 (2.昇降カバー33の上部付近の構造)
 次に、昇降カバー33の上部付近の構造について詳述する。図4は、昇降カバー33の上部付近の構造を示す部分斜視図である。また、図5は、揺動アーム部材41の外周に組み付けられたシート部材7を説明する部分斜視図である。図4に示されるように、昇降カバー33の上面331は、後側が低い傾斜平面部332の後側に、曲面部333が連続して形成されている。曲面部333は、前後方向の中間で急峻に屈曲しており、後端が下方に向かっている。
(2. Structure near the top of the lifting cover 33)
Next, the structure near the upper portion of the lifting cover 33 will be described in detail. FIG. 4 is a partial perspective view showing a structure in the vicinity of the upper portion of the elevating cover 33. FIG. 5 is a partial perspective view for explaining the sheet member 7 assembled on the outer periphery of the swing arm member 41. As shown in FIG. 4, the upper surface 331 of the elevating cover 33 has a curved surface portion 333 continuously formed on the rear side of the inclined flat surface portion 332 having a lower rear side. The curved surface portion 333 is bent sharply in the middle in the front-rear direction, and the rear end is directed downward.
 傾斜平面部332から曲面部333の後端にかけて、矩形の開口部36が形成されている。開口部36は、左右方向の中央に位置して、前後方向に長い。揺動アーム部材41は、開口部36の中を前後方向に揺動する。したがって、揺動アーム部材41と開口部36の前縁との間に前側隙間361が生じ、揺動アーム部材41と開口部36の後縁との間に後側隙間362(図6に示す)が生じる。また、揺動アーム部材41と、開口部36の右縁および左縁との間の側部隙間は、ごく僅かとなっている。 A rectangular opening 36 is formed from the inclined flat surface portion 332 to the rear end of the curved surface portion 333. The opening 36 is located in the center in the left-right direction and is long in the front-rear direction. The swing arm member 41 swings in the opening 36 in the front-rear direction. Therefore, a front gap 361 is formed between the swing arm member 41 and the front edge of the opening 36, and a rear gap 362 (shown in FIG. 6) is formed between the swing arm member 41 and the rear edge of the opening 36. Occurs. Further, the side gap between the swing arm member 41 and the right and left edges of the opening 36 is very small.
 開口部36の内面側に、ガイド部材37が配置されている。ガイド部材37は、開口部36の全体よりも大きな矩形の板状に形成され、揺動アーム部材41が通り抜ける矩形孔を中央に有する。ガイド部材37は、昇降部材31または昇降カバー33に固定取り付けされ、概ね上面331に並行して屈曲している。これにより、上面331とガイド部材37との間に、概ね一定の間隙寸法の移動スペースが区画される。移動スペースの間隙寸法は、次に説明するシート部材7の厚みに対して余裕を有するように設定されている。 A guide member 37 is disposed on the inner surface side of the opening 36. The guide member 37 is formed in a rectangular plate shape larger than the entire opening 36 and has a rectangular hole through which the swing arm member 41 passes. The guide member 37 is fixedly attached to the elevating member 31 or the elevating cover 33 and is bent substantially in parallel with the upper surface 331. As a result, a moving space having a substantially constant gap dimension is defined between the upper surface 331 and the guide member 37. The gap size of the moving space is set so as to have a margin with respect to the thickness of the sheet member 7 described below.
