Description

Die Erfindung bezieht sich auf einen Evakuierungsschlauch als Transportmittel nach dem Oberbegriff des Anspruchs 1.The invention relates to an evacuation hose as a means of transport according to the preamble of claim 1.

Ein gattungsgleicher Evakuierungsschlauch ist aus der GB-A-1 502 188 bekannt. Der Schlauch ist doppelwandig ausgeführt. Der durch die Doppelwand gebildete Zwischenraum ist oben und unten verschlossen, so dass eine geschlossene Kammer entsteht. Die Kammer ist ausdehnbar, weil sowohl der Innenschlauch als auch der Außenschlauch biegsam sind. Zur Einstellung des Innendurchmessers wird die ausdehnbare Kammer in Abhängigkeit von pneumatischen Detektoren und einem Rechner mit Druckluft beaufschlag. Der Druck in der Kammer ist einstellbar um Körper mit stark unterschiedlicher Dicke evakuieren zu können. Der apparative Aufwand ist relativ groß, wobei nicht überall elektrische Energie zur Verfügung steht.A generic evacuation tube is known from GB-A-1 502 188. The hose is double-walled. The gap formed by the double wall is closed at the top and bottom, so that a closed chamber is formed. The chamber is expandable because both the inner tube and the outer tube are flexible. To adjust the inner diameter, the expandable chamber is acted upon by compressed air, depending on pneumatic detectors and a computer. The pressure in the chamber is adjustable to evacuate bodies of widely varying thickness. The equipment is relatively large, with not everywhere electrical energy is available.

Aus der DE 199 17 188 ist ein Rettungsgerät für Personen aus Schiffen bekannt. Dieses Rettungsgerät ist als Rutsche in Form eines aufblasbaren Schlauches ausgebildet. Der Schlauch ist aufgrund einer Innenwand und einer Außenwand doppelwandig und aufblasbar. Die beiden Enden des Schlauches sind zum einen mit dem Schiff und zum anderen mit einem Rettungsboot fest verbunden. Eine derartige Rutsche eignet sich zwar für den Einsatz an einem Ort, bei dem der Anfangs- und Endpunkt immer denselben Abstand aufweisen, jedoch weniger bei sich distanzmäßig verändernden End- und Anfangspunkten, wie beispielsweise bei einem zu evakuierenden Schiff. Bei großem Wellengang würde das Rettungsboot - parallel zur Bewegung des Schiffes - hin- und hergeschoben bzw. gezogen. Wenn ein Schiff evakuiert werden soll, wobei der Einstiegspunkt für Personen in den Schlauch in ca. 10 Meter Höhe über dem Wasser liegt, würde bei einem Kränkungswinkel des Schiffes von 20° die Differenzhöhe etwa 0,6 Meter betragen und die Abweichung vom Lot etwa 3,4 Meter. Nachdem der Schlauch in sich stabil ist, also eine nur geringe Durchbiegung aufweist, verändern sich die Rutschbedingungen aufgrund der minimalen und maximalen Schräge des Schlauches. Insbesondere bei einer maximalen Schräge des Schlauches ist die maximale Rutschgeschwindigkeit einer Person zu hoch, so dass am Ende des Schlauches aufwendige Bremssysteme erforderlich sind, um eine Verletzung der zu rettenden Person beim Aufprall im Rettungsboot zu vermeiden.From DE 199 17 188 a rescue device for persons from ships is known. This rescue device is designed as a slide in the form of an inflatable tube. The hose is double-walled and inflatable due to an inner wall and an outer wall. The two ends of the hose are firmly connected to the ship and to another with a lifeboat. Although such a slide is suitable for use in a location where the start and end points always have the same distance, but less at distantly varying end and start points, such as in a ship to be evacuated. In case of a large swell, the lifeboat would be pushed or pulled parallel to the movement of the ship. If a ship is to be evacuated, with the entry point for persons into the hose being about 10 meters above the water, the difference height would be about 0.6 meters and the deviation from the solder about 3 with an angle of elevation of the ship of 20 ° 4 meters. After the hose is stable in itself, that is, has only a slight deflection, the sliding conditions change due to the minimum and maximum slope of the hose. In particular, with a maximum slope of the hose, the maximum sliding speed of a person is too high, so that at the end of the hose consuming braking systems are required to avoid injury to the person to be rescued during the impact in the lifeboat.

