Description

The invention relates to a rod lock for locking a door leaf to a door frame with at least one lock and an actuator for actuating the lock, which are coupled to one another via at least one rod, as well as an emergency release for unlocking the door leaf in emergency situations. Another object of the invention is a door with a door leaf that can be moved back and forth between an open position and a closed position, a door frame and a rod lock for locking the door leaf to the door frame in the closed position.

Bar latches are used in many areas of technology to lock doors in their closed position, i.e. to lock doors. H. to lock the movable door leaf on the fixedly arranged 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 positively lock the movable door leaf in the closed position of the door on the door frame surrounding the door opening, which can be formed by the edge of the opening or a separate part, rod locks have at least one, but usually several locks.

To actuate the locks, a manually actuatable actuation is usually provided which, in a simple embodiment, can be a square, a handle or a similar element. Since the actuation and the locks are usually at a certain distance from one another, they are kinematically coupled to one another in the case of rod locks via at least one rod, rod locks with two rods also being widespread. The rods are coupled to the actuation at one end, so that the movements of the actuation, which are usually rotary movements, are converted into an axial movement of the rod. The other end of the rod is coupled to the lock, so that the axial movements of the rod are converted into a movement of a locking element provided on the lock, such as a locking tongue. Especially with larger doors, rod locks are often found in which a rod is coupled not only to one lock, but to several locks, which results in several locking points and thus a reliable locking, which is for example in the area of climatic chambers, industrial systems, control cabinets etc. can be beneficial. The locks can be distributed over the length of the rod and in particular be arranged at the two ends of the rod, but also in intermediate areas.

As a rule, the rod locks are arranged on the door leaf in such a way that the actuation can be actuated from the outside of the door, which is why it is not possible to actuate the actuation from the inside of the door.

In certain applications, this can lead to dangerous situations, which is clear from the example of walk-in climatic chambers. Such climatic chambers are distinguished by climatic conditions that can be set within a wide range inside the climatic chamber. In order to be able to enter the climatic chamber, a door which is designed to be climatically impervious to the outside is usually provided, which usually has a rod lock equipped with several locks. If a person now enters the climatic chamber, in unfavorable cases it can happen that another person closes the door while the person is still inside the climatic chamber. Since the actuation of the rod lock is on the outside of the door, the person locked in the climatic chamber is not easily able to unlock the door leaf from the door frame and in this way leave the climatic chamber, which under very unfavorable circumstances even involves a certain risk may be linked to the life and limb of the imprisoned person.

Because of this, some of the DE 10 2017 119 835 A1 Such closures are known from the field of sliding doors in which an emergency release is provided for unlocking the sliding door in emergency situations. Using the emergency release, the sliding door can also be unlocked from the side opposite the actuation, without the actual actuation of the lock having to be actuated for this purpose.

A rod lock with an unlocking option, also suitable as an emergency unlocking, from the side opposite the actuation is for example from the DD 223 490 A1 known for use in a garage door. In this rod lock, an actuation designed as a rotary handle is coupled via a rod to a lock designed as a locking slide. The locking slide is designed to be decoupled from the rod of the rod lock against the force of a spring, whereby an emergency unlocking of the garage door can also be achieved from the inside of the garage door without the actual actuation of the rod lock having to be actuated. In dangerous situations, for example in the event of a fire therefore the garage door can be opened from the inside, even if the garage door is locked from the outside.

This type of emergency release with a lock that can be decoupled from the rod and can be operated manually has proven to be advantageous for rod locks with only one lock, but is not suitable for rod locks with more than two locks. Because for emergency unlocking it is necessary with this type of rod lock that the respective lock is moved by hand against the force of a spring, which naturally causes problems from a number of three locks, especially if they are a greater distance from one another.

The object of the present invention is to provide a rod lock which is characterized by an emergency release that is easy to use regardless of the number of locks present.

In the case of a rod lock of the type mentioned at the outset, this object is achieved in that the emergency release is designed such that the rod can be decoupled from the actuation and the lock can be actuated to unlock the door leaf via the emergency release.

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.

