Description

Liquid Director

FIELD OF TI-IF INVENTION

The present invention relates to a liquid director and to a worktop with a liquid S director attached to the bottom face of the work-surface for improved liquid management.

BACKGROUND OF THE INVENTION

If water is present on a work-surface (e.g. a kitchen work-surface) to the point where it is able to run off the work-surface and travel around the front edge, depending on the amount of water and the rate at which it flows, it has the ability to travel along the front edge profile of the work-surface and can continue to travel underneath the work-surface due to gravity and surface tension effects.

Water travelling under a work-surface will stop once it comes into contact with something. for example a drawer or door, but will then continue to proceed downwards. If liquid is left to travel unimpeded, it can cause damage to doors, drawers, fascias, items in cabinets, plinths and flooring.

Many known post-formed laminate worktops are manufactured to include a drip strip' on the bottom face of the work-surface, which is typically a machined groove with the purpose of impeding liquid from travelling past the strip under a worktop.

This groove however, is often filled with a glue to reduce water ingress, rendering the drip strip wholly or partially ineffective and causing it to fail in its purpose of impeding liquid travel. In addition, this approach does not lend itself to being retro-fitted to existing worktops.

The present invention seeks to overcome or at least mitigate the problems of the prior art.

SUMMARY OF THE INVENTION

A first aspect of the present invention provides a worktop comprising: a work-surface, to be arranged substantially horizontally in use and having a top surface, front longitudinal edge and an underside comprising at east one recess; a worktop item.

located below the work-surface; a separate Uquid director having an upper mounting portion comprising at least one resilient formation mounted to a recess in the underside of the work-surface and at least one projection arranged to extend generally downwardly therefrom.

This arrangement improves Uquid management by providing a physical barrier to liquids; impeding liquid travel and directing liquid away from any below work-surface items, such as cabinets and drawers. The upper mounting portion enables the liquid director to be easily installed with no special skills or tools required, and then to remain securely fixed in place after installation and during use while directing any liquids running down the worktop.

Preferably, the at least one recess is a continuous longitudinal recess. This means that the upper mounting portion can be mounted to the recess parallel with the entire longitudinal edge of the worktop, providing protection from liquid over the entire At least one resilient formation can comprise at least one limb that engages a wall of a recess, holding the liquid director in place under the worktop. Preferably, at least one resilient formation is dimensioned such that during insertion into a recess the formation is arranged to compress, in order to increase the ease of insertion. This enables the liquid director to be easily inserted by a user, but more difficult to then pull out again, creating a good seal as well as securely holding the liquid director in place when in use directing liquids.

More preferably, the at least one resilient formation comprises a substantially vertical portion with a p'urality of projections that engage with a wall of a recess, holding the liquid director in place under the worktop. The or each recess may comprise a mouth at a section of the recess proximate the underside of the work-surface, and one or more of the plurality of projections can extend substantially downwards, towards the recess mouth. A top section of the at least one resilient formation can taper to a point.

The upper mounting portion of the liquid director can further comprise one or more sections that are resiliently biased towards the underside of the worktop, in order that the one or more sections can stay in contact with the underside of the worktop and create a seal. This may increase the integrity of the seal between the liquid director and the work-surface and helps prevent liquid and dirt ingress.

The at least one resilient formation can even further comprise a bottom section of a substantially similar width to the recess in order that a seal can be created between the formation and the recess. As the wider part is so similar in size to the recess, a very strong seal is created, further helping to prevent liquid and dirt ingress.

