  In order to reduce the burden on caregivers when taking caregivers such as the elderly and disabled people who cannot walk by themselves into the bathtub, bathing chairs, means for reclining the whole bathing chair, and bathing chairs And moving the bathing chair in a substantially horizontal direction so that when the bathing chair is reclined, the entire bathing chair becomes higher than the height of the bathtub tub. There has been proposed a bathing apparatus (see Patent Document 1) that can be moved between the outside of the bathtub and the inside of the bathtub just beyond the tub of the bathtub.

  In other words, in the case of the above bathing device, after the care recipient is seated in the bath chair, the entire bath chair is placed in a reclining posture to enter the bathtub, and the height of the bath chair is greatly increased when entering the bath. There is no need to let them. Therefore, it can be used even in a bathroom with a low ceiling height.

However, since the bathing apparatus is configured so that the entire bathing chair is placed in a reclining posture and is bathed in the bathtub, when viewed from above, the bath chair has a longer longitudinal dimension when bathing, and a bath having a larger longitudinal dimension. Can only be used for Therefore, it is not suitable for small-scale care facilities or ordinary households with only a small bathtub.
Moreover, the reclining posture like the above bathing device becomes a posture in which the upper body is extremely sleeping compared with a general bathing posture, and there is a possibility that the care recipient may be uncomfortable.

  Moreover, in the case of the above bathing device, the cared person is transferred to the bathroom by a wheelchair, and the caregiver supports it as needed to transfer from the wheelchair to the bathing chair, but the bathroom floor is wet. If the caregiver is transferred, the caregiver may slide his / her foot and the caregiver or the caregiver may fall down and get injured.

On the other hand, as shown in FIGS. 18 and 19, a bathing care wheelchair (shower carry) provided with a chair body 200 and a carriage 300 that supports the chair body 200 from below so that the chair body 200 can be attached and detached and can be run in a mounted state. ) 100 has been proposed (see Patent Document 2).
That is, this bathing care wheelchair 100 is used as follows.
(1) A cared person M who is a user undressed in a bedroom or next room of a bathroom can receive a buttocks by a seat 210 and a back by a backrest 220. It sits so that F can be received by the footrest part 310 provided in the cart part 300 side.
(2) A caregiver (not shown) pushes the carriage unit 300 to move the bathing care wheelchair 100 to move to the bathroom with the care receiver M seated.
(3) The caregiver puts the suspension belt S, which is a suspended strip whose upper end is locked to the suspension part 400 of the lift device provided near the bathtub T in the bathroom, on the backrest part 220 and the seat part 210. It is made to latch on the latching | locking part provided in.
(4) The caregiver unlocks the locking means of the chair body 200 to the carriage 300 and has four upper ends (only two are shown in the figure) engaged with the suspension L1 of the lift device L. The lower end of the suspension belt S is engaged with engagement portions provided on the left and right sides of the seat portion 210 of the chair main body portion 200 and on the left and right sides of the backrest portion 220.
(5) The lift device L is operated to lift the chair main body 200 via the four suspension belts S, and the chair main body 200 is separated from the carriage 300 as shown in FIG.
(6) As shown by a two-dot chain line in FIG. 18, while lifting the lower limb of the cared person M from below so that the foot F of the cared person M does not get caught in the heel T <b> 1 of the bathtub T, the chair main body 200. Is moved to a bathing position facing the inside of the bathtub T (hereinafter referred to as “method 1”), or as shown in FIG. 19, the chair main body 200 is lifted to a sufficient height so as not to be caught by the tub T1 of the bathtub T. After that, the chair body 200 is moved until it faces the inside of the bathtub T (hereinafter referred to as “method 2”).
(7) The caregiver operates the lift device to suspend the chair main body 200, and together with the chair main body 200, the care recipient M enters the bathtub T to perform bathing care.
(8) After the completion of bathing, the procedure of the above operations (7) and (6) is carried out in the reverse direction, and the chair body 200 is attached to the carriage 300.

Japanese Patent Laid-Open No. 2001-79060 JP 2008-253426 A

  However, in the case of the method 1, the above-mentioned bathing care wheelchair 100 is the chair main body 200 while lifting the lower limb side of the care receiver M from below so that the foot F of the care receiver M is not caught on the heel of the bathtub T. However, the chair main body 200 must be moved to the tank position facing the inside of the bathtub T. Therefore, when only one caregiver enters the tank, the caregiver has to operate the lift device while bending over, tilting the body, or taking an unnatural posture. In addition to being bad, there is a risk of overloading the caregiver's body.

On the other hand, in the case of Method 2, although the burden on the caregiver is reduced, it is necessary to lift the chair main body portion high, and there is a fear of giving fear to the care recipient M. In addition, method 2 cannot be adopted in small-scale nursing care facilities and general households where the ceiling height is generally low, because the chair body 200 cannot be lifted by a lift device.
In addition, in the case of the above bathing care chair 100, the foot F is not supported, and the care receiver M is allowed to enter in a state of hanging down from the seat portion 210, so the chair body portion 200 is lowered. First, the foot F hits the bottom of the bathtub T, and the cared person M sitting on the chair body 200 may lose balance in the bathtub T.

  In view of the above circumstances, the present invention eliminates the need to enlarge the bathtub, and even if the lifting height of the chair main body is lowered, the seated person's foot does not get caught in the bathtub heel. An object of the present invention is to provide a care chair that allows a person to enter a bathtub easily and safely using a lift device.

