Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for raising and lowering a wheelchair of a vehicle, which guides the wheelchair into a vehicle interior by a slope.

[0002]

2. Description of the Related Art Conventionally, as a lifting device for a wheelchair of a vehicle, for example, a device shown in FIGS. 18 to 20 is known.

The lifting device includes a first slope A1 having a base end rotatably supported at a position near a rear end of a floor of a vehicle body, and a base end rotating at a tip end of the first slope A1. The folding slope A is provided with a two-fold folding slope A composed of a second slope A1 that is supported so that the folding slope A can be used outside the vehicle compartment through a back door opening B of the vehicle body as shown in FIG. And is extended between the floor C of the vehicle body and the ground behind the vehicle in the deployed state. Further, at the time of storage, as shown in FIG. 20, it is folded in two in a state of being set substantially at right angles so as to be parallel to the back door D, and is housed in the vehicle interior.

[0004]

However, in such a conventional vehicle wheelchair elevating device, when the folding slope A is stored, the opening area of the back door opening B of the vehicle is reduced by the folding slope A. You will be restricted. For this reason, when loading luggage or the like without loading a wheelchair on the vehicle, the folding slope A becomes an obstacle,
Loading and unloading of luggage through the back door opening B becomes difficult.

[0005] Further, in this conventional lifting device, since the first slope A1 and the second slope A2 are only connected via the shaft member, the operation of the folding slope A when the slope is folded is not stable. . That is, when the second slope A2 is lifted, the folding slope A as shown in FIG. 20 becomes the first slope A1 and the second slope A2.
It is not always the case that the correct state is bent between the two.
Therefore, depending on the force applied when the second slope A2 is lifted, the first slope A1 and the second slope A
The workability at the time of folding the slope is poor due to lifting up while keeping the space between the two straight.

[0006] Further, at the time of folding or unfolding as described above, since a force work such as lifting the second slope A2 is required, it is difficult to use for the physically handicapped and the elderly. .

The present invention has been made in view of such a conventional problem, and does not hinder the loading and unloading of luggage from the back door opening. It is an object of the present invention to provide a lifting device for a wheelchair of a vehicle, which can be changed without accompanying the problem.

[0008]

According to the present invention, in order to solve the above-mentioned problems, a base end portion is rotatably supported at a position near a rear end portion of a floor of a vehicle body. A folding slope having a slope and a second slope whose base end is rotatably supported at the distal end of the first slope is provided, and the folding slope is folded and stored in the vehicle interior in a retracted state. Lift device for a wheelchair, which can be accommodated in the vehicle and is drawn out of the cabin through the back door opening of the vehicle body in the unfolded state and can be slantly bridged between the rear end of the floor and the ground behind the vehicle. , A slope link whose one end is rotatably supported by the second slope and whose other end is rotatably supported at a position near the rear end of the floor of the vehicle body is substantially the same as the first slope. Set up in parallel A link mechanism is constituted by the slope link, a part of the vehicle body and the second slope, and the link mechanism is configured to move the second slope substantially in parallel between the retracted state and the deployed state. On the other hand, a rotation center axis is provided at the base end of the first slope, and driving means for driving the rotation center axis to form the retracted state and the deployed state is provided.

In this configuration, when the driving means is operated, the first slope is driven, and the second slope is driven via the first slope and the slope link. State, so that there is no difficulty in changing from the stored state to the expanded state or from the expanded state to the stored state. Further, in the retracted state, the first slope falls down on the vehicle body floor, and the second slope moves in parallel to reach the first slope. Can be widely secured.

According to a second aspect of the present invention, the driving means includes a motor, a speed reduction mechanism meshed with an output shaft of the motor, and the rotation center shaft meshed with the speed reduction mechanism. It is a drive unit. Therefore, the required driving torque can be obtained using a small output motor,
The slope can be driven at an appropriate speed, and the arrangement space can be minimized by unitization.

According to the third aspect of the present invention, while the roller is disposed on the vehicle body side, the distal end of the first slope abuts on the roller in the retracted state,
A guide surface is formed along the movement trajectory from the stored state to the expanded state. Therefore, at the initial stage of the transition from the stored state to the deployed state, the guide surface abuts against the roller, thereby assisting movement in the starting direction, and smooth movement can be started with a small torque.

