Description

[Detailed Description of the Invention] ■Industrial Application Field This invention relates to a vehicle getting on and off device, and more specifically, a vehicle installed in a vehicle so that a physically disabled person who uses a wheelchair can ride and drive the vehicle while in a wheelchair. This relates to a passenger boarding device.

■Conventional technology This is a conventional riding device for physically disabled people.

There is Japanese Unexamined Patent Publication No. 58-54954.

However, this device has the following drawbacks because the entire wheelchair is placed inside the vehicle.

That is, (a) When the wheelchair is stopped at the loading position on the platform, the hydraulic drive device built into the wheelchair is operated by operating the manual pump, and the platform abutting wheels to Plan 1 are lowered onto the platform. Therefore, it requires difficult operating means to align the platform with the wheelchair, and therefore cannot meet the need for quick boarding.

(b) If the lower part of the axle of the wheelchair is not pulled up to a position higher than the upper edge of the door threshold, and the foot 1-rest is pulled up to the upper position of the platform, the wheelchair will collide with the platform when it turns. This operation is essential, and as in (a) above, it does not meet the need to get on the vehicle in a hurry.

Furthermore, (c) since the platform is rotated manually, it is impossible or extremely difficult for an occupant seated on the Plan I platform in a wheelchair to rotate the platform without an attendant.

In addition, (d) When the platform stops at the wheelchair loading position, the vertical height of the platform will be determined by the tire pressure, weight of the loaded object, etc. If the overall height of the vehicle is high, the platform will be at a high position, and if it is low, the platform will be at a low position. It will become a prominent position. Therefore, the adjustment allowance for the vertical height of the wheelchair itself will also differ each time the user gets on the wheelchair.

(Objective of the Invention) In view of the prior art, the present invention has an object to make it possible to quickly get into a car and to eliminate the need for fine adjustment of the platform.

(Long) Structure of the Invention In order to achieve the above object, the present invention provides a lifter having an arm provided on the floor of a vehicle that rotates between a position outside the vehicle and a driver's seat and moves up and down.

On the other hand, the seat 3 is composed of a sea I-back 38 and a sea cushion 41 having a slider 39 and a slider support frame 40 at the bottom. Then, the slider support frame 40 is placed on the seat support frame 31 and fixed with cotton screws 42 to assemble the wheelchair. Furthermore, locking pins 43 are installed on both sides of the slider support frame 40, as shown in FIG. A positioning arm 44 is provided.

Next, the action will be explained.

A description will be given of the process until the physically disabled person M in the wheelchair 30 is seated in the driver's seat of the automobile 1.

A pair of seat pedestals 18.18 are provided at the position of the driver's seat on the floor 2 of the automobile 1.
Seat support stand 1 provided at the tip of arm 8 between 18
6 are arranged as shown in FIG.

Then, the physically disabled person M in the wheelchair 30 opens the front door FD and the sliding door SD, and while riding in the wheelchair 30, picks up the switch box 54 that is within reach inside the vehicle and holds it in his hand to operate the vertical movement. Operate switch 55 so that arm 8 rotates upward.

At this time, the cover 5 provided on the seat support base 16
2 to cover the magnetic proximity switch 50 and leave the magnetic proximity switch 50 in the operating state. When the magnetic proximity switch 50 is operated, the vertical movement operation switch 55 and the rotation operation switch 56 are set to an operable state.

When the vertical movement operation switch 55 is operated to rotate the arm 8 upward, the motor 12 rotates and the hydraulic pump 1
1 is driven, and the cylinder part 10 of the vertical hydraulic cylinder 10
Oil flows into one end of the cylinder rod 10
b moves forward and rotates the arm 8 upward. As the arm 8 moves upward, the seats 1 to 16 also move upward. Then, when the arm 8 moves upward to a predetermined upper limit position, the vertical movement operation switch 55 is stopped to stop the upward movement of the arm 8.

Next, the turning operation switch 56 is operated so that the arm 8 turns to the right from the driver's seat position to a position outside the vehicle.

When the rotation operation switch 56 is operated to rotate the arm 8 to the right, the motor 12 rotates again and the hydraulic pump 11
is driven, and at this time a hydraulic circuit (not shown) is switched, oil flows into one end of the cylinder portion 9a of the horizontal hydraulic cylinder, the cylinder rod 9b advances, and the arm support member to which the arm 8 is pivotally attached is moved. 7 rotates clockwise, and arm 8 rotates clockwise.

Then, when the arm support member 7, that is, the arm 8 has turned to the right by 110 degrees to a predetermined right turning position, the operation of the turning operation switch 56 is stopped, and the right turning of the arm 8 is stopped. In this way, the seat support base 16 provided at the tip of the arm 8 is moved from the driver's seat position to the outside position of the vehicle, as shown in FIG.

After the seat support base 16 has been moved to the outside position of the vehicle, the second immovable operation switch 55 is operated again so that the arm 8 moves downward from the upper position to the lower position. When the vertical excitation operation switch 55 is operated to move the arm 8 downward,
The motor 12 rotates to drive the hydraulic pump 11, and this time oil flows into the other end of the cylinder portion 10a of the vertical cylinder 10, causing the cylinder rod 10b to retract and rotate the arm 8 downward. Then, when the arm 8 moves down and the seat support base 16 provided on the arm 8 moves down to a predetermined lower limit position where it can receive the seat 3 of the wheelchair 30, as shown in FIG. Stop the operation of 55 and stop the arm 8 from moving.

At this time, the lower limit position of the seat support base 16 is
The height is slightly lower than the bottom surface of the seat 3.

