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 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 sufficient for wheelchairs to get on are pre-installed, and a passenger conveyor start/stop switch for disabled people is provided 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. A person conveyor can be made to stop again with the user's mouth, so that it can be fully used by people with disabilities, or a step structure can be constructed in which the treads can be manually pulled out and spread out over the space, as in Japanese Patent Application Laid-open No. 59-12067. This has been proposed recently.

[Problem that the invention seeks to solve]

However, with the former type of passenger conveyor, even if there is a limited number of steps among the multiple steps, the depth dimension (700 mm) is sufficient for a wheelchair to ride on.
Because the large steps (as described above) are always provided, the radius of the chain gear device for reversing the drive at the entrance and exit must be increased, and the body of the passenger conveyor that accommodates this must inevitably be large. There is a problem in that the installation location is restricted, and in the latter step, an attendant or the escalator manager must always stand by the handicapped person and provide assistance, making it extremely difficult for a handicapped person to safely use the escalator alone. In addition, there is a risk that the wheelchair may come off the treads or fall due to vibrations or sudden stops while the escalator is operating.
There are still many problems that need to be resolved.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a passenger conveyor for disabled persons that does not have the risk of increasing in size and that even one disabled person can use with peace of mind.

[Means for solving problems]

The present invention provides an E
An auxiliary tread plate is provided below the E-shaped tread plate so as to be movable in the front-rear direction, and a rear end of the movable auxiliary tread plate is fitted with the E-shaped tread plate and attached to a normal passenger conveyor. In the passenger conveyor provided with a rotatable inclined plate constituting a tread surface, an upper step adjacent to the step having the movable auxiliary tread plate is configured to be freely inclined.

[Effect]

With the above-described configuration, the wheelchair user can substantially widen the tread of the step simply by giving a command, thereby eliminating the risk of falling while driving.

Next, the operation of the apparatus of the present invention will be explained using the drawings. During normal driving, step 4 for disabled persons is the second
As shown in FIGS. 4a and 3a, the adjacent step 4' also has rollers 9, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 11, 10, 10, 10, 10, 10, 10, 10, 11, 11, 10, 10, 11, 11, 10, 11, 10, 10, 11, 10, 10, 10, 10, 10, 10, 10, 10, and 10, respectively, of the rollers 10, 100 and 10', as shown in FIGS.
90 and 9' are drive levers 30 and 1 near the entrances and exits in the lower and upper parts of the escalator.
30 and 70 (shown in FIGS. 3a and 6a), 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 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 drive levers 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 to the third
In FIG. 6A, the lever 10' rotates about the shaft 11 toward the front of the page, and in FIG. 6A, the lever 10' rotates about the shaft 11' toward the back of the page.

First, this rotational movement of the lever 10 is performed by rotating the pinion 16 counterclockwise around the shaft 15 through the shaft 11, gear 13, gear 14, and shaft 15 as shown in FIGS. 3a and 3b. Then, as shown in FIG. 3b, the auxiliary footboard 5 stored below the footboard 6 is sent out rearward. At this time, the auxiliary footboard 5 is pulled out rearward with the chain 27 wound between the chain gears 25 and 26 meshing with the chain gear 24 (since the roller 90 is restrained by the drive lever 130 (The chain gear 24 is in a fixed state), the chain 27 moves in the direction of the arrow shown in FIG. The state shown in b is reached. Here, the extent to which the treadle 6 is pulled out is determined by the operation of the lever 10, so when a disabled person is using the escalator, the roller 9 is guided by a guide rail or the lever is A locking mechanism is provided at the lever 10 to prevent the lever 10 from rotating while the escalator is in operation. Also, for safety, this inclined plate 1
If the size of 2 is made large enough, even if the auxiliary tread plate 5 is pulled out a little, there will be a hole in the center of the E-shaped tread plate 6. If provided, the auxiliary footboard 5 can be sufficiently pulled out from the footboard 6, and a sufficient base can be secured.

On the other hand, the rotational movement of the lever 10' is shown in FIGS. 6a and 6b by the shaft 11', the bevel gear 43, the bevel gear
Rotate the shaft 45 clockwise through the lever 4
6. Rotate the lever 50 counterclockwise around the shaft 49 via the pin 47a, link 47, pin 47b, lever 48, and shaft 49 to engage the roller 51 and the member 6' to support the footboard 6'. In order to reliably move the foot board 6' downward, the footboard 6' is tilted rearward about the shaft 53 by the hinge 54. According to this tilting motion, the absolute position of the link 55 does not change, so the link mounting plate 57 receives force from the link 55 and rotates counterclockwise together with the shaft 58, and the tooth shaft
9, the gear 62, the shaft 60, and the bracket 61, the riser 42 is folded into the lower part of the step 4', resulting in the state shown in FIG. 6b. Therefore, the above-mentioned two operations, that is, 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, so that the wheelchair as shown in FIG. 7 can be fully seated. Create a space where you can fit in. Here, as can be seen from Fig. 7, the tread plate 6
Although there is a difference in level between the safety plate 33, the inclined plate 12, and the normal step board 6'', a slope is formed at the tip of the inclined plate 12 so that getting on and off the wheelchair is not hindered.

