Description

The invention relates to a tarpaulin structure of a commercial vehicle. Such a tarpaulin structure defines a cargo space in which the goods to be transported is stored, and has a support frame with two guide rails, which extend along the sides of the tarpaulin structure. In each case, a guide rail is assigned to one of the long sides of the tarpaulin structure. At the same time, the tarpaulin structure has a roof that includes a roof tarpaulin and the roof tarpaulin supporting roof bows and a carriage, which is slidably supported on the guide rails in the longitudinal direction. The roof bows are aligned axially parallel to each other and slidably mounted with their ends on the guide rails in the longitudinal direction for opening and closing the tarpaulin structure.

Such a tarpaulin structure is described, for example, in the operating manual "tarpaulin trailer", which has been issued by the applicant and the no. BA 919316, printing notice 11/05, received.

Commercial vehicles of the type in question here are typically conventional trucks, trailers for such trucks or semi-trailers pulled by a tractor, also referred to in the jargon as "trailers".

The structures provided on such commercial vehicles define a loading space and protect the goods transported therein against external influences. Tarpaulin structures are usually designed so that they shield the cargo against dust, moisture and the like. For this purpose, used in practice tarpaulin assemblies typically have a fixed, seen in the normal direction of travel front end wall and a rear wall, which also consists of solid elements and usually includes a double-leaf door, via the loading of the cargo space from the back can be done.

By contrast, the longitudinal sides and the roof of commercial vehicle tarpaulin constructions usually consist of one or more tarpaulins, of which the longitudinal side tarpaulins can usually be displaced in the direction of the front or rear side of the vehicle in order to also allow the loading space to be loaded from the respective longitudinal side , In the same way, the roof tarpaulin forming the roof tarpaulin is usually displaceable in the longitudinal direction of the tarpaulin structure in order to be able to open it and to allow loading from above. During postponement, the roof tarpaulin typically remains firmly hinged to the front or rear wall of the structure, while it can be pushed from the other side toward the wall in question. The longitudinal sides of the roof tarpaulin are guided during the sliding and closing on the supporting them roof skirts to the guide rails of the support frame of the tarpaulin structure.

The carriage fulfills several functions in tarpaulin structures with such sliding roof tarpaulins. With the roof closed, on the one hand, it forms the roof of the roof on the side of the roof tarpaulin, from which the roof tarp is slid to open the roof. On the other hand, it serves as a force application point for the usually open and close manually applied shear or tensile forces, thereby ensuring that these forces are transmitted evenly to the roof tarpaulin. This ensures that the roof tarpaulin when pushed into regular folds, which form a compact package with fully open roof tarpaulin. Furthermore, the carriage usually carries a locking mechanism, via which the roof is locked when the cover is completely closed.

To ensure optimum tightness, the carriage usually carries a cover plate, which extends over the width and a short part of the length of the roof and over which the roof tarpaulin is connected to the carriage. Usually, a vertically projecting from it downwardly projecting portion of this cover plate, which engages over the edge of the front or rear side with the roof closed, abuts the carriage when the roof is closed. In order to still allow easy opening of the roof, provided with the protruding portion cover plate is designed as a flap which along a paraxial to the roof bows of the roof extending pivot axis away from the support frame of the tarpaulin structure and can be swung back to the support frame. The swivel angle is dimensioned such that, when the flap is fully swung open, there is sufficient clearance between the underside of the protruding section and the support frame, and the guide carriage can be moved into the open position without the risk of a collision.

Due to their diverse function and the high forces that they have to absorb under harsh operating conditions, the carriages in tarpaulin structures of the type in question are particularly robust. This robust construction brings a high weight and a comparatively high assembly costs with correspondingly high production costs.

Against this background, the task has been found to create a tarpaulin structure with a carriage, which are produced inexpensively while safely withstanding the stresses occurring in practice.

The invention has achieved this object by the plan structure specified in claim 1.

Advantageous embodiments of the invention are set forth in the dependent claims and are explained below, as the general inventive concept in detail.

An inventive tarpaulin structure of a commercial vehicle thus defines in accordance with the prior art described a cargo space and has a support frame with two guide rails, which extend along the sides of the tarpaulin structure, wherein each guide rail is associated with one of the long sides of the tarpaulin structure and wherein the Tarpaulin a roof that a roof tarpaulin and the roof tarpaulin supporting roof bows, which are aligned axially parallel to each other and are slidably mounted with their ends on the guide rails in the longitudinal direction for opening and closing the tarpaulin structure, as well as a guide carriage, which also on the guide rails in the Is longitudinally displaceably supported, wherein the guide carriage with closed roof of the roof closes the roof of the roof at its one end of the guide rails associated end.

