Definitions

  • This invention concerns improvements in or relating to ablutionary appliances. More especially, the invention relates to the design of actuators utilised with ablutionary appliances, in particular, but not exclusively mixing valves.
  • ablutionary controls In ablutionary appliances, it is desirable for ablutionary controls to give the user a feel of quality.
  • One way to achieve this is to increase the 'weight' of the actuator in order that it should give the impression of quality and robust manufacture. This is often achieved by giving the actuator an increased resistance to actuation. It is desirable that the actuator runs smoothly, but nonetheless gives a certain resistance to actuation. For this reason actuators used in ablutionary systems are often provided with protrusions such as ribs, offering the user greater purchase, especially where it might be expected that water, soap and/or other chemicals might reduce the ability of the user to gain purchase on the actuator.
  • the controls are visible and accessible at all times.
  • the present invention seeks to provide ablutionary appliances with an alternative control that may provide the designer with more options potentially allowing improved aesthetics.
  • an ablutionary appliance having a manually operable actuator for controlling operation of the appliance, wherein the actuator is extendible from a retracted, inoperative position to an extended, operative position.
  • the actuator is preferably substantially flush with an adjacent or surrounding surface in the retracted position and extends away from the surface for actuation by the user in the extended position.
  • the surface may be provided by a housing of the ablutionary appliance.
  • the housing may be in the form of a shelf.
  • the shelf may have an upper surface and a front surface and the actuator is preferably located in the front surface.
  • the housing may contain an ablutionary fitting such as a mixing valve operable by the actuator.
  • the mixing valve may be non-thermostatic or thermostatic. Other configurations, applications and uses of the housing are envisaged.
  • the housing may provide a substantially flat fascia surface such that when in the retracted position, the actuator preferably provides a continuation of the substantially flat fascia surface and, when in the extended position, the actuator extends away from the fascia surface for actuation by the user.
  • Such an arrangement may be advantageous in that, when the actuator is in the retracted position, the substantially flat fascia, including exposed portions of the actuator, may be easier to clean. Additionally the substantially flat fascia including the actuator may provide designers with new aesthetic options and may give the ablutionary appliance a more elegant appearance.
  • the actuator is held in the retracted position by a retainer mechanism and, when released, is biased to the extended position. In this way, the actuator is automatically moved to the extended position without the user having to pull the actuator out of the fascia. This may give the impression that the actuator is elegant and non-cumbersome.
  • the actuator can be manually returned to the retracted position whereupon the actuator is retained in the retracted position by the retainer mechanism.
  • the retainer mechanism may be released by pushing the actuator against the biasing of a spring when in the retracted position allowing the actuator to move to the extended position under the biasing of the spring.
  • the retainer mechanism is preferably re-engaged when the actuator is returned to the retracted position so as to retain the actuator in the retracted position.
  • the extension and retraction of the actuator is guided by a track which co-operates with the actuator and retains the actuator in the retracted position until the actuator is released whereupon the actuator is guided to the extended position.
  • the track also guides the actuator for return movement to the retracted position to re-engage the retainer mechanism.
  • the actuator When in the extended position, the actuator is preferably rotatable about an axis perpendicular to the adjacent or surrounding surface. This may be an intuitive way for a user to adjust the actuator, and may mean that a relatively simple suitable mechanical connection can be made to the appliance, for example a thermostatic mixing valve or the like.
  • rotation of the actuator is achieved by gripping an exterior wall of the actuator that becomes accessible as a result of the actuator being in the extended position.
  • the actuator may be configured to help the user gain grip on the actuator to aid operation. This may be particularly advantageous in view of the fact that water, soap and/or other chemicals present may serve to reduce grip. This may also allow the actuator to be provided with a greater resistance to actuation, thus potentially increasing the apparent quality and robustness of the actuator.
  • grip may be enhanced by the shape of the actuator and may include integral formations such as ribs.
  • the actuator is provided with at least one formation movable between a retracted, stored position within the actuator when the actuator is in the retracted position and an extended, exposed position projecting from the actuator when the actuator is in the extended position.
  • This may be advantageous in that the or each formation may be extended when required to aid gripping the actuator and retracted when it is no longer required. In this way the aesthetic of the actuator may be improved.
  • This may also be advantageous in that there is no need to accommodate the formation in the adjacent or surrounding surface when the actuator is in the retracted position.
  • the at least one formation is extended outward from a wall of the actuator, preferably radially, as the actuator is moved from the retracted position to the extended position in which the wall is accessible.
  • the at least one formation may be movable between the retracted position and the extended position in response to movement of the actuator between the retracted position and the extended position.
  • a mechanism may be provided that is responsive to movement of the actuator between the retracted position and the extended position to move the at least one formation between the retracted position and the extended position.
  • the at least one formation may be mounted for pivotal movement between the retracted position and the extended position and the mechanism is preferably operable to pivot the at least formation in response to movement of the actuator between the retracted position and the extended position.
  • the mechanism may comprise a pin and slot.
  • the mechanism may comprise a rack and pinion.
  • the at least one formation may be biased towards the retracted position and the mechanism is preferably operable to move the at least one formation to the extended position in response to movement of the actuator from the retracted position to the extended position.
  • the mechanism may be operable to allow the at least one formation to return to the retracted position under the biasing in response to movement of the actuator from the extended position to the retracted position.
  • the mechanism may comprise a rotatable cam
  • the at least one formation may be biased towards the extended position and is preferably retained in the retracted position when the actuator in the retracted position by a blocking member that prevents the at least one formation moving to the extended position.
  • the blocking member preferably releases the at least one formation in response to movement of the actuator from the retracted position to the extended position allowing the at least one formation to move to the extended position under the biasing.
  • the at least one formation is preferably co-operable with the blocking member to return to the retracted position against the biasing in response to movement of the actuator from the extended position to the retracted position.
  • the blocking member may comprise a wall that surrounds the actuator or that part of the actuator in which the at least one formation is received in the retracted position of the actuator.
  • the actuator may be used to control the temperature and/or flow of water. Separate actuators may be provided for temperature and flow control. Alternatively, a single actuator may control both functions.
  • an actuator for operating a device, the actuator being movable from a first position to a second position and having at least one formation movable from a position substantially within the actuator to a position projecting from the actuator.
  • the actuator is biased towards the second position and is retained in the first position until released whereupon the actuator moves to the second position under the biasing, for example the actuator may be biased by a spring.
  • the actuator may be capable of actuation to operate the device in the second position. Operation of the device may be prevented when the actuator is in the first position.
  • the at least one formation is movable to project from the actuator in response to movement of the actuator to the second position.
  • the at least one formation may assist actuation of the actuator.
  • the at least one formation may help a user grip the actuator.
  • the actuator and formation may comprise any of the features of the preceding aspect of the invention.

