However, the annular ridge provided in the floor mat of Patent Document 1 is arranged to approach one of the operation pedals in front of the driver's seat, and the annular ridge interferes with the operation of the operation pedal by the occupant. As a result, the operability may deteriorate. In addition, for example, in the case where the driver's cab is covered with a canopy, when rainwater passing through the driver's seat enters the inside of the annular ridge of the floor mat in rainy weather, it is blocked by the annular ridge. A large amount of rainwater accumulates in the accommodation recess. Then, there is also the problem that the floor mat does not drain water well, and unsanitary conditions continue.

The present invention has been made in view of the above points, and its object is to accommodate a container in a position that does not interfere with a crew member when operating a construction machine, and to provide a water-draining machine. To provide a good floor mat for construction machinery.

In order to achieve the above object, the present invention is characterized in that the accommodation recess provided in the floor mat is arranged in a dead space, and a notch is provided in the annular ridge forming the accommodation recess.

Specifically, the following measures were taken for a flexible floor mat for construction machinery laid on the floor panel at the foot of the driver's seat.

A second invention is characterized in that, in the first invention, a convex portion is arranged close to the notch portion on the bottom surface of the accommodating concave portion.

In a third invention, in the first or second invention, the floor mat includes a front mat positioned on the front side of the vehicle from a dividing line extending over the entire width of the vehicle, and a front mat positioned on the rear side of the vehicle from the dividing line. and the front mat is formed with one or more holes for an operation lever or an operation pedal.

In a fourth aspect of the invention, in the third aspect, the dividing line is set to pass through the convex portion, and an engaging portion is provided at the rear mat side edge portion of the front mat. The front mat side edge of is provided with an engaged portion with which the engaging portion can be engaged and disengaged.

In a fifth aspect according to the fourth aspect, the engaging portion includes a first hook-shaped portion that opens upward and has a hook-shaped cross section that extends in the vehicle width direction, and the engaged portion extends downward. It is characterized by comprising a second hook-shaped portion which is open and extends in the vehicle width direction and which has a hook-shaped cross-section and can be engaged with the first hook-shaped portion from above.

In a sixth invention, in any one of the first to fifth inventions, the bottom surface of the housing recess has a shape that gradually slopes downward toward a position corresponding to the notch. It is characterized by

In a seventh aspect of the invention, in any one of the first to sixth aspects of the invention, the standing wall portion of the annular ridge portion on the side closer to the entrance/exit extends over the entire vehicle front-rear direction, and the standing wall The portion is characterized by being provided with a thin cuttable portion extending in the longitudinal direction of the vehicle.

In the first invention, the accommodation recess for accommodating the accommodation body is located in the dead space on the front side of the console box on the side of the driver's seat, so that the annular ridge does not interfere with the operation of the operation pedal by the occupant. Therefore, it is possible to prevent the operability of the construction machine from being degraded when the floor mat is laid on the floor panel. Also, even if a large amount of rainwater enters the storage recess during rainy weather, the rainwater is drained from the storage recess to the outside of the floor mat via the notch. Therefore, rainwater does not remain in the accommodation recesses for a long time, and the floor mat can be made to drain water well.

In the second invention, since most of the area corresponding to the notch in the accommodation recess is occupied by the projection, even if the container accommodated in the accommodation recess unexpectedly moves toward the notch, The container is caught in the gap between the projection and the notch. Therefore, even if the width dimension of the notch is set large, the container will not fall from the notch, so that the container can be reliably prevented from falling from the notch while improving the drainage performance in the notch of the containing recess. can be done.

Since only the front mat needs to be changed to a shape corresponding to the vehicle type, the floor mat can be made at a low cost.

In the fourth invention, since the engagement structure between the front mat and the rear mat is located on the vertically thick convex portion, the engagement structure has high rigidity, and the floor mat cannot be disassembled. It is possible to provide a floor mat that is less likely to be damaged or deformed even if it is repeatedly assembled.

In the fifth invention, the action of lifting the rear mat disengages the front mat, while the action of laying down the rear mat engages the front mat. In this manner, the floor mat can be laid on the floor panel while assembling the floor mat with relatively simple operations, and the burden of laying the floor mat on the worker can be reduced.

In the sixth aspect, all the rainwater collected in the storage recess moves toward the notch and is drained from the notch, so that the floor mat's ability to drain water can be further enhanced.

In the seventh aspect of the invention, when the floor mat is cut along the cuttable portion, the floor mat has a shape without the storage recess area. Therefore, for example, when the mold for forming the floor mat of the present invention is applied to a vehicle type in which a vehicle structure is arranged in the region on the front side of the console box next to the driver's seat, the floor mat is applied to the floor panel of the vehicle type. It can be easily changed to a corresponding shape.
