Virginie. Door Knob. November 30th , 2017.
Once the door knob was in place, there were further advances to this invention. Soon a lock would be added to a door. That made not only a way to keep the door from accidentally opening, but also a way to intentionally keep people out. That wasn`t enough for some people, who could bust through a simple lock, so there had to be more substantial locks created. Dead bolts were added to really hold a door shut when the person inside wanted it to stay that way. At one point, there were very limited selections if you wanted a door with locks, and even more limited selections if you wanted the additional dead bolt lock that matched the door knob. But things have progressed over the years. Now you can find a door knob in almost any shape or size to do the job you need done.
Interior door knobs are available in four primary styles; privacy, passage, double dummy and single dummy. Privacy and passage knobs turn and operate a latch mechanism - the difference is privacy style knobs have a push pin lock (these are generally used on bathrooms or bedrooms). Single dummy and double dummy knobs do not turn or operate a latch mechanism - a single dummy knob is one knob on the exterior side of the door while a double dummy is a knob on either side of one door. Note: Most double dummy knobs cannot be used on two separate doors.
One important type of lever handle is the keyed lever. This can add security to your home. You need a key to lock and unlock them. Security can be increased with the use of levers with an electronic lock. These are popular with principal users. For internal rooms like a bedroom, privacy levers are crucial. You can lock them from inside and to unlock, you need to use a key in case of an emergency. There are also dummy levers which are not actually used for genuine proposes. You can use them for pulling and decorating.
Many experts agree that the greatest strength of these knobs also happen to be their greatest weakness. Brass is dulled by harmful oils found in our hands; this can give it a great antique look but also means it loses its shine. If this is a problem for you, you may have to reapply varnish to the handle each time this happens. Class door knobs are also rather fashionable these days, their only problem is that they won`t always look great in each house. In fact some people even consider them rather ostentatious in the wrong setting.
When we choose inside door knobs, we have to look properly at the room`s condition. This is important because if we want to use the knobs for our bedroom, we will have to ensure a locking system which could be unlocked from inside only and in the case of emergence, from the outside with a special key. There are privacy door knobs available for this purpose. Other important features for inside knobs are making the room appealing, using the right type of metal, and suitability for the user. This means when we purchase an inside door knob, we will have to purchase it by seeing its matching properties with the room. Metal, like brass, chrome or nickel, used for manufacturing the knob is also very important.
