Abstract
Abstract A connecting bar is provided for extending between the combined rudder and wheel brake controlling pedals of an aircraft and includes a centrally disposed rearwardly and upwardly inclined control arm or handle portion. The opposite ends of the bar are connected to the associated combined rudder and wheel brake controlling pedals in a manner enabling lateral deflection of the upper end of the control arm or handle portion to actuate the rudder controlling movement of the corresponding pedal, upward displacement of the control arm or handle portion to effect wheel brake application movement of both rudder pedals, and simultaneous upward and lateral deflection of the control arm or handle portion to effect rudder actuation and wheel brake application movement of the corresponding rudder pedal. The structure by which the opposite ends of the bar are connected to the associated pedals enables the pedal controlling structure to be readily removed from the associated aircraft, the pedal controlling structure being specifically designed for use by pilots unable to properly actuate rudder and/or rudder and brake controlling pedals with their feet.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
In combination with aircraft controls of the type including a pair of horizontally transversely spaced apart side by side right and left fore and aft shiftable rudder controlling foot pedals, a hand control member including a connecting member extending between said pedals, support means supporting spaced portions of said connecting member from said pedals for angular displacement of said spaced portions, and thus said connecting member, relative to said pedals about upstanding axes, and a control arm portion connected rigidly to and extending rearwardly and upwardly from said connecting member in a direction generally transverse to a line extending between said pedals, the free end of said control arm portion being adapted to be grasped and horizontally laterally displaced by the operator of the associated aircraft.
Claim 2
Dependent Claim
126 words
In combination with aircraft controls of the type including a pair of horizontally transversely spaced apart side by side right and left fore and aft shiftable rudder controlling foot pedals, a hand control member including a connecting member extending between said pedals, support means supporting spaced portions of said connecting member from said pedals for angular displacement of said spaced portions, and thus said connecting member, relative to said pedals about upstanding axes, and a control arm portion connected rigidly to and extending rearwardly and upwardly from said connecting member in a direction generally transverse to a line extending between said pedals, the free end of said control arm portion being adapted to be grasped and horizontally laterally displaced by the operator of the associated aircraft.
Claim 3
Dependent Claim
152 words
The combination of claim 1 wherein said support means also includes means supporting said spaced portions of said connecting member from said pedals for angular displacement of said connecting member relative to pedals about substantially aligned axes extending between said spaced portions, said pedals being supported for independent oscillation about horizontal transverse axes between wheel brake applied and wheel brake off positions, and means operatively connecting said spaced portions of said connecting member and the corresponding pedals for selectively shifting both pedals to the brake applied positions thereof upon upward displacement of the rear portion of said control arm portion when the control arm portion is in a transversely centered position and independent shifting of each brake pedal in response to combined upward and lateral displacement of the rear portion of said control arm portion in the lateral direction corresponding to the rudder pedal to be shifted to the brake applied position.
Claim 4
Dependent Claim
17 words
The combination of claim 1 wherein said control arm portion includes a laterally offset upper end portion.
Claim 5
Dependent Claim
50 words
The combination of claim 1 including a handle defining ring supported from the free end portion of said control arm portion for oscillation relative to the control arm portion about an axis disposed, generally, in a diametric plane of said ring and at right angles relative to said support arm.
Claim 6
Dependent Claim
160 words
In combination with aircraft controls of the type including a pair of horizontally transversely spaced apart side by side right and left fore and aft shiftable rudder controlling foot pedals, and also supported for independent oscillation about horizontal transverse axes between wheel brake applied and wheel brake off positions an elongated connecting member extending between said pedals and having the forward end of a rearwardly and upwardly inclined control arm supported therefrom intermediate the opposite end portions of said connecting member, said control arm having a free end adapted to be horizontally, laterally displaced by an operator of the aircraft, a pair of elongated connecting elements first means connecting one pair of corresponding ends of said connecting elements to corresponding end portions of said connecting member for at least limited pivotal movement of the connecting member relative to said elements about upstanding axes and second means rigidly anchoring the other pair of corresponding ends of said elements to said pedals.
Claim 7
Dependent Claim
160 words
In combination with aircraft controls of the type including a pair of horizontally transversely spaced apart side by side right and left fore and aft shiftable rudder controlling foot pedals, and also supported for independent oscillation about horizontal transverse axes between wheel brake applied and wheel brake off positions an elongated connecting member extending between said pedals and having the forward end of a rearwardly and upwardly inclined control arm supported therefrom intermediate the opposite end portions of said connecting member, said control arm having a free end adapted to be horizontally, laterally displaced by an operator of the aircraft, a pair of elongated connecting elements first means connecting one pair of corresponding ends of said connecting elements to corresponding end portions of said connecting member for at least limited pivotal movement of the connecting member relative to said elements about upstanding axes and second means rigidly anchoring the other pair of corresponding ends of said elements to said pedals.
Claim 8
Dependent Claim
22 words
The combination of claim 5 wherein said connecting member is disposed to the rear of the upper end portions of said pedals.
Claim 9
Dependent Claim
65 words
The combination of claim 5 wherein said pedals are also supported for independent oscillation about horizontal transverse axes between brake applied and brake off positions, said first means including means also supporting said one pair of corresponding ends of said elements from said end portions of said connecting member for at least limited oscillation relative thereto about pivot axes extending longitudinally of said connecting member.
Claim 10
Dependent Claim
27 words
The combination of claim 5 wherein said first means includes means swivelly connecting said one pair of corresponding ends to said end portions of said connecting member.
