Description

TECHNICAL AREA

The present invention relates to the field of sliding Walls. It relates to a sliding stack wall with a plurality of individually movable ones Wall elements, each of the wall elements on its ceiling side Top edge is limited by a horizontally running support profile and by means of at least one undercarriage attached to the support profile in an above of the support profile arranged, common rail can be moved sideways , and wherein each of the wall elements has its own drive with a has electrically operated drive motor, which drive on the wall element is attached and engages with the running rail via drive means.

Such a sliding stacking wall is e.g. from the publication DE-C3-24 04 875 or WO 97/42388.

STATE OF THE ART

In large rooms with variable use such as shopping arcades or the like are increasing for flexible partial or complete separation Sliding stacking walls are used, the individual wall elements of which can be easily moved are suspended from the ceiling, and along a running track to one united wall or on the wall side of the room in one Park position pushed together to a small space-occupying stack can be. Moving the individual wall elements can be done manually respectively; however, automatic solutions are also conceivable in which the individual wall elements driven by an integrated electric motor and controlled by a central controller.

The wall elements themselves can be designed as glass elements, at those without side frame parts to form a continuous glass wall and hanging it up in the running rail on the top a support profile are limited and possibly on the bottom to guide and / or Locking purposes can have a floor profile. The wall elements can also be opaque and made of wood, metal or other wall materials be constructed.

On sliding stack walls of the type described are both in terms of aesthetic appearance as well as practical considerations such as space-saving installation or flexible (modular) expansion or simple Switching from manual to automatic operation increasingly demanding requirements posed, which are only imperfect or even from known solutions not be met. So is from the publication DE-C3-24 04 875 a room partition made of displaceable wall elements known, each can be moved by means of two carriages in a running track fastened under the ceiling are hung. Every single wall element is covered by a Wall element integrated electric motor driven, one on one carriage attached pinion drives, which in the track in another Side wall attached chain, rack or the like engages. The one for the electric motor The electricity required is drawn on the other carriage by pantographs from a busbar running inside the track is removed. Of the The electric motor is standing vertically below the upper crossbar in the double wall Placed area of the wall element. The known solution is therefore not suitable for wall elements that are designed as transparent glass elements are. The same also applies to the room partition wall element disclosed in DE-C2-26 43 905 with motor drive, as well as that described in DE-C2-31 47 273 Room partition.

Furthermore, DE-C2-29 10 185 is a door or the like with a motor Slidable sheet known in which the sheet on a in a support profile is attached by means of tracked wagons. The one intended for the drive Electric motor with a gear in a rack profile in the carrier profile combs, is housed above the carriage in the interior of the support profile. As a result, the type and shape of the sheet can be chosen freely, however, the drive must be accommodated in the running rail support profile a very wide and large volume track that takes up a lot of space and only can be easily integrated into a ceiling. Housing the drive in The running track also makes it necessary for maintenance and maintenance purposes to provide a removable panel, which makes the constructive Structure of the track is further complicated. Otherwise, the one disclosed Solution for a sliding stacking wall with a multitude of individual elements not practical because the power supply to the electric motor via a spiral cable which is laid in the running rail and can be pulled out in length.

In another known removable partition with several plate-shaped Wall elements (EP-B1-0 597 208) are the motorized drive of the wall elements also via a drive unit that works together with the carriage is housed in the ceiling track. Again, one has to be particularly wide and highly trained ceiling rail or top track can be used that much Take up space and make maintenance and assembly difficult.

Finally, in the publication WO 97/42388 mentioned at the beginning there is a sliding wall described, in which the individual wall elements by a horizontal lying electric motor driven, which is attached to the carriage and together with the associated pantographs on the side, i.e. transverse to the running direction protrudes from the carriage. This known solution stands out due to an even greater width in the track area. It also has The solution has the following disadvantage: It is not uncommon for the user a sliding wall first a manually movable wall without a motor Drive installed, but later the built-in wall by adding a wants to automate electric motor drive with control. An afterthought Automation in this case not only requires a lot of effort, but also leads to longer downtimes of the sliding wall. Will be against a guide rail suitable for automatic operation from the start installed, are unacceptable for the simple, manually operated wall high and unnecessary initial costs and an unnecessary increased Space requirements.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a sliding stacking wall that is flexible can be adapted to the most diverse areas of application and use, takes up little space with regard to the guide rail attached to the ceiling, equally for manual without changes in the rail structure and automatic operation is designed, and also increased aesthetic Requirements are sufficient.

