Description

The invention relates to a fitting system for a sliding sash as a sliding sash or a sliding lift-and-slide sash of a window or a door according to the preamble of claim 1.

Generic windows or doors are already known. Hardware for windows and doors with motor drives is increasingly being offered. This also applies to windows and doors that can be moved vertically or horizontally. In the case of a vertically displaceable wing, the wing is held in lateral running or guide rails. The connection is made via guide pieces, which are attached directly or indirectly to the wing and received in the running rails. Depending on the sash weight, it can be provided that the sash weight is absorbed via a relief device, so that the operator only has to exert a small amount of force in the case of manual operation.

The sliding sashes of systems as sliding sashes or lifting-sliding sashes for a window or a door often have a relatively high mass. When moving the sash, especially when pushing the sash from a standing position, a high force must be absorbed to open it. Closing also requires the application of a resistance to the weight of the wing. Known drives are visibly mounted on the window or door and are shielded with an additional cover, which greatly affects the appearance. Likewise, the risk of injury during assembly is increased by components that are visible in a disruptive manner. Furthermore, visible components offer more possibilities for manipulation from the outside. An assembly of such a drive device has proven to be complex from the known prior art. For the transmission of signals and / or energy there is a lack of space due to the construction to lay the necessary lines or cables simply and inexpensively. Additional bores and / or cutouts on the sash and / or on the frame increase the installation and time expenditure considerably, which has a disadvantageous effect on a sliding system.

From the EP 2 063 058 B1 a sliding window or a sliding door with a window frame has become known in which a sliding sash is movably held, which is movable via a drive and can be coupled to the window frame via locking means, the sliding sash having four frame profiles fixed to one another. The drive comprises a driven drive roller around which a tensioning element fixed to the frame is wound, the tensioning element being guided over two deflection rollers and running into a hollow chamber of the frame profile.

The present control device for the guide rail can only be reached via a deflection to the guide rail due to the vertical installation in a vertical spar of the wing, which complicates the structure in an expensive manner and requires a correspondingly large amount of installation space in the wing. In addition, the components of the control device are widely spaced apart from one another by the guide rail, which complicates assembly and the required integration of an energy transmission means from an energy and / or control unit due to individual component components.

Reference is also made to the EP 1 206 619 B1 . There is provided a motorized door unit with a frame unit which is constructed and arranged to be installed in an opening formed by a building wall. The frame unit provides a door opening that allows people to get from one side of the building wall to the other side of the building wall when the door unit is installed. Also, a generally perpendicularly extending door panel attached to the frame unit, the door panel being constructed and arranged to move relative to the door opening of the frame unit. A sliding door unit is shown in which a pair of movable door panels are fastened in the center of a frame unit in a door opening. A pair of stationary door panels are attached to opposite ends of the frame assembly adjacent the respective posts. The central door panels are moved between the open and closed positions by a single axial drive mounted within an upper portion of a vertically extending side member of a stationary door panel. The drive end member of the axial drive extends up into the lintel of the frame unit and is functionally provided with a door moving structure in the form of a horizontally extending belt and wheel system.

Also in the case of the door unit known above, the drive opposite the belt and wheel system extending in the upper horizontal door lintel is fastened in a vertical door panel of a side element, a functional connection only being achieved via a deflection to the belt and wheel system of the guide rail becomes, which complicates the construction costly and accordingly requires a lot of space in the wing. The Components of the drive and the control device are installed at a distance from one another by the belt and wheel system in different door panels, frame units or in the door lintel of the sliding door unit, which makes assembly and the supply of electrical energy difficult due to the great distance between the power source and the drives.

In addition, the DE 20 2017 100 365 U1 a sliding system comprising a door panel slidably mounted with respect to a fixed housing and adapted to selectively open or close an opening, the system comprising an electrical supply source integrated with the fixed housing. With a motor that is mounted in the door leaf. Further with a drive means cooperating with a guide mounted on the box, a supply cable connecting the electrical supply source to the motor and the electrical supply cable being associated with means suitable for tensioning the cable along the displacement of the door leaf hold. The sliding system proves to be visually appealing due to its concealed construction. The arrangement of the supply cable between the electrical supply source and the motor turns out to be an optical disadvantage due to the large construction with the need for a tensioning element. Furthermore, the execution is expensive and requires a lot of installation space.

