DETAILED DESCRIPTION OF THE INVENTION
A preferred embodiment of the present invention will be described below with reference to FIGS. This embodiment relates to a right-hand drive vehicle. In the figure, A indicates the front side, B indicates the rear side, C indicates the right side, and D indicates the left side.
[0018]
Reference numeral 1 denotes a footrest, which is attached to an inclined dash lower panel 2. A portion corresponding to the footrest 1 of the dash lower panel 2 is an embossed portion 3 as a “vehicle body surface” raised upward, and a tunnel portion 4 is bulged and formed on the vehicle body center side of the dash lower panel 2. . An insulator 5 and a carpet 6 are laid on the surfaces of the dash lower panel 2 and the tunnel portion 4 except for the embossed portion 3.
[0019]
The footrest 1 has a substantially box shape having a footrest plate 7 on the upper part, and a left end 7d of the footrest 1 extends in a straight line and is in contact with a carpet 6 covering the tunnel portion 4 at the center of the vehicle body. The front end 7 a, the rear end 7 b, and the right end 7 c of the footrest 1 are also in contact with the carpet 6. The footrest plate 7 is formed with a lattice-like pattern shape in order to obtain an anti-slip effect and a decorative effect.
[0020]
In the embossed portion 3, stud bolts 9 having the same length are erected at two positions in the front and rear. Also, two front and rear cylindrical portions 10 are integrally formed from the footrest plate 7 of the footrest 1 toward each stud bolt 9. Although the cylindrical part 10 is formed in the relationship of the vertical position in the footrest plate 7, the upper side is formed longer than the lower side, since the structure is the same, including the clip 11 described later, in FIG. Detailed symbols for the upper structure are omitted.
[0021]
The cylindrical portion 10 is in a state of penetrating in the longitudinal direction of the stud bolt 9, and the lower end thereof is in contact with the embossed portion 3. In addition, a rib R formed on the lower surface of the footrest plate 7 is connected to the cylindrical portion 10. The inner diameter of the upper part of the cylindrical part 10 is formed larger than the lower part via the seat surface 12. Three fitting grooves 13 are formed on the seat surface 12 at equiangular three-way positions. The inner diameter of the lower portion is larger than the diameter of the stud bolt 9, and a predetermined gap is formed between the cylindrical portion 10 and the stud bolt 9.
[0022]
A second notch 14 having a width wider than the diameter of the stud bolt 9 and allowing the stud bolt 9 to pass through is formed on the rear side of the lower portion of the cylindrical portion 10 as “one direction”. Furthermore, a step portion 15 is formed at the lower end of the lower portion of the cylindrical portion 10 in the circumferential direction excluding the second notch portion 14.
[0023]
Clips 11 having corresponding lengths are inserted into the cylindrical portion 10. The clip 11 is formed of a head portion 16, a trunk portion 17, and a leg portion 18. Since the upper clip 11 is longer, the trunk portion 17 is also longer. The head portion 16 has a circular shape corresponding to the cylindrical portion 10, and the upper surface is inclined so as to be flush with the footrest plate 7, and the same pattern shape as the footrest plate 7 is formed. The body portion 17 has a cylindrical shape, and three fitting pieces 19 that can be fitted from the upper side are formed in the fitting groove 13 formed in the seating surface 12 in the radial direction. In this embodiment, the “rotation preventing means” is formed by the fitting groove 13 and the fitting piece 19.
[0024]
The leg portion 18 has a cylindrical shape that can be inserted into a gap between the stud bolt 9 and the lower portion of the cylindrical portion 10. An upward inner locking claw 20 that can be engaged with the thread groove of the stud bolt 9 is formed on the inner surface of the leg portion 18 (see FIG. 5). Further, on the outer surface of the lower end of the leg portion 18, an upward outer locking claw 21 that can engage with the step portion 15 formed on the inner surface of the cylindrical portion 10 is formed.
[0025]
A first cutout 22 having a width smaller than the diameter of the stud bolt 9 is formed on the rear side of the leg 18 as “one direction”. The second cutout portion 14 is formed wider than the first cutout portion 22, but the first cutout portion 22 is narrow in width and extends along the embossed portion 3 with a predetermined value or more with respect to the clip 11. Only when the lateral load F is applied, the stud bolt 9 is forcibly removed from the first notch 22.
[0026]
Next, how to attach the footrest 1 will be described. First, the footrest 1 is set on the embossed portion 3, and the cylindrical portion 10 is extrapolated to the stud bolt 9. The lower end of the cylindrical portion 10 extrapolated to the stud bolt 9 is in contact with the embossed portion 3.
