摘要： A device for providing a lever attachment to round doorknobs having a flexible cylindrical part that adapts to the majority of doorknobs of different diameters, thicknesses and profiles. During the screw tightening the compressible elastomeric material sandwiched between doorknob and cylindrical part of the attachment increases the interface contact surface to take the shape of the doorknob profile. The elastomeric insert has a high coefficient of friction. It prevents slipping of the attachment after tightening.
