Description

Background of the invention

[0001] The invention relates to a fire protection device, in particular a mobile one, and a transport vehicle with such a fire protection device.

[0002] Thanks to electromobility, more and more vehicles on the road are at least partially electric. They therefore typically contain a considerable battery, typically based on lithium-ion batteries, which, however, are highly flammable and particularly difficult to extinguish. If such a vehicle catches fire, it cannot be extinguished with conventional means such as water. It is therefore common practice to allow the vehicle to burn down in a more or less controlled manner. The fire often spreads to neighboring vehicles or at least damages them.

[0003] A fire can also spread to neighboring vehicles, which in turn ignite the batteries, setting the adjacent vehicles on fire and thus triggering a further fire spread to the adjacent vehicles. This is especially true if these vehicles are also electrically powered.

[0004] DE 10 2022 112 506 A1 discloses an extinguishing arrangement for a vehicle that surrounds the respective vehicle in such a way that extinguishing agent is deployed in a confined space, flooding the source of the fire with the extinguishing agent. The vehicle is parked on a parking area, and a wall arrangement can be erected around the vehicle, which can laterally enclose the vehicle in a required position. The extinguishing agent can be accommodated in the enclosed area in order to flood the vehicle with the extinguishing agent. The wall arrangement is recessed into the parking area in a standby position and can be pushed vertically into the required position.

[0005] DE 10 2021 133 101 A1 discloses a bulkhead assembly for flooding a room. The bulkhead assembly comprises a bulkhead element with sealing elements at lateral interfaces and a floor interface. The bulkhead element is connectable to an infrastructure to seal the room and flood it with an extinguishing agent. The bulkhead element has a drain opening that is variably adjustable along a height of the bulkhead element. Object of the invention

[0006] It is an object of the invention to provide an improved fire protection device and an improved transport vehicle for such a fire protection device. In particular, it is an object of the present invention to provide a particularly safe fire protection device that can prevent or at least reduce the spread of a fire to neighboring vehicles. Description of the invention

[0007] This object is achieved according to the invention by a fire protection device according to claim 1 and a transport vehicle according to claim 10. The dependent claims represent preferred developments.

[0008] The object of the invention is thus achieved by a fire protection device comprising a fire protection base wall, a first fire protection side wall and a second fire protection side wall, wherein the first fire protection side wall and the second fire protection side wall are pivotally attached to the fire protection base wall such that the first fire protection side wall and the second fire protection side wall can be pivoted from a first state in which the first fire protection side wall and the second fire protection side wall are arranged parallel to the fire protection base wall, into a second state in which the first fire protection side wall and the second fire protection side wall are arranged perpendicular to the fire protection base wall, and wherein the first fire protection side wall and the second fire protection side wall are further arranged on the fire protection base wall such thatthat the first fire protection side wall and the second fire protection side wall can each be displaced in the second state counter to the pivoting direction, perpendicular to the fire protection base wall and parallel to one another, wherein the first fire protection side wall and the second fire protection side wall are further arranged on the fire protection base wall in such a way that they can be displaced in the second state counter to the pivoting direction, perpendicular to the fire protection base wall and parallel to one another and / or the first fire protection side wall and the second fire protection side wall are designed as telescopic side walls which can be expanded, preferably in the second state, in particular counter to the pivoting direction, perpendicular to the fire protection base wall and parallel to one another, wherein counter to the pivoting direction means opposite to the direction in which the first fire protection side wall and the second fire protection side wall are in the second state.

[0009] The fire protection device according to the invention is used in particular for fire protection and firefighting of vehicles, in particular electric vehicles. However, it is understood that all embodiments described below can also be used equally for other burning objects, such as garbage cans, emergency power generators, or accumulators, in particular objects that have similar or smaller dimensions than a conventional vehicle. However, for the sake of simplicity, reference will only be made to one vehicle below. The size can, however, be adapted as needed. For example, outdoor parking spaces for parked or charging electric buses could also be protected by the fire protection device according to the invention, as will be explained in more detail below.

[0010] The fire protection device according to the invention serves, in particular, to extinguish a fire in a vehicle that is igniting or has already caught fire, and further, in particular, to prevent or reduce the spread or spread of the fire to one or more neighboring vehicles. In particular, the fire protection device according to the invention can be deployed near or in parking lots and / or parking garages, especially underground garages, in order to quickly reach the scene of the incident. These can, in particular, be areas or sections where charging stations for charging a vehicle are provided.

[0011] For this purpose, the fire protection device according to the invention initially comprises a fire protection base wall, a first fire protection side wall, and a second fire protection side wall. The fire protection base wall and the fire protection side walls are in particular made of a fire-resistant, fire-repellent, and / or flame-reducing material and / or have such a coating. On the other hand, the material of the fire protection base wall and the fire protection side walls should be sufficiently lightweight, since the fire protection device should be transportable to the fire site, as will be explained in more detail in connection with the exemplary embodiments.

[0012] The fire protection base wall and the fire protection side walls have an essentially rectangular shape and a greater height and width than depth or thickness.

