- a drainage base in accordance with aspects of the present invention as indicated could take the form of a shower tray 1 but also, where appropriate, may comprise a bathtub in which the bottom surface of that bathtub incorporates tactile elements to prevent slippage. This will be particularly useful in situations where slippage could be a problem, that is to say with elderly or less agile individuals and/or where the bathtub is utilised with a shower attachment to the tap fittings or an electric shower is used over the bathtub.
- the tactile elements' 5 must be robustly secured to the drain base such that they do not become detached or break the sealing effect of the drain base leading to leakage.
- the base 2 will generally be formed from a plastics material which is relatively hard such as an unfilled polyester.

Abstract
Description
- The present invention relates to drain bases and more particularly to drain bases provided as shower trays.
- It is known to provide a shower tray generally formed from a hard moulded plastics material in order to provide sufficient structural strength to accept a user's weight, as well as suitable configurational features for drainage of water to a drain aperture. It will be understood that water itself can create slippy conditions, but with the added effects of detergents and soaps in shower products a flat surfaced drain base for a shower may be dangerous. In such circumstances it is known to provide undulations in the form of ribs, dimples and other features to improve user grip.
- Although such features as dimples and ridges and grooves provide some improved grip, it will be understood that there is still a potential problem in that the feature cannot be too deep and will normally be relatively smooth. It will also be understood that introduction of such features into a generally relatively high strength structural base may cause problems with respect to providing initiation sites for cracking or poor formation processing in terms of material thickness at the bends and feature edges.
- In accordance with aspects of the present invention there is provided a drain base comprising a structural tray having apertures and tactile elements secured through the apertures to collectively define a non slip surface.
- Typically, the tactile elements are coupled together by an installation tree. Possibly, the installation tree adheres to the structural tray.
- Advantageously, the tactile elements adhere to the structural tray. Generally, the tactile elements provide a seal closing the apertures in the structural tray.
- Possibly, the tactile elements are tear drop shaped.
- Possibly, the structural tray has recesses to receive the tactile elements. Alternatively, the tactile elements rise above a structural tray.
- Possibly, the structural tray has stiffener members. Possibly, the stiffener members extend about the apertures.
- Advantageously, the structural tray incorporates a drain aperture. Possibly, a gasket is provided about the drain aperture. Advantageously, the gasket forms part of the installation tree.
- Typically, the structural tray is formed by a mould.
- Advantageously, the tactile elements are provided by locating the structural tray with a tactile element mould part associated about the apertures whereby tactile material for the tactile elements is injected into the tactile element mould part to extend through apertures for location of the tactile elements upon the structural tray.
- Advantageously, there is a tree mould part secured upon the opposite side of the apertures to the tactile element mould part and the tactile material injected through the tree mould part through the apertures to the tactile element mould part to form tactile elements in-situ. Typically, the tree mould part incorporates parts which define the installation tree for the drain base.
- Generally, the base is formed from an unfilled polyester plastics material.
- Generally, the tactile elements are formed from a relatively soft thermo plastic rubber.
- Generally, the structural tray and the tactile elements are formed from materials which fuse together.
- Also in accordance with aspects of the present invention there is provided a method of forming a drain base comprising forming a structural tray with apertures, applying a tactile element mould part to the structural tray and applying a tactile material through the apertures to form tactile elements in association with the structural tray.
- Normally, the drain base is as described above.
- Generally, the mould also includes applying a tree mould part on the opposite side of the structural tray to the tactile element mould part and applying the tactile material through the tree mould part.
- Embodiments of the present invention will now be described by way of example and with reference to the accompanying drawings in which:-
- Fig. 1 is a perspective view of a drain base such as a shower tray in accordance with aspects of the present invention;
- Fig. 2 is a schematic view of the drain based depicted in Fig. 1 with tactile elements removed;
- Fig. 3 is a schematic illustration of the bottom of the base illustrating an installation tree in accordance with aspects of the present invention;
- Fig. 4 is a schematic perspective cross section through a tactile element and installation tree in accordance with aspects of the present invention;
- Fig. 5 is a perspective view of tactile elements and installation tree in accordance with aspects of the present invention with a structural tray removed; and,
- Fig. 6 is a base perspective view of a drain base having an installation tree and base wall seal edge.
