Description

The invention relates to a device for driving displaceable, in particular rotatable separating elements and a drive for the drive device and a driven by the drive device separating element according to the preamble of claim 1, 10 and 11 respectively.

For separating or designing rooms or for closing room or window openings glass or wooden walls, scenes, doors or shops are often used, hereinafter referred to as separating elements that are permanently mounted or attached to sliding along a track drives and possibly rotatably mounted and / or or stackable or parkable.

From [1], WO 2004/005656, the drive device shown below in FIG. 1 is known, which serves for driving a separating element 3, which can be displaced linearly and / or in curves, optionally rotatable and parkable, and which is guided on at least two guide rails 100, attached to wheels 211 provided drives 2000, 2001, of which the first drive 2000 is provided with an arranged between the wheels electric motor 43. The vertically oriented drive shaft of the electric motor 43, is connected to a gear 44, which is connected by means of flanges 61, 62 with a connecting shaft 63 which drives a gear 91 which engages in a toothed belt 51. The connecting shaft 63 is rotatably mounted at its upper end by means of a first flange 62 in the housing of the drive 2000 and at its lower end by means of a second flange 64 in a connecting piece 33. The solution disclosed in [1] allows a very compact construction of the drive provided with the drive motor and the transmission.

A disadvantage of this solution, however, is that the compact design results in a high interdependence between the individual device elements, caused by the changes and advancements of the drive each a considerable effort.

Another drive for a guided along a rail sliding door with a compact drive, which is provided with a drive motor is described in [2], EP 1 319 789 A1. The drive motor, which is arranged on the side facing away from the door, that is above a toothed belt engaging in a toothed wheel, and the single impeller are received in the hard drive connected to the door. The drive shaft of the drive motor is provided with a pinion, which is in operative engagement with a ring gear, which is connected to a hub portion of the gear, which is rotatably supported via two bearing rings on a load shaft about its vertical axis of rotation. The load shaft is rotatably mounted about a two-spaced, above the gear arranged bearing rings on a drive body of the drive about the load axis of rotation. The load axis of rotation of the load shaft and the axis of rotation of the gear are therefore coaxial with each other, but arranged offset to the drive shaft of the drive motor. With regard to the arrangement of the load shaft and the gear also results in this drive a compact structure, however, due to the fact that the gear and passing through this load shaft by means of the bearing rings are to be decoupled from each other, which in turn result in undesirable Interdependenzen, even when viewed the arrangement of the drive motor stand out, which must be mounted precisely so that an optimum operative connection between the pinion and the gear wheel gear ring is applied. Changes in the dimensions of the drive body or the dimensions of the drive motor should cause a greater adaptation effort here. After the drive motor already as a geared motor which is normally supplied by a specialized manufacturer, additional gear elements incorporated in the device by the geared motor user must be avoided. This particular because additional transmission elements cause a relatively high manufacturing, assembly and maintenance. The latter in particular because pinion and sprocket are not integrated into a transmission and are protected accordingly and the quality standard of the transmission manufacturer is hardly achievable.

The present invention is therefore an object of the invention to provide an improved drive device in particular for linear or in curves displaceable, optionally rotatable and parkable separating elements. Furthermore, a provided with this drive device drive and a separating element is to be specified.

In particular, a low-cost drive with small dimensions is to be created, whose device parts have a reduced interdependence, so that changes and further developments of the drive can be realized simply, quickly and cost-effectively.

Furthermore, moving or moving parts applied to decoupling and coupling elements, in particular provided on the user side bearing elements and gear elements that cause increased manufacturing and maintenance costs to be avoided.

Furthermore, the inventive drive, especially when driving in tight corners further improved driving characteristics and ensure a reliable coupling between the proposed gear and arranged in the rail timing belt.

This object is achieved with a drive device, a drive and a separating element, which have the features specified in claim 1, 10 and 11, respectively. Advantageous embodiments of the invention are specified in further claims.

a)

das mittels zwei Laufrädern auf einer Lauffläche einer Schiene geführt ist,

b)

das eine mittels eines Elektromotors und eines Getriebes angetriebene Antriebswelle aufweist, die mittels eines Zahnrads mit einem mit der Schiene verbundenen gezahnten Element vorzugsweise einem Zahnriemen gekoppelt ist, und

c)

das mittels einer Lastwelle mit dem Trennelement verbindbar ist.

