Description
FIELD OF THE INVENTION
[0001] The present invention relates in general to mobile platform
service item storage and handling and more specifically to an
aircraft galley cart storage and retrieval system and method of
use.
BACKGROUND OF THE INVENTION
[0002] Mobile passenger carrying platforms, such as aircraft,
ships, trains, buses, etc. often provide food or beverages for
passengers. Food and beverages are commonly heated or otherwise
prepared for distribution by personnel within galley areas. Food
and beverages prepared in the galley are frequently transported to
individual passenger seating areas using galley carts. Galley carts
in many industries including the aircraft industry have been
standardized in size. For example, an exemplary aircraft galley
cart is approximately 34 inches high, approximately 12 inches wide
and approximately 40.5 inches deep and can weigh approximately 250
pounds. Galley carts are therefore provided with wheels to provide
mobility for the carts. For extended flights requiring two or more
meals, several dozen carts may be required.
[0003] Service products including food, beverages and condiments
are frequently loaded into multiple carts before the mobile
platform departs. Separate meals of multiple meal flights are often
accommodated in assigned groups of carts. Based on their quantity,
size and weight, a system for storage and retrieval of carts is
often necessary. In the aircraft industry, for example, galley
carts are frequently stored at passenger deck level, under
countertops within one or more galley areas. It is undesirable to
significantly expand galley "footprint" size to accommodate more
floor-area carts because this conflicts with the need to maximize
the number of passenger seats. For the same reasons, it is
undesirable to increase the number of galleys. Additional galley
cart storage has been alternatively provided in lower levels of the
aircraft, but this reduces available stowage space for cargo in the
lower level.
[0004] Because galley cart weight can often reach 250 pounds, it is
impractical for personnel to manually manipulate or lift carts to
any significant height. This has prevented vertical stacking of
carts in confined spaces such as a galley.
SUMMARY OF THE INVENTION
[0005] According to a preferred embodiment of the present
invention, a mobile platform service product storage and retrieval
system includes a plurality of joined walls defining a galley area.
A plurality of mobile carts is operably storable in the galley
area. A first side-by-side subgroup of the mobile carts is
provided. A second side-by-side subgroup of the mobile carts is
positioned within the galley area above the first subgroup.
[0006] According to another preferred embodiment of the present
invention, a mobile platform service product storage and retrieval
system includes a plurality of joined walls defining a galley area.
A plurality of mobile carts are operably storable in the galley
area, including a first cart subgroup and a second cart subgroup
positioned above the first subgroup. A substantially circular rack
defines a plurality of predetermined mobile cart parking locations.
Each of the locations is operable to store one of the mobile carts
of the second cart subgroup.
[0007] According to yet another preferred embodiment of the present
invention, a service product storage and retrieval system for a
mobile platform includes a plurality of joined walls defining a
galley area. A plurality of mobile carts are operably storable in
the galley area in one of a first cart subgroup and a second cart
subgroup. Each of the subgroups have the mobile carts arranged in a
side-by-side configuration. A rack is operable to support each of
the mobile carts of both the first and second subgroups. The rack
is elevated above a galley area passageway.
[0008] According to still yet another preferred embodiment of the
present invention, a galley cart storage and retrieval system for a
mobile platform includes a first row of galley carts. A second row
of galley carts is positioned above the first row. A third row of
galley carts is positioned both approximately level with and in
front of the first row. Each of the galley carts of the first,
second and third rows are arranged in a side-by-side configuration
of adjacent carts within each of the rows. An automated rotation
mechanism is operable to simultaneously rotate both the first row
and the second row of galley carts. Rotation of the first row and
the second row of galley carts operably positions a desired one of
the first row and the second row of galley carts for removal
through an end cart removal cavity of the third row.
[0009] According to a further preferred embodiment of the present
invention, a method for storing and retrieving carts of a mobile
platform galley comprises: grouping a plurality of mobile carts
into a side-by-side orientation to each other; dividing the mobile
carts into at least a first cart group and a second cart group;
positioning the second cart group above the first cart group within
the mobile platform galley; automatically accessing an individual
mobile cart of the second cart group; and automatically
transferring the individual mobile cart to an access area in the
first cart group.
