Description

本発明は、足が不自由な方や高齢者など、歩行を補助する器具(例:杖)を必要とする方が、段差や階段の上り下りや、椅子からの起立を助ける段差昇降補助機能及び起立補助機能付き歩行補助具に関する。   The present invention is a step elevation assist function that assists walking and climbing up and down steps and standing up from a chair, such as people with disabilities and elderly people who require walking aids (eg walking sticks). The present invention also relates to a walking aid with a standing assistance function.

従来、歩行補助具として、棒状の杖主体の上端に握り部と、前記杖主体の下端に、横に張り出したステップ台付きの石突きとで構成されているものが知られている。当該歩行補助具によって、歩行者は、階段や段差を昇降する際、一度、歩行補助具のステップ台に片足を乗せてから、段差一段分、体を上下させた後、他方の足を次の段へかけることで、体への負担を減らしながら、昇降が可能となる。
このステップ台は、棒状の杖主体に横に張り出した状態で固定されたもの(特許文献1)、電動モータによる上下動が可能なもの(特許文献2)、棒状の杖主体に収納可能に接続されているもの(特許文献3)などがある。
2. Description of the Related Art Conventionally, walking aids are known which are composed of a grip portion at the upper end of a stick-shaped cane main body and a stone thruster with a step base extending laterally at the lower end of the cane main body. With this walking aid, when a pedestrian goes up and down stairs or steps, he puts one foot on the step base of the walking aid and then raises and lowers the body by one step, then the other foot By stepping, it is possible to move up and down while reducing the burden on the body.
This step base is fixed to the rod-shaped cane main body in a state of extending sideways (Patent Document 1), can be moved up and down by an electric motor (Patent Document 2), and can be stored in the rod-shaped cane main body so that it can be stored. (Patent Document 3) and the like.

しかしながら、従来の歩行補助具は、階段や段差等を昇降しない時、すなわち、平坦部を歩行する時も、足載せ用のステップ台を石突き部に装着しながら、使用しなければならず、足を踏み出す位置とステップ台とが重なり、使用者が転倒してしまうリスクがある。例え、収納可能であったとしても、足を載せるステップ台という重量物が下端に接続された歩行補助具を、常に上げ下げしながら歩行しなければならないのは、高齢者に取って負荷が大きい。電動モータ等の器具が付いた歩行補助具であれば、更にその重量が増すことが想定される。
更に、従来の歩行補助具には、階段や段差の昇降を補助する機能しかなく、高齢者が腰掛けた状態から起立する際の補助機能など、付加機能は付いていない。
However, conventional walking aids must be used while not stepping up and down stairs, steps, etc., that is, when walking on a flat part, while mounting a step table for footrest on the stone thrusting part, There is a risk that the position where the foot is stepped on and the step base overlap and the user falls. For example, even if it can be stowed, it is a heavy burden for elderly people to walk while always lifting and lowering a walking aid having a heavy weight called a step base on which a foot is placed. In the case of a walking aid equipped with an appliance such as an electric motor, it is assumed that the weight further increases.
Furthermore, the conventional walking aid has only a function of assisting the raising and lowering of stairs and steps, and has no additional functions such as an assisting function when an elderly person stands up.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Example 1
FIG. 1 is an exploded view of a walking aid according to an embodiment of the present invention. The walking aid of the present invention includes a grip portion 1, a locking ring 2, a first rod-shaped portion 3, a sliding tubular fixing member 4, a spring 5 comprising a coil spring, a stopper 6, a second rod-shaped portion 7, a stone thrust 8, It consists of a belt-shaped elastic rubber 9. Two grips 11 are connected to the grip 1. One end of each handle is connected to the connection ports 12-1 and 12-2 of the trigeminal joint 12, and is fixed to the trigeminal joint with a set screw. Further, the connection port 12-3 at the other end of the three-pronged joint is connected to one end of the first rod-shaped portion 3, and is fixed to the first rod-shaped portion 3 with a screw. In the present embodiment, the end face of the connection port 12-3 of the three-pronged joint also serves as a stopper when sliding to the grip portion side of the fixing member 4 as will be described later. Similarly, a separate stopper may be provided so that the slide end position of the fixed member toward the grip portion can be regulated.

