【考案の詳細な説明】
本考案は、ダンプカー荷台を上げたまま発車す
る危険を確実に防止する装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a device that reliably prevents the danger of starting a dump truck with its loading platform raised.
ダンプカーは運転者１人の操作によつてその荷
台の一方を上げ、積載した荷物を滑落させるので
荷おろしに人手を要せず、砂利、砂、廃棄物の運
搬などに広く使用されている。 Dump trucks are operated by a single driver to raise one side of the loading platform and allow the loaded cargo to slide down, so no manpower is required to unload the cargo, and the dump truck is widely used for transporting gravel, sand, waste, etc.
しかし、積載物を落下させた後、運転者の不注
意により荷台を上げたまま走行する危険があり、
このため、高所に張られたケーブルやガード等に
上つた荷台をぶつけたりする事故が発生してい
る。 However, there is a danger that the driver may drive with the cargo platform raised due to carelessness after dropping the cargo.
As a result, accidents have occurred in which cargo platforms that have climbed onto cables, guards, etc. stretched at high places collide with each other.
通常ダンプカー運転席には荷台が上つているこ

あるので、運転者に発車前に荷台の状態を強制的
に知られ、事故の発生を絶対確実に防止する装置
の出現は、ダンプカーを使用する業者の切望する
ものであつた。 Normally, there is a signal in the driver's seat of a dump truck to indicate that the loading platform is up, but since the signal is a lamp display, there is a risk of forgetting it.
The penalty in the event of an accident is huge, so the advent of a device that will force the driver to know the condition of the loading platform before starting the vehicle and absolutely prevent accidents from occurring will make it easier to use dump trucks. It was something that businessmen desperately wanted.
本考案は上記の事情を考慮してなされたもの
で、その目的はダンプカーの荷台を上げたまま走

に支持されている。 The rectangular box body 6a is provided at the front end of the beam 2, and has a structure without a bottom plate and one side plate. The front end of the shaft 3 passes through one surface of the box 6a, and a fan rib 6d is attached at a right angle to the axis of the shaft 3 at the tip 6c of the shaft 3 inside the box 6a.
is fixed. Inner upper surface 6b of the box body 6a
Each side of a fan cloth 6e is attached between the fan rib 6d and the fan rib 6d. This fan cloth 6e is a box body 6
Fan rib 6d at the tip 6c of the shaft 3 in a
It is supported so as to open in a fan shape by a large number of fan ribs 6f rotatably fitted to the inside of the fixed portion of the shaft 3.

より運転者の視界は開放され、運転可能となる。 When the loading platform of the dump truck is lowered, it comes into contact with the adjustment rod 5g inserted and fixed to the upper part of the drive rod 5c, and the drive rod 5
c is pushed down to the position indicated by the two-dot chain line in FIG. 3 against the coil spring 5b. At this time, the mutual positions of the upper and lower supports 5e and 5f do not change and they shift to the lower part, so the wire 5d, which is locked between them and is provided around the wheel 3a, rotates the wheel 3a in the direction of the arrow. Along with this, the shaft 3 also rotates, and the fan rib 6d fixed to the front end 6c rotates in the direction of the arrow in FIG. Trapped. This opens the driver's field of vision and allows him to drive.

ある。 Furthermore, when the loading platform is raised to drop the loaded object, the drive rod 5c returns to the position shown by the solid line in FIG.
rotates in the direction opposite to the arrow shown in FIG. At this time, the fan cloth 6e
One end is attached to the fan rib 6d, and the other end is attached to the fan rib 6d, so when the fan rib 6d rotates, the fan cloth 6e spreads out in front of the driver's field of vision, blocking the driver's field of vision. This makes it impossible to drive with the cargo platform raised. In addition, the adjustment rod 5g
By adjusting this, the lowering of the drive rod 5c can be adjusted, so the rotation of the fan rib 6a that rotates via the wheel 3a and the shaft 3 can be adjusted, and therefore the opening of the fan cloth can be adjusted. It can be adjusted freely.
以上述べたように本考案に係るダンプカー用走
行警報装置は荷台が上つている時は運転者の視界

を絶対確実に防止することが出来るものである。 As mentioned above, the travel warning device for a dump truck according to the present invention blocks the driver's view when the loading platform is up, and is housed in a closed box above the visibility when the loading platform is lowered. Unless the dump truck's loading platform is lowered, it will be impossible to drive the dump truck.
It is possible to absolutely prevent accidents caused by driving with the cargo platform raised.
また、遮へい部材は箱体にコンパクトに収納さ
