Description

The invention relates to a bar lock for locking a door leaf on 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 bar, and an emergency release for unlocking the door leaf in emergency situations. A further subject matter of the invention is a door with a door panel 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 panel on the door frame in the closed position.

Bar locks are used in many areas of technology to lock doors in their closed position, i. H. to lock the movable door leaf to the fixedly arranged door frame. In this context, the term "door" should be understood to mean all types of openings that can be closed via a movable closing element, for example 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, bar locks have at least one, but usually several locks.

In order to actuate the locks, an actuation that can be actuated by hand 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, these are kinematically coupled to one another in the case of rod locks via at least one rod, with rod locks with two rods also being widespread. The rods are coupled at one end to the actuator so that the movements of the actuator, which are typically rotary, are translated into axial movement of the rod. The other end of the rod is coupled to the latch so that the axial movements of the rod are translated into movement of a locking element, such as a latch tongue, provided on the latch. Particularly in the case of larger doors, such bar locks are often encountered in which a bar is not only coupled to one lock but to several locks, which results in several locking points and thus a reliable lock, which is the case, for example, in the area of climate chambers, industrial plants, control cabinets etc. can be beneficial. The latches can distributed over the length of the rod and located in particular at the two ends of the rod, but also in intermediate areas.

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

In certain applications, this can lead to dangerous situations, which becomes clear in the example of walk-in climate chambers. Such climatic chambers are characterized by climatic conditions that can be set within a wide range in the interior of the climatic chamber. In order to be able to enter the climatic chamber, a door designed to be climate-tight on the outside is usually provided, which usually has a bar lock equipped with several locking mechanisms. If a person now enters the climatic chamber, it can happen in unfavorable cases that another person closes the door while the person is still inside the climatic chamber. Since the bar lock is operated on the outside of the door, the person locked in the climatic chamber cannot easily unlock the door leaf from the door frame and thus leave the climatic chamber, which under very unfavorable circumstances can even pose a certain risk for life and limb of the imprisoned person.

For this reason are about from 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.

From the DE 44 01 971 A1 a motor-operated rod lock is known in which an emergency release is possible via an energy store designed as a gas spring. In the event of a malfunction of the engine, a locking lever can be actuated using a key, which releases the preloaded gas spring. The rod is moved by the force stored in the gas spring, as a result of which the bolts coupled to the rod can pivot into the open position.

In the EP 1 020 593 A2 a front door is described in which the bolts are actuated by an electric motor and a gear. As soon as the bolts have been moved into the locked position, the motor is switched off and the gear mechanism is decoupled from the locking mechanism. An emergency release is made possible by the fact that the bolts can be moved into the open position by manually turning a knob. A bar lock with an unlocking option that is also suitable as an emergency release from the side opposite the actuation is known, for example, from DD 223 490 A1 known for use in a garage door. In this rod lock, an actuation in the form of a rotary handle is coupled via a rod to a lock in the form of a locking slide. The locking slide can be decoupled from the bar of the bar lock against the force of a spring, which means that the garage door can also be unlocked in an emergency from the inside of the garage door without the actual actuation of the bar lock having to be actuated. In dangerous situations, for example in the event of a fire, the garage door can therefore be opened in an emergency 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 bar and operated manually has proven to be advantageous for bar locks with only one lock, but is not suitable for bar locks with more than two locks. Because for the emergency release 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 at a greater distance from one another.

The object of the present invention is to specify a bar lock which is distinguished by an emergency release which is as it were easy to operate, regardless of the number of locking mechanisms present.

This object is achieved with a rod lock of the type mentioned in that the emergency release is designed in such a way that the rod can be decoupled from the actuation via the emergency release and the lock can be actuated to unlock the door leaf.

The emergency release has a dual function. Firstly, the rod with all the locks coupled to the rod is decoupled from the actuation via the emergency release, with the coupling between the rod and the locks being retained. In addition, the emergency release is also used to operate all locks and thus to unlock the door leaf. In this way, an easy-to-operate emergency release can be provided independently of the number of locks provided on a rod.

Further details and advantages of the invention are indicated with particularity 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. To Once the decoupling has taken place, the rod can be moved and the lock coupled to this can be actuated without this having any effect on the actuation.

