Description

The invention relates to a closure, in particular a door closure, according to the preamble of patent claim 1. The invention also relates to a door with a closure.

Such closures can be used in very different areas and both in swing and sliding doors, but also in flaps, hatches or windows. Primarily, however, such closures are used in pivoting doors which, in order to open or close, have to be pivoted about a pivot axis which is usually arranged vertically. The locks are usually located near the edge of the door that is opposite the pivot axis of the door.

For locking a door, such closures usually have a locking element which can be rotated back and forth about a locking axis of rotation between a locking position and an unlocking position. The door is released in the unlocked position and can be moved as desired, i.e. opened or closed. When the door is in the closed position and the locking member is in the locked position, the locking member blocks movement of the door so that it cannot be opened. To open the door, the locking element must first be rotated back from the locked position into the unlocked position.

In order to actuate or move the locking element, it can be rotated via an actuating element. The locking element can thus be rotated back and forth between the locking position and the unlocking position via the actuating element.

Furthermore, corresponding closures usually have a closure housing on which the locking element is rotatably mounted and via which the actuating element and the locking element are connected to a door.

In order to limit the movement of the locking element, the lock housing usually has a stop with one or more stop elements, which are usually arranged in such a way that the locking element strikes a stop surface of the stop element or stop elements in the unlocked position and in the locked position. In the case of manual actuation, the person who moves the locking element also receives feedback as to when the locking position and when the unlocking position has been reached.

However, it has turned out to be disadvantageous with such closures that the closure housing is always only suitable for a specific installation situation. For example, due to the fixed position of the stopper in a rectangular swing door, lock housings cannot be used either with a door hinged on the right or with a door hinged on the left. Because with a door hinged on the right, it is necessary to arrange the lock in the area of the opposite left door edge and with a door hinged on the left, the lock must be arranged accordingly on the right door edge. The closures must therefore always be adapted to a specific installation situation.

For example, if you wanted to use the same lock on both a right-hand and a left-hand door, the lock housing would have to be rotated 90 degrees, which leads to problems especially if the lock housing is rectangular or printed and labeled. For this reason, it is generally not possible in practice to turn the breech housing, but it is necessary to provide different breech blocks with different breech housings for different installation situations, the stops of which must be adapted to the corresponding installation situations.

The WO 91/05126 relates to a closure housing with a flange, middle part and rear end for mounting in an opening in a thin wall, such as a sheet metal cabinet door or sheet metal housing cover, the housing being attached to the opening edge or rear surface by means of a after the rear end and the middle part have been pushed through the opening up to the flange the spring or springs engaging the thin wall and the spring(s) engaging the aperture edge or rear surface of the thin wall is held by the outer surface of the center portion of the housing near the housing end or emanates from the housing end of the closure and is axially rigidly connected to the housing.

The DE 201 02 793 U1 discloses a cylinder cam lock with a rotatable locking member, wherein the stop of the locking member is adjustable.

Proceeding from this, the object of the invention is to specify a closure which is also suitable for different installation situations.

With a closure of the type mentioned at the outset, this object is achieved by the features of patent claim 1 .

By arranging the stop on a stop carrier which is detachably connected to the breech housing, the stop can be detached from the breech housing in a simple manner. Due to this two-part configuration, it is possible to use the stop or the stop carrier in a variable manner and to arrange the stop carrier on the breech housing, which is necessary due to the required stop pattern for the respective installation situation. It is not necessary to adapt the lock housing to the installation situation, in particular it is not necessary to turn the lock housing by 90 degrees if it is designed for a left-hand door but is to be used with a right-hand door. Since only the stop supports have to be adapted to the installation situation, the closures can be easily and inexpensively adapted to different installation situations. Furthermore, however, stop carriers can also be connected to the lock housing, which can be used for doors hinged at the top or bottom. A lock housing can therefore form an installation set with different stop supports for different installation situations.

In a development of the invention, it has proven to be advantageous if the stop is designed as a double stop with two stop elements. By designing the stop as a double stop with two stop elements, movement of the actuating element and the locking element between the unlocking position and the locking position can be reliably ensured since the forces acting are divided between the two stop elements. Each of the stop elements can have two stop surfaces. The stop surfaces of a stop element can advantageously be opposite one another. Each stop element can be designed in the manner of a circular ring segment. The two stop elements can be arranged on opposite sides of the stop support.

