Foldable support mechanism

A foldable support mechanism attachable to a wall or other fixed support, comprising a platform member movable between a substantially horizontal, deployed position and a substantially vertical, stowed position in which the platform member is adjacent to and substantially parallel to the said wall or other fixed support and in which a support surface of the platform member faces away from the said wall or other fixed support, and a support structure comprising two links, each pivotally connected to the platform member and at least one of which is pivotally connectable directly or indirectly to the said wall or other fixed support, in which the links of the said support structure each include a respective limb, the two limbs being so formed or so positioned that, in the said stowed position, at least a portion of the said limbs lies in substantially the same plane as one another, parallel to the wall or other fixed support, in which the said limbs are shaped or profiled at the regions where they meet in the stowed position.
