Description

The invention relates to a trap assembly for a lock and a lock with the trap assembly.

Fallen arrangements are usually used in a lock and serve to hold the door leaf in the attack or in the strike plate. The trap arrangement presented here comprises two mirror-image trap heads arranged one above the other. This design is also called "cross latch" and is for example in EP 2 706 174 A2 described. In particular, for so-called "panic locks" this design is used.

The two trap heads allow unlocking and locking the door in both transverse directions, ie door movement directions. When the latch shaft is blocked, the lock is positively locked in both transverse directions. If the trap shaft is not blocked, the lock is unlocked in both transverse directions.

Furthermore, the two case heads can serve for pressure relief of locking elements in the transverse direction by the two case heads have a width which is greater than the width of the locking element. This ensures that the closing force of the door is taken over the case heads by the strike plate comes to rest on the case heads, while the locking element relative to the strike plate is free to move and thus pressure relieved. Thus, the locking element can be retracted force minimal by pressing the lock from the strike plate, and only on a last path section when retracting the locking element in the housing of the castle the case heads are unlocked, so that they can be automatically pushed back into the housing, for example by the door is manually moved away from the strike plate.

It is an object of the present invention to provide a trap assembly with two latch heads that can be safely unlocked even at high preload on the door panel and / or while avoiding signs of wear.

The object is achieved by the features of the independent claims. The dependent claims relate to advantageous embodiments of the invention.

• Die Fallenanordnung wird insbesondere im Gehäuse eines Schlosses angeordnet. Das Schloss wiederum wird vorzugsweise in einem Türblatt montiert. Das Gehäuse des Schlosses umfasst vorzugsweise den Schlosskasten. Auch der Schlossstulp, welcher üblicherweise am Schlosskasten und/oder Türblatt befestigt, insbesondere angeschraubt, wird, ist Bestandteil des Gehäuses.

Thus, the invention is solved by the following trap arrangement:

• The trap arrangement is arranged in particular in the housing of a lock. The lock in turn is preferably mounted in a door leaf. The housing of the lock preferably comprises the lock case. The lock forend, which is usually attached to the lock case and / or door leaf, in particular screwed, is part of the housing.

To describe the invention three mutually perpendicular axes are defined: a vertical vertical axis, a transverse axis and a longitudinal axis. The transverse axis runs parallel to the two directions of door movement. Along the longitudinal axis, the movement of the trap assembly into and out of the housing takes place. A transverse direction is defined parallel to the transverse axis. A longitudinal direction is defined parallel to the longitudinal axis.

The trap assembly comprises a latch shaft. This is adapted to be movably arranged in the housing of the lock along the longitudinal axis. In particular, the fall shaft arranged linearly movable along the longitudinal axis. However, it is also possible to design the latch shaft in such a way that it executes a pivot movement with a movement vector along the longitudinal axis in the housing of the lock.

Furthermore, the trap arrangement comprises two trap heads. The first case head is pivotally attached to the latch shaft. The first case head is pivotable or rotatable relative to the latch shaft about a first pivot axis.

The second case head is also pivotally attached to the latch shaft. The second case head is pivotable or rotatable relative to the latch shaft about a second pivot axis.

The two pivot axes are parallel to each other and parallel to the vertical axis. The two pivot axes are spaced apart. An axial distance between the two pivot axes is therefore greater than 0. This center distance is defined in a plane perpendicular to the vertical axis, in particular parallel to the transverse axis.

The trap arrangement is, unless otherwise stated, always described in the basic position. In the basic position, the case heads protrude out of the housing of the lock and are not loaded in the transverse direction.

Each trap head of the trap assembly preferably has an active surface. The two trap heads are preferably arranged so that the two active surfaces face outward.

Each trap head of the trap assembly preferably has a passive surface. The active surface and the passive surface are, when viewed on a plane perpendicular to the vertical axis, wedge-shaped and thus at an acute angle to each other. When moving the door in In particular, always an active surface (of the one case head) and then a passive surface (of the other case head) come into contact with the striking plate in the transverse direction.

