Definitions
- the invention relates to a Venetian blind with at least one pull chain, the chain links of which are articulated to one another and to Venetian blind, slat-like blind bars and to at least one adjustment chain, the chain links of which are articulated to one another and to the Venetian blind bars.
- Such shutters are known for example from EP-A-330 192, EP-A-189 091 and DE-A-34 37 346.
- roller shutters When manufacturing and installing roller shutters, several tasks should always be performed at the same time. Firstly, the roller shutter slats with the tension and adjustment chain links assigned to them should have a cross section that is as constant as possible over the entire width of the roller shutter in order to ensure that the roller shutter is rolled up safely and in a space-saving manner. Secondly, there should be as few gaps as possible between the individual components and the stationary guides in which the roller shutter is guided, in order to prevent the blind, the penetration of e.g. To prevent water or dust or the use of burglary tools. Thirdly, the outer front of the closed roller shutter should have the most uniform and even and therefore pleasing appearance. From these points of view, the roller shutters known from EP-A-330 192 and DE-A-34 37 346 have significant disadvantages.
- roller shutters Another task is to make the roller shutters as compact and inexpensive as possible. This means that the pull chain and in particular the adjustment chain should be arranged as far as possible on the edge of the roller shutter and using as few components as possible and the blind bars should be machined as little as possible and subsequently weakened in some areas.
- roller shutter known from EP-A-189 091 has the disadvantage that either partial slats are provided for connecting the pull chain links to the connecting supports or the slats must be provided with corresponding recesses for the pull chain links or the adjusting elements.
- the object of the invention is to provide a blind which can avoid the described disadvantages of the prior art.
- this object is achieved in that the adjustment chain links overlap the pull chain links.
- blind bars at least partially overlap the pull chain links.
- the invention can be further developed in that the connecting joints between the pull chain links and the blind bars are in the region of the upper longitudinal edge of the blind bars and / or in that the connecting joints between the adjusting chain links and the blind bars are in the lower region Longitudinal edge of the blind bars.
- this can be characterized in that the joints of the pull chain links are aligned with the joints of the adjusting chain links in the closed state of the roller shutter. In this way, the roller shutter in the roller box can be rolled up easily and tension-free.
- one of the two hinge eyes of the pull chain links or the adjusting chain links is an elongated hole.
- This embodiment ensures that the blind bars after they have been pivoted downwards, that is to say they have been closed, can be moved even further towards one another, so that it is possible, inter alia, to lock the lamella-like blind bars by means of suitable devices, which will be described later, and to prevent them from being opened accidentally or by force .
- the joints between the pull chain links and / or the adjustable chain links by the pull chain links or Adjusted chain links are provided with profiled guides, by means of which the pull chain links or the adjustable chain links are connected to one another.
- a particularly simple connection of the blind bars to the pull chain links can be characterized in that the connecting joints between the blind bars and the pull chain links are arranged approximately below the connecting joints between the respective pull chain links.
- the particular advantage of this embodiment is that the connections between the Venetian blind rods and the pull chain links do not influence or interfere with the connections between the pull chain links, which simplifies both the manufacture of the individual components and the assembly of the roller shutter.
- a groove is provided on the lower longitudinal edge of the blind bars and / or the adjustment chain links, which groove, in the closed state of the roller shutter, cooperates with a web which acts in the area of the upper longitudinal edge the pull chain links or the blind bars and / or the adjustment chain links is provided, or that webs are provided on the lower longitudinal edge of the blind bars and / or the adjustment chain links, which interact positively with webs of the adjacent pull chain links or blind bars or adjustment chain links in the closed state of the roller shutter.
- Roller shutters are usually guided with their lateral edges in stationary guide profiles which are attached to the openings to be closed.
- an extension is provided on the pull chain links, over which the pull chain links are guided in fixed guide profiles in the installed state.
- a problem when installing roller shutters, especially in very wide openings, e.g. Showcase is that the blind bars can bend due to their own weight, whereby a safe function of the roller shutter is no longer guaranteed. Furthermore, especially with wide wall openings, the resistance of the blind bars is so low that there is only very little protection against burglary.
- the pull chain links extend over the entire width of the roller shutter.
- the pull chain links create a "basic roller shutter", so to speak, which can be designed in accordance with the desired strength requirements and in which the Venetian blind bars can be stored over their entire length, so that both the problem of the unwanted bending of the Venetian blind bars and the low resistance to burglary is solved.
- the pull chain links have openings which are delimited by webs. The width of the webs and the openings between the webs can be designed according to the respective requirements.
