Abstract

An enclosure for a tub or shower comprising a pair of sliding doors which can fold relative to each other along a vertical junction. Each door is supported by an offset hanger and is pivotal about its hanger. The hangers include rollers which slide within an overhead track. The doors can be functioned to slide along the track, to pivot about the hangers and to fold together to fully expose the interior of the enclosure.

Claims2

Dependent claims

In an enclosure of the type having an opening defined laterally between right and left jambs and vertically defined between an upper track and a lower track, the combination of

a first door and a second door suspended from said upper track,
each of said doors having respective inward and outward right and left vertical framing members and a vertical medial axis,
said doors being pivotal from a first position wherein the doors position in planar alignment to substantially close the opening to a second, pivotal position wherein the doors are angularly arranged relative to the upper track to expose the opening;
a handle pivotally connecting the first and second doors,
said handle including means adapted to pivotally hold each door to permit each door to pivot relative to the upper track between the said first and second positions,
hanger means connected to each door, part of said hanger means being in sliding relation within the upper track, the hanger means being adapted to slide the doors between the right and left jambs when the doors are pivoted to the said second position, and a pivot pin connected to the bottom of each door, the pivot pin being in sliding relation within the lower track, the pivot pin being in vertical alignment below the hanger means,
said hanger means and pivot pin being laterally offset from the medial axis of its associated door, said hanger means being positioned between a right or left vertical framing member and the medial axis, each door being adapted to pivot about its said hanger means;
magnetic lock means to lock the doors in the first position, said magnetic lock means comprising a movable first magnet means affixed to a movable jamb strip and a second magnet means affixed to a door, said first magnet means being movable to a position to be attracted to the second magnet means when the doors are in the said first position;
and
means to laterally adjust the position of the movable jamb strip to vary the size of the opening defined between the said jambs,
whereby the doors when pivoted about the hanger means may be slidable along the tracks to a position adjacent either the right jamb or the left jamb to expose the opening.