Due to the load in the transverse direction on the respective active surface of the respective case head pivots about its pivot axis relative to the latch shaft. In particular, the case head is pivoted so far until its active surface is parallel to the passive surface of the other case head. As a result, the active surface of the pivoted case head and the passive surface of the non-pivoted case head together form a wedge surface. The stress in the transverse direction on this wedge surface leads to a force component along the longitudinal direction and thus to a displacement of the entire trap assembly in the housing of the castle.

Preferably, complementary abutment surfaces are formed on the respective case head and on the latch shaft, which abut each other when the case head is pivoted so far until its active surface is parallel to the passive surface of the other case head.

The attachment of the respective case head on the case shaft preferably takes place via a pivot pin which extends from the latch shaft parallel to the vertical axis. In the case head a corresponding hole for receiving the pivot pin is formed. However, the pivotal arrangement of the case head on the case shaft can also be done otherwise, for example, by a firmly connected to the case head pin which is in a hole of the trap shaft.

The center distance according to the invention between the two pivot axes allows design freedom in the design of the kinematics of the trap assembly. So it is particularly possible, the respective pivot axis with the greatest possible distance, measured parallel to the transverse direction, to arrange the active area of the same case head.

It is preferably provided that the first and second pivot axes are spaced transversely to the vertical axis, wherein preferably a straight line defined perpendicular to both pivot axes extends parallel to the transverse axis.

The axial distance between the two pivot axes is preferably at least 2 mm, more preferably at least 3 mm, particularly preferably at least 4 mm.

Furthermore, the advantageous center distance can be determined as a function of the width of the individual case head. The width of the drop head is measured parallel to the transverse axis and at its widest point. The center distance is preferably at least 5%, more preferably at least 10%, particularly preferably at least 15%, of this width. The two trap heads are preferably formed the same width.

As already described, each case head has an outwardly facing active surface. Preferably, the active surface abuts against the strike plate, even before the passive surface of the other case head touches the strike plate. Preferably, the two active surfaces are in the basic position of the trap assembly parallel to each other. Furthermore, it is preferably provided that the respective active surface is perpendicular to the transverse direction in the basic position.

The two active surfaces are spaced apart by a certain width, measured parallel to the transverse axis. In particular, this distance of the two active surfaces corresponds to the greatest width of the individual case head. So the "width" is defined by: The distance of the both active surfaces and / or the largest width of the individual case head, each measured parallel to the transverse axis.

Parallel to the transverse axis, an "active surface distance" is defined at each case head: an active surface distance is defined from the first pivot axis to the active surface of the first case head; a further active surface distance is defined by the second pivot axis to the active surface of the second case head.

It is preferably provided that the two active surface distances are each greater than half the width. The pivot axis of the respective case head is thus not in the middle of the case head. Furthermore, therefore, the pivot axis of the respective case head is spaced more than half the width of the associated active surface.

Preferably, the two active surface distances are equal, so that the same kinematics result for both case heads.

It is preferably provided that the two case heads are identical.

Each of the trap heads has a back. The back is facing a tip of the trap heads. The trap heads protrude with the tip out of the case. In particular, the active area and the passive area of the case head meet at the top of the case head.

It is preferably provided that the ridges are each designed such that a width extension of the case heads, measured parallel to the transverse axis, remains in the untwisted position during pivoting of the case heads within the width extent of the case heads. Particularly preferably, the backs are rounded.

Preferably, each of the two case heads has a support edge. The support edge is parallel to the vertical axis and is of the respective Spaced pivot axis. If the trap assembly is installed in the housing of the lock, the support edge is located on an inside of the housing, in particular on the inside of the lock plate on.

Preferably, each case head has a contact surface. This contact surface is preferably perpendicular to the longitudinal direction. When installed, the contact surface is inside the case and points outwards. The support edge is preferably an edge of this contact surface.

