Abstract

The at least two bolts are positioned on the door-leaf and engage into a locking opening (46) in the door frame. The two bolts are mounted in an additional lock (14,16) and are operated by a door handle mounted on a main lock or and by a lock in the main lock. The second especially swivel bolt (24) and or the second locking opening has or have a sloping part.

Description

The invention relates to a door lock arrangement, preferably espagnolette lock arrangement, according to claim 1.

From DE 38 22 343 A1 a Schlossanordung is known in the opposite direction pivotable locking lever (22, 24) in one Additional lock are stored and each slide over, through Twisting a handle in parallel, but in opposite directions are displaced, by a release position (B) in a locking position (C) with engagement in a locking opening (100, 102) are moved. The additional lock has a own housing (2), which on a window or on a Patio door can be screwed on. For actuating the locking levers (22, 24) is the additional lock with the existing window fitting already contained handle (82) via a common drive pin (36) connected.

The use of multiple pivot bolt in a espagnolette is also from the prospectus Carl F. Petersen, Ltd., "Fuhr Multisafe Technology for high-security standards. "For each of the two pivot bars each provided a separate door frame side strike plate. Also Both pivot bars are each in a separate additional lock pivoted. The locking and unlocking of the pivot bolt can be done from the door handle or, as usual, from the cylinder lock. The Both striking plates must be mounted exactly on the door frame during installation be, namely in a the distance of the pivot bolt on the door leaf exactly the appropriate distance, otherwise possibly only one of the two Latch attacks.

From EP 0 634 552 B1 is in itself a drive rod actuated pivot bolt known, which is provided with a suit bevel. at corresponding actuation of the cylinder lock provides in the associated Locking opening of the door frame pivoting pivot bolt for an increasing suit of door leaves and door frames. One achieves so readily the required sealing, in particular windproofness, the door required to comply with heat protection regulations.

The invention has for its object to provide a door lock assembly of to provide the aforementioned type, on the one hand high burglary protection provides, if the door is only pulled or closed, and on the other hand good sealing of the door allows.

This object is solved by the features of claim 1.

Thus, according to the invention, the closing door always has at least one first pivot bolt of the mounted in an additional lock pivot bolt pair automatically locked. In addition, if the lock, preferably Cylinder lock, is operated, is about the at least one second Pivoting bolt on the basis of the one attached to the second pivot bolt and / or the second locking opening Tightening bevel and the door to the door frame pulled to manufacture the Door tightness, wherein the at least one second pivot bolt the burglar resistance elevated.

The second latch is designed as a pivot bolt, as a result, the effective length of the tightening bevel compared to a linearly movable pivot bolt with limited depth of penetration into the Strike plate can be increased.

One could think of using only the first pivot bolt, namely with self-tightening function. However, this would have several disadvantages. Around to achieve sufficient self-sufficiency, would have a correspondingly strong Preloading spring can be used. Conversely, then, would be for withdrawal the first pivot bolt, in particular from the cylinder lock, a correspondingly high actuation force required, which is essential to the operation would complicate. Also would be inappropriate Operation, i. upon release of the lock by the first pivot bolt of Hand (for example, by pressing the actuating pin), a not inconsiderable Risk of injury exist as the under strong spring preload standing pivot bolt would emerge with appropriate force. In addition, would when disengaging the swing latch when closing the door a lot of noise arise. On the other hand, the first pivot bolt for safety of large Meaning, as this automatically engages when the door slammed is, i. regardless of whether the door is properly over the Cylinder lock is locked. According to the invention, therefore, the Selbstanzugsfunktion taken from the second swing bars.

To simplify manufacture and assembly, it is proposed that both locking openings for the pair of pivot bolt on a common door frame-side closing part, preferably closing breech, are formed. So it's just a single strike plate for the two Manufacture, supply and assemble bars. The danger of Maladjustment is greatly reduced.

