Parallel sliding system

Abstract

The invention relates to a parallel sliding system, in particular a sliding-tilting system, comprising a sash, in particular a window or door sash, which can be moved horizontally from a closed position, in which the sash closes an opening, in particular a window or door opening, into a sliding position, in which the sash can be moved parallel to the opening into an open position that exposes the opening, and at least one slider which, when the sash is moved horizontally from the sliding position back into the closed position, is moved vertically relative to the sash in order to seal at least a gap between the sash and a horizontal mullion of a frame profile surrounding the sash in the closed position.

Description

[0001] The invention relates to a parallel sliding system, in particular a storage sliding system.

[0002] Parallel sliding systems are used particularly for windows and doors. These generally comprise fixed glazing, particularly fixed window glazing or fixed door glazing, and a sash, particularly a window sash or door sash, which can be moved from a closed position, in which the sash closes an opening, particularly a window opening or door opening, to a sliding position, in which the sash can be moved parallel to the opening into an open position that exposes the opening. In the sliding position, the sashes are generally guided in one or two rails, particularly an upper and a lower rail. Various systems are known for moving the sash from the sliding position to the closed position and vice versa.

[0003] One system is the parallel tilt and slide system (PSK system). In this system, the sash is first tilted from the closed position and then moved away from the opening via carriages and rods. Another system is the parallel stop and slide system (PAS system), in which the sash is moved into the sliding position away from the opening without a prior tilting movement, parallel to the opening via carriages and rods. The PSK system and the PAS system have in common that in the closed position they are essentially arranged in the same plane as the fixed glazing. This has the advantage that the facing vertical struts of the sash and the fixed glazing are butted up to one another in the closed position, creating a wide contact surface along the facing end faces of the vertical struts, on which two seals can be arranged that run around the sash in the sealed state.Typically, one of the circumferential seals is used as an inner seal (sealing the sash from the inside of the room) and one as an outer seal (sealing the sash from the outside of the room). By using two circumferential seals, parallel sliding systems can achieve a high degree of watertightness against driving rain. Furthermore, the circumferential inner seal allows the rebate area to be used for ventilation and drainage without risking the water and / or cold air entering the rebate area from entering the interior.

[0004] The disadvantage of the PSK and PAS systems is that, due to the aligned arrangement of the sash and fixed glazing in the closed position, they require a relatively large movement to move the sash from the closed position to the sliding position, typically between 60 mm and 80 mm. This makes the required mechanisms larger, more complex, more expensive, and, in particular, more prone to failure.

[0005] These problems are solved by lift-and-slide systems (HS systems) and tilt-and-slide systems (AS systems). The sash and the fixed glazing are offset from one another, even in the closed position, so that moving the sash from the closed position to the sliding position and vice versa only requires a movement of a few millimeters, usually between 5 mm and 7 mm. With HS systems, the sash is moved from the closed position to the sliding position by a vertical movement, particularly on a carriage. With AS systems, the offset from the closed position to the sliding position occurs by a horizontal movement, particularly a horizontal movement aligned orthogonally to the sash pane (hereinafter also referred to as the tilting movement).Due to the relatively small stopping movement, the mechanisms for moving the sash from the closed position to the sliding position and vice versa can be designed to be simpler, cheaper and, in particular, less prone to failure.

[0006] However, the offset arrangement of the sash to the fixed glazing, even in the closed position, creates challenges for sealing. The butt joint arrangement of the sash and the fixed glazing in PSK and PAS systems in the closed position creates overlap areas both between the outer sides of the sash and fixed glazing and between the inner sides of the sash and fixed glazing. This means that in the closed position a seal can be formed that runs around the inside of the sash, in particular an inner seal, and a seal that runs around the outside of the sash, in particular an outer seal. In contrast, with AS systems and HS systems, due to the offset arrangement of the sash and fixed glazing in the closed position, there is only one overlap area available: between the inside of the fixed glazing and the outside of the sash.Therefore, conventional AS and HS systems only have one seal surrounding the sash in the closed position. This is usually the outer seal. However, with only one seal, the previously described advantages of PSK and PAS systems regarding ventilation and drainage cannot be achieved.

[0007] A further problem, which occurs particularly with tilt-and-slide systems (AS systems), is that notches are provided in the sash profiles for the tilting movement, which allow the horizontal tilting movement from the closed position to the sliding position and vice versa. These notches result in a gap between the sash and the horizontal stiles of a frame profile that surrounds the sash in the closed position. Since the sashes of AS systems perform a purely horizontal tilting movement, the gap between the sash and the horizontal stile cannot be completely closed even in the closed position. This means that the rebate area between the sash and the frame profile is always in contact with the atmosphere of the interior, which is to be sealed off from the environment with the parallel sliding system.In systems that additionally utilize the rebate area for ventilation and drainage, i.e., systems where the rebate area is not completely sealed from the outside environment, this results in the interior space being connected to the outside via the rebate area, even in the closed position, which can lead to water ingress and heat loss. DE 86 03 749 U1 discloses an example of a parallel sliding system.

[0008] It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a parallel sliding system, in particular a storage sliding system, with which the tightness of the system, in particular the sealing of the inside of the room with respect to the outside of the room, is improved.

[0009] This problem is solved by the subject matter of independent claim 1.

