The first support portion 21 is fixed to a substantially central portion on the upper surface of the carriage portion 10 with the longitudinal direction thereof being directed in the vertical direction.

第二支持部22は、略直方体状の部材である。第二支持部22は、その長手方向を上下方向に向けた状態で配置される。第二支持部22は、第一支持部21に対して上下方向に摺動可能となるように、当該第一支持部21の中心部(平面視における中央部)に挿通される。第二支持部22は、その上端が第一支持部21の上方に突出し、その下端が当該第一支持部21の内部に位置するように配置される。   The second support part 22 is a substantially rectangular parallelepiped member. The 2nd support part 22 is arrange | positioned in the state which orient | assigned the longitudinal direction to the up-down direction. The second support portion 22 is inserted into the center portion (center portion in plan view) of the first support portion 21 so as to be slidable in the vertical direction with respect to the first support portion 21. The second support part 22 is arranged such that its upper end protrudes above the first support part 21 and its lower end is located inside the first support part 21.

傾斜アクチュエータ23は、第二支持部22を第一支持部21に対して摺動させるための駆動源である。傾斜アクチュエータ23は、回転力を発生させることが可能なモータにより構成される。傾斜アクチュエータ23は、第一支持部21の前面に固定される。傾斜アクチュエータ23の駆動力(回転力)は、ベルト23a及び第一支持部21内に配置された動力伝達機構を介して第二支持部22へと伝達される。この際、前記動力伝達機構によって、傾斜アクチュエータ23の回転方向の駆動力は、直線方向(上下方向)への駆動力へと変換される。これによって、傾斜アクチュエータ23を駆動させると、第二支持部22を第一支持部21に対して上下方向に摺動させることができる。   The tilt actuator 23 is a drive source for sliding the second support portion 22 with respect to the first support portion 21. The tilt actuator 23 is constituted by a motor capable of generating a rotational force. The tilt actuator 23 is fixed to the front surface of the first support portion 21. The driving force (rotational force) of the tilt actuator 23 is transmitted to the second support portion 22 via the belt 23a and a power transmission mechanism disposed in the first support portion 21. At this time, the driving force in the rotational direction of the tilt actuator 23 is converted into a driving force in the linear direction (vertical direction) by the power transmission mechanism. Accordingly, when the tilt actuator 23 is driven, the second support portion 22 can be slid in the vertical direction with respect to the first support portion 21.

連結ロッド24は、第一支持部21と上半身保持部30とを連結するものである。連結ロッド24の一端は、第一支持部21の左右側面の上端部近傍に、左右方向の回動軸線を中心として回動可能に連結される。   The connecting rod 24 connects the first support part 21 and the upper body holding part 30.

次に、図9から図15までを用いて、上述の如く構成された移乗支援装置を用いて被介護者(被介護者P)を移乗する際の様子について説明する。ここでは一例として、被介護者PをベッドBから他の場所へと移乗する場合を想定して説明を行う。なお、説明の便宜上、移乗支援装置を操作する介助者の図示は省略している。   Next, using FIG. 9 to FIG. 15, a state when a care receiver (care receiver P) is transferred using the transfer support device configured as described above will be described. Here, as an example, a description will be given assuming that the care recipient P is transferred from the bed B to another place. For convenience of explanation, illustration of an assistant who operates the transfer support apparatus is omitted.

まず介助者は、図9(a)に示すように、座面部2をベッドBの上に置き、その上に被介護者Pを着座させる。またこの際、昇降部材90が受け部材50の連結部52よりも下方に位置するように、移乗支援装置の昇降アクチュエータ80は伸ばされている(図6参照)。   First, as shown in FIG. 9A, the caregiver places the seat surface portion 2 on the bed B and seats the cared person P thereon. At this time, the elevating actuator 80 of the transfer assisting device is extended so that the elevating member 90 is positioned below the connecting portion 52 of the receiving member 50 (see FIG. 6).

