A fastening device and a panel system for releasably connecting panels to a wall or ceiling, comprising a latch portion; a base portion; a piston guide; a push latch piston movably arranged and biased between a first retracted position and a second, extended position, wherein a guide track is formed in the push latch piston, and wherein a guide pin is formed on the piston guide, the guide track formed in sections forming an angle to each other, with arrests for the guide pins formed at intersections of the sections, and wherein, when the piston guide is moved relative to the push latch piston towards the retracted position, the guide pin rotates the latch portion to an intermediate position, and when the piston guide is moved back, the guide pin rotates the latch portion from the intermediate position to 90 relative to the initial rest position.

Embodiments of the present invention provide a connection system with a projection on a first connector and a co-operating cavity on a second connector to provide push-through connection of the connectors in first and second configurations in which the projection extends to first and second depths respectively within the cavity, wherein one or more of the projection or cavity is movable in two dimensions perpendicular to a longitudinal axis of the projection when received in the cavity, wherein the first and second connectors have cooperating locking surfaces arranged to engage each other when the projection is received at the second depth to prevent said movement in two dimensions and wherein the cooperating locking surfaces do not engage each other so as to prevent said movement in two dimensions when the projection is received at the first depth in the receiving cavity.

A wall and ceiling panel system which utilizes a concealed resilient beam for securing a panel to a wall or ceiling structure is disclosed. A wall and ceiling panel system having features of the present invention can comprise a panel configured for releasable attachment to a latching assembly. The latching assembly can comprise a resilient beam dynamically secured to a base bracket so as to allow the resilient beam to deflect relative to the base bracket during the panel installation and removal process. The panel can comprise a keyed flange having at least one locking slot configured to mate with the resilient beam, with the panel becoming secured to the latching assembly once the panel's key flange is mated with the resilient beam.

A system for mounting wall panels to a wall, includes wall panels, each including a main wall panel, and at least two bent end sections with a cut-out section and a wall thickness; and a plurality of main fastening extrusions, each including a base section to be secured to the wall, and two parallel, spaced apart flexible and resilient bent end securing walls extending from the base section, each bent end securing wall including a projection facing the other bent end securing wall, the bent end securing walls spaced apart corresponding to the wall thickness of two bent end sections, such that pressing of the bent end sections into the spacing between the bent end securing walls causes biasing away of the bent end securing walls until the projections engage in respective cut-out sections.

Panel connection system for the corner connection of two panels which are arranged at an angled inclination to one another, having a first connecting element having a bearing portion with at least one support surface, by which the connecting element is supported on one of the two panels, and a leg portion which projects at an angled inclination from the bearing portion and which has at least one first engaging structure, and a second connecting element having a bearing portion having at least one support surface, by which the connecting element is supported on the other of the two panels, and having at least one second engaging structure which is situated opposite the support surface, wherein the at least one first engaging structure of the first connecting element is designed for engagement in the at least one second engaging structure of the second connecting element.

A rectangular panel which, on the first and on the second pair of opposite edges, has coupling parts configured for easy installation in a wall or ceiling covering. A locking occurs between the coupled panels; and a wall or ceiling covering that includes such panels.
