Definitions

  • This invention relates to a rotatable base assembly and in particular to a rotatable base assembly for supporting waste containers.
  • the present invention also relates to a waste container incorporating or associated with a rotatable base assembly.
  • Containers for containing refuse or waste are in many different configurations.
  • the containers are mobile containers provided on one side of their base with a pair of wheels and gripping handles above the wheels which enables a container to be gripped, tipped towards the wheels so as to be supported thereby and wheeled to a desired location where the container is usually stored or to a location where the container can be left to be engaged by a refuse or waste collection vehicle for elevation and tipping so that the contents of the container are discharged into a collection hopper.
  • Containers of this type are also provided with a hinged lid with the hinge axis being located substantially parallel to the axis of the wheels and adjacent the gripping handles and with handles for the lid being provided on the side of the lid opposite the container gripping handles.
  • Refuse or waste containers of this type are commonly known as “wheelie” bins.
  • bins provide a convenient means by which household refuse or the like can be deposited and then collected and removed from premises however they are relatively bulky and therefore they occupy a substantially space.
  • access to the bins is often difficult. For example, where the bins are wheeled into a confined space such as against a wall where they are normally left, it is difficult for person wishing to deposit waste into the bins to reach the lid handles and lift the lid as the lid handles are on the far side of the bin.
  • the bin is to be positioned so that the lid is easily accessible, that is so that the lid handles are on the near side, it is often difficult to move and manipulate the bin into a convenient position whilst ensuring that refuse or waste does not spill from the bin or the bin does not tip over. This thus creates a hygiene and safety problem.
  • Manipulation of the bin is particularly difficult where the texture of the surface on which the bin is located is loose such as a gravel or earth surface as the wheels tend to dig into the surface.
  • the present invention aims to provide in one aspect a rotatable base assembly for refuse or waste containers, which overcomes or alleviates one or more of the above disadvantages.
  • the present invention in a further aspect aims to provide in combination a refuse or waste container and rotatable base assembly.
  • the present invention thus provides in a first aspect a rotatable base assembly for a single waste container of the type having a pair of opposite wheels by which said container may be wheeled when tipped, said base assembly having a platform and a base, said platform being supported on said base for rotation about a substantially vertical axis, said platform having an upper surface and a front and a rear, an entry/exit at the front of said platform through which a said waste container may be moved wholly onto said platform or moved from said platform, and means for constraining said waste container on said platform, said constraining means including means on said platform for receiving said wheels of said waste container for locating said container on said platform whereby a waste container supported on said platform may be rotated with said platform about said vertical axis.
  • the waste containers also have a chamber and manipulating handles located at an upper end of the chamber above the wheels.
  • a lid is hinged to the chamber adjacent the manipulating handles for movement about an axis extending substantially parallel to the wheel axis and the lid is provided with handles remote from the hinge axis of the lid.
  • the upper surface of the platform comprises an upper substantially planar surface to receive and support the base of a waste container.
  • the constraining means may comprise one or more ribs or ridges extending upwardly relative to the planar surface.
  • ribs or ridges may be provided on opposite sides of the platform.
  • the locating means for the wheels may comprise recesses defined by the ribs or ridges into which the wheels may be moved to locate the waste container on the platform.
  • the rib or ridges may converge towards each other from the front to the rear of the platform.
  • the constraining means may also include a rib or ridge located at the rear of the platform which acts as a stop to the waste container.
  • the front of the platform however most preferably is free of a rib or ridge to enable the waste container to be readily moved onto the platform.
  • the ribs or ridges may define a platform area substantially complementary to the cross section of the container at and including the wheels.
  • Pivot means between the platform and base suitably define the vertical axis about which the platform may rotate relative to the base.
  • the pivot means may comprise axle means adapted to be located in aligned apertures arranged centrally in the platform and base.
  • the axle means in one form may comprise a pin.
  • the pin may inserted through the apertures in the platform and base and positively engage with the base.
  • the pin may have a head end and a shank which is inserted through the apertures in the platform and base.
  • the pin snap engages with the base to positively secure the platform to the base.
  • the pin shank may have a leading barbed end for snap engagement with the base.
  • bearing means are provided between the platform and base to support the platform on the base.
  • the bearing means are preferably located at a radial spacing from the centre of the platform and base.
