Description

The invention relates to a rod lock for locking a door leaf to a door frame with at least one lock designed as a rotary tension lock and a rod which are coupled to one another via at least one rod coupling.

Rod locks are used in many areas of technology in order to lock doors in their closed position, ie to lock the movable door leaf in a form-fitting manner on the fixed door frame. In this context, the term "door" should be understood to mean all types of openings that can be closed by a movable closing element, for example also gates, hatches, flaps, etc.

In order to lock the movable door leaf to the door frame surrounding the door opening, which can be formed by the edge of the opening itself or by a separate part, the rod locks have at least one, but generally several locks. To actuate the locks, the rod locks usually have an actuation in the manner of a rotary or swivel handle, which is coupled to the rod of the rod lock via a rod coupling in such a way that its rotational movement is converted into an axial movement of the rod. The rod is coupled to at least one lock via a further rod coupling in such a way that the axial movements of the rod are used to actuate the lock and thus to pivot its locking element.

As a rule, locks with a locking element which is arranged pivotably about a locking axis and which can be pivoted between an open position and a closed position usually by approximately 90 ° are used.

In addition, rod locks are also known in which the locks are designed as turn-clamp locks.

In the case of such rotary clamping locks, the locking element is not only pivoted between its open and closed position, but also moved in the axial direction to generate a clamping movement. With this type of twist-and-turn locks, the two movements are usually separated from one another, and it is often the case that the locking element is initially pivoted in a first movement section. The locking element is transferred from its open position to its closed position and the door leaf is secured against opening. In a second movement section, the locking element then becomes axial moves and the door leaf is tensioned in the axial direction against a door seal provided between the door leaf and the door frame. Both the first and the second movement section are often 90 °.

A rod lock, the locks of which are designed as such twist-and-turn locks, is for example from the DE 20 2013 104 879 U1 known. In order to couple the turn-clamp locks to the respective rods, a rod coupling is provided on each lock in this rod lock, which is designed in the manner of a lock case having a gear with a drive pinion. Adjacent lock cases can each be connected to one another using comparatively short rods. With a corresponding number of lock cases and associated rods, a rod lock can also be constructed in this way with a larger number of locks designed as turn-clamp locks.

Although this type of rod lock has proven itself in the past, it leads to a comparatively complex structure in the case of rod locks with a larger number of locks. Another disadvantage of these rod locks is that the lock cases always have a certain amount of play due to the design, which can add up to an increased overall play, which may be problematic in practice, due to the connection of the individual lock cases in the manner of a series connection.

The object of the present invention is therefore to specify a rod lock which is characterized by a simple and reliable structure regardless of the number of existing locks.

This object is achieved with a locking rod of the type mentioned in that the coupling rod is constructed as a pivoting lever.

By designing the rod coupling as a pivot lever, a structurally simple construction of the rod lock can be achieved even with a large number of locks designed as turn-clamp locks. The design of the rod couplings as pivot levers results in a kind of rod coupling of several locks via a common rod with a structure that is both simple and reliable.

In this context, an advantageous embodiment provides that one lever end of the rod coupling is connected to the rod via a joint and the opposite lever end is non-rotatably connected to the lock. Due to the articulated connection of one end of the rod coupling to the rod, the rod can be pivoted by moving the rod axially. Due to the non-rotatable connection of the other end of the lever with the lock, the pivoting movement of the rod coupling can be transmitted to the lock and this can be actuated.

A structurally advantageous embodiment provides that the joint has a joint pin which is rotatably arranged within a joint eye. The joint eye can be designed as a through hole. The hinge eye can be arranged on the rod, which results in a simple construction of the rod. This can be particularly advantageous in situations in which the rod lock is to be adapted to different doors. In such situations, the rods must be exchanged according to the respective installation situation and replaced with rods of the appropriate length. The rods can be produced in a simple manner by bringing them to the appropriate length and providing them with the appropriate bores.

An embodiment advantageous in this context also provides that the hinge eye is designed as an elongated hole slidably accommodating the hinge pin. As a result, transverse movements of the rod resulting from the rod coupling can be prevented, so that the rod moves only along its axis, but not transversely to it, despite the rod coupling designed as a pivot lever. This can be used for a simplified guidance of the rod of the rod lock in its longitudinal direction.

A particularly advantageous embodiment also provides that an actuation for actuating the lock is coupled to the rod via a rod coupling.

A structurally advantageous embodiment provides that the rod coupling is also designed as a pivot lever. In this way, both the rod coupling via which the rod is coupled to the locks and the rod coupling via which the rod is coupled to the actuator can be designed as a common rod coupling. This results in a structurally particularly simple and reliable structure.

The rod coupling assigned to the at least one lock and / or the rod coupling assigned to the actuation advantageously form, together with the rod, a parallelogram linkage.

Another embodiment provides that the lock has a locking element which is designed to be rotatable about a locking axis and movable along the locking axis. The turn-clamp functionality of the lock can be generated via the locking element.

The rotary movement and the axial movement of the locking element are advantageously superimposed at least in sections. In this way, the locking can be actuated with a small actuation angle compared to a turn-clamp lock, in which these movements take place in separate movement sections.

A further advantageous embodiment provides in this context that the locking angle of the locking element corresponds to the pivoting angle of the rod coupling. If, for example, the locking element is pivoted by 90 ° between its open position and its locking position, the required clamping movement can also be achieved immediately by means of a pivot angle of the rod coupling, likewise by 90 °.

In this context it is advantageous if the pivot angle is less than 180 °, preferably less than 135 ° and even more preferably equal to 90 °. In this way, the locking can be established or released in a simple manner via the parallelogram linkage. Over-dead-center positions, such as those that could arise with a pivot angle of the rod coupling of 180 ° and more, are avoided.

Another advantageous embodiment provides that the locking element is designed as a locking tongue or as a roller tongue. A locking tongue is distinguished by its structurally simple, cost-effective structure. A roller tongue offers the advantage that it can increase the clamping movement of the lock in a simple manner. A conical roller can be provided for this purpose.

It is further proposed that the lock be a locking shaft rotatably and axially movably arranged in a locking housing having. The locking element can be firmly connected to the locking shaft at one end thereof.

Another embodiment provides that the lock has a guide track for converting the rotational movements of the locking shaft into an axial movement of the locking shaft. In this way, a pivoting movement applied to the lock can be converted into both a rotary movement and a clamping movement of the locking element via the rod coupling designed as a pivot lever. The guideway advantageously has sections with different gradients. In this way, the proportion of the resulting axial and / or tensioning movement of the locking element can be adjusted. For example, the axial movement can initially be kept small in a first movement section and then, as soon as the locking element has gripped behind the door frame, the axial movement can account for a larger proportion, so that only then does the clamping movement predominate.

