AI Technical Summary

Benefits of technology

The invention is a staircase design that makes it easier to ascend and descend, providing more stability and balance for users. The steps have a shape that increases the surface area for support, and the landing can have more steps, reducing the riser and creating a similar ratio to straight ramps. The design also allows for flexibility to cover any height, adapting to different plan shapes and directions of rotation. The invention can be made from various materials and colors.

Problems solved by technology

The technical problem addressed in this patent relates to making improvements in spiral staircases where there may be limited space availability, particularly for individuals who have a normal built-in size but find the narrowness of the steps challenging when ascending or descending. Additionally, the spacing of the steps often results in insufficient stable surfaces for the feet, especially when walking downwards. Current solution designs also fail to provide optimal ratios of riser to tread for efficient use of space and favor one foot over another.
