Abstract

L'invention concerne une tête de trépied (1) comprenant un joint à rotule disposé dans un boîtier de tête de trépied (12). Sur le boîtier de tête de trépied (12) est disposé un dispositif de blocage (19) commutable qui peut passer d'une position de libération à une position de blocage en vue d'immobiliser un mouvement de pivotement du joint à rotule (11) autour d'au moins un axe de pivotement. Le dispositif de blocage (19) possède une goupille de blocage (193), montée coulissante dans un trou traversant équatorial (11d) du joint à rotule (11), qui peut être engagée dans une position de blocage par une touche de blocage (191) disposée sur le boîtier de tête de trépied (12).
