Definitions

  • the invention to which this application relates is to an improvement to a device which is herein referred to as a waste trap, which is for use with a drain hole of, for example, a sink or basin.
  • Waste trap assemblies are typically used for two purposes, a first purpose, when the same is in a first position, to close and seal a drain hole in a sink, bath or the like and a second purpose when in a second position, to collect debris which may be present in the liquid in the sink or bath and prevent that debris from passing into the drain, as the liquid drains from the sink or bath through the drain hole.
  • the waste trap conventionally comprises a body formed of metal or a metal alloy which is typically of a similar dimension to the drain hole and which has a trap, typically formed as a basket, with perforations therein which allow liquid to pass therethrough, but at least the larger significant items of debris, to be retained in the basket.
  • the trap is then, from time to time, removed from the drain hole by the user, typically once the liquid has drained from the sink.
  • the collected debris can then be carried in the trap to a location where the debris can be discarded safely, such as a waste bin.
  • the waste trap also typically includes a sealing member, typically on the underside of the basket, which is formed of a resilient substance such as, for example, rubber or rubber equivalent, and this sealing member is provided so as to provide a substantially watertight seal of the drain and therefore act as a plug when the trap is in the first position.
  • the trap typically includes a member along the central axis thereof, and which member acts as a guide for the movement of the trap between the first and second axial positions. In the first axial position, the trap is inserted further into the drain hole such that the sealing member engages the drain hole and causes a seal to be achieved therefore allowing liquid to be collected in the sink.
  • the waste trap In the second position, the waste trap is moved axially away from the drain hole, but still located therewith. This allows liquid to drain from the sink, through a gap around the periphery of the trap and through the apertures in the trap basket, and into the drain hole.
  • the gaps are of a size so as to prevent the larger items of debris passing into the drain hole and therefore this debris is retained in the trap basket.
  • Waste traps of this design are well known, and do work effectively. They can be unsightly but, due to their useful function, have largely remained in the same form for a long period of time.
  • the aim of the present invention is to provide an improved waste trap, which at least maintains the functional performance but preferably improves the same, and which also has an improved appearance when in use.
  • a waste trap assembly for use in conjunction with a drainhole in a sink, bath or similar item, said assembly having a waste collecting means and wherein said waste collecting means can be manipulated by a user between a debris collection configuration and a debris discarding configuration.
  • the waste collecting means or “basket” as it can often be called is provided in a debris collecting configuration while the waste trap is located in the drain hole in either first or second positions and can be moved to the debris discarding configuration when the assembly is removed from the drain hole such as at a location at which the debris held in the basket is to be discarded.
  • the user manipulation involves moving at least part of the side walls of the waste collecting means to allow debris to fall out of the waste collecting means and also increase a gap between the periphery of the waste collecting means and the underside of a cover axially mounted above the waste collecting means so as to more easily facilitate the removal of the debris.
  • the manipulation involves moving the side walls to move the same "over centre".
  • the waste collecting means is formed of a resilient material such that force is applied to the side walls to move the same from either configuration to an intermediate location whereupon continued application of force causes the resilience of the material to move the waste collecting means automatically to either of the collection or discarding configurations.
  • the shape of the waste collecting means in conjunction with the resilience of the material, encourages the waste collecting means to remain in either of the collection or discarding configurations without application of force or other support being required.
  • the ability for user manipulation of the waste collecting means between collection and discarding positions, means that the debris can be more easily discarded from the waste collecting means. This is particularly important when the waste trap assembly includes a cover mounted above the waste collecting means, as although the spacing between the cover and the waste collecting means is sufficient to allow debris to pass into the waste collecting means, it may not be sufficient so as to allow a user to insert their fingers or other utensils into the waste collecting means to remove the debris therefrom.
  • this problem is solved by the current invention by providing the waste collecting means to be manipulable between the debris collecting and debris discarding configurations so as to provide a greater size of gap between the cover and the waste collecting means when it is necessary to gain access to the same to remove debris therefrom.
  • a method of use of a waste trap assembly with respect to a drainhole comprising the steps of moving the assembly to a lowered position in the drainhole to substantially seal the same and allow liquid to collect in a sink or bath or similar item for use; and, when the use is complete, moving the waste trap assembly to a raised position in the drainhole to allow liquid to pass through the drainhole and waste debris to be collected in a waste collecting means of the assembly in a debris collecting configuration and wherein the assembly is removed from the drainhole and the waste collecting means manipulated by a user from the debris collection configuration to a debris discarding configuration to allow debris to be discarded from the waste trap assembly.
