Description

Field of the Invention

[0001] The present invention relates to a cleaning apparatus comprising at least one open mouth container capable of receiving a volume of fluid; and at least one magnet attachable to said open mouth container to entrap magnetic materials, removing them from said volume of fluid. Background of the Invention

[0002] Cleaning apparatus comprising at least one open mouth container capable of receiving a volume of fluid e.g. a bucket, are used to contain water for washing a variety of surfaces including inter alia: floors, windows, cars, patio furniture, caravans, vehicles, mobiles homes.

[0003] For surfaces where an aesthetically pleasing finish is required, grit and dirt particles can prove challenging, often scratching the surface being cleaned during the washing process. For car washing enthusiasts particularly, a high polish finish is preferred. A large proportion of the grit and dirt which enters cleaning water during the car washing process consists of metal particles, these particles can fall in the form of rust but are also released from the brakes of cars and commercial vehicles directly to the road surface. On a wet road cars create spray, that spray has a high metal particle content. As the following vehicle enters that spray the metal particles become attached to that car’s paintwork. Due to the fine nature of the particles it is difficult to clean the cars surfaces without embedding the particles into the washing fluid, this means every time contact is made between finished surface and wash media these particles are being pushed across the surface leading to an eventual dull surface finish. Traditional grit guards are used in an attempt to trap debris at the bottom of the washing bucket, but they may not effectively prevent metal particles from coming into contact with the car's surface.

[0004] A conventional grit guard is illustrated in Figure 1 and comprises a flat plastic base 1, consisting of a plurality of concentrically and radially formed, evenly distributed, molded ribs 2. The base 1 stands on four evenly distributed fins or legs 3, which in situ elevates the base portion 1 from the bottom surface of the opened mouth container e.g. car washing bucket. The fins 3, are arranged perpendicular to the base portion 1 and are rigidly molded to the base portion 1. Prior art grit guards are also known with an alternative rib structure or pattern, for example they may be honeycomb or lattices. It is a known limitation of grit guards which sit on fins / legs in the base of buckets that when particles travel through the molded ribs, they hit the fins and are projected back into the main volume of fluid in the open mouth container - thus limiting the efficacy of the filter. Summary of the Invention

[0005] Specific embodiments according to the present invention address the problems with prior art cleaning apparatus by providing a cleaning apparatus comprising at least one open mouth container capable of receiving a volume of fluid comprising 1) an improved grit guard for an opened mouth container e.g. car washing bucket; and 2) at least one magnet attachable to said open mouth container to entrap magnetic materials, removing them from said volume of fluid, to enhance the efficiency of ferrous metal removal. Either one of these features alone is an improvement on the prior art.

[0006] The combined, synergistic effect of these features is a magnetic particle guard system, which incorporates magnets on the bottom of washing buckets to enhance the efficiency of ferrous metal removal and an ergonomically design grit guard which guard serves as both a barrier, preventing grit and debris from circulating in the water and, in conjunction with the magnets, a filter preventing metal particles being reintroduced to the surface being cleaned. The novel grit guard restricts or reduces movement of metallic particles within the base of the container, preventing swirling and splashing of water carrying the particles, which enables the magnets to act more efficiently in capturing the metallic particles within their magnetic fields.

[0007] Considering for example a car washing process, as water is agitated within the bucket, the grit guard equipped with magnetic features, directs the flow of dirty water across the magnets at the base of the bucket / on the bucket's bottom. The magnetic field attracts and holds ferrous particles, preventing them from circulating back into the water and causing potential scratches during the washing process. The apparatus aims to provide a more efficient and effective solution for car enthusiasts and professionals alike, reducing the risk of surface damage during the car washing process.

