Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a wheelchair auxiliary trolley for an escalator used when a wheelchair user uses an escalator.

[Technical background of the invention and its problems]

With the development of transportation, the platforms of railway station buildings are being installed higher or lower than the ground, and as a result, an increasing number of stations are installing escalators to improve passenger convenience. .

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, and the second step will be difficult to use. 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.

Additionally, escalators with a special structure that carry both wheelchairs and general passengers cannot often be installed due to the structure of station buildings, etc. On the other hand, there are places where escalators exclusively for wheelchairs are installed, but they are not escalators for general users. The disadvantage is that it must be installed separately.

Therefore, in order to eliminate the above-mentioned drawbacks, the present applicant has filed a patent application separately from this invention for a wheelchair auxiliary trolley for escalators having the structure shown in Figs. 1 to 3 (hereinafter referred to as This patent application is called a separate application).

Hereinafter, the structure of the trolley related to this separate application will be explained with reference to the drawings in FIGS. 1 to 3. In the figure, 10 is the main body of the trolley on which the wheelchair B on which the wheelchair user A rides is placed, the floor plate 1 on which the wheelchair B is placed, A side frame 2 consisting of a plate-shaped body placed on both the left and right sides of this floorboard,
Attendant C erected and fixed on this side frame 2
consists of rear side handle rods 5a and front side handle rods 5b (wheelchair stoppers 6 are provided on these handle rods), which can be held and pushed by hand, and which are connected to both front sides of the trolley body 10. On both sides of the rear part, a front wheel 3 and a rear wheel 4 consisting of a freely rotatable caster are pivoted with a distance L between the axes spanning three steps of the escalator steps S as shown in FIG. 7 moves the trolley body 10 on which the wheelchair B is placed to the rear wheel side in accordance with the step forming movement as shown in FIG. It is a device for raising and lowering the rear wheel side and maintaining it in a horizontal state, and this bogie horizontal maintenance device 7 operates a piston in the direction of a step attached vertically to the rear wheel side mounting plate 2a of the bogie main body 10. a hydraulic cylinder 8;
A step contact body 9 is attached to the lower end of the piston 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 moved forward by the piston operation of the hydraulic cylinder 8). The wheel 3 descends into contact with the surface of the step S2 next to the step S1 on which the wheel 3 touches the floor, and the trolley body 10 carrying the wheelchair B is placed in a horizontal state as shown in the upper right of FIG. hydraulic power is mounted on the truck body 10 and operates the hydraulic cylinder 8 by the attendant C's switch operation. It consists of a unit 11 (pump, motor, oil tank) and a battery 12 for its operating power source. The operating switch 13 for operating the hydraulic cylinder 8 is provided on the handle portion of the rear handle rod 5a that is held by the attendant C with his or her hand.

Therefore, 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 stops wheelchair B near the escalator entrance, and then The wheelchair B loaded with the user is placed on the prepared 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). Then, the trolley is suspended from the horizontal part SL of the lower step of the escalator step S in the position shown in FIG. 3 and stopped. Manual or automatic escalator operation is performed in which the escalator is started after the cart is boarded, and the escalator is stopped when the cart reaches the horizontal part of the upper staircase 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 stair step horizontal part SL of the escalator, and then lowers the hydraulic cylinder 8 to move the step floor body 9 at the lower end of the piston rod 8a.
is brought into contact with the surface of the step S2, and by its pushing up action, the trolley body 10 on which the wheelchair B is placed is raised on the rear wheel side using the front wheels 3 as a fulcrum as shown in the upper right corner of Figure 3, and maintained in a horizontal state. Move it upwards while doing so. Immediately before the escalator step S moves from the stair portion SH to the upper stair step horizontal portion and stops, the operation switch 13 is operated again, and the hydraulic cylinder 8 is activated in accordance with the step horizontal formation movement from the stair step portion SH. , and the step floor body 9 at the lower end of the cylinder piston rod 8a is moved upward. In this way, the wheelchair-mounted auxiliary trolley can be raised from the lower escalator entrance to the upper escalator entrance in a horizontal state, and the wheelchair-mounted auxiliary trolley that has been conveyed and stopped at the horizontal part of the ascending step of the escalator can be raised. The truck has 3 front and rear wheels,
4 is in contact with the floor, it can be easily pushed out to the floor side of the upper escalator 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 is equipped with control equipment for the hydraulic cylinder control device (terminal block for electrical wiring, relay, hydraulic circuit directional control valve). etc.) are installed on the floor plate 1 of the trolley body 10, which may get in the way when wheelchair B is put in and taken out of the trolley body 10, and wheelchair B may hit and damage the control equipment. It is difficult to maintain (repair/inspect) the trolley body 10.
There were problems such as the fact that the control equipment could not be housed in the side frame 2 of the truck, and that the truck main body 10 could not be constructed compactly.

[Purpose of the invention]

The object of the present invention is to provide a wheelchair auxiliary trolley for an escalator which solves the problems mentioned above in the separate application.

[Summary of the invention]

In order to achieve the above-mentioned object, in the first invention, the side frame of the bogie main body is constructed of L-shaped, groove-shaped, etc. shaped steel attached so that the flange edge is located on the outside, In the second invention, at least one control device (for example, a terminal block for electrical wiring) of the hydraulic cylinder control device is mounted inside the shaped steel, and a removable cover is provided to cover the mounted device. Other control equipment (e.g., relays, hydraulic circuit directional control valves) that is not housed in the side frame on the side frame of the section steel
The device is characterized in that it is provided with an upper cover that is removable from the outside and covers the equipment mounted on the frame.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings of FIGS. 4 to 6. This wheelchair auxiliary trolley for escalators allows wheelchair user A to use the escalator accompanied by an attendant C.
