Modular staircase system and kit for erecting a staircase

Abstract

The present invention relates to a novel method and modular assembly for producing a staircase. The modular staircase allows one with little to no skill to quickly and easily order and install a modular staircase at reasonable cost with no specialized technical skill necessary.

Field of the Invention[0003]The present invention relates to staircases and their fabrication for use on a commercial or residential site. More particularly the present invention relates to a staircase system which is pre-configured and precision cut to selected specifications, off site, under factory conditions and comes to the installation site in the form of a kit with improved construction and assembly techniques for such modular staircase systems. In at least one embodiment the staircase of the present invention is at least partially curved.[0004]2. Description of Related Art[0005]...

AI Technical Summary

Benefits of technology

[0013]It has been discovered in the present invention that a modular component comprising custom cut pieces with predrilled screw holes can be lined up and assembled in place by the do it yourselfer or other construction person desiring to assemble a staircase but having little skill in the area of such assembly. By cutting the pieces to a specific shape and providing a subtread plate each portion can be installed without the skill and trauma necessary for prior art modular staircase systems.

Problems solved by technology

The actual measurements can be extremely difficult to determine, even by those of great skill in the art, especially in residential construction, because of the use of various floor to ceiling heights, building codes, variation in the thicknesses of materials, errors in wall placements and the general minute inaccuracies introduced into the area around the staircase during construction due to cutting and measuring accuracy limitations.

Cutting errors in the construction of the staircase itself add even further difficulties in constructing a staircase.

The complexity and precision entailed in this conventional staircase fabrication technique renders it, as a general rule, a method only usable by skilled woodworking artisans and not by a general construction contractor.

While each of them has some advantage over fabrication of a staircase in place, each retains much of the complexity at the onsite installation and thus may still not be satisfactory for installation by a contractor let alone a do-it-yourselfer.

While this is good for this type of staircase, it does not address the standard residential curved staircase made with natural products such as wood, lumber, stone, granite or slate.

The stairs and components are slotted and designed to be built up as you go however since the components are standardized they do not take into consideration variations in walls and the like and can easily not fit a given situation.

This modular method relies heavily on non-wooded nontraditional support means and still has the difficulty in adjusting the staircase to size at the location do to the use of non-adjustable metallic pieces.

The amount of wood and alignment necessary for this method makes it almost impossible for someone without a great deal of skill to actually set in place.
