DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, a footrest device according to an embodiment of the present invention will be described with reference to the drawings. Note that an arrow FR shown in each drawing indicates the front of the footrest device, and an arrow UP indicates the top of the footrest device.

[0035] <Footrest device configuration> First, the configuration of the footrest device according to this embodiment will be described.

[0036] As shown in Fig. 1, the foot resting device 10 of this embodiment is a device used for seat evaluation experiments, etc. In this embodiment, the foot resting device 10 includes a sole resting portion (sole resting member) 12 and a heel resting portion (heel resting member) 14, and the sole resting portion 12 and the heel resting portion 14 are provided independently of each other.

[0037] 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;

[0038] The sole resting portion 12 and the heel resting portion 14 are provided with a rectangular base plate (second base plate) 16 and a base plate (first base plate) 18, respectively, and the base plates 16 and 18 are each fixed to a base plate 20 (not shown) for conducting evaluation experiments of vehicle seats.

[0039] 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, so that base plates 16, 18 can be attached to surface plate 20 in appropriate positions via fastening members (not shown). Note that base plates 16, 18 have multiple mounting holes in addition to mounting holes 16A, 18A, so that base plates 16, 18 can be attached to surface plates of different vehicle models.

[0040] (Foot sole resting area) Here, the sole resting portion 12 will be described.

[0041] At both ends of the base plate 16 provided on the sole-placing portion 12 in the width direction perpendicular to the front-rear direction, roughly U-shaped handles 22 with openings on the lower side are provided by welding or the like to the front and rear of the base plate 16. By gripping these handles 22, the sole-placing portion 12 can be lifted.

[0042] A pair of shaft plates 24, each having an approximately triangular shape when viewed from the side, are erected at the rear end 16B and both widthwise ends of the base plate 16 along the front-to-rear direction of the base plate 16, and a shaft (first shaft portion) 26 is fixed to each shaft plate 24.

[0043] On the other hand, the sole-placing portion 12 is provided with a rectangular sole-placing plate 28 that can come into contact with the sole of the foot. Axle plates 30 that protrude toward the rear surface 28A of the sole-placing plate 28 are provided on both widthwise ends of the sole-placing plate 28 that face the axle plate 24 provided on the base plate 16. Axle holes 30A (see FIG. 2) are formed in the axle plates 30, and a shaft 26 is inserted through the axle holes, so that the sole-placing plate 28 can rotate about the shaft 26 via the axle plate 30, the shaft 26, and the axle plate 24.

[0044] The sole-placing portion 12 also includes a frame member 32 that constitutes the framework of the sole-placing portion 12 and is provided on the rear surface 28A side of the sole-placing plate 28. The frame member 32 spans across the width of the sole-placing plate 28, and suppresses bending deformation of the sole-placing plate 28.

[0045] Support pieces 34 are provided on the free end side of the sole-placing plate 28, protruding from both ends in the width direction of the sole-placing plate 28 and toward the rear surface 28A side of the sole-placing plate 28. The support pieces 34 have a substantially rectangular frame shape in a side view, and a plurality of third fastening holes 36 are formed at the tip end of the support piece 34 at a predetermined pitch toward the direction away from the shaft 26.

[0046] The plurality of third fastening holes 36 are arranged on a line P (see FIG. 2) connecting an axial hole 30A (see FIG. 2) through which the shaft 26 is inserted and a first fastening hole 36A, which is located on the axial plate 24 side of the plurality of third fastening holes 36. A bolt (fastening member) 38 and a nut (fastening member) 39 are fastened to the first fastening hole 36A.

[0047] On the other hand, as shown in Figure 2, fixed walls 40 having an approximately rectangular shape 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 centered on an axial hole (not shown) formed in the shaft plate 24 and through which the shaft 26 is inserted.

[0048] 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 can correspond to the first fastening holes 36A formed in the support pieces 34.

[0049] Furthermore, among the multiple formed second fastening holes 42, 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 the nut 39. As a result, the sole-supporting plate 28 is fixed at a predetermined inclination angle, as shown in Figures 2 and 3.

[0050] 1 is formed with a plurality of third fastening holes 36. Therefore, in order to correspond to the plurality of third fastening holes 36, the fixed wall 40 is provided with a plurality of fourth fastening holes 44 on a concentric circle of a hole portion (not shown) formed in the axle plate 24 and through which the shaft 26 is inserted, and at a predetermined pitch along the circumferential direction around the hole portion.

