Abstract: A bifold door comprises a pair of door panels 12.1, 12.2 joined to one another along a centre hinge 14. Each door panel, at the end thereof remote from the center hinge, is supported on a track 16 by a runner assembly 18 to which the door panel is pivotally connected. Each runner assembly is provided with a cam 32 whereby the runner assembly can releasably be locked in position with respect to the track.

Abstract: A shower cubicle enclosure is disclosed. It has a fixed panel and a slidable panel for opening and closing an access opening, and a rail which defines a cylindrically curved track. The slidable panel has runner elements which cooperate with the track so as to guide the slidable panel for displacement between an open position in which the slidable panel is adjacent and spaced traversely from the fixed panel, and a closed position in which the panel closes the access opening. The fixed and slidable panels are both cylindrically curved. A parking element draws the trailing end of the slidable panel traversely towards the fixed panel as the slidable panel approaches the closed position, thus forming a water tight seal between the slidable and fixed panels.
