Description

この発明は、介護等が必要な人の身体を保持する抱き締め腕部を有する移乗支援器具に関する。   The present invention relates to a transfer assist device having a hugging arm for holding a body of a person who needs care or the like.

従来、介護者が、高齢者・足腰が弱い人・障害のある人等、介護が必要な被介護者を介護するとき、介護者が被介護者をベッドから車椅子やトイレ等に移す移乗作業が行われている。このような移乗作業は、介護者が腰を屈めて両腕を被介護者の腋の下から背中に回し、抱き締めながら被介護者を少し立たせ、被介護者の体の向きを変えて座らせるものである。しかし、被介護者を抱き締めて立たせたり座らせたりする動作は、介護者に被介護者の体重がかかるため、介護者にとっては負担が大きく、腰痛等が発生しやすいものであった。   Conventionally, when a caregiver cares for a cared person who needs care, such as an elderly person, a person with a weak leg, a person with a disability, etc., the caregiver has moved from the bed to a wheelchair or toilet, etc. Has been done. In such a transfer work, the caregiver bends his waist and turns his arms from the arm of the cared person to the back, while holding the cared person a little while standing and changing the body direction of the cared person. is there. However, the operation of hugging a person to be cared and standing or sitting takes a caregiver's weight, which is heavy for the carer and easily causes back pain or the like.

そこで、介護者の移乗作業の負担を軽減するための移乗器が提案されている。例えば、特許文献１に開示されている移乗支援器具は、シャフトと、シャフトの上端部にあり器具の前後左右の動きを担うハンドルと、シャフトの下端部にあり床面に当接する接地部材と、シャフトの途中から側方に突出して設けられ被介護者の身体の前側を受ける身体保持部材が設けられている。身体保持部材は、被介護者の胸部を支える胴体保持軸部と、腋部を支える腋下保持部が設けられている。接地部材は、身体保持部材の突出方向に対して平行な方向に床面上を転がる曲線を有して形成されている。この転がる方向は、人体を左右に分断する平面であって正中線を通る平面である正中矢状面と平行な方向である。   Therefore, a transfer device has been proposed for reducing the burden of the caregiver's transfer work. For example, a transfer assist device disclosed in Patent Document 1 includes a shaft, a handle that is at the upper end portion of the shaft and that is responsible for the back and forth movement of the device, a grounding member that is at the lower end portion of the shaft and contacts the floor surface, A body holding member is provided that protrudes laterally from the middle of the shaft and receives the front side of the body of the care recipient. The body holding member is provided with a torso holding shaft portion that supports the chest of the care recipient and an armpit holding portion that supports the buttocks. The grounding member is formed with a curve that rolls on the floor surface in a direction parallel to the protruding direction of the body holding member. This rolling direction is a direction parallel to the median sagittal plane that is a plane that divides the human body into left and right and that passes through the midline.

この移乗支援器具の使用方法は、ベッド等の端に座っている被介護者の身体を身体保持部材で支え、介護者がハンドルに力を加えて移乗支援器具を回転させることで、被介護者の身体を抱き上げ、立位を取らせるものである。この際、接地部材の底面形状に合わせて、器具が介護者側に移動し、立位状態になった被介護者を、接地部材の底面形状の湾曲部を支点にして、ハンドル操作で方向転換させ、抱き上げと逆の手順で抱き下ろして、移乗を行うものである。このとき立位を取っていることと、介護者側に引き出された姿勢により、車椅子等の手すりを容易に乗り越えることができる。   The method of using this transfer support device is to support the body of a cared person sitting at the end of a bed or the like with a body holding member, and the caregiver applies force to the handle to rotate the transfer support apparatus, so that the cared person I will lift up my body and take a standing position. At this time, according to the bottom shape of the grounding member, the device moves to the caregiver side and changes the direction of the care recipient who is in the standing position by operating the handle with the curved portion of the bottom shape of the grounding member as a fulcrum. Then, it is transferred by carrying it in the reverse order of lifting. At this time, it is possible to easily get over a handrail such as a wheelchair due to the standing position and the posture drawn to the caregiver.

