JP 2001-346842 A JP 2002-58712 A

発明が解決しようとする課題は、従来の歩行支援装置では、吊りロープの上動時に使用者に衝撃が伝わりやすいという点である。   The problem to be solved by the invention is that, in the conventional walking assistance device, an impact is easily transmitted to the user when the suspension rope moves up.

本発明の歩行支援装置は、支柱と、支柱の上部に支点で上下方向に往復するシーソー運動を行うように取付けられた吊棒と、吊棒の支点よりも後側に位置する他端部に設けられた人体吊下げ点と、吊棒の支点よりも前側に位置する一端部に設けられた機構吊下げ点と、支柱や支柱に連結された装置フレームに取付けられた弾性伸縮機構と、支柱や支柱に連結された装置フレームに取付けられた巻取機構と、一端部が弾性伸縮機構の上部に連結され他端部が人体吊下げ点を経由して巻取機構に連結された吊りロープと、人体吊下げ点より吊り下げられた吊りロープに掛け渡されて上下動可能となった動滑車とを備え、動滑車が人体を吊るための引掛具を備えたことを特徴とする。
吊棒の支点から吊棒の人体吊下げ点までの他端側寸法が、吊棒の支点から吊棒の機構吊下げ点までの一端側寸法よりも長いことも特徴とする。
吊棒が、吊りロープの他端の上方への移動を規制するストッパを備えたことも特徴とする。
The walking support device of the present invention has a support, a suspension bar attached to the top of the support so as to perform a seesaw motion that reciprocates in the vertical direction at the fulcrum, and the other end located behind the fulcrum of the suspension bar. A provided human body suspension point, a mechanism suspension point provided at one end located in front of the fulcrum of the suspension rod, an elastic expansion / contraction mechanism attached to the apparatus frame connected to the column and the column, and the column A winding mechanism attached to the device frame connected to the support column, a suspension rope having one end connected to the upper part of the elastic telescopic mechanism and the other end connected to the winding mechanism via a human body suspension point And a moving pulley that can be moved up and down by being hung from a hanging rope suspended from a hanging point of the human body, and the moving pulley includes a hook for hanging the human body.
The other end side dimension from the fulcrum of the suspension bar to the human body suspension point of the suspension bar is also longer than the one end side dimension from the fulcrum of the suspension bar to the mechanism suspension point of the suspension bar.
The hanging rod is also provided with a stopper for restricting the upward movement of the other end of the hanging rope.

本発明によれば、動滑車を採用したことにより、巻取機構の回転数が同じである場合に、人体吊下げ点より吊り下げた吊りロープをそのまま上動させる場合に比べて吊りロープを上動させる速さを遅くでき、かつ、動滑車が吊りロープ上を滑走し、動滑車が滑らかに上動する構造としたので、使用者に対する上動時の衝撃を和らげることのできる優しい歩行支援装置が得られる。
シーソーのような吊棒を備え、吊棒の支点から吊棒の人体吊下げ点までの他端側寸法を、吊棒の支点から吊棒の機構吊下げ点までの一端側寸法よりも長くしたので、人体吊下げ点の上下移動可能幅を大きくできるとともに吊上げ装置により人体吊下げ点に付与される吊上力を大きくできる。即ち、人体吊下げ点で吊下げられた使用者の上下移動可能幅を大きくできるとともに使用者の体重負荷を軽減するための吊上力を大きくできる。したがって、使用者の体重負荷を軽減できるとともに使用者の歩行動作に伴う使用者の上下動にも追従できて自然な歩行を支援できる歩行支援装置が得られる。また、機構吊下げ点の上下移動可能幅を人体吊下げ点の上下移動可能幅よりも小さくできるので、人体吊下げ点で吊下げられた使用者の上下移動に伴う吊上力の変動を小さくできる。そして、人体吊下げ点で吊下げられた使用者の上下移動可能幅を大きくしたため、人体吊下げ点に人が吊下げられていない状態において吊棒の他端部が支点より上方に位置される構成の歩行支援装置において、巻取機構を操作して人体吊下げ点の位置を下方に移動できて、車椅子からの移行の容易な歩行支援装置を提供できる。
吊棒が、吊りロープの他端の上方への移動を規制するストッパを備えたので、吊りロープの他端の上方への移動がストッパにより規制された後に使用者に吊上力が付与されるので、使用者が宙吊り状態となるようなことがなく、安全性の高い歩行支援装置を提供できる。
According to the present invention, by adopting the movable pulley, when the number of rotations of the winding mechanism is the same, the suspension rope is lifted as compared with the case where the suspension rope suspended from the human body suspension point is moved up as it is. A gentle walking support device that can slow down the speed of movement, and the moving pulley slides on the hanging rope and the moving pulley moves up smoothly, so that the impact on the user when moving up can be reduced. Is obtained.
With a suspension rod like a seesaw, the other end side dimension from the suspension bar fulcrum to the suspension bar human body suspension point is longer than the one end dimension from the suspension bar fulcrum to the suspension bar mechanism suspension point Therefore, the vertically movable width of the human body suspension point can be increased and the lifting force applied to the human body suspension point by the lifting device can be increased. That is, it is possible to increase the vertically movable width of the user suspended at the human body suspension point and to increase the lifting force for reducing the weight load of the user. Therefore, it is possible to obtain a walking support device that can reduce the user's weight load and can follow the user's vertical movement accompanying the user's walking motion to support natural walking. In addition, since the vertically movable width of the mechanism hanging point can be made smaller than the vertically movable width of the human body hanging point, the fluctuation of the lifting force accompanying the vertical movement of the user suspended at the human body hanging point is reduced. it can. And since the up-and-down movable width of the user suspended at the human body suspension point is increased, the other end of the suspension bar is positioned above the fulcrum in a state where no human is suspended at the human body suspension point. In the walking support apparatus having the configuration, the walking support apparatus can be provided which can move the position of the human body suspension point downward by operating the winding mechanism and can easily shift from the wheelchair.
Since the suspension bar has a stopper that restricts the upward movement of the other end of the suspension rope, a lifting force is applied to the user after the upward movement of the other end of the suspension rope is restricted by the stopper. Therefore, it is possible to provide a highly safe walking support device without the user being suspended.

