Description

The invention relates to a drive device for a sliding wing as sliding sash or sliding lift-sliding sash of a window or a door according to the preamble of claim 1.

The sliding sashes of systems as sliding sashes or lift-sash panels for a window or door often have a relatively high mass. When moving the wing, especially when pushing from a standing position of the wing must be taken to open a high force. Closing also requires application of resistance to the weight of the wing. Known drives are visibly mounted on the window or the door and are shielded with an additional cover, which greatly affects the look. Likewise, the risk of injury during assembly is increased by disturbing overhead visible components. Furthermore, visible components offer more possibilities for manipulation from the outside. An assembly of such a drive device proves to be complicated from the known prior art.

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

From the EP 2 063 058 B1 is a sliding window or a sliding door with a frame known, in which a sliding wing is movably held, which is movable via a drive and coupled via locking means with the frame, wherein the sliding leaf has four mutually fixed frame profiles. In this case, the drive comprises a driven drive roller, around which a clamping frame fixed to the clamping element is wound, wherein the clamping element is guided over two pulleys and enters a hollow chamber of the frame profile.

The present control device is accessible to the guide rail due to the vertical installation in a vertical spar of the wing only via a deflection to the guide rail, which complicates the construction costly and requires a lot of space in the wing. In addition, the components of the control device of the guide rail are widely spaced apart, which complicates assembly due to individual components components.

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

Also in the above-known door unit, the drive relative to the upper horizontal door lintel extending belt and wheel system is mounted in a vertical door panel of a side member, wherein a functional operative connection only via a deflection to the belt and wheel system of the guide rail is, which complicates the construction costly and requires a lot of space in the wing. The components of the drive and the control device are installed spaced from each other by the belt and wheel system in different door panels, frame units or in the door lintel of the sliding door unit, which makes assembly on the basis of individual component components more difficult.

The object of the present invention is therefore to eliminate the known deficiencies and in contrast provides with low cost and small space a drive for a sliding wing as sliding sash or lift-sliding sash for large carrying capacity and optimal guidance for a window or a door ready, in addition It can also be retrofitted, disassembled and adjusted in a simple, fast, safe and precise manner, as well as following functional and / or tolerance-dependent vertical adjustments.

This object is achieved by a drive device for a sliding wing as Sliding wing or sliding lift-sliding wing of a window or a door with the features of claim 1.

The drive device is to be arranged so that it is suitable for a sliding wing as sliding sash or sliding lift-slide sash for a window or a door. In this case, the movable wing on at least two carriages with rollers to be moved on a running rail in a direction parallel to the extension of the wing or along a running rail. For automatically displaceable operation of the wing, a control element with a switch is preferably provided on a vertical rail, which controls a drive device. With actuation of the operating element, the movable wing can be displaced, for example, from a closed position into a fixed leaf frame and a fixedly mounted wing or door panel. On the other hand, the wing can also bring it into a secure displaced ventilation position or an area of a passage opening. The wing is supported in an advantageous manner on the bottom side having carriages supported on a running rail on the frame movable.

An 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 also be accommodated in a wall of a building and is connected to the operating element and the drive device via control lines.

The operating element can also control a drive arranged in the closing direction on the front of the vertical bar, which also transfers to the vertical bar having locking means in a locked closed position or in an unlocked open position of the wing. 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 sliding sliding sash of a window or door, the movable sash can be conveyed to a raised open position by the drive via the control element automatically or via the manual operating handle from the closed position by a coupled connection of the actuating linkage to the carriages can then 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 for the system are additionally connected to the control lines and linked to the control unit.

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

Advantageously, the drive device for displacing the wing comprises a drive motor arranged on the wing side with a drive roller driven thereon, around which a drive belt fixed to the frame in a guide rail is wound, which is guided via two rotatably mounted deflection rollers of the drive device.

To achieve a constant efficiency with a long service life, the window or the door for automatic alignment of variable height differences of the wing to the frame, for example by forming tolerance adjustments or intentional mechanical adjustment with lifting of the wing by fitting components for laterally moving the wing to the frame, a height adjustment device. In this case, the height adjustment device allows a self-regulating vertical balance between the distance in the height of the arranged on the wing, sliding leaf drive device to the guide rail attached to the frame while maintaining a constant distance of the drive belt to the drive device. At the longitudinal ends of the drive device spring-loaded adapter elements of the height adjustment device are provided, which are connected to the drive device vertically displaceable and attached to the wing.

