〔産業上の利用分野〕
この考案は、手押式の運搬車に関するものであ
る。[Detailed description of the invention] [Industrial application field] This invention relates to a hand-pushed transport vehicle.
手押式運搬車の車輪は、前端両側に旋回式が後
端両側に旋回しない固定式が用いられている。
The wheels of the hand-pushed transport vehicle are swivel types on both sides of the front end, and fixed types that do not rotate on both sides of the rear end.
運搬車を方向転換する場合ハンドルを把持して
いる両手の転換方向側片方を方向転換中心となる
よう引き寄せ、残る片方を押し出すことになる。
When changing the direction of a transport vehicle, one of the hands on the direction of change of both hands holding the handle is pulled towards the center of the change of direction, and the other hand is pushed out.
このような方向転換によると、ハンドルに作用
させる押す力は、片方の手のみとなるので、運搬
車に積み込んである品物の重量が大きい場合強力
に押しても容易に方向転換することができず、手
助けを必要とする問題があつた。 According to this type of direction change, the pushing force applied to the handle is limited to only one hand, so if the weight of the items loaded in the transport vehicle is large, the direction cannot be easily changed even if pushed forcefully. I have a problem that I need help with.
上記の問題点を解決するために、この考案は台

車輪と旋回後車輪とを連結装置を介し連結して構
成したものである。
In order to solve the above problems, this invention provides a front turning wheel and a rear turning wheel on both sides of the front end and rear end of the lower surface of the base plate, respectively, and when the front turning wheel turns in the turning direction, the rear turning wheel The front turning wheel and the rear turning wheel on both sides are connected via a coupling device so that the turning wheel rotates in conjunction with the front turning wheel in the opposite direction, and the turning angle is larger than that of the front turning wheel. .
運搬車の方向転換にともない旋回前車輪が転換
方向に旋回する。
As the transport vehicle changes direction, the front wheels turn in the direction of change.
このとき、旋回前車輪の旋回にともない連結装
置を介し旋回後車輪を前記旋回前車輪の反対方向
に旋回させる。 At this time, as the front wheel turns, the rear wheel turns in the opposite direction to the front wheel via the coupling device.
図において、１は手押しハンドル２を有する台

向に連動して旋回し、かつ旋回角度が旋回前車輪
３，３′よりも大きくなるよう連結装置５，５′を
介し連結されている。 Furthermore, when the front turning wheels 3, 3' turn in the turning direction, the turning front wheels 3, 4, and the remaining turning front wheels 3', 4' turn in the turning direction. ' are connected via coupling devices 5, 5' so that they turn in conjunction with the front wheels 3, 3' in the opposite direction, and the turning angle is larger than that of the front wheels 3, 3'.
上記の連結装置５，５′は、図示の場合フオー

にともないロツド７をスライドさせて旋回後車輪
４，４′を旋回させるようにしたが、その他の方
法によつて連動させるようにしてもよい。 In the illustrated case, the above-mentioned connecting devices 5, 5' rotatably connect the end of the rod 7 to a projection 6 protruding from the periphery of the top wall of the fork. Although the wheels 4 and 4' are rotated by sliding the wheels 4 and 4' after turning, other methods may be used to interlock the wheels 4 and 4'.
また、旋回後車輪４，４′の旋回角度を旋回前
車輪３，３′よりも大きくする方法としては、図
示の場合旋回後車輪４，４′のフオークの頂壁回
動支点を偏心させてある。 In addition, as a method of making the turning angle of the rear turning wheels 4, 4' larger than that of the front turning wheels 3, 3', in the case shown in the figure, the top wall rotation fulcrum of the fork of the turning wheels 4, 4' is made eccentric. be.
この考案に係る運搬車は、以上の構成であつ
て、走行時に運搬車Ａを方向転換すると、旋回前
車輪３，３′が転換方向に旋回する。 The transport vehicle according to this invention has the above-described configuration, and when the transport vehicle A changes direction while traveling, the front turning wheels 3 and 3' turn in the direction of change.
このとき、ロツド７を介し旋回後車輪４，４′
を前記旋回前車輪３，３′の反対方向に旋回させ
るので、運搬車Ａの方向転換がスムーズになる。 At this time, the wheels 4, 4' after turning are connected via the rod 7.
Since the front wheels 3 and 3' are turned in the opposite direction, the direction of the transport vehicle A can be changed smoothly.
以上のように、この考案に係る運搬車によれ

As described above, according to the carrier according to this invention, when the front wheel turns in the direction of change due to a change in direction, the rear wheel is forced to turn in the opposite direction of the front wheel through the coupling device. When changing direction, you can easily change direction by turning the wheels in the opposite direction after turning without having to stop the transport vehicle, pull the handle with one hand, and push the handle with the other hand. Since you can apply pushing force with both hands, you can change direction while driving.
また、旋回後車輪の旋回角度は、旋回前車輪よ
りも大きくなるようにしてあるので、方向転換の
切れがよく、スムーズな方向転換が可能になる。 Further, since the turning angle of the after-turning wheels is larger than that of the pre-turning wheels, the direction change can be made sharply and smoothly.