[0008] It is a further problem with conventional cleaning apparatus comprising at least one open mouth container capable of receiving a volume of fluid that once a dirty item is rinsed in the container, girt and debris circulate contaminating the clean water. Grit guards have been used to separate dirt and particles from the clean water. However, known grit guards are ineffective at removing dirt and particles from the cleaning water. It is a further problem that metallic materials such as ferrous particles are not adequately removed from the cleaning water and dirty water underneath the grit guard can re-circulate or splash upwardly from underneath the grit guard, through the grit guard to the upper volume of water which is used to wash the cleaning cloth, so that metallic shards and other grit particles are re-introduced onto the cleaning cloth during rinsing and then reapplied to the surface being cleaned, causing scratches and surface damage to the surface being cleaned.

[0009] In a first aspect of the invention, a fluid flow - optimised grit guard is placed inside the bucket, to enhance the filtration of detritus from the cleaning water.

[0010] In a second aspect of the present invention, the magnets of the apparatus are strategically positioned to create a magnetic field at the bucket's base. The magnets are securely clipped into the bucket's structure, ensuring durability and longevity whilst at the same time being removable if so desired. In combination, the magnetic particle grit guard apparatus effectively captures and holds magnetic material e.g. ferrous particles, minimizing the risk of scratches and damage to the car's surface. The apparatus is easy to use, requiring the securely fixed magnets and robust construction of the buckets ensure the longevity and durability of the system. Moreover, the magnets or the grit guard can be adapted for use in various sizes and types of washing buckets. The combined features of the magnetic grit guard filtering system is design such that water flow is directed across the magnets on the bucket's bottom.

[0038] There will now be described by way of example a specific mode contemplated by the inventors. In the following description numerous specific details are set forth in order to provide a thorough understanding. It will be apparent however, to one skilled in the art, that the present invention may be practiced without limitation to these specific details. In other instances, well known methods and structures have not been described in detail so as not to unnecessarily obscure the description.

[0039] In this specification the term open mouth container will be understood to mean any vessel suitable for receiving and holding a volume of fluid, for example a bucket, cask, canister, or any other form of container.

[0040] In this specification like reference numerals denote like features appearing in different figures.

[0041] The term trolley will be understood to mean any supporting framework, base or chassis on wheels and includes a dolly, dollies.

[0042] The term grit guard will be understood to be any mesh, grid or framework which provides a physical barrier between detritus particles and clean water. The grit guard typically comprising a plurality of intersecting structures, for example a series of ribs or concentric circles, or a honeycomb shaped grid defining a filter.

[0043] Referring to Figure 2a and 2b herein there is illustrated schematically first and second perspective views of a cleaning apparatus 200 in accordance with a first embodiment of the present invention. The apparatus comprises a single open mouther container, in this case a bucket 201, comprising a first open end 202 and a second closed end 203. The closed end 203 being received into a trolley assembly 204 for maneuverability. The trolley assembly 204, comprising four multidirectional wheels, permitting the cleaning apparatus to pivot and be freely maneuvered in any direction around 360° from its centre.

[0044] The bucket 201 comprises substantially cylindrical walls 206 and has an upper lip 207 which protrudes from the outer surface of the cylindrical wall adjacent to the open end 202 of the bucket. The lip 207 provides a point of attachment for rotating handle 208. The rotating mechanism permitting the handle to be moved between a first lowered (as illustrated) and a second raised position for lifting or carrying the bucket. The lip 207 surrounding the neck of the bucket further comprises at least one aperture 209 capable of receiving attachment means to connect more than one open mouthed container to another. The neck lip portion 207 may also include indicia to denote the make or model of the cleaning apparatus e.g. 210.

[0045] The trolley 204 comprises raised portions 211, which upstand from the surface of the trolley to provide slots or apertures 212 capable of receiving complementary cleaning tools and nozzles e.g. hose adaptors 213 or heads for pressure washers 214.

[0046] Figure 2b is a partially exploded view of compatible cleaning tools shown mounted to corresponding holders in the apparatus of Figure 2a. The same nomenclature is used throughout to denote like features.

