Abstract
An access device for providing access between a lower level and an upper level, the access device including a main body mounted for pivotal movement about a main body pivot mounting between an access position in which it enables access between the upper and lower levels and a stowed position in which a substantial part thereof is disposed above the main body pivot mounting; a drive mechanism operable to cause movement of the main body between the operative and stowed positions, the drive mechanism including a drive device and a link mechanism, the link mechanism including control link means mounted for pivotal movement about a control link pivot mounting, the control link being operatively connected to the drive device at a first connecting point, coupling link means operatively connecting the main body to the control link means, the coupling link means being connected to the main body at a second connecting point, the arrangement being such that actuation of the drive means causes the connection between the coupling means and the main body to be displaced upwardly or downwardly to move the main body between the access position and the stowed position.
