Definitions
- the invention relates to an electrically actuated door opener for releasing a door with a pivotable pivot latch, which is designed for holding or releasing a latch, with a locking lever, with a change between a position blocking the pivotal latch and the pivotal latch releasing position is movable, and which is arranged in relation to the locking lever, that it is lockable in the blocking position by the locking lever, with a positioner, via which the locking lever is movable from the change-locking position to a position releasing the change.
- the invention further relates to a method for unlocking a door opener.
- Electrically actuated door openers are known. They usually have a pivoting latch into which a snap trap engages in the locked state and is held there. In the releasing state, the pivotal latch is pivotable against a spring force and can thus release the latching latch.
- the release of the pivot latch is generally electrical and is triggered by a person via buttons or automatically by an access control system.
- linear positioners which have an armature which is electromagnetically moved in the linear direction.
- the armature is free to move at rest and can be moved by externally applied shocks or vibrations. This can lead to the door opener releasing the pivoting latch by manipulation from the outside.
- the electric door opener In order to reliably prevent unauthorized access, it is therefore necessary for the electric door opener to be as insensitive as possible to external impact.
- the pivotal latch is biased, for example, as a person already presses against the door. If an attempt is made to remove the pivot latch of the door It can lead to a blocking, which prevents a release of the pivotal latch. Therefore, it is desirable that the door opener can be released even with a preload on the pivot latch.
- the opening mechanism should be particularly space-saving and, for example, be integrated into a standard door opener housing.
- the advantages of the invention are in the low power consumption of the DC motor used, in the open ability of the door opener even under relatively high preloads, in the low noise during the opening process, which is still audible to the extent that an operator of this noise an indication the opening readiness of the door opener can be seen, and in the comparatively space-saving feasibility of the door opener.
- the positioner is arranged sperrhebel document and formed for the transmission of vibration movements on the locking lever.
- the position indicator in the sense of the invention is that which triggers a movement of the locking lever from the position locking the change into the position releasing the change.
- the positioner includes, for example, an electric motor.
- the positioner according to the invention is thus not fixed or static on the housing of the door opener, but on the side of the locking lever.
- the positioner is preferably indirectly connected via transmission elements and in particular directly to the locking lever. This results in that the positioner essentially moves with the locking lever.
- the opening operation of the door opener is thus not triggered by, for example, shock excitations, but by a structural unit oscillating in its entirety comprising at least the locking lever and the position indicator.
- a significant advantage of this particular arrangement is compared to the door openers described in the prior art thus, inter alia, in a particularly effective reduction of energy losses due to frictional forces, since the positioner is used in its entirety with the vibration transmission.
- the positioner has a shaft and a shaft drive, wherein further for generating the vibrational motion wave output side radially to the rotational movement of an asymmetric mass distribution is present.
- This particular embodiment is characterized by its relatively simple structure and its associated high reliability of function for generating vibrations.
- the shaft drive sets the shaft in a rotational movement about the shaft axis. Due to the fact that, in the case of this embodiment, a mass distribution which is asymmetrical radially to this rotational movement is provided on the output shaft side, an imbalance, which triggers the oscillation movement or vibrations, is produced when the shaft rotates.
- the shaft drive is preferably carried out by an electric drive.
- the use of a DC motor has proved to be particularly reliable and therefore preferred.
- An outstanding advantage of the DC motor over other types of motor is, inter alia, the low power consumption and the comparatively space-saving feasibility.
- the arrangement of the shaft is advantageously carried out in such a way that the triggered by the positioner vibrations or vibrations also trigger a release of the change suitable movement of the locking lever.
- This is particularly effective when the axis of rotation of the shaft is parallel to the pivot axis of the locking lever.
- the vibrations triggered by the positioner then run in the pivoting plane of the locking lever, whereby a particularly effective utilization of the vibration energy generated by the positioner is possible.
- This efficient utilization of the vibration energy thus allows, for example, the use of comparatively "small" or low-power vibration exciters or shaft drives, so that inter alia, the energy requirements of the door opener can be lowered or the space requirement of the shaft drive the cramped spatial conditions in a door opener is particularly well ,
- the door opener further comprises a swingable bearing device, via which the position indicator is mounted deflectable together with the locking lever.
- a bearing device is preferably a bending plate, which is connected for example on one side via a connection point fixed to the door opener housing.
