This application is a 371 of PCT/IB2011/000532, filed on Mar. 11, 2011, which claims priority to Italian patent application number PI2010A000027, filed Mar. 12, 2010, which is incorporated herein by reference.
The present invention relates to a protection cell made in the form of a table, bed, lifeboat or other similar structure, capable to protect a user and to assist rescue in case of earthquake phenomena or disasters of other kind. In particular, this structure can be used in public and private schools, offices, to conference rooms, railway stations, libraries, churches, hospitals, watercrafts, aircrafts etc.
A need is felt to minimize risks during and after catastrophic events such as earthquakes, floods or weather disasters, especially in crowded places is such as those above described.
During an earthquake, a fall of material, a partial or total collapse of structures, break of glasses and windows, fall of closets, furniture or other objects, are in most cases the reason of casualties.
As well known, in the last years buildings or houses of new conception have been built, in industrialized countries, with anti-seismic criteria. However, many regions in the world are particularly exposed to earthquakes and have insufficiently protected buildings, as well as furniture and objects in the buildings are free of moving and are not enough fixed to the buildings. So, where the buildings are old or in any case not adapted to bear the thrusts of earthquakes, since it is not possible, in the short time, to replace or reinforce the buildings with anti-seismic criteria, it is however possible to modify the objects, tables, beds, chairs, shelves, etc. (since they can be reason of casualties). Such aspect becomes of particular importance in public places such as public and private schools, offices, conference rooms, railway stations etc., wherein many people can be present. Even the anti-seismic structures, on the other hand, are capable of resisting in case of earthquake phenomena only up to a certain intensity, normally magnitude 7, whereas for extremely strong earthquakes they can also suffer serious damages.
Anti-seismic protection structures are known in the form of tables, beds and of other kind, which appear as furnishing in a building, in an office, in a school etc.
The most common types show a school or office desk of different size as described for example in JP2003310776A, CN201226987Y or in CN201210972Y, comprising an upper plane held with uprights of steel or wood or by a reticular open structure. The same structure that bears the desk defines a space within which at least one people can shelter in case of earthquake. Such structure provides, furthermore, in the shelter space, a kit of tools that can comprise for example a torch, a fire extinguisher or other tools, as described in CN201227483Y or in CN201243766Y.
As above said, however, the space located under the upper table desk is protected laterally only by uprights or by a reticular structure, and fragments of walls, objects or other debris can reach the user under the table shelter space.
This drawback is faced by other anti-seismic structures, as disclosed in JP11099217A, which have a box-like shape. In this case, an inner support frame is present that bears a plurality of boards arranged to cover it. Through an access door hinged to the structure, a user can access inside.
Such structure, however, has some drawbacks. Firstly, the access door, removable or hinged to the box-like structure at the aperture, is in the former case difficult to open/close quickly in case of need, whereas in the latter case it is always necessary to provide at least one hinged edge that reduces remarkably the size of the entrance and can block the user when entering quickly in the box-like structure.
Furthermore, such box-like structures do not ensure a fluid tight shelter space. Such causes gas, fluids or dust, formed by the collapse of walls or floors, to leak into the shelter space causing high risk on the safety of the user.
On the other hand, protection cells capable of protecting people in case of tsunami, landslide or flood disasters do not exist.
It is therefore a feature of the present invention to provide a protection cell that is structurally strong, but in the meantime light and handy, which can reduce casualties in disasters such as earthquakes, landslides, structural collapses, wars, as well as railway, car and aircraft crashes.
It is also a feature of the present invention to provide a protection cell which is made in an air-tight way, in order to give protection also against gas and powder.
Is also a feature of the present invention to provide a protection cell which is made in a liquid-tight way, in order to give protection also in case of tsunami, floods, shipwrecks.
Is also a feature of the present invention to provide a protection cell which is easy to use and cheap to manufacture on an industrial scale.
It is also a feature of the present invention to provide a protection cell which can ensure functionality in different conditions and that can be quickly retrieved by rescuers.
