Description
[0022] The features and advantages of the invention will be more clearly apparent from the detailed description of some embodiments thereof, illustrated by way of non-restrictive example, with reference to the attached drawings, in which:
[0023]
[0024]
[0025]
[0026]
[0027]
[0028]
[0029] With reference initially to
[0030] In a preferred embodiment, the apparatus 100 is flat and preferably substantially rectangular.
[0031] This shape advantageously allows the apparatus 100 to be installed in a similar way to a traditional doormat for cleaning shoes.
[0032] As will be more clearly apparent below, the shape and features of the components of the apparatus 100 according to the present invention prove particularly suitable for making said apparatus as flat as possible.
[0033] Still in connection to
[0034] As will become clearer below, the bearing surface 1 is movable relative to the supporting structure 10 with respect to a bearing direction P of the foot. In a preferred embodiment, this direction corresponds to the vertical direction, but obviously alternative embodiments can also involve alternative orientations for the bearing direction P, for example tilted.
[0035] In one embodiment, the supporting structure 10 comprises a base 101 and a lateral frame 102, which define a housing volume for the components of the apparatus 100, illustrated in detail below.
[0036] As can be seen from
[0037] It is therefore obvious that this pressure can be easily exerted by the action of the foot, using the weight of the user themselves.
[0038] Preferably, the supporting structure 10 comprises an abut member 103, more clearly visible in
[0039] In one embodiment, the abut member 103 is defined by means of an inner frame that is concentric with the lateral frame 102. Preferably, the abut member 103 has a substantially L-shaped cross section. In this way, a portion of the abut member 103 bears on the lateral frame 102, and a portion perpendicular thereto acts as backing for the bearing surface 1.
[0040] Even though alternative solutions can also be provided for the abut member 103, it must be observed that the present embodiment makes it possible to keep as much of the housing volume of the supporting structure 10 available as possible, and at the same time to guarantee sufficient resistance in order to support the weight of a person.
[0041] With reference now to
[0042] Preferably, the reservoir 2 and the delivery unit 3 are housed inside the supporting structure 10, at least in part. Even more preferably, they are both completely housed inside the supporting structure 10.
[0043] In a preferred embodiment, the delivery unit 3 comprises spray nozzles 30 facing the bearing surface 1 and spaced apart from one another. The sanitising fluid discharged from the delivery unit can thereby be sprayed towards the bearing surface 1, pass therethrough by methods described in greater detail below, and reach the sole of the footwear worn by the user.
[0044] In one embodiment, the spray nozzles 30 are interconnected by means of respective pipes 31. Preferably, the pipes 31 are arranged below the reservoir 2.
[0045] In a preferred embodiment, the bearing surface 1 is placed above the reservoir and the delivery unit 3.
[0046] Accordingly, for that purpose, the reservoir 2 comprises a plurality of through-holes 20 for allowing the passage of connecting segments 32 for connecting the pipes 31 to the spray nozzles 30, thus allowing the fluid to be sprayed towards the bearing surface 1, as more clearly visible in
[0047] Preferably, the bearing surface 1 comprises a plurality of through-holes (not visible in the figure), which allow the sanitising fluid to pass through said bearing surface so that said sanitising fluid can reach the sole of the footwear when said footwear is bearing on the surface 1.
[0048] The nozzles 30 can thereby be placed below the bearing surface 1, allowing the fluid to pass towards the sole of the footwear in any case.
[0049] In a preferred embodiment, the bearing surface 1 comprises a layer made of metal foam having a plurality of interconnected pores suitable for allowing the passage of said sanitising fluid between opposite sides of said bearing surface 1, thus defining the above-mentioned through-holes.
[0050] This solution proves particularly advantageous since it combines robustness, simplicity of production and effectiveness in use.
[0051] The sanitising fluid is delivered through the nozzles by means of a compressible member 4 that is operatively associable with the bearing surface 1.
