  • the change to a pin which engages in the locked position in a recess mounted on the door opener housing. This prevents unintentional pivoting of the locking lever due to vibration or impact.
  • This door opener has an armature, which is designed as a two-armed lever, wherein the two lever arms in a line to each other are arranged and are rotatably mounted in their center of mass. Due to the mounting of the armature in the center of gravity unintentional pivoting of the armature in case of shock or shock is prevented.
  • door openers Without effective manipulation protection, there is a risk that a door opener may unintentionally open due to shaking or hard impacts or shocks, thereby allowing unauthorized access to a secured building.
  • door openers are used with impact protection to ensure a high safety standard even with appropriate manipulation attempts.
  • Object of the present invention is to provide a shock-proof door opener, which is structurally simple and has a high security against manipulation.
  • the door opener according to the invention has a locking device which cooperates via an interposed change with a movable door opener latch in order to switch it into a blocking position or a release position.
  • the locking device comprises a spool and a linearly movable over the spool ram, which cooperates with an element, preferably a locking lever of the locking device to actuate this between a locking position and a release position.
  • the plunger has a limit stop, which rests in the locked position on the coil or a bobbin and limits the path of the plunger.
  • the limit stop is formed from an elastomer, or a Elastomer element is arranged between the limit stop and the coil or a bobbin and / or the coil is connected to the housing via an elastomeric bearing.
  • elastomeric element is meant a damping component, which consists for example of a rubber or a rubber.
  • a rubber for example, a preferably vulcanized natural rubber or a vulcanized silicone rubber or an industrially manufactured rubber, for example, a butyl rubber (IIR) or polyurethane rubber (AU, EU) can be used.
  • IIR butyl rubber

  • the limit stop limits in particular the immersion depth of the plunger in the coil or in the bobbin.
  • the limit stop itself is formed of an elastomer or that the limit stop comprises an elastomer.
  • the elastomer dampens vibration impulses transmitted from the bobbin or coil to the plunger. This prevents that these vibration pulses can assume a value that automatically sets the plunger in the direction of the release position in motion.
  • an elastomer element between the limiting stop on the one hand and the coil or the bobbin on the other hand is arranged.
  • it is a separate elastomeric element which acts as a damping element to suppress vibration impulses transmitted from the coil and / or bobbin to the plunger.
  • the coil is connected to the housing via an elastomeric bearing.
  • the elastomeric bearing may in one embodiment, for example, have a sleeve which is surrounded by an elastomer, which in turn is in communication with the door opener housing.
  • the coil or a fixing pin of the coil is inserted into the sleeve and held there, for example screwed. This prevents direct metal-to-metal contact between the coil and the housing.
  • About the interposed elastomer is a effective vibration damping to suppress spikes transmitted from the housing of the door opener to the spool. This also achieves an effective damping of movement pulses and thus prevents the plunger from unintentionally moving from the blocking position in the direction of the release position.

  • the locking device has a coil-actuated safety stop which cooperates with an element of the locking device, preferably a locking lever or the change, to prevent release of the change.
  • the safety stop is actuated by the same coil which actuates the plunger.
  • the locking device comprises a rotatably mounted locking lever, which cooperates with the change.
  • the coil cooperates with the pawl by the plunger to actuate it between a locking position in which the locking lever is in abutment with the change, and a release position in which the locking lever is out of attack of the change.
  • the locking lever has two mutually angled lever arms, wherein the first lever arm interacts with the change and the second lever arm protrudes in the direction of the plunger and cooperates in the locked position with an actuatable by the coil safety stop to a release of the change and thus a Release the trap to prevent.
  • the Safety stop prevents the locking lever from rotating in the direction of the release position in the event of vibrations or shocks.
  • the locking lever In the case of shocks, shakes or blows in conventional door openers there is a risk that the locking lever will rotate automatically or due to its inertia in the direction of the release position.

