Description

The invention relates to a door or window with a displaceable sash as a sliding sash or displaceable lifting and sliding sash, a window frame in which the sash is held displaceably, and a drive device for the sliding door system according to the preamble of claim 1.

The sliding sashes of systems as sliding sashes or lift-sliding sashes for a window or 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 resistance to the weight of the wing. Known drives are mounted visibly on the window or door and are shielded with an additional cover, which greatly impairs the optics. The risk of injury during assembly is also increased by components that are visible and are in the way. Furthermore, visible components offer more opportunities for manipulation from the outside. An assembly of such a drive device proves from the known prior art to be expensive.

Furthermore, drives that are arranged in a concealed manner are known, but they can only be integrated with great effort and in profile systems that are only unsuitable. In particular, the milling effort in the profile proves to be very high and can lead to high costs and weakening of the structure of the window or door elements.

Furthermore, power is usually transmitted in such sliding door systems by means of a belt drive, which requires additional components and must be taken into account from the start when designing and constructing a sliding door system. Retrofitting manual sliding door systems with motorized drives is therefore not possible with the previously known drive solutions, or only with great effort.

In addition, the drives usually include an interface by means of which electrical energy and/or control signals can be fed into the drive via a cable. A direct wired connection for motor operation is complex to assemble and requires additional assembly space. Millings in the sash or frame are possible. In order to be able to carry this out, you need special tools, a lot of time and special professional skills. A wired variant is therefore complex to install and proves to be disadvantageous for a concealed door or window.

Wireless connections to a drive of a motorized sliding door system are also known, with the power transmission being generated via so-called spring-loaded plunger contacts. These are arranged on the front face of the sash on the locking side, and when the sash is closed in the locked position, they hit a corresponding contact counterpoint in the arranged frame and thus establish a connection to a power supply. The known arrangement of the remote contact point can only be installed depending on a fixed installation point, for example on a vertical window frame strut. A system of a window or a door with wings running against each other to close them cannot be realized with the known system. In addition, a concealed arrangement of the opposite contact point on the window frame is also only possible with complex cutouts in the vertical window frame strut, which has a disadvantageous effect on assembly and also on costs.

The is known WO 2014/097211 A1 Which has a door or window with a sliding sash as a sliding sash or sliding lift-sliding sash, a frame in which the sash is slidably held and a drive device. For moving the wing, the drive device comprises a drive motor arranged on the frame side with a threaded spindle driven thereon. The threaded spindle is positively guided around a toothed rack element arranged on the wing. The drive motor and the threaded spindle are mounted as a structural unit in a housing.

In addition, the DE 202005000165 U1 a drive device in which the motor-gear unit is arranged in a receiving groove of an upper horizontal spar of the wing and a rack element is arranged in the guide rail. This unit includes a bevel gear that translates rotation of the motor shaft about a horizontal axis into rotation of a shaft about a vertical axis. The shaft drives a pinion which meshes with the rack member. The carriage of the sliding door is designed in such a way that the upper horizontal beam of the wing and the guide rail are spaced apart from one another in the vertical direction. Furthermore, the drive device has a power supply. For this purpose, the power supply is arranged outside of the sliding device and continuously supplies a power supply conductor arranged over the entire length of the running rail with current, which is connected to a current collector on the carriage is operatively connected and drives the electric motor. The permanent contact between the power supply conductor and the current collector during the continuous adjustment of the sash to the frame can wear out rapidly and lead to a permanently recurring problem up to the complete failure of the window or door element. Possible complaints are the result.

The object of the present invention is therefore to eliminate the known disadvantages. In addition, a drive for a sliding sash as a sliding sash or lift-sliding sash for large carrying options and optimal guidance for a window or door is provided at low cost and with little installation space, which is also retrofitted and adjusted in a simple, fast, safe and precise manner as well as can be demolished.

This object is achieved by a door or window with a displaceable sash as a sliding sash or displaceable lifting and sliding sash, a window frame in which the sash is held displaceably and a drive device with the features of patent claim 1.

