Description

The present invention relates to a Schiebefenster- and / or sliding door system, in particular lifting sliding door system, with a locking system for burglar resistance and for use in strong wind loads on the Schiebefenster- and / or sliding door system. The invention further relates to a locking system as such for a sliding window and / or sliding door system, in particular lifting sliding door and / or lifting sliding window system.

A Schiebefenster- and / or sliding door system generally has at least two window and / or door elements, which are also referred to below as wings. In sliding systems of this kind, at least one movable sliding leaf and at least one further wing, which may for example also be a sliding leaf or a fixed passive leaf, are provided. This means that the sliding leaf has a displacement device which allows a translational Relatiwerschiebung with respect to the other wing, In a lift-and-slide system, a lifting slide unit is provided at least on one of the wings, which makes it possible to lift this wing and then to move linearly. Such wings usually have a sash profile frame, which has on a floor or subfloor facing the underside of the profile frame a carriage which is to be placed on a running rail to lift the wing and to translate. For example, at least one pair of carriages or at least two separate carriages connected by a connecting rod can be used. After a sliding movement of the wing this can be lowered again, i. that the carriage is retracted again and further movement of the wing is prevented. The wing profile frame may also comprise two vertical beams, one of which has a closing device for closing the wing in the frame and the other, usually the central vertical spar in the so-called middle closure region is formed without closing device, this Mittelvertikalholm overlaps when moving the one wing relative to a other, adjacent wings with a central vertical spar of the other wing. Due to the fact that no closure device is provided in the middle closure region, but as a rule only one sealing device with two profile strips, this region is particularly susceptible to burglary attempts and to high wind loads which can act on a wing surface. In order to realize an anti-burglary, it is among other things necessary to secure the sliding wing against unauthorized levering or lifting from the lowered position. Nowadays, this need is compounded by the increasing demand for ever lower door sills or rails. As a running rail while a bottom, near-floor bar a sliding door or a sliding window is called, which leads the sliding door or the sliding window in the linear displacement movement. For this purpose, the strip generally has a guide nose projecting upwards in the vertical direction which, in the lowered position of the sliding door or the sliding leaf, engages in a groove provided in the underside of the sliding door or the sliding leaf and in both the raised sliding position and in the lowered position Position of the door or window is surrounded by the carriage. Usually white rails have a height of 15 mm. In so-called "barrier-free" sliding door systems and sliding window systems, the vertical height of the guide lug is increasingly reduced, for example to less than 8 mm, in particular 5 mm or even 3 mm. A burglar is thereby facilitated to lift the sliding door or window from the lowered position above the vertical height of the guide tab and thus lift it out of the guide to the sliding door or window from the other door or the other window of the sliding door or window Sliding window system to remove. Furthermore, high wind loads can cause the wing to bend so that it is pushed out of the guide provided in the door sill. Both sliding systems and lift-sliding system, it is possible that the two wings in the area of overlapping vertical bars in the central closure area move away from each other due to external load, so that destruction of the sliding system or the lifting slide system can go hand in hand and / or that is a passage for a person can be created. In order to counteract the described problems, specially designed fittings or additional burglar alarms are already being used.

A well-known burglar alarm, as for example EP 2 476 829 is disclosed, has two mutually engageable latch members, of which a female latch member in the door threshold and a male latch member in the region of the door sill facing the underside of the wing are provided. The male control part in turn consists of a plastic block, which is mounted in the wing, and a screwed into the plastic block pin. The female latch member is formed substantially as a hollow profile with a slot or a recess into which the pin engages to prevent vertical Aushebelns the wing of the door sill. However, such a system requires complex adjustments to the threshold and at the bottom of the wing. This means that such a backup can only be used systemically. Furthermore, this backup due to the transfer small engaging surfaces only a slight force, so absorb only a slight force, for example, by a burglar from the outside, without being destroyed.

It is therefore an object of the invention to overcome the disadvantages of the prior art, in particular to provide a Schiebefenster- and / or sliding door system that is safer against external force, for example by burglary attempts or by high wind loads and withstands reliable external force even with barrier-free versions , It is a further object of the present invention to provide a flexibly deployable locking system that can withstand safe and reliable external force even when used in barrier-free sliding window and / or sliding door systems. In particular, the Schiebefenster- and / or sliding door system and the locking system to prove the burglary classes RC2 and RC3 (when tested using tools according to DIN EN 16 27 to DIN EN 16 30) as well as for the proof with high wind loads, for example class 5 (according to DIN EN 12 210 and DIN EN 12 211 ), serve.

This object is solved by the features of independent claims 1, 8 and 11. Preferred embodiments are given in the subclaims.

According to the invention, a sliding window and / or sliding door system, in particular a sliding and sliding window system, is provided. The sliding window and / or sliding door system according to the invention comprises at least two wings, of which at least one is movable, i. linearly displaceable, designed as a so-called sliding sash. The at least one further wing can also be designed as a sliding wing with the same linear direction of movement. Alternatively, the at least one further wing may be a so-called fixed wing, i. fixed wing, his. Each wing has a preferably encircling wing profile frame, wherein the wing profile frame preferably consists of pairs mutually perpendicular uprights. The wing profile frame usually has a vertical pair of hollows and a horizontal pair of hollows, wherein a horizontal spar is perpendicular to the vertical spar, so that the wing profile frame forms, for example, a square or right-wing structure. A wing therefore preferably has a rectangular wing surface. The sliding leaf is translationally displaceable relative to the other sliding leaf or to the inactive leaf for opening and / or closing the sliding window and / or sliding door system that a vertical spar of the sliding leaf can overlap or overlap with a vertical spar of the further wing in a direction perpendicular to the direction of displacement locking direction , In a closed system state, such as closed state, the sash vertical substantially completely overlaps with the vertical sash. However, it is not necessary that the vertical beams completely overlap. The overlapping vertical bars are preferably the vertical bars in the so-called middle closure area, that is to say the central vertical bars. In a development of the invention, the vertical struts can be the middle vertical struts in the middle closure region of two mutually displaceable wings. In a Schiebefenster- and / or sliding door system according to the invention are mainly plastic profile frame application, with other profile frame materials are conceivable. Such a profile frame is generally used to surround a glass, in particular insulating glass. Furthermore, the profile frame serves as an interface with other system components, for example, to receive the carriage and the locking device. With a relative displacement of two wings of the sliding sash goes to another wing, usually the inactive leaf, over. This means that a sliding leaf and an adjacent stationary leaf or sliding leaf are arranged offset in the locking direction to each other, ie in a horizontal direction.

The sliding window and / or sliding door system also includes a locking system for preventing removal of the wings in the locking direction to lock the sliding window and / or sliding door system, in particular to lock two wings of the sliding window and / or sliding door system together. The locking system has a first, in particular male, locking part which is mounted on a vertical spar of a first wing, in particular a sliding leaf. In addition, a second, in particular female, locking part is provided which is mounted on a vertical spar of a second wing, in particular a fixed leaf. According to the invention, the first and the second locking part are located on the vertical bars which overlap in the direction of displacement. The first and the second locking part can be designed such that they can be mounted flat on an outer side of the sash profile frame. It is a simple installation allows that requires no modification standard used sash frame or door sills or rails. The locking system is thus flexible to a large part of the wing profile frame available on the market. The assembly can be done by all possible assembly processes. For example, the locking parts can be screwed to the respective vertical spar. This allows, as already mentioned, a simple assembly and a flexible application, since only a substantially flat, flat surface to enable the attachment of the locking part is necessary. In the case of plastic profile frames, additional stiffeners, in particular of metal or steel, aluminum or polyamide core, are preferably used, in which the locking parts are screwed in order to ensure increased stability against tearing.

