A claim says the following:
"a pair of folding frame units, each folding frame unit having a first end and a second end, the first end of each folding frame unit being pivotally connected adjacent the rear end of the upper portion and the opposite end of each folding frame unit being pivotally connected adjacent the rear end of the lower frame member,
each folding frame unit having a pivot point such that the folding frame unit is foldable from an extended position to a collapsed position allowing the upper frame member to rotate towards the lower frame member and thereby fold the trailer into a compact position;"
I am replacing the pivot point with a resilient member (torsion spring) that allows the folding frame unit to fold the same way. Would my resilient member be considered a pivot point and infringe on the claim.
I studied the patent and file history. There is nothing to expand the definition of the pivot point.
Thank You,
