Definitions

• the invention relates to a luggage transport case with a base element which can be fastened on the roof of a motor vehicle, a cover element, and at least one foldable or extendable wall element provided between the base element and the cover element, the base element and the cover element being seen in the direction of travel in front area and / or in the rear area are each connected to at least one connecting element.
• Luggage transport cases of this type are known, for example, as roof boxes for passenger cars.
• the total air resistance of the luggage transport case results from the product from its cross-sectional area in the direction of travel, its air resistance coefficient and the dynamic pressure of the air, which depends on the air density and depends on the speed of travel.
• the air resistance coefficient of the luggage transport case can only be optimized within certain physical limits and is already close to the technically feasible optimum in many known luggage transport cases. In the case of the luggage transport cases known from the prior art, a reduction in the cross-sectional area is always accompanied by a restriction of the storage space.
• DE-OS 24 42 104 describes a foldable luggage holder, which consists of a flexible bag, which is attached to the roof of a motor vehicle.
• This bag has a number of fastening straps which extend around the side webs and the top of the bag and has resilient fastening devices with which the bag can be clamped to the vehicle roof. The fastening straps and the fastening devices can also be hooked together so that the luggage can be lashed in the flexible bag on the car roof.
• the flexible bag should be easy to install and remove, as well as completely foldable, and only take up a very small storage space when not in use.
• the unloaded luggage holder cannot remain on the car roof without the wind blowing up the bag during the journey.
• this bag has a poor drag coefficient because it flutters. In addition, it causes unpleasant wind noises.
• the surface of the flexible bag is determined by the shape of the luggage items located therein. This means that even smaller, but unfavorably shaped pieces of luggage can cause high wind resistance.
• US Pat. No. 3,160,435 describes a sleeping cabin on the roof of a motor vehicle, the lid of which can be raised for use.
• the side walls are folded like an accordion and attached directly to the car roof with their lower edge.
• the lid Since in this - not generic - arrangement the lid is not raised while the vehicle is moving, it cannot be used as a luggage transport container. in the the rest of it is not removable, but firmly connected to the car roof. In addition, it has no floor element, rather the car roof itself is the lower limit.
• DE-OS 38 12 067 describes a roof rack, in particular for cars, in which a rigid box-shaped receptacle is provided with a pot-shaped insert which is displaceable in the longitudinal direction and passes through a recess in the rear wall of the receptacle and between an inner and an outer end position can be pulled out of the receptacle.
• the cup-shaped insert is also made of dimensionally stable material.
• the known roof luggage rack makes the storage volume variable in the longitudinal direction in order to be able to load skis or the like, the air resistance of the overall arrangement is always the same regardless of the loaded luggage or whether there is luggage in the roof rack at all high.
• a sleep attachment for motor vehicles is known from DE-GM 82 11 681, which can be mounted on the vehicle roof. Even with this - not generic - arrangement, it is not provided or possible to transport luggage.
• the sleep attachment is intended only opened and used when the vehicle is stationary. In addition, there is no tensioning of the cover against the floor.
• the cover element can only be pivoted at the front edge relative to the car roof. This is also unsuitable for the transport of luggage, since even relatively small luggage requires the cover element to be pivoted up very far.
• the invention is based on the problem of designing a luggage transport case in such a way that its cross-sectional area, viewed in the direction of travel, can be changed depending on the storage space just required.
• a luggage transport case of the type described in the introduction in which the base element has a base plate, the cover element can be placed on the base element to form a cavity, and the wall element in the empty state of the luggage carry case completely in the cavity between the base element and can be stowed in the cover element.
• the stowage space can thus be adapted to current needs due to its non-rigid wall element.
• the distance between the base element and the cover element can be changed by the non-rigid wall element. The result of this is that, with little storage space required, the distance between the base element and the cover element can be small, as a result of which the cross-sectional area of the luggage transport case in the direction of travel and thus - the total air resistance is small.
• the distance between the base element and the cover element can be increased as a result of the foldable or extendable wall element, which also increases the storage space.
• the luggage transport case according to the invention thus offers the advantage that on the one hand it has a large storage space when required, while in the little or no load state it has a small cross-sectional area in the direction of travel and thus a low overall air resistance.
• the luggage transport case according to the invention has an extremely narrow silhouette in the side view and an optimally small cross-sectional area in the front view. Despite these small dimensions in the empty state, which make it possible to leave the luggage transport case on the vehicle even when it is unladen, without the overall air resistance of the vehicle being substantially increased thereby, the luggage transport case according to the invention offers a storage space volume, if required, that also for transportation large and bulky objects is suitable. The items are safely stored in the luggage bag and protected from wind and moisture.

• the length of the longitudinal slots in the side walls of the two hollow profiles can be made differently, the rear longitudinal slots viewed in the direction of travel being longer than the front longitudinal slots. This has the effect that, in conjunction with a corresponding length of the respective tensioning straps, the cover element can be set further back than at the front, as a result of which a positive effect on the coefficient of drag is achieved even when loaded.
