Description

• – Seitenwänden,
• – mindestens einem aus horizontal verlaufenden Paneelelementen bestehenden Rolltor, welches mindestens ein dem Boden benachbartes unteres Paneelelement aufweist,
• – sowie einer Aufbauaussteifung aus biegeweichen, jedoch zugfesten, jeweils schräg bzw. diagonal verlaufenden Aussteifungselementen.

The present invention relates to a commercial vehicle body having a floor,

• - side walls,
• At least one rolling door consisting of horizontally extending panel elements, which has at least one lower panel element adjacent to the floor,
• - As well as a structural stiffening of flexible, but tensile, each obliquely or diagonally extending stiffening elements.

constructions The types under discussion here may be conventional Lorries, to trailers, on semitrailers or the like units arranged or part of the so-called Swap bodies be.

The Floors can do this as frame, grid or box constructions or combinations of these Constructions are formed.

The side walls turn can solid walls, Tarpaulin arrangements or combinations of both versions be.

The Roller shutters, depending on the application area both on the front sides as well as in the area of the side walls can be provided consist of horizontally extending, articulated interconnected Panel elements made of aluminum, steel, wood, sandwich constructions or plastic, which in the closed state vertically one above the other ordered the respective loading opening close and in the open State usually at least predominantly in the roof area horizontally under the roof skin.

building concepts Although with roller doors have the advantage of optimal access to the Loading space from a ramp on, however, have particular, though the gates are located in the front and rear of the vehicle, the disadvantage that the diagonal stiffness of the structure in contrast to superstructures with door elements is reduced. Equally reduces the side wall load capacity, as the supporting effect of the front and back end is missing.

There increasingly also in connection with roller doors, the structure for load securing is used the wall components according to common standards certain strength properties dependent on have the payload (see, for example, DIN EN 12642).

The same applies to Superstructures with double-deck function. Due to the high side wall load be particularly high demands on the shear stiffness of the front and back wall posed. As replacement for a shear-resistant front or rear wall element are stiffening elements in the form of pre-stretched straps, ropes or corresponding elements which bend soft on one side, On the other hand, however, are designed to accommodate high tensile forces used.

A commercial vehicle structure of the generic type is for example from the DE 94 13 332 U1 known.

According to one embodiment This known construction is the stiffening of the structure at an angle or diagonal ropes or the like, each with their lower ends at fixed attachment points on the ground and with their upper ends to frame-fixed points of the structure on the side walls are fixed. This should especially with truck bodies with Double-deck function despite front-side roller door, in particular on rolltorseitigen end sufficient rigidity against the front be achieved by all applied by the charge shear forces.

task The present invention is to provide a commercial vehicle structure of generic type too improve and in particular ensure that even at high static and dynamic load and long-term use the strength properties of the closed structure and damage to the Rolltores is avoided.

• – dass das untere Paneelelement des Rolltores über eine Verriegelungsanordnung lösbar und kraftaufnehmend an den Boden ankoppelbar ist, und
• – dass mindestens zwei, jeweils schräg und in entgegengesetzten Richtungen über das Rolltor verlaufende Aussteifungselemente vorgesehen sind, die jeweils mit ihrem einen Ende an dem unteren Paneelelement des Rolltores kraftaufnehmend befestigt sind.

This object is achieved by the invention

• - That the lower panel element of the roll-up door via a locking arrangement releasably and force-absorbing is coupled to the ground, and
• - That at least two, each extending obliquely and in opposite directions over the roller door stiffening elements are provided, which are each mounted with one end to the lower panel member of the roller door force-receiving.

The invention is based on the idea to provide the elements provided for the stiffening not as usual in the prior art exclusively on the structure, but at least partially directly and directly attack on the roller shutter itself and thus to create a stable unit, so that a portal element with high diagonal stiffness is formed, whose strength is also on the neighbors stiffening part of the structure and stabilizing effect.

One An essential element is that the lower panel element on the Locking arrangement in the locked state a statically highly effective Unit with the bottom of the construction forms, beyond which even after a long time Operating time safe and reliable over the Stiffening elements forces can be initiated.

The Locking arrangement can be designed in a variety of ways and be arranged. So can for example, claws, hooks or slides as locking elements be provided. The locking elements can be centered, in pairs spaced from the center or in the area of the panel ends be. The most built-up parts of the locking elements can in Ground recessed, provided on the side of the sill or in the corner pillars be.

The each at an angle and extending in opposite directions across the roller door Bracing elements can with their other, i. the lower panel element of the roll-up door opposite end in different ways absorbing force be attached.

So Is it possible, the stiffening elements with their other end to an upper Panel element of the roll-up door to absorb force.

at Commercial vehicle superstructures with columns, for example, corner posts However, on both sides of the roller door, it is also possible, the Stiffening elements with their other end respectively on the columns themselves, preferably to be fixed in the roof area.

at Rolltorkonstruktionen where the stiffening elements with their other end are attached to the upper panel element of the roll-up door, it is advantageous, the upper panel element in the region of its two Equip each end with a coupling element, which force receiving connectable to the adjacent column.

This Coupling element can according to the particular circumstances be designed differently. In a preferred embodiment the coupling element is in each case connected to the panel element Coupling provided in a bolt attached to the column Holder engages. Preferably, the holder is a U-shaped backdrop designed in which a mushroom-shaped head engages the coupling pin when closing the roller shutter.

Of the Course of the stiffening elements can be V-shaped, X-shaped, W-shaped or a combination of these Be arrangements. It is only essential that the desired diagonal stiffness achieved and the bottom attachment as close as possible in the area the locking arrangement takes place.

The Bracing elements can on the Rolltorinnen- or on the Rolltorau outside. In special cases can Also, a combination of both arrangements are provided.

ever at the option of the stiffening elements (cable arrangement, belt arrangement or the like) the attachment points be designed differently. Advantageous it is in any case when the mounting arrangements of Pull direction automatically can adjust.

tries have shown that with appropriate design no restrictions in relation to the so-called "handling" of the roll-up door in Purchase must be taken. Rather, the arrangement according to the invention the considerable advantage that the stiffening elements are not in a separate step must be attached or stretched. While at the known arrangements of the prior art roller door and Bracing elements to be operated separately, be in the inventive solution when opening the Rolltores automatically release the stiffener and when Shut down the roller door again tense. It is advantageous when using straps elastic traction means or the like means the stiffening elements when opening the Rolling doors moved out of the area of the clear cross section of the door opening and the stiffening elements automatically when closing the roller shutter again be placed in position.

One Another advantage of the solution according to the invention is that conventional Rolltorkonstruktionen at a later date without intervention be easily retrofitted into the overall structure of the structure can.

Equipped according to the invention Roller shutters are easy to open and close by hand. Pneumatic or electrically powered roller doors can also be equipped according to the invention.

in the Prior art, no roller door designs are known so far, having a component strength to meet requirements, such as she for the Load securing are required (see, for example, DIN EN 12642).

In order to achieve this component strength, it is advantageous in the context of the invention to increase the bending stiffness of the panel elements by means of corresponding profiles, which are preferably mounted on the inside of the panel elements. By This measure achieves the required component stiffness and ensures that the structure as a whole meets the requirements of load securing.

in the The following are for further explanation and for better understanding the invention two embodiments with reference to the attached Drawings closer described and explained.
