Definitions

  • the present invention relates to the field of office furniture and workspace management systems. More particularly, the invention relates to a worksurface system having a height-adjustable worksurface and a convenient storage member.
  • a worksurface is a surface, typically horizontal, that a person can work on.
  • An example of the most common type of worksurface is a simple table or desk.
  • Another type of worksurface system is provided by cantilevering a worksurface off of the partitions or wall units within a workspace management system.
  • Prior storage compartments such as those disclosed in U.S. patents Nos. 1 ,214,677 and 1 ,702,178 have employed a pair of coupled doors that swing about axes perpendicular to the ground.
  • these prior compartments use complicated structures to open and close the doors and thus can be cumbersome to open.
  • these storage members can include doors that must be opened individually rather than together. Therefore, there is a need for a worksurface system that can accommodate computer equipment as well as including a separate storage element for work papers and materials.
  • a worksurface system that is adjustable to suit the ergonomic needs of a wide range of users.
  • a storage member that includes an opening structure that is not complicated and will improve the ease with which the doors are opened.
  • a height-adjustable worksurface assembly having a leg.
  • the leg has a top portion and bottom portion.
  • the top portion includes a connection member for connection to a worksurface.
  • a first arm is attached to the top portion of the leg and extends downward to an elbow.
  • a second arm is attached to an elbow and extends downward to the bottom portion of the leg.
  • the leg has feet that rest on a base surface.
  • the top worksurface connection member, the elbow and the feet are generally aligned in a single vertical plane when the worksurface is positioned at different heights.
  • a storage member includes a top and a bottom.
  • a first side wall is attached to the top and bottom.
  • a second side wall is attached to the top and bottom.
  • the top, bottom, first side wall and second side wall define a volume of space and an opening thereto.
  • a first door has a first arm that is pivotally attached to said first side wall.
  • a second door has a second arm that is pivotally attached to the first side wall.
  • the first arm includes a first tooth section and the second arm includes a second tooth section.
  • the first and second tooth sections engage one another so that the motion of the first door is coupled to the motion of the second door.
  • the first and second doors pivot from a first position when the first door is above the top and the second door is below the bottom, and a closed position wherein the first and the second doors block the opening.
  • an antiracking mechanism for a storage member includes a top and a bottom.
  • a first side wall is attached to the top and bottom.
  • a door having opposing first and second arms is also provided.
  • the first arm and the second arm each have an arcuate arrangement of teeth.
  • the teeth mate with a first gear and a second gear, respectively.
  • the teeth are interconnected by a fixed rotatable gear shaft whereby movement of the first arm or the second arm translates via the rotation of the gear shaft into a corresponding movement of the other arm which thereby avoids the racking of the door.
  • the present invention provides a worksurface that is easily adjustable to a new height while being collapsible for transportation.
  • the present invention also provides a storage member that includes a door that is easily opened without the need for a complicated structure.
  • the storage member of the present invention includes an antiracking element that prevents damage to the unit.

Abstract

L'invention concerne une surface de travail réglable en hauteur et pourvue d'une patte. Cette patte comprend une partie supérieure et une partie inférieure. La partie supérieure comporte un élément destiné à être connecté sur une surface de travail. Un premier bras est fixé sur la partie supérieure de la patte et s'étend de haut en bas vers un coude. Un second bras est fixé sur le coude et s'étend de haut en bas vers la partie inférieure de la patte. La patte est pourvue d'un pied qui repose sur une base. L'élément de connexion de la partie supérieure de la surface de travail, le coude et le pied sont généralement alignés sur un seul plan vertical lorsque la surface de travail est positionnée à différentes hauteurs.
