In other words, the second type step (3') is placed between the first type step +31, connected by the step chain (41), and connected to the main frame (1).
A drive device (not shown) provided at the step chain (4
) via the first. The second type step f31 (3') is operated in circulation on the circulation path (2). The front wheels (3bXs'b) are guided by the front wheel rails (51), and the rear wheels (3c) (3'c) are guided by the rear wheel rails (61).
The seed step f31 (3') moves horizontally at the end of the outgoing path (2a), and moves obliquely while maintaining a horizontal attitude at the middle part of the outgoing path (2a). In addition, when transporting general passengers, the treadle is zero.
υ is placed in a lowered position relative to the second type step (3') to form a normal tread.

Further, the connecting device (81) is deenergized and placed in the lowered position shown in FIG. 2, the biasing mechanism (9) is placed below the plug receiver (52g), and the escalator is normally operated.

On the other hand, wheelchair users are transported as follows.

A case in which a wheelchair user is transported from the lower end to the upper end of the main frame (1) will be described below. That is, the control device (not shown) of the escalator is manually operated, and the second type steps (three Then, the connecting device (8) is energized, the movable body (8c) is raised by the servo motor (8a), the connector (9) is fitted into the plug receiver (32g), and the movable mechanism G is stopped. is connected to the control device via a cord (7d).

In this state, the wheelchair user enters the second quarter as shown in Figure 1.
When the user steps on the step (3') and the first type step (31) adjacent thereto and operates the control device, the escalator is operated.Then, the movement of the second type step (3') activates the biasing mechanism (9). ) is detached from the movable body (8c) and moves together with the second step (3), and the cord (7d) is pulled out from the reel (7a). Also, the movable mechanism U2 is energized by the control device and the electric motor (32e) is rotated. The pivot pieces (32c) are displaced away from each other by the threaded rod (32d), and the treadle Gυ
is raised as shown in Fig. 8, and the tread Oυ is adjacent to the first
A wheelchair tread is formed by being arranged at a position corresponding to the tread of the gentle step (3).

And the tread 6υ is the 28th! As the step (3') moves from horizontal movement to inclined movement, it gradually rises, and on the outward journey (2a), as shown in Figure 7, a horizontal space for loading a wheelchair is formed with the adjacent type 1 step (3). be done.

The wheelchair is transported in a stable condition. Then, when the second gentle step (three of them approach the upper end of the main frame (1)), the electric motor (32e)
It rotates in the opposite direction to when it ascends and descends, and the adjacent type 1 step (
3), it moves while maintaining a horizontal space as shown in FIG. 10 and stops at a predetermined position at the upper end of the main frame (1). When the wheelchair user gets off the escalator, the escalator is driven downward and the biasing mechanism (
9) moves with the second yontodan (three steps) to the chord (7d
) is wound onto the reel (7a) by the mainspring (7C). Then, when the second 'si step (3') approaches a predetermined position on the lower end of the main frame (1), the connector (9) engages with the engaging part (8d) of the movable body (8c), and the second step (3') approaches the lower end of the main frame (1). 2 steps (3 stops. Then, the connecting device (8) is energized and the movable body (8C) is lowered by the rotation of the servo motor (8a), and the energizing mechanism (9) is connected to the plug receiver (32g). will be withdrawn.

This resumes normal operation of the escalator. In addition, when the biasing mechanism (9) is fitted into the plug receiver (32g), the tread Gυ is moved to the second gentle step (the adjacent 1f11I step even during the three downward movements as well as during the upward movement). (3) Since it operates in correspondence with the tread and forms a horizontal space, it is also possible to transport a wheelchair user from the upper end of the main frame (1) to the lower end. It is possible to obtain an escalator device that does not require the provision of deep steps for loading, prevents the main frame (1) from increasing in size, and can be easily installed.

In addition, by applying the embodiments shown in FIGS. 1 to 10, the connection device <
m is also provided at the upper end of the main frame (1). Plug receiver (3
Even if the biasing mechanism (9) that has been engaged with and raised by the upper end of the biasing mechanism (9) is detached from the plug receiver (3ag) at the upper end and the cord (7d) is wound onto the cord reel device (7), It is clear that the same effect as the embodiments shown in FIGS. 1 to 10 can be obtained.

In addition, as another embodiment, in the embodiments shown in FIGS. 1 to 10, a cord reel device (7), a connecting device (8), and a biasing mechanism (9) are also arranged at the upper end of the main frame (1). , it is possible to transport the wheelchair from the upper end to the lower end by means of the cord reel device or the like at the upper end, and this structure also provides the same effect as the embodiment shown in FIGS. 1 to 10. The gains are obvious.

As explained above, the present invention provides a wheelchair step that is provided with a movable mechanism and is normally driven in circulation through the circulation path of the main frame with the tread fully formed, and that forms a wheelchair tread via the movable mechanism. The main frame is located opposite the outgoing end of the circulation path.
A biasing mechanism is provided which is connected to the movable mechanism and operates the movable mechanism to form a wheelchair tread when the wheelchair is transported.

As a result, the wheelchair treads provide space for the wheelchair and the wheelchair user can be transported without any problems.
In addition, there is no need for steps with special external dimensions for wheelchairs, and the reversal radius of the steps does not increase, so the main frame does not become large, and there are fewer restrictions on the installation location, making it easy to install. This realizes an escalator device.
