(57) [Abstract] [Purpose] By providing one fixed wheel at the center of the back surface of a turning four-wheeled hand truck, it is possible to provide a convenient hand truck that has stable straightness and can make small turns. [Structure] It is characterized in that a fixed wheel (2) is provided at the center of the back surface of the loading platform (1), and turning wheels (3) are provided at the four corners of the back surface of the loading platform (1).
Description
【０００１】[0001]
この考案は、直進性が良く、且つ小回りも出来るようにしたハンドトラックに関 するものである。 The present invention relates to a hand truck that has good straightness and is capable of making small turns.
【０００２】[0002]
従来、荷台の裏面四隅に旋回車輪を設けたハンドトラックがあった。 Conventionally, there has been a hand truck in which turning wheels are provided on the four corners of the back surface of the loading platform.
【０００３】[0003]
これは次のような欠点があった。 （イ）操作方法が悪かったり、通路の形状によっては、思わぬ方向え移動し、運 搬車を操作するのが難しく、直進性が悪かった。 （ロ）方向を換える場合、支点が無い為に操作するのが難しかった。 本考案は、これらの欠点を除くためになされたものである。 This had the following drawbacks. (B) Depending on the operation method or the shape of the aisle, it could move in an unexpected direction, making it difficult to operate the transport vehicle, and the straightness was poor. (B) When changing the direction, it was difficult to operate because there was no fulcrum. The present invention has been made to eliminate these drawbacks.

ハンドトラックの荷台（１）の裏面中央に固定車輪（２）を設け、支台（５）リ ンク（６）引っ張りスプリング（７）を介して設け、荷台（１）の裏面四隅に旋 回車輪（３）を設ける。 本考案は、以上のような構成よりなるハンドトラックである。 A fixed wheel (2) is provided in the center of the back surface of the loading platform (1) of the hand truck, and it is provided via the abutment (5) link (6) tension spring (7), and turning wheels are provided on the four corners of the back side of the loading platform (1). (3) is provided. The present invention is a hand truck having the above configuration.
【０００５】[0005]
ハンドトラックを押すと、ハンドトラックは床の形状に影響されず、通常、固定 車輪（２）の向いている方向に直進する。 ハンドトラックを右又は左に操作すると、ハンドトラックは固定車輪（２）の床 面との接点を支点として任意の方向に変換することが出来る。 When pushing the hand truck, the hand truck is not influenced by the shape of the floor and normally goes straight in the direction of the fixed wheels (2). When the hand truck is operated to the right or left, the hand truck can be converted in any direction with the contact point of the fixed wheel (2) with the floor as a fulcrum.
【０００６】[0006]
【実施例】 以下、本案の実施例について説明する。 （イ）ハンドトラックの荷台（１）の下面中央に、直進方向を維持するための固 定車輪（２）を支台（５）リンク（６）引っ張りスプリング（７）を介して設け 、固定車輪（２）が上下に移動出来る構造とし、凹凸のある床面でも常時床面と 固定車輪（２）が接触し、床面と固定車輪（２）との摩擦力を維持出来るように する。 （ロ）ハンドトラックの荷台（１）の下面四隅に、軸が旋回する車輪（３）を設 ける。例えばキャスターの小さな車輪。 （ハ）固定車輪（２）は、四隅に設けた旋回車輪（３）より小径の車輪とする。 なお第４図、又は第５図に示すように、引っ張りスプリング（７）の代わりに、 板スプリング（８）又は弾力性スポンジ（９）を荷台（１）の下面と固定車輪（ ２）との間に装着してもよい。 本案は、以上のような構造である。 本案は、旅行カバン、寝台、陳列台、移動式機械、買い物用運搬車、配膳台、 製品ラック、各種台車等にも応用することが出来る。EXAMPLES Examples of the present invention will be described below. (A) A fixed wheel (2) for maintaining a straight traveling direction is provided in the center of the lower surface of the loading platform (1) of the hand truck via the abutment (5) link (6) and tension spring (7), and a fixed wheel. (2) can move up and down so that the floor surface and the fixed wheel (2) are always in contact with each other even on the uneven floor surface, and the friction force between the floor surface and the fixed wheel (2) can be maintained. (B) Wheels (3) on which the shaft turns are installed at the four corners of the lower surface of the bed (1) of the hand truck. For example, the small wheels of a caster. (C) The fixed wheel (2) has a smaller diameter than the turning wheel (3) provided at the four corners. As shown in FIG. 4 or FIG. 5, a leaf spring (8) or an elastic sponge (9) is used instead of the tension spring (7) to connect the lower surface of the bed (1) and the fixed wheel (2). May be installed between. The present proposal has the above structure. The plan can also be applied to travel bags, berths, display stands, mobile machines, shopping carts, food carts, product racks, and various carts.
