Description

The invention relates to a lock, in particular a door lock, with a locking bolt that can be rotated back and forth between a locking position and an unlocking position, a lock holder into which the locking bolt can engage in the locking position and a stop that limits the rotational movement of the locking bolt. Such a lock is described in the document US2013099509 disclosed.

Such locks are used in many areas of technology, for example to close flaps, doors, hatches or similar elements. In the following, we will refer to a door as a representative of these elements.

Corresponding locks usually have a locking bolt that can be rotated back and forth between a locking position and an unlocking position, which can be a sash tongue, for example. The locking bolt is usually arranged on the inside of a door and can be rotated back and forth between the locking position and the unlocking position from the outside of the door via an actuating element, such as a handle lever.

In the locked position, the locking bolt ensures that the door cannot be opened, as in this position the locking bolt engages in a locking holder on the frame and the door is thus fixed in relation to the door frame. To open the door, the locking bolt must first be turned to the unlocked position, in which the locking bolt no longer engages in the locking holder and in which the door can be opened in relation to the frame.

Furthermore, a stop is usually provided to limit the rotation of the locking bolt. When the locking bolt is in the unlocking position, it rests against the stop so that no further rotation into the unlocking opening is possible. The reason for this stop is that it is often undesirable for the locking bolt to be able to rotate freely, since, for example, if it were to rotate completely in the unlocking direction, the locking bolt would still engage in the bolt holder. In this respect, the stop can ensure that the locking bolt can only be rotated to the unlocking position and not beyond.

When the locking latch is in the unlocked position, the door can be moved and rotated around a pivot axis that is usually vertical. There are essentially two types of Doors, namely right-hinged doors, where the hinge or pivot axis of the door is on the right-hand side, and left-hinged doors, where the hinge or pivot axis is on the left-hand side. Although this is much less common, it is also possible to hinge doors at the top or bottom.

In order to convert a door from a right-hinged door to a left-hinged door, for example, not only do the frame-side elements, such as the lock holder, have to be dismantled and then reassembled on the other side of the frame, but the door-side elements, such as the locking latch and the operating elements, also have to be replaced accordingly. Such a conversion is therefore quite complex and time-consuming.

However, it is much easier to turn the door around. This is because then only the frame-side elements need to be swapped and the door-side elements are already on the correct side of the door after the rotation. One disadvantage, however, has been found to be that the operating element can then have a different orientation. This is because if, for example, on a left-hinged door, a handle lever points downwards, it points upwards after the door is turned, which requires unusual operation and is therefore undesirable. Since the locks usually have stops that limit the movement of the handle lever or locking latch, it is often not possible to simply turn the handle lever 180 degrees. Although the handle can usually be dismantled and then turned over, dismantling usually involves a considerable amount of work, especially if the screws that need to be loosened are not easily accessible.

Based on this, the invention sets itself the task of providing a closure that can be adjusted more easily.

This task is solved in a closure of the type mentioned above by arranging the stop receptacles on the closure holder.

By designing the stop as an interchangeable stop, the position of the stop can be changed, for example, depending on whether the door is to be hinged on the left or right, so that the lock and thus also the door can be easily converted. For example, a handle lever and thus also the locking bolt can be freely rotated into the desired position after the interchangeable stop has been removed. Once the desired handle lever position has been reached, the stop can be used optionally and depending on requirements in one of the different stop holders.

In this respect, it has proven to be advantageous if the stop is detachably connected to the respective stop holders. This enables the stop to be arranged easily and quickly on the respective stop holder.

With regard to the positioning of the stop, it has proven to be advantageous if the stop can be moved from one stop holder to another. This repositionability means that the stop can be removed from one of the stop holders very easily and without the use of additional tools, in particular pulled out, and then inserted into the other stop holder. This enables a very simple and intuitive repositioning of the stop and conversion of the lock. Furthermore, it is also possible to that the stop can be screwed or snapped into the respective stop holders.

It has also proven to be advantageous if the stop is used in one stop position to limit the movement of the locking bolt on a left-hinged door and in one stop position to limit the movement of the locking bolt on a right-hinged door. The stop receptacles or the stop positions assigned to the stop receptacles can therefore be coordinated with the door stop so that the stop can be moved from one stop receptacle to another stop receptacle in order to convert the door. It has also proven to be advantageous if two stop receptacles are provided into which the same stop can be optionally inserted.

With regard to the design of the locking bolt, it has proven to be advantageous if it is designed as a double locking bolt with two locking elements. The design as a double locking bolt offers the advantage that a locking bolt has two different locking and unlocking positions. This has also proven to be advantageous in terms of convertibility. The two locking elements can be opposite each other or offset by 180°, so that the locking bolt can have a propeller-shaped shape. In the unlocking position, one locking element can engage in the lock holder to lock the door, and when moving into the unlocking position, the other locking element can then strike a stop that prevents the locking bolt from moving beyond the unlocking position. In this respect, it is advantageous if the locking bolt and thus also the handle lever do not move more than 180° when moving between the locking position and the unlocking position. degrees. Alternatively, it is also possible for the locking bolt to have only one locking element.