係止リング2は中空であり、管状の固定部材4の内周面に嵌合できる外径を有し、中央の穴に第一棒状部3と帯状の伸縮性ゴム9の一端とを嵌め込み、第一棒状部3の所定位置で締めこまれ、第一棒状部3と帯状の伸縮性ゴム9の一端とが固定されると共に、その下端面でスプリング5の一端部を係止する。スプリング5は、第一棒状部3の外側を覆うように嵌合し、その一端が係止リング2に突き当たるまで挿入される。このとき、第一棒状部3の他端、すなわち、握り部1が装着された一端と反対側の他端部は、スプリング5からはみ出さないように、スプリング5の位置は調整される。第一棒状部3の他端部は、スプリング5の長さ方向中央付近に位置するのが好ましい。スプリング5と第一棒状部3とは、所定間隔で打ち付けられた複数のまた釘によって固定される。   The locking ring 2 is hollow, has an outer diameter that can be fitted to the inner peripheral surface of the tubular fixing member 4, and the first rod-like portion 3 and one end of the belt-like elastic rubber 9 are fitted into the center hole, The first rod-shaped portion 3 is fastened at a predetermined position, and the first rod-shaped portion 3 and one end of the belt-shaped elastic rubber 9 are fixed, and one end portion of the spring 5 is locked at the lower end surface thereof. The spring 5 is fitted so as to cover the outside of the first rod-shaped portion 3 and is inserted until one end of the spring 5 hits the locking ring 2. At this time, the position of the spring 5 is adjusted so that the other end of the first rod-shaped portion 3, that is, the other end opposite to the end where the grip portion 1 is mounted does not protrude from the spring 5. The other end portion of the first rod-like portion 3 is preferably located near the center in the length direction of the spring 5. The spring 5 and the first rod-like portion 3 are fixed by a plurality of nails driven at a predetermined interval.

次に、スプリング5の長さ方向で、第一棒状部3とは反対側から、第二棒状部7がスプリング5に挿入される。第二棒状部7とスプリング5とは、所定間隔で打ち付けられた複数のまた釘によって固定される。このとき、第一棒状部3と第二棒状部7は、それぞれスプリング5と複数のまた釘で固定されているが、両者は単に接触しているだけであり、直接は固定されない。つまり、例えば第一棒状部3を固定して、第二棒状部7のスプリング5と固定されていない端部に力を加えると、スプリング5を介して屈曲する。このとき、スプリングの反作用として、第一棒状部3と第二棒状部7とが一直線になるように反作用力が発生する。   Next, the second rod-like portion 7 is inserted into the spring 5 from the side opposite to the first rod-like portion 3 in the length direction of the spring 5. The second rod-like portion 7 and the spring 5 are fixed by a plurality of nails struck at a predetermined interval. At this time, the first rod-like portion 3 and the second rod-like portion 7 are fixed by the spring 5 and a plurality of nails, respectively, but they are merely in contact with each other and are not fixed directly. That is, for example, when the first rod-shaped portion 3 is fixed and a force is applied to the end of the second rod-shaped portion 7 that is not fixed to the spring 5, the first rod-shaped portion 3 is bent via the spring 5. At this time, as a reaction of the spring, a reaction force is generated so that the first rod-shaped portion 3 and the second rod-shaped portion 7 are in a straight line.

ストッパ6は、スプリング5と第二棒状部7とが接続されていない第二棒状部7の一端部から挿入され、第二棒状部7と帯状の伸縮性ゴム9とを外周側から締め付け固定する。ストッパ6は、帯状の伸縮性ゴム9に長さ方向の力が加わらない位置で第二棒状部の所定位置に固定される。帯状の伸縮性ゴム9は、使用者が取っ手を握った際、進行方向側に、歩行補助具の長さ方向に沿って係止リング2とストッパ6とで締め付け固定される。   The stopper 6 is inserted from one end of the second rod-like portion 7 where the spring 5 and the second rod-like portion 7 are not connected, and the second rod-like portion 7 and the belt-like stretchable rubber 9 are fastened and fixed from the outer peripheral side. . The stopper 6 is fixed to a predetermined position of the second rod-like portion at a position where no force in the length direction is applied to the belt-like stretchable rubber 9. When the user grips the handle, the belt-like stretchable rubber 9 is fastened and fixed by the locking ring 2 and the stopper 6 along the length direction of the walking aid on the traveling direction side.

