Abstract
Abstract A sun shade (10) for mounting to a chair or other furniture comprises a support frame (11) including a lateral tube (21) and vertical tubular legs (12, 13) pivotally mounted to the lateral tube. A central clamp (26) is rigidly mounted to the lateral tube (21) and includes a U-shaped opening (36) for engagement over an upper edge portion of the chair. Outboard clamps (41, 42) are slidably positioned on lateral tube (21) and have U-shaped openings (43, 44) for engagement over side edge portions of the chair. Means (22, 23, 24) are provided for resisting the pivotal movement of the tubular legs (12, 13) relative to the lateral tube (21). A canopy assembly (51) is pivotally mounted to the tubular legs (12, 13) and includes a rectangular frame (52) and a fabric panel (56).
