Description
- This invention generally relates to trash compactor systems and particularly to trash compactor systems for aircraft or aerospace vehicles.
- The handling of large amounts of waste material generated during the flight of passenger-carrying aircraft has long presented a major problem to in-flight service personnel. The introduction of wide-bodied jet aircraft with very high density passenger configurations has exacerbated the problem, not only from an in-flight service point of view but also with respect to flight safety. Current methods of waste disposal on board passenger-carrying aircraft include the use of paperboard boxes and plastic bags in conjunction with trash bins or trash carts which require high volume storage areas. Frequently, when the primary trash storage areas are filled, plastic bags or paper bags with plastic inserts are used to collect excess trash. These excess trash containers are frequently stored during the flight in the galley areas on in lavatories, thereby rendering them unusable for passengers, and even behind the last row of passenger seats or in unused passenger seats. Such filled trash containers are not only unsightly, but they also present a serious risk of on-board fire due to the highly combustible nature of the trash and the possibility that ignition sources may have been introduced into the container along with the trash. An additional safety hazard is created when excess filled trash containers are stored in exit areas because these containers may block or impede egress in emergency situations.
- During a typical five-hour flight with statistically average passenger loads on wide-bodied aircraft (e.g., from Hawaii to California or across the continental United States), approximately 20 to 30 cubic feet of trash may be generated. On longer transoceanic routes lasting up to 15 hours, 80 to 120 cubic feet of trash may be generated due to the number of meal, snack, and bar services that are offered.
- The trash compactors now available for residential uses are incapable of handling the large volumes of trash generated on board an aircraft within the time constraints for in-flight service. They have neither the power, the space saving capability, nor the cycle time sufficient to meet the in-flight service requirements.
- For trash compactors to be used on aircraft, they have to be placed within the galley of the aircraft, or in an easily accessible processing location, such as a closet, or have to be fitted onto rolling carts of the same or similar size as the food and beverage carts used on the aircraft. Thus, such compactors would have to be relatively small, lightweight, and be custom configured to fit in the many appropriate installation locations aboard aircraft and space vehicles.
- Commercial or industrial trash compactors now available are much too large and heavy for such uses, and they require electrical power not ordinarily available on the aircraft. An example of one such compactor is provided by that disclosed in US-A-3,861,117 which describes an apparatus for location within restaurants, stores, warehouses, apartment buildings, and the like for shredding and packing refuse into bag-like containers. The apparatus includes a sealing means for sealing the container air-tight to insure that all odours emanating from the refuse are held within it while the container awaits pick-up for disposal.
- The aircraft trash compacting system described in EP-A-0169719 (to the same applicant) represented a substantial advance in the art which preceded it. One aspect of the trash compactor described which was particularly attractive was the double chamber trash compactor wherein a filled trash container might be stored in the rear chamber. However, it was found that the rear panel of the cardboard trash containers were frequently not sufficiently strong to contain the compacting pressure without tearing seams and the like.
- According to the present invention, there is provided a trash compactor comprising a housing provided with an internal chamber having front and rear chamber sections which are adapted to receive trash containers; means to deposit trash in a trash container disposed within the front chamber section; a reciprocating compacting platen which is extendable downwardly into a trash container disposed within the front chamber section to compact trash therein; a movable support wall transversely disposed in the internal chamber between the front and rear chamber sections; means to fix the transverse position of the movable support wall between the front and rear chamber sections to facilitate the support of the rear panel of a trash container disposed within the front chamber section; and means to move the movable support wall from its fixed transverse position to an out-of-the-way position so that a trash container in the front chamber section may be moved into the rear chamber section, characterised in that the means to fix the transverse position of the movable support wall comprises latching means.
- The movable support wall is preferably hingedly connected to one of the sidewalls of the internal chamber dividing this chamber into the front and rear chamber section. The moveable support wall may be mounted so that it will swing into the rear chamber section to allow filled trash containers to be pushed from the front chamber section into the rear chamber section.
- The latching means are preferably provided with a disengaging means which can be operated from the front of the trash compactor
- Upon disengaging the latching means, the movable support wall may be pushed into the rear chamber section simultaneously as a filled trash container is pushed into the rear chamber section for storage or disposal. An empty trash container may then be placed into the front chamber section. The front panel of the filled trash container in the rear chamber section will support the rear panel of the trash container placed in the front chamber section when trash is compacted therein.
