Description

The present invention relates to a running rail for a lift-and-slide element, in particular for a lift-and-slide window or a lift-and-slide window, which comprises a wing and a roller arrangement, the runner defining a raceway on which the wing is movable by means of the roller arrangement, and wherein the wing in at least one position along its movability, in particular at least in a closed position, between a raised displacement position and a lowered fixing position is movable.

Such lifting slide elements find, for example, in the form of large patio doors or windows increasing popularity, but can also be used in the form of sliding walls for temporarily separating certain areas of a room. In general, in such lifting slide elements, the running rail is arranged below the wing, in particular on the ground, wherein a plurality of rollers arranged on the underside of the wing roll directly on the track of the lower running rail. The running rail can be designed here as a threshold or integrated into a frame. In principle, the roller arrangement could also be arranged on the upper side of the wing, wherein the rollers of the roller arrangement roll on a suspension rail. The running rail is arranged in such an embodiment above the wing.

In the lowered fixing position, the movability of the wing is blocked differently than in the raised displacement position, or at least considerably limited with respect to the movability in the displacement position. It can be provided be that the underside of the wing is seated in the lowered fixing position on the track, preferably immovable. In contrast, the underside of the wing may be spaced from the track by an air gap when the wing is in the raised travel position. Due to the formed air gap, the wing can be moved by means of the rollers when it is in the raised travel position. However, a seating of the underside of the wing on the track in the lowered fixing position is not mandatory. That is, the wing can be worn in principle in the lowered position by the rollers, wherein the fixing z. B. caused by a blockage of the rollers. Likewise, it is not mandatory that the air gap is recognizable as such from the outside. For example, the air gap could be labyrinthine.

In known slide rails for lift-and-slide elements, the slide rails themselves do not contribute to the adjustment, in particular raising or lowering, of the respective lift-and-slide element between the displacement position and the fixing position. Instead, a lifting mechanism is usually provided on the lifting slide element, which can be actuated for example by means of a provided on a frame of the wing handle, for example in the form of a pivot lever. To improve the comfort and an electrical operation can be provided. For this purpose, a motor may be provided on the wing, which can cooperate with the lifting mechanism to move the wing between the raised travel position and the lowered fixing position. However, such designs require relatively wide wing profiles in order to arrange the lifting mechanism as far as possible invisible or inconspicuous on or in the context of the wing. If the operation by means of an electric motor provided on the wing also requires power to be introduced into the wing, which is technically complex due to the movability of the wing.

It is an object of the invention to implement the movement of a lifting slide element, in particular a lifting slide element of the type mentioned between a raised displacement position and a lowered fixing position in a structurally simple way, which also allows narrow wing profiles and in particular at relatively low technical Effort can be automated.

The object is achieved in particular by a running rail with the features of claim 1. Preferred embodiments of the running rail emerge from the subclaims, the present description and the drawings.

A first step in the solution of the problem is to provide the means for moving the wing of the respective lifting slide element between the displacement position and the fixing position not on the lifting slide element, but on the running rail.

The running rail is advantageously designed for a lift-and-slide element, in particular for a lift-and-slide window or a lift-and-slide window, which comprises a wing and a roller arrangement and defines a raceway on which the wing can be moved by means of the roller arrangement. Such a method is used in particular to adjust the wing between a closed position and at least one open position. The method is carried out in particular in a plane which is defined by a planar extension of the wing.

According to the invention, the running rail has at least one lowering section, which is active between a flush position and a lowered position, in particular motor, in order to move the wing between a raised displacement position and a lowered fixing position, if the wing with a roller of the roller arrangement is on the lowering section. The wing can thus be moved by means of the running rail, namely by adjusting the at least one lowering section, between the raised displacement position and the lowered fixing position. Thus, advantageously no lifting mechanism needs to be provided on the wing.

The lowering section is a part of the running rail on which the wing with a roller of the roller arrangement can stand within its traversability along the track. For example, it can be provided that at least then a roller is on the lowering section when the wing is in the closed position. The flush position of the lowering section is in particular flush insofar as the lowering section is aligned in at least one traversing direction of the wing so flush or aligned to an adjacent portion of the track that a roller of the roller arrangement without substantial interference from the Absenkabschnitt to the adjacent section or vice versa can be moved, the roller rolls in particular on the running rail. Therefore, the flush position of the Absenkabschnitts the displacement position of the wing correspond, as it does not preclude a method of the wing.