また、特許文献２に開示されている移乗支援器具は、シャフトとハンドル、接地部材が設けられ、シャフトの途中には人体把持具が設けられている。人体把持具は、被介護者の胸部を支える胸当て板と、胸当て板の上下方向に自由に回転できるように取り付けられ移乗の際に人体を抱きしめるように支える腋支えアームが設けられている。腋支えアームは被介護者の腋と背中を抱えられるようなＬ字構造となっており、取り付けられたレバーで左右に開閉可能であり、身体を左右から挟み込むように操作可能なものである。   Moreover, the transfer assistance instrument disclosed in Patent Document 2 is provided with a shaft, a handle, and a grounding member, and a human body gripping tool is provided in the middle of the shaft. The human body gripping tool is provided with a breast support plate that supports the chest of the cared person and a heel support arm that is attached so as to freely rotate in the vertical direction of the breast support plate and supports the human body during transfer. The heel support arm has an L-shaped structure that can hold the caregiver's heel and back, can be opened and closed left and right with an attached lever, and can be operated so as to sandwich the body from the left and right.

この移乗支援器具の使用方法は、まず腋支えアームをレバーにより操作して被介護者の身体を左右から抱き締める。次に、シャフトをハンドルで動かして被介護者の身体を抱き上げるように操作すると、腋支えアームを上下方向に回転させるための軸周りに、被介護者の体重によるモーメントが発生して、自動的に背中側から胸方向へ体を抱き締め、しっかりと支えることができる。即ち被介護者の体重の分力を利用して体を抱き締めるものである。   In this method of using the transfer assist device, first, the arm of the cared person is hugged from the left and right by operating the armrest support arm with a lever. Next, if you move the shaft with the handle to lift the cared person's body, a moment due to the cared person's weight is generated around the axis for rotating the armrest support arm up and down, and automatically The body can be hugged from the back to the chest and supported firmly. In other words, the body is hugged using the component of the weight of the cared person.

また、特許文献３、特許文献４、特許文献５に開示されている人体移乗装置は、キャスターを有する台座に主柱を立設し、該主柱から傾動可能の枝柱を出し、枝柱の先端に被介護者の身体を保持する保持具が設けられている。さらに、主柱の下部には枝柱の傾動と連結する傾動可能のペダルが設けられ、支柱の上部にはハンドルが設けられているものである。この移乗装置は、リンク機構等で枝柱を傾動可能にして、梃子の原理で被介護者を抱き上げることができる。抱き上げの後は、キャスターを有する台座ごと移動して、逆の動作で抱き下ろし、移乗介助を行うものである。   In addition, the human body transfer devices disclosed in Patent Document 3, Patent Document 4, and Patent Document 5 are provided with a main column standing on a pedestal having casters, and a tiltable branch column is provided from the main column. A holder for holding the cared person's body is provided at the tip. Further, a tiltable pedal connected to the tilt of the branch pillar is provided at the lower part of the main pillar, and a handle is provided at the upper part of the support pillar. This transfer device can tilt the branch pole by a link mechanism or the like, and can lift the cared person by the principle of lever. After the lifting, the pedestal having the casters is moved and hung in the reverse motion to assist the transfer.

上記背景技術の場合、特許文献１の移乗支援器具は、被介護者の身体を抱き締めるように把持する保持具がなく、被介護者の背中側へ器具から脱落する恐れがあった。一方、特許文献２の移乗支援器具は、被介護者の体重の分力を利用して身体を抱きしめていたが、抱き上げや抱き下ろし等の腋支えアームに体重が十分にかかっていない状態では抱き締め効果が小さく不安を感じることがあった。また、腋支えアームの左右の動作は、被介護を受動的に挟み込むものの、被介護者自身が腋を閉じて腋支えアームに乗る被介護者の腕力に頼る部分が大きく、極端に腕力がなくなった被介護者の場合には適用できない可能性があった。また、バネや複数の回転支点を持つため、構造が複雑で重量が大きくなるという問題もあった。   In the case of the above-described background art, the transfer assist device of Patent Document 1 does not have a holding tool that holds the cared person's body so as to be hugged, and there is a risk that the tool may fall out of the device toward the back side of the cared person. On the other hand, the transfer assist device of Patent Document 2 has hugged the body using the component of the weight of the cared person, but is hugging when the weight is not sufficiently applied to the armrest support arm such as lifting or hugging. The effect was small and I felt uneasy. In addition, although the left and right movements of the heel support arm passively pinch the caregiver, the care receiver himself closes the heel and relies heavily on the arm strength of the care receiver who rides on the heel support arm, and the arm strength is extremely lost It may not be applicable in the case of a care recipient. Further, since the spring and the plurality of rotation fulcrums are provided, there is a problem that the structure is complicated and the weight is increased.