The structure of the case is disassembled.

図2;図3を参照し、まず、歩行支援装置1の概要を説明する。歩行支援装置1は、支柱2、吊棒3、人体吊下げ点4、弾性伸縮機構5、巻取機構7、機構吊下げ点8、装置フレーム9、走行部10、昇降機構86を備える。   FIG. 2; With reference to FIG. 3, the outline | summary of the walk assistance apparatus 1 is demonstrated first. The walking support device 1 includes a column 2, a suspension rod 3, a human body suspension point 4, an elastic telescopic mechanism 5, a winding mechanism 7, a mechanism suspension point 8, a device frame 9, a traveling unit 10, and a lifting mechanism 86.

支柱2は上下に延長する。装置フレーム9は支柱2に連結される。装置フレーム9は下部に土台フレーム部33を備え、土台フレーム部33に走行部10が設けられる。   The support column 2 extends vertically. The device frame 9 is connected to the support 2. The apparatus frame 9 includes a base frame portion 33 at a lower portion, and the traveling unit 10 is provided on the base frame portion 33.

吊棒3は、支柱2の上部に回転可能に取付けられることによって、回転中心軸13を支点14として一端部12と他端部15とが互いに上下方向に往復するシーソー運動を行う。   The suspension bar 3 is rotatably attached to the upper part of the support 2 to perform a seesaw motion in which the one end portion 12 and the other end portion 15 reciprocate in the vertical direction with the rotation center shaft 13 as a fulcrum 14.

人体吊下げ点4は、吊棒3の支点14よりも後側に位置する吊棒3の他端部15に設けられる。
機構吊下げ点8は、吊棒3の支点14より前側に位置する吊棒3の一端部12に設けられる。
The human body suspension point 4 is provided at the other end portion 15 of the suspension rod 3 located behind the fulcrum 14 of the suspension rod 3.
The mechanism suspension point 8 is provided at one end portion 12 of the suspension bar 3 positioned in front of the fulcrum 14 of the suspension bar 3.

吊棒3の支点14から吊棒3の人体吊下げ点4までの他端側寸法aは、吊棒3の支点14から吊棒3の機構吊下げ点8までの一端側寸法bよりも長い。   The other end side dimension a from the fulcrum 14 of the suspension bar 3 to the human body suspension point 4 of the suspension bar 3 is longer than the one end side dimension b from the fulcrum 14 of the suspension bar 3 to the mechanism suspension point 8 of the suspension bar 3. .