次に介助者は、図9(b)に示すように、移乗支援装置(本体部1)を移動させ、座面部2を連結機構3を介して本体部1に連結させる。この際介助者は、被介護者Pの足を足先保持部110(足受け部112)に載置すると共に、被介護者Pの膝を膝保持部100(膝受け部103)で前方から支持する。これによって、当該被介護者Pの膝及び足が、膝保持部100及び足先保持部110によって保持される。以下では、この際の座面部2を本体部1に連結させる様子について詳細に説明する。   Next, as shown in FIG. 9B, the assistant moves the transfer support device (main body part 1) and connects the seat surface part 2 to the main body part 1 via the connection mechanism 3. At this time, the caregiver places the cared person's P foot on the toe holding part 110 (foot receiving part 112) and the knee of the cared person P from the front by the knee holding part 100 (the knee receiving part 103). To support. Accordingly, the knee and the foot of the care receiver P are held by the knee holding unit 100 and the toe holding unit 110. Below, a mode that the seat surface part 2 in this case is connected with the main-body part 1 is demonstrated in detail.

図11に示すように、介助者は移乗支援装置の本体部1を移動させることで、連結部52の受け部52a内に座面部2の連結部43を挿入する。この際、連結部52の受け部52aの高さが座面部2の連結部43の高さと一致しない場合には、介助者は当該連結部52を持って上下に摺動させることで、高さを合わせることができる。また、受け部52aの後端部は上下方向幅が広くなっているため、当該受け部52aと座面部2の連結部43の高さが多少異なっていても、当該連結部43を受け部52aへと容易に案内することができる。   As shown in FIG. 11, the assistant moves the main body 1 of the transfer assist device to insert the connecting portion 43 of the seat surface portion 2 into the receiving portion 52 a of the connecting portion 52. At this time, if the height of the receiving portion 52a of the connecting portion 52 does not coincide with the height of the connecting portion 43 of the seating surface portion 2, the assistant can hold the connecting portion 52 and slide it up and down. Can be combined. In addition, since the rear end portion of the receiving portion 52a is wide in the vertical direction, even if the height of the connecting portion 43 of the receiving portion 52a and the seat surface portion 2 is slightly different, the receiving portion 52a. Can be easily guided to.

受け部52a内に座面部2の連結部43が挿入されると、当該連結部43と保持部材70の後端面とが当接する。しかし、当該保持部材70の後端面は傾斜するような形状に形成されているため、当該保持部材70は連結部43に押されて上方へと回動する。これによって保持部材70が上方へと逃がされるため、連結部43は受け部52a内を前方へと進入することができる。   When the connecting portion 43 of the seat surface portion 2 is inserted into the receiving portion 52a, the connecting portion 43 and the rear end surface of the holding member 70 come into contact with each other. However, since the rear end surface of the holding member 70 is formed in an inclined shape, the holding member 70 is pushed by the connecting portion 43 and rotates upward. As a result, the holding member 70 is released upward, so that the connecting portion 43 can enter the receiving portion 52a forward.

図12に示すように、介助者が本体部1をさらに後方へと移動させることで、受け部52aの奥(前端部近傍)まで座面部2の連結部43が挿入される。これによって、当該連結部43が、下方に向けて突出された保持部材70の後端部よりも前方に位置することになると、当該保持部材70が再び下方へと回動する。この際、図13に示すように、下方へと回動した保持部材70の後端部が、座面部2の連結部43に形成された切欠部43aに係合する。このように、保持部材70が座面部2の連結部43と係合することによって、当該連結部43が受け部52aに保持される(受け部52aからの脱落が防止される)ことになる。すなわち、この状態においては、介助者が手動で保持部材70を上方に回動させ、連結部43との係合を解除しない限り、座面部2を連結部52から取り外すことはできない。   As shown in FIG. 12, the assistant moves the main body 1 further to the rear, whereby the connecting portion 43 of the seat surface portion 2 is inserted to the back of the receiving portion 52a (near the front end). As a result, when the connecting portion 43 is positioned in front of the rear end portion of the holding member 70 protruding downward, the holding member 70 is rotated downward again. At this time, as shown in FIG. 13, the rear end portion of the holding member 70 rotated downward is engaged with a notch 43 a formed in the connecting portion 43 of the seat surface portion 2. Thus, when the holding member 70 engages with the connecting portion 43 of the seat surface portion 2, the connecting portion 43 is held by the receiving portion 52a (a drop-off from the receiving portion 52a is prevented). That is, in this state, the seat surface portion 2 cannot be removed from the connecting portion 52 unless the assistant manually rotates the holding member 70 upward to release the engagement with the connecting portion 43.

