Abstract

An electric door opener is described with a door opener latch (1) and an electrically switchable locking device (3) with an armature (4) and changeover (5). The door opener is designed in such a way that when the door opener latch (1) is subjected to a preload that is below or is equal to a predetermined preload, the first element (5i) of the changeover (5) is displaced into a stop position with the armature (4) through the interaction of the changeover (5) and armature (4) when the electrically switchable locking device (3) is in the blocking position can be released by electrically releasing the electrically switchable locking device (3), and that when the door opener latch (1) is subjected to a preload that is above the predetermined preload, due to the interaction of the changeover (5) and armature (4) in the locked position the electrically switchable blocking device (3), the second element of the changeover (5) is shifted into a stop position with the armature (4), which is mechanically blocked and cannot be released by electrically releasing the electrically switchable blocking device.

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 fail-safe door openers and fail-safe door openers.

In the case of the known fail-safe door opener, the electric actuator of the electrically controllable switching device is usually in the form of an electromagnet which interacts with an armature in the form of a lever. When the holding magnet is energized, the lever arm of the armature is pulled to rest on the coils of the holding magnet and the electrically switchable blocking device is held in the blocking position. Such quiescent current electric strikes 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 fail-safe door openers constructed in this way is that although they provide a high degree of preload release, the maximum holding force (breaking force) of the door opener is limited by the holding force of the holding magnet.

In known fail-locked door openers of the above construction, the electric actuator of the electrically switchable control device is designed, for example, as an electric lifting magnet, which controls the armature via a plunger. When the lifting magnet is energized, the armature is acted upon by the plunger in the release direction. Such fail-safe door openers are off, for example EP 3 199 728 B1 and EP 3 199 730 A1 known.

Fail-locked electric strikes of this design have a high level of force, but with only a purely mechanical blocking. The coil is only used for unlocking by energizing.

From the DE 10 2013 103 479 A1 a working current door opener with the features of the preamble of main claim 1 is known. The actuator of the electrical locking device is a lifting magnet. It works together with a locking anchor designed as a one-armed lever, which blocks the door opener latch in its locking position. The door opener in D1 has a so-called locking function. Locking function means that the door opener is unlocked at the moment the lifting magnet is energized by moving the locking anchor and the switch to their release position and remaining in this position via the locking function until the next access occurs via the door, i.e. until the door can be passed is opened via the door opener latch. The door opener trap in the DE 10 2013 103 479 A1 is a swing trap. For this purpose, it has a multi-part shaft which interacts with a locking lever and with an additional lever. A locking spring is connected between the locking lever and the additional lever. This is controlled by the lock latch. The locking spring blocks, as long as the door is not committed in the unlocked position, the door latch against a pivoting movement and at the same time keeps the exchange and the locking anchor in the unlocked position. This locking function is canceled by the action of the latch bolt on the locking spring when the door is entered.

From the DE 75 16 495 U a fail-safe electric strike with the features of the preamble of main claim 1 is also known. In the document, the actuator of the electrical locking device is also designed as a lifting magnet, which interacts with a pivoting armature. A blocking element is articulated on the pivoting armature and is connected in front of the pivoting armature. The locking element holds the pivoting armature in the spring-loaded only operating position in locking engagement with the changeover. In order to secure the engagement of the pivoting armature and change in this locked position against vibration and impact stress, there is a loading spring which acts on the pivoting armature in the direction of engagement. The loading spring is designed as a helical compression spring. In one embodiment variant, the spring is supported with its one end on the pivoting anchor and with its other end on the pivotable door opener latch. In the other embodiment variant, the spring is supported with its one end on the pivoting armature and with its other end directly on the housing of the door opener.

The object of the present invention is to create a door opener of the structure mentioned at the outset, which has good preload properties and, at the same time, high security against being forced open.

