In this way, an arrangement is selected in a simple manner in which a direct transmission of electrical power and / or electrical signals from the frame to the relatively movable sash is possible without cables and at the same time the drive torque is supported on the frame safely and easily on the drive he follows.

According to a preferred embodiment, it is provided that both with a single assembly process - preferably a height adjustment process the mechanical drive component of the drive with the corresponding counter-drive component on the frame as well as the electrical contacts of the drive with the at least one or more busbar arrangement (s) on the frame can be / are coupled. In this way, both the mechanical and the electrical components between the sash drive and the frame are carried out with a common assembly process - for example, an adjustment process of the drive, which makes assembly quick and easy and safe.

In accordance with this embodiment, the invention also provides a method for assembling a wing of a sliding element according to one of the preceding claims, with a drive arranged on it in a height-adjustable manner on a frame, in which the wing is inserted into the frame with the drive preassembled thereon, and in which case with just a single assembly process or - step - preferably a height adjustment process - quickly and easily coupled both the mechanical drive component of the drive and the electrical contacts of the drive with the corresponding counter drive component on the frame and the at least one or more busbar arrangement (s) on the frame will.

According to a particularly advantageous development, it can be provided that the contacts are designed as sliding contacts. It can also be provided that they are designed as pressure spring contacts. This is advantageous but not mandatory. Another configuration of the contacts is also conceivable.

If the contacts are designed as sliding contacts, it is advantageous if they form at least one contact pliers or a plurality of contact pliers, which are then preferably aligned in a row. This is because contact pliers of this type can be arranged in a simple manner in such a way that they can be guided over narrow sides of the busbar arrangements facing them in order to contact them. In this way, with a height adjustment of the drive with the contact pliers, the necessary electrical contact of the drive with the busbar arrangement, which can be sent to a higher-level energy supply device on the frame or a Power network or the like. Can be easily connected to the assembly.

It can further be provided that the drive component on the drive on the wing is designed as an output gear and that the counter drive component on the frame is designed as a rack arrangement. Because in this way, the mechanical coupling of the drive and counter drive components can be implemented in a simple manner with a height adjustment of the drive.

In order to be able to simultaneously couple the electrical contacts - in particular the sliding contacts - and the mechanical drive components at the same time or almost simultaneously during an assembly process, in particular an adjustment process, it is advantageous if the driven gear and the contacts are formed side by side on one side of a housing of the drive .

It can also be advantageously provided that the drive is arranged on the sash frame in a height-adjustable manner in the direction of the frame, wherein a device for height adjustment of the drive relative to the sash frame is provided, with which the output gear and the contacts on the drive are operatively connected to the rack arrangement and the Busbar arrangement can be brought to the frame. In this way, the invention can be implemented simply and well in one variant.

According to a further development, with which a very smooth running of the sash on the frame can be achieved, it is provided that the housing of the drive is supported resiliently on the sash frame of the sash.

According to a constructional further development, which further simplifies the assembly of the sliding element, it can be provided that a blind frame spar having the rack arrangement has a multifunctional rail directed towards the casement frame with a multifunctional contour directed towards the drive gearwheel or that it itself is directly provided with such a multifunctional contour.

According to a further development of these ideas, it can be provided that the multifunctional contour has a fastening contour which is open in the direction of the fold or in the direction of the wing, in particular a preferably undercut receiving groove, for the rack arrangement into which the rack arrangement is inserted.

According to another advantageous development, it can advantageously be provided that the busbar arrangement (s) each have a plastic rail as a carrier, which on one side or on two sides with a conductive material extending in the sliding direction of the wing or x-direction, for example a busbar coating (s) or one or more conductor rail strips is provided, so that two conductor rails are formed on the opposite sides of the plastic rail for applying different potentials. These conductive materials for forming the busbars can also be formed in an extrusion process on a plastic carrier material (coextrusion). A conductive plastic or a metal, for example, are suitable as conductive materials.

It is also advantageous and simplifies control if both drive energy and control signals for the drive can be or are transmitted via the busbars and the contacts.

