A driving bolt (120) of the door leaf stopping means may engage a door gap limiter mounted on the fixed frame. The main lock (102) and the door leaf stopping means (104) are coupled to each other (140, 112, 114, 198) so that the driving bolt (120) may be disengaged from the door gap limiter by the main lock (102) only when the latch (178) of the main lock (102) is actuated by a closing element.

Description

The present invention relates to a locking device for a door or the like with a fixed frame and a wing, comprising a main lock on the wing with a by means of a Locking element, in particular key, via a bolt actuating device actuatable latch and one both by means of the closing element and by means of a door handle or the like. Can be actuated via a latch actuating device Case for engaging in a fixed frame side striking plate as well comprising a wing catch device separate from the main lock on the wing with a driving pin, which in one Casing of the wing trap with the help of a drive pin actuator between a release position and a driving position is movably mounted and at closed wing disengaged in its release position with an engaging portion attached to the fixed frame Gap opening limiter and in its driving position in Engagement with the engagement portion is for driving the gap opening limiter when opening the wing until it is reached a maximum determined by the gap opening limiter possible gap opening position of the wing, the main lock and the wing catcher coupled together in such a way are that the driving bolt from the main lock by means of of the closing element from the driving position into the release position is feasible.

Such a locking device is for example from DE 35 03 466 C2 known. It is a locking device for a door where the main lock acts as an espagnolette lock with one with the bolt actuation device coupled drive rod is formed. The connecting rod serves on the one hand for mechanical coupling of the main lock at least one additional lock separate from the main lock with one additional bolt each. By coupling the main lock with the at least one additional lock by means of Drive rod is achieved in that the additional bolt (s) Actuation of the lock of the main lock from the main lock can also be operated using a key. When extending the Bolt of the main lock is also the additional bolt of the at least one additional lock (with a corresponding shift the drive rod in one direction) and when retracting the latch of the main lock will be accordingly the additional bolt of the at least one additional lock (under Displacement of the drive rod in the opposite direction retracted).

The wing catching device also referred to below as a door catching device the known locking device has a Handle with which the driving pin only from the inside the door between the release position and the take-away position is movable back and forth in the present case can be retracted or extended.

If the driving pin is arranged in the driving position, so the door could only be opened from the outside to the maximum possible Open the gap opening position of the wing, if not possible would be provided, the driving pin from the outside of the To bring the door into the release position. So that the driving pin from the outside of the door from the locked position the door can be transferred to the carry position can also be opened completely from the outside the known locking device over the door catcher which also for coupling the at least one additional lock the main lock provided with the main lock coupled. For this purpose, the drive rod points in the area of the door catch device a cam attached to the drive rod, the one with the bolt retracted on one side of the driving pin in a first position and with the bolt extended on the other side of the driving pin in a second Position is arranged. When extending or retracting the Riegel therefore moves the cam between the first and the second position. When arranged in the driving position The cam acts with a lug on the Driving bolts together and transferred during its movement the driving pin between the first and the second position in the release position, so pull it into the door catch on.

The above explanations make it clear that for the transfer of the driving pin from the driving position in the Release position a closing of the main lock to extend or retraction of the bolt is required. Is the driving pin arranged in the driving position, the bolt on the other hand but not extended, the drive pin must be actuated by means of the closing element or key from Main lock first the bolt extended, the locking device be completed so that the cam on the Driving rod passes the driving pin and thereby the driving pin in the release position. But now it is Locking device completed and it needs to be unlocked again the latch will be retracted.

With the assumed constellation there is therefore a complete one Locking cycle necessary to remove the driving pin from the main lock by means of the closing element from the driving position into the Bring release position. The normal procedure when opening a door from the outside by means of a key or the like this is significantly disturbed, since usually the key is simply inserted into the lock and so long in the Opening direction is closed to retract the trap and beforehand, if necessary, to pull in the bolt until the door opens can be. In the constellation described, first in the locking direction to be closed to the driving pin in bring the release position, and only then can in the usual opening direction are closed to open the Door. The described is from an ergonomic point of view Procedure when opening the door from the outside is extremely unfavorable.

The constellation described below also makes it clear that the known locking device is ergonomically unfavorable is so that it is even easy to compromise security Incorrect operation of the locking device can occur.

Suppose a person wants one with the known locking device Open the equipped apartment door from the inside securing the door with the door catch device, for example because the person rang unknown people. The The person will then take the driving pin into the driving position bring by appropriate actuation of the door catch device. If the door is not locked, the door can now be closed by operating the door handle or the like to operate the Open the latch and the door is through the door catch against opening beyond the maximum possible gap opening position backed up. However, the door should lock so that the bolt of the main lock is extended, must To open the door, first unlock the door, i.e. the bolt be retracted. Here, however, the driving pin is now brought back into the release position. The door can now be opened So open freely if the latch is activated. To restore the safety function of the door catch device must So press the door catcher again so that the Driving pin is brought back into the driving position. A renewed operation of the door catch device may be easily forgotten. Especially people who have a special Need for the protection possible by the door catch device have, e.g. Children or the elderly may be Overwhelmed, the known locking device in the to ensure a sufficient security to operate.