When the seat support base 16 is set to the lower limit position outside the vehicle, the cover 52 is removed from the stopper 52a and rotated so as not to cover the magnetic proximity switch 50, and the magnetic proximity switch 50 is put into the inactive state and moved up and down. The operation switch 55 and the rotation operation switch 56 are set to an inoperable state in which they do not operate even if the operation switch 55 and the rotation operation switch 56 are operated, so that the seat support base 16 is prevented from moving unexpectedly.

Thereafter, as shown in FIG. 10, the physically disabled person M in the wheelchair 30 operates the operating ring 33 to move the wheelchair 30 onto the seat support 16 so that the bottom of the seat 3 is facing backwards. Move it so that it is directly above you. Then, when the slider support frame 40 of the seat 3 is positioned directly above the seat support base 16, the magnet 51 provided at the rear of the seat 3 moves toward the magnetic proximity switch 50 as shown in FIG.
, and operate the magnetic proximity switch 50. Due to the operation of the magnetic proximity switch 50, the vertical movement operation switch 55
and the turning operation switch 56 are set to the operable state again.

Next, after loosening the locking screws 42 of the wheelchair 30 and setting the seat 3 or 1 so that it can be removed from the support frame 31, the vertical movement operation switch 55 is turned so that the arm 8 moves upward from the lower limit position to the 1st limit position. Move arm 8 upward. When arm 8 moves up a little, the
- The support stand 16 moves 1" to lift the slider support frame 40 of Sea 1 to Sea 3 and remove Sea 1-3 from the Sea 1-support frame 31. At this time, the positioning arm 44 provided at the rear of the slider support frame 40 fits between the boom 15 and the locking protrusion 16a provided at the end of the seat support base 16 on the boom 15 side, and the seat 3 is supported while being positioned at a predetermined position on the seat support base 16.

Therefore, as will be described later, even if the seat support base 16 moves, the seat 3 will not slip off the seat support base 16.

After that, as shown in FIG.
6, remove the seat support frame 31 from the position directly below the seats 1 to 16, and remove the axle 34, armrest 35, footrest 37, and casters 36 from the seat support frame 31. The wheelchair 30 is disassembled and these parts are stored inside the vehicle. After storing the parts, operate the vertical movement operation switch 55 again to move the arm 8 upward. When the arm 8 has moved up to the predetermined upper limit position, stop operating the vertical movement operation switch 55 and move the arm 8 upward. Stop the upward motion.

Next, the turning operation switch 56 is operated to turn the arm 8 to the left from the position outside the vehicle to the driver's seat position.

When the swing operation switch 56 is operated to swing the arm 8 to the left, the motor 12 rotates again, the hydraulic pump 11 is driven, and oil flows into the other end of the cylinder portion 9a of the horizontal hydraulic cylinder 9. The cylinder rod 9b is retracted, the arm support member 7 to which the arm 8 is pivoted rotates to the left, and the arm 8 turns to the left.

When the arm supporting member 7, that is, the arm 8, has turned to the left to a predetermined left turning position, that is, to the driver's seat position rotated 110 degrees, the operation of the turning operation switch 56 is stopped, and the arm 8 is turned to the left.
stop turning left. At this time, the arm 8 is at a predetermined upper limit position.

In this way, when the seats 1-3 are placed outside the vehicle and the seats 1 to 16 are rotated to the left and the 'M transposition position is set, the vertical movement operation switch 55 is moved to the arm 8, that is, the seat support ] 6 remains stationary from the upper limit position to the seating position, and the seat support base 16 is moved downward. sea 1
- The support base 16 moves downward while moving slightly forward of the vehicle to a predetermined seating position, and the slider support frame 40 of the seats 1 to 3 is attached to a pair of seat pedestals 18 and 18 provided on the floor 2.
When the vertical movement operation switch 55 is stopped operating the vertical movement operation switch 55, the downward movement of the seat support base 16 is stopped. At this time, the seat support base 16 is located between the pair of seats 18 and 18, and the slider support frame 40 of the seat 3 is placed on the seats 18 and 18. The front end of the slider support frame 40 is locked to the seat 1 locking piece 20 provided at the front end of the seat holder 18 located at the center of the floor 2, but the rear end of the slider support frame 40 is not locked.

Therefore, there is a risk that the seat 3 will move toward the rear of the vehicle.

Therefore, by operating the operating lever 26, the locking hook 22 is rotated toward the front of the vehicle, and the locking pins 43 protruding from both rear ends of the slider support frame 1140 as shown in FIGS. 3 and 13. The seat 3 is fixed in the driving position so as to prevent movement of the vehicle in the longitudinal direction. Further, movement in the width direction of the vehicle at the driver's seat position of Sea 1 to Sea 3 is performed by the seat stopper piece 20 and remains at Jc. Therefore, the physically disabled person sitting in seats 1-3 in the driver's seat position? ffM
can be driven with peace of mind.

In the above, physically disabled person M in wheelchair 30 is in car 1.
Although the steps up to sitting in the driver's seat have been described above, when getting into the wheelchair 30 from the car, the steps can be reversed to those described above.

■Effects As explained above, the present invention has a structure in which a lifter having an arm that pivots between a position outside the vehicle and a position of the driver's seat and that moves up and down is disposed on the floor of the vehicle. Since the seat 1~ support stand that supports the seat is provided at the tip of the arm, by preparing a removable wheelchair, the seat 1~ can be placed directly above the seat support stand located outside the vehicle. Move the wheelchair so that the bottom side is facing Sea 1, then move the arm slightly upward to remove the seat on which the physically disabled person is sitting from the wheelchair and support it on the seat support base, and then move the arm to the outside position of the vehicle. The wheelchair seat can be set as the driver's seat by moving it up, rotating it to the driver's seat position, and lowering it from the driver's seat position to the seating position.
