Abstract

A variable effect roller blind has at least two panels of different material fitted one above the other. One roller is attached to each panel to wind each panel separately and thereby achieve different covering effects for the blind. Typical panel types include a material which shades while providing ventilation and a rain protection panel. The rollers can be fitted in different positions on the panels.

Description

The present invention relates to a winding device, in particular a winding blind with the features of the independent claim.

Areas of application for such winding blinds are diverse. For example, they are used for variable shielding of rooms, for variable ventilation and / or shading of animal houses, greenhouses or the like. Usually, such shielding devices roll systems with variably aufund roll-up tissue webs in order to enable a desired shading or shielding of the building or wall opening.

Conventional Venetian blind devices, in which a rotatable winding roll is arranged above an opening to be covered, only allow a Aufund unrolling of the fabric web on the winding roll and thus a variable opening towards the top. Such Venetian blinds serve, for example, for the shading of window openings in houses and apartments. In addition, there are blind devices in which an upper longitudinal side of a fabric web rigidly fixed and a lower longitudinal side is provided with a height-adjustable winding roll. Such blinds are used, for example, in greenhouses. The fabric web can be opened in such conventional winding devices only from bottom to top, which is unfavorable for some applications.

Thus, for example, in animal stalls, a constant covering of the lower region of the opening is desired with an upper area which is simultaneously adjustable in terms of air and / or translucency. For this reason, more variable shielding devices have become known in which the winding roll previously arranged rigidly above the opening to be covered is designed to be height-adjustable. Such a shielding device, in which an upper winding roll or an upper fixation of a fabric web is made adjustable in height by means of a cable system is, for example. From the DE 103 36 944 A1 known. However, the upper cable guide here is relatively complex, difficult to adjust and susceptible to interference in prolonged operation.

Another system for variable ventilation and / or shading of buildings or rooms is from the DE 202 14 076 U1 known. This device comprises an upper and a lower roll system for winding and unwinding a screen, so that different types of fabric can optionally be rolled up on the upper or lower winding roll. As a result, the space is, for example, shaded with a denser type of fabric or rendered air and light-permeable by means of a very wide-meshed woven fabric. The two winding elements are each anchored rigidly above and below the space opening. Such a device can not extend over any width, since the differences in the diameters of the upper and lower rollers must be compensated at all times by means of a jig and the storage of the upper winding roll is problematic for very wide and thus heavy Abschirmbahnen. The use of such a device to cover a very wide area thus requires a series of several such devices.

A similar kind of roller blind device with a first and a deviated second material web, which are each wound around a winding axis, and which are each secured with a first end in the region of its winding axis to a holder, is further from the DE 92 10 938 U1 named. The first and the second material web are firmly connected to one another at their free second end and the holders are movable relative to one another toward or away from one another, the two material webs being able to be unwound or unwound during these movements.

A flexible shielding device for very large openings, eg. For the separation of rooms in aircraft hangars, is from the US 3,306,344 A known. This comprises a flexible curtain whose upper edge is attached to a horizontal head portion and whose side edges extend in lateral guide elements, one or more horizontally arranged rollers attached to the curtain, and drive means for simultaneously rotating the rollers at the same speed, opening upon opening the curtain moves each of the rollers upwards because they wrap around portions of the curtain above and below them. Such a shielding device can have almost any width due to the rigid attachment to the upper edge. The winding technique leads to an accelerated according to the number of rollers used winding and thus a fast opening and closing of large areas.

An object of the present invention is a winding device according to the preamble of claim 1 for the variable covering of surfaces, for example. Openings in rooms or buildings, with surface paths of different textures or to cropping these surfaces as known from WO-A-03076756
to provide, which is simple to set up and operate and which is also suitable for large areas.

This object of the invention is achieved with the subject matter of the independent claim. Features of advantageous developments of the invention will become apparent from the dependent claims.

The winding device according to the invention with the features of the independent claim allows variable coverage of surfaces, for example. Openings in rooms or buildings.

With the winding device according to the invention, it is possible to open or close or shadow or largely release an opening to be covered or released in a housing, a building, a stable, a greenhouse or the like variable. Thus, the winding device according to the invention represents an advantageous development, since the currently known blind devices with upper rigid attachment do not allow variable venting an upper opening with simultaneous coverage of a lower portion of the opening.

In addition to those already mentioned, there are numerous other fields of application for the winding device according to the invention. Thus, such winding devices can be used as mobile partitions in outdoor and / or indoor use, for example. As mobile partitions in production halls that can meet a variety of requirements. Thus, for example, variably manageable fire protection walls, sound insulation walls and / or noise barriers can be realized, which can be pulled out of their upper suspension only when needed and rolled back when not in use.