[0013] The first fire protection side wall and the second fire protection side wall are pivotally attached to the fire protection base wall such that the first fire protection side wall and the second fire protection side wall can be pivoted from a first state in which the first fire protection side wall and the second fire protection side wall are arranged substantially parallel to the fire protection base wall, into a second state in which the first fire protection side wall and the second fire protection side wall are arranged substantially perpendicular to the fire protection base wall.

[0014] In the first state, the first fire protection side wall and the second fire protection side wall are thus substantially parallel to the fire protection base wall. In particular, the first fire protection side wall and the second fire protection side wall have a substantially equal wall area. Further, in particular, the first fire protection side wall and the second fire protection side wall have a substantially smaller area than the fire protection base wall, or the fire protection base wall projects beyond the first fire protection side wall and the second fire protection side wall in height, wherein the first fire protection side wall and the second fire protection side wall have a substantially similar width to that of the fire protection base wall, at least in a non-expanded state, as will be described below.

[0015] In the second state, however, the first fire protection side wall and the second fire protection side wall are arranged substantially perpendicular to the fire protection base wall. To this end, the first fire protection side wall and the second fire protection side wall are pivotally mounted to the respective left and right outer edges or the wall edge of the fire protection base wall in such a way that they can be pivoted or folded away from the wall surface of the fire protection base wall until the wall surfaces of the first fire protection side wall and the second fire protection side wall form a right angle to the wall surface of the fire protection base wall.

[0016] In particular, the first fire protection side wall and the second fire protection side wall can pivot continuously along a quarter-circle arc away from the wall surface of the fire protection base wall. Furthermore, in particular, the first fire protection side wall and the second fire protection side wall cannot pivot more than 90° away from the fire protection base wall or its wall surface. This can be prevented, for example, by a stop connected to the base wall at a right angle.

[0017] In particular, the first fire protection side wall and the second fire protection side wall are arranged on the fire protection base wall in such a way that they successively reach the second state. In particular, the one of the first fire protection side wall and the second fire protection side wall that is further away or spaced from the fire protection base wall in the first state is first transferred from the first state to the second state.

[0018] According to the invention, the first fire protection side wall and the second fire protection side wall are further arranged on the fire protection base wall in such a way that the first fire protection side wall and the second fire protection side wall can each be displaced in the second state counter to the pivoting direction, perpendicular to the fire protection base wall and parallel to each other.

[0019] In this case, "opposite the pivoting direction" means opposite to the direction in which the first fire protection side wall and the second fire protection side wall are located in the second state. This enables parallel displacement of the first fire protection side wall and the second fire protection side wall perpendicular to the fire protection base wall, in particular perpendicular to the wall surface of the fire protection base wall, to which the first fire protection side wall and the second fire protection side wall were arranged parallel in the first state.

[0020] The base protective wall and the fire protection side walls thus form a cuboid closed on three sides, which, in particular together with a floor, a ceiling and a rear wall, further in particular in or of a parking garage, forms a rectangular space or cavity that is essentially closed on all sides, in particular completely, in which a burning vehicle can be arranged and can burn down in a controlled manner.

[0021] According to the invention, the first fire protection side wall and the second fire protection side wall are designed as telescopic side walls which can be expanded, preferably in the second state, in particular counter to the pivoting direction, perpendicular to the fire protection base wall and parallel to each other.

[0022] In this context, "expanding" means that the first fire-resistant side wall and the second fire-resistant side wall can expand, meaning they can increase their surface area. In particular, the first fire-resistant side wall and the second fire-resistant side wall can increase their width through a telescopic function. This can occur both before and after the first fire-resistant side wall and the second fire-resistant side wall are moved perpendicular to the fire-resistant base wall.

[0023] For this purpose, the first fire protection side wall and the second fire protection side wall can consist of at least two, in particular at least three, further in particular exactly three, telescopic wall elements, which are arranged at least partially one inside the other, in particular in a non-expanded state or before expansion, and the respective inner telescopic wall element is moved out of the outer telescopic wall element.

[0024] In particular, the fire protection device is designed such that an expansion of the first fire protection side wall and the second fire protection side wall is only possible when the first fire protection side wall and the second fire protection side wall have reached the second state, i.e. are each arranged perpendicular to the fire protection base wall.

[0025] Furthermore, in particular, the height of the fire-resistant base wall and / or the fire-resistant side walls can be dimensioned such that it complies with certain fire protection regulations, in particular to provide an escape route and / or rescue route. The height here refers to both the design without the telescopic wall element and, in the latter case, the height with the telescopic wall element in the expanded state.

[0026] The invention therefore provides a compact and therefore easily transportable fire protection device which can be easily and quickly transported to the site of use at the source of a fire and which can there completely enclose the source of the fire in just a few steps and thus bring it under control.

[0027] In one embodiment, the fire protection base wall can alternatively or additionally be designed as a telescopic wall comprising several telescopic wall elements and can be expanded along its height and / or width. The fire protection base wall can have the same properties and / or configurations as described in connection with the fire protection base walls. In particular, the fire protection base wall can be expanded from a single parking space width to a double parking space width, in particular from, for example, 2.00 m to 4.00 m or from 2.50 m to 5.00 m.

