Each of the steps 4 and 5 is provided with a gear mechanism (not shown) including a first sprocket 9. By rotating the sprocket 9, a coupling tool (not shown) is driven to respectively lower the step board 5 </ b> F by one step. , 6F. As described above, the lower treads 5F, 6
By connecting F, when the step 4 moves to the inclined portion of the escalator device, the treads 5F and 6F of the steps 5 and 6 are scooped up and maintain the same position as the tread 4F of the step 4 and the wheelchair 8 is moved. A horizontal surface that can be mounted is formed. A first sprocket 10 similar to step 6
Is provided. This sprocket 1
The gears 11 and 12 mesh with 0, and the rack 14 of the wheel stopper 13 meshes with the final gear 12.

The first sprocket 9 of the steps 4, 5 has a second sprocket (not shown) coaxially with a reversing gear, and the first sprocket 1 of the step 6
Reference numeral 0 also has a second sprocket (not shown) in which a reverse gear is coaxially interposed.

The step group 3 having the above-described configuration includes the guide rails 15A and 15A fixed to the main frame 1 together with the normal step 2.
Drive along 5B.

On the other hand, as shown in FIG. 5, a power transmission device for rotating the first sprockets 9, 10 and the second sprocket is provided on the main frame 1 facing the upper and lower floors of the entrance and exit sections. 16A, 16B (16B1, 16B2) are provided. These power transmission devices 16A, 16B, 16B
As shown in FIG. 5, the power transmission devices 16A1 and 16B2 are arranged side by side on the lower floor, and the power transmission devices 16B1 and 16B2 are arranged side by side on the upper floor.

When the first sprockets 9, 10 of the steps 4, 5, 6 of the specific step group 3 engage with the power transmission device 16A on the lower floor during the ascending operation, the first sprockets on the upper floor, respectively. The second sprocket, which is coaxial with the sprockets 9 and 10 of the second gear, is disposed so as to mesh with the power transmission device 16B2,
Also, during the descent operation, each first sprocket 9,
The second sprocket, which is coaxial with each of the first sprockets 9 and 10, and the power transmission device 16B are arranged on the lower floor side so as to mesh with each other.

The power transmission devices 16A, 16B and 16
B1 and 16B2 are configured as shown in FIG. First, the power transmission device 16A rotatably supports a movable frame 19 on a mounting frame 17 for mounting on the main frame 1 via rotating arms 18A and 18B. On the top of this movable frame 19,
Two sprockets 20A and 20B are pivotally supported.
These two sprockets 20A and 20B are provided in parallel with the tread of the step and at intervals along the depth direction of the step. The drive sprocket 21 is supported between the sprockets 20A and 20B at a lower position than the sprockets. An endless rotating chain 22, which is a movable rack or a movable chain, is wound around and engaged with the sprockets 20A and 20B and the driving sprocket 21. An electric motor 23 drives the drive sprocket 21 directly or indirectly. Reference numeral 24 denotes a lower portion of the chain 22 so that the chain 22 stretched horizontally between the two sprockets 20A and 20B is not bent by a predetermined value or more by engagement with the first sprockets 9, 10 and the second sprocket. It is a displacement regulating body provided with a minute gap G1 on the side.

The movable frame 19 having the above structure is connected to a rocker 26 fixed to the mounting frame 17 via a link mechanism 25. In the wheelchair transport operation, the rocker 26 is configured to be driven by detecting that the step 4 approaches when ascending, and to be driven to detect when the step 6 approaches when descending.

On the other hand, the power transmission devices 16B, 16B1, 1
6B2 is a chain 27 that is horizontally held at the same height as the chain 22 stretched horizontally between the sprockets 20A and 20B, and is connected to both ends of the chain 27 and is similar to the rotating arms 18A and 18B. Rotating arm (not shown)
And the tension adjusting devices 30A and 30B pivotally supported by.

Next, the normal ascending operation of the escalator device having the above-described configuration will be described. First, when operating as a general escalator device, the power transmission device 16
A, 16B, 16B1, and 16B2 are supported at lower positions as shown by the two-dot chain lines in FIG. Therefore, the chains 22, 27 are connected to the first sprockets 9, 1 respectively.
It is retracted to a position where it does not interfere with the 0th and second sprockets. By performing a normal ascent operation in this state, each of the steps 4 to 6 of the step group 3 travels along the guide rails 15A and 15B in the same manner as the normal step 2, and can carry ordinary passengers. If a wheelchair transport command is issued by, for example, a button operation of an attendant during the normal driving, the entry of general passengers is prohibited, and the driving of the passengers already on the vehicle is continued until they reach the exit. And the specific step group 3
Immediately before the step 4 appears from the lower floor LF, the rocker 26 of the power transmission device 16A is driven to raise the movable frame 19. As the movable frame 19 rises, the steps 4, 5 of the specific step group 3 continue to move while engaging the first sprocket 9 with the chain 22, and the steps 4 to 6 of the specific step group 3 are completely removed from the lower floor landing floor LF. The movement of the step stops at the position where it appears. Steps 4 and 5 of specific step group 3 are moving chains 2
Due to the rotation of the first sprocket 9 due to the engagement with the second gear 2, a connecting tool (not shown) is driven to couple the steps 5F and 6F between the steps 5F and 6F of the steps 5 and 6 one step below. At this time, the first sprocket 10 of the step 6 has started to mesh with the end of the chain 22.

