Modular furniture with tool free assembly

US-10905245-B2 covers a modular furniture system that assembles without tools through integrated, mating connectors built directly into the furniture modules. Grounded in claim 1, the invention is a modular furniture piece comprising a first module carrying a plurality of "first integrated connectors" selectively positioned on it, and a second module carrying a plurality of "second integrated connectors." The key limitation is the connector geometry and registration: the connectors are configured so that when the two modules are placed in their assembled orientation, the first connectors register (align) with the second. Specifically, the first integrated connector is a "longitudinal insert slide portion" extending outward with opposing ends, while the second is a "longitudinal insert retainer" extending outward with an open end, such that the slide portion is received within the retainer. In plain English, this is a slide-and-retain coupling mechanism — pieces interlock by sliding one extruded rail into a matching channel — so a consumer can join modules (a chair, sofa section, or cabinet body) by hand rather than with screws or hardware.

The patent is assigned to Noble House Home Furnishings LLC, with named inventors Venkataramu Bangalore, Zachariah Dannett, and Jin Yap Chin. It was granted in 2021. The CPC classification spans A47C (chairs and beds), A47B (furniture and cabinets), and F16B (fasteners), consistent with the slide-rail joining mechanism applied to seating and casegoods. The family is 8 members across 5 countries, indicating moderate, deliberate international prosecution rather than a single-jurisdiction filing — a sign the assignee intended to protect the design in multiple markets. The patent has 4 forward citations. For a 2021 grant in a mature, crowded furniture-assembly space, a low citation count is unsurprising and is more reflective of the patent's recency and the field's age than of irrelevance.

Where this patent stands: This is a focused, product-oriented refinement rather than a foundational anchor in the modular-furniture field. The broad concept of tool-free modular furniture with integrated connectors predates it by decades (see the 2002–2007 filings below), so the patent's value lies in the specific slide-portion/retainer coupling geometry, not in claiming the category. The existence of a sibling — US-11771232-B2, sharing the identical title and assignee — indicates Noble House built a small portfolio cluster around one product line, suggesting this underpins a commercial flat-pack or knock-down furniture offering. Relative to the field's heaviest hitters in seating modularity (The Lovesac Company, SAC Acquistion), Noble House is a smaller player here protecting a particular connector mechanism rather than competing on citation-weighted foundational IP.

The surrounding space is tightly clustered and mature, dominated by furniture-specific classifications rather than general engineering. Among the citation-ranked TOP_ASSIGNEES, The Lovesac Company (4 patents, 95 citations) and SAC Acquistion LLC (2 patents, 155 citations) lead on modular seating, with Valinge Innovation AB (2 patents, 101 citations) prominent in mechanical joining and Steelcase and Teknion representing the contract-furniture side. Notably, Noble House itself is the assignee on two of the nearest patents (the subject and US-11771232-B2) but does not appear in the citation chart — its filings are too recent and lightly cited to rank by impact, which the citation-weighted ordering under-rewards.

The closest related patents:

• US-11771232-B2 — Modular furniture with tool free assembly (Noble House Home Furnishing LLC · 0 citations · 2-member family) — the assignee's own 2023 sibling sharing the identical title; a continuation-style extension of the same product line and strategic IP the citation-weighted score under-rewards given its recency.
• US-9615663-B2 — Modular tool-less furniture (Clark Evan Davis · 22 citations · 2-member family) — directly on point, claiming tool-free modular assembly; the closest prior independent expression of the same concept the subject patent refines.
• US-9506489-B2 — Connectors used in modular furniture system (Kenneth H Ko · 28 citations · 2-member family) — focuses specifically on the connector mechanism for joining modules, the precise element the subject patent's slide/retainer geometry addresses.
• US-7213885-B2 — Modular furniture assembly (SAC Acquistion LLC · 80 citations · 43-member family) — a foundational, heavily-cited filing with an unusually large 43-member family, signaling aggressive international protection and a likely anchor for the modular-seating segment.

The technology concentration confirms how clustered this field is: Furniture & Cabinets (A47B) appears at 250× the corpus baseline, with Chairs & Beds (A47C) at 168.8× and Fasteners (F16B) at 88.3× — the surrounding result set is densely packed around exactly the seating/casegoods/joining intersection the subject patent occupies. The space is commercial rather than academic (no universities lead the nearest patents), so freedom-to-operate considerations center on competing furniture makers and connector specialists rather than institutional licensing.
