发明名称 Collapsible canopy with auto erect roof support structure
摘要 A canopy shelter has a plurality of corner support forming legs that may be positioned on a support surface. Scissor assemblies interconnect adjacent ones of the corner supports and are each pivotally connected at one portion to the top ends of the respective corner supports and are each pivotally connected at another portion to slide brackets slideably mounted on each of the respective corner supports. Roof support members are pivotally connected to a respective slide bracket on a corner support. Thus, the framework may be collapsed in a stored state yet expanded to an expanded state by spreading the corner members apart from one another. This automatically raises the apex which may also include a center post structure. Latches are provided to retain the slide brackets in position to hold the framework in the expanded state. A flexible covering is centrally supported by the apex to form a canopy top, and cables may be provided between the top ends of the corner supports and the apex to further support the flexible covering. Side panels and a front panel having a doorway may be used to enclose a protected space. The corner supports may be formed by telescoping leg sections. Each roof support may be formed by a plurality of extendible sections that may be open and closed either by pivotally folding or by telescopic construction, and latches are provided to hold the roof sections open.
