Claim:
A sunshade apparatus for shading a chair, the sunshade apparatus comprising: a pair of vertical support legs, each of the pair of vertical support legs having a top end and a bottom end; a pair of attachment elements, each of the attachment elements being attached to the bottom end of one of the pair of vertical support legs, the pair of attachment elements being adapted for mounting the sunshade apparatus on the chair; a pair of horizontally extending arms, each of the pair of horizontally extending arms having a proximal end and a distal end; a pair of hinges, each of the pair of hinges hingably connecting the top end of one of the pair of vertical support legs to the proximal end of one of the pair of horizontally extending arms such that the pair of horizontally extending arms can pivot with respect to the pair of vertical support legs between a folded configuration and an extended configuration; a locking element that functions to lock the pair of horizontally extending arms in the extended configuration with respect to the pair of vertical support legs; a folding element that joins the pair of horizontally extending arms and folds between a collapsed configuration wherein the pair of horizontally extending arms are adjacent, and a spread configuration wherein the pair of horizontally extending arms are laterally spaced from each other; a flexible canopy element attached to the pair of horizontally extending arms such that the flexible canopy extends between the pair of horizontally extending arms when the pair of horizontally extending arms are in the spread configurations; wherein each of the pair of attachment elements includes a clamp having a first locking portion hingably attached to a second locking portion, and a locking screw for clamping the first and second locking portions around a tubular element of the chair, and wherein the locking screw is hingably attached to the first locking portion and pivots between a closed position wherein the locking screw locking engages the second locking portion, and an open position wherein the locking screw is disengaged from the second locking portion.
