Description

The invention relates to an electric door opener with the features of the preamble of main claim 1.

Door openers constructed in this way are known as closed-circuit door openers and as working-current door openers.

In the known closed-circuit door openers, the electrical actuator of the electrically controllable switching device is usually designed as an electromagnet, which interacts with an armature designed as a lever. When holding magnets are energized, the lever arm of the armature is pulled into contact with the coils of the holding magnet and the electrically switchable locking device is held in the locked position. Such closed-circuit door openers are, for example, from the DE 42 29239 B1 , DE 102 46 665 C5 , EP 2 514 889 B1 and EP 3 156 565 A1 known. The disadvantage of closed-circuit door openers constructed in this way is that although they provide a high preload release, the maximum holding force (breaking force) of the door opener is limited by the holding force of the holding magnet.

In known working current door openers of the above structure, the electrical actuator of the electrically switchable control device is, for example, as Electric lifting magnet is designed, which controls the armature via a plunger. When the solenoid is energized, the armature is acted upon by the plunger in the release direction. Such power door openers, for example, are out EP 3 199 728 B1 and EP 3 199 230 A1 known.

Power door openers of this design have a high level of force, but with only purely mechanical blocking. The coil is only used for unlocking by energizing.

The object of the present invention is to create a door opener of the design mentioned at the beginning, which has good preload properties and also high resistance to being broken into.

Alternative No. 8: the pair of components X and Y is formed by the door strike as component X and the gear unit as component Y.

The number of eight alternatives is not exhaustive as it depends on the division of the components into subcomponents and/or common, combined components.

What is essential in the solution according to the invention defined by claim 1 is that the preload introduced via the door opener latch acts on the interaction of the components X and Y. The preload effect also occurs in particular on the spring, which resiliently connects the first element of component X and the second element of component X. The preload determines the displacement of the first element of component X relative to the second element of component The first element of component X is in stop position with component Y, and the second element of component X is out of stop position Component Y is, or the second stop position, in which the second element of component X is in contact with component Y. This second stop position represents a mechanically blocked stop position due to the design of the stop in conjunction with the second element of component is. In contrast, the first stop position represents a stop position that can be released by electrically releasing the electrically switchable locking device due to the design of the stop in conjunction with the first element of component

This preferably applies to each pair of components X and Y formed according to alternatives No. 1 to No. 8. The interacting components and on the other hand by the pre-load introduced from outside via the door opener latch, depending on the level of the pre-load, i.e. whether it is in the mentioned first area or in the mentioned second area.

The components X and Y are preferably components that interact directly in pairs. The components are preferably connected in a line and/or in series with one another and are preferably each movable, preferably rotatably mounted, in the door opener housing. The components are preferably designed in such a way that the component each interacts with a region, preferably with one end, with the component adjacent on one side and with another area, preferably with a different end, interacts with the component adjacent on the other side.

The three or four components mentioned in claim 1 do not have to be exhaustive in terms of their number in the embodiments according to the invention. This means that there can be more than three or four such components in the different versions, or even fewer than three or four. Accordingly, the number of alternatives No. 1 to No. 8 mentioned in claim 1 is not exhaustive. It is essential that the armature is a component that interacts on one side with the electrically switchable locking device and on the other side with the change, it can also be provided that a gear is connected between the electrically switchable locking device and the armature, and that a gear is connected between the armature and the change. These intermediate gears can each form an independent additional component or can also be understood as part of the armature or as part of the change. The same applies to the door opener latch. This is also to be understood as a component. This interacts on one side with the change or an intermediate gear and on its other side, preferably its outside, it interacts with the lock latch or the like while absorbing the preload acting from the outside.

As far as the gearbox is concerned, which is expressly optionally interposed between the change and the door opener latch: This can be understood as just one component or as several separate components that interact with each other. If the transmission is formed, for example, from a lever with a roller rotatably mounted on it, this structural unit consisting of lever and roller can be understood as a common, combined component or the lever as one component and the role as another component, namely as a subcomponent. The same applies to the transmissions discussed above, which in possible embodiments may be connected between the armature and the change or between the electrically switchable locking device and the armature or form part of the armature or the change. Depending on the division into more or fewer components, the number of alternatives No. 1 to No. 8 is increased or reduced accordingly.

