Abstract
A two level trailer is shown in which the upper deck may be conveniently tilted down to load or unload cargo. An upper deck is supported on four posts, one mounted at each corner of the lower deck. The front posts are fixed in place but the rear posts are pivotally mounted to the lower deck so as to have forward or rearward freedom of movement. The upper deck is pivotally mounted to the top ends of the front posts. Sleeves mounted on a cross member at the rear edge of the upper deck slide up and down the rear posts as the deck is raised or lowered. The cross member has some rotational freedom of movement relative to the upper deck to prevent binding with the rear posts when the upper deck is moved up or down.
Claims9
A dual level trailer having a fixed position lower deck and a tiltable upper deck that comprises:
- the lower deck being of generally rectangular outline having forward and rearward ends, the forward end being adjacent a hitch;
- upright posts located at each corner of the lower deck to support the upper deck, the pair of posts located at the forward end of the lower deck being fixed in position, the pair of posts located at the rear end of the lower deck being pivotally attached to the lower deck so as to have limited forward and rearward freedom of movement;
- the forward end of the upper deck being pivotally attached to the upper ends of the forward posts to enable the upper deck to tilt down for cargo loading or be raised to travel position;
- post enclosing sleeves attached at rear corners of the upper deck, the sleeves being slidable up or down the rear posts, the sleeves having limited rotation relative to the upper deck sufficient to prevent binding when the upper deck is moved relative to the rear posts;
- and
- elevating means to raise and lower the upper deck.
A dual level trailer having a lower fixed position deck and a tiltable upper deck that comprises:
- the lower deck being of generally rectangular outline having forward and rearward ends, the forward end being adjacent a hitch;
- upright posts located at each comer of the lower deck to support the upper deck, the pair of posts located at the forward end of the lower deck being fixed in position, the pair of posts located at the rear end of the lower deck being pivotally attached to the lower deck so as to have forward and rearward freedom of movement;
- the upper deck having longitudinal and transverse structural support members, the forward end of the upper deck having a support member pivotally attached to the upper ends of the forward posts to enable the upper deck to tilt down for cargo loading or be raised to travel position;
- a tube means providing structural support passing transversely through the rearward portion of the longitudinal upper deck structural support members, said tube means and support members having relative rotational freedom;
- post enclosing sleeves attached to outboard ends of the tube means, the sleeves positioned to slide up and down over the rear posts, and
- elevating means to raise and lower the upper deck.
