この発明は義足、特に足首の俯仰角度の変更調節機構の
改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prosthetic leg, particularly to an improvement in a mechanism for changing and adjusting an angle of elevation of an ankle.
義足において足首の関節が僅かに俯仰方向に動く構造の
ものは、足首の関節か常態（接地向が水平位）に復元す
るようにしである。Prosthetic legs that allow the ankle joint to move slightly in the upward and downward direction are designed to allow the ankle joint to return to its normal state (the direction of contact with the ground is horizontal).
ところで履物を履く際や坐る際、或は踵の高い靴を履い
たり坂道をのほりおりする際の足首の俯仰角度は特に大
とする必要がある。Incidentally, when putting on footwear, sitting, wearing high-heeled shoes, or climbing down a slope, the angle of elevation of the ankle must be particularly large.
ところが第４図に示す従来の義足は、下腿部（イ）と足
部（ロ）が関節（ハ）で連結され、同関節に形成される
間隙に）には軟質弾性片（ホ）が°介在固定されて俯仰
角に変更しても正常位に復元するようにしてあり、又希
望の俯仰角度に固定するには楔（へ）を打込んでおり、
楔の打込み操作も自分でするには困難性がある。However, in the conventional prosthetic leg shown in Figure 4, the lower leg (A) and foot (B) are connected by a joint (C), and a soft elastic piece (E) is placed in the gap formed at the joint. ° Even if the interposition is fixed and the elevation angle is changed, it will return to the normal position, and a wedge is driven in to fix it at the desired elevation angle.
It is also difficult to drive the wedge by yourself.
この発明は足部の俯仰角度調節の従来の問題点を解決し
たもので、その目的と、するところは足部の俯仰角度を
随時簡単に、且つ微細に調節し得る義足とするにある。This invention solves the conventional problem of adjusting the elevation angle of the foot, and its purpose is to provide a prosthetic leg that can easily and finely adjust the elevation angle of the foot at any time.
この発明は、下腿部に減速モーターで１回転するねじ軸
を設けてこのねじ軸にリンクの一端に連結したナツトを
装着し、ねじ軸の回転でナツトが昇降し、足部の前寄り
部分を前記リンクの他端に連結して足部を希望の俯仰角
に調整することを特徴とする。In this invention, a screw shaft that is rotated once by a deceleration motor is provided in the lower leg, and a nut connected to one end of the link is attached to this screw shaft.The rotation of the screw shaft moves the nut up and down, and is connected to the other end of the link to adjust the foot portion to a desired elevation angle.
以下この発明の実施例を添付図面に基づいて説明すれば
、１は大腿ソケット、２は関節３を介して連結される下
腿部であ°る。Embodiments of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 indicates a thigh socket, and 2 indicates a lower leg portion connected via a joint 3.
下腿部２はパイプ４からなり、パイプ内に減速娑−ター
５が装填してあり、その駆動軸６に連結されたねじ軸７
はパイプ下端から突出している。The lower leg part 2 consists of a pipe 4, in which a reducer 5 is loaded, and a screw shaft 7 connected to a drive shaft 6 of the reducer 5.
protrudes from the bottom end of the pipe.
ねじ軸７にはナツト８が装着されこれにリンク９の一端
が連結してあり、リンクの他端は足部取付台１０におけ
る足首関節１１より前部に連結しである。A nut 8 is attached to the screw shaft 7, and one end of a link 9 is connected to the nut 8, and the other end of the link is connected to a portion of the foot mount 10 in front of the ankle joint 11.
１２．１３はねじ軸７の上下端部を軸承する固定台、１
４は両固定台を結合する支柱、１５は下部闇定台１３に
垂下した、足部取付台１０の取付部である。１６は足部
である。 。12.13 is a fixed base that supports the upper and lower ends of the screw shaft 7;
Reference numeral 4 designates a column that connects both fixed bases, and 15 represents a mounting portion of the foot mounting base 10 that hangs down from the lower fixed base 13. 16 is a foot portion. .
減速モーター５は大腿ソケット１の外面に設けたトグル
スイッチ１７により駆動され、つまみ１８を図示のよう
に後側に倒すと正回転、前方に倒すと逆回転し中央位と
することで回転が停止する。The deceleration motor 5 is driven by a toggle switch 17 provided on the outer surface of the thigh socket 1, and when the knob 18 is tilted to the rear as shown in the figure, it rotates in the forward direction, when it is tilted forward, it rotates in the reverse direction, and when it is in the center position, the rotation stops. do.
電源はパイプ４内に装填される。A power source is loaded into the pipe 4.
この発明は上記したような構造であり、この義足は大腿
ソケツ司こ付設したスイッチを操作することで減速モー
ターが正逆回転し連結されたねじ軸が回転するとナツト

でその角度に固定されて、坂道を歩く際従来の義足に比
し著しく容易になり、かゾんだり坐す際、或は踵の高い
靴をはいた際等の操作も従来の義足に比し容易である等
の効果がある。This invention has the above-mentioned structure, and by operating a switch attached to the thigh socket, the deceleration motor rotates forward and backward, and when the connected screw shaft rotates, the nut moves up and down to close one end of the link. As you press down or pull up, the tip of the foot changes to the angle of depression or elevation, and when you reach the desired angle, return the switch to the neutral position and it will be fixed at that angle. It is much easier to operate than conventional prosthetic legs, and it is easier to operate when sleeping, sitting, or wearing high-heeled shoes.
尚ナツトをポールナツトとすることにより摩耗が少なく
て長寿命となし得る。In addition, by using a pole nut as the nut, there is less wear and a long life can be achieved.