A second aspect of the present invention provides a worktop comprising: a work-surface. to be arranged substantially horizontally in use and having a top surface, front longitudinal edge and an underside; a worktop item, located below the work-surface; a separate liquid director having an upper mounting surface for mounting to the underside of the work-surface and at least one projection arranged to extend generally downwardly therefrom, wherein the liquid director is mounted via the upper mounting surface to a bottom face of the work-surface located at a position laterally closer to a front longitudinal edge of the work-surface than the bdow-work-surface item, so as to deflect spilled This arrangement also improves liquid management by providing a physical barrier to liquids; impeding liquid travel and directing liquid away from any below work-surface items, such as cabinets and drawers. By locating the liquid director at a position laterally doser to a longitudinal edge of the work-surface than any Mow work-surface items, liquids are directed away from any below work-surface items to stop pooling of liquids and liquid ingress. Also, as its positioning is independent of any below work-surface items, it is easy to fit the liquid director with minimum disruption, and the positioning is not affected by the front profile of the work-surface.

Preferably, the liquid director is adhesively attached via its upper mounting surface, so as to provide a secure and easy installation.

The liquid director can extend parallel to a longitudinal edge of the work-surface. It can be of an equal length to the longitudinal edge of the work-surface. As it is attached along the entire length of the longitudinal edge, this ensures that there are no gaps for liquids to penetrate. The liquid director of the first or second aspect can be made of a flexible, advantageously resilient material such as silicone rubber. The liquid director can be made of an anti-microbial silicone rubber. The liquid director can also be made from, at least partially, PVC, preferably TE Grade PVC.

Alternatively, the liquid director can be made from a combination of both.

An anti-microbial silicone rubber will inhibit bacterial growth such as MRSA and is advantageous for use in an environment such as a kitchen. The properties of TF Grade PVCare preferred for the second aspect of the present invention where it is desirable to be able to knock in' the upper mounting portion of the director into a recess.

The profile of the first or second aspect may comprise two projections extending generally downwardly to further enhance the effectiveness of the liquid management.

Preferably, the at least one projection of the first or second aspect is located at a position laterally doser to a front longitudinal edge of the work-surface than the worktop item, so as to deflect spilled water away from the worktop item.

The worktop may comprise a non-water-resistant core such as chip board or MDE covered by a layer of water-resistant material such as a melamine laminate or a treated paper or a plastics material.

The liquid director of the second aspect advantageously does not interrupt or divert the layer of water resistant material. This means that the manufacturing process for the work surface does not need to be changed, and the installation of the liquid director is simple.

There may be a join in the water resistant material on the underside of the work-surface, substantially parallel to the front edge, and a front edge of the liquid director is preferably located forward of the join. Such joins represent an area of potential water ingress to the core, so mounting the director forward of this location, helps to protect the core. The liquid director may advantageously overlie the join to further protect it.

A third aspect of the invention provides an elongate liquid director for mounting to an underside of a work-surface to inhibit the unwanted flow of liquid behind the liquid director, the liquid director having a substantially constant profile along its length.

said profile comprising a mounting portion having a substantially planar face for mounting to the work surface, and two projections extending generally downwardly therefrom, so as to divert the liquid flow.

The liquid director may be adhesively attached to an underside face of a work-surface.

It can be fixed directly to a bottom face of the work-surface, preferably located in a position forward of any below work-surface items. It does not rely on being mounted between the work-surface and any bdow work-surface items. This means therefore, that it is applicaNe to a range of different types of work-surface and below work-surface configurations.

The liquid director may comprise at least one projection that tapers to a point. This helps to ensure that the liquid is directed in the preferred downwards direction.

Preferably, the Uquid director can comprise two projections that taper to a point.

The liquid director may comprise at least one projection with at least one curved edge.

The actua' profile can vary between embodiments so that the curved edge may provide a concave surface as a front face of the liquid director but may also provide a convex surface as a front face of the liquid director, a concave surface as a second face of the liquid director, or a convex surface as a second face of the liquid director.

A curved edge is ideal for directing liquids, as gravity and surface tension effects cause liquids to follow the path of the surface and be directed away from the below The liquid director can be made from a flexible, preferably resilient material such as a silicone rubber matenal, preferably an anti-microbial silicone rubber, or PVC, preferably TF Grade PVC, or a combination of both.