- the pull chain links consist of profile bars which extend in the longitudinal direction of the roller shutter bars and are connected to one another via webs.
- the profile bars can be produced as semi-finished products in any length, cut off if necessary in approximately the width of the roller shutter of appropriate length and can be connected by means of any number of webs of the desired width, so that with respect to Width of the roller shutter and the strength of the pull chain links, which is determined by the shape and number of webs, gives maximum flexibility.
- the overall cross section of the roller shutter slats it is desirable for the overall cross section of the roller shutter slats to be as constant as possible over the entire width of the roller shutter.
- the common overall cross section of the pull chain links and the adjustment chain links in the closed state of the roller shutter corresponds essentially to the cross section of the roller shutter slats.
- the roller shutter can be designed to such an extent that free spaces are provided on the pull chain links, in which, when the roller shutter is closed, the connecting joints of the adjusting chain links and optionally the slide chain links are accommodated.
- the connecting joints of the adjusting chain links and optionally the slide chain links are accommodated.
- a recess is provided on one part and a tab on the other part, which can be bent into the recess.
- an angular part is pivotally mounted on the uppermost blind rod or on the uppermost link of the blind chain is that can cooperate with a hook-shaped, stationary part.
- the hook-shaped part has a hook at its lower end, that it has a vertical, downwardly open slot that has a passage opening for the angular part at its upper end that the passage opening is at least partially covered by spring bands and that it has spring bands inclined obliquely downward from the hook towards the roller shutter, which form an extension of the slot between them.
- the hook-shaped part is resilient and has a horizontally extending slot in its upper region, that the lower edge of the slot is formed by a deflecting part pointing obliquely upward away from the roller shutter and that the upper edge of the slot is formed by a deflecting part which projects obliquely downward from the roller shutter and projects beyond the deflecting part, this embodiment being distinguished by its particular simplicity.
- the shape of the roller shutter slats and the design of the chain links have a significant influence on the winding diameter of the roller shutter when it is wound up in the roller box.
- the winding diameter can be influenced not only by the structural design of the roller shutter bars themselves, but also by the shape of the shaft on which it is wound in the roller box.
- a shaft is provided for winding up the roller shutter, the outer radius of which, measured by the axis of rotation of the shaft, is smaller in one area than on the rest of the circumference of the shaft.
- the shaft has an approximately polygonal cross-section and that one side of the polygon is closer to the axis of rotation of the shaft than the other sides of the polygon. With this measure, the outer contour of the wound part of the roller shutter can be smoothed even further.
- webs projecting inwards are provided on the shaft, the inner surfaces of which lie on the circumference of a circle, the center of which coincides with the axis of rotation of the shaft.
- a drive motor can be mounted eccentrically in the shaft, so that the shaft moves eccentrically around the axis of rotation of the motor when the motor is driven.
- the shaft has an inner diameter, at least partially determined by webs projecting inwards from the shaft, the center of which is eccentric to the axis of rotation of the shaft, a larger motor can also be accommodated in the shaft, whereby the shaft bearing is arranged eccentrically in the shaft or to the motor bearing.
- a particularly simple fastening of the lamella to the shaft is possible if a groove running in the longitudinal direction of the shaft is provided in the shaft, in which a bolt or the like can be received for fastening the roller shutter to the shaft.
- the uppermost or first slat of the roller shutter is connected to the shaft via a spring band or the like, which offers the advantage that the first slat does not have to be attached directly to the shaft.
- the spring band prefferably fastened in the groove of the shaft by means of a bolt or the like and to wrap it around the shaft approximately once, whereby this
- Embodiment offers the advantage that the length of the roller shutter, which is accommodated in the roller shutter in the fully lowered state of the roller shutter and is therefore not visible, is not both expensive and space-consuming

- Fig. 42 shows how the roller shutter according to the invention is rolled up on a shaft with a polygonal cross section and the
- FIG. 43 and 44 show two embodiments of shafts improved according to the invention, on which a roller shutter is wound.
- a part of a roller shutter slat is shown in oblique view, which is composed of a Venetian blind slat 1, a pull chain link 2 and an adjustment chain link 5.
- the pull chain link has fork-shaped extensions 16 at one end and a shoulder 17 at the other end, which carry the articulated eyes of the pull chain link.
- the pull chain link 2 also has an extension 6 running in the longitudinal direction of the roller shutter rod, which in the present exemplary embodiment extends under the adjustment chain link 5 through and up to stationary guides for the roller shutter, not shown.