- the bending plate is further formed such that it has a remote from the joint area on which the locking lever and / or the position encoder is arranged.
- the oscillatory bearing device or the bending plate can be directly connected to the position transmitter and or with the locking lever.
- connecting elements in particular connecting jaws and / or rubber and plastic elements, to be present for connecting the blocking lever and / or the position indicator to the bearing device.
- the bending plate is flexible, so that the entirety of locking lever and position sensor with respect to the door opener housing is movable or deflected.
- the extent of the possible deflection is expediently chosen so that the locking lever can be moved at least from the position blocking the change in the position releasing the change.
- the oscillations triggered by the positioner are based on the essentially Chen firmly connected to the positioner locking lever are transmitted and the positioner and the locking lever is arranged indirectly via the bending plate in the door opener or connected thereto.
- a major advantage of this arrangement with storage device is in a particularly with respect to the functional integrity particularly secure attachment of the position indicator and the locking lever in the door opener.
- the shaft is further arranged in the door opener, that the axis of rotation of the shaft is perpendicular to the pivot axis of the change.
- This arrangement is particularly space-saving and thus advantageous in view of the limited space available.
- the shaft in this embodiment is preferably arranged lying or standing.
- An encoder which is designed to generate sinusoidal oscillatory movements, has proved to be particularly suitable because sinusoidal oscillatory movements trigger a vibration of the locking lever particularly efficient.
- Outstanding Entriegelungseigenschaften has an inventive door opener whose positioner is designed to generate vibrations whose amplitudes is less than the release path between the locking lever and the change.
- the release path refers to the distance that the interlocking locking lever must be moved until the locking lever is in a position releasing the change.
- This embodiment is equally advantageous in several respects. On the one hand, it is ensured in this way, for example, that the vibration generated by the positioner transmitted to the locking lever is not so great that the locking lever strikes against the vibration movement of the locking lever limiting components of the door opener at each performed vibration movement.
- This door opener is therefore particularly wear-resistant.
- a particularly efficient transmission of vibration generated by the positioner succeeds when the positioner for excitation of the locking lever and in particular of the oscillatory bearing means, especially the bending beam, is formed in natural frequency.
- the object is also achieved with a method for unlocking a door opener described above comprising the steps a) lever side generating vibrations, b) transmitting the vibrations on the locking lever and c) vibration-controlled displacement of the locking lever in a change releasing position.
- a method for unlocking a door opener described above comprising the steps a) lever side generating vibrations, b) transmitting the vibrations on the locking lever and c) vibration-controlled displacement of the locking lever in a change releasing position.
- the unlocking process according to the invention thus generates vibrations thus lever side and not door opener housing side.
- the transmission of the triggered by the encoder oscillations on the locking lever thus succeeds particularly effective and allows reliable displacement of the locking lever in a position in which the door opener is ultimately unlocked.

- Fig. 5 side view of the door opener of Fig. 4;
- Fig. 6 Perspective oblique view of the door opener of Fig. 4 on the range of the position indicator.
- an electrically actuated door opener 1 according to a first embodiment of the invention is shown.
- the door opener 1 is usually permanently installed in a door frame. It has a housing 2, on which a cover plate (not shown) is applied by means of screws in order to close the interior of the door opener 1.
- the door opener 1 comprises a pivot latch 3, which is held against a spring force about a pivot axis pivotally mounted in the housing 2 and can be pivoted in the direction of the housing interior.
- the pivotal latch 3 is shown in Fig. 1 in an initial position and serves to a snap trap (not shown) which o.a. is arranged to hold or release.
- the pivoting catch 3 is provided with a projection 4, behind which the latching latch can latch.
- a terminal block 5 is provided, can be created via the electrical connections to a positioner located in the door opener.
- a change 6 is pivotally mounted on a removable shaft 7 and pivotable about this axis.
- the pivot axis of the change 6 runs orthogonally to the pivot axis of the pivot latch 3.
- the change 6 is shown in a blocking the pivotal latch 3 position and strikes with a blocking region 8 against the pivoting latch 3. The pivotal latch 3 is thus blocked and can not swing into the door opener housing 2 due to the blockade of the change 6.
- a locking lever 9 is also provided, which is pivotable about a locking lever axis 10.
