Description

The invention relates to a bolt locking system with a lock with a locking hook that is or can be arranged on a door leaf, with a locking device which is or can be arranged on a frame part of a door frame extending along a frame part axis, the locking device having a locking element, the locking hook from can be transferred from a rest position to a locking position and is locked or locked in its locking position with the locking element.

Such bolt locking systems have become established in practice for locking door systems, for example wing doors or sliding doors. From the DE 20 2011 001 547 U1 such a bolt locking system is known.

In particular, bolt locking systems with locking hooks are installed in door systems where increased security, for example increased protection against break-ins, is required. The fact that the locking hook engages behind the frame-side locking element in the locked state makes levering out the door more difficult.

A bolt lock system with the features of the preamble of claim 1 is from JP 2001 342766 A known.

The present invention is based on the object of providing a bolt locking system which ensures a high level of security with little assembly and maintenance effort.

This object is achieved according to the invention in a bolt locking system with the features of the preamble of claim 1 by the characterizing features of claim 1.

According to the invention it is possible that the relative position between the locking hook and the locking element can deviate from an ideal position, for example as a result of inaccurate assembly of the door leaf relative to the door frame or as a result of gravity "settling" of the door leaf relative to the door frame.

The bolt locking system according to the invention is characterized in that the bolt element is movably mounted along a first movement axis parallel to the frame part axis and that the bolt element is acted upon by force along the first movement axis in the direction of a basic position. Due to the movable mounting of the locking element, deviations from an ideal position of the locking hook relative to the locking element, for example as a result of inaccurate installation of the door leaf relative to the door frame, can be easily compensated for without the entire door system having to be adjusted. The locking element can follow a displacement of the locking hook along the first axis of movement. It is thus always possible to ensure that the locking hook is gripped as completely as possible.

As a result of the application of force, the locking element is held in a basic position in the unlocked state. This makes it possible for the locking hook to engage behind the locking element when it is transferred into its locking position and to lock it with it. In addition, any rattling of the locking element is prevented in the unlocked state, for example when the door is open.

In the case of the bolt locking system according to the invention, a complex initial assembly of the entire door system, which a highly accurate relative positioning of the locking hook and locking element is not required, since any assembly inaccuracies can be compensated by means of the movable arrangement of the locking element.

There is also no need for regular inspection or maintenance of the door system, since the movable arrangement of the locking element also makes it possible to compensate for changes in the relative position of the locking hook and locking element that occur over time.

It was recognized according to the invention that - apart from deviations from the ideal position due to imprecise assembly - in particular time-delayed changes in the relative position of the locking hook and the locking element, for example by "setting" the door leaf, represent an increased safety risk and high maintenance costs. If the door leaf "settles" under its own weight, ie moves in the direction of gravity relative to the door frame, this has the consequence that a contact surface between the locking hook and the locking element that is effective for locking changes over time and can in particular decrease in size . Such a "setting" process is a slow, creeping process that can sometimes last for years. In order to ensure that the locking hook is always fully grasped behind and thus that the door is securely locked, the bolt locking system would have to be continuously checked and readjusted, which would be associated with high maintenance costs. The The bolt locking system according to the invention now makes it possible to continuously compensate for such a shift by "setting" the door leaf in a simple manner, without this requiring maintenance.

According to the invention, the locking hook has a contact section which - along a transfer path of the locking hook from its rest position to its locking position, before reaching the locking position, comes into contact with a contact surface of the locking element. This enables a reliable transmission of force from the locking hook to the locking element when the locking hook is transferred from its rest position to its locking position. The locking hook comes into contact with the contact surface of the locking element before the locking position is reached. This ensures a backlash-free connection between the locking element and the locking hook in the locked state, and thus a particularly secure and reliable locking is achieved.

For reliable locking, it is provided that the locking hook has a locking section which, at least in the locking position of the locking hook, engages behind a locking surface of the locking element.

In the locking position of the locking hook, the locking element is also along the first Axis of movement and deflected against the direction of force application from its basic position into a deflected position. This makes it possible to continuously and instantaneously compensate for displacements of the locking hook, in particular such displacements that occur over time, and thus always ensure that the locking hook is fully engaged behind. The basic position of the locking hook and the locking element is preferably selected during the initial assembly of the door system so that the locking element is deflected in the locking position of the locking hook so far that the locking element can move at least over a minimum distance in the direction of its basic position, the minimum distance defining the extent to which an undesired change in the position of the locking hook in the direction in which the force is applied to the locking element, for example as a result of the door leaf being "set", can be compensated for. The application of force ensures that the locking element is always in contact with the locking hook and can instantly follow an undesired displacement of the locking hook in the direction of application of force.

According to the invention, the locking device has a detection device which detects a deflection of the locking element from its basic position into a deflected position. This makes it possible to monitor from the outside in a simple manner whether the locking hook is properly locked with the locking element and the door is securely locked. This is particularly advantageous for monitoring door systems in security-relevant areas of application.

