Description

本発明は、主として便器を利用した後の要介護者等の立ち上がりを介助する立ち上がり補助装置に関するものである。 The present invention relates to a stand-up assistance device that mainly assists the start-up of a care recipient after using a toilet.

要介護者等が便器を利用する際、便座に着座する時には体の重心が足よりも後方に移動しており、便器を利用した後にその重心が後方に移動した状態から立ち上がるのは、足腰に負担がかかるため要介護者には容易ではない。そこで、便器を利用した後の要介護者等の立ち上がりを介助する装置として従来、例えば特許文献１に記載の便座を水平なまま昇降移動させる便座持ち上げ装置が提案されている。 When a care recipient uses a toilet, the center of gravity of the body moves backward from the foot when sitting on the toilet seat, and after using the toilet, the center of gravity moves backward from the foot. It is not easy for care recipients because of the burden. Therefore, conventionally, as a device for assisting the rising of a care recipient after using the toilet, for example, a toilet seat lifting device for moving up and down the toilet seat described in Patent Document 1 has been proposed.

また、上述の如き介助装置として従来、例えば特許文献２に記載の便座を上昇附勢スプリングで前傾させる便座持ち上げ装置、および特許文献３に記載の便座を左右で支持する四節非平行リンク機構を電動式直線駆動機構で附勢して便座を持ち上げながら前傾させて臀部を押し上げ、重心移動を容易にした便座持ち上げ装置が提案されている。 Conventionally, as the above-described assistance device, for example, a toilet seat lifting device that tilts the toilet seat described in Patent Document 2 forward with a lifting bias spring, and a four-bar non-parallel link mechanism that supports the toilet seat described in Patent Document 3 on the left and right A toilet seat lifting device has been proposed that facilitates the movement of the center of gravity by urging the body with an electric linear drive mechanism and tilting it forward while lifting the toilet seat to push up the buttocks.

その他にも、要介護者の着座および起立補助装置として、例えば特許文献４に記載の着座・起立補助装置が提案されており、この装置では流体圧シリンダの先端にホルダを取付け、該ホルダで要介護者の臀部を下側から支持すると共に要介護者の臀部の移動軌跡に沿ってそのホルダを昇降移動させることにより要介護者の着座および起立動作を補助可能としている。
特許３６８４３０３号公報特開平０９−０８４７２０号公報特開２００２−２９１６５３号公報特開２００３−１７５０８１号公報 In addition, for example, a seating / standing support device described in Patent Document 4 has been proposed as a sitting and standing assistance device for a care recipient, and in this device, a holder is attached to the tip of a fluid pressure cylinder, and the holder needs to be installed. While supporting the caregiver's buttocks from below, the holder can be moved up and down along the movement locus of the caretaker's buttocks to assist the care recipient in sitting and standing.

しかしながら、上記従来の便座持ち上げ装置では便座を持ち上げることにより要介護者等の臀部の持ち上げを補助可能であるものの、便座の上昇位置までしか立ち上がり補助を行うことが出来ない。また、便座の上昇位置から要介護者等が立ち上がるに際しては、要介護者等が自分の重心を前方へと移動させて立ち上がる必要があり、また、要介護者等の後方への転倒を防止する機構が具えられていなかった。 However, although the conventional toilet seat lifting device can assist lifting of the buttocks of a care recipient by lifting the toilet seat, it can only assist to stand up to the raised position of the toilet seat. In addition, when a care recipient, etc. stands up from the raised position of the toilet seat, it is necessary for the care recipient etc. to stand up by moving his / her center of gravity forward, and to prevent the care recipient etc. from falling backward. No mechanism was provided.

