Description




1. FIELD OF THE INVENTION




The invention generally relates to an adjustable tray. More particularly, the invention relates to a tray for a furniture unit of the type used for a work station.




2. BACKGROUND OF THE INVENTION




The wide spread use of computers has created a need for work stations which can accommodate computer equipment and provide a convenient environment in which an individual may utilize the computer equipment. One problem encountered in providing a convenient environment for utilization of the computer equipment is the problem of positioning a book or document in a position so that the person working at the computer work station can conveniently transcribe or edit materials on the computer without having to turn to one side to look at a document, i.e., an in-line document holder. The general limitation to providing an in-line document holder at a computer work station is a lack of depth of the traditional work surface. A conventional document holder does not fit into the limited space between a key board and a monitor.




Thus, it would be desirable to have an in-line document holder which can hold a document or book in a position convenient for viewing the document and the computer monitor without requiring the operator's head to turn.




3. SUMMARY OF THE INVENTION




The present invention is an adjustable tray. In one exemplary embodiment the tray may be used in a furniture unit of the type suitable for use as a work station. The tray has a base with two supports attached to parallel sides of the side of the base. The supports extend upward in a direction substantially normal to the base. A support member is slidable and rotatable connected to the two supports. The support member is moveable between a position substantially upright with respect to the base and a position substantially co-planar with the base. In the substantially upright position, the support member may support copy such as documents or a book, for example. In the co-planar position, the support member may serve as a writing surface or as a shelf for supporting small articles and the like.




The tray may optionally include features facilitating its use as a portion of a work station including, but not limited to, at least one storage compartment, a wrist support pad and the like.

400


permits the support member


500


to be moved from a substantially upright position to a substantially horizontal position when the support bar


400


is moved along the slots


222


,


272


and rotated about the axis defined by the pivot pin


470


.




As shown in FIG.


3


and in greater detail in

FIG. 14

, the support member


500

206


,


256


when the support member is in the upright or substantially vertical position. Substantially vertical is taken to mean that the support member


500


is tilted at an angle such that one edge of support member surface


540


is elevated with respect to the opposite edge of support member surface


540


. The positioning of the adjustment notches


560


,


570


against the side wall tops


560


,


570


permits the substantially upright support member


500


to be tilted at an angle other than 90 with respect to the base. A tilt of the support member


500


facilitates positioning copy against the support member. Further, the positioning of the position adjustment notches


560


,


570


against the side wall tops


206


,


256


serves to hold the support member


500


in a substantially upright position and restrict undesirable movement of the support member


500


during the use of the support member


500


in its upright position.