Further details and advantages of the invention are given in particular in the dependent subclaims.

An advantageous embodiment initially 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 for the decoupling element to be biased in the other direction, that is to say in the direction of its coupling position. 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 further 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 poor visibility, since the operator recognizes the handle, which is designed in a signal color, as such even over long distances and receives information about the manner 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, the twist-clamp locks can be used not only to achieve a positive locking, but also to compress a door seal provided between the door leaf and the door frame by moving the locking element axially. This enables the door to be closed in a pressure-tight manner in the case of ventilation systems, climatic chambers or similar applications.

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 Transfer rod coupling to the lock and operate it.

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. 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.

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 to a certain extent in the area of the assembly point so as to be movable in a translatory manner. 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.

Another embodiment provides that the mounting tabs are at least partially outside of the housing and the guide region are arranged within the housing.

In addition, in the case of a door of the type mentioned at the outset, it is proposed to solve the above-mentioned object that it has a rod lock with one or more of the above-mentioned features. The advantages explained in connection with the rod lock result.

An advantageous embodiment of the door provides that the actuation is arranged on one side of the door leaf and the emergency release is arranged on the opposite side of the door leaf. In this way, the emergency release can be activated from the inside when the door is closed.

The 1a) to 1e) show some doors 100 with a pivotable opposite a fixed door frame 102 arranged door leaf 101 . By the door 100 it can be a conventional door, for example in the form of a door accessible by a person, 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 1a) to 1e) is the closed position of the door 100 shown in which the door leaf 101 on the door frame 102 is locked.

For locking the door leaf 101 on the door frame 102 is a rod lock 1 provided, which will be discussed in detail below. From the rod lock 1 is in the 1a) to 1e) only the actuation accessible from the outside of the door 2 to recognize which is the locking mechanism between the door leaf 101 and the door frame 102 can be produced or solved.

According to the configuration in 1a) it may be during actuation 2 an actuation that interacts with a tool 2 act, for example a square, a triangle or a similar element. As shown in 1b) it may be during actuation 2 also act as a handle, which has the advantage of being able to operate the actuation 2 no additional tool is required. The handle can be over a lock cylinder be designed lockable. In addition to this simple design of a handle, for example, according to the illustrations in 1c ) and 1d) also the use of swivel handles as actuation 2 conceivable which initially opposite the plane of the door leaf 101 pivoted and then rotated in a next step. Again, according to 1 c) Lock cylinders or other access control systems, such as an in 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 1e) as an actuation 2 conceivable which gripped and to actuate the actuation 2 can be rotated. The present rod lock 1 however, the actuation is independent of the configuration 2 for all types of operations 2 usable, which is why the use of anything other than that in 1a) to 1e) actuations shown is possible.

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

The rod lock 1 is on the inside of the door leaf 101 the door 100 arranged and extends parallel to an edge of the door leaf 101 . The operation 2 is on the opposite outside of the door leaf 101 arranged and in the embodiment according to 2a) to 2c ) as a handle and in the design in the 3a) to 3c ) designed as a lever handle. The operation 2 of the rod lock 1 is over a pole 4th with two locks 3 kinematically coupled. A rotary movement of the actuator 2 becomes in one movement of the rod 4th convicted. The movement of the bar 4th is used to operate the locks 3 and thus in a movement of the locking elements 3.1 the lock 3 convicted. In the design according to 2a) to 2c ) are the locking elements 3.1 as locking tongues and in the design in the 3a) to 3c ) designed as roller tongues.

The 2 and 3 each show rod locks 1 with two locks 3 , being a latch 3 above the actuation 2 and a latch 3 below the actuation 2 is arranged. However, there are also bar locks 1 with more than two locks 3 possible, for example, a three-point, a four-point, a five-point or even more locking points having locking of the door leaf 101 on the door frame 102 to provide. According to the representations in the 13ff . a locking point on the top and / or bottom of the door leaf 101 be arranged, which has a corner drive 30th also about the actuation 2 is actuated.