With regard to the design of the locking bolt as a double locking bolt, it has proven advantageous if one of the two locking elements can engage in the locking holder to lock the door and the other locking element can strike the stop to limit the rotational movement. Which of the two locking elements engages in the locking holder and which strikes the stop can depend on the stop of the door. For example, with a left-hinged door, the locking element that engages in the locking holder to lock the door can be the locking element that strikes the stop in the unlocked position with a right-hinged door and prevents further movement of the locking bolt in the unlocking direction.

With regard to the locking bolt, it has also proven to be advantageous if it is rotatably mounted in a bolt housing. This enables the locking bolt to rotate easily. The locking bolt can be moved back and forth between the locking position and the unlocking position, for example, using a handle lever, whereby the handle lever can be arranged on the outside of the bolt housing and the locking bolt can be arranged on the inside of the bolt housing. An actuating shaft can extend through the bolt housing, connecting the handle lever to the locking bolt. A gear can also be provided so that the handle lever is not connected directly to the locking bolt, but via the gear. The bolt housing can act as a cover and cover the locking bolt in such a way that it is not visible from the outside. This can prevent manipulation and also protect the internal mechanism from dirt and external influences. Furthermore, the bolt housing can be arranged on the door side, in particular The latch housing can be located on an outside side of the door.

With regard to the stop receptacles, it has proven to be advantageous if these are arranged on the bolt housing. This embodiment is not part of the invention, but is only mentioned here as background. This arrangement makes it very easy to arrange the stop in different positions on the bolt housing. The other components of the lock do not then have to be changed when converting.

In this context, but not according to the invention, it has proven advantageous if the stop receptacles are designed as insertion openings into which the stop can be optionally inserted. The stop can be very easily inserted from the outside through the insertion openings and it is not necessary to dismantle the latch housing. The corresponding insertion openings can extend from the visible front of the latch housing, on which the handle is also arranged, into the interior of the latch housing so that they are easily accessible. Furthermore, however, it is also possible for the insertion openings to be closable with a cap so that, for example, no contaminants can penetrate into the interior of the latch housing via the insertion openings. Furthermore, the stop can also be screwed, clipped or latched into the insertion openings. The insertion openings can extend through the front of the latch housing to or into the opposite side of the latch housing.

With regard to the design of the stop, it has proven to be advantageous if it is designed as a stop pin or a stop screw. Stop pins can therefore be easily inserted into either of the two insertion openings and then limit the rotation of the locking bolt accordingly. Stop screws can be screwed into the stop receptacles. which may require the use of a screwdriver, but at the same time this design allows the stop to be held particularly securely in the bolt housing.

According to the invention, it has been found to be advantageous if the stop receptacles are arranged on the lock holder. This design means that the bolt housing does not have to have any insertion openings and the various stop receptacles are therefore not visible from the outside. In addition, the stops arranged on the lock holder can only be changed when the door is open. This can lead to better protection against manipulation, since the stops are not visible and cannot be reached when the door is closed. Nevertheless, even if the stop receptacles are arranged on the lock holder, the stops can be changed very easily, especially by hand.

With regard to the design of the stop, it has proven to be advantageous if it has a locking stop surface for limiting a rotary movement in the locking direction and an unlocking stop surface for limiting the rotary movement in the unlocking direction. This means that only a single stop is required both to limit a movement in the locking direction and to limit a movement in the unlocking direction. The stop can have two locking surfaces that are opposite each other and of which only one surface is used depending on the stop position. This can be the unlocking stop surface that faces the locking bolt in the locking position. The surface opposite this unlocking stop surface can rest against the contact surface of the stop holder. The unlocking stop surface and the locking stop surface can be arranged perpendicular to each other. The stop can be cube-shaped or cuboid-shaped. and the two locking stop surfaces can be arranged on opposite sides of the cube or cuboid.

With regard to the design of the lock holder, it has proven to be advantageous if it has a mounting element by means of which the lock holder can be fastened to a door frame in a mounting plane, a holding element and a holding surface arranged at a distance from the mounting plane, which can be gripped behind by a door-side locking bolt to lock the door. A corresponding lock holder design has proven successful in the past.

With regard to the holding surface, it has proven to be advantageous if the holding surface and the mounting plane are arranged parallel to one another. This allows the locking bolt to rest as completely as possible on the holding plane in the locking position, which ensures good force transmission and thus a secure hold of the locking bolt. The holding surface can also be arranged parallel to the surface of the door frame. It is not absolutely necessary for the holding surface to be a flat surface; the holding surface can also be curved in sections, for example.