石突き8は、球形で弾力があるゴム部材からなり、第二棒状部7の端部に適宜手段で接続固定される。石突き8は、本発明の歩行補助具が様々な角度で設置面に突き当てられても、設置面と石突き8との間に摩擦力が生じるように球形状になっているのが望ましい。   The stone bump 8 is formed of a spherical and elastic rubber member, and is connected and fixed to the end of the second rod-shaped portion 7 by appropriate means. It is desirable that the stone bump 8 has a spherical shape so that a frictional force is generated between the installation surface and the stone bump 8 even when the walking aid of the present invention is abutted against the installation surface at various angles. .

スライド式の固定部材4は、中空で筒状の硬質プラスチック管や金属管等の軽量剛性材からなり、スプリング5の外周と、隙間ができない程度の内径である。スライド式の固定部材4は、第一棒状部3、第二棒状部7、係止リング2、スプリング5、帯状の伸縮性ゴム9の外側から覆うように、三又ジョイントの接続口12−3とストッパ6との間で、歩行補助具の長さ方向にスライド自在に嵌合される。ただし、ストッパに突き当たると、それ以上、スライドしないようになっている。なお、本実施例では、前述したように握り部の接続口12−3で第一棒状部のストッパを兼用しているが、係止リング2に代えてストッパ6と同様なストッパを設けて、該ストッパに伸縮性ゴムの一端部を固定すると共に、固定部材のスライド位置を規制するようにしてもよい。   The slide-type fixing member 4 is made of a lightweight rigid material such as a hollow, cylindrical hard plastic tube or metal tube, and has an inner diameter that does not allow a gap between the outer periphery of the spring 5. The sliding-type fixing member 4 has a connection port 12-3 of a three-way joint so as to cover from the outside of the first rod-shaped portion 3, the second rod-shaped portion 7, the locking ring 2, the spring 5, and the belt-shaped elastic rubber 9. And the stopper 6 are slidably fitted in the length direction of the walking aid. However, when it hits the stopper, it will not slide any further. In this embodiment, as described above, the connection port 12-3 of the grip portion also serves as a stopper for the first rod-shaped portion, but instead of the locking ring 2, a stopper similar to the stopper 6 is provided, One end portion of the elastic rubber may be fixed to the stopper and the sliding position of the fixing member may be restricted.

本実施例の歩行補助具10は以上のように構成され、歩行補助具の握り部1を図2に示すように、重力方向上側にした場合、スライド式の固定部材4は、その端部がストッパ6に突き当たり、第一棒状部3と第二棒状部7との接触部分、スプリング5、帯状の伸縮性ゴム9をそれぞれ覆う位置に固定されるため、使用者が取っ手部を握って、握り部1に重力方向の力を加えても、スプリング5は屈曲できず、第一棒状部3と第二棒状部7とは一直線の状態を維持している(通常モード)。   The walking aid 10 of the present embodiment is configured as described above, and when the grip 1 of the walking aid is set to the upper side in the gravity direction as shown in FIG. Since it hits the stopper 6 and is fixed at a position covering the contact portion between the first rod-shaped portion 3 and the second rod-shaped portion 7, the spring 5, and the belt-shaped elastic rubber 9, the user grasps the grip portion and grips it. Even if a force in the direction of gravity is applied to the portion 1, the spring 5 cannot be bent, and the first rod-like portion 3 and the second rod-like portion 7 are kept in a straight line (normal mode).

一方で、図3に示すように、握り部が上方の位置から反転して石突き8を重力方向上側にした場合、スライド式の固定部材4を三又ジョイントの接続口12−3に突き当たるまで下方にスライドさせると、第一棒状部3と第二棒状部7との接触部分、スプリング5、帯状の伸縮性ゴム9の固定は解除されるため、図7に示すように、使用者が石突き8を握り、重力方向に力を加えると、第一棒状部3に対して、第二棒状部7が屈曲し、スプリング5の反作用力で、使用者に重力方向とは反対方向の力が加わる。このとき、使用者は石突き8を手前に押し下げる動作を行うが、握り部1の2つの取っ手11,11が使用者の手前側2点で接地していること、帯状の伸縮性ゴム9が歩行補助具の進行方向側に接続されていることから、進行方向側に石突き8を押し上げる指向性があり、歩行補助具が左右にぶれることがなく、安定している。2つの取っ手が接地することから、接地面に対して3点以上で支持することになり、更に、昇降時の歩行補助具の位置が安定する(昇降モード、図6、7参照)。   On the other hand, as shown in FIG. 3, when the grip portion is reversed from the upper position and the stone thrusting 8 is on the upper side in the gravity direction, the sliding type fixing member 4 is abutted against the connection port 12-3 of the three-way joint. When sliding downward, the contact portion between the first rod-like portion 3 and the second rod-like portion 7, the spring 5, and the belt-like stretchable rubber 9 are fixed, so that the user can remove the stone as shown in FIG. When the protrusion 8 is gripped and a force is applied in the direction of gravity, the second rod-shaped portion 7 bends against the first rod-shaped portion 3, and the reaction force of the spring 5 causes the user to exert a force in the direction opposite to the gravity direction. Join. At this time, the user performs an operation of pushing down the stone bump 8 toward the front, but the two handles 11 and 11 of the grip portion 1 are grounded at two points on the front side of the user, and the belt-shaped elastic rubber 9 is Since it is connected to the advancing direction side of the walking aid, there is directivity to push up the stone bump 8 on the advancing direction side, and the walking aid does not shake from side to side and is stable. Since the two handles are grounded, they are supported at three or more points with respect to the grounding surface, and the position of the walking aid during the ascent / descent is stabilized (elevation mode, see FIGS. 6 and 7).