The following first describes in detail the coupling of the rod 4th with the latches 3 as well as the operation 2 are discussed before then on other essential aspects of the rod lock 1 and in particular details of the interlocks 3 , the emergency release 5 as well as the corner drive 30th will be received.

In the area of operation 2 is the pole 4th via a rod coupling 8th with the actuation 2 of the rod lock 1 coupled. The rod coupling 8th is in the manner of a self between the operation 2 and the rod 4th extending pivot lever formed, see. also 8th . Via the rod coupling 8th becomes a rotary movement of the actuator 2 around their actuation axis B. in an axial movement of the rod 4th transferred, taking the rod 4th in the embodiment according to 2 and 3 also moved a little to the side. One end of the coupling element 8th is with the side next to the pole 4th arranged actuation 2 non-rotatably connected. The coupling element 8th follows the rotary movements of the actuation 2 . When turning the actuator 2 the coupling element begins 8th to pivot in the manner of a pivot lever. The other end of the coupling element 8th is on the line 4th articulated so that the pivoting movements of the coupling element 8th in an axial movement of the rod 4th are transferred in the longitudinal direction and a transverse movement. The transverse movement of the rod 4th is smaller in magnitude than the axial movement.

The latches too 3 are via a rod coupling 9 with the rod 4th coupled. The rod coupling 9 is kind of one himself between the pole 4th and a lock 3 extending pivot lever formed, the pivoting movements for actuating the lock 3 serve.

For details of the rod coupling 9 will be discussed in more detail below.

Those in the area of actuation 2 provided rod coupling 8th forms together with those in the area of interlocking 3 provided rod couplings 9 and the rod 4th a parallelogram linkage 10 . The operation 2 is in a structurally simple and reliable way via the parallelogram linkage 10 with the two locks 3 coupled. On the parallelogram linkage 10 can in addition to those in the 2 and 3 shown a total of two locks 3 more locks 3 be tied to a rod lock 1 with more than two locking points, especially in the case of large door leaves 101 and high demands on the compression between the door leaf 101 and the door frame 102 arranged seal may be advantageous.

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

The movements of the rod designed as a flat rod 4th are about rod guides 4.1 guided. The rod guides 4.1 are on the inside of the door leaf 101 arranged and designed in such a way that these are also due to the parallelogram linkage 10 resulting transverse movements of the rod 4th allow, cf. 2 and 3 . The rod guides 4.1 therefore show you the bar 4th receiving leadership area 4.2 that is wider than the bar by the amount of transverse movement 4th is, cf. 2c ). This way the movements of the rod 4th both in the axial and in the transverse direction in the guides 4.1 guided.

Like the illustrations of the rod lock 1 in the 2 and 3 The rod lock shows this further 1 an emergency release 5 on which the door leaf is 101 in emergency situations, for example by a locked person, regardless of the number of locks in place 3 in a simple manner from the door frame 102 can be unlocked. This is also discussed below, in particular with reference to the representations in FIGS 8th to 12th will be discussed in more detail.

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

As shown in the 4a) and 4b) let this first be seen, show the rod locks 1 a rod designed as a flat rod 4th on. To transmit the movement of the rods 4th on the latches 3 is a rod coupling 9 intended. The rod coupling 9 is designed as a pivot lever and each has a lock 3 assigned.

The rod coupling 9 is in the area of one end of the lever 9.1 over a joint 20th articulated with the rod 4th connected, cf. especially 5a) and 5b) . The joint 20th consists of a hinge pin 20.1 that is within an articulated eye 20.2 is articulated. The other end of the lever 9.2 the rod coupling 9 is with the lock 3 coupled in such a way that the pivoting movements of the rod coupling 9 in a corresponding rotary movement of the locking element 3.1 around its locking axis V be convicted.

The joint eye 20.2 gets stuck by one 4th arranged through hole formed, whereby the rod 4th has a simple structure. Alternatively, the hinge pin could also be used 20.1 At the rod 4th be arranged and connected to this for example by welding, in this case the hinge eye 20.2 at the rod coupling 9 should be provided. According to a further alternative, both the rod 4th as well as the rod coupling 9 with joint eyes 20.2 provided and a separate hinge pin 20.1 be connected.