  • the waste collecting means is formed from a material which can be deformed by the user to move the same between the debris collection and debris discarding configurations.
  • the material is sufficiently resilient so as to remain in either of the debris collecting or debris discarding positions until user force is applied thereto.
  • the waste collecting means incorporates a sealing means formed as part thereof, said sealing means provided to allow the drain hole to be substantially sealed when the waste trap is in the first position.
  • the waste collecting means which is provided as part of the assembly, is provided with a rib portion extending around the periphery of the same.
  • the rib portion is of an increased thickness compared to the wall thickness of the remainder of the waste collecting means.
  • the rib portion is formed at the free edge of the collecting means.
  • the rib portion acts to allow a more controlled movement of the waste collecting means between the waste collecting configuration and the waste discarding configuration. This more controlled movement ensures that the movement is predictable and therefore prevents the risk of splashing or scattering of collected waste from the collecting means as the movement is being performed by the user.
  • the assembly incorporates sealing means which, when the assembly is in a closed position, act to seal the drain hole to substantially prevent the passage of water therethrough, said sealing means being formed integrally with at least one other component of the assembly.
  • the sealing means is formed integrally with the waste collecting means.
  • the assembly typically includes a cover member mounted coaxially with the waste collecting means and axially spaced therefrom.
  • the cover means is located such that when the assembly is in the lowered position in the drainhole the top surface of the cover member lies substantially flush with the surface of the sink or bath in which the drainhole is provided.
  • a waste trap assembly for a drain hole of a sink or bath or similar item, said waste trap including a waste collecting means for the collection of debris therein as liquid drains through the waste trap into the drain hole and wherein a cover member is provided, said cover member axially spaced from said waste collecting means.
  • the cover member is spaced from the waste collecting means to a sufficient extent such that as liquid drains through the drain hole, debris can pass through the space between the cover and waste collecting means and be collected by the waste collecting means thereby preventing the same from passing into the drain hole and also preventing the debris from clogging the area around the drain hole.
  • the upper surface of the cover member is shaped so as to encourage liquid and debris to move along the surface to the periphery of the cover and then into the waste collecting means.
  • the waste trap is axially movable with regard to the drain hole between a first, sealing position in which liquid is substantially prevented from entering the drain hole and a second position in which liquid can pass around and through apertures provided in the trap waste collecting means, to enter the drain hole.
  • the axial movement, and the extent of the same is provided such that when the trap is in the first position, the external face of the cover lies substantially flush with the face of the sink adjacent the drain hole.
  • the waste collecting means is hidden from view when the trap is in the first position, thereby improving the appearance of the waste trap and the sink.
  • the waste trap includes a sealing means, said sealing means acting when the waste trap is in the first position to seal the drain hole and therefore prevent liquid from leaving the sink.
  • FIG. 1 and 6 there is illustrated part of a kitchen sink 2 assembly which includes a drain hole 4 and in which there is positioned a waste trap assembly 6 in accordance with an embodiment of the invention.
  • the waste trap is shown in a first, closed position, in which the top surface 8 of a cover 10 of the waste trap lies substantially flush with or slightly below the surface 12 of the base of the sink.
  • the waste trap is effectively sealing the drain hole 4 in a sealed, closed, position so that liquid can be poured into the sink 15 and collected and retained in the sink for washing use.
  • FIG. 5 illustrates the waste trap components in more detail in accordance with one embodiment of the invention and it will be seen that the waste trap incorporates a central axis member 30. On that member, at spaced intervals, are provided the cover 6 and then spaced downwardly therefrom, the waste collecting means or basket 18 with the apertures 28 therein. Below that, there is formed a seal 32 and part of the mechanism 22 which allows the movement of the waste trap between the open and closed positions shown in Figures 1 and 2 .
  • the mechanism is the subject of separate patent protection and therefore is not described in detail here. However, in this example the simple pressing action on the cover is sufficient to move the waste trap between the first and second positions. However other movement mechanisms could be used without affecting the advantages of this invention.
  • the provision of the cover in addition to the waste collecting means basket, means that the waste trap assembly itself is more attractive in use as it provides, in the closed position, a substantially flush base surface and the drain hole and waste collecting means basket are therefore hidden from view.
  • the waste trap assembly 6 is located in a housing 34 which is mounted in the drain hole of the sink assembly.
  • the waste collecting means basket 18 can be used to advantage without the cover being provided and therefore the assembly could be provided in accordance with one embodiment of the invention without the cover.
  • a problem which is created by the provision of the cover 10 is that the gap 38 between the underside 36 of the cover and the peripheral lip of the basket 18 is such that it is difficult for a user to gain access to any debris which may be collected in the basket in order to be able to remove the same.
