Description

The invention relates to a drive rod lock with a main lock and a secondary lock according to the preamble of claim 1.

A generic espagnolette is from the US 5,290,077 known. There, a drive rod is moved vertically. On the drive rod sits a pin, which is guided in a slanted slot of a trap. The slot wall continues on one end into a stop with an opposite escape space for the pin, so that the case can be moved back in front of the stop pin without espagnolette.

An espagnolette lock with a main lock and actuated by means of the main lock outgoing rods extending auxiliary bolts shows the EP 0 853 177 A2 , There, the additional bolt is designed as a rolling pin. The main lock is lockable as well as lockable. When the pressures are applied, an arm of the pusher nut engages the latch tail. Another arm of the handle nut pushes the drive rod upwards. For latch retraction by means of lock cylinder actuation, this lock has a change lever. This change lever acts on a butt edge of the drive rod.

From the DE 267184 is also a drive rod actuated additional lock is known in which the bolt can extend transversely when driving rod operation. A mechanism of this kind is also used by the GB 1 544 213 disclosed.

The DE 35 05 379 C1 describes a espagnolette lock with an additional latch. The espagnolette lock has a pusher that can retract a latch by means of a pusher arm. The head of the trap acts on a slope a espagnolette slide to also displace the drive rod for the purpose of retracting an additional latch in the strike-back operation. This lock also has a change lever which engages the latch tail by operating the lock cylinder. The retraction of the additional lock via a gear transmission.

A pivot bolt, which can be closed by driving rod control back and forth, is of the GB 2 309 996 described.

The DE 29 65 517 U1 shows a locking device with a main lock, which has latch and bolt. From the main lock comes out a drive rod to drive the bolt of an additional lock.

The invention has for its object to provide an espagnolette closure closing technically improved construction.

The problem is solved by the invention defined in claim 1.

The dependent claims represent advantageous developments of the invention.

It is inventively provided that the main lock is a gear lock with alternating operation, wherein the changeover drive via the espagnolette. It is with respect to the gear transmission to a reduction gear. This means that after closing the main lock bolt, the transmission operation can be continued as a result of the change drive and thereby successful espagnolette displacement. The change lever is dragged along also in the presser foot operation, wherein it acts on a shoulder of the drive rod with a collision edge, this shifts and thus connected to the lever of the auxiliary lock pivoted with the withdrawal of the local trap. This embodiment requires a freewheeling cylinder of the built-in lock in the main lock cylinder, since the displacement of the drive rod acts on the reduction gear on the drive sprocket, which in turn cooperates with the closing member of the lock cylinder. In this case, the abutting edge comes to a shoulder according to a pivoting of the change lever in an attack position. Furthermore, the invention provides that the change lever is designed as a slide. In the case of an alternating operation, an espagnolette connection piece carries along the change lever in the corresponding direction. The entrainment of the change lever with pusher operation, however, takes place via a cooperating with the pusher transmission lever. Finally, it is an advantageous feature of the invention is still to provide a drive rod connecting piece with clearance associated toothed segment, which meshes with the final gear of the reduction gear. Generates the clearance in a simple manner by a pin / slot connection. The length of the clearance corresponds to the displacement path of the drive rod connecting piece during the change operation. This embodiment makes it possible to dispense with a designed as a freewheel cylinder lock cylinder and to use a normally designed lock cylinder.

The numeral 1 denotes an elongated faceplate. In the central region of the same this carries a main lock 2. On both sides of the same is ever a secondary lock 3 of the same structure on the faceplate 1 set. The main lock 2 has a main latch 4 Further, the main latch 4 is retractable by means of a Drükkernuß 6. Furthermore, the main latch 4 can be withdrawn at change operation by means of an insertable into an opening 7 lock cylinder 8 by way of a change operation.

Each secondary lock 3 is coupled via a drive rod 9 with the main lock 2. By means of this, a case 10 and a supplementary latch 11 of the secondary lock 3 are controllable. With regard to the supplementary bolt 11, it is a pivot bolt which forms a hook 11 'at the end. It is such an arrangement made that the case 10 is assigned below the supplementary bolt 11 to the secondary lock 3.