In a further development of the invention, it is further proposed that the holding element is connected to the mounting element via two supports. The holding element can be arranged parallel to the mounting element via these two supports, so that the holding element together with the two supports essentially has a C-shaped contour. The two supports can be arranged perpendicular to the mounting plane and perpendicular to the holding surface, so that the holding surface also runs parallel to the mounting plane. The two supports can be connected to the holding element at the respective edge areas, so that there is a space between the There is enough space between both supports and the locking bolt on the door side can grip behind the holding element or the holding surface during a turning movement.

Furthermore, it has proven to be advantageous if the holding element is connected in one piece with the supports and with the assembly element. The holding element, the supports and the assembly element can thus be manufactured in one work step and designed, for example, as an injection-molded part. This enables simple and cost-effective series production.

In order to ensure that the stop can be held reliably on the stop holders, it has proven advantageous if the stop holders can hold the stop in a form-fitting manner, so that the stop can then no longer move relative to the stop holder in at least one direction, in particular in two directions. The stop holders can, however, be designed in such a way that the stop can be removed from the stop holders in the opposite direction to the installation direction. Furthermore, the stop holder can have a counter stop against which the stop can rest when it is in the stop holder.

In this regard, it has also proven to be advantageous if the stop receptacle comprises a recess extending into the holding element and/or into the mounting element. The recess can serve to guide the stop so that it can be pushed into the stop receptacle in the mounting direction. Accordingly, the recesses can also extend into the holding element and/or into the mounting element in the mounting direction. The mounting direction can extend parallel to the mounting plane and the holding surface. The recess can be designed as an elongated hole so that the stop can be received in the recess in a form-fitting manner.

Furthermore, it has proven to be advantageous with regard to the stop holder if it comprises two recesses extending parallel into the holding element and/or into the mounting element. The holding element can be arranged parallel to the mounting element so that the recesses can ensure reliable mounting of the stop. This design has proven to be effective in terms of reliable mounting of the stop.

According to a further preferred embodiment, it has proven advantageous if the stop has guide elements, in particular guide pins, by means of which it is guided in the recesses. Due to the interaction of the guide elements and the recesses, the position of the stop in the stop receptacle can be firmly defined and even if the locking bolt or the locking elements of the locking bolt strike the stop, the locking bolt cannot move them. The number of recesses can correspond to the number of guide elements.

Furthermore, it has been found to be advantageous with regard to the stop holder if it has a contact surface for the stop to be placed on. The contact surface can also ensure that the stop is reliably held in the corresponding stop position. The stop surface can be part of a support via which the holding element is connected to the mounting element. The contact surface can be used to absorb forces acting on the stop, in particular if the stop only has one insertion element.

To connect the stop with the stop holder, it has proven to be advantageous if the stop can be connected to the lock holder via a holding shoe that can be attached to the holding element. The holding shoe can be locked into the retaining element of the lock holder, so that in order to release or change the position of the stop, the retaining shoe must first be removed from the retaining element. No additional tools are required to remove the retaining shoe or the stop from the corresponding stop holder.

From a design point of view, it has proven to be advantageous if the holding shoe has two legs of different thicknesses. The two legs can extend parallel to one another and, when the holding shoe is connected to the holding element, one leg can be arranged on the side of the holding element facing away from the mounting plane and one leg can be arranged on the side of the holding element facing the mounting plane.

Furthermore, the surfaces of the legs can be designed as sliding surfaces so that the locking bolt can slide on these surfaces when locked or unlocked. When locked and unlocked, the locking bolt always slides on the surface of the leg that faces the mounting plane in the corresponding mounting position. It has also proven to be advantageous if the holding shoe has a U-shaped cross-section. A corresponding cross-section allows the holding shoe to be pushed onto the holding element from one direction and to grip around the holding element in a form-fitting manner.

With regard to the design of the holding shoe, it has proven to be advantageous if it has at least one spring arm, via which the holding shoe can lock with the holding element and/or the support(s). The holding shoe can thus be detachably connected to the holding element via the spring arm and held securely to it. In order to ensure even force distribution, at least two spring arms have proven to be advantageous in practice. The spring arm(s) can each have one or more locking lugs, which ensure that the spring arm(s) deform automatically when the holding shoe is placed on the holding element and then automatically grip behind the holding element or the supports when the end position is reached. The spring arms and the locking lugs are advantageously designed in such a way that the holding shoe can then be removed from the holding element again without the additional use of tools. The spring arms can be arranged on the side of the holding shoe and grip the holding element and/or the supports like a clamp in the assembly positions.

In a further development of the invention, it has been found to be advantageous if the holding shoe has four spring arms. One spring arm can be arranged on each side of the leg. The four spring arms can have locking lugs that all point in one direction. In the assembly position, the locking lugs of two spring arms can engage behind the holding element, in particular the locking lugs of the spring arms that are arranged on the side of the narrower leg.

