Definitions

  • the present invention relates to a high security lock with double bolt and electric motor.
  • Security locks most often have a double bolt, which increases their solidity and their resistance to attempted break-ins. It is obviously advantageous that these bolts are quite long, however their length is generally limited by the dimensions imposed on the lock and the space occupied by the drive member.
  • the motor member is controlled by any appropriate means capable of triggering its supply in electric current, the latter advantageously being a direct current of low voltage.
  • any appropriate means capable of triggering its supply in electric current, the latter advantageously being a direct current of low voltage.
  • the means most frequently used to trigger its start-up mention may be made of digital combination commands and electronic remote controls.
  • the present invention aims to provide a double bolt lock with an electric motor which does not have any of the above drawbacks.
  • the gearmotor used in the lock according to the invention is advantageously mounted on the tail bolt perpendicularly to the latter, so that its size is reduced to a minimum, the tail bolt preferably affecting the approximate shape of an extended L at the end of its base by a finger perpendicular to said base, so as to roughly form a U of which one of the branches would be partially cut.
  • the gearmotor is connected, by means of an electrical connection, to the current source which supplies it, while its other end is secured to a toothed pinion meshing with a rack fixed on the plate of the lock.
  • the gearmotor is integral with the movement of the bolt, its reduced size allowing a greater displacement of the latter which can correlatively have a length greater than that of the bolts of known locks, its length may be between 25 and 35 mm.
  • the lock gearmotor according to the invention is advantageously associated with a locking system consisting of a plate secured to its axis of rotation mounted outside the bolt tail, and having at one of its ends a cutout allowing it to come into abutment against a part secured to the lock plate and having an appropriate relief in the form of a stair step.
  • the bolt in the closed position, the bolt is blocked by the locking system, while during the opening operation, the engine's reverse reaction torque due to friction causes it to pivot around its axis in the opposite direction, unlocking the locking system by releasing the plate from the stop.
  • a return spring fixed to the end of this plate adjacent to the stop allows to quickly rebalance the reverse reaction torque, the motor then initiating its rotation and moving the mobile assembly by meshing the pinion which is secured to it on the fixed rack to the turntable.
  • the engine stops allowing the return spring to bring the locking plate back to the rest position.
  • the two bolts of the lock according to the invention are advantageously cylindrical and mounted to rotate on themselves so as to be insciable.
  • They are preferably made of a special steel and guided by bronze bearings, this material reducing the friction forces enough for their operation to employ a minimum electrical power, less than 2 Watts.
  • the optical end-of-travel sensor arranged near the bolt tail can take the form of a fork between the branches of which a part secured to the tail bolt can move, this piece being external to the fork as long as the bolts are retracted, that is to say in the open position, and moving as the bolts exit until reaching between the fork legs, the optical sensor then instantly triggers the interruption of the supply current and the short-circuiting of the gearmotor, causing the stop snapshot of the bolt.
  • This device has the advantage of allowing precise positioning of the bolt during closing, avoiding any mechanical shock in the lock.
  • the key entry barrel mounted on the lock can be any security barrel of known type, associated with a key the end of which is flattened and has an oblong shape corresponding to that of the orifice in the plate. drive positioned between the barrel and the plate, so that the rotation of the key causes that of said plate.
  • the mechanical drive plate of the tail bolt can be maintained by the two cylindrical seats thanks to any suitable system such as an interlocking system for each cylindrical seat with a flat ring extending the plate in the middle.
  • This drive plate can have approximately a rectangular shape, the pins being arranged in the middle and at the edge of each of its short sides, which are advantageously in the shape of an arc of a circle.
  • the drive plate is arranged below the finger which extends said tail bolt and which is driven by one of the lugs projecting above the plate.
  • a door position sensor can advantageously complete the lock according to the invention, consisting of a dry contact reed relay positioned in the lock opposite a magnet placed in the keeper: when the door arrives in the closed position, the position sensor, actuated by the magnetic field created by the magnet, immediately triggers the starting of the motor with a view to the automatic closing of the lock.
  • the lock has two bolts 1 and 1 'mounted free in rotation on a bolt tail 2 which supports a geared motor 3 extended to one of its ends by an axis 4 secured to a pinion 5 meshing on a rack 6 fixed on the plate 7 of the lock, which has four fixing holes 30.
  • the plate 7 is provided, on the side of the bolts 1-1 ′, with a flange 7 ′ on which are fixed two bearings 8 and 8 ′ for guiding the bolts 1-1 ′.
  • the geared motor 3 is supplied with electric current by means of an electric wire 27 connected to a connector 11 which ensures the electrical connection of the lock, the electric wires arriving through a through hole 12.
  • the tail bolt 2 is extended, on the side opposite the bolts, by a finger 13 under the end of which is positioned a drive plate 14 affecting the approximate shape of a rectangle whose short sides are rounded and bear in the vicinity from their border two lugs 16 and 16 ′.
  • the plate 14 is extended on its two faces by two rings 17 centered in the middle and allowing its maintenance by two cylindrical bearing surfaces, not shown, extending the key entry barrel 15, provided in its center with an opening 18 for the passing the key.
  • the key entry barrel 15 is secured to a plate 19 fixed by means of screws 20 to a plate 21 secured to the plate 7 by screws 22.
  • the bolt tail 2 is extended by a part 23 roughly affecting the shape of a U and which, in the closed position, is positioned between the two branches of an infrared optical sensor 24 which is used to stop the travel of the bolts 1-1 ′ during the electric opening operation of the lock, the entry of the part 23 into its optical field triggering, by means of appropriate electrical connections, the stopping of the geared motor 3 and its short-circuiting.
  • a door position sensor 25 makes it possible to trigger the closing mechanism of the lock when the door is facing the strike, thanks to a reed dry contact relay which is then in the magnetic field of a magnet positioned in the spoils.
  • the locking plate 9 ′ mounted on the axis of the motor between the bolt tail 2 and the pinion 5 comes, in the closed position, into abutment against a stop 9, the return spring ensuring its maintenance in the rest position during an opening maneuver.
  • the bolt tail 2 terminated by the finger 13, is positioned slightly above the drive plate 14 provided with two lugs 16 and 16 ′ ensuring the displacement of the tail bolt 2 during a key maneuver.
  • the plate 14 is held by two cylindrical bearing surfaces 27 and 28 each enclosing two rings 17 which extend it in the middle, the two bearing surfaces 27 and 28 extending at its lower part the key entry barrel 15 secured to the plate 19 than four screws 20 secured to a plate 21 itself secured by four screws 22 to the plate 7.
  • the unlocking of the lock 9 can be observed during an opening operation of the lock, this unlocking being carried out by the pivoting of the axis 4 of the motor in the opposite direction, due to the reaction torque reverse of the motor due to friction.
  • the key inserted into the key barrel 15 and maneuvered in rotation causes the plate 14 to rotate, the lug 16 driving the pin 13 of the bolt tail 2, as shown in FIG. 4b.
  • the key returns the plate 14 to its initial position and the bolts 1 and 1 ′ are returned, as can be seen in FIG. 4c.
  • the lug 16 is again in position for an opening operation, while the lug 16 ′ is in position for a closing operation.
  • the lock can then be operated either mechanically or electrically, which constitutes an appreciable advantage compared to known devices.
