Disappearing Lid Utility Patent Granted on the Rockwell Grill

HUNTINGTON BEACH, CA (February 2021) – Caliber Appliances, makers of award-winning grilling products, proudly announces the utility patent granted by the United States Patent and Trademark Office (USPTO) including the fully retractable “disappearing” lid on the Rockwell by Caliber Social Grill. This grill was designed for David Rockwell of the Rockwell Group, an award-winning cross-disciplinary architecture and design firm, exclusively as an installation for one of Rockwell’s projects. The Rockwell Grill is the world’s first estate-scaled, 360 degree walk around, Social Grill™ and this patent truly makes this product unique.

The feature of the fully retractable patented “disappearing” lid with a special counterbalance mechanism allows for a smooth transition from open to close with ease.  When opened the hood disappears under the cooking element creating a grilling surface that is accessible from all sides. The Rockwell by Caliber Social Grill is designed to foster socializing and is inspired by the act of gathering around the hearth or campfire.  By design, the grill allows guests to stand on all four sides during grilling, and a focal area when keeping food warm while entertaining. 

This grill also offers an Industry exclusive, 20,000 BTU patented Crossflame® Burner for ultra-even grilling plus radiant technology.  The freestanding exterior grill is built from heavy-gauge, powder coated, aviation-grade aluminum and is draped over a custom Brazilian cherry stand that is hand rubbed for a fashionable looking finish.

The Rockwell by Caliber Built-In Social Grill comes standard in 304 Stainless Steel and is available as a 2-burner 42″ model and a 3-burner (a 20,000 BTU infra-red sear burner included) 48″ model for custom/built-in applications. 

Custom RAL colors and wood handle upgrades are also available on freestanding and built-in applications.