  • the basket was of a conventional type made of sheet metal which is formed as a fixed, rigid shape, then, in many instances, the waste trap basket 18 would not be usable as debris cannot be recovered therefrom.
  • this problem has been appreciated and dealt with in the following manner in the current invention.
  • the basket 18 is provided in a debris collection configuration in which the side walls 40 of the basket, depend upwardly leading to a peripheral lip 42.
  • the surface of the cover can be domed or otherwise shaped so as to encourage the liquid and any debris thereon to move to the peripheral edge of the cover and then move as indicated by arrows 24 downwardly towards the basket 18.
  • the waste trap assembly can be removed from the drainhole as indicated by arrow 41 in Figure 8 and then used to carry any debris in the basket until it is desired to discard the same.
  • the basket can be manipulated by the user to a configuration shown in Figures 4 and 9 .
  • the movement can be achieved as the basket is formed of a substantially resilient, flexible material such as nitrile rubber.
  • the hardness of the rubber is in the region of 50-70 shore hardness and provides sufficient rigidity of the basket so as to retain it in the required configuration but the same is still sufficiently flexible so as to be manipulable by the user between configurations.
  • the movement can be achieved by the user gripping the peripheral lip 42 and then moving the same as indicated by arrows 46 in Figure 8 .
  • the resilience of the material causes the basket to continue the movement automatically to the debris discarding configuration shown in Figures 4 and 9 .
  • the movement can be achieved in the opposite direction by the user gripping the peripheral lip 42.
  • the debris is no longer held in the basket when the waste trap is held upright and so the debris can fall into, for example, a bin.
  • the waste trap in use, in the sink, the waste trap can be moved between first and second closed and open positions accordingly.
  • the waste trap sealing member 32 which can be provided as an integral part of the basket, seals against the drain hole to effectively prevent liquid leaving the sink through the drain hole when the waste trap is in the first closed position.
  • the waste trap In order to drain the liquid from the sink, the waste trap can be moved to the second position shown in Figure 2 and water can then drain through the drain hole via apertures provided in the basket. The drain hole is exposed as the waste trap has been moved upwardly to raise the cover from the surface of the sink and bring the waste trap assembly 6 to the entry into the drain hole and remove the sealing member 32 from the drain hole.
  • the user may then wish to discard any debris which is held in the basket of the waste trap. To do this, they release and remove the waste trap from the drain hole and sink completely, and carry the same, with the basket still in the configuration shown in Figures 3 and 8 .
  • the user can grip the peripheral edges of the basket and move the same downwardly to the configuration shown in Figures 4 and 9 wherein debris can fall out of the basket 18.
  • the debris can be accessed relatively easily and the user need not try and place utensils or their fingers between the gap of the peripheral of the basket and the underside of the cover when it is in the normal configuration shown in Figure 3 .
  • a drain hole 102 in a sink 104 which allows the passage of water from the sink to the drainage means.
  • the waste trap assembly in this embodiment, comprises a top cover 108 mounted on a longitudinal shaft 110 around which is also disposed, at a spaced location from the cover, a waste collecting means 112 and, formed as part of thereof, sealing means 116 shown in more detail in Figures 11a-c .
  • the sealing means 116 are provided to locate on the drain hole, when the assembly is in the closed position of Figure 10b , in order to seal the drain hole and maintain the liquid in the sink.
  • the assembly is axially movable, either by manual movement or by an actuating means, so as to allow the assembly to be moved upwardly, to an open position as shown in Figure 10a , and downwardly to a closed lowered position as shown in Figure 10b .
  • the free end or edge 118 of the waste collecting means 112 is formed with a rib 120 of an increased wall thickness as compared to the wall thickness of the remainder of the waste collecting means.
  • the provision of the at least one rib improves the movement of the waste collecting means between the collecting position shown in figures 10a and 10b and a waste discarding position shown in broken lines in figure 10a , and between which positions the collecting means can be moved by manual manipulation typically by gripping the edges of the same.
  • the provision of the rib 120 allows a more controlled movement to be achieved between the configurations of collecting and discarding.
  • sealing means 116 is provided as an integral part of the waste collecting means 112, typically being formed as a common part and of a common material, thereby simplifying the manufacture and reducing the number of components required for the assembly.
  • a waste trap assembly which allows the waste collecting means to be effective in preventing debris from passing into the drain and which still allows the debris to be effectively removed therefrom, even when a cover is provided and at the same time providing an assembly which has improved appearance and effect.