Merely as an example, it should be mentioned that the expressly optionally provided gear between changeover and door opener latch consisting of a lever with a roller mounted on it makes a pairing possible in which the lever is designed as component X and the roller as component Y and, for example, according to the invention the lever consists of two resilient interconnected lever elements; or also makes a further pairing possible, in which the roller is designed as component X and the lever as component Y and, for example, the roller is designed according to the invention as a resiliently mounted roller; or makes a further pairing possible, in which the role is designed as component or also makes a further pairing possible, in which the lever is designed as component or makes a further pairing possible, in which the door opener latch is designed as component

The terms “first element of component X” and “second element of component a section of the body that is movably connected to the separate body, for example. The “elements of component X” within the meaning of claim 1 are therefore not necessarily different separate bodies of component X. This applies to the “first element of component X” and also to the “second element of component X”.

In any case, it is essential that these two elements of component X interact with component Y and that features i), ii) and iii) of claim 1 are fulfilled. It is particularly important that the two elements of component X are directly or indirectly connected to one another in a resilient manner.

This occurs depending on the amount of preload in conjunction with the spring force of the resilient connection mentioned. The first element of component not spent in a protruding position.

It is essential that the stop surfaces that cooperate in the first stop position are designed in such a way, preferably with regard to their angular arrangement, which determines the direction of introduction of their forces acting in the stop position, that the stop position can be released by electrically releasing the electrically switchable locking device.

In particularly preferred embodiments, this second stop position is realized in that a stop surface is formed on the second element of component /or interact by applying force to the stop surfaces in a direction that reinforces the blocking in the stop position.

These configurations of the stop surfaces in the second stop position include a mechanical self-locking which is so great that the stop position cannot be released simply by electrically releasing the electrically switchable locking device.

The exemplary embodiments shown in the figures are electric door openers for installation in a stationary door frame in a door in a building.

When installed, the door openers interact with a lock latch of a lock mounted on or in the door leaf of the door. The door leaf can, as is often the case in the practice of using door openers, be a revolving door leaf with a vertical revolving door axis, preferably a stop revolving leaf. To interact with the lock latch, the door opener has a door opener latch on the output side, which is controlled via an electrically switchable locking device of the door opener.

The door opener latch is designed as a pivoting door opener latch 1 in the exemplary embodiments of the door opener shown in the figures. In the usual installation position on swing doors with a vertical door axis, the axis of rotation 1q of the door strike 1 is aligned vertically.

The basic structure of the first exemplary embodiment

The first exemplary embodiment is in the Fig. 1 , ie in the Fig. 1a , 1a1 , 1a2 , 1b , 1b1, 1b2 , 1.2; 1.3 and 1.4 shown. The door opener has a door opener housing 2 in which the components of the door opener are stored. The door opener housing 2 is designed as a storage and receiving frame for the door opener components. The main components of the door opener are, in addition to the door opener latch 1, an electrically switchable locking device 3, an armature 4 and a change 5 connected between the armature 4 and the door opener latch 1. In the first exemplary embodiment shown, the change 5 works with the door opener latch 1 via an intermediate gear unit 6 together.

The axis of rotation 1q of the door opener latch 1 is aligned in the longitudinal direction of the door opener housing 2 in the illustrated embodiment and is arranged in the door opener housing in such a way that the door opener latch 1 is arranged on the front lateral edge of the door opener housing 2. The actuator of the electrically switchable locking device 3 is designed in the first exemplary embodiment shown as an electromagnet 3ht with a coil 3sp. The door opener is a closed-circuit door opener. With energized electromagnets 3ht, the armature 4 is attracted to the coil 3hs of the electrically switchable locking device and in this position - Locked position - held. By switching off the current, the armature 4 is switched to the release position. In the release position, the armature 4 is no longer attracted by the coil.

The anchor of the first embodiment

The anchor 4 is in the overall view Fig. 1a and 1b shown installed in the door closer. The Fig. 1.3 shows the anchor 4 in individual view. In this exemplary embodiment, the armature is designed as a two-armed lever, which interacts with one arm 4s with the coil 3sp of the holding magnet 3ht and with its other arm 4w with the change 5.

In the first exemplary embodiment shown, the anchor 4 is a one-piece anchor. It has no parts that can be moved relative to one another and are resiliently connected to one another.

