Description

Disabled lift entry platform {Disabled lift entry platform}

The present invention relates to a wheelchair lift installed on a bus, and in particular, when the lift drawn out of the lift storage box rotates upward and reaches the riding position of the bus, the bottom plate of the lift and the inside floor of the bus are connected to the lift from the wheelchair bus to the lift. Or, it is spread so that it can be safely moved from the lift to the bus, and it is configured to be folded vertically so that the wheelchair does not fall when turning up and down.

The reason that it is difficult for people with disabilities to use public transportation is because of the difference between the height of the vehicle's interior floor and the ground, and a low-floor bus was developed and commercialized to solve this problem.

1 is a side view showing a low-floor bus according to the prior art, and FIG. 2 is a conceptual diagram showing an operation relationship of a slope in the low-floor bus shown in FIG. 1.

1 and 2, the low-floor bus 10 is a bus designed by lowering the floor of a vehicle where passengers are located, and when the slope 11 for the disabled mounted on the low-floor bus 10 is drawn out to the ground It is configured to push the wheelchair (1) to be able to board.

However, in the case of a high-speed bus or the like running a long distance, the cargo compartment is located under the floor of the vehicle where the passenger is located as the cargo and the like have to be stored and moved.

Therefore, the high-speed bus with a cargo compartment cannot lower the floor like the above-described low-floor bus, so it is impossible to install a slope for the disabled.

The lift for the disabled was developed to solve the problem of the slope for the disabled.

In the drawing, FIG. 3 is a front view of a bus equipped with a lift for a disabled person according to the prior art, and FIG. 4 is a conceptual view showing an operation relationship of a lift in a state in which the lift door shown in FIG. 3 is opened.

As shown in FIG. 3, the bus 20 for the disabled has a door 21 on which the general public can get on and off on the front side, and a middle door 23 on which the disabled person with a wheelchair 1 can get on and off on the middle side. ) Is formed, the lift door 30D is formed in the storage box 25 located under the middle door 23, and the lift 30 for moving the wheelchair in the vertical direction is built in the storage box 25.

And after opening the lift door 30D and the middle door 23, as shown in Figure 4, after operating the lift 30, the lift 30 comes out of the storage box of the bus after the lift 30 is seated on the ground On the contrary, the lift 30 located at the top moves downwards, seats on the ground, and enters the inside of the storage box 25 of the bus 20 for the disabled.

On the other hand, when the lift rotates upward and is located at the same level as the floor inside the bus, the operator unfolds the exit foot so that the exit foot rests on the floor inside the bus. Then, the wheelchair can be moved from the bus to the lift or from the bus to the lift through the open stepping board, so you can get on or off through the lift.

However, there is a problem in that the conventional stepping-off step requires the operator to unfold or fold according to the position of the lift. In particular, if the operator spreads the footing while the lift is turned upward, the worker located on the ground is high enough to spread the footing, and it is low to spread the footing inside the bus, so there is a risk of falling into the open door on the bus.

As shown in Figure 5, the lift 110 for the disabled is configured to be drawn in or out in the storage box 101, the storage box 101 is installed in the cargo compartment of the bus 20, as described above, the lift 110 Turns between the ground and the middle door 23 of the bus 20 in a state that is withdrawn from the storage box 101 and helps a wheelchair or a disabled person who has boarded the lift 110 to get on the bus 20 or get off the ground. Help you do it.

In the lift 110 for the handicapped shown in FIG. 5, folding handles 113 are mounted on both sides of the bottom plate 111 of the lift 110, and the wheelchair 1 is grounded at the front end of the bottom plate 111. The entrance plate 115 is mounted to be folded or unfolded so as to be able to move between the floor plate 111 and the rear end of the floor plate 111, a wheelchair (1) between the bottom plate 111 and the inner floor of the bus 20. ) Is mounted so that the stepping plate 120 is folded or unfolded so that it can move.

