Lockable door opener by remote control with a stop device

The invention relates to a remote-controllable door opener with a stopping device according to the characteristics of the preamble of claim 1.

A lock release of this type is known from FR 2726847 A1. It discloses a door opener with a pivoting latch. A housing space for a stopping device is provided in the pivoting latch. The arresting device has a spring loaded pin which cooperates with a lock latch.

DE 696 17446 T2 shows a door opener with a pivoting latch comprising a latch base body with a bolting part and with a stop device. The arresting device is configured as a spring loaded pin which is movably received in the latch base body. By means of a pivoting lever disposed between the pin and a lock latch, the transmission of force beyond the area of movement of the bolting part from the lock bolt to the pin is ensured.

In practice such arresting devices are used in electric lockers to ensure that the door closed after electric activation of the electric lock can be opened, even when the electrical actuation of the electric lock is no longer carried out. As a result, for example, a door transit delayed in time is possible. Particularly in nursing homes and hospitals, a doorway for people with mobility limitations can be made possible in a comfortable way.

Document DE 1138334 A shows an electric door opener with pivoting door opener latch. In the region of the lock release latch, a spring-loaded pin cooperates through a compression spring and a leaf spring with a lock-release bar to stop it in the released position. After the power supply of the door opener the bar is released and can be moved to a released position. In the released position, the bar is held by the spring-loaded pin in which this pin rests with one end against the door opener bar and with the other end on a lock bolt. If now the door is opened then the lock release latch is pivoted and the stop pin is disengaged from the lock latch. Then the compression spring as well as the leaf spring can be loosened, so that the bar is no longer applied to the released position.

Document DE 102006 013 033 A1 shows an electric door opener with a spring loaded pin, which passes through the door opener latch and cooperates with a pivotable holding element for holding the opener in a released position.

The object of the present invention is to create a door opener operable by remote control with a stop device having a simple construction structure and, nevertheless, present a high safety in operation. Preferably the stopping device must be able to be retrofitted in a simple manner.

This object is solved according to the invention by means of a remote-controllable door opener with a stop device with the features of claim 1.

According to the invention, it is provided that the arresting device has a stop body, which at one end accommodates a stop pin displaceably and at its opposite end a pressure pin in an axial direction, the stop body accommodating the stop pin and the pressure pin displaceably relative to one another in an axial direction. That is to say, both the stop pin and the pressure pin can each be moved in an axial direction independently of one another and with respect to the stop body.

Additionally according to the invention it is provided that the arresting device has a stop body, which at one end has a stop pin and at its end facing a pressure pin, holding the stop body the stop pin interchangeably . By means of an optional change of the stop pin by a stop pin of the same type, for example, a wear repair can be carried out. By means of an optional exchange of the stop pin by another type of stop pin, the stop device can be adapted to different doors. The different types of stop pins can be distinguished, for example, in their dimensions or their lock latch guide surfaces.

The arresting device is therefore made up of several parts and comprises a stop body, a preferably interchangeable stop pin and a pressure pin. The arresting device preferably forms a closed module. The closed module itself of the arresting device can be constructed separately that is, independently of a door opener. It can be marketed as an independent module. The arresting device, unlike the solutions of the state of the art, does not require any constructive adaptation of an existing door opener and also makes it possible to ensure high operational safety.

The stopping device can be used flexibly. The stop device is inserted in a housing space of a door opener to retrofit the door openers. The opening space of the door opener is arranged in the door opener door opener. In this way, an existing door can be easily retrofitted with a stop device without having to make large constructional adaptations.

It is provided that the stop device can be mechanically connected to a door opener. It is inserted in a housing space in the lock release latch of the door opener and there it is held in shape drag. The Stop device is requested to its closing position by a lock latch. By engaging in the case of a door located in closed position a lock latch of a door lock in the accommodation space formed by a lock release latch and thereby cooperate with the stop pin of the arresting device so that the stop pin is requested by the lock bolt inside the door opener housing. The arresting device cooperates additionally with the blocking device or an element of the blocking device, for example a bar or an armature of the lock release in such a way that, after a remote-controlled switching of the lock-release latch to the released position, mechanically held in the released position until the lock release latch is pivoted and / or the lock latch is disengaged from the arresting device.

