Description

The invention relates to a locking device for a door with a frame assembly element, a door assembly element and a locking lever connecting the two assembly elements for locking the door in its open position.

In various areas of technology, there is a need to determine doors, which includes not only doors in the actual sense, but also flaps, hatches, covers or windows, in their open position and to secure them in the open position, see above that the doors cannot slam shut of their own accord or be closed unintentionally. Locking devices are usually used for this used, which can lock the doors in the open position.

These latches often include a latch lever connected on one side to a door mount mounted on the door and on the other side to a frame mount mounted on the door frame. A relative movement of the two assembly elements can then be prevented via the locking lever in a corresponding locking position, so that the door is locked in its open position.

Although such structurally quite simply designed locking devices have proven themselves in practice for many years, they can only be used for doors hinged on one side, ie for doors that can only be moved about a single pivot axis.

A distinction is typically made between doors hinged on one side, doors hinged on the left and doors hinged on the right. For doors hinged on the left, the pivot axis is located on the left from the perspective of a person looking at the opening surface of the door, i.e. the surface that lies on the side to which the door opens, and on the right for doors hinged on the right. Although such doors hinged on one side are the normal case, there are also doors that are hinged on both sides and in this respect can be opened either to the right about a right pivot axis or to the left about a left pivot axis. In this respect, these doors can also be moved not only into one open position, but into two different open positions, namely a left-hand and a right-hand open position.

In order to open a door both to the left and to the right, no simple hinges can be used, but in practice so-called hinge locks are often used for this purpose. These hinged latches combine the functions of latches and hinges, allowing the door to be opened to the left as well as to the right. The more precise design and functioning of such hinged closures are, for example, in DE 10 2015 117 505 B3 described in more detail.

The locking devices described above are not suitable for doors that are hinged on both sides. Although these can usually be used for both right-hand and left-hand doors due to different assembly, they cannot be used for doors hinged on both sides, which can be opened both to the right about a right-hand pivot axis and to the left about a left-hand pivot axis. The range of uses of such locking devices is therefore limited.

Proceeding from this, the invention sets itself the task of specifying a locking device which is characterized by an expanded range of uses and which can also be used in particular for doors hinged on both sides.

This object is achieved by a locking device which has the features defined in claim 1. Advantageous developments are specified in the dependent claims.

The fact that the frame assembly element and the door assembly element each have two locking contours in which the locking lever can be locked creates the possibility that doors hinged on both sides can be locked not only on one side. The door can insofar both in the right open position as well as in the left openness can be determined. The right hand open position is the open position to which the door moves when opening when the pivot axis is on the right side as viewed from the opening face, and the left hand open position is equivalent to the open position to which the door moves when opening when the pivot axis is on the left when looking at the opening face.

Furthermore, it has proven to be advantageous if the locking lever can be moved into a right locking position and into a left locking position as a result of the movement of the door. In this respect, the locking lever does not have to be locked manually or by an additional drive with the locking contours, but through the movement of the door, the locking lever can basically automatically be brought into the corresponding left or right locking position when the door is moved into the left open position or into the right open position will. A separate movement of the locking lever, e.g. into one of the two locking contours, is therefore not necessary. Rather, the locking lever can be positively coupled to the movement of the door.

In this respect, the locking lever can be designed as a changeover lever and can lock a door hinged on both sides both in the left-hand open position and in the right-hand open position.

With regard to the two locking contours, it has proven to be advantageous if a locking contour of the frame assembly element and a locking contour of the door assembly element are assigned to the right open position of the door and the other locking contour of the frame assembly element and the other locking contour of the door assembly element are assigned to the left open position. In this respect, one of the two locking contours of a mounting element can in each case engage with the corresponding locking contour of the other mounting element together form a pair of locking contours, namely one associated with the right-hand open position of the door and one associated with the left-hand open position of the door. The door can then be locked in the left open position in that the locking lever or its two end regions are arranged in the locking contours of the pair of locking contours associated with the left open position. The same can apply to the right-hand open position or the right-hand pair of locking contours.

In this respect, the two left-hand locking contours of the two assembly elements can form a left-hand locking contour pair and the two right-hand locking contours of the assembly elements can form a right-hand locking contour pair.