[0028] In one embodiment, the fire protection device is arranged on a first guide rail and designed to be moved thereon.

[0029] The guide rail can be arranged, in particular, on the ceiling of a parking garage, and the fire protection device can be suspended vertically downwards and movably mounted thereon. In particular, the guide rail can be arranged perpendicular to several parking spaces, and the fire protection device can thus be mounted so that it can be moved perpendicularly thereto.

[0030] This design makes it possible to provide a single fire protection device for multiple parking spaces, which can then be quickly moved along the guide rail to the fire location. In particular, this provides a mobile fire protection device that can be easily guided to the scene of the fire.

[0031] In one embodiment, the fire protection device is additionally arranged on a second guide rail which is arranged parallel to the first guide rail and is designed to be displaced thereon.

[0032] In this particular embodiment, in particular, the fire protection base wall as well as the first fire protection side wall and the second fire protection side wall can be arranged not substantially perpendicular to the floor or ceiling in the first state, but rather parallel to it, movably attached to the two guide rails. In particular, the side of the fire protection base wall facing away from the first fire protection side wall and the second fire protection side wall can be movably attached to the two guide rails.

[0033] For this purpose, the first fire protection side wall and the second fire protection side wall can be pivoted downwards from the fire protection base wall towards the floor and assume a position perpendicular to it. For this purpose, the fire protection base wall can also have a third fire protection side wall, which in the first state is also arranged parallel to the fire protection base wall and to the first fire protection side wall and second fire protection side wall, but pivots over a different edge of the fire protection base wall and thus, in the second state, is arranged perpendicular to the fire protection base wall and also perpendicular to the first fire protection side wall and second fire protection side wall, thus forming the third wall perpendicular to the floor or ceiling.

[0034] In this embodiment, the first, second and third fire protection side walls can also be designed as telescopic walls, as described above, whereby these can expand in particular downwards, towards the floor or down to the floor.

[0035] This design is particularly suitable for parking garages with high ceilings and / or little wall space, so that the fire protection device can be arranged in a particularly space-saving manner.

[0036] In one embodiment, the fire protection device further comprises an extinguishing unit configured to provide an extinguishing agent. For this purpose, the extinguishing unit comprises, for example, an extinguishing agent reservoir and / or an extinguishing agent dispensing element, such as a nozzle or an outlet, from which the extinguishing agent can be dispensed, in particular into the cavity formed by the fire protection device or its walls or the motor vehicle located therein. In particular, the extinguishing agent is an extinguishing agent that is particularly suitable for extinguishing electric vehicles and / or batteries or accumulators, such as a special extinguishing foam or carbon dioxide.

[0037] This design makes it possible not only to control the fire but also to actively extinguish it.

[0038] In one embodiment, the fire protection device further comprises a connecting element configured to receive an extinguishing agent supply element for supplying extinguishing agent. The extinguishing agent supply element is, in particular, a fire hose, and the connecting element is a corresponding connection. The connecting element can be provided alternatively or in addition to the previously described extinguishing unit.

[0039] This design also makes it particularly easy to actively extinguish the fire.

[0040] In one embodiment, a receiving element for a smoke extraction hose can be additionally formed in the fire protection base wall, dimensioned according to requirements. The smoke extraction hose can either be permanently attached to the fire protection base wall or, once fully expanded, can be moved separately using the rail system.

[0041] In one embodiment, the movement from the first to the second state and / or the parallel displacement of the first fire protection side wall and the second fire protection side wall and / or the parallel expansion of the first fire protection side wall and the second fire protection side wall and / or the displacement on the first and / or second guide rail takes place with the aid of a drive.

[0042] For this purpose, the fire protection device can comprise one or more drives, in particular electric drives. These can be powered either by a wired mains connection or by a battery or accumulator included in the fire protection device. For this purpose, the accumulator or batteries can be arranged, in particular, on the fire protection base wall. Furthermore, in particular, the accumulator can be powered or charged by a mains connection and, as soon as the fire protection device is triggered, i.e., moves, can be disconnected from the mains connection, and the movement can then be powered exclusively by the accumulator. The drives can, in particular, be designed as servomotors.

[0043] This results in a particularly fast, reliable and safe movement of the fire protection side walls in relation to the fire protection base wall and also of the fire protection device as a whole in relation to the vehicle.

[0044] In one embodiment, the movement from the first to the second state and / or the parallel displacement of the first fire protection side wall and the second fire protection side wall and / or the parallel expansion of the first fire protection side wall and the second fire protection side wall and / or the displacement on the first and / or second guide rail takes place in response to a fire detection.

[0045] For this purpose, the fire protection device can comprise or have access to a fire detector, such as a smoke and / or fire alarm, and / or a thermal imaging camera. In particular, the fire protection device can be connected to a fire alarm system of a parking garage and / or a fire department control center and thus be informed of a fire. In particular, the fire protection device can also be designed to independently control a fire location within the movement radius. For this purpose, the fire protection device can comprise or have access to control elements.

