Modular staircase system

Abstract

A modular staircase system configured to form a curved staircase, support extremely heavy finishing materials, having higher design tolerances, and can be achieved at a relatively moderate cost. A plurality of stair modules are configured to secure to one another to form a complete staircase system, each which has an elaborate stringer of significant strength and moderate weight configurable to create floating staircases at an affordable cost.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to staircase systems utilized in the building industry.BACKGROUND OF THE INVENTION[0002]A conventional staircase system includes a plurality of ascending / descending steps laterally extending between a pair of stringers, each of the steps include a tread portion and a riser portion. Stairs are expensive due to the high cost of the materials, as well as the skilled labor required to make and construct such systems. The labor can easily exceed the cost of the materials in even the most basic staircase systems. As the complexity of the staircase increases, including designing curves, landings, and floating stair systems, the price exponentially escalates due to the cost of the materials, the wasted materials, and the additional labor.[0003]Staircase systems area complex works of art. Stair owners have unlimited choices of material to cover their stair with. It could be as simple as oak treads, oak riser, oak skirt board...

AI Technical Summary

Benefits of technology

"The present invention is a modular staircase system that can be configured to form a curved staircase, support heavy finishing materials, and has high design tolerances. The system is made up of stair modules that secure to each other, each module having an elaborate framed stringer of significant strength and moderate weight. The stringers are made of steel and can be designed to be curved to extremely tight tolerances and support extremely heavy loads. The staircases designed according to the present invention can realize up to a 40% savings in materials and a 50% savings in labor compared to conventional staircase systems."

Problems solved by technology

Stairs are expensive due to the high cost of the materials, as well as the skilled labor required to make and construct such systems.

The labor can easily exceed the cost of the materials in even the most basic staircase systems.

As the complexity of the staircase increases, including designing curves, landings, and floating stair systems, the price exponentially escalates due to the cost of the materials, the wasted materials, and the additional labor.

With the complexity of building and designing stair systems, many of the stairs are fabricated off site and then transported to the job site and then installed.

In high-end staircase systems, curved stringers are often made from large expensive cold rolled steel.

These metal stringers are extremely difficult to tool given both the tooling tolerances, as well as the variations of the material over temperature.

The longer the stringer, the more likely that tolerances can lead to a staircase that fails to meet the design requirements in its intended location.

Given the extreme pricing of the tooling and the steel stock, it is an expensive task to simply scrap the stringer.

More elaborate designs include multiple landings, which increase the stair complexity and loading requirements.