In a further development of the invention it is proposed that the pivot bolt of the pair formed as a latch hook for engaging behind the closing part are, with their free ends in their locking positions from each other lead away or converge. One receives in this way one common clawing of the locking hook pair on the common closing part, which greatly increases the security against burglary, especially because of a Pull off the latch hook away from the closing part only under strong deformation the latch hook and / or the closing part is possible. Latch hook and However, closing part can also be very solid and thus easily be formed as an obstacle.

additionally It is proposed that the two pivot bolt of the pair in a common latch housing are mounted. This measure also reduces the manufacturing and assembly costs while increasing the Burglar resistance, as an unauthorized removal of the two latch hooks from each other to solve the mutual clawing on the closing part at Bearing of the two pivot bolts in the common bolt housing is much more difficult compared to the storage in each case one separate latch housing.

It is also proposed that the at least one first and the at least one second pivot bolt or the two pivot bolt of the Paares means of drive rod, Bowden cable or the like. Mechanically actuated and / or electromechanically actuated. As an example of the espagnolette of bars is to DE 38 36 693 C2 noted, but does not disclose a pair of pivot bolt. The function of the drive rods can also easily Take over Bowden cables or the like. Also an electromechanical Actuation via corresponding servomotors is conceivable.

The at least one first pivot bolt can in its locking position be spring-loaded. Also, a releasable locking device for the provided at least a first pivot bolt in its locking position be.

The invention will now be described in terms of preferred embodiments explained with reference to the drawing.

The door lock assembly 10 shown schematically in Figure 1 consists door leaf side of a central lock 12 and an upper and a lower additional lock 14 and 16, wherein in the illustrated embodiment the central lock 12 with the two additional locks 14, 16 each connected via a cuff rail drive rod section 18. As indicated in Figure 1 by dash-dot lines, but also comes another type of coupling in question, for example via Bowden cables or via electrical lines with servomotors in the housings 20 the two additional locks 14, 16 are connected. These servomotors drive the pivot bolt pivotally mounted in the additional locks 22, 24 on.

The one of the two bars, for example the upper pivot bolt 22 can be automatically pressed or pulled disengage the door, namely, it is triggered by a separate actuating pin 34 and the other pivot bolt 24 is from Cylinder lock operated.

The cylinder lock to be operated from the pivot bolt preferably provided with a suit bevel 30, as indicated on the lower pivot bar 24 according to FIG. 1B. When swinging out the pivot bolt to engage in the associated Pivot bolt opening of a closing part, in particular striking plate 32, Accordingly, the door is increasingly attached to the door frame attracted (in the direction perpendicular to the wing plane).

Are both bars 22, 24 disengaged, this results in a "claw" on Striker 32, which increased resistance to a break-in attempt opposes.

The mentioned suit bevel 30 provides a sufficient door seal for sure. The suit bevel can alternatively also inside the Keep plate 32 may be provided so that then trained tie 22, 24 can be used. It is also conceivable both bars as also form strike plate with tightening bevel.

To figure 1 it should be added that the central lock 12 has usual structure until on the installation of the actuating pin 34. One recognizes a common case 36, which is operable from the nut 28 and possibly also from the opening 26 inserted cylinder lock (quarter turn). Also is a common one linearly extendable locking bolt 38 indicated that exclusively from Cylinder lock is out and retractable. A the central castle 12 associated strike plate 40 has corresponding receiving openings 42nd for locking bolt 38 and latch 36. The two additional locks 14 and 16 assigned. Striker plates 32 are accordingly with a for both pivot bolt 22, 24 common locking opening 46th educated.

In Figures 2 to 4, the type of automatic actuation of Actuating pin 34 when closing the door explained schematically. you recognizes that on a door frame 48, for example via mounting screws 50, mounted strike plate 40, which in the area of the Wing-facing outer edge 52 with an inlet inclined surface portion 54 is provided at the level of the actuating pin 34. It closes a vertically extending section 56 perpendicular to the frame plane on, which then merges into a pin receiving opening 58. The sections 54, 56 and the receiving opening 58 form a control surface for the actuating pin 34th

The actuating pin 34 is in a housing 60 of the central lock 12th mounted linearly displaceable, wherein the housing 60 in a corresponding Recess of a door 62 is inserted. The inner structure of the shown upper portion of the central lock 12 is roughly schematic indicated. It can be seen a biasing spring 64, the actuating pin 34 in the illustrated first position (fully extended position) biases. It also recognizes a symbolized as a block PositionFeststelleinrichtung 66. This determines whether the actuating pin 34 is in his second (indented) position is (in Figure 2 dash-dotted ) Indicated. If this is the case, the locking device 66 causes that the associated pivot bolt (22 according to embodiment Fig. 1 to 1B). This can be done, for example, by electromechanical Act done. A purely mechanical solution is shown in FIGS. 5 to 8 indicated and will be explained below.