In a further development of the invention, it is proposed that the stop support can be releasably connected to the breech housing in various assembly positions. Connecting the stop support to the breech housing in different assembly positions results in a different stop pattern for each assembly position. Accordingly, different stop images can also be achieved on a breech housing with only one stop support by arranging the stop support in different mounting positions. The same closure can therefore be used variably for different installation situations. For example, in one assembly position of the stop support, the lock can be used for a door hinged on the left and in another assembly position for a door hinged on the right. Furthermore, it is also conceivable to provide assembly positions for a door hinged at the top or bottom. The various assembly positions can be achieved by rotating the stop support relative to the breech housing.

In a development of the invention, it is also possible for the stop support to be designed in two parts and for each part of the stop support to be assigned a stop element. The double stop can thus be divided between two stop supports.

Furthermore, it has proven to be advantageous if the stop elements are arranged in such a way that they limit a rotary movement of the locking element to an angular range between 45 and 180 degrees, preferably between 60 and 150, particularly preferably between 75 and 120 and in particular to an angular range of 90 degrees limit. A 90 degree angle enables a reliable definition of the locked position and the unlocked position. The actuating element can also be moved in an angular range of 90 degrees, with one end of the angular range defining the unlocking position and the other end point of the angular range defining the locking position. It is also advantageous if latching points are provided which enable latching in the locked position and the unlocked position, so that the locking element can be reliably held in the two positions. When the locking element moves, the locking forces acting due to the locking points must first be overcome.

Furthermore, it has proven to be advantageous if the closure housing has an opening through which a shaft section of the actuating element extends. With this configuration, the actuating element can be mounted in the opening of the closure housing in a simple manner. If the lock housing is arranged on a door, the shaft portion can also extend through the door. Furthermore, the actuating element can be aligned with the breech housing in the mounted position, so that the actuating element does not protrude beyond the visible contour of the breech housing.

With regard to viewing the stop support, it has proven to be advantageous if it is arranged concentrically to the opening of the breech housing. The striker support may have an opening concentric with the opening of the breech housing and matching the size of the opening. In this way, the actuating element or the shaft section of the actuating element can also extend through the stop support. The stop support can be designed in the shape of a ring. The outer contour of the stop support can be polygonal, in particular octagonal. The stop support can be configured symmetrically, in particular point-symmetrically. The various mounting positions can be achieved by rotating the stop support about its axis of symmetry or about a locking axis extending centrally through the opening of the locking housing.

According to the invention, in order to connect the stop support to the breech housing, the stop support has a latching contour for the detachable connection to the breech housing. The stop carrier can be connected to the breech housing by hand in a simple manner and without the use of tools via the latching contour. The latching contour can be configured in such a way that it can enable the stop support to be connected to the breech housing in a preferably multiple predefined position. Furthermore, the latching contour can be designed in such a way that the stop support can be connected to the breech housing in a number of assembly positions.

Furthermore, it is provided that the closure housing also has a correspondingly designed latching contour for connection to the stop support. The latching contours of the breech housing and the stop support can be matched to one another in such a way that the stop support is arranged in different assembly positions on the breech housing can be. The latching contours of the stop carrier and/or the breech housing can have undercuts into which projections of the other latching contour can engage, so that the breech housing and the stop carrier can be positively connected to one another in different assembly positions. However, it is also possible for the stop support and the breech housing to be connected to one another in a non-positive manner via the latching contours.

According to the invention it is provided that the latching contours interact in the manner of a bayonet lock. The latching contours can interact in a simple manner via a bayonet lock. The stop support and the breech housing can thus be assembled in a simple manner by hand and without the use of any additional tools, or they can also be separated from one another again.

Furthermore, it has proven to be advantageous if the locking element is designed as a locking tongue, in particular as a latching tongue. A door can, for example, be securely locked in a simple manner using a locking tongue. The design of the locking element as a latching tongue results in very simple assembly or a very simple connection of the latching tongue to the actuating element.

It has proven to be advantageous if the locking element is releasably connected to the actuating element. A detachable connection means that the actuating element and the locking element can be stored separately from one another and only then connected to one another at the point of use in a very simple manner and without the use of tools become. Separating the two elements, for example to dismantle the breech, is also very easy due to a detachable connection. The actuating element can be connected to the locking element via a clip connection. Furthermore, the connection between the locking element and the actuating element can be designed in such a way that the locking element can move relative to the actuating element with one degree of freedom. Advantageously, this is a rotary movement, so that tolerances can be compensated for in a simple manner.

Furthermore, it has proven to be advantageous if the actuating element has a counter-stop against which the stop can strike when the actuating element is moved. The counter-stop can be designed as a double counter-stop and have one or more counter-stop elements. The counter-stop elements can each have one, in particular two, counter-stop surfaces. In the locked position and in the unlocked position, the counter-stop elements can bear against the stop elements. The number of counter-stop elements can match the number of stop elements. The counter-stop elements can be in the form of projections or cams and can extend in the radial direction. In an advantageous embodiment, two counter-stop elements are provided on opposite sides. The counter-stop elements can be arranged in the area of the shaft section, so that they can interact with the stop arranged on the stop carrier. The counter-stop elements and the stop elements can be designed in such a way that the stop and counter-stop surfaces that abut against one another lie flat on top of one another in the end positions, resulting in good force distribution.

