“I needed an easier way to find my way around at night without bumping into things or fumbling for the doorknob,” said an inventor from Orlando. “This inspired me to come up with this convenient idea. It also keeps doorknobs from damaging walls when the door opens.”
He developed the patent pending REFLECTIVE DOOR KNOB to make it easier to get around the house at night or in the dark. This keeps the user from inadvertently bumping into walls or other obstacles.
The design also safeguards the adjoining wall from damage caused by a door opening and striking it. The invention provides added peace of mind. It is adaptable for use with any door. Additionally, the doorknob features a highly visible design.
The original design was submitted to the Orlando sales office of InventHelp. It is currently available for licensing or sale to manufacturers or marketers. For more information, write Dept. 18-ORD-2707, InventHelp, 217 Ninth Street, Pittsburgh, PA 15222, or call (412) 288-1300 ext. 1368.

“Although it is difficult to provide an exact date of when door knobs first came into use, the first documentation of the invention of a door knob was in 1878,” according to Handsome Handles.
“The U.S. Patent Office received a submission made for improvements on a door-closing device by an African-American inventor named Osbourn Dorsey. Door knobs and door handles are now a vital part of modern doors!”

“Before Dorsey’s invention people closed and secured doors in a variety of ways,” according to Reference.com.
“Many people used some type of latch to keep doors closed, whereas others used leather straps as handles.
“Even after the doorknob was invented it took years for people to embrace them fully and begin installing them on the doors in their homes.”
