Description

The invention relates to a latch closure system, comprising a lock arranged on a door leaf or can be arranged with a locking hook, with a locking device which is arranged or can be arranged on a frame part axis extending along a frame part of a door frame, wherein the locking device comprises a locking element, wherein the locking hook a rest position can be converted into a locking position and is locked or locked in its locking position with the locking element.

Such latch closure systems have been established in practice for locking door systems, such as gullwing doors or sliding doors. From the DE 20 2011 001 547 U1 Such a latch closure system is known.

In particular, bolt locking systems with locking hooks are installed in door systems in which increased safety, for example increased burglary protection, is required. The fact that the locking hook engages behind the frame-side locking element in the locked state, a levering of the door is difficult.

The present invention has for its object to provide a latch closure system that ensures high security with low installation and maintenance.

This object is achieved in a latch closure system of the aforementioned type according to the invention that the locking element is movably mounted along a first axis of movement parallel to the first axis of movement and that the locking element is subjected to force along the first axis of movement in the direction of a basic position.

According to the invention, it is possible that the relative position between locking hook and locking element may deviate from an ideal position, for example as a result of inaccurate mounting of the door leaf relative to the door frame or due to a gravitational "seating" of the door leaf relative to the door frame.

The latch closure system according to the invention is characterized in that the locking element is movably mounted along a first movement axis parallel to the frame part axis and that the locking element is subjected to 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 without the whole door system must be adjusted. The locking element may follow a displacement of the locking hook along the first axis of movement. It can thus always be ensured as complete as possible behind the locking hook.

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

In the latch closure system according to the invention is thus a complex initial assembly of the entire door system, which includes a high-precision relative positioning of locking hook and locking element, not required because any assembly inaccuracies can be compensated by means of the movable arrangement of the locking element.

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

It was inventively recognized that - apart from deviations from the ideal position due to inaccurate assembly - especially delayed changes in the relative position of the locking hook and the locking element, for example by a "setting" of the door panel, an increased security risk and high maintenance. If the door leaf "settles" under its own weight, ie shifts in the direction of gravity relative to the door frame, this has the consequence that an effective locking surface for a contact surface between the locking hook and the locking element changes over time and in particular can be reduced , Such a "setting" process is a slow, creeping process that can sometimes last for years. In order to always ensure a complete engagement behind the locking hook and thus a secure locking of the door, the latch closure system would have to be continuously checked and readjusted, which would be associated with high maintenance. The latch closure system according to the invention now makes it possible to effect such a displacement by "setting" the door leaf easy way to continuously balance, without requiring maintenance.

In a preferred embodiment, the locking hook on an abutment portion, which - along a transfer path of the locking hook from its rest position into its locking position, preferably before reaching the locking position - comes into contact with a contact surface of the locking element. This allows a reliable power transmission from the locking hook on the locking element upon transfer of the locking hook from its rest position to its locking position. It is particularly advantageous if the locking hook comes into contact with the contact surface of the locking element before reaching the locking position. As a result, a backlash-free connection between locking element and locking hook is ensured in the locked state and thus realized a particularly secure and reliable locking.

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

Furthermore, it is preferred if, in the locking position of the locking hook, the locking element along the first axis of movement and against the direction of force from its initial position in a deflected position is deflected. This applies in particular to the initial installation state of the door system. This makes it possible to continuously and instantaneously compensate displacements of the locking hook, in particular those displacements which arise over time, and thus always ensure complete engagement of the locking hook. The basic position of the locking hook and locking element is preferably selected at the initial installation of the door system so that the locking element is so far deflected in the locking position of the locking hook that the locking element can move at least over a Mindestweg away in the direction of its normal position, wherein the minimum path defines To what extent an undesirable change in the position of the locking hook in the direction of loading of the locking element, for example, as a result of a "setting" of the door leaf, compensated or compensated. The application of force ensures that the locking element is always in contact with the locking hook and can instantaneously follow an undesired displacement of the locking hook in the direction of application of force.

In order to compensate for a displacement of the locking hook by "setting" the door, in a further embodiment it is particularly preferred if the frame part axis and the first movement axis are oriented vertically or at least approximately vertically.

It is possible that the force application of the locking element is provided solely by the fact that the locking element has a dead weight and thus tends to move "down" with respect 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 pretensioning device has at least one spring, preferably in the form of a compression spring or tension spring. This makes it possible in a simple, cost-effective and at the same time reliable way to bias the locking element in the direction of its basic position.

It is further preferred if the locking device has a guide device for guiding the locking element along the first movement axis. This ensures that the locking element moves at least predominantly along the predetermined axis and that the locking element does not tilt along its path of movement. This also ensures a particularly secure and reliable function of the latch closure system.

In a further preferred embodiment, 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 easily and externally monitor whether the locking hook is correctly locked with the locking element and the door is securely locked. This is particularly advantageous for monitoring door systems in safety-relevant applications.