It has also proven to be advantageous if the locking lever can be moved into the locking contours associated with the corresponding open position by moving the door either into the left open position or into the right open position, in particular independently. The locking lever can thus be coupled to the door in such a way that it is moved through the door and is automatically moved into the correct locking contours. The locking lever can thus only determine the door in a specific open position in each locking contour. When the door is moved into one of the two open positions, the locking lever can be moved in the direction of the assigned locking contours, so that the locking lever is always arranged in the correct or assigned locking contours and reliable locking is also ensured for doors hinged on both sides. When the door reaches the corresponding open position, the locking lever can also reach the locking contours assigned to the open position.

In terms of construction, it has proven to be advantageous if the two locking contours of the frame assembly element and the two locking contours of the door assembly element are each connected to one another via a guide. The locking lever can thus be moved back and forth between the two locking contours of the frame assembly element via the guidance of the frame assembly element and the locking lever can be moved back and forth between the two locking contours of the door assembly element by guiding the door assembly element. Each of the four locking contours can represent an end area of a guide, so that the guides are each delimited by two locking contours.

It is advantageous if the locking lever in its locking positions encloses an angle in the range between 150 degrees and 180 degrees, preferably between 160 degrees and 180 degrees, particularly between 170 and 180 degrees, with the guide of the door assembly element. With this configuration, it does not reduce or impair the passage through the door opening, or only to a very small extent, since it is basically arranged to the side of the door opening in every open position. However, the angle between the guide of the frame assembly element and the locking lever can be slightly more than 90 degrees in the open position. The angle is preferably between 90 degrees and 120 degrees, particularly preferably between 90 degrees and 110 degrees and very particularly preferably between 90 degrees and 100 degrees.

Furthermore, it has proven to be advantageous if the locking lever can be locked independently in the locking contours. If the locking lever is moved by a movement in the guides in such a way that it arrives at one end of one of the guides, the locking lever can then be automatically locked in the corresponding locking contour. Active intervention is not necessary in this respect, but The locking lever is then automatically locked in the correspondingly assigned locking contours when one of the open positions is reached.

With regard to the two assembly elements, it has also proven to be advantageous if the door assembly element and the frame assembly element are designed as identical parts. This offers advantages in the manufacture of the locking device and also in the costs of production and also simplifies assembly.

It has also turned out to be advantageous if the two guides are designed as linear guides in which the locking lever can slide back and forth. The locking lever or the end areas of the locking lever can be moved back and forth on straight trajectories between the locking contours. The movement of the locking lever in both guides can be positively guided by a movement of the door, so that it is not necessary to actively, e.g. manually, close the locking lever depending on whether the door is to be moved about a right or left pivot axis move.

With regard to the attachment of the locking lever to the frame assembly element and the door assembly element, it has proven to be advantageous if the locking lever is hooked into the two guides. For this purpose, the locking lever can be connected to the guide or guided in the guide via guide elements, for example. A solution to the connection between the locking lever and the mounting element then requires a solution to the guide elements. In this context, hooking in does not necessarily mean that the locking lever is hooked in loosely. By hooking a movement of the locking lever in the guides and thus relative to the two mounting elements is made possible. That Frame mounting element can thus be connected to the door mounting element via the locking lever.

According to an advantageous development of the invention, it is proposed that the locking lever be hooked into the two guides from different directions. The locking lever can, for example, be hooked into the door assembly element from below and into the frame assembly element from above. In the vertical direction, the locking lever can be arranged between the two assembly elements.

To connect the locking lever to the two assembly elements, it has proven to be advantageous if the locking lever has a guide element in each of its opposite end regions, with one of the guide elements being guided in the guide of the door assembly element and the other guide element being guided in the guide of the frame assembly element. A reliable connection between the locking lever and the two mounting elements or the corresponding guides can be achieved by the guide elements. The guide elements can be guided in the guides of the assembly elements in the manner of slot nuts, so that a reliable back and forth movement can be achieved when the door is moved.

With regard to the locking lever, it has proven to be advantageous if it has a connecting area arranged between the guide elements. The two guide elements can be firmly connected to one another via the connection area. The connection area can be designed in the form of a flat bar or rod, so that the guide element can have an elongate shape overall.

In a further development of the guide elements, it has proven to be advantageous if they are designed in the form of pegs. The guiding elements can in this respect be designed to project perpendicularly from the connection area. It is advantageous if one guide element projects upwards and one guide element downwards, so that the guide element projecting upwards can then be guided in the guide of the door assembly element and the guide element projecting downwards can be guided in the guide of the frame assembly element. The guide elements can be fixed, but also rotatably connected to the connection area of the locking lever.

