Description

[0001] Tap

[0002] Field of The Invention

[0003] The invention relates generally to the field of taps, faucets, tap or faucet devices, hose tap connections and outdoor water activities, particularly for use with water play toys, taps and / or faucets. More specifically, the invention relates to water play toys, attachments for taps and / or faucets for children.

[0004] Background

[0005] Water taps or faucets are essential fixtures in both residential and commercial settings, providing a convenient means of accessing water for various purposes. Such water taps and faucets, are found both inside and outside a home, including in kitchens, bathrooms and gardens. Traditional water taps may be difficult to turn on and off, especially for children or people with hand weakness, such as the elderly.

[0006] Standard water taps or faucets are often not designed with children in mind. The water pressure can be difficult for children to manage, leading to potential safety hazards and excessive water flow. Additionally, the twisting required to use traditional water taps and faucets can be difficult for children, particularly young children, who may struggle to turn taps on and off completely due to having less strength and motor skills. This can lead to water wastage when taps are not fully turned off. However, children love to play with water, they enjoy how it moves, comes out of taps and enjoy filling containers. There are many water play toys in the current market, including water tables, slides, sprinklers, water blasters, super soakers, paddling pools and pool toys. However many of these require cleaning and refilling as well as take up a lot of space and / or require close adult supervision, especially in scenarios with large bodies of water, such as bathtubs or pools, there is a risk of drowning, particularly for young children who require constant supervision.

[0007] Outdoor taps are commonly used for gardening, car washing, sprinklers and other external activities. These taps are frequently left on unintentionally, leading to significant water wastage and increased risk of flooding. Additionally, hoses and their attachments may be left on by children and can be used to spray adults, other children or areas not intended to get wet. Furthermore, resulting puddles or large containers filled with water, such as pools, may also pose a drowning risk to young children. It would be useful to have user-friendly tap devices that allow users to safely access water, are easy to operate and / or prevent water wastage. Furthermore, there is a need for child-friendly taps or devices that regulate water pressure, are easy for children to operate independently, reducing the need for constant adult supervision and / or minimise the risk of water-related accidents.

[0090] Description of Preferred Aspects of the Invention

[0091] Taps and faucets are used both indoors and outdoors, traditionally these are turned on and off using a rotating handle mechanism. There are also many taps that include a lift handle that is designed to be lifted to allow water to flow. Household outdoor taps commonly have a rotating handle for turning the tap on and off. Such outdoor taps generally include a spout or spigot having a threaded end to allow attachments such as a hose to be connected to the tap.

[0092] The tap device 10 of the current invention is described here in further detail with respect to Figures 1 - 14b. The tap device 10 of the invention is generally configured to couple or attach to a tap, faucet or other plumbed water source 50 to increase ease of use and / or prevent water wastage. Figures la to 3 show a first embodiment of a tap device 10 coupled to a plumbed tap 50. A connector 16 is shown to couple the tap device 10 via an inlet tube 32 to the plumbed tap 50 (see Figure lb). In this form the connector 16 includes an internal thread 17 configured to allow direct screw attachment of the connector 16 to a threaded spout of a plumbed tap 50. A range of different sized threaded connectors 16 may be available to accommodate different tap diameters. In one form, the connector 16 is a bayonet connection which requires a push-and- twist motion for disconnection from the plumbed water source 50. A push-and-twist motion for disconnection provides additional safety for the user, in particular when the device 10 is in use during play for a child, as disconnection requires advanced coordination. Further safety is provided by the connector 16 through at least this bayonet connection. An increased difficulty associated with the disconnection from the plumbed water source 50 reduces the chances that the device 10 is accidentally disconnected which may expose or dislodge any internal elements of the device 10. Internal elements may be dangerous to the user, either as a small choking hazard or as a sharp piece.

[0093] Alternatively, the tap device 10 may be coupled to the plumbed tap 50 via other known hose or tap connection systems such as bayonet, push and click, clamped or snap fit type connection (not shown). In other forms, the tap device 10 may be configured to be coupled to a stand and / or be connected via a section of hose or other adapter. In further forms, the tap device 10 may be configured to connect to plumbed taps, faucets and shower heads for indoor use. However, such use may require an adaptor to allow the connection.

