Abstract

PURPOSE:To enable the use of a step without full opening a door by providing an interlocking device for fully projecting the step before the full opening of the door and another device for releasing an interlock between the door and the step when the step has been fully projected. CONSTITUTION:An interlocking device 30 has a link mechanism 32 and enables a step 10 to slide for full retraction and projection by turning a door 20 for the full closing and half opening thereof. When the step 10 has been fully projected, interlocking between the door 20 and the step 10 is released by an interlock releasing mechanism 40. And when said mechanism 40 is working, the retraction of the step 10 is regulated by a step stopper 50, thereby enabling the use of the step 10 without full opening the door 20 and also in a stable condition without any large space before the door 20.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a step for getting on and off a vehicle, and particularly to a step that is moved in and out in conjunction with opening and closing of a door.

(Prior art) As a conventional vehicle step, for example, Utility Model Application No. 58-2
The one described in Publication No. 172 is known.

This vehicle step is provided with a step that also serves as a bumper side protector on the vehicle body so that it can be moved in and out by rotation, and the step becomes retractable when the door is fully closed.
It was linked to the opening and closing of the door by an interlocking mechanism so that it was fully extended when the door was fully open.

(Problems to be Solved by the Invention) However, this conventional vehicle step has the following problems because the step fails to operate in conjunction with the opening and closing of the door between the fully closed state and the fully open state.

(b) If the door is not fully opened, the step will not be fully extended.1 For example, if there is no space in front of the door and the door cannot be opened wide, the step cannot be used.

(b) Because the door and step are always linked,
For example, if a door is closed while a person is on the step, the step will move back and forth, making the footing unstable (especially near the fully open door where the person's body on the step cannot prevent the door from closing). .

Conversely, for example, if someone gets on the step that is in the early exit state, the door will open, and if force is applied to the step on the exit side, the door will close, causing the door to open and close unexpectedly. be.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned conventional problems, and in order to achieve this purpose, the vehicle step of the present invention has the following features: A step for a vehicle is provided with a step that can be opened and closed, and an interlocking mechanism that moves the step in and out in conjunction with opening and closing of the door is provided between the door and the step, the interlocking mechanism comprising: An interlocking mechanism is provided in which the step is in a full-open state before the door is fully open, and the interlocking mechanism is provided with an interlock release mechanism that releases the interlock between the door and the step when the step is in the full-open state, and the interlock release mechanism is operated. Sometimes, a step stopper is provided to restrict the retraction of the step.

(Function) Therefore, in the vehicle step of the present invention, because of the above-mentioned means, the step is fully extended before the door is fully opened, so the step can be used without fully opening the door. can.

Further, in a state where the door is opened more than when the step is in the full state, the door and the step are not interlocked due to the operation of the interlock release mechanism.

Further, when the step is fully extended, even if a force is applied to the retracting side of the step, the step stopper does not cause the step to retract.

In addition, both slide levers 323 and 325 are the drive lever 3.
The rotation of 21 is transmitted to the first slide lever 323 via the first link 322, so that it is rotated in conjunction with the first slide lever 323.

Further, the first slide lever 323 is provided with a spring 328 that biases the slide step 10 to rotate in the direction of protruding and sliding.
One end of 28 is attached to a spring bracket 16 provided on the step mounting member 11.12.

The interlock release mechanism 40 is provided in the interlock mechanism 30 and releases the interlock between the door 20 and the slide step 10 when the slide step IO is fully extended. It consists of a striker 41 provided on the stay case 312 and a hook 42 provided on the door stay mounting bracket 315.

The hook 42 and the striker 41 are shown in FIGS.
As shown in the figure, the door 20 is in an engaged state between the fully closed position 20a and the half-open position 20b, and the door 20 is in the half-open position @
The mesh is disengaged between the fully open position 20b and the fully open position 20C.

Therefore, when the door 20 is in the range from the fully closed position to the half open position, the door stay 31 is pulled by the hook 42 as the door 20 is opened and closed, and the stay lever 311 connected to one end of the stay case 312 is moved around the drive shaft 33. However, in the range from the half-open position to the fully open position of the door 20, the stay rod 313 advances and the stay case 3
The position of one end of the stay lever 311 remains unchanged, and the stay lever 311 is not rotated.

The hook 42 is urged to rotate in the engaging direction by a spring (not shown), and the stopper portion 4 of the hook 42
Rotation due to the bias of the spring is regulated depending on whether the door 21 is brought into contact with the door 20 or completely engaged with the striker 41.

