A control element (10) with a control curve is arranged at the connecting rod. The lock nut includes an engagement unit, which is engaged at the control curve for linear displacement of the connecting rod in a longitudinal direction and for pulling the bolt by rotating the lock nut in an opening direction. The lock nut includes two latch parts, which are rotatable independently of one another.

Description

The invention relates to a door lock according to the preamble of claim 1.

A generic comparable door lock is through the EP 0 668 425 A1 known. The door lock described therein has an actuatable via a lock nut case and a latch which is so in operative connection with the lock nut that it is retractable together with the case. The lock nut engages a linearly displaceable push rod, which is connected via a guide slot with the bolt. The push rod is designed as a box-shaped hollow part and further includes a pin which is arranged between two opposite box walls. At this pin engages a nut pivot lever, whereby the push rod can be moved and the bolt can be retracted. The bolt is designed as a sliding latch, which can be moved transversely to a predetermined by the push rod longitudinal direction. In practice, it has been shown that this door lock for certain applications takes up relatively much space.

It is therefore an object of the invention to avoid the disadvantages of the known and in particular to provide a door lock of the type mentioned, which takes up little space. In particular, a slim and compact design should be possible, whereby the door lock can also be used in filigree door constructions. The door lock should be characterized by a high degree of security against manipulation and operational safety. Then it should be usable as a so-called panic lock, which must be able to be opened from a panic side without a key by mere operation of a door handle.

These objects are achieved according to the invention with a door lock having the features in claim 1. Characterized in that on the push rod, a control with at least one control cam is arranged (in particular fastened) and the lock nut corresponding engagement means which engage the linear displacement of the push rod in the longitudinal direction and for retracting the bolt by turning the lock nut in the opening direction, the control cam of the control, a lock can be created with a small footprint. In particular, the installation depth required for installation in doors can thus be significantly reduced. Another advantage of the inventive arrangement with control and engaging means is that it allows a simple way Einzeihen the bolt before a case that is retractable via the lock nut.

To increase the operational safety, it may be advantageous if the engaging means associated with the lock nut comprise at least one roller which is rotatably mounted on the lock nut, preferably via a ball bearing and particularly preferably via a deep groove ball bearing. The at least one roller is at least on actuation of the lock nut in an opening movement on the control cam of the control can be supported and along movable. This reduction of the frictional resistance creates a door lock which is easily common at least during the opening movement.

In one embodiment, the lock nut may have two independently rotatable nut parts, to each of which a door handle can be attached. The respective nut parts may, for example, each have a square for mounting door handles (or door handles). Such nut parts are the expert known for a long time. Preferably, between the two nut parts may be arranged around the same axis of rotation, rotatable with at least one of the nut parts and preferably both nut parts engageable via a coupling mechanism nut pivoting lever. In this case, the at least one roller can be mounted on the Nussschwenkhebel or rotatably mounted.

It can be advantageous if at least one guide roller and preferably two guide rollers are or are arranged on the control element, via which the push rod can be moved along a guide surface in a rolling manner for linear displacement in the longitudinal direction. The guide surface can be formed by a profile that covers the front side of the lock housing directly or indirectly. The profile may for example be a weld-on tab which is arranged on the inside of a housing end wall.

The push rod may be geared connected via a guide slot with the bolt. The guide slot can be relative to the direction of movement of the bolt so that the gearbox is self-locking when the bolt is extended, so that the bolt is not pressed. The self-locking can be achieved by a longitudinally extending locking portion in the guide slot in a simple manner. The bolt can thereby be pivotable (pivot bolt) or displaceable in one direction (sliding bolt). For example, the pivot bolt in a plan view may have approximately the shape of a circular sector. Of course, it is also conceivable that the pivotable latch may have a hook-shaped engaging member.

The lock nut can have fastening means, by way of which the nut pivoting lever can be connected to one of the nut parts to predetermine a panic function, preferably via a screw.

In this way it can be ensured that, if necessary, the door can be opened from the panic side without a key by mere actuation of the door handle.

Each Nussteil can be assigned to the Nussschwenkhebel a rotatably mounted entrainment, which is switchable for transmitting the pivotal movement of the respective Nußils by key operation or electromagnetically by a drive element from an idle position outside the range of rotation of the Nussteil associated driver in an engaged position within the rotational range of the driver.

