Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) This invention synchronizes and interlocks a general standard basic escalator for transporting passengers and an auxiliary escalator for transporting wheelchairs for the disabled, large baggage, etc. This invention relates to escalators that are arranged side by side so that they can be operated.

(Prior art) Conventional escalators are mostly used to transport passengers, and for this reason, in accordance with the Building Standards Act, with the main focus on passenger safety, the inclination slope is 30 a or less, and the left and right sides of the steps are designed to rotate in synchronization with the steps. They are manufactured to specifications such as installing four railings with movable handrails, the width of the railing is 1.2 m or less, and the speed of the steps is 30 m/min or less, and the steps are generally about 400J+ in depth. #+, width 600m+ or 1000m
It is formed to have the same size as m.

(Problems to be solved by the invention) By the way, in the general standard escalator mentioned above,
It is extremely dangerous for disabled people in wheelchairs to use it. For example, if a wheelchair is placed on the steps of an escalator that is continuously moving up, the steps are small, so the wheelchair will straddle two steps and tilt upwards by about 30 degrees, making it extremely unstable even if the wheels are braked. Therefore, if the escalator suddenly stops due to the activation of a safety device, there is a risk that the escalator will fall due to the shock.

This means that the danger does not change much whether a disabled person rides with his own knife or if there is an attendant present. Moreover, when such a wheelchair falls, other general passengers are also at risk, which is a serious problem.

In addition, many people who travel overseas these days carry large trunks with casters as hand luggage, and in this case too, the luggage is unstable on a general escalator, and passengers have to support the large luggage so that it does not tip. They had to ride, which was both dangerous and often extremely inconvenient.

For this reason, there is a social need for escalators that can be used easily and safely by not only general passengers, but also disabled people using wheelchairs and their attendants, and conveniently used by passengers with large baggage such as trunks. There is a strong desire for its realization.

[Structure of the invention]

(Means for Solving the Problem) The escalator of the present invention was developed in view of the above circumstances, and in order to meet social needs, the escalator of the present invention is provided with a large number of basic steps arranged in an endless manner and with railings erected on the left and right sides of the steps. A general standard basic escalator for transporting passengers that rotates in synchronization with an endless moving handrail is provided in an inclined state across the upper and lower floors of a building, etc., and at least one side of the basic escalator is provided on the left and right sides. A large number of auxiliary steps that are wider in depth than the basic steps and have a larger pitch, and a number of auxiliary treads that do not have risers and are always parallel to the running surface are arranged alternately and connected in an endless manner, and on the outside thereof. An exercise device in which auxiliary escalators for transporting wheelchairs for handicapped persons equipped with handrails are arranged in parallel, and auxiliary steps and treadboards arranged in an endless manner of the auxiliary escalators are rotated in synchronization with the basic steps 4 of the basic escalator. It is characterized in that it is configured by providing.

(Function) With the above configuration, general passengers can ride the basic escalator and use the escalator by moving and holding the left and right handrails in the same manner as before. In addition, a physically handicapped person can ride the auxiliary escalator with his or her wheelchair either by themselves or with the help of an attendant, so that the wheelchair rests on the wide auxiliary step, and the footrest protruding forward from the casters of the wheelchair is placed on the auxiliary step one step in front of the auxiliary step. Because the wheelchair is positioned without interference on the auxiliary tread that is tilted parallel to the surface, the wheelchair is always maintained in a horizontal and stable state when being transported, and there is no risk of tipping or falling, and other general The wheelchair can be used safely regardless of passengers, and a large number of wheelchair users can use it safely one after another. Furthermore, passengers carrying large trunks or other luggage can conveniently place their luggage on the wide auxiliary steps of the auxiliary escalator.

(Example) An example of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the entire escalator seen from directly above, and FIG. 2 is a schematic configuration diagram of the escalator seen from the side. 1 in the diagram
2 is a basic escalator for transporting passengers, which is almost the same as a conventional standard escalator, and 2 is an auxiliary escalator for transporting wheelchairs for the handicapped, which is installed on one side of the basic escalator. are integrally constructed via a common truss 3 installed diagonally across the upper and lower floors of the building.

To explain in more detail here, first, the basic escalator 1
The structure is approximately the same as that of a conventional general escalator except for the common truss 3, in which a large number of basic steps 4 are connected endlessly by a pair of left and right step chains 5, and the front and rear wheels 6 of each basic step 4 are connected in an endless manner. It is provided so as to be rotatable in an end rail shape along a guide rail 8° into 9 provided in the truss 3 through 7°.

