Definitions

  • the invention relates to a barrel provided with a rotor equipped with at least one keyway, a stator equipped with a cylindrical sleeve in which the rotor is received, and a tapped hole for fixing the barrel to a lock with a screw and through which passes a plane perpendicular to the axis of rotation of the rotor, said plane sharing the stator in a first portion containing the one or one of the key paths, said outer portion, and a second part, called inner part.
  • a common technique used by burglars is to smash the barrel at its weak point, that is to say at the recess provided for the rotation of the bit. This rather narrow portion of the barrel is further weakened by the presence of a threaded hole for receiving the screw for fixing the barrel in the lock.
  • the outside of the barrel protrudes more than 3 mm from the door, it offers a good grip and the outside of the barrel can be easily torn off.
  • a strong pull is already enough to tear the barrel of its housing, thus leaving access to the bolt of the door.
  • it can protect the outer face of the barrel by a rosette or a pad, which however can be easily ripped off.
  • Another mode of operation consists in striking the outer face of the barrel with a sharp blow, which causes it to break at the recess of the blade. Once the barrel broken in half, just take out its outer portion to have access to the device for actuating the bolt.
  • Another solution is to place in the room to be protected presence detectors that trigger an alarm when a person passes in front. This assumes, however, that the alarm is triggered, which is generally not the case when people are in the dwelling. Thus, a door opening detector will not sound if someone opens the door while the alarm is off. After having smashed the barrel, which does not make much noise, a burglar can easily get into the housing without attracting the attention of its otherwise occupied inhabitants.
  • Document is known WO 2009/093 090 A1 an anti-burglary device consisting of an electric loop which is interrupted in case of tearing of the barrel.
  • the monitoring device consists in particular of two insulating rings each threaded at one end of the cylinder. Each ring is provided with a sensor consisting of a threaded hole in which can penetrate a conductive threaded rod. Each threaded rod is connected via a cable to a connection itself connected directly or indirectly to an alarm unit.
  • the rings are threaded on the ends of the cylinder and the threaded rods are screwed until their pointed end is in contact with the body of the cylinder.
  • a closed circuit is thus formed which starts from the alarm unit, passes through the first connection, the first cable, the first threaded rod, passes through the body of the cylinder, exits through the second threaded rod, the second cable, the second connection to return to the alarm unit. If part of the cylinder is removed, the circuit opens and the alarm can be triggered.
  • This device is particularly complicated to mount. If the ring is mounted on a protruding part of the barrel, it must be hidden behind a rose that can be easily torn off. If the barrel does not protrude from the door, the ring must be mounted in a recess made in the door, which requires that it is full. In addition, the contacts between the threaded rods and the barrel may oxidize or relax after the many shakes experienced by the barrel when opening and closing the door. In this case, the device will trigger a false alarm.
  • the document DE 103 25 731 A1 evokes very vaguely the possibility of placing a control device flat on a cylinder.
  • the device would consist of two conductors arranged in an insulating envelope and separated from one another by an insulator.
  • the insulation is supposed to leave the envelope in case of rupture or deformation of the cylinder, so that nothing would prevent the two drivers to come into contact and trigger the alarm.
  • the device is very sensitive to the shakes suffered by the barrel when the door slams. The insulation may leave your home accidentally causing a false alarm. If, on the contrary, it is too well fixed not to fall easily, it may not escape when the cylinder is damaged.
  • the document DE 198 33 834 A1 very briefly describes an anti-theft device.
  • An electric cable is placed in a PVC tube.
  • the electric cable cooperates with a relay.
  • the screw to fix the cylinder in the door passes through this PVC tube.
  • the relay triggers an alarm.
  • This solution does not seem very reliable in many ways. Firstly, the wire passes into a PVC tube which must receive the barrel fixing screw. It is likely that the wire will be damaged when screwing the screw triggering an alarm as soon as the cylinder is put in place. In addition, the presence of the PVC tube does not allow proper screwing and fixing the barrel is doubtful. Finally, pulling the barrel does not necessarily cause tearing of the fastening screw. So the wire may not be torn off and the alarm will not be triggered.
  • the document DE 92 10 237 U1 proposes an anti-theft device for a car barrel. It consists of a loop of a coated wire placed either inside the rotor or inside the stator, this loop being connected to an analysis circuit. If a thief tries to pierce the cylinder with a wick, it will damage the loop and trigger an alarm.
  • the document does not specifically indicate where and how to place the mouth on the rotor or on the stator. It is only indicated in the case of mounting on the stator that the loop must closely surround the rotor. In any case, the wire can not pass in a circular channel made in the stator, because such a channel would not be feasible. It must therefore be concluded that it is placed at the interface between the rotor and the stator.
  • the document gives no concrete indication of how the loop is connected to the electronic circuit. If the barrel is torn in the traditional way, the wire will not be damaged and no alarm will be triggered.
