Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to improvement of passenger conveyors such as escalators and motorized roads suitable for use not only by general passengers but also by disabled people using wheelchairs etc. It is.

[Conventional technology]

The depth of the current escalator steps is approximately 400 mm.
This size is sufficient for general passengers to use, but when used by a physically disabled person who uses a wheelchair, there is a drawback that the wheelchair is too large and the escalator cannot be used. Ta.

On the other hand, when a disabled person or the like gets on an escalator, especially in a wheelchair, it is necessary to stop the escalator once, and when getting off the escalator, it is also necessary to stop the escalator and get on and off safely.

For this reason, one or more large steps with a depth sufficient to accommodate a wheelchair are installed in advance.
In addition, a passenger conveyor start/stop switch for disabled people is installed at the entrance, and when the stop switch is operated, this large step always stops at the entrance, and a special start switch is installed after a wheelchair passenger gets on board. Recently, a passenger conveyor has been proposed in which the passenger conveyor is activated by pressing , and after a certain period of time, the large step is stopped again at the exit of the destination floor, so that it can be fully used by people with disabilities.

[Problem that the invention seeks to solve]

However, such passenger conveyors are always equipped with large steps with a depth (700 mm or more) that is deep enough for a wheelchair to ride on, even if the number of steps is limited among the multiple steps. The radius of the chain gear device, etc. for the reversing drive must be increased, and the body of the passenger conveyor that accommodates this must inevitably become large, which poses a problem in that the installation location is restricted.

The present invention has been made in view of the above points, and an object of the present invention is to provide a passenger conveyor that does not have the risk of increasing in size.

[Means for solving problems]

The present invention provides an auxiliary tread that is movable in the front-rear direction below the tread of at least one step among a plurality of steps constituting a passenger conveyor, and an upper step adjacent to the step having the movable auxiliary tread. is configured to be freely tiltable, and the riser of the adjacent upper step is configured to be freely foldable.

[Function] If configured as described above, the footboard can be substantially widened only when used by a wheelchair user.

The external structure and movement are no different from normal steps. Here, when a disabled person in a wheelchair comes to the entrance of the lower floor shown in Fig. 1 and presses the stop switch Sl for disabled persons, the limit switch detects, for example, a protrusion provided only on step 4 for disabled persons. A well-known detection mechanism detects when the handicapped step 4 rotates to the lower entrance and stops the escalator.Next, when the handicapped step 4 stops at the entrance, the drive lever is activated. 30 and 70 are horizontally moved by the first drive device 31 and the third drive device 71, and this operation causes the lever 10 to move horizontally.
The lever 10' rotates toward the front of the page about the shaft 11 in FIG.
Rotate towards the back of the page with ′ as the center.

First, this rotational movement of the lever 10 is shown in FIGS. 3(a) and (

In order to reliably move the support position downward, the treadle 6' is tilted rearward about the shaft 53 by the hinge 54.Following this tilting movement, the absolute position of the link 55 does not change, so the link is attached by the link 55. Plate 57 receives the force and rotates counterclockwise together with shaft 58, causing gear 59. Gear 62. Axis 60. The riser 42 is folded into the lower part of the step 4' via the bracket 61, resulting in the state shown in FIG. 6(b). Therefore, the above-mentioned two operations, namely, the movement of pulling out the handicapped step 4, the tilting movement of the adjacent step 4', and the folding movement of the riser 42 are performed in parallel, and there is enough space for a wheelchair as shown in FIG. create. Here, as can be seen from FIG. 7, there are steps between the tread plate 6 and the safety plate 33, and between the inclined plate 12 and the normal step tread plate 6#, but by forming a slope at the tip of the inclined plate 12, the wheelchair This is done so that there will be no difficulty in getting on and off the train.

Note that the degree of inclination of the treadle 6' in this adjacent step 4' depends on the shape of the guide rail 72 on which the roller 9' is guided, so the degree of inclination is the largest in the slope section, and the degree of inclination is slightly in the horizontal section. Guide rails 72 of a suitable shape are provided over the entire running section of the escalator.

Next, when the wheelchair gets on the step 4 for disabled people and presses the activation switch S2 for disabled people, the drive lever 130 shown in FIG. The lever 100 rotates in the direction of the arrow (shown in FIG. 3(b)) about a shaft 110.

The riser 42 appears on the rear step side via the bracket 61 and returns to the normal step state shown in FIG. 4(a) and FIG. The pulling movement operation and the rotation operation of the adjacent step/p 4' are performed in parallel, and the escalator is restored to the same state as a normal escalator.

In the above explanation, 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 implemented without any essentially changes even when a person with a disability gets on an escalator from an upper floor and gets off at a lower floor.

In the above embodiment, all the levers 10, 100° 10' are configured to be able to rotate in the horizontal direction, but this is not possible in the case where the lever 80 operates in a vertical plane as shown in FIG. may interfere with the beam 91 supporting the guide rail 90 that guides the front wheel 7 or rear wheel 8 of the step 4, and as shown in FIG. The reason for this configuration is to prevent interference with the beam 91.

〔Effect of the invention〕

As explained above, the present invention provides an auxiliary tread below the tread of one step of a plurality of steps of a passenger conveyor, and has a simple configuration in which this auxiliary tread can be freely pulled out in the front and back direction. For the upper step adjacent to the step, the tread is configured to be tiltable,
Only when a handicapped person uses the passenger conveyor, the retractable steps and tiltable stitching are transformed to create enough space for a wheelchair, etc., so even a handicapped person can not only ride the passenger conveyor safely alone, but also Normally, the steps are exactly the same size as a general passenger conveyor, so the sprocket that reverses the step needs to be the same size as the sprocket of a conventional passenger conveyor, and the overall size of the passenger conveyor will not increase unnecessarily. .

Furthermore, since the riser of the tiltable step of the present invention is configured so that it can be folded into the step, it does not interfere with the beam supporting the step guide guide rail when deformed. The main frame of the conveyor can be used as is.