[0046] This results in a particularly independent and safe fire protection device that can quickly detect a fire and bring it under control.

[0047] In one embodiment, the fire protection device further comprises a receiving element that is designed to be received by a transport vehicle and moved thereby. In particular, this embodiment is an alternative embodiment to the embodiment that is attached to one or more guide rails, as described above. Instead, this embodiment can be, in particular, a mobile fire protection device that is not rail-guided, but rather is stored at a location designated for this purpose and can be picked up by a transport vehicle and brought to the fire site if necessary.

[0048] For this purpose, the fire protection device has a receiving element that can be received by a corresponding receiving element of a transport vehicle or can be attached thereto, in particular detachably. The transport vehicle can be a forklift truck, and the receiving element of the fire protection device can be a receptacle corresponding to the fork, into which the forklift truck can engage. However, the receiving element can also be a trailer coupling receptacle or similar, through which the fire protection device can be attached to a transport vehicle for transport.

[0049] This enables a particularly mobile fire protection device. This design is particularly suitable for urban areas or open parking lots where there are no walls or ceilings to attach the fire protection device to. Alternatively, a rail-guided design can still be used in urban areas or open parking lots, with the guide rail(s) being arranged, in particular, on a structure consisting of support columns.

[0050] The first fire protection side wall and / or the second fire protection side wall can be vertically telescopic (when the fire protection device is installed). In particular, the first fire protection side wall and / or the second fire protection side wall can be upwardly telescopic (when the fire protection device is installed).

[0051] The object of the invention is also achieved by a transport vehicle comprising a fire protection device according to one of the previously described embodiments.

[0052] In particular, it is a fire protection device with a receiving element, as described above, wherein the fire protection device is detachably arranged on the transport vehicle. Alternatively, the fire protection device can also be permanently connected to the transport vehicle, for example, welded thereto or at least partially formed integrally therewith. In particular, the transport vehicle can also comprise one or more control elements by which the transport vehicle and, in particular, a passenger of the transport vehicle can control functions of the fire protection device, in particular movement of the fire protection side wall and / or the fire protection base wall relative to each other.

[0053] In one embodiment, the transport vehicle is an autonomous vehicle. Autonomous, in this case, means a vehicle that can drive without human intervention and thus move to the fire scene with exceptional safety and independence.

[0054] Alternatively, the transport vehicle may be a remote-controlled vehicle, which can be controlled in particular by a central unit such as a fire alarm control centre and / or a fire brigade.

[0055] Further features and advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any desired manner.

[0056] In the figures, the same reference symbols denote the same or similar features.

[0057] Fig. 1a shows a plan view of a first embodiment of a fire protection device 10 in a first position.

[0058] The Fig. The exemplary embodiment shown in Figures 1a to 6b shows a fire protection device 10 that is arranged perpendicularly and / or vertically to a floor, in particular a garage floor. In particular, the fire protection device 10 is arranged in a space that is at least partially enclosed, such as in a parking garage or an underground garage.

[0059] These in the Fig. 1a and Fig. The position of the fire protection device shown in Figure 1b can also be referred to as the rest position. In this position, the fire protection device 10 is not in use and does not serve as a fire protection device.

[0060] In particular, the fire protection device 10 is arranged in a space-saving manner.

[0061] In the Fig. In the embodiment shown in Figures 1a to 6b, the fire protection device 10 is arranged along a single upper guide rail 20, in particular suspended, and slidably attached thereto. Additionally, a second, lower guide rail may be provided, which is in particular embedded in the ground, but which is not shown in this embodiment. The guide rail 20 is arranged perpendicular to several parking spaces and runs essentially parallel to a respective parking space end of the adjacent parking spaces or perpendicular to a parking position of a vehicle.

[0062] In the event of a fire, the guide rail 20 allows the fire protection device to be moved toward a parked vehicle 1, thereby limiting and, if necessary, extinguishing the fire source located there. In particular, the fire protection device 10 can be moved from the rest position to an operational position, as will be explained in connection with the following figures.

[0063] The fire protection device 10 is in this Fig. 1a and Fig. 1b, which can also be referred to as the folded state, is arranged such that it has a maximum extension in the width B and a minimum extension in the depth T. This is achieved by the fire protection device 10 being arranged in this state such that a first fire protection side wall 200 and a second fire protection side wall 300, which are pivotally attached to a fire protection base wall 100, are arranged in a folded state, namely such that the first fire protection side wall 200, the second fire protection side wall 300 and the fire protection base wall 100 are arranged substantially parallel to one another along the width B of the fire protection base wall 100 or thereon, as described in connection with the following Fig. 1b. In particular, the first fire protection side wall 200, the second fire protection side wall 300, and the fire protection base wall 100 are all arranged perpendicularly or vertically to the floor.

[0064] Fig. 1b shows a perspective view of the fire protection device 10 from Fig. 1a.

