Door Lock Advancement From Rope to Metal

The safety and security of our household is always the very first thing that we look into. Our concern for safety is not only restricted to our house members but with residences as well. We go through all the procedures and keep them away from harm. We look for a relatively safe place in which to stay and even go to the extent of relocating around until we feel that we found it. As an additional comfort and safety measure we place child proof and alarm systems. The door lock is the most primitive and yet helpful security device available.

The rope was the primary locking device used. This would be knotted to detect, hence the thief knot, or hamper, like the Gordian knot. We still use this method to shut a door without any fastener. It is still unclear as to location that the first lock was created. However there are a few proofs that the Egyptians, Greek and also the Romans used wooden locks and keys some 4,000 years back. The pin lock is said to be the first lock design created. This design is the commonly used lock even today. The ancient pin lock style used wood and rope and til today homes in Puerto Rico are still using this type of technology.

To enhance the security level of the old design of the pin lock the inclination of the pins had to be changed and the number of pins is increased. These changes were then the established concepts of the present day pin tumbler locks. Another development came for the pin lock; the wooden pins with bronze or iron. It was this metal design that got patented in 1805. A father and son locksmith, Linus Yale Sr and Jr, improved and refined the patented metal pin lock design The lock design of Yale's is what is recognizable today. Yet another kind of door lock certainly is the wafer tumbler lock. Wafer locks are usually used in automobile doors and cabinets. Lever locks are the third most commonly used. Safes and prison doors are generally made from these types of locks.

Additionally, there are mechanical and electromechanical locks. Presently there are multitudes of variations of the different types of locks. A number of variations we have the panic bars, lock sets, lock boxes, deadbolts, mortise locks, bump-proof locks to name a few Presently any of these variation types are located in buildings and houses. Some of the types of these lock for the doors have been incorporated with advanced technology to further improve the security features. Emergency exits doors are installed with one of these safety measures usually alarmed panic bars. This is also already being used 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.