- As indicated above, it is known to form drain bases such as shower trays from mouldings incorporating ribs or dimples or other features in order to provide a non-slip grip capability. However, provision of a more tactile surface than possible with the generally unfilled hard polyester plastic materials which are used to form such drain bases would be advantageous. Fig. 1 provides a perspective view of a drain base in the form of a shower tray 1 comprising a
structural tray 2 incorporating a well 3 anddrain aperture 4. Thewell 3 on its bottom anti-slip surface incorporatestactile elements 5 secured in thestructural tray 2. As can be seen, thesetactile elements 5 have a generally tear drop shape but could have other shapes including diamond, triangle or circle dependent upon requirements. In short, the actual shape of each individualtactile element 5 as well as its distribution will generally be provided for aesthetic appearance effects and characteristics provided there is adequate drainage into theaperture 4 and, as indicated above, in accordance with aspects of the present invention provision of a surface having adequate anti-slip grip. As will be appreciated in a shower tray 1 thewell 3 will typically collect a reasonable volume of water as well as detergents and therefore the bottom surface incorporating thetactile elements 5 may become slippy. Thetactile elements 5 act to engage a user's foot in order to grip and therefore prevent slippage. - It will be understood a drainage base in accordance with aspects of the present invention as indicated could take the form of a shower tray 1 but also, where appropriate, may comprise a bathtub in which the bottom surface of that bathtub incorporates tactile elements to prevent slippage. This will be particularly useful in situations where slippage could be a problem, that is to say with elderly or less agile individuals and/or where the bathtub is utilised with a shower attachment to the tap fittings or an electric shower is used over the bathtub.
- It will be understood that the tactile elements' 5 must be robustly secured to the drain base such that they do not become detached or break the sealing effect of the drain base leading to leakage. It will also be understood that the
base 2 will generally be formed from a plastics material which is relatively hard such as an unfilled polyester. Compatibility with such hard plastics materials will generally be a necessity and therefore thetactile elements 5 will generally be formed from soft thermo plastic rubbers. In such circumstances a non slip nature is provided by thetactile elements 5 and the soft thermo plastic rubber will fuse and generally stick to the relatively hard unfilled polyester material. - Generally, the
tactile elements 5 will radiate outwardly from thedrain aperture 4 as depicted in Fig. 1. It will be understood typically there is a slight slope towards thedrain aperture 4 and therefore by provision oftactile elements 5 radiating out this flow towards theaperture 4 is not overly inhibited. - Fig. 2 illustrates the drain base 1 with tactile elements removed. In such circumstances, as can be seen, the bottom of the
well 3 incorporatesapertures 6 which, in accordance with aspects of the present invention, will be utilised in order to provide tactile elements in use. Generally, the tray is formed between mould parts with theaperture 4 as well as theapertures 6 thin section in comparison with the other parts of the tray 1. In such circumstances theaperture 4 can be cut out with an appropriate tool. Theapertures 6 may be drilled or otherwise cut out as required at desired locations in the tray 1. The formation of the tray 1 is a first moulding step in accordance with aspects of the present invention. This moulding step is similar to that utilised with previous drain bases but, as indicated previously, recesses, ribs, dimples or other features may be provided within the base of thewell 3 in order to provide some non slip nature. - In accordance with aspects of the present invention a second moulding stage is provided. Typically, this second moulding stage comprises applying within the well 3 (Fig. 1 and Fig. 2) a resilient element mould part. This resilient element mould part sits over the apertures 6 (Fig. 2) and defines each tactile element shape. Generally, the tactile element mould part is held in robust and normally compressive engagement with the surface of the formed
structural tray 2. In such circumstances, tactile element material can be injected through the apertures 6 (Fig. 2) or through the tactile element mould part itself in order to create the tactile elements required. - The approach described above with respect to creating the tactile elements may be messy in terms of introducing the tactile element material and may leave unsightly tell-tale signs on the tactile element if the material is injected through the mould itself or create waste on the other side of the aperture. Thus, in accordance with a preferred aspect of the present invention, an installation tree mould part is provided. This installation tree mould part will be presented on the opposite side to the tactile element mould part and again normally in compressive engagement. The installation tree mould part provides a network of pathways for tactile material to be presented to the aperture 6 (Fig. 2). Generally, the bottom surface of the
well 3 in the structural tray will be held in a compressive sandwich between the tactile element mould part and the installation tree mould part. The tactile material will pass through the network of spurs and branches of the installation tree mould part to pass through the apertures 6 (Fig. 2) in order to create the tactile elements in the tactile element mould part above theapertures 6. Once the installation tree mould part and the tactile element mould part are removed it will be understood that an upper surface will show the tactile elements presented in thewell 3 whilst below that surface the tactile element material remaining within the spurs and branches of the installation tree mould part will remain. As indicated above, generally the materials from which the structural tray is initially formed as well as the tactile element material will be compatible such that they fuse and create an appropriate seal in theaperture 6 and cause adhesion between the tactile element material, both through the tactile element engagement with the surface of the structural tray about theaperture 6, as well as between the remnant installation tree network created by the tactile material passing through the installation tree mould part. This will prevent water leakage through theaperture 6 and improve structural integrity and strength. - Fig. 3 illustrates a section of the underside of a drain base in accordance with aspects of the present invention. Where appropriate, similar reference numerals have been utilised for comparison. Thus, as can be seen around the