[0051] Therefore, among the multiple third fastening holes 36 formed, a bolt 38 is inserted into a fourth fastening hole 44 corresponding to a predetermined third fastening hole 36, and the support piece 34 is fastened to the fixed wall 40 by the bolt 38 and the nut 39. In this way, the sole-supporting plate 28 is fixed at a predetermined inclination angle.

[0052] In this embodiment, the base plate 16 is provided with an inclined member 46 on the rear surface 28A side of the sole-resting plate 28. This inclined member 46 is set so that it is higher on the heel-resting portion 14 side. One end of the inclined member 46 in the longitudinal direction along 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.

[0053] As a result, an angle is provided between the inclined member 46 and the base plate 16. A pair of through holes 50 is formed along the inclined surface 46A in the inclined member 46. Bolts 52 can be engaged with the through holes 50.

[0054] Meanwhile, a pair of shaft plates 54 are provided on both widthwise ends of the rear surface 28A of the sole-resting plate 28. The shaft plates 54 are fixed to the frame member 32, and a pair of shaft plates 56 are provided side by side in the widthwise direction of the sole-resting plate 28.

[0055] A shaft (second shaft portion) 58 is fixed to the shaft plate 56. A pipe-like arm 60 formed in a substantially U-shape with an opening on the sole-placing plate 28 side is provided on the back surface 28A side of the sole-placing plate 28, and both end portions 60A of the arm 60 are pivotally supported so as to be rotatable around the shaft 58. A central portion 60B of the arm 60 is capable of coming into contact with the inclined surface 46A of the inclined member 46.

[0056] In this way, the center portion 60B of the arm 60 abuts against the inclined surface 46A of the inclined member 46, and the sole-of-foot-resting plate 28 is supported via the arm 60. The position of the inclined surface 46A of the inclined member 46, with which the center portion 60B of the arm 60 abuts, changes in accordance with the inclination angle of the sole-of-foot-resting plate 28, but this can be accommodated by rotating both end portions 60A of the arm 60 around the shaft 58.

[0057] A bracket (fixing member) 62 can be attached to the inclined member 46. The bracket 62 has a generally inverted U-shape in side view, and includes a holding portion 64 that covers the arm 60 from the outside when it is in contact with the inclined 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 inclined member 46.

[0058] The pair of flange portions 66 are provided with fastening holes (not shown) that correspond to the pair of through holes 50 formed in the tilting member 46. Bolts 52 are inserted into the fastening holes and the through holes 50 and fastened via nuts 70, thereby fixing the arm 60 to the tilting member 46 via the bracket 62.

[0059] In addition, the bracket 62 is configured so that, for example, the bolt 52 can 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.

[0060] 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 state in which the bolt 52 is lightly fastened against the nut 70 may be the temporary fastening state.

[0061] (Heel rest area) Next, the heel rest portion 14 will be described.

[0062] 5, a pair of fastening walls 72 are provided at both widthwise ends of the base plate 18. The pair of fastening walls 72 are generally U-shaped in plan view, opening toward the center of the base plate 18 in the widthwise direction.

[0063] Additionally, a rectangular heel rest plate 74 that can come into contact with the heel is fixed by welding or the like to the tip of the pair of fastening walls 72. Slide members (contact and separation members) 76, 78 are fastened to the outside of the fastening wall 72 above and below the fastening wall 72, respectively.

[0064] The slide members 76 and 78 are each substantially L-shaped when viewed from the front. One end of the slide member 78 is fixed to the base plate 16 by welding or the like, and the other end is fastened to the fastening wall 72. The slide member 76 has one end fixed to the heel rest plate 74 by welding or the like, and the other end is fastened to the fastening wall 72.

[0065] Here, the slide members 76, 78 are respectively formed with elongated holes 76A, 78A that extend along the front-rear direction of the heel rest plate 74. Bolts 80, 82 are provided in the elongated holes 76A, 78A, respectively.

[0066] Therefore, 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 the bolt 82 formed in the slide member 78. Also, 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 the 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.

[0067] <Actions and effects of the footrest device> Next, the operation and effects of the footrest device according to this embodiment will be described.

[0068] As shown in FIG. 1, in this embodiment, the foot rest device 10 includes a sole resting portion 12, a heel resting portion 14, a pair of support pieces 34, a pair of fixed walls 40, an inclined member 46, and an arm 60.

