On one end side, a skewed slot wall (50') continues into a thrust piece (51) with facing deflecting space (52) for the pin (53). The skewed slot belongs to the catch bolt, and the pin rests on the broad side of a connecting rod slide piece (37).

Description

The invention relates to an espagnolette lock a main lock and a secondary lock, preferably two side locks, the main lock and the Secondary lock each have a trap by one pre-closed trap function position in a closed Position both together with a drive rod displacement retractable into an open position as well as each one can be pushed back, whereby at least the case of the secondary lock with the Drive rod gear coupled is that in a Locking position displaced drive rod over the trap Trap functional position beyond.

An espagnolette lock of the type in question is known from DE 296 05 517 U1, the drive rod is divided into a first and a second drive rod, which can be moved from the specially designed main lock are. The first is inside the secondary lock Driving rod coupled with two tabs, one of which one via a tenon / arch slot connection with a toothed drive wheel cooperates, the latter in clamping engagement to the toothed lower edge of the trap stands. The other tab, on the other hand, works together a slide, which in turn on the drive wheel is articulated. This configuration allows the For example, when closing the door in the direction of the lock can be pressed without this affects the drive rods. That means that at closed door and in the trap function setting Fall pushing back one trap to none Pushing back the other trap results in the security value such espagnolette closures. The disadvantage, however, is the complex and thus too high Trap control leading to production costs.

The object of the invention is based on the object a generic drive rod closure of to provide an improved structure in terms of locking technology.

This task is first and foremost with one Espagnolette lock with the features of claim 1 solved, with the aim that the trap of Secondary lock with an oblique slot / pin control is geared to the drive rod, whereby an inclined slot wall on one end in a stop with opposite room for the Pin continues with the trap closing relocation.

As a result of such a configuration is a generic one Espagnolette lock of closing technically favorable Structure specified. It is not necessary that Control of the secondary lock with two connecting rods accomplish. Nevertheless, the trap can be removed from her Push back the trap function position without this has an effect on the drive rod. For example a main lock equipped with two secondary locks, so leads to their trap function position traps occurred pushing back the trap of a Secondary lock to no pushing back the others Fall. In a simple way, this is just through a correspondingly designed slanted slot / pin control realized which the latch of the secondary lock the connecting rod couples. In detail, this looks like that in the trap function position the pin on Height of the evasive space, which the stop is opposite the diagonal slot wall. Hereby is capable of being caught by a trap spring not to step forward on their trap function position. Pushing back the trap is allowed due to of the free space interacting with the pin. Is one with the drive rod closure designed according to the invention provided the door is closed, so are all Traps locked in their trap function position. When it is locked by Key actuation is via the with the drive rod coupled pins over the latch of the secondary lock pre-locked their trap function position. The Components for trap control are accordingly on Minimum reduced combined with a simple structure and cost-saving manufacturing. It is provided that the slant slot of the trap and the peg on the broad side of a connecting rod connecting slide sits on which in turn the one leading to the main castle Drive rod attacks. Furthermore, the Invention characterized in that the stop is in alignment Extension of the diagonal slot wall is. So that Case of the secondary lock from its latch function position both by lever and key-related Switching operation is retractable, stored in Additional lock a two-armed angle lever, the long one Lever arm attacks the trap and its short lever arm is acted upon by a cam of the drive rod. Experienced with every trigger and change operation the drive rod has a short stroke that is used to pivot the lever over the cam and thus the Withdraw trap. In order to achieve a stable Trap guide of the case of the secondary lock forms the Trap a guide pin that fits in one Cross slot of the lock case ceiling is guided. For It is planned to increase the security of the To assign a latch bolt adjacent to a lock latch, which together with the trap from the to the locked position displaced driven rod extends driven. The safety value is increased by the supplementary bar is a hook. An outgoing from this Hook engages behind in the locked position the locking engagement opening of a door frame side Striking plate. Furthermore, the invention provides that the main lock has a gear transmission lock Change operation is, with the change drive over the drive rod is shifted. It is about with regard to the gear transmission by a reduction gear. This means that after closing the Main lock bolt continued the transmission actuation can be accompanied by the change drive and thereby shifting drive rod. The change lever is also dragged when the follower is actuated, being a shoulder with a butt edge acted on the drive rod, this moves and so that the lever of the additional lock is also pivoted associated with withdrawing the trap there. This configuration requires a freewheel cylinder Lock cylinder built into the main lock, because the Displacement of the drive rod itself via the reduction gear affects the drive sprocket, which in turn cooperates with the locking member of the locking cylinder. According to this, the butt edge reaches one Swiveling the change lever into an attack position to the shoulder. Furthermore, the invention provides that the exchange lifter is designed as a slide is. When actuated alternately, a connecting rod connecting piece drags the change lever in the corresponding Direction with. Carrying the change lever with Lever actuation, on the other hand, is carried out with a Handle follower cooperating transmission lever. Finally there is an advantageous feature of the invention still in it, with a connecting rod connector To provide a tooth segment assigned to the clearance, which combs with the last gear of the reduction gear. The clearance is generated in a simple manner by a Pin / slot connection. The length of the passage corresponds to the displacement path of the connecting rod connecting piece when changing operation. This configuration allows it to be designed as a freewheel cylinder Lock cylinder to do without and a normal one designed lock cylinder.

