Abstract

A mechanism (10) for locking a first part (20) of a device (30) in a plurality of positions relative to a second part (40) of the device (30), comprising: a locking member (60) moveable between an operative configuration in which movement of the first part (20) relative to the second part (40) is prevented and an inoperative position in which movement of the first part (20) relative to the second part (40) is permitted; and an actuator (70) for moving the locking member (60) from the inoperative position to the operative position as the actuator (70) moves from a first configuration to a second configuration. In accordance with one aspect of the invention, the locking member (60) is biased in the inoperative position when the actuator (70) is in the first configuration. In accordance with a second aspect of the invention, the locking member (60) is housed in a chamber (80) configured to force the locking member (60) against a locking surface (50) when a downward force is applied to the actuator (70) whilst the locking member (60) is in the operative configuration.
