Description

DESCRIPTION

Latch arrangement of a lock

The invention relates to a latch arrangement for a lock, as well as to a lock with the latch arrangement.

Latch arrangements are commonly used in a lock and serve to hold the door leaf abutted or on the strike. The latch arrangement presented herein comprises two latch heads arranged as an inverted image one above the other. This type of construction is also called "cross latch" and is described for example in EP 2 706 174 A2. This type of construction is used in particular for so-called "panic locks".

The two latch heads allow unlocking and locking of the door in both transverse directions, that is, the directions of movement of the door. In the case of a locked bolt stem, the lock is positively locked in both transverse directions. When the latch rod is not locked, the lock is unlocked in both transverse directions.

Furthermore, the two bolt heads can serve for pressure relief of bolt elements in the transverse direction, the two bolt heads having a width which is greater than the width of the bolt element. In this way, it is achieved that the closing force of the door is absorbed by the bolt heads, reaching the strike to settle against the bolt heads, while the bolt element is freely movable with respect to the strike and, therefore, pressure released. In this way, the bolt element can be removed by actuation of the bolt lock with minimal force and the bolt heads are not unlocked until a final stretch of travel when the bolt element is withdrawn into the lock housing , so that these can be automatically pulled back into the housing, for example by moving the door manually in the direction away from the strike.

The object of the present invention is to show a latch arrangement with two latch heads that can be safely unlocked, also in the event of a high preload on the door leaf and / or by avoiding wear phenomena.

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

Therefore, the invention is achieved by the following latch arrangement:

The latch arrangement is arranged in particular in the housing of a lock. The lock in turn is preferably mounted on a door leaf. The lock housing preferably comprises the lock box. Also the lock plate, which is usually fixed to the lock box and / or to the door leaf, in particular by means of screws, forms part of the housing.

In order to describe the invention, three axes are defined that extend perpendicular to each other: a vertical axis, a transverse axis and a longitudinal axis. The transverse axis extends parallel to the two directions of movement of the door. Along the longitudinal axis, movement of the latch arrangement into the housing 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 latch arrangement comprises a latch stem. This is made to be movably arranged along the longitudinal axis inside the lock housing. In particular, the latch rod is arranged linearly movable along the longitudinal axis. However, it is also possible to make the latch rod in such a way that it performs a pivotal movement with a movement vector along the longitudinal axis inside the lock housing.

Furthermore, the latch arrangement comprises two latch heads. The first latch head is pivotally attached to the latch stem. The first latch head is pivotal or rotatable relative to the latch stem about a first pivot axis.

The second latch head is also pivotally fixed on the latch stem. The second latch head is pivotal or rotatable relative to the latch stem about a second pivot axis. The two pivot axes are each arranged one parallel to the other and parallel to the vertical axis. The two pivot axes are arranged at a distance from each other. A distance between axes between the two pivot axes is therefore greater than 0. This distance between axes is defined in a plane perpendicular to the vertical axis, in particular parallel to the transverse axis.

The latch arrangement is always described in the base position, unless otherwise indicated. In the home position, the latch heads protrude from the lock housing and are not loaded in the transverse direction.

Each latch head of the latch arrangement preferably has an active surface. The two latch heads are preferably arranged such that the two active surfaces face outward.

Each latch head of the latch arrangement preferably has a passive surface. The active surface and the active surface are arranged in the form of a wedge and therefore at an acute angle to each other when viewed from a plane perpendicular to the vertical axis. In the case of a door movement in the transverse direction, in particular an active surface (of one latch head) and then a passive surface (of the other latch head) always come into contact with the strike.

Thanks to the load in the transverse direction on the corresponding active surface, the corresponding latch head pivots around its pivot axis relative to the latch rod. In particular, the latch head also pivots until its active surface is arranged parallel to the passive surface of the other latch head. In this way, the active surface of the pivoted latch head and the passive surface of the non-pivoted latch head together form a wedge surface. The load 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 latch arrangement into the lock housing.

Preferably, complementary abutment surfaces are formed on the corresponding latch head and on the latch rod, which abut against each other when the latch head has been pivoted until its active surface is parallel to the passive surface of the other head. latch.