- the locking lever axis 10 extends parallel to the change axis 7.
- the locking lever 9 prevents in the blocking position shown in Fig. 1, the change 6 to a pivoting movement.
- the locking lever 9 has a locking stage 11, which is in engagement with a control panel 12 located at the change 6.
- the door opener 1 is shown in a released position in which the pivot latch 3 (not shown) is released to release a snap trap.
- the change 6 and the locking lever 9 are in a released position. Accordingly, in FIG. 2, the locking lever 9, starting from FIG. 1, has been pivoted away from the change 6 in the direction of the arrow A in FIG. 1 and the change 6 has been pivoted away from the pivoting catch 3 in the direction of the arrow B in FIG.
- the change 6 can be pivoted from the blocking position into the pivotal latch 3 releasing position, the locking lever 9 must thus be moved so that the control slope 12 of the change 6 is no longer engaged with the locking stage 11 of the locking lever 9 , so that the change 3 with respect to the locking lever 9 is free to pivot.
- the pivoting of the locking lever 9 takes place against a force caused by the spring element 14, ie opposite arrow A of FIG. 1.
- the pivoting of the change 6, however, takes place against a spring force, which is effected by a coupled with the change spring element 13.
- the spring element 13 exerts a spring force on the change 7 in the direction of the blocking position, ie opposite arrow B in FIG.
- the movement of the locking lever 9 of the change 6 blocking position in the change 6 releasing position against the force exerted by the spring element 14 is effected by a position encoder 15 which is fixedly connected via a tab 16 directly to the locking lever 9.
- the rigid coupling of the position indicator 15 to the locking lever 9 is an essential basic idea of the invention.
- the position indicator 15 has a shaft 18, on the output side, an eccentric mounted mass 19 is attached.
- a DC motor 17 is present.
- a rotational movement of the shaft 18 can be due to the eccentric mass 19, the position sensor 15 and thus also the fixedly connected to the position encoder 15 locking lever 9 vibrate or vibrate.
- the positioner 15 If the positioner 15 is activated or in particular begins to rotate the shaft 18 driven by the DC motor 17, which also causes the eccentrically mounted mass 19 to rotate, the positioner starts to oscillate due to the rotation of the eccentrically mounted mass 19; to vibrate, wherein the vibration or vibration plane is substantially orthogonal to the axis of rotation. Due to the direct and firm connection of the locking lever 9 with the position encoder 15 and the locking lever 9 is caused by the rotating eccentric mass 19 of the position sensor 15 in vibration or vibration. The oscillatory movement or the vibration of the locking lever 9 is essentially determined by the locking lever axis, so that the locking lever 9 mostly in the direction of the double arrow D in Fig. 1 oscillates.
- the angle must be chosen so that the locking stage 11 does not slide by a mere counter-pressure against the locked door along the control slope.
- the control ramp 12 must run so pronounced that the oscillating locking stage 11, the control slope 12 can slide along and not with each swinging movement for change 6 back swing back to its previous position, bringing a movement of the locking lever 9 in the change 6 releasing position otherwise it would not be possible.
- FIG. 4 an electrically actuated door opener 1 'according to a second embodiment of the invention with a housing 2' is shown.
- the essential difference from the first embodiment of the door opener 1 consists in the oscillatory mounting of the structural unit of locking lever 9 'and the position indicator 15 via a bending plate 20th
- the bending plate 20 has for this purpose an elongated bar-shaped body, in its end region it is firmly connected to the door opener housing 2 '. This can be done for example by a solder joint, screwing etc.
- the bending plate 20 has a receptacle 22 for the position indicator 15 which is formed integrally with the bending plate 20.
- the position indicator 15 is thus connected via the bending plate 20 fixed to the locking lever 9 '.
- the receiving jaws 23/23 ' have rubber elements.
- Activation of the position indicator 15 causes the bending plate 20 in the direction of the double arrow E in Fig. 5 swing (indicated schematically by the dashed lines outline of the bending plate). Characterized in that the position indicator 15 is connected via the bending plate 20 fixed to the locking lever 9 ', the vibrations of the actuator 15 are transmitted to the locking lever 9' so that it oscillates in the direction of the double arrow F of FIG. 4.
- the further course of an opening Gangs with the above with respect to the first embodiment of the door opener 1 performed operations analog.