[0094] The tap device 10 as shown comprises an outer casing. In one embodiment, the outer casing is formed of two parts, a front outer casing 11 and back outer casing 12 that are coupled together to surround an internal housing 20. The internal housing 20 includes a body portion 20b and a lid portion 201 that are fastened together and protect the flow control assembly elements of the tap device 10. The lid portion 201 of the internal housing 20 is coupled to an actuation mechanism 13 that is configured to be actuated by a user and that is configured to control the flow of water or fluid through an outlet 14 in the internal housing 20. The actuation mechanism 13 is preferably configured to be simple / easy to actuate for users such as the elderly, children, people with hand weakness or other disabilities, or animals / pets, which is described in further detail below. The user can also be considered to be an adult or other type of user as reasonable. The outer casing can be made of a durable material to protect the internal components from damage and environmental factors. Preferably the front outer casing 11 and back outer casing 12 form the outer casing and together either partially, significantly, or entirely enclose the internal housing 20 or flow control assembly or chamber and its components. The outer casing enclosing the internal housing 20 helps prevent access to small parts that may cause injury or jamming to the user, for example reducing children or pets pinching fingers, noses, or otherwise, during play. Preferably the front outer casing 11 and / or back outer casing 12 are formed with some or all of the surfaces being smooth internal and / or external surfaces to improve safe user interaction with the device 10 by further reducing chances of injury such as pokes or cuts during play or when not in use.

[0095] Various connectors 16 may also be used to increase safety for the user of the device 10. Connectors 16 such as those shown in figures 13a and 13b include reduced external features which can assist with further reducing pinching or scraping of fingers, or otherwise, during play or when not in use.

[0096] In some forms, the front outer casing 11 may optionally comprise aesthetic features 30 that provide appeal to certain users, particularly children. As shown the outer front casing 11 may include animal face features such as a mouth, snout, eyes, ears or similar, for example, a hippopotamus face (see Figures la and lb), bear face (see figures 4a and 4b) or any other type of face, or other surface design or features. In such forms, the outlet can be located adjacent a mouth area of the decorative face. In other forms the front outer casing 11 may be a plain surface without any aesthetic features.

[0097] Having the front outer casing 11 formed as a separate component provides the advantage that it is interchangeable with other versions, for example to provide a different surface design or face. However, it is appreciated that in alternative forms the front outer casing 11 and back outer casing 12 may be integrated into a single component (no shown).

[0098] Figures 2a, 2b, 3, 5a and 5b show a sub-assembly of the tap device 10 with the front outer casing 11 and back outer casing 12 removed. As shown the internal body 20 is coupled to the actuation mechanism 13, and in this embodiment the actuation mechanism provides a lever. The actuation mechanism 13 includes a mounting portion 19 configured to engage with a moveable component of the control flow assembly housed in the internal body 20 to open and close access to the outlet 14. The flow control assembly 28 is explained in more detail below.

[0099] The actuation mechanism or lever 13 is constructed to move between closing and opening fluid access to the outlet 14. The outlet 14 is preferably formed at an end of the internal housing 20 and is biased in a closed position to prevent water or other fluids from flowing therethrough. The actuation mechanism or lever 13 is configured to move between a closed position and an open position, with the closed position being the default or biased position. In the open position water is allowed to flow through the outlet 14. In one embodiment, the actuation mechanism 13 requires a push movement to move from the closed position to the open position. However, it is to be understood that the actuation mechanism may also be a pull movement or a rotational movement. In some forms, stops may also be provided to prevent the actuation mechanism 13 from moving to far in forward or backwards (not shown). The activation mechanism may also be in the form of a button rather than a lever.

[0100] In a preferred arrangement it has been found that a push movement, such as a push lever, is easy for users such as young children, pets, or other user to activate. In such embodiments, the lever's length must be sufficient to allow a user to activate the lever. Preferably the lever has a length of at least 3 cm, preferably between 3-20 cm in length, more preferably between 5- 15cm, or 8-10 cm. In alternative uses, such as for a pet, the lever may be longer that 20 cm to allow a pet to easily nudge the lever. Manual activation of the lever with a bias to return to the closed position assists with reducing water waste during use.

[0101] In certain embodiments the actuation mechanism 13 is a curved lever to provide increased strength and / or ease of use. Preferably the curvature is designed to accommodate a variety of vessel shapes that may be pushed against the lever.