The fixing of the corresponding latch head on the latch stem is preferably done by means of a pivot which extends from the latch stem parallel to the vertical axis. A corresponding hole is made in the latch head for housing the pivot. However, the pivoting arrangement of the latch head on the latch stem can also be realized in another way, for example by means of a stub fixedly connected to the latch head which is inserted into a hole in the latch stem.

The center distance according to the invention between the two pivot axes allows configuration freedoms when performing the kinematics of the latch arrangement. In particular, thanks to this it is possible to arrange the pivot axis corresponding to the greatest possible distance, measured in parallel to the transverse direction of the active surface of the same bolt head.

Preferably, provision is made for the first and second pivot axes to be arranged at a distance in the transverse direction relative to the vertical axis, preferably a defined line extending in the direction perpendicular to the two pivot axes parallel to the transverse axis.

The distance between the axes between the two pivot axes is preferably at least 2 mm, also preferably at least 3 mm, especially preferably at least 4 mm.

Furthermore, the advantageous wheelbase can be determined as a function of the width of the individual latch head. The width of the latch head is measured parallel to the transverse axis and at its widest point. The distance between axes preferably corresponds to at least 5%, more preferably at least 10%, especially preferably at least 15% of this width. The two latch heads are preferably made of the same width.

As already described above, each latch head has an outward facing active surface. Preferably, the active surface abuts against the striker even before the surface of the other latch head comes into contact with the striker. Preferably, the two active surfaces are arranged parallel to one another in the home position of the latch arrangement. Furthermore, it is preferably provided that the corresponding active surface is arranged in the base position in the direction perpendicular to the transverse direction.

The two active surfaces are arranged at a distance corresponding to a given width, measured parallel to the transverse axis. In particular, this distance between the two active surfaces corresponds to the largest width of the individual latch head. The "width" is therefore defined by: the distance between the two active surfaces and / or the largest width of the individual latch head, respectively measured parallel to the transverse axis.

Parallel to the transverse axis, a "distance between the active surfaces" is defined in each latch head: a distance between the active surfaces is defined from the first pivot axis to the active surface of the first latch head; another distance between the active surfaces is defined from the second pivot axis to the active surface of the second latch head.

Preferably, the two distances between the active surfaces are each greater than half the width. The pivot axis of the corresponding latch head is therefore not arranged in the center of the latch head. Furthermore, therefore, the pivot axis of the corresponding latch head has a distance greater than half the width of the corresponding active surface.

Preferably, the two distances between the active surfaces measure the same, so that the same kinematics results for the two latch heads.

Preferably, it is provided that the two bolt heads are made identically.

Each of the latch heads has a back. The back is opposite a tip of the latch heads. The latch heads protrude with the tip of the housing. In particular, the active surface and the passive surface of the latch head coincide at the tip of the latch head.

Preferably, it is provided that the backs are each made in such a way that an extension of the width of the latch heads measured parallel to the transverse axis is held in the non-pivoted position as the latch heads pivot in the width extension. of the latch heads. The backs are particularly preferably rounded.

Preferably, each of the two latch heads has a supporting edge. The support edge is arranged parallel to the vertical axis and is arranged at a distance from the corresponding pivot axis. When the latch arrangement is mounted in the lock housing, the abutment edge bears against an inner side of the housing, in particular against the inner side of the lock plate.

Preferably, each latch head has a contact surface. This contact surface is preferably arranged in the direction perpendicular to the longitudinal direction. In the assembled state, the contact surface is located on the inside of the housing and faces outwards. The supporting edge is preferably an edge of this contact surface.

In the assembled state of the latch arrangement, the bearing edge forms a bearing axis by its contact with the housing. The corresponding latch head is pivotal or rotatable about this bearing axis with respect to the housing. In the event of a load in the transverse direction on the active surface of the latch head, the latch head pivots about its pivot axis relative to the latch stem. At the same time, the latch head pivots about its bearing axis relative to the housing. In this way, the pivotal movement of the latch head leads to a force component acting on the latch rod, oriented in the longitudinal direction. This component of force moves the latch arrangement into the housing. At the same time the pivot axes move.

Preferably, provision is made for a first angle to be formed between the active surface of the first latch head and a straight line passing through the bearing edge of the first latch head and through the first pivot axis. A second angle is formed between the active surface of the second latch head and a straight line that passes through the bearing edge of the second latch head and through the second pivot axis.