So that the holding shoe can be reliably connected to the holding element, the holding element can have a guide for the holding shoe. The guide can prevent the holding shoe from snagging or tilting when pushed onto the holding element, which further simplifies the assembly and disassembly of the holding shoe. The guide can comprise two guide webs that serve to guide the holding shoe linearly. The holding shoe can be arranged between these two webs in the connected position. The guide has proven to be particularly advantageous when the holding shoe has four spring arms. and/or if the holding shoe is shorter than the holding element.

It is also possible for the holding shoe to extend over the entire length of the holding element. In this case, an additional guide on the holding element is not necessarily required, but the spring arms, which can grip the holding element and/or the supports at the sides, can serve to guide the guide shoe in relation to the holding element.

With regard to the design of the holding shoe, it has also proven to be advantageous if the holding shoe holds a guide element of the stop in the stop receptacle. The holding shoe can thus ensure that the stop is held securely in the stop receptacle. The corresponding guide element of the stop can extend through the recess of the stop receptacle and can then be held or secured in this receptacle by the holding shoe. The holding shoe thus ensures that the stop is positively received in the stop receptacle. The holding shoe can preferably encompass a guide element of the stop at least in sections. To encompass the guide element of the stop, the holding shoe can have one or more receptacles which, in the connected position, are aligned with the recesses of the stop receptacles in such a way that the holding shoe can be received in a positively locking manner. The recesses can be designed as elongated holes and extend between the legs and the spring arms of the holding shoe.

With regard to the connections of the stop with the stop holder, it has also proven to be advantageous if the stop has a recess so that a spring arm of the holding shoe can be moved through this This design allows the guide element of the stop to be gripped by the holding shoe on both sides of the holding element and the stop is thus held securely in the stop holder.

With regard to the object mentioned at the outset, a door with a lock is also proposed, which is designed in the manner described above. This results in the advantages already described with regard to the lock.

In order to fix a door 11 relative to a door frame 12 so that the door 11 cannot be opened, a lock 14 with a frame-side lock holder 10 and a door-side locking latch 7 is provided, see. Fig.7 . The locking bolt 7 is rotatably mounted in a bolt housing 15 and can be rotated back and forth between a locking position V and an unlocking position E. In the locking position V, the locking bolt 7 engages in the lock holder 10, so that the door 11 is then fixed against the frame 12 and can no longer be opened. In order to open the door 11, the locking bolt 7 must first be rotated back into an unlocking position E, in which the locking bolt 7 no longer engages in the lock holder 10. The rotation of the locking bolt 7 from the locking position V to the unlocking position E is explained below using the Fig. 14a to d will be explained in more detail.

First, the design of the closure holder 10 will be described based on the illustration in the Fig.1 can be described. The lock holder 10 has a mounting element 1 which is designed in the manner of a base plate and via which the lock holder 10 can be connected to the frame 12 of a door 11. The elongated mounting element 1 has a hole in the form of an elongated hole on each side, via which the mounting element 1 can be screwed to the door frame 12. Due to the design as an elongated hole, the mounting element 1 can still be moved within certain limits, even if it is already connected to the frame 12 via screws, as long as the screws are not yet firmly tightened. After the alignment of the mounting element 1, the screws are then tightened so that extensive movement of the mounting element 1 relative to the frame 12 is no longer possible. The lock holder 10 can thus be mounted via the mounting element 1 in a mounting plane M to the door frame 12. The mounting plane M then also corresponds to the plane of the surface of the door frame 12 on which the lock holder 10 is attached.

Furthermore, the closure holder 10 has a holding element 2, which is connected to it via two supports 1.1. Since the two supports 1.1 have the same height and are arranged perpendicularly on the mounting element 1, the holding element 2 extends essentially parallel to the mounting element 1 or to the mounting plane M.

To lock the door 11, the locking bolt 7 is now rotated into the space between the mounting plane M or the mounting element and the holding element 2, so that the locking bolt 7 can no longer be moved in a perpendicular direction to the mounting plane M and the door 11 is fixed relative to the frame 12. The position of the holding element 2 or the distance of the holding element 2 relative to the mounting plane M thus defines the closed position of the door 11.

A door seal is arranged between the door 11 and the frame 12, although this is not shown in the figures. This door seal is compressed when the door 11 is in the closed position, so that the door 11 does not rattle and cannot be moved in the closed position. In addition, the seal can also ensure that gas exchange between the interior and the exterior is prevented or at least reduced. Due to the compression of the seal, it exerts at least a certain force on the door 11 in the direction of the open position and thus presses the locking bolt 7 from the direction of the mounting element 1 onto the holding element 2. The side of the holding element 2 facing the mounting plane M then functions as a holding surface 3 against which the locking bolt 7 rests in the locked position.

