[0011] The following describes embodiments of the present invention with reference to the drawings, but the present invention is not limited thereto. The components of the embodiments described below can be combined as appropriate. In addition, some components may not be used.

[0012] [Embodiment] FIG. 1 is a perspective view of the driver's seat according to the embodiment as viewed from the upper left front. FIG. 2 is a plan view of the driver's seat according to the embodiment. FIG. 3 is a perspective view of the driver's seat according to the embodiment as viewed from the lower left rear. FIG. 4 is a partially enlarged view of FIG. 2. In the embodiment, the work machine is, for example, a forklift, a hydraulic excavator, or the like.

[0013] Hereinafter, the side where the driver's seat 1 of the work machine faces is the front, and the opposite side is the rear. In the embodiment, the left and right refer to the left and right with respect to the front. The left-right direction is the width direction of the driver's seat 1. The upper side is orthogonal to a plane (ground contact plane) that contacts at least three of the front wheels and rear wheels of the work machine (not shown), and is the side that faces from the ground contact plane toward the rotation center axis of the front wheel or the rear wheel. The lower side is the side that faces from the rotation center axis of the front wheel or the rear wheel toward the ground contact plane. An axis that extends in the front-rear direction of the vehicle body of the work machine and passes through the center in the vehicle width direction of the vehicle body is referred to as the front-rear axis, an axis that is orthogonal to the front-rear axis, parallel to the ground contact plane, and extends in the vehicle width direction of the vehicle body is referred to as the left-right axis. An axis that extends in the up-down direction of the vehicle body is referred to as the up-down axis. The up-down axis is orthogonal to both the front-rear axis and the left-right axis. The front-rear axis is the X axis, the up-down axis is the Y axis, and the left-right axis is the Z axis.

[0014] As shown in FIGS. 1 and 2, the driver's seat 1 is disposed on the floor plate 81 of the work machine. The floor plate 81 is disposed on a vehicle body frame of the work machine (not shown). The floor plate 81 is formed by processing a plate material. The floor plate 81 is located behind the foot plate 91 on which the operator places his or her feet in the front-rear direction and above in the up-down direction.

[0015] Figure 5 is a perspective view of the floor plate. In this embodiment, the floor plate 81 is configured to be attachable to driver's seats 1 of different shapes. The floor plate 81 is provided with first holes 82L1, second holes 82L2, first hole 82R1, second hole 82R2, first hole 83L1, second hole 83L2, first hole 83R1, and second hole 83R2 for attaching the slide rails 2 at positions corresponding to each of the different shaped driver's seats 1. The first holes 82L1, second holes 82L2, first hole 82R1, second hole 82R2, first hole 83L1, second hole 83L2, first hole 83R1, and second hole 83R2 pass through the floor plate 81. The first hole 82L1, the second hole 82L2, the first hole 82R1, the second hole 82R2, the first hole 83L1, the second hole 83L2, the first hole 83R1, and the second hole 83R2 are holes in the floor plate 81.

[0016] The first hole 82L1 and the second hole 82L2 are holes for attaching the slide rail 2L, corresponding to the driver's seat 1 with the shape shown in Figures 1 to 3. The first hole 82R1 and the second hole 82R2 are holes for attaching the slide rail 2R, corresponding to the driver's seat 1 with the shape shown in Figures 1 to 3. The first hole 82L1 and the second hole 82L2 are spaced apart in the front-rear direction. The first hole 82R1 and the second hole 82R2 are spaced apart in the front-rear direction. The first hole 82L1 and the first hole 82R1 are spaced apart in the left-right direction. The second hole 82L2 and the second hole 82R2 are spaced apart in the left-right direction.

[0017] The first hole 83L1 and the second hole 83L2 are holes for attaching the slide rail 2L, corresponding to the driver's seat 1 of a shape not shown. The first hole 83R1 and the second hole 83R2 are holes for attaching the slide rail 2R, corresponding to the driver's seat 1 of a shape not shown. The first hole 83L1 and the second hole 83L2 are spaced apart in the front-rear direction. The first hole 83R1 and the second hole 83R2 are spaced apart in the front-rear direction. The first hole 83L1 and the first hole 83R1 are spaced apart in the left-right direction. The second hole 83L2 and the second hole 83R2 are spaced apart in the left-right direction.

