Description

251 1327

  The present invention relates to a freight wagon

  covered covers, the side walls of which each comprise at least two movable panels which, when they are closed, are situated in a plane-common and which, by means of an actuating device, can be selectively transferred by a transverse movement in a plane of sliding which extends in front of this plane, common, parallel to it and in which the panels can move in the direction of the longitudinal axis of the vehicle, each panel being associated with a rotary shaft wagon, which carries two spaced apart rails occupying enantiomorphic positions relative to the vertical longitudinal median plane of the shaft, the arrangement being such that on the inner rail bears, by means of pebbles, one of the panels, while that the outer rail serves

to guide the panel to move.

  Such freight cars are already known by the

  German Patent Application No. 2 157 258 However, it has been

  With these rail guiding devices, the rotation of the shaft requires a relatively high energy expenditure to transfer the panel into and out of its sliding plane, because the change in position of the rail relative to the vertical plane passing through the tree, has the consequence

  that each time the entire weight of the panel must be raised.

  Furthermore, it has also been found that when the wall panels are closed, their weight and the vertical mechanical constraints, for example, the jerks of the rails, impose on the bearings of the rollers or the rollers themselves forces so intense that the Bearings are damaged or the rollers are flattened in places On the other hand, when the car hits a bumper, the rollers are lifted from the rail and risk, depending on the intensity of the shock and the movement of the car, to fall back to the rails , thus making it impossible for the side wall to slide smoothly. A similar drawback may result from a displacement of the load which would then bear against the wall. In fact, under these conditions, the panel is connected to its guide. higher, is raised from the rail and

pushed laterally.

  The present invention aims at the perfection of

  a goods wagon of the type specified above in such a way that, on the one hand, when its side panels are closed, the rollers are not subjected to stresses, and on the other hand

  on the other hand, that its side panels are secured against

  external quotes so that they can not leave their tracks. The invention achieves the goals it has set itself by the fact that, between the inclined rails, are fixed on the shaft cleats which, when the panel is closed, engage under an outward-facing angle and, thus, raise the

rail rollers.
