A door assembly providing a door frame including an inside steel panel having an inner surface and an outer surface, and a C-shaped section extending about a periphery thereof with a portion of the C-shaped section extending in part parallel to the inner surface of the inside steel panel; an outside steel panel having an inner surface and an outer surface, and a C-shaped section extending about a periphery thereof with a portion of the C-shaped section extending in part parallel to the inner surface of the outside steel panel; an insulating material interposed between respective C-shaped sections of the inside steel panel and the outside steel panel to thermally isolate the inside steel panel and the outside steel panel from each other, and said inside steel panel and outside steel panel being secured together at respective C-shaped sections to form the thermal break system.

A reversible handleset spindle actuator and related method and kit. The spindle actuator is configured to be installed in a handleset. A first thumb-operated lever receiver is positioned to be engaged by a thumb-operated lever connected to the exterior escutcheon of the handleset when the actuator is installed in the handleset configured for a right-handed position. A second thumb-operated lever receiver is positioned to be engaged by the thumb-operated lever when the actuator is installed in the handleset configured for a left-handed position. A spindle is provided for operating a latch mechanism and a rack and pinion mechanism is provided for rotating the spindle, from an initial position, in a first direction when the first thumb-operated lever receiver is moved longitudinally towards the spindle and rotating the spindle in a second direction when the second thumb-operated lever receiver is moved longitudinally towards the spindle.

A safety bolt device comprising: a drop down bolt, the drop down bolt comprising: a cross-member; a first vertical pin attached to a first end of the cross-member; a second vertical pin attached to a second end of the cross-member; a door receiver configured to receive the first vertical pin, the door receiver comprising: a bolt; a jamb receiver configured to receive the second vertical pin, the jamb receiver comprising: a pin; where the door receiver is configured to attach to a door, and the jamb receiver is configured to attach to the door jamb of the door, and where the safety bolt device is configured to prevent the door from being opened when the drop down bolt has been dropped into the door receiver and the jamb receiver.

A locking device configured to lock an opening and closing member with respect to an engagement-receiving member, wherein: an actuating member actuates in accordance with the manipulation of an operating member; a first locking member has a lock linking unit that connects to the actuating member, a first extending portion that extends from the lock linking unit and advances into and retreats from an engaging hole portion formed on the engagement-receiving member in accordance with the actuation of the actuating member, and a second extending portion that extends from the lock linking unit or the first extending portion; and a regulating unit regulates the movement of the second extending portion in the direction that removes the linking of the actuating member and the lock linking unit.

There is provided a connecting structure of a rotating member. One of the rotating support member and the rotating member includes a support shaft. The other of the rotating support member and the rotating member includes a holding portion. The support shaft includes a regulating portion, and a sliding contact portion that is configured to be in sliding contact with an inner periphery of the holding portion. The rotating support member and the rotating member are made of materials that do not join each other when molded from the resin materials. The inner periphery of the holding portion has a shape in which a portion in close contact with the sliding contact portion is continuously formed in a circumferential direction, so that the rotating support member and the rotating member are molded in a state of being connected to each other.
