Description

The present invention relates to a vehicle body with a sectional door which can be moved to open and close an opening in a loading space and has a large number of panels which are pivotably mounted on one another and which can be moved on opposite sides via guide means along a guide which in the area of the opening has an im Substantially vertical section, in the upper area of the loading space a substantially horizontal section as a storage section for the sectional door and an arcuate section in between, wherein a spring shaft is provided for biasing the sectional door into an open position, with a bottom panel arranged in a closed position being pivotable is held on a running part movable along the guide, the running part having a stepped holder on which a roller is rotatably mounted, the holder fitting into an opening on a guide section of the barrel ils is inserted and the running part is fixed with a fastening section on the lower panel and can be moved with the guide section pivotably held on the fastening section via the roller on the guide.

The DE 20 2015 105 844 U1 discloses a vehicle body in which a loading space can be closed by a movable sectional door. The sectional door comprises a large number of panels which are connected to one another in an articulated manner and which are prestressed into an open position via a spring shaft. A spring break safety device is also provided on the spring shaft. When the sectional door has been moved to the open position, the bottom panel of the sectional door usually still protrudes into the opening and is located in the arcuate section of the guide. As a result, the opening height for loading and unloading the cargo area is limited by the bottom panel.

In the U.S. 2015/0 083 348 A1 discloses a sectional door with panel-shaped panels on a vehicle, in which a cable pull is fixed via a holder on an outside of the bottom panel. The bottom panel can be moved on opposite sides via a carriage on a guide, the guide having a pivotable lever so that in the raised position a lower edge of the bottom panel is arranged higher than the guide. A similar sectional door with panel-shaped panels also shows U.S. 2012/0 125 545 A1 , which forms the generic prior art.

It is therefore an object of the present invention to provide a vehicle body in which the opening height is increased and which is easy to operate.

This object is achieved with a vehicle body having the features of claim 1.

In the vehicle body according to the invention, the panels which are pivotably mounted on one another can be moved along a guide, the lower panel which is arranged on the floor in a closed position being pivotably held on a running part which can be moved along the guide. This allows the bottom panel to pivot relative to the runner, allowing the bottom panel to be raised in an open position to increase the maximum opening height for loading and unloading. As a result, the usable opening area can be increased with simple means.

According to the invention, a stepped holder is provided on the running part, on which holder a roller is rotatably mounted. The holder is inserted into an opening on the guide section of the running part and is thus mounted pivotably relative to the lower panel. As a result, the roller protrudes perpendicularly to an axis of rotation on the running part in the radial direction relative to the guide section.

Preferably, in an opening position of the sectional door, the lower panel is arranged on the arcuate portion of the guide, and the lower panel is arranged with a lower end higher than a lower end of the runner. The lower panel can thus be positioned higher in the open position, deviating from the guide.

According to the invention, the running part comprises a fastening section, which is fixed to the panel, and a guide section which is held pivotably on the fastening section and can be moved along the guide via a roller or a sliding element. The running part can thus be designed as a two-armed articulated lever which is fixed on the one hand on the panel and on the other hand can be moved along the guide. The bottom panel is preferably movable along a guide on opposite sides via such a runner.

In the vehicle body, when the sectional door is in the closed position, a lintel or a beam is preferably arranged above the sectional door, with the sectional door preferably being arranged completely behind the lintel or the beam when viewed horizontally in an open position. As a result, the maximum opening height at the hold is dictated by the bottom edge of the lintel or beam, and the sectional door may be positioned with the bottom panel higher or substantially level with the bottom of the lintel.

A tension element is preferably fixed to the lower panel, with which the sectional door can be moved into an open position via the spring shaft. As a result, the lower panel is automatically pivoted relative to the guide via the pull element, for example a cable pull, in the area of the arcuate section of the guide, without the need for additional components such as springs or drives. By pulling on the tension element, the lower panel is arranged higher than the pivotable guide section of the running part.

In a preferred embodiment, an actuating element, for example a handle or a loop, for moving the sectional door from the open position to the closed position is fixed to the lower panel. The user can then, for example, pull the sectional door down via the actuating element until the sectional door is locked in a closed position via a lock, which can also be fixed to the lower panel.

In an open position of the sectional door, a lower end of the panel can be arranged at least 5 mm, preferably between 10 mm and 50 mm, higher than a roller on the running part. In a closed position, the roller on the running part can be in an extension of the lower panel.

• 2 a view of the leadership of the sectional door on the vehicle body;
• 3 a sectional detail view of the bottom panel of the sectional door in an open position;
• 4A and 4B two views of the bottom panel of the sectional door;
• 5 an enlarged view of the running part on the lower panel, and
• 6A and 6B two views of the runner for a bottom panel.

A vehicle body 1 comprises a sectional door 2, which has a multiplicity of panels 3 which are connected to one another in an articulated manner and which, in a closed position, cover an opening in a loading space. In the closed position, a bottom panel 4 arranged on the floor is locked via a lock 5, which fixes the sectional door 2 to a floor of a vehicle.

