Method of configuration of an electrical motorised lock and electrical lock for carrying out said method.

0001The invention relates to the field of electric locks. It relates to in particular a method for configuring an electric lock Motorised defined by the preamble of claim 1. It relates to more state detecting method of a lock according to the configured above method. It finally relates to an electric lock and a motorization device and control of a motorized cylinder being transforming a manual lock electric lock, the lock and device for carrying out the method according to the invention.

0002motorized cylinder electric locks comprise a frame which supports and guides the bolt. This bolt is capable of moving a extreme position called "unlocked" in which the bolt is retracted in the frame to extreme position called "locked" in which the bolt protruding from the frame. The distance between these two positions is the throw of the bolt. They also include a cylinder capable to be rotated by a motor via a reduction gear and driving the bolt by means of a key bit.

0003To go from one extreme position of the bolt to another, it can be necessary that the cylinder makes several revolutions. In general, the travel of bolt is covered by one or two cylinder towers.

0004It is known to control by a logic processing unit rotation the electric motor driving the cylinder. The cylinder may also be manually operable.

0005The motorized roller may be installed on one side or the other of the lock so that the lock can be mounted on a door opening to the right or left opening and / or on a door opening inward or outward opening.

0006This motorized cylinder and its control means can be designed and implemented by the lock manufacturer, but can also be attached to an existing lock to replace a device purely manual. In this case, no sensor has been provided on the frame the lock or the bolt for determining the locked state or unlocked from the lock or the direction of movement of the bolt.

0007Depending on which side was mounted cylinder and the type of covers which the lock is installed, rotation of the cylinder in one direction determined thus produces a movement of the bolt in the direction of the position "locked" or in the direction of the "unlocked" position bolt.

0008These locks are further controlled by means of buttons command, which may include two buttons, one whose actuation causes the movement of the bolt in the direction of the position "Locked" and one whose actuation causes displacement of bolt in the direction of the "unlocked" position of the bolt. They can further include a screen indicating the position of the bolt. Finally, the unit control logic may include special provisions related direction of movement of the bolt, for example limit the force in the direction locking.

0009Preferably, the control buttons are arranged on a portable remote control, for example radio frequency. For some simplicity, some remotes contain only button.

0010In the latter case, the output order may consist only of an control state change, without the need to distinguish a lock command and an unlock command.

0011Even when the control device simply sends an order of change of state, it is still necessary to have knowledge of the locked or unlocked state of the lock after a movement of the cylinder. Indeed, if the motor cylinder is radio by example, it is useful that the control device can communicate this broadcast information, eg to an alarm center.

0012This results in the need to configure the lock at the time of installation on a door so that there is good correlation between the operated control button and movement of the bolt in the lock and / or there is good agreement between the true position of the bolt and the indication of the position of the bolt.

0013In the prior art, it is known to satisfy this need by switching manually, during installation of the lock, an electric inverter to a position called "door opening right" or to a position called "door opening to the left", as the door opens to the right or left. Such an embodiment of the present drawbacks. First, we must recognize the type of door, the other, this rule applies only to a door opening inwards provided, as is generally the case, a lock with a cylinder motor disposed within. Nevertheless, a door can open to outside and, in this case, reverse the rule, unless the cylinder motor is disposed outside. Finally, the switch position is difficult to read because, in general, it is very small in order not increasing the size of the cylinder motorization device.

0014With a lock as described above, it is necessary identify the type of door, its opening direction and the cylinder position motorized. After identifying these parameters, you must switch or not the electrical inverter to enable a button press driven opening control a movement of the bolt in the meaning of the "unlocked" position of the bolt. The whole procedure is source of discomfort and errors.

0015The object of the invention is to provide a configuration method electric lock that overcomes the drawbacks cited and having a improvement over known prior art methods. In particular the invention provides a simple configuration process does need not analyze the different characteristics of the door to deduce the position of a power inverter.

0025Figure 4 is a diagram of the electric control of the lock.

0026Figures 5 to 12 are front views of the lock in which the bolt and the cylinder are represented in different positions occupied during the configuration process of the invention.

