DETAILED DESCRIPTION

Figures 1 to 4 depict a sink arrangement 10 from various angles. The sink arrangement comprises a bowl 12, a waste outlet fitting 20, a grating 60 and a splashback 70 assembled together as an exemplary embodiment e.g. when mounted to a wall. The grating 60 is attached to the splashback 70 by hinge arrangements 80 that allows the grating to be pivoted between a lowered and a raised position. In the lowered position, the grating comes to rest against the edge of the bowl 12 and allows it to be used for e.g. placing buckets that drains into the bowl. When the grating is in its raised position, the grating rests against the splashback or against the wall/surface to which the sink arrangement 10 is mounted. This is achieved by the pivot axis 83 of the grating being arranged at a distance P from the splashback allowing gravity to work as a retaining force making sure the grating does not fall down from its raised position. The grating can also be locked in its raised/lowered position by mechanical means for locking e.g. a locking mechanism, chain, magnet, clip etc.

The hinge arrangements 80 for the grating are attached to the splashback 70 by e.g.

soldering or gluing or riveting or any other suitable fastening means. The hinge

arrangements 80 further comprises fastening pins 81 which includes through holes 82 that are aligned with corresponding holes in the splashback 70 for allowing easy and secure mounting of the sink arrangement 10 and reducing the amount of holes needed in the sink arrangement 10. The fastening pins 81 may have a cylindrical, cuboid or any other shape that enables the grating 60 to be attached in a hinged way and that the fastening pins 81 can function as a support for the sink arrangement 10. By attaching the hinge arrangements 80 to the splashback 70 instead of the bowl as in prior art, the edge of the bowl is easier to keep clean with no attached items around which water or waste can gather and generate sediments. For improved logistics and simplified mounting of the grating and splashback unit 13, the grating fasteners 80 are attached to the splashback 70 as a part of the manufacturing process allowing the splashback 70 and hinged grating 60 to be handled as a unit 13. This grating and splashback unit 13 may be assembled and packed before storage, transport or delivery to end user/customer for the end assembly of the whole sink arrangement 10.

To achieve a design of the sink arrangement 10 that facilitates stable holding of the sink arrangement, that is easy to assemble and easy to mount, the waste outlet fitting 20 is provided with a waste receiving part 30 and integrated supporting members 40. This allows the waste outlet fitting to be a structurally important part of the sink arrangement and reduces the amount of parts in the entire sink assembly. This eliminate, e.g. a separate bracket as in prior art and associated fastening means, such as screws, for attaching the bracket to the waste outlet fitting 20. The waste outlet fitting further comprises a waste inlet 31, a waste outlet 32 and an overflow fitting 50. The waste inlet is mounted towards the underside of the bowl 12, with or without a seal, e.g. by screwing through a hole in the centre of a strainer in the bottom of the bowl 12. The waste outlet 32 is connected to a drain pipe 90 or a waste trap. The overflow fitting 50 can be used for connecting a hose that is designated for transporting overflow from the bowl to the waste outlet fitting. The overflow fitting 50 is a second waste inlet of the waste outlet fitting 20.

Figures 5 to 8 depicts the sink arrangement 10 with the grating 60 in its lowered position and in a partially raised position respectively. The grating 60 may comprise a bend at its one end which ensures that the bars on the grating have a horizontal position when the grating 60 is in its lowered position.

Figures 9 to 12 shows a sink unit 11 being a possible embodiment of the present invention. The sink unit 11 comprises in one embodiment a bowl 12 and a waste outlet fitting 20. The sink unit can be mounted to a wall by the waste outlet fitting 20 and hinge arrangements 80 of the grating 60 functioning as the support for the sink unit. In a second embodiment the sink unit 11 comprises a bowl 12, a splashback 70 and a grating 60. This second embodiment may be achieved in that the combined splashback and grating unit 13 is firstly attached to a wall by attaching screws through the holes on the upper end of the splashback. Then the bowl 12, with or without the waste outlet fitting 20, is attached to the splashback 70 and the wall by attaching screws through the hinge arrangements 80. This sink unit 11 may be assembled and packed before storage, transport or delivery to end user/customer for the assembly of the whole sink arrangement 10.

This sink unit 11 may be assembled and packed before storage, transport or delivery to end user/customer for the end assembly together with the grating and splashback unit 13 to make up and install the whole sink arrangement 10.

Figures 13 to 15 depict a waste outlet fitting 20 according to one embodiment of the present invention. The waste outlet fitting comprises a waste receiving part 30 and a supporting member 40. The waste receiving part 30 is adapted for receiving waste that flows out of the sink and directs the waste through the waste receiving part and into the drain pipe 90. The supporting member 40 comprises a first supporting arm 41 and a second supporting arm 42 extending from the waste receiving part forming a wall mount being an integrated/integral part of the waste outlet fitting. The supporting arms 41, 42 have an essentially horizontal extension from the waste receiving part 30 with a slight increase in the vertical height of the supporting arms towards the end opposite the waste receiving part for increased stability and higher vertical force resistance. The height of the supporting arms is increased by letting the bottom edge of the arms expand away from the top edge, thereby letting the top edge remain essentially horizontal. The supporting member may also comprise ribs running along the internal or external surfaces of the supporting arms 41, 42. The waste outlet fitting 20 further comprises an overflow fitting 50 arranged between the supporting arms 41, 42 of the supporting member 40.

