Definitions
- the present invention relates to a device for venting or ventilating a room, the room being delimited by walls, as for example in FIG US6405630 B described.
- a corresponding device is known from the prior art, for example from US Pat DE 20 40 285 .
- the grating is designed to be stable so that the air flow is not impaired by external influences and it is designed so that it can be walked on.
- the space that is to be vented or ventilated by the device according to the invention is delimited by walls and is therefore self-contained.
- an opening is provided in at least one of the walls, at which the air flow begins or ends.
- a ventilation system for generating an air flow is also provided.
- such a ventilation system can be a pipe or hose that connects the interior with the opening in the room.
- the air flow is then made possible by temperature differences inside the room compared to outside the room or also by different air compositions, for example different oxygen concentrations. It leads from the inside of the room through the pipe or hose to the opening.
- the air flow direction can be from the opening into the room or the other way around.
- the opening is covered according to the invention by at least three perforated plates.
- the perforated plates are arranged in layers next to one another and have two different degrees of hardness.
- the cover is thus designed in such a way that the device is designed to be accessible if, for example, the opening is arranged on the roof of the room and is protected against ballistic impact.
- This protection against ballistic effects is achieved in that, on the one hand, the perforated plates with the higher hardness ensure that ballistic effects do not even enter the opening and the perforated plate with the lower hardness ensures that the energy effect through the ballistic effect on the Device is compensated. This is achieved, among other things, in that the perforated plate with the lower hardness is deformed by such an action and thus absorbs the energy.
- the holes in the perforated plates can be designed as required. This allows larger holes to be used to allow greater air flow. However, the larger the holes, the less the protection that the device offers from external influences. By varying the hole size or the hole overlap, depending on the requirements, it is possible to vary between the greatest possible air flow and the greatest possible protection.
- the perforated plates consist of two different hardnesses, the outwardly directed perforated plate should have a high level of hardness. This is used to make the present device accessible and ensures that the room is protected as much as possible. The use of a material with a higher hardness ensures that the opening is securely covered and thus the space is largely completely limited by the walls and the device.
- the perforated plates with the higher hardness are made of armored steel. This has the advantage that when the device is introduced into an armored vehicle, the same material can be used as is already used for armoring the vehicle.
- a preferred embodiment also provides for the perforated plates to be fitted into an installation frame.
- the mounting frame with the perforated plates is then fitted into the opening.
- the perforated plates themselves can be layered by means of receiving means.
- corresponding bores are provided at the corners of the perforated plates in order to mount the plates in layers one on top of the other by means of receiving means.
- the receiving means can also be attached to the installation frame.
- the receiving means consist of bolts. To fasten the perforated plates, they can be locked on the receiving means, for example by means of nuts.
- the holes in the perforated plates are to be understood as continuous recesses, the shape of the holes not initially being defined.
- the perforated plates are designed with round holes, since these can be simply designed as a bore in terms of production technology.
- the perforated plates are preferably arranged parallel to one another, which ensures uniform, continuous protection within the entire opening.
- the holes can also be arranged offset to one another or at an angle to one another. Depending on the protection requirement, if z. If a very large opening is used, areas under the opening may require more protection than others.
- the plates can thus be arranged with different thicknesses relative to one another in order to make the protection that the plates ensure for the opening different in location.
- at least one plate could be designed to be wave-shaped on at least one surface. This design favors the property of a splinter trap.
- the space with the device is preferably used in a vehicle, in particular an armored vehicle. But it is also possible to install the room in other objects in need of protection, for example buildings, containers or stationary, armored units.
- the perforated plates 1, 2, 3 have holes 4.
- the holes 4 are distributed regularly and evenly on the perforated plates 1, 2, 3 and ensure a sufficient air flow of the ventilation system, which connects the room with the device.
- the perforated plates consist of different degrees of hardness, the perforated plates 1, 3 having a higher hardness than the perforated plate 2.
- This sandwich-like structure ensures that, in the event of ballistic effects, splinters get caught between and / or in the individual perforated plates 1, 2, 3 and do not get into the ventilation system or the room.
- the soft material of the perforated plate 2 ensures that splinters deform the soft material and thus the energy of the splinters can be absorbed before it can act on the ventilation system or the room.
