Abstract

The invention provides a flexible envelope which is wrapped around the hull to leave a space between the envelope and the hull, to be filled with water/antifreeze mixt. The bottom of the envelope is ballasted to hold it under the keel while the top ends are spaced away from the sides of the hull by an inflated collar. This is positioned about the waterline and is held in place by elastic ties between the envelope and the top of the hull, where a webbing system secures the ties. The invention enables the boat to be left in the water over the winter. It can also be used to store boats for a time without the hull fouling, by adding protective fluids to the water jacket.

Description

Die F i g. 1 zeigt ein im Wasser 1 liegendes Segelboot 2, bei dem der Rumpf mit 3, dessen Kiel mit 4, die Aufbauten mit 5 und die Masten mit 6 bezeichnet sind. The F i g. 1 shows a sailing boat 2 lying in the water 1, in which the hull with 3, its keel with 4, the superstructure with 5 and the masts with 6 are.

Dieser in den F i g. 1 und 2 in der Stirn- und Seiten- This in the F i g. 1 and 2 in the front and side

ansicht dargestellte Bootsrumpf 3 ist weiterhin von einer aus einer wasserdichten Kunststoffolie bestehenden Tasche 7 umgeben, deren Gestaltung sowohl dem Querschnitt als auch dem Längsriß des Bootsrumpfes 3 angepaßt ist. Desgleichen ist es natürlich auch möglich, nur eine grobe Anpassung der Tasche 3 vorzunehmen, wie dieses in der F i g. 2 gestrichelt dargestellt ist.boat hull 3 shown is still from one of a watertight plastic film surrounding the existing bag 7, the design of both the cross section as well as the longitudinal view of the boat hull 3 is adapted. Likewise it is of course also possible to make only a rough adjustment of the pocket 3, like this one in FIG. 2 is shown in dashed lines.

An dem mit 8 bezeichneten Rand dieser Tasche 7 ist weiter ein beispielsweise im Querschnitt kreisförmiger Luftschlauch 9 gegebenenfalls lösbar angeordnet, der als Tragwulst dient und aus Sicherheitsgründen in einzelne mit 10 bezeichnete Luftkammern unterteilt ist. At the edge of this pocket 7, denoted by 8, there is also an example Circular air hose 9 optionally detachably arranged in cross section, the serves as a support bead and, for safety reasons, in individual air chambers designated 10 is divided.

Diese Luftkammern 10 sind dabei so weit mit Luft aufzublasen, daß in diesen ein Überdruck herrscht, der wieder ein enges Anliegen des Luftschlauches 9 an der Außenfläche 11 des Rumpfes 3 und damit eine sichere Abdichtung des von der Tasche 7 umgebenen, mit 12 bezeichneten Zwischenraumes bewirkt. Der Durchmesser D dieses Luftschlauches ist dabei so bemessen und eine Ballasteinlage derartig eingearbeitet, daß sein Tiefgang t größer ist als der einer sich eventuell im Winter bildenden Eisschicht maximaler Stärke. Durch diese Abmessung des Luftschlauches 9 ist es also gewährleistet, daß das Eis allein mit der Außenseite des Luftschlauches 9, nicht aber mit der Außenfläche 11 des Bootsrumpfes 3 in Berührung kommen kann.These air chambers 10 are to be inflated with air so far that in these there is an overpressure, which again a tight fit of the air hose 9 on the outer surface 11 of the fuselage 3 and thus a secure seal of the the pocket 7 surrounded by 12 designated space causes. The diameter D this air hose is dimensioned in such a way and a ballast insert is incorporated in such a way that that its draft t is greater than that of one that may develop in winter Ice layer of maximum thickness. So it is through this dimension of the air hose 9 ensures that the ice alone with the outside of the air tube 9, not but can come into contact with the outer surface 11 of the boat hull 3.

