JP-A-9-193703

  By the way, various devices such as an operation lever, an electronic device, and an air conditioner are disposed in the cab, and wiring materials and piping materials such as hydraulic piping and wiring cables are connected to each device. Since the space inside the cab is generally limited, if a wiring material or piping material is passed through the space between the cab floor surface and the back surface of the floor mat, it is effective for utilizing the space inside the cab. However, when a floor mat as described in Patent Document 1 is laid on the cab floor surface, a route through which the wiring material and the piping material pass (wiring and piping route) so that the wiring material and the piping material and the rib wall do not interfere with each other. It is necessary to take measures such as cutting the rib wall on the top.

However, if the wiring and piping route are different, the position of the rib wall to be cut is also different, so if the wiring and piping route are different due to differences in the model and specifications, it is necessary to prepare the floor mat for each model and specification. Standardization is difficult.
In addition, when it is desired to change the specifications of the wiring and the piping route, it is necessary to newly cut the rib wall using a cutting tool such as a cutter, and it is troublesome to change the specification, which is difficult to cope with.

  The present invention has been made in view of such problems. While forming the wiring and piping route on the back surface thereof, the present invention is excellent in vibration absorption and sound insulation performance, standardized with a simple configuration, and wired according to differences in models and specifications. An object of the present invention is to provide a floor mat for a work machine that can easily cope with different piping routes.

  In order to achieve the above object, a floor mat of a working machine according to the present invention according to claim 1 is laid on a floor surface of a cab of a working machine (for example, a construction machine, an agricultural tractor, a crane vehicle, etc.). It is a mat, and is formed by standing up in a lattice shape on the skin member (mat body) that horizontally covers the floor surface, and on the floor surface side of the skin member (that is, the back surface side of the skin member), A rib wall that reinforces the skin member, and a score formed on the rib wall along a predetermined shape are provided.

  The rib wall may be arranged in a grid pattern, a triangular grid, a hexagonal grid, or a complex grid combining these grids. It is good also as a shape. In addition, the notches may be formed in all rib walls that define each of the lattice shapes, and may be at least a passage for piping material or wiring material laid on the floor side of the skin member. You may form only in the rib wall standing at a position.

Further, the skin member and the rib wall are preferably made of a material having flexibility, elasticity, or flexibility, such as rubber, plastic, resin, or aluminum die-cast.
A floor mat for a work machine according to a second aspect of the present invention is the floor mat for the work machine according to the first aspect, wherein the notch is cut so that a part of the rib wall can be cut out along a predetermined shape. It is characterized by a cut line.

The cut line means that a portion cut, cut, or recessed in the thickness direction of the rib wall is provided intermittently in the surface direction of the rib wall.
A floor mat for a work machine according to a third aspect of the present invention is the floor mat for the work machine according to the second aspect, wherein the cut line is cut into an arch shape so as to be cut off.

A floor mat for a work machine according to a fourth aspect of the present invention is the floor mat for the work machine according to the first aspect, wherein the notches are formed in a straight line shape and can be folded and folded along the straight line. It is a fold line.
The folding line means that the portion cut, cut or recessed in the thickness direction of the rib wall is provided intermittently in the surface direction of the rib wall, or cut in the thickness direction of the rib wall. Or it means that the recessed part was provided continuously in the surface direction of the rib wall.

According to the floor mat of the work machine of the first aspect of the present invention, the grid-like rib wall can be easily cut or bent along the notches, so that the rib wall can be cut or cut at any plurality of rib walls. A space (lattice chamber) surrounded by the rib wall can be communicated by bending, and a passage (that is, wiring, piping route) can be freely formed on the back surface of the skin member.
Therefore, it is excellent in vibration absorption and soundproofing performance, and a space for wiring and piping route can be easily secured on the floor mat with a simple configuration.

In addition, in floor mats having rib walls with the same notches, the above-mentioned passages can be formed by appropriately cutting or bending any rib wall, so the floor mat can be flexibly adapted to changes in models and specifications. It can be standardized and manufactured with a simple configuration, and the manufacturing cost can be reduced.
Further, in the floor mat manufacturing process, a toolless manual cutting or bending operation can be performed to form a passage, thereby reducing and shortening the time and effort for manufacturing and changing specifications.

Even when a load is applied, the load acting on the rib wall can be sufficiently received by the rib wall that is not bent.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[One Embodiment]
1 to 3 illustrate a floor mat of a working machine according to an embodiment of the present invention. FIG. 1 is a perspective view showing the configuration of the floor mat. FIG. 2 is a view of the floor mat in a laid state. The perspective view which permeate | transmits and shows an outer skin member, FIG. 3 is the perspective view which saw through the inside of the cab by which this floor mat is laid.

