Smart Summary: Stairsavers are brackets designed to fix old stairs that are becoming weak. They are shaped like a "U" and made from strong half-inch thick steel. These brackets attach to the existing wooden parts of the stairs to provide extra support. If needed, they can be taken off later and reused to create new stair supports. This makes them a practical solution for repairing stairs without permanent changes. 🚀 TL;DR

Abstract:

Stair savers is a u shaped bracket for securing old steps where the original wooden stringer is failing. It is made of solid half inch thick square mild steel drilled in two planes and reaching from the continues part of the stringer to the steps and riser. As stair saver is made of solid steel it can be removed at a later time and used to make new stringers.

BACKGROUND OF THE INVENTION

Owning buildings with older outdoor stairs, we've long looked for a solution to this problem. Wooden stringers are end-grain and won't hold a screw and the triangle wants to break off with the grain anyway, this makes the steps warp and rock back and forth.

BRIEF SUMMARY OF THE INVENTION

Stair Saver screws into the continuous part of the stringer and up into the step and riser. eliminating the triangle and locking down the stairs and riser. These are solid ½ inch square steel bars, Additionally, if you ever want to replace the stairs entirely just re-use them to make new stringers.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

FIG. 1A depicts a staircase with stair saver installed. The short arrows denote holes for securing screws along with labeling for steps, stringer and risers.

DETAILED DESCRIPTION OF THE INVENTION

Stair savers (FIG. 2A) is a U shaped bracket made from solid half inch by half inch square mild steel. Having two mechanical bends with the hight of the long leg at 11.75 inch, 6.75 inch on the short leg and 9.75 inch across the width. There are 10 holes 13/64″ of an inch drilled for securing screws, two on each leg in a perpendicular plane to the stringer, two on the long leg in a parallel plane as the stringer to secure the riser and 4 holes in a parallel plane as the stringer to secure the steps. This bracket is unique in that: 1. It connects the continuous grain of the stringer to the steps and riser. 2. It adapts to whichever rise/run slope your stairs are at. 3. Being made of solid metal it is not affected by corrosion, can be removed later and repurposed to make new stringers and it's strength easily exceeds what is needed.

Claims

1. Stair savers connects the continuous grain of the stringer to the steps and riser.

2. Stair savers adapts to whatever rise/run slope your stairs are at.

3. Stair savers are made of solid metal and largely unaffected by corrosion.

4. Stair savers can be removed later and repurposed to make new stringers

5. As stair savers are made of solid metal, it's strength easily exceeds what is needed even while drilled in two separate planes.
