Definitions

• the present invention relates to a waste receptacle provided with wheels
• Waste receptacles provided with wheels, and made of thermoplastic material are commonly used nowadays
• One common type of such receptacles is the type which has a principally rectangular cross-section as seen from above, and two or more wheels
• the wheel axle is often arranged near the base and near one of the sides, which side can be named the rear side.
• a lid is often arranged in connection to the upper edge of the rear side
• Such a receptacle is tilted backwards when it is to be moved, rolling on the wheels
• Receptacles as above are, however, very bulky which will obstruct transport This is most often solved by nesting a number of receptacles in one another
• One problem is that the wheels can not be assembled since they will obstruct the nesting
• the user will normally have to assemble the wheels when such a receptacle is delivered This assembly is normally more or less complicated which will lead to an incorrect assembly with a deteriorated function as a consequence
• One solution to this problem could be to arrange the wheels on the inside of the walls, including the rear wall whereby they could be factory assembled This would, however, cause a number of inconveniences since the support area in the bottom of the receptacle would be radically reduced whereby the risk that the receptacle could turn over in connection to windy conditions would increase significantly
• One possible solution to this attendant problem could be to make the wheel diameter smaller
• the receptacle would, however then be more difficult to move, especially in stairs, over thresholds and on soft and uneven ground
• the invention relates to a waste receptacle comprising a base, a rear wall, two side walls and a front wall
• the walls are inclined so that the horizontal cross-section is smaller at the base than at the top of the receptacle
• the receptacle is furthermore provided with wheels arranged at the base, which wheels are used when moving said receptacle
• the receptacle is preferably provided with a lid which is uniform or divided into sections and suitably arranged at the upper end of the rear wall
• the invention is characterised in that the wheels are each attached to one slewing bracket which is provided with a rotation axle and a pivot axle
• the rotation axle forms the rotation axle for the wheel while the pivot axle forms the fulcrum of movement for the slewing bracket
• the rotation axle and the pivot axle are parallel to the rear wall
• the wheels can be moved between a temporary position and a regular position By tilting the receptacle somewhat when the wheels are in the regular position, the receptacle can be moved by being rolled on the wheels Receptacles can be nested into one another when the wheels are in the temporary position
• the wheels are preferably arranged at the rear wall when in the regular position
• the rotation axle of the wheels is suitably parallel to the rear wall and the base when the wheels are located in both the temporary and the regular position
• the wheels are suitably placed inside the vertical extension of the side walls when in both temporary and regular position
• the slewing brackets can preferably be snap-fitted to the surrounding walls in at least the regular position
• the slewing brackets are suitably snap-fitted into the regular position by being provided with at least one rotation axle peg which engages one rotation axle hole each
• the rotation axle hole/holes is/are placed in the surrounding walls
• the snap-fitting is accomplished by forcing the surrounding walls outwards when the rotation axle peg/pegs is/are forced towards guiding wedges at the lower part of the surrounding walls, whereby the surrounding walls snap back when the rotation axle peg/pegs is/are aligned with the rotation axle hole/holes
• the slewing brackets are snap-fitted into the regular position by being provided with at least one axially resilient rotation axle peg which engages one rotation axle hole each
• the rotation axle hole/holes is/are placed in the surrounding walls
• the snap-fitting is accomplished by forcing the rotation axle peg/pegs inwards when it/they is/are forced towards guiding wedges at the lower part of the surrounding walls whereby the rotation axle peg/pegs snaps/snap back when the rotation axle peg/pegs is/are aligned with the rotation axle hole/holes
• Guiding wedges can of course also be placed on the rotation axle peg/pegs
• the slewing brackets for both wheels are suitably connected to each other b ⁇ means of a connecting axle so that the two slewing brackets form a unit
• An increased stability in the wheel suspension is hereby obtained
• the receptacle is preferably also provided with a lid which is provided with operative and stow-away suspension means at the rear end of the lid
• the operative suspension means is intended for a moveable attachment of the lid onto pivot axles at the upper end when the receptacle is used in a normal way
• the lid can hereby be opened and closed
• the stow-away suspension means is used for attaching a lid onto the pivot axles when a number of receptacles are nested in one-another.
• the suspension means are suitably of a snap-on type which considerably facilitates the assembly and disassembly of the lid.
• the lid can hereby easily be attached in both transport/storage position as well as in the use position where the lid can be opened and closed.
