Description

[Detailed Description of the Invention] [Technical Field of the Invention] This 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]

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 installed escalators for 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. 2
Since the user has no choice but to straddle steps and tilt the wheelchair, there is a high risk of the wheelchair falling, which is extremely dangerous.

Additionally, it is often impossible to install escalators with a special structure that carry both wheelchairs and general passengers 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 separate from escalators for general users. The disadvantage is that it must be installed.

[Purpose of invention]

This invention solves the above-mentioned conventional drawbacks, and provides a wheelchair auxiliary trolley for escalators on which a wheelchair can be placed and moved up the escalator, which allows a wheelchair user accompanied by an attendant to safely use a general escalator. be.

[Summary of the idea]

The wheelchair auxiliary trolley of this invention is designed for wheelchair users 1
The escalator 1 can be used with an attendant 12, and has a handle 2 for moving the trolley, and the frame portion 1A is attached to the escalator step S.
The truck frame 1 is bent into a chevron shape so as not to hit the stairs, and the front and rear ends of the chevron-shaped frame portion 1A of the truck frame 1 are provided with a wheel interval that spans two or more step surfaces of the escalator steps S. The front and rear wheels 3 and 4 are attached to the front and rear wheels 3 and 4, and the stair tread surface on which the front wheel 3 is mounted on the lower surface of the front wheel 3 side of the frame portion 1A.
A floor frame base on which is mounted an elastic body 5 with high frictional resistance attached so as to be able to come into contact with S', and a wheelchair 10 suspended within the trolley frame 1 so as to be swingable in the front and back direction using the upper pin joint part 7 as a fulcrum. 6, and a damper 13 for preventing the floor frame 6, which is pivotally connected between the truck frame 1 and the floor frame 6, from sudden tilting or rapid rocking motion, The floor frame 6 swings in response to the movement of forming a staircase from the horizontal part of the step, or vice versa, so that the wheelchair 10 can be moved on the escalator while always maintaining the wheelchair 10 in a horizontal state. This is how it was done.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a cart frame equipped with a handle 2 for moving the cart. Two or more steps of escalator steps S (implemented) are attached to the front and rear ends of the cart frame 1. In the example 3
There are provided a pair of front wheels 3 and a pair of rear wheels 4 on the left and right sides, which are mounted at a wheel interval that spans the step surface of the step. The lower both side frame portions 1A to which the front and rear wheels 3 and 4 are attached are bent into a mountain shape so as not to hit the escalator steps when forming the stairs.
An elastic body 5 for preventing slipping is attached to the lower surface of A on the front wheel 3 side, and is made of a rubber mat with a high frictional resistance and comes into contact with the stair tread surface S' on which the front wheel 3 rests, as shown in FIG. ing.

Reference numeral 6 denotes a floor frame on which a wheelchair 10 is placed, which is suspended within the cart frame 1 via a seesaw arm 8 so as to be swingable in the front and rear direction with the upper pin joint part 7 as a fulcrum. When the wheelchair 10 with the wheelchair 11 mounted thereon is mounted, the center of gravity is determined so as to be balanced in a substantially horizontal state, and the wheelchair 10 is pivotally supported by the pin joint 7 on the rear bent portion of the handle of the trolley frame 1. The handle 2 is used by the attendant 12 to move the trolley or to hold down the auxiliary trolley so that it does not fall during transportation on the escalator, and is used to hold the auxiliary trolley so that it does not fall off while being carried on the escalator. When the cart is pushed in, the frame 1 is tilted diagonally upward, but when the frame 1 is tilted as shown in FIG. It becomes easier to change direction to a nearly horizontal state. Reference numeral 13 denotes a damper provided to prevent the floor frame 6 from sudden inclination or sudden rocking, and is pivotally connected between the upright rod of the bogie frame 1 and the floor frame seesaw arm 8. Fluid pressure dampers, such as those using hydraulic or pneumatic pressure, are used.

Fig. 1 shows a state where the auxiliary trolley carrying the wheelchair 10 is placed on the horizontal part of the lower step of the escalator, and when the escalator step S starts to form a staircase from this state, the front wheels 3 are lifted and the The wheel 4 is placed on the third step as shown in Figure 2,
The truck frame 1 begins to tilt backward. However, since the floor frame 6 on which the wheelchair 10 is placed is pivotally pin-jointed to the frame part, it does not tilt, and the wheelchair 10 is maintained in a horizontal state according to the movement of the escalator steps S to form the stairs. Note that during this step movement of the step section, the damper 13 connecting the seesaw arm section 8 of the floor frame 6 and the frame 1 section gradually expands as the frame 1 tilts, but prevents rapid displacement. Therefore, sudden swinging and excessive pendulum movement of the floor frame base 6 are prevented. In addition, in the stair transportation state as shown in FIG.
Since it comes into contact with S' as shown in the figure, this anti-slip effect can reliably prevent the cart from sliding down.

When the auxiliary cart reaches the upper floor of the escalator and moves from the step section to the horizontal section, the floor frame 6 moves in the opposite direction to that when forming the stairs.
Rotation is performed around the pin joint part 7 of
The wheelchair 10 is moved on the escalator to the horizontal part of the upper floor while the floor frame 6 maintains the horizontal state of the wheelchair 10 without tilting. At this time, the damper 13 gradually contracts to prevent unnecessary pendulum movement. Incidentally, the auxiliary trolley transported to the upper floor of the escalator as shown in FIG. 3 is lowered from the escalator by the pushing operation of the attendant 12.

[Effect of idea]

According to the wheelchair auxiliary trolley of this invention, a wheelchair user accompanied by an attendant can safely use a general escalator, without causing anxiety or discomfort to the wheelchair user and the attendant. This provides excellent practical effects such as smooth escalator movement.
