Abstract
A cross support for extending between the roof rails on a motor vehicle roof, and having a detachable clamping device for clamping to the railing tube. The clamping device includes a stationary resting jaw and a clamping jaw movable toward the resting jaw. The clamping jaw has a yoke for engaging the railing tube and has an attack surface on the opposite side of the pivot from the yoke. A swing lever is pivotably supported on the cross support and is swingable between positions where it locks the clamping jaw in the clamping position and where it releases the clamping jaw. The clamping jaw and the swing lever are on respective spaced apart pivots.
Claims20
A cross support for cooperating with a pair of roof rails on the roof of a motor vehicle, the cross support comprising:
- a support for extending between said rails;
- and
- a clamping device disposed on the support for attaching the support to at least one of the roof rails, the clamping device including:
- a base member;
- a resting jaw disposed on the base member for clamping against one side of the at least one rail;
- a clamping jaw having upper and lower arms and supported on the base member pivotally between the upper and lower arms such that the lower arm is movable relative to the resting jaw, the upper arm including an attack surface, and the lower arm of the clamping jaw including a yoke for engaging a second side of the at least one rail and being opposed to the resting jaw, such that clamping by the resting jaw and the yoke of the clamping jaw onto the at least one rail holds the support to the rail;
- and
- a swing lever swingably mounted on the base member and swingable between a first position in which the swing lever engages the upper arm of the clamping jaw whereby the yoke of the clamping jaw pivotally engages the second side of the at least one rail and is held thereto and a second position in which the yoke is not held against the at least one rail, by relative movement of the swing lever with respect to the clamping jaw for locking the yoke on the lower arm of the clamping jaw in a clamped position against the at least one rail.
A clamping device adapted to be disposed on a cross support for clamping the cross support to a roof rail on the roof of a motor vehicle, the clamping device comprising:
- a base member;
- a resting jaw disposed on the base member for clamping against one side of the rail;
- a clamping jaw having upper and lower arms and pivotally supported by the base member between the upper and lower arms such that the lower arm is movable relative to the resting jaw, the upper arm including an attack surface, and the lower arm of the clamping jaw including a yoke for engaging a second side of the rail, such that clamping by the resting jaw and the yoke of the clamping jaw onto the rail holds the support to the rail;
- and
- a swing lever swingably mounted on the base member and swingable between a first position in which the swing lever engages the upper arm of the clamping jaw whereby the yoke of the clamping jaw pivotally engages the rail and is held thereto, and a second position in which the yoke is not held against the rail, the swing lever including a clamping projection thereon for engaging the attack surface of the upper arm of the clamping jaw and sliding along the attack surface as the swing lever is swung between the positions thereof, such that the clamping projection engages with the attack surface after the swing lever has been swung to the first position thereof for locking the yoke on the lower arm of the clamping jaw in a clamped position against the rail.
