The present invention relates to a sliding wing system according to the preamble of claim 1 and to a closing edge construction therefor.
Sliding wing systems, in particular sliding door systems, are widely used, preferably at locations where building openings are frequently passed through by people. A sliding wing system is capable of rapidly and reliably operating a large building opening through which one or more people can pass at the same time. It is a fundamental requirement that said sliding wing systems also prevent unauthorized entry, i.e., for example, are lockable overnight. The main closing edge of said systems constitutes a weak point in the closing system for safety against intrusion.
WO 2010 034 081 A1 discloses a lock with an engagement element, which is mounted movably along the main closing edge, on a sliding wing. When the door is closed, said engagement element is movable from a release position into a locking position, wherein said engagement element can be brought into engagement with a counterpart, which projects into the movement of the engagement element, on the other sliding wing and can then be fixed, and therefore the sliding door is closed. However, such a construction is disadvantageous since relatively large openings and/or elements protruding in the closing direction have to be provided in the closing edges of the sliding doors for engagement of engagement element and counterpart. In addition, a complicated construction reliably providing the linear movement of the engagement element over several centimeters has to be provided for the actuation of the closing mechanism.
Sealing elements for sealing the main closing edge in sliding door systems are known, for example, from DE 102 12 09 B4, DE 10 2006 062 332 A1 and EP 1 431 501 B1. Said sealing elements seal the closing edge in particular in respect of gas exchange, but do not increase the security of the door system against unauthorized entry.
U.S. Pat. No. 3,774,342 discloses a sliding door in which a groove/ridge-like construction engages in each other on a vertical closing edge and a closing mechanism is provided in this region.
It is therefore an object of the present invention to provide a sliding wing system, in particular a sliding door system or sliding window system or a closing edge construction, which provides increased mechanical stability for better protection against intrusion.
This object and further objects are achieved by a sliding wing system, in particular an automatic sliding door system, comprising at least one sliding wing, wherein the sliding wing is displaceable in a floor guide device along a closing movement so as to close a building opening in a pass-through direction and provides a first vertical closing edge in a substantially horizontal closing direction, and the sliding wing system provides a second vertical closing edge, wherein the first and the second vertical closing edge can be brought into closing contact with each other, and wherein the sliding wing provides a horizontal closing edge which, together with the floor guide device, forms a horizontal secondary closing edge extending along the closing direction, in that at least one dimensionally stable outer flank which extends substantially in the vertical direction, protrudes freely in the closing direction and is composed of metal or plastic or a combination thereof, which is attached on the corresponding vertical closing edges in a manner offset toward an outer side of the building opening, is provided at least in sections on at least one of said vertical closing edges, in that a dimensionally stable ridge which corresponds to said outer flank, extends substantially in the vertical direction and protrudes in the closing direction and is composed of metal or plastic or a combination thereof is arranged on the other vertical closing edge, in each case opposite said outer flank, wherein said ridge runs with respect to the outer flank in a manner offset laterally toward an inner side of the building opening and, by means of the closing movement, can be brought into engagement (by a form-fitting connection in the pass-through direction) with an inner side of the flank, which inner side is directed toward the inner side of the building opening, and in that a closing device which is arranged on said vertical closing edges and has at least one locking point for fixing the sliding wing when the first and second vertical closing edges are in closing contact with each other is provided, wherein said locking point is provided on the ridge side, and therefore the outer flank covers the locking point toward the outer side of the building opening.
The outer flank together with the vertical closing edge, to which said flank is attached, forms a first step or a first offset, wherein the ridge together with the other vertical closing edge forms a second step or a second offset. The first step and the second step are of mirror-inverted design here such that they can intermesh in the closing direction. The first and the second step can also be of multi-stepped configuration. The outer flank here engages over the ridge at least partially, preferably substantially entirely, and therefore the ridge is covered toward the outer side of the building opening by the outer flank. A free end of the ridge is therefore not accessible from the outer side when the vertical closing edges are in closing contact.
A development of the sliding wing system is characterized in that a further, inner flank which runs substantially parallel to the outer flank and is attached in a manner offset at a distance in the pass-through direction from the outer flank toward the inner side of the building opening is provided on the vertical closing edge providing the outer flank. This inner flank also protrudes toward the ridge, wherein the inner flank is substantially mirror-symmetrical to the outer flank with respect to a mirror plane, wherein said mirror plane is a vertical plane through the wing center and parallel to the building opening.
A substantially vertically running groove is formed between the outer flank and the inner flank, said groove being open in the closing direction and being bounded in a direction parallel to the pass-through direction by the outer and the inner flank. The flanks preferably protrude here over the vertical closing edge substantially by the same amount in the closing direction. The groove formed here and said ridge are configured here in such a manner that they can be brought into mutual engagement by the closing movement. It is preferred that said engagement, taken together in sections, extends over at least half of the longitudinal extent of the vertical closing edges, preferably over the entire longitudinal extent of the vertical closing edges. Furthermore, it is preferred that said ridge extends in the pass-through direction substantially over the clear width of the groove and in the vertical direction substantially over a length of the groove. In an advantageous manner, upon engagement in the groove, the ridge engages in the groove substantially as far as to a depth of the groove. Thus, in particular, the outer flank of the ridge is supported and can readily withstand pressure perpendicularly on the flank (from the outside).