- the installation frame 6 in which the perforated plates 1, 2, 3 are arranged is fitted into the opening by simple assembly means. This can be done by screwing, welding, soldering or locking.
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Entlüften oder Belüften eines Raumes, wobei der Raum durch Wände begrenzt ist, wie zum Beispiel in
Solche Vorrichtungen werden zur Luftzuführung in, bzw. -abführung aus einem Raum benötigt, wenn der Raum einen Luftaustausch mit der angrenzenden Umgebung benötigt. Dieses ist beispielsweise in Fahrzeugen der Fall, zur Belüftung der Innenräume der Fahrzeuge sowie auch zur Abführung und Zuführung der Luft einer Klimaanlage. Andere Anwendungsbeispiele sind Be- und Entlüftung von stationären Räumen, wie beispielsweise Häusern oder Containern.Such devices are required for supplying air into or out of a room when the room needs an exchange of air with the surrounding environment. This is the case, for example, in vehicles, for ventilating the interiors of the vehicles and also for removing and supplying the air to an air conditioning system. Other application examples are ventilation of stationary rooms, such as houses or containers.
Die erfindungsgemäße Vorrichtung soll einen Luftfluss zur Be- und Entlüftung des Raumes ermöglichen und somit der Belüftung bzw. Entlüftung einen möglichst geringen Widerstand entgegensetzen. Dazu wird eine Öffnung in mindestens einem der Wände benötigt. Die Vorrichtung deckt dann diese Öffnung bei gleichzeitiger Ermöglichung des Luftflusses ab. Die Vorrichtung soll jedoch robust und stabil gestaltet sein, sodass die Luftführung möglichst durch äußere Einwirkung nicht beeinträchtigt wird.The device according to the invention is intended to enable an air flow for ventilating and ventilating the room and thus oppose the least possible resistance to ventilation or venting. This requires an opening in at least one of the walls. The device then covers this opening while at the same time allowing air to flow. However, the device should be designed to be robust and stable, so that the air flow is not impaired by external influences as far as possible.
Eine entsprechende Vorrichtung ist aus dem Stand der Technik bekannt, beispielsweise aus der
Durch die relativ großen Öffnungen eines Grätings ist jedoch ein Schutz gegen ballistische äußere Einwirkungen, wie beispielsweise durch Projektile, nur schwer möglich.However, due to the relatively large openings in a grating, protection against external ballistic effects, such as projectiles, is difficult.
Aufgabe der vorliegenden Erfindung ist es somit, eine Vorrichtung zum Entlüften und Belüften eines Raumes bereitzustellen, wobei die Vorrichtung so gestaltet ist, dass die Be- und Entlüftung möglichst gut gegen äußere Einwirkungen geschützt ist, auch durch ballistische Einwirkung und trotzdem einen hohen Luftfluss ermöglicht.The object of the present invention is therefore to provide a device for venting and ventilating a room, the device being designed so that the ventilation is protected as well as possible against external influences, including ballistic effects, and nevertheless enables a high air flow.
Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst, nämlich durch eine Vorrichtung zum Entlüften oder Belüften eines Raumes, wobei der Raum durch Wände begrenzt ist, mit einer Lüftungsanlage zur Erzeugung eines Luftflusses und einer Öffnung in mindestens einer der Wände, an welcher der Luftfluss beginnt oder endet. Erfindungsgemäß ist die Vorrichtung zur Abdeckung der Öffnung geeignet, und aus mindestens drei Lochplatten besteht, wobei die Lochplatten schichtweise aneinander angeordnet sind und zwei unterschiedliche Härten aufweisen.This object is achieved by the features of the main claim, namely by a device for venting or ventilating a room, the room being delimited by walls, with a ventilation system for generating an air flow and an opening in at least one of the walls at which the air flow begins or ends. According to the invention, the device is suitable for covering the opening and consists of at least three perforated plates, the perforated plates being arranged in layers on one another and having two different hardnesses.
Der Raum, der durch die efindungsgemäße Vorrichtung entlüftet oder belüftet werden soll, ist durch Wände begrenzt und somit in sich geschlossen. Um nun einen Luftaustausch zu ermögliche, ist eine Öffnung in mindestens einer der Wände vorgesehen, an weicher der Luftfluss beginnt oder endet. Ebenso ist eine Lüftungsanlage zur Erzeugung eines Luftflusses vorgesehen.The space that is to be vented or ventilated by the device according to the invention is delimited by walls and is therefore self-contained. In order to enable an exchange of air, an opening is provided in at least one of the walls, at which the air flow begins or ends. A ventilation system for generating an air flow is also provided.
