In such a wheelchair-equipped escalator, at least one special step for wheelchair mounting is provided among a number of steps that are connected endlessly and circulates, and a wheelchair user is mounted for transportation. . This special step operates as a step for general passengers during normal driving, and operates to secure a space for wheelchair loading during wheelchair operation, so that both general passengers and passengers using wheelchairs can use it as a combined use. It is common to have

When a wheelchair user is to be placed on an escalator during normal driving, first the general user is completely transported, and then the mode is switched to wheelchair driving, and the special step comes to the entrance / exit where the wheelchair user is located. When it does, it is automatically stopped. Similarly, when the wheelchair user gets off at the other entrance / exit, the escalator is once stopped, the wheelchair user is lowered, and then the escalator is returned to the normal operation. It is supposed to do.

[0004]

However, in the conventional driving method, since the escalator is temporarily stopped at each entrance / exit of the wheelchair when driving the wheelchair, the driving efficiency is poor and the service for general users is also deteriorated. become. In addition, when a wheelchair user gets off the escalator, it is possible to automatically return to normal driving after stopping the escalator to improve driving efficiency. It was very dangerous and was not the preferred method. Further, there is a problem that it is difficult for a staff member to operate because there are many switches and buttons to be operated when driving a wheelchair. Furthermore, since it will be attached to the balustrade where such switches and buttons are easy to operate,
The design of the parapet was spoiled. In particular, when the balustrade has a transparent panel, the design is significantly impaired, and it is difficult to attach switches and buttons to the thickness of the transparent panel.

Therefore, an object of the present invention is to provide a wheelchair-equipped escalator which can safely transport wheelchair users and improve driving efficiency, is easy for a staff member to operate, and is excellent in design. Especially.

FIG. 4 shows a state in which the special steps 10, 11 and 12 are urged and the vehicle is running on an inclined portion such that a wheelchair or the like can be mounted. 5 and 6 are views showing the appearance of the special steps.
Shows a normal driving state, and FIG. 6 shows a state in which a wheelchair or the like can be mounted.

The escalator capable of carrying a wheelchair or the like is constructed as described above, and a plurality of steps are connected to each other to secure a space for mounting the wheelchair. In the above-described configuration, the operation operation when the wheelchair operation changeover switch 7 is operated will be described with reference to FIGS. 7 and 8.

First, after confirming that the transportation of general passengers has been completed, when the wheelchair operation changeover switch 7 is operated (step 1), the escalator starts wheelchair operation.

When the wheelchair operation is started and the special step approaches the entrance / exit, the boarding deceleration limit switch 32 operates (step 2), and the motor 30 is inverter-controlled to make it easy for the wheelchair to board and the attendant to board the car with a margin. The escalator is operated at a speed at which the escalator can be operated, for example, 3.5 m / min (step 3). When the boarding is completed, the attendant operates the boarding confirmation button 8 (step 4). When the boarding confirmation button 8 is operated, the escalator is at a normal speed of 30 m.
/ Min (step 5), and the deceleration start limit switch 31 operates near the entrance / exit (step 6). When the deceleration start limit switch 31 operates, the escalator is driven at a speed at which the wheelchair can easily get off, for example, 7.5 m / min (step 7). Here, the speed of the escalator when the wheelchair gets off is preferably higher than the speed when getting on the vehicle. This is because it is possible from the point of view of driving efficiency because the wheelchair itself can obtain the inertial force so that it is possible to get off smoothly, and the operation of the attendant is much easier when getting off than when getting on board. Is.

When it is finally confirmed that the wheelchair has stepped down, the step-down confirmation button 8a is operated (step 8) to return the escalator to normal operation (30 m / min) (step 9).

Here, in step 4, the boarding confirmation button 8
If is not operated, proceed to step 10. When the boarding overrun limit switch 33 operates, the escalator stops (step 11). After the escalator is stopped, by operating the boarding confirmation button 8 (step 12), the escalator returns to the normal running (step 5).

If the down confirmation button 8a has not been operated in step 8, the process proceeds to step 13. When the descending overrun limit switch 34 operates, the escalator stops (step 14). After the escalator is stopped, the escalator is returned to normal operation by operating the descending confirmation button 8a (step 15) (step 9).

As described above, according to the present embodiment, after switching to wheelchair driving, the special steps are called near the entrance / exit so that the passengers can run at a very low speed without stopping the steps when getting on / off the wheelchair. Since the speed of the escalator when getting off the wheelchair is set to be higher than the speed of the escalator when getting in, it is possible to improve the operation efficiency and to provide the boarding confirmation button 8 and the getting-off confirmation button 8a. As a result, it is possible to ensure that the wheelchair loading and unloading operations are performed, so that it is possible to ensure safety for wheelchair users. In addition, when the wheelchair boarding and dismounting operations take time and effort, the escalator is automatically stopped, so even if the escalator is driven at a slow speed when the wheelchair is operated, the escalator can be operated without any worries. .

In this embodiment, the wheelchair operation changeover switch 7, the boarding confirmation driving button 8, and the getting-off confirmation button 8 are used.
a, a wheelchair-driving stop button 8b, and a restart button 8c are provided on the parapet to configure the escalator so that it can respond to wheelchair driving. For example, as shown in FIG. 9, the escalator entrances and exits 2 and 3 are wirelessly connected. A remote control receiver 35 is provided so that the clerk 5 can use the wireless remote control transmitter 36 to perform various wheelchair-driving switches or buttons 7, 8 and 8a.
The command operation corresponding to 8c may be performed.

With such a structure, when it is desired to perform an operation such as an emergency stop, the wireless remote control transmitter can be used without the wheelchair driving stop button 8b nearby.
The stop command can be transmitted to the wireless remote control receiver 35 by the 36, and the wireless remote control receiver 35 that has received the stop command sends a stop command to the wheelchair driving control unit (not shown) to stop the escalator remotely. Can be made. Therefore, the operability of the staff member 5 during wheelchair driving is good, and the wheelchair user can be safely transported. Also, by using the wireless remote control transmitter 36 and receiver 35,
Since it is not necessary to provide various switches and buttons 7, 8 and 8a to 8c, the balustrade of an ordinary escalator (without wheelchair driving function) can be used as it is, and the production time and cost can be significantly reduced. Becomes In addition, even for escalator of various types of parapets such as transparent panel type parapets where it is difficult to attach buttons etc., the escalator that also serves as a wheelchair can be adopted, eliminating the complexity of design, production, management and assembly in standardization. To be done.

Further, as shown in FIGS. 9 and 10, a restriction door 37 is provided at each of the entrances / exits 2 and 3 for restricting the entrance / exit of a person, and the restriction door 37 is also operated by the wireless remote control transmitter 36. By doing so, it is possible to remotely restrict the entry of general passengers who board later, and it is possible to accurately time the boarding permission of general passengers. Normally, after the wheelchair is installed, the normal speed is 30m / min
After moving to, the boarding permission for general passengers is given. By doing so, the entry of general users can be restricted until the wheelchair driving becomes stable (30 m / min), so that the safety of general users can be improved. In addition, although there is a case where a passenger is usually given permission to board by an announcement, the problem that a wheelchair user is distracted and enters without noticing can be solved.

[0024]

As described above, according to the present invention, it is possible to improve the driving efficiency without lowering the operation service for general passengers while ensuring the safety for wheelchair users, and it is easy for the staff to operate and the design is good. It is possible to provide an excellent escalator for wheelchairs.
