Abstract
Abstract A skateboard folding structure is provided having an upper connecting member ( 31 ) pivotally joined to a lower connecting member ( 32 ). The upper connecting member ( 31 ) is formed on a lower end of a handle member ( 21 ). The lower connecting member ( 32 ) is received within a skateboard frame member ( 11 ). A quick release connector ( 4 ) releasably clamps the upper connecting member ( 31 ) and selectively prevents rotation of the handle member ( 21 ) about skateboard frame member ( 11 ).
