<p>An adjustable support head (1) for optical or video/photographic equipment, comprising a joint (5) including a first (3) and a second joint element (18), a body (3) defining the said first joint element, a connection plate (4) for the optical or video/photographic equipment, connected to the said second joint element, so as to enable the said connection plate to be freely adjustable in relation to the said body, locking means (25) mounted on the said body and including a clamping element (26) that can be selectively moved between a first non-operating position in which the clamping element is distanced from the second joint element and a second operating position in which the clamping element is in contact with the second joint element so as to lock the said second joint element in a desired position in relation to the first joint element. The head (1) also comprising adjustable friction means (35) mounted on the body and including at least one slide (36) placed in contact with the second joint element so as to adjust the sliding of the second joint element in relation to the first joint element. The friction means comprise resilient means (37) interposed between the clamping element and the slide to adjust the friction means by moving the clamping element between the first non- operating position and the second operating position.</p> |
