<p>The collapsible canopy framework (11) formed of telescoping corner support members (14) which is adapted to support a canopy covering (12). The framework (11) includes scissor members (40) which is formed of scissor bars (41 and 42). The scissors units (40) are connected one to another as well as connected in the form of single and multiple scissor trusses to the upright supports (14) by mounts. The mounts include a stationary mount (60) that is disposed at the upper end (18) of each corner support member (14), a slide mount (62) that is slidably received on an upper leg section (15) of corner support member (14), floating mounts (64, 65) which define a connector that joins a pair of scissors units (40), and upper and lower mounts (66, 67, 68 and 69) that connect internal scissors units (52). Each of these mounts have a plurality of socket openings that receive scissor bars (41 and 42) which connect the structural components of the framework (11). The mounts are noncompressive allowing the scissor units (40) to freely pivot while resisting lateral and torsional deflections.</p> |