[0102] The internal housing 20 comprises a flow control assembly configured to control the fluid flow through the tap device 10 to the outlet 14 and will now be described in more detail below. As mentioned above, the internal housing 20 comprises the housing body 20b and the housing lid 201. The housing lid 201 is fastened to the housing body 20b by any fastening means including via a screwed thread as seen in figures 5b, 7a, 7b and 10 or via a snap fit or bayonet type connection as seen in Figure 5a. Other known fastening means may be used.

[0103] In the illustrated embodiment, the housing body 20b comprises an inlet body portion 38 and an outlet body portion 40 (see figures 8b and 9b). The inlet body portion 38 comprises a housing inlet 15 and is configured to seal ingly couple to the inlet tube 32 to receive the water within the housing body 20. The outlet body portion 40 comprises a flow control assembly 28 configured to receive the water delivered through the inlet tube 32 and control or reduce the pressure and / or flow rate of the water for delivery to the outlet 14. In a preferred embodiment the flow control assembly comprises a diaphragm 22 having a spring 24 that is coupled to a piston 26. The piston 26 comprises an attachment portion 26P at an upper end configured to engage with a piston cap 54 of the actuator mechanism 13. The opposing end of the piston 26 comprises tip or plunger portion 26T that is configured to act against the diaphragm. In one form the attachment portion 26P comprises one or more lugs or pins to couple with complementary receiving portions in the piston cap 54, forming a locking mechanism 19. More detail on the flow control assembly 28 is provided below.

[0104] The tap device 10 may be sealing coupled to the connector 16 via the inlet tube 32. In this arrangement a first end of the inlet tube 32 is connected to the connector 16 and the opposing end is connected to the inlet body portion 38 of internal housing body 20b. The inlet tube 32 comprises a seal or O-ring 64 to ensure the engagement with the inlet body portion 38 is water tight. An engaging clip 36, or other form of connector, is configured to retain the inlet tube 32 in engagement with the inlet body portion 38 in use. The clip 36 may be in the form of a horse shoe clip 36 as seen in Figure 8b. Such a clip slides over and locks into place on the inlet body portion 38 securely clamping the two components together forming an inlet section. The use of such a clip 36 allows for ease of removal and attachment of inlet tube 32. This may facilitate attachment to a range of plumbed water sources 50 during assembly, including to other types of faucets and shower heads to accommodate indoor use. Thus, having inlet tubes 32 of different sizes and configurations such as in a straight configuration (shown in figures 11a and lib) provide for attachment to a range of water sources or attachment systems such as a stand, hose or other water connection system. In some forms the inlet tube 32 may be required to couple to another adaptor to allow the connection to the plumbed water source 50. In other embodiments the inlet tube 32 may be configured to directly couple to the plumbed tap 50. The inlet tube 32 can be configured to include comprise various attachment features such as a wall bracket 51 for connection / stabilising of the inlet tube 32 (shown in figure 12).

[0105] In some embodiments the inlet tube 32 may be angled to align the tap device 10 in a preferred position relative to the spout of the plumbed tap 50. In an embodiment designed for attachment to an outdoor plumbed tap 50, the inlet tube 32 may comprise a 25 to 45 degree bend, preferably 30 degree bend, to align the tap device outlet at a substantially vertical or normal or 90 degrees position relative to the ground for ease of operation. A mesh ring 62 to reduce debris entering the tap device 10 may be located upstream or adjacent to the housing inlet 15. The mesh ring 62 is preferably provided within the connector 16, or the inlet tube 32 or at the housing inlet 15 of the inlet body portion 38 of the internal housing. The connector 16 may also include a flow regulator 66 to reduce the overall flow and / or pressure through the device. The flow regulator 66 may include a flow regulating washer, a flow regulating valve or pressure reducing valve. It will also be appreciated that the flow regulator 66 may be provided anywhere within the fluid flow path between plumbed water source 50 and the outlet 14. For example the flow regulator 66 may be located within the connector 16 (see figure 5b), if used, the inlet tube 32, or within the internal housing 20 or adjacent the outlet 14 (see figure 10). Preferably the flow regulator 66 is positioned in advance of the inlet 15 to inlet body 38 to reduce overall flow and effectiveness throughout the flow control assembly 28. This position may also help reduce back pressure within the internal body 20.