In order to compensate for manufacturing tolerances or, if necessary, signs of aging of the seals, a retaining shoe 5 is also provided. The function and design of the retaining shoe 5 is described below in particular with regard to the Fig. 1 to 6 will be described in more detail. But first, we will now look at the Fig. 7 to 14d First, it will be described how a door 11 is to be converted, for example from a left-hand stop to a right-hand stop.

A left-hinged door 11 is shown in the left illustration of the Fig.7 The door 11 has a lock 14 which fixes the door 11 in the locking position V relative to the frame 12, so that the door 11 can then no longer be opened. The corresponding lock 14 has a rotatable locking bolt 7 and a lock holder 10, as already described above. The middle and right illustration of the Fig.7 now illustrate how the left-hinged door 11 can be converted so that it is then hinged to the right.

First, the door 11 is completely detached from the frame 12 and then rotated by 180 degrees. The frame-side elements of the lock 14 must be detached from the right side of the frame 12 and then remounted on the left side of the frame 12. The same can also apply to the door hinges. If the door 11 is then rotated by 180 degrees and reattached to the frame 12, it can be opened, closed and locked again using the lock 14. As can be seen from a comparison of the right and middle representation of the Fig.7 However, it is noticeable that when the door 11 is turned over, the orientation of the handle lever 13 also changes. This is because it no longer points downwards, but upwards, which is usually not desired. The following describes how the lock 14 can be converted without having to dismantle it or the handle lever 11.

A first embodiment, not according to the invention, will first be described on the basis of the Fig. 8a, b and 9a, b are described. In the Fig. 8a, b the bolt housing 15 is shown with the handle lever 13 arranged thereon, which is rotatably coupled to the locking bolt 7 on the inside of the bolt housing 15. The bolt housing 15 has two stop receptacles 8, 9 designed as insertion openings, into which the stop 6 designed as a stop pin can be optionally inserted. The interior of the bolt housing 15 is the Fig. 9a and 9b By positioning the stop 6 in the various stop receptacles 8, 9, a movement of the locking bolt 7 can be limited in different rotation ranges.

In the Fig. 9a the locking bolt 7 is shown in a locking position V. The locking holder 10 is not shown. The locking bolt 7 is designed as a double locking bolt and has two opposing locking elements 7.1 and 7.2. In the position according to Fig. 9a the locking element 7.2 initially rests against the stop 6 in the stop holder 9, so that the locking bolt 7 can only be turned clockwise, but not anti-clockwise, since the stop 6 prevents this rotation. If the locking bolt 7 is now turned clockwise, the locking element 7.2 is swung out of the lock holder 10 (not shown) and the door 11 can be opened. The locking bolt 7 can be turned until the locking element 7.1 rests against the other side of the stop 6. The stop 6 thus prevents the handle lever 13 and thus also the locking bolt 7 from being turned far enough for the locking element 7.1 to engage in the lock holder 10.

In the presentation of the Fig. 9b the stop 6 is inserted into the other stop receptacle 8. The locking bolt 7 can now only be turned counterclockwise from this position and only until the locking element 7.1 hits the right side of the stop 6. Although in the illustrations of the Fig. 9a and 9b the locking bolt 7 is designed as a double locking bolt, the device also functions to the same extent with locking bolts 7 that have only one locking element 7.1. The only difference then is that the handle lever 13 can be pivoted by approximately 180 degrees further than in the design with a double locking bolt.

In order to convert the door 11 from a left-hand door stop to a right-hand door stop, for example, the stop 6 must first be pulled out of the respective stop holder 8, 9. The handle lever 13 and the locking latch 7 can then be freely rotated so that the handle lever 13 can be turned into the desired downward-facing position, as shown in the right-hand illustration of the Fig.7 can be seen. In a next step, the stop 6 can then be inserted into the appropriate stop holder 8 or 9 and the holes arranged in the outside of the latch housing 15 can be closed, for example with caps.

As an alternative to the arrangement of the stop receptacles 8, 9 or the stop 6 on the bolt housing 15, the stop receptacles 8, 9 can also be arranged on the lock holder 10. With this embodiment according to the invention, the outside of the bolt housing 15 no longer has to have any insertion openings for the stop 6. This embodiment will be explained below based on the illustration in the Fig. 11 and 12 As is particularly evident in the Fig. 11 As can be seen, the closure holder 10 has two stop receptacles 8, 9, which are arranged on different sides of the closure holder 10 and which are essentially located between the Mounting element 1 and the holding element 2. Both the holding element 2 and the mounting element 1 have two recesses 8.1, 9.1 for each of the two stop receptacles 8, 9, which extend like elongated holes into the mounting element 1 and into the holding element 2 in the mounting direction MR. In this embodiment, the stop 6 has a total of four guide elements 6.3 designed like pins or bolts, which are guided in the recesses 8.1, 9.1 when the stop 6 is inserted into the respective stop receptacle 8, 9. The stop 6 can therefore be inserted either into the stop receptacle 8 or into the stop receptacle 9 in the mounting direction MR and can also be removed from the stop receptacles 8, 9 accordingly.

