Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wheelchair mounting device for a vehicle.

When a disabled person using a wheelchair gets into a car, he or she must move from the wheelchair to the driver's seat of the car, sit down, fold the wheelchair, lift it up, and place it on the passenger seat or rear seat. The wheelchair must be lifted from inside the vehicle, lowered to the ground, and reassembled before transfer.

Loading and unloading a wheelchair by hand while seated in the driver's seat as described above not only requires a lot of physical strength and is extremely difficult for people with weak physical strength, such as women. When the chair is seated, the wheelchair must pass over the occupant's knees, so the wheels of the wheelchair touch the occupant's clothes.
There are also problems such as staining clothes with mud and the like.

Therefore, for example, although there is a technique described in Japanese Patent Publication No. 48-26336 that allows a cassette for storing a wheelchair to be easily loaded and unloaded from the vehicle body via a torsion spring device, The cassette is rotated and unloaded on the outside of the cassette, and the cassette is rotated against the torsion spring device.
Since it is only supported by a book rod, loading and unloading of a heavy wheelchair becomes extremely unstable. Furthermore, there is a risk that the rod will be subjected to excessive bending or torsional load stress and breakage, which increases the risk and makes it difficult to put it into practical use.

Furthermore, since the torsion spring device is disposed on the side of the vehicle body, visibility for the occupants is deteriorated and application to a four-door type vehicle is difficult.

The present invention addresses the above-mentioned problems and aims to provide a loading device that can safely and extremely easily load and unload wheelchairs without using human power. I will explain about it.

1 to 3, reference numeral 1 denotes the roof of an automobile. A base 2 is fixed on the roof 1, and one side (the end on the passenger seat side) of the base 2 has a C-shaped channel member, for example. A driving equipment mounting board 3 made of the following is fixed in the front-rear direction.

One end of a first rail 4 is rotatably attached to the member on the other side of the base 2, that is, the driver's seat side, with a shaft 41, and the base end of the first rail 4 is attached to the drive equipment mounting board. The tip of the gas stay 7 that is pivoted to the gas stay 7 is pivoted to the gas stay 7, and the gas stay 7 is pivoted to rotate upwardly about the shaft 41 from the horizontal state shown in FIG. 3 to the tilted state as shown in FIGS. 1 and 2. has been done.

5 is a second rail, and the second rail 5 is connected to the first rail 4 via a first link mechanism 8, which will be described later, so that it can slide and rotate in the longitudinal direction, that is, in the width direction of the vehicle body.

Reference numeral 6 denotes a third rail, and the third rail 6 is connected to the second rail 5 via a second link mechanism 9, which will be described later, so that it can slide and rotate in the longitudinal direction, that is, in the width direction of the vehicle body.

The first rail 4 and the third rail 6 are composed of C-shaped channel members, as shown in FIG.
The second rail 5 has a structure in which a C-shaped channel member 5b is coupled and fixed to the lower surface of the square cross-section member 5a, and when all the rails 4, 5, and 6 are horizontally overlapped, the second rail 5 has a square cross-section member 5a. The mold cross-section member 5a fits into the third rail 6, and the C-shaped channel member 5b fits into the first rail 4, so that the thickness in the vertical direction when the rails are overlapped can be reduced. It's summery.

The first link mechanism 8 is connected to the first link mechanism 8 as shown in FIG.
A fixed roller 81 is attached to the end of the rail 4 on the driver's seat side, that is, the end on the side where the shaft is attached to the base 2, and is fitted into the C-shaped channel member 5b of the second rail 5; A link member 84 is pivotally connected to the link member 84, and the roller 82 fitted in the C-shaped channel member 5b of the second rail 5 is rotatably attached to the other end of the link member 84.
One end is pivotally connected to the shaft of the roller 82, and a first
It is composed of a link member 85 to which a roller 83 fitted in the rail 4 is rotatably attached.

As shown in FIG. 5, the second link mechanism 9 also includes a fixed roller 91 attached to the driver's seat side end of the second rail 5 and fitted in the third rail 6, like the first link mechanism. A roller 92 whose one end is pivotally connected to the shaft of the roller 91 and whose other end is fitted into the third rail 6.
a link member 94 rotatably attached to the roller 92, and a link rotatably attached at one end to the shaft of the roller 92 and at the other end a roller 93 fitted in the square cross-sectional member 5a of the second rail 5. 95.

The drive device mounting board 3 includes a drive source 10 such as an electric motor and a drum 1 rotated by the drive source 10.
A wire rope 13 wound around the drum 11 is attached to a winch 12 consisting of a first type winch 12, and a wire rope 13 wound around the drum 11. 15, and its tip is coupled and fixed to the upper surface of the passenger side end of the third rail 6.

Further, a lock device 16 and a lock release solenoid 17 are attached to the driving equipment mounting board 3, and the lock device 16 is attached to the passenger side end of the second rail 5.
A striker 18 that engages is fixed.

A locking mechanism 19 for locking the folded wheelchair A is provided on the upper surface of the third rail 6.

A top cover 20 is provided at the front and rear ends of the driving equipment mounting board 3.
is rotatably attached, guide rails 21, 21 are attached to the inner side of the front and rear surfaces of the upper lid 20, and guide rollers 23, 23 provided at the tip of an arm 22 fixed to the first rail 4 are attached to the guide rail 2.
As shown in FIG. 6, when the first rail 4 is in a horizontal state, the top cover 20 is closed, and when the first rail 4 rotates upward, the guide The rollers 23, 23 rotate within the guide rails 21, 21 to rotate the top cover 20 upward, thereby widening the side surface on the driver's seat side.

