After raising, by operating the electric motor in the in-process device,
The chain of the work-in-progress device is rotated, and the rotation of the chain is transmitted to the driving force transmission mechanism via the pinion that meshes with the chain, causing the transformation operation from the wheelchair form to the normal form or from the normal form to the wheelchair form. As a result, the time required for the transformation operation is significantly related, and there is a problem that the operating efficiency is poor.

Therefore, in order to improve the operation efficiency,
Japanese Patent Laid-Open No. 3-249093 discloses an escalator device including a wheelchair step.

When the user of the wheelchair disclosed in Japanese Patent Laid-Open No. 3-249093 is transported from the lower end to the upper end of the main frame, first, the work-in-process apparatus is raised by the lifting motor.
Then, with the movement of the wheelchair steps to the rising direction of the decelerated low-speed movement, the work-in-process device and the driving force transmission mechanism pivotally supported by the wheelchair steps are sequentially coupled. Further, as the wheelchair steps move, a fixed meshing member (chain) fixed to the work-in-process device and a movable meshing member (forward sprocket wheel), which is a driving force transmission mechanism, mesh and rotate to rotate Is transmitted, and as a result, the transformation motion is performed from the normal form to the wheelchair form. afterwards,

Then, when the wheelchair-shaped steps for the wheelchair reach the exit of the upper end of the main frame, the in-process device and the driving force transmission mechanism pivotally supported by the steps for the wheelchair are connected. When the work-in-process device and the driving force transmission mechanism are coupled, the fixed meshing member (chain) fixed to the work-in-process device along with the movement of the wheelchair steps and the movable meshing member (reverse sprocket wheel) that is the driving force transmission mechanism
And mesh with each other and rotate in the opposite direction, and the rotational movement is transmitted,
As a result, the transformation motion from the wheelchair form to the normal form is performed.

Next, the operation will be described. First, a case where the special first step 61 transforms into a wheelchair form during the ascending operation will be described with reference to FIG. When the helper or the wheelchair user 7 issues a command to transform the normal mode to the wheelchair mode, the wheelchair step group 6 is switched to the low speed movement. Here, the work-in-process device 8 moves up to a position at which it can be engaged with the driving force transmission mechanism 10 as the lift motor 80 operates. By slowly moving the wheelchair step group 6, by engaging the driving force transmission mechanism 10 of the special first step 61, horizontally projecting first fork 610 is the special second step 62, the normal mode It transforms into a wheelchair form.

More specifically, the position at which the driving force transmission mechanism 10 can be engaged
The chain 85 of the in-process device 8 that has been raised toEspecially1st
The forward rotation pinion sprocket 101 of the step 61 is engaged.
To do. Where specialEspeciallyDriving force transmission mechanism of the first step 61
When engaged with the chain 10, the chain 85 of the work-in-process device 8
It is fixed by the brake mechanism of the stopping motor 83.
Therefore, the forward rotation pinion sprocket engaged with the chain 85
To 101 is specialEspeciallyWith the low speed movement of the first step 61
Rotate clockwise. Forward rotation pinion sprocket 10
The clockwise rotation of 1 is from the pinion shaft 100.gear
(Not shown) via pinion shaft 102 and reverse rotation pinio
It is transmitted to the sprocket 103 and rotates counterclockwise.
, But here the reverse pinion sprocket 10
3 does not work.

The clockwise rotation (driving force) of the normal rotation pinion sprocket 101 is transmitted to the intermediate gear 105 via a gear (not shown), and the intermediate gear 105 rotates counterclockwise around the gear shaft 104. And the counterclockwise rotation causes the pair of first forks 610 engaged with the intermediate gear 105 to horizontally project to the outside rearward through the through holes of the curved rear creep riser. . The protrusion of the first fork 610, the main body 6 of the special second step 62
Moving the step 621 which is supported vertically movable 20, remains elevated (movable footstep 621 special first step 61
(Tread surface parallel to the tread surface) to form a wheelchair form.

