実開昭53−40910号公報や実公昭39−14101号公報
等に記載された構成が知られている。Prior Art The support structure of the rear cargo frame of a dump truck is as follows:
The configurations described in Japanese Utility Model Publication No. 53-40910 and Japanese Utility Model Publication No. 39-14101 are known.

これらの構成では、後側荷枠の上端を左右の側
枠へ枢支して下方が外方へ開放する状態と、下端
を荷台側へ枢支して上方が外方へ開放する状態と
に切り換え可能にしている。 In these configurations, the upper end of the rear cargo frame is pivoted to the left and right side frames and the lower part is opened outward, and the lower end is pivoted to the cargo platform side and the upper part is opened outward. It is switchable.

荷を降ろす場合に、荷枠の下方が外方へ開放回動
するように荷枠の左右両上端部を左右の側枠に枢
支しているので、左右の側枠を倒せば荷枠も倒れ
る。Problems to be solved by the invention: The rear cargo frame of a dump truck has both left and right upper ends of the cargo frame so that when the cargo platform is dumped to unload a load, the lower part of the cargo frame can be rotated outward. Since it is pivoted to the left and right side frames, if you tilt the left and right side frames, the cargo frame will also collapse.

しかしながら、木材等の長尺物を荷台上へ横方
向に置いて運搬する場合には、左右側枠を倒し後
側荷枠を起立状態のままで保持出来れば便利であ
る。 However, when transporting a long object such as wood by placing it laterally on a loading platform, it would be convenient if the left and right side frames could be collapsed and the rear loading frame could be held in an upright position.

そこで、本考案では、左右の側枠を倒しても後
側荷枠のみで起立状態に保持しようとするもので
ある。 Therefore, in the present invention, even if the left and right side frames are folded down, only the rear cargo frame is used to maintain the upright position.

構成した。Means for Solving the Problems In the present invention, in a dump truck in which the loading platform 3 is directed rearward relative to the vehicle body equipped with a traveling device, a longitudinal direction is provided at the left and right ends of the rear loading frame 1. The support hole 2 of the loading platform 3 is provided, and the support hole 2 of the loading platform 3 is provided.
A vertical locking hole 4 is provided at a position facing the rear cargo frame 1, and a support column 6 having a pivot portion 5 at the top thereof is fixed by passing through the support hole 2 and the locking hole 4. In the upright state, the support column 6 is fitted and fixed only into the support hole 2, and the upper pivot 5 is connected and pivoted to the left and right upright side frames 7, 7, so that the lower part of the rear cargo frame 1 is directed outward. It is configured so that it can be changed to a rotatably held state as appropriate.

方へ回動して開放状態となるのである。 In addition, when loading and transporting earth and sand on the loading platform 3, the left and right side frames 7, 7 and the rear loading frame 1 are erected, and when the loading platform 3 is dumped, the lower part of the rear loading frame 1 is exposed. In this case, the support column 6 is fitted and fixed only into the support hole 2 of the rear cargo frame 1, and the upper pivot point 5 is fixed. By being pivoted to the left and right side frames 7, 7, the lower part of the rear cargo frame 1 rotates outward when the cargo platform 3 is dumped, and becomes open.

このように、後側荷枠１の支持状態を支柱６の
取り付け位置変更によつて容易に行えることにな
る。 In this way, the supporting state of the rear cargo frame 1 can be easily changed by changing the mounting position of the support columns 6.

Further, a female threaded portion 15 is provided at the upper and lower intermediate portions of the square timber, and a thumb screw 16 screwed into this female threaded portion 15 is used to fix the support column 6 fitted into the support hole 2. Further, on the lower side of the cargo frame 1, a hanging rod 17 is provided to protrude downward, so that a hook 18 provided on the lower side of the cargo platform 3 can be engaged with or removed from the hook 18. This hook 18 is engaged with the locking rod 17 when the loading platform 3 is not being dumped, and is disengaged when the loading platform 3 is being dumped.

支柱６の上部には、前記側枠７の上部に設けた
ピン係止用凹部９に嵌合するピン１９を突設した
支腕２０を固着して、枢支部５を構成している。 A support arm 20 having a protruding pin 19 that fits into a pin locking recess 9 provided in the upper part of the side frame 7 is fixed to the upper part of the support column 6, thereby forming the pivot support 5.