 移動スペース内に、弾性変形可能なシート部材7が配置される。シート部材7は、例えば合成樹脂製とされ、これに限定されない。図5に示されるように、シート部材7は、揺動アーム部材41の外周に組み付けられ、揺動アーム部材41に沿って移動可能(矢印M参照)に保持されている。シート部材7は、その外形が前後方向に長い矩形であり、左右方向の幅がガイド部材37よりも狭く、開口部36よりも広い。シート部材7は、開口部36の全体に延伸して配置される。揺動アーム部材41の前後方向の揺動に伴い、シート部材7は、移動スペース内を前後方向に揺動し、その際に弾性変形しつつ、かつ揺動アーム部材41に沿って移動する。これにより、シート部材7は、開口部36の周縁に沿って揺動でき、前側隙間361、後側隙間362、および側部隙間を常に塞ぐことができる。シート部材7は、本発明の閉塞部材の一実施例である。 The elastically deformable sheet member 7 is disposed in the moving space. The sheet member 7 is made of, for example, a synthetic resin, and is not limited to this. As shown in FIG. 5, the sheet member 7 is assembled to the outer periphery of the swing arm member 41 and is held so as to be movable along the swing arm member 41 (see arrow M). The sheet member 7 is a rectangle whose outer shape is long in the front-rear direction, and the width in the left-right direction is narrower than the guide member 37 and wider than the opening 36. The sheet member 7 is disposed so as to extend over the entire opening 36. As the swing arm member 41 swings in the front-rear direction, the seat member 7 swings in the moving space in the front-rear direction, and moves along the swing arm member 41 while being elastically deformed. Accordingly, the sheet member 7 can swing along the periphery of the opening 36 and can always block the front gap 361, the rear gap 362, and the side gap. The sheet member 7 is an embodiment of the closing member of the present invention.
 図6は、後方に揺動した揺動アーム部材41と開口部36の後縁との間の後側隙間362を例示した図である。図示される後側隙間362の最小寸法Gmは、昇降カバー33を形成する板材の厚さの3倍以上に設定されている。例えば、図6の例で、昇降カバー33は厚さ1mmの鋼板で形成され、後側隙間362の最小寸法Gmは、10mm程度に設定されている。前方に揺動した揺動アーム部材41と開口部36の前縁との間の前側隙間361の最小寸法も、同様に10mm程度に設定されている。 FIG. 6 is a diagram illustrating the rear gap 362 between the swing arm member 41 swinging rearward and the rear edge of the opening 36. The minimum dimension Gm of the rear gap 362 shown in the figure is set to be three times or more the thickness of the plate material forming the lifting cover 33. For example, in the example of FIG. 6, the elevating cover 33 is formed of a 1 mm thick steel plate, and the minimum dimension Gm of the rear gap 362 is set to about 10 mm. Similarly, the minimum dimension of the front gap 361 between the swinging arm member 41 swinging forward and the front edge of the opening 36 is also set to about 10 mm.
 (3.実施形態の介助装置1の使用方法および作用)
 次に、実施形態の介助装置1の使用方法および作用について説明する。以降では、椅子Cに座っている被介助者Mが起立動作を行う場合を例にして説明する。仮に介助装置1が遠くにある場合、介助者は、前以て介助装置1を被介助者Mの近くまで移動させておく。座位姿勢の被介助者Mは、まず介助装置1を引き寄せる。すると、図2に示されるように、被介助者Mの両脚は、保持部材5の下側に入り込む。ここで、保持部材5が邪魔になる場合、被介助者Mは、保持部材5の下端部を手または膝で持ち上げる。これにより、保持部材5は、前方に傾動する。被介助者Mは、次に、両足を接地マーク241の上に乗せる。被介助者Mの下腿は、下腿当て部25に接触し、または接近する。
(3. Usage method and operation of the assistance device 1 of the embodiment)
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 gets in the way, the person being assisted lifts the lower end of the holding member 5 with a hand or knee. As a result, the holding member 5 tilts forward. 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.
 次に、被介助者Mは、制御部6の起立補助プログラムの初期動作ルーチンを始動させる。これにより、被介助者Mの体格に合わせて、昇降部材31の高さが自動調整される。次に、被介助者Mは、上半身を胴体受部52に寄りかからせ、両腕を脇受部53の上から前方に出す。さらに、被介助者Mは、両手でハンドル43をそれぞれ把持する。これにより、図2に示された被介助者Mの座位状態となる。座位状態において、被介助者Mの上半身は、少し前傾した姿勢となる。 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 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.