[0010] The features, functions, and advantages can be achieved
independently in various embodiments of the present inventions or
may be combined in yet other embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] The following description of the preferred embodiments is
merely exemplary in nature and is in no way intended to limit the
invention, its application, or uses.
[0034] Galley cart storage systems as provided herein are described
in reference to exemplary aircraft applications. Galley cart
storage systems of the present invention are not intended to be
limited to aircraft applications, but can be used in any mobile
platform also including, but not limited to ships, trains, buses,
etc.
[0035] According to a preferred embodiment of the present
invention, and referring to FIG. 1, an aircraft 10 includes wings
11 and a galley cart storage system 12 of the present invention,
positioned within a passenger seating area of aircraft 10. Galley
cart storage system 12 is shown positioned forward of wings 11, but
is also preferably positioned aft of wings 11 when used in economy
class seating areas of aircraft 10, normally positioned aft of
wings 11. Galley cart storage system 12 is provided in a galley
area 14. Galley area 14 includes a standard galley portion 15,
including: at least one galley wall 16; a countertop area 18; a set
of cabinets 20; and a galley passageway 22. Forward of standard
galley portion 15 is a lower cart group 24, an upper forward cart
group 26, and an upper aft cart group 28. Both upper forward cart
group 26 and upper aft cart group 28 are positioned above a
passenger cabin ceiling. Upper aft cart group 28 is also positioned
above the galley passageway 22. Galley area 14 is positioned and
supported on a passenger deck 30. FIG. 1 also shows a longitudinal
axis 32 for aircraft 10. Galley passageway 22 is oriented
approximately perpendicular to longitudinal axis 32.
[0036] Referring to FIG. 2, galley area 14 further includes a
galley ceiling 34 in addition to the one or more galley walls 16.
Galley walls 16 and galley ceiling 34, in addition to passenger
deck 30 (shown in FIG. 1), provide sealed wall sections to enclose
portions of galley area 14 to be subsequently refrigerated.
Refrigeration equipment and tubing (not shown) is known in the art
and is provided to refrigerate food and/or beverages in galley area
14 to temperatures of approximately 35.degree. F. A rack 36
supports a plurality of galley carts 38 of both upper forward cart
group 26 (shown) and upper aft cart group 28 (shown in FIG. 1).
Both upper forward cart group 26 and upper aft cart group 28,
together with rack 36, are positioned approximately perpendicular
to longitudinal axis 32. An additional plurality of galley carts 38
are locally stowed and available for manual access under countertop
area 18. Galley walls 16 are not required to enclose each galley
cart for cooling, and alternatives for cooling include using dry
ice local to any cart or using refrigerated air piping ducted to
individual or groups of galley carts 38. Increased strength floor
beams 37 are used in passenger deck 30 as necessary, in this and
all embodiments of the present invention, to support the additional
weight from increased quantities of galley carts 38.
[0037] Galley carts 38 are stored and retrieved in both upper
forward cart group 26 and upper aft cart group 28, respectively, by
positioning each individual galley cart 38 into a cart access area
40 and vertically lifting each galley cart 38 via a cart lift 42 in
a cart vertical lift direction "A". When each galley cart 38
reaches the elevation of rack 36, a mechanism (not shown)
horizontally translates each galley cart 38 in a cart storage
direction "B" (shown for the exemplary upper forward cart group 26)
to a predetermined parking position 43 on rack 36. Rack 36 is
elevated to provide a passageway headroom height "C". Galley carts
38 are moved out of cart transfer space 48 and into upper forward
cart group 26 in a cart forward loading direction "D". Similarly,
galley carts 38 are moved into upper aft cart group 28 in a cart
aft loading direction "E". In this embodiment, any galley cart 38
positioned on rack 36 is positioned in a randomly accessible
configuration.