特許文献３〜５に開示された人体移乗装置は、被介護者の身体を抱き締めるように把持する保持具がなく、不安定なものであった。特許文献３には、身体の背面を巻くベルトが設けられているが、一回毎にベルトを締めるため作業効率が良くないものであった。更に、特許文献３〜５の人体移乗装置は、キャスター付きの台車やストッパ等の付帯部品を備えるため、重量が重く、そのままで容易に持ち運ぶことが困難であった。   The human body transfer devices disclosed in Patent Documents 3 to 5 are unstable because there is no holding tool for holding the body of the care recipient so as to hug. In Patent Document 3, a belt that wraps around the back of the body is provided, but the work efficiency is not good because the belt is fastened each time. Furthermore, since the human body transfer apparatuses of Patent Documents 3 to 5 are provided with accessory parts such as a cart with a caster and a stopper, they are heavy and difficult to carry as they are.

この発明は、上記背景技術の問題点に鑑みてなされたものであり、簡単な構造で手軽に利用可能であり、安全且つ確実に移乗作業を補助することができる移乗支援器具を提供することを目的とする。   The present invention has been made in view of the above-described problems of the background art, and provides a transfer support device that can be easily used with a simple structure and can assist a transfer operation safely and reliably.

以下、この発明の実施形態について図面に基づいて説明する。図１〜図７はこの発明の一実施形態を示すもので、この実施形態の移乗支援器具１０は、中心に適度な強度を有する金属製のシャフト１２が設けられ、シャフト１２の上端部１２ａには介護が必要な被介護者４６の身体の前側を受ける腹当て部１４が設けられている。腹当て部１４は、シャフト１２の先端部から直角に交差して連結された棒状の腹当て部材１６と、腹当て部材１６に巻き付けられたクッション１８が設けられている。なお、シャフト１２の上端部１２ａは、腹当て部１４の長手方向の中心に連結されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 show an embodiment of the present invention. A transfer support device 10 of this embodiment is provided with a metal shaft 12 having an appropriate strength at the center, and an upper end portion 12 a of the shaft 12. Is provided with a belly pad 14 for receiving the front side of the body of the care recipient 46 who needs care. The belly pad 14 is provided with a rod-shaped bell pad 16 that is connected at right angles from the tip of the shaft 12, and a cushion 18 wound around the bell pad 16. Note that the upper end portion 12 a of the shaft 12 is connected to the center in the longitudinal direction of the belly pad portion 14.

腹当て部材１６の両端部には、被介護者４６の身体の腋の下を受ける一対の抱き締め腕部２０が設けられている。抱き締め腕部２０は、腹当て部１４の長手方向に対して後述するように、所定角度θ傾斜して設けられた軸周りに回転可能に軸止されている。一対の抱き締め腕部２０の幅は、被介護者４６の胴体の両腋の幅とほぼ等しいか、若干大きいものである。   A pair of hugging arms 20 that receive the armpit of the body of the cared person 46 are provided at both ends of the belly pad 16. As will be described later with respect to the longitudinal direction of the belly pad 14, the hugging arm 20 is pivotally supported so as to be rotatable about an axis provided at a predetermined angle θ. The width of the pair of hugging arm portions 20 is substantially the same as or slightly larger than the width of both sides of the body of the cared person 46.

抱き締め腕部２０は、腹当て部１４の両端部に、腹当て部１４の長手方向に対して、所定角度θで、軸周りに回転可能に軸止された縦軸部２２と、縦軸部２２の先端部に直角に固定された横軸部２４と、横軸部２４の先端部に直角に固定され縦軸部２２に対して平行に下方に向かって突出する背当て軸部２６が設けられている。   The hugging arm portion 20 includes a vertical axis portion 22 that is rotatably supported around an axis at a predetermined angle θ with respect to the longitudinal direction of the belly pad portion 14 at both ends of the belly pad portion 14, and a vertical axis portion There are provided a horizontal shaft portion 24 fixed at a right angle to the front end portion of 22 and a back shaft portion 26 fixed at a right angle to the front end portion of the horizontal shaft portion 24 and projecting downward in parallel to the vertical axis portion 22. It has been.