The refinements in the 4a) , 5a) and 6a) differ from the configurations in 4b) , 5b) and 6b) in that the joint 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). In the elongated hole solution according to version b), the transverse movements of the rod resulting from the version designated with a) are 4th balanced. For this reason, a rod guide can be used in the configuration according to embodiments b) 4.1 be used in which the rod 4th is only guided axially. The rod guides 4th therefore have a leadership area 4.2 on whose width is the width of the rod 4th corresponds. In the configurations a) the rod guide allows 4th also some transverse movement of the rod 4th 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 4th , 5 and 6th this shows the axial movements of the rod 4th into a pivoting movement of the rod coupling designed as a pivot lever 9 convicted. By pivoting the rod coupling 9 also becomes the locking element 3.1 the lock 3 pivoted. The rod coupling 9 and the locking element 3.1 are rotatably connected to each other. The locking angle α _v of the locking element 3.1 and the swivel angle α _s the rod coupling 9 are therefore the same, cf. 6a) and b). In the exemplary embodiments, the locking angle is α _v of the locking element 3.1 and the swivel angle α _s the rod coupling 9 between the open and closed positions of the locking element 3.1 90 ° each.

The lock 3 is designed as a turn-clamp lock, which is why the locking element 3.1 in addition to this rotary movement by the locking angle α _v is also moved axially to tension a door seal, as best shown in the illustrations 4c ), 5c) and 6c) becomes clear.

In 4c ) has the locking element 3.1 initially a larger axial distance A ₁ opposite the door frame 102 on. By moving the bar 4th becomes the rod coupling 9 and with this the locking element 3.1 pivoted, as the comparison with the representations in 4th with those in 5 shows. This engages behind the locking element 3.1 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) shows this in particular, this pivoting movement was caused by an axial movement of the locking element 3.1 along its locking axis V superimposed. The distance A ₂ of the locking element 3.1 opposite the door frame 102 is therefore in the position according to 5c ) compared to the open position in 4c ) decreased.

By moving the bar further 4th becomes the locking element 3.1 pivoted further and also moved further axially. The pivoting movement and the axial movement of the locking element 3.1 are superimposed, at least partially. Both movements take place simultaneously until the in 6th shown closed position is reached. The locking element is in this position 3.1 on the door frame 102 and tightens the door seal. The distance A ₃ is zero in this position.

Lock details 3 are in the exploded view according to 7a) to recognize.

The lock 3 is at one end with the rod coupling designed as a pivot lever 9 connected. The rod coupling 9 is with one end of the lever 9.1 with a locking shaft 3.2 the lock 3 rotatably, but axially movably coupled. The locking shaft is used for this 3.2 in a lock housing 3.1 axially movably guided. The rotary movements that occur via the rod coupling 9 onto the locking shaft 3.2 are applied over two on opposite sides of the locking shaft 3.2 arranged guideways 3.4 and one in the guideway 3.4 engaging guide element 3.5 , which is designed in the manner of a bolt and attached to the movable locking shaft 3.2 is arranged in an axial movement along the locking axis V convicted. In this way there is a turning-clamping movement of the at the other end of the lock 3 arranged locking element 3.1 . The locking element 3.1 is with the wave 3.2 firmly connected. The connection of the locking element 3.1 with the wave 3.2 can be done via a screw connection or a similar element, for example a square or the like. Between the rod coupling 9 and the axially movable locking shaft 3.2 is a feather 9.3 provided over which the locking shaft 3.2 is axially preloaded.

As the 7b) this illustrated could be used in place of the rod coupling 9 also an activity 50 can be used, which would create a twist-and-turn fastener that is not only attached to a rod fastener 1 , but alternatively can also be used as a single-point locking system in the manner of a fastener. For use with the rod lock 1 would need the rod coupling 9 in the area of an actuating element 51 of actuation 50 , which is designed as a square in the embodiment, with the actuation 50 get connected. This would result in a two-part rod coupling 9 with the possibility of locking 3 Can also be used as a single-point locking system like a fastener.

