Pelle-bêche avec un pied articulé pour minimiser l'effort, photographiée à Meudon Bellevue le 23 avril 1920. Assortie d’une pédale, d’une came et d’un levier, elle vise à alléger l’effort de jardinage. Lorsque le levier est actionné, la came tourne, ce qui fait se déverser la terre sur le côté. Office national des recherches scientifiques et industrielles et des inventions (ONRSII). Extrait du livre Inventions 1915-1939 de Luce Lebart.

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
