    A general problem with boxes arranged on vehicles is that during a very strong braking, the load moves forward, seen in the normal direction of travel of the vehicle, whereby the box must prevent the load from leaving the box.
    Brief description of the invention.
    The object of the invention is to provide a box which is intended to be arranged on vehicles, where the volume of the box can be changed between a smaller volume when the box is not in use and a larger volume when the box is used. That the box can be changed between the two volumes, without the need for a larger force. That the box can absorb the forces that the load gives rise to during a heavy braking.
    In order for the volume of the box to be easily changed between the two volumes when the box is not used, is in the folded position, and when the box is used, is in the folded position, the middle part of the box must be of a material that is flexible, so that the two positions, folded position and folded position, the middle part can easily be folded or stretched out. To move the upper part between the two positions, folded position and folded-up position, and to keep the upper part in folded-up position, the box has support legs, which are attached to the lower part of the box and to the upper part of the box.
    In order for the box to be able to absorb the forces that the load in the box can give rise to during a heavy braking, the support legs of the box must be attached to the lower part of the box and to the upper part of the box so that the support legs can absorb the forces generated during heavy braking of the vehicle.
    In order to obtain a box where the volume of the box can be changed and where the box can withstand the forces caused by the load during a heavy braking, the box according to the invention has a load-bearing element at the side of the box that is forward, seen in the vehicle's normal travel direction. at a distance from each other along the sides of the box that are parallel to the normal direction of travel of the vehicle.
    Brief description of the drawings.
    With reference to the accompanying drawings, a more detailed description of some exemplary embodiments of the invention follows.
    In the drawings, Figure 1 shows a box in a raised position, Figure 2 a box in a folded position and Figure 3 a section of the box along the section A-A in Figure 1.
    Detailed description of the preferred embodiment.
    Figure 1 shows a box (10) according to the invention in the folded-up position where the box consists of a lower part (11), an intermediate part (12) and an upper part (13). The lower part (11) of the box (10) is prepared so that the box (10) can be attached to load carriers (14) which are arranged on a vehicle, usually over the roof of the vehicle. On the sides of the box (10) which are parallel to the normal direction of travel of the vehicle, load openings are arranged, in the example shown the load openings are covered with load hatches (15). Preferably, the cargo hatches (15) are of the same material used in the intermediate part (12). The intermediate part (12) and the load hatches (15) must be of a material that prevents the load in the box and the inside of the box from being exposed to weather and wind. In order for the load hatches (15) to connect to the intermediate part (12) so that neither the load nor the inside of the box is exposed to weather and wind, the connection can be designed with a zipper (16).
    Figure 2 shows the box according to figure 1 in a collapsed position, where the upper part (13) of the box (10) abuts against the lower part (11) of the box (10). In the embodiment shown, the lower part (11) of the box (10) and the upper part (13) of the box (10) have recesses (17), these give the box (10) a maximum load height with the smallest possible height of the box (10), when the box (10) ) is in the folded position. Only the free edge (18) of the lower part (11) at the front side (19) of the lower part (11) abuts against a corresponding free edge (20) on the front side (21) of the upper part (13) and correspondingly at the rear side (22) of the box (10). ). As the box (10) has a small height in the collapsed position, the box (10) has a low air resistance and can remain on the vehicle when the box (10) is not in use, with only a slight increase in the vehicle's fuel consumption as a result.
    As the load in the box (10) will cause a large load on the box (10) during a heavy braking of the vehicle, the parts of the box (10) and the attachment of the box (10) to the load carriers (14) must be able to withstand the forces generated. Since the material in the intermediate part (12) of the box (10) must be very flexible in order to enable the upper part (13) of the box (10) to be easily moved between the two positions, folded position and folded-up position, such a material has difficulty in resisting the forces that arise during a heavy deceleration. Attachments of the intermediate part (12) to the lower part (11) of the box (10) and the upper part (13) of the box (10) can also give rise to problems in the event of heavy braking of the vehicle, by separating the intermediate part (12) from the lower part (11) and the upper part. (13). -w-ß-ws In order to eliminate these problems, according to the invention a load-bearing element (23) is arranged between the lower part (11) of the box (10) and the upper part (13) of the box (10) on the inside of the box (10), at that side of the box (10) which is forward, seen in the normal direction of travel of the vehicle, so that the intermediate part (12) is covered by the load-bearing element (23). Figure 3 shows a section through a box (10) according to a preferred embodiment of the box (10), with a load-bearing element (23). The box (10) has support legs (24) arranged in the corners of the box (10), the support legs (24) on the two sides of the box (10) which are parallel to the normal direction of travel of the vehicle are connected to each other into units, each unit consisting of two U-shaped elements a lower U-shaped element (25) and an upper U-shaped element (26), the free ends (27) of the lower U-shaped elements (25) and the free ends (27) of the upper U-shaped elements (26) are connected to hinge mechanisms (28). The hinge mechanisms (28) are only shown schematically as it does not form part of the invention. The lower U-shaped elements (25) are rotatably mounted to the floor section (29) of the lower part (11) with lower attachments (30), the lower attachments (30) being arranged in connection with the free U-shaped elements (25) ends (27), so that the lower attachments (30) at each lower U-shaped element (25) are at a large distance from each other. The lower fasteners (30) are attached to the floor section (29) with suitable fasteners such as rivets (not shown). The upper U-shaped elements (26) are correspondingly rotatably mounted to the roof section (31) of the upper part (13) with upper attachments (32).
