Description
本考案は、地震発生時に避難・退避するシェルターを兼ねたテーブル類に関するものである(本明細書で「テーブル類」とは、テーブル・机・デスク・作業台その他、四本以上の脚部を有し上部に天板を有するものを含む広い意味で用いる)。 The present invention relates to tables that also serve as shelters for evacuation and evacuation in the event of an earthquake (in this specification, “tables” refers to tables, desks, desks, work tables, and other four or more legs. It is used in a broad sense including those having a top plate on the top).
近時、日本各地で地震が多発しているし、大地震がいつ発生してもおかしくないとも言われている。地震発生時の被害、特に最も重要な人の身体・生命を守り人的被害を最小限にとどめるためには、各人が冷静に状況を判断し、行動することが大切であって、日頃から災害時の心構えを身につけておくことが必要である。 Recently, many earthquakes have occurred in various parts of Japan, and it is said that it is not strange when major earthquakes occur. In order to protect the damage caused by the earthquake, especially the most important person's body and life, and minimize human damage, it is important for each person to judge the situation calmly and act. It is necessary to be prepared for a disaster.
このような状況下で、各地方公共団体その他の公的機関等により、新聞・雑誌・インターネットその他等を通じて、「地震に備える−あなたを守る8つの行動」とか、「地震発生そのときどうする」とか、「地震から身を守る心構え」とかのタイトルの下に、各人に対する注意事項が公表されている。 Under these circumstances, local governments and other public institutions, through newspapers, magazines, the Internet, etc., “Prepare for earthquakes – 8 actions to protect you” or “What to do when an earthquake occurs” Under the title “Precaution to protect yourself from an earthquake”, notes for each person are published.
それらにれよれば、家庭・学校・会社等で屋内にいる場合に地震が起きた際には、天井・食器棚・書籍棚・キャビネットその他の落下物・転倒物等から身を守るために、まずは丈夫なテーブルや机等の下へ身を隠し、1分間程度は自分の身の安全を図るように、と奨励されており、特に幼稚園や学校等では子供たちに机の下へもぐり込んで退避・避難する訓練も行われている。 According to them, when an earthquake occurs when you are indoors at home, school, company, etc., in order to protect yourself from falling objects, falling objects, etc., ceilings, cupboards, bookshelves, cabinets, First of all, you are encouraged to hide yourself under a sturdy table or desk, and keep yourself safe for about a minute, especially at kindergartens and schools, and evacuate children under the desk.・ Evacuation drills are also conducted.
ところが、一般に従来のテーブル・机・デスク等では、例えば地震により家屋が倒壊した場合や大型の家具その他が転倒した場合等には、その際の上方からの圧力・衝撃力・外力でテーブル等が簡単に粉砕したり破損してしまうおそれがある。特に家屋倒壊時に上方から大きなガレキ等が落下すると、テーブル等は脚部が偏平状その他の横倒れ状態になって、その内下方に避難・退避していた人が圧死してしまうおそれがある。 However, with conventional tables, desks, desks, etc., when a house collapses due to an earthquake or a large piece of furniture falls, the table, etc. can be moved by pressure, impact force, or external force from above. There is a risk of being easily crushed or damaged. In particular, when a large rubble or the like falls from above when a house collapses, the legs of the table or the like are flattened or other sideways, and a person who has been evacuated or evacuated to the inside may be overwhelmed.
また地震の横揺れが激しい場合には、例えば老人・子供等の握力が強くない者がテーブル等の内下部へ避難・退避して脚部を掴んでいても、脚部が本来そのようなことを考慮して設計されていないので、側方へ放り出されてしまうことになる。そのため、地震時にテーブル類の内下部へもぐり込むことは、必ずしも安全・安心な避難・退避手段とは言えない現状にある。 In addition, if the earthquake rolls severely, for example, even if an elderly person or a child who does not have strong gripping force evacuates and evacuates to the inner and lower parts of the table etc. It is not designed in consideration of, so it will be thrown out to the side. For this reason, it is not necessarily safe and secure to evacuate and retreat into the lower part of the table during an earthquake.