  • the object of the invention is therefore to inform the occupants of an attempted break-in on the barrel and develop a barrel provided with an anti-burglar device that is simple to mount, robust and insensitive to the shaking suffered by the door .
  • Another object of the invention is that the anti-burglary device is of high reliability.
  • the barrel further comprises an anti-burglary device consisting of an insulated electrical wire fixed to the stator, an electronic circuit and means for transmitting an alarm signal.
  • the two ends of the electric wire are connected to the electronic circuit forming, between its two ends, a loop which is hooked by means of attachment to the outside of the barrel so that in the assembled state in a lock, the electric wire pulls out at the moment when the outer part of the barrel is extracted from its housing.
  • the anti-tampering device of the invention emits a signal informing the occupants or a supervisory agent of the partial extraction of the barrel before the burglar has had time. to enter the dwelling.
  • the hooking of the wire can be achieved for example by passing through a wire passage made in the outer part of the barrel and in which can pass the loop of the wire. Rather than a passage, it can provide a notch made in the outer part of the barrel and forming a kind of hook in which the loop of the electric wire can be retained. If the outside of the barrel is torn off, the wire breaks breaking the electrical circuit.
  • a groove is formed on each of the lateral faces of the barrel to guide the strands of the loop of the electric wire from the attachment means to the inside of the barrel, preferably to the face of the barrel opposite to the outer portion. It is preferable that the strands of the loop of the electrical wire are glued at least partially in one or both grooves.
  • the electronic circuit can be placed for example on the inner face of the door while being inaccessible to the burglar from the outside.
  • the alarm signal can be processed in different ways.
  • the simplest is to provide the electronic circuit of a siren and / or a visual alarm and means for triggering the siren and / or the visual alarm when the outer portion of the barrel is not in its housing. However, it may be better to place the siren and / or the visual alarm elsewhere than at the door.
  • the electronic circuit is provided with a radio transmitter.
  • the anti-theft device comprises in in addition to a radio receiver with a siren and / or a visual alarm and means for triggering the siren and / or visual alarm when the outer portion of the barrel is not in its housing.
  • the radio receiver with siren and visual alarm can be placed in a more strategic location of the housing, or even be designed to be carried by the occupant during his movements in his home, garden, cellar or attic.
  • the electronic circuit may be provided with a GSM transmitter capable of sending telephone calls and / or short messages. It may also be equipped with a WIFI transmitter capable of generating e-mails and transmitting them to a WIFI terminal connected to the Internet.
  • the electronic circuit can be placed in different places. In a first variant, it can be placed in the lock or on the door. It is also possible to house a portion of the electronic circuit on the barrel, preferably on the inside of the barrel. The electronic circuit is then provided with means for wirelessly transmitting the wire breaking information to means for transmitting the alarm signal located at a distance from the barrel. In this second embodiment, the barrel may be provided with a second wire passage, the first and the second wire passage being placed on either side of the plane of rupture. Similarly, it is preferable to place the part of the electronic circuit fixed to the barrel in one or more housings made on the lateral face or faces of the barrel.
  • the part of the electronic circuit placed on the barrel can be carried by several cards, part of which is placed on the first side face of the barrel and the other part is placed on the second side face of the barrel.
  • the different cards are preferably placed on the same side of the plane of rupture (P). Wiring passages may be provided to connect the cards together.
  • a rotor housed pivoting in a stator is locked in rotation by pins that can be moved by a suitable key by releasing the rotation of the rotor.
  • a key-lock cylinder as shown by way of example on Figures 1 to 4 .
  • Such a barrel is constituted by a stator (10) fixed to the lock (30) and a rotor (20) which, when rotating, drives in rotation a bit (21) which itself actuates the bolt of the lock.
  • the rotor has a slot called a key path (22) into which the key is inserted.
  • the stator is also provided with a series of housings which, when the cylinder is in the closed position, are aligned with the housing of the rotor.
  • the rotor housings and those of the stator are schematically represented in dashed lines on the figure 3 .
  • Counter-pins are placed in the stator housings. Springs push the cotter pins against the pins which are thus pushed into the key way. In the absence of a key, the counter-pins protrude from their housings and penetrate those of the rotor: they block the rotation of the rotor in the stator.
  • the pins have different heights.
  • the notches of the key repel more or less depending on their depth pins in the direction of the stator, thus pushing against the pins against the effect of the springs. If the notches of the key have the correct depth, the line of separation between the pin / cotter pin pairs aligns with the line of cut between the rotor and the stator: it is possible to rotate the rotor and the bit and to operate the bolt of the lock. On the other hand, if one of the notches does not have the desired depth, the pin does not push the pin back enough in the stator and the latter stays astride between the stator and the rotor.
  • a recess (14) is formed in the stator body at the end of the cylindrical sleeve (11). Furthermore, a tapped mounting hole (15) is formed in the core (13) above the recess (14) to accommodate the bit. This threaded hole is used to fix the cylinder in the lock with a screw.