Eine solche Lüftungsanlage kann im einfachsten Falle ein Rohr oder Schlauch sein, der den Innenraum mit der Öffnung im Raum verbindet. Durch Temperaturunterschiede im Inneren des Raumes gegenüber außerhalb des Raumes oder auch durch unterschiedliche Luftzusammensetzungen, beispielsweise unterschiedlicher Sauerstoffkonzentration, wird dann der Luftfluss ermöglicht. Er führt vom Inneren des Raumes durch das Rohr oder den Schlauch zur Öffnung hin. Die Luftflussrichtung kann hierbei von der Öffnung in den Raum hinein oder anders herum sein.In the simplest case, such a ventilation system can be a pipe or hose that connects the interior with the opening in the room. The air flow is then made possible by temperature differences inside the room compared to outside the room or also by different air compositions, for example different oxygen concentrations. It leads from the inside of the room through the pipe or hose to the opening. The air flow direction can be from the opening into the room or the other way around.
Bevorzugterweise ist mindestens ein Ventilator oder eine ähnliche Strömungsmaschine vorgesehen, welche eine Luftumwälzung generiert und somit den Luftfluss steuert oder verstärkt. Ebenso kann als Lüftungsanlage eine Klimaanlage verwendet werden.At least one fan or a similar flow machine is preferably provided, which generates an air circulation and thus controls or amplifies the air flow. An air conditioning system can also be used as the ventilation system.
Durch die Lüftungsanlage entsteht nun ein Luftfluss hin zur Öffnung oder weg von der Öffnung und durch die Öffnung ist somit der geschlossene Raum an Stelle der Öffnung durchbrochen. Um diesen Durchbruch zu schützen wird die Öffnung erfindungsgemäß durch mindestens drei Lochplatten abgedeckt. Die Lochplatten sind schichtweise aneinander angeordnet und weisen zwei unterschiedliche Härten auf. Die Abdeckung ist damit derart gestaltet, dass die Vorrichtung begehbar gestaltet ist, wenn beispielsweise die Öffnung am Dach des Raumes angeordnet ist und gegen ballistische Einwirkung geschützt ist. Dieser Schutz gegen ballistische Einwirkungen wird dadurch erzielt, dass zum einen die Lochplatten mit der höheren Härte dafür sorgen, dass ballistische Einwirkungen gar nicht erst in die Öffnung eintreten und die Lochplatte mit der niedrigeren Härte dafür sorgt, dass die Energieeinwirkung durch die ballistische Einwirkung auf die Vorrichtung kompensiert wird. Dies wird, unter anderem, dadurch erreicht, dass die Lochplatte mit der niedrigeren Härte durch eine solche Einwirkung verformt wird und somit die Energie aufnimmt.The ventilation system now creates an air flow towards the opening or away from the opening and the closed space is broken through the opening instead of the opening. In order to protect this breakthrough, the opening is covered according to the invention by at least three perforated plates. The perforated plates are arranged in layers next to one another and have two different degrees of hardness. The cover is thus designed in such a way that the device is designed to be accessible if, for example, the opening is arranged on the roof of the room and is protected against ballistic impact. This protection against ballistic effects is achieved in that, on the one hand, the perforated plates with the higher hardness ensure that ballistic effects do not even enter the opening and the perforated plate with the lower hardness ensures that the energy effect through the ballistic effect on the Device is compensated. This is achieved, among other things, in that the perforated plate with the lower hardness is deformed by such an action and thus absorbs the energy.
Die mindestens drei Lagen sorgen durch ihre schichtweise Anordnung dafür, dass in den Zwischenräumen bzw. Löchern Splitter und andere Materialabscherungen aufgefangen werden und nicht in den Raum hineingelangen können.The layered arrangement of the at least three layers ensures that splinters and other material sheared off are caught in the spaces or holes and cannot get into the room.
