Description

The invention relates to a device for space division, in particular a transformable device for space division, which can take several states. The invention further relates to a use of such a device. In addition, the invention relates to a modular system for space division, which comprises at least two such devices.

From the US 3,482,585 A there is known a device for closing a privacy-ensuring area, the device comprising a fixed upper frame and a lower frame movable relative to the upper frame, further comprising a foldable tarpaulin covering the upper frame and the lower frame connects to each other, and wherein a mechanism is provided to lower the lower frame.

From the US 6,786,171 B1 For example, there is known a retractable cover for a boat having an upper frame and a lower frame, the upper frame being fixed to posts, and the lower frame being retractable from the upper frame to deploy a tarp covering a boat ,

From the FR 2 725 741 A1 For example, there is known a similarly designed folding garage for vehicles having vertically extending posts around which extends an upper frame, to which is received an apron-like tarpaulin, said tarpaulin defined being lowerable to enclose a vehicle.

Devices for space division conventional type are well known. It may be about sliding walls, folding walls, sliding doors, folding doors and the like. In general, such devices may be referred to as space separation systems. Room separation systems are generally suitable for temporary separation and / or subdivision of rooms. In this case, the separation and / or subdivision may be appropriate, for example, if large rooms are to be subdivided on a case-by-case basis, in order to bring about a sufficient optical and / or acoustic separation of partial areas.

A large number of office workplaces are now available in so-called open-plan offices, ie in relatively large rooms that can accommodate a large number or a large number of workplaces. Open-plan offices can, on the one hand, promote communication in the workplace, since there are fewer visual and / or acoustic communication barriers. In addition, open-plan offices are suitable for companies that value flat hierarchies, which, for example, strive to provide employees with an equivalent job regardless of their status. Finally, there are working concepts and organizational approaches in the office environment that basically provide anonymous and freely replaceable jobs in open-plan offices. According to this approach, it is conceivable, for example, that a given employee may change his job frequently, for example, depending on his morning work start, to choose a workstation from a pool of available workstations.

Open-plan offices have the further advantage that there is a certain flexibility with regard to their subdivision and / or device, so that changes can be made with manageable effort. Further, for example, in manufacturing facilities, such as assembly halls or the like, sought to provide the largest possible and open spaces available that allow high flexibility and variability in terms of the arrangement and the interaction of different conceivable manufacturing facilities.

Frequently, positive qualities are associated with large spaces, such as space, openness, and creative and / or creative freedom. Large open spaces encourage communication and counteract a sense of trepidation that sometimes crops up in heavily dissected buildings that comprise a multitude of smaller spaces interconnected by a multitude of doors and passageways and / or corridors.

However, it has been found that large rooms, in particular open-plan workplaces, are sometimes considered disadvantageous. This applies in particular to a lack of confidentiality, privacy and / or intimacy. For example, in open-plan offices, it is difficult to hold confidential meetings and / or to exchange confidential information. Typically, companies that use open-plan offices therefore have separate meeting rooms that are almost exclusively usable for meetings. Even in production plants, separate rooms are often kept ready for meetings or for highly concentrated work. This can partly be attributed to the noise pollution in large open spaces for production. In fact, production halls and similar large spaces which can be used for manufacturing and / or assembly purposes are often perceived as loud, since there are regularly a large number of machines, production devices and the like in operation which emit corresponding noises. Thus it can be in Production halls are often simply "too loud" for discussions and / or meetings

Further fields of use are conceivable in which it is desired, at least temporarily, to define separate rooms which are shielded from the surroundings at least sufficiently visually and / or acoustically. This can be, for example, the provision of premises for customer discussions at trade fairs, which are usually carried out in large halls. Furthermore, major events are conceivable that can be held even in the open air. Major events (such as sporting events, concerts and similar cultural events, political events and the like) often require the at least temporary creation of sanitary facilities, medical facilities, rest areas and the like. On the one hand, this may concern the provision of medical care, but also the provision of sanitary facilities. Also, the provision of opportunities for undisturbed moving can be of interest here, such as sports events.

In the case of examples sketched out, it is often important to create or subdivide spaces temporarily in order to create at least sufficient separation for specific purposes. This may relate in particular to an at least partial optical and / or acoustic separation and / or shielding from the environment.

Against this background, the invention has for its object to provide a device for partitioning, which allows a temporary subdivision or creation of rooms with little effort and this ensures an at least partially optical and / or acoustic shielding. Preferably, the device requires only a few separate components, preferably no separate components to be attached to the bottom of a space to be divided. Furthermore, it is preferred if the device is easy to operate, preferably by a person with only little effort. Furthermore, it is preferred if the device is then, when it is not needed, in a visually appealing and space-saving state can be transferred. Preferably, the device also allows creating or dividing rooms in a very short time, without the need for complex separate installation and / or installation work. In addition, as far as possible a modular system should be provided which can utilize the advantages of the device for space division. Finally, a preferred use of such a device should be specified.

