Abstract
Abstract A simulator mechanism capable of operating in three degrees of freedom is described comprising a base (14) having a fixed plane, a simulator plane (12) and three independent extendible actuators (16, 18 and 20) capable of changing the simulator operating plane, three actuators (16, 18 and 20) being pivotally coupled with universal freedom at or around, a substantially single point (C), each actuator (16, 18 and 20) being pivotally coupled to points (J, E, and F) on the simulator plane (12), each point (J, E and F) being spaced apart from the other actuator coupling points on the same plane A restrainer means is provided to prevent motion in the yaw, surge and sway axes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
80 words
A simulator mechanism capable of operating in three degrees of freedom, including a base having a fixed plane, a simulator operating plane and three independent extendible actuators capable of changing the operating plane, characterized in that: the three actuators are pivotally coupled with universal freedom at a generally single on the base plane, said single point comprising closely aligned connection points for the three actuators; each actuators is pivotally coupled at a spaced apart point on the simulator operating plane.
Claim 2
Dependent Claim
80 words
A simulator mechanism capable of operating in three degrees of freedom, including a base having a fixed plane, a simulator operating plane and three independent extendible actuators capable of changing the operating plane, characterized in that: the three actuators are pivotally coupled with universal freedom at a generally single on the base plane, said single point comprising closely aligned connection points for the three actuators; each actuators is pivotally coupled at a spaced apart point on the simulator operating plane.
Claim 3
Dependent Claim
19 words
A simulator mechanism as claimed in claim 1 wherein the simulator operating plane has a simulator capsule attached thereto.
Claim 4
Dependent Claim
42 words
A simulator mechanism as claimed in claims 1 or 2 wherein the actuators are coupled to operate in heave, about the pitch and roll axes and where the mechanism has restraining means to prevent unwanted motion in yaw, surge and sway axes.
Claim 5
Dependent Claim
23 words
A simulator mechanism as claimed in claim 3 wherein the restraining means are A-frames or equivalents thereto having pivotal axes parallel and horizontal.
Claim 6
Dependent Claim
14 words
A simulator mechanism as claimed in claim 3 wherein there are two restraining means.
Claim 7
Dependent Claim
36 words
A simulator mechanism as claimed in claim 5 wherein one of the two restraining means is attached via a sliding bearing to the simulator operating plane, the direction of the slide being along the surge axis.
Claim 8
Dependent Claim
43 words
A simulator mechanism as claimed in claim 4 wherein the actuators are hydraulic rams having extendible pistons, pneumatic rams having extendible pistons, electric actuators, a rack and pinion operated by electric motor or a ball and nut operable on a rotatable screw rod.
Claim 9
Dependent Claim
15 words
A simulator mechanism as claimed in claim 7 wherein the actuator is a hydraulic ram.
