鎖具為日常生活中相當重要的安全裝置，而大多作為門鎖來使用的多點式榫眼鎖，則為住家防護上相當完備的鎖具類型。本研究利用一套系統化的方法，設計多點式榫眼鎖的新型機構。首先介紹機械鎖具的分類與優缺點，並探討榫眼鎖的定義與演變。接著針對多點式榫眼鎖之構造，依作動方式與使用功能將其分為活閂鎖、靜閂鎖、靜活閂鎖、及連動機構等四個子機構，再分別歸納出各個子機構的拓樸構造特性及設計需求與限制。再者，根據創意性機構設計法，進行新型多點式榫眼鎖的概念設計，並得到各子機構的設計圖譜。從所合成機構之設計圖譜中，評估與選取較適當之機構構造，再依尺寸規格設計出可行的鎖具。最後，經由電腦動畫模擬及實作模型，驗證出所設計的新型多點式榫眼鎖，的確能達成預期的作動需求。本研究成果可為業者設計多點式榫眼鎖的設計參考，並可作為榫眼鎖機構特性研究的依據。

Locks are important safety devices in our daily lives. The purpose of this study is to design new mechanisms of multipoint mortise locks based on a systematic approach. Firstly, the classification and advantages of mechanical locks are introduced, and the definitions and the development of mortise locks are described. Then, the multipoint mortise locks are decomposed into four sub-parts by the different functions, including the latch bolt lock, the dead bolt lock, the dead-latch bolt lock, and the connecting mechanism. The four sub-parts are further analyzed to conclude their structural characteristics as well as design requirements and constraints. Based on Yan’s creative mechanism design methodology, the concepts and the atlas of designs are synthesized systematically. One feasible mechanism is further chosen for detail design. Finally, a computer program for simulation is developed and prototypes are built for verifying the design results. The results of this study provide a valuable reference for designing multipoint mortise locks and for the analysis of mechanism characteristics of mortise locks.
