Abstract: A ceiling system which includes a plurality of grid elements which form a grid framework and a plurality of downwardly accessible ceiling panels. The ceiling panels include a substrate and at least two mounting members. Each mounting member cooperates with the substrate to provide strength and rigidity characteristics to the substrate and to form a grid receiving cavity. Each mounting member further cooperates with a grid element to accurately position the panel relative to the grid framework. When installed, the system provides no visual indications on how the ceiling panel can be removed.

Abstract: A horizontally extending suspended ceiling segment that appears to float in space. Support hangers in an upper tier connect to a grid that forms a lower tier, and cantilever the outward ends of the beams in the lower tier. A perimeter trim strip surrounds the suspended ceiling segment, on the outward ends of the beams in the grid. The support hangers, and hanger wires that support the suspended ceiling segment, are hidden behind the line of sight of a viewer positioned below the segment.

Abstract: A panel for use in constructing a ceiling of an enclosure, particularly a cleanroom without using a grid support.

Abstract: A ceiling panel is provided for use in a grid-type suspended ceiling, wherein the grid includes a plurality of spaced grid runners. The ceiling panel comprises a tile base with perimeter segments and perimeter profiles along at least a portion of at least two of the perimeter segments. Each profile is supportable by the grid runners during suspension. A facing material is secured across the perimeter segments, and extends beyond the perimeter profiles in order to at least partially conceal two of the grid runners when the tile is suspended from the two grid runners and viewed from below.

Abstract: The invention relates to a removable ceiling panel, a rectangular material with a face, a back and four sides with edges, installed from beneath and retained horizontally by its four sides, concealing the profiled suspension grid. The panel is supported at the four sides and it is retained by gravity in the vertical direction. The profiled suspension grid is of the standard type known in the market. The design of the sides of the panel permits carrying out its installation on the basis of simple precise movements, which procedure for installation also forms part of the patent applied for. Said installation movements are not natural and, consequently, render the panels aseismic.

Abstract: The fan filter mounting frame is useful in installation of equipment in a cell of suspension grid systems when the equipment is passed through and is placed in a corner of the cell. The equipment is supported partially directly by the grid and partially indirectly by the grid through an adapting frame insert.

Each of the two legs also extends between its respective rail and the equipment, supporting the equipment on the respective suspension grid rails. Thus, the grid system may be in its design position or condition prior to and during placement and replacement of the equipment without disruption.

Each clip includes a first leg adapted to have at least a portion thereof received in the hem of the ceiling panel. A second leg extends generally perpendicularly from the first leg and includes a detent extending toward the first leg, the detent being adapted to secure the clip to the flange of the runner.

Abstract: A support for a pressure-sensitive elevated floor, comprising a support body, a supporting plate assembly, a membrane, and a containing ring. The support body has a base placed on the ground. The supporting plate assembly is set on the support body and has a lower plate and a cap, which enclose a pressure chamber filled with oil and sealed by an elastic ring. An accommodating chamber is cut into the lower plate at a central position, accommodating a contact switch. The membrane covers the accommodating chamber, being exposed to oil pressure in the pressure chamber. Upon increased oil pressure, the membrane is deformed downward, so that the contact switch is operated and a signal is generated. The containing plate fixes the membrane on the lower plate, having a central opening which allows oil pressure in the pressure chamber to reach the membrane at an exposed area thereof. By peripherally fixing the membrane on the lower plate, the membrane is prevented from loosening.

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.