With a relative displacement of the sash with respect to the inactive leaf, or the further sash, i. with a relative displacement of the first locking part with respect to the second locking part, the locking parts can also overlap in the locking direction. According to the invention, the first and the second locking part are adapted to one another in such a way that when the sliding leaf is moved into the closed position, i. in the closed state of Schiebefenster- and / or sliding door system, reach each other in a locking engagement. The co-tuning of the first and second latch members includes structuring the respective latch members and placing them on the vertical beams. The structure or arrangement is to be tuned such that a blocking in the locking direction is accompanied by the locking engagement. The engagement of the first locking part with the second locking part thus realizes a locking of the two locking parts with each other and thus also a locking of the overlapping vertical bars in the middle closure area. The force which a burglar has to apply to separate the overlapping vertical struts and the ability to withstand a force due to high wind loads can thereby be significantly increased. Such a locking intervention can therefore ensure that proof of the test classes RC 2, RC 3 can be achieved in burglar resistance and class 5 for wind loads.

In the exemplary embodiment, the first and the second locking part are so matched to each other, in particular the arrangement and / or the vote of the first and second locking member relative to each other to make such that they brace when taking the locking engagement against each other in the locking direction to the overlapping Add vertical beams to each other. This means that in the closed position of the movable sliding leaf, ie in the closed state of the sliding window and / or sliding door system, a force due to the locking engagement between the first and the second locking member is caused, which causes a pulling on the locking parts and thus the overlapping vertical beams , It can be provided to structure the first and second locking part such that, for example, based on the direction of displacement oblique ramp surfaces, a gradual buildup of Zuziehkräfte between the locking parts is achieved. Furthermore, the locking parts can be coordinated with each other so that they align with each other to each other, in a direction transverse to the locking direction and the direction of transverse direction, in particular vertical direction. For example, inlet radii can be provided for this, which ensure a safe collision.

According to an exemplary embodiment, the locking system is designed to receive in the locking engagement a load in the locking direction in the amount of at least 3 kN, in particular 4 kN, 5 kN, 6 kN, 7 kN, 8 kN, 9 kN or 10 kN. This means that the first and the second locking part can be dimensioned and executed so strongly that loads of at least 3 kN, in particular 4 kN, 5 kN, 6 kN, 7 kN, 8 kN, 9 kN or 10 kN, between the engaged locking members can be transferred without causing a fracture of any of the locking members or the fasteners on the vertical beams or to a plastic deformation of the locking members. The load resistance is in any case so high that the above-mentioned forces are endured. These forces can be caused, for example, by burglary loads by means of crowbars or by gusts of wind which attack the entire surface on the respective wing. For example, materials such as metal, in particular steel, or preferably hard plastics with adequate strength properties, can be used to support these high forces. The particular configuration of the integrally formed first locking part with the likewise integrally formed second locking part will be explained further below, in particular to endure the high load forces. For example, the first locking part may have a locking tongue which engages with a locking pocket of the second locking part. In an exemplary embodiment, a length of the locking tongue in the direction of displacement in the range of 10 mm to 40 mm, preferably in the range of 15 mm to 35 mm, preferably in the range of 20 mm to 30 mm. A width of the locking tongue in the transverse direction may be in the range of 5 mm to 40 mm, preferably in the range of 10 mm to 35 mm, preferably in the range of 15 mm to 30 mm, or in particular 20 mm. A depth of the locking tongue in the locking direction is for example in the range of 2 to 10 mm, preferably in the range of 3 to 8 mm, preferably in the range of 4 to 6 mm. In a further exemplary embodiment, a length of the locking pocket in the direction of displacement in the range of 10 mm to 40 mm, preferably in the range of 15 mm to 35 mm, preferably in the range of 20 mm to 30 mm. A width of the lock pocket in the transverse direction can in Range of 10 mm to 50 mm, preferably in the range of 15 mm to 45 mm, preferably in the range of 20 mm to 40 mm, preferably in the range of 25 mm to 35 mm. A depth of the locking pocket in the locking direction is for example in the range of 2 to 10 mm, preferably in the range of 3 to 8 mm, preferably in the range of 4 to 6 mm. However, it is clear that the dimension of the locking tongue and the locking pocket must be matched to one another such that a locking engagement can be ensured. Furthermore, it should be noted that in a lift-and-slide window system, the lock pocket must always be larger in transverse direction, preferably at least 2 mm, in particular at least 5 mm, than the lock tongue to ensure lifting of the lift slide wing. Preferably, the locking pocket in the transverse direction may be at most 50 mm, 40 mm, 30 mm, 20 mm or at most 10 mm larger.

In an exemplary embodiment, the first locking part and the second locking part are mounted on an outer surface of the respective vertical spar, in particular in the middle closure region, which face each other when overlapping the vertical sliding leaf spar and the vertical vertical leaf wing or the vertical sliding leaf vertical spar. The outer surfaces may face one another and in particular may be flat and step-free or may be provided with a depression, such that a flat support of the respective locking part is achieved. It should therefore be the mounting surface, which is in particular the mounting surface of the locking member, which is in particular made completely flat, be applied over the entire surface on the outside of the vertical beam. The flat support is formed in particular steplessly between a respective mounting surface and the flat, planar outer surface of the respective vertical spar. This means that the vertical Holmmontageflächen face each other when the vertical beams overlap in the direction of displacement. It is possible that the vertical hollow mounting surfaces are oriented parallel to each other and in particular formed congruent. This means that the first locking part and the second locking part are positioned in a gap area between the mutually offset and mutually displaceable wings. Since this gap area is the area that must be sealed against noise and other external influences, this is usually chosen as small as possible. Therefore, it is necessary that the locking system, that is, the second and the first locking part, is formed very narrow / are. Preferably, the locking system has a total depth, i. a dimension in the transverse direction of less than 25 mm, preferably less than 20 mm, preferably less than 15 mm, preferably less than 10 mm. Due to this flat shape of the locking system, it can be mounted in the gap area between the overlapping vertical beams so that no costly or unnecessary modifications of the profile frames and / or the door sills, i. the rails, the Schiebefenster- and / or sliding door system are necessary.

The locking system according to the invention is to be arranged in the transverse direction with respect to the respective vertical members in a region in the lower half, in particular of the lower third, of the vertical spar of the respective wing. In particular, the locking system is flush with the floor at a height from a bottom side of the sliding window and sliding door system, in particular in the range of 0 cm to 30 cm, preferably in the range of more than 10 cm to at most 150 cm, in particular from 20 cm to 130 cm, in particular from 30 cm to 100 cm. In particular, the distance from the guide rail, in which the respective wing is guided, starting up to the vertical height, i. in the transverse direction, the arrangement or attachment of the respective locking member to the respective vertical spar measured. It is clear that the attachment of the first and second locking part must be matched to the respective vertical spar to realize the locking engagement can.

In a further development of the invention, at least two locking part pairs can be provided. In this case, a pair of locking elements comprises a first and a second locking part, each of which can be designed and matched to one another as described above. Preferably identically formed locking part pairs are used. The first locking part may be designed as a male locking part, wherein the second locking part should be designed as a female locking part. The male and female locking members reciprocate in different directions to realize the locking engagement. The male locking part and the female locking part each have mutually matched locking surfaces, which should be parallel to each other and in particular lie in the same plane, such as the areal extent of the wings and the direction of displacement. In the retracted locking engagement, the locking surfaces of the male and female locking members are diametrically opposite and / or in contact, so that there is a blockage due to the overlapping and / or in contact locking surfaces in the locking direction. Preferably, a female and a male locking member form a locking member pair. In a further development of the invention, a plurality of locking-part pairs can be used directly structurally together. This means that, for example, several male Locking pieces, which are made of one piece, with several female locking parts, which are also formed from one piece, cooperate to increase the maximum blocking load of the locking system according to the invention. Alternatively, the locking piece pairs can be made separately from each other and attached separately to the respective vertical beams. For example, two adjacent pairs of locking pieces can immediately close to each other. This means that two separately formed locking-part pairs in the vertical direction, ie in the transverse direction, for example, are arranged touching each other in succession. Adjacent locking member pairs may, however, also be distributed uniformly along the lower half of the vertical spar, or along the lower third of the vertical spar, in particular without touching each other.