弾性伸縮機構5を説明する。弾性伸縮機構5は、図2に示すように、弾性体としてのコイルばね51、収納ケース52を備える。図3に示すように、収納ケース52は、上端開口下端閉塞の大径筒体53、下端開口上端閉塞の小径筒体54、締結キャップ55を備える。大径筒体53の筒の内径dは小径筒体54の筒の外径よりも大きい。大径筒体53の筒壁には溝58が形成される。溝58は筒壁の内周面56から外周面57に貫通するとともに上端開口59から下端60に向けて一直線状に延長する。外周面57における溝58の横には溝58の上下方向に渡って吊上力の目盛部61が設けられる。小径筒体54の筒の外周面62の下部には外周面62より外側に突出する指針軸63が設けられる。小径筒体54が大径筒体53の筒内に収納された場合に、指針軸63が溝58を経由して溝58よりも大径筒体53の外周面57の外側に突出して溝58内を上下に移動可能である。指針軸63が目盛部61のある目盛値の横に位置された場合に、その目盛値が吊上力を示すように目盛部61が形成される。大径筒体53の上端開口59側の外周面57にはねじ部64が形成される。締結キャップ55の筒の内壁にはねじ部64にねじ嵌合するねじ部64a(図2参照)が形成される。図2に示すように、弾性伸縮機構5は、大径筒体53の筒の底面に設けられた係留部65にコイルばね51の一端66が連結され、小径筒体54の筒の底面に設けられた係留部67にコイルばね51の他端68が連結され、小径筒体54の下端開口側の筒部が大径筒体53の上端開口59側の筒の内側に嵌め込まれるとともに指針軸63が溝58内に嵌め込まれ、締結キャップ55が小径筒体54の上端閉塞側から小径筒体54の外周面62に挿入されて大径筒体53のねじ部64に締結される。コイルばね51の両端の引掛部を係留部65及び係留部67などに引っ掛けることでコイルばね51を小径筒体54と大径筒体53とに連結できる。そして、吊りロープ16の一端部16aが弾性伸縮機構5の上端部に形成された連結部22に連結され、弾性伸縮機構5の下端部24と装置フレーム部9とが互い連結される。吊りロープ16の他端16bは、後述する巻取枠92に連結され、後述する巻取機構7の操作ハンドル94を操作して吊りロープ16を巻き取る方向に巻取枠92を回転させることで、コイルばね51が上下方向に伸びる。この際の、コイルばね51が元の状態に戻ろうとする力(コイルばね51が縮もうとする力)が吊上力となり、その吊上力の値はそのときの指針軸63の横の目盛値で示される。つまり、巻取機構7を操作して、巻取枠92に吊りロープ16を巻き取れば吊上力を大きくでき、巻取枠92から吊りロープ16を巻き出せば吊上力を小さくできる。すなわち、装着具18を装着した使用者19の体を吊り上げる吊上力(体重免荷量)が巻取機構7による吊りロープ16の巻取量によって決定される歩行支援装置1となり、吊上力を変更するための操作を容易とできて、吊上力を容易に変更可能な歩行支援装置1が得られる。   The elastic expansion / contraction mechanism 5 will be described. As shown in FIG. 2, the elastic expansion / contraction mechanism 5 includes a coil spring 51 and a storage case 52 as elastic bodies. As shown in FIG. 3, the storage case 52 includes a large-diameter cylinder 53 that is closed at the lower end of the upper end opening, a small-diameter cylinder 54 that is closed at the upper end of the lower end opening, and a fastening cap 55. The inner diameter d of the large diameter cylinder 53 is larger than the outer diameter of the small diameter cylinder 54. A groove 58 is formed in the cylindrical wall of the large-diameter cylindrical body 53. The groove 58 extends from the inner peripheral surface 56 to the outer peripheral surface 57 of the cylindrical wall and extends in a straight line from the upper end opening 59 toward the lower end 60. A scale 61 for lifting force is provided on the outer peripheral surface 57 next to the groove 58 in the vertical direction of the groove 58. A pointer shaft 63 that protrudes outward from the outer peripheral surface 62 is provided below the outer peripheral surface 62 of the cylinder of the small-diameter cylindrical body 54. When the small-diameter cylindrical body 54 is accommodated in the cylinder of the large-diameter cylindrical body 53, the pointer shaft 63 protrudes to the outside of the outer peripheral surface 57 of the large-diameter cylindrical body 53 from the groove 58 via the groove 58. It can move up and down. When the pointer shaft 63 is positioned beside a certain scale value of the scale portion 61, the scale portion 61 is formed such that the scale value indicates the lifting force. A threaded portion 64 is formed on the outer peripheral surface 57 of the large-diameter cylindrical body 53 on the upper end opening 59 side. A threaded portion 64 a (see FIG. 2) that is screwed into the threaded portion 64 is formed on the inner wall of the cylinder of the fastening cap 55. As shown in FIG. 2, the elastic expansion / contraction mechanism 5 is provided on the bottom surface of the cylinder of the small-diameter cylindrical body 54 by connecting one end 66 of the coil spring 51 to the anchoring portion 65 provided on the bottom surface of the cylinder of the large-diameter cylindrical body 53. The other end 68 of the coil spring 51 is connected to the moored portion 67 so that the cylinder portion on the lower end opening side of the small diameter cylindrical body 54 is fitted inside the cylinder on the upper end opening 59 side of the large diameter cylindrical body 53 and the pointer shaft 63. Is inserted into the groove 58, and the fastening cap 55 is inserted into the outer peripheral surface 62 of the small diameter cylindrical body 54 from the upper end closing side of the small diameter cylindrical body 54 and fastened to the screw portion 64 of the large diameter cylindrical body 53. The coil spring 51 can be connected to the small-diameter cylindrical body 54 and the large-diameter cylindrical body 53 by hooking hooks at both ends of the coil spring 51 to the anchoring portion 65 and the anchoring portion 67. And the one end part 16a of the suspension rope 16 is connected with the connection part 22 formed in the upper end part of the elastic expansion-contraction mechanism 5, and the lower end part 24 and the apparatus frame part 9 of the elastic expansion-contraction mechanism 5 are mutually connected. The other end 16b of the suspension rope 16 is connected to a winding frame 92 described later, and an operation handle 94 of the winding mechanism 7 described later is operated to rotate the winding frame 92 in a direction in which the suspension rope 16 is wound. The coil spring 51 extends in the vertical direction. At this time, the force that the coil spring 51 tries to return to the original state (the force that the coil spring 51 tries to contract) becomes the lifting force, and the value of the lifting force is the scale on the side of the pointer shaft 63 at that time. Indicated by value. That is, by operating the winding mechanism 7 and winding the suspension rope 16 around the winding frame 92, the lifting force can be increased, and by lifting the suspension rope 16 from the winding frame 92, the lifting force can be decreased. That is, the lifting force (weight unloading amount) that lifts the body of the user 19 wearing the wearing tool 18 is determined by the winding amount of the hanging rope 16 by the winding mechanism 7, and the lifting force 1 The walking assist device 1 can be obtained which can easily change the lifting force and can easily change the lifting force.