[0065] In this case, Fig. 1b shows how the fire protection device 10 is arranged suspended from the single upper guide rail 20. Likewise, Fig. 1b shows how the first fire protection side wall 200 and the second fire protection side wall 300 are arranged in a folded state parallel to the fire protection base wall 100.

[0066] The fire protection device 10 is displaceable along the guide rail 20, in particular parallel to the width B of the fire protection device 10 and can be moved in the event of a fire towards the vehicle 1 along the guide rail 20, as described in connection with the following Fig. 2a to 6b will be described.

[0067] The first fire protection side wall 200 and the second fire protection side wall 300 are designed as telescopic side walls, as will be explained in more detail in the following figures, and can therefore also be referred to as the first telescopic side wall and the second telescopic side wall.

[0068] Fig. 2a shows the fire protection device 10 from Fig. 1a in a second position. This second position can also be referred to as the deployment position. The fire protection device 10 remains in the folded state.

[0069] The fire protection device 10 has been moved along the guide rail 20 toward the vehicle 1 into the deployment position and arranged behind or in front of it. In particular, the fire protection device 10 has been moved toward the vehicle 20 such that both a left edge 101 and a right edge 102 of the fire protection device 10, in this position or this state, which can also be referred to as the folded, retracted, or closed state, project beyond the vehicle in terms of their lateral dimensions. In other words, the fire protection device 10, in this state, is essentially as wide as a typical parking space and / or not significantly wider than a typical motor vehicle, for example 2.30 m, 2.40 m, 2.50 m, or 2.60 m.

[0070] Fig. 2b shows the fire protection device 10 from Fig. 1b in the second position or a perspective view of the fire protection device 10 from Fig. 2a.

[0071] In this Fig. 2b it is evident that the fire protection device 10 in this folded state projects beyond the vehicle with both the left edge 101 and the right edge 102, thus having a width B which is wider than the vehicle 1. Also evident in this Fig. 2b, that a lower edge 103 of the fire protection device 10 is substantially flush with the ground.

[0072] The fire protection device 10 also has a viewing element 105 arranged in the fire protection base wall 100. The viewing element 105 can be formed either as a recess or in the fire protection base wall 100 or as a transparent element, for example made of Plexiglas, in particular of a fire-resistant or fire-resistant material. The viewing element 105 is arranged above the first fire protection side wall 200 and the second fire protection side wall 300, so that even in the Fig. 1a, Fig. 1b and 2a, 2b, a view of the motor vehicle 1 is not obstructed.

[0073] Fig. 3a shows the fire protection device from Fig. 2a in a first intermediate state. In contrast to Fig. 2a, the first fire protection side wall 200 is partially unfolded. It has thus been moved from a substantially parallel arrangement to the fire protection base wall 100 and the second fire protection side wall 300 into an arrangement angled thereto. Fig. 3a shows that the first fire protection side wall 200 has angled or moved away from the vehicle.

[0074] Fig. 3b shows a perspective view of the fire protection device 10 from Fig. 3a. Here, too, it can be seen that the first fire protection side wall 200 in this first intermediate state shown here continues to be arranged perpendicularly or vertically to the ground, but is angled relative to the fire protection base wall 100 and the second fire protection side wall 300.

[0075] This in the Fig. 3a and Fig. The state shown in Figures 3b and 4a and 4b is an intermediate state on the way or the transfer of the fire protection device 10 into a second state, as will also be explained below.

[0076] Fig. 4a shows the fire protection device 10 from Fig. 2a in a second intermediate state. The first fire protection side wall 200 is fully unfolded, while the second fire protection side wall 300 is still not.

[0077] In this second intermediate state, the first fire-resistant sidewall 200 is arranged substantially at a right angle to the fire-resistant base wall 100 and the second fire-resistant sidewall 300. The first fire-resistant sidewall 200 has been pivoted about an axis substantially coincident with the right edge 102, to a point where the fire-resistant sidewall 200 is arranged substantially perpendicular to the fire-resistant base wall 100.

[0078] Fig. 4b shows a perspective view of the fire protection device 10 from Fig. 4a. Here, too, it can be seen that the first fire protection side wall 200 in this second intermediate state shown here continues to be arranged perpendicularly or vertically to the ground, and is also arranged perpendicularly to the fire protection base wall 100 and the second fire protection side wall 300.

[0079] Fig. 5a shows the fire protection device 10 from Fig. 2a in a second state. This second state can also be referred to as the unfolded state. In this state, both the first fire protection side wall 200 and the second fire protection side wall 300 are arranged perpendicular to the fire protection base wall 100. The second fire protection side wall 300 has also passed through the state shown in Fig. 3a and Fig. 3b, in which it is temporarily arranged at an angle to the fire protection base wall 100.

[0080] The second fire protection side wall 300 was similarly pivoted about an axis which essentially coincides with the left edge 101 of the fire protection device 10, also outwards, away from the vehicle 1.

[0081] In this state, the first fire protection side wall 200 and the second fire protection side wall 300 are arranged substantially parallel to each other and oriented perpendicularly to both the fire protection base wall 100 and the ground.

