Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side guard for a freight vehicle, which can be used as a side step when unloading and unloading a side guard for a freight vehicle.

[0002]

2. Description of the Related Art In a freight vehicle equipped with a van type rear body, in addition to a type having a left and right opening (double door opening) door at the rear end of the loading platform, sliding doors are provided on the left and right sides of the loading platform. The type provided is known.

This type of freight vehicle equipped with doors on the left and right sides of the loading platform is easier to access the inside of the loading platform when loading and unloading cargo, compared to the type with a door only on the rear end of the loading platform. And is used, for example, for transporting bottled soft drinks.

[0004]

However, in a freight vehicle of the type in which doors are provided on the left and right sides of the luggage carrier, the side guards obstruct the step of assisting the climbing of the luggage carrier between the front and rear wheel axles of the vehicle body. It is difficult to directly equip the side frame of the vehicle, so that there is a disadvantage in that when the step is prepared separately, and the prepared step is placed on the road surface before unloading and unloading, the work must be started.

In order to eliminate such inconvenience, it is conceivable to equip a side guard with a step, for example, but a new problem arises that the step projects from the left and right side portions of the vehicle body. In addition, it is conceivable to equip the side guard with the step so that it can be folded, but a new problem arises such as a complicated structure.

[0006] Therefore, an object of the present invention is to provide a side guard for a freight vehicle, in which the side guard can be used also as a step to unload and improve the efficiency of the unloading work.

[0007]

To achieve the above object, according to the present invention, a side guard of a side frame of a vehicle body is erected substantially vertically via a hinge portion and a position laid substantially horizontally. The feature is that it is equipped so that it can swing between.

[0008]

According to the present invention, it can function as a side guard when the vehicle is running, and can function as a step when the side guard is horizontally laid down via the hinge portion when unloading and unloading.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings.

1 to 3 show an embodiment of the present invention. FIG. 1 shows an embodiment of a side guard for a freight vehicle of the present invention, as seen from one end side, and FIG.
FIG. 3 is an air circuit diagram of an actuator for driving the side guard of FIG. 3, and FIG. 3 is a side view of a truck equipped with the side guard of the present invention.

As shown in FIG. 1, the side guard 1 of this embodiment has a side guard bracket 4 and a side guard at a position between front and rear wheel axles of a side frame 3 having a substantially U-shaped cross section for supporting a van type rear body 2. It is swingably mounted via a hinge (hinge portion) 5 between a substantially vertical standing position and a substantially horizontal tilted position.

That is, the upper end portions at both longitudinal ends of the side guard 1 are respectively attached to the side guard brackets 4 when the side guard 1 is vertically erected (when the side guard 1 performs its original function). The side guard stopper 6 fixed to the end is brought into contact with the side guard stopper 6. The lower ends of the side guards 1 at both longitudinal ends are pivotally attached to the lower ends of hinge brackets 7 fixed to the side guard brackets 4 via side guard hinges (hinge parts) 5, respectively. When using as a step, it is designed to fall almost horizontally outside.

An air control cylinder 8 as an actuator is connected to the side guard 1. The control cylinder 8 swings the side guard 1 between a substantially vertical standing position and a substantially horizontal falling position. The tip of the rod portion 8a of the control cylinder 8 is pivotally attached to the intermediate height position of the side guard 1 via the clevis joint 9a, and the rear end of the cylinder portion 8b is attached to the lower surface of the side frame 3 via the clevis joint 9b. It is pivotally attached.

Cylinder portion 8b of control cylinder 8
The compressed air is fed from the air compressor 10 through the air tank 11, the solenoid valve 12, and the air pipe 13. The solenoid valve 12 is controlled by a switch 16 connected to a power source (battery) 15.

The side surface of the van type rear body 2 is shown in FIG.
As shown in, the slide type door 2a is equipped.

According to the side guard 1 of the above embodiment, the rod 8a is retracted into the cylinder 8b when the vehicle is running, and the rod 8a is erected substantially vertically with the upper end of the side guard 1 abutting the side guard stopper 6. It is maintained in its position and performs its original function (prevention of accidents involving left turn, protection of fuel tank, etc.).

When the slide type door 2a on the side of the van type rear body 2 is opened to unload a cargo (for example, bottled soft drink or its empty bottle) and unload it, the switch 16 is operated. When pressurized air is fed to the cylinder portion 8b through the solenoid valve 12 and the rod 8a is moved forward, the side guard 1 falls through the side guard hinge 5 until it becomes substantially horizontal with respect to the road surface, and in that state. Maintained. As a result, the side guard 1 is a step that assists when the side guard 1 is raised to the van-shaped rear body 2. Therefore, the worker can easily carry out the unloading work of the cargo by using the horizontally fallen side guard 1. When the cargo is unloaded and unloaded, the switch 16
Is operated to retract the rod 8a into the cylinder 8b to return the side guard 1 to the standing position.

As described above, according to this embodiment, since the side guard 1 can be used as a step, it is not necessary to prepare the step separately, and the side guard 1 can be tilted horizontally by operating the switch 16. You can stand it up without any hassle. Further, since the side guard 1 also serves as a step, the configuration is simple as compared with the case where the side guard is equipped with a separate step.

The side guard of the freight vehicle of the present invention is not limited to that shown in the above embodiment. For example, the rod 8a of the control cylinder 8 may be pivotally attached to the upper end of the side guard 1. Alternatively, the control valve 8 may not be provided, and the side guard 1 may be manually tilted or raised. In this case, the upper end portion of the side guard 1 uses the engaging means such as a hook or the like to form the side frame 3 or the side guard bracket 4.
It is engaged and disengaged with. Further, the side guard hinge 5 is provided with a stopper function so that the side guard 1 will not be further rotated and drooped when the side guard 1 is tilted until it becomes horizontal.

[0020]

As described above, according to the present invention, the side frame is provided with the side guard so as to be swingable between the position where the side guard is erected substantially vertically through the hinge portion and the position where the side guard is substantially horizontal. Therefore, the side guard can also be used as a step, and it is possible to improve the efficiency of unloading and unloading work. Further, compared to the case where the step is prepared separately or the step is equipped on the side guard, it is possible to make the configuration simpler without trouble.