The drive device is to be arranged in such a way that it is suitable for a displaceable wing as a sliding sash or displaceable lifting and sliding sash for a window or a door. In this case, the movable wing has at least two carriages, each 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 controls a drive device. By actuating the operating element, the movable sash can be moved, for example, from a closed position into one in relation to a fixed window frame and a sash or door panel mounted in a fixed location. On the other hand, the sash can also be brought into a secure, shifted ventilation position or an area of a passage opening. The sash is supported in an advantageous manner on the bottom side having carriages on a running rail on the frame movably held.

Operating 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. The control unit can be accommodated in the window frame or in a wall of a building and is connected to the operating element and the drive device via control and/or power lines.

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

In a system of a displaceable lifting and sliding sash of a window or a door, the movable sash can be moved by the drive via the operating element automatically 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, in order to then to be able to be moved by the drive device.

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

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

Advantageously, the drive device for moving the wing includes a wing-side arranged drive motor with a threaded spindle driven thereon. The threaded spindle is positively guided around a toothed rack element arranged on the window frame. A concealed arrangement of the drive device is made possible by the fact that the drive device is mounted almost completely in the installed position of the movable wing in a recess or receiving groove of an upper, horizontal spar of the movable wing and a guide rail arranged on the frame. For optimal storage of the drive components of the drive device, the drive motor and the threaded spindle are mounted as a unit in a housing. The rack element is almost completely encompassed by the guide rail. The receiving groove on the upper horizontal beam of the movable sash forms an opening at the respective free end with the possibility of coupling between the sash-side components and the frame-side components of the drive device.

The feature that the drive motor and the threaded spindle for a rotary transmission of the movement proves to be cost-effective and with a constructive advantage a gear transmission, a positive connection of a flexible shaft or a cardan are drive-connected in the longitudinal direction to the displacement direction of the wing.

The movable wing comprises four spars, which are designed as hollow profiles, in particular as aluminum or plastic profiles, or as solid profiles made of wood. The struts contain prefabricated recesses or receiving grooves for concealed assembly of fitting components, in particular for the drive device. Thus, in the upper horizontal beam and pointing to the vertical beam, the drive device is mounted in a recess or receiving groove. The wing-side components of the drive device are preferably designed to be adapted in height H and width B to the recess or receiving groove of the upper horizontal spar of the wing. Additional work steps for mounting the drive device on the wing are therefore omitted.

Thus, an accumulator is mounted in an advantageous manner on the lift-and-slide sash, which is in continuous electrical contact with the drive device during a movement of the movable sash or when the sash is in a stationary position. In this case, the movable sash in a resting position, for example in the closed position or in a locked position, receives current bridging the window frame via a contactor which is in the extension of the toothed rack element and has a contact point, the electrical contact from a power source arranged on the window frame or in a building wall to the drive device. For this purpose, a contact lug arranged on the drive device moves into a groove of the contactor when the lift-and-slide sash is moved horizontally by the electric drive motor and closes the contact for a current flow when retracted. To enable electrical contact to be established between the contactor and the contact lug, the groove is open for retraction in the direction of the wing.

In a preferred embodiment, the accumulator, or accumulator for short, is arranged in a concealed manner in the receiving groove of the upper, horizontal strut of the lift-and-slide sash near the drive motor. This ensures a secure power supply from the power source to the drive motor. In addition, the visual appearance of the window or door remains unaffected by the power supply chain, since all components of the drive device are arranged concealed in the window or door.

Simple assembly and assembly of the contactor, which transmits the electrical current from the power source to the drive components, is made possible by the fact that the contactor is held vertically in a profile groove of the guide rail, but is joined so that it can be moved horizontally into a desired contact-making end position . For this, the contactor corresponds to the cross section of the external shape of the Rack element, which is also arranged in the profile groove. With preferred positioning of the contactor at the respective ends of the toothed rack element, the fastening for blocking in the longitudinal direction takes place by means of fastening means, preferably fastening screws.

A secure and cost-effective connection of the contact point between the contactor and the contact lug is achieved by arranging resilient contact plates in the groove of the contactor, which are connected to the power source by means of a connected power line that transmits electrical current.

