Abstract
A tug device for moving small aircraft having front wheels. A portable drill is connected to a drive wheel and a frame is attached to the wheel. The device is steerable, having a wheel mounted on a vertical set of pins such that the wheel is pivotable about the axis of the pins to permit turning the wheel on that axis and steering the tug while operating the drive mechanism.
Claims24
In a tug device for moving small aircraft on the ground and having at least one front wheel, said device including a frame, a handle for connecting a drive wheel for engagement with the ground the drive wheel being thereby driven by a drill having a variable output and connected to said drive wheel by a drive shaft, said frame having an engaging member for attachment to said aircraft, the improvement comprising:
- a vertically aligned mounting bracket on said drive wheel positioning said drive wheel for rotation about a vertical axis generally perpendicular to the ground;
- support structure on said frame for engaging said mounting bracket and supporting said drive wheel on said frame for angular movement about said vertical axis;
- a fastener for engaging said mounting bracket on said drive wheel and said handle for moving said bracket about said vertical axis to thereby turn said drive wheel and permit said device to steer as well as move said aircraft.
In a tug device for moving small aircraft on the ground and having at least one front wheel, said device including a frame, a handle for connecting a drive wheel for engagement with the ground the drive wheel being thereby driven by a drill having a variable output and connected to said drive wheel by a drive shaft, said frame having an engaging member for attachment to said aircraft, the improvement comprising:
- vertically aligned mounting bracket means on said drive wheel for positioning said drive wheel for rotation about a vertical axis generally perpendicular to the ground;
- support structure means on said frame for engaging said mounting bracket means and supporting said drive wheel on said frame for angular movement about said vertical axis;
- fastener means for engaging said mounting bracket means on said drive wheel and said handle for moving said bracket means about said vertical axis to thereby turn said drive wheel and permit said device to steer as well as move said aircraft.
A tug device for moving small aircraft on the ground and having at least one front wheel, said device comprising:
- a frame;
- a drive wheel mounted on said frame for engagement with the ground;
- a drill having a variable output;
- a handle having a drive shaft connecting said drive wheel to said drill to permit said drill to drive said drive wheel;
- an engaging member on said frame for attachment to said aircraft;
- a vertically aligned mounting bracket on said drive wheel positioning said drive wheel for rotation about a vertical axis generally perpendicular to the ground;
- a support structure on said frame for engaging said mounting bracket and supporting said drive wheel on said frame for angular movement about said vertical axis;
- and
- a fastener for engaging said mounting bracket on said drive wheel and said handle for moving said bracket about said vertical axis to thereby turn said drive wheel and permit said device to steer as well as move said aircraft.
A tug device for moving small aircraft on the ground and having at least one front wheel, said device comprising:
- frame means for supporting said device;
- drive wheel means mounted on said frame for engagement with the ground for driving said device;
- drill means having a variable output for driving said drive wheel means;
- handle and drive shaft means connecting said drive wheel means to said drill means for permitting said drill means to drive said drive wheel means;
- engagement means on said frame means for attachment of said device to said aircraft;
- vertically aligned mounting bracket means on said drive wheel means for positioning said drive wheel means for rotation about a vertical axis generally perpendicular to the ground;
- support structure means on said frame means for engaging said mounting bracket means and supporting said drive wheel means on said frame means for angular movement about said vertical axis;
- and
- fastener means for engaging said mounting bracket means on said drive wheel means and said handle means for moving said bracket means about said vertical axis to thereby turn said drive wheel and permit said device to steer as well as move said aircraft.
