Definitions

  • the invention relates to a roller shutter for wall or roof openings, in particular in connection with a pivotable roof window, with a roller shutter track, which is composed of shutter bar rods that can be pulled apart to form light slots, or the like, a roller shutter shaft for winding and unwinding the roller shutter track, supports for rotatable mounting of the roller shutter shaft, two side parts adjoining the carrier, arranged in parallel to one another for guiding the lateral ends of the roller shutter track and with an actuating device which a mechanism which causes the opening movement of the roller shutter track and an attacking the free, front end of the roller shutter track, supporting its closing movement or has pulling device.
  • Roller shutters, roof windows or the like are known in various embodiments. They are mostly used to close roof windows mounted in sloping roof surfaces, which have rigidly fixed window frames and window sashes that can be pivoted or tilted about a mostly horizontal axis. Such skylights are sometimes referred to as roof windows, skylights or the like.
  • the pulling device serves the purpose of causing or supporting the closing movement of the roller shutter in the event that the side parts are not vertical or at least not with one are arranged such an inclination that the roller shutter track comes into the closed position only by gravity when the opening mechanism is released.
  • a special roller spring is provided for the pulling device.
  • the pulling device is designed as a pulling rope, which is provided in addition to a pulling rope forming the opening mechanism, so that either an opening or closing movement by pulling on one of the two pulling cables can be initiated. Similar devices are also known in other variants (DE-OS 28 02 078, 27 42 787 and 35 07 015).
  • roller shutter designs have in common that they do not offer sufficient security for the fact that when the roller shutter is closed, the light slots located between the individual roller shutter bars, slats or the like also close. This applies in particular when the pulling device acts on the foremost roller shutter slat and the roller shutter is to be closed when the window sash is partially open, almost horizontally or inclined upwards.
  • roller shutters that closed roller shutter slats or slats are pressed apart in wet frost or snow, as a result of which ice and snow can accumulate in the light slots and damage to the roller shutter track are the result.
  • the roller shutter tracks commonly used tend to tilt laterally when the guides provided in the side parts freeze or become dirty, which can likewise result in damage.
  • the invention has for its object to form the roller shutters of the type mentioned in such a way that it allows a safe closing of the roller shutter track and in particular the light slits even with low roof inclinations or open window sashes and is less sensitive to ice, snow or the like.
  • the pulling device should also be designed using simple structural means such that the forces exerted by a spring are largely freely selectable or can be adapted to the requirements of the individual case and no front extension of the guide body is required.
  • the invention is characterized in that the front and rear ends of the roller shutter track are connected by at least one traction rope, which is fixed at the rear end and attached to the roller shutter track at the front end by means of a spring intended for closing the light slots, and in that the force of this spring is selected so that when an opening movement of the roller shutter track is initiated, the light slots are first opened by the influence of the pulling device and only then is the roller shutter track wound up in the opening direction.
  • the invention has the advantage that the individual roller shutter rods, slats or the like. Between the front and rear ends of the roller shutter track connected via the pull rope and the spring are clamped together and are therefore pre-tensioned in the sense of closing the light slots. As a result, the light slots are kept firmly closed when the roller shutter track is closed or half-open and in the absence of external forces. When the roller shutter track is opened by rotating the roller shutter shaft, however, the light slots open under the influence of the pulling device acting on the front end of the roller shutter track, so that the roller shutter bars can diverge in the manner required for winding onto the roller shutter shaft.
  • the roller shutter according to the invention is therefore far less sensitive to frost, snow, contamination or the like than is the case for conventional roller shutters.
  • a conventional roof window 2 is mounted on the roof 1, which has a window frame 3 surrounding a roof opening and a window sash 5 which is pivotably mounted therein about a central axis 4.
  • two side supports 6 are rigidly attached to the roof 1, e.g. are connected to each other by a lower panel 7 which extends over the width of the frame 3 to form a structural unit which is fixedly mounted on the roof 1.
  • the lower panel 7 preferably has a section 8 bent backwards by 90 °, which is covered with roof panels 9 after it is attached to the roof 1.
  • the two supports 6 preferably consist of square or rectangular plates, the upper edges of which are curved along a sheet 10 running from the back to the front and down.
  • a roller shutter shaft 11 arranged between the carriers 6 are rotatably mounted in the carriers 6.
