Abstract

L'invention porte sur une structure de support de pied solide dans laquelle des pieds pliables montés sur la surface inférieure d'une table sont complètement fixés à la fois dans une position dressée et dans une position pliée et dans laquelle, en particulier dans l'état plié, la main d'un utilisateur n'est pas pincée entre la table et un pied en raison du fait que la distance entre la table et les pieds ne change pas. Une première et une seconde surface de came contre lesquelles une butée vient en contact, sont formées sur une plaque de came en une seule pièce avec un pied. Lorsque le pied est dressé sur la surface inférieure d'une table, un élément de contact effectue un contact avec une première section de contact et la butée vient en contact avec la première surface de came, amenant le pied à être fixé dressé sur la surface inférieure de la table. Egalement, lorsque le pied est plié le long de la surface inférieure de la table, l'élément de contact vient en contact avec une seconde section de contact et la butée vient en contact avec la seconde surface de came, amenant le pied à être fixé plié le long de la surface inférieure de la table.
