Definitions

  • the invention relates to an electrically switchable locking device for a window or a door with a leaf, preferably a rotating leaf, which can be opened and closed, and an application of a piezoelectric actuator and / or a magnetostrictive actuator and / or a shape memory actuator.
  • a conventional door opener which has an electromagnet for actuating a pivotally mounted striking plate.
  • EP-OS 0 280 845 a conventional electric lock with an electric motor for actuating the bolt is known.
  • a similar electrical control actuator is known from DE-GM 94 03 769. It has a DC electric motor as an actuating device.
  • the invention has for its object to provide an electrically switchable locking device of the type mentioned, which is simpler. It should preferably be able to be carried out with a small size.
  • the invention achieves the object with the subject matter of claim 1. Furthermore, the invention provides, according to claim 42, new applications of a piezoelectric actuator and / or a magnetostrictive actuator and / or a shape memory actuator.
  • the locking device has a striking plate and a bolt which interacts with the striking plate, the striking plate and / or the bolt having the actuator.
  • the striking plate can - as with a conventional door opener - be designed as a movably mounted door opener latch.
  • a movable striking plate is preferably mounted in the frame.
  • the bolt cooperating with the striking plate can be mounted as a spring-loaded catch, in the manner of a so-called lock latch, preferably in the door leaf, or as a fixed bolt on the door leaf, preferably engaging behind the striking plate or engaging in the striking plate. It can also be provided that the bolt can be operated using a key. This results in designs which can be used in the manner of a conventional door opener and can preferably be mounted on the door in the same arrangement as this.
  • Preferred versions of the locking device can also be used in an electrical door lock, which is designed and assembled essentially like a conventional electrical lock for escape and rescue route doors.
  • the invention provides a piezoelectric actuator or a magnetostrictive actuator or a shape memory actuator for actuating the lock. This results in smaller sizes, so that this lock also elsewhere in the door, for. B. can also be installed internally.
  • the energy required for the electrical application can be provided by a battery which is preferably arranged in the locking housing.
  • the actuator is designed as a piezo bending transducer and blocks a movably mounted latching element when it is acted upon electrically.
  • This locking element is in operative connection with the actual latch of the door opener latch.
  • This operative connection is preferably carried out via pairs of cylindrical rollers interacting in the manner of a lever or via a lever linkage. This allows a particularly compact and low-friction design to be implemented.
  • the switching can take place depending on the room temperature.
  • an electrical heater can be provided, which can be switched on or off accordingly to actuate the actuator.
  • a piezoelectric actuator 17 is mounted in a holder 12 which is fixed to the wall 2 in a stationary manner. When a voltage is applied, the actuator 17 expands. The force thereby acting on a lever arm 16c of a lever 16 mounted in a fulcrum 16a is converted in such a way that a profile iron 15 located on the door 1 is clamped by the second lever arm 16b. If the voltage fails or is interrupted, door 1 is released immediately. In order to separate lever 16 and door 1 in this released position, a return spring 14 is attached to lever 16.
  • the construction described here can also be realized with a magnetostrictive actuator (Tefenol D-rod).
  • the spring 27 carries at its free-standing end 27a a locking bolt 28 which engages in a groove 29 in the door frame 2 for locking.
  • a force F acts.
  • k 0.2
  • the spring 27 must be designed for 20% of the force F.
  • tension and compression shape memory springs 27 are available, one is the realization open in case of danger "and on the other hand the realization close in case of danger ".
  • the use of the shape memory springs 27 is only useful in temperature-critical areas, since otherwise an electrical heating source is required to set the springs 27.
  • a conventional electric door opener is based on the electromagnetic principle. By closing the excitation circuit, a coil generates a magnetic field. This magnetic field releases a locking mechanism so that the door can be opened.
  • FIG. 3 an alternative solution based on the piezoelectric principle is shown in principle.
  • the rotating body 35 (door lock unit) is rotatably mounted about an axis 33.
  • the torsion spring 34 ensures that the rotary body 35, after having moved from the starting position to the left about the axis of rotation 33 by opening the door, returns to the starting position.
  • a movement of the rotating body 35 is, however, only possible if the guided blocking pin 36 (guide not shown in FIG. 3) releases the rotating body 35.
  • the blocking pin 36 engages in the recess 35a in the rotating body 35 and prevents its rotating movement.
  • the rotary movement is released by applying a voltage U to the piezo bending transducer 37.
  • the voltage U in the piezo bending transducer 37 causes a change in shape such that the blocking pin 36 moves upward.