[0038] Here, the counterclockwise rotation of the intermediate gear 105, the first fork 610 finishes projects from the special second step 62, a constant torque relative to the gear shaft 104 and the intermediate gear 105 When a certain torque is generated, counterclockwise rotation of the intermediate shaft 104 (driving force for causing the first fork 610 to project) is idly rotated by the overload prevention mechanism 106, and the rotation is caused by the first fork 610.
Then, the transformation operation is performed under proper torque.

The chain 85 of the work-in-process apparatus 8 has guide pulleys 86 attached to the left and right, and is attached to a beam 87 whose central portion is pivotally supported by a shaft 870, and the beam 87 is pivoted around the shaft 870 by a spring 871. Since it operates like a balance, the reverse rotation pinion sprocket 103 of the chain 85 and the driving force transmission mechanism 10 or the normal rotation pinion sprocket 1
It is possible to prevent galling of the roller position of the chain 85 and the teeth of the sprocket when the gears 01 and 01 are engaged and separated. Further, when the chain 85 and the forward rotation pinion sprocket 101 of the driving force transmission mechanism 10 are engaged with the movement of the wheelchair step group 6, the teeth of the forward rotation pinion sprocket 101 contact the guide pulley 86. Without
Since the chain 85 can be directly engaged, the structure for rotating the chain 85 can be simplified, and the driving force of the car stop motor 83 transmitted from the transmission sprocket 84 can be directly transmitted to the driving force transmission mechanism 10. You can also

Further, special-process apparatus of the second step 62 8
Engagement with, as well as the engagement of the special first step 61 described above, the forward pinion sprocket 101 engages the chain 85 and the driving force transmission mechanism 10 of the fixed-process device, obtained The pair of second forks 622 by the driving force
Movable but by projecting horizontally to the outside rearward through the through hole of the rear cleat riser body 620 of the special second step 62, which is supported vertically movable in the body 630 of the special third step 63 the step 631, supported by the elevated left state (a movable footstep 631, the tread and the horizontal tread of special first step 61 and special <br/> second step 62), forming a wheelchair form Therefore, detailed description will be omitted.

Next, with reference to FIG. 6, during the rising operation, describing the transformation operation to the wheelchair form of special third step 63. Chain 85 widget device 8 increased is special <br/> driving force transmission mechanism 10 and the engagement is completed in the second step 62, reverse pinion sprocket 101 of the driving force transmission mechanism 10 of the special third step 63 When engaging with, the vehicle stop motor 83 is driven in advance and the transmission sprocket 84 is rotated counterclockwise, thereby generating a second rotational driving force and rotating the chain 85 counterclockwise.

When the chain 85 and the normal rotation pinion sprocket 101 are engaged with each other, the chain 85 is rotated in the clockwise direction at the same speed as the moving speed of the escalator by the rotation of the car stop motor 83 in advance. In particular, the clockwise rotation of the normal rotation pinion sprocket 101, which is generated by engaging the chain 85 fixed by the brake during low speed operation in the third step 63, does not occur, and the wheelchair does not rotate with respect to the driving force transmission mechanism 10. driving force for transformation operation to the distinct forms due to generated the movement of the use step group 6 is not transmitted, the projection of the wheel stopper 632 is a transformation operation of the special third step 63 is not performed. (See FIG. 6 (A))

Here, even if the driving force in the direction opposite to the direction in which the vehicle stop 632 is projected is transmitted by the rotation of the vehicle stop motor 83, the overload prevention device 106 attached to the intermediate gear shaft 104a is overloaded. the action to release the excessive rotation slipped when the rotation by the winding exceeds a predetermined torque, bollard 632 can be prevented from excessively enters the inside special third step 63. Further, when the chain 85 and the normal rotation pinion sprocket 101 are engaged, the example in which the chain 85 is rotated in the clockwise direction at the same speed as the moving speed of the escalator in advance is shown, but it is not always necessary to rotate at the same speed. There is no such problem, and it is sufficient to rotate in the clockwise direction at a speed at least higher than the moving speed of the escalator. In addition, the brake of the car stop motor 83 is released,
The chain 85 can freely rotate in the forward rotation of the pinion sprocket 101.
It is needless to say that the rotation can be performed by engaging with the same, that is, any method can be used as long as it does not generate the driving force generated by the engagement with the work-in-process device 8 with the movement of the escalator. When the chain 85 can be freely rotated in the clockwise direction by releasing the brake, the car stop motor 83 may have a structure for rotating the chain 85 in the counterclockwise direction. The structure is simple.