  • the safety stop therefore complements the elastomeric element in order to obtain an effective and reliable impact protection of the door opener over a larger vibration range or vibration range.
  • the door opener can be designed in particular as a working current door opener, ie in the de-energized state the door latch is locked. That is, without energizing the coil, the locking lever is in the locked position.
  • the door opener is unlocked by energizing the coil and actuating the linearly movable plunger to switch the locking lever from the blocking position to the release position.
  • the plunger is moved by the coil in the direction of the first lever arm of the locking lever, comes into contact with this and takes with it.
  • the locking lever rotates so far that it comes out of engagement with the change, ie in the release position.
  • the coil also actuates the safety stop with the plunger so that it is ensured that the locking lever can be switched to the release position.
  • Safety stop is designed as a movable safety stop. It is moved out of the range of movement of the locking lever when unlocking the spool. By the same coil actuates both the safety stop and the linearly movable plunger, it is prevented that it can malfunction by the locking lever can not be switched by the coil in the release position, because the backup stop is still effective by mistake.
  • the locking lever cooperates with a spring and is acted upon by the spring in the blocking position.
  • the safety stop is provided as an additional safeguard, should the force of the spring no longer be sufficient to hold the locking lever in the locked position as a result of shocks.

  • the locking lever is then rotated by a spring in its locked position, thus blocking the change or the door latch.
  • the securing stop protrudes in the blocking position into the range of movement of the locking lever, in particular of the second lever arm and thereby prevents pivoting of the locking lever.
  • the locking lever is rotatably mounted. When switching the locking lever in the release position of this covers a certain range, the range of movement of the locking lever.

  • the coil acts on the safety stop to to move it out of the range of movement of the second lever arm during the switching of the locking lever from the locking position to the release position.
  • Protruding into the range of motion means that in particular there is no adhesion between the safety stop and the locking lever.
  • the safety stop loosely abuts against the second lever arm of the locking lever.
  • Loose abutment means that there is loose contact between the safety stop and the second lever arm, or that the safety stop is spaced from the second lever arm so that there is a gap or some play between the safety stop and the second lever arm. In this way, jamming of the door opener is reliably prevented. Even with high preload is thus ensured that the locking device without problems between the release position and the locking position can be switched.
  • the second lever arm protrudes freely in the direction of the plunger. That is, the second lever arm extends from the first lever arm in the direction of the plunger, without being applied to the plunger.

  • the safety lever is retracted by the magnetic force of the coil, i. pulled out of the range of motion of the locking lever, so that the locking lever can swing freely.
  • the plunger When energizing the coil, the plunger is simultaneously moved in the direction of the first lever arm of the locking lever comes with this in abutment and then pivots the locking lever about its axis of rotation to unlock the change or the case.
  • the distance traveled by the plunger to switch the locking lever from the locking position to the release position is longer than the distance to be traveled by the locking pin to release the locking lever. This ensures that temporally first the backup stop releases the range of motion of the locking lever and then the locking lever can be pivoted by the plunger.
  • the safety stop is arranged on the plunger.
  • the securing stop may be formed as a securing ring, which is mechanically connected to the plunger and has a larger diameter than the plunger.

