Abstract: There is described a rack system for displacing a ladder between a loading/unloading position and a stored position respectively on a side and on a rooftop of the vehicle. The ladder rack system comprises a handle lever by which a user applies an input angular movement. A gear assembly is connected to the handle lever and comprises gears to multiply the input angular movement into an output angular movement greater than the input angular movement. A linking member is pivotably connected to the gear assembly and is for undergoing and transmitting the output angular movement. A sliding arm assembly is to receive the output angular movement from the linking member, thereby being pivoted between the loading/unloading position in which the sliding arm assembly extends substantially vertically on the side of the vehicle and the stored position in which the sliding arm assembly extends substantially parallel to the rooftop.

Abstract: The present invention relates to a ladder rack for holding a ladder, the ladder rack comprising an arm extending longitudinally from a proximal end to a distal end; a slidable member which is slidably mounted on the arm; a first clamp fixed to the arm; a second clamp fixed to the slidable member at a distance from the first clamp; a handle pivotally connected to the distal end of the arm; a pivoting member pivotally connected on one end to the handle and on another end to the slidable member; whereby upon pivoting the handle upwardly, the pivoting member is forced to pivot at both ends thereof and to push on the slidable member, which translates toward the proximal end, reducing the distance between the first clamp and the second clamp.
