IV. DETAILED DESCRIPTION OF THE INVENTION

The present invention generally relates to tray table devices and related methods. According to some embodiments, a tray table can be foldable and/or expandable. Some embodiments include features that enable stowing the tray table and/or components thereof.
According to one embodiment, a tray table device includes a tray frame member. The tray frame member can have a generally rectangular shape, or any other suitable shape. In some embodiments the tray frame member comprises a top portion, a bottom portion and four side portions. The top and bottom portions are spaced apart to define a thickness, and the thickness is bounded by the side portions. In some embodiments the tray frame member defines an outer perimeter and at least one inner perimeter. An inner perimeter defines a space for accepting a tray top member, which is adapted to fit within the inner perimeter. In some embodiments a tray top member can comprise a generally rectangular shape, and can include a means for attaching the tray top member to the tray frame member. Some embodiments also include a tray bottom member. A tray bottom member can comprise a generally rectangular shape adapted to fit within an inner perimeter of the tray frame member. In some embodiments the tray bottom member is attached to the tray frame member through one or more collapsible side walls.
According to some embodiments, the tray frame member can include a means for mounting the frame member to a vehicle. Such means for mounting can be disposed at or near one or more side portions and/or the bottom portion of the tray frame member. And, in some embodiments the means for mounting can enable a swinging relation between the tray frame member and the vehicle, including a range of motion from at least about 0 to 90 degrees relative to a floor of the vehicle. In some embodiments, the means for mounting can include one or more devices selected from the group consisting of a hinge, a ball and socket pivotable joint, a pin and socket rotatable joint, and a foldable brace.
Some embodiments include one or more means for fixing the orientation of the tray frame member. For example, one suitable fixing means is capable of reversibly fixing the tray frame member in a horizontal orientation relative to a floor of the vehicle. A variety of mechanical means can be used to perform this function including, without limitation, one or more of a latch, a hook, a mechanical stop or a foldable brace.
A tray top can define a shape such as a generally rectangular shape. Rectangular tray tops include a top face, a bottom face, and four side faces. In some embodiments, tray tops are adapted to fit within a perimeter of the tray frame member. Some embodiments can also include a means for attaching the tray top to the tray frame member in a swinging relation. According to some embodiments, a suitable means for attaching the tray top to the tray frame member can include, without limitation, one or more of a hinge, a ball and socket pivotable joint, a pin and socket rotatable joint, or any combination thereof. For example, the one or more hinge members can be affixed to the tray top and to the tray frame member so that the tray top is free to swing out and away from the tray frame member.
A tray bottom member can define a shape such as a generally rectangular shape. Rectangular tray bottoms include a top face, a bottom face, and four side faces. In some embodiments, a tray bottom member is adapted to fit within a perimeter of the tray frame member. Tray bottom members can be affixed to the tray frame member by any of a variety of collapsible means including, without limitation, netting, fabric, accordion-folded materials, string, rope, chain, cable, chain mail, woven metal fiber, and the like. Some embodiments include at least one collapsible side member.
Some embodiments also include a means for raising and lowering the tray bottom member and/or collapsing the collapsible member. In some embodiments the means for raising and lowering can comprise one or more of a string, rope, chain, cable and the like, or any combination thereof. Furthermore, in some embodiments, the means for raising and lowering can operate manually or automatically. For instance, in one embodiment the means can include a pull-cord in mechanical communication with the at least one collapsible side member. According to such embodiments, the tray bottom member can be raised by pulling the pull-cord, and the tray bottom member can be lowered by releasing the pull-cord. In automatic embodiments, a collapsible side member can be raised and lowered with the aid of a motorized means. For instance, a motor can be used to draw and release a cord or chain in mechanical communication with a collapsible side member.
Some embodiments having a pull-cord also include a pull-cord locking means, for locking the position of the pull-cord. For example, when the pull-cord is drawn and the tray bottom member is in a raised orientation, it may be desirable to lock the tray bottom member in the raised orientation by locking the pull-cord in the drawn state. This can be accomplished with any of a variety of structures including, without limitation, a cinch, a slideable clip, a clasp, a knot, and the like, or any combination thereof.
Referring now to the drawings wherein the showings are for purposes of illustrating embodiments of the invention only and not for purposes of limiting the same, FIG. 1 is a series of drawings showing various configurations of one embodiment. FIG. 1A shows the embodiment in an open configuration 100. According to FIG. 1A the embodiment comprises a tray frame member 110 defining an inner perimeter 112. A tray top member 120 is adapted to fit within the inner perimeter 112, and is attached to the tray frame member 110 through a pair of hinges 122. The embodiment also includes a tray bottom member 140, which is attached to the tray frame member 1 10 through a collapsible side member 130. In this embodiment, the collapsible side member 130 comprises a net structure. The collapsible side member can be collapsed by pulling the pull-cord 132, and the collapsed orientation can be maintained by applying a pull-cord locking means. According to FIG. 1A the pull-cord locking means comprises a slideable clip 134.
FIG. 1B shows the embodiment of FIG. 1A where the tray top member 120 is in a closed configuration 102, and is fitted within an inner perimeter 112 of the tray frame member 110. FIG. 1C shows a configuration 104 where the tray top member 120 is in an open orientation and the tray bottom member 140 is in a raised orientation. FIG. 1C shows that the pull-cord 132 has been pulled, thereby collapsing the collapsible side member 130 and raising the tray bottom member 140 into an inner perimeter of the tray frame member 110. The tray frame member 110 can have different inner perimeters for accepting the tray top member 120 and the tray bottom member 140. FIG. 1D shows still another configuration 106, wherein the tray top member 120 is in a closed configuration and the tray bottom member 140 is in a raised configuration. Finally, FIG. 1E shows a configuration 108, wherein the tray top member 120 is in a closed orientation, the tray bottom member 140 is in a raised orientation, and the tray frame member 110 is folded against the seat 150 or seat bracket to which it is mounted. Thus, in FIG. 1E the embodiment is in a stowed configuration.
FIG. 2 shows two additional embodiments that include one or more accessories. In FIG. 2A, an embodiment 200 is shown that includes a cooler 210. The cooler 210 fits within the tray frame member 110 when the tray frame member 110 is in a deployed, rather than stowed, orientation. Furthermore, the cooler 210 can include one or more electrical contacts for providing power to a refrigeration means disposed in the cooler 210. Alternatively, the cooler 210 can rely primarily on insulation rather than refrigeration, and therefore may include no electrical contacts. FIG. 2B shows an embodiment 202 that includes a file accessory 220. The file accessory 220 fits within the tray frame member 110 when the tray frame member 220 is in a deployed orientation.
The embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above methods and apparatuses may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
