US Patent 10351196 Bicycle attachment for carrying a folding chair

A foldable-chair carrier for a bicycle includes a frame that defines a plurality of generally planar, inclined chair-supporting surfaces over the rear wheel of the bicycle. The frame includes a pair of enlarged hooks at the forward, upper portion of the frame, with the hooks being arranged to receive opposite ends of one of the structural tubes of the chair in its folded configuration. The hooks may be sufficiently large to receive two or more of the folded chairs, in a stacked array. The hooks are configured so that even if the bicycle is running on uneven ground, the chairs will be unlikely to be thrown from the frame even in the absence of supplementary tie-downs.