It is preferred that the flank(s) protrudes or protrude over the vertical closing edge in the closing direction freely by 10 millimeters to 30 millimeters and has or have here a material thickness in the pass-through direction, said material thickness preferably tapering toward a free end of the flank(s) and in each case being at least 2 millimeters to 10 millimeters, preferably more than 3 millimeters, in particular 4 millimeters or more. The ridge can then be, for example, 20 to 90 millimeters in width at its free end in the pass-through direction.
The flank here should therefore be understood as meaning a ridge-like projection which covers the ridge toward the inner side (inner flank) or outer side (outer flank) of the building opening. The vertical closing edges are brought together in the closing direction on the ridge and in the depth behind the flank on that side of the flank which faces the ridge (i.e. in the vicinity of the extension of the flank on the vertical closing edge, and away from the free end of said flank) and are lockable there to protect the flank against access from the outer side.
The tongue and groove system therefore solidly prevents the accessibility by means of a burglary tool to the locking points, for example to pivoting bolts.
It is furthermore preferred that the ridge is attached to the corresponding vertical closing edge in a manner offset toward the inner side of the building opening, and therefore, when the vertical closing edges are in closing contact, the outer flank which is provided so as to be able to cover the ridge toward the outer side of the building opening engages over the ridge in the closing direction to such an extent toward the vertical closing edge providing the ridge that a vertically running gap between the free end of the outer flank and the vertical closing edge providing the ridge has a clear width in the closing direction of less than 2 millimeters, in particular of less than essentially 1 millimeter. Preferably, in a region about said vertical gap running along the main closing edge formed by the vertical closing edges, a substantially aligned surface is formed toward the outer side of the building opening. This makes it difficult to insert a lever tool (or impact tool) for the purpose of prying open the flank and increases the security of the system against intrusion. Such an engagement of the flank over the ridge is intended to be provided in particular from the attack side (the outer side of the building opening), but may also be implemented on the inner side of the system.
The flanks are preferably flanks which are spaced apart with respect to each other in the pass-through direction by preferably at least 10 millimeters or more, in particular by 20 to 90 millimeters, and which preferably run substantially continuously along the vertical closing edge. Said flanks here are preferably attached to end regions, which lie opposite each other in the pass-through direction, of the corresponding vertical closing edge, i.e. in the vicinity of the vertical edges of the sliding wing.
The groove formed by the inner and outer flanks here preferably has a depth in a direction parallel to the closing direction of at least 10 millimeters to 30 millimeters or more, wherein a clear width in the pass-through direction is at least 10 millimeters or more, in particular 20 to 90 millimeters.
The abovementioned and further objects are also achieved by a sliding wing system, comprising at least one sliding wing, wherein the sliding wing is displaceable in a floor guide device along a closing movement so as to close a building opening in a pass-through direction and provides a first vertical closing edge in a substantially horizontal closing direction, and the sliding wing system provides a second vertical closing edge, wherein the first and the second vertical closing edge can be brought into closing contact with each other, and wherein the sliding wing provides a horizontal closing edge which, together with the floor guide device, forms a horizontal secondary closing edge extending along the closing direction, in that at least one dimensionally stable groove which substantially extends in the vertical direction, is open in the closing direction, and is composed of metal or plastic or a combination thereof is arranged at least in sections an at least one of said vertical closing edges, and a dimensionally stable ridge which corresponds with said groove, extends substantially in the vertical direction and protrudes in the closing direction and is composed of metal or plastic or a combination thereof is arranged on the other vertical closing edge, in each case opposite said groove, wherein said groove and said ridge can be brought into engagement in a form-fitting manner by the closing movement, wherein said engagement, taken together in sections, extends over at least half of the longitudinal extent of the vertical closing edges, and in that, furthermore, a closing device which is arranged on said vertical closing edges and is intended for fixing the sliding wing when the first and second vertical closing edges are in closing contact with each other is provided.
The expression “taken together in sections” means that all of the vertical sections of the vertical closing edge that provide such an engagement upon mutual contact, when totaled in their length over the vertical extent, produce at least half of the length of the longitudinal extent of a vertical closing edge. In other words, the vertical closing edge intermesh over at least half of their vertical extent via a tongue and groove connection.
The groove is configured as a channel-shaped depression, with a depth of preferably at least essentially 10 millimeters, in particular from essentially 11.5 millimeters up to 30 millimeters. The ridge, a projection running along the main closing edge, is functionally configured as a tongue and is suitable for forming a tongue and groove connection with the groove. It is expedient here to allow the ridge to grip as far as to the depth of the groove (i.e. to the rear boundary thereof) so that sufficient mechanical stability is produced in the closing position. It is therefore clear that it is preferable if the ridge projects in the direction of the groove to approximately the same amount as the depth of the groove. Said corresponding elements (groove and elevation) are therefore preferably substantially formed as geometrical counterparts.
