Definitions

  • the invention relates in general to a table arrangement and particularly to a foldable table arrangement. Even more particularly, the invention relates to table arrangement with a foldable table top.
  • a foldable table that occupies a negligible floor area when it is unused is particularly advantageous in small spaces, e.g. in small compartments in vehicles, trains or aeroplanes and other means of conveyance, but also in small booths, cubicles and rooms or similar within various buildings or other stationary or partly stationary installations such as caravans and trailers or similar.
  • a foldable table that occupies a negligible floor area when it is unused is also advantageous in larger rooms or similar that need a flexible furnishing, e.g. in a room used both as a dining room requiring a number of tables and as a lecture room requiring a plurality of chairs but at the most one or a few tables.
  • the refurnishing of such a room is facilitated by tables that are easy to fold and put away, as well as easy to bring out and unfold.
  • a foldable table occupies a negligible horizontal floor area in a folded position it may nevertheless occupy a considerable vertical wall area or similar vertical surface. This is typically the case if the table top of a floor-supported table is folded in a vertical position and then placed in front of a wall, or if the table top of a wall-supported table is folded towards the supporting wall. The folded table top will then cover a part of the wall surface or area, which Implies that the use of this surface or area for hanging or otherwise arranging objects or functions that should be more or less continuously visible and/or accessible is considerably impaired.
  • the folded table top covers a display unit or similar that is mounted on a vertical wall area or similar, or prevents a display unit or similar from being mounted on the vertical wall area, e.g. a wall mounted television apparatus or similar, since this excludes or at least reduces the possibility of observing the images displayed on the display unit.
  • a vertically folded table top would typically not provide any surface for supporting a display unit (e.g. a television apparatus or a computer monitor or similar), a computer, a telephone and similar, even though modem environments frequently demand such functional units. If a functional unit cannot be supported by the table in its folded position or if the unit Is covered by the folded table it will typically need a separate table or some other separate support. This is a clear disadvantage in small spaces as mentioned above. This is also a clear disadvantage In connection with larger rooms or similar, since a separate table will decrease the flexibility of the furnishing etc.
  • a display unit e.g. a television apparatus or a computer monitor or similar
  • a computer e.g. a computer, a telephone and similar
  • WO 02/082948 relates to a computer table comprising an underframe and a table platform, which is located in the underframe so that it can pivot about a horizontal axis and can be displaced from a horizontal position into an inclined position.
  • a monitor is mounted underneath the table platform, whereby the screen of said monitor can be viewed through the table platform.
  • the monitor is configured as a flat screen, hinged onto the table platform in a pivoting manner, or as a touch-sensitive screen mounted on the pivotable table platform.
  • the computer table permits an ergonomic adjustment for each Individual user and provides optimal working conditions in terms of the available working surface.
  • US 6 601 931 concerns an assembly that is provided for supporting a flat monitor in adjacent but underlying relationship to a preferably window pane equipped, preferably rectangularly-configured aperture, provided in a desk-type working platform.
  • An aperture frame extends about perimeter portions of the aperture.
  • a flat monitor support platform is located beneath but adjacent to the aperture.
  • Joining components extend between and interconnect portions of the aperture frame with portions of the flat monitor support platform.
  • a flat monitor is supportable by the platform with the platform generally suspended from the aperture frame with the aperture frame so positioned in the aperture.
  • the flat monitor viewing screen with the flat monitor so supported is viewable through the aperture.
  • the inclination of the flat monitor viewing screen is adjustable if desired.
  • Various aperture frame structures, flat monitor support platforms, and joining components can be utilized.
  • the invention provides for a foldable table arrangement that can be used both as a display unit (e.g. a television apparatus or a computer monitor) and as a table.
  • a display unit e.g. a television apparatus or a computer monitor

  • a foldable table arrangement according to the above is particularly advantageous in connection with touch screens arranged to provide functions that should be more or less continuously visible and accessible.
  • touch screens can e.g. be used in connection with electronic gaming machines, wherein the invention can be advantageously used as an electronic gaming table for playing table games that are traditionally played in casinos.
