OPENABLE ROOF OF THE LOAD

The invention relates to the roof of a closed load compartment of a truck or trailer, which opens in such a way that the roof structure enables unloading and unloading without hindrance from the side and top of the load compartment.

5 In order to protect the goods being transported, loose covers, partly fixed and fixed structures are used during transport.

A previously known solution is the use of cover arches and a cover, the so-called chapel. In this solution, the protective cover 10 is supported by either a fixed or partially demountable frame. Loading and unloading of the load compartment takes place through the stern parts or between the cover arches by wrapping the protective cover from the side up and turning one of the pallet edges down, or by removing the required number of side columns and turning the pallet edges down 15 at the desired point. The roof frame supporting the cover stays in place on the front and rear ends.

Despite its low cost, this solution has many disadvantages. Manual handling of a dirt cover in traffic is inconvenient, it is cumbersome to wrap up and the cover 20 does not provide very good protection. In addition, when loading or unloading from the side, the vertical posts of the cover arches must be removed, which causes additional work.

The previously known solution is a closed fixed load compartment, the rear wall of which is formed by double doors and the 25 sides of which may be provided with a single access door or double doors. This solution provides good protection for the goods being transported, but limits the use of the load compartment for the transport of goods of different lengths. In addition, it requires a precise loading sequence so that the unloading of the load 30 can be done in the desired order without having to unnecessarily unload part of the load.

A previously known solution is to equip the side of a closed fixed load compartment with so-called full-door doors and rear doors of the load compartment with double doors. In this solution, the possibilities of using the load space are better, because long goods 5 can also be loaded from the side and there is no need to follow such a specific order so much when unloading. However, the disadvantage of the solution is the fixed roof, which makes it impossible to load with a crane and which also hinders loading with the truck from the side of the load compartment. When using a truck with a long mast, make sure that the mast does not break the edge of the roof and therefore the tilting of the truck mast cannot be exploited. The fixed roof also prevents free lifting when the truck is stacked on top of each other in the load compartment. In this case, the upper part 15 of the load compartment is not used to the extent of the free space required for truck operation.

A previously known solution is to equip the load compartment with a sliding roof, rear doors and possibly also side doors. In this solution, the roof moves on the slide rails half or 20 up to 3/4 of its length forward, whereby part of the roof slides over the load space outside it. In this solution, the possibilities of using the load compartment are better, because loading with a crane through the roof is partly possible. However, the disadvantage of the solution is that even if the load compartment side 25 is provided with doors that open to the full side, the sliding rails required by the sliding roof at the top of the load compartment interfere with the loading of the load. The usefulness of this solution is also reduced by the snow and ice accumulating on the roof and the slide rails, which prevents the roof from moving. 1 li

There is still a need for a load compartment whose roof and wall structures are as open and easy to open as possible so that support structures that impede loading and unloading do not remain when the roof or sides are opened and that the structures can be tightly closed.

It is an object of the present invention to provide a novel opening roof of a load compartment which is simple, easy to use and compact.

In particular, the object of the invention is to provide a roof according to the invention 5, which, by opening the roof, enables unobstructed access to the load space from above and also from the side without obstructing the roof structures.

It is a further object of the invention to provide a roof according to the invention which, when the load compartment is provided with fully opening doors, enables the load compartment to be freely loaded with a crane also from the side. This eliminates the need to lift loads unnecessarily high.

It is a further object of the invention to provide a roof according to the invention which, when the load compartment is provided with doors that open to a full height, enables unobstructed, safe and efficient loading from the side of the truck. With a forklift, lifting can be done freely, because there is no fixed edge edge of the roof. In addition, the tiltability of the truck mast can be utilized and loading can be done with a long mast truck. 20 The load compartment can also be filled as accurately as possible in the height direction, because at the time of loading the bales can be raised higher than the roof height.

It is a further object of the invention to provide a roof according to the invention which diversifies the use of the load compartment in transport tasks. The transport of various goods in outward and return loads is possible when the load compartment can be loaded more freely.

It is a further object of the invention to provide a roof according to the invention which makes it possible to build the load compartment 30 only to the height necessary to protect the goods to be transported. When using the roof solution according to the invention, the loading can be done freely without any restriction on the height of the load compartment or the loading means used. The load compartment can be built lower than at present, which reduces the air resistance it causes and 5 transports become more economical.

It is a further object of the invention to provide a roof according to the invention which, in combination with the previously known full side opening and rear doors, makes it possible to build an open and close closed load compartment 10 so tight and protected that snow and ice do not accumulate at the joints.

It is a further object of the invention to provide a roof solution according to the invention in which the opening and closing of the roof 15 can be done easily and lightly and in a controlled manner without the need to climb in any way or without having to dismantle any support structures to access the load compartment.

The roof solution according to the invention thus eliminates the drawbacks which occur in previously known load-space structures.

In order to achieve the above effects, the invention is characterized by the elements set forth in the claims.

The invention is explained in detail below with reference to the accompanying drawings.

5 82646 and the roof (3) according to the invention opening.

Figure 3 shows a situation in which the roof (3) of the load compartment (2) is fully open.

Figure 1 shows 5 load compartments (2) with a roof (3) according to the invention mounted on a truck (1). The roof (3) is divided into longitudinally hinged parts and the side of the load compartment (2) is provided with fully opening doors (4), which also consist of hinged parts.

At the edge of the roof (3) there is a sliding rail (6) for the side doors and the sliding tracks of the side doors 10 coincide with the edge of the roof when the roof is closed.

A hydraulic cylinder (7) and a lever arm (8) are attached to the front wall of the load compartment (2) outside it, by means of which the opening and closing of the roof (3) is controlled.

By placing the hydraulic cylinder (7) outside the load compartment, 15 the available space remains as large as possible and the contamination of the transported goods with oil is prevented if the hydraulic system leaks from any point.

Figure 2 shows the load compartment (2) whose roof (3) is opening.

The roof is divided in the middle by a full-length sealed hinge 20 (9) into two parts and hinged at one side by a full-length sealed hinge (10) to the side wall of the load compartment.

At the corners of the free side of the roof there are rollers (11) which run on sliding rails (12) in the frame of the front wall and the rear wall.

The end ends of the roof have a double seal and the free side 25 has a standard seal for doors that open to a full side.

The roof is opened by means of gas springs (13) articulated to the side wall of the hydraulic cylinder (7), the lever arm 82646 (8) and the load compartment and to the other half of the roof. The hydraulic cylinder (7) controls the movements of the roof and the opening gas springs (13). The hydraulic cylinder (7) can also be used to facilitate the opening of the roof if there is a snow load on the roof.

Attached to the side wall of the load compartment is a load compartment-long shaft (14) with guide arms (15) running on guide rails (16) attached to the ceiling and preventing the roof from twisting.

Figure 3 shows a load compartment (2) with side doors (4), rear doors (5) and a roof (3) according to the invention open for loading a load. Access to the load compartment is completely unobstructed from the top and from the side. In addition, loading can be done through the rear doors (5) of the load compartment.

In particular, it should be noted that the solution according to the invention is applicable to other types of enclosed and openable spaces than cargo spaces. In addition, it should be noted that the invention has been described above with reference to only one illustrative embodiment. However, it is not intended to limit the invention in any way to this example only, but the invention may vary within the scope of the appended claims.