There is still another possibility of incorrect operation at the known locking device can be mentioned. Possibly the person who wants to open the door from the inside tries to to keep the driving pin in the driving position correspondingly holding a handle, knob or the like. the door catcher while, if necessary, the Unlock the door, so retract the bolt of the main lock want. But if the driving pin is in the driving position held, so the drive rod is against displacement blocked in the direction corresponding to the unlocking, since the cam has to pass the driving pin. Thus leaves the door is not or only very difficultly against the handle unlock the force exerted on the door catch device.

The examples above make it clear that the known Locking device very ergonomically is disadvantageous and that the security impairment Possibilities for incorrect operation are given.

In contrast, it is an object of the invention to provide a locking device the above Provide kind that is ergonomically favorable too is operated and the incorrect operating options that impair safety largely turns off. To solve this task the characterizing features of independent claims 1 and 26 are provided.

The sequences are in the locking device according to the invention when opening the door using a closing element from the outside opposite the processes for a door with a locking device unchanged without wing catcher or door catcher. A key only needs as long as a locking element be turned in the opening direction of rotation until, possibly after previous retraction of the extended bolt, the trap is operated so that the door can be opened. The sequence is completely independent of whether the driving pin in the Take-away position or in the release position is arranged. Is the driving pin in the driving position, but the door not locked, so the bolt is not extended, so the driving pin when the latch is actuated by means of the Locking element from the main lock to the release position transferred, with a locking element in the form of a key, as stated, rotated in the usual opening direction becomes. The partial or complete completion of a locking cycle for transferring the driving pin into the release position is under in the locking device according to the invention no circumstances required.

The above-mentioned options for incorrect operation when opening a door from the inside are also essentially turned off. Under the circumstances set out above, a person who wants to open a door with a limit of the maximum possible gap opening position by the door catch or wing catch device and after transferring the driving pin to the driving position by corresponding actuation of the door catch device determines that the door is still locked, unlock the door by means of the closing element, without this the driving pin is brought back into the release position becomes. The person now opens the door using the latch by means of the door handle or the like, so is the driving pin despite the previous unlocking of the door, it is still in the driving position and the door catcher can do its safety function meet, i.e. limit the opening angle of the wing, to get outside access to the apartment without the consent of To prevent person in the apartment.

In the locking device according to the invention, the second possibility of incorrect operation mentioned above, i.e. blocking the main lock through the wing catcher, by appropriate design of the main lock, the wing catcher or the way of coupling the main lock and the wing trap easily turned off are, as from the following explanations in individual can be seen.

The coupling of the main lock and the wing catcher can via a the latch actuator and the driving pin actuator connecting connecting element be made. The connecting element can be on the main lock side with one of the closing element, if necessary, via the bolt actuation device actuated sub-device of the latch actuating device keep in touch. Especially at electrically operated actuators come one electrical connection by means of a signal line or the like. in Consideration.

Compared to an electrical coupling is a mechanical one Coupling of the main lock and the door catch device preferred. The connecting element can then be a tension element, possibly a Pull wire or a pressure element, preferably a drive rod, be. Such a construction of the locking device ensures high functional reliability.

For transferring the driving pin from the driving position to the release position from the main lock can be the connecting element by a trap, also as Change designated latch lever to be operated. Prefers the connecting element for transferring the driving pin from the take-away position to the release position with a tractive force. It is particularly useful if the pulling force from the latch lever onto the connecting element when pivoting the latch lever to retract the latch is transmitted. The transmission of traction from the latch lever on the connecting element is preferably carried out by means of a rotatably mounted transfer lever, of which preferably one Lever arm with an end portion of the latch lever near the latch Intervention can be brought. Compared to a locking system without The wing lock needs the main lock for the invention Coupling with the wing catcher only be modified slightly, and it is sufficient within the Main lock an additional, rotatably mounted part for Power transmission between the possibly extended latch lever and the connecting element. The manufacturing effort and accordingly the manufacturing costs thus increase only marginally.

The locking device can be designed such that the Driving bolts from the main lock from the release position in the take-away position can be transferred, for example by corresponding actuation of the driving pin actuating device via the connecting element. Regardless of this the driving pin actuator is a manual sub-device have to move the driving pin manually between the take-away position and the release position, in particular by means of a rotary knob or the like. The wing catcher is particularly easy in this way, operate especially from the inside of the door.

