Abstract: The invention relates to improvements in tiltable wall mounts, and in particular to a self-locking tiltable wall mount for a screen, such as a plasma display or television screen. The tiltable wall mount for a screen comprises wall attachment means for attaching the mount to a substantially vertical surface and screen attachment means for attaching a screen to the mount. The screen attachment means are pivotally connected at one end to one end of the wall attachment means. The wall mount also has a tilt mechanism interconnecting the mount and screen attachment means, said tilt mechanism comprising a locking device comprising at least one cam follower which is biased into abutment with a stepped cam surface projecting from the wall attachment means to prevent relative movement between the wall and screen attachment means.