[0038] Based on the ability to vertically lift each galley cart 38
using cart lift 42, galley area 14 is expanded vertically into
overhead area 44 of aircraft 10. This advantageously uses available
space within overhead area 44, while still retaining the elevated
galley carts 38 within a refrigerated envelope of galley area 14.
In the configuration shown in FIG. 2, galley area 14 is
approximately centrally divided about an aircraft centerline 46.
This maximizes an available envelope for galley area 14. It is also
possible, however, to shift galley area 14 to either a left or a
right position about aircraft centerline 46 as viewed in FIG. 2,
thereby providing an off-center arrangement for galley area 14. An
off-center arrangement for galley area 14 is advantageous in
aircraft 10 having non-balanced seating arrangements, for example,
an arrangement having three seats on one side of aircraft
centerline 46 and two seats on the opposite side of aircraft
centerline 46 (not shown for clarity).
[0039] Referring to both FIGS. 2 and 3, galley cart storage system
12 provides a cart transfer space 48 approximately centrally
dividing upper forward cart group 26 from upper aft cart group 28.
Cart transfer space 48 provides for an athwartship translation of
individual galley carts 38 on rack 36 to access one of
predetermined parking positions 43 on rack 36. The passageway
headroom height "C" permits personnel in galley area 14 freedom of
motion within the galley and under the stowed galley carts 38 of
upper aft cart group 28. Each galley cart 38 is locked in position
on rack 36 by locks known in the art (not shown).
[0040] As shown in FIG. 3, each galley cart 38 includes a pair of
opposed cart "sides" 39. To maximum storage volume within galley
area 14, each adjacent pair of galley carts 38 is arranged such
that adjacent cart sides 39 approximately abut one another. This
configuration is herein referred to as a "side-by-side"
configuration. A minimum clearance between adjacent galley carts 38
is provided to allow ease in loading and/or unloading carts from
rack 36. The side-by-side configuration is shown in greater detail
in reference to FIG. 2.
[0041] Referring next to FIG. 4, a galley cart storage system 50
includes a lower cart group 52 and an upper cart group 54. The
standard galley portion 15 is similarly provided as shown and
described in reference to FIG. 1. Only the differences between FIG.
1 will therefore be described in reference to FIG. 4. Individual
galley carts 38 are raised from the level of passenger deck 30 to
upper cart group 54 via a central cart lift 56, centrally disposed
within upper cart group 54. Each galley cart 38 is provided with a
predetermined parking location 58 in upper cart group 54.
[0042] As best seen in FIG. 5, central cart lift 56 vertically
raises each galley cart 38 from a cart access area 60 on a
rotatable turntable 62. When central cart lift 56 raises the
individual galley cart 38 to an elevation of a circular platform
64, rotatable turntable 62 is rotated to align galley cart 38 with
a selected one of predetermined parking locations 58. A mechanism
(not shown) translates galley cart 38 from the central cart lift 56
to its predetermined parking location 58 and locks the galley cart
38 in position. Similar to the configuration shown in FIG. 3,
circular platform 64 provides sufficient headroom for personnel
within galley passageway 22 (shown in FIG. 4). Similar to galley
cart storage system 12, galley cart storage system 50 positions
galley carts 38 within a portion of overhead area 44,
advantageously using overhead area 44 for storage of galley carts
38 within and adjacent to galley area 14. Galley walls and a galley
ceiling (not shown for clarity) can similarly enclose galley carts
38 stored on circular platform 64 to permit refrigeration of galley
carts 38 of galley cart storage system 50. Alternative forms of
refrigeration, as noted herein, can also be provided. As an
alternative to galley cart storage system 50, (not shown), the
rotatable turntable 62 can be replaced by a fixed platform, and
circular platform 64 can be made rotatable to receive galley carts
38.