To implement the coupling according to the invention between the Wing catcher and the main lock via the connecting element preferably has the driving pin actuator a further sub-facility by the Connection element or the manual sub-device can be triggered is arranged for transferring the in the driving position Driving bolt into the release position by the other Partial facility. There are special advantages if the further sub-device has an energy accumulator, which at Transfer of the driving pin from the release position to the Carrying position is loaded and the driving bolt in the direction preloaded for release position. The lift mechanism can by spring means, in particular at least one tension spring, be educated. The energy accumulator ensures that Transfer of the driving bolt arranged in the driving position only an extremely small force in the release position must be applied in the main castle (especially only one extremely low force from the latch lever to the connecting element must be transmitted) to trigger the further sub-device. The to operate the latch by the closing element The force required is therefore only increased insignificantly. As another Gear means for coordinating the movement of the Driving pin and the trap such that the driving pin has reached the release position when the trap has been drawn in, omitted.

According to the training described, the driving pin must Transfer of the driving pin into the driving position by Triggering the other sub-device in the carry position being held. For this purpose, the further sub-device can be corresponding Latching means for holding the driving pin in the Have a take-away position.

There are many options, such as the wing catcher can be built internally. According to a preferred variant is the driving pin on a slidably mounted Fixed slide element on which the energy accumulator attacks. Furthermore, the locking means for holding the driving pin a catch recess on the slide element in the driving position and have a movable locking element, wherein the locking element has a locking engagement portion and the locking element with the driving bolt arranged in the driving position in a Locking engagement position can be brought in which the locking engagement section is engaged with the recess. To trigger the further sub-device, it is then sufficient that the Locking element is moved such that the locking engagement section disengaged from the recess.

Also with regard to the design of the locking element itself diverse configurations conceivable. So the locking element be designed as a sliding element, the locking element preferably in a direction of displacement of the slide element essentially displaceable in the vertical direction of displacement is. Spring means can also be provided, in particular at least one compression spring which the locking element in the direction of Preload engagement position.

For coupling the wing catcher and the main lock No great effort is required via the connecting element become. So the connecting element to trigger the attack another sub-device directly on the locking element.

As already mentioned, the manual sub-device is preferred actuated by means of a rotary knob or the like. In this The manual sub-device can be a rotary knob or have associated knob nut or the like, the one with a first driving section directly on the locking element attacks to trigger the further sub-device. The knob nut or the like preferably has a second one Driving section, in particular a driving arm, on the Carriage element attacks, possibly in a driving recess of the slide element engages to transfer the Driving pin from the release position to the driving position. The knob nut or the like can be used for transfer of the driving pin from the release position to the driving position from a first assigned to the release position Rotary position in a second assigned to the driving position Rotational position can be rotated, with the knob nut in the Driving position arranged driving pin with the locking element is engaged and by the locking element in the second The rotational position is held until the further partial device is triggered. After triggering the further sub-device the pommel then by the power of the energy storage to transfer the driving pin back to the release position moved carriage element rotated back to the first rotational position. With the latter training can be rotatably Coupling the knob or the like. With the knob nut or Identify immediately from the position of the knob whether the Driving pin in the driving position or in the release position is arranged.

In principle, there are many options with regard to the Construction and execution of the gap opening limiter. For example the gap opening limiter could be one in the direction slidably mounted perpendicular to the frame plane, with a wing distal end on a frame-fixed fitting part striking, elongated rod element. Also a formation of the gap opening limiter using a chain may come into consideration. Training is preferred of the gap opening limiter as a swivel bracket, the Swivel bracket at one end on the fixed frame or on a fixed frame side Fitting part is pivotally articulated and as an engagement section a substantially in the longitudinal direction of the Has pivoting bracket extending backdrop. Conveniently is the swivel bracket around a to the fixed frame level essentially parallel swiveling axis.

A high level of functional reliability with a swivel bracket as Gap trap is designed for the gap opening limiter reached when the backdrop with a first backdrop section a first backdrop width and a second backdrop section with a second backdrop width larger than the first backdrop width has, the second link section to one End of the swivel bracket is closer than the first link section, if the driving bolt also has a bolt head a transverse dimension smaller than the second backdrop width and larger than the first link width and if the driving pin a driving section adjacent to the bolt head has a transverse dimension smaller than the first link width, if the bolt head is also closed Wing when transferring the driving pin from the release position in the driving position through the second stage section passes through and when the driving pin after passing through of the bolt head through the second link section and after reaching the driving position with the driving section engages in the backdrop, the driving section when opening the wing by pivoting the Swivel bracket from the second backdrop section to the first Scenery section occurs and after reaching the maximum possible gap opening position of the wing on one of the End of the swivel bracket strikes the far end of the link.

In particular for additional security of a closed door from the inside without the need to lock the door proposed according to another aspect of the invention, the Execute wing catcher in such a way that a Locking the door is possible. In this context it is preferred that the driving pin with closed wing of the release position beyond the take-away position into a Locking position can be brought in which he the wing on the frame the wing closed position locked especially by engagement into the fixed frame side designed as a striking plate Fitting part through the second link section.

