BACKGROUND OF THE INVENTION




The present invention relates to luggage and, more particularly, to a travel case having a deployable table top for supporting objects such as a portable computer.




Luggage having compartments to store common travel items such as clothes, toiletries and other accessories are well known in the art. Similarly, cases for carrying portable computers are also well known in the art, see for example U.S. Pat. No. 5,242,056 issued to Zia et al.




Typically, airplane travelers carry portable computers in a separate case in addition to a conventional suitcase in which common travel items are stored. This is done so that the often larger suitcase can be checked with the airline and the computer can be brought onboard the airplane and used during the flight to catch up on work while away from the office. Additionally, airplane travelers also utilize their portable computers while waiting at airport terminals. Often, however, there is no suitably flat surface upon which to place a computer.




Efforts to combine conventional suitcases with computer storage and supporting cases have resulted in cases that are bulky and difficult to use. For example, U.S. Pat. No. 5,437,367 issued to Martin discloses a carrying case for electronic components including numerous foldable support platforms. This case has a large, hard housing such that it cannot be brought onboard an airplane. Instead, it must be stowed in the airplane's cargo hold such that a traveler carrying this case must forgo using the portable computer during the flight or carry an additional, smaller case, which can be awkward. Moreover, the case must be opened and the contents removed to access the collapsed supporting structures stored inside. This makes the supporting structures impractical to use at an airport terminal or at other such location. Further, the supporting structures occupy storage space which reduces the amount of travel items that can be carried within the case.




Accordingly, there is a need in the art for a compact case capable of holding travel items as well as providing a support table for a portable computer.




SUMMARY OF THE INVENTION




The travel case of the present invention provides a carrying case with a deployable tray table compactly disposed within and neatly concealed by a compartment at the back of the case. The tray table can be pivoted to rest on top of the case, thereby providing a horizontal surface to support a portable computer.




In particular, the present invention provides a travel case for storing clothing, accessories and the like including a housing defining a storage space and having a top and a back side. At the back side of the housing is a reclosable tray table compartment in which is disposed an extension member which is mounted to the housing so that it can slide in a plane parallel with the back side of the housing. The extension member has a free top end to which is a tray table is rotatably attached. When the extension member is in an extended position, the tray table can be rotated to a support position providing a generally horizontal surface suitable for supporting electronic devices, such as a portable laptop computer. When the extension member is in a retracted position, the tray table can rotate to a stored position within the compartment.




It is therefore a principle object of this invention to provide a travel case which includes a deployable tray table mounted to the housing. The tray table can be deployed to form a substantially horizontal planar surface for supporting a portable computer. The tray table can retracted to be compactly stored in a zippered compartment at the back side of the housing.




It is an additional object of this invention to combine the features of conventional luggage with the features of a portable computer support table. This is accomplished by the housing defining storage space for containing clothing, accessories and the like.




In one aspect of the invention, the extension member is locked in place when the tray table is in the support position. A latch slidably attached to the extension member and operated by the tray table when in the support position to engage the bracket. In another aspect, tray table is above the housing top when deployed to the support position. In this way, feet at the bottom of the tray table can rest upon the housing top.




It is still yet another object of this invention to provide a stable and secure support for a portable computer. This accomplished by locking the extending member in the extended position and resting the tray top on the top of the housing when in the support position. Moreover, non-skid surfaces on the top of the tray table prevent a portable computer from sliding.




In other preferred forms of the present invention, the travel case has a computer compartment for storing a portable computer at a front side. Also, the travel case includes a wheel assembly and a retractable handle for pulling the travel case.











In accordance with these and other objects which will become apparent hereinafter, the present invention will now be described with particular reference to the accompanying drawings.

in

FIG. 2

) and closed by a zipper


17


.