7c ) finally shows a locking element designed as a roller tongue 3.1 . The locking element 3.1 according to 7c ) can be used as an alternative to the locking element designed as a tongue 3.1 according to 7a) on the locking shaft 3.2 to be ordered. By using the locking element designed as a roller tongue 3.1 a larger axial clamping path can be achieved, cf. also the representation in 3 .

Based on the representations in the 8th to 12th details of the rod coupling are given below 8th as well as two versions of the emergency release 5 explained.

In the 8a) and 8b) is the area of operation 2 of the rod lock 1 shown in an enlarged view. 8a) shows the rod lock 1 when closed, 8b) shows the open state. Around the clasp 1 from the in 8a) position shown in 8b) To transfer the position shown, the actuation 2 gripped by hand and rotated 90 °. According to the rotary movement of the actuation 2 the rod coupling begins 8th also to pivot by 90 °, whereby the on the rod lock 1 provided locks 3 be operated in the manner previously described.

Like the comparison between the 8a) and 8b) can be seen has the emergency release 5 in this normal operation of the rod lock 1 not a function, but is with the rod 4th of Rod lock 1 coupled and follows the movements of the bar 4th .

The emergency release 5 is an alternative to the actuation in emergency situations 2 actuatable unlocking slide formed. The emergency release 5 points in the area of operation 2 a decoupling device 6th on which the actuation 2 in the area of the articulated connection with the rod 4th off the shelf 4th can be mechanically decoupled. In addition, the emergency release 5 an emergency actuation 7th on which the latches are 3 of the rod lock 1 after the actuation has been decoupled 2 let actuate. The emergency release 5 is designed as a one-hand operation, so that both the decoupling of the rod 4th of the operation 2 as well as the actuation of the locks 3 can be done with just one hand. The emergency release is used for this 5 by hand and along the to the emergency release 5 provided arrow P to move. The sliding parts of the emergency release 5 are kept in a signal color, for example in red, orange or a similar color, so that intuitive operation results even under poor visibility.

9 shows one of the representation in 8a) corresponding view of the rod lock 1 in a partially sectioned view to explain the details of the decoupling device 6th as well as the emergency actuation 7th the emergency release 5 .

In the area of one end of the emergency release 5 is the decoupling device 6th intended. The decoupling device 6th has a movably mounted decoupling element 6.1 on which one in a recording 8.1 the rod coupling 8th is arranged. In the in 9 The position shown forms the bolt-like decoupling element 6.1 together with the recording 8.1 an articulated connection of the rod coupling 8th with the rod 4th corresponding to that previously for the joint 20th described functionality.

The recording 8.1 the rod coupling 8th is on that of the actuation axis of the actuation element 2 opposite end of the rod coupling connected to it in a rotationally fixed manner 8th intended. The decoupling element 6.1 is designed as a spring bolt. The decoupling element 6.1 has a feather 6.1.2 bolts prestressed in the direction of the uncoupling position 6.1.1 on. In 9 the coupling position is shown in which the decoupling element 6.1 via a fuse element 6.2 is secured in position. The bolt is in the coupling position 6.1 into a correspondingly designed opening 4.3 the pole 4th inserted, cf. also 10d ). This results in an articulated plug connection in the area of the rod-side end of the rod coupling 8th with the rod 4th . On the opposite side is the decoupling element 6.1 via the fuse element 6.2 held. The decoupling element 6.1 points to his the pole 4th remote end a bolt head designed in the manner of a radial thickening 6.1.3 on which in a backup recording 6.2.2 of the fuse element 6.2 immersed.

