Abstract
A table assembly is mounted on a wheelchair using a hinge mounted along the side of the chair arm. The table assembly has a panel with two use positions, one extending across the front of the chair and the other extending laterally to the side of the chair. The table panel may be stowed in a position alongside the chair, inside the brake and the drive wheel, beneath the arm. It is readily removed and replaced.
Claims16
In combination, a wheelchair having a chair, at least one substantially horizontal arm and drive wheels on opposite sides of the chair, and a table assembly, the table assembly comprising:
- first hinge means mounted on the arm and extending along an outer side of the arm;
- a table panel having opposite first and second faces and a mounting edge;
- second hinge means secured to the table panel adjacent the mounting edge of the table panel and having a pivot axis spaced outwardly from the mounting edge, the pivot axis being offset from the table panel so as to be spaced from the second face of the table panel, the second hinge means pivotably and slidably engaging the first hinge means for pivotal movement of the table panel about the pivot axis and for translation of the table along the pivot axis whereby the table panel may move between a first use position extending across the arm with the first face of the table panel uppermost and a storage position substantially below the arm, laterally between the chair and the adjacent drive wheel.
In combination, a wheelchair having a chair, at least one substantially horizontal arm and drive wheels on opposite sides of the chair, and a table assembly, the table assembly comprising:
- first hinge means mounted on the arm and having first hinge pivot means comprising a channel extending along an outer side of the arm, the channel having a vertically elongate profile with spaced apart upper and lower bearing surfaces;
- a table panel having opposite first and second faces and a mounting edge;
- second hinge means including table panel mounting means secured to the table panel adjacent the mounting edge of the table panel, second hinge pivot means with a pivot axis spaced outwardly from the mounting edge and spaced from the second face of the table, the second pivot means comprising an elongate shaft rotatable in the channel, slideable along the channel and vertically moveable in the channel for selective engagement with the upper and lower bearing surfaces for movement of the table panel between a first use position in which the table panel extends across the arm with the first face of the table panel uppermost and the shaft engages the upper bearing means and a storage position in which the table panel is positioned substantially below the arm, laterally between the chair and the adjacent drive wheel and the shaft engages the lower bearing surface to support the table panel in the storage position;
- first abutment means on the first and second hinge mean, engageable in the first use position to support the table panel in the first use position;
- and
- second abutment means on the first and second hinge means, engageable in a second use position of the table panel, in which the table panel projects substantially horizontally outwardly from the arm and the second hinge pivot means engages the upper bearing means for supporting the table panel in the second use position.
