Next, the operation of this embodiment configured as described above will be explained.

In the normal operating state of the escalator, the second and third steps 31, 32 are arranged adjacently between the first steps 3, 3;
Like the first step 3, it is connected by a step chain 9. In normal operation, the 7 oak 5 is held under the back surface of the second step 31, the movable frame 83 including the drive mechanism 8 is held at the lower end position, and the engagement rod 76 is engaged. Hole 32j.

The movable step board 32h is held fixed to the third step 32 by engaging with the hole 32g, and the pins 6b and 73b of the blocking fifits 6 and 73 are engaged with the pin holes 42a and 72 of the input body 42.72.
a and forward/reverse movement machine IpI4. The operation of the lock mechanism 7 is prevented.

In this state, call relay 05 is de-energized,
And since the stop command relay 04 is energized, if you press the start switch S1 for normal operation, (+) - stop switch S2 - safety switch edge S5 - safety switch S6T start switch S1 - contact C2b - contact C3d -Relay ci-
The contactor C1 for normal operation is energized by the (-) closed circuit, and its three-pole normally open contact C1a is closed, thereby connecting the motor 21 to the three-phase power supplies R, S, and T, and starting the motor 21. As a result, the first to third type steps 3°31.32 are operated in circulation along the circulation path 2 via the step chain 9.

At this time, the front wheel 3b is moved by the front wheel rail 10.

31b and 32b are 3c-3 by the rear wheel rail 11
10'=32c is guided and the first to third type steps 3.31.
32 moves horizontally at the end of the outgoing route 2a, and moves obliquely while maintaining a horizontal position in the middle part, and general end-users are transported in this state.

On the other hand, when a wheelchair user uses an escalator in the upward direction, the following operation is performed.

That is, when the escalator is normally operated in the upward direction, when a wheelchair user 100 or a caregiver 101 (see FIG. 1) who wishes to use the escalator presses the call switch S3 at the lower end, ( +) - Switch S3 - Relay C3 - Call relay 05 is energized by the closed circuit of (-), closing its normally open contacts C5a to C5c and opening normally closed contact C5d. Self-maintained by closed contact Cllb. When the detection piece P1 attached to the chain 16 running with the escalator faces the proximity switch ID, the proximity switch ID opens, deenergizes the stop command relay 04, and opens its normally open contact C4a. At the same time as the normal operation contactor C1 is deenergized, its three-pole normally open contact C1a opens to cut off the power supply to the electric motor 21, stopping the electric motor 1f121 and stopping the steps. At this time, if the b1 type 2 step 31 has gone too far from the normal position, the detection piece P2 faces the proximity switch ILD and closes it.

Therefore, the low-speed descending operation command relay 08 is energized by the closed circuit of (+)-contact C5c-contact C9c-proximity switch ILD-relay C3-(-), and the closing of its normally open contact C8a causes low-speed descending operation. contactor C3 is energized and closes its three-pole normally open contact C3a.

As a result, three-phase AC power is supplied to the electric motor 22 for low-speed operation, and by starting the electric motor 22, the steps are lowered at a low speed. As a result, when the detection piece P2 comes off from the proximity switch ILD, the proximity switch ILD is turned off, the low-speed descending operation command relay C8 is deenergized, and the contactor C3 is also deenergized, cutting off the power supply to the electric motor 22. At the same time as the step stops, the detection piece P1 faces the proximity switch IL.

That is, the second. The third steps 31 and 32 stop at a horizontally moving position at the lower end of the outgoing path 2a, resulting in the state shown in FIGS. 2 and 3. When an engagement command is generated by the detection piece P1 facing the proximity switch IL, the elevating electric motor @82 is started and rotated together with the movable frame by the screw 82a and the engaging element 83a screwed thereon. 83 rose,
When the movable frame 83 reaches the rising end and the second detector 13 is activated, the rotation of the lifting motor 82 is stopped and the drive @84C is activated.
engages input body 42.72. Also, as the movable frame 83 rises, the rods 6d and 73d are pressed and lifted, so the levers 6a and 73a rotate, and the bins 6b and 73b are moved upward.
are the respective bottle holes 42a and 72 of the input body 42.72.
deviate from a. Next, the electric motor 85 is started and the drive band 84c runs through the chain gears 84a and 84b, and the input body 42 rotates, and the bevel gears 43 and 44a and the spur gear 4 are rotated.
5. 7 due to the engagement of the pinion 45a and rack 5a.
The oak 5 protrudes from below the second step and engages with the retaining piece 32k of the third step 32, and the operation of the third detector 14 cuts off the power supply to the electric motor 85 and stops it.

Further, the input body 72 rotates due to the movement of the drive band 84c,
Pinion 74. The engagement rod 76 comes out of the hole 32g and the engagement hole 32j via the rack 76a, and the riser v 32i
The engagement of the vertical wall 32e is released, resulting in the state shown in FIGS. 9 and 10. Note that since the upper side of the drive band 84c is supported by the elastically supported support member 84d, the drive band 84c is smoothly engaged with the input body 42.72. Then, from the state shown in FIG. 9 and FIG.
When 2 is pressed, the electric lift I! 82 stops. Further, as the movable frame 83 descends, the blocking rock grooves 6 and 73 cause the forward and backward movement mechanism 4. The operation of the lock mechanism 7 is blocked.

When the connection between the second step 31 and the third step 32 is completed, the contact 12a of the first detector 12 and the contact 14a of the third detector 14 are closed, and (+) - contact 14a - contact 12a - relay Cl0 The engagement detection relay C10 is energized by the - (-) closed circuit and is self-held via the 7-oak retirement detection contact 14b in the upper landing area.

