The cover-side sealing strip, the lifting device and the drive unit, which belong to the cover-side sealing strip, are located in a top of the mobile wall element arranged, horizontal frame member. Correspondingly, the bottom-side sealing strip, the lifting device and the drive unit, which belong to the bottom-side sealing strip, are located in a lower frame element arranged on the wall element. For an emergency operation, a manual actuation of the lifting device is provided at the height of the respective frame element. The disadvantage of this is that the frame element, which is located near the ceiling or the floor, is difficult for the installer to achieve. Another disadvantage is the presence of two drive units, which on the one hand the production costs of Wall element and on the other hand increase the installation costs in the case of manual installation of the wall element.

It is the object of the present invention to provide a movable wall element that can be manufactured and / or assembled inexpensively. Here, in particular, the production of different wall elements are to be standardized. For example, care should be taken that different wall bodies are made possible without having to fundamentally change the mechanism for extending the at least one sealing strip.

To solve this problem, a wall element with the features of claim 1 is proposed. In the dependent claims preferred developments are given.

According to the invention, it is provided that the lifting device and the drive unit are connected to one another via a flexible connecting element, in particular a Bowden cable core of a Bowden cable.

The connecting element bridges a distance between the lifting device and the drive unit. By the connecting element, the drive unit and the lifting device are in mechanical operative connection. In particular, forces can be transmitted from the drive unit to the lifting device via the connecting element. The connecting element is permanently arranged in the wall element.

By providing a flexible connecting element between the lifting device and the drive unit, the drive unit can be placed substantially freely in the wall element. In this way, the wall element can be configured according to different requirements, wherein the structure of a unit consisting of drive unit, connecting element, lifting device and sealing strip substantially unchanged can stay. As a result, the production of the various wall elements can be standardized, so that the development and / or production costs for the wall element decrease. As a result, the wall element according to the invention is inexpensive to produce. Under a flexible connecting element can in particular a flexible connecting element, for. As a wire rope to be understood.

In particular, a Bowden cable of a Bowden cable is provided as a flexible connecting element. The Bowden cable is guided in a Bowden cable case. Here, the Bowden cable both serves as a mechanical guide as well as protection against external environmental influences. Another guide to be arranged in the wall element of the Bowden cable core can advantageously be dispensed with.

The wall element according to the invention may be part of a partition which is composed of a plurality of wall elements. Here, one or more wall elements of the partition may be wall elements according to the invention. The wall element can be moved on rails. For this purpose, the wall element Verfahrelemente, z. B. carriage, have.

The wall element has at least one sealing strip. In the retracted position of the lifting device, the sealing strip is spaced from the ceiling or the floor. During a process of the wall element, the lifting device is in the retracted position. As a result, a grinding of the wall element on the ceiling or the floor can be prevented. If the wall element has reached its destination, then the lifting device is transferred in the extended position. The sealing strip can rest in the extended position of the lifting device on a ceiling or a floor. The sealing strip is now used for thermal insulation and / or sound insulation. In addition, the wall element can be clamped by the sealing strip. Preferably, the wall element has two sealing strips: a first cover-side sealing strip, which is movable via a first lifting device, and a second bottom-side sealing strip, which is movable via a second lifting device. Features disclosed in connection with a fastener are also disclosed as being for the first and second fasteners.

The wall element may have at least one vertical pressure bar. The pressure bar can be moved by a pusher. In a retracted position of the pusher, the pressure bar is remote from a port. In an extended position of the pusher, the pressure bar abuts the port. The connection can be a wall, a stop or another wall element. In particular, a pressure bar is provided only in a last wall element at the end of the partition to bridge a remaining gap. The pressure bar is used for thermal insulation and / or sound insulation. In addition, the wall element and / or the dividing wall can be clamped by the pressure bar. If the lifting devices of all existing sealing strips and optionally the thrust devices of all existing pressure bars are retracted, then the wall element is in a traversing state.