Finally, a further embodiment provides that two guide tracks are provided on opposite sides of the locking shaft. In this way, a symmetrical arrangement can be achieved. There is no risk of tilting or the like of the shaft within the housing.

In order to also be able to unlock the rod lock from the inside of the closed door in emergency situations, it is further proposed that the rod lock have an emergency release.

In this context, with a view to simple handling, regardless of the number of locks provided, it is further proposed that the emergency release be designed such that the rod and the lock can be decoupled from the actuation via the emergency release can be actuated to unlock the door leaf. The emergency release has a double function. Via the emergency release, first of all, the rod with all of the locks coupled to the rod is decoupled from the actuation, the coupling between the rod and the locks being maintained. Secondly, the emergency release also serves to operate all locks and thus to unlock the door leaf. In this way, an easy-to-use emergency release can be provided regardless of the number of locks provided on a rod.

An advantageous embodiment provides that the emergency release has a decoupling device for decoupling the rod from the actuation. The rod can be mechanically decoupled from the rod in a simple manner via the decoupling device. After decoupling has taken place, the rod can be moved and the lock coupled to it can be actuated without this having any effect on the actuation.

In this context, it is structurally advantageous if the decoupling device has a decoupling element which can be transferred from a decoupling position to a decoupling position transversely to the direction of the rod. Structurally simple decoupling devices can be designed in which only a short transfer path of the decoupling element between the coupling position and the decoupling position is provided.

In this context, it is also advantageous if the decoupling element is pretensioned in the direction of its decoupling position and is secured via a securing element. By removing the securing element, a decoupling can take place automatically in this way. Alternatively, it would of course also be conceivable that the decoupling element in the other Direction, so in the direction of its coupling position is biased. In this case, it would be conceivable, for example, to carry out the decoupling manually, for example by means of a decoupling handle, knob or the like.

A structurally advantageous embodiment further provides that the decoupling element is designed as a spring bolt.

A further advantageous embodiment provides that the securing element for decoupling the coupling element can be moved along a decoupling path in the direction of the rod. By moving the securing element in the direction of the rod, the decoupling element pretensioned in a direction transverse to the rod can be released so that it can move automatically into its decoupling position. This results in a simple decoupling of the rod from the actuation.

In this context, in order to avoid a jerky decoupling, it is advantageous if the securing element has an unlocking bevel running at an incline relative to the rod. In this way, a faster or slower decoupling can be achieved according to the angle of incline of the unlocking slope.

A further advantageous embodiment provides that the emergency release has an emergency actuation via which the at least one lock can be actuated. The rod, which is still coupled to the locks, can be moved via the emergency actuation and the lock can be operated in this way.

In this context, it is of particular advantage if the emergency actuation is kinematically coupled to the rod. Moving the manual override also moves the rod in this way.

A further advantageous embodiment provides that the emergency actuation has a driving device via which the emergency actuation is coupled to the rod and can be moved along a free-running path with respect to the rod. The emergency actuation can be moved freely with respect to the rod along the freewheeling path. In this area, a movement of the emergency actuation does not lead to a transfer of the movement to the rod. Only at the end of the freewheeling path is the emergency actuation coupled to the rod and takes it with it via the corresponding driver.

The movements of the emergency actuation with respect to the rod are advantageously guided via an axial guide. This results in a defined movement of the emergency actuation relative to the rod along the freewheeling path.

With a view to advantageous handling, it is also proposed that the emergency actuation has a handle by means of which the emergency actuation can be actuated by hand. The handle can also be kept in a signal color for the operator and have an indication of the manner in which the handle is to be moved. This can be of particular advantage in emergency situations with only poor visibility, since the operator recognizes the handle, which is designed in a signal color, as such over longer distances and receives information about the way in which the emergency actuation is to be actuated.

In this context, an advantageous embodiment also provides that the freewheeling path is limited by at least one stop that can be moved relative to the rod and at least one stop that is fixed to the rod. As soon as the two stops come into contact with one another, the stop which is fixed to the rod is carried along by the stop that is movable with respect to the rod and the rod is moved for the purpose of emergency unlocking.

In this context, a structurally advantageous embodiment provides that the driver has an elongated hole, the ends of which form two movable stops that interact with a stop that is fixed to the rod. In this way, the bar can not only be unlocked in an emergency, but also moved against the direction of emergency unlocking.

A further embodiment provides that the stop, which is fixed to the rod, extends at least partially into the elongated hole, which results in a movement guided in the area of the driver.

A particularly user-friendly embodiment is characterized in that the emergency release is designed as a one-handed operation. Regardless of the number of existing locks, the emergency release can be gripped and operated with one hand. The operator can use the other hand for other purposes, for example to hold a flashlight or a tool.

Another embodiment provides that the decoupling device and the emergency actuation work together in such a way that when the emergency release is actuated, the decoupling device for decoupling the rod from the actuation and then the emergency actuation for actuating the lock is activated. In this way, both the decoupling and the actuation can be achieved in a single movement.

In order to achieve a tight closing of the door, the locks of the rod lock can be designed as turn-clamp locks. By pivoting a locking element of the lock, not only a form-fit locking, but also compression by moving the locking element axially can be achieved via the twist-clamp locks a door seal provided between the door leaf and the door frame. In the case of ventilation systems, climatic chambers or similar applications, this allows the door to be closed in a pressure-tight manner.

In this context, structural advantages are offered by an embodiment in which the locks, which are designed as twist-and-tension locks, are coupled to the rod of the lock bar via a rod coupling designed as a pivot lever. The result is a simple and reliable structure regardless of the number of existing locks.

By designing the rod coupling as a pivot lever, a structurally simple construction of the rod lock can be achieved even with a large number of locks designed as turn-clamp locks. The design of the rod couplings as pivot levers results in a kind of rod coupling of several locks via a common rod with a structure that is both simple and reliable.

In this context, an advantageous embodiment provides that one lever end of the rod coupling is connected to the rod via a joint and the opposite lever end is non-rotatably connected to the lock. Due to the articulated connection of one end of the rod coupling to the rod, the rod can be pivoted by moving the rod axially. Due to the non-rotatable connection of the other end of the lever with the lock, the pivoting movement of the rod coupling can be transmitted to the lock and this can be actuated.