The lever arm 4s that interacts with the coil 3sp is designed as a long lever arm and the lever arm 4w that interacts with the change 5 is designed as a shorter lever arm. As best shown in the individual illustration of the anchor 4 in Fig. 1.3 can be seen, the two lever arms of the anchor 4 form a right angle. The anchor axis of rotation 4q is formed in the apex area slightly offset from the apex. It runs in the door opener assembly in the door opener housing, as shown in the Fig. 1a and 1b can be seen, offset perpendicular to the axis 1a of the door opener latch 1. A return spring 4rf acts on the outside of the short lever arm 4w, which is supported on the housing and, in the drawing, acts on the armature in a clockwise direction in the direction of the coil 3sp.

The long lever arm 4s of the armature, which interacts with the coil 3s, has a contact surface facing the coil, which is attracted by the coil when the coil is energized. In the tightened position, the long lever arm 4s of the armature rests with its contact surface on the coil 3sp. In this position the anchor is in its locked position. It is held in this position as long as the coil is energized.

The short lever arm 4w of the anchor has a roller 4r mounted in the body of the lever arm 4w on its end face facing the change. Like from the Fig. 1 a1 and 1 b1, a blocking stop surface 4aa is formed axially above the roller 4r on the end face of the end face, which is assigned to a blocking stop surface 5aa formed on the change 5 and the lateral surface of the roller 4r forms a stop surface 4ii, which is a stop surface formed on the change 5 5ii is assigned. The interaction of these stop surfaces of the anchor with the assigned stop surfaces on the change is explained in detail below. First of all, the exact design of the change will be described.

It should be noted that in the design of the anchor 4 in the first exemplary embodiment described here, it is essential that the roller 4r is not resiliently mounted in the body of the lever arm 4w, but in a pivot bearing that is fixed to the body of the lever arm 4w. The anchor 4 is therefore not a multi-part anchor in the sense of the present invention.

The change of the first exemplary embodiment

The change 5 used in the first exemplary embodiment is in the installed door opener in the overall views of the door opener Fig. 1a and 1b and in individual representation in the Fig. 1.2 and 1.2.1 shown. In the exemplary embodiment, the change 5 is a multi-part change, that is, in the case of the first exemplary embodiment, it is composed of two bodies in several parts, namely a first body and a second body, which are resiliently connected to one another in that one body is resiliently mounted on the other body . The first body is hereinafter referred to as internal change 5i and the second body is subsequently referred to as external change 5a. The external change 5a forms the main body of the change 5. It has an elongated housing-like body 5g with a U-cross section, which is mounted as a two-armed lever with an axis of rotation 5q in the door opener housing. This axis of rotation 5q forms the axis of rotation of the change. The elongated housing-like body 5g is arranged along the longitudinal extent of the door opener housing 2 and parallel to the door opener latch 1 in the housing. The axis of rotation 5q is directed perpendicular to the axis of rotation 1q of the door opener latch 1 and perpendicular to the axis of rotation 4q of the anchor 4. The axes are offset from each other so that the axes do not intersect.

The elongated body 5g of the two-armed lever 5ah has a hook-shaped end at its end facing away from the armature 4, for interaction with the gear 6 interposed between the change 5 and the door opener latch 1. In modified exemplary embodiments, in which the change 5 directly with the Door opener latch interacts, i.e. an intermediate gear 6 is not present, the hook-shaped end of the body 5g interacts directly with the door opener latch 1.

In the elongated housing-like base body 5g of the external change 5a, the inner change 5i is resiliently supported on a spring device 5if used. The internal change 5i is formed by a two-armed lever. The spring device 5if has a helical compression spring. The axis of rotation 5iq of the two-armed lever is arranged parallel to the axis of rotation of the change 5q. The elongated base body 5g of the external change is arranged in the door opener housing 2 so that its open side faces the anchor 4. Here, the internal change is accommodated in the section of the housing-like base body, which forms the lever arm that interacts with the anchor 4. The pivot bearing with the axis of rotation 5iq of the internal change is arranged transversely to the U-legs of the housing-like base body. The two-armed lever forming the internal change 5i has a lever arm 5iw, which faces the armature 4 and cooperates with it, and a lever arm facing away from the armature 4, which interacts with the spring device 5if.