[0082] Fig. 5b shows a perspective view of the fire protection device 10 from Fig. 5a. Here, too, it can be seen that, in addition to the first fire protection side wall 200, in this second state shown here, the second fire protection side wall 300 continues to be arranged perpendicularly or vertically to the floor and is now also arranged perpendicularly to the fire protection base wall 100.

[0083] Fig. 6a shows the fire protection device 10 from Fig. 2a in a third state. The first fire protection side wall 200 and the second fire protection side wall 300 were displaced further from the second state, opposite to the pivoting direction, perpendicular to the fire protection base wall 100 and parallel to each other.

[0084] In particular, this Fig. 6a that the first fire protection side wall 200 and the second fire protection side wall 300 are designed as telescopic side walls which, in the second state, can be expanded counter to the pivoting direction, perpendicular to the fire protection base wall 100 and parallel to each other.

[0085] For this purpose, the first fire-protection side wall 200 has a first telescopic wall element 210, a second telescopic wall element 220, and a third telescopic wall element 230, and the second fire-protection side wall 300 also has a corresponding first telescopic wall element 310, a second telescopic wall element 320, and a third telescopic wall element 330. It is understood that both more and fewer than three telescopic wall elements can be provided, in particular exactly two or more than three.

[0086] In particular, sufficient telescopic wall elements can be provided so that the first fire-protection side wall 200 and the second fire-protection side wall 300 can be extended or expanded to such an extent that the desired length or expansion can be achieved under given stability criteria. For example, for larger motor vehicles, such as trucks with trailers, five or ten or more telescopic wall elements can be provided, which are in particular higher and shorter than those shown here for a normal motor vehicle.

[0087] The telescopic wall elements of the respective fire protection side wall are arranged one inside the other and can be moved parallel to one another along the depth T. It is also evident that the first fire protection side wall 200 and the second fire protection side wall 300 have been moved so far parallel to one another and perpendicular to the fire protection base wall 100 that they both only protrude slightly beyond the fire protection base wall 100 in the direction opposite to the direction of movement into the depth T.

[0088] In an embodiment not shown, the fire protection base wall is alternatively or additionally designed as a telescopic wall and is in particular designed to be expanded along the width B. For example, the fire protection base wall can be enlarged from a width of 2.00 m to a width of 4.00 m, in particular doubled, in order to cover two parking spaces along the width B.

[0089] Fig. 6b shows a perspective view of the fire protection device 10 from Fig. 6a. The Fig. 6a and Fig. The state shown in Figure 6b represents the final state, which can also be referred to as the end state. In this state, the fire protection base wall 100, the first fire protection side wall 200, and the second fire protection side wall 300 with their telescopic wall elements, the rear wall, the floor, and a ceiling (not shown) of the garage form a substantially completely enclosed cavity that completely encloses the vehicle 1. If the vehicle 1 is on fire, it can be safely and controlledly burned out by the fire protection device 10 without endangering nearby vehicles.

[0090] In addition, in the Fig. In the embodiments shown in Figures 1a to 6b, a fire protection ceiling wall can be provided which provides further fire protection below the ceiling - also not shown - in particular for installation lines arranged directly below the ceiling, such as electrical wiring.

[0091] The fire protection ceiling wall can be arranged, in particular, on the fire protection base wall, in particular on an upper edge, and extend, for example, along the depth, essentially perpendicular to the fire protection base wall and parallel to the ceiling or floor. The fire protection base wall can also optionally be designed as a telescopic wall, which is designed to expand along the depth. Likewise, one or more additional guide rails can be provided for this purpose, which extend perpendicular to the first guide rail and support and / or guide the fire protection ceiling wall or its telescopic elements.

[0092] In particular, one or more additional guide rails can be arranged on the fire protection side walls and enable or support an expansion of the fire protection ceiling wall essentially simultaneously with the fire protection side walls. Likewise, a guide element can be provided that additionally supports and / or guides or stabilizes the fire protection ceiling wall or its telescopic elements during expansion. This embodiment enables a particularly closed fire protection device that can be used particularly well with a smoke extraction system.

[0093] Fig. 7a shows a perspective detailed view of the fire protection device from Fig. 5a in the second state. Fig. 7b shows a perspective detailed view of the fire protection device from Fig. 7a in a third intermediate state. Fig. 7c shows a perspective detailed view of the fire protection device from Fig. 7a in a fourth intermediate state. Fig. Figure 7d shows a perspective detailed view of the fire protection device from Fig. 7a in a fifth intermediate state.

[0094] These show in the Fig. 7a to 7d show in particular the movement sequences of the first fire protection side wall 200. Fig. 7a starts from the second state, as in Fig. 5a. From there, the first telescopic wall element 210 is initially moved parallel to the second fire protection side wall 300 and parallel to the other telescopic wall elements of the first fire protection side wall 200 as well as perpendicular to the fire protection base wall 100, which is Fig. 7b is shown.