Die Löcher der Lochplatten können je nach Anforderung gestaltet werden. So können größere Löcher verwendet werden, um einen größeren Luftdurchfluss zu gewährleisten. Je größer die Löcher sind, desto geringer ist jedoch der Schutz, den die Vorrichtung vor äußeren Einwirkungen bietet. So kann durch Variation der Lochgröße bzw. der Lochüberschneidung, je nach Anforderung, zwischen größtmöglichem Luftdurchfluss und größtmöglichem Schutz variiert werden.The holes in the perforated plates can be designed as required. This allows larger holes to be used to allow greater air flow. However, the larger the holes, the less the protection that the device offers from external influences. By varying the hole size or the hole overlap, depending on the requirements, it is possible to vary between the greatest possible air flow and the greatest possible protection.
Die Lochplatten bestehen erfindungsgemäß aus zwei unterschiedlichen Härten, wobei die nach außen gerichtete Lochplatte eine hohe Härte aufweisen sollte. Dies dient der Realisierung der Begehbarkeit der vorliegenden Vorrichtung und sorgt dafür, dass möglichst ein hoher Schutz des Raumes besteht. Die Verwendung eines Materials mit einer höheren Härte sorgt dafür, dass die Öffnung sicher abgedeckt ist und somit der Raum weitestgehend von den Wänden und der Vorrichtung vollständig begrenzt ist.According to the invention, the perforated plates consist of two different hardnesses, the outwardly directed perforated plate should have a high level of hardness. This is used to make the present device accessible and ensures that the room is protected as much as possible. The use of a material with a higher hardness ensures that the opening is securely covered and thus the space is largely completely limited by the walls and the device.
Bevorzugterweise verlaufen die Löcher in den Lochplatten senkrecht, d. h. sie verlaufen senkrecht zur Ebene der Platte. Dieser senkrechte Lochverlauf begünstigt einen möglichst kurzen Luftflussweg durch die Lochplatte und somit einen möglichst geringen Widerstand. Die Löcher der Lochplatte können aber auch schräg zur Ebene der Lochplatte angeordnet sein, um einen größeren Schutz gegen äußere Einwirkungen zu gewährleisten. Hierbei ist es dann auch möglich, dass die Bohrungen in den unterschiedlichen Lochplatten in unterschiedlichen Schräglagen vorgesehen sind, oder die Schrägen der Löcher entgegengesetzt zueinander sind, sodass eine erste Lochplatte Löcher mit einer bestimmten Schräge aufweist und die danach folgende Lochplatte also die darunterliegenden oder darüber liegenden Löcher in einem entgegengesetzten Winkel zur ersten Lochplatte aufweist. Diese Maßnahmen begünstigen ebenfalls einen Schutz gegen äußere Einwirkungen, insbesondere ballistische Einwirkungen auf die Vorrichtung.The holes in the perforated plates preferably run vertically, ie they run perpendicular to the plane of the plate. This perpendicular course of the hole favors the shortest possible air flow path through the perforated plate and thus the lowest possible resistance. The holes in the perforated plate can, however, also be arranged at an angle to the plane of the perforated plate in order to ensure greater protection against external influences. It is then also possible that the bores in the different perforated plates are provided in different inclined positions, or the inclines of the holes are opposite to one another, so that a first perforated plate has holes with a certain incline and the perforated plate that follows the perforated plate below or above it Has holes at an opposite angle to the first perforated plate. These measures also benefit one Protection against external influences, in particular ballistic effects on the device.
Durch die schräge Anordnung der Löcher ist es auch möglich, die einzelnen Lochplatten dünner zu gestalten als bei senkrecht verlaufenden Löchern, da der Weg durch die Lochplatte bei einem schräg angeordneten Loch bereits länger ist als durch ein senkrecht angeordnetes Loch. Die Schutzfunktion der Lochplatte kann also durch die Dicke und/oder durch die Anordnung der Löcher in der Lochplatte gewährleistet werden.Due to the inclined arrangement of the holes, it is also possible to make the individual perforated plates thinner than in the case of perpendicular holes, since the path through the perforated plate is already longer with an obliquely arranged hole than through a vertically arranged hole. The protective function of the perforated plate can therefore be ensured through the thickness and / or through the arrangement of the holes in the perforated plate.
