Aircraft loading apparatus
View Patent ↗Aircraft loading apparatus includes a frame removably attachable to an aircraft (e.g. a helicopter). The frame is constructed for assembly and disassembly in a transitional position and includes a pair of raising and lowering mechanisms. The mechanisms include a pair of belts with free ends attachable to form a sling and connected for simultaneous extension or retraction of equal lengths of each belt. In operation, the frame is attached to the aircraft adjacent an area at which an article (e.g. an auxiliary fuel tank) is to be connected. The article is positioned under the frame and the belts are extended to form a sling around the article. The mechanisms are activated to simultaneously retract equal lengths of each belt to raise the article into a connecting position, the article is connected, and the frame is disassembled into a removable configuration and removed from the aircraft.
1. Aircraft loading apparatus comprising:
a frame removably attachable to an aircraft, the frame being constructed for assembly and disassembly in one of an attached position and a transitional position into a removable configuration, the frame includes side members separated by cross-members, the cross-members removably attached to the side members, the frame is removably attachable to the aircraft by means of fingers attached to the side members in a horizontally extending orientation; and
a raising and lowering mechanism affixed to the frame, the mechanism including a pair of belts with free ends of belts being attachable to form a sling, the pair of belts and mechanism being connected for simultaneous extension or retraction of equal lengths of each belt.
2. Aircraft loading apparatus as claimed in claim 1 wherein the side members separated by cross-members form a substantially rectangular frame.
3. Aircraft loading apparatus as claimed in claim 1 wherein the removable configuration includes the side members being separated into individually removable portions.
4. Aircraft loading apparatus as claimed in claim 3 wherein the frame is constructed for assembly and disassembly in the transitional position.
5. Aircraft loading apparatus as claimed in claim 1 wherein the frame, including the fingers, is designed to mate with auxiliary fuel tank mounting structure on a helicopter.
6. Aircraft loading apparatus as claimed in claim 1 wherein the pair of belts and the raising and lowering mechanism are connected by a drivable pulley for the simultaneous extension or retraction of equal lengths of each belt.
7. Aircraft loading apparatus comprising:
an elongated frame removably attachable to an aircraft, the frame being constructed for assembly and disassembly in a transitional position into individually removable portions, the elongated frame includes side members separated by cross-members, the cross-members removably attached to the side members, the frame is removably attachable to the aircraft by means of fingers attached to the side members in a horizontally extending orientation; and
a pair of raising and lowering mechanisms, one each affixed adjacent opposite ends of the frame, each mechanism including a pair of belts with free ends of each pair of belts being attachable to form a sling, each pair of belts and associated mechanism being connected for simultaneous extension or retraction of equal lengths of each belt in each pair.
8. Aircraft loading apparatus as claimed in claim 7 wherein the side members separated by cross-members form a substantially rectangular frame.
9. Aircraft loading apparatus as claimed in claim 7 wherein the frame, including the fingers, is designed to mate with auxiliary fuel tank mounting structure on a helicopter.
10. Aircraft loading apparatus as claimed in claim 7 wherein the pair of belts and the raising and lowering mechanism are connected by a drivable pulley for the simultaneous extension or retraction of equal lengths of each belt.
