DESCRIPTION OF PREFERRED EMBODIMENTS

Before explaining at least one embodiment in detail, it is to be understood that the embodiments are not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. It is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. In discussion of the various figures described herein below, like numbers refer to like parts. The drawings are generally not to scale.


For clarity, non-essential elements were omitted from some of the drawings.


Attention is drawn to FIGS. 1 to 5 that show an expandable safe room in accordance with a preferred embodiment. For a matter of convenience, the expandable safe room will hereinafter be called “ESR”.


It should be noted that directional terms appearing throughout the specification and claims, e.g. “forward”, “rear”, “upper”, “lower” etc., are used as terms of convenience to distinguish the location of various surfaces relative to each other. These terms are defined with reference to the figures, however, they are used for illustrative purposes only, and are not intended to limit the scope.


As shown in FIG. 1, an ESR 10 is provided that comprises a frame 12 onto which the various components of the system are mounted and assembled.


A major advantage of the ESR 10 is that in a folded position, as shown in FIG. 1, it has a minimal thickness dimension T thus occupying minimal space in an un-used position, so it may be covered, if desired, with a screening curtain or the like. According to a specific embodiment, in a folded position of the ESR 10, it has a thickness dimension T of about 28 cm. Typically, according to various sizes, uses and needs of the ESR, it has a thickness dimension T of 15 cm to 30 cm. Within the thickness T, almost all the components of the structure are folded; the walls, roof and floor are paralelly positioned within the thickness as well as all the pistons and connectors that facilitate the deployment of the structure.


The ESR 10 is self-standing, i.e., it is not dependable on any wall, bulkhead, frame, vehicle, or the like for maintaining it in an upright position. The frame 12 comprises a pair of lower substantially parallel rails 14 that are connected therebetween by a strengthening beam 16.


A main upright frame 18 having an inverted “U” shape, is vertically connected to the lower rails 14. The main upright frame 18 contains therein the expandable parts of the ESR 10 as will be later described.


A rear wall 20 of the ESR 10 (seen in FIG. 5) is located at a rear side 22 of the ESR 10. The rear wall 20, as well as all other plates forming the ESR 10 are made of steel and are able to withstand ballistic threats up to 7.62 caliber AP according to NIJ IV or Stanag 3. Other materials or combination of materials that can form similar strength of material can be utilized to implement the ESR. Each of the plates forming the ESR 10 is provided, in an inner portion thereof, with magazine rails into which protective panels may be inserted. The protective panels are capable to withstanding higher ballistic threats and are placed and classified according to customer's needs.


When it is required to open or deploy the ESR 10 into an operating position, as shown in FIG. 4, an operating system of the ESR 10 is operated. The operating system can be operated automatically, semi-automatically, or manually. In any case, the stages are similar.


In an automatic operation of the ESR 10, a controller 29 of the system optionally receives a signal from an external sensor (not shown in the figures). For example, in a case where it is required to use the ESR 10 as a protective shelter in an area that is susceptible to frequent earthquakes, a seismic sensor can sense that an earthquake is about the burst and signals the controller to immediately open the ESR 10. Thus, in a few seconds, the ESR 10 is open into an operating position and is ready to receive therein the people that have just sensed the earthquake, or, have been warned by the same sensor. The controller 29 can be located in any position on the ESR or in its vicinity, preferably hidden within the frame so no damage may be inflicted on it. It should be noted that the controller can receive communication to start deploying the ESR using a phone line or any other form of wired or wireless communication.


Another example of an automatic operation of the ESR 10 is when it is designed to deploy in a case of fire, in which case it will receive a signal from a fire detection system, or, in a case of burglary into a property, it will receive a signal from the corresponding intruder detector.


According to a specific embodiment, in a deployed position of the ESR 10, it has a length L of 270 cm, measured parallel to the main upright frame 18, a width W of 254 cm, measured perpendicularly to the length dimension L, and, a height H of 216 cm, measured perpendicularly to the length and width dimensions. When using the above described dimensions, the ESR 10 may accommodate therein eighteen people in a case of a need or emergency. Needless to say that other dimension of the ESR is possible according to needs wherein the ESR may accommodate different amounts of people.


A semi-automatically operation of the system means that a person, or a group of people in charge of the operation of the ESR 10, may press an operation button in order to commence deployment of the ESR 10. The operation button may be attached to the ESR 10, mechanically or wired, may be remotely located from the ESR 10, e.g., in other rooms or spaces, or, being operated by a remote controlled system that is not physically wired to the operation system.


