Definitions

  • This invention generally relates to trash compactor systems and particularly to trash compactor systems for aircraft or aerospace vehicles.
  • 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.
  • 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.
  • trash compactors 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.
  • 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.
  • US-A-3,861,117 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • FIGS. 1-3 illustrate an improved trash compacting system embodying features of the invention.
  • the trash compactor 10 generally includes a cabinet 11, a front door 12, a trash chute 13 for dropping trash into the interior of the compactor 10, and a control panel 14 for operating the compactor 10.
  • the compactor 10 is provided with an elongated internal chamber 15 defined in part by opposing sidewalls 16 and 17, the rear wall 18, the inside surface 19 of front door 12, and a floor 20.
  • the internal chamber 15 comprises a front chamber section 21 wherein trash is compacted in a trash container 22 disposed therein by a compactor platen or ram 23, and a rear chamber section 24 wherein filled trash containers 22 are stored or disposed.
  • the front and rear sections 21 and 24 are divided by a movable support door or wall 25 which is adapted to support the rear panel of a container 22 disposed in the front section 21 while trash is compacted therein by the compactor ram 23.
  • the vertically oriented, movable support door 25 is preferably pivotally mounted onto sidewall 16 by means of hinges 27 so that it can be pivoted about the vertical axis of the hinges 27 into an out-of-the-way position in the rear chamber section 24 to facilitate moving a trash-filled container 22 from the front chamber section 21 to the rear chamber section 24.
  • latching means 30 are provided to fix the position of the movable support door 25 transversely across the chamber 15 so that the door 25 may support the rear panel 26 of a trash container 22 disposed within the first chamber section.
  • the latching means 30 generally comprise latch pins or rods 31 which are slidably mounted onto the back side of door 25 by means of brackets 32 and are biased toward the sidewall 17, i.e., the closed position, by springs 33 and collar 34 which are fixed to the rod 31 to urge the end 35 of the rod 31 into the recess 36 provided in the sidewall 17.
  • the opposite ends 37 of the rods 31 are pivotally mounted to lower cranks 40 by crank pins 41.
  • the lower cranks 40 are securely mounted to hinge post 42 by means of locking pins 43 (shown in phantom in FIG. 7).
  • An upper crank 44 is securely mounted to the upper end of hinge post 42 in the same manner as the lower cranks 40, but it is mounted at an angle from the lower crank 40.
  • An operative arm 45 is pivotally connected to the upper crank 44 at one end thereof by crank pin 46 and extends to the front of the compactor 10 where the opposite end thereof is connected to an actuating assembly 47 by means of connecting element 48.
  • the actuating assembly 47 generally comprises a housing 50 and a generally L-shaped handle 51 pivotally connected at one end thereof to connecting element 48 secured to operating arm 45.
  • a strut 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 a base element 53 in housing 50.
  • the latch pin or rods 31 are pulled toward the hinged margin 55 of the support door 25 so as to disengage the ends 35 of the rods 31 from the recesses 36 provided on the sidewall 17 and thereby release the support door 25 from its fixed transverse position so that it is freely rotatable about the axis of the hinge post 42.
  • the wall 25 may then be easily pushed into an out-of-the-way position in the rear chamber section 24 by pushing a filled trash container 22 in front chamber section 21 into the second chamber.
  • the hydraulically movable sidewall panel 56 in the front chamber section 21 is actuated to release the frictional engagement between the sidewall panel 56 and the adjacent container side panel 57 which builds up during the compaction of trash within the container 22.
  • the front door 12 of the compactor 10 is opened, the movable support door 25 is latched into position transversing the interior chamber 15, perpendicular to the sidewalls 16 and 17 with the ends 35 of rods 31 urged into the receiving recesses 36 to thereby fix the position of the support door 25.
  • An empty trash container 22 is placed into the front chamber section 21 of the trash compactor 10 and the front door 12 is then closed.
  • the sidewall 17 and sidewall panel 57, the inside of door 12, and the movable support door 25 support the four side panels of the trash container 22 disposed in the first chamber so that there is no damage to the container 22 during the compaction of trash therein.
  • the trash is deposited into the container 22 through opened chute 13, as shown in FIG. 1.
  • the compactor 10 is actuated by pressing the start button or switch 60 provided on the control panel 14 to initiate the downward thrust of the compactor platen or ram 23 into the container 22.
  • the ram 23 Upon completion of its compacting stroke, the ram 23 is automatically retracted from the container 22 into its starting position in the upper portion of the front chamber section 21, as shown in FIG. 3, so that additional trash may again be deposited into the trash container 22 through the opened chute 13. After several compacting sequences, the container 22 will be essentially full of compacted trash and will need to be replaced.
  • the front door 12 is opened and the operative end 54 of the L-shaped handle 51 is lifted upwardly to thereby disengage the latching mechanism 30 so as to allow for the free rotation of the movable support door 25 to an out-of-the-way position within the rear chamber section 24 and the filled trash container 22 to be pushed simultaneously into the rear chamber section 24.
  • a new empty container 22 may then be placed into the front chamber section 21 and the front door 12 closed so that trash can again be deposited into the container 22 as previously described.
  • the front upstanding panel 61 of the filled trash container 22 in the rear chamber section 24 supports the rear panel 26 of the empty trash container placed in the front chamber section 21 in the same manner as the door 25.
  • FIG. 9 An alternative embodiment of the present invention is shown in FIG. 9 which involves providing a chute 62 in the rear chamber section 24 which leads to a storage area (not shown) beneath the flooring 63 of the passenger compartment of an aircraft.
  • the chute 62 directs filled trash containers 22 which are pushed into rear section 24 to slide downwardly into a storage area beneath the flooring 63 which supports the trash compactor 10.
  • a trap door 64 is provided in the floor of rear chamber 24 to support a container 22 therein until it is desired to drop the container down the chute 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.
  • the rear wall of the compactor may include a door for removing trash containers therefrom.
  • the movable door or wall which supports the rear panel of the container in the front chamber section may take different forms.
  • 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.
