Definitions

  • the present invention relates generally to a modular tile and modular tile system. More specifically, it relates to a modular tile and modular tile system installed on an existing floor.
  • both types of raised floors namely the architectural and the pieced-together, are installed by skilled tradespersons having special tools, equipment and training.
  • providing adequate support and proper leveling are important concerns.
  • the installation and/or reconfiguration of the conventional raised floor is often costly.
  • work environment elements can not be easily configured and reconfigured with the typical raised floor.
  • raised floors are most often installed in a wall-to-wall configuration, a facilities planner must commit to equipping the entire work space with a raised floor, rather than equipping only that portion with the requirements justifying a raised floor. This fact reduces the utility and adaptability of raised floors to certain work environments, especially those that have a need to equip some work stations one way for some of its workers and some another way for others of its workers. In particular, it would be desirable in some work environments to create platforms of a raised floor to meet the needs within that part of the work environment.
  • the conventional raised floor often lacks specific cabling management capabilities. For example, in some systems, the cabling is not isolated from one another nor managed separately within the floor. This can create interference and noise problems between power, communication, and data cabling.
  • the present invention is directed to a modular tile and modular tile system.
  • the modular tile has a base structure having a generally horizontal portion and four support legs. The legs engage the existing floor and support the horizontal portion above the floor thereby providing a lower chamber between the existing floor and the horizontal portion.
  • the tile also has four upper column members and a cover supported by the upper column members a distance above the horizontal portion thereby creating an upper chamber.
  • a system of tiles have at least four modular tiles arranged so that a corner of each of the tiles meet at a common point.
  • the tiles comprise a base structure having a generally horizontal portion, a connecting point at each corner, and four support legs engaging the existing floor thereby creating a lower chamber.
  • the lower chamber is adapted to receive cabling.
  • Four upper column members extend above the horizontal base structure.
  • a cover is supported by the upper column members and creates an upper chamber adapted to receive cabling.
  • a tile connect engages adjacent connecting points to releasably connect the modular tiles.
  • a system of tiles on which a work environment is configured is provided.
  • the work environment includes elements such as panels, screens, work surfaces, storage cabinets, ramps, and lights.
  • the system has a plurality of tiles arranged across the existing floor to create a platform.
  • Each tile has a bottom portion and a top portion.
  • the top portion includes an array of apertures adapted to receive a protruding portion of an indexing element associated with a work environment element.
  • a system distributes electrical power in a work environment.
  • the system includes an electrical connector receiving electrical power from an power source.
  • a first modular tile has a circuit defined by a first and a second conductor. The first circuit receives the electrical power from the electrical connector.
  • a second modular tile has a circuit defined by a first and a second conductor.
  • a modular tile connect electrically connects the first circuit with the second circuit such that the electrical power received by the first circuit energizes the second circuit.
  • cabling is meant to refer to cables and wires including power, data and utilities servicing a work environment and corresponding work environment elements.
  • work environment element is meant to include elements such as work surfaces, panels, screens, storage cabinets, ramps and the like.
  • Work environment elements could also include powered devices such as computers, lights, sound booms, powered panels, screens, work surfaces and the like.
  • the preferred present invention is modular in that it is configurable and can be quickly connected and re-connected.

Abstract

Cette invention se rapporte à une dalle de plancher modulaire et au plancher modulaire correspondant. Ladite dalle comporte une partie horizontale, des éléments colonne supérieurs et quatre pieds de support qui entrent en contact avec le plancher de manière à constituer une enceinte inférieure. Un revêtement supérieur, qui est supporté par les éléments colonne supérieurs, crée une enceinte supérieure permettant de loger des câbles. Ces dalles modulaires possèdent un point de connexion au niveau de chacun de leurs coins. Un plancher de telles dalles modulaires est constitué d'au moins deux dalles modulaires agencées par rapport à un point commun. Un organe de connexion de dalles relie de manière libérable les dalles modulaires dans une structure de plate-forme. Selon une réalisation de l'invention, des éléments d'un environnement de travail sont disposés sur la plate-forme de dalles modulaires. Chaque dalle modulaire comporte un ensemble d'ouvertures conçues pour recevoir une partie en saillie d'un élément d'indexage associé à un élément de l'environnement de travail. Dans une autre réalisation, le plancher de dalles modulaires sert à la distribution de l'énergie électrique. Un connecteur électrique transmet l'énergie électrique à un premier circuit de dalle modulaire défini par un premier et un second conducteurs. Un organe de connexion des dalles modulaires relie électriquement le premier circuit à une seconde dalle modulaire.