In this connection it is of structural advantage if the decoupling device has a decoupling element which can be transferred from a coupling position into 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 by a securing element. In this way, decoupling can take place automatically by removing the securing element. Alternatively, it would of course also be conceivable for the decoupling element to be prestressed in the other direction, ie 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 also 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, which is pretensioned in a direction transverse to the rod, can be released so that it can move automatically into its decoupling position. The result is a simple decoupling of the rod from the actuation.

In this context, it is advantageous to avoid a jerky decoupling if the securing element has an unlocking bevel that runs inclined relative to the rod. In this way, faster or slower decoupling can be achieved depending on the slope angle of the unlocking bevel.

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 actuated in this way.

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

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 relative to the rod along a free-running path. The emergency control can be moved freely in relation to the rod along the free-wheel path. In this range, a movement of the emergency handle does not result in a transmission of the movement to the rod. Only at the end of the freewheeling path is the emergency actuation coupled to the rod and taking it with it via the corresponding driver device.

Advantageously, the movements of the emergency control relative to the rod are guided via an axial guide. This results in a defined movement of the emergency control relative to the rod along the freewheel path.

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

In this context, an advantageous embodiment further provides that the free-running 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 that is fixed to the rod is carried along by the stop that can be moved relative to the rod, and the rod is moved for the purpose of emergency unlocking.

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

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

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

A further embodiment provides that the decoupling device and the emergency actuation interact in such a way that when the emergency release is actuated, first 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 decoupling and actuation can be achieved in a single sequence of movements.

In order to achieve a tight closing of the door, the locks of the bar lock can be designed as rotary clamp locks. By pivoting a locking element of the locking mechanism, not only a form-fitting locking can be effected via the twist-and-clamp fasteners, but also a compression of a door seal provided between the door leaf and the door frame by axially moving the locking element. This means that the door can be closed pressure-tight in the case of air conditioning systems, climate chambers or similar applications.

In this context, constructional advantages are offered by an embodiment in which the locks designed as rotary clamping locks are coupled to the rod of the bar lock via a rod coupling designed as a pivoting lever. The result is a simple and reliable structure, regardless of the number of locking mechanisms that are present.

By designing the rod coupling as a pivoting lever, a structurally simple design of the rod lock can be achieved even with a large number of locks designed as rotary clamp locks. The design of the rod couplings as pivoting levers results in a type of linkage coupling of several locks via a common rod with a structure that is as simple as it is reliable.

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

A constructively advantageous embodiment provides that the joint has a joint pin arranged rotatably within a joint eye. The hinge eye can be designed as a through hole. The joint eye can be arranged on the rod, resulting in a simple construction of the rod. This can be particularly useful in situations where the locking bar needs 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 manufactured in a simple manner by bringing them to the appropriate length and providing them with the appropriate bores.

An embodiment that is advantageous in this context also provides that the joint eye is designed as a slot that accommodates the joint bolt in a displaceable manner. 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 pivoting lever. This can be used for 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 locking mechanism is coupled to the rod via a rod coupling.

A structurally advantageous embodiment provides that the rod coupling is also designed as a pivoting 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 linkage coupling. This results in a structurally particularly simple and reliable structure.

Advantageously, the rod coupling associated with the at least one locking mechanism and/or the rod coupling associated with the actuation form a parallelogram linkage together with the rod.

A further 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 rotational movement and the axial movement of the locking element are advantageously superimposed at least in sections. In this way, the locking mechanism can be actuated with a small operating angle in comparison to a rotary clamping closure, in which these movements take place in movement sections that are separate from one another.

In this context, a further advantageous embodiment provides that the locking angle of the locking element corresponds to the pivoting angle of the rod coupling. For example, the locking element between its open and its locked position by 90 ° pivoted, the required clamping movement can also be achieved immediately by pivoting the rod coupling by 90°.

In this context, it is advantageous if the swivel 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 could arise with a pivoting angle of the rod coupling of 180° and more, are avoided.

A further advantageous embodiment provides that the locking element is designed as a locking tongue or as a rolled tongue. A locking tongue is characterized by its structurally simple, cost-effective design. A roller tongue offers the advantage that it can be used to increase the tensioning movement of the lock in a simple manner. A conical roller can be provided for this purpose.

