SUPPORT HEAD FOR AN OPTICAL OR VIDEO-PHOTOGRAPHIC APPARATUS

摘要

A support head comprises a first body (2) including a pin (7) extended along a first axis (Y) of rotation, a second body (3) coupled in a rotary manner to the pin of first body, a third body (4) traversed by a second axis (X) of rotation substantially perpendicular to the first axis and coupled in a rotary manner to the second body and locking means (30) able to lock, by a single movement of a control member (31), both the rotation of the first and second bodies and of the second and third bodies. The locking means comprise a first restraining member (32) able to lock the rotation of the first body with respect to the second body, a second restraining member (40) able to lock the rotation of the second body with respect to the third body, and an actuator member (50) interposed between the control member (31) and the first restraining member (32) and able to command the first restraining member to lock the first and second bodies. The actuator member is further connected to the second restraining member so that the action on the first restraining member causes a reaction on the second restraining member to lock the second and third bodies. The first body is coupled with the second body at the location of the pin (7) and at the location of a widened portion (8) defined on the first body, so that when the first body is displaced against the second body, the first body is encountered by the second body at both the location of the pin and the widened portion.
