Description

The invention relates to a door or window with a sliding sash as a sliding sash or a sliding lifting-sliding sash, a frame in which the sash is slidably held, 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 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 also proven to be complex from the known prior art.

Furthermore, concealed drives are known which, however, can only be integrated with great effort and in less suitable profile systems. In particular, the milling effort in the profile turns out to be very high and can lead to high costs and to a weakening of the structure of the window or door elements.

Furthermore, a power transmission in sliding door systems of this type usually takes place by means of a belt drive which requires additional components and must be taken into account from the outset when designing and constructing a sliding door system. Retrofitting manual sliding door systems with motorized drives is therefore not possible with the drive solutions known up to now, or only at great expense.

In addition, the drives usually include an interface by means of which electrical energy and / or control signals can be fed into the drive in a wired manner. A direct wired connection for the motorized operation is complex to assemble and requires additional assembly space. Millings in the sash or frame are possible.

In order to be able to do this, you need special tools, a high expenditure of time and special technical skills. A wired variant is therefore complex to assemble 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, the current transmission being generated via so-called spring-loaded tappet contacts. These are arranged on the end face of the sash on the locking side, when the sash is closed in the locked position, they meet a corresponding counterpart contact in the frame and thus establish a connection to a power supply. The known arrangement of the contact counterpart can only be installed depending on a fixed installation point, for example on a vertical frame spar. A system of a window or a door with sashes running against each other to close cannot be implemented with the known system. In addition, a concealed arrangement of the counterpart contact on the frame is also only possible with complex millings in the vertical frame spar, which has a disadvantageous effect on the assembly and also on the costs.

Well known is the WO 2014/097211 A1 which has a door or window with a sliding sash as a sliding sash or a sliding lift-and-slide sash, a frame in which the sash is slidably held and a drive device. For moving the sash, the drive device comprises a drive motor arranged on the frame side with a threaded spindle driven on it. The threaded spindle is forcibly guided around a 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 has a bevel gear that translates the rotation of the motor shaft about a horizontal axis into a rotation of a shaft about a vertical axis. The shaft drives a pinion that meshes with the rack member. The carriage of the sliding door is designed such that the upper horizontal spar of the wing and the guide rail are spaced apart from one another in the vertical direction. The drive device also has a power supply. For this purpose, the power supply is arranged outside the sliding device and continuously supplies a power supply conductor arranged over the entire length of the running rail with current, which is operatively connected to a current collector on the carriage and which drives the electric motor. Of 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 very quickly and lead to a recurring problem up to 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 lifting-sliding sash for large portability and optimal guidance for a window or door is provided at low cost and little installation space, which also can be retrofitted and adjusted in a simple, fast, safe and precise manner , as well as can be dismantled.

This object is achieved by a door or window with a sliding sash as a sliding sash or a sliding lift-and-slide sash, a frame in which the sash is slidably held and a drive device with the features of claim 1.

The drive device 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 a door. 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 extent 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 leaf can be moved, for example, from a closed position into a leaf or door panel that is fixed opposite a fixed frame and a fixedly mounted leaf. 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. The control unit can be accommodated in the 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 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 sliding lift-and-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, in order to subsequently 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 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 are possible relative to the fixed frame as well as 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.

In an advantageous manner, the drive device for moving the wing comprises a drive motor arranged on the wing side with a threaded spindle driven thereon. The threaded spindle is forcibly guided around a rack element arranged on the frame. A concealed arrangement of the drive device is made possible by the fact that the drive device is almost completely mounted in the installation position of the movable sash in a recess or receiving groove of an upper, horizontal spar of the movable sash and a guide rail arranged on the frame. For an optimal mounting of the drive components of the drive device, the drive motor and the threaded spindle are mounted as one structural unit in a housing. The rack element is almost completely encompassed by the guide rail. The receiving groove on the upper horizontal spar of the movable wing 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 are drive-connected for a rotational transmission of the movement by means of a gear transmission, a positive connection of a flexible shaft or a cardan in the longitudinal direction to the direction of displacement of the sash, proves to be cost-effective and structurally advantageous.