The device, which serves for driving a linearly displaceable and / or in curves, optionally rotatable and parkable separating element, comprises a drive,

a)

which is guided by means of two wheels on a running surface of a rail,

b)

which has a driven by an electric motor and a gear drive shaft which is preferably coupled by means of a gear with a toothed element connected to the rail, a toothed belt, and

c)

which is connectable by means of a load shaft with the separating element.

According to the invention, the drive has a chassis unit with a drive body, in which the load shaft guided on the underside out of the drive body and two planes guided perpendicular to it on a first side out of the drive body, are held parallel to each other for the wheels and at the top of which has a head piece which is releasably connected to a drive unit in which the electric motor and the transmission are arranged such that the parallel or even coaxial to the load shaft extending drive shaft out of the drive unit, is guided upward, so that on the Drive shaft patch gear can engage in the above the tread of the rail held timing belt.

The inventive solution therefore sees a clear spatial separation of the drive functions and a simple interface between the chassis unit and the Drive unit before, apart from the necessary mechanical, preferably a hinged connection between the chassis unit and the drive unit, the device parts are completely decoupled from each other. In this case, the load shaft and the drive shaft or provided for engagement in the timing belt drive wheel or gear are completely decoupled from each other, which is why corresponding decoupling omitted. The gear is directly driven by the electric motor and the downstream transmission, preferably a one-unit gear motor without the interposition of gear elements. It therefore results in a simple structure of the drive, a reduced production cost and a minimum of maintenance. It is particularly advantageous that the drive unit and the chassis unit can be further developed and maintained independently of each other taking into account the common cutting or connection point. It is therefore possible with minimal development effort to replace the gear motor by a model with other dimensions, as far as the internal dimensions of the rail allow. The manufacturer of the drive device can also obtain the entire drive unit with appropriate quality specifications from a motor and gear manufacturer, which is not burdened with issues of drive technology.

Particularly advantageously, the head piece of the chassis unit, in which recesses may be provided for partially receiving the wheels, forms the bottom of the housing of the drive unit. As a result, the overall dimensions of these two interconnected units as well as the assembly and maintenance costs are further reduced.

On the upper side of the drive unit is preferably an optionally the additional support of the drive shaft serving and provided with a bearing element guide unit fixed or preferably releasably mounted, the one or two as close as possible, guided in an upper guide channel of the rail upper guide elements, guide wheels or sliding elements, carries by means of waves whose axes are parallel to the load shaft axis. By the top guide elements or the guide is guided on the top along a line running parallel to the belt or curve, so that always a correct engagement of the gear is ensured in the timing belt. By using two upper guide elements, torques acting on the drive, in particular caused by the drive unit, are compensated for and direction changes in the track are detected, so that the drive is stably guided. However, if two upper guide elements are used, the intermediate vertical axis of the drive shaft follows a line that always has larger distances to the toothed belt in curves. These deviations from the minimum distance that exists in straight rail sections, change the engagement of the gear in the timing belt and are kept as small as possible, for example by the upper guide elements and their axes are arranged as close to each other as possible. However, this has the consequence that act on the upper guide elements greater forces and the drive is no longer performed with the same precision. For certain load and operating conditions, it may therefore be advantageous if lower guide elements or a support element, a support wheel or a sliding element are provided on the chassis unit. For example, two slightly further spaced lower guide elements can be provided on the chassis unit, which stabilize the drive, while only an upper guide element is used, which ensures optimum engagement of the gear in the timing belt. For further decoupling of Suspension unit and the drive unit, these are preferably connected to each other in such an articulated manner that the drive unit with the gear can tilt against the timing belt without corresponding moments are transmitted to the chassis unit or corresponding force effects on the guide elements arise (see Figure 11).

The body of the chassis unit, the housing of the drive unit and the body of the guide unit are preferably by means of flange positively connected with each other and firmly screwed together by means of at least one of the housing of the drive unit completely passing through mounting screw. This allows the three units mentioned to be connected quickly and stably in the simplest way.

