Ah! You’re likely referring to the “wrought-iron window grilles” (or burglar bars) that have a curved or bulging design at the bottom. This isn’t just for decoration—it actually serves an important purpose!
Why Some Window Grills Curve Outward at the Bottom:
-
Anti-Burglary Feature – The curved design makes it much harder for intruders to get leverage to pry or bend the bars open. A straight, flat grill can be more easily forced apart with tools.
-
Prevents Climbing – The outward curve makes it difficult for someone to use the grill as a foothold to climb up to higher windows or balconies.
-
Structural Strength – The curvature adds rigidity, making the grill more resistant to bending or breaking under force.
-
Aesthetic & Tradition – In some older architectural styles (like Spanish or Colonial designs), the curves were added for visual appeal while still serving a security function.
Bonus Fact:
In some places, building codes require window bars to be operable from the inside (for fire safety), so the curved design may also accommodate quick-release mechanisms.
Did you see this on historic homes or modern security grilles? It’s a clever mix of form and function! 🔒😊
