Description

本発明は、体の不自由な人又は老人等が歩行しあるいは体を支持するために使用される杖及び杖の先端に装着される杖用石突に関する。   The present invention relates to a cane used for a physically handicapped person or an elderly person to walk or support the body, and a cane protrusion attached to the tip of the cane.

従来、体の不自由な人又は老人が歩行する際あるいは体を支持するために、杖が使用される。一般的な杖は、図示省略するが、使用者の身長の半分程度の長さの支柱及びこの支柱の上端に設けられ使用者が握るための把手からなる杖本体と、支柱の下端に接続され地面へ接触する石突と、を備えて構成されている。   Conventionally, a walking stick is used when a handicapped person or an elderly person walks or supports the body. Although a general cane is not shown in the figure, it is connected to a cane body consisting of a support column about half the height of the user and a handle provided at the upper end of the support unit and gripped by the user, and the lower end of the support column. And a stone bumper that comes into contact with the ground.

杖は、体重の２割まで支える効果が必要であるといわれている。そのため、杖本体は通常、要求される強度や耐久性を達成するために、樫などの硬質な木材やアルミニウム合金などの剛性の金属材，硬質の合成樹脂材料等によって形成されている。このような杖によれば、体の不自由な人又は老人が歩行する際などに、歩行を補助又は体を支持することができる。   It is said that the cane needs to support up to 20% of its weight. For this reason, the cane body is usually made of hard wood such as cocoons, a rigid metal material such as an aluminum alloy, a hard synthetic resin material, or the like in order to achieve required strength and durability. According to such a cane, when a physically handicapped person or an elderly person walks, walking can be assisted or supported.

また、石突は、例えばゴムなどの摩擦係数が高い弾性樹脂素材からなり、支柱の下端に嵌合されていて接地部分には溝などの滑り止め加工がなされている。   Further, the stone bump is made of an elastic resin material having a high friction coefficient such as rubber, and is fitted to the lower end of the support column, and a non-slip process such as a groove is made on the ground contact portion.

上述のような従来の杖は、杖本体が要求される強度や耐久性を達成するために、硬質の金属材，硬質の合成樹脂材料等によって形成されている。そのため、接地時の、支柱に平行な方向への反力が大きく、使用者は杖を突くたびに接地の衝撃を感じ、場合によっては手、腕や頭部にまで及ぶ痛みや衝撃を生じることもある。   The conventional cane as described above is formed of a hard metal material, a hard synthetic resin material, or the like in order to achieve the strength and durability required for the cane body. For this reason, the reaction force in the direction parallel to the support is large when touching the ground, and the user feels the impact of touching every time he or she wands, and in some cases may cause pain or shock reaching the hand, arm or head. There is also.

また、従来の石突は、弾性樹脂素材からなるものの、弾性変形範囲は素材の特性により限定されるし、支柱に平行な方向への弾性変形範囲を大きくするために弾性素材の厚みを増したような場合には、支柱に平行な方向のみならず支柱に垂直な方向への弾性変形範囲をも大きくしてしまう結果となり、この場合、杖が横にずれたような感覚を生じ使用感が低下する。   In addition, although conventional stone bumps are made of an elastic resin material, the elastic deformation range is limited by the characteristics of the material, and the thickness of the elastic material seems to be increased in order to increase the elastic deformation range in the direction parallel to the column. In this case, the elastic deformation range in the direction not only in the direction parallel to the support column but also in the direction perpendicular to the support column is increased. To do.

本発明は、上記問題点に鑑みてなされたものであり、接地の衝撃を緩和させることができる、杖用石突及びこれを連結してなる杖を提供することを目的とする。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a cane protrusion and a cane formed by connecting the cane protrusions, which can reduce the impact of ground contact.