A structurally advantageous embodiment provides that the joint has a joint pin which is rotatably arranged within a joint eye. The joint eye can be designed as a through hole. The joint eye can be arranged on the rod, resulting in a simple structure of the rod. This can be particularly advantageous in situations in which the rod lock is to be adapted to different doors. In such situations, the rods must be exchanged according to the respective installation situation and replaced with rods of the appropriate length. The rods can be produced in a simple manner by bringing them to the appropriate length and providing them with the appropriate bores.

An embodiment advantageous in this context also provides that the hinge eye is designed as an elongated hole slidably accommodating the hinge pin. As a result, transverse movements of the rod resulting from the rod coupling can be prevented, so that the rod moves only along its axis, but not transversely to it, despite the rod coupling designed as a pivot lever. This can be used for a simplified guidance of the rod of the rod lock in its longitudinal direction.

A particularly advantageous embodiment also provides that an actuation for actuating the lock is coupled to the rod via a rod coupling.

A structurally advantageous embodiment provides that the rod coupling is also designed as a pivot lever. In this way, both the rod coupling via which the rod is coupled to the locks and the rod coupling via which the rod is coupled to the actuator can be designed as a common rod coupling. This results in a structurally particularly simple and reliable structure.

Advantageously, the rod coupling assigned to the at least one lock and / or the rod coupling assigned to the actuation together with the rod form a parallelogram linkage.

Another embodiment provides that the lock has a locking element which is designed to be rotatable about a locking axis and movable along the locking axis. The turn-clamp functionality of the lock can be generated via the locking element.

The rotary movement and the axial movement of the locking element are advantageously superimposed at least in sections. In this way, the locking can be actuated with a small actuation angle compared to a turn-clamp lock, in which these movements take place in separate movement sections.

A further advantageous embodiment provides in this context that the locking angle of the locking element corresponds to the pivoting angle of the rod coupling. If, for example, the locking element is pivoted by 90 ° between its open position and its locking position, the required clamping movement can also be achieved immediately by means of a pivot angle of the rod coupling, likewise by 90 °.

In this context it is advantageous if the pivot angle is less than 180 °, preferably less than 135 ° and even more preferably equal to 90 °. In this way, the locking can be established or released in a simple manner via the parallelogram linkage. Above dead center positions, such as those that could arise with a pivot angle of the rod coupling of 180 ° and more, are avoided.

Another advantageous embodiment provides that the locking element is designed as a locking tongue or as a roller tongue. A locking tongue is distinguished by its structurally simple, cost-effective structure. A roller tongue offers the advantage that it can increase the clamping movement of the lock in a simple manner. A conical roller can be provided for this purpose.

It is further proposed that the lock has a locking shaft which is rotatably and axially movably arranged in a locking housing. The locking element can be firmly connected to the locking shaft at one end thereof.

Another embodiment provides that the lock has a guide track for converting the rotational movements of the locking shaft into an axial movement of the locking shaft. In this way, a pivoting movement applied to the lock can be converted into both a rotary movement and a clamping movement of the locking element via the rod coupling designed as a pivot lever. The guideway advantageously has sections with different gradients. In this way, the proportion of the resulting axial and / or tensioning movement of the locking element can be adjusted. For example, the axial movement can initially be kept small in a first movement section and then, as soon as the locking element has gripped behind the door frame, the axial movement can account for a larger proportion, so that only then does the clamping movement predominate.

Finally, a further embodiment provides that two guide tracks are provided on opposite sides of the locking shaft. In this way, a symmetrical arrangement can be achieved. There is no risk of tilting or the like of the shaft within the housing.

In the event that the rod lock is provided with two rods that can be moved in different directions, it can have a corner deflection. The movements of one rod can be converted into a movement of the other rod via the corner drive.

In this context, it is advantageous if the corner deflection has a flexible deflection element which is movably supported in a guide and can be connected to the rods via assembly elements.

Furthermore, it can be advantageous in this context if the assembly elements each have at least two optionally usable assembly points for connection to the rods. Depending on the type of movement of the respective rod, one or the other mounting points can be used. The result is a flexible system that can be used with different rod locks.

In this context, an advantageous embodiment provides that at least one of the mounting points is designed in such a way that a rotational degree of freedom of the rod is maintained. With such a mounting point, the rod can be mounted in an articulated manner so that the rod can be pivoted following the movements of the mounting element.

From a structural point of view, it is advantageous in this context if the assembly point is designed as a hinge eye. A bolt can engage in the assembly point to form an articulated connection.

A further advantageous embodiment provides that at least one of the mounting points is designed in such a way that a translational degree of freedom the rod is preserved. In this way, it is possible for the rod to be fastened in the area of the assembly point so that it can also be moved in a translatory manner to a certain extent. In addition, a rotational degree of freedom can also be retained.

In this context, an embodiment is advantageous in which the mounting point is designed as an elongated hole. A bolt can be accommodated in a translationally movable manner within the elongated hole. Depending on the shape of the bolt, it can also be rotatable.

A particularly advantageous embodiment provides that the mounting element has at least three mounting points, of which two mounting points are of the same type and the third mounting point is configured differently, the different mounting point being arranged between the similar mounting points. In this way, the corner drive can be used in different mounting positions on the door and optionally one of the different mounting points can be used.

A further advantageous embodiment provides that the assembly elements have an assembly tab having the assembly points and a guide area for guiding the assembly elements in the guide. The guide area can be guided in the guide in the manner of a rail guide. The guide can have a first guide area for guiding the deflecting element and a second guide area for guiding the guide area. The second guide area for guiding the guide area can be shorter than the continuously formed guide area for guiding the deflecting element.

Another advantageous embodiment provides that the guide is arranged in a housing composed of two housing halves. There are assembly and manufacturing advantages. The deflection element and the mounting elements can first be inserted into one housing half and then the second housing half can be placed onto the first housing half in the manner of a cover, thereby forming the housing.

In this context, it is advantageous if the mounting tabs are arranged offset relative to the parting plane between the housing halves of the housing. For example, the offset of the mounting tabs with respect to the parting plane of the housing halves can correspond to half the thickness of the rod fastened there. In this way, the rod center plane is aligned parallel to the parting plane of the housing.

A further embodiment provides that the mounting tabs are arranged at least partially outside the housing and the guide area is arranged inside the housing.

In the event that the rod lock is provided with two rods that can be moved in different directions, it can have a corner deflection. The movements of one rod can be converted into a movement of the other rod via the corner drive.

In this context, it is advantageous if the corner deflection has a flexible deflection element which is movably supported in a guide and can be connected to the rods via assembly elements.