At some production sites, UV protective walls are necessary, for example for shielding welding workplaces. Again, the winding device according to the invention can be used advantageously. The applications mentioned or parts thereof can be easily realized by means of a winding device, since the different tissue or surface webs can be adapted to the respective purposes and can be rolled out accordingly.

If the terms "surface web" or "surfaces of different textures" are used in the present context, they are basically sections of shielding elements and includes, optionally of different types of fabric such as net mesh fabric or conventional more or less densely woven fabrics, running side by side Lacing, ropes or flat tapes, or may consist of closed surfaces such as plastic or synthetic fiber films or tarpaulins. The sections designed in this way can each be made from natural and / or synthetic fibers or films or the like and preferably have different properties with regard to their permeabilities, for example for light, air, water, but also for dust or other air particles, insects etc. on.

If different surface textures are mentioned, they may in principle mean other physical and / or chemical properties in addition to the properties of light and air permeability and / or impermeability, for example an at least partially imperviousness mentioned above For UV light, for sound o. The like. Depending on the chosen configuration, the winding device can thus satisfy the most diverse uses.

Although in connection with the present description and the following exemplary embodiment usually from a vertically extending cover or from vertically downwards hanging surfaces, tarpaulins o.ä. it is not necessary to make such an arrangement. It goes without saying for the person skilled in the art that even an oblique or horizontal arrangement of the winding device according to the invention is possible and can make sense, in which case it may be necessary to ensure a corresponding tightening of the windable cover element. In particular, in the variants in which both an upper edge and a lower edge is respectively rigidly clamped, suitable lateral guides or clamping elements can be sufficient to prevent undesired sag.

According to a preferred embodiment of the present invention, such a portion of a shielding element extends over the entire width or length of the winding device in the longitudinal direction of the winding elements and corresponds in its length or width approximately the length or width of surface to be covered, so that a single such section with appropriate winding of the winding device can cover the entire surface to be covered. A typical width of a winding device according to the invention may be, for example, up to 20 meters or more. Depending on requirements, however, much larger widths can be covered variably. It will be understood by those skilled in the art that very wide surfaces to be covered may optionally be variably covered with winding devices divided into several sections or segments, where a plurality of winding devices are optionally arranged in parallel, or where only the surfaces are segmented and each on common winding elements be rolled up.

Any number of such sections are each firmly connected to one another at their longitudinal edges, so that the entire shielding element can be of any desired length. According to the invention, such a large proportion of the shielding element is always rolled up onto the at least two winding elements such that the length of the exposed portion of the shielding element covering the surface corresponds at most to the height or width of the surface to be covered.

Within at least two such sections of the shielding element, at least one winding element is arranged according to the invention. The winding elements of the winding device according to the invention are arranged in particular in a central region of their associated surface web and firmly connected at this point with the corresponding surface web, so that upon rotation of the corresponding winding element emanating from its center two-ply winding the respective surface web around the winding element around he follows. Alternatively, two or more winding elements may be arranged within a portion of the shielding. These must each be distributed over the area of the surface web so that they do not interfere with each other during the winding process. For example. When using two winding elements per surface web, the first must be arranged approximately in the upper quarter and the second in the lower quarter of the surface web.

A winding element arranged in the region of the lowermost surface web can optionally be arranged at the lower end of the surface web, so that at least the lowermost surface web can be wound up in one layer from a lower edge. By winding the bottom one Surface track can be an exemption of the surface, eg. The building or room opening, done from below. Furthermore, it is alternatively possible, with an already rolled up lower surface to roll up only the upper winding element and at the same time to fix the lower winding element in its height. Possibly. For this purpose, the lower winding element can be rotatably anchored so that the surface to be covered can not be fully exposed, but can only be optionally covered with one of several surfaces.

According to an advantageous aspect of the present invention, the winding elements are not firmly anchored in the direction of movement of the cover, but perform during the winding process directed in the direction of movement of the cover movement, resulting from the shortening or extension of the exposed surface of the respective surface path. In a hanging embodiment of the present invention, the winding element moves upwards during the winding process and down during the unwinding operation unless another overlying winding element performs a winding operation which compensates for the absolute upward or downward movement of the lower winding element. The winding elements can - like the cover - hang freely in the room. Alternatively, they can engage with side areas which can protrude laterally beyond the cover elements into guide elements, for example guide rails. As already mentioned above, however, optionally one or more of the winding elements can be rotatable and mounted at a predetermined height, so that a complete release of the opening to be covered is not possible, but only an optional covering with one or a partial covering with several of the existing surfaces ,

