Definitions

  • Some doors are equipped, at their periphery, with a system of linear bolts, the lateral translation movement of which allows their penetration into grooves made over the entire periphery of the jamb.
  • This movement is obtained by rotating 4 eccentrics placed at the 4 corners of said doors.
  • the object of the invention is to motorize the locking and unlocking of such doors so as to provide remote control.
  • the drive arm is mechanically and permanently linked to the blade operating cam.
  • the motor arm is rotated around the pivot by means of a nut moving linearly along an endless screw, itself rotated by means of 2 direct current electric motors whose shaft is directly linked to both ends of the worm.
  • the device is contained in a frame made of folded sheet steel which takes place in the thickness of the door leaf.
  • the device differs in the relative position of the two arms as well as in their mode of connection.
  • the drive arm made up of a tuba of square section, is of smaller section than the motor arm and can pass right through it since, in the part concerned, the motor arm is not consisting of only two steel blades located above and below the drive arm.
  • connection between the drive arm and the drive arm is carried out by means of the core of an electromagnet secured to the drive arm and placed inside thereof, which core, when the coil of the electromagnet is not supplied, penetrate a hole made in the motor arm under the effect of the spring which is in the electromagnet.
  • the core retracts and the two arms are separated, thus allowing the locking blades to be operated by means of any mechanical operating device without, however, being generated by the irreversibility of the drive arm drive worm.
  • the electromagnet is itself mounted inside a square tube which slides inside the drive arm. It is held in the advanced position by a compression spring placed on the side opposite the outlet from the core. This spring is threaded on a tube inside which can move the guide rod of the electromagnet core and which crosses the stop which keeps the spring in tension.
  • this mechanical locking system allows the erasure of the electromagnet and its core inside the drive arm, thereby separating the two arms.
  • the supply of the coil of the electromagnet realizes an electric disengagement while the displacement of the electromagnet backwards, realizes a mechanical disengagement.
  • the drive arm In use in "panic” mode, the drive arm consists of a “C” shaped profile inside which can penetrate, on one side only, the motor arm, itself produced in a square steel tube.
  • the drive arm is provided with a soft iron polar mass intended to be stuck on a retained electromagnet.
  • the drive arm is provided with a tension spring which tends to return it to the unlocked position while the electromagnet, when its coil is energized, tends to hold this spring in voltage.
  • the motor arm is perforated to allow the establishment of the nut and the passage of the worm screw ensuring its rotation.
  • the drive arm is itself perforated to allow the passage of the worm.
  • a second tension spring connects the two arms and is only tensioned when the motor arm, having brought the drive arm in the locked position until the electromagnet sticks, returns to the rear position to allow the device to be unlocked by cutting off the power supply to the electro-aiamnt coil.
  • the advantage of using two springs lies in the fact that the power required for tensioning said springs is twice lower for the same useful tension since one of the springs is tensioned by the drive arm for the locking operation while the other is tensioned when the motor arm returns.
  • FIG. 1 represents a plan view of the device, in its anti-intrusion version, in the position where the drive arm and the motor arm are separated.
  • Figure 2 shows a sectional elevation of the same device, in its same version, in the position where the two arms are linked by the core of the electromagnet.
  • Figure 3 shows a detail of the interior of the drive arm of the same device, in its same version.
  • Figure 4 shows the electrical diagram of this device in this version.
  • this device comprises a frame made of folded sheet metal on which are fixed the 2 direct current drive motors M1 and M2, the worm screw V, the pivot P around which the motor arm Bm revolves, the Be drive arm and Ca cam.
  • the limit switches I1 and I2 ensure that the motors stop automatically when the system is either fully open or completely closed.
  • Each of the 2 switches I1 and I2 is short-circuited by a diode (D1 and D2) which allows the motors to restart in the opposite direction.
  • the terminals of the limit switches I1 and I2 are accessible, thus making it possible to easily carry out remote signaling of the door locking state.
  • the door contact C will signal the complete closing of the door to allow the system to be operated only if the door is properly closed and prohibit it otherwise.
  • the two arms rotate one inside the other.
  • the drive arm Be is integral with the cam Ca for setting in motion the locking blades of the door.
  • the motor arm Bm is integral with the nut E driven by the worm screw V.
  • the core of the electromagnet A is kept out of its coil under the effect of a spring and penetrates into a hole made in the arm Bm thus ensuring a mechanical connection between the 2 arms Be and Bm.
  • the electromagnet A can then be de-energized.
  • the arm Be is provided with 2 metal parts T which have the purpose of guiding the core of the electromagnet A in the hole which is intended for it.
  • the electromagnet A fixed to the assembly constituted by the square section tube T1 and the cylindrical tube T2, slides inside the arm Be.
