Wedge
A collapsible wedge 100 moveable between collapsed and wedge configurations for restricting movement of a door, the collapsible wedge comprising a wedge portion 104 to abut the door, and at least one, preferably two sidewall portions 102a connected to the wedge portion, wherein the sidewall portion is moveable with respect to the wedge portion to move the collapsible wedge between the collapsed and wedge configurations. The sidewall is preferably rotatably connected to the wedge portion, e.g via an area of reduced thickness (108b Fig 1), hinges e.g. a butterfly hinge, or a foldable connection. The rotatable connection may have tapered faces to limit the rotation of the sidewall portion. There may be a retaining portion (106 Fig 7) rotatably connected to one end of the wedge. A reinforcing element 132 134 may be located inside the wedge to increase the rigidity and strength of the wedge. The reinforcing element may include a reinforcing side wall 132 located perpendicular to the wedge and formed from a folded section of the wedge portion.
