Abstract: A collapsible storage structure for the storage of an object includes a base having front and rear ends and on or over which the object can be placed. The base comprises a pair of longitudinally extending, spaced, parallel rails. A plurality of inverted, substantially U-shaped canopy supports span the base from one rail to the other and are mounted so as to be foldable with respect to the base. A canopy is carried on the canopy supports, the arrangement being such that, when the canopy supports are in a collapsed configuration, the object can be positioned with respect to the base, whereafter the canopy supports can be displaced to an configuration in which the canopy covers the object. A transport mechanism comprises a pair of carriages. One carriage is slidably arranged on each rail, the carriages carrying at least certain of the canopy supports and being displaceable between a first position in which the canopy supports are collapsed and a second position in which the canopy supports are erected.

Abstract: An access control booth 10 includes a housing 12 having a base member 26, a roof member 28 and a side wall portion 30 extending between the base member 26 and the roof member 28, the side wall portion 30 having a circular inner plan profile to define a pair of opposed arcuate access openings 14, 16. A pair of counter-pivoted arcuate members 20, 24 close the access openings 14, 16, respectively. Each arcuate member 20, 24 has a first arm pivotally mounted within the roof member 28, a second arm pivotally mounted beneath the base member 26 and an arcuate wall portion extending between the first arm and the second arm. A torsion-bar assembly is connected to the first arm and the second arm of each arcuate member 20, 24 for inhibiting twisting of the arcuate member 20, 24 as it pivots, the torsion-bar assembly being arranged inwardly of the arcuate wall portion of the arcuate member 20, 24.