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 closing strip fastened or fastened to the frame part is provided, which is preferably arranged directly adjacent to the locking element. Such a closing strip, also referred to as a closing plate, can be designed as a metal sheet and provides additional protection against levering the door. The closing strip preferably has a passage opening into which the locking hook engages in its locking position. Preferably, the locking element is arranged directly adjacent to such a passage opening of the closing strip, so that the locking hook is displaceable through the passage opening into its locking position and lockable with the locking element.

A further preferred embodiment provides an adjusting device, by means of which a frame part-side position of the locking element transversely, in particular perpendicular, to a transfer plane of the locking hook, in which the locking hook can be transferred from the rest position into the locking position, is adjustable. 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 adjusting device makes it possible in a simple way to compensate for such deviations and to predetermine a desired position of the locking element relative to the frame part, in order to ensure a perfect engagement of the locking hook in the locking device, and thus a secure locking of the door. In this way, the latch closure system can be variably adapted to different door systems with low installation costs.

In a further preferred embodiment, the adjusting device has at least one eccentric element which 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 transversely to the transfer plane of the locking hook can be adjusted in a particularly simple manner. It is thus possible even after installation of the latch closure system without great installation effort, a relative displacement of the locking element and the Locking hook in a direction transverse to the transfer plane of the locking hook compensate.

In a further preferred embodiment, a fitting element arranged or arrangeable 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 immediately adjacent to the locking element and / or on which the above described biasing means, the above-described guide means, the above-described detection means and / or the adjusting device described above is or are arranged.

The invention further relates to a door system comprising a door leaf, a door frame and at least one latch closure system as described above, wherein the lock is 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 of the following description and the diagrammatic representation of a preferred embodiment.

Side views of an assembly of the latch closure systems according to Fig. 1 to 3 in different functional positions.

In FIG. 1 is a generally designated by the reference numeral 8 door system shown, which comprises a latch closure system 10. The latch closure 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 between a shown in the drawing, relative to the door frame 20 Position and an open position, not shown in the drawing movable, in particular pivotable.

In the drawing, a coordinate system is shown, which comprises mutually perpendicular axes x, y and z, wherein the z-axis of the coordinate system corresponds to a vertical axis with respect to the direction of gravity. The frame part axis 24 is parallel to the z-axis, ie also in the vertical direction. The door panel 12 extends substantially within a plane defined by the z-axis and by a horizontal y-axis; the x-axis also runs in the horizontal direction.

The locking device 22 comprises a fitting element 26, which is 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 panel 12 - the door lock 14 faces. The locking element 28 has a recess 34 which overlaps at least in sections with the opening 32 of the fitting element 26. On the side facing away from the fitting element 26 side of the locking element 28, a closing strip 36 is provided; the locking element 28 is thus arranged between the fitting element 26 and the closing strip 36. The closing strip 36 is fastened to the frame part 18 and overhangs the locking element 28, which thus does not detach from the fitting element 26 when viewed in the y-direction.

The closing strip 36 has a passage opening 38, which is arranged adjacent to the recess 34 of the locking element 28 and at least partially overlapped with this.

It is possible that no closing strip 36 is provided. In this case, it is preferable for the fitting element 26 to have holding sections which engage over the locking element 28, so that the locking element 28, as seen in the y direction, is fastened to the fitting element 26.

The locking hook 16 of the door lock 14 has an abutment portion 40 and an angled, preferably vertical locking portion 42 for this purpose. The locking hook 16 is when locking the door lock 14 from a rest position (in FIG. 2 indicated by dashed lines) about a pivot axis 41 and in a transfer plane (Y / Z plane in FIG FIG. 2 ) transferred into a locking position. This position of the locking hook 16 is in FIG. 2 shown by solid lines.

In the locked state, the locking hook 16 passes 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 lock 14 is within the receiving space 30 of the fitting element 26 arranged. In this case, the locking hook 16 engages with its locking portion 42 a locking surface 44 facing away from the door lock 14 of the locking element 28. Thus, a levering of the door leaf 12 is counteracted, in particular in a direction perpendicular to the contact surface between the locking portion 42 and the locking surface 44 (ie in the negative Y direction).

In an ideal position of the locking hook 16 engages with its locking portion 42, the locking surface 44 of the locking element 28 completely, so that the contact surface between locking portion 42 and 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 each other in its locking position, that the locking hook 16 in its locking position with its contact portion 40 with an angle to the locking surface 44, preferably vertical contact surface 46 of the locking element 28 in Plant stands.

The locking element 28 is movably mounted along a first movement axis 48 parallel to the frame part axis 24. As a result, deviations from the ideal position, for example as a result of a "seating" of the door leaf 12, can be compensated, 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, which by "setting" the door leaf in the direction of Gravity "down" (ie in the negative z-direction) can occur, the frame part axis 24, and thus the movement axis 48, preferably vertically aligned (see FIG. 1 ). The locking hook 16 pivots preferably starting from its rest position "upwards" (ie in the positive Z direction) in the locking position.

