Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lift used for raising and lowering a wheelchair and the like.

[0002]

2. Description of the Related Art FIGS. 6 to 9 show a conventional lift. FIG.
As shown in FIG. 1, a lift 3 for raising and lowering a wheelchair or the like is provided in the opening 2 of the vehicle 1. The lift 3 includes a platform 5, a link mechanism 6 connected to the platform 5, a driving mechanism 7 for moving the link mechanism 6,
And a main body 8 for storing the platform 5.

[0003] In such a conventional lift, the wheelchair 4 is placed on the platform 5 with the platform 5 in contact with the ground, as shown in FIG. When the wheelchair 4 is placed on the platform 5 as described above, the link mechanism 6 is moved by the drive mechanism 7 to lift the platform 5 vertically as shown in FIG. Once the platform 5 has been raised to the top, it is now moved horizontally and the wheelchair 4 is stored together with the platform 5 in the vehicle 1. Contrary to the above, wheelchair 4 stored in vehicle 1
Is lowered on the ground, first, the platform 5 is horizontally moved to the position shown in FIG. Thereafter, the platform is lowered vertically.

[0004] As described above, the platform 5 is moved up and down or moved back and forth in the horizontal direction while the wheelchair is placed on the lift. In order to prevent the wheelchair from falling off the platform 5 during the movement of the platform 5, there is a type provided with a mechanism for fixing the wheel of the wheelchair on the platform 5. But,
If you are in a wheelchair,
I feel uneasy that my wheelchair may fall from the platform 5. Therefore, as shown in FIG. 9, there is a platform in which handrails 9 and 9 are attached to both sides of the platform 5. These handrails 9 are fixed to side plates 10, 10 erected on both sides of the platform 5.

[0005]

On the other hand, a vehicle provided with the above-described lift 3 is used by mounting a rear seat on the platform 5 when the lift 3 is not used. However, as shown in FIG. 8, if the handrails 9, 9 are erected at both ends of the platform 5, they hinder the mounting of the rear seat. Therefore, when the lift 3 is not used, the handrails 9 are removed from the side plates 10 and 8. The removed handrail had to be pushed under the rear seats and lowered from the vehicle.

[0006] However, the handrails 9, 9 pushed under the rear seat jump out under the feet of a person sitting on the rear seat while the vehicle is running, and become obstructed, or under the rear seat, left and right. To make noises. In addition, if the handrail 9 is removed from the vehicle, there is an inconvenience that the handrail 9 cannot be used when it is necessary to suddenly mount a wheelchair. SUMMARY OF THE INVENTION It is an object of the present invention to provide a lift that can use a handrail whenever necessary, and that does not interfere with the handrail when not in use.

[0007]

According to a first aspect of the present invention, a main body provided on a floor of a vehicle, a platform, and the platform are moved from an opening of the vehicle to the outside of the vehicle while keeping the horizontal state of the platform. In a lift equipped with a moving mechanism, on both sides in the width direction of the platform, a side plate that stands upright on the platform, and a handrail including a grip portion and a leg portion, and a lower leg portion of the handrail,
A fixing mechanism is attached to a platform surface inside the side plate via a rotating mechanism, and when the leg of the handrail stands upright on the platform, the fixing mechanism fixes the leg and the side plate. In addition, when the railing is dropped on a platform, the whole railing is characterized in that it is dimensioned to fit between both side plates.

[0008] The second invention is characterized in that the rotating mechanism is detachable from the platform.

[0009]

1 to 5 show an embodiment of the present invention. FIG. 1 shows a part of a lift 11 according to the embodiment. This lift 11 is the same as the conventional lift 3 shown in FIGS. 6 to 9 except for a structure for attaching a handrail 12. Therefore, the same components as those in the conventional example will be described using the same reference numerals. Also, regarding the operation of the lift 11,
Since it is the same as the lift 3 of the conventional example, its description is omitted.
That is, in this embodiment, the link mechanism 6 and the drive mechanism 7 constitute a platform moving mechanism of the present invention.

As shown in FIG. 1, the handrail 12 includes a grip portion 12a and a leg portion 12b. And the leg 12b
Is erected along the side plate 10. Reference numeral 13 in the figure is a slope plate provided so that the wheelchair can be smoothly moved up and down to the platform 5 and can be put out of the platform 5 only when used.

Further, as shown in FIG.
The plate 14 is fixed to the lower end of the
Is attached to the platform 5 via the hinge 15. That is, one rotating piece 15 a of the hinge 15 is connected to the plate 14, and the other rotating piece 15 b is attached to the platform 5 via the hinge attachment plate 16. The hinge 15 is a rotation mechanism of the present invention. Further, the rotary piece 15b side is attached and detachable by a bolt 17 and a nut 18.

As described above, since the leg portion 12b of the handrail 12 is attached to the hinge 15, the handrail 12 can be tilted toward the platform 5. Further, as shown in FIG. 2, in a state where the leg 12b is
A through-hole 20 penetrating these three members is formed in a portion where the b, the plate 14 and the side plate 10 overlap. When the leg 12b stands up, a handle screw 21 is inserted into the through hole 20, and a nut 2
2 and tighten the plate 14 and the leg 12b,
The side plate 10 and the side plate 10 are integrated. That is, the handle screw 21 and the nut 22 are the fixing mechanism of the present invention.

FIG. 2 is a diagram showing a mounting structure of the handrail 12 mounted on the left side in the traveling direction when the wheelchair gets on the platform 5. However, if the rotating piece 15b of the hinge 15 attached to the left end is rotated by 180 degrees, the other part can be attached to the right end of the platform 5 while keeping the other parts as they are. That is, since the same component can handle both the left and right handrails, the manufacturing cost can be reduced as compared to using separate left and right components.

With the above construction, if the left and right handrails 12 are vertically erected on the platform 5 and fixed with the handle screws 21, respectively, FIG.
As shown in (b), a railing 1 is provided on both sides of the platform 5.
2 can be set. In addition, this platform 5
When the wheelchair is not placed on top, the handle screw 21
Can be removed and the handrail 12 can be dropped on the platform 5. FIGS. 4A and 4B show the above handrail 1
FIG. 5 (a) and FIG. 5 (b)
Is in a completely defeated state. As shown in FIGS. 5 (a) and 5 (b), the handrails 12 on both sides are dimensioned to completely fit in the small side plates 10, 10 in a completely folded state.

As described above, since the handrail 12 fits between the side plates 10, 10, the handrail 12 does not interfere with the rear seat when it is mounted thereon. Further, unlike the case where the handrail is removed, the removed handrail does not pop out while the vehicle is running, and the handrail 12 can be raised and used whenever necessary.

Further, with the handle screw 21 removed, a bolt 18 attached to the platform 5 is provided.
By removing the nut, the handrail 12 can be removed from the platform 5. For example, if a user of a wheelchair has difficulty with one hand, it is meaningless to attach the handrail 12 to that side. The handrail of this embodiment can be easily attached and detached by the bolt 18 and the nut 19,
Can be attached only to those who need it. However, the handrail 12 does not have to be detachable, so that the side plate 1
If it can be beaten between 0 and 10, there is enough merit.

[0017]

According to the first aspect of the present invention, when not using the lift, the handrail can be tilted so as not to be obstructed. Therefore, when not in use, there is no problem with the location of the handrail, and the handrail does not move in the vehicle and hinders or generates noise. According to the second aspect, only a necessary handrail can be attached.
