摘要

1.pie of support for photographic studies, essentially characterized because it is constituted from an extensible column, inferiorly associated with a base of support and superiorly to a regulating mechanism of the extensibility of said column, being this formed by a series of articulated plates each other forming deformed parallelograms and arranged according to the faces of a triangular prism, the ends of the plates that form the lower vertices in respective displaceable bushes along as many horizontal bars that, emerging radially from a central core and forming angles of 120º among themselves, determine the support base itself; with the particularity that the regulating mechanism of the extensibility of the column consists mainly of a type of latches operable through a manual control of operation, said mechanism being combined with coil springs arranged around the horizontal bars of the support base. 2.pie of support for photographic studies, according to claim 1, characterized in that the latches of the regulating mechanism are constituted from three bars anchored, each of them, to one of the upper vertices of the column, adopting a horizontal directed position towards the vertical axis of the assembly, said bars being telescopically related to respective tubular portions belonging to a cylindrical core that supports inverted to a tray, which presents in points of its lateral surface windows that are traversed loosely by the corresponding tubular portion, presented each bar, housed in its tubular portion, a wide area with a plurality of notches that, at a constant pitch, appear unitarily by a slot open laterally in its corresponding tubular portion, and whose slot is in alignment with the edge of the windows of the tray. 3.pie of support for photographic studies, according to claims 1 and 2, characterized in that the tray is related to the core with the possibility of making an alternative partial rotation within a horizontal plane that determines the interlocking or release of one of the side edges of your window in the corresponding notch of the bar, being permanently required towards the locking position by traction springs anchored to points of the tray itself and to the tubular portions. 4. Support foot for photographic studio, according to previous claims, characterized in that the drive control of the tray is constituted by the functional combination of two of the tubular portions and two rigid arms to the tray, each tubular portion and its corresponding arm located parallel to each other in order to constitute the corresponding handle. 5. Support foot for photographic studies, according to claim 1, characterized in that the coil springs arranged around the bars of the support base are constituted by a pair of them for each bar, one of which is anchored between the corresponding bushing and the central core, while the other is freely disposed between the other part of the bushing and the end of the bar itself; it being provided that the free ends of such bars involve rolling means for the movement of the assembly, while the upper part has a large tray and a central part constituting the support means for the photographic apparatus. 6.pie of support for photographic studies.