  • the pivot pins 12 of side parts 14 are pivotally mounted in the carriers 6, which are arranged parallel to one another at a distance corresponding to the distance between the side frame parts of the frame 3 and at their front ends by a foot part 15 arranged perpendicular to them, for example in the form of a hollow body, are connected, which protrudes beyond the associated end of the frame 3.
  • the side parts 14 have extensions 16, which are preferably made of disks or sheets are, which cover the carrier 6 from the outside and extend to the lower panel 7.
  • the side parts 14 and extensions 16 are preferably simultaneously designed as side panels, so that they form a frame together with the foot part 15, which encloses the frame 3 from the outside.
  • the extensions 16 are expediently provided on their undersides with recesses or rounded corners 17 so that they can execute the pivoting movements shown in FIG. 3 about the pivot pins 12.
  • the side parts 14 each have on their inner sides an upper guide 18, which runs parallel to their longitudinal direction, in the form of a groove or the like, in which the lateral ends of a conventional roller shutter track 20 formed from roller shutter bars, slats 19 or the like (FIG 1) are slidably guided, the rear end of which is attached to the roller shutter shaft 11.
  • the rear ends of the guides 18 are preferably brought as close to the support 6 in front of the roller shutter shaft 11 as is possible with the overall construction provided in individual cases and in view of the function described below.
  • At least one extension 22 with a guide pin 23 is attached to the front end of the window sash 5 which can be pivoted outward from the roof 1 when the roof window 2 is opened and which projects into a guide groove 24 of one of the side parts 14 which extends parallel to the longitudinal direction.
  • Such guide pins 23 and corresponding guide grooves 24 are preferably provided on both side frame parts of the window sash 5 and 14 on both side parts.
  • the combination of guide pin 23 and guide groove 24 has the effect that when the window sash 5 is opened, the structural unit consisting of side parts 14, extensions 16 and foot part 15 is pivoted about the pivot pin 12 in the manner shown in FIG. 4.
  • the opening and closing movement of the roller shutter track 20 can be controlled with the aid of roller shutter actuating devices known per se, which are rigidly connected to the roller shutter shaft 11. Since the roller shutter shaft 11 is mounted in the fixedly mounted supports 6 and therefore does not participate in the pivoting movement of the side parts 14, the actuating device can be designed in a largely arbitrary manner.
  • An actuating member of the actuating device can, for example, either be guided near the roller shutter shaft into the space provided with the roof window 2 or be moved to the opposite end of the roof window 2 with the aid of deflection elements guided along the lateral frame parts of the frame 3. This is only schematically shown in FIGS.
  • FIGS. 2 and 3 The function of the roller shutter according to the invention can be clearly seen from FIGS. 2 and 3.
  • the side parts 14 are held in their lower pivot position by the guide pins 23.
  • the roller shutter track 20 can be unwound from or wound onto the roller shutter shaft 11, the roller shutter track 20 describing a convex curve 31 in relation to the axis of rotation 30 of the roller shutter shaft 11 in the space located between the beginning of the guides 18 and the roller shutter shaft 11 .
  • the side parts 14 are mounted by means of the pivot pin 12 so that the roller shutter track 20 enters the guides at all pivoting positions of the side parts 14 along an arc corresponding to the convex arc 31.
  • the position of the pivot pin 12 is preferably selected such that imaginary rearward extensions 18a of the guides (FIGS. 2, 3) are substantially at a distance h from the axis 30 in all these pivot positions, which is at least approximately the maximum winding radius of the roller shutter shaft 11 fully wound roller shutter track 20 corresponds. This can be achieved, for example, in that the pivot pin 12 in the manner shown in FIGS. 2 and 3 in the upper right corner of the carrier 6 and at the same time the axis 30 approximately in the center of the carrier 6 is arranged.
  • the section of the roller shutter track 20 located between the roller shutter shaft 11 and the beginning of the guides 18 is guided in all pivot positions on a convex track substantially corresponding to the arch 31, so that an undesired bending of the roller shutter track 20 upwards is avoided, even if the usual right-handed arrangement is chosen.
  • An unwanted pulling out of the roller shutter track 20 from the guides 18 can be prevented by stops or the like.
