    Sales car
    The invention relates to a sales trolley, with a case-like structure which has vertically supported supports and a roof element fixed thereto, on which at least on one longitudinal side one or a plurality of side walls are pivotally supported such that each side wall from a vertical position to enlarge the roof surface is pivotable in a pivoted position, wherein at least one linear drive is added to each side wall which is coupled with an end to a stationary axis remote from the roof element, and the opposite end of which is on the side wall remote from the edge added to the roof element is struck.
    Such a sales car is disclosed in DE-298.112.148U1.
    The present sales car can be a self-driving vehicle or a trailer. In the driving position, the side walls are pivoted inwards, that is, they are vertical. In the sales position, the side walls are pivoted from one side or from both sides in order to increase the buyer surface. The rear wall is also usually pivoted. In order for a quadrangular roof surface to be formed, roof corner parts are also arranged on the side walls which lie in the sales position in the corner areas of the entire roof surface. In so far as it concerns a sales trailer, the head plate facing the drawbar is also usually pivoted. The securing of the side walls, the roof corner parts, the tailgate and optionally the head plate, takes place by at least one straight-line drive, but usually by two straight-line drives that are added to the two edge areas. Gas springs are preferably used as linear drives. The gas springs, or the linear drives, respectively, are designed in such a way that the construction parts that increase the roof surface area can be swiveled out either automatically or with a small amount of effort. The swiveled position is fixed by the gas springs or by the linear drives.
    Such designs have been satisfactory in practice. However, it is found to be a disadvantage that when pivoting inwards and outwards, the structural components which increase the roof surface in the vertical or in the pivoted position must be applied at the start of the manual pivoting operation, which force must be clearly increased through a subsequent angular range. Each gas spring is fixed with one end to a vertical support and with the other end to the structural component that enlarges the roof surface at a relatively short distance from the fixed roof surface, so that the gas springs do not protrude too far into the movement space of the people visiting the sales car.
    In CH-0.393.134A, a device is disclosed for opening and closing a door leaf. This device comprises a linear drive that consists of a cylinder and a drive piston. A lever is coupled to the drive piston and acts as a lever with an arm and is supported around a fixed pin. The pivoting movement is achieved by the loaded drive piston. A second lever is coupled to this lever and is hinged to a strip via a pin. A hinge triangle is formed by this kinematic arrangement, so that the torques can be changed during the closing movement for driving the door leaf.
    The transfer of the door leaf into the closed position takes place by means of a closing spring which is secured to the lever with an arm at the end opposite the fixed pin via a spring strip.
    This arrangement is difficult, which is determined by the cylinder with the drive piston, the closing spring and the hinge triangle.
    It is an object of the invention to design a sales car of the above-mentioned type in such a way that swiveling inwards and outwards of the structural parts which increase the roof surface, for example the side walls, the roof corner parts, the tailgate and the head plate, facilitating the covering of a certain angle is facilitated. reduces the effort required then relative to known assemblies.
    This object is achieved in that the linear drive is coupled at one end to a coupling element that can be rotated automatically about a fixed axis, that the coupling element can pivot about a pin which extends transversely to the plane of the side surface enlarging surface of the roof surface and which remote drive of this tap is coupled to the coupling element such that the distance from the free end of the linear drive to the edge added to the roof element in the pivoted position of the side wall is greater than in the vertical position.
    The distance to the pivot axis of the construction component in question is reduced if a certain angle is covered when pivoting this construction component inwards. By reducing the effective lever arm, the effort is thereby reduced. The outward swinging of the relevant component takes place by supporting the linear drive or the gas spring, respectively. The coupling element is designed such that the pivoting movement thereof takes place automatically. When pivoting outwards, the coupling element is rotated in the opposite direction, so that the distance from the coupling point of the gas spring to the edge of the roof element or to the side part is increased.
    To that end, it has been determined that the coupling element can be pivoted about a construction component that extends transversely to the plane of the roof surface and that the linear drive is coupled to the coupling element at a distance from this axis. This results in an extremely simple construction. In this case, the design is chosen such that when the structural component which increases the roof surface is pivoted inwards, the coupling element is rotated in the opposite direction to the direction of rotation when this structural component is pivoted outwards from the vertical position. The angle of rotation is in the range of 180 °.
