A tripod particularly for use in optical and photographic applications. The tripod includes a spider having a main axis, at least three legs converging in the spider and articulated upon the spider, and a support in the spider for supporting a column. Provided in the support are components for placing the column and for removably locking the column in at least two positions in which the axis of the column is angularly inclined with respect to the main axis of the spider.

1. A tripod comprising:a spider having a main axis;at least three legs converging in said spider and articulated thereon;a column having an axis;a support in said spider supporting said column, said support including means for placing the column and means for removably locking said column in at least two positions in which the axis of the column is angularly inclined with respect to the main axis of the spider, said support mounted rotatable in said spider about said main axis, anddisposed between said support and said spider, means for blocking the rotation of the support about said main axis, and said means for placing the column is incorporated in said means for blocking the rotation of said support. 2. The tripod according to claim 1, wherein said support comprises a first part and a second part respectively rigidly connectable to the spider and to the column, and said placement means comprises a coupling which acts between said first part and second part. 3. The tripod according to claim 2, wherein the coupling can be selectively uncoupled. 4. The tripod according to claim 2, wherein the coupling comprises first and second members coaxial with each other in a direction substantially perpendicular to the main axis of the spider. 5. The tripod according to claim 4, wherein said first and second coupling members include, respectively, a first and a second toothed portion and are provided respectively on the first and on the second part of the support, said toothed portions constituting means for blocking the relative rotation of said first and second parts of the support. 6. The tripod according to claim 5, wherein said first part of the support comprises a clamping member lockable relative to the spider about said main axis, said first toothed portion being formed on a surface of said clamping member, and said second part of the support comprises a sleeve arrangement with an extending appendage for the removable locking of the column, said second toothed portion being formed on the appendage extending from said sleeve arrangement. 7. The tripod according to claim 6, wherein said locking means comprises a screw clamping device acting between said appendage and said clamping member in order to lock, in reciprocal coupling, said first and second toothed portions in a preselected angular position of the column with respect to the main axis of the spider. 8. A tripod comprising:a spider having a main axis;at least three legs converging in the spider and articulated on the spider;a column having an axis;a support mounted rotatably in the spider about the main axis and supporting the column, the support including:(a) a first and a second part respectively rigidly connectable to the spider and to the column,(b) a coupling acting between the first and second parts for placing the column, and(c) means for removably locking the column in at least two positions in which the axis of the column is angularly inclined with respect to the main axis of the spider; andmeans for blocking the rotation of the support about the main axis, the blocking means disposed between the support and the spider. 9. The tripod according to claim 8, wherein the means for placing the column is incorporated in the means for blocking the rotation of the support. 10. The tripod according to claim 8, wherein the coupling can be selectively uncoupled. 11. The tripod according to claim 8, wherein the coupling comprises first and second members coaxial with each other in a direction substantially perpendicular to the main axis of the spider. 12. The tripod according to claim 11, wherein the first and second coupling members include, respectively, a first and a second toothed portion and are provided respectively on the first and on the second part of the support, the toothed portions constituting the means for blocking the relative rotation of the first and second parts of the support. 13. The tripod according to claim 12, wherein the first part of the support compr ises a clamping member lockable relative to the spider about the main axis, the first toothed portion being formed on a surface of the clamping member, and the second part of the support comprises a sleeve arrangement with an extending appendage for the removable locking of the column, the second toothed portion being formed on the appendage extending from the sleeve arrangement. 14. The tripod according to claim 13, wherein the locking means comprises a screw clamping device acting between the appendage and the clamping member in order to lock, in reciprocal coupling, the first and second toothed portions in a preselected angular position of the column with respect to the main axis of the spider. 15. A tripod comprising:a spider having a main axis;at least three legs converging in the spider and articulated on the spider;a column having an axis; anda support mounted rotatably in the spider about the main axis and supporting the column, the support including:(a) a clamping member rigidly connectable to and lockable relative to the spider about the main axis, the clamping member having a first toothed portion on its surface,(b) a sleeve arrangement rigidly connectable to the column for the removable locking of the column and having an extending appendage with a second toothed portion formed on the appendage,(c) a coupling acting between the clamping member and the sleeve arrangement for placing the column and comprising first and second members coaxial with each other in a direction substantially perpendicular to the main axis of the spider, the first and second coupling members including, respectively, a first and a second toothed portion and being provided respectively on the clamping member and on the sleeve arrangement of the support, the toothed portions selectively blocking the rotation of the support about the main axis, and(d) a screw clamping device acting between the appendage and the clamping member in order to removably lock, in reciprocal coupling, the first and second toothed portions in at least two preselected positions in which the axis of the column is angularly inclined with respect to the main axis of the spider. 16. The tripod according to claim 15, wherein the means for placing the column is incorporated in the means for blocking the rotation of the support. 17. The tripod according to claim 15, wherein the coupling can be selectively uncoupled. 18. A tripod comprising:a spider having a main axis;at least three legs converging in said spider and articulated thereon;a column having an axis;a support in said spider supporting said column, said support including means for placing the column and means for removably locking said column in at least two positions in which the axis of the column is angularly inclined with respect to the main axis of the spider, said support mounted rotatably in said spider about said main axis, anddisposed between said support and said spider, means for blocking the rotation of the support about said main axis,said support comprises first and second parts respectively rigidly connectable to the spider and to the column, and said placement means comprises a coupling which acts between said first and second parts, the coupling includes first and second members coaxial with each other in a direction substantially perpendicular to the main axis of the spider, and said first and second coupling members include, respectively, a first and second toothed portion and are provided respectively on the first and on the second part of the said support, said toothed portions constituting means for blocking the relative rotation of said first and second parts of the support.