  • a casing 100 forming part of an ablutionary appliance (not shown) is provided.
  • the casing 100 contains a thermostatic mixing valve (not shown) to which is supplied hot and cold water for mixing and supply of temperature controlled water to an outlet, for example a shower.
  • the casing 100 is in the form of a hollow shelf that can be mounted on a wall (not shown) to conceal the mixing valve and the fluid connections to the valve.

  • Actuator 102 has a substantially circular cross- section and its outer end surface 104 is substantially flat.
  • the actuator 102 is coupled via a mechanical connection with the thermostatic mixing valve to alter the temperature of the water delivered to the outlet in accordance with user selection.
  • the actuator 102 may be used to vary the flow rate of water delivered to the outlet via a similar mechanical connection.
  • the actuator 102 may control temperature and flow rate of water delivered to the outlet. It is also envisaged that two actuators 102 might be provided, one to control the temperature and the other to control the flow rate of the water delivered. .
  • the actuator 102 is shown in a retracted, inoperative position. In this position the actuator 102 is contained within the casing 100 and the outer end surface 104 of the actuator 102 is substantially flush with the fascia 106 such that the actuator 102 cannot be used to control the thermostatic mixing valve.
  • the actuator 102 is shown in an extended, operative position. Extension of the actuator 102 gives access to an exterior sidewall 108 of the actuator 102 such that the actuator 102 can be used to control the thermostatic mixing valve.
  • a blade formation 110 projecting generally radially from the exterior sidewall 108 in an extended, exposed position. The exposed part of the blade formation is approximately triangular in shape although other shapes and configurations are possible. The exposed part of the blade formation 110 extends substantially perpendicular to the exterior sidewall 108 of the actuator 102. Part of the formation 110 also extends into the body of the actuator 102 through a hole 112 in the exterior sidewall 108.