In order to compensate for a displacement of the locking hook by "setting" the door, it is particularly preferred in a further embodiment if the frame part axis and the first movement axis are vertical or are at least approximately vertically oriented. It is possible that the application of force to the locking element is provided solely by the fact that the locking element has its own weight and thus tends to move "downwards" in relation to the direction of gravity. In a preferred embodiment, however, the locking device has a pretensioning device for applying force to the locking element.

In a further preferred embodiment, the prestressing device has at least one spring, preferably in the form of a compression spring or tension spring. This makes it possible, in a simple, inexpensive and at the same time reliable manner, to pretension the locking element in the direction of its basic position.

It is also preferred if the locking device has a guide device for guiding the locking element along the first axis of movement. This ensures that the locking element moves at least primarily along the specified axis and that the locking element does not tilt along its path of movement. This also ensures a particularly safe and reliable function of the bolt locking system.

The detection device preferably has at least one contact sensor which has at least one sensor surface which is in contact with at least one contact surface of the locking element when the locking element is in its basic position. With such an arrangement, a deflection of the locking element from its basic position can be detected in a particularly reliable and robust manner.

In a further preferred embodiment, a locking strip fastened or fastenable to the frame part is provided, which is preferably arranged directly adjacent to the locking element. Such a locking bar, also referred to as a locking plate, can be designed as sheet metal and offers additional protection against the door being pried open. The locking bar preferably has a passage opening into which the locking hook engages in its locking position. The locking element is preferably arranged directly adjacent to such a passage opening of the locking strip, so that the locking hook can be displaced through the passage opening into its locking position and locked with the locking element.

Another preferred embodiment provides an adjusting device by means of which a frame part-side position of the locking element can be set transversely, in particular perpendicular, to a transfer plane of the locking hook in which the locking hook can be transferred from the rest position to the locking position. Deviations from a predetermined relative position between the locking element and the locking hook in a direction transverse to the transfer plane of the locking hook can arise, for example, through the use of different profile systems or rubber seals. The setting device makes it possible in a simple manner to compensate for such deviations and to specify a target position of the locking element relative to the frame part in order to ensure proper engagement of the locking hook in the locking device and thus secure locking of the door. In this way, the bolt locking system can be variably adapted to different door systems with little installation effort.

In a further preferred embodiment, the setting device has at least one eccentric element that can be rotated about an eccentric axis. In the course of a rotation of the at least one eccentric element, the position of the locking element can be set in a particularly simple manner transversely to the transfer plane of the locking hook. Thus, even after the bolt locking system has been installed, it is possible to move the locking element and the Compensate locking hook in a direction transverse to the transfer plane of the locking hook. In a further preferred embodiment, a fitting element which is arranged or can be arranged on the frame part of the door frame is provided which has a receiving space in which the locking hook engages at least in its locking position and / or which is arranged directly adjacent to the locking element and / or on which the above described pretensioning device, the above-described guide device, the above-described detection device and / or the above-described setting device is or are arranged.

The invention also relates to a door system with a door leaf, a door frame and at least one bolt lock system described above, the lock being arranged on the door leaf and the locking device on a frame part of the door frame extending along a frame part axis.

Further features and advantages of the invention are the subject matter of the following description and the drawing of a preferred exemplary embodiment.

Side views of an assembly of the bolt locking systems according to Figs. 1 to 3 in various functional positions.

In Figure 1 a door system, denoted as a whole by the reference number 8, is shown, which comprises a bolt locking system 10. The bolt locking system 10 comprises a door lock 14 arranged on a door leaf 12 of the door system 8 with a locking hook 16 and a locking device 22 arranged on a frame part 18 of a door frame 20 of the door system 8. The frame part 18 extends along a frame part axis 24.

The door leaf 12 is closed relative to the door frame 20 between a position shown in the drawing Position and an open position not shown in the drawing movable, in particular pivotable.

The drawing also shows a coordinate system which comprises mutually perpendicular axes x, y and z, the z-axis of the coordinate system corresponding to an axis that is vertical in relation to the direction of gravity. The frame part axis 24 runs parallel to the z-axis, ie also in the vertical direction. The door leaf 12 extends essentially within a plane spanned by the z-axis and a horizontal y-axis; the x-axis also runs in the horizontal direction.

The locking device 22 comprises a fitting element 26 arranged on the frame part 18 of the door frame 20 and fastened there, and a locking element 28, cf. Figures 2 and 3 . The fitting element 26 has a receiving space 30 and an opening 32. This is - in the closed position of the door leaf 12 - facing the door lock 14. The locking element 28 has a recess 34 which at least in sections overlaps with the opening 32 of the fitting element 26. A locking strip 36 is provided on the side of the locking element 28 facing away from the fitting element 26; the locking element 28 is thus arranged between the fitting element 26 and the locking strip 36. The locking bar 36 is fastened to the frame part 18 and overlaps the locking element 28, which therefore does not detach from the fitting element 26 when viewed in the y direction.