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

Preferably, provision is made for the first angle to be greater than a third angle between the active surface of the first latch head and a straight line passing through the bearing edge of the first latch head and through a center in a line connecting the two pivot axes and / or that the second angle is greater than a fourth angle between the active surface of the second latch head and a straight line that passes through a bearing edge of the second latch head and through a center in a line connecting the two pivot axes. The first, second, third and / or fourth angle can in particular be an acute angle. In this way, the forces acting on the latch arrangement can be favorably influenced, thereby counteracting wear.

Two support distances are defined parallel to the transverse axis: a support distance is defined from the first pivot axis at the height of the support edge of the first latch head; Another bearing distance is defined by the second pivot axis at the bearing edge of the second bolt head. Preferably, provision is made for the bearing distance of the corresponding latch head to be equal to or shorter than the distance between the active surfaces of the same latch head. Preferably, the bearing edge of the corresponding latch head is arranged relative to the transverse axis between the pivot axis and the active surface or at the same height as the active surface of the latch head itself.

Preferably, the contact distance corresponds to at least 90%, especially preferably at least 95% of the distance between the active surfaces of the same latch head.

Furthermore, the abutment distance is preferably greater than half the width. Preferably the abutment distance corresponds to at least 102%, particularly preferably at least 105% of the half of the width. As already defined above, the "width" is the distance between the two active surfaces and / or the width of the individual latch head, measured in each case parallel to the transverse axis.

The wheelbase according to the invention between the pivot axes allows both a relatively large distance from the active surface (from the active surface to the pivot axis) and also a relatively large bearing distance (from the bearing axis to the pivot axis). pivoting). The large bearing distance acts in the event of a load in the transverse direction on the active surface as a lever arm for the linear travel or movement of the latch rod along the longitudinal axis and thus into the housing.

Preferably, it is provided that the first and second pivot axes are offset relative to each other in such a way that a force with which the pivot axes can be moved backwards by pressure at least on the active surface of a latch head to the interior of the lock housing less than a hypothetical force with which the pivot axes could be moved backwards by pressure at least on the active surface of a latch head inside the lock housing, if the axes pivot axes were arranged parallel to the vertical axis one above the other in a line connecting the pivot axes. In this case, the same pressure acts on the active surface. Due to the displacement of the pivot shafts, wear can be effectively prevented.

Preferably, provision is made for the first and second pivot axes to be offset relative to each other in such a way that a force with which the bearing edge abuts relative to the remaining lock, in particular relative to the housing, in particular compared to the lock plate, is less than a hypothetical force with which the bearing edge would bear with respect to the remaining lock as soon as pressure is exerted on the active surface, if the pivot axes were arranged parallel to the vertical axis one above the other in a line connecting the pivot axes. The hypothetical force is formed when the same pressure is exerted on the active surface. In this way, wear on the supporting edge can be prevented.

Preferably, provision is made for the first and second pivot axes to be offset relative to each other in such a way that a force acting on a locking device to lock the latch is less than a hypothetical force that would act on the locking device to locking the latch when the pivot axes are arranged parallel to the vertical axis one above the other in a line joining the pivot axes as soon as pressure is exerted on the active surface. The hypothetical force is generated with the same pressure on the active surface. Thanks to such a displacement of the pivot axes, wear on the locking device and on the latch rod can be prevented and an easier opening can be achieved under high preload.

The invention further comprises a lock, designed in particular as an anti-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 which 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 plate. In the housing in particular the described latch arrangement is found. Preferably, the latch heads protrude in the base position of the housing.

Preferably, the lock comprises a spring that bears against the housing and the latch rod. The spring biases the latch stem outward along the longitudinal axis. Thanks to the force of the spring, the latch rod is in its base position when no other forces act on it and protrudes out of the housing.

Preferably, the lock comprises at least the locking device for locking the bolt rod in its base position. The locking device can be mechanically and / or electrically actuated. In the locked position, the large contact distance has a favorable effect on the load acting on the latch rod. The latch arrangement is preferably arranged in the housing such that the two latch heads can each pivot about a bearing axis relative to the housing. The corresponding bearing axis is formed in particular by the above-described bearing edges, which bear against the inside of the housing, in particular the lock plate. However, it is also possible to configure the support shafts and thus the possibility of turning the individual latch head relative to the housing in a different way.

