Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an escalator device capable of transporting wheelchairs for physically handicapped people as well as general passengers, and in particular to a configuration of a deep wheelchair loading space. be.

[Prior Art] For example, there is an escalator device that can transport wheelchairs, as shown in Japanese Patent Publication No. 56-41555, but it does not have deep steps for wheelchairs between steps for general passengers. The wheelchair is transported by the wheelchair steps, and the wheelchair steps are configured to circulate within the main frame of the escalator device together with the general passenger steps.

[Problem that the invention seeks to solve]

In the conventional escalator device as described above, the reversing radius during the reversing operation to circulate the long-depth wheelchair steps becomes large and a deep main frame is required, which limits the installation location in terms of securing installation space. There was a problem.

This invention was made to solve such problems, and provides an escalator device that can transport general passengers and wheelchairs without providing wheelchair steps with a long depth dimension or increasing the depth of the main frame. With the goal.

[Means for solving problems]

In the escalator device according to the present invention, a wheelchair step having a movable mechanism is provided on a step similar to a step for general passengers, and the wheelchair step always forms a normal tread and is operated in circulation to transport general passengers, A wheelchair tread is constructed through the operation of a movable mechanism during wheelchair transport.

[Effect]

In this invention, when the wheelchair is transported, the movable mechanism is brought into operation via the connection mechanism provided at the end of the main frame, and the wheelchair steps form the wheelchair treads.

In other words, there is a wheelchair step 3' between the first type steps 3.
are arranged and connected by a step chain 4, and the main frame 1
The first wheelchair steps 3, 3' are circulated in the circulation path 2 via the step chain 4 by a drive device (not shown) provided in the wheelchair. The front wheels 3b, 3'b are guided by the front wheel rail 5, and the rear wheels 3c, 3'c are guided by the rear wheel rail 6. It moves horizontally, and in the middle part of the outward path 2a, it moves obliquely while maintaining a horizontal attitude. In addition, when transporting general passengers, the treadle 3
1 is placed in a lowered position with respect to the wheelchair step 3' to form a normal tread, and the connecting device 8 is deenergized and placed in the lowered position shown in FIG. The escalator is placed below and normally operates.

On the other hand, wheelchair users are transported as follows. A case in which a wheelchair user is transported from the lower end of the main frame 1 to the upper end will be described below. i.e. escalator control device (not shown)
is manually operated, and the second type step 3' is stopped at a predetermined position at the lower end of the main frame 1, where the plug receiver 32g faces the biasing mechanism 9. Next, 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 32 is connected to the control device via the cord 7d. In this state, the wheelchair user gets on the wheelchair step 3' and the adjacent type 1 step 3 as shown in FIG. 1, and when the control device is operated, the escalator is operated. Then, as the wheelchair step 3' moves, the biasing mechanism 9 comes off the movable body 8c and moves together with the wheelchair step 3', and the cord 7d is pulled out from the reel 7a. Also,
The movable mechanism 32 is energized by the control device and the electric motor 3
2e rotates, the pivot pieces 32c are displaced in the direction away from each other by the threaded rod 32d, and the tread 31 is raised as shown in FIG. 8, and the tread 31 is placed in a position corresponding to the tread of the adjacent first type step 3. Then, a wheelchair tread is formed. The tread 31 gradually rises as the wheelchair step 3' moves from horizontal movement to inclined movement, and on the outward journey 2a, as shown in FIG. A space is formed. The wheelchair is transported in a stable condition. When the wheelchair step 3' approaches the upper end of the main frame 1, the tread plate 31
On the other hand, the electric motor 32e is rotated in the opposite direction to when the tread plate 31 is raised and is lowered, moving with the adjacent type 1 step 3 while maintaining a horizontal space as shown in FIG. It stops at a predetermined position at the upper end of 1. When the wheelchair user gets off the escalator, the escalator is driven downward, the biasing mechanism 9 moves together with the wheelchair steps 3', and the cord 7d is wound onto the reel 7a by the mainspring 7c. Next, when the wheelchair step 3' approaches a predetermined position at the lower end of the main frame 1, the connector 9 engages with the engaging portion 8d of the movable body 8c, and the wheelchair step 3' stops. Then, the connecting device 8 is energized, the movable body 8c is lowered by the rotation of the servo motor 8a, and the energizing mechanism 9 disengages the plug receiver 32g. This resumes normal operation of the escalator. In addition, when the biasing mechanism 9 is fitted into the plug receiver 32g, the tread plate 31 corresponds to the tread surface of the adjacent type 1 step 3 even when the wheelchair step 3' is moving downward in the same way as when it is moving upward. Since the main frame 1 operates in a horizontal manner and forms a horizontal space, it is also possible to transport a wheelchair user from the upper end to the lower end of the main frame 1. In this way, there is no need to provide deep steps for loading wheelchairs, and an escalator device that can be easily installed without increasing the size of the main frame 1 can be obtained.

Further, in the above embodiments, it has been explained that the wide loading space is formed by the two steps when transporting a wheelchair, but it goes without saying that this is not limited to transporting a wheelchair.

〔Effect of the invention〕

As explained above, the present invention provides a wheelchair which is provided with a movable mechanism and which is normally operated in a circulation path of the main frame to form a tread, and which forms a tread for the wheelchair through the operation of the movable mechanism when transporting the wheelchair. Steps are provided, and a connecting device is provided at the outgoing end of the main frame circulation path to be connected to the movable mechanism during transport of the wheelchair so that the movable mechanism is in an operating state. As a result, a space for the wheelchair can be obtained using the wheelchair tread, and the wheelchair user can be transported without any problems. Also, there is no need for steps with special external dimensions for wheelchairs, and the reversal radius of the steps can be increased. Since there is no main frame, the main frame does not have to be enlarged, and the escalator device can be easily installed with few restrictions on the installation location.
