Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cabover type vehicle entry / exit device.

<Prior Art> As a conventional example of a boarding / alighting device for a cab-over type vehicle
There is one such as shown in Japanese Patent Publication No.-72840.

That is, a concave boarding step is formed below the door of the cab, and an openable door plate is provided so as to cover the boarding step.

Then, when the door is opened, the door plate is moved from the upper part of the boarding / alighting step to another position so that the driver can get on and off using the boarding / alighting step. Further, when the door is closed, the door plate covers the step for getting on and off so as to be substantially flush with the bumper to improve aerodynamic characteristics during traveling.

<Problems to be Solved by the Invention> However, in such a conventional boarding / alighting device,
Since a concave step for getting on and off is installed under the door of the cab, there is a problem that it is difficult to get on and off without gripping a handrail or the like, and it is not possible to get on and off with luggage. Also,
When a handrail or the like is gripped, the passenger comes in and out of the vehicle backward, so that the ingress / egress property is poor.

In addition, in Japanese Utility Model Application No. 62-42498, a step for getting on and off is provided that projects from the lower side of the door to the outside of the vehicle in a stepwise manner when the door is opened. Although a projecting handrail is disclosed, there is a problem in that the installation area of the device becomes large because the steps for getting on and off, the handrail, etc. are formed separately from the vehicle body.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a boarding / alighting apparatus that can easily get on and off without gripping a handrail or the like.

<Means for Solving the Problems> For this reason, the present invention is directed to a first flat plate mounted below the door of the cab and movable between the cab lower side and the cab outer side.
A step member, a second step member, which is provided in the vicinity of the first step member, has a step formed on one wall surface, and at least a part of a tire fender surface is formed on the other wall surface, and the second step member. A first actuator that moves the first step member between a lower side of the cab and an outer side of the cab; and a second actuator that rotates the second step member around a first end in a substantially vertical plane,
I was prepared.

<Operation> When the passenger gets on and off, the first and second step members are positioned outward of the cab to form stepped steps, while the first and second step members are positioned below the cab while traveling. Then, the second step member was used as a tire fender.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS.

1 and 2, a door 2 is provided on the side of the cab 1.
Is attached, and the cab 1 below the door 2 has a flat plate-shaped first
The step member 3 is attached so as to be freely movable in the vehicle width direction. Specifically, at the vehicle front end portion of the first step member 3, as shown in FIG. 3, the shaft 4 attached to the cab 1 is attached so as to be freely movable in the vehicle width direction. A first air cylinder 5 as a first actuator is attached to the vehicle rear end portion of the first step member 3, and a piston rod tip of the first air cylinder 5 is attached to the cab 1. The piston rod of the first air cylinder 5 is covered with a cover 6.

Further, one end of the support member 7 is attached to the front end portion of the vehicle of the first step member 3 so as to be swingable in a substantially vertical plane formed in the vehicle width direction, and the other end of the support member 7 is formed in the cab 1. It faces the long hole 8. A pin 9 is attached to the other end of the support member 7, and the other end of the support member 7 moves along the elongated hole 8.

When the first air cylinder 5 is operated, the first step member 3 is moved to the storage portion (not shown) below the cab 1 and the cab 1.
It is designed to move to and from the outside.

A second step member 10 is attached to the rear end portion of the vehicle of the first step member 3 via the main body of the first air cylinder 5 so as to freely swing in a substantially vertical plane. Are formed on stairs and the lower wall is formed on an arc. The second air cylinder 11 is provided on the lower wall of the second step member 10.
Is swingably mounted in a substantially vertical plane via a bracket 12, and the tip of the piston rod of the second air cylinder 11 is freely swingable in a substantially vertical plane below the first step member 3 via a bracket 13. Installed. The piston rod of the second hydraulic cylinder 11 is covered with rubber 14.

By operating the second air cylinder 11, the second step member 12 is rotated in a substantially vertical plane about the main body of the first air cylinder 5.

A storage portion 15 for storing the second step member 10 is formed below the cab 1 so as to face the tire 16.
The wall surface of 15 is formed in a stepped shape like the wall surface of the second step member 10. Then, the second step member 10 is
As shown in FIG. 4, when it is stored in the storage portion 15, it constitutes a part of the tire fender.

Here, when the first and second step members 3 and 10 are led out to the outside of the cab 1, first, the first air cylinder 5
After the first and second step members 3 and 10 are simultaneously drawn out to the outside of the cab 1 by the operation, the second air cylinder 11 is operated to rotate the second step member 10 in the clockwise direction in FIG. ing.

On the contrary, when the first and second step members 3 and 10 are to be housed, first, the second step member 10 is rotated counterclockwise in FIG. After being moved to the solid line position, the first and second step members 3 and 10 are moved below the cab 1 by operating the first air cylinder 5.

Further, the first and second air cylinders 5 and 11 interlock with the opening / closing operation of the door 1. For example, when the door 1 is opened by 30 °, the first and second air cylinders 5 and 11 start to operate.

Reference numeral 17 in FIG. 4 is a stopper for holding the second step member 10 in the storage portion 15.

Next, the operation will be described.

When the door 1 is opened, the first air cylinder 5 is operated to make the first
And the second step members 3 and 10 are moved from below the cab 1 to the outside of the cab 1. Immediately after the movement, the second step member 10 is moved by operating the second air cylinder 11.
The connection with the first step member 3 is rotated in the clockwise direction in FIG. 1 to move it to the position indicated by the chain line in FIG.

As a result, the first and second step members 3 and 10 allow the second
As shown in the figure, stepwise steps are formed. Therefore, the driver can easily get on and off the cab 1 without gripping the handrail or the like.

When the door 1 is closed, the second air cylinder 11 is operated to rotate the second step member 10 counterclockwise in FIG. 1 to move it to the solid line position in FIG. Immediately after the movement, the first air cylinder 5 is operated to move the first and second step members 3 and 10 below the cab. As a result, the first step member 3 is stored in the storage section below the door 2, and the second step member 10 is stored in the storage section 15 facing the tire 16. Therefore, during traveling, the second step member 10 can be used as a part of the tire fender. In this way, the second step member 10 is housed in the housing portion 15 so as to be a part of the tire fender, so that the boarding / alighting device can be installed in the vehicle without increasing the size.

<Effect of the Invention> As described above, the present invention moves the first and second step members to the outside of the door of the cab to form a step-like step while getting on and off, while the first step is provided when the vehicle is running. Since the second step member can be housed under the cab and the second step member can be used as a tire fender, the driver can easily get on and off without gripping a handrail or the like, and also the size of the getting on / off device can be increased. Can be suppressed.
