Description

• zwei sich gegenüberliegenden Drückerhalbnüssen einer Drükkerbetätigungseinrichtung zur Betätigung einer Fallenbetätigungseinrichtung mit einer verstellbaren Falle und einer Riegel-Treibstangenbetätigungseinrichtung zum Verstellen einer Verriegelungseinheit und wenigstens einer zusätzlichen Schloßeinheit und einer Schließeinheit wenigstens zur Betätigung der Fallenbetätigungseinrichtung wenigstens teilweise in zwei unterschiedlichen Betätigungsebenen und
• einer Verstelleinheit, mit der die Betätigung in den beiden Betätigungsebenen wahlweise festzulegen ist.

The invention relates to a locking device with

• two opposing pusher half nuts a Becker actuation device for actuating a latch actuator with an adjustable latch and a bolt espagnolette device for adjusting a locking unit and at least one additional lock unit and a closing unit at least for actuating the latch actuator at least partially in two different levels of actuation and
• an adjustment with which the operation in the two levels of actuation is optional.

A locking device of the type mentioned is known and consists of a main lock and at least one additional lock, which is connected via a drive rod to the main lock. The main lock has a door latch, a door latch, a door lock and a door handle or an outside knob. Since the additional locks on the drive rod can be difficult to operate with the key of the door lock, this task is transmitted to the door handle. In the interior of the main lock are therefore separated from each other a Fallenbetätigungs- and a Riegelreibstangenbetätigungseinheit. These are separated and operated as needed by the door handle and the door lock in two levels of operation. Depending on the operating side of the door, they are arranged differently in position. In order to use one and the same main lock for every possible operating page, a pin with opposite grooves is provided, which couple the actuating rods in the region of the lock cylinder selectively for one of the operating levels.

The disadvantage is that all parts of the main lock must be duplicated and remain unused during coupling single in a plane in the operation of the castle. In addition, the non-positive connection is made when changing the operating levels at a location which is far away from the split handle nut as the actual center of operation of the castle. As a result, there is a risk that the operating rod is bent and thus the entire locking device is unusable.

From the DE 41 18 485 A1 as well as the DE 36 30 747 A1 is a door lock with displaceable by turning the trigger sliding rods and a handle associated with the two-piece nut for actuating a case and a driving rod connecting slide known. The operation of the lock takes place in two levels. One level passes through a nut part and a pusher mandrel axis. With respect to this nut part, it is that which serves to serve the trap back. The other operating plane is formed by the other nut part and the drive rod connection. By a profile cylinder, the case can be moved in an operating plane of the castle.

The disadvantage is that the operating pages of the lock are finally determined by these levels of actuation and this is only suitable for the operation of the specified page. Thus, separate locks are needed for doors to be opened from outside and inside as well as left and right sides.

Another espagnolette with two-part pusher is from the DE 19 511 871 A1 known.

From the EP-A 620 341 is a panic lock known whose actuation side is selectable. For this purpose, the lock on a two-pusher nuts, between which a trap-driver element is arranged. The disadvantage is that the respective handle half and the catch driving element are firmly screwed together. Thus, it is no longer possible to operate the pusher half independently of the trap driver element. Consequently, it is not possible to use the same pusher on the lock to control a second function besides the trap retraction. "

Ultimately, out of the DE 25 53 522 A1 a door lock with a latch, latch, nut and polygon for a door handle known. Here, however, the nut is only divided so that the case can also take over the function of the bolt with.

It therefore raises the task of further developing a locking device of the type mentioned so that a changeover of the adjustment of an operating level in the other is easily possible.

According to the invention this object is achieved by a locking device with the features of the claim.

The advantages achieved by the invention are, in particular, that the adjustment are assigned to the two pusher nuts as the center of operation of the lock device. The transmission of forces to operate the bolt espagnolette and the latch actuator is done by the respective handle half-nut directly and thus the shortest path. As a result, not only deformation of long transmission lever is avoided, but the trap actuator, the bolt espagnolette and the operation of the latch actuator of the clamping unit not double, but simply formed.

The Fallenmitnehmer cam disc can engage in a Mitnehmerausnehmung arranged behind the trap latch tail. As a result, there is a single coupling between the latch actuator and the two pusher nuts, which is designed centrally and thus advantageous for the transmission of force and the possibility of switching the adjustment.

This makes it possible to actuate the at least one-piece formed Fallenbetätigungsstange, which extends from the latch actuating device to the closing unit of a locking device of the clamping unit in both operating planes.

The adjustment is an adjusting pin which is set in a pin recess of the Fallenmitnehmer-cam each behind a Nußspitze one of the pusher nuts. In this case, the pin is pushed completely through the Stiftausnehmung so that the one Druckerhalbnuß against the Fallenmitnehmer cam is free to move, while the adjusting pin is set behind the Nußspitze the other pusher half. As a result, the Fallenmitnehmer cam and this pusher half an actuating unit.