With regard to the device, the object of the invention is achieved by a transformable partitioning device comprising a support unit defining a base surface, at least one flexible wall element, preferably at least one foldable or foldable wall element received on the support unit, a power transmission unit attached to the support unit is received and in particular at least one strand-shaped power transmission element, preferably at least one strand-shaped tension element comprises, and with a drive unit which is coupled to the power transmission unit, wherein the at least one flexible wall element by means of the power transmission unit between a first position, in particular a retracted position , and a second position, in particular an extended position is transformable, wherein the at least one flexible wall element is folded or folded in the first position and in the second Ste at least in sections defines a space, wherein the at least one wall element connects a support frame of the support unit with a support frame of a support structure, and wherein the support structure is aligned substantially parallel to the support unit and at the transition between the first and the second position performs a coupled movement, the a rotational component and a thrust component.

The object of the invention is completely solved in this way.

According to the invention, namely, the device in a simple manner between the two positions (which can also be referred to as states or configurations) can be transformed or moved, wherein in the second position preferably a spatial extension is present, which is used for subdivision or separation of a room. Thus, the flexible wall element in the first position may comprise a substantially planar extension and in the second position, a substantially spatial extent. In the first position, the at least one flexible wall element can be present in particular in a folded and / or folded state. Nevertheless, there is preferably a substantially planar extension. In the second position, the at least one flexible wall element can be unfolded or unfolded in order to limit a space at least in sections. The at least one flexible wall element can be designed in particular like a web and, for example, consist of a fabric, a woven fabric, a net, film material, tarpaulin material, plate material and / or another sufficiently deformable material. It is understood that even if the flexible wall element comprises a fabric, a woven fabric or the like, an at least partially optical and / or acoustic Separation of the created space in relation to its environment can be achieved.

The support unit may be sufficiently fixed so that no or at least no significant change in position of the support unit takes place during the transition of the wall element between the first and the second position. By way of example, the carrying unit can be accommodated in an elevated position, for example on a wall, a ceiling or a suitable framework. Accordingly, the support unit may have a defined vertical position, which does not change or at least does not change significantly during the transformation of the device.

The device can be perceived as decorative or optically high quality even in the first position (in which the wall element comprises a substantially flat extension). In addition, in the first position, the (folded or folded) wall element can have a somewhat sound-absorbing effect and thus improve the acoustics of a (large) room in which the device is mounted. Furthermore, the device can also serve in the first position as an optical design element, such as so-called ceiling suspension. Ceiling suspensions are often provided to make excessively high spaces visually appealing and / or to bring about a certain improvement in acoustic properties of the room. In general, the device may be referred to as a so-called room-in-room system. It is understood, however, that the device is basically also usable outdoors, in order to separate rooms there.

A device according to the above aspect can be used as needed as a meeting room, presentation room or the like. Furthermore, a use as a temporary dressing room is conceivable. Another area of application may concern the provision of insect-protected rooms. A further field of application may be, for example, in the context of fairs, presentations and similar high-profile events in which an object is initially (in the second position) protected from view surrounded by the device, wherein the device is activated to move from the second position to the first Position to be transferred to make the object visible from the outside (or to "reveal"). In addition, it is conceivable, when using the device, not primarily to focus on the defined (interior) space, which is defined by the wall element. Such an application field may, for example, relate to the provision of a presentation surface ("screen") for presentations, media presentations and the like. Finally, the device can also be used exclusively or almost exclusively for decorative purposes, such as for the (optical) dissection of oversized rooms or as a light installation (coupled with at least one light source, which may be arranged approximately in an interior defined by the device).

In a preferred embodiment, the support unit is suspended, wherein the at least one flexible wall element in the first position has a substantially flat configuration and in the second position has a substantially spatial configuration. The substantially flat configuration may describe a state in which the flexible wall member is folded. The spatial configuration may, for example, relate to a state in which the at least one flexible wall element defines two, three or four lateral sides of a cuboid or cube. Such a cuboid may further include an upper side and a lower side besides the four lateral sides. On the upper side of the cube, the support unit is arranged. The lower side of the cube is usually facing the ground. It is conceivable that the top and / or the underside of the cube or cuboid by the at least one flexible wall element cover (or "span") to define a completely closed space as possible. However, in many applications it is considered sufficient if the flexible wall element covers at least two or more (lateral) sides of the cuboid or cube.

If the support unit is suspended, the extension of the wall element takes place at the transition between the first position and the second position substantially downwards. By way of example, the extension may be made possible solely or at least partially by gravity, provided that a corresponding barrier is released in the power transmission unit and / or the drive unit.