The actuating pin 34 is on its side facing away from the door frame 48 side provided with a tapered end face 68, the opposite tendency is to the inclination of the inlet inclined surface portion 54 of the Striker plate 40. It is thus inclined opposite to the usual Trap inclined surface 70 of the trap. This bevel is used solely to the Operating pin 34 when opening the door leaf 62 from the pin receiving opening 58 to push it out to sections 56 and 54 can slide along, eventually returning to its first position take.

FIG. 3 shows the above-mentioned position of the actuating pin 34 indented into the pin receiving opening 58.

Figure 4 shows a modification 40 'of the striking plate, wherein on the Infeed inclined surface portion 54 of the control surface opposite thereto inclined inner inclined surface portion 72 follows. The actuating pin 34 'can therefore, as shown, without bevel at the free end of the pencil be formed, so for example in the form of a straight circular cylinder.

Both embodiments have in common that the actuating pin 34 and 34 'without the usual case of falling inclined slope (Bevel 70 of the case 36) is formed, so that an unintentional Insertion of the actuating pin due to collision with any Item G (see Figure 2) with the main component of motion perpendicular to the direction of movement of the actuating pin 34 and 34 'in is essentially excluded.

The position detecting device 66 according to FIGS. 2 to 4 can, in particular with electromechanical actuation of the bolt, of a For example, inductively operating position sensor be formed with connected control electronics for controlling the servomotors of Bars.

A pure mechanical solution is simplified in FIGS. 5 to 8 shown. Components whose principal functions according to those in the Figures 1 to 4 are the same reference numerals, however Increasingly provided by the number 100. You can see it with 134 designated cylindrical actuating pin, the transverse Bearing pins 174 is mounted linearly movable in the central lock housing 112 (in horizontal direction parallel to the wing plane). The biasing spring 164 spans this first position shown in the outward direction in FIG before, in the one with the inner end of the actuating pin 134 rigid connected head 176 to a housing fixed stop 178th strikes.

The outer end of the actuating pin 134 is with the already described inclined end face 168 provided with inclination opposite to Trap inclined surface 170 of the case 136 indicated in FIGS. 5 and 6.

With the pivot bolts, not shown (corresponding to the pivot bars 22 without Tilt) is a drive rod 180 is moving coupled, which passes through the housing 160 in the vertical direction. Within the housing 160 is a locking member 182 with the drive rod 180 rigidly connected, which with a horizontally displaceable in the housing 160 Locking slide 184 cooperates. The gate valve 184 is between a blocking position shown in FIG. 5 and one in FIG. 7 shown release position movable back and forth, by means of a Doppelarmhebels 186. This is about a bearing pin 188 in the housing 160th rotatably mounted. A driving pin 190 at its lower in the figures End engages in a slot 192 of the locking slide 184, so that the Locking slide 184 against pivoting of the double-arm lever 186 clockwise from its blocking position according to Figure 5 in his Release position is moved according to Figure 7.

FIG. 5 shows a starting position which assumes the door lock arrangement, when the door has been opened properly. The drive rod 180 is then in its highest position, in which the coupled with her Swing bolt are engaged in the respective additional lock housing. In this position is the drive rod fixed locking member 182 in one Position above the locking slide 184, where this in his Locking position is located and doing with a locking lug 194 in a stepped recess 196 in the area of the lower drive rod far corner of the Locking member 182 engages. In this way, a downward movement of the Drive rod 180 blocks the drive rod 180 otherwise due would perform corresponding spring preload.

Now, if the door is closed, the actuating pin 134, as has already been explained in more detail with reference to Figures 2 to 4, from Striker inserted into the housing 160 until he is currently his in Figure 7 again dash-dotted lines indicated second position (innermost Position), then again to engage in the pin receiving opening extend the strike plate.