Expressed in general terms, the solution according to the invention provides that the components armature, changeover and door opener latch preferably connected in a line and/or in series or the components armature, changeover, gear unit and door opener latch or subcomponents of these preferably connected in a line and/or in series components at least one pair of directly interacting components X and Y is formed, which are designed as follows and interact as follows:

  • - Alternative No. 1: the pair of components X and Y is formed by the alternation as component X and the anchor as component Y
  or

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

The number of eight alternatives is not final, since it depends on the division of the components into sub-components and/or common, combined components.

What is essential in the solution according to the invention defined by claim 1 is that the initial load introduced via the door opener latch acts on the interaction of 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 X. Depending on the magnitude of the preload, the first or second stop position occurs when the electrically switchable locking device is in the locked position, i.e. the first stop position in which the first element of component X is in abutment with component Y, and the second element of component X is out of the abutment position of component Y, or the second abutment position in which the second element of component X is in abutment with component Y. Due to the design of the stop in connection with the second element of component X - preferably due to the design of the stop surfaces interacting in the position - this second stop position represents a mechanically blocked stop position, i.e. a stop position that cannot be released by electrically releasing the electrically switchable blocking device is. In contrast, the first stop position represents a stop position that can be released by electrically releasing the electrically switchable blocking device due to the design of the stop in connection with the first element of component X—preferably due to the design of the stop surfaces that interact in this position.

This preferably applies to each pair of components X and Y formed according to alternatives No. 1 to No. 8. The interacting components X and Y are each influenced on the one hand by the electrically switchable locking device, depending on whether it is in its locked position or in its release position and on the other hand by the initial load introduced from the outside via the door opener latch, depending on the magnitude of the initial load, i.e. whether it is in the first area mentioned or in the second area mentioned.

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 movably, preferably rotatably, mounted in the door opener housing. The components are preferably designed in such a way that the component interacts with one area, preferably with one end, in each case with the component adjacent on one side and with another area, preferably with another end, with the component adjacent on the other side.

In the embodiments according to the invention, the three or four components mentioned in claim 1 do not have to be final in terms of their number. I.e. there can also be more than three or four such components in the various designs, or fewer than three or four. Accordingly, the number of alternatives no. 1 to no. 8 mentioned in claim 1 is not final. 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 changeover, it also being possible for a gear to be connected between the electrically switchable locking device and the armature, and that a gearbox is connected between the anchor and the changeover. These interposed gears can each form an independent further component or can also be understood as part of the anchor or as part of the change. The same applies to the door opener latch. This is also to be understood as a component. This acts on one side with the changeover or an interposed gear and on its other side, preferably its outside, it works with the latch bolt or the like together, absorbing the preload acting from the outside.

As far as the gearbox, which is expressly optionally interposed between the changeover and the door opener latch, is concerned: this can be understood as just one component or as several separate components that interact with one another. If the gear mechanism is formed, for example, from a lever with a roller rotatably mounted on it, this assembly of lever and roller can be understood as a common, combined component or the lever as a component and the roller as a further component, namely in each case as a subcomponent. The same also applies to the gears discussed above, which in possible designs are connected between the armature and the changeover or between the electrically switchable locking device and the armature or form part of the armature or the changeover. Depending on the division into more or fewer components, the number of alternatives #1 through #8 is increased or decreased accordingly.

Merely as an example, it should be mentioned that the expressly optionally provided gear between the changeover and the 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 e.g. the lever according to the invention consists of two springs interconnected lever elements; or also makes another 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 spring-loaded roller; or makes another pairing possible, in which the roller is designed as component X and the change as component Y and e.g. the roller is designed according to the invention as a spring-loaded roller; or also makes another pairing possible, in which the lever is designed as component X and the door opener latch as component Y and, for example, the lever according to the invention consists of two lever elements which are resiliently connected to one another; or makes another pairing possible, in which the door opener latch is designed as component X and the lever as component Y and e.g. the door opener latch according to the invention consists of two door opener latch elements resiliently connected to one another.

The terms "first element of component X" and "second element of component X" are preferably to be understood as follows: The "element" can be a separate body or just a part of a separate body, e.g. a rigid portion of a separate body or just a portion of the body connected to the separate body, e.g. 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".

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

This solution according to the patent, in connection with the first element and the second element of component X and the two different stop positions, results in a two-stage nature of component X in terms of its effect or function.