In principle, however, it is also conceivable not just to receive the support unit hanging, but to arrange it on the floor side. Accordingly, the extension of the flexible wall element can be done "upwards". Thus, the space defined by the device could form in bottom-to-top transformation. Such a configuration lends itself, for example, when the device is to be used under the open sky or there is generally no possibility to record the carrying unit hanging. Furthermore, the bottom attachment can also be used for "unveiling" objects. In the case of the base-side arrangement of the carrying unit, it is preferred if the force-transmitting unit is designed to move the wall element upwards in the desired manner and to support or stiffen it.

According to a further embodiment of the device, the support frame defines a base surface, which preferably has the shape of an n-side n-corner, wherein the at least one wall element is designed web-shaped or tubular and comprises a first end and a second end, which opposite to the first end is arranged, wherein the first end is received on the support frame, and wherein the second end is offset in the second position relative to its initial position in the first position relative to the support frame. This may include in particular that the first end and the second end are rotated by a certain angular amount during the transition between the first position and the second position.

In particular, the n-side n-edge may be a triangle, a quadrilateral, a pentagon, a hexagon, etc. It is understood that the larger the number n, the more the shape of the n-corner approaches the shape of a circle. Accordingly, according to an alternative embodiment, the support unit may comprise a support frame defining a base which is circular or approximately circular.

According to a further development of the device, the second end of the at least one wall element is coupled to the support structure, which determines a base surface, in particular in the second position, wherein the base surface defined by the support structure preferably corresponds to the base surface defined by the support unit. By way of example, the base surface and the base surface can each be designed square or generally n-shaped. Preferably, the square or n-corner is an equilateral geometry. Furthermore, it is preferred if the length of a side of the equilateral geometry which forms the base surface and / or the base surface, preferably at least approximately equal to the (vertical) length of the wall element in the extended state in the second position. In other words, in the extended state, the flexible wall element may have a (vertical) length between the first end and the second end which corresponds to the length of a side edge of the base surface or the base surface. It is understood that according to an alternative embodiment, the base surface and the base can be designed substantially circular. Thus, the wall element may be designed approximately tubular.

According to a further embodiment, the base area and the base area assume a first relative position to one another in the first position and a second relative position to one another in the second position. In the transition between the first position and the second position, a relative movement takes place in the form of a relative rotation between the base surface and the base surface. In this case, it is preferable if the base surface and the base surface are aligned substantially parallel to one another at the transition between the first position and the second position. It is understood that in particular due to the flexible design of the wall element does not always have to be guaranteed a perfect parallel alignment between the base and the base surface.

Preferably, the parallel orientation of the base surface and the base surface during the transition between the first position and the second position by the power transmission unit, in particular by a plurality of strand-shaped power transmission elements, preferably a plurality of string-shaped tension elements defined. If the corresponding plurality of transmission elements is driven sufficiently synchronously, the parallel alignment between the base surface and the base surface can be ensured. In the second position, the parallel alignment between the base surface and the base surface can be ensured on the one hand by the wall element itself. This may be the case, for example, if the at least one force transmission element is relieved in the second position. The device may be designed and received in such a way that the support structure with which the second end of the wall element is coupled rests on the ground in the second position. However, it is also conceivable that the support structure floats in the second position at least partially or completely above the ground.

According to a further embodiment of the device, the relative movement between the base surface and the base surface at the transition between the first position and the second position causes a defined folding or flaps of the at least one flexible wall element. Preferably, defined folding edges are formed at least in the first position. By way of example, the wall element can be twisted in a defined manner if the relative movement between the base surface and the base surface is carried out as a defined relative rotation. According to this embodiment, the base surface is indirectly moved or raised / lowered by the rotation. Overall, even if the wall element is designed sufficiently flexible to be transformable, in the first position, a visually appealing, reproducible state can be ensured. This is particularly advantageous when the wall element is designed substantially fabric-like, fabric-like or otherwise highly flexible.

In the first position, the wall element can be approximately folded such that a design results, wherein the folded edges an opening in the (flat folded) wall element define. The opening can be designed somewhat similar to an iris diaphragm. The opening can serve, for example, as a recess for a lamp, generally a lighting element, or another design element. This design has the advantage that such an element can basically be accommodated on the support unit. In the transition between the first position and the second position, the luminous element or shape element can essentially remain in place. The room "folds" around the element. Thus, for example, when the device is used as a room for meetings or the like, an integrated lighting unit may already be provided which does not have to be mounted first. Such a lighting unit can also be used when the device is in the first position, that is in the substantially flat folded position.

According to a further embodiment, the base surface and the base surface each comprise n-sides, wherein the base surface and the base surface are aligned in the second position substantially congruent to each other, and wherein the base surface and the base surface in the first position have an angular offset from one another. Preferably, the offset angle may be about 360 ° / n. Thus, the offset angle can be about 90 °, if the base surface and the base surface are designed as a rectangle, preferably as a square and each comprise four sides. In other words, the base area and the base area in the second, extended position are preferably congruent, wherein the wall element is not substantially twisted or twisted. In other words, the sides of the wall element which bound approximately (lateral) sides of the space may have a substantially flat extension. Although in the first position, the base surface and the base surface may be basically aligned congruent to each other, but be mutually offset with respect to their relative position of the second position, that the wall element is twisted or twisted.