他面、例えば専用の耐震シェルターを家屋内に設置しておくことも考えられるが、経済的に容易でないことは勿論のこと、平時にはそのシェルターが占める空間を自由に使えなくなるので、使用可能な屋内空間が狭くなってしまう。特に、必ずしも広くない一般の居住家屋で設置するのは、殆ど不可能と言える。また専用の耐震シェルターでなくても、強度面だけを考慮したテーブル・机・デスク等も考えられるが、平時に使用するものとして屋内に設置しておくには不似合いで、違和感があって相応しくない。 It may be possible to install a dedicated seismic shelter on the other side, for example, but it is not easy economically, and the space occupied by the shelter can be used freely during normal times. The indoor space becomes narrow. In particular, it can be said that it is almost impossible to install in a general residential house that is not necessarily large. Even if it is not a dedicated seismic shelter, a table, desk, desk, etc. that only considers strength can be considered, but it is unsuitable to install indoors as a normal use, and there is a sense of incongruity Absent.
それでも従来、例えば次のようなものが発明・考案されている。
イ)机・テーブル等の天板であって、中空構造の天板の内部に根太と補強部材を組み込んで天板の強度を増し、落下物に対して十分に耐えうる構造の天板としたもの。
B) A table top such as a desk or table that has a structure that can withstand falling objects sufficiently by incorporating joists and reinforcing members inside the top plate of the hollow structure to increase the strength of the top plate. thing.
ロ)地震用家具であって、天板の下方に位置して地震の際に避難者がつかまることができ、及び又は天板の強度を増大できるつかまり棒を設けたもの。
ハ)地震・火事・強盗等の避難緊急用机であって、着脱自在の天板と、一面だけ開口された耐熱・耐火性および耐水性を有する耐衝撃性壁面で構成される机サイズの堅牢な箱体と、開口面の縁に沿って周設されたパッキングと、箱体に摺動可能に取り付けられた開口面の寸法と同サイズの底浅の引き出し兼用開口蓋とから構成されると共に、引き出し兼用蓋が完全に箱体から引き出されると、箱体と引き出し兼用開口蓋との間に設けられたヒンジ機構によって90度回転して開口面をパッキングと共に密閉ロックされるようにしたもの。
ところが、上記イ)のものは、天板をいくら頑丈に造っても、脚部を含む全体が堅牢でないと、地震により家屋が倒壊した場合や大型の家具その他の転倒や落下物があった場合等には、その際の衝撃力・外力で脚部が押しつぶされたり横倒れして、内下方に避難・退避していた人が圧死する可能性がある。 However, in the case of (b) above, no matter how hard the top plate is made, if the entire body including the legs is not solid, if the house collapses due to an earthquake or if large furniture or other falls or fallen objects For example, there is a possibility that a person who has been evacuated or evacuated inward and downward may be overwhelmed by the legs being crushed or lying down due to the impact force or external force at that time.
また、上記ロ)のものは、上方から圧力や落下物による衝撃力・外力に対しては耐えられて、内下方の避難・退避者が保護されるとしても、側方には何の防御手段もないから、例えば落下物や転倒物が側方から飛び込んでくることが考えれ、避難・退避者が被害を受ける可能性がある。 In addition, the above-mentioned b) can withstand the impact force and external force caused by the pressure and falling objects from above, and even if the evacuation / retreater in the lower part is protected, there is no protective means on the side. Therefore, for example, a fallen object or a fallen object may jump in from the side, and the evacuation / evacuee may be damaged.
しかも、そこでのつかまり棒は、天板を下方から支持する役目も担っているため、十分な強度上から太いものになってしまい、例えば老人や子供のように力の弱い者には、手でしっかり掴まっていることができず、地震の大きな横揺れに際してはやはり外へ放り出されてしまうことが考えられる。 Moreover, the gripping rod there is also used to support the top board from below, so it becomes thick from the standpoint of sufficient strength. For example, for elderly people and children who are weak, It cannot be grasped firmly, and it may be thrown out in the event of a large roll of an earthquake.