[0010] The invention relates to a parallel sliding system, in particular a storage and sliding system. The parallel sliding system comprises a sash, in particular a window or door sash, which can be moved horizontally from a closed position, in which the sash closes an opening, in particular a window opening or door opening, into a sliding position, in which the sash can be moved parallel to the opening into an open position exposing the opening. The sash preferably has a pane, in particular a glass pane (hereinafter also referred to as glazing). Furthermore, the sash has, in particular, a sash profile surrounding the pane, with an upper and lower horizontal beam in the vertical direction, as well as an outer vertical beam, which faces the opening in the open position, and an inner vertical beam, which faces away from the opening in the open position.The parallel sliding system preferably further comprises fixed glazing, in particular fixed glazing, preferably fixed window glazing or fixed door glazing. The fixed glazing preferably comprises a pane, in particular a glass pane. The fixed glazing preferably comprises a fixed glazing profile surrounding the pane. The profile preferably comprises an upper and lower horizontal beam in the vertical direction, as well as an outer vertical beam facing away from the sash in the closed position, and an inner vertical beam facing the sash in the closed position. The outer and / or inner vertical beam can have a supporting structure to which a cover profile is attached.

[0011] Preferably, the panes of the sash and / or the fixed glazing each extend in a main plane of extension. Preferably, the respective main plane of extension of the pane of the sash and / or the fixed glazing is spanned by a vector oriented in the vertical direction and a vector oriented in the horizontal direction. Preferably, the vector oriented in the horizontal direction corresponds to a sliding direction in which the sash can be moved towards the open position. The main plane of extension is preferably understood to be the plane in which the pane extends. Preferably, the main plane of extension is the plane that is arranged centrally in the pane in the thickness direction of the pane.

[0012] Preferably, the sash is moved from the closed position into the sliding position in the direction of the normal to its main extension plane. The normal to the main extension plane of the sash can also be referred to as the retraction direction. In principle, the parallel sliding system according to the invention comprises PSK systems, PAS systems, and retractable sliding systems (AS systems), as long as these provide for horizontal displacement of the sash to move the sash from the closed position to the sliding position. However, the invention particularly preferably relates to a retractable sliding system. A retractable sliding system is characterized in particular in that the sash and the fixed glazing, in particular the main extension plane of the sash and the fixed glazing, are offset from one another in the closed position. In particular, the panes of the sash and the fixed glazing are spaced apart from one another in the retraction direction in the closed position.In particular, the distance between the panes in the tilting direction in the closed position is at least 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm or 60 mm. Preferably, the panes are spaced from one another in the closed position by sections of the inner vertical members of the sash and of the fixed glazing that face one another in the tilting direction. Preferably, the members of the sash frame and / or the fixed glazing frame each have an inner side facing the interior and an outer side facing the exterior (environment). Preferably, the inner side and the outer side extend substantially parallel to the main plane of extension of the respective pane. In particular, this essentially comprises a deviation from a perfectly parallel extension of + / - 30°, 25°, 20°, 15°, 10°, 5°, 3° or 1°.Preferably, each of the beams further comprises an end face that extends, in particular, between the inner side and the outer side in the storage direction. In addition to the storage direction, the end faces of the beams preferably extend in the vertical direction for vertical beams and preferably in the horizontal direction for horizontal beams.

[0013] Preferably, the inner vertical members of the pane and the fixed glazing overlap in the sliding direction in the closed position. Preferably, the inner vertical members overlap in the sliding direction over at least 30%, 40%, 50%, 60%, 70%, or 80% of one of the vertical members, in particular the larger vertical member, in the sliding direction.

[0014] Due to the offset arrangement of the sash and fixed glazing, the sash can be moved from the closed position to the sliding position with a relatively small movement in the retraction direction. The retraction-sliding system is preferably designed to move the sash through a retraction movement path of between 1 mm and 20 mm, preferably between 2 mm and 15 mm, particularly preferably between 3 mm and 10 mm. mm, preferably between 5 mm and 7 mm, from the closed position to the sliding position. Particularly preferably, the tilting-sliding system is designed so that the tilting movement occurs essentially exclusively in the horizontal direction, in particular in the tilting direction. Essentially means, in particular, that the previously described amplitude occurs at least 60%, 70%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% in the tilting direction, i.e., in the direction orthogonal to the main extension direction of the pane of the sash.

[0015] Preferably, the sash can be moved orthogonally to the closing direction in the sliding position. In particular, the sash can be moved parallel to the main plane of extension of the sash pane and / or the pane of the fixed glazing in the sliding position.

[0016] According to the invention, the parallel sliding system has at least one slider which, when the sash is moved horizontally from the sliding position back into the closed position, is moved vertically relative to the sash in order to sealably close at least one gap between the sash and a horizontal member of a frame profile surrounding the sash in the closed position. To enable the sash to be moved from the closed position into the sliding position, in particular in the stowed direction, a notch is provided in the horizontal members of the sash, particularly in stowed-sliding systems, which allows the sash to move relative to the horizontal members of the frame profile, in particular to rails arranged therein that guide the sash in the sliding position.However, in conventional sliding-and-tilting systems, this notch results in a gap remaining between the sash and the horizontal stile of the frame profile, even in the closed position. Since conventional sliding-and-tilting systems perform a purely horizontal movement when moving the sash from the closed position to the sliding position and back, this gap cannot be closed. As a result, conventional sliding-and-tilting systems cannot provide two circumferential seals, as otherwise the interior seal would be interrupted by the gap.By using a slider according to the invention, which is displaced in the vertical direction relative to the sash when the sash is displaced in the horizontal direction, this gap can be closed, whereby, as described in detail below, a second circumferential seal can be provided, in which an inner region of the inner seal is connected, in particular bridged, to an outer region of the inner seal by means of a bridging section.

[0017] According to the invention, the parallel sliding system comprises a guide firmly connected to the sash, which utilizes the horizontal movement of the sash between the closed position and the sliding position to displace the slider in the vertical direction. Preferably, the at least one guide and the at least one slider perform a horizontal movement and a vertical movement relative to one another in response to a movement of the sash between the closed position and the sliding position. Particularly preferably, the slider moves essentially exclusively in the vertical direction, and the guide essentially exclusively in the horizontal direction. "Essentially" is to be understood in particular as meaning that the movement amplitude of the sash or the guide is at least 70%, 80%, 90%, 95%, 98%, 99%, or 100% in the corresponding direction.