  • An upper cover 33 with a rear end 34 covering the lower cover 7 expediently serves to cover the roller shutter shaft 11. At least one front section of the upper cover 33 is combined with the side parts 14 and the foot part 15 to form a structural unit so that it pivots together with the side parts 14 is and thereby forms the required space 35 for guiding the roller shutter track 20 along the arc 31. Because of the arches 10 at the upper ends of the carrier 6, these cannot hinder the pivoting movement of the top panel 33. 2 and 3 it can be seen that the pivot pins 12 can also be arranged in a large number of other locations and in particular can also be mounted on supports other than the supports 6.
  • FIGS. 4 to 8 A preferred embodiment of the invention which favors the secure closing of the roller shutter is explained below with reference to FIGS. 4 to 8, this embodiment together with a roller shutter construction according to FIGS. 1 to 3, but also in combination with other, conventional roof window roller shutters and / or in combination with other roller shutters, e.g. can be used for conservatories, canopies or the like. and wall openings that do not have vertically arranged window frames.
  • the front end of the roller shutter track 20 is formed by a front end rod 37, on the lateral ends of which drawstrings 38 are fastened, the free ends of which are under the influence of a pulling device 39 arranged in the foot part 15 and substantially the length of the Roller shutter track 20 have the appropriate length.
  • the pulling device 39 is preferably designed as a rotatably mounted spring shaft, the spring force of which tends to pull the roller shutter track 20 in the direction of the closed position, ie in the direction of the foot part 20.
  • the function of the spring shaft is analogous to the function of the usual spring shafts used in interior blinds or the like.
  • the usual pawl arrangement or the like is preferably absent, so that the roller shutter track 20 is in any position under the influence of the spring force of the spring shaft.
  • the drawstrings 38 are therefore gradually from when opening the shutter deducted from the spring shaft, however, when the roller shutter is closed, it is wound back onto the spring shaft by the spring force.
  • the spring force is preferably selected so that essentially the same tensile forces result over the entire movement stroke of the roller shutter track 20.
  • other pulling devices 39 provided with motors, slip clutches or the like can also be provided.
  • the roller shutter track 20 is, moreover, preferably composed of the usual roller shutter bars or slats 19 (cf. in particular FIGS. 5 and 6) which are hooked and articulated to one another or to the end bar 37, although other constructions can also be used . Therefore, the individual slats 19 can also be displaced relative to one another to a limited extent parallel to the direction of movement of the roller shutter track 20, so that the characteristic light slots 40 (FIG. 4) can be formed, which also facilitate the winding up of the roller shutter track 20 onto the roller shutter shaft 11 or only make it possible.
  • These light slots 40 are indicated schematically in the upper part of FIG. 5 shown as a top view, while in the lower, broken away part of FIG. 5 the slats 19 directly adjoin one another without these light slots 40, as is the case for the closed position.

  • the pull ropes 41 preferably consist of low-wear and weather-resistant stainless steel wire ropes.
  • roller shutter according to the invention works as follows:
  • the light slots 40 are to be opened, this can be done by acting on the roller shutter shaft 11 by means of the actuating device (27, 29 in FIGS. 2 and 3). If the roller shutter shaft 11 is rotated in the winding direction, the end rod 37 is initially still held under the influence of the pulling device 39, so that only the slats 19 can move and thereby form the light slots 40, which is simultaneously associated with a stronger preloading of the springs 42 .
  • the arrangement is such that the force of the pulling device 39 or the spring force of the spring shaft forming it is greater than the force of the springs 42. If the roller shutter shaft 11 is turned back again, this results in the light slits 40 being closed again under the influence of the springs 42, which were prestressed even more in the pressure direction during the previous opening movement and can now partially relax again.
  • roller shutter track 20 If the roller shutter track 20 is to be partially or fully opened, the opening of the Light slots 40 in the manner described. If the roller shutter shaft 11 is then rotated further, the roller shutter track 20, which is suitably pulled apart, winds up on it, while at the same time the drawstrings 38 are released more and more by the spring shaft or pulling device 39.
  • the shutters 20 can be stopped in any intermediate position by means of detents which are not shown and are appropriately assigned to the actuating device. As long as the roller shutter track 20 is under the influence of the pulling device 39, the light slots 40 remain open, which is favorable for the easy winding of the roller shutter track 20 onto the roller shutter shaft 11.
  • roller shutter shaft 11 If the roller shutter shaft 11 is turned back at a later point in time, the roller shutter track 20 is pulled back in the reverse direction by the pulling device 39, which is now sufficiently tensioned and acts on the end rod 37, and then the light slots 40 close again under the influence of the springs 42 .