The expression “dimensionally stable” means that the intermeshing elements—groove and ridge—remain in engagement in a dimensionally stable manner even under the action of a force, in particular from the pass-through direction (and are also correspondingly inherently stable), and counter said action of force. Typical forces would be, for example, if action is taken against the door; such a force can be, for example, 100N to 6000N or more. In order to withstand such forces, the ridge and the groove are formed so as to correspond in dimensions (see below) such that forces which are directed against a weak point of the closing system, namely against groove and/or ridge, for example in the event of an intrusion attempt, can be absorbed. In addition, sensitive elements of the closing device are intended to be concealed in said groove and/or the ridge and the adjacent profiles and to be accommodated in a manner difficult to access. If the system is in the closed position, flanks which form the groove surround the ridge laterally over at least 8 to 15 millimeters and preferably come into contact with the side surfaces of the ridge in the pass-through direction. The flanks are preferably laterally supported by the ridge if the inherent stability of said flanks does not suffice in the event of an action of force from a direction at an angle to the closing direction. Access into the groove is therefore effectively blocked and the closing device is accessible at least in this region only by the flanks being broken open. Therefore, the flanks which act in a concealing manner are intended to be formed so as also to be sufficiently thick and made from a strong material that unauthorized entry (in particular to the locking mechanism) is effectively countered.
In order to prevent the sliding wings from being slid open (along the closing movement), the stable closing device is provided, said closing device securing the engagement of the ridge in the groove and preferably being at least partially surrounded by groove and/or ridge and therefore likewise being protected from unauthorized access.
It is preferred if the groove has a depth of at least 10 millimeters or more in a direction parallel to the closing direction and has a clear width in the pass-through direction of at least 10 millimeters or more. The groove can be formed here by flanks which are attached to the corresponding vertical closing edge, preferably protrude in the closing direction by 10 millimeters to 30 millimeters and are spaced apart with respect to each other in the pass-through direction by preferably at least 10 millimeters or more, in particular by essentially 25 millimeters, and preferably run substantially continuously along the vertical closing edge. Said flanks can preferably be attached to end regions, which lie opposite each other in the pass-through direction, of the corresponding vertical closing edge, preferably in a manner aligned from the outside with the sliding wing, wherein the flanks are in each case free-standing in the closing direction and the respective thickness or material thickness of said flanks is 1 millimeter to 10 millimeters, preferably more than 3 millimeters, in particular 4 millimeters or more, in the pass-through direction and, preferably, said material thickness tapers by 10% to 50% in the closing direction (i.e. toward the free end of the flank). If the flanks are thus considered in a cross-sectional view (sectional plane formed by pass-through direction and closing direction), the flanks taper in the closing direction toward their respective free end. It is particularly preferred if the vertical profiles which are in closing contact form an aligned surface on the inner side and the outer side of the wing (i.e. perpendicularly to the pass-through direction). This then means that the flanks preferably taper on the groove side (i.e., that is to say internally; in other words: on the ridge side when the system is closed) in material thickness in the pass-through direction. The groove, i.e. the corresponding recess, is therefore then of substantially trapezoidal cross-sectional design at least in sections.
The locking of the sliding wing/sliding wings then takes place in the depth of the groove, and therefore the locking mechanism is protected by the mentioned flanks of the groove.
It is furthermore advantageous in this connection if the flanks of the groove fit snuggly against the ridge in such a manner that the vertical gap on the main closing edge is reduced to a minimum of approximately 1 millimeter or less. This prevents or makes difficult the fitting of lever tools, for example a crowbar, for the purpose of prying open the flanks of the groove. The gap mentioned is intended to be minimal in particular on the sliding wing side toward the outer side of the building, the attack side.
In order to ensure this, it is preferred not to allow the sides of the ridge, in a cross-sectional view, to run as far as the vertically running edges of the corresponding vertical profile. An offset is therefore produced in the pass-through direction, in which the flanks of the groove can engage. In addition, this makes it possible for the flanks of the groove to continue to be sufficiently thick in the pass-through direction (3 to 4 millimeters or more) at their free ends despite a possible tapering so that said flanks cannot be easily bent upward or broken open.
The ridge can be attached to the other vertical closing edge lying opposite said groove, wherein said ridge extends substantially over the clear width of the groove in the pass-through direction and substantially over a length of the groove in the vertical direction and, upon engagement in the groove, engages substantially as far as to a depth of the groove, i.e. the ridge projects, for example, by 8 millimeters or more, depending on the design of the groove.
It is preferred that the closing device provides at least one engagement recess, which is continuously open in the closing direction toward the outside, on one of said vertical closing edges, preferably in the ridge or in the depth of the groove. The closing device here can have at least one bolt which is attached to the other vertical closing edge and is preferably arranged in the depth of the groove or in the ridge and which, when the vertical closing edges bear against each other in a closing manner for locking the sliding wing, is rotatable, pivotable and/or displaceable into said engagement recess for the form-fitting engagement with respect to a direction parallel to the closing direction, wherein said engagement recess and the corresponding bolt form a locking point.
It is preferred that the vertical closing edges provide at least two vertically spaced-apart locking points which form a pair and which are each protected in the locked state by the flank from access on the flank side. The force produced by the use of the burglary tool therefore always acts on at least two locking points because of the construction. The load per individual locking point is therefore theoretically halved, but in any case reduced.