The pairings of components X and Y according to alternatives no. 1 to no. 8 defined in claim 1 show that each of the components can represent the "multi-part" component X with the resiliently connected first and second element and also each of the components "One-piece" component Y may represent, where "one-piece" means that the component does not have such a first and second element.

A preferred further development can be implemented according to claim 2 . In this development according to claim 2, in general terms, it is provided that
that the first element of component X is arranged in the electrically releasable stop position in a projecting position relative to the second element of component X, so that of the two elements of component X only the first element of component X is arranged in the range of movement of component Y, and
that the first element of component X is arranged in the electrically non-releasable blocking stop position in a non-protruding position relative to the second element of component X, so that of the two elements of component X only the second element of component X or the second element of component X and the first element of component X in the range of motion of component Y is.

The basic idea of this development version defined by claim 2 is: through the action of the preload introduced via the door opener latch on the spring, which resiliently connects the first element of component X and the second element of component X, e.g. through a between the first and the second component X intermediate spring device or e.g. by a resiliently designed section of the first element of component X, the displacement of the first element of component X relative to the second element of component X in a protruding, i.e. protruding or overhanging position or in a non-protruding position spent. This takes place depending on the level of the preload in conjunction with the spring force of the resilient connection mentioned. Thus, the first element of component X is placed in the projected position in a first preload region and placed in the non-projected position in a second preload region. Due to the back-reference of claim 2, this further development according to claim 2 basically refers to claim 1 and in this respect always represents a further development of the subject-matter of claim 1 and applies to all alternatives No. 1 to No. 8.

Only as an example for the case of alternative no. 1 it should be noted that further training According to claim 2, for this case of alternative no Change only the first element of the component change is placed in the range of motion of the anchor component, and
that the first element of the component change in the electrically non-releasable blocking stop position is arranged in a non-projecting position relative to the second element of the component change, so that of the two elements of the component change only the second element of the component change or the second element of the component change Changeover and the first element of the Changeover component within the range of motion of the Anchor component is or are.

Only as an example for the case of alternative no. 2, it should be noted that the development according to claim 2 for this case of alternative no. 2 then specifically provides that the first element of the anchor component in the electrically releasable stop position relative to the second element of The Anchor component is placed in a protruding position, so that of the two Anchor component elements, only the first Anchor component element is located in the range of movement of the Alternating component, and
that the first element of the anchor component is arranged in the electrically non-releasable blocking stop position in a non-projecting position relative to the second element of the anchor component, so that of the two elements of the anchor component only the second element of the anchor component or the second element of the component Anchor and the first element of the Anchor component in the range of motion of the Change component is.

The same applies to the other alternatives no. 3 to no. 8.

This can be carried out particularly preferably if the first element of component X and the second element of component X are each designed as a separate component. The spring device can then advantageously be supported with its one end on the first element of component X and with its other end on the second element of component X. In preferred embodiments, the spring device can then be designed, for example, as a helical compression spring.

The second alternative implementation according to claim 3 provides that the first element of component X and/or a connecting section of the first element of component X to the second element of component X is at least partially resilient, preferably resilient.

In addition to the door opener latch 1, the main components of the door opener are an electrically switchable blocking device 3, an armature 4 and a switch 5 connected between the armature 4 and the door opener latch 1. In the first exemplary embodiment shown, the switch 5 acts with the door opener latch 1 via an interposed gear unit 6 together.

In the embodiment shown, the axis of rotation 1q of the door opener latch 1 is aligned in the longitudinal direction of the door opener housing 2 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 . In the illustrated first exemplary embodiment, the actuator of the electrically switchable locking device 3 is designed as an electromagnet 3ht with a coil 3sp. The door opener is a fail-safe door opener. When the electric holding magnet 3ht is energized, the armature 4 is attracted to the coil 3hs of the electrically switchable blocking device and is held in this position—blocking position. The armature 4 is switched to the release position by switching off the current supply. 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 in the 1a and 1b shown installed in the door closer. The 1.4 shows the anchor 4 in detail. 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 changeover 5.