In this to-and-fro movement, a head 176 acts transversely to the headpiece Pin movement direction linearly mounted pin 198 with the upper end of the double-armed lever 186 together. The pin 198 is over a biasing spring 200 in the extended position shown in the figures biased. Its outer end is in the one shown in the figures Beveled manner (inclined surface 202), so that when moving out of the in Figure 5 illustrated starting position to the right of the upper end of the Doppelarmhebels 186 is pushed upwards momentarily, since the Double arm 186 abuts a stopper pin 204 fixed to the housing. This pin 204 thus prevents a pivoting movement of the double-armed lever 186 in the clockwise direction of FIG. 5.

After passing the pin 198 on the double arm 186 in this first Phase of the movement of the actuating pin 134, the pin 198 moves back so that it after the subsequent reversal of movement according to Figure 7 then the double arm 186 entrains and this against the Pivoted clockwise. This leads to a movement of the locking slide 184 to the right with the result that the locking lug 194 of Lock slide 184 the locking member 182 releases to move down. In The result will also be bewegungsverkoppel with the drive rod 180 Swing bolt for engaging in the respective strike plate from her swung out respective additional lock housing. This pivoting movement However, only when the actuating pin 134 in the associated pin receiving opening (58 in Figure 3) engages, i. at practically closed door.

In its lowest position according to Figure 8, the drive rod 180 by means of a in Figures 5 to 7 below indicated releasable locking device 206 held. This can also with the drive rod 180th motion-coupled pivot bolt not swung back without authorization become.

The locking device 206 includes a locking pin 208, which means Preload spring 210 is spring-biased to the left in Figures 5 to 8. As long as the drive rod 180 is not in its lowest position according to Figure 8 is located, the locking pin 208 is flat with its left end the inside of the continuously formed drive rod 180 at. In the lowermost drive rod position, however, the locking pin 208 in a associated Sperrstiftausnehmung 212 of the drive rod 180 engage. is this happen, the drive rod 180 is blocked in this way.

If the door is to be opened, the locking device 206 is released. This can for example be done by a with the nut of the Central lock connected pivot lever 214 an actuating rod 216 pushes upwards, which in turn has a pivot lever 218 in Pivoted clockwise. A nose 220 of the pivot lever 218, which in an associated recess 222 of the locking pin 208 takes this in Figure 8 to the right with. Thus, the locking pin moves out of the recess 212th

At the same time, the drive rod 180 via a mechanism, not shown moves upward until it reaches its uppermost position according to Figure 5. at This upward movement is currently the gate valve 184 from his shown in Figure 5 starting position to the right (against the force a biasing spring 224), wherein two corresponding inclined Inclined surfaces 226 and 228 at the free end of the locking member 182 and at the Locking nose 194 interact like a wedge. In some cases, one is enough only such oblique surface on one of the two parts to this Effect. After passing the locking member 182 on the locking lug 194 moves the gate valve 184, as mentioned, back to his Starting position in which the locking lug 194 locking in the Stufenausnehmung 196 of the locking member 182 engages and the locking member against a Downward movement secures.

In this upward movement, it is not necessary that the locking device 206 is kept in its release position, since the Locking pin 208 comes to rest on the inside of the drive rod 180.

As has been explained with reference to FIGS. 1, 1A and 1B, FIGS Swivel bolt advantageously in pairs in associated additional lock housing used and act with a two Schwenkriegeln common strike plate together. Here is the one pivot bolt of the pivot bolt pair is formed as a first pivot bolt, the automatically triggered by the actuating pin 34 when closing the door, in the strike plate 32 engages. The other pivot bolt 24, however, is disengaged with appropriate operation of the cylinder lock, with a Tightening bevel 30 ensures that the door leaf to the door frame or pressed against the door frame seals.

Overall, you get a door lock assembly, the with a simple construction and easy installation one high security guaranteed. If the door is closed or closed, so automatically puts at least one bolt in the associated strike plate one. An unauthorized opening after closing the door is not yet is separately locked by pressing the cylinder lock door at least severely handicapped. If the door is additionally activated by pressing the Locked cylinder lock, so results due to the self-suit one reliable sealing.