The task is thereby in a sliding stack wall of the type mentioned solved that the drive motor is arranged within the support profile. The inventive arrangement of the drive motor in the support profile can the running track attached to the ceiling is extremely slim because there is practically no additional space in the rail for the drive must become. The guide rail only needs, as with manual sliding wall elements is the case for the inclusion and guidance of the running gear. The one required for an electric drive Busbar and the drive means housed in the running rail, e.g. A rack, a toothed belt or the like can save space in the running rail be integrated, so that both for the manual and for the automatic operation the same slim track can be used. This will later change from manual to automatic operation extremely simplified, because in the existing track - if they are not already available - at most a busbar and e.g. a toothed belt must be inserted and the rest of the Wall elements only the existing trolleys by appropriate Trolleys with electromotive drive and pantographs are replaced have to. Furthermore, the arrangement of the drive motor in the support profile Advantage that for the wall element itself a clear one without restrictions Glass pane or any other materials that can be attached to the support profile and element structures can be used because of the space required for the Drive is limited to the support profile.

It is particularly favorable in terms of the space requirement if according to a first preferred embodiment of the sliding stacking wall according to the invention the drive motor with its drive axis parallel to the longitudinal axis of the Support profile is arranged. This way, an elongated, powerful engine not visible from the outside in the support profile without the Cross-sectional area of the support profile can be increased significantly or at all got to.

A preferred development of this embodiment is characterized by this from that the drive means a gear driven by the drive motor comprise, which with a longitudinally extending within the support profile, serrated profile is engaged that the serrated profile into the Carrying profile inserted toothed belt is that the gear wheel is vertical Axis is rotatable and engages in the vertically arranged toothed belt, and that the power transmission from the drive motor to the gear via an angular gear he follows. Due to the vertical arrangement of the gear wheel axis and the toothed belt not only can the drive train be kept compact. Especially The vertical toothed belt is favorable when the running rail is in the Ceiling plane describes curves because of the timing belt in this configuration easily and without additional measures due to its bending properties as a toothed belt follow the curves even with a small radius of curvature can.

Another preferred embodiment of the invention is characterized in that that to supply the drive motor with power within the track a busbar extending in the longitudinal direction of the running rail is arranged, and that each wall element has a chassis, which Electricity from the track by means of pantographs attached to the trolley decreases and forwards to the drive motor. By integrating the busbar The track does not just protect the track by itself against pollution and against accidental contact, but the running track can also be made very compact.

A particularly good use of space is achieved if every wall element has two running gears arranged one behind the other in the direction of travel, and if the wall element is driven by the first drive and the Power is drawn from the second drive.

The track can be easily and equally without modification for manual and automatic operation are used if according to a another preferred embodiment, the running rail as to a central plane Mirror-symmetrical profile rail is formed, which in the interior Has running level on which the trolleys can be moved with idlers, if below the running level two opposite and in the longitudinal direction of the rail extending, inwardly open side grooves are formed, and if in one side groove the busbar and in the other side groove the Timing belt is arranged.

The operation of the sliding stacking wall can be designed very flexibly with the simplest structure of the power supply and control system, if according to another preferred embodiment of the sliding stacking wall according to the invention local control is provided in each of the wall elements, which controls the drive motor of the respective wall element when the local Controls via a data bus with a central control information replace if the busbar is used as the data bus, and if means are provided in each wall element, which information about record the movement of the wall element and proceed to further processing forward the local control of the wall element.

Further embodiments result from the dependent claims.

WAYS OF CARRYING OUT THE INVENTION

In Fig. 1 is a preferred embodiment for a sliding stack wall reproduced in cross section according to the invention. The sliding stacking wall 10 comprises a movable wall element 13 e.g. in the form of a sheet of glass or Like .. The wall element 13 is on the ceiling edge by a support profile 12th limited and held in the lower part of this support profile 12. In the upper part of the Support profile 12 is fastened to a first undercarriage 14 by means of a sliding block 18, that inside a (designed as a hollow profile and attached to the ceiling) Running rail 11 protrudes there and merges into a carriage that with laterally attached support rollers 15 on a running level 40 within the Track 11 is movable in the direction of the rail. For lateral guidance of the Undercarriage 14 in the running rail 11 are below the vertical one Support rollers 15 horizontally lying side guide rollers 16 are arranged. At the Undercarriage 14 is a drive module for the motor drive of wall element 13 17 attached, which - as can be seen from Fig. 2 - one within of the support profile 12 includes horizontally lying electric drive motor 27. The drive motor 27 drives with its drive axis 28 via an angular gear 29 a drive wheel 25 rotatable about a vertical axis. The drive wheel 25 is designed as a gear and in the lower part of the running rail 11 below the Running level 40 arranged where it meshes with a toothed belt 24, the side inserted vertically into a side groove 20 of the running rail 11 and is fixed there. The axis of action of the toothed belt 24 and the axes of the side guide rollers 16 are very close to each other. This ensures that even in curved sections of the running rail and when the drive is permanently installed the drive wheel 25 does not come out of engagement with the toothed belt 24.