In an exemplary embodiment, the first and the second locking part are matched to one another and / or dimensioned relative to each other, that in the locking engagement, a lifting movement amplitude of at least 3 mm, preferably 5 mm, 8 mm or 10 mm, between the locking parts in a locking direction and transverse to the direction of displacement, in particular vertical, lifting direction is allowed. The lifting direction is essentially the same as the transverse direction. Preferably, a lifting movement amplitude limit, that is to say a maximum value of the lifting movement amplitude, is to be matched to a vertical height of the door sill, in particular of the running track of the door sill. The lifting movement amplitude is preferably to be selected so that the lifting slide wing can be raised from the lowered to the extended displacement position while maintaining the locking engagement between the two locking parts, ie in particular to ensure an extension of the carriage. However, the lifting movement amplitude should be limited so that a further lifting of the lifting slide wing is such that the carriage can be raised via the guide rail is not guaranteed. If, for example, the lifting amplitude of the carriage is 5 mm and the height of the running rail is 8 mm, the lifting movement amplitude is in the range of 5 mm to 13 mm, which corresponds in particular to the sum of the lifting amplitude of the carriage and the height of the running rail. The lifting movement amplitude limit is achieved, in particular, when the locking tongue abuts or strikes against a wall of the locking pocket facing the locking tongue. Exemplary hoist travel amplitude limits are at most 50 mm, 40 mm, 30 mm or at most 20 mm.

According to a further aspect of the invention, which can be combined with the previous features, a locking system for a sliding window and / or sliding door system, in particular lift-and-slide door system, is provided. In general, the locking system should be designed to block a removal of two wings of the sliding window and / or sliding door system in a direction transverse to the planar extent of the wing transverse, in particular vertical, locking direction. In an exemplary embodiment, a displacement direction of the at least one movable sliding leaf corresponds to the planar extent of the wings. The locking system comprises a first locking part with a mounting surface for attachment to a wing and at least one locking surface, wherein a plurality of in particular separate locking surfaces can be provided. Furthermore, the locking system also comprises a second locking part with a mounting surface for attachment to another wing and also at least one locking surface, wherein the second locking part may also have a plurality of, in particular, separate locking surfaces. Separately means, in particular, that the separate locking surfaces can be interrupted by a movement limit stop which connects two adjacent locking surfaces. For example, a free space or a material web can be formed between two adjacent locking surfaces. The two locking parts are designed to come about a linear movement relative to each other in a locking engagement. The locking engagement is realized in that associated locking surfaces of the first locking part and the second locking part overlap each other or overlap in a direction perpendicular to the linear movement direction locking direction. The linear movement direction may correspond to the above-mentioned direction of displacement. Retraction into the locking engagement is such that a coverage area of the associated locking surfaces gradually increases. That is, the coverage area becomes steadily larger, in particular continuously, from 0 to a maximum. This ensures that increases with increasing retraction into the locking engagement, the recordable load, in which no plastic deformation or even destruction of one of the locking parts or the fasteners used, increases in the locking direction. The locking surfaces and the mounting surfaces, in particular all locking surfaces and all mounting surfaces, the locking parts are parallel to each other. Furthermore, the surface extension of the wings, in particular the sliding sash and the adjacent thereto wing, the Schiebefenster- and / or sliding door system parallel to the locking surfaces and the mounting surfaces, in particular to all locking surfaces and all mounting surfaces lie. In this way, a very narrow, flat locking system is formed, since the respective surfaces are parallel to each other and in Locking engagement the mounting surfaces and the locking surfaces in the locking direction are largely one above the other, as in a kind of sandwich structure. Advantageously, the extent of the locking system in the locking direction has a dimension smaller than 25 mm, 20 mm or 15 mm, whereby the locking system can be arranged even in the smallest gaps, especially between the wings of a sliding window and / or sliding door system, without this outside the locking engagement is in a sliding contact. The particularly narrow feasibility of less than 25 mm can be achieved in that the locking parts is formed as a combination of at least one male and at least one female locking part, wherein the female locking part together with the outside of the vertical spar forms a Einfahrasche or - recording, in which the male locking part can retract. In this case, the male locking member has a locking surface, which is arranged at a distance to the outside of the vertical spar in the assembled state, to allow a retraction into the entrance pocket of the female locking member. The locking engagement itself will be described in detail later.

If several male and female locking parts interact with each other, all male locking parts are preferably realized in a single piece, in particular a piece. The same applies to the female locking part with several entry pockets.

Preferably, the linear movement direction, the locking surfaces and the mounting surfaces are parallel to each other. Alternatively or additionally, all locking surfaces and / or mounting surfaces of the first locking member and all locking surfaces and / or mounting surfaces of the second locking member may be parallel to each other. In particular, the parallelism of the locking surfaces is to be understood in that the locking surfaces and the mounting surfaces are arranged offset in the locking direction to each other, in particular, an offset less than 2 cm, preferably 1 cm, or in particular should be 0.5 cm. As a result, the narrow executability of the locking system is enhanced. Furthermore, at least one locking surface of the first locking part can have at least one transverse web extending in the displacement direction and / or at least one locking surface of the second locking part having a transverse groove extending in the direction of displacement. The at least one transverse web and the at least one transverse groove are preferably matched to one another such that the at least one transverse web can engage in the at least one transverse groove. The at least one transverse webs can preferably engage in the at least one transverse groove in such a way that a resistance in the direction of displacement when moving in and out of the locking engagement is suddenly increased or reduced. As a result, it is possible, inter alia, to obtain a haptic and / or acoustic feedback on the progress when entering the locking engagement and extending out of the locking engagement. Alternatively, the locking surfaces of the first and the second locking member may be realized as substantially flat, smooth surfaces, so that a uniform retraction is ensured in the locking engagement with constant frictional resistance. In particular, the transverse webs or transverse grooves are formed integrally with the respective locking part, preferably by machining or forming molding techniques.

In a further development, the mounting surface of the first locking part and the mounting surface of the second locking part in the locking direction away from each other. This is due to the fact that the wing surfaces to which the locking parts are to be mounted, facing each other in the locking direction and the locking system is to be mounted in the gap region between these wing surfaces facing each other.

According to a further aspect of the invention, which can be combined with the previous features, a locking system for a lift-and-slide door and / or lift-and-slide window system, hereinafter referred to as a lift-and-slide system, is provided. In general, the locking system should be designed to block a removal of two wings of the lift-and-slide system in a direction perpendicular to the planar extension of the wings, in particular vertical, locking direction. In an exemplary embodiment, a displacement direction of the at least one movable sliding leaf corresponds to the planar extent of the wings. The locking system comprises a first locking part with a mounting surface for attachment to a wing and at least one locking surface, wherein a plurality of in particular separate locking surfaces can be provided. Furthermore, the locking system also comprises a second locking part with a mounting surface for attachment to another wing and also at least one locking surface, wherein the second locking part may also have a plurality of, in particular, separate locking surfaces. Separately means, in particular, that the separate locking surfaces can be interrupted by a movement limit stop which connects two adjacent locking surfaces. For example, a free space or a material web can be formed between two adjacent locking surfaces. The two locking parts are designed to come about a linear movement relative to each other in a locking engagement. The Locking engagement is realized in that associated locking surfaces of the first locking part and the second locking part overlap each other or overlap in a direction perpendicular to the linear movement direction locking direction. In particular, the locking engagement is to be understood in that a displacement of the first locking part to the second locking part in the direction of displacement is not possible because a stop is reached. However, this existing stop in the direction of displacement still allows a relative displacement of the locking parts in the transverse direction, in particular by at least 5 mm, preferably 6 mm, 7 mm, 8 mm, 9 mm, 10 mm or more than 10 mm.