In the above configuration, when the winch 12 is winding the wire rope 13, the first link mechanisms 8 and 9 are connected to the respective link members 84 and 85.
94 and 95 are substantially in a straight line, and the first, second, and third rails 4, 5, and 6 are in an overlapping state, that is, a stored state, as shown in the third figure, and the striker 18 is attached to the locking device 16. is engaged.

In this retracted state, the gas stay 7 is compressed and its reaction force is supported by the engagement of the lock device 16 and the striker 18. The upper lid 20 is also in a closed state.

When the user transfers from the wheelchair to the driver's seat and operates a switch (not shown) provided near the driver's seat, the solenoid 17 is activated to unlock the lock device 16 and disengage the striker 18.

Then, the gas stay 7 extends and rotates the first rail 4 upward about the shaft 41, and as the first rail 4 rotates, the upper lid 20 opens.

When the first rail 4 rotates upward, the second rail 5 and the third rail 6 overlapping it also tilt, and the second rail 5 rotates between the fixed roller 81 and the roller 8.
The fixed roller 81 slides against the first rail 4 and protrudes to the side while rolling the fixed roller 81 against the second rail 5.
When the second rail 5 relatively passes through the midpoint (i.e., the center of gravity position in the longitudinal direction), the second rail 5 rotates downward about the fixed roller 81, and the link member 85 rotates at the joint with the link member 84, that is, the center of gravity of the roller 82. The rollers 83 roll as they rise, and when the rollers 83 hit the stopper 24 provided in the first rail 4 and are restrained from further rolling, the second rail 5 moves to the position shown in the second figure. It hangs down at a steep slope along the upper part of the side wall of the vehicle.

Similarly to the second rail 5, the third rail 6 also slides laterally with respect to the second rail 5 while rolling the fixed rollers 91 and rollers 92 of the second link mechanism 9,
and rotates downward around the fixed roller 91,
The slit 25 provided in the second rail 5 by the roller 93
When the third rail 6 reaches the end thereof and is restrained from further rolling, the third rail 6 is held in a substantially vertical position close to the door opening as shown in the second figure.

In the above operation, the third rail 6 slides and rotates while pulling out the wire rope 13 from the winch 12.
No rapid sliding or rotation occurs due to the pullout load of No. 3, and the rails move slowly from the second rail 5 to the third rail 6 in an almost orderly manner.

In the state shown in FIG. 2, as described above, the third rail 6 is held almost vertically in the immediate vicinity of the door opening, so that the folded wheelchair A can be easily moved to the third rail while seated in the driver's seat. 6 locking mechanism 19
It can be locked to.

After the wheelchair A is locked to the third rail 6 by the locking mechanism 19, when a switch (not shown) provided near the driver's seat is operated, the drive source 10 rotates, rotates the drum 11, and connects the wire rope 13. Get involved.

Then, the third rail 6 rotates while being pulled up, and both link members 94 and 95 of the second link mechanism 9
are almost in a straight line, and the third rail 6 overlaps the second rail 5, and then the second rail 5 and the third rail 6 overlap.
are pulled up and rotated while still overlapped, and the
Both link members 84 and 85 of the link mechanism 8 are aligned almost in a straight line and overlapped on the first rail 4, and the wire rope 13 is further wound around the first rail 4.
The rail 4 returns to the horizontal state while contracting the gas stay 7 while overlapping the second and third rails 5 and 6, and the striker 18 provided on the second rail 5 engages with the locking device 16 and the drive source 10 operation will stop.

The upper lid 20 is closed by the downward rotation of the first rail 4, and when the drive source 10 stops, the folded wheelchair A is placed and fixed on the roof as shown in the third figure, and the upper lid is placed above it. 20, the wheelchair is in a stored state.

In the above wheelchair storage operation, the wire rope 13
is locked to the base end of the third rail 6, and the third
Since a wheelchair with considerable weight is secured to the tip of the rail 6, when the wire rope 13 is wound in, the third rail 6 first overlaps the second rail, and then the second rail 5 moves. Initially, the second rail 5 overlaps the first rail 4, and then the first rail 4 begins to rotate, and so on, and so on.

To get off the vehicle, operate the switch from inside the vehicle as described above, and the solenoid 17 will operate to unlock the locking device, disengage the striker 18, and extend the gas stay 7 to open the first rail 4. rotates, and the second rail 5 and third rail 6 sequentially slide and rotate to reach the state shown in the second figure, making it possible to remove and assemble the wheelchair A extremely easily.

In the illustrated embodiment, each of the first, second, and third rails is one, and although this has the advantage of reducing the weight of the device, the number of each rail is can be arbitrarily selected as necessary.

As described above, according to the present invention, the wheelchair is loaded onto the vehicle roof by rotating and sliding the three rails using the winding force of the pulling mechanism and the stretching force of the pushing up mechanism. Since it is stored or unloaded at a position near the side of the vehicle body, the loading and unloading work can be performed stably and reliably, and can be performed extremely simply and easily, and sufficient safety can be obtained. Moreover, each rail and the wheelchair can be supported reliably and stably on the vehicle roof by the lock mechanism.

In addition, the wheelchair does not take up space inside the vehicle, and since there are no structures on the sides of the vehicle, the passenger's view is not obstructed. Of course 4
It can also be applied to door-type vehicles.

It should be noted that the device of the present invention can be used not only for wheelchairs but also for loading and storing walking machines for handicapped people, and can also be used as a loading and storing device for luggage when used by people other than handicapped people. It is.