- the blind rod 1 has a tab 30 and the adjustment chain link has a tab 35, with which both extend over the pull chain link 2. In this way, any gap extending through the entire shutter bar is avoided.
- the pull chain link 2 and the adjustment chain link 5 have cross sections which together in the state shown in FIG. 1 essentially correspond to the cross section of the blind rod 1. In this way, a constant, continuous cross-section of the roller shutter rod is created, which is both when winding the roller shutter onto a
- Fig. 3 it is shown in section how a sliding chain link 3 is inserted over the extension 6 of the pull chain link 2 and is positively connected to it via a dovetail-like guide.
- simple slide caps can also be placed over the extension 6.
- the sliding chain links 3 or sliding caps have the task of adapting the roller shutters to any groove width of a fixed guide groove, for example provided on the masonry of a window opening, in order to ensure good sliding and a sound-damped running of the roller shutter. A lateral displacement of the slide chain parts or slide caps can be prevented, for example, by indentations.
- the slide chain link 3 shown in FIG. 3 has a slot-shaped recess 26 at one end and a shoulder 24 at the other end, which can be inserted into the slot-shaped recess 26 of the next slide chain link and connected to the latter via a bolt 24.
- pull chain links 2 and the adjustment chain links 5 have extensions 8 and 16 limited slot-shaped recesses, as well as approaches 9 and 17, to be connected via bolts 7, 19 to the adjacent adjustment chain links 5 and pull chain links 2.
- the blind bars 1 and the adjustment chain links 5 have on their lower longitudinal edge a groove 15 which can interact with a web 14 provided on the upper longitudinal edge of the blind bars 1.
- the roller shutter slats can be moved against each other in the direction of movement of the roller shutter.
- the pull chain links and the adjustment chain links, as well as the slide chain links which may be provided have slot-like bores 20, 21 and 22 on their webs 17, 9 and 24, in which the bolts 7, 19 and 25 are slidably received. This makes it possible for the pull chain, the adjustment chain and possibly the slide chain to be “pushed together” and consequently also for the blind bars 1 to be pushed together and locked on tongue and groove.
- the elongated hole 22 in the slide chain link 3 can have a slot 23 into which the bolt 25 can be hooked in a simple manner.
- the adjustment chain links 5 are articulated in the region of their lower end via a bolt 12 in a bore 13 in the adjustment chain link 5 and a bore 13 'in the blind rod 1.
- the blind rod is articulated to the hinge pin 7 of the pull chain links.
- the slide chain link 3 has a bore 27 which the bore 13 in
- Slide chain link 5 corresponds.
- This bore 27, although it actually has no function, can be present if the adjustment chain link 5 and the slide chain link 3 have the same cross-section, i.e. e.g. were made with the same extrusion tool. If the sliding chain links 3 are produced with another tool, the bore 27 can of course be omitted. In this case, larger roundings can also be provided on the outer edges 28 of the sliding chain links 3 in order to enable better sliding of the sliding chain links 3 in the fixed guides.
- the pull chain link 2 shown, inter alia, in FIG. 5 can have an unchanged cross section, but under
- FIG. 8 and 9 show how the roller shutter according to the invention can be opened, the adjustment chain being omitted in FIG. 9.
- the sliding chain links 3 and 4 of FIGS. 3 and 4 are shown connected to form a sliding chain, the elongated hole 22 of the sliding chain 3 having a slot 23, whereas the elongated hole 22 of the sliding chain link 4 is closed.
- the stationary guide groove 71 is indicated in broken lines, with B being a wider guide groove and C being a narrower guide groove 71.
- FIG. 12 An embodiment is shown in FIG. 12 in which the sliding element is attached as a cap 33 to the extension 6 of the pull chain link 2.
- the tip 34 of the sliding cap 33 can either be removed, as shown in FIG. 12, or not, as is indicated in FIG. 12, to bring the roller shutter to a wider guide groove B to adjust.
- the extension 6 has a smaller width than the pull chain link 2, thereby creating free spaces 10 and 11.
- the joints 8, 9; 26, 24 of the adjustment and slide chain links can be easily accommodated, which on the one hand does not result in any dimensioning problems in the design and arrangement of the joints, since each roller shutter slat in this area should have the same overall cross section as the blind bar 1 and on the other hand the connecting bolts 19, 25 Adjustment 5 and slide chain links 3 can be aligned with the articulated or connecting bolts 7 of the pull chain links 2 with one another and with the blind bars 1, as a result of which a common pivot axis is defined for all chain links.