A manual operation of the system means that a person manually operates a mechanism that deploys the ESR 10 from a folded position into a deployed position. This may be done, e.g., by rotating an operation handle which in turn operates an opening mechanism of the ESR 10.


In a first deployment step of the ESR 10, as can be seen in FIG. 2, a roof 24 is elevated to a horizontal positioning by a pair of roof operating pistons 26. The roof 24 is hinged by roof hinges 28 that are attached to the main upright frame 18. Thus, during the deployment of the roof 24, a roof forward end 30 executes a rising circular motion indicated by arrow 32 around the roof hinges 28. It should be mentioned that the roof 24 is elevated slightly above a horizontal positioning of the roof, for a reason that will be later described. In FIGS. 2 and 5, the cover of the upright frame is removed from the figures in order to be able to observe the piston mechanism in full.


According to a specific embodiment, the roof operating pistons 26 are electrical pistons, thereby having their own “positioning sensing system”, thus eliminating the need of using additional sensors for sensing the position of the various elements of the system.


When the roof 24 reaches its maximal lifted position, as shown in FIG. 2, the control system 29 (not shown in this figure) receives a signal to commence a second step of deploying the ESR 10. At this step, a pair of floor operating pistons 34 commence deploying a floor 36 that is fully exposed after the deployment of the roof. The floor 36 is hinged by floor hinges 38 that are attached to the main upright frame 18. Thus, during the deployment of the floor 36, a floor forward end 40 executes a lowering circular motion as indicated by an arrow 42 around the floor hinges 38 as shown in FIG. 3.


When the floor 36 reaches its final position, i.e., being fully deployed and parallel to the lower rails 14 (as shown in FIG. 3), the floor operating pistons 34 that are preferably also electrical, sense the positioning and signal the control system to commence a third step of deploying the ESR 10. At the end of this step, the removal of the roof and the floor of the frame expose the side walls of the ESR. At the following step as show in FIG. 4, a pair of wall operating pistons 44 opens forwardly in a forward direction indicated by arrow 48 a wall assembly 46. The wall assembly 46 comprises a pair of side walls 50 (only one side can be seen in FIG. 4) and a front wall 52 connected at a wall forward end 54 of the side walls 50.


Each of the side walls 50 comprises two sections, i.e., a side wall front section 56 and a side wall rear section 58 that are handedly connected therebetween by means of a vertically directed side hinge 60. The front wall 52 comprises a fixed portion 62 and a door 64 for enabling the entrance of people into the ESR 10.


In order to assure the forward advancement of the side walls 50 together with the front wall 52 in the proper direction, a lower front end 66 of each side wall front section 56 is connected to a lower rear end 68 of the adjacent side wall rear section 58 by means of an alignment mechanism 70. The alignment mechanism 70 comprises a set of two parallel front arms 72 that are hingedly connected to a set of two parallel rear arms 74. Thus, by means of the two sets of alignment mechanisms 70, oppositely located outward of the side walls 50, it is assured that the side walls 50 and the front wall 52 will move only in the forward direction as indicated by arrow 48, or, when retracted, in a rearward direction as indicated in arrow 76 that is opposite to the forward direction 48.


As mentioned herein before, at the first step, the roof 24 is elevated slightly above the horizontal position. When the front wall 52 and the side walls 50 reach their final position, as shown in FIG. 5 (with the roof removed for clarity), a wall operating piston 44 signals the control system to lower the roof 24 until it abuts against a wall upper end 78 of the front wall 52 and of the side walls 50.


Optionally, in this position, the side wall front section 56 and the side wall rear section 58 are not parallel and not forming a continuity of a straight line, but, forming an obtuse angle with respect to each other, around the side hinge 60 as seen in a top view of the side walls 50. This feature assures that, during a closing operation of the ESR 10, the side wall front section 56 is not locked with respect to the side wall rear section 58 and they can be easily folded with respect to each other, i.e., the obtuse angle therebetween is decreased and the side hinges 60 of the side walls 50 are moving toward each other. Generally, the ESR 10 can be folded in a similar manner as it was deployed. It should be mentioned that the roof has to be slightly elevated before the side and front walls are being folded.


Thus, an ESR such as ESR 10 is easily and efficiently erected, in a quick and safe manner, automatically or manually. Since the ESR 10 has a generally cubic or box shape and it is closed from all six sides thereof, it defines a protected space 80 therein and provides a safe room for people or equipment located therein.


