High angle link hinge
First Claim
1. In an apparatus having a first member rotatably connected at a joint to a second member, a linkage for transmitting torque comprising:
- said second member having two first parallel spaced side walls, each said side wall having access openings;
said first member having two second parallel spaced side walls rotatably mounted outboard of said first sidewalls of said second member;
an input link having one end rotatably mounted to said second member between said first sidewalls and a second end;
means for applying a moment to said input link about said one end of said input link;
an output link having one end rotatably mounted to said joint and a second end, said output link being so operatively connected to said first member that said first member moves with said output link;
a coupler link having a first end connected to said second end of said input link and a second end connected to said second end of said output link, said coupler link being pivotally mounted through said access openings in said second member to said first member;
the length of said input link being greater than the length of said output link so that rotation of said input link about its one end causes said coupler link to rotate said output link about its ones end through a greater angle of rotation than that of said input link.

Abstract
A linkage for transmitting torque includes a stationary member, a movable member rotatably mounted to the stationary member, an input link having one end rotatably mounted to the stationary member and a second end connected to a linear actuator and a coupler link. The coupler link is connected to the second end of an output link, preferably integral to the movable member. The moment applied to the input link by the linear actuator is transferred through the coupler link to the output link, or movable member. The angle of rotation of the output link is greater than the angle of rotation of the input link.

11. A linkage for transmitting torque comprising:
-
a stationary member having two first parallel spaced side walls, each said first side wall having access openings; a movable member having two second parallel spaced side walls, each second side wall being rotatably mounted to the opposing outboard side of one of said first side walls of said stationary member; an input link having one end rotatably mounted to said stationary member between said first side walls and a second end; a coupler link between said first side walls having a first end pivotally mounted to said second end of said input link and a second end pivotally mounted through said access openings to said movable member; and means for applying a moment about the rotatable mounting of said one end of said input link to said stationary member, said moment being transferred through said coupler link to said movable member. - View Dependent Claims (12, 13, 14)
