Abstract
Abstract A jigsaw puzzle assembly and storage apparatus is disclosed. The apparatus includes a ferromagnetic base portion preferably contructed including a thin layer of tin or steel. The base portion includes at least one beveled edge which permits a partial assembly or an entire puzzle to be shifted intact up the beveled edge and onto the base portion for storage. A flexible magnetic cover sheet is hingeably coupled to the base portion along one edge and the magnetic attraction between the entire surface of the ferromagnetic base portion and the magnetic cover sheet serves to hold a plurality of jigsaw puzzle pieces fixedly mounted in a desired relationship during horizontal or vertical storage. A preferred embodiment of the present invention includes a set of folding legs disposed on the lower surface of the base portion which permit the base portion to be utilized as a freestanding work station.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
An apparatus useful for assembling and storing at least one jigsaw puzzle comprising: a ferromagnetic base portion for the assembly of component jigsaw puzzle pieces adapted to hold a completed jigsaw puzzle; a flexible magnetic cover sheet overlying said base portion and hingeably coupled to said base portion along at least one edge thereof, said cover sheet adapted to impart a compressive force upon said component puzzle pieces due to the magnetic attraction exerted between said ferromagnetic base portion and said magnetic cover sheet; and a plurality of folding support members attached to the bottom of said base portion and adapted to support said base portion in a substantially horizontal position.
Claim 2
Independent Claim
111 words
An apparatus useful for assembling and storing at least one jigsaw puzzle comprising: a ferromagnetic base portion for the assembly of component jigsaw puzzle pieces adapted to hold a completed jigsaw puzzle; a flexible magnetic cover sheet overlying said base portion and hingeably coupled to said base portion along at least one edge thereof, said cover sheet adapted to impart a compressive force upon said component puzzle pieces due to the magnetic attraction exerted between said ferromagnetic base portion and said magnetic cover sheet; and a plurality of folding support members attached to the bottom of said base portion and adapted to support said base portion in a substantially horizontal position.