The armature 4 in the illustrated first exemplary embodiment is a one-piece armature. It has no mutually displaceable parts that are resiliently connected to each other.

The lever arm 4s interacting with the coil 3sp is designed as a long lever arm and the lever arm 4w interacting with the changeover 5 is designed as a shorter lever arm. As best seen in the individual representation of the anchor 4 in 1.4 can be seen, form the two lever arms of the Anchor 4 a right angle. The armature axis of rotation 4q is formed in the apex region, slightly offset from the apex. It runs in the door opener arrangement in the door opener housing, as shown in the 1a and 1b can be seen, offset perpendicular to the axis 1a of the door latch 1. A return spring 4rf acts on the outside of the short lever arm 4w, which is supported on the housing and acts on the armature in the drawing clockwise 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 which faces the coil and is attracted by the coil when the coil is energized. In the attracted position, the long lever arm 4s of the armature rests with its contact surface on the coil 3sp. In this position, the armature is in its blocking position. It is held in this position as long as the coil is energized.

The short lever arm 4w of the armature has a roller 4r mounted in the body of the lever arm 4w on its end face facing the changeover. How from the 1 a1 and 1b1 As can be seen, 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 changeover 5, and the lateral surface of the roller 4r forms a stop surface 4ii, which is assigned to a stop surface 5ii formed on the changeover 5. The interaction of these stop surfaces of the armature with the associated stop surfaces on the exchange is explained in detail below. First of all, however, the exact design of the change will be described first.

It should be noted that in the design of the armature 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 which is fixed to the body of the lever arm 4w. The armature 4 is therefore not a multi-part armature within the meaning of the present invention.

The change of the first embodiment

The change 5 used in the first embodiment is in the built-in door opener in the overall views of the door opener in the 1a and 1b and in detail in the 1.2 and 1.3 shown. The change 5 is in the exemplary embodiment a multi-part change, ie in the case of the first exemplary embodiment composed of two parts, namely a first body and a second body, which are resiliently connected to one another by one body being resiliently mounted on the other body . The first body is hereinafter referred to as inside change 5i and the second body is hereinafter called outside change 5a. The outside 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 elongate, housing-like body 5g is arranged in the housing along the longitudinal extent of the door opener housing 2 and parallel to the door opener latch 1 . The axis of rotation 5q is directed perpendicularly to the axis of rotation 1q of the door opener latch 1 and perpendicularly to the axis of rotation 4q of the armature 4 . The axes are offset to each other so that the axes do not intersect.

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

In the elongate, housing-like base body 5g of the outer change 5a, the inner change 5i is inserted in a resilient manner, supported on a spring device 5if. The inside 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 main body 5g of the external switch is arranged in the door opener housing 2 in such a way that it faces the armature 4 with its open side. Here, in the section of the housing-like base body, which forms the lever arm interacting with the armature 4, the interior change is accommodated. The pivot bearing with the axis of rotation 5iq of the interior change is arranged transversely to the U-legs of the housing-like base body. The two-armed lever forming the interior change 5i has a lever arm 5iw which faces the armature 4 and interacts with it, and a lever arm which faces away from the armature 4 and which interacts with the spring device 5if.

The spring device 5if has an adjustment device for adjusting the spring preload. For this purpose, a recess is formed in the lever arm of the inner changeover 5i facing away from the armature, through which a bearing bolt extends, which protrudes upwards from the bottom of the housing-like base body 5ah and is rigidly connected thereto. There is a 5ifs set screw in the bearing pin screwed in. The helical compression spring of the spring device 5if is mounted coaxially on the bearing bolt in such a way that its lower end is supported on the upper side of the lever arm of the internal changeover 5i facing away from the armature and is supported with its upper end on a locking washer which is on the underside of the head of the adjusting screw 5ifs applied. The prestressing of the spring device 5if can be variably adjusted by turning the adjusting screw.

