  In the above-mentioned auxiliary step, since it is stored in the passenger compartment when not in use, it can be protected from the outside environment such as rainwater, mud splash, etc., but the stored state is the inverted state of the auxiliary step via the hinge on the standing arm. Therefore, the auxiliary step blocks the entrance of the vehicle in such a stowed state, so that the auxiliary step must be developed even when an occupant who does not need the auxiliary step gets on and off, for example.

  In the use state of the above-mentioned auxiliary step, an extended two-folded link is obliquely bridged between the tip side of the arm part hanging down from the entrance and the auxiliary step horizontally arranged at the lower front part of the entrance and exit. Thus, the use state in which the auxiliary step extends horizontally from the arm is maintained. In such a use state, for example, when a passenger sits on a second-row seat in a minivan-type passenger car having a three-row seat. Is stepped on the auxiliary step toward the left side (front of the vehicle) of the entrance / exit, and when seated in the third row seat, stepped on the auxiliary step toward the right side (rear of the vehicle) of the entrance / exit. For this reason, there is a danger that the two-folded link will trip over, which has the same danger when getting off the vehicle.

Therefore, in the present invention, it is possible to freely get on and off even in the state of being stored in the vehicle interior, and without providing the stepping plate support mechanism such as the arm portion and the two-folded link on the left and right sides of the auxiliary step, at the time of getting on and off, But safe to passenger, as the three rows of seats car minivan or the like, aims to provide an optimal vehicle interior manual retractable auxiliary step left and right at entrance to vehicle passenger divided into (longitudinal direction of the vehicle) And

In view of the above problem, a manually retractable auxiliary step of the vehicle interior of the present invention is a tread plate provided so as to be reciprocally movable between a storage position on a vehicle step already provided in the vehicle interior and a projecting position at a lower front part of the vehicle step. a is, between the the tread plate and the vehicle step-side, step board is disposed horizontally retracted position and the projecting position, and, provided the treadle support mechanism for reciprocating the fixed orbit, the tread plate support The mechanism section vertically erects a post protruding a handle in the vicinity of a central portion behind the tread plate, and pivotally connects an arm that suspends the post at the overhang position between the post and the vehicle step side. And a bent portion of a bell crank pivotally connected to an appropriate position of the arm, and links are pivotally connected between one end of the bell crank and a support, and between the other end of the bell crank and a vehicle step side, respectively. It is characterized by the following.

In short, the auxiliary step according to the present invention includes a step board support mechanism that arranges the step board horizontally at the retracted position and the extended position in the vicinity of the center portion behind the step board, and reciprocates on a fixed track on the vehicle step side. In the extended state in which the auxiliary step is used, the tread plate support mechanism is located near the center of the rear of the tread plate instead of the left and right as in the conventional case. When the passenger gets on and off the vehicle at the entrance and exits at the right and left (in the front-rear direction of the vehicle), the driver can get on and off safely without any obstacles.
In addition, as described above, the tread plate can be reciprocated between the retracted position and the overhang position with a fixed trajectory, so that the tread plate does not swing during movement, and the operation posture is stable. When the vehicle is not in use, the treads are horizontally arranged on the vehicle steps as an alternative step, so that the treads do not obstruct the vehicle entrance and the treads are deployed (vehicles outside the vehicle). In the case where it is not necessary to protrude to the lower part in front of the step), it is possible to freely get on and off even in that state, and it is possible to maintain a stable storage state even while the vehicle is running, and it is safe.

Further, step board support mechanism includes an arm for suspending a post at the projecting position between the vertically erected posts projecting from the handle to the front near the center of the step board rear, the strut and the vehicle step-side Pivotly connect the pivots of the bellcrank in place on the arm and pivot the links between one end of the bellcrank and the strut and between the other end of the bellcrank and the vehicle step side, respectively. Since the connection is made, the posture of the tread plate can always be regulated, and especially the stabilization of the tread plate can be prevented while moving, and the tread plate can be easily moved in and out safely.
In the extended state, which is a use state of the auxiliary step, the arm hangs on the upright column, and the bell crank and the link connected to each end thereof support the vicinity of the center of the tread plate along the arm. Therefore, these tread plate support mechanisms (posts, arms, bell cranks, and links) do not obstruct at all when getting on and off, and have a great practical effect, such as being able to get on and off safely.