The liquid director can have an adhesive layer covered by a removal backing provided on the mounting portion.

A fourth aspect of the invention provides an elongate liquid director for mounting to an underside of a work-surface to inhibit the unwanted flow of liquid behind the liquid director, the liquid director having a substantially constant profile along its length, said profile comprising a mounting portion having a resilient formation for mounting to a recess in the work surface, said profile comprising at least one projection to direct the liquid flow. At least one projection can taper to a point.

A fifth aspect of the invention provides an elongate liquid director for mounting to an underside of a work-surface to inhibit the unwanted flow of liquid behind the liquid director, the liquid director having a substantially constant profile along its length, said profile comprising a mounting portion having a substantially planar face for mounting to the work surface, said profile comprising at least one projection, wherein said projection tapers to a point The liquid director of the fourth aspect and the liquid director of the fifth aspect may optionally incorporate features of the third aspect of the present invention.

DETAILED DESCRIPTION OF EMBODIMENT(S)

Figures 1 and 2 show a worktop 10, comprising a work-surface 12 and below work-surface item 14. The work-surface 12 has a top face l2a, front face 12b and bottom face 12c. Between top face i2a and front face 12b is a curved transition 16, and between front face I 2b and bottom face I 2c is a curved transition 18.

In this embodiment, below work-surface item 14 is a drawer 20 with top face 20a, front face 20b and back face 20c.

In use, as shown in figure 2, liquids run off the work-surface top face 12a. around the curved transition 16, down the front face 12b, around the curved transition 18 and along the bottom face 12c. From there, liquids meet the drawer 20 and can follow three potential routes; straight down the front face 20b, along the top face 20a and then down the back face 20c; or continuing further along the bottom face to the rear.

Figures 3 and 4 show the worktop 10, comprising the work-surface 12, a recess 13 in the work-surface, the below work-surface item 14, and a liquid director 22 according to a first embodiment of the present invention. In profile, the liquid director has an upper mounting portion 23, to be mounted in the recess 13 of the work-surface bottom face 12c (e.g. sealant such as silicone sealant is injected into the recess 13 and the mounting formation is then pushed in). The combination of sealant and the mounting portion 23, securely anchor the liquid director in place and reduce water ingress into the core of the worktop 10.

In this embodiment, the recess 13 extends as a continuous groove running longitudinally along the bottom face 12c of the work surface (e.g. formed by a router) but in other embodiments could consist of discrete recesses (e.g. formed by a drill) rather than a continuous recess.

The upper mounting portion 23 comprises a bottom section 36 of a substantially similar width as the recess 13 in the work-surface 14, connected to a thinner vertical limb 38, and fingers 40 extending outwardly from the vertical limb 38. The upper mounting portion 23 is symmetrical such that only the front half of the profile is described below, but the rear half of the upper mounting portion 23 can be assumed to have the same profile but mirrored.

Considering the front profile of the upper mounting portion 23 starting at the lowest point, a flat vertical face of the bottom section 36a intersects the front top surface section 22a. The flat vertical face 36a is connected to a flat horizontal face 36c by a curved transition 36b. A further curved transition 36d connects the flat horizontal face 36c to the vertical limb 38.

The vertical Umb 38 has six fingers 40 protruding outwardly, three fingers protruding out of the front face of the vertical limb 38 and three fingers protruding out of the back face of the vertical limb 38. The fingers are arranged to protrude outwardly as well as downwardly such that the profile of the vertical limb 38 combined with the fingers 40 resembles a "Christmas tree" shape. A first finger 40 comprises a flat lower face 40a on its bottom surface and a flat upper face 40c on its top surface, connected to each other by a curved transition 40b. The flat faces 40a and 40c are at the same angle to the vertical, pointing generally downwards, such that each finger 40 has a consistent width. Each finger 40 has the same profile. The upper faces 40c of the two highest fingers 40, on the front and back of the mounting portion intersect each other to create a top point 42 of the mounting portion 23.