With the number 1 is an elongated faceplate designated. This is entered in the middle area Main lock 2. On both sides of the same is a secondary lock 3 of the same structure on the faceplate 1. The main lock 2 has a main lock latch 4 and underneath a main lock bolt 5. Retractable is the main lock latch 4 by means of a press nut 6. Furthermore, the main lock latch 4 can be activated when changing by means of an installation opening 7 usable lock cylinder 8 by a change of actuation be withdrawn.

Each secondary lock 3 is connected to the drive rod 9 with the Main lock 2 coupled. By means of this are a trap 10 and a supplementary bolt 11 of the secondary lock 3 controllable. Regarding the supplementary bar 11 acts it is a swivel bolt, which has an end Hook 11 'forms. Such an arrangement has been made that the trap 10 below the supplementary bar 11 is assigned to the secondary lock 3.

The closing element 12 indicated by dash-dotted lines transmits its rotational movement on a radially slotted one Ring gear 13 of a reduction gear 14. An idler gear 15 of the reduction gear 14 cooperates with one on the upper edge of the main lock bolt 5 tooth rack 16. The last wheel 17 the reduction gear 14, however, is in meshing Engagement with a vertical rack section 18 one parallel to the faceplate 1 relocatable connecting rod connector 19. The two The ends of the same are connected to the respective drive rods 9.

On the follower 6 engages via a slide 20 Nut spring 21 on which the follower 6 in the in Fig. 4 stops limited position. Uniform material goes from the follower 6 to the latch tail 4 'attacking Latch retraction arm 6 '. This is with a take-along shoulder 22, which in turn to a bend 23 of the follower nut 6 partially comprehensive transmission lever 24 acts. It is mounted around a lock pin on the lock case side 25. Via a coupling pin 26 is the transmission lever 24 with a slide Change lever 27 connected. The lower end 27 'extends before a driving projection 28 of the connecting rod connecting piece 19. The top end 27 "is bifurcated designed, the closer to the follower 6 Fork leg a transverse to the direction of displacement of the Push rod connection piece 19 forming abutting edge 29 forms. This works together with a shoulder 30 a projection 31 of the connecting rod connecting piece 19. The fork slot 32 at the upper end 27 '' of the change lever 27 is wider than the projection 31.

A compression spring supported on the trap tail 4 ' serves as a latch spring 33, which the main lock latch 4th charged in the direction of advance. The advance movement is limited due to a projection on the lock case side 34 in cooperation with the trap tail 4 '.