As a result, the relay C6 also has (+) - contact C6a - contact C9a - contact 11. It is self-maintained by the C3b-relay C3-(-) circuit.

On the other hand, the low-speed upward operation command relay 07 is energized by the (+)-contact C6b-relay C7-(-) circuit, and its normally open contact C7a is closed, so that (+)X<ff-82
- Safety switch s6 - contact) J, C1c - contact C7a -
A closed circuit of contact C3a-* contactor c2-(-) is formed, which energizes contactor C2 for low-speed ascending operation, closes the three-pole normally open contact C2a in FIG. Power is supplied, the electric motor 22 is started, and the vehicle runs on the steps at low speed.

In addition, as relay 06 is energized, its normally open contact C6d
When closed, the low-speed operation memory relay C1 is activated in the closed circuit of (+)-contact C6d-contact C1e-relay C11-(-).
1 is energized and the relay C1l is self-held at its contact C11a. At this time, normally closed contact C1 of relay C11
Since 1b is opened, call relay 05 is self-held only by contact Cl0a of relay CIO.

Also, the 21st. A wheelchair is loaded into the space formed by the third steps 31 and 32, and the escalator is operated in the upward direction. As the 12th grade step 31 moves to the slope, the movable tread 3211 supported by the 7th oak 5 moves to the third step. 3 It rises relative to the steps 32 and holds the wheelchair f1 loading space horizontally as shown in FIG.

And the second. When the third step steps 31 and 32 travel upward on the outward route 2a and the second type step Fi31 approaches the upper landing and the detection piece P1 faces the proximity switch 2D, the proximity switch 2D opens and the low speed operation stop command relay 09 is deenergized, and low speed operation command relay C6 is also deenergized. At this time, the low speed ascending operation command relay 07 is (+) - contact C5c - contact C9c - proximity switch 2LU - relay C
7- (-) closed circuit maintains the energized state. For this reason,
When the step further moves in the upward direction and the detection piece P2 comes off from the proximity switch 2LU, the proximity switch 2LU is opened and the low speed upward operation command relay 07 is deenergized.
Contactor C2 for low-speed ascending operation is also deenergized, which causes electric I! The power supply to 22 is cut off, and the electric motor 22 is stopped.

At this time, the detection piece P1 faces the proximity switch 2L.

Here, if the step Fi goes too far from the normal position and stops, the detection piece P2 faces the proximity switch 2LD and closes it, causing the (+)-contact and the contact C3c-contact C
Low-speed descending operation command relay C8 is energized by the closed circuit of 9c-proximity switch 2LD-relay 08-(-), and furthermore, (
+) - Switch S2 - Safety switch S5 - Safety switch S6 - Contact C3a - Contact C2cm Contactor C3 - (-
), the contactor C3 for low-speed descending operation is energized, and by closing its three-pole normally open contact C3a, the low-speed electric motor 22 is started in the reverse direction, and the step is lowered at a low speed. Then, when the detection piece P2 comes off from the proximity switch 2LD,
The proximity switch 2LD is opened, the relay C8 is deenergized,
Furthermore, the contactor C3 is also deenergized, the power supply to the electric motor 22 is cut off, and the step stops at its normal position. At this time, the detection piece P1 faces the proximity switch 2L, and the detection piece P1 faces the proximity switch 2L. Third
A voice command to release the combination of steps 31 and 32 is issued. After the escalator has surely stopped, the wheelchair is removed from the top of the steps.

When the release command is sent by turning on the proximity switch 2L, the drive 1IiIJ locking structure 8 provided at the upper end of the forward path 2a is activated and moved upward to move the drive band 84c to the input body 42.7.
2, the electric motor 85 retires the 7 oak 5 and releases the support of the third step 32, and the engagement rod 76 fits into the engagement hole 32j, hole 32°, and the movable step plate 32b is held on the third step 32. After that, Kakeru! [liN 8
is lowered and 7 oak is disengaged, contact 14
b opens and relay 010 is deenergized. As a result, relay 05 is deenergized.

When the wheelchair user presses the start switch S1 again after using the escalator, the contactor C1fJ' is energized.
The electric motor 21 is activated, and the escalator is returned to normal operation and is used to transport general passengers.

As described above, in the embodiment of the present invention, a wheelchair user can be transported without any problems, and since there is no deep step for loading the wheelchair, the main frame 1 does not become large and has a large capacity. It can be installed in Furthermore, since an automatic position correction means is provided for correctly stopping the step at the correct position, the step can be reliably stopped at the normal position, and the operation of the engagement device can also be ensured.

〔Effect of the invention〕

As explained above, according to the present invention, a second step having a protrusively provided seven orifices is provided between the first steps which are continuously arranged and operated in circulation; A third step having a movable tread supported by the 7 oaks is arranged adjacent to it, and a drive mechanism for protruding the 7 oaks is provided at the outgoing end of the conveyance path, so it is the 21st type 3 step. The movable tread is supported by a 7-hole at the horizontal movement point, and as the second tread moves incline, the movable tread rises from the third tread, maintaining the space for the wheelchair and preventing problems (such as transporting a wheelchair user). Since steps with special dimensions for wheelchairs are not provided, the reversal radius of the steps does not increase and only a small main frame is required, making it possible to realize an escalator device that can be easily installed with fewer restrictions on the installation location.

In addition, since an automatic correction means is installed at the entrance to correct the steps, even if the steps do not stop at the correct position, they can be reliably corrected to the correct position.
Moreover, the step can always be stopped at a position where the engagement device can operate, and the operation of the engagement device can also be ensured.