The locking element 28 is by means of a biasing device 50 in the direction of a basic position ("position 0" in FIG. 4 and 5 ) and is held in the unlocked state, for example, in the open position of the door leaf 12, in this basic position. From this basic position, the locking element 28 along the first movement axis 48 and against the Kraftbeaufschlagungsrichtung (ie in the positive Z direction) can be deflected, but at most up to a stop position ("position 1" in FIG. 4 and 5 ).

When transferring the locking hook 16 from its rest position to its locking position of the locking hook 16, before reaching its locking position, with its contact portion 40 into contact with the contact surface 46 of the, initially in its normal position, locking element 28 Upon further pivoting of the locking hook 16 is the locking element 28 against the Kraftbeaufschlagungsrichtung and in the "closing direction" of the locking hook 16 (ie in the positive Z direction) along the first movement axis 48 deflected and, upon reaching the locking position of the locking hook 16, by the locking hook sixteenth 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" (ie in the negative Z direction), which displacement would reduce the contact surface 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 reaching his basic position. The locking element 28 is always held in contact with the abutment portion 40 of the locking hook 16 by the force acting against the "closing direction" (ie in the negative Z direction) with its contact surface 46. The locking element 28 and the locking hook 16 thus remain relative to each other in an ideal position. This ensures that - even with a displacement of the locking hook 16 - the locking portion 42 of the locking hook 16 always completely engages behind the locking surface 44 of the locking element 28.

For guiding the locking element 28 along the first movement axis 48, the fitting element 26 has a guide device 52, which preferably has mutually parallel guide sections 54 which cooperate with corresponding guide surfaces 56 of the locking element 28.

The biasing device 50 comprises, for example, two springs 58, which are preferably designed as compression springs and which, for example, in the region of Guide portion 54 of the fitting element 26 or adjacent thereto are arranged. 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 receiving surface 61 of the locking element 28 so that it is pressed in the direction of its basic position ("position 0"), cf. Fig. 3 and 4 ,

In the FIG. 5 an assembly of another embodiment of a latch closure system 10 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 FIGS. 1 to 4 described components can be used. The module 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") to a position deviating from this basic position, a deflected position.

The detection device 60 is formed for example by a switch or a latch-switching 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 normal position. If, during a locking process, the locking element 28 is deflected out of its basic position by the locking hook 16 - the locking element 28 is thus no longer in contact with the sensor surface 64 - this is how it is Signal sent to a display system and displayed the changed lock status of the door system.

The latch closure system 10 further comprises an adjustment device 68, cf. FIGS. 3 to 6 , This serves to adjust a frame part-side position of the locking element 28 and also of the fitting element 26 relative to the closing strip 36. The adjustment direction is transverse, in particular perpendicular, to the transfer plane of the locking hook 16 (ie 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 closing strip 36 and held there rotatable about the respective axes 70. The eccentric elements 72 each have a shaft 74 which protrudes from the eccentric head and cooperates with the locking element 28 and the fitting element 26. The shaft 74 is radially spaced from the central axis 70 of the eccentric member and connectable at its free end to a counterpart 76.

The respective shaft 74 engages in a backdrop-shaped material recess 78 of the fitting element 26 and cooperates there with mutually parallel contact sections 80 which bound the material recess 78. Upon rotation of the eccentric elements 72 about the central axis 70, the respective shaft 74 of an eccentric element 72 transmit a force to one of the contact portions 80, so that the fitting element 26 is deflected from an initial position transversely, in particular vertically, to the transfer plane of the locking hook 16. The distance of the contact portions 80 is slightly larger than the thickness of the shaft 74.

The locking element 28 likewise has adjusting sections 82 which, in the same way as the contact sections 80 of the fitting element 26, can cooperate with the respective shaft 74 of the eccentric elements 72, provided that the spacing of the adjusting sections 82 is slightly wider than the thickness of the shaft 74.

In the embodiment shown in the drawing, the locking element 28 is forcibly guided on the fitting element 26 via the guide device 52, so that the locking element 28 follows a deflection of the fitting element 26 transversely, in particular vertically, to the transfer plane of the locking hook 16. Therefore, the distance of the adjusting portions 82 is chosen so large that they do not collide with a rotation of an eccentric portion 72 with the shaft 74.

The purpose of the adjustment of the position of the locking element 28 in its x-direction described above 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 not with the lateral edges of the recess 34 collides (with a lateral Touching the edges of the recess 34, although not preferred, is possible).

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

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

In FIG. 6c are the fitting element 26 and the locking element 28 in its second, opposite to the first extreme position extreme position.