さらに、上記ハ)のものは、火事・強盗・水害等にも対応するため堅牢な箱形状になっており、対応できる範囲が広い。しかし、箱形状の一面だけしか開口されていないから、地震が発生した非常時に、大きな揺れの中を開口した側まで移動して中へもぐり込む行動は容易ではない。 Furthermore, the above item c) has a robust box shape to cope with fire, burglary, flood damage, etc., and has a wide range of response. However, since only one side of the box shape is opened, it is not easy to move into the open side by moving in a large shake to the inside when an earthquake occurs.
また、開口面の縁に沿ってパッキングが周設されているため、平時の使用時に椅子の脚が内下方へ入り難く、椅子が外へ出たままになるから、椅子に座って何かをする机としては使い勝手が悪いし、平時にこの机が占めるスペースの他に椅子のスペースも必要になって、屋内が狭くなる。 In addition, since the packing is provided around the edge of the opening surface, it is difficult for the chair's legs to enter inward and downward during normal use and the chair remains outside. It is not easy to use as a desk to be used, and the space for this desk occupies a chair space in addition to the space occupied by this desk during normal times.
仮に、平時に引き出し兼用開口蓋を引き出した状態で机として使用するとすれば、天板のスペース以外に開口蓋のスペースが必要となるから、やはり平時には余分な空間が必要となり、非常時には有用であるとしても、特に日本家屋のように屋内空間が狭いところでは、設置しておくのは躊躇してしまう。 If it is used as a desk with the drawer / opening lid pulled out during normal times, it will require space for the opening lid in addition to the space for the top plate. Even if it exists, it is hesitant to install it especially in places where the indoor space is small, such as a Japanese house.
本考案は、人が屋内にいる場合に地震が発生した際に備える避難・退避空間のために、従来一般のテーブル類を利用することに伴う問題点や、専用の耐震シェルターやそれに類する物を設置することに伴う問題点の解決を課題として考案したものである。 The present invention eliminates the problems associated with the use of conventional tables for the evacuation / evacuation space provided when an earthquake occurs when a person is indoors, as well as a dedicated seismic shelter and the like. It was devised to solve the problems associated with installation.
即ち、本考案の目的は、屋内に設置しても外観上で違和感が無く、平時には通常のテーブル・机・デスク等として利用できるので、その設置空間が無駄にならず、また地震発生時に内下部にもぐり込めば、十分な強度で身の安全を守れると共に、横揺れが激しくても人が側方へ飛び出したり、落下物が外部から飛び込むことも防げるような、耐震シェルターを兼ねたテーブル類を提供することにある。 In other words, the purpose of the present invention is that there is no sense of incongruity even when installed indoors, and it can be used as a normal table, desk, desk, etc. during normal times. Tables that also serve as an earthquake-resistant shelter that can protect you with sufficient strength to keep yourself safe if you dig into the bottom, and prevent people from jumping out to the side even if the roll is severe, or falling objects jumping in from the outside. Is to provide.

Near the both sides of the lower part in the top plate 1, between the reinforcing upper horizontal bars 5 and 6 on the top board 1 side and the horizontal or vertical reinforcing bar 18 provided between the front and rear legs 2a and 2b. In the meantime, even if a large pressure is applied from above, the legs 2a, 2a, 2b, 2b are prevented from falling down, and a person who has evacuated or retreated to the inside or bottom of the top 1 is grasped to hold the position. A gripping member 11 that also serves as a reinforcement is provided.
In the present specification, the term “rectangular” is used to mean a right-angled quadrilateral shape including a square in addition to a rectangle.
上記構成に係る耐震シェルター兼用テーブル類Aは、次のような効果を奏する。
イ)平時は、屋内に設置して通常の通常のテーブル類として使用することができる。
即ち、このテーブル類Aは、上部の天板1下部の少なくとも四隅近傍に脚部2を有する構造で、平時は一般的なテーブル類と変わらず通常の使用ができると共に、屋内に設置してあっても何の違和感もない外観・構造である。そして、人が屋内にいる際に地震が発生した非常時には直ちに、身近かに設置してあるこの耐震シェルター兼用テーブル類Aの内下方へもぐり込んで、避難・退避することができる空間となる。
The seismic shelter combined table A according to the above configuration has the following effects.