The movable wing comprises four spars, which are designed as hollow profiles, in particular as aluminum or plastic profiles or as solid profiles consisting of wood. The spars contain prefabricated recesses or receiving grooves for the concealed installation of fitting components, in particular for the drive device. Thus, the drive device is mounted in a recess or receiving groove in the upper horizontal spar and facing the vertical spar. 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 not required.

Thus, an accumulator is advantageously mounted on the lifting-sliding sash, which is in continuous electrical contact with the drive device while the movable sash is moving or when the sash is at rest. In a resting position, for example in the closed position or in a locked position, the movable sash receives power bridging the frame via a contactor with a contact point in the extension of the rack element, from a power source arranged on the 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-slide sash is horizontally displaced by the electric drive motor and closes the contact for a current flow when it is retracted. To enable the electrical contact to be made between the contactor and the contact tab, 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 bar of the lift and slide sash near the drive motor. This ensures a secure power supply through 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 in a concealed manner in the window or door.

A simple assembly and a simple assembly of the contactor, which forwards the transmission of the electrical current from the power source to the drive components, is thus made possible that the contactor is held vertically in a profile groove of the guide rail, but is joined horizontally in 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 the preferred positioning of the contactor at the respective ends of the rack element, the fastening for a blocking in the longitudinal direction takes place by means of fastening means, preferably by fastening screws.

A secure and inexpensive connection of the contact point between the contactor and the contact lug is achieved in that resilient contact plates are arranged in the groove of the contactor and are connected to the power source by means of a connected power line.

In addition, the contactor attached to the frame allows the lifting and sliding sash to be braked and / or stopped in a damping manner in one of the end positions of the closed or open position when the contact lug moves into the groove of the contactor, whereby the contact plates are designed as buffers or as reference signal transmitters Position determination can be used.

The contact tab, which is designed as a pin or web, has proven to be inexpensive to manufacture, easy to assemble and with a stable structure for a long service life. The contact tab is designed as a whole or at least with a partial section as a contact point. The lifting and sliding sash is retracted into the locked closed position with vertical contact with the frame, whereby the contact tab enters between the contact plates of the contactor and an electrical connection between the lifting and sliding sash and the blind frame is established with almost no friction due to the shape and material selection of the contact tab and the contactor.

For the sliding connection of the drive device and for a movable displacement of the sash to the frame in the longitudinal direction of the guide rail, at least one carriage is formed on the side of the housing of the drive device facing the guide rail. With the carriage above the thread of the With the threaded spindle and the interaction of the threaded spindle of the motorized drive with the toothed segments of the rack element, the carriage is slidably supported in a T-shaped guide groove of the rack element.

A compact and concealed drive device arranged in the window of the door is achieved in that the contact tab for the electrical contact point is designed to shape the vertical section of the T-shaped open guide groove in cross-section. In addition, the contact lug remains constantly displaceable in the guide groove while the sash is being lowered or to compensate for tolerances. Contact between the guide groove and the contact lug remains constant. The contact lugs achieve good sliding properties with low frictional resistance in a movable operative connection with the guide groove of the rack element through a shape rounded at the edges and through the appropriate choice of materials.

For simple assembly of the components belonging to the drive device, the drive device with the drive motor is releasably fixed in the receiving groove in the movable lift-slide sash. For this purpose, the respective longitudinal ends of the housing of the drive device enter into a form-fitting and / or force-fitting connection with the limiting and fastening part attached to the wing. The housing is inserted together with the wing-side components of the drive device as a one-piece component from an end of the upper horizontal spar that is open at the front of the movable wing into the recess or receiving groove.

