So set up, footboard 20 arranges in proper order along the horizontal direction and by the bottom of elevator car arrange the layout mode to the top in proper order can form step structure to act as the stair and supply the user to walk, the user need not both hands and assist the climbing, only relies on both legs can use, has liberated user's both hands, makes things convenient for its handheld other tools. And the pedal 20 can rotate around one end connected with the mounting plate 10, so the pedal 20 can be flexibly switched between a folded state and a working state, and the pedal 20 can be rotated and folded when not in use, thereby reducing occupied space.

Preferably, the plurality of pedals 20 are arranged in a step-like manner, and each pedal 20 is rotatable in a vertical direction relative to the mounting plate 10 to a position parallel to the mounting plate 10 and against the mounting plate 10. The pedal 20 can rotate in the vertical direction by means of gravity, so that the rotation is more labor-saving and convenient. Of course, in other embodiments, the pedal 20 can also rotate along the horizontal direction, so that when the elevator is running, the pedal 20 is not easy to be unfolded into a working state due to the inertia and gravity generated by the up-and-down movement of the elevator car, and the problems of affecting passengers in the elevator car, occupying the car space and the like are avoided.

Referring to fig. 6 to 8, the pedal 20 includes a first pedal 21 and a second pedal 22, one of the first pedal 21 and the second pedal 22 is connected to the mounting plate 10, the other is connected to the support plate 30, and the first pedal 21 and the second pedal 22 are movably connected.

Since the first pedal 21 and the second pedal 22 are movably connected, the second pedal 22 can freely move in a direction away from the mounting plate 10 or in a direction toward the mounting plate 10. When the second pedal 22 is far away from the mounting plate 10, the length of the pedal 20 in the horizontal direction is correspondingly increased, the treading area is correspondingly increased, and the area of the pedal 20 which can be treaded by a user is more when the second pedal 22 is far away from the mounting plate 10, so that the user can walk conveniently; when the second pedal 22 is close to the mounting plate 10, the space occupied by the pedal 20 can be reduced, the inner space of the elevator car is vacated, and the pedal 20 can be more conveniently stored after rotating.

Further, one end of the second pedal 22 protrudes into the first pedal 21 and is movable along the first pedal 21. One end of the second pedal 22 extending into the first pedal 21 is provided with a first limiting section 221, a second limiting section 211 is arranged in the first pedal 21, and the first limiting section 221 can be abutted with the second limiting section 211 so as to limit the second pedal 22. Therefore, the second pedal 22 can be accommodated in the first pedal 21, and when the pedal 20 is in the folded state, the second pedal 22 does not occupy additional space, so that the pedal 20 can be conveniently accommodated. The cooperation of the first limiting section 221 and the second limiting section 211 can prevent the second pedal 22 from being excessively extended, so that the problem that the second pedal 22 falls is avoided.

Taking the example that the first pedal 21 is connected to the mounting plate 10 and the second pedal 22 is connected to the support plate 30, the first pedal 21 is abutted to the mounting plate 10 during the deployment of the pedal 20, and the second pedal 22 can move in the horizontal direction with respect to the first pedal 21. One end of the second pedal 22 extending into the first pedal 21 is bent to form a first limiting section 221, and along with the movement of the second pedal 22 in a direction away from the mounting plate 10, the first limiting section 221 can be abutted with the second limiting section 211 to limit the second pedal 22. Thus, the first pedal 21 and the second pedal 22 are partially overlapped, and the overlapped part is positioned in the middle of the pedal 20, namely, the position where the pedal is mainly stepped, so that the strength of the part is higher, and the safety of the pedal 20 is higher. When the pedal 20 is folded, the second pedal 22 moves toward the mounting plate 10, and the first and second stopper sections 221 and 211 are disengaged.

It will be appreciated that the connection between the first pedal 21 and the second pedal 22 is not limited to the above-described connection. In other embodiments, one end of the first pedal 21 is rotatably connected to one end of the second pedal 22, and the second pedal 22 can rotate around the end and rotate to a state of being attached to the first pedal 21, so as to reduce the space occupied by the second pedal. When the pedal 20 is in the accommodated state, the first pedal 21 and the second pedal 22 are both parallel to the mounting plate 10, and when the pedal 20 is in the operating state, the second pedal 22 can be rotated to a position parallel to the first pedal 21, so that the first pedal 21 extends to be stepped on by a user.

Further, the pedals 20 are rectangular, one shorter side of the pedals 20 is connected with the mounting plate 10, the pedals 20 can rotate around the shorter side, when the pedals 20 are in the folded state, the pedals 20 are parallel to the mounting plate 10, and the side is positioned at the bottom or the top of the pedals 20; when the pedal is in the working state, the pedal is positioned in the horizontal direction.

By this arrangement, the narrower side of the pedal 20 is connected to the mounting plate 10, and the longer side of the pedal 20 after deployment, the area of the pedal 20 is increased in a limited space. When the pedal 20 needs to be unfolded or folded, the pedal 20 connected with the mounting plate 10 through the narrow edge can be unfolded or folded under the action of gravity due to the fact that the pedal is long, and the pedal is more convenient and labor-saving.

It will be appreciated that in other embodiments, the pedal 20 may be square with the same sides, kidney-shaped, etc., and the shape of the pedal 20 is not limited to the rectangular shape described above.