With regard to the guide elements, it has proven to be advantageous if they each have a guide area and a locking area, with the diameter of the guide area being smaller than the diameter of the locking area. With this configuration, the guide elements can be secured both in the locking contours and also be guided in the guide. Due to the smaller diameter, the guide element can be reliably moved back and forth in the guide and a movement perpendicular thereto can be prevented. The guide elements can thus be reliably held in the guide. In this respect, the guide region can be designed as a constriction and extend around the circumference of the guide element in the manner of a groove. In terms of construction, the guide elements can be designed, for example, as stepped sleeves, which can be connected to the connecting area of the locking lever, for example, via a screw connection. The length of the guide elements or the length of the stepped sleeve must be measured in such a way that they can be raised far enough by the locking lever touching the guide ramp to be unlocked by this vertical movement.

In order to achieve a reliable locking of the locking lever or the guide elements, it has proven to be advantageous if the guide elements automatically lock the door when it is reached automatically lock one of the locking contours with it. If the door is thus moved into one of the two open positions, the guide elements can lock independently in the two locking contours assigned to the respective open position of the door. The locking can be driven by gravity, so that the guide elements are automatically secured in the locking contours when they reach the locking contours due to the force of gravity from the guide.

Furthermore, it has proven to be advantageous if a locked guide element is rotatably mounted in the locking contour. The locking contours can function as pivot bearings in which the locking lever or the corresponding guide elements are rotatably mounted. When a guide element is locked, it is then no longer linearly movable in that it cannot be moved back into the guide, but it is still rotatable. The locking lever can be rotated about the corresponding guide element insofar as its other guide element is not locked but can still be moved back and forth in the other guide. It is only when the other guide element also reaches a locking contour that movement of the guide element is no longer possible, as a result of which the door can then no longer be moved but is correspondingly fixed.

In a further development of the invention, it is proposed that the guide elements can be unlocked, in particular by lifting them. Since the guide elements can be locked in the respective locking contour by gravity, they can also be unlocked again accordingly by a force directed against gravity. The guide elements can thus be movably mounted in the locking contours in the axial direction. By lifting the guide element to be unlocked, it can be moved in the axial direction in the locking contour. If the guide element is raised so far until the Guide section is level with the guide, the guide element can be transferred from the locking contour into the guide. The corresponding guide element is then no longer locked but can be moved in the guide.

With regard to unlocking, it has proven to be advantageous if the guide element guided in the guide of the door assembly element can be unlocked manually in the locked position. For unlocking, the guide element can be raised by hand, for example, so unlocked. The possibility of unlocking the guide element by hand means that the door can also be unlocked again by hand. It may be sufficient if the guide element of the door assembly element is unlocked, since this can then be moved back and forth in the guide of the door assembly element and the door can be moved again accordingly. The other guide element can initially remain in the locked position. Since the locking lever is rotatably mounted in the corresponding locking contour, it does not impede movement of the door.

The guide element arranged in the locking contour of the frame assembly element can be unlocked automatically when the door is closed. When the door is closed, both guide elements can be unlocked. This ensures that the door can also be moved from the closed position either around the left or right pivot axis into the corresponding open position and the guide elements then automatically move in the respective guides towards the associated locking contours when the door is opened.

With regard to the guide and the locking contour, it has proven to be advantageous if the guide is designed in the manner of an elongated hole. The guide can have a constant width. The diameter the guide can correspond approximately to the width of the guide areas. The locking contours could be designed as bores and these can have a larger diameter than the width of the guide. The diameter of the locking area of the guide element can correspond approximately to the diameter of the locking contour. When it reaches one of the locking contours, the guide element can fall, driven by gravity and thus independently, into the respective locking contour and lock with it.

With regard to the guide element guided in the guide of the frame assembly element, it has proven to be advantageous if this can be unlocked by a closing movement of the door. It is therefore not necessary to actively unlock this guide element, for example by hand, but it can be unlocked automatically by the closing movement of the door.

In a further development of the invention, it has proven to be advantageous if the frame assembly element has a guide ramp against which the locking lever can run when the door is closed in such a way that the guide element is automatically unlocked. The guide element guided in the frame assembly element can be lifted by the guide ramp when the door is closed and thus unlocked independently. The guide ramp can be arranged parallel to the guide of the frame mounting element. When the door is closed, one side of the locking lever can be rotatably secured in one of the two locking contours of the frame mounting element and thus be rotatably mounted. The other guide member may be reciprocally movable in the guide of the door mounting member. Closing the door thus allows the locking lever to pivot about the secured guide member, where it may come into contact with the guide ramp. By approaching the ramp, the corresponding guide element can be raised and thus independently be unlocked. The guide ramp can be designed symmetrically, so that the unlocking process is independent of whether the door is closed starting from the right-hand open position or from the left-hand open position. Furthermore, the guide ramp can also ensure that the locking lever moves in the direction of the correct or corresponding open position of the associated locking contours when the door is opened. In this respect, the guide ramp can have a dual function.

