DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electronic marking device, intended most particularly but not exclusively for the recognition of pieces of clothing.
2. Description of Related Art
Establishments using numerous personnel, this personnel having to wear particular work clothes, as for example white coats for hospital personnel or overalls or other protective clothes for the personnel of certain factories, are generally customers of a firm renting out work clothes, this firm generally also being able to ensure regularly the cleaning and repair of these clothes.
It is necessary for the establishments using these clothes, as well as for those renting out and/or repairing them, to be able to recognize each of the garments individually, mainly after the latter have been laundered and/or repaired. Actually, first of all the rental firm may have rented the same type of garment to several establishments; it is therefore necessary for each garment to be routed to its own holder, the garment in question generally being adapted to the function and the size of the latter, and finally the wearer of the work garment is generally glad to know that the garment he receives is the same as the one he had sent to be cleaned. The problem of recognition is still more complicated when the user establishment rents work clothes from several rental firms, or when the latter does not ensure the upkeep but when the laundering is ensured by one or more other different firms. It is therefore necessary for each garment to be marked individually and bear is ensured by one or more other different firms. It is therefore necessary for each garment to be marked individually and bear indications relating to the rental firm, to the using establishment, as well as to the holder of the garment, indications concerning the cleaning and repair firm or the department in which the holder works also being able to appear in the marking. The above indications further serve for a knowledge of the stocks of clothes, their circulation, and may facilitate the various invoicing of services rendered.
Generally, the necessary indications appear on a label fixed permanently or detachably to the garment and bearing these indications in plain form or encoded, for example an alphanumeric code or a bar code. In order to avoid manipulations and disputes, it is advantageous for the label to be fixed permanently to the garment, but in this case the marking appearing on the label may disappear after one or more laundering operations, depending upon the conditions and the products used for laundering. The presence of the label, according to the material used for the latter, may also hinder the cleaning operations, particularly the final ironing of the garment. Moreover, in case of changing one of the elements of the code, it is necessary to change the label, which may be long and costly in the event that engraving is to be carried out. But the major drawback resides in the fact that for each allocation of the garment in question, it is necessary to find its label and to read it, which increases the number of manipulations.
The application EP-A-0 376 062, which is considered to be the closest prior art, describes an electronic ciruit composed of an integrated circuit chip comprising a memory, connected to the two ends of a wire of a winding. This circuit is intended to be integrated into a rigid object, as for example a card of the credit card type or a key. In view of the rigidity and the use of the support object, the constraints of flexibility and of behavior at temperatures required for this device, especially for its fixing to the support object, are essentially different from those necessary for the device according to the invention.
A first object of the invention is therefore to propose a device for marking with a code, capable of being read by electronic means and capable of being garment having to undergo cleaning operations at high temperature and/or using noxious products.