Remote controlled switching means in this case, for example, an electric or pneumatic opening pulse is sent to the door opener blocking device. This opening pulse switches the blocking device to the released position, so that the lock-release latch can be pivoted. In the case of conventional door openers the door must be opened while the opening pulse lasts. The stopping device is configured to maintain the door opener locking equipment also upon completion of the opening pulse in the released position. For this purpose, the arresting device cooperates with the locking device, in particular the arresting device transmits the force exerted through the lock latch to a locking lever of the locking device and requests it to the released position. The engagement of the locking lever is preferably carried out through the pressure bolt of the arresting device.

It is envisaged that the stop device with the pressure bolt and the stop body is inserted into the lock release housing or a housing space of the lock release latch. In the insertion the pressure bolt of the arresting device is placed directly adjacent to a locking lever. In particular, the pressure pin is in contact with a locking lever, preferably a bar that cooperates with the lock release latch. In this respect, a force exerted through the lock bolt to the stop pin is transmitted by the pressure bolt to the locking lever, so that the locking lever is urged in the direction of the released position.

An opening of the lock release is made when an opening pulse is sent to the blocking equipment and then the locking lever is activated. The locking lever then reaches the released position. After the opening pulse is switched off, the locking lever as a result of the stop device remains in the released position until the pressure bolt exerts the force transmitted by the lock bolt via the stop pin to the locking lever. After the door lock latch is pivoted or when the latch bolt is retracted by means of a latch, the force is exerted on the stop pin and thus on the locking lever. This can be moved back to the locked position. In the locked position the locking lever cooperates with the door lock latch through a stop and prevents the door lock latch from swinging.

According to the invention, it is provided that the arresting device can be inserted in such a way in the receiving space that the stop body is fixed in the door opener at least in the axial direction. For example, the stop body can be screwed or glued with the lock release latch or can be held in the form of a latch on the door release latch.

In order to be able to adapt the door opener to different doors, it is provided that the door opener latch has a transversely displaceable and removable screwing part. After the screw-in part has been placed on the lock release latch, the stop pin passes through an elongated hole in the screw-in part and extends in the direction of a lock latch. By means of the transversely movable screwing part, for example, the opener can be adapted to suit the existing joint of a door, the elongated hole allowing a transverse displacement of the screwing part.

In particular, it is provided that the stop device has a compression spring disposed between the stop pin and the pressure pin. The compression spring can be configured as a helical compression spring. It makes possible a compensation of length between pin of pressure and pin of stop and at the same time a transmission of strength. In particular, the compression spring is compressed when a lock latch engages the stop pin. This spring force is transmitted through the pressure bolt to the locking equipment, preferably a locking lever or bar of the locking equipment.

To ensure high operational safety in a configuration, it can be provided that the stop body has a guide sleeve, the internal contour of which is at least in sections complementary to the external contour of the stop pin in order to guide the pin stop in an axially displaceable manner. The guide sleeve supports the stop pin in front of lateral loads. That is, in the case of eccentric or lateral stressing of the stop pin, this force is absorbed by the guide sleeve and prevents jamming of the stop pin.

In one configuration, it can be provided that the stop pin is movably received via a detachable holding connection in the stop body. By means of an exchange of the stopping pin, it is easy to replace, for example, a worn stop pin.

In a configuration, different types of stop pins can also be provided, so that by means of the interchange of the stop pin or by means of selected selection of a type of stop pin, it is possible to adapt to the dimensions of a door opener. In particular the pin The detent can be configured in such a way that the stop pin at its free end has a lock latch support and at its opposite end an elastic retaining bead, with which the stop body can be inserted and can be inserted therein. Preferably, it can be provided that the resilient retaining heel engages behind one end of the guide sleeve for attaching the stop pin to the stop body.