The wall element has a wall body. The large-area wall body corresponds in the assembled state together with the sealing strips in extended lifting devices and optionally a pressure bar in an extended thrust device to be formed by the wall element wall piece. The wall body may be multi-layered, in particular constructed with insulating material and / or cladding material.

The wall body may be formed cuboid at least in the travel state and two visible in the assembled state, large-scale visible surfaces and four narrow side surfaces. In a plan view of one of the visible surfaces of the wall body can be divided into a core region and at least one edge region. The edge region is arranged on a side surface and has an open or closed cavity in order to be able to accommodate at least one functional element at least partially and / or temporarily. The edge area surrounds the cavity. Under a functional element, for example, a drive unit, a lifting device, a sealing strip, a pusher or a pressure bar can be understood. The core region and the edge region can be monolithic. Alternatively, the edge region may have a frame element and / or at least one telescopic element for extending the edge region when the lifting and / or pushing device is extended. The frame element can, for. B. U-shaped or H-shaped. The core region and the edge region can have a common lining on the visible surfaces.

In particular, it is provided that the drive unit is arranged vertically spaced from the edge region in which the lifting device is located. Thus, the drive unit for the first lifting device can be located below an upper, ceiling-side edge region. The drive unit for the second lifting device can be located above a lower, bottom-side edge region. As a result, a manual drive unit is easier and less expensive to operate. In order to increase the operability further, it may be that the drive unit is arranged at a substantially middle height of the wall element. In this case, the drive unit can be moved horizontally to the corresponding lifting device. Due to the flexible connecting element, it is particularly easy to provide a space for the drive unit, which particularly meets the needs of the installer. The connecting element can be correspondingly partially outside the edge region in which the lifting device to be connected to the drive unit is located. In particular, the connecting element can lead to a mean height of the wall element.

Preferably, the connecting element is arranged in at least one edge region of the wall body. In particular, the connecting element is arranged exclusively at least one edge region of the wall body, in particular in at least one frame element. Preferably, the connecting element is arranged in two edge regions. The core region of the wall body remains free of the connecting element. As a result, the core area can be varied, without the need to change the installation of the connecting element. As a result, production and / or development can be further standardized. The core region may, for example, completely or partially transparent, z. B. glass, be formed.

The connecting element may be arranged around an edge of the wall body. The edge is formed in particular perpendicular to the visible surfaces of the wall body. In particular, the connecting element can be guided from a cover-side or bottom-side edge region in a lateral, vertical edge region. Here, the drive unit is arranged in the lateral edge region. This results in easy manual operation of the drive unit. The core area remains free of functional elements. The connecting element can in the process state z. B. be arranged exclusively in two frame elements.

The drive unit can be arranged on the pressure bar. If the pusher is extended, the drive unit, in particular within the edge region, is displaced. In this case, the flexible connecting element, in particular within the edge region, is moved. In this case, the drive unit and / or at least partially the connecting element to be moved from a frame element in a telescopic element of the edge region.

It is conceivable that a first movement of the drive unit, with which the drive unit moves the connecting element, can be converted by the connecting element into a second movement of the connecting element, with which the connecting element acts on the lifting device. In particular, the first movement has a different direction of movement than the second movement. The connecting element thus changes the direction of movement. In particular, the first movement may be a linear substantially vertical movement. The second movement may be a linear substantially horizontal movement.

The drive unit has only one drive element or more, alternatively to be actuated drive elements. The drive element can be operated manually. For example, the drive element can be designed as an angle gear to be actuated via a crank. Alternatively or additionally, an electromotive drive element may be provided. The connecting element may be fastened to a fastening element of the drive unit, which is driven by the drive element. In particular, the drive unit may be a spindle drive. The spindle drive has a drive element, a spindle and a spindle nut. The connecting element may be fastened to the spindle nut as a fastening element.