また、図13(a)に示すように、座面部2の連結部43が受け部52aの奥まで挿入された状態においては、当該座面部2のアーム42が支持部材60の内部に挿入され、当該支持部材60によって支持されている。このように、アーム42を支持部材60によって支持することで、被介護者Pが着座した座面部2を強固に支持することができる。   Further, as shown in FIG. 13A, in a state where the connecting portion 43 of the seat surface portion 2 is inserted to the back of the receiving portion 52a, the arm 42 of the seat surface portion 2 is inserted into the support member 60, It is supported by the support member 60. Thus, by supporting the arm 42 by the support member 60, the seat surface portion 2 on which the care receiver P is seated can be firmly supported.

次に介助者は、図14に示すように、昇降アクチュエータ80を縮めて昇降部材90を上方へと移動(上昇)させる。昇降部材90の後端部(上方に向けて突出した部分)は、連結部52の切欠部52bを介して当該連結部52内へと進入し、当該昇降部材90の上端面91が座面部2の連結部43に下方から当接する。昇降部材90の上端面91は、後上方から前下方に向かって傾斜するように形成されているため、当該上端面91(傾斜面)によって、座面部2の連結部43はさらに前方(受け部52aの奥)へと押される。これによって、連結部43がより強固に受け部52aに保持されることになる。このように、座面部2の連結部43が受け部52aに受けられると共に、当該連結部43を保持部材70及び昇降部材90によって保持することで、座面部2を連結機構3を介して本体部1に連結することができる。特に本実施形態においては、上端面91が連結部43の外周に沿うような形状(円弧状に近い形状)に形成されているため、連結部43のガタつきを抑制することもできる。   Next, as shown in FIG. 14, the assistant contracts the lifting actuator 80 and moves (lifts) the lifting member 90 upward. The rear end portion (the portion protruding upward) of the elevating member 90 enters the connecting portion 52 through the notch portion 52b of the connecting portion 52, and the upper end surface 91 of the elevating member 90 is the seat surface portion 2. It contacts the connecting part 43 from below. Since the upper end surface 91 of the elevating member 90 is formed to incline from the rear upper side toward the front lower side, the connecting portion 43 of the seat surface portion 2 is further forward (receiving portion) by the upper end surface 91 (inclined surface). To the back of 52a). As a result, the connecting portion 43 is more firmly held by the receiving portion 52a. As described above, the connecting portion 43 of the seat surface portion 2 is received by the receiving portion 52a, and the holding portion 70 is held by the holding member 70 and the lifting member 90, whereby the seat surface portion 2 is connected to the main body portion via the connecting mechanism 3. 1 can be connected. In particular, in the present embodiment, since the upper end surface 91 is formed in a shape (a shape close to an arc shape) along the outer periphery of the connecting portion 43, rattling of the connecting portion 43 can be suppressed.

介助者がさらに昇降アクチュエータ80を縮めて昇降部材90を上昇させると、図15に示すように、当該昇降部材90によって連結部43が下方から押し上げられ、座面部2及び連結機構3が一体的に上昇する。またこの際、図15においては図示を省略しているが、連結機構3の連結部52の上面に当接している上半身保持部30の昇降部材32(図3参照)も、連結機構3に押し上げられて当該連結機構3と共に上昇する。このようにして、座面部2及び上半身保持部材33を一体的に上昇させることができる(図4参照)。すなわち、座面部2に着座した被介護者Pを、上半身保持部材33で保持しながらベッドBから持ち上げることができる。   When the assistant further contracts the lifting actuator 80 to raise the lifting member 90, the connecting portion 43 is pushed up from below by the lifting member 90 as shown in FIG. To rise. At this time, although not shown in FIG. 15, the lifting member 32 (see FIG. 3) of the upper body holding part 30 that is in contact with the upper surface of the connection part 52 of the connection mechanism 3 is also pushed up to the connection mechanism 3. And rises together with the connecting mechanism 3. In this way, the seat surface portion 2 and the upper body holding member 33 can be raised integrally (see FIG. 4). That is, the cared person P seated on the seat surface portion 2 can be lifted from the bed B while being held by the upper body holding member 33.