As described above, when the specific step group 3 stops at the position that emerges from the lower floor LF, the wheelchair 8 is put on the specific step group 3 as shown in FIG.

When the ride in the wheelchair 8 is completed, the attendant presses the start button. By operating the start button, the electric motor 23 starts to rotate the chain 22 in the direction of the arrow in FIG. By the rotation of the chain 22, the first sprocket 10 and the speed increasing gears 11 and 12 in the step 6 are rotated, and the wheel stopper 13 is finally projected from the tread surface via the rack 14 (two points in FIG. 1). Chain line).

When it is detected by a detector or the like that the bumper 13 has protruded by a predetermined size, the escalator device starts operating and moves the steps.

When driving is started, general passengers can enter, and the transport of the wheelchair 8 and the general passengers are carried at the same time. When the step 4 of the specific step group 3 enters the inclined portion, the step 5F of the step 5 connected to the step 4 as shown in FIG.
And the tread 6F of the step 6 connected to the tread 5F of the step 5 keeps the same position as the tread 4F of the step 4, so that the three treads are horizontally arranged to form a wheelchair mounting surface.

The specific step group 3 equipped with the wheelchair 8 is shown in FIG.
As shown in (C), when approaching the upper floor UF, the attendant pushes the wheelchair 8 to the upper floor UF and lowers the wheelchair 8 from the escalator device.

At this time, since the steps 2 including the specific step group 3 continue to move without stopping, the specific step group 3
When the vehicle approaches the upper floor UF, the power transmission device 16B2 installed on the upper floor side is raised and the chain 27
Is meshed with a second sprocket (not shown) having a reverse gear coaxial with the first sprockets 9 and 10 of the steps 4 to 6, and is rotated by the relative movement of the two. By the rotation of the second sprocket, the connection between the treads 4F and 5F and the connection between the treads 5F and 6F are released, and the wheel stop 13 is also returned to the home position.

As described above, since the connection of the treads and the pull-back of the wheel stop 13 are performed during the movement of the steps, it is possible to return to the normal operation without stopping the movement of the steps.

The above description is for the ascending operation. Next, the descending operation will be described. When a wheelchair transport command is issued by a button operation of a clerk during a normal descent operation, the rocker 26 of the power transmission device 16B1 is driven and movable immediately before the steps 4 of the specific step group 3 appear from the upper floor UF. The frame 19 is raised, and the chain 27 and the first sprockets 9 and 10 are engaged with each other, so that the first sprockets 9 and 1 are engaged.
By rotating 0, the vehicle stop 13 is made to protrude, then the connection between the treads 6F, 5F and the connection between the treads 5F, 4F are performed, and the step group 3 is stopped at the position shown in FIG. . Here, when the driving is resumed by getting on the wheelchair 8, the specific step group 3 is moved to the state shown in FIG.
(A).

The second sprocket meshes with the chain 27 one after another by raising the movable frame 19 of the power transmission device 16B on the lower floor immediately before the specific step group 3 reaches FIG. And the connection between the treads is released. Since the stop 13 is pulled back, when the specific step group 3 reaches the position shown in FIG. 5A, the attendant pushes the wheelchair 8 up and down to the lower floor LF without stopping the movement of the steps 2 and 3.

As described above, during a wheelchair transport and ascending operation, the vehicle stop is transmitted and protruded at the entrance side by transmitting the power of the driving device, and pulled back at the exit side by using the relative moving force between the step and the fixed portion. In addition, during wheelchair transport lowering operation, the car stop is made to protrude using the relative moving force between the step and the fixed part at the entrance side and the exit side, so after the car stop completely comes out at the entrance side Equipped with a wheelchair carrier, the wheelchair can be lowered at the exit side without stopping the movement of the steps.