In contrast, the lowering can be offset in the lowered position with respect to an adjacent portion of the track, so that a step is formed in the track. In the mounted state of the running rail, the lowering section is offset in the lowered position relative to the adjacent section, in particular downwards. If the wing with a roller of the roller assembly is on the lowering, an adjustment of the Absenkabschnitts in the lowered position thus have the consequence that also the wing is offset in a corresponding manner. As a result, the wing is then at least offset with this roller relative to the adjacent section, in particular with respect to the entire remaining career. To be in this state To be able to proceed, the roller would have to overcome the resulting stage. However, depending on the height of the step, in particular depending on the ratio of the height of the step to the radius of the respective roller, and / or depending on the weight of the wing, this may be impossible or only possible with difficulty. The wing can therefore be trapped with its roller in the lowered lowering of the track so to speak. Depending on the length of the Absenkabschnitts the wing while so to speak, at least be limited movable. Preferably, however, the wing is then blocked against any process, whether by the resulting step or the seating of the lowered wing on the track or a surrounding floor. In this respect, the lowered position of the lowering section can thus correspond to the fixing position of the wing.

An essential aspect of the invention is that the lowering section is active, that is, not merely passive, adjustable. By this is to be understood that it is possible in particular for a user of the respective lift-and-slide element to adjust the lowering section - be it manually and / or motor-driven, possibly automated - in principle as desired. The lowering section is thus not merely passive, e.g. adjusted by the weight of the wing and / or by the lowering always equal acting spring device. A passive adjustment is characterized in particular by the fact that the loading of the Absenkabschnitts takes place independently of a deliberately induced adjustment of the lowering device. In contrast, the active adjustability according to the invention can enable the lowering section, while the wing is mounted on the lowering section with a roller, to be adjusted to the flush position or to the lowered position, depending on the specification or actuation by a user.

For the active adjustment of the lowering section, in particular a separate drive device can be provided, as will be explained below. In this case, the lowering section can also be actively adjusted insofar as it means The drive device basically regardless of the position along the track, the wing is straight, can be adjusted, and in particular both in the direction of the flush position and in the direction of the lowered position. Preferably, the lowering section is adjustable by motor.

According to an advantageous embodiment, adjusting the lowering section between the flush position and the lowered position corresponds to a parallel displacement. In particular, the lowering section is offset parallel to the track. An active parallel offset may allow controlled movement, in particular lowering, or lifting, of the wing, and be structurally easier to implement compared to a non-parallel adjustment, which also includes a change in the orientation of the lowering section.

Furthermore, it can be provided that the lowering section is biased in the lowered position. Such a bias voltage is not fundamentally contrary to an active displacement, since it may be provided that a respective position is not assumed solely on the basis of the bias voltage, but only as a result of an interaction of the bias voltage with a user-controllable element. For example, it can be provided that the lowering section, for example by means of a spring device or merely due to gravity, is biased into the lowered position and that an urging element is provided which actively push the lowering section against the bias in the flush position and then in the flush Can hold a position. The zurückverstellen the Absenkabschnitts in the lowered position can then take place in particular by the fact that the urging member is withdrawn. The adjustment of the Absenkabschnitts in the lowered position in which it is biased, so takes place in the interaction of the urging with the bias and is in particular due to the controlled retraction of the urging no passive, but an active adjustment.

According to a preferred embodiment, the running rail for adjusting the Absenkabschnitts on at least one drive device with a lifting mechanism. The drive device is integrated in particular in the running rail. By such an embodiment can be advantageously utilized that in the region of the running rail, e.g. in the threshold of a door or a window, typically more space is available than on or in the wing of the lift-and-slide element. The lifting mechanism can in particular serve to derive a drive torque transmitted to the lifting mechanism for adjusting the lowering section of the running rail. In this case, the drive torque may in principle consist of a manual operation, e.g. from pivoting a swing lever or pressing a foot pedal.

