Folding gooseneck trailer with positioning system

A folding gooseneck trailer, comprising:

• a main bed having ground engaging wheels at one end portion and frame means defining at least a partial substantially vertical rectangular passage in said main bed at the other end portion;
• a loading bed having a king pin mounted on one end portion for adapting said loading bed to be connected with the fifth wheel of a tractor, the other end portion of said loading bed being adjacent to said main bed;
• a pair of parallel links each of which is pivotally connected at opposite ends to the other end portions of said main and loading beds so that said loading bed can be raised and lowered with respect to said main bed;
• an elongated element having a cross-section smaller than that of said rectangular passage in said main bed so that said element is movable in and constrained to movement in opposite longitudinal directions with respect to said element, said elongated element terminating at the bottom portion in a ground engageable foot;
• a clevis plate connected to the bottom portion of said elongated element;
• and
• a power actuated cylinder and piston assembly connected between said loading bed and clevis whereby when said piston is extended said elongated element is extended from said passage in said main bed so that said foot is in ground engagement with said other end portion of said main bed being then held in a raised position with respect to said ground by said cylinder and piston assembly and said parallel links, and whereby said piston is retracted said elongated element is withdrawn into said passage in said main bed and said loading bed is pivoted with respect to said main bed at said pair of parallel links so that said loading bed can assume a lowered position to act as a ramp for loading and unloading from said main bed.

In a folding gooseneck trailer having a loading bed pivotally connected to a main bed by a connecting link, a positioning system, comprising:

• frame means in the main bed of the trailer defining a substantially vertical channel;
• slidable means received in said channel of said frame means, said slidable means terminating at one end portion in a foot and having connecting means thereon;
• and
• an extendible power actuator connected between the loading bed of the trailer and said connecting means of said slidable means for controlling the relative movements of said main bed, loading bed and slidable means whereby said foot on said slidable means may be extended and retracted with respect to said frame means of said main bed by said power actuator and said loading bed may be pivoted with respect to said main bed by said power actuator and said connecting link.
