Abstract
A door construction for a magnetically shielded room including a door having interior and exterior sections corresponding to the interior and exterior shells of the magnetically shielded room which provides electric and magnetic continuity between the interior and exterior sections of a door and the interior and exterior shells when the door is in the closed position.
Claims26
A door for a magnetically shielded room including a floor, a ceiling and a plurality of walls having an exterior shell and an interior shell disposed within and spaced apart from said exterior shell, said door comprising:
- an exterior door section pivotally connected to the exterior shell;
- an interior door section pivotally connected to the interior shell and spaced apart from the exterior door section;
- and
- a synchronization assembly connected between the interior door section and the exterior door section,
- whereby the synchronization assembly synchronizes the movement of the exterior door section and the interior door section when the door is moved between open and closed positions.
A door construction for a magnetically shielded room including a floor, a ceiling and a plurality of walls having an exterior shell and an interior shell disposed within said exterior shell, the exterior shell includes an inner shield of a magnetically permeable material and an outer shield of an electrically conductive material, the interior shell includes an inner shield of a magnetically permeable material and an outer shield of an electrically conductive material, said door construction comprising:
- a door frame in one of said walls, said door frame including a header, a hinge side, a non-hinge side and a threshold;
- a door connected to the hinge side of the door frame, said door including an exterior door section pivotally connected to the hinge side of the door frame and an interior door section pivotally connected to the hinge side of the door frame and spaced apart from the exterior door section, said exterior door section including an inner shield of a magnetically permeable material and an outer shield of an electrically conductive material, said interior door section including an inner shield of a magnetically permeable material and an outer shield of an electrically conductive material;
- at least one outer locking mechanism connected to the door frame;
- at least one inner locking mechanism connected to the door frame;
- and
- a synchronization assembly connecting the interior door section and the exterior door section,
- whereby the synchronization assembly synchronizes the movement of the exterior door section and the interior door section when the door is moved between open and closed positions.
A door construction for a magnetically shielded room including a floor, a ceiling and a plurality of walls having an exterior shell and an interior shell disposed within said exterior shell, said door construction comprising:
- a door frame in one of said walls, said door frame including a header, two sides and a threshold;
- an exterior door section;
- means for pivotally connecting said exterior door section to the exterior shell;
- an interior door section;
- means for pivotally connecting said the interior door section to said interior shell;
- means connected to the exterior door section and the interior door section for synchronizing the movement between the interior door section and the exterior door section.