[0069] 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 a base plate 20. In this embodiment, the sole resting portion 12 and the heel resting portion 14 can be separated and adjusted separately.

[0070] In addition, the sole resting plate 28 provided on the sole resting portion 12 is rotatable around a shaft 26 fixed to an axis plate 24 provided on the base plate 16, and the angle formed between it and the heel resting plate 74 provided on the heel resting portion 14 is adjustable (for example, from about 20° to about 60°).

[0071] On the other hand, a pair of support pieces 34 hang down from the rear surface 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.

[0072] The inclined member 46 is provided on the rear surface 28A side of the sole-placing plate 28 on the base plate 16, and is set so that the heel-placing portion 14 side of the inclined member 46 is higher, forming an angle with the base plate 16. The arm 60 is provided on the rear surface 28A side 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.

[0073] The arm 60 is provided between the pair of support pieces 34. Therefore, in this embodiment, the sole-placing plate 28 is supported via the pair of fixed walls 40 and the 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.

[0074] 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-placing plate 28, thereby making it possible to support the sole-placing plate 28. Therefore, there is no need to adjust the inclination angle of the sole-placing plate 28 while holding it with one hand, improving workability.

[0075] On the other hand, a shaft 58 is provided on the rear surface 28A side of the sole-placing plate 28 along the width direction of the sole-placing plate 28, and an arm 60 is rotatably supported by the shaft 58.

[0076] In this way, by rotating the arm 60 relative to the underside 28A of the sole-supporting 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-supporting plate 28, making it possible to reliably support the sole-supporting plate 28.

[0077] In addition, in this embodiment, a bracket 62 is provided to fix the arm 60 in contact with the inclined surface 46A of the inclined member 46. This bracket 62 makes it possible to temporarily fix the arm 60 in a state in which the arm 60 is in contact with the inclined surface 46A of the inclined member 46, for example, by means of sliding resistance between the bolt 52 and the side wall of the through hole 50.

[0078] Therefore, the arm 60 can be temporarily fixed when adjusting the inclination angle of the sole-resting plate 28. Once the inclination angle of the sole-resting plate 28 is set, the bolt 52 is tightened against the nut 70 to fix the arm 60.

[0079] In this embodiment, a fixed wall 40 is disposed on the outer side of the support piece 34 along the width direction of the sole-placing 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-placing plate 28.

[0080] That is, the first fastening holes 36A formed in the support piece 34 among the plurality of second fastening holes 42 formed in the fixed wall 40 are aligned in accordance with the rotation angle of the sole-resting plate 28. Then, with the first fastening holes 36A aligned with the second fastening holes 42, 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-resting plate 28 at a predetermined inclination angle.

[0081] 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 placement plate 28.

[0082] The third fastening holes 36 formed in the support piece 34 among the plurality of fourth fastening holes 44 formed in the fixed wall 40 are aligned in accordance with the rotation angle of the sole-placing plate 28. Then, with the third fastening holes 36 aligned with the fourth fastening holes 44, bolts 38 are inserted into the third fastening holes 36 and the fourth fastening holes 44, and the support piece 34 and the fixed wall 40 are fastened together via the bolts 38 and nuts 39. This fixes the sole-placing plate 28 at a predetermined inclination angle.

[0083] 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 a pitch between the multiple second fastening holes 42, can be set even smaller.

[0084] As described above, in this embodiment, the inclination angle of the foot sole rest plate 28 can be easily adjusted, and by setting the inclination angle of the foot sole rest plate 28 to a small value, it can be used for testing vehicle seats of various types of vehicles.

[0085] That is, according to this embodiment, it is not necessary to prepare a footrest device 10 for each vehicle type. In other words, it is possible to test vehicle seats of various vehicle types with one 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.

[0086] 5, the present embodiment is provided with slide members 76, 78 that move the heel resting plate 74 toward and away from the sole resting plate 28. As a result, when adjusting the inclination angle of the sole resting plate 28, the slide members 76, 78 allow the heel resting plate 74 to move toward and away from the sole resting plate 28.

[0087] That is, 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 gap between the heel resting plate 74 and the sole resting plate 28. However, this is not limiting, as it is only necessary to be able to move the heel resting plate 74 towards or away from the sole resting plate 28.

[0088] In addition, the present invention can be implemented with various modifications within the scope of the gist thereof. Furthermore, it goes without saying that the scope of the rights of the present invention is not limited to the above-described embodiment. [Explanation of symbols]