Furthermore, it can be advantageous in this context if the assembly elements each have at least two optionally usable assembly points for connection to the rods. Depending on the type of movement of the respective rod, one or the other mounting points can be used. The result is a flexible system that can be used with different rod locks.

In this context, an advantageous embodiment provides that at least one of the mounting points is designed in such a way that a rotational degree of freedom of the rod is maintained. With such a mounting point, the rod can be mounted in an articulated manner so that the rod can be pivoted following the movements of the mounting element.

From a structural point of view, it is advantageous in this context if the assembly point is designed as a hinge eye. A bolt can engage in the assembly point to form an articulated connection.

Another advantageous embodiment provides that at least one of the mounting points is designed such that a translational degree of freedom of the rod is maintained. In this way, it is possible for the rod to be fastened in the area of the assembly point so that it can also be moved in a translatory manner to a certain extent. In addition, a rotational degree of freedom can also be retained.

In this context, an embodiment is advantageous in which the mounting point is designed as an elongated hole. A bolt can be accommodated in a translationally movable manner within the elongated hole. Depending on the shape of the bolt, it can also be rotatable.

A particularly advantageous embodiment provides that the mounting element has at least three mounting points, of which two mounting points are of the same type and the third mounting point is configured differently, the different mounting point being arranged between the similar mounting points. In this way, the corner drive can be used in different mounting positions on the door and optionally one of the different mounting points can be used.

A further advantageous embodiment provides that the assembly elements have an assembly tab having the assembly points and a guide area for guiding the assembly elements in the guide. The guide area can be guided in the guide in the manner of a rail guide. The guide can have a first guide area for guiding the deflecting element and a second guide area for guiding the guide area. The second guide area for guiding the guide area can be shorter than the continuously formed guide area for guiding the deflecting element.

Another advantageous embodiment provides that the guide is arranged in a housing composed of two housing halves. There are assembly and manufacturing advantages. The deflecting element and the mounting elements can first be inserted into one housing half and then the second housing half can be placed on the first housing half in the manner of a cover, thereby forming the housing.

In this context, it is advantageous if the mounting tabs are arranged offset relative to the parting plane between the housing halves of the housing. For example, the offset of the mounting tabs with respect to the parting plane of the housing halves can correspond to half the thickness of the rod fastened there. In this way, the rod center plane is aligned parallel to the parting plane of the housing.

A further embodiment provides that the mounting tabs are arranged at least partially outside the housing and the guide area inside the housing.

To achieve the above object, further a door with a locking rod having one or more of the previously described Features suggested. The advantages already explained in connection with the rod lock result.

The Fig. 1a) to 1e ) show excerpts of doors 100 with a door leaf 101 arranged pivotably with respect to a stationary door frame 102. The door 100 can be a conventional door, for example in the manner of a door accessible by a person, or a larger door, for example in the form of a gate, or a smaller door, for example in the form of a hatch, a flap or the like. In the Fig. 1a) to 1e ) the closed position of the door 100 is shown, in which the door leaf 101 is locked to the door frame 102.

To lock the door leaf 101 to the door frame 102, a rod lock 1 is provided, which will be discussed in detail below. From the rod lock 1 is in the Fig. 1a) to 1e ) only recognizable actuation 2 accessible from outside the door, via which the lock between the door leaf 101 and the door frame 102 can be established or released.

According to the configuration in Fig. 1a ) the actuation 2 can be an actuation 2 interacting with a tool, for example a square, a triangle or a similar element. As shown in Figure 1b ) the actuation 2 can also be a handle, which has the advantage that no additional tool is required to actuate the actuation 2. The handle can be designed to be lockable via a lock cylinder. In addition to this simple design of a handle, for example, according to the illustrations in Fig. 1c) and 1d ) The use of swivel handles as actuation 2 is also conceivable, which are initially pivoted with respect to the plane of the door leaf 101 and then rotated in a next step. Again, according to Figure 1c ) Lock cylinders or other access control systems, such as an in Fig. 1d ) the illustrated fingerprint reader, transponder, card reader or similar systems may be provided. Moreover, the use of lever handles is also in accordance with Fig. 1e ) conceivable as actuation 2, which can be gripped and rotated to actuate the actuation 2. The present rod lock 1 can, however, be used for all types of actuations 2 regardless of the configuration of the actuation 2, which is why it can also be used other than that in FIG Fig. 1a) to 1e ) is possible.

In the Fig. 2a) to 2c ) as Fig. 3a ) to c) details of two rod locks 1 can be seen from the inside of the door.

The rod lock 1 is arranged on the inside of the door leaf 101 of the door 100 and extends parallel to an edge of the door leaf 101. The actuator 2 is arranged on the opposite outside of the door leaf 101 and in the configuration according to FIGS Fig. 2a) to 2c ) as a handle and in the design in the Fig. 3a) to 3c ) designed as a lever handle. The actuation 2 of the rod lock 1 is kinematically coupled to two locks 3 via a rod 4. A rotary movement of the actuation 2 is converted into a movement of the rod 4. The movement of the rod 4 is converted into a movement of the locking elements 3.1 of the lock 3 in order to actuate the locks 3. In the design according to Fig. 2a) to 2c ) are the locking elements 3.1 as locking tongues and in the design in the Fig. 3a) to 3c ) designed as roller tongues.

The Fig. 2 and 3 each show rod locks 1 with two locks 3, one lock 3 being arranged above the actuation 2 and one lock 3 below the actuation 2. However, rod locks 1 with more than two locks 3 are also possible in order to provide, for example, a three-point, four-point, five-point or even more locking point locking of the door leaf 101 on the door frame 102. According to the representations in the Fig. 13ff . a locking point can be arranged on the top and / or bottom of the door leaf 101, which can also be actuated via a corner deflection 30 via the actuation 2.

In the following, the coupling of the rod 4 with the locks 3 and the actuation 2 will first be discussed in detail, before further essential aspects of the rod lock 1 and in particular details of the locks 3, the emergency release 5 and the corner drive 30 will be discussed.