To implement simple height adjustability, it can further be provided if the drive housing is mounted on a vertically oriented sash frame spar and is arranged on the sash frame spar with the height adjustment device to a limited extent.

According to a further development, which, however, can also be regarded as a further independent invention, it is provided that the window frame, as a mechanical counter-drive component, has one or the rack arrangement, which has at least two or more rack segments arranged in a row, which are held together via a coupling element, that a grid of the toothing of the toothed rack segments is continued via an interface of adjacent toothed rack segments, even if, for example, a grid element in the Transition area may be missing. According to a preferred embodiment, it can further be provided that a comb is used as the coupling element, which has a back and teeth protruding from the back. In this way, a constant grid is also guaranteed across the several rack segments in such a way that the drive can be operated smoothly and smoothly. In this case, provision can be made for the comb to be set on the output gearwheel in a bridge-like manner via the interface of adjacent rack segments on the side of the rack segments facing away from the drive, in order to couple them in a grid.

It is advantageous if, according to a variant, the rack segments are designed as perforated rack segments. It can further be advantageous that a hole pattern or hole grid arranged in the grid serves as toothing, the teeth of the driven gear engaging in the hole grid, the edges of the holes being bent over, so that the web contours between the holes match the tooth contour of the Teeth of the output gear is adjusted. This ensures particularly smooth running of the drive gear on the rack arrangement. According to an advantageous further development, it can further be provided that in the webs between adjacent holes, into which the teeth of the driven gear of the drive engage, recesses are provided on the side facing away from the driven gear, into which the teeth of the coupling element engage, so that engagement of the teeth of the driven gear in the holes is not hindered. This is because on the one hand the grid spacing is also guaranteed across the several perforated rod segments and on the other hand the run is not hindered because the comb does not engage in the perforated pattern but rather a kind of parallel toothing which is formed from the depressions.

It can preferably be provided that the at least one busbar arrangement has an insertion tip and that the contacts each have conical contact heads, so that opposite conical contact heads form a corresponding insertion geometry for the insertion tip.

Figure 1 shows a sliding element 10 with a sliding element frame 100 and a sliding sliding leaf 20 arranged linearly therein with an electric motor drive 300. Such constructions are often also referred to as sliding doors. The term "sliding element" in the context of this document also includes sliding windows and sliding flaps and the like.

The sliding element frame 100 - hereinafter synonymously also called frame - is oriented vertically here. The frame 100 has a first - here upper - horizontal frame spar 101, a second - here lower horizontal frame spar 102, a first - here left - vertical frame spar 103 and a second - frame spar right here 104.

In a coordinate system, the frame 100 extends essentially in an X / Y plane. The horizontal frame spars 101, 102 are aligned parallel to the X direction, the vertical frame spars 103, 104 parallel to the Y direction. The Z direction extends perpendicular to this. The main plane of the is parallel to the X / Y plane.

Also shown schematically simplified is a sliding sash - hereinafter synonymously also called "sash", with a sliding sash frame - hereinafter synonymously also called "sash frame" 200. The sash frame 200 has a first - here upper - horizontal sash frame spar 201, a second - here lower - horizontal sash frame spar 202, a first - here left - vertical sash frame spar 203 and a second - here right wing spar 204. Rolling or lubricants are not shown - typically on the lower sash frame - and the drive 300 for the sash 200, but in Figure 2 and 3rd is shown.

The rollers already mentioned are preferably arranged at the bottom of the wing 20, so that the wing 20 moves back and forth on the frame 100 in a rolling manner can be (not shown here). This is a preferred embodiment but not a mandatory design requirement. In addition, the wing 20 is preferably driven at an upper end and held on the frame 100; however, this is also only a preferred and not a mandatory configuration.

The wing 20 is pivoted here in the direction A obliquely from below upwards into the frame 100 so that its upper wing frame spar 101 can be engaged with a drive 300 inside the upper frame spar 100 with functional elements on this frame spar 101, and then screwed in at its lower end in the direction B in the direction of the lower frame spar 102 such that it can finally be slightly lowered in the frame 100 after reaching a vertical orientation in the direction C, so that its lower rollers or the like on the lower frame spar 102 Plant come.

