Abstract

A universally fitting and reusable grip assembly for non-destructive and removable attachment to a pedal, such as a rudder pedal of an aircraft or flight simulator. The grip assembly includes two hingedly connected clamps whose frame members are fitted, respectively, over the top edge and under the bottom edge of the pedal, with clamp screws threadedly adjusted to secure the clamp frames to the pedal; and, an artificial pedal member which incorporates a load cell and which is attached to the lower disposed one of the two clamp frame members. The load cell measures the force applied to the pedal, such as by a pilot's foot or other sources, including a remotely located, interconnected, conventional load applying device. If the grip assembly is used on a rudder pedal of an aircraft or flight simulator, the grip assembly need not be removed in order to fly the aircraft (or flight simulator) in the conventional manner.

Claims5

Dependent claims

A universal, reusable, grip assembly for non-destructive and removable attachment to a pedal, comprising:

a. a first clamp means for being removably attached to an upper portion of said pedal, wherein said means includes:
a first frame member which overhangs said upper portion of said pedal;
and
a first movable means for securing said first frame to said pedal, wherein this means includes a first clamp screw member threadedly movable in said first frame member and also in securing contact with a rear surface of said pedal, with said first movable securing means operably associated with said first frame member;
b. a second clamp means for being removably attached to a lower portion of said pedal, wherein this means includes:
a second frame member hingedly connected to said first frame member and disposed in an underslung position relative to said lower portion of said pedal;
and
a second movable means for securing said second frame member to said pedal, wherein this means includes a second clamp screw member threadedly movable in said second frame member and also in securing contact with a rear surface of said pedal, with said second movable securing means operably associated with said second frame member;
and
c. means, operably associated with said first and said second clamp means and attached to a front surface of said second clamp means for measuring the amount of a load applied to said first and said second clamp means and to said pedal, and for measuring any resultant displacement of said pedal, wherein said applied load and pedal displacement measuring means includes:
an artificial pedal member attached to a front surface of said second frame member;
and
a transducer means attached to said artificial pedal member, with said transducer means operably connected to a load and displacement measuring device.

10 more elements

A universal, reusable, grip assembly for non-destructive removable attachment to a rudder pedal of an aircraft/aircraft flight simulator, said rudder grip assembly comprising:

a. a first clamp means for being removably attached to an upper portion of said rudder pedal, wherein said means includes:
a first frame member which overhangs said upper portion of said rudder pedal;
and
a first movable means for securing said first frame member to said rudder pedal, wherein this means includes a first clamp screw member threadedly movable in said first frame member and also in securing contact with a rear surface of said rudder pedal, with said first movable securing means operably associated with said first frame member;
and
b. a second clamp means for being removably attached to a lower portion of said rudder pedal, wherein this means includes:
a second frame member hingedly connected to said first frame member and disposed in an underslung position relative to said lower portion of said rudder pedal;
and
a second movable means for securing said second frame member to said rudder pedal, wherein this means includes a second clamp screw member threadedly movable in said second frame member and also in securing contact with a rear surface of said rudder pedal, with said second movable securing means operably associated with said second frame member;
whereby the rudder pedal of said aircraft/aircraft flight simulator to which said rudder pedal grip is removably attached can be used conventionally to operate said aircraft/aircraft flight simulator without the removal of said rudder pedal grip assembly.