[0018] According to the invention, the guide has a receptacle for the slide, in which the slide is guided relative to the guide along a slide rail inclined relative to the horizontal. Preferably, the slide is guided in a form-fitting manner in the slide rail, in particular by means of a dovetail or T-slot connection. Preferably, the slide rail is inclined by at least 20°, 30°, 35°, or 40° relative to the horizontal, in particular in the direction of gravity. Preferably, the slide rail has a recess for receiving a guide lug, in particular in the form of a dovetail or T-shaped projection, of the slide.

[0019] The slider preferably has a slope complementary to the slider rail. The slope is preferably inclined at the same angle to the horizontal as the slider rail. The slider rail and / or the slope of the slider preferably extends downwards in the direction of gravity from a side of the recess facing the opening to a side of the recess facing away from the opening. Vertical sections adjoin the respective ends of the slider rail / slope of the slider, which preferably extend substantially in the vertical direction. "Substantially" is understood to mean a deviation of up to 30°, 20°, 10°, 5°, 3°, or 1° from the vertical.

[0020] Due to the inclination of the slide rail relative to the horizontal, the slide is forced into a vertical movement during a horizontal movement between the closed position and the sliding position. Preferably, the slide and guide are coordinated in such a way that the slide is moved vertically away from the respective horizontal beam of the frame profile during the movement from the closed position to the sliding position, in other words, toward the sash. When the sash moves from the sliding position back to the closed position, the slide is moved in the opposite direction, in particular away from the sash, toward the horizontal beam of the frame profile.

[0021] In order to ensure that the gap between the sash and the horizontal member of the frame profile is sealed in the closed position, the slider is preferably arranged in the closed position opposite a rail in which the sash is guided in the sliding position. The slider is preferably adapted to the contour of the rail in such a way that a gap existing between the slider and rail in the sliding position is sealed in the closed position. For this purpose, the slider preferably has at least one, preferably two, recesses which are designed to be complementary to projections, in particular guide projections, of the guide rail. As a result, in particular the projections of the rail can engage in the recesses of the slider in the closed position, so that the mutually facing end faces of the slider and rail can come into sealing contact with one another.

[0022] Alternatively or additionally, the parallel sliding system has at least one guide sealing means arranged on a side of the slider facing the opening, via which the guide, in the closed position, sealingly connects to a vertical strut of the frame profile. Preferably, the guide sealing means is arranged between the guide and the vertical strut of the frame profile in the closed position. In particular, the guide sealing means is pressed, in particular compressed, by the guide against the vertical strut of the frame profile in the closed position in order to provide sealing contact between the guide and the vertical strut of the frame profile. Preferably, the guide sealing means lies sealingly against the inner vertical strut of the fixed glazing profile in the closed position. In the preferred embodiment of the present invention, the inner vertical strut of the sash is formed by the inner vertical strut of the fixed glazing, in particular fixed glazing.In less preferred embodiments where there is no fixed glazing, for example, in embodiments where the sash is only movable relative to a wall, the vertical beam of the frame profile can also be formed by a frame profile that itself does not form the internal vertical beam of a fixed glazing. The guide sealant is preferably connected to the guide, in particular by a material bond, preferably by means of an adhesive. In particular, the guide can have a guide sealant receptacle into which the guide sealant can be inserted.In particular, the guide sealing means can be L-shaped, wherein a recess is provided in one of the sliding systems, which divides the guide sealing means into a receiving section, in particular an L-shaped receiving section, and a sealing section, in particular an I-shaped sealing section, to which the L-shaped section is in particular connected.

[0023] Furthermore, the parallel sliding system preferably has a slide sealing means arranged in a rebate area of the horizontal beam, with which the slide is in sealing contact in the closed position in order to seal the gap in the area of the vertical beam in the closed position. The slide sealing means is preferably arranged next to the guide rail in the horizontal direction, in particular in the setting-down direction, and in particular adjacent to it. In particular, the slide sealing means is arranged in a receptacle that is recessed relative to the guide rail in the direction of gravity. The slide sealing means preferably has an angular, in particular quadrangular, preferably rectangular, cross-section. The extension of the slide sealing means in the horizontal direction, in particular in the setting-down direction, is preferably greater, preferably at least twice, three times or four times as great as the vertical extension of the slide sealing means.Preferably, the slider sealing means is recessed in the horizontal member of the frame profile relative to the guide rail in such a way that the end face of the slider sealing means facing the slider is essentially at the same height in the vertical direction as the end face of the rail facing the slider. In this case, an offset between the end faces of up to 15 mm, 10 mm, 8 mm, 5 mm, 3 mm or 1 mm is preferably permissible. Particularly preferably, the end face of the slider sealing means facing the slider projects beyond the end face of the rail by the previously defined area. Preferably, the slider is adapted to the geometry and vertical extent of the slider sealing means and the rail in such a way that the slider is in sealing contact with both the guide rail and the slider sealing means when the sash is in the closed position.For this purpose, the slider preferably has a sliding body, which is responsible for the previously described translation of the horizontal movement of the sash into the vertical movement of the slider, and a slider tail adjoining the sliding body. In the closed position, the sliding body preferably forms a sealing connection with the guide rail, and the slider tail forms a sealing connection with the slider sealing means. The previously defined receptacle preferably extends completely through the guide in the sliding direction and has the previously described slider rail on one of its end faces. On a further end face, in particular on one of the previously described vertical sections, the guide preferably has a recess into which the slider tail preferably projects, preferably in the closed position and / or in the sliding position.