After that, when the wheelchair user comes to a predetermined position for riding, the wheelchair step group 6 is stopped, and the wheel stop motor 83 that has been rotating clockwise is stopped.
With this wheelchair step group 6 stopped, the wheelchair user safely gets on the wheelchair step group 6. (See FIG. 6B)

Then, the wheelchair user confirms that the vehicle is safely stopped within the riding position display of the wheelchair step group 6 (a safe position in which the wheel of the wheelchair is not applied to the portion where the car stop is projected), and the wheelchair is driven. By pressing the start button,
With the wheelchair step group 6 stopped, the car stop motor 83 of the work-in-process device 8 starts rotating counterclockwise. The counterclockwise rotation of the wheel stop motor while the wheelchair step group 6 is stopped causes the forward rotation pinion sprocket 101 engaged with the chain 85 to rotate clockwise, and the forward rotation pinion sprocket 101 The rotational driving force of No. 1 rotates the intermediate gear 105a counterclockwise through a sprocket (not shown), and the rotation is transmitted from the intermediate gear 105a to the intermediate gear 105b, and the intermediate gear 105b rotates clockwise. Rotate to. The wheel stop 632 engaged with the intermediate gear 105b is projected by the clockwise rotation of the intermediate gear 195b, and holds the wheelchair so as not to slip. (See FIG. 6C)

When the wheelchair step group 6 is stopped, the escalator is automatically moved up and down after a lapse of time for projecting the car stop 632 (for example, several seconds depending on the performance of the car stop motor 83). To resume. As described above, in the state where the wheelchair step group 6 is stopped, the wheel stop motor 83 causes the wheel stop user to project the car stop 632 only after reaching a predetermined position. Does not project and the lifting operation is resumed after the completion of projecting the car stop 632, so that the safety of the user can be further improved.

During the ascending operation, the transformation operation from the wheelchair form to the normal form at the exit is the same as the conventional one, and the description thereof will be omitted. Further, also during the descending operation, the description is omitted because it is the same as the conventional one.

In the above embodiment, the transformation operation from the normal form to the wheelchair form or from the wheelchair form to the normal form has been described, but it is also possible to perform the transformation motion only by rotating the car stop motor 83. The transformation operation is performed by moving the wheelchair step group 6. For example, a switch or the like for driving the wheel stop motor 83 is provided, and the transformation operation from the wheelchair form to the normal form is forcibly performed even in a stopped state. By generating the third rotational driving force for enabling the transformation operation, the engagement can be disengaged when an abnormality such as an engagement abnormality occurs in the transformation operation, and the efficiency of maintenance work can be improved. It can also be achieved. Further, in the above-described embodiment, the example in which the driving force for projecting the car stop is transmitted by the rotation of the chain has been described. However, with the step stopped, the in-process device main body is moved in the longitudinal direction of the escalator (step advancing direction). It is also possible to generate a driving force for projecting the car stop by moving the vehicle to the vehicle and transmit it to the driving force transmission mechanism.

[0049]

Since the present invention is configured as described above, it has the following effects.