The load shaft is preferably a screw whose shaft is passed through a hole in a central portion of the body of the chassis unit and the head is held in a correspondingly enlarged, at least in the head piece of the body of the chassis unit in projecting bore, which is preferably lockable by means of a securing element , The load shaft can therefore be guided from above through the chassis body until the screw head is preferably rotatably supported in the enlarged bore. The load shaft is therefore held immediately after the drive unit, practically in a housing part of the same and aligned by the central portion of the body of the chassis unit down. On both sides of the load shaft, the two shafts for the wheels lying directly below the head piece on one side of the central piece are held in bores of the central piece. The body of the suspension unit can therefore be manufactured in a minimum size, which still allows the described suspension functions optimally to meet and as the basis for the Assembly of the power transmission and the control device to serve.

Preferably, on the underside of the chassis unit, a contacting module is mounted, which scans a two-wire line serving the power supply, which is arranged in a channel of the rail below the running surface for the wheels.

On the opposite side of the wheels of the chassis unit, above the running surface for the wheels, a control module on the chassis unit, preferably on the shafts of the wheels mounted.

The spatial conditions in the rail and offered by the body of the suspension unit mounting options are therefore optimally combined and used. By the bottleneck, which is formed by the provided on both rail walls rail elements, on the upper sides of the treads are provided, a preferably tapered portion of the central piece is passed with the load shaft provided therein. Preferably, a channel is integrated at least in this part of the central piece, which allows power lines protected by the contacting module through the said bottleneck through to the control module or control lines, by means of which, for example, control signals are transmitted to a closing device of the separating element, from the control module through the bottleneck downwards to lead.

Said rail member with the tread preferably has on its underside a suitable for receiving a connecting pin inner connecting channel, the opening or preferably as far as, for example, 30 °, inwardly inclined, that this or provided in the connecting pin screw elements with a through the lower opening inserted in the rail tool are easily accessible. At the same time is achieved by the inclination of the inner connecting channel or the differently inclined inner connecting channels of both rail sides, that the two rail sections are now aligned in several directions against each other and more precisely connected to each other.

The inserted into a rail channel two-wire line preferably comprises a plastic sheet on which electrical lines are provided and which is provided on both sides with elastic collar, which engage with retaining strips, which are provided at the edges of the rail channel. The two-wire line can therefore be pressed into the rail channel, wherein the elastic collar are compressed and then engage under the retaining strips and fix the two-wire line. The assembly is therefore possible quickly and requires no further mounting means such as screws or adhesives.

The contacting module has resiliently held, preferably supported by spring elements contact pins, which are connected to a screwed to the contacting module circuit board. The contacting module can therefore be assembled and mounted in a simple manner.

FIG. 1 shows the drive device known from FIG. 1, which was described in the introduction.

FIG. 2 shows, in a first embodiment, a rail 1 according to the invention with a middle part 1c which connects two side parts 1a, 1b and is anchored in corresponding channels 15 which run on the upper sides of the side parts 1a, 1b.

FIG. 3 shows the three-part rail 1 of FIG. 2 in a three-dimensional view.

Each of the side parts 1a, 1b has at the lower end of a receiving a two-wire line 52 (see Figures 4 and 16) serving, against the drive 2 open conduit 11, on the outer ends of retaining strips 111, 112 are provided which are used to hold the inserted two-wire line 52 serve. The two-wire line 52 comprises a plastic web 522, on which electrical lines 521 are provided and which is provided on both sides with elastic collar 5221, which engage after insertion of the two-wire line 52 on the retaining strips 111, 112.

Above the conductor channel 11, a rail element 120 is provided, on the upper side of which a running surface 12 for the wheels 211 of the drive 2 is provided. The rail member 120 also has on its underside a suitable for receiving a connecting pin 170 inner connecting channel 17 which is inclined inwardly. On the outside of the side parts 1a, 1b, an outer connecting channel 18 suitable for receiving a connecting pin 170 is provided. The connecting pins 170 are thereby introduced into the corresponding connecting channels 17, 18 of two frontally abutting rail parts 1 and locked, for example by means of screws, which are provided on the front side with ring cutting.

About the rail member 120 is a recording of a toothed belt 51 serving, against the drive 2 open drive channel 13 and above a recording of the upper Guide elements 231 serving, downwardly open upper guide channel 14 is provided.

