Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a tilting operation part for raising and lowering the wheel by aircraft-based driving, and a No. 41 ff1lJ grounding float biased toward the grounding side by a coil spring, whose number of cores is maintained almost constant. The coil spring is mechanically interlocked so that it is mechanically interlocked, and the human operating tool is mechanically interlocked so that the coil spring is in a non-acting state or substantially in a non-acting state with respect to the float. Walking in which the human operating tool is mechanically connected to a restraining member that acts as follows 4)), 1.114
Regarding i'i machine.

By changing 1.?J to the coil spring inactive state, the automatic lifting control of the wheels relative to the aircraft due to the swinging of the ground float will be made more sensitive to the aircraft, and the aircraft will be slightly lowered. This allows the aircraft to turn easily while maintaining the ascending attitude side VC and reducing the sliding resistance of each ground leveling float against the mud surface.
Conventionally, the wheel Vf, the lowering operation part and the traction 111 part are connected to the manual operation tool using two rope ears, rods, etc. It was connected.

However, since there are two interlocking systems from the human operating tool, there is a drawback that the structure is complicated.

In view of the above-mentioned conventional situation, it is an object of the present invention to simplify the series III measures from the human operating tool by simple and rational improvements, and to solve the problem of coil spring machines. , even more! The object of the present invention is to make the operating structure more compact.

Features of the present invention: In the walking type 1) item 'f1 machine, the connection between the artificial control unit 1↓ and the operating section 111'J part 1) 11 is inserted into the coil spring, 01 ] Record interlocking part 1'4 K music restraining part shrine is attached to the skewer.

When A is used for multiple purposes, the connection n (1, 1
The drawings can be made into one system, and the operation structure for the operation section and check member can be greatly simplified.

Moreover, that series! Since the IIIJ part is inserted into the coil spring, the continuous WJ parts + and i can be further utilized to maintain the shape of the coil spring when it expands and contracts, improving the biasing function of the coil spring. In addition, compared to the coil spring 1j:l1lh part, the dedicated space for the coil spring can be saved, and overall, the manufacturing and assembly is much easier in both terms of production and economics. It has now been possible to provide a walking type tljt+T machine which has excellent performance, has a compact operating structure, and has excellent self-elevating and lowering control performance of its wheels.

Next, 7i' = t
