Traditional portable balconies—often used for pets like cats—are clunky, difficult to install, and pose a safety risk during assembly. Most require several screw clamps, making setup complicated and increasing the chance of accidental falls before securing, which can cause injury or damage.
The Core Innovation
This invention introduces a simplified, safer, and tool-free balcony that attaches directly to an open window frame. It features a lightweight platform (plate), a mechanical support below, and a clever tensioning system that braces the balcony securely between the inner and outer parts of the window without screws or damage to the building.
The Inventive Step
What makes this balcony unique is its integrated tensioning system that uses either a rope-and-ratchet or a locking bar mechanism to securely clamp the balcony in place with a single motion. This eliminates the need for multiple clamps or tools. Flexible, comb-like support legs adapt to any window frame shape, while telescopic stabilizers anchor it firmly inside the window, forming a secure, closed frame.
Key Benefits

Broader Impact
This user-friendly balcony enables city dwellers, renters, or pet owners—especially those without permanent outdoor space—to enjoy safe, temporary outdoor access. Its lightweight, reusable design avoids structural modifications and promotes safe use, portability, and sustainability through simplified materials and universal compatibility. It also broadens accessibility to outdoor exposure for small animals and improves urban living quality.