この際、座面部2に着座した被介護者Pの膝及び足を膝保持部100及び足先保持部110によって保持しながら、当該被介護者Pを持ち上げることができる。このように、被介護者Pの脚部(膝、並びに足首より先の部分)を保持することで、当該被介護者Pの姿勢を安定させることができる。また、被介護者Pの脚部を保持することで、座面部2と共に持ち上げられた際の被介護者Pの不安感を緩和させることができる。   At this time, the cared person P can be lifted while holding the knees and legs of the cared person P sitting on the seat surface part 2 by the knee holding part 100 and the toe holding part 110. Thus, the posture of the cared person P can be stabilized by holding the legs of the cared person P (the knee and the part ahead of the ankle). Further, by holding the legs of the cared person P, the anxiety of the cared person P when lifted together with the seat surface part 2 can be reduced.

またこの際、座面部2の高さを調節して、被介護者Pの目線と介助者の目線を同程度の高さとすることで、当該介助者は被介護者Pに威圧感を与えることなく、当該被介護者Pとの意思疎通を図ることができる。   At this time, by adjusting the height of the seat surface portion 2 so that the care recipient P and the caregiver's eyes are at the same height, the caregiver gives the caregiver P an intimidating feeling. In addition, communication with the care recipient P can be achieved.

上述の如く、座面部2を本体部1に連結させて、当該座面部2をベッドBから持ち上げた後(図9(b)参照)、介助者は、図10(a)に示すように、移乗支援装置(本体部1)を移動させることで、他の任意の場所まで運ぶことができる。この際にも、座面部2の連結部43は、保持部材70及び昇降部材90によって受け部52aに保持されたままであるため(図15参照)、座面部2が脱落するおそれがない。   As described above, after the seat surface portion 2 is connected to the main body portion 1 and the seat surface portion 2 is lifted from the bed B (see FIG. 9 (b)), the assistant, as shown in FIG. 10 (a), By moving the transfer support device (main body unit 1), it can be carried to any other place. Also at this time, since the connecting portion 43 of the seat surface portion 2 remains held by the receiving portion 52a by the holding member 70 and the elevating member 90 (see FIG. 15), there is no possibility that the seat surface portion 2 falls off.

また、再び座面部2を本体部1から取り外す場合、例えば被介護者Pを他のベッドBに着座させる場合には、介助者は、図16に示すように、昇降アクチュエータ80を伸長させて昇降部材90を下降させ、座面部2を他のベッドB上に載置する。介助者は、さらに昇降部材90を下降させることで、昇降部材90を座面部2の連結部43から離間させ、当該昇降部材90による連結部43の保持を解除することができる。   Further, when the seat surface portion 2 is removed from the main body portion 1 again, for example, when the care recipient P is seated on another bed B, the caregiver extends and lowers the lift actuator 80 as shown in FIG. The member 90 is lowered and the seat surface portion 2 is placed on the other bed B. The assistant can further lower the elevating member 90 to separate the elevating member 90 from the connecting portion 43 of the seat surface portion 2 and release the holding of the connecting portion 43 by the elevating member 90.

ここで、座面部2及び連結機構3は、昇降部材90に固定されているわけではなく、当該昇降部材90の上端面91によって下方から持ち上げられて支持されているだけである。このため、もし座面部2とベッドBとの間に障害物(例えば、物や人の手等)が挟まれていたとしても、昇降アクチュエータ80が伸長する駆動力が当該座面部2に伝達されることがないため、当該障害物に過度の負荷が加わるのを防止することができ、当該障害物を損傷させるおそれがない。   Here, the seat surface portion 2 and the coupling mechanism 3 are not fixed to the elevating member 90 but are only supported by being lifted from below by the upper end surface 91 of the elevating member 90. For this reason, even if an obstacle (for example, an object or a person's hand) is sandwiched between the seat surface portion 2 and the bed B, the driving force by which the elevating actuator 80 extends is transmitted to the seat surface portion 2. Therefore, it is possible to prevent an excessive load from being applied to the obstacle, and there is no possibility of damaging the obstacle.

さらにこの状態で、介助者が手動で保持部材70を上方に回動させ、連結部43との係合を解除することにより、当該連結部43を受け部52aから抜き取ることが可能となる。この状態で、介助者は本体部1を移動させて、座面部2を連結機構3から取り外すことができる。   Further, in this state, the assistant manually rotates the holding member 70 upward to release the engagement with the connecting portion 43, whereby the connecting portion 43 can be extracted from the receiving portion 52a. In this state, the assistant can move the main body 1 and remove the seat surface 2 from the coupling mechanism 3.

