A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so user can stand on the deep step in place objects into the attic without having to climb into the attic. A method. A deep step.

A mounting system includes a frame that defines a truss structure and a plurality of mounting locations within the truss structure. The plurality of mounting locations are configured to interchangeably couple to one or more members, including one or more of an access panel, a light troffer or a boom mount.

A removable panel includes a fixed section, an opening section able to be reversibly nested in the fixed section, at least one sling fastened to the fixed section at a first end and reversibly fastened to the opening section at a second end. The removable panel also includes at least one attachment means making it possible to maintain the opening section engaged in the fixed section. Each attachment means including a central portion in pivot connections with the opening section, the central portion having at an upper end an attachment portion intended for coming into contact with the fixed section, and at a lower end a manipulation portion. A suspended ceiling is also provided and includes an assembly of modular panels at least one of which is the removable panel.

The present disclosure relates generally to ceiling panels, for example, suitable for use forming a ceiling surface. The present disclosure relates more particularly to a ceiling panel including a panel body and a bracket. The panel body includes an upper surface, a lower surface, a first end, a second end, a first lateral side, and a second lateral side. The bracket extends upward from the upper surface of the panel body and is offset from a center of gravity of the panel body toward the first end. The bracket includes an upper fastener configured to attach the ceiling panel to a frame element of a ceiling grid. An angle of the panel body is adjustable with respect to the attachment of the upper fastener of the bracket.

A baffle tile that folds from a flat configuration into a three-dimensional configuration is disclosed. In the three-dimensional configuration, it includes a rim portion and a baffle portion. The rim portion is split into halves. Each half of the rim portion terminates in a pair of upwardly-folded, spaced-apart tabs. When the baffle tile is in its three-dimensional configuration, each tab meets and abuts its counterpart from the other half of the rim portion. Each tab has a notch in it, arranged such that the notches of abutted tabs are aligned. A retaining structure inserts into each set of aligned notches. The retaining structures prevent the tabs of the baffle tile from separating. In some cases, a single retaining structure that has approximately the same size as the baffle tile itself may also serve as a cap to enclose the tile.

A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so user can stand on the deep step in place objects into the attic without having to climb into the attic. A deep step for a ceiling ladder.

An access panel system for providing access into a space behind a surface, such as a ceiling, is disclosed. The system comprises an access panel frame adapted to be disposed in a corresponding opening in the surface, the frame formed from a first sheet of drywall, the access panel frame having an upper frame surface, a lower frame surface and a frame opening, the frame opening formed by milling a section from the sheet of drywall. The system further comprises an access panel formed from a second sheet of drywall, wherein the access panel includes a stepped portion and a flanged portion milled from the second sheet of drywall, and wherein the stepped portion is laterally dimensioned to fit into the frame opening and the flanged portion is adapted to engage the upper frame surface.

The techniques and systems (e.g., elevator shelf systems) for efficient shelving and item storage are described. For instance, one or more aspects of the described example shelving systems may provide for more compact and more stable shelving systems (e.g., saving more space cabinets for storage rather than shelving operating mechanisms, providing more stability against lateral and in/out swings during descent and ascent, providing capabilities of handling shelving loads up to 30 kg, etc.). One or more inventive aspects of the techniques and systems described herein include the efficient integration and configuration of drawer slides (e.g., for in/out shelf motion), as well as the efficient integration and configuration of a belt and reel system (e.g., for up/down shelf motion).

A ceiling system is provided for use in a building space having a plurality of walls. The ceiling system includes a grid system that extends to at least two of the plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system; and a plurality of ceiling tiles that are supported by the grid system and, with the grid system, create a barrier between the occupiable space and the plenum space, the plurality of ceiling tiles including three different polygonal non-rectangular ceiling tiles