The previously described gear for pulling the bolt may have a clutch lever which is geared connected or connectable on the one hand with a cylinder lock and / or with an electromagnet for a remote release and on a other side with at least one Nutschwenkhebel associated driver element geared connected or is connectable. As previously described, the driver element can be rotatably mounted on Nussschwenkhebel, where it can be switched between an idle position and an engaged position. Of course, other driver elements are conceivable, which are switchable between an idle position and an engagement position with respect to a driver of a nut part.

Furthermore, it may be advantageous if the clutch lever is movable so that the manual unlocking of the door lock by means of a key and turning the lock nut over a starting position to a stop, the one driver element for coupling the one Nußils from an idle position switchable into the engaged position is that when turning back the key from the stop to the starting position and removing the key from the cylinder lock, the one driver element for decoupling of a Nußteils preferably under the action of a spring bias from the engaged position is switched to the neutral position, that upon activation of the electromagnet for coupling the one Nußils by magnetic loading, for example, an angled segment, the one driver element the idle position is switchable into the engaged position and that upon deactivation of the electromagnet, the one driving element from the engaged position is switched to the neutral position. The respective switching operations can be caused by moving the clutch lever in the longitudinal direction. Further, by complete rotation of the lock nut by means of a key in the closing direction (opposite direction to Aufschliessrichtung) and optionally by preferably simultaneous rotation of the lock nut over a starting position addition, for example by moving the bar on an approximately arcuate guideway of the clutch lever such as by lifting in a transverse direction Be moved longitudinally, that the one driver element for coupling the one Nußils from an idle position is switched to a permanent engagement position. To deactivate this permanent coupling position, the permanent coupling position can be canceled when turning the lock bart in the opposite direction, for example by passing the bar past an attack member of the clutch lever. Such a coupling mechanism may also be advantageous on its own.

The clutch lever can be slidably mounted in the lock housing via slide bearings in the longitudinal direction. The clutch lever may be displaceable against the force of a spring element from a rest position into the engagement position in the longitudinal direction.

Furthermore, it may be advantageous if the coupling lever is formed by a single, preferably consisting of a sheet metal component. Thereby, the door lock construction can be simplified.

The bolt may be configured as a pivot bolt, which is mounted pivotably about an axis in a pivot housing. Swing bars have the advantage that a space-saving design is possible and a power-saving or smooth gear mechanism can be created.

In a further embodiment, the door lock may further comprise an actuatable via the lock nut case, which is in operative connection with the lock nut, that it is retractable via a gear together with the bolt. The gear can be designed such that the case is retractable only after partial or complete collection of the bolt. It is particularly advantageous if the transmission is configured such that first the bolt is fully retractable and after reaching the retracted end position of the bolt, the partially retracted case is completely retracted.

The lock nut and preferably thereof the nut pivot lever may have a securing element which engages in the closed position for preventing a displacement movement of the push rod in the longitudinal direction for creating an open position in a fuse arrangement corresponding to the securing element. The securing element can be a pin attached to the nut pivoting lever and the securing arrangement can be a recess arranged in the push rod, which forms a stop for the pin in the longitudinal direction.

FIG. 1 shows an overall view of a door with a designated 1 door lock according to the present invention. On at least one side of the door lock a door handle 19 is attached. On the side facing the castle of the door frame a strike plate 29 is arranged.

How out FIG. 2 shows the door lock 1 consists of a main lock 50 in which the cylinder lock 20 is arranged and two secondary locks 30 and 31. The main lock 50 and the secondary locks 30,31 are attached to a profile 14. In the somewhat simplified representation according to FIG. 2 is from the main lock 50 only a housing side wall recognizable, bolt and trap are not shown. In contrast, in FIG. 2 hook-shaped engagement members 33 and 34 of the auxiliary locks 30 and 31 can be seen, which protrude relative to the profile 14. Of course, it is also possible to dispense with auxiliary locks for certain applications. A door lock can thus consist only of the main lock described in more detail below.