It is conceivable that the first and the second lifting device are each connected to the same drive unit via a connecting element. The first lifting device is thus connected to the drive unit via a first connecting element and the second lifting device is connected to the drive unit by a second connecting element. In particular, upon actuation of the drive unit, both the first and the second lifting device are moved. The first connection element and the second connecting element can in particular on the same fastening element of the drive unit, for. B. on the same spindle nut, be attached.

In particular, during a movement of the drive unit, in particular of the fastening element, the first and the second lifting device can be retractable in a first direction and the first and the second lifting device can be extended in a second direction during a movement of the drive unit, in particular of the fastening element. In this case, the second direction may be opposite to the first direction. The first and / or second direction may be linear. When moving in the first direction, one connecting element can each be loaded and the other connecting element can be relieved. Accordingly, in a movement of the drive unit in the second direction, the respective other connection element can be loaded or unloaded.

Preferably, the lifting device is movable via a spring. The spring is in mechanical operative connection with the connecting element. In a discharge of the connecting element, the spring can also be partially relieved. If the connecting element is sufficiently relieved, then the movement of the lifting device depends only on the spring. If a release of the spring leads to an extension of the lifting device, then the spring relaxes until the extended position is reached. The spring may be formed, for example, as a tension spring.

It is conceivable that one of the lifting devices is movable via a first spring, which is designed as a tension spring, wherein the other lifting device is movable via a second spring, which is designed as a compression spring. The springs are in operative connection with the respective connecting elements. The springs can be loaded and unloaded together with the associated connecting element. Due to the design of a spring as a tension and the other spring as a compression spring, the lifting devices may have a same extension mechanism, even if the one connecting element loading and the other connecting element are relieved when extending the lifting devices. For example, the lifting devices may be extended when the springs are shortened and retracted when the springs are extended long. If a connecting element is loaded and the other connecting element is relieved during a movement of the drive unit, then, for example, the tension spring can contract while the compression spring is compressed, so that both springs are shortened. Now, if the loading and unloading of the connecting elements reversed, the tension spring is pulled apart, while the compression spring relaxes, so that extend both springs. For example, the lifting devices may be formed like a toggle.

It can be provided that the pusher is movable via the drive unit in the retracted position and in the extended position. This means that the pressure bar via the same drive unit as the at least one sealing strip is movable. As a result, a further drive unit can be omitted.

Thus, the connecting element may be fastened to a first fastening element of the drive unit, while the pushing device is fastened to a second fastening element of the drive unit. In particular, the first and the second fastening element are connected by a spring element. The spring element may be the only connection of the two fastening elements. If both fastening elements are movable, then one of the fastening elements can move the other fastening element via the spring element. If, however, one of the fastening elements is immovable, a relative movement of the fastening elements is possible by the spring element. For example, the first fastening element can be moved by the drive element, which in turn moves the second fastener. The second fastening element can only be moved via the spring element. The first fastener may, for. B. may be a spindle nut of the spindle drive, while the second fastening element may be a thrust bearing.

Preferably, the sealing strip can be moved with a time delay to the pressure bar. For this purpose, the drive unit can be designed accordingly. Thus, in particular, the lifting device can be moved to the extended position after the pusher has reached the extended position. As a result, unfavorable stresses can be prevented within the wall element. Likewise, the at least one lifting device can be moved to the retracted position before the pusher is moved to the retracted position.

In order to move the pressure bar via the drive unit and at the same time to move the pressure bar with a time delay to the lifting device, it is conceivable that during the movement of the pusher, the connecting element with the drive unit is movable without acting on the lifting device.

For this purpose, a Bowden cable casing of the Bowden cable to the second fastening element, on which the pusher is arranged, arranged, in particular fixed, be. If the first and the second fastening element are simultaneously moved by the same amount in the same direction, then the Bowden cable casing and the Bowden cable core are moved together to the same extent. Thus, the Bowdenzugseele does not affect the lifting device.

