Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in escalators, motorized roads, and other passenger conveyors that are suitable for use by elderly people, handicapped people, and the like.

[Conventional technology]

The depth of current escalator steps is approximately 400 mm, which is sufficient for general passengers to use, but when used by a physically disabled person who uses a wheelchair, etc. The downside was that it was too big to use the escalator.

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 that is deep enough for a wheelchair 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. Recently, a passenger conveyor has been proposed that can be stopped again with the user's mouth and can be easily 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. It is necessary to increase the radius of the chain gear device, etc. for the reversing drive, and the body of the passenger conveyor that houses this inevitably becomes large, which poses a problem in that the installation space 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]

According to the present invention, at least one step out of a plurality of steps constituting a passenger conveyor is configured such that a treadle can be freely pulled out in the front-back direction, and an upper step adjacent to the step that can be freely pulled out is configured to be freely tiltable. .

[Effect]

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

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

During normal operation, the handicapped step 4 is operated by the lever 9, as shown in FIGS. 2a and 3a, and the adjacent step 4' is operated by the lever 9, as shown in FIGS. Since the rollers 8, 38, and 8' provided on the escalators 39 and 9' only contact the switching guide rail 53 near the entrances and exits in the lower and upper escalator sections, the external structure and movement are similar to normal steps. Nothing has changed. 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 S1 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 toward the lower entrance and stops the escalator. Next, when the handicapped step 4 stops at the entrance, the switching guide rail 53 is moved upward by a drive device 60 consisting of a hydraulic device or the like, as shown in FIG. As shown in FIGS. 3 and 10, it rotates clockwise about shafts 10, 10' against the spring pressure of springs 11, 11'.

First, this rotational movement of the lever 9 is shown in FIGS. 3 and 5.
In the figure, shaft 10, gear 21, gear 22, shaft 2

6. Feed out the step board 5 rearward via the rack 37 as shown in FIGS. 3 and 6, and push it back via the link 30 so that the plate 31 closes the hole created by the feed out. At this time, the rack 49 fixed to the chain 48 wound between the chain gears 46 and 47 is engaged with the pinion 45, and the treadle 5
is pulled out rearward, so the chain 48
The inclined plate 13 moves in the direction of the arrow shown in figure a, and the inclined plate 13
Rotate 180 degrees clockwise around point 3a to reach the state shown in FIG. 6a.

On the other hand, the rotational movement of the lever 9' is shown in FIGS.
a, the lever 75 is rotated counterclockwise around the shaft 74 via the link 72, pin 72b, link 73, and shaft 74, and the support position of the footboard 5' by the roller 76 is moved downward, so that the footboard 5' is Hinge 7
9, it is tilted rearward about the axis 78 into the state shown in FIG. 8b. Therefore, the above-mentioned two operations, that is, the pulling out operation of the handicapped step 5 and the tilting operation of the adjacent step 5', are performed in parallel, and the 13th
Create enough space for a wheelchair as shown in the diagram.

The degree of inclination of the treadle 5' of this adjacent step 4' depends on the shape of the guide rail 52 on which the roller 8' is guided, and in the slope section it is inclined to a large degree, and in the horizontal section it is slightly inclined. .

Next, when the wheelchair enters the handicapped person step 4 and presses the handicapped person activation switch S2, the switching guide rail (not shown) on the opposite side shown in FIG. This action causes the lever 39 to rotate clockwise about the shaft 40.
This rotational action of the lever 39 rotates the arm 27' clockwise via the shaft 40 in FIG.
The guide plate 1 is connected to the guide plate 1 via the link 28' (shown in Figure 4).

2. In order to move the chain 48 in the direction of the arrow in FIG. It stops at the position shown in Figure b and acts as a car stop. Thereafter, the escalator starts operating in the state shown in FIG. 9, and when the handicapped step 4 reaches the exit of the upper floor, the escalator is automatically stopped. When the handicapped person's step 4 stops at the exit, the switching guide rail (not shown) on the opposite side of the handicapped person's step 4 on the upper floor is moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and as shown in FIG. The lever 39 is rotated counterclockwise about the shaft 40 via the roller 38. The rotational movement of this lever 39 is caused by a shaft 40,
The opposite guide plate 14' is rotated counterclockwise around a pin (not shown) via the arm 27 and link (not shown), and the shaft 40, gear 41, chain 44, gear 42, shaft 43, The chain 48 is moved through the pinion 45 and the rack 49 in the direction of the arrow in FIG.
Rotate about 60 degrees clockwise about the shaft 13a to bring it to the state shown in Fig. 6a. In this state, a wheelchair can be accessed from a lower floor. Next, after the disabled person gets off the escalator, when he presses the recovery switch S3, the switching guide rail (not shown) in front of the step 4 for disabled people on the upper floor and the switching guide rails (not shown) on both sides of the adjacent step 4' are activated.
is moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and in FIGS. 3 and 4, as the switching guide rail moves downward, the levers 9 and 9' are moved by the spring pressure of springs 11 and 11'. Rotate counterclockwise around 10 and 10'. First, this rotational movement of the lever 9 involves the shaft 10, gear 21,

The treadle 5 is pulled back via the gear 32, chain 35, gear 33, shaft 34, pinion 36, and rack 37. At this time, the rack 49 fixed to the chain 48 wound between the chain gears 46 and 47 is engaged with the pinion 45, and the treadle 5 is retracted, so the chain 48 moves in the opposite direction to the arrow shown in FIG. 3a. The inclined plate 13 rotates 180 degrees counterclockwise around the axis 13a, and becomes the state shown in FIGS. 2a and 3a, and is reduced to a size no different from a normal step. be done.

On the other hand, the rotational movement of the lever 9' is shown in FIGS.
a, the lever 75 is rotated clockwise around the shaft 74 via the link 72, pin 72b, link 73, and shaft 74 to move the support position of the treadle 5' upward by the roller 76, leaving a slight inclination. The footboard 5' is rotated counterclockwise about the shaft 78 by the hinge 79 and returns to the horizontal state shown in FIG. 8a. Therefore, the above-mentioned two movements, namely the retraction movement of the handicapped step 5 and the adjacent step 5'
The rotational movement of the escalator is carried out in parallel, and the escalator is restored to the same state as a normal escalator.

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 an upper floor.

〔Effect of the invention〕

As explained above, the present invention is such that the tread plate of at least one of the plurality of steps of the passenger conveyor can be freely pulled out in the front and back direction, and the tread plate of the upper step adjacent to the step that can be freely pulled out can be freely tilted. When a disabled person uses the passenger conveyor, the retractable steps and tiltable steps are deformed to create enough space for a wheelchair, etc., so even a disabled person can safely use the passenger conveyor alone. Not only can you ride on it, but the steps are usually exactly the same size as a general passenger conveyor, so the sprocket for reversing the steps can be the same size as the sprocket on a conventional passenger conveyor, which inadvertently reduces the overall size of the passenger conveyor. It never gets bigger.