Furthermore, it is proposed that the lock has a locking shaft that is rotatably and axially movably arranged in a lock housing. The locking element can be firmly connected to the locking shaft at one end of the latter.

A further embodiment provides that the lock has a guideway for converting the rotary movements of the locking shaft into an axial movement of the locking shaft. In this way, a pivoting movement applied to the locking mechanism can be converted into both a rotary and a tensioning movement of the locking element via the rod coupling designed as a pivoting lever. Advantageously, the guide track 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 For example, the axial movement can initially be kept low in a first movement section and then, as soon as the locking element has reached behind the door frame, the axial movement can account for a larger proportion, so that only then does the tensioning movement predominate.

Finally, a further embodiment provides that two guide tracks are provided on opposite sides of the locking shaft. A symmetrical arrangement can be achieved in this way. Canting or the like of the shaft within the housing is not to be feared.

If 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 bar can be converted into a movement of the other bar via the corner drive.

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

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

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

In terms of construction, it is advantageous in this connection if the assembly point is designed as a jointed 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 of the rod is maintained. In this way it is possible for the rod to also be fastened to a certain extent in a translationally movable manner in the region of the mounting point. 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 a slot. 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 moved in rotation.

A particularly advantageous embodiment provides that the mounting element has at least three mounting points, of which two mounting points are of the same design and the third mounting point is of a different design, with the different mounting point being arranged between the mounting points of the same type. 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 mounting elements have a mounting bracket having the mounting points and a guide area for guiding the mounting 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 of the deflection 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 continuous guide area for guiding the deflection element.

A further 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 assembly 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 brackets are arranged offset with respect to the parting plane between the housing halves of the housing. For example, the offset of the mounting brackets relative to the parting plane of the housing halves can correspond to half the thickness of the rod fastened there. In this way, the center plane of the rod is aligned parallel to the parting plane of the housing.

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

In addition, it is proposed in a door of the type mentioned in order to solve the above-mentioned object that it has a bar lock with one or more of the features mentioned above. 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 actuated from the inside when the door is closed.

the 1a) to 1e ) show details of doors 100 with a door leaf 101 arranged pivotably relative to a fixed door frame 102. The door 100 can be a conventional door, for example in the manner of a door that can be walked on by one person, a larger door, for example in the form of a gate, or a smaller door, e.g. in the form of a hatch, flap or similar. In the 1a) to 1e ) shows the closed position of the door 100 in which the door leaf 101 is locked on the door frame 102.

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

According to the design in Fig. 1a ) The actuation 2 can be an actuation 2 that interacts with a tool, for example a square, a triangular or a similar element.

According to the illustration in Fig. 1b ) the actuator 2 can also be a handle, which has the advantage that no additional tool is required to operate the actuator 2. The handle can be designed to be lockable via a lock cylinder. In addition to this simple design of a handle, for example, as shown in the 1c) and 1d ) Also the use of swivel handles as actuation 2 is conceivable, which are first swiveled relative to the plane of the door leaf 101 and then rotated in a next step. Here, too, according to 1c ) locking cylinders or other access control systems, such as an in Fig. 1d ) illustrated fingerprint reader, transponder, card reader or similar systems may be provided. Moreover, the use of lever handles is also appropriate Fig. 1e ) conceivable as actuation 2, which can be gripped and rotated to actuate actuation 2. However, the present rod lock 1 can be used for all types of actuation 2, regardless of the design, which is why the use of something other than the one shown in 1a) to 1e ) shown operations is possible.

In the 2a) to 2c ) such as Figure 3a ) to c) Details of two bar locks 1 viewed from the inside of the door can be seen.

The bar 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 actuation 2 is arranged on the opposite outer side of the door leaf 101 and in the embodiment according to FIG 2a) to 2c ) as a handle and in the design in the 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 actuator 2 is converted into a movement of the rod 4 . The movement of the rod 4 is transferred to the actuation of the locks 3 and thus to a movement of the locking elements 3.1 of the lock 3. 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 rolled tongues.