Furthermore, it has proven to be advantageous if the actuating element has an interface. A force can be exerted on the actuating element via the interface, for example manually via a handle, a lever, a latch or a key. However, it is also possible for the actuating element to be actuated automatically, in particular electrically.

In a structural development of the invention, it is proposed to provide a sealing ring between the actuating element and the closure housing. Gas exchange can be reliably prevented via the sealing ring. Gas exchange can be reliably prevented by the seal, in particular when the door closes a space that is under overpressure or under underpressure. The seal can be designed as an O-ring.

With regard to the production of the closure, it has proven to be advantageous if the closure housing is produced by an in-mold process and is provided with a coating on its side opposite the locking element. The in-mold process allows the breech housing of the breech to be manufactured and coated in a very simple manner. The closure housing is made in particular from plastic. Alternatively, however, it is also possible to coat the breech housing in a separate step.

Furthermore, it has proven to be advantageous if the coating includes brushed stainless steel, chrome or a logo. The coating can improve the aesthetic appeal of the latch body. Furthermore, the coating can also have an inscription that indicates, for example, the direction of actuation or the space that is closed by the door.

With regard to the object mentioned at the outset, a door is also proposed which has a closure which is designed in the manner described above. The advantages already explained with regard to the closure result.

To connect the lock to the door, it has proven to be advantageous if the lock housing is connected to the door, in particular is releasably connected. The lock housing can, for example, be placed on the door and then screwed to the door.

In a further development of the door, it is proposed that the stop support be accommodated in the door in a non-rotatable manner. The door can be designed in such a way that the stop support can be accommodated in the door in a non-rotatable manner. The door can have a continuous recess which is designed in such a way that the stop support cannot twist. For assembly, the stop support can first be connected to the lock housing and the lock housing can then be arranged on the door in such a way that the stop support is received in the door in a non-rotatable manner. The outer contour of the stop support can be designed in such a way that it cannot twist in the recess of the door. The non-rotatable accommodation of the stop support enables the breech to be actuated reliably, so that the stop support cannot become detached from the breech housing when the closure element rotates. Before installing the lock, the door can be provided with a cam hole pattern, which can be adapted to the lock.

Further advantages and developments of the invention are to be explained in more detail below using an exemplary embodiment illustrated in the illustrations. Show in it:

In the representation of Fig. 1a a breech 1 is shown in an exploded view. The closure 1 can be used both for swing doors and for sliding doors or corresponding flaps, hatches or windows. In the following, however, the use of a door 8 designed as a pivoting door will be described as an example.

The closure 1 has a locking element 2, which is designed in the manner of a locking tongue, and an actuating element 3 which is rotatably coupled to the locking element 2 and via which the locking element 2 can be rotated about the locking axis V and thus actuated.

When the locking element 2 is actuated, it can be moved back and forth between a locked position and an unlocked position. In the locked position, this engages in one of the illustrations Fig. 1a not shown door 8 arranged locking element 2 in or behind an opposite of the door 8 fixed element, such as the door frame, so that the door 8 can no longer be opened. In order to open the door 8 again, the locking element 2 must be pivoted about the locking axis V into the unlocked position. In this position, the locking element 2 no longer blocks the door 8, so that it can be opened.

As shown in the exploded view in the Fig. 1a can further be seen, the locking element 2 is mounted on a breech housing 4 . The closure housing 4 has a circular opening 4.2 through which the actuating element 3 or an actuating shaft 3.2 of the actuating element 3 extends. Furthermore, the lock housing 4 is used to connect the actuating element 3 and the locking element 2 to the door 8, as is the case below with reference to FIG Figure 3b will be explained in more detail. In the exploded view of the Fig. 1a the door 8 would be arranged accordingly behind the lock housing 4.

In order to reliably move the locking element 2 into the unlocked position and the locked position, a stop 5.2 is provided, which in the exemplary embodiment is designed as a double stop with two stop elements 5.21, 5.22, each of which has two stop surfaces. The actuating element 3 has a counter-stop 3.1, which is designed as a double counter-stop with two counter-stop elements 3.11, 3.12, each with two counter-stop surfaces, so that in each end position, i.e. in the unlocked position or in the locked position, there is a counter-stop element 3.11, 3.12 on a stop element 5.21, 5.22 and further movement of the locking element 2 is prevented.