Further, the step chain 5 is hung from a driving wheel 10 provided on the upper floor side of the truss 3 and a driven wheel 11 provided on the lower floor side, and is provided coaxially with the driving wheel 10 on the upper floor side. The sprocket 12 is interlocked with a drive motor 13 shown in FIG. 1 via a drive chain 14, and the basic step 4 is rotated together with the step chain 5 by the rotation of the drive motor 13.

In addition, parapets 15 are erected from the truss 3 in the longitudinal direction at the left and right positions of the basic steps 4, and endless moving handrails 16 are provided so as to pass from the upper outer periphery to the lower interior of each of the left and right handrails 15. These left and right handrails 16 are rotatably driven by the drive motor 13 and rotated in synchronization with the basic step 4 via a sprocket, a transmission chain, etc. coaxial with the drive wheel 10.

On the other hand, the auxiliary escalator 2 has a common truss 3 adjacent to the left handrail 15 of the basic escalator 1.
This includes a large number of auxiliary steps 4A and holding treads 4B arranged one step at a time alternately with each other.
Left and right step chains 5A that connect them endlessly, guide rails 8A and 9A that guide the front and rear wheels 6A and 7A of each auxiliary step 4A and the front wheels 6B of each auxiliary step 4B, and the upper drive wheels 10A and lower This configuration consists of a driven wheel 11A on the floor side. An exercise device is provided so that the endless auxiliary steps 4A and 4B rotate in synchronization with the basic steps 4 of the basic escalator 1. That is, an interlocking sprocket 17 with a clutch 17a is coaxially provided on the driving wheel 10A on the upper floor side, and this is transmitted and driven via an interlocking chain 19 to a sprocket 18 coaxially provided on the driving wheel 10 of the basic escalator 1. The auxiliary step 4A and the auxiliary step 4B are connected to the basic escalator 1.
It is designed to rotate in synchronization with basic step 4.

Here, the auxiliary step 4A of the auxiliary escalator 2 has a top tread, a riser part, and front and rear wheels 6A and 7A, as in the conventional case.
However, each of the auxiliary treads 4B arranged every other step is simply a flat plate with a groove on the upper surface without a riser, and has only a front wheel 6B without a rear wheel. However, the rear end is supported by the shaft of the front wheel 6a of each of the rear auxiliary steps 4A, and is provided so as to be always parallel to the running surface (without floating up in a stepped manner like the auxiliary steps 4A). Further, each of the auxiliary steps 4A and 4B is wider in depth than the basic steps 4 of the basic escalator 1, and is arranged at a larger pitch.For example, the pitch P2 of the auxiliary steps 4A and 4B is the pitch of the basic steps 4. P! It is said to be twice as much. Further, each upper guide rail of the basic step 4, the auxiliary step 4A, and the auxiliary step 4B with respect to the reference line formed by the horizontal lines HL and LL of the upper and lower floors shown by dashed-dotted lines and the slope 11NL touching the riser upper edge corner of each basic step 4. 8,
The heights C of 9, 8A, and 9A are all the same. With this, the riser height H2 of the auxiliary step 4A is twice as large as the riser height Hl of the basic step 4.

Furthermore, in the auxiliary escalator 2, the entrances 20 on the upper and lower floors are connected to the ends of the handrails 15 of the basic escalator 1 (the movable handrails 1
6) is extended to the building law. In other words, the driving wheels 10A and driven wheels 11A on the upper and lower floor sides of the auxiliary escalator 2 are larger than those of the basic escalator 1 on the truss 3.
The running lengths of the horizontal parts of the upper and lower floors of the auxiliary steps 4A and 4B are set to be longer than those of the basic escalator 1 by the dimension D, and the entrances and exits on the upper and lower floors are A com 21 provided on the floor of the basic escalator 1 is located a distance E ahead of the end of the handrail 15 (inverted part of the moving handrail 16) according to the building law.

Further, a handrail 22 is erected on the outer side of the auxiliary step 4A of the auxiliary escalator 2 (on the side opposite to the basic escalator) over the entire length thereof. This outside railing 22 serves to prevent wheelchairs, luggage, etc. from falling, and also serves to prevent wheelchairs and luggage from falling.
Similarly to the basic escalator 1, the llIIl hanger 22 is also provided with a movable handrail 16A that can be rotated in synchronization with the auxiliary steps 4A and 4B, so that a handicapped person in a wheelchair or an attendant can grasp it with their hands. There is. In addition, this outer balustrade 22 is longer on the upper and lower floor sides than the balustrade 15 of the basic escalator 1, so that the upper and lower floor sides of the com 2 of the auxiliary escalator 2 are longer.
1, a switch operation panel 23 is provided on the inner surface of the protruding portion to command interlocking and stopping of the auxiliary escalator 2 by switching the clutch 17a of the exercise device on and off. In addition, an LCD TV 24 and Yasubika 25 are installed at the same location to provide information on how to get into a wheelchair and how to load luggage.

