Definitions

  • the present invention will be explained mainly with reference to its application to water taps, and in particular (although not necessarily exclusively) progressive mixer taps. However, application of the invention may also be possible to handles, knobs and the like used to operate or control devices other than water taps.
  • a water tap is a device by which the flow of liquid from a pipe or container (e.g. the flow of water from a tap spout, or from a bath spout, or from a showerhead, or the like) can be controlled.
  • Simple taps used for controlling the flow of water from tap spouts, bath spouts, showerheads, etc, are ubiquitous and do not require explanation.
  • a mixer tap is a type of water tap which is connected to, and which receives water from, both a hot water supply/pipe and a cold water supply/pipe.
  • Many mixer taps operate in such a way that, not only can the user control the rate of flow of the water exiting the water spout or other water outlet (i.e.
  • the user can also, with one and the same tap, control the relative proportions of hot and cold water that mix prior to exiting the spout or outlet, such that the temperature of the water flowing from the spout/outlet can also be controllably varied (anywhere between the temperature of the cold water supply (“full cold”) and that of the hot water supply (“full hot”)).
  • the mixer tap has a lever-type handle 1.
  • the user can control the rate of flow of water exiting the spout (the water outlet is a spout in this case) by lifting the lever, or more technically by pivoting the lever in a plane that includes the axis A of the tap, as indicated by arrow F in Fig 1.
  • lever-type mixer taps are also often used to control the flow of water (and the temperature of said flow) from other kinds of water outlets too, and the outlet may be located remotely or some distance away from the tap, such as e.g. a showerhead, or a bath spout, etc.
  • An example of such a lever-type mixer tap which might be used to control the flow (and temperature) of water from a showerhead or bath spout, which is remote from the tap itself, is shown in Fig 2.
  • arrow F i.e.
  • the tap will be initially turned on and a small flow rate of water will flow from the outlet. If (or as) the lever is then lifted further, the flowrate of water exiting the outlet will increase. When the lever has been raised as far as it will go, the flowrate of water exiting the outlet will be at a maximum. Conversely, lowering the lever (i.e. opposite to arrow F) will reduce the flowrate of water flowing from the outlet, and lowering the lever as far as it will go will ultimately turn the tap off.
  • a progressive mixer tap differs from the more general type of mixer tap described above in that, with a progressive mixer tap, whilst the user is (again) able to use the tap to control and adjust the temperature of the water exiting the water outlet, the user is usually unable to control or adjust the flowrate of the water exiting the outlet when the tap is on, or at least the user's ability to adjust the flowrate independently of water temperature is generally reduced in comparison with general mixer taps.
  • FIG. 3 An example of a progressive mixer tap is given in Fig 3.
  • a progressive mixer tap like the one shown in Fig 3 for example, there is generally only a single tap handle or knob which the user can grasp and turn about the tap axis to control the flow of water out of the water outlet associated with the tap (whatever this may be; e.g. bath spout, showerhead, etc).
  • this turning of the handle/knob is generally the only way that the handle/knob can move in normal operation of the tap.
  • the particular example progressive mixer tap shown is illustrated with the tap's turnable knob 3 in its "fully off" position.
  • knob 3 If the knob 3 is turned (about the axis A) by a small initial amount in the direction indicated by arrow T2 (i.e. clockwise) from its "fully off” position, water will begin flowing out of the associated water outlet. When the knob 3 is in this slightly/initially turned position, the temperature of the water flowing out of the outlet will be “full cold”. However, if (or as) the knob 3 is turned progressively further in the direction of arrow T2, the relative proportion of the water flowing from the outlet that comes from the hot water supply will increase commensurate with the amount that the knob 3 has been turned, such that the temperature of the water flowing out of the outlet will increase.
  • progressive mixer taps are often (and they are increasingly being) used because, by providing only a single tap handle or knob that can be turned to adjust water temperature, they may take up less room and/or they be less obtrusive and/or they may be aesthetically preferable, compared to providing two separate taps for hot and cold water respectively, or even in comparison with other forms of mixer taps like e.g. the more conventional mixer taps described above in which a (potentially bulky or less elegant looking) lever-like handle may be needed. Aesthetics, therefore, are often a large part of the reason why progressive mixer taps are used or chosen instead of other forms of taps (and also why they have become popular).
