EP2963210B1 - Passive leaf lock - Google Patents

Description

The invention relates to a passive wing lock, which has the features of the preamble of claim 1.

From the DE 10 2006 038 610 B4 such a passive wing lock is known. The electric door opening device is included as an independent unit in the lock case of the passive wing lock. As usual, the door opener assembly has a door opener housing to be mounted in the door frame, in which all components of the door opener are arranged. The door opener assembly is in the DE 10 2006 038 610 B4 used in the lock housing of a passive wing lock, in a separate space that is designed as a recess in the lock mechanism. In order to be able to mechanically unlock the basically electrically switchable door opener in the closed position of the door, in the DE 10 2006 038 610 B4 a mechanical unlocking device is provided, which with the locking bar connection device is coupled in the lock housing. The mechanical unlocker engages in the door opener housing in order to mechanically unlock the electrical locking device of the door opener. Here, the mechanical unlocker engages the armature of the electromagnet of the electrical locking device.

A disadvantage of this prior art is that the door opener unit in the passive wing lock requires a relatively large amount of installation space and designs with a lock housing with small dimensions cannot be implemented.

The invention is therefore based on the object of creating a passive wing lock of the type mentioned at the outset, which is of compact construction and also allows designs of lock cases with small dimensions.

The invention solves this problem with the subject matter of claim 1. This solution provides the AND alternatives a) and b).

Alternative a) provides that at least the following door opener components are arranged in the lock housing: the door opener latch, the electrical actuator, the locking member on the output side and, if present, the door opener gear interposed between the door opener latch and the locking member on the output side. In this case, no separate door opener housing should be provided in or on which all these door opener components are mounted. This means that no separate common door opener housing is required for the door opener components, in which all door opener components are accommodated, as in conventional door openers. The door opener components can be used individually or in groups in appropriate open spaces in the Lock housing, preferably be arranged in recesses in the lock gear. Versions are possible in which one or more of the door opener components are accommodated in separate housings and these housings are arranged in the lock housing. In contrast to the prior art, however, not all door release components are stored together in one door release housing.

The alternative b) provides for the distributed arrangement of the door opener components in the lock housing in the sense of the same inventive concept. It provides that at least the following door opener components: the door opener latch, the electrical actuator, the locking member on the output side and, if present, the door opener gear interposed between the door opener latch and the locking member on the output side are distributed in the lock housing in such a way that one between at least two of the door opener components Component of the lock mechanism or at least part of a component of the lock mechanism engages.

Both alternatives a) and b) are used together in order to obtain an optimal arrangement of the door release components relative to the components of the lock mechanism in the lock housing.

In this sense, versions are particularly advantageous which provide that the door opener latch is designed as a swivel latch and has a swivel bearing which is in the lock housing directly, that is to say without the interposition of one of the swivel bearing and / or the door opener latch and / or the electric locking device and / or other door opener components receiving another housing is arranged.

An optimization of the arrangement can be obtained with designs which provide that the door opener latch is designed as a swivel latch and has a central swivel axis for the left-right use of the door opener latch.

Favorable component arrangements are also possible in designs which provide that the locking member is designed as a locking lever and has a pivot bearing which is located directly in the lock housing, ie. H. is arranged without the interposition of a further housing receiving the pivot bearing and / or the locking lever and / or the electrical locking device and / or further door opener components.

Advantageous embodiments provide that a transmission slide or a transmission pivot lever is connected between the locking member and the door opener latch, which is designed as the door opener gear or as part of the door opener gear. In a preferred development, it can be provided that the transmission slide or the transmission pivot lever has a sliding bearing or a pivot bearing which is located directly in the lock housing, ie. H. is arranged without interposing a further housing receiving the transmission slide or the transmission lever and / or the electrical locking device and / or the door opener latch and / or further door opener components.

According to the invention, it is provided that the lock mechanism has a lifting device which, in the closed position of the door, interacts with a lock latch or a bolt of an assigned active leaf lock. It is essential that the lifting device or at least part of the lifting device is arranged between two door opener components.

As an alternative or in addition, it can be provided that the two door opener components are designed on the one hand as the door opener latch and on the other hand as the electrical actuator and / or the locking member on the output side and / or the door opener gear.

