State of the art A load carrier foot of the type described above is already known from German patent DE 3405357. However, the disadvantage of this earlier type of foot is that the contact faces incorporated in the design do not always ensure that the gripping means maintains its grip when the clamping plate is tightened against the load carrier foot. As a result, the user may, on observing this situation, attempt to tighten the clamping plate further, possibly causing the foot to damage the vehicle roof or, if the situation is not observed, causing the load carrier foot to lose grip its completely, with the possibility of catastrophic consequences since the load carrier may then be thrown from the vehicle roof.

Brief description of invention The present invention overcomes the aforementioned disadvantages by means of a load carrier foot of the type described in the introduction, which is characterised in that the pivot pin is

pivotable connected to the foot part and that the clamping plate and the load carrier foot are each provided with contact faces, which are located above the pivot pin and which interact in a locking manner and which, further prevent the clamping plate gripping means from being twisted out of engagement when the clamping plate is tightened.

Brief description of figures A preferred embodiment of a load carrier foot in accordance with the present invention will hereinafter be described with reference to the appended figures, of which: Fig. 1 is a schematic view of a vehicle with a roof-mounted load carrier; Fig. 2 is a view showing a roof edge area with a load carrier foot in accordance with the present invention mounted on it; Fig. 3 is a view corresponding to Fig. 2 seen from the side, with the interior of the foot exposed; Fig. 4 is a view in which the inside of the load carrier foot is made visible and in which part of the clamping plate is omitted to show the invention more clearly; Fig. 5 is a detail view from which the interaction between the clamping plate and the foot part is clearly seen and Fig. 6 is a view corresponding to Fig. 5 showing the load carrier foot in a non tightened position.

Preferred embodiment Fig. 1 shows a vehicle 1 with a load carrier bar 3 mounted on the roof 2 by means of load carrier feet 4 to the roof edge areas 5.

Fig. 2 shows a roof edge area 5 with a load carrier foot 4 provided with a foot part 6, to the upper end 7 of which is connected a load carrier bar 3. The lower end 8 of the foot part rests against a roof edge area 5 and a clamping plate 9 attached to the foot part grips a body fold 11 located under the roof edge area 5 by means of a gripping means 10. The body fold 11 may be a door or window opening. The figure furthermore shows a cover 12, whose sole function is to

cover the mechanism which is housed in the foot part and will be described below, and also provides the load carrier foot with an attractive appearance.

Figs. 3 and 4 are detail views of the load carrier foot with the cover 12 omitted. The figures show that the foot part 6 comprises a base part 13, which rests on the roof edge area 5. The base part may preferably be made of a plastic material to prevent it from damaging the vehicle paintwork. A housing part 14 is permanently attached to the base part 13 with fastening devices 15 and 16 respectively. The housing part supports a load carrier bar 3, which is permanently attached to the housing part by means of screws 17. The housing part 6 incorporates walls 18 and 19, in which channels 20 and 21 respectively are provided. A pivot pin 22 is seated in the channels 20 and 21 by means of journals 23 and 24, which extend into the respective channels and are free to turn. The clamping plate 9 is attached to the pivot pin 22 by means of open slots 25 in the clamping plate, only one of which is visible in Fig. 4, enclosing the pivot pin journals 23 and 24 respectively. This arrangement permits the clamping plate to be moved upward and downward in the direction indicated by the double arrow P in Fig. 4. A tightening arrangement 26, consisting of a screw 27 threaded into a tapped hole 28 in the pivot pin 22, and with a head bearing on the clamping plate 9, enables the clamping plate and gripping means to be moved, in a manner familiar to one skilled in the art, upward towards the foot part 6, whereby the gripping means grips the body fold 1 l and tightens the load carrier foot 3 against the roof edge area 5. The clamping plate is provided with lower contact faces 30 located under the pivot pin 22 and upper contact faces 31 located above the pivot pin 22. Although only one of these is visible in Fig. 4, it will easily be understood that the clamping plate is provided with a corresponding face in the area hidden by the wall 19. The walls 18 and 19 are provided respectively with lower contact faces 32, only one of which is visible in the figure, which interact with the lower contact faces 30 and upper contact faces 33, which faces, in turn, interact with the contact faces 31.

Fig. 5 shows the interaction of the contact faces. The figure shows the foot part mounted on a roof edge area 5. The clamping plate 9 grips a body fold 11 with its gripping means 10 and the clamping plate 9 is tightened in an upward direction in the direction indicated by the double

arrow P. The interaction which occurs between the lower contact faces 30 and 32 and the upper contact faces 31 and 33 respectively prevents the clamping plate from turning about the pivot pin 22 in the clockwise direction, which direction is indicated by the arrow U, ensuring that the gripping means 10 does not lose its grip on the body fold 11.

In Fig. 6, the clamping plate has been move downward in the direction indicated by the double arrow P, in which position the contact faces have been separated and the clamping plate is free to turn in the clockwise direction, facilitating both simple mounting and removal of the load carrier foot.