In the installed state of the trap assembly forms the support edge by their investment on the housing a support axis. The respective case head is pivotable or rotatable about this support axis relative to the housing. When loaded in the transverse direction on the active surface of the case head, the case head pivots relative to the latch shaft about its pivot axis. At the same time, the case head pivots about its support axis relative to the housing. As a result, the pivotal movement of the latch head leads to a force acting on the latch shaft, directed longitudinally force component. This force component shifts the trap assembly into the interior of the housing. Here, the pivot axes move.

It is preferably provided that a first angle is formed between the active area of the first drop head and a straight line which leads through the support edge of the first drop head and through the first pivot axis. A second angle is formed between the active area of the second drop head and a straight line passing through the support edge of the second drop head and through the second pivot axis.

Particularly preferably, the first angle corresponds to the second angle.

It is preferably provided that the first angle is greater than a third angle between the active area of the first drop head and a straight line passing through the support edge of the first drop head and through a center point on a line connecting the two pivot axes, and / or the second angle greater than a fourth angle between the active area of the second drop head and a straight line passing through the support edge of the second drop head and through a center point on a line connecting the two pivot axes. The first, second, third and / or fourth angle may in particular be an acute angle. As a result, the forces acting on the trap assembly, can be favorably influenced and thus counteracted wear.

Two support distances are defined parallel to the transverse axis: a support distance is defined by the first pivot axis to the height of the support edge of the first case head; another support distance is defined by the second pivot axis to the height of the support edge of the second case head. It is preferably provided that the support distance of the respective case head is equal to or shorter than the active surface distance of the same case head. Preferably, based on the transverse axis, the support edge of the respective case head between the pivot axis and the active surface or at the same height as the active surface of the same case head.

Preferably, the support distance is at least 90%, particularly preferably at least 95%, of the active surface distance of the same case head.

Furthermore, the support distance is preferably greater than half the width. Preferably, the support distance is at least 102%, more preferably at least 105%, half the width. The "width" is how already defined, the distance between the two active surfaces and / or the width of the individual case head, measured in each case parallel to the transverse axis.

The center distance between the pivot axes according to the invention allows both a relatively large active surface distance (from the active surface to the pivot axis) and a relatively large support distance (from the support axis to the pivot axis). The large support distance acts, with a load in the transverse direction on the active surface, as a lever arm for the stroke or the linear movement of the latch shaft along the longitudinal axis and thus into the interior of the housing.

Preferably, it is provided that the first and the second pivot axis are offset from each other such that a force with which the pivot axes are moved back by a pressure at least on the active surface of a case head in a housing of the castle is less than a hypothetical force with the the pivot axes would be moved back by a pressure at least on the active surface of a case head in the housing of the lock, if the pivot axes would be arranged parallel to the vertical axis one above the other on a line connecting the pivot axes. In each case the same pressure acts on the active surface. By the displacement of the pivot axes wear can be effectively prevented.

Preferably, it is provided that the first and the second pivot axis are offset from each other in such a way that a force with which the support edge relative to the rest of the lock, in particular the housing, particularly preferably the lock plate, supported as soon as a pressure is exerted on the active surface, is less than a hypothetical force with which the supporting edge would be supported relative to the rest of the lock, when the pivot axes parallel to the vertical axis on one another on a pivot axes connecting Line would be arranged. The hypothetical force arises at the same pressure on the active surface. As a result, wear on the supporting edge can be prevented.

Preferably, it is contemplated that the first and second pivot axes are offset from one another such that a force acting on a trap blockage device as pressure is applied to the active surface is less than a hypothetical force applied to the blockage device would act to block the case when the pivot axes would be arranged parallel to the vertical axis one above the other on a line connecting the pivot axes. The hypothetical force arises at the same pressure on the active surface. Such a displacement of the pivot axes can prevent wear on the blocking device and on the latch shaft and a lighter opening can be achieved under high preload.

