Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an apparatus for collecting waste items prior to collection and delivery for recycling. More particularly, the present invention relates to collection of waste items created as a consequence of transport catering. In greatest particularity, the present invention relates to an apparatus for use in aircraft, coaches and trains. 
       BACKGROUND TO THE INVENTION 
       [0002]    Passenger aircraft, and even cargo aircraft, even on short to medium haul flights, provide food and refreshment for the passengers and crew . The result of such activity is to create waste in many forms, including, but not limited to: food; plates: cutlery: crockery; paper waste of all kinds; bottles; and plastic items of all kinds. In current aircraft practice, all types of waste items are disposed of in the same bag or binliner resulting in all of the different types of item being mixed and thereby rendered unsuitable for recycling. 
         [0003]    In the recent years recycling has become more popular throughout the world. In the United Kingdom, the government has encouraged councils to increase facilities to allow the recycling of waste. Current practice of airlines in the United Kingdom, is to have all waste and rubbish disposed of in the same one or more bags or binliner that is (are) then collected by a commercial contractors. The rubbish is later destroyed or placed in landfill sites with different types of waste all mixed up together. The present invention seeks to avoid such waste item mixing when disposing of waste in passenger transport situations. 
         [0004]    Airlines in Spain and some northern European countries recycle waste from their flights. The present invention seeks to provide an apparatus that simplifies the organisation and operation of such recycling. 
         [0005]    Catering on trains and in motorised coaches very closely resembles aircraft catering. The present invention also seeks to provide an apparatus suitable for providing recycling in trains, motorised coaches, and any other type of passenger transport vehicle such as, but not limited to, ships and hovercraft and even for static catering situations such as canteens and restaurants. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention consists in a rubbish collection trolley comprising:
       a removable horizontal tray removeably insertable into the body of the trolley and comprising a plurality of horizontally adjacent apertures;   a plurality of rubbish bags each disposable one in each aperture;   and   an independently insertable and removable liquid waste container for receiving liquid waste.       
 
         [0011]    The invention further provides that the rubbish bags can be held within the removable horizontal tray prior to use; and that the rubbish bags can be freed to hang vertically within the trolley when in use. 
         [0012]    Invention also provides that the apertures can be colour coded according to the type of waste the associated rubbish bag is to contain and according to the colour code employed in the particular country where recycling is to occur. 
         [0013]    The invention also provides that the rubbish bags can be colour coded according to the waste each type of bag is to contain and according to the colour code employed in the particular country where recycling is to occur. 
         [0014]    The invention also provides that the liquid waste container can be removable from the tray in the trolley for emptying and replaceable into the tray in the trolley without requiring removal of rubbish bags. 
         [0015]    The invention also provides that the trolley can comprise a retractable lid adapted to be movable to be retracted into the trolley when the trolley is in use and adapted to the movable to cover the horizontal tray when the trolley is not in use. 
         [0016]    The invention also provides that the trolley can be used in at least one of: an aircraft; a ship; a hovercraft; a train; and a building, and when adapted for use in an aircraft, is conformal with a standard aircraft trolley, in which case the removable horizontal tray can comprise six apertures. 
         [0017]    Invention also provides that the trolley can comprise a door, the door being closable to secure the horizontal tray within the trolley.

     DETAILED DESCRIPTION 
       [0043]    The invention relates to a specifically designed trolley to collect and separate rubbish to allow easily recycling on aircraft. The trolley can also to be adapted for ships and trains or for use at other suitable venues such offices, private houses or any large gathering of people. The trolley allows the quick and easy separation of waste on an airplane to permit recycling at a hub station. 
         [0044]    In the embodiment described below, the trolley is conformal with a standard aircraft trolley and consists in a standard aircraft trolley with specific modification to the top of the trolley. Specifically, the modifications allows for a tray to be inserted from the outside to the inside on the top of the trolley from the swing door via sliding motion. 
         [0045]    Attention is first drawn to  FIG. 1 , showing an angled overall view of an exemplary trolley suitable for use in the invention. 