[0095] In an embodiment not shown, in which the fire protection base wall is also designed as a telescopic wall, the expansion of the fire protection base wall, in particular along the width, can be carried out before the Fig. 7a shown second state and further in particular according to the Fig. 2a and Fig. 2b shown first state or from the one in Fig. 2a and Fig. 2b shown second position as a further intermediate state and only after the expansion of the fire protection base wall are the fire protection side walls pivoted and / or moved in parallel and / or expanded.

[0096] After the first telescopic wall element 210 has fully expanded, i.e. extended from within the second telescopic wall element 220 where it was previously located, the second telescopic wall element 220 is also expanded, i.e. extended, as shown in Fig. 7c can be seen.

[0097] After the second telescopic wall element 220 has also fully expanded, the third telescopic wall element 230 and thus the entire first fire protection side wall 200 is moved parallel to the second fire protection side wall 300 and perpendicular to the fire protection base wall 100.

[0098] It is understood that the second fire protection side wall 300 is also designed to assume this intermediate status, in particular simultaneously with the first fire protection side wall 200, but for reasons of clarity in these Fig. 7a to 7d is not shown.

[0099] Also on display are the Fig. 7a to 7d a guide element 211 which guides and supports the expansion of the first telescopic wall element 210 with respect to the second telescopic wall element 220.

[0100] Also in Fig. 7a to 7d, an extinguishing unit 130 is shown, which is designed to provide an extinguishing agent and a connection element 140, which is designed to receive an extinguishing agent providing element, such as a fire hose, in order to provide extinguishing agent, in particular to the cavity formed by the fire protection base wall 100 and the fire protection side walls as well as the ceiling, the floor and the rear wall, as described in connection with the Fig. 1a to 6d were explained.

[0101] Fig. Figure 8a shows a perspective view of an embodiment of the fire protection device 10 from Fig. 7a.

[0102] In this case, in Fig. 8a, the fire protection device 10 is not arranged on a guide rail, as in connection with Fig. 1a to 6b, but is designed to be mobile. For this purpose, the fire protection device 10 has a receiving element 150, which is arranged in particular on the wall surface of the fire protection base wall 100. The receiving element 150 is designed to be picked up by a transport vehicle 5 and thus moved. Fig. 8a, the transport vehicle 5 is designed as a forklift truck and the receiving element 150 is designed to correspond to the forks and can be detachably received therefrom.

[0103] Fig. Figure 8b shows a further perspective view of an embodiment of the fire protection device from Fig. 7a or shows Fig. 8b shows an alternative embodiment of a mobile fire protection device 10. The fire protection device 10 is connected to the transport vehicle 5, in particular in a non-detachable manner, or the fire protection device 10 is partially integral with vehicle components of the transport vehicle 5. Furthermore, the transport vehicle 5 is designed here as an example of an autonomously driving vehicle.

[0104] In both Fig. 8a and Fig. In the embodiments shown in Figure 8b, a driver and / or passenger of the transport vehicle 5 can see, identify, and precisely target the fire through the viewing element 5. Additionally, the fire protection device 10 is shown here in the second state, providing additional protection for the transport vehicle 5 against the fire. This allows the fire protection device 10 to be transported particularly safely.

[0105] Fig. 9a shows a perspective detailed view of an embodiment of a pivot element 110. The pivot element 110 comprises a first hinge element 111, a second hinge element 112, and a third hinge element 113, which pivotally connect the fire protection base wall 100 and the first fire protection side wall 200, as shown here by way of example. It is understood that more or fewer hinge elements can naturally be provided. Likewise, it is understood that the second fire protection side wall 300 can also be pivotally attached to the fire protection base wall 100 with one or more hinge elements, which are not shown for reasons of clarity.

[0106] The pivoting element 110 also comprises a hinge drive unit 115, which is connected via a shaft 114 to the first, second and third hinge elements and can drive them for a pivoting movement, as will be explained in connection with Fig. 9b will be explained in more detail.

[0107] Also in Fig. 9a shows the connection element 140, which is designed to receive an extinguishing agent supply element, such as a fire hose, in order to provide extinguishing agent.

[0108] Fig. 9b shows a detailed view of Fig. 9a. Here, the shaft 114 is shown in detail, which comprises a gear element 116 that engages with a gear receptacle 117 of the second hinge element 112 and thus causes a pivoting or movement of the first fire protection side wall 200 with respect to the fire protection base wall 100.

[0109] Fig. 10 shows another detailed view from Fig. 9a. In this Fig. 10 is in addition to the pivoting element 110, as in connection with Fig. 9a and Fig. As described in Figure 9b, a wall drive unit 240 is shown, which is designed to effect a movement of the first fire protection side wall 200 perpendicular to the fire protection base wall 100 and an expansion of the individual telescopic wall elements parallel to one another. It is understood that the second fire protection side wall 300 is also provided with a corresponding wall drive unit, which is not shown for reasons of clarity.

[0110] To move the fire protection side wall 200 and the telescopic wall elements, the wall drive unit 240 has a gear element 241 which engages with a corresponding rack element which extends over all three telescopic wall elements, as will be explained in connection with the following Fig. 11a, Fig. 11b and 12a, 12b will be explained.

