A covered freight wagon, the side walls of which in each case consist of at least two movable wall sections. - Täckt godsvagn, vars sidoväggar bestar av atminstone tvä rörliga väggpartier.

The present invention relates to a covered freight wagon, the side walls of which consist of at least two movable wall parts in a common plane in the closing position and moved transversely by a control device to a push plane optionally in front of the common plane parallel to it and movable in this plane over the lower rail , wherein the upper guide consists of a rotating shaft with a guide lever attached thereto and a claw engaging the profiled upper part of the wall part.

Such a freight wagon is known from DE-GM 81 23 714.6, in which the free lever arm engages the guide rail from above and the wall part leads to both the closing plane and the transfer plane, and in which the fixed lever arm is fixed to the shaft. The structure and dimensions of the lever arms have achieved a fixed building height, which is not available in certain applications. Also, precise control of the sliding door from the closing plane to the transfer plane and vice versa has not been obtained, because the free lever arm is attached to the articulated fixed lever arm on the one hand and is supported without a support point on the upper guide rail of the push wall. Thus, in the case of the construction tolerances and deformations required for the use of the push wall and in particular the upper control of the push wall, the forced lever ratios have an adverse effect on the power transmission ratio.

The object of the invention is to form a lever so that in the case of a low building height a controlled, reliably reproducible transfer movement of the sliding door from the closing plane to the transfer plane is achieved.

According to the invention, this is solved according to the characterizing part of claim 1.

An embodiment of the invention is shown schematically in the drawing, in which:

Figure 1 shows a cross-section of the upper guide in a closed wall section.

Figure 2 shows a cross-section of the upper guide in the opened wall part.

Figure 3 shows a top view of Figure 2.

A lower guided rotating shaft 3 is mounted on the upper jaw 1 of the freight car for each wall part 2, which supports a non-rotatable control lever 4 connected by means of a lever arm 5 articulated with a claw 6 which engages the profiled upper side of the wall part 2. The lever arm 5, which on the one hand is articulated to the control lever 4 and on the other hand is mounted together with the mandrel 6 on a shaft 7 running horizontally and parallel to the shaft 3, is moved axially perpendicular to the shaft 7 by a gripping handle 8 engaging it. a rotating sleeve 9 is pushed onto it, with which a handlebar 8 is fixedly connected.

In order to ensure a better stability of the upper control, a successive arrangement of the control levers 4 and the lever arms 5 is provided, whereby the lever arms 5 are connected to each other by means of a stiffening plate 10 at the top. In this case, the mandrel 6 on the rear side is mounted on two outwardly located strips on the shaft 7, whereby the sleeve 9 is mounted on the shaft 7 so that the handlebar 8 is centrally located between the lever system.

To move the wall part 2 from the closing plane according to Fig. 1 to the pushing plane according to Fig. 2, the shaft 3 is rotated clockwise. Simultaneously with this rotational movement, the joint 12 connected to the lever arm 5 rotates the control lever 4 in rotation, as a result of which the lever arm 5 is pushed outwards, the shaft 7 in approximately the same horizontal plane Due to the connection of the shaft 7 with the claw 6, these also become pressed outwards and, due to their structure, take them with them to the upper side of the wall part (2).
