[0026] Note also from FIG. 6 that a circuit board 200 is disposed between the lower body 52 and the assembly of the bottom housing plate 66 and the motor cover plate 92. The circuit board 200 is conventional and contains electronic components which allow the steering motor 70 and the drive motor 90 to be controlled by a user operating the remote controller 190. These include a radio receiver 202 coupled with a programmed microprocessor 204. The microprocessor 204 supplies current to either motor 70, 90 through drive motor control circuit 206 and steering motor control circuit 208 from the battery power supply 67. An antenna 210 allows the radio receiver 202 to receive signals from the remote controller 190.

[0027] With reference to FIG. 7, the first pair of trailer wheels 122 is connected by axle 132, while the second pair of trailer wheels 124 is connected by axle 134. The trailer box 150 is secured to the flat bed of the trailer 120 by the interfit between the vertical ledges 136 extending both up and down from an outer edge of the flat bed of the trailer 120 and the edges around the bottom opening of the trailer box 150. The trailer box 150 is preferably further secured to the flat bed of the trailer 120 by the snap fit of a plurality of protuberances 140 on the ledges 136 into a corresponding plurality of slots 162 in the bottom side edges of the trailer box 150. The trailer box 150 rests upon a horizontal ledge 138 when installed on the flat bed trailer in either the storage configuration 20 or in the play configuration 30. An elongated vertically oriented member 142 extends in both up and down directions perpendicularly from ledge 138. The member 142 helps retain the trailer box sides 156 and 156 against ledges 136, thus helping to maintain engagement of slots 162 with protuberances 140.

[0028] A male connector 126 is fixedly attached to the flat bed of the trailer 120 at an opening 130 near a front portion of the flat bed of the trailer 120. The male connector 126 is generally cylindrical and diminishes in diameter at its upper end proximal to the flat bed of the trailer 120 to define a circumferential shoulder 128. On the depicted left side of the trailer box 150, elongated members 164 and 166 extend from the front wall 158 and the rear wall 160 into the interior of the trailer box 150, respectively, and form slots 172 and 174 between the members 164, 166 and the left side wall 154. Corresponding elongated members 168 and 170 (see FIG. 5) are provided on the right side 156 of the trailer box 150, and form slots 176 and 178 between the members 168 and 170 and right side wall 156. Cardboard panels 112 to which user generated graphics 228 (see FIG. 8) have been affixed may be inserted within the slots 172, 174 and 176, 178, respectively. Alternatively, graphics 228 may be printed on suitable paper and installed within the slots 172, 174 and 176, 178 without use of the cardboard panels 112. Cutouts 180 are provided in the sides 154 and 156 of the trailer box 150. The cutouts 180 facilitate removal of the trailer box 150 from the flat bed of the trailer 120 in both the storage configuration 20 and the play configuration 30. A hole 182 is provided in the top 152 of the trailer box 150 to facilitate manufacture of the trailer box 150. A similar hole 144 is provided in the flat bed of the trailer 120 also to facilitate manufacturing. Cosmetic plugs 184 and 146 are provided to seal holes 182 and 144, respectively.

[0029] In use, the toy tractor-trailer rig may be sold in its storage configuration 20 or alternatively may be sold in conventional packaging, with the tractor and/or remote controller not stored within the storage container 22. Starting from the storage configuration 20, the top portion 150 of the storage container 22 is removed, and male fitting 192 of the remote controller 190 is disengaged from the female connector 58. After the tractor assembly 40 and remote controller 190 are removed from the bottom tray 120 of the storage container 22, the bottom tray 120 is inverted and assumes its vehicle play configuration 30 as a flat bed of the trailer 120. The flat bed of the trailer 120 is pivotally connected to the tractor assembly 40 when the male connector 126 is snapped into place within the female connector 58. If desired, the top portion 150 can be installed over the flat bed of the trailer 120, thereby assuming its play configuration 30 as a trailer box 150. Alternatively, the trailer box 150 may be set aside, and the tractor-trailer rig 10 played with as a combination of the tractor assembly 40 and the flat bed of the trailer 120. After play, the toy tractor-trailer rig 10 may be returned to its storage configuration 20 for convenient and compact storage until the next play session.

[0030] Sides 154 and 156 of the trailer box 150 are transparent and the cardboard panels 112 are intended to support and display cardboard art supplied with the toy vehicle 10 or user printed graphics 228. With reference to FIG. 8, a user 220 may download graphics 228 using his or her home computer 222 via an internet connection 230 to the manufacturer's website located on a server 232. The graphics 228 may be printed on a printer 224 on paper 226 which may then be affixed to the cardboard panels 112 or alternatively simply inserted within the slots 172, 174 and 176, 178, allowing the user 220 to customize the appearance of his or her tractor-trailer rig 10.

[0031] It would be obvious to one skilled in the art from this disclosure that other materials (for example, metal or polyethylene plastic), fabrication techniques (for example, stamping or machining), or other relative proportions of the toy tractor-trailer rig 10 components (for example, a longer cab 14) could be substituted for the materials, fabrication techniques and relative proportions shown in the preferred embodiment of the toy tractor-trailer rig 10 shown without departing from the spirit and scope of the invention.

[0032] Although a wireless remote control vehicle is described as the preferred embodiment, it will be appreciated that the present invention can be incorporated into unpowered toy vehicles as well as powered toy vehicle of various forms including unmotorized vehicles, simply motorized vehicles, other types of remotely controlled vehicles or programmable vehicles. Remotely controlled vehicles may be wired or wireless and wireless control may be by radio, sound, infrared or other light.

[0033] While steerable front wheels with a steering motor are described, steering may be accomplished by independent motors independently driving one or more wheels on separate sides of the vehicle or so-called “J” steering in which a single motor moves the tractor forward and backward and either a transmission or a swinging front wheel axle causes the vehicle to turn when it is driven in reverse.

[0034] It would be further obvious to one skilled in the art from this disclosure that other embodiments of the present invention could be substituted for the toy tractor-trailer rig 10 shown in the figures. For example, a farm tractor could be substituted for the tractor assembly 12 and a farm wagon substituted for the flat bed trailer 16. Or a train locomotive could be substituted for the tractor assembly 12 and a boxcar substituted for the flat bed trailer 16 and trailer box 18 combination.

[0035] One of ordinary skill in the art would further understand that any known steering assembly, such as tank steering using separate motors to independently drive separate wheels, could be substituted for the steering mechanism disclosed herein.

[0036] It will be appreciated by those skilled in the art that other changes in addition to those cited above could be made to the embodiment described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiment disclosed, but it is intended to cover modifications within the spirit and scope of the present invention.