The moving pulley 87 includes a moving pulley 151, front and rear support pulleys 152; 153, and a moving pulley stopper 154. The guide pulley unit 88 includes guide pulleys 155 and 156 provided on the connecting rod 83 and guide pulleys 157 and 158 and 159 provided on the rotation center shaft 13. The elastic expansion / contraction mechanism 5 has a lower end portion 24 attached to the right end portion of the front frame portion 37 of the base frame portion 35 by welding, bolts and nuts or the like. One end 16a of the suspension rope 16 is connected to a connection portion 22 formed at the upper end of the elastic telescopic mechanism 5, and the other end 16b of the suspension rope 16 is a guide pulley 155, a right guide pulley 157, and a right movable pulley portion.

Note that the length of the hanging rope 16 is determined so that the hooking tool 200 provided on the movable pulley 151 is lowered to a position about the height of the seat plate of the wheelchair when completely unwound from the winding frame 92. It is done.

昇降機構86による昇降動作を説明する。動滑車151の滑車保持ケース159aが動滑車ストッパ154に衝突して、動滑車ストッパ154が動滑車151の上方への移動を規制している状態から動滑車151を下方に移動する場合、介護者などが、操作ハンドル94を回転させることによって、車椅子に乗った人の腰の位置まで、動滑車151を下方に移動する。出入部38を経由して左支柱31と右支柱32との間に入り込んだ車椅子に乗った使用者19が装着した装着具18の吊下ロープ201(図2参照)の上端に設けられた図外の引掛具を動滑車151の引掛具200に引っ掛ける。そして、介護者などが、操作ハンドル94を操作して、動滑車151を上方に移動する。動滑車151の上方への移動が動滑車ストッパ154により規制された後も操作ハンドル94を操作して巻取枠92を巻取方向に回転させ続けると、吊りロープ16が巻取枠92で巻き取られ続けることによって弾性伸縮機構5のコイルばね51が伸びて人体吊下げ点4に吊上力が付与される。弾性伸縮機構5の目盛を見て所望の吊上力に設定すれば、使用者は所望の吊上力で吊上げられ、体重負荷が軽減された状態での歩行が可能となる。   The raising / lowering operation by the raising / lowering mechanism 86 is demonstrated. When the pulley holding case 159a of the moving pulley 151 collides with the moving pulley stopper 154 and the moving pulley stopper 154 moves the moving pulley 151 downward from the state where the moving pulley 151 is restricted from moving upward, the caregiver For example, by rotating the operation handle 94, the movable pulley 151 is moved downward to the position of the waist of the person on the wheelchair. The figure provided in the upper end of the suspension rope 201 (refer FIG. 2) of the mounting tool 18 with which the user 19 who got on the wheelchair who entered between the left support | pillar 31 and the right support | pillar 32 via the entrance / exit part 38 was equipped. The outer hooking tool is hooked on the hooking tool 200 of the movable pulley 151. Then, a caregiver or the like operates the operation handle 94 to move the movable pulley 151 upward. Even after the upward movement of the movable pulley 151 is restricted by the movable pulley stopper 154, if the operating handle 94 is operated and the winding frame 92 is continuously rotated in the winding direction, the suspension rope 16 is wound around the winding frame 92. By continuing to be taken, the coil spring 51 of the elastic expansion / contraction mechanism 5 is extended, and a lifting force is applied to the human body suspension point 4. If the desired lifting force is set by looking at the scale of the elastic telescopic mechanism 5, the user can be lifted with the desired lifting force and can walk with a reduced weight load.