ここで所定角度θは、一対の抱き締め腕部２０が、回転した時に被介護者４６の胴体を抱き締める方向に開閉するよう設定すればよい。例えば、シャフト１２を鉛直方向に対して３０°傾斜させて、腹当て部１４が被介護者４６の下腹部に当接している状態において、所定角度θは、水平面に平行な面上で、腹当て部１４の長手方向に対して、例えば３０°に設定すればよい。また、抱き締め腕部２０の回転軸が腹当て部１４の長手方向に対して傾斜していることにより、抱き締め腕部２０が回転すると、被介護者４６の胴体幅が違っていても、被介護者４６の胴体および背中に当接する位置で静止し、胴体を良好に抱き締めるように支えることができる。   Here, the predetermined angle θ may be set so that the pair of hugging arms 20 opens and closes in the direction of hugging the body of the cared person 46 when rotated. For example, in a state where the shaft 12 is inclined by 30 ° with respect to the vertical direction and the belly pad 14 is in contact with the lower abdomen of the cared person 46, the predetermined angle θ is set on the surface parallel to the horizontal plane. What is necessary is just to set to 30 degrees with respect to the longitudinal direction of the contact part 14, for example. Moreover, even if the body width of the cared person 46 is different when the hugging arm part 20 is rotated because the rotation axis of the hugging arm part 20 is inclined with respect to the longitudinal direction of the belly pad part 14, The person 46 can rest at a position where it abuts against the body and back of the person 46, and can support the body so as to hug it well.

横軸部２４の先端は、被介護者４６の身体に沿うように折り曲げられている。そして縦軸部２２、横軸部２４、背当て軸部２６には、一枚のシート２８が掛け渡されて張られた状態で取り付けられている。   The tip of the horizontal shaft portion 24 is bent along the body of the care recipient 46. Then, a single sheet 28 is stretched and attached to the vertical axis portion 22, the horizontal axis portion 24, and the backrest shaft portion 26.

シート２８は異形の矩形であり、縦軸部２２、横軸部２４、背当て軸部２６に巻き回して取り付けられる面ファスナー等の係止手段が設けられている。抱き締め腕部２０のシート２８と、腹当て部１４のクッション１８は、例えば同様のメッシュの素材で作られている。   The seat 28 has an odd-shaped rectangle, and is provided with locking means such as a hook-and-loop fastener that is wound around and attached to the vertical axis portion 22, the horizontal axis portion 24, and the backrest shaft portion 26. The seat 28 of the hugging arm 20 and the cushion 18 of the belly pad 14 are made of, for example, the same mesh material.

抱き締め腕部２０には、Ｌ字形のハンドル３０が各々設けられている。ハンドル３０は、横軸部２４の延長上に縦軸部２２を超えて突出し、Ｌ字形に下方に折り曲げられている。   Each of the hugging arms 20 is provided with an L-shaped handle 30. The handle 30 protrudes beyond the vertical axis 22 on the extension of the horizontal axis 24 and is bent downward in an L shape.

シャフト１２の下端部１２ｂに近い部分には、複数の透孔３１がシャフト１２に沿って形成されている。シャフト１２の下端部１２ｂには、床面に当接する接地部材３２が設けられている。接地部材３２は、シャフト１２の下端部１２ｂが差し込まれる円筒部３４と、円筒部３４の下端部３４ａに固定されたパイプ３６が設けられている。円筒部３４には、シャフト１２の透孔３１に連通する透孔が形成され、高さ調整部材３８が挿通されている。これにより、シャフト１２のいずれかの透孔３１に、円筒部３４の透孔を一致させて高さ調整部材３８で連結し、シャフト１２と接地部材３２を任意の長さで連結する。   A plurality of through holes 31 are formed along the shaft 12 in a portion near the lower end portion 12 b of the shaft 12. A grounding member 32 that abuts against the floor surface is provided at the lower end 12 b of the shaft 12. The grounding member 32 is provided with a cylindrical portion 34 into which the lower end portion 12 b of the shaft 12 is inserted, and a pipe 36 fixed to the lower end portion 34 a of the cylindrical portion 34. A through hole communicating with the through hole 31 of the shaft 12 is formed in the cylindrical portion 34, and a height adjusting member 38 is inserted therethrough. Thereby, the through-hole of the cylindrical part 34 is made to correspond to any through-hole 31 of the shaft 12, and it connects with the height adjustment member 38, and the shaft 12 and the grounding member 32 are connected by arbitrary length.