The drive 2 guided in the rail 1 or on a rail part 1a, which is shown in a sectional view in FIG. 4, has a chassis unit 21, a drive unit 22 arranged above the chassis unit 21 and, in this preferred embodiment, a guide unit arranged above the drive unit 22 23, which are connected to each other by means of at least one mounting screw 24.

The chassis unit 21 has a chassis body 210 in which a load shaft 7 guided on the underside out of the drive body 210 and two shafts 212 parallel to one another and guided out of the chassis body 210 in a plane perpendicular to it on a first side are held for the wheels 211 and at its top a head piece 2101 which is detachably connected to the drive unit 22.

In the drive unit 22, an electric motor 43 and a gear 44, preferably a geared motor are arranged such that a parallel to the load shaft 7 extending drive shaft 9 is guided out of the drive unit 22 also upwards, so that the patch on the drive shaft 9 gear 91 in the above the running surface 12 of the rail 1 held toothed belt 51 can engage. To reduce moments, it is preferably provided that the axes x and y of the load shaft 7 and the drive shaft 9 are coaxial or that the suspension unit 21 and the drive unit 22, as shown in Figure 11, further decoupled from each other by these articulated, for example be connected by means of a connecting shaft 241, such that the drive unit 22 is free to move or guided by the at least one upper guide member 231 against the Timing belt 51 can tilt. From the drive unit 22, therefore, only forces and moments are transmitted to the chassis unit 21, which lie in a plane in which the connecting shaft 241 and preferably also the separating element 3 lie. If the chassis unit 21 and the drive unit 22, however, are firmly connected, occurring moments can be absorbed by a provided on the chassis unit 21 support wheel 2150 (Figure 11 shows both possible embodiments).

Due to the advantageous functional and extensive mechanical decoupling by reduction to elementary connecting elements 24, 241, the chassis unit 21 and the drive unit 22 can be configured independently, which is particularly advantageous. In the drive unit 22, therefore, a commercially available gear motor can be used in a simple manner, without further transmission elements for the power transmission to the gear 91 are required, which is preferably supported by a spacer sleeve 911 and coupled by a wedge 912 with the drive shaft 9. Due to the degree of decoupling achieved, the chassis unit 21 with minimal dimensions can be designed completely in accordance with the chassis functions to be realized, the remaining space inside the rail 1 additionally allowing the advantageous assembly of a power take-off contacting module 41 and a control of the electric motor serving control module 42.

The individual chassis unit 21 is shown in FIGS. 7 and 18 in various sectional views. In Figure 7 it is shown that the load shaft 7 is a screw whose shaft 71 is passed through a bore 2142 in a central portion 2102 of the body 210 of the chassis unit 21 and their head 72 in a correspondingly enlarged, at least in the head piece 2101 of the body 210th the chassis unit 21 is held in projecting bore 2141 which is closed by means of a securing element 8. The chassis 210 thus serves as a support for the load shaft 7 and in this respect provides the widened bore 2141, which is bounded at the bottom by an annular flange element which lies concentrically over the narrower bore 2142. On this flange preferably a ring is provided with rollers, which serves to support the screw head 72. As shown in FIG. 18, the chassis body 210 has on both sides of the widened bore 2141 a respective bore for receiving an impeller shaft 212 whose axes lie in a plane which is pierced vertically by the axis x of the load shaft 7. The impeller shafts 212 are preferably retained in the chassis body 210 so that they may serve as a support for the control module 42 on one side of the chassis 210 for supporting the impellers 211 (see the ball bearings in FIG. 14) and on the other side of the chassis 210 ,

In the embodiment shown, the head piece 2101 of the chassis body 210, in which recesses 219 are provided for partially receiving the wheels 211, the bottom of the housing 220 of the drive unit 22, whereby a smaller overall height of the drive 2 can be realized. FIG. 18 also shows threaded bores 2145, 2146 which serve to receive the mounting screw 24 and a screw 416 by means of which the contacting module 41 is mounted on the underside of the chassis unit 21.

The contacting module 41 has pins 411 supported by springs 417, which are connected to a circuit board 413 screwed to the contacting module 41, from which power supply lines 414 are routed to the control module 42 through a channel 2144 provided in the chassis body 210, preferably via a control line 421 Ribbon cable to the electric motor 43 are guided. The power supply lines 414 are therefore protected by the chassis body 210 passed through the bottleneck, which is formed by the mutually projecting rail members 120. The control module 42, such as a printed and populated circuit, is covered with a sheet 422 and thus mechanically protected and electrically shielded.

