EP4176150B1 - Door or window having a displaceable wing in the form of a sliding wing or displaceable lifting/sliding wing and having a drive device - Google Patents

Description

The invention relates to a door or window with a sliding wing as a sliding wing or sliding lift-sliding wing, a frame in which the wing is held so that it can move, and a drive device for the sliding door system according to the preamble of claim 1.

The sliding sashes of systems such as sliding sashes or lift-slide sashes for a window or door often have a relatively high mass. When the sash is moved, especially when it is pushed from a standing position, a high force must be applied to open it. Closing also requires resistance to the weight of the sash. Conventional drives are visibly mounted on the window or door and are shielded with an additional cover, which greatly impairs the appearance. The risk of injury during installation is also increased by visible components that are inconveniently placed on top. Visible components also offer more opportunities for manipulation from the outside. Installing such a drive device is also complex based on the current state of the art.

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

Furthermore, power transmission in such sliding door systems is usually carried out 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 motor drives is therefore not possible with the drive solutions known to date, or only possible 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 cable. A direct cable connection for motor operation is complex to install and requires additional installation space. Milling out the sash or frame is possible. To do this, special tools, a lot of time and specialist skills are required. A wired version is therefore complex to install and is 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 tappet contacts. These are arranged on the locking-side face of the sash, meet a corresponding contact counterpart in the arranged frame when the sash is closed in the locked position and thus establish a connection to a power network. The known arrangement of the contact counterpart can only be mounted depending on a fixed mounting point, for example on a vertical frame beam. A system of a window or a door with wings running against each other for closing cannot be realized with the known system. In addition, a concealed arrangement of the contact counterpart on the frame is also only possible with complex milling in the vertical frame beam, which has a detrimental effect on assembly and also on costs.

The well-known WO 2014/097211 A1 , which has a door or window with a sliding wing as a sliding wing or sliding lift-sliding wing, a frame in which the wing is held so that it can move, and a drive device. The drive device comprises a drive motor arranged on the frame side with a threaded spindle driven on it for moving the wing. The threaded spindle is positively guided around a rack element arranged on the wing. The drive motor and the threaded spindle are mounted in a housing to form a structural unit.

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 beam of the wing and a rack element 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 is in engagement with the rack element. 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 each other in the vertical direction. The drive device also has a power supply. The power supply is arranged outside the sliding device and continuously supplies a Power supply conductor with electricity that is operatively connected to a current collector on the carriage 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 or even 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 load-bearing capacities and optimal guidance for a window or door is provided at low cost and in a small installation space, which can also be subsequently installed, adjusted and dismantled in a simple, quick, safe and precise manner.

This object is achieved by a door or window with a movable sash as a sliding sash or movable lift-sliding sash, a frame in which the sash is held so that it can move, 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 sliding sash as a sliding sash or a sliding lift-sliding sash for a window or a door. The movable sash has at least two carriages, each with rollers, in order to be moved on a guide rail in a direction parallel to the extension of the sash or along a guide rail. For automatically movable operation of the sash, an operating element with a switch is preferably provided on a vertical beam, which controls a drive device. By operating the operating element, the movable sash can be moved, for example, from a closed position to one opposite a fixed frame and a fixedly mounted sash or door panel. On the other hand, the sash can also be brought into a secure, displaced ventilation position or an area of a passage opening. The sash is advantageously held so that it can be moved on the frame via carriages on the floor side, supported on a guide rail.

It is also possible to operate the drive device using a remote control unit or a smart home system. For this purpose, a control unit is provided on the window or door. The control unit can be housed 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 arranged at the front of the vertical beam in the closing direction, which also moves locking means on the vertical beam into a locked closed position or into an unlocked open position of the wing. Manual actuation by means of an actuating handle with transmission of an actuating rod to the locking means is also conceivable.

In a system of a sliding lift-sliding sash of a window or 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 rod to the carriages into a raised opening position in order to then be able to be moved by the drive device.

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

In order to make these positions of the sash 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 sashes or sliding lift-sliding sashes, is provided between the movable sash and the fixed frame.

The drive device for moving the sash advantageously comprises a drive motor arranged on the sash side with a threaded spindle driven thereon. The threaded spindle is positively 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, in the installed position of the movable sash, is almost completely mounted in a recess or receiving groove of an upper, horizontal beam of the movable sash 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 in a housing as a structural unit. 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 ends 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 by a gear transmission, a positive connection of a flexible shaft or a cardan in the longitudinal direction to the direction of displacement of the wing.

