Cargo carrier

The present invention concerns a cargo or bicycle carrier (1), the carrier, when in use, being arranged on and supported by a towbar (19,20), mounted on the car (2), and which carrier comprises a support platform (3) or the like for the bicycles, a clamping device (18) attached to the platform for clamping the platform to a towbar ball (20), the clamping device comprising two clamping members (28,29), having each a ball cup (32,38), designed to partly fit against the respective of two mainly opposite parts of the towbar ball (20), one of the clamping members (29) being movably arranged in the clamping device (18), and a locking member (441,42), pivotably arranged to, when actuated, force the movably arranged clamping member (29) towards the other clamping member (28) in order to clamp the towbar ball (20). The invention is that the locking member (41,42) is pivotable around a locking member axis (24) and comprises an actuating part (41), protruding from the locking member axis (24) and having a cam surface (43), facing the movably arranged clamping member (29), and a lever (42), attached to the actuating part (41), for pivoting the actuating part around the locking member axis (24) to eather of an end locking position or a position away therefrom, that the movably arranged clamping member (29) has a supporting member (33), which is carrying the ball cup (38) and is extending from and pivotably arranged with a clamping member axis (34), spaced from the ball cup (38), that the supporting member has a sliding surface (44), facing the actuating part cam (41), whereby the sliding surface (44) and the actuating part cam surface (43) are arranged to cooperate in pivoting the movably arranged clamping member (29) around its axis (34) from a loose hanging position towards the other clamping member (28) to a clamping position where the ball cups (32,38) are clamping the ball (20) under tension, and that the sliding surface (44), the actuating part cam surface (43) and the lever (42) are arranged in the way that the actuating part cam surface (43) is near or at a position where the sliding surface normal (44n) through the contact point between the sliding and cam surfaces (44 and 43) intersects the locking member axis (24), i.e. at a locking position, when the lever (42) is at its end locking position.
