A camera support bowl clamp device comprises a bowl member of a pan tilt head suitable for supporting a broadcast or motion picture camera arranged within a recessed member of a camera support, whereby said bowl member is attached at one end of a shaft and a clamping cup arranged at an opposite end of said shaft, whereby said opposite end extends through said recessed member of a camera support; wherein said clamping cup located at a first limit position applies a clamping force to a surface of said recessed member of a camera support which subsequently pulls said bowl member, via said shaft, down into said recess and applies a second clamping force from a surface of said bowl to a cooperating surface of said recessed member, and at a second limit position releases said clamping force to said recessed member which subsequently releases said second clamping force by separating said surface of said bowl from said cooperating surface of said recessed member; characterised in that said clamping cup further comprises a clamp adjustment member, a resilient member, and a lever pivotally attached to said clamp adjustment member whereby the movement of said lever to a first position compresses said resilient member to locate said clamping cup at said second limit position, and at a second position said lever allows the resilient member to decompress to locate said clamping cup at said first position. |