In the locking engagement, a lifting movement amplitude of at least 3 mm, preferably 5 mm, 8 mm, or 10 mm, between the locking parts in a direction transverse to the locking direction and Liniarbewegungsrichtung, in particular vertical, lifting direction is allowed. Preferably, the lifting direction coincides with the transverse direction. This relative movement play in the transverse direction between the locking parts is necessary to lower a lifting slide wing in the locking engagement in its closed position or to lift out of the closed position. The required lifting movement amplitude depends on the lifting slide device and / or on a height of the door sill or the running rail for the lifting sliding sash in the transverse direction.

An overlapping region of the associated locking surfaces of the first and second locking parts arising during retraction into the locking engagement increases in particular continuously up to a locking end position to a maximum. This means that the maximum of the overlapping area is reached in the locking end position of the locking parts. The locking surfaces according to the invention form the overlap region, which causes the desired blockage in the locking direction due to the fixed mounting of the locking parts on the vertical bars. According to the invention, the locking surface, which realizes the blockage, increases in the direction of displacement and reaches a maximum in the locking engagement when the movable sliding leaf of the sliding window and sliding door system is in the closed position, i. in the lock end position. Then there is also the highest blockage effect of the locking system.

In an exemplary embodiment of the locking system, the first locking part, in particular male locking part, a tongue carrier and at least one extending from the tongue carrier from tongue, in particular locking tongue, on. For example, the first locking part is made of one piece, preferably of metal, using, for example, metal-cutting or original-forming production techniques, such as casting, in particular injection molding in plastics. However, the at least one tongue and the tongue carrier can also be attached to one another as separate components, for example screwed, welded or joined. In any case, it must be ensured that the first locking part is dimensioned or designed to be so strong that it can absorb or transmit the loads occurring in the event of break-ins or strong wind loads. Preferably, the tongue extends in the direction of displacement, in the direction of the second locking part. In particular, the tongues are held by a transversely extending cross member or bridge girder. The main extension direction of the tongue can extend transversely, preferably perpendicularly, to the main extension direction of the tongue carrier. This means that the tongue carrier, ie cross member or bridge carrier, provides a type of bridge function which allows forces to be transferred from one tongue to another and to achieve retraction of the protruding tongues in the direction of displacement into the locking engagement. Furthermore, the tongue carrier serves in particular as a stop or buffer element, specifically to limit the displacement movement when the tongue carrier comes into contact with the second locking part. The displacement movement corresponds to the main extension direction of the tongue.

In an exemplary embodiment, the first locking part has two, preferably three, four or five, in particular identically formed tongues, which each extend away from the tongue carrier. In an arrangement with at least three tongues, a distance between two adjacent tongues can always be the same and preferably in the range of 10 mm to 40 mm, in particular in the range of 15 mm to 35 mm, in particular in the range of 20 mm to 30 mm. Each tongue can then form a locking surface of the first locking part on an associated transverse tongue underside. Preferably, all locking surfaces are formed by the tongues. Furthermore, the tongue carrier can be free of locking surfaces. In the assembled state of the first locking part on a vertical beam, the tongue extends in the direction of displacement and the tongue carrier exactly perpendicular thereto, that is in the transverse direction. Furthermore, a tongue underside may have at least one transverse web extending in the direction of displacement.

In an exemplary embodiment of the tongue carrier is preferably a flat, elongated plate, in particular mounting plate, formed, wherein a plate underside, which in particular has in the locking direction, the mounting surface of the first locking member. The mounting plate may also be formed thin-walled, wherein Wall thicknesses in the range of 2 mm to 5 mm are preferable. The mounting plate and the mounting surface are executed in the locking direction offset from the tongues, so that in the assembled state of the mounting plate on the vertical spar, the tongue is free from engagement or contact with the vertical spar This is necessary insofar as the locking tongue in a locking pocket of the female Locking parts should retract, with as possible when retracting the contact between the locking surfaces should be low. Only in the locking engagement of the surface contact should exist. Preferably, one, two, three or more locking tongues are arranged on a mounting plate, which extend in a comb-like or tine-like manner away from the mounting plate of the male locking part.

In a further development of the locking system, the second locking part, in particular the female locking part, a mounting plate, also referred to as base, and at least two extending from a base base in the locking direction and at a distance from each other, preferably identically formed feet, especially support feet, on. For example, the second locking part is made of one piece, preferably made of metal, using, for example, machining or forming primary manufacturing techniques. Alternatively, the at least two feet and the base may also be attached to one another, for example screwed, welded or joined. The base may also be formed thin-walled, with wall thicknesses in the range of 2 mm to 5 mm are preferable. However, it must also be ensured here that the loads occurring during the use of the locking system can be absorbed or transmitted in the locking direction by the second locking part. In an exemplary embodiment, in an arrangement of at least three Abstutzfüßen each two adjacent feet and the mounting plate underside define a tongue receptacle, in particular locking pocket or entrance pocket. Furthermore, a tongue receiving underside can have at least one transverse groove extending in the direction of displacement. The at least one transverse web of the tongue and the at least one transverse groove of the tongue receptacle are preferably matched to one another such that the at least one transverse web can engage in the at least one transverse groove. The at least one transverse webs can preferably engage in the at least one transverse groove in such a way that a resistance in the direction of displacement when moving in and out of the locking engagement is suddenly increased or reduced. As a result, it is possible, inter alia, to obtain a haptic and / or acoustic feedback on the progress when entering the locking engagement and extending out of the locking engagement. Alternatively, the tongue receiving underside and the tongue receiving underside can be realized as substantially flat, smooth surfaces, so that a uniform retraction is ensured in the locking engagement with constant frictional resistance. In particular, the transverse webs or transverse grooves are formed integrally with the respective locking part, preferably by machining or forming molding techniques.

In an exemplary embodiment, the base is designed as a preferably flat, elongated plate, wherein in particular a plate underside facing the tongue receptacle and pointing in the locking direction forms a locking surface of the second locking part. Alternatively or additionally, in each case one support foot underside, which also points in the locking direction, forms a separate mounting surface of the second locking part. The individual locking surfaces are separated from one another by support feet, wherein for at least one locking pocket into which a locking tongue of the male locking part is intended to engage, at least two support feet extend essentially in the direction of displacement.

In a further development of the invention, the at least one tongue, in particular locking tongue, in relation to the at least one tongue receptacle, in particular locking pocket, dimensioned such that the tongue is retractable into the tongue receptacle up to a Verriegelendposition. Due to the support legs, which are dimensioned the same in the locking direction, the locking pockets are formed, which are bounded on the one hand by the outside of the vertical spar, each of the transversely adjacent and staggered support feet and the locking surface of the mounting plate. The locking tabs enter the locking pockets in order to realize a blockage in the locking direction. The distance of the support feet in the transverse direction is to be designed such that the correspondingly wide-shaped locking tongues should have a freedom of movement in the transverse direction of at least 3 mm, preferably 5 mm or 8 mm. The locking pocket, which limits the locking surfaces of the female locking part on one side, is made so flat in the region of the locking surface that free movement of the locking tongue with its locking surfaces in the transverse direction can be accompanied by sliding movement. Preferably, the overlapping area of the locking surfaces of the first and second locking part continuously increases when retracting the at least one Verrieglzunge in the at least one locking pocket up to a Verriegelendposition in which the overlap maximum is reached, in particular the overlap maximum at least 10 cm ² , 15 cm ² , 20 cm ² , 30 cm ² , 40 cm ² , 50 cm ² , 70 cm ² , 100 cm ² , 150 cm ² , 200 cm ² , 300 cm ² , 400 cm ² , 500 cm ² , 700 cm ² , 900 cm ² , and should be less than 1000 cm ² executed. It is clear that the larger the overlap area of the Locking surfaces is, the more force can be transmitted from the two locking parts, that is, the more load the locking system can withstand, without any plastic deformation or destruction of the locking system is accompanied.