0027Figure 13 illustrates the problem solved by the invention.

002814 is a flowchart of a preferred embodiment of the method of the invention.

0029The electric lock 1 shown in Figures 1 to 3 comprises mainly a frame 2 in which a bolt 3 is likely to be moved in translation under the action of a cylinder 5. The lock is intended to equip a door of a building.

0030The cylinder 5 can be rotated manually by through an action exerted on a door knob or 15 electrically by the action of an electric motor 13 transmitted by a gear 14. In Figure 2, the motorized cylinder is also shown in phantom to illustrate its installation on the other side of the lock.

0031The cylinder 5 comprises at one of its ends a cylindrical key bit 6 fixed eccentrically. A locking part 4 of the position the bolt has in its lower part two cylindrical notches 7a and 7b, for engaging the blade. This piece of Lock 4 is linked to the bolt by a vertical sliding connection materialized by a 9-groove in the room 4 cooperating with two pins arranged one above the other and secured to the bolt. The locking piece also has, in its upper part a cutout 11 having three notches 28 intended to cooperate with a pin 12 secured to the lock frame. A spring 8-shaped blade attached to the locking piece bears on the lock frame for recall the locking piece in a low position in which the pin 12 is in contact with one of the notches 28.

0032The cylinder also comprises a cam 17 having a boss 27 allowing to act, in certain positions of the cylinder, on two contacts electric 18 and 19 angularly offset with respect to one another. In certain positions of the cylinder, the boss 27 acts simultaneously the two electrical contacts 18 and 19. In other positions cylinder, the boss 27 acts only on one of the electrical contacts 18 and 19. And finally, even in the different cylinder positions, the boss 27 acts on any of the contacts. sequences actuating electrical contacts 18 and 19 allow determine the direction of rotation of the cylinder and determining the magnitude cylinder rotational movements.

0033The lock shown also comprises two electrical contacts 38 and 39 related to the frame of the lock. The bolt acts on these following contacts the position he occupies. In the position in which it is shown in Figure 5, it acts on the two contacts. In the position in which it is shown in Figure 8, it only acts on the contact 39. In the position in which it is shown in Figure 10, it acts on any contacts. One of these contacts allows activating sequence by therefore determine the direction of bolt movement. For determine the direction of movement of the bolt from a motion one of lower amplitude, it is also possible, on the bolt at the contacts 38 and 39, holes causing sequences operating more frequent contact.

0034The electrical contacts 18, 19, 38 and 39 may be constituted by example of switches, reed switches, elements photocells or Hall effect sensors. These contacts, and in particular those relating to the movement of the bolt, only involved in some embodiments of the process. The lock can also be of CP sensor effort or motor supply current, connected to the unit processing logic 20 and to detect the end positions of throw of the bolt by stress analysis or transmission analysis current motor.

0035As shown in Figure 4, the electric motor 13 is controlled by a logic processing unit 20 fed by a supply 26 and connected to the electrical contacts 18 and 19 to a control 22 comprising an unlocking button of the lock 23 and a locking button of the lock and a screen 21 of display 25 with two witnesses indicating the position of the bolt of the lock.

0036Pressing the locking button 23, respectively the release button 24 of the control, After setting allows a lock controlling the rotation of electric motor 13 in the direction causing movement of the bolt towards its position "unlocked" PO, respectively, in the sense causing movement of the bolt into position "locked" PF. The control 22 is preferably a portable remote control. The connection between the control and logic processing unit is then performed by a wireless communication means, for example radio frequencies. If the witnesses are deported on the housing portable remote control, then the communication link is bidirectional.

0037The logic processing unit can also communicate so unidirectionally or bidirectionally with a central alarm, by example to inform the locked or unlocked status of the lock.

0038Figure 13 illustrates the problem solved by the invention. The trends motor power supply 13 are referenced M1 and M2. E.g., fashion M1 is a polarity +/- while the mode M2 corresponds to a polarity - / +. We denote the unpowered state of the engine by M0. Both directions of bolt movement are referenced SO (Unlock) and SF (lock).

