Abstract

The locking system relates to doors with a main lock (2) and one or more back-up locks (3) linked by a drawbar (11). The drawbar is coupled to a door opening mechanism (35) provided with an electromechanical or electromagnetic drive. The closing device incorporates an energy store, e.g. a spring, which is compressed when the door is closed, and when released, operates the drawbar to unlatch the door.

Description

The invention relates to a locking device for a door, a window or the like, with a Main lock box, at least one additional lock box and at least one the additional lock box with the Main locking box connecting tie rod.

Such a locking device is such. B. from the EP 798 436 A2 known. This locking device has the main advantage that the door outside the Middle, d. H. at least in the area of a corner over the Latch latch held and can also be locked. One falls with this locking device equipped door to the castle, then the first Latch latches on the striking plate on the door frame side pushed back, allowing the door to be closed becomes. If the door is in the closed position, the The latch bolt is pushed out of the additional lock case and goes beyond its trap position in one Locking position. Because the latch in this Bolt position against unauthorized pushing back is secured, z. B. by inserting a flat Tool in the gap between the door and the door frame this additional bolt lock cannot be unlocked. A such a locked door offers a high resistance against Burglary.

However, it has been shown that doors of this type are indeed without can be opened manually, an automatic Open z. B. by means of an electromagnetically operated Elaborate conversion work or Additional equipment required. You would have so many Attach the electric opener to the door frame as there are latches are. This is not only expensive, but also cumbersome and affects the visual appearance of the door or the frame, since the electric opener corresponding Have recesses. As a rule, can with known Electric openers traps with a 10 mm trap exclusion or 15 mm are released. Fall with a bigger one Exclusion from z. B. 20 mm can, however, by means of such Electric openers cannot be released.

The invention is therefore based on the object Locking device of the type mentioned above train that door, window or the like can also be opened electrically.

This task is the locking device initially mentioned type solved according to the invention in that the pull rod is coupled to an opening device and the opening device an electrical, electromechanical or electromagnetic drive for the tie rod has.

The following description will only refer to referred to a door, the embodiments also equally good for windows or other lockable Wing can be used. The invention Locking device offers the main advantage that the door in its closed position over the Auxiliary lock boxes are locked and still electrical can be opened as the inputs in Opening direction is shifted. About this tie rod the latchbolts are moved from their bolt position to the Fall out into the open position, d. H. completely retracted into the lock box. This Latch latches no longer hinder the opening of the door.

In a preferred embodiment it is provided that the drive is an electrically operated Unlocking device for an energy store having. The door is in the closed Position, then the energy storage is charged. Will the Unlocking device operated electrically, then the Energy storage unlocked and the stored in it Energy released. This energy causes a shift the pull rod and thus a closing of the Latchbolts.

In a preferred embodiment, the Unlocking device with an electromagnet axially displaceable anchor formed. Will the Electromagnet energized, then the armature is z. B. pushed out or drawn into the magnet. Through this Relocation of the anchor becomes the unlocking device actuated and the energy released in the energy storage. In particular, the energy storage is from a spring to Example of a compression spring formed.

One embodiment provides that the Unlocking device by means of a pivotable stored latch a first slidably mounted Section of the energy storage engages behind and blocked. If the unlocking device is actuated and thereby the Swiveled latch, then this gives the first slidably mounted section of the energy store free, and unblocked. This section will then shifted by the preloaded spring. Because of this first slidably mounted section of the Energy storage is coupled with the pull rod, too moved and transferred to the open position, in which the latchbolts are drawn into the housing.

The energy store preferably has a second one slidably mounted section, which with a, at Closing the door, window or the like actuatable lever is coupled. About this second slidably mounted section is the energy storage charged by operating the lever when closing the door and thereby moved the second section and onto this Way the spring is biased. If the door is opened, then the second section is back in the Starting position shifted so that the spring again can be excited.

When the spring is released, the two move supported sections pushed apart by the spring. This has the main advantage that the spring force a shifting movement is already initiated, the can be transferred to the pull rod relatively easily.

The lever is preferably a toggle lever which allows exert relatively high forces on the compression spring.

The knee of the knee lever is above the level of the Door wing or window wing in front, so that when closing the door or window has the knee on the frame, comes into contact with a stop plate in particular and relocated when the door or window was closed further and thereby the knee lever is stretched. In this way becomes the energy store every time the door is closed excited to move the stored energy for it the pull rod in the open position. It therefore only needs a triggering moment to stored to release energy.