Preferably, the angle of rotation or a circumferential distance traveled during the rotation is selected as a function of the (vertical) height of the wall element in the second position. Preferably, the congruent orientation of the base and base surfaces in the second position is defined by the extended wall member.

In this context, it is further preferred if the support unit defines a substantially square base surface, wherein the support structure defines a substantially square base surface substantially corresponding to the base surface, and wherein the at least one flexible wall element in the second position four sides of a cuboid or cube defined. If the wall element defines all four (lateral) sides of the cuboid or cube, this can be designed as a shell or tube. It is understood that it is also conceivable that the wall element defines two or three sides of a cuboid or cube, or generally less than n sides of a body with n-sided base. Furthermore, it is conceivable that at least one of the four sides of the cuboid or cube defined by the wall element is provided with an opening.

The design of the space defined in the second position as a cuboid or cube-shaped space, which is defined by substantially square bases or base surfaces, may be a particularly simple "folding" or "folding" of the wall element in the transition from the second position to the first position cause. Namely, if the base surface is rotated by 90 ° with respect to the base, diagonals of the (side) side surfaces of the structure, which are defined by the wall element, formed during the transformation and in the first position defined folding edges. Edges of the cuboid or cube-shaped structure, which are arranged substantially vertically in the second position, can be oriented substantially horizontally in the first, retracted position and can be located in particular between the support unit and the support structure and aligned parallel to the base surface or to the base surface , It is understood that the design of the wall element as a flexible wall element can lead to the folding or folding process is not ideal (in geometric terms) in each case. Nevertheless, in this way in the first position, an at least sufficiently defined reproducible state can be effected, which can also serve decorative purposes.

According to a further embodiment, the at least one flexible wall element in the second position defines a sheath comprising n-sides and n-edges extending substantially vertically, the at least one force-transmitting element at the first end having a first edge and at the second end is coupled to a second edge adjacent the first edge. In other words, in the second position, the at least one force transmission element, preferably the at least one tension element, can extend approximately diagonally across a (lateral) side. It is understood that in the above design with n-sides and n-edges a total of n power transmission elements or tension elements can be provided. Further, n-fold edges may be formed when the device is transferred from the second position to the first position.

According to a further embodiment, the at least one force transmission element at the first end is movably coupled to the first edge and at the second end fixed to the second edge adjacent to the first edge. A "movable" coupling can be effected, for example, by virtue of the fact that the force transmission element, in particular the tension element, is coupled to the second edge via an eye, roller or a similar guide element at the second end. Thus, if the power transmission element is designed approximately as a traction cable, a train on the power transmission element on the one hand cause the corner in which the power transmission element is fixedly coupled to the second edge at the second end, is moved in the direction of the corner of the structure in which the Power transmission element is movably coupled at the first end to the first edge. In this way, the wall element retract or the device can be folded or folded, with a relative rotation between the base and the base surface can be done.

According to a further embodiment, the at least one force transmission element is arranged in the first position such that the first end and the second end are adjacent to each other, that the first edge (or corner) at the first end and the second edge (or corner) second end are adjacent to one another, wherein the at least one force transmission element is arranged in the second position such that the edges of the wall element substantially vertically extend vertically between the base surface and the base surface. A relative rotation defined in this way contributes to making the device visually appealing both in the first position and in the second position.

According to a further embodiment of the device, the at least one flexible wall element has at least one stiffening element. Preferably, the at least one stiffening element in the first position defines a desired position of the folded edges. The at least one stiffening element may be provided as a linkage or at least as a wire-shaped stiffening in the wall element or coupled thereto. By way of example, the at least one stiffening element can be guided as a diagonal over a (lateral) side of the structure in the second position, in order to define the folding edge, which should result in the transition to the first position or in the first position.

Alternatively or additionally, it is conceivable to provide at least one stiffening element in order to sufficiently define in the second position the substantially vertically extending edges of the structure, that is to say approximately the outer edges of the cube, which are formed by the wall element. This can provide a clearer, more clearly contoured shape of the device in the second position. And even if the wall element is designed highly flexible. Alternatively or additionally, the at least one stiffening element can also be designed to define at least one access opening in the wall element. An access opening may concern about a portion of a (lateral) side of the wall element. However, it is also conceivable to open an entire (side) page to allow access to the delimited space. This design has the further advantage that multiple devices can be combined together to define larger spaces.