尚、図1の構成の場合、人体吊下げ点4は、前後の支持滑車152;153のロープ吊下げ点により形成され、機構吊下げ点8は、吊りロープ16の一端部16aに最も近い側を案内する案内滑車155のロープ吊下げ点により形成される。すなわち、一端部16aが弾性伸縮機構5の上部に連結され他端部16bが人体吊下げ点4を経由して巻取機構7に連結された吊りロープ16と、人体吊下げ点4を形成する前後の支持滑車152;153より吊り下げられた吊りロープ16に掛け渡されて上下動可能となった動滑車151とを備え、動滑車151が使用者19を吊るための引掛具200を備える。   1, the human body suspension point 4 is formed by the rope suspension points of the front and rear support pulleys 152; 153, and the mechanism suspension point 8 is the side closest to the one end 16a of the suspension rope 16. It is formed by the rope suspension point of the guide pulley 155 that guides. That is, a suspension rope 16 in which one end portion 16a is coupled to the upper portion of the elastic telescopic mechanism 5 and the other end portion 16b is coupled to the winding mechanism 7 via the human body suspension point 4 and the human body suspension point 4 are formed. The movable pulley 151 is provided on a suspension rope 16 suspended from the front and rear support pulleys 152 and 153 and can move up and down. The movable pulley 151 includes a hook 200 for hanging the user 19.

最良の形態では、吊棒3の支点14から吊棒3の人体吊下げ点4までの他端側寸法aを、吊棒3の支点14から吊棒3の機構吊下げ点8までの一端側寸法bよりも長くしたので、人体吊下げ点4で吊下げられた使用者19の上下移動可能幅を大きくできる。つまり、人体吊下げ点4の上下移動可能幅=機構吊下げ点8の上下移動可能幅×(a/b)となる。したがって、使用者19の歩行動作に伴う使用者19の上下動に追従できるようになるとともに使用者19の体重負荷を軽減するための吊上力を大きくできる。よって、自力で体重を支えきれない使用者19であっても自然な歩行を行えるように歩行支援できる歩行支援装置1が得られる。   In the best mode, the other end side dimension a from the fulcrum 14 of the suspension rod 3 to the human body suspension point 4 of the suspension rod 3 is the one end side from the fulcrum 14 of the suspension rod 3 to the mechanism suspension point 8 of the suspension rod 3. Since the length is longer than the dimension b, the up and down movable width of the user 19 suspended at the human body suspension point 4 can be increased. That is, the vertically movable width of the human body hanging point 4 = the vertically movable width of the mechanism hanging point 8 × (a / b). Therefore, it becomes possible to follow the vertical movement of the user 19 accompanying the walking motion of the user 19 and increase the lifting force for reducing the weight load of the user 19. Therefore, the walking support device 1 that can support walking so that even the user 19 who cannot support his / her weight by himself / herself can walk naturally can be obtained.

また、人体吊下げ点4に吊上力が作用している状態から使用者19の歩行動作に伴って人体吊下げ点4の位置が上下に移動した場合には吊上力が変動するが、他端側寸法aを一端側寸法bよりも長くしたので、機構吊下げ点8の上下移動可能幅を人体吊下げ点4の上下移動可能幅よりも小さくでき、人体吊下げ点4で吊下げられた使用者19の上下移動に伴う吊上力の変動を小さくできる。   Moreover, when the position of the human body hanging point 4 moves up and down with the walking motion of the user 19 from the state where the lifting force is acting on the human body hanging point 4, the lifting force varies. Since the other end side dimension “a” is longer than the one end side dimension “b”, the vertically movable width of the mechanism suspension point 8 can be made smaller than the vertically movable width of the human body suspension point 4 and is suspended at the human body suspension point 4. The fluctuation of the lifting force accompanying the vertical movement of the user 19 can be reduced.