 続いて、被介助者Mは、起立補助プログラムの起立補助ルーチンを始動させる。これにより、昇降部材31の上下動と、揺動アーム部材41の前方への揺動とが協調して行われる。起立補助プログラムが終了した時点で、昇降部材31は上昇し、揺動アーム部材41は前方へ揺動して、図3に示された被介助者Mの立位姿勢となる。立位姿勢において、被介助者Mの上半身は、大きく前傾した姿勢となる。 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. 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 shown in FIG. In the standing posture, the upper body of the person being assisted M is in a largely forward leaning posture.
 被介助者Mの着座動作については、概ね起立動作の逆の動作となるので、説明は省略する。なお、上述した被介助者Mの一連の起立動作の一部は、介助者が介助してもよく、あるいは介助者が代行してもよい。 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.
 上記した被介助者Mの起立動作において、揺動アーム部材41は後方から前方に揺動する。逆に、被介助者Mの着座動作において、揺動アーム部材41は前方から後方に揺動する。ここで、揺動アーム部材41の位置に関係なく、前側隙間361、後側隙間362、および側部隙間は、シート部材7によって常に塞がれている。したがって、被介助者Mの身体や衣服などが開口部36に挟まれることは無い。 In the standing operation of the person being assisted M described above, the swing arm member 41 swings from the rear to the front. Conversely, in the sitting operation of the person being assisted M, the swing arm member 41 swings from the front to the rear. Here, regardless of the position of the swing arm member 41, the front gap 361, the rear gap 362, and the side gap are always closed by the sheet member 7. Therefore, the body, clothes, etc. of the person being assisted M are not sandwiched between the openings 36.
 一方、従来技術の介助装置1Xでは、挟み込みのおそれが解消されていない。図7は、従来技術の介助装置1Xにおいて、揺動アーム部材41の後方揺動時に発生する挟み込みのおそれを説明する部分斜視図である。また、図8は、従来技術の介助装置1Xにおいて、揺動アーム部材41の前方揺動時に発生する挟み込みのおそれを説明する部分斜視図である。従来技術の介助装置1Xは、ガイド部材37やシート部材7を備えず、後側隙間362の最小寸法Gmや、前側隙間361の最小寸法も確保されていない。 On the other hand, in the conventional assistance device 1X, the possibility of pinching has not been resolved. FIG. 7 is a partial perspective view for explaining the possibility of pinching that occurs when the swing arm member 41 swings backward in the conventional assistance device 1X. FIG. 8 is a partial perspective view for explaining the possibility of pinching that occurs when the swing arm member 41 swings forward in the conventional assisting device 1X. The assisting device 1X of the prior art does not include the guide member 37 and the sheet member 7, and the minimum dimension Gm of the rear gap 362 and the minimum dimension of the front gap 361 are not ensured.
 このため、図7に示されるように、揺動アーム部材41が後方に揺動するにつれて後側隙間362が徐々に減少するとき、仮に被介助者Mの身体や衣服などが後側隙間362に進入していると、挟まれてしまう。同様に、図8に示されるように、揺動アーム部材41が前方に揺動するにつれて前側隙間361が徐々に減少するとき、仮に被介助者Mの身体や衣服などが前側隙間361に進入していると、挟まれてしまう。 For this reason, as shown in FIG. 7, when the rear gap 362 gradually decreases as the swing arm member 41 swings backward, the body, clothes, etc. of the person being assisted M are temporarily placed in the rear gap 362. If you are entering, you will be pinched. Similarly, as shown in FIG. 8, when the front gap 361 gradually decreases as the swing arm member 41 swings forward, the body, clothes, etc. of the person being assisted temporarily enter the front gap 361. If it is, it will be pinched.
 これに対し、本実施形態では、シート部材7は、被介助者Mの身体や衣服などが後側隙間362および前側隙間361に進入することを防止するので、挟み込みのおそれは無い。さらに、後側隙間362の最小寸法Gmおよび前側隙間361の最小寸法が確保されている。これにより、昇降カバー33の小口と揺動アーム部材41との間の挟み込みも、無くなる。 On the other hand, in the present embodiment, the seat member 7 prevents the body or clothes of the person being assisted M from entering the rear gap 362 and the front gap 361, so there is no possibility of being caught. Further, the minimum dimension Gm of the rear gap 362 and the minimum dimension of the front gap 361 are secured. Thereby, the pinching between the small opening of the lifting cover 33 and the swing arm member 41 is also eliminated.