Meanwhile, in the power transmission device 16A, as shown in FIG. 1, a displacement regulating body 24 is provided with a gap G1 under a chain 22 stretched horizontally between two sprockets 20A and 20B. When the chain 22 is turned and meshed with the sprocket 10 of the step 6, as shown in FIG.
If 0 is engaged, the displacement of the chain 22 is small, and the chain 22 smoothly rotates without contacting the displacement regulating body 24 due to the gap G1. On the other hand, when the chain 22 is engaged with the sprocket 9 without rotating, the chain 22 is given a constant tension T, but when the tangential component force F1 comes out of the sprocket 9 at the time of engagement, As shown in FIG.
The chain roller 22 </ b> R of the chain 22 is pushed downward, and the engagement with the sprocket 9 is made incomplete. This will be described in detail with reference to FIGS. 3 and 4.
As shown in (1), there is a certain gap G1 between the chain 22 and the displacement regulating body 24, and the meshing portion of the chain roller 22R is in a floating state. However, as the engagement progresses,
Since the chain roller 22R receives the component force F1 from the sprocket 9, when the component force F1 increases, the chain roller 22R is pushed down by the sprocket 9, as shown in FIG. The chain 22 is pushed down and the gap G
1 is gone, the chain 22 is
Of the chain roller 22R
And the sprocket 9 are no longer disengaged.

Although the above-described embodiment uses a series of chains 22, a plurality of chains may be used as shown in FIG. FIG. 6 shows a triple chain 22A, 22B, 2
2C, each of which is connected by a connecting pin 29. And the chains 22A on both sides of the chain 22B,
22C is a double drive sprocket 20RA, 20RB, 2
1R, so that the sprockets 9 and 10 of the step group 3 mesh with the central chain 22B. Needless to say, the displacement of the chain 22B with which the sprockets 9 and 10 mesh is performed by providing the displacement regulating bodies 30A and 30C on the movable frame 19 facing the chains 22A and 22C.

By using the triple chains 22A, 22B and 22C, the passage positions of the step side sprockets 9 and 10 and the installation positions of the two double sprockets 20RA and 20RB can be set at different positions. 9, 10 and double sprocket 20RA, 20RB
There is no interference between the teeth of the sprocket and the chain, and the engagement between each sprocket and the chain can be deepened.

In the above-described embodiment, the example in which the sprockets 9, 10 of the step group 3 are rotated by the same chains 22, 22B to connect the tread plates and to project the bogie stops has been described. A dedicated chain facing each of the 10 and the second sprocket may be provided to perform connection and release between the treads and to project the wheel stop 13.

Further, a power transmission device 1
6A and one power transmission device 16B on the upper floor
And the first sprockets 9 and 10
The power transmission devices 16A and 16B may be configured to move in parallel so as to face the second sprocket.

Further, as shown in FIGS. 7 to 9, one power transmission device 16A is arranged on the lower floor side of the getting on / off section so as to face the first sprockets 9 and 10, and on the upper floor side of the getting on / off section. The power transmission device 16B may be arranged to face the second sprockets 31, 32 with one reversing gear 31R, 32R interposed. The operation in the case where one power transmission device is installed in each of the entry and exit sections on the upper and lower floors will be described.

First, at the time of ascending operation, as shown in FIG. 8, the first sprocket 9 is successively engaged with the rotating chain 22 of the power transmission device 16A and rotates in the direction of arrow a in the lower floor getting on / off section. Then, the connecting piece 33 of the adjacent tread is moved to the arrow Ra.
In the direction, and the movement of the step is stopped at a position where the first sprocket 10 starts to mesh with the rotating chain 22.
In this state, when the user turns on the wheelchair and presses the start button, the rotation chain 22 moves in the direction of arrow c, rotates the first sprocket 10 in the direction of arrow a, and stops the wheelchair 13.
Is moved in the direction of arrow U. In this state, when the vehicle starts moving and comes to the getting-on / off section on the upper floor side, the second sprockets 31, 32 are sequentially engaged with the fixed chain 27 of the power transmission device 16B, and the reversing gears 31R, 32R are moved in the direction of arrow b. Rotate
The connecting piece 33 is moved in the direction of the arrow Rb to return to the original position, and the wheel stopper 13 is moved in the direction of the arrow D and retracted.

Next, at the time of the descending operation, as shown in FIG. 9, the second sprocket 32 is engaged with the fixed chain 27 of the power transmission device 16B in the upper floor getting on / off section, and the reverse gear 32R is moved in the direction of arrow a. , And turn the bollard 13 to the arrow U
Move in the direction. In this state, when the movement of the steps is stopped and the wheelchair is put on, and the start button is pressed, the second sprockets 31 are successively engaged with the fixed chain 27, and the reverse gear 31R is rotated in the direction of arrow a so as to be adjacent thereto. The connecting piece 33 of the tread is moved in the direction of the arrow Ra to connect the adjacent treads, and starts to move. When you move to the lower floor getting on and off,
The first sprockets 10 and 9 sequentially mesh with the rotating chain 22 that has stopped rotating, rotate in the direction of arrow b, move the stop 13 in the direction of arrow D, and move the connecting piece 33 in the direction of arrow. Move in the Rb direction to return to the original position. By arranging the power transmission devices 16A and 16B in this way, the number of power transmission devices and their attached devices can be minimized, and the configuration can be simplified.