A distance between said two locking points is preferably 50 millimeters to 250 millimeters or less, in particular essentially 150 millimeters, wherein, preferably, two or more such pairs of locking points are arranged distributed over the vertical closing edges. It is particularly preferred to provide a pair of locking points above the center of the main closing edge and a further such pair below said center.
The closing device can provide, for example, at least one closing strip which is attached in the ridge and preferably runs vertically and which at least partially, preferably completely, surrounds the engagement recess. The closing device can provide at least one pivoting bolt case, which is attached in the depth of the groove, with a pivoting bolt which is mounted along a pivoting movement and, when the vertical closing edges bear against each other, so as to be pivotable from the pivoting bolt case into the respective engagement recess into a locking position, wherein the pivoting bolt preferably engages behind the closing strip in the locking position. The form-fitting connection is therefore provided in a direction parallel to the closing direction.
In order to optimize the tightness of the pivoting bolt, an entry slope can be provided in each case on the closing strip. The pivoting bolt then interlocks in the closing strip, and therefore the system is locked. In this connection, for example, known pivoting bolt closing parts can be used in an alternating or identical orientation. The pivoting bolt closure is advantageously provided with a means of securing against counterpressure.
The pivoting bolt is preferably formed from steel or from another material known to a person skilled in the art, wherein the bolt has a material thickness of at least 3 to 8 millimeters or more. Material choice and dimensioning depend on each other in a manner known to a person skilled in the art. Depending on the intended purpose, hardened or non-hardened bolts can be used. Additional centering pins protruding in the closing direction can be provided on the groove and/or ridge and a corresponding recess can be provided on the ridge and/or groove opposite each pin in order to guide the engagement between groove and ridge and to strengthen the system in the closing position.
In a development of the invention, a form-fitting connection is intended to be provided on the secondary closing edge in order further to improve the stability of the system (especially in the closed position) and the operability of said system. For this purpose, at least one floor bolt with an engagement element can be provided on the horizontal secondary closing edge of the at least one displaceable sliding wing, wherein the engagement element preferably protrudes downward by 5 millimeters to 50 millimeters from the horizontal secondary closing edge and preferably extends over 50 millimeters to 200 millimeters along the closing direction. Said floor bolt is preferably also manufactured from steel (preferably hardened, but can also be non-hardened material). Furthermore, the floor guide device can provide, along the closing movement, a floor guide profile with a guide chamber which is open upward, is bounded in the pass-through direction by a guide chamber wall and corresponds with the floor bolt, wherein, preferably, a floor connecting profile which is embedded in the floor (for example set in concrete) and is intended for receiving the floor guide profile is provided. Floor connecting profile and floor guide profile can be made from metal and fixed in relation to each other (for example by screwing). The engagement element of the floor bolt is movable displaceably along the closing movement in a manner projecting substantially over its protrusion height (in the vertical direction) in the guide chamber and guiding the displaceable sliding wing, wherein the floor bolt preferably makes contact with the guide chamber wall via a sliding element (for example made from plastic) in order to prevent a metal/metal rubbing contact. Said sliding element can also act in a noise-reducing manner and/or can improve the frictional properties of the system.
The engagement element is therefore guided along the closing movement (which includes both directions) in the guide chamber, in a manner identical to a sliding block in a groove, and therefore a form-fitting connection is provided in the pass-through direction, which increases the mechanical stability. The sliding wing system can in particular comprise at least one first sliding wing and one second, opposed sliding wing for closing the building opening, which sliding wings are displaceable in the floor guide device along the closing movement and parallel to the closing direction in a manner releasing or closing the building opening. This travel path therefore determines the closing movement. In this connection, the first sliding wing in the closing direction (with respect to the first wing) provides the first vertical closing edge and the second sliding wing in the closing direction (with respect to the second wing) provides the second vertical closing edge.
It is preferred that the first vertical closing edge is provided by a first vertical profile and the second vertical closing edge is provided by a second vertical profile, wherein said vertical profiles are preferably formed from metal or plastic or a combination of said materials. The vertical profiles are also intended to be provided to be correspondingly dimensionally stable and therefore unbreakable.
The vertical profiles are preferably formed identically in the rear region and are differentiated by the provision of the groove or the ridge. The vertical profiles preferably extend by 40 millimeters to 200 millimeters, preferably essentially 100 millimeters, in the closing direction and by 20 millimeters to 100 millimeters, preferably 35 millimeters, in the pass-through direction and preferably substantially over an entire height of the the building opening (for example 2.2 to 3.5 meters). One of the first and second vertical profiles provides the at least one groove, preferably extending along the entire vertical closing edge, and the other vertical profile provides the ridge corresponding with said groove, preferably extending substantially along the whole of the groove. The groove/the ridge can therefore be provided on the first or second vertical closing edge or in sections on the first vertical closing edge and in a different section on the second vertical closing edge. It is also possible in principle for two grooves or two ridges or for one groove and one ridge to be provided parallel to a vertical closing edge, wherein the vertical closing edge arranged opposite is then configured in a complementary manner so that the desired form-fitting engagement is possible. The groove can be configured, as seen in a cross section from the vertical direction (horizontal section), so as to be substantially rectangular or trapezoidal at least in sections or preferably over the entire depth and so as to widen in the closing direction. Said widening of the groove in the closing direction advantageously acts on the ridge in a receiving and centering manner, also as defined by the centering pins.
