Problems solved by technology

Although the above method is taken into consideration, the use of a high-capacity actuating oil pump will increase the cost
[0007] In addition, lifting and moving the load-bearing part that supports the wheelchair at a relatively fast speed may also cause the wheelchair user to be unable to ride with peace of mind.
[0008] When descending and moving the loading part that does not support the wheelchair at a faster speed,

Embodiment Construction

[0104] Hereinafter, embodiments of the vehicle lifting device according to the present invention will be described with reference to the drawings.

[0105] Such as figure 1 and figure 2 As shown, the lifting device L for a vehicle is at the rear of a vehicle V. The vehicle V is, for example, a recreational vehicle, and has a rear door D for opening and closing an opening O at the rear.

[0106] The lifting device L for a vehicle includes a plate-shaped loading portion 1 for carrying the wheelchair C, a lifting frame 2 supporting the loading portion 1 so as to be slidable in and out of the vehicle, a pair of left and right arms 3 whose lower ends are connected to the lifting frame 2, and The arm 3 is connected to a pair of elevating link mechanisms 4 on the left and right sides of the vehicle V (refer to image 3 ), drive and operate the left and right pairs of lifting connection mechanisms 4 to lift and move the left and right pairs of hydraulic cylinders 5 of the bearing p...

Abstract

The invention provides a vehicular elevating device which can reduce wheelchair transfering time with a low cost and properly transfer wheelchairs. An oil-pressure cylinder 5 formed by a double-action single-rod type cylinder is made to extend so as to elevate a bearing part 1 or made to be shortened so as to lower the bearing part 1. Actuating oil from an actuating oil pump 33 and actuatin goil discharged by a first cylinder chamber 34 are supplied to a second cylinder chamber 35 to make the bearing part move upwards in an accelerating manner. The pressure of the actuating oil supplied to the second cylinder chamber 35 is set above the pressure required by the upward movement of the bearing part 1 bearing no wheelchairs and below the pressure required by the upward movement of the bearing part 1 bearing wheelchairs.

Description

technical field [0001] The present invention relates to a lifting device for a vehicle, wherein the load-bearing part supporting the wheelchair is raised and moved corresponding to the floor of the vehicle to a set raised position through the extension of the hydraulic cylinder, and the load-bearing part is further corresponding to the ground through the shortening of the hydraulic cylinder. Descending moves to the set descending position. Background technique [0002] The lifting device for vehicles lifts the bearing part to the raised position by extending the hydraulic cylinder, and lowers the bearing part to the lowered position by shortening the hydraulic cylinder, so that the wheelchair can move between the ground and the interior of the vehicle. [0003] On the other hand, in such a lift device for a vehicle, conventionally, a double-action single-rod type, that is, a hydraulic cylinder is formed in such a manner that the rod is provided on only one side with respect ...