例えば、他端側寸法aと一端側寸法bとの比を7:1とした場合、人体吊り下げ点4に25kgの吊上力を作用させるためには、機構吊り下げ点8を175kgの力で下方に引っ張る必要がある。そして、人体吊り下げ点4に25kgの吊上力が作用している状態から使用者の歩行動作に伴って人体吊り下げ点4の位置を上下に10.5cmずつ移動可能なようにする(即ち、人体吊り下げ点4の上下移動可能幅を21cmにする)ためには、コイルばね51の伸縮によって機構吊り下げ点8が上下に1.5cmずつ移動可能としなければならない(即ち、機構吊り下げ点8の上下移動可能幅を3cmにする)。よって、この場合、機構吊り下げ点8に175kgの力を付与でき、かつ、機構吊り下げ点8を上下に1.5cmずつ移動可能とできるコイルばね51を使用すればよい。すなわち、コイルばね51は、設定したい、最大吊上力、人体吊り下げ点4の位置の上下最大移動可能幅に応じて、その設定値を実現できるものを選定すればよい。この場合、人体吊下げ点4で吊下げられた使用者19の上下移動可能幅を21cmと大きくでき、しかも、使用者19の体重負荷を軽減するための吊上力を25kg程度と大きくできる。したがって、人体吊下げ点4が使用者19の歩行動作に伴う使用者19の上下動に追従できるようになり、使用者19の体重負荷を軽減するための吊上力も大きいので、自力で体重を支えきれない使用者19であっても自然な歩行を行えるように歩行支援できる歩行支援装置1が得られる。また、人体吊り下げ点4の上下移動可能幅21cmに対して機構吊り下げ点8の上下移動可能幅を3cmにでき、機構吊下げ点8の上下移動可能幅を人体吊下げ点4の上下移動可能幅よりも小さくできるので、人体吊下げ点4で吊下げられた使用者19の上下移動に伴う吊上力の変動を小さくできる。   For example, when the ratio of the other end side dimension a to the one end side dimension b is 7: 1, in order to apply a lifting force of 25 kg to the human body hanging point 4, the mechanism hanging point 8 is set to a force of 175 kg. It is necessary to pull it down. Then, the position of the human body suspension point 4 can be moved up and down by 10.5 cm in accordance with the user's walking movement from the state in which a lifting force of 25 kg is applied to the human body suspension point 4 (that is, In order to make the vertically movable width of the human body hanging point 4 21 cm), the mechanism hanging point 8 must be movable up and down by 1.5 cm by extending and contracting the coil spring 51 (that is, the mechanism hanging). The vertical movable width of point 8 is 3 cm). Therefore, in this case, a coil spring 51 that can apply a force of 175 kg to the mechanism suspension point 8 and can move the mechanism suspension point 8 up and down by 1.5 cm may be used. That is, the coil spring 51 may be selected according to the maximum lifting force that is desired to be set and the maximum vertically movable width of the position of the human body suspension point 4. In this case, the vertically movable width of the user 19 suspended at the human body suspension point 4 can be increased to 21 cm, and the lifting force for reducing the weight load on the user 19 can be increased to about 25 kg. Therefore, the human body hanging point 4 can follow the vertical movement of the user 19 accompanying the walking movement of the user 19, and the lifting force for reducing the weight load of the user 19 is also large. Even if it is the user 19 who cannot support, the walk assistance apparatus 1 which can assist walk so that natural walk can be performed is obtained. Further, the vertically movable width of the mechanism hanging point 8 can be 3 cm with respect to the vertically movable width 21 cm of the human body hanging point 4, and the vertically movable width of the mechanism hanging point 8 can be vertically moved by the human body hanging point 4. Since it can be made smaller than the possible width, it is possible to reduce the fluctuation of the lifting force accompanying the vertical movement of the user 19 suspended at the human body suspension point 4.

他端側寸法aと一端側寸法bとを同じにした場合や他端側寸法aを一端側寸法bよりも短くした場合と、他端側寸法aを一端側寸法bよりも長くした場合とを比較すると、他端側寸法aを一端側寸法bよりも長くした場合の方が、人体吊下げ点4で吊下げられた使用者19の上下移動可能幅を大きくできるとともに使用者19の体重負荷を軽減するための吊上力を大きくでき、しかも、使用者19の上下移動に伴う吊上力の変動を小さくできる。   When the other end side dimension a and the one end side dimension b are the same, when the other end side dimension a is made shorter than the one end side dimension b, and when the other end side dimension a is made longer than the one end side dimension b When the other end side dimension “a” is longer than the one end side dimension “b”, the user 19 suspended at the human body suspension point 4 can have a larger vertical movable width and the weight of the user 19 can be increased. The lifting force for reducing the load can be increased, and the fluctuation of the lifting force accompanying the vertical movement of the user 19 can be reduced.

