[Industrial applications]

本考案の運搬車は、荷物の運搬に使用し、特に階段の昇降に優れている。 INDUSTRIAL APPLICABILITY The transport vehicle of the present invention is used for transporting luggage, and is particularly excellent for climbing stairs.

[Prior Art]

従来、荷物の運搬には四輪の運搬車が知られている。この運搬車は安定していて荷物のを積み重ねて運搬するには都合がいい。しかし、階段の昇降用には適していない。２輪の運搬車は音が静かでスムーズな運搬ができる。しかし、やはり階段の昇降には適していない。階段の昇降用として開発された四つ足の運搬車もあるが、いずれもスムーズな階段の昇降に適していない。 2. Description of the Related Art Conventionally, four-wheeled vehicles are known for carrying luggage. This carrier is stable and convenient for stacking and carrying luggage. However, it is not suitable for climbing stairs. The two-wheeled carrier is quiet and can be transported smoothly. However, it is still not suitable for climbing stairs. There are four-legged vehicles that were developed for climbing stairs, but none of them are suitable for smooth stair climbing.

[Problems to be solved by the device]

階段は場所により、段差の高さが異なり、すべてに適合するのは困難である。段差が低ければ、大きな車輪では階段を引き上げることができるが、段差が高ければ、車輪は階段に当たり、次の段に引き上げることができない。このように、階段の昇降には困難な問題がある。 Stairs have different heights depending on the location, and it is difficult to fit all. If the step is low, large wheels can raise the stairs, but if the step is high, the wheels hit the stairs and cannot move to the next step. Thus, raising and lowering stairs poses a difficult problem.

【０００４】[0004]

[Means for Solving the Problems]

従来の２輪車の車軸の先端に付いている車輪を小さくし、さらにその内側に位置して、同一車軸に３方向に出た足を付け、各足の先端に車輪を付ける。この３方向の足の間隔だけ、空間を飛ぶことになる。このため、階段の下の段と上の段との壁に足の車輪が突き当たると、中央の車輪に回転が移行し、次いで、次の足の車輪に回転が移行する。 The wheel attached to the tip of the axle of a conventional two-wheeled vehicle is made smaller, and the wheel is attached to the inner side of the axle. You will fly in space by the distance between your feet in these three directions. Therefore, when the foot wheel hits the wall between the lower and upper steps of the stairs, the rotation shifts to the wheel in the center and then to the wheel of the next leg.

【０００５】[0005]

[Action]

順番に回転を移行して、運搬車を移動させるので、階段の昇降がスムーズにできる。また、平地でも、安定して走行できる。 Since the rotation shifts in order and the carrier is moved, the stairs can be raised and lowered smoothly. In addition, it can run stably even on flat ground.

【Example】

実施例について図面を参照して説明する Embodiments will be described with reference to the drawings.

【図１】は平面図である。FIG. 1 is a plan view.

【図２】は側面図である。運搬車１の車軸２に中央の車輪３が付いている。別に、３方向に出た足４に車輪５、６、７が付いている。階段の壁に車輪５が突き当たると、回転は車輪３に移行する。次いで、車輪６に移行する。このようにして、FIG. 2 is a side view. A central wheel 3 is attached to the axle 2 of the carrier 1. Separately, wheels 5, 6, and 7 are attached to a foot 4 extending in three directions. When the wheel 5 hits the wall of the stairs, the rotation transfers to the wheel 3. Next, the wheels 6 are transferred. In this way

【図３】の使用例のように運搬車１は階段８を上ることができる。As in the use example of FIG. 3, the carrier 1 can climb stairs 8.

【０００７】[0007]

[Effect of the device]

荷物の運搬が楽になり、労働時間の短縮になる。製造コストも従来の運搬車と大差無い価格でできる。 Luggage transportation becomes easier and working hours are shortened. It can be manufactured at a price that is not much different from conventional trucks.
