US 4,679,509 A · Wheel chair table system

Abstract

A table designed for ease of use by the occupant of a wheel chair having a shaped, cut-back, front edge to allow the torso of the user to extend partially into the working surface, enabling the user to have ease of access to the entire working surface. A peripheral lip or ridge about the back and side edges of the table prevents articles from falling off and out of reach of the user, and the height and table top size are dimensional for use by a wheelchair occupant. The table has casters mounted on its rear leg portions but not on its front leg portions. The table is easily moved by the user who simply tilts the table to lift its front leg portions off of the ground, tilting the table onto the casters mounted on its rear legs, and then rolls the table with him. When the table is tilted for movement the peripheral ridge acts to keep articles on the table. When the table is at a desired location, its front legs are lowered back down into hold contact with the floor. The table is of simple construction, preassembled and then disassembled, with all the parts provided in kit form for assembly and finishing by a handicapped person.

A wheel chair table system, comprising:

a horizontal planar surface disposed generally above a pair of horizontally parallel arms of a wheelchair, said planar surface having a generally straight rear edge, a pair of generally parallel side edges extending laterally forward from the ends of said rear edge and separated by a distance generally wider than said arms of said wheelchair, and a front edge extending laterally between the forward ends of said side edges and generally parallel to said rear edge;
a notch in said front edge extending rearward into said planar surface, said notch having a straight rear edge portion disposed generally parallel to said rear edge and a pair of straight side edges extending angularly outward from said rear edge to define a cut out having a narrower rear portion and a wider front portion;
a pair of generally opposed planar side members extending laterally downward from a lower surface of said planar surface;
means for retaining said planar side members and said planar surface in a rigidified configuration;
a pair of opposed rollers formed by attaching a roller to a rear, lower portion of each of said side members to provide for movement of said planar surface, said opposed rollers further being disposed in a vertical plane generally parallel to said rear edge of said planar member to provide a means for rotating said planar surface to a tilted configuration with its front edge raised to a position higher than its rear edge;
a footing extending downward from a front, lower portion of each of said side members having a lower surface suitable for engaging a floor surface to prevent lateral motion thereon, said footings forming a pair of opposed footings for restraining lateral motion of said planar surface;
a handle attached to a portion of said front edge on both sides of said cut out for use by an invalid in a wheel chair to rotate and lift said planar surface about said opposed rollers upward from a first configuration in which said footing engages said floor surface and a configuration in which said cut out in part, surrounds a forward body portion of said invalid, to a second configuration in which said cut out rotates with said planar surface and moves upward along a frontal periphery of said invalid to allow said planar surface to rotate to its tilted configuration with its front edge in a higher position than its rear edge while remaining in a configuration in which said cut out in part, still surrounds a forward body portion of said invalid, to further allow a separation between said footing and said flooring so that said planar surface may be moved about by said invalid from a first location to a second location with said wheel chair;
and
a lip extending around at least three edges of said planar surface, said lip having a portion extending upward from said rear edge and including generally parallel portions extending upward from said side edges to provide a means when said planar surface is in its tilted configuration for retaing articles on said planar surface.