These and other objects are achieved by a protection cell comprising:
In particular, said container is produced as a single block with the shape of said open box-like container, which defines the inner shelter space for receiving the user.
In particular, said sliding cooperating element is arranged to engage with at least one slide path mounted on said upper wall or lower wall or on at least one side wall of said box-like container, such that the box-like container and the movable wall portion are adapted to move from an open configuration, where the movable wall portion opens said opening, to a closed configuration, where said movable wall portion blocks said opening, defining said protection cell.
This way, by the sliding cooperating element the movable wall portion remains always connected to the box-like container, such that the opening is closed quickly and easily in case of calamity such as an earthquake.
Preferably, said sliding cooperating element is a sliding plane board integral to said movable wall portion that slidingly engages between at least two guides, which are arranged at opposite sides with respect to each other on said box-like container.
Preferably, said slide path is arranged on said lower wall such that said sliding plane board faces towards the above or below with respect to said lower wall of said protection cell. In particular, this exemplary embodiment forms a structure substantially “drawer-like” where the movable wall portion remains always connected to the box-like container by the sliding plane board. This way, a quick closure of the movable wall portion is assisted. Furthermore, is in the open configuration the entrance space for the user to access the shelter space is wider with respect to, for example, an opening where the movable wall is hinged to the side wall. In this case, in fact, side edges for making the hinges would be necessary that reduce the size of the opening and create an obstacle to the entrance of the user.
Advantageously, at said opening a sealing means is provided adapted to ensure a fluid tight engagement of said box-like container in said closed configuration. This way, the protection cell prevents dust, liquid or gas, from leaking into the shelter space, ensuring a total protection to the user.
In particular, said sealing means comprises at least one groove, in particular a groove with tapered cross section, that is arranged to couple with a respective sealing element, so that, in said closed configuration, said sealing element engages with said groove, in order to form a labyrinth sealing. The prismatic shape of the matching allows a self-centering engagement of the movable element with respect to the fixed parts during the closure.
In particular, said groove is obtained at said movable wall portion, whereas said sealing element is arranged at an edge of said opening.
Alternatively, said groove is obtained on said edge of said opening, whereas said sealing element is arranged on said movable wall portion.
In a preferred exemplary embodiment, two grooves are provided parallel to each other that engage with two corresponding sealing elements, in particular gaskets of rubber or other material.
Advantageously, said movable wall portion comprises an end portion which protrudes upwardly with respect to said upper wall of said box-like container, in particular between said end portion and said movable wall portion a weakened zone is defined. This way, the end portion which protrudes above, in the closed configuration, with respect to the box-like container forms a protruding edge that assists the fluid-tight connection of the movable wall with respect to the container. Furthermore, the weakened zone that divides the end portion with respect to the movable wall portion allows that, if a heavy debris hits the end portion it breaks in the weakened zone, absorbing energy as energy of break, limiting the propagation of the hit to the remainder of the movable wall that would cause, for example, a partial opening of the protection cell.
Advantageously, a lock means is provided, in particular of mechanical type, which is arranged near said opening in such a way that, in said closed configuration, a releasable locking is obtained between said movable wall portion and said box-like container.
In particular, said lock means is a quick releasable click closure comprising a clasp element and a fastening element that are arranged to engage with each other, in order to provide a releasable connection.
Advantageously, said clasp element and said fastening element are arranged respectively near said opening and near said movable wall portion, or vice-versa. This way, the user from the inside of the shelter space in the closed configuration of the protection cell can engage the clasp element with the respective fastening element obtaining a steady closure of the movable wall portion with respect to the box-like container.
Advantageously, said protection cell provides at least one air vent arranged at one of said walls. In particular, air vents are provided on each side wall.
Advantageously, said air vent is a vent that can be opened manually and comprises a plurality of apertures adjacent to each other, and a closure portion sliding by means of a guide, that is arranged to open/close completely or partially said apertures. This way, the user can adjust an inlet and outlet air flow into/from the protection cell.