And the bottom plate 111 is connected to one side of the orbiting link 117, the orbiting link 117 is coupled to a transfer frame that moves in the longitudinal direction of the box 101 from the inside of the box 101.

Lift lift footrest 120 for the disabled according to the present invention, the wheelchair (1) is smoothly lifted from the lift 110 to the inside of the bus or from the inside of the bus lift 110 so that the lift 110 is similar to the bottom surface of the bus When positioned (hereinafter referred to as a high point), it operates to spread inside the bus, and when the lift 110 moves below the high point, it is folded vertically and fixed so that the wheelchair does not fall out of the lift.

As shown in FIG. 6, the spring 140 and the lift 110 that provide elastic force to pivot in the direction in which the advance stepboard 120 which is hinged to the advance side of the lift 110 and pivotable in the vertical direction are extended, and the lift 110 Mounted on the bottom, as the storage box 101 moves forward, the unfolded stool 120 is pushed to be folded, and the slide bar 160 interferes with the stool 120 so that it is not unfolded in the folded state. Wow, the slide bar 160 is moved in the front-rear direction by the difference between the bottom plate 111 and the turning link 117 that are connected to the turning link 117 connecting the lift 110 and the storage box 101 to turn. It includes a connecting portion 150 for connecting the swing link 117 and the slide bar 160 to move.

Below, the lift platform for the disabled for the disabled will be described in detail.

5 and 6, the hydraulic cylinder 130, which is a telescopic member, is telescopically mounted on the pivot link 117 connecting the lift 110 and the storage box 101, so that the hydraulic cylinder 130 is One end of the pivot link 117 and the hydraulic cylinder 130 is coupled to the storage box 101. Therefore, by the expansion and contraction of the hydraulic cylinder 130, the turning link 117 moves the lift 110 upward or downward while turning, and a difference occurs between the turning link 117 and the lift 110.

Hereinafter, the connection part 150 connected to the turning link 117 will be described.

As shown in FIG. 6, the fixing bracket 151 is fixed in the middle of the length of the turning link 117, and one end of the link 153 is hinged to the fixing bracket 151.

On the bottom plate 111 of the lift 110, a horizontal bar 155 positioned in the width direction of the bottom plate 111 is located, and the horizontal bar 155 is hinged to the other end of the link 153. Here, in order to reinforce the bottom plate 111, the bottom surface of the bottom plate 111 has a fixed reinforcing frame 116 and a bottom bar of both side walls 112 of the lift 110 through which a horizontal bar 155 penetrates and moves. (119) are formed.

In addition, in the middle of the length of the horizontal bar 155, the slide bar 160 is fixed in the forward direction, and the slide bar 160 moves forward or backward in the direction in which the stepping plate 120 is located, and pushes the stepping plate 120 in a folding direction, that is, Turn upward. In this state, if the slide bar 160 is further advanced, it interferes with the slide bar 160, so that the stepboard 120 is positioned in a standing state without turning downward.

Therefore, the lift 110 is rotated in the vertical direction by the expansion and contraction of the hydraulic cylinder 130, and at this time, the fixed bracket (which is one of the configurations of the connection part 150) by the difference in angle between the lift 110 and the swing link 153 The link 153 hinged to 151) pivots around the hinge. By turning the link 153, the horizontal bar 155 moves forward and backward along the long hole 119, and the slide bar 160 fixed in the middle of the length of the horizontal bar 155 moves forward and backward, and moves the stepboard 120 through. Orbit.

Here, in the process of the lift 110 moving upward and reaching the high point, the slide bar 160 also retreats in the state in which it interferes with the stepping plate 120 so that when the lift 110 reaches the high point, it retracts to the maximum. do. Conversely, when the lift 110 rotates downward from the high point, the slide bar 160 pushes the advance step 120 while advancing in the most retracted state and advances further to prevent the advance step 120 from turning downward ( 120).

On the other hand, the stepping plate 120 is folded by turning upward by the advance of the slide bar 160 in a hinged state with both side walls 112 of the lift 110, and conversely by the reverse of the slide bar 160 You can turn downward or unfold.

