Abstract
The present staircases are constructed of modular stringers for the on-site Installation of the staircases in a residential, commercial or industrial setting. Kits for erecting the staircases will include matingly or cooperatively coupling step support units defining the staircase stringers, a set of steps adapted to be mounted thereon, as well as various finishing elements and modules to provide a finished look to the completed staircases. The staircases presented herein include self-supporting staircases, linear staircases, curling or spiralling staircases and adjustable variations thereof. Each kit is designed to provide an easy installation of the staircases while providing for the erection of solid finished staircases.
Claims90
A modular stringer for a staircase, the stringer comprising at least two matingly coupled step support units defining the stringer, said step support units each comprising a main structural body, a first mating structure extending substantially laterally from a first lateral side thereof and a second mating structure extending substantially laterally from an opposing lateral side thereof, said first mating structure of said step support unit being adapted to be matingly coupled with an adjacent second mating structure of an adjacent step support unit such that said adjacent unit is vertically offset therefrom.

A step support unit to be matingly coupled with at least one structurally similar adjacent step support unit such that said adjacent unit is vertically offset therefrom, the unit for the construction of a modular stringer for a staircase, the step support unit comprising a main structural body, a first mating structure extending substantially laterally from a first lateral side thereof and a second mating structure extending substantially laterally from an opposing lateral side thereof, said first structure comprising at least one mating element and said second structure comprising at least one complementary mating element complementary to said mating element of said first structure and vertically offset therefrom.
A kit for erecting a staircase between an upper and a lower structure, the kit comprising at least two modular stringers each comprised of an equal number of step support units defining the stringers and a series of steps adapted to be mounted to said step support units, said step support units each comprising a main structural body adapted to support said steps thereon, a first mating structure extending substantially laterally from a first lateral side thereof and a second mating structure extending substantially laterally from an opposing lateral side thereof, within a same stringer said first mating structure of said units being adapted to be matingly coupled with an adjacent second mating structure of an adjacent unit such that said adjacent unit is vertically offset therefrom.