The spring device 5if has an adjusting device for adjusting the spring preload. For this purpose, a recess is formed in the lever arm of the internal change 5i facing away from the anchor, which is penetrated by a bearing pin which stands up from the bottom of the housing-like base body 5ah and is rigidly connected to it. An adjusting screw 5ifs is screwed into the bearing pin. The helical compression spring of the spring device 5if is mounted coaxially on the bearing pin in such a way that its lower end is supported on the top of the lever arm of the internal change 5i facing away from the anchor and its upper end is supported on a locking washer which is on the underside of the head of the adjusting screw 5ifs is present. The preload of the spring device 5if can be variably adjusted by turning the adjusting screw.

For interaction with the anchor 4, the change 5 has a stop surface 5ii on the inner change 5i and a blocking stop surface 5aa on the outer change 5a. The stop surface 5ii on the inner change 5i is formed on the free end of the two-armed lever which forms the inner change 5i and faces the anchor 4. The blocking stop surface 5aa on the outer change 5a is formed on the end face of the free end of the outer change 5a, which is arranged adjacent to the stop surface 5ii formed on the inner change 5i.

The stop surface 5ii on the inner change 5i cooperates with the associated stop surface 4ii on the anchor 4, which in the first exemplary embodiment is formed on the lateral surface of the anchor roller 4r. The interaction of these stop surfaces 5ii and 4ii takes place in a first stop position between change 5 and anchor 4 (see. Fig. 1a1 combined with Fig. 1.3 ). This is a stop position that can be released by unlocking the electrically switchable locking device 3. This stop position will be explained in more detail below.

The interaction of the blocking stop surface 5aa on the external change 5a with the blocking stop surface 4aa on the anchor takes place in a blocking stop position (see. Fig. 1 b1 in connection with Fig. 1.3 ). This cannot be solved by unlocking the electrically switchable locking device 3.

The interaction of anchor 4 and change 5 during operation of the door opener and the resulting two stop positions, namely the first stop position of the stop surfaces 5ii and 4ii and the stop position of the blocking stop surfaces 5aa and 4aa, which forms a blocking stop position, is described below:
If the electrically switchable locking device 3 is in the locking position and a preload is introduced into the door opener latch 1 from outside, in the sense of opening the door, a stop position results between the armature 4 and the change 5. What is essential here is that there are two different stop positions can be obtained, depending on how high the preload introduced into the door strike latch is. A distinction must be made between two preload ranges, namely a first preload range up to a predetermined maximum permissible preload and a preload range in which the preload is higher than the predetermined maximum permissible preload.

When a preload is applied, which lies in the first area, a stop position is established between the change 5 and the anchor 4, in which only the inner change 5i is in contact with the anchor 4, i.e. only the stop surface 5ii of the inner change 5i is in stop stands with the assigned stop surface 4ii of the armature 4. Due to the design and mutual arrangement of the abutting surfaces 5ii and 4ii, this stop position can be released by electrically disconnecting the electrically switchable locking device 3.

When a preload is applied that is in the second range, that is to say a preload that is above the predetermined maximum permissible value, in addition to the stop position of the inner change 5i and the anchor 4 just described, there is also a stop position between the outer change 5a and the anchor 4 a. This is the blocking stop position already mentioned, in which the blocking stop surface 5aa of the outer anchor 5 is in contact with the associated blocking stop surface 4aa of the anchor 4, which is a so-called blocking stop which cannot be solved by electrically disconnecting the electrically switchable locking device 3.

In the blocking stop position of the blocking stop surfaces 5aa and 4aa, there is a mechanical blocking in the sense of self-locking with friction and/or positive locking due to the mutual engagement of the surfaces. This can be done by appropriate angular alignment of the surfaces standing on top of each other and/or by corresponding complementary positive fit of the surfaces standing on top of each other.

