Definitions
- the present invention relates to waste outlet fittings, particularly for a bath or a basin.
- the conventional plug on a chain for closing a basin outlet has a number of drawbacks, not least of which is that the plug can, by accident or design, become detached from the chain, or the chain become detached from the basin.
- a further drawback of the plug and chain arrangement is that people with restricted dexterity or strength can have difficulty pressing the plug into, or releasing the plug from, the basin or bath outlet.
- Captive plugs such as described in US Patent No 4,457,030, the disclosure of which is incorporated herein by reference, overcome a number of these disadvantages, as the plugs are far more difficult to remove from the basin.
- a captive plug has a plug element retained in a housing.
- the plug element is movable between a closed position and an open position by pressing on one side of the plug, causing the plug to rotate within the housing about a horizontal transverse axis.
- captive plugs have associated drawbacks: for instance, after the plug is moved to the open position, liquid flowing through the outlet can cause the plug to rotate back towards the closed position. Additionally, when pressing on the edge of the plug to rotate the plug to the open position, a user's finger can enter and even become stuck in the basin outlet.
- a waste outlet fitting for a basin or bath or the like comprising:
- the provision of the actuation member makes opening and closing the waste outlet easier and safer, and the weight of the actuation member assists in preventing an open plug from rotating to the closed position under the action of the liquid being discharged from the basin or bath.
- the plug is in the form of a circular disc. At least a portion of the circumferential edge of the disc may, in the closed position, engage a seat defined by the housing to form a seal. Using a disc which forms an edge seal with a surface of the housing creates a seal around the entire periphery of the plug.
- the plug edge defines a convex surface
- the housing defines a complementary concave seat. Providing complementary curved surfaces on the edge of the plug and the housing maximises the sealing area between the plug and the seat to improve the performance of the waste outlet fitting.
- the plug may be moved from the closed position towards the open position by applying a lateral force to the actuation member sufficient to rotate the plug about an axis transverse to the longitudinal axis of the throughbore.
- the actuation member is most preferably located towards the centre of the plug.
- the actuation member is aligned with the longitudinal axis of the throughbore. Locating the actuation member towards the centre of the plug, particularly along the longitudinal axis of the throughbore, means the plug may be moved by pushing the actuation member in any direction transverse to the longitudinal axis of the throughbore, rather than pulling or pushing on the actuation member in a direction parallel to the throughbore axis.
- This method of operation has the advantage that the actuation member does not need to be gripped, or moved with any degree of precision, with the result that it can be easily manipulated by, for example, a person with restricted hand mobility, a person wearing protective gloves, or using a tool or implement. Furthermore, the possibility of a user's fingers entering the waste whilst the plug is being opened or closed is greatly reduced.
- the actuation member may be connected to the plug by means of a threaded engagement.
- the actuation member may include a threaded male portion, which is engageable with a female threaded portion on the plug.
- the plug may include a threaded boss, which is engageable with a threaded receiving portion on the actuation member.
- the actuation member may be welded to the plug or formed integrally with the plug. It will be understood any suitable method of attaching the actuation member to the plug may be employed.
- the actuation member is secured to the plug by means of a separate screw.
- the plug may define an aperture through the centre of the plug to permit the insertion and removal of securing means, typically a screw-bolt, for securing the waste outlet fitting to the waste outlet of the bath or basin.
- securing means typically a screw-bolt
- waste outlet fittings are provided with a grid or spider, located within the throughbore, which acts as a coarse filter to prevent large objects entering the waste pipe work.
- the screw-bolt may pass through a central aperture in the grid or spider to engage a portion of the waste outlet or another portion of the waste outlet fitting to secure the waste outlet fitting to the bath or basin or the like.
- the actuation member is of a relatively dense and inert material, such as brass, stainless steel or heavy duty polymeric materials.
- a dense material such as brass will raise the combined centre of gravity of the plug and actuation member to assist in retaining the plug and actuation member in the open position as a liquid flows through the outlet.
- the inert material may be chrome plated.
- a chrome plate finish can be more aesthetically pleasing.
- the plug and housing are of a relatively dense and inert material, such as brass, stainless steel or heavy duty polymeric materials
- the plug is snap-fitted or pressed into the housing.
- the housing may include an overflow outlet.
- a waste outlet fitting is provided which combines ease of use and reliability of performance.

- FIG 1 a perspective view of a basin waste outlet fitting, generally indicated by reference numeral 10, in a closed configuration, and to Figure 2, a side view of the waste outlet fitting 10.

Abstract
Description
- The present invention relates to waste outlet fittings, particularly for a bath or a basin.