- In an alternative embodiment, the rear chamber section is provided with a chute which directs filled trash containers pushed into the rear chamber section to a storage area disposed beneath the flooring supporting the trash compactor. In this embodiment, after the disposal of the trash container down the chute to the storage area the movable support wall is repositioned and fixed transversely in the chamber to provide support for a new trash container placed in the front chamber section. This embodiment is particularly attractive in wide bodied aircraft which have a significant amount of space for the storage of such trash containers beneath the floor of the passenger compartment.
- The present invention provides for a substantially improved trash compactor system, particularly in those situations in which large volumes of trash are generated, such as during the long transcontinental and transoceanic flights of wide bodied jets.
- By way of example, embodiments of the invention will now be described with reference to the accompanying drawings, in which:
- FIG. 1 is a perspective view of a trash compacting system embodying features of the invention;
- FIG. 2 is another perspective view of the trash compactor shown in FIG. 1 with the front door open to show the interior thereof;

- FIG. 6 is a partial side view of the operating mechanism for the latch system shown in FIG. 4;
- FIG. 7 is a top view of the support door shown in FIG. 5 taken along the lines 7-7;
- FIG. 8 is a plan view in section taken along the lines of 8-8 shown in FIG. 3 illustrating the disposition of a filled trash container in the rear chamber section and an empty trash container disposed within the first chamber section; and
- FIGURE 9 is a side elevational view in section of an alternative embodiment wherein a chute is provided in the rear chamber for disposing of trash containers in a storage area beneath the compactor.
- In the drawings, all corresponding parts are numbered the same.
- Reference is made to FIGS. 1-3 which illustrate an improved trash compacting system embodying features of the invention. The
trash compactor 10 generally includes a cabinet 11, afront door 12, atrash chute 13 for dropping trash into the interior of thecompactor 10, and acontrol panel 14 for operating thecompactor 10. - With particular reference to FIG. 2 and 3, the
compactor 10 is provided with an elongatedinternal chamber 15 defined in part byopposing sidewalls 16 and 17, therear wall 18, theinside surface 19 offront door 12, and afloor 20. Theinternal chamber 15 comprises afront chamber section 21 wherein trash is compacted in atrash container 22 disposed therein by a compactor platen orram 23, and arear chamber section 24 wherein filledtrash containers 22 are stored or disposed. The front andrear sections wall 25 which is adapted to support the rear panel of acontainer 22 disposed in thefront section 21 while trash is compacted therein by thecompactor ram 23. - As shown in FIG. 3, the vertically oriented,
movable support door 25 is preferably pivotally mounted ontosidewall 16 by means ofhinges 27 so that it can be pivoted about the vertical axis of thehinges 27 into an out-of-the-way position in therear chamber section 24 to facilitate moving a trash-filledcontainer 22 from thefront chamber section 21 to therear chamber section 24. - As shown in FIGS. 4-7, latching means 30 are provided to fix the position of the
movable support door 25 transversely across thechamber 15 so that thedoor 25 may support therear panel 26 of atrash container 22 disposed within the first chamber section. The latching means 30 generally comprise latch pins orrods 31 which are slidably mounted onto the back side ofdoor 25 by means ofbrackets 32 and are biased toward the sidewall 17, i.e., the closed position, bysprings 33 andcollar 34 which are fixed to therod 31 to urge theend 35 of therod 31 into therecess 36 provided in the sidewall 17. The opposite ends 37 of therods 31 are pivotally mounted tolower cranks 40 bycrank pins 41. Thelower cranks 40 are securely mounted to hingepost 42 by means of locking pins 43 (shown in phantom in FIG. 7). Anupper crank 44 is securely mounted to the upper end ofhinge post 42 in the same manner as thelower cranks 40, but it is mounted at an angle from thelower crank 40. Anoperative arm 45 is pivotally connected to theupper crank 44 at one end thereof bycrank pin 46 and extends to the front of thecompactor 10 where the opposite end thereof is connected to anactuating assembly 47 by means of connectingelement 48. - The