さらに最良の形態によれば、人体吊下げ点4で吊下げられた使用者19の上下移動可能幅を大きくできるとともに使用者19の体重負荷を軽減するための吊上力を大きくでき、しかも、使用者19の上下移動に伴う吊上力の変動を小さくできる歩行支援装置1において、昇降機構86を備えたことによって、車椅子に乗った人を、車椅子に乗った状態から吊上げることができ、車椅子に乗った人でも使用可能な歩行支援装置1が得られる。   Furthermore, according to the best mode, the up and down movable width of the user 19 suspended at the human body suspension point 4 can be increased and the lifting force for reducing the weight load of the user 19 can be increased, In the walking support device 1 that can reduce the fluctuation of the lifting force accompanying the vertical movement of the user 19, by providing the lifting mechanism 86, a person on the wheelchair can be lifted from the state on the wheelchair, A walking support device 1 that can be used even by a person on a wheelchair is obtained.

また、動滑車151による昇降構成としたため、巻取機構7の回転数が同じである場合に、人体吊下げ点4より吊り下げた吊りロープ6をそのまま上動させる場合に比べて吊りロープ6を上動させる速さを遅くできる。また、動滑車151が吊りロープ6上を滑走し、動滑車151が滑らかに上動する構造としたので、引掛具200の昇降動作が緩やかとなり、使用者19に対する上動時の衝撃を和らげることのできる優しい歩行支援装置1が得られる。また、動滑車151の上方への移動が動滑車ストッパ154により規制された後に使用者19に吊上力が付与されるので、使用者19が宙吊り状態となるようなことがなく、安全性が高い。   Moreover, since it was made into the raising / lowering structure by the dynamic pulley 151, when the rotation speed of the winding mechanism 7 is the same, compared with the case where the suspension rope 6 suspended from the human body suspension point 4 is moved up as it is, the suspension rope 6 is made. The speed to move up can be slowed down. In addition, since the movable pulley 151 slides on the suspension rope 6 and the movable pulley 151 moves up smoothly, the lifting and lowering operation of the hooking tool 200 becomes gentle, and the impact on the user 19 during the upward movement can be reduced. A gentle walking support device 1 that can be used is obtained. Further, since the lifting force is applied to the user 19 after the upward movement of the moving pulley 151 is restricted by the moving pulley stopper 154, the user 19 is not suspended from the air, and safety is ensured. high.

また、最良の形態では、吊棒3の他端側寸法aを一端側寸法bよりも長くして、人体吊下げ点4で吊下げられた使用者19の上下移動可能幅を大きくしたため、人体吊下げ点4に人が吊下げられていない状態において吊棒3の他端部15は支点14より上方に位置される。このような構成の歩行支援装置1において、昇降機構86により引掛具200の位置を下方に移動できるようにしたことにより、装着具18の引掛具を引掛具200に引っ掛ける作業が容易となるという意義がある。すなわち、巻取機構7を操作して人体吊下げ点4の位置を下方に移動できるようにしたことにより、車椅子からの移行の容易な歩行支援装置1を提供できる。また、背の低い人でも装着具18の引掛具を引掛具200に引っ掛けることができるようになるという意義がある。   Further, in the best mode, the other end side dimension a of the suspension bar 3 is made longer than the one end side dimension b, so that the vertically movable width of the user 19 suspended at the human body suspension point 4 is increased. In a state where no person is suspended from the hanging point 4, the other end 15 of the hanging rod 3 is positioned above the fulcrum 14. In the walking support device 1 having such a configuration, the position of the hooking tool 200 can be moved downward by the elevating mechanism 86, so that the work of hooking the hooking tool of the mounting tool 18 on the hooking tool 200 becomes easy. There is. That is, by operating the winding mechanism 7 so that the position of the human body suspension point 4 can be moved downward, it is possible to provide the walking support device 1 that can be easily shifted from the wheelchair. Further, there is a significance that even a short person can hook the hooking tool 18 on the hooking tool 200.