In addition, said protection cell provides at least one check valve for the flow of air from the inside towards the outside of the protection cell. In particular, a check valve is provided on each wall of the protection cell as well as on said movable wall portion.
In particular, said check valve is mounted at a respective hole and comprises a dome-shaped coating element having a plurality of holes, in particular arranged perimetrally, and a stopper connected to said dome-shaped coating element by means of an elastic element, such that when in to said protection cell the pressure is identical or less than the external pressure, said stopper remains in a normally closed position to stop said hole, whereas when in said protection cell the pressure is higher than the external pressure said stopper disengages from said hole and allows an inlet and outlet air flow.
This way, the rescuers have the time for determining from the outside the is position of the protection cell and the user can remain inside owing to the supply of oxygen, communicating with the outside.
Advantageously, a survival kit is provided arranged within said shelter space of the box-like container, said survival kit comprising for example parts such as:
an oxygen cylinder;
a means for determining the position of said protection cell, in particular a GPS detector in addition to a sender/receiver,
a utility/emergency light;
first-aid kit and long term food kit.
This way, the parts present in the kit allow to supply oxygen to the person in the protection cell by the oxygen cylinder, to make as far as possible comfortable the stay inside by the emergency light in addition to determine the position of the protection cell by a position detector.
In particular, the above described protection cell is made in the form of modules to contain a single user, that can be assembled, to provide different structures such as a table desk, a dining room table, a single bed, a double bed, etc.
In a first particular exemplary embodiment, said protection cell is a modular portion which is made in the form of a table and comprises a sitting board pivotally connected to the inner edge of the movable wall portion and that is arranged to move from a rest configuration, where the sitting board is substantially parallel to the movable wall portion, to a use configuration, where said sitting board is substantially orthogonal to the movable wall portion, so that a user can sit on it. This way, in the open configuration of the protection cell, the user can sit on the sitting board arrangement with legs within said shelter space of the box-like container and use the upper wall as desktop. Alternatively, an auxiliary table can be mounted on the upper wall such that the protection cell, according to the invention, acts as lower support. When the protection cell is used as table for example as school desk, in case of earthquake, more than one air vent can be opened, if the dangerous parts are solid (bricks, debris, etc.).
In a second exemplary embodiment, the protection cell is a modular portion which is made in the form of a bed, and in this case, the opening is is made on the edge along the cell. In this case, by assembling at least one module it is possible to form an upper wall as the size of a single bed or double bed.
In a third exemplary embodiment, the protection cell is a modular portion which is made in the form of lifeboat that can be used in watercrafts or alternatively, in case of flood, or other calamity in the presence of liquid. In this case, when the protection cell is used as lifeboat or in case of flood, tsunami, it has to be closed hermetically outwards. In this case the person can breath inside by the oxygen cylinder and by the check valves, until the cell does not achieve a stable position. For example if the cell is involved in a flood, or in case of tsunami, it can roll and/or translate dragged by the water up to reaching a stable position. During the movement the cell has to be closed hermetically and the sheltered person can breath with the oxygen and check valves. When the cell stops in a substantially steady position the person can breath through the air vents, that can be opened manually, which allow the inlet and the outlet of fresh air.
In a fourth exemplary embodiment, the protection cell is a modular portion which is made in the form of a fuselage or portion of fuselage of an aircraft in which a cabin is obtained within which the passengers can be accommodated.
In a fifth exemplary embodiment, the protection cell is a modular portion which is made in the form of cabin of a vehicle, in particular of a car that defines the cabin within which the passengers and the driver can be accommodated.
In a sixth exemplary embodiment, the protection cell is a modular portion which is made in the form of carriage or portion of carriage of a train or underground train.