A mirror image of the side groove 20 is on the other side of the central plane 26 second side groove 19 is present, in which one extends in the rail direction Busbar 21 with two conductors arranged vertically one above the other 22 and 23 is housed. The conductor rail conducts the electricity that is required for operation of the drive motor 27 is necessary. The electricity is from the power rail 21 removed by pantographs 33, 34, which according to FIGS. 3 and 4 on one second chassis 30 are attached. The second undercarriage 30 is in principle like that first chassis 14 constructed and like the first chassis 14 by means of a sliding block 18 'attached in the corresponding groove of the support profile 12. It sticks out same way into the inside of the running rail 11 and there goes into one Carriage over, with laterally attached support rollers 31 on the running level 40 is movable and for lateral guidance of the chassis 30 below the vertically standing support rollers 31 horizontally lying side guide rollers 32 having. The support rollers 31 of the second chassis 30 are mirror images of the Carrier rollers 15 of the first chassis 14 placed. The same applies to the side guide rollers 16 and 32. Accordingly, the guide rail 11 is mirror-symmetrical to the central plane 26.

The different arrangement of the support rollers 15 and 31 and side guide rollers 16 or 32 in the running rail 11 makes it possible to park the wall elements the running rail 11 in the middle plane in two separate sub-rails to separate and to let the rails run apart. The wall elements then run in the parking area with the one undercarriage in the one partial rail and with the other running gear in the other sub-rail and can be placed diagonally or diagonally and in a row in the majority can be combined into a space-saving stack. The chassis 14 with the drive module 17 and the drive wheel 25 remains due to the arrangement of the Rollers 15, 16 in the partial rail that also contains the toothed belt 24. The Undercarriage 30 with the pantographs 33, 34 remains accordingly in that Partial rail in which the busbar 21 is continued.

The arrangement of the busbar 21 and the toothed belt 24 in the opposite Side grooves 19, 20 of the rail profile is not only space-saving and therefore allows a very compact structure of the rail arrangement. she also ensures that the same track 11 in the same way and without limitation for both manually movable and automatically movable Wall elements 13 can be used. In the lowest stage the side grooves 19, 20 of the running rail can be operated manually be left empty. Wall elements are used accordingly, the same undercarriages 14, 30, but no drive module 17 and none Have pantographs 33, 34. Should switch to automatic operation later become, are in the side grooves 19, 20 of the track 11 simple a busbar 21 and a toothed belt 24 inserted and in the wall elements the existing undercarriages by those with electromotive Drive and pantograph replaced. Further changes are not necessary. Of course, the running rail 11 can also be used from the outset be equipped with a busbar and / or toothed belt. The transition from manual to automatic operation then only requires an exchange of the Undercarriages.

As can be seen from FIG. 3, the current collectors 33, 34 have individual contact elements 35 equipped in the pantographs 33, 34 perpendicular to Busbar 21 slidably supported and by means of a spring 36 against the in the conductor rail 21 insulated conductors 22, 23 are pressed and Form sliding contacts. 3 and 4 is that of the pantograph 33, 34 removed current through power lines 38 to on a connection plate 37 attached connection post 39 forwarded and arrives from there, for example, via a detachable one for assembly or maintenance purposes Plug contact 44 to drive motor 27.

For the targeted movement of the individual wall elements 13 in the running rail 11 from an assigned place in the closed wall to a parking position and vice versa, is a (programmable) central controller 42 according to FIG. 5 provided with the appropriate computing and software capacity, which over a Data bus with local controls equipped with microprocessors 43 data exchanges, which are housed in the individual wall elements 13 and the Movement and the actual state (position, travel speed, acceleration, Control brakes, drive torque, etc.) of the respective wall element and monitor. The data transmission between the central controller 42 and the local controls can be used in different ways, e.g. wireless, done. It is particularly simple and practical to use the busbar as a data bus 21 itself to use, which then also comes from a power supply 41 originating current for the drive modules 17 of the wall elements 13 as also the data exchanged between the controls 42 and 43 is transported. The activation of a special wall element then takes place via a Address code that uniquely characterizes the respective wall element.

The local controls 43 are between the pantographs in the trolleys 30 and the drive motors 27 arranged. The drive motor 27 can for example be equipped with a rotary encoder that can be integrated of the angle of rotation allowed to determine the path covered by the wall element. At the same time, current and voltage can be measured on the drive motor 27 and from this conclusions about the burden e.g. by a sudden obstacle are pulled in the travel of the wall element to initiate a Emergency shutdown can be used. It is also conceivable that Approach of one wall element to another by a proximity sensor to detect, and via the local controller 43 an optimized approach process with reduced speed for example in the last few centimeters perform. It is advantageous that the track 11 for this type of distributed control does not have to be modified, but the very simple one Maintain the structure with a continuous busbar and a continuous toothed belt can.
