The invention relates to improvements in hubs (10) for wall mounting systems for screens, and in particular to a hub (10) for a wall mounting system for a flat panel screen, such as a plasma display or television screen, which enables the screen to be tilted. The hub (10) comprises a casing (18), means for attaching (14) the hub (10) to a screen bracket, means for attaching the hub to an arm of a wall mount, and a tilt member (25). The tilt member (25) has a sliding member which is located within an arcuate cavity (29) in the casing such that the sliding member and casing are slidable relative to each other to enable a screen attached to the mounting system to be tilted about a horizontal pivot axis. The arc is defined by the cavity (29) having its centre, which forms the pivot axis, offset from the centre of gravity of the screen. The hub (10) further comprises a compression spring (32) located within the casing and biased to provide a counterbalancing force so that the screen remains stationery in any position. |
