Abstract
The invention provides a trailer including a wheeled chassis which is connected to a load support frame by an articulated linkage whereby the frame can be moved vertically in relation to the chassis. A manually actuated lever enables the frame to be vertically moved between a lowered, unloading position and an upper, traveling position. The linkage enables the loading frame to be angled forwardly and downwardly in the traveling position whereby a catamaran or other load mounted thereon provides a stabilizing aero-foil effect during forward movement of the trailer.
Claims10
A trailer comprising a wheeled chassis and a load support frame having a rear end and a forward end, said wheeled chassis being connected to the support frame by a linkage for moving the frame vertically in relation to the wheeled chassis, wherein said linkage includes a rear strut pivotally mounted to the chassis and pivotally mounted to the rear end of the support frame, a forward strut pivotally mounted to the chassis and pivotally mounted to the forward end of the support frame, the rear strut being longer than the forward strut and the pivotal mountings of the rear strut and the forward strut to the chassis being substantially in the plane of the chassis, lever means mounted to and extending from the forward strut for moving the support frame vertically in relation to the chassis between a raised position and lowered position and locking means for locking the lever means in at least the raised position and retaining the support frame in a raised position in relation to the chassis;
- said rear strut and said forward strut cooperating with said frame and said chassis to maintain the pivotal mounting of the rear strut to the chassis forward of the pivotal mounting of the rear strut to the support frame between the raised and lowered positions.