In contrast to this, in the first stop position, in which only the stop surface 5ii of the internal change 5i is in contact with the stop surface 4ii of the anchor 4 and the blocking stop surfaces 5aa and 4aa are out of stop, such a self-locking mechanical blocking is not present. This stop position, which is in Fig. 1a1 is shown, can be released by switching the electrically switchable locking device 3 in its release position, ie the stop surfaces 5ii and 4ii come out of engagement when the electrically switchable locking device 3 is released solely under the effect of the acting preload. This is the essential difference to the blocking stop position of the blocking stop surfaces 5aa and 4aa, which are in the Fig. 1 b1 is shown. In this stop position, not only are the stop surfaces 5ii and 4ii in stop, but in particular also the blocking stop surfaces 5aa and 4aa.

The gearbox switched between the change and the door opener latch

The one in the Fig. 1 to 3 illustrated first exemplary embodiment between the change 5 and the door opener latch 1 Gear 6, which is also referred to here as "gear unit 6", can, as already mentioned above, be omitted in modified exemplary embodiments and the change 5 then interact directly with the door opener latch 1. In the first exemplary embodiment shown in the figures, this gear unit 6 is formed by a one-armed lever 6h, on the lever arm of which a roller 6r is mounted. The axis of rotation 6q of the lever 6h is arranged in a bearing of the door opener housing, as can be seen from the overall view in FIGS. 4.1a and 4.1b, parallel to the axis of rotation 5q of the change and opposite this axis of rotation and the axis of rotation 1q of the door opener latch 1, which runs perpendicular thereto and the axis of rotation 4q of the anchor 4, which also runs perpendicular thereto, so that the axes of rotation do not intersect. The roller 6r cooperates with the hook-shaped end of the change 5, which is formed on the end of the external change 5a facing away from the anchor 4. The interaction of the gear 6 with the door opener latch 1 occurs in that the cam-shaped outer contour of the lever 6h interacts with a complementary contour of the door opener latch.

In the modified embodiments not shown in the figures, in which the change 5 interacts directly with the door opener latch 1, corresponding contours for the interaction of the change 5 with the door opener latch 1 are possible, as are known per se in door openers of the prior art .

The second embodiment

In the Fig. 2 , 2a and 2b a second exemplary embodiment is shown. This embodiment differs from that described previously first embodiment of the Fig. 1 in that in the second exemplary embodiment the anchor 4 is designed as a multi-part anchor in the sense of the invention and the change 5 is designed in one piece. The multi-part anchor 4 consists of an outer anchor 4a and an inner anchor 4i which is resiliently mounted thereon. The inner anchor 4i is formed by a roller 4ir which is resiliently mounted on the short lever arm of the outer anchor 4a. The resilient mounting of the roller 4ir makes the anchor 4 in the second exemplary embodiment described here a "multi-part" anchor in the sense of the invention, consisting of an outer anchor and an inner anchor, which are resiliently connected to one another.

The external anchor 4a is designed as a two-armed lever which has a short lever arm 4w facing the change 5 and a long lever arm 4s which interacts with the holding magnet 3ht. The outer anchor 4a has the same basic configuration as the one-piece anchor 4 of the first exemplary embodiment. It consistently has the long lever arm 4s and the short lever arm 4w, which are arranged perpendicular to one another. The long lever arm 4s interacts via its contact plate in the same way as in the first exemplary embodiment with the holding magnet 3ht of the electrically switchable locking device 3. The door opener is designed as a closed-circuit door opener with the holding magnet 3ht in the same way as the door opener of the first exemplary embodiment.

The short lever arm 4w of the anchor facing the change 5 interacts with the change 5. The main difference is that in the second exemplary embodiment Fig. 2 , 2a and 2b the anchor 4 is made up of several parts, in that the inner anchor 4i formed by the roller 4ir is resiliently supported on or in the short lever arm 4w of the outer anchor 4a. The role 4ir is in one Receiving recess open on the front side is accommodated in the short lever arm 4w of the outer anchor 4a and is slidably mounted with its axis ends in opposite elongated holes in the wall of the receiving recess. The spring device 4if, designed as a helical compression spring, is accommodated in the receiving recess. This is supported with one end on the closed end of the receiving recess and with its other end on the roller 4ir. The receiving recess is open on the side facing the change, so that the resiliently mounted roller 4ir forming the inner anchor 4i can interact with the change 5.