0039According to the mounting of the motor cylinder in the lock and the lock on the door, one is either in the configuration of the association between A1 (M1, M2 and SW, SF) or in the A2 configuration.

0040The invention identifies the installation configuration. Otherwise, the invention allows to choose between the R1 and R2 relationship relationship, these relations linking CO unlocking control orders or CF locking the motor power supply modes M1 and M2.

0041The invention also applies to the case of a motorized cylinder for which the logic processing unit only receive control commands EC state change from the remote control, which in Figure is symbolized by a flip-flop operating in divider by 2. In this cases, identification of the A1 association or the association is to A2 less used for the detection of PO and PF positions even in absence of specific sensors for this purpose.

0042Indeed, such sensors would necessarily be disposed on the frame the lock, and not on the driven cylinder can be attached thereto, which is a drawback if the frame was not designed for a automation of the lock.

0043It will be noted that it is equivalent to speak of M1 power mode, M2 motor or sense of rotation C1, C2 of the cylinder driven by the engine, since the kinematic relationship between motor and cylinder is fixed by construction, contrary to that between the motor and movement of bolt.

0044Thus, knowledge of the A1 or A2 combination allows Knowing the direction of movement of the bolt either during a maneuver electrically controlled, or even during a maneuver controlled manually if the motor cylinder is equipped with means to know the direction of rotation of the cylinder.

004514 illustrates an embodiment of the configuration method of the lock, or the motorized cylinder on an existing lock, with a learning procedure. This preferred embodiment is also illustrated by Figures 5 to 11.

0046As shown throughout the Figures 5 to 11, the rotation of the cylinder 5 in clockwise enables the translation of the bolt into position 3 projecting from said lock "locked" position. Indeed, when the rotation of the cylinder, the blade 6 comes into contact with one of notches 7a or 7b and raises the locking member 4 against the action of 8. This spring uprising releases the pin 12 from its notch in the top 11. The cutting blade 6 in its movement circular driven by the displacement of the locking piece, the bolt 3 in translation relative to the frame 2. When the blade has passed its high point, the locking piece descends under the action of spring 8 until the pin 12 comes into contact with a notch in the cutout 11. In this position, shown in Figure 8, the sliding the bolt is again prohibited.

0047The lock described above allows the implementation of a first embodiment of the learning process described by configuration below. The steps designated by the letter S followed by a number are Referring to FIG 14.

0048In a first step S1, the installer leads by action Manual on the knob 15 connected to the cylinder, the bolt in its unlocked extreme initial position PO as shown in Figure 12. The cylinder is then, as shown in this figure, in a extreme position in which its rotation is prohibited in the sense trigonometric due to the contact between the locking piece 4 and the bit 6. The initial position may also be the position shown in Figure 5. This position does not correspond to a stop position blocking the cylinder rotation stroke. It corresponds to a position sensitive manually because the movement of the blade causes deformation of the spring 8. This position may in particular allow remove the key in the case of a key cylinder.

0049In a second step S2, the installer puts the electric lock in a programming mode. This passage is in programming mode for example by a prolonged supporting action on the two buttons order 23 and 24.

0050In a third step S3, the installer manually actuates cylinder in rotation in a direction corresponding to the locking bolt SF is to say, here clockwise. This action results in the sliding of the bolt relative to the frame as shown in Figures 5 to 8. During this action, the boss 27 of the cam 17 actuates successively electrical contact 18 and the electrical contact 19. If the cylinder was mounted on the other side of the frame, this action lock would need a maneuver of the installer in the direction anticlockwise the cylinder.

0051The actuation cylinder manual is continued until the direction of rotation of the cylinder allowing the movement of the bolt has been recognized, for example as a result of a drive sequence of Contacts 18 and 19, which occurs in step S4.