In one configuration the stop pin can have a guide section extending between the retaining bead and the lock latch support, which can be guided in the guide sleeve in a positive engagement. The guide section preferably has a cylindrical shape.

Advantageously the arresting body can hold the stop pin securely against twisting. In particular, or when the arresting body has a slot in which a bead of the stop pin engages, or when the stop pin presents a slot in which a bead of the stop body engages. The groove may be arranged, for example, in the area of the guide sleeve or of the guide section.

Additionally in a configuration it can be provided that the stop pin has a rectangular or oval lock latch bearing surface. Through the locking latch support surface designed longitudinally in the event of a different joint play or in the case of a joint play that varies over time a lock latch can also be guided securely. A gap between the lock latch guide surface and a bolting part can be prevented in this way. A simple adjustability is produced by being able to join, in particular to be able to fit, the stop pin with the stop body in two positions rotated 180 ° to each other. By turning the 180 ° detent pin, the guiding area of the rectangular or oval lock latch bearing surface can be adjusted in this way.

In order to create a dirt-resistant configuration, it can be provided that the stop body and the stop pin and the pressure pin together form a construction space, in which a compression spring is accommodated. The construction space can be enclosed in a closed manner by the stop body and the stop pin and the pressure pin.

In order to hold the compression spring, it can be provided that the stop pin has a round recess in which the compression spring is received. Equally or alternatively it can be provided that the pressure bolt has a round recess, in which the compression spring is accommodated.

In a configuration it can be provided that the pressure bolt has a pressing surface for the support on a locking lever of the door lock blocking equipment. It can be provided that the pressure surface is formed rounded, in particular is configured as a pressure surface in the form of a hemisphere. By means of the rounded pressure surface of the pressure bolt it is ensured that a locking of the pressure bolt with the door opener mechanics is discarded to a greater extent. A door opener mechanism or a door opener blocking device has fabrication and surface tolerances conditioned by manufacturing. These can lead to the surface of the blocking device and / or the locking lever and / or adjacent components not being smooth, but in each case having small projections. When the stop device is actuated or when the lock release latch is pivoted, the stop device moves, which causes the pressure pin to slide along the surface of a lever of the locking device and / or components adjacent. By means of the rounded configuration of the pressure bolt, in particular in the area of its pressure surface, an engagement of the pressure bolt is prevented.

In order to make a simple repair possible, provision can be made for the pressure bolt to be interchangeably received in the stop body, preferably for the pressure bolt to be mounted in a displaceable manner via a detachable retaining connection in the stop body.

In order to enable a play-free housing and thus high operational safety, it can be provided that the stop body has a support section which is in contact, at least in sections, with an external contour of the pressure pin for guiding the pressure pin axially displaceable. In particular, a clamping of the pressure bolt in the arresting body can be carried out, provided that the pressure bolt has an elastic retaining flange which engages behind a recess provided in the internal wall of the arresting body arranged to join the stop pin with the stop body.

In an advantageous configuration, the remotely operable door opener can be provided with a retrofit set. The retrofit kit comprises at least two different stop pins with bearing surfaces of different dimensions and / or axial extension in each case, one of these stop pins being able to be inserted in the stop body and being able to be fitted with it to adapt the device of detention to a door. In this way, it is possible to retrofit already finished doors or doors already delivered with a door opener operable by remote control. By exchanging the arrest plug with a plug With other dimensions, a simple adaptation can be made to the circumstances and / or respective construction dimensions. By means of the bearing surfaces of different dimensions, which differ in their width and / or length, for example, an adaptation to different configurations and / or positions of a lock bolt and / or of a bolting part can be carried out. By means of the provision of stop pins with different axial extension, for example, an adaptation can be made to different depths of immersion of lock latches. In the case of a shorter immersion depth of a lock latch, for example, a stop pin with a larger axial extension can be used.