For the interaction with the armature 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 forming the inner change 5i, which faces the armature 4. The blocking stop surface 5aa on the outer change 5a is formed on the front side 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 interacts with the associated stop surface 4ii on the armature 4, which is formed on the lateral surface of the armature roller 4r in the first exemplary embodiment. These stop surfaces 5ii and 4ii interact in a first stop position between change 5 and armature 4 (see Fig. 1a1 combined with 1.4 ). This is a stop position that can be released by releasing the electrically switchable locking device 3 . This stop position is explained in more detail below.

The interaction of the blocking stop surface 5aa on the outside change 5a with the blocking stop surface 4aa on the armature takes place in a blocking stop position (see Fig. 1b1 combined with 1.4 ). This cannot be released by releasing the electrically switchable blocking device 3 .

• Wenn die elektrisch schaltbare Sperreinrichtung 3 in Sperrstellung steht und von außen eine Vorlast in die Türöffnerfalle 1, im Sinne einer Öffnung der Tür, eingeleitet wird, ergibt sich eine Anschlaglage zwischen dem Anker 4 und dem Wechsel 5. Wesentlich hierbei ist, dass zwei unterschiedliche Anschlagstellungen erhalten werden, abhängig davon wie hoch die in die Türöffnerfalle eingeleitete Vorlast ist. Es ist zwischen zwei Vorlastbereichen zu unterscheiden, nämlich einem ersten Vorlastbereich bis zu einer vorbestimmten maximal zulässigen Vorlast und einem Vorlastbereich, bei dem die Vorlast höher ist als die vorbestimmte maximal zulässige Vorlast.

The interaction of armature 4 and changeover 5 during operation of the door opener and the two stop positions that result, namely the first stop position of stop surfaces 5ii and 4ii and the stop position of blocking stop surfaces 5aa and 4aa, which forms a blocking stop position, is described below:

• If the electrically switchable blocking device 3 is in the blocking position and a preload is introduced into the door opener latch 1 from the outside in the sense of opening the door, there is a stop position between the armature 4 and the changeover 5. It is essential here that there are two different stop positions be obtained, depending on how high the initial load introduced into the door opener 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 acts that is in the first range, a stop position occurs between the change 5 and the armature 4, in which only the inner change 5i is in contact with the armature 4, i.e. only the stop surface 5ii of the inner change 5i is in contact stands with the associated stop surface 4ii of the armature 4. This stop position can be released due to the design and mutual arrangement of the contacting surfaces 5ii and 4ii by electrically releasing the electrically switchable blocking device 3.

When a preload acts that is in the second range, i.e. a preload that is above the predetermined maximum permissible value, there is also a stop position between the outside change 5a and the armature 4 in addition to the stop position of the inside change 5i and anchor 4 just described a. This is the blocking stop position already mentioned, in which the blocking stop surface 5aa of the outer armature 5 is in contact with the associated blocking stop surface 4aa of the armature 4, which is what is known as a blocking stop, which cannot be activated by electrically releasing the electrically switchable blocking device 3 is solvable.

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 frictional engagement and/or positive engagement through the mutual engagement of the surfaces. This can be done by appropriate angular alignment of the surfaces that are in contact with one another and/or by corresponding complementary positive locking of the surfaces that are in contact with one another.

In contrast to this, in the first stop position, in which only the stop surface 5ii of the inner change 5i is in contact with the stop surface 4ii of the armature 4 and the blocking stop surfaces 5aa and 4aa are out of the stop, such a self-locking mechanical blocking does not exist. This stop position, which in 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 disengage when the electrically switchable locking device 3 is released solely under the effect of the acting preload. This is the main difference to the blocking stop position Blocking stop surfaces 5aa and 4aa in the 1b1 is shown. In this stop position, not only are the stop surfaces 5ii and 4ii in stop position, but in particular also the blocking stop surfaces 5aa and 4aa.