[0018] The spacing between the first hole 82L1 and the first hole 83L1, the spacing between the first hole 82R1 and the first hole 83R1, the spacing between the second hole 82L2 and the second hole 83L2, and the spacing between the second hole 82R2 and the second hole 83R2 are all only a few millimeters. For this reason, it is difficult to place back nuts on the underside of the floor plate 81 at the first hole 82L1, the second hole 82L2, the first hole 82R1, the second hole 82R2, the first hole 83L1, the second hole 83L2, the first hole 83R1, and the second hole 83R2, respectively.

[0019] A recess 89 is formed on the front side of the floor plate 81 and on the rear side of the foot plate 91 on which the operator places their feet. In this embodiment, a lid that can be opened and closed (not shown) is placed in the recess 89. The lid is a lid that can be opened and closed by rotating on its lower side as an axis. The recess 89 is recessed behind the wall portion 88 that connects the floor plate 81 and the foot plate 91. The upper surface of the recess 89 is the lower surface of the front part of the floor plate 81. The first holes 82L1, 82R1, 83L1, and 83R1 of the floor plate 81 penetrate through to the recess 89.

[0020] [Driver's seat] The driver's seat 1 comprises a seat portion 11 and a backrest portion 12. The seat portion 11 has a seat surface on which the operator sits. A pair of slide rails 2 are arranged on the underside of the seat portion 11. The backrest portion 12 is connected to the rear end of the seat portion 11. The backrest portion 12 is the part that serves as a backrest when the operator sits on the seat portion 11. The tilt angle of the backrest portion 12 is adjustable relative to the seat portion 11.

[0021] Figure 6 is a perspective view showing the slide rails arranged on the floor plate. Figure 7 is a perspective view of the slide rails. Figure 6 omits the illustration of the driver's seat 1. The slide rails 2 allow the driver's seat 1 to slide in the front-rear direction on the floor plate 81. As shown in Figure 3, a pair of slide rails 2 are arranged on the underside of the seat surface 11 of the driver's seat 1, spaced apart in the left-right direction. The slide rails 2 include slide rail 2L and slide rail 2R. Since slide rail 2L and slide rail 2R are similarly configured, the following description will focus on slide rail 2L. When there is no particular need to distinguish between slide rail 2L and slide rail 2R, they will be described as slide rail 2. In this embodiment, the slide rails 2 are configured to be attachable to driver's seats 1 of different shapes.

[0022] The slide rail 2 comprises a lower rail 21L and an upper rail 25L. The lower rail 21L and the upper rail 25L are slidably arranged.

[0023] The lower rail 21L is positioned on the upper surface of the floor plate 81. In this embodiment, the lower rail 21L is provided with multiple sets of mounting holes corresponding to the driver's seats 1 of different shapes. In this embodiment, the lower rail 21L is provided with first holes 22L1 and second holes 22L2 corresponding to the driver's seats 1 of the shapes shown in Figures 1 to 3, and first holes 23L1 and second holes 23L2 corresponding to the driver's seats of shapes not shown. The first holes 22L1 and second holes 22L2 are spaced apart in the front-rear direction. The first holes 23L1 and second holes 23L2 are spaced apart in the front-rear direction.

[0024] The upper rail 25L is slidable in the front-rear direction relative to the lower rail 21L. The upper rail 25L is positioned on the underside of the seat surface 11. In this embodiment, the upper rail 25L is provided with multiple sets of mounting holes 26L to accommodate the different shapes of the driver's seats 1. Bolts are inserted through the holes 26L and fastened to the underside of the seat surface 11.

[0025] In this embodiment, the holes in the slide rail 2 are the first hole 22L1, the second hole 22L2, the first hole 23L1, the second hole 23L2, the first hole 22R1, the second hole 22R2, the first hole 23R1, and the second hole 23R2.

[0026] The driver's seat 1 configured in this way includes a seat cushion 11, a backrest 12, a slide rail 2, and a mounting plate 3.

