Abstract: The tripod includes a spider for the articulation of the legs and a support mounted in the spider with a first seat coaxial with the principal axis of the tripod and a second seat with an axis substantially perpendicular to the first seat so that a column of the tripod can be housed alternatively and removably either in the first seat or in the second seat.

Abstract: A stand for photographic/optical and cinematographic equipment comprises a central column and a tripod base for the column including three legs and respective arms for connecting the legs to the column. The base comprises a first and a second articulation element slidable on and fixed to the column, respectively, with the legs articulated to the first articulation element about articulation axes substantially perpendicular to radii of the column. The connecting arms have their opposite ends articulated, respectively, to an intermediate portion of the corresponding leg and to the second articulation element, and each leg is movable from an inoperative position in which it is brought, with the corresponding connecting arm, close to the column, to an operative position in which it is opened out away from the column.

Abstract: An extendable rod comprises a bracelet which is releasably lockable on a rod-shaped element of the rod, a depression which is formed in the bracelet and which can accommodate an end portion of a lever pivoted on the bracelet in such a manner as to permit the relative sliding of the bracelet on the rod-shaped element, and a surface which is raised with respect to the depression and which is engaged by the end portion of the lever in order to tighten the bracelet on the rod-shaped element.

Abstract: An extendible rod comprises two rod-shaped elements slidable telescopically inside each other, and an expander device for locking the rod-shaped elements against sliding in an extended position of the rod, wherein the expander device comprises a linkage acting between first and second constraint members, being each associated with a respective one of the rod-shaped elements to drive them through a stroke of mutual separation, and wherein the length of that stroke may be adjusted.

Abstract: An adjustable stand with a telescopic stem comprises a locking device for fixing the stem elements to one another firmly, the locking device including a collar which is connected to the first stem element and is automatically clamped onto the second element as a result of the load bearing on the second stem element.
