Auftriebshilfe für WasserfahrzeugeBuoyancy aid for watercraft
Die Erfindung bezieht sich auf eine Auftriebshilfe für Wasserfahrzeuge in Seenot mit wenigstens einem Schwimmsack nach dem Oberbegriff des Anspruchs 1.The invention relates to a buoyancy aid for watercraft in distress with at least one swimming bag according to the preamble of claim 1.
Aus der EP-Bl 0 919 460 der Anmelderin ist eine Auftriebshilfe für Wasserfahrzeuge in Seenot mit wenigstens einem Schwimmsack bekannt. Im Inneren des Wasserfahrzeuges sind Schwimmsäcke angeordnet, die jeweils durch eine Gasquelle aufblasbar sind. Die Schwimmsäcke sind mit dem Wasserfahrzeug durch eine Fesselung verbunden. Die setzt voraus, dass jeder Schwimmsack separat mit einer externen Gasquelle verbunden ist.From EP-Bl 0 919 460 of the applicant, a buoyancy aid for watercraft in distress with at least one swimming bag is known. Inside the watercraft are floating bags, each of which is inflatable by a gas source. The swimming bags are connected to the watercraft by a bondage. This requires that each swimming bag is separately connected to an external gas source.
Um eine platzsparende und leitungsunabhängige Auftriebshilfe zu haben, ist anzustreben, dass der Gasgenerator im Inneren des Schwimmsackes liegt.In order to have a space-saving and line-independent buoyancy aid, the aim should be that the gas generator is located inside the swimming bag.
Aufgabe der Erfindung ist es, den Schwimmsack so an dem Modul und damit an der Aufnahme zu befestigen, dass in der Sackwand an der Befestigungsstelle möglichst kleine bzw. keine Schubspannungen auftreten, sondern nur Zugspannungen.The object of the invention is to attach the swimming bag to the module and thus to the receptacle in such a way that as little or no shear stresses as possible occur in the sack wall at the attachment point, but only tensile stresses.
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 in accordance with the characterizing features of claim 1. Advantageous developments of the invention can be found in the subclaims.
Die Befestigung des Schwimmsacks am zylindrischen Zapfen ist sehr einfach. Der Schwimmsack hat unten eine Öffnung. Die Öffnung ist durch einen Keder begrenzt. Der Keder wird in einfacher Weise in eine Halbkreis-Kehle des Zapfens geschoben. Dann wird ebenfalls in einfacher Weise das untere Gegenstück, das ebenfalls eine Halbkreis-Kehle aufweist, aufgeschoben. Zwischen dem Fuß und dem Gegenstück in der Form eines Basiskörpers besteht durch eine entsprechende Passverbindung eine feste, nicht mehr lösbare Verbindung.Attaching the swimming bag to the cylindrical spigot is very easy. The swimming bag has an opening at the bottom. The opening is through a piping limited. The piping is simply pushed into a semicircular throat of the pin. Then the lower counterpart, which also has a semicircular groove, is also pushed on in a simple manner. Between the foot and the counterpart in the form of a base body there is a fixed, no longer detachable connection by means of a corresponding fitting connection.
Das Einbringen des zylindrischen Zapfens in den Schwimmsack erfolgt durch eine Öffnung am oberen Ende des Schwimmsackes, wobei diese Öffnung anschließend gas- und wasserdicht durch Vulkanisieren oder Kleben oder eine sonstige Befestigung verschlossen wird.The cylindrical peg is introduced into the swimming bag through an opening at the upper end of the swimming bag, this opening then being closed in a gastight and water-tight manner by vulcanizing or gluing or other fastening.
Wesentlich ist auch die formschlüssige Vorprägung der Form des Schwimmsackes während und nach dem Aufblasen. Dies bewirkt die etwa schalenförmige Außenfläche einer teilzylindrischen Wanne, wobei die Innenseite der Wanne der Lagerung und Befestigung des Gasgenerators dient. Diese Wanne bewirkt die maximale Ausdehnung des Schwimmsacks in einer Ebene. Und zwar nicht als schmaler Schlauch sondern in Form einer Ellipse. Rechtwinklig dazu ist die Ausdehnung des Schwimmsackes eine schmälere Ellipse. Der Vorteil des derartigen Schwimmsackes besteht darin, dass er im aufgeblasenen Zustand bei einer Leckage des Wasserfahrzeugs in einer seiner beiden Ebenen relativ schlank ist und dadurch in noch freie Lücken zwischen anderen Schwimmsäcken oder zwischen schiffseitigen Ein- und Anbauten sich selbsttätig einfädelt.Also essential is the positive pre-embossing of the shape of the swimming bag during and after inflation. This causes the approximately shell-shaped outer surface of a partially cylindrical trough, the inside of the trough serving for mounting and fastening the gas generator. This pan causes the maximum expansion of the swimming bag on one level. And not as a narrow tube but in the form of an ellipse. At right angles to this, the expansion of the swimming bag is a narrower ellipse. The advantage of such a swimming bag is that it is relatively slim in the inflated state if there is a leak in the watercraft in one of its two levels and thereby automatically threads itself into free gaps between other swimming bags or between ship-side fittings and attachments.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigt:An embodiment of the invention is shown in the drawing. It shows:
Figur 1 einen aufgeblasenen Schwimmsack in einer Seitenansicht,FIG. 1 shows an inflated swimming bag in a side view,
Figur 2 den Schwimmsack nach Figur 1 in einer Vorderansicht undFigure 2 shows the swimming bag of Figure 1 in a front view
Figur 3 eine Einzelheit nach Figur 1.FIG. 3 shows a detail according to FIG. 1.