The locking strip 36 has a passage opening 38 which is arranged adjacent to the recess 34 of the locking element 28 and at least in sections overlaps it.

It is possible that no locking bar 36 is provided. In this case it is preferred if the fitting element 26 has holding sections which overlap the locking element 28, so that the locking element 28 is fastened to the fitting element 26 as seen in the y-direction.

The locking hook 16 of the door lock 14 has a contact section 40 and a locking section 42 angled thereto, preferably perpendicular thereto. When the door lock 14 is locked, the locking hook 16 is moved from a rest position (in Figure 2 indicated with dashed lines) about a pivot axis 41 and in a transfer plane (Y / Z plane in Figure 2 ) transferred into a locking position. This position of the locking hook 16 is in Figure 2 shown with solid lines.

In the locked state, the locking hook 16 extends through the passage opening 38 of the locking bar 36 and the recess 34 of the locking element 28 and the opening 32 of the fitting element 26. The part of the locking hook 16 facing away from the locking section 42 of the door lock 14 is within the receiving space 30 of the fitting element 26 arranged. The locking hook 16 with its locking section 42 engages behind a locking surface 44 facing away from the door lock 14 of the locking element 28. This counteracts the levering out of the door leaf 12, in particular in a direction perpendicular to the contact surface between the locking section 42 and the locking surface 44 (that is, in the negative Y direction).

In an ideal position, the locking hook 16 with its locking section 42 completely engages behind the locking surface 44 of the locking element 28, so that the contact area between the locking section 42 and the locking surface 44 is maximized and a particularly high level of protection is ensured. The ideal position is when the locking element 28 and the locking hook 16 are positioned relative to one another in its locking position so that the locking hook 16 in its locking position with its contact section 40 with a contact surface 46 of the locking element 28 at an angle to the locking surface 44, preferably perpendicular Plant stands.

The locking element 28 is mounted movably along a first movement axis 48 parallel to the frame part axis 24. In this way, deviations from the ideal position, for example as a result of the door leaf 12 being "set", can be compensated for, and it can be ensured that the locking section 42 of the locking hook 16 always fully engages behind the locking surface 44 of the locking element 28.

In particular, to compensate for such shifts caused by "setting" the door leaf in the direction of the Gravity "downwards" (that is, in the negative z-direction), the frame part axis 24, and thus the movement axis 48, are preferably oriented vertically (cf. Figure 1 ). The locking hook 16 preferably swivels starting from its rest position "upwards" (that is, in the positive Z direction) into the locking position.

The locking element 28 is in the direction of a basic position ("position 0" in Figure 4 and 5 ) is acted upon by force and is held in the unlocked state, for example with the door leaf 12 in the open position, in this basic position. From this basic position, the locking element 28 can be deflected along the first movement axis 48 and counter to the direction of application of force (that is, in the positive Z direction), but at most up to a stop position ("position 1" in FIG Figure 4 and 5 ).

When the locking hook 16 is moved from its rest position into its locking position, the locking hook 16, before reaching its locking position, comes with its contact section 40 in contact with the contact surface 46 of the locking element 28, which is initially in its basic position. When the locking hook 16 is pivoted out further the locking element 28 is deflected against the direction of application of force and in the "closing direction" of the locking hook 16 (that is, in the positive Z direction) along the first movement axis 48 and, when the locking hook 16 has reached the locking position, by the locking hook 16 preferably held in an intermediate position between the basic position and the stop position.

In the case of a displacement of the locking hook 16 in a direction opposite to the "closing direction" (i.e. in the negative Z-direction), which displacement would reduce the contact area between the locking hook 16 and the locking element 28, the locking element 28 follows the displacement of the locking hook 16, at least until it reaches its basic position. The locking element 28 is always held with its contact surface 46 in contact with the contact section 40 of the locking hook 16 by the force acting against the "closing direction" (that is, in the negative Z direction). The locking element 28 and the locking hook 16 thus remain in an ideal position relative to one another. This ensures that - even when the locking hook 16 is displaced - the locking section 42 of the locking hook 16 always fully engages behind the locking surface 44 of the locking element 28.

To guide the locking element 28 along the first movement axis 48, the fitting element 26 has a guide device 52, which preferably has guide sections 54 which are parallel to one another and which interact with corresponding guide surfaces 56 of the locking element 28.

The pretensioning device 50 comprises, for example, two springs 58, which are preferably designed as compression springs and which, for example, in the area of one Guide section 54 of the fitting element 26 or are arranged adjacent thereto. A first end of a spring 58 is supported on a support surface 59 of the fitting element 26; an opposite end of a spring 58 acts on a force-absorbing surface 61 of the locking element 28, so that this is pressed in the direction of its basic position ("position 0"), cf. Fig. 3 and 4th .