The holding shoe 5 is used to attach the stop 6 to the closure holder 10, which therefore has a dual function. The holding shoe 5 is not only used to adjust the distance A1, A2 of the holding surface 3 from the mounting plane M, but it also serves to secure the stop 6 in the corresponding stop holder 8, 9 of the closure holder 10. As described in more detail below, the holding shoe 5 can be locked to the holding element 2 and/or to the supports 1.1. In this locking position, the holders 5.4 arranged between the spring arms 5.3 and the legs 5.1, 5.2 grip the two upper guide elements 6.3 of the stop 6 and thus hold them in the recesses 8.1, 9.1 of the respective stop holder 8, 9. The stop 6 is then received in a form-fitting manner between the holding shoe 5 and the mounting element 1 as well as the holding element 2. Furthermore, the stop receptacles 8, 9 also have a contact surface 8.2, 9.2, which are each part of one of the supports 1.1. These contact surfaces 8.2, 9.2 serve as additional support and thus ensure that the forces acting on the guide elements 6.3 are reduced, especially when the locking bolt 7 strikes the stop 6. In the sectional view of the Fig. 12 is still It is clearly shown how the guide elements 6.3 are accommodated in the mounting holder 1, the holding element 2 and the holding shoe 5. The holding shoe 5 which surrounds the holding element 2 presses the guide element 6.3 both above and below the holding element 2 into the corresponding recess 8.1, 9.1 of the respective stop holder 8, 9 and then, when it is locked with the holding element 2 or with the supports 1.1, ensures that the stop 5 is held securely in the corresponding stop holder 8, 9.

Furthermore, especially in the Fig. 11 It can be seen that the stop 6 has two recesses 6.4 at the upper end. When the stop 6 is held by the holding shoe 5 in the stop holder 8, 9, the lower spring element 5.3 located on the side of the stop holder 8, 9 used lies in the recess 6.4 pointing towards the middle of the lock holder 10. The recess 6.4 thus ensures that the corresponding guide element 6.3 can also be gripped by the lower holder 5.4 below the holding element 2. This is also shown in the illustration of the Fig.2 in which the stop 6 is arranged in the right stop holder 9. If the stop 6 is arranged in the left stop holder 8, the holding shoe 5 engages around the corresponding other guide element 6.3 of the stop 6.

The following is based on the representations of the Fig. 10a to 10d a further embodiment of the stop 6 and the stop receptacles 8, 9 is described. In this embodiment, the holding shoe 5 is longer than the one in the Fig.2 and 11 shown holding shoe 5 and in addition, the holding shoe 5 in this embodiment has only two spring arms 5.3 and not four spring arms 5.3. Furthermore, the stop 5 differs from the stop 5 described above in that it only has two guide elements 6.3 and the stop receptacles 8, 9 accordingly also only have two recesses 8.1, 9.1, one in each case in the mounting element 1 and in the holding element 2. The mounting element 1 and the holding element 2 are therefore more stable in this embodiment.

The holding shoe 5 also has a receptacle 5.4 arranged between the spring arms 5.3 and the legs 5.1, 5.2. In this design, however, the receptacle 5.4 is not used to hold the guide elements 6.3 in the respective recess 8.1, 9.1, but also to grip the supports 1.1 laterally in the manner of a clamp, as has already been described with regard to the holding element 5. In contrast to the design with the four recesses 8.1, 9.1 per stop receptacle 8, 9, the contact surface 8.2, 9.2 is of greater importance in this design. This is because the contact surface 8.2, 9.2 ensures that the stop 6 does not twist when the locking bolt 7 strikes it. A corresponding sectional view through the stop 6 and the lock holder 10 is shown in the Fig. 13 shown.

As this continues in the Fig. 10a to 10d As can be seen, the stop 6 can be switched back and forth between the two stop holders 8, 9. In the illustration of the Fig. 10a the stop 6 is initially in the first stop position P1 in the stop holder 8. After the holding shoe 5 has been removed from the holding element 2, the stop 6 can be removed by hand from the stop holder 8, turned by 180 degrees and then inserted into the stop holder 9. Finally, the holding shoe 5 is then put back on the holding element 2 in order to secure the stop 6 in the stop holder 9. This position is in the Fig. 10d shown.

Based on Fig. 14a to 14d The unlocking of the lock 14 will now be explained in more detail. In the position shown in the Fig. 14a As shown, the closure 14 or the locking latch 7 is in the locking position V. The stop 5 is arranged on the closure holder 10 and is inserted into the stop holder 9 in the stop position P1. In the locking position V, the locking element 7.1 of the locking bolt 7 rests against a locking stop surface 6.1. This stop surface 6.1 is also in the Fig. 11 This is the stop surface 6.1 against which the locking bolt 7 rests in the locking position V. This locking stop surface 6.1 is arranged either to the left or right of the stop 6 depending on the stop position P1, P2 and always points towards the center of the bolt holder 10.

