Definitions

  • the invention relates to a door lock according to the preamble of claim 1.
  • an electronic door lock for an electronic key provided with an electrical memory for keyword information is known, with a lock housing, which can be actuated at least from the inside of the door by means of a handle, in a striking plate engaging trap, a bolt which can be locked into the striking plate, an electrically controllable locking mechanism for the bolt, a reading device for the keyword information of the electronic key and a control circuit which controls the locking mechanism as a function of the read keyword information.
  • the additional patent application is based on the problem of simplifying the locking mechanism of such an electronic or electric door lock, in such a way that its electric drive motor is relieved of forces exerted externally on the bolt.
  • the locking mechanism has a spring driving the bolt in one of its directions of movement and an electric motor driving the bolt opposite to the spring drive direction via an electric drive which only positively engages in the opposite direction to the spring drive direction, with the bolt being assigned a locking bolt mechanically controllable via the transmission , which blocks the bolt at least in the bolt end position achievable in the motor drive direction.
  • the bar is therefore with the The previously described, not previously published additional patent application driven by the electric motor only in one direction, namely, moved into the lock housing.
  • the electric motor tensions the spring driving the bolt in the other direction, that is, in the direction of exclusion.
  • the gearbox which is preferably a cam gearbox, is designed in such a way that the output force of the motor can only transmit the driving forces in the drive direction assigned to the motor. If, on the other hand, a force is exerted on the bolt in the motor drive direction, the cams of the cam gear lift up from one another and relieve the load on the electric motor. If forces are exerted on the bolt in the opposite direction, the motor is protected by the blocking bolt.
  • the locking bolt locks the bolt in both directions, so that the bolt is fixed in both end positions and is protected both against insertion into the lock housing and against pulling out. The latter could e.g. B.
  • This locking bolt can be pivoted on the lock housing mounted locking pawl can be formed which is resiliently biased in locking engagement with the bolt and can be disengaged via a control cam drive depending on the drive position of the drive.
  • the locking pawl should preferably engage directly on the bolt.
  • the door lock should only have a door handle coupled to the latch on the inside of the door, ie the protected side of the door.
  • the latch is actuated from the outside of the door by the electric motor driving the bolt.
  • the bolt can be driven in the motor drive direction beyond the end position determined by the locking bolt, releasing the striking plate and, in the course of this movement section, retracts the latch via a pivoting lever which is mounted on the lock housing and is coupled to the latch. If the bolt is subsequently returned to the end position determined by the blocking bolt, the door lock is unlocked and can only be closed using the latch function.
  • the door lock In emergencies and in the event of a defect in the electrical components, the door lock must be able to be opened from the inside of the door, even if the bolt is locked in the striking plate. This can be achieved in that the pusher which can be actuated from the inside of the door is coupled to the latch via a first follower and to the bolt for the common retraction movement of the latch and the control via a second follower. This is called the "anti-panic function" of the electrical or electronic lock. From the inside of the door, both the latch and the bolt can be opened in a purely mechanical way using the lever handle. From the outside of the door, d. H. From the unsecured side of the door, the door lock is only opened by the electric motor, which drives (moves) the bolt and also the latch via a change lever.
  • the locking status of the bolt can be monitored. Monitoring can also be used in connection with alarm systems or central locking systems. With conventional door locking systems, the closed state the door is monitored by contacts attached to the door frame on the one hand and to the door leaf on the other hand, in particular also reed contacts. However, this type of monitoring is unsafe and depends on the construction tolerances of the door. It is therefore proposed in the additional patent application to attach magnetic field sensors to the part of the bolt and the latch which can be locked into the striking plate and which cooperate with a magnet arranged on the striking plate. This type of arrangement facilitates the supply of electrical lines to the magnetic field sensors and allows the proper closing functions of the electrical drive to be monitored.
  • the bolt's magnetic field sensor and the latch are not activated even if the latch or latch is properly excluded from the lock housing.
  • the position of the bolt relative to the lock housing is recorded by means of an additional magnetic field sensor-magnet arrangement. Either the retracted position or the excluded position, possibly both positions, can be monitored.
  • the closed state can be determined from the combination of the signals supplied by the magnetic field sensors and a signal representing the functionality of the door lock can be derived.
  • the magnetic field sensors are preferably Hall switches.
  • the invention has for its object to improve an electrical or electronic door lock, in particular mortise lock, of the type required according to the invention in that latch and latch can be moved into the lock housing by a motor.
  • the task should be solvable with such electrical or electronic door locks, especially mortise locks, which have the dimensions according to DIN 18 251.
  • the special design of the plug-in door lock according to the invention ensures that the latch and bolt can be moved into the lock housing by motor and the bolt can be moved out of the lock housing by motor.
  • the special structural design of the lock device ensures that the lock latch can also be easily moved into the lock case by a motor in the case of a relatively large transverse load, for example in the event of a frictional connection to a strike plate.
