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 if he/she is in a wheelchair, the escalator needs to be stopped once, and when getting off, the escalator needs to be stopped once so that the person can 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 exit of the destination floor, and after the 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 exit of the destination floor. Recently, a passenger conveyor has been proposed that can be used by people with disabilities by stopping the conveyor again.

[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]

The present invention provides a structure in which at least one step among a plurality of steps constituting a passenger conveyor is constructed so that a step plate can be freely pulled out in the front and back direction, and an inclined plate is rotatably provided at the rear end of the step plate of the step that can be freely pulled out. It is.

[Effect]

If configured as described above, the footboard can be made substantially wider only when used by a wheelchair user, and it is possible to prevent the footboard from falling off the step while driving.

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 carried out through the shaft 10, gear 21, gear 22, shaft 23, gear 24, gear 25, and shaft 26 to the arm 2.
7 and 29 clockwise, the guide plate 14 is rotated clockwise around the pin 14a via the link 28, and the shaft 26, gear 32, chain 35, gear 33, shaft 34, pinion 36, and rack are rotated clockwise. As shown in FIGS. 3 and 6, the step board 5 is sent out rearward via the link 37, and pushed back via the link 30 so that the board 31 closes the hole created by the step board 5. At this time, the treadle 5 is pulled out rearward with the pinion 45 meshing with the rack 49 fixed to the chain 48 wound between the chain gears 46 and 47, so that the chain 48 is moved as shown in FIG. 3a. Moving in the direction of the arrow, the inclined plate 13 is rotated 180° clockwise about the shaft 13a to 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 aforementioned two operations, ie, the pulling out operation of the handicapped step 5 and the tilting operation of the adjacent step 5', are performed in parallel to create a space sufficient for a wheelchair as shown in FIG. 13 to be accommodated.

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. 5, and rotates the guide plate 14' clockwise around the pin via the link 28' (shown in FIG. 4). In order to rotate the chain 48 through the shaft 40, gear 41, chain 44, gear 42, shaft 43, pinion 45, and rack 49 in the direction of the arrow in FIG. It rotates about 60 degrees counterclockwise around , stops at the position shown in Figure 6b, and acts as a wheel stopper. 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 step 4 stops at the exit, the switching guide rail (not shown) on the opposite side of the handicapped step 4 on the upper floor
is moved downward by a drive device (not shown) comprising a hydraulic device or the like, and in FIG. 5, the lever 39 is rotated counterclockwise about a shaft 40 via a roller 38. The rotational movement of this lever 39 is based on the shaft 4.

3. Move the chain 48 in the direction of the arrow in Figure 6b via the pinion 45 and rack 49, and rotate the inclined plate 13 about 60 degrees clockwise around the shaft 13a to the state shown in Figure 6a. do. In this state, a wheelchair can be accessed from a lower floor. Next, after the disabled person gets off the escalator, the recovery switch S
Press 3 to step 4 for disabled people on upper floors.
The switching guide rail (not shown) in front of the step 4' and the switching guide rails (not shown) on both sides of the adjacent step 4' are moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and as shown in FIGS. As the switching guide rail moves downward, the levers 9, 9' are rotated counterclockwise about the shafts 10, 10' by the spring pressure of the springs 11, 11'. First, this rotational movement of the lever 9 consists of the shaft 10, gear 21, shaft 23, gear 24, gear 25, shaft 26,
The guide plate 14 is rotated counterclockwise around the pin 14a via the arm 27 and the link 28, and the closing plate 31 is pulled into the inside of the step 4 for the disabled via the shaft 26, the arm 29, and the link 30.
The footboard 5 is connected via the shaft 26, gear 32, chain 35, gear 33, shaft 34, pinion 36, and rack 37.
bring back. At this time, the rack 4 fixed to the chain 48 wound between the chain gears 46 and 47
9 and the pinion 45 are engaged with each other, the treadle 5 is retracted, so the chain 48 moves in the direction opposite to the arrow shown in FIG.
The step is rotated 180 degrees counterclockwise around point a, resulting in the state shown in FIGS. 2a and 3a, and is reduced to a size no different from a normal step.

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 returned to the horizontal position 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 rotating operation will be performed in parallel, and the escalator will be 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 practiced essentially the same even when a disabled person gets off at an upper floor.

〔Effect of the invention〕

As explained above, the present invention has a structure in which at least one of the plurality of steps of a passenger conveyor is configured such that the tread plate can be freely pulled out in the front and back direction, and a tilted plate is rotatably provided at the rear end of the tread plate of the step that can be freely pulled out. By installing a sloping plate and using the slope plate as a stop for the car, not only can the tread be made substantially wider only when a wheelchair user uses the passenger conveyor, but it also prevents falling accidents. Not only can people ride on the passenger conveyor with peace of mind, but the steps can usually be made to be 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. The overall size of the passenger conveyor does not increase.