According to a preferred embodiment, the drive device but in addition to the lifting mechanism also includes a motor, in particular an electric motor, which cooperates with the lifting mechanism. In this case, the drive torque may be generated by the motor and output to the lifting mechanism, which transmits it to the lowering section in a manner suitable for adjustment between the flush and lowered positions. The lifting mechanism can then be designed, for example, to derive a drive torque of the motor to a linear displacement of the Absenkabschnitts.

In principle, the possibility of a motorized adjustment by means of the motor can be provided in addition to a manually driven adjustment of the lowering section, so that a user can actively adjust the lowering element either manually or motorized as desired. For a motorized adjustment can be about an actuator, for example in the form of a push button, a toggle switch or a rotary switch, be provided by the motorized Adjustment triggered and, where appropriate, the direction of the adjustment can be specified.

Preferably, the motor is arranged in the mounted state of the track below the track. In this way it can be achieved, in particular, that the motor is not visible from the outside when the running rail is mounted. In a corresponding manner, the entire drive device can be arranged in the mounted state of the track at least substantially below the track, although for manual generation of the drive torque at least one actuator of the drive device can also be located above the track.

The lifting mechanism can basically be implemented constructively in many different ways. For example, the lifting mechanism may be designed in the manner of a toggle lever, be designed for a hydraulic power transmission and / or comprise a pneumatic cylinder. Such training can in particular allow moving even heavy wings with little effort.

According to a preferred embodiment, the lifting mechanism comprises an urging element, which is displaceable transversely to the direction of the adjustability of the Absenkabschnitts, in particular parallel to the track, and to urge the Absenkabschnitt depending on the position of the urging member in a respective position. In principle, the urging element can be designed to urge the lowering section into the flush position for adjustment into the flush position and, conversely, to force it into the lowered position for adjustment into the lowered position. In particular, however, if the lowering portion is biased in one of the two positions (eg the lowered position), it may also be sufficient for an adjustment of the Absenkabschnitts in this position, if the urging member can withdraw controlled, so that the lowering is adjusted due to the interaction of the urging member and the bias in this position. An urging of the Absenkabschnitts by the urging member then takes place only when adjusting in the other position.

According to an advantageous development, the urging element is designed as a wedge. The urging element may in particular be designed as a wedge, as it has an obliquely oriented to the direction of the displaceability of the urging member and obliquely to the direction of adjustability of the Absenkabschnitts inclined surface. This inclined surface can then cooperate with a corresponding obliquely oriented inclined surface of the Absenkabschnitts such that a displacement of the urging leads to an adjustment of the Absenkabschnitts. The interaction of the inclined surfaces comprises, for example, that the inclined surfaces abut each other and in particular that they slide along when moving the urging member to each other.

The displacement of the urging element can be done in various ways. Preferably, the urging member has a threaded bore to be displaceable by means of a threaded rod screwed into the threaded bore. Turning the threaded rod about its axis then causes the threaded rod to move in one direction or the other along its axis relative to the threaded bore, depending on the direction of rotation. If the threaded rod is mounted fixed in position thereby, consequently, a displacement of the urging member along the axis causes. Such a mechanism makes it possible to derive a drive torque to a linear movement in a structurally simple manner. The drive torque can be provided in particular by a motor which can drive the threaded rod to rotate about its axis.

In this context, it is preferred if the threaded rod and / or a motor driving the threaded rod is aligned parallel to the raceway. In such an orientation, the urging member and the threaded rod and possibly also the motor form an at least substantially elongate arrangement, which can be particularly well integrated into the track because of their alignment parallel to the track or at least so can be arranged below the track, that they after is not visible on the outside. Overall, thereby the space occupied by the running rail space can be kept compact.

Furthermore, it can be provided, in particular, that a respective lowering section is mounted so as to be displaceable in parallel via one or more, in particular vertically oriented, telescopic rods. For example, the lowering portion may have an at least substantially rectangular base surface, wherein the telescopic rods are arranged in corners of the base of the Absenkabschnitts, in each case in each corner in each case a telescopic rod. In principle, however, the adjustable mounting of the lowering sections can also be provided in other ways, e.g. by means of guided in grooves or slots pins.

