A roll-out deck apparatus is fitted to a pick-up truck, for loading/unloading a snowmobile etc. The deck may be tilted about a hinge pivot at the rear edge of the truck, whereby the deck forms a ramp, up and down which the snowmobile may be manipulated. The apparatus includes an electric winch, located at the front end of the deck, for raising and lowering the deck, about the hinge pivot. A sub-frame of the apparatus is directly hinged to the rear edge of the truck bed; the sub-frame can undergo pivoting or tilting movement about the hinge pivot. A deck-frame is telescopable with respect to the sub-frame, but is otherwise locked to the sub-frame, whereby when the sub-frame tilts the deck-frame tilts in unison.

[ I claim:] [1.] Deck apparatus for use with a truck, wherein:the apparatus includes a sub-frame, and includes a means for mounting the sub-frame to a floor of the truck, by way of a pivot hinge;the pivot hinge is located at or close to the rear of the sub-frame, the axis of the hinge being horizontal and lateral with respect to the truck;the structural arrangement of the pivot hinge is such that the sub-frame can pivot between a stowed position in which the sub-frame lies flat and horizontal, and a tilted position, in which the sub-frame is tilted, whereby a front portion of the sub-frame is raised above a rear portion of the sub-frame;the apparatus includes a deck-frame, and includes a guide means;the guide means is so structured as to be effective, in operation of the apparatus, to guide the deck-frame for movement relative to the sub-frame, being in-out telescoping movement in the longitudinal direction relative to the truck;the guide means is so structured as to be effective to constrain the deck-frame against all other modes of movement of the deck-frame other than the said telescoping relative to the sub-frame, whereby, when the sub-frame undergoes tilting movement about the hinge pivot, the deck-frame follows that same tilting movement;the deck-frame includes left and right elongate longitudinal structural deck-frame members, secured underneath a deck panel;the sub-frame includes left and right elongate longitudinal structural sub-frame members, and the sub-frame members lie in a parallel-alongside relationship with the deck-frame members;the guide means includes profiled tracks formed in the left and right sub-frame members, being a left profiled track in the left sub-frame member and a right profiled track in the right sub-frame member;the guide means includes left and right front rollers, which are bearinged to the deck-frame at the front of the deck-frame, respectively to the left and right of the deck-frame;in respect of the left-front-roller, the roller is formed with a circumferential groove, the left-front-roller being provided with surfaces that define left and right side walls of the groove;the left profiled track, being the track formed in the left sub-frame member, includes a promontory, the promontory being provided with surfaces that define left and right side walls of the promontory;the left and right side walls of the promontory of the left track are complementary to the left and right side walls of the groove in the left roller, to the extent that, when the left roller runs on the left track, the left roller is constrained, by the engagement of the left and right side walls of the groove with the left and right side walls of the promontories, against both left and right movement laterally away from the left track;in respect of the right-front-roller, the roller is formed with a circumferential groove, the right-front-roller being provided with surfaces that define left and right side walls of the groove;the right profiled track, being the track formed in the right sub-frame member, includes a promontory, the promontory being provided with surfaces that define left and right side walls of the promontory;the left and right side walls of the promontory of the right track are complementary to the left and right side walls of the groove in the right roller, to the extent that, when the right roller runs on the right track, the right roller is constrained, by the engagement of the left and right side walls of the groove with the left and right side walls of the promontories, against both left and right movement laterally away from the right track;the left profiled track is channel-shaped, having upper and lower flanges, and the promontory is formed in the lower flange thereof, and a corresponding promontory is formed in the upper flange thereof.the right profiled track is channel-shaped, having upper and lower flanges, and the promontory is formed in the lower flange thereof, and a corresponding promontory is formed in the upper flange thereof.