The inclination of the footboard 6' at this adjacent step 4' is determined by the guide rail 7 along which the roller 9' is guided.
2, so the guide rail 7 should have an appropriate shape so that it has a large inclination in the slope section and a slight inclination in the horizontal section.
2 are provided in all sections 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. 110 in the direction of the arrow (shown in Figure 3b). The rotational movement of the lever 100 is caused by the gear 18 through the shaft 110 in FIG. 3b.
In order to rotate the chain clockwise and move the chain 27 in the direction of the arrow in FIG. It rotates approximately 60 degrees counterclockwise around , and stops at the position shown in Figure 3 (c) to act as a wheel stopper. Thereafter, the escalator starts operating in the state shown in FIG. 5, 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 drive lever 130 of the handicapped person's step 4 on the upper floor is moved toward the back of the page by the fourth drive device (corresponding to the second drive device 131) in FIG. 3c. It moves horizontally and rotates the lever 100 in the direction of the arrow via the roller 90 about the shaft 110. The rotation operation of this lever 90 is as follows: shaft 110, gear 18, gear 19, shaft 20, bevel gears 21, 22,
The chain 27 is connected to the third chain via the shaft 23 and the chain gear 24.
By moving it in the direction of the arrow in Figure 3c, the inclined plate 12 is rotated approximately 60 degrees clockwise about the shaft 12a to the state shown in Figure 3b. In this state, a wheelchair can be accessed from a lower floor. Next, after the disabled person gets off the escalator, press the recovery switch S3.
The drive lever 30 of the step 4 for disabled persons on the upper floor and the drive lever 70 of the adjacent step 4' are connected to the fifth and sixth drive devices (first drive device 31 and third drive device) in FIGS. 3b and 6b. Drive device 71
), the levers 10, 10' are horizontally moved toward the back side of the page or the front side of the page, and the levers 10, 10' are rotated about the shafts 11, 11' in the direction of the arrow as the drive lever moves horizontally.

First, this rotational movement of the lever 10 pulls the auxiliary footboard 5 back into the lower interior of the footboard 6 via the shaft 11, gear 13, gear 14, shaft 15, pinion 16, and rack 17. At this time, the auxiliary footboard 5 is retracted with the chain 27 wound between the chain gears 25 and 26 and the restrained chain gear 24 meshing with each other, so the chain 27 moves in the direction of the arrow shown in FIG. 3b. The inclined plate 12 is rotated 180 degrees counterclockwise about the axis 12a to the state shown in FIGS. 2a and 3a, and is reduced to a size no different from that of a normal step.

On the other hand, the rotational movement of the lever 10' is shown in FIG.
Lever 46, pin 47a, link 47, pin 47
b. The lever 50 is rotated clockwise around the shaft 49 via the lever 48 and the shaft 49, and the support position of the treadle 6' is moved upward by the rope 51, so the treadle 6', which remains slightly tilted, is hinged. As the shaft 53 is rotated counterclockwise by the link 54, the link mounting plate 57 receives a force from the link 55 and rotates clockwise together with the shaft 58.
9, the riser 42 appears on the rear step side via the gear 62, the shaft 60, and the bracket 61, as shown in Fig. 4a.
and returns to the normal step state shown in FIG. 6a. Therefore, the two operations described above, namely the retracting movement of the handicapped step 4 and the rotation of the adjacent step 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, the levers 10, 100,
10' are configured so that they can all be rotated in the horizontal direction, but if the lever 80 operates in a vertical plane as shown in FIG.
In addition, as shown in FIG. 9, the riser 42 of the adjacent step 4' is configured to be foldable. This is also because consideration was given to avoid interference with the beam 91.

〔Effect of the invention〕

As explained above, the present invention provides an auxiliary tread plate below the tread plate of at least one step among a plurality of steps of a passenger conveyor, and configures the auxiliary tread plate to be movable in the front and back direction, and to provide an auxiliary tread plate adjacent to the movable step. As for the upper step, the tread is configured to be freely tiltable, and only when a disabled person uses the passenger conveyor, the movable step and the tiltable step are deformed to create enough space for a wheelchair or the like to ride. Not only can one person ride the passenger conveyor safely, 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 of a conventional passenger conveyor. 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 to be foldable into the step, it does not interfere with the beam supporting the guide rail for guiding the step when deformed. It is also possible to use the main frame of the conveyor as it is.
