Meanwhile, a plurality of fourth fastening holes are formed in the fixed wall at a predetermined pitch along the circumferential direction centered on the first shaft, at positions corresponding to the plurality of third fastening holes in accordance with the rotation angle of the sole-resting member.

In this way, by forming multiple third fastening holes along the line connecting the first shaft and the first fastening hole in a direction away from the first shaft, the inclination angle of the sole-resting member, which is set at the pitch between the multiple second fastening holes, can be set even smaller.

The third fastening hole formed in the support piece, one of the multiple fourth fastening holes formed in the fixed wall, is aligned with the rotation angle of the sole-resting member. Then, with the third fastening hole and the fourth fastening hole aligned, fastening members are inserted through the third and fourth fastening holes, fastening the support piece to the fixed wall via the fastening members. This fixes the sole-resting member at a predetermined tilt angle.

The footrest device according to claim 8 is a footrest device according to any one of claims 1 to 7, further comprising a contacting/separating member that moves the heel resting member toward and away from the sole resting member.

FIG.

The following describes a footrest device according to an embodiment of the present invention, using the drawings. Note that the arrow FR shown in each drawing indicates the front of the footrest device, and the arrow UP indicates the top of the footrest device.

<Configuration of the footrest device>
First, the configuration of the footrest device according to this embodiment will be described.

As shown in FIG. 1, the foot rest device 10 of this embodiment is a device used for seat evaluation experiments, etc. In this embodiment, the foot rest device 10 is configured to include a sole rest portion (sole rest member) 12 and a heel rest portion (heel rest member) 14, with the sole rest portion 12 and heel rest portion 14 being provided independently.

The sole of the foot is placed on the sole resting portion 12, and the heel is placed on the heel resting portion 14. For this reason, the length of the sole resting portion 12 in the front-to-back direction is set to be longer than the length of the heel resting portion 14 in the front-to-back direction; in this case, the length of the sole resting portion 12 is approximately four times the length of the heel resting portion 14.

The sole resting portion 12 and heel resting portion 14 are provided with a rectangular base plate (second base plate) 16 and a base plate (first base plate) 18, respectively. The base plates 16 and 18 are each fixed to a base plate 20 (not shown) for conducting evaluation experiments of vehicle seats.

For this reason, mounting holes 16A are formed in the corners of base plate 16, and mounting holes 18A are formed in both longitudinal ends of base plate 18, allowing base plates 16, 18 to be attached to base plate 20 in an appropriate position via fastening members (not shown). Note that base plates 16, 18 have multiple mounting holes in addition to mounting holes 16A, 18A, allowing base plates 16, 18 to be attached to base plates for different vehicle models.

(Foot sole placement section)
Here, the sole resting portion 12 will be described.

A roughly U-shaped handle portion 22, which opens downward, is attached to the front and rear of the base plate 16 at both ends of the base plate 16 in the width direction perpendicular to the front-to-rear direction, by welding or the like. The sole-of-foot rest portion 12 can be lifted by grasping the handle portion 22.

A pair of axle plates 24, each roughly triangular in side view, are erected along the front-to-rear direction of the base plate 16 at the rear end 16B and both widthwise ends of the base plate 16, and a shaft (first axle portion) 26 is fixed to each axle plate 24.

On the other hand, the sole placement section 12 is provided with a rectangular sole placement plate 28 that can come into contact with the sole of the foot. Axle plates 30 are provided on both widthwise ends of the sole placement plate 28, facing the axle plate 24 provided on the base plate 16, and protrude toward the underside 28A of the sole placement plate 28. Axle holes 30A (see Figure 2) are formed in the axle plates 30, and a shaft 26 is inserted through the axle holes. The sole placement plate 28 can rotate around the shaft 26 via the axle plate 30, shaft 26, and axle plate 24.

The sole-placing portion 12 also includes a frame member 32 that forms the framework of the sole-placing portion 12 and is provided on the underside 28A of the sole-placing plate 28. The frame member 32 spans the width of the sole-placing plate 28 and prevents the sole-placing plate 28 from bending.

Support pieces 34 are provided on the free end of the sole-placing plate 28, extending from both widthwise ends of the sole-placing plate 28 toward the underside 28A of the sole-placing plate 28. The support pieces 34 have a generally rectangular frame shape in side view, and a plurality of third fastening holes 36 are formed at the tip of each support piece 34 at a predetermined pitch, extending away from the shaft 26.

