BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a cross section of a mounting area of a vehicle to which a footrest device 2 according to one embodiment is mounted. The footrest device 2 is disposed in front of the passenger compartment in a state where the footrest device 2 is entirely covered with a floor carpet 4, and is used for an occupant to put his / her feet 6.
[0013]
Reference numeral 8 in FIG. 1 indicates a steel dash panel that partitions a vehicle compartment and an engine room. The lower end of the dash panel 8 is integrally connected to a floor panel 10 extending in the horizontal direction.
At the lower part in the vehicle interior, a plate-shaped bracket 12 as a mounting wall is arranged obliquely from the dash panel 8 to the floor panel 10. The bracket 12 has both ends 14, 16 superimposed on the dash panel 8 and the floor panel 10, respectively, and is fixed to the dash panel 8 and the floor panel 10 via bolts. The bracket 12 has a fixing surface 18 that is recessed toward the engine room between both ends 14 and 16, and the fixing surface 18 extends obliquely with respect to the floor panel 10. The upper and lower ends of the fixing surface 18 are connected to the upper surface 24 of the bracket 12 via the step surfaces 20 and 22. Due to the presence of the step surfaces 20 and 22, the fixing surface 18 is larger than the upper surface 24 of the bracket 12. One step lower on the room side. That is, the fixing surface 18 and the step surfaces 20 and 22 form the recesses 26 in the bracket 12.
[0014]
Note that the fixing surface 18 may be formed on one of the dash panel 8 and the floor panel 10 or directly over the panels 8 and 10 instead of being formed on the separate bracket 12. That is, the mounting wall may be the body panel itself including the dash panel 8 and the floor panel 10.
Two through holes 28 are formed in the fixing surface 18 in the longitudinal direction, that is, in the front-rear direction of the vehicle, and the footrest body 30 is disposed on the fixing surface 18.
[0015]
The footrest main body 30 has a substantially rectangular parallelepiped shape, and has a mounting surface 32 in contact with the fixing surface 18 and a support surface 34 positioned on the opposite side of the mounting surface 32. The footrest body 30 has a predetermined thickness defined between the mounting surface 32 and the support surface 34, and this thickness is sufficiently larger than the depth of the recess 26 described above. Accordingly, the support surface 34 is higher than the upper surface 24 of the bracket 12 toward the vehicle compartment. In other words, the footrest main body 30 is in a state where a part on the mounting surface 32 side is fitted into the recess 26 of the bracket.
[0016]
The footrest body 30 is made of an elastic material. Specifically, the elastic material is made of an elastomer such as natural rubber or synthetic rubber, or a foamed plastic such as PA (polyacetal) or PS (polystyrene). Can be.
Two projections 36, 36 are integrally formed on the mounting surface 32 of the footrest body 30. These protrusions 36, 36 are arranged in the longitudinal direction of the footrest main body 30 so as to match the arrangement of the through holes 28, 28 of the bracket 12 (see FIG. 2), and are inserted into the through holes 28, 28. Therefore, the footrest body 30 is fixed to the bracket 12 with the mounting surface 32 in contact with the fixing surface 18 of the bracket 12.
[0017]
The protrusion 36 may be any shape as long as it can be fitted into the through-hole 28, and may be, for example, a column having a diameter substantially equal to that of the through-hole. However, in the case of the present embodiment, the projection 36 has the shape shown in FIG. More specifically, the protrusion 36 has a tapered tip, that is, is formed as a truncated cone-shaped head 40, and the head 40 is attached to the footrest main body 30, that is, the mounting surface 32 through a small-diameter shaft 42. They are linked together.
[0018]
The large diameter end of the head 40 is larger than the hole diameter of the through hole 28, however, the outer diameter of the shaft portion 42 is smaller than the hole diameter of the through hole 28, and its length is substantially equal to the thickness of the bracket 12.
Further, a rod-shaped core member 46 is coaxially embedded in each protrusion 36, and the core member 46 extends in the axial direction from the inside of the head 40 of the protrusion 36 to the inside of the footrest body 30.
[0019]
The core member 46 only needs to be able to impart an appropriate shear strength to the projection 36, and is not limited by its shape or material. For example, the core member 46 may have an annular rib integrally on the outer peripheral surface thereof, and the material is preferably resin. Specifically, as the material of the core member 46, a resin having excellent shear strength such as an ABS (acrylonitrile-butadiene-styrene) resin is preferable.
[0020]
The head 40 of the above-mentioned projection 36 is capable of penetrating through the through hole 28 of the bracket 12 with its elastic deformation, and the bracket 40 is provided between the head 40 and the mounting surface 32 of the footrest body 30 as shown in FIG. 12, and the shaft 42 is positioned in the through-hole 28.