Conveniently, the driving pin should also come from the locked position in the release position from the main lock at the Actuation of the trap can be transferred using the closing element be. The locking means can take the driving pin after transfer the driving pin in the locked position, in particular by means of manual part of the device, hold it in the locked position until the further sub-device is triggered, the latching means in particular a further recess on the slide element include the arranged in the locked position Driving pin in the locking engagement position of the locking element engages with the locking engagement portion of the locking element stands.

The locking device can be at least one of the main lock separate and coupled with this additional lock with a Have additional bolt, which with the help of an additional bolt actuator of the additional lock from the main lock can be actuated. The additional bolt is expediently used for Actuation of the bolt operated by means of the closing element.

The coupling of the main lock and the additional lock can via a bolt actuation device and the additional bolt actuation device connecting connecting element be made. In the case of a mechanical coupling of the The main lock and the additional lock is a separate one another connecting element, in particular in the form of a Driving rod, provided in addition to the connecting element for coupling the main lock and the door catch device. The Connection element and the further connection element are preferably one above the other or side by side in a sash groove or the like. Movable relative to each other, wherein preferably the further connecting element over the connecting element is arranged and possibly the further connecting element covered to the outside by a cover rail or the like is.

In another aspect, the invention relates to a door or Like. With a locking device as described above.

The locking device 100 shown in FIGS. 1, 3 and 4 has an espagnolette lock 102 as the main lock and one Wing catching device 104 on a wing 108 and a Espagnolette lock or main lock 102 associated locking plate (not shown) and a gap opening limiter 106 am Fixed frame 110. In the example shown, the wing is 108 a door wing and it is therefore appropriate to use the wing catcher 104 can also be addressed as a door catch device 104. The door catch device 104 is connected via a drive rod 112 coupled to the main castle. It is also another drive rod 116 provided for coupling the main lock with other components of the locking device, in particular with at least one additional lock (not shown).

Before closer to the door catch device 104 and their interaction with the main lock 102 or the gap opening limiter 106 will be discussed in advance briefly on how it works of the main lock or espagnolette lock 102 become. The main castle is in Figure 1 for clarity only drawn incompletely, and it is therefore based on referenced to FIG. 2, which is of essentially the same structure, in minor details in the present context but drive rod lock deviating from the main lock of FIG. 1 shows.

The espagnolette lock of FIG. 2 has a profile cylinder 1 on, the (not shown) lock bit hub by a Gear ring 10 is surrounded, which for the coupling with the lock bit has a slot 2, the lock bit in the area of two drive gears 12, 12 'not to the root diameter of the ring gear 10 reaches. The ring gear 10 is with a flange outer circumference guided in a bearing 14 fixed to the housing and meshes with the two drive gears 12, 12 '.

The drive rod lock has a drive rod 16 and one Latch 18, the locking and unlocking operation by two rotations of the lock cylinder 1. At the End of a reduction gear A, which from the gears 10, 12; 12 ', 13 and 15 is a drive rod drive pinion 20 with one on the front side of the lock cover fixed control element 22 mounted. The control 22 is shaped at both ends with approximately circular Control cams 24, 24 'are formed, which upon closing operation through the lock cylinder one after the other in corresponding Recesses 26, 26 'engage the drive rod 16 and move them.

Arranged on the axis 34 of the near the drive rod 16 Gear 12 is coaxial with a transfer lever 35 stored, which partially overlaps a bolt tail 36. With a fork-like arm 38, it comprises one Pin 40. A second arm 50 of the transfer lever 35 protrudes into one Drive rod recess 42 of the drive rod 16, which with cams 46, 46 'provided with rectangular control surfaces 44, 44' is limited.

When excluding the drive rod 16 and the bolt 18 comes the lower control surface 44 of the upper cam 46 on the second Arm 50 of the transfer lever 35 to the system and pivoted it counter clockwise. Through the pin-slot connection 38, 40 the bolt is excluded (extended). After double locking rotation of the profile cylinder 1 is the bolt 18 fully extended, and the arm 50 is then supported on the Face 52 of the upper cam 46. At the same time is a drive rod-fixed pin 54 behind a shoulder 56 of the bolt 18 pushed.

The drive rod 16 serves, as already in relation to the Locking device of Figures 1, 3 and 4 mentioned, for coupling of the main castle, for example, with at least one in the Figures additional lock of the locking device, not shown, the additional lock is synchronized by means of the drive rod 16 with the bolt 18 operable additional bolt for engagement in a fixed frame side striking plate.

Others, in particular for actuating the drive rod 16 or Components of the bolt 18 are: a stop cam 28 and curved limiting fingers directed into the castle interior 30, 30 '. The axis of rotation of the drive rod drive pinion 20 is designated by 32 in FIG. The lock faceplate, especially in Shape of a cover rail, is designated 3.