In the area of the actuation 2, the rod 4 is coupled to the actuation 2 of the rod lock 1 via a rod coupling 8. The rod coupling 8 is designed in the manner of a pivot lever extending between the actuation 2 and the rod 4, cf. also Fig. 8 . Via the rod coupling 8, a rotary movement of the actuation 2 about its actuation axis B is converted into an axial movement of the rod 4, the rod 4 in the embodiment according to FIGS Fig. 2 and 3 also moved a little to the side. One end of the coupling element 8 is connected non-rotatably to the actuation 2 arranged laterally next to the rod 4. The coupling element 8 follows the rotary movements of the actuation 2. When the actuation 2 is rotated, the coupling element 8 begins to pivot in the manner of a pivot lever. The other end of the coupling element 8 is hinged to the rod 4, so that the pivoting movements of the coupling element 8 are converted into an axial movement of the rod 4 in its longitudinal direction and a transverse movement. The transverse movement of the rod 4 is smaller in terms of amount than the axial movement.

The locks 3 are also coupled to the rod 4 via a rod coupling 9. The rod coupling 9 is designed in the manner of a pivot lever which extends between the rod 4 and a lock 3 and whose pivoting movements serve to actuate the lock 3. The details of the rod coupling 9 will be discussed in greater detail below.

The rod coupling 8 provided in the area of the actuation 2 forms, together with the rod couplings 9 and the rod 4 provided in the area of the locks 3, a parallelogram linkage 10. The actuation 2 is structurally simple and reliable via the parallelogram linkage 10 with the two locks 3 coupled. On the parallelogram linkage 10, in addition to the Fig. 2 and 3 A total of two locks 3 shown, further locks 3 are connected in order to obtain a rod lock 1 with more than two locking points, as is the case in particular in the case of large door leaves 101 and high demands on the compression of an between the door leaf 101 and the door frame 102 arranged seal can be advantageous.

The rod 4 is designed as a flat rod and is arranged parallel to the plane of the door leaf 101. The rod 4 and / or the rod couplings 8, 9 can be made from a metal strip.

The movements of the rod 4 designed as a flat rod are guided by rod guides 4.1. The rod guides 4.1 are arranged on the inside of the door leaf 101 and designed in such a way that they also allow the transverse movements of the rod 4 resulting from the parallelogram linkage 10, cf. Fig. 2 and 3 . The rod guides 4.1 therefore have a guide area 4.2 receiving the rod 4, which is wider than the rod 4 by the amount of the transverse movement, cf. Figure 2c ). In this way, the movements of the rod 4 are guided in the guides 4.1 both in the axial and in the transverse direction.

As the representations of the rod lock 1 in Fig. 2 and 3 This can be further recognized, the rod lock 1 has an emergency release 5, via which the door leaf 101 can be unlocked in an emergency situation by a locked person in a simple manner regardless of the number of existing locks 3 from the door frame 102. This is also discussed below, in particular with reference to the representations in FIGS Figures 8 to 12 will be discussed in more detail.

The Figures 4 to 6 show two versions of a rod lock 1 in different positions of a lock 3. A) is a first embodiment of the rod lock 1, which is essentially the same as that previously based on the illustration in Fig. 2 corresponds to the embodiment described, and with b) each designates a second embodiment of the rod lock 1. With c) lateral views of the rod locks 1 are referred to, which do not differ for the two versions.

As shown in the Fig. 4a) and 4b ) allow this to be recognized first, the rod locks 1 have a rod 4 designed as a flat rod. To transmit the movement of the rods 4 to the locks 3, a rod coupling 9 is provided in each case. The rod coupling 9 is designed as a pivot lever and is assigned to a lock 3 in each case.

The rod coupling 9 is connected in an articulated manner to the rod 4 in the area of its one lever end 9.1 via a joint 20, cf. especially Fig. 5a) and 5b ). The joint 20 consists of a joint pin 20.1 which is articulated within a joint eye 20.2. The other lever end 9.2 of the rod coupling 9 is coupled to the lock 3 in such a way that the pivoting movements of the rod coupling 9 are converted into a corresponding rotary movement of the locking element 3.1 about its locking axis V.

The joint eye 20.2 is formed by a through-hole arranged on the rod 4, whereby the rod 4 has a simple structure. Alternatively, the hinge pin 20.1 could also be arranged on the rod 4 and connected to it, for example by welding, in which case the hinge eye 20.2 would have to be provided on the rod coupling 9. According to a further alternative, both the rod 4 and the rod coupling 9 could be provided with joint eyes 20.2 and connected via a separate joint pin 20.1.

The refinements in the Fig. 4a), 5a) and 6a ) differ from the configurations in Fig. 4b), 5b) and 6b ) in that the hinge eye 20.2 is designed as a round hole in the version designated with a) and as an elongated hole in the version designated with b). With the slot solution According to embodiment b), the transverse movements of the rod 4 resulting from the embodiment designated with a) are compensated. For this reason, in the configuration according to embodiments b), a rod guide 4.1 can be used in which the rod 4 is only guided axially. The rod guides 4 therefore have a guide area 4.2, the width of which corresponds to the width of the rod 4. In the embodiments a), the rod guide 4 also allows a certain transverse movement of the rod 4 and therefore has a correspondingly wider rod guide.

The advantage of the embodiment designated with a) compared to the embodiment designated with b) is that it results in significantly less friction, in particular with a larger number of locks 3.

Like comparing the representations in the Figures 4, 5 and 6 This shows that the axial movements of the rod 4 are converted into a pivoting movement of the rod coupling 9 designed as a pivot lever. By pivoting the rod coupling 9, the locking element 3.1 of the lock 3 is also pivoted. The rod coupling 9 and the locking element 3.1 are rotatably connected to one another. The locking angle α _{V of} the locking element 3.1 and the pivot angle α _{S of} the rod coupling 9 are therefore the same, cf. Figure 6a ) and b). In the exemplary embodiments, the locking angle α _{V of} the locking element 3.1 and the pivot angle α _{S of} the rod coupling 9 between the open and closed positions of the locking element 3.1 are each 90 °.

The lock 3 is designed as a turn-clamp lock, which is why the locking element 3.1 also moves axially in addition to this rotational movement by the locking angle α _V for tensioning a door seal as best based on the illustrations in the Fig. 4c), 5c) and 6c ) becomes clear.

In Figure 4c ) the locking element 3.1 initially has a larger axial distance A ₁ with respect to the door frame 102. As a result of the movement of the rod 4, the rod coupling 9 and with it the locking element 3.1 are pivoted, as can be seen from the comparison with the illustrations in FIG Fig. 4 with those in Fig. 5 shows. As a result, the locking element 3.1 engages behind the door frame 102 so that the door leaf 101 can no longer be opened. Like the comparison of the representation in the 4c) and 5c ) reveals this in particular, this pivoting movement was superimposed by an axial movement of the locking element 3.1 along its locking axis V. The distance A _{2 of} the locking element 3.1 relative to the door frame 102 is therefore in the position according to FIG Figure 5c ) compared to the open position in Figure 4c ) decreased.

