Abstract

The vane (1) can be placed on the car roof rack or on the car bodywork and its position (4) and angle of attack (3) can be varied to suit the load. The vane can be aerodynamically shaped and reduces drag on roof mounted luggage. The height of the top edge can be varied to that of the load carried, to cover the load. This also reduces the need to hold the load onto the carrier by excessive force.

Description

La présente Lnvention a pour objet un dispositif qui rédult le résistance de l'air provoquée par des objets placés sur un porte bogage ou palerle situé sur le toit d'une voiture en sorche. The present Lnvention relates to a device which reduces the resistance of the air caused by objects placed on a boge or pallet rack located on the roof of a sorche car.

Une galerie chargée rend plus difficile la pénétration de la voiture dans l'air. A loaded gallery makes it more difficult for the car to penetrate the air.

Le dispositif est remorquable en ce qu'il permet à l'oir de s'échapper et de ne pas vente buter sur les objets, provoquant einsi une réslstonce a l'avancement du véhicule. The device is towable in that it allows the air to escape and not to collide with objects, thus causing a reslstonce to the advancement of the vehicle.

Surtout quand il y o du vent et face ou vénlcule, alors que ce dernier revêt des formes cérodunalques, on annule en partle les effets de non résistance à l'air de l'aérodunamlsme en plaçant sur le tolt dus véhicule des objets présentant des surfaces verticales dans le sens du mouvement provoquent ainsi une résistance à l'air. Cette résistance à l'air est très importante et omène comme on le soit à une consommation supplémentaire de carburant. Especially when there is wind and face or vénlcule, while the latter takes on cerodunal forms, we cancel in part the effects of non resistance to air of aerodunamlsm by placing on the tolt of the vehicle objects with vertical surfaces in the direction of movement thus cause resistance to air. This air resistance is very important and leads, as is the case with additional fuel consumption.

Il existe blen entendu des procédé permettant de réduire les effets de la réalstance de l'oir sur les colases de comlons et sur les caravanes mals ils sont lnapplicobles sur portes bogages. Of course, there are methods which make it possible to reduce the effects of the realism of having it on the colases of comlons and on unhealthy caravans they are not applicable on buggy doors.

le procédé présente les avantages sulvants :
Fable prix et facile à adapter sur tous les portes bagages et galerles
En supprimant la résistance de l'air, il permet d'économiser du carburant.the process has the following advantages:
Low price and easy to adapt to all luggage racks and gallerries
By removing air resistance, it saves fuel.

En éliminont les pressions variables de l'oir sur les objets placés sur le porte bogages il permet une meilleure stabillité du véhicule et une meins grande varlation de la pression des pneus zur le sol, ce qui ne peut qu'oméllorer encore la consommation de carburant. By eliminating the variable pressures of having it on the objects placed on the boge rack it allows a better stability of the vehicle and a lesser variation of the tire pressure on the ground, which can only further improve fuel consumption .

En évitant à l'oir d'entrer en contact avec les objets placés sur le porte bogages, on empêche les insectes, la boue et les projections d'eau de les soullex. By avoiding having it come into contact with the objects placed on the boge rack, it prevents insects, mud and water splashes from the soullex.

En opportant de la stabilité au véhicule, le procédé donne plus de sécurité à la conduite de celui-ci. By providing stability to the vehicle, the process gives more safety in driving it.

Une forme d'exécution de l'Invention est décrite cl-oprès à titre indicatif et nullement limitotif en se référant aux dessins annexés. An embodiment of the invention is described cl-oprès by way of indication and in no way limiting with reference to the accompanying drawings.

La figure 1 est une vue de côté du tolt du véhicule avec la golerie et le dispositif. Figure 1 is a side view of the vehicle tolt with the golerie and the device.

Le dispositif (1) est fixé sur la golerla (2) il s'articule (3) et peut être ouancé ou reculé (4) selon le ho9uteur des objets ofin de réduire au maximum la résistance de l'air. The device (1) is fixed on the golerla (2) it is articulated (3) and can be opened or moved back (4) according to the ho9utor of the objects ofin to reduce to the maximum the resistance of the air.

Sur la figure 2, la lorgeur du dispositif peut également selon la lorgeur des objets être modifiée ofin de bien isoler ces dernlers de la résistance de l' aLr  In FIG. 2, the rigidity of the device can also, depending on the rigidity of the objects, be modified in order to properly isolate these latter from the resistance of the aLr