In an exemplary embodiment, one foot each has a tine, whose tine seat facing tine inside and / or tine outside is formed obliquely and its adjacent to the tine inside tine top is also formed obliquely, so that the tine inside and the tine top open into a common tine tip and a tine cross section preferably decreases continuously towards the tip of the tine. In other words, the supporting feet extending in the direction of displacement are wedge-shaped in order to realize a simple retraction when the locking tongues are not exactly aligned. Due to the support legs, which are arranged on the vertical spar side of the mounting plate, a reinforced material portion is formed in the openings and holes are provided to attach screws there to rigidly attach the second locking member to the vertical beams. Preferably, a corresponding passage is provided on each of the Abstützfußbereiche to occupy this with a screw or other fastening means. In an exemplary embodiment, the tines in the locking end position, the tongue carrier under run such that the first locking member and the second locking member in the locking engagement are braced against each other. This means that in the locking engagement, a force between the first and the second locking part is caused, which causes a pulling on of the locking parts in the locking direction. This can be achieved by making the prong wedge-shaped as described above and, in particular, the prong top obliquely as a kind of abutment surface to effect a gradual build-up of a tightening force between the interlocking members.

In an exemplary embodiment, the locking surface of the tongue on a Anfahrschräge. Furthermore, the locking surface of the tongue receptacle may also have a ramp. Both the approach slope and the ramp make it easier to retract the tongue into the tongue receptacle when the tongues and tongue receptacles are not exactly aligned with each other. Furthermore, the approach slope and the run-up ramp cause the two locking parts to be pulled together, but here in the transverse direction, when the locking engagement takes place. This has the advantage that an increased sealing effect is achieved in the intermediate region between the vertical beams. Furthermore, this reduces the gap width between the vertical beams, so that there is less space for attaching tools, such as chisels, during break-ins. For example, a chamfer angle is in the range of 5 ° to 45 °, preferably in the range of 10 ° to 40 °, preferably in the range of 15 ° to 35 ° or in particular 20 °, 25 ° or 30 °. For example, a ramp angle is in the range of 5 ° to 45 °, preferably in the range of 10 ° to 40 °, preferably in the range of 15 ° to 35 ° or is for example 20 °, 25 ° or 30 °. In such an embodiment of the approach slope or the ramp, a gradual buildup of the closing force between the locking parts when taking the locking engagement is achieved up to the Verriegelendposition.

In an exemplary embodiment, the locking system is configured to receive a locking and / or transverse force of at least 3 kN, preferably 4 kN, 5 kN, 6 kN, 7 kN, 8 kN, 9 kN, or 10 kN in the lock end position In particular, the first locking part is jammed with the second locking part when an external force occurs in the locking engagement. However, it is clear that the transmission of power in the transverse direction takes place only after the permissible lifting movement amplitude has been overcome. Only when the first locking part has been displaced in the transverse direction relative to the second locking part such that the lifting movement amplitude is overcome and the tongue of the first locking part comes into contact with the support foot of the second locking part, the locking system receives a force in the transverse direction. Advantageously, the two locking parts wedge or jam between respective stop point pairs, wherein a stop point pair is formed by the top of the tongue and the vertical spar outer surface and another stop point pair through the underside of the second locking member and the tongue bottom of the first locking member. In this way, the recordable or transferable load in the locking direction and / or in the transverse direction can be increased without causing any plastic deformation or even destruction of one of the locking parts, the mounting section on the vertical spar or one of the fastening means.

With reference to the 1 to 12b exemplary embodiments of a locking system according to the invention are described, wherein the interaction and the operation of the individual components of the locking system based 1 , two and structural details as well as various alternatives thereof on the basis of 3 to 12b be explained. The 13 to 15b illustrate the use of a locking system according to the invention in a Schiebefenster- and / or sliding door system according to the invention.

An inventive locking system is in the following description with the reference numeral 1 Provided. The locking system 1 is generally designed to block a removal of two wings of a sliding window and / or sliding door system in a direction transverse to the planar extension of the wing, in particular vertical locking direction. This is indicated by the locking system 1 a first locking part 3 like a male locking part, and a second locking part 5 , like a female locking part, on. The first locking part 3 has a substantially flat, elongated mounting surface 7 to attach to a wing 103 ( 13 to 15b) a sliding window and / or sliding door system 100 ( 13 to 15b) on. The mounting surface 7 is a continuous, substantially continuous surface, that is, except for passage openings 9 such as holes or millings that extend completely through the first locking part 3 from one of the mounting surface 7 opposite top 11 up to the mounting surface 7 extend through. The mounting surface 7 essentially represents the bottom 13 a tongue bearer 15 of the first locking part 3 dar. The tongue bearer 15 is designed as a flat, elongated plate, in particular mounting plate, preferably with a wall thickness in the range of 2 mm to 3 mm. The bottom 13 of the tongue bearer 15 has in plan view a substantially rectangular basic shape, two of a long edge 17 assigned corners 19 are rounded. For example, has the long edge 17 a length in the range of 110 mm to 130 mm. From the tongue bearer 15 out two extend tongues 21 , in particular locking tongues. In the exemplary embodiment according to 1 is the first locking part 3 made of one piece, wherein the material is preferably metal. However, it is also conceivable that the tongues 21 on the tongue bearer 15 attached, for example screwed, are. The identically trained tongues 21 extend from the long edge 17 from and are arranged at a distance to each other. The distance is in the direction of the long edge 17 to eat. This direction is referred to below as the transverse direction Q designated. An average distance here is for example 25 mm. An average tongue width, ie an extension of the tongue in the transverse direction Q , for example, is 20 mm. A tongue length, ie measured in the extension direction away from the tongue carrier 15 , is for example in the range of 20 mm to 30 mm. Each of the tongues 21 forms a locking surface on an associated tongue underside 23 , Each locking surface 23 is a substantially flat, in plan view, substantially rectangular surface, wherein on the tongue carrier 15 groundbreaking end of the locking surfaces 23 two associated corners to form inlet radii 24 are rounded. The mounting surface 7 and the locking surfaces 23 are substantially oriented parallel to each other, which is essentially to be understood that certain manufacturing tolerances are taken into account. By this arrangement of the mounting surface 7 and the locking surfaces 23 may be a flat shape of the second locking part 3 be achieved. Flat means that a small dimension or extent in one to the transverse direction Q vertical locking direction R is present. For example, has the second locking part 3 a dimension in the locking direction R ie from the mounting surface 7 out to one of the locking surfaces 23 opposite tongue top 25 measured in locking direction R , of 9 mm. The third direction is the displacement direction below V introduced to the transverse direction Q and to the locking direction R transverse, in particular perpendicular, oriented. The extension direction of the tongues 21 accordingly corresponds to the direction of displacement V , the direction of displacement V is further defined as the direction in which the first wing 103 and the second wing 105 be moved relative to each other.

