Definitions

  • the present invention relates to a valved outlet for use in filling a bath.
  • the present invention aims to provide a device so that water can be left to fill a bath and the flow of water can be turned off automatically when the bath is filled to a desired level.
  • a device for filling a bath comprising: a housing having a channel therethrough and an inlet and an outlet, valve means operable to close the outlet, a float, means for supporting the float in the bath, and means responsive to the level of the float to shut the valve means when the float reaches a predetermined level.
  • the float is mounted on an arm that is pivotally connected to the housing, and the movement of the arm as the float rises closes the valve.
  • the float is mounted on a first end of the arm outside the housing, the second end of the arm extending into the housing; the device further comprising a closure member that is mounted on or adjacent to the second end of the arm that is movable to block the channel.
  • the closure member, arm and float are arranged so that when the bath is empty the arm hangs downwards under the weight of the float and in this position the closure member clears the water channel allowing the flow of water through the outlet and as the float rises the arm moves thereby moving the closure member in the channel and closing the outlet.
  • the outlet of the present invention may be permanently incorporated in a tap for the bath but preferably includes a tap adaptor arranged to mount the valved outlet onto an existing tap.
  • a further connection may be provided from the channel defined by the housing to a second tap.
  • the outlet functions as a "mixer” outlet, enabling the provision of water at a desired temperature.
  • a separate valved outlet may be provided for each of the hot and cold water taps.
  • Fig. 1 shows a partly sectioned side elevation of a first embodiment of the invention
  • Fig. 2 shows a partly sectioned side elevation of a second embodiment of the invention.
  • Fig. 3 shows a partly sectioned side elevation of a third embodiment of the invention in the open and closed positions.
  • Fig. 1 shows a valved outlet for use in the water supply to a bath and includes a generally cylindrical housing 1 which is injection moulded from plastics material.
  • An inlet 2 at the top of the housing is fitted onto a tap using a conventional tap ⁇ daptor mechanism 3 which screws down to secure the housing to the tap.
  • An outlet 4 is provided at the bottom of the housing.
  • the valve mechanism includes a closure member 5, which in position shown in Figure 1 makes a sealing fit with the inside of the housing 1 by closing the outlet 4.
  • the closure member 5 is mounted on an arm 6 which extends outside the housing through a slot 7.
  • a float 8 is mounted on the other end of the arm.
  • Means may be provided to adjust the position of the float 8 on the arm and/or to weight the float so as to adjust the level at which the valve is closed.
  • the valve may be mounted on a mixer tap or alternatively may be mounted on one of a hot and cold tap with a flexible pipe (not shown) connecting the outlet of the other tap to the housing 1.
  • the outlet itself functions as a mixer. It then has the advantage that the flow of water can be turned off without adjusting the relative positions of the taps and hence the temperature of the water from the outlet.
  • the outlet also offers the advantages when used by someone with restricted strength or dexterity, since the flow of water can be shut off simply by moving the float, without reguiring the twisting action necessary with conventional taps.
  • Fig. 2 shows a second embodiment in which the valved outlet is permanently incorporated in a bath tap 20.
  • the closure member is a plunger head 18 which in the closed position is seated in a seal ring 11.
  • the plunger head 18 is mounted on one end of an arcuate arm 12.
  • the arm 12 is pivotally mounted on the tap by a radial member 13.
  • a link 14 and spring 15 extend between the fair end of the arcuate arm 12 and the tap, on either side of the tap. The link and spring serve to spring-bias the arm to give an over centre action.
  • a depending extension 16 is also pivotally connected to the end of the arcuate arm 12.
  • the extension 16 hangs downwards into the bath.
  • An adjustable float 17 is concentrically mounted on the extension 16 and is adjustable to move upwards or downwards.
  • the plunger head 18 is initially in a position in which it is biased against the side of the tap leaving the outlet from the tap open. As the level of the water in the bath rises, it reaches a point at which the float begins to move upwards. Further upwards movement then causes the over centre action to move the plunger head into the position shown in Fig. 2, in which the head seals the outlet, preventing any further flow of water into the bath.
  • the links 14 and springs 15 bias the closure member 18 in this position.
  • Fig. 3 shows a further embodiment of the invention.
  • the device is fitted to an existing tap 30.
  • the device comprises a housing 40 into which the tap
  • a threaded shaft 41 is screwed through the housing.
  • the shaft 41 is rubber tipped 42 and is
  • the housing contains a rubber washer 44 positioned on a flange 45. There is an opening in the bottom of the housing containing a rubber seating 46.
  • the device is activated by a mechanism similar to that in the embodiment shown in Fig. 2.
  • a closure member 47 in the form of a plunger head is mounted on the end of an arcuate arm 48.
  • the arcuate arm is pivotally mounted on a radial member (not shown).
  • On the other end of the arm 48 is a cross piece 49.
  • a link 50 and spring 51 extend between the cross piece and the tap on either side of the housing.
  • An extension 52 and adjustable float 53 are also mounted on the end of the arcuate arm.
  • a cover 54 covers the knob 43 and the upper part of the housing.
  • the device is fitted to a tap 30 by clamping the end of the tap between the shaft 41 and the washer 44.
  • the cover 54 is then fitted.
  • the float When the bath is empty the float hangs downwards and the closure member 47 is biased against the inside of the housing 40 (position A) . In this position water can flow through the housing. As the bath fills the float 53 rises. This moves the closure member towards the seating 46. When the float reaches a predetermined level the closure member seals against the seating, thereby stopping the flow of water through the device (position B).
  • the mechanism may conveniently be an over centre mechanism. As the closure member moves from position A to B the orientation of the links 50 changes. This alters the bias of the springs 51 so that when the closure member
  • the shape of the washer 44 can be varied to suit different types of taps.
  • the device is retailed with a selection of washers.