The main lock has a latch 78, which is a follower 80 of a door handle and actuated from the lock cylinder 1 is. A trap tail 58 of the trap 78 is in between the castle floor 60 and the castle ceiling 62 slidable Housing 64 attached, housing 64 for guidance its broad sides two opposite longitudinal slots 66, 66 ', in each of which on the castle floor 60 and short guide pins 68, 68 'arranged in the lock cover 62 intervention. The rear wall of the housing 64 is 70 designated and connected to the trap tail 58.

To pull the latch 78 through the door handle, the handle follower 80 swiveled clockwise by approx. 45 °, with one on the follower nut 80 integrally molded driver 82 behind a shoulder 84 of the housing 64 engages. The follower nut is 80 towards the extended trap 78 through a into a spring case 86 used compression spring 88 biased, which Slidable spring housing 86 with a plunger 90 in one Recess 92 engages the follower 80. The trigger nut 80 is based in the normal position on the lock floor 60 and from the castle ceiling 62 connecting pin 94.

For the latch actuation by means of the lock cylinder 1 is on Lock bottom 60 coaxial with the drive rod drive pinion 20 Trap lever 96 pivotally arranged, which with its free End 98 abuts the housing 64. The gear connection to The latch lever 96 includes one on the front side of the lock bottom of the drive rod pinion 20 arranged driver 21, the with the bolt 18 closed and further rotation of the Lock cylinder clockwise on a nose 97 of the latch lever 96 comes to rest and the latch lever 96 (also frequently referred to as a change) pivoted clockwise to retract the trap 78.

With regard to further details of the structure and functionality the espagnolette lock of Figure 2 is on the DE 39 01 223 C2, the figure 1 of the present figure 2 underlying. Also a possible embodiment of the additional lock or the additional bar can this German Remove patent specification.

Compared to the drive rod lock known from DE 39 01 223 C2 is the espagnolette lock of the present FIG. 2 changed so that the latch lever 96 on its free End extended beyond the housing 64 for training an operating end portion 98a for operating an additional one Drive rod 112 'via a transfer lever 114' (the additional Driving rod 112 'and the transfer lever 114' are thus compared to the drive rod lock known from DE 39 01 223 C2 additionally provided). The additional drive rod 112 ' serves to couple the main lock with a corresponding one Wing catcher or door catcher (as in the following based on the embodiment of Figures 1, 3 and 4 in more detail explained); this additional drive rod 112 'is the following for easier distinction as driving pin driving rod 112 '(or 112 with respect to the embodiment of the Figures 1, 3 and 4) are referred to as for coupling of the auxiliary lock and the main lock serving driving rod 16 in the following as additional bolt drive rod 16 (or 116 with regard to the exemplary embodiment in FIGS. 1, 3 and 4) should be designated.

Referring to Figures 1, 3 and 4, the wing trap has 104 a driving pin 120, which on a Slide element 122 in a housing 124 of the door catch device 104 is slidably mounted, the driving pin 120 in a first sliding position of the slide element protrudes from the housing 124 and from the wing protrudes on the face plate (this is called the driving position of the driving bolt referred to) and in a second shift position of the carriage element 122 is drawn into the housing 124 (this is referred to as the release position of the driving pin 120).

The additional bolt drive rod 116 is on the cuff side of the housing 124 passed and has an elongated hole 126, so that the Driving pin 120 in each position of the additional pin drive rod 116 extended from the housing 124, that is in the driving position can be arranged. The additional pin drive rod is on the outside 116 from one also on the housing 124 cover rail 128 guided past the faceplate, the one Has hole 130 for the passage of the driving pin 120.

The slide element 122 can be moved from the one shown in FIG. corresponding to the release position of the driving pin 120 Shift position by means of a rotary knob, not shown in the shift position shown in Figure 1a and Figure 4 corresponding to the driving position of the driving pin 120 convict. For this purpose, the rotary knob with a knob nut 132 rotatably connected, which is rotatably mounted in the housing 124 is. The knob nut has a drive arm 134, which with a driving recess 136 of the slide element 122 in Intervention stands. Furthermore, the knob nut 132 has a driver section 138 on, which is displaceable in the housing 124 stored locking element 140 with the direction of displacement of the slide element 122 orthogonal direction of displacement cooperates.

The door catch device 104 also has two tension springs 142 and a compression spring 144. The tension springs act between the Housing 124 and the carriage member 122 and act on it Slide element 122 with a tensile force parallel to the direction of displacement of the sled member 122 toward that of the Cover rail 128 opposite housing wall 124a, i.e. in the direction from the driving position of the driving bolt corresponding displacement position of the slide element 122 that corresponding to the release position of the driving pin 120 Sliding position of the slide element 122.