[0043] Referring to FIG. 6, a galley cart storage system 66
includes a lower cart group 68 and an upper cart group 70. Galley
carts 38 are vertically lifted within end lift bay 72 from lower
cart group 68 to upper cart group 70. Galley cart storage system 66
provides a plurality of galley carts 38 in upper cart group 70 each
stacked approximately in vertical alignment with a corresponding
galley cart 38 of lower cart group 68. Similar to previous
embodiments, the standard galley portion 15 is positionable on an
opposed side of a galley passageway as shown and described in
reference to FIG. 1.
[0044] FIG. 7 identifies a flow path for lifting individual galley
carts 38 of galley cart storage system 66. Initially, an individual
galley cart 38 is positioned within a cart access area 74 and
vertically lifted in the cart vertical lift direction "A" by a cart
lift 76. When cart lift 76 reaches the approximate elevation of a
rack 78, the galley cart 38 is transversely, horizontally
translated in the cart storage direction "B". Galley cart storage
system 66 also retains a countertop space 77 between lower cart
group 68 and an upper cart group 70. Because upper cart group 70
provides only a single row of galley carts 38, and does not have an
external access area for pre-selecting locations on rack 78 for
each galley cart 38, galley carts 38 positioned on rack 78 are
stowed in a first-in/last-out configuration. For example, an end
cart 79 in upper cart group 70 is the first galley cart 38
positioned on rack 78. End cart 79 is therefore the last cart
removed from rack 78.
[0045] Galley cart storage system 66 also provides individual
galley carts 38 and an envelope of the associated galley area
within overhead area 44, thus advantageously utilizing space in
overhead area 44. Due to the alignment of galley carts 38 on rack
78 being substantially vertically above galley carts 38 in lower
cart group 68, the overhead space within the passageway of the
galley is not impacted for this embodiment. Therefore, galley cart
storage system 66, compared to galley cart storage systems 50 and
12, provides a cart storage envelope with no galley passageway
impact.
[0046] Referring next to FIGS. 8 and 9, a galley cart storage
system 80 includes a lower cart group 82, a middle cart group 84,
and an upper cart group 86. An end lift bay 88 is provided to shift
individual carts from the elevation of passenger deck 30 to either
middle cart group 84 or upper cart group 86, respectively. End lift
bay 88 provides a cart access area 90. Individual galley carts 38
which are to be lifted to either middle cart group 84 or upper cart
group 86 are first positioned within cart access area 90. A cart
lift 92 then vertically lifts each individual galley cart 38 in the
cart lift direction "A" to an elevation of either a central rack 94
or an upper rack 96. Central rack 94 supports the individual galley
carts 38 of middle cart group 84. Upper rack 96 supports the
individual galley carts 38 of upper cart group 86. When the
individual galley cart 38 reaches the appropriate elevation, it is
transferred in the cart storage direction "B" to the appropriate
one of middle cart group 84 or upper cart group 86.
[0047] Because carts of both middle cart group 84 and upper cart
group 86 are in general vertical alignment with the carts of lower
cart group 82, any cart positioned in either middle cart group 84
or upper cart group 86 are positioned in a first in/last out
configuration as described in reference to FIG. 7. For example, a
middle group end cart 98 and an upper group end cart 100 are the
first carts of the middle cart group 84 or the upper cart group 86
to be loaded, and would therefore be the last cart unloaded from
these positions. Similar to previous embodiments noted herein,
galley cart storage system 80 provides storage for individual
galley carts 38 within overhead area 44.
[0048] Referring next to FIGS. 10 and 11, a galley cart storage
system 102 includes a lower cart group 104 and an upper cart group
106. An end lift bay 108 vertically transfers individual galley
carts 38 from an elevation of passenger deck 30 to upper cart group
106. Similar to previous embodiments, galley cart storage system
102 can also include a standard galley portion 15 within the galley
configuration.