It is preferred that the first and the second vertical profile intermesh along the first and second vertical closing edges and parallel to the closing direction in a manner forming a substantially aligned surface. When in contact with each other (in the closed position), the first and second vertical profiles therefore form an aligned surface. This permits a slender construction and acts in an esthetically advantageous manner.
The floor bolts mentioned are preferably attached to the two lower corners of the sliding wing such that the sliding wing is guided and secured at the rear and front. The floor bolts have an L shape. By introduction of the L-shaped floor bolts into the frame of the sliding wing, the corner regions are additionally reinforced, which further increases the security against intrusion.
It is therefore preferred that the at least one displaceable sliding wing provides a vertical terminating profile on its end section opposite the vertical closing edge, wherein the horizontal closing edge is in each case formed by lower ends of the vertical profile and of the vertical terminating profile and preferably by a horizontal profile connecting said lower ends of the vertical profile. The vertical profile, the vertical terminating profile and the horizontal profile then form the frame of the sliding wing (at least laterally and at the bottom). In this connection, one of said floor bolts can be provided in each case on the horizontal closing edge, on the end side in a direction parallel to the closing direction (i.e. in the lower corner regions).
It is furthermore preferred that the floor bolts are each substantially L-shaped and each have a first limb preferably protruding by 40 millimeters to 200 millimeters horizontally over the engagement element and in each case a second limb preferably protruding by 40 millimeters to 150 millimeters vertically upward over the engagement element. The engagement element therefore forms the L shape with said limbs. In this context, the floor bolts can in each case be fastened by the first limb to the horizontal closing edge, wherein the respective vertical profile and the vertical terminating profile of a sliding wing at their lower ends in each case provide vertical chambers which are open downward and run in the vertical direction and into which the respective second limb of the floor bolts can in each case preferably be completely pushed and can be fixed there.
A preferred development is characterized in that a lock plate which extends in the vertical direction, and is fixed in a form-fitting manner in the vertical profile at least with respect to a direction parallel to the closing direction, limits the groove in depth, in that a vertical chamber extending rearward into the sliding wing is provided on an inner side of said lock plate, said inner side facing away from the vertical closing edge, and in that the at least one pivoting bolt case with a pivoting bolt is fastened so as to project from said inner side of the lock plate into a depth of the vertical chamber counter to the closing direction. In this connection, the pivoting bolt is pivotable in a pivoting movement out of the pivoting bolt case through a recess in the lock plate into the groove and, when the vertical closing edges are in closing contact, into the engagement recess and is preferably fixable in said pivoted-out state.
A lock plate with a U-shaped cross section is preferred. The free ends of the U lock plate preferably protrude here to the rear toward the vertical chamber, wherein the free ends are preferably received in the vertical profile in a form-fitting manner with respect to the pass-through direction via corresponding slots in the vertical profile. The U lock plate therefore engages on both sides in the vertical profile over the depth of the groove (and therefore the groove is limited in depth by the lock plate) and therefore stabilizes the flanks which are provided by the vertical profile and bound the groove in the pass-through direction. The flanks are, as it were, held together, which additionally secures the groove/ridge engagement and counters a forcible breaking open of the groove from the outside (for example with the aid of a lever tool).
In addition, it is conceivable that the pivoting bolt case is fastened at the rear in the depth of the vertical chamber by means of a further form-fitting connection with respect to a direction parallel to the closing direction, preferably via at least one mushroom-headed pin which is attached to the pivoting bolt case and protrudes rearward into the depth of the vertical chamber and which is fixable in a form-fitting manner in recesses in a holding strip which is attached in a form-fitting manner with respect to the direction parallel to the closing direction in the depth of the vertical chamber.
A driving rod is advantageously provided, by means of which the closing device is actuable (lockable or unlockable) manually or automatically, wherein a central lock is provided for the manual actuation. The driving rod here can be designed so as to engage in the pivoting bolt case in order there, in the pivoting case, to guide the pivoting bolt located therein over a pivoting movement, wherein the pivoting bolt can be brought from a starting position (in which it is preferably completely retracted into the case) via the pivoting movement into the locking position. The driving rod preferably runs in the lock plate, preferably from the inner side thereof in the vertical profile, as a result of which the driving rod is difficult to access. The linear movement of the driving rod is then converted into the pivoting movement of the pivoting bolts.
In the locking position, the pivoting bolt can protrude through the U lock plate toward the closing strip and can engage through the ridge or into the ridge into recesses of the closing strip and can lock the main closing edge in a form-fitting manner with respect to the closing movement.