Aufgabe der Erfindung ist es, einen Schlauch vorzuschlagen der ein bezüglich der Geschwindigkeit kontrolliertes Rutschen ermöglicht. Außerdem soll bei Veränderungen des Ausgangspunktes und/oder des Endpunktes die Rutschbedingungen gleichbleiben.The object of the invention is to propose a hose which allows controlled in terms of speed slipping. In addition, should change the starting point and / or the end point, the sliding conditions remain the same.

Die Erfindung löst diese Aufgabe entsprechend den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.The invention solves this problem according to the characterizing features of claim 1. Advantageous developments of the invention can be found in the dependent claims.

Vorteilhaft wird durch die Erfindung erreicht, daß Menschen, Tiere, Güter langsam rutschen und kontrolliert unten ankommen. Verletzungen oder Beschädigungen, insbesondere durch zu hohe Reibungswärme, werden vermieden.Advantageously, it is achieved by the invention that humans, animals, goods slip slowly and arrive controlled below. Injuries or damage, especially due to excessive frictional heat, are avoided.

Der Schlauch ist kostengünstig. Er benötigt keine Kontrollinstrumente oder Steuerungen. In einfacher Weise ist er vom Ausgangsort aus, beispielsweise einem Schiff, mit dem Endpunkt zu verbinden. Anschließend ist der ringförmige Kammerbereich des Schlauches wenigstens soweit aufzupumpen, daß er dem atmosphärischen Druck entspricht. Ein Nachfüllen des ringförmigen Kammerbereiches ist nach dem Durchrutschen, beispielsweise einer Person nicht erforderlich.
Andererseits ist der Schlauch an den sogenannten Rutschdurchmesser einer zu befördernden Person oder eines Gegenstandes anpaßbar, indem bei einem Erwachsenen der Druck im Ringkammerbereich erniedrigt, jedoch bei einem Kind der Druck erhöht wird. Tiere und Güter sind in einfacher Weise in einer speziellen, angepaßten Kabine oder Behälter zu befördern.
The hose is inexpensive. He needs no control instruments or controls. In a simple way, he is from the starting point, such as a ship to connect to the end point. Subsequently, the annular chamber portion of the tube is at least pump up to the extent that it corresponds to the atmospheric pressure. Refilling the annular chamber area is not required after slipping, for example a person.
On the other hand, the hose is adaptable to the so-called slip diameter of a person or object to be conveyed by lowering the pressure in the annular chamber area in an adult, but increasing pressure in a child. Animals and goods are easily transported in a special, adapted cabin or container.

Der Einstieg des Schlauches ist zum Beispiel am offenen Deck eines Schiffes befestigt. Er hat den vollen, also maximalen Querschnitt. Über einen Trichter wird die zu rettende Person in den inneren, dehnfähigen Schlauch geführt, dessen Wände beispielsweise Gummizüge aufweisen. Zwischen Innen- und Außenschlauch sind waagerechte Trennwände angeordnet, die den Ringraum in einzelne Kammern unterteilen. Die Trennwände weisen Drosseln auf, die bei Überdruck öffnen, bzw. für einen Druckausgleich zwischen den Ringkammern sorgen.The entry of the hose is attached to the open deck of a ship, for example. He has the full, so maximum cross-section. About a funnel the person to be rescued is guided in the inner, stretchable hose whose walls have, for example, rubber bands. Between inner and outer tube horizontal partitions are arranged, which divide the annulus into individual chambers. The partitions have throttles, which open at overpressure, or ensure a pressure equalization between the annular chambers.