[0052] In greater detail, the compressible member 4 can be compressed as a result of movement of the bearing surface 1 in the bearing direction P.
[0053] To this end, in one embodiment, the compressible member 4 is placed below the bearing surface 1 such that, as a result of the bearing surface 1 being lowered through the action of the foot, said bearing surface comes into contact with the compressible member 4, compressing it.
[0054] In a preferred embodiment, the compressible member 4 is connected to the reservoir 2 by means of respective pipes 42, which are partially visible in
[0055] In this way, the variation in volume produced as a result of the compression of the compressible member 4 allows the sanitising fluid present in the reservoir 2 to be forcibly pushed towards the delivery unit 3, consequently delivering it from the respective nozzles 30.
[0056] In a preferred embodiment, the compressible member 4 defines a hollow internal portion (not visible in the figures), such that this reduction in volume can take place as a result of the movement of the bearing surface 1 in the bearing direction P. Preferably, the hollow portion is in fluidic communication with the reservoir 2 such that the fluid inside said reservoir can be forcibly pushed by means of the pressure created by the compression of the compressible member 2.
[0057] With reference to
[0058] In other words, the compressible member 4 is made like a bellows.
[0059] A resilient return member 40 is thereby defined, allowing the compressible member 4 to be restored to the expanded condition after it has been compressed and the fluid has been forcibly pushed towards the nozzles 30.
[0060] Obviously, for that purpose, the pipes 42 and 31 will be provided with suitable non-return valves (not illustrated in the figures).
[0061] In this way, each time pressure is exerted on the bearing surface 1, a cycle of sanitising fluid discharge takes place, which can thus affect the sole of the footwear bearing on the surface 1.
[0062] Once the bearing surface 1 is crossed, the bearing surface 1 can rise again, returning to the initial position and restoring the compressible member to its initial conditions, thus allowing the sanitising cycle to be repeated the next time a user passes over said bearing surface.
[0063] It should lastly be noted, that, as illustrated in
[0064] For example, in the present embodiment, in which the supporting structure 10 has a rectangular shape, the reservoir 2 is divided into two parts, between which the compressible member 4 is placed.
[0065] The space occupied can thereby be optimised, allowing sufficient autonomy to be provided for an apparatus of limited thickness.
[0066] It should be noted that, in one embodiment, the bearing surface has dimensions such as to allow one foot to be supported thereon. For sanitising both the right and left shoes when a person passes over the bearing surface, two paired apparatuses of the type illustrated in
[0067] In an alternative embodiment, illustrated in
[0068] Each bearing surface 1 is associated with a respective compressible member 4 and respective nozzles 3 such that only part of the apparatus is involved in the delivery of sanitising fluid.
[0069] This embodiment is particularly suitable for use in passageways in public places, for example at the entrance to a hospital, since during transit the user will probably place both his/her feet on a particular bearing surface 1, thus sanitising his/her soles simply by passing over said bearing surface.
[0070] The invention therefore solves the proposed problem, simultaneously achieving a plurality of advantages, including the possibility of producing an effective sanitising action without requiring connection to any external power sources or rechargeable sources.
[0071] Furthermore, the apparatus can be actuated simply by resting the foot on the apparatus, therefore utilising the user's actual weight. Consequently, this means that said user does not have to exert any force.
[0072] Furthermore, in this way the apparatus can also be actuated by simply treading on the bearing surface, as happens naturally when the user passes over it.
[0073] Therefore, by placing the apparatus at the entrance to a public place, it is possible to sanitise the soles of the shoes of people going there, with the considerable benefit of cleanliness and hygiene inside that place.
[0074] Furthermore, since the apparatus according to the present invention is fully autonomous in its operation, it is possible to use several apparatuses side by side, thus creating a wide treading surface involved in the sanitising action. This therefore also allows the apparatus to be used at the entrance to public places, such as hospitals. In this case, the consumption of sanitising fluid can be optimised by using sufficiently small bearing surfaces for delivery to take place only on the part where footwear is actually placed.
