Definitions

  • the invention relates to a roller shutter for roof windows, in particular roof windows in pivoting wing construction, which has the features of the preamble of claim 1.
  • the invention has for its object to provide a roller shutter for skylights of the type mentioned with an improved shutter pulling device. This object is achieved by a roller shutter with the features of claim 1.
  • the length compensation device is constructed in the manner of a multi-unit block and tackle and has at least three deflection elements, at least one of which is stationary, the strands of the roller shutter pulling device can be guided, which leads to a considerable reduction in the displacement path of the displaceable deflection elements.
  • the path over which the elastic member must lengthen and shorten is correspondingly reduced.
  • the difference in the tensile force of the elastic member with maximum and minimum elongation can be reduced and the tensile force acting on the roller shutter curtain can be evened out.
  • overextension of the elastic member can be avoided without difficulty.
  • Another major advantage of the solution according to the invention is that it can be used to easily implement either a motorized or a manual drive, and even in the case of manual drive the winding shaft for the roller shutter curtain need not be coupled to a spiral spring generating the winding torque, since Thanks to the length compensation device, the drive torque can be generated by means of a coil arranged on the winding shaft, to which a strand of the roller shutter pulling device is guided.
  • the strands are preferably designed as tapes, since an orderly winding on the spool or spools is then ensured without special measures.
  • roller shutter pulling device has an electric motor, which is preferably integrated in the winding shaft
  • a spool can be arranged on the winding shaft so that it cannot rotate, onto which the common strand of the roller shutter pulling device, which expediently runs in one of the two guide rails, is wound when the roller shutter is closed, so that During the closing process, the strands exert a force on the lower end of the roller shutter curtain in the direction of the cross rail.
  • the coil which can be driven by means of a crank is preferably rotatably mounted in the cross rail or in a housing provided on the underside of the cross rail, the interior of which is connected to that of the cross rail for the engagement of the coil in the cross rail and has, in addition to a first chamber for receiving the common strand, a second chamber for an additional strand with opposite winding direction, which is guided from this chamber to a spool fixedly arranged on the winding shaft.
  • a torque in the sense of winding up the roller shutter curtain is exerted on the winding shaft, or a pulling force is exerted on the lower end of the roller shutter curtain in the sense of closing the roller shutter Directions is achieved.
  • the two chambers of the coil are advantageously separated from one another by a separating plate or the like, at least on the side on which the strands are fed in and out.
  • the partition plate expediently extends to the boundary wall of the cross rail. If the two chambers are each formed by a roller, it can separate these rollers from one another.
  • connection to the crank can be carried out more easily because the angle between the coil axis and the crank axis is relatively small.
  • a universal joint is sufficient instead of a deflection or angular gear.
  • a gearbox can be connected between the crank and the coil shaft that can be driven with it, which can preferably be connected fixedly to the cross rail or, if a housing for the coil is provided on the underside of the cross rail, to this housing.
  • the crank can be permanently coupled to the spool shaft. It is then not necessary to drive through the lower leg of the window sash with a drive shaft. However, if you want to operate the roller shutter even with the window closed, a shaft penetrating this leg of the window sash is required. However, the torque to be transmitted is so low that a relatively small diameter is sufficient for this shaft.
  • strip-shaped light sealing elements are provided according to claim 9, which not only fit against the roller shutter curtain, but also close any gap between the roller shutter and the assigned window sash in a light-tight manner.
  • a roller shutter for an arrangement on the outside of a skylight roof window has a roller shutter box 1 designed in a known manner, in which a winding shaft 2 for a roller shutter armor 3 made of bars is rotatably mounted.
  • An electric motor 4 with a selectable direction of rotation engages in the hollow winding shaft 2 and is connected on the one hand to the latter, on the other hand to the roller shutter box I, so that, depending on the selected direction of rotation, the electric motor can drive the winding shaft 2 in one or the other direction of rotation.
  • a cable leading to the electric motor 4 is designated 5.
