1. An in-line skate assembly, comprising:
a frame having a plurality of receivers each having a proximate end and a distal end; a spring cap positioned in each of said plurality of receivers at said proximate end of each receiver; a sliding collar positioned in each of said plurality of receivers, wherein an outwardly extending flange is disposed on a proximate surface on each of said sliding collars, and wherein a distal surface on each of said sliding collars includes an aperture; a ball positioned in each of said sliding collars, wherein at least a portion of said ball is exposed through said aperture on each of said sliding collars; a locator disk positioned within each of said sliding collars and located on a side of said ball opposite said aperture on each of said sliding collars; a spring positioned in each of said plurality of receivers, said spring having a first end and a second end, wherein said first end of said spring interfaces with each said spring cap, wherein said spring extends into said sliding collar, and wherein said second end of said spring interfaces with said locator disk such that said spring exerts a force on said locator disk, which in turn exerts a frictional force on said ball, which biases a portion said ball against said distal surface of said sliding collar; a retainer with an inwardly extending flange on a distal surface of said retainer, wherein said retainer operatively interconnects to each of said plurality of receivers; wherein each of said sliding collars has a first position of use wherein said inwardly extending flange of said retainer is selectively engaged with said outward extending flange of said sliding collar; and wherein each of said sliding collars has a second position of use wherein said ball is in contact with a surface and said ball is forced into each of said plurality of receivers. |
