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 a sliding window or a sliding door with a frame has become known, in which at least one sliding leaf is movably held, which is movable via a drive and coupled via locking means with the frame, wherein the sliding panel 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 1 914 372 A2 , In this case, designed as a sliding door or sliding door passenger door for vehicles of public transport is provided with at least one sliding in its longitudinal direction door leaf, which is suspended in a support guide and slidably guided. The support guide has for this purpose a linear guide with at least one guide rail on which a guide carriage is guided, and on which the door leaf is suspended via a support arm. The carrying guide is not able to be concealed in a window or door system due to the structural design. Furthermore, the design is expensive in the assembly and with the large number of components expensive to manufacture.

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 In a simple, fast, safe and precise manner, it can also be retrofitted and adjusted, as well as demounted.

This object is achieved by a drive device for a sliding wing as sliding sash or sliding lift-sliding sash 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 at least two carriages, each 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 moved, for example, from a closed position into a fixed 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 spar, 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 driving 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 threaded spindle driven on it. The threaded spindle is forcibly guided around a toothed 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 mounting position of the movable wing in a recess or receiving groove of an upper horizontal spar of the movable wing and a guide frame arranged on the frame. For optimum storage of the drive components of the drive device, the drive motor and the threaded spindle are mounted as a unit forming in a housing. The rack member is almost completely gripped by the guide rail. A gap in the guide rail forms an opening and thus the possibility for coupling between the wing-side components and the frame-side components of the drive device.

As cost-effective and with constructive advantage, the feature proves that the drive motor and the threaded spindle for a rotational transmission of the movement by a positive connection of a flexible shaft or a gimbal are drivingly connected in the longitudinal direction to the direction of displacement of the wing.

The drive motor and the threaded spindle are arranged vertically offset in height and horizontally in the longitudinal direction of the housing and thus to the recess or receiving groove of the movable wing, wherein the drive motor is a bottom plate of the housing and thus a bottom of the recess or receiving groove facing and the threaded spindle of the Floor is spaced in the direction of rack element. With the displacement of the components of the drive motor and the threaded spindle in height within the housing, the drive motor reaches the largest possible space in the housing, wherein the threaded spindle receives the necessary space for unfolding the thread pitch for interaction with the rack member.

A simple assembly and a simple assembly of the housing having drive components is achieved in that, below the drive motor on the side of the bottom plate of the housing, a locking member is provided, which is frictionally clipped into a recess of the housing. For this purpose, elastic locking projections are provided with inlet slopes on the outside of the locking member, the recess adapted to the housing. When mounting the latching projections engage in the recess of the housing with a slight spring force and form a detachable connection with the housing. The drive motor and the threaded spindle with the shaft and a slide can be preassembled as an integral unit by means of the locking member in the housing fixing position. The housing allows the drive motor a secure recording and attachment and the threaded spindle a functionally appropriate storage and protection against dirt and damage. As a result, the integral unit is easily accessible and can also be replaced if necessary. In addition, the locking member is slidably mounted in the recess of the housing. For this purpose, the recess is formed as a slot. With movable storage of the drive components, consisting From the drive motor, the threaded spindle with the shaft and the carriage, via the locking member in the recess, both possible tolerances and an adjustment of the wing to the frame in height, especially in a lifting-sliding sash, can be compensated via the flexible shaft ,

The movable wing comprises four spars, which are formed as hollow sections, in particular as aluminum or plastic profiles or solid profiles consisting of wood. The spars contain prefabricated recesses or grooves for concealed installation of hardware components, especially for the drive device. Thus, the drive device is mounted in a recess or receiving groove in the upper horizontal bar and facing the vertical bar. Preferably, the wing-side components of the drive device in the height H and the width B of the recess or receiving groove of the upper horizontal spar of the wing are adapted. Additional steps for mounting the drive device on the wing thus remain.

In a preferred embodiment, the housing is formed as a U-shaped cross-sectional contour, wherein vary over the length of the housing, the respective side walls, starting from the bottom plate in height. The strip-shaped side walls are due to functional, storage or protective properties vary high. The maximum height of the housing is achieved at the bearing points of the threaded spindle.

For easy attachment, the drive device in the movable wing is releasably fixed in the receiving groove. For this purpose, the respective longitudinal ends of the housing enter into a positive and / or non-positive connection with limiting and fastening parts fastened to the wing. The housing is inserted together with the wing-side components of the drive device as a one-piece component forming an open end of the upper horizontal spar of the movable wing in the recess or receiving groove. One end of the housing causes a horizontally and vertically position-fixed positive connection with a in the recess or receiving groove by means of a non-positively fastened by a fastening screw boundary part. The other end of the housing is held by a further fastening part across in the horizontal and vertical movement positions, said pointing to the vertical spar of the wing attachment part has a circular support with a bore in a arranged on the upper horizontal bar below the recess or receiving groove recording positively engages and received by a fastening screw with the movable wing a positive connection.

