However, in the above-mentioned method, in the case of (a), wheelchairs are now made to order according to physique. If you use a car that is not very high in the cabin, your head can be stuck on the ceiling, or there is almost no clearance with the ceiling, and you may hit your head by vertical movement of the car body. In addition, when a person with a bad experience rides, a caregiver other than the driver is indispensable, which causes a further hindrance to going out. In addition, the cost of mounting the lift is expensive, so it cannot be replaced with another car and must be discarded together with the car. In case of (b) Getting on and off the seat requires human power or another lift. Seat remodeling costs are high. In the case of (c), depending on the weight, it is not possible alone, and there is a risk that the caregiver may injure the lower back.

Accordingly, there has been a demand for an invention of a lift which is inexpensive, can be operated lightly and easily even if the caregiver is a woman, and enables a disabled or elderly person to get on and off a standard car or standard seat of a van. .

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and a commercially available roof carrier is mounted on a standard passenger car or van, and the lift is fixed thereto. This lift comprises an arm holder portion detachably engaged with a roof carrier of an automobile, and an arm portion with an electric motor driven lifting device slidably held in the arm holder portion. The arm holder section,
It has the shape of a rectangular cylinder, one end of which is rotatably mounted on the roof carrier side edge of the driver's seat side around a vertical axis, and the rolling of a caster mounted on the other end,
The arm can be rotated on a flat plate laid in the front-rear direction on the passenger-side roof carrier, and the arm portion can be positioned near the passenger seat or the rear seat door. In addition, the arm portion is cylindrical, and a first roller bearing is provided at an end opposite to the projecting side of the arm portion so as to slidably hold the inside of the rectangular arm holder portion. Install the second roller bearing. By these two roller bearings, the arm slides smoothly in the arm holder. The first roller bearing includes:
The arm is rotatable 360 degrees with respect to the arm holder axis, but is mounted so that it rotates only in the sliding direction and does not rotate with respect to the holder axis. As a result, the arm section is moved to the arm holder section by about 90 to the arm holder axis.
It can be swung up and stored and locked to a holder fixed to a flat plate. In addition, the electric motor driven lifting device locked to one end of the second arm raises and lowers the sling sheet hung on the opposite end of the second arm, and lifts and lowers the cared person to provide a care vehicle such as a wheelchair and a passenger car. You can easily take care of getting on and off between.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1, FIG. 2 and FIG. 3 show an embodiment of the present invention.

First, the construction will be described. A commercially available roof carrier 1 is fixed to a roof of a vehicle body. Bar 2 as standard
Although it is composed of books, it is 3 to 3 depending on the weight of the cared person.
Maintain four mounting strength. Also, one assist bar 9 is locked in the front-rear direction at the driver seat side edge, and a flat plate 1 is provided at the passenger seat side edge.
Lock 0.

The arm holder 2 is rotatably locked to an assist bar 9 at an end 7 opposite to the side where the arm projects, and is supported on a caster 8 fixed to the side where the arm projects, and is urged on a flat plate 10. I do. Thus, the arm portion can be located near the passenger seat and the rear seat door. As shown in FIG.

The arm portion includes a first arm 3a and a second arm 3b. A first roller bearing 13 attached to the end of the first arm 3a and a second roller bearing attached to the projecting side of the arm holder 2. 12 and slide freely. The second arm 3b is locked to the first arm 3a by a fixing pin 14, and the fixing pins 15, 16
Then, the care receiver riding on the sling sheet 6 hooked on the hook 5 is moved up and down by the expansion and contraction of the electric motor driven lifting device 4 locked to the first arm 3a.

[0011] Therefore, the care receiver is provided with the sling sheet 6.
In a wheelchair or the like, a passenger is guided to the vicinity of the passenger seat or rear seat door opening, the sling sheet 6 is hooked on the hook 5, the electric motor driven lifting device 4 is operated, the hook 5 side of the second arm 3b is raised, and Let go. Next, the arm portion is slid in the vehicle body direction, and the cared person is put in the vehicle interior. After that, the electric motor drive lifting device 4 is operated to lower the hook 5 side of the second arm 3b to be seated on the seat.

Conversely, when the cared person is to be transferred from a passenger car to a wheelchair or the like, the reverse operation to the above-described riding method may be performed.

The roller bearing 13 attached to the end of the first arm 3a has a structure in which the arm can freely rotate 360 degrees with respect to the arm holder axis and slides only with respect to the arm holder but does not rotate. I have. Thus, when not in use, the arm portion is swung up by about 90 degrees with respect to the arm holder shaft, retracted, and locked by the holder 11 fixed to the flat plate.

[0014]

As described above, the present invention has a simple structure, and the care receiver can easily get on and off the seat of the passenger car with a small amount of labor.
