Description

Facility for transporting motor vehicles on water surfaces

The invention relates to a device for transporting motor vehicles on water surfaces, in particular in the event of a disaster, for example in the event of a sudden, short-term flooding of parking areas and the like.

As is well known, motor vehicles are transported across water surfaces using larger vessels specially designed for this purpose, such as ferries and the like. These are designed as single-purpose equipment and are usually tied to certain minimum dimensions of the fairway in which they operate.

These cannot be used in the event of a disaster in shallow waters. Furthermore, ramps and/or lifting devices are required to be able to move the vehicles onto the deck of the vessel.

According to DE-OS 26 18 343, it is also known to bring a motor vehicle onto the deck of a ship and to move the drive device via a friction wheel drive or via a drive flanged to one of the two axle flanges. Furthermore, a device is described in which a light trailer of a motor vehicle has a boat drive and a fold-out raft-like platform for transporting the motor vehicle. Furthermore, there are floating bodies that carry the entire device, including the load, on the water surface.

Such a compact, single-purpose facility has extensive mechanical equipment and is neither quickly dismantled nor quickly relocated and cannot be used for rescue operations to rescue a motor vehicle. In addition, there must be a ramp over which the motor vehicle can drive up if it cannot be placed on top using a lifting device.

The object of the invention is therefore to create a device which can be dismantled into individual parts and which enables a motor vehicle to be lifted and simultaneously made buoyant on site in a way that prevents it from tipping over if it unexpectedly and unmaneuverably ends up in shallow water. At the same time, the device should be usable as a temporary buoyancy aid.

The problem is solved by a device which is formed from a horizontally U-shaped, gas-fillable hose-like body, in which the clear part formed by the U-shaped, gas-fillable hose-like body is preferably wider in terms of its clear width than the width of a motor vehicle to be transported and the clear length is preferably longer than the wheelbase of the motor vehicle to be transported, and cross members supporting the motor vehicle rest on the two legs of the U-shaped, gas-fillable hose-like body. According to an expedient embodiment of the invention, the two legs adjoining the open side of the U-shaped, gas-fillable hose have reinforcements on their upper side on which the cross members rest.

Likewise, the cross-members can have widenings at both ends adapted to the upper side of the legs of the U-shaped, gas-fillable hose-like body and can be designed to be lockable there.

and stored. This can be done, for example, by having the reinforcements of the U-shaped, gas-fillable tube-like body have raised areas to which recesses in the widenings of the cross members are assigned.

According to a preferred variant, the cross members are initially bent upwards at both ends in the support area and then the profile of the legs adjoining the open side of the U-shaped, gas-fillable, hose-like body is bent comprehensively, so that the projected surface supporting the motor vehicle to be transported is arranged lying between these legs with respect to the vertical.

It goes without saying that the dimensions of the tube-like body that can be filled with gas are based on the intended load and the expected buoyancy. The cross members are also dimensioned according to the expected static load and the corresponding required section modulus.

According to a further preferred variant, the motor vehicle to be transported is arranged with its longitudinal axis in the longitudinal extension of the U-shaped, gas-fillable hose-like body. At least one known rudder is arranged at the open end of the U-shaped, gas-fillable hose-like body, and at least one of the steerable wheels of the motor vehicle to be transported is connected to a crosspiece of a cable pull device that operates the rudder. It goes without saying that it is also possible to connect both steerable wheels to a crosspiece each. It is also possible in all cases for a

The device can therefore be controlled via the motor vehicle being transported.

Furthermore, the cross-beam arranged near the drive wheels can have friction rollers which are moved by the drive wheels of the motor vehicle to be transported and which are connected to an angle gear which rotates a ship's propeller, so that the propulsion of the entire device is carried out by the drive unit of the motor vehicle to be transported.

Such a device can be used to great advantage in the event of unforeseen flooding, or as an additional device for specific applications where vehicles have to be moved over water for a short time. To make this possible, the horizontal U-shaped tube-like body that can be filled with gas is laid out around the vehicle, the crossbars are pushed under the vehicle and the tube-like body is filled with gas under pressure. Care must be taken to ensure that the crossbars assume their predetermined position in relation to the U-shaped tube-like body. Once a sufficient amount of gas has been filled, the vehicle floats and can be maneuvered in any way. The lightweight construction of the device allows the entire device to be maneuverable. As it consists of individual parts and can be assembled, transport to and assembly at the site is uncomplicated. Instead of an auxiliary drive from the vehicle to be transported, the movement can also be carried out by a suitable towing device.

The invention will be described in more detail below using an exemplary embodiment. The accompanying drawing shows:

Fig. 1 is a side view of a device according to the invention

for the transport of motor vehicles on water surfaces,

Fig. 2 the view "X" according to Fig. 1,

Fig. 3 the view "Y" according to Fig. 1.

A horizontally U-shaped, gas-fillable hose-like body 1 has a clear width that is wider than the width of a motor vehicle 2 to be transported, and its clear length is preferably longer than the wheelbase of the motor vehicle 2 to be transported. Crossbeams 3 that support the motor vehicle 2 rest on the two legs of the U-shaped, gas-fillable hose-like body 1. According to an expedient embodiment of the invention, the two legs adjoining the open side of the U-shaped, gas-fillable hose-like body 1 have a reinforced area on their upper side for better force introduction, on which the crossbeams 3 rest.

The cross members 3 have at their two ends widenings 4 adapted to the upper side of the legs of the U-shaped, gas-fillable tubular body 1, which are initially bent upwards and then adapt their bending shape to the cross section of the tubular body 1. Furthermore, the reinforcements of the U-shaped, gas-fillable tubular body 1 have elevations 5, to which recesses 6 in the widenings 4 of the cross members 3 can be assigned.

Thus, the projected surface carrying the motor vehicle 2 to be transported lies vertically between the legs of the U-shaped

tubular body 1 and the entire device is in a stable position, which is of particular importance in the loaded state.
