KEY SET WITH ANTI-THEFT MECHANISM
PROBLEM TO BE SOLVED: To provide a highly operable key set with an anti-theft mechanism.SOLUTION: A key set A with an anti-theft mechanism comprises a cylinder device 20 that includes a cylinder 22 having a key insertion hole 22a and a shutter part 23, and a key 30. The shutter part 23 includes: a shutter 24 disposed rotatably on a side with an operated side surface 22b of the cylinder 22, the shutter having a key penetration hole 24a of which a hole shape coincides with that of the key insertion hole 22a and being communicated with the key insertion hole; a cover material 26 disposed opposite the shutter 24; and a lock part comprising a storage recess 24b formed on the shutter 24, a magnet 27 and a coil spring 27a disposed in the storage recess, and an engaging recess 26c formed on the cover material 26. The key 30 includes a magnet 36 disposed on a side with an operating surface of a key body 31 for energizing the magnet 27 toward an inner side of the storage recess 24b, when coming in close to the magnet 27, and a main key 34 that may be advanced and withdrawn from the operating surface of the key body 31.SELECTED DRAWING: Figure 4
【課題】 操作性が優れた盗難防止機構付きキーセットを提供すること。【解決手段】 キー挿入穴２２ａを有するシリンダー２２とシャッター部２３を備えたシリンダー装置２０と、鍵３０で盗難防止機構付きキーセットＡを構成した。シャッター部２３に、シリンダー２２の被操作側面２２ｂ側に回転可能に配置されキー挿入穴２２ａに穴形状を一致させて連通できるキー挿通穴２４ａを有するシャッター２４と、シャッター２４に対向して配置されたカバー部材２６と、シャッター２４に設けられた収容凹部２４ｂと、その内部に配置された磁石２７とコイルバネ２７ａおよびカバー部材２６に設けられた係合凹部２６ｃとからなるロック部を設けた。鍵３０に、鍵本体３１の操作面側に設けられ磁石２７に接近したときに磁石２７を収容凹部２４ｂの奥側に付勢する磁石３６と、鍵本体３１の操作面から進退可能なメインキー３４とを設けた。【選択図】 図４