The invention further comprises a lock, in particular designed as a panic lock. The lock according to the invention comprises the latch arrangement according to the invention, as well as the latch arrangement according to the invention is described in the description and in the claims.

The lock preferably comprises a housing. The housing comprises in particular the lock case and the lock forend. In particular, the described case arrangement is located in the housing. The case heads preferably protrude out of the housing in the basic position.

Preferably, the lock comprises a spring which is supported on the housing and the latch shaft. The spring pushes the latch shaft along the longitudinal axis to the outside. Due to the force of the spring is the Fall shaft, as far as no other forces acting on him, in its basic position and protrudes from the housing to the outside.

Preferably, the lock comprises at least the blocking device for blocking the latch shaft in its basic position. The blocking device can be operated mechanically and / or electrically. In the locked position, the large support distance has a favorable effect on the load on the latch shaft.

The latch assembly is preferably arranged in the housing so that the two latch heads are each pivotable about a support axis relative to the housing. The respective support axis is formed in particular by the support edges described above, which abut against the inside of the housing, in particular the lock tulip. However, it is also possible to design the support axes and thus the rotatability of the individual case head with respect to the housing otherwise.

Regardless of the structural design of the support axis, the two support distances are defined parallel to the transverse axis: the one support distance is defined by the first pivot axis to the support axis of the first case head; the further support distance is defined by the second pivot axis to the support axis of the second case head. The advantageous embodiments of these support distances have already been described with reference to the trap arrangement.

a detail from FIG. 6 ,

The figures show an embodiment of a lock 1 with a latch assembly 5. In the figures, each perpendicular to each other, a vertical axis 40, a transverse axis 41 and a longitudinal axis 42 are shown as a Cartesian coordinate system.

FIG. 1 shows the lock 1 with its housing 2. The housing 2 includes a lock case. Also, a Schlossstulp 3 is here part of the housing 2. The lock plate 3 is firmly connected to the rest of the housing. The lock plate 3 is connectable to the door leaf.

The trap arrangement 5 is located in the housing 2. The latch arrangement 5 protrudes from the housing 2 in its basic position along the longitudinal direction 42.

Other components of the lock 1, such as a blocking device for blocking the trap assembly 5, a follower or a lock cylinder are not shown for clarity, but can be arranged in the housing 2 of the lock 1.

The trap assembly 5 comprises a latch shaft 6, a first latch head 8 and a second latch head 9.

In the housing 2, a spring support 4 is formed. Between this spring support 4 and the latch shaft 6, a spring 7 is arranged. The spring 7 presses the latch assembly 5 in the basic position shown.

The latch shaft 6 is guided linearly movable in the housing 2 along the longitudinal direction 42. For this purpose, a guide slot 10 is formed in the housing 2. In this guide slot 10 is a guide extension 24 ( FIG. 6 ) of the trap 6.

For a clear representation of the trap assembly 5 is in FIG. 3 the lock plate 3 hidden. In FIG. 4 In addition, the two case heads 8, 9 are hidden. FIG. 5 shows only the fall shaft 6. In FIG. 6 the housing 2 of the lock 1 is hidden; only the latch assembly 5, the spring support 4 and the spring 7 are shown. FIG. 7 shows an enlarged detail FIG. 6 ,

In the following, reference is made to all figures.

The latch shaft 6 comprises a first pivot pin 11 and a second pivot pin 12. The first pivot pin 11 extends upwards along the vertical axis 40. The second pivot 12 extends down the vertical axis 40.

Each of the two case heads 8, 9 has a hole. The first pivot pin 11 is inserted in the hole of the first case head 8. The second pivot pin 12 is inserted in the hole of the second case head 9. As a result, the first case head 8 is pivotable about a first pivot axis 13 with respect to the latch shaft 6. The second case head 9 is pivotable about a second pivot axis 14 with respect to the latch shaft 6. The two pivot axes 13, 14 are parallel to the vertical axis 40.

In particular FIGS. 4 and 5 show, the two pivot axes 13, 14 with an axial distance 22 spaced from each other. The axial distance 22 is defined here parallel to the transverse axis 41.

