Title
(EN) CAMERA LEVELING HEAD
(FR) TETE DE MISE A NIVEAU DE CAMERA
Abstract
(EN) A leveling head (25) for a camera has four jacking screws (90) attached to a base plate (70). A ring (122) is pivotably attached to a hub (100) on the base plate (70). A top plate (130) is pivotably attached to the ring (122) and supported on the jacking screws (90). The top plate (130) can pivot along two perpendicular axes relative to the base plate (70), to provide a level mounting surface for a camera. A spring (112, 114) on the base plate (70) pushes the top plate (130) upwardly, to partially counterbalance the weight of the camera, to reduce the turning force needed on the jacking screws (90).
(FR) L'invention concerne une tête de mise à niveau (25) de caméra comportant quatre vis de calage (90) fixées à une plaque de base (70). Un anneau (122) est fixé pivotant à un moyeu (100) sur la plaque de base (70). Une plaque supérieure (130) est fixée pivotante à l'anneau (122), reposant sur les vis de calage (90). La plaque supérieure (130) peut pivoter selon deux axes perpendiculaires par rapport à la plaque de base (70), afin de présenter une surface de montage stabilisée pour la caméra. Un ressort (112, 114) sur la plaque de base (70) pousse la plaque supérieure (130) vers le haut, de manière à contrebalancer partiellement le poids de la caméra, réduisant ainsi la force de torsion qui doit être exercée sur les vis de calage (90).
