ABSTRACT:
An improved tray attachment for a chair wherein a mounting mechanism for the tray is attached to the underside thereof, and is provided with a pin extending in parallel with one side of the tray, such pins having a free end for being slidably received in a mounting block, whereby the tray may be moved in forward and rearward directions by such slidable movement and may be pivoted to a vertical storage position about the axis of such pin. The mounting block is also pivotally mounted on a transverse horizontal extension of a vertical rod, wherein the tray may be raised and lowered by raising and lowering the vertical rod, and by fixing such rod to an arm of the chair at its desired height. The pivotal connection between the transverse rod and the mounting block permits the tray to be tilted, and a second vertical rod, attached to the opposite arm of the chair, may be raised and lowered to support the tray in a horizontal or tilted disposition. The point of contact between the tray and the second vertical rod is substantially displaced from the axis of tilting rotation of the tray, which axis is defined by the transverse rod position, and this displaced contact enhances the stability of support for the tray.