the 2 and 3 each show bar locks 1 with two locks 3, a lock 3 being arranged above the actuation 2 and a lock 3 being arranged below the actuation 2. However, bar locks 1 with more than two locks 3 are also possible, in order to provide, for example, a three-point, a four-point, a five-point or even more locking point locking of the door leaf 101 on the door frame 102 . Also, according to the illustrations in the Figures 13 to 18 a locking point may be arranged on the top and/or bottom of the door leaf 101, which can also be actuated via a corner drive 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 guide 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 pivoted lever extending between the actuator 2 and the rod 4, see also FIG Fig.8 . About the rod coupling 8, a rotational movement of the actuator 2 is transferred to the axis of actuation B in an axial movement of the rod 4, wherein the rod 4 in the embodiment according to the 2 and 3 also moved a little to the side. One end of the coupling element 8 is non-rotatably connected to the actuator 2 arranged laterally next to the rod 4 . The coupling element 8 follows the rotary movements of the actuator 2. When the actuator 2 is rotated, the coupling element 8 begins to pivot in the manner of a pivoted lever. The other end of the coupling element 8 is articulated on 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 amount of transverse movement of the rod 4 is smaller 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 pivoting lever which extends between the rod 4 and a lock 3 and whose pivoting movements are used to actuate the lock 3 . Details of the rod coupling 9 will be discussed in more 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. At the parallelogram linkage 10 can in addition to the 2 and 3 A total of two locks 3 shown can be connected to further locks 3 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 a seal arranged between the door leaf 101 and the door frame 102 can be an advantage.

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

The movements of the rod 4 designed as a flat rod are guided via rod guides 4.1. The rod guides 4.1 are arranged on the inside of the door leaf 101 and are designed in such a way that they also support the transverse movements resulting from the parallelogram linkage 10 allow the rod 4, cf. 2 and 3 . The rod guides 4.1 therefore have a guide area 4.2 that accommodates the rod 4 and 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, both in the axial and transverse directions, are guided in the guides 4.1.

As the representations of the rod lock 1 in the 2 and 3 this can also be seen, the bar lock 1 has an emergency release 5, via which the door leaf 101 can be unlocked from the door frame 102 in an easy way in emergency situations, for example by a trapped person, regardless of the number of locks 3 present. This is also the case below, in particular with reference to the illustrations in Figures 8 to 12 to be dealt with in more detail.

the Figures 4 to 6 show two versions of a rod lock 1 in different positions of a lock 3. With a) is in each case a first version of the rod lock 1, which is essentially the same as previously shown in 2 corresponds to the embodiment described, and b) designates a second embodiment of the rod lock 1 in each case. With c) lateral views of the rod locks 1 are designated, which do not differ for the two versions.

As shown in the 4a) and 4b ) initially reveal this, the rod locks 1 have a rod 4 designed as a flat rod. A rod coupling 9 is provided in each case for transmitting the movement of the rods 4 to the locks 3 . The rod coupling 9 is designed as a pivoting lever and is assigned to a locking device 3 in each case.

In the area of one lever end 9.1, the rod coupling 9 is connected in an articulated manner to the rod 4 via a joint 20, see in particular FIG Figures 5a) and 5b ). The joint 20 consists of a joint pin 20.1, which is accommodated in an articulated manner within a joint eye 20.2. The other end of the lever 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, as a result of which 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 by welding, for example, 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 articulated eyes 20.2 and connected via a separate articulated bolt 20.1.

The configurations in the 4a), 5a) and 6a ) differ from the configurations in 4b), 5b) and 6b ) characterized in that the joint eye 20.2 is designed as a round hole in the design designated with a) and as a slot in the design designated with b). With the elongated hole solution according to embodiment b), the resulting transverse movements of the rod 4 in the embodiment designated with a) are compensated. For this reason, a rod guide 4.1 can be used in the embodiment according to the statements b), in which the rod 4 is guided only axially. The rod guides 4 therefore have a guide area 4.2 whose width corresponds to the width of the rod 4. FIG. In the case of configurations 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 labeled a) compared to the embodiment labeled b) is that there is significantly less friction, especially with a larger number of locks 3.

As a comparison of 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 pivoting 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 connected to one another in a torque-proof manner. The locking angle α _v of the locking element 3.1 and the swivel 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 pivoting angle α _s of the rod coupling 9 are each 90° between the open and the closed position of the locking element 3.1.

The lock 3 is designed as a rotary clamping lock, which is why the locking element 3.1 is also moved axially in addition to this rotary movement by the locking angle α _v for tensioning a door seal, as is best illustrated in FIGS Figures 4c), 5c) and 6c ) becomes clear.

