Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an escalator device in which steps for a wheelchair are provided between steps for general use, and in particular to improving the efficiency of transporting a wheelchair.

[Prior art]

First, based on Figure 1, for example,
The conventional escalator device shown in the publication will be explained.

In the figure, 1 is the main frame of the escalator device, 1a is the lower entrance provided at the lower end of the main frame 1, 1b is the upper entrance provided at the upper end of the main frame 1, and 2 is the endless main frame. A conveyor belt provided in a frame 1 and operated in circulation; a general step 3, in which a large number of steps are connected to each other to form the conveyor belt 2; a general step 4, which has a deeper depth dimension than the general step 3, so that a wheelchair can be loaded thereon; A wheelchair step 5 is connected to the general steps 3 and arranged between the general steps 3, and is provided near the lower entrance 1a of the main frame 1 and is pressed by the wheelchair step 4. A stop switch 6 is a stop switch provided near the upper entrance 1b of the main frame 1 and pressed by the wheelchair steps 4.

That is, the conveyance belt 2 is normally connected and operated in circulation, and general passengers are conveyed by the general use steps 3 and the wheelchair steps 4. Further, a wheelchair user is transported by the wheelchair steps 4, and in this case, the escalator is operated as follows. That is, the normal operation is switched to the wheelchair operation by human operation. Then, when a wheelchair user is to be transported from the lower entrance 1a to the upper entrance 1b, the escalator is operated upward and the stop switch 5 is pressed by the wheelchair step 4, so that the wheelchair step 4 is moved downward. It stops at the boarding gate 1a.
When the wheelchair user gets on the wheelchair steps 4 in this state, the escalator is again operated upward by manual operation, the stop switch 6 is pressed by the wheelchair steps 4, and the wheelchair steps 4 are placed at the upper entrance 1b. A wheelchair operating device (not shown) is provided which is configured to stop and allow the wheelchair user to disembark. However, when transporting a large number of wheelchair users in one direction, for example in the upward direction, the transport belt 2
When there is only one wheelchair step 4 inside, the escalator is restarted after the first wheelchair user is transported, and the next wheelchair user waits until the wheelchair step 4 reaches the lower entrance 1a. As a result, there is a problem that the conveyance capacity becomes small. It is also possible to provide three or more wheelchair steps 4 in the conveyance belt 2, but in this case, the escalator stops while the first wheelchair user is being conveyed to allow the next wheelchair user to board. Therefore, there is a problem that the wheelchair user feels uncomfortable for the first time, and there is also a problem that the manufacturing cost increases due to the large number of wheelchair steps 4.

[Summary of the invention]

This invention solves the above-mentioned drawbacks, and aims to provide an escalator device that can efficiently transport wheelchair users by providing wheelchair steps in the transport belt at positions that bisect the transport belt's length. .

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

In the figure, the same symbols as in Figure 1 indicate corresponding parts, 2a

A return button similar to the return button 10 provided at ' is a stop button provided at the upper entrance 1b, 13 is a rise button provided at the lower entrance 1a, 13' is a rise button provided at the upper entrance 1b, and 14 is a rise button provided at the lower entrance 1a. A lowering button 14' is a lowering button provided at the upper entrance 1b, and 15 is a stop switch 15 fixed in the main frame 1 on the lower entrance 1a side and facing the cam 8 in the upward direction during operation of the wheelchair. ' is stop switch 1
A stop switch 16 is similar to 5 and is provided corresponding to the upper entrance 1b, and 16 is a stop switch fixed in the main frame 1 on the lower entrance 1a side and facing the cam 8 to stop the wheelchair in the downward direction when operating. The switch 16' is similar to the stop switch 16 and is installed corresponding to the upper entrance 1b. The switch 17 is a rising operation relay. 17a and 17b are the normally open contacts of this, and 17c is the normally closed contact. , 18 is a descending operation relay, 18a and 18b are its normally open contacts, respectively.
18c is a normally closed contact, 19 is a rising operating device, 20 is a descending operating device, 21 is a switching button 9, 9', a switching relay 11, a stop switch 15, 15', 1
A wheelchair driving device mainly composed of 6, 16′,
22 is a drive device provided on the main frame 1 and engages with the chain 2a to drive the conveyance belt 2; (+) and (-) are power supplies.

