Description
本発明は、杖の先に取り付けられる石突きに関する。 The present invention relates to a stake attached to the tip of a cane.
視覚障害者，老人，登山者等が歩行の補助として使用する杖の先に石突きが取り付けられている。
この石突きは、路面に繰り返し当たることから摩耗や傷が付きやすく、交換が必要な部品である。
例えば、視覚障害者が使う白杖は、周囲に視覚障害者であることを知らせるとともに、使用者が石突きで路面の様子を知り、前方や足下の安全を確認するのに重要である。
このような石突きは、路面を触擦し外界の情報を振動として知覚するために、従来は使用中に外れることがないようにシャフトの先端に接着剤で固定されている。
特許文献１には、路面に突っかかりにくく、疲れずに速く歩行できる盲人安全杖として竿部の先に弾性部材を取り付け、さらにその外面に殻部材を取り付けたものを開示するが、やはりこの弾性部材は杖の先の取付部材に接着してあり、殻部材は弾性部材に接着したものである。
しかし、このように杖のシャフト部の先端に接着固定した石突きを交換するには、専門業者に送付し交換してもらわなければならず、自分で交換できないためにその間は予備の白杖を使用しなければならなかった。
A cane is attached to the tip of a cane used by the visually impaired, the elderly, and climbers to assist walking.
This pebbles is a part that needs to be replaced because it easily wears and scratches because it repeatedly hits the road surface.
For example, a white cane used by a visually impaired person is important for notifying the surroundings that the person is visually impaired and for the user to know the condition of the road surface through a stone stake and to confirm the safety of the front and feet.
Such a stone stake is conventionally fixed to the tip of the shaft with an adhesive so as not to come off during use in order to rub the road surface and perceive the external information as vibration.
Patent Document 1 discloses an elastic member attached to the tip of a rod portion and a shell member attached to the outer surface of the rod as a blind safety cane that does not easily hit the road surface and can walk quickly without getting tired. The member is adhered to the attachment member at the tip of the cane, and the shell member is adhered to the elastic member.
However, in order to replace the butt that is adhesively fixed to the tip of the cane's shaft in this way, you must send it to a specialist and have it replaced. Had to use.
本発明は、路面の状況を触擦しやすく、交換が容易な杖の石突きの提供を目的とする。 It is an object of the present invention to provide a cane stake that can be easily touched on the road surface and can be easily replaced.
本発明に係る石突きは、シャフトの先端部に取り付けた弾性部材と、弾性部材又はシャフトに固定した取付部材と、前記弾性部材の外側に装着するとともに前記取付部材に係止着脱自在の石突き本体部を備えたことを特徴とする。
杖はグリップ，シャフト，シャフトの先端の石突きからなるが、本発明はこの石突きを自分でも交換可能にしたものである。
石突きは、路面を繰り返し突き又は触れ廻し使用するものであり、ネジやピンで固定すると使用中に外れる恐れがあることから、本発明は石突きをシャフトに係止着脱自在にしたものであり、取付部材と石突き本体部との係止着脱は、一方に係止凸部、他方に係止凹部を有する構成からなるのが好ましい。
A stud according to the present invention includes an elastic member attached to a tip portion of a shaft, an attachment member fixed to an elastic member or a shaft, and a stud that is attached to the outside of the elastic member and is attachable to and detachable from the attachment member. It is characterized by having a main body.
The cane comprises a grip, a shaft, and a pebbles at the tip of the shaft. The present invention allows the pebbles to be replaced by oneself.
The stone butt is used by repeatedly pushing or touching the road surface, and if it is fixed with screws or pins, it may come off during use. It is preferable that the attachment/detachment of the mounting member and the main body of the stone butt is configured such that one side has a locking convex portion and the other side has a locking concave portion.
本発明に係る石突きは、シャフトの先端に弾性部材を介して交換可能に石突き本体部を取り付けたので、２００Ｈｚ以上の振動伝達を抑えることができ、視覚障害者にも使用しやすく、路面状況に応じて石突き本体部を交換したり、消耗品として取り換えも容易である。 In the stone butt according to the present invention, since the stone butt main body is replaceably attached to the tip of the shaft through the elastic member, it is possible to suppress the vibration transmission of 200 Hz or more, and it is easy for a visually impaired person to use, and a road surface. Depending on the situation, it is easy to replace the stone head main body or replace it as a consumable item.