  • the bearing means are supported on one of the platform and base and cooperate with an annular track on the other of the platform or base.
  • the bearing means are supported on the platform and cooperate with an annular track provided on the base.
  • the bearing means most suitably comprise a plurality of bearings.
  • the bearings may in one form comprise rollers mounted for rotation about axes extending radially from the centre of the platform or base.
  • the rollers may have axles which engage with axle holders on the underside of the platform.
  • the bearings may comprise ball bearings.
  • the ball bearings may be supported in complementary part spherical recesses in the platform or base for cooperation with a track in the base or platform respectively.
  • the present invention provides a rotatable base assembly for a waste container of the type having a waste chamber, wheels at the bottom of and on one side of said chamber and a lid hinged to said chamber for movement about a hinge axis on said one side of said chamber and above said wheels, said base assembly comprising a platform and a base for said platform, said platform being supported for rotational movement about a substantially vertical axis to said base, pivot means interconnecting said platform and said base and defining said vertical axis of rotation of said platform, said platform having an entry/exit and being rotatable between a first position in which said waste container may be moved wholly onto said platform through said entry/exit to a position over said pivot means or moved from said platform through said entry/exit and a second position in which said container and platform are rotated about said vertical axis such that said container is constrained from movement to or from said platform and said platform including means for locating said waste container on said platform, said locating means including means for receiving said wheels of said container.
  • the second position is approximately 180° from the first position however the second position may be at any angular position relative to the first position.
  • the second position may also be in either rotational direction from the first position.
  • the waste container may be constrained from movement to or from the platform by ribs or ridges on the platform.
  • the platform may be alternatively formed to constrain movement of the waste container from the platform.
  • the entry/exit region may be bounded at least on opposite sides by the ribs or ridges.

  • the surface 13 of the platform 11 is supported on its underside by a series of stiffening ribs or flanges 19 including pairs of diagonally extending parallel ribs or flanges 20 between which respective supporting wheels 21 may be located, the axes 22 of the wheels 21 lying along lines extending radially from the centre of the platform 11 .
  • the wheels 21 are provided with axles 23 , the ends of which extend from opposite ends of the wheels 21 .
  • Pairs of forked ribs 24 extend between the pairs of diagonal ribs 20 at the same radial spacing from the centre of the platform 11 into which opposite ends of the axles 23 may snap engage such that the wheels 21 are secured releasably to the underside of the platform 11 .
  • the platform 11 is further provided at its centre with a circular opening 25 to receive an axle pin 26 , the shank of which has at its leading end an enlarged barb 27 which is spit radially and which is adapted to secure the platform 11 to the base 12 .
  • the base 12 is of a circular configuration in plan view and includes on its upper side an outer annular substantially planar track 28 supported by integrally formed radially extending ribs 29 to a central hub 30 .
  • An intermediate annular member 31 is provided between the track 28 and hub 30 .
  • a series of stiffening ribs or flanges 32 are provided on the underside of the track 28 , member 31 and hub 30 to provide sufficient stiffness to the base 12 to resist loadings applied by a waste container supported on the platform 11 and through the wheels 21 on the base 12 .
  • the hub 30 is centrally apertured at 33 to receive the barbed end 27 of the axle pin 26 which may snap-lock into the aperture 33 to positively retain the platform 11 to the base 12 but permit rotational movement of the platform 11 relative to the base 12 about a substantially vertical axis defined by the axle pin 26 .

  • the assembled rotatable base assembly 10 is positioned in a substantially horizontal attitude on the ground where the waste container 36 is usually located.
  • the platform 11 is rotated such that the open front 17 thereof is directed outwardly.
  • the waste container 36 is then wheeled into a position in alignment with the base assembly 10 and tipped rearwardly about its wheel axle 39 such that its leading end is raised and can be moved through the open front 17 onto the platform 11 as illustrated in FIG. 7 .
  • Further forward force applied to the container 36 in the direction B will cause the bottom 43 of the container 36 to seat substantially flat on the platform 11 which then slides forwardly to the position of FIG.
  • the container 36 is fully supported on the platform 11 with the wheels 38 locating within the recesses 18 which prevents further forward movement of the container 36 .
  • the container 36 may be guided onto the platform 11 by contacting the ribs or ridges 14 and the leading end of the container 36 may contact the ridge 16 at the front of the platform 11 which acts as a stop.
