Description

The The invention relates to a cover device for an open-topped loading structure a vehicle, such as trucks, truck trailers, or the like, according to the preamble of claim 1.

at an open-top loading structure, especially for bulk bulk, such as granular industrial goods, such as Sands and minerals or agricultural commodities, such as cereals, fruits, too crushed or for Scrap and other goods, which are loaded from above, the cover of the cargo space takes place with a tarpaulin, the side of a longitudinal upper edge of the loading structure is moored and to cover over the opening of the loading structure, in the at least two removable crossbars are attached, pulled is going to erosion by air flow and to prevent moisture from entering the cargo.

It But they are often formed Watering in the tarpaulin, whose weight is removing rainwater, Making snow or ice very difficult or impossible by hand and that will then be omitted while it avoids dangers for the traffic often would be indispensable and also to protect moisture-sensitive cargo is necessary.

It is known lifting devices for to provide the tarpaulin shell of a vehicle for congestion from rain water drain can and Auflagernder snow or ice are blasted off and slip off.

such Devices are not in such, open-top loading structures to install, because only two or three or scattered crossbeams be used, which must be built, because otherwise the tarpaulin assembly take unreasonably long and moreover would make the construction much more expensive. This leads to the formation of extensive water retention which are difficult to remove.

task The invention is a covering device for the loading structure of a vehicle, truck or truck trailer s, to be provided with a lifting device with which it is possible to eliminate the disadvantage described and the stretched tarpaulin so far raise that the outflow angle for water and the slip angle for snow and Ice far exceeded will that no Remains on the tarpaulin can remain. moreover the device should be operable with a remote control by the driver be and it should be possible be, this lifting device also subsequently in roll tarpaulins of loading structures of vehicles with an open charging structure.

These Task is in a covering for a loading structure of a vehicle solved with the features of the characterizing part of claim 1.

The Under claims, which at the same time form part of the description of the invention, relate to particularly advantageous embodiments of the invention.

at a covering device for the open-top loading structure of a truck s, truck trailer, or the like, with a tarpaulin, which at one of the longitudinal upper edges of an open Loading structure attached and wound up to a roll is mounted to close the tarpaulin up over the opposing along the top edge of the loading structure with the help of a tensioned tension bar pulled, the then tensioned with tension cables.

to Removal of water, snow or ice filled hollows or beads in The tarpaulin, which is very difficult to dispose of, becomes a lifting device for the Rollplane attached to give the tarpaulin a shape when no Recesses arise or these are caused by the resulting tension the tarpaulin removed.

That's because of the design and operation of the Rollplane the lifting device flexible and limp and trained in the working condition stiffened, wherein to prevent sagging of the lifting device the attachment of a rigid supporting longitudinal member is used, on which the lifting device mounted on at least one front and one rear Crossbar rests and is rolled up together with the tarpaulin or when the roll-up over the opening of the load structure is pulled, this stiffening stiffened, with what even lifting the tarpaulin is ensured.

For a sufficient Raising the tarpaulin is the attachment of a flexible limp Lifting device, arranged approximately in the middle under the tarpaulin, sufficient.

A especially simple cheap Design becomes with the use of at least one air hose made of plastic or rubber, which fold flat and let it roll up with the tarpaulin, closed on all sides is and to support Lift with a compressor to inflate and stiffen and for the merging with the free air for emptying is connectable.

A favorable design of the air hose is the production of a film tube which is closed at the two ends and is provided with end tabs, in the conveniently several eyelets are used by both sides each an elastic band is led to exciting attachment.

to Avoid sagging the inflated and thus stiffened air hose is the use a stiff load-bearing side member of Advantage on which the air hose rests and is supported when the position of the air tube is fixed by at intervals the underside flaps are attached, through which straps are pulled, with which the air hose is fastened.

simplistically for the Assembly and disassembly is when the stiff side member, together with the roll tarpaulin and the at least one air hose, as flexible pliable lifting device, several of which provided could be, with open loading structure, rolled up together to a roll or when mounting over the opening of the loading structure is pulled and with, in the end of the roll tarpaulin preferably worn tension bar held by the tensioning cable is curious.

For the required Stiffness and easy resistance to rolling is the Use of a side member with correspondingly adapted profile advantageous. This one can be from one Pipe, a forming tube, a beam, a lattice girder or be made of the same.

Of the Air hose has a circular cross-section in inflated working condition up and over with a height Inflatable upper edges of the loading structure, in which the inclination of the Rollplane the drain angle for water and the slip angle for Snow and ice are passing and is with a hose connection for an air hose line provided for connection to a compressor.

To the Inflating and deflating the air of the air hose this is over a Air hose line with a three-way valve and over this either over a connecting line with a pressure reducing valve and continue with the compressor for inflation or with the free air for emptying connected.

to Fixing the position of the air hose and the roller tarp to each other is it cheap at the top. of the air tube to the opposite Make the detachable Fixing a strip of a detachable Lanyard, such as Velcro strips or double-sided adhesive strips to install. It is characterized by a lateral deflection of the air hose especially during of inflation avoided.

For the quick activity the lifting device is provided with a remote control device, with the compressor and / or the three-way valve to inflate or Emptying the air are controllable.

The The invention will be described with reference to the drawing of an embodiment.

It shows:

1 a truck loading structure with upper opening, in an oblique view, partially removed the tarpaulin, schematically;

2 a view of the underside of the air tube, schematically;

3 a cross section through the lifting device with air hose, attachment bottom and top and partially raised roll tarpaulin, schematically;

4 a Anordngsgschema for a lifting device with the means for their operation.

In 1 is shown a vehicle body whose bottom 7 not shown front and rear wall and the side walls 6 limits a charging structure 3 forms, with upward opening 5 ,

The opening is from a roll-up tarpaulin 1 Covered as covering, which at the first longitudinal upper edge 9 the side wall 6 is attached and over the other longitudinal top edge 11 extends down and at the end of a Spannstatte 12 running in, which is approximately horizontal on the other side wall 6 is arranged and from a tensioning rope 23 pulled down is stretched.

Under the roll-up tarpaulin 1 is an air hose 2 longitudinal 10 the loading structure 3 aligned, mounted on a Länggsträger 13 rests, in turn, on at least two removable crossbar 4 is up.

Out 2 can be seen how to guide and hold the air hose 2 at the bottom at intervals tabs 8th are attached, through the straps 14 which are drawn around the side member 13 are guided around for attachment.

In 3 it can be seen that the air hose 2 in partially inflated state has a depressed cross-section on which the tarpaulin 1 rests. Here are at the top of the roll tarpaulin 1 and on the opposite inner side of the roll-up tarpaulin 1 , preferably at intervals, detachable Adhesive, such as Velcro strip or the like, attached, whereby the air hose is held in a central position.

In 4 is a layout scheme for the air hose 2 with the hose connection 17 for the air hose line 18 and a three-way valve 21 that with a compressor 20 or connected with the outside air.

From the three-way valve 21 leads a connecting line to a pressure reducing valve 22 for the slight overdoing of Zentel-Bar and on to the compressor 20 ,

For inflating the air hose 2 becomes the reduced air pressure of the compressor 20 through the air hose line 18 in the air hose 2 passed while opening the three-way valve 21 is shut off to the open air.

When emptying the air hose 2 becomes the air hose line 18 over the three-way valve 21 open to the open air and the connection line 19 locked to the compressor.

The Control of compressor and three-way valve can not with one shown control device from the cab of a truck done.