図2は、使用者が平坦部を歩行する際に使用する状態、すなわち、通常モードを表している。この通常モードにおいて、使用者は、図5に示すように、握り部1にある取っ手11、11のいずれかを片手で握り、石突き8を接地面に接地させて、自らの体を支える。このとき、スライド式の固定部材4は、その端部がストッパ6に突き当たり、第一棒状部3と第二棒状部7との接触部分、スプリング5、帯状の伸縮性ゴム9をそれぞれ覆う位置で固定されているため、使用者が取っ手11を握って、握り部1に重力方向の力を加えても、スプリングは屈曲せず、歩行補助具は一直線の状態で使用者の体を支えている。図5は、使用者が本歩行補助具を使って、平坦部を歩行する際のイメージ図である。   FIG. 2 shows a state used when the user walks on a flat portion, that is, a normal mode. In this normal mode, as shown in FIG. 5, the user holds one of the handles 11, 11 in the grip portion 1 with one hand, and grounds the stone thruster 8 on the ground surface to support his / her body. At this time, the sliding-type fixing member 4 has an end abutting against the stopper 6 and covers the contact portion between the first rod-shaped portion 3 and the second rod-shaped portion 7, the spring 5, and the belt-shaped stretchable rubber 9. Since it is fixed, even if the user grips the handle 11 and applies a force in the direction of gravity to the grip portion 1, the spring does not bend, and the walking aid supports the user's body in a straight line. . FIG. 5 is an image diagram when the user walks on a flat portion using the walking aid.

図3は、使用者が階段や段差を昇降する際に使用する状態、すなわち、昇降モードを表している。通常モードから、握り部1と石突き8とを上下反転させ、石突き8を重力方向上側にする。次に、スライド式の固定部材4を三又ジョイントの接続口12−3端に突き当たるまでスライドさせて、第一棒状部3と第二棒状部7との接触部分、スプリング5、帯状の伸縮性ゴム9の固定を解除する。使用者は、図6、7のイメージ図に示すように、次の段に握り部1を載せた後、石突き8に体重をかけて、手前下側に押し下げる。スプリング5並びに帯状の伸縮性ゴム9の反作用力によって、石突き8が進行方向に向かって押し上げられ、使用者の上昇力を助ける。使用者はこの繰り返しにより、階段を上ったり、段差を乗り越えたりすることができる。   FIG. 3 shows a state used when the user moves up and down stairs and steps, that is, a lift mode. From the normal mode, the grip 1 and the stone bump 8 are turned upside down, and the stone bump 8 is set to the upper side in the gravity direction. Next, the slide-type fixing member 4 is slid until it contacts the end of the connection port 12-3 of the trifurcated joint, and the contact portion between the first rod-like portion 3 and the second rod-like portion 7, the spring 5, and the belt-like stretchability. The rubber 9 is fixed. As shown in the image diagrams of FIGS. 6 and 7, the user places the grip portion 1 on the next stage, puts the weight on the stone bump 8, and pushes it down to the front side. By the reaction force of the spring 5 and the belt-like stretchable rubber 9, the stone bump 8 is pushed up in the traveling direction to assist the user's lifting force. By repeating this, the user can go up the stairs and get over the steps.