Further, in the invention according to claim 4, at least one of the right side and the left side of the rear part of the vehicle compartment is foldable along the side wall of the vehicle body and is placed on the second slope in the retracted state. An expandable folding sheet is provided, and a first slope folded below the second slope is provided with a sheet striker which can be engaged with a lock of the folding sheet in the folded sheet unfolded state. An opening for exposing the sheet striker is provided on the two slopes.

Therefore, since the folding seat is provided at the rear part of the vehicle body, the folding seat can be developed when the wheelchair is not mounted on the vehicle. And the first
Since the sheet striker is provided on the slope and the opening for exposing the sheet striker is provided on the second slope, when the folding slope is folded and the folded sheet is deployed, the opening of the folded sheet is locked. Through this, the sheet can be engaged with the first slope sheet striker, whereby the folded sheet can be locked in the expanded state.

Further, in the invention according to claim 5, the second slope is provided with a lid for opening and closing the opening, and the first slope is provided from the deployed state to the stored state. An interfering member is provided for interfering with the lid and opening and driving the lid along with the transition. Therefore, in the unfolded state, the opening can be closed by the lid, and the non-opening state can be obtained, and when the folding slope is changed from the unfolded state to the retracted state, the lid is opened to open the sheet from the opening. The striker is exposed, and the folding sheet can be locked quickly.

[0015] In the invention according to claim 6, the lid and the interference member are provided with engaging portions that engage with each other. Therefore, conversely, when shifting from the stored state to the deployed state, the lid is driven to close to close the opening,
A safe slope without openings is formed.

In addition, in the invention according to claim 7,
The interference member is a rod supported on the back surface of the first slope so as to be changeable between a standing state and a falling state, and is configured to interfere with the lid only in the standing state. Therefore, for example, when the rod is set in the upright state when the rod is changed from the unfolded state to the retracted state, the lid is automatically opened and the lid is set in the collapsed state as in the above-described invention. The storage state is reached with the door closed. Therefore, when the occupant does not use the folding seat and directly mounts the wheelchair on which the occupant is seated, there is no need to perform the operation of showing the lid.

On the other hand, as shown in FIG. 5, a rectangular opening 26 is formed in the second slope 13 so as to face a region including the sheet striker 21 and the lid opening / closing rod 23 in a state where the slope is folded. I have. A seat striker storage lid 27 for opening and closing the opening 26 is pivotally supported by a hinge 28 at an edge of the opening 26 on the vehicle body side, as shown in FIG. The seat striker storage lid 27 is slightly larger than the opening 26 and is openable and closable above the upper surface of the second slope 13, and a plate 29 protrudes from the back surface as shown in FIG. . The plate 29 is provided so as to abut on the locked portion 23a of the lid opening / closing rod 23 in an upright state in an orthogonal state when the folding slope 7 shifts from the expanded state to the retracted state. The portion is provided with an engagement groove 29a for engaging with the locked portion 23a.

The drive unit 18 has a motor 33 fixed to a support member 32, as shown in FIG. The motor 33 is connected to a control circuit (not shown) and has a motor output shaft 33a. A spur gear 34 is meshed with the motor output shaft 33a. This spur gear 34
Output shaft 34a is gear-coupled to a first slope rotation center shaft 36 via a planetary gear reducer 35,
A slope rotation center shaft 36 is coupled in the vehicle width direction to a base end (a rear end in the retracted state and an end which is a distal end in the expanded state) of the first slope 12, and is supported by a support bracket 37. It is rotatably supported by the vehicle body.

In the embodiment having the above-described configuration, when the folding slope 1 drawn out of the cabin shown in FIG. 1 and deployed is stored in the cabin, a predetermined storage switch is operated. Then, the motor 33 rotates in a predetermined direction, and the first slope rotation center axis 36
At (clockwise arrow),
As shown in the drawing, the first slope 12 rotates counterclockwise about the first slope rotation center axis 36 as a rotation center b, and starts to rotate in a direction of rising while raising its tip end ( Arrow b). At the same time, the second slope 13 is driven via the slope link 14, and the second slope 13 rotates clockwise in the figure while displacing the base end thereof downward (arrow C). At the same time, the movable bumper member 16 is driven via the bumper link 17 and rotates clockwise about the support point with the vehicle body as the rotation center a (arrow C).