The movable sash comprises four spars, which are designed as hollow profiles, in particular as aluminum or plastic profiles or as solid profiles made of wood. The spars contain prefabricated recesses or receiving grooves for the concealed installation of fitting components, in particular for the drive device. The drive device is mounted in a recess or receiving groove in the upper horizontal spar and facing the vertical spar. The sash-side components of the drive device are preferably designed to match the height H and width B of the recess or receiving groove of the upper horizontal spar of the sash. Additional work steps for mounting the drive device on the sash are therefore not necessary.

For example, an accumulator is advantageously mounted on the lift-slide 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 this case, the movable sash, in a resting position, for example in the closed position or in a locked position, receives current bridging the frame via a contactor with a contact point that is an extension of the rack element and 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 in the contactor when the lift-slide sash is moved horizontally by the electric drive motor, and closes the contact for current flow when it is retracted. To enable electrical contact to be made between the contactor and the contact lug, the groove is open for retraction towards the sash.

In a preferred embodiment, the accumulator, or battery for short, is concealed in the receiving groove of the upper, horizontal beam of the lift-slide sash close to 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 concealed in the window or door.

A simple assembly and installation 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 can be moved horizontally into a desired contact-making end position. For this purpose, 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 rack element, the fastening for blocking in the longitudinal direction is carried out by means of fastening means, preferably by fastening screws.

A safe and cost-effective connection of the contact point between the contactor and the contact lug is achieved by arranging spring-loaded contact plates in the groove of the contactor, which are connected to the power source by means of a connected control line to transmit electrical current.

In addition, the contactor attached to the frame allows the lift-slide sash to be braked and/or stopped in one of the end positions of the closed position by inserting the contact lug into the groove of the contactor, with the contact plates being designed as buffers.

The contact lug, designed as a pin or web, is inexpensive to manufacture, easy to install and has a stable structure for a long service life. The contact lug is designed as a whole or at least with a partial section as a contact point. The lifting/sliding sash is moved into the locked position with a vertical position to the frame, whereby the contact lug moves against the contact plates of the contactor and establishes an electrical connection between the lifting/sliding sash and the frame with almost no friction. This is achieved by the shape and choice of material of the contact lug and the contactor.

To ensure a sliding connection of the drive device and to allow the sash to be moved to the frame in the longitudinal direction of the guide rail, at least one slide is formed on the side of the housing of the drive device facing the guide rail. With the slide arranged 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 slide is slidably supported in a T-shaped guide groove of the rack element.

A compact drive device that is concealed in the window of the door is achieved by the contact lug for the electrical contact point being designed in a cross-section that is shaped to fit the vertical section of the T-shaped guide groove. The contact lug is therefore guided in the guide groove in a sliding horizontal direction when the leaf is moved. In addition, the contact lug remains in place during a The guide groove can be constantly moved when the wing is lowered or to compensate for tolerances in the guide groove. There is constant contact between the guide groove and the contact lug. The contact lug in a movable connection with the guide groove of the rack element achieves good sliding properties with low frictional resistance through a rounded shape at the edges and through the appropriate choice of materials.

To facilitate the assembly of the drive device components, the drive device with the drive motor is detachably fixed in the receiving groove in the movable lifting/sliding sash. To this end, the respective long ends of the housing of the drive device form a positive and/or non-positive connection with the limiting and fastening part attached to the sash. The housing, together with the sash-side components of the drive device, is inserted into the recess or receiving groove from an end of the upper horizontal beam that is open on the front side of the movable sash, forming a single part.

A correctly movable movement of the lifting/sliding sash to the frame is achieved according to manual or automatic switching instructions, so that the drive device arranged so as to be movable on the frame enters a horizontally fixed position with the movable sash. This enables horizontal adjustment of the sash from a closed position to an open position. In addition, the sash can be transferred to the frame into a locked closed position and from the locked closed position to a raised position for sliding. When the sash is lifted and removed from the guide rail or the sash is lowered onto the guide rail, the limiting and fastening parts attached to the upper horizontal beam 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 lifting/sliding sash each have a connecting contact point, which are suitable for transmitting an electrical current from a power source arranged on a building wall to a battery for charging. In addition, the power supply remains reliable during the movement of the lift-sliding wing, which is also carried out by the accumulator with the supply of current to the drive device via the same contact points.

