Description

The present invention relates to a locking device for the wing of a door or a window, in particular a revolving door or a sliding door, with a guide rail, a displaceable in the guide rail or minimally displaceable, but shock absorbing, sliding element and a non-displaceably arranged in the guide rail locking element, which cooperates via a coupling element with the sliding element for locking the wing in a predetermined open position.

To determine a door equipped with a door closer with guide rail door is often a so-called sliding block, which is moved when opening and closing the door in the guide rail, held. This is usually done via a spring-loaded, laterally engaging on the sliding block latching means which engages at a certain door angle in a recess on the sliding block. If you want to close the door, a user must draw with considerable force on the door handle or the door, so that the spring-biased locking means can be released again from its locked position and thus releases the locking means the door.

These locking devices have the disadvantage that the release usually creates a loud, disturbing noise. Furthermore, by the constant engagement and disengagement of the locking means wear and damage to the sliding block and the locking means arise. In addition, the known locking devices have the disadvantage that they must be adapted to the closing force of the door closer. Because if the transferred from the locking means on the sliding block holding force is too weak, the door is not reliably held. On the other hand, an excessive holding force leads to increased noise pollution and an increased force required to close the door.

The invention has for its object to provide a locking device for the wing of a door or a window, which can be solved quiet and low-wear.

The object is achieved by a locking device with the features of claim 1 and in particular by the fact that the coupling element operatively connected to the sliding element and on the locking element, a guide element, in particular a slotted guide is provided or vice versa, wherein the guide element defines a guideway through which the Coupling element with a coupling portion at the opening of the wing first on the locking position and subsequent movement of the wing in the closing direction in a predetermined opening position corresponding latching position and moving the wing in the opening direction is moved to a release position again.

The door is released by the inventive determination by a relatively light, short press in the opening direction largely noiseless. An adjustment of a holding force, as is necessary in the above-described locking devices with locking means eliminated.

Advantageous embodiments can be found in the subclaims, the description and the drawings.

According to an advantageous embodiment, the guide element has an end-side inlet opening. The entrance opening is arranged on the side of the guide element from which the coupling element approaches the guide element when the sash is opened. The page is dependent on whether the coupling element is connected to the sliding element or the locking element.

Furthermore, according to one embodiment, the guide element is closed on the side opposite the input, so that the coupling element with the coupling section can be moved only a short distance beyond the predetermined open position. As a short distance, for example, a distance between 1 cm and 5 cm can be designated. Such an embodiment is advantageous if the door should be detectable in exactly one locking position.

Alternatively, the guide element may have an exit opening. The exit opening is arranged on the side in the direction of which the coupling element moves when the sash is opened. The outlet opening ensures that an opening movement of the wing is not limited by the guide element. This embodiment is useful, for example, if the door should be detectable in several locking positions. For this purpose, a plurality of locking elements are preferably arranged one behind the other along a guide rail, each of which can define a locking position.

According to one embodiment, the exit opening is arranged in the guide element in the course of the guideway in front of the detent position.

Alternatively or additionally, the exit opening can be arranged in the guide element in the course of the guideway to the detent position. The output opening can thus in the course of the guideway exclusively to the detent position be arranged. But it is also possible that in each case an exit opening is arranged in the course of the guideway before and after the detent position.

So that the coupling section can move as freely as possible along the guide track of the guide element, the coupling element preferably comprises a pivoting arm equipped with the coupling section, which is pivotable about a pivot axis which is perpendicular to the plane of the guide rail. Guide rails are typically channel-shaped, i. they have two substantially vertical guide surfaces and a horizontal surface connecting the guide surfaces. In this case, the footprint defines the plane of the guide rail.

As an alternative to the last-mentioned embodiment with the swivel arm, the coupling element may have a rotatable disk equipped with the coupling section, wherein the disk is rotatable about an axis of rotation which is perpendicular to the plane of the guide rail. This embodiment is particularly useful if the structurally required distance between the coupling portion and the axis of rotation is small.

As a third alternative, the coupling element can have a carriage equipped with the coupling section, which can be moved transversely to the direction of displacement of the sliding element and parallel to the plane of the guide rail.

For easy attachment of a closer lever of a door closer to the sliding element, the sliding element may comprise a perpendicular to the plane of the guide rail aligned bolt, which is connectable to the closer lever of the door closer.