To unlock, the locking latch 7 must now be turned clockwise, as shown in the Fig. 14a indicated by an arrow. During this rotational movement it passes through the Fig. 14 b and c As soon as the locking element 7.1 is then swung out of the lock holder 10 and the locking element 7.1 no longer engages behind the holding surface 3 of the lock holder 10, the door 11 can be opened. This unlocking position E is in the Fig. 14d It can be seen that in this position the locking element 7.2 strikes the stop 6 or the unlocking stop surface 6.2 and thus a further rotation of the locking bolt 7 in the unlocking direction is no longer possible. The unlocking stop surface 6.2 is also shown in the illustration of the Fig. 11 to recognize.

If the stop 6 is now pulled out of the stop holder 9 and inserted into the stop holder 8, a different stop pattern results. Starting from the position in the Fig. 14d the locking bolt 7 can then be rotated further clockwise until the bolt end 7.2 then strikes the stop 6 located in the stop position P1. The locking element 7.2 then rests in this locking position V on the locking stop surface 6.1 of the stop. The locking stop surface 6.1 is not, however, the same surface on which the locking element 7.1 strikes when the stop 6 is in the stop position P1, as described above, but the locking stop surface 6.1 is opposite this surface, as can be seen, for example, from the Fig. 11 is visible. If the locking bolt 7 is then rotated anti-clockwise from this position into the unlocking position E, the locking element 7.1 strikes the unlocking stop surface 6.2 of the stop 6 and thus limits further rotation of the locking bolt 7.

By switching the stop 6 between the two stop receptacles 8, 9, the rotary movement of the locking bolt 7 can be controlled. Since, depending on the stop position, the locking element 7.2 and the locking element 7.1 engage behind the holding surface 3 of the locking holder 10 and the locking holder 10 is connected to the handle lever 13, the position of the handle lever 13 in the locking position V and the unlocking position E can also be adjusted.

The retaining shoe 5 has a dual function and serves both to secure the stop 6 in the stop holders 8,9, but at the same time the distance of the retaining surface 3 from the mounting plane M can be adjusted via the retaining shoe 5. In the following, with regard to the Fig. 1 to 6 the function and design of the holding shoe 5 with regard to the distance adjustment are explained in more detail.

A door seal is arranged between the door 11 and the frame 12, but is not shown in the figures. This door seal is compressed in the closed position of the door 11, so that the door 11 does not rattle and cannot be moved in the closed position. In addition, the seal can also ensure that gas exchange between the interior and the exterior is prevented or at least reduced. Due to the compression of the seal, it exerts at least a certain force on the door 11 in the direction of the open position and presses the locking bolt 7 thus from the direction of the mounting element 1 onto the holding element 2. The side of the holding element 2 facing the mounting plane M then functions as a holding surface 3 against which the locking bolt 7 rests in the locked position.

In order to compensate for manufacturing tolerances or, if necessary, signs of aging of the seals, a retaining shoe 5 is also provided. The function and design of the retaining shoe 5 will now be described below, in particular with reference to the Fig. 1 to 6 described in more detail.

The retaining shoe 5 is detachably connected to the retaining element 2 and can be pushed onto the retaining element 2 from the front in an assembly direction MR aligned parallel to the assembly plane M. The retaining shoe 5 reduces the gap between the retaining element 2 and the assembly element 1, which accordingly also leads to a displacement of the retaining surface 3 in the direction of the assembly plane M. The retaining shoe 5 thus means that the locking bolt 1 is closer to the assembly plane M in the locking position V and thus also closer to the door frame 12. Accordingly, the door 11 is then pressed more firmly onto the seal in the closed position. As can also be seen, it is not necessary to connect the retaining shoe 5 to the retaining element 2 using a tool, but the retaining shoe can simply be pushed onto the retaining element 2 by hand and it then automatically locks into place with the retaining element 2 and/or with the supports 1.1, which is described in more detail below.

The holding shoe 5 can be connected to the holding element 2 in two different mounting positions M1, M2. The mounting position M1 is shown in the sectional view of the Fig. 3 and the mounting position M2 in the sectional view of the Fig.4 It can also be seen that the holding shoe 5 comprises two legs 5.1 and 5.2, which have a different thickness.

The leg 5.1 is significantly thinner than the leg 5.2 and the latter is only about half the thickness of the leg 5.2. Both in the representation of the Fig. 3 as well as the Fig.4 It is the same holding shoe 5 in different mounting positions M1, M2. The holding shoe 5 is therefore attached to the holding element 2 in such a way that the thicker leg 5.2 faces the mounting plane M and in the other way round, so that the thinner leg 5.2 faces the mounting plane M. The holding shoe 5 was therefore rotated by 180 degrees.

