Abstract

L'invention concerne un dispositif de fixation permettant une fixation libérable d'un article sur un support, comprenant une plaque d'aspiration, sur laquelle une bague d'étanchéité est placée de manière à être installée sur le support, et une pompe à vide électrique, grâce à laquelle l'interstice, à rendre étanche de la bague d'étanchéité, situé entre la plaque d'aspiration et le support est soumis à une dépression. L'objectif de l'invention est de produire un dispositif de fixation pouvant fonctionner indépendamment d'une tension du secteur et pouvant être actionné simplement. A cet effet, la plaque d'aspiration est intégrée à un logement, qui comprend la pompe à vide, une batterie, ainsi qu'un organe de commutation électrique permettant de brancher ou de débrancher la pompe à vide. De plus, un dispositif de récupération des saletés dues au perçage est intégré dans le logement du dispositif de fixation.