In addition, the contactor attached to the window frame enables the lift-and-slide sash to be braked and/or stopped in one of the end positions of the closed or open position in a damping manner when the contact lug moves into the groove of the contactor, with the contact plates being designed as buffers or as a reference signal transmitter for positioning are used.

The contact lug designed as a pin or bridge proves to be inexpensive to manufacture, easy to assemble and with a stable structure for a long service life. The contact lug is designed as a contact point as a whole or at least with a partial section. The lift-and-slide sash is retracted into the locked closed position with vertical contact with the window frame, with the contact lug making contact between the contact plates of the contactor and establishing an electrical connection between the lift-and-slide sash and the window frame with virtually no friction, by shaping and selecting the material of the contact lug and the contactor.

At least one carriage is formed on the side of the housing of the drive device facing the guide rail for slidingly connecting the drive device and for moving the sash relative to the frame in the longitudinal direction of the guide rail. With the arrangement of the carriage above the thread of the threaded spindle and the interaction of the threaded spindle of the motor drive with the toothed segments of the rack element, the carriage is slidably carried in a T-shaped guide groove of the rack element.

A drive device that is compact and concealed in the window of the door is achieved in that the contact lug for the electrical contact point is designed to be adapted in cross section to the vertical section of the T-shaped open guide groove. In addition, the contact lug remains constantly displaceable during lowering of the wing or to compensate for tolerances in the guide groove. A contact between the guide groove and the contact lug remains intact. Good sliding properties with low frictional resistance are achieved by the contact lug in a movable operative connection with the guide groove of the toothed rack element through a shape rounded at the edges and through a corresponding choice of material to one another.

For easy assembly of the components belonging to the drive device, the drive device with the drive motor is detachably fixed in the receiving groove in the movable lift-and-slide sash. For this purpose, the respective longitudinal ends of the housing of the drive device enter into a positive and/or non-positive connection with the limiting and fastening part fastened to the wing. The housing, together with the wing-side components of the drive device, is inserted as a one-piece component from an end of the upper horizontal spar that is open on the face side of the movable wing into the recess or receiving groove.

A correctly movable sequence of the lifting and sliding sash to the window frame is achieved after manual or automatic switching specification, so that the drive device arranged displaceably on the window frame enters into a horizontally fixed position with the movable sash. This enables a horizontal adjustment of the sash from a closed position to an open position. In addition, the sash can be transferred to the frame in a locked closed position and transported from the locked closed position to a raised position for sliding. When raising the wing and removing it from the running rail or lowering the wing onto the running rail, the limiting and fastening parts attached to the upper horizontal spar in the receiving groove slide without resistance along the lateral end faces of the drive device. In a particularly advantageous manner, the end of the drive device and the limiting part fastened to the movable lifting/sliding sash each have a connecting contact point which is suitable for transmitting an electric current, starting from a power source arranged on a building wall, for charging an accumulator. In addition, while the lifting and sliding sash is being moved, the power supply remains reliable, which is also provided by the accumulator with the delivery of power to the drive device via the same contact points.

With an advantageously small distance between all functional components and the receiving grooves provided within the movable leaf, the supply lines can be concealed and installed in the window or door. For this purpose, all contact points form a connecting chain of transmission of the electric current to the individual functional components by control and/or power lines, starting from the power source to the drive device and on to the accumulator. The contact points are positioned between the individual functional components. The contact and the stored current of the accumulator are thus also transmitted to the drive motor during the active movement of the wing when raising, lowering or shifting. With the arrangement of the functional components in the receiving groove, the control and/or power lines preferably run in a concealed manner in the receiving groove. The contact points bridge the power and control supply within the receiving groove of the movable sash and from the sash to the frame for the power line in the direction of the power source. The voltage always has the same sign on bus participants such as the battery pack, lifting and sliding drives. However, depending on the situation, the motors are variably supplied with electricity. The drive device can usually be installed in the window or door without additional cutouts, since the cutouts are generally used for functional components.

The embodiment for the transmission of the electrical current and/or signals in which the contact points are in the form of sliding contacts has proven to be simple and cost-effective. The sliding contact is particularly suitable for special requirements where cables can be routed between rigid and moving parts. The spring-like contacts allow both vertical and horizontal smooth running with the greatest possible contact reliability. The spring contacts are made of a spring sheet metal so that they do not corrode, which ensures reliable contact even with small currents and voltages. Other variants such as plug contacts or plunger contacts are also possible.