A correctly movable sequence of the lift-slide sash to the frame is achieved according to manual or automatic switching specification, so that the drive device arranged displaceably on the frame adopts a position fixed in the horizontal direction with the movable sash. This enables the sash to be adjusted horizontally from a closed position to an open position. In addition, the sash can be transferred to the frame in a locked closed position and moved from the locked closed position into a raised position for displacement. When lifting 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 attached to the movable lift-slide sash each have a connecting contact point, which are suitable for transmitting an electrical current, starting from a power source arranged on a building wall for charging to an accumulator. In addition, while the lift and slide sash is being moved, the power supply is reliably maintained, which is also provided by the accumulator with the delivery of current to the drive device via the same contact points.

With an advantageously small distance between all functional components and provided grooves within the movable sash, the supply lines can be installed in a concealed manner in the window or door. For this purpose, all contact points form a connecting chain of transmission of the electrical current to the individual functional components by means of 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.

Likewise, the contact and the stored current of the accumulator are transferred to the drive motor during the active movement of the wing when it is raised, lowered or moved. With the arrangement of the functional components in the receiving groove, the control and / or power lines preferably run concealed 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 to the power line in the direction of the power source. At bus participants such as Battery pack, lifting and sliding drive always receives the voltage with the same sign. However, the motors are supplied with power depending on the situation. 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 design for the transmission of the electrical current and / or signals that the contact points are designed as sliding contacts has proven to be simple and inexpensive. 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 security. The spring contacts are made from a spring sheet, which is corrosion-free, which ensures reliable contact even with small currents and voltages. Other variants such as plug-in contacts or tappet contacts are also possible.

For simple assembly, the delimitation part is fastened in the recess or receiving groove, preferably by a fastening screw, with a force fit. That to the vertical spar of the Fastening part arranged facing the lift-slide sash, however, 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 spar in a form-fitting manner and, preferably by means of a fastening screw, enters into a force-fitting connection with the lift and slide sash.

The section of the fastening part compensates for vertical adjustment of the movable sash to the frame, for example to lower the sash from a closed position into 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 mounted vertically leading on the side of the housing facing the drive motor.

For simplified assembly and cost-effective manufacture of the drive device, a ball-bearing roller is arranged on the fastening part arranged at the free end of the upper horizontal spar, transversely in the direction of the guide rail and spaced from the recess or receiving groove of the movable wing. 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 spar, which is attached to the wing with a positive and / or non-positive fit. The rollers attached to the sash contribute to a secure, displaceable hold of the upper horizontal area of the movable sash to the frame. To guide the sash, height-adjustable sliding pieces or other components can also be used instead of ball-bearing rollers.

In connection with the drive device with the rack element positively bound in the guide rail via the threaded spindle as the transmission component of the drive motor and via the slide as the load-bearing component, simple assembly and undemanding connection of the frame to the movable lift and slide sash results. In the already installed state of the movable sash to the 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 in the interaction of the threaded spindle and the rack element to the movable sash until the drive device lies completely concealed in the receiving groove the limiting part strikes with a first front end. The end position in the movable wing for the drive device is thus reached. A completely non-displaceable position of the drive device in the horizontal direction is achieved by the fastening part which, arranged at the other open end of the receiving groove, positions the second end face 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 delimitation part and the fastening part to the housing of the drive device, so that the drive device can only be moved in a vertical direction in the desired manner while maintaining the horizontal position. A hole in the drive device and one in the hole are also conceivable for a horizontal hold of the drive device on the sash when the sash moves horizontally towards the frame and when the sash moves vertically to lower it into the closed position or to lift it in a guided sliding movement towards the frame Bolt that is attached to the wing.

A functional connection between the drive device arranged on the frame and bridging to the components arranged on the sash results in a simple and cost-effective manner. For this purpose, grooves are formed on the longitudinal ends of the housing, the adapter elements having complementary webs leading to them which can slide in the grooves.

In order to bridge the power and control supply, the adapter element accepts a plug-in board with a positive and / or non-positive fit. For this purpose, the adapter element for a positionable position of the plug-in circuit board is U-shaped in cross section.

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

The adapter element and the fastening part are designed as a one-piece component for simple assembly and connection of the drive device, which are essential components that form the coupling between the frame and the sash and establish the bridging contact of the power and control supply. 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.
