Abstract

Est divulgué un dispositif de prévention de coincement de la main, qui peut faire passer un objet cible d'un état fermé à un état ouvert, mais peut empêcher son passage de l'état ouvert à l'état fermé. Le dispositif de prévention de coincement de la main est monté sur un objet cible qui est dans un état fermé lorsqu'une seconde structure est adjacente à une première structure et qui est dans un état ouvert lorsque la seconde structure s'éloigne de la première structure, et comprend : un logement de corps comprenant une partie inférieure et des parties de paroi latérale et ayant une partie ouverte au niveau d'une partie faisant face à une première direction ; une unité de montage pour fixer, à la première ou à la seconde structure, une surface latérale, qui fait face à une seconde direction croisant la première direction, parmi les parties de paroi latérale ; un corps de prévention de coincement de la main inséré dans le logement de corps à travers la partie ouverte de telle sorte que la partie d'extrémité supérieure de celui-ci dans la première direction est exposée par le logement de corps ; et un ensemble ressort disposé entre la partie inférieure et le corps de prévention de coincement de la main. Le corps de prévention de coincement de la main a une élasticité telle que sa partie d'extrémité supérieure dans la première direction peut être renvoyée à la position d'origine après sa rotation au moyen d'une force externe dans le sens de rotation autour d'un axe de rotation, qui croise les première et seconde directions, et la force externe correspondante est supprimée. Par conséquent, la seconde structure peut passer d'un état fermé à un état ouvert, mais ne peut pas se déplacer de l'état ouvert à l'état fermé, et il est ainsi possible d'empêcher les doigts d'être coincés entre les première et seconde structures et d'être blessés.
