Definitions

  • the invention relates to a safety device for an accommodation with a first room, at least one second room and an intermediate room located between the first and second room and to be closed by a first and a second door respectively, comprising locking means for locking the doors and an electronic control means for controlling the locking means.
  • microswitch which is fixed to the post at the hinged side of the door.
  • a microswitch is very critical as regards its adjustment, as there is a danger that the microswitch only switches over after the door has been opened so far that before the microswitch would switch over on the door being opened said microswitch can be manipulated by hand as a result of which a closed position of the door can be simulated, making sabotage possible.
  • said microswitches are adjusted so critically in practice that there is a danger that even with a closed door the microswitch does not switch over to signalize the door being closed.
  • both the first and the second door can be kept open or can be opened, as the case may be. It is even possible for the first door as well as for the second door to be opened simultaneously by an operator of the safety device, which lays an unnecessarily heavy responsibility on said operators.
  • the invention has for its purpose to remove at least one of the above-mentioned disadvantages and/or other disadvantages of known safety devices and for that purpose provides a safety device of the kind mentioned in the preamble, which is characterised in that it is further provided with closure sensor means for feeding a respective open signal to the electronic control means with a non-closed position of the doors, which control means, at least in response thereto, selectively controls the locking means.
  • a closed position of the door means the door being shut and/or locked.
  • a closed position of a door implies that the door is both shut and locked.
  • a door being closed (or open) is preferably being scanned by an inductive approach sensor, whilst the door being locked (or unlocked) is preferably scanned by a bolt switch.
  • the lock ing means are preferably cooperating, possibly modified bolt locks and day and night locks on the one hand and electric closing plates with independently operated door openers on the other hand.
  • an inductive approach sensor which is a coil with open core, activated by a permanently magnetic part of e.g. ferrite and is incorporated in an oscillator circuit with a circulating amplification smaller than one which coil is incorporated in a circuit with a level detector and works at a frequency of the magnitude of 30-40 kHz whereby the inductive approach sensor only responds with a certain distance between the permanently magnetic part and the coil in a very narrow range of e.g. 1-2 mm, whereas said coil does not respond with a maximum output (highest Q-factor), in order to prevent that all this can be sabotaged by bringing a permanently magnetic part into contact with the coil in a non-closed position of the door.
  • the electronic control means may comprise a microprocessor or programmable microcomputer, but may also be built up from discrete components, which may be considered substantially logical elements, such as operational amplifiers.
  • the electric closing plates may be driven by thyristors.
  • the electronic control means may further be provided with visual and/or sound producing signalizing means, such as buzzers, light-emitting diodes, which may possibly be driven intermittently by a timer for visualising the open position of a respective door.
  • Said signalizing means may be provided on a control panel of the electronic control means, beside the keys for opening a respective door after manual operation insofar as the system allows so. Also the closed position of doors may be visualized.
  • control panel is provided with a key switch, which may also or as well be provided elsewhere, in order to switch the system on or off, whereby preferably all doors are accessible from both sides when the system is switched off.
  • a timer dial may be connected in series to the key switch and preferably an emergency switch is connected in parallel to the key switch in order to switch the system off in case of an emergency.
  • Said emergency switch is preferably located in a second room, possibly in the same second room as where the control panel is located.
  • first room and every second room may be provided with several doors, whereby it may be indicated on the control panel exactly which door is or has been open. Furthermore several second rooms may be provided, whereby every second room except the last second room may be looked upon as an intermediate room in relation to the operation of the respective doors.
  • Fig 1 of the drawing illustrates five possible situations I-V of the accessibility of a first, left-hand door and a second, right-hand door in relation to always two directions of access, whereby “o” means inaccessible and “t” means accessible.
  • a buzzer preferably mounted on the control panel of the electronic control means, sounds in the second room.
  • the safety sluice and the second room may form part of a cash box in a bank, a department store, a jeweller's shop etc. and a cashier can look from the second room, through a wall preferably bullet proof, impact proof and transparent, into both the intermediate room and into the first room, at least in the vicinity of the first door, in order to make sure, both with regard to the first and the second door, whether the person who is ringing is authorized to enter the second room.
  • the second room may also be a vault or make access to a vault possible. Said vault need not necessarily be on the same floor as the second room and may even be located in a second second room, whereby the first room serves as a second safety sluice.
  • the control means has as it were a modular building-up with regard to always the operation of two ( a first and a second ) doors.