B) During normal times, it can be installed indoors and used as a normal table.
That is, the table A has a structure having legs 2 near at least the four corners of the lower top plate 1 and can be used as usual during normal times and installed indoors. It has an appearance and structure without any discomfort. In the event of an earthquake when a person is indoors, the space immediately closes in and below the earthquake-resistant shelter-use tables A that are installed in the immediate vicinity, and becomes a space that can be evacuated and evacuated.
ロ)地震発生時に、この耐震シェルター兼用テーブル類Aの内下部へもぐり込めば、十分に身の安全を確保することができる。
即ち、このテーブル類Aは上部の天板1の裏面に補強用金属板3を張付し、その下面に金属杆製で矩形状の補強用枠体4を設けると共に、該補強用枠体4の各対辺間に金属製の補強用上部横杆5,6を設け、また両側の前・後脚部2間に金属製の補強用下部横杆7と金属製の防御用側板8とを各々固着し、かつ天板1側の補強用上部横杆5,6のいずれかと、前後の脚部2a,2b間に設けた横または縦方向の補強用杆18との間に、補強兼用の掴持部材11を設けてある。
B) If an earthquake occurs, it is possible to sufficiently secure the safety of the seismic shelter combined table A by entering the inner and lower parts.
That is, the table A has a reinforcing metal plate 3 attached to the back surface of the upper top plate 1, and a rectangular reinforcing frame 4 made of metal cage is provided on the lower surface thereof, and the reinforcing frame 4 Metal reinforcing upper side bars 5, 6 are provided between the opposite sides, and metal reinforcing lower side bars 7 and metal defense side plates 8 are provided between the front and rear legs 2 on both sides. A reinforcing and holding grip between any one of the reinforcing upper horizontal bars 5 and 6 on the top plate 1 side and the horizontal or vertical reinforcing bar 18 provided between the front and rear legs 2a and 2b. A holding member 11 is provided.
そのため、このテーブル類Aは頑丈で十分な強度を有する構造になっており、地震で例えば大型の家具類が転倒した場合は勿論のこと、家屋の倒壊で大きなガレキが落下してきたような場合でも、上記補強用金属板3によって天板1がバラバラに破損しまうことがないし、また補強用枠体4、補強用上・下 横杆5,6、補強兼用の掴持部材11により、テーブル類Aは頑丈にできており、脚部2が横倒れして押しつぶされてしまうようなことが無くなる。 For this reason, the tables A are strong and have a sufficient strength. For example, even when large furniture falls down due to an earthquake, even when a large rubble falls due to the collapse of a house. The top plate 1 is not broken apart by the reinforcing metal plate 3, and the table A is formed by the reinforcing frame body 4, the reinforcing upper / lower lateral ribs 5, 6, and the holding member 11 also used as a reinforcement. Is made so that the leg 2 is not crushed and crushed.
これにより、内下方へもぐり込んでいた人が怪我をしたり、圧死してしまう等の人命・身体に被害が及ぶことを防止でき、家屋内に設置する簡便な耐震用シェルターとして有効なものである。 As a result, it is possible to prevent damage to human life and body such as injuries or crushing of people who have entered the inside and below, and it is effective as a simple earthquake-resistant shelter installed in the house. .
ハ)この耐震シェルター兼用テーブル類Aは、上部に補強用金属板付きの天板1、その内下部の両側部に金属製の防御用側板8、前・後部にシャッター9を設けてあり、テーブル類Aの内下部へもぐり込んだ人は、これらによって囲まれた空間に避難・退避することなる。そのため、上方や前・後・左・右方向からの落下物の飛び込みを防止できるし、炎等からも身を守ることもでき、かつ地震の横揺れが大きい場合に外部へ放り出されることも、防御用側板8やシャッター10によって防止できている(例えば図3参照)。 C) This table A for earthquake-proof shelters has a top plate 1 with a reinforcing metal plate at the top, a metal side plate 8 on both sides of the inner and lower sides, and shutters 9 at the front and rear. A person who has entered the lower part of Class A will be evacuated and evacuated to the space surrounded by them. Therefore, it is possible to prevent falling objects from jumping in from the top, front, back, left and right directions, protect yourself from flames, etc., and be thrown out to the outside when the earthquake rolls greatly. This can be prevented by the protective side plate 8 and the shutter 10 (see, for example, FIG. 3).