  • roller shutter track 20 is held firmly together in the closed position. This results in a high sealing effect, which counteracts in particular icing and the penetration of snow. Furthermore, the roller shutter remains fully functional even when some slats 19 should no longer be in engagement, since their ends are always guided on the pull cables 41, thereby preventing the slats 14 from tilting in the guides 18. This also avoids problems with roller shutters, which frequently occur in roof windows designed as roof hatches, in which the window sashes and roller shutters are additionally mounted such that they can be tilted about a lateral longitudinal axis.
  • the pulling device 39 Since a pulling force always acts on the roller shutter web 20 via the pulling device 39, this cannot tilt or roll up unintentionally even when the roller shutter is tilted. Finally, the pulling device 39 and the springs 42 enable the described function even in skylights with little or no slanted position or with skylights open beyond the horizontal.

  • the entire roller shutter track 20 is wound onto the roller shutter shaft 56 and therefore the pulling element 61 is unwound from the disk 62 as far as possible.
  • the spring 64 is set with a certain preload so that the disk 62 tends to rotate counterclockwise relative to the stationary roller shutter shaft 56. This pulls the tension member 61. If the roller shutter shaft 56 is now rotated counter to the arrow w in order to close the roller shutter (arrow y in FIG. 9), then the spring 64 causes the disk 62 to rotate further against the arrow w and thus winds up the pulling element 61, so that it Tension remains. If the spring 64 is pretensioned sufficiently, the fins 19 are also kept at a distance.
  • roller shutter shaft 56 and the disk 62 thus rotate in the same direction.
  • the invention has the essential advantage that the conditions desired in the individual case can be preselected by means of the outer diameter of the roller shutter shaft 56 and the disk 62. If, for example, by appropriate dimensioning of the diameter of the disk 62, it is ensured that the diameter of the tension member winding located on the disk 62, when the roller shutter is fully open, has essentially the same diameter as the roller shutter track winding located on the roller shutter shaft 56, then the disk rotates 62 when unrolling the roller shutter track 20 initially essentially as fast as the roller shutter shaft 56.
  • the roller shutter shaft 56 then rotates - compared with the disk 62 - faster, whereby the spring 64 is tensioned more and more until it reaches its highest pretension in the closed state.
  • This pretension can be preselected by the disk 62 being rotated correspondingly during assembly relative to the roller shutter shaft 56, and therefore, when using the embodiment according to FIG. 6, it can be set, for example, so that in the closed state it is greater than the force exerted by the springs 42 and therefore when the roller shutter is opened, the light slots which are advantageous for winding the roller shutter track are first formed. When the roller shutter is opened further, this pretension is then gradually reduced again.
  • any other desired states can also be selected, in particular those in which the preloaded spring 64 is initially somewhat relaxed during the closing process and then again tightened again.
  • the invention has the further advantage that the arrangement can be made so that the strongest pulling action only when the front end rod 37 strikes the Foot part 55 is reached and reduced when opening the roller shutter, furthermore the pivotable part of the roller shutter does not require an extension to accommodate the pulling device and the front end of the guide body 53 is not burdened by additional weight.
  • the pulling device described can be used for a large number of different window sizes or roller shutter lengths without significant design changes.
  • the invention is not restricted to the exemplary embodiment described, which can be modified in many ways. This applies in particular to the type, design and arrangement of the springs 42.
  • the latter could be provided with tension springs instead of compression springs or arrangements with only one spring acting on both tension cables 41.
  • all of the features described, individually or in various combinations, can be essential to the invention.
  • the pulling device 39 could, for example, be designed such that it brings about the closing movement of the roller shutter track 20 alone or else e.g. supported closing movement brought about by the roller shutter shaft 11.
  • two completely separate ropes or bands could be provided which interact with the same disc 62 or with two separate discs which are arranged at the same end or symmetrically at both ends of the roller shutter shaft 56.
  • the traction members, deflection elements and disks could be accommodated invisibly in a roller shutter box or in the guide body 52.
  • the deflection elements could be designed differently and arranged at different locations and more or less than the described deflection elements.
  • the invention is not limited to the pivotability of the side parts 14 described with reference to FIGS. 2 and 3. Rather, these can also be connected to a conventional roller shutter box and form a swivel unit as a whole.
  • the invention can also be used for vertical wall windows or doors with correspondingly tiltable sashes with appropriate adaptation.