Regardless of the constructional configuration of the support shaft, two support distances are defined parallel to the transverse axis: a support distance is defined by the first pivot axis of the support axis of the first latch head; the other support distance is defined by the second pivot axis of the support axis of the second latch head. The advantageous configurations of these support distances have already been described with the aid of the latch arrangement.

For the lock according to the invention the following characteristics are in particular provided:

(A) Lock, comprising a housing and a latch arrangement arranged in the housing, as described above.

(B) Lock according to point (A), comprising a spring supported on the housing and on the latch stem, urging the latch stem outward for movement along the longitudinal axis. (C) Lock according to one of the points (A) or (B), each of the two bolt heads being pivoting around a support axis with respect to the casing, the corresponding support axis being displaced with respect to the axis of pivoting of the bolt head itself in parallel, although in the direction of the longitudinal axis, in particular the pivot axes being further away from the bolt rod than the support axes. The pivot axes are in particular in the longitudinal direction more outward than the support axes.

(D) Lock according to point (C), two support distances being defined parallel to the transverse axis: one from the first pivot axis to the support axis of the first latch head and one from the second pivot axis to the axis support of the second bolt head, each bolt head having an outwardly facing active surface to abut against a strike, two distances of the active surfaces being defined parallel to the transverse axis: one from the first pivot axis to the surface of the first latch head and one of the second pivot axis to the active surface of the second latch head, the bearing distance of the corresponding latch head being equal to or shorter than the distance of the active surface thereof latch head.

(E) Lock according to one of the points (C) or (D), being defined parallel to the transverse axis two support distances: one of the first pivot axis at the height of the support axis of the first bolt head and one of the second pivot axis at the height of the support axis of the second bolt head, each bolt head having an outwardly facing active surface to abut against a strike, the two active surfaces being arranged at a distance of one width measured parallel to the transverse axis, each of the two distances greater than half the width.

The invention will be explained in more detail below with the aid of an exemplary embodiment. They show: Figure 1 a schematic view of a lock according to the invention with a latch arrangement according to the invention according to the exemplary embodiment,

The Figures show an exemplary embodiment of a lock 1 with a latch arrangement 5. In the Figures, a vertical axis 40, a transverse axis 41 and a longitudinal axis 42 are respectively represented perpendicular to one another as a Cartesian coordinate system.

Figure 1 shows the lock 1 with its housing 2. The housing 2 comprises a lock box. A lock plate 3 also forms part of the housing 2. The lock plate 3 is firmly connected to the remaining housing. The lock plate 3 can be connected to the door leaf.

In the housing 2 there is the latch arrangement 5. The latch arrangement 5 protrudes in its base position along the longitudinal direction 42 of the housing 2.

Other components of the lock 1, such as for example a locking device for locking the latch arrangement 5, a latch nut or a locking cylinder are not shown for clarity, although they may be arranged in the housing 2 of the lock 1.

The latch arrangement 5 comprises a latch stem 6, a first latch head 8, and a second latch head 9.

A spring bearing 4 is formed in the housing 2. Between this spring bearing 4 and the latch rod 6 a spring 7 is arranged. The spring 7 presses the latch arrangement 5 into the base position shown.

The latch rod 6 is guided in a linearly movable manner along the longitudinal direction 42 in the housing 2. For this purpose, a guide groove 10 is formed in the housing 2 10. A guide extension 24 is guided in this guide groove 10 ( Figure 6) Latch Stem 6.

For a clear representation of the latch arrangement 5, in Figure 3 the lock plate 3 is omitted. In Figure 4 the two latch heads 8, 9 are further omitted. Figure 5 shows only the latch stem 6 In Figure 6 the casing 2 of the lock 1 is omitted; only the latch arrangement 5, the spring bearing 4 and the spring 7 are shown. Figure 7 shows an enlarged detail of Figure 6.

In the following, reference is made to all the Figures.

The latch stem 6 comprises a first pivot 11 and a second pivot 12. The first pivot 11 extends along the vertical axis 40 upward. The second pivot 12 extends along the vertical axis 40 downward. Each of the two latch heads 8, 9 has a hole. In the hole of the first latch head 8 the first pin 11 is inserted. In the hole of the second latch head 9 the second pin 12 is inserted. Thus, the first latch head 8 is pivotable around a first pivot axis 13 with respect to latch stem 6. The second latch head 9 is pivotal about a second pivot axis 14 relative to latch stem 6. The two pivot axes 13, 14 are arranged parallel to the vertical axis 40 .