Normal steps arranged in the main frame of the escalator and circulatingly, and interveningly arranged between the normal steps, form a tread similar to the above-mentioned normal steps in the normal form, and form a wheelchair-riding tread and a wheel stop in the wheelchair form. A special step to be formed, a transformation mechanism arranged inside the special step and configured to transform the special step from a normal form to a wheelchair form or from a wheelchair form to a normal form, and a lower floor side entrance / exit vicinity When the car stop is formed, it acts on the transformation mechanism in a state where the circulation movement is stopped, and the car is formed on the special step by the first rotation driving force of the motor included therein. When the wheelchair riding surface is formed, the movement amount of the special step due to the circular movement is converted into a driving force for the transformation operation to form the transformation mechanism. The special steps are equipped with a work-in-progress device for forming a wheelchair-riding tread surface.Therefore, for the transformation until the wheelchair gets into the wheelchair, while maintaining a high carrying capacity by the transformation operation due to the movement of the special steps, When getting in the vehicle, the wheelchair user can be allowed to board the vehicle while the escalator is stopped, and after confirming the safety of the wheelchair user, the car stop can be protruded, which further improves the safety of the wheelchair user for boarding.

Further, since the transformation mechanism has a sprocket and the first rotational driving force of the motor is transmitted to this sprocket, the work-in-process device can be moved only by raising, and the limited installation space inside the main frame is required. In, space saving can be achieved.

Further, the work-in-process apparatus has an engaging member which engages with the transformation mechanism having a sprocket, and the engagement is performed after the wheelchair riding surface of the special step is formed and before the circulating movement for forming the car stop is stopped. In the engaged state of the member and the sprocket, the engaging member rotates in the direction opposite to the rotation direction of the motor that generates the first rotational driving force for forming the car stop, and the sprocket is circulated to move the sprocket. Since the rotation is prevented, the driving force is not generated even when the engaging member and the transformation mechanism are engaged, the transformation operation is not performed, and the escalator can be safely traveled.

Further, the motor is a motor capable of rotating in the forward and reverse directions, and the first rotation driving force for forming the wheel stop and the rotation of the first rotation driving force for preventing the wheel stop formation. Since the second rotational driving force in the direction opposite to the direction is generated, the vehicle stop formation prevention that cancels the driving force generated by the movement amount of the motor and the special step for generating the first rotational driving force is performed. It is not necessary to provide a motor for generating the second rotation driving force, and the structure can be simplified.

Further, the motor is composed of a motor with a brake, and when the wheelchair riding step is formed by the circular movement, the engaging member is fixed by the braking function of the motor with the brake, so that the movement amount of the special step is reduced. Since it is not necessary to newly provide a brake means for fixing the engaging member in order to convert it into the driving force, the structure can be simplified.

Further, the motor is composed of a driving force transmission motor capable of rotating in the forward and reverse directions, and is a first for forming a car stop.
Of the wheelchair and the third rotation driving force for performing the transformation operation from the wheelchair form to the normal form are generated, so that the transformation motion can be forcibly released, and when an abnormality occurs or the like. Maintenance workability is improved.

Further, the engaging member of the work-in-process device is a chain, and the work-in-process device guides the pulley at two left and right sides so as to form a horizontal portion for engaging the sprocket of the transformation mechanism and giving a driving force to the chain. And a transmission sprocket for transmitting the rotational driving force generated by the motor to the chain, and the chain is formed in a ring shape, so that the chain from the motor does not interfere with the sprocket of the transformation mechanism inside the work-in-process device. It is possible to directly guide and rotate the rotation driving force of the device without using a gear or the like, and it is possible to simplify the structure of the in-process device.

Further, the two guide pulleys on the left and right provided to form the horizontal portion on the chain are attached to the same beam, and the beam is a balance mechanism which is pivotally supported about the center so that it can be transformed with the chain. When engaging with the mechanical sprocket, mechanical interference can be reduced, and mechanical noise and tooth galling can be prevented.

Further, since the chain guide is provided on the lower portion of the horizontal portion of the chain formed by the guide pulleys at the two left and right positions, the chain cannot be pushed even if it is pressed by the sprockets of the transformation mechanism. It is possible to guide and reliably transmit the driving force without lowering work efficiency.
