Definitions

  • the present invention relates to the fitting of a tap or faucet to a support surface such as a sink, basin, bath, kitchen worktop or the like.
  • the tap has a body and a threaded tail piece, typically in the form of a tail pipe that extends from the body.
  • the tail pipe is inserted through a hole in the support surface so that the free end of the tail pipe projects beyond an inner, usually lower, face of the support surface with the body resting on an outer, usually upper, face of the support surface.
  • a nut is screwed onto the tail pipe so as to engage the inner face of the support surface and is tightened so that the support surface is clamped between the nut and the body of the tap.
  • a flexible washer may be provided between the body of the tap and the outer face of the support surface and the nut may be plastic or a further flexible washer may be provided between the nut and the inner face of the support surface to reduce the risk of the support surface cracking, particularly where the support surface is made of a ceramic material, and to improve the grip between the tap and the support surface.
  • the water supply is then connected to the tail pipe using a suitable fitting or connection.
  • a tap adapted for mounting on a support surface
  • the tap comprising: a body; a threaded tail piece extending from the body; a locking nut and a back nut both threaded on the tail piece, the locking nut being provided closer to the body than the back nut; and an anchor means provided around the tail piece between said locking nut and said back nut; characterised in that said locking nut does not fit through a hole provided in said support surface for mounting the tap whereas said back nut and said uncompressed anchor means are adapted to fit through said hole but wherein said anchor means is deformable when compressed between said locking nut and said back nut such that it engages the hole and/or the support surface around the hole to secure the tap in position.
  • the tail piece provided with locking nut, anchor means and back nut may simply be dropped into a hole provided in a support surface and then secured in position by tightening the locking nut.
  • the compression of the anchor means causes it to deform and engage with the hole or the support surface around the hole and thus holds the tap in position.
  • the anchor means may comprise generally a tubular form.
  • the anchor means may be generally deformable outwardly when compressed by the locking nut and the back nut at each end. Accordingly, the anchor means will thus engage the sides of the hole through the surface and help to secure the tap in position.
  • the anchor means may have an inwardly bevelled lower edge.
  • the back nut may be provided with correspondingly sloped upper edge. This helps to urge the anchor means to deform outwardly.
  • the anchor means may be provided with one or more longitudinal slits. These slits may aid the outward deformation of the anchor means under compression.
  • the slits may run upwardly from the lower edge of the anchor means, downwardly from the upper edge of the anchor means, or may not extend to either edge.
  • the anchor means has an inwardly bevelled lower edge, preferably the slits run upwardly from the lower edge of the anchor means. In this manner the outward deformation is optimised.
  • the slits may preferably run downward from an upper edge of the anchor means.
  • the outward deformation of the anchor means will result in its upper edges engaging the underside of the surface around said hole and thus retaining the tap in position.
  • This can be achieved by putting an anchor means as described above onto the tailpiece in the opposite orientation.
  • the back nut may also be threaded onto the tailpiece in the opposite orientation such that its flat surface engages with the flat edge of the anchor means. This helps to maintain the stability of this arrangement.
  • the anchor means may be formed from any suitable deformable material.
  • the suitable material may be a composite or a plastic.
  • the anchor means may be provided with one or more projecting teeth on its outer surface.
  • the teeth may be of a wedge like form having an upper edge projecting substantially orthogonally to said outer surface and a lower edge at an acute angle to the outer surface. In such a manner, the upper edge of the tooth may engage with an underside of the surface upon which the tap is mounted, when the anchor means is compressed. Furthermore, this shape of wedge enables the anchor means to be readily passed through the hole in the fitting process.
  • two or more anchor means may be provided between the locking nut and the back nut.
  • a washer may be provided between said anchor means.
  • the anchor means has an inwardly bevelled lower edge
  • the washer has a correspondingly sloped upper edge.
  • Two or more anchor means may be provided where the surface is relatively thick, such that both anchor means are involved in engaging the hole or the under surface around the hole. This provides additional grip and thus a more secure mounting of the tap.
  • a washer may be provided between the lower surface of the locking nut and the upperside of the mounting surface. This can improve the grip between the locking nut and the support surface.
  • a cover may be provided with means for enabling it to be secured in position over the locking nut.
  • the cover may be adapted to snap fit or clip over the locking nut.
  • the locking nut and the cover may be provided with co-operating features for maintaining them in a desired relative position.
  • the cover may be provided with an internal thread and the locking nut may be provided with a corresponding external thread.
  • the external thread may be provided on an edge of a projecting flange.
  • the thread may be provided upon adapted corner portions of the locking nut. The provision of the corresponding threads enables a cover having a suitable internal thread to be secured over the locking nut.
  • the locking nut in particular or the tap in general may be adapted in any other suitable manner such that the cover is maintained in position over the locking nut.