Preferably, the pusher on a plurality of linkage, which are preferably scissor-like, on. In particular, the linkage extend over a majority of the pressure beam, so that the pressure bar moved evenly. Preferably, the plurality of linkages are moved by the same drive unit. For this purpose, the linkages can be rigidly connected to each other. Further drive units can be omitted in this way. The linkage can be arranged above and below the drive unit.

The invention also provides a mobile partition with at least one wall element according to the invention.

In FIG. 1 a wall body 10 of a wall element 1 according to the invention is shown. Several wall elements 1 form a partition wall. That to the FIGS. 1 to 9 described wall element 1 may in particular be provided at the end of the partition wall element 1.

In an upper part of the FIG. 1 a plan view of the wall body 10 is shown. Here, a large-area visible surface 68 is shown, which faces the users in the assembled state. The visible surface 68 is adjoined by four side surfaces 69. The wall body 10 has a core region 60. On three side surfaces 69, the wall body 10 in each case has an edge region 61, 62, 63, which is configured in each case like a hollow space for receiving functional elements. The edge regions 61, 62 and 63 adjoin the core region 60. In a cavity 67 of the upper edge region 61, a first lifting device 30 for moving a first sealing strip 12 is arranged. Accordingly, the lower edge regions 62, a second lifting device 35 for moving a second sealing strip 13 is arranged. In the lateral edge region 63 are arranged a drive unit 20 and a pusher 41 for moving a pressure bar 40. If the lifting devices 30, 35 and the pusher 41 are retracted, the edge regions 61, 62, 63 can cover the sealing strips 12, 13 and the pressure bar 40. The fourth side surface 69 has no cavity-like edge region.

In a lower part of the FIG. 1 is a sectional view according to the line II shown. It can be seen here that the cavity 67 of the upper edge region 61 has a U-shaped frame element 66. In the frame member 66, a groove is formed, in which the first lifting device 30 may be performed. The core region 60 comprises a material, for example insulating material 65. The insulating material 65 and the frame member 66 are concealed on the visible surfaces 68 of panels 64, which are monolithic and pass from the core portion 60 in the edge portion 61. A corresponding, rotated by 180 ° or 90 ° representation results along the section line II-II and III-III. The section lines II, II-II, III-III are in the upper part of FIG. 1 shown.

A first flexible connecting element 15 leads from the first lifting device 30 in the edge region 61 to the drive unit 20 in the edge region 63. Here, the first connecting element 15 is completely in the first and third edge region 61, 63. Accordingly, a second connecting element 18 leads from that in the second edge region 62 arranged second lifting device 35 to the drive unit 20 in the third edge region 63. Here, the second connection element is completely in the second and third edge region 62, 63 arranged. The core region 60 remains free of connecting elements 15, 18, and can be variably configured according to the requirements of the respective wall element 1.

The first and the second connecting element 15, 18 are formed as Bodenzugseele, which are located in a first and second Bowden cable sheath 16, 19. The connecting element 15, 18 and the associated Bowden cable sheath 16, 19 each form a first and second Bowden cable 14, 17. In that a flexible connecting element 15, 18 is used, this may be performed around an edge 11 of the wall body 10.

In the Figures 2 and 3 is a plan view of an inventive wall element 1 with a wall body 10 according to the FIG. 1 shown. Here, the panels 64 and side walls of the edge regions were not shown, so that the interior of the edge portions 61, 62, 63 is visible. Also not shown are carriages with which the wall element according to the invention can be moved to rails, which are arranged on a ceiling 70 and / or a floor 71.

The drive unit 20 is arranged on the pressure bar 40. The drive unit 20 is connected via the first connecting element 15 to the first lifting device 30, which moves the first sealing strip 12. The same drive unit 20 is connected via a second connecting element 18 with the second lifting device 35, which moves the second sealing strip 13. The same drive unit 20 further moves the pusher 41, over which the pressure bar 40 is moved. The drive unit 20 is arranged at a mean height of the wall element 1.