  • This assembly is retained in the advanced position by the action of the compression spring R1 by means of a stop Bu through which the tube T2 passes.
  • paneton of a lock barrel or of a follower rotating the pallet Pa will cause a traction on the cable Cb and will ensure the withdrawal of the assembly constituted by the electromagnet, its core and the tubes T1 and T2 thus separating the 2 arms Be and Bm.
  • the limit switches I1 and I2, the diodes D1 and D2 which short-circuit them, as well as the connection terminals of the motors, limit switches and the electromagnet A are soldered on a printed circuit. fixed to the bottom of the frame of the device.
  • FIG. 5 represents a plan view of the device in its anti-panic version in the "locking" position.
  • FIG. 6 represents an elevation-section of the same device, in the same version, in the "unlocking" position.
  • FIG. 7 represents the electrical diagram of the same device, in the same version, diagram on which the components are found soldered on the printed circuit attached to the frame as well as those which are soldered on the control printed circuit placed in the electrical cabinet located inside the room to be protected.
  • the motor arm Bm consists of a perforated steel tuba on which the bronze nut E is articulated and crossed by the worm screw V.
  • the arm Bm is articulated on the pivot P.
  • the arm Bm penetrates inside the drive arm Be and the protrusion Ex actuating the end-of-locking switch I1 crosses the soul of the arm Be by a light provided for this purpose.
  • the drive arm Be is also articulated on the pivot P.
  • the blade operating cam is welded to this arm.
  • a cylindrical polar mass Ma is fixed at its other end.
  • the spring R2 is fixed, the other end of which is fixed to the frame.
  • the Be arm actuates, in its locked position, the limit switch I3.
  • the spring R3 connects the ends of the 2 arms Be and Bm.
  • the limit switches I1, I2 and I3, the diode D2 as well as the connection terminals of the frame to the control cabinet are soldered on a single printed circuit fixed to the bottom of the frame.
  • the other electrical and electronic components are soldered on the same printed circuit placed outside the door in a control cabinet itself located inside the room to be protected.
  • the operation is as follows: Starting from the position where the two arms Be and Bm are in the unlocked position, the electrical connections being made and the circuits being supplied with direct current, provided that the contacts C and Ba are closed and the switch Ci is open, closing the fire detection contact Cd causes the coil of the relay Re1 to be supplied via the electronic time delay circuit consisting of the capacitor C1, the resistors r1, r2, r3, the diode D3 and the PNP type transistor TR1, a circuit which delivers across the coil of the relay Re1 a voltage pulse.
  • the relay Re1 goes up and its two reversing contacts operate, causing on the one hand the self-supply of the relay coil through the diode D4 and the limit switch I1 and on the other hand the supply of the motors M1 and M2 in the locking direction through the diode D2 which bypasses the limit switch I2 only in this direction.
  • the motors start simultaneously driving the two arms Bm and Be by bandaging the spring R2.
  • the electronic delay constituted by the capacitor C2, the resistors r7, r8, r9, the diode D5 and the NPN transistor TR3 would cause the fall of the relay Re1 and, consequently, the return of the arms Be and Bm to the unlocking position, leaving the motors blocked only for a short enough time so as not to cause their destruction or the melting of the supply protection fuse.
  • the fall in the delay Re1 causes the restarting in the opposite direction of the motors M1 and M2 as well as that of the arm Bm towards the unlocking position by bandaging the spring R3, and this until the arm Bm actuates the end switch stroke I2 which cuts the power supply to the motors M1 and M2 since the diode D2 is polarized in the opposite direction.
  • the motor arm Bm is in the unlocking position, thereby releasing the possible return of the arm Be from the irreversibility of the worm screw V.
  • the PNP transistors TR4 and TR5 their polarization resistors as well as the limit switch I3, actuated by the arm Be when it reaches the unlocking position, enable the indicator light V1 to be supplied only if the arm d the drive Be is in the locked position and that, simultaneously, the motor arm Bm is itself in the unlocked position.
  • This relay has a change-over contact and a normally closed contact which will operate simultaneously.
  • This relay will go up causing it to recharge and the restarting of the arm Bm towards the locking position until the unlocking position where, having actuated the limit switch I1, it will cause the relay Re1 to fall.
  • the second contact of the relay Re2 will have switched on the diode D6 which, when the relay Re1 falls, will prevent the motor arm from returning to the unlocked position.
  • the motor arm Bm blocks the return of the drive arm Be, even if the contact Ba of the panic bar is opened.
  • the opening of the fire detection contact Cd will cause the relay Re2 to fall, the short circuit of the diode D6, the power supply to the coil of the electromagnet Ae and therefore , the simultaneous return of the two arms Bm and Be to the unlocking position.
  • the PNP TR6 type transistor allows the supply of the LED V2 only if the arms Be and Bm are simultaneously in the locked position.