  • FIG. 4 shows an exemplary embodiment according to the invention of a door opener with a piezo bending transducer 7.
  • a section of the frame 2 with the locking device 3 mounted therein is shown. This interacts with the bolt 51 of the lock latch 5 located in the door leaf 1.
  • the latch 51 is designed as a spring catch.
  • the locking device 3 consists of a housing 31 of cuboid shape, in which the piezo-bending transducer 7 and a plurality of transmission elements interacting in a lever-like manner are accommodated.
  • the transmission elements are the retaining latch 61, which is designed as a rocker arm and is rotatably mounted about an axis 61a.
  • the holding bolt 61 is designed as a two-armed lever with the lever arms 61b and 61c.
  • the lever arm 61b acts together with two displaceably mounted pairs of cylindrical rollers 62, 63, which are each acted upon by a spring 64, 65 and are each positively guided in a cage (not shown). Apart from the executives in the cage, only rolling friction occurs, which means that the device can be designed with very little friction.
  • the two rollers of the roller pairs 62, 63 are each arranged next to one another transversely to their direction of displacement.
  • the spring 64, 65 assigned to the respective pair of rollers 62, 63 acts along the direction of displacement.
  • the first pair of rollers 62 with the rollers 62a and 62b is displaceably mounted in the housing 31 in a direction perpendicular to the direction of movement of the lever arm 61b, that is to say in the longitudinal direction of the housing, and the second pair 63 with the rollers 63a and 63b in a direction perpendicular to the first pair 62, in the transverse direction of the housing.
  • the second pair of rollers 63 is also firmly connected via the cage (not shown) to a likewise movable latching element 66, which together with the piezo bending transducer 7 forms the actual locking mechanism.
  • FIG. 5 shows an enlarged illustration of the piezo bending transducer 7.
  • the illustration shows the idle state, ie without electrical loading in the unlocked state.
  • This rod-shaped piezo bending transducer 7 is firmly connected to the housing 31 at one end 7a (can be seen in FIG. 7) and carries a metal nose 71 with a bevelled edge 71a near its freely protruding other end 7b.
  • the latching element 66 with a groove 66a is arranged opposite this metal nose 71.
  • the position and design of the groove 66a is designed in such a way that the piezo-bending transducer 7 engages with the groove 66a during a bending movement in the direction of the latching element 66 and thereby blocks movement of the latching element 66 and the connected pair of rollers 63.
  • the metal nose 71 and the groove 66a form one in relation to the pivoting direction of the voltage-actuated piezo bending transducer 7 inclined plane ", the wedge angle is selected so that self-locking or jamming of the mechanism when releasing the block is avoided in any case.
  • the nose 71 engages in the groove 66a of the latching element 66 and the door 1 is locked.
  • the pairs of cylindrical rollers 62, 63 are then in the position shown by solid lines in FIG.
  • the holding bolt 61 is also held in the position shown, engaging behind the bolt 51 of the lock latch 5 and preventing the door 1 from opening.
  • the first pair of cylindrical rollers 62 prevents the holding bolt 61 from pivoting back into the open position 61 ′ (shown in broken lines).
  • This pair 62 is axially movable in the housing 31 and is urged by the spring 64 (FIG. 4) into the path of movement of the holding bolt 61.
  • This first pair of cylindrical rollers 62 is itself prevented from evasive movement by the second pair of cylindrical rollers 63 in the locking state shown.
  • This second pair 63 is acted upon by the spring 65 (FIG. 4) and is mounted in the housing 31 such that it can move in the transverse direction of the housing.
  • the second pair of cylindrical rollers 63 is firmly connected to the locking element 66, not shown in FIG. 6, so that when the locking element 66 is blocked, the pair of cylindrical rollers 63 is also blocked.
  • the locked state Fig.
  • the design must be very low-friction. This is ensured by the use of the cylinder rollers 62a, 62b, 63a, 63b, preferably steel rollers, rolling on one another. As a further advantage of using rollers 62a, 62b, 63a, 63b, the device can be made very compact. In alternative embodiments, individual rollers or pairs of more than two rollers can also be used instead of the roller pairs 62, 63.
  • Figure 7 shows a representation of the embodiment in Figure 4 in plan view.
  • a printed circuit board 8 which has the electronic control (not shown) for the piezo bending transducer 7, is also accommodated in the housing. If the energy is supplied by a battery, this can also be arranged in the area of the printed circuit board 8.
  • a switch contact 82 is provided as a sensor for the locked state of the door 1 and as a feedback unit. The switching contact 82 is triggered via a contact pin 81.