According to an embodiment in which the coupling element is connected to the sliding element, the coupling element is rotatable or pivotable about the longitudinal axis of the bolt. For example, the bolt can be rotatably mounted in the sliding element and the coupling element rotatably connected to the bolt. Alternatively, the bolt may be rotatably connected to the sliding element and the coupling element rotatably connected to the bolt. As a third alternative, it would be conceivable to connect the sliding element and the coupling element respectively rotatably to the bolt.

In order to prevent damage to the locking device in the event of an overload, for example due to improper pulling on the wing in the direction of the closing direction of the wing, an overload protection can be provided on the locking device, which is designed to ensure positive engagement between the coupling section and the guide element in the latching position to resolve, provided that an overload along the extension direction of the guide rail between the coupling portion and the guide member acts.

The overload protection can be achieved in a simple manner in that the coupling portion and / or a detent position forming portion of the guide element have an inclined surface which rests in the detent position on the portion of the guide member or the coupling portion, and that the coupling element and / or the Section of the guide element are adapted to perform at a acting between the coupling portion and the guide element overload against a restoring force, in particular a spring, a deflection movement perpendicular to the plane of the guide rail.

In order to be able to perform a movement perpendicular to the plane of the guide rail in the event of an overload, the coupling section can be pivotable perpendicular to the plane of the guide rail. For example, the coupling portion is connected via a trained as an arm coupling element with the sliding element or the locking element, which can be pivoted or deformed so that the coupling portion can be solved by the guide element, in particular from the guide slot out. In order to reliably ensure that the coupling section and guide element slide against one another, the said inclined surface is provided on the coupling section and / or the guide element.

Thus, after triggering the overload protection, the locking device can be used directly again, i. without having to reset the overload protection manually, a spring may be provided and arranged so that the movement of the coupling element and / or the guide element takes place against a spring force of the spring when the overload protection is triggered.

• - eine erste Ablenkfläche, die das Kopplungselement bei Bewegung des Schiebeelements in Öffnungsrichtung in einer Richtung quer zur Verschieberichtung des Verschiebeelements ablenkt,
• - eine zweite darauffolgende Ablenkfläche, die das Kopplungselement bei Weiterbewegung des Schiebeelements in Öffnungsrichtung in entgegengesetzter Richtung quer zur Verschieberichtung des Verschiebeelements bis zu einem ersten vorgegebenen Punkt wieder zurücklenkt,
• - eine in Öffnungsrichtung des Schiebeelements weisende konkave Anlagefläche, in deren Mittelbereich die Rastposition definiert ist und die einerseits bis gegenüber dem ersten vorgegebenen Punkt und andererseits bis gegenüber einer dritten Ablenkfläche reicht, die das Kopplungselement bei Bewegung des Schiebeelements in Öffnungsrichtung weiter in derselben Richtung ablenkt wie die zweite Ablenkfläche bis zu einem zweiten vorgegebenen Punkt, der in Querrichtung seitlich der konkaven Anlagefläche liegt, sowie
• - eine vierte Ablenkfläche, die das Kopplungselement bei einer Bewegung des Schiebeelements in Schließrichtung wieder in der ersten Ablenkrichtung bis zu einer Ausgangsposition in Querrichtung betrachtet zurück ablenkt.

According to one embodiment, the guide element has the following elements:

• a first deflection surface, which deflects the coupling element in the direction of opening in the direction of movement of the sliding element in a direction transverse to the displacement direction of the displacement element,
• a second subsequent deflecting surface, which deflects the coupling element as the sliding element continues to move in the opening direction in the opposite direction transversely to the displacement direction of the displacement element up to a first predetermined point,
• - A pointing in the opening direction of the sliding element concave bearing surface, in whose Center region, the latching position is defined and on the one hand extends beyond the first predetermined point and on the other hand to a third deflection, the further deflects the coupling element in the opening direction in the same direction as the second sliding element to a second predetermined point, the Transverse direction is the side of the concave contact surface, as well
• - A fourth deflection, which deflects the coupling element in a movement of the sliding member in the closing direction back in the first deflection direction to a starting position in the transverse direction viewed back.

Such a guide element with deflecting surfaces has the advantage that the guidance of the coupling element and of the coupling section is reliable. In general, however, other types of leadership, for example by means of multiple magnets possible.

