Abstract: An assembly and method is disclosed for moving a load into and out of an enclosure such as the enclosure of a van. The assembly may include an upright shaft rotatably mounted within a side portion of the enclosure. A boom assembly extends from the shaft. The boom assembly includes a beam to which an arm is pivotally mounted. An extension member is also pivotally attached to the arm such that as the shaft rotates the angular orientation of the arm with respect to the beam is controlled by the extension member whereby the load may be moved in a substantially straight direction into or out of the enclosure in response to rotation of the shaft. A length of the extension member may be adjusted to move the line of movement of the load closer or nearer to the shaft. A motorized winch is preferably mounted to the end of the arm to lift the load.

Abstract: A universal ladder lock and method for locking a ladder to a vehicular rack utilizes a mounting frame that may be secured to existing vehicular racks. Affixed to the mounting frame is a lock housing which slidably and rotatably supports an elongate lock arm. A hook is provided on one end of the elongate lock arm for hooking around a portion of one or more ladders. One or more stop elements are secured to the elongate lock arm for limiting longitudinal movement of the elongate lock arm. The stop housing provides one or more lock member supports which may be utilized to receive a locking pin, or a padlock. The locking pin or padlock prevents movement of the stop element affixing the elongate lock arm in a position with the hook around the ladder to thereby lock the ladder with respect to the vehicular rack.
