Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a step for getting on and off a vehicle for getting on and off a cargo box of a truck.

[Conventional technology]

Conventionally, as shown in Japanese Utility Model Application Publication No. 50-156934, for example, a step is foldably supported on the inner wall of a sliding door of a cargo box, and when the sliding door is opened and hung down, the step protrudes from the inner surface of the sliding door. It is suggested that something be done. This is convenient when a large number of workers get into the cargo box, but if there is a small number of workers, the sliding door must be pulled down each time they get on and off, and the sliding door cannot be closed after everyone has boarded the cargo box. This is an inconvenience. Further, if a trailer is connected to the rear of the vehicle, the sliding door cannot be pulled down, so it is useless.

[Problem that the invention attempts to solve]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a step for getting on and off a vehicle, which makes it easy to get into and out of a cargo box, regardless of whether the sliding door is open or closed.

[Means to solve the problem]

In order to achieve the above object, the structure of the present invention is such that one end of a ladder, which is longer than the height of the sliding door, is pivotably supported on the lower edge of the outer surface of the sliding door of the cargo box so that it can be turned upside down.

[Effect]

The ladder is longer than the height of the sliding door, and one end of the ladder is pivotably supported on the lower edge of the outer surface of the sliding door so that it can be turned upside down, so the other end of the ladder protrudes above the sliding door. Therefore, when the sliding door is pulled down, the ladder protrudes below the sliding door, making it easier to get on and off the cargo box.

It is also possible to pull down only the ladder and step over the sliding door to get into the cargo box.

[Example of idea]

As shown in FIG. 1, a vehicle frame 3 supporting wheels 2
A cargo box surrounded by a bottom plate 19, side plates 13 and sliding door 12 is supported on the top. The sliding door 12 is supported by a hinge 9 at the rear end edge of the bottom plate 19 so as to be openable and closable.

According to the present invention, on the lower edge of the outer surface of the sliding door 12,
The ladder 10 is rotatably supported by the support shaft 14 . Preferably, the footboard 7 is supported on the inner surface of the sliding door 12 by a support shaft 8. The tread 7 is placed in a rectangular recess 20 (second
(Figure). A stopper 4 made of an elastic material is attached to the rear end of the vehicle frame 3, and when the sliding door 12 is lowered, the ladder 10 hits and is held so that the ladder does not swing.

As shown in FIG. 2, the ladder 10 is made of, for example, a steel bar bent into a U-shape, and both ends are supported by a support shaft 14 at the lower edge of the outer surface of the sliding door 12, and a step bar 16 is connected to the middle. A cylindrical boss 17 is connected to the outer surface of the sliding door 12 by welding or the like.
A locking pin 18 is supported which is biased upwardly by a spring. When the ladder 10 is inverted, a lock pin 18 can be inserted into a hole provided in one of the step bars 16.

Next, the operation of the ingress/egress step according to the present invention will be explained. Normally, the ladder 10 is pressed against the outside of the sliding door 12 in an inverted position and fixed by a locking pin 18, as shown by the solid line in the left half of FIG.

When a small number of workers get into the cargo box, they pull down the lock pin 18 and tilt the ladder 10 about the support shaft 14, so that it hits the stopper 4 of the vehicle frame 3, as shown by the solid line in FIG. Therefore, the worker can step over the sliding door 12 and get into the cargo box by putting his foot on the step rod 16. Ladder 1 when getting on and off workers
The vibration at 0 is suppressed by the stopper 4.

When a large number of workers get on board, the sliding door 12 is pulled down while the ladder 10 is fixed to the sliding door 12 by the lock pin 18, as shown in the right half of FIG. At this time, the ladder 10 hits the stopper 4.
The footboard 7 housed inside the sliding door 12 is pulled out. The worker can quickly get on the ladder 10 by putting his feet on the step bar 16 and the step board 7. After the last two people close the sliding door 12, the driver uses the ladder 10 to step over the sliding door and get into the vehicle, and the ladder 10 can be easily retracted by the driver.

Previously, when getting off the vehicle, either the driver or an assistant would get off first and pull down the sliding door, or one worker would jump out of the cargo box and pull down the sliding door, but in the latter case, slipping and other problems could occur. There was a danger of

According to the present invention, when a small number of people are disembarking the vehicle, the workers can safely disembark the vehicle by lowering the ladder onto the loading platform. In this case, even if the trailer is connected, the ladder can be used to safely get on and off the vehicle. Also, if a large number of people are getting off the train, the person who gets off first can pull down the sliding door.

Since the ladder 10 is inverted in the retracted state and fixed to the sliding door 12, and protrudes above the sliding door 12, it also serves as a fence to prevent the worker from falling backwards due to the shaking of the vehicle body. .

[Effect of idea]

As described above, in this invention, one end of a ladder that is longer than the height of the sliding door is supported by a shaft on the lower edge of the outer surface of the sliding door of a loading box so that it can be turned upside down. Regardless of whether the sliding door is open or closed, you can use the ladder to straddle the sliding door and get on and off the cargo box, regardless of whether the sliding door is open or closed. The ladder was pulled down with it,
Since the ladder protrudes below the sliding door, it is possible to get on and off the cargo box using the ladder.

The ladder is supported by a sliding door and does not swing, so it is safe to get on and off the ladder.

The length of the ladder is longer than the height of the sliding door, and when the sliding door is pulled down, the ladder protrudes below the sliding door, so using the ladder makes it easier to get on and off the cargo box.

[Brief explanation of the drawing]

Figure 1 is a side view showing the rear of a vehicle equipped with a step for getting on and off the vehicle according to the present invention, and Figure 2 shows the left half with the sliding door closed and the right half with the sliding door open. FIG. 6 is a rear view of each. 10: Ladder, 12: Sliding door, 14: Support shaft, 1

Claims (1)

[Scope of utility model registration request] This step for getting on and off a vehicle is characterized in that one end of a ladder, which is longer than the height of the sliding door, is pivotably supported on the lower edge of the outer surface of the sliding door of a cargo box so that it can be turned upside down.