The second locking part 5 has a base 29 , which is formed for example as a flat, elongated plate, in particular mounting plate, with an upper side 31 on. For example, there is a width of the top 31 measured in the transverse direction Q in the range of 100 mm to 115 mm and a length measured in the direction of displacement V in the range of 20 mm to 30 mm. The top 31 is essentially continuous, ie except for example three through holes 33 used for fastening the second locking part 5 serve. The passage openings 33 may be formed as countersunk holes and / or for example milled or drilled. From a bottom 35 the base 29 from at least two, or three extend in 1 and 2 , Feet 37 , In the illustrated exemplary embodiments are all feet 37 identically formed. The second locking part 5 is preferably made of one piece, in particular metal is used as material. However, it is also possible that the feet 37 to the base 29 bolted or otherwise attached thereto. The feet 37 are at the bottom 35 the base 29 arranged at a distance from each other, wherein a distance between two adjacent feet 37 is the same and, for example, in the range of 30 mm to 40 mm. When running in 1 . 2 are three feet 37 provided, with the two outer feet 37 on the edges 30 the base 29 in the transverse direction Q are arranged and vorsprungsfrei in the base 29 pass. At a bottom of the feet 37 each of these forms a mounting surface 27 which is formed as a substantially flat, in plan view, the cartridge-shaped surface and for securing the second locking part 5 at another wing 105 ( 13 to 15b) the sliding window and / or sliding door system 100 serves. Two adjacent feet 37 define a tongue recording 47 , in particular locking or Einfahrasche, wherein the feet 37 and between your feet 37 on the bottom 35 the base 29 extending section 49 (for example 4b) bridge-like the tongue pickup 47 surround. Every foot 37 has a tine 39 which is essentially in the direction of displacement V from the respective foot 37 extends out and over the base 29 protrudes. One of the tongue recording 47 facing tine inside 41 , one of the tongue recording 47 opposite tine outside 42 and one on the tine inside 41 subsequent tine top 43 are formed obliquely, that is not parallel to the direction of displacement V running so that the tine inside 41 , the tines outside 42 and the tine top 43 in a common tine tip 45 lead. Accordingly, a tine cross section increases towards the tine tip 45 for example, continuously. The tine inside 41 and also the tine outside 42 act as inlet radii. It is clear that the tine inside 41 and the tine outside 42 of in 1 pictured middle tine 39 adjacent tongue shots 47 are assigned and thus as the inlet radius of the respective tongue recording 47 serve. This means a prong 39 two inlet radii 41 . 42 for two adjacent tongue recordings 47 provides. In general, the inlet radii ensure 41 . 42 a safe retraction of the tongues 21 in the corresponding tongue recordings 47 even with not quite aligned tongues or tongue recordings. The section 49 that is between two adjacent feet 37 extending part of the base plate base 35 that the appropriate tongue recording 47 in a locking direction R limited, forms a locking surface 51 of the second locking part 5 , At the in 1 . 2 illustrated embodiment of the locking system 1 owns the second locking part 5 therefore two locking surfaces 51 , The obliquely formed tine tops 43 work as run-on surfaces, so in the closed state of the sliding window and / or sliding door system 100 a force due to the locking engagement between the two locking parts 3 . 5 especially gradually.

According to the invention, the first locking part 3 and the second locking part 5 configured to pass via a linear movement relative to each other in a locking engagement. The direction of linear motion is in 1 through the direction of displacement V indicated, with certain deviations from a purely rectilinear to the direction of displacement V parallel linear movement direction are allowed. In the locking engagement overlap or overlap locking surfaces 51 of the second locking part 5 with associated locking surfaces 23 of the first locking part 3 in a direction of linear movement, or shift direction V , vertical locking direction R , The locking surfaces 51 of the second locking part 5 and the locking surfaces 23 of the first locking part 3 are therefore in the locking direction R oriented opposite, so that they point towards each other when retracting into the locking engagement. The retraction takes place such that an overlapping or overlapping area of the associated locking surfaces 23 . 51 continuously increases up to a maximum value which is reached in a lock end position. As already indicated, the parallel arrangement allows the mounting surface 7 and the locking surfaces 23 of the first locking part 3 one in the locking direction R measured flat dimension. The same applies to the second locking part 5 in which the mounting surfaces 27 and the locking surfaces 41 are also oriented parallel to each other to achieve a flat overall dimension. It is also for example in the 1 . 2 to recognize that the linear movement direction, ie the direction of displacement V substantially parallel to the locking surfaces 23 . 51 and the mounting surfaces 7 . 27 is oriented. This then results in the overlap or overlap of the locking surfaces when entering the locking engagement 23 . 51 ,

In a development of the locking system according to the invention 1 are all locking surfaces 23 of the first locking part 3 and all locking surfaces 51 of the second locking part 5 oriented parallel to each other. This enhances the effect of a generally flat overall dimension of the locking system 1 so that, for example, an overall dimension may be less than 15mm. The locking system 1 can therefore also in places, for example, in spaces between two wings 103 . 105 a sliding window and / or sliding door system 100 , are used, which offer little space or space. Furthermore, the flat, parallel mounting surfaces provide 7 or. 27 a flexible and easy way to attach the respective locking part 3 . 5 for example, on a wing 103 . 105 the sliding window and / or sliding door system 100 ,

In particular in 2 you can see that the two tongues 21 of the first locking part 3 so with respect to the two tongue recordings 47 are dimensioned that the tongues 21 in the tongue shots 47 can retract to the ingestion of the locking engagement. For example, a locking end position is provided, which is a further relative displacement of the first locking part 3 with respect to the second locking part 5 prevented. When retracting a tongue 21 in a corresponding tongue recording 47 For example, the overlap area increases continuously to an overlap maximum, which is, for example, 450 mm ² and is achieved in the lock end position. With increasing overlap of the locking surfaces 23 . 51 increases the burden on the locking system 1 is able to in locking direction R to transfer or record. This means that the maximum power transmission is achieved in the lock end position. For example, the locking system 1 designed in the locking engagement, ie in particular in the Verriegelendposition, a load in the locking direction R of at least 3 kN, preferably at least 4 kN, preferably at least 5 kN, at least 7 kN or preferably at least 10 kN. In other words, the locking system 1 to be able to with an external load or force this load or force of the one locking part 3 . 5 on the other locking part 5 . 3 to transfer, and vice versa. Furthermore, in particular in 2 to realize that the tines 39 when retracting into the locking engagement the tongue carrier 15 underrun such that in the Verriegelendendstellung the first locking part 3 and the second locking part 5 are braced against each other. This means that when taking the locking engagement, so with a relative movement in the direction of displacement V by going under the tines 39 a relative movement component in the locking direction R arises, which causes the locking surfaces 23 . 51 be moved towards each other. In an exemplary embodiment, the locking surfaces are 23 . 51 in the Verriegelend position in contact, ie they are at least partially on each other. Furthermore, jammed in the Verriegelendendposition, for example, in 2 is indicated, the locking surfaces 23 . 51 as well as the tine top 43 with the tongue carrier top 11 against each other to the recordable load in the locking direction R continue to increase.

