TECHNICAL FIELD The present invention relates to an elderly person with weak legs,
The present invention relates to a human body transfer device applied to transfer of a physically handicapped person or the like from a wheelchair to a bed or to a wheelchair and a toilet seat, a shower chair, a sofa, a car seat, or the like.

[Prior art]

[0002] Conventionally, in this type of transfer device, a structure in which a person to be transferred is hoisted by a belt or the like takes time and effort when hoisting the person to be transferred or lowering the object to be transferred.
Instability due to the lifting operation also poses a problem, so with the intention of solving this problem, for example, one in which a column is stood upright on a turntable and a support plate is provided at its tip (special (See Kaihei No. 1-195857), and a pillar is erected on a pedestal with casters, and a tiltable branch pillar is taken out from a position substantially corresponding to the height of the knee of the pillar.
A device in which a body holder is provided at the tip of the branch post (Japanese Patent Laid-Open No. 3-2980)
No. 218755) is proposed.

However, since both the former and the latter have a structure in which the pillar and the branch pillar are erected by stepping on the pedal, the main pillar and the branch pillar in a state in which the upper half of the person to be transferred is placed on the receiving plate and the holder. It is not easy to stand up and incline slowly and quietly.Therefore, you may step on the pedal too hard and abruptly erect and incline the main pole and branch pole, resulting in unstable posture and A sudden change in the line-of-sight angle may cause a sense of dread. Furthermore, this point is that when lowering the transferred person from the device to the target transferred object, it must be operated in consideration of the momentum of the descending of the weight center of gravity of the transferred person, and the transferred person should be facing backwards. Considering this, the anxiety may be further amplified, leading to refusal to use the device.

In particular, when the caregiver is a weak woman or the elderly is difficult to operate, and when the upper half of the person to be transferred is placed on the receiving plate or holding tool, the inclination angle,
There is also a problem that the height and position cannot be changed, which is inconvenient.

Therefore, in order to solve the above-mentioned problems, a supporting column is erected on a pedestal having casters, and a horizontal frame, on which the supporting plate of the person to be transferred is tiltably supported at its tip, is vertically moved. It is mounted so that it can be moved up and down by means of a tilting angle adjusting mechanism for the receiving plate on the horizontal frame, and the receiving plate is formed into a substantially circular shape in plan view so that it can be opened and closed in the radial direction and a plurality of auxiliary members. A plate is pivotally formed to form the chest of the human body on the receiving plate.