In einer besonderen Ausführungsform sind die Lochplatten mit der höheren Härte aus Panzerstahl gefertigt. Dies hat den Vorteil, dass bei Einbringung der Vorrichtung in ein gepanzertes Fahrzeug, das gleiche Material verwendet werden kann, wie es zur Panzerung des Fahrzeugs bereits verwendet wird.In a special embodiment, the perforated plates with the higher hardness are made of armored steel. This has the advantage that when the device is introduced into an armored vehicle, the same material can be used as is already used for armoring the vehicle.
Ebenso ist in einer bevorzugten Ausführungsform die Lochplatte mit der niedrigeren Härte aus Aluminium gefertigt. Der Werkstoff Aluminium begünstigt eine Verformung der Lochplatte bzw. der Löcher bei Einwirkung auf die Lochplatte, sodass Energie aufgenommen werden kann und somit der Raum entsprechend geschützt ist.Likewise, in a preferred embodiment, the perforated plate with the lower hardness is made of aluminum. The material aluminum favors a deformation of the perforated plate or the holes when acting on the perforated plate, so that energy can be absorbed and the room is protected accordingly.
Zur Vereinfachung der Montage ist weiterhin in einer bevorzugten Ausführungsform vorgesehen, dass die Lochplatten in einen Einbaurahmen eingepasst sind. Der Einbaurahmen mit den Lochplatten wird dann in die Öffnung eingepasst. Die Lochplatten selber können mittels Aufnahmemittel geschichtet werden. Dazu wird bevorzugterweise vorgeschlagen, dass an den Ecken der Lochplatten entsprechende Bohrungen vorgesehen sind, um mittels Aufnahmemittel die Platten aufeinander geschichtet zu montieren. In der Ausführungsform mit dem Einbaurahmen können die Aufnahmemittel auch an dem Einbaurahmen angebracht werden. In der einfachsten Ausführungsform bestehen die Aufnahmemittel aus Bolzen. Zur Befestigung der Lochplatten können diese auf den Aufnahmemitteln arretiert werden, beispielsweise mittels Muttern.To simplify assembly, a preferred embodiment also provides for the perforated plates to be fitted into an installation frame. The mounting frame with the perforated plates is then fitted into the opening. The perforated plates themselves can be layered by means of receiving means. For this purpose, it is preferably proposed that corresponding bores are provided at the corners of the perforated plates in order to mount the plates in layers one on top of the other by means of receiving means. In the embodiment with the installation frame, the receiving means can also be attached to the installation frame. In the simplest embodiment, the receiving means consist of bolts. To fasten the perforated plates, they can be locked on the receiving means, for example by means of nuts.
Die Löcher in den Lochplatten sind als durchgehende Ausnehmungen zu verstehen, wobei die Form der Löcher zunächst nicht festgelegt ist. Bevorzugterweise wird jedoch vorgeschlagen, dass die Lochplatten mit runden Löchern ausgestaltet sind, da diese fertigungstechnisch einfach als Bohrung ausgeführt werden können. Ebenso ist es jedoch auch möglich, die Löcher mehreckig zu gestalten. Dies kann beispielsweise durch Stanzen der Lochplatten geschehen.The holes in the perforated plates are to be understood as continuous recesses, the shape of the holes not initially being defined. However, it is preferably proposed that the perforated plates are designed with round holes, since these can be simply designed as a bore in terms of production technology. However, it is also possible to make the holes polygonal. This can be done, for example, by punching the perforated plates.
Die Lochplatten sind bevorzugterweise parallel zueinander angeordnet, was einen gleichmäßigen durchgehenden Schutz innerhalb der gesamten Öffnung gewährleistet. Die Löcher können aber auch versetzt zueinander oder schräg zueinander angeordnet sein. Je nach Schutzanforderung, wenn z. B eine sehr große Öffnung verwendet wird, können Bereiche unter der Öffnung größeren Schutz bedürfen als andere. Somit können die Platten mit unterschiedlichen Dicken zueinander angeordnet sein, um den Schutz, den die Platten für die Öffnung gewährleisten, örtlich unterschiedlich zu gestalten. Außerdem könnte mindestens eine Platte wellenförmig auf mindestens einer Oberfläche gestaltet sein. Diese Bauform begünstigt die Eigenschaft eines Splitterfanges.The perforated plates are preferably arranged parallel to one another, which ensures uniform, continuous protection within the entire opening. However, the holes can also be arranged offset to one another or at an angle to one another. Depending on the protection requirement, if z. If a very large opening is used, areas under the opening may require more protection than others. The plates can thus be arranged with different thicknesses relative to one another in order to make the protection that the plates ensure for the opening different in location. In addition, at least one plate could be designed to be wave-shaped on at least one surface. This design favors the property of a splinter trap.