With the advantageously small distance between all functional components and the provided mounting grooves within the movable wing, the supply lines can be installed concealed in the window or door. For this purpose, all contact points form a connecting transmission chain of the electrical current to the individual functional components through control and/or power lines, starting from the power source to the drive device and further to the Accumulator. The contact points are positioned between the individual functional components. The contact and the stored current of the accumulator are also transferred to the drive motor during the active movement of the sash when raising, lowering or moving. When the functional components are arranged 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. The electrical current also flows in the opposite direction as required. The drive device can usually be installed in the window or door without additional milling, as the milling is generally used for functional components.

The design for the transmission of electrical current and/or signals is simple and cost-effective, as the contact points are designed as sliding contacts. The sliding contact is particularly suitable for special requirements where a cable can be routed between rigid and moving parts. The spring-shaped contacts allow smooth vertical and horizontal running with the greatest possible contact reliability. The spring contacts are made from a corrosion-free spring sheet, which ensures reliable contact even with small currents and voltages. Other variants such as plug contacts or plunger contacts are also conceivable. However, these can have a negative impact on costs.

For easy installation, the limiting part is preferably fastened in the recess or receiving groove with a fastening screw. The fastening part arranged facing the vertical beam of the lifting/sliding sash, on the other hand, is supported with a first section on the upper horizontal beam in the recess or receiving groove. A second section engages in a vertical receptacle of the vertical beam with a positive fit and forms a force-fitting connection with the lifting/sliding sash, preferably with a fastening screw.

To compensate for vertical adjustment of the movable sash in relation 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 in relation to the frame into a raised and horizontally movable position of the sash, the section of the fastening part is mounted in a vertically guiding manner on the side of the housing facing the drive motor.

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

The connection of the drive device with the rack element, which is positively connected in the guide rail, via the threaded spindle as the transmission component of the drive motor and via the carriage as the load-bearing component, results in simple assembly and undemanding connection of the frame to the movable lift-slide sash. When the movable sash is already installed in the frame, the movable sash is moved to the drive device via the lower carriages on the guide rail, or the drive device itself is moved to the movable sash in interaction with the threaded spindle and the rack element until the drive device, completely concealed in the receiving groove, hits the limiting part with a first front end. The end position in the movable sash for the drive device is thus reached. A completely displacement-proof position of the drive device in the horizontal direction is achieved 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.

Preferred 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 movable wing 2 and a fixed wing or door panel 60 which is adjacent to it. To operate the movable wing 2, an operating element 61 with a switch is provided on a vertical beam 62, which controls a drive device 1. By operating the operating element 61, the movable wing 2 can be moved, for example from the position shown in Fig.1 The wing 2 can be moved from a closed position in the direction of the arrow to a position not shown in relation to the fixed frame 4 and the fixedly mounted wing or door panel 60, but can also be moved to a secured, displaced ventilation position or to an area of a passage opening. The wing 2 is thereby connected to one or more hanging or Fig.1 The carriage 65 on the floor is supported on a guide rail 64 and held movable on the frame 4.

It is also possible to operate the drive device 1 via a remote control unit or a smart home system. For this purpose, the window or door 3 must be Fig.1 a power source 16 and, if necessary, a control unit 67. The power source 16 and the control unit 67 can also be accommodated in a wall of a building 43 and is 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, which is shown schematically at the front of the vertical beam 62 in the closing direction and which also transfers locking means (not shown) on the vertical beam 62 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 rod to the locking means is also conceivable.

In a system of a sliding lifting-sliding sash 2 of a window or a door 3, the movable sash 2 can be moved automatically by the schematically illustrated drive 66 via the operating element 61 or via the manual operating handle from the position shown in the Fig.1 having a closed position by means of a coupled connection of the actuating rod to the carriages 65 into a raised opening position in order to be able to be subsequently displaced by the drive device 1.

Likewise, both of the above-described actuation variants can be arranged in a window or a door 3, which can be selected according to 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.

In order to enable these positions of the wing 2 relative to the fixed frame 4 and to the fixed wing or the fixed door panel 60, a special fitting arrangement is provided between the movable wing 2 and the fixed frame 4, namely a so-called system for sliding wing or sliding lift-sliding wing, of which Fig.1 For the sake of simplicity, only the operating element 61 on the wing 2 is part of a lower guide rail 64 for the carriages 65 and an upper guide rail 10 according to Fig.7 can be seen in a vague way.