By moving the rod 4 further, the locking element 3.1 is pivoted further and also moved further axially. The pivoting movement and the axial movement of the locking element 3.1 are superimposed on one another, at least partially. Both movements take place simultaneously until the in Fig. 6 shown closed position is reached. In this position, the locking element 3.1 rests against the door frame 102 and tensions the door seal. The distance A ₃ is equal to zero in this position.

Details of the lock 3 are shown in the exploded view Figure 7a ) to recognize.

The lock 3 is connected at one end to the rod coupling 9 designed as a pivot lever. The rod coupling 9 is coupled with its one lever end 9.1 to a locking shaft 3.2 of the lock 3 in a rotationally fixed but axially movable manner. The locking shaft is for this purpose 3.2 guided axially movably in a locking housing 3.1. The rotary movements, which are applied to the locking shaft 3.2 via the rod coupling 9, are carried out via two guide tracks 3.4 arranged on opposite sides of the locking shaft 3.2 and a guide element 3.5 engaging in the guide track 3.4, which is designed like a bolt and arranged on the movable locking shaft 3.2 is converted into an axial movement along the locking axis V. In this way, the locking element 3.1 arranged at the other end of the locking mechanism 3 is rotated and clamped. The locking element 3.1 is firmly connected to the shaft 3.2. The connection of the locking element 3.1 to the shaft 3.2 can take place via a screw connection or a similar element, for example a square or the like. A spring 9.3 is provided between the rod coupling 9 and the axially movable locking shaft 3.2, via which the locking shaft 3.2 is axially pretensioned.

As the Figure 7b ) This illustrates, an actuator 50 could be used instead of the rod coupling 9, which would result in a twist-and-turn lock, which can be used not only on a rod lock 1, but alternatively also as a single-point lock in the manner of a cam. For use in the rod lock 1, the rod coupling 9 would have to be connected to the actuation 50 in the area of an actuating element 51 of the actuation 50, which is designed as a square in the exemplary embodiment. This would result in a two-part rod coupling 9 with the possibility of using the lock 3 as a single-point lock in the manner of a sash.

Figure 7c ) finally shows a locking element 3.1 designed as a roller tongue. The locking element 3.1 according to Figure 7c ) can alternatively to the locking element 3.1 designed as a tongue according to Figure 7a ) are arranged on the locking shaft 3.2. Using the as Rolling tongue designed locking element 3.1 can realize a larger axial clamping path, cf. also the representation in Fig. 3 .

Based on the representations in the Figures 8 to 12 details of the rod coupling 8 and two versions of the emergency release 5 will be explained below.

In the 8a) and 8b ) the area of the actuation 2 of the rod lock 1 is shown in an enlarged view. Figure 8a ) shows the rod lock 1 in the closed state, Figure 8b ) shows the open state. To remove clasp 1 from the in Figure 8a ) into the position shown in Figure 8b ) to transfer the position shown, the actuation 2 is gripped by hand and rotated by 90 °. Corresponding to the rotary movement of the actuator 2, the rod coupling 8 also begins to pivot through 90 °, whereby the locks 3 provided on the rod lock 1 are actuated in the manner described above.

Like the comparison between the 8a) and 8b ), the emergency release 5 has no function in this normal operation of the rod lock 1, but is coupled to the rod 4 of the rod lock 1 and follows the movements of the rod 4.

The emergency release 5 is designed in the manner of an unlocking slide which can be actuated in emergency situations as an alternative to the actuation 2. The emergency release 5 has a decoupling device 6 in the area of the actuation 2, via which the actuation 2 can be mechanically decoupled from the rod 4 in the area of the articulated connection with the rod 4. In addition, the emergency release 5 has an emergency actuation 7, by means of which the locks 3 of the rod lock 1 can be actuated after the actuation 2 has been decoupled. The emergency release 5 is designed as a one-hand operation, so that both the decoupling the rod 4 of the actuation 2 as well as the actuation of the locks 3 can be accomplished with just one hand. For this purpose, the emergency release 5 is to be grasped by hand and moved along the arrow P provided on the emergency release 5. The displaceable parts of the emergency release 5 are held in a signal color, for example in red, orange or a similar color, so that intuitive operation results even under poor visibility.

Fig. 9 shows one of the representation in Figure 8a ) Corresponding view of the rod lock 1 in a partially sectioned view to explain the details of the decoupling device 6 and the emergency actuation 7 of the emergency release 5.

The decoupling device 6 is provided in the area of one end of the emergency release 5. The decoupling device 6 has a movably mounted decoupling element 6.1 which is arranged in a receptacle 8.1 of the rod coupling 8. In the in Fig. 9 In the illustrated position, the bolt-like decoupling element 6.1 together with the receptacle 8.1 forms an articulated connection of the rod coupling 8 with the rod 4 in accordance with the functionality described above for the joint 20.

The receptacle 8.1 of the rod coupling 8 is provided on the end of the rod coupling 8 which is opposite the actuation axis of the actuating element 2 and is connected to it in a rotationally fixed manner. The decoupling element 6.1 is designed as a spring bolt. The decoupling element 6.1 has a bolt 6.1.1 pretensioned by a spring 6.1.2 in the direction of the decoupling position. In Fig. 9 the coupling position is shown in which the decoupling element 6.1 is secured in position via a securing element 6.2. In the coupling position, the bolt 6.1 is inserted into a correspondingly designed opening 4.3 of the rod 4, cf. also Figure 10d ). This results in an articulated connector in the Area of the rod-side end of the rod coupling 8 with the rod 4. On the opposite side, the decoupling element 6.1 is held via the securing element 6.2. The decoupling element 6.1 has at its end facing away from the rod 4 a bolt head 6.1.3 designed in the manner of a radial thickening, which dips into a securing receptacle 6.2.2 of the securing element 6.2.

The emergency actuation 7 has a driving device 7.1 in the area of the rod 4. The driver device 7.1 has an elongated hole 7.1.1 extending in the direction of the rod 4, the end regions of which form stops 7.1.2 which cooperate with a stop 7.1.3 which is arranged fixed to the rod on the rod 4. The stop 4 fixed to the rod is designed in the manner of a socket pin projecting through the elongated hole 7.1.1. In order to guide the movements of the emergency actuation 7 with respect to the rod 4, the emergency actuation 5 also has an axial guide 7.2 in which the rod 4 is received. The rod 4 can be moved back and forth within the axial guide 7.2. The axial guide 7.2 can have a C-shaped or closed receiving cut that receives the rod 4. In addition, the emergency actuation 7 has a handle 7.3, which can be gripped by a person and used to actuate the emergency release 5. In the exemplary embodiment, the driving device 7.1, the axial guide 7.2 and the handle 7.3 of the driving device 7 and also the securing element 6.2 of the decoupling device 6 are made in one piece from a plastic material.