In the case of a guide element with an outlet opening before and after the latching position, the guide element can have a fifth deflecting surface which is provided in the region of the outlet opening present in front of the latching position and deflects the coupling element further in the same direction as the second deflecting surface up to when the sliding element moves in the opening direction a third predetermined point having the same position in the transverse direction as the second predetermined point. Several such guide elements can be arranged along the guide rail in order to be able to determine the door leaf in various latching positions and to make it as easy as possible to open the door leaf over a latching position.

In the 1A and 1B is the structure of a locking device according to the invention 10 shown. The locking device 10 is suitable for the wing of one of the locking device 10 associated door, in particular a revolving door or a sliding door, or one of the locking device 10 associated window to keep in a predetermined opening position. For this purpose, for example, on the door frame or window frame a guide rail 12 appropriate. In this guide rail 12 is a sliding element 14 along the guide rail 12 slidably mounted. In the guide rail 12 is also a one as a backdrop guide 24 trained guide element exhibiting locking element 16 arranged, which is immovable and stationary in the guide rail 12 is included. On the sliding element 14 , which may also be referred to as sliding block in the present embodiment, is a coupling element 18 appropriate. The coupling element 18 is formed in the form of a pivot arm and about an axis A a bolt 20 parallel to the plane of the guide rail 12 pivotable. At the of the sliding element 14 remote end of the coupling element 18 is a coupling section 22 appropriate or formed, which in the slotted guide of the locking element 16 can intervene. In other words, the coupling section is located 22 at a height which corresponds to the height of the slotted guide of the locking element 16 at least in certain areas ( 1B) , In contrast, there is the sliding element 14 at a height which coincides with the height of the locking element 16 does not match, so the sliding element 14 the locking element 16 can drive over.

Various variants of the sliding element 14 be in terms of the 3A to 3D and different variants of the slotted guide in relation to the 4A to 4D described in more detail.

The 2A to 2F describe the functioning of the in terms of the 1A and 1B described locking device 10 , In a starting position ( 2A) , which is present for example when the door is closed, is the sliding element 14 in one of the locking element 16 distant area in the 2A to 2F not shown guide rail 12 , The coupling section 22 of the coupling element 18 is not yet on a through the slide guide 24 of the locking element 16 formed guideway 26 , Will the sliding element 14 by opening a door, ie by rotating open a rotary wing or moving a sliding sash, in the direction of the gate guide 24 trained locking element 16 proceed, penetrates the coupling section 22 of the coupling element 18 through an entrance opening 28 in through the slide guide 24 limited guideway 26 and is from the slide guide 24 along the guideway 26 directed. In 2 B pushes the coupling section 22 to a first deflection surface 30 that the coupling section 22 when opening the door relative to the direction of displacement of the sliding element 14 to the left (upwards in the figures). The guideway 26 describes after the left turn a right turn, so that the coupling section 22 by means of a second deflection surface 32 back to the right (in the figures down) is pressed until the coupling section 22 at a first predetermined point 33 has arrived.

In 2C the state is shown in which the coupling section 22 at the first predetermined point 33 has arrived. The door is now open so far that it is in a locked position 34 can be brought. By releasing the door, when the coupling section 22 at the first predetermined point 33 a door closer can be the sliding element 14 in the closing direction, ie in the direction in which the sliding element 14 when closing the door leaf moves (in the figures to the left), pull back. As in 2D can be seen, this is the coupling section 22 against a concave bearing surface 35 moved, in the central region of the detent position 34 is defined and on the one hand to the first predetermined point 33 and, on the other hand, to a third deflection surface 36 enough. In 2D becomes the sliding element 14 over the coupling element 18 on the locking element 16 in the rest position 34 , which may also be referred to as a locking position held by the coupling section 22 at the concave contact surface 35 positively rests and is held by her. The coupling element 18 and the concave contact surface 35 form a metastable system, so to speak, which can be disturbed by pressing against the door leaf in an opening direction of the wing. This is in 2E shown. By pressing against the door in the opening direction of the wing, the sliding element 14 in the opening direction along the guide rail (in the figures to the right), so that the coupling portion 22 with the third deflection surface 36 comes in contact and from this to the right outside (in the figures down) is pressed. At the end of the third deflection area 36 is through the guide element 24 a second predetermined point 40 Are defined. Is the coupling section 22 at this second predetermined point 40 , is the locking device 10 decoupled again. The locking device 10 So automatically decouples, as soon as you get the door from the rest position 34 adjusted a certain way in the opening direction of the wing. If you now let go of the door, the door closer pulls the sliding element 14 along the guideway 26 at the rest position 34 defining concave bearing surface 35 past. In closing movement direction of the coupling section 22 in front of the entrance opening 28 is a fourth deflection surface 42 ( 2F) on the slide tour 24 provided, which is the coupling element 22 in closing movement direction of the coupling portion 22 to the right (in the figures above) to the transversely centered entrance opening 28 redirects.