An der Innenwand 1 eines Wasserfahrzeuges 3 ist an einer Montageplatte 5 ein Basiskörper 7 über eine pyrotechnisch auslösbare Trennschraube 9 mit der Montageplatte 5 fest verbunden. In einem Hohlraum 11 des Basiskörpers 7 ist neben der Trennschraube 9 ein aufgewickeltes Seil 13 gelagert. Das Seil 13 ist sowohl mit der Montageplatte 5 als auch mit dem Basiskörper 7 verbunden.On the inner wall 1 of a watercraft 3, a base body 7 is fixedly connected to the mounting plate 5 via a pyrotechnically releasable separating screw 9 on a mounting plate 5. In a cavity 11 of the base body 7, a coiled rope 13 is mounted next to the separating screw 9. The rope 13 is connected both to the mounting plate 5 and to the base body 7.
In einem weiteren Hohlraum 15 des Basiskörpers 7 liegt ein zylindrischer Zapfen 17 eines Aufiiahmekörpers 19.In a further cavity 15 of the base body 7, there is a cylindrical pin 17 of a receiving body 19.
In einer teilzylindrischen Wanne 21 mit entsprechend gewölbter Außenfläche 22 ist ein zylindrischer Gasgenerator 23 befestigt.A cylindrical gas generator 23 is fastened in a partially cylindrical trough 21 with a correspondingly curved outer surface 22.
Ein Packsack 25 hüllt sowohl einen zusammengefalteten Schwimmsack 27 als auch den darin angeordneten Gasgenerator 23 ein. Der Packsack 25 ist bei 29 unterhalb eines aufgeweiteten Abschnitts 31 des Basiskörpers 7 wasser- und gasdicht an dem Basiskörper 7 befestigt.A stuff sack 25 envelops both a folded swimming bag 27 and the gas generator 23 arranged therein. The pack sack 25 is attached to the base body 7 in a water-tight and gas-tight manner at 29 below a widened section 31 of the base body 7.
In einer Ausnehmung 33 ist ein Keder 35 des Schwimmsackes 27 gelagert. Die Ausnehmung 33 ist durch entsprechende Kehlnuten 37, 38 am Basiskörper 7 und am Aufnahmekörper 19 gebildet.A piping 35 of the swimming bag 27 is mounted in a recess 33. The recess 33 is formed by corresponding fillet grooves 37, 38 on the base body 7 and on the receiving body 19.
Zur Montage des Aufnahmekörpers 19 wird dieser durch eine Öffnung 50 am oberen Ende des Schwimmsackes 27 eingeführt und in die Öffnung 18 bis zum Anschlag am Keder 35 gesteckt. Der Keder 35 liegt dann in der Kehlnut 38. Anschließend wird der Basiskörper 7 in einfacher Weise in Richtung des Pfeiles 65 auf den zylindrischen Zapfen 17 des Aufnahmekörpers 19 bis zum Anschlag am Keder 35 aufgeschoben.To mount the receiving body 19, this is inserted through an opening 50 at the upper end of the swimming bag 27 and inserted into the opening 18 up to the stop on the piping 35. The piping 35 then lies in the fillet groove 38. The base body 7 is then pushed in a simple manner in the direction of the arrow 65 onto the cylindrical pin 17 of the receiving body 19 until it stops on the piping 35.
Der Keder 35 liegt in Zugrichtung 67 des Schwimmsackes 27 formschlüssig an den ringförmigen Nasen 36, 39 an. Zwischen den Nasen 36, 39 ist ein Ringspalt 42. Im Ringspalt 42 liegt mit seitlichem Spiel der Schwimmsack 27. Frei von Querkräften, siehe Pfeil 69, liegt der Schwimmsack 27 im Ringspalt 42. Der Zapfen 17 und der Basiskörper 7 sind durch eine entsprechende Passung fest miteinander verbunden. Es können auch sonstige Befestigungsmittel vorgesehen sein.The piping 35 bears in a form-fitting manner against the annular noses 36, 39 in the pulling direction 67 of the swimming bag 27. Between the lugs 36, 39 there is an annular gap 42. In the annular gap 42, the swimming bag 27 lies with lateral play. Free of transverse forces, see arrow 69, the swimming bag 27 lies in the annular gap 42. The pin 17 and the base body 7 are firmly connected to one another by a corresponding fit. Other fastening means can also be provided.