また、最良の形態の歩行支援装置1によれば、巻取機構7を備え、吊上力を巻取機構7による吊りロープ16の巻取量で決定される構成としたため、巻取機構7を操作して吊りロープ16を巻き取ったり、巻き出したりすることによって、吊上力を容易に変更でき、吊上力を変更するための操作の容易な歩行支援装置1が得られる。
また、弾性伸縮機構5の弾性体としてコイルばね51を用いたので、弾性伸縮機構5の構成を簡単にでき、吊上力を容易に変更可能な構成の歩行支援装置1を安価に得ることができる。
また、巻取機構7として手巻式ウインチ装置を用いたことによって、吊上力の変更操作を容易とできる。
また、使用者が図2のように弾性伸縮機構の設けられた前側を向いて使用することで、重量のある前側を押すような感じとなるため、歩行支援装置1を前方に移動させやすくなる。
また、使用者19が弾性伸縮機構5の設けられた前側を向いて使用する場合、弾性伸縮機構5が前方の中央にあると使用者19の前方視界が妨げられるので、弾性伸縮機構5を、図1に示すように、前側の右端側(あるいは左端側)に寄せて設けたことで、前方視界を妨げない装置が得られる。
Moreover, according to the walking assistance apparatus 1 of the best form, since the winding mechanism 7 is provided and the lifting force is determined by the winding amount of the suspension rope 16 by the winding mechanism 7, the winding mechanism 7 is By operating and winding the suspension rope 16 or unwinding, the lifting force can be easily changed, and the walking assist device 1 that is easy to operate for changing the lifting force can be obtained.
In addition, since the coil spring 51 is used as the elastic body of the elastic expansion / contraction mechanism 5, the configuration of the elastic expansion / contraction mechanism 5 can be simplified, and the walking support device 1 having a configuration that can easily change the lifting force can be obtained at low cost. it can.
Further, by using a hand-winding winch device as the winding mechanism 7, it is possible to easily change the lifting force.
Moreover, since the user feels as if he / she pushes the heavy front side by using the front side where the elastic expansion / contraction mechanism is provided as shown in FIG. 2, the walking support device 1 can be easily moved forward. .
In addition, when the user 19 is used facing the front side where the elastic expansion / contraction mechanism 5 is provided, if the elastic expansion / contraction mechanism 5 is in the center of the front, the user 19's front field of view is hindered. As shown in FIG. 1, a device that does not obstruct the front field of view can be obtained by being provided close to the front right end (or left end).

尚、特許文献1の歩行支援装置では、例えば使用者が、体重が軽く背も低く非力な子供のような場合、スプリングのばね力によっては電動ウインチでロープを巻き上げていくと使用者が吊り上げられてしまう可能性があり、危険である。本発明では、このような現象を防ぐために、動滑車151の一定以上の上方への移動を規制する動滑車ストッパ154を設け、使用者19が一定高さ以上吊り上げられられない状態において吊上力を加えるようにしているので、安全である。   In addition, in the walking support device of Patent Document 1, for example, when the user is a child who is light, short, and weak, depending on the spring force of the spring, the user can be lifted by winding the rope with an electric winch. This is dangerous. In the present invention, in order to prevent such a phenomenon, a moving pulley stopper 154 for restricting the upward movement of the moving pulley 151 beyond a certain level is provided, and the lifting force in a state where the user 19 cannot be lifted above a certain height. It is safe because it adds.

コイルばねの上下端に板を備え、上端の板を針金で大径筒体53の内底に連結し、下端の板を針金で小径筒体54の内底に連結し、調整ロープ6を巻き取って上下の板間のコイルばねを縮ませることによって、コイルばねが元の状態に戻ろうとする力(コイルばねが伸びようとする力)を吊上力とする構成の弾性伸縮機構5を用いてもよい。この場合、コイルばねが縮みきった状態が転倒防止ストッパとして機能するので、支柱2の上部に転倒防止ストッパ29を設ける必要がなくなる。弾性伸縮機構5の弾性体としてゴムを用いてもよい。流体による弾性機能を用いた弾性伸縮機構5を用いてもよい。他端側寸法aと一端側寸法bとを同じにしてもよい。この場合でも、動滑車151を採用したことにより、ロープの引き回しが簡単となり、また、吊棒3に沿ってロープを引き回すことが可能となるので、ロープが案内滑車から外れにくい構造とできる。   A plate is provided at the upper and lower ends of the coil spring, the upper end plate is connected to the inner bottom of the large diameter cylindrical body 53 with a wire, the lower end plate is connected to the inner bottom of the small diameter cylindrical body 54 with a wire, and the adjustment rope 6 is wound. By using the elastic expansion and contraction mechanism 5 having a structure in which the force that the coil spring tries to return to the original state (the force that the coil spring tries to extend) is the lifting force by contracting the coil spring between the upper and lower plates. May be. In this case, since the state in which the coil spring is fully contracted functions as a fall prevention stopper, it is not necessary to provide the fall prevention stopper 29 on the upper portion of the column 2. Rubber may be used as the elastic body of the elastic expansion / contraction mechanism 5. You may use the elastic expansion-contraction mechanism 5 using the elastic function by a fluid. The other end side dimension a and the one end side dimension b may be the same. Even in this case, the use of the movable pulley 151 makes it easy to route the rope, and the rope can be routed along the suspension rod 3, so that the rope is less likely to come off the guide pulley.