The dash-dotted line closing member 12 transmits its rotational movement to a radially slotted ring gear 13 of a reduction gear 14. An intermediate 15 of the reduction gear 14 cooperates with a located on the upper edge of the main lock bolt 5 rack 16. The final wheel 17 of the reduction gear 14, however, is in meshing engagement with a vertically oriented rack portion 18 of a parallel to the face-plate rail 1 displaceable espagnolette 19. The two ends thereof are connected to the respective drive rods. 9

At the pusher 6 engages a nut 20 via a slider 20, which the pusher 6 in the in Fig. 4 stops stop limited position. Material uniformly goes from the pusher 6 on the latch tail 4 'attacking Fallenrückzugsarm 6' from. This is equipped with a driving shoulder 22, which in turn acting on an angled portion 23 of the presser 6 partially comprehensive transmission lever 24. This is mounted around a lock box-side studs 25 via a coupling pin 26 of the transmission lever 24 is connected to a trained as a slide change lever 27. The upper end 27 'extends in front of a driving projection 28 of the drive rod connection piece 19. The upper end 27''is forked designed, wherein the yoke 6 closer to the fork leg forms a transversely to the displacement direction of the drive rod connecting piece 19 forming abutting edge 29. This acts together with a shoulder 30 of a projection 31 of the drive rod connection piece 19. The fork slot 32 at the upper end 27 '' of the change lever 27 is wider than the projection 31st

A pressure spring which is supported on the latch tail 4 'serves as a latch spring 33, which loads the main latch 4 in the forward direction. Limited is the forward movement by a lock-box-side projection 34 in cooperation with the latch tail 4 '.

Each secondary lock 3 has a lock bottom 35 attached to the faceplate 1. In parallel position to this a lock cover 36 is held. Between the lock bottom 35 and lock cover 36, the corresponding Schlossgerichte extends. This includes a surface on the lock bottom 35 sliding espagnolette slide 37, which is coupled to the angled end 9 'of the drive rod 9. In the upper part of the drive rod connecting slide 35 carries a control projection 38 for cooperation with a control recess 39 of the supplementary bolt 11. This configured as a pivot bolt supplementary latch 11 superimposed in the upper part of the lock box to one of the faceplate 1 adjacent standing pin 40. In closed back latch position of the supplementary latch 39 occurs completely behind the front surface of the faceplate 1 back. In this projecting the hook 11 'in a passage opening 41 of the faceplate 1 inside.

The stored below the supplementary latch case 10 is composed of a case head 10 'and a latch tail 10''. The case head 10 'is positively guided in a Stulpöffnung 42. He formed at his the faceplate 1 superior end of a ramp 30, which cooperates with a door frame-side lock plate 44. At this 11 inlet openings and the trap 10, inlet openings 45, 46 are provided. To guide the inner end of the case 6 is on the latch tail 10 "in the direction of the lock cover 36 superior, uniform material guide pin 47 is provided, which engages in a transverse to the faceplate 1 transverse slot 48 of the lock cover 36, see, in particular Fig. 5 , The guide pin 47 is based on a transverse to the direction of displacement of the latch tail 10 '' extending guide rail 49, which in turn slides along the inner surface of the lock cover 36.

The latch 10 is gear-coupled to the drive rod 9 with a helical slot / tenon control. For this purpose, the latch tail forms on the espagnolette 37 facing broad surface rising in the direction of the faceplate 1 inclined slot 50 from. This runs approximately at an angle of 30 ° to the traversing direction. The Schloßkastenrückwand facing Schrägschlitzwandung 50 'is at the upper end in a stop 51 with opposite Ausweichraum 52 for a broad side of the espagnolette gate valve 37 outgoing pin 53 continues. Its diameter is slightly smaller than the width of the oblique slot 50. The stop 51 is formed by the fact that the latch tail 10 '' has a greater width in the cuff rail length than the case head 10 '. In the case function position according to Fig. 3 the pin 53 extends above the upper longitudinal edge of the case head 10 '. Therefore, an inward displacement of the latch 10 against the force of a latch spring 54 is possible without this movement is transmitted to the espagnolette gate 37 and thus to the drive rod 9. Then, the stop 51 is dimensioned so high that the upper edge of the latch tail 10 '' approximately tangent to the pin 53. The Fig. 3 illustrates that the stop 51 is an aligned extension of the slanted wall 50 '.

A two-armed angle lever 56 is mounted around a stud bolt 55 extending between the supplementary bolt 11 and the catch 10. Its short, approximately horizontally oriented lever arm 56 'extends above a cam 57 of the espagnolette slide 37 and cooperates with this. The long lever arm 56 '', however, points in the downward direction, traps the latch tail 10 '' and engages the transverse guide bar 49 of the latch tail 10 '' on.

