Definitions

  • the present invention refers to an impermeable control push-button board for an automatic machine, in particular for a drink vending machine.
  • a push-button board comprising a series of push-buttons for the selection of the available drinks and for the activation of other functions (as for instance "extra-sugar", etc.).
  • Each push-button is connected to at least one LED diode, positioned close to the push-button, said LED diode indicates whether a specific drink or function is currently available.
  • a membrane 15 made of an impermeable material is shaped so as to cover the outer side of a push-button board 11 positioned inside an outer container or body of the automatic machine.
  • the membrane covers the control push-buttons 12 which project from the outer surface of the body 10.
  • the membrane is perforated by the luminous LED's 14 which show through the openings 13 formed in the outer body 10.
  • the membrane has the task to avoid the access of water, dust and other polluting agents present in the air of the environment wherein the vending machine is placed, into the inner parts where the push-button electric contacts are positioned.
  • humidity and dust and soil deposits may, in the long run, jeopardise the working capacity of the push-button board.
  • the automatic machines of the above type are usually placed in passageways or in industrial environments where said polluting agents are present in a high quantity.
  • a purpose of the present invention is to realise a push-button board provided with a membrane of the improved type which will allow to overcome the disadvantages previously discussed.
  • a control push-button board for an automatic machine in particular for a drink vending machine of the type wherein the machine is provided with an outer container wherein a push-button board for controlling the machine is contained.
  • the push-button board comprises:
  • the membrane is opaque and break free and forms, by the LED's, a plurality of dome shaped portions which have a smaller thickness than the thickness of the remaining membrane portion, so as to let pass through to the outside the light emitted by the LED's.
  • numeral 10 indicates the outer container of an automatic drink vending machine; a push-button board, indicated by numeral 11, for controlling the vending machine is contained inside the container 10.
  • the push-button board comprises a plurality of push-buttons 12, which project from the proper openings 13 of the container 10 and which project slightly from the container surface in order to be pushed by the user; the push-buttons 12 are connected, in a known way, to a corresponding plurality of luminous LED diodes, indicated by numeral 14.
  • a membrane 15 made of an impermeable material, break free and opaque to the light, covers completely the portion of the push-button board directed towards the container 10, thus forming a break free sealing barrier which is positioned between the outside and the push-button board to seal in an airtight manner said board against water, wet air and other particles penetration which might potentially be harmful for the operations of the push-button board.
  • the membrane 15 forms, by the LED's 14, a plurality of dome shaped portions 16 which repeat the shape of the LED's; the dome shaped portions 16 have a smaller thickness than the thickness of the remaining membrane portion, so as to let the light emitted by the activated LED's pass through to the outside.
  • the remaining membrane portion on the other hand, has a bigger thickness, which makes it completely opaque to the light. Thanks to this configuration, the light which passes through the thin domes 16 is uniformly diffused and it is perceived by the observer as a well defined luminous circle which is clearly visible even in the case that the side of the vending machine, wherein the push-button board is positioned, is directed towards the incoming sun or artificial light from the outside.
  • the disadvantage of the traditional vending machines is therefore overcome, as discussed in the preamble of the present description.
  • the membrane 15 is of a dark or bright colour, which makes the membrane portion, surrounding the dome shaped portions which cover the LED's, completely opaque.
  • the most preferred materials, which are used for producing the membrane according to the present invention are the same as the traditional membrane materials, i.e. natural or synthetic rubber.
  • the LED diodes do not remain uncovered and therefore it is not necessary, on the one hand, to make the various parts which form the push-button board with dimensions suitable to satisfy the minimum requirement of 8 mm distance previously mentioned, and, on the other hand, the problem of touching a diode with a hand is avoided.
