Garage Door. Saturday , December 09th , 2017 - 05:56:44 AM
In 1912, an architect created "a new type of outbuilding". The garage, which comes from the French word garer- to shelter or protect, was invented. The first garage door was essentially a barn door. It was a double door attached to the garage with strap hinges that opened outward. They had the appearance of a basic shed and were subjected to heavy wear and tear. The hinges got rusty and squeaked and the screws would bend and eventually fall out. Snow made it difficult to open and close the doors as well.
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. These doors can be chain driven either manually, or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently, and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door, as the weight of these type of doors is normally much greater than an overhead door.
The Bigger the Better - In the '70s, a large number of American homes had one-car garages. After three decades, the trend shifted, making room for two-car garages. Now, garages keep getting bigger to accommodate larger vehicles like SUVs, pickups, and RVs. Garages that are large enough for four to five vehicles seem to be the minimal standard in high-end villages. Even real estate agents will affirm that big garages are great assets with good selling point.