パイプ３６は、腹当て部１４の長手方向に直角に交差する垂直面上に位置する円弧状に曲げられている。円筒部３４の下端部３４ａは、パイプ３６の中心よりも抱き締め腕部２０が突出する方向の反対の端部３６ａに近い位置に、円弧状の内周側で固定されている。パイプ３６の端部３６ａには、後述する介護者４８が使用する足踏み用のペダル部４２が取り付けられている。円筒部３４の途中には、端部３６ａと反対側の端部３６ｂに近い位置に、斜めに補強棒４０が連結されて設けられている。   The pipe 36 is bent in an arc shape located on a vertical plane that intersects the longitudinal direction of the belly pad 14 at a right angle. The lower end portion 34 a of the cylindrical portion 34 is fixed on the arcuate inner peripheral side at a position closer to the end portion 36 a opposite to the direction in which the hugging arm portion 20 protrudes than the center of the pipe 36. A pedal part 42 for stepping used by a caregiver 48 described later is attached to the end 36a of the pipe 36. In the middle of the cylindrical portion 34, a reinforcing rod 40 is obliquely connected and provided at a position near the end portion 36b opposite to the end portion 36a.

次に、この実施形態の移乗支援器具１０の使用方法について説明する。まず、一対の抱き締め腕部２０の動作について図５、図６に基づいて説明する。一対の抱き締め腕部２０は、ハンドル３０を操作することにより、腹当て部材１６の延長線に対して交差（θ＝３０°）する軸周りに回転し、開閉する。これにより、一対の抱き締め腕部２０は、図５に示すようにハンドル３０を介護者４８が手で上げると、抱き締め腕部２０の先端は互いに離れて開く。また、図６に示すようにハンドル３０を手で下げると、抱き締め腕部２０の先端は互いに近付いて閉じる。この動作を利用して、被介護者４６を保持し、移乗操作を行う。   Next, the usage method of the transfer assistance instrument 10 of this embodiment is demonstrated. First, operation | movement of a pair of hugging arm part 20 is demonstrated based on FIG. 5, FIG. The pair of hugging arm portions 20 are rotated around an axis intersecting (θ = 30 °) with respect to the extension line of the abdomen support member 16 by operating the handle 30 to open and close. Thereby, when the caregiver 48 raises the handle 30 by hand as shown in FIG. 5, the tip ends of the pair of hugging arms 20 are opened apart from each other. Further, when the handle 30 is lowered by hand as shown in FIG. 6, the tips of the hugging arm portions 20 approach each other and close. Using this action, the care receiver 46 is held and a transfer operation is performed.

ここでは、図３に示すように、ベッドや椅子４４に腰掛けている被介護者４６を、図４に示すように椅子４４から立たせて、椅子４４近傍に置いた図示しない車椅子などに座らせる場合について説明する。まず、被介護者４６の前に、移乗支援器具１０のハンドル３０を持って介護者４８が立ち、移乗支援器具１０の抱き締め腕部２０を被介護者４６に向ける。そして、ハンドル３０を被介護者４６側に傾けて、シャフト１２を倒して抱き締め腕部２０を被介護者４６に近付ける。次にシャフト１２の位置を変えずに図５に示すように一対のハンドル３０を上げて、被介護者４６腋の幅に合わせて抱き締め腕部２０を開き、被介護者４６の腋の下に差し込む。同時に腹当て部１４を被介護者４６の腹部に当接させる。この後、ハンドル３０を下げて、抱き締め腕部２０の幅が狭くなるとともに、斜め下方に下がって被介護者４６の背中に当接し、腹当て部１４と一対の抱き締め腕部２０で被介護者４６の上半身を適度な力で締める。   In this case, as shown in FIG. 3, a cared person 46 sitting on a bed or chair 44 stands up from the chair 44 as shown in FIG. 4 and sits on a wheelchair (not shown) placed near the chair 44. Will be described. First, the caregiver 48 stands with the handle 30 of the transfer assist device 10 in front of the care recipient 46 and points the hugging arm portion 20 of the transfer assist device 10 toward the care receiver 46. Then, the handle 30 is tilted toward the cared person 46, the shaft 12 is tilted, and the hugging arm unit 20 is brought closer to the cared person 46. Next, without changing the position of the shaft 12, the pair of handles 30 are raised as shown in FIG. 5, the hugging arm portion 20 is opened in accordance with the width of the cared person 46, and the arm 12 is inserted under the cared person 46. At the same time, the abdomen 14 is brought into contact with the abdomen of the cared person 46. Thereafter, the handle 30 is lowered so that the width of the hugging arm portion 20 is narrowed, and the handle 30 is lowered obliquely downward and comes into contact with the back of the care receiver 46. Tighten the upper body of 46 with moderate force.