上記目的を達成するため、本発明の杖用石突は、下端側に鍔を有する棒状の軸と、鍔の上面に当接し軸に沿って伸縮する弾性部材と、杖本体への取付部を有していて弾性部材の上部に当接して軸に沿って摺動するスライド筒と、軸の上端側に固設され弾性部材及びスライド筒が軸から脱離することを防ぐ抜け止め部材とを備えたことを特徴とする。   In order to achieve the above object, the cane protrusion of the present invention has a rod-shaped shaft having a heel on the lower end side, an elastic member that contacts the upper surface of the heel and expands and contracts along the shaft, and an attachment portion to the wand body. And a slide cylinder that slides along the shaft in contact with the upper portion of the elastic member, and a retaining member that is fixed to the upper end side of the shaft and prevents the elastic member and the slide cylinder from being detached from the shaft. It is characterized by that.

弾性部材は、ゴミの付着又は雨水等の浸入のため蛇腹状の可撓性素材で覆われることが望ましい。   The elastic member is preferably covered with a bellows-like flexible material for adhering dust or rainwater.

杖本体への取付部は、スライド筒の外面に施されたネジきりであってもよく、この場合杖本体の下端内側に形成した対応する内ネジと噛合させることで、石突を杖本体に脱着自在に取り付けることができる。   The attachment part to the cane body may be a screw thread applied to the outer surface of the slide cylinder. In this case, the stone bump is attached to and detached from the cane body by engaging with the corresponding internal screw formed inside the lower end of the cane body. Can be attached freely.

また、本発明の杖は、下端側に鍔を有する棒状の軸と、鍔の上面に当接し軸に沿って伸縮する弾性部材と、杖本体への取付部を有していて弾性部材の上部に当接して軸に沿って摺動するスライド筒と、軸の上端側に固設され弾性部材及びスライド筒が軸から脱離することを防ぐ抜け止め部材とを備えた杖用石突を杖本体の下端に連結して構成される。   The cane of the present invention has a rod-shaped shaft having a heel on the lower end side, an elastic member that contacts the upper surface of the heel and expands and contracts along the shaft, and an attachment portion to the wand body. A cane body having a slide barrel that slides along the shaft in contact with the shaft, and an elastic member that is fixed on the upper end side of the shaft and prevents the slide tube from being detached from the shaft. Connected to the lower end of the

本発明の杖用石突によれば、使用者が杖を突いた際に生じる反力が、軸の下端から鍔を介して弾性部材に伝わり、この弾性部材からスライド筒の取付部を介して杖本体に伝達されるところ、このスライド筒が弾性部材に当接しているため、衝撃が弾性部材により緩和され、接地の衝撃を緩和させることができる。また、スライド筒は軸に沿って、すなわち上下方向に沿って摺動するから、杖の使用感を損なうことはない。   According to the cane protrusion of the present invention, the reaction force generated when the user pokes the cane is transmitted from the lower end of the shaft to the elastic member through the heel, and from this elastic member through the mounting portion of the slide cylinder When this slide cylinder is in contact with the elastic member, the impact is relieved by the elastic member and the grounding impact can be relieved. Further, since the slide cylinder slides along the axis, that is, along the vertical direction, the feeling of use of the cane is not impaired.

弾性部材が蛇腹状の可撓性素材で覆われる場合には、弾性部材が軸に沿って摺動する際にゴミなどの混入や雨水の浸入などを防ぐことができる。   In the case where the elastic member is covered with a bellows-like flexible material, it is possible to prevent dust and the like from entering the rain water and the like when the elastic member slides along the shaft.

取付部がスライド筒の外面に施されたネジきりである場合には、既存の杖の下端にこのねじ切りに対応するねじ切りを施すことで、この杖用石突を後付けすることができる。   In the case where the mounting portion is a screw thread applied to the outer surface of the slide cylinder, this cane can be retrofitted by performing threading corresponding to this threading on the lower end of the existing cane.

本発明の杖によれば、衝撃が弾性部材により吸収されて接地の衝撃を緩和させることができる。また、スライド筒は軸に沿って、すなわち上下方向に沿って摺動するから、杖の使用感を損なうことはない。   According to the cane of the present invention, the impact is absorbed by the elastic member, and the grounding impact can be reduced. Further, since the slide cylinder slides along the axis, that is, along the vertical direction, the feeling of use of the cane is not impaired.

