[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary step for improving the getting on and off of an automobile.

[0002]

2. Description of the Related Art FIG. 15 shows a conventional example in which an auxiliary step is provided at the entrance of a vehicle to facilitate the entry and exit of infants and the elderly. Reference numeral 1 denotes a cabin floor of an automobile, on which a main body getting on / off step 2 is formed. An auxiliary step 3 is slidably provided at the lower part of the vehicle body.
When not in use, it is stored as shown by the solid line in the figure,
As shown by the imaginary line, the vehicle advances outward from the side of the vehicle body and is used. Thus, from the road surface, the auxiliary step 3, the main body getting on and off step 2, and the cabin floor 1
A stepped step is configured so that even an infant or the like can easily get on and off.

[0003]

However, the step 2 for getting on and off the main body of the vehicle is fixedly formed, and the step between the cabin floor 1 and the step 2 for getting on and off the main body is fixed. On the other hand, in the conventional auxiliary step as described above, since the auxiliary step 3 needs to secure a considerable amount of clearance from the road surface at the time of storage, the height of the auxiliary step 3 can be increased even when it is advanced for use. There is a limit to lowering. As a result, it is difficult to evenly distribute the steps of the steps, and if the step h2 between the body main body getting on / off step 2 and the auxiliary step 3 is smaller than the step h1 between the cabin floor 1 and the main body getting on / off step 2, I had no choice.
Therefore, for a small infant or the like, a high step h1 between the main body getting on / off step 2 and the vehicle cabin floor 1 still remains, and there is a sense of incongruity because the step when getting on / off using the auxiliary step differs vertically.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an auxiliary step capable of reducing each step of a step without causing a sense of incongruity in use.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a slide rail that slides along a roller provided at a lower part of a vehicle body, a first step plate fixed to the slide rail, and an upper side of the first step plate. , A link member connecting an end of the first step plate on the vehicle body side and an outer end of the second step plate, and a vehicle body of the second step plate on the lower vehicle body wall of the passenger compartment floor. Means for fixing and holding a side end portion, wherein the slide rail is provided between a storage position for accommodating the first and second step plates, which are formed by folding the link and overlapping the first and second step plates, in a vehicle body and a pull-out position for projecting outside the vehicle body. The link member is pivoted in the pulled-out position to separate the second step plate upward from the first step plate, and the vehicle body side end of the second step plate is fixedly held by the second step plate. A second step plate and an auxiliary step is arranged with a step above the first step plate by fixing holding the lower body wall of the vehicle compartment floor.

[0006]

According to the above assisting step, first, the first and second step plates folded and overlapped from the stored state are slid out and pulled out and positioned outside the vehicle body outer surface.
Thereafter, the link member is raised together with the second step plate while raising the vehicle-side end of the second step plate to avoid interference with the vehicle outer surface. Then, the vehicle body side end of the second step plate is fixedly held to the vehicle body wall below the vehicle cabin floor.