Obwohl die Tasche 7 bereits durch den Luftschlauch 9 an dem Rumpf 3 festgehalten wird, so können weiterhin noch in Abständen voneinander an dem Luftschlauch 9 mit 13 bezeichnete Leinen befestigt sein, mittels denen sich der Luftschlauch 9 zusätzlich entweder am Oberrand 14 des Freibordes 15 oder aber am Deck 16 befestigen läßt. Although the bag 7 is already attached to the fuselage through the air hose 9 3 is held, so can still be spaced from each other on the air hose 9 with 13 designated lines attached, by means of which the air hose 9 also fasten either to the upper edge 14 of the freeboard 15 or to the deck 16 leaves.

Wie aus dem rechten Teil der F i g. 1 zu ersehen ist, so kann dieser Luftschlauch 9 aber auch einen ovalen Querschnitt aufweisen und zur Abdeckung der über- wiegenden Fläche des Freibordes 15 nahe bis an den Oberrand 14 des Freibordes 15 hochgezogen sein. Diese Aiternative zeichnet sich weiterhin dadurch aus, daß auch der in diesem Fall mit 17 bezeichnete Taschenrand hochgezogen ist und über die Oberkante 14 des Freibordes 15 herumgreift. Hierbei kann dieser Taschenrand 17 in einen nicht besonders dargestellten Saum auslaufen, in dem eine Halteleine eingezogen ist, mittels der der Taschenrand 17 sich so weit zusammenziehen läßt, daß ein Herabrutschen desselben über den Oberrand 14 des Freibordes 15 nicht mehr möglich ist. As shown in the right part of FIG. 1 can be seen, this can Air hose 9 but also have an oval cross-section and to cover the above- weighing surface of the freeboard 15 close to the upper edge 14 of the freeboard 15 be pulled up. This alternative is further characterized by the fact that also the pocket edge designated in this case with 17 is pulled up and over the upper edge 14 of the freeboard 15 reaches around. Here this pocket edge 17 run out in a not particularly shown hem in which a tether is drawn in, by means of which the pocket edge 17 can be pulled together so far, that the same sliding over the upper edge 14 of the freeboard 15 is no longer is possible.

Gemäß der F i g. list außerdem an die Tasche 7 mittels eines an diesen angeschweißten Stutzens 18 ein mit 19 bezeichneter Schlauch angeschlossen, über den das in dem Zwischenraum 12 befindliche Wasser 20, insbesondere Salzwasser, abgesaugt und gegebenenfalls durch Luft oder aber Süßwasser ersetzt werden kann. According to FIG. list also to the pocket 7 by means of one to this welded nozzle 18 connected to a hose designated 19, over which the water 20 located in the space 12, in particular salt water, is sucked off and can optionally be replaced by air or fresh water.

Ist weiterhin in dem den Kiel 4 umgebenden Boden 21 der Tasche 7 ein mit 22 bezeichnetes Rückschlagventil angeordnet, so läßt sich beispielsweise über den durch ein nicht dargestelltes Ventil absperrbaren Schlauch 19 in den Zwischenraum 12 Luft eindrücken, wobei dann das bisher in diesem Zwischenraum 12 befindliche Wasser 20 durch das Rückschlagventil 22 nach außen abströmt. Sobald nun der Zwischenraum 12 vollständig mit Luft ausgefüllt ist, läßt man diese wiederum durch den Schlauch 19 nach außen entweichen, so daß der äußere Wasserdruck nunmehr die Tasche 7 fest an die Außenwandung des Rumpfes 3 preßt, der sodann von einer durch die Tasche 7 gebildeten Schutzhaut und somit auch gegenüber jeden Algenbefall geschützt ist. Is also in the bottom 21 of the pocket 7 surrounding the keel 4 a check valve designated by 22 is arranged, for example Via the hose 19, which can be shut off by a valve (not shown), into the space 12 press in air, then the one previously located in this space 12 Water 20 flows through the check valve 22 to the outside. As soon as the space in between 12 is completely filled with air, this is again allowed through the hose 19 escape to the outside, so that the external water pressure now secures the pocket 7 presses against the outer wall of the fuselage 3, which is then pressed by a through the pocket 7 formed protective skin and is thus protected against any algae infestation.