  • the formation 110 can be seen in the extended, exposed position with the exposed part extending perpendicular to the exterior sidewall 108.
  • a sleeve 114 can be seen, which connects the actuator 102 to the thermostatic mixing valve (not shown) .

  • the actuator 102 is shown in its retracted position.
  • the sleeve 114 is largely contained within the body of the actuator 102.
  • a spring 116 seated in a pocket 118 of the sleeve 114 acts between the sleeve 114 and the outer end wall 104 of the actuator 102 so as to bias the actuator 102 towards its extended position.
  • the actuator 102 is held in the retracted position preventing it from moving to the extended position by engagement of a pin (not shown) forming part of the actuator 102 with a part of a track (not shown) on the sleeve 114.
  • the formation 110 is shown in the retracted position.
  • the formation 110 is guided by a protrusion 120 on its proximal end that cooperates with a guide 122.

  • the actuator 102 can be rotated to control the thermostatic mixing valve (not shown) .
  • the user pushes the top surface 104 of the actuator 102 inwards releasing the pin allowing the actuator 102 to move to the extended position under the biasing of the spring 116 while guided by engagement of the pin in the track. In this way the actuator 102 automatically 'pops-out' of the casing 100 when released. Simultaneously through the action of the protrusion 120, guide 122 and pivot 124, the formation 110 moves out of the actuator 102 into the extended position. The user may now rotate the actuator 102 about axis A, using the formation 110 for better grip.
  • Rotation of the actuator 102 causes rotation of the sleeve 114, which in turn adjusts the thermostatic mixing valve in order to change the temperature of the water delivered.
  • the actuator 102 may be pushed back into the casing 100 against the biasing of the spring 116 while guided by engagement of the pin in the track until the pin re-engages a portion of the track to retain the actuator 102 in the retracted position against the biasing of the spring 116.
  • the formation 110 is simultaneously moved to the stored position inside the body of the actuator 102 through the action of the protrusion 120, guide 122 and pivot 124.
  • the end surface 104 of the actuator 102 is substantially flush with the fascia 106, making the fascia 106 easy to clean and giving the casing 100 a pleasing aesthetic.
  • the actuator has a single blade formation as described but it will be understood that two or more blade formations may be provided and these may arranged with a uniform or non-uniform spacing.
  • Figures 7 to 24 show a number of actuators that can be used in place of the actuator 102 shown in Figures 1 to 6 for controlling operation of a mixing valve or any other article employing a rotatable actuator.
  • Each of the actuators shown in Figures 7 to 24 preferably has a substantially circular cross-section and a substantially flat outer end surface and is movable between a retracted or closed position in which the outer end surface is preferably substantially flush with the surrounding surface of the housing for the mixing valve and an extended or open position in which the actuator projects from the housing for rotation by the user to control operation of the mixing valve.

It will be understood that the invention is not limited to these embodiments and that the mechanisms described herein may be modified or altered without departing from the scope of the invention. Thus, in the above-described embodiments, we may employ more than one guide track and slot with a follower therebetween to guide the actuator between extended and retracted positions.
  • the grip enhancing formation (s) may have the form of blades as described or any other suitable form.
  • the track may extend on one side only to guide the blade out as the actuator extends as already outlined and, as the actuator retracts, a spring or other suitable means pushes the blade back into to place rather than the other side of the track guiding the blade back in. While the actuator has been described for operating an ablutionary appliance, it may have application for operating other appliances.

Abstract

L'invention concerne un appareil sanitaire, tel qu'un mitigeur, comprenant un actionneur (102) faisant saillie à partir d'une face (106) d'un boîtier lorsqu'il est en position active, l'actionneur (102) pouvant alors être tourné manuellement en vue de la commande du mitigeur. L'actionneur peut être maintenu dans une position inactive dans le boîtier, une surface avant (104) de l'actionneur (102) étant alors sensiblement à fleur de la face (106), et se déplace dans la position active lors de sa libération. Une ailette (110) est montée pivotante dans l'actionneur (102) et s'étend à partir de la paroi latérale (108) de l'actionneur (102) dans la position active. Cette ailette (110) améliore la préhension de l'actionneur (102) par l'utilisateur dans la position active. Ladite ailette (110) est rentrée dans l'actionneur (102) lorsque ce dernier revient en position inactive et sort lorsque l'actionneur entre en position active.