The following mode of action occurs:

If a door equipped with the espagnolette lock according to the invention is closed, the traps 4, 6 initially yield. Thereafter, the main latch 4 enters an engagement opening 58 of the strike plate 44, while the traps 10 are immersed in the inlet openings 46. It is due to the case function position in front. From this, for example, a case 10 can be pushed back. However, this does not affect the other traps. When pushing back a case 10 of the connecting slide-side pin 53 passes through the escape space 52 of the case 10th

Starting from the position according to 3 and 4 can be operated by means of the lock cylinder 8 associated key the reduction gear 14 connected to a Vorschließ the main lock bolt 5 in the position shown in FIG. 1 and 7. Here, the final wheel 17 of the reduction gear 14 causes a downward displacement of the drive rod connection piece 19, wherein the projection 31 provided in this the fork slot 32 of the change lever 27 retracts. The drive rod 9 and the associated connecting rod connecting slide 37 of the secondary lock 3 are displaced in the process by means of the control projection 38. The supplementary bolt 11 is swung out into the rear grip position toward the strike plate 44. In this case, the driving in the downward direction pin 53 causes a feedforward control of the case 10 on the case function position addition to the position according to Fig. 6 , Then, the pin 53 extends at the lower end of the inclined slot 50.

The opening of the door thus requires an oppositely directed closing rotation of the key associated with an upward displacement of the drive rod connection piece 19, which transmits to the drive rods 9. The espagnolette slide 37 of the secondary lock 3 moves in the upward direction, and it will be the supplementary latch 11 pivoted back and the case 10 is first withdrawn in its Fallenfunktionsstellung. Upon continuation of the opening-closing rotation then applied to the cam 57 of the espagnolette gate valve 37, the short lever arm 56 'of the angle lever 56 and pivots it counterclockwise, the long lever arm 56''on the guide bar 49, the case 10 draws lock inwards. In this final phase of the opening operation of the driving projection 28 acts on the change lever 27 and displaces it in the upward direction, wherein the transmission lever 24 is pivoted and brings the main latch 4 out of engagement with the strike plate 44. The door is thus openable.

The only closed door can also be opened by means of a handle operation. The corresponding position is in 8 and 9 demonstrated. When trigger shift the Fallenrückzugsarm 6 'pulls the main latch 4 back. Further, the Fallenrückzugsarm 6 'moves over its driving shoulder 22 in cooperation with the bend 23, the transmission lever 24 in the clockwise direction. By the coupling pin 26 of the slider-like change lever 27 undergoes an upward movement with a superimposed pivoting, wherein its abutting edge 29 occurs against the shoulder 30 of the drive rod connecting piece 19 and displaced in the upward direction. In this case, the angle lever 56 is pivoted about the espagnolette gate 37 and its cam 57 which in turn retracts the case 10, which is also made possible by the escape space 52 of the case 10. Since the drive rod connecting piece 19 is displaced in this opening by pusher displacement and this transmits via the reduction gear 14 to the ring gear 13, the lock cylinder 8 is designed as a freewheeling cylinder.

According to the second embodiment, shown in FIGS 10 to 12 , like parts bear like reference numerals. Deviating from the first embodiment, the final wheel 17 of the reduction gear 14 now meshes not directly with the drive rod connection piece 19, but with a toothed segment 59 associated with the drive rod connection with clearance in the form of a short, in partial overlap to the drive rod connection piece 19 rack. To achieve the clearance the toothed segment 59 is provided with two parallel to the face plate 1 extending short longitudinal slots 60, in which pin projections 61 of the drive rod connection piece 19 dive. In the case trailing position, the pin protrusions 61 extend at the lower ends of the longitudinal slots 60.

This second embodiment allows the installation of a normally designed lock cylinder. The mode of operation corresponds to that of the first embodiment with the deviation that when locking the toothed segment 59 moves only to the clearance in the downward direction to then take the espagnolette connector 19 and the seated drive rods 9, so that the secondary locks 3 are also controlled in their locking position. Fig. 11 shows that the main lock bolt 5 is preconnected and the pin protrusions 51 are located at the upper end of the longitudinal slots 60. In the opening-closing rotation, first an upward displacement of the toothed segment 59 takes place around the clearance. Thereafter, the espagnolette connector is entrained and brought about this unlocking. In the final phase of the opening-closing rotation, the main latch 4 and the traps 10 of the secondary locks 3 are then withdrawn analogously to the first embodiment.

Fig. 12 illustrates the pusher operation for retracting the traps 4, 10 in non-locked latch members. In this displacement, the Treibstangenanschußstück 19 is slightly displaced over the abutting edge 29 in the upward direction as in the first embodiment. This movement also make the pin projections 61 of the drive rod connection piece 19 with. Due to the longitudinal slots 60 of the toothed segment 59, however, the toothed segment 59 stops, so that this handle operation does not transfer to the reduction gear. The ring gear 13 thus stops, which allows the use of the normally designed lock cylinder.
