The member 15 may alternatively be secured to the member 11 by grub-screws, a helical wide spring, or by a bayonet fastening. <IMAGE>

Description

SPECIFICATION Waste outlet members The invention relates to waste outlet members and to methods of their renewal.

In many liquid receptacles, such as baths and hand basins, the waste outlet includes a waste outlet member comprising a flange extending around the outlet and having a central aperture from which depends a tube forming the start of the outlet. The member is commonly made of a non-ferrous metal or a plastics material. When the receptacle is cleaned, particularly if the receptacle is an enamel bath and acids are used in the cleaning, the member can be scraped, scratched or eaten away by chemicals and in due course presents an unsightly appearance.

For this reason, it can be necessary to replace the waste outlet member. This involves dismantling the waste outlet member and replacing it with a new member and, in the case of a bath, can involve many hours or even days of work and is therefore both time consuming and expensive.

According to a first aspect of the invention, there is provided a waste outlet member for fitting over an existing waste outlet member of a liquid receptacle, the existing waste outlet member comprising a flange extending around the outlet and having a central aperture from which depends a tube forming the start of the outlet, the waste outlet member also comprising a flange whose minimum diameter is at least equal to the maximum diameter of the existing outlet and having a central aperture from which depends a tube whose outer diameter is less than the diameter of the tube of the existing waste outlet member so that the waste outlet member can be secured over the existing waste outlet member to provide a new waste outlet.

Preferably the waste outlet member also includes a mechanical device for fastening securely the new waste outlet member to the existing waste outlet member.

In the case where the existing waste outlet member includes a grid located in the associated tube and lying in a plane normal to the axis of the tube, the mechanical device may comprise at least one limb depending from the end of the tube of the new waste outlet member and associated with a part for locking engagement with the grid.

The part may comprise a lug on the or each limb so arranged that the lug and limb pass through the grid, with the or each lug, on rotation of the new waste outlet member relatively to the existing waste outlet member, engaging behind the grid to secure the new waste outlet member to the existing waste outlet member.

The or each lug member may be mounted on a sleeve in screw threaded engagement with the associated limb to allow adjustment of the position of the lug along the limb to accommodate grids of differing axial locations along the tube.

Alternatively, the lug may be mounted on a slide movable in a guidewayformed on the associated limb and lockable relatively to the associated limb in any required position.

The part need not necessarily comprise a lug, it could comprise one of a series of serrations provided on the or each limb with the or each limb being inserted through the grid and one of the serrations engaged with the grid.

Preferably, two limbs are provided depending from diametrically opposed ends of the tube.

Alternatively, the mechanical device may be one or more grub screws provided in the tube of the waste outlet member and screwable into engagement with the tube of the existing waste outlet to complete said mechanical engagement.

In yet another embodiment, the mechanical device may comprise a helical wire spring extending around the exterior of the tube of the new waste outlet member and having a free end which, when the waste outlet member is rotated, engages a grid of an existing waste outlet member to complete said mechanical interengagement.

In yet a further embodiment, the mechanical device may comprise brackets formed on the undersurface of the flange of the waste outlet member and provided with screws for engagement with the flange of the existing waste outlet member to complete said mechanical engagement.

According to a second aspect of the invention, there is provided a liquid receptacle having an existing waste outlet member comprising a flange extending around the outlet and having a central aperture from which depends a tube forming the start of the outlet, the existing waste outlet member being covered by a waste outlet member of any of the kinds according to the first aspect of the invention.

According to a third aspect of the invention, there is provided a method of forming a new waste outlet for a liquid receptacle having an existing waste outlet comprising a flange extending around the outlet and a central aperture from which depends a tube forming the start of the outlet, the method comprising securing over the existing waste outlet member, a new waste outlet member of any of the kinds according to the first aspect of the invention.

The securing may be by use of an adhesive or by mechanical means.

The following is a more detailed description of some embodiments of the invention, by way of example, reference being made to the accompanying drawings, in which: Figure 1 shows a waste outlet of a bath or wash basin having an existing waste outlet member and a first form of new waste outlet member secured thereto.

Figure 2 is a plan view of the new and existing waste outlet members of Figure 1.

Figure 3 shows various views of the part of the new waste outlet member shown in Figures 1 and 2, and Figures 4, 5, 6, 7, 8, 9 and 10 show respective further forms of new waste outlet members.

Referring first to Figures 1 to 3, an enamel bath or wash basin 10 has a waste outlet formed by an existing waste outlet member 11 of a non-ferrous metal or a plastics material. The existing waste outlet member 11 comprises a flange 1 2 having a central aperture from which depends a tube 13 forming the start of the outlet. Within the tube, is a grid 14 (see Figure 2) which lies in a plane normal to the axis of the tube.

When the bath or wash basin 10 is cleaned, particularly where acids are used in the cleaning process, the existing waste outlet member 11 can be scoured, scratched or subject to chemical attack which can render it unsightly.