The mode of operation of the emergency release 5 is explained below using the illustrations in Fig. 10a) to 10d ) are explained.

Figure 10a ) shows the locked position of the rod lock 1 as shown in FIG Fig. 9 . In this position, the rod 4 is kinematically coupled to the actuator 2 via the rod coupling 8. Movements the actuation 2 are as shown in the 8a) and 8b ) transferred to the rod 4 and used to actuate the locks 3. In order to actuate the emergency release 5, the handle 7.3 of the emergency actuation 7 is gripped and moved in the direction of the arrow P relative to the rod 4, as shown in FIG Figure 10b ) is shown.

Due to the movement of the emergency release 5 relative to the rod 4, the decoupling device 6 is first activated. The decoupling element 6.1 emerges from the securing receptacle 6.2.2 of the securing element 6.2 and moves due to the bias of the spring 6.1.2 in a direction transverse to the direction of movement of the rod 4. The decoupling element 6.1 does not leave the opening 4.3 of the rod 4 jerkily, but slides along a release bevel 6.2.1 until it has finally left the opening 4.3 at the end of the decoupling path E and the rod 4 is decoupled from the actuation 2, cf. also the representation in Fig. 10 c) . In this position, the articulated connection between the rod coupling 8 and the rod 4 is separated.

As shown in Figure 10b ) this can be seen further, while the driving device 7.1, guided via its axial guide 7.2, moves relative to the rod 4. The driving device 7.1 is formed according to the length of the elongated hole 7.1.1 along a freewheel path F as long as it is fixed on the rod 4 Stop 7.1.3 moves until it comes into contact with the stop 7.1.2. This position at the end of the freewheel travel F is in Figure 10c ) shown.

In the Figure 10c ) the emergency release 5 was moved so far that the rod 4 was decoupled from the actuator 2 via the decoupling device 6. In this position, the actuation 2 can be turned without this having any effect on the position of the rod. In addition, the movable stop 7.1.3 and the fixed stop 7.1.2 lie against one another, so that the entrainment device 1 now takes the rod 4 with a further movement of the emergency release 5 along the arrow P. This is in Figure 10d ) illustrated.

As shown in Figure 10d ) the emergency release 5 was moved further in the direction of the arrow. The rod 4 was taken along, which is also evident from the increased distance between the emergency release 4 and the actuation 2 compared to the illustration in FIG Figure 10c ) reveals. In this position, the rod 4 was moved to such an extent that the locks 3 were actuated and the door leaf 101 was unlocked from the door frame 102. The axial travel of the rod 4 corresponds to that in 8a) and 8b ) shown travel path.

In order to separate the unlocking and the entrainment process from one another in terms of time, the freewheeling path F is greater than the decoupling distance E. This ensures that in the first movement section of the emergency unlocking device 5, the decoupling device 6 initially reliably decouples the rod 4 from the actuation 2 takes place before the actuation of the locks 3 then takes place in a second movement section via the emergency actuation 7.

By actuating the emergency release 5, it is possible in this way to achieve reliable and easy-to-use unlocking of the door leaf 101 in emergency situations with just one hand. The emergency release 5 has a kind of double function in that it ensures, via the decoupling device 6, both a decoupling of the actuation 2 from the rod and an actuation of the locks 3 by moving the rod 4. The emergency release 5 can therefore be used independently of the number of existing locks 3 for different types of rod locks 1.

In the Figures 11 and 12 a second embodiment of an emergency release 5 is shown.

The emergency release 5 as shown in the Figures 11 and 12 In contrast to the emergency release 5 described above, it is designed as a two-hand operation. A bolt 6.1.1 pretensioned by a spring 6.1.2 serves as the decoupling device 6. However, the bolt 6.1.1 is not biased in the direction of the decoupling position via the spring 6.1.2, but in the direction of the coupling position. In order to release the coupling of the bolt 6.1.1 from the rod 4, it must be gripped via a handle 11 and pulled out of the opening 4.3 of the rod 4 against the force of the tensioning spring 6.1.2. As soon as the rod 4 has been decoupled from the actuation 2 in this way, the emergency actuation 7 can then be actuated with a second hand. In this embodiment, the emergency actuation 7 is designed as a driving device 7.1 firmly connected to the rod 4. The entrainment device 7.1 also has a handle 12 on which the operator's hand can be placed in order to move the entrainment device 7.1.

To operate the emergency release 5 according to the Figures 11 and 12 it is therefore necessary that the operator first pulls the spring bolt 6.1.1 out of the opening 4.3 of the rod 4 in order to kinematically decouple the rod 4 from the actuation 2. Holding the bolt 6.1.1 in this position, the driver device 7.1 is then gripped by its handle 12 with the second hand and the rod is moved in a next step. As a result, all of the locks 3 connected to the rod 4 are actuated. This also enables the rod locks 1 to be emergency unlocked independently of the number of locks 3 present.

An advantage of the second embodiment of the emergency release is its structurally simple and inexpensive structure, a disadvantage compared to the design according to the Figs. 8-10 is that both hands of the operator are required to unlock the door leaf 101.

In the following, details of a corner deflection 30 are based on the illustrations in FIGS Figs. 13-18 explained.

Fig. 13 shows first a rod lock 1 which is provided with two corner deflections 30. The in Fig. 13 The rod lock 1 shown corresponds to the rod locks 1 described above and can in particular also be provided with an emergency release 5 according to one of the embodiments described above.

The corner deflections 30 serve to control the movements of the embodiment according to Fig. 13 along a vertical edge of the door leaf 101 extending rod 4 to be transferred to the rods 14 arranged transversely to this. The rods 14 do not extend along a vertical edge of the door leaf 101, but rather along the horizontal upper edge and the horizontal lower edge of the door leaf 101 in order to actuate the locks 3 provided there. The locks 3 are identical in every detail to the locks 3 described above. Likewise, the coupling of the rod 4 via the rod couplings 9 to the locks 3 and the rod coupling 8 for coupling the rod 4 to the confirmation 2.

