Description

  • The invention relates to a Venetian blinds according to the preamble of claim 1.
  • In roller shutters that can be louvered, the individual roller shutter slats are connected in an articulated manner to tension and adjustment chain links, so that the roller shutter slats can be pivoted from a roller shutter position, in which the opening behind them is fully closed or covered, into a blind position, in which the View between the roller shutter slats pivoted in this way is possible. Due to the blind device required for pivoting these roller shutter slats, special guide rails are usually required for the installation of the roller shutters. These guide rails usually have to be wider than those of normal roller shutters in order to be able to pivot the Roller shutter slats required to accommodate Venetian blind device or parts thereof. The consequence of this is that it is difficult to retrofit normal roller shutters already present in buildings with blinds that can be shut, because the frames and guides that are present in a fixed position have to be replaced by those with larger dimensions. It is obvious that it would be expedient to design roller shutters of this type in such a way that they can be installed in guide rails or guide profiles already present on site for normal roller shutters without a blind device.
  • Roller shutters which can be blinded and which enable such retrofitting of existing systems are already known from FR-A-2 553 467 and (EP-A-0 189 091). According to EP-A-0 189 091, the blindable roller shutter slats are connected at their upper ends by pull chain links and at their lower ends by adjustable chain links. The pull chain links and the adjustment chain links are designed at one end in the manner of an eye and at the other end in the manner of a fork, so that adjacent chain links can be assembled in a hinge-like manner. The roller shutter slats are accommodated between a pair of adjacent tension and adjustment chain links. This type of construction alone makes it impossible to move the roller shutter slats into a closed tongue and groove position, where the tongue formed in a roller shutter slat can be moved into a groove formed on the adjacent roller shutter slat to form a burglar-proof roller shutter lock.
  • Furthermore, the known blinds for the two chains consisting of tension and adjustment chain links require a further chain of guide chain links provided on the edge of the roller shutter bars, which are guided in the fixed guide profiles. The guide chain links are designed as slot chain links and are connected to one another in a hinge-like manner by slot bushings, that is to say bushes provided with a longitudinal slot. The roller shutter slats are suspended by means of a hinge pin, which corresponds axially with the to align slot bushings of the guide chain links. Here, the slotted bushings are designed as connecting elements for the guide chain links so that they can withstand the loads from the chain links underneath and the roller shutter bars underneath. Furthermore, the slot bushings are to be designed so that they can accommodate the hinge pins for the articulation of the roller shutter slats. Another function that these slotted sleeves have to fulfill is that the slotted sleeves must enable the pivot pins for the suspension of the shutter slats to be inserted into the slits of the slotted chain links during the transition from the roller shutter position to the blind position. Thus, the connection of the guide chain links must be designed according to the various functions, which is complicated and, moreover, makes it difficult to accommodate guide chain links designed in this way in existing guide rails for normal roller shutters. Another disadvantage is the fact that the articulation points for the articulation of the roller shutter bars on the guide chain links must be aligned axially with the axes of the slot bushings, which in turn results in structural restrictions for the roller shutter construction. For the transition from the roller shutter position to the blind position, appropriate stops must also be formed on the roller shutter bars and on the guide chain links, as well as on an extension support to be provided on the lowest roller shutter bar. Overall, the well-known Venetian blinds have a complicated structure and malfunctions are not excluded. The winding circumference is also comparatively large due to the adjustment and pull chain links applied to the front surface and to the rear surface of the roller shutter bars. Another disadvantage is that due to the three chains and the essentially band-like design of the pulling and adjusting chain links, there is a limitation in the available clear width for the blind-capable or for the viewing area.
  • The object of the invention is to provide a roller shutter which is simple and robust and which enables reliable shuttering. Furthermore, the roller shutter should be able to be accommodated in existing guide profiles for normal roller shutters without difficulty and should have a winding diameter comparable to that of a normal roller shutter during winding.
  • This object is achieved by the features contained in the characterizing part of claim 1, expedient developments of the invention being characterized by the features contained in the subclaims.
  • According to the invention, the pull chain links and the adjustment chain links are arranged laterally at the two ends of each roller shutter slat, side by side and in alignment with one another, so that the chain links practically represent a lateral extension of the roller shutter slats. As a result, the roller shutter slats on the front and rear surfaces do not build up by the thickness or strength of the chain links, which has a favorable effect on the winding diameter of the Venetian blind. If the pull chain links and adjustable chain links are adapted in their cross-sectional dimensions to the cross-sectional dimensions of the roller shutter slat and thus run essentially flush with the front and rear surfaces of the roller shutter slats, the winding diameter is practically the same as that of a normal roller shutter without a blind device. As a result of the lateral arrangement of the chain links in alignment with the roller shutter bars, there is no overlap of the roller shutter bars by the chain links, which allows the clear width of the blinds opening area to be maximized. This optimization is particularly important if at least the adjustment chain links are designed to be narrow in the manner of lamellae. Furthermore, the pull chain links can be used as guide elements for the roller shutter slats, with the result that a chain pull is opposite the conventional state of the art is eliminated. This arrangement also allows the components required for the blind movement to be accommodated within the cross-sectional dimension of the roller shutter slats.