In Figure 4c ) the locking element 3.1 initially has a larger axial distance A ₁ in relation to the door frame 102. The movement of the rod 4 pivots the rod coupling 9 and with it the locking element 3.1, as can be seen from the comparison with illustrations in 4 with those in figure 5 indicates. 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. As the comparison of the representation in the 4c) and 5c ) shows 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 ) reduced.

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 6 shown closed position is reached. In this position, the locking element 3.1 rests against the door frame 102 and tightens 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 according to FIG Figure 7a ) to recognize.

The lock 3 is connected at one end to the rod coupling 9 designed as a pivoting lever. The rod coupling 9 is rotatably coupled with one lever end 9.1 to a locking shaft 3.2 of the lock 3, but is coupled in an axially movable manner. For this purpose, the locking shaft 3.2 is guided in an axially movable manner in a locking housing 3.1. The rotational movements, which are applied to the locking shaft 3.2 via the rod coupling 9, are carried out via two guideways 3.4 arranged on opposite sides of the locking shaft 3.2 and a guide element 3.5 engaging in the guideway 3.4, which is designed in the manner of a bolt and is arranged on the movable locking shaft 3.2 is converted into an axial movement along the locking axis V. In this way, a turning-clamping movement of the locking element 3.1 arranged at the other end of the locking mechanism 3 takes place. The locking element 3.1 is firmly connected to the shaft 3.2. The locking element 3.1 can be connected to the shaft 3.2 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 prestressed.

As the Figure 7b ) illustrates this, an actuation 50 could also be used instead of the rod coupling 9, which would result in a turn-buckle closure that can be used not only on a rod closure 1, but alternatively also as a one-point locking device in the manner of a sash fastener. For use in the rod lock 1, the rod coupling 9 would have to be connected to the actuation 50 in the region of an actuation 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 one-point lock in the manner of a sash fastener.

Figure 7c ) finally shows a locking element 3.1 designed as a rolling tongue. The locking element 3.1 according to Figure 7c ) can alternatively to the locking element designed as a tongue according to 3.1 Figure 7a ) are arranged on the locking shaft 3.2. By using the locking element 3.1 designed as a rolling tongue, a greater axial clamping distance can be achieved, see also the illustration in 3 .

Based on the illustrations 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 ) shows the area of actuation 2 of the rod lock 1 in an enlarged view. Figure 8a ) shows the rod lock 1 in the closed state, Figure 8b ) shows the open state. To remove the closure 1 from the in Figure 8a ) shown in the position shown in Figure 8b ) To convert the position shown, the actuation 2 is gripped by hand and turned by 90°. Corresponding to the rotational movement of the actuator 2, the rod coupling 8 also begins to pivot through 90°, as a result of which the locks 3 provided on the rod closure 1 are actuated in the manner described above.

As the comparison between the 8a) and 8b ) shows that 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 that can be actuated as an alternative to the actuation 2 in emergency situations. 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, via 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 of the rod 4 from the actuator 2 and the actuation of the locks 3 can be accomplished with just one hand. To do this, the emergency release 5 must be gripped by hand and moved along the arrow P provided on the emergency release 5. The displaceable parts of the emergency release 5 have a signal color, for example red, orange or a similar color, so that operation is intuitive even under poor visibility conditions.

9 shows one of the representation in Figure 8a ) Corresponding view of the bar 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 9 shown position forms the bolt-like decoupling element 6.1 together with the Recording 8.1 an articulated connection of the rod coupling 8 with the rod 4 according to the functionality previously described 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 actuating axis of the actuating element 2 and is non-rotatably connected thereto. The decoupling element 6.1 is designed as a spring bolt. The decoupling element 6.1 has a bolt 6.1.1 which is preloaded by a spring 6.1.2 in the direction of the decoupling position. In 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 in the rod 4, cf Figure 10d ). This results in an articulated plug-in connection 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 by the securing element 6.2. At its end facing away from the rod 4, the decoupling element 6.1 has a bolt head 6.1.3 which is designed in the manner of a radial thickening and which dips into a securing receptacle 6.2.2 of the securing element 6.2.

