<p>A ladder clamping device for a vehicle roof rack where the roof rack includes a pair of spaced apart side rail assemblies held together by a plurality of transversely extending crossbar members and the ladder clamping device includes a pair of ladder clamping arms located proximate front and rear end portions of the ladder rack and a mechanism for simultaneously elevating and lowering the ladder clamping arms to selectively engage and disengage from a pair of rungs of a ladder being transported. The mechanism comprises a longitudinally extending rotatably journaled rod that is coupled by separate articulated linkages to the ladder clamping arms and where the ladder clamping arms are themselves affixed to transversely extending actuator rods that are journaled for rotation about axes offset from crossbar members to which they are affixed.</p> |