Such a guide by means of pins, each engaging in a groove or a slot and therein along the, preferably straight, course of the groove or the slot are movable, can also be provided for the displaceable mounting of a respective urging member. For example, an urging element have transversely projecting pins transversely to the direction of its mobility, for example a pin on each side. The urging element can then be flanked on its two sides by a respective guide rail, which has a slot in which a respective pin of the urging element can be guided. The slot has in particular a straight, horizontally aligned course, by the length of which the displaceability of the urging element can be limited. Alternatively, the arrangement may just be reversed, so that on the guide rails respective pins and on the urging member respective grooves or slots are formed.

According to a further embodiment, the lifting mechanism may also comprise a slotted guide in order to derive an adjusting movement directed transversely to the direction of adjustability of the lowering section, in particular parallel to the track, to an adjustment of the lowering section. For example, the lowering section itself or an element coupled to the lowering section can be guided through the sliding guide. A slotted guide can be advantageous in particular if more complex movements are to be generated than merely a linear displacement. However, the slide guide can also serve, for example, to deflect a movement of an element of the lifting mechanism oriented transversely to the direction of the adjustability of the lowering section, in particular parallel to the running track, to an adjustment of the lowering section. For this purpose, the slotted guide, for example, both relative to the adjustability of said element as well as relative to the adjustability of the Absenkabschnitts have obliquely oriented grooves, engage in the pin of said element. Or conversely, the pins may be provided on the slide guide and the grooves on said element.

According to a preferred embodiment, the running rail has at least two mutually spaced lowering sections, which are active, in particular jointly, between a respective flush position and a respective lowered position, in particular motor, are adjustable to move the wing between the raised displacement position and the lowered fixing position when the wing with correspondingly spaced rollers of the roller arrangement is on a respective one of the lowering sections.

In particular, in order to be stored stable, the wing of each lift-and-slide element can interact with the running rail via two or more rollers. In such a case, it is advantageous if a corresponding number of Absenkabschnitten are provided on the running rail, which are arranged according to the arrangement of the rollers on the wing along the track. When the wing is in the travel position, it can be moved along its mobility in a position in which the rollers are each on one of the Absenkabschnitte. By actively adjusting the lowering sections from the flush position to the lowered position, the wing can then be moved from its displacement position into the fixing position. For this purpose, the adjustment of the Absenkabschnitte preferably synchronously, so that the wing controlled parallel offset, in particular lowered, without tilting. The lowering sections are adjusted in particular by a motor, but in principle can also be actively adjusted (alternatively or in addition to a motor adjustability) by means of a manually generated drive torque, which is transmitted to them in a suitable manner.

The embodiments described above for a running rail with at least one lowering section can be transferred, each with corresponding advantages, to a running rail with at least two lowering sections.

According to an advantageous development, the running rail for adjusting each of the at least two Absenkabschnitte each have a drive device comprising a lifting mechanism and a motor, in particular electric motor, which cooperates with the lifting mechanism and is preferably arranged below the track in the mounted state. In other words, each of the at least two lowering sections can be assigned a respective other drive device. This basically makes it possible to adjust the different Absenkabschnitte independently. The drive devices for different Absenkabschnitte but can also be operated synchronized to adjust the Absenkabschnitte together. Nevertheless, to provide for each Absenkabschnitte each separate drive devices, may be advantageous insofar as the individual drive devices, in particular the motors of the drive devices, can be designed for a lower power than when a single drive device, in particular a single motor, is provided for the plurality of lowering sections.

According to an alternative development, on the other hand, provision is made for the running rail to have a drive device for jointly adjusting the at least two lowering sections by means of a drive device, the drive device comprising a lifting mechanism and a motor, in particular an electric motor, which cooperates with the lifting mechanism and preferably in the mounted state is arranged below the track. According to this embodiment, a single motor may be sufficient to adjust the at least two lowering sections together. Although such a motor must be designed for a higher performance than if a separate drive device with motor is provided for the various lowering sections. However, the use of a single motor for several Absenkabschnitte has the advantage that not multiple motors for synchronous or at least coordinated adjustment of the various Absenkabschnitte must be controlled in a coordinated manner. In addition, an embodiment with a single drive device for several Absenkabschnitte requires less space.

