Jigsaw puzzle accessories

[4] In the late 1980s, Falcon Games in England applied for a trademark, and on 4th of August 1989 their self-explanatory Jigroll name was registered (UK Patent Office Reference 1318441).

Sizes required for different piece counts are as follows: The major problem with stand alone construction trays is that they cannot be packed away and stored with a part-assembled jigsaw.

Portapuzzle obtained a registered trade mark and international patents for Manchester-based company Parker Hilton Ltd. approximately four years after Falcon Games purchased the patents for Jigroll, a product invented by Leslie Pratt.

When closed up, the flock-backed lining on either side of the case and the "velcro" fasteners exert enough pressure to keep the jigsaw pieces in place.

This invention is generally considered to be a safer way of keeping pieces in place but involves more material and assembly labour than a Jigroll, and is consequently more expensive.

Traditionally (especially in Japan) jigsaw puzzles that are hung on a wall are glued onto a backing board.

Ultimately the entire sandwich is held together with straps that are provided and then the whole is stored in an outer cardboard case.

This accessory may be used by dedicated enthusiasts or at schools and clubs, where there is a requirement to keep and display many completed puzzles.
