Description

The invention relates to a box body for vehicles according to the preamble of claim 1.

Box bodies in the sense of the invention are closed bodies with a loading opening. The loading opening can be closed by a pivoting tailgate. Box bodies of this type are also referred to as box bodies. The box bodies according to the invention are used in vehicles of all types, for example in tractors and in trailers without their own drive.

Known box bodies have a floor wall and a tailgate that can be pivoted around a pivot point to close the loading opening. To load or unload the box body, the tailgate is pivoted downwards around the pivot point in the direction of

The tailgate is swiveled towards the vehicle's lane or towards a road surface. In this case, the tailgate serves as a loading ramp. Since the maximum length or height of the tailgate corresponds to the height of the loading opening, loading ramps with a steep angle of inclination are created in known box bodies after the tailgate is swiveled. However, a steep angle of inclination is disadvantageous for loading the box body.

&iacgr;&ogr; Based on this, the present invention is based on the problem of creating a box body for vehicles which can be easily loaded overall.

To solve this problem, the box body according to the invention has the features of claim 1. Because the pivot point is lowered relative to the essentially horizontal floor wall of the box body, the tailgate can be designed to be correspondingly longer. Overall, this ensures that after the tailgate has been pivoted, a loading ramp is provided which has a small angle of inclination. In this respect, the box body according to the invention can be easily loaded.

Preferred developments of the invention emerge from the subclaims and the description. An embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows:

Fig. 1 a transporter with the inventive
Box body in side view, and

Fig. 2 shows an enlarged detail of the box structure according to the invention in the area of a pivot point of a tailgate.

Fig. 1 shows a transporter 10, wheels 11 of the transporter 10 and a road surface 12. Behind a passenger compartment 13 of the transporter 10, the same has a box body 14.

The box body 14 has a cuboid-shaped structure with a floor wall 15, top wall 16, front wall 17 and side walls 18. On the side of the box body 14 opposite the front wall 17, the same is open and therefore has a loading opening 19. The loading opening 19 extends over the entire area of a rear surface of the transporter 10. The loading opening 19 can be closed by a pivoting tailgate 20.

&iacgr;&ogr; The cuboid-shaped, closed box structure 14 therefore encloses a transport space or loading space of the transporter 10. The bottom wall 15 of the box structure 14 serves as a loading area.

Below the floor wall 15, the box structure 14 is reinforced or stabilized by a support 25. The box structure 14 is connected to a frame 26 of the transporter 10 via this.

To load or unload the transporter 3.0 or the box body 14, the tailgate 20 is pivoted downwards towards the road surface 12. For this purpose, the tailgate 20 is mounted on the box body 14 so that it can pivot about a pivot point 21. As a result of the pivoting movement of the tailgate 20 about the pivot point 21, one end 22 of the tailgate 20 comes to rest on the road surface 21. In this case, the loading opening 19 is open for loading or unloading the box body 14. The tailgate 20 pivoted onto the road surface 12 forms a loading ramp.

so To pivot the tailgate 20 about the pivot point 21, the same actuating elements 23 are assigned. The actuating elements 23 are preferably designed as gas pressure springs.

In order that the tailgate 20 pivoted towards the road surface 12 forms a loading ramp with the smallest possible angle of inclination for loading or unloading the box body, according to the invention the pivot point 21 of the tailgate 20 is lowered downwards relative to the essentially horizontally extending bottom wall 15 of the box body 14. Furthermore, the

« i

The tailgate 20 is extended by the amount of the lowering of the pivot point 21 relative to the floor wall 15. Two effects therefore overlap: By lowering the pivot point 21, the tailgate 20 must be pivoted by a smaller amount to load or unload the box body 14. This effect is reinforced by the extension of the tailgate 20. Due to these two advantages, the tailgate 20 forms a loading ramp with a small angle of inclination when pivoted.

&iacgr;&ogr; The pivot point 21 is lowered relative to the bottom wall 15 of the box structure 14 in such a way that an end region 24 of the bottom wall 15 has an inclined profile. The inclination of the end region 24 is adapted to the inclination of the tailgate 20 pivoted towards a loading ramp. In an open loading position of the tailgate 20, the inclination of the same is therefore adapted to the inclination of the end region 24 of the bottom wall 15. These inclinations are preferably approximately the same.

Although the bottom wall 15 of the box body 14 has an inclined profile in the end region 24, this generally does not result in any loss of loading space in the box body 14. The inclined end region 24 of the bottom wall 15 is not a disadvantage for objects delivered on pallets and to be stowed in the box body 14 according to the invention. In this case, the pallet stabilizes the load. The inclined end region 24 of the bottom wall 15 also does not have a disadvantageous effect when loading the box body 14 with trolleys, since the rollers of such trolleys are not attached directly to the lateral end regions of the same, but are generally installed inside the trolleys.

In the embodiment shown, the dimensions of the tailgate 20 are adapted to the dimensions of the loading opening 19. In the closed state, the loading opening 19 is therefore completely closed by the tailgate 20. This means that the tailgate 20 has a greater height or length than the front wall 17 of the box body 14. The difference between the two dimensions corresponds to the amount of lowering of the pivot point 21 compared to the horizontally running floor wall 15.

In deviation from this, it is also possible that the tailgate 20 is not adapted to the dimensions of the loading opening 19. It is thus possible that the tailgate 20 has a smaller length or height than the loading opening 19 of the box body 14. In this case, the loading opening 19 is not closed over the entire height, but a gap is formed between the end 22 of the tailgate 20 and the upper wall 16 of the box body 14. It is also possible that the tailgate 20

&iacgr;&ogr; has a greater height or length than the loading opening 19 of the box body 14. So that the tailgate 20 does not protrude beyond the upper wall 16 of the box body 14 in this case, the tailgate 20 can be folded up in one end region thereof. An end section of the tailgate (not shown)

The flap 20 can then be pivoted by 180° and thus shorten the tailgate 20 when closing the loading opening 19. For loading and unloading the box body 14 and for forming the loading ramp, however, the pivotable end section of the tailgate 20 is folded over to extend it.

The box body according to the invention shown can be used both in tractors with their own drive and in trailers without their own drive.