In the area of the rod 4, the emergency actuation device 7 has a driving device 7.1. The driving device 7.1 has a slot 7.1.1 extending in the direction of the rod 4, the end regions of which form stops 7.1.2, which interact with a stop 7.1.3 arranged fixedly on the rod 4. The rod-fixed stop 4 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 control 7 relative to the rod 4, the emergency control 5 also has an axial guide 7.2 in which the rod 4 is accommodated. 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 section receiving the rod 4 . In addition, the emergency control 7 has a handle 7.3, which of 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 functioning of the emergency release 5 is based on the representations in the 10a) to 10d ) are explained.

Figure 10a ) shows the locked position of the rod lock 1 as shown in 9 . In this position, the rod 4 is kinematically coupled to the actuator 2 via the rod coupling 8 . Movements of the actuator 2 are as shown in the 8a) and 8b ) is 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 control 7 is gripped and moved in the direction of the arrow P opposite 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 activated first. The decoupling element 6.1 emerges from the safety receptacle 6.2.2 of the safety element 6.2 and, due to the preload of the spring 6.1.2, moves 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 suddenly, but slides along an unlocking 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 actuator 2, see also the illustration 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, the driving device 7.1 moves, guided by its axial guide 7.2, relative to the rod 4. The driver device 7.1 is moved along a freewheel path F according to the length of the elongated hole 7.1.1 relative to the stop 7.1.3 formed fixedly on the rod 4 until it comes into contact with the stop 7.1.2. This position at the end of 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, control 2 can be turned without affecting the position of the rod. In addition, the movable stop 7.1.3 and the fixed stop 7.1.2 are in contact with one another, so that when the emergency release 5 moves further along the arrow P, the driving device 1 now takes the rod 4 with it. this is in Figure 10d ) illustrated.

According to the illustration 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 actuator 2 compared to the illustration in FIG Figure 10c ) can be recognized. In this position, the rod 4 was moved so far that the locks 3 were actuated and the door panel 101 was unlocked from the door frame 102 . The axial travel of the rod 4 corresponds to that in FIG 8a) and 8b ) shown traverse path.

In order to separate the unlocking and the entrainment process from one another in terms of time, the free-wheeling 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 locks 3 are actuated in a second movement segment via the emergency actuation 7 .

By actuating the emergency release 5, a reliable and easy-to-use unlocking of the door leaf 101 in emergency situations can be achieved in this way with just one hand. The emergency release 5 performs a kind of dual function in that it ensures, via the decoupling device 6 , that the actuation 2 is decoupled from the rod and that the locks 3 are actuated by movement of the rod 4 . The emergency release 5 is therefore equally applicable regardless of the number of existing locks 3 for different types of bar locks 1.

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

The emergency release 5 as shown in the 11 and 12 is designed in contrast to the emergency release 5 described above as a two-hand operation. A bolt 6.1.1 preloaded by a spring 6.1.2 serves as the decoupling device 6 . However, the bolt 6.1.1 is not biased by the spring 6.1.2 in the direction of the decoupling position, 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 by 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 configuration, the emergency actuation device 7 is designed as a driver device 7.1 that is 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 to move the entrainment device 7.1.

To operate the emergency release 5 according to the 11 and 12 it is therefore necessary for the operator to first pull the spring bolt 6.1.1 out of the opening 4.3 of the rod 4 in order to release the rod 4 from the actuation 2 to be kinematically decoupled. In a next step, holding the bolt 6.1.1 in this position, the driver device 7.1 is gripped by its handle 12 with the second hand and the rod is moved. This results in an actuation of all locks 3 connected to the rod 4. This also allows rod locks 1 to be unlocked in an emergency, regardless 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 embodiment according to Figures 8 to 10 is that both hands of the operator are required to unlock the door panel 101.

Below are details of a corner guide 30 based on the illustrations in FIGS Figures 13 to 18 be explained.

13 shows first a bar lock 1, which is provided with two corner deflections 30. the inside 13 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 guides 30 are used to move the in accordance with the embodiment 13 along a vertical edge of the door leaf 101 extending rod 4 to the rods 14 arranged transversely thereto. 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 agree in all details with the locks 3 previously described. Likewise the coupling of the rod 4 via the rod couplings 9 with the locks 3 as well as the rod coupling 8 for coupling the rod 4 with the confirmation 2.

