Description

  The present invention relates to a wheelchair lifting device, and more particularly to a wheelchair lifting device that can lift and mount a wheelchair outside the vehicle and store it in the vehicle, and store the wheelchair lifting device after storage in the vehicle.

The wheelchair is stored in the rear luggage compartment or trunk of the vehicle after the user has transferred from the wheelchair to the vehicle. It is required that the user and the wheelchair move together by the vehicle and that the user can use the wheelchair again at the destination.
In this case, it is easy for the attendant to store the wheelchair in the vehicle after the user has moved from the wheelchair to the vehicle.
However, it is strongly desired from the independence of the wheelchair user that the used vehicle can store the wheelchair alone in the vehicle and that the stored wheelchair does not obstruct the running.

  As a wheelchair lifting device of the prior art, a gas spring is attached to an arm raised from the left and right ends of a base attached to a floor surface of a vehicle cabin or the like, and the two arms are connected by an arched arm. A swing lift in which a hook for hanging a wheelchair is attached to the center of the chair has been proposed (see, for example, Patent Document 1).

  As another wheelchair lifting device in the prior art, the support column is stored in a lying state in the trunk room of a passenger car, and is turned upright by an electric cylinder. The support column is bent into an L shape, and an electric take-up reel is attached to the tip of the support column. There has been proposed a wheelchair-mounted device in which an internal head is provided, and when a wheelchair is loaded, a wheelchair placed on a carriage is lifted by an electric take-up reel and pulled into a trunk room (for example, see Patent Document 2).

  As another wheelchair lifting device of the prior art, a support column is erected on a floor surface of a vehicle cabin or the like, and the base end of the support rod is pivotally supported by a support shaft provided on the support column. A simple lift device for a vehicle has been proposed in which a gas damper for limiting an ascending speed and a gas damper for balance are passed between the base end and the support column (see, for example, Patent Document 3).

JP-A-2005-104440 JP-A-11-78663 Registered Utility Model Publication No. 3048357

  In the swing / lift proposed by the cited document 1 and the like, there is a problem that a space for turning the arched arm has to be secured, and a space larger than the volume of the folded wheelchair is required. Further, there is a problem that the arch-shaped arm when not in use becomes an obstacle inside the automobile having a limited internal volume.

  In the wheelchair-mounted device proposed by the cited document 2 or the like, there is a problem that the displacement region of the column that rotates around the shaft pin that is horizontally disposed near the floor portion of the automobile is small. In addition, there is a problem that an operator must perform an auxiliary operation such as displacing the suspended wheelchair in order to prevent the wheelchair and the carriage holding it from interfering with the automobile and damaging the automobile. In addition, there is a head for winding up the belt at the tip of the column, and the movement range of the wheelchair and the carriage holding the head is limited by the head, or conversely, the displaceable range of the head is reduced. There is also a problem.

  In the simple lift device for a vehicle proposed by the cited reference 3 and the like, the swing speed of the saddle that hangs the wheelchair is limited by the gas damper for rising speed limitation and the gas damper for balance, and the lower limit of swing is defined by the intermediate bucket and Since it is performed by the latch lock, it is necessary for the operator to support the wheelchair by hand, and there is a problem that the wheelchair user may not be able to use it.
