A support tripod (1) for video-photographic equipment, comprising a spider (2), a column (8) provided with hooking means (9) for a piece of video-photographic equipment slidable along a sliding axis (Z) inside an aperture (7) defined by said spider (2), a plurality of legs (4) hinged at a hinging end (4a) to said spider (2) to open/close the tripod (1), each leg (4) having a body extending mainly along a longitudinal axis (Y) and being rotatable about a hinging axis (X) substantially perpendicular to said longitudinal axis (Y) and extending through the spider (2) to be moved between a closed configuration (W, W′) in which the legs (4) are arranged almost parallel with the sliding axis (Z) and at least one operating configuration (K, J) in which the legs are inclined relative to the sliding axis (Z) at a desired opening angle (α1, α2), each leg (4) being provided with an adjusting device (30) in order to adjust the angular position of the leg (4) up to a maximum opening angle (α1, α2) relative to said sliding axis (Z), wherein said adjusting device (30) comprises an adjusting head (31) provided at the first hinging end (4a) actuatable in rotation about the longitudinal axis (Y) of the leg (4) and provided with translation means (40) cooperating with corresponding translation counter-means (41) defined on the leg (4) to translate the adjusting head (31) along the longitudinal axis (Y) relative to the leg (4), following the rotation about the longitudinal axis (Y), to vary the length of the leg (4) and the interference between the hinging end (4a) and the spider (2) to allow variation of the maximum opening angle (α1, α2) of the leg (4). |