In such an embodiment, the lifting mechanism, via which a drive torque of the motor of the drive device can be transferred to the lowering sections, in particular as described above, comprise an urging element. The urging element and optionally interacting with it elements can be designed according to the various embodiments described above. Preferably, a respective such urging element is provided for each of the at least two lowering sections, so that the drive device comprises at least two urging elements.

To be able to adjust the lowering sections in common and in particular always in a consistent manner, the at least two urging elements can advantageously be connected via a coupling element, in particular via a push rod, for a common displacement. By such a push rod can be ensured in particular that the urging elements are arranged at a fixed distance from each other, which is always maintained even with a displacement of the urging elements. Since the urging elements advantageously cooperate with a respective other of the at least two lowering sections, a common adjustment of the lowering sections can thus be ensured by the push rod. In particular, it may be sufficient, due to the coupling of the urging elements by the coupling element, to apply only one of the urging elements with a drive torque, thereby displacing not only this urging element but also all the further urging elements associated therewith. Since the motor consequently needs to be drive-coupled with only one of the urging elements and is then automatically coupled via the coupling element indirectly indirectly with one or more further urging elements, a simplified construction of the running rail results compared to an embodiment in which the motor is parallel is drivingly coupled with multiple urging elements.

The object mentioned at the outset is also achieved by a lift-and-slide element having the features of claim 16, which in particular comprises a running rail of the type described above. Preferred embodiments of the lift-and-slide element each have similar advantages in correspondence with the above-described embodiments of the slide rail.

The invention will be explained further by way of example only with reference to the figures.

Fig. 1

shows a schematic representation of a side view of an embodiment of a running rail according to the invention, on which a lifting slide element is arranged movable, wherein the lowering of the running rail are each in its flush position and the wing of the lifting slide element is in the displacement position.

Fig. 2

shows the in Fig. 1 shown embodiment in a corresponding representation, but with the lowering of the track rail are each in its lowered position and the wing of the lifting slide element is in the fixing position.

The Fig. 1 and 2 show a lifting slide element 13 in the form of a lift and slide door, which comprises a wing 15 and a roller assembly 17 and of which only a lower part is shown. Furthermore, a running rail 11 is shown, which forms a raceway 19 for the lifting slide element 13, on which the wing 15 by means of the roller arrangement 17 is movable. In this case, the roller arrangement 17 is provided on the underside of the wing 15, so that the running rail 11 can be laid in a threshold in the ground, over which the wing 15 extends. In principle, however, the roller arrangement 17 could, for example, also be arranged on an upper side of the wing 15, so that the wing 15 is suspended, as it were, on the running rail 11.

In the running rail 11 two Absenkabschnitte 21 are provided at a defined distance from each other. This distance corresponds to the distance between two rollers 23 of the roller arrangement 17, wherein the rollers 23 are formed in the embodiment shown as a carriage with two wheels, which roll on the track 19 during the process of the wing 15. Basically, a respective Roller 23 but also be designed differently, for example, comprise only one wheel.

Along the track 19, the wing 15 can be moved substantially continuously in different positions. In the figures, a limit position of the movability of the wing 15 is shown, in which the wing 15 closes a passage. In this respect, it is at this limit position to the closed position of the wing 15. In this position, the wing 15 with each of its two rollers 23 of the roller arrangement 17 on a respective other of the two Absenkabschnitte 21 of the running rail eleventh

Like a comparison of Fig. 1 and 2 illustrated, the Absenkabschnitte 21 are common between the in Fig. 1 shown flush position and the in Fig. 2 shown lowered position adjustable, wherein the adjustment corresponds to a parallel offset, in which the orientation of the Absenkabschnitte 21 does not change. Since the wing 15 stands with the rollers 23 on the lowering sections 21, moves by such adjustment of the Absenkabschnitte 21 and the wing 15th

In doing so, the in Fig. 1 In this state, in which the lowering sections 21 are aligned with the adjacent sections of the running rail 11, so that a continuous flat track 19 is formed, the wing 15 can freely along the track 19 are moved, for example, to move the wing 15 along the track 19 in an open position.