Furthermore, it is also possible that two guide ramps are provided. These can be arranged side by side. In this respect, one guide ramp can then be assigned to the right locking contours or the corresponding locking contour pair and the other guide ramp to the left locking contours or the left locking contour pair. By using two guide ramps, an adjustment to different door widths can also be achieved. Because the two ramps can thus be positioned independently of each other and adapted to the structural conditions of the locking device. The height of the guide ramp or ramps can be adapted to the height of the guide element so that it is raised sufficiently far to be able to move the guide element out of the locking contour into the guide. In one embodiment, the guide ramp can also be integrated into the guide or into the locking contour, for example, so that the guide element is automatically unlocked when the door is moved.

With regard to the guide ramp, it has also proven to be advantageous if it has two run-up slopes and a plateau region arranged between the two run-up slopes. When the door is closed, starting from the right-hand open position, the locking lever can run against the right-hand run-on slope and when the door is closed, starting from the left-hand open position, on the left-hand run-on slope. Corresponding If two guide ramps are used, the guide lever can also run up against the run-on bevels, which face the locking contours assigned to the respective open position. Reliable unlocking can be achieved with this configuration, regardless of whether the door is moved about the right-hand or left-hand pivot axis. Depending on whether the door is moved about the left or the right pivot axis, the locking lever or the connecting area of the locking lever can run up against one of the two contact slopes when the door is closed. In this respect, each contact slope is associated with one of the two locking contours of the frame fastening element. The plateau area can extend essentially parallel to the guide of the frame fastening element, but it can be arranged higher than the guide due to the bevels.

With regard to the two fastening elements, it has also proven to be advantageous if the frame fastening element and the door fastening element are designed as an angle or as a U-profile with a guide leg and a fastening leg, with the guide and the locking contours each being arranged on the guide leg and the fastening elements can be connected to the door or the door frame via the fastening leg. The mounting elements can be screwed to the inside of the door and the frame in a detachable manner, for example using screws, via the fastening leg. The angle or the inner angles of the U-profile can be one or two right angles. The two guides or the two guide legs can be aligned parallel to one another and perpendicular to the door surface. The guide ramp can be arranged in particular on the guide leg. The two mounting elements can be made of metal, the guide and the locking contours can be drilled or milled into the mounting elements.

The arrangement of the mounting elements described above can also be reversed. Correspondingly, the door mounting element can also be arranged on the door frame and the frame mounting element can also be arranged on the door.

With regard to the object mentioned above, a door and a door frame are also proposed, the door being hinged to the door frame on both sides and a locking device for locking the door in its left open position and in its right open position. The door can thus be locked in both open stables by the locking device. The locking device is advantageously designed in the manner described above.

Further advantages and developments are to be described in more detail below with reference to the attached drawing of an exemplary embodiment of the invention. Show in it:

The representations of Figures 1a and 1b show a door 20 which is connected to a door frame 30 via four hinge locks 40 . The hinged closures 40 have a dual function, because they can act both as a lock and as a hinge, so that the door 20 can be moved not only about a single pivot axis, as is usual with normal doors 20, but about two pivot axes. Consequently, the door 20 in two different open positions, namely in a left open position OL in the Fig. 1a is shown, and in a right open position OR, which is in the Fig. 1b is shown to be moved.

In order to prevent the door 20 from being closed unintentionally or closing again after opening, a locking device 10 is provided, which is arranged in the area of the interior space to be closed, so that the locking device 10 is covered by the closed door 20 and thus from is not visible outside. The door 30 can be locked in the right-hand open position OR as well as in the left-hand open position OL via the locking device 10 without the locking device 10 having to be adjusted or moved manually for this purpose. Rather, the locking device 10 is designed such that it basically automatically adapts to whether the door 30 is moved about the left or the right pivot axis, so that it can reliably lock the door 30 in both open positions OL, OR. The more precise structural design of the locking device 10 and the function of the individual components will now be based on the Figures 2a, 2b and 3a, 3b be described in more detail.

the Figures 2a and 2b show the door 20 attached to the door frame 30 via the hinge locks 40 in a sectional plan view, once in the left open position OL and once in the right open position OR. The locking device 10 essentially consists of three main components, namely a door mounting element 2 arranged centrally on the inside of the door 20, and a door mounting element 2 arranged on the frame side and also centrally Frame mounting element 3 and a locking lever 1, which connects the two mounting elements 2, 3 together.