[0047] Figure 3a herein illustrates schematically an inverted view 300 of an open mouth container, in this case a bucket 200, capable of receiving a volume of fluid. The container comprises a plurality of magnets 301 attached thereto on an exterior underside of the container which in use act to entrap magnetic material or particles. In use the grit guard separates the volume of fluid within the container into an upper volume above the grit guard, and a lower volume which occupies a same horizontal layer within the container as the grit guard. The plurality of magnets, on the underside of the container act to retain magnetic particles in regions of the interior surface of the container near the magnets, keeping the magnetic particles out of the upper volume of water above the grit guard, and removing them from said upper volume of fluid which is used to rinse a cleaning cloth. The combined objective of the grip guard and magnets is to allow any grit particles, both magnetic and non- magnetic to sink through the grid of the grit guard and to settle within the lower layer of fluid e.g. water at the base of the inside of the container, so that when a user rinses a cleaning cloth in the container, dirt and grit from previous rinsing operations does not re-contaminate the cleaning cloth.

[0048] In the embodiment shown, eight magnets 301 are equidistantly spaced in a radial distribution around the base of the bucket on the outside of the bucket to the inner wall of the fluid containing part of the bucket. Equidistant, radial spacing is achieved by a radial spacer 302, comprising a plastic framework having a two substantially circular portions 302a, 302b and spoked extensions 302c extending therebetween, with receiving means 303 e.g. slots or molded holders located at the outermost region of the spokes for receiving individual magnet assemblies ‘X’ (see Figure 3d). The circular wall portion 302a is for rigidity and strengthening of the base round the perimeter of the central cusp or dome portion. The radial spacer 302 is received by a plurality of complementary projections (eight in the example shown) 304 on the underside of the bucket 201. The spacer 302 is connected to the underside of the bucket by a plurality of attachment means e.g. screws 305 which extend through the spacer 303 to meet the underside of the bucket projection 304. The equidistant spacing of the projections 304 is complementary to the spacing of the receiving means 303 for the magnets. The base of the bucket has regions of reinforcement 306 between respective projections 304. The areas of reinforcement may take any shape or form but in the present illustration are a substantially ‘M’ shaped region located between each respective projection 304, each “M” shaped region having a first upright side portion 320, a second upright portion 321, a first laterally extending portion 322, a second laterally extending portion 323, and a connecting bridge portion 324 between the first and second laterally extending portions.

[0049] The receiving means 303 comprise an aperture 307 which is complementary to the size and shape of the magnet assembly ‘X’ being attached. The magnet assembly ‘X’ comprises a substantially circular magnet 308 cased in a plastic housing 309. The housing 309 comprising an indent 310 to further secure the magnet to the outer circular ring 302b of the spacer 302. The plastic encased magnets “clips in” to the outer circular ring 302b of the spacer 302 enabling snap fit. This allows the magnet to be removed.

[0050] It will be understood that alternative number of magnets or a different distribution pattern could be used for example rows or stripes of magnets, or a solid arrangement of magnets in a ring around the entire base or a magnet which occupies the entire base of the bucket.

[0051] Figure 3b herein illustrates schematically an alternative inverted view of a single open mouth container capable of receiving a volume of fluid and a plurality of magnets attached thereto to entrap magnetic materials, removing them from said volume of fluid in accordance with a first embodiment of the present invention. The same nomenclature is used throughout.

[0052] Figure 3c herein illustrates schematically an enlarged view of region ‘A’ of Figure 3b. The underside of the outer region of the spacer 302 is visible, as are apertures 311 for receiving attachment means e.g. screws 305 therethrough.

[0053] Figure 3d illustrates schematically an inverted view of a single open mouth container capable of receiving a volume of fluid and a plurality of magnets attached thereto in the same orientation as Figure 3b, having a single magnet ‘X’ removed. The same nomenclature is used throughout.

[0054] Figure 4a herein illustrates schematically the magnet ‘X’ of Figure 3d. The magnet 308 is substantially circular and cased in a ‘ring pull-shaped’ plastic housing 309. The housing comprising a projecting tongue portion 404 having a part cylindrical channel 310 which snap fits over the corresponding projection of circular ring 302b of the spacer 302.