[0027] [Mounting plate] Figure 8 is a perspective view of the mounting plate. Figure 9 is a plan view showing the mounting plate assembled to the lower rail. Figure 10 is a cross-sectional view taken along line LL of Figure 9. The mounting plate 3 is used when attaching the driver's seat 1 to the floor plate 81. The mounting plate 3 is placed on top of the slide rail 2 which is stacked on top of the floor plate 81. More specifically, the mounting plate 3 is stacked on top of the lower rail 21 and fastened to the lower rail 21 of the slide rail 2 and the floor plate 81 by bolts 4. The mounting plate 3 is a component for fastening the lower surface of the lower rail 21 of the slide rail 2, which is the first surface of the first component, and the upper surface of the floor plate 81, which is the first surface of the second component, together with bolts 4. The mounting plate 3 is used for both the slide rail 2L and the slide rail 2R. The following description will focus on the mounting plate 3 for attaching the slide rail 2L. The mounting plate 3 for attaching the slide rail 2R has a similar configuration and will not be described.

[0028] The mounting plate 3 comprises a main body portion 31, a nut portion 32, a female screw portion 33, and a stopper portion 34. The main body portion 31 is formed in a plate shape. The main body portion 31 is positioned on the upper surface (second surface) opposite to the lower surface of the lower rail 21L of the slide rail 2L, with the lower surface of the lower rail 21L of the slide rail 2L and the upper surface of the floor plate 81 overlapped. The main body portion 31 is inserted into the space portion 2LS surrounded by the slide rail 2. The width d1 of the main body portion 31 is narrower than the width of the space portion 2LS of the slide rail 2L in the left-right direction. The width d1 of the main body portion 31 is narrower than, for example, about 1 mm than the width of the space portion 2LS in the left-right direction. The main body portion 31 is positioned on the lower rail 21L of the slide rail 2L. The main body portion 31 has a nut portion 32 having a female screw portion 33 provided on one side in the insertion direction of the main body portion 31. In this embodiment, the nut portion 32 is positioned at one end of the main body portion 31 in the insertion direction. The female threaded portion 33 formed in the nut portion 32 engages with the bolt 4 that fastens the slide rail 2L and the floor plate 81. The female threaded portion 33 engages with the bolt 4, which is inserted from the lower surface (second surface) opposite to the upper surface of the floor plate 81.

[0029] Space 2LS is a space enclosed in the left-right and up-down directions by the lower rail 21L and the upper rail 25L. Space 2LS is the space above the upper surface of the lower rail 21L and below the lower surface of the upper rail 25L. Space 2LS is open in the front-to-back direction.

[0030] A stopper portion 34 is positioned at the other end of the main body portion 31 in the insertion direction. The stopper portion 34 positions the main body portion 31 in the insertion direction relative to the space portion 2LS of the slide rail 2L. The stopper portion 34 has a width wider than the width d1 of the main body portion 31. The end portion 34a of the stopper portion 34 abuts against the other end portion 21La of the lower rail 21L of the slide rail 2 in the insertion direction. Abutment means that the end portion 34a of the stopper portion 34 abuts against the other end portion 21La of the lower rail 21L of the slide rail 2 in the insertion direction, thereby positioning it in the insertion direction.

[0031] When installing the driver's seat 1 as shown in Figures 1 to 3, with the end 34a of the stopper portion 34 in contact with the end 21La of the lower rail 21L of the slide rail 2L, the nut portion 32 corresponds to the first hole 22L1 of the lower rail 21L and the first hole 82L1 of the floor plate 81. In other words, the length d2 from the other end of the mounting plate 3 in the insertion direction to the center of the female screw portion 33 is the length of the nut portion 32 corresponding to the first hole 22L1 of the lower rail 21L and the first hole 82L1 of the floor plate 81, with the end 34a of the stopper portion 34 in contact with the end 21La of the lower rail 21L.

[0032] When installing a driver's seat 1 of a shape not shown, with the end 34a of the stopper portion 34 in contact with the end 21La of the lower rail 21L of the slide rail 2, the nut portion 32 corresponds to the first hole 23L1 of the lower rail 21L and the first hole 83L1 of the floor plate 81. In other words, the length d2 from the other end of the mounting plate 3 in the insertion direction to the center of the female screw portion 33 is the length of the nut portion 32 corresponding to the first hole 23L1 of the lower rail 21L and the first hole 83L1 of the floor plate 81, with the end 34a of the stopper portion 34 in contact with the end 21La of the lower rail 21L.

