  • Nonslip surface for camera tripod panheads
    Publication number: 20020109053
    Abstract: A nonslip resilient surface on the camera attachment area of a camera panhead, which utilizes readily available o-rings (1) arranged concentrically about the camera attachment screw (1B). The depths of successive ring grooves can be graduated to allow for more protrusion of the outer o-rings to assure positive seating with the camera base (2). The resilient o-rings can be retained in their grooves by their own elasticity.