The wing drive 300 is then adjusted so that it is or is brought into functional engagement with the frame 100 as desired. This is illustrated by the explanations to be explained in addition Fig. 2 and 3rd .

As in 2a-c and 3a-e can be seen, the sash drive - hereinafter also referred to as drive 300 - is arranged and adjustably mounted on the sash frame 200. This is exemplary in Fig. 3a shown in perspective, but the drive 300 can also be configured differently than in FIG Fig. 3a pictured.

The drive 300 has a housing 301 and an output gear 302. In the single or multi-part housing 301 there is an electric motor and transmission elements connected downstream thereof and possibly control electronics Fig. 2 indicated drive gear 301 belongs (not recognizable in detail here). The motor is thus preferably designed as a geared motor, which is advantageous but not mandatory. It is also conceivable - but less preferred - to design the motor and / or the transmission and / or the control electronics separately.

In any case, the drive 300 has the driven gear - here the driven gear 302. The output gear 302 is designed to be brought into engagement with a rack and pinion arrangement 400 on the frame 100 and to roll on it during operation. Since the drive 300 is arranged on the wing 200, this causes the driven gear 302 to roll on the rack arrangement 400, so that the wing moves or shifts linearly in the frame 100 when the driven gear 302 rotates.

The rack arrangement 400 is arranged in one of the frame spars 101, which extend parallel to the direction of movement X. Usually - but not mandatory - this is a horizontal direction.

The rack and pinion arrangement 400 is particularly preferably arranged in the upper, horizontally oriented frame frame 101. Alternatively, however, it can also be arranged in the lower frame spar 102.

It is further advantageous if on the respective other frame frame parallel to the direction of movement X - in Fig. 2 that is, on the lower window frame spar 102 - the roller arrangement or a roller track or a sliding guide (not shown in each case) are designed / arranged so that the sash - possibly provided with rollers - can be moved easily on or in the window frame 100.

The rack arrangement 400 has a plurality of rack segments 401, 402, which are held together by a coupling element 403 in such a way that the toothing or the toothed or perforated grid 405 (without interruption in the correct grid also via interfaces of neighboring rack segments 401, 402 is continued. This is further below in more detail regarding the Figures 4 and 5 described.

The frame spar 101 having the rack arrangement 400 - here upper - can be made in one or more pieces. In a preferred embodiment, he can have a multifunctional rail 110 directed towards the fold or sash frame 100 (see also Fig. 4 ) with a multifunctional contour 111 directed towards the drive gearwheel - or is itself directly provided with such a multifunctional contour 111 (the latter not shown here). To Fig. 1 is the multifunction rail 111 attached to the upper frame spar, here with screws 112 and / or other or other fasteners.

The multifunctional contour 111 has several functional areas. These include a fastening contour open in the direction of the fold or in the direction of the wing 20, in particular a preferably undercut receiving groove 112, for the rack arrangement 400, into which the rack arrangement 400 with its elements is inserted here in the X direction.

This ensures that the toothed or perforated grid 405 of the toothed rack arrangement 400 is exposed vertically downward here, so that the driven gear 302 of the drive 300 can be inserted vertically from below and engages in the assembled state ( Fig. 2c ).

Alternatively, it would be conceivable to form a tooth contour 405 directly in the multifunctional contour, in particular in the multifunctional rail, which is also referred to as a rack arrangement 400 in the sense of this application.

The multifunctional contour 111 then has at least one fastening contour, in particular a fastening groove 113, in which a busbar arrangement 450 is fixed. Particularly preferably, two of these conductor rail arrangements 450 and two of the fastening contours, in particular fastening grooves 113, are provided for fixing one of the conductor rail arrangements 450 in each case.

The fastening contours - in particular fastening grooves 113 - for the busbar arrangements 450 can both be formed side by side on one side - perpendicular to the main plane of the wing 20 - of the fastening contour, in particular receiving groove 112, for the rack arrangement 400. The fastening contours - in particular fastening grooves 113 - for the busbar arrangements 450 can alternatively also be formed on opposite sides - viewed perpendicular to the main plane of the wing - of the fastening contour, in particular receiving groove 112, for the rack arrangement 400. Then the rack arrangement 400 advantageously lies in the middle between the two busbar arrangements 450, which need not be so but is additionally advantageous for perfect operation.