Furthermore, it is preferred that at least two pivoting bolt cases are each provided with at least one pivoting bolt. It is advantageous in this connection to provide at least two said pivoting bolts close to each other. Close here means spaced apart vertically from each other by 20 millimeters to 300 millimeters. By means of this directly adjacent arrangement, the forces which act on the lock and therefore in particular also on the pivoting bolts, for example, in the event of an intrusion attempt, are in each case distributed substantially uniformly to the at least two adjacently arranged pivoting bolts and therefore to at least two locking points. This increases the security of the arrangement against intrusion.
In a particularly preferred embodiment, at least two pairs of preferably vertically spaced-apart pivoting bolt cases are provided, wherein a lower pair of pivoting bolt cases is attached below the central lock and/or the motor, and an upper pair of pivoting bolt cases is attached above the central lock and/or the motor. In this connection, the pivoting bolts are provided preferably following different pivoting movements in pairs, wherein the pivoting movements are differentiated in particular in that the pivoting bolt is either pivotable from the bottom upward or from the top downward into the respective engagement recess of the closing strip.
It is preferred here that the pivoting bolts of the upper pair of pivoting bolt cases are both provided so as to be pivotable from the bottom upward or, alternatively, are both provided so as to be pivotable from the top downward, wherein the pivoting bolts of the lower pair of pivoting bolt cases are then both provided so as to be pivotable in an opposed manner to the upper pair of pivoting bolts, namely from the top downward or both are provided so as to be pivotable from the bottom upward. The pivoting bolts of the upper pair of pivoting bolt cases and the pivoting bolts of the lower pair of pivoting bolt cases are therefore pivotable in a substantially opposite direction with respect to the main closing edge (i.e. in an opposed manner). The two pairs of pivoting bolt cases then lock in a form-fitting manner with respect to a direction parallel to the main closing edge, and the locked sliding wing cannot be displaced vertically, and therefore it is not possible to disengage the pivoting bolt hooks which engage behind the closing strip. Such a configuration therefore prevents the hook-like pivoting bolts which engage behind the engagement recess from being simply disengaged.
A sealing profile, for example a central sealing rubber, is preferably attached to the main closing edge, said sealing profile sealing the flanks, which engage around the ridge and form the groove, toward the elevation, and therefore the closure between groove and elevation is sealed.
A closing edge construction for a sliding wing system, as depicted above, can achieve the object of the present invention in that the groove is formed by flanks which are attached to one of the vertical closing edges, preferably provide a vertical profile, preferably protrude by 5 millimeters to 20 millimeters in the closing direction and are spaced apart from one another in the pass-through direction and preferably run substantially continuously along the vertical closing edge, wherein said flanks are preferably attached to end regions of the vertical closing edge, which end regions are opposite each other in the pass-through direction, wherein the flanks are each free-standing in the closing direction and the respective material thickness thereof in the pass-through direction is in each case at least 1 millimeter to 10 millimeters, preferably more than 3 millimeters, in particular of 4 or 5 millimeters or more, and wherein, preferably, said material thickness tapers by 10% to 50% in the closing direction.
In a development, the above-described sliding wing system can comprise an anti-prying-open means which is provided above the at least one sliding wing. At least when a building opening is closed, said anti-prying-open means can limit raising of said sliding wing substantially in the vertical direction and/or pivoting of said sliding wing in the pass-through direction, in particular for the purpose of disengaging a floor bolt, in particular the abovementioned floor bolt, in each case by the anti-prying-open means striking against an element arranged lying opposite the anti-prying-open means, wherein said opposite element in particular comprises parts of a running profile or of a running carriage for moving said sliding wing. It is preferred in this connection that, if the anti-prying-open means strikes upward due to a prying-open attempt and therefore interrupts the lifting movement, the anti-prying-open means (for example a metal plate) makes extensive contact with the opposite element (for example the running profile). Said extensive contact is then preferably such that a displacement of the sliding wing along the closing movement from the closed state into the open state of the building opening is made difficult because of friction or is prevented by a form-fitting connection. For this purpose, the abovementioned extensive contact can take place via rough, but at any rate not smooth, contact surfaces, wherein the friction between the contact surfaces, which are pressed against each other and interrupt the lifting movement, then makes it difficult to displace the sliding wing for the purpose of opening the sliding system. As an alternative or in addition, the elements or surfaces entering into contact can have, for example, a corresponding toothing. Individual ridges of the toothing can then run in the pass-through direction, and therefore the anti-prying-open means and the element lying opposite thereto can be brought into engagement in such a manner that the abovementioned displacement of the raised sliding wing is made impossible.
It is furthermore conceivable that the above-described sliding wings are guided at the top in guide rails via a running carriage, preferably two or more running carriages. Said guide rails are preferably provided here by a running profile which is fixed in a stationary manner, for example, to a wall, but at any rate securely above the sliding wings. The sliding wings then extend into the running profile via the running carriages, wherein the running carriages in each case provide running wheels by means of which the running carriages are movable in the running profile. The running wheels here preferably have concave or convex running surfaces. The running carriages can then be placed by said running wheels, which are preferably arranged in a row, into the correspondingly complementarily shaped guide rail, come into engagement with the rail and are mounted movably together with the sliding door. By means of the abovementioned complementary configuration of wheel and rail, the running carriage is also pivotable over a limited angular range of, for example, 5 to 15 degrees without the construction being damaged due to the transverse forces in effect. However, this pivoting movement may also lead to security problems; for example, due to willful pivoting into a limit region, access from the outside to the inner construction is possible or the sliding wing can even be disengaged.