[0106] In some forms a plurality of flow regulators 66 may be installed within the fluid flow path. In a non-limiting example, a flow regulator 66 may be located at or adjacent the inlet 15 and / or in the connector 16 and a further flow regulator 66 may be located at or adjacent the outlet 14 (see figure 11a).

[0107] Different sized flow regulators 66 or pressure reducing valves may be used to reduce the water flow through the trap device 10. There are a range of commercially available flow or pressure regulator valves that are commonly used within many internal faucets or garden watering systems. For example, Neoperl™ manufacture a range of water saving flow regulators that may be used. The specific flow regulator to use will depend on the desired flow rate in litres per minute (Ipm) required at the outlet 14 and the specific application.

[0108] Garden taps commonly have a flow rate in the range of 10 to 15 litres per minute and internal household taps commonly have a flow rate in the range of 6 to 12 litres per minute. The desired flow rate of the fluid or water exiting the outlet 14 may be between 2 litres per minute (Ipm) and 18 Ipm, preferably less than 10 Ipm, such as between 2 Ipm and 8 Ipm or between 3 Ipm and 6 Ipm. For a children's toy, the preferred range would be between 2 Ipm and 5 Ipm, and when used for small children most preferably 31pm or 41pm. For other applications such as an adult garden version it would be preferable to use a flow rate in the higher range, such 5 Ipm to 12 Ipm. A range of between 2 Ipm and 5 Ipm provides a safe flow rate for children or pets to interact with the device 10. Compensating the pressure and / or flow via for example regulator 66 can also reduce unpredictable bursts of water and / or unpredictable high flow rates, of which can be dangerous for children or pets interacting with the device 10 or can be simply intimidating and cause the user to be hesitant to interact with the device 10.

[0109] The flow regulator 66 is generally used to provide a more controlled flow and reduce intense splashing as the water exits the outlet 14. In some forms an aerator film material 72 may also be used in addition to the flow regulator 66. The aerator film material 72 is preferably positioned before the water exits the outlet 14 as seen in figure 10). Figure 6a shows a subassembly of the connector 16 attached to the inlet tube 32 and the inlet body 38 of the internal housing body 20b. The piston 26 is positioned within the internal housing body 20 with the piston attachment portion 26P extending through an aperture in the internal housing lid 201. The piston attachment portion 26P engages with the mounting portion 19 on the actuation mechanism 13 in use. When engaged movement of the actuation mechanism 13 causes the piston 26 to move upwards within the internal housing body 20 allowing access for fluid or water to flow through the outlet 14. Preferably one or more locking guides 52 are formed in the housing lid 201 and are configured to engage with one or more guides 34 provided on the actuation mechanism 13 (see Figures 6b) to support the engagement of internal housing 20 with the actuation mechanism 13. As shown in the embodiment the guides 34 and locking guides 52 are in the form of ribs that may substantially align or interlock when the actuation mechanism 13 and internal housing 20 are coupled together. The guides 34 and locking guides 52 are arranged to prevent the actuation mechanism 13 from twisting or turning when moved between the open position and closed position in use. The guides 34 are located on either side of the mounting portion 19 of the actuation mechanism 13 such that when the piston attachment portion 26P is inserted into the mounting portion 19 the guides 34 engage with the locking guides 52 on the internal housing lid 201. It is to be understood the guides 34 and / or locking guides 52 may take other forms to prevent the actuation mechanism 13 from twisting and turning.

[0110] Figures 3 and 10 show embodiments of the flow control assembly 28. The flow control assembly 28 includes a diaphragm 22, a spring 24 and the piston 26. The spring 22 is positioned around the piston 26 and these are inserted into the diaphragm 22 with the piston tip 26T positioned and engaged with the base of the diaphragm 22, forming a diaphragm assembly. As seen in Figure 3, the piston tip 26T may be formed as a plunger with piston tip 26T inserted into formed pocket or recess in the based on the diaphragm 22 to securely engage the piston 26 with the diaphragm. In an alternative form, as seen in figures 7a, 7b and 10 the piston tip 26T may have a shaped tip that engages with a recess or pocket in the diaphragm 22 to ensure the diaphragm 22 can move in coordination with the piston 26. The diaphragm 22 is made of a deformable elastic material such as silicone or any other flexible elastic material such as a thermoplastic elastomer (TPE).

