CROSS REFERENCES TO RELATED APPLICATIONS
This application claims priority on International Application No. PCT/US95/10467 filed Aug. 17, 1995 which in turn claims priority on South African 94/6212 filed Aug. 17, 1994.
BACKGROUND OF THE INVENTION
This invention relates to a screen of the type having two or more overlapping sliding leaves or panels. Screens of this type are often used to form bathtub enclosures.
SUMMARY OF THE INVENTION
According to the invention, there is provided a screen which comprises two or more overlapping leaves or panels, an upper rail on which the leaves are hung and along which they can slide, and a lower rail for guiding the lower ends of the leaves during their sliding movement, at least an outer one of the leaves having runners which engage with the upper rail, the runners and upper rail being so constructed that the runners can tilt about a tilt axis extending along the upper rail, and said outer leaf having a pivotally mounted element which is pivotally displaceable between a first condition in which it engages the lower rail for guiding the outer leaf along the lower rail, and a second condition in which it is released from the lower rail, so as to enable the lower end of the outer leaf to swing transversely away from the lower rail, about the tilt axis.
The invention will not be described in more detail, by way of example, with reference to the accompanying drawings.

DETAILED DESCRIPTION
Referring first to FIGS. 1 to 4, reference numeral 10 generally indicates a screen for a bathtub 11, the screen comprising two overlapping leaves or panels 12.1 and 12.2, an upper or head rail 14.1 on which the leaves are hung and along which they can slide, and a lower or sill rail 14.2 for guiding the lower ends of the leaves during their sliding movement. The upper and lower rails 14.1 and 14.2 form a portion of a bathing enclosure and are extruded aluminum sections, both of the same profile, the one being inverted with respect to the other. The leaves overlap to a certain extent, even when in the fully extended condition as shown in FIGS. 1 and 2. In conventional screens this makes it difficult to clean those areas which are between the overlapping parts. To enable these areas to be accessed for cleaning purposes, the leaf 12.2 is tiltable to the inside of the bathtub, as will be described in more detail hereinafter.
The leaves 12.1 and 12.2 each comprise a toughened glass panel 15. The leaf 12.1 is on the outside of the bathtub 11 and is hung