In the execution according to 3a . 3b has the first locking part according to the invention 3 only one tongue 21 this being otherwise essentially the same as the execution of the first locking part 3 to 1 . 2 is trained. Referring to the top 11 according to 3a has the tongue 21 in the area of the inlet radii 24 an inlet chamois 53 to assist in a secure capture of the locking engagement. For example, one dimension is the break-in phase 53 2 mm x 30 ° (width x angle), with other dimensions permitting support for the engagement of the locking engagement. In addition to the inlet radii 24 owns the tongue 21 also inlet radii 55 at a transition of the tongue 21 in the tongue bearer 15 , That is, the inlet radii 55 are on the sides of the tongue 21 with respect to the transverse direction Q , where the inlet radii 55 opposite to the inlet radii 24 are arched. For example, the inlet radii 24 arched outwards and the inlet radii 55 arched inwards. The passage openings 9 are realized, for example, as recessed through holes, with one each reduction 57 for example, conical or plan may be formed. The two sunk through holes 9 are immediately adjacent to the tongue 21 in the tongue bearer 15 and preferably in the direction of displacement V centered on the tongue carrier 15 arranged. On the bottom 13 of the first locking part 3 has the tongue 21 especially in the area of the inlet radii 24 So at one in the direction of displacement V measured front end of the tongue 21 , a starting or centering slope 59 on, in addition to a centering function and a safe retraction in the locking intervention should support. In other words, has the locking surface 23 the tongue 21 a starting slope 59 , wherein a Anfahrschrägenwinkel preferably in the range of 5 ° to 45 °, in particular 30 °, may be. The same from the bottom 13 Her visible inlet radii 55 are also intended to prevent a corner crack.

In 4a . 4b is a second locking part according to the invention 5 shown, which preferably together with the first locking part 3 to 3a . 3b is used. According to the formation of the first locking part 3 with only one tongue 21 is at the second locking part 5 only a tongue recording 47 ie only two feet 37 , intended. In 4a it can be seen that the passage openings 33 from the top 31 are realized, for example, as countersunk through holes, each with a reduction 61 for example, conical or plan may be formed. The respective obliquely formed tine inside 41 the tines 39 serves as entry radius and assists in taking the locking engagement by the tine inside 41 when approaching through a tongue 21 This safely in the tongue recording 47 leads. On the bottom 35 As shown in FIG. As the second locking part 5 in a transitional area between feet 37 or tines 39 a radius 63 to avoid a corner crack on. The tongue recording 47 has one with the approach slope 59 cooperating ramp 65 on, to a tilting with the tongue 21 to avoid and to facilitate the insertion of the locking engagement. For example, a ramp angle is in the range of 5 ° to 45 °, in particular, the ramp angle is 30 °. To assist the assembly of the second locking part 5 for example, on a wing 105 can at a bottom 35 the feet 37 a positioning aid 67 be provided as elevated, in the transverse direction Q may be formed extending web. For example, there is a width of the positioning aid 67 So an extension in the direction of displacement V , in the range of 5 mm to 10 mm. One in the direction of displacement V measured overall dimension of the second locking part 5 from the tip of the tongue 45 up to a long edge 32 the base 29 For example, it is in the range of 25 mm to 50 mm, with a dimension of about 35 mm being preferred.

Referring to 5 . 6 are two alternative embodiments of an embodiment of the first locking part 3 with two tongues 21 , as in 1 . 2 shown, wherein the embodiments only by the shape of the locking surfaces 23 differ. While in 5 the locking surfaces 23 are realized as substantially flat, smooth surfaces, so that a uniform retraction of the tongues 21 in corresponding tongue recordings 47 is ensured at constant frictional resistance, have the locking surfaces 23 according to 6 a kind of profiling or ribbing, preferably two transverse webs 69 , The crossbars 69 extend substantially in the transverse direction Q over the entire width of the locking surfaces 23 and stand by these in the locking direction R , preferably 1 mm, 2 mm or 3 mm, forth. In the 5 . 6 can also be seen that the starting slope 59 in particular over the same distance as the transverse webs 69 over the locking surfaces 23 can stand out.

In 8th . 9 are two alternative embodiments of an embodiment of the second locking part 5 with two tongue shots 47 , as in 1 . 2 , which are preferably used in combination with the embodiments according to FIG 5 or. 6 come used, with the embodiments only by the shape of the locking surfaces 51 differ. In the execution according to 8th are the locking surfaces 51 essentially flat and smooth, especially around with the smooth surfaces of the locking surfaces 23 to 5 co. As in 9 can be seen, have the locking surfaces 51 a kind of profiling or ribbing, preferably three transverse grooves 71 which are essentially transversal Q over the entire width of the locking surfaces 51 extend. The transverse grooves 71 are designed to with the crossbars 69 cooperate in such a way that when retracting the tongues 21 in the tongue shots 47 the crossbars 69 successively in successive transverse grooves 71 intervention. A distance between two adjacent transverse grooves 71 in the direction of displacement V is at a distance of two adjacent transverse webs 69 matched, wherein a dimension of the transverse groove 71 in the direction of displacement V is greater than a dimension of the crosspiece 69 , The crossbars 69 can therefore into the transverse grooves 71 snap in to the resistance in the direction of displacement V Increase or reduce abruptly when merging and expanding. This makes it possible, inter alia, a haptic and / or acoustic feedback on the progress of retraction of the tongue 21 in the tongue recording 47 to obtain. In both versions according to 8th . 9 is at a rear end of each tongue pickup 47 one from the plate base 35 protruding end stop 73 provided on which the tongue 21 may be used to limit the collision.

The side view of the first locking part 3 according to 7 clarifies that its mounting surface 7 and its locking surfaces 23 oriented parallel to each other and facing in the same direction. The first locking part 3 is stepped in the side view. This means that the tongues 21 in locking direction R offset to the tongue bearer 15 are arranged. Consequently, there are also the mounting surface 7 and the locking surfaces 23 at a different height in the locking direction R , The locking surfaces 23 In addition, not from the entire tongue bottom 13 formed, but exclusively by the in 7 shown horizontally, from the approach slope 59 up to a centering stop 75 extending section. For example, there is a length of the locking surfaces 23 in the direction of displacement V in the range of 15 mm to 30 mm. The centering stop 75 go flush in one's tongue 21 with the tongue bearer 15 connecting connection area 77 over. The tongue 21 covers or overlaps the tongue carrier 15 by a few millimeters, for example in the range of 3 mm to 10 mm (overlap section 79 ). The overlap section 79 opens on the locking part top 11 in the tongue bearer 15 ,

From the side view of the second locking part 5 according to 10 it can be seen that in the area of the top 31 the base 29 an overall dimension in the locking direction R is substantially constant, and preferably in the range of 5mm to 20mm, with a dimension of about 9mm being preferred. Only in the area of the locking direction R downwardly projecting positioning aid 67 the dimension is larger by a few millimeters, in particular 1 mm, 2 mm or 3 mm. At the point where the foot 37 in the tines 39 goes over, takes the dimension due to the obliquely formed tine top 43 towards the tip of the tine 45 continuously off.

In 11a . 11b or. 12a . 12b are alternative versions of the first locking part 3 or the second locking part 5 essentially different from the previous embodiments only in that three tongues 21 or three tongue recordings 47 are provided and comb-like from the tongue carrier 15 extend away. It can be seen that per tongue 21 two through holes 9 immediately adjacent to this in the tongue bearer 15 are introduced. Furthermore, those are also in the base 29 introduced through holes 33 arranged so that each one passage opening 33 one of the evenly along the extension of the base 29 in the transverse direction Q distributed feet 37 assigned. This means that each have a through hole 33 by a foot 37 extends through. As can already be seen in the previous figures, stands the tongue bearer 15 in the transverse direction Q over the respective outer tongue 21 around a border section 81 over. In other words, the tongue bearer points 15 in the edge section 81 no tongue 21 on.