ニ)さらに、この耐震シェルター兼用テーブル類Aは、天板1の内下方の両側寄りに、補強を兼ねた掴持部材11を少なくとも一対設けてある。そのため、天板1下方へもぐり込んだ人は地震が納まるまでの間、該掴持部材11を掴んでいることができる。この掴持部材11は、掴むことを予定したものであるから、例えば老人・子供等の握力が強くない者でもしっかりと掴持することができ、この点からも外側方へ放り出されずにテーブル類Aの内下方で身体の位置を保持して、身の安全を確保することができる(例えば上記図3参照)。 D) Further, the table A for earthquake-resistant shelters is provided with at least a pair of gripping members 11 that also serve as reinforcements on both sides of the upper and lower sides of the top plate 1. Therefore, the person who has entered the lower side of the top board 1 can hold the holding member 11 until the earthquake stops. Since the gripping member 11 is intended to be gripped, it can be firmly gripped even by a person who does not have a strong gripping force, such as an elderly person or a child. From this point, the table is not thrown outward. The position of the body can be held at the lower side of A to ensure safety of the body (for example, see FIG. 3 above).
ホ)このテーブル類Aに設けた前・後部の防炎布製のシャッター10は平時には巻き上げておけばよいので、天板1下方の前・後は常に開口されている。そのため、このテーブル類Aでは椅子や脚を前からでも後方からでも内下方へ入れて座ることができ、通常のテーブル類Aとして何の支障もなく使用することができるし、平時は椅子を内下方へ収納しておけるから、日本家屋のような比較的狭い屋内空間に設置しておいても、全く邪魔になることがない。 E) The front and rear shutters 10 made of flameproof cloth provided on the tables A need only be rolled up during normal times, so that the front and rear below the top plate 1 are always open. Therefore, in this table A, chairs and legs can be seated inward and downward from the front and back, and can be used without any trouble as a normal table A. Since it can be stored downwards, even if it is installed in a relatively small indoor space such as a Japanese house, it does not get in the way.
そして地震が発生した非常時に人は直ちに、前・後いずれの開口部からも容易・迅速にこのテーブル類Aの内下方へもぐり込むことができるし、またシャッター9を容易・迅速に引き下ろして閉じることができる(例えば図3・図4参照)。この際、各シャッター横杆14の両端の抜止め部材18がガイドレール9に係合・係止されてもいるので、シャッター9はスムーズに昇降すると共に外れることがなくなっている。そのため、屋内に設置して地震発生時に退避・避難できる屋内耐震シェルターとして十分にその役割を果たすことができる。 And in the event of an earthquake, a person can easily and quickly go in and out of the table A from both the front and rear openings, and the shutter 9 can be easily and quickly pulled down and closed. (See, for example, FIGS. 3 and 4). At this time, since the retaining members 18 at both ends of each shutter lateral ridge 14 are engaged and locked to the guide rail 9, the shutter 9 can be lifted and lowered smoothly. Therefore, it can play a role as an indoor earthquake-resistant shelter that can be installed indoors and evacuated and evacuated in the event of an earthquake.
へ)しかも、上記シャッター10は布製としてあるから、地震の揺れが納まった後は、例えばそれを切り裂いてでも外側方へ脱出することが可能である。そのため、避難・退避場所から脱出できずに逃げ後れたり、火災に巻き込まれるような事態も、このテーブル類Aでは避けることができる。 In addition, since the shutter 10 is made of cloth, it is possible to escape to the outer side even after tearing it, for example, after the shaking of the earthquake is settled. Therefore, the table A can also avoid situations where the user cannot escape from the evacuation / evacuation area and escapes or gets involved in a fire.
