Embodiments of the present invention will be described below.

FIG. 1 is a perspective view showing an automobile side step according to a first embodiment of the present invention. FIG. 2 is A- of FIG.
FIG. 3 is a sectional view taken along line A.

In the figure, the same reference numerals and symbols as those of the conventional example indicate the same or corresponding parts as those of the conventional example, and therefore, a duplicate description will be omitted here.

As shown in FIGS. 1 and 2, the automobile side step of this embodiment is formed by sandwich molding.
The hard resin material 2 is provided inside the base 21 made of a soft resin material.
3, the outer shape of the base portion 21 is a long shape fixed along the lower edge of the door opening. In addition, the base portion 21 has a substantially flat plate-like step portion 21a that extends outward in a substantially horizontal direction from the lower edge of the door opening, and projects upward to the upper end on the inner side (left side in FIG. 1) in the width direction of the step portion 21a. The first shielding portion 21b is integrally formed, and the second shielding portion 21c that hangs downward is integrally formed at the lower end on the inner side in the width direction. In addition, on the upper surface of the step portion 21a, an uneven slip prevention portion 21d for preventing slip when an occupant places his / her foot is extended in the length direction. On the other hand, the hard resin material has a substantially L-shaped cross section corresponding to the cross-sectional shapes of the step portion 21a of the base portion 21 and the second shield portion 21c, and constitutes the rigidity increasing means of the present embodiment. The hard resin material 23 is extended over substantially the entire length of the base portion 21. The rigidity increasing means increases the cross-sectional area or outer dimension of the base portion 21 by that amount to increase the strength and rigidity of the base portion 21 itself, and at the same time, the rigidity of the hard resin material 23 itself as the rigidity increasing means allows the base portion 21 to be increased. The rigidity of the whole is also increasing.

Further, the lengthwise front end of the base 21 is
An inclined surface 21e is formed by bending upward from the upper surface of the slip prevention portion 21d, and a front end thereof is continuous with a rear end of a front wheel house (not shown) and a mudguard (not shown) is attached. A mudguard mounting portion 25 having a substantially flat plate shape is formed integrally. The mudguard mounting portion 25 is integrally formed of the same soft resin material as the base portion 21 so as to be substantially orthogonal to the base portion 21 during the sandwich molding. A known mudguard is attached to the mudguard attachment portion 25 via a fastener (not shown) such as a screw.

Here, as the soft resin material of the base portion 21, thermoplastic rubber (TPR) is used, but as long as chipping resistance and scratch resistance are good, soft polyvinyl chloride (PVC) resin is used. , Ethylene vinyl acetate (EVA) resin, polypropylene with rubber dispersed (P
Other soft resin materials such as P) resin and thermoplastic elastomer (TPE) may be used.

Further, as the hard resin material 23 of the rigidity increasing means, polypropylene (PP) resin mixed with a filler or a reinforcing material such as talc or glass fiber is used.
As long as the rigidity of the base is increased to withstand the occupant load, acrylonitrile butadiene styrene (AB
Other rigid resin materials such as S) resin, rigid polyvinyl chloride (PVC) resin may be used.

In order to manufacture the automobile side step of the present embodiment configured as described above, the hard resin material 23 is injected and filled into the soft resin material by a known sandwich molding technique, and then, as shown in FIG. As shown, a rigidity increasing means made of a hard resin material 23 is integrally molded in a base portion 21 made of a soft resin material, and a mudguard mounting portion 25 is integrally molded at the front end of the base portion 21.

At this time, the hard resin material 23 as the rigidity increasing means is not limited to the step portion 21a and the second shield portion 21c of the base portion 21 but also the first shield portion 21b.
Alternatively, the rigidity of the base portion 21 may be further increased by filling the same with a cross-sectional shape substantially similar to the overall cross-sectional shape of the base portion 21. Further, the mudguard attachment portion 25 may be filled with the hard resin material 23 to increase its rigidity, or may be filled with the hard resin material 23 and maintain the flexibility of the soft resin material. Good. When the flexibility of the soft resin material is maintained without being filled with the hard resin material 23, the mudguard mounting portion 25 itself becomes elastically deformable together with the mudguard, thereby improving its functionality and design.

The automobile side step of the present embodiment having the above-described structure is similar to the conventional example in that a rocker as a body side mounting portion is attached via a stay 101 with a fastener (not shown) such as a bolt. It can be attached to a panel (not shown). When the vehicle side step is mounted on the body, an occupant places his / her foot on the step portion 21a of the base portion 21 to facilitate getting in / out of the vehicle. At this time, the base portion 21 is made of resin and has a rigidity lower than that of the conventional aluminum side step 111 made of aluminum, but the rigidity is increased by the hard resin material 23 as a rigidity increasing means, so that the base portion 21 is deformed and damaged. There is no problem such as ripping.

