Device for levelling a support, particularly a support for cameras and cinecameras

Abstract

The invention concerns a device for levelling a support, particularly a support for camera and cinecameras, characterised in that it comprises a base element, provided with means for coupling above a support or tripod, an intermediate element, interacting with said base element, and an upper element, coupling above said intermediate element, and provided above with means for fixing the camera or cinecamera, wherein said base element provides seats for introduction of adjustment screws, interacting with said intermediate element, for adjusting levelling of intermediate element—upper element assembly, wherein said intermediate element is coupled with respect to said base element so as to freely rotate with respect to the same, wherein said upper element is coupled with said intermediate element so as to rotate along with the same with respect to said base element and/or to rotate independently with respect to the intermediate element.

1 . Device for levelling a support, particularly a support for camera and cinecameras, characterised in that it comprises a base element, provided with means for coupling above a support or tripod, an intermediate element, interacting with said base element, and an upper element, coupling above said intermediate element, and provided above with means for fixing the camera or cinecamera, wherein said base element provides seats for introduction of adjustment screws, interacting with said intermediate element, for adjusting levelling of intermediate element—upper element assembly, wherein said intermediate element is coupled with respect to said base element so as to freely rotate with respect to the same, wherein said upper element is coupled with said intermediate element so as to rotate along with the same with respect to said base element and/or to rotate independently with respect to the intermediate element.  
   
   
       2 . Device for levelling a support, particularly a support for camera and cinecameras according to  claim 1 , characterised in that it comprises a base element, provided with means for coupling above a support or tripod, an intermediate element, having an shape complementary with the inner shape of said base element, and an upper element, coupling above said intermediate element, and provided above with means for fixing the camera or cinecamera, wherein the inner wall of said base element is centrally sloped, the lower wall of said intermediate element having a shape complementary, wherein said base element provides seats for lateral introduction of adjustment screws, interacting with said intermediate element, for adjusting levelling of intermediate element—upper element assembly, wherein said intermediate element is coupled with respect to said base element so as to freely rotate with respect to the same, wherein said upper element is coupled with said intermediate element so as to rotate along with the same with respect to said base element and/or to rotate independently with respect to the intermediate element.  
   
   
       3 . Device according to  claim 1 , characterised in that said adjustment screws are vertical screws, between said intermediate element and said base element being provided a further element provided with three grooves coupling with the upper ends of said adjustment screws.  
   
   
       4 . Device according to  claim 2 , characterised in that said means for coupling the base element with the support or tripod are comprised of a threaded hole.  
   
   
       5 . Device according to  claim 3 , characterised in that said threaded hole projects internally with respect to said base element, creating a positioning and rotation pin for said intermediate element.  
   
   
       6 . Device according to  claim 1 , characterised in that said upper element centrally provides a threaded hole for fixing camera or every other element or instrument.  
   
   
       7 . Device according to  claim 1 , characterised in that means are provided opposing to the adjustment of levelling of intermediate element—upper element assembly.  
   
   
       8 . Device according to  claim 7 , characterised in that said means are comprised of a spring, coaxially provided with respect to the levelling device and maintained in the proper position by a screw coupled with said threaded hole provided on said base element.  
   
   
       9 . Device according to  claim 1 , characterised in that three adjustment screws are provided, placed at 120° each other on the outer periphery of the base element, said screws acting on the surface of said intermediate element along a horizontal or inclined direction.  
   
   
       10 . Device according to  claim 1  characterised in that fixing means are provided between the intermediate element and the upper element.  
   
   
       11 . Device according to  claim 10 , characterised in that said fixing means between the intermediate element and the upper element are comprised of a screw passing through a threaded hole realised on said intermediate element and acting on a vertical wall of the upper element.  
   
   
       12 . Device according to  claim 10 , characterised in that said fixing means between the intermediate element and the upper element are comprised of a threaded collar coupled outside said upper element.  
   
   
       13 . Device according to  claim 10 , characterised in that said fixing means between the intermediate element and the upper element are comprised of a screwing coupling between upper element and intermediate element, permitting a micrometric adjustment.  
   
   
       14 . Device according to  claim 1 , characterised in that a levelling reference bubble is provided in the upper element.  
   
   
       15 . Device according to  claim 1 , characterised in that a levelling reference bubble is provided laterally on the device.  
   
   
       16 . Device according to  claim 1  characterised in that a levelling reference bubble is temporarily coupled above said upper element and removed once the levelling has been obtained.