上記構成で、天板1の大きさ・形状は、この耐震シェルター兼用テーブル類Aの平時の使用目的が一般家庭用・学校用・事業所用のいずれなのか、また地震発生時の避難・退避者数等によって適切なものとすればよい。該天板1を含む各部の表面は、平時の使用状態に応じた色・装飾等を耐熱樹脂塗料等により表面加工をして、屋内で使用する家具・調度品類としても違和感の無いものにしておくことが望ましい。 In the above configuration, the size and shape of the top plate 1 is the purpose of use of the earthquake-resistant shelter-use table A during ordinary times for general home use, school use, and business use. It may be appropriate depending on the number. The surface of each part including the top plate 1 is surface-treated with a heat-resistant resin paint or the like according to the normal use condition so that it does not feel uncomfortable as furniture and furniture used indoors. It is desirable to keep it.
脚部2は、このテーブル類Aが例えば2人用としてならば、天板1の四隅から下方へ設たものでよいが、2人以上用で横長状のテーブル類Aならば、長手方向の中間位置等にも脚部2を設けておけばよい。脚部2の縦寸法は人がもぐり込めるように、天板1の下面までの高さが通常は約70cm程度は確保できるようにしておくのがよいが、このテーブル類Aの平時の用途によっても若干の相違があるのは当然である。 The leg 2 may be provided downward from the four corners of the top plate 1 if the table A is for two people, for example. However, if the table A is for two or more people and is horizontally long, The leg 2 may be provided at an intermediate position or the like. The vertical dimension of the leg 2 should be such that the height to the lower surface of the top board 1 is usually about 70 cm so that a person can crawl. Of course, there is a slight difference.
また該脚部2、補強用枠体4、補強用上部横杆5,6、補強用下部横杆7、補強用杆18等の金属材は、強度を考慮して例えばスチール製の中空金属製にすることが望ましい。防御用側板8や、さらには補強用三角板16も、強度を考慮してスチール製とするのがよい。 Further, the metal material such as the leg 2, the reinforcing frame 4, the reinforcing upper horizontal ribs 5 and 6, the reinforcing lower horizontal rib 7 and the reinforcing vertical flange 18 is made of, for example, a hollow metal made of steel in consideration of strength. It is desirable to make it. The defense side plate 8 and further the reinforcing triangular plate 16 are preferably made of steel in consideration of strength.
また前・後部のシャッター10,10の本体部分は破れ難い強度と共に防炎性を有する材質を用いるものとし、かつ作動部は公知の巻上げ式スクリーン(ロールスクリーン)と類似の構造であって、上部にコイルバネを利用した巻き上げ機構と、下方へ引き下ろした状態で係止可能なストッパー機構を備えたものにしておくのがよい。 The body parts of the front and rear shutters 10 and 10 are made of a material that is hard to tear and has flame resistance, and the operating part has a structure similar to a known roll-up screen (roll screen), It is preferable to provide a winding mechanism using a coil spring and a stopper mechanism that can be locked in a state of being pulled down.
上記補強兼用の掴持部材11は、このテーブル類Aの大きさ・長さに等によっても本数が異なるし、内下部へもぐり込む人の数に応じたものにしておけばよいが、テーブル類Aの内下部で各側で1本ずつ設けてもよいし(例えば図1・図4参照)、2本ずつ設けてもよい(例えば図8参照)。また幼稚園・学校・事業所等の多数人が集まる場所では、このテーブル類Aを複数台並べて用いればよい(例えば図9参照)。 The number of the reinforcing and holding members 11 varies depending on the size and length of the table A, and the number may be determined according to the number of people who go into the lower part. One may be provided on each side in the lower part (see, for example, FIGS. 1 and 4), or two may be provided (see, for example, FIG. 8). In addition, in a place where a large number of people gather, such as kindergartens, schools, and business establishments, a plurality of these table types A may be used side by side (see, for example, FIG. 9).
図1ないし図7は、本考案に係る耐震シェルター兼用テーブル類Aの実施例を示すが、ここでは一般家庭用のもので、2人が避難・退避可能な構成にしたものである。 FIGS. 1 to 7 show an embodiment of the earthquake-resistant shelter combined table A according to the present invention.