drain aperture 4, thetactile elements 5 radiate on one side of a well 3 surface and atree network 7 on the other side of resilient element material remaining after that material has passed through an installation tree mould part to squirt throughapertures 6 to define the tactile elements with an appropriate shape corresponding to the tactile element mould part. As can be seen, reinforcement orpresenter elements 8 can be provided aboutapertures 6. Theseelements 6 facilitate alignment of the installation tree mould part with theaperture 6 and also once the installation tree mould part has been removed provide some reinforcement below thetactile elements 5. It will be noted that provision of eachaperture 6 may provide initiation points for cracking in thetray 3. By provision of theelements 8 such cracking may be prevented or terminated. In the event of minor cracks it will be understood that, as indicated, the tactile element material will generally fuse with the material of the structural tray and so prevent significant seal breaches as a result of such cracking. - Fig. 4 illustrates a perspective view through a cross section of one
tactile element 5, atree 7 part in thewell 3 of a drain base in accordance with aspects of the present invention. As can be seen thetactile element 5 extends through to the upper surface of thewell 3 in order to facilitate an anti-slip nature to the base of thewell 3. Thetree network 7 extends below the surface of thewell 3 about a drain base. Typically, as illustrated, the bottom of the structural tray forming thewell 3 may have amound 9 or recess to facilitate keying between thetactile element 5 and the well and therefore the base in accordance with aspects of the present invention. As indicated, it is advantageous that the material chosen such that there is fusion between thetactile element 5 and the material of thewell 3. This fusion can be achieved on flat surface to surface mating, but may be enhanced by, as indicated, a surface contour whether that be through amound 9 or recess within which thetactile element 5 is located. Again, provision of anelement 8 about anaperture 6 through which the tactile material extends may be advantageous in creating the mould orrecess 9. - Fig. 5 illustrates
tactile elements 5 associated with atree network 7 formed as a result of the installation tree mould part as described previously to facilitate tactile element release and presentation through apertures to create theelements 5. For clarity, theelement 5 andtree network 7 are shown without the drain base surface which will generally separate them. As can be seen, theelements 5, as described previously, have a tear drop shape but other shapes can be provided. Most significantly in accordance with aspects of the present invention is the distribution for reinforcement of association in accordance with aspects of the present invention. Thetactile elements 5 will generally take the form of significant mouldings of tactile material which, as indicated, will be in good preferably fused association with the material of the drain base. Further anchoring will be achieved through the section of tactile material extending through theapertures 6 into the tray and furthermore, as indicated, thetree network 7 itself will generally adhere to the bottom surface of the drain base further enhancing adhesion to that base over a broad engagement surface. In such circumstances, theelements 5 will be robustly secured to the tray. - As indicated above, generally the drain base will incorporate a drain aperture. This drain aperture will be associated with drain elements to which pipework and other plumbing will be secured. In order to facilitate a seal, aspects of the present invention may provide a gasket ring either in a groove on one side, that is to say the bottom side, of the well utilising tactile material in accordance with the present invention, or if a groove and apertures are drilled about the
drain aperture 4 gasket rings may be provided on either side of thedrain aperture 4. Such gaskets may facilitate improved sealing about thedrain aperture 4 in use. - Normally, in view of cost aspects of the present invention will utilise a single moulding process in order to create the structural tray of relatively hard unfilled polyester material and then a second moulding stage to introduce tactile element material to form the
tactile elements 5 andtree network 7 as required in a second moulding step. However, it will be appreciated if it is desirable to provide tactile elements of different materials then a third moulding step may be provided where further tactile elements of a different material type may be introduced as a further mould tool part. - It will be understood that generally the tactile elements in accordance with aspects of the present invention will be of consistent shape and size for aesthetic appearance. However, where desirable and again for desired aesthetic appearance effects, different shapes and sizes of tactile elements may be provided. Furthermore, the tactile elements may incorporate a thermally reactive dye to indicate temperature. Thus, when the drain base is cold as a result of inactivity or cold water presence, the tactile elements may have one colour whilst when warmed to an appropriate temperature, due to warm water incident upon the tactile elements, then a second colour may be created. Thus, providing an indication that the shower is ready for use. Furthermore, such a colour change may be used with babies and the infirm to indicate that the shower or bath has water at a safe temperature.
- As indicated above, generally a structural tray will be constructed in accordance with the present invention and then apertures 6 provided through which resilient elements will be created and anchored to the structural tray by injection of tactile element material. In such circumstances, positioning of the
apertures 6 may be varied to enable different tactile element distributions and shapes to be provided. Alternatively, a standard distributional pattern ofapertures 6 may be provided and then through appropriate shaping tactile elements introduced into a desired pattern. Thus, by a bespoke distribution ofapertures 6 or a standard pattern distribution ofapertures 6 different tactile element patterns can be created for aesthetic effect or to meet an individual user's requirements such as presenting a corporate pattern or logo through the distribution of tactile elements in the well. - Provision of a second moulding step allows other features to be incorporated into a drain base. Thus, as illustrated in Fig. 6 when an
installation tree 17 is provided by the moulding process it will be understood that agasket seal 28 for adrain aperture 24 could also be formed and anedge seal 29 formed about the edge of a base structural tray 22. Theseseals - Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