  • the design and arrangement of the lock mechanism makes it possible with the inventive insert door lock that the panic function is ensured with only one lock nut.
  • an insert door lock according to the invention is extremely compact, so that the invention can be implemented with insert door locks according to DIN 18 251.
  • the electric motor when the latch and bolt are moved in, the electric motor first drives the lock bolt with a different ratio than the latch when it is moved into the lock housing.
  • the translation is reversed or changed shortly before or immediately at the start of the motor-driven movement of the trap in such a way that relatively large forces are transmitted to the lock components provided for this purpose with the same motor, so that even if the trap is under tension or relatively large Non-positive connection on the striking plate of the motor drive in the lock housing is not overwhelmed ( claim 2 ).
  • the same lever on which the different lever arms for driving the bolt and latch are arranged can also serve at the same time to transmit the anti-panic function of the mortise lock according to the invention.
  • the nut is z. B. provided on the circumference with a cam which interacts with a curve which forms a materially integral part of the two levers. In this way you get a particularly compact design of the castle interior. There is therefore no need to provide two trigger nuts with two trigger mandrels ( claim 4 ).
  • the drawing illustrates a mortise lock, the dimensions of which were carried out in accordance with DIN 18 251.
  • a lock housing 1 of which a lock plate 2 can be seen in plan view in the drawing figures, a latch 3 and a bolt 4 are guided in the direction of their longitudinal center axis, that is to say axially displaceable, by a limited amount in each case.
  • the trap 3 is guided in an opening 5 of a cuff 6 of the lock housing 1, with a threaded bushing 7 fixed to the housing through an elongated hole 8 of a trap tail 9 passes through.
  • a latch spring 10 biases the latch 3 in the exclusion direction, such that the latch 3 has the tendency to move out of the opening 5 of the cuff 6 with its latch head 11.
  • the latch spring 10 is formed in the illustrated embodiment as a spiral spring and mounted with its winding eye 12 around a square mandrel 13 fixed to the housing, such that a spring leg 14 extends approximately parallel to the inside of the cuff 6 with a cranked length section resiliently against an inner wall 15 of the latch head 11 supports.
  • Another spring leg 16 serves as a closing spring and loads a pawl 17 in the direction of the bolt 4 with a bent length section. The function of the pawl 17 is described further below.
  • the reference numeral 18 designates a nut, the nut lever 20 of which acts with a spherically shaped part 21 against a projection 22 which runs normally (at right angles) from the latch tail 9.
  • the nut 18 is used on the secured inside of the door to receive a handle mandrel, not shown, which is arranged in the square opening 23.
  • a counter spring is designated, which biases the nut 18 via a web 66.
  • a further lever 24 is arranged, which carries at its free end on a one-piece shoulder mandrel 25 a roller 26 which abuts a cam track 27 of a lever 28 in a force-fitting manner.
  • the latch 3 against the restoring force of the latch spring 10 can thus be moved into the lock housing 1 via the pusher mandrel (not shown) and the nut 28.
  • the corresponding positions of the lock fitting parts in this position are shown in FIG. 1.
  • the power supply to the control circuit 30, the electric motor 29 and the reading device 31 takes place via a line 34 from a central power supply unit 35, which is provided with an accumulator for emergency operation.
  • the bolt 4 is guided in an opening 36 of the cuff 6 in its longitudinal axis direction.
  • the bolt tail has an elongated hole 37, into which a double mandrel 38 fixed to the housing engages.
  • the double mandrel 38 has a taper at a distance from the one housing wall, so that the bolt tail 39 is guided with a gap distance to the relevant lock plate 2 of the lock housing 1.
  • With 40 is also a double mandrel, which is also tapered at a distance from the lock housing wall.
  • the lever 28 is arranged to be pivotable by a limited angular dimension parallel to the lock plate 2 (lock housing base) shown in the drawing, with a gap distance to the lock housing 1.
  • This lever 28 engages over the bolt tail 39 and the pawl 17 and lies on the bolt tail 39.
  • the lever 28 has an elongated hole 43 through which a shoulder mandrel 44 which runs normal to the surface of the bolt tail 39 engages with a clearance fit.
  • the lever 28 On the side facing the bolt tail 39, the lever 28 carries two shoulder pins 45 and 46, which are formed in one piece with the lever 28, for example, recessed or riveted dowel pins.
  • the shoulder mandrels 45 and 46 are arranged at an angular distance from one another and lie on a circular arc. Both shoulder mandrels 45 and 46 touch the curved outer contour 47 of the pawl 17.
  • the lever 28 has two sector-shaped toothed rings 48 and 49 on its side facing away from the double mandrel 40.
  • the toothed sector 48 has the lever arm M with respect to the double mandrel 40 serving as a fixed axis, while the toothed sector 49 has the lever arm L with respect to the double mandrel 40.