The Figures 1a to 4 show embodiments of a passive wing lock according to the invention with advantageous configurations and features that in the combination of features shown can be used. In alternative configurations, a combination of individual or a part of features shown in the figures with additional features not explicitly shown in the figures is also provided. Embodiments are also provided which do not have all of the features shown in the figures in their entirety, but only contain a selection of the features shown, without leaving the scope of the invention, which is defined by the claims.

That in the Figures 1a to 4 The passive wing lock 1 shown has a lock housing 2, in which a lock mechanism and a door opener device 5 integrated in the lock mechanism are arranged. The lock mechanism comprises a lock gear with a slide 4 which can be actuated via a nut 3. The lock mechanism also has a bolt lifting device 6 for a bolt of an associated active leaf lock. Furthermore, the lock mechanism has a connecting device for an upper locking bar 7 and a connecting device for a lower locking bar 8.

A significant difference from conventional passive wing locks that are equipped with an electric door opener in the exemplary embodiment shown is that the components of the door opener device are stored independently in the lock housing 2. There is no separate door opener housing that accommodates all door opener components. In the case shown, the components of the door opener device are interleaved with the components of the lock mechanism in the lock housing. Components of the lock mechanism intervene between components of the door opening device.

The door opener device 5 has a pivotally mounted door opener latch 51 and an electrical locking device 52 as the door opener components. The electrical locking device 52 interacts with the door opener latch 51 via intermediate gear elements. The electrical locking device comprises an electrical coil 52s and an armature 52a, which cooperates with the coil 52s as an output-side blocking element. The armature 52a is in the illustrated case in the manner of a flat single-armed lever pivotably mounted about a pivot axis 52aa and is arranged on the top of the coil 52s. A transmission slide 53 is arranged between the armature 52a and the door opener latch 51. It interacts directly with the door opener latch 51 on one side and directly with the armature 52a on its other side. For this purpose, the transfer slide 53 has on its side facing the armature 52a a stop edge 53k which interacts directly with the armature 52a.

The door opener components are arranged in the lock housing 2 such that the door opener latch 51 is arranged adjacent to the faceplate and the pivot axis 51aa of the door opener latch 51 is aligned parallel to the faceplate. The electrical locking device 52 is arranged near the face-side rear side of the lock housing 2. The transfer slide 53 is arranged adjacent to the door opener latch 51. Its direction of movement extends between the faceplate and the faceplate rear side of the lock housing 2, d. H. in the transverse direction of the lock housing 2 and thereby transverse to the direction of displacement of the slide 4.

The door opener latch 51 is designed as a swivel latch. It has a pivotably mounted door opener fall body 51k, on which a screw-on piece 51a is screwed. The works via the screw-on piece Door opener latch 51 together with a lock latch, not shown, of an assigned active wing lock.

In the lock housing 2, an unlocking slide 54 is displaceably mounted parallel to the electrical locking device 52, i. H. the unlocking slide 54 is displaceable parallel to the coil 52s and to the armature 52a. The unlocking slide 54 forms part of the lock mechanism. It forms a mechanical unlocker in order to actuate the armature 52a to mechanically release the electric door opener. For this purpose, the unlocking slide 54 has an actuating head 54b on the side facing the armature 52. The unlocking slide 54 is motionally coupled to the slide 4 of the lock gear. In the illustrated case, the unlocking slide 54 is designed as a section of the slide 4 and / or at least as a part that is fixed in terms of movement with the slide.

The door opening device 5 can be switched into a blocking position and into a release position. In the locked position, the door opener latch 51 is locked and the locking latch of the active-leaf lock engaging in the closed position of the door is retightened in order to lock the active leaf in the closed position. In the release position, the door release latch is unlocked so that the lock latch is released when the active leaf is pushed open.

The switching between the blocking position and the fig order can be carried out by electrical control, in that the electrical blocking device is switched electrically. This means that the electric door release device is unlocked by electrically switching the electric locking device 52. Alternatively, the electrical can be activated Door release device possible by mechanical unlocking. This is done by mechanically actuating the unlocking slide 54, which in the exemplary embodiment of FIG Figures 1 to 4 acts on the armature 52a via its actuating head 54b.

