Abstract
A vertically adjustable table appropriate for use with a chair or wheelchair whereby the table surface remains in a fixed horizontal plane and is adjustable only along the vertical plane. The table surface may be manually adjusted along guideposts with the use of a cable and pulley system, such that the user may easily adjust the table by pulling the table surface down for use and lift the table surface up when it is no longer in use. The guideposts are of sufficient length to allow the user to easily maneuver underneath the table surface when the table surface is in a raised position. This system is of particular use for individuals with physical limitations.
Claims5
A table and chair combination that enables a user to enter and exit said chair without removing said table away from the front of said chair, said table and chair combination comprising:
- a table surface having opposing sides, said table surface being moveable in a vertical direction;
- a chair having arms and a height wherein said chair is positioned behind said table;
- two vertical guideposts, each having a top end, a bottom end and a length greater than the height of said chair, wherein said opposing sides of said table surface are slidably connected to said guideposts between the top end and the bottom end and wherein said guideposts are fixed in a stationary position in front of and on either side of said chair;
- a pulley system having a mechanical advantage and having at least one flexible cable having one end attached to said table surface and another end attached to a counterweight, wherein the weight of said counterweight corresponds to the weight of said table surface and the mechanical advantage of said pulley system, such that said table surface may be lowered by said user to place said table surface upon said arms of said chair placed between said guide posts so that said table surface is positioned in front of a user seated in said chair and such that said user can raise said table surface while seated in said chair so that said user can pass under said table surface when exiting said chair.