- the joints between the individual chain links formed by means of bolts in corresponding bores or the connecting joints between the pull chain links and the pivotable blind bars are replaced by profiled guides which run in the longitudinal direction of the roller shutter bars.
- the joints between the pull chain links 2 are formed on the one hand by essentially U-shaped grooves 40 with an inwardly bent leg 41 and on the other hand by webs 42 which have a hook-shaped extension 43 at their free end that can be received in the groove 40.
- the connection of the web 42 to the groove 41 can, for example, take place in such a way that the web 42 of a pull chain link 2 is inserted into the groove 40 of an adjacent pull chain link 2 in the longitudinal direction of the blind rod.
- the pivotability of such an articulated connection is shown in FIG. 18, for example.
- Tension chain links 2 which are overlapped by the adjustment chain links 5, in the region of the grooves 40 and webs 42
- the blind bars 1 are also articulated to the pull chain links 2 via profiled guides.
- the joints are here similar to the joints between the pull chain links 2 and the adjustment chain links 5 on the one hand by grooves 44 with inwardly bent legs 45, 46, which are arranged on the pull chain links 2, as well as webs 47 with hook-shaped projections 48, which on the upper Longitudinal edges of the pivotable blind bars 1 are provided. How the pivoting of the Venetian blind rods 1 on the pull chain links 2 can take place is e.g. shown in more detail in FIG. 20.
- Fig. 14 it is further shown that the pivotable shutter rods 1 have at their lower longitudinal edge a groove 49 running in the longitudinal direction of the roller shutter rod, to which a web 50 on the upper longitudinal edge of the adjacent pull chain link 2 is assigned.
- the blind bars 1 can be locked in the manner already described in the form of the tongue / groove system against unintentional or violent opening when the pull chain links 2 are pushed completely towards one another.
- the grooves 40 of the joints between the individual pull chain links 2 and the adjustment chain links are made so deep that the webs 42 with the hook-shaped projections 43 of the adjacent pull chain links 2 and adjustment chain links 5 in the direction of movement of the roller shutter, i.e. are displaceable in the grooves 40 transversely to the longitudinal extent of the roller shutter slats.
- adjustment chain links 5 To lock the adjustment chain links 5, they are equipped on their lower longitudinal edge with grooves 51 and on their upper longitudinal edge with webs 52, so that the adjustment chain links 5 can also be locked in the form of a tongue and groove connection.
- FIG. 13 shows an embodiment of roller shutter bars 1 which are not fastened to the pull chain links 2 in a way that cannot be louvred.
- roller shutter slats are usually used as the top roller shutter slats of a roller shutter, which are not designed to be blinds.
- the roller shutter slats 1 In order to connect the non-blind roller shutter slats 1 firmly and positively to the pull chain links 2, the roller shutter slats 1 have a shoulder 53 in the region of their lower longitudinal edge and the pull chain links have an associated shoulder 54, so that here too a
- roller shutter rod 1 Longitudinal direction of the roller shutter rod is formed guide, which prevents the roller shutter rod 1 can be detached from the pull chain link 2 or pivoted away.
- Roller shutter bars 1 can be pivoted against each other.
- the pull chain links 2 with the pivotably mounted blind bars 1 and the associated adjustment chain links 5 can be mutually opposed be pivoted.
- Fig. 19 it is shown that the pivotable shutter rods 1 are locked via groove 49 and spring 50 against swinging open when the pull chain links 2 are pushed completely against each other.
- a major advantage of the embodiment described in connection with FIG. 16 with pull chain links extending over the entire width of the roller shutter in connection with profiled guides as connecting joints is that a continuous connection of the pull chain links with one another and with the over the entire width of the roller shutter Blinds 1 is given, which is both very easy to manufacture and assemble.

- spring straps 87 are fastened on both sides of the slot 85 and extend further downward from the hook 84 and obliquely towards the roller shutter.
- the free ends 122 of the spring bands 87 are rounded in order to avoid damaging or scratching the roller shutter when they are in contact with the roller shutter.
- the spring bands 87 extend into the area of the rectangular passage opening 86 and prevent the roller shutter hook 81 from engaging with the spring hook 82 when the roller shutter is lowered.
- the roller shutter hook 81 falls outwards due to its own weight or by a spring, as soon as it has left the roller box (not shown). Subsequently, when the roller shutter is lowered, the roller shutter hook 81 is pressed in the direction of the roller shutter again by the upper ends 89 of the spring straps 87, then by the hook part 83 and finally by the lower ends 122 of the spring straps, until it is again outwardly below the ends 122 can fall.