Constructive features of the main lock 50 of the door lock are from the FIGS. 3 and 4 and in particular from the enlarged detail according to FIG. 5 recognizable. Based FIG. 3 First, the main components and components of the main lock 50 are named. The exact operation of the door lock is then based on a slightly different door lock according to a second embodiment (see. Figures 15a / b / c / d, Figure 16a / b / c / d, Figure 17a / b / c / d and FIG. 18a / b ) explained in detail.

FIG. 3 relates to a side view of the main lock 50, in which a side wall facing the viewer and further a support half of a push rod 5 has been removed. The main lock 50 has a lock nut 2, which can be rotated in the c direction by pressing a (not shown here) door handle via a square. About the lock nut 2, the latch 4 can be actuated. This configured as a pivot latch 4 has in plan view and side view according to FIG. 3 about the shape of a circular sector. 5 with the already mentioned push rod is referred to, with the lock nut 2 can be brought into engagement. On the push rod 5 is a control element 10. This control element 10 defines a control cam, on which one of the lock nut associated roller 12 is supported. The push rod 5 is linearly displaceable back and forth in a longitudinal direction designated x.

FIG. 3 shows the main lock after the door has been opened by pressing a door handle and the door handle has been released (cf. Fig. 24a showing a door lock in the same position). The latch 4 is completely retracted and remains in this position. The first also retracted case 3 is pressed by releasing the door handle by Federkraftbeaufschlagung back to the outside and is located in the in FIG. 3 recognizable extended position (rest position). When closing the door then the tapered case 3 would be pushed back by the strike plate against the force of the corresponding biasing spring in the direction e. Actuation of the door handle is not required because the trap can move independently of the lock nut. Approximately simultaneously to the case 3, the trigger pin 40 is pushed back against the force of the biasing spring in the direction f, whereby the Locking mechanism of the door lock is activated and the bolt automatically returns to the extended position.

The main lock 50 has for the linear displacement of the push rod 5 in the longitudinal direction x and for pulling the bolt 4 by turning the lock nut 2 in the opening direction rollers 12, which engage a control cam 11 of a control 10. The roles are - as above all with the following FIGS. 15a-d will be explained in detail, in an opening movement on the control cam 11 of the control supportable and along mobile. The push rod 5 is geared connected via a guide slot with the latch 4. The latch 4 is pivotally mounted about an axis 18. On the pivot bolt 4, a bolt 35 is further formed, which engages in the guide slot of the push rod 5. The configuration of the guide slot is from the following FIG. 6 removable and designated there with 17. For retracting the bolt 4, the transmission further has a clutch lever 9, which is on the one hand geared to the cylinder lock 20 and an electromagnet of an arrangement for remote release of the lock connectable and on the other hand gear with at least one Mitnehmerelelement the lock nut is connectable , The clutch lever 9 is slidably mounted in the lock housing via slide bearings in the longitudinal direction (the direction of displacement indicated by arrow h). With the arrows a and b further directions of movement of the two main components of the transmission are indicated.

The enlarged view according to FIG. 5 shows more details of the main lock 50. The door lock can be operated via a rotatably mounted locknut 2, in which from both sides in a known manner, a door handle can be inserted. The lock nut is in each case for each lock side in each a separately pivotable Nussteil divided (in Fig. 5 However, only Nußsteil 6 can be seen, cf. but subsequent Fig. 8 ). Each nut part can be biased by means of springs against the rotational movement of the lock nut. Between the two nut parts, a Nussschwenkhebel 8 is freely pivotally mounted. The nut pivot lever 8 can also be biased by means of a spring arrangement in the same direction as the two nut parts 6 and 7. On both sides of the Nutschwenkhebels 8 each a driver element is pivotally mounted on a hinge. The driver element 15 is in the position according to FIG. 5 in an engagement position with the nut part 6. The driver element 15 is here, as is apparent, in the range of rotation of a driver 23 of the nut part 6, if the nut part in the direction of arrow c would be moved.

The control element 10 is fastened via a screw connection 38 to the push rod 5 or to the support halves of the push rod (cf. Fig. 6 ). Furthermore, two axes 39 of guide rollers 13 can be seen. About these guide rollers, the push rod 8 for linear displacement in the longitudinal direction rolling along a guide surface movable. The control element 10 has one of the lock nut facing end side, which forms a flank for the roller 12. This flank defines a control cam 11 to which the roll is supported and movable along.