  • the roller shutter box 2 is fixedly connected to the upper end of two parallel guide rails 6, which are fixedly connected to a transverse rail 7 at their lower end. Both the guide rails 6 and the transverse rail 7 each form a groove with a rectangular cross section for guiding and receiving the edge region of the roller shutter curtain 3 and a chamber which is rectangular in cross section and adjoins the groove base. As shown in FIG. 1, the two guide rails 6 are divided approximately halfway in the transverse direction and connected to each other by a hinge 8. The lower part of the two guide rails 6 is fixed, its upper part is longitudinally displaceably connected to the frame of the swivel wing that supports it. During the pivoting movement of the pivoting wing, the upper part of the two guide rails 6 and the roller shutter box 1 therefore perform a relative movement to the pivoting wing.
  • a roller shutter pulling device has two textile belts 9, one end of which is attached to the lower end of the roller shutter curtain 3 in the region of one or the other end section engaging in the guide rails 6. From here, the two textile belts 9 are each guided downward to a first deflection roller 10 rotatably mounted in the cross rail 7. From here, the two textile belts 9 run against each other up to a second deflecting roller 11.
  • the two last-mentioned deflecting rollers 11 are rotatably arranged next to one another at half the length of the transverse rail 7 in the guide rail 6 below the groove receiving the roller shutter end. The two second deflection rollers 11 bring the two textile belts 9 together, which then run in the longitudinal direction of the cross rail 7 to a length compensation device designated as a whole by 12.
  • the length compensation device 12 which is arranged in the chamber of the cross rail 7, has a holder 13 which is movable in the longitudinal direction of the cross rail 7 and is shown broken open in FIG. 1 and has a U-shaped cross-sectional profile.
  • Two deflection rollers 14 are rotatably mounted between the two legs of the holder 13.
  • the yoke part of the holder 13 is connected to a prestressed coil spring 15 which extends in the longitudinal direction of the cross rail 7 and on the other hand is firmly connected to the latter.
  • the deflection rollers 14 can therefore move together with the holder 13 against the force of the helical spring 15 in the longitudinal direction of the cross rail against the central zone in which the second deflection rollers 11 are arranged.
  • the two textile belts 9 coming from the second deflection rollers 11 are first guided over the one deflection roller 14 of the length compensation device 12, then run to a third deflection roller 16 which is stationary in the cross rail 17, from this back to the other deflection roller 14 and then in the longitudinal direction of the cross rail 7 to to a fourth deflecting roller 17 arranged in the corner area between it and the one guide rail 6. From there, the two textile belts 9 run in the chamber of the guide rail 6 shown on the right in FIG. 1 against the roller shutter box 1.
  • the roller shutter box 101, the roller shutter curtain 103, the guide rails 106 and the transverse rail 107 have the same configuration as in the first exemplary embodiment.
  • the lower part of the guide rail 106 is also fixed, as is the case there, and the upper part is connected to the frame of the swivel wing in a longitudinally displaceable manner.
  • the winding shaft 102 for the roller shutter armor 103 cannot be driven by a motor. It therefore carries only one coil 119 in a rotationally fixed manner.
  • a length compensation direction 112 is arranged in the chamber of the cross rail 107 and is designed like that of the first exemplary embodiment.
  • the holder 113 shown broken away, with its two deflecting rollers 114 is movable in the longitudinal direction of the transverse rail 107 against the force of the prestressed coil spring 115.
  • Two textile belts 109 one end of which, as in the first exemplary embodiment, is fastened to the lower end of the roller shutter curtain 103, run in the groove of the guide rails 106 to a first deflecting roller 110.
  • the textile belts 109 run against one another to two second deflecting rollers 111 arranged in the middle section of the transverse rail 107. From the latter, the two textile belts 109, which come into abutment here, are deflected to the length compensation device 112.
  • the two textile belts 109 run together to form a spool 120 which is rotatably mounted in the cross rail 107. combine the two textile tapes 109 with a third textile tape before reaching the bobbin 120 and wind only this onto the bobbin 120.
  • the coil 120 either has two chambers lying side by side in the axial direction or, as in the exemplary embodiment, consists of two coil bodies 120 'and 120 "arranged axially next to one another, each provided with two flanges and non-rotatably connected to one another by a shaft.
  • the first coil body 120 ' serves the accommodation of the two textile belts 109.