  • In the closed state of the roller shutter, when the chain links are adapted to the shape of a roller shutter slat, the roller shutter curtain is completely smooth and flush.
  • Due to the arrangement of the elements required for the blinds in alignment with the roller shutter rod, the roller shutter that can be rolled up behaves as if the blinding device were not present at all. This also prevents malfunctions, i.e. unintentional blinds.
  • Also essential is the decoupling achieved according to the invention between the articulated chain links on the one hand and the joints, which are required for the pivotable mounting of each roller shutter bar on the associated tension and adjustment chain links. This makes it easy to design the chain links as well as the links to hold the roller shutter slats. Simple hinge pins can be used for the chains, which have to bear the entire weight of the roller shutter hanging underneath in the upper area. On the other hand, the hinge pins for the storage of the roller shutter slats only have to take up the weight of the individual roller shutter slats. This also makes the blind movement easier. Furthermore, a clean separation between the chain joints and the blind joints is achieved, which in turn prevents the blind movement from being triggered unintentionally. In particular, the articulation points for the articulation of the roller shutter rod to the chain links can be displaced from the vertical plane of the chain articulation pins, which results in lever arms which favor the blind movement. Overall, the design of the components required for the blinds is simplified, which is advantageous for the manufacture of the blinds Roller shutter affects.
  • In this context, it is expedient to shift the hinge pins into insertable profiles arranged on the edge of the roller shutter slats, so that the roller shutter slats can be designed and manufactured regardless of the shutter movement.
  • If the upper longitudinal edges of the roller shutter slats are designed as springs, i.e. as a projecting nose and the lower longitudinal edges as a groove, which is complementary to the springs, the roller shutter slats can be moved into a tongue and groove position, which results in burglar protection. This movement into and out of the tongue and groove position can be absorbed or compensated for in a structurally simple manner on the pulling and adjusting chain links by corresponding longitudinally displaceable guidance of the chain link pins.
  • The pull chain links are advantageously formed in several parts, in particular in two parts, which brings advantages in terms of production technology and enables the incorporation of a reinforcing insert made of steel. The pull chain links can be hollow for reasons of material savings, the cavity can be foamed if necessary.
  • The shutter movement can be triggered by different mechanisms, but a hook is expediently formed on an adjustment chain link or roller shutter rod or an insertion profile arranged thereon, which cooperates with a counter-hook to trigger the shutter movement. The counter hook is expediently arranged such that it can be deflected so that the hook can be guided past the counter hook for the normal roller shutter function.

  • In the embodiment according to FIGS. 1 to 4, each roller shutter slat 1 is assigned a pull chain link 2, which are connected to one another to form a pull chain 3. The roller shutter or roller shutter slats are guided in conventional U-shaped profiles 4, which are fastened to the walls of the building in the region of the opening to be closed by the roller shutters. For the blind-like adjustment of the roller shutter slats 1, adjustment chain links 5 are provided, one link each one end of a roller shutter bar 1 is assigned analogously to the pull chain links. The adjustment chain links 5 are interconnected to form an articulated adjustment chain 6.
  • It is obvious that the pull chain links 2 and also the adjustment chain links 5 are arranged vertically one above the other in the respective chain hoist. The pull chain links 2 and adjustment chain links 5 provided at the two ends of each roller shutter bar 1 are arranged next to one another in accordance with FIG. 2 and, as can be seen from FIG. 1, in alignment with the corresponding roller shutter bar 1. This has the advantage that the tension and adjustment chain links 2 and 5 do not apply in their strength or thickness to the roller shutter rod 1, so that with this arrangement the measure of space saving often implemented in the prior art by forming recesses in the front - And rear surface of the roller shutter slats 1 can be dispensed with, which are otherwise connected to a weakening of the roller shutter slat. Another advantage of this arrangement is that when the roller shutter is wound up, the winding diameter is determined only by the thickness of the roller shutter bars 1, i.e. the inclusion of a blind device on the winding circumference itself does not change anything.
  • The pull chain links 2 are articulated to one another. In the exemplary embodiment shown, each pull chain link 2 has at its lower end a fork 7 formed from two legs delimiting a recess between them and at the upper end an articulated eye 8 which engages between the fork recess. When the fork 7 and the eye 8 interlock, a hinge-like joint is obtained between the pull chain links 2, including an articulated bolt 9.