General describes the guideway 26 thus a closed track, which can be traversed in one direction only. In the middle of the guideway 26 is a latching position 34 defining section 44 of the guide element 16 arranged.

In the 3A to 3D are various exemplary embodiments of a sliding element 14 with different coupling elements 18 shown. Corresponding components are provided with corresponding reference numerals. It is understood, however, that the various coupling elements 18 not necessarily on the sliding element 14 must be arranged, but instead also on the locking element 16 can be arranged. In In this case, then the guiding element would be 24 on the sliding element 14 arranged.

In 3A is designed as a sliding block sliding element 14a shown in its geometric center of the axis A a bolt 20a runs. The coupling element 18 is in the form of a swivel arm 18a formed, which about the axis A of the bolt 20a pivotable on the bolt 20a is stored. On the swivel arm 18a is in one of the sliding element 14a remote end portion of a coupling portion 22 in the form of a conical pin 22a appropriate. The swivel arm 18a has a slight S-shaped curvature, which is best in 1B you can see. That of the coupling section 22 remote end of the swivel arm 18a lies on a bottom 46a of the sliding element 14a at. The coupling section 22a stands from a corresponding underside 50a of the swivel arm 18a so that the height range in which the coupling portion 22a is located does not overlap with the height range in which the sliding member 14a lies.

As in 3B can be seen, the bolt protrudes 20a from the coupling element 18a opposite side of the sliding element 14 out. A protruding section formed thereby 54a can be connected to a closer, not shown, a door closer, in particular rotationally fixed.

In 3C is an alternative embodiment of a sliding element 14 shown. Instead of the swing arm according to this embodiment, a disc 18b provided as a coupling element, which about the axis A a bolt 20b rotatable with a sliding element 14b connected is. At the of the sliding element 14b turned away side 50b of the rotatable disc 18b is a perpendicular to the plane of the guide rail 12 protruding conical coupling section 22b formed.

In 3D is another alternative to the design of a sliding element 14c shown. In this embodiment, the coupling element is by a carriage 18c formed, which is perpendicular to the direction of displacement of the sliding element 14c and parallel to the plane of the guide rail 12 is movable. The sled 18c has a coupling section 22c on which is with the sled 18c emotional. So the sled 18c perpendicular to the direction of displacement of the sliding element 14c and parallel to the plane of the guide rail 12 in the sliding element 14c is movable, is in the sliding element 14c a transverse to the direction of the sliding element 14c extending guide groove 56c formed. The guide groove 56c is along the direction of displacement of the sliding element 14c in the opening direction in front of a bolt 20c arranged.

Furthermore, the show 4A to 4D various guide elements designed as slide guides 24a to 24d ,

In 4A is a guide element 24a shown according to a first embodiment. The guide element 24a forms a non-traversable link guide. The link guide describes a guideway 26a , whose beginning and end are at the entrance opening 28a is defined. In this embodiment, the slotted guide 24a on the entrance opening 28a closed on the opposite side. At the first predetermined point 33a and the second predetermined point 40a is in each case an end stop 58a . 60a provided, which the coupling portion 22 prevents further movement in the opening direction (in the figures to the right) to complete. This allows the coupling section 22 only a short distance 62a over the predetermined opening position and thus the locking position 34a go out.

