劉立祥 欉致賢 / Angle lock

ANGLE LOCK is a brand new type of bicycle lock. People usually need to carry a

bicycle lock whenever they ride a bicycle. Such a heavy lock would be troublesome,

either to carry it or use it.

角鎖是一個全新的腳踏車鎖設計。對於腳踏車騎士來說，最重要的就是腳踏車的防盜問題。

通常騎士都要攜帶厚重且操作複雜的腳踏車鎖出門，而大家卻因為習以為常而忽略了這個問

題。而角鎖解決了這樣的問題。

The concept, ANGLE LOCK, combines stem switch and number lock which have

been installed in the bicycle frame in advance. Riders can easily lock the bicycle

by turn on the number lock to fix the stem at certain degree so that it can’t turn

left or right anymore. Therefore, the bicycle can’t move as usual. If someone wa-

nts to break ANGLE LOCK to make the bicycle stem free to turn, he has to break

the frame of the bicycle. 

角鎖結合了密碼鎖以及龍頭制動裝置，事先安裝在腳踏車架中。應用鎖住龍頭就無法行使的

 概念，當騎士將龍頭轉至特定的角度並啓動密碼鎖，即可輕鬆簡單的鎖住腳踏車。若竊賊想

破壞角鎖，他必須破壞整個腳踏車車架結構。

[ISSUE]

There are many kinds of bicycle locks. The common point is that riders need to car-

ry a heavy lock additionally, which is troublesome. Also, it may let your hands dirty

while using the lock.

近年來單車休閒及通勤盛行，扮演生活中重要的角色，而如何防止單車失竊降低失竊率，成為

一個重要的議題。市面上各式各樣的腳踏車鎖的問題點在於竊賊可以輕易破壞並且騎士需要攜

帶厚重的車鎖出門，在使用時更會汙染雙手，是很不方便的。
