Description

  The present invention relates to a transfer apparatus and a wheelchair for transfer movement, and more particularly, to a transfer apparatus and a transfer movement wheelchair including a movable chassis and a lifting / transferring support mechanism fixed to the chassis.

  In recent years, in a society where it is indispensable for the care recipient to require home care, transfer is a heavy labor for a powerless caregiver, and it is difficult to transfer if the power is insufficient. For example, when a care recipient is transferred from a bed to a wheelchair, the care recipient is lifted by the caregiver's hand and transferred to the wheelchair. Such care places a burden on the back of the caregiver, causing back pain and increasing the burden on the caregiver.

In view of such a situation, Patent Literature 1 proposes an assisting device that includes a frame to which a breastplate is attached, a shaft that holds the frame, and a pedal that is attached to the frame.
According to the assisting device of Patent Document 1, the human body is lifted up to an arbitrary place by leaning on the breast pad, stepping on the pedal, rotating the frame around the axis, and tilting the breast pad forward. Can be moved. Thereby, since the care recipient can be lifted by using the force of the foot that can apply a force greater than that of the hand, the burden on the caregiver can be reduced.

JP 2000-296154 A

  However, in the assistance device of Patent Document 1, when a caregiver depresses a pedal, the depressing force is directly transmitted to the chest of the care recipient who is leaning against the breastplate through the frame. For this reason, for example, when the caregiver puts the entire weight and steps on the pedal, an abrupt force is transmitted to the chest of the care recipient and sometimes places a burden on the care recipient. On the other hand, in order to step on the pedal so that a sudden force is not transmitted to the care recipient's chest, the caregiver needs to step on the pedal slowly, which may cause a burden on the caregiver's foot.

  An object of this invention is to provide the transfer apparatus which can reduce the burden on a care recipient's body at the time of transfer while being able to reduce the burden of a caregiver.

(1) There is a transfer device comprising a movable chassis and a lifting / transferring support mechanism fixed to the chassis,

The rear side restriction side abuts on the front side surface of the rear lifting support frame and restricts the rotation of the rear lifting support frame toward the front side.

With such a configuration, when the care recipient places the upper body on the body placing portion, the rear side surface of the front lifting support frame comes into contact with the front restriction side of the lifting support frame stopper, and the body placing portion is stabilized. In addition, when the care recipient is lifted on the body rest portion, the front side surface of the rear lifting support frame comes into contact with the rear side regulation edge of the lifting support frame stopper when the body rest portion is lifted up to a predetermined position. The part can be prevented from falling before a predetermined position.
As a result, the care recipient can rest his / her upper body on the body resting portion with peace of mind, and can reduce anxiety when lifted.
