Except for those dastardly swinging doors which I never liked and think are one of the world’s most dangerous inventions, every door needs something to grab on to in order to be opened and closed. It’s that round or oval device that you rarely think about, even though you wrap your hand around it 100 times or more a day.
But especially after I read recently that there are about two million germs per square inch attached to the average doorknob and the experience of showing a buyer client too many houses during flu season, I became very aware of every doorknob I touched and really started to scrub my hands down many times during the day.
The doorknob is an ingenious little device actually. The traditional knob itself has a bolt or spindle running through it that sits just above a cylinder, to which the spindle is connected. Turning the knob pulls the cylinder in the direction of the turn. The end of the cylinder is a latch that protrudes into a space that is carved out of the door frame and prevents the door from being opened if the knob is not turned. The mechanism is a little more complex than I’m describing it here, but I’ll leave further understanding to the technicians among us.