When the motor 33 continues to operate, the first slope rotation center shaft 36, the first slope 12, the second slope 13, and the movable bumper member 16 continue to rotate in the respective directions (arrows A, B, C). , D). Then, as shown in FIG. 1, the first slope 12 overlaps the upper surface of the inclined floor portion 10, the second slope 13 overlaps the back surface of the first slope 12, and the roller 30 is connected to the inclined guide. When the slope 31 is in the retracted state in contact with the upper end 31a of the distal end of the portion 31, the motor 33 automatically stops and the folding slope 1 is in the retracted state.

If the lid opening / closing rod 23 is previously operated in the upright state when shifting from the unfolded state to the stored state, as shown in FIG. When the back surface of the first slope 12 and the back surface of the second slope 13 approach each other, the locked portion 23 a of the lid opening / closing rod 23 and the engagement groove 29 a of the plate 29 are engaged. Therefore, when the storage state is further shifted to the storage state, as shown in FIGS. 1 and 12, the back surface of the first slope 12 and the back surface of the second slope 13 come closer to each other, so that the seat striker storage lid 27 is opened and closed. Rod 2
5 and the plate 29. Therefore, when the seat striker storage lid 27 is opened and the folding slope 1 is completely stored, as shown in FIG.
The seat striker storage lid 27 is fully opened with the seat striker storage lid 27 standing on the hinge 28.

When the seat striker storage lid 27 is fully opened, the opening 2 is provided on the second slope 13 side.
6, the sheet striker 21 is exposed.
Therefore, by expanding the third-row foldable seat 7 and engaging the lock 22 provided on the leg 7c thereof with the seat striker 21, the all-sheet set state C shown in FIG. 3 is easily formed. It is possible.

In the full seat setting state, the seat striker storage lid 27 is located below the third-row foldable sheet 7, so that even if the seat striker storage lid 27 is upright, it will not be a hindrance. There is no.

However, when the lid opening / closing rod 23 is previously operated in the collapsed state when shifting from the expanded state to the retracted state, the lid opening / closing rod 23 is operated in the above-described process.
Does not interfere with the plate 29 of the seat striker storage lid 27. Therefore, the seat striker storage lid 27 that has been closed in advance is not driven to open even when the state is shifted from the expanded state to the storage state, and the opening 26 is closed by the seat striker storage lid 27. Will be maintained.
Therefore, when forming the wheelchair riding state B in which the occupant travels while sitting on the wheelchair 2 shown in FIG. 2, if the lid opening / closing rod 23 is set to the falling state in advance, the seat striker storage lid 27 is unnecessarily opened. The opening 26 is kept closed by the seat striker storage lid 27.

The folding slope 1 in the stored state
When the vehicle is stored in the deployed state pulled out of the vehicle compartment, a predetermined deployment switch is operated. Then, the motor 33 rotates in the opposite direction to the above, and the first slope rotation center shaft 36 rotates clockwise in FIG.
As a result, as shown in FIG.
With the slope rotation center shaft 36 as the center of rotation b, it rotates clockwise, and starts to rotate in the direction in which it rises while raising its tip (to the arrow). At the same time, the second slope 13 is driven via the slope link 14, and while moving to the rear of the second slope 13 (arrow G), its tip is displaced upward and turned counterclockwise. Try to move (arrow H).

At this time, as shown in FIG. 14, in the initial stage of the deployment, the slope link 17 and the second slope 1
3 is in a state in which the inclination angle is large, a large torque is required to drive the second slope 13 in the counterclockwise direction (arrow H). However, the inclined guide portion 31 is formed at the distal end of the second slope 13, and the movable bumper 1 is mounted on the upper end 31a of the inclined guide portion 31.
The roller 30 fixed to 6 abuts. For this reason,
When the second slope 13 moves rearward in the vehicle body (in the direction indicated by the arrow G), the inclined guide portion 31 is pressed against the roller 30 to roll the roller 30, whereby the rear end of the second slope 13 is moved to the position shown in FIG. As shown in FIG.
Is guided obliquely upward along. Therefore, it is possible to shift from the stored state in which the second slope 13 is superimposed on the first slope 12 in the substantially horizontal state to the deployed state with a small torque.