Means can therefore be provided which close said security gap. A sliding wing system with at least one displaceable sliding wing can thus be provided, wherein a running profile is provided above the sliding wing, wherein the sliding wing engages upward into the running profile over at least one, preferably two running carriages, wherein the running carriage is hooked into the running profile and is movable by means of running wheels on a guide rail provided by the running profile, wherein the running carriage provides at least one, preferably two, anti-prying-open means.
A first anti-prying-open means can be a contact element which protrudes upward from the running carriage and is dimensionally stable, for example a metal plate, wherein said contact element is arranged preferably in a manner offset horizontally from the running wheel with respect to a vertical direction and limit a lifting movement of the running carriage or of the wing upward by coming into contact with a preferably stationary element (which is preferably provided by or on the running profile) which acts as a stop. When the running carriage is pivoted in a direction parallel to the pass-through direction, said first anti-prying-open means or a second anti-prying-open means, which can also be of plate-like design, can serve as a contact element for a further stop in the pivoting direction. The further stop here is preferably again a stationary element which is provided by or on the running profile. Said stops are intended to be provided in particular whenever the sliding wing is in the closed position. Further embodiments are indicated in the dependent claims.
Preferred embodiments of the invention are described below with reference to the drawings which serve merely for explanation and should not be interpreted as being restrictive. In the drawings:
It is therefore noted that, in the present text, unless understood otherwise from the context, the closing direction should be understood as always being related to the respective sliding wing.
The two sliding wings 4, 6 together with their respective lower horizontal closing edges 4b, 6b and a floor guide device 150, 160 in each case form a horizontal secondary closing edge N1, N2. The vertical secondary closing edges 4b, 6b are formed on the vertical edges of the respective sliding wings 4, 6, which edges in each case lie opposite the abovementioned vertical closing edges 4a, 6a. The elements assigned to the first sliding wing 4 (on the right in
The floor guide profile 150 is embedded in a floor connecting profile 160. The floor guide profile 150 is, for its part, embedded in the floor and provides the support surfaces 153 on which support elements 161 of the floor connecting profile 160 rest. The floor guide profile 150 and the floor connecting profile 160 can be fastened here, for example screwed, to each other and in the floor. Furthermore,

In addition, a door filling 67, for example made of glass, of the second sliding wing 6 can be seen on the left in
The vertical profiles 40, 60 are preferably composed of metal or plastic or of a combination of said materials or of other dimensionally stable materials known to a person skilled in the art, and therefore are extremely dimensionally stable and burglary-resistant, and extend from the floor as far as the lower end of the upper light 5. The walls of the vertical profiles 40, 60 have a thickness of 2 to 5 millimeters. In the closing direction S, the vertical profiles 40, 60 have a width of essentially 100 millimeters, wherein said vertical profiles have a material thickness in the pass-through direction D of 25 to 100 millimeters, in particular of 35 millimeters. The horizontal profile 69 and the vertical terminating profile 68 have the same material thickness in the pass-through direction D. The height of the horizontal profile 69 is 50-120 millimeters, and the longitudinal extent thereof in the closing direction S is up to 200 centimeters. The vertical terminating profile 68 likewise extends from the floor as far as the lower end of the upper light 5 and has a width of essentially 100 millimeters in the closing direction S.
The second horizontal closing edge 6b is now explained. The second horizontal closing edge 6b is provided by the lower ends of the vertical profile 60, of the vertical terminating profile 68 and of the horizontal profile 69. A recess 65 is arranged on the second horizontal closing edge 6b (which is in principle formed in a mirror-inverted manner to the horizontal closing edge 4b with respects to the main closing edge H). Furthermore, the floor bolts 11, 13 which engage in the recess 65 and in the vertical profile 60 and the vertical terminating profile 68 (see below and in
With respect to the main closing edge H, the floor bolt in the first vertical profile 40 is formed and attached in a substantially mirror-symmetrical manner to the floor bolt 11 in the second vertical profile 60. The two floor bolts in the vertical profiles 40, 60 are then directed toward each other with respective projections 116. Said projections complete the construction below the main closing edge H in the closing direction S. Furthermore, respective first horizontal limbs 111, 131 and second vertical limbs 112, 132 of the floor bolts 11, 13, which are therefore L-shaped, are illustrated in
The construction of the floor bolts 11, 13 is now described more precisely with reference to
A first floor bolt 11 is illustrated on the right in the lower region of
The second floor bolt 13 which is of substantially mirror-symmetrical configuration to the first floor bolt 11 is illustrated at the bottom on the left in
The limbs 112 and 132 each have a length of 50 millimeters to 200 millimeters, a width, for example, of 10 millimeters (in the closing direction S) and a thickness of, for example, 30 millimeters to 40 millimeters (in the pass-through direction D), wherein said thickness depends on the corresponding thickness of the vertical profiles 40, 60. By means of this solid construction, the limbs 112 and 132 are introduced deeply into the vertical profiles 40, 60 and the corresponding vertical terminating profiles 68. By means of this configuration, the frame 68, 69, 60 of the sliding wing 4, 6 is stabilized and the guiding of the sliding wing 4, 6 in the floor guide profile 150 is ensured by means of the engagement elements 118, 138. In addition, it is efficiently prevented that the sliding wing 4, 6 is pushed or pulled transversely with respect to the running direction thereof out of the intended position.