The compression spring 144 acts between the housing 124 and the Locking element 140 and loads the locking element 140 with a Compression force parallel to the direction of displacement of the locking element 140 from a lower housing wall 124b towards the slide element 122. The locking element 140 has a locking finger 146 as Latching engagement section, the upper end portion at in the driving position arranged by the Compression spring 144 engages with a recess 148 on Carriage element 122 is pressed to hold the carriage element 122 in the driving position of the driving pin 120 corresponding shift position against that of the Tension springs 142 exerted tensile force on the slide element 122.

The functioning of the door catch device with regard to a manual actuation of the driving pin by means of the rotary knob is as follows. Starting from the position shown in Figure 1b pushes or shifts when turning the knob nut 132 in the to Clockwise opposite direction through the rotary knob the driving arm engaging with the driving recess 136 134 the carriage element 122 against the tensile force the tension springs 142 to the front, i.e. in the direction of the cover rail 128, the driver section 138 the latching element 140 pushes downward against the pressure force of the compression spring 144, so that the end portion of the latch finger 146 from the sled member 122 is moved away to free movement of the slide member 122 to enable. After turning the knob nut by 90 ° is the driving position of the driving pin 120 corresponding displacement position of the slide element 122 reached, and the driver portion of the knob nut 132 gives that Locking element 140 so far free that the end portion of the locking finger 146 into the recess 148 due to the pressure of the Spring 144 enters and the carriage element 122 in the reached Position, and thus the driving pin 120 in the driving position, holds. Due to the driver section striking 138 on one side at a stop 150 and one engaging on the other side with the locking element 140 is the knob nut 132 in the rotational position reached against further rotation counterclockwise and against unintentional turning back clockwise held carriage element 122 secured.

The driving pin 120 is to be returned to the release position be transferred by operating the rotary knob, so is the rotary knob and thus the knob nut 132 in the clockwise direction to turn back, due to the engaging of the Driver section 138 and the locking element 140 an initial Overcoming resistance when turning the rotary knob is. By turning the knob nut 132, the locking element 140 against the pressure force of the compression spring 144 downwards pressed, with the end portion of the latch finger 146 except Engagement with the locking recess 148 of the slide element 122 brought. As soon as the locking finger 146 and the locking recess 148 are disengaged, the rotary knob does not need to go any further Be turned clockwise since the tension springs 142 the slide element back to the starting position, and thus pull the driving pin 120 into the release position. Here we the knob nut 132 through the driver recess 136 and the Driver arm 134 rotated back to the original rotational position, the clockwise rotation by a stop 152 is limited, on which the driver section 138 abuts.

The gap opening limiter 106 is designed as a swivel bracket, which is fixed to a fixed frame by means of a hinge pin 160 Fitting part 162 is pivotally articulated with a closed Wing to move the slide element 122 substantially parallel pivot axis. Expressed differently, is the one running in a horizontal plane Swivel axis of the swivel bracket 106 parallel to the fixed frame plane or with the wing closed, parallel to the wing plane. The fitting part 162 is attached to the shape of the by screws 164 Fitting part 162 adapted recess 166 of the fixed frame 110th screwed to the fixed frame 110, with the recess 166 on the side closer to the door leaf 108 when the door is open is open so that the pivot lever 106, as shown in Figure 3, from a vertical position shown in dashed lines in FIG. 3 can swing out. The swivel bracket is without external influence 106 arranged in its vertical position due to gravity.

The swivel bracket 106 has a (also as a hole or opening significant) backdrop 168 with a first backdrop section 168a and a second link section 168b. The link section 168a extends with a constant width parallel to a longitudinal axis of the swivel bracket and takes the most of the scenery 168. At the first stage section 168a closes the substantially circular one Link section 168b, the diameter of this second Link section 168b the width of the first link section 168a noticeably exceeds, so that the in FIG well-recognizable, keyhole-like backdrop shape results. The driving pin 120 is coordinated with the backdrop 168 its outstanding in the driving position from the housing 124 End a bolt head 170 on which towards housing-inside end of the driving pin 120 in the following referred to as driving section 172 section of the Driving pin 120 connects. The diameter of the bolt head 170 exceeds the diameter of the driving section 172 and the width of the first link portion 168a, but is smaller than the diameter of the second link section 168b. The diameter of the driving section 172 is smaller than the width of the first link portion 168a.

