How Doorknobs Work

The mechanics of doorknobs are more complex than most people imagine. The way a doorknob works is by having a stationary arm that rotates a lever back and forth, allowing doors or windows to be opened. Although this sounds simple enough, there are a few things you need to know before you try it for yourself.

If you have a garage in your house, then chances are that you have a doorknob that works with your garage door. The mechanics of how doorknobs work exactly the same way, even if the door you are using has a different mechanism. There are two parts that make up a doorknob: the head of the knob, and the stationary arm. The head of the knob is what you use to turn the arm, and is usually either a lever or a push button. When you are learning how doorknobs work, you will see that both of these pieces move, making the actual turning motion necessary for opening or closing your doors or windows.

Doorknobs that are meant for sliding doors will usually have a series of levers attached to the track, which allow the door to slide on a track, and determine how the door handle opens. Sliding doorknobs usually use a track similar to the track on a garage door; however, it will usually have additional handrails on both sides of the doorknob. These extra handrails are used to control whether the door will roll up or down, and to keep the door handle from accidentally moving when you are using the doorknob to open and close your garage door. The actual lever used to turn the arm on a sliding door is not that dissimilar to a regular lever, as it is usually shaped like a regular lever, with a slot on the end for a ratchet mechanism to hold the door closed.

One of the most popular styles of doorknobs, due to the number of styles available today, is the up-and-down Venetian style. This style has two separate tracks, with one track running along the top edge of the door itself, while the other track runs along the bottom edge of the door. Each side of the door handle has a bar on both sides, which allows the door to be opened by pulling the handle down. Doors in this style normally have a round Venetian blind above the space between the two tracks.

You will notice that some modern day styles of door knobs use a single lever to operate both the door and the handle. These lever-operated door knobs are great if you are looking for a knob that is more decorative, and that won’t require you to turn your arm. However, these door knobs are also very hard to turn by hand, since turning the arm requires bending your wrist. Another advantage of a single Lever arm is that it is more secure and does not require any moving parts, unlike the lever-operated door handles.

The next time you plan to replace your doorknobs, or look into buying new ones for your home, I encourage you to take a moment to understand how doorknobs work. The earlier you master the mechanics of how doorknobs work, the easier it will be for you to maintain your doorknobs in the future. If you mess up on the installation of a doorknob, for example, it may be difficult or impossible to get it fixed. By learning how doorknobs work, you can prevent this type of situation from ever happening.