[0024] Particularly preferably, the slide, the rail, the slide seal, the guide, and the guide seal are coordinated with one another in such a way that, in the closed position, a sealing contact, in particular a continuous one, is formed from the area between the slide and the rail, through the area between the slide and the slide seal, to the area between the guide and the guide seal. In particular, the sealing contact runs essentially horizontally in the area of the rail and the slide seal and vertically in the area of the guide seal.

[0025] As previously described, the parallel sliding system preferably comprises at least one rail guiding the sash in the sliding position, with which the slider is in sealing contact in the closed position in order to seal the gap in the region of the rail in the closed position. Preferably, the at least one slider and the at least one rail are coordinated with one another in such a way that the rail essentially prevents movement of the slider in the horizontal direction, in which the sash can be displaced between the closed position and the sliding position. This can be ensured in particular by projections on the rail, which extend in particular in the vertical direction, which block movement of the slider in the horizontal direction.For example, the relative displacement between the slider and the guide along a slide rail inclined relative to the horizontal can be converted into a purely vertical movement of the slider and a purely horizontal movement of the guide, in particular together with the sash.

[0026] Preferably, the at least one slider is arranged in the region of the inner vertical spar of the sash profile. Particularly preferably, the at least one slider is arranged in the region of a front-end cover profile of the inner vertical spar, wherein the cover profile is attached to a support structure of the vertical spar. In particular, the guide is attached to the vertical spar, preferably as described above.

[0027] Particularly preferably, the guide is arranged in the vertical direction between the guide rail and the front-side cover profile of the vertical beam. Particularly preferably, the guide adjoins an end of the cover profile facing the rail in the vertical direction. In particular, the guide is designed to be flush with the front-side cover profile in such a way that an extension, in particular a planar extension, of the front-side cover profile is continued by the guide and, in particular, exclusively, interrupted by the previously described receptacle for the slider. Apart from the interruption caused by the receptacle for the slider, the guide preferably extends essentially to the horizontal beam opposite the guide, in particular to the previously described slider sealing means arranged in the rebate area of the horizontal beam.In this case, “essentially” is to be understood in particular as meaning that, in particular in the closed position, the distance between the end of the receptacle facing the horizontal beam, in particular the sliding sealing means arranged therein, and the horizontal beam, in particular the slide sealing means arranged therein, is a maximum of 20 mm, 15 mm, 10 mm, 5 mm, 3 mm or 1 mm. The slide is preferably designed to be complementary to the receptacle of the guide in such a way that the side of the slide extending parallel to the end face of the cover profile continues the planar extension of the cover profile and / or the guide in the region of the receptacle. In this case, “essentially” is to be understood in particular as an offset of a maximum of 20 mm, 15 mm, 10 mm, 5 mm or 3 mm between the end face of the slide and the end face of the guide and / or the cover profile.

[0028] The parallel sliding system preferably has at least one rail (guide rail), in particular an aluminum rail, that guides the sash in the sliding position. The slider can preferably be designed as a sealing body that, in the closed position, seals a gap between the sash and a horizontal member of a frame profile that surrounds the sash in the closed position, and in the sliding position forms a linear contact with the guide rail. It has been recognized that noise development, in particular whistling, squeaking, and grazing noises, when sliding the sash is caused primarily by contact between the sealing body, in particular the slider, and the guide rail.Surprisingly, it was discovered that this noise development can be significantly reduced without significantly impairing the sealing function of the sealing body by designing the contact between the sealing body, in particular the slide, and the guide rail in the sliding position as a linear contact. Noise development is reduced in particular by the fact that the linear contact reduces the noise-generating contact area between the sealing body, in particular the slide, and the guide rail compared to a flat contact.

[0029] Preferably, in the sliding position, the linear contact is the only contact between the at least one sealing body and the at least one guide rail. It should be understood that, particularly as a result of small movements and manufacturing tolerances, particularly during displacement of the sash in the sliding position, the linear contact between the sealing body and guide rail can be temporarily interrupted, temporarily become a surface contact, or temporarily further contacts can arise between the guide rail and the sealing body. However, particularly in the stationary state, in the sliding position, there should preferably be exclusive linear contact between the at least one sealing body and the at least one guide rail.In the embodiments described below and previously with two sealing bodies, in particular slides, and two guide rails, one, preferably exclusively one, line contact should preferably be formed in the sliding position between each pair consisting of sealing body and guide rail. It should be understood that the claimed line contact does not have to be a perfect line contact in the sense of a line of infinitesimally small points. Rather, the claimed line contact is to be understood in particular as a contact between two surfaces which, due to the shape and / or alignment of the surfaces relative to one another, runs exclusively along a line in which the two surfaces are tangent or intersect.For example, a line contact can be understood as a contact that occurs between two surfaces, at least one of which is inclined relative to the other, in particular between 1° and 7.5°, preferably between 1.5° and 5°, and / or at least one of which is curved. Alternatively or additionally, a line contact is preferably understood as a contact between two surfaces that is at least 5 times, preferably at least 10 times, particularly preferably at least 20 times, as large in a longitudinal direction as in a width direction orthogonal to the longitudinal direction and preferably extends in the width direction by at most 5 mm, 3 mm, 2 mm, 1 mm, or 0.5 mm.

[0030] Preferably, the sealing body and the guide rail engage with each other in the closed position via a tongue and groove system, wherein the line contact in the sliding position is formed between a groove and a tongue of the tongue and groove system, in particular wherein the groove is formed in the sealing body and the tongue is formed in the guide rail. Preferably, the guide rail has a horizontally extending running section on which rollers in particular can roll between the sash and guide rail, from which the tongue extends in the vertical direction. Preferably, the tongue extends, in particular in rod form, as a projection in the vertical direction and / or in the horizontal direction, in particular in the sliding direction, parallel to the guide rail, in particular over the entire extent of the guide rail in the horizontal direction, in particular in the sliding direction.The groove is preferably designed as a recess extending vertically into the sealing body and / or extends horizontally, in particular in the sliding direction, parallel to the rail, in particular over the entire extent of the sealing body in the horizontal direction, in particular in the sliding direction. The groove and tongue are preferably coordinated with one another in such a way that the groove is filled by the tongue protruding vertically in the closed position. As a result, the tongue can be sunk into the groove in the closed position so that the sealing body can come into sealing contact with the guide rail. The inventors have recognized that the linear contact in the sliding position, in particular by means of the embodiments described below, can be designed in such a way that the sealing contact is not impaired in the closed position.

