When were door handles invented?

In older days, only the rich could afford locks with keys, and this was before the invention of door handles. The inner doors were nailed together to allow the type of wrought iron latch or a cott one to open and close the door. The reign of Louis XIV saw the use of decorated and gilded doorknobs. These products were created to suit his opulent lifestyle. Similarly, crude concealed mortice was also invented to get the best and most suitable crafted doorknobs.