The emergency actuation 7th points in the area of the pole 4th a driving device 7.1 on. The take-away device 7.1 points one in the direction of the pole 4th extending elongated hole 7.1.1 on whose end stops 7.1.2 form which with a pole fixed to the pole 4th arranged stop 7.1.3 work together. The rod-mounted stop 4th is like a slot 7.1.1 protruding socket pin formed. To the movements of the emergency override 7th opposite the pole 4th to guide, the emergency actuation 5 also an axial guide 7.2 on in which the pole 4th is recorded. Inside the axial guide 7.2 can the pole 4th be moved back and forth. The axial guide 7.2 can one the pole 4th have receiving C-shaped or closed receiving cut. In addition, the emergency actuation 7th a handle 7.3 which is grasped by a person and to actuate the emergency release 5 can be used. In the exemplary embodiment, the driving device 7.1 , the axial guide 7.2 as well as the handle 7.3 the driving device 7th and also the fuse element 6.2 the decoupling device 6th made in one piece from a plastic material.

How the emergency release works 5 is explained below using the illustrations in 10a) to 10d ) are explained.

10a) shows the locked position of the rod lock 1 as shown in 9 . The bar is in this position 4th via the rod coupling 8th with the actuation 2 kinematically coupled. Movements of actuation 2 are as shown in the 8a) and 8b) on the pole 4th transmitted and to operate the locks 3 utilized. To the emergency release 5 to operate becomes the handle 7.3 emergency actuation 7th grabbed and in the direction of the arrow P opposite the pole 4th moves like this in 10b) is shown.

Due to the movement of the emergency release 5 opposite the pole 4th first becomes the decoupling device 6th activated. The decoupling element 6.1 exits the backup recording 6.2.2 of the fuse element 6.2 and moves due to the preload of the spring 6.1.2 in a direction transverse to the direction of movement of the rod 4th . The decoupling element 6.1 leaves the opening 4.3 the pole 4th not jerkily, but glides along an unlocking slope 6.2.1 until it finally comes to the end of the decoupling path E. the opening 4.3 has left and the pole 4th of the operation 2 is decoupled, cf. also the representation in 10 c) . The articulated connection between the rod coupling is in this position 8th and the rod 4th Cut.

As shown in 10b) This can be seen further, the entrainment device moves 7.1 , guided via their axial guide 7.2 , opposite the pole 4th . The driving device 7.1 according to the length of the elongated hole 7.1.1 along a freewheeling path F. as long as it is fixed on the rod 4th trained stop 7.1.3 moves until it hits the stop 7.1.2 got into plant. This position at the end of the freewheeling path F. is in 10c ) shown.

In the 10c ) became the emergency release 5 moved so far that over the decoupling device 6th the pole 4th of the operation 2 has been decoupled. In this position, the actuation 2 rotate without this having any effect on the position of the rod. The movable stop is also located 7.1.3 and the fixed stop 7.1.2 together so that the driving device 1 if the emergency release is moved again 5 along the arrow P now the pole 4th takes away. This is in 10d ) illustrated.

As shown in 10d ) became the emergency release 5 moved further in the direction of the arrow. In doing so, the pole 4th taken away, which can also be seen from the increased distance between the emergency release 4th compared to the operation 2 compared to the representation in 10c ) reveals. In this position the bar was 4th moved so far that the latches 3 operated and the door leaf 101 from the door frame 102 has been unlocked. The axial travel of the rod 4th corresponds to that in the 8a) and 8b) travel path shown.

The freewheeling path is used to separate the unlocking and driving processes from one another in time F. greater than the decoupling distance E. . In this way it is ensured that in the first movement section the emergency release 5 via the decoupling device 6th first of all, reliably decoupling the rod 4th of the operation 2 takes place before then in a second movement section via the emergency actuation 7th the actuation of the locks 3 he follows.

By pressing the emergency release 5 In this way, the door leaf can be unlocked reliably and easily with just one hand 101 reach in emergency situations. The emergency release 5 has a kind of double function in that it is connected to the decoupling device 6th both for a decoupling of the actuation 2 off the bar as well as for actuating the locks 3 by moving the rod 4th cares. The emergency release 5 is therefore independent of the number of existing locks 3 for different types of rod locks 1 equally applicable.

