Combination-action slide and hinge swinging door

A dual action combination slide and swing door comprising:

• a first door panel unit hinged to a vertical door frame jamb using hinges secured to the jamb with hinge screws;
• a second door panel attached to the first door panel, creating a two-panel connected door assembly, in a plane adjacent and parallel to the first door panel with a drawer slide mechanism between the two door panels screwed together so that the second door panel would move in parallel slide or rolling movement from a partial overlapping position to a full overlapping position or in addition to the two-panel assembly a third panel attached to the second panel creating a three-panel connected door assembly, in a plane adjacent and parallel to the second door panel with another conventional drawer slide mechanism between the second door panel and the third door panel connected in the same manner so that the third door panel could move in a parallel slide or rolling movement in relation to the second door panel from a partial overlapping position to a full overlapping position;
• a roller assembly that is attached to the second door panel and a corresponding mating partial length flat support track attached to and along a door frame top horizontal member if a two door panel unit assembly or two or more roller assemblies attached to the third door panel if the door assembly consists of three panel units;
• a magnetic and gravity locking bar assembly that automatically blocks and unblocks the second door panel unit of a two door panel assembly from sliding or rolling action or blocks and unblocks the second and third door panel units of a three door panel assembly from sliding or rolling action comprising a permanent magnet mounted on the top horizontal member and a lock bar mounted on one of the panels;
• whereby the second or second and third door panels roll from a partial overlapping position to the full overlapping position relative to the first hinged door panel when the first door panel is positioned in and parallel to the doorway frame and to one another and only from this fully overlapped position allowed to pivot rotate out from the doorway;
• whereby starting from the fully overlapped position of the second door panel or the second and third door panels relative to the first hinged door panel when the first door panel is located in the door frame parallel with the frame at the start of the rolling action to a partial overlapping position, the roller assembly or assemblies, aligned with the corresponding flat track attached to the top door frame horizontal member, engages said track by rolling onto said track allowing for said track to assume partial weight support of the second or second and third rolling door panels with the amount of door weight support increased in relation to the amount of decreasing overlap and with the opposite weight bearing affect occurring to the point whereby the roller disengages from the track;
• whereby with all of the door panels overlapping one another fully relative to the hinged door panel when located in and parallel with the doorway frame, the two door panels or three door panels will rotate out of the doorway frame and during the start of the rotation within less than the first one inch of rotation travel, the lock bar component of the lock bar assembly once the panels are rotated and the lock bar is no longer attracted to the magnet, will drop down and block the second or second and third door panels from any rolling action during rotation, and the blocking action will remain fixed until the two or three door panels are rotated back into within less than the last one inch of rotation travel to a position where the magnet will attract and raise the lock arm, thereby disengaging the door panel lock bar from blocking the rolling action of the rolling door panel or panels.