  • the lever arm M is thus larger than the dimension A Lever arm L. Consequently, a driving force acting on the toothed sector 48 acts on a lever arm enlarged by the dimension M, so that an increased torque can be transmitted via the lever arm M with the same drive power when attacking the ring gear sector 48.
  • the bolt 4 is blocked by the pawl 17 against external forces and the electric motor 29 is protected.
  • the pawl 17 prevents the bolt 4 from being moved out, for. B. when slamming the door.
  • the pawl 17 is also arranged around an extension mandrel 50 to be pivotable by a limited amount at a distance from the lock housing base 2.
  • the attachment mandrel 50 fastened in the lock housing base 2 is tapered in diameter at a distance from the lock housing base 2.
  • the pawl 17 is pivotally mounted on this tapered length section.
  • the pawl 17 is constantly loaded by the spring leg 16 in the blocking pivot position, that is, biased in the direction of engagement.
  • the pawl 17 has a first and a second locking tooth 51 and 52.
  • the locking tooth 52 engages behind a shoulder 53 on the locking tail 39, while the locking tooth 51 behind a shoulder 54 of the locking tail 39 takes hold.
  • the first position corresponds to the position of the bolt in the lock housing, i.e. the position completely retracted into the lock housing (FIG. 3), and the second position corresponds to the position in which the bolt 4 is completely excluded from the lock housing 1 (FIG. 4).
  • the pawl 17 dips with a lever part 55 into a recess 56 of the bolt tail 39, wherein it carries out a pivoting movement around the shoulder mandrel 50. This is done in that the attachment pins 45 and 46 attached to the lever 28 act when pivoting the lever 28 against the outer contour 47 and thereby the pawl 17 against the restoring force of the spring leg 16 - in the plane of the drawing upwards - pivot. This in turn happens in that the electric motor 29 is driven accordingly.
  • An axis 57 protrudes from the motor housing and has a worm 58, which meshes with a worm wheel 59, which meshes with an worm wheel 59, which extends around an axis 60, which is fixedly arranged in the lock plate 2 and runs normal (at right angles) to it. and can be turned.
  • a spur gear 61 is coupled, which in the embodiment shown is designed eccentrically in accordance with dimension A, so that one after the other either the ring gear sector 48 or after a certain angle of rotation, the ring gear sector 49 meshes with the spur gear 61, which results in a corresponding pivoting movement of the lever 28.
  • the electric motor 29 or the spur gear 61 are not moved because they are always controlled so that they are in the rest position come from the engagement area of the gear ring sectors 48 and 49.
  • the electric motor 29 thus causes not only the latch 3 and bolt 4 to be moved into the lock housing 1, but also the movement of the bolt 4 out of the lock housing 1.
  • the shoulder pin 46 lifts the pawl 17, and that Bolt 4 is moved through the link connection 43, 44 into the lock housing 1.
  • the axis 57 of the electric motor 29 is mounted in a worm bearing 65.
  • This screw bearing 65 can consist of a normal (at right angles) to the lock plate 2 and non-positively attached flat iron both in the lock plate 2 and in the lock cover, not shown. As a result, the axis 57 of the electric motor 29 is relieved both radially and axially.
  • the position in which the locking tooth 52 in question locks the bolt 4 in the open position is passed both before and after passing through the latch retraction position.
  • the electric motor 29 is expediently stopped in the position following in the direction of rotation in order to briefly open the latch 3 by pressing the key 33 once and subsequently to keep the bolt 4 open.
  • the trap opening time can be increased by turning delay in the operating state.
  • the electrically or electronically driven and / or controlled or controlled door lock enables monitoring of the closed state of the door and a functional check of the lock. It is therefore particularly suitable for alarm systems, especially alarm systems with a block lock function and for locking systems with a central locking function.
  • Hall switches are installed which respond to magnets in the associated engagement openings of the striking plate, not shown. This is not illustrated in the drawing. The Hall switches deliver signals to monitoring circuits, not shown, when the latch 3 and the bolt 4 fully engage in the striking plate.
  • the Hall switches only provide information about the closed state of the door, but do not allow complete conclusions to be drawn about the functionality of the door lock.
  • a further magnet, not shown, is therefore attached to the bolt 4, the position of which is detected in a Hall switch arranged in the lock housing 1.
  • the Hall switch responds when the bolt 4 is completely excluded. From the signals of the Hall switch, information can be derived as to whether the bolt 4 is excluded when the door is open or closed.
  • a third Hall switch is provided in the lock housing 1, which responds to a magnet of the bolt 4 in the open position of the bolt 4. The Hall switch can take over the function of the Hall switch when its output signal is inverted, so that one of the two Hall switches may be omitted. Monitoring both locking positions of the bolt 4 increases security.
