Abstract
Abstract A road vehicle adapted to carry a container or to act as a tipping wagon comprising an auxiliary chassis adapted to carry the container and pivotally secured to the main chassis of the vehicle around an axis extending across the rear end of the latter. A single jack system controls selectively a lever adapted to draw a container lying on the ground to the rear of the vehicle onto the auxiliary chassis and to shift the container back onto the ground, and the tilting of the auxiliary chassis when the vehicle is to serve as a tipping wagon.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
In a road vehicle adapted to removably carry a load and having a main chassis, an improvement comprising a controlling mechanism including an auxiliary load-carrying chassis extending over the main chassis and pivotally connected to the main chassis around an axis extending transversely across the rear end of said main chassis, a lever adapted to engage at one end the front end of the load to be carried by the main chassis and pivotally secured through its other end to the auxiliary chassis, single control means controlling selectively the pivotal movement of the auxiliary chassis around its axis and the pivotal movement of the lever and therethrough the shifting of the load between the ground and the upper surface of the auxiliary chassis and means for locking selectively the lever on the auxiliary chassis and the auxiliary chassis on the main chassis.
Claim 2
Dependent Claim
142 words
In a road vehicle adapted to removably carry a load and having a main chassis, an improvement comprising a controlling mechanism including an auxiliary load-carrying chassis extending over the main chassis and pivotally connected to the main chassis around an axis extending transversely across the rear end of said main chassis, a lever adapted to engage at one end the front end of the load to be carried by the main chassis and pivotally secured through its other end to the auxiliary chassis, single control means controlling selectively the pivotal movement of the auxiliary chassis around its axis and the pivotal movement of the lever and therethrough the shifting of the load between the ground and the upper surface of the auxiliary chassis and means for locking selectively the lever on the auxiliary chassis and the auxiliary chassis on the main chassis.
Claim 3
Dependent Claim
41 words
A controlling mechanism as claimed in claim 1, wherein the lever is pivotally secured to the auxiliary chassis through pivotal means adapted to slide longitudinally on said auxiliary chassis over a predetermined length under the action of the single control means.
Claim 4
Dependent Claim
62 words
A controlling mechanism as claimed in claim 1, wherein the single control means includes a jack pivotally connected to the lever at one end and to the main chassis at its other end, one of the pivotal connections respectively between the lever and the auxiliary chassis and the jack with the main chassis being adapted to slide longitudinally of the corresponding chassis.
Claim 5
Dependent Claim
67 words
A controlling mechanism as claimed in claim 1, wherein the lever is pivotally secured to the auxiliary chassis through pivotal means adapted to slide longitudinally on said auxiliary chassis under the action of the single control means, said single control means including a jack pivotally connected to the lever at one end and the other end of which is adapted to slide longitudinally along the main chassis.
Claim 6
Dependent Claim
105 words
A controlling mechanism as claimed in claim 1, wherein the single control means includes a jack pivotally connected to the lever at one end at a point near the pivotal connection between the lever and the auxiliary chassis, the mechanism including furthermore at least one link extending parallel to the longitudinal axis of the main chassis, said link having end portions which are pivotally secured respectively to the other end of the jack and to the auxiliary chassis, and means constraining the outer end of said link beyond its point of connection with the jack to run longitudinally over the surface of the main chassis.
Claim 7
Dependent Claim
52 words
A controlling Mechanism as claimed in claim 1, wherein the lever is square-shaped and includes a first arm adapted to engage the major part of the height of the load to be carried and a second arm adapted to engage a large fraction of the length of the underside of said load.
Claim 8
Dependent Claim
26 words
A controlling mechanism as claimed in claim 1, wherein the first-mentioned end of the lever and the cooperating end of the load include interengageable hooking means.