The functionality of the corner drive 30 can best be explained using the illustrations in 14 recognize. The corner guide 30 has an overall angular geometry, with the two legs of the angle being angled at 90° to one another. 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 via the actuation 2 and moves in the illustration in FIG 14a ) downward. This movement is transmitted to the latches 3 via the rod couplings 9 . The corner guide 30 is provided so that the movement of the rod 4 can also be transmitted to the rod 14 and from this to the locking device 3 via the rod coupling 9 provided there. The end of the rod 4 is connected to a mounting element 40 of the corner guide 30 . The rod 14 is also connected at one end to a mounting element 40 of the corner guide 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 .

As the comparison of the representation in the Fig. 14a) and 14b) shows, the movement of the rod 4 is also transmitted to the rod 14 via the corner guide 30 and deflected at a right angle 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, 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. 15 shows a perspective view of the lower housing half 34 with the in this deflection element 31 is accommodated such that it can be slid in two directions. The deflection element 31 can be a flexible element that transmits both tensile and compressive forces. In the exemplary embodiment, the deflection element is a flexible metal strip made of spring steel. The deflection element 31 is guided within a rail-like guide 35 of the housing 32 . The deflection element 31 has mounting elements 40 at its ends. The two assembly elements 40 at the ends of the deflection element 31 are of identical construction. 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 . Like the deflection element 31 , the guide area 44 is guided in the guide 35 of the housing 32 . As shown in 17 can be seen, the guide 35 has a guide area 35.1 for this purpose, 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 deflection element 31 is guided. The guide area 35.2 extends continuously over the entire length of the corner guide 30. The guide area 35.1 is interrupted in the area of the corner of the angular corner guide 32.

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

In the embodiment according to 13 for example, the rod 4 is moved essentially in the longitudinal direction of the rod, with this also performing certain transverse movements due to the linkage coupling designed as a parallelogram linkage 10 . In order to enable these transverse movements, one of the mounting points 42 is designed as a slot. Translational movements of the rod 4 are therefore permitted within the mounting point 42 designed as a slot. In contrast to the rod 4 takes place in the case of the rod 14, during the actuation of the rod lock 1, a certain pivotal movement. For this reason, the rod 14 is fastened in a mounting point 41, which is designed as a hinge eye and allows rotary movements of the rod 14.

The assembly point 42 is characterized in that a translational degree of freedom of the rod 4 fastened to it is retained. The assembly point 41 is characterized in that a rotational degree of freedom of the rod 14 connected to it is retained.

In the exemplary embodiment, two mounting points 41 designed in the manner of a joint eye and one mounting point 42 designed in the manner of an elongated hole are provided. Two mounting points 41 of the same type and one mounting point 42 of a different type are therefore provided. The different mounting point 42 is located between the mounting points 41 of the same type. The arrangement is chosen symmetrically such that, regardless of the orientation of the corner drive 30, either one of the mounting points 41 and the mounting point 42 can always be occupied. The corner drive 30 can therefore be used with a bar lock 1 as shown in 13 be used both as an upper corner drive 30 and as a lower corner drive 30.

For the symmetrical introduction of forces into the corner drive 30 , the mounting bracket 43 is arranged asymmetrically with respect to the guide area 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 designed as flat rods. In this way, the center plane of the rods 4, 14 is aligned with the parting plane T of the housing 42. This results in a favorable introduction of force .

The assembly of the corner drives 30 on the door leaf 101 of the door 100 is to be based on the representation in FIGS 18 be 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 angled corner drive 30 can be aligned with its fastening bores 45 relative to the welding stud 46 and plugged onto it. Since the welding studs 46 have a radial widening at their door-side end, the fastening bores 45 have a clearance that accommodates the radial widening in the assembled state. Undesirable 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 avoided in this way.

After the corner drive 30 has been put on and secured using appropriate securing elements, the rods 4, 14 can be connected to the appropriate assembly points 41, 42.

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

The bar locks 1 described above are distinguished by a particularly advantageous emergency release 5 . Further advantages of the bar locks 1 result from the design of the locks 3 as twist and turn locks, through which a door seal can be tightened at several points, and their structurally simple and reliable coupling to the bar 4 via bar couplings 9 designed as pivoting levers The corner guide 30 that can be used with the rod locks 1 allows a flexible connection of different rods 4, 14.
