Abstract
A ladder rack for pickup trucks mounted in a detachable manner along one side of truck box. A pair of stanchions each having upper ends provided with arms for ladder support. Brackets attach to the truck box side wall in parallel therewith. Posts on each bracket as well as sockets defined by the brackets receive a weldment at each stanchion lower end the weldments having keyhole openings for post reception and pins for insertion into the bracket sockets. A flexible lock automatically engages a post on the stanchion to prevent accidental upward displacement of the stanchion during truck travel.
 
Claims
Having thus described the invention, what is desired to be secured in a Letters Patent is:

1. A ladder rack for temporary attachment to a pickup truck box side wall, said rack comprising,

stanchions each having a horizontal support terminating in a distal end,

a weldment at the lower end of each of said stanchions and having first and second members perpendicular to one another,

bracket means including horizontal and vertical components for supported engagement with a side wall of the truck box, means for securing said bracket to the truck box side wall, and

locking means carried by said bracket and said weldment to retain the latter in juxtaposition with the bracket in a removable manner.



Description
BACKGROUND OF THE PRESENT INVENTION

The present invention pertains generally to ladder racks for trucks for transporting ladders above a pickup truck box.

In wide use today are ladder racks disposed above truck boxes. Such ladder racks have at least four supports permanently attached to the corners of the truck box. Vehicle usefulness is hindered to the extent that present ladder racks are heavy to reduce operating efficiency of the truck and secondly do not permit large bulky items to be carried in the truck box. Accordingly, it is desirable to have a ladder rack which is readily removable from the truck box.

SUMMARY OF THE INVENTION

The present invention is embodied in a ladder rack having removable front and rear stanchions with arms on which ladders may be transported.

The stanchions are equipped at their lower ends with weldments which are engageable with truck box mounted brackets. The stanchions are of a size and weight to enable installation and removal by one person without involved effort. The weldments, in conjunction with the brackets, support the stanchions against vertical as well as lateral loads. Further, a locking device prevents stanchion movement in response to negative gravity loads. Such a device may include a clip which, in its normal position, abuts a bracket mounted post. Release of the safety device is manually accomplished. Provision is made for use of the present rack on both single and double wall truck boxes i.e., with truck boxes having planar or irregular inner wall surfaces.
