SANITY PHASE 2- THE PROTECTIVE GEAR

Field of Invention
The present invention relates to the use of a protective gear in form of a sanitary disinfectant pad measuring 20-50 cm2 and 5-20 mm thick which is used to wipe trolleys in shopping centres, especially supermarket and airports. A sanitary pad is removed from a roll fixed on a rod embedded on one of the two rods supporting the trolley handle by pulling it and wiping the handle thereby disinfecting it. The used pad is thrown into a kit or disposal container fixed alongside the trolley to avoid littering.

BACKGROUND OF THE INVENTION
The term "trolley" as used below means transport containers which are commonly used in supermarkets and large shops in order to assist customers in the transportation of goods selected in the supermarket to the cash till and optionally the transport of the purchased goods from the till to the car park. It also extends to Airport trolleys used in transporting luggage from the belt area. Owing to the frequent use of their handles, the said handles get infected within a short time as they are handled by many customers. For hygienic and health reasons, it is necessary to clean the trolley handles before handling.

Airports, supermarkets, grocery stores and the like provide carts and trolleys for customer's convenience that are adapted to hold the customer's selected purchases. Customers handle, interact and touch trolleys with hands and many articles some of which are usually soiled, contaminated and infected. The trolleys thus contain food,

including liquids, which at times are spilled or come in contact with the trolleys surfaces. Many customers have small children who are carried in the trolleys.

Not only is it unsanitary to continue to use dirty, unwashed trolleys but at times such use could promote the spread of disease and infectious micro-organisms which multiply where food items have been left.

Since it is good sanitary practices to have the trolleys cleaned at regular intervals, a definite need exists for a system, which will clean ordinary airport or supermarket trolley handles in a short period of time. The standard wire rod or mesh basket trolley is provided with a handle, a basket mounted in a frame, and generally four caster mounted wheels. The trolleys vary gready in design, however, they all present a handle and basket to allow the purchaser to hold and move their selected items and in most cases they provide a seat and pivoting support for the seat for the carrying of infants and small children.

Due to the nature of the produce hauled in the trolleys and the gradual accumulation of ftlth upon the trolley handles, it is highly desirable that the handles be periodically cleaned and even more importandy by every new user. Failure to thoroughly clean such trolleys could reduce the number of customers to a particular supermarket and airports. This is because customers prefer not to use unsanitary, soiled trolley handles. On the other hand, if the airport trolleys were periodically cleaned and sanitized the food oudet store and supermarkets could advertise such a fact, which would gready enhance the trade at that oudet.

The standard practice at most stores which utilize shopping trolleys is to clean the trolley handles manually by the use of high pressure steam or hot water hand towels and then to have the detergent and hot water rinsed away by the use of a fresh water spray. Unfortunately, manual washing of trolley handles is inefficient so that it costs far too much to clean trolley handles. Such inefficient manual washing of so many carts is too costly. It also leaves a mess in the parking lot. It is not uncommon for large airports and supermarkets to have 400 or more trolleys in their establishment. The supermarket owner may be forced to increase the interval between washing cycles and thus deprive his customers of the clean, sanitary trolley handles that they desire.

In order to provide for an automatic trolleys washing system, some inventions have been made which somewhat automate the process thereby eliminating the need for a total manual washing. Although automation reduces the cost of washing the trolley, the prior art cleaning devices for supermarkets suffer from a number of definite drawbacks.

DISCUSSION OF PRIOR ART
According to the prior art, the present invention is simple in its applicability and there are no patents in force in Kenya on this product. However, there are a few quoted publications or patent documents that exist in other countries but are not similar to the present invention.

Prior art cleaning devices for supermarkets, airport and grocery trolley and cart handles are generally of the type which provide an enclosure, spray nozzles, and a means for introducing the trolleys in a nesting fashion and retrieving them upon having the trolley handles sprayed with a detergent solution. This has proved very cumbersome. Such devices do not provide for a readily mobile washing of trolleys nor a complete system in which the trolley handles are sanitized and ready for customers use. Also, such devices generally fail to provide for the re-circulation of fluids employed so that the fluids are wasted whereas they could be recycled to more efficiently wash the trolley handles.

Most of the airport trolley handle washing devices provide for a semi-automatic washing of the trolley. However, none are known which provide for a sanitary protective gear comprising a disinfecting pad for wiping handles of trolleys in supermarket and airports.

Examples of known trolley cleaning devices can be found in U.S. Pat. No. 2,997,048 to Gertken, et al. issued Aug. 22, 1961, U.S. Pat. No. 3,179,117 to Gibson, et al. issued Apr. 20, 1965, and U.S. Pat. No. 3,698,029 to Pulliam issued Oct. 17, 1972.

Other prior art in cleaning of trolleys include:

Patent No. W0/1988/010496 by AUTOMATION FACILITIES LIMITED KINGSBURY, Philip, Charles, Orlando GUTCH, Christopher, John, Worsley discloses a cleaning cassette for cleaning the heads of streamer tape drives which has a wiper arm carrying a foam wiping pad at one end and pivoted in the casing at the other. A pick-up wheel engages the capstan of the drive and reciprocates the wiper arm, through gear wheels and a crank arm, to cause acute movement of the pad across the head. The pad has a thicker central portion and thinner wings, and a metal base strip is compressed over the wings. Although the effective head cleaning is achieved in a simple and practical structure without excessive headwear, it does not refer to trolley handles at the airport and supermarkets.