Referring to 13 to 15b is the use of a particular trained according to one of the previous embodiments locking system 1 in a Schiebefenster- and / or sliding door system 100 , or in a Hebeschiebefenster- and / or lift and slide door system described. 13 shows a perspective sectional view of the sliding window and / or sliding door system 100 with mounted locking system 1 , The sliding window and / or sliding door system 100 to 13 has a movable sliding sash 103 with a profile frame 107 on. In addition, another wing 105 , which can also be designed either as a sliding leaf or as a fixed wing, with a profile frame 109 intended. Both profile frames 107 . 109 consist of, in particular, paired vertically upright vertical beams and horizontal beams. In 13 are a vertical struts 111 of the sliding sash 103 as well as a vertical struts 113 the further wing 105 , hereafter referred to as passive leaf. The wings 103 . 105 are doing in the locking direction R arranged offset from one another. The sliding sash 103 is for opening and / or closing the sliding window and / or sliding door system 100 translational in the direction of displacement V displaceable, so that in a closed position of the sliding window and / or sliding door system 100 the vertical spar 111 of the sliding sash 103 and the vertical spar 113 of the passive leaf 105 in locking direction R overlap or overlap, as in 13 is shown. In this case, the vertical beams 111 . 113 each a fitting groove 115 . 117 for receiving a fitting (not shown) on a in the direction of displacement V oriented side surface of the respective vertical spar 111 . 113 on. Furthermore, one of the fitting groove 115 . 117 diametrically opposite side surface 119 . 121 designed to be a glass, such as an insulating glass, the sliding window and / or sliding door system 100 take. At the facing Vertikalholminnenflächen 127 or. 129 is each a sealing strip 123 or. 125 for receiving a respective seal 124 or. 126 attached, wherein in the closed state, the sealing strip 123 with the seal 126 in contact device, or the sealing strip 125 with the seal 124 to be isolated from external influences such as noise and / or wind or rain. In an exemplary embodiment, the locking system is 1 mounted such that the first locking part 3 on the vertical spar surface 127 of the sliding sash 103 and the second locking part 105 on one of the vertical spar surface 127 facing inner surface 131 the sealing strip 125 is mounted. According to 13 are the vertical Holminnennenflächen 127 . 129 and the sealing strip inner surface 131 aligned parallel to each other. The locking system 1 is designed to be a removal of the wings 103 . 105 in locking direction R to prevent. The two locking parts 3 . 5 are coordinated with each other and in particular so with respect to each other at the corresponding vertical beams 111 . 113 positioned them when moving the sliding sash 103 in the closed state get together in a locking engagement, as in 13 is indicated. In 13 is an embodiment of the locking system 1 with two tongues 21 or two tongue recordings 47 as shown in particular in relation to the 1 . 2 and 5 to 10, wherein the tongues 21 essentially completely into the corresponding tongue receptacles 47 retracted to produce the locking engagement. This means that the structure as well as the arrangement of the two locking parts 3 . 5 is matched to one another such that a blocking of a removal of the wings 103 . 105 in the locking direction R due to the locking engagement. When loading occurs in the locking direction R For example, due to gusts of wind or by human force in break-in attempts, is by the locking engagement between the two locking parts 3 . 5 a removal of the wings 103 . 105 in locking direction R prevented. Advantageously, the two locking parts wedge or jam 3 . 5 between respective lifting point pairs, wherein a lifting point pair by the break-in phase 53 the top 11 the tongues 21 and the sealing strip inner surface 131 and another stop point pair through the ramp 65 on the bottom 35 of the second locking part 5 as well as the connection area 77 of the first locking part 3 is formed.

According to 14a to 15b is the sliding window and / or sliding door system 100 as lift-and-slide window and / or lift-and-slide door system 150 , in the following Lifting Sliding System 150 called, formed, wherein the same components are provided with the same reference numeral. A lifting slide system 150 differs from the sliding window and / or sliding door system 100 essentially in that when moving the sliding leaf, which now lift sliding wing 153 is called, in its closed position or from its closed position, this lowered or raised. This is the lifting slide wing 153 provided with a lifting slide device (not shown), which is usually integrated in the respective profile frame. While 14a . 14b the closed position of the lifting slide wing 153 show in its lowered position is in 15a . 15b the lifting slide wing 153 in its raised, but not in the direction of displacement V shifted, position shown. It can be seen that the respective sectional views 14b . 15b which the locking engagement between the two locking parts 3 . 5 in the assembled state with a lift-and-slide system 150 represent and along the lines A - A and B - B are to be understood to be identical. This means that in the locking engagement both in the raised and in the lowered position of the lifting slide wing 153 a locking engagement results, which is a removal of the wings 153 . 105 in locking direction R prevented. It is clear that the locking parts 3 . 5 in 14a or. 15a only schematically and by means of a respective graphic break-up 155 . 157 are shown. In the graphic departure 155 in 14a grab the tongue 21 approximately in the center of the tongue holder 47 during the locking procedure. In the locking engagement according to FIG. 15a, which is triggered by the graphical break-up 157 is clarified, is the lifting slide wing 153 together with the first locking part 3 in the transverse direction Q up into the raised position of the lift gate wing 153 drove, so the tongue 21 of the first locking part 3 so within the tongue recording 47 of the second locking part 5 in the transverse direction Q moved up that tongue 21 with the upper foot 37 in attack. In this respect, the sliding movement amplitude limits a relative movement of the two locking parts, or the two adjacent wings, in the transverse direction Q , The locking engagement thus leaves a lifting movement amplitude of at least 3 mm, preferably at least 5 mm, in particular at least 8 mm between the locking parts 3 . 5 in a transverse direction Q to. The lifting movement amplitude is at a height of a door threshold (not shown) of the lifting and sliding system 150 It should be remembered that the lower the height of the threshold, the lower the permitted lift amplitude. The lifting sliding system according to the invention 150 with a locking system according to the invention 1 So is designed such that an anti-burglar or a safeguard against increased wind loads while ensuring the lift-shift function is provided. In case of burglary attempts are made to lift the lift gate 153 to lift over the running rail of the door sill and then the lifting slide wing 153 from the passive wing 105 press away, using various tools, such as a crowbar, that in the space of the vertical beams 111 . 113 inserted and used as a kind of lever to further spread the gap to create a passage for a person. The lifting movement amplitude of the locking system according to the invention 1 is determined such that the lifting of the lifting slide wing 153 is just still guaranteed, however, a further lifting on the raised displacement position of the lifting slide wing 153 is no longer possible. Namely, the lifting movement amplitude becomes by the locking engagement between the two locking parts 3 . 5 realized, with the tongue 21 within the tongue socket 47 in the transverse direction Q Can be moved until the tongue 21 to an assigned foot 37 strikes. The fuse in the locking direction R is also due to the locking engagement between the two locking parts 3 . 5 realized, namely by the fact that when a load occurs in the locking direction R the two locking parts 3 . 5 tense against each other, especially the tongue 21 within the tongue socket 47 jammed. In this way it is possible loads in the locking direction R in the amount of at least 3 kN, preferably 4 kN, preferably 5 kN, preferably 6 kN, preferably 7 kN, or even 10 kN to transfer. Furthermore, it is clear that with increasing surface extension of the wing, in particular the lifting slide wing 153 , the attack surface for wind loads increases from the outside. For this reason, the requirement for the recordable load in the locking direction also increases R with increasing size of lift gate wing 153 strong too. On the lift slide wing 153 acting wind loads cause a bending or curvature of the wings between the vertical beams, so that on the vertical spar 111 in the middle closure area very high loads in the locking direction R occur, which is a mutually removing the lift slide wing 153 and the passive wing 105 cause. The locking system 1 is able to absorb these forces and remove the wings 153 . 105 prevent each other. Because the profile frame 107 . 109 usually made of plastic, such as PVC, are used for mounting the locking parts 3 . 5 on the vertical beams 111 . 113 stiffeners 159 , in particular of metal or steel, preferably aluminum or preferably polyamide core, used to increase the stability. The assembly takes place, for example, by means of screws (not shown) along the screwed connections 161 ( 14b . 15b) , It is clear that such stiffeners 159 also with sliding window and / or sliding door systems 100 be used.

The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
