The invention relates to a device for straightening a body of a vehicle in the form of a substantially vertical aligned straightening column in its lower end area has a base with which the straightening column on a Footprint of a stationary surface or a mobile one Straightening bench can be set up and used to determine your working position with one or more fasteners recessed in the base, L- and / or C-shaped Rail elements is fixedly connectable.

For straightening bodies, especially those damaged by accidents Devices are required with which vehicles the vehicle can be brought back to its original shape can. For this purpose, these devices are designed such that these are attached to the deformed vehicle parts can to this by applying pressure or tensile forces to be able to deform the corresponding vehicle part. This will the vehicle is usually stationary on a mobile bench mounted, which in turn fixed to the surface is anchored. This straightening bench has one or more L- and / or C-shaped rail elements, which around the on the Straightening bench and fixed vehicle around are arranged. A straightening column can be used with these rail elements connected to her stand on the bench be attached so that appropriate on the straightening column Pulling and / or pushing devices deform the vehicle or can be directed. This means that with a bench, which is provided with such rail elements, the straightening bench even a stand for the leveling column to be set up forms.

With stationary or fixed so-called straightening frames are the rail elements in the underground itself in the surrounding area the bench straightened so that this surface forms the footprint for the straightening column. To use a vehicle such a stationary straightening frame or a mobile one Align the bench correctly on every conceivable side of the vehicle To be able to, it is necessary that such a device simple and handy according to the respective requirements can be adjusted. This means that to judge one Vehicle often moves to a new location must be converted to include all deformed vehicle parts achieve as optimally as possible with the pulling and / or pushing devices to be able to.

EP 0 090 700 B1 describes a device of the generic type Known way of straightening the bodies of vehicles, which is a substantially vertically oriented straightening column has, which can be moved on the base on a base is. Around the straightening column in its respective working position to fix, one or more restraint chains are provided, over which the straightening column is anchored to the underground can by pulling the chains with those embedded in the underground Rail elements are engaged. As a tension element is a hydraulic or inside the straightening column pneumatic pull cylinder provided on which a pull chain is fixed inside the straightening column. The train chain is after led out of the straightening columns at the top and via one at the top Deflection roller arranged on the outside along the end of the straightening column the directional column deflected downwards. On the outer circumference of the A second pulley is provided over the straightening column the pull chain is deflected towards the vehicle. This second pulley can be adjusted in height using a fastening collar be attached to the straightening column. The free end the pull chain is connected to the part of the vehicle to be straightened. If the pull cylinder is now activated, the pull chain becomes the straightening column is pulled in, due to the double deflection the pull chain on the vehicle or on the one to be aimed Vehicle part exerted a tractive force and this in its original Shape is deformed back. To absorb the tensile forces is the pull cylinder in the area of the lower end of the Alignment column articulated. Through this articulated attachment the pull cylinder becomes an automatic straight line alignment of the pull cylinder in operation to the pull chain inside reached the straightening column, so that it is as optimal as possible Power flow results. When the pulling force is exerted, the base becomes the known device also axially loaded. The casters on which the stand can be moved in the unloaded state is elastic on the base. Due to the axial load when the pulling cylinder is activated, the elastic support the castors so that the base is fixed against the surface is pressed.

This known device has the considerable disadvantage afflicted with that of the one inside the vertical Column arranged hydraulically or pneumatically Pistons actuated the pull chain optimally only certain body parts can be reached and directed so that for others Body leveling tasks other suitable leveling devices must be used, which is inefficient and uneconomical is. Furthermore, known by this Device only pulls on the vehicle body to be aimed are exercised so that further device is provided need to be able to apply pressure forces. Also receives the straightening column with its base only with larger operating forces their required stable hold by the Interaction of the pulling force in the pull chain and the resulting one resulting reaction forces in the restraint chains. This means that the entire system is extremely unstable and only can be used safely under optimal conditions.

Another device of the generic type is known from EP 0 353 865 A1 Type for straightening damaged bodies known from vehicles. This device is also a straightening column is provided, which is also a pedestal having. The stand is in this known device provided with a base plate with which this just on the Underground, e.g. in the area of a straightening frame with his Rail elements can be set up. So that becomes a Relatively stable, vertical alignment even when unloaded reached the straightening column. This must also be in operation Straightening column through one or more restraint chains in the underground recessed rail elements of the straightening frame or connected to the bench and braced. In the area of Stand is a pneumatic or hydraulic pressure cylinder provided by activating a in the area of Base plate swivel-mounted swivel lever swiveled becomes. A pull chain is articulated at the free end of the swivel lever, which leads to a fixed deflection roller of the straightening column leads. Through this deflection roller, the pull chain is closed upwards a second adjustable in height on the straightening column Deflected pulley. The second pulley will Pull chain redirected to the vehicle to be straightened and is with its free end connected to the vehicle to be straightened. If the pressure cylinder is activated, the swivel lever a corresponding tensile force exerted on the pull chain, whereby this traction via the pulleys through the pull chain acts on the vehicle part to be straightened.