The object of the present invention is therefore to eliminate the known deficiencies and, in contrast, provides a system with a drive for a sliding sash as a sliding sash or lifting-sliding sash for large portability and optimal guidance for a window or door at low cost and little installation space , which also achieves the connection of an electrical power source with a drive system in a simple, fast, safe and precise way and can also be retrofitted, dismantled and adjusted.

This object is achieved by a sliding system for a sliding sash as a sliding sash or a sliding lift-and-slide sash of a window or door with the features of claim 1.

The sliding system must be arranged in such a way that it is suitable for a sliding sash as a sliding sash or a sliding lift-and-slide sash for a window or door. The movable wing has at least two carriages with rollers in order to be displaced on a running rail in a direction parallel to the extension of the wing or along a running rail. For the automatically displaceable actuation of the wing, an operating element with a switch is preferably provided on a vertical spar, which selectively controls a drive device. By actuating the control element, the movable leaf can be moved from a closed position to move one against a fixed frame and a fixed wing or door panel. On the other hand, the sash can also be brought into a secured, shifted ventilation position or an area of a through opening. The wing is advantageously held movably supported on the frame by means of carriages having the bottom side and supported on a running rail.

Operation of the drive device via a remote control unit or a smart home system is also conceivable. For this purpose, a control unit is provided on the window or the door. For this purpose, the control unit is preferably accommodated in a wall of a building and is connected to the operating element and the drive device via control lines.

The operating element can also control a drive which is arranged in the closing direction at the front of the vertical spar and which also transfers locking means on the vertical spar into a locked closed position or into an unlocked open position of the sash. Manual actuation by means of an actuating handle with transmission of an actuating linkage to the locking means is also conceivable.

In a system of a slidable lift-slide sash of a window or a door, the movable sash can be moved automatically by the drive via the operating element or via the manual operating handle from the closed position through a coupled connection of the operating linkage to the carriage into a raised open position then to be able to be moved by the drive device.

Likewise, both of the actuation variants described above can also be arranged in a window or a door, which can be selected according to the requirements and have the character of a hybrid system. Additional drives selected for the system are also connected to the control lines and linked to the control unit.

So that these positions of the sash are possible relative to the fixed frame and to the fixed sash or the fixed door panel, a special fitting arrangement, namely a so-called system for sliding sash or sliding lift-and-slide sash, is provided between the movable sash and the fixed frame.

According to the invention, the slidably held sash is provided in the frame as a sliding sash or slidable lift-and-slide sash of a window or door, the sash having a drive device for moving the sash. Around the drive device, which consists of a drive motor arranged on the wing side in a housing and a drive roller driven on it, winds with the drive motor, which is clamped to the frame in a guide rail drive belt connected to the drive. An electrical connection in the form of a control line with an at least partially encased for the transmission of signals and / or energy is arranged between the sash and the frame.

In order to create space for further components of the sliding system, the length of the drive belt arranged on the upper horizontal wing spar of the wing can be adapted to the upper horizontal frame spar of the window frame . A first end and a second end with the same length of the sash or sliding sash and the fixed door field reach the respective vertical frame spars of the window frame, with two guide rollers arranged on the horizontal sash spar deflecting the drive belt and in two horizontally next to each other at a different height Dividing drive belts having levels. With different lengths of the leaf or sliding leaf from the fixed door field, the respective ends can be arranged at a distance from the vertical frame bars of the window frame.

The spatial division of the drive belt into two drive belts that are different in height and run horizontally creates a space that is used for laying the control line. Thus, in an advantageous embodiment, the control line can be transferred through the developing shoulder of the drive belt by means of two guide rollers from an adjacent position on the upper level of the drive belt of the drive belt to the lower level of the drive belt of the drive belt with rotation of a loop forming 180 °.