It can also be seen that the different leg thicknesses also mean that the distance A1, A2 of the holding surface 3 to the mounting plane M is different in each mounting position M1, M2. The holding surface 3 designates the surface of the leg 5.1, 5.2 against which the locking bolt 7 rests in the locked position, i.e. the surface of the holding shoe 5 that faces the mounting plane M. Because the thicker leg 5.2 faces the mounting plane M in the mounting position M1, the distance A1 of the holding surface 3 to the mounting plane M is correspondingly smaller than in the second mounting position M2. This is also clear when comparing the two distances A1 and A2 in the different mounting positions M1 and M2, which are shown in the Fig. 3 and 4 are shown. The holding shoe 5 thus makes it possible to adjust the distance between the holding surface 3 and the mounting plane M in three different stages. If no holding shoe 5 is used, the distance is greatest and the locking bolt 7 engages behind the holding element 2 in the locking position V and then rests against it. If the holding shoe 5 is used in the first mounting position M1, the distance is reduced to the distance A1, and if the holding shoe 5 is used in the second mounting position M2, the distance is reduced even further to the distance A2.

In the Fig. 5 and 6 Two differently designed holding shoes 5 are now shown. The holding shoe 5 according to Fig.5 corresponds to the one in the Fig. 1 and 2 The two legs 5.1, 5.2 are parallel to each other and enclose the holding element 2 in the attached position. In order for the holding element 5 to be attached to the holding element 2 as reliably as possible, the holding element 2 has a guide 2.1 which consists of two parallel webs, as shown in the illustration of the Fig.1 can be seen. In the attached position, the holding shoe 5 is then located between these two webs, which in this respect serve as a linear guide.

In order to ensure that the holding shoe 5 is held reliably on the holding element 2 even when the locking latch 7 is moved into the unlocking position E and thereby slides onto the holding shoe 5, the holding shoe 5 has four spring arms 5.3, one of which is located on each side of the two legs 5.1, 5.2. In order for the spring arms 5.3 to lock into the holding element 2, each spring arm 5 has a locking lug, of which two then grip behind the holding element 2 depending on the mounting position M1, M2 of the holding shoe 5, as shown in the illustration of the Fig. 3 and 4 can be seen. The locking lugs of all four spring arms 5.3 point in the same direction. Furthermore, the holding shoe 5 has receptacles 5.4 extending between the spring arms 5.3 and the legs 5.1, 5.2, which in the illustration of the Fig.1 can be clearly seen. The function of these mounts 5.4 has already been discussed in more detail above with regard to stop 6.

In the Fig.6 the holding shoe 5 is shown in a second embodiment. The legs 5.1, 5.2 of this embodiment also extend parallel to each other and encompass the holding element 2 from above and below. In contrast to the holding shoe 5 according to Fig.5 However, in this embodiment, the holding shoe 5 has only two spring arms 5.3, which extend over the entire height of the holding shoe 5. This holding shoe 5 is also longer so that it can encompass the entire holding element 2 with the spring arms 5.2, as shown in the illustrations of the Fig. 10a and 10b can be seen. Since this holding shoe 5 is guided over the spring arms 5.3 that are laterally attached to the holding element 5 or to the supports 1.1 when plugged in, an additional guide 2.1 on the holding element 2 is not absolutely necessary in this design.

Furthermore, in the Fig. 10a and 10b It can be seen that the two spring arms 5.3 each have a locking lug that faces each other. These locking lugs engage around the holding element 2 or the supports 1.1 and then ensure, quite analogously to the design according to the Fig.5 described spring arms 5.3 ensure that the holding shoe 5 is held securely on the holding element 2. Furthermore, in this embodiment, the holding element 2 has notches in the upper end area into which the locking lugs of the spring arms 5.3 can engage. The corresponding notches are, for example, in the Fig. 10b to recognize.

With regard to the choice of material for the holding shoe 5, materials that have good sliding properties have proven particularly advantageous in practice. There are two main reasons for this. The locking latches 7 must be very strong and are therefore usually made of metal and, to prevent corrosion, mostly of galvanized metal. Since the locking latch 7 slides on the holding surface 3 when it grips behind it, the galvanized surface of the locking latches 7 may be rubbed off, which is then associated with an increased risk of corrosion. If the holding shoe 5 and in particular the corresponding surfaces of the holding shoe 5 on which the locking latch 7 slides have good sliding properties, the risk of material being removed is reduced.

In addition, if the locking bolt 7 exerts too much pressure on the holding surface 3, the holding shoe 5 may take the holding shoe 5 with it into the unlocking position E when the locking bolt 7 is rotated, thereby pulling it away from the holding element 2. In this respect, good sliding properties also enable the holding shoe 5 to be held securely on the holding element 2. Possible materials for the holding shoe 5 are, for example, plastic, in particular POM, brass or bronze. Furthermore, surface coatings can also be used to improve the sliding properties.
