CROSSBAR CLAMP DEVICES
Racks are used to carry cargo on top of vehicles. Racks include crossbars and assemblies configured to secure specific cargo items to the crossbars. Clamps for connecting cargo-specific assemblies to the crossbars, include first and second jaws, and an adjustment device for selectively controlling horizontal relative movement between the jaws.
1 . An apparatus for securing cargo to a crossbar on top of a vehicle comprising:
a cargo supporting device configured to contact and secure cargo on a pair of crossbars on top of a vehicle, the cargo supporting device having a track defining a horizontal linear clamping axis parallel to a direction of vehicle travel, and a first jaw member descending from a bottom side of the cargo supporting device;
a second jaw member configured to move along the track of the cargo supporting device for clamping a crossbar cooperatively with the first jaw member; and
an actuator connected to the second jaw member and configured to drive movement of the second jaw member along the internal track, the actuator including a threaded shaft extending generally along the clamping axis and engaging corresponding internal threads of the second jaw member such that rotation of the threaded shaft causes the first and second jaw members to clamp a crossbar.