FIG. 6 shows the drive unit 22 of simple construction, onto which the guide unit 23 shown in FIG. 5 is mounted, which has a body 230 into which at least one shaft 232 for a guide element 231 is inserted, which is located in the rail 1 along the upper guide channel 14 to be led.

The chassis body 210, the housing 220 of the drive unit 22 and the body 230 of the guide unit 23 are by means of flange 216, 236 positively connected with each other and at least one of the housing 220 of the drive unit 22 completely passing through mounting screw 24 firmly screwed together and therefore with a few simple steps and demountable.

Figure 8 shows the additionally provided with a support wheel 2150 drive 2 of Figure 2 with different cutting lines S1, ..., S4. FIG. 9 shows the drive 2 from FIG. 8 from below. FIG. 10 shows the drive 2 from FIG. 8 from above. FIG. 11 shows the modified drive 2 of FIG. 8 from the side, connected to a profile part 31 of a separating element 3. As described above, disturbing moments can be absorbed by the support wheel 2150 provided on the chassis body 210. By means of the articulated connection of the chassis unit 21 and the drive unit 22 shown in FIG. 11, disturbing forces and moments can be completely eliminated. The articulated connection can be made simply by means of a connecting shaft 241, which is inserted into corresponding bores in the chassis body 210 and in the housing 220.

The suspension unit 21 and the drive unit 22 can therefore be separated from each other by removing the connection shaft 241.

FIG. 12 shows the drive 2 of FIG. 8 cut along the section line S1 with the uncovered gear 91 engaged in the toothed belt 51.

FIG. 13 shows the drive 2 of FIG. 8 cut along the section line S2 with the drive motor 43 exposed.

FIG. 14 shows the drive 2 of FIG. 8 cut along the section line S3 with cut-away wheels 211 and their shafts 212 and elements of a ball bearing.

FIG. 15 shows the drive 2 of FIG. 8 cut along the section line S4 with a cut-open contacting unit 41, in which channels 415 are provided for the contact pins 411 supported by springs 417.

FIG. 16 shows a rail part 1a in which the rail element 120 provided with the running surface 12 is provided on its underside on the one hand with the inner connecting channel 17 and additionally with a lower guide channel 16 open at the bottom, in which one or two guide elements connected to the chassis body 210 215 are guided.

FIG. 16a shows two upper guide elements 231 running in a curve K2. FIG. 16b shows an upper guide element 231 running in the curve K2, which together with the gear 71 can precisely follow the course of the toothed belt. By using two upper guide elements 231, torques acting on the drive, in particular caused by the drive unit 22, are compensated for and changes in direction in the track are detected, so that the drive 2 is stably guided. If two upper Guide elements 231 are used, follows the intervening axis y of the drive shaft 9, however, a line that always assumes greater distances to the timing belt 51 in curves. With increasing distance of the shafts 232 of the upper guide elements 231, the distance from the gear 91 to the toothed belt 51 increases. This distance can therefore be reduced if the mutual distance of the shafts 232 is reduced as much as possible. However, this has the consequence that acting on the upper guide elements 231 greater forces and the drive 2 is no longer performed with the same precision. For certain load and operating conditions, it may therefore be advantageous if two lower guide elements 215 are provided on the chassis unit 21, by which the drive 2 is stably guided. As a result, only an upper guide element 231 can be used which ensures optimum engagement of the toothed belt in the toothed belt. FIG. 17 shows a correspondingly configured drive 2 with an upper guide element 231 and two lower guide elements 215. In the same way, therefore, the drive 2 shown in FIG. 11 can be configured, in which an optimal engagement of the toothed wheel 91 in the toothed belt 51 is always guaranteed , In FIG. 17, therefore, both alternatively usable possibilities for connecting the chassis unit 21 and the drive unit 22 are shown, namely the rigid connection by means of the mounting screw 24 and the articulated connection by means of the shaft 241.

The solution according to the invention can also be implemented advantageously if, instead of the running wheels 211 and running surfaces 212, sliding members serving for carrying the separating element 3 are provided, which are mounted on sliding surfaces of the rail.
