Abstract
Abstract The invention is a trailer suitable for hauling fruit bins or the like, pivotally connected to a hitch and supported by an axle assembly which includes an offset cross shaft. An hydraulically actuated cam assembly rotates the cross shaft so that the rear end of the trailer can be lowered to the ground for easy loading and unloading without raising the forward end. The trailer also has a stop mechanism on its rear end which is actuated by the same cam assembly which rotates the axle, so as to automatically place it in operative position when the trailer is raised.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A load hauling apparatus comprising: a load support bed connected at one end to a first ground support means: second ground support means for raising and lowering the other end of said bed to move the bed from a generally horizontal raised position to a tilted lowered position including an axle assembly including axle mounted ground wheels and a rotatable cross shaft supporting said bed, the axis of said cross shaft being offset from the wheel axis, whereby rotation of said cross shaft moves said bed between the raised and covered positions: load restraining means positioned in proximity to said other end of said bed and movable between a released position below the surface thereof and a load restraining position above the surface of said bed: actuator means operatively associated with said second ground support means and connected to move said load restraining means to the load restraining position when the bed is moved to the generally horizontal raised position; and cam means on said cross shaft for contacting said actuator means upon rotation thereof in the direction to move the bed to the horizontal raised position so as to move said load restraining means to the load restraining position.
Claim 2
Dependent Claim
200 words
A load hauling apparatus comprising: a load support bed connected at one end to a first ground support means: second ground support means for raising and lowering the other end of said bed to move the bed from a generally horizontal raised position to a tilted lowered position including an axle assembly including axle mounted ground wheels and a rotatable cross shaft supporting said bed, the axis of said cross shaft being offset from the wheel axis, whereby rotation of said cross shaft moves said bed between the raised and covered positions: load restraining means positioned in proximity to said other end of said bed and movable between a released position below the surface thereof and a load restraining position above the surface of said bed: actuator means operatively associated with said second ground support means and connected to move said load restraining means to the load restraining position when the bed is moved to the generally horizontal raised position; and cam means on said cross shaft for contacting said actuator means upon rotation thereof in the direction to move the bed to the horizontal raised position so as to move said load restraining means to the load restraining position.
Claim 3
Dependent Claim
58 words
The apparatus of claim 1 wherein said load restraining means includes a block mounted to said bed for pivotal movement between said released position and said load restraining position, and said actuator means includes a lever positioned in proximity to said cam means for engagement thereby, and means for coupling said block to said lever for movement therewith.
Claim 4
Dependent Claim
44 words
The apparatus of claim 1 wherein said actuator means includes means for locking said load restraining means in said load restraining position until said bed is moved to the tilted lowered position, and means for biasing said load restraining means toward said released position.
Claim 5
Dependent Claim
228 words
A load hauling trailer comprising: a load support bed: first ground support means connected to a first end of said bed for supporting said first and above ground level; second ground support means for raising and lowering the second end of said bed to move said bed between a generally horizontal raised position where said bed is generally parallel to ground level, and a tilted lowered position where the first end of said bed is in close proximity to ground level including an axle assembly including axle mounted ground wheels and a rotatable cross shaft supporting said bed, the axis of said cross shaft being offset from the wheel axles, whereby rotation of said cross shaft moves said bed between the raised and lowered positions; a block mounted on said bed for movement between a load restraining position in which it extends above said bed and a released position in which it lies below said bed; actuator means operatively associated with said second ground support means and connected to move said block into said load restraining position when said bed is moved into said generally horizontal raised position; and cam means on said cross shaft for contacting said actuator means upon rotation thereof in the direction to move the bed to the horizontal raised position so as to move said load restraining means to the load restraini position.
Claim 6
Dependent Claim
228 words
A load hauling trailer comprising: a load support bed: first ground support means connected to a first end of said bed for supporting said first and above ground level; second ground support means for raising and lowering the second end of said bed to move said bed between a generally horizontal raised position where said bed is generally parallel to ground level, and a tilted lowered position where the first end of said bed is in close proximity to ground level including an axle assembly including axle mounted ground wheels and a rotatable cross shaft supporting said bed, the axis of said cross shaft being offset from the wheel axles, whereby rotation of said cross shaft moves said bed between the raised and lowered positions; a block mounted on said bed for movement between a load restraining position in which it extends above said bed and a released position in which it lies below said bed; actuator means operatively associated with said second ground support means and connected to move said block into said load restraining position when said bed is moved into said generally horizontal raised position; and cam means on said cross shaft for contacting said actuator means upon rotation thereof in the direction to move the bed to the horizontal raised position so as to move said load restraining means to the load restraini position.
Claim 7
Dependent Claim
23 words
The trailer of claim 4 wherein said actuator means includes means to operate said block responsive to the movement of said cross shaft.
Claim 8
Dependent Claim
34 words
The trailer of claim 5 wherein said rotating means includes a cam plate affixed to said cross shaft, and hydraulic actuating means connected to rotate said cam plate, whereby said cross shaft is rotated.
Claim 9
Dependent Claim
45 words
The trailer of claim 6 wherein said means to operate said block includes: lever means positioned in proximity to said cam plate for actuation thereby; and a coupling rod extending between said lever means and said block to move said block with said lever means.
Claim 10
Dependent Claim
16 words
The trailer of claim 4 further comprising means for biasing said block toward said released position.