The adjusting pin is designed as a dowel pin. The tensioning pin is a hollow pin which is to be pressed into the pin recess, overcoming the outwardly acting clamping forces of the hollow cylinder. Even when moving the clamping pin from one level of actuation to the other these clamping forces are overcome.

The dowel pin will be moved when adjusting from one level of actuation to the other by an adjustment slot introduced in the housing. Here, the adjustment slot in both opposite wall halves, ie the dekel and the bottom plate be introduced.

The Fallenmitnehmer cam may be formed of metal and / or plastic or hard plastic. Which material or material combination is used depends on the respective conditions of use.

A drive rod lock 100, 101, 102 is in Fig. 1 shown.

• eine Drückerbetätigungseinrichtung 1,
• eine Fallenbetätigungseinrichtung 2,
• eine Schließeinheit 4 und
• eine Riegel-Treibstangenbetätigungseinrichtung 9, die in
• einem Gehäuse 5 wenigstens teilweise in einer Betätigungsebene E1 und in einer Betätigungsebene E2 untergebracht sind.

Main components of the espagnolette are

• a pusher actuating device 1,
• a fall actuator 2,
• a closing unit 4 and
• a bolt espagnolette actuator 9, which in
• a housing 5 are at least partially accommodated in an operating plane E1 and in an operating plane E2.

Essential to the invention is that a two-part pusher nut, which consists of a pusher half 11 and a pusher 12, locally cooperate with an adjusting unit 14, 15, 31, 32 as parts of the pusher actuator 1.

As the Fig. 2 . 3 . 4a, 4b, 4c and 5 show is between the pusher half 11, which is located in the operating plane E1 and the pusher 12, which is located in the operating plane E2, a Fallenmitnehmer cam 13 rotatably disposed. The Fallenmitnehmer cam disc has a pin recess 14 in which a dowel pin 15 (see. Fig. 3 ) is pressed. In the pusher half nuts 11, 12 each have a Reückervierkantausnehmung 18, 19 is arranged, on one side of a driver pin 16, 17 and, in contrast, a Nußspitze 31, 32 is formed.

To trigger device 1 include two in the Pressing square recesses 18 or 19 square shafts (not shown). Both square shafts are decoupled from each other in the area of the catch cam disc 13. For mounting purposes, both are mutually rotatable connected by a pin in this area. At least one of the square shafts, a door handle is arranged.

The driving pin 16, 17 of the pusher half-nut 11, 12 is connected to a control unit 24 of the bolt-driving rod actuator 9. The control element 24 consists of a carrier plate slidably guided on a base plate 51 of the housing 5 with a spring receiving frame. To guide the control 5 5 pins are arranged between the bottom plate 51 and the cover plate of the housing, not shown above. The spring retainer frame carries coil springs 25 as shown in FIG Fig. 4c are shown. In the rest position of the two pusher half nuts 11, 12 are the coil springs 25 at both ends both on the respective pin and on abutment surfaces of the support plates or the window receiving frame, so that upon displacement of the support plate down the coil springs remains at the lower pin in station and compressed under elevation from the upper pin and vice versa. For the rotation angle limiting another, extending in the circumferential direction recess is disposed on the respective pusher half-nut 11, 12, which abuts in a pivot range end position on a pin 27 arranged in the bottom plate 51. This is another pin 28 opposite. In the control unit 24 engages a transmission lever 26 which is connected to a drive rod 8.

Below this thus formed latch-Treibstangenübertragungseihrichtung 9 is the closing unit 4. This consists of a latch 45, to which a bolt tail 43 connects. A lock cylinder 41 and a lock bit 42 form a locking device. With the lock bit 42, the end of a Fallenbetätigungsgestänges 43 is actuated that extends to the trap unit 2 and there before a Mitnehmerausnehmung 22, which is inserted into a latch tail 23 of a case 20 engages. At the end of the latch tail 23 presses the end of a spring 21 which is biased against a Längsseitenumfassungswand 54 of the housing. The longitudinal side wall 54 is opposite a faceplate 6, on which the drive rod 8 is guided. Through the faceplate 6, the case 20 projects through and the latch 45 is feasible.

The free end of the Fallenmitnehmer cam 13 projects into the Mitnehmerausnehmung 22 inside. This can consist of two opposing sheets which enclose the latch tail 23 between them and thus form a driving opening.

For installation of the espagnolette 100, 101, 102 in a door, the housing 5, which is enclosed by the bottom plate 51, the longitudinal side wall 54, the faceplate 6 and the narrow side walls 52, 53, closed with a cover plate, not shown. In the bottom plate 51 is how Fig. 4a and 5 show, an adjustment slot 33 introduced. A just such adjustment slot is introduced in the cover plate, not shown.