According to the invention, in such a tarpaulin structure, the guide carriage now comprises a base structure which is formed by at least two of the roof hoops mounted on the guide rails, which are coupled to one another by at least one coupling element.

Thus, according to the invention, two roof skirts which are present anyway in a tarpaulin structure according to the invention are used to form a basic structure on which the remaining elements of the guide carriage are constructed. The invention makes use of the fact that roof hoops are produced in large quantities as standard components and are optimized with respect to the leadership of the roof tarpaulin on the guide rails of the tarpaulin structure. It has surprisingly been found that it requires no special reinforcement or other redesign of the roof hoop in order to use it for a designed according to the invention guide carriage. Rather, it is sufficient to couple two of the roof bows by a coupling member together so that the roof bows are held at a defined distance and thus form a platform, which are slidably mounted at the ends of the roof bows guides provided on the respective guide rail. In a tarpaulin structure according to the invention the guide carriage is therefore supported per guide rail via at least two guides, whereby a safe and tilt-free run of the carriage is also secured when the forces required to open or close the roof with respect to the longitudinal extent of the roof off-center on the car be applied. Of course, more than two roof bows can be combined to the basic structure of the carriage, for example, if it turns out that two brackets are not sufficient to absorb the forces acting on the carriage or the load of the other components of the carriage. It is crucial that the roof bows used for the base of the carriage be their basic constitution according to each identical with the other agreed to support the roof tarpaulin roof mating match.

Due to the inventive design of the carriage on the basis of standard components, namely the roof bows, not only eliminates the need for special designs for the guidance, storage and support of the carriage, but it results in addition to the cost savings achieved in this way, a particularly lightweight design, with It is particularly easy to open and close the roof of the roof.

The coupling of the base of the carriage forming the roof hoop can be done in any suitable manner, which is the force acting on the carriage cars forces. Conceivable are articulated or rigid connections. The coupling of the roof hoop should be done so that a tilt-free running of the basic structure of the carriage on the guide rails is guaranteed at all times.

This can be ensured for example by the fact that the base of the carriage receives a ladder structure by the coupling member is aligned axially parallel to the guide rails and thus orthogonal to the axial direction of the roof bows.

A stability of the basic structure of the guide carriage which is sufficient at all times can be achieved in that the basic structure comprises at least two coupling links, one of which is arranged adjacent to one of the guide rails.

As already mentioned, the respective coupling members can be articulated or fixedly connected to the roof hoops of the basic structure of the guide carriage. A hinged connection may possibly be useful if it turns out that a certain play of the combined to the basic structure roof bows is required as a result of manufacturing tolerances to a avoid tilt-free run of the carriage. In most applications, however, it makes sense to firmly perform the coupling, so that the roof bows are permanently held in a fixed distance and optimally aligned parallel to each other.

As with the prior art described above, even with a tarpaulin structure according to the invention the base structure of the carriage carry a flap which extends at least over the limited by the guide rails width of the roof panel and is mounted about an axis parallel to the roof spoons aligned pivot axis pivotally mounted on the carriage. This flap can also be pivoted to open the canopy from a closed position in which it is pivoted to the guide rails in an open position in which it is pivoted away from the guide rails. In order to assist the opening of the flap, at least one spring element can be provided in a manner which is likewise known per se, which resiliently loads the flap resiliently with a pivoting moment directed in the direction of the open position. The spring element can be designed so that the flap is automatically held by the spring force exerted by him in the open position.

The pivotability of the flap proves to be particularly useful if, as known from the prior art, the flap a first portion which is pivoted in befindlichem in the closed position flap to the base structure of the carriage, and a second section has, which protrudes angularly from the first portion, so that the second portion is pivoted in the closed position flap to a side surface of the tarpaulin structure.

The storage of the roof hoop of a tarpaulin structure according to the invention can be done in any suitable manner. With regard to the inventive use of the roof hoop as the basis for the carriage, however, it proves to be particularly advantageous if the roof hoop are mounted resting on the guide rails. If the roof bow thereby have end pieces with which they laterally surround the guide rails on their side remote from the load compartment outside and over which the roof bows are guided displaceably on the outer sides of the guide rails, then there is an exact storage, which is a slight displacement of the guide carriage and with him the canopy between the closed and the open position allows.

In order to prevent that the tarpaulin is clamped in the region of its connection to the flap of the carriage when pushing or closing the tarpaulin, it may be expedient if the distance between the respective one of the guide rails associated end pieces of the guide carriage associated roof bow bridged by an apron is. This mudguard may for example consist of a metal material or a suitable plastic.

The invention will be explained in more detail with reference to a drawing showing an embodiment. Their figures show each schematically:
