Types Of Door Locks On Sale For Securing Our Homes, Keeping Out Intruders, And Guarding Our Items Of Value
The first elementary tumbler style door lock was created in around two thousand BC, was fabricated out of wood and probably didn't do much of a job for the more determined burglar, but it represented a start. There wasn't a lot of choice for someone owning something valuable, but to make sure it was hidden, or lock it inside a house or some kind of safe.
Sadly, this fundamental state of affairs hasn't really changed - even though most folk don't have diamonds in the house, the total contents in the average home runs into thousands of dollars, without taking into account those irreplaceable items with sentimental value. There's no getting away from it - a great quality door lock is necessary in the modern world, unless we live in one of those magical places where the doors are never locked! If you have to fit locks to new doors, then it's the perfect opportunity to get exactly the right thing. Many types of door locks can be used for home security.
Nowadays its very advisable to be cautious when responding to a knock at your door, regardless of the time of day or night - remember that the majority of unlawful entries to someone's house is by a casual thief. If the home owner is frail, then this is one of the chances they are looking for and will likely respond to.
A natural response to this possibility is to have a door chain fitted, but will this be effective? The usual quality door chain is equipped with inadequate short screws to fasten the fittings to the inside of a wood door and frame. These kind of fixings are easily ripped out by a person willing to use force to break in. By the bye, the best lock in the world is useless if the door it is screwed to isn't strong enough to keep out a thief.
For possessions that need less security, or often left in full view, like a bicycle attached to a railing, for example, or a suitcase on a train, some types of combination locks may be used. This variety of lock is considered the least secure, and various measures have been taken to try and improve it's security. In in it's base form, a mechanical version may consist of 3 or 4 wheels with numbers inscribed on their outer rims.
When the correct numbers are shown in a row, then the internal mechanism unlatches a bolt which can be easily extracted. The cheapest of these are rather easily opened, due to internal imperfections in the moving parts. It's possible to feel the slight 'tick' when the wheel is in the correct place, and so on for the remainder of the wheels.