- roller shutter hook 81 With its crossbeam 90 being pressed outwards over the lower ends 122 of the spring straps 87 on the spring straps 87 until it slides has passed the hook 84. If the roller shutter is now lowered again, the roller shutter hook 81 remains with its crossbar 90 in the hook 84 and the blind bars 1 are held and opened via the adjustment chain when the roller shutter is lowered further.
- the roller shutter hook 81 slides upward through the slot 85, the crossbar 90 passes through the passage opening 86 and slides upward at the upper ends 89 of the spring bands 87, these being bent in the direction of the roller shutter until the crossbar 90 of the roller shutter hook 81 releases them and they can spring outwards again.
- the spring hook 82 can pivot inwards to the window opening or the like, that is to the left in FIG. 35, and lies against the upper edge of the wall opening.
- the hook part 83 is laterally slightly displaceable and can thus adapt to the lateral position of the roller shutter hook 81.
- 37 and 38 show a further substantially simplified embodiment of a spring hook 82, which only consists of a single component, for example stamped from spring steel.
- 37 and 38 consists of a fastening part 91 and a spring part 92, which are separated from the fastening part 91 by slots 93 and 94, which are delimited by webs 95 and 96.
- the spring part 92 consists of an upper spring part 92 'and a lower spring part 92 ", which are separated from one another by a transverse slot 97.
- the spring part 92" has a hook 102 at its lower end.
- the lower spring part 92 “has a deflecting part 98 pointing upward away from the roller shutter, which delimits the transverse slot 97 on its underside
- the upper spring part 92 ' has a deflecting part 99 pointing downward away from the roller shutter which delimits the transverse slot 97 on its upper side and which projects beyond the upper edge of the deflection part 98.
- the spring part 92 ' also has an inlet part 100 which points upwards away from the roller shutter.
- the roller shutter hook 81 which is approximately L-shaped in the present exemplary embodiment, first slides inwards on the deflection part 100, then on the upper spring part 92 ' below until it can fall slightly outwards and then slides further down on the deflection part 91 and from the lower spring part 92 'until it can fold outwards under the hook 102. If the roller shutter is pulled up again for blinds, the roller shutter hook 81 slides outwards and over the hook 102, the lower spring part 92 "being bent towards the roller shutter until it is in the hook when the roller shutter is lowered again 102 can hook in. The roller shutter can now be opened as already described.
- roller shutter hook 81 slides upwards until it is pressed back over the deflection part 98 and under the deflection part 89 through the slot 97 to the roller shutter and can thus pass through the spring hook 82.
- a fold 101 may be provided, which results in a shortening of the fastening part 91.
- the fastening part 91 can further have bores 103, e.g. to be screwed onto a stationary guide profile 71 for the roller shutters.
- the fold 101 can also be used as a stop lug for the stop on the underside of the box in which the roller shutter is rolled up, which considerably simplifies the measuring work during assembly.
- FIG. 39 shows an embodiment of a spring hook 82 which is considerably simplified compared to the embodiment shown in FIGS. 37 and 38. 39 also consists of a fastening part 91 and a spring part 92, a hook 102 being provided at the lower end of the spring part 92.
- the spring hook is in a roller box 123 or the like. arranged, the front, free side 124 is angled and protrudes with its lower longitudinal edge obliquely downwards and away from the wall opening, outwards.
- a stationary guide rail 71 is also indicated, which can be designed as known per se.
- the spring hook 82 in turn has bores 103, with the aid of which it can be screwed or riveted to the roller box 123 or an extension of the guide rail 71.
- the spring hook 82 is arranged in the angled region of the front wall 124 of the roller box 123 and bears on the upper longitudinal edge 125 thereof, or is only slightly spaced from it. As a result, the roller shutter hook 81 slides down first on the front wall 124 and then immediately on the side of the spring hook 82 facing the roller shutter without being able to engage in the hook 102 when the roller shutter is lowered.
- roller shutter hook 81 slides outward with its crossbar 90 on the hook 102, the spring part 92 with the hook 102 being bent toward the roller shutter until the crossbar 90 has passed the hook 102. If the roller shutter is then lowered again, the roller shutter hook 81 can hook onto the hook 102 and the roller shutter can be opened.