The drive of the winding elements - these are in particular known winding tubes, winding rods or the like - can be done either manually, by electric motor or otherwise. For example. Engine revolutions can be transmitted to the winding elements by means of cardan shafts, toothed belt or V-belt mechanisms, or motors can each be arranged within the winding elements. Such winding drives are known and not part of the present invention. They are therefore not explained in detail at this point. Examples of drives of winding elements, as they can be used in the context of the present invention, can be found inter alia in the DE 202 14 076 U1 , in the EP 0 567 030 A2 , in the DE 203 20 335 U1 or in the DE 103 36 944 A1 ,

Not all surface webs forming the cover element must have a winding element. It is also possible that a surface web without winding element is involved in the cover, which is then used less variable. For example. It is conceivable that a boundary between two different surface webs is designed by means of an insert from another, in turn differently designed surface track.

Not all surface webs must each have the same length. Basically, almost any different or equal lengths are possible. An uppermost arranged surface web may, for example, at the lower end have a winding element, so that when it rotates a double-layer winding of the first surface web and an adjoining second surface web takes place. The second surface web is preferably longer than the first web, for example twice as long as this. At the lower end, the second surface web can have a further winding element, so that a variable covering of a surface to be covered by means of the first and / or the second surface web or its exposure is made possible with fully rolled up first and second web.

The uppermost arranged surface web has according to the invention on a top edge to a rigid attachment. For example. For example, the upper edge of the uppermost portion of the shielding member may be rigidly secured to a fixed part of the building, for example, to an outer wall, so that the upper end of the winding apparatus is anchored in a fixed position. Alternatively, the attachment can be effected by the connection to a rigid holding device, for example a rail. This rail can in turn be fixedly attached to a part of the building. Alternatively, it can also be combined with a lifting device that can provide for a uniform lifting or lowering of the rail. By means of such a variant, for example, by lowering the entire winding device in the area of the building or room opening into a complete or partial exemption of the building opening from above, without the incidence of light or air circulation is hindered by a fabric web.

According to a preferred embodiment of the invention, a first surface track may be provided to allow air circulation and to release light from outside. For this purpose, this surface web, for example, a wide-mesh fabric or alternatively a number of juxtaposed ropes, cords or the like. A second surface web fixedly connected to the first surface web is, according to the invention, densely woven or of a closed structure, for example a plastic tarpaulin, so that a light incidence is more or less prevented and an air circulation is also more or less prevented. Both surface webs are wound on their respective associated winding elements. By means of such a winding device according to the invention, a surface, for example. A building opening, either completely covered with the first surface web and thus permeable to light and air, or completely covered with the second surface web and thus light and air impermeable, or in any ratio be covered in an upper region with the first surface web and thus light and air permeable and in a lower region with the second surface web and thus light and air impermeable. In particular, in animal stables, this embodiment of the invention is advantageous because it can ensure at any time a zugluftgeschützten, near-ground area, while allowing needs-based ventilation and / or exposure or providing a visual and / or insect protection in the upper area.

The invention makes it possible in a simple manner, by means of the winding device in one operation optionally a ventilation, an exposure, a shading, a visual, insect, wind or rain protection and the area to be covered constantly covered with a portion of the cover hold or alternatively release. In addition, a variety of other applications are conceivable and possible, for example. The realization of variably usable heat, sound, UV or fire walls.

By means of the invention, it is possible to variably cover the area to be covered with the various surface types and to selectively use the different material properties of the individual surface types. For example, alternating mesh fabrics for ventilation and closed fabrics, knits or structures (eg tarpaulins or foils) can be used for wind protection. An im present context referred to as surface or tissue type may consist of different tissues, if their physical properties are similar or the same (eg light or air permeability). The use of bands or ropes, as explained in more detail in the embodiment, can be used to save material and easier installation. In such a variant, the upper, weitmaschigere tissue type may be replaced by vertically extending ropes, cords or ribbons. These are wound or unwound in the same way by the winding element assigned to them as is the case with a fabric or film web.

The invention will be explained in more detail below with reference to preferred embodiments with reference to the accompanying drawings.

The FIGS. 1a to 1f show an embodiment of a winding device according to the invention in different Aufrolllagen, whereby the different coverage conditions are illustrated, which can be realized with the winding device.

The FIGS. 2a to 2f show that too FIGS. 1 equivalent reels of an alternative embodiment of the present invention.

Fig. 3 shows another alternative embodiment of the present invention.

