The History of Locking Devices

Locks are used all over the world to secure physical belongings and sensitive documents, with a wide range of different mechanical and electronic technologies used. locking devices (Schliessanlagen) have been used for thousands of years, with evidence of their use in a number of different cultures around the world. There is a universal need for people to protect and secure their belongings, without having to resort to constantly guarding them or hiding them. Some of the earliest solutions included the use of various kinds of knots, which were often used as a way to detect intrusion and hamper intrusion attempts. However, the earliest locks that were similar to those of today have been found in a number of places, with evidence of their use in ancient Egyptian, ancient Greek, and ancient Roman cultures.

The earliest locks featured wooden locks and keys, and were in use as early as 4,000 years ago in Assyria. The first known lock used a pin lock mechanism, with the actual lock strung on a rope from a hole in a door. This type of basic cylinder lock is still in use today in certain places, with many people in Puerto Rico still using this system. Locking mechanisms have developed a lot since the early days however, with many advances is steel work and locking mechanisms leading to more secure and reliable mechanisms. Some of the many locks which have been developed over the ages include the pin tumbler lock, the wafer tumbler lock, the lever lock, the disc tumbler lock, dimple locks, and a huge variety of electronic locks in the last couple of decades.

Many of the advances in the evolution of locking mechanisms can be attributed to famous locksmiths, many of whom developed completely new systems for their time. For example, Robert Barron patented the first double acting tumbler lock in 1778, which was the first major improvement to locks in a long time. James Sargent was another famous locksmith who made his mark on the development of locks, when he invented the combination lock in 1857. There has been a number of improvements to lock technology over the last few centuries, mostly due to increased precision and better access to new materials and techniques of production. In the modern age, many of the advances have been based around the innovation of electronic locking devices, and especially with their integration with electronic security systems.