  • The joint-like connection of the adjustment chain links 5 also takes place in an analogous manner, the fork being designated by 10, the joint eye by 11 and the joint bolt by 12.
  • 1, 3 and 4, the hinge eyes 8, 11 of the tension and adjustment chain links 2, 5 have an elongated hole 13, in each of which the hinge pin 9 and 12 is guided relatively longitudinally. The elongated holes 13 have the purpose of making it possible to retract the roller shutter slats 1 into a tongue and groove position and to move them out of this position, as can best be seen in FIG. 4 and will be explained in more detail below.
  • Each roller shutter slat 1 is articulated at its two ends to a pulling and adjusting chain link 2 and 5, in order to enable the roller shutter slat 1 to move in a louvered manner. According to FIG. 2, each roller shutter slat 1 is connected via a hinge pin 14 to an associated pull chain link 2 and by means of a hinge pin 15 to an associated adjustment chain link 5. Since the hinge pin 14 must be guided past the adjusting chain link 5 due to the aligned arrangement of the pull chain link, adjusting chain link and roller shutter bar, the adjusting chain link 5 is provided on its rear surface with a corresponding recess 16. The hinge pin 14 is here in the upper area of the pull chain link 2, whereas the hinge pin 5 in the lower area of the adjustment chain link 5. The hinge pins 14 and 15 of a roller shutter rod 1 are offset with respect to one another with respect to the vertical plane, and preferably in the range from 4 to 5 mm, as indicated by the two arrows in FIG. 1 at 17. This offset of the two hinge points to each other favors the initiation and execution of the shutter movement of the roller shutter slats 1. The displacement of the hinge pins 14 and 15 in the roller shutter slats 1 takes place in the embodiment according to FIGS. 1 to 4 in socket-like profile sections 18, as can be seen in FIG. 1 below results. These profile sections 18 are components of the profile of either the roller shutter rod 1 or of an insertable or attachable profile at the ends of the roller shutter rod 1. When assembling the pull chain links, adjustable chain links and roller shutter slats, these parts are only put together laterally, so that the hinge pins 14 and 15 engage, in particular snap, into the corresponding bush-like profile sections 18.
  • 1 to 4 is best explained with reference to FIGS. 3 and 4, in which FIG. 4 shows the normal roller shutter position, in which the opening is closed by the roller shutter slats, and FIG. 3 the blind position shows, in which the roller shutter slats are pivoted out of the vertical plane into a more or less strong inclined position, so that there is a possibility of inspection between the roller shutter slats.
  • To close the roller shutter, the roller shutter is unwound in the usual way, the pull chain links 2 being guided in the lateral U-profiles 4. The closed position is reached as soon as the bottom roller shutter bar hits the bottom and the other bars sit up one after the other, in the illustrated embodiment a strip-like part 19 arranged at the bottom of the opening to be closed by the roller shutter with a nose-shaped projection 20 into a groove 21 at the lower longitudinal edge of the roller shutter rod 1 engages or the roller shutter rod is moved onto the projection 20. Since each roller shutter rod 1 is formed with a nose-shaped projection 20 at its upper end and with a complementarily shaped recess 21 at its lower end (see also FIG. 1), the roller shutter rods 1 can be inserted into the tongue and groove shown in FIG. Position are moved in which the roller shutter slats 1 are aligned one above the other along a vertical. In this tongue and groove position, burglar protection is ensured because the individual roller shutter slats 1 cannot be lifted from the outside.
  • If the roller shutter slats 1 are to be blinded, the roller shutter slats 1 must be moved out of their tongue and groove position. To compensate for this movement, the elongated holes 13 are provided in the articulated eyes 8 and 11 of the pull and adjustment chain links 2 and 5. Only in this excavated Position the roller shutter slats can be blinded.
