Claim Text:
1. A folding door adapted to be attached to a door jamb having a forward door jamb, a header, and a rear door jamb comprising: a plurality of mini slats adapted to be hung vertically from the door header via a hanging channel track attachable to the header, each mini slat being horizontally coupled together such that the plurality of mini slats form a flexible folding door panel, said folding door panel adapted to substantially span and enclose a space between the forward and rear door jamb, said flexible folding door panel having a forward end near the forward door jamb and a rearward end near the rear door jamb; said folding door panel defining, in series, bounded vertical plane door segments interposed between folding seam door segments; each bounded vertical plane segment having a first subplurality of mini slats maintained in a substantially single vertical plane by a top binder; each folding seam segment having a second subpluratity of mini slats which establish the folding panel seam segments of the folding door; said seam segments being intermediate said plane segments; the forward end of said folding door panel having a forward edge segment adapted to be adjacent said forward door jamb, said forward edge segment having a door closure element; a forward jamb edge piece adapted to be fixedly attached to the forward door jamb, said forward jamb edge piece having a complementary closure element adapted to cooperate with said closure element on said forward edge segment permitting said folding door panel to open and close on said forward door jamb; said folding door panel having a rearward edge piece adapted to be attached to the rear door jamb; a plurality of caster assemblies movably disposed in said hanging channel track, a respective caster assembly attached to a corresponding top binder; each caster assembly including: said depending caster stem extending through said top binder aperture such that said lower stop is below said upper surface of said top binder to capture the stem and the caster assembly atop said top binder; said stem permitting three dimensional movement of said vertical plane segments with respect to said hanging channel track; wherein each caster assembly includes: an axis extending between the at least two wheels which wheels rotate about the axis, said axis running through a hub, said hub having depending legs which legs define a ring-like member; said hub legs defining an upper stem element carrying said low friction interface; a lower stem element having an upper stop disposed above said ring member, said lower stem stop disposed at the lower terminal end of said lower stem, below said upper surface of said top binder; the lower caster stem element extending through said ring and through said top binder aperture such that said upper stop is above said ring member and lower stop is below said upper surface thereby permitting vertical movement of the caster assembly with respect to said top binder.
