Door handles are the knobs and handles that are used to open a door. These are found on both internal and exterior doors. Depending on the type of door, they may come in a variety of styles and designs. The most common styles are lever handles and latch handles. They are also available in a number of different finishes.
Historically, door handles have been developed in different regions, depending on the local design. For example, in central Europe, elaborate wrought-iron lever handles are found on doors in 18th century houses. While in England, simple round or oval knobs are used. Throughout the nineteenth and twentieth centuries, architects began to experiment with door handle design.
Early door handles were made from leather straps, wood, or iron. Eventually, they were replaced by the more functional and decorative door knobs that we now know. Doors were first used in ancient Egypt to shelter and protect people from the elements. In the modern era, they are now a vital part of interior design. Their designs have evolved over the years, with the most notable examples being those designed by Antoni Gaudi for the Casa Batllo in Barcelona.
Door knobs have many benefits, including their ability to prevent the spread of germs. Some models have built-in alarms to warn you of unauthorized attempts to enter your home. Others use wireless technology to allow you to lock your doors without using a key. There are also locks that can be installed on the inside or outside of your doors, providing greater security and privacy.
Lever-operated door handles are easier to operate than their knob counterparts. These are also more convenient for elderly people. Because the lever does not require a strong grip, they are easier to operate with wet hands.
Many door knobs have an indicator light, which allows you to know when your handle is in use. If you have a service animal, you can purchase a handle that is reversible.
Some newer designs include foot-operated and forearm-operated handles. Some door handles are even available with antimicrobial coatings, which are designed to protect the finish from dust, dirt, and bacteria. A few doors have a keyed cylinder that requires a key to unlock, making them a great choice for bedrooms and closets.
Door handles are available in a variety of different materials, with the most popular being Copper, Brass, and Nickel. These metals are highly durable, and rustproof. Stainless steel is another option, and is a great choice for a modern look. Other popular door hardware finishes are Silver, Brushed Nickel, and Matte Black.
Door handles are often manufactured to fit standardized door latching mechanisms. The backset, or distance from the edge of the door to the center of the handle, varies from a few inches to the exact center of the door. This is a measure of the cost of manufacture and the aesthetics of the design.
Most household door handles have a screw-style axle. Some handles have a sliding handle on the spindle. Others are attached through set screws.