         [0046]    An exemplary trolley  2  comprises a retractable lid  6 . The retractable lid  6  is shown in  FIG. 1  in a closed position. The trolley  2  also comprises a front door  3  having a door handle  8  and a lock  7 . A stop pedal  9  can be used to brake rubber wheels  1  and a release pedal  10  can be used to release the rubber wheels  1 . 
         [0047]    In the example given, for recycling waste in aircraft, the trolley illustrated in  FIG. 1  is a standard aircraft trolley of a rectangular shape with resin panels  4  with four rubber wheels  1  with two wheels  1  at the front and two wheels  1  at the back. The twin pedal  9   10  brake system at the front of the trolley can be pushed up and down to stop and release the brakes. 
         [0048]    Attention is next drawn to  FIG. 2 , showing an angled view of the trolley  2  of  FIG. 1  with the door  3  and lid  6  open. In  FIG. 2  the retractable lid  6  is shown in an opened position, with an inside door panel  4  provided on the inside of the door  3 . The door  3  is supported on the trolley to by door hinges  5 . Rim support  11  is provided for the retractable lid  6  by a plurality of spaced support ledges  11  upon which the retractable lid  6  rests when closed. A panel area  12  is provided within the back panel of the trolley  2  that accepts and retains the retractable lid  6  when the retractable lid is in the fully retracted position. 
         [0049]    Attention is next drawn to  FIG. 3 , a partial view of the trolley of  FIGS. 1 and 2  showing the handle of the retractable lid  6  fully retracted. Attention is also drawn to  FIG. 4 , a view of detail A from  FIG. 3  showing a close up of the support edge for the retractable lid  6  as defined by a plurality of horizontally spaced support ledges  11  where on the retractable lid  6  rests when closed. Attention is further drawn to  FIG. 5 , a view of detail B from  FIG. 3 , showing a close-up of the retractable lid  6  support ledge  11  rim and of the retractable lid  6  stowed inside the back panel  12  of the trolley  2 . 
         [0050]    Unlike pre-existing standard aircraft trolleys, the rubbish collector trolley  2  of the present invention has a full length retractable lid  6  on its top adapted to sit on top of a rim consisting of a plurality of horizontally spaced support ledges  11 . When the retractable lid six is lifted 90 degrees it can be retracted into the inside of the back of the trolley  2  to be stored inside the panel  12  away from rubbish bags  19   20  (see  FIGS. 15 ,  16 ,  22  and  23 ). 
         [0051]    In the retracted position, only a handle at its top edge is exposed, as shown in  FIG. 3 . This leaves the top of the trolley  2  completely open allowing maximum use of the area unlike pre- existing trolleys that have only a one small central hole. 
         [0052]    Attention is next drawn to  FIG. 6 , a partially exploded view showing a tray base outside the trolley. In  FIG. 6 , a tray base  14  is shown outside the trolley  2  having been removed from or yet to be inserted into a tray slide  13 . The tray base  14  comprises six compartments (in this example) for rubbish. The tray base also comprises a rim (not shown) adapted to fit into the tray slide  13  to enable it to be inserted into and withdrawn from the trolley  2 . 
         [0053]    Attention is next drawn to  FIG. 7 , a view of  FIG. 6  showing the tray base  14  inside the trolley  2 . The tray base  14  is slid into the tray slide  13  to but a of the inside the trolley  2 . The inserted tray base  14 , held in the tray slide  13 , rests below the support ledge  11  rim. 
         [0054]    Attention is next drawn to  FIG. 8  showing an elevation the trolley in front view. When the retractable lid  6  is fully closed as shown, the door  3  is also closed as shown and the tray base  14  is inserted, the tray base  14  is concealed from view and sealed from the immediate environment. 
         [0055]      FIG. 9  shows an elevation of the trolley  2  in cross sectional view cut by the plane CC of  FIG. 8  with the retractable lid  6  stored inside. Attention is also drawn to  FIG. 10  that shows detail D of  FIG. 9  providing a close-up of the spaced support ledge  11  rim for retractable lid  6  and the tray slide  13  for tray base  40 . Attention is further also drawn to  FIG. 11  shows detail E of  FIG. 9  providing a close up of the retractable lid  6  retracted inside the panel area  12 . 