That is, when either the up button 13 or 13' is pressed while the switching relay 11 is deenergized and the stop button 12 or 12' is not pressed, (+)-12-12'-13 -18c-
11b-17-(-) or (+)-12-12'-
The ascending operation relay 17 is energized by the circuit 13'-18c-11b-17-(-). As a result, contacts 17a and 17b are closed and contact 17c is opened. By closing contact 17a, (+)-12-12'-17a-18c-11b-
The ascending operation relay 17 is self-held by the circuit 17-(-). In addition, when the contact 17b is closed, the drive device 22 is energized via the lift operation device 19 by the (+)-17b-19-22-(-) circuit, and the conveyance belt 2 is operated in circulation. Steps 3,
A normal operation is carried out in which general passengers are transported by the wheelchair steps 4. In addition, during normal operation, cam 8
Although the stop switches 15, 15' are pressed, the upward operation relay 17 is not deenergized because the contact 11b is closed. Further, the normal operation in the descending direction is carried out in almost the same manner as in the ascending direction, so a detailed explanation will be omitted, but when either of the descending buttons 14, 14' is pressed, the descending operation relay 18 is energized, and the descending operation device 20 is activated. This is achieved by energizing the drive device 22 through the power supply. When transporting a wheelchair user, it is operated as described below. In other words, when either switch button 9 or 9' is pressed (+)-9-10-10'-11-(-)
Or, the switching relay 11 is energized by the (+)-9'-10-10'-11-(-) circuit, and the contact 1
1a is closed, and contacts 11b and 11c are each opened. When the contact 11a is closed, the switching relay 11 is self-held by the (+)-11a-10-10'-11-(-) circuit.
Now, suppose that the escalator is normally operating in the upward direction and the changeover button 13 is operated to transport a wheelchair user in the upward direction. Therefore, when it is pressed and released, the ascending operation relay 17 is deenergized, contacts 17a and 17b are opened, and contact 17c is closed. Then, by opening the contact point 17b, the ascending operation device 19 is deenergized, the escalator is stopped, and the wheelchair steps 4 are turned off by the stop switch 1.
5 or 15' and stop. At this time, when the stop switch 15 is pressed first, one of the wheelchair steps 4 stops at the lower entrance 1a as shown in FIG. 2, and the wheelchair user immediately gets on the wheelchair step 4. Further, when the stop switch 15' is pressed first, one wheelchair step 4 stops at the upper entrance 1b, but at this time, the other wheelchair step 4 stops near the lower entrance 1a in the main frame 1. When the rise button 13 is operated and closed, (+)-12-
12'-13-18c-15-15'-17-(-)
The rising operation relay 17 is energized by the circuit of
The driving device 22 is energized by the (+)-17b-19-22-(-) circuit and the conveyor band 2 is driven upward, and when the other wheelchair step 4 moves and the stop switch 15 is pressed, the lower Since the vehicle stops at the entrance 1a, the wheelchair user gets on the wheelchair steps 4. Then, when the up button 13 is pressed again, (+) -12-12'-13-18c-15-1
Rising operation relay 1 by circuit 5'-17-(-)
The conveyor band 2 is operated upward through the biasing force 7. When the stop switch 15' is pressed by the wheelchair step 4 on which the wheelchair user is riding, the lift relay 17 is deenergized, the conveyor band 2 is stopped, and the wheelchair step 4 passes the stop switch 15'. The wheelchair user stops and gets off the wheelchair steps 4, thereby achieving upward transportation of the wheelchair user. Further, when transporting a wheelchair user in the downward direction, the operation is almost the same as when transporting the wheelchair user in the upward direction, so a detailed explanation will be omitted, but the switch button 9,
9' is operated to stop the wheelchair step 4 at the upper entrance 1b through the energization of the switching relay 11, allowing the wheelchair user to board the wheelchair, and the lowering button 14' is pressed to lower the conveyor belt 2 and remove the wheelchair. When the stop switch 16 is pressed by the wheelchair step 4 carrying the user, the conveyor belt 2 is stopped, allowing the wheelchair user to get off at the lower entrance 1a.

Furthermore, when transporting a large number of wheelchair users in one direction, one wheelchair step 4 is used at one entrance.
When the first wheelchair user is loaded and transported and reaches the other entrance, the other wheelchair step 4 has reached the vicinity of one entrance. Therefore, by operating the up button 13, 13' or the down button 14, 14' to drive the conveyance belt 2 over a short distance, the next wheelchair user can be placed on the other wheelchair step 4, and the conveyance belt 2 is wasted. To provide an escalator device which can efficiently transport a wheelchair user without requiring a lot of driving, prevents the wheelchair steps 4 from stopping in the middle of transport, and can be manufactured at low cost.

In short, the wheelchair operation device 21 switches the escalator from normal operation, and one of the two wheelchair steps 4, each provided at a position that bisects the length of the conveyor belt 2, is automatically stopped at one entrance to use the wheelchair. Place the person on board and press the rise button 13, 13'.
By operating either of the lowering buttons 14, 14', the wheelchair user is transported and automatically stopped at the other entrance, and when one wheelchair step 4 reaches the other entrance, the wheelchair user is transported and stopped automatically at the other entrance. Steps 4
is located near one of the entrances, allowing wheelchair users to be transported continuously and efficiently. In addition, since the wheelchair steps 4 do not stop in the middle of the wheelchair operation, the wheelchair user does not feel uncomfortable, and since only two wheelchair steps 4 are required, it is inexpensive and transports the wheelchair user. It is possible to get an escalator.

〔Effect of the invention〕

As explained above, the present invention provides two wheelchair steps, each located at a position half the length of an endless conveyor belt that is operated in a circular manner, and operates through manual operation to move one of the wheelchair steps to one side. The wheelchair is equipped with a driving device that allows the wheelchair to be stopped at one entrance and then operated and stopped at the other entrance.

As a result, the wheelchair user can be transported continuously and efficiently, the wheelchair steps do not stop during the wheelchair operation, and the wheelchair user does not feel uncomfortable, and the wheelchair user can be transported efficiently. The present invention is to realize an escalator device that is possible and can be manufactured at low cost.