- the angled part of the front wall 124 of the roller box 123 assumes the function of a deflecting part and the roller shutter hook 81 is pivoted further and further inward as the roller shutter continues to be raised, with the spring part 92 of the spring hook 82 also following springs inside until the crossbar 90 of the roller shutter hook 81 has passed the spring hook 82 and the latter can spring back outwards in the direction of the front wall 124.
- the spring hook 82 shown in FIG. 39 in connection with the angled front wall 124 of the roller box 123 not only has the advantage that the spring hook 82 is of a very simple construction, but also the advantage that the spring hook 82 is completely accommodated in the roller box 123, which is not just visual advantages, but also provides protection against damage to the spring hook 82.
- FIG. 39 part of the front wall 124 has been shown broken out in FIG. 39, the outer contour of the front wall 124 being shown in dash-dot line for better illustration of the structure.
- spring hooks and roller shutter hooks shown in FIGS. 35 to 39 are not restricted to any particular structure of a roller shutter, but can be used with any roller shutter.
- roller shutter hook 81 shown in FIGS. 37 to 39 is very flat, it is not absolutely necessary that it is received in a recess in the blind rod 1, but it can e.g. also lie directly on the first blind rod 1 on the outside.
- a recess 105 is provided on the web 42 of the pull chain link 2 and on one leg 106 of the groove 40 a flap 109 is formed by two cuts 107, 108, which are bent into the recess 105 in the assembled state of the articulated connection 40, 42 can.
- a recess on one or both legs 41 or 106 of the groove 40 and to bend a tab provided on the web 42 into one of these recesses.
- this form of securing can be used not only with the pull chain links 2 with one another, but also with the connection between the adjustment chain links 5 and the connection between the blind bars 1 and the pull chain links 2, as well as with the slide chain links 3, 4 or the connection between the slide chain links 3, 4 and the pull chain links 2.
- Fig. 42 an octagonal shaft is shown on which a roller shutter according to the invention is wound, wherein it can be seen that the roller shutter by the aligned bolts 7, 19 and 25 of the tension, adjustment and slide chain links is problem-free winding.
- the shaft 43 shows a shaft 111 on which a roller shutter is completely wound.
- the shaft 111 has an axis of rotation 112 and is supported by bearings, not shown, in the roller box, also not shown.
- the shaft 111 has an approximately polygonal cross section with rounded sides and edges, an area 113 of the polygon being less distant from the axis of rotation 112 of the shaft 111 than the rest of the circumference of the polygon.
- a groove is provided in which a bolt 114 is received.
- a spring band 115 is fastened to the shaft 111 via this bolt 114, which is wound about once around the shaft 111 and is connected at its other end to the first or uppermost lamella 77.
- This first lamella 77 abuts the shaft 111 approximately in that region 113 on which it has the smallest outer radius.
- the slat 77 is offset radially inward by approximately the amount of its thickness, so that no bulge forms when the subsequent slats are wound over the slat 77.
- an outermost winding circle 116 is formed overall, which has its center in the axis of rotation 112 of the shaft 111, the circumference of the rolled-up roller shutter having no bulge.
- the outermost winding diameter of the roller shutter can thus be reduced by twice the amount of eccentricity of a bulge present in the prior art, which ultimately results in a smaller construction of the roller shutter.
- the shaft 111 has webs 117 which project inwards and run in the longitudinal direction of the shaft 111, the region 113 of the shaft 111 which is offset inwards opposite web 117 is longest.
- the surfaces of the webs 117 facing the axis of rotation 112 lie on a circle 118 whose center lies on the axis of rotation 112 of the shaft 111.
- Shafts, not shown, or a motor for driving the roller shutter or the like are accommodated by the webs 117.
- a further embodiment of the shaft 111 is shown, wherein the webs 117 are either shortened or omitted in comparison to Fig. 1, so that a larger space was created in the interior of the shaft 111 in which a larger motor od. Like. Can find space.
- the center 119 of a circle 120 which can now be written into the shaft 111, is eccentric to the axis of rotation 112 of the shaft 111.
- the motor mount 121 or the shaft bolt is attached in the axis of rotation 112.
- the shaft 111 now runs eccentrically again and compensates for the bulge, so that the ideal smaller diameter 116 can be wound again.
- the roller shutter which can be louvered has at least one pull chain, the chain links 2 of which are connected to one another in an articulated manner and to pivotable, lamella-like louver bars 1 and at least one adjustment chain, the chain links 5 of which are articulated to one another and to the louver bars 1, on.
- the adjustment chain links 5 overlap the pull chain links 2 and preferably the blind bars 1 also overlap the pull chain links 5 at least partially.
