Abstract: An apparatus for and method of retaining a beach chair (or other object having metal tubing) on a bicycle (or other wheeled vehicle). The apparatus includes a metal plate, having a hole in its middle, at which it is attached to a bolt extending from the axle of the rear wheel of the bicycle or other vehicle. At one end of the plate is a metallic cylindrical clamp with an interior lining of rubber (or other elastic material). The aluminum tubing of a beach chair may be retained in the cylindrical clamp, to carry the beach chair on the vehicle. The cylindrical clamp has two longitudinal sections, that may opened and securely closed using a lever. There is a notch at the other end of the plate, by which it may be retained on the frame of the bicycle or other vehicle, to prevent it from turning on the axle.

Abstract: A holder for a cooler (or a similar object) on a bicycle (or other vehicle), which preferably is combined with a holder for a beach chair (or a similar object). In the preferred embodiments, the bicycle has a rack behind the seat and over the rear wheel, with a holder fastened over the rack. The holder has a rectangular bottom, an open top, and front, back, left and right walls that are perpendicular to the bottom. The front and back walls are joined by rounded corners to the left and right walls. The holder is suitably dimensioned and configured to retain a rectangular cooler with rounded corners. The holder is preferably made out of rigid, smooth plastic, which will not be deformed by the weight of the cooler, but will have sufficiently low friction with the exterior surface of the cooler that the cooler can be easily removed. Different sizes of holders may be used for different sizes of coolers. The holder may be bolted to the frame, or securely retained by other suitable means.