[0027]
Next, the clip 11 is inserted into the cylindrical portion 10 from above. Since both the inner locking claw 20 and the outer locking claw 21 are in the upward state, smooth insertion is performed. At the same time when the clip 11 is inserted, the fitting pieces 19 are fitted into the fitting grooves 13 respectively. The insertion of the clip 11 is stopped when the head 16 comes into contact with the seat surface 12, the tip of the inner locking claw 20 is engaged with the thread groove of the stud bolt 9, and the outer locking claw 21 is engaged with the cylindrical portion 10. Engages with the step 15 on the inner surface. Accordingly, the cylindrical portion 10 of the footrest 1 is attached to the stud bolt 9 via the inner locking claw 20 and the outer locking claw 21 of the clip 11. In this way, the footrest 1 can be attached with a single touch of inserting the clip 11.
[0028]
Since the attached footrest 1 is in a state where the lower end of the cylindrical portion 10 is in contact with the embossed portion 3, the weight of the foot applied to the footrest plate 7 is firmly supported by the embossed portion 3 via the cylindrical portion 10. Can do. The width of the first notch 22 is narrower than the diameter of the stud bolt 9, and the stud bolt 9 does not come out of the first notch 22 under a load applied in a normal use state.
[0029]
Moreover, since the rigidity of the dash lower panel 2 in the peripheral part of the stud bolt 9 is increased by forming the embossed part 3, the mounting rigidity of the footrest 1 is also improved. Furthermore, since the same pattern shape as the footrest plate 7 is formed on the upper surface of the head 16 of the clip 11, the anti-slip effect and the decorative effect are high, and the rotation of the clip 11 is prevented. The pattern shape with the footrest plate 7 does not shift.
[0030]
Next, how to remove the footrest 1 will be described. When removing the footrest 1, a lateral load F larger than the load normally applied to the footrest 1 is applied in the front direction along the embossed portion 3. When a lateral load F of a predetermined value or more is applied to the footrest 1, the load F is also applied to the leg portion 18 of the clip 11 through the cylindrical portion 10, so that the stud bolt 9 is forced from the first notch portion 22 of the leg portion 18. The stud bolt 9 is pulled out from the cylindrical portion 10 through the second cutout portion 14 as it is.
[0031]
Thus, by applying a larger load F than usual to the footrest 1, the footrest 1 can be detached from the stud bolt with one touch. Moreover, since the lateral load F applied for removal is the front direction opposite to the direction in which the first notch 22 is formed, the load F can be easily applied from the driver's feet, and the removal work is easy.
[0032]
In the above embodiment, the “rotation preventing means” has been exemplified by the structure composed of the fitting groove 13 and the fitting piece 19, but is not limited thereto. For example, the upper portion of the cylindrical portion 10 and the clip 11 are used. The heads 16 may be formed in a non-circular shape (square, hexagon, etc.) that cannot rotate relative to each other.
[0033]
【The invention's effect】
According to the first aspect of the present invention, when a lateral load of a predetermined value or more is applied to the footrest, the load is also applied to the leg portion of the clip via the cylindrical portion, so that the stud bolt is removed from the first notch portion of the leg portion. The stud bolt is forcibly pulled out, and the stud bolt is also pulled out from the cylindrical portion through the second cutout. That is, the footrest can be removed from the stud bolt with a single touch by applying a larger load than usual to the footrest.
[0034]
According to the second aspect of the present invention, the fitting piece formed on the clip is fitted into the fitting groove formed on the seating surface of the cylindrical portion, and the rotation of the clip in the cylindrical portion is prevented.
[0035]
According to the invention described in claim 3, since the upper part of the cylindrical part and the head part of the clip are non-circular, the rotation of the clip in the cylindrical part is prevented.
[0036]
According to the fourth aspect of the invention, since one direction of the leg portion of the clip forming the first notch portion is the rear side direction of the vehicle, the lateral load applied for removal is the front side direction. Since the load in the front direction can be easily applied from the driver's foot, the removal work is facilitated.
[0037]
According to the invention described in claim 5, since the lower end of the cylindrical portion is in contact with the vehicle body surface, the weight of the foot applied to the footrest plate of the footrest can be firmly supported on the vehicle body surface via the cylindrical portion. .
[0038]
According to invention of Claim 6, since the same pattern shape as a footrest board is formed in the head upper surface of a clip, the anti-slip | skid effect and a decoration effect are high. Further, since the rotation of the clip is prevented, the pattern shape between the clip and the footrest plate does not shift.
