Abstract

<P>PROBLEM TO BE SOLVED: To provide a crutch stably shifting the gravity center with the tip of the crutch landed on the ground when going down stairs. <P>SOLUTION: The engagement between a clasp 10 and a hook 11 is disengaged by grasping a lever 12 provided in a grip part 4 and a telescopic device 9 is extended to make a crutch body longer. When the user puts the weight on an armpit rest with a crutch tip rubber landed on the ground, the telescopic device 9 is contracted to make the crutch body shorter and the clasp 10 and the hook 11 are engaged with each other to fix the length of the crutch body. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、身体障害者が一般に用いる医療福祉用の松葉杖の構造に関する。
【0002】
【従来の技術】
従来の医療福祉用松葉杖として一般に使用されている一例を図2に示す。松葉杖1は、頂端の脇当2と、対を成す脚片3aおよび3bと、この脚片対の中間に固定された握り部4と、前記脚片対の下端に挟んで固定された筒状の支柱5と、支柱5の中で長さ位置を鋲あるいはボルト締めにより任意に調節できる伸展棒6と、伸展棒6の下端に取り付けられた杖先ゴム7とで構成されている。(例えば、特許文献1参照。)。

【0004】
【発明が解決しようとする課題】
従来用いられている松葉杖は、平地使用に基づいた長さ調節をするため、段差を降りる場合に杖の長さが足りず、不安定なままで重心を前に移動させなければならないという問題があった。
【0005】
【課題を解決するための手段】
本発明は、この課題を解決するためのもので、従来の松葉杖においては、簡易な操作で松葉杖を伸縮させる機構を取り付けることにより、杖先を段下に着けた状態での、安定した重心移動のみを可能にするものである。
【0006】
【発明の実施の形態】
図1は、本発明による松葉杖の構造の1実施例を示すもので、以下図について説明する。
1は松葉杖本体で、脇当2を頂端とする平衡な一対の脚片3a,3bを配し、この脚片対3a−3bの中間部に握り部4取り付ける。
【0007】
また、脚片対3a−3bを折り曲げることによって狭くなった下端の隙間に筒状の支柱5を取り付けて固定し、この支柱5の上端に伸縮器9の上側を固定し、伸縮器9の下端の位置が上下するようにする。
【0008】
ストッパー8を、伸展棒6の長さおよび松葉杖全体の長さを考慮して支柱5の上端から少し下がった位置に固定する。ストッパー8は図3に示すように、中心部に空洞を設け伸縮器9の下端がストッパー8の位置よりも下に位置することができるようにする。伸縮器9は、例えばコイルバネなどの弾性体を用いる。
【0009】
前記伸縮器9の下端と伸展棒6の上端を固定し、伸縮器の伸縮にあわせて松葉杖の長さが伸縮するようにする。伸展棒6の太さは前記ストッパー8の中心に空けた穴よりも太くし、伸展棒がストッパー8の位置で必ず止まるようにする。
【0010】
伸展棒6の中間位置にはこの伸展棒の上端がストッパー8の位置まで後退した場合でも、支柱5の中に入らない位置にカギ10を取り付け、前期伸展棒6の下端に杖先ゴムを取り付ける。
【0011】
また、支柱5の下端にはフック11を前記カギ10と噛み合う位置に調整して取り付ける。
【0012】
握り部4にはレバー12を取り付け、このレバー12を握ることによって脚片3bの内側に這わせたワイヤー13を通して前記フック11を反らせるように支店支持することにより、前記カギ10との噛み合わせを解除することができる。カギ10の構造は位置を固定するためのもので、図示ような形状あるいはラック状でもよい。ここでは1ヶ所に固定する図で示したが、複数個設置することで、固定位置に幅を持たせることが出来ることは明かである。
【発明の効果】
本発明により、レバー12を握ることによりカギ10とフック11の噛み合いを外し、伸縮器9が伸びることによって松葉杖本体を伸長し、杖先ゴムを地面に着けた状態で脇当4に体重を乗せることにより、伸縮器9が縮み、松葉杖本体が縮長され、前記カギ10と前記フック11が噛み合うことによって松葉杖本体の長さが固定されることにより、速やかに松葉杖の長さを伸張させることができる。これによって、階段の下降時などにおいて、松葉杖の先を地面に着けた状態での安定した重心移動が可能になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to the structure of crutches for medical and welfare generally used by persons with disabilities.
