Abstract
A cross bar used in roof luggage carriers for vehicles including a shaft having first and second threaded segments which are threaded in opposite directions relative to one another. A first pair of gripping jaws includes first gripping jaws which are threadedly engaged to the shaft. The first gripping jaw is threadedly engaged to the first threaded portion of the shaft and the second gripping jaw is threadedly engaged to the second threaded portion of the shaft. When the shaft is rotated, the first and second jaws move relative to one another thereby gripping or releasing a side rail placed there between. The gripping jaws are adapted to slide on the shaft thereby allowing them to float independent of a second pair of gripping jaws located along the same shaft. Thus, the cross bar of the present invention can be used to accommodate vehicles having non-parallel side rails. Also, the cross bar is adjusted from one side of the vehicle thereby avoiding the inconvenience of having the user access both sides of the vehicles to adjust the cross rail.
