inflator 35. The receiving device 32 includes a receiving antenna 32a and a receiver 32b. The receiving device 32 receives earthquake prediction data transmitted from a broadcasting station BS (for example, a NHK broadcasting station) via the transmitting / receiving antenna BSa. The signal is received by the receiver 32b as a transmission radio wave via the antenna 32a, and the earthquake prediction data is output as a reception signal. The receiving antenna 32a is erected on the roof of the house 10 (see FIG. 1).

  Here, the broadcasting station BS receives the earthquake prediction data transmitted by radio waves from the Japan Meteorological Agency MA via the transmission antenna MAa via the transmission / reception antenna BSa, and receives the earthquake prediction data from the transmission / reception antenna BSa by radio waves. Send. In the present embodiment, the earthquake prediction data is transmitted from the Japan Meteorological Agency MA in order to predict the arrival of a large earthquake (for example, an S wave vibration of the large earthquake) that would cause the house to collapse.

  The signal processing circuit 33 processes the reception signal output from the receiver 32b and outputs a signal processing signal. The microcomputer 34 executes a computer program according to the flowchart shown in FIG. 4. During the execution, the microcomputer 34 performs arithmetic processing required for driving the inflator 35 based on the output of the signal processing circuit 33. . The computer program is stored in advance in the ROM of the microcomputer 34 so as to be readable.

  The inflator 35 is a gas built-in type inflator, and the inflator 35 is disposed in the casing 31. Under the control of the microcomputer 34, the inflator 35 generates high-pressure gas such as helium, argon or nitrogen filled in the pressure-resistant container (not shown) with the initiation of the initiation member (not shown). It is configured to discharge from the gas discharge port of the pressure vessel through the openings on the one side and the other side of the bottom wall of the casing 31 and into the left and right airbag portions 20a and 20b of the airbag 20. . The gas discharge port portion of the pressure vessel is in airtight communication with the openings on one side and the other side of the bottom wall of the casing 31.

  In the present embodiment configured as described above, the receiver 32b, the signal processing circuit 33, and the microcomputer 34 are connected to the house 10 with the start of residence of a person (hereinafter referred to as a resident M) with respect to the house. Electricity is supplied from a power source (not shown) and is continuously operated.

  The microcomputer 34 executes the computer program according to the flowchart of FIG. Accordingly, in step 40, it is determined whether or not earthquake prediction data has been input.

  At this stage, if the signal processing circuit 33 does not output the processing signal representing the earthquake prediction data, the earthquake prediction data has not been input to the microcomputer 34, and therefore NO is determined in step 40.

  If the signal processing circuit 33 outputs a processing signal representing the earthquake prediction data in such a repeated determination state, YES is determined in step 40. Accordingly, in step 41, an earthquake arrival prediction determination process is performed. In this great earthquake arrival prediction determination process, based on the determination of YES in step 40, it is determined that a large earthquake (especially S wave vibration) that would cause a house to collapse is predicted.

  Along with such determination, inflator drive processing is performed in the next step 50. In this inflator driving process, the inflator 35 is driven under the control of the microcomputer 34, and the high pressure gas is supplied from the gas discharge port of the pressure vessel to the one side of the casing 31 with the initiation of the initiation member. In addition, the air is discharged toward the left and right airbag portions 20a and 20b of the airbag 20 through the openings on the other side.

  Then, the high-pressure gas flows from the one side opening of the casing 31 into the left airbag portion 20a through the base end portion 21 and from the other side opening of the casing 31 to the right airbag portion 20b. It flows through the end 22.

  Along with this, the left and right airbag portions 20a, 20b break the annular support band 20d while inflating each other in the left-right direction by the respective inflowing high-pressure gases, and further expand in the left-right direction from this folded state. And develop.

  Here, since the protection device is supported on the left side of the ceiling 11 in the house 10 as described above, the distance between the upper part of the left wall 12 of the house 10 of the left airbag part 20a. Is shorter than the distance between the upper part of the right wall 13 of the house 10 of the right airbag part 20b.

  Accordingly, in the inflating process as described above, the left airbag portion 20a expands while extending downward along the inner surface of the left wall 12. On the other hand, the right airbag portion 20b expands while extending rightward along the lower surface of the ceiling 11, and further expands while extending downward along the inner surface of the right wall 13.

  Along with this, the connecting airbag portion 20c is inflated while being displaced downward. For this reason, as shown in FIG. 5, the airbag 20 is deployed so as to be annular toward the inner surface in the house 10. Thereby, the ceiling 11, the left and right walls 12, 13 and the floor 14 of the house 10 can be maintained in the original shape before the occurrence of the earthquake based on the above-described deployed shape of the airbag 20. As a result, when the S-wave vibration reaches the house 10 due to the occurrence of the large earthquake, the seismic intensity of the large earthquake, in particular, the seismic intensity of the S-wave vibration is high such that the building collapses (for example, a seismic intensity of 7 ), The house 10 can be maintained in the state before the occurrence of the earthquake without collapsing.

  When the airbag 20 is deployed as described above, the resident M sitting on the floor 14 as shown in FIG. 1 in the house 10 is pressed onto the floor 14 by the lower side of the airbag 20. The chest T is pressed against the inner surface of the right wall 13 by the right side portion of the airbag 20. Therefore, as described above, even if the seismic intensity of the incoming S wave vibration is high, the body of the resident M is satisfactorily protected by the airbag 20 without being damaged while lying on the floor 14. In addition, the chest T can be maintained in the state before the occurrence of the earthquake without falling down. Therefore, even if a household item is placed on the chest T, the household item does not fall from the chest T. Since the airbag 20 is formed of a light and soft material such as a silicone-based coated cloth or a non-coated cloth, even if the resident M is pressed by the airbag 20 as described above, the resident M The bag 20 will not be damaged.

  Further, since the airbag 20 expands and deploys quickly due to the rapid release of the high-pressure gas by the inflator 35, when the S-wave vibration reaches the house 10 as described above, the inflation and deployment of the airbag 20 is completed. is doing. Accordingly, each of the above-described operational effects can be reliably achieved.

In carrying out the present invention, the following various modifications are possible without being limited to the above embodiment.
(1) Unlike the above embodiment, the protection device may be supported on the upper part of the peripheral wall in the house 10, for example.
(2) Unlike the above-described embodiment, the airbag 20 may close one of the base end portions 21 and 22 of the left and right side airbag portions 20a and 20b to be a free end portion, or may be a connected airbag portion 20c. May be cut and closed at the center in the left-right direction, and each free end may be used. Alternatively, the connecting airbag portion 20c may be abolished, and the distal ends of the left and right airbag portions 20a, 20b may be closed to both free ends. It is good also as a part.
(3) The inflator 35 is not limited to the gas built-in inflator described in the above embodiment, and various inflators may be employed.
(4) In the above-described embodiment, as described above, since only the ward T is present in addition to the resident M in the living room of the house 10, the airbag 20 is almost the ceiling 11, left and right in the living room of the house 10. The air bag 20 extends along the floor 14 when, for example, some household items such as a table or a desk exist on the floor 14. Instead of expanding in such a manner, it may be developed along each upper surface of the above-mentioned several household goods and may be developed in a ring shape in a state of being separated from the floor 14.