These third fastening holes 36 are arranged on a line P (see Figure 2) that connects the shaft hole 30A (see Figure 2) through which the shaft 26 is inserted and the first fastening hole 36A, which is located on the shaft plate 24 side of the third fastening holes 36. A bolt (fastening member) 38 and a nut (fastening member) 39 are fastened to the first fastening hole 36A.

On the other hand, as shown in Figure 2, fixed walls 40, which are generally rectangular in side view, are erected on the base plate 16 on the front side of the pair of shaft plates 24, and a plurality of second fastening holes 42 are formed in the fixed walls 40 at a predetermined pitch in the circumferential direction around an axial hole (not shown) formed in the shaft plate 24 and through which the shaft 26 is inserted.

As shown in Figures 1 and 2, the pair of fixed walls 40 are arranged along the width direction of the sole-placing plate 28 so as to be outside the support pieces 34 provided on the sole-placing plate 28, and the multiple second fastening holes 42 are compatible with the first fastening holes 36A formed in the support pieces 34.

Furthermore, a bolt 38 is inserted into the second fastening hole 42 that corresponds to the first fastening hole 36A, and the support piece 34 is fastened to the fixed wall 40 by the bolt 38 and nut 39. As a result, the sole-supporting plate 28 is fixed at a predetermined inclination angle, as shown in Figures 2 and 3.

As mentioned above, the support piece 34 shown in FIG. 1 is formed with a plurality of third fastening holes 36. Therefore, to correspond to the plurality of third fastening holes 36, the fixed wall 40 is provided with a plurality of fourth fastening holes 44 at a predetermined pitch concentrically with a hole (not shown) formed in the axle plate 24 through which the shaft 26 is inserted, and in the circumferential direction around the hole.

Therefore, a bolt 38 is inserted into a fourth fastening hole 44 that corresponds to a specific third fastening hole 36 out of the multiple third fastening holes 36, and the support piece 34 is fastened to the fixed wall 40 by the bolt 38 and nut 39. As a result, the sole support plate 28 is fixed at a specified inclination angle.

In this embodiment, the base plate 16 is provided with an inclined member 46 on the back surface 28A side of the sole resting plate 28. This inclined member 46 is configured so that it is higher on the heel resting portion 14 side. One longitudinal end of the inclined member 46, which is aligned with the inclination direction of the inclined surface 46A, is integrated with the tip of a vertical wall portion 48 provided on the heel resting portion 14 side.

This creates an angle between the tilting member 46 and the base plate 16. The tilting member 46 also has a pair of through holes 50 formed along the tilted surface 46A. Bolts 52 can be engaged with these through holes 50.

Meanwhile, a pair of axle plates 54 are provided on the rear surface 28A of the sole-supporting plate 28, at both widthwise ends. These axle plates 54 are fixed to the frame member 32, and a pair of axle plates 56 are provided side by side in the widthwise direction of the sole-supporting plate 28.

A shaft (second shaft) 58 is fixed to this shaft plate 56. A pipe-shaped arm 60 formed in a roughly U-shape with an opening on the sole-placing plate 28 side is provided on the underside 28A of the sole-placing plate 28, and both ends 60A of the arm 60 are pivotally supported so as to be rotatable around the shaft 58. The center portion 60B of the arm 60 can abut against the inclined surface 46A of the inclined member 46.

In this way, the center portion 60B of the arm 60 abuts against the inclined surface 46A of the inclined member 46, thereby supporting the sole-of-foot resting plate 28 via the arm 60. The position of the inclined surface 46A of the inclined member 46 that the center portion 60B of the arm 60 abuts on changes depending on the inclination angle of the sole-of-foot resting plate 28, but this can be accommodated by rotating both ends 60A of the arm 60 around the shaft 58.

A bracket (fixing member) 62 can be attached to the tilting member 46. The bracket 62 is roughly inverted U-shaped in side view and includes a holding portion 64 that covers the arm 60 from the outside when it is in contact with the tilting member 46, and a pair of flange portions 66 that protrude outward from the tip of the holding portion 64 and come into contact with the inclined surface 46A of the tilting member 46.

The pair of flange portions 66 are each provided with fastening holes (not shown) that correspond to a pair of through holes 50 formed in the tilting member 46. Bolts 52 are inserted through the fastening holes and through holes 50 and fastened via nuts 70, thereby fixing the arm 60 to the tilting member 46 via the bracket 62.

The bracket 62 allows the bolt 52 to slide between itself and the side wall of the through hole 50, and before the bolt 52 is tightened against the nut 70, the sliding resistance between the bolt 52 and the side wall of the through hole 50 provides a so-called temporary fastening function.