[0031] Preferably, the line contact is provided by a relative inclination between at least one wall pair consisting of a groove wall and a tongue wall opposite the groove wall. The groove wall and the tongue wall preferably extend planar and are inclined by a maximum of 10° with respect to a vertical. Particularly preferably, one wall selected from the groove wall and the tongue wall extends substantially vertically and the other wall selected from the groove wall and tongue wall is inclined with respect to the vertical. For example, the groove wall can be inclined with respect to a vertical, with preferably the tongue wall running vertically, or the tongue wall can be inclined with respect to a vertical, with preferably the groove wall running vertically. The inclination is preferably between 0.5° and 10°, preferably between 1.0° and 7.5°, particularly preferably between 1.5° and 5°.Preferably, the inclination between the groove wall and the tongue wall is designed such that the groove wall and tongue wall converge vertically toward the guide rail and / or are spread vertically toward the sash. Particularly preferably, the groove wall and tongue wall extend toward each other in a V-shape, with the V opening toward the sash. The at least one groove wall and the at least one tongue wall are preferably each formed by one of two opposing, in particular planar and / or vertically extending, side walls.

[0032] Preferably, the inclination of the slide rail and the relative inclination between the at least one pair of walls are designed in the same direction, starting from a vertical. The inventors have recognized that with such an alignment of the inclinations in the same direction, noise development can be particularly reliably reduced and the smooth running of the sash when sliding in the sliding position can be improved or at least maintained. Without being bound to an explanation, this may be related to the fact that the relative inclination between the at least one pair of walls provides space for the slide in the direction in which it is pushed by the weight of the inclination of the slide guide, so that the risk of wedging or an increase in the contact surface between the slide and guide rail is reduced.It has been found to be particularly preferred, in the case of a slider and a guide rail which are arranged at the top in the direction of gravity with respect to the wing, to carry out the inclination of the slider rail and the relative inclination between the wall pair of slider and guide rail starting from a horizontal in the setting direction and / or in the case of a slider and a guide rail which are arranged at the bottom in the direction of gravity with respect to the wing, to carry out the inclination of the slider rail and the relative inclination between the wall pair of slider and guide rail starting from a horizontal in the direction opposite to the setting direction.

[0033] Preferably, the inclination between the groove wall and the tongue wall, particularly in the previously described embodiment, is between 1.0° and 10°, preferably between 2.0° and 7.5°, particularly preferably between 3° and 5°, most preferably 4°. The inventors have recognized that with such an inclination, in particular of 4°, on the one hand, the least possible contact is provided between the slider and the guide rail in the sliding position, thereby reducing noise generation, and at the same time, a sufficient form fit, in particular the smallest possible gap between the guide rail and the slider, is provided in the closed position in order to ensure the tightness between the slider and the guide rail.In this context, the inventors particularly recognized that increasing the inclination beyond 4° leads to a larger gap between the slide and the guide rail and thus to reduced sealing, while a smaller inclination, in turn, leads to increased noise generation. In this respect, an inclination of 4° has proven particularly preferable. However, a deviation in the inclination within the ranges described above has also led to acceptable results in terms of noise generation and sealing.

[0034] In a preferred embodiment of the previously described exemplary embodiment, a second relative inclination is formed between a second wall pair consisting of a second groove wall and a second tongue wall opposite the second groove wall, in particular wherein the second inclination is preferably formed in the other direction from a vertical, as is the inclination of the slide rail. Particularly preferably, the second inclination is formed in a different direction from a vertical, as is the previously described (first inclination) between the previously described (first) wall pair. In particular, the two relative inclinations are formed in such a way that they converge towards one another, in particular in the direction of gravity. In this embodiment, the second inclination is preferably between 0.5° and 7.5°, preferably between 1.0° and 5.0°, particularly preferably between 1.5° and 2.5°, most preferably 2°.The inventors realized that the second inclination can compensate for tolerances and movement of the sash during sliding, thus more reliably reducing noise and the risk of jamming. Similar to the first inclination, it has been found that a smaller inclination leads to higher noise and a higher risk of jamming, whereas a larger inclination leads to less airtightness in the closed position.

[0035] It has been found to be particularly preferred that the groove is formed in the slide and the (first) inclination, preferably the first and second inclinations, is / are introduced into one of the, in particular both, opposite side walls of the groove, wherein preferably in the case of a slide arranged at the top in the direction of gravity with respect to the wing, the first inclination, in particular the 4° inclination, is formed on the second side wall as viewed in the setting-down direction, and / or in the case of a slide arranged at the bottom in the direction of gravity with respect to the wing, the first inclination, in particular the 4° inclination, is formed on the first side wall as viewed in the setting-down direction, wherein in particular the second inclination, in particular the 2° inclination, is introduced on the correspondingly opposite side of the, in particular the respective, groove as viewed in the setting-down direction.In such an embodiment, the spring is preferably formed in the guide rail, wherein at least in the spring wall forming the line contact, preferably in all spring walls opposite one or both groove walls, no inclination relative to the vertical is formed, in other words these are vertically aligned.

[0037] The parallel sliding system preferably has two sliders which, when the sash is moved horizontally from the sliding position back into the closed position, are moved vertically relative to the sash in order to each seal a gap between the sash and the horizontal member of a frame profile which surrounds the sash in the closed position.