[0111] The diaphragm assembly is inserted into the outlet body 40 of the internal housing body 20b and positioned to be seated against an outlet lip 76 surrounding an opening in the outlet body 40. When the piston attachment portion 26P is engaged with the piston cap 54 the diaphragm assembly is configured to move up and down within the outlet body 40 when the actuation mechanism or lever 13 is moved. In the default closed position the diaphragm assembly is positioned against the outlet lip 76 to prevent fluid or water 70 flow through the outlet 14. In the closed position spring 24 is configured to bias or push the piston 26 with the engaged diaphragm 22 against the outlet lip 76. When the actuator mechanism 13 is pushed backwards the piston 26 is pulled upwards compressing the spring 24 and lifting the diaphragm assembly away from the outlet lip 76 to allow fluid to flow therethrough. The fluid or water 70 flows through the opening in the outlet body 40 to the outlet 14.

[0112] In some forms a flow regulator 66 is positioned between the opening in the outlet body and the outlet 14 to ensure a safe and manageable flow of water 70 exits through the outlet 14 for the specific user. The flow regulator also facilitates the use of a softer spring 24 to ensure the actuation mechanism or lever 13 remains easy and light to press, requiring minimal effort / force and offering smooth operation for even very young children. Spring 24 may be selected for appropriate use in device 10. Preferably, spring 24 has a small wire thickness, such as a 1mm wire thickness, to provide ease of compressing, resulting in the actuation mechanism or lever 13 requiring minimal effort / force. Other wire thicknesses may be used for spring 24 such as 2mm, 3mm, 4mm, or otherwise. Spring 24 can also include tapering from a small end to a large end. Example tapering of spring 24 may include a 7.5mm inner diameter at the small end to a 11.33mm outer diameter at the large end. Tapering of the spring may also provide ease of compressing, resulting in the actuation mechanism or lever 13 requiring minimal effort / force. Other means can also be taken to provide an ease of compressing the spring 24 including control of the number of coils in the spring and the total length. An example spring may be 27mm in length with 5 coils. Configuration of spring 24 acts to balance two needs of the spring, being that the spring 24 is strong enough to maintain a reliable seal against water pressure while remaining soft and easy to compress, allowing even an 18-month-old child to push it comfortably. The tapered design provides gentle initial resistance that progressively increases to ensure effective sealing without excessive force.

[0113] In other forms a stronger spring may be used in conjunction with higher litre per minute flow rates such as for use by adults. Although both provide advantages individually, the lever 13 requiring minimal effort / force in combination with control of the flow and / or pressure via the flow regulator 66 or pressure reducing valve provides for a simple and safe combination for users such as children or pets.

[0114] The diameter of the outlet 14 may vary depending on the proposed use and size of the tap device 10. The outlet diameter may be in the range of 3 mm to 50 mm in diameter, preferably between 5mm to about 30mm, more preferably less that 10mm, such as 9mm. The outlet cap 46 may also come in a variety of different forms and be removably attached to the outlet 14 to adjust the flow patterns of the flow of water exiting through the outlet 14. For example the outlet cap 46 may comprise a single aperture, a shower type head, a long spout or nozzle or multiple nozzles to facilitate filling of different toys or vessels such as water balloons or water guns.

[0115] A preferred embodiment of the tap device 10, 110 assembly will be described with reference to figures 2a, 2b, 5a, 5b, 7a and 7b. In an initial step the diaphragm assembly is assembled by connecting the piston 26, spring 24 and diaphragm 22. The diaphragm assembly is inserted into the outlet body 40. The internal housing 20 is connected to the actuation mechanism 13 by inserting the inlet body 38 through the aperture 78 in the actuation mechanism 13 so that the inlet body 38 with inlet 15 extend through the aperture 78. The piston 26 is engaged with the actuation mechanism 13 by inserting and securing the attachment portion 26P within the piston cap 54 and engaging the lid guide 34 with the locking guides 52 on the actuation mechanism 13. The piston attachment portion 26P and piston cap 54 form a locking mechanism 19 that secures the piston 26 to the actuation mechanism 13 and is arranged to allow the actuation mechanism in the form of a lever 13 in the shown embodiment to pivot.