The frame mounting element 3 and the door mounting element 2 are designed as identical parts, so that their structure will be described together below. Both mounting elements 2, 3 have a U-shaped cross section, as is the case with the illustrations of FIG Figures 3a and 3b is evident. One leg of the profile is designed as a guide leg 2.3, 3.3 and is provided with a guide 2.3 or 3.3. The two guide legs 2.3, 3.3 of the two assembly elements 2, 3 are arranged parallel to one another and perpendicular to the surface of the door 20. At the ends of the guides 2.1, 3.1, these are each connected to a locking contour 2.2a, 2.2b, 3.2a, 3.b, the function of which will be described in more detail below. Furthermore, both assembly elements 2, 3 have a fastening leg 2.4, 3.4, via which the assembly elements 2, 3 can be arranged on the door 20 or on the door frame 30, for example via a screw connection.

The locking lever 1 has an elongate, compartmental shape and is connected in each of its two end regions to a guide element 1.1, 1.2. The guide element 1.1 is guided in the guide 2.1 of the door mounting element 2 and the other guide element 1.2 in the guide 3.1 of the frame mounting element 3, so that the locking lever 1 connects the two mounting elements 2, 3 to one another accordingly.

If the door 20 is now closed, the two mounting elements 2, 3 are basically arranged parallel to one another and are in alignment due to their central arrangement. Due to the small distance between the two mounting elements 2, 3, the locking lever 1 closes an acute angle with the two mounting elements 2, 3 or with its guides 2.1, 3.1 a. If the door 20 is now moved from this closed position about the left pivot axis and into the left open position OL according to FIG Figure 2a spent, migrate due to the pivoting movement of the door 20, the two ends of the locking lever 1 in the two guides 2.1, 3.1 to the left in the direction of the left locking contours 2.2a and 3.2a. When the door 20 is in the left open position OF, the two guide elements 1.1, 1.2 have also reached the end areas of the guides 2.1, 3.1 or the two left locking contours 2.2a and 3.2a. In this position, the locking lever 1 is then in the left locking position FL and the door 20 is fixed in its left open position OL and can no longer be closed. The two left locking contours 2.2a and 3.2a together form a left locking contour pair and the locking lever 1 clamps in this position between the two mounting elements 2, 3 and thus prevents a relative movement of the mounting elements 2, 3 and thus also a closing movement of the door 20.

When the guide elements 1.1, 1.2 reach the end areas of the guides 2.1, 3.1, they are automatically locked in the corresponding locking contours 2.2a, 2.2b, 3.2a, 3.2b, so that no intervention is required for locking, but the locking device 10 in Basically self-locking is designed. This automatic self-locking results from the design of the guide elements 1.1, 1.2, the guides 2.1, 3.1 and the locking contours 2.2a, 2.2b, 3.2a, 3.2b. The locking contours 2.2a, 2.2b, 3.2a, 3.2b are designed as bores and these have a larger diameter than the width of the guides 2.1, 3.1, as is particularly the case in Figures 3a and 3b can be seen. The guide elements 1.1, 1.2 have a peg-like shape and, in the simplest case, can be designed as helical elements that can be connected to the end areas of the connection area 1.3 of the locking lever 1.

The guide elements 1.1, 1.2 have a locking area 1.12, 1.22 and a guide area 1.11, 1.21 arranged above the locking area 1.12, 1.22, the guide area 1.11, 1.21 having a smaller diameter than the locking area 1.12, 1.22. As a result, only the guide area 1.11, 1.21 fits into the guides 2.1, 3.1, but not the locking area 1.12, 1.22. The guide element 1.1, 1.2 can now be moved back and forth in the linear direction via the corresponding guide area 1.11, 1.21 by the movement of the door 20 in the guide 2.1, 3.1. When the guide element 1.2, 1.2 reaches one of the locking contours 2.2a, 2.2b, 3.2a, 3.2b, it basically falls, driven by gravity, from the guide 1.1, 1.2 into the locking contours 2.2a, 2.2b, 3.2a, 3.2b. In this locked position, the guide area 1.11, 1.21 is then arranged in a plane below the guide 1.1, 1.2 and the comparatively larger locking area 1.12, 1.22 at the level of the guide 1.1, 1.2. However, since the locking area 1.12, 1.22 does not fit into the guide 1.1, 1.2, the guide element 1.1, 1.2 is then secured in the locking contour 2.2a, 2.2b, 3.2a, 3.2b and can no longer be moved back into the guide 1.1, 1.2 will. Rather, the locking contour 2.2a, 2.2b, 3.2a, 3.2b acts as a pivot bearing for the locking lever 1 or the guide elements 1.1, 1.2, which allows a rotary movement but prevents a linear movement.