In the embodiment of the Figures 1 to 4 in the locked position of the door opener latch, the armature 52a is in its position pivoted away from the coil 52s, as shown in FIG Fig. 3s is shown. The transfer slide 53 arranged between the armature 52a and the door opener latch 51 abuts with its stop edge 53k on the armature 52a pivoted upwards. This is in Fig. 4s shown. The transfer slide 53 forms a stop for the door opener latch 51 with its cuff-side edge. The door opener latch 51 is locked in this position against swiveling in the release position. During mechanical unlocking, the armature 52a is pivoted into its release position resting on the spool 52s by moving the unlocking slide 54. The position is in the Figures 3 and 4 shown.

The armature 52a is thus outside the displacement path of the transmission slide 53, so that the door opener latch 51 is activated for pivoting. If in this position the door opener latch 51 is acted upon by the lock latch in the opening direction, it pivots and releases the lock latch. Swiveling the door opener latch is possible because the transfer slide 53 is not blocked by the armature 52a of the electrical locking device. When the door opener latch 51 is pivoted, the transmission slide 53 dodges.

The electrical unlocking takes place by changing the energization of the electrical locking device 52. Starting from the locking position, as shown in the Figures 3s and 4s is shown, the armature 52a is pivoted into its position on the coil 52s by changing the current supply. The armature 52a thus comes out of the movement path of the transmission slide 53. If the door opener latch 51 is now acted upon by the lock latch to open the door, the door opener latch 51 pivots, since the transmission slide 53 is now no longer blocked by the armature 52a and can escape. This release position is the same as for the mechanical release and in the Figures 3 and 4 shown.

In the in the Figures 1 to 4 In the embodiment shown, it is provided that, as in the conventional known systems, the mechanical unlocker 54 acts on the output-side locking element of the electrical locking device, specifically on the armature 52a, which interacts with the coil 52s of the electromagnet. In the sense of the present invention, this embodiment would have to be modified according to the invention, for example in such a way that the mechanical unlocker 54 interacts with the transmission slide 53 of the door opener gear, which acts as a change. In the mechanical unlocking position, the mechanical unlocker 54 will then move the transfer slide 53 out of the engaged position of the door opener latch 51, for. B. by moving the transmission slide 53 parallel to the faceplate until it comes out of the operative position of the door opener latch 51. This then has the consequence that, in the mechanical unlocking position, the door opener latch 51 is disengaged from the transmission slide 53 and thus unlocked. In this embodiment, the transfer slide 53 can be moved in the same sliding bearing in which the transfer slide 53 is slidably mounted even when it cooperates with the armature 52a and the door opener latch 51. Alternatively, a modification in which the Transfer slide 53 a separate warehouse, for. B. has a second sliding bearing or a pivot bearing, in which the transmission slide 53 is displaced when actuated by the mechanical unlocker 54. It can also be provided that the mechanical unlocking device 54 acts on this additional bearing.

Further modifications compared to that in the Figures 1 to 4 shown embodiment are possible in the sense of the invention that z. B. the mechanical unlocker 54 cooperates with the door opener latch 51 and the door opener latch 51 is shifted for mechanical unlocking. This shift can take place in the pivot bearing of the door opener latch 51, in which the door opener latch 51 can also be displaced when it interacts with the lock latch and the transmission slide 53. Alternatively, the door opener latch 51 can also be a separate bearing, e.g. B. have a sliding bearing, in which the door opener latch 51 is displaced in cooperation with the mechanical unlocker 54 for mechanical unlocking. Alternatively, the door opener latch 51 can have a separate, movably mounted section which interacts with the mechanical unlocker 54 for mechanical unlocking and is displaced relative to the rest of the door opener latch 51.

In the in the Figures 5 to 12 Passive wing lock shown is a specifically executed modification of the passive wing lock Figures 1 to 4 . The lock mechanism of the passive wing lock is the same as for the lock in the Figures 1 to 4 . Only the door opener device 5 differs in structure from the door opener device in the passive wing lock in Figures 1 to 4 . The door opener has the execution of the Figures 5 to 12 the same components, namely a door opener latch 51, an electrical locking device 52 with coil 52s and armature 52a and a transmission slide 53, as well as an unlocking slide 54 which can be actuated via the lock nut 3. In addition, however, an intermediate member 55 is also provided, which is connected between the transmission slide 53 and the armature 52a and can be actuated by the unlocking slide 54. This means that in this case the transfer slide 53 does not interact directly with the armature 52a, but only indirectly via the intermediate link 55. In this case, the unlocking slide 54 only interacts directly with the intermediate link 55. The intermediate link has an elongated hole 55o, in which a driver head 4z of the unlocking slide 54 engages. The elongated hole 55o is aligned transversely to the faceplate and thus along the sliding direction of the transfer slide 53.

