STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT
(Not applicable.)
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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A travel case of the present invention is referred to generally in the drawings by reference numeral
10
. Referring to
FIG. 1
, the travel case
10
has a housing
12
enclosing a storage volume for holding clothes, accessories and the like. The housing
12
preferably includes expandible front compartments including a computer compartment
14
and an accessory compartment
16
. The housing
12
can include a fixed handle
18
and a retractable handle assembly
20
for pulling the travel case
10
as it rides on wheels
21
and
22
of a wheel assembly
23
suitably mounted at a bottom rear corner of the housing
12
. Also at the back side
15
is a tray table compartment
24
having a side flap
25
that can be opened (see arrow
27
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
50
is secured in place at openings
43
(see
FIG. 6
) by suitable fasteners and bracketry (not shown) within the housing
12
.
As shown by arrow
54
in
FIG. 3
, the tray table
26
and extension member
44
can be pulled upward to an extended position in which the hinged connections
46
and
48
are above a top
56
of the housing
12
. As shown by arrow
58
in FIG.
4
and arrow
60
in
FIG. 5
, the tray table
26
can then be rotated upwardly at the hinged connections
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
can be collapsed and neatly stowed away within the closed tray table compartment
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.
