貨物自動車の荷台への昇降装置に関し、その先行技術を公開公報（昭５５〜昭 ６４年）にもとづいて調査した。その結果、本考案と同じ目的の中・大型貨物車 に適した昇降装置は、実願昭５８−４５７４４及び実願昭６２−１５０３２９の ２件である。実願昭５８−４５７４４の装置は折りたたみ式ステップを荷台の床 下に収納する方式のため、後部ドアーが両開きのみ有効で、通常の貨物自動車に は装着不可能である。一方、実願昭６２−１５０３２９の装置は複数のリンクで リヤ・ゲートを昇降用ステップとして吊持する方式のため、構造が複雑で取付け やコスト面で難点がある。 Regarding the elevating device to the loading platform of a freight vehicle, the prior art was published in the public gazette (1983-1983). The survey was conducted based on the following: (1964). As a result, medium- and large-sized freight vehicles for the same purpose as this invention Lifting devices suitable for There are 2 cases. The device of Utility Application No. 58-45744 has a folding step installed on the floor of the loading platform. Because it is stored underneath, the rear door can only be opened on both sides, making it difficult to use on regular freight cars. cannot be installed. On the other hand, the device of Utility Application No. 150329/1986 has multiple links. Since the rear gate is suspended as a step for lifting, the structure is complicated and installation is difficult. There are also drawbacks in terms of cost.

本考案は、前記の通り構成した結果、例えば第１図に示すように、荷台へ上が ろうとする時には、まず、ステップ装置（４）を装着したゲート（１）を開き、 荷台下部へ降ろすと、ゲート（１）の内側に係止具（８）で横向きに吊設収納さ れたステップ装置（４）が目前に位置する。 次に、手で係止具（８）からステップ装置（４）を引き外し、自在継手具（３） を基点として手前に引きまわし、荷台後部斜めに立て掛けた後、ステップ（６） の前端を手前に引き下ろすと各ステップ（６）は連結索（７）の効果で引き出さ れると共に水平にセットされる。この時、ステップ装置（４）の支柱枠（５）と 連結索（７）の下端は路面上に、支柱枠（５）の上端は自在継手具（３）により ゲート（１）に支持されているのでステップ装置（４）の安定性は高い。また、 ステップ（６）支柱枠（５）と連結索（７）間に平行四辺形の状態で軸着されて いるため、各ステップ（６）はステップ装置（４）のセット角度や路面状況とは 関係なく常に水平にセットされる。 また、第２図のように、支柱枠（５）の下端に支柱保持盤（１０）を回動目在に 軸着すると、ステップ装置（４）の接地性が向上する。更に、図示の通り支柱枠 （５）と連結索（７）の側面に高さ調整用穴（９）を設けて、ステップ（６）を 固定しているボルト又はビスを脱着することにり各ステップ（６）の高さも変更 できる。荷台への昇降終了後は、前記手順とは逆にステップ装置（４）を持ち上 げ、自在継手具（３）を基点として横向きにした後、係止具（８）に支柱枠（５ ）を嵌入してゲート（１）の内側に吊設収納する。 As a result of the above-mentioned configuration, the present invention has a structure in which, for example, as shown in FIG. When attempting to do so, first open the gate (1) equipped with the step device (4), When lowered to the bottom of the loading platform, it is hung horizontally inside the gate (1) using the locking device (8). The stepped device (4) is located in front of the user. Next, remove the step device (4) from the locking device (8) by hand and remove the step device (4) from the universal joint device (3). Using this as a starting point, pull it toward you and lean it diagonally at the rear of the platform, then step (6) When you pull down the front end of the and set horizontally. At this time, the support frame (5) of the step device (4) The lower end of the connecting cable (7) is placed on the road surface, and the upper end of the support frame (5) is placed on the universal joint (3). Since it is supported by the gate (1), the stability of the step device (4) is high. Also, Step (6) The support frame (5) and the connecting rope (7) are pivoted in a parallelogram state. Therefore, each step (6) depends on the set angle of the step device (4) and the road surface condition. Regardless, it is always set horizontally. In addition, as shown in Fig. 2, a column holding plate (10) is placed at the lower end of the column frame (5) as a turning point. When the step device (4) is attached to the shaft, the grounding performance of the step device (4) is improved. Furthermore, as shown in the diagram, the support frame (5) and the connecting cable (7) with height adjustment holes (9) on the sides, and step (6). The height of each step (6) can also be changed by removing and removing the fixing bolts or screws. can. After completing the lift to the loading platform, lift the step device (4) in the opposite direction to the above procedure. After turning the universal joint (3) horizontally as a reference point, attach the support frame (5) to the locking tool (8). ) and hang it inside the gate (1).
