Disc anniversary

by Mark Rowe

It’s 110 years since a Finnish invention that sparked a revolution in the lock industry – founder Emil Henriksson’s disc cylinder operated lock. A precision mechanic, Henrikkson recognised that the principle of the rotating detainer discs inside a cash register could be applied to locks. His idea for a secure and durable lock was patented in 1919, when the now globally recognised Abloy trademark was also registered.

Thanks to its disc design, the lock was virtually unpickable. This led to Abloy becoming the market leader in 1930s Finland and growing to a global scale. The 1960’s and 1970’s saw the integration of electromechanical technology into Henrickkson’s mechanical lock.

In 1994, Abloy merged with ASSA to form the ASSA ABLOY group. In the last decade, Abloy has developed access control systems such as PROTEC2, CLIQ, pictured, and CLIQ Connect.

Abloy’s range of products take in mechanical and electric locks, as well as access control systems for applications including utilities, telecoms and banking. Visit www.abloy.co.uk.