The top point 42 defines the axial centre point of the mounting portion 23, such that a line of symmetry of the mounting portion 23 passes vertically through this point.

When the front half of the profile of the mounting portion 23 is mñTored in this line of symmetry. the overall profile of the entire mounting portion is provided.

The liquid director 22 further comprises a generally downwards tapering projection 24a. The projection 24a has a general front surface 26, compnsing a flat section 26a angled at approx 18° to the vertical which intersects the front top surface 22a, and at its lower edge meets a convex curved transition 26b. This curved transition meets a curved surface 26c at its lower edge then transitions into a fiat front face 26d angled at approx. 23° to the vertical. The front face 26d terminates in a pointed tip 32. A second fiat face 28e angled at approx. 41° to the vertical is part of a general back surface 28 and intersects front face 26 at the tip 32.

The back surface 28 further comprises a flat section 28a which is substantially vertical and meets the back top surface 22b at its upper edge. A curved transition 28b connects section 28a with a substantially horizontal section 28c. Section 28c is connected to a flat face 28e by a concave curved transition 28d.

The front top surface section 22a and the back top surface section 22b are both angled slightly upwardly, so that in use the edges defined by the intersection of surfaces 22a and 26a and 22b and 28b respectively are urged into contact with the bottom surface l2c of the worktop a to create an enhanced seal as best seen in figure 7. It will be appreciated though, that surfaces 22a and 22b are in reality deflected downwardly from the position illustrated in Figure 7.

Installation of the liquid director 22, either during manufacture of a work-surface 12, or as a retrofit on an existing worktop is a straightforward operation. In the case of a retrofit, the recess 13 needs to be created. This is simple to do; a groove can be easily created on site using an appropriate tool (eg. a router). The mounting portion 23 is inserted into the recess 13, and the formation is dimensioned such that during insertion into the recess 13 the formation is alTanged to compress, in order to increase the ease of insertion. It is then securely held in place by the protrusions in order to not fail out again dunng use.

FigureS illustrates the uniform profile of liquid director 22 along its length.

In use, as shown in figure 4, liquids run off the work-surface top face 12a, around the curved transition 16, down the front face 12b, around the curved transition 18 and along the bottom face 12c. With the liquid director 22 installed, liquids come into contact with the front surface 26 of the liquid director 22 and are directed downwards, reducing the chance that any liquids will make it into the gap between the work-surface 12 and the below work-surface item 14.

The liquid director 22 of this embodiment is made from a flexible, resilient material; in this embodiment TF Grade PVC. In one embodiment it is manufactured by extruding PVC through a suitaNy shaped tool die.

Figure 7 illustrates how the profile of the mounting portion 23 of the liquid director 22 enables it to remain securely in place within a recess 13 of the work-surface 12. The fingers 40 extending from the vertical limb 38 engage the inner surfaces of the recess 13, holding the liquid director 22 in place. It will be appreciated that the fingers 40 are shown in their non-deflected state, and that, in reality, when inserted will flex downwardly as they bear against the recess 13.

The recess 13 has a mouth 13a, proximate to the bottom face of the work-surface l2c.

The angle of the fingers 40 is such that they point generally more in the direction of the mouth l3a, resuhing in the Uquid director 22 being rdatively easy to insert but difficult to then pull out again. In addition, the entire mounting portion 23 is resilient and flexible such that in use, the fingers 40 can compress inwardly to make insertion straightforward.

Further, the bottom section 36 of the mounting portion 23 is substantially the same width as the recess mouth 13a, creating a good seal after insertion to prevent liquid and dirt ingress.