Then shows FIG. 5 Furthermore, that the clutch lever 9 in the longitudinal direction is displaced back and forth (the direction of displacement is indicated by an arrow h) and is slidably mounted in the housing via a slot 47 and another sliding bearing 49. About the spring element 22, which is designed as a helical tension spring, the clutch lever 9 in the in FIG. 5 held biased position shown.

FIG. 6 shows that the push rod 5 can be formed from flat profiles. The push rod 5 consists of two mutually opposite support halves. In FIG. 6 For the sake of simplicity, only one support half is shown. The two support halves are arranged at a distance from one another and connected to one another via bridge elements (not shown here). Between the support halves 49, the control 10 is arranged approximately centrally. In this flat profile, the guide slot 17 is arranged. The flat profile further has a bore, via which the control element 10 is fastened by means of a screw connection 38. In FIG. 6 as well as in particular FIG. 7 It can be clearly seen that the control element 10 has two guide rollers 13. The guide rollers are mounted via ball bearings and by means of the axes 39 rotatably in a one-piece base body 34. In the present embodiment, commercially available deep groove ball bearings are used as rollers.

The FIG. 8 shows the structure of the lock nut 2. The lock nut has, as already mentioned two independently rotatable nut parts 6.7, to each of which a door handle 19 can be attached. Between the two nut parts 6 and 7 of about the same axis of rotation R rotatable, with at least one of the nut parts 6.7 via a coupling mechanism engageable nut pivot lever 8 is arranged. Each Nussteil 6.7 is assigned a Mitnehmerelelement 15, 16, which is switchable for transmitting the pivotal movement of the respective Nußils from an idle position outside the rotational range of the driver 23 in an engaged position within the rotational range of the driver. The fully assembled lock nut 2 is designed such that at least one of these driver elements is biased by means of a biasing spring 36 such that it is outside the pivoting range of the associated driver 23 (idle position). Optionally, the operator can set the lock so that only one driver element in idle position and that the driver element of the opposite side (panic side) is in engagement position on one side of the door. In this case, it is ensured that the door can always be opened from the panic side in a panic situation. However, the lock can also be adjusted such that in the rest position both driver elements occupy the neutral position. The panic function is disabled in this case to some extent. The door opening for both sides via an access control by activating an electromagnet or by key operation to unlock the door lock. Evidently, an advantage of the present door lock is that it allows different modes of operation and is thus characterized by a wide range of applications.

The Nutschwenkhebel 8 is designed as a double lever and has a first lever arm 37 with the rollers 12 and a second lever arm, which is responsible for pulling the case 3. At the second lever arm, a pin 26 is then arranged, which causes a locking of the push rod 5 in the closed position. In the region of a free end of the lever arm 37 of the nut pivot lever 8, the rollers 12 are rotatably mounted. For rotatable mounting preferably ball bearings and more preferably deep groove ball bearings are used. In the present embodiment, a roller 12 is arranged on each side of the nut pivot lever. Of course, it is also possible to provide only one role.

As FIG. 9 shows, the pivot bolt 4 is formed of a single component. The bolt 4 consists of a body made of steel, for example, on the side of each two pins are formed. The one pin forms the axis 18 for pivoting the Bolt and also pin-like bolt 35 forms the engagement member for the guide slot of the push rod.

