Door Handle

everyday invention · how things work · design

Opens and closes. Door handles are found on nearly every door you encounter, from your bedroom to cars to kitchen cupboards. They give you a safe grip to pull or push the door open and closed.

Locks things up. Many door handles have special latching or locking mechanisms built right into them, which means they can both open the door and keep it secure when you lock it.

Comes in many styles. Door handles come in tons of different designs depending on where they're used, from simple knobs on your closet to fancy handles on fancy doors to special handles on car doors.

Works everywhere. You'll find door handles on residential homes, office buildings, stores, vehicles, and cupboards. They're one of the most common inventions we use every single day without thinking about it.

Connects to locks. Most door handles for homes and businesses are designed to work with standardised locking mechanisms, which means they fit together perfectly like puzzle pieces.