Another embodiment provides that the drive Is electric motor. Electric motors have the essential Advantage that no energies have to be stored and that transmit relatively high forces with electric motors can be. For this, the electric motor intervenes Gearbox on the drawbar. There are Small motors, possibly known with overheating protection, whose operating voltage is essentially the operating voltage of door intercom systems. Thus one additional power supply with house wiring superfluous. However, this also applies to the electromagnetic or electromechanical design.

The electric motor is preferred in both directions of rotation controllable. This will unlock the door the electric motor is controlled in one direction of rotation, whereby the pull rod is moved to the open position. The electric motor can now remain in this position remain until the door is closed again. It is however, it is also conceivable that the electric motor is only one short period of time, e.g. B. 2 to 3 seconds in this position persists and is then controlled via a control unit and again in the other direction of rotation and the Drawbar moved to the closed position. Is preferred the control unit can be changed so that between the two Operating modes there is a choice. In this way becomes a holding or not holding opening of the door created.

The electric motor by means of a pulse is preferred controllable or rotatable. This will also via the control unit, which allows only one Impulse to trigger required.

In one embodiment it is provided that the Main lock box with a connecting rod and a change is provided that the drive rod one Protruding rod level in the direction of the change Has a headline and that the headline at a Displacement of the drive rod in the opening direction with the Change interacts and takes it with them. In this way is at a relocation of the tie rod, which with the Main lock box connecting rod is coupled to the Case of the main lock box also in the Box housing retracted, so that for the case of Main lock box the conventional electric opener can be omitted.

Preferably, the projection is from one of the Tongue flared tongue formed. This lead attacks on a rivet of change. This configuration has the main advantage that almost the same components can be used in the main lock box or conventional main lock box with the invention Components can be equipped or converted.

In a preferred embodiment it is provided that the additional lock box one when closing the door, the Window or the like automatically via the Latch position in a latching position Has latchbolts.

a side view of the main lock box with the box lid removed, the bolt is closed and the latch is in the latch position.

The one shown in FIG. 1 and overall with 1 designated embodiment of a Locking device has a main lock box 2 and two additional lock boxes 3. The lock boxes 2 and 3 are attached to a lock cuff 4. Of the Main lock box 2 is with a box lid 5 closed and there are a follower 6, a Lock cylinder 7, a latch 8 and a bolt 9 recognizable. The trap 8 is in the trap position, so that it from a striking plate shown in Figure 3 33, which is located on the door frame, in the Main lock box 2 can be pushed in. The Additional lock boxes 3 are also with a latch provided which are designed as latch bolts 10. Also the latch bolts 10 are in their latch position and can thus from a striking plate 33 in the respective additional locking box 3 are pressed. Finally, a tie rod 11 can be seen, the Main lock box 2 with additional lock boxes 3 drives connected.

Figure 2 shows the additional lock box 3 without Box cover, ij which the latch bolt 10 in the direction the section line III - III is slidably mounted. This latch bolt 10 is in his extended position, d. H. in its latch position. Of the Latch bolt 10 has one in its longitudinal direction extending groove 12 open on one side (Figure 3). In this groove 12 there is a locking element 13, which about an adapter sleeve 14 pivotable in the groove 12 and thus in Latch bolt 10 is mounted. This locking element 13 is provided with a locking lug 15.

In the trap position (not shown), it grips behind Locking nose 15 the lock cuff 4 and prevents one further extension of the spring-loaded Latch bolt 10. This spring force is from a Trap extension spring 16 (Figure 2) applied to a Spring guide pin 17 is pushed on and one hand on the inner wall of the housing of the additional locking box 3, on the other hand supported on a latch extension lever 18. This latch extension lever 18 is in a bearing 19 pivoted. The one opposite the bearing 19 End of the latch extension lever 18 engages one Trigger nose 20 opposite end of the locking element 13 and pushes it under the power of Latch extension spring 16 in the extension direction. Since that Locking element 13 via the clamping sleeve 14 with the latch bolt 10 is connected, this is also in the extension direction crowded.

In Figure 3 it can be seen that the latch extension lever 18th attacks the locking element 13, the direction of the force of the latch extension lever 18, however, not by the Adapter sleeve 14 formed pivot bearing of the locking element 13 goes so that the latch extension lever 18 Swing moment counterclockwise on the Locking element 13 exercises. Because of this swing moment the locking lug 15 and the trigger lug 20 from the Groove 12 excavated.

With the door open (not shown) it is Latchbolt 10 in that shown in Figure 1 Trap position in which another extension from Behind the locking nose 15 behind the lock cuff 4th (not shown) is prevented.