In this second exemplary embodiment, the change 5 is, as already mentioned, designed as a one-piece change, i.e. it does not have a spring-loaded internal change. In the basic configuration, however, the change 5 is designed as a two-armed lever in accordance with the change 5 of the first exemplary embodiment. The axis of rotation 5q of the change 5 is the same as in the first exemplary embodiment, perpendicular to the axis of rotation 4q of the anchor 4 and perpendicular to the axis of rotation 1q of the door opener latch 1, and is offset from all other axes of rotation in such a way that the axes do not intersect.

The change 5 interacts in the same way as in the first exemplary embodiment at its end facing away from the armature 4 with a gear unit 6, which is connected between the door opener latch and the change 5. The gear unit 6 and the end of the change 5 that interacts with it are designed in the same way as in the first exemplary embodiment and can also be omitted in modified versions, as in the case of the modifications of the first exemplary embodiment.

How best from the Figs. 2a and 2b As can be seen, the lever end of the one-piece change 5 assigned to the anchor 4 in the second exemplary embodiment has two rigid stop surfaces 5ii, 5aa arranged next to one another. The stop surface 5ii, which interacts with the lateral surface of the resiliently mounted roller 4ir of the armature 4, is formed at the free end of the lever arm of the lever 5. It protrudes from the blocking stop surface 5aa of the change 5, which is also formed on this lever end of the change 5 adjacent to the stop surface 5ii. The lever end of the change 5 is essentially L-shaped, with the stop surface 5ii being formed on the front end of the protruding short L-leg and the blocking stop surface 5aa being formed on the inside of the long L-leg.

Regarding the mutual assignment of the stop surfaces and blocking stop surfaces and the stop positions:
The stop surface 5ii formed on the change 5 is assigned to the stop surface 4ii formed on the inner anchor 4i. This stop surface 4ii is formed by the outer surface of the resiliently mounted roller 4ir.

The blocking stop surface 5aa formed on the change 5 is assigned to the blocking stop surface 5aa formed on the outer anchor 4.

The stop position of the inner anchor 4i with the change 5 is in Fig. 2a shown. In this stop position, the stop surfaces 4ii and 5ii are in mutual contact.

The stop position of the external anchor 4a with the change 5 is in Fig. 2b shown. In this stop position, which is designed as a blocking stop position, the blocking stop surfaces 4aa and 5aa also stop against each other.

When in the stop position Fig. 2a the blocker stop surfaces 4aa and 5aa of the change and external anchor are not in mutual engagement. They are arranged at a distance from each other. Only the stop surface 4ii formed on the lateral surface of the spring-mounted roller 4ir and the associated stop surface 5ii on the change 5 are in this stop position ( Fig. 2a ) in mutual contact. This stop position can be released by electrically releasing the electrically switchable locking device 3. This stop position only occurs if, when the locking device is energized, the preload acting on the door latch 1 is less than or equal to the predetermined maximum permissible preload. The situation in this stop position Fig. 2a is the same as the corresponding stop position in Fig. 1a of the first embodiment.

In the Fig. 2b shown blocking stop position, in which in addition to the stop position described above Fig. 2a Even the blocking stop surfaces 4aa and 5aa formed on the outer anchor 4a and on the change 5 are in mutual abutment cannot be released by electrically releasing the electrically switchable locking device 3. The blocking stop position in Fig. 2b only occurs if the preload acting on the door strike latch is above the permissible maximum preload when the locking device is switched to the locking position. In this respect and what concerns the design and interaction of the blocking stop surfaces 4aa and 5aa, this applies corresponding to that described for the blocking stop position of the first exemplary embodiment.

The third embodiment

That in the Fig. 3 , 3a and 3b The third exemplary embodiment shown differs from the first exemplary embodiment Fig. 1 essentially in that the third exemplary embodiment is designed as a working current door opener. The change 5 is designed as a multi-part change. This is identical to the first exemplary embodiment Fig. 1 educated. The anchor 4 is designed in one piece, the same as in the first exemplary embodiment, but is designed differently in terms of its construction and arrangement.

The difference in the design as a working current door opener is realized in the third exemplary embodiment in that the actuator of the electrical locking device 3 is designed as a lifting magnet 3hb with a plunger 3st. When the electrical locking device 3 is energized, the plunger 3st is extended into its release position into a stop position with the armature 4 and thereby acts on the armature 4 in the release position, namely in the sense of a displacement of the armature 4 into its release position and holds the armature 4 in the release position as long as the current supply is maintained. In this exemplary embodiment, the anchor 4 is designed as a one-armed lever. The axis of rotation 4q is formed in the housing parallel to the axis of rotation 5q of the change 5, specifically offset from the axis of rotation 5q of the change and also offset from all other axes of rotation, so that the axes of rotation do not intersect.