The inventive arrangement of the two circumferential seals between the mutually facing sides of the inner vertical member of the sash and the frame profile allows a second, inner circumferential seal (inner seal) to be provided in addition to the outer circumferential seal in tilt-and-slide systems and lift-and-slide systems. This allows the advantages of parallel tilt-and-slide systems and parallel tilt-and-slide systems with regard to sealing and thermal insulation to be achieved with lift-and-slide systems and tilt-and-slide systems.

[0040] Preferably, one of the two seals is an inner seal, which is attached in the region of the vertical member to a front cover profile of the, in particular, inner, vertical member.

Preferably, the two circumferential seals extend parallel to each other in the region of the vertical strut.Particularly preferably, the two circumferential seals are spaced apart from one another in the sliding direction in the overlapping region, in particular by at least 30%, 40%, 50%, 60%, 70% or 80% of the extension of one of the vertical beams in the sliding direction, in particular of the vertical beam with the greatest extension in the sliding direction.

[0043] Preferably, the previously described end-face cover profiles of the vertical beams are formed in two parts relative to a supporting structure of the vertical beam. Preferably, the cover profiles are connected to the supporting structure of the respective vertical beam in a form-fitting and / or force-fitting manner, in particular by means of a clip connection. Preferably, the sealing sides of the respective cover profile protrude relative to the supporting structures in the direction of the respective opposite vertical beam. Preferably, the vertical beams have receptacles for the respective seals or sealing sections.

Preferably, the overlap region extends along the horizontal members and along one, preferably the outer, vertical member of the sash.In the closed position, the inner seal is preferably in sealing contact with both the horizontal beam and the outer vertical beam of the sash as well as the frame profile, particularly in the overlap area.

[0045] Preferably, the inner seal in the area of the horizontal beams is in sealing contact with both the horizontal beams of the frame profile and the guide rails attached to them.

[0046] Preferably, the inner seal runs in sections on the inside and in sections on the outside of the wing, in particular in the area of the horizontal spars on the inside of the wing and / or in the area of the inner vertical spar on the outside of the wing and in the area of the outer vertical spar on the inside of the wing.

[0047] Preferably, the sections of the inner seal arranged on the side of the sash facing the opening and those arranged on the side of the sash facing away from the opening are connected to one another via bridging sections to form the circumferential seal.

[0048] The bridging section described above makes it possible to provide a circumferential seal that is positioned on the inside of the sash in the area of the horizontal members and the outer vertical member, and on the outside of the inner vertical member. This allows the vertical member of the frame profile opposite the inner vertical member of the sash to be used to create a sealed contact with the sash in this area.

[0053] In the following description of exemplary embodiments, a parallel sliding system according to the invention is generally designated by the reference numeral 1.

[0054] Figure 1 shows a front view of a parallel sliding system 1 according to the invention. The parallel sliding system 1 has a sash 3 and a fixed glazing 5. In the present case, the sash 3 is a window sash. The sash 3 is shown in a closed position in which the sash 3 closes an opening located in the plane of the drawing behind the sash 3, in the present case in the form of a window opening. The sash 3 has a handle 7, which can be operated to move the sash 3 horizontally into a sliding position ( Figures 2c and 3c), in which the sash 3 can be moved in the sliding direction S parallel to the opening and the fixed glazing 5 into an open position (not shown) in order to expose the opening. The sash 3 has a pane 9. The pane 9 is surrounded by a sash profile 11. The sash profile 11 has a lower horizontal bar 13 in the direction of gravity G and an upper horizontal bar 15. Furthermore, the sash 3 has two vertical bars 17, 19, namely an inner vertical bar 17, which faces away from the opening in the open position, and an outer vertical bar 19, which faces the opening in the open position. Likewise, the fixed glazing 5 has a pane 21 and a fixed glazing profile 23 surrounding the pane. The fixed glazing profile 23 has a lower horizontal bar 25 in the direction of gravity G and an upper horizontal bar 27 in the direction of gravity G.Furthermore, the fixed glazing profile 23 has an outer vertical beam 31, which faces away from the opening, and an inner vertical beam 29 (in . Fig. 1 not shown, see Fig. 4 ) which faces the opening. Furthermore, the parallel sliding system 1 has a frame profile 33 which, in the closed position, surrounds the sash 3. The frame profile 33 has an outer vertical beam 35. Furthermore, the frame profile 33 has a lower horizontal beam 25 in the direction of gravity G, which in this case also functions as the lower horizontal beam 25 of the fixed glazing profile 23, and an upper horizontal beam 27 in the direction of gravity G, which in this case also functions as the upper horizontal beam 27 of the fixed glazing profile 23. Furthermore, the frame profile 33 has an inner vertical beam 29 (in Fig. 1 not shown, see Fig. 4), which in this case also functions as the inner vertical beam 29 of the fixed glazing profile 23. The sash 3 and its pane 9 have a main extension plane spanned by the direction of gravity G and the sliding direction S. The fixed glazing 5 and its pane 21 also have a main extension plane spanned by the direction of gravity G and the sliding direction S.