 (4.実施形態の介助装置1の態様および効果)
 実施形態の介助装置1は、基台2と、基台2に上下動可能に支持された昇降部材31と、一端411が昇降部材31に揺動可能に支持された揺動アーム部材41と、揺動アーム部材41の他端412に支持されて被介助者Mの上半身を保持する保持部材5と、昇降部材31および揺動アーム部材41の一端411を覆い、かつ揺動アーム部材41が通り抜ける開口部36を有して、昇降部材31と共に昇降する昇降カバー33と、開口部36の周縁と揺動アーム部材41との間の隙間を塞ぐ閉塞部材(シート部材7)と、を備えた。

 さらに、開口部36は、昇降カバー33の曲面部333に形成されており、閉塞部材は、揺動アーム部材41の外周に組み付けられて開口部36の全体に延伸する弾性変形可能なシート部材7であり、昇降部材31または昇降カバー33は、揺動アーム部材41とともに揺動するシート部材7を開口部36の周縁に沿わせるガイド部材37を有する。これによれば、簡易な構成を用いて開口部36を塞ぐことができ、コストの増加が抑制される。 Further, the opening 36 is formed in the curved surface portion 333 of the elevating cover 33, and the closing member is assembled to the outer periphery of the swing arm member 41 and stretched over the entire opening 36 to be elastically deformable. The elevating member 31 or the elevating cover 33 includes a guide member 37 that causes the sheet member 7 that swings together with the swing arm member 41 to run along the periphery of the opening 36. According to this, the opening part 36 can be closed using a simple configuration, and an increase in cost is suppressed.
 さらに、シート部材7は、揺動アーム部材41に沿って移動可能に保持され、揺動アーム部材41の揺動に伴い揺動アーム部材41に沿って移動する。これによれば、開口部36の形状に合わせてシート部材7が自在に移動できるので、本発明を実施可能な開口部36の形状の範囲が広い。 Furthermore, the sheet member 7 is held so as to be movable along the swing arm member 41, and moves along the swing arm member 41 as the swing arm member 41 swings. According to this, since the sheet member 7 can freely move in accordance with the shape of the opening 36, the range of the shape of the opening 36 in which the present invention can be implemented is wide.
 さらに、揺動アーム部材41は、保持部材5に保持された被介助者Mの前後方向に揺動し、前方に揺動した揺動アーム部材41と開口部36の前縁との間、および後方に揺動した揺動アーム部材41と開口部36の後縁との間に、昇降カバー33を形成する板材の厚さの3倍以上の隙間が確保されている。換言すると、後側隙間362の最小寸法Gm、および前側隙間361の最小寸法は、板材の厚さの3倍以上に設定されている。これによれば、昇降カバー33の開口部36の小口と揺動アーム部材41との間に、被介助者Mの身体や衣服などが挟まれることも無くなる。 Further, the swing arm member 41 swings in the front-rear direction of the person being assisted M held by the holding member 5, between the swing arm member 41 swinging forward and the front edge of the opening 36, and Between the swing arm member 41 swinging rearward and the rear edge of the opening 36, a gap of at least three times the thickness of the plate material forming the lifting cover 33 is secured. In other words, the minimum dimension Gm of the rear gap 362 and the minimum dimension of the front gap 361 are set to three times or more the thickness of the plate material. Accordingly, the body or clothes of the person being assisted M is not sandwiched between the small opening of the opening 36 of the lifting cover 33 and the swing arm member 41.
 (5.実施形態の変形および応用)
 なお、ガイド部材37を開口部36の外面側に配置して、上面331の外側にシート部材7の移動スペースを区画することもできる。また、揺動アーム部材41に対して保持部材5が自由傾動しない構成であっても、同様の効果が生じる。さらに、基台2やハンドル43の形状は適宜変更できる。本発明は、その他にも様々な変形や応用が可能である。