The step stopper 50 restricts the slide step lO from moving in and out when the door 20 and the slide step lO are not in an interlocked state due to the operation of the interlock release mechanism 40. provided, a stopper surface 51 is formed, and the interlocking mechanism 3
The stopper surface 51 is arranged so as to come into contact with the tip of the case projecting piece 314 of the door stay 31 when the door stay 31 is in the non-interlocking state.

Next, the operation of the embodiment will be explained.

First, a case will be described in which the door 20 is rotated from the fully closed position to the fully open position.

When the door 20 is opened and rotated, the stay case 312 is pulled toward the door 20 by the engagement between the hook 42 and the striker 41, and the stabilizer lever 311 of the stay case 312 is pulled toward the door 20.
The side end portion is rotated around the drive axis 33, and the stay lever 311 and the drive axis 33 are also rotated together with it.

As the drive shaft 33 rotates, the drive lever 321 of the link mechanism 32 is rotated and the first link 322 is pulled.
The first slide lever 323 is rotated in the direction of protruding and sliding the slide step IO, and the second slide lever 325 is also interlocked by the second link 324.

Above 1. As the second slide levers 323 and 325 rotate, the slide step IO is projected outward of the vehicle body 100.

Thereafter, this slide step 10 is fully extended at the half-open position M20b of the door 20 shown in FIG. 2.3, and when the door 20 is rotated to the half-open position, the angle of the stay case 312 relative to the door 20 changes As a result, the hook 42 and the striker 41 are disengaged, the interlocking movement between the door 20 and the slide step 10 is released, and the case protrusion 314 provided at one end of the stay case 312 touches the stopper surface 51 of the step stopper 50. The link mechanism 32 becomes in a locked state and the slide step l
O is restricted from entering or exiting.

As described above, the door 20 is opened at the half-open position 2 shown in FIG.
Between the fully open position 0b and the fully open position 20c, the interlock between the door 20 and the slide step 10 is released, and even if the door 20 is opened or closed, the slide step 10 remains fully extended and is restricted from moving in or out.

Next, door 20 to all the ministers! The case of closing from 20C to the fully closed position 20a will be described.

When the door 20 is rotated to close from all cabinets @ 20 c, the door stay 31 touches the case protrusion 341 of the stay case 312.
Since the stay lever 313 is in contact with the stopper surface 51 of the step stopper 50, the stay lever 311 and the stay case 31 are moved back and forth into the stay case 312.
It is rotated around the pivot point with 2.

Furthermore, from the fully open position 20c to the half-open position 20b of the door, the case protrusion 314 of the stay case 312 is in contact with the step stopper 50, so the drive lever 321 does not rotate, so the link mechanism 32 does not operate and the step lO
continues to remain fixed.

And door 20 is half open! When it is closed to t20b, the hook 42 is engaged with the striker 41, the door 20 and the slide step 10 are interlocked, and the case 312 is closed. The protruding piece 314 separates from the stopper surface 51, the link mechanism 32 becomes movable, and the restriction on the retraction of the slide step IO is released.

Thereafter, when the door 20 is closed, the slide step IO is also moved in and out by the interlocking mechanism 30, and the door 20
is in the fully closed position 20a, and the slide step IO is in the fully closed position.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, the step may be moved in and out by a rotation limited to a slide.

Further, in the embodiment, a door that opens and closes by rotating is used, but a door that opens and closes by sliding may also be used.

(Effects of the Invention) As described above, according to the vehicle step of the present invention, the interlocking mechanism is such that the step is fully extended before the door is fully opened, so that the door does not fully open. Since the step can be used even if there is no space in front of the door to fully open the door, the step can be used even if there is no space in front of the door to fully open the door, resulting in an effect that the door is easier to use.

In addition, by providing an interlocking mechanism in the interlocking mechanism that releases the interlocking between the door and the step when the stay 2 step is fully extended, the door opens more than when the step is fully extended. In this state, the door and step are not interlocked due to the operation of the interlock release mechanism, so that the step does not become unstable even if the door is opened or closed in this state.

In addition, by providing a step stopper that restricts the retraction of the stopper when the interlock release mechanism is activated, when the step is fully extended, the step will not be retracted even if force is applied to the retraction side of the step; .

The effect is that the door does not close unexpectedly.
