     BACKGROUND  
     1. Field of the Invention 
     This invention generally relates to tents, canopies and multi-purpose structures. In particular, to tents, canopies and structures that are easily collapsible and portable in a variety of shapes and sizes for play, shade, education and privacy. 
     2. Prior Art 
     Play structures, tents and canopies are well known in the prior art. Typically tents, canopies and play structures have been used indoors in residences and educational facilities and outdoors in backyards and in nature generally used to enclose or cover the entire human body for play and sleep. These tents assume various colors, patterns, and configurations and have multiple purposes such as play, education, shelter and sleeping. People have enjoyed tents and collapsible structures for years and although tents in general and children&#39;s play tents in particular are known in the art, there are currently no tents, canopies or play structures for use while seated and confined to the interior of a vehicle and other modes of transportation such as planes, trains, buses and automobiles. 
     There are currently no tent like products or canopies available that can be used in conjunction with seat belts and child restraints while a user is seated in a transportation vehicle. Current products don&#39;t provide breakaway panels for quick access to the occupant. Structures with varying degrees of enclosure providing an un-obstructed view for use in a vehicle are unavailable. Canopies that extend over and around a seated occupant to provide shade and protection from the sun are unavailable. Therefore, there is an unresolved need for a tent, canopy, structure and the like that comprise means for use while a child is seated, most likely restrained and traveling that offers a play environment, educational environment, privacy and protection from the sun. 
     SUMMARY OF THE INVENTION 
     The disadvantages of the prior art are overcome with the present invention which reflects the desirability of providing children with the opportunity to continue playing inside a tent, structure while seated during travel. The popularity of tents and play structures is well known in the prior art, children like to be covered, inside something like a tent or structure. Children spend a great amount of time traveling in various types of transportation vehicles where they are confined to their seat, in child restraints and seat belts. The present invention enables children to be inside a structure while seated, traveling and confined to a seat with a seat belt or child restraint. Kids can continue the fun, play and imagination playing inside a structure while they are traveling, confined to a seat without obstructing the view of a driver in an automobile or impacting other passengers in other forms of transportation. 
     The present invention adds additional benefits beyond play; it also provides the occupant with privacy, protection from the sun and defines personal space. Prior art provides occupants with shade during travel with panels attached to the window, which provides protection on the sides. The present invention, with use of front and side panels, can provide protection from the sun when the sun is entering from the front windshield, driver side window and front passenger side window when used in automobiles. With the present invention, the occupant has the choice of varying degrees of enclosure providing varying degrees of protection from the sun regardless of where and how the sun is entering the transportation vehicle. 
     Toys, of any size, often pose a problem with regards to use while traveling because they tend to be bulky, difficult to transport and take up space. There are plenty of toys and activities on the market for use while traveling; however, there is currently not a product that combines the fun and enjoyment of a tent, canopy or structure meant or designed to be used while seated during travel in a transportation vehicle. 
     The tent structure of the present invention generally comprises flexible panels of thin material joined together to form an enclosure. The walls made of a light material such as mesh or rip stop to ensure good ventilation and stability. The ceiling generally comprises a lightweight material such as netting, mesh, rip stop or the like to ensure ventilation and an unobstructed view through the top of the structure. Some embodiments of the structure are self-erecting shelters that include a structural frame made of a flexible resilient steel, metal, plastic material or the like are attached to the panels of the walls and ceiling to keep its shape and stability. Other embodiments of the structure are canopy like and can be attached to seats, windows or the like to create a structure and maintain its shape and stability. The structures can be folded and twisted and put into a small accessory bag when not in use for convenient transport. 
     The current invention is designed to be used with child restraints and car seats. Panels are designed to offer quick release options so the structure can be removed quickly from the occupant in the event the child needs to be accessed quickly. Structures with top panels are designed with netting or specific shaping to ensure the view of the driver and/or operator are not obstructed. Structures with bottom panels are open or have crisscross shape to provide maximum ventilation and comfort while the occupant is seated on the structures bottom panel. Canopy type structures can be used with a single panel and users can determine the degree of enclosure they experience by adding optional side and front panels to the top. Structures can be used in captain seats, bucket seats, bench seats and the like with options for single occupants or multiple occupants. Structures have portals to allow access to doors and windows and entry and exit. 
     The preferred tent structure is comprised of a front portal for entering and exiting the structure interior, side portals for easy access to car doors, passengers and/or objects outside the structure, a rear portal for use with child restraints/seatbelts and assist with ventilation and an open or crisscross bottom panel attached to the four walls for added stability. A structure for use in an automobile must not obstruct the view of the driver and/or prevent use of protective restraints. A structure for use in a plane, bus or train must not impede the space of other passengers. 
     The structure can mimic various shapes and sizes and may be used with accessories. Toggle loops can be attached in various areas in the structure to facilitate the addition of accessories containing toggles that can be attached to the structure by inserting the toggles into the toggle loops. Side panels, ceiling panels, window panels and door panels can be added to modify the structures appearance, the experience of the occupant and the use/purpose of the structure. 
     Toys, lights and pockets that can be used for storage of various items such as music devices, games, candy, crayons and the like can be added to the structure to change scenery, increase options for play and creativity. Additional panels can be added to the ceiling, sides and front to offer different decorative markings, scenery, create personal spaces and provide shade. For example, the main structure may be of a solid color; however, additional panels can be added that adds an ocean scene, forest scene or the like. Special lighting accessories with a single light or string of lights can be added to the interior, attached through toggles and toggle loops to maintain functionality and use if the interior structure gets too dark.