This temporary fastening function is not limited to this. For example, it may be achieved by the sliding resistance between the central portion 60B of the arm 60 and the inclined surface 46A of the inclined member 46, or the temporary fastening state may be achieved by lightly tightening the bolt 52 against the nut 70.

(Heel resting area)
Next, the heel rest portion 14 will be described.

As shown in FIG. 5, a pair of fastening walls 72 are provided at both widthwise ends of the base plate 18. In plan view, these fastening walls 72 are generally U-shaped and open toward the center of the base plate 18 in the widthwise direction.

Furthermore, a rectangular heel support plate 74, which can come into contact with the heel, is fixed to the tip of the pair of fastening walls 72 by welding or other means. Slide members (contact and separation members) 76, 78 are fastened to the outside of the fastening walls 72, above and below the fastening walls 72, respectively.

Slide members 76 and 78 are each roughly L-shaped when viewed from the front. One end of slide member 78 is fixed to base plate 16 by welding or the like, and the other end is fastened to fastening wall 72. Slide member 76 has one end fixed to heel support plate 74 by welding or the like, and the other end is fastened to fastening wall 72.

Elongated holes 76A and 78A are formed in the slide members 76 and 78, respectively, along the front-to-rear direction of the heel rest plate 74. Bolts 80 and 82 are provided in the elongated holes 76A and 78A, respectively.

As a result, the position of the fastening wall 72 can be moved in the front-to-rear direction of the footrest device 10 relative to the base plate 18 via the elongated hole 78A and bolt 82 formed in the slide member 78. Furthermore, the position of the heel resting plate 74 can be moved in the front-to-rear direction of the footrest device 10 relative to the fastening wall 72 via the elongated hole 76A and bolt 80 formed in the slide member 76. In other words, the heel resting plate 74 can be moved toward and away from the sole resting plate 28.

<Actions and Effects of the Footrest Device>
Next, the operation and effect of the footrest device according to this embodiment will be described.

As shown in FIG. 1, in this embodiment, the foot rest device 10 includes a sole rest 12, a heel rest 14, a pair of support pieces 34, a pair of fixed walls 40, an inclined member 46, and an arm 60.

The base plate 16 of the sole resting portion 12, on which the sole of the foot is placed, and the base plate 18 of the heel resting portion 14, on which the heel is placed, are made of different members and are each fixed to the base plate 20. In this embodiment, the sole resting portion 12 and the heel resting portion 14 can be separated and adjusted separately.

The sole-supporting plate 28 provided on the sole-supporting portion 12 is rotatable around a shaft 26 fixed to an axle plate 24 provided on the base plate 16, and the angle formed between it and the heel-supporting plate 74 provided on the heel-supporting portion 14 is adjustable (for example, from approximately 20° to approximately 60°).

Meanwhile, a pair of support pieces 34 hang down from the underside 28A of the sole-placing plate 28 at the free end side of the sole-placing plate 28, and each support piece 34 is fixed to a pair of fixed walls 40 provided on the base plate 16 in accordance with the rotation angle of the sole-placing plate 28. In other words, the sole-placing plate 28 is supported via the pair of fixed walls 40 and the pair of support pieces 34.

The inclined member 46 is provided on the back surface 28A of the sole-placing plate 28 on the base plate 16, and is set so that the heel-placing section 14 side of the inclined member 46 is higher, creating an angle between the inclined member 46 and the base plate 16. The arm 60 is provided on the back surface 28A of the sole-placing plate 28, and abuts against the inclined surface 46A of the inclined member 46 to support the sole-placing plate 28 in accordance with the rotation angle of the sole-placing plate 28.

The arm 60 is also provided between a pair of support pieces 34. Therefore, in this embodiment, the sole support plate 28 is supported via a pair of fixed walls 40 and a pair of support pieces 34, and is also supported between the pair of support pieces 34 via the arm 60 and the inclined member 46.

In this way, in this embodiment, the arm 60 abuts against the inclined surface 46A of the inclined member 46 in accordance with the rotation angle of the sole-resting plate 28, thereby supporting the sole-resting plate 28. This eliminates the need to adjust the inclination angle of the sole-resting plate 28 while holding it with one hand, improving workability.

Meanwhile, a shaft 58 is provided on the underside 28A of the sole-of-foot resting plate 28 along the width direction of the sole-of-foot resting plate 28, and the arm 60 is rotatably supported by this shaft 58.

