Why Are Some Window Bars Curved at the Bottom?

Have you ever noticed that some window bars are not completely straight?

Instead of running directly from the top of the window to the bottom, some metal bars curve outward near the lower part of the window.

At first glance, this unusual shape may seem purely decorative. However, curved window bars can serve several practical purposes, depending on the building, the location of the window, and the way the structure was designed.
