Single action assembly temporary display

A structure comprising:

• an elongate beam having a longitudinal axis and a pair of ends, each end defining a pivot axis;
• a shelf pivotably connected to the beam for movement about the longitudinal axis between
• a nested position, whereat the shelf is generally coplanar with the beam;
• and
• a supporting position, whereat the shelf is disposed in angular relation to the beam,
• a frame including
• for each end of the beam, a sidewall, the sidewall connected to the beam end for
• which it is provided for movement about the pivot axis defined thereby, between
• a nested position, whereat the sidewall is generally coplanar with the beam and extends away from the beam;
• and
• a supporting position, whereat the sidewall is disposed in angular relation to the beam;
• and
• a planar support movable between
• a nested position, whereat, when the shelf is in the nested position, the
• planar support is generally coplanar with the beam;
• and
• a supporting position, whereat, when the shelf is in the support position thereof, the planar support is disposed in parallel, spaced relation to the beam,
• a linkage coupling the sidewalls, planar support and shelf together such that
• the following movements are mechanically linked to one another
• movement of the shelf from the nested position to the supporting position;
• movement of each sidewall from the nested position to the supporting position;
• movement of the support from the nesting position to the supporting position;
• the shelf extends to, and is supported by, the planar support when the shelf is in the supporting position.
