In the case of a roofrack the transverse supports (1) comprise a customary supporting profile (4) which is covered by a drop-shaped cover (5) in order to reduce the aerodynamic drag. This cover (5) can be completely or partially removed in order to be able to fasten structural parts (8) on the supporting profile (4). <IMAGE>
The invention relates to a roof rack for Motor vehicles, the cross member to reduce the Flow resistance are drop-shaped.
Such a roof rack is the subject of US-PS 24 75 903.
In contrast to the roof rack according to the above US-PS 24 75 903 have currently in common use Lichen, releasable roof load to be attached to the roof sluggish cross member, which as a mostly rectangular support profile are formed. This can help on the cross carriers, such as bicycle carriers or ski holder can be attached very well. A disadvantage of such cross members are relatively high wind resistance stood, which led to an undesirable increase in fuel leads to consumption and wind noise when driving gently. These disadvantages have been particularly significant meaning, because often the Cross members remain on the vehicle even when the Roof rack is not required. A reshaping of usual roof rack such that their cross beams obtained drop-shaped cross-section would be too high Lead costs and make it necessary, all of them Modify body parts accordingly.
The invention has for its object a roof to design load carriers of the type mentioned at the beginning, that customary construction parts can be used for him.
This object is achieved in that the cross beams from a usual support profile and one teardrop-shaped cladding releasably attached to it consist.
With this design, you can use conventional cross beams lazily provided with a covering to stream them training in a way that is easy on the mind. Should on the cross members Attachment parts are attached, then you can the Verklei Simply remove the manure so that the body parts can be Liche way can be attached. In such cases are the wind noise caused by the cross beams and their flow resistance is less significant since the transported objects a much higher Cause wind resistance. Thanks to the invention you can however, if the cross beams are not used, they are attached bring the manure into a streamlined state.
The cladding is particularly simple in construction stalten, if it from a the support profile with an off there is a flush encompassing profile body and if the recess is covered by a locking part bar is formed, which are two opposite th of the recess releasably connects.
The locking part is simple and convenient to handle when it is on a long side of the off Take out hinged flap trained det, which is on the opposite side locking feet for locking into a snap-in receptacle of the profile body Has.
Another very simple, alternative version form of the locking part is that it is a is separate component from the profile body, which at the long sides locking feet for locking in a locking has the profile body.
The paneling on the Cross member held when according to another Ausgestal tion of the invention of the profile body on both sides its recess facing each other, at least partially wise over the support profile, through the Verrie gelungteil has interconnectable webs and if on the side of the recess facing away from the webs Profile body is designed to be bendable.
If structural parts are attached to the cross beams, then you can be on both sides of the body parts sensitive crossmember areas streamlined the by covering the invention of several Side-by-side brackets to be attached to the support profile sections exist.
It is important for the fairing that it is the flow resistance of the mostly rectangular cross member profile belittles. However, it can also be used for other effects te can be achieved, for example, that the Ver clothing has the shape of a wing profile. If such a wing profile exactly the opposite of trains an airplane, then can arise through that de air flow can be achieved, for example, that high driving speed when lifting the vehicle is counteracted. The cladding can thus Take over the function of a rear spoiler.
The invention allows numerous embodiments. To further clarification of their basic principle will follow subsequently referred to the drawing. This shows in
Fig. 1 is a perspective view of a dung OF INVENTION designed according to the cross-member with lateral support legs,
Fig. 2 shows one of Fig. 1 of an second embodiment of a clothing Ver the roof rack,
Fig. 3 is a perspective view of the cross sectional profile of the ver with the lining provided for the cross member,
Fig. 4 is a marked in Fig. 3 with IV A detail on an enlarged scale.
Fig. 1 shows a roof rack, a cross member 1 , which connects two conventional support feet 2, 3 together. The cross member 1 consists of a customary, cross-sectionally rectangular support profile 4 and a casing 5 attached to it, which has a teardrop-shaped or wing-like cross section to reduce the air resistance. If structural parts, not shown, are to be fastened on the cross member 1 in FIG. 1, the covering 5 must first be removed.
Fig. 2 shows that the panel 5 can also consist of several ren panel sections 6, 7 . Between these cladding sections 6, 7 , the support profile 4 is therefore unclad, so that there a mounting part 8 , for example a trough of a bicycle holder and the corresponding holding arm, can be attached to it.
The design of the casing 5 is shown in FIG. 3. It consists essentially of a profiled element 9 that engages with a recess 10 on the support profile 4, and a locking member 11, which recess the off covers 10 and two opposed sides of the recess 10 releasably connects. In the embodiment shown, the profile body 9 has on its upper side two superposed, the upper side of the support profile 4 partially covering webs 12, 13 on which the locking part 11 is attached. In order to be able to slide the profile body 9 onto the support profile 5 when the locking part 1 has been removed, kinks 14, 15 are provided at the lower corners of the recess 10 in the profile body 9 , which are each formed by a channel-shaped recess in the profile body 9 .
Illustrates the Fig. 4, as the locking member 11 is detachably connected to the profile body 9. It is known that the profile body 9 has a snap-in receptacle 16 formed by a cut longitudinal groove, into which the locking part 11 is locked with snap-in feet 17 . In this way, the locking part 11 can be locked on its two longitudinal sides with the profile body 9 . However, it is also possible to connect the locking part 11 in a hinge-like manner to the profile body 9 on one side of the recess 10 and to provide the latching feet on the opposite side.
Both the profile body 9 and the locking part 11 can be made of PVC as an inexpensive extruded profile.
