多腳助行拐杖之改良結構Improved structure of multi-foot walking crutches

本創作係關於一種多腳助行拐杖之改良結構，尤指一種適用於輔助年長者或病患行走之多腳助行拐杖之改良結構。This creation is about an improved structure of a multi-legged walking stick, especially an improved structure for a walking aid for a senior or a patient walking.

多腳助行拐杖係由拐杖慢慢轉變而成，當年長者或病患之行動力不足以單靠拐杖支撐，卻尚未嚴重到喪失下肢功能時，可利用多腳助行拐杖幫助使用者行走並可作為復健器材使用，藉以將部分倚靠之力量轉移到多腳助行拐杖上，而減輕下半身的負擔，同時保持行走時之身體平衡。The multi-legged walking stick is slowly transformed from a cane. When the senior or the patient's mobility is not enough to be supported by a cane, but it is not serious enough to lose the function of the lower limb, the multi-foot walking can be used to help the user walk and It can be used as a rehabilitation device to transfer part of the leaning force to the multi-legged walking stick, reducing the burden on the lower body while maintaining the balance of the body while walking.

然而，由於使用者多半是年長者或病患，其手部力量可能也不足以長時間重複抬起並放下該助行拐杖，故需藉由加裝輔助輪子，將手部抬升助行拐杖之施力，轉化為向前之推力，有效減輕手部的負擔。不過，具有輪子之多腳助行拐杖將會大幅增加意外的風險，故針對安全性的顧慮，勢必需設置有完善的前進與煞車機制，使用者方可安心使用。However, since the user is mostly an elderly person or a patient, the hand strength may not be enough to repeatedly lift and lower the walking aid for a long time. Therefore, it is necessary to lift the hand to assist the walking stick by adding an auxiliary wheel. The force is transformed into a forward thrust, effectively reducing the burden on the hand. However, the multi-footed walking stick with wheels will greatly increase the risk of accidents. Therefore, for safety concerns, it is necessary to have a perfect forward and brake mechanism for users to use with peace of mind.