この状態で、介護者４８は、接地部材３２のパイプ３６のペダル部材４２に片足を載せて、床に固定しながらハンドル３０を手前に引く。すると、接地部材３２のパイプ３６が床面を揺動し、シャフト１２に接地部材３２を中心としたモーメントが与えられ、シャフト１２が移動する。床周りのモーメントの釣り合いによって、移乗支援器具１０と被介護者４６の重量を支え被介護者４６を押し上げ、椅子４４から離し、図４に示すように被介護者４６は、腹当て部１４と抱き締め腕部２０に締められて体重をかけた状態で椅子４４から立ち上げられる。移乗支援器具１０の左右方向のバランスは、被介護者４６が自身の脚力により支えるが、不足する部分は介護者４８が補う。これにより、被介護者４６は自身の足で一部身体を支えながら移乗支援器具１０にもたれかかるような姿勢で、楽に立ち上がることができる。そして、図示しない車椅子等に後向きに立たせ、移乗支援器具１０を被介護者４６側に傾けて座らせる。このとき、パイプ３６が円弧形状をしているので、移乗支援器具１０全体が被介護者４６の正中矢状面と平行な方向へと転がり出るように回転し、車椅子への移乗の際に障害となる肘かけ部分を避けることができる。   In this state, the caregiver 48 puts one foot on the pedal member 42 of the pipe 36 of the grounding member 32 and pulls the handle 30 forward while fixing it to the floor. Then, the pipe 36 of the grounding member 32 swings on the floor surface, and a moment about the grounding member 32 is given to the shaft 12 so that the shaft 12 moves. Due to the balance of moments around the floor, the weight of the transfer assist device 10 and the cared person 46 is supported, the cared person 46 is pushed up, and separated from the chair 44. As shown in FIG. It is raised from the chair 44 in a state in which it is fastened to the hugging arm portion 20 and is weighted. Although the care receiver 46 supports the balance in the left-right direction of the transfer assisting device 10 with his / her leg power, the caregiver 48 compensates for the shortage. As a result, the cared person 46 can easily stand up in such a posture as to lean against the transfer assisting device 10 while partially supporting his / her body with his / her foot. Then, the wheelchair or the like (not shown) is caused to stand rearward, and the transfer assisting device 10 is tilted toward the care receiver 46 side. At this time, since the pipe 36 has an arc shape, the entire transfer assisting device 10 rotates so as to roll out in a direction parallel to the median sagittal plane of the care recipient 46, which is an obstacle in transferring to the wheelchair. Can avoid the armrest part.

移乗支援器具１０は、使用しないときには、図７に示すように抱き締め腕部２０を、ハンドル３０を下げる方向に回転させてシャフト１２に重ねて畳む。さらに調整ネジ３８を緩め、接地部材３２をパイプ３６が抱き締め腕部２０に対して平行になるようにセットし、シャフト１２に深く差し込んで短くし、コンパクトに畳むことができる。   When the transfer assisting device 10 is not used, the hugging arm portion 20 is rotated in the direction in which the handle 30 is lowered and folded on the shaft 12 as shown in FIG. Further, the adjusting screw 38 is loosened, and the grounding member 32 is set so that the pipe 36 is parallel to the hugging arm portion 20, and is deeply inserted into the shaft 12 to be shortened so that it can be compactly folded.

この実施形態の移乗支援器具１０によれば、簡単な構造で手軽に利用可能であり、確実に移乗作業を補助することができ、さらに、以下の効果を有する。   According to the transfer support device 10 of this embodiment, it can be easily used with a simple structure, can reliably assist the transfer work, and has the following effects.