Wenn sich ein Mensch durch diesen Doppelschlauch bewegt, muß er den Innenschlauch aufweiten. Dabei gibt es zwei Effekte:

  1. 1. Zwischen dem Menschen und der Wand des Innenschlauches tritt eine Reibungskraft auf, deren vertikale Komponente seine Fallgeschwindigkeit abbremst.
  2. 2. Wesentlicher, weil wirkungsvolle ist der zweite Effekt. Die Innenwand des Innenschlauches wird aufgeweitet und gegen die feste Außenwand gedrückt, da die waagerechten Kammerwände Drosseln aufweisen, erfolgt ein Druckausgleich im Ringraum. Damit kann der Innenschlauch aufgeweitet werden. Ohne die Möglichkeit der Luft durch Ventile zu entweichen, würde der Durchmesser des Innenschlauches für den Menschen zu klein sein; der Mensch würde am Ende des Einstiegstrichters liegen bleiben, da die Vertikalkomponente der von der Wand auf ihn ausgeübten Haltekraft eine Abwärtsbewegung verhindern würde.
If a person moves through this double tube, he must widen the inner tube. There are two effects:
  1. 1. Between the human and the wall of the inner tube occurs a frictional force whose vertical component slows down its falling speed.
  2. 2. More important, because effective is the second effect. The inner wall of the inner tube is widened and pressed against the fixed outer wall, since the horizontal chamber walls have throttles, a pressure equalization takes place in the annular space. This allows the inner tube to be widened. Without the possibility of air venting through valves, the diameter of the inner tube would be too small for humans; the human would remain lying at the end of the manhole, as the vertical component of the holding force applied to it by the wall would prevent downward movement.

Über die Größe und Anzahl der Ventile kann leicht die Größe der Haltekraft, d. h. die Geschwindigkeit des Menschen gesteuert werden.About the size and number of valves can easily the size of the holding force, d. H. the speed of man are controlled.

Die Gummizüge sorgen dafür, daß der Durchmesser des Innenschlauches immer seinen minimalen Durchmesser annimmt, also zum einen eng an der vorbeigleitenden Person anliegt und zum anderen sofort wieder den Ausgangszustand herstellt. Dabei werden die Kammern durch das Einströmen der Luft durch die Ventile wieder gefüllt.The elastic bands ensure that the diameter of the inner tube always assumes its minimum diameter, so for a tight fit against the passing person and on the other hand immediately restores the initial state. The chambers are filled by the influx of air through the valves again.

Wesentlich ist auch, daß der vorbeschriebene Mechanismus kein schwingungsfähiges System darstellt. Die überwiegende Energie des fallenden Menschen wird durch Drosselverluste, durch Verwirbelung der Luft vernichtet.It is also essential that the above-described mechanism is not a vibratory system. The overwhelming energy of the falling man is destroyed by throttling losses, by turbulence of the air.

Ein Evakuierungsschlauch 1 besteht aus einem dehnbaren Innenschlauch 2, einem festen Außenschlauch 3, einem Einstiegstrichter 4 und aus einem Ringbereich 5.An evacuation hose 1 consists of an expandable inner tube 2, a fixed outer tube 3, an entry funnel 4 and a ring area 5.

Der Ringbereich 5 ist durch Trennwände 6 in axial untereinander liegende Ringkammern 7 bis 11 geteilt. Drosseln in Form von Schlitzventilen 12 (Fig. 2) sind in den Wänden 6 integriert.The annular region 5 is divided by partitions 6 in axially underlying ring chambers 7 to 11. Throttles in the form of slit valves 12 (FIG. 2) are integrated in the walls 6.

Die Wände 12 liegen in einem axialen Abstand 13, der etwa der Hälfte der Länge 14 des Rumpfes 15 eines schematisch dargestellten Menschen 16 entspricht.The walls 12 are at an axial distance 13, which corresponds to about half of the length 14 of the fuselage 15 of a schematically illustrated human 16.