         [0056]    Attention is next drawn to  FIG. 12 , showing a front view of the tray base  14  and a tray cover  18 . Attention is also drawn to  FIG. 13  showing a view from above of the tray  14  with compartments. Attention is further drawn to  FIG. 14  shows a sectional view of tray base  14  and tray cover  18  (see  FIG. 15  and  FIG. 16 ) locked together. 
         [0057]    The tray comprises two parts, a tray base  14  and tray cover  18 . Rubbish bags  19   20  (shown in  FIG. 15 ) are held between the tray cover  18  and tray base  14 . The tray base  14  and tray cover  18  can be locked together by an interlocking mechanism with the rubbish bags  19   20  secured there between, as shown in  FIG. 16 . Each rubbish bag  19   20  (shown in  FIG. 15 ) can be folded over edges  22  of a respective aperture of the tray base  14  and held in place and secured by the tray cover  18  (see  FIGS. 15 and 16 ) so when a rubbish bag  19   20  starts to fill, it is restrained from falling inside the trolley  2 . In use, waste items are collected into individual rubbish bags  19   20 , each rubbish bag  19   20  being designated to contain a selected type of waste content. 
         [0058]    Attention is next drawn to  FIG. 15 , showing an exploded view of the tray sections and components illustrating the dispositions of the tray base  14  bearing folded rubbish bags  19   20 , tray cover  18  and recycled plastic liquid waste container  21 . Attention is also drawn to  FIG. 16  showing the tray sections of  FIG. 15  assembled together with the removable liquid waste container  21  inserted and ready for use.  FIG. 16  shows the liquid waste container  21  inserted in the tray base  14  ready to receive liquid waste.  FIG. 15  shows how the liquid waste container  21  can be removed from the rack independently of other bags  19   20 . 
         [0059]    The tray assembly  14   18   19   20   21  is preferably prepared and supplied with bin liners/rubbish bags  19   20  already in situ to save cabin crew rubbish bag  19   20  installation time. 
         [0060]    Attention is next drawn to  FIG. 17  showing a plan view of the assembled tray of  FIG. 16 . Attention is also drawn to  FIG. 18  showing a cross sectional view of the assembled tray along the line GG of  FIG. 17 . Attention is further drawn to  FIG. 19 , showing a close-up detailed view of highlight H of  FIG. 17 . In  FIG. 19 , the tray base  14  presents a tongue and groove joining assembly with the tray cover  18 , the liquid waste container  21  is accepted into grooves in the tray cover  18 . 
         [0061]    Attention is next drawn to  FIG. 20 , illustrating how a tray assembly can be inserted into the trolley  2 . The rubbish bags  19   20  are shown in  FIG. 20  still in their “not let down” condition. The liquid waste container  21  is shown inserted into its position, although, as will be understood, it can be inserted later. The door  3   4  is open to accept insertion of the tray assembly  14   18   19   20   21 . 
         [0062]    Moving to  FIG. 21 , showing the next stage on from  FIG. 20  in assembly of the tray assembly  14   18   19   20   21  into the trolley  2 , the tray base  14  is inserted to lie within the tray slide  13  (as shown in  FIGS. 6 and 10 ). 
         [0063]    Moving to  FIG. 22 , showing a further stage in assembly of the tray assembly  14   18   19   20   21  within the trolley  2 , the rubbish bags  19   20  are then let down to lie within the trolley  2 . The ends of the rubbish bags  19   20  are clear of the inside of the base of the trolley  2 . 
         [0064]    Finally, attention is drawn to  FIG. 23  showing an elevation of the front of the trolley  2  with the door  3   4  open, illustrating the dispositions of the rubbish bags  19   20 . 
         [0065]    The tray assembly  14   18   19   20   21  is held by the rim  13  which supports the tray base  14 . The tray assembly  14   18   19   20   21  is thereby suspended to allow the rubbish bags  19   20  to unfold inside the trolley  2  for the collection of different types of rubbish. 
