Abstract:
A ladder rack assembly for a work vehicle has a stationary bed for attachment to the roof thereof. A pair of parallel, spaced apart rails has guides thereon that extend from the rails' first ends toward, but short their second ends. Rollers on side edges of a load support member ride on the bed rails. When the rollers are constrained by the guides, only translation of the load support member takes place. Upon exit of the rollers from the rear ends of the guides, both translation and rotation of the load support member can occur. A control arm is pivotally joined at one end to the stationary bed. Its free end has cam actuated latch pin assemblies attached to it that co-act with cams on the stationary bed during rearward displacement of the load support member to latch the load support member to the control arm whereby further rearward movement of the load support member causes it to tilt to a somewhat vertical position.

Claim (Index 15):
The apparatus of  claim 14  wherein the rotary to linear drive mechanism comprises:\n a motor disposed in a housing; \n a drive sprocket journaled for rotation in the housing and driven by the motor; \n a plurality of idler sprockets journaled for rotation in the housing; \n a chain comprising a plurality of links surrounding said drive sprocket and said plurality of idler sprockets where at least two of said idler sprockets are mounted to define a rectilinear flight extending parallel and adjacent to the underside of the load support members; and \n a plurality of regularly spaced brackets affixed to the underside of the load support member, each of the brackets including a slot having an open end and where selected ones of said links of the chain have laterally extending pins where the length of chain between adjacent pins corresponds to the distance between the slots on adjacent ones of said plurality of brackets such that, as the chain is being driven, one of the pins will enter the slot on one of the plurality of brackets as another of the pins exits the slot on another of the plurality of brackets.