  • a tap including but not necessarily limited to a progressive mixer tap
  • a tap could be provided with improved (or at least different) overall aesthetics compared to traditional tap handles, norms, etc, and this includes improved (or at least different) functional aesthetics (the term "functional aesthetics" here is intended to refer to the impression or sensation or overall "feel” associated with the tap's function and movement, as perceived by the user).
  • the invention resides broadly in a tap assembly including:
  • an actuation member associated with the flow control mechanism the actuation member being adapted to rotate about an axis thereof, wherein rotation of the actuation member actuates the flow control mechanism
  • a handle portion operatively connected to the actuation member such that, in use, a substantially linear movement of the handle portion causes rotation of the actuation member.
  • the flow control mechanism may be of any suitable form. Preferably, however, the flow control mechanism may be adapted to control the flow of fluid through the assembly.
  • the flow control mechanism may comprise a tap valve, such as a valve for a hot water tap or a cold water tap (e.g. a conventional "jumper" -type valve).
  • the actuation member may be part of the valve and may extend from a portion of the valve, although the actuation member should also be a rotatable relative to other parts of the valve.
  • the tap assembly may also include a housing inside which at least a portion of the valve is received and housed when the tap assembly is assembled and installed for use.
  • the flow control mechanism may comprise a mixer cartridge for a mixer tap, including a progressive mixer tap cartridge.
  • the actuation member may form part of the cartridge and may extend from a portion of the cartridge, although the actuation member should also be rotatable relative to other parts of the cartridge.
  • the tap assembly may also include a housing inside which at least a portion of the cartridge is received and housed when the tap assembly is assembled and installed for use.
  • the tap assembly may further include a means for securing the valve/cartridge within the housing, such that, when the tap assembly is assembled and installed for use, the valve/cartridge is substantially immovable relative to the housing, albeit the actuation member should still be rotatable about an axis thereof relative to other parts of the valve/cartridge.
  • the means for securing the cartridge within the housing may include a fastener (such as a lock nut or the like) which is operable such that, after the cartridge has been correctly positioned within the housing, the lock nut can be screwed into the housing (or into a portion thereof) to (either by itself, or together with one or more other components or features) secure the cartridge (except for the actuation member) in position.
  • a fastener such as a lock nut or the like
  • the flow control mechanism comprises a mixer tap cartridge
  • the mixer tap cartridge includes two inlets (typically, a cold water inlet and a hot water inlet) and a single outlet (through which the desired mix of hot and cold water flows to a fluid dispensing device, such as a tap, faucet, shower head, nozzle or the like, or a combination thereof).
  • a fluid dispensing device such as a tap, faucet, shower head, nozzle or the like, or a combination thereof.
  • size of the flow control mechanism may vary depending on the duty of the tap assembly. It will be understood that, by “size of the flow control mechanism” it is meant the maximum volume flow rate of fluid through the flow control mechanism. For instance, some tap assemblies (such as those used for showers or baths) may require a higher maximum volume flow rate than tap assemblies used for other purposes (such as in a bathroom sink) where a relatively low flow of fluid is sufficient.
  • the actuation member may be of any suitable form. In a preferred embodiment of the invention, however, the actuation member may comprise an elongate member. In use it is envisaged that the actuation member may operatively connect the flow control mechanism and the handle portion. In embodiments of the invention in which the actuation member comprises an elongate member, the actuation member may be operatively connected to the flow control mechanism at a first end thereof, and operatively connected to the handle portion at a second end thereof. The actuation member may be directly or indirectly connected to the flow control mechanism and/or the handle portion.
  • the actuation member may comprise a rod, spindle, shaft or the like.
  • a first end of the actuation member may be connected to, or at least partially received within, the flow control mechanism.
  • rotation of the actuation member may actuate a valve member within the flow control mechanism to either increase or decrease the flow of fluid through the flow control mechanism.
  • the actuation member may form the valve member in the flow control mechanism, such that rotation of the actuation member either increases or decreases the flow of fluid through the flow control mechanism.
  • the actuation member may rotate about any suitable axis. Preferably, however, the actuation member may rotate about its principal axis. It is envisaged that the principal axis of the actuation member may be its longitudinal axis.
  • the actuation member may be rotatable between two extremes of rotation, namely an initial position ("fully closed”) and a final position ("fully open”).