- The conventional plug on a chain for closing a basin outlet has a number of drawbacks, not least of which is that the plug can, by accident or design, become detached from the chain, or the chain become detached from the basin. A further drawback of the plug and chain arrangement is that people with restricted dexterity or strength can have difficulty pressing the plug into, or releasing the plug from, the basin or bath outlet.
- Captive plugs, such as described in US Patent No 4,457,030, the disclosure of which is incorporated herein by reference, overcome a number of these disadvantages, as the plugs are far more difficult to remove from the basin.
- A captive plug has a plug element retained in a housing. The plug element is movable between a closed position and an open position by pressing on one side of the plug, causing the plug to rotate within the housing about a horizontal transverse axis. However, captive plugs have associated drawbacks: for instance, after the plug is moved to the open position, liquid flowing through the outlet can cause the plug to rotate back towards the closed position. Additionally, when pressing on the edge of the plug to rotate the plug to the open position, a user's finger can enter and even become stuck in the basin outlet.
- Those with restricted dexterity can also find known captive plugs difficult to manipulate.
- It is an object of at least one embodiment of the present invention to provide an improved waste outlet fitting which overcomes at least one problem associated with the prior art.
- According to a first aspect of the present invention there is provided a waste outlet fitting for a basin or bath or the like, the waste outlet fitting comprising:
- a housing for sealingly mounting within a waste outlet, the housing defining a throughbore;
- a plug captively received by the housing, the plug being rotatable between a closed position wherein the throughbore is closed and an open position wherein the throughbore is at least partially open; and
- an actuation member extending from the plug for use in rotating the plug between the closed and open positions.
- In a preferred embodiment, the provision of the actuation member makes opening and closing the waste outlet easier and safer, and the weight of the actuation member assists in preventing an open plug from rotating to the closed position under the action of the liquid being discharged from the basin or bath.
- Preferably, the plug is in the form of a circular disc. At least a portion of the circumferential edge of the disc may, in the closed position, engage a seat defined by the housing to form a seal. Using a disc which forms an edge seal with a surface of the housing creates a seal around the entire periphery of the plug.
- Preferably, the plug edge defines a convex surface, and the housing defines a complementary concave seat. Providing complementary curved surfaces on the edge of the plug and the housing maximises the sealing area between the plug and the seat to improve the performance of the waste outlet fitting.
- The plug may be moved from the closed position towards the open position by applying a lateral force to the actuation member sufficient to rotate the plug about an axis transverse to the longitudinal axis of the throughbore.
- The actuation member is most preferably located towards the centre of the plug. In one embodiment, the actuation member is aligned with the longitudinal axis of the throughbore. Locating the actuation member towards the centre of the plug, particularly along the longitudinal axis of the throughbore, means the plug may be moved by pushing the actuation member in any direction transverse to the longitudinal axis of the throughbore, rather than pulling or pushing on the actuation member in a direction parallel to the throughbore axis. This method of operation has the advantage that the actuation member does not need to be gripped, or moved with any degree of precision, with the result that it can be easily manipulated by, for example, a person with restricted hand mobility, a person wearing protective gloves, or using a tool or implement. Furthermore, the possibility of a user's fingers entering the waste whilst the plug is being opened or closed is greatly reduced.
- The actuation member may be connected to the plug by means of a threaded engagement. The actuation member may include a threaded male portion, which is engageable with a female threaded portion on the plug. Alternatively, the plug may include a threaded boss, which is engageable with a threaded receiving portion on the actuation member.
- In a further alternative, the actuation member may be welded to the plug or formed integrally with the plug. It will be understood any suitable method of attaching the actuation member to the plug may be employed.
- In one arrangement, the actuation member is secured to the plug by means of a separate screw.
- The plug may define an aperture through the centre of the plug to permit the insertion and removal of securing means, typically a screw-bolt, for securing the waste outlet fitting to the waste outlet of the bath or basin.
- Many waste outlet fittings are provided with a grid or spider, located within the throughbore, which acts as a coarse filter to prevent large objects entering the waste pipe work. The screw-bolt may pass through a central aperture in the grid or spider to engage a portion of the waste outlet or another portion of the waste outlet fitting to secure the waste outlet fitting to the bath or basin or the like.
- Preferably, the actuation member is of a relatively dense and inert material, such as brass, stainless steel or heavy duty polymeric materials. A dense material such as brass will raise the combined centre of gravity of the plug and actuation member to assist in retaining the plug and actuation member in the open position as a liquid flows through the outlet.
- The inert material may be chrome plated. For materials such as brass, a chrome plate finish can be more aesthetically pleasing.
- Preferably, the plug and housing are of a relatively dense and inert material, such as brass, stainless steel or heavy duty polymeric materials
- Preferably, the plug is snap-fitted or pressed into the housing.
- The housing may include an overflow outlet.
- By virtue of the present invention, a waste outlet fitting is provided which combines ease of use and reliability of performance.