Figures 8 and 9 show the worktop 10, comprising the work-surface 12. the below work-surface item 14 and a liquid director 22' according to another embodiment of the present invention. In profile, the liquid director has a upper mounting surface 22a', providing an area to be adhesively attached to the work-surface bottom face 12c (e.g. by an adhesive supplied thereon, and covered until installation by a removable backing tape (not shown). The liquid director 22' comprises two generally downwards tapering projections 24a' and 24b', both of which are similar in cross-section.

More specifically the liquid director 22' comprises a front projection 24a' and back projection 24b'. Front projection 24a' has a general front surface 26', comprising a flat section 26a' angled at approx 18° to the vertical which intersects the top surface 22a', and at its lower edge meets a curved section 26b'. The curved surface 26b' then transitions into a flat front face 26c' angled at approx. 23° to the vertical. The front face 26c' terminates in a pointed tip 32'. A second fiat face 30a' an&ed at approx. 410 to the vertical forms a rear face 30a' of the front projection 24a', as part of an inner surface 30' and intersects front face 26' at the tip 32'.

Back projection 24b' has in this embodiment a back surface 28', comprising a flat section 28a' which is substantially vertical and meets top surface 22a' at its upper edge. A small horizontal portion 28b' connects section 28a' with a further flat face 28c' forming the rear of the back projection 24b' and also ang'ed at 41° to the vertical.

A tip 34' forms the intersection of rear flat face 28c' and a front flat face 30c', which is angled at 23° to the vertical. The inner surface 30' is completed by a curved surface 30b', having the same radius as curved surface 26b', but a greater circumference, and which connects faces 30a' and 30c'.

In this embodiment the liquid director has a front to rear depth of approx 12mm and a vertical height of approx 7mm. As such, it can be appreciated that it is relatively compact and unobtrusive in use.

Installation of the liquid director 22', either during manufacture of a worksurface 12, or as a retrofit on an existing worktop is a straightforward operation. The removable backing tape is removed from the upper surface 22a', revealing the adhesive, and the liquid director is adhered to the underside of the work-surface 12 at a location where the tip 34' of at least the front, but preferably the back projection is forward of the under work-surface item 14 (e.g. drawer 20), and the front is behind the curved transition 18. Additionally, the liquid director 22' may be installed, as shown in Figure 9, so as to overlie a join 15 in the water resistant covering 17 on the surface of the work-surface 12.

Figure 10 illustrates how the profile of liquid director 22' stays constant along its entire length.

In use, as shown in figure 9, liquids run off the work-surface top face 12a, around the curved transition 16, down the front face 12b, around the curved transition 18 and along the bottom face 12c. With the liquid director 22' installed, liquids come into contact with the front surface 26' of the liquid director 22' and are directed downwards. Any liquids that make it past the front surface 26' will come into contact with the inner surface 30' and then be directed downwards, reducing the chance that any liquids will make it into the gap between the work-surface 12 and the below The liquid director 22' is made from a silicone based material, preferably all anti-microbial silicone rubber. In one embodiment it is manufactured by extruding a silicone Hank through a purpose made tool die.

Although the invention has been described above with reference to one or more preferred embodiments, it will be appreciated that various changes or modifications may be made without departing from the scope of the invention as defined in the appended claims.

This especially applies to the profile of the liquid director, which can be shaped in a variety of further ways yet still satisfy the requirement of causing liquid to run off in a downward direction, as desired.

For example, the profile of the liquid director 22 could be changed by varying the number of projections, which edges are curved or fiat, whether surfaces are convex or concave, and any other suitable modifications.

It will further be appreciated that various alternative formats of mounting portion may be utilised in the liquid director of the first embodiment. E.g. finger may only project from one side of the limb, and the number of fingers may be increased or decreased.

The shape of the fingers may be altered -e.g. be curved, or be semicircular to connect to the limb in two locations.

In the present embodiment a sufficient clearance is illustrated between the liquid director 22 and the top of the below work surface item. However, in other embodiments, the liquid director may be sufficiently flexible so as to deflect out of the way as the below work surface item is opened.