The door release device can be switched in the locked position and the release position. The locked position is in the Figures 7 and 8 shown. In this position, the armature 52a is switched in its blocking position pivoted away from the spool 52s, and the intermediate member 55 is arranged between the transmission slide 53 and the armature 52a such that the intermediate member 55, with its side facing the armature 52a, on a locking edge formed on the armature 52a 52ak is in abutment and its side facing the transfer slide 53 abuts against a stop edge 53k formed on the transfer slide 53. In this position, the transfer slide 53 is blocked against displacement in a direction away from the faceplate via the intermediate member 55. The intermediate member 55 is in turn blocked by the locking edge 52ak formed on the armature 52a in this sliding direction via the armature. The door opener latch 51 is in this position on the face plate of the transmission slide 53 and is in their Figures 7 and 8 Lock position shown locked against pivoting in the release direction.

In the Figures 9 and 10 the door opener device is shown in its release position, namely in its first release position, which is done by electrical switching of the electrical locking device. Due to the electrical release circuit of the locking device 52, the armature 52a is in its Figures 7 and 8 shown upward pivoted locking position pivoted down to the coil 52s. It lies parallel to the lock case level. As in Figure 10 can be seen best in this position, the intermediate member 55 is out of contact with the locking edge 52ak of the armature 52a. This position in Figure 10 is reached based on the locked position in Figure 8 by pivoting the armature 52a out of the stop position with the blocking edge 52ak into its pivoting position resting on the spool 52s. The intermediate member 55 is then in a direction away from the faceplate in Figure 8 displaceable by the action of the transfer slide 53. The sliding movement of the intermediate member 55 takes place by the action of the transfer slide 53 when the door opener latch 51 is out of its in Figure 8 shown locking position is pivoted into its release position by the lock latch when opening the active wing. Figure 10 shows this position after the release pivoting of the door opener latch 51.

In the Figures 11 and 12 the release position of the door opener device after mechanical unlocking via the unlocking slide 54 is shown. This is different from that in the Figures 9 and 10 electrical release position shown referred to as the second release position. In this in the Figures 11 and 12 release position shown is the intermediate member 55 from the in the Figures 7 and 8 illustrated locking position out in its mechanical release position shifted. The direction of movement for this displacement of the intermediate member 55 is a direction of movement parallel to the faceplate and thus transversely to the direction of displacement of the transfer slide 53. The displacement of the intermediate member 55 takes place up to that in FIGS Figures 11 and 12 Position shown, that is, so far that the intermediate member 55 is outside the locking edge 52ak formed on the armature 52a. This means that the transmission slide 53 is no longer prevented by the intermediate member 55 and also no longer indirectly by the armature 52a from being displaced away from the faceplate in the release direction and therefore the door opener latch 51 from it into the Figures 7 and 8 shown locking position in the release position of Figures 11 and 12 can be pivoted by shifting the transfer slide 53. The intermediate member 55 is entrained by the transfer slide 53 and freely displaced in the plane above the armature 52a. The armature 52a does not hinder this displacement movement of the intermediate member, since the intermediate member is out of the operative connection of the armature. In the in the Figures 11 and 12 The mechanical release position shown is irrelevant to the switching position of the armature, ie the armature can be brought electrically into the locked position and release position in this mechanical release position without the mechanical release position being influenced thereby.

In contrast to the mechanical release order in the Figures 9 and 10 electrical release position shown the position of the armature essential. In this electrical release position, the armature must be arranged in its electrically determined release position, that is, pivoted downward towards the coil 52s in the case shown. As soon as the electrical blocking device is switched electrically into the blocking position, the armature 52a is shifted into its blocking position in the case shown in a position pivoted away from the spool 52s as shown in FIGS Figures 7 and 8 is shown.