  • the second bobbin 120 ′′ serves to accommodate a third textile belt 118, which from the bobbin 120 after deflection by a further deflection roller 117 in the chamber of the guide rail 106 shown on the left in FIG. 2 to that on the winding shaft 102 arranged coil 119 extends.
  • the winding direction of the third textile strip 118 in the spool 120 is selected such that it is unwound when the textile strips 109 are wound up and vice versa. Accordingly, the third textile strip 118 is wound up from the spool 120 onto the spool 119.
  • a separating plate 129 penetrated by the shaft is rotatably arranged, which protrudes on all sides over the flanges and where the textile strips 109 and 118 enter between the flanges, that is to say on the yoke part of the cross rail 107 facing side, extends to the transverse rail 107. This precludes the textile tapes 109 and 118 from being able to pass from one bobbin to the other.
  • a crank 121 which lies on the underside of the transverse rail 107, is permanently connected to the shaft of the coil 120.
  • the crank 121 rotates in one direction of rotation, the two textile tapes 109 are wound onto the spool 120.
  • the third textile strip 118 is unwound from the spool 120 and wound onto the spool 119.
  • the crank 121 rotates in the opposite direction, the third textile band 118 is wound onto the spool 120, as a result of which the winding shaft 102 is driven in the winding direction.
  • the roller shutter curtain 103 opens evenly even when the friction conditions change.
  • the coil spring 115 like the coil spring 15, is dimensioned and pretensioned in such a way that the textile strips are always under a sufficiently high tensile force for a uniform movement of the roller shutter curtain and the change in this tensile force does not impair the movement of the roller shutter curtain.
  • FIG. 5 and 6 show, instead of the crank 121 arranged on the underside of the cross rail 107, a crank lying on the inside of the swivel wing can also be provided. 5 and 6 lying parallel to the lower leg of the casement. This crank could also be releasably connected to the swivel wing.
  • An intermediate shaft 122 leads from the inner crank through a bore in the lower leg of the wing to a universal joint 123.
  • the universal joint 123 is connected directly to the shaft of the coil 120.
  • the universal joint 123 is connected to the input of a reduction gear 124, which is located in a housing attached to the underside of the transverse rail 107.
  • the output side of the reduction gear 124 is connected to the shaft of the coil 120.
  • the inside of the two legs which delimit the groove of the guide rail 106 and the transverse rail 107 receiving the roller shutter curtain 103 outwardly and inwardly, is provided with groove-like receptacles 125 which extend in the longitudinal direction of the rail extend.
  • the foot of an elongated light sealing element 126 which in the exemplary embodiment is designed as brushes, is inserted into these receptacles 125.
  • These light sealing elements 126 lie light-tight on the outside or on the inside of the roller shutter curtain 103.
  • the lower leg of the two guide rails 106 is provided with an additional receptacle 127 which is open towards the pivoting wing and receives the foot of an elongated light sealing element 128, which in the exemplary embodiment is also designed as a brush.
  • the light sealing element 128 bears on the lateral legs of the swivel wing, so that no light can pass between these legs and the guide rails 106.
  • the exemplary embodiment shown in FIG. 8 differs from that according to FIG. 2 only by a different arrangement of its coil 220. Therefore, only this difference is explained in the following. For the rest of the details, reference is made to the comments on the second exemplary embodiment.
  • a cuboid housing 230 is attached, which is open to the interior of the cross rail 207.
  • the crossbar is provided with a corresponding opening so that the coil 220 rotatably mounted in the housing 230 into the Cross rail can protrude.
  • the shaft 231 of the coil 220 is parallel to the longitudinal extent of the guide rails 206, which is why a universal joint 232, which connects the shaft 231 to a shaft 233 of a crank which penetrates the sash frame, only needs to adjust to a relatively small angle.
  • the separating plate 229 provided between the two coil formers 220 ′ and 220 ′′ extends, as shown in FIG. 8, from the bottom of the housing 230 to the upper leg of the transverse rail 207.
  • a reduction gear could be provided between the universal joint and the shaft 231, which could be attached to the housing 230 or combined with it to form a structural unit.