For simplified assembly and cost-effective production arranged on the free end of the upper horizontal spar attachment part in the direction of the guide rail transversely and spaced from the recess or receiving groove of the movable wing ball-bearing roller arranged slidably mounted in laterally arranged transverse guides of the guide rail. Likewise, at the other end of the upper horizontal spar preferably another roller is provided, which is positively and / or non-positively attached to the wing. The attached to the wing rollers contribute to a secure sliding support of the upper horizontal portion of the movable sash to the frame. To guide the wing are instead of ball-bearing rollers and height-adjustable sliders or other components used.

For a secure reception of the carriage and the threaded spindle, two spaced stand of the housing extending from the bottom plate in the direction rack element, to a maximum height of the housing to almost the same height of the carriage.

Simple and inexpensive in the design structure proves that the drive motor is connected via a coupling with the driving rotatable shaft, and the shaft is in turn coupled to a rotatably mounted around the stationary carriage around threaded rod of the threaded spindle. On the other hand, the slide secured in the housing can be moved along the guide rail. For this purpose, the threaded spindle is rotationally connected by means of a thread with the rack member. At the respective ends in extension of the central axis, the threaded spindle is formed as a cylindrical rod.

Preferably, the carriage is made of two mold halves, which form a square or a rectangle by positive and / or non-positive connection in cross section. In order to achieve the largest possible space for the thread of the threaded spindle, the carriage has on the respective side surfaces window-like openings into which protrudes the thread of the threaded spindle. The diameter of the thread extends through the openings projecting up to the outside walls of the housing. In addition, the openings can contribute as a safeguard against unintentional displacement of the threaded spindle.

For easy coupling of the threaded spindle, the respective ends of the mold halves of the carriage have semi-circular cutouts, which form by joining a circular cutout for supporting the cylindrical round rod of the threaded spindle for a rotational movement of the thread.

For slidably connecting in the longitudinal direction of the guide rail of the movable wing to the frame and thus the wing-side components of the drive device to the components of the rack member on the frame, a guide carriage is formed on the outside of the slide directed to the rack member. With the arrangement of the guide carriage above the thread of the threaded spindle, the rack member engages between the guide carriage through a groove for cooperation with the threaded spindle.

All component components of the drive device are mounted in the housing and in the guide rail for ease of assembly prior to installation. As a simple handling of the assembly of the rack member in the guide rail convinced the modular juxtaposition of components structurally same tooth segments, which are inserted from both the open side or in the opening of the cross-sectionally U-shaped guide rail in the profile or the channel of the guide rail can. To insert the toothed segments through the slot-like opening extending over the entire length of the guide rail, the toothed segment is formed separately in contour and length.

The toothed segment is preferably made of a plastic injection-molded or a die-cast and is T-shaped in cross-section. The T-shaped shape is created by the shape of the profile of the guide rail. In the inserted state, the toothed segment rests on forming guide surfaces in the interior of the profile groove.

By adhering to a one-piece and inexpensively manufactured article of the toothed segment, the toothed segment is bevelled for mounting through the slot-like opening of the guide rail and modular linking individual tooth segments on the sides over an angle and has a rhombus shaped foot, which is stepped at the respective ends , Due to the angularly tapered sides with tuning the length of the toothed segment, it is possible to mount the toothed segment through the opening in a longitudinally displaceable engaging position of the guide rail with slightly offset rotated position of the toothed segment to the longitudinal direction of the guide rail and thus the slot-like opening.

As soon as further toothed segments have reached the longitudinally displaceable engagement position in the profile groove of the guide rail, the toothed segments can be connected by means of the stepped ends to form a structural unit of a rack element.

For this purpose, the stepped ends of the toothed segments are formed stairs and have the transition of the step or staircase on an undercut, so that there is a positive interlocking linking by screwing the tooth segments. In operative connection of the joined tooth segments, a secured engaging position is achieved in the profile of the guide rail.

Upon reaching the longitudinal installation position, that is, the final assembly state of the rack member in the profile groove of the guide rail, the toothed segments are operatively connected to the carriage located on the movable wing and the threaded spindle of the drive device. For this purpose, the toothed segment on a cover surface in the direction of the wing-side components of the drive device on a guide rail, which is in operative connection with the guide carriage slidably movable operative connection. Further, projections of thread flanks are provided on the top surface, which adapted in the width of the guide carriage of the carriage, in effective connection with the threaded spindle to convert a rotational movement into a translational movement for moving the wing in the longitudinal direction of the guide rail.

The connection of the wing-side components of the drive device via the carriage with the frame arranged on the frame rack member of the drive device via the guide rail, also automatically secures the final assembly position of the drive device for unintentional adjustment of the components and for an operating state for automatically moving the window or door in the horizontal direction , A disassembly of the drive device is possible only after the release of the carriage from the positive connection of the guide rail of the rack member.
