Foot-operated door opener to eliminate the door handle as a source of contamination

摘要

>Aim: As door handles represent a transmission route for viruses and micro-organisms, a door opening and closing mechanism should be developed without manual operation.>Method: To solve the problem, a device for opening the door with the help of a foot pedal was built into the door leaf.>Results: The design enables mechanical opening of the door with a foot pedal without manual operation. Subsequently, the door closes with the help of a mechanical locking mechanism.>Discussion: The foot-operated door opener constitutes an additional option to the door handle. Together with the equipment of a soft closing mechanism, it is possible to prevent noise emanating from the door latch impinging on the door frame. Using this construction, the door handle as a transmission vector is eliminated. In addition, the transport of goods held with two hands simultaneously is facilitated.>Conclusion: With a foot-operated door opener instead of the traditional manual door handle, it is possible to open doors with a foot pedal. This prevents contamination of door handles with pathogens.