The FIGS. 4a to 4d show schematic side views of a further alternative embodiment of the winding device according to the invention, which is formed from three joined surface webs.

The schematic perspective views of FIGS. 1a to 1f illustrate the design and function of a winding device 10 according to the invention. The winding device 10 comprises in the illustrated embodiment, a cover 11, which is composed of two differently designed surface webs 12, 22. A first surface track 12 is provided with an upper longitudinal side 14 rigidly anchored to a bracket 16. A lower longitudinal side 18 of the first surface track 12 is connected to an upper longitudinal side 20 of a second surface track 22, the lower longitudinal side 24 hang down loosely or can be guided laterally by guide elements, not shown here. Approximately centrally between the upper longitudinal side 14 and the lower longitudinal side 18 of the first surface track 12 there is a first winding element 26, which can provide a rotation for a double-layer winding of the first fabric or surface web 12. As a result, the second surface web 22 is pulled upwards so that a surface 28 to be covered with the second surface web 22 is variably coverable. In the illustrated embodiment, the first surface web 12 is formed as a loosely woven net grid, while the second surface web 22 is more densely woven or from a closed structure - eg. A film or tarpaulin - may exist. On the lower longitudinal side 24 of the second surface track 22, a second winding element 30 is arranged, which can provide by an externally applied rotational movement for a single-layer curling of the second surface web 22 from below.

The schematic perspective view of Fig. 1a shows the winding device 10 in the fully unrolled state. Both surface webs 12 and 22 are shown unrolled here to their respective full length. The cover element 11 can in principle consist of any number of such surface webs, which preferably each have different properties with regard to their permeability to air, light, heat, sound, etc., and thus can be of almost any length.

In the completely unrolled form ( Fig. 1a ), the winding device 10 according to the invention is normally not used in practice, since the cover 11 is significantly longer than the surface to be covered 28. By a corresponding winding of the cover 11 on the winding elements 26, 30, the length of the cover 11 to the size of adapted to be covered area 28.

The area to be covered 28 may, for example, a building opening, a building side wall o. The like. Be. In principle, however, the area 28 to be covered may also be an opening cross-section which is to be opened or closed variably within a building, a hall or another room which can be opened by means of the cover 11 with respect to its permeability to light, air, sound, heat, UV radiation o. The like. Can be variably modified.

In the case of a surface 28 to be covered, the height of which corresponds approximately to the length of the individual surface webs 12, 22, the surface 28 can be variably completely filled with the first surface web 12 (FIG. Fig. 1b ) or completely with the second surface track 22 (FIG. Fig. 1d ) or with the first and the second surface web in any proportions ( Fig. 1c ) or alternatively opened and finally completely uncovered ( FIGS. 1e and 1f ) become.

Fig. 1b illustrates a first operating position of the winding device 10 according to the invention. The second surface web 22 is here almost completely rolled onto the arranged on its lower longitudinal side 24 winding element 30. For example. Thus, it can also expose a surface 32 which is also to be covered underneath the surface 28 to be covered. The first or upper surface to be covered 28 is imposed in the illustrated operating position of the first surface sheet 12, since it is in the fully unrolled state. The winding element 26 arranged within the region of the upper surface web 12 is completely free in this position.

Fig. 1c illustrates a partially rolled up first surface web 12, wherein the first winding element 26 with respect to the representation of the Fig. 1b is rotated, so that the first surface web 12 is partially wound on this and thus shortened. Due to the firm connection of the first and the second surface web, in this case the second winding element 30 can be rotated in such a way that the second surface web 22 is partially unrolled. This can happen, for example, by holding the lower winding element 30. Alternatively, however, the lower winding element 30 can also perform an independent rotational movement by its own drive. The second surface track 22 is tracked in this way to partially cover the area to be covered 28. In simultaneous or synchronous execution of the two rotational movements in this adjustment, the area to be covered 28 at all times covered with the two surface webs 12, 22, it changes only the ratio in which the two surface webs 12, 22 to cover the surface 28th contribute.

In Fig. 1d this ratio is shifted towards the second surface track 22. The first surface web 12 is completely rolled up onto the first winding element 26, whereby the surface 28 to be covered is largely covered by the second fabric web 22. The second winding element 30 can in this case be almost completely rolled out.

The FIGS. 1e and 1f show how by rotating the second winding element 30, a rolling of the second lower surface web 22 and thus exposing the surface 28 from below takes place. In Fig. 1f the fully open position of the winding device 10 is reached, in which the surface 28 is largely exposed.

