Independent Claims Overview
This patent has three independent claims, which define the core inventions protected.
Claim 1: This claim describes a puzzle platform where a main puzzle board and its underlying support structure (reinforcing assembly) are a single, integrated piece. A separate, detachable upper border attaches to the edge of the board using a system of hooks on the border that engage with holes on the board's fixing portion. The reinforcing assembly underneath creates space for at least two drawers.
Claim 16: This claim focuses on a puzzle platform where the board and its reinforcing assembly are also a single unit. The key feature is the mechanism for securing the drawers. The assembly includes at least one "limiting bar" that mates with a "limiting groove" on a drawer. It also includes "drawer holders" with a flexible "bending portion" extending from a reinforcing wall to hold the drawers within their designated space.
Claim 23: This claim details a puzzle platform with a rotating capability. It specifies a main board and its integrated reinforcing assembly built as a one-piece structure. A rotating assembly is attached to this structure. The patent highlights a specific attachment method: the reinforcing assembly has an integrated "coupling portion" with a hole, and a screw passes through the rotating assembly into this hole to secure it. This entire structure also provides space for at least two puzzle drawers.