なお、上述の例の如く、座面部2を置くことができるベッドB(図16参照)等が無い場合には、昇降部材90を下降させ、連結機構3のスライド部51をストッパ31dに当接させることで当該スライド部51の下降が規制され、昇降部材90を座面部2の連結部43から離間させることができる。これによって、被介護者Pが座面部2に着座していない場合には、当該座面部2を任意の場所で取り外すことができる。   As in the above example, when there is no bed B (see FIG. 16) or the like on which the seat surface portion 2 can be placed, the elevating member 90 is lowered and the slide portion 51 of the coupling mechanism 3 is brought into contact with the stopper 31d. By doing so, the descent of the slide part 51 is restricted, and the elevating member 90 can be separated from the connecting part 43 of the seat surface part 2. Thereby, when the cared person P is not seated on the seat surface portion 2, the seat surface portion 2 can be removed at an arbitrary place.

次に、図5及び図10を用いて、移乗支援装置を用いて被介護者Pが下半身に身につけている衣服を着脱させる際の様子について説明する。   Next, using FIG.5 and FIG.10, the mode at the time of attaching and detaching the clothes which the care receiver P is wearing to the lower body using a transfer assistance apparatus is demonstrated.

まず介助者は、図5に示すように、被介護者P(図5においては図示を省略)を座面部2に着座させたまま、傾斜アクチュエータ23を駆動させ、第二支持部22を第一支持部21に対して上方に摺動(上昇)させる。これに伴って、第二支持部22に連結された保持部本体31も上昇しようとするが、連結ロッド24によってその上昇が拘束されているため、当該保持部本体31は前方に傾斜(傾倒)する。   First, as shown in FIG. 5, the caregiver drives the tilt actuator 23 while the care receiver P (not shown in FIG. 5) is seated on the seat surface portion 2, and the second support portion 22 is moved to the first support portion 22. It is slid upward (raised) with respect to the support portion 21. Along with this, the holding part main body 31 connected to the second support part 22 also tries to rise, but since the rising is restrained by the connecting rod 24, the holding part main body 31 is inclined (tilted) forward. To do.

図10(b)に示すように、保持部本体31(上半身保持部30)がある程度の角度まで前方に傾斜すると、被介護者Pの体重は、主に上半身保持部30及び膝保持部100によって支えられることになる。この状態で、前述と同様に昇降部材90及び保持部材70による座面部2の保持を解除することで、当該座面部2を本体部1から取り外すことができる。この状態のまま、介助者は被介護者Pが下半身に身につけている衣服を容易にずらしたり、着脱させたりすることができる。   As shown in FIG. 10B, when the holding body 31 (upper body holding part 30) is tilted forward to a certain angle, the weight of the cared person P is mainly determined by the upper body holding part 30 and the knee holding part 100. It will be supported. In this state, the seat surface portion 2 can be removed from the main body portion 1 by releasing the holding of the seat surface portion 2 by the elevating member 90 and the holding member 70 in the same manner as described above. In this state, the caregiver can easily shift or remove the clothes worn by the care recipient P on the lower body.

なお、図10(b)に示すように、座面部2を取り外す際の被介護者Pの大腿部Tの長手方向の角度θ(地面(水平面)に垂直な方向Vに対する角度)は、±30度の範囲内とすることが望ましい。これによって、被介護者Pの大腿部T(大腿骨)の長手方向が地面に対して垂直に近い角度になり、当該大腿部Tを介して被介護者Pの骨盤が支持されることになる。したがって、被介護者Pの胸部や腹部(上半身保持部材33で支持された部分)への圧迫感を低減することができ、被介護者Pは自らの体重を楽に支えることができる。   In addition, as shown in FIG.10 (b), angle θ (angle with respect to the direction V perpendicular | vertical to the ground (horizontal plane)) of the longitudinal direction of the thigh T of the care receiver P when removing the seat surface portion 2 is ± It is desirable to be within the range of 30 degrees. As a result, the longitudinal direction of the thigh T (femur) of the cared person P becomes an angle close to perpendicular to the ground, and the pelvis of the cared person P is supported through the thigh T. become. Therefore, it is possible to reduce the feeling of pressure on the chest or abdomen of the cared person P (part supported by the upper body holding member 33), and the cared person P can easily support his / her weight.
