Description

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

The depth of the current escalator steps is approximately 400 mm.
-111, and this size is sufficient for general passengers to use, but if used by a physically disabled person who uses a wheelchair, the disadvantage is that the wheelchair is too large and the escalator cannot be used. there were.

On the other hand, when a person with a physical disability gets on an escalator,
In particular, in the case of a wheelchair, it is necessary to partially stop the escalator, and even when getting off, it is necessary to stop once 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 be installed are installed in advance, and a passenger conveyor exclusively for the disabled is activated. A stop switch is installed at the entrance. By operating this stop switch, 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 steps are stopped again after a certain period of time, that is, at the exit of the destination floor, so that even people with disabilities can fully use them.

However, in such a passenger conveyor, even if there is a limited number of steps among the multiple steps, a large step with a depth (more than 700 steps) that can accommodate a wheelchair is reversed at the entrance. , The radius of the chain gear device for reverse drive is too large. There was a problem with the Manconhair aircraft that housed it being too large, which restricted the space it could be placed in.

The present invention has been made in view of the above points, and is designed so that the treads of any step can be freely pulled out in the depth direction, and only when used by a disabled person, the treads are substantially widened and small enough to accommodate one wheelchair. The purpose is to provide a man conveyor.

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

FIG. 1 is an overall side view of an escalator showing the present invention, in which 1 is the escalator body, 2 is a handrail 13 is a step for general passengers, and the depth dimension is about 400 IIll as described above.

Reference numeral 4 designates a step for the handicapped person whose treadle can be freely pulled out in the depth direction, as will be described later. S1 is a stop switch exclusively for disabled people.When a disabled person wants to use the escalator, if he or she presses this switch S1, the steps for disabled people are automatically stopped at the entrance, and then the treadle is pulled forward by a mechanism to be described later. s2 is a start switch for disabled people that is activated after a disabled person gets on the escalator, S

In Fig. 3, 51 is a guide rail for guiding the front wheel 6, 52 is a guide rail for guiding the rear wheel 7, and 56 is a guide rail 52.
A drive device 6 consisting of a hydraulic device, etc.
This is a switching guide rail configured to be able to be raised and lowered by o.

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

During normal operation, the step 4 for handicapped persons (as shown in FIGS. 2(a) and 3(a)) is operated by the rollers 8 and 8' provided on the levers 9 and 9'. Since the step only contacts the switching guide rail 56 near the entrance/exit, the external structure and movement are no different from a normal step. Here, when a disabled person in a wheelchair comes to the entrance of the upper floor shown in Fig. 1 and presses the stop switch S1 for disabled people, for example, the protrusion provided only on the step 4 for disabled people is activated by the limit switch. A well-known detection mechanism detects when the handicapped step 4 rotates to the upper entrance and stops the escalator. Next, the switching guide rail 53 is moved upward by a drive device 60 consisting of a hydraulic device or the like, and this operation causes the lever 9 to rotate clockwise about the shaft 10 against the spring pressure of the spring 11. This rotational movement of lever 9 is caused by shaft 10. in FIGS. Gear 21° Gear 22. QII23. Gear 24. Gear 25. The arms 27.29 are rotated clockwise via the shaft 26, the guide plate 14 is rotated clockwise about the bin 14a via the link 28, and the shaft 26.29 is rotated clockwise via the link 28. Gear 32. Chain 65. Gear 36° shaft 34 and pinion 36. The step board 5 is sent out rearward through the rank 67 as shown in FIGS. 6 and 6, and pushed back through the link 30 so that the board 31 closes the hole created by the sending 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 that the first chain 48 is shown in FIG. 6(a). The inclined plate 16 is rotated 180° clockwise about the shaft 13a to be in the state shown in FIG. 6(a).

Next, when the wheelchair enters the handicapped step 4 and presses the disabled handicap start switch S2, the switching guide rail (not shown) on the opposite side shown in FIG. (not shown).
This action causes the lever 9' to rotate about the shaft 40 in the clockwise direction. In FIG. 5, this rotational action of the lever 9' rotates the arm 27' clockwise via the shaft 40, and rotates the guide plate 14' clockwise about the bottle via the first link. Gear 41. Chain 44. Gear 42° shaft 43 and pinion 45. rack 49
In order to move the chain 48 in the direction of the arrow in FIG. 6(a) through It stops and acts as a traffic stop. The escalator then starts operating and automatically stops the escalator when the handicapped step 4 reaches the lower floor. When the handicapped step 4 stops at a predetermined position at the exit, the switching guide rail (not shown) on the lower floor on the opposite side is moved downward by a drive device (not shown) consisting of a hydraulic device, etc., and the roller 8
' The lever 9' is rotated in the counterclockwise direction together with the shaft 4o. The rotational movement of this lever 9' is caused by a shaft 40. The arm 27' rotates the opposite guide plate 14' counterclockwise around a pin (not shown) via an IJ link (not shown), and rotates the shaft 40. Gear 41. Chain 44° Gear 42. Axis 46.

The chain 48 is moved in the direction of the arrow in FIG. 6(b) through the slanted plate 16, and the inclined plate 16 is rotated about 60 degrees in the clockwise direction about the shaft 13a, so that it is in the state shown in FIG. 6(a). Make the wheelchair accessible.

Next, after the disabled person gets off the escalator, turn on the recovery switch S.
Press 6 to switch the lower floor switching guide rail (not shown).
is moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and the lever 9 is rotated counterclockwise together with the shaft 10 via the roller 8. The rotational movement of this lever 9 is caused by a shaft 10, a gear 21. Axis 26. Gear 24. Gear 25° shaft 2

As explained above, the present invention is such that the tread of at least one step of a plurality of steps of a passenger conveyor can be freely pulled out in the front and back direction, and only when a disabled person uses the passenger conveyor, the tread of the step can be pulled out. Not only can it be used with one hand, but the sprocket that reverses the steps is the same size as before, so the body of the passenger conveyor does not become unnecessarily large.
