This story was published in the "Far North Dallas Advocate" magazine in the March 2011 issue. It had a happy ending but how easily it could have turned tragic. What if the wife had not awakened during the night? What if the husband did not have a rifle? What if the robber struggled with the husband and took his rifle away? A simple robbery could have easily turned into a homicide. Now ask yourself this: "What if that had been your home and your family that were threatened?"
Dallas Police Liutenant Barry Payne of the North Central Patrol Division was quoted as saying: "Citizens must realize when they leave a garage door opener in their car in their driveway it is like leaving a key to their house outside where everyone will know where it is. The solution is simple: Park in the garage or dont leave a garage door opener in the car in the driveway. I cant say it any clearer than that. Actually this home invasion could have been avoided in three different ways: the family could have parked their car in the garage they could have parked outside of the garage yet removed the garage door opener from the vehicle OR they could have securely locked the door going from the garage to the home.
In contrast to an overhead type of garage door be it sectional or single panel roll up doors have a totally different type of operating system. When these doors are used they can be concealed in an overhead or under mounted trough. These doors operate similarly to a roll top desk door except for how they are stored when not in the closed position. They normally coil as they are retracted and require significant gear trains to reduce the effort required to move these doors up and down into position. Often the forces needed to move these roll up doors require a reduction type of transmission that allows a very heavy door to be operated effortlessly.
With a torsion type of spring the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation the complete loading of the torsion spring is controlled by the garage installer and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained unqualified individuals have attempted to install or service this type of spring.
