Abstract:
The door actuator generally has a receiving structure having a door carriage path; a first coil assembly and a second coil assembly both being mounted to the receiving structure along a common coil assembly plane and being longitudinally spaced from one another along the door carriage path by a spacing distance; and a door carriage being slidingly received by the receiving structure, the door carriage having a plurality of alternate-pole magnets provided along a magnet plane being parallel and spaced apart from the coil assembly plane, the first and second coil assemblies being operable to move the door carriage back and forth between the two ends of the rail.
Abstract:
The locking mechanism is generally adapted to a door system having a door unit slidably mounted to a door frame to open and close by sliding longitudinally along the door frame. The locking mechanism has : a pivoting member pivotally mounted to one of the door frame and the door unit for pivoting about a pivot axis, and a hook member spaced apart from the pivot axis such that the hook member can pivot about the pivot axis via the pivoting member; and a guide member secured to the other one of the door frame and the door unit, the guide member having a channel formed therein to receive the hook member when the pivoting member is moved toward the guide by said sliding of the door, and subsequently maintain engagement with the hook member.