The way in which the corner drive 30 functions can best be seen on the basis of the illustrations in FIG Fig. 14 detect. The corner deflection 30 has an overall angular geometry, the two legs of the angle being angled at 90 ° to one another. Figure 14a ) shows the open position of the rod lock 1. In this, the locking elements 3.1 of the locks 3 are in their open position. To lock the door leaf 101 to the door frame 102 of the door 100, the rod 4 is actuated 2 is actuated and moves in the representation in Figure 14a ) downward. This movement is transmitted to the locks 3 via the rod couplings 9. The corner deflection 30 is provided so that the movement of the rod 4 can also be transmitted to the rod 14 and from this via the rod coupling 9 provided there to the lock 3. The end of the rod 4 is connected to a mounting element 40 of the corner drive 30. The rod 14 is also connected at one end to a mounting element 40 of the corner drive 30. The two assembly elements 40 are arranged on a flexible deflection element 31 which is arranged within a guide 35 of the corner deflection 30.

Like the comparison of the representation in the Fig. 14a) and 14 b) shows, the movement of the rod 4 is also transmitted to the rod 14 via the corner deflection 30 and deflected at right angles until, as shown in FIG Figure 14c ) the locks 3 are locked. In a corresponding manner, the locks 3 can also be released again by moving the rod 4 in the other direction. The movement of the rod 4 required for this can be generated via the actuation 2 or, in emergencies, also via the emergency release 5.

De Figures 15 to 17 show the structure of the corner drive 30. The corner drive 30 is composed of two housing halves 33, 34. Fig. 15 shows a perspective view of the lower housing half 34 with the deflecting element 31 received in it such that it can slide in two directions. The deflecting element 31 can be a flexible element that transmits both tensile and compressive forces. In the exemplary embodiment, the deflecting element is a flexible sheet metal strip made of spring steel. The deflecting element 31 is guided within a rail-like guide 35 of the housing 32. The deflecting element 31 has mounting elements 40 at its ends. The two mounting elements 40 at the ends of the deflecting element 31 are of identical design. The mounting elements 40 each have a mounting bracket 43 designed in the manner of a flat plate and a guide area 44 extending transversely with respect to the mounting bracket 43. The guide area 44, like the deflection element 31, is guided in the guide 35 of the housing 32. As shown in Fig. 17 can be seen, the guide 35 has for this purpose a guide area 35.1 in which the guide area 44 of the mounting element 40 is guided. The guide area 35 also has a guide area 35.2 in which the deflecting element 31 is guided. The guide area 35.2 extends continuously over the entire length of the corner deflection 30. The guide area 35.1 is interrupted in the area of the corner of the angular corner deflection 32.

The assembly elements 40 are provided with several assembly points 41, 42 in the area of the assembly bracket 43. The mounting points 41, 42 can be used optionally, depending on the way in which the rod 4, 14 to be attached to them moves.

In the embodiment according to Fig. 13 For example, the rod 4 is moved essentially in the longitudinal direction of the rod, with it also executing certain transverse movements due to the rod coupling formed as a parallelogram rod 10. In order to enable these transverse movements, one of the mounting points 42 is designed as an elongated hole. Therefore, translational movements of the rod 4 are permitted within the assembly point 42, which is designed as an elongated hole. In contrast to the rod 4, a certain pivoting movement takes place in the rod 14 during the actuation of the rod lock 1. For this reason, the rod 14 is fastened in a mounting point 41, which is designed as a hinge eye and allows rotational movements of the rod 14.

The mounting point 42 is characterized in that a translational degree of freedom of the rod 4 attached to it is maintained. The assembly point 41 is distinguished by the fact that a rotational degree of freedom of the rod 14 connected to it is maintained.

In the exemplary embodiment, two mounting points 41 designed in the manner of an articulated eye and one assembly point 42 designed in the manner of an elongated hole are provided. So there are two similar mounting points 41 and a different mounting point 42 are provided. The different mounting point 42 is located between the mounting points 41 of the same type. The arrangement is selected symmetrically in such a way that, regardless of the orientation of the corner drive 30, one of the mounting points 41 and the mounting point 42 can always be occupied. The corner deflection 30 can therefore in a rod lock 1 as shown in FIG Fig. 13 can be used both as upper corner drive 30 and as lower corner drive 30.

For the symmetrical introduction of forces into the corner deflection 30, the mounting bracket 43 is arranged asymmetrically with respect to the guide region 44 of the mounting element 40. While the guide area 44 is arranged symmetrically to the parting plane T of the two housing halves 33, 34 of the housing 32, the mounting bracket 43 has a certain offset with respect to the parting plane T of the housing 32. The offset of the mounting bracket 43 with respect to the parting plane T corresponds to half the thickness of the rods 4, 14. In this way, the center plane of the rods 4, 14 is in alignment with the parting plane T of the housing 42. This results in a favorable introduction of force .

The assembly of the corner deflections 30 on the door leaf 101 of the door 100 is explained below with reference to the illustration in FIG Fig. 18 explained.

The housing 32 of the corner drive 30 has a multiplicity of fastening bores 45 via which the corner drive 30 can be fastened to the inside of the door leaf 101. For this purpose, welding studs 46 are first attached to the inside of the door leaf 101 in a suitable position. After the welding studs 46 have been welded to the inside of the door leaf, the angular corner deflection 30 with its fastening bores 45 can be aligned with respect to the welding stud 46 and pushed onto it. Since the welding studs 46 have a radial widening at their door-side end, the fastening bores 45 have an opening that accommodates the radial widening in the assembled state. Undesired stresses on the door leaf 101, which could lead to the position of the welding studs 46 being recognizable from the outside of the door, are thereby avoided.

After the corner drive 30 has been placed and secured by means of appropriate securing elements, the rods 4, 14 can be connected to the corresponding mounting points 41, 42.

The corner deflection 30 can be used flexibly with different types of rod locks 1 by providing mounting points 41 which allow rotational movements of the rod 14 and also mounting points 42 which allow translational and, if necessary, rotational movements of the rod 4. The differently designed mounting points 41, 42 can be used optionally. This results in a highly flexible assembly option for connecting the different rods 4, 14 with one and the same corner deflection 30.

The rod locks 1 described above are characterized by a particularly advantageous configuration of the locks 3 as twist-and-turn locks, by means of which a door seal can be tensioned at several points, and their structurally simple and reliable coupling with the rod 4 via rod couplings 9 designed as a pivot lever. Further advantages of the rod locks 1 result from the emergency unlocking 5, which is easy to operate even in the case of many locks 3. In addition, the corner deflection 30 that can be used in the rod locks 1 allows a flexible connection of different rods 4, 14.