    The load-bearing element (23) in the preferred embodiment shown is provided with lower load-bearing straps (33) and upper load-bearing straps (34) which are attached to the lower corners and upper corners of the load-bearing element (23), respectively. The lower load-bearing straps (33) are attached to lower attachment points (35) arranged at the two attachments (30) for the two lower U-shaped elements (25) which are closest to the front side (19) of the lower part (11). The upper load-bearing straps (34) are similarly attached to upper attachment points (36) arranged at the upper attachments (32). To keep the load-bearing element (23) in the vicinity of the intermediate part (12) at the side of the box (10) which is forward, seen in the normal direction of travel of the vehicle, the lower load-bearing straps (33) are fixed to the lower part (10) of the box (10). 11) with lower temporary brackets (37). The upper load-bearing straps (34) are attached in the same way to the upper part (13) of the box (10) with the upper temporary brackets (38).
    When the load in the box (10) moves forward during a heavy braking, the load will hit the load-bearing element (23) and the lower load-bearing straps (33) and the upper load-bearing straps (34) will come loose from the lower temporary brackets (37 ) and the upper temporary brackets (38). Thereafter, the force from the load will be transmitted to the lower attachment points (35) at the lower attachments (30) and to the upper attachment points (36) at the upper attachments (32). The forces from the lower attachment points (35) are transmitted to the lower part (11) of the box (10) and will load the lower part (11) as a traction force. The forces from the upper attachment points (36) will be transmitted to the support legs (24) and will affect the lower part (11) of the box (10) at the front lower attachments (30) as a compressive force (F1) and the lower part (11) of the box (10) ) at the rear lower attachments (30) as a traction force (F2). To keep down the cost and weight of the box (10), the lower part (11) of the box (10) and the upper part (13) of the box (10) are made of plastic material, for example ABS plastic, which better withstands a higher load from a compressive force than from a traction.
    With a large distance between the lower fasteners (30), the traction force which affects the fastening elements for the rear lower fasteners (30) will be at a level which does not cause any problems for the fastening elements to cope.
    The load-bearing element (23) must be easily foldable when the upper part (13) of the box (10) is moved from the folded-up position to the folded-up position and easily extended when the upper part (13) of the box (10) is moved from the folded-up position to the folded-up position, at the same time as the material in the load-bearing element (23) must have high strength. In a preferred embodiment, the load receiving element (23) is made of a net. Where the net has some form of reinforcements along the edges, where for example the lower load-bearing straps (33) and the upper load-bearing straps (34) can be attached. In a simpler embodiment, the load-bearing element (23) can be directly attached to the lower part (11) and the upper part (13), the lower load-bearing straps (33) and the upper load-bearing straps (34) and the lower fastening points (35) and the the upper attachment points (36) are not necessary but instead separate attachments of the load-bearing element (23) must be arranged at the lower part (11) of the box (10) and at the upper part (13) of the box (10).
    The support legs (24) do not have to be designed as lower U-shaped elements (25) or upper U-shaped elements (26) but can be designed as L-shaped elements or as support legs (24) attached to bearings, where the bearings have a larger extending along the sides of the box (10) that are parallel to the normal direction of travel of the vehicle.
    To obtain a box (10) where the volume of the box (10) can be changed between a smaller volume, in the folded position and a larger volume in the folded position, where it is easy to move the upper part (13) of the box (10) between the two positions folded position and folded-up position and a box (10) which can withstand the forces which the load in the box (10) can produce during a heavy braking of the vehicle, the box (10) according to the invention has a load-bearing element (23) inside the box ( 10) on the side of the box (10) which is forward, seen in the normal direction of travel of the vehicle, and support legs (24) where the attachment of the support legs (24) to the lower part (11) and upper part (13) of the box (10) has fasteners (30) , 31) at a distance from each other along the sides of the box (10) which are parallel to the normal direction of travel of the vehicle. Although the invention has been described with reference to some preferred embodiments, the box (10) can be modified in a number of ways within the scope of the inventive concept as presented in the stated claims.