In Fig. 2 on the other hand, the wing 15 is in a lowered fixing position, in which it is lowered relative to the displacement position. This fixing position is a consequence of the lowered position of the lowering sections 21, which are offset relative to the flush position so down that a respective recess in the Running track 19 is created, which is bounded on both sides by a step. The rollers 23 of the roller assembly 17 of the wing 15 are so deeply absorbed in these wells that they can not overcome the respective stage in an attempt to move the wings 15 horizontally. As a result, the mobility of the wing 15 is substantially limited. Since the length of the lowering sections 21 in the exemplified embodiment at least substantially corresponds to the extent of the rollers 23 in the direction of the track 19, the wing 15 is substantially completely prevented even in a method. Alternatively or in addition to this type of fixation, the wing 15 in the lowered fixing position can also sit with its underside on the track 19 or the adjacent floor (not shown) and be prevented due to friction on a method. In the Fig. 2 shown fixing position thus allows the wing 15 at least in a certain, defined by the position of the Absenkabschnitte position along its movability, especially in the closed position shown to fix.

The adjustment of the Absenkabschnitte 21 is active. In particular, the lowering sections 21 for adjustment from the lowered position ( Fig. 2 ) into the flush position ( Fig. 1 ) is urged upwards by means of a drive device 25. The drive device 25 comprises a lifting mechanism 27, which is driven by an electric motor 29, so that the lifting mechanism 27 transmits a drive torque of the electric motor 29 to the respective lowering section 21. The lifting mechanism 27 has two wedge-shaped urging elements 31 which can be pushed by the drive torque of the electric motor 29 to different degrees below a respective one of the lowering sections 21. Be the urging elements, as in Fig. 1 shown, pushed far below the lowering sections 21, they push the lowering sections 21 in the flush position and thus the wing 15 in the raised displacement position.

For a reverse adjustment, the urging members 31, on which the Absenkabschnitte 21 are supported, pulled back under the Absenkabschnitten 21, so that the Absenkabschnitte 21 controlled lowered into the lowered position and thus the wing 15 is moved to the lowered fixing position. The lowering sections 21 are biased by gravity in the direction of the lowered position. But only by the retraction of the urging members 31, the movement of the Absenkabschnitte 21 and the wing 15 is allowed down in a controlled manner. Therefore, not only the displacement of the Absenkabschnitte 21 in the flush position by the urging of the urging elements, but also the displacement of the Absenkabschnitte 21 in the lowered position due to the interaction of gravity with the urging an active displacement, especially the displacement in both directions motor displacement of the urging elements 31 by means of the electric motor 29 requires.

The urging elements 31 are each displaceable parallel to the track 19 and thus transversely to the direction of adjustability of the Absenkabschnitte 21. As a result, the running rail 11 can have a comparatively small extent downwards (relative to the assembled state, which is shown in the figures). For deflecting the adjusting movement of a respective urging element 31 onto a respective lowering section 21, both the urging elements 31 and the lowering sections 21 each have inclined surfaces 33, 33 ', which are aligned parallel to each other, at least for a respective lowering section 21 and the urging element 31 cooperating therewith the inclined surfaces 33, 33 'of this respective lowering section 21 and of this respective urging element 31 abut one another and slide along one another when the urging element 31 is displaced.

For motorized displacement of the urging elements 31, one of the urging elements 31 has a threaded bore 35 into which a threaded rod 37 is screwed is. The threaded rod 37 is coupled to the electric motor 29 so that it can be driven by the electric motor 29 to rotate about its axis. The threaded rod 37 and the electric motor 29 are arranged parallel to the track 19 below the track 19, which allows a compact design of the track rail 11. Since the threaded rod 37 is mounted fixed in position, a rotation of the threaded rod 37 via the interaction with the threaded bore 35 leads to a displacement of the urging member 31 in the direction of the axis of the threaded rod 37 and thus parallel to the raceway 19th

The urging element 31 that can be displaced by motor means in this way is connected to the further urging element 31 (in the figures on the left) via a coupling element in the form of a push rod 39. The push rod 39 connects the urging elements 31 in such a way that they can only be displaced together while maintaining the same distance from one another. Thus, the displacement of the one urging 31, which is drivingly connected to the electric motor 29 via the threaded rod 37, via the push rod 39 also leads to a corresponding displacement of the other urging element 31. In this way, a single electric motor 29 is sufficient to both urging elements 31st and thus to adjust both lowering sections 21 of the running rail 11.
