ABSTRACT:
A van platform including a housing for installation upon the floor of a van or truck. The housing includes a first floor located over the van floor to define a storage space therebelow, in which space a ramp is located. The ramp is arranged to be moved out of its retracted position in the housing space to an extended, inclined ramp-functioning position. The ramp includes rollers to facilitate movement of the ramp to the extended position. Upwardly inclined blocks are located within the housing and each includes an indentation for the reception of an associated roller as the ramp reaches a desired position adjacent the top surface of the first floor. The housing includes first locking means to lock the rollers within the associated indentations when the ramp is extended and second means for locking the ramp within the retracted position. The second means is in the form of a releasable handle which is also used to effect the extension of the ramp out of the housing.