The anchor 4, designed as a one-armed lever, has a plate-shaped lever arm which interacts with the multi-part change 5. The multi-part change 5 is, as I said, structurally identical to that of the first exemplary embodiment, i.e. with a resiliently mounted internal change 5i and an external change 5a.

In the first stop position, which is in Fig. 3a is shown, only the stop surface 5i of the internal change 5i interacts with an assigned stop surface 4ii of the anchor 4. The inner change 5i engages with its stop surface 5ii on the assigned stop surface 4ii of the anchor 4. The blocking stop surface 5aa formed in the external change 5a is not in contact with the associated blocking stop surface 4aa in this position.

The blocking stop surface 4aa is adjacent to the end face of the plate-shaped body of the anchor 4 in the direction parallel to the axis of rotation 4q, namely adjacent to the stop surface 4ii, which is also formed on the end face of the plate-shaped body.

In the Fig. 3a As in the exemplary embodiment described above, the first stop position shown is only obtained if, in the blocking position of the electrically switchable locking device 3, the preload acting on the door opener latch 1 is below the predetermined maximum preload.

The blocking position of the electrically switchable blocking device 3 is switched on in the exemplary embodiment designed as a working current door opener when the electrical actuator is not energized, ie the lifting magnet 3hb is not is energized and therefore the plunger 3st is not extended. By switching the electrically switchable locking device 3, ie by energizing the solenoid 3hb, the plunger 3st is then extended and the armature 4 is thereby acted upon in a clockwise direction about its axis of rotation 4q in the drawing. Due to the angular alignment of the stop surfaces 4ii and 5ii, which interact with one another in this stop position and are formed on the inner change 5i or the armature 4, when the armature 4 is acted upon by the plunger 3st, the stop position is released by pivoting the armature 4 in the graphic representation clockwise. However, this release of the stop position only occurs as long as the electrically switchable locking device 3 is energized and the preload is below the predetermined maximum preload.

In the Fig. 3b The blocking stop position shown only occurs when the preload introduced into the door opener latch 1 is greater than the predetermined maximum permissible preload and the lifting magnet 3hb is not energized, ie the electrically switchable locking device 3 is in its locking position. If the electrically switchable locking device 3 is switched by switching on the power supply, the plunger 3st is extended. The blocking stop position in Fig. 3b However, this cannot solve the problem. In the blocking stop position, the blocking stop surfaces 4aa and 5aa interact in the same way as in the previously described exemplary embodiments. These blocking stop surfaces 4aa and 5aa act in addition to the previously described stop position of the stop surfaces 4ii and 5ii and ensure that the armature 4 cannot be moved out of its blocking stop position by extending the plunger by energizing the lifting magnet 3hb. The blocking stop position can only be released occur when the preload acting on the door opener latch 1 is reduced to such an extent that it no longer exceeds the maximum permissible preload.

Fourth embodiment

This in Fig. 4 The fourth exemplary embodiment shown differs from the third exemplary embodiment in Fig. 3 only in that in the fourth exemplary embodiment the actuator of the electrically switchable locking device 3 is designed as an electric motor 3m with an electrically linearly extendable output member 3sm with a return spring 3sf acting in the retraction direction. The change 5 is the same as in the exemplary embodiment in Fig. 3 designed as a multi-part change with internal change 5i and external change 5a, which is also structurally the same as in the exemplary embodiment in Fig. 3 . The anchor 4 in the exemplary embodiment in Fig. 4 is also designed as a one-armed lever with a plate-shaped lever arm. The axis of rotation 4q of the armature relative to the other axes of rotation in the door opener housing 1 is also the same as in the exemplary embodiment in Fig. 3 . The return spring 3sf interposed between the armature 4 and the thrust member 3sm ensures that the thrust member 3sm is reset under the spring action when the electric motor is no longer energized.