In the embodiment of the Figures 5 to 12 the mechanical unlocker 54 interacts with the transmission slide 53 interposed between the door opener latch 51 and the output-side armature 52a of the electrical locking device 52 via the intermediate member 55. The mechanical unlocker 54 acts to mechanically release the electric door opener on the intermediate member 55 and not on the armature 52a.

In both exemplary embodiments, which are shown in the figures, the features a) and b) of main claim 1 are realized. The door opener components are arranged directly in the lock housing, without a separate door opener housing being provided, which accommodates the door opener components: door opener latch, electrical actuator, output-side locking member and door opener gear in its entirety or only a few of them. Furthermore, the mentioned door opener components are distributed in the lock housing in such a way that components of the lock mechanism engage between at least some of the door opener components.

In the embodiment of the Figures 5 to 12 The lock mechanism comprises a slide 54 which can be actuated by the nut 3 in order to actuate the bolt lifting device 6 and the connecting devices for the upper locking rod 7 and the lower locking rods 8. Between the transmission slide 53 as part of the door opener gear and the armature 52a of the electrical locking device 52, the slide 54 engages as a component of the lock mechanism via the intermediate member 55 and thus acts as a mechanical unlocking device 54.

In the embodiment of the Figures 13 to 14 is a passive wing lock, which is largely constructed the same as that of the Figures 5 to 12 . The passive wing lock is also equipped with a door opener device 5. The door opener device 5 points in accordance with the door opener device in FIGS Figures 5 to 12 a pivotable door opener latch 51 and an electrical locking device 52 with a pivotably mounted armature 52a. A transmission slide 53 is also connected between the door opener latch 51 and the armature 52a. Unlike the Figures 5 to 12 However, no intermediate member 55 is connected between the transmission slide 53 and the armature 52a, which is actuated via the mechanical unlocking device 54. Please refer to 13a . The mechanical unlocker 54 acts on the transmission slide 53 in order to displace it relative to the door opener latch 51. The locked position of the door opener latch 51 is in the Figures 13a and b shown. The transmission slide 53 is in contact with the door opener latch 51. When the electrical locking device 52 is switched to the locked position, it is like Fig. 13b shows the armature 52a pivoted away from the spool 52s and blocks the transfer slide 53 to perform a compensatory movement in the transverse direction. Because of this blocking of the transmission slide 53, the door opener latch 51, which is in abutment with it, is blocked in this position against a pivoting movement. This is in the Figures 13a and b shown.

Reference is made to the Figures 13c and d. When the electrical locking device 52 is electrically unlocked, the armature 52a is moved out of the path of movement of the transfer slide 53. The transfer slide 53 can now perform an evasive movement over the now retracted armature 52a when the door opener latch 51 is closed the lock latch is loaded. The door opener latch 51 is thus unlocked in this position. This position shows the Figure 13d .

The mechanical activation of the door opener latch 51 is in the Figures 14a shown to d. The transmission slide 53 is shifted by means of the unlocking slide 54, specifically into a position outside the stop position with the door opener latch 51 Figures 14a and b show the shifted position of the transmission member 53 compared to the starting position shown in Figure 13a is shown.

In this position, the transmission slide 53 engages in a freewheel recess 51f of the door opener latch 51 in such a way that the door opener latch 51 can pivot freely from the transmission slide 53 when the lock latch acts on the door opener latch 51 to open the door. The door opener latch pivots into the release position, which in the Figures 14c and d is shown.

In the same way as in the exemplary embodiments described above, the mechanical unlocking device 54 can be designed as a section of the slide 4 of the lock gear. In modified versions, the mechanical unlocker can also be designed as a separate part, preferably as a part that cooperates with the slide 4 in the gearbox. In modified embodiments, the mechanical unlocking device 54 can also be used as a non-slider, e.g. B. be designed as a lever or as another gear element. Furthermore, the mechanical unlocker 54 does not have to interact with a gear element of the lock gear. The mechanical unlocking device 54 can be designed as a separate component independently of the lock gear. The actuation of the mechanical unlocker 54 takes place in the illustrated embodiments via the actuating device of the lock mechanism, preferably the nut 3. However, versions are also possible in which a separate actuating device is provided for actuating the mechanical unlocking device 54.

In principle, the actuating device of the mechanical unlocking device 54 is preferably designed such that it can be actuated from the inside of the door in which the lock is mounted. In any case, this applies to applications of the double-leaf door in escape and rescue routes.