In order to achieve the above object, a nursing chair according to the first aspect of the present invention includes a chair main body portion and a foot support portion, and the chair main body portion has a seat portion and a backrest portion. The foot support portion includes a footrest portion for receiving a foot, a frame-like footrest support portion in which the footrest portion is supported at one end and the other end is supported by the chair body portion, The foot support portion is lifted by the care chair, the seat portion having a seat plate and a seat plate support frame for supporting the seat plate from below, and the other end of the footrest support portion is the foot The mounting portion side is pivotable in the vertical direction, is pivotally supported by the end portion of the seat plate support frame on the backrest portion side from the front end of the seat plate, and the locking portion of the strip is, It is provided in the foot support part.

Although the nursing chair of the present invention is not particularly limited, it is configured to include only a chair main body portion and a foot support portion, or a chair main body portion, and the chair main body portion is supported from below so that the chair main body portion can be attached and detached and can be run in a mounted state. It can be set as the structure which has a trolley | bogie part.
In the case of the former configuration, if the nursing chair is placed so that the nursing chair of the present invention can be received by the seat and the backrest of the wheelchair used in the room, the nursing chair can be used by the wheelchair. In the state where a user such as a cared person is seated on the chair, the patient is transported to the bathroom, lifted so that the care chair is separated from the wheelchair using the lifting strip of the lift device, and the user is placed on the care chair. It is possible to enter the tank in a wet state.
In addition, when a wheelchair used in a living room is used instead of a carriage as described above, a lock means is provided on the chair body or the wheelchair so that the chair body can be locked to the armrest of the wheelchair while being placed on the wheelchair. It is preferable to do so.

The lower strip suspended body above SL, provided so as to be interposed between the lifting device and the chair body portion, if it is possible to raise and lower the chair body portion by lifting by the lift device is not particularly limited, for example, hanging belt , Wire ropes, chains, and combinations of these with hooks.
The shape of the strip locking portion is not particularly limited as long as the suspended strip can be locked and does not hinder the lifting, and examples thereof include a ring shape, a hook shape, and a groove shape.

The care chair of the present invention is not particularly limited as a mechanism that can move the footrest portion upward, and examples thereof include the following (1) to (4).
(1) A mechanism for rotatably supporting one end of the footrest support portion of the foot support portion on the chair main body portion via a foot support pivot shaft parallel to the width direction of the chair main body portion.
(2) In the mechanism of the above (1), one end of the chair body is rotatably supported on the lower surface of the seat portion via an axis parallel to the foot support pivot shaft, and the other end is supported on the foot support pivot shaft. A support arm that is pivotally supported is provided, and as the footrest moves upward, the support arm rotates, and the foot support pivot pivot moves backward (in the direction of the backrest). The mechanism that the footrest part moves also to the rear of the seat part.
(3) A mechanism in which the chair body portion has a guide portion that is inclined so as to approach the backrest portion toward the upper side, and the footrest support portion is supported so as to slide along the guide portion.
(4) A force for fixing the footrest support portion to the seat portion, supporting the seat portion to the backrest portion so as to be rotatable through a seat portion pivot shaft parallel to the width direction, and lifting the footrest support portion Is a mechanism in which the foot support part is also rotated together with the seat part to move the footrest part upward by rotating the seat part around the seat part pivot shaft.
In the mechanism (4), the seat has a circular arc shape that is downwardly convex as viewed in a cross section cut along the central axis in the width direction, and the seat pivot is centrally located at the center of the arc. It is preferable to have a configuration that matches.

  The care chair of the present invention is not particularly limited, and may include, for example, a headrest that supports the head of a seated user, an armrest that supports the arm, and a legrest that supports the calf.

Since the care chair of the present invention is configured as described above, it is not necessary to enlarge the bathtub, and even if the lifting height of the chair main body portion is lowered, the seated caregiver's foot is still in the bathtub. The cared person can enter the bathtub easily and safely using the lift device without being caught by the bag.

  In other words, in a bedroom or next room of the bathroom, after the person to be cared is seated on the chair body, the chair body is mounted on the carriage or on the wheelchair used in the living room. After transporting to the vicinity of the lift device, at least one suspension strip of the lift device is locked at a predetermined position of the chair body (for example, a locking portion provided on a frame constituting the outer edge of the backrest). In addition, at least one other suspension strip of the lift device is locked at a predetermined position of the foot support part (for example, a locking part provided on the foot support part), and the posture of the chair body part is in the seating state. If the chair body and the foot support are lifted by a plurality of suspension strips while maintaining a balance so that it can be safely maintained, the cared person can maintain a sitting posture. , Lifted along with the chair body portion and a foot support unit.

At this time, since the footrest is movable at least upward, the position of the footrest can be increased by lifting. That is, the caregiver is lifted upward without supporting the caregiver's ankle or calf.
Therefore, even if the chair main body is not greatly lifted, the footrest is not caught by the tub of the bathtub, and the chair main body and the footrest can be arranged directly above the bathtub. In addition, the caregiver does not operate the lift device while taking an unreasonable posture.

  Furthermore, since the movement of the footrest part can be performed without interlocking with the movement of the backrest part, only the footrest part can be moved upward without tilting the backrest part in the horizontal direction. . That is, since it can be made to enter in a state where the size of the chair body in the front-rear direction (the direction from the backrest side to the footrest side) is short in plan view, there is only a bathtub with a short longitudinal dimension. It is possible to enter the tank without lifting it high.