In particular, it can be provided that the door opener has a housing that is intended to be mounted on a door with a door frame and a door leaf movably received therein. A lock is also provided on the door which has a lock latch which is preferably spring-loaded and which cooperates at least in the closed position of the door with the lock-release latch. A door lock latch which cooperates with the lock latch and is movably received in the door lock housing is housed, as well as a remote-controllable locking device. The blocking device has an interposed bar which is configured as a lever of an arm or of several arms. The bar cooperates with the lock release latch so that the lock release latch can be switched to a locked position and a released position. In particular, the bar is connected between an actuator that can be operated by remote control and the lock release latch.

In particular, it is provided that the lock-release latch has a receiving space open towards the blocking device in which the arresting device is housed. For example, the arresting device can be detachably received in the receiving space, preferably inserted in a positive fit.

In a configuration it can be provided that the stop body is designed in the form of a cylinder and has at one end a protruding flange, which can be inserted in a form-fitting into a notch arranged in the door-opening latch and preferably ends aligned with the surface of the door. latch.

A simple assembly occurs when the diameter of the elongated hole has a smaller internal diameter than the stop body or the flange of the stop body.

In the figures, examples of embodiment of the invention are shown and explained in the following description of figures in more detail. In this regard they show:

Figure 3a-3c: a schematic representation of the detention device

Figure 3d-3e: a schematic representation of the arresting device with anti-twist lock Figure 4, 5, 6: a sectioned representation in the area of the lock latch

Figure 7: a sectioned representation in the area of the lock latch without lock bolt. In figure 1 a building door 9 is shown. The building door 9 presents a door frame arranged in a wall of a building, as well as a leaf member rotatably housed in the door frame through hinge pins 92a, 92b. The door 9 is secured by a security device. The safety device comprises a lock 8, a door opener 2 and a stop device 1 incorporated in a housing space 24 of the door opener 2.

In the leaf 92, the lock 8 is inserted as a recessed lock 8 in a strike. The recessed lock 8 has a spring loaded latch bolt 8. This can be retracted through a latch 82 or through a locking cylinder that can be actuated by a key towards the lock housing to pass through the door 9.

The door opener 2 is arranged on the frame side facing the lock 2. The door opener 2 has a door opener housing 21 in which a pivoting latch 22. The opener 2 is configured as an electric open circuit door opener. That is, the door opener in a power supply releases the door opener latch 22 and blocks it in the currentless state. A stopping device 1 is housed in the area of the door lock latch 22, which can be seen from FIGS. 2a to 2c. In Figure 1 the stop device for reasons of simplification is not drawn.

Figure 1 shows the door in closed position. In the closed position the lock latch 81 engages in a lock latch housing space, which is formed by the latch bolt latch 22. When the latch latch 22 is locked, ie, with the latch 2 in the locked position, the latch The door opener 22 is fixed and can not be pivoted. In other words, the leaf 92 is secured against an opening in the closed position through the lock latch 81 which engages in the latch bolt 22. Only after the latch bolt 81 retracts and / or after the latch bolt activates. door opener 22 the door 92 can be opened to pass through the door 9.

The opening of the door 9 is carried out by means of an electric opening pulse. This opening pulse changes the door lock latch 22 to the released position, so that the door lock latch 22 can be pivoted. In conventional door openers the door 9 must be opened while the opening pulse lasts. Otherwise the lock release latch locks automatically again.

The stop device 1 is configured to maintain a locking device 3 of the lock release 2 which locks the lock release latch 22 also after the opening pulse has ended in the released position. Only after opening the door by pivoting the lock release latch 22 or by retracting the lock latch 81 is the blocking device 3 effective.

