摘要

傘具是日常生活必備的物品之一，其中具有摺疊功能的傘具最廣為人使用，原因就是收摺體積小而便於攜帶；然而使用傘具之際，常會碰上強風，因此傘具必需具有抗風能力。摺疊傘的收摺機構便是設計的關鍵所在，理想的收摺機構，不僅可以有效縮小傘具收摺後的體積，受到強風吹襲時，亦能有良好的抗翻轉能力。
本研究的目的便是找出由十桿十三接頭構成之摺疊傘的最佳收摺機構構型，首先探討現有的摺疊傘專利文獻，以瞭解摺疊傘作動原理、特性與設計條件；接著針對十桿十三接頭的運動鏈進行機構創新設計與合成，並繪出所有可行之收摺機構圖集，其中單滑件有12個創新構型，2個現有專利，共計14個；而雙滑件有57個創新構型，3個現有專利，共計60個。再使用電腦輔助分析軟體ADAMS建立模型，經模擬後驗證其可行性，最後透過收摺體積以及抗風能力之評比，得到最佳的收摺機構構型。評比結果發現，在單滑件四摺摺疊傘收摺機構中，得到的最佳收摺機構尚未出現於專利中，屬於一種創新機構設計；在雙滑件三摺傘收摺機構中，得到的最佳收摺機構也尚未出現於專利中，也是屬於一種創新機構設計。

Umbrella has become a necessity for daily life. Among all kinds of umbrellas, the folding umbrella is widely used, because it can be folded up for people very convenient to carry it. However, it is very often to come upon the occasion of raining with strong wind. Therefore, the ability of resisting wind of an umbrella also becomes very important at this moment. It is obvious that the design of folding mechanism for a folding umbrella is the most critical part. An ideal folding mechanism should be able to reduce the volume of the umbrella after folding up and have the ability to stand against the wind force as well.
The purpose of this study is to find out the best designs among all different types of folding mechanisms for folding umbrellas with ten-link and thirteen-joint. Firstly, we review the related literature and patents to understand the principle of folding umbrella’s action, characteristics and design requirements. Then, we apply the method of creative mechanism design for the kinematic chains with ten-link and thirteen-joint to obtain all potential mechanisms, and then draw the kinematic diagrams for all feasible folding mechanism. Totally, we obtain 14 feasible folding mechanisms of single slider which includes 12 innovative mechanisms and 2 from patents, and 60 feasible folding mechanisms of double sliders which includes 57 innovative mechanisms and 3 from patents. Then, we build the models of those potential folding mechanisms in ADAMS software, and verify the models by simulation. Finally, obtain the best designs of those folding mechanisms by evaluating and comparing the volume after folding up and the ability to resist the wind.
The results show that the best design of folding mechanism for four-section folding umbrella with single slider is an innovative design which has not been found in the patents, and the best design of folding mechanism for three-section folding umbrella with double slider is also an innovative design which has not been found in the patents too.