  • the cover may have a decorative outer surface.
  • the cover may be adapted to be tightened by hand rather than by use of a tool.
  • the cover may be positioned around the tail piece before said locking nut is threaded on to said tail piece.
  • the tail piece may be formed integrally with the body or may be detachably connected to the body.
  • a detachable connection may be a press fit connection, a screw connection or any other suitable form of connection.
  • One example of another suitable form of connection would be maintaining the tap body and the tail piece in connection by the use of one or more grub screws which grip onto the tail piece.
  • the cover may also be adapted to grip onto the grub screws and thus help to maintain the cover and or the tap body in position. In embodiments wherein the tail piece is detachably connected to the body, the cover may act to help secure the tap in position relative to the tail piece.
  • the tail piece may comprise a pipe having an internal bore through which water can pass and a threaded outer surface. Such a tail piece is suitable for an embodiment wherein the tap controls the flow of water from a single water supply.
  • the tail piece may comprise a substantially cylindrical block having a threaded outer surface and two or more internal bores running substantially parallel to the axis of the block. Such a tail piece is suitable for an embodiment wherein there is more than one water supply to the tap.
  • the tail piece may be provided with suitable means to facilitate connection to a water supply pipe.
  • the connection may be facilitated by a press fit connection, a screw connection, brazing, soldering or bonding using suitable adhesive or any other suitable form of connection.
  • each individual internal bore may be provided with means for connection to a water supply.
  • the individual inner bores may be provided for connection to hot and cold water supplies or to hot, cold and filtered water supplies.
  • the body may provide separate internal pathways for the water supplied through each bore.
  • the pathways may be provided with separately operable valve means to control the flow through each pathway independently.
  • Each pathway may finish in a separate outlet nozzle or the pathways may all end at a common outlet nozzle.
  • the support surface may comprise, but is not limited to, any of: a sink, a basin, a bath or a worktop in which a sink, basin, bath or the like is mounted
  • a method of mounting a tap to a support surface in which the tap has a threaded tail piece that is inserted through a hole in the support surface; the method comprising: threading a locking nut and a back nut on the tail piece, an anchor means being provided around the tail piece between said back nut and said locking nut wherein said anchor means and said back nut are adapted to fit through the hole and said locking nut does not fit through the hole; passing the tail piece, back nut and anchor means through the hole; and tightening the locking nut such that said anchor means is compressed between said locking nut and said back nut wherein anchor means is deformable under compression such that it engages the hole and/or the support surface around the hole to secure the tap in position.
  • the method of the second aspect of the present invention may incorporate any or all features described in relation to the first aspect of the present invention as desired or as appropriate.
  • a tap 100 comprising a body 110 and a threaded tail piece.
  • the tail piece comprises a tail pipe 120 having an internal bore through which water may pass and a thread provided on the outer surface.
  • the body comprises a central body portion 111, a spout 112, handle 113, a lever 114 operable to turn said handle 113 and an indicator plate 115.
  • the indicator plate may be replaced by a suitable etching pattern or similar on handle 113.
  • a mechanism 116 (see figure 3) operable to open or close a passage within the body 110 such that water may pass from the tail pipe 120 to the spout 112.
  • the body 110 is also provided with a decorative cover 117.
  • the tail pipe 120 this is provided with a threaded outer surface 121.
  • a locking nut 122 Upon the tail pipe 120 are provided a locking nut 122, a locking washer 128, a pair of anchor means 123, a washer 124 provided between said anchor means 123, and a back nut 126. Both the locking nut 122 and the back nut 126 have threaded bores corresponding to the threaded outer surface 121 of the tail pipe 120.
  • the tap 100 is adapted to be mounted on a supporting surface (not shown).
  • the supporting surface might be a sink surround or a worktop.
  • a hole (not shown) is provided in the surface for the tail pipe 120 to pass through.
  • the locking nut 122 is screwed on to the tail pipe 121. Following locking nut 122, locking washer 128 and, one or both anchor means 123 is placed around the tail pipe 120. If both anchor means 123 are provided, the washer 124 is placed between them. Lastly, the back nut 126 is threaded on to the tail pipe 120. Before fitting the tap to a surface, the back nut 126, is threaded towards the locking nut 122 such that the anchor means 123 are held tightly therebetween.
  • the tail pipe 120 is passed through a hole provided in the surface.
  • the hole is of a size that the back nut 126 and anchor means 123 can pass through the hole but the locking nut 122 and locking washer 128 are unable to pass through the hole.
  • a spanner or other suitable tool is used to rotate the locking nut 122 such that it is driven towards the back nut 126. This causes the anchor means 123 to become compressed and deform outwardly. Accordingly, they engage with the edges of the hole and secure the tap 100 in position.
  • the locking washer 128 helps maintain a secure grip between the locking nut 122 and the surface.
