"Sliding door for trucks"

Italian priority of July 24, 1969 from the , Italian patent application No. 33 612 A / 69

The statutory restrictions on the external dimensions of trucks and trailers in road traffic as well as the modern Güteriadeverfahren, in which the goods are stacked in the form of pallets on loading surfaces, which together be lashed with the cargo underline the need to To offer an optimal loading capacity with the same truck dimensions.

A main obstacle to what has been mentioned so far is the holding and opening structures of the truck doors independently of the respective type. '

The aim of the invention is therefore to create a special opening system for sliding doors of trucks, with the help of which a complete opening of the Doors on one side of the truck is possible and that with omission the disturbing central strut, which, if not completely eliminated in some cases, can at least be kept very narrow.

The opening system according to the invention has the fundamental advantage that a smooth surface is provided when the doors are closed. In addition, the two parts delimit exactly to each other so that there is no space between them.

This opening system is made possible by small rollers

possible., which are housed in the door thickness itself and therefore do not take up any dead space for the interior of the truck or impede the load. Each of the two parts of the sliding door, which form the entire sliding door can be moved freely in the open position with respect to the respective other part.

In contrast, each sliding door part takes its specific place in the closed position.

The invention consists in accommodating a profile in the upper part of the side opening, which forms the inner half of the Assumes wall thickness and serves as a rail for the rollers to which a sliding door part is attached.

The outer half of the wall thickness is from another Profile of the same cross-section and opposite to the first one. .

This second profile is not fixed, but suspended over its entire length on a hinge, i.e. on . a sheet metal strip, the upper part of which is movable with the outer one Area of the frame of the truck is connected.

This strip can be swiveled upwards in such a way that the sliding door panel protrudes from the wall thickness ^ and lifts up slightly. This can thus slide along the running rail and pushed over the other sliding door panel will. In contrast, however, the now underlying Slide the plate and occupy the space that has become free.

The peculiarities and features of the invention The construction as well as its functionality are illustrated by the following Description even clearer, which refers to the accompanying drawings and exemplifies a possible application of the invention.

- Fig. H shows the two parts of the sliding door in the open position

on a truck,

Within the drawings, the structure of the Trucks are shown, which has an opening in a side wall, which is occupied by the two sliding door parts 2 and 3, the latter in the closed position being exactly aligned with one another and with the side wall.

The sliding door part 2 can be moved and is suspended from the longitudinal plate Ί via the rollers 5 on the profile 6, which is connected to the corresponding inner side (thickness) of the wall 7 on the upper part of the opening mechanism. That said Profile has this opening over its entire length.

The plate k is connected to the plate 8 in the sliding door part 2, which in this case is made of plastic material, but on the other hand can be made of any other suitable material.

The sliding door part 3 is fastened in the same way to a running rail 9, which is opposite to the running rail 6 has the same but opposite profile.

The running rail 9 is at 10 on a Zapferfinit Sheet metal strip 11 connected, which is also movable via the movable lamella 12 on the structure of the truck.

The sheet metal strip 11 can be rotated and lifted up to the position shown in drawing 3, namely over the rod 13. This rod is operated via the lever 14 and connected via a slot guide 15 to an extension piece 16 running perpendicular thereto.

If this lever 14 is moved into the closed position, it causes this the lifting of the lower and pivotably mounted at 18 belt 7. This belt is now in the closed position Sliding door parts 2 and 3 firmly, which are therefore no longer to the side can move. ;

Thus, there is no projection whatsoever for actuating the sliding door parts in the hold and no center post at the closing point of the door parts necessary.

The goods to be loaded can also be as far as aim Edge of the loading area can be stacked without impairing the closing process of the sliding door parts would be, since the conclusion is made by frontal insertion of a plate into the space left free by the other plate.

Finally, it should be mentioned that the opening and closing system brought about by the means described "Upward and outward translational movement of one of the two sliding door parts around the running rail serving as suspension.

This translational movement gives free space for moving the other sliding door part, while the already after outside moving first sliding door panel can be moved freely from one end to the other on the rail serving as a suspension The invention also includes an improved operating system for sliding doors of trucks.

This system can depending on the required functional principles can also be created with more than two adjacent sliding door parts.

It is to be understood that the example) given description of the invention encompasses all variants that can be derived similarly in the invention.
