ABSTRACT:
A resilient door knob utilizes both a spring-loaded internal housing and a resilient foam knob so that the doorknob absorbs shock when the door is swung against a wall, or someone strikes the doorknob. Another important feature is that the knob comes in sets of knobs of different colors or configurations such that one knob can be pulled off (or slit of if necessary) of the shaft housing and replaced with another one of a different color in the event, for example, the room is re-painted.