    In order to ensure that both during the outward swiveling and inward swiveling the structural component enlarging the roof surface acts on the coupling element, it is determined that this axis transversely to the plane of the structural component is inclined with respect to the plane of the structural component. This oblique position applies to two directions that are displaced relative to each other, this angle being in the range of 90 °.
    The linear drive in the end regions is usually provided with a connecting element in the form of a strip or a fork head. In order that no blocking takes place, it has been determined that the end directed towards the structural component that enlarges the roof surface is arranged in a pivot bearing. The pivot axis of the pivot bearing is also inclined with respect to the pivot axis of the coupling element. The imaginary extensions of these rotary axes are at an acute angle to each other.
    It has further been determined that the coupling element is designed in the simplest manner as a turntable or as a pivot lever. In order to minimize friction, it has been determined that both the pivot bearing and the coupling element are supported in roller bearings. In order to achieve this oblique position of the two shafts relative to each other, it is further determined that the coupling element, viewed in cross-section, is of angular shape, the two areas at an angle with respect to each other including an obtuse angle.
    The invention is further illustrated with reference to the accompanying drawings.
    Here: Figure 1 shows the linear drive and the construction of a sales car with a swiveling side wall in a highly schematic view, and Figure 2 shows the attachment of the linear drive to the swiveling side wall as an enlarged detail.
    Figure 1 schematically shows a column 10 on which the roof element (not shown) rests. The number of columns 10 on each side of the sales car depends on the length thereof. In the exemplary embodiment shown, the linear drive is a gas spring 11, the piston rod being pivotally coupled to the column 10. The housing of the gas spring 11 is coupled to a pivotable side part or another construction part for increasing the roof surface in a manner to be further explained. In the pivoted position of the side part, the piston rod of the gas spring 11 is moved outwards, as Figure 1 shows. The end of the gas spring 11 added to the pivotable side wall 12 is provided with a connecting element in the form of a strip. In figure 1 the hinge for supporting the side wall 12 is indicated by the reference numeral 15. The gas spring 11 is coupled to a coupling element 13 which is rotatably supported about a pin 14. As the figures show, this shaft 14 is inclined with respect to the surface of the side wall 12. In a manner not further shown, this shaft 14 or this pin is arranged obliquely in two directions with respect to the surface of the side wall 12, these two directions being at a 90 ° displacement be in relation to each other. The coupling element 13 is supported on the pin 14 by means of a roller bearing 18. The coupling element 13 can be a swivel lever or a turntable. The gas spring 11 is coupled to this coupling element 13 by means of the pivot bearing 16. On the side remote from the gas spring 11, this pivot bearing is a cylindrical pin which is supported in the coupling element 13 by means of a roller bearing 17. The figures show the outwardly pivoted position of the side wall 12. It is clear that in this position the pivot bearing 16 for the gas spring 11 is oriented away from the fixed roof structure (not shown). If the side wall 12 is pivoted due to the influence of forces, the coupling element 13 rotates about the axis of the pin 14 around an angle of approximately 180 °. After the side wall 12 has been pivoted to a certain angle, the otherwise required effort for a further displacement in the vertical position relative to the known embodiments is clearly reduced. After a certain pivoting angle has been deposited, the pivot bearing 16 is then positioned on the side facing the roof element, with respect to the axis of the stud 14. This position is also maintained in the fully pivoted position of the side wall. If the side wall has to be pivoted back into the outwardly pivoted position, the coupling element 13 rotates back into the position shown in the figures.
    As the figures show, viewed in cross-section, the coupling element 13 is of angular design, the two regions including an obtuse angle. It also follows from Figure 2 that the imaginary connections of the longitudinal center lines of the pivot bearing 16 and the pin 14 enclose an acute angle, but only in the outwardly pivoted position of the side wall 12.
    Insofar as the sales car is nevertheless provided with roof-corner components for forming a quadrangular overall roof surface, these are pivoted in the usual manner. The tailgate and possibly also the head plate can be coupled in the same way as the side walls 12 via the coupling element 13 to the linear drive or the gas spring, respectively. The coupling element 13 can be designed as a swivel lever or as a turntable.
    The invention is not limited to the exemplary embodiment shown. It is important that the end of a linear drive, or of a gas spring 11, added to the outwardly pivoting structural component, for example the side wall 12, is coupled to the side wall 12 via a rotatable coupling element 13, wherein in the outwardly moved position of the side wall 12 the distance to the roof element or to the hinge 15 is greater than when the side wall 12 has been moved partially inwards.