[0055] Fig. 4 shows a sectional view along the line CC from Fig. 1 . Only the connecting pieces of the panes 9 and 21 are indicated. The outer vertical members 19, 31 and 35 are not shown. The main extension plane 37 of the sash 3 and the main extension plane 39 of the fixed glazing 5 are indicated by dashed lines. As can be seen from Fig. 4As can be seen, the main extension planes 37 and 39 are spaced apart from one another in the retraction direction A described in detail below. In particular, the inner vertical member 17 of the sash 3 and the inner vertical member 29 of the fixed glazing 5 or the frame profile 33 are arranged one behind the other in the retraction direction A. The vertical members 17 and 29 each have a supporting structure 41, 43 and a cover profile 45, 47 attached to the supporting structure 41, 43. The cover profiles 45, 47 are each connected to the supporting structure 41, 43 via clip connections 49. The cover profiles serve in particular as a screen and protection for the mechanisms of the parallel sliding system 1 attached to the supporting structures 41, 43. The cover profiles 45, 47 define one end face of the vertical members 17, 29. The interior of a building is in Fig. 4indicated by IR. The parallel sliding system 1 seals off the interior IR of the building from the exterior AR (environment). The outer sides of the vertical beams 17, 29 facing the exterior AR are marked with reference numerals 51 and 53. The inner sides of the vertical beams 17 and 29 facing the interior IR are marked with reference numerals 55 and 57. Fig. 4 the outer side 51 of the inner vertical beam 17 of the sash 3 and the inner side 57 of the vertical beam 29 of the fixed glazing 5 or the frame profile 33 are opposite each other in the closing direction A. The two seals provided according to one aspect of the invention, which run around in the closed position, are in Fig. 4with the reference numerals 59, 61. The seal marked with reference numeral 59 is the inner seal, which seals the parallel sliding system 1 from the interior IR. The seal marked with reference numeral 61 is the outer seal, which seals the parallel sliding system 1 from the exterior AR. As Fig. 4 can be removed, both the inner seal 59 and the outer seal 61 are arranged in the region of the vertical beam 17 of the wing 3 on the side of the wing 3 facing the opening, namely the outer side 51.

[0056] The Figures 11a and 11b show the execution of the Figure 1 area marked A of parallel sliding systems as known in the art. Figures 12a and 12b show according to the Figure 1 marked area B, as implemented in parallel sliding systems known from the state of the art.

[0057] In order to enable the sash 3 to be moved from the illustrated closed positions in the retraction direction A into the sliding position, notches 63, predominantly step-shaped notches 63, are provided at the upper and lower ends of the cover profile 45 in the direction of gravity G. These notches 63 allow the sash 3 to be moved into the sliding position without colliding with the guide rails 65, 67. A disadvantage of the notches 63, however, is that, particularly due to the pure retraction movement A in the retraction direction (i.e., due to a lack of retraction movement in the vertical direction), the closing of the gap 69, 71 between the cover profile 45 and the respective rail 65, 67 is not possible. As a result, the inner seal 59 in known systems is interrupted at least in the area of the notch 63, which impairs the atmosphere of the interior. IRis always connected via the notch 63 to the rebate area between sash 3 and frame profile 33 and is therefore also connected to the outside space AR in versions with drainage and ventilation realized via the rebate area.

[0058] To illustrate how the folding area 73 described above and below can be formed, Figure 13 , in which a rebate area 73 is shown between a lower horizontal beam 13 of a sash 3 and a lower horizontal beam 25 of a frame profile 33. An inner seal 59 seals the rebate area 73 against the interior IR so that the fold area 73 can be used for ventilation and drainage.

[0059] Figure 2a shows a perspective view of the Figure 1 shown area A and Figure 3a one on the in Figure 1shown area B of a parallel sliding system 1 according to the invention in the form of a storage sliding system 1. In each case a slider 75, 77 is provided which, when the sash 3 is moved horizontally in the storage direction A from the sliding position ( Figure 2c and Figure 3c ) back to the closed position ( Figure 2b and Figure 3b) is displaced relative to the sash in the vertical direction V in order to seal a gap 79, 81 between the sash 3 and the respective horizontal beam 13, 15. For this purpose, a guide 83, 85 is provided which is firmly connected to the sash 3 and which uses the horizontal movement, in particular in the closing direction A, of the sash 3 to displace the sliders 75, 77 in the vertical direction V. The respective slider 75, 77 and the respective guide 83, 85 carry out a horizontal movement and a vertical movement in response to a movement of the sash 3 between the closed position and the sliding position relative to one another, wherein the respective slider 75, 77 moves exclusively in the vertical direction V and the guide moves exclusively, in particular together with the sash 3, in the closing direction A.

[0060] In particular, the respective guide 83, 85 each has a receptacle 87, 89 for the respective slide 75, 77, in which the slide 75, 77 is guided relative to the respective guide 83, 85 along a slide rail 91, 93 inclined relative to the horizontal. The respective slide rail 91, 93 has a T-groove, over which a T-shaped projection 94, 95 is guided along the respective slide rail 91, 93. The slides 75, 77 preferably each have a slide body 97, 99, which, in the closed position, is in sealing contact with the respective guide rail 105, 107 described below. For this purpose, the slide body 97, 99 has two recesses 109, 111, 113, 115, which in the closed position are filled by projections 117, 119, 121, 123 of the respective guide rail 105, 107 projecting in the vertical direction.As a result, the respective projections 117, 119, 121, 123 can be countersunk into the corresponding recesses 109, 111, 113, 115 in the closed position, so that the respective slide 75, 77 can come into sealing contact with the respective rail 105, 107.

[0061] Furthermore, each of the slides 75, 77 has a slide sealing means section 101, 103, which can also be referred to as a slide tail, via which the respective slide 75, 77, in the closed position, is in sealing contact with a respective slide sealing means 125, 127 arranged in the corresponding horizontal beam 25, 27. As a result, in particular in the closed position, a continuous sealing contact with the respective rail 105, 107 and the adjoining slide sealing means 125, 127 can be provided via the respective slide 75, 77, in particular over the entire extension of the respective horizontal beam in the setting direction A. Furthermore, a guide sealing means 129, 131 is provided on each of the guides 83, 85, via which the respective guide 83, 85 is in sealing contact with the inner vertical bar 29 of the frame profile 33 or the fixed glazing profile 23 in the closed position.To accommodate the respective guide sealant 129, 131, the respective guide 83, 85 can have a guide sealant receptacle 133, 135. Complementary to the respective guide sealant receptacle 133, 135, the respective guide sealant 129, 131 can have a transition section 137, 139. In . Figure 9 In the example of guide sealing means 129, 131 shown, the transition section 137, 139 is L-shaped and adjoins an I-shaped main sealing section 141, 143.