When the door slams or closes, the Latch bolt 10 via the striking plate 33 (FIG. 3) in the Additional lock box inserted.

The door is in its closed position and in alignment the latch bolt 10 to the latch opening 21 in Strike plate 33 on the door frame side, is completely inserted latch bolt 10 via the latch extension lever 18 pushed out of the additional lock box 3. While this extension movement also becomes the locking element 13 counterclockwise around the Adapter sleeve 14 pivoted. The trigger nose 20 comes here with the edge of the trap opening 21 facing it Striking plate 33 in contact, whereby the locking element 13th against the pivoting moment in the groove 12 so far is inserted that the locking lug 15 on the lock cuff 4 can slide past. In this way, the latch bolt 10 released from its trap position and can in the Extend the bolt positions shown in Figures 2 and 3. In this latch position the latch bolt 10 is approximately 10 mm to 15 mm further from the additional locking box 3 extended than in the trap position according to FIG. 1.

As can be seen from FIG. 2, the trap tail 22 a projection 23. It can also be seen from FIG. that around a bearing pin 24 a latch lock lever 25th is pivotally mounted and via a locking lever spring 26, which is designed as a leg spring, against the Is spring-loaded in the clockwise direction. Located the latch 10 in the fully extended Location according to Figure 2 or 3, d. H. in the latch position, then a trap locking edge 27 engages behind the projection 23. It can be between the projection 23 and the Trap locking edge 27, as shown in Figure 2, a there is a short distance, but the Trap locking edge 27 in the displacement path of the projection 23.

If the latch bolt 10 is now to be operated using a tool or the like are inserted into the additional locking box, the projection 23 comes to rest against the trap barrier edge 27 and a further insertion is prevented. Of the Latch bolt 10 is thus in its locked position locked against insertion.

If a trap reset lever 28, the with one arm 29 at the free end of the tie rod 11 and with his other arm 30 on another projection 31 of the tail tail 22 abuts, pivots, engages one Nose 32 of the free end of the arm 30 on a link 34 the latch lock lever 25 and lifts it out of his Locking position in which the latch locking edge 27 engages the projection 23 so far that the Trap locking edge 27 from the displacement path of the projection 23 comes out. In addition, the arm 30 bears against the projection 31 and pulls when the latch return lever 28 is pivoted the latch bolt 10 in the additional lock box 3. Is the latch bolt 10 is completely retracted the box 3 the door can be opened. This retraction of the The latch bolt 10 can only be used with the pull rod 11 be effected.

To enable the door to be opened electrically, the Locking device 1, in particular the lock cuff 4th provided with an opening device 35, which is shown in FIG is shown. This opening device 35 has Housing 36 on which the housing of Additional lock box 3 corresponds. This housing 36 is by means of screws (not shown), which in corresponding receptacles 37 are screwed in with the Lock cuff 4 screwed. Inside the housing 36 there is a drive 38 by an electromagnet 39 with an axially displaceably mounted armature 40 is formed. If this electromagnet 39 Voltage is applied, then the anchor 40 from the Electromagnet 39 in the direction of its longitudinal axis pushed out. The armature 40 meets one around a bearing 41 pivotally mounted trigger lever 42. This trigger lever 42 has a locking lug 43 which has a shoulder 44 engages behind the first displaceably mounted section 45. The electromagnet 39 with armature 40 and release lever 42 form an unlocking device 46 for the first Section 45. This first section 45 is cup-shaped designed and takes one end of an as Energy storage 47 serving compression spring 48. At first Section 45 is also attached to a rivet 49, which is connected to the pull rod 11 (Figure 6). By a Relocation of the first section 45 can therefore Drawbar 11 are moved.

The other end of the compression spring 48 is also in one cup-shaped second section 50, which is also provided with a rivet 51. Are preferred both sections 45 and 50 are identical. That rivet 51 extends through the pull rod 11 via a longitudinal slot 52 and passes through the lock cuff 4 over another Longitudinal slot 53 and is one with a first leg 54 Knee lever 55 connected. The other leg 56 of the Knee lever 55 is pivotable on the lock cuff 4 fixed. In addition, the two legs 54 and 56 pivotally connected to each other and form a knee 57, which protrudes laterally beyond the lock cuff 4 and via which the toggle 55 in its extended position, the is shown in Figure 5, can be transferred. In 4, the compression spring 48 is in its untensioned Position shown. By inserting the knee lever 55, such as 5 shows the rivet 55 in the elongated hole 53 shifted upward and thereby the second section 50 in Shift upwards in the direction of arrow 58. The first Section 45 lies with its shoulder 44 on the latch 43 on and is held in this position.

