Abstract:

A portable beach chair cover is presented. In exemplary embodiments of the present invention, a portable beach chair cover has a slip-over pouch which slides over the headward or upper portion of a beach or lounge chair, and ties or clasps or other fixations in which the lower or footward portion of the beach chair cover can be affixed to a beach chair. In exemplary embodiments of the present invention there can be a number of pockets hanging off of the sides of the beach chair cover, which can hold objects such as sunglasses, suntan lotion, books, coins, personal digital assistants or portable email devices, and other small devices or objects which a beach chair user would find convenient. In exemplary embodiments of the present invention such pockets can be open, closable via zipper, Velcro or other fastening device, and can have a fold over flap to further secure the objects inside. In exemplary embodiments of the present invention these side-pockets can have tiny locks such as are commonly found in luggage for greater security. In exemplary embodiments of the present invention underneath the footward portion of a beach chair cover there can be a hidden pouch, which can be zippered closed and further secured by means of a small lock. Alternatively it can be affixed by Velcro with a fold over flap or using other known closure mechanisms. Inside this pocket, invisible to someone looking at the beach chair cover in its normal configuration on a beach chair, a user can, for example, place his wallet, cash, valuables and other items. The items will not be visible to a casual observer or passer-by. In exemplary embodiments of the present invention there can be a series of loops sewn into one of the sides of the beach chair cover, for example adjacent to a side-pocket, such that a cord or wire can be run from a device in the side-pocket and run through the loops and up to a user's ear or to a small speaker which can be clasped to the upper portion of the beach chair. In exemplary embodiments of the present invention, the entire beach chair cover can be folded up into the slip-over pouch, and carried by means of a handle attached to the beach chair cover. In exemplary embodiments of the present invention, the beach chair cover can have a foot protector, being a pouch at or near its footward edge.