According to a further embodiment of the device, the drive unit comprises at least one drum-like designed drive element, which is adapted to receive a cable-shaped tension element of the power transmission unit at least partially and release defined in the transition from the first position to the second position. The at least one drum-shaped drive element can be designed approximately in the manner of a rim and comprise a bed on which the tension element can be wound up. In the transition from the first position to the second position, the tension element can be unwound from this area. It is fundamentally conceivable to provide a single drum-shaped drive element in order to receive and deliver all traction elements of the power transmission unit in a defined manner. This has the advantage that the winding and unwinding can be done synchronously. For example, the drum-shaped drive element can be rotated or pivoted about an axis which is oriented perpendicular to the base.

However, it is also conceivable to provide a plurality of drum-shaped drive elements, such as one drive element per tension element. The drive unit preferably has a drive, for example a drive motor, which is coupled to the drive element. The engine may in particular be an electric motor. By way of example, the electric motor may be provided with a power supply unit, such as an accumulator or a battery. However, it can also be used a wired electric motor. Alternatively, it is conceivable to design the drive unit for manual operation. This can be done about ropes, cranks or the like.

As an alternative to tension elements, it would also be conceivable to provide elements which can act as "pressure elements", ie forces can also transmit "pushing". Other designs Drive units for the device are conceivable. By way of example, the drive unit may comprise a plurality of drive elements, which are designed approximately as a telescopic rod. In this configuration, too, it is preferred if the drive elements are designed to move toward one another mutually diagonally opposite corners (lateral) sides of the structure in the second position, in order to be able to transfer the device from the second position to the first position. Other drive elements may comprise lever arrangements, for example an arrangement comprising at least one scissor lever.

According to a further aspect, the object of the invention is achieved by a modular system for spatial division comprising at least two devices according to one of the aforementioned aspects, wherein the at least two devices are arranged adjacent to one another and selectively convertible from the first position to the second position, to provide a plurality of system configurations. In other words, each of the devices may be referred to as a module of the modular system. In this way, further variants of spaces can be formed.

According to a further aspect of the disclosure, the object of the invention is achieved by using a device designed according to one of the aforementioned aspects as a space divider for on-demand spatial division. Preferably, the device is also used, in particular in the first position, as a decorative and acoustically effective ceiling element. More preferably, the device is used as a support for at least one lighting unit, which is preferably arranged in the first position below the level of the (retracted) device and in the second position of the (extended) device within the space defined by the device.

It is understood that the features of the invention mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.

The 1 . 2 and 3 illustrate a first embodiment of a device 10 , in particular a device for defining spaces. Generally, the device can 10 Also referred to as a space divider. The device 10 is in 1 shown in a first (retracted) position. The device 10 is in 2 taken in a second (extended) position. In 3 is the device 10 shown in an intermediate position at the transition between the first position and the second position.

The device 10 has a support unit 12 on that a support frame 14 Are defined. Exemplary is the support frame 14 cuboid shaped and composed of profile elements. The device 10 further comprises at least one wall element 16 , The at least one wall element 16 especially as a flexible wall element 16 be designated. The wall element 16 can be designed as web-like, tube-like or sleeve-like. In the first position of the device 10 according to 1 is the wall element 16 in a folded or folded state and is therefore not shown separately for illustrative purposes. In the second position according to 2 it becomes clear that the wall element 16 may be shaped like a shell, shaft-like or tubular and a plurality of sides 18 can form, which is on edges 20 merge. By way of example, the wall element 16 four pages 18 include, the (side) sides of a cube-shaped or parallelepiped-shaped structure correspond. Accordingly, in the wall element 16 four further substantially vertically extending edges 20 be educated.

In 1 is also only schematically a suspension 22 indicated. The suspension 22 allows a recording of the device 10 on a ceiling, on a suitable frame or on a wall. It is understood that the suspension 22 also deviating from the illustration according to 1 can be realized. Preferably, the suspension is 22 designed such that the carrying unit 12 no or only insignificant intrinsic movements relative to the suspension 22 can perform. In other words, it is preferable if the carrying unit 12 frame side or building side is sufficiently firmly absorbable.

The wall element 16 can be configured to the support frame 14 the carrying unit 12 with a support frame 26 a support structure 24 connect to. By way of example, the wall element 16 a first end 17 and the first end 17 remote second end 27 exhibit. The first end 17 can be referred to as the upper end. The second end 27 can be referred to as the lower end. The first end 17 of the wall element 16 can with the support frame 14 be coupled or recorded on this. The second end 27 of the wall element 16 can with the support frame 26 be coupled or recorded on this.

The support frame 26 can be formed by profile elements. In the support frame 26 may be a bottom opening or a floor 28 are located. According to at least some embodiments, it is preferable if the ground 28 is free when the device 10 located in the second position. However, it would also be conceivable, the wall element 16 also over the ground 28 to extend.

