Description

[Detailed Description of the Invention] The present invention relates to a step device for a vehicle, which prevents the vibration of the step from being transmitted to the driver, and also reliably blocks noise that enters between the step and its adjacent members. The aim is to improve livability.

For example, in some tractors with a cabin, the cabin is built by placing a pine on the step that closes the bottom of the cabin. This was felt by the driver, and the ride was extremely uncomfortable. Additionally, gaps are created between the pine and adjacent members (e.g. fenders) adjacent to the step, which are not only unsightly but also
External noise penetrated into the cabin between the step and the adjacent member, and this also made the ride uncomfortable.

The present invention solves the above-mentioned problems, and its feature is that in a vehicle that is provided with a step so as to close the lower part of the cabin, on the step,
A mat having a large number of elastic ribs projecting downward is provided, and a sealing material is provided around the mat to close the gap between the mat and an adjacent member adjacent to the step.

Hereinafter, the present invention will be described according to the illustrated embodiments. In FIGS. 1 to 8, reference numeral 1 denotes a tractor body, which has front wheels 2 and rear wheels 3. 4 is a hood, 5 is an instrument panel, 6 is a steering handle, and 7 is a pair of left and right fenders that cover the inside and upper side of the rear wheels 3. Reference numeral 8 designates a hydraulic system for lifting and lowering the working machine, which has a pair of left and right lift arms 9, and 10 represents a driver's seat disposed above the hydraulic system 8. A cabin 11 is provided to cover the driver's seat 10, etc., and is comprised of a top wall 12, left and right side walls 13, a front wall 14, and a rear wall 15, and a door 16 for getting on and off is attached to the side wall 13 so as to be openable and closable. There is. Reference numeral 17 represents a cover that covers the upper side of the vehicle body 1, and reference numeral 18 represents a floor sheet, which is curved in an S-shape on its side, with its middle portion covering the hydraulic device 8, and its left and right front ends protruding downward. Reference numeral 19 denotes a pair of left and right steps provided horizontally on both sides of the vehicle body 1, the inner end of which is fixed to the cover 17 with a fixing device such as a bolt, and the outer end thereof is fixed to the lower end of the fender 7 with a fixing device such as a bolt. The lower end of the front end of the floor sheet 18 is attached to the rear end of the step 19.
A cover 17, a floor sheet 18, a fender 7, a door 16 for getting on and off the cabin 11, and a front wall 14 are adjacent to the step 9, and these surround the step 19. 20 is a mat provided on step 19;
The mat 20 is made of an elastic material such as rubber, and has a rectangular plate-shaped mat body 21 that extends over almost the entire area of the step 19, and a large number of mat bodies that protrude downward in a lattice pattern from the bottom surface of the mat body 21 over the entire area. The mat main body 21 is placed on the step 19 via the elastic ribs 22. Reference numeral 23 denotes a sealing material fixedly provided around the entire periphery of the mat 23, and is formed into a cylindrical shape from an elastic material such as rubber. 7 and the passenger door 16 of the cabin 11, the front part 26 is attached to the front wall 14 of the cabin 11, and the rear part 27 is attached to the floor seat 18.
They are in close contact with the front end portions over the entire length, and close the spaces between the mat 20 and the cover 17, the floor sheet 18, the fender 7, the door 16 for getting on and off, and the front wall 14.

According to the configuration of the above embodiment, vibrations are transmitted from the tractor body 1 to the step 19, and the vibration is transmitted from the tractor body 1 to the step 19.
Even if the mat main body 21 vibrates violently, the large number of elastic ribs 22 elastically deform in accordance with the vibration of the step 19, effectively absorbing and mitigating the vibration.
Almost no vibration is transmitted to the
9 will no longer be transmitted to the driver via the mat 20. In addition, since the sealing material 23 closes the space between the mat 20 and the cover 17, floor sheet 18, fender 7, passenger door 16, and front wall 14, the conventional unsightliness is solved, and the sealing material 23 , external noise entering the cabin 11 from between the step 19 and adjacent members such as the fender 7 can be reliably blocked.

FIG. 4 shows another embodiment, in which a sealing material 23 made of an elastic material is protruded in the shape of a fin so as to be in close contact with adjacent members such as the cover 17 and fender 18 over the entire circumference of the pine 20. It is set up. The other points are the same as in the previous embodiment, and the same effects are achieved.

In the embodiment, the elastic rib 22 is
1 in a lattice shape, but may alternatively be in a tortoiseshell or dotted shape.

According to the present invention, since a mat having a mat main body and a large number of elastic ribs projecting downward is provided on the step, even if the step vibrates violently,
Since the vibrations are effectively absorbed and alleviated by the elastic deformation of the elastic ribs, the vibrations of the steps are hardly transmitted to the mat main body, resulting in a comfortable ride for the driver. Also, around the pine,
Since a sealing material is provided to close the gap between the mat and the adjacent member adjacent to the step, the gap between the mat and the adjacent member, which was conventionally unsightly, can be eliminated, making it possible to create a beautiful appearance. The material reliably isolates noise from entering between the step and its adjacent members, resulting in a very comfortable ride.
