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, 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 the case of 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 exclusively for the disabled is activated. A stop switch is installed at the entrance, and when the stop switch is operated, the large step is always stopped at the entrance, and after a wheelchair passenger gets on board, the passenger conveyor is started by pressing a dedicated start switch. Recently, a passenger conveyor has been proposed in which the large step is stopped again after a certain period of time, that is, 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 get on, even if only a limited number of the steps are available. 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 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 includes an auxiliary tread built into the lower part of the tread of any step that can be freely pulled out in the depth direction, and an upper step adjacent to the step that can be freely pulled out. To provide a small-sized passenger conveyor which is configured to be freely tiltable, has a substantially wide tread plate only when used by a handicapped person, and can be sufficiently ridden by a wheelchair.

A drive lever 70 is driven horizontally by a third drive device 71 and engages with a roller 9' to operate a lever 10', and a drive lever 72 is used to drive the rear wheels 8, 8' and 8' when operating the escalator with a disabled person on board. This is a guide rail that guides the roller 9'.

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 of all, this rotational movement of the lever 10 is shown in FIGS. 3a and 3b.
The pinion 16 is rotated counterclockwise around the shaft 15 through the rack 17, and the auxiliary footboard 5 is housed below the footboard 6 as shown in FIG. 3b.
send out backwards. At this time, chain gears 25 and 26
Chain 27 and chain gear 2 wrapped between
4 is engaged, the auxiliary footboard 5 is pulled out rearward (the roller 90 is restrained by the drive lever 130, so the chain gear 24 is in a fixed state), so the chain 27 is moved as shown in FIG. 3a. Moving in the direction of the arrow, the two inclined plates 12 are rotated 180 degrees clockwise about the shaft 12a, resulting in the state shown in FIG. 3b. 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. In addition, if the size of the inclined plate 12 is made sufficiently large for safety, even if the auxiliary tread plate 5 is pulled out a little, a hole will be made in the center of the tread plate 6, which is configured in an E shape, but the rear end of the tread plate 6 By providing the safety plate 33 on the back side of the section, the auxiliary footboard 5 can be sufficiently pulled out from the footboard 6, and sufficient space can be secured.

On the other hand, the rotation operation of the lever 10' rotates the shaft 45 clockwise via the shaft 11', the bevel gear 43, and the bevel gear 44 in FIGS.
6. Rotate the lever 50 counterclockwise around the shaft 49 via the pin 47a, link 47, pin 47b, lever 48, and shaft 49 to support the footboard 6' by engaging the roller 51 and the member 6'a. In order to reliably move the position downward, the footboard 6' is tilted rearward about the shaft 53 by the hinge 54. According to this tilting movement, the link mounting plate 5 is moved by the link 55.
7 receives the force and rotates counterclockwise together with the shaft 58, and the gear 59, the gear 62, the shaft 60, and the bracket 6
1, the riser 42 is folded under the step 4' into the position shown in FIG. 6b. Therefore, the aforementioned two operations, namely, the pulling out operation of the handicapped step 4, the tilting operation of the adjacent step 4', and the folding operation of the riser 42 are performed in parallel.
Create enough space for a wheelchair as shown in Figure 7. As can be seen from FIG. 7, there are steps between the tread 6 and the safety plate 33, as well as the inclined plate 12 and the normal step tread 6'', but by forming a slope at the tip of the inclined plate 12, the wheelchair It is designed so that there is no problem with heavy rain.

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). This rotational movement of the lever 100 rotates the gear 18 clockwise via the shaft 110 having the universal joint 110a in FIG.
3. Chain 27 via chain gear 24 in Figure 3b
In order to move the wheelchair in the direction of the arrow, the inclined plate 12 rotates about 60 degrees counterclockwise about the shaft 12a and stops at the position shown in FIG. 3c to prevent the wheelchair from slipping off. 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 Step 4 for disabled people stops at the exit,
In FIG. 3c, the drive lever 130 of the step 4 for disabled persons on the upper floor is horizontally moved toward the back of the paper by the fourth drive device (corresponding to the second drive device 131), and the lever 10 is moved via the roller 90.
0 around the axis 110 in the direction of the arrow. The rotational movement of this lever 90 includes a shaft 110, a gear 18,
Gear 19, shaft 20, bevel gears 21, 22, shaft 23,
The chain 27 is moved in the direction of the arrow in FIG. 3c via the chain gear 24, and the inclined plate 12 is rotated approximately 60 degrees clockwise about the shaft 12a to the state shown in FIG. 3b. In this state, a wheelchair can be accessed from a lower floor. Next, when the disabled person presses the recovery switch S3 after getting off the escalator, the drive lever 30 of the step 4 for disabled people on the upper floor and the drive lever 70 of the adjacent step 4' are moved as shown in FIG. 3b.
In FIG. 6b, the levers 10, 10' are horizontally moved toward the back side of the page or the front side of the page by the fifth and sixth drive devices (corresponding to the first drive device 31 and the third drive device 71). As the drive lever moves horizontally, it rotates about the shafts 11, 11' in the direction of the arrow.

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 around the shaft 12a to be in the state shown in FIGS. 2a and 3a, and is reduced in size to the same size as 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 tread plate 6' is moved upward by the roller 51, so the tread plate 6', which remains slightly tilted, is hinged. As the gear 54 rotates counterclockwise around the shaft 53, the link mounting plate 57 receives force from the link 55 and rotates clockwise together with the shaft 58.
9, the riser 42 is exposed to the rear step side via the gear 62, shaft 60, and bracket 61, returning to the normal step state shown in FIGS. 4a and 6a. Therefore, the two operations described above, namely the retracting operation of the handicapped step 4 and the rotating operation 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, the case where a handicapped person gets on the escalator from the lower floor and gets off at the upper floor is described, but there is essentially no difference in the case where a person with a disability gets on the escalator from the upper floor and gets off at the lower floor, and the present invention can be implemented. .

In the above embodiment, especially the levers 10, 10
0 by universal joints 10a and 110a (lever 1
0' is configured so that it can rotate within the plane of the inclination angle of the escalator (by tilting the shaft 11'),
If the lever 80 operates in a vertical plane as shown in FIG. Also, as shown in FIG. 9, the reason why the riser 42 of the adjacent step 4' is configured to be foldable is to prevent it from interfering with the beam 91.

〔Effect of the invention〕

As explained above, the present invention provides an auxiliary tread below the tread of at least one step among a plurality of steps of a passenger conveyor, has a simple structure in which the auxiliary tread can be freely pulled out in the front and back direction, and has a structure that allows the auxiliary tread to be freely pulled out in the front and rear directions. As for the adjacent upper step, the treadle is configured to be freely tiltable, and only when a disabled person uses the passenger conveyor, the pullout step and tiltable step are deformed to create enough space for a wheelchair or the like to ride. Not only can you safely ride the passenger conveyor by yourself, but the steps are usually the same size as a general passenger conveyor, so the sprocket that reverses 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, and the levers 10, 100 , 10' also rotate within the inclined angle plane of the escalator, so they do not interfere with the beam, and the present invention can use the main frame of the conventional passenger conveyor as is.