The transition from the first position according to 1 in the second position according to 2 is preferably done by a defined relative movement of the support frame 26 opposite the support frame 14 , An intermediate position of this movement is based on the 3 illustrated. In the transition between the first and the second position, it is preferred if the support frame 14 essentially remains in its initial position. To realize the desired relative movement, the device 10 a power transmission unit 30 on, in particular, at least one strand-shaped power transmission element 32 may comprise, according to the basis of the 1 to 3 illustrated embodiment preferably as tension elements 34 can be designed. The tension elements 34 may be designed as tension cables, pull wires or similar. It is conceivable per page 18 a tension element 34 provided. The following is instead of the term tension element 34 the generic term power transmission element 32 used.

2 further shows that the power transmission elements 32 in the second position, approximately diagonally to the sides 18 can be aligned. In particular, the power transmission elements 32 in the second position mutually offset corners 56 the support structure 24 and corners 54 the carrying unit 12 be assigned. In 2 are two (rear) concealed power transmission elements 32 shown in dashed lines. The three-dimensional shape of the wall element 16 is also illustrated by dashed lines.

The at least one power transmission element 32 in particular is stuck with the corresponding corner 56 the support structure 24 , in particular of the support frame 26 , coupled. On the other hand takes place at the corner 54 the carrying unit 12 , in particular of the support frame 14 , Preferably only a guide of the power transmission element 32 , For this purpose, about each of the corners 54 a diversion 36 be assigned. The diversion 36 can in suitably comprise a roll, eyelet or similar machine element.

About the diversion 36 can the power transmission element 32 with a drive unit 40 the device 10 be coupled. The drive unit 40 For example, at least one drive element 42 include. In the 1 to 3 is the driving element 42 by way of example as a tire or drum 44 shown. Hereinafter, the generic term drive element 42 used. The drive element 42 can basically use a drive motor 46 be coupled, cf. especially 4 , Alternatively, it is also conceivable, the drive unit 40 to train for manual drive. Both motor and manual can indirectly or directly on the drive element 42 be acted to force on the power transmission unit 30 or on its force transmission element (s) 32 exercise. A corresponding movement of the drive element 42 is in 3 through one with 48 indicated arrow illustrates. The movement of the drive element 42 In particular, a train on the at least one power transmission element 42 cause. This train is now on the corner 56 transferred, with the force transmission element 32 is coupled. In this way, the device can be transferred from the first to the second state and vice versa.

According to the basis of the 3 illustrated orientation of the device 10 can the drive element 42 about (in plan view) are driven clockwise to the power transmission element 32 wind. Such a winding operation causes a movement of the support structure 24 or the support frame 26 in the counterclockwise direction (viewed in plan view). Conversely, causes a movement of the drive element 42 counterclockwise unwinding of the power transmission element 32 and thus a movement of the support structure 24 clockwise. The drive element 42 can be configured to all power transmission elements 32 Wind up or unwind synchronously. Accordingly, the support structure 24 essentially parallel to the support unit 12 be aligned and at the transition between the first and the second position perform a coupled movement, on the one hand a rotary component (see 3 With 50 designated arrow) and on the other hand, a thrust component (see 3 With 52 designated arrow) may include.

In principle, it is also conceivable that the at least one force transmission element 32 is extended and guided so that a user can act directly on the device 10 to transform. Thus, the user could relieve or move about in over-long traction cable to the device 10 to move between the two positions. Accordingly, the at least one power transmission element 32 also part of the drive unit 40 be, especially if the drive is done manually.

In the transition between the first position according to 1 and the second position according to 2 can the support structure 24 a total of about 90 ° relative to the support unit 12 twist. During this movement, the wall element becomes 16 defined folded. Overall, during the transformation of the device 10 at least partially defined folding edges or fold lines 58 form. Such a folding edge 58 is in 3 indicated. During the transition, the folding edge 58 as a diagonal of the page 20 (see. 2 ), which are opposite to that through the power transmission element 32 formed diagonal is oriented. It is understood that due to the flexible structure of the wall element 16 the fold edge 58 not (geometrically) must be perfectly formed. However, it is preferable if the folding edge 58 is sufficiently well defined to allow in the first position a defined folding state, cf. especially 6 ,

4 illustrates a plan view of a device 10 , which is basically the basis of 1 to 3 illustrated device 10 can correspond. In 4 is an engine in block diagram 46 indicated in a suitable manner to the drive element 42 can act to twist this defined (in 4 not shown in detail), cf. the arrow 48 , The drive element 42 can be designed radartig and for receiving a total of four power transmission elements 32 be educated. The power transmission elements 32 can the drive element 42 be fed substantially tangentially. In the manner already described above, the power transmission elements 32 along deflections 36 be guided, the corresponding corners 54 of the supporting frame 14 assigned.