In the FIG. 2 the first and the second lifting device 30, 35 are shown in a retracted position 50 and the pusher 41 in the retracted position 52. Thus, the first cover-side sealing strip 12 is spaced from a ceiling 70. The second bottom sealing strip 13 is spaced from a bottom 71. The pressure bar 40 is spaced from a wall formed as a terminal 72. In the FIG. 3 In contrast, the first and second lifting devices 30, 35 are in the extended position 51, so that the first and second sealing strips 12, 13 are arranged on the ceiling 70 and the floor 71, respectively. The pusher 41 is shown in the extended position 53 so that the pressure bar 40 is in contact with the wall 72.

The pusher 41 for moving the pressure bar 40 has a first scissors-type linkage 46, which is arranged substantially below the drive unit 20, and a second scissors-type linkage 47, which is arranged substantially above the drive unit 20. The linkages 46, 47 each have two collapsible struts 42. In addition, a support strut 45 for receiving the weight of the wall body 10 is provided in the second linkage 47. The struts 42 are each arranged on the pressure bar 40 and on the wall body 10 via hinge points 43, 44. Here, the struts 42 with movable, in particular guided in grooves, hinge points 43 against fixed hinge points 44 are movable.

The linkages 46, 47 are moved by the same drive unit 20. For this purpose, a pivot point 43 of the first linkage 46 is connected rigidly to a pivot point 43 of the second linkage 47 via a rod 48. The rod 48 is connected to the drive unit 20. If the pressure bar 40 is advanced and the pusher 41 is extended, then the drive unit 20 moves the bar 48 upwardly in accordance with the arrow 73. As a result, the linkages 46, 47 are folded so that the pressure bar 40 is advanced. If, accordingly, the rod 48 is moved downwards against the arrow 73, the linkages 46, 47 unfold and the pressure bar 40 is moved back.

The first and the second lifting device 30, 35 are each connected to the first and the second sealing strip 12, 13 via a pivot point 34. The lifting devices 30, 35 are knee lever-like with two collapsible, articulated levers 39 are formed. The levers 39 of the lifting devices 30, 35 are connected to the wall body 10 each over a hinge connection 32, 33, 37, 38 connected. Here, a hinge connection 33, 38 of each lifting device 30, 35 designed to be movable to the wall body 10 and a hinge connection 32, 37 of each lifting device 30, 35 attached to the wall body 10. The connecting elements 15, 18 engage the movable articulated connections 33, 38. The articulated connections 32, 33 of the first lifting device 30 are connected by a first spring 31, the articulated connections 37, 38 of the second lifting device 35 are connected by a second spring 36. It can also be provided identically designed lifting devices for moving each sealing strip 12, 13 (not shown). The movable joints of the lifting devices for a sealing strip can, for. B. be connected by a rod.

In the FIGS. 4 and 5 the movement mechanism between the drive unit 20 and the lifting devices 30, 35 is shown schematically. The lifting devices 30, 35 are in FIG. 4 in the retracted position 50 and in FIG. 5 shown in the extended position 51. In order to extend the lifting devices 30, 35, a first fastening element 23 of the drive unit 20, to which the connecting elements 15, 18 are fastened, moves upward in accordance with the arrow 73. By this movement, the first connecting element 15 is relieved. As a result, the spring formed as a first spring 31 can contract. The first lifting device 35 is thus transferred to the extended position 51. At the same time, the second connecting element 18 is loaded. As a result, the formed as a compression spring second spring 36 is compressed, causing the second lifting device 35 moves to the extended position 51. The movable articulated joints 33, 38 in this case move in the direction of the arrow 74. If the first fastening element 23 moves counter to the direction of the arrow 73, then the first connecting element 15 and the first spring 31 are loaded. The spring 31 is pulled apart. At the same time, the second connecting element 18 and the second spring 36 is relieved, wherein the second spring 36 is extended. The Extending springs 31, 36 transfer the lifting devices 30, 35 in the retracted position 50th