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

The emergency release 5 according to the representations in 11 and 12th is in contrast to the emergency release described above 5 designed as two-hand control. As a decoupling device 6th in turn serves a via a spring 6.1.2 preloaded bolt 6.1.1 . The bolt 6.1.1 is about the pen 6.1.2 however, not biased in the direction of the decoupling position, but in the direction of the coupling position. To the coupling of the bolt 6.1.1 off the shelf 4th to solve it, it must have a handle 11 gripped and against the force of the tensioning spring 6.1.2 from the opening 4.3 the pole 4th be pulled out. Once in this way the rod 4th of the operation 2 has been decoupled, the emergency operation can then be performed with a second hand 7th be made. The emergency actuation 7th is in this configuration as one with the rod 4th firmly connected driving device 7.1 educated. The take-away device 7.1 also has a handle 12th on which the operator's hand to move the driving device 7.1 can be created.

For operating the emergency release 5 according to the 11 and 12th it is therefore necessary that the operator first pulls the spring bolt 6.1.1 from the opening 4.3 the pole 4th pulls out to the pole 4th of the operation 2 kinematically decoupled. The bolt 6.1.1 Holding in this position is the next step with the second hand, the driving device 7.1 on their handle 12th grabbed and moved the rod. This actuates all of the rods 4th connected locks 3 . This also allows rod locks 1 with independent of the number of existing locks 3 emergency release.

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

The following are details of a corner drive 30th based on the representations in the 13 to 18th explained.

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

The corner drives 30th serve to control the movements of the embodiment according to 13 along a vertical edge of the door leaf 101 extending rod 4th on the bars arranged transversely to this 14th transferred to. The poles 14th do not extend along a vertical edge of the door panel 101 , but along the horizontal upper edge and the horizontal lower edge of the door leaf 101 to the locks provided there 3 to operate. The latches 3 agree in every detail with the locks described above 3 match. Likewise the coupling of the rod 4th via the rod couplings 9 with the latches 3 as well as the rod coupling 8th for coupling the rod 4th with the confirmation 2 .

How the corner drive works 30th can best be seen from the representations in 14th detect. The corner drive 30th is of an overall angular geometry, the two legs of the angle being angled by 90 ° to each other. 14a) shows the open position of the rod lock 1 . The locking elements are located in this 3.1 the locks 3 in their open position. For locking the door leaf 101 on the door frame 102 the door 100 becomes the pole 4th about the operation 2 is pressed and moves in the representation in 14a) downward. This movement is via the rod couplings 9 on the latches 3 transfer. So that the movement of the rod 4th also on the pole 14th and from this via the rod coupling provided there 9 on the latch 3 can be transferred is the corner drive 30th intended. The end of the pole 4th is with a mounting element 40 the corner drive 30th connected. Also the pole 14th is at one end with a mounting element 40 the corner drive 30th connected. The two mounting elements 40 are on a flexible deflection element 31 arranged, which within a guide 35 the corner drive 30th is arranged.

Like the comparison of the representation in the 14a) and 14 b) shows is via the corner drive 30th the movement of the bar 4th also on the pole 14th transferred and deflected at right angles until as shown in 14c ) the latches 3 are locked. The locks can be adjusted in a corresponding manner 3 by moving the rod 4th loosen again in the other direction. The movement of the rod required for this 4th can about the actuation 2 or in emergencies also via the emergency release 5 be generated.

De 15th to 17th show the structure of the corner drive 30th . The corner drive 30th consists of two halves of the housing 33 , 34 composed. 15th shows the lower housing half in a perspective view 34 with the deflecting element received in this slidable in two directions 31 . With the deflection element 31 it 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 deflection element 31 is within a rail-like guide 35 of the housing 32 guided. The deflecting element has at its ends 31 Assembly elements 40 on. The two mounting elements 40 at the ends of the deflection element 31 are designed identically. The assembly elements 40 each have a mounting bracket designed in the manner of a flat plate 43 and one across opposite the mounting bracket 43 extensive guide area 44 on. The leadership area 44 is just like the deflection element 31 in leadership 35 of the housing 32 guided. As shown in 17th shows the leadership 35 a management area for this purpose 35.1 in which the leadership area 44 of the mounting element 40 to be led. The leadership area 35 also has a guide area 35.2 on in which the deflecting element 31 is led. The leadership area 35.2 extends continuously over the entire length of the corner drive 30th . The leadership area 35.1 is in the area of the corner of the angular corner drive 32 interrupted.

