Abstract
This invention relates to a skateboard which includes two footboards with each footboard consisting of a foot platform and a wheel-set which carries two wheels in axial alignment fixed to the underside of the platform, a spacer element for holding the footboards in a spaced relationship and a pivot arrangement having a vertical pivot axis connecting each footboard to the spacer element to enable both footboards to pivot relatively to the spacer element.
Claims15
A skateboard comprising two footboards, each of the footboards including a foot platform and wheel-set which carries two wheels in axial alignment fixed to the underside of the platform, a spacer element for holding the footboards in a spaced relationship and a pivot arrangement having a vertical pivot axis connecting each footboard to the spacer element to enable both footboards to pivot about said vertical pivot axis relatively to the spacer element thereby providing movement of said wheels which corresponds to the movement of said footboards.
A skateboard comprising two footboards each of the footboards including a foot platform and wheel-set which carries two wheels in axial alignment fixed to the underside of the platform, a spacer element for holding the footboards in a spaced relationship and a pivot arrangement having a vertical pivot axis connecting each footboard to the spacer element to enable both footboards to pivot relatively to the spacer element, each wheel set including a wheel body, wheel axles which are fixed to and project from the opposite sides of the body with the wheels being journalled for rotation on the axles, a first pivot pin being attached to the wheel body with its axis in a vertical direction, a support member on the wheel body, a second pivot pin pivotally connecting the foot platform to the support member with its pivot axis normal to the wheel axis, and resilient suspension means between the support member and the underside of the foot platform for holding the platform horizontal, said pivot arrangement being pivotally engaged with the first pivot pin.
A skateboard comprising:
- a spacer element, two footboards, a wheel-set connected to each of said footboard, two wheels in axial alignment connected to each of said wheel-sets, each of said wheel-sets being rigidly connected to said footboards with respect to a vertical axis said wheel sets being pivotally connected to said spacer element and being pivotal about a vertical axis.
A skateboard comprising:
- a spacer element, two footboards, a wheel-set connected to each of said footboards, two wheels in axial alignment connected to each of said wheel-sets, each of said wheel-sets being pivotally connected to said spacer element and being pivotal about a vertical axis, a resilient suspension means wherein each of said footboards is resiliently set off from said wheels allowing limited resilient pivotal movement of said footboards in a direction transverse to an axis of rotation of the wheels of said rolling means, wherein each wheel/set including a wheel body having a slot opening into the interior of said wheel body, two wheel axles being fixed to and projecting from opposite sides of said wheel body, said wheels being journalled for rotation on said axles, a vertical pivot pin contained in said wheel body being concentric with said vertical pivot axis, a pivot arm being connected to said spacer element, said pivot arm having an end projection outwardly from said spacer toward and through said wheel body slot, said pivot arm end having a vertical hole therethrough for receiving said vertical pivot pin and enabling said wheel body and said footboard to pivot about said vertical axis.
A skateboard comprising:
- two footboards, each of said footboards having a wheel-set having two wheels in axial alignment, each of said footboards having a foot platform;
- a spacer element, each of said wheel-sets being pivotally connected to said spacer element allowing said wheel-sets to pivot about a vertical axis relative to said spacer element upon corresponding movement of said foot platform about the vertical axis, each of said foot platforms being resiliently and pivotally connected to said wheels allowing said foot platforms to pivot about a horizontal axis relative to said wheels.