After Fig.6 The drive device 1 comprises a drive motor 5 with a threaded spindle 6 driven thereon. The threaded spindle 6 is Fig. 4 and Fig. 5 by a rack element 7 arranged on the frame 4. After Fig.2 the drive device 1 is arranged in the installed position of the sash 2 almost completely concealed in a recess or receiving groove 8 of an upper, horizontal beam 9 of the movable sash 2 and a guide rail 10 arranged on the frame 4. The drive motor 5 and the threaded spindle 6 are arranged according to Fig.6 as a structural unit in a Housing 11. The rack element 7 is Fig.7 almost completely surrounded by a guide cross-section of the guide rail 10, which 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 sash 2 and the components of the drive device 1 mounted on the frame 4. The drive motor 5 and the threaded spindle 6 are Fig.6 coupled in a drive-connected manner in the longitudinal direction to the direction of displacement of the wing 2 for a rotational transmission of the movement by means of a tooth transmission.

The movable wing 2 comprises four spars, which are designed as hollow profiles, in particular as aluminum or plastic profiles or as solid profiles made of wood. The spars, such as the described spars 9, 23, 62 and 63, contain prefabricated recesses or receiving grooves for the concealed installation of fitting components. The drive device 1 is provided in the upper horizontal spar 9 in the receiving groove 8, which is arranged facing the vertical spar 23. Preferably, the wing-side components of the drive device 1, in particular the housing 11, are according to Fig.7 in height H and width B adapted to the recess or receiving groove 8 of the upper horizontal spar 9 of the wing 2. Additional work steps for mounting the drive device 1 on the wing 2 are therefore not necessary.

In order to move the drive device 1 movably bound in the guide rail 10 with the movable wing 2 releasably fixed in the receiving groove 8 according to Fig. 2 and Fig. 3 easy to connect, the respective longitudinal ends 19, 20 go to Fig.2 and Fig.6 of the housing 11 forms a functional connection, which is fixed horizontally to the direction of displacement, with the limiting and fastening parts 21, 22 fastened to the sash 2. The housing 11, together with the sash-side components of the drive device 1, is inserted from an open end 34 of the upper horizontal beam 9 of the sash 2 into the recess or receiving groove 8 manually or automatically by means of the spindle drive. The sash 2 can also be moved towards the drive device 1 until the limiting part 21 rests against the end 19 of the housing 11. In the assembled state, the end 19 of the housing 11 forms a horizontally fixed connection with the limiting part 21, which is force-fitted in the recess or receiving groove 8 by a fastening screw. While maintaining the position of the drive device 1 in the horizontal direction or displacement direction of the wing 2, the limiting part 21 can be moved vertically relative to the end 19 of the drive device 1 with adjustment of the wing 2 for lifting or lowering. Fig.2 shows a lowered position of the sash 2 relative to the frame 4, wherein the drive device 1 is spaced from the bottom of the receiving groove 8.

At the end of the vertical beam 23 of the upper horizontal beam 9 facing the movable wing 2 after Fig.2 and Fig.6 a ball-bearing roller 25 is arranged in the receiving groove 8 on the fastening part 22, transversely in the direction of the guide rail 10 and spaced from the recess or receiving groove 8 of the wing 2, which Fig.7 is slidably mounted in laterally arranged cross guides 26, 27 of the guide rail 10. At the other end of the upper horizontal beam 9, the wing 2 is equipped with another roller, which is also attached to the wing 2 in a form-fitting and/or force-fitting manner. The rollers attached to the side of the wing 2 ensure that the upper horizontal area of the movable wing 2 is securely held in place and can be moved.

The drive motor 5 is connected to the threaded spindle 6 via a gear coupling. Other couplings are also conceivable. The carriage 30, which is secured against rotation on the housing 11, can be Fig.4 and Fig.7 however, it is moved along the guide rail 10. For this purpose, the threaded spindle 6 is connected to the rack element 7 in a rotationally effective manner by means of a thread.

To guide the movable sash 2 in the longitudinal direction of the window or door 3 within the frame 4, a slide 30 and a further guide slide 46 are formed on the outer side 45 of the housing 11 facing the rack element 7. The guide slide 46, as well as the slide 30, are arranged above the threaded spindle 6 and engage Fig.7 shaping into a T-shaped guide groove 54 of the rack element 7.

All components of the drive device 1 are inserted into the housing 11 before installation in the window or door 3. Fig. 4 or Fig. 5 For easy assembly and installation of the rack element 7 in the guide rail 10 mounted on the frame 4 and for further coupling of the components in the sash 2, the rack element 7 is Fig.6 formed from tooth segments 50, which can be modularly connected to one another and form an integral structural unit.