The transmission switched between the change and the door opener latch

That at the in the 1 , ie in the 1a , 1 a1 , 1a2 , 1b , 1b1 , 1b2 , 1.2 ; 1.3 and 1.4 illustrated first embodiment between the exchange 5 and the door latch 1 interposed

Gear 6, which is also referred to as “gear unit 6” in the present case, can, as already mentioned above, also 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 in a bearing of the door opener housing, as can be seen from the overall view in FIGS 4.1a and 4.1b can be seen, arranged parallel to the axis of rotation 5q of the changeover and offset relative to this axis of rotation and the axis of rotation 1q of the door opener latch 1 running perpendicularly thereto and the axis of rotation 4q of the armature 4 also running perpendicularly 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 at the end of the outer change 5a facing away from the anchor 4. The interaction of the gear 6 with the door latch 1 takes place in that the cam-shaped outer contour of the lever 6h interacts with a complementary contour of the door latch.

In the modified exemplary 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 2 , 2a and 2 B a second embodiment is shown. This embodiment differs from the first embodiment described above 1 in that, in the second exemplary embodiment, the armature 4 is designed as a multi-part armature within the meaning of the invention and the changeover 5 is designed in one piece. The multi-part armature 4 consists of an outer armature 4a and an inner armature 4i resiliently mounted thereon. The inner armature 4i is formed by a roller 4ir spring-mounted on the short lever arm of the outer armature 4a. The resilient mounting of the roller 4ir makes the armature 4 in the second exemplary embodiment described here a “multi-part” armature within the meaning of the invention, consisting of an outer armature and an inner armature, which are resiliently connected to one another.

The outer armature 4a is designed as a two-armed lever, which has a short lever arm 4w facing the changeover 5 and a long lever arm 4s interacting with the holding magnet 3ht. The basic configuration of the outer anchor 4a is therefore the same as that of 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 each other. The long lever arm 4s interacts with the holding magnet 3ht of the electrically switchable blocking device 3 via its contact plate in the same way as in the first exemplary embodiment. The door opener is designed with the holding magnet 3ht in the same way as the door opener of the first exemplary embodiment as a fail-safe door opener.

The short lever arm 4w of the armature facing the change 5 interacts with the change 5. The main difference is that in the second embodiment of the 2 , 2a and 2 B the armature 4 is in several parts, in that the inner armature 4i formed by the roller 4ir is resiliently supported on or in the short lever arm 4w of the outer armature 4a. The roller 4ir is accommodated in a receiving recess open at the end in the short lever arm 4w of the outer anchor 4a and is slidably mounted with its axle ends in opposite elongated holes in the wall of the receiving recess. The spring device 4if designed as a helical compression spring is received in the receiving recess. This is supported with its one end on the closed front 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 spring-loaded roller 4ir forming the inner anchor 4i can interact with the change 5.

In this second exemplary embodiment, the changeover 5 is designed, as already mentioned, as a one-piece changeover, ie it has no spring-loaded inner changeover. In the basic configuration, however, the changeover 5 is designed as a two-armed lever, in accordance with the changeover 5 of the first exemplary embodiment. The axis of rotation 5q of the change 5 is the same as in the first embodiment, perpendicular to the axis of rotation 4q of the Anchor 4 and perpendicular to the axis of rotation 1q of the door latch 1, each offset to all other axes of rotation so that the axes do not intersect.

The change 5 acts in the same way as in the first exemplary embodiment at its end remote from the armature 4 with a gear unit 6 which is connected between the door latch and the change 5 . The transmission unit 6 and the end of the changeover 5 that interacts with it is 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 2a and 2 B As can be seen, the lever end of the one-piece changeover 5 assigned to the armature 4 has two rigid stop surfaces 5ii, 5aa arranged next to one another in the second exemplary embodiment. The stop surface 5ii cooperating with the lateral surface of the spring-loaded roller 4ir of the armature 4 is formed at the free end of the lever arm of the lever 5 . It projects in front of the blocking abutment surface 5aa of the change 5, which is also formed on this lever end of the change 5 adjacent to the abutment surface 5ii. The lever end of the changeover 5 is essentially L-shaped, with the abutment surface 5ii being formed at the front end of the protruding short L-leg and the blocking abutment surface 5aa being formed on the inside of the long L-leg.

