Abstract
The trailer bed plate (3) is tipped by the towing vehicle moving backwards. The tow bar (1) is hinged to a sliding hinge (2) disposed on the underside of the bed plate, and connected via at least one connecting rod (4) to wheel-supporting frame (5) which is hinged to the rear of the bed plate at (11). When the sliding hinge is released to slide rearwardly, the rod-frame-bed triangle changes shape at the same time as the trailer tips. The trailer may then be locked in this position and tilted back about the wheels so that its bed plate occupies a higher horizontal plane than that occupied in the running position. The trailer then constitutes a table, or work bench.
Claims8
A tipper trailer comprising:
- a bed plate having a front and a rear;
- a wheel-supporting frame including two ground-engaging wheels defining a horizontal transverse wheel axis, said frame being hinged to said bed plate proximate the rear end of said bed plate about a first hinge axis parallel to said wheel axis;
- a longitudinally directed slide disposed under said bed plate and rigidly connected thereto slidingly receivable of a sliding hinge;
- a sliding hinge received within said longitudinally directed slide, said sliding hinge slideable between a forward position proximate said front of said bed plate and a rearward position remote from said front of said bed plate;
- a tow bar having a front end suitable for coupling to a towing vehicle, and having a rear end directly coupled to said sliding hinge about a second hinge axis parallel to said wheel axis, said tow bar being pivotable about said second hinge axis relative to said bed plate;
- releasable locking means for locking said tow bar to said bed plate to prevent said tow bar for rotating relative thereto;
- and
- at least one connecting rod having a first end pivotally coupled to said sliding hinge about said second hinge axis and having a second end pivotally coupled to said wheel-supporting frame about a third hinge axis parallel to said wheel axis.
