Description

The present invention relates to a floating dock according to the preamble of claim 1.

In the sailor language, a cover is any type of waterproof cover made of impregnated fabric that has been tailor-made for a specific purpose. Tarpaulins are usually made of plastic, such as PVC and polyester.

Floating docks are known from the state of the art recently. As a rule, they have a platform (eg a so-called ground pontoon), on which side flotation tanks connect. To introduce the ship into the floating dock, the tanks are flooded and the platform sags. After reaching the required clearance above the platform, the ship is pulled by means of winds in the floating dock. After reaching the correct position, the ship is held so that it is located approximately in the middle of the floating dock. Then the tanks of the docks are steered (pumped empty), which raises the floating dock and the ship is exposed. As a rule, for this purpose, palls (wooden supports) are used, which cling to a slight curvature of the ship's bottom. Mostly floating docks are installed in the docks, but there are also self-propelled pontoons, where a permanent settling on the bottom of a harbor does not take place.

From the US 2005 0 139 141 A1 a floating dock is known, which consists of a supporting support device as well as a watercraft completely or only partially superior cover. The cover has a frame for a cover. The cover is raised in a downward movement of the support of the vessel and lowered at an upward movement. Here, the raising and lowering of the cover takes place synchronously opposite to the movement of the displacement tank by means of a connecting device connecting the cover and the support device.

The disadvantage is that the erection of the cover in synchronism with the downward movement due to the weight of the cover via a pulling or lifting device, for example. A pulley, must be done.

The invention is based on the object, in a floating dock on both constructive and in terms of handling simple and fast way to allow raising or lowering of the cover.

According to the invention the above object is achieved with the features of claim 1. Advantageous embodiments of the floating dock according to the invention are specified in the subclaims.

Other objects, features, advantages and applications of the floating docks will become apparent from the following description of an embodiment with reference to the drawings.

In the drawings show

1 a preferred embodiment of a floating dock in a side view, with a closed cover,

2 the floating dock in side view, opened,

three the floating dock in the top view.

Like from the 1 . 2 seen, are the cover three or a preferred frame 3a for a tarpaulin 3b and the displacement tanks 1 preferably via one or more joints 6 head side together on a support device 2 connected. The support device 2 preferably consists of a base 2a to which the displacement tanks 1 and a watercraft 4 carrying other facilities are arranged.

The cover 3b is over several cross struts 7 on a rotating frame 3a made of aluminum. The frame 3a is the head of the floating docks over the joints 6 hinged.

When lowering the floating docks are floating in or on the water elongated float 8th pulled down on one side. These swimmers 8th are pivotable on the support device 2 or the displacement tanks 1 arranged and automatically align themselves when lowering the floating dock. At the free end of the float 8th (Upper side) are as connecting device 5 rods 9 provided, via joints such with the frame 3a and the floats 8th connected are that the frame 3a when raising the floats 8th straighten up (see 2 ).

In a particularly preferred embodiment, ballast tubes filled with water are additionally provided on the floating dock 10 intended. The water ballast in these ballast pipes 10 puts on the power, the support device 2 with the displacement tanks 1 and the joint swimmers 8th even under water when there is no boat on the floating dock, as a result over the poles 9 the cover three is raised. The ballast in these ballast pipes 10 is lifted with the floating dock over the water level. The water ballast is when lowering the floating dock by dipping the ballast tubes 10 continuously less and completely raises in the lowered position.

The buoyancy of the articulated floats 8th limits the depth of the floating dock and prevents it from capsizing.

The connection device 5 Instead, it can also be achieved, for example, by means of toothed wheels, which are located above the joint 6 when tilting at least one displacement tank 1 an opposite tilting movement of the frame 3a and thus cause a "unfolding". In addition, all other known from the prior art measures come into consideration, for the production of a nearly synchronously hinged or otherwise different connection for lifting the cover three and lowering the support device 2 are suitable.

As a support device 2 All facilities that allow a resting and lifting of watercraft of any type are considered.

Furthermore, also the displacement tanks 1 even as a supporting support device 2 be formed without a further constructive device - for example, a frame construction - would be required.

As the 1 - three can show the layout of the displacement tanks 1 done in different ways. So these can be in the longitudinal direction of the support device 2 and / or be oriented almost perpendicular thereto.