• Die am Wechsel 5 ausgebildete Anschlagfläche 5ii ist der am Innenanker 4i ausgebildeten Anschlagfläche 4ii zugeordnet. Diese Anschlagfläche 4ii wird durch die Außenfläche der federnd gelagerten Rolle 4ir gebildet.

Regarding the mutual assignment of the stop surfaces and blocking stop surfaces and the stop positions:

• The stop surface 5ii formed on the exchange 5 is associated with the stop surface 4ii formed on the inner anchor 4i. This stop surface 4ii is formed by the outer surface of the spring-loaded roller 4ir.

The blocking stop surface 5aa formed on the exchange 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 2a shown. In this stop position, the stop surfaces 4ii and 5ii are in mutual abutment.

The stop position of the outer anchor 4a with the change 5 is in 2 B shown. In this stop position, which is designed as a blocking stop position, the blocking stop surfaces 4aa and 5aa are also in mutual abutment.

At the stop position in 2a the blocker stop surfaces 4aa and 5aa of the change and outer anchor are not in mutual engagement. They are spaced apart from each other. Only the stop surface 4ii formed on the lateral surface of the spring-loaded roller 4ir and the associated stop surface 5ii on the changeover 5 are in this stop position ( 2a ) in mutual attack. This stop position can be released by electrically releasing the electrically switchable blocking device 3 . This stop position only occurs if, when the locking device is energized, the initial load acting on the door latch 1 is less than or equal to the predetermined maximum permissible initial load. The situation in this stop position in 2a is the same as the corresponding stop position in 1a of the first embodiment.

In the 2 B Blocking stop position shown, in addition to the stop position described above 2a The blocking stop surfaces 4aa and 5aa formed on the outer anchor 4a and on the changeover 5 are also in mutual abutment, cannot be released by electrically releasing the electrically switchable blocking device 3 . The blocking stop position in 2 B only occurs when the preload acting on the door latch is above the maximum permissible preload when the locking device is switched to the locked position. Insofar as the design and the interaction of the blocking stop surfaces 4aa and 5aa are concerned, the same applies as described for the blocking stop position of the first exemplary embodiment.

The third embodiment

That in the 3 , 3a and 3b illustrated third embodiment differs from the first embodiment of the 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 1 educated. The armature 4 is designed in one piece in the same way as in the first exemplary embodiment, but is designed differently in terms of construction and arrangement.

The difference, which lies in the design as a working current door opener, is implemented 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 blocking device 3 is energized, the plunger 3st is extended into its release position in 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 in its Release position and holds the armature 4 in the release position as long as the energization is maintained. In this exemplary embodiment, the armature 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 to the axis of rotation 5q of the change and also offset to all other axes of rotation, so that the axes of rotation do not intersect.

The armature 4 designed as a one-armed lever has a plate-shaped lever arm which interacts with the multi-part change 5 . As already mentioned, the multi-part change 5 is structurally identical to the first exemplary embodiment, i.e. with a spring-loaded inner change 5i and an outer change 5a.

In the first stop position, which in 3a is shown, only the stop surface 5i of the inner change 5i acts together with an associated stop surface 4ii of the armature 4. The inner change 5i engages with its stop surface 5ii on the associated stop surface 4ii of the armature 4. In this position, the blocking stop surface 5aa formed in the outer change 5a is not in contact with the associated blocking stop surface 4aa.

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

In the 3a shown first stop position is obtained as in the previously described embodiment only if in the locking position of the electrically switchable locking device 3 acting on the door latch 1 preload is below the predetermined maximum preload.

The blocking position of the electrically switchable blocking device 3 is switched on in the embodiment designed as a working current door opener when the electric actuator is not energized, i.e. the lifting magnet 3hb is not energized and the plunger 3st is therefore not extended. By switching over the electrically switchable locking device 3, i.e. by energizing the lifting magnet 3hb, the plunger 3st is then extended and the armature 4 is thereby acted upon about its axis of rotation 4q in the clockwise direction 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 with a pivoting of the armature 4 in clockwise in the drawing. However, this release of the stop position only takes place as long as the electrically switchable blocking device 3 is energized and the preload is below the predetermined maximum preload.

