| 1. A shelter, comprising:
a floor,
a roof, and
a plurality of side walls secured to the floor and the roof, wherein at least one of the floor, the roof, and the plurality
of side walls comprises an exterior panel, an interior panel and an attachment device, the attachment device including (i)
a first plate coupled to the exterior panel, (ii) a second plate coupled to the interior panel, and (iii) a third plate pinned
to the first and second plates respectively for relative rotation between the third plate and the first plate about a first
axis of rotation and for relative rotation between the third plate and the second plate about a second axis of rotation such
that during relative movement of the exterior panel and the interior panel between a collapsed position and an expanded position
in which the exterior panel and the interior panel are spaced farther apart from one another than in the collapsed position
to define a cavity therebetween, the third plate pivots between a position in which the third plate is positioned oblique
to the first and second plates and a position in which the third plate is generally perpendicular to the first and second
plates.
