Definitions

  • the invention relates to devices intended to provide controls, preferably door openings, using coded signals.
  • the person in charge of a specific room or apparatus access to which is controlled by a lock which can itself be controlled by a code device of the above type, may be eager to authorize this access to a third party for only a limited period, this period depending on the application envisaged and which can vary to a large extent, being for example a quarter of an hour for the operation of a predetermined device or a day for availability of a hotel room.
  • the box assigned to the control of the lock is entrusted to each user temporarily authorized at the start of the authorization period and this box must be handed over by this user to the person in charge. the end of this period.
  • the object of the invention is, above all, to eliminate this drawback.
  • each transmitter unit of the type in question is essentially characterized, according to the invention, in that it includes timing means capable of automatically and definitively neutralizing the code which is recorded therein at the end of a given time T, elapsed from a predetermined time t, which is in particular that of the registration of this code and in that it is free of means making it possible to reactivate the neutralized code.
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
  • the single figure of this drawing schematically shows a code control device established according to the invention.
  • any coded electrical control such as, for example, unlocking the lock of a door (not shown) possibly followed by the automatic opening of this door.
  • the current source 3 may be a battery or one of the components of a transformer of which another component would be a loop surrounding the location where the box 2 must be located to ensure the emission of the signals S.
  • the lock to be controlled is associated with a receiver comprising means suitable for receiving the signals S and for transforming them into signals which can be used electronically, a memory in which a reference code R has been recorded, means for comparing with the code R the code C carried by each received signal S and means for transmitting an electrical control signal E each time there is identity between the two codes C and R, and said lock is itself arranged so that it can be actuated by said control signal E.
  • Such coded control remains possible as long as the electronic circuit 5 is able to develop coded signals S and the lock to be unlocked is able to receive these signals, to identify them and to use them.
  • the essential object of the invention is to automatically put an end to this possibility of ordering at the end of an authorization or validation period of predetermined duration T, in order to make impossible the coded orders in question by the carrier of the box 2 considered beyond said period.
  • the housing 2 incorporates timing means capable of automatically neutralizing the code C in question at the end of the period considered, which begins at a predetermined time t.
  • This instant t is preferably that of the recording of said code in the memory 4, which instant generally coincides with that at which the box is entrusted to the authorized user.
  • timing means in question have been shown diagrammatically in the drawing by the block 8 supplied from the source 3 and suitable for attacking (arrow g) the memory 4 for the purpose of neutralizing this memory.
  • This neutralization is ensured in particular by erasing the code C recorded in the memory, or by breaking the link (arrow h) by which this memory instructs the processing circuit 5.
  • the box 2 can no longer transmit coded signals S and its carrier can no longer unlock the lock controlled by these signals.
  • Said housing has therefore become inoperative.
  • the appropriate code C can start again. be recorded at any desirable time in the memory 4 of this box, which again makes it suitable for unlocking said lock for the duration T, above from a new instant t l .
  • the first information can be very simply obtained by displaying on the box an all-or-nothing validity signal, such as the lighting of an indicator light 9 or the appearance of a contrasting sign on a neutral background. , made using liquid crystals.
  • this display can be ensured only in response to the pressing of a verification push button 10 associated with an appropriate switch 11.
  • the second information can be given by displaying on the unit an evolving validity signal, that is to say capable of changing from the start to the end of the validity period, preferably progressively.
  • Such an evolving signal can be constituted for example by a series of contrasting points generated by liquid crystals on a neutral background, points the erasures of which follow one another step by step over time, or even by a digital display.
  • n being an integer greater than 1 and in particular equal to 2
  • the number of codes stored in the memory 4 of the housing 2 and suitable for instructing the electronic circuit 5 is equal to n
  • these codes C i being an integer between 1 and n
  • these codes C are recorded simultaneously in the memory 4, their respective periods of validity T ; are different and start at times t ; which may themselves be different but are preferably confused.
  • each press on button 1 results in the emission of a beam of j signals Si and the lock receiving all of these signals is effectively unlocked if, and only if, the code associated with it is one of the j codes valid at the instant considered.
  • the multiple recording in question results in the emission, for each press of the button 1, of single signals coded j times, j varying from 0 to n according to the instant of said press, signals suitable for unlocking each lock of different types, each type i lock being sensitive to those of said signals, which are coded n + 1 - times or more.
  • the housing 2 can be arranged in such a way that each depression of the push button 1 ensures the emission of a single coded signal S.
  • the data in question are not permanently saved in the boxes and are introduced there by the person in charge using a programmer.
  • Said data may themselves have been previously recorded, at least in part, in said programmer, or they may be directly composed on this programmer using a keyboard or in any other desirable manner.
  • the programmer is arranged in such a way that each of its implementations requires the prior composition of a secret code or even the use of a special key coded in any desirable manner.
  • Means inviolable by the user can be provided to modify the start and / or the end of each validation period recorded in the box.
  • This box can also be arranged in such a way that it lends itself to the reading of the various information recorded therein, and this using a reading device specially designed for this purpose and available only from the person responsible for the boxes. .
  • This reading allows said manager to take stock of the respective authorizations of the various boxes, either individually during the presentation of each box, or globally after gathering all the boxes distributed.
  • a special mark can be assigned to each code making it possible to identify the wearer of the box receiving this code.
  • Each box can also be arranged so as to assign to each coded signal emitted by it a special mark identifying this box, a mark which can be used for recording and / or display purposes by the locks then specially arranged accordingly and / or by the above-mentioned reading device.
  • Each box can be arranged in such a way that each code stored in its memory can be easily neutralized by voluntary external intervention, even before the corresponding validation period has expired.
  • This external intervention can be the pressing of a push button provided for this purpose, or even the tearing of a clean part to cut an electrical connection.
