Most people do not remember when overhead doors for garages did not exist. There actually was a time when that was true, but when they were invented, a wonderful convenience was placed into our society. It was one of those things where people would say that they wished they had thought of that, but in has now become a way of life.
It is hard for most of us however, to understand what it would be like, not to have the convenience of overhead doors that automatically open at the push of a button. Think of how many times you have pulled up to your garage in a driving rainstorm, only to be glad that you can simply press the button to open the door and drive right into the garage. This is especially important if you are a housewife with a car full of groceries, and several young children along with you in the car.
The automatic garage doors are also a very significant safety feature for a home. They are difficult, if not impossible for an intruder to break into. A garage door that is not set up as an automatic garage door, is much easier to foil, because it is not attached to any other mechanism than a lock, perhaps, which can easily be compromised. It is also a very nice feeling to be able to drive into a secure garage and have the door close automatically behind, and know that any hazardous situations are securely outside the door as it closes.
The first automatic garage door was invented in 1926 and the trend has grown ever since then. Everyone enjoys convenience, especially when coupled the safety features that came along with it. Standard garage doors that are not automated are very heavy to lift, especially for the ladies.
Most overhead doors that are used today operate on the principle of an electric motor being the main device that drives the upward and downward movement of the door. The motor is installed at the top the door in such a way as to pull and push the door in the direction in which it is to go. The attachment is fixed and is driven by series of levers that travel up and down with the door as it is driven by the motor. The motor is plugged into a socket in the ceiling of the garage.
These doors are items that our society would be much worse off, if they had not been invented and placed into practical use in our society.
