Shell for a portable electronic device with a track adaptor

Abstract

A universal track adaptor system having a shell including a portable device receiving surface arranged for receiving and detachably holding a portable electronic device, said shell further including a track facing surface, a plurality of wheels including a first wheel and a second wheel; a first track adaptor rotatably coupling said first wheel and said second wheel to said track facing surface, said first track adaptor having a specific range of motion, said first track adaptor including an adaptive mechanism operable to adjust a specific width between said first wheel and said second wheel through said specific range of motion, whereby said first wheel and said second wheel can be adapted to interface with a plurality of different sized tracks, as permitted by said specific range of motion.

I claim: 
     
         1 . A universal track adaptor system, said universal track adaptor system comprising:
 a shell including a portable device receiving surface arranged for receiving and detachably holding a portable electronic device, said shell further including a track facing surface;   a plurality of wheels including a first wheel and a second wheel;   a first track adaptor rotatably coupling said first wheel and said second wheel to said track facing surface, said first track adaptor having a specific range of motion, said first track adaptor including an adaptive mechanism operable to adjust a specific width between said first wheel and said second wheel through said specific range of motion, whereby said first wheel and said second wheel can be adapted to interface with a plurality of different sized tracks, as permitted by said specific range of motion.   
     
     
         2 . A universal track adaptor system as recited in  claim 1 , wherein said universal track adaptor further comprises:
 a wheel retracting mechanism operable to move said first wheel and said second wheel between a track engaging position suitable for interfacing said first wheel and said second wheel, and a retracted position.   
     
     
         3 . A universal track adaptor system for interfacing a toy with a plurality of different sized tracks, said universal track adaptor system comprising:
 a base including a toy receiving surface arranged for receiving and detachably holding said toy, said base further including a track facing surface;   a plurality of wheels including a first wheel and a second wheel;   a first track adaptor rotatably coupling said first wheel and said second wheel to said track facing surface, said first track adaptor having a specific range of motion, said first track adaptor including an adaptive mechanism operable to adjust a specific width between said first wheel and said second wheel through said specific range of motion, whereby said first wheel and said second wheel can be adapted to interface with a plurality of different sized tracks, as permitted by said specific range of motion.   
     
     
         4 . A toy train with integral track adaptor system comprising:
 a train module;   a plurality of wheels including a first wheel and a second wheel;   a first track adaptor rotatably coupling said first wheel and said second wheel to said track facing surface, said first track adaptor having a specific range of motion, said first track adaptor including an adaptive mechanism operable to adjust a specific width between said first wheel and said second wheel through said specific range of motion, whereby said first wheel and said second wheel can be adapted to interface with a plurality of different sized tracks, as permitted by said specific range of motion.
