DESCRIPTION OF PREFERRED EMBODIMENTS

The following description is of preferred embodiments by way of example only and without limitation to the combination of features necessary for carrying the invention into effect.

Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments, but not other embodiments.

The present description illustrates the principles of the present invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the invention and are included within its spirit and scope.

Moreover, all statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, i.e., any elements developed that perform the same function, regardless of structure.

Referring to FIG. 1, shown is a perspective view of a first embodiment of an apparatus 10 in accordance with the invention. The apparatus 10 is intended for cleaning a piece of footwear using sprayed water whilst the piece of footwear is being worn by a user, but it will be understood that it is not essential to the purpose of the invention that a piece of footwear being cleaned in the apparatus 10 is being worn by a user whilst being cleaned. FIG. 2 shows an exposed perspective view of the apparatus of FIG. 1 to better understand the structure and function of the apparatus. The term “cleaning” as used herein may optionally comprise or include sanitizing and/or disinfecting as will be more fully described below.

The apparatus 10 comprises a set of brushes 12 which between them define a footwear receiving space 14. The set of brushes 12 preferably comprises first and second laterally arranged inwardly facing brushes 12A, 12B, the inwardly facing surfaces of which define the footwear receiving space 14. More preferably, the set of brushes 12 includes a third base brush 12C whose upper facing surface defines a base surface of the footwear receiving space 14. The brushes 12A, 12B, 12C may be fixed in position with respect to a housing 16 of the apparatus. However, in some embodiments, the brushes 12A, 12B, 12C may be movably mounted within the housing 16 such that the brushes 12A, 12B, 12C can be caused to move reciprocally relative to the footwear receiving space 14. Reciprocal movement of the brushes 12A, 12B, 12C relative to the footwear receiving space 14 may be provided electrically or mechanically. In some embodiments, an electrically powered motor 15 (FIG. 12) may be provided to reciprocally move a cradle 17 on which the set of brushes 12 is mounted to thereby cause reciprocal movement of the set of brushes in a direction parallel with a longitudinal central axis A-A of the footwear receiving space 14.

It will be appreciated that the brushes 12A, 12B, 12C are selected to have bristles which, in use, are sufficiently stiff to tease dirt and other debris from one or more surfaces of a piece of footwear contacting said set of brushes 12 and yet not so stiff as to damage, e.g. scratch, the surfaces of the piece of footwear. The bristle stiffness of the brushes 12A, 12B, 12C may be selected dependent on a type of footwear intended to be cleaned in the apparatuses 10 in accordance with the invention although the intention is for the apparatuses 10 in accordance with the invention to clean a range of types of footwear. The set of brushes 12 may be manually replaceable or interchangeable with one or other sets of brushes.

Whilst in some embodiments of the apparatuses 10 of the invention, means 15, 17 may be provided to provide reciprocal movement of the brushes 12A, 12B, 12C relative to the footwear receiving space 14, in simpler embodiments of the apparatuses 10 of the invention, a user may manually move their foot within the footwear receiving space 14 to bring a piece of footwear they are wearing into contact with one or more of the brushes 12A, 12B, 12C. To assist a user in effecting movement of their foot within the footwear receiving space 14, the apparatus 10 may include a support device 18 which the user may grip when moving their foot. The support device 18 may be provided as a post 20 which depends upwardly at or near a rear edge of the housing 16. The post 20 may include a horizontally extending handle 22 for improved grip by a user.

The apparatus 10 includes a plurality of water carrying channels 24 for directing water into the footwear receiving space 14 through said set of brushes 12. As can be better seen in at least FIGS. 2 and 10, the plurality of water carrying channels 24 are preferably arranged at similarly spaced intervals around three sides of the footwear receiving space 14.

It is preferred, but not essential, that each of the water carrying channels 24 extends through its respective brush 12 such that an outlet 24A of each water carrying channel 24 is positioned near to or adjacent a surface of the brush 12 facing the footwear receiving space 14. Furthermore, it is preferred that the outlet 24A of each water carrying channel 24 comprises a nozzle arranged to spray water under pressure into the footwear receiving space 14. In order to prevent damage to footwear being cleaned in the apparatus 10, it is preferred that a part 24B of each water carrying channel 24 which extends through or partially through its respective brush 12 comprises a flexible tube which flexes with movement of the bristles of the brush 12 when contacted by a piece of footwear.

The use of water under pressure in the form of sprays from the water carrying channel nozzles is preferred as this more readily assists in the loosening and removal of dirt and/or debris from surfaces of the piece of footwear being cleaned.

Preferably, the housing 16 provides a soiled water receiving tank 26 for collecting soiled water from the footwear receiving space 14. An outlet 28 (FIGS. 4 and 11) may be provided in a base of the soiled water receiving tank 26 to enable such soiled water to be conveniently disposed of.

The apparatus 10 preferably includes a tank 30 for receiving a sanitizer and/or a disinfectant solution. The tank 30 for receiving a sanitizer and/or a disinfectant solution is arranged such that the sanitizer and/or the disinfectant solution mixes slowly with the water being directed into the footwear receiving space 14 through the set of brushes 12 via the water carrying channels 24. This may be achieved by allowing a portion of the water to be directed into the footwear receiving space 14 to pass through the tank 30 for receiving a sanitizer and/or a disinfectant solution. Alternatively, it may be achieved by arranging for the tank 30 for receiving a sanitizer and/or a disinfectant solution to drip-feed sanitizer and/or disinfectant solution into a flow of the water to be directed into the footwear receiving space 14.

The apparatus 10 may include a manually operated actuator 32 such that, when a user places a piece of footwear into the footwear receiving space, manual operation of the actuator 32 causes water to be directed into the footwear receiving space 14 via the plurality of water carrying channels 24. Conveniently, the manually operated actuator 32 may be provided at the top of the post 20 or on the handle 22. Alternatively or additionally, the apparatus 10 may include an automatically operated actuator such that, when a user places a piece of footwear into the footwear receiving space 14, a detector 34 (FIG. 12) detects the presence of the piece of footwear in the footwear receiving space 14 and automatically triggers the actuator to cause water to be directed into the footwear receiving space 14 via the plurality of water carrying channels 24.

The apparatus 10 may include a hand-operated spray attachment 36 to enable a user of the apparatus 10 to clean an upper surface of a piece of footwear received in the footwear receiving space 14 and/or clean debris from the set of brushes 12.

In the embodiment of the apparatus 10 of FIGS. 1 and 2, the housing 16 has a connector 38 for connection to an external water supply to receive water for said plurality of water carrying channels 24. The connector 38 may comprise a hose fitting enabling the housing 16 to be connected via a hose 40 or the like to a faucet 42. In this embodiment, the apparatus 10 may include a water tank 44 for receiving water from the faucet 42, the water tank 44 preferably buffering the supply and flow of water to the water carrying channels 24.

A second embodiment of an apparatus according to the invention is shown in FIGS. 3 and 4. In the description of this embodiment, like numerals, as used in the description of the first embodiment but preceded by the numeral “1”, will be used to denote like parts for reasons of brevity.