[0049] A cart access area 110 of end lift bay 108 is first loaded
with an individual galley cart 38. A cart lift 112 lifts the galley
cart 38 in the cart vertical direction "A" until the galley cart 38
reaches an elevation of a rack 114. A galley cart 38 is thereafter
translated in the cart storage direction "B" to a stored position
on rack 114. Translation in the cart storage direction "B" can be
either automatic or manual. Galley carts 38 of upper cart group 106
are directly accessible by personnel in the galley area, such that
if power to operate cart lift 112 is not available, contents of
these carts can be removed by opening the galley cart door. Similar
to previous embodiments, upper cart group 106 is substantially
vertically aligned above lower cart group 104. Galley carts 38
stored in upper cart group 106 are therefore provided in a first
in/last out configuration. For example, end cart 116 of upper cart
group 106 is the first galley cart 38 loaded onto rack 114 and
therefore is the last galley cart unloaded from rack 114.
[0050] Galley cart storage system 102 provides a two level
configuration of galley carts which fits within a standard height
galley. A galley ceiling 118 for cart storage system 102 therefore
does not impact overhead area 44. Space normally devoted to a
second standard galley portion 15 is completely converted for use
in galley cart storage system 102 for storage of galley carts 38,
doubling the number of galley carts 38 stored. No counter space or
cabinets are provided in the immediate area of galley cart storage
system 102 adjacent to the lower cart group 104 or the upper cart
group 106.
[0051] Referring next to FIGS. 12 and 13, a galley cart storage
system 122 increases a galley width "F" from known galley
dimensions by a galley cart depth "G". Galley cart storage system
122 provides a front cart section 124, and a rear cart section 126.
Rear cart section 126 is positioned adjacent a galley wall 128.
Because rear cart section 126 is provided behind front cart section
124, two cart lifts are provided at opposite ends of rear cart
section 126 to rotate individual galley carts 38 stored within rear
cart section 126. These include a first cart lift 130 and a second
cart lift 132. Access for loading or unloading individual galley
carts 38 from rear cart section 126 is at horizontally opposed ends
of front cart section 124, including a first end cart access
position 134 and a second end cart access position 136,
respectively. A countertop 137, and food service devices 139
(including coffee makers, ovens and cabinets known in the art) are
provided above front cart section 124 for access and food
preparation by personnel located in a galley passageway 120. As
best seen in FIG. 13, rear cart section 126 is divided into a lower
rear cart subgroup 138 and an upper rear cart subgroup 140. Galley
carts 38 are stored on a rack 141 of upper rear cart subgroup
140.
[0052] Referring next to FIGS. 14 and 15, a galley cart storage
system 142 provides an arrangement having a galley cart storage
system 122 and a cart storage system 144. Cart storage system 144
is a mirror image of galley cart storage system 122. Both galley
cart storage system 122 and cart storage system 144 are positioned
about a galley passageway 146 which is centrally divided by a
galley centerline 148.
[0053] Referring next to FIGS. 16 and 17, the arrangement and an
exemplary cart transfer path to either load or unload individual
galley carts 38 from either galley cart storage system 122 or cart
storage system 144 is shown. FIG. 16 identifies that rear cart
section 126 provides a plurality of galley carts 38 stored on rack
141. Galley carts of upper rear cart subgroup 140 are generally
aligned vertically with galley carts of lower rear cart subgroup
138. In an exemplary flow path, first cart lift 130 is used to
raise individual galley carts 38 from lower rear cart subgroup 138
to upper rear cart subgroup 140. Second cart lift 132 is used to
lower galley carts 38 from upper rear cart subgroup 140 to lower
rear cart subgroup 138. In one preferred embodiment, a first
transport device 150 is used to horizontally translate individual
galley carts 38 of both lower rear cart subgroup 138 and upper rear
cart subgroup 140 in a rotational manner. A first end bay 152 and a
second end bay 154 are provided for lowering or raising individual
galley carts 38, respectively.