  • It should also be noted here that in the case of roller shutter slats which can be louvered, the uppermost roller shutter slats, generally the uppermost three to five roller shutter slats, are generally not designed to be louvered, but only those below. However, since this is a generally known fact, this is not specifically discussed in the present. In any case, the adjustment chain link of the uppermost roller shutter slat in the illustrated embodiment has a hook 22, which serves to trigger the blind movement. With this hook 22, a counter hook 23 interacts, which sits on a steering lever 24, which is articulated at 25 to a stationary part, for example on the U-profile 4. Above the counter hook 23 there is a deflecting member 26 with an inclined surface 27, the deflecting member 26 being guided on a rod 28 in the exemplary embodiment shown and being biased into its lower position by a spring 29. When the roller shutter curtain is lowered, the hook 22 moves past the counter hook 23 because the steering lever 24 is pivoted outwards when the hook 22 hits the inclined surface 27. For blinding, the roller shutter armor is to be lifted from a tongue and groove position by pulling up the roller shutter belt, the hook 22 running past the counter hook 23 coming from below, which is also favored here by an inclined surface 29 which brings about a deflection of the steering lever. If it is pulled up further, the hook 22 presses the deflection member 26 upward against the spring preload, the hook 22 finally being able to easily pass the deflection member 26 as a result of the deflection of the steering lever 24 when the hook 22 is further raised. For the blinds, however, the hook 22 is only moved over the counter hook 23 and then lowered again, the hook 22 then interacting directly with the counter hook 23, since the steering lever is no longer deflected due to an inclined surface. When the roller shutter is lowered further, the hook 22 hooks, so that the adjusting chain links 5 are held in their vertical position, but the pull chain links 2 are further lowered, so that the blinds of the roller shutter bars 1 occur. If the blind position is to be lifted, the belt is tightened again so that the pull chain links 2 are raised and finally, after the roller shutter bars 1 are largely pivoted in alignment with the pull chain links 2, the hook 22 is moved out of the engaged position and the roller shutter armor is pulled upwards can. Here, the associated tension, adjustment chain links and roller shutter slats are again aligned vertically so that the roller shutter curtain can be wound up like a normal roller shutter curtain. This means that the pull chain links and adjustable chain links are flush with the roller shutter slats, which is made possible by the arrangement of the elements in alignment with one another. When rolling up, the blinds that can be rolled up therefore do not build up more (no larger roll diameter) than a normal blind without a blind.
  • In the embodiment according to FIGS. 5 to 8, the same reference numerals have been used for the same components. In this embodiment, which is also shown largely schematically using only part of the roller shutter, the pull chain links 2 are formed in two parts, the halves being designated by 2a and 2b. This two-part training has advantages in terms of production technology because the pull chain links are hollow and made of plastic and can be plugged together to form the pull chain link. In this way, largely the same wall thicknesses can be achieved, which is advantageous in terms of production technology. In particular, as a result of this division in two, a lamellar steel insert 2c can be arranged between the profile halves 2a and 2b, which results in an increase in strengthening. Such an embodiment is particularly suitable for roller shutters with a corresponding length and width. The displacement of the parts at 30 can be explained by the fact that the pull chain links must be passed above and below to receive the hinge pin 9. From the illustration on the right in FIG. 5, the rolling shutters 1 move into one another in the tongue and groove position due to the interlocking of the nose-like projections 20 and the recesses 21. The likewise very narrow adjustment chain link 5 is bifurcated at 31 to receive the lower end of the overlying adjustment chain link in a hinge-like manner.
  • At 32, a tongue formed laterally on part 2b can be seen, which can also be seen in FIG. 4 and which covers the adjustment chain link 5 from behind and thus prevents a view between the pull chain link and the assigned roller shutter rod 1 in the closed position of the roller shutter curtain.
  • The hinge pin 14 shown in FIG. 6 for the articulated suspension of the roller shutter bar 1 also serves as fastening of the two halves 2a and 2b of the pull chain link 2. In the embodiment according to FIG. 6, both the hinge pin 14 and the hinge pin 15 are in an insertion profile 33 of the Roller shutter rod 1 is shifted, which can be inserted laterally into the open end of the roller shutter rod 1. As a result, the roller shutter rod 1 can be produced as a component of corresponding lengths that is contoured over the entire length and can be cut to the desired length of the roller shutter rod during production.
  • FIG. 7 shows the roller shutter slats 1 in the normal closed position and FIG. 8 the roller shutter in the blinded position of the slats 1, 1 ′ denoting the fixed roller shutter slat which has already been explained above. In Fig. 8, the stationary guide profile 4 for guiding the roller shutter bars 1 or the pull chain links 2 is shown schematically below.
  • An embodiment variant of the hook can also be seen from FIG. The hook 22 is resiliently articulated on the adjustment chain link of the uppermost roller shutter slat 1, so that the hook 22 can be pivoted inwards when winding up the roller shutter slats 1 and thus no longer interferes with the winding up of the roller shutter slats 1. As soon as unwinding of the roller shutter slats 1, the hook 22 is released, it pivots into the position shown in FIG. 8, where it interacts with a fixedly arranged counter hook 23 for triggering the blind movement. From Fig. 8 below hook-like end configurations of the hinge pins 14 and 15 can be seen, which when plugging together engage behind corresponding latching configurations on the roller shutter rod 1 or insert profile 33, so that the hinge pins 14 and 15 can be firmly locked. For assembly, the pull chain links, the adjustment chain links and the roller shutter bars 1 need only be put together by plugging them together via the hinge pins. As can be seen, the articulation of the roller shutter slats 1 on the adjustment chain links and the pull chain links is completely independent and thus decoupled from the connection of the pull chain links and adjustment chain links to form a chain with one another, so that the hinge pins 14 and 15 have to be dimensioned in terms of strength only to accommodate the weight of a roller shutter bar.
