操作に違和感を与えるものであつた。(Problems to be Solved by the Invention) However, in the case of the above-described movable step, the holding of the step in the fully extended state, the opening / closing operation of the door, and the interlocking release of the step-in / out operation are independently and separately performed. For this reason, depending on the assembled state of the holding mechanism and the release mechanism, the holding in the fully extended state of the step, the opening / closing operation of the door and the release of the interlocking of the entering / exiting operation of the step are not performed simultaneously, and in the worst case, Even when the interlocking operation between the opening / closing operation and the in / out operation of the step is released, the step is not held in the full out state, and there is a possibility that the step may be in a free state. In order to prevent this, there is provided an urging means for constantly urging the step in the holding state direction (toward the full extension state), and when the holding operation is delayed with respect to the interlock release operation, the urging means is attached. The forces force the turrets to go all the way out. For this reason, the urging force of the urging means affects the door opening / closing force, and the door opening / closing force is interlocked when the step in / out operation and the door opening / closing operation are interlocked and when the step in / out operation and the door opening / closing operation are not interlocked. In contrast, the door operation was uncomfortable.

c is separated from the arcuate surface 15a of the link 15 and faces the fitting groove 15b. As a result, the second latch 19 receives the urging force of the spring 20, rotates in the fifth clockwise direction as shown by the two-dot chain line in the fifth drawing, and the fitting portion 19a fits into the fitting groove 15b, The rotation of the link 15 with respect to the second operation link 12 is restricted. As a result, the step 7 is in the holding state in the fully extended state. Due to the rotation of the second latch 19, the first latch 18 also rotates counterclockwise in the fifth illustration as shown by the two-dot chain line in the fifth illustration by the urging force of the spring 20, and the engagement between the claw portion 18a and the pin 16 is increased. Is canceled. As a result, the first operating link 11 and the second operating link
The integrated rotation with the door 12 is released, and the interlocking operation between the opening / closing operation of the door 3 and the entrance / exit operation of Step 7 is released. After this, door 3
Is rotated in the counterclockwise direction in the third illustration, only the door 3 is rotated, and the door 3 is fully opened as shown by the two-dot chain line in the third illustration.

ことができる。As described above, since the step 3 is held in the fully extended state shown by the solid line in the third illustration before the door 3 is fully opened as shown by the two-dot chain line in the third illustration, the door 3 in a narrow place or the like is fully opened. Even when getting on and off in a place where the state cannot be set, getting on and off using step 3 can be performed safely.
Further, the first latch 18 is rotated by the holding operation by the engagement between the fitting portion 19c and the fitting groove 15b by the rotation of the second latch 19, and the claw portion is rotated.
Since the engagement between the pin 16 and the pin 18a is released to release the interlocking operation between the opening / closing operation of the door 3 and the in / out operation of the step 7, the holding operation and the interlocking releasing operation are surely performed almost simultaneously. . As a result, the free state in which the step 7 is not interlocked with the door 3 and is not held is prevented, so that the self-movement of the step 7 can be prevented. Further, the holding operation and the interlock release operation can be performed almost simultaneously without providing an urging means such as a spring for urging the step 7 in the holding state direction.
The urging means becomes unnecessary, and the urging force of the urging means does not affect the opening / closing force of the door 3. As a result, the door 7 is moved in and out of the step 7 by the action of the urging force of the urging means.
The door operation at the time of interlocking with the opening / closing operation of the door and at the time of non-interlocking of the opening / closing operation of the step 7 and the opening / closing operation of the door 3 can be eliminated, and the door operation can be performed with a smooth feel.

閉状態となる。When the door 3 is rotated clockwise in the third illustration to change from the fully opened state shown by the two-dot chain line in the third illustration to the fully closed state shown by the solid line in the second illustration, the first operation link 11 is rotated via the link 13. .
When the first operating link is in the state shown by the solid line in FIG.
17 presses the first contact surface 19a of the second latch 19, and the second latch 19 turns counterclockwise in the fifth illustration against the urging force of the spring 20, as shown by the fifth solid line in the fifth illustration. The fitting between the fitting portion 19c and the fitting groove 15b is released. This results in link 1
5 becomes rotatable with respect to the second operating link 12, and the holding state of the step 7 is released. Due to the rotation of the second latch 19, the second contact surface 19a of the second latch 19 presses the contact portion 18b of the first latch 18 so that the first latch 18 also resists the urging force of the spring 20 as shown in FIG. The pin rotates in the clockwise direction and the claw portion 18a and the pin 16 are engaged with each other as shown by the fifth solid line in FIG. As a result, the first operation link 11 and the second operation link 12 rotate integrally, and the operation of entering and exiting the step 7 and the operation of opening and closing the door 3 are linked. Thereafter, by further rotating the door 3 clockwise in the third illustration, the arm 5 rotates counterclockwise in the third illustration, and the step 7 moves in the opposite direction to that described above, and the two-dot chain line in the second illustration Through this position, the door 3 is fully closed as shown by the solid line in FIG. 2 and the door 3 is also fully closed as shown by the solid line in FIG.

より先に行われるようにしてもかまわない。It should be noted that the holding operation in the full exit state, the opening / closing operation of the door 3 and the interlock release operation of the entrance / exit operation of the step 7 are performed almost simultaneously, but the holding operation in the full exit state is performed earlier than the interlock release operation. You can do it.