The busbar arrangement (s) 450 can be produced as purely metallic rails. However, it is also preferred that they each have a plastic rail 451 as a carrier, which is provided on one side or on two sides with a busbar coating or a busbar band extending in the x direction. In this way, two busbars 452, 453 can be formed on a busbar arrangement 450 in a simple manner on the opposite sides of the plastic busbar, for applying different potentials, which can be applied, for example, to different poles of a voltage supply device. The plastic rail 451 can have an anchoring foot 454 for anchoring in the fastening groove 113 and / or an insertion aid, here an insertion tip 455 or an insertion wedge. It can additionally be advantageously provided that the contacts 311, 312, which are preferably designed as sliding contacts, each have conical sections or contact heads at the ends of spring arms, so that opposite conical contact heads, which can be spaced apart by a slot, are of a kind form the corresponding insertion geometry for the insertion tip 455.

After that Fig. 2a ) and c) two of the busbar arrangements 450 are provided, a total of four busbars 452, 453 can be provided for four different potentials in a simple manner.

In addition to the drive gear, contact arrangements 310 are formed on the drive 300 from contacts for making electrical contact. These contact arrangements 310 can be designed in various ways. It is provided here that they each have at least one sliding contact 311 or, as shown, each have two opposing sliding contacts 311, 312. The sliding contacts 311, 312 are preferably each formed as one or more compression spring contacts, which in operation act resiliently against the respective assigned busbar 452, 453 press and slide / grind along it in contact.

The design is thus such that the sliding contact (s) 311, 312 slide along the busbars 451, 452 when the sliding leaf 200 is moved. In this way, a corresponding connection of a voltage source to the sliding contacts can be provided, the drives 400 arranged on the wing can be easily connected to a supply voltage and supplied with energy.

The two or more sliding contacts 311, 312 can each form a spring-loaded contact pliers 313, which is designed in such a way that the sliding contacts 311, 312 from opposite sides each press with a spring force laterally against the respective busbars 452 and / or 453 around them to contact. In addition, a plurality of sliding contacts arranged one behind the other can also be provided on each side, which are then virtually in series. This is illustrated by the Fig. 3a and b. The sliding contact arrangements 311, 312 are thus preferably designed like compression springs and preferably like pliers ( Fig. 2a . c ).

A power supply unit on the frame (not shown) is preferably connected to the busbars 452, 453, which in turn can be connected to a higher-level power network. It is also possible and preferred to transmit not only energy but also control signals via the busbars 451, 452. In this way, the drive 300 can be controlled, for example started and stopped and supplied with energy, and the direction of movement can also be reversed, for example. It is also conceivable to vary the speed of the drive 300. Thus, according to a preferred embodiment, controlling signals are also transmitted, for example, which, with a suitable configuration of an actuating electronics, e.g. in a room or directly on the frame and the control electronics of the drive 300 can be easily implemented by electronic means.

In order to couple the output gear 302 and the sliding contacts 311, 312 of the drive 300 with the functional elements rack arrangement 40 arranged on the frame 100 and the one or the two busbar arrangements 450, it is only necessary to drive the drive 300 from below on the wing 20 in this way height Y to adjust its output gear 302 with the rack and pinion arrangement 400 engaged (see Fig. 2b and then 2c) and that during this movement the sliding contacts - here the contact pliers (s) - reach the busbar (s) 452, 453 and make contact with them. For this purpose, the busbar arrangements 450 are aligned here in the X / Y plane or in such a way that they can be exchanged in the slots of the contact pliers 313.

This means that with just a single assembly process - preferably an adjustment process - for example a height adjustment process of the drive 300 - both the mechanical drive component - here the driven gear 302 - of the drive 300 and the electrical contacts of the drive with a corresponding counter drive component on the frame 100 and corresponding ones Busbar arrangements 450 on the frame can be coupled without tools - or if necessary also with a tool such as a screwdriver. This is advantageous since the assembly of the drive 300 on the wing 20 is particularly easy to implement in this way.