Each of the two case heads 8, 9 has an active surface 15 and an opposite passive surface 16. In particular FIG. 6 shows that the active surface 15 to the passive surface 16 of the same case head 8, 9 is at an acute angle. The two active surfaces 15 point outward with respect to the transverse axis 41 and are parallel to one another. Furthermore, the two active surfaces 15 are perpendicular to the transverse axis 41. The passive surfaces 16 are in particular parallel to the vertical axis 40 and are inclined with respect to the transverse axis 41 and the longitudinal axis 42.

Such as the Figures 2 and 3 show stop surfaces 19 are formed on the case heads 8, 9 and 6 on the fall shaft. The stop surfaces 19 limit the pivoting of the respective case head 8, 9 with respect to the latch shaft 6.

In particular FIG. 3 shows that each of the two case heads 8, 9 has a contact surface 17. The contact surface 17 is perpendicular to the longitudinal axis 42. The contact surface 17 forms a support edge 18, wherein the support edge 18 that edge of the contact surface 17 which is parallel to the vertical axis 40 and the associated active surface 15 is closest.

The contact surface 17 and the support edge 18 are in the normal position on the inside of the lock plate 3. Thus, the support edge 18 forms a support axis 23 about which the respective case head 8, 9 relative to the housing 2 is pivotable or rotatable. When pivoting the case head 8, 9 lifts the contact surface 17 from the inside of the housing, the support edge 18 remains on the inside in Appendix and rolls on the inside. When pivoting the case head 8, 9 of the case head is rotated about the pivot axis 13, 14, wherein at the same time the pivot axes 13, 14 are moved into the interior of the housing 2.

• Eine Breite 25, die sowohl den Abstand zwischen den beiden Aktivflächen 15 als auch die größte Breite des einzelnen Fallenkopfs 8, 9 beschreibt; jeweils parallel zur Querachse 41 definiert.

In particular FIGS. 6 and 7 show the following:

• A width 25, which describes both the distance between the two active surfaces 15 and the largest width of the individual case head 8, 9; each defined parallel to the transverse axis 41.

The distances of the respective active surface 15 to the associated pivot axis 13, 14 of the same case head 8, 9 are shown as active surface distances 26. Parallel to the respective active surface distance 26, the support distance 20 from the respective support axis 23 to the pivot axis 13, 14 of the same case head 8, 9 is measured. The support distance is defined parallel to the transverse axis 41.

By the axial distance 22 between the two pivot axes 13, 14, both the active surface distance 26 and the support distance 20 can be made relatively large.

A load in the transverse direction on the active surface 15 of a case head 8, 9 acts with respect to the support shaft 23 with a lever arm 21. The torque generated by the lever arm 21 about the support shaft 23 leads to a corresponding force on the latch shaft 6 in the direction of the longitudinal axis 42, the relatively large support distance 20 acts as a lever. As a result, the resulting force on the latch shaft 6 can be kept low. This can prevent wear on the support edge 18.

FIG. 7 also shows on the basis of the second case head 9 that a second angle α is formed between the active surface 15 of the second case head 9 and a straight line which leads through the support edge 18 of the second case head 9 and through the second pivot axis 14. Not shown, is a corresponding first angle α formed between the active surface 15 of the first drop head 8 and a straight line passing through the support edge 18 of the first drop head 8 and through the first pivot axis 13. The size of the first angle α corresponds to the size of the second angle α.

Furthermore, in FIG. 7 shown that the second angle α is greater than a fourth angle β between the active surface 15 of the second drop head 9 and a straight line passing through the support edge 18 of the second drop head 9 and through a center 43 on a line connecting the two pivot axes 13, 14 leads. Analogous and not shown, the first angle α is greater than a third angle β between the active surface 15 of the first drop head 8 and a straight line passing through the support edge 18 of the first drop head 8 and through a center 43 on one of the two pivot axes 13, 14 connecting line leads.