The FIGS. 1b to 1d can also be understood to mean that the second winding element 30 is rotatably fixed in its height in the region at the lower edge of the surface to be covered 28 and not according to the FIGS. 1a, 1e and 1f can be adjusted in height. In this case, the surface to be covered 28 can not be completely exposed, but only selectively with the first surface 12 (FIG. Fig. 1b ), with the second surface 22 (FIG. Fig. 1d ) or in any division ratio with both surfaces 12, 22 (FIG. Fig. 1c ). In this variant, it is sufficient if only the first winding element 26 is driven and rotated according to the desired coverage condition. The second winding element 30 can passively rotate here, since it is mounted laterally. This requires, however, that is provided for a reverse rotation of the second winding element 30, which, for example, by means of a suitable return spring, a suitable other clamping device o. The like. Can be achieved.

The schematic perspective views of FIGS. 2a to 2f clarify again the corresponding in FIGS. 1a to 1f In the illustrated embodiment, the upper surface web 12 of a plurality of juxtaposed ropes, cords or ribbons, which is analogous to the mesh fabric in FIGS. 1a to 1f be rolled onto the corresponding winding element 26 for varying the covering surface.

The schematic perspective view of Fig. 3 illustrates a further variant in which the second winding element 30 is not arranged on the lower longitudinal side 24 of the second surface web 22, but approximately in the center, so that Also, the second winding element 30 can provide for a two-ply winding the corresponding fabric web 22, as in the first fabric web 12 according to the FIGS. 1a to 1f and 2a to 2f the case is.

It should be mentioned that in the variant accordingly Fig. 3 The lower longitudinal side 24 of the second surface 22 can optionally also be fastened to the lower region of the surface 28 to be covered or the opening, for example by a rigid anchoring. In this case, no complete release of the opening is possible, but only an optional or partial covering with the first surface 12 and the second surface 22. Ggf. In this case, the drives (not shown) of the two winding elements 26 and 30 in a predetermined synchronization - either with fixed rotational ratios to each other - are operated to maintain a uniform and tight clothing and to prevent sagging of the cover 11.

The FIGS. 4a to 4d show schematic side views of another alternative embodiment of the winding device 10 according to the invention, the cover 11 is formed of three mutually joined surface webs 12, 22 and 34.

Fig. 4a illustrates the cover 11 in the fully unrolled state in which the first surface 12 is anchored with its upper longitudinal side 14 rigidly to the bracket 16. The lower longitudinal side 18 of the first surface 12 is connected to the upper longitudinal side 20 of the second surface 22, whose lower longitudinal side 24 is in turn connected to an upper longitudinal side 35 of a third surface 34. Approximately in the middle between upper longitudinal side 14 and lower longitudinal side 18 of the first surface 12, the first winding element 26 is arranged. Also approximately centrally between upper longitudinal side 20 and lower longitudinal side 24 of the second surface 22, the second winding element 30 is arranged. At the lower longitudinal side 36 of the third surface 34, a third winding element 38 is arranged.

The schematic representation of Fig. 4b illustrates the covered with the first surface 12 surface 28. The second surface 22 and the third surface 34 are in this case on the second winding element 30 (double-layered) or on the third winding element 38 (single-layer) rolled up. Second and third winding element 30 and 38 are in this case close to the lower edge of the surface to be covered 28th

The schematic representation of Fig. 4c illustrates the surface 28 covered with the second surface 22. The first surface 12 and the third surface 34 are in this case rolled up on the first winding element 26 (double-layered) or on the third winding element 38 (single-layered). The first winding element 26 is located near the upper edge of the surface 28 to be covered. The third winding element 38 is located near the lower edge of the surface 28 to be covered.

The schematic representation of Fig. 4d illustrates the surface 28 covered with the third surface 34. The first surface 12 and the second surface 22 are in this case rolled up on the first winding element 26 (double-layered) or on the second winding element 30 (double-layered). First and second winding element 26 and 30 are in this case close to the upper edge of the surface to be covered 28. The third winding element 38 is in this case close to the lower edge of the surface to be covered 28th

The in the FIGS. 4a to 4d For example, for the variable formation of a heat, sound and / or light at least partially shielding partition wall in a production hall o. The like. Serve shown. For example, the first surface 12 may be a UV light impermeable layer that allows welding to be performed in an area of the shop floor without affecting the immediately adjacent areas. The second surface 22 may, for example, be a sound-impermeable or noise-insulating layer, which makes it possible to shield adjacent production areas from noisy work. The third surface 34 may, for example, be a heat-insulating layer, which may make it possible to carry out loading or production work with the outer doors open in one part of the hall, without exposing adjacent areas to the weather.
