Tarpaulin structure

A tarpaulin structure for a substructure, such as one of a heavy goods vehicle, a trailer, a semitrailer, a railway carriage, a tipper truck and a container, comprising:

• a top frame;
• and
• a tarpaulin composed of weather-resistant material,
• wherein the top frame has a multiplicity of beams which have, on the ends, in each case a carriage which is displaceable along a guide,
• wherein at least one bow is pivotally attached to each pair of oppositely situated carriages,
• wherein the at least one bow forms a tarpaulin folding aid together with a facing bow of an adjacent carriage pair,
• wherein the bows of the tarpaulin folding aid are connected to one another,
• wherein a covering bow is pivotally attached to the foremost carriage pair,
• wherein, during displacement of the foremost carriage pair, the covering bow is pivotable, by way of a run-on bevel of the guide, from a lowered closing position into a partially raised movement position, and
• wherein the covering bow is, close to a fully opened position of the tarpaulin structure, pivotable from the partially raised movement position, using a stop member positioned at a rear end of the guide, into an upright opening position.

A tarpaulin structure for a substructure, such as a heavy goods vehicle, trailer, semitrailer, railway carriage, tipper truck or container, comprising:

• a top frame;
• and
• a tarpaulin of weather-resistant material,
• wherein the top frame has a multiplicity of U-shaped beams which have, on the ends, in each case a carriage which is displaceable along a guide,
• wherein at least one U-shaped pivot bow is pivotally attached to each pair of oppositely situated carriages,
• wherein said at least one pivot bow forms, together with a pivot bow of an adjacent carriage pair, a tarpaulin folding aid,
• wherein the pivot bows of the tarpaulin folding aid are connected to one another using a connecting member,
• wherein the pivot bow attached to the pair of foremost carriages transmits a pulling movement from one foremost carriage to the oppositely situated foremost carriage, and
• wherein the pivot bow attached to the pair of foremost carriages and being part of the foremost tarpaulin folding aid is loaded in a direction counter to the lifting of the tarpaulin with an increased load with respect to any other pivot bow of any other tarpaulin folding aid, ensuring as long as possible an introduction of force in the direction of the guide avoiding a premature lifting of said pivot bows such that the movable parts of the top frame fold together from rear to front.