0052According to the sense recognized by the logic processing unit, it is thus in the case of A1 combination or in the case of A2 association. The determination is made in step S5. In the first case, the logic unit processing proceeds to step S51 for supplying the engine according to the M2 mode, confirming the manual action being locked. AT step S52, it also saves the R1 relationship as valid, in order can later meet separate commands. In the second case, the logical processing unit proceeds to step S53 the feed motor according to the mode M1, confirming the action Manual current lock. then R2 is recorded as valid to step S54. We denote the steps S5, S51-S54 under the term Generic fifth step.

0053At the sixth step S6, the motor power supply is maintained until the bolt reaches the end of rotational travel as shown in 11.

0054When the limit switch or stop is reached, it goes to step S7 inversion, by the logic processing unit, the feed direction motor which drives this time the cylinder in the direction causing SO unlocking the bolt.

0055This power is maintained in step S8 to reach the other end run or stop. The logic processing unit uses the whole stage back at regular speed to count the number of revolutions NT carried by the cylinder, for example by means of contacts 18 and 19.

0056Once the limit switch reached, in step S9, the logic unit treatment cuts the motor supply (M0 State), saves the state PO unlocked position of the bolt and records the value of numbers NT revolutions of the cylinder between two extreme positions. The output mode configuration here is automatic at the end of step S9.

0057The lock will be configured. It can then be used. The advantage of this embodiment is that it is very intuitive for the installer.

0058In the process described above, the initial position of the bolt is "Unlocked" position, however, the process could also be executed starting from its "locked" position or another position special.

0059Numerous variants may be used. For example step S2 can be activated by the act of putting a lock power first time. This feature will be inhibited when the output of programming. The steps S51 and S53 are not essential, but give more comfort to the installer and allow confirm that the logic processing unit lock has "understood". Step S7 and S8 are not essential but also give more comfort to the user. If step S7 is not integrated in the mode executing, then counting the number of revolutions is effected NT during the locking action.

0060We see in Figure 13 that the R1 or R2 relations are introduced as valid relationship that during the procedure learning, which means that as long as the learning has not been Instead, the logic processing unit does not obey the orders or CO CF. It is also conceivable that a relationship has been introduced at the manufacture of the product, and the effect of learning is either maintain this relationship, or replace it with another relationship. We can also provide that the CA enable control to be used as reverse command with a pre-stored relationship.

0061The lock described also allows the implementation of a second embodiment of the learning process described by configuration below.

0062In a first step, we enter a programming mode.

0063In a second step, drives the cylinder 5, through action Manual on the knob 15 connected to the cylinder or by pressing a pushbuttons which causes rotation of the motor in a direction or the other until a movement of the bolt.

0064During this second step the direction of rotation of the cylinder 5 and the direction movement of the bolt 3 are identified by the logic processing unit 20. These identifications direction of movement and rotation are analysis carried out by contact of the activating sequences power 18, 19 and 38, 39.

0065It is thus determined and stored the meaning of in a following step rotation of the motor for moving the bolt to its position "Locked" and to its "unlocked" position.

0066In a next step, it exits the programming mode.

0067The lock is then configured and ready to use. As mentioned, the disadvantage of this embodiment is that it requires the movement of the bolt recognition means.

0068The invention is described in connection with a lock type of lock. She is applicable to any other type of lock and to any type of cylinder motorized, including cylinder Euro profile cylinder or round profile as described in EP 0,276,037.

0069The logic processing unit can cut the motor supply when excess torque is detected. We can build on the stop detection analysis, for example of the motor current for a variant of the above method does not involve contact 38 and 39 for analyzing the movement of the bolt.

0070When starting from a predetermined position, for example position PO unlocked, and that CA activates a start button, simply the logic processing unit supplies the motor in a mode predetermined, eg M1 mode. If a stop is detected immediately is that the combination cylinder - corresponds to the bolt Configuration A1. Otherwise, it corresponds to the configuration A2.

0071After configuration, pressing the button 24 control closure triggers the electric motor power to move the bolt into its "locked" position and pressing the button 23 opening command triggers the supply of the electric motor to move the bolt to its "unlocked" position. Food the motor is maintained for a certain time or until a number of cylinder revolutions has been detected by the contacts.