  • the anchor means 123 are typically formed from a suitable material. Examples of suitable materials would include composites or plastics such as noryl or nylon. To assist the anchor means 123 in deforming outwardly, their lower edges 123a are inwardly bevelled. Similarly, the upper edges of the washer 124a and the back nut 126a have corresponding slopes. Furthermore, slits 123b are provided in the anchor means 123, to further assist in the outward deformation.
  • one or more of the anchor means 123 may be provided in the opposite orientation, such that when compressed the slits allow the bevelled edges 123a to splay against the underside of the surface around the hole and secure the tap in position.
  • This is illustrated in the alternative arrangement of figures 4a, 4b and 5.
  • the back nut 126 may be screwed onto the tail pipe 120 in the opposite orientation, such that its flat surface (normally the undersurface) is compressed against the flat edge (normally the upper edge) of the anchor means 123.
  • the anchor means 123 may further be provided with outwardly projecting wedge portions 123c.
  • the wedge portions 123c have a sloped under surface and a substantially outstanding upper surface, which eases the task of passing the anchor means 123 through the hole.
  • the wedge portions 123c also provide the anchor means 123 with additional purchase on the sides of the hole when deformed.
  • a further benefit is that should one of the anchor means 123 project below the under side of the support surface, when compressed, the upper surface of the wedge portion 123c may engage with the under side of the support surface, thus further securing the tap 100 in place.
  • the surface is relatively thin, such as a metal sink surround
  • only a single anchor means 123 may be used and the engagement between the upper surface of the wedge projections 123c and the underside of the metal sink surround may provide the primary security for the tap 100.
  • two (or more) anchor means 123 may be provided and the primary security for the tap 100 may be provided by the engagement between the anchor means 123 and the sides of the hole provided.
  • the locking nut 122 is provided with an external thread to correspond with an internal thread provided on the cover 117.
  • the external thread is provided by threaded corners 122a.
  • the cover 117 can thus be screwed down over the locking nut 122 such that its decorative outer surface lies substantially flush with the surface.
  • An alternative to providing a locking nut 122 with threaded corners 122a is shown in figure 10.
  • a locking nut 122 is provided with a projecting flange 122b around its lower rim.
  • the projecting flange 122b has a thread 122c provided on its external edge corresponding to the internal thread of the cover 117.
  • the cover 117 may alternatively be secured by the use of other means such as clips or similar.
  • the cover 117 is also provided with a pair of O-rings 118 and 119 to provide a watertight seal between the cover 117 and the supporting surface and between the cover 117 and the body 110.
  • the end 127 of the tail pipe 120 is adapted to connect to a water supply (not shown). Typically, this would be achieved by way of a push fit or screw fit connection (not shown) or by brazing, soldering or bonding using suitable adhesive.
  • a single water supply is controlled by the tap 100. It is of course possible that in alternative embodiments, two or more water supplies are desired to be controlled by a single tap unit.
  • a tap 200 operable to receive and control two separate water supplies is shown.
  • the tap comprises a body 210 and a threaded tail piece 220.
  • the tail piece 220 comprises a cylindrical block provided with a pair of internal bores 220a, 220b and a threaded outer surface 221.
  • the bores 220a, 220b are adapted to receive water from separate supplies and direct said water into a pair of separate internal passageways (not shown) with the body 210.
  • each passageway is controlled by a dedicated valve 213.
  • the valves 213 are operated by turning handle means 214.
  • An indicator plate 215 can be provided on each handle 214 to indicate to a user the particular water supply controlled by the valve 213.
  • water can pass along shaft 211 and into spout 212 from where it is output at an outlet nozzle 212a.
  • the shaft 211 and the spout 212 can be adapted to carry water from each supply along separate internal passageways or along a common internal passage way as required or desired.
  • connection means 231a, 231b may be push fit means, screw fit means (as shown in figures 6-9) or any other suitable means.
  • the connection means 231 a, 231 b may each be provided with an o-ring (not shown) to facilitate the completion of a watertight seal. Alternatively, the connection may be achieved by means of brazing, soldering or bonding using suitable adhesive.
  • each connection means 231a, 231b comprises a screw thread 232 corresponding to a thread provided on the interior of bores 220a and 220b; a hexagonal section 233 for facilitating the use of a spanner to screw the connection means 231 a, 231 b into the respective bores 220a, 220b; and connector 234 for connecting the flexible hoses 230 to the connection means 231a, 231b.
  • One of the connection means 231b is additionally provided with a spacer pipe 236 between the thread 232 and the hexagonal section 233. This provides some vertical separation between the hexagonal sections 233 of each connection means 231 a, 231 b and thus facilitates the use of a spanner to tighten the connection. This enables the supply pipes 230 to be readily connected to a pair of closely spaced bores 220a, 220b.