Bevorzugterweise wird der Raum mit der Vorrichtung in einem Fahrzeug, insbesondere einem gepanzerten Fahrzeug verwendet. Es ist aber ebenso möglich, den Raum in anderen schutzbedürftigen Objekten einzubauen, beispielsweise Gebäude, Container oder stationäre, gepanzerte Einheiten.The space with the device is preferably used in a vehicle, in particular an armored vehicle. But it is also possible to install the room in other objects in need of protection, for example buildings, containers or stationary, armored units.

- a perspective structure of the device according to the invention.
Die Lochplatten 1, 2, 3 weisen Löcher 4 auf. In
Die Löcher 4 können schräg angeordnet sein oder wie im vorliegenden Figurenbeispiel senkrecht. Durch diese Anordnungsmöglichkeit sowie den Überschneidungen der Löcher 4 zueinander kann der mögliche Luftfluss geregelt werden. Ebenso wird durch diese Anordnung der Schutz beeinflusst, welcher sich durch die Vorrichtung für die Öffnung ergibt. Die Vorrichtung schützt die Öffnung vor äußeren Einwirkungen, insbesondere ballistischer Einwirkung.The
Zum Erreichen dieser Schutzwirkung bestehen die Lochplatten aus unterschiedlich Härten, wobei die Lochplatten 1, 3 die höhere Härte gegenüber der Lochplatte 2 aufweisen.To achieve this protective effect, the perforated plates consist of different degrees of hardness, the
Durch diesen sandwichartigen Aufbau wird erreicht, dass bei ballistischen Einwirkungen sich zum einen Splitter zwischen und/oder in den einzelnen Lochplatten 1, 2 3 verfangen und nicht in die Lüftungsanlage bzw. den Raum gelangen. Zum anderen sorgt das weiche Material der Lochplatte 2 dafür, dass Splitter das weiche Material verformen und somit die Energie der Splitter aufgenommen werden kann, bevor sie auf die Lüftungsanlage oder den Raum einwirken kann.This sandwich-like structure ensures that, in the event of ballistic effects, splinters get caught between and / or in the individual
Der Einbaurahmen 6 in welchem die Lochplatten 1, 2, 3 angeordnet sind, wird durch einfache Montagemittel in die Öffnung eingepasst. Dies kann durch Verschraubungen, Verschweißen, Verlöten oder Einrasten geschehen.The
Die vorliegende Erfindung ist nicht auf die oben genannten Merkmale begrenzt, vielmehr sind weitere Ausgestaltungen denkbar. So können die Lochplatten statt rechteckig auch jede andere Form annehmen, beispielsweise rund oder oval. Dadurch kann die Vorrichtung auf die entsprechende zu schützende Öffnung eingepasst werden. Ebenso sind auch weitere Materialien für die Lochplatten denkbar, wie beispielsweise Edelstahl und Kunststoff. Wichtig hierbei ist lediglich, dass die Platten mit den höheren Härten dazu geeignet sind, äußeren Einwirkungen zu widerstehen, weshalb sich harte Metalle als wirkungsvoll erwiesen haben. Dahingegen muss die Platte mit der niedrigeren Härte dazu geeignet sein, Energie aufnehmen zu können, beispielsweise durch Verformung. Dazu können Aluminium, Kunststoffe aber auch Gummi oder Hartpapier verwendet werden.The present invention is not limited to the features mentioned above; rather, further refinements are conceivable. Instead of rectangular, the perforated plates can also assume any other shape, for example round or oval. As a result, the device can be fitted onto the corresponding opening to be protected. Other materials, such as stainless steel and plastic, are also conceivable for the perforated plates. The only important thing here is that the plates with the higher hardness are suitable to withstand external influences, which is why hard metals have proven to be effective. In contrast, the plate with the lower hardness must be suitable for absorbing energy, for example by deformation. Aluminum, plastics, but also rubber or hard paper can be used for this.