In order to minimize the impact generated by interference with the slide bar 160, the rubber roller 121 is mounted on the entry and exit plate 120 at a point where it interferes with the slide bar 160. Therefore, when the slide bar 160 that was retracted is in contact with the rubber roller 121 while advancing, and when the slide bar 160 is further advanced in this state, the rubber roller 121 is pressurized so that the advancement foot 120 is turned upward. do. At this time, the rubber roller 121 is positioned at an upper side away from the top of the slide bar 160 at the tip of the slide bar 160 that rotates and advances.

In this state, when the slide bar 160 is further advanced, the rubber roller 121 is located at the upper portion of the slide bar 160 and supports the advancement plate 120 so as not to turn downward.

On the other hand, a spring is positioned between the stepping plate 120 and the lift 110 to provide an elastic force to pivot downward in the direction in which the stepping plate 120 is deployed. The spring is fixed to the bottom plate of the lift 110 by the torsion spring 140 and the other end is fixed to the stepping plate 120 to provide elastic force to the pivotable stepping plate 120.

In addition, a guide 157 is fixed to the bottom plate 111 so that the slide bar 160 can slide to the correct position on the bottom surface of the bottom plate 111, and a hemispherical rubber 161 is formed at the tip of the slide bar 160. ) Is fixed.

The following describes the operational relationship of the lift entry and exit platform for the disabled.

As shown in FIGS. 7 and 8, the lift 110 is withdrawn from the storage box 101 under the control of the driver, and the lift 110 is turned upward to get off the wheelchair 1 on the bus, and vice versa In order to get on the lift 110 from the ground, the wheelchair 1 is turned downward.

Hereinafter, a description will be given of a process in which the lift 110 moves downward to a high point in a state where the wheelchair 1 is placed on the bottom plate 111 of the lift 110 because the lift 110 is positioned downward.

When the lift 110 is in contact with the ground, the angle of the lift 110 and the turning link 153 is narrowed, so that the horizontal bar 155 is fully advanced along the long hole 119, as described above. In the state, the slide bar 160 is positioned below the pivoting stepboard 120 so that the stepping board 120 is not expanded.

In this state, when the wheelchair is boarded on the lift 110 and the entrance platform 115 is locked, the wheelchair located on the bottom plate 111 of the lift 110 has both side walls 112 of the lift 110 and an established entrance platform ( 120) In addition, even if a malfunction occurs in the lift 110 by the standing stepboard 115, it does not fall out of the lift 110.

In this state, as the length of the hydraulic cylinder 130 is extended, the turning link 117 turns, and accordingly, the lift 110 also turns upward. At this time, the angle between the swing link 153 and the lift 110 gradually increases.

When the angle between the swing link 153 and the lift 110 increases, the horizontal bar 155 connected to the link 153 moves backward along the long hole 119. Even when the slide bar 160 is reversed along with the reverse of the horizontal bar 155, the advanced step 120 is pivoted downward when the tip of the slide bar 160 interferes with the rubber roller 121 of the advanced step 120. When the lift 110 reaches the high point, the slide bar 160 is completely retracted from the rubber roller 121 in a state in which it is fully retracted, so that the advancement foot 120 can be pivoted downward. As the elastic force of the torsion spring 140 is always provided in the direction in which the advance step 120 is unfolded, the advance step 120 is unfolded when the tip of the slide bar 160 is completely out of the rubber roller 121.

At this time, the lift 110 is located in the high point, the exit plate 120 is located between the floor inside the bus 20 and the lift 110 exposed through the open middle door 23, so that the wheelchair enters the base plate 120 ).

On the other hand, when the lift 110 is moved downward from the high point, as described above, the slide bar 160 moves forward and pushes the rubber roller 121 of the stepping plate 120 with a force greater than the elastic force of the torsion spring 140. Accordingly, the stepboard 120 is blocked from turning so as not to turn downward due to interference with the slide bar 160 while turning upward and standing up.