Sowohl der Abschnitt 61 des gefalteten Schwimmsackes 27 als auch der genannte Abschnitt 61 des vollständig aufgeblasenen Schwimmsackes 27 liegen formschlüssig in der in Figur 2 gezeigten Ebene an der gewölbten Außenfläche 22 an als auch in der um 90° versetzten Ebene an den Radien 43 des Gasgenerators 23, siehe Figur 1. Dadurch ist gewährleistet, dass im aufgeblasenen Zustand des Schwimmsackes 27 an der Befestigungsstelle möglichst kleine bzw. keine Schubspannungen auftreten, sonder nur Zugspannungen. Kritische Bruchzonen des Schwimmsackes 27 werden dadurch vermieden.Both the section 61 of the folded swimming bag 27 and the above-mentioned section 61 of the fully inflated swimming bag 27 rest positively on the curved outer surface 22 in the plane shown in FIG. 2 and on the radii 43 of the gas generator 23 in the plane offset by 90 ° , see Figure 1. This ensures that, when the floating bag 27 is inflated, as little or no shear stresses occur at the attachment point, but only tensile stresses. Critical breaking zones of the swimming bag 27 are thereby avoided.
Funktionsablauf:Functional sequence:
Zur Verdrängung des Wassers im Innenraum 2 wird der Gasgenerator 13 elektrisch gezündet. Der noch gefaltete Schwimmsack 27 beginnt sich mit Gas zu füllen und dehnt schließlich den Packsack 25 soweit aus, bis dieser an einer nicht gezeichneten Sollbruchstelle bricht und den Schwimmsack 27 frei gibt. Das Gas des Gasgenerators 23 tritt an einer Öffnung 41 des Gasgenerators 23 aus und tritt unmittelbar in den Schwimmsack 27 ein.In order to displace the water in the interior 2, the gas generator 13 is ignited electrically. The still folded swimming bag 27 begins to fill with gas and finally expands the packing bag 25 until it breaks at a predetermined breaking point (not shown) and releases the swimming bag 27. The gas of the gas generator 23 exits at an opening 41 of the gas generator 23 and enters the swimming bag 27 directly.
Aufgrund des zunehmenden Gasvolumens des Schwimmsackes 27 birst der Packsack 25 und der Schwimmsack 27 entfaltet sich bis zu seiner gezeichneten Endgröße. Das Wasser wird entsprechend verdrängt und der Auftrieb durch den gefüllten Schwimmsack 27 bewirkt.Due to the increasing gas volume of the swimming bag 27, the stuffing bag 25 bursts and the swimming bag 27 unfolds to its final size. The water is displaced accordingly and the buoyancy is brought about by the filled swimming bag 27.
Nach etwa 0,2 Sek. wird die Trennschraube 9 elektrisch gezündet und gibt den Basiskörper 7 frei. Der Schwimmsack 27 steigt mit diesem auf und wird durch das Seil 13 gehalten.After approximately 0.2 seconds, the separating screw 9 is ignited electrically and releases the base body 7. The swimming bag 27 rises with it and is held by the rope 13.
Wesentlich ist für die Befestigung des Schwimmsacks 27, dass ab dem Keder 35 der Schwimmsack 27 durch die Außenfläche 22 der teilzylindrischen Wanne 21 geführt wird. Schwankungen des Schwfmmsackes 27 oder extreme Lageänderungen des Schwimmsackes 27 führen zu keinen Knicken am Schwimmsack 27. Dazu trägt auch der zylindrische Gasgenerator 23 - siehe Figur 1 - als auch die Radien 43, 45 am Gasgenerator 23 bei.It is essential for the attachment of the swimming bag 27 that, starting from the piping 35, the swimming bag 27 is guided through the outer surface 22 of the partially cylindrical tub 21. Fluctuations in the floating bag 27 or extreme changes in the position of the swimming bag 27 do not lead to kinking Swimming bag 27. The cylindrical gas generator 23 - see FIG. 1 - and the radii 43, 45 on the gas generator 23 also contribute to this.
Zur Montage des Gasgenerators 23 und des Aufnahmekörpers 19 ist der Schwimmsack 27 mit einem aufklappbaren Lappen 49 versehen. Dieser überdeckt eine Öffnung 50. Der überstehende Lappen 51 ist mit dem Basissack 47 fest und gasdicht verbunden. To assemble the gas generator 23 and the receptacle body 19, the floating bag 27 is provided with a flap 49 that can be opened. This covers an opening 50. The projecting tab 51 is connected to the base bag 47 in a fixed and gas-tight manner.