  • the afore-mentioned first second room may, therefore, as regards the system under consideration, be looked upon as an intermediate room.
  • several intermediate rooms may be connected in cascade, as it were, whereby a non-final second room may also be looked upon as a first room.
  • the electronic control means according to the invention is adapted and/or programmed so that by unlocking the second door the first door is automatically locked, making it impossible again to open the first door as well when the second door is open, as a result of which sabotage can be prevented.
  • the "being closed" criterion is that the door is shut and that the door is on the lock, i.e. the bolt is in the closed closing plate or electric door opener. It has become apparent namely that when only the door being closed, i.e. the door being shut is taken as a criterion, it will be possible, seeing that the standard distance between the first and the second door is 1.5 metres, to open the first door as quickly as lightning from the intermediate room while the cashier pushes the button for opening the second door, as a result of which a situation with both the first and the second door being open is created. According to the invention this undesired situation is prevented.
  • situation III In countries where legislation permits so an extra situation might be provided between situation III and situation IV, which extra situation may possibly be effected by the cashier and in which the second door is inaccessible from the intermediate room, as in situation III and the first door is inaccessible in both directions of access, as in situation IV, which makes it possible that when the cashier only notices when the person is already in the intermediate room that this is an unauthorized person he/she can keep this person locked up in the intermediate room, therefore, until the person can be heard by the competent authorities or can be arrested respectively.
  • the safety device may e.g. be put out of operation from the second room by driving an emergency switch, e.g. in a small case with a transparent window which can be smashed with a small hammer detachably attached to the case or similar attribute, after which the emergency switch can be manipulated.
  • Putting the device into and out of operation can also be carried out automatically by a programmed timer, in which timer weekly or monthly programmes may have been programmed, indeed even a yearly programme inclusive of holidays, Sundays and festival days.
  • the locking means of a door comprise in an embodiment a bolt lock 30 fixed to a plate 40 and day and night lock 32, as well as door openers 37 and 38 cooperating therewith and being provided on a closing plate 36, to which closing plate also an inductive approach sensor has been provided, whilst a bolt switch (not illustrated) has been incorporated in the electric opener 38.
  • Closing plate 36 has naturally been mounted in the door post opposite the side of the door in which the plate 40 has been mounted.
  • the bolt lock may be modified in the sense that it is not operatable, neither by e.g. a latch, nor by e.g. a cilinder lock.
  • the bolt 31 of bolt lock 30 is bevelled and is pre-tensioned, protruding from the housing of the bolt lock 30, by a spring (not illustrated), so that by shutting the door the door is automatically locked, when the door opener is closed. Unlocking will only be possible then by opening the door opener 37.
  • day and night lock 32 is modified in the illustrated embodiment, as it does not comprise a bolt.
  • the bolt 35 also bevelled, is retractable against the spring load into the housing of the day and night lock with a key by means of a cilinder to be provided in the opening 34.
  • a key day and night lock 32 can be opened from two sides, therefore, even when the electric opener 38 is closed.
  • Said opening is also possible by means of a latch fitting into the opening 33, but according to the invention said latch is only provided at one side to make the first door accessible into the direction of access from the intermediate room to the first room when the door opener 37 is open and the door opener 38 is closed, as explained hereinabove with reference to the situations I,III and V.
  • the same principle applies to the second door.
  • the inductive approach sensor 39 is a coil on an open core
  • a part (not illustrated) of magnetic material, preferably ferrite, is provided opposite that on plate 40.
  • the sensor 39 only responds to that when the distance between the permanently magnetic part and the sensor lies within a precisely determined narrow range of a magnitude of e.g. 1-2 mm.
  • the coil with open core of the inductive approach sensor is incorporated in an oscillator circuit with a circulating amplification or less than 1 for that purpose.
  • the quality factor Q of the oscillator circuit which works to a frequency of the magnitude of e.g. 30-40 kHz, changes.
  • the inductive approach sensor does not deliver a closing signal with a distance that is too large, nor with a distance that is too small, in that use is made of a level detector which responds to a small range of the level determined by the quality factor of the oscillator circuit, corresponding with the afore-mentioned range of the magnitude of 1-2 mm. Owing to this, according to the invention, the possibility of sabotage is removed.
  • inductive approach sensor is now preferred, also another inductive approach sensor of a different type may be chosen, viz. one that responds to the material of the door or of the plate 40, e.g. steel and/or aluminium.