[0054] In an exemplary path shown in FIG. 16, an individual galley
cart 38 labeled "X" is accessed for removal by translating each of
the individual galley carts 38 of upper rear cart subgroup 140 in a
first direction "H" as shown. As each successive galley cart 38
enters first end bay 152, it is lowered by second lift 132 to lower
rear cart subgroup 138. As each successive galley cart 38 of lower
rear cart subgroup 138 enters second end bay 154, it is raised by
first cart lift 130 to upper rear cart subgroup 140 and supported
by rack 141. The direction of galley cart motion in lower rear cart
sub group 138 is in a second direction "K" as shown. In the
exemplary case shown, when galley cart 38 labeled "X" reaches the
first end bay 152, designated "Y", the galley cart is positioned
for removal from rear cart section 126. In an alternative
embodiment, first transport device 150 translates individual galley
carts 38 to any one of a plurality of individual storage locations
151 of lower rear cart subgroup 138, and a second transport device
153 translates individual galley carts 38 to any one of a plurality
of individual storage locations 155 of upper rear cart subgroup
140. In this manner, any desired galley cart 38 can be accessed by
moving the desired galley cart until it reaches an end bay, such as
end bay 152, for removal. In still another preferred embodiment
(not shown for clarity), rack 141 is either modified or eliminated
and a plurality of individual cart lifts, such as first cart lift
130, are each positioned in vertical alignment between any two
vertically aligned individual storage locations 151 and individual
storage locations 155. In this embodiment, galley carts 38 are
positioned in a vacated individual storage location 151 when a
galley cart 38 is positioned in the corresponding vertically
aligned individual storage location 155.
[0055] FIG. 16 further identifies at least one structural device
157 used to contain and/or restrain galley carts 38 under crash
load conditions. Structural device 157 includes, but is not limited
to: structural walls, hold-down clamps, brackets and other devices
known in the art to restrain galley carts.
[0056] As best seen in FIG. 17, from the "Y" position shown in FIG.
16, galley cart "X" is translated in a longitudinal direction "M"
from rear cart section 126 to front cart section 124 and is
accessible via first end cart access position 134. Galley carts 38
are translated in longitudinal direction "M" via either an
automatic portion of transport device 150, or optionally, can be
manually pulled from rear cart section 126 to front cart section
124 (acting as a vacated space) using a manual translation device
159. Manual translation device 159 includes, but is not limited to,
a pullrod having a hook or clasp to grasp individual galley carts
38, or a winch having a cable/latch to grasp and remove a galley
cart 38 from under countertop 137 (shown in FIGS. 13 and 15).
Galley carts 38 are also accessible for loading or unloading at
second end cart access position 136 of front cart section 124. The
remaining cart positions in front cart section 124 are manually
accessible at any time without the use of transport device 150.
When transport device 150 is not in operation, individual galley
carts 38 can be stored in either first end cart access position 134
or second end cart access position 136.
[0057] Referring now to FIGS. 18 and 19, a galley cart storage
system 158 includes a lower cart group 160 and an upper cart group
162. Upper cart group 162 occupies a volume of overhead area 44,
similar to previous embodiments. The difference between galley cart
storage system 158 and previous embodiments is that galley carts 38
are stored in galley cart storage system 158 in a generally
fore/aft direction and are therefore not confined within the
envelope of a galley area. A centerline of each galley cart 38 of
upper cart group 162 is aligned with aircraft centerline 46, shown
and described in reference to FIG. 2. Galley carts 38 are raised or
lowered to or from upper cart group 162 using a cart lift 164. FIG.
19 shows that galley carts of upper cart group 162 are divided into
two subgroups, including an upper aft cart group 166 supported by a
first track section 168 and an upper forward cart subgroup 170
supported by a second track section 172. Galley carts 38 stored in
galley cart storage system 158 are configured in a side-by-side
arrangement to maximize the number of galley carts which can be
stored in each cart subgroup.
[0058] When a galley cart 38 is lifted by cart lift 164, it first
reaches a transfer area 174. From transfer area 174, galley carts
138 are translated in either an aft transfer direction "N" and onto
first track section 168, or in a forward direction "O" and
supported by second track section 172. Because of the configuration
of both upper aft cart subgroup 166 and upper forward cart subgroup
170, galley carts 38 stored in either of these subgroups are
positioned in a first in/last out configuration. For example, an
aft end cart 176 and a forward end cart 178 are the first carts
loaded in either subgroup 166 or 170, respectively. Aft end cart
176 and forward end cart 178 are therefore the last carts removed
from either of these subgroups. As shown in FIG. 18, galley cart
storage system 158 also includes a standard galley portion 15
positioned on an opposed side of a passageway from lower cart group
160. First track section 168 extends above standard galley portion
15 and second track section 172 extends above a passenger seating
area (not shown).