<Configuration>
The floor mat 1 is a rug that absorbs vibrations in the feet of the cab of a work machine such as a construction machine or an agricultural tractor. Here, as shown in FIG. 3, the floor mat 1 is laid in a cab 10 of the work machine. Is illustrated.
The cab 10 is equipped with various devices such as an operator seat 11, an operation lever 12, and an electronic device 13, and wiring materials and piping materials connected to these devices do not interfere with driving operations. Further, it is disposed through the side space in the cab 10 and the vicinity of the floor surface 14. In the example shown in FIG. 3, the hydraulic piping material 15 connected to the operation lever 12 is disposed on the cab floor surface 14. The cab floor 14 has a flat surface that is flat in the horizontal direction. A flexible floor mat 1 is laid so as to cover the cab floor surface 14 in a planar shape substantially horizontally.

  As shown in FIG. 1, the floor mat 1 is integrally formed with a mat main body (skin member) 2 and a grid-like grid standing on the back surface of the mat main body 2 and reinforcing the mat main body 2 ( Rib wall) 3. The surface of the mat body 2 is formed with a concavo-convex shape as a non-slip. Note that the grid-like lattice shape means a grid shape in which straight lines that are orthogonal to each other are arranged at equal intervals.

The rib 3 is a combination of plate-like members arranged so as to form a wall in the vertical and horizontal directions, and the lattice chamber 4 is formed by being surrounded by the ribs 3 on the four sides.
The rib 3 has a notch (cut) 5 along a predetermined shape. The notches 5 here are cuts that are intermittently continued along a predetermined shape. In other words, the notches 5 are notched in a broken line shape when the wall surface of the rib 3 is viewed from the front. A cut line. Then, the cut may be cut so as to penetrate the wall of the rib 3 in the thickness direction, or may be cut to such an extent that it can be cut without penetrating the wall.

In addition, the notches (cut lines) 5 are formed in all the ribs 3 partitioning each lattice chamber 4 as shown in FIG. 2, and are inscribed in an arch shape projecting upward in an arc shape. . And the rib 3 can cut off the inside of the cutting line 5 along the cutting line 5, and can form the opening 6 in the wall surface.
The opening 6 is formed larger than the cross-sectional shape of the hydraulic piping material 15 and is opened to the cab floor 14 side. The adjacent lattice chambers 4 communicate with each other through the openings 6. The arch shape refers to a gate shape around the opening 6 formed in a curved shape so as to disperse a vertically downward load in the left-right direction of the opening 6.

<Action and effect>
Since the floor mat of the working machine according to the embodiment of the present invention is configured as described above, the following actions and effects are obtained.
The floor mat 1 is laid on the cab floor surface 14, and a hydraulic piping material 15 is piped on the cab floor surface 14.

  Therefore, as shown in FIG. 2, in the rib 3 at a position corresponding to the piping route of the hydraulic piping material 15, the inside of the cutting line 5 is cut along the cutting line 5 to form an opening 6 on the wall surface. According to this, the lattice chambers 4 communicated by the openings 6 are arranged along the piping route, and a passage corresponding to the piping route of the hydraulic piping material 15 can be easily and freely formed. Space can be secured. Further, since the rib 3 can be easily cut off by the cutting line 5 without using a tool, even if the cutting work is performed manually, it is possible to reduce and shorten the time and labor for changing the specifications. Furthermore, since a pipe route can be formed at an arbitrary location on the floor mat 1 by cutting off an arbitrary rib 3 with a cutting line 5, a space can be secured with a simple configuration, and flexibility in changing models and specifications is provided. There is an advantage of high.

Further, in the manufacturing process of the floor mat 1, since the cut lines 5 are formed in the same manner for all the ribs 3, it is possible to easily standardize and to reduce the manufacturing cost. is there.
Then, the floor mat 1 is laid so that the passage and the piping route of the hydraulic piping material 15 coincide.

At this time, since the size of the opening 6 of the rib 3 is set to be larger than the cross-sectional shape of the hydraulic piping material 15, the floor mat 1 is cabted without the inner peripheral surface of the opening 6 contacting the hydraulic piping material 15. It can be laid on the floor 14 and the hydraulic piping material 15 can be protected.
When the floor mat 1 is stepped on by an operator and a load is applied from above the floor mat 1, a large number of lattice chambers 4 are formed on the back surface of the mat body 2. Can bend elastically and absorb the load to improve the treading comfort.

  Here, in a place where the hydraulic piping material 15 is not piped, the rib 3 functions as a normal rib, so that the strength (stepping comfort) of the floor mat 1 can be ensured. On the other hand, even when the opening 6 is formed on the back surface of the mat body 2 that has been depressed, the opening 6 has an arch shape as shown in FIG. It can be distributed to the left and right of the opening 6 and transmitted to the remaining portion of the rib 3. Thereby, a load can be absorbed without changing the shape of the opening 6 almost, and the protection effect of the hydraulic piping material 15 can be improved more. At this time, even when a load is applied directly above the hydraulic piping material 15, as described above, the hydraulic piping material 15 does not interfere with the inner peripheral surface of the opening 6, and the load is applied to the hydraulic piping material 15. The hydraulic piping material 15 can be surely protected without doing so.