As Figures 4 and 5 show in particular, the two pivot axes 13, 14 are arranged at a distance between axes 22 from each other. The distance between axes 22 is defined here parallel to the transverse axis 41.

Each of the two latch heads 8, 9 has an active surface 15 and an opposite passive surface 16. In particular, Figure 6 shows that the active surface 16 is arranged at an acute angle to the passive surface 16 of the same latch head 8, 9. The two active surfaces 15 are oriented outward with respect to the transverse axis 41 and they are arranged in parallel to each other. Furthermore, the two active surfaces 15 are arranged in the direction perpendicular to the transverse axis 41. The passive surfaces 16 are arranged in particular parallel to the vertical axis 40 and are inclined relative to the transverse axis 41 and relative to the longitudinal axis 42.

As FIGS. 2 and 3 show, for example, on the latch heads 8, 9 and on the latch rod 6 abutment surfaces 19 are produced. The abutment surfaces 19 limit the pivoting of the corresponding latch head 8, 9 with respect to to the latch stem 6.

In particular, Figure 3 shows that each of the two latch heads 8, 9 has a contact surface 17. The contact surface 17 is arranged in the direction perpendicular to the longitudinal axis 42. The contact surface 17 forms a bearing edge 18, bearing edge 18 being the edge of the contact surface 17 which is arranged parallel to the vertical axis 40 and which is arranged closer to the corresponding active surface 15.

The contact surface 17 and the bearing edge 18 rest in the basic position against the inner side of the lock plate 3. The bearing edge 18 thus forms a bearing axis 23 around which the bolt head 8 , 9 correspondingly is pivotal or rotatable with respect to the housing 2. As the latch head 8, 9 pivots, the contact surface 17 rises from the inner side of the housing, the bearing edge 18 on the inner side being in contact and rolling on the inside side. As the latch head 8, 9 pivots, the latch head rotates about the pivot axis 13, 14, the pivot axes 13, 14 moving into the housing 2 at the same time.

In particular, Figures 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 latch head 8, 9; defined in each case parallel to the transverse axis 41.

The distances of the corresponding active surface 15 from the corresponding pivot axis 13, 14 of the same latch head 8, 9 are shown as distances between active surfaces 26. In parallel to the corresponding active surface distance 26, the distance of support 20 of the corresponding support axis 23 of the pivot axis 13, 14 of the same latch head 8, 9. The support distance is defined parallel to the transverse axis 41.

By means of the center distance 22 between the two pivot axes 13, 14 both the distance between the active surfaces 26 and the bearing distance 20 can be configured relatively large.

A load in the transverse direction on the active surface 15 of a latch head 8, 9 acts with a lever arm 21 relative to the support axis 23. The torque generated with the lever arm 21 around the support axis 23 leads to a corresponding force on the latch rod 6 in the direction of the longitudinal axis 42, the relatively large bearing distance 20 acting as a lever. In this way, the resultant force on the latch rod 6 can be kept low. In this way, wear on the supporting edge 18 can be prevented.

Figure 7 also shows, with the aid of the second latch head 9, that a second angle a is formed between the active surface 15 of the second latch head 9 and a straight line that passes through the support edge 18 of the second latch head. latch 9 and by the second pivot axis 14. A corresponding first angle a is not represented, which is formed between the active surface 15 of the first latch head 8 and a straight line passing through the bearing edge 18 of the first head of latch 8 and by the first pivot axis 13. The measure of the first angle a corresponds to the measure of the second angle a.

Furthermore, it is shown in Figure 7 that the second angle a is larger than a fourth angle p between the active surface 15 of the second latch head 9 and a straight line passing through the bearing edge 18 of the second latch head. 9 and by a center 43 on a line joining the two pivot axes 13, 14. Similarly, the first angle a is greater than a third angle p between the active surface 15 of the first latch head 8 and a straight that passes through the bearing edge 18 of the first latch head 8 and through a center 43 in a line joining the two pivot axes 13, 14, although this angle is not represented.