[0055] The magnet itself may comprise an indicia 401 to denote a product make and model. Figure 4b illustrates schematically and alternative embodiment of the magnet assembly ‘X’ of Figure 3d without an indicia 401. The lower surface 402 of the magnet housing 309 comprising an indent 310 to further secure the magnet to the outer circular ring 302b of the spacer 302. Additional ergonomically designed hand-holds or tabs 403 are also present to assist the attachment and removal of the magnet assembly ‘X’ to the aperture 307 of the receiving means 303.

[0056] Figure 5a and Figure 5b herein, illustrate schematically top and front perspective views of grit guard 500 in accordance with an embodiment of the present invention. The grit guard 500 is a substantially circular, disc, bowl or platelike structure comprising a grid of fins or ribs, arranged in concentric circles 501 spaced by radial supports 502, spaced around a central circular core 503 and extending to a circular outer border 504. The outer border comprises equidistantly spaced upstands or baffles 505, arranged in pairs. Each upstand within a pair 505a / 505b has a substantially sloped upper surface 506, which slopes from a first upper end 507 to a second lower end 508. The upstands 505 are inclined downwardly towards their respective partner within a pair 505a / 505b. The baffles or upstands act as a one-way sediment trap and direct suspended particles toward the magnetic fields of the magnets located on the underside of the open mouthed container. Water flowing in an anticlockwise direction around the inner surface of the container is directed by the clockwise facing open apertures formed by the clockwise facing baffles 506a, and for water swirling around in a clockwise direction adjacent around the inner wall of the container, the water flow is diverted downwardly to underneath the upper surface of the grid, by the open mouths of the anticlockwise facing baffles facing in an anticlockwise direction.

[0057] Respective pairs of upstands 505a / 505b are adjacent and spaced apart from neighboring upstands by the width of a downwardly projecting sink aperture 509. The downwardly projecting aperture 509 has an aperture wall 509 which is received into an inner cavity of the projections 304 on the underside of the bucket 201 (See Figure 7b). The plurality of evenly spaced apertures allow for dirt and grit to pass unobstructed from the upper part of the perimeter of the grid to underneath the grid. The aperture walls of apertures 509 elevate the grit guard from the base of the container and also prevent rotation of the grit guard within the base of the bucket 201 since the movement of the walls 509 is restrained by the internal cavity of projection 304. The aperture walls 509 sit in the “V” shaped centres of the “M" shaped formations on the interior of the bucket, so as to prevent the grid from rotating within the bucket.

[0058] Radially extending upright support walls 502 prevent water underneath the grid from swirling around in a circular motion, and compartmentalize the lower layer of water within the container into a plurality of segments, each segment having its own magnet.

[0059] Each circular concentric ring 501 of the grit guard has one or a plurality of downwardly projecting fins 520 extending circumferentially along the rings.

[0060] Figure 5c illustrates schematically a girt guard 500 in accordance with Figures 5a and 5b located in situ in the base of an open mouth container in accordance with the present invention. The same nomenclature is used throughout.

[0061] Figure 6a illustrates schematically a top view of a grit guard in accordance with the present invention. The same nomenclature is used throughout.

[0062] Figure 6b illustrates schematically a cross-section along axis C-C of Figure 6a, showing the disc or plate-like structure of the grit guard 500 which is on an inclined angle having a radius of curvature of 218.07mm with respect to the centre point 600 of the grit guard 500. The preferred radius of curvature is in the range of 200mm to 235mm. At the outermost edge 601 the grit guard has a height of 41,63mm in comparison to a central height of 15.28mm. Intermediate heights of 15.18mm and an angle of 23.19°.

[0063] Figure 7a illustrates schematically a top view 700 into a single open mouth container capable of receiving a volume of fluid and having a grit guard 500 located therein in accordance with the present invention. Like numerals denote like parts.

[0064] Figure 7b illustrates schematically a cross-section along axis A-A of Figure 7a, an open mouth container containing a grit guard in accordance with the present invention. The ‘m’ shaped reinforcement 306 of the lower surface of bucket 201 is visible. The lower feet portions 509 being receivable into internal cavities 701 of underside bucket projections 304.