Since the rear wall 20, the roof 24 and the floor 36 form an integral part of the ESR 10, the ESR 10 is very efficient in protecting the people inside also in a case of an earthquake, a missile attack, or even in a case of a total demolition of a building or structure it is located therein.


Optionally, part or all the hinges between the various walls are made such that the adjacent walls are provided with foldable or slidable overlapping parts so that there is no gap between the walls in their open position and they form a continuum of a protective case.


The ESR 10 may be delivered to a site either in an assembled position, as shown in FIG. 1, or, in a dismantled position, in which it is easier and lighter to transport, and then, the various parts are assembled on site.


In some optional embodiments of the ESR 10, the ESR may be provided with transparent elements such as windows of even larger transparent panels across a larger section of the walls. The windows may be ballistic proof and they may be formed from ballistic proof polycarbonate panels, as an example.


The ballistic protection of the ESR provides the people staying therein a wide spectrum of protection against terrorist threats, whether being a protection against fire arms, grenades, mortars blast fragments, or, against cold weapons.


Optionally, in a fire protection mode of the ESR, it is equipped with up to three hours of fire resistant materials that are implemented from the inside of the walls. It is optional that such protection will be implemented also to the roof and to the floor.


In a light-mode of the ESR, it may offer bullet-proof protection and can be installed in buildings, yachts, aircrafts, vehicles such as vans and buses, and the like.


It is a great advantage of the ESR that in a folded position, it has a relatively small thickness dimension; therefore, it can be installed in almost any location, without occupying much room during an unused period. Furthermore, in a folded position, it may be covered with a curtain or the like so it is not seen or noticed at all.


The ESR may be provided in a sealed or ventilated version, and it may also provide a humidity and temperature controlled environment. The ESR may be provided in an insulated or in a non-insulated mode.


Optionally, the ESR can be further provided with biological and chemical filtration systems that can be installed within the inner space of the ESR and include a special tent-style biological and chemical protection bubble or cover. The air filtration system is designed to filter bad odors or polluted air from entering into the protected area.


According to some embodiments, the ESR is provided with observation openings that may be blocked from inside and enable, if needed, outer observation and firing ability.


The control system and the operation system of the ESR are usually powered from the mains. However, as is the case of emergency, sometimes the mains power is not available. For that reason, some embodiments of the ESR are provided with a remotely starting generator and with an emergency battery supply voltage.


Although the present disclosure has been described to a certain degree of particularity, it should be understood that various alterations and modifications could be made without departing from the spirit or scope of the disclosure as hereinafter claimed. For example, the side wall front section does not have to form an obtuse angle with the side wall rear section, and they may form a straight angle therebetween. It that case, the side walls are further provided with a lock-breaking-device, to “break” the straight angle into an obtuse angle for enabling folding the side wall front sections with respect to their corresponding side wall rear sections.


The ESR is not limited to the sizes described above and other dimensions of the ESR may be equally applicable to suit different needs and different accommodation of people. Furthermore, the ESR can be installed indoors as well as outdoors.


The ESR does not have to be operated by electrical pistons and other drive means may be equally applicable as well. For example, the operation of the various parts of the


ESR may be through hydraulic or pneumatic pistons, or, it may be carried out by various mechanical driving mechanisms like gears, winches and cables, and the like.


The ESR is not limited to have its side walls having only two sections as described above. Alternatively, the side walls may contain higher number of sections, such as four or more. Typically, it is advantageous that the number of sections of the side walls be a pair number, thereby enabling easy opening and easy folding of the side walls as described above. In a case where the number of sections of the side walls is higher, then, it requires that the roof and the floor have a significantly larger width dimension. This may be achieved if the space available provides enough height for the ESR.


According to other embodiments, instead of producing the ESR with a very large height, the roof and the floor are also made of a multitude of sections that unfold as necessary.


The ESR is not limited to provide closing from six sides. At some embodiments, where the risk of earthquake is small, and where the floor and the roof of the building are made from a reinforced steel beams concrete, the ESR may be provided with a protection from four sides only which comprise the walls of the ESR. Furthermore, in a case where also a rear wall of the erection site of the ESR is made of solid reinforced concrete, the ESR may be provided with a protection of three walls only, i.e., the side walls and the front wall.


It is appreciated that certain features of the embodiments, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the embodiments, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub combination.


Although described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