In particular, the box-like container and the movable wall portion are made of a composite multi-phase, stratified and fibrous material. The material to is resistant, light and formable, as well as structurally capable of resisting to relevant loads such as those due to collapse of floors and/or walls. Furthermore, the above described material resists correctly to fire and to explosions in which the cell can be involved.
The invention will be now shown with the following description of some exemplary embodiments, exemplifying but not limitative, with reference to the attached drawings in which:
finally,
With reference to
In particular, protection cell 100 comprises an upper wall 1 and a lower wall 2 spaced with respect to each other through a plurality of side walls 3 integrally connected to each other, in order to form substantially a open box-like container 10 with at least one opening or entrance opening 4. Box-like container 10 defines inside a shelter space 11 that is arranged to accommodate at least one user 150, visible in
In particular, container 10 can be made by assembling the walls to each other, but preferably is produced as a single block that reproduces the open box-like container 10, for example for injection moulding or for rotational moulding.
The anti-seismic cell 100 comprises, furthermore, a movable wall portion 20 cooperating with box-like container 10 that is arranged to block opening 4. In case there are more apertures 4, as shown in
Always with reference to
In particular, in an exemplary embodiment, as shown in
Plane sliding board 25 thus arranged allows movable wall portion 20 to move from an open configuration A (
The exemplary embodiment of

In particular, as diagrammatically shown in
In particular, movable wall portion 20 comprises an end portion 23a that protrudes upwards with respect to the plane defined by upper wall 1 of box-like container 10. In particular, protruding end portion 23a is defined by a weakened zone 23, as shown in
To provide a hermetic closure of movable wall 20, furthermore, a lock member 40 is provided, in particular of mechanical type, which is located in box-like container 10 (
This way, once approached movable wall portion 20 to opening 4, user 150 can acts from inside on lock members 40 that are easy and fast to operate and ensure an effective closure of movable wall portion 20, and a full insulation with the labyrinth sealing.
Further characteristic of protection cell 100, according to the invention, relate to air vents 60 (as shown in
In particular, each air vent 60, as shown in
In particular, apertures 63 are inserted within a sealing frame 64 comprising a protruding seal member that touches closure portion 61 when this is overlapped to apertures 63, in order to make, also in this case, a hermetic closure. Air vents 60 allow the user to breath and let air pass from the outside. If this is not possible in box-like container 10 at least one oxygen cylinder 51 is provided (
In addition, on side walls 3 at least one check valve 70 (
In particular, each check valve 70 is mounted at a respective hole 75 and comprises a dome-shaped coating element 71 with a plurality of holes 72, in particular arranged perimetrally, and a stopper 74 connected to the dome-shaped coating element 71 by a resilient element 73, for example a spring. In detail, hole 75 has bent side walls 75a, whereas stopper 74 has a substantially tapered shape, in order to ensure a fluid tight engagement with hole 75 (
In particular, protection cell 100, as shown in
Furthermore, by connecting each other two or more modules it is possible to obtain a double bed, as shown in
In a further exemplary embodiment, as shown in
The structure of protection cell 110 described above, related to the structure of box-like container 10 and of movable wall portion 20 in the closed configuration B, can bear high loads, resistant to fire and to explosions owing to the features of the material with which they are made. The latter is, in particular, a composite material multi-phase, stratified and fibrous, for example a composite material such as carbon fibre on epoxy base, which fulfils the resistance, lightness and workability and then production cost relatively low with respect to the function that it develops.
Such a structure ensures a full protection on all the sides of the cell, improved with respect the known structures that ensure a protection, in most cases, only on the upper wall.
The parts present in survival kit 50 allow breathing in case of lack of oxygen in protection cell 100 by oxygen cylinder 51, of achieve a relatively comfortable stay inside by emergency light 52 in addition to determine the position of cell 100. This way, it is possible through receiver 54 to determine the position of the sheltered person in protection cell 100 as well as to transceive data from the outside and to assisting the first-aid treatment. Once in cell 100, the user can activate the breathing devices of survival kit 50 if the stay inside is long.
In particular,
