Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in passenger conveyors such as escalators, motorized roads, etc., which are suitable for use not only by the general public but also by the elderly and the disabled.・[Problems to be solved by the prior art and the invention] The depth dimension of current escalator steps is approximately 400 mm, which is sufficient for general passengers to use, but it is not suitable for wheelchair users. When used by a person with a physical disability, the wheelchair is too large and cannot be used on an escalator.

On the other hand, when a person with a disability etc. gets on an escalator,
In particular, in the case of a wheelchair, it is necessary to stop the escalator once, and it is also necessary to stop the escalator once to get off the escalator, and to get on and off safely.

For this reason, one or more large steps with a depth sufficient for wheelchairs to get on are installed in advance, and a passenger conveyor start/stop switch for disabled people is installed at the entrance. The operation ensures that this large step stops at the boarding entrance, and after a wheelchair passenger gets on board, the passenger conveyor is activated by pressing a dedicated start switch, and after a certain period of time, the large step is stopped at the destination floor. Try to stop it again with your mouth,
Recently, passenger conveyors that can be used by people with disabilities have been proposed.

However, with such passenger conveyors, even if there is a limited number of steps among the multiple steps, there is always a large step with a depth dimension (more than 700 cranes) that a wheelchair can ride on, so the entrance The radius of the chain gear device, etc. for reversing drive, which is reversed at the part, must be increased.
There was a problem in that the body of the passenger conveyor that accommodated this was inevitably large, which restricted the installation space.

Furthermore, as in Japanese Patent Application Laid-open No. 59-7685, a device has also been proposed in which a lifting mechanism is separately provided to push up the tread of a certain step to the position of the tread of an adjacent upper step, thereby substantially expanding the area of the tread. However, when a large wheelchair such as one for an adult rides toward the top of the passenger conveyor, the foot rest of the wheelchair hits the riser of the upper step, so it is not always possible to ride the passenger conveyor in a forward-facing position. Not only is it inconvenient to use, but since there is no wheel stopper, there is a high risk of wheels falling off or falling due to vibrations during operation of the passenger conveyor, making it impossible for a disabled person to use the passenger conveyor alone. Furthermore, even when only the person in -C is using this passenger conveyor, the mechanism that pushes up the treadle is activated, so when a passenger steps up from below, there is a risk of tripping on the protruding treadle and causing injury. It is also dangerous.

The present invention has been made in view of the above points, and an object thereof is to provide a passenger conveyor that can secure enough space for the treads even for large wheelchairs and can be used safely by both disabled people and the general public.

[Means for solving problems]

According to the present invention, the treads of any two adjacent steps of a plurality of steps constituting a passenger conveyor are configured to be movable in the vertical direction with respect to each of the steps, and the step of the upper step of the two steps is configured to The lower step of the two steps is provided with a first elevating and lowering mechanism for moving the tread of the upper step to a position where there is no step difference of more than a predetermined distance from the M plate of the upper step adjacent to the upper step. In a passenger conveyor equipped with a second elevating movement mechanism that moves the tread of the lower step so as to maintain the same height position as the tread of the upper step, the rear end of the tread of the lower step is sloped. The plate is rotatably provided, and the inclined plate is rotated by a rotational drive mechanism based on a command.

[Effect]

With the above-described configuration, when a wheelchair user uses a passenger conveyor, a space for the treads can be secured without fear of falling, even if the wheelchair user is a large wheelchair.

Similarly, switching guide rails and drive devices are provided in the upper layer as well.

Next, the operation of the apparatus of the present invention will be explained using the drawings.

During normal operation, the lower step 4 for disabled persons is as shown in Figure 2 (
As shown in FIGS. 3(a) and 4(a), the upper handicapped step 4'' is provided on the levers 10, 20 and 10', as shown in FIGS. 3(a) and 4(a). Since the rolled rollers 9, 19 and 9' only contact the switching guide rails 39 and 40 near the entrances and exits in the lower and upper parts of the escalator, the external structure and movement are no different from normal steps. Here, when a disabled person in a wheelchair comes to the boarding entrance on the lower floor shown in Fig. 1 and presses the stop switch Sl for disabled people, the protrusion provided only on the lower step 4 for disabled people, for example, is activated by the limit switch. A well-known detection mechanism detects when the lower handicapped step 4 rotates toward the lower entrance and stops the escalator.

