Abstract: A cupola body fabricated from extrusions preferably includes a bottom frame, a first top frame, a second top frame and eight side rails. The bottom frame includes four bottom rails attached to each other with bottom fasteners. The first top frame includes four first top rails attached to each other with top fasteners. The second top frame includes four second top rails attached to each other with the top fasteners. A bottom of the eight side rails are attached to the bottom frame with side fasteners and a top of the eight side rails are attached to the second top frame with the side fasteners. The four bottom rails include a bottom glazing channel. The eight side rails include a side glazing channel. The four second top rails include a top glazing channel. The glazing channels are sized to receive four glazing panels.

Abstract: A door latch includes an S-handle, a mounting plate, a locking mounting plate, a handle latch and a locking spring. One end of the S-handle is terminated with a latch extension. A locking key extends from the S-handle. Each mounting plate includes a handle hole. A lock slot is formed adjacent the handle hole in the locking mounting plate. The lock slot receives the locking key. The handle latch includes a hook member and at least one mounting flange extending from a rear of the hook member. The hook member is sized to receive the latch extension. The S-handle is secured to a door with the mounting plates and the handle latch is secured to a surface, adjacent the door. A second embodiment of a door latch includes a torsion spring. The second embodiment of the door latch is used to lock a sliding door.

Abstract: A method of providing precut trim pieces for a structural sliding door includes a vertical trim piece with one end that fits over a rail lip of a vertical rail, instead of under the rail lip. The rail lip terminates a trim extension of the vertical rail. Attaching the vertical trim piece over the rail lip enables the vertical trim piece to have horizontal adjustment relative to the trim extension. The manufacturer is able to supply precut lengths of horizontal and angled trim pieces, because the vertical trim piece may be horizontally adjusted to compensate for an out-of-square door.

Abstract: A hollow metal door having a foam retained tapping structure includes a hollow metal door, at least one tapping structure, and a quantity of foam injected into the hollow metal door. The hollow metal door includes a pan member and a lid member which is attached to the pan member to form the hollow metal door. The tapping structure preferably includes a fastening tube and an attachment pedestal extending from the fastening tube. A bottom of the pedestal is attached to an inside perimeter wall of the pan member adjacent where a door component is to be attached. The tapping structure is preferably attached to the inside perimeter wall of the pan member with double sided tape, but other fastening methods may also be used.

Abstract: A cupola roof having cupola roof panels with snap-fit edges preferably includes four roof panels. In a first embodiment, there are four combination cupola roof panels. Each combination cupola roof panel has a female snap-fit edge on one side and a male snap-fit edge on the other side. In a second embodiment their are two male cupola roof panels and two female cupola roof panels. The male cupola roof panel has a male snap-fit edge disposed on each side thereof. The female cupola roof panel has a female snap-fit edge disposed on each side thereof.

Abstract: The large overhead bi-fold doors of the present invention are hinged along a centerline and hung by hinges from the top of the door opening. A motor mounted inside and above the door opening is connected to one end of a cable, the other end of which passes around a pulley at the bottom of the door and then upwardly to a latching mechanism located beneath the horizontal hinge line of the doors. When the motor is activated, the cable pulls on a dog or arm connected to a shaft which also carries the hook of a latching device. The hook engages a strike attached to the frame of the building on which the door is mounted, and when the motor is activated, the cable pulls on the dog which disengages the hook from the strike and further tension on the cable by the motor raises the door to an elevated position.
