DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor mat for a construction machine laid on a floor board of a construction machine such as a snow plow or a wheel loader.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional construction machine floor mat 110 laid on a floor board of a cockpit of a construction machine such as a snow plow or a wheel loader. 121 is a control box provided in the cockpit, and 122 is a driver's seat. As described above, the construction machine floor mat 110 is laid around the driver's seat 122 on the floor board of the cockpit of the construction machine.

FIG. 7 is a diagram showing a cross section of the cockpit 150. In the cockpit 150 of the construction machine, a cabin unit 160 in which a roof 161 and a wall 162 are integrated is placed and fixed on a floor board 151 on which a control box 121 and a driver's seat 122 are provided. It is formed by. A part of the wall 162 of the cabin unit 160 is cut off as an entrance 163 to the cockpit 150. And in this doorway 163,
Usually, a door is provided. On the floor board 151 of the cockpit 150 thus formed, a floor mat 110 for construction machinery is laid.

FIG. 8 is an enlarged view of a portion A in FIG.

FIG. 9 shows a floor mat 1 for construction machinery.
FIG. 2 shows a schematic shape of No. 10 and a pattern of uneven portions for preventing slippage formed on the surface side of the floor mat 110 for construction machinery.

[0006]

Construction machines, unlike passenger cars, are usually used in work sites where there is a lot of dust. Therefore, the inside of the cockpit 150 is often covered with mud, and therefore, the construction machine floor mat 110 is easily worn or deteriorated, and it is necessary to replace it with a new construction machine floor mat.

However, floor mats 110 for construction machinery
Are not uniformly worn and degraded as a whole, but tend to have a partial bias in the degree of wear and deterioration. For example, the portion near the entrance 163 of the cockpit 150 (portion C in FIG. 9) is most frequently trampled, and hence is more worn and deteriorated than the portion on the opposite side (portion D in FIG. 9). However, even if a part of the floor mat is worn or deteriorated, the whole construction machine floor mat has to be replaced with a new one.

[0008] Various options are available for construction machines. For example, several control boxes having different shapes depending on the number of levers are prepared, and a control box selected from the control boxes is set in the cockpit 150 according to a user's request. If the control box has a different shape, it is necessary to lay a floor mat for a construction machine having a shape suitable for the control box. Referring to FIG. 9, a portion E in the figure is a portion cut out according to the shape of the control box. The part F in the figure is a part cut out for installing an air conditioner.
For example, if three types of control boxes having different shapes are provided as options, and three types of air conditioners having different shapes are provided as options, floor mats for construction equipment will have all of those options. It is necessary to prepare nine types of different shapes in consideration of the combination. There are various options other than the control box and air conditioner that are available as options, but in order to accommodate all combinations, it is necessary to prepare various types of floor mats for construction machinery with different shapes. is there.

In order to solve these problems, the floor mat for construction equipment may be divided into two types.
A gap or a gap is generated in the divided surface, and dust or earth and sand enters the gap, which makes cleaning difficult. In addition, the appearance when viewed from the front side is impaired.

On the other hand, as shown in FIG. 8, a step B is formed even when a floor mat 110 for construction equipment is laid below the entrance 163 of the cockpit 150 of the construction equipment. This means that the cabin unit 160 is placed on the floor board 151
This is due to the difference between the height of the step portion 164 for fixing and the thickness of the floor mat 110 for construction machinery. In recent years, the interior condition of the cockpit 150 of construction equipment has been improved, and it has approached that of passenger cars. However, if the inside of the cockpit 150 is dirty, the improved interior becomes meaningless, so it is necessary to make the inside of the cockpit 150 easy to clean. However, if there is such a step B, dust and earth and sand are likely to accumulate here, and especially if such a step B is provided below the entrance 163, it becomes difficult to sweep the dust from the entrance 163.

In order to eliminate the step B, the sectional shape of the floor mat for construction equipment may be as shown in FIG. Floor mat 21 for construction machinery as shown in FIG.
It is necessary to use a molding die 220 having a cross-sectional shape as shown in FIG. 10 (b) in order to form 0, but in order to form the die 220 having such a cross-sectional shape, it is necessary to cut out the acute angle portion G. is there. However, in actual die manufacturing, a small-diameter tool is used to cut out such an acute angle portion G, so that the number of cuts increases and the cost of the die increases.

[0012]

In order to solve the above problems, a floor mat for a construction machine according to the present application comprises a plurality of divided portions. Then, a joining portion for joining the divided portions is provided on the back surface side. Since the divided surfaces are joined by the joining portions, gaps and deviations are less likely to occur in the divided surfaces. Also, when viewed from the front side, the joint is hidden, so that the appearance is not impaired.

In another construction machine floor mat according to this application, a rib is provided along the end near the end corresponding to the cockpit entrance on the back surface. And
The rib is formed so that its lower end protrudes below the lower end of the rib provided on the back side inside the rib. Therefore, when floor mats for construction machinery are laid on floorboards in the cockpit of construction machinery,
The end corresponding to the entrance is raised by a rib along the end, forming an inclined surface near the end of the surface, eliminating the step at the lower part of the entrance.

[0014]