In the FIGS. 6 to 9 the drive unit 20 is shown in more detail. FIG. 9 is a plan view corresponding to the FIGS. 1 to 5 , The FIGS. 6 to 8 are each a side view of the FIG. 9 , The drive unit 20 is designed as a spindle drive. As in FIG. 9 illustrated, the drive unit 20, a first manual drive element 21, the z. B. is equipped with an angular gear, and a second designed as an electric motor drive element 29. The installer may optionally use the first or the second drive element 21, 29. The drive elements 21, 29 are arranged on opposite sides of a spindle 22. The drive elements 21, 29 may alternatively drive the spindle 22. On the spindle 22 is a spindle nut 23 as a first fastening element. If the spindle 22 is rotated, the spindle nut 23 moves linearly along the spindle 22.

At an extension 26 of the spindle nut 23, the first and the second connecting element 15, 18 are attached. Via the spindle nut 23, the first and the second connecting element 15, 18 are moved linearly during a rotation of the spindle 22.

A second fastening element 24 is arranged in the drive unit 20. The second fastening element 24 is designed as a threadless thrust bearing 24. The thrust bearing 24 is guided along the spindle 22. The spindle nut 23 and the thrust bearing 24 are connected to each other via a spring element 28. On a plate 25 of the fastener 24, both the rod 48 and the first and second Bowden cable sheath 16, 19 are attached.

In FIG. 6 the state of the drive unit 20 is shown, in which the first and the second lifting device 30, 35 in the retracted position 50 and the pusher 41 is in the retracted position 52. If the spindle 22 is now rotated via a drive element 21, 29, then the spindle nut 23 moves linearly upward in accordance with the arrow 73. About the spring element 28 and the thrust bearing 24 is moved to the same extent. As a result, the rod 48 moves upward, so that the pusher 41 extends. The Bowden cable souls 15, 18 are not yet loaded or relieved because at the same time with the Bowden cable cores 15, 18 and the first and second Bowden cable sheath 16, 19 connected to the thrust bearing 24 are moved to the same extent and in the same direction. The first and the second lifting device 30, 35 thus remain in their retracted position 50. The thrust bearing 24 and the pusher 41 reach an end position when the pressure bar 40 abuts the wall 72. This condition is in FIG. 7 shown.

If the spindle 22 now further rotated, the thrust bearing 24 can not be moved further according to arrow 73. However, the spindle nut 23 continues to move. The spring element 28 is now compressed, as in FIG. 8 shown. In this case, now the spindle nut 23 move with the first and second Bowden cable soul 15, 18 in contrast to the first and second Bowden cable sheath 16, 19. Thus, now designed as a Bowden cable soul first connecting element 15 is relieved and the second trained as Bowden cable soul connecting element 18 charged so now the lifting devices 30, 35 of the in FIG. 4 shown state in the in FIG. 5 shown state.

If the spindle 22 is rotated in the opposite direction, then the spindle nut 23 moves linearly in the opposite direction. Starting from FIG. 8 , First, the spring element 28 is relaxed, wherein the lifting devices 30, 35 are transferred to the retracted position 50. Thereafter, the spindle nut 23 moves via the spring element 28, the thrust bearing 24, so that the pusher 41 is moved to the retracted position 52.

As in FIG. 9 shown, the tail 26 of the spindle nut 23 is guided in a slot 27 of the plate 24, so that movement of the spindle nut 23 of FIG. 7 to FIG. 8 is possible.

The wall element according to the invention is also conceivable in modified embodiments. Thus, flexible first and second connecting elements 15, 18 may also be provided in the case of a wall element 1 which has no pressure bar 40. In this embodiment, the pressure bar 40, the pusher 41, the thrust bearing 24 and the spring element 28 are dispensed with. The first and the second cable sheath 16, 19 and the drive elements 21, 29 can be fastened in the lateral edge area 63. The frame element of the lateral edge region 63 can be made closed. Otherwise, the structure of the previously described wall element can be adopted.