In addition, the auxiliary steps 4A and 4 of the auxiliary escalator 2
On the side opposite to the fixed railing of the horizontal running section on the upper and lower floors of B, very short bank-shaped partitions 26 are provided that extend further from the end of the railing 15 of the basic escalator 1. It has built-in safety devices such as a safety switch (not shown) that issues a command signal to stop escalator operation if stepped on strongly.

Furthermore, the common truss 3 of the basic escalator 1 and the auxiliary escalator 2 covers the entire space width including the handrails of both the escalators 1 and 2, and the elongated and large auxiliary steps 4A of the auxiliary escalator 2. The dimensions and shape are such that it has the length and depth necessary for rotation.

Therefore, with the escalator having the above-mentioned configuration, if a general passenger is currently climbing up the stairs, a general passenger who has come to the lower floor boarding/exit floor can simply get on the basic escalator 1 in the same way as before and move to the left and right handrails. 16, while being carried safely.

In addition, the disabled person S using a wheelchair first listens to #i! about the information broadcast from the speaker 25 and how to use the LCD TV 24 located at the end of the outside railing 22. Looking at the image, you or your attendant operate the clutch switching operation panel 23 to change the basic escalator 1 to the auxiliary escalator 2 or 3! make them drive dynamically. This allows the auxiliary steps 4A, 4B, and the movable handrail 16A of the outer handrail 22 to rotate endlessly in synchronization with the basic step 4 and the movable handrail 16. In this state, the handicapped person S gets on the auxiliary steps 4A from the lower entrance 20 of the auxiliary escalator 2 either by himself or with the help of an attendant in his wheelchair.

With this, the wheelchair is always stable in a horizontal state on the wide auxiliary step 4A, and the footrest protruding forward from the casters of the wheelchair is placed on the slanted auxiliary step 4A in front.
It comes to be located on B without being interfered with. This allows the wheelchair to be safely transported while being held horizontally without tilting at all, allowing the disabled person S to use it with peace of mind. In this case, the attendant can ride the auxiliary escalator 2 together with the disabled person S, or the attendant can ride the basic escalator 1 alone.In either case, the attendant will be transported in synchronization with the disabled person S, so the You will be able to ride comfortably and with peace of mind while observing the safety of the disabled person S. In addition, the disabled person S can get off the wheelchair from the upper floor entrance 20 either by themselves or with the help of an attendant. Since it is located in an extended position, it is possible to get off the train before the disabled person S and provide assistance without having to rush. After getting off the auxiliary escalator 2, it is possible to stop the interlocking of the auxiliary escalator 2 by operating the clutch switching operation panel 23 on the upper floor side, which is very convenient for the disabled person S or his/her attendant. It will be convenient and safe to use.

Furthermore, passengers with luggage such as large trunks can also use the system conveniently. To use it, first step over the partition 26 on the lower floor side and transfer the luggage from the lower entrance 20 of the auxiliary escalator 2 onto the auxiliary step 4A. Since the entrance 20 of the auxiliary escalator 2 extends a dimension E from the end of the handrail 15 of the basic escalator 1,
During this time, after confirming that the baggage is being carried stably onto the auxiliary step 4A, the passenger steps onto the basic step 4 of the basic escalator 1 in exactly the same way as when riding on a conventional general escalator. It's crowded. The passengers and their luggage are now transported to the upper floor at the same time by the basic escalator 1 and the auxiliary escalator 2, which are operated in synchronization with each other. At this time, because the depth of the auxiliary steps 4A is wide, the luggage does not tilt like in the past, and the outside railing 22
This prevents the vehicle from falling, allowing it to be safely transported in the same stable condition as passengers. At that time, passengers can also place their hands on their own luggage through the moving handrail 16 of the parapet 15, and in any case, they can be carried along with their luggage while observing its safety. When passengers get off on the upper floor, they first descend from the basic escalator 1, straddle the partition 23 on the upper floor, and are carried on the auxiliary steps 4A of the auxiliary escalator 2, which extends even further. The baggage is lowered onto the floor from the entrance 20 on the upper floor while holding the baggage with hands.

〔Effect of the invention〕

Since this invention has been made as described above, it can be used easily and safely not only by general passengers, but also by disabled people using wheelchairs and their attendants, and also by passengers with large baggage such as trunks. It becomes a convenient escalator.