Figures 16 and 17 show a waste outlet fitting 20 according to another embodiment of the present invention. The waste outlet fitting comprises a waste receiving part 30 and a supporting member 40. The supporting member 40 comprises an angle plate, integrated with the waste receiving part 30, with a first end attached to the waste receiving part 30 and a second end with a vertical surface adapted for attaching to a wall. The waste outlet fitting 20 further comprises a supporting wall arranged essentially vertical below the angle plate, for increased stability and higher vertical force resistance. This supporting wall may be arranged essentially at the middle portion of the angle plate. The waste outlet fitting 20 further comprises an overflow fitting 50 arranged above the supporting member 40.

Figures 18 to 21 show a waste outlet fitting 20 according to another embodiment of the present invention. The waste outlet fitting comprises a waste receiving part 30 and a supporting member 40 comprising two supporting arms 41, 42 adapted for mounting the waste outlet fitting 20 to a wall. The supporting arms 41, 42 extend from the waste receiving part 30 firstly in an essentially horizontal direction until a bend downwards allows the supporting member to extend/transcend in direction sloping downwards. The sloping angle of the transcending supporting arms 41, 42 ranging between about or equal to 90° as measured from the horizontal plane and close to 0° as measured from the horizontal plane. The supporting arms 41, 42 may also be extending from the waste receiving part 30 in a sloping manner without a bend. By ensuring that the wall attaching end of the supporting member 40 is well below the waste receiving part 30 of the waste outlet fitting, the forces that occur from loading of the sink arrangement 10 can be received more efficiently. This also simplifies the mounting of the sink arrangement, making the screw holes more accessible. The supporting member may also comprise durability improving ribs running along the internal or external surfaces of the supporting arms 41, 42. The waste outlet fitting 20 may comprise an overflow fitting 50 arranged between the supporting arms 41, 42 of the supporting member 40.

Figures 22 to 23 depict a waste outlet fitting 20 according to a further embodiment of the present invention. The waste outlet fitting comprises a waste receiving part 30 and a supporting member 40 comprising two supporting arms 41, 42 adapted for mounting the waste outlet fitting 20 to a wall. The supporting arms 41, 42 extend from the waste receiving part 30 in an arced way sloping downwards. The arced supporting arms 41, 42 facilitate the mounting of the overflow hose to the overflow fitting 50. The arced supporting arms 41, 42 extending with a shape being bent or curved in a plane extending downwards in the direction of the arms from the waste outlet fitting 20 and the horizontal plane.

Furthermore, by ensuring that the wall attaching end of the supporting member 40 is well below the waste receiving part 30 of the waste outlet fitting, the forces that occur from loading of the sink arrangement 10 can be received and carried more efficiently. This also simplifies the mounting of the sink arrangement 10, making the screw holes more accessible. The supporting member 40 may also comprise support improving ribs running along the internal or external surfaces of the supporting arms 41, 42. The waste outlet fitting 20 further comprises an overflow fitting 50 arranged between the supporting arms 41, 42 of the supporting member 40.

Figures 24 to 25 depict a waste outlet fitting 20 according to a further embodiment of the present invention. The waste outlet fitting comprises a waste receiving part 30 and a supporting member 40 comprising two supporting arms 41, 42 connected to the waste receiving part by a projection of the supporting member 45. The supporting arms 41, 42 are branched off from the projection 45 and adapted for mounting the waste outlet fitting 20 to a wall. The projection 45 and arms 41, 42 extend horizontally or close to horizontally but may extend vertically or close to vertically or at any angle therebetween. For increased stability, the supporting arms 41, 42 are connected by a vertical plate at the wall mounting side. The supporting member 40 may also comprise ribs running along the internal or external surfaces of the supporting arms 41, 42. The waste outlet fitting 20 may comprise an overflow fitting 50 arranged between the branched off supporting arms 41, 42 of the supporting member 40. The sink arrangement 10 is mounted to a wall/surface by firstly attaching the grating and splashback unit 13 to the wall at a desired height by screwing through the upper set of holes in the splashback 70. Secondly the waste outlet fitting 20 is mounted to the underside of the bowl 12 by screwing through the strainer in the bottom of the bowl and, if required, connecting the overflow hose to the overflow fitting 50 on the waste outlet fitting and to the corresponding overflow fitting on the bowl 12. Thirdly, the sink unit 11 (bowl 12 and waste outlet fitting 20) can be mounted to the wall and the grating and splashback unit 13 by introducing/inserting an edge of the bowl (this bowl edge shown with dashed lines in Figs.l, 5, 9, and 12) behind the lower part of the splashback 70 and then attaching screws through the fastening pins 81 and the corresponding holes in the bowl 12. The fourth step is to attach the waste outlet fitting 20 to the wall by attaching screws through the holes in the supporting arms 41, 42. The last step is to connect the drain pipe 90 to the waste outlet 32.

However, as the sink unit 11 may comprise the bowl 12 and the waste outlet fitting 20 as a pre-assembled module being transported together and not separately, the second step of assembling the waste outlet fitting 20 to the bowl 12 above is omitted/void as this is already done at the production site.