         [0066]    The door  3   4  can then be closed. The retractable lid  6  can also be closed until the trolley  2  is ready to receive waste. The liquid waste container  21  is smaller in vertical extent than the let-down rubbish bags  19   20  as the weight of liquid waste is very great even in small volumes, making removal and emptying of the liquid waste container  21  a difficult task if the liquid waste container  21  is made too large. Further, the liquid waste container is likely to require emptying at frequent intervals. In use, the liquid waste container  21  can be independently removed from the trolley  2  by opening the door  3   4 . Liquid waste can them be disposed of in any normal way that other liquid waste would be disposed of in that form of transport. Generally speaking, liquid waste can be jettisoned and/or emptied upon arrival. When the door  3   4  is closed the tray assembly  14   18   19   20   21  is fixed into place and unable to move relative to the trolley  2 . 
         [0067]    The liquid waste container  21  can be used, for example, to receive unwanted ice and hot/cold drinks left by passengers which can be emptied therein. The liquid waste container  21  is also provided with a handle enabling the liquid waste container  21  to be removed and emptied then put back into position in the trolley  2 . 
         [0068]    The door  3   4  must be shut from the handle  8  and locked using the lock  7  to fix the tray assembly  14   18   19   20   21  position. Recycling of any material/rubbish will only be from the top of the trolley  2  with the retractable lid  6  open. 
         [0069]    In the example shown, the door  3  is fitted to one side of the trolley  2  by four hinges  5 . The invention also allows for any other means of attachment for the door  3 . 
         [0070]    In the example shown is specifically for use in aircraft, and provides a maximum of six compartments. These are coloured coded according to the product waste and the country where the trolley  2  will be used. It is also to be appreciated that the rubbish bags  19   20  can also be colour-coded according to the custom of the recycler. It is to be appreciated that a number other than six rubbish bags  19   20  can be employed with the invention. It is preferred that the rubbish bags  19   20  are transparent to conform with airline requirements. Transparent rubbish bags  19   20  are also a requirement in many other situations. 
         [0071]    In use, cabin crew will fill the rubbish bags  19   20  during a flight. At the end of the flight the full bags  19   20  be tied and then taken away by the cleaning company that operates on the aircraft (these cleaning contractors already remove waste from the aircraft). 
         [0072]    In the event of one or more of the rubbish bags  19   20  becoming fall, the aircrew can remove an existing full tray assembly (minus the liquid waste container  21 ) and replace it with a fresh tray assembly  14   18   19   20  with the rubbish bags  19   20  not yet let down. 
         [0073]    The present invention provides an environmental, material saving and energy saving advantage. Recycling of materials reduces energy requirements in provision of new materials. Reduction in dumping or burning provides a clear environmental improvement. Instead of disposing of all waste and rubbish in one rubbish bag  19   20  or binliner, a system is provided for use on board and aircraft (or ship, a train etc) to divide the rubbish according to its type. This precaution avoids a problem found when all rubbish its mixed together that some or all of the waste cannot be recycled because contamination. 
         [0074]    Use of the rubbish disposal trolley  2  allows for easy and speedy separation of different types of rubbish accordingly to their type e.g. plastic, paper, cans, metallic items, glass or food, thereby allowing airlines and other passenger transport vehicles, as well as all manner of catering establishments to recycle items expeditiously. 
         [0075]    The trolley  2  is, for preference, made from resin and recycled aluminium in order to remain lightweight and also to be environmentally friendly. The tray sections  14   18 , together with the hard plastic liquid waste container  21  are preferably made from recycled plastic for the same reasons. It is to be understood, that within the invention as claimed, other materials may be used. In non-aircraft use, heavier materials are possible. 
         [0076]    For preference, rubbish bags  19   20  are made from recycled biodegradable polyethylene. 
         [0077]    Those skilled in the art will be aware of modifications and variations that can be applied to the invention as described without deviating from the invention as claimed. 
         [0078]    The invention is further defined by the following appended claims.
