Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an escalator on which a wheelchair user accompanied by an attendant ascends and descends using an auxiliary trolley.

[Technical background of the invention and its problems]

BACKGROUND OF THE INVENTION With the development of transportation systems, railway station platforms and the like have been installed higher or lower than ground level, and as a result, an increasing number of stations have been equipped with escalators to facilitate the convenience of passengers.

However, it is extremely difficult for wheelchair users to use escalators, and even if they get on the escalator with an attendant, they will not be able to place the wheelchair horizontally on top of the first step of the escalator; Since the user has no choice but to straddle steps and tilt the wheelchair, there is a high possibility that the wheelchair will fall, which is extremely dangerous.

Therefore, in order to eliminate the above-mentioned drawbacks, the present applicant has invented a wheelchair auxiliary trolley for escalators having a structure as shown in FIGS. 1 and 2, and has filed a separate patent application.

Figure 1 below shows the structure of the truck related to this separate application.

To explain according to the drawing in FIG. 2, 1 in the figure is a main body of a cart on which a wheelchair B on which a wheelchair user A rides is placed, and both rear sides are connected by a cross beam 2 that can be held and pushed by an attendant C. Handle rods 3a and handle rods 3b on both sides of the front side, front wheels 4 on the front, rear, left and right sides that are pivoted with a distance between the axes that spans two or more, for example, three steps of the escalator steps S, and rear wheels made of rotatable casters. 5, and an intermediate wheel 6 that rises above the horizontal contact surface of the front and rear wheels 4.5 as shown in FIG. 7 moves the trolley body 1 on which the wheelchair B is placed to raise the rear wheel side and move the rear wheel side in accordance with the step forming movement from the step horizontal part SL of the escalator, or vice versa, the step horizontal forming movement of the step part SK. This is a device for lowering the truck and keeping it in a horizontal state at all times, and this truck horizontal maintenance device 7 includes a hydraulic cylinder 8 that operates with a piston in the direction of the step, which is placed vertically on the side of the rear wheels 5 of the truck body 1. A step contact body 9 is attached to the lower end of the screw I/rod 8a of this hydraulic cylinder (this step contact member is made of an elastic material such as nitrile rubber with high frictional resistance, and is actuated by the piston operation of the hydraulic cylinder 8). The trolley body 1 descends to the step 82 next to the step S1 on which the front wheels 4 touch the floor, and carries the wheelchair B.
In line with the step formation movement, the second wheel is moved around the front wheel 4 as a fulcrum.
As shown in the figure, the rear wheels are raised to a horizontal state, and a reverse raising operation is performed in accordance with the step horizontal formation movement.
The hydraulic power unit 10 (pump, motor, oil tank) is operated by operating a switch, and a battery 11 serves as a power source for its operation. Note that the operation switch 12 for operating the hydraulic cylinder 8 is located on the rear handle rod 3.
It is provided on the part of the handle that is held by the attendant C in a.

Next, to explain how to use the auxiliary trolley related to the separate application structured as described above, first, attendant C who has been pushing wheelchair B temporarily stops wheelchair B near the escalator entrance, and then The wheelchair B loaded with the user is placed on the auxiliary trolley, and the auxiliary trolley carrying the wheelchair is pushed to the escalator entrance (hereinafter, the case of the lower floor entrance will be described), where the escalator driver enters the escalator. 1, and then place the trolley on the horizontal part SL of the escalator steps S. After getting on this trolley, the escalator is started.

Manual or automatic escalator operation is performed in which the escalator is stopped when the cart reaches the horizontal part of the upper step of the escalator.

In this case, the attendant C lowers the hydraulic cylinder 8 by operating a switch in accordance with the stair formation movement from the lower step horizontal part SL of the escalator, and moves the step contact body 9 at the lower end of the piston rod 8a to the step surface S2. The trolley body 1 on which wheelchair B is placed is brought into contact with the floor and pushed up by the action of pushing up from the floor.
The rear wheel is raised using the front wheel 4 as a fulcrum as shown in FIG. 2, and is moved upward while always maintaining a horizontal state. Immediately before the escalator step S carrying the auxiliary cart moves from the stair portion SK to the upper stair step horizontal portion and stops, the operation switch 12 is actuated again, and the step horizontal formation movement from the stair step portion SK is performed. At the same time, the hydraulic cylinder 8 and the step contact body 9 at the lower end of the cylinder piston rod 8a are moved upward. In this way, the auxiliary trolley carrying a wheelchair can be raised from the lower floor entrance of the escalator to the upper floor entrance in a state that is always maintained horizontally, and the wheelchair loaded on the escalator, which has been conveyed and stopped at the horizontal part of the upper stairway. The auxiliary trolley has front and rear wheels 4 and 5.
With the product in contact with the floor, it can be easily pushed out to the floor of the escalator's upper entrance.

The structure and operation of the wheelchair auxiliary trolley related to the above-mentioned separate application are as described above, and this auxiliary trolley and the auxiliary trolley of another application related thereto (the above-mentioned trolley horizontal maintenance device 7)
including those with a set of manual push-up levers, etc.)
A wheelchair auxiliary trolley for an escalator that allows a wheelchair user to use an escalator accompanied by an attendant is provided with If it is not placed in the correct position, the tip of the trolley body 1 may hit the step riser Sa as shown in the first drawing section, damaging a part of the riser, or the safety switch inside the escalator (not shown) may be damaged after the escalator moves. This causes problems such as activating the escalator and stopping the escalator. Also, change the position of the front wheel 4 to the riser sb of the step S.
If it is placed close to the side, when the step S rises due to the escalator's step formation movement, the step contact body 9 at the lower end of the piston rod of the bogie leveling device 7 (hydraulic cylinder 8) will move to the section E in Fig. 2. As shown in the figure, there was a risk that the wheelchair user and his/her attendant would fall off the auxiliary trolley carrying the wheelchair due to the wheelchair touching the end of the step S, causing the trolley to become unbalanced.