In figures 2a to 2c the lock release 2 is shown enlarged. The lock release 2 has a lock release housing 21 with a removable lid 21d. In figures 2a and 2b the lock-release door 21d is shown. In figure 2c the cover is removed to represent in more detail the mechanics of the lock release. The lock release latch configured as a pivoting latch 22 is pivotally received in the lock release housing 22. The latch bolt 22 is formed in two parts. It has a bolt base and a bolting part 23 that can be screwed into it. The bolting part 23 is designed in an L-shape and has a locking man which cooperates with a lock bolt 81 to secure the lock bolt in the closed position. The screw part 22 is screwed through two screws 232a, 232b into the lock latch part 22. The threaded holes are configured as longitudinal holes. Both the lock latch base portion 22 and the screw portion 23 have a grooved contact surface. The screwing part 23 can be displaced transversely to the door opener 2 and can be fixed through the screws 232a, 232b to a desired transverse position. For this reason, the door opener 2 can be adapted, for example, to different play dimensions of a door seal.

The lock release latch 22 has a receiving space 24 into which the stop device 1 can be inserted. The stop device 1 is formed of several parts. It comprises a stop body 11, a stop pin 12 housed therein and a pressure pin 13 fixed in the stop body 11. The stop device is shown in more detail in figures 3a to 3c. The stop body 11 as shown in FIGS. 2 a and 2 b, with the pressure pin 13 at the head, is inserted into the receiving space 24 of the lock release latch. After insertion of the stop device into the housing space of the lock release latch 22, the screwing piece 23 is screwed with the lock release latch 22. The screwing piece 23 fixes the stop body 11 on the lock release latch 22.

Figure 2c shows the lock release 2 from the rear side, ie from the opposite side of the lock release latch 22. The lock release housing 21 has at one of its ends an electrical connection block 25 by means of which the electric lock release 2 can connect electrically The lock-release mechanism comprises a blocking device 3, by means of which the pivoting latch 22 can be changed by remote-controllable electricity between a released position, in which the latch bolt 22 can be freely pivoted, and a locked position, wherein the pivoting of the lock release latch 22 is blocked. The locking device 3 comprises a locking lever 31 rotatably mounted around a pivot axis 31a, which serves as a rod. Additionally, the blocking device 3 comprises an armature 32 housed around a rotation axis 32a. The armature 32 can be driven by an electromagnet 33 and cooperates with it to fix the armature 31 in the locked position. The locked position is shown in FIG. 2c. The armature 32 has a projection and fits behind the end of the bar 31 to fix it in the locked position. In the locked position the bar 31 is in contact with the lock release latch 22.

The locking lever 31 has a stop 34 on which a protruding edge or bead of the door-release latch 22 rests and prevents the door-opening latch 22 from pivoting about its pivot axis running in the longitudinal direction of the door-opening housing. two.

The bar 31 has a bar spring 31f as a return spring which is designed as a helical compression spring and urges the bar 31 towards the locked position. Also the armature 32 is urged by a return spring 32f to its locked position. This means that in the state without current both the bar 31 and the armature 32 can be spring-loaded to the locked position. The lock release 2 is configured as an open circuit door opener, that is, it is locked in the no-current state.

The stopping device 1 is shown in more detail in figures 3a to 3c. Figure 3a shows an exploded representation of the stopping device 1. The stopping device 1 has a stop body 11. At one end of the stopping body 11, the stopping pin 12 is housed and at the other end the locking bolt is mounted. pressure 13. The stop pin 12 the pressure pin 13 are arranged in each case in the same axial direction, i.e. coaxial and displaced relative to one another in the axial direction and independently movably housed. A helical compression spring 14 is provided between the stop pin 12 and the pressure pin 13, which requires both the pressure pin 13 and the stop pin 12.