When the sash moves, the control line follows the sash into the closed or open position. The different levels of the drive belt create a large installation space for the transition of the control line from the control or energy unit on the frame to the drive motor arranged on the sash. During the movement of the wing, the control line shifts with the wing on the lower level, whereby the control line, which is arranged on the upper level, continuously adapts to the course of movement as the length changes.

If the leaf moves in the direction of the closed position, the control line follows the leaf on the lower level of the drive belt, the length of the control line on the upper level of the drive belt being extended.

The control line behaves in the opposite way with the direction of movement of the sash in the open position of the window or door. The control line moves on the lower level of the drive belt with the wing extending in the direction of the open Position of the window or the door, with the length of the drive belt being relatively shortened when it lies on the upper level of the drive belt.
The drive belt itself continuously changes the length dimensions of the drive belts during the movement of the wing in relation to the constant overall length due to the horizontal change in position of the guide rollers within the maximum course of movement of the wing.

In order not to impair the existing optics of the window or door, the drive device is arranged almost completely hidden in a recess or receiving groove of the upper, horizontal sash spar at one end of the sash and the guide rail arranged on the frame when the sash is installed. For an improved assembly, the drive motor and the drive roller are mounted as a structural unit in the housing and the drive belt can be fixed in a tensioned manner at the respective free ends by means of fastening elements in the guide rail.

The height of the drive belt to the drive device is formed as a function of the horizontal axes and / or the respective diameter of the guide rollers mounted in a deflection device. Preferably, with the possible displacement of the axes of the guide rollers within the deflection device and / or with a direct change in the size of the diameter of the guide rollers, the height of the drive belt and thus the respective drive belts can be aligned with one another as required, in particular the available installation space.

In addition, it has proven to be advantageous for the function, assembly and cost of the fitting that the deflection device is formed from a housing which rotatably accommodates the guide rollers and forms a guide contour for the loop of the control line. In order to meet all the requirements for the necessary guides and holders for the control line and the guide rollers in a cost-effective manner, the housing is preferably made of a plastic.

For simplified assembly with the deflection device resting on a corner between the vertical wing spar on the lock side and the upper horizontal wing spar of the wing, the deflection device can be attached to the wing without additional tools for positional positioning.

For a secure connection between the drive belt and the control line during the sliding movement of the sash towards the frame, the casing has magnets which, with their magnetic field, allow the control line to be attached to the drive belt. In the subject matter of the invention, the control line is divided into two parallel planes on, the control line from the drive belt running above the drive motor in the direction of the frame and the lower drive belt with driving wings running almost on the same level of the drive motor in the direction of the wing automatically alternately and comes to rest when attached. Further fastening means such as adhesive connections or latching or pressure connections are also conceivable for an effective connection of the control line to the drive belt.

The line means of the control line is preferably a busbar which is formed from one or more cables, a control unit controlling the flow of electricity from the power source to the drive motor.

The sheath of the control line can preferably be an overmolded plastic, designed as a wrapped bandage, or a cable duct housing with preferably an energy chain. In this case, the magnets are preferably set in an adhesive manner at a distance from one another via an adhesive connection in the casing and are also adhesively bonded to the drive belt.

The advantage of the magnet attachment is that magnets are present on both the control line and the drive belt, the magnets being brought into mutual alignment during assembly and releasably connecting the control line to the drive belt. One or two magnets per stop point can be attached to the control line as well as to the drive belt. The advantage of this type of fastening is that a high level of force can be achieved. This allows a reduced number of breakpoints to be used. In addition, when using two magnets each time, the control line can be positioned very precisely. The connection of the magnets to the control line can be made, for example, while the plastic is being sprayed to produce the cover, or can be achieved by gluing onto the power line.

Another advantage is that the magnetic field of the magnets of the control line interacts with a ferromagnetic drive belt.

Preferred exemplary embodiments of the invention are shown schematically in the drawing and are explained in more detail below with reference to the figures of the drawing.