[0002]
[Prior art]
FIG. 2 shows an example generally used as a conventional crutch for medical welfare. The crutch 1 has a side abutment 2 at the top end, a pair of leg pieces 3a and 3b, a grip 4 fixed in the middle of the pair of leg pieces, and a cylindrical shape fixed to the lower end of the pair of leg pieces. , An extension bar 6 whose length position can be arbitrarily adjusted by fastening with a stud or a bolt, and a cane rubber 7 attached to a lower end of the extension bar 6. (For example, refer to Patent Document 1).
[0003]
[Patent Document 1]
JP 2000-316925 A (FIG. 1)
[0004]
[Problems to be solved by the invention]
Conventional crutches have a problem that the length of the cane is not enough when going down a step because the length of the crutch is adjusted based on the use of flat ground, and the center of gravity must be moved forward with being unstable. there were.
[0005]
[Means for Solving the Problems]
The present invention is intended to solve this problem. In a conventional crutch, a mechanism for extending and contracting the crutch by a simple operation is attached, so that the center of gravity of the crutch can be moved stably with the tip of the crutch under the step. It only makes it possible.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an embodiment of the structure of a crutch according to the present invention, which will be described below.
A crutch 1 is provided with a pair of balanced leg pieces 3a and 3b having the abutment 2 as a top end, and the grip portion 4 is attached to an intermediate portion of the leg pair 3a-3b.
[0007]
Further, a cylindrical column 5 is attached and fixed to the gap at the lower end narrowed by bending the leg pair 3a-3b, and the upper side of the expander 9 is fixed to the upper end of the column 5, and the lower end of the expander 9 is fixed. So that the position moves up and down.
[0008]
The stopper 8 is fixed at a position slightly lower than the upper end of the column 5 in consideration of the length of the extension bar 6 and the entire length of the crutch. As shown in FIG. 3, the stopper 8 is provided with a cavity at the center so that the lower end of the extender 9 can be located below the position of the stopper 8. The expander 9 uses an elastic body such as a coil spring.
[0009]
The lower end of the telescopic device 9 and the upper end of the extension bar 6 are fixed so that the length of the crutches expands and contracts in accordance with the expansion and contraction of the expander. The thickness of the extension rod 6 is made larger than the hole made in the center of the stopper 8 so that the extension rod always stops at the position of the stopper 8.
[0010]
At the middle position of the extension rod 6, even if the upper end of the extension rod retreats to the position of the stopper 8, a key 10 is attached at a position where it does not enter the support post 5, and a cane rubber is attached to the lower end of the extension rod 6 in the previous period. .
[0011]
Further, the hook 11 is attached to the lower end of the column 5 so as to be adjusted to a position where the hook 11 is engaged with the key 10.
[0012]
A lever 12 is attached to the grip portion 4, and the hook 12 is supported by a branch so that the hook 11 is warped through a wire 13 crawled inside the leg piece 3 b by gripping the lever 12, thereby engaging with the key 10. Can be canceled. The structure of the key 10 is for fixing the position, and may have a shape as shown or a rack shape. Here, the fixing position is shown in the figure, but it is apparent that the fixing position can be given a width by installing a plurality of fixing positions.
【The invention's effect】
According to the present invention, the key 10 and the hook 11 are disengaged from each other by grasping the lever 12, and the crutch body is extended by extending the extender 9, and the weight is put on the armrest 4 with the cane rubber attached to the ground. Thereby, the stretcher 9 is contracted, the crutch main body is contracted, and the key 10 and the hook 11 are engaged with each other, so that the length of the crutch main body is fixed, so that the length of the crutch can be quickly increased. it can. This allows stable movement of the center of gravity with the tip of the crutch attached to the ground, such as when descending stairs.