If a voltage is applied to the electromagnet 39, then the armature 40 is extended and hits the release lever 42 and pivots against the direction of the Clockwise around the bearing 41. The detent 43 comes here disengaged from shoulder 44, causing the first Section 45 is released. The preloaded compression spring 48 moves the first section 45 in the direction of the arrow 59 upwards, whereby the tie rod 11 into the rivet 49 position shown in Figure 6 is taken. On this way the latch reset lever 28 becomes as above described, operated and the latch 10 is ins Housing 36 retracted.

After opening the door, the toggle 55 falls out of his in its extended position shown in FIG not (shown) angled position, whereby the second Section 50 in the position shown in Figure 4 is shifted. The compression spring 48 is completely relaxed. In addition, the pull rod 11 can go so far down be postponed until, as described above, the exclusion the latch bolt 10 from the locking lug 15, the Strike plate 33 is present, is stopped. Especially is with the door unlocked but still closed the compression spring 48 still slightly under tension, so that the toggle 55 of the compression spring 48 in the angled position is pushed. The knee becomes 57 in Direction to a not shown on the door frame attached stop plate pushed out, causing the door being pushed open.

Figure 7 shows a second embodiment of a Opening device 35, which consists of a two-part Injection molded plastic housing 60 is made. This housing 60 or the housing halves have Receiving openings for journal 61 or shafts from Gears 62 one designated 63 overall Reduction or translation gear. In addition, in Housing 60 an electric motor 64 mounted on a Bevel gear 65 with a bevel gear 66 one of the Gears 62 meshes. Finally, the housing 60 has one Storage 67 for a rack 68, one of which Bearing pin 69 protrudes. With this journal 69 is the Drawbar 11 (only shown schematically) can be coupled.

The transmission gear 63 can be operated via the electric motor 34 set in rotation and the rack 68 moved become. In this way there is a displacement of the tie rod 11 and unlocking the additional lock boxes 3 possible. The transmission gear 63 is self-locking, so that a automatic displacement of the tie rod 11 is not possible is. A suitable control unit causes Impulse of the electric motor 64 is rotated. In addition, the electric motor 64 can be controlled via the control unit after a particularly selectable period of time turned back and the rack in the starting position be moved. Another possibility provides that the reverse rotation of the electric motor 64 only by the Closing the door is initiated.

In the view of the Main lock box 2, the box cover 5 is removed, see above that the closing mechanism is recognizable. So z. B. the of the lock cylinder 7 actuated change 70, the a bolt 71 on a slide 72 an arm 73 a Control nut 74 attacks, recognizable. The slider 72 acts on a sliding stop 75 on one Drive rod 76 is attached. In this drive rod 76 is the tie rod 11 hangs at 77. The steering nut 74 has a further arm 78 which is attached to a trap foot 79 the case 8 is present.

If the lock cylinder 7, the change 70 and over the control nut 74 in the direction of Actuated clockwise, then the arm 78 and the Latch foot 79 latch 8 in the main lock case 2 moved in. However, this can also be done in that the Handle nut 6 by means of a handle, not shown, in Is operated in the clockwise direction, the Handle nut 6, the control nut 74 during its rotational movement takes along. In addition, when the lock cylinder is actuated 7 or the follower 6 of the slide 72 and this the Drive rod 76 displaced, which actuates the pull rod 11 becomes.

FIG. 8 also shows that the drive rod 76 has a protrusion 80 extending from one out of plane 81 the drive rod 76 exhibited tongue 82 is formed. In Direction of displacement (arrow 83) is to the projection 80 adjacent a rivet 84 which, as shown in Figure 8a, is attached to the switch 70. If the drive rod 76 in Moves in the direction of arrow 83, then the tongue 82 comes to Plant on the rivet 84 and takes the change 70 towards the Arrow 83 with, as described above, the Control nut washer 74 moved in the clockwise direction and thereby the latch 8 in the main lock box 2 is drawn in. In this way, the trap 8 by means of the opening device 35 according to the invention in the Box 2 withdrawn and thereby the door electrically be opened.

According to the invention there is also the possibility of Opening device by means of a wireless remote control, to control in particular via the control device, so that it's not wired impulse transmission absolutely necessary. The remote control can also be an advantage can be used to open the door from the outside. It is the remote controls for the opener of chewing doors are conceivable etc. with the remote control for a car in one Combine control element. As an information carrier can use infrared light, ultrasound, radio and the inductive Transmission according to the transponder principle can be used.
