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.
A structure comprising support means, a support frame having a front portion and two side portions, said two side portions being slidably mounted on said support means to allow sliding movement of said frame between a retracted and and extended position relative to said support means, a movable panel mounted on said front portion of said frame, and interengaging track means mounting said movable panel on said front portion of said frame and comprising arcuate members operable for allowing a first tilting of said movable panel between a flush-fitting plane and an inclined plane on sliding movement of said frame from said retracted position to said extended position thereof and for allowing a second tilting of said movable panel between said inclined plane and a non-flush plane substantially parallel to said flush-fitting plane, said arcuate members of said interengaging track means being further operable to permit said movable panel to move laterally along said front portion of said frame when said movable panel is in said non-flush plane.