In order not to interfere with the existing appearance of the window or the door, the drive device in installation position of the wing is almost completely concealed in a recess or receiving groove of an upper, horizontal spar at a fixed door panel directed to the end of the wing and arranged on the frame guide rail , All component components of the drive device are mounted in a housing and in the guide rail for ease of assembly prior to installation. In this case, the drive motor and the drive roller in the housing in stock form a structural unit, wherein the drive belt can be fixed at its respective free ends by means of fastening elements in the guide rail.

Furthermore, an optimally effective drive device requires a backlash-free drive belt in order to prevent possible power losses. Therefore, the drive belt retains a required width at an inherent elasticity. To achieve a high durability and efficiency of the drive belt, at least one fastener to maintain the necessary belt tension of the drive belt on an adjustment. For the sake of simplicity, the adjustment consists of a fixing element rotatably mounted on the adjusting screw, which can tension the drive belt in non-slidably mounted position of the fasteners in a profile of the guide rail fine adjustment for maximum efficiency.

The distance between the drive belt to the drive device is formed as a function of the deflection rollers mounted in the housing and projecting beyond the longitudinally extending, freely visible surface of the housing from respective cutouts. The drive belt is thereby aligned continuously parallel to the drive device via the standing in permanent contact pulleys and remains at a constant distance below a limit of 5 mm from the drive device. Preferably, the drive belt retains due to the self-regulating compensating height adjustment device a continuous parallel distance to the wing-side drive device. Angular courses of the drive belt within the transition region from the drive device to the fastening elements fastened in the frame in the guide rail, which could trigger different stresses in the drive belt, are therefore avoided.

Upon reaching the longitudinal installation position, d. h., The final assembly state of the drive belt in the profile of the guide rail and in the housing of the drive device having components in the receiving groove of the wing, the drive belt covers the housing of the drive device to the frame facing side in operative installation position of the wing almost completely. Furthermore, the drive roller is rotatably mounted positioned at a longitudinal end of the housing, wherein the drive motor of the drive roller of the drive roller operatively connected in the housing adhering lockingly operatively follows. The drive roller directs the drive belt almost vertically with a short distance from the housing on the pulleys. Unnecessary paths of the drive belt with open-visible cutouts of the housing with a large structure in the length of the housing, are thus avoided.

Preferably, the height adjustment device is formed from the adapter elements, which are arranged at the respective longitudinal ends of the housing and form a T-shaped groove in the direction of the housing. For simplicity, the ends of the housing are complementary to the groove of the adapter elements T-shaped and allow each other in the assembled state a vertically displaceable displacement. A detectable displacement is apparent by a parallel removal of the housing of the drive device from the bottom of the receiving groove of the wing with retention of a secured secured position of the adapter elements. The force-loaded housing is raised vertically from the bottom of the receiving groove and adapts itself to the height adjustment of the wing to the frame automatically.

For ease of design, the height adjustment device has a spring element for clamping the housing relative to the adapter element. The trained as a compression spring spring element and the simple structure of the height adjustment device allow easy production, which has an advantageous cost-reducing effect on the drive device.

In order to allow the stored energy of the spring element under constant compression and the components of the height adjustment device a stable mode of action, the adapter element has a receiving bore for complete positional positioning of the spring element, wherein a plate arranged on the housing is inserted into the receiving bore and slidably guided therein with the free end of the spring element is motion coupled.

For secure connection of the housing of the drive device with the adapter element and the height adjustment device while limiting the distance for height adjustment between the housing and the adapter element, a mounting plate by means of fastening screws frictionally connects the adapter element and forms by an interlocking connection with the housing an integral component. A continuous sustained tension of the drive device of the arranged on the wing movable components in the direction of the frame in the guide rail arranged drive belt, which ensures a constant distance between the drive belt and the housing, is achieved in that the mounting plate, the displacement between the adapter element and the Enclosed housing in an end position, wherein the spring element in the end position is still stretched.

A simple assembly before installation of the wing in the frame or in the already installed state and having a simple and inexpensive means fastening device is in Advantageously effective in that the housing with the attached to the respective longitudinal ends adapter elements from one end of the upper horizontal spar of the wing are inserted into the receiving groove, wherein the arranged at the respective ends of the housing adapter elements a horizontal and vertical position-fixed positive connection with a enter into the receiving groove by a fastening screw non-positive connection, each with a boundary part.

In addition, it has proven to be advantageous to the function, installation and cost of the fitting that the drive device with the height adjustment device is independent of the fitting of the actuating linkage on the window or door mountable. Subsequent mounting of the drive device with the height adjustment device is possible without problems even in the already installed state of the window or the door due to the design. In principle, a comfort configuration can be realized simply and inexpensively by the described features for the wing or the lifting-sliding sash of the window or a door.
