  • Patent number: 5560385
    Abstract: A collapsible play structure has one or more play modules connected together, each play module comprising at least three foldable frame members, each having a folded and an unfolded orientation. A fabric material substantially covers each frame member to form a side panel for each frame member when the frame member is in the unfolded orientation. Each side panel further comprises at least three sides. The left side of each side panel is connected and hinged to the right side of an adjacent side panel, and the right side of each side panel is connected and hinged to the left side of another adjacent side panel. The bottom side of each side panel is adapted to rest on a supporting surface to support the play module.

  • Patent number: 5467794
    Abstract: A collapsible shade structure includes a plurality of foldable frame members each having a folded and an unfolded orientation. A fabric material is provided for substantially covering the frame members to form a side panel for each frame member, each side panel assuming the unfolded orientation of its associated frame member. Interconnecting portions of the fabric material form a hinge portion between each frame member. Alternatively, frame retaining sleeve portions may be used to interconnect and retain two or more frame members from two or more adjacent side panels and to act as hinge portions. The structure may be folded and stored by folding the side panels and their corresponding frame members on top of each other about the hinge portions to have the side panels and frame members overlying each other.

  • Patent number: 5439016
    Abstract: A substantially cone-shaped tent comprises a plurality of rods connected to each other in the region of the top of the tent and arranged to extend divergingly downwardly to the ground on which the tent stands and bear thereagainst while each forming substantially a generatrix of an imagined cone, a substantially cone-shaped tent cloth adapted to bear on the outside of and be carried by the rods, and means adapted to interconnect adjacent rods at a distance from the top of the tent so as to hold them in a determined mutual position. Said interconnecting means comprise elongated rigid elements with a first engaging member at each end thereof, and the rods have second engaging members arranged to enter into engagement with the first engaging members arranged on the corresponding rigid elements when connecting adjacent rods by means of the rigid elements and by that hold two adjacent rods at a mutual distance defined by the rigid element.