For easy assembly, the delimiting part is fastened in the recess or receiving groove, preferably with a non-positive fit by means of a fastening screw. On the other hand, the fastening part arranged pointing to the vertical spar of the lifting/sliding sash is supported with a first section on the upper horizontal spar in the recess or receiving groove. A second section engages in a vertical receptacle of the vertical beam in a form-fitting manner and preferably forms a non-positive connection with the lift-and-slide sash by means of a fastening screw.

Compensating for vertical adjustment of the movable sash to the frame, for example to lower the sash from a closed position to a locked position or to raise the sash from a locked position of the sash to the frame into a raised and horizontally displaceable position of the sash, is the section of the fastening part stored vertically leading on the side of the housing facing the drive motor.

For simplified assembly and cost-effective production of the drive device is on the to the free end of the upper horizontal strut arranged fastening part arranged transversely in the direction of the guide rail and spaced from the recess or receiving groove of the movable wing ball bearing roller. The roller is slidably mounted in laterally arranged transverse guides of the guide rail. Likewise, a further roller is preferably provided at the other end of the upper horizontal bar, which is positively and / or non-positively attached to the wing. The rollers attached to the sash contribute to a secure sliding hold of the upper horizontal area of the movable sash to the frame. Instead of ball-bearing rollers, height-adjustable sliders or other components can also be used to guide the sash.

In connection with the drive device with the toothed rack element bound positively in the guide rail via the threaded spindle as the transmission component of the drive motor and via the carriage as the supporting component, this results in simple assembly and undemanding connection of the window frame to the movable lift-and-slide sash. When the movable sash is already installed in the window frame, the movable sash is moved via the lower carriage on the running rail leading to the drive device or the drive device itself is moved to the movable sash in the interaction of the threaded spindle and the toothed rack element until the drive device is completely concealed in the receiving groove the delimiting part strikes with a first front end. The end position in the movable wing for the drive device has thus been reached. A completely non-displaceable position of the drive device in the horizontal direction is realized by the fastening part, which is arranged at the other open end of the receiving groove and positions the second front end of the drive device.

With a further advantageous embodiment variant of the drive device, the limiting part arranged on the wing has an adapter element and the fastening part, which is also fastened to the wing, has an adapter element. The adapter elements form an effective connection between the delimiting part and the fastening part to the housing of the drive device, so that the drive device can be displaced in a desired manner in a vertical direction while maintaining the position horizontally. Also conceivable for a horizontal hold of the drive device on the sash during horizontal movement of the sash to the frame and vertical movement of the sash for lowering into the closed position or for lifting in a guided sliding movement towards the frame is a hole in the drive device and a hole guided in the hole Bolt attached to the wing.

A functional connection between the drive device arranged on the window frame and bridging to the components arranged on the sash results simply and inexpensively. For this purpose, grooves are formed on the longitudinal ends of the housing, with the adapter elements having webs which form complementary leads and which can slide in the grooves.

To bridge the power and control supply, the adapter element accepts a plug-in circuit board in a positive and/or non-positive manner. For this purpose, the adapter element is designed with a U-shaped cross section for a position of the plug-in circuit board that can be positioned.

The adapter element and the delimiting part form a one-piece component. The limiting part consists of a housing which accommodates an adapter circuit board, a plug contact for the contact of the control line and a circuit board connector for the transmission to the plug-in circuit board for the contact lug.

For easy assembly and connection of the drive device essential components that form the coupling from the window frame to the sash and produce the bridging contact of the power and control supply, the adapter element and the fastening part are designed as a one-piece component. For this purpose, the fastening part has a horizontal and vertical section, the horizontal section having a web which engages in a fixed position in a receiving groove arranged on the adapter element.