  • the locking ring 251 is also designed as a limit stop 23b, which rests in the locking position on the bobbin 22k.
  • the bobbin has an elastomeric member 27 provided between the limit stopper 23b and the bobbin, and as a damping member for suppressing vibration peaks due to tampering attempts or impact tests serves.
  • a blocking device 3 which holds the plunger 23 in its locking position.
  • the blocking device 3 has a blocking element 31t, which is rotatably mounted on the second lever arm 242 of the locking lever 24.
  • the pivot bearing of the blocking element 31t has an axis of rotation 31 a, which runs parallel to the axis of rotation 24a of the locking lever 24.
  • the blocking element 31t is normally in the in Fig. 4a Lock position shown held out of engagement with the plunger 23.
  • the blocking element 31t rotates into the range of movement of the plunger 23 due to its inertia. If the plunger 23 now moves in the direction of the first lever arm 241 due to impacts or vibrations, it comes into contact with the blocking element 31 t, which effectively prevents further movement of the plunger 23. At the same time, the second lever arm 242 with its stop surface 243 in abutment with the locking ring 252 and prevents the locking lever 24 can be rotated in the direction of the release position.
  • the door opener 1 has an impact protection device with two securing devices, namely the securing device 2 and the blocking device 3.
  • FIGS. 5a and 5b another embodiment of the door opener 1 is shown.
  • the safety device 2 comprises, as in the embodiment described above FIGS. 4a and 4b , arranged in the region of the tip of the plunger 23 circlip 252, which serves to secure the locking lever 24 in its locking position with a in the region of the free End of the second lever arm 242 arranged abutment surface 243 cooperates.
  • the securing ring also serves as a limit stop 23b, which rests in the locking position on the bobbin 22k.
  • the limit stop 23b has an elastomer element 27.
  • the elastomer element 27 is arranged on the bobbin 22k facing side of the limit stop 23b and connected thereto.
  • the elastomer element damps vibrations and prevents impulse peaks from being transmitted from the bobbin 22k to the plunger 23 during vibrations.
  • the stop surface 243 also comes into contact with the securing ring 252 and effectively prevents the blocking lever 24 from pivoting in the direction of the release position.
  • the door opener 1 comprises a blocking device 3 with a blocking element 42m, which is arranged on the collar 231 of the tappet body 232.
  • the blocking element is mounted on the peripheral surface of the collar 231 in a recess.
  • the blocking element 32m is acted upon by a spring in the direction of the change 13 and engages in the locking position in a recess 131 of the change 13 a.
  • the plunger 23 is blocked in the locked position by the change 13.
  • About the blocking element 32m so the plunger 23 in his in the Fig. 5a Lock position shown held and secured against unintentional extension in the direction release position.
  • the coil 22 is energized.
  • the blocking element 32m is attracted and pivots into the collar 231 of the plunger body 232. That's what happens Blocking element 32m out of engagement with the change 23 or the recess 131 of the change.
  • the blocking element 32m is magnetically actuated.
  • the blocking element 32m may be formed of a ferromagnetic material or have a permanent magnet.
  • the plunger 23 can move in energized coil 22 in the axial direction of the locking lever 24. At the same time, the plunger 23 takes along the securing stop 25 and moves it out of the range of movement of the blocking lever 24. This has the consequence that the locking lever 24 about the rotation axis 24a in the in Fig. 5b can rotate shown release position. The rotation of the locking lever 24 is finally carried out by the plunger 23 and the plunger tip 233 comes into contact with the first lever arm 241 and thereby moves the first lever arm 241 in a clockwise direction. Characterized the locking lever 24 is pivoted about the axis of rotation 24a and formed by the roller 244 and the support of the change 13 stop is released.
  • FIGS. 5a and 5b another embodiment of the door opener 1 is shown.
  • the blocking element 33m is not arranged on the collar 231 of the plunger body 232.
  • the blocking device 3 instead has a blocking element 33m which is rotatably mounted directly on the plunger body 232 in a recess. Via a spring 34a, the blocking element 33m out of the plunger body 232, ie in the in the Fig. 6a shown locked position.
  • the blocking element 33m engages behind an edge 22a arranged on the coil 22 or in the bobbin 22k.
  • the blocking element 33m is actuated magnetically. This can do that Blocking element 33m be formed of a ferromagnetic material or have a permanent magnet.
  • the coil 22 is energized. About the built-up of the coil 22 magnetic field, the blocking element 33m is pivoted into the plunger body 232 and comes out of engagement with the locking edge 22a. Now, the plunger 23 can extend due to the magnetic force of the coil 22 in the direction of the locking lever 24 and pivot about the axis of rotation 24 a.
  • the energization of the coil 22 is turned off. After switching off the flow of the plunger 23 is returned by the return spring 26 in the in the Fig. 6a moved shown locking position. At the same time the locking lever 24 and / or the change 13 is urged by spring force in the locked position to block the case 12.
  • the blocking element 33m is pushed out of the plunger body 23 due to the spring force and comes again into engagement with the blocking edge 22a.
  • the plunger 23 is fixed again.
  • the securing device 2 which comprises a arranged in the region of the plunger tip 233 circlip 52 which is arranged in the movement range of the second lever arm 242, the locking lever 24 is secured in the locked position.
  • stop surface 243 comes into contact with the stop surface 253 of the locking ring 252. This prevents pivoting of the locking lever 24 toward the release position and the door latch 12 remains securely locked even in tampering attempts.
