Abstract

Lifeboat with launching device, in which the lifeboats are arranged in a lifeboat deck in the transverse direction of the ship on a transport platform inclined towards the ship's side and can be moved outside of the hull, characterized in that the lifeboat deck (2) is closed on the side by means of hatches (7) that can be opened outwards, wherein the hatches (7) are hinge-like connected to the transport platform (6) so that the hatches (7) extend the transport platform (6) on the outside of the ship in the unfolded state and the transport platform (6) and the hatches (7) provide a continuous transport path for the Form lifeboat (4).

Description

The invention relates to a lifeboat assembly and the deployment of lifeboats in the transept direction, the lifeboats are arranged in a lifeboat deck.

Such an arrangement of lifeboats is from the FR 741 841 known. Here buoyant receptacles are arranged like a drawer in the ship's side wall. These are moved out if necessary by means of a roller and rope assembly from the hull. A disadvantage of this solution is that the exposure is technically complex and at a heeling the receptacle can already be below the waterline and on the other side of the ship, the extension must be made upward. Another disadvantage is that the exposure takes place directly on the side wall.

With similar disadvantages, the lifeboat arrangement is according to US 1,133,700 afflicted.

The DE 44 31 542 A1 proposes to overcome these disadvantages, to use a rigid pathway with roller bearings U-beams, which are driven when needed to extend the rolling track to the outboard. The rolling track has an inclination of 30 °.

The disadvantage is that the lifeboat deck is open to the outside, which makes the rescue work difficult. Furthermore, the extension of the rolling track, which is driven outboard, the same angle of inclination, so that with a corresponding heeling the drop height can reduce so that immersion of the lifeboats during extension is possible, which can lead to a levering out of the runway , with the result of a collision of the lifeboats with the side wall.

The extension of the rolling track is therefore possible only under certain conditions, what in the DE 44 31 542 A1 is expressly noted.

The object of the invention is to propose a lifeboat arrangement, which does not have the aforementioned disadvantages when exposing the lifeboats.

This object is achieved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

For lifeboats with suspending device, the lifeboats are arranged in a rescue boat deck in a direction transverse to the ship's side inclined transport platform and moved to outside the hull, the invention proposes that the lifeboat deck is closed on the side wall hatch to the outside hatch, the hatches with hinges the transport platform are connected so that the hatches in the unfolded state extend the transport platform outside of the ship and the transport platform and the hatches form a continuous transport path for the respective lifeboat.

The lifeboat deck is closed during normal driving. The lifeboats are not exposed to environmental influences. The lifeboats can be safely reached from within the ship. In the event of an accident, the hatches are opened at an angle which is preferably in accordance with the angle of inclination of the transport platform. The result is a continuous transport path, which preferably has roles on which the respective lifeboat can leave the hull.

In a preferred embodiment, the inclination angle of the transport platform is adjustable, so that in a heeling optimal angular adjustment of the transport path is adjustable.

In a further embodiment, it is provided that an additional force in the transept direction can be exercised on the lifeboats. This can already act on the lifeboats if the lifeboats are still fixed by a detachable anchorages in the lifeboat deck or activated only with the release of the anchorage.

The lifeboats move not only by gravity in ship's transverse direction but get an initial acceleration.

In a preferred embodiment, the additional force is applied by an air cushion between a wall of the lifeboat deck and the stern of the lifeboat. The air cushion is inflated after the fixation of the lifeboat or in case of application in a similar manner as an airbag.

In an advantageous embodiment in which the access to the lifeboat rear side is provided by a passage from a escape lane in Rettungsbootdeckhöhe through the wall of the lifeboat deck in the rear of the lifeboat, the passage can be circumferentially sealed by a then annularly shaped air cushion or. This ensures that flooding of the lifeboats or the ship through the entrances to the escape corridor is safely avoided, even at high seas and open hatches.

After closing the access to the watertight cabin of the lifeboat and the Access to the escape corridor anchoring can be solved and the lifeboat is accelerated by the now expanding annular air cushion in the transverse direction.

By controlling the amount of air in the air cushion, the acceleration variable is also adjustable, which provides a further embodiment.

When moving the lifeboat in the transept direction, it is preferably stabilized by lateral guide rollers.

The lifeboats have a water-tight lockable cabin for the passengers or are a watertight lockable cabin.

In a preferred embodiment, the lifeboats have a front floor slope.

An embodiment is shown in the drawing and will be explained below.

The figure shows a ship's hull 1 in cross-section with the lifeboat deck 2 with one in the lifeboat deck 2 arranged lifeboat 4 , The lifeboat 4 is in the lifeboat deck 2 in transept direction 10 on a transport platform inclined towards the ship's side 6 arranged and by means of releasable anchoring 12 established.

The lifeboat deck 2 is on-board side by hatch hinged outwards 7 closed, with the hatches 7 hinged 8th with the transport platform 6 are connected, so the hatches 7 in the unfolded state, the transport platform 6 extend the outside of the ship and the transport platform 6 and the hatches 7 a continuous transport lane for the lifeboat 4 form. Shown here is just a hatch 7 ,

The transport railway, the transport platform 6 and the hatch 7 , show roles 9 on top of that the lifeboat 4 in transept direction 10 is movable.

Because the angle of inclination of the transport platform 6 adjustable, can be the inclination angle of the transport platform 6 as well as the hatch 7 and thus the transport path to an optimal deployment of the lifeboat 4 to adjust.

In the illustrated arrangement is on the lifeboat 4 an additional force in the transept direction 10 exercisable. The additional power goes from the air cushion 13 between the wall of the lifeboat deck 2 and the stern of the lifeboat 4 out. The rear access to the lifeboats 4 that's from a passage 5 from a flight corridor 3 in lifeboat deck height through the wall of the lifeboat deck 2 in the stern of the lifeboat 4 is formed, is circumferentially through the annular air cushion 13 sealed. After closing the access to the waterproof cabin of the lifeboat 4 and access to the escape corridor 3 becomes the anchorage 12 solved and the lifeboat 4 is due to the now expanding annular air cushion 13 in transept direction 10 accelerated.

The lifeboats 4 even have a waterproof lockable cabin for the passengers or consist of a watertight lockable cabin. Access to the lifeboats 4 is preferably arranged as explained above lifeboat side. Front side, the lifeboats point 4 a floor slope 11 on.

The lifeboats 4 are through the releasable anchoring 12 in the lifeboat deck 2 fixed and during the movement in the transept direction 10 they are stabilized by lateral guide rollers.

With the proposed lifeboat arrangement, the rear-sealed accessibility, the acceleration option for the lifeboats 4 and those through the hatches 7 prolonged removal of the lifeboats 4 including the adjustment of the transport path are optimal conditions for both the storage of the lifeboats 4 as well as their occupation and application.