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 1 shows a perspective view of a window or a door 3, a window frame 4 with a sliding wing 2 and a fixed wing or

Door panel 60 adjacent to this. To actuate the movable wing 2 , an operating element 61 with a switch is provided on a vertical strut 62 , which controls a drive device 1 . By actuating the operating element 61, the movable leaf 2, for example from the 1 having closed position in a corresponding to the direction of the arrow, not shown position relative to the fixed window frame 4 and the stationary mounted wing or door panel 60, but on the other hand bring it into a secured shifted ventilation position or an area of a passage opening. The wing 2 is hanging over one or more or after 1 bottom-side having carriage 65 supported on a rail 64 on the frame 4 held movable.

Operating the drive device 1 via a remote control unit or a smart home system is also conceivable. For this purpose, a radio system is provided in the wall, with the control units being distributed over the drive components in wing 2 . Likewise, at the window or the door 3 after 1 a power source 16 and, if necessary, a control unit 67 can be provided. The power source 16 and the control unit 67 can also be accommodated in a wall of a building 43 and are connected to the operating element 61 and the drive device 1 via control and/or power lines 44 .

The operating element 61 can also control a drive 66, shown schematically in the closing direction at the front of the vertical beam 62, which also on the vertical beam 62--not shown--transfers locking means into a locked closed position or into an unlocked open position of the leaf 2. Manual actuation by means of an actuation handle with transmission of an actuation linkage to the locking means is also conceivable.

In a system of a displaceable lift-and-slide sash 2 of a window or a door 3, the movable sash 2 can be automatically driven by the drive 66 shown schematically via the operating element 61 or via the manual operating handle from the 1 having closed position by a coupled connection of the actuating linkage to the carriage 65 in a raised open position in order to then be moved by the drive device 1 can.

Likewise, both 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 and/or power lines 44 and linked to the power source 16 and the control unit 67 .

So that these positions of the wing 2 are possible relative to the fixed frame 4 and to the fixed wing or to the fixed door panel 60, a special fitting arrangement is installed between the movable wing 2 and the fixed frame 4, namely a so-called system for sliding sashes or movable lifting Sliding sash provided by which in the 1 for the sake of simplicity, only the operating element 61 on the wing 2, a part of a lower rail 64 for the carriage 65 and an upper guide rail 10 after 7 can be hinted at.

After 6 the drive device 1 comprises a drive motor 5 with a threaded spindle 6 driven thereon. The threaded spindle 6 is after 4 and 5 positively guided around a toothed rack element 7 arranged on the window frame 4 . To 2 is the drive device 1 in the installed position of the wing 2 almost completely in a recess or receiving groove 8 of an upper, horizontal beam 9 of the movable wing 2 and arranged on the frame 4 guide rail 10 is arranged lying covered. The drive motor 5 and the threaded spindle 6 are after 6 stored as a structural unit forming in a housing 11. The rack element 7 is after 7 almost completely surrounded by a guide cross section of the guide rail 10 that forms a support. A gap in the guide rail 10 forms an opening 51 and thus the possibility of coupling between the components arranged on the wing 2 and the components of the drive device 1 mounted on the frame 4. The drive motor 5 and the threaded spindle 6 are after 6 coupled in the longitudinal direction to the direction of displacement of the wing 2 for a rotational transmission of the movement by a tooth transmission drivingly connected.

The movable wing 2 comprises four spars, which are designed as hollow profiles, in particular as aluminum or plastic profiles or as solid profiles consisting of wood. The struts, like the struts 9, 23, 62 and 63 described, contain prefabricated recesses or receiving grooves for concealed mounting of fitting components. Thus, the drive device 1 is provided in the upper horizontal beam 9 in the receiving groove 8, which is arranged to the vertical beam 23 directed. Preferably, the wing-side components of the drive device 1, in particular the housing 11, after 7 adapted to the height H and the width B of the recess or receiving groove 8 of the upper horizontal bar 9 of the wing 2 . Additional work steps for mounting the drive device 1 on the wing 2 are therefore omitted.

To the in the guide rail 10 movably bound drive device 1 with the movable wing 2 releasably fixed in the receiving groove 8 after 2 and 3 easy to connect, go the respective longitudinal ends 19, 20 after 2 and 6 of the housing 11 a functional connection, fixed horizontally to the direction of displacement, with the limiting and fastening parts 21, 21' fastened to the wing 2; 22, 22'a.