If the door 20 is thus moved about the left-hand pivot axis and is moved into the left-hand open position OL, the left-hand locking contours 3.2a, 2.2a assigned to the two guide elements 1.1, 1.2 in their corresponding open positions OL are automatically locked, so that the door 20 then cannot moved further or cannot be closed again.

In order to close the door 20 again, the lock of at least one of the two guide elements 1.1, 1.2 must first be unlocked again.

The guide elements 1.1, 1.2 can be moved in the axial direction in the locking contours 2.2a, 2.2b, 3.2a, 3.2b, basically in two different positions or in two different planes. Namely, in a locked position, the locking area 1.12, 1.22 is at the level of the guides 1.1, 1.2 and in a raised and unlocked position, the guide area 1.11, 1.21 is at the level of the guide 1.1, 1.2 and the guide element 1.1, 1.2 can therefore only be moved in this position in the guide 2.1, 3.1.

To now according to the representation of Figure 2a To unlock the door-side guide element 1.1 and the left locking contour 2.2a, the guide element 1.1 must be raised slightly by hand until the corresponding guide area 1.12 is arranged at the level of the guide 2.1. When the door 20 moves, the guide element 1.1 can then slide in the guide 2.1 in the direction of the right-hand locking contour 2.2b. The guide element 1.2 initially remains locked and thus acts as a pivot bearing for the locking lever 1. This is then rotatably mounted on one side in the locking contour 3.2a and on the other side linearly movable in the guide 2.1.

How to use the Figure 3b can imagine, when the door 20 is closed, the locking lever 1 or the connecting area 1.3 comes into contact with the left-hand guide ramp 4 from a certain angle. This is arranged parallel to the guide 3.1 of the frame assembly element 3 and basically consists of three parts, namely two chamfers 4.1, 4.2 and a plateau area 4.3 arranged between the two chamfers. If the locking lever 1 now comes into contact with the left starting bevel 4.1 of the left guide ramp 4, the locking lever 1 is thereby moved slightly upwards. This has the effect that the guide element 1.2 still secured in the locking contour 3.2b is unlocked, so that after the unlocking it can also move in the guide 3.1 can slide right in the direction of the other locking contour 3.2a. If the door 20 is then closed, both guide elements 1.1, 1.2 are unlocked.

If the door 20 is then starting from the closed position as shown in FIG Figure 2b moves around the right pivot axis, the locking lever 1 or its two guide elements 1.1, 1.2 moves, in the same way as was described above for a movement around a left pivot axis, in the direction of the two right locking contours 2.2b, 3.2b. When the guide elements 1.1, 1.2 then reach the two locking contours 3.2b and 2.2b assigned to the left open position OF, they are automatically locked with them again and the guide lever 1 is then correspondingly in the right locking position FR, as is shown in FIG Figure 2b can be seen. In order to close the door 20 again, the guide element 1.1 arranged in the door mounting element 2 must first be lifted slightly again for unlocking, so that the door 20 can be moved. The unlocking of the guide element 1.2 guided in the frame assembly element 3 then takes place automatically through the closing movement of the door 20 and the right-hand guide ramp 4.

When the door 20 is moved alternately into the right-hand open position OR and into the left-hand open position OL, the locking lever 1 is automatically moved into the right-hand locking contours 2.2b, 3.2b, ie the locking contours 2.2b, 3.2b of the right locking contour pair, or in the left locking contours 2.2a, 3.2a, i.e. the locking contours 2.2a, 3.2a of the left locking contour pair, and locked in them independently. A manual intervention is not required apart from the unlocking of the door-side guide element 1.1. How this based on the Figures 2a and 2b can also be seen, the locking lever 1 is in its locking positions FL, FR on Edge of the opening so that the locking lever 1 or passing through the door opening is hardly affected. This means that the locking lever 1 in the locking position FL, FR encloses an angle of just under 180 degrees with the guide 2.1 of the door mounting element 2 and in this respect extends almost parallel to the door surface in this position.