また、上記従来の着座および起立補助装置では要介護者等の臀部をホルダで下側から支持して該ホルダを臀部の移動軌跡に沿って昇降移動させることで要介護者等の着座および起立補助が可能であるものの、要介護者等の上体の後方への倒れ（ふらつき）を防止する機構が具えられておらず、また、臀部の下側からホルダを昇降させる構成のために便器とホルダ昇降機構との干渉が発生し易いという問題があった。 In addition, in the conventional seating and standing assistance device described above, sitting and standing assistance for a care recipient etc. are supported by supporting the buttocks of a care recipient from below with a holder and moving the holder up and down along the movement trajectory of the buttocks. However, there is no mechanism to prevent the upper body from falling backward (staggered) such as those requiring care, and the toilet and holder are configured for raising and lowering the holder from below the buttocks. There was a problem that interference with the lifting mechanism was likely to occur.

It is screwed into the screw hole 21i and pivotally supports the tip of the upper link member 15.

これにより、各電動式連結軸移動機構２１は、モータ２１ｅでウオームギヤ２１ｄを回転させてウオームホイール２１ｃひいては回動軸２１ｂを回動させることで、アーム２１ａを揺動させて、図５Ａ，図５Ｂに示すように、脚板１８ａに対し、上側のリンク部材１５と下側のリンク部材１６とが四節平行リンク機構を構成して上板１８ｂひいては便座２を水平姿勢に維持する位置にピン２１ｊを移動させるとともに、図５Ｃに示すように、脚板１８ａに対し、上側のリンク部材１５と下側のリンク部材１６とが四節非平行リンク機構を構成して上板１８ｂひいては便座２を前傾姿勢にする位置にピン２１ｊを移動させ、このピン２１ｊの移動により便座２を水平姿勢と前傾姿勢との間で揺動させる。また、左右の電動式連結軸移動機構２１は、ポテンショメータ２１ｈで回動軸２１ｂの回動角度を検出して制御装置８に送り、これらの回動角度を互いに一致させるように制御装置８はモータ２１ｅを作動させるので、左右の電動式連結軸移動機構２１による便座２の前傾姿勢への傾動角度は一致する。なお、左右の電動式直線駆動機構２０も同様にポテンショメータでモータの回動角度ひいてはロッド２０ｂの進退位置を検出して制御装置８に送り、これらの回動角度を互いに一致させるように制御装置８はモータを作動させるので、左右の電動式直線駆動機構２０による便座２の昇降位置は一致する。そして便座２の前傾姿勢への傾動角度と上昇位置とをそれぞれ示す値は、上記コントローラにより任意に複数種類指定して、制御装置８のメモリ内に記憶させることができる。 As a result, each electric connecting shaft moving mechanism 21 rotates the worm gear 21d by the motor 21e and rotates the worm wheel 21c and thus the rotating shaft 21b, thereby swinging the arm 21a, and FIGS. 5A and 5B. As shown, the upper link member 15 and the lower link member 16 form a four-bar parallel link mechanism with respect to the leg plate 18a, and the pin 21j is placed at a position that maintains the upper plate 18b and thus the toilet seat 2 in a horizontal position. As shown in FIG. 5C, the upper link member 15 and the lower link member 16 form a four-node non-parallel link mechanism, and the upper plate 18b and thus the toilet seat 2 are tilted forward with respect to the leg plate 18a. The pin 21j is moved to the position to be set, and the toilet seat 2 is swung between the horizontal posture and the forward leaning posture by the movement of the pin 21j. Further, the left and right electric connecting shaft moving mechanisms 21 detect the rotation angle of the rotation shaft 21b with a potentiometer 21h and send the rotation angle to the control device 8, and the control device 8 is a motor so that these rotation angles coincide with each other. 21e is actuated, the tilt angles of the toilet seat 2 to the forward leaning posture by the left and right electric connecting shaft moving mechanisms 21 coincide. Similarly, the left and right electric linear drive mechanisms 20 are also detected by a potentiometer to detect the rotation angle of the motor, and hence the forward / backward position of the rod 20b, and send the control device 8 to the control device 8 so that the rotation angles coincide with each other. Since the motor is operated, the lift position of the toilet seat 2 by the left and right electric linear drive mechanisms 20 coincides. A plurality of values indicating the tilt angle of the toilet seat 2 to the forward tilting posture and the raised position can be arbitrarily specified by the controller and stored in the memory of the control device 8.
