Description

  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).

  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.

  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.

  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.

  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.

  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.

  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.

Still, for example, the following have been invented and devised.
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.
Registered Utility Model No. 3026285

B) Earthquake furniture, which is located below the top plate and is provided with a grip bar that can be used by an evacuee in the event of an earthquake and / or increase the strength of the top plate.
Japanese Patent Laid-Open No. 10-5361

C) Evacuation emergency desk for earthquakes, fires, robberies, etc., which is a desk-size ruggedness that consists of a removable top plate and a heat-resistant, fire-resistant, and water-resistant shock-resistant wall that is open only on one side And a packing provided around the edge of the opening surface, and a shallow drawer / opening lid of the same size as the opening surface slidably attached to the box. When the drawer / lid is completely pulled out of the box, it is rotated 90 degrees by a hinge mechanism provided between the box and the drawer / open lid so that the opening surface is hermetically locked together with the packing.
JP-A-7-250713

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

Tables A that are also used as earthquake-resistant shelters according to the present invention are:
It has legs 2 near at least the four corners of the bottom of the top plate 1,
The top plate 1 has a reinforcing metal plate 3 attached to the back surface, and a metal reinforcing frame 4 is provided in a substantially rectangular shape near the periphery of the lower surface thereof. Between the opposite sides, metal reinforcing upper horizontal bars 5, 6 are provided,
The leg 2 is made of metal and has a vertical dimension that can secure a height that allows a person to crawl into the lower side of the top board 1, and between the front and rear legs 2 a and 2 b on both sides of the leg 2. In addition to the lower lateral ribs 7 for reinforcement near the lower part, respectively, the metal side plates 8 for defense are stretched,
Guide rails 9 are provided vertically between the left and right leg portions 2a, 2a, 2b, 2b at the front and rear, respectively, and both side ends of the shutter reed 14 are engaged with it and can be lifted and lowered. Each is provided with a roll-up shutter 10 made of a flameproof cloth that can be locked in a state,
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.

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.

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.

  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.

  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. .

  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).

  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).

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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).

  FIGS. 1 to 7 show an embodiment of the earthquake-resistant shelter combined table A according to the present invention. Here, the table A is used for general households and is configured so that two people can evacuate and retreat.

  The tables A are used as tables during normal times. As in the case of a normal table, the appearance has legs 2 in the vicinity of at least the four corners of the lower part of the top plate 1. Here, the top plate 1 is made of a wooden board having a thickness of about 3 cm, has a horizontally long shape with a width of about 160 cm and a front and rear width of about 100 cm, and has a shape in which the corners of the peripheral portion are eliminated. Further, here, the surface is subjected to surface processing with a heat-resistant resin coating.

  A reinforcing metal plate 3 is attached to the back surface of the top plate 2. This is because when the earthquake occurs, indoor furniture falls, other falling objects, houses collapse, etc., and when the top plate 1 is subjected to excessive pressure from above, it will break apart. This is to eliminate it. Here, an aluminum plate having a thickness of about 1.5 mm is pasted.

  A reinforcing frame 4 is provided near the periphery of the back surface of the reinforcing metal plate 3 as shown in FIG. The reinforcing frame 4 is formed in a substantially rectangular shape by connecting the four corners with postscript legs 2 using a hollow steel material having a thickness of about 2.3 mm and a longitudinal section of about 5 cm and a length of about 10 cm. The frame is fixed to the periphery of the back surface of the reinforcing metal plate 3. The reinforcing frame 4 is fixed to a lower portion of the top plate 1 through the reinforcing metal plate 3 by a plurality of L-shaped metal fittings 12 and bolts (see FIGS. 4 and 6). reference).

  Reference numerals 5 and 6 denote upper horizontal bars for reinforcement, which are fixed in a cross shape here so as to connect the opposite sides of the reinforcing frame 4 on the lower surface of the reinforcing metal plate 3 (see FIG. 4). Among them, the horizontal bar 5 in the longitudinal direction is a hollow steel material having a thickness of about 2.3 mm, a longitudinal section of 10 cm in width, and a height of about 5 cm. The transverse iron 6 in the short direction is a hollow steel material having the same thickness and a vertical cross section of 5 cm in width and about 10 cm in height. All of them are fixed to the lower surface of the top plate 1 and the reinforcing metal plate 3 with L-shaped metal fittings 12 and bolts, and each side end is fixed to the side surface of the reinforcing frame 4 with bolts.