The Fig. 1 shows a perspective view of a window or a door 3, a frame 4 with a displaceable leaf 2 and a permanently mounted leaf or door field 40, which is adjacent to this. To actuate the movable wing 2, an operating element 41 with a switch is provided on a vertical spar 42, which controls a drive device 1. With actuation of the operating element 41, the movable wing 2, for example from the in Fig. 1 having closed position in a according to the direction of the arrow with respect to the fixed frame 4 and the fixedly mounted leaf or door panel 40 in an open position Fig. 5 move, but on the other hand also bring into a securely displaced ventilation position or an area of a through opening. The wing 2 is hanging over one or more or after Fig. 1 Carriages 46 having the bottom side, supported on a running rail 45 and held on the frame 4 so as to be movable.

Operation of the drive device 1 via a remote control unit or a smart home system is also possible. This is on the window or door 3 after Fig. 10 a control unit 48 is provided. The control unit 48 can also be accommodated in a wall of a building and is connected to the operating element 41 and the drive device 1 via control lines 47.

The operating element 41 can also control a drive (not shown) at the front in the closing direction on the vertical spar 42, which also transfers the locking means on the vertical spar 42 (not shown) into a locked closed position or into an unlocked open position of the leaf 2. Manual actuation by means of an actuating handle with transmission of an actuating linkage to the locking means is also conceivable.

In the case of a sliding system of a sliding lift-and-slide sash 2 of a window or a door 3, the movable sash 2 can be moved out of the in the - not shown - drive over the operating element 41 automatically or via the manual operating handle Fig. 1 having closed position by a coupled connection of the actuating linkage on the carriage 46 in a raised open position, so that it can then be moved by the drive device 1.

Likewise, both of the actuation variants described above can also be arranged in a window or a door 3, which can be selected according to the requirements and resemble the character of a hybrid system. Additional drives selected for the system are also connected to the control lines 47 and linked to the control unit 48.

So that these positions of the sash 2 relative to the fixed frame 4 as well as to the permanently mounted sash or to the fixed door panel 40 are possible, a special fitting arrangement, namely a so-called system for sliding sashes or sliding lifting devices, is provided between the movable sash 2 and the fixed frame 4. Sliding sash provided from which in the Fig. 1 For the sake of simplicity, only the control element 41 on Wing 2, part of a lower running rail 45 for the carriage 46 and an upper guide rail 8 according to Fig. 6 and Fig. 10 are hinted at.

After Fig. 2 the drive device 1 comprises a drive motor 6 arranged on the wing side with a drive roller 7 driven thereon. The drive roller 7 is after FIGS. 3 to 9 positively guided by a drive belt 9 arranged on the frame 4 in the guide rail 8. After Fig. 1 and Fig. 5 the drive device 1 in the installed position of the sash 2 is arranged almost completely concealed in a recess or receiving groove 23 of an upper, horizontal sash spar 12 of the movable sash 2 and a guide rail 8 arranged on the frame 4. The drive motor 6 and the drive roller 7 are reproduced as a structural unit Fig. 2 stored in a housing 5. The drive belt 9 is after Fig. 4 in the closed position almost completely from a guide cross-section of the guide rail 8 forming a support Fig. 6 encompassed. A gap in the guide rail 8 forms an opening and thus the possibility of coupling between the components arranged on the sash 2 and the components of the drive device 1 mounted on the frame 4.

The movable wing 2 comprises according to Fig. 1 and Fig. 10 four spars 12, 42, 43 and 44, which are designed as hollow profiles, in particular as aluminum or plastic profiles, or as solid profiles made of wood. The bars contain prefabricated recesses or grooves for the concealed installation of hardware components. Thus, the drive device 1 is provided in the upper horizontal spar 12, which is arranged facing the vertical spar 43 ( Figure 1 ). The wing-side components of the drive device 1, in particular the housing 5, are designed to be adapted in terms of the height and width of the recess or receiving groove 23 of the upper horizontal spar 12 of the wing 2. Additional work steps for mounting the drive device 1 on the wing 2 are thus omitted.

