Abstract
A self-aligning jamb jack apparatus with a cylindrical threaded adjustment component that has adjustment component threads on the exterior wall and smooth surface on the interior walls, the cylindrical threaded adjustment component extending through a cylinder with a smooth exterior to a ball (or cut-off sphere), the smooth surface extending through the cylinder and the ball (or cut-off sphere). The jamb jack apparatus also has a platform base with a socket configured to encompass the ball (or cut-off sphere) such that the platform base pivots around the ball (or cut-off sphere). The self-aligning jamb jack apparatus is installed in a door or window jamb (or any other appliance) to connect and regulate the space between the jamb and the rough framing.
Claims20
An apparatus comprising:
- a cylindrical threaded adjustment component with a cylindrical surface on an interior wall and an adjustment component threads on an exterior wall, the cylindrical threaded adjustment component extending through a cylinder with an exterior surface to a cut-off sphere, the cylindrical surface extending through the cylinder and the cut-off sphere;
