Abstract: A suspended ceiling system in which the grid runners are largely concealed by the panels to produce a distinctive high quality appearance. In various illustrated embodiments, the visual effect is produced as a result of the panels being separated by a relatively narrow gap in two perpendicular directions or by a narrow gap in one direction and essentially no gap in the perpendicular direction, and the grid being recessed above the main face of the panels. The panels are accurately positioned on the grid by metal clips, normally permanently attached to the panels, which engage upstanding flange portions of the grid runners. The accurate positioning afforded by the clips assures that visually distracting variations in the size of the narrow gaps are avoided. The clips can also serve to avoid accidental dislodging of the panels.

Also provided is a door frame system. The door frame system comprises a first leg member, a second leg member, a header, a first door frame clip, and a second door frame clip. The second leg member is substantially parallel to the first leg member.

Abstract: A screen door made of foamed, closed-cell, solid-core polyvinyl chloride includes two rails and two stiles connected together to form a rectangular frame having an opening. A groove is milled into the frame around the opening. The screen that is to cover the opening is fastened to the frame by pressing it with a spline into the groove. The rails and stiles are connected using dowels in addition to adhesives, or, alternatively, using screws and traditional mortise and tenon joints. Holes are drilled into the stiles and then screws are driven into the rails from within the holes. The holes are then filled with foamed plastic plugs over the screws. The screen door can be cut and trimmed at the job site to fit it to the particular door frame, removing up to about an inch from each edge.

Abstract: An assembly system used to build two pane thermoacoustic windows for houses and buildings is provided. The assembly system uses a set of profiles and joints and a permanently installed valve to assemble the window frame without a fusion welding machine. The system creates an airtight chamber directly on the frame. The valve allows the assembler to evacuate the air in the airtight chamber to make a vacuum, or to inflow a gas. The system improves the insulating thermal and acoustic capacity of the window, and allows a supplier to sell the components to build the window, which is then assembled by snapping together profiles and joints. The system can also be applied to assembly one pane window and for other purposes.

Abstract: A frame for forming a housing of a group of air-handling units mainly includes a plurality of extruded plastic angle columns and a plurality of integrally injection molded plastic three-way unions. The plastic angle columns and three-way unions eliminate the problem of condensate on the surfaces of the housing and allow the air-handling units to operate with reduced energy consumption, because the plastic columns and unions have low coefficient of thermal conduction and would not easily have a surface temperature lower than a dew point temperature of ambient air outside the housing. Meanwhile, the extruded plastic angle columns and the injection molded plastic three-way unions can have standardized dimensions and be efficiently produced through mass production, the frame for the housing of the air-handling units can therefore be formed at reduced labor and time.