Between wing 2 and frame 4 is after FIGS. 3 to 9 an electrical connection in the form of a control line 10 with an at least partially comprising sheath 11 for the transmission of signals and / or energy.

In order to create a large installation space for further components of the sliding system, the length of the drive belt 9 arranged on the upper horizontal wing spar 12 of the wing 2 is adapted to the specifications of the desired opening width of the wing 2 of the upper horizontal frame spar 13 of the window frame 4 ( Figure 2 ). S219105 according to Fig. 2 a first end 14 and a second end 15 9 zoom range of the drive belt to the respective vertical frame members 16, 17 of the frame 4, two arranged on the horizontal wing spar 12 guide rollers 18, 19 by FIGS. 4 and 5 the drive belt 9 deflect and divide it into two drive belts 20, 21 which are horizontally next to one another at a height H in different planes. In the Figures 3 to 5 , as FIGS. 7 and 9 it becomes clear that the control line 10 moves through the developing shoulder of the drive belt 9 by means of two guide rollers 18, 19 from an adjacent position of the sub-section of the guide roller 19 on the upper level of the drive belt 20 of the drive belt 9 to the lower section of the guide roller 18 and the lower level of the drive belt 21 of the drive belt 9 can be further transmitted with rotation of a 180 ° forming loop 22.

With the movement of the leaf 2, the control line 10 follows the leaf 2 in the direction of arrow 32 into the closed position Fig. 4 or to the open position Fig. 5 in the direction of arrow 33. The different levels of the drive belt 9 - illustrated in Fig. 5 - cause a large installation space for the transition of the control line 10 from the control or energy unit 48 on the frame 4 to the drive motor 6 arranged on the wing 2. During the movement of the wing 2, the length of the control line 10 is shifted with an imaginary vertical parting plane by the guide rollers 18, 19 forming the shoulder on the respective levels of the drive belt 20 and 21.

If the wing 2 moves after Fig. 4 in the direction of the closed position, the control line 10 follows the wing 2 on the lower level of the drive belt 21, the length of the control line 10 on the drive belt 21 being reduced and the length of the control line on the drive belt 20 increasing continuously.

The control line 10 behaves in the opposite way with the direction of movement of the sash 2 in the open position of the window or door 3 Fig. 5 . The control line 10 moves on the lower level of the drive belt 21 adjacent with the sash 2 in the direction of the open position of the window or door 3 and reduces the length of the adjacent control line 10 on the upper level of the drive belt 20, the length of the control line 10 increases continuously on the lower level of the drive belt 21.

With a constant, constant overall length, the drive belt 9 continuously changes the ratio of the length dimensions of the drive belts 20, 21 during the movement of the wing 2 through the horizontal change in position of the guide rollers 18, 19 within the maximum course of movement of the wing 2.

After Fig. 1 it is shown that the sliding system for a window or the door 3 is installed completely concealed. For this purpose, the drive device 1 is in the installation position of the wing 2 Fig. 2 almost completely in the recess or receiving groove 23 Fig. 6 of the upper, horizontal wing spar 12 is arranged at one end of the wing 2 and the guide rail 8 arranged on the frame 4. For improved assembly, the drive motor 6 and the drive roller 7 - not shown - are stored as a structural unit in the housing 5, with the drive belt 9 being fixed at the respective free ends 14, 15 in a tensioned manner in the guide rail 8 by means of fastening elements 24, 25 is.

The height H with a height difference of the drive belt 9 in two divided levels to the drive device 1 according to Fig. 5 , is formed depending on the horizontal axes and / or the respective diameter of the guide rollers 18, 19 mounted in a deflection device 26. With the displacement of the axes of the guide rollers 18, 19 within the deflection device 26 and / or with a direct change in the size of the diameter of the guide rollers 18, 19, can easily align the height H of the drive belt 9 and thus of the respective drive belts to one another as required, in particular adapted to the available installation space. With a larger installation space, the loop 22 of the control line 10 can be made larger in diameter, which has a positive effect on the durability of the control line 10.

