Definitions

  • the invention relates to a planar device specified in the preamble of claim 1.
  • Art Such devices have many uses, such as for closing a passage, an opening or a window, for the separation and distribution of premises, such as gymnasiums, exhibition halls, hospital rooms, the Darkening of a window or a doorway to close another opening, such as a shelf or cabinet, or just for decoration.
  • DE 101 26 812 C2 and DE 101 26 813 C2 describe Roman blinds with differently extending drawstrings, which are wound on a rotatable shaft by means of winding elements, which are rotatably mounted on the shaft.
  • the shaft is supported by a mounting rail.
  • the drawstrings are attached to the curtain track and are removed together with this if necessary from the mounting rail and the shaft with the winding elements, for example, to clean the curtain track.
  • a disadvantage of this arrangement is that during installation of the curtain track very much care must be taken that the take-up be brought into engagement with the windable areas of the pull cords.
  • DE 102 07 021 C1 and EP 1 338 229 B1 describe an elevator device for Roman blinds.
  • the pull cords are guided U-shaped and there is a winding shaft provided on a curtain bar, which has a drive plate which detects the pull cords upon rotation of the shaft.
  • the pull cords are attached to the curtain rail and are removed with this, for example, to clean the curtain rail.
  • the curtain web can also be removed in the subject of this document only when it has reached its maximum stretched position, that is completely lowered. Otherwise, the cords are wrapped around the winding shaft and a release is not possible.
  • the DE 20 2005 020 590 U1 describes a device for the orderly winding the drawstrings of a Roman blind.
  • a winding shaft is likewise provided, on which two coils are provided for each pull cord, which is guided in a U-shaped manner. These coils in turn have drive plates which capture the drawstring and wind up in an orderly manner.
  • a large cost of materials associated with high costs is necessary if the Roman shade should be made wide and thus contains many drawstrings.
  • the curtain can be dismantled only in the lowered state, otherwise, as with the other devices, the pull cord is wound on the winding shaft and thus the curtain can not be solved with the drawstrings of the winding shaft.
  • the DE 20 2006 005 531 U1 also describes a device for shirring a curtain.
  • the curtain has Einzelzugschnüre, which must be fixed in a clamp located on a winding shaft.
  • the curtain can be dismantled only in the fully lowered state and the assembly and disassembly is relatively expensive especially for wide curtains, since each individual pull cord must be clamped in the corresponding disc or taken out of this.
  • the DE 44 39 423 C1 and DE 94 11 309 also describe a Roman blind with a take-up shaft, which has a driver, which detects the U-shaped pull cords and wound on the take-up shaft. Again, the disassembly of the curtain can only be done with completely lowered curtain. It may also be here that the Buchschnurmit vide the drawstrings are not or not fully recorded, so that no or at least no uniform winding and thus shirring of the curtain is possible. Since here the take-up shaft has a relatively large diameter, the device is quite clunky, which can bring aesthetic disadvantages.
  • the DE 20 2006 010 779 also shows a Roman shade with a rotatably mounted shaft on which a carriage is rotatably mounted and longitudinally displaceable.
  • This carriage includes a drive plate and is to bring with a coupling piece in operative connection.
  • Positioning and counter-positioning means exist between the carriage and the coupling piece in order to align the drive disk and the drawstring as well as possible so that the drive disk can also catch the drawstring.
  • a release of the curtain fabric is only possible with completely lowered curtain.
  • the entire device is relatively clunky, since the transmission must sit between the drive means and the shaft for the translation of the rotational movement.
  • the object of the invention is therefore to avoid the aforementioned disadvantages and to provide a flat device in which the surface part can be mounted and dismantled in any possible Hochziehlage, being ensured during assembly that the surface part comes into operative connection with the drive part and wherein the drive part can be formed as narrow and slim as possible to allow assembly, for example, in the window reveal.
  • the drive part has a first gear part, wherein the surface part has a second gear part.