[0065] The outer and highest most points 702 of the inclined surfaces 506 of paired upstands 505a / 505b are spaced at 127.29°from one another. Whilst it will be understood that alternative angles of orientation will be apparent to a person skilled in the art, the preferred spacing is in the range of 100° to 135° from one another.

[0066] The preferred spacing of the paired upstands 505a / 505b in combination with the radius of curvature of the grit guard and the have been specifically calculated to ensure optimised direction of the waterflow downwardly towards the lower surface of the bucket where the magnets 308 are located.

[0067] Figure 9a herein illustrates schematically a grit guard 500 according to the present invention which has feet 509 to prevent the grit guard from rotating in the bottom of the open mouth container. Figure 9b illustrates schematically an enlarged view of region ‘B’ of Figure 9a. The outermost feet 509 being receivable into the internal cavities 701 of underside bucket projections 304. Additional, smaller feet 900 are present on concentric rings 501 of the grit guard. These function to space the grit guard 500 from the floor of the bucket.

[0068] Figure 10a herein illustrates schematically the position of the magnets relative to the open mouth container and optional grit guard in accordance with the present invention.

[0069] Figure 10b herein illustrates schematically a cross section along plane B-B of Figure 10a. Figure 10c shows an enlarged view of the circled region of Figure 10b. Preferably, the magnets are space radially at angles of 45° around the perimeter of the lower part of the container and the centre of each magnet is preferably located at around 60% to 80% of the outermost radial distance of the perimeter relative the geometric central axis of the container. The central base of the bucket 1000 is domed upwardly with a cusp or dome shape 600, to receive the central ring portion 600 of the grit guard assisting in the fit and orientation of the grit guard within the base of the bucket. The cusp or domed shaped central part may take the form of a three-dimensional protrusion having in cross-sectional view as viewed in a direction perpendicular to a main geometric central axis of the container of a gaussian curve. In general, along the plane B-B, the internal surface of the container is smooth with relatively large radius corners, so that when the container is emptied of fluid, dirt does not get trapped in any sharp angle corners, and so that the container can be wiped weather clean of any debris or dirt.

[0070] Along a different plane bisecting the container and passing through the centre of the M shaped formations, on the inside of the container, the bottom of the valley of the M shaped parr smoothly runs down to the substantially flat annular circular base portion, or floor of the container so that grit and dirt particles can settle at the base of the container, with the grit guard preventing swirling motion and preventing dirt or grit passing back up through the grille.

[0071] Figure 11 a herein illustrates schematically two individual trolleys 204, each for an open mouth container and an attachment means 1100 in accordance with the present invention. The trolleys each comprise a substantially circular chassis 204 / 1101, mounted on four pivotally attached, multi-directional wheels 205. The trolley 204 comprises raised portions 211, which upstand from the surface of the trolley to provide slots or apertures 212 capable of receiving complementary cleaning tools and nozzles e.g. hose adaptors 213 or heads for pressure washers 214. The apertures 212 are also capable of receiving a complementary connector 1100 which has two set of three projection 1102, which protrude into slots 212 to form a physical anchor between the two trolleys. The connector 1100 has an arc of curvature 1103 complementary to the outer arc of the circular trolley design.

[0072] Figure 11 b herein illustrates schematically two individual trolleys for single open mouth containers attached by said attachment means 1100.

[0073] Figure 12 herein illustrates schematically a second embodiment of the present invention 1200 comprising two open mouth containers 201 connected by two trollies 204 in accordance with the present invention. Typically, two buckets are used, one for clean and one for dirty water. The two substantially cylindrical buckets 201 are each received into trolleys 204, each having a receiving aperture substantially as described in Figure 11 a&b. The two individual trollies are connected by a connecting means 1100, which is removably inserted into slots 212 in upstands 211 around the perimeter of the trolley. The connecting means is compatible with any apertures 212 allowing the trolley mounted buckets to be connected to one another in any orientation, at the user’s preference.