一対の抱き締め腕部２０は、被介護者４６の胸の一部と腋から背中までを支えるＬ字形をしているため、身体を後左右から挟むように抱き締めて移乗操作を行うことができる。ハンドル３０を動かすだけの簡単な操作で、抱き締め腕部２０で被介護者４６の胸から背中にかけて適度な強さで締め付けて、安定した状態で被介護者４６を保持して移乗作業を行うことができる。また、移乗作業が終了したとき、ハンドル３０を操作して抱き締め腕部２０を開き、被介護者４６から簡単に外すことができる。   Since the pair of hugging arms 20 has an L-shape that supports a part of the chest of the care recipient 46 and the heel to the back, the user can perform a transfer operation by hugging the body from behind and right and left. By simply operating the handle 30, the hugging arm 20 tightens the cared person 46 from the chest to the back with an appropriate strength and holds the cared person 46 in a stable state to perform the transfer operation. Can do. Further, when the transfer operation is completed, the handle 30 can be operated to open the hugging arm portion 20 and be easily removed from the cared person 46.

ハンドル３０は、一対の抱き締め腕部２０の開閉とシャフト１２の傾きの変更の２操作を兼ねて行うことができるため、抱き締め動作後にハンドル３０を持ちかえないまま、ペダル部材４２を踏んでシャフト１２の傾きを変えて回転させ、抱きあげる動作を、ハンドル３０を引くという一つの動作で行うことができ、便利である。さらに、抱きあげに要する力の分力を利用して抱きしめることができ、抱き締める力が強すぎるときは、ペダル部材４２を強く踏んでハンドル３０の引っ張り力を減らすことで抱き締め腕部２０の締め付け力を調節することができる。   Since the handle 30 can be used for both the opening and closing of the pair of hugging arms 20 and the change of the inclination of the shaft 12, the pedal 12 is stepped on while holding the handle 30 after the hugging operation. It is convenient that the operation of rotating and holding up by changing the inclination of the can be performed by one operation of pulling the handle 30. Furthermore, the force of the force required for hugging can be used for hugging. When the hugging force is too strong, the pedal member 42 is strongly stepped on to reduce the pulling force of the handle 30, thereby tightening the hugging arm portion 20. Can be adjusted.

また、この移乗支援器具１０は、介護者４８の人力による操作を基本とし、装置が小形・軽量で可搬性に富むものである。モータ等のアクチュエータを持たないため、価格を低く抑えることができる。車椅子を利用する被介護者４６の活動範囲を広げ、生活の質を改善することができる。介護者４８は、シャフト１２を引き寄せながらハンドル３０を下方に下げて抱き締め腕部２０を上げて被介護者４６を持ち上げることができるため、自分の体重移動が小さくて作業姿勢が楽なように改善され、足腰の重量負荷を軽減し、在宅介護や老老介護を支援することができる。   In addition, the transfer assisting device 10 is based on the operation of the caregiver 48 by human power, and the apparatus is small and light, and is portable. Since there is no actuator such as a motor, the price can be kept low. The range of activities of the cared person 46 using the wheelchair can be expanded and the quality of life can be improved. The caregiver 48 can lift the care receiver 46 by lowering the handle 30 downward while pulling the shaft 12 and lifting the care receiver 46, so that his / her weight shift is small and the work posture is improved. It is possible to reduce the weight load on the legs and to support home care and elderly care.

接地部材３２のパイプ３６が転がることによりシャフト１２が移動し、またハンドル３０で抱き締め腕部２０を上方に移動させることにより被介護者４６の身体を前上方に押し上げ、椅子４６から離れて立ち上がらせることができる。介護者４８が被介護者４６を立たせるときに、介護者４８がのけぞるような姿勢にならず、自然な体勢で操作することができる。さらに、被介護者４６を前方に倒しながら立たせ、回転させた後に被介護者４６を座らせるため、肘掛が付いている椅子や車椅子でも、肘掛が邪魔にならず、円滑に方向を変えることができる。立位を経て移乗を行うため、移乗先の車椅子の種類を問わない利点がある。   When the pipe 36 of the grounding member 32 rolls, the shaft 12 moves, and the body 30 of the cared person 46 is pushed forward and upward by moving the hugging arm portion 20 upward with the handle 30 and is lifted away from the chair 46. be able to. When the caregiver 48 raises the cared person 46, the caregiver 48 does not take a posture to slide and can be operated with a natural posture. Furthermore, since the cared person 46 is placed while being tilted forward and rotated, the cared person 46 can be seated, so even in a chair or a wheelchair with an armrest, the armrest does not get in the way and the direction can be changed smoothly. it can. Since the transfer is performed after standing, there is an advantage regardless of the type of wheelchair of the transfer destination.

