AI Technical Summary

Benefits of technology

The present invention improves the stability and balance of walking up and down a spiral staircase by increasing the surface area on both feet while also allowing for equal support for each foot's legs. This makes it easier for people who are more stable at different levels of their body than they could otherwise have had difficulty navigating through them. Additionally, the design ensures there is enough space between the two feet without making them too bulky. Overall, these technical improvements improve the functionality and usability of the walker.

Problems solved by technology

The technical problem addressed in this patent text relates to improving the design of spiral stairs, particularly in smaller spaces where they may have difficulty reaching up or down the staircase due to limitations such as lack of space or instability caused by the small size of the steps.

Embodiment Construction

[0018]In accordance with the accompanying drawings, the invention relates to a spiral staircase. It comprises a central supporting element (1) and a plurality of steps (2), which are connected to the supporting element (1) at a first end (2a). In particular, as shown in FIGS. 2 and 4, it comprises two types of steps (21, 22), where a first type of step (21) is substantially “L”-shaped and a second type of step (22) is substantially arrow-shaped. They are positioned along the staircase (10) in an alternating fashion, as shown in the detail in FIG. 3.

[0019]The first type of step (21) comprises at least one projection (21a) and one recess (21b) which complement at least one projection (22a) and one recess (22b) of the second type of step (22). The projections (21a, 22a) and recesses (21b, 22b) contribute to forming on the steps (21, 22) treadable portions (21c, 22c) which are separate from portions (21d, 22d) that are not strictly necessary for achieving the advantages which the invention
