Door Knob Or Doorbell?
Dieter Volkers's designs incorporate soft materials that make his products multi-functional and captivating.
The Doorclaxon by Dutch designer Dieter Volkers is a doorknob that can also be used as a doorbell. Instead of the usual metal knob, Vilkers has incorporated a soft material that attaches to the knob’s extension to make it an improvised air horn. Clever design.