本発明に係る石突きの構造例を以下図に基づいて説明する。
杖は、図３に示すようにグリップ３０にシャフト２０を連結し、このシャフト２０の先端に石突きを取り付けたものである。
石突き１０の構造例を図１，２に示す。
シャフト２０の先端部にゴム弾性材からなる弾性部材１２を取り付ける。
実施例では、シャフト２０の先端部にフランジ状の抜け止め部２０ａを有する例になっているが、シャフトの先端に弾性部材１２を取り付けることができるのであれば、これに限定されない。
シャフト２０は、アルミや炭素繊維等が使用されている。
弾性部材１２は、中央部にシャフト２０の挿通孔１２ａを有する略円筒状であり、上部に取付部材１３の固定部１２ｂが段差状に設けてある。
取付部材１３は、リング状の形状からなり、石突き本体部１１を着脱自在に係止固定する凹部１３ａと、弾性部材１２の上面に内側方向のつば部１３ｃと、弾性部材１２の固定部１２ｂに嵌め込むための嵌込部１３ｂを有する。
弾性部材の固定部１２ｂと取付部材１３の嵌込部１３ｂとの間に接着剤を塗布し、接着固定する。
なお、弾性部材１２とシャフト２０との間も接着固定する。
この状態を図１（ｃ），（ｄ）に示す。
石突き本体部１１は、硬質プラスチック等の樹脂成形品であり、弾性部材の先端部及び外周部を覆うように装着する装着凹部１１ｂと、取付部材の凸部１３ａに係止する凹部１１ｃを有する。
また、凹部１１ｃの上面は、石突き本体部１１が弾性変形して取付部材１３に係止しやすいように内側が下方に位置する傾斜部１１ｄを設けてある。
本実施例では、石突き本体部１１の先端部１１ａがキノコ形状になっているが、これに限定されない。
An example of the structure of the stone butt according to the present invention will be described below with reference to the drawings.
As shown in FIG. 3, the walking stick has a shaft 20 connected to a grip 30, and a butt end is attached to the tip of the shaft 20.
An example of the structure of the pebbles 10 is shown in FIGS.
An elastic member 12 made of a rubber elastic material is attached to the tip of the shaft 20.
In the embodiment, the tip of the shaft 20 has the flange-shaped retaining portion 20a, but the invention is not limited to this as long as the elastic member 12 can be attached to the tip of the shaft.
The shaft 20 is made of aluminum, carbon fiber, or the like.
The elastic member 12 has a substantially cylindrical shape having an insertion hole 12a for the shaft 20 in the central portion, and a fixing portion 12b of the mounting member 13 is provided in a stepped shape on the upper portion.
The mounting member 13 has a ring shape, and has a concave portion 13a for removably locking and fixing the stone butt main body portion 11, a flange portion 13c inward on the upper surface of the elastic member 12, and a fixing portion 12b of the elastic member 12. It has a fitting portion 13b for fitting into.
An adhesive is applied between the fixing portion 12b of the elastic member and the fitting portion 13b of the mounting member 13 to fix them by adhesion.
The elastic member 12 and the shaft 20 are also bonded and fixed.
This state is shown in FIGS. 1(c) and 1(d).
The stone butt main body 11 is a resin molded product such as hard plastic, and has a mounting recess 11b that is mounted so as to cover the distal end portion and the outer peripheral portion of the elastic member, and a recess 11c that locks with the convex portion 13a of the mounting member. ..
Further, the upper surface of the concave portion 11c is provided with an inclined portion 11d whose inner side is located downward so that the stone projection main body portion 11 is elastically deformed and is easily locked to the mounting member 13.
In the present embodiment, the tip end portion 11a of the stone butt body portion 11 has a mushroom shape, but is not limited to this.
シャフト２０に加速度計をつけて石突き本体部１１を擦りつけた時の振動特性（ＦＦＴ解析）を図４のグラフに示す。
掌に受ける感覚線維の振動値（１２０〜１４０Ｈｚ）に近い振動数付近に、単峰性のパワースペクトラムの大きなピークが現れている。
これにより、白杖等の使用者とっては使いやすいことが分かる。
The graph of FIG. 4 shows the vibration characteristics (FFT analysis) when the accelerometer is attached to the shaft 20 and the stone head main body 11 is rubbed.
A large peak of the unimodal power spectrum appears near the frequency close to the vibration value (120 to 140 Hz) of the sensory fiber received by the palm.
From this, it can be seen that it is easy for a user of a white cane or the like to use.