Desgleichen bleibt aber auch die Wirkung des den Rumpf 3 umgebenden Luftschlauches 9 erhalten, der den Rumpf 3 vor jeder Berührung mit dem Eis sowie auch vor jeder Eispressung schützt. The effect of the one surrounding the fuselage 3 remains the same Air hose 9 received, the fuselage 3 before any contact with the ice as well also protects against any ice squeezing.

5. Device according to claim 4, characterized in that the pocket edge (17) around the upper edge (14) of the freeboard (15) and into an endless one Hem expires, in which a tether is drawn, both ends of which from the Protruding hem.

The invention relates to an od to protect the hull of a boat. Like. Suitable device that consists of a the fuselage from below at least up to surrounding the waterline, made of a waterproof sheet-like material or the like. manufactured bag, the edge of which in a surrounding the hull of the boat, similar to a hose designed and buoyant bearing bead expires.

Before the cold season sets in, sailboats and motorboats are used of all types and sizes generally drawn ashore, on specially designated Berths jacked up and protected against external weather influences such as rain, snow and wind, covered. Apart from the fact that both the landing of the boats as also the need to re-launch them in the spring is extraordinary is laborious and cumbersome, there is also the further difficulty that there is often a lack of the necessary berths.

To avoid these hardships, one could of course also leave the boat in question in the water during the winter. Such a hibernation in the water, however, there is a great risk that not only the outer surface the hull of the boat was damaged by ice, but also the entire hull is even destroyed by the pressure exerted by the ice. It also trains During the winter, algae accumulate on the outer surface of the boat hull, which must be laboriously removed again in spring.

By US Patents 32 05 851 and 31 42 283 are from a waterproof film or the like. Existing pockets to be introduced into the water have become known, which od the hull of a boat lying in the water. Like. Up to the water line and thus protect against vegetation and mud or cleaning the boat hull without having to pull the boat out of the water. To the bracket these pockets are either provided with a floating bearing bulge lying in the water or it is the edge of the pocket by means of special brackets on the freeboard attached to the boat in question.

Since these previously known bags thus only provide protection against vegetation or also represent sludge, the invention is based on the object of such To train the bag so that it is also suitable as winter protection, any damage the hull of the boat is prevented by the pressure exerted by the ice and thus hibernation of the boat in the water.

This object is achieved according to the invention in that the Support bead as an elastic air hose with a circular or a non-circular one Cross-section is formed and a ballast insert is incorporated into it, that its draft is greater than that of a layer of ice that may form in winter maximum strength.

This bearing bead, designed as an elastic air hose, comes so to the extent that it has a double function, as on the one hand it is supposed to carry the bag, on the other hand, however, when it is filled with air, due to its elasticity inflates and thus rests so tightly on the boat hull that it is the boat hull surrounding elastic cushion that not only prevents water and water from penetrating thus also prevents the formation of ice between its outside and the boat hull, but also any pressure directed against the boat in winter forming ice layer and so any damage to the boat hull through prevents this ice pressure occurring in winter. The one introduced into the bearing bead Ballast insert ensures that the bearing bead is actually between the The hull of the boat and the layer of ice that forms in winter comes to rest, being The draft is then still greater than the maximum strength of this itself in winter forming layer of ice.

In a particularly expedient design of this according to the invention The air hose is arranged on the inside of the edge of the bag. The air hose can also be close to the upper edge of the freeboard be pulled up.

In addition, there is also the possibility that the edge of the pocket is pulled up over the air hose and at least to the upper edge of the freeboard reaches or reaches around the top of the freeboard and into an endless seam expires, in which a tether is then drawn in, both ends of which from the Protruding hem.

In the drawing is an example embodiment of the invention Protective device shown. It shows F i g. 1 shows a cross section of the device with the hull of a sailing boat surrounding it and F i g. 2 the side view of the sailboat with the facility surrounding the boat hull.