In more detail, when inserting the driven gear 302 parallel to or almost simultaneously, the spring-loaded contact pliers 313 with the sliding contacts 311, 312 that meet the busbar arrangements 450 are slightly opened so that they laterally onto the busbars 452, 453 of the busbar arrangement ( en) 450 slide so that they contact them safely springy.

This can be facilitated by the optional insertion aid on the busbar arrangement, which can be formed, for example, by the tapered insertion tip 455 on the plastic rail 451.

In this way, the drive can be supplied or acted upon with electrical energy and / or control signals with simple means and without the need to lay cables between the wing 20 and the frame.

In addition, with just a single coupling movement of the drive 300 - namely with a linear movement of the drive 300 perpendicular to the frame spar 101 - both the torque transmission means - the driven gear 302 on the drive 300 on the wing 20 and the rack and pinion arrangement 400 on the frame 100 as well as the sliding contacts 311, 312 on the drive 300 on the wing 20 and the busbars 352, 353 on the frame 100 are quickly and safely brought into functional engagement or brought into contact position. During assembly, the drive on the wing 20 is mechanically coupled to the frame 100 and the drive is electrically coupled to the frame 100 (see Fig. 2c ).

By appropriate "wide" dimensioning of the busbars 351, 352 in the Y direction or here in the vertical direction, a certain tolerance compensation is also easily possible during assembly, since the sliding contacts 311, 312 do not have the busbars 352, 353 on a specific vertical Need to contact the location but only need to contact at any vertical location. This further simplifies assembly and operation, in particular also when the drive is mounted on the wing 20 in a resilient manner to a limited extent.

The output gear 302 and the contact pliers 313 can - as in Fig. 3 shown - be arranged on a vertically upper narrow side / end face 301a of the drive housing 301 of the drive 300, which is or is attached to one of the vertical casement spars 201-204. However, this is not mandatory. This is because the drive housing 301 could also be attached to the upper, horizontally running casement frame. Then the driven gear 302 and the contact pliers 313 would also have to protrude laterally from the housing 301 (not shown here).

Fig. 3 shows a preferred embodiment of the drive 300. The drive housing 301 is elongated here. It has the upper end face 301a, from which the driven gear 302 and the sliding contacts 311, 312 protrude. At the opposite end or the opposite narrow side / end face 301b, a spring device 314 is provided, which can be designed, for example, as a compression spring socket.

The drive housing 301 is preferably mounted parallel to the horizontal casement strut 302 on the latter. It is preferably provided that the drive housing 301 is limitedly adjustable in height on this casement frame bar 302. A device 320 serves to adjust the height of the drive in the vertical direction. This device can be designed in various ways. A possible embodiment shows the Fig. 3 . The device 320 here initially has a support bracket 321 which can be supported on the sash frame spar 204 or can also be formed integrally therewith. Here, this support bracket is provided with a through hole 322 with an internal thread, through which a screw 323 is screwed, which with its screw shaft 324 presses against the housing 301 from below, in particular via the spring device 314.

By adjusting the screw 322, this is more or less vertically upward from the sheet metal tab 322, so that by adjusting the screw 322 also the vertical height of the drive 300 and thus also the vertical height of the driven gear 302 and the sliding contacts 301 in a simple manner is adjustable ( 3a, b , c, d, e ).

It is preferred that the drive housing 301 engages with at least one or more vertically extending ridges / projections 325 in at least one or more vertically extending grooves 326 on the vertical casement strut 304. This facilitates the height adjustment, since the respective web 325 can slide in the groove in a simple manner. A type of agraff structure can also be formed in this way.

In this way, the drive housing 300 can easily be preassembled on the frame spar 202 in a somewhat vertically lower position. It is then only necessary to make the actual adjustment or height adjustment with the device 320 for height adjustment until the mechanical drive components and the electrical contacts on the drive 300 and on the frame 100 are suitably engaged, in particular in the manner shown in FIG 2a-c is shown. The device 302 for height adjustment is implemented in a structurally simple manner, and simple mounting of the drive 300 on the sash frame and simple height adjustment of the drive 300 is possible.

