Definitions

• This invention relates generally to shower doors and more specifically, although not exclusively, to folding shower doors or bi-fold shower doors for shower enclosures.
• the folding or bi-fold door In household shower enclosures, folding or bi-fold doors are often used to save space, for example in smaller bathrooms in which there is insufficient space for a standard shower door to be opened.
• the folding or bi-fold door includes a pair of transparent panels hinged together along respective first of their vertical edges.
• a first of the panels is pivotably mounted to the enclosure at or adjacent its second vertical edge while the second panel is slideably connected at or adjacent its second edge to upper and lower horizontal tracks which extend across the width of the opening of the enclosure.
• Such folding or bi-fold doors usually fold inwardly and include some form of handle or gripping means to allow the user to pull the hinged edges toward the inside of the enclosure, which forces the door panels to pivot relative to one another and causes the second edge of the second panel to slide along the tracks thus exposing the opening of the enclosure.
• the folding or bi-fold door of some such shower enclosure designs are said to be 'reversible', wherein the enclosure frame includes a first pivotable connection on both of its sides, each of which is configured to be connected to a second pivotable connection on one of the door panels, i.e. the aforementioned first panel door.
• the door may be flipped so that the pivotable connection may be configured on either side of the opening of the shower enclosure, i.e. wherein the door may be configured to fold to the left side or the right side of the opening.
• one aspect of the invention provides a shower enclosure comprising a frame which defines an opening and a folding or bi-fold door with first and second panels hinged together along respective first vertical edges, each panel being slideably or rollably connected to the frame such that the door is movable between a closed condition in which the panels are substantially coplanar and the door substantially covers the opening and an open condition in which the panels lie at an angle to one another and the opening is at least partially open or uncovered, wherein each of the first and second panels includes a connector for releasably attaching the respective panel to the frame at or adjacent a respective side of the opening.
