Abstract
Abstract A boat auxiliary motor support, comprising a base, a bracket and two levers between which is mounted a control system comprising one cylinder, one piston and one hollow piston rod containing a control rod free to slide axially. The interior of the cylinder is divided up by a floating piston into a chamber filled with gas and forming a gas sprint and two chambers filled with oil and separated by the piston. The control rod rests against a valve mounted in the piston, that allows the oil to flow from one chamber to the other through a duct. A control system is mounted at the free end of the control rod to open the valve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A boat auxiliary motor support consisting of a parallelogram, comprising a base to be mounted on the transom of the boat, a bracket to support the auxiliary motor and two levers hinging on the base and the bracket and between which is mounted a control system comprising at least one cylinder, one piston and one hollow piston rod containing a control rod free to slide axially, characterized in that the interior of the cylinder is divided up by a floating piston into one chamber filled with gas and forming a gas spring and two chambers filled with oil and separated by the piston, in that the control rod rests against a valve mounted in the piston, that allows the oil to flow from one chamber to the other through a duct and in that a control system is mounted at the free end of the control rod to open the valve, so that the parallelogram can be moved and, when the valve is closed, the parallelogram is locked in the required position.
Claim 2
Dependent Claim
172 words
A boat auxiliary motor support consisting of a parallelogram, comprising a base to be mounted on the transom of the boat, a bracket to support the auxiliary motor and two levers hinging on the base and the bracket and between which is mounted a control system comprising at least one cylinder, one piston and one hollow piston rod containing a control rod free to slide axially, characterized in that the interior of the cylinder is divided up by a floating piston into one chamber filled with gas and forming a gas spring and two chambers filled with oil and separated by the piston, in that the control rod rests against a valve mounted in the piston, that allows the oil to flow from one chamber to the other through a duct and in that a control system is mounted at the free end of the control rod to open the valve, so that the parallelogram can be moved and, when the valve is closed, the parallelogram is locked in the required position.
Claim 3
Dependent Claim
38 words
A support as claimed in claim 1, characterized in that the control unit is equipped with a handle which locks the parallelogram in any required position and which has a flat section acting as a cam against rod.
Claim 4
Dependent Claim
38 words
A support as claimed in claim 1, characterized in that the base and/or the bracket have holes in them that permit the mounting to be fitted to boats the transoms of which are at different angles of tilt.
Claim 5
Dependent Claim
31 words
A support as claimed in claim 1, characterized in that the cylinder is closed off by a plug in which there is a valve permitting the gas pressure to be altered.
