  • the actuation link includes a connecting rod 12 which connects the solenoid rod 11 to a pivotal link 13 which includes a toggle 14.
  • the pivot link 13 is pivotally mounted on the pivot 15. As shown in Figure 5, retraction of the solenoid rod 11 away from the pivot 15 causes the toggle 14 to move towards the faceplate 8. This in turn moves the bolt 6 out from the faceplate 8.

  • the preferred embodiment includes a single control module 3 for all of the functions of the lock. These functions include: sensing whether the door is closed, controlling the solenoid, sensing the level (for potential difference) of the supply voltage, providing a drive signal for the solenoid 4, and adjusting the characteristics (such as the pulse width) of the drive signal.
  • the control module 3 When the lock is to be activated, the control module 3 provides an initial drive signal pulse to the solenoid 4 to initially move the solenoid rod 11. This pulse may be at whatever voltage is supplied, providing that it is sufficient to move the solenoid rod 11. After the initial pulse and a given delay (such as 200 milliseconds), the control module supplies a holding drive signal to the solenoid 4.
  • This holding drive signal is optimised for the particular lock. It is intended to be just sufficient to hold the solenoid rod 11 against the force of the spring 10. It is also intended to minimise power consumption of the lock. Factors to be considered in such an optimisation will depend on the characteristics of the particular lock and will be apparent to those skilled in the art. However, examples of such characteristics are: the inductance of the solenoid, the heat dissipation characteristics of the solenoid, and the spring constant of the spring 10.
  • the preferred embodiment supplies a holding drive signal which is pulsed and the width, or on-time, of the pulses is modulated.
  • the inductive properties of the solenoid are used such that a suitable current is passed through the solenoid by the application low pulsed signal.

  • the pulse widths will vary with the level of the supply voltage.
  • the control module 3 is also programmed so that the changing of a single switch 25 changes the electrical operation from power-to-lock to power-to-unlock.
  • the technician also follows the mechanical procedure for changing the configuration or mode of the lock.
  • the suitable current may be experimentally or empirically determined before manufacture. This may establish a predetermined current (or set of currents) which are suitable to hold the solenoid rod 11 against the spring 10. These currents or parameters representative on them may then be stored in the controller module 3, in a memory associated with a microcontroller included in the control module 3. This control module 3 may then be programmed to calculate a pulse width modulation for the drive signal of the solenoid 4, where a holding action is required, that will satisfy the current criteria. This calculation requires the sampling, or measuring, of the supply voltage. The value obtained is, of course included, in the calculation. Any other parameters, such as the inductance of the solenoid, may be included in the calculation as determined by those skilled in the art.
  • the electric lock 1 may be supplied with voltages anywhere between 8 and 40 volts DC. Electric lock 1 automatically compensates for any changes in the voltage and adapts to the new voltage without any need for an operator to make any adjustments.

  • the activation link module 5 may include a reed switch (not shown) which indicates its alignment with a reed magnet 31 on the strikeplate.
  • a reed switch (not shown) which indicates its alignment with a reed magnet 31 on the strikeplate. This arrangement allows the control module 3 to determine whether the door is in a closed position. This, in turn, allows delays relating to the door closing or opening to be built into the function of the electric lock 1. It also allows the control module 3 to save power by coordinating its operation with the opening .and closing of the door. Typically, two delay facilities are incorporated. First, a delay of eight seconds, for example, may be applied after the electric lock 1 is signalled to unlock the door. This signal may be supplied by the push button 24, or the like being pressed.
  • this signal may be provided by alternative means, such as a computer controlling the doors throughout a particular building, by a swipe card module, a key or password module, or any other suitable means known to those skilled in the art.
  • This delay allows that the door may be opened before the expiring of the delay after the signal to unlock has been given. This may be necessary or convenient where the signalling means is placed some distance from the door.
  • the lock also provides signals external to the lock to indicate whether the door is open or closed by means of the reed switch, and whether the solenoid is hard on, by means of a micro switch, 40 included in the solenoid. These signals may be received by a user or a building control system.
  • the preferred embodiment of the electric lock 1 allows that this delay may be adjusted during manufacture of the electric lock 1.
  • Another delay may be applied after the door is closed and before the bolt is extended.
  • This delay may, typically, be two seconds after the reed switch 30 detects that the electric lock 1 is in line with the strikeplate 7 provided that the reed contact is maintained in steady state for two seconds.
  • This feature facilitates use of the preferred embodiment with double acting doors to prevent the bolt from being protruded before the door is correctly aligned and in a stable position. The preferred embodiment allows that this delay may be adjusted during manufacture.

Abstract

La présente invention concerne une serrure électrique. Le fonctionnement de la serrure peut être changé par l'utilisateur par réglage d'un composant de commutation (14) dans l'actionneur de verrou. Ce réglage s'opère conjointement avec le déclenchement du fonctionnement électrique de la serrure au moyen d'un simple commutateur cavalier (25). Cette conception, dans laquelle le mode de fonctionnement (c'est à dire, fermeture sous maintien ou ouverture sous maintien) peut être choisi par l'utilisateur, permet de commercialiser la serrure, fabriquée selon la présente invention, selon un modèle unique. La serrure est aussi équipée d'un système manuel de priorité (101), de préférence à clé, qui fonctionne de manière mécanique et/ou électrique. Cette réalisation se substitue au fonctionnement normal de la serrure. La serrure décrite selon la présente invention se présente en un seul bloc, compact, et demande peu de réglage pour son installation et son fonctionnement. Ladite serrure contient de plus une possibilité de détection automatique (20,21,22,23) de la tension d'alimentation qui lui est appliquée.