The detent pin 12 has at its free end a lock latch bearing surface 121a. At the opposite end, the detent pin 12 has a detent heel 122. The retaining heel 122 configured as a surrounding retention heel. A guide section 123 of the detent pin extends between the detent bead 122 and the lock latch support 121a. The guide section 123 cooperates with a guide sleeve 111 of the stop body for guiding the stop pin 12.

The pressure pin 13 has at its free end a pressure surface 131 in the form of a hemisphere. The pressure surface 131 acts on a locking lever 31 of the blocking device 3. At its front end the pressure bolt 13 has a retaining cover 132 by means of which the pressure pin 13 engages in the stop body eleven.

In Figure 3b and 3c, the stopping device 1 is shown in each case in the assembled state. Figure 3b shows a variant of the stop device with a first stop pin 12, which has a wider latch bolt support 121b. The exemplary embodiment shown in FIG. 3c, except the stop pin 12, corresponds to the embodiment shown in FIG. 3b. In FIG. 3c, a second detent pin 12 is used, which has a smaller lock latch support surface 121a.

By means of a selected selection of a suitable stop pin 12, the stop device 1 can be adapted to the respective local circumstances.

The illustrated embodiment of the stopping device 1 in figures 3d and 3e corresponds to a greater extent to the embodiment presented in figures 3a and 3b. In contrast to the embodiment shown in FIGS. 3a and 3b, in this case, the stop device 1 has an anti-twist lock for the stop pin 12. The stop pin 12 has an oval lock pin guide surface 121b lock latch support 121b. In the guide section 123 of the detent pin 12, a protruding bead 124 is formed. The detent body 11 has in the region its guide sleeve 111 two facing grooves 114. In the representations of FIGS. perspective only one of these slots 114 is visible.

The stop pin is joined to the stop body so that the heel 124 or is engaged in the anterior slot 114 or in the rear slot 114. In this respect the lock latch guide surface 121b is rotated 180 ° and indicates or according to the figure 3d upwards, or according to the representation in figure 3e downwards. By means of this adjustability of the lock latch guide surface 121b, it is possible, especially in combination with a displaceable screw part 23 shown as in FIG. 5, to have a greater displacement area of the screwing piece 23 without entering the Screw piece 23 and lock latch guide 121b form a large gap. Therefore, the risk of fitting a lock latch is prevented.

From the sectioned representation of the door opener 2 shown in FIGS. 4, 5, 6 and 7, the blocking device 3 housed in the door opener housing 21 is visible. The blocking device 3 presents the armature 32 requested by an electromagnet 33, where the armature 32 is not visible in the sectioned representation. Additionally, the blocking device 3 comprises the bar 31, which can be locked by the armature 32. Both the armature 32 and the bar 31 are rotatably mounted in the lock-release housing 21 in each case on axes 31a or 32a arranged in parallel each. The electromagnet 33 has an electric coil that is housed in a coil housing 331 and is fixed in a stationary manner in the door opener housing 21.

Figure 4 shows the lock release 2 in the locked position. The locking lever 31 is in a position close to the lock release latch 22. The locking lever abuts the lock release latch 22 and locks it. A lock latch 81 engages in the locked latch bolt 22 or in the bolt 23 and requests the latch pin 12. The latch pin 12 is pre-tensioned by the intermeshing spring 14 against the pressure bolt 13. The pressure pin 13 with its pressurized surface 131 is in contact with the locking lever 31 and, by means of the locking lever 31, penetrates into the interior of the stop body 11. The spring 14 is pre-stressed to its maximum in its locked position shown in FIG. Figure 4

The pressure pin 13 and the stop pin 12 are configured so that they can be inserted into each other in the manner of a telescope. In the configuration shown in FIG. 4, the pressure pin 13 has an internal opening in which the stop pin 12 can be inserted. The pressure pin 13 has an internal opening with a greater internal diameter at its end housed inside the stop body. or equal to the external diameter of the detent pin 12 or the outer diameter of the retaining bead 122. The detent pin 12 engages in the locked position with its end opposite the lock latch support 121a in the internal opening of the locking bolt. pressure 13. The stop pin 12 is therefore movably mounted on both the stop body 11 and the pressure pin 13. Therefore, in a compact construction mode of the stop device 1, an effective sliding length is realized. of the stop pin 12 and the pressure pin 13. In an alternative configuration also the stop pin 12 p It can present an internal opening into which a section of the pressure pin 13 can be inserted.