The invention proposed in German Patent De 198 57 A 1 which relates to a mobile cleaning and washing plant for shopping trolleys of all kinds and in which a washing box together with a cleaning fluid or water treatment plant and connecting pipes is mounted on a base frame and attached to a transport device. To clean the shopping trolleys, the mobile cleaning and washing plant, when at the desired place of use, is either placed on the supports of the base frame in front of the transport device, or remains on the transport device during the cleaning operation. Such device does not involve a wiping disinfecting pad.

In the German Utility Model Application DE 298 683 Ul, a mobile washing container is disclosed which can be used in particular for cleaning shopping trolleys, mesh boxes and merchandise baskets. Tills mobile washing container is a standard Euro-container. After the residual waste has been conveyed into a collecting tray by means of a suction fan, the transport containers to be cleaned are moved through a washing installation which includes high-pressure jets, movable and adjustable washing brushes, disinfectants jets, a drying-air duct and an oil spray device for spraying the wheels and wheel pivots of the transport containers to be cleaned.

Spraying of the transport containers to be cleaned with a disinfectant by means of disinfectants jets specially provided for this purpose ensures additional hygiene. A re-circulated water cleaning arrangement which carriers out a water treatment process is also integrated in the mobile washing container. Because it has an independent power supply, this washing container can be used everywhere without being dependent on external power supply arrangements. However, the disclosed invention teaches manual application of a trolley handle wiping sanitary pad.

German Utility Mode Application DE 299 01 282 Ul relates to a washing system for shopping trolleys, which is equipped with its own power supply unit. This can be preferably a diesel unit, which generates electric current in order to operate the electrical, pneumatic, and hydraulic components contained in the washing system disclosed. The washing system also includes a purification component, which purifies the used cleaning fluid so that said fluid needs to be changed less frequendy. In addition, a blast air-drying system is integrated to dry the shopping trolleys after washing. The washing system also includes components, which lubricate the wheels and wheel axles. This contrasts the present invention in that it does not involve the use of a sanitary pad embedded on the trolley to wipe the handles.

Patent application W0/2005/020776 by SHIN, Kwang-chel discloses a wiping pad for private parts for use by females to clean the vaginal region after urination. The feminine hygienic pad comprises an absorptive layer for absorbing urine, a vaginal contact layer for coating one surface of the absorptive layer in order to prevent the absorptive layer from coming into direct contact with the vaginal region while enabling absorption of urine on the absorptive layer, and a hand contact layer for coating the other surface of the absorptive layer in order to prevent the absorptive layer from coming into direct contact with the hands. The said teaching of the use of a wiping pad for private parts does not relate to cleaning of handles of trolleys.

Very few devices in the known art relate to the wiping of the trolleys and none known prior art are directed to provide such disinfectant pad in which sanitizing is also provided for in the wiping of the trolley handles as claimed in the present invention.

In a different type of apparatus as disclosed in U.S. Pat. No. 3,736,948 to Crosswhite issued June 5, 1973, an apparatus for washing hospital carts is disclosed in which a sanitizing fluid from a remote source is used to spray upon hospital carts. U.S. Pat. No. 4,279,263 to Pulliam issued July 22, 1981, discloses a portable expandable structure for manually washing carts, which includes a type of recirculating pump system.

Although the prior art discloses a number of interesting cart washing inventions, a complete cleaning and sanitizing system employing sanitizing fluid in a pad adapted for a trolley, truck or trailer handles is not shown. Such an invention would greatly reduce the costs of cleaning supermarket trolley handles, thus allowing the customers and store owners to have the trolley handles cleaned and sanitized at a more frequent interval.

Accordingly, a need exists for a protective gear involving a trolley employing sanitizing fluid and being adapted for carriage on a trolley so that it can be handled and taken to a number of establishments including till while clean. Such a system would provide a simple, hygienic, inexpensive apparatus that could wipe a trolley in a matter of seconds, disposed of on trolley itself, service with complete confidence of customers while clean. A cleaning system of that type would provide a system that is simple in design, easy to maintain, and easy to adjust to different types of trolley. Such a device should be easily repaired, not subject to damage by proper use and simple to manufacture. The instant invention is directed to all of these needs as well as to others as explained in the following summary.

SUMMARY OF THE INVENTION
The primary purpose of the invention is to provide a sanitary pad measuring 20-50 cm2 and 5-20 mm thick for cleaning for trolley handles which is save, easily adapted to a number of designs of trolleys, and provides for a disposable kit used so that when the operator has finished wiping the trolley. No evidence of detergent, sanitizing fluid, grit, grime, or other debris is left as residue. The device is self-contained in that a supermarket trolley can be moved and exited in a complete sanitized state without the necessity for employing additional stations or process steps.

The purposes and features of the invention are obtained by providing kit installed alongside to avoid littering. The trolley can move through the tunnel while clean. The pad is provided for a sanitizing fluid so that prior to with a sanitizing fluid to