[0033] When installing a driver's seat 1 of the shape shown in Figures 1 to 3, the bolt 4 is inserted from the underside of the floor plate 81 into the hole in the slide rail 2 and the hole in the floor plate 81, with the two holes overlapping. When installing a driver's seat 1 of a shape not shown, the bolt 4 is inserted from the underside of the floor plate 81 into the first hole 22L1 of the slide rail 2 and the first hole 82L1 of the floor plate 81, with the two holes overlapping.

[0034] [How to install the driver's seat] This section describes the installation method for attaching the driver's seat 1 to the floor plate 81. Before attaching the driver's seat 1 to the floor plate 81, the pair of slide rails 2L and 2R are attached to the underside of the seat surface 11 of the driver's seat 1. The following description assumes that the driver's seat 1 is of the shape shown in Figures 1 to 3.

[0035] First, the process of attaching the rear of the slide rail 2 to the floor plate 81 will be explained. As shown in Figures 1 and 2, the driver's seat 1 is placed on the floor plate 81. The backrest portion 12 of the driver's seat 1 is tilted forward toward the seat portion 11. The driver's seat 1 is slid forward by the slide rail 2. When the driver's seat 1 is slid forward, as shown in Figure 4, the second holes 22L2, 22R2, 23L2, and 23R2 are exposed.

[0036] Align the first hole 22L1 of the slide rail 2L with the first hole 82L1 of the floor plate 81, and align the second hole 22L2 of the slide rail 2L with the second hole 82L2 of the floor plate 81. With the second hole 22L2 of the slide rail 2L aligned with the second hole 82L2 of the floor plate 81, fasten the two holes by inserting a bolt (not shown) through the second hole 22L2 and the second hole 82L2.

[0037] Align the first hole 22R1 of the slide rail 2R with the first hole 82R1 of the floor plate 81, and align the second hole 22R2 of the slide rail 2R with the second hole 82R2 of the floor plate 81. With the second hole 22R2 of the slide rail 2R aligned with the second hole 82R2 of the floor plate 81, fasten the two holes by inserting bolts (not shown) through the second holes 22R2 and 82R2.

[0038] Next, the process of attaching the front of the slide rail 2 to the floor plate 81 will be described. Figure 11 is a diagram illustrating the method of installing the driver's seat. Figure 12 is a diagram illustrating the method of installing the driver's seat. The driver's seat 1 is slid to the rear by the slide rail 2.

[0039] The mounting plate 3 is inserted into the space 2LS of the slide rail 2L. The mounting plate 3 is inserted until the end 34a of the stopper portion 34 abuts against the end 21La of the lower rail 21L of the slide rail 2. The nut portion 32 of the mounting plate 3 inserted into the space 2LS is located in the first hole 22L1 of the slide rail 2L and the first hole 82L1 of the floor plate 81. The bolt 4 is inserted into the nut portion 32, the first hole 22L1 of the slide rail 2L, and the first hole 82L1 of the floor plate 81 and fastened. The bolt 4 is inserted from the recess 89 located on the front side of the floor plate 81 and on the rear side of the foot plate 91.

[0040] The mounting plate 3 is inserted into the space 2RS of the slide rail 2R. The mounting plate 3 is inserted until the end 34a of the stopper portion 34 abuts against the end 21Ra of the lower rail 21R of the slide rail 2. The nut portion 32 of the mounting plate 3 inserted into the space 2RS is located in the first hole 22R1 of the slide rail 2R and the first hole 82R1 of the floor plate 81. The bolt 4 is inserted into the nut portion 32, the first hole 22R1 of the slide rail 2R, and the first hole 82R1 of the floor plate 81 and fastened. The bolt 4 is inserted from the recess 89 located on the front side of the floor plate 81 and the rear side of the foot plate 91.

[0041] In this manner, the driver's seat 1 is installed by placing the mounting plate 3 on top of the lower rail 21, aligning the holes in the slide rail 2 with the holes in the floor plate 81, inserting the bolt 4 from the underside of the floor plate 81, and screwing the bolt 4 into the female threaded portion 33 of the mounting plate 3 to attach the slide rail 2 to the floor plate 81.

