  • the present invention relates to portable working surfaces, and more particularly to a desktop table having a magnetically attached, removable mat capable of temporarily, magnetically holding design elements in place.
  • Scrapbooking is a way of preserving personal and family memorabilia in the form of photographs and printed media in decorated albums called scrapbooks.
  • People have probably been scrapbooking since printed material became available to the average person.
  • Some of the earliest and most famous American scrapbookers include Thomas Jefferson and Mark Twain. Mark Twain, or rather, Samuel L. Clemens, received US patent no. 140,245 for his invention of an "Improvement in Scrap-books", the contents of which are hereby incorporated by reference.
  • Modern scrapbooking has evolved into a social hobby in which attractive displays of photos, text, journaling and memorabilia are created, typically using patterned and colored background papers and a host of so-called embellishments.
  • the basic materials used in scrapbooking include background papers that are typically 12 inch square or 8!/2Xl l inch pages and may be printed or cardstock paper. Recently new, smaller album formats have become popular, including 6, 7 or 8 inch square formats.
  • Other materials include photo corner mounts or some other means of mounting photos such as adhesive dots, photo mounting tape, or acid-free glue, scissors, a paper trimmer and art pens or archival pens for journaling
  • More elaborate designs require more specialized tools such as die cut templates, rubber stamps, craft punches, stencils, inking tools, eyelet setters, heat embossing tools and powders and personal die cut machines.
  • Embellishments include stickers, rub-ons, stamps, eyelets, brads, chipboard elements in various shapes, alphabet letters and ribbon.
  • the use of die cut machines is also increasingly popular as in recent years electronic die-cutting machines, similar to printers, that can be connected to one's computer to cut any shape or font have become available.
  • scrapbooking is popular for the strong social network that it can provide.
  • Hobbyists known as “scrappers” or “scrapbookers,” get together and scrapbook at each other's homes, local scrapbook stores, scrapbooking conventions, retreat centers, and even on cruises.
  • the attendees share tips and ideas as well as enjoying a social outlet.
  • Crops typically last about 12 hours, though some can be multi-day affairs. Attendees at crops typically have limited space because of the desire to accommodate as many scrappers as reasonably possible. There is, therefore, a need for a structure that allows a scrapper to ergonomically assemble and adjust scrapbook pages while having a relatively small footprint on the working surface to allow space for scrapbook materials.
  • the invention provides a portable work structure for designing and viewing scrapbook layouts that is ergonomic to use.
  • the invention includes a tabletop containing magnets to which a layout mat may be removably attached.
  • the layout mat is preferably a ferromagnetic sheet on which the scrapbook layout can be held in place by removable magnets.
  • the tabletop preferably includes a foldable support to allow the layout to be viewed at an angle and to reduce the desktop table's footprint on the working surface.
  • the surface of the magnets in contact with the layout mat are proud of the tabletop surface, i.e., they are raised slightly above the tabletop surface.

Abstract

L'invention concerne une structure de travail ergonomique portable permettant de concevoir et de visualiser des maquettes d'albums. Le dispositif selon l'invention comprend un plateau de table pourvu d'aimants avec lesquels une maquette peut être fixée amovible. La maquette est de préférence une feuille ferromagnétique sur laquelle une maquette d'album peut être maintenue en place au moyen d'aimants amovibles. Le plateau de table comprend de préférence un support pliable permettant de visualiser la maquette selon un certain angle et de réduire l'empreinte de la table-bureau sur la surface de travail. Pour maintenir fixe la maquette sur la table de bureau pendant l'utilisation, la surface des aimants en contact avec la maquette est légèrement surélevée par rapport à la surface du plateau de table.