The pin 82 is inserted into these holes while the holes 81 are aligned with the holes 52 of the shaft 5, so that the retaining member 8 is firmly attached to the shaft 5.

以上のように構成された杖用石突３を杖本体２に連結することで、具体的にはスライド筒７のネジきり７１を杖本体２の下端内面施されたねじ切り２２に螺着することにより、杖１が完成する。杖本体２は、既存の杖の下端部を杖用石突３に相当する長さ分だけ切断して、ねじ切りを施すだけで作製できるから、使用者の使い慣れた杖をそのまま利用することができる。   By connecting the canopy protrusion 3 configured as described above to the cane body 2, specifically, by screwing the screw thread 71 of the slide cylinder 7 to the threading 22 provided on the inner surface of the lower end of the cane body 2. The cane 1 is completed. The cane body 2 can be produced by simply cutting the lower end of the existing cane by a length corresponding to the cane protrusion 3 and threading it, so that the cane familiar to the user can be used as it is.

このような杖用石突３を装着した杖１を使用する場合、使用者が杖１を地面に突いた際に生じる反力が、軸５の下端から鍔５１を介してコイルばね６に伝わり、このコイルばね６からスライド筒７の取付部７１を介して杖本体２に伝達される。この際、スライド筒７がコイルばね６に当接してコイルばね６を圧縮するため、杖の把手２２が使用者の荷重によって適度に下方へ沈み込んで圧縮することで、接地の衝撃を緩和させることができる。また、スライド筒７は軸５に沿って、すなわち杖１の上下方向に沿って摺動するから、杖１の横方向へのずれがなく、使用感を損なうことはない。   When the cane 1 equipped with such a cane protrusion 3 is used, a reaction force generated when the user projects the cane 1 on the ground is transmitted from the lower end of the shaft 5 to the coil spring 6 via the flange 51, This is transmitted from the coil spring 6 to the cane body 2 via the mounting portion 71 of the slide cylinder 7. At this time, since the slide cylinder 7 abuts on the coil spring 6 and compresses the coil spring 6, the handle 22 of the cane sinks downward and compresses appropriately by the load of the user, thereby reducing the impact of grounding. be able to. Further, since the slide cylinder 7 slides along the shaft 5, that is, along the vertical direction of the cane 1, there is no displacement of the cane 1 in the lateral direction and the feeling of use is not impaired.

以上説明したように、本発明は、杖本体２に杖用石突３を連結し、歩行する際あるいは体を支持する時、使用者の体荷重に基づく地面の衝撃的反力を緩和させるもので、その主旨を逸脱しない範囲内において様々な形態で実施することができる。例えば、杖の材質は木材であってもよいし、滑り止め等の部品の形状は適宜設計し得る。さらに、杖用石突と杖本体との連結方法及び軸と滑り止めとの連結方法は、本実施形態で説明したねじ切りを介する螺着に限られず、滑り止めや杖本体もしくは他のチューブ状の弾性樹脂素材などの弾性及び摩擦を利用して単に嵌合して連結するものであってもよいし、接着、溶接など、様々な態様が可能である。また、金属製の部材には、錆対策として、表面にニッケルメッキ処理が施されることが望ましい。   As described above, the present invention is to relieve the impact reaction force of the ground based on the user's body load when the cane body 3 is connected to the cane body 2 and when walking or supporting the body. The present invention can be implemented in various forms without departing from the spirit of the invention. For example, the material of the cane may be wood, and the shape of parts such as anti-slip can be appropriately designed. Furthermore, the connecting method between the cane protrusion and the cane body and the connecting method between the shaft and the slip stopper are not limited to the screwing through the thread cutting described in the present embodiment, but the slip stopper, the cane body, or other tube-like elasticity. It may be one that is simply fitted and connected using elasticity and friction of a resin material or the like, and various modes such as adhesion and welding are possible. Moreover, it is desirable that the surface of the metal member be subjected to nickel plating as a countermeasure against rust.