Der Durchmesser 20 des Innenschlauches 2 ist wesentlich kleiner als der mittlere Durchmesser 21 des Menschen 16.The diameter 20 of the inner tube 2 is substantially smaller than the average diameter 21 of the human 16.

Ein strichpunktiert gezeichneter, seitlicher Einstiegstrichter im Evakuierungsschlauch 1 ist mit 24 bezeichnet.A dot-dash line, side entry funnel in the evacuation tube 1 is designated 24.

Gummizüge 25 sorgen dafür, daß der Durchmesser 20 des Innenschlauches 2 immer seinen minimalen Durchmesser annimmt.Elastic bands 25 ensure that the diameter 20 of the inner tube 2 always assumes its minimum diameter.

Zur Funktion:To the function:

Der an Schlaufen 26, 27 zu befestigende Evakuierungsschlauch 1 überbrückt die Distanz zwischen einem zu evakuierenden Schiff und einem Rettungsboot (nicht dargestellt). Ein zu evakuierender Mensch 16 steigt in den Einstiegstrichter 4 und gleitet mit den Füßen voraus durch den Innenschlauch 2. Der Innenschlauch 2 wird im Bereich des Rumpfes 15 des Menschen 16 ausgedehnt. In dem Bereich der Ringkammern 9, 10 erfolgt dadurch eine Kompression der Luft, die durch die Schlitzventile 12 in die benachbarten Kammern 8, 11 gelangt. Beim weiteren Durchrutschen werden dann die Ringkammern 9, 10 entlastet, während die Ringkammer 11 komprimiert wird. Die entlasteten Ringkammern 9, 10 werden von der Ringkammer 8 und von der Ringkammer 11 soweit mit Luft versorgt, so daß der Innenschlauch 2 seinen ursprünglichen Durchmesser 20 wieder annimmt. Unterstützt wird dies durch die Gummizüge 25.The evacuation hose 1 to be attached to loops 26, 27 bridges the distance between a ship to be evacuated and a lifeboat (not shown). A person to be evacuated 16 rises into the entry funnel 4 and slides with his feet ahead through the inner tube 2. The inner tube 2 is extended in the region of the trunk 15 of the human 16. In the region of the annular chambers 9, 10 thereby takes place a compression of the air, which passes through the slit valves 12 in the adjacent chambers 8, 11. Upon further slipping then the annular chambers 9, 10 are relieved, while the annular chamber 11 is compressed. The relieved annular chambers 9, 10 are so far supplied with air from the annular chamber 8 and from the annular chamber 11, so that the inner tube 2 assumes its original diameter 20 again. This is supported by the elastic bands 25.

Bei einer weiteren Ausführungsform nach Fig. 3 sind die horizontalen Trennwände 6 geschlossen. Demgegenüber weist der Innenschlauch 2 Löcher 30 für den Luftaustritt auf. Die durchrutschende Person 16 weitet den Innenschlauch 2 auf und drückt den Innenschlauch 2 gegen die quasi formstabile Wand des Außenschlauches 3. Da die waagerechten Trennwände 6 eine Luftströmung mit Druckausgleich in dem Ringbereich 5 unterbinden, kann sich der Innenschlauch 2 aber nur aufweiten, wenn die überflüssige Luft durch die Löcher 30 des Innenschlauchs 2 in den Inneraum des Innenschlauches 2, d. h. ins Freie entweichen kann.
Über die Größe und Anzahl der Löcher 30 ist die Größe der Haltekraft, d. h., die Geschwindigkeit der Person 16 zu steuern. Die Gummizüge 25 des Innenschlauchs 2 sorgen dafür, daß er immer seinen minimalen Durchmesser annimmt, also zum einen eng an der vorbeigleitenden Person 16 anliegt und zum anderen sofort anschließend wieder den Ausgangszustand, wie gezeichnet, herstellt. Dabei werden die Ringkammern 7 bis 11 - durch das Einströmen der Luft durch die Schlitze 30 - wieder gefüllt.
In a further embodiment according to FIG. 3, the horizontal partitions 6 are closed. In contrast, the inner tube 2 holes 30 for the air outlet. The slipping person 16 expands the inner tube 2 and presses the inner tube 2 against the quasi-dimensionally stable wall of the outer tube 3. Since the horizontal partitions 6 prevent air flow with pressure compensation in the annular region 5, the inner tube 2 but can only widen if the superfluous Air through the holes 30 of the inner tube 2 in the interior of the inner tube 2, ie can escape to the outside.
About the size and number of holes 30 is the size of the holding force, that is, to control the speed of the person 16. The elastic bands 25 of the inner tube 2 ensure that it always assumes its minimum diameter, so on the one hand closely abuts the vorbeigleitenden person 16 and on the other hand immediately afterwards the initial state, as drawn, produces. The annular chambers 7 to 11 - filled by the influx of air through the slots 30 - again.