[0116] The back outer casing 12 is coupled to the internal housing 20 by inserting the end of inlet body 38 of the assembled internal housing 20 and actuation mechanism 13 through the housing aperture 48 and engaging clip supports 18 on the internal housing 20 with clip apertures 56 on the back outer casing 12. As shown the lower clip support comprises an attachment lip 18a to engage in a snap fit with the lower clip aperture 56 in the back outer cover 12.

[0117] Next, a mesh ring 62, rubber washer 68, and optionally a flow regulator 66, are inserted into the connector 16 prior to the connector 16 being sea lingly coupled to a first end of the inlet tube 32. The inlet tube 32 is inserted through an aperture in the connector 16 between the mesh ring 62 and rubber washer 68 and optional flow regulator 66. In the illustrated embodiment the first end of the inlet tube 32 and connector 16 are engaged via a threaded connection 17 but it will be appreciated that other connection mean may be used as described above. An opposing end of the inlet tube 32 with an attached O-ring are inserted into sealing engagement with the inlet 15 in the inlet body 38. Clip 36 is inserted around the end of the inlet body 38 adjacent the inlet 15 to clamp the inlet tube 32 in position. In the illustrated embodiment the clip 36 is a horseshoe shaped clip but any other clamping or fastening means may be used or the inlet tube 32 may be directly fastened to the inlet 15 via other means such as a threaded connection (not shown). An outlet cap 46 is attached to the second end of the outlet body 40. Finally, the front outer casing 11, 111 is attached to the back outer casing 12 via a clipping mechanism. For example the back outer cover includes an internal lip region 58 having a plurality of slots 60 that are configured to receive lugs (not shown) formed in an internal rim of the front casing 11, 111. The back outer casing and front outer casing arranged to cover and protect the internal housing 20.

[0118] It is to be understood that the other attachment systems may be used to connect the different components to those described above without departing from the inventive concept. Such as using rivets, clamping, screwing or other mechanical fastening.

[0119] To understand the operation of the tap device 10 refer to figures 3 and 10. The tap device 10 is securely connected to a water source 50 such as a household tap via the connector 16 and / or inlet tube 32 or via any other type of connection. When the water source 50 is turned on to allow water to flow the water 70 flows through the inlet tube passing through the mesh ring 62 to prevent blockages occurring within the tap device 10. If using, the water then flows through a flow regulator 66 to decrease the water pressure and flow rate entering the inlet 15 of the internal housing 20. Water 70 is prevented from exiting the outlet 14 in the default close position as the piston 26 biases the diaphragm 22 via the spring 24 to sealingly close against the outlet lip 76. When a user moves, preferably pushes, the actuation mechanism 13 to the open position the piston is moved upwards and the spring 24 compresses together pulling up the diaphragm 22 from the outlet lip 76 allowing water to flow through to the outlet 14 and through the outlet cap 46. When released the actuation mechanism 13 will return to the biased closed position. Generally the piston 26, spring 24 and diaphragm 22 are designed to handle pressures up to 500 kPa in the closed position to prevent water flowing through the outlet 14.

[0120] Many of the components of the tap device 10 including the front outer casing 11, back outer casing 12, internal housing 20 and inlet tube 32, are preferably formed by moulding. Such components may be made from one or more of polyethylene (such as LLDPE, LDPE, MDPE, HDPE), polycarbonate (PC), Polypropeylene (PP), Acrylonitrile Butadiene Styrene (ABS), Acetal(POM), Acrylonitrile Styrene Acrylate(ASA), Nylon(PA6, PA12, PA66), Polyethylene Terephthalate(PET), Polylactic Acid(PLA), Polyhydroxyalkanoates(PHA), Polypheneylene Sulfide (PPS), Polyphenylsulfone(PPSU) or any other similar moulding plastic materials or combinations thereof.

[0121] While the description has primarily focused on the tap device as a children's water toy it is to be appreciated that the tap device may be used by others and / or for other purposes. For example, as a convenient easy to use tap for anyone. Those skilled in the art will appreciate that the tap device may also be configured with a different actuation mechanism such as longer lever to allow a pet, such as a dog, to activate the water flow.
