Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mud guard effective for application to a truck or the like.
[0002]
[Prior art]
5 and 6 schematically illustrate a general truck cab, in which 1 is a cab, 2 is a door, 3 is a front wheel, and 4 is a step for assisting getting in and out of the cab 1. Each step 4 is arranged at the lower front end of the cab 1 and is supported from the side rail 5 via a support arm (not shown).
[0003]
When such a truck travels on a rough road, the muddy water splashes obliquely forward at the moment when the front wheel 3 enters the puddle, and the grounding point of the front wheel 3 sinks in the puddle of the puddle 1 so that the cab 1 Since the whole sinks slightly, there is a possibility that the step 4 or the door 2 arranged just before the front wheel 3 may be contaminated by the splashing of muddy water, and the rear surface facing the front wheel 3 of the step 4 to prevent this. A mudguard 6 is attached to the base to make it hang down.
[0004]
That is, in step 4 of this type of truck, mud etc. on the back of the shoe is formed in the shape of a cocoon so as not to slip and accumulate in step 4, so if the mudguard 6 is not equipped, the front wheel 3 The splashed muddy water passes through the step 4 from below and reaches the upper surface of the step 4, the door 2, and the like.
[0005]
[Problems to be solved by the invention]
However, since the conventional mudguard 6 as described above only hangs down between the step 4 and the front wheel 3, there are various factors such as vehicle speed, muddy water jumping angle, and wind pressure influence. There are many cases in which mud water reaches the upper surface of step 4 or the door 2 due to the action, and mud water reaches the upper surface of step 4 or the door 2, etc. Yes.
[0006]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a novel mudguard capable of preventing the jumping of muddy water more reliably than before.
[0007]
[Means for Solving the Problems]
The present invention is a mud guard that is mounted on a vehicle having a step for getting on and off at the lower front end of a cab and prevents muddy water from splashing up to the step by a front wheel, and covers the lower surface of the step with a required gap. The front and rear end portions of the step are attached to the front and rear surfaces of the step so as to be able to do so, and the portion covering the lower surface of the step has a downward slope toward the inner side in the vehicle width direction. A curved slope is formed .
[0008]
Thus, since the entire area of the lower surface of the step is covered with the mudguard in this way, no matter what pattern the muddy water is splashed by the front wheel, the mudguard can approach the lower surface of the step. This prevents the muddy water splashed by the front wheels from passing through the step from below and reaching the upper surface of the step, the door, or the like.
[0009]
In addition, since the lower surface of the step is covered with a required gap, mud etc. on the back of the shoe can be dropped under the step without any trouble as in the conventional case through the step ridge structure. Slip of shoes when getting on and off due to accumulation of mud etc. on the upper surface of the door is prevented beforehand.
[0010]
Furthermore, when viewed from the side of the vehicle, which is the direction of getting into the cab, the mudguard is almost hidden under the step, and the presence of the mudguard becomes inconspicuous.
[0011]
In the present invention, since the curved slope such that for descending slope inward in the vehicle width direction is formed in a portion covering the lower surface of the step, on the mudguard and dropped mud through louver structure of step It is possible to slide down with the slope of the curved slope without accumulating on the surface.
[0012]
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0014]
1 to 4 show an example of an embodiment for carrying out the present invention, and portions denoted by the same reference numerals as those in FIGS. 5 and 6 represent the same items.
[0015]
As shown in FIG. 1, the mud guard 7 in this embodiment is arranged in the vehicle front-rear direction (left and right in FIG. 1) so as to cover the lower surface of the step 4 provided at the lower front end of the cab 1 with a required gap. The front and rear end portions thereof are attached to the front and rear surfaces of the step 4 respectively.
[0016]
That is, as shown in FIG. 2, the step 4 where the mudguard 7 is to be mounted is supported via a U-shaped bracket 9 by a support arm 8 extending from the side rail 5 side in the vehicle side surface direction. Therefore, the front and rear end portions of the mudguard 7 are mounted on the front and rear surfaces of the step 4 together with the bracket 9.
[0017]
Here, as shown in FIG. 3, the mounting holes F ₁ , F ₂ and R ₁ , R ₂ opened in the front end portion and the rear end portion of the mud guard 7 are arranged in the width direction of the mud guard 7 (the horizontal direction in FIG. 3). ) Have offset amounts S ₁ and S ₂ in the front-rear direction (vertical direction in FIG. 3), and these mounting holes F ₁ , F ₂ and R ₁ , R ₂ are connected to step 4 and bracket 9. A curved slope 7a that forms a downward slope toward the inner side in the vehicle width direction as shown in FIG. It is formed in the part which coat | covers.
[0018]
The mud guard 7 can be mounted so that a curved slope 7a having a downward slope inward in the vehicle width direction is formed in the right and left steps 4 by using the mud guard 7 upside down. The number of parts of the mudguard 7 is only one.
[0019]
Further, in this embodiment, the mounting position of the rear end portion of the mud guard 7 with respect to the rear surface of the step 4 is raised to the uppermost position of the rear surface of the step 4, and the entire rear surface of the step 4 is covered with the mud guard 7. It has become so.
[0020]
Thus, since the entire lower surface of the step 4 is covered with the mud guard 7 in this way, mud water is splashed up by the front wheel 3 in any pattern, so that all of the mud guard 7 The approach to the lower surface is prevented, and it is avoided that the muddy water that the front wheel 3 jumps up passes through the step 4 from below and reaches the upper surface of the step 4, the door 2, and the like.
[0021]
Therefore, according to the above-described embodiment, it is possible to prevent the muddy water from jumping more reliably than before, and to prevent the upper surface of the step 4 and the door 2 from being contaminated by the muddy water that the front wheel 3 has bounced up. Can do.
[0022]
In addition, since the lower surface of Step 4 is covered with a required gap, mud etc. on the back of the shoe can be dropped below Step 4 without any trouble as in the past through the hook structure of Step 4. As a result, it is possible to prevent slipping of the shoes when getting on and off due to accumulation of mud or the like on the upper surface of Step 4, and thus it is possible to ensure good safety as in the conventional case.
[0023]
Further, as shown in FIG. 1, the mud guard 7 is almost hidden under the step 4 when viewed from the side of the vehicle, which is the direction of getting into the cab 1, and the presence of the mud guard 7 becomes inconspicuous. The appearance can be greatly improved as compared with the conventional one.
[0024]
Further, in particular, in the present embodiment, a curved slope 7a is formed in the portion covering the lower surface of step 4 so as to have a downward slope toward the inner side in the vehicle width direction. The mud etc. can be slid down with the slope of the curved slope 7 a without accumulating on the mudguard 7.
[0025]
Further, since the mounting position of the rear end portion with respect to the rear surface of Step 4 is raised to the uppermost position of the rear surface of Step 4 so as to cover the entire area of the rear surface, pebbles and the like jumped up by the front wheel 3 are easy to hit directly. The rear face of step 4 can be protected.
[0026]
It should be noted that the mud guard of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