Referring to

FIG. 2

, the tray table compartment


24


houses a deployable tray table


26


. The tray table


26


is generally a rectangular, planar member of a suitable rigid plastic having stabilizing feet


28


and


29


at a bottom side


30


. The tray table


26


can be completely contained within the tray table compartment


24


. In this way, it does not occupy storage space within the housing reserved for other travel items. The tray table


26


is sufficient large and robust to support conventional laptop portable computers as well as other suitable items, such as food, drinks, books, files and papers. Referring momentarily to

FIG. 4

, the tray table


26


also preferably has non-skid surfaces


32


made of a suitable material such as polyvinylchloride at a top side


34


. The non-skid surfaces


32


help prevent objects from sliding off the tray table


26


. The tray table


26


also preferably includes a recess


38


at a bottom edge


40


providing a hand grip location.




Referring to

FIGS. 3 and 4

, the tray table


26


is rotatably mounted at a top edge


42


to an extension member


44


by two hinge connections


46


and


48


. The extension member


44


slides longitudinally up and down in a plane parallel to the back side


15


of the housing


12


within a recess


49


(see

FIG. 7

) of a mounting bracket


50


suitably fixed to an inner wall within the tray table compartment


24


. The mounting bracket

46


and


48


to a support position in which the top side


34


is essentially horizontal and the feet


28


and


29


rest on the housing top


56


. The tray table compartment


24


can be closed up around the extension member


44


by the zipper


17


, as shown by arrow


62


in FIG.


5


. By reversing the process shown by the arrows of

FIGS. 2-5

, the tray table


26

24


.





FIGS. 6 and 7

illustrate a latching mechanism


64


slidably attached at a back side of the extension member


44


when the extension member


44


is in the retracted and extended positions, respectively. The latching mechanism


64


is operated by the tray table


26


to lock the extension member


44


in a fixed position when the tray table


26


is in the support position. The latch mechanism


64


includes latch pins


66


and


67


slidably fastened to the extension member


44


by clips


70


. The latch pin


66


includes an elongated body


72


having a free end


74


slidable within openings


76


of the extension member


44


. An opposite confined end


78


has a reverse Z-shaped member


96


with a post


80


to which is fit a compression spring


82


. The confined end


78


is retained by a wall


84


which also confines wedge


86


as well as catch


88


. Catch


88


has a rounded end


90


and a wedged end


92


which cooperates with the wedge


86


and the reverse Z-shaped member


96


to translate laterally as the latch pin


66


is moved. Latch pin


67


is identical to latch pin


66


and has elements corresponding to those stated above with respect to latch pin


66


, referred to in

FIGS. 6 and 7

by corresponding odd numerals. The latch pin


67


is oriented, however, as a longitudinal mirror image of latch pin


66


so that the confined end


79


has a Z-shaped member


97


.




Thus, as shown in

FIG. 6

when the tray table


26


is in the stowed position, and the extension member


44


is retracted, the free ends


74


and


75


of the latch pins


66


and


67


extend past the openings


76


and


77


in the extension member


44


. However, when the tray table


26


is fully deployed to the support position, the extension member


44


is in the extended position and the bottom side of the tray table


26


contacts the free ends


74


and


75


of the latch pins


66


and


67


. This forces the latch pins


66


and


67


downward and compresses the springs


82


and


83


. Referring to

FIG. 8

, the movement of the latch pins


66


and


67


causes the Z-shape to cooperate with the wedges


86


and


87


and wedge ends


92


and


93


of the catches


88


and


89


so as to push the round end


90


and


91


of the catches


88


and


89


into slots


100


and


101


in the bracket


50


. This locks the extension member


44


in the fully extended position. By lifting and rotating the tray table


26


back again, the tray table


26


no longer contacts the free ends


74


and


75


of the latch pins


66


and


67


and the compressed springs


82


and


83


return the latch pins


66


and


67


to their initial position. Retainers


102


and


103


cover the Z-shape ends


78


and


79


when the extension member


44


is extended. As shown in

FIG. 7

, the extension member


44


has longitudinal grooves


104


and


105


(shown in phantom) allowing it to ride along rails


106


and


107


at the inside of the bracket


50


as it is extended and retracted.




The present invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