[0059] Referring to FIG. 20, cart storage system 144 is shown
installed on passenger deck 30. In order to access individual
storage carts positioned in elevated locations when a transport
system is out of service, a plurality of access panels 180 are
provided. At least one of the galley carts 38 stored in any
elevated position can be removed through one of the access panels
180 by manually removing the access panel and manually removing the
cart. FIG. 20 further shows an exemplary control panel 182. Control
panel 182 is used to control the transport system to raise or lower
a galley cart from a predetermined storage position or from a first
in/last out storage position of any of the embodiments of the
present invention. In the exemplary location shown in FIG. 20,
control panel 182 is positioned on an end face of cart storage
system 144, providing personnel access to the controls for the
transport device. Control panel 182 shown in FIG. 20 is exemplary
of a plurality of positions possible for control panel 182. Access
panels 180, shown in FIG. 20, are exemplary of locations for access
panels for personnel standing on passenger deck 30.
[0060] Referring finally to FIG. 21, the operations to load a
galley cart for an exemplary embodiment of the present invention
are described. In a first operation 200, a plurality of mobile
carts are grouped into a side-by-side orientation. In operation
202, the mobile carts are divided into at least a first cart group
and a second cart group. Next, in an operation 204, the second cart
group is positioned above the first cart group one of within and
adjacent to the mobile platform galley. In operation 206,
individual mobile carts of the second cart group are automatically
accessed. Finally, in an operation 208, the individual mobile cart
is transferred to an access area in the first cart group.
[0061] Galley cart storage systems of the present invention
generally provide increased galley cart numbers in an improved
galley arrangement that require less passenger cabin floor space,
thus allowing more passenger seating and increased revenue earning
potential. Mobile platforms such as aircraft have galleys which are
fastenably attached to passenger or other deck support structure.
It is desirable to provide galley designs which can be un-fastened
and relocated in their entirety, to modify seating configurations
of the aircraft. Galley cart storage systems of the present
invention are also provided with removable mounts (not shown),
allowing relocation of the entire galley area(s). Galley cart
storage systems of the present invention are generally described
herein in reference to lifting and loading individual galley carts
38. Galley carts 38 can be removed from storage by generally
reversing the lifting and storing operations.
[0062] A galley cart storage system of the present invention offers
several advantages. By locating galley carts in elevated positions
within individual galley areas, the number of galley carts that can
be stored in or adjacent to a galley for a mobile platform is
increased. By providing automatic lift capability, access to galley
carts stored in elevated positions is improved and can be
controlled by a single person. Space previously used in galleys for
additional countertop and/or cabinet storage is converted by the
embodiments of the present invention to galley cart storage,
thereby increasing the efficiency of galley cart storage. By
providing certain embodiments of the present invention with galley
cart storage in areas above galley area passageways, overhead area
volume is advantageously employed which also allows the galley area
to be enlarged without reducing passenger area seating capacity. By
keeping galley cart storage in or immediately adjacent to the
galley area, transfer noise, spillage and maintenance problems
associated with previous system designs are mitigated. By keeping
additional galley carts within the envelope of the galley area,
mobile platforms such as aircraft have the added capability of
relocating the entire galley area, including additional galley
carts located either forward or aft, to modify passenger seating
arrangements.
[0063] While various preferred embodiments have been described,
those skilled in the art will recognize modifications or variations
which might be made without departing from the inventive concept.
The examples illustrate the invention and are not intended to limit
it. Therefore, the description and claims should be interpreted
liberally with only such limitation as is necessary in view of the
pertinent prior art.
