Door Lock Technology Through The Years

The safety and security of our household is always the first thing that we look into. Our concern for safety factors is not only limited to our family members but with properties as well. We go through all the measures and keep them away from danger. We look for a relatively safe place to stay in and even go to the extent of transferring around until we feel that we found it. We place child proof devices and alarm systems just in case. The most basic of these security devices is a door lock.

The rope was the earliest locking device used. The thief knot got it's name because it was used to notice thieves and the Gordian knot was used to discourage them. We still use this tactic to shut a door that does not have any locking mechanism. History is questionable as to when the lock started. However there are some evidences that the Egyptians, Greek and also the Romans used wooden locks and keys some 4,000 years back. The very first known door lock with a key is known as a pin lock or pin tumbler lock. This is also the most widespread lock. The old pin tumbler lock was made of wood and rope and to this day this sort of wooden lock mechanism is still being used in Puerto Rico.

Because of weakness in the old design the volume of pins was extended as well as the orientation of the pins was changed to boost security. The development that was made to the ancient design became the established rules of pin locks in the present. Another advancement came for the pin lock; the wooden pins with bronze or iron. This new design was then patented in 1805. A father and son locksmith, Linus Yale Sr and Jr, enhanced and refined the patented metal pin lock design The lock design of Yale's is what is recognizable today. Wafer tumbler locks are another style of door lock. Wafer locks are generally used in automobile doors and cabinets. Still another commonly used type of lock is the lever lock. Safes and prison doors are normally made from these kinds of locks.

There are also mechanical and electromechanical locks. Currently there are multiple variants of the different varieties of locks. Among the list of variations we have the panic bars, lock sets, lock boxes, deadbolts, mortise locks, bump-proof locks to name a few These variations are what are presently used in structures and houses. Some of the types of these lock for the doors have been incorporated with advanced technology to further increase the safety measures. Emergency exits doors are installed with one of these safety measures usually alarmed panic bars. This is also already utilized in our car door alarms.

With the continued innovations of our inventors we know for sure that the door lock technology that we currently have will still be improved allowing us to sleep better knowing that we are safe and secure in our homes. We should all remember that.