The sectional door 2 is arranged between two posts 6, which are connected to each other in the upper area via a lintel 7 or a beam and specify the maximum opening to the loading space. The sectional door 2 can be moved from a substantially vertical closed position into a horizontal open position in which the sectional door 2 is arranged below a roof 9 .

In 2 the guide 10 for the sectional door 2 is shown, with further structural parts of the vehicle body having been omitted. On both sides of the sectional door 2 is a guide 10 having a vertical section 11 adjacent to the opening, a horizontal section for storing the sectional door 2 in an open position, and an arcuate section 13 between the vertical section 11 and the horizontal section 12. The guide 10 can be formed by individual rail sections on which guide means such as rollers or sliding elements are guided.

The sectional door 2 can be moved via a spring shaft 8 which is arranged above the sectional door 2 in the closed position and which prestresses the sectional door 2 into an open position via a tension element. The spring shaft 8 can be formed, for example, as in the DE 20 2015 105 844 U1 is described, in which a spring fracture safety device for the spring shaft is also disclosed.

In 3 the bottom panel 4 of the sectional door 2 is shown in an open position. It can be seen that the lower panel 4 does not protrude below the lintel 7 when viewed horizontally towards the lintel 7 and thus reduces the maximum opening height.

The lower panel 4 has been moved to the arcuate section 13 via a pulling element, for example a cable pull, which pulls the sectional door 2 into the open position via the spring shaft 8 . The lower panel 4 is held on the guide 10 such that it can be moved via upper rollers 15 . In the lower area, the lower panel 4 is not directly connected to the curved section 13 of the guide 10 via a roller, but via a running part 20. The running part 20 has a plate-shaped fastening section 21 which is fixed to the inside of the lower panel 4, and a pivotally or rotatably associated guide portion 22 on which a Roller 23 or a sliding element is fixed. As a result, the lower panel 4 can be pivoted relative to the guide section 22, so that a lower end of the lower panel 4 is arranged higher than a lower end on the guide section 22 or the roller 23.

Fixed to the lower panel 4 is an actuating element 14 in the form of a handle or a loop, by means of which the sectional door 2 can be moved into the closed position against the force of the spring shaft 8 . If the user pulls on the operating element 14 in a substantially vertical direction, the sectional door 2 can be moved since the bottom panel 4 is in the area of the arcuate section 13 of the guide 10 . By pulling on the actuating element 14, the lower panel 4 can be pivoted relative to the guide section 22 in order to then pull the lower panel 4 downwards from the arcuate section 13 when a stop is reached. The effort required to close the sectional door 2 can thus be kept low, and the user can also pull the bottom panel 4 essentially downwards via the actuating element 14 in the usual way.

In the 4A and 4B the bottom panel 4 is shown in detail. It can be seen that the lock 5 and a handle 16 are provided on the outside of the lower panel 4 . The actuating element 14 is fixed to an inner side of the lower panel 4 . It can also be seen that two rollers 15 are mounted on opposite sides of the lower panel 4 and mount the panel 4 directly on the guide 10 so that they can be moved. In the lower area of the lower panel 4, a roller 23 is also provided on opposite sides, which, however, is not fixed directly to the panel 4, but via a running part 20, which has a fastening section 21 fixed to the panel 4 and a guide section 22 pivoted thereto having. The roller 23 is arranged on the end of the guide section 22 facing away from an axis of rotation.

Furthermore, a cable anchor 17 is also fastened to the lower panel 4 on opposite sides, via which the lower panel 4 is connected to the spring shaft 8 via a cable pull as a tension element.

In 5 the lower panel 4 with the running part 20 is shown in detail. The attachment portion 21 is fixed to the panel 4 by a plurality of screws. It can also be seen that a stepped holder 24 is arranged on the guide section 22, one end of which is plugged into the guide section 22 and the roller 23 is rotatably mounted at the other end of the holder. The panel 4 can be raised even further relative to the roller 23 on the arcuate section 13 via the step on the holder 24 .

In the 6A and 6B the running part 20 is shown in detail. The running part 20 comprises the plate-shaped fastening section 21 and the plate-shaped guide section 22, two sleeves 26 being formed integrally with the fastening section 21 and further sleeves 27 being formed integrally with the guide section, through which an axis 28 passes. The axle 28 is longitudinally secured by an end head portion and a securing member 29 on the opposite side. As a result, a running part 20 can be produced with simple means. An opening 30 is formed on the guide section 22, into which the stepped holder 24 can be inserted, on which the roller 23 is rotatably mounted.

The lower panel 4 can also be moved along the guide 10 via other running parts, for example the rotatable guide section can be made longer or shorter. In addition, the fastening section 21 and the guide section can also be embodied in the form of an angle instead of in the form of a plate.