  • the container 36 and platform 11 may then be rotated relative to the base 12 (in this case clockwise) from the position of FIG. 8 , through the position of FIG. 9 to the position of FIG. 10 where the container 36 and platform 11 are in a position approximately 180° from the position of FIG. 8 .
  • the handles 42 of the lid 41 are located on the near side adjacent to the user and are thus readily accessible enabling them to be grasped to lift the lid 41 for deposit of waste 44 into the chamber 37 as shown.
  • the container 36 and platform 11 are rotated back to the position of FIG. 8 where the gripping handles 40 are adjacent the user.

  • the base assembly 45 includes a base 46 similar to the base 12 and a platform 47 supported on the base 46 for rotation about a substantially vertical axis in a similar manner to the support of the platform 11 on the base 12 .
  • the platform 47 in this case has a planar container supporting surface 48 bounded on opposite sides by upstanding side ribs or ridges 49 which converge towards each other from the front 50 of the platform 47 to the rear 51 thereof.
  • the ribs or ridges 49 are indented adjacent the front 50 of the platform 47 which increase the width of the platform 47 adjacent the front 50 thereof and defines opposite wheel recesses 52 in which the wheels 38 of the container 36 may locate.
  • the supporting surface 48 of the platform 47 defined between the ribs 49 is substantially complementary to the cross sectional shape of the lower portion of the waste container 36 which may be supported on the platform 47 such that it can be located neatly and securely on the platform 47 .
  • the rotatable base assembly 45 is used in a similar manner to that described with reference to FIGS. 7 to 10 with in this case, the waste container 36 when located on the platform 46 being neatly and closely received between the complementary shaped side ribs or ridges 49 . Further, the converging nature of the side ribs or ridges 49 and/or the recesses 52 for the container wheels 38 permits the container 36 to be loaded onto the open front 50 of the platform 47 only and not be pushed off the rear of the platform 47 .
  • the rotatable base assembly may be formed of plastics suitably injection moulded plastic typically recycled plastics but may be formed of metals or other materials.
  • the base assembly being relatively thin may be easily stacked flat for shipping and handling thereby saving costs.
  • the base assembly has a height of approximately 70 mm to enable easy transfer of the waste container to and from the platform however this dimension may vary.
  • the rotatable base assemblies allows the consumer to rotate a waste container supported thereon with little effort using just one hand and consumers are not required to touch the bin in any area that might be unhygienic. No change is required in the design of conventional “wheelie” bins which are commonly in use as waste containers.
  • base assemblies 10 and 45 are most suited for use with containers 36 of a size which will neatly locate on the platforms 11 and 47 , they may be used with smaller size containers which will simply sit on top of the platforms 11 and 47 .
  • the bases 12 and 46 are of a generally circular configuration however they may be of square configuration in plan view or of any other shape.
  • the base 12 of the assembly 10 of FIGS. 1 to 6 may be substantially identically to the platform 11 such that only a single mould is required for both components.
  • the pin 26 for retaining the platform to the base most preferably is formed of plastics but may be formed of metal. In some cases also, a bearing or bush may be provided between the pin 26 and platform and/or base.
  • the platform in the described embodiment is supported by rollers to the base which effectively act as bearings transferring load from the platform to the base.
  • the rollers may be in other forms that than illustrated such as in the form of spherical rollers located within part spherical recesses on the under side of the platform.
  • the rollers or other bearings may be supported in a fixed position on the base and cooperate with an annular track provided on the underside of the platform.
  • the base assembly Whilst the rotatable base assembly is described to be a separate unit upon which a waste container can be seated, the base assembly may be manufactured as part of the waste container as shown in FIG. 13 .
  • the bottom 43 of the waste container 36 in such an embodiment may comprises the platform of the base assembly being supported for rotation by a pivot pin 52 about an axis extending longitudinally to the container chamber 37 to the base 53 , the axis being substantially vertical when the container is in a normal position to accept waste.
  • the waste container 36 may be rotated about a vertical axis but when tipped as in FIG. 7 , the base 53 will be lifted from the ground with the chamber 37 allowing the container 36 to be wheeled.
  • the base may be a separate component with which the bottom 43 of the chamber 37 may engage for rotational movement. In this case, when the container 36 is tipped, the chamber 37 will disengage from the base 53 which remains on the ground.
