Abstract
An anti-theft device for an aircraft includes first and second U-shaped members one of which has tubular legs telescopically receiving arms of the other and one of the arms of which extends through a passage in sleeve and control post components in the cockpit of an aircraft to lock the aileron and elevator components of the aircraft against displacement relative to the aircraft wings and stabilizer, respectively. A key or combination type lock releasably holds the anti-theft device in its mounted condition.
Claims28
An anti-theft device in combination with an aircraft having elevators and ailerons, a cockpit, and an elevator and aileron control post in said cockpit, said combination comprising:
- said control post extending along an axis;
- a sleeve fixed in said cockpit coaxial with said axis and supporting said control post;
- said control post being moveable along said axis in directions forwardly and rearwardly for controlling said elevators and rotatable about said axis for controlling said ailerons, said elevators and ailerons having neutral positions for streamlining the aircraft for air flow across the elevators and ailerons, said sleeve and control post having openings therethrough transverse to said axis and aligned when said elevators and ailerons are in said neutral positions to provide a locking passage having opposite ends on opposite sides of said sleeve;
- said anti-theft device having mounted and unmounted positions for attachment to said locking passage and including (a) a first member having an arm extending through said locking passage in said mounted position, said arm in said mounted position having a first end outwardly of one end of said locking passage and a second end outwardly of the other end of said locking passage with said first end limiting displacement of said arm toward said other end of said locking passage;
- (b) a second member including a leg slidably interengaged with said second end of said arm in said mounted position and limiting displacement of said arm toward said one end of said locking passage;
- and (c) a lock having locked and unlocked positions precluding and allowing separation of said arm from said leg, respectively.
An anti-theft device in combination with an aircraft having elevators and ailerons, a cockpit, and an elevator and aileron control post in said cockpit, said combination comprising:
- said control post extending along an axis;
- a sleeve fixed in said cockpit coaxial with said axis and supporting said control post;
- said control post being moveable along said axis in directions forwardly and rearwardly for controlling said elevators and rotatable about said axis for controlling said ailerons, said elevators and ailerons having neutral positions for streamlining the aircraft for air flow across the elevators and ailerons, said sleeve and control post having openings therethrough transverse to said axis and aligned when said elevators and ailerons are in said neutral positions to provide a locking passage having opposite ends on opposite sides of said sleeve;
- said anti-theft device having mounted and unmounted positions for attachment to said locking passage and including a first U-shaped member having parallel arms and a first bight therebetween, one of said arms in said mounted position extending through said locking passage and having an end outwardly of said locking passage;
- a second U-shaped member having tubular legs and a second bight therebetween, said legs in said mounted position slidably receiving said arms;
- said first and second members being relatively displaceable between first and second positions with said arms being in said legs in said first position and at least said one arm being separated from the corresponding leg in said second position whereby said one arm can be withdrawn from said locking passage, and a lock for releasably interengaging said first and second members in said first position.