Große, frei zugängliche Luftausgleichslöcher können gefährlich sein, beispielsweise durch Verhaken von Schlössern, Schnallen, Fingern. Viele kleine Löcher mit einem Gitter abgedeckte Löcher sind teuer in der Herstellung und bieten einen sehr hohen Strömungwiederstand. Der hohe Strömungswiederstand ist unerwünscht beim Wiederfüllen der Ringkammer 7 - 11 nach dem Durchtritt der Person 16. Außerdem wird dadurch die Festigkeit des Innenschlauchs 2 deutlich gesenkt.Large, freely accessible air equalization holes can be dangerous, for example, by snagging locks, buckles, fingers. Many small holes covered with a grid are expensive to manufacture and provide very high flow resistance. The high flow resistance is undesirable when refilling the annular chamber 7 - 11 after the passage of the person 16. In addition, the strength of the inner tube 2 is thereby significantly reduced.

Verdeckte Löcher 30 im Innenschlauch 2 vermeiden nach Fig. 4 die vorgenannten Nachteile. Am Innenschlauch 2 sind Abdeckklappen 41 angeordnet. An den Abdeckklappen 41 greifen Gummizüge 42 an. Die Gummzüge 42 sind an den Abdeckklappen befestigt. Sobald die zu rettende Person 16 auf eine solche Abdeckklappe 41 trifft, verschließt sie diese. Das vorbeschriebene Verhaken oder Einfädeln ist nicht mehr möglich. Sobald die Person 16 die Abdeckklappe 41 passiert hat, wird sie durch die Gummizüge 42 wieder in die Position "Offen" ausgezogen, so daß wieder Luft in die Ringkammern 7 bis 11 zwischen Innen- und Außenschlauch 2, 3 strömen und diese füllen kann,Concealed holes 30 in the inner tube 2 avoid according to Fig. 4, the aforementioned disadvantages. At the inner tube 2 cover flaps 41 are arranged. At the cover flap 41 elastics 42 attack. The rubber cables 42 are attached to the cover flaps. As soon as the person to be rescued 16 encounters such a cover flap 41, it closes it. The above-mentioned hooking or threading is no longer possible. As soon as the person 16 has passed the cover flap 41, it is pulled out again by the elastics 42 into the "open" position, so that air can again flow into and fill the annular chambers 7 to 11 between the inner and outer tubes 2, 3.

Der maximale Öffnungwinkel der Abdeckklappen 41 wird durch Haltefäden 43, einen Lochstreifen (nicht gezeichnet) oder ähnliches festgelegt.The maximum opening angle of the cover flap 41 is determined by retaining threads 43, a perforated strip (not shown) or the like.

