Abstract

Hood cover for goods wagon, consisting of two extendable hoods which form a common plane when the wagon is closed and in which each hood is assigned running rails which are arranged above castors in the region of the external side members. The object of the invention is to simplify the hood actuation and to permit the transverse centre of the wagon to be loaded and unloaded by means of fork-lift trucks and cranes. According to the invention, an extension path which clears the sealing faces to the end wall is assigned to an inner hood and a larger extension path which permits the extended inner hood to move is assigned to an outer hood. The hoods are tapered in the lower third of the side-wall face and the end wall is prepared in a wedge shape towards the outer longitudinal carrier. The castors of the hoods have a spacing from the end of the hood with which the hoods can be moved out over the end wall. <IMAGE>

Description

Title of the invention
Hooded deck for freight wagons
Field of application of the invention

Hood cover for freight wagons, consisting of two expandable hoods, which have one joint when the wagon is closed Form level and each hood with running rails arranged over rollers in the area of the outer side rails assigned.

Characteristics of the known technical solutions

According to DE-PS 2910799 hood tops are already known in which the hoods over fixed parallel or movable rails in the longitudinal direction of the vehicle are movable. The hoods are spread by lifting the roof together with pivoting it out of the side wall surfaces. The swiveling out of the Side wall surfaces are made via issuing devices arranged in the area of the rollers and rails. directions. In addition, there are parts in the longitudinal center of the vehicle Hoods known in which the half-hoods each have a web arranged in the longitudinal direction, each of which is encompassed by a pair of rollers mounted at the ends of an expanding lever. (DD-PS 146 923) The opening and closing positions of the hoods are set by turning the lever

enables

These devices have the disadvantage of high mechanical complexity. In addition, the known solutions only reached a maximum of 50% opening of the side wall, so that the transverse center of the loading area is not accessible from the side of the vehicle or vertically.

Object of the invention

The aim of the invention is to simplify the hood actuation and to enable loading and unloading of the trolley transverse center 3d by forklifts and cranes.

Statement of the nature of the invention

The invention is based on the object by means of a specific arrangement and a modified spreading the hoods to meet the objective of the invention.

According to the invention the object is achieved in that the inner hood, which can be moved on the inner running rail, is assigned a spreading path, which releases the sealing surfaces to the front wall and that the outer hood, which can be moved on the outer running rail, is a larger Spreizweg is assigned, which allows a method of the spread inner hood that the Hoods in the lower third of the side wall surface on their Inside are tapered wedge-shaped towards the outer surface, that the outer contour of the end wall of the inside of the Following the hood, it is wedge-shaped towards the outer sill widened so that the rollers of the hoods have a distance from the hood end by which the hoods over the front wall can be moved out so that the half

Bow of the hoods in the upper roof area guideways äufweisen ₅ in which! Guide rollers and Spriegelverlängerungen the corresponding half hood feasible and can be moved by guide boundaries between an open and a closed position and that the hood at a distance of half Spreizweges are divided by the vehicle longitudinal center.

Another feature of the invention is the hood expandable by toggle lock or by a rope against a compression spring. The larger half hood is finished with a rain bar and the smaller half hood with a rain gutter. Parallel to the rails a safety shaft is rotatably mounted, which is locked via itfocken, hooks or pairs of levers the hoods locked in the closed position to the outer side rail »

Hach a further feature of the invention, the semi-domes in the area between the side wall surface and the roof area resilient or inflatable pillow or tightening straps may be arranged for load securing on the inside _e

Hood.

As can be seen from the drawings, FIGS. 1 and 2, the hood top has an inner hood 1 and a outer hood 2, which are assigned to an inner running rail 3 and an outer running rail 4.

When the car body is closed, according to FIG. 3, the hoods 1 and 2 form a flat surface. _f In the opening state of the inner shield 1 and the outer cover 2 have a different spreading distance, wherein according to Figure 2, the inner hood 1, the sealing surfaces 5 to the end wall 6 releases, and the outer cover 2, a method of the inner hood 1 in the vehicle longitudinal direction permits ο Here, As can be seen from Figure 2, the hoods 1 and 2 in the lower third of the side wall surfaces 7 tapers wedge-shaped from their inner side 8 to the outer surface 9, the outer contour 10 of the end wall 6 following the inner side 8 of the hood 1 and 2, to the outer side member 11 widened in the shape of a wedge.

The rollers 12 in this case have to cover end 13 at a distance _s with which the domes 1 and 2 on the respective end wall 6 and 6 can be moved 'addition.

In the roof area 14, the hoods 1 and 2 have guide tracks 16 on the half bows 15, in which guide rollers 17 and bow extensions 18 of the corresponding half-hood 1 'and 2 ^{f are} guided. Guide limits 19 determine the respective expansion path of the hoods 1 and 2 _O

The spreading of the hoods 1 and 2 can take place according to FIGS. 7 and 8 by means of a toggle lever lock 20 ? whereby the toggle levers 21 are dimensioned according to the different spreading paths of the hoods 1 and 2 «. The lever lock 20 is to be operated via a cable pull 22 or linkage and an operating device 23. The inertial forces of the hoods 1 and 2 can also be balanced by a spring compensation.

In FIG. 9, the hoods 1 and 2 are spread apart by a cable 24 which acts against a compression spring 25.

As can be seen from FIGS. 1 and 4, the hoods 1 and 2 are divided outside the vehicle longitudinal center 26, the distance from the vehicle longitudinal center 26 corresponding to half the spread. The larger half-hood 1 'and 2' ends with a rain bar 27 and the smaller half-hood 1 'and 2' with a rain gutter 28. A safety shaft 29 can be rotatably mounted parallel to the running rails 3 and 4, which locks the side wall surface 7 to the outer longitudinal support 11 in the closed position by means of hooks 30 or pairs of levers 31 with lock 32 via locking openings 33.

The lever pairs 31 with lock 32 can be used, and the lock 32 can be automatically pivoted in and out of the closing opening 33 via guide surfaces 34. To secure the cargo 35, according to a further feature of the invention, elastic and inflatable cushions 36 or tensioning straps can be arranged on the inner sides 8 of the hoods 1 and 2 between the side wall surface 7 and the roof area 14. With the arrangement of elastic cushions, the closing process of the expansion hoods creates an effective tension and thus

16O securing of the load reached.

With the solution according to the invention, more than 50 % of the loading area is released for loading and unloading when the car is open. This area can be craned and driven over by forklifts from the side of the vehicle. In addition, the wedge-shaped tapering of the side wall surfaces 7 in the expanded state of the hoods 1 and 2 keeps the required expansion path small and

in addition, when the wagon is closed, through the inclined inside 8 of the load 35 from the area of the smallest opening path, which is located directly on the outer side rail 11, held back. This increases the possibility of cargo jamming decreased. Furthermore, the simple components used allow a robust and trouble-free mode of operation.