また、被介護者４６は足で自分の体重の一部を支えるため、擬似的な立位移乗をすることで、下肢訓練を促しリハビリや介護予防に結びつく効果がある。被介護者４６の足が直接床を踏みしめ、膝を自由に動かすことができ、被介護者４６の意思で身体を支えることができる。被介護者４６の腰を前へ出し、かつ上体の前傾を増して自然な立ち上がり状態に近づけることができる。被介護者４６は介護者４８と協調して移乗支援器具１０の前後左右のバランスをとらなければならず、この点でもリハビリ効果がある。   In addition, since the cared person 46 supports a part of his / her body weight with his / her foot, by performing pseudo standing transfer, training of the lower limbs is promoted, which has an effect of rehabilitation and care prevention. The care receiver 46 can directly step on the floor and freely move the knee, and can support the body with the care recipient 46's intention. The cared person's 46 waist | hip | lumbar can be put forward and the front body inclination can be increased and it can approach a natural standing state. The cared person 46 must balance the front, rear, left and right of the transfer assisting device 10 in cooperation with the carer 48, and this also has a rehabilitation effect.

シャフト１２と、接地部材３２の円筒部３４は、シャフト１２の透孔３１に円筒部３４の透孔を一致させて調整ネジ３８で連結するため、高さ調整が可能であり、介護者４８の身長に合わせて調整することができる。   The shaft 12 and the cylindrical portion 34 of the grounding member 32 are connected to the through-hole 31 of the shaft 12 with the adjustment screw 38 so that the through-hole of the cylindrical portion 34 coincides with the through-hole 31 of the shaft 12. It can be adjusted to your height.

移乗支援器具１０を使用しないときは、コンパクトにたたむことができてかさばることがなく、使用する際は、抱き締め腕部２０が被介護者４６の腰の高さ付近に位置するように調整ネジ３８で高さを調節するだけで、すぐに使用することができ、組み立てにかかる手間が少なく、継続的な利用が可能である。   When the transfer assisting device 10 is not used, it can be folded compactly and is not bulky. When used, the adjustment screw 38 is positioned so that the hugging arm portion 20 is positioned near the waist of the care receiver 46. By simply adjusting the height, it can be used immediately, requiring less time for assembly, and can be used continuously.

なお、この発明の移乗支援器具は、上記実施形態に限定されず、各部材は適宜変更可能である。例えばシャフトにガススプリングやコイルスプリング等の伸縮要素を用いることで、立ち上がり以後の擬似自立状態や擬似自立状態への移行時に、圧縮されたスプリングを開放して容易に起立姿勢に近づけるものでもよい。また、接地部材の形状は円弧などの転がるものであれば適宜変更可能である。転がる形状であれば、円弧以外に放物線、双曲線、サイクロイド曲線、インボリュート曲線などいろいろな曲線群を想定することができる。立ち上がる被介護者の姿勢・身***置の変化に対応した接地部材の底面形状を与えることで、立ち上がり動作に対する追従性をより良くする事も可能である。つまり、底面形状をカム曲線、被介護者の身***置（主に腰）をフォロアの出力として捕らえて身***置の変化を任意に与えることができる。接地部材は、パイプ以外にキャスター等を用いても良い。キャスター等を用いると、同一姿勢での移動が可能となる。被介護者の体重を分散させるためにシャフトに膝当てを設けてもよい。膝当てに被介護者の膝を当てることで、被介護者の足下の負担を減らすことができる。   In addition, the transfer assistance instrument of this invention is not limited to the said embodiment, Each member can be changed suitably. For example, by using an expansion / contraction element such as a gas spring or a coil spring for the shaft, the compressed spring may be released and easily approximated to the standing posture at the time of transition to the pseudo self-standing state or the pseudo self-standing state after the rising. Further, the shape of the grounding member can be appropriately changed as long as it rolls such as an arc. In the case of a rolling shape, various curve groups such as a parabola, a hyperbola, a cycloid curve, and an involute curve can be assumed in addition to an arc. By providing the bottom surface shape of the ground contact member corresponding to changes in the posture and body position of the cared person standing up, it is also possible to improve the followability to the rising motion. That is, it is possible to arbitrarily give a change in the body position by capturing the bottom surface shape as a cam curve and the body position (mainly waist) of the cared person as the output of the follower. As the grounding member, a caster or the like may be used in addition to the pipe. When casters are used, it is possible to move in the same posture. A knee pad may be provided on the shaft to disperse the weight of the cared person. By placing the caregiver's knee on the knee pad, the burden on the caregiver's feet can be reduced.