The rack and pinion arrangement 400 will now be considered in more detail.

As such, it is only necessary to form / provide a rack-like profile on the frame 100, which enables the output gear 302 of the drive 300 to transmit sufficient torque so that the sliding sash 20 on the frame 100 can be moved linearly.

According to a configuration which can be considered on the one hand as a further development of the invention described above and on the other hand also as an independent invention, a particularly simple to assemble and yet very reliable working rack arrangement 400 is created. This is explained below using the exemplary embodiment of FIG Fig. 4 and 5 describe in more detail.

As already stated at the beginning, the rack arrangement 400 has a plurality of rack segments 401, 402, which are held together by a coupling element 403 in such a way that the toothing or the toothed or perforated grid 405 (without interruption in the correct grid also via interfaces of adjacent rack segments 401, 402 is continued.

A type of comb is used as the coupling element 403, which has a back 406 and teeth 407 projecting from the back. The comb is set from the side opposite the driven gear 102 in a bridge-like manner over the interface of adjacent rack segments 401, 402 in order to couple them with grid accuracy.

It is advantageous if perforated racks are used as the rack segments 401, 402, respectively. A perforated pattern or perforated grid 405 arranged in a grid serves here as a toothing, the teeth of the driven gear 302 engaging in the perforated grid. Such a rack can, for example, be produced in a simple manner from a sheet metal strip by means of a stamping / bending process. The edges of the holes 405a, 405b of the rack segments 401 can additionally be bent slightly in one direction, so that the web contours 408 between the holes 305a, 305b are particularly well matched to the tooth contour of the teeth of the driven gear 302. In this way, a smooth and particularly even rolling of the driven gear 302 on the rack segments 401, 402 can be ensured in a simple manner. It becomes a kind of rack gear realized. The perforated bar segments can consist of sheet metal. They can also be coated with a damping material - for example in the manner of flocking or coating - for noise damping.

It is further advantageous if, between adjacent holes 405a, 405b, into which the teeth of the driven gear 302 of the drive 300 engage, recesses 409 are provided in the webs 408 on the side facing away from the driven gear 302, into which the teeth of the coupling element 403 intervention. These troughs 409 are automatically formed in a simple manner, for example in the manufacturing method for the perforated rod segments described in the previous paragraph. An engagement of the teeth of the driven gear 302 in the holes 305a, 305b is not hampered by the coupling element or not significantly.

The distance between the teeth 407 of the comb is then to be adapted to the distance between these troughs 309. In this way, it becomes possible to couple the rack segments 401, 402 in a simple manner with grid accuracy without the drive wheel 302 rolling on the rack arrangement 40 being adversely affected. Rather, it allows excellent rolling on the rack arrangement 450, in which the transitions between the rack segments 401, 402 are not noticeable, even if under certain circumstances. for example, a hole in the grid may be missing in the transition ..

The rack and pinion arrangement 400 can be pushed into the multifunctional rail 110 for the window frame profile on the front side during preassembly during insertion. <b> reference number </b> Sliding element 10th Frame 100 Frame spars 101-104 Multifunction rail 110 Multifunctional contour 11 Groove 112 Mounting grooves 113 wing 20th Casement 200 Casement spar 201-204 drive 300 casing 301 Face 301a Face 301b Output gear 302 Slip contact arrangements 310 Sliding contacts 311, 312 Contact pliers 313 Spring device 314 Height adjustment device 320 Support tab 321 Through hole 322 screw 323 Screw shaft 324 Rack and pinion arrangement 400 Rack segments 401, 402 Coupling element 403 Tooth or hole pattern 405 Holes 405a, 405b move 406 teeth 407 Walkways 408 Hopper 409 Busbar arrangement 450 Plastic rail 451 Busbars 452, 453 top 454 Insertion tip 455 Directions A, B, C Coordinate system X, Y, Z