5 illustrates a broken detail (view laterally oriented) of a support unit 12 a device 10 that basically the device 10 according to 4 can correspond. In 5 is however an engine 46 provided, for example, central to a rotation axis of the drum 44 executed drive element 42 can be designed. The drive element 42 can be designed like a rim and a peripheral surface 60 have, at which the force transmission element 32 is receivable to wind this controlled or handle. The drive element 32 can be exemplary on carrying roles 62 be picked up and guided on the circumference of the drive element 32 distributed on the carrying unit 12 are included. 4 illustrates that, for example, four each by 90 ° staggered carrying roles 62 can be provided. 5 further illustrates that the diversion 36 For example, it can be configured as a deflection roller, which is receivable on a support arm, with the corresponding corner 54 is coupled. It is understood that other configurations of both the drive element 42 as well as the diversion 36 are conceivable.

6 illustrates a perspective view obliquely from below on a wall element 16 , which is in a folded state, about the basis of the 1 illustrated first position of the device 10 can correspond. In the folded state are the support frame 14 and the support frame 26 at least adjacent to each other. Preferably, the support frame 26 so relative to the support frame 14 pivoted that the support frame 14 and the support frame 26 Although on the one hand are aligned substantially congruent. However, the relative rotation required for this purpose, preferably approximately 90 ° here, can be defined folding or folding in of the previously spatially extending wall element (cf. 2 ) cause. In other words, it is preferred if in the first position of the device of the support frame 14 and the support frame 66 are aligned with each other such that corners 54 . 56 approached in the second position ( 2 ) spaced apart edges 20 of the wall element 16 assigned. To describe the folding process is exemplified on the 9 to 11 referred to, which will be discussed below.

In the folded state according to 6 can be about per page 18 of the wall element 16 a folding edge 58 train at least rudimentary. In the folded state can each have two formerly opposite folding edges 58 (See also the 3 . 10 and 11 ) Diagonally opposite corner 54 . 56 connect with each other. In particular due to the flexible properties of the wall element 16 This can be an opening 66 that evolve through the fold lines 58 is defined. Ideally, if about the wall element 16 describes (lateral) sides of a cube and if the fold edges 58 (geometrically) be folded perfectly, would be the opening 66 tiny. However, it is not a disadvantage if the opening 66 is clearly defined. This can be used on the one hand as a decorative design element when the device 10 in the retracted state in the first position. The opening 66 is designed in the manner of an iris diaphragm. Furthermore, the opening 66 be used to about more design elements, such as a lighting unit, through the opening 66 perform and with the carrying unit 12 to couple or on the support unit 12 take. Such an element can therefore both in the first position according to 1 as well as in the second position according to 2 be used.

To further illustrate the folding process in the transition from the second position to the first position is further exemplified in the 7 and 8th referred, in principle, a design of the device 10 illustrate the design according to the 1 to 3 at least similar. 7 shows a side view of the device 10 , 8th shows a corresponding view of the device 10 at the transition from the second position to the first position. Compared to the representation according to 7 has at least the orientation of the carrying unit 12 not changed. However, the support structure became 24 in principle already described above manner with respect to the support unit 12 twisted. This can be done by a train on or on the power transmission element 32 take place, cf. the arrow 72 in 7 ,

In 7 is the power transmission element 32 that on the side facing away from the view, hidden side of the wall element 16 is arranged, shown in dashed lines. A train on the power transmission element 32 on the one hand causes a retraction of the support structure 24 and further, a relative rotation between the support structure 24 and the carrying unit 12 , see. about the position of the corner 56 in the 7 and 8th , In 8th is the support structure 24 by about 45 ° with respect to their origin orientation in 7 twisted. Already during the in 8th shown position, the corresponding folding edge 58 be formed at least sufficiently defined. As already mentioned above, the folding edge can be 58 from a diagonal of the original page 18 of the wall element 16 derive, in the opposite direction to the power transmission element 32 oriented, which can also be oriented in the second position as a diagonal. The originally substantially vertical edges 20 (see. 2 ) of the wall element 16 may have an arbitrary or undefined shape during the transition between the second and the first position, cf. the reference numerals 70 in 8th , Nevertheless, in the folded state, an at least sufficiently defined shape can result, which corresponds approximately to the design according to FIG 6 at least approximated.

Based on 9 to 11 is based on comparisons of plan views and side views of a highly simplified representation of an embodiment of a device 10 illustrates the transformation between the second position and the first position again. 9 illustrates the second, extended position of the device 10 , The first, retracted position is not shown separately. Transitional states in the transition between the second position and the first position are determined on the basis of 10 and 11 shown. In the 9 to 11 With I . II . III designated views each illustrate a top view, which is associated with a corresponding side view. In basically already prescribed way shows 9 in that in the second position the power transmission element 32 as a diagonal of a page 18 of the wall element 16 can run and with corners 54 . 56 the carrying unit 12 or the support structure 24 be coupled. Further shows 9 that the carrying unit 12 and the support structure 24 are oriented substantially in the same direction (rotational).

