Reference numeral 8 denotes a wheelchair step group interposed between a plurality of normal steps 5, and as shown in FIG. 1, the wheelchair step group 8 is seated by a wheelchair user 9 with an intermediate portion inclined. An inclined step 80 for avoiding interference of the wheel and the footrest of the wheelchair 10, a fork step 81 which is disposed adjacent to the rear of the inclined step 80 and has a built-in reciprocating fork protruding rearward, and a rear part of the fork step 81 A movable step which is arranged adjacent to the fork and is combined with a fork during wheelchair driving to ascend to form the same horizontal plane as the tread surface of the fork step, and a wheel stop step 82 for preventing a drop of the wheelchair 10 by preventing a wheelchair from projecting from the tread surface of the movable step. During the normal operation of the escalator, the escalator circulates and moves in the same normal form as the normal steps 5, and during the operation for a wheelchair, the wheelchair of the wheelchair user 9 is used. Has a function of transformation operations can be mounted wheelchair form 10.

A driving force transmitting mechanism (not shown) for transforming these steps is provided inside the above-mentioned tilting step 80, fork step 81, and wheel stop step 82.
This driving force transmission mechanism operates based on engagement with a device (not shown) installed in the lower machine room 1A and the upper machine room 1B.

Reference numeral 11 denotes a wheelchair operation button mounted on the inner surface of the balustrade 3 near the entrance floor 1D. The wheelchair operation button 11 includes a wheelchair operation switch 110 for switching the operation of the escalator from normal operation to wheelchair operation. A wheelchair operation start switch 111 is provided near the entrance floor 1D to slowly start the escalator in which the wheelchair steps 8 are temporarily stopped.

Reference numeral 12 denotes a lower machine room 1A and an upper machine room 1B.
As shown in FIG. 2, the fence 12 is provided with a plurality of columns 120, 120A, 120B, and 120C provided on both sides of the floor 1D. A chain 121 detachably mounted between the upper surface and the upper surface of the support 120A, the support 120B and the support 1
20C, and a plurality of piers 122 laid side by side with each other.
Of the entrance floor 1D from the side of the vehicle.

Reference numeral 13 denotes a pole which is buried in the lower machine room 1A and the upper machine room 1B so as to be able to protrude and retract. As shown in FIGS. A groove 15 fitted and guided by the protrusion 14 of the room 1A or the upper machine room 1B is formed in a substantially L-shape, and protrudes upward through the center of the entrance floor 1D based on a manual operation of a staff (not shown). In addition, it has a function of forming a width between the support 120A and the support 120C to block the wheelchair user 9 from entering the front of the floor 1D. As shown by the arrow in FIG. 3, this width is formed to a length that only blocks the entry of the wheelchair user 9, and is a length that allows general passengers to freely enter the entrance floor 1D. The escalator with steps can contribute to the transportation capacity during wheelchair driving.

Next, the operation will be described. For convenience of explanation, the case of ascending operation will be described. First, in the case of normal driving, the wheelchair step group 8 circulates and moves in a normal form similarly to the normal step 5, and ordinary passengers are lowered from the floor 1D, which is the lower floor, to the upper floor. It is transported to the entrance floor 1D. At this time, as shown in FIG. 1, the pole 13 is retracted and accommodated in the lower machine room 1A and the upper machine room 1B, and the upper surface forms a part of the entrance floor 1D. Smooth entry into floor 1D.

Next, the case of wheelchair driving will be described. When the wheelchair user 9 comes to the floor 1D on the lower floor, the clerk operates the wheelchair driving switch 1 of the wheelchair driving button 11.
By operating 10, the escalator switches from the normal operation to the wheelchair operation and performs the deceleration operation. Next, the lower floor floor 1
When the wheelchair step group 8 moves horizontally at a low speed at D, the in-process device operates, and the driving force transmission mechanism of the wheelchair step group 8 sequentially engages with the operated in-process device while moving. As the intermediate portion of the inclined step 80 is inclined, the fork of the fork step 81 projects and merges with the movable step of the wheel stop step 82 to form a part of a wheelchair form. Then, the wheelchair steps 8 are temporarily stopped in front of the entrance floor 1D, and the wheelchair user 9 who sits on the wheelchair 10 enters the temporarily stopped wheelchairs 8.

Then, when the clerk pulls up the retracted pole 13, the pole 13 projects through the center of the entrance floor 1D while the groove 15 is guided by the projection 14, and rises up.
A space is formed between the pole 13 and the pillars 120A and 120C that allows only general passengers to enter the entrance floor 1D, and the subsequent wheelchair user 9 is prevented from entering the front of the entrance floor 1D. You. Further, the approach to the entrance floor 1D from the side of the subsequent wheelchair user 9 is eliminated by the chain 121 and the pier 122 of the fence 12. The protruding pole 13
Is rotationally operated, and the end of the groove 15 is locked to the protrusion 14, so that the protrusion is fixed.

