Definitions

  • the present invention relates to an electrical device for controlling the unlocking of a rotating shaft of a lock and the lock equipped with this device.
  • the invention applies to locks mounted in a door handle or in a closure loop of a controlled access container.
  • GB-B-2 230 550 discloses a strike with means for blocking the operation of a door stand comprising a pivoting lever and a locking finger of said lever. This finger is operated by a plate provided to cooperate with an electromagnet.
  • a slope is provided on the lever and the finger is equipped with a roller which rolls on the slope.
  • the door can still open.
  • the rotational movement of the rotating shaft causes the movement of the striker
  • the rotational movement of the rotating shaft does not cause the movement of the striker. It is found that according to this arrangement, the rotation of the rotating shaft is still possible so that the user does not know whether or not to open the door. Thus he can actuate the handle several times, and possibly deteriorate it, before realizing that he is not authorized to open the door.
  • the electromagnetic means are of the plunger type, so that there are parts that slide relative to each other necessarily generating friction that automatically induce premature wear and significant power consumption.
  • the device according to the present invention is quite different. It includes electromagnetic means that locks and unlocks a rotating shaft.
  • This device is simple and therefore reliable. Moreover, it requires a very small amount of current at each operation so that the operating life of the device is increased for the same energy reserve which is necessarily a battery when the device is autonomous.
  • the overall dimensions of the handle or the loop that uses this device is reduced, which facilitates its integration into a plate of small width because this parameter is particularly restrictive, and acceptable thickness while allowing to respect standard fixing distances. This advantage is particularly valuable when it comes to replacing existing handles.
  • the invention relates to a device for controlling the rotational movement of a rotating shaft of a lock, comprising electromagnetic means provided for receiving an electric pulse that can be emitted by means following the detection of signs. identification and acting on mechanical means, characterized in that the electromagnetic means are in the form of a current-emitting sucker and in that the mechanical means are capable of occupying two positions under the action of the means electromagnetic, a first so-called locked position in which they immobilize in rotation the rotating shaft and a second so-called unlocked position in which they allow the rotational movement of the rotating shaft, and comprise a magnetic counterplate provided to cooperate with the suction cup between two positions, one stuck against the suction cup when it is in its magnetic field and the other separated from the suction cup when it is out of the magnetic field.
  • the suction cup more particularly comprises a permanent magnet and a circuit for generating a magnetic field canceling at least a portion of the magnetic field of the permanent magnet upon receipt of the electrical pulse.
  • the mechanical means comprise rearming means capable of reintroducing the counter-plate into the magnetic field, preferably in the form of a lever secured to said counterplate and a movable strut between a first position corresponding to the locked position of the rotating shaft, and a second position corresponding to the unlocked position of the rotating shaft.
  • the reset lever comprises a flat surface, coming from manufacture, which constitutes the backplate.
  • the rearming lever comprises a lug released from the strut when the counterplate is in the first position and rest against the strut when the counterplate is in the second position.
  • the mechanical means comprise a follower with a finger and the reset lever comprises a cam adapted to receive the finger and ensure the lifting of the lever.
  • This follower comprises at least one offset profile conjugate that of the free end of the strut to cooperate in the locking position, providing a free maneuver game of small amplitude.
  • These mechanical means comprise elastic return means disposed between the strut and the reset lever.
  • the device comprises a cassette supporting at least the mechanical locking / unlocking means and the current-issuing suction cup of the electromagnetic unlocking means.
  • the invention also covers the door handle equipped with the preceding device and which further comprises a second follower provided with a driving pin of the first follower, itself provided with a light for receiving said pin, this second follower being secured to the inner stand and having at least one slope provided to bring the strut from the first locked position to the second unlocked position.
  • the light of the second follower is of such dimensions that the first follower is driven when the strut is released from the first follower.
  • FIGS 1 and 2 there is shown a door handle 10 with a casing 11 receiving a cassette 12 on which is reported a source 14 of energy with an electronic circuit 16 recognition and control, electromagnetic means 18 locking / Unlocking as well as mechanical means 20 for locking / unlocking the rotating shaft of a lock, the assembly being covered by a so-called freeness plate 22.
  • the housing 11 is intended to be fixed to the door by two holes 24, standard spacing.
  • the source 14 of electrical energy is a battery 26.
  • the electronic recognition and control circuit 16 is connected by a cable 28 to other members (not shown) which are not of direct interest to the invention, namely a reader card or chip or any other means of recognition and identification and a vibrator intended to emit a its particular to confirm the good or bad maneuvers of the user.
  • Another cable 30 provides power to the electromagnetic means 18.
  • the electromagnetic locking / unlocking means 18 comprise a electromagnetic suction cup 32 with current emission, designed to receive a metal counterplate 34, magnetic, capable of being held in a first position glued against the suction cup 32 and to be released into a second position.
  • This type of suction cup comprises a permanent magnet of high power which ensures a constant magnetic force sufficient to maintain the counterplate, or any other metallic and magnetic plane element, glued as soon as it is in the zone of attraction. If a current is circulated in an associated winding disposed in said suction cup, it is possible to generate an electromagnetic field whose intensity is calculated to cancel at least in part, the permanent magnetic force generated by the magnet, so that the against the plate is subject only to the permanent magnetic force minus the electromagnetic force generated during the emission of a current pulse.
  • the mechanical locking / unlocking means comprise the counter plate 34 which receives at its lower part a resetting lever 36 which is articulated relative to the cassette by means of an axis 38, with a limited angular movement. It is alternatively noted that the lever could be shaped so that it has a surface similar to that of the against-plate thus allowing the removal of this against-plate.
  • a seal 40, ring makes it possible to make up any possible defects of parallelism between the counterplate and said lever and this is particularly the interest of this against-plate.