When the motor 33 continues to operate, the first slope rotation center shaft 3 continues as shown in FIG.
6 and the first slope 12 are deployed in the clockwise direction (arrows E and F), and the second slope 13 is deployed while its tip is rotated in the counterclockwise direction. Then, after the shape becomes substantially rectangular as shown in FIG. 6 described above, the second slope 13 continues on the extension of the first slope 12, and the tip of the second slope 13 comes into contact with the ground. When a load is applied to the motor 33, the motor 33
Stops automatically. Thereby, the folding slope 1 is
The state reaches the slope development state A shown in FIG.

At the time of transition from the stored state to the deployed state, as shown in FIG. 13, the locked portion 23a of the lid opening / closing rod 23 is locked to the plate 29 of the seat striker storage lid 27 in the upright state. In this case, in contrast to the case where the state is shifted from the expanded state to the stored state, the state changes in the order of FIG. 13 → FIG. 12 → FIG. 1 → FIG. Therefore, the seat striker storage lid 27 automatically closes as the folding slope 1 changes from the stored state to the expanded state.
Therefore, when folding the third-row foldable sheet 7 from the all-sheets set state C to bring the folding slope 1 into the deployed state, it is not necessary to close the sheet striker storage lid 27 by manual operation, and quickly from the all-sheets set state C. , The folding slope 1 can be in the deployed state.

[0041]

As described above, according to the first aspect of the present invention, the first slope and the first slope are driven by the driving means.
The second slope is driven via the slope and the slope link, so that the folding slope can be changed between the retracted state and the expanded state. Therefore, there is no difficulty in using it, and a physically handicapped person or an elderly person can easily use it. Further, in the retracted state, the first slope falls down on the vehicle body floor, and the second slope moves in parallel to reach the first slope. Can be secured widely, and usability when the wheelchair is not mounted on a vehicle can be improved.

According to the second aspect of the present invention, the required driving torque can be obtained by using the small output motor, the slope can be driven at an appropriate speed, and the unit space can be minimized. Can be limited
This makes it possible to mount the wheelchair elevating device while suppressing a decrease in the cabin space.

According to the third aspect of the present invention, the guide surface comes into contact with the rollers at the beginning of the transition from the storage state to the development state, so that the movement in the starting direction is assisted, and the movement is smooth with little torque. Start is possible.

According to the fourth aspect of the present invention, since the folding seat is provided at the rear portion of the vehicle body, the folding seat can be expanded when the wheelchair is not mounted on the vehicle. In addition, since the first slope is provided with the sheet striker and the second slope is provided with an opening for exposing the sheet striker, the folding sheet is locked when the folding slope is folded and the folded sheet is deployed. Through the opening, the first slope can be engaged with the sheet striker, so that the folded sheet can be locked in the expanded state. Therefore, the folded sheet can be used in a stable state as needed while securing a necessary space for mounting the wheelchair on the vehicle.

According to the fifth aspect of the present invention, in the unfolded state, the opening can be closed by the lid so as to be in the non-open state, and the folding slope can be changed from the unfolded state to the retracted state. When the lid is opened, the striker for the sheet is exposed from the opening, so that the folding sheet can be locked quickly.

According to the sixth aspect of the invention, when the storage state is shifted from the storage state to the unfolded state, the lid is driven to close and the opening is closed. A safe slope without openings can be formed while allowing the use of a folded sheet.

In addition, according to the invention as set forth in claim 7, for example, when the rod is set in the upright state when the storage state is changed from the unfolded state, the lid body can be automatically set in the same manner as in the above-described invention. If it is opened and it is in a collapsed state, it reaches the storage state with the lid closed. Therefore, when the occupant directly mounts the wheelchair sitting on the vehicle without using the folding seat, it is not necessary to perform the operation of closing the lid, and it is possible to prevent the complexity of the operation beforehand and to improve the usability. it can.