Beyond that, in the wings as well Fig. 6 shows additional locks 104 recessed with pivot bolt 106. The additional keys 104 can each be actuated via their drive rod 8. In Fig. 7 the additional locks 106 are provided with modified pivot bolt in the form of locking tongues. These are actuated via the espagnolette 101.

In Fig. 8 are formed on the drive rods 8 closing piston 116. The drive rods 8 are actuated by the espagnolette 102.

The operation of the espagnolette, as it results from the illustrated embodiment will be explained.

When slamming the door, the case 20 is automatically pushed back against the force of the spring 21, and automatically pushed into this against a strike plate when it arrives. To open the door of the pusher nuts 11, 12, the Fallenmitnehmer cam disc 13 must engage frictionally in the Mitnehmerausnehmung 22 and pull back on the latch tail 23, the case 20, as in Fig. 5 is shown.

The adjusting unit is adjusted so that only the presser 12, the Fallenmitnehmer cam 13 can be actuated. For this purpose, the clamping pin 15 has been pushed into the operating plane E2. With the help of the pusher half-nut 12 can thus both the latch actuator 2 and the latch-drive rod means 9 actuate and with the help of lying in the plane E1 pusher only the bolt espagnolette 9th

If, with the help of a pusher and an inserted square in the Reückervierkantausnehmung 19 the Pusher half-nut pivoted by 45 ° counterclockwise, the control 24 takes the lower end of the transmission lever upwards, with the result that the drive rod 8 is moved to its closed position. When the pusher half-nut 12 is released in this state, it returns to its original position under the action of the coil springs 25. With the closed position of the drive rod both the additional locks 104, ... and the latch 45 are brought into the closed position. Thereafter, the lock bit is actuated in the direction of the closure position by means of the lock cylinder and settles in the case actuating linkage 43, so that the door leaf is firmly closed.

With the help of the pusher half-nut 11 is in the plane E1 actuation of the bolt espagnolette in the same manner possible, wherein the cam 42 of the clamping unit 4 can be operated from this level.

Unlocking and opening the door thus closed is in the plane E2 so feasible that first operated by means of a key of the lock cylinder and the cam is moved back and thus the entire latch espagnolette actuator 9 is released. Subsequently, the pusher half 12 is moved clockwise and the control member 25 is pushed down so that the drive rod is simultaneously moved upwards. Here, both the bolt 45 and the pivot bolt 106 or bolt tongues of the additional locks 104 and the closing piston 116 are withdrawn.

Unlocking and unlocking the bolt espagnolette 9 is possible from the handle half 11 in the plane E1 in the same manner.

For retraction of the case 20, the following possibilities arise in this position of the espagnolette lock.

In the plane E2 retraction of the latch 20 via the handle half 12 by the wall pin 15 is preset. In this case, the pusher half nut is actuated counterclockwise so far back that the latch tail strikes against the longitudinal side surrounding wall 54 and the latch 20 is pulled behind the cuff rail 6. Retraction of the latch 20 in the plane E2 is also possible by operating the lock cylinder 41 by means of a key. Here, the cam 42 presses the latch actuating linkage 43 upwards and thus the latch 20 back.

Retraction of the case 20 by means of the pusher half-nut 11 is not possible since, as Fig. 2 and 4b shows, between the pusher half 12 and the Fallenmitnehmer cam 13 no frictional connection can be produced. Retraction of the latch 20 is, however, in the manner already described by means of the key on the lock cylinder and the lock bit 42 by the latch actuating linkage 43 given.

By setting the tension pin 15 in the operating plane E2, the espagnolette lock is provided for operation from the inside, ie from the housing side. The opposite operating plane E1, however, is provided for external operation. With the help of a screwdriver can be pushed over the adjustment slot 33 of the clamping pin 15 of the operating plane E2 in the operating plane E1, so that, as Fig. 5 shows, by the handle half 11 both the latch actuator and the bolt espagnolette actuator 9 can be operated and by the handle half nut only the bolt espagnolette 9th

Essential to the invention is that the operating side of the door can be freely choose by moving the clamping pin 15 in the operating plane E1 or the operating plane E2. This also takes into account whether the door is left or right opening. Of particular advantage is that the two levels of operation E1 and E2 are ultimately formed only by the split pusher. The latch actuating device 2 and the bolt-driving rod device 9 are formed so that they are associated with both levels, but are to be operated together only by one operating plane. This ensures that all parts of the espagnolette 100, 101, 102 regardless of whether the operating plane E1 or the operating plane E2 is selected with the dowel pin, are active parts and remain.