As described above, the automobile side step according to the above-described embodiment has an elongated shape fixed along the lower edge of the door opening, and extends substantially horizontally outward from the lower edge of the door opening. A base 21 made of a soft resin material having a flat step portion 21a, and a hard resin which is integrally molded into the base 21 in a predetermined cross-sectional shape by sandwich molding to increase the cross-sectional area of the base 21 and increase the rigidity. A rigidity increasing means made of a material 23, and a mudguard mounting portion 25 which is integrally formed at the front end of the base portion 21 in the longitudinal direction, is continuous with the rear end of the front wheel house, and has a substantially flat plate shape capable of mounting a mudguard. It is equipped with.

Therefore, in the above embodiment, since the entire side step for automobiles can be formed of the resin material, it is easy to process, and its shape can be easily made into various and complicated shapes. . For example, as in the illustrated example, the base 21 has an uneven slip prevention portion 2
It is possible to integrally form a desired three-dimensional shape having a different shape, such as 1d, the inclined portion 21e, and the mudguard mounting portion 25. Also,
The resin side step for automobiles can be sufficiently lightened as compared with the conventional example made of an aluminum material, and further, the weight reduction can reduce the labor at the time of mounting work. Here, when the entire side step for an automobile is simply made into a resin, its rigidity is reduced as compared with the conventional example made of an aluminum material. Further, if the overall thickness is increased to ensure the rigidity, problems such as sink marks may occur. However, in this embodiment, since the hard resin material 23 as the rigidity increasing means is filled in the base portion 21 by sandwich molding, the outer shape of the base portion 21 itself is enlarged to increase the rigidity thereof, and at the same time, the rigidity increasing means. With this, the base portion 21 can be supported to further increase the overall rigidity, and even if compared with the conventional example, the problem of insufficient rigidity does not occur. Moreover, since the thickness of the base portion 21 itself is small, problems such as sink marks do not occur.

Further, in this embodiment, since the base portion 21 is made of the soft resin material, the chipping resistance or the scratch resistance is good, and the design surface is damaged by the pebbles scattered from the road surface during traveling, and the passenger's Step part 21a when getting on and off
It is possible to prevent the upper surface and the like from being scratched. in addition,
When assembled to the body, the first and second shielding portions 21b,
By 21c, the body-side mounting portion can be shielded from the outside, and the overall appearance can be improved.

Next, another embodiment according to the present invention will be described below. In each embodiment, only the differences from the first embodiment will be described, and the same components as those in the first embodiment will be designated by the same reference numerals in the drawings and the description thereof will be omitted.

It may also be formed in 1b to have a cross-sectional shape that is substantially similar to the overall cross-sectional shape of the base 31 to further increase the rigidity of the base 31.
Further, regarding the mudguard mounting portion, a hollow portion 33 may be formed to increase the rigidity thereof, or the hollow portion 33 may be formed.
It may be thin without forming. In particular, since the portion of the base 31 where the hollow portion 33 is provided has a great effect of preventing sink marks,
In consideration of the thickness of the portion and the like, it is preferable to select the location where the hollow portion 33 is provided from the viewpoint of rigidity and sink prevention.

The automobile side step of the present embodiment configured as described above can be assembled to the body side mounting portion in the same manner as the first embodiment, and after the assembly, the first embodiment is performed. As well as, it makes it easy for passengers to get in and out of the vehicle.
Further, the base portion 31 is made of resin and has a rigidity smaller than that of the conventional aluminum side steps for automobiles, but the rigidity is increased by the hollow portion 33 as a rigidity increasing means, so that the base portion 31 is deformed and damaged. There is no defect.

As described above, in the automobile side step of the second embodiment, the base 31 is made of a hard resin material,
A hollow portion 33 is formed in the base portion 31 as a means for increasing rigidity by gas injection molding.

Therefore, the above-described embodiment has the same operation and effect as the first embodiment, and in addition, the base 31
Since it is made of a hard resin material, it does not have chipping resistance, but it is a hard resin material 2 as a means for increasing the rigidity.
3 can be replaced by the hollow portion 33, and the weight can be further reduced by that amount. Further, the weight reduction can further reduce the labor at the time of mounting work. In this embodiment, since the hollow portion 33 as the rigidity increasing means is formed in the base portion 31 by gas injection molding, the outer shape of the base portion 31 itself can be enlarged to increase the rigidity. In particular, in the present embodiment, since the base portion 31 itself made of a hard resin material has considerable rigidity, even if compared with the conventional example,
The problem of insufficient rigidity does not occur. Further, since the thickness of the base portion 31 itself is small, problems such as sink marks do not occur.