In the 3b Blocking stop position shown only occurs when the initial load introduced into the door opener latch 1 is greater than the predetermined maximum permissible initial load and the lifting magnet 3hb is not energized, ie the electrically switchable locking device 3 is in its locked position. If now the electrically switchable blocking device 3 is switched over by switching on the current supply, the plunger 3st is extended. The blocking stop position in 3b however, cannot be solved by this. In the blocking stop position, the blocking stop surfaces 4aa and 5aa work together in the same way as in the exemplary embodiments described above. These blocking stop surfaces 4aa and 5aa act in addition to the previously described stop position of stop surfaces 4ii and 5ii and ensure that the armature 4 cannot be moved out of its blocking stop position when the plunger is extended by energizing the lifting magnet 3hb. The blocking stop position can only be released when the initial load acting on the door opener latch 1 is reduced to such an extent that it then no longer exceeds the maximum permissible initial load.

Fourth embodiment

This in 4 illustrated fourth embodiment differs from the third embodiment in 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 driven element 3sm with a return spring 3sf acting in the retracting direction. The change 5 is the same as in the embodiment in FIG 3 designed as a multi-part change with an inner change 5i and an outer change 5a, also structurally the same as in the embodiment in 3 . The armature 4 in the embodiment in 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 embodiment in FIG 3 . The restoring spring 3sf interposed between the armature 4 and the thrust element 3sm ensures that the thrust element 3sm is reset under the spring action when the electric motor is no longer energized.

The armature 4 in the embodiment in 4 has the same as the armature 4 of the embodiment in FIG 3 a stop surface 4ii and a blocking stop surface 4aa. These are formed on the end face of the lever arm of the armature 4 in the same way as in the embodiment in FIG 3 and also interact in the same way with the abutment surface 5ii of the inner exchange 5i and the blocking abutment surface 5aa of the outer anchor 5a. The driven element 3sm, which can be extended linearly via the electric motor 3m, interacts with a tongue which is designed to protrude at the end face of the plate-shaped body of the armature 4. At the in 3 illustrated embodiment, the tongue cooperating with the plunger 3st is formed on the underside of the plate-shaped body of the armature 4.

The stop position in which the stop surface 4ii of the armature 4 is in contact 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 armature 4 is also in contact with the blocking stop surface 5aa of the outer armature 5a in Blocking stop is, takes place in the embodiment in 4 in the same way as in the embodiment in FIG 3 . The electrically extendable thrust member 3sm of the electric motor 3m acts in the embodiment 4 the same as the plunger 3st of the lifting magnet 3hb in the embodiment in FIG 3 .

The fifth embodiment

the inside 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 5 has an outside change 5a and an inside change 5i. The external exchange 5a is designed as a lever with a pivot axis 5aq. On its lever arm 5aw, which interacts with the armature 4 (not shown), it has a receiving recess 5an, in which the inner change 5i is arranged. In the exemplary embodiment shown, the internal changeover 5i is designed as a separate body, namely as a one-armed lever which is mounted in the receiving recess in a rotary bearing arranged there so that it can rotate about the axis of rotation 5iq. In this exemplary embodiment, the inside 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 changeover 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 exchange 5a is designed as a two-armed lever, this active edge can preferably be formed on the lever arm facing away from the armature 4 at the end of this lever arm. If the outside 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 armature 4 (not shown). The interior change 5i can be moved into the recess counter to the force of the spring device 5if under the action of the armature (not shown). Otherwise, the interaction of the armature 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 armature.

In the embodiment in 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 inside 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 riveted connection, screw connection or welded connection 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 7 illustrated multi-part exchange 5 is a seventh embodiment, which differs from those in the 5 and 6 The only difference between the illustrated exemplary embodiments is that the inner change 5i and the outer change 5a are designed and connected in one piece, with the inner change 5i being designed to be spring-elastic, 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 spring-elastic material is formed. Additionally or alternatively, the lever arm of the interior exchange 5i itself can be made of resilient material.
