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.

An acoustic ceiling tile and a dynamic acoustic ceiling system that includes multiple ceiling tiles that can be quickly and easily installed onto ceiling structures utilizing attached or embedded magnetic assemblies to provide an aesthetically pleasing image, such as an fluctuating image, along with a reduction in unwanted noise or room acoustics, wherein the attached or embedded magnetic assemblies are configured to be removed from the ceiling tile, and then configured to be easily placed or located onto a different location on the ceiling tile as needed, to allow for optimal installation of the ceiling tile onto the ceiling structure.

A linear profile support element and ceiling grid lighting module for suspended ceiling systems is provided. The linear profile support element is configured to connect onto a T-bar within a ceiling grid system and has at least two lateral supporting portions to hold an optical device and ceiling panel in position with one or both offset from the ceiling grid plane. In embodiments having the ceiling panel on an upper lateral support portion, a recessed volume is created in the ceiling grid system which functions as an optical cavity for light from an optical device mounted at the lower lateral supporting portion. With a ceiling panel mounted on the lower lateral supporting portion, the panel is dropped with respect to the ceiling grid plane and the optical device can be aligned at an upper lateral supporting portion horizontally, for example to project light onto a surrounding ceiling panel and provide indirect lighting from the ceiling. Ceiling panels mounted on the lateral supporting portions can be either standard ceiling grid panels or panels alternatively configured for specific appearance or reflectance properties. Various embodiments are described that provide a range of useful mounting options for both the optical system and ceiling panel, including configurations with tilted ceiling panels. Multiple linear supporting elements can be used to create an enhanced three-dimensional appearance to the suspended ceiling system as well as interesting features such as fully or partially illuminated panels, cavities, coves or edges. Ceiling grid lighting module embodiments integrate the linear profile support element with an optical device for pre-configured light distribution and form factor that can be easily installed in a ceiling grid system.

An anchor bolt assembly according to an embodiment of the present disclosure includes an anchor body provided with a plurality of pointed protrusions on an upper surface thereof, an anchor shell provided with open upper and lower sides thereof, extrapolated to a lower side of the anchor body, provided with a first incised part having a “Y” shape at an equal interval along a circumference of the anchor shell, and provided with a second incised part having a “v” shape at an equal interval along a longitudinal direction of the first incised part, a tightening member screwed to the anchor body through a screw thread provided on an inner circumferential surface of the tightening member, and provided with a processing part for increasing frictional force along an upper circumference of the tightening member.

A ceiling panel of which both end portions in a second direction are held on a ceiling base having a long shape extending in a first direction and being provided in parallel spaced in a second direction the ceiling panel includes a panel body, a hooked portion, and a hooking portion. The hooking portion has a folded part formed by being bent into a room side from a tip end portion in an extending direction of an extension portion extending outward in the first direction from the second end portion in the first direction, and by being further folded inward in the first direction, and the hooked portion keeps hooking and holding of the folded part with a second end portion in the first direction of an adjacent ceiling panel to be provided in the first direction being positioned upward further than the first end portion in the first direction.

A ceiling suspension system is disclosed and includes a plurality of grid members configured to form a grid for the ceiling suspension system, each grid member comprising a bulb, a web and a flange. The system also includes a plurality of wall support brackets configured to mount the grid to walls in a structure. Each wall support bracket comprises a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back. Further, the upper flange is generally V-shaped when viewed longitudinally and each wall support bracket only one tab in the lower flange for each grid member. Moreover, the only one tab is configured to engage and retain the flange of a respective grid member, such that the respective grid member rests on the lower flange.

An acoustic ceiling tile and a dynamic acoustic ceiling system that includes multiple ceiling tiles that can be quickly and easily installed onto ceiling structures utilizing attached or embedded magnetic assemblies to provide an aesthetically pleasing image, such as an fluctuating image, along with a reduction in unwanted noise or room acoustics, wherein the attached or embedded magnetic assemblies are configured to be removed from the ceiling tile, and then configured to be easily placed or located onto a different location on the ceiling tile as needed, to allow for optimal installation of the ceiling tile onto the ceiling structure.

A ceiling system which includes a substrate and securing members configured to engage a grid system to mount the substrate to the grid system. The securing members may include a mounting flange positioned with its bottom surface adjacent to the substrate. The mounting flange may be coupled to the substrate via fasteners. The securing members may further include a positioning member protruding from a top surface of the mounting flange and terminating in a distal edge. The positioning member may have a first side edge and a second side edge. The securing members may include a grid engagement member extending from the distal edge of the positioning member. The grid engagement member may be located centrally between the first and second side edges of the positioning member. The grid engagement member may have a U-shaped engagement portion configured to engage a grid member of the grid system.