In 4B which is a guide element 24b according to a second embodiment, the guideway is 26b at the first predetermined point 33b designed open, so that a movement of the coupling portion 22 in the opening direction by the guide element 24b is not limited. There is an exit opening 64b , which in the course of the guideway 26b before the rest position 34b is arranged. In other words, the coupling section 22 in the course of the guideway 26b at the first predetermined point 33b an alternative guideway 67b which do not follow the rest position 34b leads, but to the exit opening 64b , At the second predetermined point 40b is on the other hand a stop 60b provided so that the coupling section 22 at this point 40b is prevented from making a movement in the opening direction (in the figures to the right).

In the in 4C embodiment shown is the guideway 26c at the second predetermined point 40c designed open, so that a movement of the coupling portion 22 at the second predetermined point 40c not in the opening direction by the guide element 24c is limited. The guide element 24c defines an exit port 64c , which in the course of the guideway 26c after the rest position 34c is arranged. The coupling section 22 must therefore be in the course of the guideway 26c in the rest position 34c before going through the exit opening 64c can be performed.

In 4D is a guide element 24d to see whose guideway 26d at the first given point 33d and at the second predetermined point 40d is designed open. This will cause a movement of the coupling section 22 in the opening direction neither at the first predetermined point 33d , still at the second predetermined point 40d through the guide element 24d limited. There are two different alternative guideways 67d . 68d to the exit opening 64d , where the first alternative guideway 67d at the first predetermined point 33d and the second alternative guideway 68d at the second predetermined point 40d starts and both at a third predetermined point 70d to merge. This is a fifth deflection 72d provided, which extends along the first alternative guideway 67d moving coupling section 22 in the transverse direction, ie transverse to the opening direction, as far as deflects to the coupling section 22 at the third predetermined point 70d in the second alternative guideway 68d located. The second predetermined point 40d and the third predetermined point 70d have the same position in the transverse direction, ie their distance from the central axis of the guide element extending in the direction of displacement 24d is the same size.

There may be several of the open designed guide elements 24b . 24c or 24d along a guide rail 12 be arranged so that the door in several locking positions 34b . 34c . 34d can be determined. For easy recording of the coupling section 22 are the entrance opening in the embodiments shown 28 and the exit port 64 designed so that they are each in the direction of the center of the guide element 24 rejuvenate.

So with an overload 74 at the locking device 10 This is not damaged, may be on the locking device 10 , especially in the 5A to 5D shown an overload protection 76 be provided. This is designed to form a positive connection between the coupling section 22 and the guide element 24 in the rest position 34 to dissolve when between the coupling section 22 and the guide element 24 acting force exceeds a threshold. The 5A and 5B show a first alternative, such as such overload protection 76a can be realized. The coupling section 22a is conical and therefore has an inclined surface 66a on. This bevel 66a is in the rest position 34 with an upper edge 78a the concave contact surface 35a in contact. Has an overload 74 on the sliding element 14 , slides the conical coupling section 22a at the top edge 78a along from the guide element 24 out ( 5B) , While the conical coupling section 22a from the guide element 24 slides out, formed as a pivot arm coupling element deforms 18a elastic. The swivel arm 18a thus acts as a spring 80a , which the coupling section 22a with regular use in the guideway 26 stops and overloads 74 releases for an evasive movement.

The 5C and 5D illustrate a second embodiment of an overload protection 76b , Here have the rest position 34 forming section 44b and the coupling section 22b one inclined surface each 82b . 66b on. The inclined surfaces 66b . 82b lie flat against each other at regular load, without sliding off each other when the coupling section 22b in the rest position 34 located. However, it has an overload 74 between the coupling section 22b and the rest position 34 forming section 44b , gives way to the detent position 34 forming section 44b against a spring force of a spring 80b perpendicular to the plane of the guide rail 12 out. For this purpose is the detent position 34 forming section 44b in the direction perpendicular to the plane of the guide rail 12 slidable in the remaining guide element 24b stored. The inclined surface 66b of the coupling section 22b slides on the inclined surface 82b along until the rest position 34 forming section 44b so far in the rest of the guide element 24b has penetrated that of the detent position 34 forming section 44b the coupling section 22b releases. Due to the restoring force of the spring 80b becomes the detent position 34 forming portion 44 b pushed back to the starting position once the coupling portion 22b passed through section 44b.

Both embodiments of the overload protection 76a . 76b have the advantage that the evasive movement automatically by the restoring force of the spring 80a . 80b is undone so that no repair or other service activity occurs after the overload protection has been triggered.