図8は、使用者が椅子やベンチ等に腰掛けた状態から起立する状態、すなわち、起立モードを表している。まず、利用者は、通常モードで本歩行補助具を持つが、平坦部の歩行時と異なる点は、両手で、握り部1の取っ手11、11をそれぞれ握る点である。2つの取っ手11,11を両手で握ることで、両手と、接地面と接地した石突き8とが3点を形成するため、使用者が両手で重力方向に力を加えても、左右に力が逃げてしまうことなく、安定した体勢を保てる。また、石突き8は、球形状であることから、歩行補助具をどのような角度で接地面に接地しても、接地面と石突き8とは摩擦力を発生させることができ、使用者が取っ手11,11に力を加えても、石突き8が前方に滑るリスクが少ない。利用者は、両手で2つの取っ手を握り、腕の力で補助しながら、(a)の状態から(b)の状態に起立することができる。起立後は、取っ手のいずれかを片手で握ることで、通常モードに移行し、歩行補助具を使った歩行ができる。   FIG. 8 shows a state in which the user stands up from a state of sitting on a chair, bench, or the like, that is, a standing up mode. First, the user has the walking aid in the normal mode, but the point different from when walking on the flat part is that the grips 11 and 11 of the grip part 1 are gripped with both hands. By grasping the two handles 11 and 11 with both hands, both hands and the grounding surface 8 that touches the ground surface form three points, so even if the user applies force in the direction of gravity with both hands, Can maintain a stable posture without running away. Further, since the stone bump 8 has a spherical shape, the grounding surface and the stone bump 8 can generate a frictional force regardless of the angle at which the walking aid is grounded on the ground surface. However, even if force is applied to the handles 11, 11, the risk of the stone bump 8 slipping forward is small. The user can stand from the state (a) to the state (b) while holding the two handles with both hands and assisting with the power of the arm. After standing up, hold one of the handles with one hand to shift to normal mode and walk with walking aids.

実施例2
図9は、本発明の歩行補助具の実施例2を表す。本実施例の歩行補助具20は、握り部21、係止リング22、第一棒状部23、スライド式のスリット入り固定部材24、スプリング25、締め付け具26、ストッパ兼締め付け具27、第二棒状部28、石突き29、昇降補助用スプリング30からなる。
Example 2
FIG. 9 shows Example 2 of the walking aid of the present invention. The walking aid 20 of the present embodiment includes a grip portion 21, a locking ring 22, a first rod-shaped portion 23, a sliding slit fixing member 24, a spring 25, a tightening device 26, a stopper and tightening device 27, and a second rod-shaped member. It consists of a portion 28, a stone bump 29, and a lift assisting spring 30.

握り部21、第一棒状部23、スプリング25、第二棒状部28、石突き29は、実施例1と同じである。締め付け具26は、端部に貫通穴26−1を有する。第一棒状部23に締め付け固定し、その管通穴に昇降補助用スプリング30の一端を引っ掛けている。昇降補助用スプリング30の他端は、第二棒状部28に締め付け固定されたストッパ兼締め付け具27の貫通穴27−1に引っ掛けられている。このストッパ兼締め付け具は、昇降補助用スプリング30に長さ方向に力が加わらない位置に調整される。本実施例で昇降補助用スプリング30は、スプリング25と同様にコイルバネを使用しているが、コイルバネに限らず弾性ゴム等の弾性材を採用することも可能である。   The grip 21, the first rod-like portion 23, the spring 25, the second rod-like portion 28, and the stone bump 29 are the same as those in the first embodiment. The fastening tool 26 has a through hole 26-1 at the end. The first rod-like portion 23 is fastened and fixed, and one end of the lifting / lowering assisting spring 30 is hooked into the tube passage hole. The other end of the lift assisting spring 30 is hooked in a through hole 27-1 of the stopper / fastening tool 27 fastened and fixed to the second rod-shaped portion 28. The stopper / fastening tool is adjusted to a position where no force is applied to the lift assisting spring 30 in the length direction. In the present embodiment, the lift assisting spring 30 uses a coil spring in the same manner as the spring 25, but is not limited to a coil spring, and an elastic material such as elastic rubber may be employed.