Each secondary lock 3 has one on the faceplate 1 attached castle floor 35 on. In parallel to this is a castle ceiling 36 held. Between Castle floor 35 and castle ceiling 36 that extends corresponding lock fittings. This includes a sliding rod connecting slide sliding flat on the lock bottom 35 37, which with the angled End 9 'of the drive rod 9 is coupled. At the top Area carries the connecting rod connecting slide 35 a Control projection 38 for cooperation with a control recess 39 of the supplementary bar 11. This as Swivel bolt designed supplementary bolt 11 is stored in upper area of the lock case around one of the faceplate 1 adjacent stud 40. In closed The additional bolt 39 enters the bolt position completely behind the front surface of the faceplate 1 back. In this the hook 11 'protrudes into one Passage opening 41 of the faceplate 1 into it.

The trap 10 below the supplementary bar is composed of a trap head 10 'and one 10 '' trap tail. The trap head 10 'is form-fitting guided in a faceplate opening 42. He shapes on his the faceplate 1 protruding end a ramp 43, which with a striking plate on the door frame side 44 cooperates. On this are for the supplementary bar 11 and the trap 10 inlet openings 45, 46 provided. To guide the inner end of the trap 6 is on the 10 '' tail in the direction of the Lock cover 36 protruding, uniform material guide pin 47 provided that in a transverse to the faceplate 1 extending transverse slot 48 of the castle ceiling 36 intervenes, cf. in particular Fig. 5. The guide pin 47 assumes a transverse to the direction of displacement of the Trap tail 10 '' guide bar 49, which in turn along the inner surface of the castle ceiling 36 slides.

The trap 10 is with an oblique slot / pin control coupled to the drive rod 9. For this forms the trap tail on the connecting rod connecting slide 37 facing broad area one in Sloping slot increasing in the direction of the faceplate 1 50 off. This runs approximately at an angle of 30 ° to the trap shift direction. The back of the lock case facing oblique slot wall 50 'settles at the upper end in a stop 51 with an opposite Escape space 52 for a broadside of the connecting rod connecting slide 37 outgoing peg 53 continues. Its diameter is slightly less than the width of the Oblique slot 50. The stop 51 is formed by that the latch tail 10 '' in the faceplate longitudinal direction has a larger width than the trap head 10 '. 3 extends in the trap function position the pin 53 above the upper longitudinal edge the trap head it 10 '. Hence an inward-looking one Relocation of the trap 10 against the force of one Fall spring 54 possible without this movement on the Espagnolette connecting slide 37 and thus on the espagnolette 9 is transmitted. Then the stop 51 is like this tall that the top of the trap tail 10 '' tangentially affects the pin 53. 3 illustrates that the stop 51 is an aligned extension is the oblique slot wall 50 '.

To one between the supplementary bar 11 and Trap 10 extending stud 55 is a two-armed Angle lever 56 mounted. Its shorter, approximately horizontal aligned lever arm 56 'extends above a cam 57 of the connecting rod connecting slide 37 and cooperates with it. The long lever arm 56 '', on the other hand, points downwards, overhangs the Trap tail 10 '' and engages the guer progressive Guide bar 49 of the trap tail 10 ''.

The following mode of action occurs:

Will one with the espagnolette lock according to the invention equipped door closed, so the Fail 4, 6 initially. Then the main lock latch 4 in an engagement opening 58 of the striking plate 44 a, while the traps 10 into the entry openings Immerse 46. It is the trap function position in front. A trap 10 can be made from this, for example be pushed back. However, this does not affect the other traps out. When pushing back one Trap 10 traverses the pin on the connecting slide side 53 the escape space 52 of the trap 10.

Starting from the position shown in FIGS. 3 and 4 by means of the key associated with the locking cylinder 8 the reduction gear 14 operated are connected with locking the main lock bolt 5 in the position according to 1 and 7. This causes Last wheel 17 of the reduction gear 14 a downward shift of the connecting rod connector 19, wherein the projection 31 provided on this in the fork slot 32 of the change lever 27 retracts. Accompanying the drive rod 9 and the associated with it Espagnolette connecting slide 37 of the secondary lock 3. About the control projection 38 is the supplementary bar 11 in the rear grip position to the striking plate 44 swung out. The effect is in the downward direction moving spigots 53 a pilot control of the trap 10 the trap function position into the position 6. Then the pin 53 extends on lower end of the oblique slot 50.