Accordingly, the head 40 of the projection 36 prevents the projection 36 from coming out of the through hole 28, and the shaft 42 of the projection 36 regulates the front-rear and left-right movement of the footrest body 30 on the fixing surface 18. . As a result, the footrest main body 30 is stably fixed on the fixing surface 18.
[0021]
The head 40 of the projection 36 has a truncated cone shape, that is, a tapered shape toward the tip thereof, and the head 40 itself can be elastically deformed. The head 40 can easily penetrate the through hole 28 despite having a larger diameter than that.
When the footrest main body 30 is fixed to the fixing surface 18 of the bracket 12 as described above, thereafter, the footrest main body 30 is covered with the floor carpet 4, and the mounting of the footrest device 2 to the vehicle is completed.
[0022]
During operation of the vehicle, the occupant can place his feet 6 on the support surface 34 of the footrest body 30 via the floor carpet 4. Since the footrest body 30 is made of an elastic material as described above, the footrest body 30 prevents vibrations from the dash panel 8 and the floor panel 10 from being directly transmitted to the occupant's feet 6.
The shape of the footrest main body 30 is not limited to a substantially rectangular parallelepiped, and may be any shape as long as the foot 6 can be easily placed thereon and has excellent vibration absorption.
[0023]
Furthermore, since the footrest body 30 is made of the above-described elastic material, if the vehicle collides from the front, the footrest body 30 is compressed and deformed between the foot 6 and the fixing surface 18 of the bracket 12, and It absorbs the applied shock sufficiently and reduces the load on the ankle.
At this time, since the core member 46 is also made of resin, even if the core member 46 protrudes from the support surface 34 of the footrest main body 30 in the event of a frontal collision, the injury of the foot 6 by the core member 46 can be reduced. .
[0024]
According to the footrest device 2 having the above-described configuration, when the footrest body 30 is fixed to the bracket 12, it is not necessary to erect a screw stud on the fixing surface 18 by means such as welding. In addition, since the projection 36 is formed integrally with the mounting surface 32 of the footrest main body 30, it is not necessary to prepare a stopping member such as a clip separate from the footrest main body 30. Therefore, the configuration of the footrest device 2 is simplified, the footrest device 2 can be provided at low cost, and the footrest body 30 can be easily attached to the fixing surface 18.
[0025]
The step surfaces 20 and 22 above and below the fixing surface 18 can regulate the movement of the footrest body 30 in the front-rear direction. That is, the movement of the footrest body 30 in the front-rear direction is restricted not only by the protrusion 36 but also by the step surfaces 20 and 22. Therefore, even if the protrusion 36 is broken at the time of a frontal collision of the vehicle, the movement of the footrest body 30 in the front-rear direction is reliably restricted by the step surfaces 20 and 22, and the footrest body 30 continues to support the occupant's foot 6 reliably. Therefore, the impact on the foot 6 can be sufficiently absorbed.
[0026]
In addition, the footrest main body 30 with the protrusion 36 described above can be easily manufactured by a normal manufacturing method. For example, after the footrest main body 30 and the half of the projection 36 are integrally formed and foamed, the core member 46 is arranged at a predetermined position between the half bodies, and then these half bodies are press-bonded or adhered, so that the projection 36 is provided. Can be manufactured. Then, the obtained footrest body 30 with the protrusion 36 may be attached to the fixing surface 18 of the bracket 12 as shown in FIGS.
[0027]
The present invention is not limited to the embodiment described above, and various modifications are possible. For example, the footrest device 2 may be exposed without being covered by the floor carpet 4, or the footrest device 2 may be exposed. 4 may be covered with other sheet materials.
In the embodiment described above, the bracket 12 preferably has the step surfaces 20 and 22, but the bracket 12 does not necessarily have to have the step surfaces 20 and 22.
[0028]
In the above-described embodiment, the footrest main body 30 includes the two protrusions 36, 36, but the number of the protrusions 36 is arbitrary. However, the rotation of the footrest main body 30 with respect to the fixing surface 18 is easily prevented with two or more projections 36, 36.
[0029]
【The invention's effect】
As described above, according to the footrest device of the first aspect, it is possible to provide an easy-to-install and inexpensive footrest device by reducing the number of components and simplifying the manufacturing process.
According to the footrest device of the second aspect, the recess provided in the mounting wall prevents displacement of the footrest main body from the mounting wall in the event of a vehicle collision, so that the impact on the foot can be reliably absorbed. Therefore, the safety of the occupant can be further improved.
[0030]
According to the footrest device of the third aspect, since the projection has a tapered head, the head of the projection can be easily inserted into the through hole, and the head once passed through the through hole. Thereafter, since the mounting wall is sandwiched between the head and the footless main body, the footrest main body is prevented from being pulled out, and the footless main body is securely fixed to the mounting wall. According to the footrest device of the fourth aspect, since the core member is made of resin, the safety for the occupant can be further improved.
