Further, the lower step 9 has a built-in wheel stop 20 near the riser 19C of the tread plate 9F, and projects upward from the tread plate 9F by well-known driving means (not shown) and is stored in the original state. It is configured as follows.
Further, a detector 21A for detecting that the bollard 20 has been correctly projected and a detector 21B for detecting that the bollard 20 has been correctly stored are built in, and the detection signal is used as a driving condition.

On the other hand, near the upper and lower floors 3A and 3B, there are staff call buttons 22A and 22B for calling a staff respectively.
22B, an operation panel 23A provided with an operation mode switching key switch and a start button after the wheelchair 10 is mounted.
23B, and restart buttons 24A and 24B for restarting after the wheelchair 10 is lowered are installed.

Next, the ascending operation of the escalator configured as described above from the lower floor 1 to the upper floor 2 will be described.

During normal operation, each of the steps 7 to 9 is also a general step 4.
Similarly, the general passengers are put on the treads 7F to 9F, so that the appearance is the same as the general steps 4 and has the same function as the general steps 4.

During normal driving at 30 m / min, the wheelchair 1
When trying to use 0, the operation is performed according to the procedure shown in FIG.

The wheelchair user 25 calls the nearby attendant 26 or presses the attendant call button 22A near the entrance / exit to call the attendant 26.

The called clerk 26 prohibits general passengers from getting in and confirms that all passengers have got off.
The normal operation mode is switched to the wheelchair transport operation mode by the key switch of the operation panel 23A. By operating the key switch, the escalator that has been operating normally decelerates, and the specific step 6 stops on the entrance floor 3A side. Specific steps 6 when stopped
All of the treads 7F to 9F appear in a horizontal state (FIG. 3), and at this time, the treads 7F to 9F and the base 12 and the intermediate base 13S are connected by connecting mechanisms 16 to 18 so that the wheelchair mounting space is reduced. Is secured.

After confirming that the specific step 6 has stopped, the staff 2
6 pushes the wheelchair 10 and gets on the fixed position of the continuous horizontal treads 7F to 9F of the specific step 6 (FIG. 5).

Thereafter, when the clerk 26 presses the start button on the operation panel 23A, the vehicle stop 20 projects from the tread 9F (FIGS. 3 and 6). The correctness of the wheel stop 20 is detected by the detector 21A in the step 9 (FIG. 3). If not correct, the attendant again presses the start button of the operation panel 23A.
If it protrudes correctly, the controller (not shown) activates the escalator on condition of the signal of the detector 21A. Therefore, the escalator is not activated in a state where the wheel stop 20 is not correctly projected.

The top of the specific step 6 is a guide rail 12A,
When entering the sloping section from the horizontal section of 12B, the escalator starts accelerating and reaches a normal operating speed of 30 m / min (FIGS. 7 and 8).

The specific steps 6 are guide rails 12A and 12B.
When the vehicle approaches the upper part of the inclined portion, the vehicle starts to decelerate, and stops in a state where the treads 7F to 9F are horizontally continuous in front of the upper exit floor 3B (FIG. 9).

On condition that the specific step 6 is stopped, each of the steps 7F to 7F
9F and the base 12 and the intermediate base 13S
The connection is released by releasing the vehicle stop 18 and the vehicle stop 20
Is stored in the original position, and the normal storage position of the wheel stop 20 is detected by the detector 21B (FIG. 3). At the same time, clerk 26
Push down the wheelchair 10 (Fig. 10), and then 2
When the user presses the restart button 24B, the controller (not shown) restarts the escalator under the condition of the signal from the detector 21B, and resumes the normal operation at a speed of 30 m / min.

If the car stop 20 is not stored at the original position, the escalator does not restart, so that the car stop 20 and the entrance floor 3B will not be damaged by restarting while protruding the car stop 20. In order to correctly store the bogie 20 in the original position, the clerk 26 operates the key switch of the operation panel 23B or the bogie drive switch provided in parallel with the restart button 24B to perform the storing operation of the bollard. Press the restart button 24B to restart the escalator.

The above description is for the ascending operation of transporting the wheelchair 10 from the lower floor 1 to the upper floor 2. However, in the case of the descending operation of transporting from the upper floor 2 to the lower floor 1, similarly to the above procedure, the clerk call button 22
B, the wheelchair 10 can be transported by operating the key switch of the operation panel 23B, the start button of the operation panel 23B, and the restart button 24A. However, in the case of the descending operation, the projecting timing of the wheel stop 20 is different from that in the ascending operation. That is, when the specific step 6 has stopped at the upper entrance, the wheel stop 20 projects so that the wheelchair 10 does not protrude from the end of the step 9F of the lower step 9 when the user enters the wheelchair.

According to the embodiment, the wheelchair 10 when driving uphill
At the time of start-up after mounting, the escalator is started under the condition that the wheel stop 20 projects, so that even if there is a shock at the time of start-up, the wheelchair 10 does not slip off from the specific step 6.
In addition, since the acceleration of the driving speed is performed after passing through the horizontal portions of the guide rails 12A and 12B and entering the inclined portion, there is no change in the moving direction (from the horizontal portion to the inclined portion) during the acceleration, so that it is safe.

Also, when the vehicle is descending, the wheelchair 10 is mounted after the wheelchair 20 projects, so that there is no fear that the wheelchair 10 is pushed too much and the wheelchair 10 falls down from the specific step 6, so that it is safe. Furthermore, since the regular projection and storage of the bollard 20 are set as conditions for activation, it is possible to avoid a loss of the bollard function due to the movement of the bollard 20 even though it is not at a proper position, and to prevent the destruction of the bogie mechanism. be able to.

In the embodiment, the specific step 6 is stopped at each entry / exit and the wheelchair 10 is entered / exited.
The present invention can be applied to a case where the vehicle is stopped at the time of getting on and the vehicle is driven at a low speed when getting off, or the wheelchair 10 is driven at a low speed without stopping at both sides of the vehicle.

That is, when stopping at the time of getting in and driving at a low speed when getting off, the operation after * 2 in FIG. 4 may be changed.
In this state, the bogie 20 is stored, and the connection of each tread is released.
After lowering the wheelchair 10, the restart button 24
By performing the operation of B (24A), the vehicle returns to the normal operation on condition that the vehicle stop 20 is stored.

Further, when the vehicle is driven at a low speed without stopping on both sides of the vehicle, the operation after * 1 in FIG. 4 may be changed.
The connection of the treads may be performed while the rider 0 is riding on the vehicle, and the stop 20 may be protruded by a staff member operating the start button of the operation panel 23B, and the escalator may be accelerated on the condition of the protrusion. When the wheelchair 10 is lowered, the operation after * 2 in FIG. 4 described above may be performed.