Next, when the handicapped step 4 stops at the entrance, the switching guide rails 39 and 40 are moved by the drive devices 41 and 42, which are hydraulic devices, etc., as shown in FIGS. 4(a) to 4(b). This movement causes the lever 10.
10' resists the spring pressure of spring 43.43' and pin 1). 1) Rotate clockwise around '' and press lever 10.
．． The rollers 9, 9' provided at the guide rail 4

Next, when the wheelchair enters the handicapped step 4.4' and presses the handicapped start switch S2, the switching guide rail (not shown) provided near the switching guide rail 39 of the lower handicapped step 4 is activated. is moved upwardly by a drive device (not shown) comprising a similar hydraulic device or the like, and this operation causes the lever 20 to rotate clockwise about the pin 21. This rotational movement of the lever 20 is caused by the chain gear 22 in FIG. 4(a) (see FIG. 4(C) for details).
The pin 28a is rotated clockwise through the chains 23, 25, 27 wrapped around the chain gears 24.24', 26.26'', 28, and the gears 28' and 28' fixed to the pin 28a. The shaft 12a is rotated counterclockwise via the gear 30.pin 16b, chain gear 29.chain 31.chain gear 32, and the inclined plate 12 fixed to the shaft 12a is rotated to the fourth position.
It is stopped at the position shown in Figure (b) to act as a car stop.

After that, the escalator starts operating and the guide rail 44
In response to changes in the inclination angle of the levers 10.10', the levers 10.10' rotate clockwise (counterclockwise near the upper exit), and in response to this rotation, the rollers 33.36 move the levers 10.10. Notch portion 10a, 1 provided at 10”
0'a and the position changes, this change is transmitted through the link mechanism to the treads 5, 5 of the steps 4, 4' for the disabled.
In the slope section, as shown in Figure 1, the height difference between the tread 5' of the upper step 4' for the disabled and the tread of the step 3 above it is greater than a predetermined value (for example, the footrest of a wheelchair). As shown in Figures 1 and 4 (C1), raise the treads 5 of the lower step 4 for the disabled to prevent them from widening. Raise it to keep it at the same height as 5'.

Next, when the handicapped step 4.4' reaches the exit of the upper floor, the escalator is automatically stopped, but when the handicapped step 4, 4' stops at the exit, the lever 20 switches the guide rail on the upper floor. is moved downward by a drive device such as a hydraulic device, and in FIG. 4(b), the roller 1
9, the lever 20 is rotated counterclockwise about the pin 21. The rotational movement of this lever 20 is caused by the chain gear 2
2° 24.24', 26.26', 28 and the chain 23, 25, 27 wrapped around these chain gears to rotate the pin 28a counterclockwise, and the gear 28 fixed to the pin 28a. ' and gear 30° pin 16b, 1N gear 2
9. Chain 31. The shaft 12a is rotated clockwise via the chain gear 32, and the inclined plate 12 fixed to the shaft 12a is returned to the state shown in FIG. ) Next, after the disabled person gets off the escalator, when the recovery switch S3 is pressed, the switching guide rails (not shown) of the upper and lower steps 4' and 4 for disabled people on the upper floor ) is moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and the lever 10.10' in FIG.
As the switching guide rail moves downward, the pin 1). 1) Rotate counterclockwise around '' and return to the state shown in FIG. 4(a), which is no different from the normal step.

In the above description, a case has been described in which a handicapped person gets on an escalator from a lower floor and gets off at an upper floor. However, the present invention can be carried out essentially the same even when a person gets off at a lower floor.

〔Effect of the invention〕

As described above, according to the present invention, only when a disabled person uses a passenger conveyor, the step between the treads of two adjacent steps of a plurality of steps of the passenger conveyor and the step above is prevented from exceeding a predetermined distance. Since the steps are moved vertically at the same height, there is not only enough space for even large wheelchairs to ride forward, but also because the steps are usually the same size as a general passenger conveyor, so the steps can be reversed. The sprocket to be used is the same size as the sprocket of a conventional passenger conveyor.
The overall size of the passenger conveyor will not increase unnecessarily. Furthermore, since the inclined plate provided at the rear end of the tread of the lower step can be changed to an upright position for stopping the vehicle, even a single disabled person can use the passenger conveyor extremely safely.