The anchor 4 in the exemplary embodiment in Fig 4 has the same as the anchor 4 of the exemplary embodiment in Fig. 3 a stop surface 4ii and a blocking stop surface 4aa. These are formed in the same way on the front side of the lever arm of the anchor 4 as in the exemplary embodiment in Fig. 3 and also interact in the same way with the stop surface 5ii of the inner change 5i and the blocking stop surface 5aa of the outer anchor 5a. The output link can be extended linearly by 3m via the electric motor 3sm interacts with a tongue that protrudes at the front of the plate-shaped body of the anchor 4. At the in Fig. 3 In the exemplary embodiment shown, the tongue which interacts with the plunger 3st is formed on the underside of the plate-shaped body of the anchor 4.

The stop position in which the stop surface 4ii of the anchor 4 is in abutment with the stop surface 5i of the inner change 5i and the blocking stop position in which, in addition to this stop position of the stop surfaces 4ii and 5ii, the blocking stop surface 4aa of the anchor 4 is also in contact with the blocking stop surface 5aa of the outer anchor 5a Blocking stop is present in the exemplary embodiment Fig. 4 in the same way as in the exemplary embodiment in Fig. 3 . The electrically extendable thrust member 3sm of the electric motor 3m acts in the exemplary embodiment in Fig. 4 same as the plunger 3st of the lifting magnet 3hb in the exemplary embodiment in Fig. 3 .

The fifth embodiment

The in Fig. 5 The multi-part change 5 shown is intended for use in door openers that have a structure like the previous exemplary embodiments, in which a multi-part change 5 is used.

The multi-part change 5 in Fig. 5 has an external change 5a and an internal change 5i. The external change 5a is designed as a lever with an axis of rotation 5aq. It has a receiving recess 5an on its lever arm 5aw, which interacts with the anchor 4, not shown, in which the internal change 5i is arranged. In the exemplary embodiment shown, the internal change 5i is designed as a separate body, namely as a one-armed lever, which is in the receiving recess in one there arranged pivot bearing is rotatably mounted about the axis of rotation 5iq. In this exemplary embodiment, the internal change 5i is supported by a separate spring device 5if. The spring device 5if is designed here as a helical compression spring, which is supported in the receiving recess 5an between the underside of the inner change 5i and the bottom of the receiving recess. The external change 5a has an active edge for interaction with a gear 6, not shown, or for direct interaction with the door opener latch 1. If the external change 5a is designed as a two-armed lever, this active edge can preferably be formed on the lever arm facing away from the anchor 4 at the end of this lever arm. If the external change 5a is designed as a one-armed lever, the active edge can be designed, for example, on the side of the lever arm facing away from the anchor. A stop surface 5ii is formed on the inner change 5i, which is assigned to a stop surface 5ii, not shown, on the anchor 4, not shown. The internal change 5i can be retracted into the recess under the action of the anchor, not shown, against the force of the spring device 5if. Otherwise, the interaction of the anchor and the change in connection with the two stop positions is the same as in the previously described exemplary embodiments with a multi-part change and a one-piece anchor.

In the exemplary embodiment in Fig. 5 the inner change 5i also has a stop surface 5ii, which is assigned to a stop surface 4ii, not shown, on the anchor, not shown, and the outer change 5a has a blocking stop surface 5aa, which is assigned to a blocking stop surface 4aa, not shown, on the anchor 4, not shown.

The sixth embodiment

The in Fig. 6 The multi-part change 5 shown represents a sixth exemplary embodiment. This exemplary embodiment differs from the fifth exemplary embodiment only in that the inner change 5i is designed as a leaf spring and is connected to the outer change 5a via a mechanical connecting device 5vb with a rivet connection, screw connection or welded connection, these Connection also forms the axis of rotation 5iq. In contrast to the fifth exemplary embodiment, no separate spring device 5if is required.

The seventh embodiment

At the in Fig. 7 The multi-part change 5 shown is a seventh exemplary embodiment, which differs from those in the 5 and 6 The only difference between the illustrated embodiments is that the inner change 5i and the outer change 5a are formed and connected in one piece, the inner change 5i being designed to be resilient, in such a way that the inner change 5i is connected to the outer change 5a via a connecting section which is made of spring-elastic material Material is formed. Additionally or alternatively, the lever arm of the internal change 5i itself can be made of spring-elastic material.
