Galley cart storage system and method of use
A mobile platform galley cart storage and retrieval system includes a plurality of joined walls defining a galley area. A plurality of mobile carts are stored in the galley area, including at least a first side-by-side subgroup of carts and a second-side-by-side subgroup-of carts positioned above the first subgroup. An optional third subgroup is positioned above the second subgroup. An automatic transfer system lifts and horizontally transfers carts to predetermined storage locations on racks supporting each elevated subgroup of carts. The carts are stored in either randomly accessible locations or in first-in/last-out locations.
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 INVENTIONMobile 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.
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.
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 INVENTIONAccording 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.
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.
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.
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.
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.
The features, functions, and advantages can be achieved independently in various embodiments of the present inventions or may be combined in yet other embodiments.
BRIEF DESCRIPTION OF THE DRAWINGSThe present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
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.
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.
According to a preferred embodiment of the present invention, and referring to
Referring to
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.
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

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.

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
Referring next to
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.
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.

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

Referring finally to
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.
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.
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.
