  • FIG. 14 to 17 there is shown an example of an alternative back plate 101 for use in a control suitable for an ablutionary setting.
  • the embodiment described in relation to Figures 14 to 17 is the same as discussed above, unless explicitly stated otherwise.
  • the back plate 101 is substantially the same as the back plate 1 of Figures 1 to 13 and comprises a rectangular base 102 having a planar front surface 103 and a cylindrical side wall 104 extending axially outward from the front surface of the base 102.
  • the sidewall 104 is spaced away from the edges of the base 102.
  • the side wall 104 defines a circular perimeter, and defines a volume within it.
  • the water connection pipes 106 are configured to convey a flow of fluid from hot and cold water supplies.
  • the back plate 101 comprises a first actuator 110 disposed within the perimeter of the side wall 104.
  • the first actuator comprises a first portion 112 and a second portion 114.
  • the first portion 112 and second portion 114 are arranged to allow a threaded connection.
  • the first portion 112 comprises a collar defining threaded hole extending along a longitudinal axis, parallel to the axial direction of the sidewall 104.
  • the first portion 112 comprises a first surface 116
  • the second portion 114 comprises a second surface 118.
  • the first surface 116 comprises a planar surface disposed at an end of the first portion 112.
  • the second surface 118 comprises a substantially planar surface disposed at an end of the second portion 112.
  • the second surface 118 is disposed at an opposing end of the actuator 110 to the first surface 116.
  • the threaded hole does not extend through the second surface 118 of the first portion 112.
  • the overall length of the actuator is limited by the length of the second member 114.
  • the overall length of the actuator 110 is the length of the first member 112 projecting from the end of the second member 114, in addition to the length of the second member 114.
  • a second actuator 110a and a third actuator 110b comprise similar configurations to the first actuator 110 and are arranged spaced apart.
  • the base 102 comprises a plurality of sleeves 119, each sleeve 119 being configured to receive at least a portion of an actuator 110.
  • Each sleeve 119 is configured such that when an actuator 110 is received into the sleeve 119, the first portion 112 is prevented from rotating.
  • a thermostatic mixer cartridge 124 is disposed centrally upon the back plate 1.
  • the thermostatic mixer cartridge 124 comprises a plurality of inlets and outlets (not shown), each open and closed by one or more valves (not shown).
  • the thermostatic mixer cartridge 124 is configured to mix flows of water supplied from one or more water connection pipes 106, and convey a mixed supply of water to one or more other water connection pipes 106.
  • the actuators 110, 110a, 110b are operably connected to the valves to open and close the inlets/outlets. Movement of the actuators 110, 110a, 110b along the axial direction operates the valves.
  • the method of installing a control suitable for use in an ablutionary setting comprises a step of affixing the back plate 101 to a surface as shown in Figure 15 .
  • the surface may comprise a wall and the side wall 4 is arranged to protrude through an aperture disposed upon the wall, and as such the base 102 is not visible in Figure 15 .
  • the wall may have tiles 132 affixed to a front surface.
  • the distance between the base 102 and the most forward surface of the surrounding tiles 132 may vary significantly between installations.
  • the method may comprise a step of trimming or cutting at least a portion of the sidewall 104 to adjust the length the sidewall 104 extends form the back plate 101. This step is optional and may be omitted.
  • Figure 15 shows a back plate 101 with an intermediate plate 140 connected.
  • the intermediate plate 140 forms a connection to the side wall 104 of the back plate 101.
  • the intermediate plate 140 is configured to contact the tiles 132, and as such extends a known distance away from the tiles 132.
  • the intermediate plate 140 forms a connection with the side wall 104 by receiving a portion of the side wall into a rim portion 141.
  • the rim portion 141 is configured such that a depth of side wall 104 can be received up to a pre-determined maximum depth. Any portion of side wall 104 up to the maximum depth will not affect the relative position between the intermediate plate at the surrounding tiles 132. As such, inaccuracies when trimming the side wall 104 will not affect further installation steps.
  • Different intermediate plates 140 may be used in different installations configured to receive different maximum depths of side wall 104.
  • the intermediate plate 140 comprises a plurality of apertures through which actuators 110, 110a, 110b are arranged to at least partially extend.
  • the intermediate plate comprises a planar surface 142 in which the apertures are disposed.
  • a tab 143 is arranged to extend from the planar surface 142 and across at least a portion of each aperture. Each tab 143 is disposed in substantially the same plane as the planar surface 142.
  • Each tab 143 is arranged such that axial movement of the actuator 110, 110a, 110b is limited. As such, each tab 143 acts as a guide for extending the actuator 110, 110a, 110b to the correct length.
  • Rotation of the second portion 114 causes axial movement of the second surface 118 relative to the first surface 116.
  • the threaded connection between the first portion 112 and the second portion 114 allows for precise lengthening or shortening of the distance between the first surface 116 and the second surface 118.
  • the tab 143 provides a limiting means for adjusting the actuator 110 such that the second surface 118 is at the desired distance from the first surface 116.
  • the second portion 114 is operable to be rotated by hand or by using a separate detachable tool as discussed above, until the second surface 118 contacts the tab 143.
  • a fixing member can be connected to the intermediate plate 140.
  • the fixing member is arranged substantially similarly to the fixing member 28 as shown in Figure 11 . At least a portion of the top portion 117 is received by the fixing member.
  • the cooperating surfaces of the fixing member and the top portion 117 are arranged such that the top portion 117 is prevented from rotating. As such, the distance between the first surface 116 and the second surface 118 becomes fixed.
  • Figure 16 and 17 show a sectional view of a portion of the back plate 101.
  • the actuator 110 is positioned within the back plate 101, the intermediate plate 140 has been connected to the back plate 011 and the fixing member has been connected to the intermediate plate 140.
  • the actuator 10 has been received by the sleeve 119 and as such the first portion 112 is prevented from rotating.
  • the second surface 116 is arranged to contact a lever arm 138 of a control lever 136 of the valve.
  • a threaded shaft 115 of the second portion 114 is shown connected to the first portion 112.
  • Figure 16 shows the lever arm 138 raised such that the valve is in a closed configuration.
  • Figure 17 shows the lever arm lowered such that the valve is in an open configuration.
  • control lever 136 is arranged to extend from the valve and is arranged to rotate about an axis perpendicular to the axial direction of the actuator 110. In some embodiments, control lever 136 is operable to adjust valve from a closed configuration to an open configuration, or vice versa.
  • the first surface 116 contacts the control lever 136 such that movement of the first surface 116 in a first axial direction urges the lever arm 138 in the first direction.
  • a downward force on the second portion 114 of the actuator 110 causes the actuator 110 to move downward in the axial direction. This causes the first surface 116 to be urged downwards, and as such the lever arm 138 moves downwards to rotate the control lever 136.
  • control lever 136 may be operably connected to any suitable type of valve.