Now the driving pin 120 with closed wing in the Transfer position, the bolt head 170 passes through through the second link section 168b, so that the driving section 172, as can be seen in FIG. 4, into the backdrop 168 engages in such a way that the bolt head 170 on the near the fixed frame Side of the swivel bracket 106 and from the driving section 172 at least a short section on both sides of the Swivel bracket 106 is arranged. When opening the door leaf 108 the driving section 172 strikes against the backdrop 168 delimiting backdrop edge 174 and pivots the swivel bracket 106 when the door leaf 108 is opened further from the vertical position, the driving pin 120 with its driving section 172 slides on the edge of the backdrop 174 and from that second link section 168b into the first link section 168a occurs. The door leaf 108 can be opened until the driving section 172 removed from the hinge pin 160 lying backdrop end 176 or the corresponding section of the backdrop edge 174 strikes. The swivel bracket 106 limits So the opening angle of the door leaf to a maximum possible Gap opening angle. While swinging the The swivel bracket 106 engages behind the bolt head 170 in the first Link section 168a the link edge 174, so that the driving pin 120 reliably engages with the backdrop 168 is held and can not escape from the backdrop.

When the gap-open wing closes, the moves Driving pin 120 in relation to the backdrop 168 again in the direction to the second link section 168b, the pivot lever 106 synchronously swings back towards its vertical position. With the wing closed position the driving pin reaches 120 the second link section and the swivel bracket 106 its vertical position. Now the driving pin 120 back into the release position by pressing the appropriate button the rotary knob are transferred, for example to normal Opening the door.

A return of the driving pin 122 from the driving position in the release position can also from the main lock respectively. This mode of operation of the door catch device 104 is especially important to always have a door, that is, from the current one Position of the driving pin independent, open from the outside to be able to. According to the driving pin 120 from Main lock 102 off only when the latch 178 is actuated of the locking element, here a key, from the driving position transferred to the release position. The coupling of the The main lock 102 and the door catch device 104 take place about the already mentioned driving pin driving rod 112. An The driving pin driving rod engages at the end of the door catch device 112 on the locking element 140 such that a tensile and pressure resistant connection between the locking element 140 and the drive pin driving rod 112 is made. For this a lateral tongue section 180 of the locking element 140 engages into a side fork section 182 on the driving pin driving rod 112 a.

The main lock end of the drive pin driving rod 112 stands over a lateral fork section 184 of the drive rod 112 with a first arm of two arms of the one in the main lock rotatably arranged transfer lever 114 in constant engagement, which transfer lever 114 the transfer lever 114 'of the main lock corresponds to Figure 2. The driving pin driving rod 112 and the transfer lever 114 are motionally coupled so that each Rotary position of the transfer lever 114 is a shift position of the Driving pin driving rod corresponds. Are in the same way the locking element 140 and the driving pin driving rod 112 motion-coupled (every displacement position of the locking element 140 corresponds to a displacement position of the driving pin driving rod 112), so that a movement coupling of the Transfer lever 114 and the locking element 140 results (any shift position the locking element 140 corresponds to a rotational position of the transfer lever 114).

The driving pin 120 assumes its driving position (cf. 4 and Fig. La), so is the second arm of the transfer lever 114th arranged such that it is in the pivoting range of the end portion 168a of the latch lever 196 reaches. Now how explained above with reference to the drive rod lock of FIG. 2, the latch lever 196 operated by means of the key to Retraction of the trap 178, so the twisted in the representation of the Figure 1 clockwise pivoting latch lever 196 the transfer lever 114 counterclockwise so that the drive pin driving rod 112, and thus the locking element 140, itself move down and the locking finger 146 out of the locking recess 184 exits. The locking element 140 thus holds the slide element 122 no longer tight, so that the tension springs 142 den Driving pin 120 via the slide element 122 into the release position pull, the knob nut 132 from that in Figure 1a shown rotary position back to that shown in Figure 1b Is rotated as described above.

As can be seen in FIG. 1b in comparison with FIG the compression spring 144 when arranged in the release position Driving pin 120 the locking element 140 not so far up move as with the arranged in the carry position Driving pin 120. Opposite the sliding position of the locking element 140 in Figure la with arranged in the driving position Driving pin is the locking element 140 through the driver section 138 the knob nut 132 according to FIG. 1b in the Release position arranged driving pin 120 down postponed. Accordingly, the transfer lever 114 is opposite the rotational position of Figure 1a rotated counterclockwise (Figure 1b) when the driving pin 120 in the release position is arranged. The second arm of the transfer lever 114 engages this rotational position of the transfer lever 114 no longer in the Pivot range of the end portion 198a of the latch lever 198, so that the latch lever can swing freely back and forth to Retract the trap 178 and retract the trap 178.