actuating assembly 47, as shown in more detail in FIGS. 5 and 6, generally comprises ahousing 50 and a generally L-shaped handle 51 pivotally connected at one end thereof to connectingelement 48 secured tooperating arm 45. Astrut 52 is pivotally mounted at one end thereof to the center of the L-shaped handle 51 and at the other end thereof is pivotally mounted to abase element 53 inhousing 50. By pulling upwardly on the operatingend 54 of L-shaped handle 51, as shown in phantom in FIG. 6, theupper crank 44 is rotated clockwise by movement of thearm 45 toward the front ofcompactor 10, which in turn causes the clockwise rotation of thehinge post 42 and thelower cranks 40 which are secured thereto. - Upon the clockwise rotation of the
lower cranks 40, the latch pin orrods 31 are pulled toward thehinged margin 55 of thesupport door 25 so as to disengage theends 35 of therods 31 from therecesses 36 provided on the sidewall 17 and thereby release thesupport door 25 from its fixed transverse position so that it is freely rotatable about the axis of thehinge post 42. Thewall 25 may then be easily pushed into an out-of-the-way position in therear chamber section 24 by pushing a filledtrash container 22 infront chamber section 21 into the second chamber. - However, before the filled
container 22 may be pushed into therear chamber section 24, the hydraulicallymovable sidewall panel 56 in thefront chamber section 21 is actuated to release the frictional engagement between thesidewall panel 56 and the adjacentcontainer side panel 57 which builds up during the compaction of trash within thecontainer 22. - To operate the trash compacting system, the
front door 12 of thecompactor 10 is opened, themovable support door 25 is latched into position transversing theinterior chamber 15, perpendicular to thesidewalls 16 and 17 with theends 35 ofrods 31 urged into thereceiving recesses 36 to thereby fix the position of thesupport door 25. Anempty trash container 22 is placed into thefront chamber section 21 of thetrash compactor 10 and thefront door 12 is then closed. The sidewall 17 andsidewall panel 57, the inside ofdoor 12, and themovable support door 25 support the four side panels of thetrash container 22 disposed in the first chamber so that there is no damage to thecontainer 22 during the compaction of trash therein. - The trash is deposited into the
container 22 through openedchute 13, as shown in FIG. 1. When thecontainer 22 is suitably filled with trash thecompactor 10 is actuated by pressing the start button orswitch 60 provided on thecontrol panel 14 to initiate the downward thrust of the compactor platen orram 23 into thecontainer 22. - Upon completion of its compacting stroke, the
ram 23 is automatically retracted from thecontainer 22 into its starting position in the upper portion of thefront chamber section 21, as shown in FIG. 3, so that additional trash may again be deposited into thetrash container 22 through the openedchute 13. After several compacting sequences, thecontainer 22 will be essentially full of compacted trash and will need to be replaced. - To replace the used
trash containers 22 infront chamber section 21, thefront door 12 is opened and theoperative end 54 of the L-shapedhandle 51 is lifted upwardly to thereby disengage the latching mechanism 30 so as to allow for the free rotation of themovable support door 25 to an out-of-the-way position within therear chamber section 24 and the filledtrash container 22 to be pushed simultaneously into therear chamber section 24. A newempty container 22 may then be placed into thefront chamber section 21 and thefront door 12 closed so that trash can again be deposited into thecontainer 22 as previously described. The frontupstanding panel 61 of the filledtrash container 22 in therear chamber section 24 supports therear panel 26 of the empty trash container placed in thefront chamber section 21 in the same manner as thedoor 25. - An alternative embodiment of the present invention is shown in FIG. 9 which involves providing a
chute 62 in therear chamber section 24 which leads to a storage area (not shown) beneath theflooring 63 of the passenger compartment of an aircraft. Thechute 62 directs filledtrash containers 22 which are pushed intorear section 24 to slide downwardly into a storage area beneath theflooring 63 which supports thetrash compactor 10. Atrap door 64 is provided in the floor ofrear chamber 24 to support acontainer 22 therein until it is desired to drop the container down thechute 62. This embodiment is particularly desirable in large, wide-bodied aircraft which have significant space beneath the flooring of the passenger compartments. This embodiment may also reduce the number of trash compactors needed on each aircraft. - It is obvious that modifications can be made, for example, the rear wall of the compactor may include a door for removing trash containers therefrom. Additionally, the movable door or wall which supports the rear panel of the container in the front chamber section may take different forms. for example, a segmented wall may be slidably supported in grooves along the sidewalls of the internal chamber and may be lifted upwardly to be moved to an out-of-the-way position.
