Abstract
Abstract An improved serving tray according to the teachings of the present invention is disclosed as including a window abutting element which is laterally positionable allowing a window abutting edge to abut with and fulcrum on the outside surface of the window to compensate for variations of the angle of the window to allow the serving platform of the serving tray to be horizontal. The window abutting element is laterally positionable by slideably mounting it to the bottom surface of the serving platform. In its most preferred form, the window abutting element is slideably mounted by arms extending generally parallel to and spaced from the rear legs of the serving tray. The window abutting element is held in one of multiple positions by teeth formed on the bottom surface of the serving platform and formed on the window abutting element. The window abutting element is biased towards the serving platform and is allowed to be moved away from the serving platform to separate the teeth of the window abutting element from the teeth of the serving platform. In its most preferred form, the window abutting element includes a tongue formed integrally therewith and slideable along a connector extending between the arms and the rear legs to bias the window abutting element towards the serving platform and to allow separation of the teeth.
