This invention relates generally to a lock for securing clips used to hold a panel to a wall or ceiling. It includes a panel assembly covering a back surface of a ceiling with a panel, comprising: the panel held face to face with the back surface by a link between a first clip and a second clip; a lock for securing the clips linked together comprising a shim and a flexible wedge connected together; at least a first fastener which connects the wedge to the back surface at a location outside the perimeter of the panel; wherein the shim intermediate the wedge and the back surface is movable to a first position outside of the perimeter to unlock the link to remove the panel from the back surface and in a second configuration the shim is located inside the perimeter where the link is locked to prevent removal of the panel.

A ceiling tile clip includes a top wall, a pair of parallel, spaced side walls that extend downwardly from opposite edges of the top wall and flanges at lower edges of the side walls that extend outwardly. The top wall includes a threaded opening in the center thereof. The ceiling tile clip is configured to be attached to an elongated ceiling grid member by a threaded member that threadedly engages the threaded opening. The elongated ceiling grid member has side surfaces and lower flange portions. When the ceiling tile clip is attached to the elongated ceiling grid member, the top wall of the ceiling tile clip is above the elongated ceiling grid member, the side walls of the ceiling tile clip are alongside the side surfaces of the elongated ceiling grid member and the flanges of the ceiling tile clip are above the flange portions.

A connector 100, a rail system (600), and a panel-mounting system (1) for connecting a lateral rail (200) to a longitudinal rail (300). The connector 100 comprising a first portion 110 configured to attach to the lateral rail (200); and a second portion 112 configured to attach to the longitudinal rail (300), the second portion 112 extending perpendicularly from the first portion 110 to form an L-shape with the first portion 110, the second portion 112 comprising a first retaining lip 120a for engagement with a first corresponding feature (316) of the longitudinal rail (300), wherein the connector 100 is rotatable between an unlocked orientation, in which the first portion 110 may be freely inserted and removed from the lateral rail 200, and a locked orientation, in which the first portion 110 is secured to the lateral rail 200.

A linear wall or ceiling panel comprising and formed from a woven or non-woven fibrous material. Preferably, the material is thermoformable and non-woven and comprises at least one of the group consisting of: bi-core polyester fibers: two different types of fibers having different melting points; a mixture of bi-core polyester fibers and non-bi-core (single core) polyester fibers. The panel is preferably shaped to provide means for mounting the panel to a carrier. Optionally, an end portion may be provided to cover the open longitudinal end of the linear panel.
