Sliding wall and ceiling mounters for freight wagons

BACKGROUND OF THE INVENTION The invention relates to sliding wall and ceiling positioning devices for freight wagons, in which sliding walls and ceilings can be moved by sliding rails and wheels and the roof and wall portions are in a closed position in the same plane, whereby position in the pivot area to move to the end of the sliding rail, and said end of the sliding rail forms a sliding roof pivoting member 10 which carries the support wheels in the open position of the sliding roof.

For safety reasons, the ORE-B12 / RP 48 requires sliding-wall vehicles to be provided with safety devices that prevent accidental sliding walls from moving into the closed position. Therefore, it is known to locate mechanical lever operated locking devices as an accessory in the lower part of the slide rails apart from the slide wall actuators. They cause extra trouble, can be damaged and are complicated to manufacture.

DE 33 12 001 discloses devices for closing the movable roofs of railway wagons 20 from closed position to open position and vice versa, where three different wheels are used to control the wall sections in the swiveling area and to move the walls * * :: longitudinally. One wheel is used to move the walls longitudinally in the open position of the roof, the other .. I: The support wheel, by means of an auxiliary rail, carries the foot of the slide and acts as a pivoting member for the wall parts. A third wheel, rotated on a vertical axis, ensures straightforward passage of the wall sections when moving outside the swivel range.

This shape contains many moving parts, which makes its manufacture relatively expensive.

From DE 35 24 721, it is known to use impellers which have additional cylindrical auxiliary sliding surfaces and which rotate in a pivoting area with a separate auxiliary wheel. Additional guide rails are used for laterally guiding the sliding wall portions in the region of the sliding rail recesses. A disadvantage of this form is that the auxiliary rail and the second horizontal guide rail extending upwardly between the flanges of the wheel have to be serviced in the swiveling area of the vertical steering. Because of the presence of two auxiliary rails in the pivoting area, the manufacture and maintenance is very complicated. This arrangement further causes the parts of the walls 5 to be heavily moved as they are moved, since the sliding wheels are guided at two points in their circumference.

The object of the invention is to simplify the use of sliding walls and ceilings when turning them, to increase the ease of movement of the moving parts of the sliding walls and ceilings, while at the same time reliably guaranteeing the orientation accuracy during transfer.

The object of the invention is solved in that the end of the slide rail is approximately obliquely divided in cross section and consists of a lower / outer part and an upper / inner part, and the upper part of both parts forms a symmetrical curve corresponding to the shape of the the lower / outer portion forming a fixed groove which receives the slider flange when driving over the pivoting area of the closed sliding wall, further comprising a support surface for supporting the upper / inner portion of the sliding rail in the open position of the sliding wall; which carries the sliders in the open position on the wall.

The upper / inner portion of the slider head acts as a pivoting member for moving the sliding wall from a closed position to an open position and vice versa, and carries the I * · • sliding wheels in the open position of the wall. According to other features of the invention, the lowest point of the support surface of the slider wheel, when viewed in cross section, is a vertical dimension "c" from the wheel plane and a horizontal dimension "d" from the center of the pivoting area. The slides are at this lowest point of the groove rails at the end position of the open position of the sliding walls. The end stops limiting the length of the slides are also located in this position of the respective sliding wall.

The invention will now be illustrated by means of an exemplary embodiment. In the drawings: »· · 111697 3

Figure 1 shows a freight wagon in which the devices according to the invention are located.

Figure 2 is a sectional view A-A of the pivoting area of the sliding ceilings and walls of Figure 1.

Figure 3 is a sectional view B-B of Figure 2.

The adjusting devices 1 according to the invention are suitable for both sliding-wall and roof-mounted freight wagons. In the exemplary embodiment, Fig. 1 shows a sliding wall trolley having two roof halves and in which the sliding walls 2 can be pushed onto one another by means of wheels 3 running on the sliding rail 4. The pivoting regions 5 of the sliding walls 2, whereby they are pivoted from closed to open position and vice versa, are always at the same distance "a" from the carriage ends 6 and the center, and their distance 15 "b" is always the same. The length of the sliding rails is limited by end terminals 7 adjacent to the outer pivoting areas 5 in Fig. 2. The dotted dashes show the actuators 1 and the sliding wall 2 of the slide wheel 3 in a closed position 20. The end 8 of the slide rail is divided approximately obliquely in cross-section 5 in the pivoting area 5. It consists of a lower / outer part 9 and an upper / inner part 10, and the upper side of both parts forms a symmetrical curve corresponding to the flange of the slide wheel 3. The parts 9, 10 forming the sliding rail head 8 in the pivoting area 5 are thus arranged in the form of a fixed wall 11 · of the sliding rail 4 extending over the entire displacement area, and provide for a smooth movement of the sliding wall 2. The lower / outer portion 9 of the slide rail head 8 forms a fixed groove rail 12 which receives the closed slide wall 2 of the flange 3 of the slide wheel 3 when traveling over the pivot area. The upper / inner part 10 of the slide rail 8 serves as a pivoting member 13 for moving the sliding wall 2 from the closed position to the open position and vice versa. The pivoting member 13 is in the open position of the sliding wall 2 on the supporting surface 14 of the groove rail 12. The outer flange of the sliding wheel 3 then engages the groove rail 12 and the inner flange in the groove of the pivoting member 13.

: '' ': The horizontal support and the vertical support of the scroll wheel 3 are then provided by the pivoting member 13 alone. The pivot 15 surrounding the pivot 13 is known to prevent vertical movement of the pivoting member 3 from the pivoting member 13. less than the level of movement 17 of the outer flange of the slide wheel 3. In the horizontal direction 5, the support point 16 is, as shown in Fig. 3, at a distance "d" from the center 18 of the pivoting area 5. This embodiment provides a reliable control of the slider 3. When moving the opened sliding wall 2 over the closed sliding wall 2, vertical and mutual horizontal control of the opened sliding wall 2 is provided in the pivoting area 5 through which the outer flange 10 of the sliding wheel 3 passes. The lowest support point 16 causes the sliding wall 2 to engage in the open end position, since the wall is locked in this position and can only be released with some force. With the setting device 1 according to the invention, it is possible to move the sliding wall and ceiling lightly, although no additional guide parts are used and the guide rollers are few. The groove rail 12 and the pivoting member 13 15 ensure reliable control of the sliding wheel 3 in the pivoting area 5. In addition, the sliding wall and ceiling portions are adequately shielded from horizontal and vertical forces and adequately guided over the sliding rail head 8. The end position of the open position achieves very little manufacturing effort and a simple way of securing the sliding wall and ceiling components.
