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 1):
An apparatus for loading and unloading a load onto and from a roof of a vehicle comprising:\n a) a stationary bed adapted to be affixed to a roof of a vehicle, said stationary bed including a pair of rectilinear rails of a length corresponding to a length dimension of the vehicle's roof and held in parallel, spaced-apart relation by at least one transversely extending cross member; b) a pair of elongate guide members joined individually to the pair of rails and extending from a front end portion of the rails to rear ends, the length of the guide members being less than the length of the rails; c) a load support member having guide rollers affixed thereto adapted to ride on the rails of the stationary bed, the rollers on the load support member cooperating with the guide members to constrain the load support member to translation motion along the rails without rotation until the guide rollers are able to exit the rear ends of the guide members; d) a pair of roller-mounted slides affixed to the opposed side edges of the load support member, the roller-mounted slides being pivotally coupled to rear end portions of the pair of rails of the stationary bed whereby the load support member may be simultaneously translated with respect to the pair of roller-mounted slides and rotated once the guide rollers disengage from the rear ends of the guide members.