スライド式のスリット入り固定部材24は、中空、筒状で、長さ方向の側面に全長にスリット24−1がある硬質プラスチック管又はその他の金属管からなる。スプリング25の外周と、隙間ができない程度の内径である。スライド式のスリット入り固定部材24は、第一棒状部23、第二棒状部28、スプリング25の外側から覆うように、締め付け具26とストッパ兼締め付け具27との間で、歩行補助具の長さ方向にスライド自在に嵌合される。このとき、締め付け具26の貫通穴26−1がある突起部26−2が、スライド式のスリット入り固定部材におけるスリット24−1に嵌合するように、スリットの位置を調整する。一方で、ストッパ兼締め付け具27の貫通穴27−1がある突起部27−2はスリットに嵌合しない。   The slide-type fixing member 24 with slits is hollow and cylindrical, and is made of a hard plastic tube or other metal tube having a slit 24-1 on the entire length side surface. The inner diameter of the spring 25 is such that there is no gap between the outer periphery of the spring 25. The sliding-type fixing member 24 with slit is a length of the walking aid between the fastening tool 26 and the stopper / fastening tool 27 so as to cover from the outside of the first rod-like portion 23, the second rod-like portion 28, and the spring 25. It is slidably fitted in the vertical direction. At this time, the position of the slit is adjusted so that the projection 26-2 having the through hole 26-1 of the fastening tool 26 fits into the slit 24-1 in the sliding-type fixing member with slit. On the other hand, the protrusion 27-2 having the through hole 27-1 of the stopper / fastener 27 does not fit into the slit.

そのため、スライド式のスリット入り固定部材24の端部が、ストッパ兼締め付け具27に突き当たると、第一棒状部23と第二棒状部28との接触部分、スプリング25をそれぞれ覆う位置に固定されるため、使用者が取っ手11を握って、握り部20に重力方向の力を加えても、スプリング25は屈曲できず、第一棒状部23、第二棒状部28とは一直線の状態を維持している。一方で、石突き29を重力方向上側にした場合、スライド式のスリット入り固定部材24を、握り部側のストッパに突き当たるまでスライドさせると、第一棒状部23と第二棒状部28との接触部分、スプリング25の固定は解除されるため、使用者が石突き29を握り、重力方向に力を加えると、第二棒状部28に対して、第一棒状部23が屈曲し、スプリング25と、昇降補助用スプリング30の反作用力で、使用者に重力方向とは反対方向の力が加わる。このとき、使用者は石突き29を手前に押し下げる動作を行うが、握り部の2つの取っ手が使用者の手前側2点で接地していること、昇降補助用スプリング30が進行方向側に接続されていることから、進行方向側に石突き29を押し上げる指向性があり、歩行補助具が左右にぶれることがなく、安定している。2つの取っ手が接地することから、接地面に対して3点以上で支持することになり、更に、昇降時の歩行補助具の位置が安定する。
図10は、実施例2の歩行補助具における通常モードから昇降モードへの切り替えを示す。
Therefore, when the end portion of the slide-type fixing member 24 with the slit hits the stopper / clamp 27, the contact portion between the first rod-shaped portion 23 and the second rod-shaped portion 28 and the spring 25 are fixed to the respective positions. Therefore, even if the user holds the handle 11 and applies a force in the gravitational direction to the grip portion 20, the spring 25 cannot be bent, and the first rod portion 23 and the second rod portion 28 are kept in a straight line. ing. On the other hand, when the stone thrust 29 is set to the upper side in the direction of gravity, the sliding-type slit-fixed fixing member 24 is slid until it comes into contact with the stopper on the grip portion side, thereby contacting the first rod-shaped portion 23 and the second rod-shaped portion 28. Since the fixing of the part and the spring 25 is released, when the user grasps the stone bump 29 and applies a force in the direction of gravity, the first rod-like portion 23 is bent with respect to the second rod-like portion 28, and the spring 25 The reaction force of the lift assisting spring 30 applies a force in the direction opposite to the direction of gravity to the user. At this time, the user performs the operation of pushing down the stone bump 29 to the front, but the two handles of the grip are grounded at two points on the front side of the user, and the lifting assist spring 30 is connected to the traveling direction side. Therefore, there is directivity to push up the stone bump 29 on the traveling direction side, and the walking aid does not shake from side to side and is stable. Since the two handles are in contact with the ground, they are supported at three or more points with respect to the ground surface, and the position of the walking aid during the elevation is stabilized.
FIG. 10 shows switching from the normal mode to the lift mode in the walking aid of the second embodiment.

本発明の歩行補助具は、通常歩行モード、起立モード及び昇降モードに切り替え使用可能であり、特別なステップ台を有することなくコンパクトで、軽量に構成することができ、通常の杖としても利用可能性が高い。   The walking aid of the present invention can be switched between the normal walking mode, the standing mode, and the lifting mode, and can be configured to be compact and lightweight without having a special step base, and can also be used as a normal cane.
