Patent ID: 8807850

Claim:
A support head for an optical or video-photographic apparatus, comprising: a first body traversed by a first axis (Z) of rotation of the apparatus with respect to a base of the head, a second body coupled in a rotary manner to the first body in order to rotate about the first axis, a third body traversed by a second axis (X) of rotation of the apparatus with respect to a base of the head, this second axis being substantially perpendicular to the first axis, and the third body being coupled in a rotary manner to the second body in order to rotate about this second axis, and locking means able to lock, by a single movement of a control member which may be carried out directly by a user, both the relative rotation of the first and second bodies about the first axis (Z) and the rotation of the second and third bodies about the second axis Y, wherein the locking means comprises a tie-rod extended from the control member along the second axis (X) and displaceable in translation along the second axis, as well as a slider connected to the tie-rod and interposed between the first body and the second body, a surface inclined with respect to both the first and the second axis being defined on the slider and/or the first or the second body, so that when the slider is displaced along the second axis, the slider abuts the first or the second body in correspondence of said inclined surface, so as to displace the first body along the first axis against the second body, to lock the relative rotation of the first body with respect to the second body, and to displace the second body along the second axis against the third body to lock the relative rotation of the second body with respect to the third body.