The assembly elements 40 are in the area of the mounting bracket 43 with several mounting points 41 , 42 Mistake. The assembly points 41 , 42 can optionally be used, depending on how the rod to be attached to them is located 4th , 14th emotional.

In the embodiment according to 13 about becomes the pole 4th moved essentially in the longitudinal direction of the rod, this being due to the parallelogram linkage 10 trained linkage coupling also performs certain transverse movements. To enable these transverse movements is one of the assembly points 42 designed as an elongated hole. Within the assembly point designed as an elongated hole 42 therefore translational movements of the rod 4th authorized. In contrast to the pole 4th takes place at the bar 14th during the actuation of the rod lock 1 a certain pivoting movement. Because of this, the pole becomes 14th in a assemblage point 41 attached, which is designed as a hinge eye and rotatory movements of the rod 14th allows.

The assembly point 42 is characterized by the fact that the rod attached to it has a translational degree of freedom 4th preserved. The assembly point 41 is characterized by the fact that the rod connected to it has a rotational degree of freedom 14th preserved.

In the exemplary embodiment, there are two mounting points designed in the manner of an articulated eye 41 and a mounting point designed in the manner of an elongated hole 42 intended. So there are two similar assembly points 41 and a different assembly point 42 intended. The different assembly point 42 is located between the similar assembly points 41 . The arrangement is selected to be symmetrical in such a way that it is independent of the orientation of the corner deflection 30th optionally always one of the mounting points 41 as well as the assembly point 42 can be occupied. The corner drive 30th can therefore with a rod lock 1 as shown in 13 both as an upper corner drive 30th as well as a lower corner drive 30th be used.

For the symmetrical introduction of forces into the corner drive 30th is the mounting bracket 43 asymmetrical in relation to the management area 44 of the mounting element 40 arranged. During the leadership area 44 symmetrical to the parting plane T of the two housing halves 33 , 34 of the housing 32 is arranged, has the mounting bracket 43 a certain offset from the parting plane T of the housing 32 on. The offset of the mounting bracket43 in relation to the parting line T corresponds to half the thickness of the rods designed as flat rods 4th , 14th . This is how the center plane of the bars is located 4th , 14th in alignment with the parting plane T of the housing 42 . This results in a favorable introduction of force.

The assembly of the corner drives 30th on the door leaf 101 the door 100 should be based on the representation in the 18th explained.

The case 32 the corner drive 30th has a large number of mounting holes 45 on which the corner drive 30th on the inside of the door leaf 101 can be attached. This is done on the inside of the door leaf 101 first weld studs in a suitable position 46 appropriate. After the welding studs 46 were welded on the inside of the door leaf, the angled corner drive 30th with their mounting holes 45 compared to the welding stud 46 be aligned and attached to this. As the welding stud 46 have a radial widening at the door-side end, the fastening bores 45 a franking that accommodates the radial expansion in the assembled state. Unwanted tension on the door leaf 101 that could cause the position of the welding studs 46 can be seen from the outside of the door.

After the corner drive 30th have been put on and secured with appropriate securing elements, the rods 4th , 14th with the corresponding mounting points 41 , 42 get connected.

The corner drive 30th can be flexible with different types of rod locks 1 used by mounting points 41 are provided which rotational movements of the rod 14th allow and also assembly points 42 are provided which translatory and, if necessary, rotational movements of the rod 4th allow. The differently designed assembly points 41 , 42 can be used optionally. The result is a highly flexible assembly option for connecting the different rods 4th , 14th with one and the same corner drive 30th .

The rod locks described above 1 are characterized by a particularly advantageous emergency release 5 out. Further advantages of the rod locks 1 result from the design of the locks 3 as turn-clamp locks, through which a door seal can be clamped at several points, as well as their structurally simple and reliable coupling with the rod 4th via rod couplings designed as swivel levers 9 . In addition, this allows the rod locks 1 usable corner drive 30th a flexible connection of different poles 4th , 14th .