When the longitudinal installation position is reached, ie the final assembly state of the rack element 7 in the profile groove 52 of the guide rail 10, the toothed segment 50 is operatively connected to the slide 30 located on the housing 11, the guide slide 46 and the threaded spindle 6 of the drive device 1. The slide 30 and the guide slide 46 are Fig.7 in a T-shaped guide groove 54 of the toothed segments 50. After Fig.4 and Fig.8 on the side of the toothed segments 50 facing the wing 2, there are provided projections of thread flanks 55 which, in effective connection with the threaded spindle 6, provide a rotary Convert movement into a translational movement for moving the wing 2 in the longitudinal direction of the guide rail 10.

In order to equip narrow lift-slide sashes 2 with an automatic drive system or drive device 1 without optical restrictions, the lift-slide sash 2 is fitted with Fig.6 an accumulator 12 is mounted, which is in continuous electrical contact with the drive device 1 during a movement of the movable wing 2 or in the resting position of the wing 2. The movable wing 2 is thereby in a resting position, for example in the closed position to the frame 4 after Fig.5 via a contactor 13 with a contact point 14, which is an extension of the rack element 7, current is supplied to the drive device 1 by bridging the electrical contact of a power source 16 arranged on the frame 4 or in a building wall. For this purpose, the contactor 13 forms a groove 17 for retracting a contact lug 18 arranged on the drive device 1 with a contact point 15 when the lift-slide sash 2 is moved horizontally by the electric drive motor 5. To bridge the contact between the drive motor 5 and the components mounted on the sash 2, the groove 17 is opened in the direction of the sash 2 through an opening 51. In addition, the contact lug 18 remains constantly displaceable while the sash 2 is lowered or to compensate for tolerances in the guide groove 54. Contact between the guide groove 54 and the contact lug 13 remains constant.

After Fig.6 and Fig.9 The accumulator 12 or battery for short is concealed in the receiving groove 8 of the upper, horizontal beam 9 of the lifting-sliding wing 2 near the drive motor 5. Not shown but also possible, the accumulator 12 can be arranged on the vertical beam 23 or 62. This means that Fig.10 a secure power supply is achieved through the power source 16 to the drive motor 5. After Fig.1 The visual appearance of the window or door 3 remains unaffected by the power supply chain, since all components are concealed in the sash 2. The power supply chain can be kept short. Even narrow windows or doors 3 can be equipped with the drive device 1.

The contactor 13 is held vertically in a profile groove 52 of the guide rail 10. The contactor 13 and the rack element 7 are held in the vertical direction by the fact that the profile groove 52 on the side facing the wing 2 is Fig.7 guide surfaces 68, 69 are arranged, resulting in an opening narrowed to the profile groove 52, through which the electric current is transmitted from the power source 16 and further to the movable wing 2 to the drive components. The contactor 13 and the rack element 7 are adapted to the cross section of the profile groove 52 in their external shape so adapted. Both components can be positioned in one position and then fixed in place using fastening means, for simplicity's sake using fastening screws. By fastening and positioning the contactor 13 in the profile groove 52, the rack element 7 that abuts the contact receiver 13 is also secured against displacement in the longitudinal direction of the profile groove 52. For this purpose, the contactor 13 is fastened at both ends of the rack element 7 using fastening screws in the guide groove 10.

To connect the contact point 14 between the contactor 13 and the contact point 15 of the contact lug 18, the groove 17 of the contactor 13 points Fig.8 spring-loaded contact plates 29, which are connected by means of a control and/or power line 44 Fig.1 and Fig.4 Electrical current is transmitted from the power source 16 to the drive device 1.

In addition, the contactor 13 attached to the frame 4 allows the contact lug 18 to be inserted into the groove 17 of the contactor 13 after Fig.4 and Fig.5 to brake and/or stop the lifting/sliding sash 2 in one of the end positions of the closed position, wherein the contact plates 29 are designed as buffers.

As in Fig.4 shown, the contact lug 18 is designed as a web. The contact lug 18 can also be designed as a pin (not shown). The contact lug 18 is designed as a whole or at least with a partial section as a contact point 15. When the lifting-sliding wing 2 is moved in from an open position to Fig.2 and Fig.4 into the closed position Fig.1 and Fig.5 to the frame 4, the contact lug 18 moves into the groove 17 against the contact plates 29 Fig.8 of the contactor 13 and thus establish an electrical connection between the lift-sliding sash 2 and the frame 4.

