A portable collapsible enclosure that can be erected for use or collapsed for transport or storage quickly and easily by a single person exercising minimal effort and possessing minimal skill. The enclosure comprises a plurality of frame members for defining the shape of the enclosure and for supporting a covering for the enclosure, expandable and foldable linking members interconnecting the plurality of frame members and being expandable to position the plurality of frame members and the enclosure defined thereby in an erected state, and foldable to position the plurality of frame members and the enclosure defined thereby in a collapsed state; and actuator members connected to the linkage members for expanding and folding the linkage members to erect and collapse the enclosure. The actuator members preferably comprise fluid-driven linear actuators that once actuated, operate automatically to erect and collapse the enclosure.

A collapsible enclosure comprising: a plurality of frame members for defining the shape of the enclosure and for supporting a covering for the enclosures; expandable and foldable linkage means interconnecting the plurality of frame members, the linkage means being expandable to position the plurality of frame members and the enclosure defined thereby in an erected state, and foldable to position the plurality of frame members and the enclosure defined thereby in a collapsed state; and fluid-driven linear actuator means connected to said linkage means for expanding and folding the linkage means to erect and collapse the enclosure by moving said frame members and said enclosure defined thereby along an arcuate path when said enclosure is erected and collapsed, said fluid-driven linear actuator means comprising substantially self-operating fluid-driven linear actuator means which when once actuated for linear movement in a first direction to expand said linkage means or in a second direction to fold said linkage means will automatically complete its movement in the first and second directions to substantially automatically erect and collapse the enclosure, respectively.