  • these two gear parts are in operative connection with each other, wherein the drive and the surface part are releasably secured together.
  • This has the advantage that is moved by the two gear parts of the surface part with its winding element by the drive means, whereby a raising or lowering of the surface sheet is made possible. Since the winding element is mounted on the surface part, the surface part can be mounted and dismantled in any position of the surface sheet. This is particularly advantageous for heavy and unwieldy surface sheets, such as shutters and roller shutters, but also for smaller and lighter surface sheets, such as blinds and Roman blinds. So there is no "zero position" of the surface track for assembly and disassembly.
  • the device works, no matter whether the surface web itself, as is usually the case with roller shutters, shutters and the like, is wound onto the winding element, or whether pull cords are used, as is the case, in particular with blinds, Roman blinds and blinds. So there are many possible applications for the present invention.
  • a clip connection can be provided in a preferred embodiment, wherein the drive and / or the surface part have at least one clip element.
  • Such Clip connection is easy to produce and also just as easy to solve, so that no special tools must be used for assembly and disassembly.
  • the first and / or the second gear parts are designed as gears. These provide a simple and robust way to transmit the rotational movement from the drive part to the winding element.
  • the Fig. 1 and 2 each show individual parts of the surface part 20 and the drive part 40.
  • the first 42 and second gear parts 24 are shown and that without being engaged with each other.
  • the first gear part 42 is in this case integrated in a carriage 43, which has two side boundaries 44. These side boundaries 44 simultaneously act as counter positioning means 45 for the positioning means 33 on the surface part.
  • the positioning means 33 are formed by side walls 32 of the assembly 31, which comprises the winding element 30.
  • This winding element 30 comprises a coil 34 having a winding region 35, wherein the second gear part 24 is arranged on the coil 34.
  • This coil 34 and the positioning means 33 are arranged on a support plate 37.
  • the support plate 37 may be sewn to the surface panel 21.
  • a riveting, gluing or other connection is possible.
  • Fig. 2 shows the assembly 31 and the carriage 43 engaged with each other.
  • the positioning means 33 and the Gegenposition réellesstoff 45 which are formed here by the side walls 32 and the side boundaries 44, the first 42 and second 24 gear parts are aligned. Errors during assembly are minimized.
  • a clip connection is provided to releasably connect the drive member 40 to the surface portion 20, it is particularly advantageous to provide the two elements of the clip connection on the sidewalls 32 and side margins 44, since then the clip connection and positioning can occur simultaneously. As a result, fewer components are needed and the device can be produced more cheaply.
  • Fig. 3 shows a planar device 10 using the example of a Roman blind.
  • Fig. 1 and 2 known assembly 31 and the carriage 43 mounted. Only the second gear part 24 is visible, since the first gear part 42 is covered by this.
  • the winding element 30 is designed as a coil 34.
  • the coil 34 has in its winding area 35 guide elevations 36.
  • a particularly targeted winding of the pull cord 60 is possible, which serves as a device of the surface part 20, which is wound onto the winding element 30.
  • the pull cord 60 is attached with its one end 61 at the lower end 22 of the surface panel 21 63, as will be explained later. With its other end 62, however, the pull cord 60 is attached to the winding element 30, in this case by a fixed connection.
  • the drawstring 60 is executed here as a cord; However, it is also possible to provide as a drawstring 60 a band or the like. Also, here the entire assembly 31 is arranged on a support plate 37, which forms a rider, which is attached to the upper end 23 of the surface panel 21. As a result, a particularly quick and easy installation of the unit 31 is possible.
  • the shaft 46 can still be seen, which in the present case connects the carriage 43, comprising the first gear part 42, to the drive means 41 (not illustrated here). It is of course also possible a plurality of slides 43 and a plurality of first gear parts 42 through the shaft 46 with each other or with the Drive means to connect. This provides a simple way to bring the drive means 41 in operative connection with the first transmission part 42, so that the first transmission parts 42 are moved upon actuation of the drive means 41. Of course, it is also conceivable to connect the second gear parts 24 or the winding elements 30 or the assemblies 31 with a shaft 46.