  Here, the leg 2 is made of steel having a thickness of about 2.3 mm, and the cross section is a pentagonal hollow frame shape having a long dimension of about 11 cm and a short dimension of about 9 cm (see FIGS. 4 and 5). The length (height) is about 70 cm, and here, the reinforcing metal plate 3 is suspended from the four corners near the bottom of the top plate 1 lined. Here, the legs 2 are fixed to the top plate 1 and the reinforcing metal plate 3 in this case, the upper side portions of the respective leg portions 2a, 2a, 2b, 2b are connected to both side portions of the reinforcing frame 4 in the longitudinal direction. It is fixed to the lower part of the top plate 1 and the reinforcing metal plate 3 via the reinforcing frame 4 (see FIGS. 4 and 7).

  Of the above-mentioned leg 2, a left and right leg 2a, 2a on the left and right sides and a left and right leg 2b, 2b on the inside of the leg 2 are formed on the inner side here, The guide rails 9 and 9 for shutters, which are made of steel and have a U-shaped cross section, are fitted and fixed to each other (see FIGS. 1 and 5).

  Reference numerals 10 and 10 denote roll-up type shutters which are provided between the left and right leg portions 2a and 2a at the front part and between the left and right leg parts 2b and 2b at the rear part, respectively (FIG. 1). (See FIG. 4). Here, the shutters 10 and 10 are made by applying a flameproofing treatment to a thick polyester resin cloth, and the guide rails on the both sides of the shutter sides 14 and 14 provided horizontally on the lower edge portions. 9, 9 can be moved up and down.

  In other words, pipe-like shutter ridges 14 and 14 are attached to the lower end edges of the shutters 10 and 10, and stainless retaining members 15 and 15 having a U-shaped cross section are fixed to the respective side ends. The shutters 10 and 10 can be smoothly moved up and down by engaging with the guide rails 9 and 9 having a U-shaped cross section (see FIG. 5), and even when an external force is applied to the shutters 10 and 10, The flanges 14 and 14 are prevented from being detached from the guide rails 9 and 9.

  The structure of the operating part of the shutters 10 and 10 is the same as that of a known roll-up screen (roll screen), and the details are omitted. However, a roll-up mechanism (not shown) with a coil spring engaged with the horizontal axis, A stopper mechanism (not shown) that can be locked in a state where the reinforcing frame 4 is pulled down is provided in the case portions 13 and 13 at the front and rear portions of the reinforcing frame 4 (see FIG. 6).

  Further, between the front and rear legs 2a, 2b, 2a, 2b on both sides of the above-mentioned leg 2, the reinforcing lower horizontal ribs 7, 7 are laterally arranged near the lower part ( Here, a hollow steel material having a thickness of about 2.3 mm and a longitudinal section of about 5 cm wide × about 10 cm long is used. Between the reinforcing lower lateral ribs 7 and 7 and the upper reinforcing frame 4, here, protective side plates 8 and 8 made of steel plate having a thickness of about 1.6 mm are stretched in a double structure. (See FIGS. 1 and 3).

  Reference numerals 11 and 11 denote gripping members that also serve as reinforcements, and hold their own position so that a person who has evacuated and evacuated by entering into the lower part of the top plate 1 will not be thrown out to the outside due to the rolling of the earthquake. Here, one is provided near each side of the lower part in the top plate 1 (see FIG. 3). That is, here, a stainless steel pipe having an outer diameter of about 27.2 mm is bent into an L shape having a vertical portion of about 22 cm and a horizontal portion of about 35 cm, and the upper end of the pipe is elongated through a flange portion. It is fixed to both sides of the upper reinforcing rib 5a in the direction, and the side ends are fixed to the reinforcing ribs 18 and 18 provided between the double side defense side plates 7 and 7 with bolts. (See FIGS. 3 and 7).

  In addition, the gripping members 11 and 11 are not only gripped by a person who has evacuated and evacuated by entering inward and downward of the top plate 1, but also reinforce the fixing force between the top plate 1 side and the leg 2 side, The top plate 1 also serves as a reinforcement that prevents the leg 2 from falling down even if an excessive pressure is applied from above.

  Reference numerals 16 and 16 denote reinforcing triangular plates, which are fixed with bolts between the upper side surfaces of the leg portions 2a, 2a, 2b, and 2b and the lower surface of the reinforcing frame 4 (FIGS. 3 and FIG. 3). 4, FIG. 6 and FIG. 7), provided to further replenish the fixing force between the top plate 1 side and the leg 2 side. Here, a steel plate having an isosceles triangle shape having a thickness of about 5 mm and two sides sandwiching a right angle of about 20 cm is used, and a steel cover plate 17 having a thickness of about 1.6 mm so as to cover the outside. , 17.

  In the figure, reference numeral 19 denotes a leg non-slip member, which is made of synthetic rubber to prevent damage to the floor surface, and is fitted to the lower end of each leg 2. Reference numeral 20 denotes a shutter drawstring, which is attached to the shutter reeds 14 and 14 of the shutters 10 and 10 (see FIG. 1).