After Figs. 3 to 4 and Fig. 7 the deflecting device 26 is formed from a housing 27 which accommodates the guide rollers 18, 19 in a rotatable manner and forms a guide contour 28 for the loop 22 of the control line 10. In order to produce all the necessary guides with sliding properties and mounts for the drive belt 9, the control line 10 and the guide rollers 18, 19 inexpensively, the housing 27 is preferably made of a plastic.

With the deflection device 26 resting on a corner 29 between the vertical wing spar 42 on the closure side and the upper horizontal wing spar 12 of the wing 2 after FIGS. 3 to 5 , the deflection device 26 can be fixed in the correct position at the transition from the vertical wing spar 42 to the horizontal wing spar 12 and attached to the wing 2 in a force-locking manner by means of fastening screws.

For a secure connection between the drive belt 9 and the control line 10 during the sliding movement of the sash 2 to the frame 4, the sheath 11 of the control line 10 points to Fig. 3 , FIGS. 7 and 9 Magnets 30 which, with their magnetic field, allow the control line 10 to be attached to the drive belt 9. In the subject matter of the invention, the control line 10 is divided Fig. 5 in two parallel planes, the control line 10 from the drive belt 20 running above the drive motor 6 in the direction of the frame 4 and the lower drive belt 21 with the driving wing 2 running almost on the same plane of the drive motor 6 in the direction of the wing 2 and automatically and alternately comes to rest due to the magnetic field. As well Conceivable for an effective connection of the control line 10 to the drive belt 9 are further fastening means, not shown, such as adhesive connections or latching or pressure connections. The control line 10 contains at least one busbar which is encompassed with electrical insulation. In the casing 11 of the control line 10, which can be made in one or two parts, the magnets 30 are embedded, which act as holding magnets with corresponding magnets 31 on the drive belt 9 after the assembly of the control line 10 on the flat bottom of the drive belts 20, 21 and the control line 10 attach to it. The alignment of the poles of the interacting magnet pairs 30, 31 must of course be selected accordingly so that an attractive force is created and so that the two magnet pairs can optimally coincide. With the intended positioning, the south pole S of one magnet must coincide with the north pole N of the other magnet. As a result, the magnetic forces can be used to virtually automatically find the position of the control line 10 on the drive belt 9. The number of magnets 30, 31 to be used depends on the length of the control line 10 and its weight. It is advantageous to include at least two holding magnets in the transferring 11 when viewed across the cross section.

The conduction means of the control line 10 is a busbar which is formed from one or more cables, with a control unit 48 controlling the flow of electricity from the power source to the drive motor 6.

The sheath 11 of the control line 10 can preferably be an overmolded plastic, as a wrapped bandage, or a cable duct housing, preferably with an energy chain. The magnets 30 are adhesively embedded in the casing 11 at a distance from one another via an adhesive connection and are likewise adhesively bonded to the drive belt 9.

The advantage of the magnet attachment is further that magnets 30, 31 are present on both the control line 10 and on the drive belt 9, which are brought into mutual alignment during assembly. On the control line 10 as well as on the drive belt 9, one or two magnets 30, 31 can be attached per stop. The advantage of this type of fastening is that a high level of force can be achieved. This allows a reduced number of breakpoints to be used. In addition, when using two magnets 30, 31 each, a very precise positioning of the line can be achieved. The connection of the magnets 30 to the control line 10 can, for example during the injection of the plastic, also be connected to produce the casing 11, or by gluing onto the control line 10.

In addition, it has proven to be advantageous for the function, assembly and cost of the fitting that the sliding system according to the invention can be mounted on the actuating linkage of the window or door 3 independently of the fitting. Subsequent assembly of the sliding system is also possible without any problems when the window or door 3 has already been installed, due to the design and location. As a result, the integral unit is easily accessible at the same time and can also be replaced if necessary. In principle, the proposed comfort configuration can be implemented simply and inexpensively by the features described for a sash 2 or a lifting-sliding sash of a window or door 3.