  • the fully closed position may correspond to the position at which no fluid may flow through the flow control mechanism
  • the fully open position may correspond to the position at which the maximum volume flow rate of fluid is flowing through the flow control mechanism.
  • the fully closed position may correspond to the position at which no fluid may flow through the flow control mechanism, but the fully open position may correspond to the position at which only hot water flows through the flow control mechanism.
  • rotation of the actuation member may start from the fully closed position (no flow) through a position at which only cold water flows through the flow control mechanism to the fully open position in which only hot water flows through the flow control mechanism.
  • the degree of rotation between these two positions may be less than 360°, so that the actuation member cannot be rotated by more than one full revolution. In some preferred embodiments of the invention, the degree of rotation between the two positions may be approximately 180° or less.
  • the handle portion may be of any suitable form.
  • the handle portion is adapted to move in a linear manner between a first condition and a second condition.
  • the first condition corresponds to the initial fully closed position of the actuation member
  • the second condition corresponds to the final fully open position of the actuation member.
  • the linear movement of the handle portion may be achieved using any suitable technique.
  • linear movement of the handle portion may be driven using one or more motors or the like.

  • mounting plate 1 1 is connected to both the support (not shown) and the housing 18 via screws 35.
  • FIG. 1 1 an isometric view of a tap assembly 16 according to an embodiment of the invention is shown.
  • the cover portion 25 has been removed from the movement portion 12.
  • the carriage portion 26 is provided with a rack portion 36 including a number of teeth 37 that mesh with the teeth 38 of pinion 33, thereby converting the linear movement of the carriage portion 26 to a rotational movement of the pinion 33.
  • the teeth 38 of the pinion 33 mesh with a gear wheel (obscured) connected to the spindle 22, thereby causing rotation of the spindle and actuation of the mixer tap cartridge (obscured).
  • Figure 12 a detailed view of a portion of the tap assembly is illustrated. Specifically, Figure 12 illustrates the manner in which the teeth 37 of the rack portion 36 mesh with the teeth 38 of the pinion 33 such that, as the carriage portion 26 moves in a linear motion, the linear motion is converted into rotational movement of the pinion 33.
  • the teeth 38 of the pinion 33 mesh with the teeth 39 of a gear wheel 32 that is positioned on the spindle 22. Rotational movement of the pinion 33 results in rotational movement of the gear wheel 32, thereby also resulting in rotation of the spindle 22 about its longitudinal axis.
  • movement of the carriage portion 26 is in a direction that is substantially perpendicular to the axis about which the spindle 22 rotates. Rotation of the spindle 22 about its longitudinal axis in turn results in actuation of the mixer tap cartridge.
  • the temperature indication markings on the upper surface of the base ring could be replaced by flow rate indication markings.
  • the flowrate indication markings which allow the user to know e.g. how far the tap currently is between "no flow” and "full flow" are still completely hidden when the tap is not in use and therefore do not hinder or detract from the overall intended visual aesthetic or design appearance or "feel".
  • the present invention will be applied to taps which are used to control the flow of water (i.e. water taps), the invention is not necessarily limited to this. That is, the invention is potentially also applicable to taps which are used to control the flow of other forms of liquids or fluids (including gases), such that the invention could potentially even be used on, for example, a handle/dial used to control gas flow in an individual gas burner on a gas cooktop or barbecue. And in fact, the invention is potentially even applicable to other forms of dials which do not control or regulate the flow of fluids at all.
  • the invention could potentially even be used to operate control dials, knobs or the like on electrical appliance such as electric ovens, electric cooktops/stovetops, fans, heaters, etc.
  • at least one turnable dial or handle or knob is typically provided to allow the user to control or regulate the operation of the device in question in some way - i.e. there is a dial or the like that can be turned by the user to allow the device (or the relevant section or part or element of the device) to be turned more on or more off, or to change its more or manner of operation, etc.
  • the portion of the dial handle which the user grasps in order to turn it is in turn connected to a rotatable spindle or shaft or the like which in turn connects to the internal functional workings that control the operation of the device.
  • the visual appearance and ascetics of these other kinds of devices is also hugely important to their overall appeal, and therefore these things could potentially benefit in much the same way from the aesthetic, and functional aesthetic, improvements provided by the invention, as has been described above in the context of sinks and bathrooms and the like.