[0042] [effect] As described above, in this embodiment, the mounting plate 3 is placed on top of the slide rail 2 which is stacked on top of the floor plate 81. In this embodiment, the bolt 4 is inserted from the underside of the floor plate 81 with the holes in the slide rail 2 and the holes in the floor plate 81 aligned. According to this embodiment, the slide rail 2 can be easily attached to the floor plate 81 by the mounting plate 3 and the bolt 4. In this embodiment, since the bolt 4 is inserted from the underside of the floor plate 81, it can be easily attached compared to the case where the bolt is inserted from the gap between the driver's seat 1 and the slide rail 2. In this embodiment, since the bolt 4 is inserted from the underside of the floor plate 81, it can be easily attached even if the gap between the driver's seat 1 and the slide rail 2 is narrow. In this embodiment, since the bolt 4 is inserted from the underside of the floor plate 81, it can be easily attached even if the space around the driver's seat 1 is narrow.

[0043] In this embodiment, the main body 31 of the mounting plate 3 is positioned on top of the upper surface of the slide rail 2, with the lower surface of the slide rail 2 and the upper surface of the floor plate 81 overlapping. The female threaded portion 33 of the mounting plate 3 is screwed into a bolt 4 inserted from the lower side opposite to the upper surface of the floor plate 81. According to this embodiment, the slide rail 2 can be easily attached to the floor plate 81 using the mounting plate 3.

[0044] In this embodiment, the stopper portion 34 of the mounting plate 3 abuts against the other end of the slide rail 2 in the insertion direction. According to this embodiment, the mounting plate 3 can be inserted and installed to the appropriate position without having to align it with the slide rail 2.

[0045] In this embodiment, the width d1 of the main body 31 of the mounting plate 3 is narrower than the width of the space 2S enclosed by the slide rail 2. According to this embodiment, the mounting plate 3 can be easily inserted into the space 2S of the slide rail 2.

[0046] In this embodiment, the length from the other end of the stopper portion 34 in the insertion direction to the center of the female thread portion 33 is such that, with the stopper portion 34 in contact with the other end of the slide rail 2 in the insertion direction, the length of the nut portion 32 corresponds to the length of the hole in the slide rail 2 and the hole in the floor plate 81. According to this embodiment, the mounting plate 3 can be installed in the appropriate position without having to align it with the slide rail 2 and the floor plate 81.

[0047] Figure 14 is a plan view of a conventional driver's seat. Figure 15 is an exploded perspective view illustrating the assembly method of a conventional driver's seat. When attaching the front part of the slide rail (not shown) to the floor plate 81X, the driver's seat 1 is slid as far back as possible to expose the front of the slide rail. However, due to the limited space in the driver's cab, the amount of movement the driver's seat 1 can move backward is also limited. As a result, the front part of the slide rail is not exposed, making it difficult to attach the slide rail to the floor plate 81X using tools. Therefore, in the conventional driver's seat 1, the slide rail is not directly attached to the floor plate 81X, but rather indirectly attached to the floor plate 81X using an intermediate plate 100X.

[0048] The intermediate plate 100X is formed by processing a plate material having an area approximately the same as the seat surface 11 of the driver's seat 1. When viewed in the vertical direction, at least a portion of the intermediate plate 100X protrudes from the seat surface 11 of the driver's seat 1. The intermediate plate 100X is positioned between the driver's seat 1 and the floor plate 81. The lower side of the seat surface 11 of the driver's seat 1 is attached to the intermediate plate 100X by bolts 110X. The intermediate plate 100X is attached to the floor plate 81 by bolts 110X.

[0049] In contrast, in this embodiment, the driver's seat 1 can be directly and firmly attached to the floor plate 81 without using the conventional intermediate plate 100X. In this embodiment, since the conventional intermediate plate 100X is not used, the number of parts can be reduced. As a result, in this embodiment, since there is no plate thickness of the intermediate plate 100X, the height of the seat reference point of the driver's seat 1 can be kept low. In this embodiment, since the intermediate plate 100X does not protrude around the driver's seat 1, space can be saved.

[0050] The embodiment allows for the installation of driver's seats 1 of different shapes.

[0051] [Differentiation] Figure 13 is a perspective view of a modified mounting plate. The nut portion 32 only needs to be positioned at a distance from the stopper portion 34 in the insertion direction of the main body portion 31.