  • a type suitable for that is the approach sensor available under the trade name NAMUR type 12-4.
  • approach sensors applied in welding robots are usable.
  • the signal of the inductive approach sensor is not exclusively relied on according to the invention, but also the signal of the bolt switch is involved for the closing criterion.
  • a signal from either one of the approach sensor and the bolt switch is sufficient to make the system conclude that the door is open, and because in fact it concerns logical signals here the signals from both the approach sensor and the bolt switch are required to make the system conclude that the door is indeed closed, i.e. shut and that the bolt is in the closed opener, 35 and 38 respectively.
  • the OP-function is used instead of the EN-function, i.e. the door being open is detected when either a signal from the approach sensor 39, or a signal from the bolt switch, or a signal from both is received.
  • Fig 3 illustrates, with the reference numbers 17 and 18, a closure sensor means, which closure sensor means in this case comprises the approach sensor 39 and a bolt switch, whilst the OF-signal of the lock sensor means 17 and 18 is fed to the inverting input of the differential amplifier 5 and 7 respectively, whereby closure sensor means 17 is related to the second door and closure sensor means 18 is related to the first door, therefore.
  • Reference numbers 15 and 16 indicate adjusting means for adjusting a reference voltage to be fed to the non-inverting terminal of the differential amplifiers 5 and 7 respectively.
  • the distance between the permanently magnetic part and a head side of the coil of the inductive approach sensor can be set or adjusted, as the case may be, electronically (and this is important) instead of mechanically.
  • the output of the differential amplifiers 5 and 7 is connected to the light-emitting diodes 25 and 26 respectively, for lighting up when the second and the first door respectively are closed.
  • the output of the differential amplifiers 5 and 7 is connected to the non-inverting input of differential amplifier 6 and 8 respectively, whereby the inverting input of differential amplifier 6 is connected to the output of differential amplifier 8, the inverting input of which is connected to the output of differential amplifier 6.
  • a further input of the differential amplifiers 6 and 8 is connected to a control circuit 22-24.
  • the output of the differential amplifiers 6 and 8 is connected, via driving means 11 and 13 respectively, to door opener 1(37), which is normally open during operation (situations I, III and V), of the first door and normally open door opener 3(37) of the second door.
  • the light emitting diodes 27 and 28 indicate the first and the second door respectively being open.
  • the light-emitting diodes 27 and 28 are connected to a timer 19 (NE 555) for intermittently lighting up, preferably red, the light-emitting diodes 27 and 28.
  • the light-emitting diodes 25 and 26 for the first and the second door respectively being closed preferably emit green light.
  • the control circuit 22-24 comprises three switches or switching means, in the illustrated embodiment in particular the emergency switch 24 already mentioned before, time switch means 23 and operating switch means 22.
  • the emergency switch 24 and the switch means 22 and 23 are open, making a light-emitting diode 29, emitting e.g. green light, light up.
  • a light-emitting diode 29 ⁇ emitting e.g. red light, will light up.
  • the output of the control circuit 22-24 is also fed to the input of the differential amplifiers 6 and 8 in order to prevent, in case the safety device is out of operation, that the normally open door openers 37 close on the doors being opened.
  • the output of the differential amplifiers 6 and 8 therefor delivers a control signal to the control means 11 and 13 respectively when a respective door is opened, through which the locking means 1,3 (30, 37) respectively are locked or door openers 37 are closed through which the respective door is locked. Furthermore the light-emitting diodes 27 and 28 respectively are triggered in that case to go off and on intermittently.
  • differential amplifiers or operational amplifiers are connected in a flip-flop circuit to exclude both doors being locked simultaneously.
  • a switch 20 or 21 for unlocking the normally locked locking means of the first and second door respectively will result in the first and second door respectively being automatically locked.
  • the input of the driving means 11 and 13 is connected, via switch 20 and 21 respectively, to differential amplifiers or operational amplifiers 9 and 10 respectively, again connected in a flip-flop circuit, which in their turn are connected to driving means 12 and 14 for driving the normally locked locking means of the first and second door respectively.
  • the switch section 22-24 is connected to said driving means 12 and 14 in such a manner that when the safety device is put out of operation the normally locked locking means 2 and 4 will be unlocked.
  • the normally open locking means (30, 37 in fig 2) is locked through the control action of the electronic control means and the normally locked locking means (32, 38 in fig 2) are locked.
