Combination airplane tow bar, platform and step stool structure for use in attending to small aircraft. The platform includes an upper deck member having depending side flanges inset from each side edge thereof with each flange extending beyond the end edge of the deck member and terminating in a rounded apertured end. Leg assemblies are pivoted to the ends of the flanges for movement between a position perpendicular to the deck member for use of the device as a seat, step stool, elevated platform or the like and a position extending longitudinally outwardly of the deck member for use of the device as an airplane tow bar. One of the leg assemblies includes a latch structure for connection with an aircraft to enable the aircraft to be towed. The latch structure may include a spring latch depending on the aircraft attachment. Both leg assemblies can be pivoted into overlying relation to the deck member for compact storage and when folded, the device forms an effective wheel chock for the aircraft.

A combination airplane tow bar, seat, and step stool structure comprising a platform formed by a generally flat plate, a pair of leg assemblies, means pivotally connecting the leg assemblies to opposite peripheral portions of the platform for engagement of an upper end portion of each leg assembly with an undersurface of the platform when the leg assemblies are oriented in perpendicular depending relation to the platform so as to support the platform in elevated position for use as a seat or step stool, and for pivoting of the leg assemblies from said perpendicular relation to an overlying position to an upper surface of the platform to enable storage of the structure in a compact position, and means on one of said leg assemblies for connection with an airplane for use as a tow bar when the leg assemblies are pivoted to a position generally parallel to the platform and extending outwardly therefrom.
