DESCRIPTION:
BRIEF SUMMARY
The invention concerns a device for disinfecting and cleaning those parts of persons, animals and objects generally that come in contact with the ground.
It is known that much dirt is present on the surfaces of roads and outside areas, dirt that includes animal excrement, residue of edible materials and other organic substances likely to contain bacterial flora, viruses etc. Dirt of this kind can easily cause serious diseases of a contagious nature.
Good habits of hygiene include washing and disinfecting the hands, the mouth and the whole body, cleaning clothes, habitations, carpets and shoe uppers but little attention is paid to the soles of footwear and those parts of objects in contact with the ground.
Shoe soles in particular spontaneously pick up infected material which is then carried into homes, offices, hospitals, public places and wherever people walk in. Inside buildings the temperature is regulated for human comfort but at the same time this warmth is perfect for the growth of bacteria and viruses which develop rapidly and spread throughout the environment with harmful effects.
The same drawbacks apply to the passage of animals and any rolling means such as the wheels of wheel-chairs, trolleys and the like all of which carry in dirt from outside on feet and wheels.
Patent BE-A-890 907 discloses a sterilizing device that comprises a flat basin containing a spongy cartridge impregnated with a sterilizing product, of the `disposable` kind with a grating on top of it.
When an object passes over said grating, the compressed cartridges transfers the sterilizing product to the object.
The whole device can be made of cheap material as is usual for disposable kinds of articles.
The cartridge is changed by inserting it into the device from above and it is kept stable by gravity.
Patent EP-A-60148 similar discloses a sterilizing device comprising a replaceable cartridge put in through an aperture at one side.
The drawback to these devices is their operating lifetime prior to cartridge replacement; they need frequent replacement and adequate maintenance. Cartridge performance is obviously limited by their having to be thrown away after use which also means limitations as to size and choice of materials, necessarily cheap.
U.S. Pat. No. 2,989,965 discloses a device for decontamination of radioactive areas.
At the top of a tank of decontaminating liquid there is a fixed platform for feet to stand on, at a level lower than the surface of the liquid which, as it becomes contaminated, can be filtered or replaced.
Replacement is not automatic or spontaneous following the passage of feet so that an operator is needed or some arrangement independent of the movement of people.
SUMMARY OF THE INVENTION
It is an object of the present invention to eliminate or lessen the disadvantages referred to above in an extremely simple device without cartridges to replace, and having means for feeding disinfecting liquid a feed which may even be spontaneous, offering maximum and long-lasting effectiveness.
The device according to the invention disinfects in their passage over it, parts of persons, animals and objects generally that come in contact with the ground, especially the soles of footwear.
In place of the disinfecting cartridge proposed by patent BE-A-890 907, in the present invention the device according to the invention is provided with a container suitable for replenishing the disinfecting liquid transferred to persons, animals and objects generally passing across the device.
According to the invention the device has a shallow flat-bottomed tray containing a flat spongy body impregnated with disinfecting liquid and above the spongy body an elastic grating whose upper surface is practically flush with the edges of the tray. The tray is of a rectangular form and its four sides are channel-shaped, i.e. trough-shaped, in cross section.
The channel-shaped peripheral sides can accommodate the edges of an internal opening cut out in a doormat.
the internal opening in the doormat corresponds to the shape of the tray.