  • first 42 and / or the second gear part 24 can be formed as a shaft 46.
  • This shaft can then have, for example, teeth and have a gear-like cross-section. As a result, components are saved and the device can be made even more compact and narrower.
  • the corresponding parts 24, 30, 31, 42, 43 are mounted on the shaft 46 in a rotationally fixed but longitudinally displaceable manner.
  • the non-rotatable mounting is necessary to transmit the rotational movement of the drive means 41 to the other parts.
  • alignment of the carriages 43 with the structural units 31 or the first gear parts 42 with the second gear parts 24 is simpler. Also manufacturing tolerances and the like can thereby be compensated easier.
  • the shaft 46 is here designed as a square shaft to allow this.
  • connection means 70 is provided, which is designed in the present case as a Velcro connection.
  • a connection means 70 is provided, which is designed in the present case as a Velcro connection.
  • a Velcro connection is favorable, since the Velcro and Velcro bands are also flexible and can be easily attached to the material of the surface sheet 21.
  • a cover 80 which covers the shaft 46 and the gear parts 24, 42 and the winding element 30.
  • This also results in the assembly in a window reveal from inside and outside no unattractive picture, for example, by the take-up mechanism is shown. It is particularly advantageous to carry out the drive part 40 in one piece with the cladding 80, since this facilitates the assembly of the surface part 20 on the drive part 40 and reduces the production costs.
  • the cladding has approximately the shape of a U-profile, since on the one hand this represents a very simple design and on the other hand the second gear parts 24, the winding elements 30 or the assemblies 31 can be clipped into the cladding 80.
  • This also creates a simple, clip connection that works fast. and can be solved and manufactured without tools. This is also much simpler than providing clip elements on the individual components, as it can happen here ever easier for such clip elements to break off or be damaged.
  • this clip connection is also particularly advantageous if the components in the panel 80 are longitudinally displaceable. As a result, the assembly of the surface part 20 on the drive part 40 is greatly facilitated and the alignment of the gear parts 24, 42 simplified to each other. It is also possible here to carry out a particularly compact and slim design.
  • the 4 and 5 show again the combination of carriage 43 and assembly 31 in side view or in partial section.
  • the side boundary 44 of the carriage 43 in this case has an opening for the square shaft 46, which can connect the carriage 43 with further carriage 43 and with the drive means 41.
  • the assembly 31 is also arranged here on a support plate 37.
  • Both gear parts 24, 42 are in this case designed as gears. Even if in Fig. 5 the teeth are only partially shown, both gear parts 24, 42 are to be understood as full gears.
  • FIG. 6 now shows a complete planar device 10, here also as Raffvorhang.
  • the device 10 has a surface part 20 and a connecting part 40.
  • the surface part 20 has a surface web 21, which is shown here in partial Rafflage.
  • the surface web 21 has a plurality of drawstrings 60 which are fastened with their one end 61 at the lower end 22 of the surface web 21 63, wherein they are assigned to the winding elements 30 with its other end 62.
  • attachment 63 it is conceivable to knot the drawstrings 60 in designated elements, but also set them by sewing, gluing or the like.
  • Each pull cord 60 passes through a series of guide means 64, for example eyelets, pockets or loops. This makes it possible to determine the pull cords 60 arranged on the surface web 21.
  • Each pull cord 60 is in this case assigned its own winding element 30, which makes it possible to carry out these winding elements 30 as small as possible and space-saving.
  • the drive part 40 has a plurality of carriages 43, which are interconnected by a shaft 46. Also connected to the shaft 46 is the drive means 41, which is designed here as a chain drive 47. It is of course also possible to provide other drive means 41, such as drive rhythms, drive belts or the like. It is of course conceivable as drive means 41 to provide a motor.