In this way, by rotating the arm 60 relative to the underside 28A of the sole-resting plate 28 via the shaft 58, in this embodiment, the arm 60 can be brought into stable contact with the inclined surface 46A of the inclined member 46 in accordance with the rotation angle of the sole-resting plate 28, thereby ensuring reliable support of the sole-resting plate 28.

In addition, in this embodiment, a bracket 62 is provided to secure the arm 60 in contact with the inclined surface 46A of the inclined member 46. This bracket 62 allows the arm 60 to be temporarily secured in place by, for example, sliding resistance between the bolt 52 and the side wall of the through hole 50 when the arm 60 is in contact with the inclined surface 46A of the inclined member 46.

This allows the arm 60 to be temporarily fixed when adjusting the inclination angle of the sole-rest plate 28. Once the inclination angle of the sole-rest plate 28 is set, the bolt 52 is tightened against the nut 70 to fix the arm 60.

In this embodiment, a fixed wall 40 is disposed on the outside of the support piece 34 along the width direction of the sole-resting plate 28. A first fastening hole 36A is formed in the support piece 34, and a plurality of second fastening holes 42 are formed in the fixed wall 40 at positions corresponding to the first fastening holes 36A at a predetermined pitch in accordance with the rotation angle of the sole-resting plate 28.

In other words, the first fastening holes 36A formed in the support piece 34 are aligned with the multiple second fastening holes 42 formed in the fixed wall 40 in accordance with the rotation angle of the sole-supporting plate 28. Then, with the first fastening holes 36A and the second fastening holes 42 aligned, bolts 38 are inserted into the first fastening holes 36A and the second fastening holes 42, and the support piece 34 and the fixed wall 40 are fastened together via the bolts 38 and nuts 39. This fixes the sole-supporting plate 28 at a predetermined tilt angle.

In addition, in this embodiment, a plurality of third fastening holes 36 are formed in the support piece 34 along a line P (see FIG. 2) connecting the shaft hole 30A (see FIG. 2), through which the shaft 26 is inserted, and the first fastening hole 36A, in a direction away from the shaft 26. Meanwhile, a plurality of fourth fastening holes 44 are formed in the fixed wall 40 at positions corresponding to the third fastening holes 36 at a predetermined pitch in accordance with the rotation angle of the sole support plate 28.

The third fastening holes 36 formed in the support piece 34, among the multiple fourth fastening holes 44 formed in the fixed wall 40, are aligned to match the rotation angle of the sole-supporting plate 28. Then, with the third fastening holes 36 and the fourth fastening holes 44 aligned, bolts 38 are inserted into the third fastening holes 36 and the fourth fastening holes 44, and the support piece 34 and fixed wall 40 are fastened together via the bolts 38 and nuts 39. This fixes the sole-supporting plate 28 at a predetermined tilt angle.

In this way, by forming multiple third fastening holes 36 along the line P connecting the shaft 26 and the first fastening hole 36A in a direction away from the shaft 26, the inclination angle of the sole support plate 28, which is set at the pitch between the multiple second fastening holes 42, can be set even smaller.

As described above, in this embodiment, the inclination angle of the foot rest plate 28 can be easily adjusted, and by setting the inclination angle of the foot rest plate 28 to a small value, it can be used to test vehicle seats of various vehicle types.

In other words, according to this embodiment, there is no need to prepare a footrest device 10 for each vehicle model. In other words, it is possible to test vehicle seats for various vehicle models using a single footrest device 10, which reduces the costs associated with developing the footrest device 10 and also contributes to saving space required for storing the footrest device 10.

In contrast, in this embodiment, as shown in FIG. 5, slide members 76, 78 are provided to move the heel resting plate 74 toward and away from the sole resting plate 28. This allows the slide members 76, 78 to move the heel resting plate 74 toward and away from the sole resting plate 28 when adjusting the inclination angle of the sole resting plate 28.

In other words, when adjusting the inclination angle of the sole resting plate 28, the heel resting plate 74 can be moved away from the sole resting plate 28 via the slide members 76, 78 to avoid interference between the heel resting plate 74 and the sole resting plate 28, or the heel resting plate 74 can be brought into contact with the sole resting plate 28 to eliminate any gaps between the heel resting plate 74 and the sole resting plate 28. However, this is not a limitation, as long as the heel resting plate 74 can be moved toward or away from the sole resting plate 28.

The present invention can be modified and implemented in various ways without departing from its spirit. It goes without saying that the scope of the present invention is not limited to the above-described embodiment.