The position of the stop elements 5.21, 5.22 and the counter-stops 3.1, 3.2 thus not only determines the movement of the locking element 2, but also determines the installation situation in which the closure 1 can be used. Because, for example, the resulting attachment pattern cannot be used both for doors hinged on the right and for doors hinged on the left.

However, in order to use the same closure 1 variably in different installation situations, the stop 5.2 is arranged on a stop carrier 5, which is shown in the enlarged view in FIG 3 is shown. In the exemplary embodiment, this stop support 5 can be connected to the lock housing 4 in two different assembly positions, so that the same lock 1 can be used both for doors 8 hinged on the left and doors 8 hinged on the right.

The stop support 5 has two opposing stop elements 5.21 and 5.22, and can once in the assembly position according to Figure 4a with the breech housing 4 and once in the assembly position according to Figure 4b be connected to the breech housing 4.

The one in the Figure 4a The end position shown corresponds to either the locked position or the unlocked position and the counter-stop element 3.11 rests against the stop element 5.21. A clockwise rotation of the closure 2 or the actuating element 3 is not possible in this position. However, the actuating element 3 can be turned counterclockwise until the counter-stop element 3.11 rests against the lower stop element 5.22 and the corresponding counter-stop surface lies on the stop surface of the stop element 5.22. Like this it can also be seen that such a rotation corresponds to an angular change of the angle a of 90 degrees. The locking element 2 can thus be moved back and forth in a range of 90 degrees.

In order to distribute the acting forces, the counter-stop 3.1 has another counter-stop element 3.12, which is shown in the Figure 4a position shown rests against the stop element 5.22. If the actuating element 3 is pivoted counterclockwise, the counter-stop element 3.12 migrates to the stop element 5.21. Both counter-stop elements 3.11, 3.12 are therefore always in contact with one stop element 5.21, 5.22, both in the locked position and in the unlocked position.

In the Figure 4b another mounting position of the stop support 5 is shown. Because compared to in the Figure 4a In the assembly position shown, the stop support 5 has been rotated 90 degrees clockwise, resulting in a different stop pattern.

At the in Figure 4a The position shown is the locked position, so that the actuating element 3 must be pivoted counterclockwise in order to convert the locking element 2 into the unlocked position. In the Figure 4b On the other hand, the unlocked position is shown, so that it is necessary with this stop image to turn the actuating element 3 counterclockwise in order to convert it from the unlocked position into the locked position.

It will now be described below how the stop support 5 can be arranged in the various mounting positions on the breech housing 4 .

As is the case in the depictions of Figures 3a and 3b can be seen, both the stop carrier 5 and the breech housing 4 each have a latching contour 4.1, 5.1. The two latching contours 4.1, 5.1 are designed to correspond, so that the breech housing 4 and the stop support 4 can be detachably connected to one another via the latching contours 4.1, 5.1. The latching contour 5.1 has several circumferentially arranged undercuts that can reach behind the projections of the latching contour 4.1. The two latching contours 4.1, 5.1 can thus interact in the manner of a bayonet lock and the stop support 5 can be connected to the breech housing 4 in a form-fitting manner.

According to the illustration in Figures 3a and 3b the stop support 5 is first arranged over the latching contour 4.1 of the breech housing 4 for assembly. Then the stop support 5 is rotated relative to the breech housing 4, so that the two latching contours 4.1, 5.1 engage in one another and a form-fitting connection is established between the breech housing 4 and the stop support 5. Depending on which stop pattern is required, the stop support 5 can be rotated accordingly before it is pushed onto the latching contour 4.1 of the breech housing. In the present example, the two in the Figures 4a and 4b mounting positions shown with the associated mounting diagrams are possible.

So that the closure 1 can be arranged on the door 8, the door 8 must have a recess 8.1. This is in the Figure 3b to recognize. After the lock housing 4 has been connected to the stop carrier 5, this can be inserted into the recess 8.1 of the door 8. The recess 8.1 is adapted to the shape of the stop support 5. In this example, as shown in FIG 2 an octagonal basic shape and the recess 8.1 is designed in such a way that the stop support 5 cannot move in the recess 8.1 due to its geometric dimensions.

For the final assembly of the lock 1, the actuating element 3 can then be inserted into the lock housing 4 from one side, so that the shaft section 3.2 extends through the opening 4.2 in the lock housing 4, through the circular opening in the stop support 5 and also through the recess 8.1 in the door 8 extends.

In a next step, the locking element 2 can then be plugged onto the actuating element 3 from the opposite side. The actuating element 3 and the locking element 2 are detachably connected to one another via a clip connection. The composite closure 1 is shown in FIG Fig. 1b shown.