Furthermore, the second vertical closing edge 6a of the vertical profile 60 is illustrated at the top on the right in
The U lock plate 22 is accommodated in the vertical profile 40 which is not illustrated in
The closing mechanism will now be explained with reference to
For this engagement, engagement recesses 291, 292 are in each case provided in the closing strip 29. One recess 291, 292 is preferably provided per bolt 211, 231. Since the closing strip 29 is attached in a vertical chamber 63 in the ridge 61 (see below), the ridge 61 has apertures at the locations of the recesses 291, 292 of the closing strip 29 such that the bolts 211, 231 can engage in the ridge 61 and in the closing strip 29 located therebehind.
The pivoting bolt 211, 231 is therefore pivoted through the recess 291, 292 to behind the closing strip 29. By means of the hook-like design of the pivoting bolt 211, 231, the pivoting bolt 211, 213 can engage behind the closing strip 29. The closing strip 29 is fixedly attached on or to the second vertical profile 60 (in the ridge 61). The vertical profiles 40, 60 can therefore be fixed in relation to each other by means of the pivoting bolts 211, 231 and the closing strip 29, and therefore an opening movement of the sliding wings 4, 6 (in particular along the closing movement) is prevented.

By means of the U lock plate 22, the sliding blocks 220 and the holding plate 24, the pivoting bolt cases 21, 23 are fixed in the vertical profile 40 at the rear and front in a form-fitting manner with respect to a direction parallel to the closing direction S, which will now be described with reference to the following
The outer flank 41a and the inner flank 41b can be seen in
When the two vertical closing edges 4a, 6a are in close contact with the ridge 61, the flanks 41a, 41b engage over each other in such a manner that unauthorized access via the main closing edge H (i.e. the vertical closing edges 4a, 6a) to parts of the closing device 20 (for example by means of a lever tool, such as a crowbar) is made more difficult, which has a burglary-resistant effect. A vertically running gap 41e (see

So that the pivoting bolts 211, 231 can engage in the recesses 291, 292 of the closing strip 29, the ridge 61 at the appropriate points has pass-through openings from the outside through the recesses 291, 292 into the partial chamber 63.
It is apparent in
The vertical profile 40 is illustrated on the right side in
For the vertical securing of the holding strip 24, screws 293 running substantially horizontally pass through the holding strip 24 from the front to the rear, wherein the screws 293 protrude to the rear via the holding strip 24. A back wall of the vertical partial chamber 44b can then have threaded holes (or can provide corresponding means) in which the holding strip 24 is secured by means of screws 293. The holding strip 24 can also be secured vertically in another manner obvious to a person skilled in the art. It is also possible for a plurality of holding strips 24 (and/or closing strips 29) to be provided in the vertical profiles 40 (or in the profile 60), depending on the number of pivoting bolt cases.

The sliding wing 6 is fastened to two running carriages 32 above the upper horizontal profile 33 which extends substantially horizontally between the vertical terminating profile 68 and the second vertical profile 60. For this purpose, a secure screw connection-screws 313 is preferred.
For the suspension of the sliding doors 4, 6, a stationarily secured running profile 31 is provided with a rail profile 30 (see in particular
If the sliding wing 6 in the view according to
In order to limit the freedom of movement upward to a region which does not permit such a disengagement, a first anti-prying-open means 322 is provided in the form of a metal plate 322 which protrudes upward from the running carriage body of the running carriage 32 and limits the abovementioned lifting-out movement of the wing 6 upward (see
The running carriages 32 make contact with the running profile 31 in a manner rolling over the rail 311 which is provided on a limb 310 of the running profile 31, said limb protruding horizontally from the running profile 31 and running parallel to the closing direction S. The running carriage 32 then at least partially extends upward with the running carriage body in front of the limb 310 (as described above) and also to under the limb 310 via a wing adaption bracket 34 (see
As can be seen in
The substantially U-shaped adaption bracket 34 engages here downward around the second anti-prying-open means 324 and is guided upward again behind the second anti-prying-open means 324 (on the left in
By means of the above-described blocking of lifting and/or pivoting movements of the wing 6 (and in the same manner also of the wing 4), it is prevented that the floor bolts 11, 13 are levered out of the guide chamber 151, which increases the security against intrusion and stability of the system 1.
By means of the first and second anti-prying-open means 322, 324, prying open of the sliding wing, in particular in interplay with the above-described floor bolts which are guided along the closing movement in the floor guide 150, 160, is effectively made difficult.
In addition, the accessibility to screws or other elements in the region of the running profile 31 is additionally made difficult by the adaption bracket with the section 341 drawn upward to the rear, which further increases the security of the device against intrusion.
