Description

[Detailed Description of the Invention] The present invention relates to a lift for allowing a person in a wheelchair to ascend and descend from an automobile.

Conventionally, when a person in a wheelchair was raised or lowered into a car using a lifter, there was a risk that the wheelchair would move during the lift and fall, causing anxiety in the elevator.

This invention prevents the risk of the wheelchair falling and eliminates anxiety by providing a fence on the side of the receiving plate on which the lifter's wheelchair is placed, and the fence can be removed when the lifter is stored inside the vehicle while driving. In the olden days, it was folded to make more space inside the car body.

The embodiments of the present invention will be described in detail below with reference to the following.

Also shown in Figures 1 to 5, 1 is the car body, 3 is the rear wheel, 5, 5 is a door that opens and closes the rear of the car body 1, 7.9 is the rear floor hK of the car body 1, and 1 end is Pivotally connected by shaft IL13,
A link 15 provided in parallel is a support pivotally connected to the other end of the link γ, 9 by shafts 17, 19.

Reference numeral 21 denotes a receiving plate pivotally attached to the lower end of the support body 15 by a shaft 23, and is engaged by a locking piece 25 to maintain a horizontal posture. It is configured to be rotatable.

The receiving plate 21 is divided into two parts pivotally connected to each other by a shaft 27, and is provided so as to be foldable about the shaft 27 when stored in the vehicle body 1.

Generally indicated, 29 is a fence provided on the side of the receiving plate 21 so as to protrude upward, and is constructed as follows.

That is, 31, 31 is a bracket 33 fixed to the side of the receiving plate 21, and 37, 39 is a column vertically attached to a support shaft 35 which is rotatably supported in the horizontal direction by a bracket 33. To the upper end button and middle part of the pillar 3L31,
It is a handrail that is firmly supported at both ends.

The handrail bar 37 is located at a position that is easy for a person to use while standing up (height of 80 cm), and the handrail bar 39 is located at a position that is easy to use when a person is sitting in a wheelchair 40 (height: 60 cm).
0 cm height).

Numeral 41 is a locking piece fixed to the receiving plate 21, and by inserting a pin 43, the support 31 is locked and the vertical posture is maintained.

Reference numeral 45 denotes a support fitting fixed to the rear end of the handrail bar 37, and is provided with a fitting hole penetrating in the vertical direction.

Reference numeral 47 is a rear handrail bar, with shaft parts 4 provided vertically at both ends.
9.49 are removably fitted into the fitting holes of the support fittings 45.45 on both sides.

51 is a collar fixed to the shaft portion 49.

Generally shown at 53 is an actuating device for swinging the links 7 and 9, and is constructed as shown below.

That is, 55 is a power unit containing a hydraulic pump (not shown) driven by a motor (not shown) operated by battery power, 57 is an operating valve that controls the hydraulic pressure generated by the power unit 55, and 59 is an operating valve. It is a cylinder that communicates with 57.

The cylinder 59 is attached to a bracket 61 fixed to the vehicle body 1.
One end is pivotally connected to the arm 62 by a shaft 62, and the other end is pivotally connected by a shaft 65 to an arm 63 which is fixed to the shaft 13 and rotates integrally with the link 9. , the link 9 is swung, and the receiving plate 21 is raised and lowered.

With the above configuration, in order to allow a person sitting in the wheelchair 40 to board the vehicle body 1 from the ground, the operation valve 57 is operated to contract the cylinder 59, and the link 9
The receiving plate 21 swings downward, and the receiving plate 21 descends while maintaining its horizontal direction, and stops at a position in contact with the ground.

Raise the fences 29 and 29 that were folded inward during storage vertically, lock them with the pins 43 and 43, and then move the wheelchair 40 onto the receiving plate 21.
Insert the shaft portions 49 at both ends into the fitting holes of the support fittings 45 and 45 on both sides.

Next, when the cylinder 59 is extended, the receiving plate 21 rises and stops at the same level as the floor of the vehicle body 1, as shown in FIG. 3, and the wheelchair 40 is moved into the vehicle body 1.

While the receiving plate 21 is rising, the person sitting in the wheelchair 40 relies on the handrail 39 to maintain stability.

To retract the receiving plate 21 while driving, remove the rear handrail bar 47 and move the fence 29.29 to the support shaft 35.3.
Close the middle part 5 and turn it inward to fold it, then,
The receiving plate 21 is folded around the shaft 27, and the entire receiving plate 21 is rotated upward around the shaft 23,
Figure 4 shows the fanning position.

When pushing the button on the wheelchair 40 from the vehicle body 1 to the ground, the operations can be performed in the reverse order as described above, so the explanation will be omitted here.

As described above, the present invention includes links that are pivotally connected at one end to the vehicle body and arranged in parallel so as to be able to swing vertically, a support body that is pivotally connected to the other end of the link, and a link that is horizontally attached to the support body. A lifter comprising: a receiving plate supported in the direction; a fence provided on the side of the receiving plate so as to protrude upward and be detachable or swingable; and an actuating device for swinging the link. Since this lifter can widen the space inside the vehicle body when stored inside the vehicle body, it can prevent the risk of falling when raising and lowering the wheelchair, and it also provides peace of mind for the person sitting in the wheelchair by holding on to the handrails of the fence. It gives a sense of comfort to the vehicle, and it can expand the space inside the vehicle when it is stored in the vehicle while driving.

In addition, FIG. 6 and FIG. 7 show other embodiments, and the fence 2
9 is detachably provided on the receiving plate 21.

That is, a collar 67 is fixed to the lower end of the support column 31, 31, and the lower end of the support column 31 is inserted into and supported by a fitting tube 69 provided on the side of the receiving plate 21.
