DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor mat for an operator's cab, which is suitable for use in construction equipment such as a hydraulic excavator.

[0002]

2. Description of the Related Art In general, in a cab of a construction machine of this type, a rubber floor mat is laid on a floor surface to receive earth and sand or mud brought into the room by a driver. The floor mat usually has a non-slip uneven surface on its surface, and has an opening for projecting an operating device such as a steering pedal and a footrest provided on the floor.

However, in the conventional floor mat structure,
Because the surface has many convex parts and the surface is formed as a horizontal surface as a whole, cleaning water and earth and sand for cleaning do not flow smoothly when the floor mat surface at the feet of the driver who is particularly dirty is washed with water, There was a problem that the cleaning work could not be easily performed because of the stay on the surface.

[0004] In order to cope with such a problem, the present applicant has formed a portion corresponding to the front side of the driver's cab on an inclined surface having a downward slope toward the rear, so that the earth and sand and the cleaning water can be smoothly rearward. There has already been proposed a floor mat structure in which the fluid flows out to the side and is easily discharged to the outside of the driver's cab.
00-136546).

[0005]

By the way, in the conventional cab structure, there is a partition wall perpendicular to the floor surface at the front end of the seat below the driver's seat, and the structure has a free space below the driver's seat. Not. For this reason, as described in the above publication, the floor mat has a configuration in which the rear end is located at the front end of the sheet. There is a necessity of a configuration in which the slope is formed on the downward slope.

However, recently, there has been a demand to increase the space around the driver's feet in order to further improve the comfort of the driver who operates the construction machine. For this reason, a free space is secured below the driver's seat. There is a need to do so. In order to meet such demands, it is necessary to extend the floor mat to a space below the newly formed driver's seat, which raises a new problem of discharge of sediment and cleaning water on the floor mat surface. It is supposed to happen.

Further, in the above-mentioned conventional floor mat structure,
Openings for projecting operating devices such as steering pedals and footrests are separately provided, and there is also a problem that a narrow space between these openings cannot be easily cleaned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is capable of smoothly discharging earth and sand and cleaning water on a mat surface to the outside of a driver's cab, thereby facilitating washing with water. It is an object of the present invention to provide a room floor mat.

[0009]

In order to achieve the above object, a driver's cab floor mat according to the present invention is a driver's cab floor mat laid on the floor of a driver's cab, A flow slope is formed on the floor mat surface toward the front of the cab so that the cleaning water sprinkled on the surface flows toward the door opening side of the cab (first invention). .

[0010] According to the present invention, the surface of the rear portion of the floor mat extending to the space below the driver's seat is formed so as to slope down toward the door opening side of the cab, in other words, toward the front. Therefore, when the surface of the floor mat is washed with water, the earth and sand and the cleaning water can smoothly flow forward and can be easily discharged from the cab door to the outside of the cab.

[0011] In the floor mat of the present invention, the flow slope is inclined such that the front surface of the floor mat at the front and rear of the driver's cab is made higher and becomes gradually lower toward the center in the front-rear direction of the floor mat. It is preferable that the cleaning water be collected toward the central portion and discharged from a door opening on the side of the cab (second invention). By doing so, the cleaning water can be collected at the center side of the cab, and can be smoothly discharged from the door opening.

Further, the surface of the floor mat opposite to the door opening on the side of the driver's cab is raised, and the surface of the floor mat is inclined so as to gradually decrease toward the door opening on the driver's cab side to collect the cleaning water on the door opening side. It is preferable to form a flow surface (third invention). By doing so, it is possible to form the flow of earth and cleaning water toward the door opening side of the driver's cab even in the left-right direction of the driver's cab, and there is an effect that the soil and cleaning water can be discharged more smoothly. .

It is preferable that a plurality of anti-slip projections are formed on the surface of the floor mat in a substantially arc shape in plan view (a fourth invention). In this case, with respect to the width of the convex portion,
It is preferable that the width of the concave portion between the adjacent convex portions is wider (fifth invention), and thereby, it is possible to avoid occurrence of a problem that sediment or the like accumulates in these concave portions. In addition, smoother discharge of cleaning water and the like can be realized.

Further, the extension of one end of the projection is directed toward the door opening of the cab (the sixth invention).
It is more preferable that a flow of cleaning water or the like in the direction of the door of the cab can be formed by these convex portions. Further, it is preferable that an extension line on one end side of the projection is directed obliquely forward (seventh invention). This makes it possible to more reliably form the flow of cleaning water and the like toward the lower part of the inclined surface.

In each of the above inventions, it is preferable that the footrest portion and the cover portion for the steering pedal are provided integrally (the eighth invention). By adopting such a configuration, cleaning around the footrest portion can be easily performed, and the feet of the driver can always be kept in a clean state.