In FIGS. 10 to 12 the clutch lever 9 is shown. This is evidently formed from a single component made of a metal sheet (eg steel). The created by cutting and forming operations sheet metal part 9 has formed on a web 48 about fork-like arms. The extension of the web 48 forming arm has a free end 43 which abuts the creation of the engagement position on the corresponding driver element, whereby this can be pivoted. The designated angled segment 46 also forms a stop, but for the other driver element. On the other hand, a tooth 45 with an arcuate control track 64 can be seen, which is in operative connection with a beard of the cylinder lock for creating a permanent coupling position. With 66 is designated a flank, which serves as a stop for the beard for a single coupling (see the following Fig. 15a and 16a ). Next is in the FIGS. 10 to 12 an attack member 65 can be seen, which is in operative connection with the beard of the cylinder lock for deactivating the aforementioned permanent coupling position. For this purpose, the engagement member 65 has a wedge-shaped end on which the beard can be passed during the rotational movement during the unlocking of the lock. The angled segment 44 is in operative connection with the electromagnet. The slot 47 forms a guide for the limited displacement of the clutch lever 9. Furthermore, the clutch lever 9 has a recess 42 into which a bolt engages (but see the following Figures 16a-d and in particular FIG. 25a / b ). The recess has a longitudinally extending and a sloping section. The named bolt is in FIG. 10 indicated in the form of a dashed circle, wherein the designated 56 'circle the bolt with retracted latch and retracted Trap (cf. Fig. 25a ) and designated with 56 "circle the bolt in permanent coupling position (see. Fig. 25b ) corresponds.

The FIG. 13 shows a perspective view of an inventive door lock 1 with a main lock 50 and two auxiliary locks 30 and 31. This door lock is constructed almost similar to the previously described door lock. Except for a modified push rod (see in particular following Fig. 21 ) all components are identical to each other.

The main lock 50 according to the perspective view in FIG. 14 is in a closed position. In this closed position, both the latch 4 and the latch 3 are swung out or extended.

Out FIG. 14 It can be seen that in addition to the bolt 35 and the axis 18 for pivoting the bolt 4 in a guide channel 54 of the guide slot 17 is slidably mounted. This recess has a slotted portion 55 into which a bolt 35 of the bolt engages. At this gate section is followed by a slightly wider, in the longitudinal direction x extending channel section. At this designated 54 guide channel, the axis of rotation of the bolt 18 is limited in the longitudinal direction.

The push rod 5 further has the guide slot 51, which determines the retraction and extension movement of the case 3. In FIG. 14 is then an elongated recess 54 in the form of a longitudinal slot recognizable, which cooperates with the release bolt. If the release bolt 40 is pressed in the f direction, the lock is automatically set into the closed position by spring force application (ie, the pivot bolt 4 is extended).

The door lock 1 is arranged directly behind an approximately U-shaped profile 14, which forms a lock plate. In this lock plate and a coupling rod 28 is guided, which transmits the movement of the push rod at the top and bottom of the secondary locks. It may also have a push rod with a guide slot, wherein the hook-shaped latch 33 can be moved approximately the same as in the main lock.

In the FIGS. 15a-d is the approximately simultaneous retraction of pivot bolt 4 and 3 case when opening a previously closed door from the opposite side of the panic side shown. In FIG. 15a is both latch 4 and 3 in a fully swung or extended position. In this closed position, a pin 26 is received in a complementary recess 27 in the push rod 5. An undesirable movement, for example, in manipulations in an attempted break-in in the a direction is not possible. The recess 27 has a with respect to the direction a about U-shaped boundary, which prevents further movement of the push rod 5 by abutting the pin 26 (see in particular. FIG. 18a ). The respectively associated with the bolt 4 and the case 3 guide slots 17 and 51 are configured self-locking in this position.

In FIG. 15a is the driver element 15 in an idle position, which corresponds to a rest position due to the bias by corresponding spring element. Upon actuation of a nut part on the corresponding square (eg by holding down a door handle) it rotates against the force of a biasing spring idle without the Nutschwenkhebel 8 rotates. Because with a handle operation and the nut pivot lever 8 must be swiveled in the direction of arrow b. Thus brought latch 4 and case 3 in an open position can be, the driver element 15 must first be brought into an engaged position. This movement can be done either by key operation or by a controllable via an access control drive element. A cylinder lock 20 has a lock bit, which engages with a closing movement on the stop 66 and the clutch lever 9 moves in the direction h. In FIG. 15a is the beard of the cylinder lock simplified and designated 63. The direction of rotation in the key operation to unlock is indicated by the arrow m. When the beard 63 moves in the m-direction, it pushes the tooth 45 away, whereby the clutch lever is moved in the h-direction (one-time coupling). Like the detailed representation according to Figure 17a shows, must be pivoted in the direction k for making this engagement position, the driver element. This pivotal movement is effected by striking the clutch lever 9. The engagement of the driver element 15 can also be achieved electromagnetically. About an access control system not shown here, the solenoid 25 is activated in the presence of an access authorization, so that the clutch lever 9 is moved in the direction h. The effect on the driver element 15 is obviously the same as when turning the cylinder lock 20. The advantage of the electromagnetic actuation is that the lock is released for actuation immediately.

