the detailed description set forth below in connection with the appended drawings is intended as a description of exemplary embodiments and is not intended to represent the only forms in which the embodiments may be constructed and / or utilized . the description also sets forth the functions and the sequence of steps for constructing and operating the exemplary embodiments in connection with the illustrated embodiments . however , it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of this disclosure . exemplary embodiments disclosed herein may include a simple , wind - driven , generally non - mechanized action toy vehicle that does not require batteries or other power sources . the methods and systems disclosed herein may also provide an amusing play action wherein the user can actively walk or run along with the system and enjoy active exercise . the user and observers may enjoy its rolling travel and animated sail action , such as a rider assuming various reactive postures , and graphic effects . in addition to the animated action of the sail adjusting to the wind , various parts can be further animated . for example , the entire sail can be sprung , sail / body segments can be jointed and sprung , and the entire vehicle can be animated using , for example , eccentric wheels . the play action and value may also be enhanced by the graphics and configuration of the system in the forms of a skateboarder , roller skater , racing

in the form of a fin or tail in this embodiment . as shown , shapes may be removable from sheet 12 and may include graphics and / or other configurations such that they may be easily assembled into a three dimensional vehicle . in this embodiment , components 14 ( not shown ) may include an axle , a sail coupling adapter , as well as other adapters and piece parts that may facilitate coupling the shapes together to form a three dimensional vehicle . alternatively an axle may be configured with the body portion , as desired . sheet 12 may be made from a material such as expanded polystyrene , polyethylene , relatively thin cardboard , nerf - type foam material , or other generally lightweight , durable , and inexpensive material , but may be made from other materials , as desired . the shapes may be die cut or “ kiss - cut ” where the resultant sheet may be packaged and sold intact . furthermore , they may be die cut to easily be removed from sheet 12 by a user , such as a child . however , some parts may be removed from the sheet during manufacturing , and placed within the package so as not to require them to be punched out by the user prior to assembly . wheel 30 may include a bushing 34 which may facilitate the wheels rotating about an axle more easily to allow the system 10 to roll with little force acting upon it , such as a slight breeze , among others . furthermore the bushings 34 may spread the dynamic load of the system to allow the use of low mass material , otherwise not structurally suitable , for the wheels . with this configuration a vehicle system may be produced inexpensively and may be easily put together by a child and used as a toy . this type of system may be very inexpensive to manufacture and distribute , such that the price may be relatively low , which may make user &# 39 ; s more likely to purchase multiple systems , or advertisers to give them away . body portion 26 may include an orifice 36 and a slot 38 . orifice 36 may be configured to allow a sail coupling adapter to fit therethrough . furthermore , a bushing may be included in orifice 36 to facilitate the movement of components , as well as add to the durability and longevity

relatively small , lightweight , inexpensive , easy to assemble child &# 39 ; s toy may be made such that a user , such as a child , will be able to construct and use the vehicle relatively easily . the relatively small package , as a wrapped / backed single sheet or as a box or such containing other parts , may make it very easy to ship numerous amounts of the article of the system such that it will not take up a lot of space in packaging , shipping , storage , and display , thus making the system more attractive to retailers and users . the inexpensive nature of the system may make the system attractive to buyers as it may be easily replaced if broken , or many systems with the same or different graphics and designs may be purchased for or by a child . therefore , these systems may configured and manufactured in a variety of sizes , including sized and used as trading cards , and the like . furthermore , many themes may be utilized that may appeal to potential purchasers as a
