Abstract

PROBLEM TO BE SOLVED: To secure a scaffold which is used in cleaning of a windshield and the like by arranging a step, which opens/closes a running wind inlet formed on the bumper face and can be developed substantially horizontally toward the bumper front side, and forming a louver, which guides the running window to a radiator, on the step. SOLUTION: A running wind inlet 4 is arranged in the central part of a bumper face, and a straightening recess 5 gathering the running wind toward the inlet 4 is formed. A step 6 opening/closing the inlet 4 is arranged, while a louver 7 guiding the running wind to a radiator is formed in the step 6. When the step 6 is developed in front of the bumper face for use, it is hooked on the lower edge of the inlet 4, so that a substantially horizontal scaffold is formed. Therefore, cleaning work of a windshield and the like can be carried out efficiently by stepping on the step 6. In an unused time, the step 6 is turned upward so as to be stored in the position, in which the step 6 covers the running wind inlet 4 opened on the bumper face, so as to function as a louver 7 guiding the running wind to the radiator.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a front bumper for a vehicle.

[0002]

2. Description of the Related Art In a large vehicle such as a truck, when cleaning a front window from the outside of a driver's cab (cab), a front bumper at a lower portion of the front of the cab is often used as a step. Unstable and difficult to work. Therefore, as a conventional example, a radiator grill on the front of the cab can be used as a step, and a step on the upper surface of the front bumper to expand the scaffolding can be stored (see FIG. 6).
No. 1-152541, Japanese Utility Model Laid-Open No. 57-62148, Japanese Utility Model Laid-open No. 60-106858).

[0003]

However, in order to be able to use the radiator grill as a step, it is necessary to increase the strength of the grill itself, resulting in a problem that the weight of the grill is greatly increased. It is difficult to secure a storage location for the steps that can be deployed on the upper surface of the front bumper, and in some cases, the area of the radiator grille for intake of the traveling wind may be reduced.

[0004] An object of the present invention is to solve such a problem.

[0005]

According to a first aspect of the present invention, in a front bumper disposed below a front surface of a cab, an intake of a traveling wind is formed on a surface of the bumper, and the intake is opened and closed to use the bumper. A step that can be deployed substantially horizontally ahead of the surface is provided, and a louver that guides traveling wind to the radiator is formed in this step.

In a second aspect, the step in the first aspect comprises a bendable stay that supports a load during use between the chassis frame and the chassis frame.

[0007]

According to the first aspect of the present invention, the steps form a substantially horizontal scaffold when deployed in front of the bumper surface during use.
When not in use, it is stored so as to close the intake of the traveling wind that opens on the bumper surface, and functions as a louver that guides the traveling wind to the radiator.

In the second aspect, the stay bends and expands with the opening and closing of the step, and when the stay extends in a straight line with the chassis frame, the stay properly supports the load of the step.

[0009]

FIG. 1 shows a front view of a cab-over type truck, in which a front bumper 1 is arranged at a lower front portion of a cab 2. Both ends of the front bumper 1 are bent rearward, and a rectifying portion 3 (opening the cut-and-raised surface of the dent) that guides the running wind to the cabside is formed at the corner.

At the center of the bumper surface, an intake 4 for the traveling wind is provided at a position symmetrical to the left and right, and a rectifying recess 5 for collecting the traveling wind at the intake 4 is formed. As shown in FIG. 2, a step 6 for opening and closing the intake 4 is provided, and a louver 7 for guiding the traveling wind to the radiator is formed in the step 6.

As shown in FIGS. 3 and 4, a bracket 9 is provided on the front end surface of the chassis frame 8, and the step 6 is attached to the bracket 9 via a pin 10 (horizontal axis), and is substantially horizontally forward of the bumper surface. Use position and mounting port 4
Between the storage position functioning as the louver 7.

In order to support the load of step 6, a stay 11 is interposed between the chassis frame 8 and step 6. In this case, the stay 11 is formed by two links a and b which can be freely bent and stretched, and the two links a and b extend in a straight line to suspend the step 6 in the use state where the step 6 is deployed substantially horizontally. .

With such a configuration, when the step 6 is deployed forward of the bumper surface during use, the step 6 hangs on the lower edge of the intake 4 and forms a substantially horizontal scaffold. At this time, the stay 11 extends in a straight line with the chassis frame 8, and appropriately supports the load of the step.

For this reason, the procedure goes to step 6, and the cleaning operation of the front window 20 (see FIG. 1) can be performed efficiently. When the stay 11 is not used, the stay 11 is turned upward while being bent, and the step 6 is stored in a position covering the intake 4 for the traveling wind opening on the bumper surface, and functions as a louver 7 for guiding the traveling wind to the radiator. I do.

In step 6, in order to set the use position higher, the position of the pin 10 (rotation fulcrum) with respect to the bracket of the chassis frame is provided at the upper part as shown in FIG. Then, you may comprise so that it may expand substantially horizontally. In this case, the stay 11 bends and stretches as the step is opened and closed,
It is desirable to add appropriate means for fixing the stretched state of the links a and b in order to reliably support the link from below.

[0016]

According to the first aspect of the present invention, in the front bumper disposed at the lower part of the front of the cab, the intake of the traveling wind is formed on the bumper surface, and the intake is opened and closed to use the front of the bumper when used. A step that can be deployed almost horizontally is provided, and a louver that guides the traveling wind to the radiator is formed at this step. By expanding the step, it is possible to easily secure a good scaffold used for cleaning the front window and the like. . Steps are stored when not in use, and function as louvers that guide the running wind to the radiator,
It is also possible to omit a dedicated louver.

According to the second aspect, the step in the first aspect includes a bendable and stretchable stay for supporting a load during use between the chassis frame and the chassis frame. Can be secured properly.
