Abstract

A structure having a movable panel (5) has a support frame (8) having side portions (8b) slidably mounted on supports to allow sliding movement of the frame (8) between a retracted and an extended position. The movable panel (5) is mounted on the frame (8) via interengaging track means preferably comprising a track of part-circular cross-section (1) and arcuate means (2). The arcuate means (2) allow a first tilting of the movable panel (5) from a flush-fitting plane to an inclined plane on sliding movement of the frame (8) from the retracted to the extended position, and also allow a subsequent second tilting of the movable panel (5) from the inclined plane to a non-flush plane substantially parallel to the flush-fitting plane. The interengaging means (1,2) allow lateral sliding of the movable panel (5) in the non-flush plane. Thus one end of the movable panel (5) may be transferred between planes before the opposite end, enabling one person to handle large panels with ease. The need for large internal frames is obviated.