Opening the door therefore requires an opposite directional locking rotation of the key connected with an upward displacement of the connecting rod connecting piece 19, which is on the drive rods 9 transmits. The connecting rod connecting slide 37 of the Sub-lock 3 moves upwards, and it the supplementary bar 11 is pivoted back and the trap 10 first in its trap function position withdrawn. When the opening-closing rotation continues then acts on the cam 57 of the connecting rod connecting slide 37 the short lever arm 56 'of the Angle lever 56 and pivots it counterclockwise, the long lever arm 56 '' over the Guide bar 49 pulls the latch 10 inside the lock. In this final phase of the opening operation is applied to the Driving projection 28 the shift lever 27 and relocated this in the upward direction, with the transmission lever 24 pivoted and the main lock latch 4 out of engagement brings with the striking plate 44. The door is now openable.

The only closed door can also be used Lever actuation can be opened. The corresponding Position is shown in Fig. 8 and 9. When the handle is shifted the latch return arm 6 'pulls the main lock latch 4 back. Furthermore, the latch retraction arm shifts 6 'via its take-along shoulder 22 in cooperation with the bend 23 the transmission lever 24 in the clockwise direction. Through the coupling pin 26, the slide-like change lever 27 an upward movement with a superimposed pivoting, its butt edge 29 against the shoulder 30 of the connecting rod connector 19 occurs and this shifted in the upward direction. This is done via the connecting rod connecting slide 37 and its cam 57, the angle lever 56 is pivoted which in turn withdraws the trap 10, which also made possible by the escape space 52 of the trap 10 is. Because with this opening by pushing the handle Espagnolette connector 19 is shifted and this itself on the ring gear via the reduction gear 14 13 transmits, the locking cylinder 8 is a freewheel cylinder designed.

According to the second embodiment, shown in FIGS 10 to 12, the same parts have the same reference numerals. Deviating from the first embodiment Now combs the last gear 17 of the reduction gear 14 not directly with the connecting rod connector 19, but with a connecting rod connector toothed section 59 in the form of a clearance a short, partially overlapping to the connecting rod connector 19 lying rack. To achieve of the free passage, the toothed segment 59 is parallel with two to the faceplate 1 running short longitudinal slots 60 provided, in which pin projections 61 of the connecting rod connecting piece 19 immerse. In the trap forward position the pin projections 61 extend at the lower ends of the longitudinal slots 60.

This second embodiment allows the installation of a normally designed locking cylinder. The mode of action corresponds to that of the first embodiment with the deviation that when locking the toothed segment 59th first drives down the free passage, then afterwards the connecting rod connector 19 and the take driving rods 9 sitting there, so that the Side locks 3 also in their locking position to be controlled. Fig. 11 shows that the main lock bolt 5 is locked and the pin projections 51 at the upper end of the longitudinal slots 60 are located. When opening the opening rotation occurs first an upward displacement of the toothed segment 59 around the Clearance. Then the connecting rod connector taken and brought about this unlocking. In the final phase of the opening closing rotation then the main lock latch 4 and the latches 10 the secondary locks 3 analogous to the first embodiment withdrawn.

Fig. 12 illustrates the pull-back operation the traps 4, 10 in the case of not pre-closed ones Bolt links. With this relocation, as with first embodiment, the connecting rod connecting piece 19 slightly over the abutting edge 29 in the upward direction shifted. The pin projections also make this movement 61 of the connecting rod connector 19 with. Because of the longitudinal slots 60 of the toothed segment 59 remain however, the toothed segment 59 are so that these Handle actuation not on the reduction gear transmits. The ring gear 13 thus remains what the use of the normally designed locking cylinder allows.