For the sliding connection of the drive device 1 and for a movable displacement of the sash 2 to the frame 4 in the longitudinal direction of the guide rail 10, a carriage 30 and a guide carriage 46 are formed on the side of the housing 11 of the drive device 1 facing the guide rail 10. With the arrangement of the carriage 30 and the guide carriage 46 above the thread of the threaded spindle 6 and the interaction of the threaded spindle 6 of the motor drive 5 with the tooth segments 50 of the rack element 7, the carriage 30 and the guide carriage 46 are slidably supported in a T-shaped guide groove 54 of the rack element 7.

After Fig.4 the contact lug 18 is adapted to the slide 30 and the guide slide 46 in cross-section I-shaped to the vertical web of the T-shaped design. On The horizontal web is omitted from the contact lug 18 and also from the groove 17 of the contactor 13. The groove 17 is also I-shaped and adapts to the dimensions of the vertical web of the T-shaped guide groove 54. With vertical movement of the sash 2 to the frame 4, the distance within the groove 17 remains with the contact lug 18 retracted after Fig.5 constant. The bridging of the electrical current remains permanently secured.

After Fig.2 and Fig.6 the side 32 of the drive device 1 facing the frame 4 is displaceably connected in the horizontal direction to the components attached to the frame 4. The side 33 of the drive device 1 oriented towards the lift-and-slide sash 2 is mounted and connected to the sash 2 by manually moving the drive device 1 via the resistance of the spindle drive or automatically controlled via the spindle drive from an open end 34, 35 of the upper horizontal beam 9 of the lift-and-slide sash 2 into the recess or receiving groove 8. When the drive device 1 is inserted, the housing 11 of the drive device 1 strikes a limiting part 21 in the receiving groove 8 of the sash 2 with a first front end 19. By attaching a fastening part 22 at the open end 34 of the receiving groove 8 to the second front end 20 of the housing 11, the drive device 1 is fixed in a horizontal longitudinal position. The limiting and fastening parts 21, 22 can be slidably displaced in height with the wing 2 when adjusted in the vertical direction relative to the housing 11.

The end 19 of the housing 11 of the drive device 1 which abuts the limiting part 21 in the receiving groove 8 is a Fig.6 and Fig.10 a contactor 40 in the form of contact plates is attached. A contact point 41 of the contactor 40 establishes a connection to a contact point 42 having a limiting part 21 attached to a movable lifting-sliding wing 2. This completes the power transmission chain for supplying the power source 16 arranged on the frame 4 or in a building wall 43 according to Fig.1 for charging the accumulator 12. Likewise, during the movement of the lifting-sliding wing 2, the accumulator 12 can deliver electrical current to the drive device 1 with the same contact points 41, 42.

After Fig.1 the control and/or power lines 44 form a connecting transmission chain of the electrical current to the individual functional components such as the power source 16, the drive device 1 for pushing and/or drive device for lifting and to the accumulator 12.

The Fig.1 and a partial section of the receiving groove 8 of the horizontal beam 63, that the control and/or power lines 44 are laid completely concealed in the window or door 3, wherein the predominant length section of the control and/or power line 44 extends in a receiving groove of the movable sash 2.

The transmission of the electrical current and/or signals to the respective functional components 16, 1, 12 takes place via the contact points 14, 15, 41, 42. The contact points 14, 15, 41, 42 are in the embodiment shown according to Fig.8 and Fig.10 designed as sliding contacts. Other variants, such as plunger contacts or plug contacts, are also possible.

The limiting part 21 is inserted into the recess or receiving groove 8 Fig. 9 and Fig. 10 connected to the wing 2 by fastening screws (not shown). For this purpose, the limiting part 21 has corresponding holes 47 in the form of countersunk holes for the fastening screws. The fastening part 22 arranged facing the vertical beam 23 of the lifting-sliding wing 2 is supported according to Fig.6 with a first section 36 on the upper horizontal beam 9 in the recess or receiving groove 8. A second section 37 engages in a vertical receptacle of the vertical beam 23 in a form-fitting manner and forms a force-fitting connection with the lifting/sliding sash 2 by means of at least one fastening screw.

When the movable sash 2 is adjusted in the vertical direction relative to the stationary frame 4 in order to raise it into a sliding position or to lower it into a locked closing position of the sash 2, the section 36 of the fastening part 22 slides vertically along the front end 20 of the housing 11 on the side 38 facing the drive motor 5. The horizontally fixed position of the drive motor 6 relative to the limiting and fastening parts 21 and 22 is adjusted with almost no play.
