Description

本考案は、杖の構造方面の技術分野に関し、特に、杖に良好な震動緩衝効果及び良好な安定性を持たせる杖の脚台構造に関する。   The present invention relates to the technical field of the structure direction of a cane, and in particular, relates to a cane pedestal structure that gives the cane a good vibration damping effect and good stability.

台湾公告第212935、370873号専利は、従来の杖の脚台構造を開示しており、その底台は、何れも周辺が錐面を呈する円柱状であるので、底部の凹溝を利用し、それに支持力を受けた時に変形を生じさせ、震動緩衝効果を有するが、その形状が底台の弾性変形量が微小であることに制限を受け、その震動緩衝効果が良好でない。更に、その底面積が小さく且つ円形を呈するので、地面と接触時に滑動が生じ易く、支持が不安定であり、底台の体積を増大し、安定性を増加すれば、材料コストが大幅に上昇し、また、杖の重量を増加し、使用上の不便を招く。また、その球状端を利用した該凹弧溝との組み合わせは、振動角度が大きいことにより人体の重心を効率的に支持することができなくなり易い。特に、該底台の振動後、元の位置に自動回復しないので、次に地面に支持する時に底台の角度が地面と異なり、酷ければ反対となり、該杖の支持過程において、ごつごつした不順動作を発生し、使用の効果に影響を及ぼし、更には危険を招く。また、該杖を放した時、支持ロッドも一側に傾き、地面上に直立に置かれることができず、別途杖挟みによりそれを挟み抑える必要がある。   Taiwan Public Notice No. 221935,370873 discloses a conventional pedestal structure of a cane, and since the bottom is a cylindrical shape with a conical surface at the periphery, a groove on the bottom is used. When it receives support force, it is deformed and has a vibration damping effect, but its shape is limited by the fact that the amount of elastic deformation of the base is very small, and its vibration damping effect is not good. In addition, since the bottom area is small and circular, sliding is likely to occur when in contact with the ground, the support is unstable, the volume of the base is increased, and the stability is increased. In addition, the weight of the cane is increased, resulting in inconvenience in use. Further, the combination with the concave arc groove using the spherical end tends to make it difficult to efficiently support the center of gravity of the human body due to the large vibration angle. In particular, since the base is not automatically restored to its original position after the vibration of the base, the angle of the base is different from the ground when it is supported on the ground next time. Generates movement, affects the effect of use, and further poses a danger. Also, when the cane is released, the support rod is also tilted to one side and cannot be placed upright on the ground, and it is necessary to hold it separately by pinching the cane.

台湾公告第386378、477184、M345514号専利は、他の従来の杖の脚台構造を開示しており、それは、脚パッド内部のバネ又は脚パッド周壁の環状凹溝を利用し、その脚パッドの底部を振動後、原状回復させ、上記支持過程中のごつごつした不順動作が発生しない。しかしながら、その脚パッドが支持力を受け発生する変形量が小さいので、その震動緩衝効果が良好でない。公告第386378号の専利は、圧縮量が比較的大きなバネを利用し、比較的良好な震動緩衝効果を持たせているが、その周囲を覆う脚パッドが変形量が過大になり易く、長期の伸縮により破裂を発生する状況があり、その構造も比較的複雑である。また、それは、何れも依然として上記底面積が小さく、且つ円形が発生する支持が安定せず、底部の体積の増加がコストの大幅に上昇させ、杖の重量を増加させ、使用に不便である問題を招く。   Taiwan Publication No. 386378, 477184, M345514 Patent Disclosure discloses another conventional cane pedestal structure, which utilizes a spring inside the leg pad or an annular groove in the leg pad peripheral wall, After the bottom is vibrated, it is restored to its original state, and no erratic irregular operation occurs during the above support process. However, since the leg pad receives a supporting force and the amount of deformation generated is small, the vibration damping effect is not good. The exclusive patent No. 386378 uses a spring with a relatively large amount of compression to provide a relatively good vibration damping effect, but the leg pad that surrounds it tends to be excessively deformed, resulting in a long-term There are situations in which rupture occurs due to expansion and contraction, and the structure is relatively complex. In addition, it is a problem that the bottom area is still small and the support in which the circular shape is generated is not stable, the increase in the volume of the bottom part greatly increases the cost, increases the weight of the cane, and is inconvenient to use. Invite.

台湾公告第M338069号専利は、他の従来の杖の脚台構造を開示しており、その底部は、三脚ロッドで地面に支持し、その支持面積を増加し、上記良好な支持安定性を有し、脚台の材料コストを増加させない。しかしながら、その全体と支持ロッドは、剛性を呈し、震動緩衝効果を有さないので、使用者は、地面の反作用力を完全に受け、使用上に快適でない。その脚台と支持ロッドは、上記のように、球状端と該凹弧溝の組み合わせを利用しているので、人体の重心を効率的に支持できず、支持過程が円滑でなく、容易に傾き、地面上に直立に置かれず、別途杖挟みにより挟み抑えることが必要であるという問題を有する。   Taiwan Patent No. M338069 patent document discloses another conventional cane base structure, the bottom of which is supported by the ground with a tripod rod, increases the support area, and has the above-mentioned good support stability. And does not increase the material cost of the footrest. However, since the whole and the support rod exhibit rigidity and do not have a vibration damping effect, the user is completely subjected to the reaction force of the ground and is not comfortable in use. As described above, the footrest and the support rod use the combination of the spherical end and the concave arc groove, so that the center of gravity of the human body cannot be efficiently supported, the support process is not smooth, and the tilt is easily tilted. It is not placed upright on the ground, and it has a problem that it is necessary to suppress it by pinching with a cane.