From the description of the main lock of Figure 2 results the movements of the driving pin driving rod 112 and the additional bolt drive rod 116 are independent of each other. The auxiliary pin drive rod 116 becomes synchronous with the actuation of the bar not shown in Figure 1 in one or in the shifted in the other direction, whereas the driving pin drive rod 112, and thus the locking element 140, when actuated of the bolt maintains the respective sliding position and accordingly also the driving pin 120 in its respective Position remains. For a displacement of the driving pin driving rod 112 occurs only when in the take-away position arranged driving pin 120 of the latch lever 196 by corresponding actuation of the main lock 102 by the Key to retract the trap 178 in the direction of retraction Trap 178 pivots and thereby on the transfer lever 114 on the Driving pin driving rod 112 pulls. The locking finger 146 comes then out of engagement with the locking recess 148 on the slide element 122, and it comes when transferring the driving element 120 in the release position for a further shift of the Driving pin drive rod 112 corresponding to the displacement movement of the locking element 140 under the influence of the moving Slide element 122 and the rotating knob nut 132.

A second exemplary embodiment will now be described with reference to FIG a locking device according to the invention are explained, being compared to the embodiment of Figures 1, 3 and 4 only differences regarding the design of the door catch device and the fixed frame-side bearing the swivel bracket Fitting part exist. Components of the second embodiment, which function according to those of the first embodiment according to Figures 1, 3 and 4 are the same Reference numbers, however, each increased by the number 100 Mistake. It will only look at the differences between received two embodiments and the rest expressly to the previous description of the first Embodiment referred.

In the door catch device 204 of FIG. 5, the driving pin can be used 220 about the driving position shown in Figure 5a moved further out of the housing 224 into a locked position in which the bolt head 270 in when the wing is closed a locking recess 290 in the fixed frame fixed fitting 262 engages and locks the sash on the fixed frame (see Figure 5b). The recess 290 is essentially aligned with the second link section 268b in the vertical position arranged swivel bracket 206. The bolt head 270 is circular cylindrical in contrast to the end tapered bolt head 170 of the first embodiment.

Compared to the slide element 122 of the first embodiment is the displacement element 220 for realizing the required larger displacement strokes shorter in the direction of displacement executed and has a second locking recess 249, the with the free end of the locking finger 246 of the locking element 240 in Can be engaged to hold the slide member 222 in that corresponding to the locked position of the driving pin 220 Shift position. The two recesses 248 and 249 on Slide element 222 and the free end of the locking finger 246 are opposite the locking recess 149 and the free end of the Locking finger 146 of the first embodiment in the direction of displacement of the sled element executed narrower.

The transfer of the driving pin 220 from the release position into the take-away position shown in FIG. 5a takes place as described above in the first embodiment. The further Extending the driving pin 220 from the housing 224 into the The locking position is also achieved by turning the knob nut 232 about the rotational position shown in Figure 5a counterclockwise. The driving arm 243 of the knob nut 232 is opposite extended the driving arm 134 of the first embodiment, so that it slides the carriage 222 over that shown in FIG Press the position towards the end of the casing on the forend can. To allow this additional rotation of the knob nut 232, the stop 250 is opposite the stop 150 of the first embodiment offset upwards.

As long as the slide element 222 through the locking element 240 in the corresponding to the driving position of the locking pin 220 Position is held (by engaging the free end of the Locking fingers 246 in the first locking recess 249) can be however, the driving pin 220 is not in the locked position convict. To release the slide element 222, this has Locking element 240 one from the housing 224 by a corresponding one Elongated push handle 292 on, by means of which the locking element 240 can be pushed down to Release of the carriage element 222 around the driving pin 220 from the take-away position to the locked position or directly from the release position in the blocking position by means of a corresponding Bring the rotary knob to bring.

If the driving pin 220 from the locked position back again are transferred to the release position, this is done by the door catch device by operating the rotary knob like described above, i.e. by turning the rotary knob clockwise as shown in Figure 5, or alternatively by corresponding actuation of the push handle 292, that is by immediately shifting the locking element 240 below, so that the engagement between the free end of the locking finger 246 and the second recess 249 is lifted. In the same way, the locking element 240 can also be used for transfer of the driving pin 220 from the driving position into the release position actuated directly by means of the push handle 292 become.

The transfer of the driving pin 220 from the locked position or from the take-away position to the release position from the main castle as described above. When pressing the Trap by the key becomes the driving pin driving rod 216, and thus the locking element 240, on the latch lever and the transfer lever moved so far that in the case of a Locking position arranged driving pin 220 of the driving pin 220 reliable the release position through the action of Springs 242 reached without the free end of the locking finger 246 can enter the first recess 248, so that the driving pin is never in the driving position stop. So, for example, the door from the outside of the key opened, the door can be opened accordingly Always turn the key to retract the trap open immediately, regardless of whether the drive pin previously in the release position, in the take-away position or in the Locked position was arranged.

In summary, the invention relates to a locking device for a door or the like with a fixed frame and a key, comprising a main lock and a wing catcher on the wing, with a drive pin of the wing catcher with a gap opening limiter provided on the fixed frame Intervention can be brought. The main lock and wing guard are coupled to each other in such a way that the driving pin from the main castle only when the case of the Main lock by means of a locking element out of engagement with the gap opening limiter can be brought.