In the Figure 5 an assembly of an embodiment of a bolt locking system 10 according to the invention is shown. This assembly comprises on the frame part 18 of the door frame 20 fixable components, which instead of the above with reference to the Figures 1 to 4 components described can be used. The assembly according to Fig. 5 additionally has a detection device 60 which detects a deflection of the locking element 28 from its basic position ("position 0") into a deflected position deviating from this basic position.

The detection device 60 is formed, for example, by a switch or a bolt switch contact. The detection device 60 preferably has a contact sensor 62, also referred to as a button or opener, which has a sensor surface 64. This is in contact with a contact surface 66 of the locking element 28 when the locking element 28 is in its basic position. If the locking element 28 is deflected from its basic position by the locking hook 16 during a locking process - that is, the locking element 28 is no longer in contact with the sensor surface 64 - a Signal sent to a display system and the changed locking status of the door system displayed.

The bolt locking system 10 further comprises an adjusting device 68, cf. Figures 3 to 6 . This serves to set a position on the frame part side of the locking element 28 and also of the fitting element 26 relative to the locking strip 36. The adjustment direction runs transversely, in particular perpendicular, to the transfer plane of the locking hook 16 (that is, along an axis parallel to the X-axis of the coordinate system shown).

The adjusting device 68 preferably comprises two eccentric elements 72 which can be rotated about a central axis 70. The eccentric elements 72 are arranged with an eccentric head on receptacles 73 of the locking bar 36 and are held there so as to be rotatable about the respective axes 70. The eccentric elements 72 each have a shaft 74, which protrudes from the eccentric head and interacts with the locking element 28 and the fitting element 26. The shaft 74 is spaced apart radially from the central axis 70 of the eccentric element and can be connected at its free end to a counterpart 76.

The respective shaft 74 engages in a link-shaped material recess 78 in the fitting element 26 and interacts there with mutually parallel contact sections 80 which delimit the material recess 78. When the eccentric elements 72 rotate about the central axis 70, the respective shaft 74 becomes an eccentric element 72 transmit a force to one of the contact sections 80, so that the fitting element 26 is deflected from an initial position transversely, in particular perpendicularly, to the transfer plane of the locking hook 16. The distance between the contact sections 80 is slightly greater than the thickness of the shaft 74.

The locking element 28 also has adjustment sections 82 which, in the same way as the contact sections 80 of the fitting element 26, can interact with the respective shaft 74 of the eccentric elements 72, provided the distance between the adjustment sections 82 is slightly wider than the thickness of the shaft 74.

In the embodiment shown in the drawing, the locking element 28 is positively guided via the guide device 52 on the fitting element 26, so that the locking element 28 follows a deflection of the fitting element 26 transversely, in particular perpendicular, to the transfer plane of the locking hook 16. The distance between the adjustment sections 82 is therefore selected to be so large that they do not collide with the shaft 74 when an eccentric section 72 rotates.

The purpose of the above-described setting of the position of the locking element 28 in its x-direction is to position the recess 34 of the locking element 28 in the x-direction so that the recess 34 is aligned with the transfer plane of the locking hook 16 and the locking hook 16 is not collides with the lateral edges of the recess 34 (with a lateral Touching the edges of the recess 34 is not preferred, but possible).

The Figures 6a, 6b, 6c show side views of an assembly of an embodiment of the bolt locking system 10 in different functional positions. In Figure 6a the locking device 22, comprising the fitting element 26 and the locking element 28, is in a basic position relative to the locking bar 36, which is central with respect to the X-axis. The receiving space 30 of the fitting element 26 and the recess 34 of the locking element 28 are therefore centered with respect to the passage opening 38 of the closing strip 36 is positioned along the X-axis. The eccentric elements 72 of the adjusting device 68 are positioned in an initial rotational position around the eccentric axis 70 so that the respective shaft 74 is located on a central axis 84 of the locking bar 36 that is parallel to the movement axis 48 and the Z axis of the coordinate system shown. The two eccentric elements 72 are preferably rotated by 180 ° relative to one another.

In Figure 6b the locking device 22 is in a first extreme position relative to the locking strip 36. In this first extreme position, the fitting element 26 and the locking element 28 are in a position that is maximally deflected from their basic position in the positive X direction. The two eccentric elements 72 of the adjusting device 68 are here rotated from their initial rotational position, in each case in the opposite direction, by 90 ° around the eccentric axis 70, so that the respective shaft 74 is in a position spaced apart from the central axis 84 in the positive X direction.

In Figure 6c the fitting element 26 and the locking element 28 are in their second extreme position opposite to the first extreme position.
