发明名称 Collapsible frame
摘要 A collapsible frame for use in erecting tents, insect screen rooms, shade awnings, canopies and the like at camp sights, back yard patios and other outdoor venues. The collapsible frame includes a plurality of telescopic legs for providing vertical structural support and a plurality of corner pin joints with one of the pin joints fixedly mounted upon a corresponding one of each of the telescopic legs. A plurality of horizontal support arms is included with one of the arms positioned between every adjacent pair of telescopic legs and attached to the corresponding corner pin joints. A mid-span hinge which includes a sliding sleeve is centrally positioned along each of the horizontal support arms. The mid-span hinge is flexibly collapsible when the sleeve is disengaged and is rigidly inflexible when the sleeve is engaged. A bottom slider is adjustably mounted upon each of the telescopic legs and is attached to the horizontal support arms which are connected to the corresponding corner pin joint. Finally, a plurality of top support members is included where each is anchored in a corresponding corner pin joint for stabilizing the frame. In the present invention, the telescopic legs, mid-span hinges and bottom sliders each cooperate to collapse the frame.