Next, when the clerk operates the wheelchair operation start switch 111 of the wheelchair operation button 11, the escalator starts slowly, and the driving force transmission mechanism of the wheel stop step 82 engages with the in-process device to cause the wheel stop to protrude. The operation of the wheel of the wheelchair 10 is regulated. When the wheelchair step group 8 that moves at a low speed starts to move upward from the horizontal movement, the movable step of the wheel stop step 82 rises from the main body as the fork step 81 rises, and the fork step 8 moves.
The escalator is positioned on the same horizontal plane as the tread surface of No. 1 to form a wheelchair-shaped remainder, and thereafter the escalator performs a speed-up operation. Also,
The general passenger who has entered the entrance floor 1D from between the pole 13 and the pillars 120A and 120C is transported to the upper floor by riding on the ordinary steps 5 after the ascending steps 8 for the wheelchairs, and is transported to the upper floor by this transportation. A reduction in the amount of transport during wheelchair driving is reliably prevented.

Next, when the rising wheelchair step group 8 moves to the upper part of the inclined portion 1C, the escalator decelerates and the in-process device operates in the same manner as described above. Then, when the moving wheelchair step group 8 starts to move horizontally from the ascending movement, the movable step of the wheel stop step 82 relatively moves down and is positioned on the same horizontal plane as the tread surface of the main body, and a part of the wheelchair form is changed. It is released.

Next, when the wheelchair step group 8 moves horizontally at a low speed onto the upper floor entrance floor 1D, the wheelchair step group 8 moves.
The driving force transmission mechanism moves and engages in sequence while moving to the operated in-process device, and the inclined intermediate portion of the inclined step 80 swings back to the normal state and is fixed, and the fork step 81 projects. The fork retracts and moves inside, and the projecting wheel stop of the wheel stop step 82 moves and retracts inside, and the wheelchair steps 8 are transformed from the wheelchair mode to the normal mode.

However, the first wheelchair user 9 and the attendant move the wheelchair 10 from the moving wheelchair steps 8 to the floor 1D at the entrance. During this movement, the wheelchair steps 8 and the subsequent normal steps 5 do not stop temporarily, but the treads move while maintaining the horizontal state, so that there is no particular safety problem. After that, the escalator performs a speed-up operation, and the ordinary passenger who has been transported to the upper floor moves from the normal step 5 to the entrance floor 1D.

Next, the attendant descends on the floor 1D on the lower floor, turns the pole 13 in the protruding and fixed state in the horizontal direction, and performs the retreat operation. Then, the pole 13 retreats and descends from the entrance / exit floor 1D into the lower machine room 1A while the groove 15 is guided by the protrusion 14, and the subsequent wheelchair user 9 is allowed to enter the entrance / exit floor 1D. However, the subsequent wheelchair user 9
Is present, the above operation is repeated, and if there is no subsequent wheelchair user 9, the escalator switches from wheelchair driving to normal driving.

According to the above configuration, the pole 13 which becomes an obstacle when the wheelchair user 9 is transported protrudes from the floor 1D and rises and exits between the poles 120A and 120C. Since the width for blocking only the approach to the floor 1D is formed, it is possible to reliably prevent the misunderstood subsequent wheelchair user 9 from riding on the normal steps 10 and causing a fall accident. In addition, the following wheelchair users 9
Since there is no need to always arrange a dedicated staff member for blocking entry into D on the entrance floor 1D, it is possible to greatly reduce labor costs. Furthermore, the pole 1 in the protruding state
Since 3 does not hinder the use of the escalator by ordinary passengers, it is possible to reliably prevent a decrease in the transport capacity of the escalator during wheelchair driving.

In the above embodiment, the fence 1 is attached to the entrance floor 1D.
2 is shown, but if the subsequent wheelchair user 9 can be prevented from entering the floor 1D, the pole 13 may be omitted. Further, in the above-described embodiment, the pole 13 is shown and retracted based on the manual operation of the staff, but it is needless to say that the present invention is not limited to this.

Next, FIG. 7 shows another embodiment of the present invention. In the figure, reference numeral 16 denotes an intrusion prevention fence erected on the entrance floor 1D. A plurality of columns 160, 160A, 160B, 1 standing on both sides
60C, a plurality of piers 161 arranged side by side between the support 160 and the support 160A, the support 160B and the support 160.
C and a plurality of piers 161 arranged side by side with
Wheelchair user 9 pivotally attached to 60A / 160C
And an opening / closing fence 162 that closes based on the operation of the attendant during transportation of the vehicle and blocks other wheelchair users 9 from entering the floor 1D. Further, as shown by the arrow in FIG. 7, the width between the opening / closing fences 162 is formed so as to block only the entry of the wheelchair user 9, and allows general passengers to freely enter the entrance floor 1D. The length of the escalator with a wheelchair step can be reliably prevented from decreasing when the wheelchair is driven.

In this embodiment, the same operation and effect as those of the above embodiment can be expected, and it is apparent that the structure of the lower machine room 1A and the upper machine room 1B can be prevented from becoming complicated.

In the above embodiments, the fence 12 and the pole 1
3 and the intrusion prevention fence 16 are shown, but the invention is not limited to this as long as it can block the other wheelchair users 9 from entering the floor 1D when the wheelchair user 9 is transported.
