»·, ·. ^{1 1}

The invention relates to a locking device for sliding walls or hatch roofs of freight wagons.

BACKGROUND OF THE INVENTION

The sliding wall latches of freight wagons fix sliding walls or hatches in certain positions in the longitudinal direction of the wagon. When opening the sliding wall, the sliding wall is located after the planting process on a rail that guides the walls and can be moved in the longitudinal direction of the wagon approximately to the center of the wagon to release the loading opening. If the vehicle is standing on a sloping track or not loaded, under certain circumstances, the sliding wall may start to move spontaneously. When closing, the sliding wall in the longitudinal direction of the wagon moves up to the front wall and is caught there in the end position. Upon engagement, it may happen that the sliding wall has to be retracted from the end position and retracted again in order to complete the closing. The unintentional movement of the sliding wall is to be prevented by locking devices. In the ORE report B12 / RP48, page A.2 / 11, a locking device is provided which automatically secures the sliding wall in the end position at the front wall and in the fully extended position against longitudinal displacement. The locking device consists of a movable pawl and a thumb, the pawl being located on the lower carrier of the sliding wall and the thumb on the underside of the carriage in both end positions. In this embodiment, the expensive and expensive arrangement of the movable pawl in the lower strip of the sliding wall is disadvantageous, since it must be opened and then closed again in order to use the actuating rod. The cross-sectional profile of the lower wall support often does not allow such weakening. Furthermore, the arrangement on the lower wall support is disadvantageous in that greater clearances arise due to manufacturing errors on many individual parts, by the elastic behavior of the components starting from the

-2level rails up to latch. Continuous functional safety is not guaranteed. The sliding wall lock can only be unlocked by using a latch and simultaneously sliding the wall. This means for the operator that he has to move the wall with one hand and with the other hand he must slide the latch, or he will slide the wall with both hands and the latch will extend the legs. This lengthy movement of the movements is physically strenuous for the operator, and the aforementioned disadvantages have led to the locking device not being able to be pushed on wagons with sliding walls.

SUMMARY OF THE INVENTION The object of the present invention is to provide a locking device which securely fixes the sliding wall to the underside of the car, does not weaken the supporting parts of the sliding wall, consists of a small number of individual parts, avoids greater clearances, guarantees long-term functional safety and guarantees an advantageous movement for the operator.

SUMMARY OF THE INVENTION The present invention is directed to a sliding wall latch and hatch roofs of freight wagons for locking and releasing sliding walls or hatches in the longitudinal direction of the vehicle at end positions consisting of a latch and a thumb, the thumb and latch corresponding to each other in the end position; a sliding wall mechanism is secured to the carriage by a locking pin, transverse to the carriage, and the leading lever with the guide thumb is pivoted via a pivot joint to a locking pawl provided with a recess, the locking pawl together with a starting lever movably arranged on the locking pawl the pivoting joint pivoted to the wagon body and the deflection regions of the drive lever and the locking pawl are limited by stops.

The start lever can be rigidly attached to the locking pawl and the locking pawl is held in the locked position by the energy storage elements.

The arresting pin can be rigidly attached to the underside of the car and the start lever and the locking pawl are pivotably attached to the sliding wall movement mechanism via the pivot joint.

According to a preferred embodiment, the arresting pin may be mounted on the lever, pivotally arranged at the bottom of the car through the pivot joint, and the locking pawl provided with a guide thumb and recess is arranged on the movable mechanism of the sliding wall via the pivoting joint.

According to a further embodiment, the locking pin can be mounted on the lever, pivotally mounted on the sliding wall movement mechanism via a pivot joint, and the locking pawl provided with a guide thumb and a recess is pivotally mounted on the underside of the car through the pivoting joint.

In the following, an exemplary embodiment of the invention will be explained by means of the figures.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the main subassemblies 1, the front wall 2, the central portal 3, the sliding wall 4 are shown from the wagon with sliding walls. At least one of the sliding walls 4 is opened for loading and unloading the wagon. For this purpose, the ejection device 5 according to FIG. 2, 3 and 4, the sliding wall 4 swings outwards and is mounted on the rail 6. Thereafter, the sliding wall 4 may slide in the longitudinal direction of the wagon until about half of the longitudinal side of the wagon is released. When closing the longitudinal side of the wagon, the sliding wall 4 slides in the direction of the end wall 2 until it reaches the end position according to FIG. 2 and 5 do not encounter

-4bumper 7. The locking device prevents the sliding wall 4 from moving back. For this purpose, a locking pin 9 is rigidly attached to the movement mechanism 8 of the sliding wall 4. This locking pin 9 lifts the start lever 10 by means of a guide thumb when the sliding wall 4 enters the end position.

The pivot lever 10 is pivotably mounted via a pivot joint 16 'on the locking pawl H. Through a stop 13' which is located on the pivot lever 10 in such a way that the stop 13 'can abut the upper side of the pawl and thereby limit the lowest position. At the same time, the locking pawl H, located pivotably via the pivot joint 16 at the bottom 1 of the car, is lifted. Upon further movement of the sliding wall 4 to the end position, the locking pawl H will fall under its own weight as shown in the figure, or sprung in a known manner with a semicircular shape recess 14 onto the locking pin 9. In this state, the sliding wall 4 is secured in the longitudinal direction of the wagon. For complete closing, the sliding wall 4 is swung in and down by the ejector 5. 3, the locking pin 9 leaves the recess 14 'I, * ^{1 of the} locking pawl U and the locking pawl U falls down to the stop 13. When opening, the sliding wall 4 is pushed outwards and upwards by the setting device 5. Since the locking pawl H abuts against the stop 13, the locking pin 9 extends along the upper edge of the locking pawl H. In the displacement process of FIG. 4, in the initial phase, presses the guide thumb 12 of the drive lever 10 downwards with the locking pin 9 and the sliding wall can pass freely. When the locking pin 9 has passed along the guide thumb 12, the drive lever 10 falls back under its own weight or springed up to the stop 13 'back to the locking pawl 11 and the readiness for locking is again restored. It is within the scope of the present invention that the lead-in lever 10 is rigidly attached to the locking pawl H and the locking pawl H is held in the locking position by known energy-storing elements 15, for example by springs. Further embodiments of the arrangement of the locking pin 9 and of the start lever 10 and the locking pawl H are provided. the pin 9, which is attached to the lever 19, pivotally attached via the pivot joint 18 to the bottom 1 of the wagon and the locking

With a detent device according to the invention, the sliding wall 4 is preferably securely locked in the CLOSED position. When opening the sliding wall 4, this brushing device is released automatically and uncomplicated so that no additional operator effort is required.