10 illustrates a state in which the support structure 24 about 30 ° relative to their original orientation according to 9 pivoted and in a corresponding manner in the direction of the support unit 12 procedure is. The original edges 20 that are between the pages 18 of the wall element 16 have emerged in the second position, can first "come in". It may, however, be on each of the pages 18 an at least sufficiently defined folding edge 58 emerge. The transition between the 9 . 10 and 11 can in particular by a corresponding train on at least one power transmission element 32 be effected.

In the 10 With II designated plan view illustrates a conceivable position of the folded edges 58 each of the pages 18 of the wall element 16 , The closer the device 10 is brought to the first position, the smaller is one by the folding edges 58 defined opening 66 , In 11 becomes an orientation of the support structure 24 illustrates that approximately a twist by a total of 60 ° relative to their original position in 9 equivalent. The device 10 has retracted by a corresponding amount (see vertical arrows 52 in the 10 and 11 ). In the plan views II . III of the 10 and 11 twists the support structure 24 counterclockwise relative to the support unit 12 , see. also the arrow 50 in the 10 and 11 ). It should be understood that the terms "clockwise" and "counterclockwise", as used throughout this disclosure, are not intended to be limiting. If the components involved are oriented and designed in the reverse manner, a rotational movement oriented in the opposite direction can accordingly also take place, so that the designs can be readily transferred.

Furthermore, it is conceivable stiffening elements 80 at the side 18 Provide the side 18 in the area of the recess 78 stiffen sufficiently defined.

13 shows that it is also conceivable to have a recess 78 provide substantially completely over one side 18 of the wall element 16 extends. Again, it may be advantageous to appropriate stiffeners 82 provide, preferably the edges 20 stabilize. This is also conceivable if no recess 78 is provided, cf. 14 ,

13 further illustrates in a highly simplified schematic representation that the drive unit 40 for example, a plurality of drive elements 42 may include, for example, a plurality of drums 44 of which about one drum each 44 one page 18 of the wall element 16 assigned. Further illustrated 13 two states of the power transmission element, that of the recess 78 associated with that 32 and 32 ' are designated. Again, it will be appreciated that it may be advantageous to the power transmission element 32 to give sufficient length to the recess 78 release as much as possible, cf. the with 32 ' designated state. Unless the device 10 Starting from the second position to be converted into the first position again, it is first necessary to tighten the power transmission element, see. the condition 32 until this, in turn, at least approximately one diagonal of the corresponding page 18 equivalent.

14 illustrates another exemplary embodiment of a device 10 , The power transmission unit 30 and the drive unit 40 are shown in simplified form only in block form. The wall element 16 according to 14 has stiffeners 84 which are intended to help, during the transition to the first position and in the first position, the folding edges 58 to define sufficiently, cf. especially 6 . 10 and 11 , In particular, the stiffeners 84 as the power transmission element 32 oppositely oriented diagonal of the respective page 18 be designed. It is understood that the stiffeners 80 . 82 . 84 do not need to be highly rigid. Rather, it is conceivable the stiffeners 80 . 82 . 84 similar to stiffening sails for sailboats or tents for tents. It is further understood that all of the embodiments according to the 12 . 13 and 14 can be combined with each other.

The 15 to 20 show by means of schematically simplified representations exemplary embodiments of base areas 90 or base areas 92 passing through the support frame 14 or the support frame 26 To be defined. In the representations according to the 15 to 20 are the base area 90 and the base area 92 each aligned congruent. It is understood that during the transition of the device 10 between the first position and the second position, a corresponding relative rotation can take place. 15 shows surfaces 90 . 92 in the form of a triangle, the three corners 94 as well as three edges 96 includes. Preferably, all of the surfaces are the 15 to 19 designed as equilateral surfaces. Analogous to the design according to 15 shows 16 a square or square, 17 a pentagon, 18 a hexagon and 19 a dodecagon. A comparison of 19 and 20 shows that a polygon of a circular shape (cf. 20 ) can get closer, the more corners 94 and pages 96 are provided.

All of the designs according to the 15 to 20 can as a basic structure for the supporting frame 14 or the support structure 24 the device 10 serve. It is understood that in particular the representation of the wall element 16 in the folded state, cf. approximately 6 , based on that, the footprint 90 or the base area 92 rectangular, preferably square, that is approximately according to 16 designed. However, it is also understood that also deviating designs to forms of wall elements 16 can lead, which are defined foldable or foldable in the transition from the second position to the first position.

Based on 21 . 22 and 23 are explained advanced applications, which may arise when a plurality of devices 10 is combined with each other. In this context is again exemplified 13 directed. So if at least one of the pages 18 the wall element with a recess 78 provided or through a recess 78 is replaced, the possibility may exist, by appropriate combination of a plurality of devices 10 To provide larger spaces and to make these possibly variable. In this context, it can be generally beneficial if the recesses 78 that roughly based on the 12 and 13 are illustrated, can be temporarily introduced. For this purpose, it is conceivable partial surfaces of the wall element 16 removable or removable.