Anstelle der Halteklappen 41 kann die Haupt-Drosselwirkung auch mit einer Ringklappe 47 erreicht werden. Die Ringklappe 47 bildet mit dem Innenschlauch 2 einen Ringspalt 48. Sie ist bei 48 mit dem Innenschlauch 2 verbunden.Instead of the retaining flaps 41, the main throttle effect can also be achieved with a ring flap 47. The annular flap 47 forms with the inner tube 2 an annular gap 48. It is connected at 48 with the inner tube 2.

Eine Längenänderung ist bspw. aufgrund eine ziehharmonikaähnlichen Struktur des Außenschlauches 3 möglich. Die Längenänderung des Außenschlauches 3 beeinflußt auch eine entsprechende Änderung des Innenschlauches 2 der sich dem Außenschlauch anpaßt. Hierzu ist der Innenschlauch 2 nicht nur in Umfangsrichtung sondern auch in Längsrichtung elastisch. Letzeres kann über das Material erfolgen oder dadurch, daß man in einer Hauptachse 45 in geeigneten Abständen über den Umfang des Innenschlauches 2 nicht gezeichnete Gummifäden einzieht.A change in length is, for example, possible due to a concertina-like structure of the outer tube 3. The change in length of the outer tube 3 also affects a corresponding change of the inner tube 2 which adapts to the outer tube. For this purpose, the inner tube 2 is elastic not only in the circumferential direction but also in the longitudinal direction. The latter can take place via the material or by pulling in a main axis 45 at suitable intervals over the circumference of the inner tube 2 not drawn rubber threads.

Die vorbeschriebenen Aufbauten sind keine schwingungsfähige Systeme. Es gibt also keine Resonanz. Eine derartige Resonanz könnte den freien Querschnitt des Evakuierungsschlauches blockieren. Die Energie der fallenden Person 16 wird durch Verwirbelung der Luft in den Schlitzventilen 12 bzw. Löchern 30, 40 vernichtet.The above-described structures are not oscillatory systems. So there is no resonance. Such a resonance could block the free cross section of the evacuation tube. The energy of the falling person 16 is destroyed by turbulence of the air in the slit valves 12 and holes 30, 40.

Modifikationen bei dem Evakuierungsschlauch 1 sind ohne weiteres möglich. Beispielsweise kann ein spezieller Belag an der Innenwand, also der personenseitigen Wand des Innenschlauchs 2 angebracht sein, der einen weitgehend feuchtigkeitsunabhängigen Reibwert zwischen Innenwand 2 und Person 16 garantiert. Ein derartiger Belag kann an jeder geeigneten Stelle des Innenschlauchs 2 angebracht sein. Besonders vorteilhaft ist es, den vorgenannten Belag in einem Endabschnitt des Innenschlauchs 2 anzuordnen.Modifications to the evacuation hose 1 are readily possible. For example, a special coating on the inner wall, so the person-side wall of the inner tube 2 may be attached, which guarantees a largely moisture-independent coefficient of friction between the inner wall 2 and person 16. Such a coating may be attached to any suitable location of the inner tube 2. It is particularly advantageous to arrange the aforementioned lining in an end section of the inner tube 2.

Weiterhin kann hinsichtlich Längenausgleichseigenschaften und Kosten eine Kombination eines modifizierten, konventionellen mit dem hier vorgeschlagenen Evakuierungsschlauch 1 sein. Der gesamte Evakuierungsschlauch wird unterteilt in einen oberen und einen unteren Teil; einem einfach aufgebauten, in Längsrichtung elastischen Teil ohne Innenschlauch, das den Längenausgleich bringt und einen Teil, das die Fallenergie vernichtet.Furthermore, in terms of length compensation properties and cost may be a combination of a modified, conventional evacuation tube 1 with the proposed here. The entire evacuation tube is divided into an upper and a lower part; a simply constructed, longitudinally elastic part without inner tube that brings the length compensation and a part that destroys the energy trap.

Claims (1)

  1. Evacuation tube (1) as means of transportation for people, animals or items, comprising two tubes (2, 3) arranged one inside the other and connected to one another, the ringed area (5) of which is filled with air,