When vibration is transmitted from below the cab 10, the vibration is attenuated and absorbed by the rib 3, so that the vibration absorption and soundproofing properties of the cab floor surface 14 can be ensured satisfactorily.
In addition, in the conventional floor mat, the rib wall was cut to form the passage for the hydraulic piping material, so the load from the floor mat may directly affect the wiring material and piping material underneath, Although it was necessary to increase the strength of the hydraulic piping material itself, the floor mat 1 according to the present embodiment does not require such an advantage, and there is an advantage that the cost of the hydraulic piping material 15 can be reduced.

  In addition, since the opening 6 is open to the cab floor surface 14 side, the floor mat 1 can be easily laid or removed without moving the piping. For example, when the cab floor 14 is to be washed with water in order to clean dust and mud in the cab 10, the floor mat 1 can be easily removed by lifting it upward, and the floor mat 1 can be easily laid after cleaning. It is.

[Others]
Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the notch 5 (that is, the opening 6) of the rib 3 has an arch shape, but the shape of the notch 5 is not limited to this, and is, for example, a polygonal shape such as a triangular roof shape. Or a spindle shape.

Further, in the above-described embodiment, the score 5 is formed as a cut line, but may be formed as a fold line instead of the cut line.
That is, the rib 3 may be inscribed with a notch that can be bent and folded back along a predetermined shape. The notches here are fold lines that are cut in a broken line shape or a solid line shape when the wall surface of the rib 3 is viewed from the front.

  In the case of a fold line that has been cut in a broken line shape, the cuts are intermittently continued. In addition, the cut may be cut so as to penetrate in the thickness direction of the wall of the rib 3, or may be cut to such an extent that it can be bent without penetrating. However, when cutting through the rib 3 in the thickness direction, the interval between two adjacent cuts and the length of the cut are adjusted as appropriate so that the cut is not cut along the folding line. It has come to be.

On the other hand, in the case of a fold line that is cut in a solid line, the cuts are continuously connected. Further, the cut is made to such an extent that it can be bent without penetrating in the thickness direction of the rib 3.
Further, the folding line is formed in a linear shape on the rib 3. More specifically, each rib 3 has a pair of left and right cuts extending through the wall body and extending vertically. A fold line is formed in a straight line connecting the upper ends of the pair of cuts.

Then, by bending the rib 3 along the fold line, an opening similar to that of the above-described embodiment surrounded by the pair of left and right cuts and the fold line is formed on the wall surface of the rib 3.
Therefore, in an arbitrary rib 3 located at a position corresponding to the piping route, a part of the rib 3 is bent along a notch (folding line) to form an opening so that a passage corresponding to the piping route is provided on the back surface of the floor mat 1. Can be easily formed. Further, the floor mat 1 can be standardized with a simple configuration.

  Furthermore, when the wiring route is changed and the position of the bent rib 3 deviates from the wiring and piping route, the previously bent rib 3 can be restored (folded back). Even if the wiring and piping route specification changes are repeated, the location where the opening is formed in the rib 3 by bending is only the location corresponding to the current wiring route, so that a load acts from above the floor mat 1. In this case, the load acting on the rib can be sufficiently received by the rib 3 that is not bent.

Further, in the above-described embodiment, the ribs 3 have a grid-like lattice shape, but the lattice shape is not limited to this, and for example, a shape such as a triangular lattice or a hexagonal lattice may be used. Alternatively, it may be a complicated lattice shape in which these lattices are combined. This lattice shape is a design standard for wiring lines and piping lines.
Further, in the above-described embodiment, the notches 5 are formed in all the ribs 3, but are standing at a position that can serve as a passage for at least piping material (wiring material) laid on the back side of the mat body 2. It may be formed only on the rib 3. Even in this case, for example, if the piping route (wiring route) is fixed to some extent in advance, there is an effect that it can be easily standardized with high flexibility for changing the model and specifications as in the above-described embodiment. Further, since the notches 5 are not formed for all the ribs 3, there is an advantage that the manufacturing process of the floor mat 1 can be further shortened.

Further, in the above-described embodiment, the hydraulic piping material 15 is disposed on the cab floor surface 14, but not only the hydraulic piping material 15 but also wiring materials such as a wiring cable connected to the electronic device 13 and the air conditioner. Of course, the present invention can also be applied to the case where is disposed on the cab floor 15.
In the above-described embodiment, the floor mat 1 is laid in the cab 10 of the work machine. However, the floor mat 1 is applied as a floor mat to be laid in the cab of various work machines such as agricultural tractors and crane vehicles. Is possible.
