Next, the usage method and effect | action of the assistance apparatus 1 of embodiment are demonstrated. Hereinafter, the case where the person M who is sitting in the chair C performs the standing up operation will be described as an example. If the assistance device 1 is far away, the assistant moves the assistance device 1 to the vicinity of the person being assisted M in advance. The person M who is in the sitting posture first pulls the assistance device 1. Then, as shown in FIG. 2, both legs of the person being assisted enter the lower side of the holding member 5. Here, when the holding member 5 becomes an obstacle, the person being assisted M lifts the lower end portion of the holding member 5 by hand, or moves the lower end portion of the holding member 5 or the second handle base shaft portion 541 of the second handle 54. Lift with your knees. Next, the person being assisted M places both feet on the ground mark 241. The lower leg of the person being assisted M contacts or approaches the lower leg pad 25.

Next, the person being assisted M starts an initial operation routine of the standing assistance program of the control unit 6. Thereby, the height of the elevating member 31 is automatically adjusted according to the physique of the person being assisted. Next, the person being assisted M places his upper body close to the body receiving portion 52 and puts both arms forward from above the side receiving portion 53. Furthermore, the person being assisted M holds the left and right first handle portions 432 of the first handle 43 with both hands. Thereby, it will be in the sitting position of the assistance person M shown by FIG. In the sitting position, the upper body of the person being assisted M is in a slightly forward tilted posture. The posture of the holding member 5 at this time is the posture at the time of sitting.

Subsequently, the person being assisted M starts the standing up assistance routine of the standing up assistance program. As a result, the vertical movement of the elevating member 31 and the forward swing of the swing arm member 41 are performed in a coordinated manner. At the time when the standing assistance program is completed, the elevating member 31 is raised, and the swing arm member 41 is swung forward to be in the standing position of the person being assisted M shown in FIG. In the standing state, the upper body of the person being assisted M is in a largely forward tilted posture. The posture of the holding member 5 at this time is the posture at the time of transfer. The first handle portion 432 is disposed on the front side of the holding member 5 in the transfer posture. The second handle portion 542 is disposed below the holding member 5 in the transfer posture, and is disposed behind the side position of the person being assisted M supported by the side receiving portion 53.

The seating movement of the person being assisted M is almost the reverse of the standing movement, so the explanation is omitted. Note that a part of a series of standing motions of the person being assisted M described above may be assisted by the assistant, or may be performed by the assistant.

The caregiver can move the caregiver M in the standing posture shown in FIG. 3 together with the care device 1 and transfer the caregiver M to a place other than the chair C. As can be seen by comparing FIG. 2 and FIG. 3, the support surface 521 of the trunk receiving portion 52 in the transfer posture is closer to the horizontal than the support surface 521 in the sitting posture. Therefore, the person being assisted M can leave the weight in the holding member 5 and move in an easy posture.

Here, attention is paid to the center of gravity position G of the total weight of the weight of the care recipient M held by the holding member 5 and the own weight of the assistance device 1. As shown in FIG. 3, the gravity center position G is directly below the second handle portion 542 in the front-rear direction. In other words, the position of the second handle portion 542 coincides with the gravity center position G in the front-rear direction. For this reason, when the assistant grips the second handle portion 542, it is easy to apply the movement operation force and the movement operation force is easily transmitted to the assistance device 1. Therefore, it is easy to move sideways and turn around. In addition, the position of the assistance device 1 can be easily controlled.

It should be noted that the position of the second handle portion 542 is more preferably coincident with the gravity center position G in the front-rear direction, but is not limited thereto. In other words, if the second handle portion 542 is at least partially disposed on the lower side in the front-rear direction range of the holding member 5 in the transfer posture, the second handle portion 542 is positioned in the vicinity of the gravity center position G in the front-rear direction. As a result, the mobility of the assistant is improved. Similarly, the second handle portion 542 is at least below the holding member 5 in the transfer posture and at least between the front end of the holding member 5 and the rear end of the foot of the person being assisted M in the front-rear direction. If a part is arranged, the second handle portion 542 is positioned in the vicinity of the gravity center position G in the front-rear direction, and the moving operability of the assistant is improved.

Next, the case where the assistance apparatus 1 is moved to the narrow toilet private room 91 and the person to be assisted M is transferred to the Western-style toilet 93 will be described. FIG. 6 is a plan view for explaining a situation in which the assistance device 1 is moved to the toilet room 91 and the person to be assisted M is transferred to the western-style toilet 93. In FIG. 6, the holding member 5 and the person being assisted M are not shown. As FIG. 6 shows, the entrance / exit 92 of the toilet private room 91 is provided in the side wall surface. Accordingly, the assistant moves the assistance device 1 at the position indicated by the broken line while reversing the direction, and performs lateral movement and super turning as necessary, so that the front position of the western-style toilet 93 indicated by the solid line It is necessary to move to.

Here, the concave portion 242 at the center of the rear part of the footrest 24 is formed in accordance with the outer shape of the lower part 94 of the western-style toilet 93. Therefore, the movement space is widened by the indentation dimension of the recess 242 into which the lower part 94 of the western-style toilet 93 can be engaged, and the assisting device 1 can be easily moved. Further, the presence of the recess 242 facilitates the centering of the assistance device 1 with respect to the western toilet 93. For example, first, the assisting device 1 can be retracted from an oblique direction so that the concave portion 242 contacts the lower portion 94 of the western toilet 93, and then the assisting device 1 can be turned around the concave portion 242.

In addition, the concave portion 242 gently acts on the sitting operation of the person being assisted. That is, since the person being assisted M can sufficiently approach the western-style toilet 93 by the size of the recess 242, there is no possibility of falling from the western-style toilet 93, and re-sitting due to shallow sitting is also reduced. Further, the standing person M can easily stand up.