To release the electric lock release 2, the electric coil 33 is supplied with current. The armature 32 is then switched on and releases the locking lever 31. The pressure bolt 13, which is prestressed by the spring 14, pushes the locking lever 31 to the released position shown in FIG. Lock 31 is disengaged from the lock release latch 22 and the lock release latch 22 can be freely pivoted. Even if now the power supply of the coil 33 ends the locking lever 31 remains in a released position, since the pressure pin 13 requests the locking lever 31 additionally towards the released position. Only after the opening of the door or the retraction of the lock latch 81 the compression spring 14 becomes loose and the pressure pin 13 can move from the return spring 31f of the locking lever 31 towards the interior of the stop body 11. After the retraction of the lock latch 81, the locking lever 31 is therefore moved by its return spring 31f back to the locked position to lock the door lock latch 22.

A second possibility for locking the door lock latch 22 after the unlocking has been carried out is to pivot the door lock latch 22 by opening the door, as shown in FIG. 7. This has as a consequence that the latch bolt 22 pressure 13 also comes to be disengaged from the locking lever 31 and this, as a consequence of its recoil spring 31f, is brought to the locked position to fix the lock release latch 22.

Figure 5 shows a cut through the lock release 2 with stop device 1. This requests the lock lever 31 released to the released position and prevents it from blocking the bolt 22. This happens in the following manner. The lock latch 81 engages in the housing space of the bolted latch part 23. The flat side of the latch bolt 81 is in contact with the locking shoulder of the bolting part 23 and is held by it. The tip of the lock latch 81 also activates the stop pin 12 of the stop device 1. The stop pin 12 in turn acts on the compression spring 14 and transmits the strength of the lock bolt through this compression spring 14 to the pressure bolt 13. The pressure bolt 13 with its pressing surface 131 is in direct contact with the locking lever 31 and requests it to the released position. By means of the force transmitted to the locking lever 31 of the pressure bolt 13, the return spring 31f can not move the locking lever 31 to the locked position.

The lock latch 22 is shown in Fig. 5 in the closed position, that is, with the door closed. By opening the door, the lock release latch 22 pivots about its axis of rotation. In FIG. 7, the same lock release 2 with latch release 22 pivoted outwards is shown. In contrast to the representation in FIG. 5 in FIG. 7, the lock latch 81 is now disengaged from the lock release latch 22 and the stop pin 12 has been discharged. That is to say, the stop pin 12 thus protrudes from the base of the lock release latch 22. Therefore, the force exerted on the pressure pin 13 is reduced, so that the return spring 31f can move the bar 31 to the position blocked up. In addition, the pressure pin 13, as a result of the pivoting movement of the lock release latch 22, disengages from the bar 31 and releases it. The pressure pin 13 in the pivoting of the lock release latch 22 slides on the bobbin case 331 of the coil33. The locking lever 31 in the pivoted position shown in FIG. 7 as a result of the return spring 31f can be moved back to the locked position in order to lock the door lock latch 22 in the locked position as soon as it is swiveled backward.

Figure 6 shows a sectioned representation of the door opener 2 corresponding to figures 4 and 5. The only difference with the embodiment shown in figure 4 and 5 in this case again in the stop device 1 is inserted a stop pin with a wider lock latch support surface 121b.

In general, in the described stopping devices 1 the opening pulse, which can be activated by a remote control, is stored or extended, so that after opening or deactivating the opening pulse, which can be controlled by remote control, an opening state of the door opener 2 is mechanically maintained and delayed door transit is possible.