  • the connection between the backplate and the suction cup provides a certain angular displacement, so that the force of the permanent magnet is exerted on the entire surface of the backplate by self-orientation thereof.
  • This lever means 20 mechanical locking / unlocking has a lug 42 which will determine the utility during the description of the operation.
  • the lever carries at its end, a reset cam 44 belonging to the resetting means.
  • the joint is reduced to its simplest expression since the heel of the strut is simply supported on the bottom of a housing 48 whose walls provide guidance.
  • a return spring 49 is interposed between the reset lever and the strut.
  • the mechanical locking / unlocking means 20 further comprise a follower 50, having substantially the shape of a disc, pivotally mounted about an axis 52.
  • This follower is provided at its center with a hole 54 of square section, provided to receive, in known manner a square axis of maneuver, said "square", itself driven by a crutch, visible in broken lines in Figure 3A. This square allows the drive of the rotating shaft of the lock.
  • This follower 50 is symmetrical and has a finger 56 oriented, in a stable position, along the vertical axis.
  • a recess 58 is provided on either side of this finger, also symmetrically, substantially at 90 °. Depending on the mounting opening on the right or on the left, the corresponding recess is able to cooperate with the free end of the strut 46, in the locked position as will be explained later.
  • FIGS. 3A to 3G the references of identical elements being shown in the various figures.
  • This very small rotation is permitted by a clearance formed between the free end of the strut 46 and the recess 58 corresponding whose follower 50 is provided.
  • This game allows the user to feel that the maneuver is possible but that a locking system prohibits a greater angular maneuver to open the door. This prevents the user from excessive force, imagining that the stand is stuck by a malfunction. In addition, it surely allows a repositioning of the strut in the recess of the follower.
  • the strut locks the mechanical means and more particularly the follower 50. Moreover, it is noted that in this position, the counter-plate is glued against the suction cup in the first position of reminder, the permanent magnet ensuring its full attraction.
  • the reset lever 40 integral with the counter-plate 34, is also in its first position so that the spring 49 is tensioned, the restoring force exerted being maximum.
  • the strut tends to be maintained in the first unlocking position even in case of shock actuation of the stand or in case of impact on the handle.
  • An electrical pulse is sent by the electronic means 16 to the pad 32 to cancel at least a portion of the attraction force of the permanent magnet. This negative effort is added to that of the spring.
  • the spring 49 which exerts a continuous traction between the counterplate 34 and the strut 46, causes the detachment of said counter plate of the suction cup.
  • the permanent magnet regains its power and emits its magnetic field in a normal way.
  • the counterplate, detached from the suction cup is at a gap distance that is too great for the backplate to be recalled, especially since said backplate is still subjected to the return force of the spring.
  • the lug 42 of the reset lever is remote from the strut in a stable position, so as to allow the detachment of the backplate and the angular movement of the lever even if the strut is blocked in the first position.
  • the system is unstable around the axis of rotation 38 of the reset lever.
  • the reset lever is closer to the finger 56 of the follower 50 while the strut is removed, allowing the rotation of the follower.
  • the strut is maintained in the second position with impossibility of blocking the rotation of the follower as shown in FIG. 3D.
  • FIG. 3F it can be seen that the cam is extended with a curvilinear profile corresponding to the movement of the end of the finger of the follower, this in order to avoid in all cases the passage of the finger behind the cam if the user, by an untimely maneuver, the kickstand exceeded the permitted angular rotation.
  • the striker, not shown, of the door is actuated at the opening, this in a known manner.
  • the return means of the striker ensure a return to stable position of the follower and the return to the initial position of the stand which is secured to it, as shown in Figure 3G.
  • the next position is that of the initial figure 2, thus showing the complete cycle.
  • the force stored by the spring is provided by the user when operating the stand, the suction pad only needing to unlock the mechanism by releasing the counterplate.
  • the operation of the crutches of the two handles is distinct.
  • the square is then made in two parts, one secured to the first follower as shown above and the other secured to a second follower 60, the two nuts 50 and 60 being rotated by a pin 62, as shown in FIG. Figure 4A.
  • the first follower 50 shown in broken lines, comprises for this purpose a curvilinear open light 64 which receives the pin 62.
  • This light of the first follower is of such a size as to allow an angular displacement of the second follower of a few degrees. before being driven by him, for example 10 °.
  • the second follower also comprises two slopes 66, only one of which is used, the second symmetrical being made for purposes of symmetry and reversibility.
  • the slope 66 concerned is arranged substantially with the same angular positioning as the recesses 58 of the first follower so as to cooperate with the free end of the strut 46.
  • this second follower is free of finger.
  • the mechanical means, the electromagnetic means and the means for emitting an electrical pulse on the same side of the door have been presented, but the means for emitting an electric pulse for example can be arranged on the side of the door. from the opposite door to the one that supports the rest of the device. This ease of arrangement allows to distribute the congestion if necessary.
  • FIGS. 5A to 5C show an arrangement of the same device applied for example to a lock of a container.
  • the corresponding block diagram shows how the device works in this arrangement.
  • FIG. 5A certain identical and previously described elements are found and the same references are assigned to these elements for a simplification of the drawings while the equivalent elements carry the same elements. same references increased by 100 and the new elements carry references from 200.
  • the follower 150 is modified by the presence of a toothing 210 in the lower part intended to mesh with the teeth of a rack 212.

  • An electrical pulse is sent by the electronic means to the suction cup 132 to cancel at least a portion of the attraction force of the permanent magnet. This negative effort is added to that of spring 149.
  • the spring 149 which exerts a continuous traction between the counterplate 134 and the strut 146, causes the detachment of said counter plate of the suction cup.
