Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a retractable step for a vehicle or the like, and more particularly to a retractable step for a vehicle or the like that can be retracted and set by operating a lever in the vehicle. Is.

[Conventional technology]

As a conventional technique of a step attached to an entrance / exit of a vehicle, there is an emergency auxiliary step device disclosed in Japanese Utility Model Laid-Open No. 63-59761. Further, when there is a large step from the ground to the floor of the vehicle, there are steps that are fixed to the vehicle body inside or outside the vehicle, a movable folding type, and a retractable type.

[Problems to be solved by the device]

However, the fixed type has a drawback that the lowermost stage cannot be lowered so much as to prevent interference with the ground, and the movable type has a drawback that the structure is complicated and the stability is not stable.

In addition, when folding and setting (drawing), the setting work must be performed from outside the vehicle, which requires time to set and store, and the lower end of the step is arranged far away from the ground.

Then, this invention aims at provision of the retractable step of a vehicle etc. which was devised in view of the said fault.

[Means for Solving the Problems]

In order to achieve the above object, a retractable step of a vehicle or the like of the present invention is installed on a floor of an indoor floor where a door of a vehicle is attached, at a doorway, and a base having convex portions at both ends, and a rear portion of the base. The rear end is rotatably attached to the end convex portion so that it can be pulled up, and the operation lever is provided with a projecting piece having a long hole at the front end, and one end of the head serving as a rotation fulcrum is attached to the base. A connecting arm that is pivotally attached to the front end convex portion, the other end of the head is slidably attached to the elongated hole of the projecting piece, and the lower end of the head is provided with a hanging portion bent backward at a predetermined angle to the lower end portion. And the lower part of the indoor floor, which is substantially perpendicular to the indoor floor, and the rear part which is substantially parallel to this, the upper part which is substantially parallel to the floor part and the lower part which is substantially parallel to it, and the front part. It is composed of an inclined part that connects one end of the lower part, a triangular part is provided in the connecting part of the rear part and the lower part, and And a storage frame provided with a horizontal frame substantially parallel to each other, and the base is rotatably attached to the triangular portion, and a long hole is provided at the tip of one arm, and the lower end of the connecting arm is provided in the long hole. An L-shaped arm that is slidably attached to the shaft, a stopper that is disposed on the other arm of the L-shaped arm and that restricts rotation by engaging with an inclined portion of the storage frame, and one end of the L-shaped arm. A coupling link pivotally attached to the tip of the other arm of the pair of arms and a mounting portion provided on the rear surface of the upper ends of a pair of frames in which step plates of several stages are interposed are rotatably mounted on the horizontal frame of the storage frame. And a step of axially attaching to the other end of the coupling link at an intermediate position.

[Operation] When the tip end portion of the operation lever is pressed and rotated, the interlocking arm rotates, and the L-shaped arm interlocking with each other, the coupling link, and the step interlocking with the coupling link also rotate, and the step is stored. It is stored in the frame.

On the other hand, as the operating lever is pulled up, the tip of the connecting arm moves forward in the horizontal direction, and the L-shaped arm rotates about the shaft as a fulcrum, and at the same time, the coupling link rotates and extends in the vehicle side direction to step. Is set outside the car.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The operation part is composed of a base 41 and an operation lever 4. The base 41 is attached to the indoor floor 7 at the entrance / exit position where the vehicle door 10 is attached, and a convex portion 42 is provided at the front end and at the rear end. A rear end convex portion 43 having the same height as the convex portion 42 is provided.

A rear end of the operation lever 4 is rotatably attached to the rear end convex portion 43, and a projecting piece 44 provided with an elongated hole 45 is provided at the tip of the operation lever 4. The storage frame 6 has a front portion 61 and a rear portion 65 which are parallel to the floor portion 7 at right angles to the floor portion 7, an upper portion 66 which is parallel to the floor portion 7 and a lower portion 67 which is parallel to the front portion 61, and one end of the front portion 61 and the lower portion 67. It is composed of connected inclined portions 63.

The connecting arm 5 constituting the movable mechanism has one end of the head portion 51 pivotally attached to the convex portion 42 serving as a rotation fulcrum, and the other end slidably attached to the elongated hole 45 of the projecting piece 44. There is. Also, the head 51
A hanging portion 52 is provided at the lower end, and a lower end portion 53 of the hanging portion 52 is bent backward at an angle of about 45 °.

Further, the L-shaped arm 2 has a base portion 23 rotatably attached to a triangular portion 64 provided on the rear side of the storage frame 6 while a long hole 24 is provided at the tip of the arm 21. The lower end of the connecting arm 5 is slidably attached to the shaft.

One end of the coupling link 3 is pivotally attached to the tip of the other arm 22 of the L-shaped arm 2 and the other end of the coupling link 3 is pivotally attached to an intermediate position of the vertical frame 15 of step 1.

At this time, since the axial point C is located below the straight line connecting the axial points b and d, the inclined portion provided below the front side of the storage frame 6
The L-shaped arm 2 is provided with a stopper 9 which is stopped by 63 and regulates rotation.
The other arm 22 is disposed.

Further, in the step 1, at the time of setting, the lower end of the vertical frame 15 is extended so as to be close to the ground, and a plurality of step plates 11, 12, 13 are provided between the pair of vertical frames 15, and A mounting plate 14 is provided on the rear surface of the upper end of the vertical frame 15, and the mounting plate 14 is mounted on a horizontal frame 62 parallel to the storage frame 6 so that the upper end of the step 1 is located outside the vehicle side surface 8. I am doing it.

[Effect of device]

According to the present invention having the above-described structure, the movable mechanism is provided and the structure is relatively simple. When setting, the lower end of the step can be arranged near the ground even if the floor is very high, and the storage is easy. .

Further, since the operation unit is provided inside the vehicle and can be stored and set from the inside of the vehicle by operating the operation unit, the operation unit can be operated even under adverse conditions such as rain outside.

Further, since the movement is restricted below the straight line connecting the axial point C to the axial points b and d, the L-shaped arm does not rotate even if a load is applied to the step, and the step can be maintained in a stable state. .