After a first rotation of the lock nut coupled with Nussschwenkhebel (driver element 14 in the engaged position) initially only the pivot bolt 4 is retracted in a first partial movement. The case 3 is still in the fully extended position after this first rotary movement. This position is in FIG. 15b shown. Only after another rotary motion can the trap be retracted in direction e. The Guide slot 17 has therefore in the gate section 55 has a relatively short straight section, so that evidently the transmission in this area can not be operated by pressing the bolt 4. Also associated with the case 3 scenery 51 has a similar, but longer trained straight section. By this arrangement of the guide slots, the transmission acts in one direction self-locking. As a result of the described dimensioning of the guide slot 51, a so-called anticipatory locking mechanism is created.

FIG. 15c shows the lock 50 after another rotation, in which the pivot bolt is already almost completely retracted. The case 3 is fully retracted only after complete retraction of the pivot bolt. The fully retracted case 3 and 4 bar shows the FIG. 15d , In the FIG. 15d shown position with fully retracted latch 4 and 3 case is, for example, in the case of an open door. If the door is then closed again, the transmission is activated in such a way that the lock is automatically closed by inserting the release bolt 40 in the f direction. For this purpose, the push rod 5 is supported on a spring in the region of its upper end, which pushes the push rod in the opposite direction to the opening direction (indicated by arrow -a) down, whereby the closed position according FIG. 14 is specified as the rest position. This ensures that after an opening operation, the lock is automatically closed again.

FIG. 19 shows a perspective view of an arrangement with a case 3. The case 3 is apparently with a longitudinally displaceable, by the spring 58 acted upon bolt 57 is in operative connection. The retraction direction is indicated by the arrow e.

The FIGS. 20a and 20d show a front view with a partial section of the release bolt 40. It can be seen that the release bolt 40 is in the closed position ( FIG. 20a ) in the region of the narrow portion of the slot 53 of a fixed to the push rod profile. In the in FIG. 20d shown open position, the release bolt 40 is in the region of the wider portion of the slot 53. Because of the spring bias of the trigger pin 40 is slightly pushed out. As a result, the slightly thicker lower region of the release bolt causes a locking in the opposite direction to the opening direction (indicated by arrow -a) (see also the following FIGS. 22 and 23 ). If the release bolt is now displaced inward, under the action of the spring force a displacement of the coupling rod 28 and thus also of the push rod in the closing direction takes place. By pushing inward the door lock is thus automatically triggered, the release bolt is finally in the wider portion of the elongated recess 53rd

Like from the FIGS. 22 and 23 shows, the bolt on two different thick bolt sections. These portions are indicated at 40 'and 40 ", the bolt portion 40' being feasible through the narrower portion of the corresponding longitudinal slot, while the bolt portion 40" is feasible only through the wider portion and not through the narrower portion of the longitudinal slot (see FIG. Fig. 20a / d ).

Like from the Figures 24a and 24b and 25a / b, 26a / b and 27a / b, the door lock can also be brought into a permanent coupling position. This position is in the Figures 24b, 25b and 26b shown. In order to reach this position, the door handle must have something in the -c direction (with a key unlocked door). Fig. 26a ) to be turned around. At the same time, the lock bit 63 has to be turned beyond an exit position further in the n direction (the pivoting movement of the bar is indicated by a dashed circle). The beard 63 moves off the curved control track and pushes - like FIG. 24b shows - the clutch lever away. As a result, the clutch lever 9 is raised, whereby the bolt 56 in the va in FIG. 25b shown permanent coupling position in the recess 42 passes. Such a positioned clutch lever 9 ensures that it presses in all positions of the transmission via the stop 43, the driver element 15 against the driver 23 ( Fig. 26b ). To deactivate the permanent coupling position only the door lock with the key must be unlocked. During this movement, the beard passes the engagement member 65 and pushes it away, whereby the clutch lever 9 returns to its original position.
