Abstract

1358222 Vehicle roof rack clamp INDUSTRI AB THULE 16 Feb 1972 [16 Feb 1971] 7280/72 Heading B7J [Also in Division E2] A device for securing a luggage carrier on the edge of a car roof comprises a support foot 12 having a support surface 16 intended to be located on the upper edge 17 of a car roof, preferably with the interposition of a plastics insert 18, a tensioning member 13 whose lower edge is turned to form a member 19 for locating under the edge 17, a control arm 14, pivoted some way along its length to the top of the tensioning member 13 and, at its lower end to a holding member 20 slidable in a cut-out portion 21 of the support foot 12, an adjusting device 15, and means for preventing the tensioning member from being displaced from the roof. The adjusting device 15 preferably comprises the holding member 20, a screw, secured to it, whose lower end extends freely through a hole in a support member 22 secured to the support foot 12, and a nut 23 on the screw and bearing against the top of support member 22. As best seen in the closed position of Fig. 2, rotation of the nut varies the distance between the member 19 at the lower end of the tensioning member 13 and the support surface 16 of support foot 12, and thus varies the clamping force exerted by the device. To prevent lateral displacement of tensioning member 13, 19, from the car roof in the position of Fig. 2, a tongue 25 extending downwards from support member 22 is slidable in a slot 24 in the tensioning member. As an alternative, the arrangement of Fig. 3 may be adopted. The tensioning member 13, 19, forms a protective hood over the adjusting device 15 in the closed position. The device is released by swinging the control arm 14 downwards.