[0062] The previously described design of the projections 117, 119, 121, 123 of the guide rails 105, 107 ensures, in particular, that the respective guide rail 105, 107 prevents a movement of the respective slider 75, 77 in the horizontal direction, in particular the retraction direction A, in which the wing 3 can be moved between the closed position and the sliding position. As can be seen in particular from the Figures 2b, 2c , 3b and 3cAs can be seen, the respective slider 75, 77 and its guide 83, 85 are attached in the area of the front cover profile 45 of the inner vertical strut 17 of the sash 3. The respective slider 75, 77 and the respective guide 83, 85 are coordinated with one another in such a way that when the sash is moved from the sliding position to the closed position, the two sliders 75, 77 are each moved in the vertical direction V away from the sash 3, in particular away from the cover profile 45 in the direction of the guide rail 105, 107 guiding the sash 3 in the sliding position, in particular until the respective sliders 75, 77 are in sealing contact with the respective guide rail 105, 107 and the respective sealing means 125, 127. At the same time, the movement opposite to the setting direction A creates a sealing contact between the respective guides 83, 85 and their guide sealing means 129, 131 with the inner vertical beam 29 of the frame profile 33 or.of the fixed glazing profile 23.

[0063] As previously described, in Figure 4 the aspect of the invention is shown, according to which at least two seals 59, 61 which run around in the closed position are arranged in the region of the vertical beam 17 of the wing 3 on a side of the wing 3 facing the opening. Figures 2b and 2c and 3b and 3c indicate how the circumferential inner seal 59 runs in the area of the horizontal beams 13, 15 of the wing 3, namely between the inner side 55 of the wing 3 and the inner side of the respective horizontal beam 25, 27.

[0064] In order to connect the inner and outer regions of the inner seal 59 to form a circumferential seal, the previously described sliders 75, 77 are used to each provide a bridging section of the seal along the lower horizontal beam 25 and the upper horizontal beam 27 of the fixed glazing frame 23 or the frame profile 33.

[0065] Figure 14 shows a side view of the Figure 3a shown area of the sliding door system with the sash in the closed position. Figure 14 solely by Figure 3b that a slider 77' with a modified recess 111', which is referred to below as groove 111', is used. The groove 111' has two opposing groove walls 145, 147. The groove wall 145 is inclined by 4° relative to a vertical. The inclination of the groove wall 145, starting from a vertical, is formed in the same direction as the inclination of the slide rail 93 of the guide 85. The groove wall 147 is inclined by 2° relative to a vertical. Figure 14The projection 121 of the guide rail 107 shown here will be referred to as the tongue 121, since the projection / tongue engages the groove 111' in the illustrated closed state according to a tongue-and-groove system. The tongue 121 has two opposing tongue walls 149, 151. The tongue walls 149, 151 extend in the vertical direction.

[0066] The left tongue wall 149 and the left groove wall 145 form a wall pair, between which a relative inclination of 4° is provided by the inclination of the groove wall 145 relative to the vertical by 4° and the vertical extension of the tongue wall 149. The inventors have recognized that this provides a linear contact between the slide 77' and the guide rail 107 in the sliding position, thereby reducing noise generation, and at the same time, a sufficient form fit, in particular a gap as small as possible between the guide rail 107 and the slide 77', is provided in the closed position to ensure the tightness between the slide 77' and the guide rail 107.

[0067] The right tongue wall 151 and the right groove wall 147 form a wall pair, between which a relative inclination of 2° is provided by the inclination of the groove wall 147 relative to the vertical by 2° and the vertical extension of the tongue wall 151. The inventors have recognized that this, on the one hand, provides linear contact between the slider 77' and the guide rail 107 in the sliding position, thereby reducing noise generation, and, at the same time, provides a sufficient form fit, in particular a gap as small as possible between the guide rail 107 and the slider 77', in the closed position to ensure the tightness between the slider 77' and the guide rail 107. The inventors have recognized that this inclination can compensate for tolerances and movements of the sash during sliding, so that noise generation and the risk of jamming can be reliably reduced.Similar to the 4° inclination described above, it has been found that a smaller inclination leads to higher noise levels and a higher risk of jamming, whereas a larger inclination leads to lower tightness in the closed position.

[0068] Figure 15 shows a modified guide rail 105' for use in the area of the lower horizontal beam of the frame profile according to the Figure 1 marked cutout A. The guide rail 105' is designed as an alternative to the Figure 2c The guide rail 105 shown in the figure is to be used in the area of the lower horizontal beam. For a better overview, Figure 2c on the same page as Figure 15shown again. The guide rail 105' differs from the guide rail 105 in particular by a modified projection 117'. The projection 117' and the recess 109 engage in the closed position according to a tongue and groove system, so that the projection 117' is referred to below as the tongue and the recess 109 as the groove. The tongue 117' has two opposing tongue walls 153, 155. The tongue wall 153 is inclined by 4° relative to a vertical. The inclination of the tongue wall 153, starting from a vertical, is formed in the same direction as the inclination of the slide rail 91 of the guide 83. The tongue wall 155 extends in the vertical direction. Figure 2c The groove 109 shown has two opposing groove walls 157, 159. The groove walls 157, 159 extend in the vertical direction.

[0069] The right tongue wall 153 and the right groove wall 157 form a wall pair, between which a relative inclination of 4° is provided by the inclination of the tongue wall 153 relative to the vertical by 4° and the vertical extension of the groove wall 157.