[0111] Fig. 11a shows a side view of the first fire protection side wall 200 in the second state. In particular, the first telescopic element 210, the second telescopic element 220, and the third telescopic element 230 are still predominantly arranged within each other, as is also shown in the following Fig. 11b is shown.

[0112] As also in this Fig. 11a, the rack element 242 extends over the entire depth T of the fire protection side wall 200, i.e. over the first telescopic element 210, the second telescopic element 220 and the third telescopic element 230 and engages with the driven gear element 241. Also shown in Fig. 11a shows two locking elements which are encompassed by the first and second telescopic elements, respectively, and of which, for reasons of clarity, only one locking element 250 is provided with a reference numeral. The function of the locking element 250 will be explained in connection with Fig. 12a and Fig. 12n will be explained in more detail. If necessary, the locking element 250 can also be designed such that a projection (similar to an L-shaped rail) is attached along the height of each of the telescopic belt protection side walls, thereby locking the adjacent telescopic side wall elements.

[0113] Fig. 11b shows a cross-sectional view of the first fire protection side wall of Fig. 11a. It can be seen how the first telescopic element 210, the second telescopic element 220 and the third telescopic element 230 are arranged one within the other and how the rack element 242 engages with the gear element 241.

[0114] At the highest point or along an upper edge of the fire protection side wall 200, a telescopic rail (not shown) can be attached, which connects the adjacent telescopic elements 210, 220, and 230 to one another. This reduces resistance, while simultaneously stabilizing and supporting uniform expansion and ensuring the flush alignment of the telescopic elements 210, 220, and 230.

[0115] Fig. 12a shows the fire protection side wall made of Fig. 11a in the third intermediate state. In this figure, the first telescopic element 210 is fully extended, but the second telescopic element 220 is not yet extended. In this state, the Fig. 12b and locks the first telescopic element 210 to the second telescopic element 220, so that the rack element 242 is aligned between the first telescopic element 210 and the second telescopic element. At this moment, the gear element 241 engages from the rack element 242 of the first telescopic element 210 to the rack element 242 of the second telescopic element 220. This process is repeated when the second telescopic element 220 is fully extended and the gear element 241 engages from the rack element 242 of the second telescopic element 220 to the rack element 242 of the third telescopic element 230.

[0116] Fig. 13a shows a perspective view of another embodiment of the fire protection device 10 in the second position in the first state, corresponding to the one shown in Fig. 2b shown position and the condition shown there.

[0117] However, this differs from the Fig. In the embodiment shown in Figures 1a to 6b, the fire protection base wall 100 of the fire protection device 10 is not arranged perpendicular to the floor or ceiling, but parallel to them. For this purpose, the fire protection base wall 100 is attached to a first guide rail 20 and a second guide rail 30 on the ceiling and can be displaced parallel thereto along its width.

[0118] Fig. 13b shows the fire protection device 10 from Fig. 13a in an intermediate state, similar to that in Fig. 3b and 4b respectively. Fig. 13b shows that the fire protection device 10 not only has a first fire protection side wall 200 and a second fire protection side wall, which is not visible here for perspective reasons, but also a third fire protection side wall 400, which is also pivotally attached to the fire protection base wall 100, so that it can be pivoted from the first state, in which the third fire protection side wall 400 is arranged substantially parallel to the fire protection base wall 100, into a second state, in which the third fire protection side wall 400 is arranged substantially perpendicular to the fire protection base wall 100. In this second state, the third fire protection side wall 400 is then perpendicular to the fire protection base wall 100 as well as perpendicular to the first fire protection side wall 200 and the second fire protection side wall 300.

[0119] Fig. 14 shows the fire protection device 10 from Fig. 13a in the third, final state. It can be seen that the first fire protection side wall 200, the second fire protection side wall and the third fire protection side wall 400 are designed as telescopic side walls, which in the second state can be expanded counter to the pivoting direction, perpendicular to the fire protection base wall 100. The first fire protection side wall 200 and the second fire protection side wall 300 can be expanded parallel to each other and the third fire protection side wall 400 perpendicular to the first fire protection side wall 200 and the second fire protection side wall. For reasons of clarity, Fig. 14 only the first telescopic wall element 410, the second telescopic wall element 420 and the third telescopic wall element 430 of the third fire protection side wall 400 are provided with a reference symbol.

[0120] Deviating from the provisions of the Fig.In the embodiments shown in Figures 1a to 6b, there is no displacement of the first, second and third fire protection side walls perpendicular to the fire protection base wall 100 and parallel to each other, but they are merely expanded.

[0121] Taking all the figures of the drawing together, the invention relates, in summary, to a compact and therefore easily transportable fire protection device that can be easily and quickly transported to the site of use at the source of a fire, where the fire can be completely enclosed and thus brought under control in just a few steps. Both wall- and ceiling-mounted and mobile solutions have been specified, tailored to the respective application in parking garages, underground garages, open-air parking lots, and urban spaces.
