Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in passenger conveyors such as escalators and electric roads.

The depth of the current &E escalator steps is approximately 40mm.
The size is around 0.000 mm, which is sufficient for general passengers to use, but when used by a physically disabled person using a wheelchair, the disadvantage is that the wheelchair is too large to use the escalator. there were.

On the other hand, when a person with a disability etc. gets on an escalator,
In particular, in the case of a wheelchair, it is necessary to stop the S-Riki Lake once, and it is also necessary to stop once to get off the wheelchair, and to get on and off safely.

For this reason, one or more large steps with a depth that is deep enough for a wheelchair to be installed 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. After a certain period of time, the large step is stopped again at the exit of the destination floor.
Recently, conveyors have been proposed that can be easily used by people with disabilities.

However, in such a passenger conveyor, even if there is a limited number of steps among the multiple steps, there is always a large step with a depth dimension (700 mm or more) that a wheelchair can ride on. 1. The radius of the chain gear device, etc. for reversing drive, which is reversed at the entrance/exit area, must be increased.1. There was a problem in that the body of the passenger conveyor that accommodated this was inevitably large, which restricted the installation space.

The present invention has been made in view of the above two points, in which the tread of any step is configured so that it can be freely pulled out in the depth direction, and the step on the side adjacent to the step that can be freely pulled out is configured such that it can be tilted freely. and only when used by persons with disabilities.
To provide a small man-con hair that can be satisfactorily ridden by a wheelchair by substantially widening the tread.

An embodiment of the present invention will be described below with reference to the drawings.

During normal operation, the step 4 for disabled persons is as shown in Figs. 2(a) and 3(a), and the adjacent step 4' is as shown in Figs. 4(a) and 6(a). , lever 10
．． The rollers 90, 90 and 9' provided on the guide rails 30, 130 and 7 switch between the guide rails 30, 130 and 7 near the entrances and exits in the lower and upper parts of the escalator.
0 (shown in FIGS. 3(a) and 6(a)), 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 level shown in Fig. 1 and presses the stop switch S for disabled people, the protrusion installed only on step 4 for disabled people, for example, is set to a limit. A well-known detection mechanism using a switch 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 rails 30 and 70 are horizontally moved by the drive devices 31 and 71, which are comprised of hydraulic devices, etc., and this operation causes the lever ]-0, 10'G; Figure 3(a) and Figure 6(a)

First, this rotational movement of the lever]-〇 is shown in Fig. 3(a) and (
In b) the axis 11. Gear 13. Gear 14. The pinion 16 is rotated counterclockwise around the shaft 15 via the shaft 15, and the treadle 6 is sent rearward via the rack 17 as shown in FIG. 3(b), and the link 26.2'7 ．．
29 and pin 26a.

The hole created when the footboard 6 is sent out is closed by the plate 28 by a link mechanism composed of 26b, 27a, 27b, 29a, and 29b. At this time, the rack 22 fixed to the chain 25 wound between the chain gears 23 and 24 and the pinion 2 are engaged, and the treadle 6 is pulled out rearward, so that the chain 25 is pulled out as shown in FIG. Moving in the direction of the arrow shown in (a), the inclined plate] 2 rotates 180° clockwise around 1IIll112a, resulting in the state shown in FIG. 3(b). Here, the pull-out of the dream tread 6 is determined by the operation of the lever 0, so when a disabled person is using the escalator, the roller 9 is guided by a guide rail so that the pull-out dimension of the tread 6 does not change. A locking mechanism is installed on 0 to prevent lever 0 from rotating while the escalator is in operation.

On the other hand, the rotational movement of the lever] C1' is shown in Fig. 6(a) and (

, the lever 50 is rotated counterclockwise around the entire center of the shaft 4.9 through the shaft 49, and the support position of the tread plate 6' by the roller 5] is moved downward. It leans backwards around the center. According to this tilting movement, the link mounting plate 57 is pushed backward by the link 55, and the shaft 58 rotates counterclockwise.
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, that is, the pulling out operation of the step 4 for disabled persons, the tilting operation of the adjacent step 4', and the folding operation of the riser 42, are performed in parallel to create a space sufficient for a wheelchair as shown in FIG. Create.

Note that the degree of inclination of the treadle 6/ in this adjacent step 4' depends on the shape of the guide tray /I/ 73 in which the roller is guided, so it will be the largest inclination in the slope section, and will be slightly inclined in the horizontal section. Guide rails 73 of a suitable shape are provided over the entire running section of the escalator.

Next, when the wheelchair enters the step 4 for disabled persons and presses the activation switch S2 for disabled persons, the switching guide rail 130 shown in FIG. , this action causes the lever]

In order to move the chain 23 through the rack 22 in the direction of the arrow in FIG. 3(1)), the inclined plate 12 is rotated approximately 600 times counterclockwise around the shaft 2a as shown in FIG. 3(c). Stop at position + t:, and act as a stop.

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 step 4 stops at the exit, the switching guide rail 1 of the handicapped step 4 on the upper floor

As the link mounting plate 57 rotates counterclockwise around the center, the shaft 58 rotates clockwise due to the force of the link mounting plate 57 being pulled forward by the link 55, and the gear 59. Gear 62. Axis 60. The riser 42 is exposed on the rear step side via the bracket 61 as shown in FIG. 4(a).
) and return to the normal step state shown in FIG. 6(a). 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 second floor and gets off at the lower floor, and the present invention can be implemented. can.

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. There is a risk that the riser 42 of the adjacent step 41 may interfere with the beam 91 supporting the guide rail 90 that guides the front wheel 7 or the rear wheel 8 of the step 4, as shown in FIG. The reason for this configuration is to prevent interference with beam 9].

As explained above, the present invention is such that at least one step of a plurality of steps of a passenger conveyor is configured such that a treadle can be freely pulled out in the front and back direction, and that the treadle is freely tiltable for the step adjacent to the step that can be freely pulled out. Only when a person with a disability uses a passenger conveyor,
In order to create enough space for wheelchairs, etc., by transforming the retractable steps and tiltable steps,
Not only can even disabled people safely ride the passenger conveyor alone, but the steps are usually exactly the same size as a general passenger conveyor, so the sprocket that reverses the steps is the same size as the sprocket on a conventional passenger conveyor. This means that 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 and the step when deformed. The main frame of the passenger conveyor can be used as is.
