The sheet-like body 40 has the strength to suspend the care recipient P, and has the flexibility to be wound and rewound by the first winding mechanism 50 and the second winding mechanism 55. It is a member to have, and the material is not particularly limited. For example, the sheet-like body 40 can be formed of a cloth, and in this case, it is preferable to use a well-ventilated mesh-like cloth in order to prevent the care recipient P from getting stuffy. It is also possible to form the sheet-like body 40 in a bamboo blind shape, and in this case, it is possible to effectively prevent the shape from being lost. The sheet-like body 40 of the present embodiment has a length that supports the whole body of the care recipient P, but it is not always necessary to support the whole body of the care recipient P, for example, the knee of the care recipient P. It may be a length that protrudes from the tip.

As shown in FIGS. 1 and 3, the first winding mechanism 50 includes a first winding shaft 51 and a first winding shaft in which one side of the sheet-like body 40 in the width direction is connected so as to be able to wind and rewind. The 51 has a first rotation drive member 52 such as an electric motor capable of rotating forward and reverse. The first take-up shaft 51 is rotatably supported between the first front elevating arm 20F and the first rear elevating arm 20R, and is used for the elevating operation of the first front elevating arm 20F by the first elevating mechanism 30. 1 It also functions as a connecting member to follow the rear lifting arm 20R.

The first elevating mechanism 30 can be configured to elevate the first rear elevating arm 20R, and the first rotation drive member 52 may be provided on the first rear elevating arm 20R.

Similarly, the second take-up mechanism 55 can rotate the second take-up shaft 56 and the second take-up shaft 56, in which the other side of the sheet-like body 40 in the width direction is connected so as to be able to take up and rewind, in the forward and reverse directions. It has a second rotation drive member 57 such as an electric motor. The second take-up shaft 56 is rotatably supported between the second front elevating arm 25F and the second rear elevating arm 25R, and is used for the elevating operation of the second front elevating arm 25F by the second elevating mechanism 35. 2 It also functions as a connecting member for following the rear lifting arm 25R. The second rotation drive member 57 is supported by the second front elevating arm 25F. The second elevating mechanism 35 may be configured to elevate the second rear elevating arm 25R, and the second rotation drive member 57 may be provided on the second rear elevating arm 25R.

The posture change device 1 further includes a control device (not shown) that controls the operation of the first elevating mechanism 30 and the second elevating mechanism 35, and the operation of the first winding mechanism 50 and the second winding mechanism 55 (not shown). The posture of the care recipient can be changed manually or automatically by inputting from the operation panel (not shown).

Next, the operation of the above-mentioned posture changing device 1 will be described. In response to the main power ON operation of the posture changing device 1 or the reset operation during the operation of the posture changing device 1, the control device is in the initial state (normal state) of the posture changing device 1 as shown in FIGS. 1 to 3. As described above, the first elevating mechanism 30 and the second elevating mechanism 35, and the first winding mechanism 50 and the second winding mechanism 55 are operated. In the initial state, the positions of the first elevating body 20 (first front elevating arm 20F, first rear elevating arm 20R) and the second elevating body 25 (second front elevating arm 25F, second rear elevating arm 25R) are set. In the descending position, the care recipient P is placed on the sheet-like body 40.

As shown in FIGS. 1 and 3, in the initial state, the first take-up shaft 51 and the second take-up shaft 52 are preferably arranged above the recumbent position space S, and the first take-up shaft 51 and the second take-up shaft 51 and The second take-up shaft 52 can also function as a handrail. When the bed 100 has a back-raising function such as a reclining bed, it is preferable that the sheet-like body 40 is sufficiently loosened in an initial state so as not to impede this function.

When the position of the care recipient P is changed, the care recipient P receives a manual input from the operation panel or an automatic input by a timer or the like, and the care recipient P is moved upward from the lying space S by the sheet-like body 40. The first elevating mechanism 30 and the second elevating mechanism 35 are raised, and the first winding mechanism 50 and the second winding mechanism 55 are wound so as to be lifted to. This state is shown in FIGS. 5 to 7.

Then, when one of the first winding mechanism 50 and the second winding mechanism 55 is wound and the other is rewound, the control device causes the care recipient as shown in FIGS. 8 to 10. The posture of P changes from the supine position to the side where the sheet-like body 40 is rewound.

As described above, the body position changing device 1 according to the present embodiment winds one of the first winding mechanism 50 and the second winding mechanism 55 in a state where the care recipient P is lifted upward from the lying position space S. The position of the care recipient P can be changed by moving the sheet-like body 40 by performing a picking operation and a rewinding operation of the other. Therefore, it is possible to easily and surely change the position of the care recipient, and it is possible to reduce the work load of the caregiver. The position change of the care recipient can be performed in either the left or right direction by selecting either the first winding mechanism 50 or the second winding mechanism 55 that performs the rewinding operation, and the winding amount and the winding amount can be changed. By increasing the amount of rewinding, the body position can be changed to the prone position.

The repositioning of the care recipient P can be suitably used not only for the purpose of preventing bedsores but also for the purpose of assisting the care recipient P in changing clothes, and is further placed in the lying position space S. It can also be used to replace mats and mattresses.

Further, when the mattress is inserted between the care recipient P in the supine position and the sheet-like body 40, the mattress is rotated together with the care recipient P in a prone position and moved above the back. By removing the mattress in use, placing a new mattress on the back, and rotating it to the supine position again, the mattress can be replaced quickly and easily.

After the position of the care recipient P is changed, the control device can return to the initial state by lowering the first elevating mechanism 30 and the second elevating mechanism 35. When the position of the care recipient P is likely to return to the original state due to "habit" related to the position of the care recipient P, one-sided elevation that raises only one of the first elevating body 20 and the second elevating body 25 By setting the state, the position of the care recipient P can be maintained in a desired state. For example, FIGS. 11 to 13 show a one-sided ascending state in which only the first elevating body 20 is raised.

The control device can store an automatic position change program, and according to this automatic position change program, the first elevating mechanism 30 and the second elevating mechanism 35, as well as the first elevating mechanism 30 and the second elevating mechanism 35 every predetermined time elapse (for example, every two hours). , The operation control of the first take-up mechanism 50 and the second take-up mechanism 55 can be automatically performed. As a result, the caregiver does not have to wake up at night to perform the posture change work, so that the work load can be significantly reduced.
