Pin for use in cylinder lock i.e. standard double cylinder lock, of e.g. flat door, tracks all movements of inserted pins and facilitates reading-out from cylinder lock, where pin controls contact disc

摘要

The pin (5) tracks all movements of inserted pins (3, 4) and facilitates reading-out from a cylinder lock i.e. standard double cylinder lock, where pin (5) controls a contact disc (7) and multiple contact surfaces (8) bridges on a contact plate (10) such that a movement condition of the pin (5) is indicated and transmitted. A small casing (9) is fastened with an opto-electronic markable surface on the pin (5). The contact plate is restored by an opto-electronic component. An independent claim is also included for a fun greeting and farewell text and voice alarm, optical and mute messages and registrations provided-out from a cylinder lock telemetrically through cable or radio.
