Claim:
An apparatus comprising: a housing having at least a first substantially planar panel and a second substantially planar panel, said first panel having an outline with a width and a height, said second panel having an outline with a width and a height, said second panel being arranged adjacent and substantially parallel to said first panel, and said first panel and said second panel are hingeably connected to one another so that the panels can be rotated relative to one another in a plane in which both panels are arranged between a retracted position in which the outline along the width of the first panel substantially coincides with the outline of the width of the second panel, and an extended position that is reached by a substantially 90° rotation of the first panel relative to the second panels, wherein in the extended position, the position of the outline of the first panel along one side of its width substantially coincides with the position of the outline of the second panel along the one side of its height, and wherein a portion of the second panel is a double walled panel with a space there between in which a first portion of the first panel is received and a second portion of the first panel is exposed in the retracted position.