In order to remove this unsightliness, a new waste outlet member 1 5 is secured over the existing waste outlet member 11.

The new waste outlet member 1 5 is made of a non-ferrous metal or a plastics material and comprises a flange 1 6 having a circular circumference whose diameter is greater than the diameter of the flange 12 of the existing waste outlet 1 The flange 1 6 has a central aperture from which depends a cylindrical tube whose exterior diameter is less than the interior diameter of the tube 1 3 of the existing waste outlet member 11.

Two threaded rods 1 8 depend from diametrically opposed lower edges of the tube 1 7 and are passed through the grid 14 in the tube 1 3 of the existing waste outlet member 11. A sleeve 1 9 (see Figure 3) is in screw threaded engagement with each rod 1 8 and carries an associated lug 20. The position of the sieeves on the rods is adjusted by screwing them along the rods until the lugs are just at the level of the under surface of the grid 14 when the new waste outlet member is placed over the existing waste outlet member 11.The new waste outlet member 1 5 is then rotated relatively to the existing member 11 so that the lugs slide beneath the grid (see Figure 2) to firmly lock the new member 1 5 to the old member 11.

A layer of putty or a similar jointing compound (not shown) is preferably provided between the two members 11, 1 5.

In this way, the bath or basin is provided with a new waste outlet member, thus improving its appearance. The new waste outlet member can be positioned quickly and cheaply without the bath or wash basin having to be taken out of service for any significant length of time. If the new waste outlet member also becomes unsightly, it can be quickly and easily replaced. In the further embodiments of the new waste outlet member now to be described with reference to Figures 4 to 10, parts common to Figures 1 to 3 and to Figures 4 to 10 will not be described in detail and will be given the same reference numerals.

In the embodiment of Figure 4, the tube 1 7 of the new waste outlet member 1 5 is provided with four grub screws 21 equiangularly spaced therearound and extending therethrough in a radial direction. The new waste outlet member 1 5 is placed over the existing waste outlet member 11 with the grub screws 21 retracted and the screws are then screwed into engagement with the tube 1 3 of the existing waste outlet member 11 to lock the two members firmly together.

In the embodiment of Figure 5, the tube 17 of the new waste outlet member has two limbs 22 depending from diametrically opposite edges.

Each limb is formed with serrations 23 and the limbs are inserted through the grid 14 (not shown in Figure 5) of the existing waste outlet member.

The new waste outlet member is then turned to engage the serrations with the grid 14 thus firmly locking the two members together. The provision of a number of serrations allows the new waste outlet member of Figure 5 to be used with existing waste outlet members having grids at differing distances down the tube 1 3.

In the embodiment of Figure 6, a bracket 24 is provided which has a horizontal limb and a vertical limb carrying a lug 25. The horizontal limb is fixed to the flange 1 2 of the existing waste outlet member 11 so that the vertical limb extends down the tube 1 3 and the lug extends radially. A second such bracket is secured at a diametrically opposed position.

The tube 17 of the new waste outlet member 1 5 is provided with a diametrically opposed bayonet type fittings 26 dimensioned to allow the lugs to pass into the fittings and then engage in the fittings on rotation of the new member 1 5 relatively to the existing member 11 to secure the two members 11, 1 5 together.

In the embodiment of Figure 7, an epoxy resin 26 is provided between the new waste outlet member 1 5 and the existing waste outlet member 11 so securing the two together. The use of this resin may obviate the need for the use of putty or a similar sealing material.

In the embodiment of Figure 8, two diametrically opposed limbs 27 extend from diametrically opposed lower edges of the tube 17 of the new waste outlet member 1 5. Each limb is provided with a longitudinal slot 28 which forms a guide for a slide 29 carrying a lug 30. A screw 31 allows the slide to be fixed in any position along the slot 28.

In this embodiment of the new waste outlet member 15, the lugs are positioned and the member fixed relatively to the existing waste outlet member in the same way as the embodiment described above with reference to Figures 1 to 3.

In the embodiment of Figure 9, a helical wire spring 32 is coiled around the exterior of the tube 1 7 of the new waste outlet member 1 5. The lower end 33 of the spring is left free and, as the tube 17 is inserted into the tube 1 3 of the existing waste outlet member 11, the new member 1 5 is rotated.

The end 33 of the spring 32 catches the grid 14 and coils beneath it so firmly engaging the two members 11,15.

Finally, in the embodiment of Figure 10, two brackets 34 are provided on the under surface of the flange 16 of the new waste outlet member 1 5.

Screws 35 are screwed at appropriate positions in the flange 1 2 of the existing waste outlet member 11 and the brackets are then engaged with the screws to hold the new waste outlet member in firm engagement with the existing waste outlet member 11.

It will be appreciated that the flanges 12, 1 6 need not be circulat; they could be of any convenient shape. In addition, the tubes 13,17 need not be circular; they could be of any suitable shape.
